**PRESENTATION OF FINANCIAL AND OTHER INFORMATION**

**General**

In this annual report, the terms "Santander Brasil," the "Bank," "we," "us," "our," "our company" and "our organization" refer to Banco Santander (Brasil) S.A. and its consolidated subsidiaries, unless otherwise indicated. References to "Banespa" mean Banco do Estado de São Paulo, S.A. – Banespa, one of our predecessor entities. The term "Santander Spain" means Banco Santander, S.A. References to "Santander Group" mean the worldwide operations of the Santander Spain conglomerate, as indirectly controlled by Santander Spain and its consolidated subsidiaries, including Santander Brasil.

All references herein to the "*real*," "*reais*" or "R$" are to the Brazilian *real*, the official currency of Brazil. All references to "U.S. dollars," "dollars" or "U.S.$" are to United States (or "U.S.") dollars. All references to "euro," "euros" or "€" are to the common legal currency of the member states participating in the European Economic and Monetary Union. References to "CI$" are to Cayman Islands dollars. References to "£" are to United Kingdom pounds sterling.

Solely for the convenience of the reader, we have translated certain amounts included in "Item 3. Key Information—A. Selected Financial Data" and elsewhere in this annual report from *reais* into U.S. dollars using the exchange rate as reported by the Brazilian Central Bank (*Banco Central do Brasil*), or the "Brazilian Central Bank," as of December 31, 2025, which was R$5.5024 per U.S.$1.00, or on the indicated dates (subject, on any applicable date, to rounding adjustments). We make no representation that the *real* or U.S. dollar amounts actually represent or could have been or could be converted into U.S. dollars at the rates indicated, at any particular exchange rate or at all.

Certain figures included in this annual report have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be an arithmetic aggregation of the figures that precede them.

**Consolidated Financial Statements**

We maintain our books and records in *reais*, our functional currency and the presentation currency for our consolidated financial statements.

This annual report contains our consolidated financial statements for the years ended December 31, 2025, 2024 and 2023. Such consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or the IASB (currently referred to by the IFRS Foundation as the "IFRS accounting standards") and the interpretations issued by the IFRS Interpretations Committee (formerly known as the International Financial Reporting Interpretations Committee). Our consolidated financial statements for the years ended December 31, 2025, 2024 and 2023 have been audited by PricewaterhouseCoopers Auditores Independentes Ltda., an independent registered public accounting firm, whose report and unqualified opinion is included herein.

IFRS differs in certain significant aspects in comparison with U.S. GAAP. IFRS also differs in certain significant aspects in comparison with the Brazilian GAAP. Appendix I to our audited consolidated financial statements for the years ended December 31, 2025, 2024 and 2023, included herein, contains information relating to certain differences between IFRS and Brazilian GAAP.

**Market Share and Other Information**

We obtained the market and competitive position data, including market forecasts, used throughout this annual report from internal surveys, market research, publicly available information and industry publications. This data is updated to the latest available information as of the date of this annual report.

**Calculation of Net Promoter Score**

Net Promoter Score, or NPS, is a widely recognized research methodology used to measure customers' willingness to recommend a company, its products, and its services. It assesses overall customer satisfaction and brand loyalty. The survey is distributed to customers in a random, representative sample and measures satisfaction on a scale from zero to 10. An example of the survey question is: "What are the chances of you recommending Santander to a friend or relative? Please respond on a scale from zero to 10."

&nbsp;&nbsp;&nbsp;&nbsp;• Responses of nine or 10 are considered "promoters";

&nbsp;&nbsp;&nbsp;&nbsp;• Responses of seven or eight are considered "neutral"; and

&nbsp;&nbsp;&nbsp;&nbsp;• Responses of six or less are considered "detractors."

An NPS score is calculated by the percentage of promoters less the percentage of detractors, thus using the total responses as a basis. The higher the number, the higher the measure of customer satisfaction. The grading scale can be negative 100 points to positive 100 points. The NPS calculation does not give weight to customers who did not respond to the survey question. To ensure greater consistency in NPS scores by increasing the response volume and extending the observation period, we evaluate scores using a 90-day period. This approach aggregates all responses over three months and recalculates the score, helping to minimize the effects of seasonal fluctuations during the evaluation period.

Our NPS score, as calculated by us in December 2024 and December 2025, was 61.8 points and 59.2 points, respectively.

(\*) The average annual balance sheet data has been calculated based upon the average of the monthly balances at 13 dates: at December 31 of the prior year and for each of the month-end balances of the 12 subsequent months.

(1) "Net interest margin" is defined as net interest income (including dividends on equity securities)
divided by average interest earning assets.

(2) "Adjusted return on average stockholders' equity," "Average stockholders'
equity excluding goodwill as a percentage of average total assets excluding goodwill" and "Impaired assets as a percentage
of stockholders' equity excluding goodwill" are non-GAAP financial measures which adjust "Return on average stockholders'
equity," "Average stockholders' equity as a percentage of average total assets" and "Impaired assets as
a percentage of stockholders' equity" to exclude goodwill arising from acquisitions made in previous reporting periods, as
further discussed in note 13 to our audited consolidated financial statements included elsewhere in this annual report. Our calculation
of these non-GAAP financial measures may differ from the calculation of similarly titled measures used by other companies. We believe
that these non-GAAP financial measures supplement the GAAP information provided to investors regarding the substantial impact of the goodwill
arising from acquisitions made in previous reporting periods. Accordingly, we believe that the non-GAAP financial measures presented are
useful to investors. The limitation associated with the exclusion of goodwill from stockholders' equity is that it has the effect
of excluding a portion of the total investment in our assets. We compensate for this limitation by also considering stockholders'
equity including goodwill. For a reconciliation of our selected ratios, see "—Reconciliation of Non-GAAP Measures and Ratios
to Their Most Directly Comparable IFRS Financial Measures."

(3) Credit risk exposure is the sum of the amortized cost amounts of loans and advances to customers (including
impaired assets), guarantees and private securities (securities issued by nongovernmental entities). We include off-balance sheet information
in this measure to better demonstrate our total managed credit risk. The reconciliation of credit risk exposure to the most comparable
IFRS measure is disclosed in the table of non-GAAP financial measures presented immediately after these notes.

(4) Total funding is the sum of financial liabilities at amortized cost and financial liabilities at fair
value in income held for trading, excluding other financial liabilities. For a breakdown of the components of total funding, see "Item
5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Liquidity and Funding."

***Reconciliation of Non-GAAP Ratios to Their Most Directly Comparable IFRS Financial Measures***

The information in the table below presents the calculation of specified non-GAAP financial measures to the most directly comparable IFRS financial measures. Our calculation of these non-GAAP financial measures may differ from the calculation of similarly titled measures used by other companies. We believe that these non-GAAP financial measures supplement the GAAP information provided to investors regarding the substantial impact of the goodwill arising from acquisitions made in previous reporting periods and the significance of other factors affecting stockholders' equity and the related ratios, as further discussed in "Item 4. Information on the Company—A. History and Development of the Company—Important Events" and in note 13 to our audited consolidated financial statements included elsewhere in this annual report. The limitation associated with the exclusion of goodwill from stockholders' equity is that it has the effect of excluding a portion of the total investment in our assets. We compensate for this limitation by also considering stockholders' equity including goodwill, as set forth in the above tables. Accordingly, while we believe that the non-GAAP financial measures presented are useful to investors and support their analysis, the non-GAAP financial measures have important limitations as analytical tools, and investors should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP measures including under IFRS.

**3D. Risk Factors**

This section is intended to be a summary of more detailed discussions contained elsewhere in this annual report. You should carefully read and consider the following risks, along with the other information included in this annual report on Form 20-F. The risks described below are not the only ones we face. Additional risks that we do not presently consider material, or of which we are not currently aware, may also affect us. Our business, results of operations or financial condition could be impacted if any of these risks materialize and, as a result, the market price of our units and of our ADRs could be affected.

**Summary of Risk Factors**

***Summary of Risks Relating to Brazil and Macroeconomic and Political Conditions in Brazil and Globally***

&nbsp;&nbsp;&nbsp;&nbsp;• The Brazilian government has exercised significant influence over the Brazilian economy. The Brazilian
government's macroeconomic management strategies, new rules as well as political and economic conditions, could adversely affect
us and the trading price of our securities.

&nbsp;&nbsp;&nbsp;&nbsp;• Inflation, government efforts to control inflation, and changes in interest rates may hinder the growth
of the Brazilian economy and could have an adverse effect on us.

&nbsp;&nbsp;&nbsp;&nbsp;• Exposure to Brazilian federal government debt could have a material adverse effect on us.

&nbsp;&nbsp;&nbsp;&nbsp;• Fluctuations in interest rates and other factors may affect our obligations under legacy employee pension
funds.

&nbsp;&nbsp;&nbsp;&nbsp;• Exchange rate volatility may have a material adverse effect on the Brazilian economy and on us.

&nbsp;&nbsp;&nbsp;&nbsp;• Infrastructure, labor force deficiency and other factors in Brazil may impact economic growth and have
a material adverse effect on us.

&nbsp;&nbsp;&nbsp;&nbsp;• Disruption or volatility in global financial and credit markets, including as a result of the ongoing
war between Russia and Ukraine and uncertainties following the ceasefire agreement in the Middle East and tariff increases implemented
by the United States of America, could adversely affect the financial and economic environment in Brazil, which could have a material
adverse effect on us.

***Summary of Risks Relating to the Brazilian Financial Services Industry and Our Business***

&nbsp;&nbsp;&nbsp;&nbsp;• The highly competitive environment in the Brazilian financial services market may adversely affect us,
including our business prospects.

&nbsp;&nbsp;&nbsp;&nbsp;• We may not be able to detect or prevent money laundering and other criminal activities fully or on a
timely basis, which could expose us to additional liability and could have a material adverse effect on us.

&nbsp;&nbsp;&nbsp;&nbsp;• Social and environmental risks may have a material adverse effect on us.

&nbsp;&nbsp;&nbsp;&nbsp;• In addition, climate change can create transition risks, physical risks and other risks that could adversely
affect us.

&nbsp;&nbsp;&nbsp;&nbsp;• We are subject to increasing scrutiny and regulation from data protection laws. Failure to protect personal
information could adversely affect us.

&nbsp;&nbsp;&nbsp;&nbsp;• We are exposed to risk of loss from legal and regulatory proceedings.

&nbsp;&nbsp;&nbsp;&nbsp;• Disclosure controls and procedures over financial and nonfinancial reporting may not prevent or detect
all errors or acts of fraud.

&nbsp;&nbsp;&nbsp;&nbsp;• Changes in taxes and other fiscal assessments may have a negative effect on us. Furthermore, we are
subject to review by tax authorities, and an incorrect interpretation by us of tax laws and regulations may have a material adverse effect
on us.

&nbsp;&nbsp;&nbsp;&nbsp;• Our loan and investment portfolios are subject to risk of prepayment, which could have a material adverse
effect on us.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• Furthermore, the credit quality of our loan portfolio may deteriorate and our loan loss reserves could
be insufficient to cover our loan losses, which could have a material adverse effect on us.

&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity and funding risks are inherent in our business, and since our main sources of funds are short-term
deposits, a sudden shortage of funds could cause an increase in costs of funding and an adverse effect on our revenues and our liquidity
levels.

&nbsp;&nbsp;&nbsp;&nbsp;• The value of the collateral securing our loans may decline and become insufficient, and we may be unable
to realize the full value of the collateral securing our loan portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;• We may face significant challenges in possessing and realizing value from collateral with respect to
loans in default.

&nbsp;&nbsp;&nbsp;&nbsp;• Failure to successfully implement and continue to improve our risk management policies, procedures and
methods, including our credit risk management system, could materially and adversely affect us, and we may be exposed to unidentified
or unanticipated risks.

&nbsp;&nbsp;&nbsp;&nbsp;• Failure to adequately protect ourselves against risks relating to cybersecurity could materially and
adversely affect us.

&nbsp;&nbsp;&nbsp;&nbsp;• Our business is highly dependent on the proper functioning of information technology systems. We are
also subject to increasing scrutiny and regulation governing cybersecurity risks.

&nbsp;&nbsp;&nbsp;&nbsp;• We utilize artificial intelligence, which could expose us to liability or adversely affect our business.

&nbsp;&nbsp;&nbsp;&nbsp;• We are subject to counterparty risk in our business.

&nbsp;&nbsp;&nbsp;&nbsp;• Our financial results are constantly exposed to market risk. We are subject to fluctuations in interest
rates and other market variables, which may materially and adversely affect us.

&nbsp;&nbsp;&nbsp;&nbsp;• We engage in transactions with related parties that others may not consider to be on an arm's-length
basis.

&nbsp;&nbsp;&nbsp;&nbsp;• The outbreak of public health emergencies could materially and adversely impact our business, financial
condition, liquidity and results of operations.

***Summary of Risks Relating to Our Controlling Shareholder, Our Units and American Depositary Receipts (ADRs)***

&nbsp;&nbsp;&nbsp;&nbsp;• Our ultimate controlling shareholder has a great deal of influence over our business and its interests
could conflict with ours.

&nbsp;&nbsp;&nbsp;&nbsp;• Our status as a controlled company and a foreign private issuer exempts us from certain of the corporate
governance standards of the NYSE, limiting the protections afforded to investors. Furthermore, our corporate disclosure may differ from
disclosure regularly published by issuers of securities in other countries, including the United States.

&nbsp;&nbsp;&nbsp;&nbsp;• The liquidity and market prices of the units and the ADRs may be adversely affected by the cancellation
of units or substantial sale of units and shares in the market, or by the relative volatility and limited liquidity of the Brazilian securities
markets.

&nbsp;&nbsp;&nbsp;&nbsp;• The relative volatility and limited liquidity of the Brazilian securities markets may negatively affect
the liquidity and market prices of the units and the ADRs.

&nbsp;&nbsp;&nbsp;&nbsp;• Holders of our units and our ADRs may not receive any dividends or interest on stockholders' equity.
They may also be unable to exercise preemptive rights with respect to our units underlying the ADRs and find it difficult to exercise
voting rights at our shareholders' meetings.

&nbsp;&nbsp;&nbsp;&nbsp;• Investors may find it difficult to enforce civil liabilities against us or our directors or officers.
In addition, judgments of Brazilian courts with respect to our units or ADRs will be payable only in *reais*.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• Holders of ADRs could be subject to Brazilian income tax on capital gains from sales of ADRs. Furthermore,
if you exchange your ADRs for their underlying units, you risk losing Brazilian tax advantages and the ability to remit foreign currency
abroad.

**Risks Relating to Brazil and Macroeconomic and Political Conditions in Brazil and Globally**

***The Brazilian government has exercised significant influence over the Brazilian economy. The Brazilian government's macroeconomic management strategies, new rules as well as political and economic conditions, could adversely affect us and the trading price of our securities.***

We and the trading price of our securities may be adversely affected by changes in policy, laws or regulations at the federal, state and municipal levels involving or affecting factors such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• currency volatility;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inflation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reserve requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• capital requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liquidity of capital and lending markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• nonperforming loans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax policies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the regulatory framework governing our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exchange rate controls and restrictions on remittances abroad; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other political, social and economic developments in or affecting Brazil.

In the past, the Brazilian government has intervened in the economy and has on occasion made significant changes in policy and regulations, including, among others, changes in regulations, price controls, capital controls, changes in the exchange rate regime, and limitations on imports, which have affected Brazilian asset prices. Recently, the Brazilian government and the Brazilian Congress have adopted important measures, such as changes in tax policies, and constraints that have affected and could affect the price of our securities.

Uncertainty over whether the Brazilian government will continue to implement changes in policy or regulation and over which of the proposed changes will be implemented creates instability in the Brazilian economy, increasing the volatility of the Brazilian securities markets, which may have an adverse effect on us and our securities. As a result, the prices of Brazilian financial assets have experienced a high level of volatility in 2024 and in 2025 through the date of this annual report. We cannot guarantee you that Brazilian financial markets will not experience significant volatility going forward. Economic and political developments in Brazil may also affect the business of the Brazilian financial industry.

We are not able to fully estimate the impact of global and Brazilian political and macroeconomic developments and economic regulatory policy changes on our business and lending activity, nor are we able to predict how current or future measures implemented by regulatory policymakers may impact our business. Although the incumbent administration has presented its priority initiatives for 2026, there is a considerable level of uncertainty regarding future economic measures that may be implemented and how they could affect the economy or our business or financial performance, including as a result of the Brazilian presidential and other elections to be held in October 2026. Any changes in regulatory capital requirements for lending, reserve requirements, or product and service regulations, among others, may materially adversely affect our business.

*[**Table of Contents**](#toc)*<br>

***The political environment in Brazil may adversely affect Brazil's economy and investment levels and have a material adverse effect on us.***

Brazil's political environment has historically influenced, and continues to influence, the performance of the country's economy by affecting investor and consumer confidence. Periods of political uncertainty have been associated with slower economic activity and increased volatility in the securities of Brazilian issuers.

As mentioned, there are uncertainties regarding the policies to be followed by the incumbent government, the ability of this administration to continue implementing policies and reforms, as well as the external perception of the Brazilian economy and political environment, all of which could have a negative impact on our business and the price of our securities.

Furthermore, expenditures by the Brazilian federal government have historically led to fiscal deficits at the federal level, resulting in seven straight years of deficits between 2014 and 2020. However, the Brazilian federal government recorded a budget surplus in 2022, due in part to rising commodity prices and higher inflation. In 2023, as commodity prices stabilized, inflation receded and cyclical activities slowed down, government revenue also decreased, while expenditures continued to rise, resulting in a budget deficit. In 2024, although total fiscal revenues at the federal level increased 9.6% as compared to 2023 (in inflation-adjusted terms) as a result of ad hoc measures approved in the end of 2023, public expenditures continued to rise at a faster pace, and Brazil registered another budget deficit in the period. In 2025, the Brazilian government continued to face a challenging fiscal environment despite the approval of a new fiscal framework in 2023. Similarly, the governments of Brazil's constituent states are grappling with fiscal challenges due to high debt burdens, declining revenues, and inflexible expenditures, extensive federal economic relief programs, and aid efforts to address the impacts of the early 2024 floods in Rio Grande do Sul. As Brazil approaches presidential and other elections scheduled for October 2026, uncertainty regarding the outcome of the elections and future economic and regulatory policies may further increase volatility in the market price of securities issued by Brazilian companies, including our securities, which may adversely affect our business.

The uncertainties regarding the implementation of the Brazilian government's agenda, considering the scenario for 2026 (implementation of the tax reform on consumption, assessment of changes to income tax rules, the relationship between the executive, legislative, and judiciary branches, interactions among leading political parties and the incumbent administration's approval rating) and changes related to monetary, fiscal, and social security policies could affect the Brazilian economy. Any such developments may contribute to economic instability in Brazil and increase the volatility of securities issued by Brazilian companies, including our securities.

***Inflation, government efforts to control inflation, and changes in interest rates may hinder the growth of the Brazilian economy and could have an adverse effect on us.***

Inflation, government measures to curb inflation, and speculation related to possible measures regarding inflation may significantly contribute to uncertainty regarding the Brazilian economy and weaken investors' confidence in Brazil. In particular, inflation adversely affects our personnel and other administrative expenses that are directly or indirectly tied to inflation indexes, such as the IPCA, and the IGP-M.

For example, considering the amounts in 2025, each additional percentage point change in the IPCA rate would impact our personnel and other administrative expenses by approximately R$116 million and R$88 million, respectively.

Inflation for the years ended December 31, 2025, 2024 and 2023, as measured by the IPCA, was 4.3%, 4.8%, and 4.6%, respectively. Increased inflation in the year ended December 31, 2023, resulted mainly from temporary supply shocks affecting the prices of foodstuffs. These inflationary pressures were compounded by additional factors, including events that hit electricity generation and led to an increase in energy prices, disruptions in supply chains, the depreciation of the *real*, the ongoing war between Ukraine and Russia, the war in the Middle East, and the COVID-19 pandemic (particularly in China), among others. The IPCA showed a declining trend in the beginning of 2024 in year-over-year terms, but adverse climatic conditions affecting energy and food prices, combined with the depreciation of the *real* and strong economic activity with a low unemployment rate, fueled renewed inflationary pressures. These factors contributed to inflation ending the year at 4.8%, above the upper limit set by the Brazilian Central Bank pursuant to applicable law. Inflation decelerated to 4.3% in 2025, reflecting a combination of monetary policy tightening and the gradual dissipation of prior supply-side shocks, although services inflation and exchange-rate volatility continued to exert upward pressure on consumer prices.

*[**Table of Contents**](#toc)*<br>

Moreover, the measures to fight inflation, mainly carried out by the Brazilian Central Bank, have had significant effects on the Brazilian economy and our business, and could continue to do so. As a result of inflationary pressures that arose in Brazil in early 2021 and intensified globally throughout 2022, the Brazilian Central Bank began tightening its monetary policy, raising the SELIC rate starting in mid-March 2021, ultimately reaching 9.25% by the end of 2021. This cycle continued into 2022, with the SELIC rate peaking at 13.75% in August 2022, at which point the Brazilian Central Bank opted to maintain that level. The SELIC rate stayed at 13.75% for nearly a year, as inflation hovered near the upper limit of the Brazilian Central Bank's target range pursuant to applicable law (3.25% for 2023 and 3.0% thereafter). In August 2023, as inflationary pressures eased, the Brazilian Central Bank began reducing the SELIC rate, which fell to 10.50% by May 2024. Nevertheless, renewed inflationary pressures—driven in part by fiscal concerns stemming from persistent budget deficits and increased government spending—prompted the Brazilian Central Bank to reverse course and resume hiking rates in September 2024, with the SELIC rate reaching 15.00% in mid-2025. As of the date of this annual report, the SELIC rate stands at 15.00% per annum, reflecting the challenges of controlling inflation amid a strong economy, historically low unemployment levels, and fiscal imbalances requiring tighter monetary policy to maintain economic stability.

Our income, expenses, assets and liabilities are impacted by interest rates levels and volatility. Therefore, our results of operations and financial condition are affected by inflation, interest rate fluctuations and monetary policies. Changes in these variables may materially and adversely affect the growth of the Brazilian economy, our loan portfolios, our cost of funding and our income from credit operations. For more information about our risk management, see "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Credit Risk." Any changes in interest rates may negatively impact our business, financial condition and results of operations. In addition, increases in base interest rates may adversely affect us by reducing the demand for our credit and investment products, increasing funding costs, and increasing the risk of default by our customers in the short run.

Moreover, tight monetary policies with high compulsory reserve requirements may restrict Brazil's growth and the availability of credit, reduce our loan volumes and increase our loan loss provisions. Conversely, interest rate decreases may trigger increases in inflation and, consequently, growth volatility and the need for sudden and significant interest rate increases, which could negatively affect our spreads.

***Exposure to Brazilian federal government debt could have a material adverse effect on us.***

We invest in Brazilian federal government bonds. As of December 31, 2025, 14.3% of our total assets, and 65.2% of our securities portfolio, consisted of debt securities issued by the Brazilian federal government. Any failure by the Brazilian government to make timely payments under the terms of these securities, or a significant decrease in their market value, will have a material adverse effect on us.

***Fluctuations in interest rates and other factors may affect our obligations under legacy employee pension funds.***

We sponsor defined benefit pension plans and a healthcare plan for former and current employees, most of which were inherited from legacy plans and/or the acquisition of other banks (though we discontinued the use of defined benefit pension plans for our employees in 2005). In order to determine our current obligations, we use actuarial methods and assumptions that are inherently uncertain and involve the exercise of significant judgment, including with respect to interest rates, which are one of the most important variables used in determining our current pension obligations.

Changes in the present value of our obligations under our legacy defined benefit pension plans could require us to increase contributions, which would divert resources from use in other areas of our business. Any such increase may be due to factors over which we have no or limited control. Increases in our pension liabilities and obligations could have a material adverse effect on our business, financial condition and results of operations.

Decreases in interest rates can increase the present value of obligations under our legacy defined benefit pension plans and lifetime medical assistance plan. Increases in interest rates have the opposite effect.

As of December 31, 2025 our obligations for pension funds and similar liabilities totaled R$1.4 billion (out of total provisions for legal and administrative proceedings, commitments, pensions and other matters of R$11.8 billion). For additional information, see note 21 to our audited consolidated financial statements included in this annual report.

***Exchange rate volatility may have a material adverse effect on the Brazilian economy and on us.***

The Brazilian currency has experienced frequent and substantial variations in relation to the U.S. dollar and other foreign currencies. The Brazilian government has used various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system.

Although long-term depreciation of the real is generally linked to the rate of inflation in Brazil, depreciation of the real occurring over shorter periods of time has resulted in significant variations in the exchange rate among the real, the U.S. dollar and other currencies. As a result of fluctuations in commodity prices, international developments and periods of progress and setbacks on the domestic front—such as during the presidential impeachment process in 2016, or the approval of the national pension system reform in 2019—the real has weakened over the last few years. In 2023, the volatility in the R$/U.S.$ exchange rate persisted as it ranged from R$4.7202 to R$5.4459 per U.S.$1.00 as a result of geopolitical issues, increases in interest rate and economic uncertainties abroad combined with uncertainty regarding Brazil's fiscal and budgetary position. As a result, the exchange rate was R$4.8413 per U.S.$1.00 on December 31, 2023. In 2024, the real experienced a significant devaluation against the U.S. dollar, influenced in part by the outcome of the U.S. general election, which was expected to result in a stronger U.S. dollar relative to other currencies, as well as concerns surrounding the Brazilian economy and the Brazilian federal government's fiscal situation. The exchange rate was R$6.1923 per U.S.$1.00 on December 31, 2024. In 2025, there was significant volatility in the R$/U.S.$ exchange rate, which fluctuated within a wide band that ranged from R$5.2729 to R$6.2086 per U.S. $1.00 as a result of ongoing economic and political uncertainty both globally and within Brazil. As of December 31, 2025 the exchange rate was R$5.5024 per U.S.$1.00. There can be no assurance that the *real* will not substantially depreciate or appreciate further against the U.S. dollar.

In the year ended December 31, 2025, a variation of 1.0% in the exchange rate of *reais* to U.S. dollars would have resulted in a negative variation of income on our net foreign exchange position denominated in U.S. dollars of R$2.4 million.

Past episodes of depreciation of the *real* relative to the U.S. dollar created additional inflationary pressures in Brazil, which led to increases in interest rates and limited Brazilian companies' access to foreign financial markets and prompted the adoption of recessionary policies by the Brazilian government. Depreciation of the *real* may also, in the context of an economic slowdown, lead to decreased consumer spending, deflationary pressures and reduced growth of the Brazilian economy as a whole, and thereby harm our asset base, financial condition and results of operations. Additionally, depreciation of the *real* could make our foreign-currency-linked obligations and funding more expensive, negatively affect the market price of our securities portfolios, and have similar consequences for our borrowers. Conversely, appreciation of the *real* relative to the U.S. dollar and other foreign currencies could lead to a deterioration of the Brazilian balance of payments, as well as hinder export-driven growth. Depending on the circumstances, either a depreciation or appreciation of the *real* could materially and adversely affect the growth of the Brazilian economy and our business, financial condition and results of operations.

***Infrastructure, workforce deficiency and other factors in Brazil may impact economic growth and have a material adverse effect on us.***

Our performance depends on the overall health and growth of the Brazilian economy. Brazilian GDP growth has fluctuated over the past few years. In 2023, GDP growth reached 3.0%, driven in particular by strong agricultural output, including a record grain harvest. In 2024, Brazilian GDP grew 3.4%, supported by resilient domestic demand and historically low unemployment levels, while market forecasts as of the date of this annual report generally project more moderate GDP growth for 2025 (around 2.2%) as the effects of tighter monetary policy, reduced fiscal impulse, and a less favorable global environment are expected to weigh on economic activity. The growth and performance of the Brazilian economy may be impacted by other factors such as nationwide strikes, natural disasters, pandemics or other disruptive events. Any of these factors could lead to labor market volatility and generally impact income, purchasing power and consumption levels, which could limit growth, increase delinquency rates and ultimately have a material adverse effect on us.

***Developments and the perception of risk in other countries may adversely affect the Brazilian economy and market price of Brazilian issuers' securities.***

The market value of securities of Brazilian issuers is affected by economic and market conditions in other countries, including the United States, European countries (including Spain, where Santander Spain, our controlling shareholder, is based), and other Latin American and emerging market countries. Although economic conditions in Europe and in the United States may differ significantly from economic conditions in Brazil, investors' reactions to developments in these countries may have an adverse effect on the market value of securities of Brazilian issuers.

Investors' perceptions of the risks associated with our securities may also be affected by allegations of fraud, accounting misstatements, corruption, bribery or other matters involving other Brazilian issuers. Investors' perceptions of the risks associated with our securities may also be affected by perception of risk conditions in Spain. Additionally, crises in other emerging market countries may reduce investor interest in securities of Brazilian issuers, including our securities. This could adversely affect the market price of our securities, restrict our access to capital markets and compromise our ability to finance our operations in the future on favorable terms, or at all.

In 2020 and 2021, the fallout of the COVID-19 pandemic significantly affected the performance of Brazilian markets, an effect that was less pronounced in 2022 in Brazil. These factors persisted in 2022 and have been compounded by the war between Russia and Ukraine, which has contributed to inflationary pressures worldwide and spurred central banks to increase interest rates, thereby spurring fears of a global economic slowdown. Continued COVID-19 outbreaks in China in 2022 and early 2023 and the response of the Chinese government to these outbreaks adversely affected the Chinese economy. During 2023 and 2024, the Chinese government resumed introducing monetary and fiscal stimuli in order to reverse that setback and meet its economic growth goals. The global economy was also adversely affected by the war in the Middle East, which started in October 2023 and has been ongoing since then. In addition, inflationary pressures in advanced economies proved to be more resilient than previously imagined, thus leading monetary authorities in these economies to extend their monetary tightening cycle and renewing fears of a global recession, which weighed on the market value of our securities. In response to the monetary tightening cycles launched in advanced economies and the extension of a subdued economic growth in China, global inflationary pressures started abating and opened room for the monetary authorities around the world to start reducing their base interest rates (e.g., the European Central Bank in June 2024 and the U.S. Federal Reserve in September 2024), which translated into favorable prospects for a recovery in the world economic growth in the near future. However, these developments may not necessarily be felt in Brazil, where inflationary pressures have persisted, and the Brazilian Central Bank has continued to raise interest rates in response to fiscal concerns and other domestic challenges. In 2025, inflation continued to run above the Brazilian Central Bank's target range and monetary policy remained tight as authorities sought to contain price pressures amid moderating GDP growth. See "—Inflation, government efforts to control inflation, and changes in interest rates may hinder the growth of the Brazilian economy and could have an adverse effect on us."

In addition, we continue to be exposed to disruptions and volatility in the global financial markets due to their effects on the financial and economic environment, particularly in Brazil, which could include a slowdown in the economy, an increase in the unemployment rate, a decrease in the purchasing power of consumers and a lack of credit availability. We lend primarily to Brazilian borrowers, and these effects could materially and adversely affect our customers and increase our nonperforming loans, resulting in increased risk associated with our lending activity and requiring us to make corresponding revisions to our risk management and loan loss reserve models.

***A global economic downturn could have a material adverse effect on us.***

The global macroeconomic environment is facing challenges, including the ongoing war between Russia and Ukraine, the war in the Middle East, supply chain disruptions, high energy prices, resilient inflationary pressures, trade disruptions and an economic slowdown in China. Although most central banks around the world have started reducing their base interest rates, there is considerable uncertainty over the lagged effects of the prior tight monetary policies adopted by the central banks and financial authorities of some of the world's leading economies, including the United States, which may result in GDP contractions across major economies in the short and medium term.

In 2022, the war between Russia and Ukraine contributed to further increases in the prices of energy, oil and other commodities and to volatility in financial markets globally, as well as a new landscape in relation to international sanctions. There have also been concerns over conflicts, unrest and terrorist threats in the Middle East, Europe and Africa, which have resulted in volatility in oil and other markets. The United States and China are involved in controversies related to trade barriers in China that have threatened a trade war between the countries, which have implemented or proposed to implement tariffs on certain imported products. Sustained tensions between the United States and China could significantly undermine the stability of the global economy. This risk was heightened by the outcome of the U.S. presidential election in November 2024, with the new administration taking a more protectionist stance on trade, including the reimplementation or escalation of tariffs on Chinese goods, as well as measures aimed at reducing U.S. reliance on Chinese supply chains.

On October 7, 2023, Hamas launched an attack on Israel targeting Israeli civilians. In response, Israel declared war against Hamas, attacking Hamas targets in Gaza and the region. In 2024, in response to attacks from Lebanon and Iran, Israel attacked Lebanon targeting Hezbollah infrastructure and leaders and carried out airstrikes against Iranian military sites. In June 2025, the ongoing conflict between Israel and Iran escalated following a resolution adopted by the Board of Governors of the International Atomic Energy Agency, which found that Iran had not been in compliance with its nuclear non-proliferation obligations. Subsequently, the two nations exchanged missile and drone strikes, and according to public reporting, the US carried out attacks on Iranian nuclear facilities with the stated intent of preventing Iran from developing a nuclear weapon. Press reporting suggests these strikes caused substantial but not decisive damage, likely delaying Iran's enrichment activities by months to a few years. A ceasefire agreement brokered by international mediators and signed in late 2025 has reduced hostilities between Israel, Iran, and Iran-aligned groups in Lebanon and Gaza, including Hamas and Hezbollah. While the ceasefire has halted large-scale military operations, its implementation is still uncertain, and geopolitical tensions continue to pose risks of renewed instability. Uncertainties around the sustainability of peace, reconstruction efforts, sanctions relief, and regional realignments could continue to affect energy markets, trade flows, and investor sentiment, potentially causing volatility in oil and gas prices, supply chain disruptions, inflationary pressures, and market uncertainty, among other potential consequences.

Scenarios of political tensions and instability throughout the world stemming from a variety of factors such as heightened polarization and political interference, fragmentation and scandals, may lead to shifting and unpredictable outcomes in political elections, legislative and policy-making efforts, social conditions, government stability and the global economy and to a progressive erosion of the rule of law in certain long-standing democracies. Furthermore, increasing public debt levels together with high interest costs may not be sustainable and could lead certain countries to face higher sovereign risk premia and sovereign debt crises. A deterioration of the global economic, political, social and financial environment, particularly in Europe and the Americas, could have a material adverse impact on the financial sector, affecting our operating results, financial position and prospects.

In particular, the risk of a return in Europe to a fragile and volatile environment, heightened political tensions or recession could be aggravated if, among others, (i) the German economy falls into recession due to reduced industrial competitiveness, (ii) European Union policies to increase defense spending, rearm Europe and support Ukraine prove unsuccessful, (iii) reforms to improve labor markets, productivity and competitiveness fail, (iv) the banking union and other measures of European integration do not progress, or (v) anti-European groups become more widespread. A deterioration of the economic and financial environment in Europe could have a material adverse impact on the global economy, affecting our operating results, financial position and prospects.

In addition, growing protectionism and trade tensions could intensify and negatively impact the economies of the countries where we operate. The U.S. presidential administration has increased tariffs, and the possibility for new or higher trade tariffs remains. Certain U.S. trading partners have announced retaliatory actions, including tariffs, in response. The continuation, pause or escalation of tariffs and other trade restrictions, the continued depreciation of the U.S. dollar and other non-trade-related measures or policies of the U.S. presidential administration, including immigration reforms, foreign interventions and military actions, could further transform international trade relations, investment flows and supply chains significantly, resulting in continued market volatility and lower global growth, intensifying concerns over the global macroeconomic environment, inflation and the potential for a recession. Any of the foregoing could have a material adverse effect on our business, results of operations, financial condition and prospects.

*[**Table of Contents**](#toc)*<br>

Moreover, the shift in the global economy's center of gravity from the Atlantic to the Pacific and, in particular, China's increasing relevance as a key trading partner and source of financing for Latin American economies, could negatively impact U.S. and European banks, particularly those like Santander Spain with limited presence in Asia, reducing Santander Spain's global market share and customer base and affecting our business, operating results, financial condition and prospects. An uncertain outlook for China, including weak economic growth and related policy actions, and tensions or conflicts involving China, Taiwan or the United States, could negatively affect the world economy and impact our operating results, financial condition, and prospects.

Additionally, the United Kingdom ceased to be a member of the European Union in 2020. A limited trade deal was agreed between the United Kingdom and the European Union with the relevant new regulations coming into force on January 1, 2021. The trade deal, however, did not include agreements on certain areas such as financial services and data adequacy. Uncertainty remains around the terms of the UK's relationship with the European Union and the lack of a fully comprehensive trade agreement may negatively impact the economic growth of both regions. Similarly, an adverse effect on the United Kingdom and the European Union may have an adverse effect on the wider global economy or market conditions and investor confidence. This could, in turn, have a material adverse effect on our operations, financial condition and prospects and/or the market value of our securities.

Any material changes in the economy and the global capital market, including Brazil, may decrease the interest of investors in Brazilian assets, including our ADRs, which may adversely affect the market price of our securities, in addition to making it difficult for us to access the capital markets and finance our operations, including on acceptable terms.

Any slowdown or instability in the global economy could impact income, purchasing power and consumption levels in Brazil, among other things, which could limit growth, increase delinquency rates and ultimately have a material adverse effect on us while also creating a more volatile economy, limiting potential access to capital and liquidity. In addition, any global economic slowdown or uncertainty may result in volatile conditions in the global financial markets, which could have a material adverse effect on us, including on our ability to access capital and liquidity on acceptable financial terms, if at all. Any such adverse effect on capital markets funding availability or costs or in deposit rates could have a material adverse effect on our interest margins and liquidity.

***Disruption or volatility in global financial and credit markets, including as a result of the ongoing war between Russia and Ukraine and uncertainties following the ceasefire agreement in the Middle East, could adversely affect the financial and economic environment in Brazil, which could have a material adverse effect on us.***

Volatility and uncertainty in global financial and credit markets have generally led to a decrease in liquidity and an increase in the cost of funding for Brazilian and international issuers and borrowers. Such conditions may adversely affect our ability to access capital and liquidity on financial terms acceptable to us, if at all.

Part of our funding originates from repurchase agreements which are generally short term and volatile in terms of volume, as they are directly impacted by market liquidity. As these transactions are typically guaranteed by Brazilian government securities, the value and/or perception of value of the securities may significantly impact the availability of funds, as the cost of funding will increase if the quality of the Brazilian government securities used as collateral is adversely affected as a result of conditions in financial and credit markets, making this source of funding inefficient for us.

If the size and/or liquidity of the Brazilian government bond and/or repurchase agreement markets decrease, if there is increased collateral credit risk or if we are unable to access capital and liquidity on financial terms acceptable to us or at all, our financial condition and the results of our operations may be adversely affected.

***Geopolitical conflicts and related uncertainties, such as the continuance or escalation of the war in Ukraine and the uncertainties following the ceasefire agreement in the Middle East, could materially affect our financial position and increase our operational risk.***

On February 24, 2022, Russia launched a large-scale military action against Ukraine. The war in Ukraine has caused an ongoing humanitarian crisis in Europe as well as volatility in financial markets globally, heightened inflation, shortages and increases in the prices of energy, oil, gas and other commodities. In response to the war in Ukraine, several countries, including the United States, the European Union member states, the United Kingdom and other UN member states, have imposed severe sanctions on Russia and Belarus. In addition, the sanctions imposed also include a ban on trading in sovereign debt and other securities. The war has exacerbated supply chain problems, particularly for those businesses most sensitive to rising energy prices. The war has led to, and continues to lead to, further increases in energy prices, supply chain problems and inflationary pressures. These factors contribute to an environment of higher interest rates, market volatility and a slowdown in the global economy.

*[**Table of Contents**](#toc)*<br>

The scale of sanctions is unprecedented, complex and rapidly evolving, and poses continuously increasing operational risk to us. Our corporate framework and policies are designed to ensure compliance with applicable laws, regulations and economic sanctions in the countries in which we operate, including U.S., European Union, United Kingdom and United Nations economic sanctions. We cannot predict whether Brazil or any of the jurisdictions whose sanctions frameworks we adhere to will enact additional economic sanctions or trade restrictions in response to the war in Ukraine or to other current or future geopolitical conflicts or tensions. While we do not knowingly engage in direct or indirect dealings with sanctioned parties according to applicable sanctions, or in direct dealings with the sanctioned countries/territories, we may on occasion have indirect dealings within the sanctioned countries/territories, but aim to operate in line with applicable U.S., European Union, United Kingdom and United Nations blocking and sectoral sanctions regulations. The Santander Group is committed to the ongoing enhancement of sanctions governance, list management and screening controls. However, evolving measures may increase the complexity of compliance and residual risk, including the risk of penalties if banks deal with blocked persons, even indirectly, or facilitate significant transactions involving Russia's military industry.

A ceasefire agreement brokered by international mediators and signed in late 2025 has reduced hostilities between Israel, Iran and Iran-aligned groups in Lebanon and Gaza, including Hamas and Hezbollah. While the ceasefire has halted large-scale military operations, its implementation is still uncertain. Geopolitical tensions continue to pose risks of renewed instability, which could affect other regions and, in turn, continue to affect energy markets, trade flows, and investor sentiment. This could cause volatility in oil and gas prices, supply chain disruptions, inflationary pressures, and market uncertainty, among other potential consequences.

Furthermore, we believe that the risk of cyberattacks on companies and institutions has increased and could increase further as a result of the aforementioned conflicts and in response to the sanctions imposed, which could adversely affect our ability to maintain or enhance our cybersecurity and data protection measures. Although we actively monitor for cyberattacks, there can be no assurance that our cybersecurity and data protection measures and defenses will be effective at identifying, preventing, mitigating or remediating any such cyberattacks.

We do not have a physical presence in Russia or Ukraine and our physical presence in the Middle East is very limited. Further, our direct exposure to Russian, Ukrainian or Middle Eastern markets is not material. However, the ability of certain of our customers to fulfill their obligations has been negatively impacted, particularly those with greater exposure to the Russian, Ukrainian or Middle Eastern markets. The impact of ongoing or increased geopolitical tensions and sanctions on global markets, macroeconomic conditions globally, and other potential future geopolitical developments remains uncertain and may exacerbate our operational risk. As a result, our businesses, results of operations and financial position could be adversely affected by any of these factors directly or indirectly arising from the war in Ukraine or from uncertainties following the ceasefire agreement in the Middle East or from other geopolitical conflicts or tensions.

***Ongoing or future investigations relating to corruption, diversion of public funds, money laundering fraud and other matters that are being conducted by the Brazilian federal police as well as other Brazilian and non-Brazilian regulators and law enforcement officials may adversely affect the growth of the Brazilian economy and could have a material adverse effect on us.***

Certain Brazilian companies have faced and continue to face investigations and prosecutions by the CVM, the U.S. Securities and Exchange Commission, or the "SEC," the U.S. Department of Justice, the Brazilian Federal Police and the Brazilian Federal Prosecutor's Office, the Comptroller General of Brazil, and other relevant governmental authorities, in connection with corruption, money laundering and other allegations of wrongdoing. Anticorruption or other investigations may lead to significant reputational harm, which may affect the investigated corporations' images and revenues and result in downgrades from rating agencies or funding restrictions, among other negative effects. Allegations of bribery, corruption, fraud, money laundering improper accounting practices or other similar matters among certain large Brazilian companies may also adversely affect investors' perceptions of the risks involved in investing in Brazilian companies and result in volatility in financial markets. Given the significance of the companies that historically have been subject to investigations in the Brazilian economy, the investigations and their fallout have had and may continue to have an adverse effect on Brazil's economic growth prospects in the short to medium term.

Furthermore, the negative effects on such companies and others may also impact the level of investments in infrastructure in Brazil, which may lead to lower economic growth or contraction in the near to medium term. Although we have reduced our exposure to companies involved in government investigations, we cannot assure that new investigations will not be launched or that additional persons will not become subject to investigation. To the extent that the repayment ability of these companies is hampered by any fines and/or other sanctions that may be imposed upon them or reputational or commercial damage as a result of investigations, we may also be materially adversely affected. In addition, investigations have involved members of the Brazilian executive and legislative branches, which caused considerable political tensions, and, as a result, persistently poor economic conditions in Brazil could have a material adverse effect on us. It is difficult to calculate the size and extension of the effects derived from such political tensions, which may further deteriorate Brazil's economic conditions.

**Risks Relating to the Brazilian Financial Services Industry and Our Business**

***Our growth, asset quality and profitability, among others, may be adversely affected by a slowdown in Brazil and volatile macroeconomic and political conditions.***

A slowdown or recession in Brazil and other major world economies could lead major financial institutions, including some of the world's largest global commercial banks, investment banks, mortgage lenders, mortgage guarantors and insurance companies, to experience significant difficulties, including runs on deposits, the need for government aid or assistance or the need to reduce or cease providing funding to borrowers (including to other financial institutions). The year 2021 was marked by an accelerated recovery in the level of activity in the main global economies, as a result of the expansionary monetary and fiscal policy, including reductions in interest rates. As a result, inflation rates in 2021 and 2022 have increased considerably in Brazil and globally, due to the strong increase in aggregate demand and bottlenecks in supply and production chains due to shortages of inputs. In 2023, inflation in Brazil was moderate compared to the levels observed at the end of 2022, reflecting tighter monetary policy, a stronger Brazilian real, and favorable supply-side factors, including a record grain harvest. However, the path toward achieving the 3.0% inflation target set by the Brazilian Central Bank under applicable law proved uncertain. This became evident in 2024, as inflationary pressures resurfaced, driven by a combination of adverse climatic conditions impacting energy and food prices, a significant depreciation of the real against the U.S. dollar—partly due to the outcome of the U.S. presidential election—and persistent fiscal concerns in Brazil, which compounded domestic economic challenges. In 2025, inflation remained above the Brazilian Central Bank's target range and economic activity showed signs of slowing, leading the Brazilian Central Bank to maintain a restrictive monetary policy stance amid heightened uncertainty regarding the domestic fiscal outlook and a less supportive global environment.

In Brazil, the generalized increase in prices was exacerbated by the depreciation of the real against the U.S. dollar and other major currencies, leading the Brazilian Central Bank to raise the SELIC rate from 2.0% at the end of 2020 to 13.75% at the end of 2022. The SELIC rate remained at this high level until August 2023, when the decrease in inflationary pressures and a more favorable economic outlook allowed the Brazilian Central Bank to begin loosening monetary policy. The SELIC rate at the end of 2023 stood at 11.75%. Rate cuts continued into 2024, with the SELIC rate reaching 10.50% in May 2024. However, renewed inflationary pressures in the second half of 2024—driven by adverse weather conditions, a significant devaluation of the real amid the global strength of the U.S. dollar following the U.S. presidential election, and Brazil's persistent fiscal challenges—led the Brazilian Central Bank to reverse course, initiating a tightening cycle in September 2024. After sustained increases through 2024 and into 2025, the Brazilian Central Bank continued its tightening cycle, with the SELIC rate reaching 15.00% in mid-2025 and remaining at that near-two-decade high as of the date of this annual report, reflecting ongoing efforts to contain inflation amid persistent price pressures and a challenging macroeconomic backdrop.

Volatile conditions in financial markets could also have a material adverse effect on us, including on our ability to access capital and liquidity on acceptable financial terms, if at all. If capital markets financing becomes unavailable or excessively expensive, we may be forced to raise the rates we pay on deposits to attract more customers and may be unable to maintain certain liability maturities. Any such adverse impact in capital markets funding availability or costs or in deposit rates could have a material adverse effect on our interest margins and liquidity.

In particular, we face, among others, the following risks related to economic downturns and volatile conditions:

&nbsp;&nbsp;&nbsp;&nbsp;• a reduction in demand for our products and services;

&nbsp;&nbsp;&nbsp;&nbsp;• increased inflationary pressure, continued high unemployment and continued reductions in growth prospects
could make the economic environment more unpredictable and adversely affect our results of operations;

&nbsp;&nbsp;&nbsp;&nbsp;• polarization of the political scenario in Brazil amid the process of submission of key legislation to
the Brazilian Congress' approval. In addition, the run-up to the 2026 general elections could result in negotiations to form new
political alliances that may result in a more complex political scenario;

&nbsp;&nbsp;&nbsp;&nbsp;• government action in regulation (including banking regulation with respect to the Agenda BC#, such as
regulations on social and environmental risks and prudential corporate capital, or CSLL, IOF and other tax reform), technological disruptions
(including as a result of PIX and Open Finance) and the entry of new players (including large technology companies, fintech and marketplaces)
have made and may continue to make our industry more competitive and potentially less profitable;

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• an increase of, or changes in, the regulation of our industry and compliance with such regulation would
likely continue to increase our costs and may affect the pricing for our products and services, increase our regulatory risks and limit
our ability to pursue business opportunities; and

&nbsp;&nbsp;&nbsp;&nbsp;• an inability of our borrowers to comply with their existing obligations on a timely basis, whether in
part or at all. Macroeconomic shocks may adversely affect the income of our retail and corporate customers and may adversely affect the
recoverability of our loans, resulting in increased loan losses.

Any of the developments mentioned above may have a material adverse effect on our business, financial condition and results of operations, including without limitation as a result of a higher cost of capital and limitations on the availability of funding given the market's requirement for a higher risk premium due to market conditions, expectations for the sector and availability of liquidity in the Brazilian and global economy.

Each of these factors could also affect the credit quality of our counterparties, due to the slowdown in the Brazilian economy as a whole and reduction in purchasing power and operating margins. The process we use to estimate losses inherent in our credit exposure requires complex judgments, including forecasts of economic conditions and how these economic conditions might impair the ability of our borrowers to repay their loans. The degree of uncertainty concerning economic conditions may adversely affect the accuracy of our estimates, which may, in turn, impact the reliability of the process and the sufficiency of our loan loss allowances.

***The value and liquidity of the portfolio of investment securities that we hold may be adversely affected by the level of economic activity in Brazil.***

The recoverability of our loan portfolios, our capacity to increase lending, and our overall results of operations and financial condition depend significantly on the level of economic activity in Brazil. The quality of our loan portfolio may deteriorate as a result of these risks and our loan loss reserves could be insufficient to cover our loan losses, which could have a material adverse effect on us. See "—The credit quality of our loan portfolio may deteriorate and our loan loss reserves could be insufficient to cover our loan losses, which could have a material adverse effect on us."

In addition, we are exposed to sovereign debt in Brazil. Our net exposure to Brazilian sovereign debt as of December 31, 2025 was R$182.2 billion (or 14.3% of our total assets as of that date) and consisted principally of National Treasury Bills (LTN), Treasury Bills (LFT) and National Treasury Notes (NTN-A, NTN-B, NTN-C and NTN-F). Recessionary conditions in Brazil would likely have a significant adverse impact on our loan portfolio and sovereign debt holdings and, as a result, on our financial condition, cash flows and results of operations.

The recoverability of our loan portfolios and our ability to increase the amount of loans outstanding and our results of operations and financial condition in general, are dependent to a significant extent on the level of economic activity in Brazil. See "—The credit quality of our loan portfolio may deteriorate and our loan loss reserves could be insufficient to cover our loan losses, which could have a material adverse effect on us."

Our revenues are also subject to deterioration due to unfavorable political and diplomatic developments, social instability, trade and travel restrictions, international conflicts, and changes in governmental policies, including expropriation, nationalization, international ownership legislation, sanctions and trade restrictions, interest rate caps and fiscal and monetary policies.

The economy of Brazil faces long-standing structural challenges, including weaknesses in infrastructure, competitiveness and education, high levels of social inequality, rising inflation and increasing public debt levels and have experienced significant volatility in recent decades. This volatility resulted in fluctuations in deposits and in lending. In addition, Brazil is affected by commodities price fluctuations, which in turn may affect financial market conditions through exchange rate fluctuations, interest rate volatility and deposits volatility. Furthermore, fiscal and monetary policy measures enacted by the Brazilian government in response to the COVID-19 pandemic significantly increased governmental debt through 2021 and 2022. In 2023, 2024 and 2025, despite economic growth and positive developments from a revenue standpoint, the level of governmental debt (as a percentage of the GDP) has continued to increase.

Among the risks that could negatively affect the Brazilian economy and financial markets and lead to a slowdown of the global economy, recession, inflationary pressures and/or stagflation are: (i) the depreciation of the U.S. dollar against other currencies that could lead to a widespread loss of confidence in the U.S. dollar; (ii) the continuance or escalation of the war in Ukraine and uncertainties following the ceasefire agreement in the Middle East; (iii) heightened geopolitical instability arising from recent developments in Venezuela, which may increase volatility in financial markets and global energy prices; (iv) other increases in the prices of energy and other commodities; (v) the breakdown of global supply chains; and (vi) the return to tighter monetary and fiscal policies, including higher interest costs. Negative and fluctuating economic conditions, such as slowing or negative growth and a changing interest rate environment, could impact our profitability by causing lending margins to decrease and credit quality to decline and leading to decreased demand for higher margin products and services.

*[**Table of Contents**](#toc)*<br>

***The strong competitive environment in the Brazilian financial services market may adversely affect us, including our business prospects.***

The Brazilian financial markets, including the banking, insurance and asset management sectors, are highly competitive, with this competition increasing in recent years. We face significant competition in all of our main areas of operation from other Brazilian and international banks, as well as state-owned institutions, including through portability of loans. In particular, we face the challenge of competing in an ecosystem where the relationship with the consumer is based on access to digital data and interactions. This access is increasingly dominated by digital platforms, which are already eroding our results in very relevant markets such as payments. This privileged access to data can be used as leverage to compete with us in other adjacent markets and may reduce our operations and margins in core businesses such as lending or wealth management. This could be accelerated by the advent of open banking and open finance, which could result in our competitors gaining access to valuable data regarding our customers which may help them compete with us. In addition, the alliances that our competitors are starting to build with large technology firms can make it more difficult for us to successfully compete with them and could adversely affect us.

Moreover, nontraditional providers of banking services, such as e-commerce providers, mobile telephone companies and internet search engines, as well as payment services for blockchain technologies, may offer and/or increase their offerings of financial products and services directly to customers. These nontraditional providers of banking services currently have an advantage over traditional providers because they are not subject to banking regulation. Several of these competitors may have long operating histories, large customer bases, strong brand recognition, and significant financial and marketing capabilities as well as other resources. They may adopt more aggressive prices and rates and devote more resources to technology, infrastructure and marketing. These new competitors, in addition to neobanks, have entered and may continue to enter the market or existing competitors may adjust their services with unique product or service offerings or approaches to providing banking services. If we are unable to successfully compete with current and new competitors, or if we are unable to anticipate and adapt our offerings to changing banking industry trends, including technological changes, our business may be adversely affected.

In addition, our failure to effectively anticipate or adapt to emerging technologies or changes in customer behavior, including among younger customers, could delay or prevent our access to new digital-based markets, which would in turn have an adverse effect on our competitive position and business. Furthermore, the widespread adoption of new technologies, including distributed ledger technology, AI, quantum computing and/or biometrics, to provide services such as digital currencies, cryptocurrencies and payments, could require substantial expenditures to modify or adapt our existing products and services as we continue to grow our internet and mobile banking capabilities. Our customers may choose to conduct business or offer products in areas that may be considered speculative or risky. Further growth of such new technologies and mobile banking platforms could negatively impact the value of our investments in bank premises, equipment and personnel for our branch network. The persistence or acceleration of this shift in demand toward internet and mobile banking may necessitate changes to our retail distribution strategy. Our failure to implement changes to our distribution strategy swiftly and effectively could have an adverse effect on our competitive position.

In addition, on November 16, 2020, the Brazilian Central Bank instituted PIX, as well as the Instant Payment System (*Sistema de Pagamentos Instantâneos*), or "SPI," which enables participants to settle electronic transfers of funds in real time and is available for 24 hours a day, seven days a week, and every day in the year. This ecosystem promotes innovation of the existing payment infrastructure. Although the regulations relating to the PIX ecosystem are subject to further developments from time to time, such initiatives may promote greater competition in the industry, and could cause customers to move away from the solutions we offer towards PIX solutions. In particular, PIX has made processing payments faster and less expensive, has fostered and is expected to continue to foster additional competition and allow new entrants to join the market, while also serving as a significant source of data that will contribute to the ongoing transformation of the financial industry in Brazil. Such developments could therefore materially and adversely affect our business and results of operations.

Increasing competition could also require that we increase the rates offered on our deposits or lower the rates we charge on loans, which could also have a material adverse effect on our profitability, as well as limit our ability to increase our customer base and expand our operations, further increasing competition for investment opportunities.

*[**Table of Contents**](#toc)*<br>

The success of our operations, our profitability and our ability to maintain our competitive position depends, in part, on the success of new products and services we offer our customers and our ability to offer products and services that meet the customers' needs during their entire life cycle. However, we may not be able to manage emerging risks as we develop new products and services, which could have a material adverse effect on us. Moreover, our customers' needs and/or desires may change over time, and such changes may render our products and services obsolete, outdated or unattractive and we may not be able to develop new products that meet our customers' changing needs and/or desires. Our success is also dependent on our ability to anticipate and leverage new and existing technologies that may have an impact on products and services in the banking industry. Technological changes may further intensify and complicate the competitive landscape and influence customer behavior. If we cannot respond in a timely fashion to the changing needs and/or desires of our customers, including as a result of an aging population, we may lose existing or prospective customers, which could in turn materially and adversely affect us. In addition, the cost of developing and maintaining innovative products is likely to affect our results of operations.

We face the challenge of simplifying the range of our products and services and, at the same time, being able to satisfy the needs of our clients by offering new products and services. The development of these new products and services exposes us to new and potentially increasingly complex risks, such as conduct risk in our relationships with customers, and increased development expenses. Our employees and risk management systems, as well as our experience and that of our partners, may not be adequate to enable us to properly manage such risks. Any or all of these factors, individually or collectively, could have a material adverse effect on us.

Should our customer service levels ever be perceived by the market to be materially below those of our competitor

financial institutions, we could lose existing and potential new business. If we are not successful in retaining and strengthening customer relationships, we may lose market share, incur losses on some or all of our activities or fail to attract new deposits or retain existing deposits. Additionally, reputational or operational incidents associated with new products could affect customer trust and brand perception, amplifying competitive pressures. Any of the conditions described above could have a material adverse effect on our operating results, financial condition and prospects.

***We are subject to extensive regulation and regulatory and governmental oversight, which could adversely affect our business, operations and financial condition.***

The Brazilian financial markets are subject to extensive and continuous regulatory control by the Brazilian government, principally by the Brazilian Central Bank, the CVM and the CMN, which, in each case, materially affects our business. We have no control over the issuance of new regulations that may affect our operations, including in respect of:

&nbsp;&nbsp;&nbsp;&nbsp;• minimum capital requirements;

&nbsp;&nbsp;&nbsp;&nbsp;• reserve and compulsory deposit requirements;

&nbsp;&nbsp;&nbsp;&nbsp;• limits on investments in fixed assets;

&nbsp;&nbsp;&nbsp;&nbsp;• lending limits and other credit restrictions, including compulsory allocations;

&nbsp;&nbsp;&nbsp;&nbsp;• limits and other restrictions on interest rates and fees;

&nbsp;&nbsp;&nbsp;&nbsp;• limits on the amount of interest banks can charge or the period for capitalizing interest; and

&nbsp;&nbsp;&nbsp;&nbsp;• accounting and statistical requirements.

The regulations governing Brazilian financial institutions are continuously evolving, and the Brazilian Central Bank has reacted actively and extensively to developments in our industry.

Changes in regulations in Brazil and international markets may expose us to increased compliance costs and limit our ability to pursue certain business opportunities and provide certain products and services. Brazilian regulators are constantly updating prudential standards in accordance with the recommendations of the Basel Committee on Banking Supervision, in particular with respect to capital and liquidity, which could impose additional significant regulatory burdens on us. For example, future liquidity standards could require us to maintain a greater proportion of our assets in highly liquid but lower-yielding financial instruments, which would negatively affect our net interest margin. There can be no assurance that future changes in regulations or in their interpretation or application will not have a material adverse effect on us.

*[**Table of Contents**](#toc)*<br>

As some of the banking laws and regulations have been recently issued or become effective, the manner in which those laws and related regulations are applied to the operations of financial institutions is continuously evolving. Moreover, to the extent that these recently adopted regulations are implemented inconsistently in Brazil, we may face higher compliance costs. The measures of the Brazilian Central Bank and the amendment of existing laws and regulations, or the adoption of new laws or regulations, could adversely affect our ability to provide loans, make investments or render certain financial services. No assurance can be given generally that laws or regulations will be adopted, enforced or interpreted in a manner that will not have a material adverse effect on our business and results of operations. Furthermore, regulatory authorities have substantial discretion in how to regulate banks, and this discretion, and the regulatory mechanisms available to the regulators, have been increasing during recent years. Regulations may be unexpectedly and immediately imposed by governments and regulators in response to a crisis, and these may especially affect financial institutions such as those that may be deemed to be systemically important. In addition, the volume, granularity, frequency and scale of regulatory and other reporting requirements require a clear data strategy to enable consistent data aggregation, reporting and management. Inadequate management information systems or processes, including those relating to risk data aggregation and risk reporting, could lead to a failure to meet regulatory reporting requirements or other internal or external information demands, and we may face supervisory measures as a result.

We may also be subject to potential impacts relating to regulatory changes affecting our controlling shareholder, Santander Spain, due to continued significant financial regulatory reform in jurisdictions outside Brazil that directly or indirectly affect Santander Spain's businesses, including Spain, the European Union, the United States and other jurisdictions. In Spain and in other countries in which Santander Spain's subsidiaries operate (including Brazil), there is continuing political, competitive and regulatory scrutiny of the banking industry. Political involvement in the regulatory process, in the behavior and governance of the banking sector and in the major financial institutions in which the local governments have a direct financial interest, and in their products and services and the prices and other terms applied to them, is likely to continue. Changes to current legislation and its implementation through regulation (including additional capital, leverage, funding, liquidity and tax requirements), policies (including fiscal and monetary policies established by central banks and financial regulators, and changes to global trade policies), and other legal and regulatory actions may impose additional regulatory burdens on Santander Group, including Santander Brasil, in these jurisdictions. In the European Union, these reforms could include changes relating to capital requirements, liquidity and funding, or other measures, implemented as a result of the unification of the European banking system under a European Banking Union. In the United States, financial regulatory statutes and rules are continually under review by the U.S. Congress and U.S. financial regulatory agencies. Changes in key personnel at the U.S. financial regulatory agencies may result in differing interpretations of existing rules and guidelines and potentially more stringent enforcement and more severe penalties than previously. For more information, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—U.S. Financial Regulatory Reform." We cannot predict the outcome of any financial regulatory reforms in the European Banking Union, the United States or other jurisdictions, and we cannot yet determine their effects on Santander Spain and, consequently, their effects on us, but regulatory changes may result in additional costs for us.

***We are subject to potential intervention by any of our regulators or supervisors.***

Our business and operations are subject to increasingly significant rules and regulations set by the Brazilian Central Bank, the CVM, the PREVIC, the SUSEP, the CNSP and the CMN, with which we are required to comply to conduct our banking and financial services business. These apply to business operations, affect our financial returns, and include reserve and reporting requirements and conduct-of-business regulations.

In their supervisory roles, the Brazilian Central Bank and the CMN seek to maintain the safety and soundness of financial institutions with the aim of strengthening the protection of customers and the financial system. Their continuing supervision of financial institutions is conducted through a variety of regulatory tools, including the collection of information by way of prudential returns, reports obtained from skilled persons, visits to firms and regular meetings with management to discuss issues such as performance, risk management and strategy. As a result, we face high levels of supervisory scrutiny (resulting in increasing internal compliance costs and supervision fees), and in the event of a breach of our regulatory obligations we are likely to face more stringent regulatory fines.

*[**Table of Contents**](#toc)*<br>

***We are subject to regulation on a consolidated basis and may be subject to liquidation or intervention on a consolidated basis.***

We operate in a number of credit- and financial services-related sectors through entities under our control. For certain purposes related to regulation and supervision, the Brazilian Central Bank treats us and our subsidiaries and affiliates as a single financial institution. While we believe that our consolidated capital base provides financial strength and flexibility to our subsidiaries and affiliates, their individual activities could indirectly put our capital base at risk. Any investigation or intervention by the Brazilian Central Bank, particularly in the activities carried out by any of our subsidiaries and affiliates, could have a material adverse impact on our other subsidiaries and affiliates and, ultimately, on us. If we or any of our financial subsidiaries become insolvent, the Brazilian Central Bank may carry out an intervention or liquidation process on a consolidated basis rather than conduct such procedures for each individual entity. In the event of an intervention or a liquidation process on a consolidated basis, our creditors would have claims to our assets and the assets of our consolidated financial subsidiaries. In this case, claims of creditors of the same nature held against us and our consolidated financial subsidiaries would rank equally in respect of payment. If the Brazilian Central Bank carries out a liquidation or intervention process with respect to us or any of our financial subsidiaries on an individual basis, our creditors would not have a direct claim on the assets of such financial subsidiaries, and the creditors of such financial subsidiaries would have priority in relation to our creditors in connection with such financial subsidiaries' assets. The Brazilian Central Bank also has the authority to carry out other corporate reorganizations or transfers of control under an intervention or liquidation process.

***Increases in reserve, compulsory deposit and minimum capital requirements may have a material adverse effect on us.***

Compulsory deposit requirements in Brazil require banks to hold part of funding received from customers with the Brazilian Central Bank, which sets these requirements as a means of controlling liquidity in the financial markets and preserving the solvency of financial institutions. The Brazilian Central Bank has periodically changed the level of reserves and compulsory deposits that financial institutions in Brazil are required to maintain, as well as determined compulsory allocation requirements to finance government programs. These changes are a continuing source of risk, as new or an increase in existing reserve and compulsory deposit or allocation requirements, may adversely affect our liquidity and our ability to fund our loan portfolio and other investments and, as a result, may have a material adverse effect on us.

Compulsory deposits and allocations generally do not yield the same return as other investments and deposits because a portion of compulsory deposits and allocations do not bear interest and must be used to finance government programs, including a federal housing program and rural sector subsidies.

In recent years, the CMN and Brazilian Central Bank published several rules to implement Basel III in Brazil. This new set of regulations covers the revised definition of capital, capital requirements, capital buffers, credit valuation adjustments, exposures to central counterparties, leverage and liquidity coverage ratios, and treatment of systemically important financial institutions.

For more information on the rules implementing Basel III, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Capital Adequacy and Leverage – Basel—Basel III" and "Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Liquidity and Funding—Capital Management."

***We may not be able to detect or prevent money laundering and other criminal activities fully or on a timely basis, which could expose us to additional liability and could have a material adverse effect on us.***

We are required to comply with applicable anti-money laundering and anti-terrorism, or "AML/CFT," antibribery and corruption, sanctions and other laws and regulations (collectively, financial crime and compliance ("FCC") regulations) applicable to us. These laws and regulations require us, among other things, to conduct full customer due diligence (including sanctions and politically exposed person screening) and keep our customer, account and transaction information up to date. We have FCC policies and procedures in place detailing what is required from those responsible. We are also required to conduct FCC training for our employees and to report suspicious transactions and activity to appropriate law enforcement following full investigation by our special incidents area.

Financial crime continues to be the subject of enhanced regulatory scrutiny and supervision by regulators globally. AML/CFT, antibribery, anticorruption and sanctions laws and regulations are increasingly complex and detailed. Key standard-setting and regulatory bodies continue to provide guidelines to strengthen the interaction and cooperation between prudential and AML/CFT supervisors. Compliance with these laws and regulations requires automated systems, sophisticated monitoring and skilled compliance personnel.

We maintain updated policies and procedures aimed at detecting and preventing the use of our banking network for money laundering and other financial crime-related activities. However, emerging technologies, such as cryptocurrencies (which were recently regulated by statute in Brazil) and innovative payment methods, could limit our ability to track the movement of funds and, therefore, present a risk to us. Our ability to comply with the legal requirements depends on our ability to improve detection and reporting capabilities and reduce variation in control processes and oversight accountability. These require implementation and embedding within our business effective controls and monitoring, which in turn requires ongoing changes to systems and operational activities. Financial crime is continually evolving and is subject to increasingly stringent regulatory oversight and focus. This requires proactive and adaptable responses from us so that we are able to deter threats and criminality effectively. Even known threats can never be fully eliminated, and there have been, and may in the future continue to be, instances where we may be used by other parties to engage in money laundering and other illegal or improper activities.

*[**Table of Contents**](#toc)*<br>

In addition, we rely heavily on our employees to assist us by spotting such activities and reporting them, and our employees have varying degrees of experience in recognizing criminal tactics and understanding the level of sophistication of criminal organizations. Where we outsource any of our customer due diligence, customer screening or anti-financial crime operations, we remain responsible and accountable for full compliance and any breaches. While we expect relevant counterparties to maintain and apply their own appropriate compliance measures, procedures and internal policies, such measures may not be completely effective in preventing third parties from using our (and our relevant counterparties') services as a conduit for illicit purposes (including illegal cash transactions) without our (or our relevant counterparties') knowledge. If we are unable to apply the necessary scrutiny and oversight of third parties to whom we outsource certain tasks and processes, there remains a risk of regulatory breach, and if we are associated with, or even accused of being associated with, breaches of AML/CFT, antibribery and corruption or sanctions requirements, our reputation could suffer and/or we could become subject to fines, sanctions and/or legal enforcement (including being added to "watch lists" that would prohibit certain parties from engaging in transactions with us), any one of which could have a material adverse effect on our operating results, financial condition and prospects.

We have been, and may in the future be, subject to negative coverage in the media about us or our clients, including with respect to alleged conduct such as failure to detect and/or prevent any financial crime activities or comply with FCC regulations. Negative media coverage of this type about us, whether it has merit or not, could materially and adversely affect our reputation and perception among current and potential clients, investors, vendors, partners, regulators and other third parties, which in turn could have a material adverse effect on our operating results, financial condition and prospects as well as damage our customers' and investors' confidence and the market price of our securities.

The reputational damage to our business and global brand could be severe if we were found to have breached AML/CFT, antibribery, anticorruption or sanctions requirements. Our reputation could also suffer if we are unable to protect our customers' data and bank products and services from being accessed or used for illegal or improper purposes. If we are unable to comply fully with applicable laws, regulations and expectations, our regulators and relevant law enforcement agencies have the ability and authority to impose significant fines and other penalties on us, including requiring a complete review of our business systems, day-to-day supervision by external consultants and ultimately the revocation of licenses.

Additionally, we are required by Brazilian Central Bank regulations, which derive from resolutions from the UN Security Council, to comply with certain rules relating to the local enforcement of sanctions imposed by the UN Security Council. We believe we already have the control and compliance procedures in place to satisfy such additional compliance requirements. However, we continue to evaluate their impact on our control and compliance procedures and whether adjustments will need to be made to our control and compliance procedures as a result.

***We are subject to increasing scrutiny and regulation from data protection laws, including penalties in the event of noncompliance with the terms and conditions of certain new European and Brazilian regulations.***

We receive, maintain, transmit, store and otherwise process proprietary, confidential, sensitive and personal data, including public and non-public personal data of our customers, employees, counterparties and other third parties, including, but not limited to, personally identifiable information, including personal financial information. The collection, sharing, use, retention, disclosure, protection, transfer and other processing of this data is governed by stringent federal, state, local and foreign laws, rules, regulations and standards, and the legal and regulatory framework for privacy, data protection and cybersecurity is in considerable flux and evolving rapidly. As privacy, data protection and cybersecurity risks for banking organizations and the broader financial system have significantly increased in recent years, privacy, data protection and cybersecurity issues have become the subject of increasing legislative and regulatory focus. There has also been increasing regulatory scrutiny from the SEC with respect to adequately disclosing risks concerning cybersecurity and data privacy, which increases the risk of investigations into cybersecurity practices and related disclosures, of companies within its jurisdiction which, at a minimum, can result in distraction of management and diversion of resources for targeted businesses.

*[**Table of Contents**](#toc)*<br>

We are subject to regulations enacted by Brazilian authorities, which include the LGPD and data protection regulations issued by the Brazilian Data Protection Agency, or the "ANPD." The LGPD came into effect in September 2020, with the exception of its articles 52, 53 and 54, which came into effect on August 1, 2021. The LGPD sets out several penalties, which include warnings, blocking and erasure of data, public disclosure of the offense, and fines of up to 2% of the economic group's turnover in Brazil in the preceding year, capped at R$50 million per offense. In addition, we are subject to Regulation (EU) 2016/279 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (the "General Data Protection Regulation" or "GDPR"). Additionally, following the United Kingdom's withdrawal from the EU, we also are subject to the UK General Data Protection Regulation ("UK GDPR") (i.e., a version of the GDPR as implemented into United Kingdom law). The GDPR and UK GDPR have also imposed significant penalties and fines for noncompliance of up to the higher of 4% of annual worldwide turnover or €20 million (or £17.5 million under the UK GDPR), and, for other specified infringements, penalties and fines of up to the higher of 2% of annual worldwide turnover or €10 million (or £8.7 million under the UK GDPR). European data protection authorities have already imposed fines for GDPR violations up to, in some cases, hundreds of millions of euros.

Compliance with the LGPD, the GDPR, the UK GDPR and other data protection regimes, as well as adaptation to their respective updates, has required and may in the future require substantial adjustments to our procedures and policies. These changes could adversely impact our business by increasing our operational and compliance costs. Further, there is a risk that the measures may not be implemented correctly or that there may be partial noncompliance with the new procedures. If there are breaches of our privacy, data protection and cybersecurity obligations, as the case may be, we could face significant civil administrative and monetary sanctions, as well as reputational damage, which could have a material adverse effect on our operating results, financial condition and prospects. Furthermore, following any such breach, we may be ordered to change our business practices, policies or systems in a manner that adversely impacts our operating results.

For more information, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Data Protection Requirements."

***The implementation of the "ECA Digital" framework in Brazil may impose new obligations and restrictions that could increase our compliance costs, disrupt our operations and expose us to enforcement or litigation risks.***

Brazil has advanced initiatives to strengthen protections for children and adolescents online through Law No. 15,211 enacted on September 17, 2025, known as "ECA Digital," which will come into force in March 2026. As details are defined and implemented, ECA Digital may establish new duties for companies that offer products or services potentially accessed by children and adolescents, including governance, age-assurance, parental supervision, transparency, reporting and accountability measures.

Depending on the final contours of ECA Digital and its implementing regulations, we may be required to adapt product features, user interfaces, content and advertising practices, age-assurance and parental authorization workflows, complaint-handling and incident-reporting procedures, and governance for users identified as, or reasonably likely to be, children or adolescents. The framework may require us to deploy or integrate age-assurance technologies, enhance content moderation and curation controls for minors, implement parental management tools, limit profiling or targeted advertising to minors, and increase disclosures and auditability regarding our handling of minors' data and online interactions. It may also require technical and organizational controls demonstrably tailored to risks to children and adolescents.

Compliance with ECA Digital may necessitate material investment in technology, processes, and personnel; the redesign or removal of features, changes to our relationships with third-party providers; new contractual controls; and periodic audits. Some obligations could be ambiguous or evolve over time, creating uncertainty in implementation, and divergent guidance among authorities could require jurisdiction-specific adaptations across Brazil.

Actual or alleged noncompliance could lead to investigations, administrative proceedings, orders to modify or suspend features, fines or penalties, or mandatory corrective measures. We may also face civil claims, including consumer or collective actions, alleging violations of duties to protect children and adolescents online, as well as reputational harm arising from public scrutiny of our practices. Even good-faith efforts to comply may be challenged as insufficient or inconsistent with evolving expectations, and requirements may apply retroactively or be interpreted broadly.

If ECA Digital is interpreted or applied in a manner inconsistent with our current practices, or if we are unable to timely implement measures deemed adequate to protect children and adolescents online, we could incur increased compliance costs, operational disruptions, product or feature limitations, loss of users or partners, regulatory scrutiny, fines or penalties, litigation, and reputational damage, any of which could adversely affect our business, financial condition and results of operations.

***Uncertainties arising from the liquidation of Banco Master and increased demands on the Brazilian deposit-insurance system (Fundo Garantidor de Créditos - FGC) could adversely affect financial institutions***

In November 2025, the Brazilian Central Bank ordered the extrajudicial liquidation of Banco Master, following an administrative proceeding related to serious violations of financial regulations, liquidity issues and an ongoing criminal investigation involving alleged fraud schemes related to credit instruments. As a result, thousands of creditors became eligible for reimbursement through the Brazilian deposit-insurance system (*Fundo Garantidor de Créditos*) ("FGC"), representing one of the largest claims ever made on the FGC. Additional strain on the FGC may arise from related institutions, including Will Financeira (Will Bank), which was liquidated in January 2026 and may also require further FGC payouts.

The scale of these payouts has prompted market discussions, including us, regarding potential changes to FGC coverage rules and contribution requirements applicable to financial institutions. These discussions include proposals to reduce coverage limits or impose higher contribution rates on institutions with riskier asset profiles. Any such regulatory or policy changes could increase contribution and funding costs, reduce credit availability, or impose additional capital levels compliance burdens on financial institutions, which could materially and adversely affect our business, financial condition, and results of operations.

These developments may also increase perceptions of systemic risk and lead to higher costs or reduced liquidity in bank funding markets. If similar situations were to arise involving other financial institutions, or if the FGC's capacity to meet future obligations were impaired, the broader financial system could experience increased volatility. Such conditions could adversely affect the Brazilian economy, the stability of financial markets, and the operating and funding costs of financial institutions, including ours.

***We utilize artificial intelligence, which could expose us to liability or adversely affect our business.***

We utilize, and continue to explore additional uses of, artificial intelligence, or AI, in connection with our business, products and services, including AI designed to enhance transaction monitoring and sanctions screening, improve customer experience and reduce operational risk. However, regulation of AI is rapidly evolving worldwide as legislators and regulators are increasingly focused on these powerful emerging technologies. The technologies underlying AI and its uses are subject to a variety of laws and regulations, including intellectual property, privacy, data protection, cybersecurity, consumer protection, competition, and equal opportunity laws, and are expected to be subject to increased regulation and new laws or new applications of existing laws and regulations. AI is the subject of ongoing review by various governmental and regulatory agencies around the world, and various jurisdictions are applying, or are considering applying, their platform moderation, cybersecurity and data protection laws and regulations to AI or are considering legal frameworks for AI. In particular, multiple jurisdictions have adopted or are considering AI-specific requirements, and U.S. federal and state agencies are assessing how existing laws apply to AI. Supervisory guidance in some jurisdictions also addresses AI-related privacy, data protection and cybersecurity and third-party risk management.

In Brazil, AI regulation was approved by the Brazilian Senate in 2024 by means of the Bill of Law No. 2,338/23, which seeks to establish general national standards for the development, implementation, and responsible use of AI systems in Brazil. This bill, which is currently under discussion in the Brazilian House of Representatives and, if approved, will be submitted for presidential approval or veto, would seek to introduce potential compliance requirements, liability standards, or usage restrictions that could directly affect our operations. If approved by the Brazilian House of Representatives, by the Federal Senate and thereafter enacted into law, Bill of Law No. 2,338/23 may impose additional compliance burdens, establish liability frameworks, or mandate specific transparency and accountability measures for our use of AI systems.

We may not be able to anticipate how to respond to these rapidly evolving laws and regulations, and we may need to expend resources to adjust our offerings in certain jurisdictions if the legal and regulatory frameworks are inconsistent across jurisdictions. Furthermore, because AI technology itself is highly complex and rapidly developing, it is not possible to predict all of the legal or regulatory risks that may arise relating to the use of AI. If laws and regulations relating to AI are implemented, interpreted or applied in a manner inconsistent with our current practices or policies, such laws and regulations may adversely affect our use of AI and our ability to provide and to improve our services, require additional compliance measures and changes to our operations and processes or result in increased compliance costs and potential increases in civil claims against us, any of which could adversely affect our operating results, financial condition and prospects.

*[**Table of Contents**](#toc)*<br>

Moreover, there are significant risks involved in utilizing AI and no assurance can be provided that our use will enhance our products or services or produce the intended results. For example, AI models may be flawed, trained on insufficient or poor-quality data, reflect unwanted forms of bias or contain other errors or inadequacies, any of which may not be easily detectable. AI solutions (including those supplied by third parties) may produce false, inaccurate, misleading, biased or otherwise deficient inferences or outputs, rely on data, technology or intellectual property to which we or any of our contractors, vendors or service providers lack rights, or be subject to new documentation, transparency, governance and validation expectations. Strengthening controls to address these risks—such as human oversight, testing, independent model validation and preparing public and internal documentation—may increase costs and affect time-to-market, and any errors or inadequacies in AI systems used for control functions (such as transaction monitoring or sanctions screening) could lead to operational disruptions, compliance failures, regulatory scrutiny, reputational harm, fines or penalties. AI may subject us to new or heightened legal, regulatory, ethical, operational, reputational or other challenges; AI may involve inappropriate or controversial data practices by developers and end-users, or other factors adversely affecting public opinion of AI, any of which could impair the acceptance of AI solutions, including those incorporated into our products and services. We also depend on third-party models, datasets and infrastructure; outages, changes in functionality or terms, or concentration in a limited number of providers could disrupt our operations or increase costs.

If the AI solutions that we create or use are deficient, inaccurate or controversial, we could incur operational inefficiencies, competitive harm, legal liability, brand or reputational harm, or other adverse impacts on our business and financial results. There can be no assurance that our use of AI will be successful in reducing our operational risk or increasing our operational efficiencies or otherwise result in our intended outcomes.

Additionally, the use of AI solutions by companies has resulted in and may continue to result in cyberattacks, data breaches, data losses and other security incidents that implicate the proprietary, confidential, sensitive and personal data of AI users. For example, if any of our employees, contractors, vendors, service providers or other third parties with which we do business use any third-party AI-powered solutions in connection with our business, it may lead to the inadvertent disclosure or incorporation of our proprietary, confidential, sensitive or personal data into third-party systems or publicly available or third-party training sets (including so-called "data leakage") which may impact our ability to realize the benefit of our intellectual property or proprietary, confidential, sensitive or personal data, harming our competitive position and business. If we do not have sufficient rights to use the data or other material or content on which our AI solutions or other AI tools we use rely, we also may incur liability through the violation of applicable laws and regulations, third-party intellectual property, privacy or other rights, or contracts to which we are a party (including third-party claims of intellectual property infringement, misappropriation or other violation, has security vulnerabilities or other misuse of data, content or technology, regulatory enforcement actions and contractual remedies). Further, the use of AI solutions within products or services that we use or that are used by our contractors, vendors, service providers or other third parties with which we do business may pose similar risks, and we have limited ability to control the manner in which third-party products are developed or maintained or the manner in which third-party services are provided.

***We are exposed to risk of loss from legal and regulatory proceedings.***

We face risk of loss from legal and regulatory proceedings, including tax proceedings that could subject us to monetary judgments, fines and penalties. The current regulatory and tax enforcement environment in Brazil reflects an increased supervisory focus on enforcement. Combined with uncertainty about the evolution of the regulatory regime, this may lead to material operational and compliance costs.

We are from time to time subject to regulatory investigations and civil and tax claims and party to certain legal proceedings incidental to the normal course of our business, including in connection with conflicts of interest, lending activities, relationships with our employees, economic plans, and other commercial, privacy, data protection, cybersecurity, tax or climate-related matters. In view of the inherent difficulty of predicting the outcome of legal matters, particularly where the claimants seek very large or indeterminate damages, or where the cases present novel legal theories, involve a large number of parties, are in the early stages of investigation or discovery, or have common elements but require

assessment of circumstances on a case-by-case basis, we cannot state with certainty what the eventual outcome of these pending matters will be. The amount of our reserves in respect to these matters, which is calculated based on the probability of loss of each claim, is substantially less than the total amount of the claims asserted against us, and, in light of the uncertainties involved in such claims and proceedings, there is no assurance that the ultimate resolution of these matters will not significantly exceed the reserves currently accrued by us. As a result, the outcome of a highly uncertain matter may become material to our operating results.

As of December 31, 2025, we had provisions for judicial and administrative proceedings, commitments and other provisions of R$10,447 million (compared to R$9,612 million as of December 31, 2024). For more information, see note 22 to our audited consolidated financial statements included in this annual report and in "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings."

***We may face operational difficulties under the Brazilian instant payment scheme.***

As a direct participant of the PIX, we may face operational issues, as well as difficulties in adapting to the requirements established by the PIX payment scheme regulations and by the other applicable rules, mainly related to the minimum level of service to be provided on a recurring basis to customers, as well as recent new security and fraud prevention requirements set forth by the Brazilian Central Bank. The Brazilian Central Bank has also set a limited amount of R$1,000 for PIX transactions carried out between 8:00 p.m. (or, at the user's discretion, between 10:00 p.m.) and 6:00 a.m. As a result, we may be the target of administrative sanctions and/or judicial claims, either by the Brazilian Central Bank itself or as a result of complaints brought by our customers if we fail to adequately comply with this rule. Furthermore, as a consequence of potential administrative sanctions or judicial claims, we may face difficulties in retaining customers in relation to Santander SX, our solution for our customers to access PIX, which may have a material adverse effect on our financial results, as well as our reputation.

In addition, the Brazilian Central Bank has already issued in 2025 (as a result of high-profile frauds involving the PIX scheme and its participants and infrastructure providers) and may issue in the future new and stricter rules applicable to PIX participants, including new operational capacity requirements. The imposition by the Brazilian Central Bank of new requirements may adversely affect our operations. For more information related to the PIX and the SPI, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Brazilian Payment and Settlement System."

***Disclosure controls and procedures over financial and nonfinancial reporting may not prevent or detect all errors or acts of fraud.***

Disclosure controls and procedures, including internal controls over financial and nonfinancial reporting, (including any climate-related reporting), are designed to provide reasonable assurance that information required to be disclosed by us in reports filed or submitted under the U.S. Securities Exchange Act of 1934, as amended, or the "Exchange Act," is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission's rules and forms.

These disclosure controls and procedures have inherent limitations, which include the possibility that judgments in decision-making can be faulty and result in errors or mistakes. Additionally, controls can be circumvented by any unauthorized override of the controls. Consequently, our businesses are exposed to risk from potential non-compliance with policies, employee misconduct or negligence and fraud, as well as from deficiencies or delays in the preparation or submission of our financial or regulatory reports, which could result in regulatory sanctions, civil claims, increased regulatory scrutiny or reputational or financial harm. In recent years, a number of multinational financial institutions have suffered material losses due to the actions of "rogue traders" or other employees. It is not always possible to deter employee error or misconduct, and the precautions we take to prevent and detect this activity may not always be effective. Accordingly, because of the inherent limitations in our control systems, misstatements due to error or fraud may occur and not be detected.

***We are subject to review by tax authorities, and an incorrect interpretation by us of tax laws and regulations may have a material adverse effect on us.***

The preparation of our tax returns requires the use of estimates and interpretations of complex tax laws and regulations and is subject to review by tax authorities. We are subject to the income tax laws of Brazil. These tax laws are complex and subject to different interpretations by the taxpayer and relevant governmental tax authorities, leading to disputes, which are sometimes subject to prolonged evaluation periods until a final resolution is reached. In establishing a provision for income tax expense and filing returns, we must make judgments and interpretations about the application of these inherently complex tax laws. If the judgment, estimates and assumptions we use in preparing our tax returns are subsequently found to be incorrect, there could be a material adverse effect on us. The interpretations of Brazilian tax authorities are unpredictable and frequently involve litigation, which introduces further uncertainty and risk as to tax expense.

***Changes in taxes and other fiscal assessments may have a negative effect on us.***

The Brazilian government regularly enacts reforms to the tax and other assessment regimes to which we and our customers are subject. Such reforms include changes in tax rates and, occasionally, enactment of temporary levies, the proceeds of which are earmarked for designated governmental purposes. The effects of these changes and any other changes that result from enactment of additional tax reforms cannot be quantified and there can be no assurance that any such reforms would not have an adverse effect upon our business. Furthermore, such changes may produce uncertainty in the financial system, increasing the cost of borrowing and contributing to the increase in our nonperforming credit portfolio.

Changes in tax policy, including the creation of new taxes, may occur with relative frequency and such changes could have an adverse effect on our financial position or operating results. For example, the IOF rates have been frequently adjusted (both upwards and downwards) in recent years. Currently, since July 2025 the daily IOF tax rates applicable to local loans are approximately 0.0082% for individuals and for legal entities. We cannot estimate the impact that a change in tax laws or tax policy could have on our operations. For example, the IOF tax is a tool used by the Brazilian government to regulate economic activity, which does not directly impact our results of operations, though changes in the IOF tax can impact our business volumes generally.

In this context, on December 21, 2023, Constitutional Amendment No. 132/2023 (resulting from the approval of Proposed Constitutional Amendment (*Proposta de Emenda Constitucional*) No. 45/2019 by the Brazilian Congress) was published. This Constitutional Amendment initiated a tax reform in Brazil, reorganizing the framework for consumption taxes. Its main feature is the replacement of five taxes (PIS, COFINS, ICMS, ISS and IPI) with a unified value-added tax, divided into: (i) the Contribution on Goods and Services (*Contribuição sobre Bens e Serviços* – "CBS"), to fund the federal government; and (ii) the Tax on Goods and Services (*Imposto sobre Bens e Serviços* – "IBS"), to fund states and municipalities. On January 16, 2025, Complementary Law 214/2025 was published with the specific purpose of regulating the levy of the IBS and the CBS from 2026 onwards. However, the law did not include the applicable tax rates, which will be regulated through future laws to be published in due course.

With the enactment of Law No. 15,270, of November 26, 2025 ("Law 15,270/25"), as from January 2026, the payment, crediting, allocation or delivery of profits or dividends by the same legal entity to the same individual resident in Brazil, in a monthly amount exceeding R$50,000, becomes subject to withholding income tax ("WHT") at a 10% rate on the total amount paid, credited, allocated or delivered, without any deduction. Profits and dividends related to results accrued up to the year 2025 remain exempt from WHT, provided that (i) their distribution has been approved by December 31, 2025 and (ii) the payment, crediting, allocation or delivery occurs by 2028 and complies with the terms set forth in the relevant approval act adopted by December 31, 2025. Article 10 of Law No. 9,249/95 provides that profits or dividends paid, credited, delivered, allocated or remitted abroad are subject to WHT at a 10% rate.

Similarly to what is provided for individuals, the following situations are also exempt from WHT on the payment of dividends to nonresidents:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dividends related to results accrued up to the 2025 calendar year, provided that their distribution
has been approved by December 31, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dividends paid to foreign governments that grant reciprocity in relation to the Brazilian government,
as well as dividends paid to sovereign wealth funds; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dividends paid to foreign entities whose main activity is the administration of pension and retirement
benefit plans, pursuant to applicable regulations.

A tax credit shall be granted when the sum of the effective IRPJ and CSL rates of the distributing company, when added to the 10% WHT rate, results in taxation exceeding the applicable nominal rate. This credit shall be calculated on the amount of profits and dividends effectively subject to the 10% WHT. The nonresident recipient should be allowed to claim the credit within 360 days after the end of each fiscal year. Dividends paid by a Brazilian legal entity to another Brazilian legal entity are not subject to the tax on dividends.

Another recent relevant change in Brazilian tax legislation is Supplementary Law No. 224/2025 ("LC 224/25"), published on December 26, 2025, which established a new regime for the linear reduction of federal tax incentives and benefits, with the stated purpose of containing tax expenditures and restoring revenue levels. The rule was regulated by Decree No. 12,808/2025 and by Brazilian Federal Revenue Ruling No. 2,305/2025, which set out the technical application criteria, the calculation methodology and the timeline for its effectiveness.

*[**Table of Contents**](#toc)*<br>

The scope of LC 224/25 is defined both by objective criteria (taxes and benefits covered) and by express exceptions and limits arising from the constitutional and infra-constitutional system itself. The 10% linear reduction applies exclusively to the taxes expressly listed in paragraph 1 of Article 4 of LC 224/25, namely: PIS, COFINS, PIS-Import, COFINS-Import, IRPJ, CSL, Import Tax, IPI and Social Security Contribution. Taxes not listed—such as WHT, IRPF, IOF and CIDE—remain outside the scope of the rule. In addition, only those tax incentives and benefits are covered that are (i) identified in the tax expenditure statement attached to the 2026 Annual Budget Law ("2026 LOA") and/or (ii) expressly listed in LC 224/25 itself, which prevents the automatic application of the reduction to benefits that are not characterized as tax expenditures by the budget legislation or otherwise expressly mentioned in LC 224/25.

LC 224/25 also amended paragraph 2 of Article 9 of Law No. 9,249/1995, increasing the WHT rate levied on Interest on Net equity payments from 15% to 17.5%.

LC 224/25 adopted a hybrid reduction model, combining a general rule applicable to all tax expenditures listed in the 2026 LOA relating to the covered taxes, with a specific rule addressing certain regimes and benefits expressly identified in the statute, such as the presumed-profit regime, presumed IPI credits, presumed PIS/COFINS credits in specific agribusiness chains and zero-rate scenarios provided for in Law No. 10,925/2004. In all cases, the core rationale is the 10% reduction of the benefit, always measured against the so-called "standard system" of taxation.

Tax reforms or any change in laws and regulations affecting taxes or tax incentives may directly or indirectly adversely affect our business and our results of operations. The effects of these changes, if enacted, and any other changes that could result from the enactment of additional tax reforms, cannot be quantified.

***Our loan and investment portfolios are subject to risk of prepayment, which could have a material adverse effect on us.***

Our fixed-rate loan and investment portfolios are subject to prepayment risk, which results from the ability of a borrower or issuer to pay a debt obligation prior to maturity. Prepayments would also require us to amortize net premiums or commissions into income over a shorter period of time, thereby reducing the corresponding asset yield and net interest income. Prepayment risk may lead to an adverse impact on mortgages and other loans, since prepayments could shorten the weighted average life of these assets, which may result in a mismatch in our funding obligations and reinvestment at lower yields.

Prepayment risk is inherent to our commercial activity and could have a material adverse effect on our business, financial condition and results of operations. An increase in prepayments, in particular should the prevailing interest rates decrease from the rates in effect as of the date of this annual report, could have a material adverse effect on us.

***The credit quality of our loan portfolio may deteriorate and our loan loss reserves could be insufficient to cover our loan losses, which could have a material adverse effect on us.***

Risks arising from changes in credit quality and the recoverability of loans and amounts due from counterparties are inherent to a wide range of our businesses. Nonperforming or low credit quality loans can negatively impact our results of operations as the amount of our reported nonperforming loans may increase in the future as a result of growth in our total loan portfolio, including as a result of loan portfolios that we may acquire in the future (the credit quality of which may turn out to be worse than we had anticipated), or other factors, including factors beyond our control, such as adverse changes in the credit quality of our borrowers and counterparties or a general deterioration in economic conditions in Brazil and globally. In addition, the combined pressure of challenging macroeconomic conditions, high inflation and high interest rates may impact the ability of our customers to repay their debt. If we were unable to control the level of our credit impaired or poor credit quality loans, this could have a material adverse effect on us.

Our provisions for impairment losses are based on our current assessment, as well as expectations, concerning various factors affecting the quality of our loan portfolio. These factors include, among other things, our borrowers' financial condition, repayment abilities intentions, the realizable value of any collateral, the prospects for support from any guarantor, government macroeconomic policies, interest rates, and the legal and regulatory environment.

Since many of these factors are beyond our control and there is no infallible method for predicting loan and credit losses, there is no assurance that our current or future provisions for impairment losses will be sufficient to cover actual losses. If our assessment of and expectations concerning the above mentioned factors differ from actual developments, if the quality of our total loan portfolio deteriorates, for any reason, or if the future actual losses exceed our estimates of incurred losses, we may be required to increase our provisions for impairment losses, which may adversely affect us. If we were unable to control or reduce the level of our nonperforming or poor credit quality loans, this could have a material adverse effect on us.

*[**Table of Contents**](#toc)*<br>

As of December 31, 2025, our credit risk exposure (which includes gross loans and advances to customers, guarantees and private securities (securities issued by nongovernmental entities) amounted to R$778,881 million (compared to R$750,357 million as of December 31, 2024). For further information, see "Item 3. Key Information—A. Selected Financial Data—Reconciliation of Non-GAAP Measures and Ratios to Their Most Directly Comparable IFRS Financial Measures."

***Economic uncertainty may lead to a contraction in our loan portfolio.***

Brazil has historically experienced slower GDP growth rate compared to other emerging markets. The relatively high average GDP growth rate of 3.6% per annum between 2021 and 2023 was driven partly by fiscal stimulus and expansion in the agribusiness sector. However, growth has since slowed, and the GDP growth rate for the period between 2022 and 2024 is estimated at 3.2% per annum. Publicly available forecasts for 2025 generally point to a further moderation in GDP growth, reflecting the effects of tighter monetary conditions, ongoing fiscal uncertainties and a less supportive global environment. This deceleration, coupled with a slowdown in customer demand, increased market competition, regulatory changes, and recent hikes in the SELIC rate, has negatively impacted the growth of our loan portfolio in recent years. Persisting economic uncertainty could further harm the liquidity, businesses, and financial conditions of our customers, leading to reduced consumer spending, higher unemployment, and increased household indebtedness. These factors could, in turn, diminish demand for borrowing, materially and adversely affecting our business.

***Liquidity and funding risks are inherent in our business, and since our main sources of funds are short-term deposits, a sudden shortage of funds could cause an increase in costs of funding and an adverse effect on our revenues and our liquidity levels.***

Liquidity risk is the risk that we either do not have sufficient financial resources available to meet our obligations as they fall due, or that we can only secure such financial resources at excessive cost. This risk is inherent in any retail and wholesale banking business and can be heightened by a number of enterprise-specific factors, including overreliance on a particular source of funding, changes in credit ratings or market-wide phenomena such as market dislocation, including as a result of the continuation or escalation of the war in Ukraine and uncertainties following the ceasefire agreement in the Middle East, high energy prices, inflation or other disruptive events. Constraints in the supply of liquidity, including in interbank lending, can materially and adversely affect the cost of funding of our business, and extreme liquidity constraints may affect our current operations, our growth potential and our ability to fulfill regulatory liquidity requirements.

Our cost of obtaining funds is directly influenced by prevailing interest rates and our credit spreads, and increases in these factors raise our funding costs. While certain global central banks began to lower interest rates in 2024, they remain elevated by historical standards. In Brazil, however, interest rates have risen significantly over the past year as the Brazilian Central Bank responded to persistent inflationary pressures. We cannot assure you that interest rates in Brazil will not remain elevated. A return to periods of relatively high inflation is likely to result in higher operating costs, a decrease in the purchasing power of families with the consequent increase in delinquencies in our credit portfolios, and lower economic growth derived from the tightening of monetary and fiscal policies aimed at containing inflation, among other risks, any of which could have a material adverse effect on our operations, financial condition and prospects. In addition, credit spread variations are market-driven and may be influenced by market perceptions of our creditworthiness. Changes to interest rates and our credit spreads occur continuously and may be unpredictable and highly volatile.

Disruption and volatility in the global financial markets could have a material adverse effect on our ability to access capital and liquidity on financial terms acceptable to us. If wholesale markets financing ceases to become available, or becomes excessively expensive, we may be forced to raise the rates we pay on deposits, with a view to attracting more customers, and/or to sell assets, potentially at depressed prices. The persistence or worsening of these adverse market conditions or an increase in base interest rates could have a material adverse effect on our ability to access liquidity and cost of funding.

We rely primarily on deposits as our main source of funding. As of December 31, 2025, 81% of our customer deposits had remaining maturities of one year or less, or were payable on demand, while 40% of our assets had maturities of one year or more, resulting in a mismatch between the maturities of liabilities and the maturities of assets. The ongoing availability of this type of funding is sensitive to a variety of factors beyond our control, including general economic conditions, the confidence of retail depositors in the economy and in the financial services industry, the availability and extent of deposit guarantees, as well as competition for deposits between banks or with other products. Any of these factors could significantly increase the amount of retail deposit withdrawals in a short period of time, thereby reducing our ability to access retail deposit funding on economically appropriate and reasonable terms, or at all, in the future. If these circumstances arise, this could have a material adverse effect on our operating results, financial condition and prospects.

*[**Table of Contents**](#toc)*<br>

Difficulties or liquidity issues faced by certain financial entities could cause withdrawals of deposits from these entities and volatility in international markets. The spread or potential spread of these or other issues to the broader financial sector could have a material adverse effect on our operating results, financial condition and prospects.

Central banks around the world took extraordinary measures to increase liquidity in the financial markets as a response to the financial crisis and the COVID-19 pandemic. As a result of inflationary pressures beginning in 2021 and persisting through 2023, central banks have reduced or discontinued these measures. If any remaining credit facilities, which are progressively being reduced, were to be rapidly removed or significantly reduced, this could have a material adverse effect on our ability to access liquidity and on our funding costs. Additionally, our activities could be adversely impacted by liquidity tensions arising from generalized drawdowns of committed credit lines to our customers.

Our ability to manage our funding base may also be affected by changes to the regulation on compulsory reserve requirements in Brazil. For more information on the rules on compulsory reserve requirements, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Compulsory Reserve Requirements."

We cannot assure that in the event of a sudden or unexpected shortage of funds in the banking system, we will be able to maintain levels of funding without incurring high funding costs, a reduction in the term of funding instruments or the liquidation of certain assets. If this were to happen, we could be materially adversely affected. Finally, the implementation of internationally accepted liquidity ratios might require changes in business practices that affect our profitability. The liquidity coverage ratio, or "LCR," is a liquidity standard that measures if banks have sufficient high-quality liquid assets to cover expected net cash outflows over a 30-day liquidity stress period. For the observations in this disclosure (exercised with daily balances for October, November and December 2025), Santander Brasil had an LCR of 175.3%, above the 100% minimum requirement. The Net Stable Funding Ratio, or "NSFR," provides a sustainable maturity structure of assets and liabilities so that banks maintain a stable funding profile in relation to their activities. Our NSFR, which must remain at a minimum of 100% beginning from October 1, 2018 according to CMN rules, was 115.0% as of December 31, 2025.

***We may be materially and adversely affected by protectionist trade policies and other measures adopted by the current U.S. administration, including the imposition of additional tariffs on Brazilian products and services.***

The current President of the United States was elected for a second term on November 5, 2024, and took office in January 2025. We have no control over and cannot predict the effect of his administration or policies. Since returning to office, the President's administration has reinforced protectionist economic policies, including the expansion of tariffs on a range of goods from key trading partners such as China, the European Union and Brazil, including a baseline 10% tariff on most imports and higher, reciprocal country- and sector-specific rates. In relation to Brazil, for example, the U.S. government imposed an additional 40% tariff on certain Brazilian imports, including industrial goods, commodities and agricultural products, which took effect, subject to certain exceptions, on August 6, 2025, citing concerns over alleged restrictions on freedom of speech and the political prosecution of the former President of Brazil. These additional 40% tariffs were subsequently lifted in November 2025 although the 10% baseline tariffs remain in place. In February 2026, however, the U.S. Supreme Court held that certain tariffs imposed under the International Emergency Economic Powers Act (IEEPA) were beyond the President's statutory authority, vacating significant components of the tariff regime and reinforcing that tariff-setting power resides with Congress. While the decision has limited the legal basis for the broad emergency tariffs originally imposed, legal and policy uncertainty remains as the U.S. administration has signaled intentions to pursue alternative statutory authorities to re-impose or adjust tariffs and may enact across-the-board levies under other provisions of U.S. trade law. The U.S. government has also publicly threatened further trade actions against Brazil and other "BRICS" countries based on their association with Russia and their efforts to reduce dependence on the U.S. dollar in international trade. Such measures may have a material adverse effect on both Brazil's economy and the global economy. In addition, any additional tariffs or the development of a fully-fledged trade war could exacerbate economic tensions globally, disrupt global trade flows, add to economic uncertainty and have a material adverse effect on both Brazil's economy and the global economy.

Increased tariffs and the potential for further trade restrictions may lead to a slowdown in global trade and economic activity, with disproportionate effects on emerging markets like Brazil. Such developments could result in greater currency volatility, reduced foreign investment flows, higher inflation, and increased interest rates in affected jurisdictions, including Brazil, all of which can negatively impact credit availability, borrowing costs, and the demand for financial products and services. Given our operations in Brazil's financial sector, these adverse macroeconomic impacts could result in lower demand for our financial products and increased funding costs. Additionally, any deterioration in U.S.-Brazil trade relations or regulatory shifts impacting cross-border capital flows could restrict our access to international funding sources or affect the value of assets and liabilities denominated in foreign currencies. As a result, ongoing or future policies implemented by the current U.S. administration may have a material adverse effect on our business, financial condition and results of operations.

***Our cost of funding is affected by our credit ratings, and any risks may have an adverse effect on both variables. Any downgrade in Brazil's, our controlling shareholder's or our credit rating would likely increase our cost of funding, requiring us to post additional collateral under some of our derivative and other contracts and adversely affect our interest margins and results of operations.***

Credit ratings affect the cost and other terms upon which we are able to obtain funding. Rating agencies regularly evaluate us, and their ratings of our long-term debt are based on a number of factors, including our financial strength, conditions that affect the financial services industry and the economic environment in which we operate. In addition, due to the methodology of the main rating agencies, our credit rating is affected by the rating of Brazilian sovereign debt and the rating of our controlling shareholder. If Brazil's sovereign debt or the debt of our controlling shareholder were to be downgraded, our credit rating would also likely be downgraded to a similar degree.

On December 19, 2023, S&P upgraded Brazil's sovereign rating from BB- to BB with a stable outlook. On June 25, 2025, Fitch affirmed Brazil's sovereign rating at BB with a stable outlook. On November 26, 2025, Moody's affirmed Brazil's sovereign rating at Ba1 with a stable outlook after an upgrade from Ba2 on October 1, 2024. Nonetheless, any future downgrade of Brazil's credit rating could negatively impact the trading price of our units and ADRs. Similarly, downgrades of major Brazilian companies could worsen the economic conditions in Brazil, particularly for companies reliant on foreign investment, potentially having a material adverse effect on our business, financial condition, results of operations, and the price of our securities.

Downgrades in Brazil's sovereign credit ratings, those of our controlling shareholder, or in our own ratings, would likely increase our borrowing costs. A rating downgrade could also limit our ability to sell or trade certain products, such as subordinated securities, engage in longer-term or derivative transactions, and retain customers who require a minimum rating threshold to invest. Furthermore, under certain derivative contracts and financial commitments, we may be required to maintain a minimum credit rating or post collateral to avoid termination of such contracts. These outcomes could reduce our liquidity and adversely affect our operations, financial condition, and results.

While certain potential impacts of these downgrades are contractual and quantifiable, the full consequences of a credit rating downgrade are inherently uncertain, as they depend on numerous dynamic, complex and interrelated factors and assumptions, including market conditions at the time of any downgrade, whether the downgrade of our long-term credit rating indirectly downgrades our short-term credit rating, and assumptions about the potential behaviors of various customers, investors and counterparties. Actual outflows could be higher or lower than any hypothetical examples, depending upon certain factors, including the credit rating agency issuing the downgrade, any management or restructuring actions that could be taken to reduce cash outflows, and the potential liquidity impact from loss of unsecured funding (such as from money market funds) or loss of secured funding capacity. Although unsecured and secured funding stresses are included in our stress-testing scenarios and a portion of our total liquid assets is held against these risks, a credit rating downgrade could still have a material adverse effect on us.

Santander Spain's long-term debt in foreign currency is currently rated investment grade by the major rating agencies: A1 stable outlook by Moody's, A+ with a stable outlook by S&P and A with a stable outlook by Fitch. Santander Brasil's long-term debt in foreign currency is currently rated BB with a stable outlook by S&P and Baa3 with a stable outlook by Moody's and was affected as a result of the lowering of Brazil's sovereign credit rating. Any further downgrade in our long-term debt in foreign currency, including as a result of adverse economic conditions in Brazil or globally (such as those caused by the ongoing war between Russia and Ukraine and the war in the Middle East), would likely increase our funding costs and adversely affect our interest margins and results of operations.

We cannot assure that the rating agencies will maintain their current ratings or outlooks. In general, the future evolution of our ratings will be linked, to a large extent, to the impact of the general macroeconomic outlook (including as a result of the continuation or escalation of the wars in Ukraine and the war in the Middle East), inflation and interest rates on our asset quality, profitability and capital, as well as on the rating of Santander Spain. Our failure to maintain favorable ratings and outlooks would likely increase our cost of funding and adversely affect our interest margins and results of operations.

***The effectiveness of our credit risk management is affected by the quality and scope of information available in Brazil.***

In assessing customers' creditworthiness, we rely largely on the credit information available from our own internal databases, certain publicly available customer credit information, information relating to credit contracted, which is provided by the Brazilian Central Bank, and other sources. Due to limitations in the availability of information and the developing information infrastructure in Brazil, our assessment of credit risk associated with a particular customer may not be based on complete, accurate or reliable information. In addition, we cannot assure that our credit scoring systems collect complete or accurate information reflecting the actual behavior of customers or that their credit risk can be assessed correctly. Without complete, accurate and reliable information, we have to rely on other publicly available resources and our internal resources, which may not be effective. As a result, our ability to effectively manage our credit risk and subsequently our allowances for impairment losses may be materially adversely affected.

*[**Table of Contents**](#toc)*<br>

***Our hedging strategy may not be able to prevent losses.***

We use a range of strategies and instruments, including entering into derivative and other transactions, to hedge our exposure to market, credit and operational risks. Nevertheless, we may not be able to hedge all risks to which we are exposed, whether partially or in full. Furthermore, the hedging strategies and instruments on which we rely may not achieve their intended purpose. Any failure in our hedging strategy or in the hedging instruments on which we rely could result in losses to us and have a material adverse effect on our business, financial condition and results of operations.

***Inadequate pricing methodologies for insurance, pension plan and premium bond products may adversely affect us.***

We establish prices and make calculations in relation to our insurance and pension products based on actuarial or statistical estimates. The pricing of our insurance and pension plan products is based on models that include a number of assumptions and projections that may prove to be incorrect, since these assumptions and projections involve the exercise of judgment with respect to the levels and timing of receipt or payment of premiums, contributions, provisions, benefits, claims, expenses, interest, investment results, retirement, mortality, morbidity and persistence. We could suffer losses due to events that are contrary to our expectations as a result of, among others, incorrect biometric and economic assumptions or the use of incorrect actuarial bases in the calculation of contributions and provisions.

Although the pricing of our insurance and pension plan products and the adequacy of the associated reserves are reassessed on a yearly basis, we cannot accurately determine whether our assets supporting our policy liabilities, together with future premiums and contributions, will be sufficient for the payment of benefits, claims and expenses. Accordingly, the occurrence of significant deviations from our pricing assumptions could have an adverse effect on the profitability of our insurance and pension products. In addition, if we conclude that our reserves and future premiums are insufficient to cover future policy benefits and claims, we will be required to increase our reserves and record these effects in our financial statements, which may have a material adverse effect on us.

***Social and environmental risks may have a material adverse effect on us.***

As part of the risk analysis we conduct with our clients, we consider several risk factors, including environmental issues (such as soil and groundwater contamination, deforestation, or lack of environmental permits), social issues (such as slavery-like working conditions or the impact of projects on indigenous people) and, more recently, climate issues, considering both physical and transition risks. Any failure or neglect on our part to identify and accurately assess these factors and potential risks before entering into proposed transactions with our customers could harm our image and reputation, and have a material adverse effect on our business, results of operations, and financial condition.

Moreover, we are also exposed to the risk that our assessment of a product or service we provide, or an investment we have made, as socially or environmentally responsible may be challenged by customers, regulators, or third parties. There has been an increase in regulatory and investor demand for sustainability-linked financial instruments. This growing interest in sustainability factors, along with increased demand for and scrutiny of sustainability-related disclosures by financial institutions, has heightened the risk that we could be perceived as, or accused of, making inaccurate or misleading statements regarding the investment strategies of our self-managed investment funds or our sustainability efforts and initiatives, commonly referred to as "greenwashing." Such perceptions or accusations could damage our reputation, result in litigation or regulatory enforcement actions, and adversely affect our business.

Since 2021, the Brazilian Central Bank has expanded and enhanced the regulatory framework governing the management and disclosure of social, environmental and climate risks. The rules introduced by CMN Resolution No. 4,943/2021 and related regulations require financial institutions to adopt a Social, Environmental and Climate Responsibility Policy, integrate climate-related risks into their risk management processes, strengthen ESG governance and comply with enhanced disclosure and prudential reporting obligations. These requirements apply to risks arising from our activities as well as those of our counterparties, affiliates, suppliers and service providers.

At the international level, the European Banking Authority issued ESG risk management guidelines in 2023, which reinforce global supervisory expectations.

*[**Table of Contents**](#toc)*<br>

Any failure to comply with these obligations or to adequately identify, assess or manage social, environmental or climate-related risks could result in supervisory actions or sanctions and could materially and adversely affect our business, financial condition and results of operations.

For more information on the new regulatory requirements issued by the Brazilian Central Bank relating to sustainability requirements applicable to Brazilian financial institutions, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Sustainability Requirements Applicable to Financial Institutions."

***The value of the collateral securing our loans may decline and become insufficient, and we may be unable to realize the full value of the collateral securing our loan portfolio.***

The value of the collateral securing our loan portfolio may fluctuate or decline due to factors beyond our control, including as a result of macroeconomic factors, especially those affecting Brazil. Such as natural disasters (including as a result of climate change). We may also lack sufficiently recent information on collateral values, which may result in an inaccurate assessment for impairment losses of our loans secured by such collateral. If any of the above were to occur, we may need to make additional provisions to cover actual impairment losses, which could materially and adversely affect our results of operations and financial condition.

***We may face significant challenges in possessing and realizing value from collateral with respect to loans in default.***

If we are unable to recover sums owed to us under secured loans in default through extrajudicial measures such as restructurings, our last recourse with respect to such loans may be to enforce the collateral secured in our favor by the applicable borrower. Depending on the type of collateral granted, we either have to enforce such collateral through the courts or through extrajudicial measures. However, even where the enforcement mechanism is duly established by applicable law, Brazilian law allows borrowers to challenge the enforcement in the courts, even if such challenge is unfounded, which can delay the realization of value from the collateral. In addition, our secured claims under Brazilian law will in certain cases rank below those of preferred creditors such as employees and tax authorities. As a result, we may not be able to realize value from the collateral or may only be able to do so to a limited extent or after a significant amount of time, thereby potentially adversely affecting our financial condition and results of operations.

***We are subject to market, operational and other related risks associated with our derivative transactions and our investment positions that could have a material adverse effect on us.***

We enter into derivative transactions for trading purposes, as well as for hedging purposes. We are subject to market, credit and operational risks associated with these transactions, including basis risk (the risk of loss associated with variations in the spread between the asset yield and the funding and/or hedge cost) and credit or default risk (the risk of insolvency or other inability of the counterparty to a particular transaction to perform its obligations thereunder, including providing sufficient collateral). We also hold securities in our own portfolio as part of our investment and hedging strategies.

Financial instruments, including derivative instruments and securities, represented 89.2% of our total assets as of December 31, 2025. As of December 31, 2025, the notional value of derivatives in our books amounted to R$2,863 billion (with a market value of R$65,808 million of assets and R$60,012 million of liabilities).

Any realized or unrealized future gains or losses from these investments or hedging strategies could have a significant impact on our income. These gains and losses, which we account for when we sell or mark to market investments in financial instruments, can vary considerably from one period to another. If, for example, we enter into derivatives transactions to protect ourselves against decreases in the value of the real or in interest rates and the real instead increases in value or interest rates increase, we may incur financial losses. We cannot forecast the amount of gains or losses in any future period, and the variations experienced from one period to another do not necessarily provide a meaningful forward-looking reference point. Gains or losses in our investment portfolio may create volatility in net revenue levels, and we may not earn a return on our consolidated investment portfolio or on a part of the portfolio in the future. Any losses on our securities and derivative financial instruments could materially and adversely affect our operating income and financial condition. In addition, any decrease in the value of these securities and derivatives portfolios may result in a decrease in our capital ratios, which could impair our ability to engage in lending activity at the levels we currently anticipate.

The execution and performance of these transactions depend on our ability to maintain adequate control and administration systems. Our ability to adequately monitor, analyze and report derivative transactions continues to depend, largely, on our information technology systems. Any deficiencies in these controls or systems could heighten the risks associated with derivative transactions and have a material adverse effect on us. The use of derivative instruments may also give rise to other risks, including valuation risk, model risk and market liquidity risk, particularly during periods of volatility or market stress. In such circumstances, the fair value of derivative positions may fluctuate significantly, affecting our results and regulatory capital.

***Failure to successfully implement and continue to improve our risk management policies, procedures and methods, including our credit risk management systems, could materially and adversely affect us, and we may be exposed to unidentified or unanticipated risks.***

Risk management is a central part of our activities. We seek to manage and control our risk exposure through a forward-looking management model, based on our governance and advanced risk management tools, supported by our risk culture. While our management model uses a broad and diversified set of risk monitoring, control and mitigation techniques, such management model may not be fully effective at mitigating all types of risks in all economic or market environments, including risks that we may fail to identify or anticipate.

We use certain qualitative tools and metrics for managing market risk, including our use of value at risk, or "VaR," and statistical modeling tools, which are based on observed historical market behavior. We apply statistical and other tools to these observations to arrive at quantifications of our risk exposures. These tools and metrics may fail to predict future risk exposures. These risk exposures could, for example, arise from factors we did not anticipate or correctly evaluate in our statistical models. As a result, our losses could be significantly higher than historical measures indicate. In addition, our statistical models may not take all risks into account or measure emerging risks correctly.

Our approach to managing risks could prove insufficient, exposing us to material unanticipated losses. We could face adverse consequences (i) if our decisions are based on models that are poorly developed, implemented or used, (ii) if the modelled outcome is misunderstood or used for purposes for which it was not designed, or (iii) if the data and inputs used in the models are incorrect or insufficient. If existing or potential customers or counterparties believe our risk management is inadequate, they could take their business elsewhere or seek to limit their transactions with us. Any of these factors could have a material adverse effect on our reputation business, financial condition and results of operations.

We also face risks from operational losses that may occur due to inadequate processes, people and systems failures or even from external events like natural disasters, terrorism, robbery and vandalism. Despite the operational risk management process supported by the Board of Directors and the internal audit tests, the internal controls and procedures effectiveness may not be fully adequate or sufficient to avoid all the known and unknown operational risks. We have suffered losses from operational risk in the past, including losses related to the migration of customer accounts in connection with acquisitions, phishing scams perpetuated by third parties and information system platform upgrades. There can be no assurance that we will not suffer material losses from operational risk in the future, including losses related to security breaches.

As a retail bank, one of the main types of risks inherent in our business is credit risk. For example, an important feature of our credit risk management system is the use of an internal credit rating to assess the particular risk profile of individual customers and SMEs. As this process involves detailed analyses of the customer, taking into account both quantitative and qualitative factors, it is subject to human or information technology systems errors. In exercising their judgement regarding our customers' current or future credit risk behavior, our management models may not always be able to assign an accurate credit rating, which may result in a higher exposure to credit risks than indicated by our risk rating system.

Some of the models and other analytical and judgement-based estimations we use in managing risks are subject to review by, and require the approval of, our regulators. If models do not comply with all their expectations, our regulators may require us to make changes to such models, may approve them with additional capital requirements or may restrict or preclude their use. Any of these possible situations could have a material impact on our business, financial condition and results of operations.

We set concentration limits according to risk appetite, we develop risk policies and reviews to manage credit risk concentration, and we are subject to regulatory limits on large exposures. However, if we fail to anticipate deteriorating sectors or regions, do not comply with internal or regulatory concentration limits, or if one or more of our largest borrowers fail to service their loans, our operating results, financial condition and prospects could be adversely affected.

Failure to effectively implement, consistently monitor or continuously improve our credit risk management system may result in an increase in the level of nonperforming loans and a higher risk exposure for us, which could have a material adverse effect on us. In addition, failure to successfully execute any of our decisions and actions affecting or changing our practices, operations, priorities, strategies, policies, procedures, or frameworks, could have a material adverse effect on us.

***Failure to adequately protect ourselves against risks relating to cybersecurity could materially and adversely affect us. We are also subject to increasing scrutiny and regulation governing cybersecurity risks.***

We face various cybersecurity risks, including but not limited to the intrusion into our information technology systems and platforms by ill-intentioned third parties, infiltration of malware (such as computer viruses) into our systems, contamination (whether intentional or accidental) of our networks and systems by third parties with whom we exchange data, unauthorized access to confidential customer and/or proprietary data by persons inside or outside our organization, ransomware affecting our services and end-user technology, social engineering and phishing attacks, information leaks and cyberattacks causing systems degradation or service unavailability that may result in business losses.

We may not be able to successfully protect our information technology systems and platforms against such threats. In recent years, we have seen increased targeting of the computer systems of companies and organizations, and the techniques used to obtain unauthorized, improper or illegal access to information technology systems have become increasingly complex and sophisticated. Furthermore, such techniques change frequently and are often not recognized or detected until after they have been launched and can originate from a wide variety of sources, including not only cybercriminals, but also activists and rogue states. Cyberattacks, data breaches, data losses and other security incidents, including fraudulent withdrawal of money, can result from, among other things, inadequate personnel, inadequate or failed internal control processes and systems, or external events or actors that interrupt normal business operations and may include disruptions, failures, service outages, unauthorized access or misuse, software bugs, server malfunctions, software and hardware failure, defective software or hardware updates, malware and ransomware, social engineering and phishing attacks, denial-of-service attacks, misconduct, fraud and other events that could have a serious impact on us. Cyberattacks could give rise to the loss of significant amounts of customer data and other sensitive information, as well as significant levels of liquid assets (including cash). In addition, cyberattacks could disrupt our electronic systems used to service our customers.

The professionalization of cybercriminals has produced a worsening threat landscape increasing the frequency and severity of cyberattacks that are impacting businesses, third parties, critical infrastructure and even governments. This situation has made cybersecurity a top risk concern for all industries, including the financial sector.

Our greater reliance on digital systems also makes cybersecurity one of the main nonfinancial risks of the business. Our goal is to make Santander Brasil a cyber-resilient organization that can quickly prevent, detect and respond to cyberattacks by constantly improving our defenses. This aligns with the objectives of the European Union's Digital Operational Resilience Act, which aims to strengthen the IT security of financial entities and ensure resilience in the event of severe operational disruptions, and with the Brazilian Bill of Law No. 4,752/2025, which creates the National Digital Security and Resilience Program to implement the Cybersecurity Legal Framework in Brazil.

If we fall victim to successful cyberattacks or experience cybersecurity, operational or data breaches and other security incidents, including the fraudulent withdrawal of money, in the future, we may incur substantial costs and suffer other negative consequences, such as remediation costs (liabilities for stolen assets or information, or repairs of system damage, among others), increased cybersecurity protection costs, lost revenues arising from the unauthorized use of proprietary information or the failure to retain or attract customers following an attack, as already mentioned, litigation and legal risks, increased insurance premiums, reputational damage affecting our customers' and investors' confidence, as well as damages to our competitiveness, stock price and long-term shareholder value.

We are also subject to increasing scrutiny and regulation governing cybersecurity risks. Such regulation is fragmented and constantly evolving, and includes CMN Resolution No. 4,893/2021 and proposed new regulation. See "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Regulations on Cybersecurity" and "Item 16K. Cybersecurity." We could be adversely affected if new legislation or regulations are adopted or if existing legislation or regulations are modified such that we are required to alter our systems or require changes to our business practices or policies. A failure to implement all or some of these new global and local regulations, which in some cases have severe sanctions regimes, could also have a material adverse effect on us. If we fail to effectively manage our cybersecurity risk, for example, by failing to update our systems and processes in response to emerging technologies and to new threats, this could harm our reputation and adversely affect our operating results, financial condition and prospects through the payment of customer compensation or other damages, litigation expenses, regulatory penalties and fines and/or the loss of assets. Furthermore, upon a failure to comply with applicable law and regulations, we may be ordered to change our business practices, policies or systems in a manner that adversely impacts our operating results.

*[**Table of Contents**](#toc)*<br>

In addition, we may also be subject to cyberattacks against critical infrastructure in Brazil. Our information technology systems are dependent on such critical infrastructure, and any cyberattack against such critical infrastructure could negatively affect our ability to service our customers. As we do not operate such critical infrastructure, we have limited ability to protect our information technology systems from the adverse effects of such a cyberattack. See "Item 4. Information on the Company—B. Business Overview" and "Item 16K. Cybersecurity."

It is important to highlight that even when a failure of or interruption in our systems or facilities is resolved in a timely manner or an attempted cyber incident or other security breach is successfully avoided or thwarted, normally substantial resources are expended in doing so, and we may be required to take actions that could adversely affect customer satisfaction or behavior, as well as represent a threat to our reputation.

For additional information, see also "—We are subject to increasing scrutiny and regulation from data protection laws, including penalties in the event of noncompliance with the terms and conditions of certain new European and Brazilian regulations" and "—Failure to protect personal information could adversely affect us."

***We are subject to counterparty risk in our business.***

We are exposed to counterparty risk in addition to credit risks associated with lending activities. Counterparty risk may arise from, for example, investing in securities of third parties, entering into derivative contracts under which counterparties have obligations to make payments to us, or executing securities, futures, currency or commodity trades from proprietary trading activities that fail to settle at the required time due to non-delivery by the counterparty or systems failure by clearing agents, clearinghouses or other financial intermediaries.

We routinely transact with counterparties in the financial services industry, including brokers and dealers, commercial banks, investment banks, mutual funds, hedge funds and other institutional customers, as well as counterparties in various other industries. Defaults by, and even rumors or questions about the solvency of, certain of our counterparties, including financial institutions and the financial services industry generally, have led to market-wide liquidity problems and losses or defaults by other counterparties. Many of the routine transactions we enter into expose us to significant credit risk in the event of default by one of our major counterparties.

We or certain of our counterparties may incur losses or defaults for a wide variety of reasons, including defaults by certain of our counterparties, by business with which our counterparties transact, rumors or questions about the solvency of our counterparties or significant market participants, as well as evidence or rumors of fraud or improper accounting practices among certain of our counterparties or significant market participants, including both financial and nonfinancial institutions. If any of these problems were to materialize, as they have in past among large Brazilian corporations, the otherwise routine transactions that we have entered into with our counterparties could have a material adverse effect on our business, financial condition and results of operations.

If these risks give rise to losses, this could materially and adversely affect us. Our loan portfolio does not have any specific concentration exceeding 10% of our total loans. As of December 31, 2025, 1.0% of our loan portfolio is allocated to our largest debtor and 3.3% to our next 10 largest debtors. However, we cannot assure this will continue to be the case or that we will not incur significant losses from counterparty defaults despite the concentration levels described above. If these counterparty risks give or continue to give rise to losses, our business, financial condition and results of operations could materially and adversely be affected.

***Our financial results are constantly exposed to market risk. We are subject to fluctuations in interest rates and other market variables, which may materially and adversely affect us and our profitability.***

Our financial results are constantly exposed to market risk, including trading risks and structural risks.

Market risk affects (i) our interest income/(charges), (ii) the market value of our assets and liabilities, in particular of our securities holdings, loans and deposits and derivatives transactions, and (iii) other areas of our business such as the volume of loans originated or credit spreads. Market risk could also include unforeseen risks arising during periods of market disruption or when market prices do not reflect fundamental values. Economic activities exposed to market risk include (a) transactions where risk is assumed as a consequence of potential changes in interest rates, inflation rates, exchange rates, stock prices, credit spreads, commodity prices, volatility and other market factors, (b) the liquidity risk from our products and markets; and (c) balance sheet-related liquidity risk.

Interest rate risk arises from movements in interest rates that reduce the value of a financial instrument, a portfolio or Santander Brasil. It can affect loans, deposits, debt securities, most assets and liabilities held for trading, and derivatives. Interest rates are sensitive to many factors beyond our control, including monetary policies, regulatory actions affecting the financial sector and domestic and international economic and political conditions. Variations in interest rates could affect the interest earned on our assets and the interest paid on our borrowings, thereby affecting our interest income/(charges), which constitutes the majority of our revenue, and could reduce our growth rate or result in losses. In addition, costs we incur as we implement strategies to reduce interest rate exposure could increase in the future, which could in turn affect our results.

*[**Table of Contents**](#toc)*<br>

Increases in interest rates may reduce the volume of loans we originate. Sustained high interest rates have historically discouraged customers from borrowing and have resulted in increased or fluctuations in delinquencies in outstanding loans and deterioration in the quality of assets. Increases in interest rates may reduce the value of our financial assets and may reduce gains or require us to record losses on sales of our loans or securities. In particular, certain assets are constantly marked-to-market and are therefore affected by changes in prevailing interest rates. This process may result in significant reductions in book values and to impairment losses. Additionally, a flattening or inversion of the yield curve, combined with persistent inflationary pressures, could adversely affect our business and results of operations.

Conversely, a decrease in interest rates may reduce the rates on many of our interest-bearing deposit products. However, even with a possible reduction of the rates on our interest-bearing deposit products as a result of a decrease in the SELIC rate, the total impact on our interest margin will depend, among other factors, on the difference between medium and long-term interest rates compared to overnight rates. In particular, an inverted yield curve in a high interest rate environment may adversely impact our interest-bearing products, and if such a scenario were to persist, may adversely affect our results of operations.

Exchange rate risk, in turn, is the possibility of loss because the currency of a long or open position will depreciate against the base currency. We are exposed to foreign exchange rate risk as a result of mismatches between assets and liabilities denominated in different currencies. Fluctuations in the exchange rate between currencies may negatively affect our earnings and value of our assets and securities.

Equity risk is the possibility of loss from open positions in securities if their market price or expected future dividends fall. It affects shares, stock market indices, convertible bonds and derivatives with shares as the underlying asset (put, call, equity swaps, etc.). We are exposed to equity price risk in our investments in equity securities in the banking book and in the trading portfolio.

The performance of financial markets may cause changes in the value of our investment and trading portfolios. Prolonged volatility in global equity and fixed-income markets —driven by geopolitical uncertainty, monetary tightening cycles, and investor risk aversion—has had a significant impact on the financial sector. Continued volatility may affect the value of our investments in equity securities and, depending on their fair value and future recovery expectations, could result in a permanent impairment requiring write-offs against our results.

Additionally, we are also exposed to more complex market risks such as correlation risk, market liquidity risk, prepayment or cancellation risk and subscription risk. In addition, we are also exposed to balance sheet liquidity risk, which is different from market liquidity risk and refers to the possibility of loss caused by forced disposal of assets or cash flow imbalance if the bank meets its payment obligations late or at excessive cost. Such situations may cause losses through forced asset sales or margin compression resulting from mismatches between expected inflows and outflows.

If any of these risks were to materialize, our net interest income or the market value of our assets and liabilities could suffer a material adverse impact.

***Market conditions have resulted and could result in material changes to the estimated fair values of our financial assets. Negative fair value adjustments could have a material adverse effect on our operating results, financial condition and prospects.***

In the past, financial markets have been subject to significant stress resulting in steep falls in perceived or actual financial asset values, particularly due to volatility in global financial markets and the resulting widening of credit spreads, including as a result of the war in Ukraine and uncertainties following the ceasefire agreement in the Middle East, high inflation (including high energy prices) and other disruptive events. We hold significant exposures to securities, loans and other investments recorded at fair value which exposes us to potential negative fair value adjustments. Asset valuations in future periods, reflecting then-prevailing market conditions, may result in negative changes in the fair values of our financial assets and these may also translate into increased impairments, including as a result of more stringent regulatory or reputation requirements. In addition, the value ultimately realized by us on disposal may be lower than the current fair value. Any of these factors could require us to record negative fair value adjustments, which may have a material adverse effect on our operating results, financial condition or prospects.

*[**Table of Contents**](#toc)*<br>

In addition, to the extent that fair values are determined using financial valuation models, such values may be inaccurate or subject to change, as the data used by such models may not be available or may become unavailable due to changes in market conditions, particularly for illiquid assets, and particularly in times of economic instability. In such circumstances, our valuation methodologies require us to make assumptions, judgements and estimates in order to establish fair value. Reliable assumptions are difficult to make and are inherently uncertain while valuation models are inherently complex and imperfect predictors of actual results. Any consequential impairments or write-downs could have a material adverse effect on our operating results, financial condition and prospects.

***We face risks related to market concentration.***

Concentration risk is the risk associated with potential high financial losses triggered by significant exposure to a particular component of risk, whether it be related to a particular counterparty, industry or geographic concentration. Examples of such risks include significant exposure to a single counterparty, to counterparties operating in the same economic sector or geographical region, or to financial instruments that depend on the same index or currency.

We believe that an excessive concentration with respect to a particular risk factor could generate a relevant financial loss for us, especially if the risk is one described in the "Item 3. Key Information—D. Risk Factors" section of this annual report. We recognize the importance of this risk and the potential impacts that may affect our portfolio and results of operations.

***The financial problems faced by our customers could adversely affect us.***

Potential market turmoil and economic recession could materially and adversely affect the liquidity, credit ratings, businesses and/or financial condition of our customers, which could in turn increase our non-performing loans ratio, impair our loans and other financial assets and result in decreased demand for borrowings and deposits in general. In addition, our customers may significantly decrease their risk tolerance for non-deposit investments such as stocks, bonds and mutual funds, which would adversely affect our fee and commission income. Any of the conditions described above could have a material adverse effect on our business, financial condition and results of operations.

In addition, our customers may further significantly decrease their risk tolerance to non-deposit investments such as stocks, bonds and mutual funds, which would adversely affect our fee and commission income. Any of the conditions described above could have a material adverse effect on us.

***We engage in transactions with related parties that others may not consider to be on an arm's-length basis.***

We and our affiliates have entered into a number of services agreements pursuant to which we render and/or receive services, such as administrative, accounting, consulting, finance, treasury, legal services and others from (or provide such services to) related parties. We are likely to continue to engage in transactions with such related parties (including our controlling shareholder) that others may not consider to be on an arm's-length basis. Future conflicts of interests may arise between us and any of our affiliates, or among our affiliates, which may not be resolved in our favor. See "Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions."

***Changes in accounting standards could impact reported earnings.***

Accounting standard setters and other regulatory bodies periodically change the financial accounting and reporting standards that govern the preparation of our consolidated financial statements. These changes can materially impact how we record and report our financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in the restatement of prior period financial statements. For further information about developments in financial accounting and reporting standards, see note 1 to our audited consolidated financial statements included elsewhere in this annual report.

*[**Table of Contents**](#toc)*<br>

***Our financial statements are based in part on assumptions and estimates that impact the results of our operations.***

The preparation of financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based upon amounts that differ from those estimates. Estimates, judgments and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected. The accounting policies deemed critical to our results and financial position, based upon materiality and significant judgments and estimates, include impairment of financial assets measured at amortized cost, goodwill impairment, valuation of financial instruments, impairment of financial assets measured at fair value through other comprehensive income, deferred tax assets provision and pension obligation for liabilities.

If the judgment, estimates and assumptions we use in preparing our consolidated financial statements are subsequently found to be incorrect or misstated, there could be a material effect on our results of operations and a corresponding effect on our funding requirements and capital ratios. For further information about our accounting estimates, see note 1 to our audited consolidated financial statements included elsewhere in this annual report, and for further information about our provisions for judicial and administrative proceedings, see note 22 to our audited consolidated financial statements included elsewhere in this annual report.

***Our business is highly dependent on the proper functioning of our information technology systems.***

Our business is highly dependent on the ability of our information technology systems to accurately process a large number of transactions across numerous and diverse markets and products in a timely manner, and on our ability to rely on our digital technologies, computer and email services, software, and networks, as well as on the secure processing, storage and transmission of confidential data and other information in our computer systems and networks. The proper functioning of our financial control, risk management, accounting, customer service and other data processing systems is critical to our business and our ability to compete effectively.

We do not operate all of our redundant systems on a real-time basis and cannot assure that our business activities would not be materially disrupted if there were a partial or complete failure of any of these primary information technology systems or communication networks. Such failures could be caused by, among other things, major natural catastrophes, software bugs, computer virus attacks, conversion errors due to system upgrading, security breaches caused by unauthorized access to information or systems, or intentional malfunctions or loss or corruption of data, software, hardware or other computer equipment. We have experienced interruptions in our information technology systems in the past and we cannot assure that we will not suffer any such interruptions in the future, or that we will be able to identify and rectify these within a window of time that prevents any disruption. Any such events or failures could disrupt our business and impair our ability to provide our services and products effectively to our customers, which could adversely affect our reputation as well as our business, results of operations and financial condition.

Our ability to remain competitive and achieve further growth will depend in part on our ability to upgrade our information technology systems and increase our capacity on a timely and cost-effective basis. We must continually make significant investments in, and improvements to, our information technology infrastructure and information management systems and networks in order to meet the needs of our customers and to comply with evolving regulatory requirements, and operational and resilience expectations. While we expect to continue investing, there is no assurance we will achieve or sustain the level of capital expenditures necessary to support the continuous improvement and upgrading of our information technology infrastructure and information management systems and networks. There is also no assurance that our investment strategy will be successful. To the extent we are dependent on any particular technology or technological solution, we may face adverse consequences if such technology or technological solution becomes noncompliant with existing industry standards or applicable laws, rules or regulations, fails to meet or exceed the capabilities of our competitors' equivalent technologies or technological solutions, becomes increasingly expensive to service, retain and update, becomes subject to third-party claims of intellectual property infringement, misappropriation or other violation, has security vulnerabilities or malfunctions or functions in a way we did not anticipate or are unable to rectify.

*[**Table of Contents**](#toc)*<br>

Additionally, new technologies and technological solutions, such as AI, distributed ledger technology, or DLT, and quantum computing, are continually being released. As such, it is difficult to predict the problems we may encounter in improving our technologies' functionality. There is no assurance that we will be able to successfully adopt new technology as critical systems and applications become obsolete and better ones become available. Large-scale programs to modernize technology, data and reporting — including compliance with evolving prudential reporting frameworks — are complex and time-consuming (often requiring many years to execute). Delays in execution, data-quality issues, or control weaknesses may lead to supervisory actions, fines, remediation costs or constraints on strategic initiatives. DLT, including blockchain and related infrastructures, is increasingly being explored and adopted across financial markets and payment systems. While these technologies may offer greater efficiency, transparency and traceability, they also introduce specific technological and operational risks and challenges that may affect the integrity and resilience of financial systems. DLT relies on cryptographic consensus mechanisms, distributed governance and, in some cases, open-source protocols, all of which may be vulnerable to design flaws, governance disputes and security vulnerabilities. Limitations in scalability, latency and interoperability across networks may also hinder performance and reliability. Moreover, divergent regulatory approaches across jurisdictions and potential fragmentation of market infrastructures and compliance tools could amplify operational and compliance risks. A growing reliance on DLT-based platforms could disrupt traditional payment, custody and settlement processes, creating dependencies on new technological frameworks and third-party providers. Financial institutions that fail to adapt to such developments may face increased competitive and operational risks. As legacy systems migrate toward hybrid or fully distributed environments, we may encounter transitional, technological and integration challenges affecting system resilience, data integrity and cybersecurity. These factors, individually or in combination, could adversely affect our ability to deliver critical services without disruption, to comply with evolving regulatory and supervisory expectations, and to maintain secure and continuous operations.

Quantum computing poses a significant emerging risk to existing encryption standards by potentially creating new security vulnerabilities, enabling data breaches, authentication bypasses and other new types of cyber threats. As regulatory and supervisory scrutiny of post-quantum readiness increases, financial institutions face growing compliance and implementation pressures. The transition to post-quantum cryptography is complex due to legacy systems, interdependent banking infrastructures and evolving international standards. Uneven or delayed adoption across the financial ecosystem could prolong reliance on quantum-vulnerable encryption, thereby increasing systemic exposure and delaying a coordinated and secure transition.

Any failure to effectively improve or upgrade our information technology infrastructure and information management systems and networks, or to timely adapt to emerging technologies, evolving cybersecurity threats or changing regulatory standards, could have a material adverse effect on us.

***Failure to protect personal information could adversely affect us.***

Like other financial institutions, in conducting our banking operations, we receive, manage, hold, transmit and otherwise process certain proprietary, confidential, sensitive and personal data, including personal data of customers and employees, as well as a large number of assets. The sharing, use, disclosure and protection of this information are governed by various Brazilian and foreign laws and regulations.

Although we have procedures and controls in place to safeguard personal and other confidential or sensitive information in our possession, unauthorized access or disclosures could subject us to legal actions and administrative sanctions, as well as damages and reputational harm that could materially and adversely affect our operating results, financial condition and prospects. Furthermore, our business is exposed to risk from employees' potential noncompliance with policies, misconduct, negligence or fraud, which could result in regulatory sanctions and serious reputational and financial harm. We also face the risk that the design of our controls and procedures prove to be inadequate or are circumvented such that the data we hold is incomplete, not recoverable or not securely stored. Moreover, it is not always possible to deter or prevent employee misconduct, and the precautions we take to detect and prevent this activity may not always be effective. In addition, we may be required to report events related to information security issues, events where customer information may be compromised, unauthorized access to our systems and other security breaches, to the relevant regulatory authorities. Any material disruption or slowdown of our systems could cause information, including data related to customer requests, to be lost or delivered to our customers with delays or errors, which could adversely affect our reputation, reduce demand for our services and products and could materially and adversely affect us. If we cannot maintain effective and secure electronic data and information, management and processing systems or if we fail to maintain complete physical and electronic records, this could result in disruptions to our operations, claims from customers, regulators, employees and other parties, violations of applicable privacy and other laws, regulatory sanctions and serious reputational and financial harm to us.

*[**Table of Contents**](#toc)*<br>

Moreover, during the heights of the COVID-19 pandemic, we permitted or required a majority of our employees to work remotely, which led to increased vulnerability of our systems and the risk of cyber-attacks. Though the majority of our employees are now working in person at our offices, work-from-home policies may lead to continued vulnerability to the extent certain of our employees elect to work away from our premises and access our networks remotely. This trend, combined with our customers' increased reliance on digital banking products and other digital services, including mobile payment products, has increased the risk of cyberattacks, frauds, data breaches, data losses and other security incidents.

Furthermore, any failure or disruption of our operational processes or systems, or any cyberattack, frauds, data breach, data loss or other security incident affecting our systems or those of our third-party vendors, could adversely affect our business, financial condition or reputation, and could result in significant legal or regulatory exposure. We prioritize early identification, monitoring and mitigation of risks (including those resulting from our interactions with third parties) in our goal to provide a resilient and secure operational environment. In this regard, although (i) we have policies, procedures and controls in place designed to safeguard proprietary, confidential, sensitive and personal data, (ii) we take protective technical measures and monitor and develop our systems and networks to protect our technology infrastructure, data and information from misappropriation, frauds or corruption, and (iii) we work with our clients, vendors, service providers, counterparties and other third parties to develop secure data and information processing, collection, authentication, management, usage, storage and transmission capabilities and to ensure the eventual destruction of proprietary, confidential, sensitive and personal data, we, our third-party vendors or other third parties with which we do business have been and may continue to be subject to cyberattacks, data breaches, data losses and other security incidents. For example, on May 14, 2024, Santander Spain announced that they had become aware of an unauthorized access to a database that included certain customer and employee information hosted by a third-party provider.

The implementation of our cybersecurity policies, procedures, controls and technical measures is designed to reduce the risk of such cyberattacks, data breaches, data losses and other security incidents but does not guarantee full protection or a risk-free environment. This is especially applicable in the current global environment, with the war in Ukraine and uncertainties following the ceasefire agreement in the Middle East resulting in an increased risk of cyberattacks, data breaches, data losses and other security incidents, and other disruptions in response to, or retaliation for, the sanctions and costs imposed on Russia and certain other countries directly or indirectly involved in these wars. While we generally perform cybersecurity due diligence on our key vendors, because we do not control our vendors and our ability to monitor their cybersecurity is limited, we cannot ensure the cybersecurity measures they take will be sufficient to protect any information we share with them. Due to applicable laws and regulations or contractual obligations, we may be held responsible for cyberattacks, data breaches, data losses and other incidents attributed to our vendors as they relate to the information we share with them.

We have seen in recent years the information technology systems and networks of companies and organizations being increasingly targeted, and the techniques used to obtain unauthorized, improper or illegal access to such information technology systems and networks have become increasingly complex and sophisticated, including through the use of AI. Furthermore, such techniques change frequently and are often not recognized or detected until after they have been launched and can originate from a wide variety of sources, including organized crime, hackers, activists, terrorists, nation-states, nation-state supported actors and others, any of which may see their effectiveness enhanced by the use of AI. As attempted attacks continue to evolve in scope and sophistication, we may incur significant costs in order to modify, adapt or enhance our protective measures against such attacks, or to investigate or remediate any vulnerability or resulting breach, or in communicating cyberattacks, data breaches, data losses or other security incidents to our customers, affected individuals or regulators, as applicable.

If we cannot maintain effective and secure proprietary, confidential, sensitive and personal data, or if we or our third-party vendors fall victim to successful cyberattacks, penetrations, compromises, breaches or circumventions of our information technology systems or networks or experience other data breaches, data losses or other security incidents in the future, we may incur substantial costs and suffer other negative consequences, such as disruption to our operations, misappropriation of proprietary, confidential, sensitive or personal data, remediation costs (including liabilities for stolen assets or information, repairs of system damage, among others), increased cybersecurity protection costs, lost revenues arising from the unauthorized use of proprietary, confidential, sensitive or personal data or the failure to retain or attract our customers following an operational or security incident, litigation and legal risks (including claims from customers, employees or other third parties, regulatory action, reporting obligations, investigation, fines and penalties), increased insurance premiums, reputational damage affecting our customers' and our investors' confidence, as well as damages to our competitiveness, stock price and long-term shareholder value. In addition, our remediation efforts may not be successful, and we may not have adequate insurance to cover these losses. While we maintain insurance coverage, we cannot assure you that such coverage will be adequate or otherwise protect us from liabilities or damages with respect to claims alleging compromises of proprietary, confidential, sensitive or personal data or otherwise relating to privacy, data protection and cybersecurity matters. In addition, we cannot be sure that our existing insurance coverage will continue to be available on acceptable terms or at all, or that our insurers will not deny coverage to any future claim. Moreover, even when a failure of or interruption in our or our third-party vendors' systems or facilities is resolved in a timely manner or an attempted cyberattack, data breach, data loss or other security incident is successfully avoided or thwarted, substantial resources and management attention are expended in doing so, and to successfully avoid or resolve any such incidents, we may be required to take actions that could adversely affect customer satisfaction or retention, as well as harm our reputation.

*[**Table of Contents**](#toc)*<br>

Any of such cyberattacks, frauds, data breaches, data losses and other security incidents described above could have a material adverse effect on our business, financial condition and results of operations. For additional information, see also "—We are subject to increasing scrutiny and regulation from data protection laws, including penalties in the event of noncompliance with the terms and conditions of certain new European and Brazilian regulations" and "—Failure to adequately protect ourselves against risks relating to cybersecurity could materially and adversely affect us. We are also subject to increasing scrutiny and regulation governing cybersecurity risks."

***Damage to our reputation could cause harm to us.***

Maintaining a robust risk management framework based on sound ethical principles and corporate values is critical to protect our reputation and our brand, attract and retain customers, investors and employees and conduct business transactions with counterparties. Damage to our reputation could materially and adversely affect how we are perceived by current and potential clients, investors, vendors, partners, regulators and other third parties, which in turn could have a material adverse effect on our operating results, financial condition, and prospects as well as damage our customers' and investors' confidence and the market price of our securities. Harm to our reputation could arise from numerous sources, including, among others, employee misconduct(such as fraud or unethical behavior), litigation or regulatory enforcement, failure to deliver minimum standards of service and quality, negative perceptions regarding our ability to maintain the security of our technology systems and protect customer data (including as a result of a cyberattack, data breach, data loss or other security incident), dealing with sectors that are not well perceived by the public (such as weapons industries or embargoed countries), dealing with customers in sanctions lists, rating downgrades, significant variations in our share price over time, compliance failures, unethical behavior, actual or alleged improper conduct in areas such as lending, sales, marketing, corporate governance or culture, and the activities of customers and counterparties, including activities that negatively affect the environment. Our reputation could also suffer if we are the subject of negative coverage in the media, whether it has merit or not.

Actions by the financial services industry generally or by certain members of, or individuals in, the industry can also affect our reputation. For example, the role played by financial services firms in the financial crisis and the resulting shift toward increasing regulatory supervision and enforcement have led to a decline in public perception of us and others in the financial services industry.

Additionally, we could suffer significant reputational harm from negative perceptions regarding our approach to environmental, social and corporate governance policies. There has been increased focus by customers, shareholders, investor advocacy groups, employees, regulators and other stakeholders on these topics, and our policies, practices and disclosures in these areas could come under scrutiny. Governments may implement new or additional regulations and standards or investors, customers and other stakeholders may impose new expectations or focus investments in ways that cause significant shifts in disclosure, consumption and behaviors that may have negative impacts on our reputation and business. If regulators or stakeholders consider our efforts ineffective, inadequate or unsatisfactory, whether real or perceived, it could harm our reputation, business and prospects and we could be subject to enforcement or other supervisory actions.

We could also suffer significant reputational harm if we fail to identify and manage potential conflicts of interest properly, including conflicts of interests involving our directors and executive officers. The failure, or perceived failure, to adequately address conflicts of interest could affect the willingness of clients to deal with us, or could result in litigation or enforcement actions against us, which could have an adverse effect on our operating results, financial condition and prospects.

We may be the subject of misinformation and misrepresentations deliberately propagated in media or social media to harm our reputation or for other deceitful purposes, including by short sellers seeking to profit by spreading false or misleading information about us. There can be no assurance that we will effectively neutralize and contain any false information that may be propagated regarding us, which could have an adverse effect on our operating results, financial condition and prospects.

***We plan to continue to expand our operations and we may not be able to manage such growth effectively, or to execute successfully any of our strategic actions, which could have an adverse impact on us, including on our profitability. We may also not be successful in any reorganizations, dispositions or spin-offs we undertake.***

We allocate management and planning resources to develop strategic plans, priorities, policies and targets, including for organic growth and to identify potential acquisitions, divestitures and areas for restructuring our businesses. The execution of these initiatives is subject not only to external factors but also to our own decisions, including those that alter or redefine our business practices, operational frameworks, strategic objectives, corporate priorities, internal policies, and procedural guidelines.

*[**Table of Contents**](#toc)*<br>

We cannot provide assurance that we will, in all cases, be able to deliver our strategic plans, priorities, policies and targets. Furthermore, in order to grow and remain competitive, we will need to adapt to changes to meet the demands and expectations of regulators, our clients, shareholders and other stakeholders, including in relation to matters of public policy, regardless of whether there is a legal requirement to do so. We cannot guarantee that we will be able to implement changes to any of our strategic plans, priorities, policies and targets, in a timely and appropriate manner, or that we will be able to accurately predict trends, initiatives and business practices of financial institutions. It is also possible that regulators, our clients, shareholders and other stakeholders might not be satisfied or even disagree with our strategic plans, priorities, policies and targets, or the speed of their adoption, implementation, evolution and consequences.

From time to time, we evaluate acquisition, partnership, divestiture and other strategic opportunities that we believe offer additional value to our shareholders and are consistent with our business strategy. However, we may not be able to identify suitable acquisition, partnership, divestiture or other strategic candidates. Additionally, we may be unable to complete ongoing or future acquisitions, partnerships, divestitures or other strategic transactions in a timely or cost-effective manner, on the originally announced terms, or at all.

Even if we successfully complete any such transactions, we may not be able to successfully realize the expected results, benefits or synergies in a timely manner or at all. These results, benefits or synergies could also be adversely affected by acquisition- or divestiture-related charges and contingencies. In particular, our ability to benefit from any acquisitions and partnerships will depend in part on our successful integration of those businesses. Any such integration entails significant risks such as unforeseen difficulties in integrating operations and systems, unexpected liabilities or contingencies relating to the acquired businesses, including legal claims and delivery and execution risks. We can give no assurance that our expectations with regards to integration and synergies will materialize. In addition, any acquisition or venture could result in inconsistencies in standards, controls, procedures and policies. Moreover, the success of any acquisition or venture will, at least in part, be subject to a number of political, economic and other factors that are beyond our control. Any of these factors, individually or collectively, could have a material adverse effect on us.

We may also be subject to litigation in connection with, or as a result of, any such transactions, including claims from terminated employees, customers, suppliers or third parties. For example, we may be held responsible for the activities of an acquired business in the case of an acquisition. This includes liability for actions or non-compliance of an acquired business prior to its acquisition or in connection with its acquisition or integration. In the case of a divestiture, we may be required to indemnify the buyer for certain liabilities, including for uncapped amounts, in connection with claims against the divested entity or business.

Completion and integration of any such transactions may also divert management attention from other matters, result in additional costs and expenses or adversely affect our relationships with our customers, suppliers, employees and any other third parties, any of which may adversely affect our business or results of operations.

The challenges that may arise from our decisions include:

&nbsp;&nbsp;&nbsp;&nbsp;• managing efficiently the operations and employees of expanding businesses;

&nbsp;&nbsp;&nbsp;&nbsp;• maintaining or growing our existing customer base;

&nbsp;&nbsp;&nbsp;&nbsp;• assessing the value, strengths and weaknesses of investment or acquisition candidates, including local
regulations that could reduce or eliminate expected synergies;

&nbsp;&nbsp;&nbsp;&nbsp;• financing strategic investments or acquisitions;

&nbsp;&nbsp;&nbsp;&nbsp;• aligning our current information technology systems adequately with those of an enlarged group;

&nbsp;&nbsp;&nbsp;&nbsp;• applying our risk management policy effectively to an enlarged group;

&nbsp;&nbsp;&nbsp;&nbsp;• managing a growing number of entities without over-committing management or losing key personnel; and

&nbsp;&nbsp;&nbsp;&nbsp;• meeting the expectations of regulators and our clients, shareholders and other stakeholders.

*[**Table of Contents**](#toc)*<br>

Any failure to manage growth effectively, an inability to successfully adapt to changing conditions or to execute successfully any of our strategic actions, or any changes in our business practices, operational framework, strategic objectives, corporate priorities, internal policies and procedural guidelines could have a material adverse effect on our operating results, financial condition and prospects.

***Goodwill impairments may be required in relation to acquired businesses.***

We have made business acquisitions in recent years and may make further acquisitions in the future. It is possible that the goodwill that has been attributed, or may be attributed, to these businesses may have to be written down if our valuation assumptions are reassessed as a result of any deterioration in their underlying profitability, asset quality or other relevant matters. Impairment testing of goodwill is performed annually, or more frequently if there are impairment indicators present, and involves a comparison of the carrying amount of the cash-generating unit with its recoverable amount. Goodwill impairment does not, however, affect our regulatory capital. There can be no assurances that we will not have to write down the value attributed to goodwill in the future, which would adversely affect our results and net assets.

***We rely on recruiting, retaining and developing appropriate senior management and skilled personnel.***

The continuity of our success depends partly on the retention of key members of our senior executive team and other employees who are critical to the business. The ability to attract, develop, motivate, and retain highly qualified professionals is essential to the execution of our strategy. The successful implementation of our strategy and culture depends on the availability of skilled and appropriate management, both at our head office and in each of our business units. If we or one of our business units or other functions do not adequately staff operations or do not retain one or more key senior executives or other key employees and fail to replace them promptly and effectively, our business, financial condition and results of operations, including control and operational risks, may be adversely affected.

Our ability to attract and retain qualified employees depends on perceptions of our culture, social and corporate governance policies and management, our profile in the markets in which we operate and the professional opportunities we offer.

In addition, the financial industry faces, and may continue to face, more stringent regulation of employee compensation, which could have an adverse effect on our ability to hire or retain the most qualified employees. If we do not attract and appropriately train, motivate and retain qualified professionals, our business may be adversely affected.

***We rely on third parties and affiliates for important products and services.***

Third-party vendors and certain affiliated companies provide key components of our business infrastructure such as loan and deposit servicing systems, back office and business process support, information technology production and support, internet connections, and network access (including cloud-based services). Relying on these third parties and affiliated companies can be a source of operational and regulatory risk to us, including with respect to security breaches, service outages and other disruptions or failures affecting such parties. We are also subject to risk with respect to security breaches, service outages and other disruptions or failures affecting the vendors and other parties that interact with these service providers. As our interconnectivity with these third parties and affiliated companies increases, we face the risk of operational failure with respect to their systems. We may be required to take steps to protect the integrity of our operational systems, thereby increasing our operational costs. In addition, certain problems caused by these third parties or affiliated companies could affect our ability to deliver products and services to customers. While we have diversified providers for the main services and keep strict and close monitoring on them, in some instances, replacing these third-party vendors could also entail delays and expense. Further, the operational and regulatory risk we face as a result of these arrangements may be increased to the extent that we restructure such arrangements. Restructurings could involve significant expense to us and entail significant delivery and execution risk, which could have a material adverse effect on our business, operations and financial condition.

***Past performance of our loan portfolio may not be indicative of future performance; changes in the profile of our business may adversely affect our loan portfolio. In addition, the value of any collateral securing our loans may not be sufficient, and we may be unable to realize the full value of the collateral securing our loan portfolio.***

Our historical loan loss experience may not be indicative of our future loan losses. While the quality of our loan portfolio is associated with the default risk in the sectors in which we operate, changes in our business profile may occur due to, among other factors, our organic growth, merger and acquisition activity, changes in local economic and political conditions, a slowdown in customer demand, an increase in market competition, changes in regulation and in the tax regimes applicable to the sectors in which we operate and, to a lesser extent, other related changes in countries in which we operate and in the international economic environment. In addition, the market value of any collateral related to our loan portfolio may fluctuate, from the time we evaluate it at the beginning of the trade to the time such collateral can be executed upon, due to the factors related to changes in economic, political or sectorial factors beyond our control, and we may be unable to realize the full value of the collateral securing our loan portfolio.

*[**Table of Contents**](#toc)*<br>

***We rely on models for many of our decisions. Their inaccurate or incorrect use could have a material adverse effect on us.***

We use models for (i) admission (scoring and rating) and behavioral credit processes, (ii) the definition of credit limits, and (iii) the calculation of capital and provisions, and of market and structural, operational, compliance and liquidity risks, among others. A model is a system, approach or quantitative method that applies statistical, economic, financial or mathematical theories, techniques or hypotheses to transform input data into quantitative estimates and forecasts. It involves simplified representations of real-world relationships between characteristics, values and observed assumptions that allow us to focus on specific aspects.

Model risk is the negative consequence of decisions based on inaccurate, improper or incorrect use of models. Sources of model risk include (i) incorrect or incomplete data in the model itself or the modelling method used in systems and (ii) incorrect use or implementation of the model. We manage model risk on a consolidated basis with the Santander Group, which includes internal model risk policies and a tiering mechanism to categorize the levels of importance of non-regulatory models and model risk management.

Nonetheless, model risk can cause financial loss, erroneous commercial and strategic decision-making or damage to our transactions, any of which could have a material adverse effect on our operating results, financial condition and prospects. In addition, our regulatory models and the underlying methodologies are subject to scrutiny from our supervisors, who could identify potential weaknesses or deficiencies that may result in enforcement actions, including sanctions, fines and/or the imposition of stricter capital requirements, as well as mandates and recommendations with respect to the methodologies underlying our models, which could also lead to more onerous or inefficient capital consumption.

Additionally, changes in economic and market drivers impact the performance of financial models, including credit loss and provisions models, capital models, traded risk models and models used in the asset/liability management process. This requires additional monitoring and adjustments to comply with the guidance and recommendations of standard setters, regulators and supervisors, particularly for credit loss models. It also results in the use of mitigants for model limitations, such as adjustments to model outputs to reflect consideration of management judgment. The performance and usage of models has been and may continue to be impacted by the consequences of changes in economic and market drivers, such as geopolitical events, financial crises, social and political upheaval and other events. While it is too early to be entirely certain of the magnitude of change required for our models, it is likely that capital, credit risk and other models will need to be adjusted.

In addition, the fair value of our financial assets, determined using financial valuation models, may be inaccurate or subject to change and, as a consequence, we may have to register impairments or write-downs that could have a material adverse effect on our operating results, financial condition and prospects. See "—Market conditions have resulted and could result in material changes to the estimated fair values of our financial assets. Negative fair value adjustments could have a material adverse effect on our operating results, financial condition and prospects."

***Climate change can create transition risks, physical risks and other risks that could adversely affect us.***

Risks associated with climate change are gaining increasing social, regulatory, economic and political relevance in Brazil and globally. New climate-related regulations may affect our operations and business strategy and lead us to incorporate financial costs resulting from the following risk drivers:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Transition risks associated with the shift to a low-carbon economy may arise from changes in legislation, regulatory and supervisory expectations, public policies, technological developments and evolving market and consumer preferences. These developments may increase our operating costs, affect the viability of certain activities and require adjustments to our business practices and risk-management processes, which could adversely affect our business, financial condition and results of operations. As a result, we expect greater scrutiny of our business and of the customers with whom we transact. Our operational decision-making in industries or projects associated with causing or exacerbating climate change may also be affected as we seek to adapt our practices to avoid reputational or client-relationship impacts, which may influence customer demand, returns on certain activities and the value of certain assets and trading positions. Recent regulatory developments that may affect our operations and those of our customers include EU Regulation 2023/1115 on deforestation-free products and Brazil's Law No. 15,042/2024, which created the Brazilian Greenhouse Gas Emissions Trading System. In addition, the expanding global regulatory agenda—including the EU's Corporate Sustainability Reporting Directive and ongoing updates to Brazilian regulatory expectations on climate-risk management and disclosure—is increasing compliance requirements and data-quality demands. These changes may raise operational costs for clients, alter market-access conditions and require enhanced due-diligence and risk-management processes across our portfolios.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Physical risks related to events such as flooding and wildfires, and to long-term shifts in climate patterns such as extreme heat, sea-level rise and prolonged droughts, may result in financial losses that impair asset values and the creditworthiness of our customers. Brazil, for example, experienced severe weather events in 2024 and 2025, such events can disrupt our operations or those of our customers or third parties on which we rely, through direct damage to assets and indirect effects stemming from supply-chain disruptions and market volatility.

We may not be able to fully anticipate or mitigate all potential impacts arising from climate-related events. To the extent we are unable to effectively embed climate-related risks into our risk and operational frameworks, or to adequately adjust our strategy and business model in response to evolving regulatory, market and environmental conditions, we may face limitations in our ability to appropriately identify, measure, manage and disclose such risks. Any such limitations could adversely affect our business, financial condition and results of operations and might increase our susceptibility to the risks described below.

These primary drivers could materialize, among others, in the following risks:

&nbsp;&nbsp;&nbsp;&nbsp;• **Credit risks:** Physical climate change could lower corporate revenues, increase operating costs
and lead to increased credit exposure. Severe weather could also affect collateral values. Companies whose business models are not aligned
with the transition to a low-carbon economy may also face a higher risk of reduced earnings and business disruption due to regulatory
or market shifts.

&nbsp;&nbsp;&nbsp;&nbsp;• **Market risks:** Market changes in carbon-intensive sectors could affect energy and commodity prices,
corporate bonds, equities and derivatives. The increasing frequency of severe weather events could weaken macroeconomic fundamentals such
as growth, employment and inflation, and lead to higher volatility.

&nbsp;&nbsp;&nbsp;&nbsp;• **Liquidity risks:** Companies may face liquidity pressures due to cash outflows required to address
climate-related challenges or reputational concerns. Extreme weather events may also affect the value of our high-quality liquid assets
or increase sovereign debt levels, potentially limiting our access to capital markets.

&nbsp;&nbsp;&nbsp;&nbsp;• **Operational risks:** Severe weather events could damage assets and disrupt the business continuity
of our customers or our own operations. Climate-related financial risks could also give rise to litigation, for example if we are perceived
to misrepresent sustainability-related practices, achievements, metrics, goals or targets.

&nbsp;&nbsp;&nbsp;&nbsp;• **Regulatory compliance risks:** Climate-related regulatory compliance risks may increase due to
the rising pace and breadth of new requirements across multiple jurisdictions and shifts in public policy, laws and regulations related
to climate-change and environmental-sustainability matters.

&nbsp;&nbsp;&nbsp;&nbsp;• **Reputational risks:** Our reputation and client relationships may be harmed as a result of our
practices, disclosures or decisions related to climate-change or social and environmental issues, or due to the practices of our clients,
vendors or suppliers. We could also face conduct risks arising from misrepresentations in sustainability-related disclosures, including
our practices, achievements, metrics, goals or targets, or those of our products or customers.

&nbsp;&nbsp;&nbsp;&nbsp;• **Strategic risks:** Our strategy could be adversely affected if we fail to achieve our targets,
including those related to the activities that we finance and those concerning our own operations.

As a financial institution, we are subject to regulatory sustainability requirements, as detailed under "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Sustainability Requirements Applicable to Financial Institutions." These requirements may increase as sustainability matters gain prominence. Such changes may raise compliance costs and limit our ability to pursue certain business opportunities or provide certain products and services, which could adversely affect our business, financial condition and results of operations.

*[**Table of Contents**](#toc)*<br>

As climate risk is interconnected with all key risk types, we have developed and continue to enhance processes to embed climate risk considerations into our risk management strategies; however, because the timing and severity of climate change remain uncertain and continue to evolve rapidly, our risk management strategies may not be effective in mitigating climate risk exposure.

We periodically disclose information such as emissions and other climate-related performance data, statistics, metrics and targets. If we lack robust and high-quality procedures, controls or data, we may be unable to disclose reliable climate-related information. In addition, because such climate-related information is based on current expectations and future estimates about our and third-parties' operations and businesses and addresses matters that are uncertain to varying degrees, we may not be able to meet our estimates and targets or we may not be able to achieve them within the timelines we announce. Actual or perceived shortcomings with respect to these emissions and other climate-related initiatives and reporting could result in litigation or regulatory enforcement and impact our ability to hire and retain employees, increase our customer base, and attract and retain certain types of investors.

Our exposure to sectors most affected by climate factors—identified through market consensus and the materiality analysis we conduct—primarily involves corporate and investment banking portfolios. The management of these clients incorporates, where appropriate and permissible, climate considerations during initial analysis, credit granting, and the preparation and review of credit ratings. These ratings influence parameters used to calculate credit losses, such as probability of default. Consequently, if climate factors are significant, they are integrated with other analytical elements into credit loss calculations, informing capital and provisioning requirements.

Initiatives and business practices of financial institutions with respect to climate matters and other matters of public policy, including ESG matters, have recently become the subject of significant scrutiny by regulatory agencies and government officials. In particular, there are a growing number of regulatory initiatives in certain jurisdictions aimed at discouraging or limiting the consideration of ESG factors by financial institutions, as well as proceedings asserting that consideration of ESG factors by financial institutions conflict with certain regulatory requirements or the expectations of their clients, shareholders and other stakeholders. Such differing, sometimes conflicting, views and regulations on sustainability and ESG-related matters increase the risk that certain of our actions, or lack of action, on such matters will be perceived negatively or result in scrutiny by regulators or legal proceedings. Additionally, the overall expectations of regulators and our clients, shareholders and other stakeholders in certain jurisdictions, particularly in Europe, with respect to certain of these issues may differ significantly from those in other jurisdictions, such as the United States.

Furthermore, our relationships or ability to transact with clients and customers, and with governmental or regulatory bodies in certain jurisdictions could be adversely affected if our decisions with respect to doing business with companies in certain sensitive industries are perceived to harm those companies, result in violations of law or breaches of fiduciary duty or to align with particular ideological, political or social views. We are also exposed to associated risks of non-compliance with relevant legal requirements, including fines, penalties, litigation, regulatory sanctions, difficulties in obtaining governmental approvals, restrictions on our business activities or reputational damage, any of which could be material. Additionally, our participation in, or association with, certain groups or initiatives and our business practices or positions with respect to matters of public policy, including ESG matters, could be criticized by activists, governmental authorities and our clients, shareholders and other stakeholders.

Any of the conditions described above, or our failure to identify other climate-related risks, could have a material adverse effect on our business, financial condition and results of operations.

***Structural demographic shifts in Brazil could adversely affect our business, financial condition and results of operations.***

Structural demographic shifts in Brazil — including the rapid aging of the population, internal migration and urbanization patterns, and external migration flows (whether driven by geopolitical, economic or climate-related events), as well as changing household formation patterns — may alter local customer bases and labor markets, dampen demand for certain products (e.g., long-tenor mortgages), shift savings toward lower-margin solutions and require incremental service adaptations for senior or otherwise vulnerable customers. If we fail to adapt our products and channels accordingly, our revenues, costs and conduct and operational risk profile could be adversely affected.

The sustainability of Brazil's public and private pension systems — including reforms to retirement ages, contribution rates, benefits or tax treatment under Brazilian law — can materially influence our customers' disposable income, savings flows and creditworthiness. In addition, our own long-term employee benefit obligations are sensitive to financial and demographic assumptions (including longevity and discount rates). Generally, changes in assumptions could increase expenses or capital needs. Any of these factors could have a material adverse effect on our business, financial condition and results of operations.

*[**Table of Contents**](#toc)*<br>

***The outbreak of public health emergencies could materially and adversely impact our business, financial condition, liquidity and results of operations.***

The outbreak of public health emergencies may force countries to adopt measures, similar to those adopted in response to the Covid-19 pandemic, that restrict economic activity, which may deteriorate the macroeconomic environment and adversely impact our business and results of operations, including, among others (i) decreased demand for our products and services; (ii) further material impairment of our loans and other assets including goodwill; (iii) decline in the value of collateral; (iv) constraints on our liquidity due to market conditions, exchange rates and customer withdrawal of deposits and continued draws on lines of credit; (v) downgrades of our credit ratings; and (vi) operational disruptions, technology infrastructure failures, increased cybersecurity risks or governmental restrictions affecting our operations.

Situations of this nature may require expanded remote-work arrangements or limit in-person activities. If, in connection with any future public health emergencies, we become unable to successfully operate our business from remote locations including, for example, due to failures of our technology infrastructure, increased cybersecurity risks, or governmental restrictions that affect our operations, this could result in business disruptions that could have a material and adverse effect on our business.

Any such events could materially and adversely affect our business, financial condition, liquidity and results of operations.

**Risks Relating to Our Controlling Shareholder, Our Units and American Depositary Receipts (ADRs)**

***Our ultimate controlling shareholder has a great deal of influence over our business, and its interests could conflict with ours.***

As of January 31, 2026, Santander Spain, our ultimate controlling shareholder, currently owns, directly and indirectly, approximately 89.53% of our total capital.

Due to its share ownership, our controlling shareholder has the power to control us and our subsidiaries, including the power to:

&nbsp;&nbsp;&nbsp;&nbsp;• elect a majority of our directors that appoint our executive officers, set our management policies and
exercise overall control over our Company and subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;• influence the appointment of our principal officers;

&nbsp;&nbsp;&nbsp;&nbsp;• declare the payment of any dividends;

&nbsp;&nbsp;&nbsp;&nbsp;• agree to sell or otherwise transfer its controlling stake in our Company; and

&nbsp;&nbsp;&nbsp;&nbsp;• determine the outcome of substantially all actions requiring shareholder approval, including amendments
of our bylaws, transactions with related parties, corporate reorganizations, acquisitions and dispositions of assets, and dividends.

We operate as a standalone subsidiary within the Santander Group. Our controlling shareholder has no liability for our banking operations, except for the amount of its holdings of our capital stock and for other specific limited circumstances under Brazilian law. The interests of Santander Spain may differ from the interests of our other shareholders, and the concentration of control in Santander Spain will limit other shareholders' ability to influence corporate matters. As a result, we may take actions that our other shareholders do not view as beneficial.

***Our status as a controlled company and a foreign private issuer exempts us from certain of the corporate governance standards of the New York Stock Exchange, or "NYSE," limiting the protections afforded to investors.***

We are a "controlled company" and a "foreign private issuer" within the meaning of the NYSE corporate governance standards. Under the NYSE rules, a controlled company is exempt from certain NYSE corporate governance requirements. In addition, a foreign private issuer may elect to comply with the practice of its home country and not to comply with certain NYSE corporate governance requirements, including the requirements that (i) a majority of the board of directors consists of independent directors, (ii) a nominating and corporate governance committee be established that is composed entirely of independent directors and has a written charter addressing the committee's purpose and responsibilities, (iii) a compensation committee be established that is composed entirely of independent directors and has a written charter addressing the committee's purpose and responsibilities and (iv) an annual performance evaluation of the nominating and corporate governance and compensation committees be undertaken. Although we have similar practices, they do not entirely conform to the NYSE requirements; therefore, we currently use these exemptions and intend to continue using them. Accordingly, you will not have the same protections provided to shareholders of companies that are subject to all NYSE corporate governance requirements.

***The liquidity and market prices of the units and the ADRs may be adversely affected by the cancellation of units or substantial sale of units and shares in the market, or by the relative volatility and limited liquidity of the Brazilian securities markets.***

Holders of units may present these units or some of these units for cancellation in Brazil in exchange for the common shares and preferred shares underlying these units. If unit holders present a significant number of units for cancellation in exchange for the underlying common shares and preferred shares, the liquidity and price of the units and ADRs may be materially and adversely affected.

Also, sales of a substantial number of our units, common shares or preferred shares in the future, or the anticipation of such sales, could negatively affect the market prices of our units and ADRs. If, in the future, substantial sales of units, common shares or preferred shares are made by existing or future holders, the market prices of the ADRs may decrease significantly. As a result, holders of ADRs may not be able to sell their ADRs at or above the price they paid for them.

***The relative volatility and limited liquidity of the Brazilian securities markets may negatively affect the liquidity and market prices of the units and the ADRs.***

The B3 is significantly less liquid than the NYSE or other major exchanges in the world. As of December 31, 2025, the aggregate market capitalization of the B3 was equivalent to approximately R$4.8 trillion (U.S.$0.9 trillion), and the top 10 stocks in terms of trading volume accounted for approximately 45% of all shares traded on B3 in the year ended December 31, 2025. In contrast, as of December 31, 2025, the aggregate market capitalization of the NYSE was approximately U.S.$44.7 trillion. Although any of the outstanding shares of a listed company may trade on the B3, in most cases fewer than half of the listed shares are actually available for trading by the public, the remainder being held by small groups of controlling persons, government entities or a principal shareholder.

In 2024 and 2025, volatility was driven by extreme weather events in Brazil, including droughts and floods linked to the El Niño phenomenon, which impacted key sectors of the economy, as well as renewed geopolitical tensions and the effects of persistent inflationary pressures. The resulting disruptions to agricultural output, energy generation and transportation infrastructure contributed to increased price volatility, pressured supply chains and heightened uncertainty regarding Brazil's short-term growth prospects. These factors, along with uncertainty surrounding Brazil's fiscal policies and global monetary tightening cycles, have contributed to fluctuations in the prices of our securities traded on the NYSE and the B3. We cannot assure you that the price of our securities will not fall below the lowest levels at which they traded in the past as a result of these or other factors.

The relative volatility and limited liquidity of the Brazilian securities markets may substantially limit your ability to sell the units or ADRs at the time and price you desire and, as a result, could negatively impact the market price of these securities.

***If securities analysts do not publish research or reports about our business or if they downgrade our ADRs or securities issued by other companies in our sector, the price and trading volume of our ADRs and/or our shares could decline.***

The trading market for our ADRs and our shares has been affected in part by the research and reports that industry and financial analysts publish about us or our business. We do not control these analysts' reports and opinions. Furthermore, if one or more of the analysts downgrade our ADRs, our shares or our industry, change their views regarding the shares of any of our competitors, or other companies in our sector, or publish inaccurate or unfavorable research about our business, the market price of our ADRs and/or shares could decline. If one or more of these analysts stops providing reports or fails to publish reports on us regularly, we could lose visibility in the market, which in turn could cause our ADR and/or share price or trading volume to decline.

*[**Table of Contents**](#toc)*<br>

***The economic value of your investment may be diluted.***

We may, from time to time, need additional funds, and we may issue additional units or shares. Any additional funds obtained by such a capital increase may dilute your interest in our Company or decrease the market price of our shares, units or ADRs.

***Discontinuation of the current corporate governance practices may negatively affect the price of our ADRs and units.***

After completion of the voluntary exchange offers by Santander Spain in Brazil and in the United States for the acquisition of up to all of our shares that were not held by the Santander Group at that time, we are no longer subject to the obligations of the special listing segment of B3 known as the Level 2 corporate governance segment (the "Level 2 Segment"). For more information, see "Item 9. The Offer and Listing—C. Markets—Corporate Governance Practices." Currently, we voluntarily comply with certain of the corporate governance requirements for companies listed on the Level 2 Segment.

Discontinuation, in whole or in part, of our existing corporate governance practices or minimum protections may adversely affect your rights as a security holder and may result in a decrease in the price of our shares, units and ADRs.

***Holders of our units and our ADRs may not receive any dividends or interest on stockholders' equity.***

According to our By-Laws, we must generally pay our shareholders at least 25% of our annual net income as dividends or interest on stockholders' equity, as calculated and adjusted under Brazilian Corporate Law, or "adjusted net income," which may differ significantly from our net income as determined under IFRS. This adjusted net income may be used to increase capital or to absorb losses, or otherwise retained as allowed under Brazilian Corporate Law, and may not be available to be paid as dividends or interest on stockholders' equity. Additionally, Brazilian Corporate Law allows a publicly traded company, like ours, to suspend the mandatory distribution of dividends and interest on stockholders' equity in any particular year if our board of directors informs our shareholders that such distributions would be inadvisable in view of our financial condition or cash availability. We paid R$7.6 billion, R$6.0 billion and R$6.2 billion (R$2.04, R$1.61 and R$1.67 per unit, respectively) as dividends and interest on stockholders' equity (considering gross value) in 2025, 2024 and 2023, respectively, in accordance with our dividend policy, but there can be no assurance that dividends and interest on stockholders' equity will be paid in the future. In the future, we may also become subject to Brazilian banking regulations that may limit the payment of dividends or interest on stockholders' equity, such as a temporary restriction in 2020 on dividend distributions and other payments as a result of measures taken by the Brazilian Central Bank to combat the COVID-19 pandemic's effect on the Brazilian financial sector. Although this restriction was not reinstated in the years that followed, we cannot assure you that this or other restrictions will not be reinstated in the future.

***Holders of ADRs may find it difficult to exercise voting rights at our shareholders' meetings.***

Holders of ADRs are not our direct shareholders and are unable to enforce directly the rights of shareholders under our By-Laws and Brazilian Corporate Law. Holders of ADRs may exercise voting rights with respect to the units represented by ADRs only in accordance with the deposit agreement governing the ADRs. Holders of ADRs face practical limitations in exercising their voting rights because of the additional steps involved in our communications with ADR holders. For example, we are required to publish a notice of our shareholders' meetings in specified newspapers in Brazil. Holders of our units will be able to exercise their voting rights by attending a shareholders' meeting in person or voting by proxy. By contrast, holders of ADRs will receive notice of a shareholders' meeting by mail from the ADRs depositary following our notice to the depositary requesting the depositary to do so. To exercise their voting rights, holders of ADRs must instruct the ADR depositary on a timely basis on how they wish to vote. This voting process necessarily will take longer for holders of ADRs than for holders of our units or shares. If the ADR depositary fails to receive timely voting instructions for all or part of the ADRs, the depositary will assume that the holders of those ADRs are instructing it to give a discretionary proxy to a person designated by us to vote their ADRs, except in limited circumstances.

Holders of ADRs also may not receive the voting materials in time to instruct the depositary to vote the units underlying their ADRs. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions of the holders of ADRs or for the manner of carrying out those voting instructions. Accordingly, holders of ADRs may not be able to exercise voting rights, and they will have little, if any, recourse if the units underlying their ADRs are not voted as requested.

*[**Table of Contents**](#toc)*<br>

***Holders of ADRs could be subject to Brazilian income tax on capital gains from sales of ADRs.***

Law No. 10,833 of December 29, 2003 provides that the disposal of assets located in Brazil by a nonresident to either a Brazilian resident or a nonresident is subject to taxation in Brazil, regardless of whether the disposal occurs outside or within Brazil. This provision results in the imposition of income tax on the gains arising from a disposal of our units by a nonresident of Brazil to another nonresident of Brazil. It is unclear whether ADRs representing our units, which are issued by the ADR depositary outside Brazil, will be deemed to be "property located in Brazil" for purposes of this law. We believe that ADRs do not qualify as property located in Brazil and, thus, should not be subject to Brazilian income tax. Nevertheless, there is no judicial guidance as to the application of Law No. 10,833 of December 29, 2003 and, accordingly, we are unable to predict whether Brazilian courts may decide that it applies to dispositions of our ADRs between nonresidents of Brazil. However, in the event that the disposition of assets is interpreted to include a disposition of our ADRs, this tax law would accordingly impose withholding taxes on the disposition of our ADRs by a nonresident of Brazil to another nonresident of Brazil. See "Item 10. Additional Information—E. Taxation—Brazilian Tax Considerations."

Any gain or loss recognized by a U.S. taxpayer will generally be treated as U.S. source gain or loss. A U.S. taxpayer would generally not be able to credit any Brazilian tax imposed on the disposition of our units or ADRs against such person's U.S. federal income tax liability. See "Item 10. Additional Information—E. Taxation—Material U.S. Federal Income Tax Considerations for U.S. Holders.

***Our corporate disclosure may differ from disclosure regularly published by issuers of securities in other countries, including the United States.***

Issuers of securities in Brazil are required to make public disclosures that are different from, and that may be reported under presentations that are not consistent with, disclosures required in other countries, including the United States. In particular, for regulatory purposes, we currently prepare and will continue to prepare and make available to our shareholders statutory financial statements in accordance with IFRS as issued by the IASB and Brazilian GAAP, both of which differ from U.S. GAAP in a number of respects. In addition, as a foreign private issuer, we are not subject to the same disclosure requirements in the United States as a domestic U.S. registrant under the Exchange Act, including the requirements to prepare and issue quarterly reports, the proxy rules applicable to domestic U.S. registrants under Section 14 of the Exchange Act or the insider reporting and short-swing profit rules under Section 16 of the Exchange Act. Accordingly, the information about us available to investors will not be the same as the information available to shareholders of a U.S. company and may be reported in a manner with which some investors may not be familiar.

***Investors may find it difficult to enforce civil liabilities against us or our directors and officers.***

The majority of our directors and officers reside outside the United States. In addition, all or a substantial portion of our assets and the assets of our directors and officers are located outside the United States. Although we have appointed an agent for service of process in any action against us in the United States with respect to our ADRs, none of our directors or officers has consented to service of process in the United States or to the jurisdiction of any U.S. court. As a result, it may not be possible for holders of our shares, units and/or ADRs to effect service of process against these other persons within the United States or other jurisdictions outside Brazil or to enforce against these other persons judgments obtained in the United States or other jurisdictions outside Brazil. Holders of our ADRs may face greater difficulties in protecting their interests due to actions by us or our directors or executive officers than would shareholders of a U.S. corporation, because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if the judgment meets the following conditions: (i) it must comply with the formalities necessary for enforcement under the laws of the jurisdiction in which it was rendered; (ii) it must have been issued by a competent jurisdiction/court after proper service of process on the parties, which service must comply with Brazilian law if made in Brazil, or after sufficient evidence of the parties' absence (*revelia*) has been given, as required by applicable law; (iii) it must be final, binding and therefore not subject to appeal (*res judicata*) in the jurisdiction in which it was issued; (iv) it must be apostilled by a competent authority of the country from which the document emanates according to the Hague Convention of 5 October 1961 Abolishing the Requirement of Legalization for Foreign Public Documents or, if such country is not signatory of the Hague Convention, it must be duly authenticated by a competent Brazilian consulate in the country where the foreign judgment is issued; (v) it must be accompanied by a translation thereof into Portuguese made by a certified translator in Brazil, unless an exemption is provided by an international treaty to which Brazil is a signatory; (vi) it must not be contrary to Brazilian national sovereignty, good morals or public policy or violate the dignity of the human person (as set forth in Brazilian law); (vii) it must not relate to a matter which is also subject to a similar proceeding in Brazil involving the same parties, based on the same grounds and with the same object, which has already been judged by a Brazilian court (*res judicata*); and (viii) it must not violate the exclusive jurisdiction of Brazilian courts pursuant to the provision of Article 23 of the Brazilian Code of Civil Procedure (Law No. 13,105/2015). Judgments which meet these criteria are not subject to an analysis of the merits or a retrial by Brazilian courts.

*[**Table of Contents**](#toc)*<br>

***Judgments of Brazilian courts with respect to our units or ADRs will be payable only in reais.***

Our By-Laws provide that we, our shareholders, our directors and officers and the members of our fiscal council (if installed) shall submit to arbitration any and all disputes or controversies that may arise among ourselves relating to, or originating from, the application, validity, effectiveness, interpretation, violations and effects of violations of the provisions of Brazilian Corporate Law, our By-Laws, the rules and regulations of the CMN, the Brazilian Central Bank and the CVM, as well as other rules and regulations applicable to the Brazilian capital markets and the rules and regulations of the Arbitration Regulation of the Market Arbitration Chamber. However, in specific situations, including whenever precautionary motions are needed for protection of rights, the dispute or controversy may have to be brought to a Brazilian court. If proceedings are brought in the courts of Brazil seeking to enforce our obligations in respect of the units or ADRs, we will not be required to discharge our obligations in a currency other than *reais*. Under Brazilian exchange control limitations and according to Brazilian laws, an obligation in Brazil to pay amounts denominated in a currency other than *reais* may be satisfied in Brazilian currency only at the exchange rate, as determined by the Brazilian Central Bank or competent court, in effect on the date the judgment is obtained, and such amounts are then adjusted to reflect exchange rate variations through the effective payment date. The then-prevailing exchange rate may not afford non-Brazilian investors with full compensation for any claim arising out of or related to our obligations under the units or ADRs.

***Holders of ADRs may be unable to exercise preemptive rights with respect to our units underlying the ADRs.***

Holders of ADRs will be unable to exercise the preemptive rights relating to our units underlying ADRs unless a registration statement under the Securities Act is effective with respect to the shares for which those rights are exercisable or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement with respect to the shares relating to these preemptive rights or to take any other action to make preemptive rights available to holders of units or ADRs. We may decide, at our discretion, not to file any such registration statement. If we do not file a registration statement or if we and the ADR depositary decide not to make preemptive rights available to holders of units or ADRs, those holders may receive only the net proceeds from the sale of their preemptive rights by the depositary, or if they are not sold, their preemptive rights will be allowed to lapse.

***Holders of ADRs have different shareholders' rights than do shareholders of companies incorporated in the United States and certain other jurisdictions.***

Our corporate affairs are governed by our By-Laws and by Brazilian Corporate Law, which may differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States or in certain other jurisdictions outside Brazil.

Under Brazilian Corporate Law, holders of the ADRs are not our direct shareholders and have to exercise their voting rights through the depositary. Therefore, holders of ADRs may have fewer and less well-defined rights to protect their interests relative to actions taken by our board of directors or the holders of our common shares under Brazilian law than under the laws of other jurisdictions outside Brazil.

Although Brazilian Corporate Law imposes restrictions on insider trading and price manipulation, the form of these regulations and the manner of their enforcement may differ from that in the U.S. securities markets or markets in certain other jurisdictions. In addition, in Brazil, self-dealing and the preservation of shareholder interests may be regulated differently, which could potentially disadvantage you as a holder of the preferred shares underlying ADRs.

***Holders of ADRs who exchange ADRs for their underlying units may risk losing Brazilian tax advantages and the ability to remit foreign currency abroad.***

Brazilian law requires that parties obtain registration with the Brazilian Central Bank in order to remit foreign currencies, including U.S. dollars, abroad. The Brazilian custodian for the units must obtain the necessary registration with the Brazilian Central Bank for payment of dividends or other cash distributions relating to the units or after disposal of the units. If you exchange your ADRs for the underlying units, however, you may only rely on the custodian's certificate for five business days from the date of exchange. Thereafter, you must obtain your own registration in accordance with the rules of the Brazilian Central Bank and the CVM, in order to obtain and remit U.S. dollars abroad after the disposal of the units or the receipt of distributions relating to the units. If you do not obtain a certificate of registration, you may not be able to remit U.S. dollars or other currencies abroad and may be subject to less favorable tax treatment on gains with respect to the units. For more information, see "Item 10. Additional Information—D. Exchange Controls."

If you attempt to obtain your own registration, you may incur expenses or suffer delays in the application process, which could delay your receipt of dividends or distributions relating to the units or the return of your capital in a timely manner. The custodian's registration and any certificate of foreign capital registration you may obtain may be affected by future legislative changes. Additional restrictions applicable to you, to the disposal of the underlying units or to the repatriation of the proceeds from disposal may be imposed in the future.

*[**Table of Contents**](#toc)*<br>

***Holders of the ADRs may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could be less favorable or less desirable to the plaintiff(s) in any such action.***

The deposit agreement provides that, to the extent permitted by law, holders of the ADRs waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our shares, the ADRs or the deposit agreement. The deposit agreement, including the waiver of the right to jury trial, governs the rights of the initial holders of the ADRs as well as the rights of subsequent holders that acquire holders of the ADRs in the secondary market.

If any holders or beneficial owners of the holders of the ADRs bring a claim against us or the depositary in connection with matters arising under the deposit agreement or the ADRs, such holder or beneficial owner may not be entitled to a jury trial with respect to such claims, which may have the effect of limiting and discouraging lawsuits against us and/or the depositary. Any plaintiff(s) in such an action may believe that a nonjury trial would be less favorable to the plaintiff(s) or otherwise less desirable.

**History**

We are currently the third largest privately owned bank in Brazil, and the only international bank that operates countrywide. We operate in both the retail and wholesale segments with high-added value offers, which allows us to provide our products and services to individuals, small and medium enterprises, and large corporate customers.

We are part of the Santander Group, a financial institution founded in Spain in 1857, and that has expanded globally through numerous acquisitions. Under the Santander Group's business model, each major unit is autonomous and self-sufficient in terms of capital and liquidity. However, our relationship with the Santander Group allows us to:

&nbsp;&nbsp;&nbsp;&nbsp;• access the Santander Group's global operation network, using the operational synergies with the
Santander Group to enhance our ability to provide global products and services to our customers, while reducing technology development
costs;

&nbsp;&nbsp;&nbsp;&nbsp;• provide our customers with the benefits of a strong presence in certain international markets, predominantly
in Latin America and Western Europe;

&nbsp;&nbsp;&nbsp;&nbsp;• assimilate best practices with respect to products, services, internal controls and risk management
that were implemented by the Santander Group internationally; and

&nbsp;&nbsp;&nbsp;&nbsp;• develop our employees' skills by means of local and international training and development initiatives,
including international experiences at the Santander Group's offices worldwide.

Our history in the Brazilian banking industry goes back to the 1970s and is summarized in the following figure:

![](image_007.jpg)

**Santander Brasil Timeline**

In 1957, the Santander Group entered the Brazilian market for the first time through an operating agreement with Banco Intercontinental do Brasil S.A. In 1970, the Santander Group opened a representative office in Brazil, followed by its first branch in 1982.

Since the 1990s, the Santander Group established its presence in Latin America, particularly in Brazil, by capitalizing on organic growth and pursuing an acquisition strategy, including the following most notable acquisitions:

&nbsp;&nbsp;&nbsp;&nbsp;• In November 2000, the Santander Group acquired Banespa, a bank owned by the State of São Paulo
which resulted in the Santander Group becoming one of Brazil's largest financial groups.

&nbsp;&nbsp;&nbsp;&nbsp;• On July 24, 2008, Santander Spain took an indirect share control of Banco ABN AMRO Real S.A. and ABN
AMRO Brasil Dois Participações S.A. and their respective consolidated subsidiaries in 2008, or "Banco Real,"
which was then absorbed into the Santander Group in order to further consolidate its investments in Brazil. Santander Brasil's acquisition
of Banco Real's share capital was approved through a share exchange transaction on August 29, 2008, which resulted in Banco Real
becoming a wholly owned subsidiary of Santander Brasil. Subsequently, it was merged into Santander Brasil on April 30, 2009.

Since October 7, 2009, our units and common and preferred shares have been listed and traded on B3 under the symbols "SANB11," "SANB3" and "SANB4," respectively. Our ADRs have been registered with the SEC under the Securities Act and are listed and traded on the NYSE under the symbol "BSBR." For further information, see "Item 9. The Offer and Listing—A. Offering and Listing Details."

**Important Events**

We have set forth below important recent events in the development of our business. For further information, please see note 11 (d) to our audited consolidated financial statements, included elsewhere in this annual report.

***Purchase of Equity Interest in Toro Corretora de Títulos e Valores Mobiliários S.A.***

On September 29, 2020, Santander Brasil's subsidiary, Santander Distribuidora de Títulos e Valores Mobiliários S.A., or "Santander DTVM," entered into an investment and other covenant agreement with the shareholders of Toro Controle e Participações S.A., or "Toro Controle," to invest in Toro Controle. Toro Controle is the holding company of Toro Corretora de Títulos e Valores Mobiliários S.A., or "Toro Corretora," and Toro Investimentos S.A., or "Toro Investimentos," which jointly run an investment platform focused on the retail market, founded in Belo Horizonte in 2010. Before the conclusion of the transaction Toro Controle was merged into Toro Corretora. We refer to Toro Controle, Toro Corretora and Toro Investimentos as "Toro."

*[**Table of Contents**](#toc)*<br>

In addition, Santander DTVM and Toro Corretora combined their market experiences to develop a comprehensive platform of fixed and variable income products. This platform is based on shared expertise and technology and operates in the growing Brazilian investment market. The completion of the transaction occurred in April 2021, following the execution of certain customary agreements between the parties, the fulfillment of customary conditions precedent and the receipt of certain regulatory approvals, including the approval of the Brazilian Central Bank.

Following this transaction, on June 7, 2023, we entered into an agreement with the shareholders of Toro Participações S.A., or "Toro Participações," for the acquisition of the remaining shares of Toro Participações. Once this transaction was completed, we became the indirect holder of all the share capital of Toro Corretora. and Toro Investimentos. After the conditions precedent established in the agreement were fulfilled, the transaction closed on January 3, 2024. Following this acquisition Toro Participações was merged into Toro Corretora on February 29, 2024. On November 4, 2025 Toro Corretora changed its name to Santander Corretora de Títulos e Valores Mobiliários S.A. following a restructuring of Toro Corretora into Santander Brazil's ecosystem of retail brokerage.

***Acquisition of Equity Interest in Apê11 Tecnologia e Negócios Imobiliários Ltda.***

On September 2, 2021, Santander Holding Imobiliária S.A., or "SHI," a wholly owned subsidiary of Santander Brasil, entered into a Share Purchase and Sale Agreement and Investment Agreement with the shareholders of Apê11 Tecnologia e Negócios Imobiliários Ltda., or "Apê11," for the acquisition of 90% of the capital stock of Apê11. Apê11 acts as a collaborative marketplace, pioneering the digitization of the purchase journey of houses and apartments.

On December 22, 2023, SHI entered into an agreement to acquire all of the outstanding shares of Apê11. As a result of this second transaction, SHI became the sole shareholder of 100% of Apê11 share capital. Following this acquisition Apê11 was merged into SHI on June 28, 2024.

***Investment in Biomas – Serviços Ambientais, Restauração e Carbono S.A.***

On November 9, 2022, our wholly owned subsidiary, Santander Corretora, entered into an investment agreement to acquire up to 20% of the share capital of Biomas – Serviços Ambientais, Restauração e Carbono S.A., or "Biomas."

***Call Option and Issuance of Notes***

In October and November 2023, Santander Brasil exercised our option to repurchase the Tier 2 debt instruments issued in 2018 in the amount of U.S.$1.25 billion. In their place to compose our Tier 2 regulatory capital, we issued financial bills (*letras financeiras*) with a subordination clause in the total amount of R$6.0 billion. These financial bills have a term of 10 years, and redemption and repurchase options in accordance with the applicable regulations.

Furthermore, on November 8, 2024, we also exercised our option to repurchase the Tier 1 debt instruments issued in 2018. In order to replace these as part of our Tier 1 regulatory capital, we issued financial bills with a subordination clause in the total amount of R$7.6 billion. These new financial bills have a repurchase clause exercisable from the date that is 10 years after their issuance date, in accordance with the applicable regulations.

***Investment in América Gestão Serviços em Energia S.A.***

On March 12, 2024, Santander Corretora entered into an agreement to acquire 70% of the share capital of América Gestão Serviços em Energia S.A. ("América Gestão").

América Gestão is an energy management company with a diversified client portfolio and a large range of service offerings such as strategic and operational energy management for consumers and plants in the free and captive markets, and sustainability projects in line with environmental and social factors. The company has more than 20 years of experience in the power sector.

***Reorganization of Return Capital***

Following this acquisition, Return Capital was merged with and into Return Gestão on September 30, 2024. As a result of this merger, Return Capital ceased to exist and its activities were taken over by Return Gestão, of which Santander Brasil is the sole shareholder. Subsequently, on November 28, 2025, a spun off portion of Return Participações was merged into Santander Brasil, as part of an initiative aimed at simplifying the group's corporate and ownership structure.

***Merger of Santander Leasing S.A. Arrendamento Mercantil into Santander Brasil***

On November 28, 2025, the merger of Santander Leasing S.A. Arrendamento Mercantil, or "Santander Leasing," into Santander Brasil was approved. The transaction aims to simplify the corporate structure of the group, unify accounting processes and reduce operating costs. The merger will only become effective upon approval by the Brazilian Central Bank. There was no increase in the share capital of Santander Brasil as a result of the transaction, since Santander Brasil already held 100% of the share capital of Santander Leasing.

**Issuance of Tier 2 Financial Bills**

On December 4, 2025 Santander Brasil carried out the private issuance and offering of subordinated financial bills in the total amount of R$2,362.8 million to private investors. The proceeds from the issuance will be used to compose our Tier 2 regulatory capital. The financial bills have a maturity of 10 years, with a repurchase option exercisable as of 2030, in accordance with the applicable regulations. The financial bills are eligible to be included in our Tier 2 capital, pursuant to Brazilian Central Bank Resolution No. 122, dated August 2, 2021.

**Capital Expenditures and Divestitures**

Our main capital expenditures include investments in our information technology platform. Our information technology platform focuses on our customers and supports our business model. In 2025, 2024 and 2023, total investments in information technology for Santander Brasil were R$2,111 million, R$1,832 million and R$2,259 million, respectively.

*[**Table of Contents**](#toc)*<br>

In 2025, 2024 and 2023, we continued to improve our technology platforms by investing in our digital applications, especially through the implementation of new solutions in the areas of artificial intelligence (e.g., machine learning, and AI for operations, or AIOPs), micro services, blockchain technology, cyber insurance, facial recognition and cloud-based technologies, among others. We believe that the application of these new technologies improved our interaction with our customers and enabled us to provide solutions across credit, consortiums ("*consórcios*"), payroll loan, insurance, private banking, cards, payments, agribusiness and investments to better address client needs. We also continued to invest in our physical distribution network (branches, PABs and PAEs), including biometric identification for corporate customers, digital purchase and payment of exchange, among other initiatives. For more details about our technology and infrastructure, see the item "—B. Business Overview—Technology and Infrastructure."

Our ongoing capital expenditure consists primarily of investments in information technology. We expect to fund our ongoing capital expenditures principally from our cash flow from operations.

For more information, see "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Principal Factors Affecting Our Financial Condition and Results of Operations."

**4B. Business Overview**

**Our Strategy**

Our strategy is centered on pursuing profitable, diversified and sustainable operations.

We are focused on becoming the most present bank in our customers' lives, striving to deliver the best-in-class experience to individuals and businesses alike. We believe that our use of technology leads improves our customers' journeys by offering relevant, tailored products to enable us to meet our customers' need when, how, and where they desire. We have strived to strengthen our customer service channels, particularly our digital platform and remote services. In addition, in our physical channels, we have a store model that positions our stores as a convenient stopover integrated within our multichannel offering.

We are guided by our strategic pillars of (i) customer centrality, (ii) scaling up, through the expansion of the customer base and a comprehensive multichannel offering, (iii) revenue diversification, striving to grow in retail deposits and commissions, (iv) expertise in credit and efficiency, seeking to strengthen our portfolio and cost management for the benefit of our customers, and (v) leveraging our key enablers, which we believe are people and technology, the key components to support our business transformation. We are aiming to build an operation capable of generating consistent and long-term results.

We also focus on maintaining sound risk management, and work to continuously improve our internal models to maintain our credit risk indicators at levels consistent with our risk management policies. In terms of costs and efficiency, we continue to develop our productivity culture, seeking to improve our operational efficiency by simplifying and digitizing processes and implementing technologies. Additionally, we are focused on maintaining discipline in capital allocation, and seek to prioritize operations with higher profitability and good asset quality.

We recorded net income of R$12,965 million, R$13,414 million, and R$9,499 million in the years ended December 31, 2025, 2024 and 2023, respectively, representing a 3.3% decrease in the year ended December 31, 2025, compared to the year ended December 31, 2024. In the years ended December 31, 2025, 2024 and 2023, we achieved capital adequacy ratios of 15.4%, 14.3%, and 14.5%, respectively. In the years ended December 31, 2025, 2024 and 2023, we reached efficiency ratios of 27.9%, 27.7%, and 29.7%, respectively. In addition, we achieved a return on average stockholders' equity of 10.6%, 11.2%, and 8.5% in 2025, 2024 and 2023, respectively, and an adjusted return on average stockholders' equity of 13.7%, 14.6%, and 11.3% in 2025, 2024 and 2023, respectively. Adjusted return on average stockholders' equity is a non-GAAP financial measure. For further information, see "Item 3. Key Information—A. Selected Financial Data—Reconciliation of Non-GAAP Measures and Ratios to Their Most Directly Comparable IFRS Financial Measures." We believe that these metrics demonstrate our track record of consistent performance and the results of our constant efforts to improve our productivity.

In recent years, we have undergone significant transformations, thereby enabling us to identify and capitalize on business opportunities. We have expanded our business to diversify our offering of products and services:

&nbsp;&nbsp;&nbsp;&nbsp;• In 2024, we remained focused on being the bank of first choice for customers in their financial decisions,
striving to provide a highly personalized offering to our 69 million customers.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ We believe this can only be done with the intensive use of technology, which we believe improves the
customer experience and reduces the cost incurred to serve our customers. We are prioritizing the primary relationship focusing on three
pillars:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Transactionality: which we define as transactions our customers do through Santander Brasil, such as
paying with credit cards or using PIX and wire transfers. We believe this is an essential part of our customer primacy strategy and a
driver of our revenue diversification efforts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Investments: the fundamental lever of our retail funding expansion plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Credit: with relentless discipline in capital allocation, being a complementary element to the other
pillars.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ In innovation and technology, we consistently worked to strengthen our culture of productivity and cost
management, always focused on providing the best experience for our customers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ We also began a new engagement approach with our customers by launching "Começa Agora"
(which means "It Starts Here") to foster closer connections with our customers. We introduced our "Santander Free"
offering which is focused on low income customers. We also sought to strengthen our tailored offering of products to our "Santander
Select" high income customers. We have also shifted our positioning in the SMEs segment, to be closer, more available and integrated
into our customers' businesses. Additionally, we have made progress in combining our Toro and other Santander Brasil offerings to
develop a market-leading investment platform combining a digital experience with human relationships with scale and technological excellence,
which we believe are key levers of our retail funding expansion plan.

&nbsp;&nbsp;&nbsp;&nbsp;• In 2025, we continued to pursue our commitment to be
the primary bank of our clients through intensive and efficient use of technology aiming to create value, hyper-personalized offers and
continuously improve customer experience. Thus, we continued to make progress with our strategic priorities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Individuals: we increased the number of customers for which we believe we
are the primary bank (which we define as customers who use at least two of the following services we provide: transaction services, loans,
and investments) by 1% in the year ended December 31, 2025 compared to the year ended December 31, 2024, which we believe is
due to our efforts to improve our offerings and customer service by combining human contact with the digital environment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Consumer Finance: we continue to provide solutions that deliver value to
our clients within a comprehensive ecosystem which we believe enables cross-selling opportunities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Companies: we continue to reinforce our commitment to being close, available,
and fully integrated into our clients' businesses, delivering tailored solutions that translate into higher productivity, profitability,
and satisfaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Payments: we are transforming the client journey and delivering a new experience.
This year, we launched PIX via credit card, combining PIX's speed with the flexibility of credit cards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Investments: we continue to evolve in our expansion plan, leveraging technology
to hyper-personalize the experience of our customers and boost productivity. In this regard, we launched Pitch Maker, an artificial intelligence
assistant that further enhances our advisors' ability to serve our customers. We also advanced in the integration of Santander Corretora
and Toro, combining the tools into a single application to simplify the customer journey with the aim of achieving gains in efficiency
and scale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ We were dedicated to continuing to have a pivotal role as a hub for innovation
and global integration within the Santander Group, working in close partnership with other regions as one Santander. The main project
launched this year was the One App, in which we put technology and global expertise at the service of customers' experience. We
believe this tool helps us understand our customers' needs by offering a solution that allows our customers to manage their entire
financial lives through this new app;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ In parallel, we keep prioritizing our portfolio diversification, and endeavor
to optimize our cost of funding by expanding our presence in the Individuals' segment; and

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ To support this process, we continue to strengthen our culture based on
empowerment, leadership, and diversity, and seek to foster an environment of innovation to leverage our digital transformation.

***Commercial Banking***

*Retail – Individuals*

Our strategy for individual customers revolves around five main pillars:

&nbsp;&nbsp;&nbsp;&nbsp;• *Cost Optimization* – Providing a more digital offering to increase the proportion of digital
interactions with our customers relative to physical interactions, which we believe improves customer experience and lowers costs.

&nbsp;&nbsp;&nbsp;&nbsp;• *Credit* – Capital optimization by shifting the portfolio mix to prioritize transactional
and higher profitability products, focusing on credit cards in particular.

&nbsp;&nbsp;&nbsp;&nbsp;• *Engagement Model* – The app as the main sales and engagement driver. Growth squads focused
on e-commerce, in addition to personalization through extensive use of open finance. In terms of human contact, we strive to leverage
every touchpoint to improve customer relationships.

&nbsp;&nbsp;&nbsp;&nbsp;• *Service Model* – The app as the primary customer channel, migrating an extensive array of
communications from the call center to the chatbot. Providing the customer with a conversational experience remotely, 90% through chats
and 10% through voice conversations, while continuing to offer brick-and-mortar branches.

&nbsp;&nbsp;&nbsp;&nbsp;• *Offering* – A simpler, digital bank focused on customer experience, featuring a free account
and card offering (our "Santander Free" offering), unlimited withdrawals, and 10 days of interest-free overdraft to strengthen
our "Santander" and "Santander Select" brands.

As of December 31, 2025, we structured the individual customer service segment as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• *Private Banking* – customers who have at least R$5.0 million in assets available for investment.
Private banking provides a comprehensive and customized range of financial products and services, including investment advisory services,
loans, and asset management, delivered by a dedicated investment and banking services manager.

&nbsp;&nbsp;&nbsp;&nbsp;• *Santander Select* – customers with a monthly income starting from R$7,000, or at least R$100,000
in investments, or customers who choose to pay for this service category, regardless of their income or amount of investments. Within
Santander Select, our goal is to understand our customers' needs at each stage of their lives and provide them with financial advisory
services through a multichannel solution in which they have the option of receiving human assistance across all channels, including financial
products and services that support their wealth accumulation and investment goals.

&nbsp;&nbsp;&nbsp;&nbsp;• *Santander Especial* – customers with a monthly income of up to R$6,999. Santander Especial
offers simple and efficient solutions with a suitable cost-benefit ratio for our customers, primarily through digital channels.

*Retail – Small and Medium-Sized Enterprises (SMEs)*

As of December 31, 2025, we served SMEs using the following customer service segmentation model:

&nbsp;&nbsp;&nbsp;&nbsp;• *Companies 3* ("Empresas 3") – responsible for companies with annual revenues
between R$30 million and R$200 million. Our service model is based on dedicated relationship managers, a team of specialists for more
complex demands, and credit managers specializing in risk management. We also provide customized services to multinational technology
companies and other large corporations to meet their specific needs.

&nbsp;&nbsp;&nbsp;&nbsp;• *Companies 2* ("Empresas 2") – responsible for companies with annual revenues
ranging from R$3 million to R$30 million. We provide these clients with a wide array of products and services, supported by dedicated
specialists in specialized hubs.

&nbsp;&nbsp;&nbsp;&nbsp;• *Companies 1* ("Empresas 1") – responsible for companies with annual revenues
of up to R$3 million. We offer these customers a streamlined banking solution through an integrated account that combines a business account
with a point-of-sale, or "POS" terminal hosted by our former subsidiary and current affiliate Getnet. Through this arrangement,
our customers receive benefits for utilizing the Getnet platform to handle their credit card sales, with their proceeds being directly
deposited into a Santander Brasil checking account.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• *Empresas Mei –* responsible for companies with an annual revenue of up to R$97,000 and registered
as an Individual Microentrepreneur *(microempreendedor individual),* or "MEI," with the Brazilian Federal Revenue Service
(*Receita Federal do Brasil*). We offer these customers a streamlined and cost-effective solution through our Santander MEI account,
a remote service and digital channels.

In January 2026, we announced a review of our SME segmentation model as follows: (1) Digital ("Empresas Digital"): businesses with annual revenues of up to R$500,000; (2) Companies 1 ("Empresas 1"): companies with annual revenues ranging from R$500,000 to R$10 million; (3) Companies 2 ("Empresas 2"): companies with annual revenues ranging from R$10 million to R$80 million; and (4) Middle Corporate, formerly Companies 3 ("Empresas 3"), which now comprises companies with annual revenues ranging from R$80 million to R$500 million.

*Consumer Finance*

We provide consumer loans for financing vehicles, goods and services, directly or through intermediary agencies, dealers and partners. Santander Financiamentos is our primary service channel, and we also operate under other brands with associated companies.

*Corporate*

Our corporate segment aims to be the main distribution channel of the Santander Group to Brazilian and foreign and/or multinational corporate customers. The product offering ranges from simple cash accounts to mergers and acquisitions advisory services. We serve companies with annual gross revenues in excess of R$80 million (as of January 1, 2026) located across Brazil through physical and digital channels. Our corporate business has been constantly evolving as a business line relying on a disciplined analytical toolkit, consistent communication, and workforce upskilling.

***Global Wholesale Banking***

Santander Corporate & Investment Banking, or SCIB, is the global business unit that serves customers who, due to their size and complexity, require tailored services or high-value-added wholesale products. In this segment, we provide a wide range of domestic and international financial services to large Brazilian and multinational companies. Our customer portfolio comprises a range of industries, including telecommunications, retail, aviation, real estate and logistics, power, construction and infrastructure, natural resources, food, agribusiness, and financial institutions. Our customers in the SCIB segment benefit from the Santander Group's global structure of services, which is supported by its worldwide-integrated wholesale banking network and global services solutions, as well as local market expertise and integrated services.

**Our Portfolio of Products and Services**

***Payments and Loyalty***

*Cards*

We operate in the credit and debit card market, catering to both account holders and non-account holders. Most of our customers are individuals to whom we offer a range of cards to address each customer profile.

In 2025, we focused on our business expansion through integrated initiatives that combined data, technology, and customer centricity.

We sought to improve our pricing with Smart Pricing, using AI, machine learning, and elasticity testing to price our credit products better. Another example is *PIX no Cartão,* which allows customers to make payments and transfers via PIX using their credit card limit, with options for payment in full or in up to 12 installments, including payment in up to three future billing cycles. This initiative unified traditional credit with instant payments.

*[**Table of Contents**](#toc)*<br>

Furthermore, to attract new customers and boost the frequency of service usage, we rolled out promotions with offerings, such as the *Bateu Ganhou* campaign, which set monthly spending goals for customers and rewarded them with points or cash back, and the *Temporada de Férias* campaign, which was designed to strengthen relationships with high-income clients by offering convenience and exclusive benefits such as loyalty points and exemptions from the payment of certain fees.

In the SMEs segment, we offer an integrated solution in a digital journey for businesses, with a unified offering of account, credit card, and merchant acquiring services within a single ecosystem. We believe this integrated approach simplifies financial management and improves cash flow.

We also launched a new, redesigned and unified app that integrates account and card services into a single experience, while also allowing users to view information regarding accounts they have at other banks. We believe that this solution strengthens our relationship with our customers and offers a more fluid, modern, and intuitive journey.

The following table shows key financial and operational metrics of our credit card business as of the dates and for the periods indicated.

ending December 31, 2025 was not available as of the date of this annual report.

*Santander Way*

Santander Way is an app designed for our cardholders, allowing them to manage their Santander Brasil cards effortlessly, at any time and from anywhere. This comprehensive card management tool features numerous functionalities, such as the ability to make payments, add cards to digital wallets, and participate in promotional campaigns, among others.

*Esfera*

We continue to offer our loyalty program, Esfera, which we believe creates avenues to expand into new markets and leveraging cross-selling within our ecosystem.

***Payroll Loans***

We provide payroll loans to both account holders and non-account holders. Loan repayments are automatically deducted from customers' monthly salaries by their employers and then transferred to Santander Brasil, significantly lowering our credit risk in comparison to other types of loans. Payroll loans are accessible to our customers through our digital platforms and physical branches. Our customers can refinance their payroll loans, as well as choose from other options to help them manage their debts.

***Real Estate Loans***

We offer long-term financing to our customers for the purchase of real estate, with the property itself serving as collateral for the loan. For this reason, a real estate loan is a strategic product due to its lower risk and potential for increasing customer loyalty.

We provide real estate financing that adheres to regulatory standards for prime loans for this type of lending. This means: (i) capping the financing at a maximum of 80% of the property's purchase price; (ii) requiring customers to have a minimum monthly income, verified by recent pay stubs and tax documents that confirm their employment status or other income sources, enabling us to assess their creditworthiness; and (iii) ensuring that any additional debt combined with the financing does not surpass 35% of the customer's gross monthly income.

To streamline the property financing process for our customers, we have created an innovative digital platform, including digital signatures and electronic registration, ensuring a digital journey and structured data transmission directly to the property registry office.

The following table sets forth certain key financial and operating data regarding our real estate business as of the dates indicated:

(1) Ratio between loans and the value of the collateral, excluding home equity.

***Home Equity***

We offer a home equity financing solution named "UseCasa" for individuals and "UseImóvel" for businesses, where customers can secure a loan by using their property as collateral. We are the market leaders among private-sector banks in Brazil for this type of financing, holding a portfolio market share of 20% as of December 31, 2025, according to ABECIP.

***Microfinance***

The mission of "Prospera Santander Microfinanças," our microfinance program, is to foster financial inclusion by providing access to credit and financial guidance to low-income micro and small entrepreneurs. The microcredit offer is made by our local specialists, through a fully digitized process, empowering microfinance loan recipients to expand their businesses. In addition to microcredit, we offer access to checking accounts and other banking services, products and financial education. We hope to positively impact the social and economic development of the local communities in which we operate.

***Consortiums* (*"Consórcios"*)**

Consortiums operate on a collaborative financing model, where a group of individuals and/or companies come together to purchase a specific asset in an egalitarian and self-funded manner. Contributions are pooled into a common fund, which is dedicated to acquiring the asset agreed upon at the start. Throughout the duration of the agreement, members of the consortium group receive the asset through lotteries and competitive bidding. Typically, consortium groups are formed for the purchase of durable goods, such as real estate and vehicles.

We provide a consortium offering for our customers aligned with the prevailing interest rate and credit conditions in the market. In 2025, we broadened the distribution of the product through our "Perto Patrimonial," a channel dedicated to sale of consortiums. Seeking better customer satisfaction, we have sought to strengthen the post-sales journey and to improve our offering with new features.

***Agribusiness***

Agribusiness remains a relevant sector for Santander Brasil, despite the turmoil the sector has faced in recent years. After nearly a decade of expansion, the sector entered a period of structural deterioration that began during the pandemic, when rising production costs—driven by disruptions in supply chains—coincided with exceptionally high margins and abundant credit availability. This environment led many producers to significantly increase their leverage. Starting with the 2022/2023 harvest, climate events in the South and Northeast regions of Brazil reduced national production, while competing countries such as Argentina logged record harvests. This imbalance expanded global supply and pressured commodity prices, pushing margins down to historic lows. Further climate events occurred during the 2023/2024 harvests, which led to further pressure on margins. At the same time, the increase in the SELIC rate to contain inflation raised the cost of credit and made the debt levels assumed by some producers during periods of high margins unsustainable.

Although the crisis is significant, its impacts are not uniform. Many producers maintained adequate leverage levels and continue to operate normally within the sector's historical margin parameters. The 2025/2026 harvest, for example, is already almost entirely planted, with no productive areas being abandoned.

We are working closely with customers, offering renegotiation solutions and guiding the necessary deleveraging process, whether through narrowing operational scope or selling assets. To strengthen risk governance, we have expanded our credit recovery teams and created a dedicated portfolio to monitor the most stressed clients. We expect a full normalization of the sector will take a few years. During this period, more robust and selective credit models—less dependent on traditional guarantees—are likely to emerge, changes that should structurally strengthen the market and reduce vulnerabilities like those seen in the recent cycle.

*[**Table of Contents**](#toc)*<br>

The following table sets forth certain key financial and operating data regarding our agribusiness portfolio as of the dates indicated.

***emDia***

*emDia* is a 24/7 omnichannel collection company offering its customers both call center and digital solutions. We have been investing in the use of technology, focusing on hyper-personalization and a multichannel journey.

***Return Capital***

Return Capital specializes in managing and securitizing nonperforming assets. We actively seek cross-selling opportunities within our ecosystem, leveraging the flow of customers and the extensive reach of our business.

***Insurance Ecosystem***

We offer our insurance products through Santander Corretora de Seguros, helpS, Auto Compara, and Santander Auto S.A., or "Santander Auto." Our insurance business as a whole generated R$17.1 billion in premiums in the year ended December 31, 2025.

*Santander Corretora de Seguros* 

Santander Corretora de Seguros provides a diverse range of products designed to meet the needs of every customer profile. We offer a comprehensive portfolio of insurance and protection services, delivering all-encompassing solutions. Our portfolio includes life and personal accident insurance, vehicle and property coverage, credit insurance, as well as insurance for travel and banking transactions, among other products.

According to the SUSEP report from October 2025, we have a market share of 8.2% across the lines of business which we operate.

We are continually refining our insurance solutions to address the evolving needs of our customers, striving to deliver an enhanced experience from the first purchase to the policy renewal.

*helpS* 

helpS is our assistance and convenience services business, providing 24/7 emergency solutions for homes, cars, motorcycles and pets. It also provides access to a 24/7 telemedicine platform, a network of discounts on consultations, exams, and pharmacies, bodywork and painting repairs, and streaming services. The benefits are linked to the individual**'**s taxpayer ID, rather than to a specific asset, thus allowing customers to request assistance whenever, wherever, and for however they want. Through "Santander+ Combos," the customer can create a basket of services of their choice for a fixed monthly fee, which is designed to be lower than the cost of these same services when purchased separately.

*Automotive Insurance Ecosystem*

The Brazilian insurance market is characterized by: (i) a low level of insurance penetration relative to its GDP; (ii) outdated technology and dominated by companies with low innovation rates that prioritize financial results (due to a history of high interest rates); and (iii) a distribution network predominantly composed of retail brokers. Consequently, only approximately 30% of Brazilian vehicles were insured as of September 2025, according to CNSeg (*Confederação Nacional das Seguradoras)*. In this context, we provide the following automotive insurance solutions:

&nbsp;&nbsp;&nbsp;&nbsp;• *Santander Auto:* Santander Auto provides a fully digital vehicle insurance solution that
 uses data analytics to set prices and features a one-click purchase process, seamlessly integrated with vehicle financing options.
 Leveraging actuarial techniques and behavioral modeling, Santander
Auto offers insurance quotes without requesting additional information from customers. This is possible with data that is already available
to us. Our objective is to grow the business by capitalizing on our ecosystem and engaging a larger portion of our customer base. We believe
this approach has been key to the development of Santander Auto. In March 2025, we launched a new insurance product called *Mão na Roda*. It combines coverage for minor repairs, wheel and suspension services, and small damages caused by theft or robbery, for
cars and motorcycles. We are also planning to offer Santander Auto's products through new channels.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• *Auto Compara*: Auto Compara is a leading digital comparison platform that offers car and motorcycle
insurance alternatives. We offer an end-to-end digital journey so that customers can purchase their car insurance in a simple, fast and
secure way. In addition, we are the car insurance solution for our retail bank and are available to millions of customers through our
mobile app or through our commercial team. As of December 31, 2025, we featured products from 11 different insurers (which accounted for
nine out of the 10 largest in the Brazilian market, according to SUSEP).

***Consumer Finance***

*+Negócios \| Santander Financiamentos*

Our "+Negócios" platform enables credit simulations, processes credit approvals, and formalizes vehicle financing proposals, while also providing portfolio management reports. The platform has evolved and is now also used to cross-sell insurance products, as well as new offerings, such as car equity loans.

Additionally, we offer the "+Fidelidade" program, a loyalty-building initiative aimed at providing incentives to banking correspondents based on their engagement with the entire Santander Brasil ecosystem. We centralize the business strategy in the program by implementing a loyalty journey for dealers and sellers.

We also have a structure to support our customers after sales, through several tools, such as our customer portal and WhatsApp.

*Webmotors*

Webmotors is a Brazilian technology company that operates an online marketplace specializing in car buying and selling solutions for dealerships, original equipment manufacturers, or "OEMs," and private sellers. Moreover, it is the largest automotive ecosystem platform in Brazil, according to IPSOS Branding Tracking 2023.

On April 28, 2023, Santander Corretora de Seguros, Investimentos e Serviços S.A. completed the sale of a 40% equity stake in Webmotors S.A. to CAR Group Limited, an Australian multinational company. As a result, Santander Corretora now holds a 30% stake in Webmotors, while CAR Group Limited owns the remaining 70%. This strategic partnership combines the market-leading position of Santander Brasil in automotive financing in Brazil with the expertise of CAR Group Limited, a global leader in the automotive marketplace.

For more information, see "Item 4. Information on the Company—A. History and Development of the Company—Important Events—Sale of a portion of Santander Corretora's shareholding in Webmotors."

***Cash Management***

We offer a broad suite of online cash management solutions for corporate customers and SMEs through our internet banking and mobile banking platforms. Our cash management revenue streams include fees derived from the following services:

&nbsp;&nbsp;&nbsp;&nbsp;• Collections – assisting customers in executing commercial transactions through printed or electronic
payment slips.

&nbsp;&nbsp;&nbsp;&nbsp;• Payments – enabling efficient and automated processing of accounts payable, whether through individual
transactions or batch file submissions.

&nbsp;&nbsp;&nbsp;&nbsp;• Instant payments – allowing customers to make and receive payments with immediate debiting or
crediting of accounts. This capability can be integrated with our collections, payments, or product-acquisition products.

&nbsp;&nbsp;&nbsp;&nbsp;• Payroll services – streamlining the distribution of wages and benefits to employees via an online
platform.

&nbsp;&nbsp;&nbsp;&nbsp;• Custody services – providing management and safekeeping of predated checks until their clearing
dates.

In addition, we offer customized cash-management and treasury solutions designed to meet the specific operational needs of our customers, supporting efficiency, liquidity management, and day-to-day business operations.

***"Advance Program" (Programa Avançar)***

In addition to our financial services offering, we also have the "Advance Program" (Programa Avançar), a free, non-financial platform designed to support entrepreneurs — whether they are Santander Brasil customers or not. Launched in 2015, the program gives SMEs access to a comprehensive set of business-development resources, including educational content, certified courses, and events focused on management, innovation, internationalization, and team development. We believe the Advance Program is a strategic differentiator within our SME value proposition and an important tool for fostering entrepreneurship in Brazil.

***Customer Funding***

Our main sources of liquidity are customer funding through deposits and other bank funding instruments. These deposits, combined with equity and other instruments, enable us to meet most of our liquidity and legal reserve requirements.

For further information, please refer to "Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Liquidity and Funding."

***Investments*** – ***Funding Plan Progress***

Our investment ecosystem is designed to provide a comprehensive advisory experience that supports customers in achieving their financial objectives. The model is structured around five fundamental pillars:

&nbsp;&nbsp;&nbsp;&nbsp;• *Customer investment profile* – We assess each customer's circumstances in order to
determine their level of financial knowledge, investment horizon, liquidity needs and risk tolerance. Customer profiles are reviewed periodically
to ensure continued alignment with their objectives and with applicable regulatory requirements.

&nbsp;&nbsp;&nbsp;&nbsp;• *Investment strategy* – Our investment philosophy focuses on generating long-term returns
through a disciplined asset allocation process supported by a robust model that incorporates historical asset behavior and advanced financial
simulations. Diversification across asset classes is an essential element for mitigating portfolio risks.

&nbsp;&nbsp;&nbsp;&nbsp;• *Recommendations* – We prepare model portfolios on a monthly basis to guide product recommendations
for each customer profile. These portfolios are the result of a rigorous process led by our asset allocation committee, which considers
economic projections, product scoring systems and ongoing market monitoring. Products with stronger evaluations are included in the recommended
portfolio, while those with lower performance are reviewed for potential reallocation. This process incorporates analysis from our Advisory,
Economics, Santander Asset Management, Private Banking and Santander Corretora teams.

&nbsp;&nbsp;&nbsp;&nbsp;• *Execution and implementation* – We offer a broad range of financial instruments, including
banking products, fixed income securities, equities, structured notes, multimarket funds, real estate funds, exchange-traded funds (ETFs)
and other capital markets solutions. We follow an open architecture approach that includes third-party funds selected through a rigorous curation process, as
well as diversified fixed income alternatives and structured products distributed by Santander Corretora. Our partnership with Zurich
Santander further expands this offering with a comprehensive portfolio of private pension plans.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• *Monitoring* – We conduct ongoing reviews of each customer's profile, objectives and
performance to ensure their investments remain aligned with current recommendations and market conditions.

***AAA***

Launched in June 2022, AAA offers a comprehensive range of products, complemented by a sophisticated digital experience and expert guidance to further strengthen our investment advisory services. AAA provides an exclusive investment advisory service for high-net-worth individuals. To incentivize our AAA investment advisors, their remuneration includes a substantial variable component that is contingent on the results they generate for our customers. As of December 31, 2025, AAA had 1,754 investment advisors and was present in 180 cities across Brazil.

***Toro***

In 2025, Santander Brasil integrated Toro Investimentos into its ecosystem and initiated a new phase of its investment strategy, which includes the consolidation of the retail brokerage operation under the Santander Corretora brand. This phase also includes the expansion of our product offering, including the distribution of cryptoassets, which we believe supports our strategy to expand available options, modernize the customer experience and enhance our competitiveness in an increasingly dynamic market. This initiative is part of our strategic plan to simplify the client journey, strengthen market positioning and accelerate innovation.

**Customer Service Channels**

We offer our financial services and products to customers through a multichannel distribution network, which includes: (i) physical channels, such as branches, mini branches, and ATMs; (ii) remote channels, such as call centers; (iii) external channels, consisting of banking correspondents and third-party vendors of our products and services; and (iv) digital channels, including online banking and mobile banking platforms.

The following table provides an overview of the weight of each key distribution channel in our overall distribution system.

|:---|:---|:---|:---|
|  | **For the Year Ended December 31,** | **For the Year Ended December 31,** | **For the Year Ended December 31,** |

| Remote Channel (3) | 0.7 | 1.4 | 1.8 |

---

(1) Includes Internet and mobile banking.

(2) Includes ATMs and branches.

(3) Includes interactive voice response, call centers and chatbot.

***Digital Channels***

In 2025, we focused on attracting qualified customers and increasing the profitability and loyalty of our customer base. We achieved an NPS of 69 for our digital channels as of December 31, 2025.

Our number of digital customers, which we define as individuals who have utilized at least one of Santander Brasil's digital channels, such as mobile or internet banking, within the 30 days prior to the end of the applicable year, reached 25 million, an increase of 6.2% in the year ended December 31, 2025 compared to the same period in 2024. Additionally, 98.5% of all of the transactions processed by Santander Brasil in 2025 were digital, that is, transactions conducted through internet banking, mobile banking, and other digital platforms. We believe that these numbers demonstrate the importance of digital channels in enhancing customer experience and fostering sustainable business growth. In addition, we believe these numbers are evidence of the increased adoption of digital channels by customers and the efficiency of the digital model in addressing their needs.

*[**Table of Contents**](#toc)*<br>

***Remote Channel***

Our remote channel consists of voice customer services and sales, interactive voice response, or "IVR," and a chatbot with the option for human interaction in the chat.

In 2025, we continued to focus on providing a unique experience for our customers by offering personalized services. We recorded 49.8 million interactions during the year, with 42% of interactions happening through chat.

In line with this purpose, we focus on assisting vulnerable customers (i.e., individuals who, due to their personal conditions (whether temporary or permanent), demonstrate a reduced ability to understand and assess information for decision-making or to represent their own interests) through the IVR fast pass, enabling them to receive prompt service. This has enabled us to provide a more human interaction to these vulnerable customers.

***External Channel***

Our external channel consists of sales representatives and banking correspondents who distribute our products and services alongside our other channels. The channel focuses on the origination of four main products: payroll loans, consortiums ("*consórcios*"), real estate loans, insurance, customer prospecting and integrated accounts.

***Physical Network***

Our distribution network provides integrated financial services and products to our customers. The table below presents our physical distribution network, all located within Brazil, as of the dates indicated.

*Mini branches ("PABs")*

We provide everyday banking services to our SME customers, as well as to corporate customers and their employees, through our mini branches ("PABs"). These exclusive service locations are strategically placed within our customers' buildings, including hospitals and universities. The presence of PABs at our customers' facilities bolsters our relationships and fosters loyalty, as they benefit from the convenience of conducting banking transactions on-site at their workplaces.

*[**Table of Contents**](#toc)*<br>

*Automated teller machines ("ATMs")*

As of December 31, 2025, we operated a network of 6,006 ATMs, including those located in our branches and mini branches. Furthermore, our clients have access to the "Banco24Horas" network, which, as of December 31, 2025, consisted of 26,705 self-service terminals. Through this network, our customers can access their accounts, conduct banking transactions, and purchase most of the products and services available in our portfolio.

**Technology and Infrastructure**

In 2025, we reinforced the central role of technology in enabling our strategy of being a digital bank with branches with a strong presence in our customers' lives, further accelerating the digitalization of our businesses and optimizing the integrated operation of our physical, digital and remote channels.

In a context of increasing account creation per person and rising competitiveness among the digital solutions offered by the main players in the Brazilian financial market, we intensified the use of technology to deeply understand customers' real needs and offer hyper-personalized products and services, as well as solutions that enable customers to manage their financial lives, including across several banks, without losing our focus on the continuous improvement of customer service and experience across all journeys.

F1RST Digital Services, our technology company, maintained its key strategic role in enabling and supporting the businesses, with a culture driven by innovation and the development of technology talent to deliver secure and stable technological solutions with agility. F1RST Digital Services works in a partnership model with our various business areas and with a mindset focused on making customers' lives easier, going beyond delivering products and services to strive for excellence in customer experience. We also highlight notable advances across the main pillars of the technology operating model:

&nbsp;&nbsp;&nbsp;&nbsp;• *Technology Teams Merged with the Business*: Our functional structures for delivering technology
solutions, the Business and Enterprise Domains, were reviewed and aligned to the global operating model, with the local implementation
of the Global Domains, our functional structures for delivering products and services for the businesses, in alignment with the global
operating model, seeking to expand collaboration with global teams in the design, development and implementation of components for the
global platforms. We believe this change enhances our ability to develop scalable solutions that bring greater value to the business and
to customers at the global, regional and local levels.

&nbsp;&nbsp;&nbsp;&nbsp;• *Innovation and Technical Excellence*: We strengthened our innovation culture by creating a Chief
Data Analytics and AI Office structure aligned with our global strategy, dedicated to accelerating the cross-functional application of
AI solutions across businesses and internal processes, with the objective of expanding the potential gains in productivity and efficiency.
In addition, we increased the sharing of code and engineering and architecture best practices between local and global teams, enhancing
the technical quality of our technology solutions.

&nbsp;&nbsp;&nbsp;&nbsp;• *Operations Stability and Resilience*: Our "Always On" culture, which centers on ensuring
the highest level of stability and resilience in our operations, remained central. We strengthened the active and cross-functional participation
of technical specialist teams in resilience engineering to monitor, educate, and enable tools that help solution-delivery teams enhance
the stability of their systems. Additionally, we restructured the governance area, placing greater emphasis on the periodic monitoring
and reporting of key operational indicators, and we established new stability forums, with the participation of our Chief Information
Officer and technical leadership, to ensure continuous follow-up on the definitive remediation of incidents' root causes.

&nbsp;&nbsp;&nbsp;&nbsp;• *Talent Attraction and Training*: In line with our strategy of attracting and developing technology
talent, we invested in training so that our employees can build a solid foundation in technology topics and thereby enhance the value
delivered to the business. We expanded the training offerings in our cloud enablement program in partnership with Amazon Web Services
(AWS Level Up Program), including new tracks for certification in "AI" and "Machine Learning Engineering", and
today our internal training platform (Tech Knowledge) includes more than 110 learning journeys and training programs for various technology
career paths.

We believe these advancements enable technology to support the growth of the business, delivering high-quality services and experiences to our customers. Below we list other technology highlights from 2025:

&nbsp;&nbsp;&nbsp;&nbsp;• *Investments*: In pursuit of becoming a leading investment platform in the market, grounded
 in human-scale relationships and digital excellence, we invested in technology to deliver a hyper-personalized experience to our customers and increase the productivity of our advisors.
We launched Pitch Maker, an AI assistant that correlates and analyzes data in real time to understand the investor profile and generate
portfolio and product recommendations within seconds, enabling faster, smarter, and more tailored service for each customer. This empowers
our advisors to deliver high-quality, personalized service, as evidenced by the high customer satisfaction levels, with an NPS of 87 points
as of December 31, 2025 (an increase of six points since December 31, 2024).

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• *Individual Bank Account (Digital Channels)*: In line with our ambition to be the customer's
primary bank, we improved our digital experience with the launch of our new mobile application (One App), an innovative and comprehensive
multi-bank solution that seamlessly connects our customers to our entire ecosystem, allowing them to manage their financial lives simply
and fully. The application was built on a global platform with a modern architecture, delivering greater efficiency and standardization
in the development of scalable components, while ensuring increased resilience and security. Moreover, the new application was developed
based on continuous customer feedback, with more than 90 surveys conducted and over 100,000 customers consulted, with the goal of offering
an experience that goes beyond the traditional banking relationship, focusing on value creation through intuitive and personalized journeys.
We highlight three main advantages of the new home screen (Global Position), which serves as the customer's gateway to the new digital
experience:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ A consolidated view of all the customer's financial information such as balances, limits, cards,
and investments supporting faster and more informed decisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Dedicated conversational spaces designed to enable more personal conversations between the bank and
customers through financial-management content and personalized offers that are always aligned with the customer's products and
life stage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Simplified customer service through quick access to the main support channels, such as the chatbot,
specialists, and the help center.

&nbsp;&nbsp;&nbsp;&nbsp;• *Corporate Bank Account (Digital Channels)*: We refined the experience we offer, making it simpler,
more efficient and better aligned with what we believe are the real needs of businesses. We introduced new open finance and payments features
in the channel, enabling the centralization of customers' financial resources at Santander Brasil and ensuring greater automation and
efficiency for recurring payments. We also enhanced the transactional experience with improvements to the checking account statement and
by increasing the number of simultaneous DDA (Authorized Direct Debit – "Débito Direto Autorizado" in Portuguese)
payments from 10 to up to 150, ensuring greater agility for high-volume operations. On the security front, we provided a new "Security
Center," increasing customers' ability to monitor and control access and devices, ensuring greater protection in the digital
environment. These initiatives reinforce our commitment to offering secure and productivity-oriented digital solutions that simplify companies'
financial management, customer primacy and satisfaction, in a context of increasing digital channel usage.

&nbsp;&nbsp;&nbsp;&nbsp;• *Cards*: We advanced in the development of our new global card platform, built on a cloud infrastructure
and a modern architecture that enables simplified creation and integration of new offers and products, in addition to customer-centric
limit management. More than 20 million debit cards have already been migrated to the new processing platform, delivering immediate benefits
such as the automation of the card dispute workflow. In addition, we introduced Pix via credit cards, a new payment method that combines
the speed of Pix transactions with the flexibility of credit cards. This new option allows customers to make Pix payments via mobile using
their credit card limit and to split the amount into up to 12 installments, offering greater financial flexibility—especially in
situations where there is no available account balance or when customers prefer to allocate their balance to other priorities.

&nbsp;&nbsp;&nbsp;&nbsp;• *Payments*: We modernized our payments architecture, enabling all Pix processing on the new global
payments platform of the Santander Group (Payments Hub), and facilitated the payment experience by introducing a unified field that recognizes
all types of payments, allowing customers to make all their payments in one place. Additionally, we implemented new payment solutions,
including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ PIX payments using the customer's credit card limit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Contactless PIX, enabling customers to make payments even faster and more securely using Google Wallet
by simply tapping their smartphones on NFC-enabled terminals, eliminating the need to open the banking app or scan QR codes.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Automatic PIX, which enables simple and instant recurring payments, replacing the traditional direct
debit system that depends on business days and banking hours.

We also enhanced payment security by offering customers "AutoMed", a mobile feature for disputing Pix transactions resulting from scams or fraud, and by strengthening our internal security and resilience capabilities for Pix and payment application programming interfaces.

&nbsp;&nbsp;&nbsp;&nbsp;• *Security:* We invested in technology to strengthen security layers across our products and financial
transactions. For example, we created "Security Alert," an additional protection layer in the mobile app that combines artificial
intelligence with financial-behavior analysis to identify risk situations in real time during financial transactions such as Pix transfers
or "*boletos*" (Brazilian bank payment slips) payments to suspicious contacts. The alert is triggered whenever the system
detects unusual transaction behavior, and the app displays a notification prompting the customer to review and confirm whether they want
to proceed with the transaction.

&nbsp;&nbsp;&nbsp;&nbsp;• *Generative Artificial Intelligence, or GenAI:* We continued to expand the adoption of GenAI across
the organization to deliver a better customer experience, supported by a newly established Data Analytics and AI structure dedicated to
ensuring alignment with the global strategy and the responsible use of this technology, in accordance with the frameworks and policies
set within the Santander Group. We highlight the following domains in which we expanded GenAI adoption:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Sales and Investment Advisory*: Improved quality and agility in personalized product and investment
recommendations, contributing to higher offer-conversion rates and increased customer satisfaction and retention, while also improving
the productivity of sales teams.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Customer Service*: AI models were enhanced to improve chatbot and virtual-assistant capabilities,
enabling faster and more accurate responses, resulting in higher customer satisfaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *CRM Models*: Categorization of credit card and checking account transactions using data collected
through Open Banking, enabling a deeper understanding of customers' financial lives, both within and outside Santander Brasil, and
supporting more tailored product offerings that better meet customer needs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Security*: Improvements in capabilities for detecting and preventing fraudulent activities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Technology Operational Efficiency:* Expanded adoption of tools that support our developers throughout
the software development lifecycle, ensuring greater quality and efficiency in planning, design, coding, testing, and systems maintenance.
In addition, the adoption of our system obsolescence reduction solution was broadened.

&nbsp;&nbsp;&nbsp;&nbsp;• *Hyper-Personalization:* We continued to invest in our customer interaction platform, which enables
the capture of insights and the development of a 360º view of the customer's profile and behavior based on their interactions
with us, optimizing the intelligent and personalized offering of products and services. We believe this has allowed us to improve our
ability to anticipate customers' needs, enhance their digital experience and strengthen their relationship with us. As a result
of this behavior-based product offer strategy, we have sought to increased customer engagement with contextualized campaigns as well as
the digital conversion of offered products.

&nbsp;&nbsp;&nbsp;&nbsp;• *Open Finance:* We enhanced our open finance platform with the implementation of solutions that
help customers easily manage their financial lives through a complete multi-bank experience, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ We introduced the new "Bring Money" feature in the mobile app, allowing customers to easily
and securely transfer money or salary from their accounts at other banks to Santander Brasil, without leaving the app or undergoing repeated
authentication steps. The app connects to the selected bank to complete the validation and displays the transfer confirmation on the screen.
The app can also notify customers to bring money from another account whenever their Santander balance is low near a bill's due
date, helping them better manage financial commitments. Since its launch in June 2025, more than 100,000 customers have adopted the service,
which we believe has also generated value for companies by enabling more efficient payment and cash-flow management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ We expanded the strategic use of customer-authorized data from other institutions to improve the accuracy
of our risk models and further tailor our product and service offerings, in addition to digital navigation improvements, such as simplifying
how balances from other bank accounts are displayed on the home screen.

*[**Table of Contents**](#toc)*<br>

We believe that these developments, among others, further refined customer experience and will help us strengthen our position as our customers' primary bank.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Operational Resilience:* Providing high-quality and stable products and services remained a strategic
priority for our technology group. In addition to our ongoing focus on refining our secure-development, telemetry and automation capabilities,
we established new recurring executive forums with the participation of senior technology group leaders to conduct an in-depth review
of the major incidents that affected our operations, with an emphasis on identifying vulnerabilities and permanently resolving issues—for
example, contingency strategies involving alternative providers to maintain the availability of critical services for customers. Additionally,
we continued investing in the development of resilience-engineering specialists, who work cross-functionally, supporting all software
development teams with expertise and tools to ensure end-to-end availability of systems and platforms for customers. We believe that these
practices help strengthen our operational resilience over the medium and long term and contribute to delivering a differentiated customer
experience.

***Communications and Marketing***

In 2025, our Global Brand Guide was launched, establishing a new visual identity and unified communication guidelines. All marketing and communication initiatives were conducted with a clear focus on customer benefits, aiming to enhance brand relevance and reinforce its strategic positioning.

Several institutional and commercial campaigns were implemented throughout the year. At the beginning of the year, the "Começos" (which means "beginnings" in Portuguese) campaign was launched to open the year and reinforce the global brand tagline. Subsequently, an investment-focused campaign was rolled out under Santander Select, targeting the high-net-worth and affluent client segment.

In the second half of the year, the positioning of Santander Empresas, under the theme "The bank that left the bank to enter your business" highlighted Santander Brasil's value proposition for the corporate and SME segments, emphasizing its strengths in relationship management, proximity to clients, and specialized service capabilities.

In addition, several other relevant initiatives were undertaken during 2025, including:

&nbsp;&nbsp;&nbsp;&nbsp;• The continued development of the Smusic platform, offering exclusive discounts and benefits for clients
at international concerts, as well as sponsorship of the Todo Mundo no Rio event featuring a performance by Lady Gaga. We believe these
initiatives contributed to increased brand awareness and high levels of engagement across digital and social media channels. We believe
the Smusic campaign has boosted Santander Brasil's engagement on social media.

&nbsp;&nbsp;&nbsp;&nbsp;• Global sponsorship of Formula 1, providing exclusive experiences for Santander Brasil clients during
the São Paulo Grand Prix, alongside tailored commercial offerings during the period, including vehicle financing solutions.

In terms of internal communications, we continued with our monthly live event "Together with Mario Leão," broadcast to our employees through the "Santander Now" app. In 2025, we created a newsletter called "Acontece Santander" (which means "It happens at Santander" in Portuguese) covering culture, people, sponsorships, innovation and sustainability. We achieved an average email opening rate of 47% across the 10 issues we published. We also worked on non-financial asset campaigns, generating engagement and pride in belonging. At Santander Now, our main content platform for the internal audience, we had more than 600 thousand unique users accessing content in the year. In addition, we had the launch of the NOW Assistant, using GenAI, to streamline and support mainly the service of the commercial network, with content for day-to-day action. We also launched Open NOW, a forum for sharing ideas and improvements (of processes and experience), to bring inputs to strengthen the organization's reputation for our products and services. We also launched the Single Communication Guide, a document with guidelines and good communication practices to help employees have a clear, simple, and objective conversation with customers (internal and external) in all service channels. Finally, we worked on the review of chatbot journeys with the objective of standardizing and disseminating the tone of voice, through participation in squads and review of journeys with customers in the channels (chatbot, voice, human chat, apps, internet banking and Whatsapp).

***Sustainability Initiatives***

Our sustainability history started over 20 years ago. Throughout this period, we have refined our programs, businesses and governance relating to sustainability.

The key focus throughout this time has been on the assessment and mitigation of social, environmental, and climate risks when providing loans, assistance to businesses that support customers' transition toward a low-carbon economy, and the building of a more inclusive society through actions in education, employability and entrepreneurship. To ensure proper governance of this process, we rely on internal policies and controls supported by our senior leadership.

Our sustainability efforts are carried out under our Social, Environmental and Climate Responsibility Policy ("PRSAC", in Portuguese), which outlines social, environmental, and climate principles and directives for conducting business and engaging with the organization's stakeholders. The PRSAC aims to prevent negative impacts and to maximize positive impacts arising from our financial operations and activities. The PRSAC meets the requirements of CMN Resolution No. 4,945/2021 and SUSEP Resolution No. 666/2022.

We expanded our internal training course offerings on sustainability topics to some of our affiliates. We monitor specific sustainability goals, which are used to evaluate the performance of executives and other employees and directly impact their variable compensation.

In 2021, we announced our ambition to achieve net zero emissions in our operations, credit portfolios, and investments by 2050, through the use of internal methodologies that take input and recommendations from the Net Zero Banking Alliance, or "NZBA" guidelines. We expect that customer engagement and support, through transition financing, will be the main paths to achieving our reduction targets.

We have engaged with the Brazilian federal government's initiatives to steer the transition to a low-carbon economy, not only through advocacy efforts but also through active and direct participation. One example is the "Eco Invest Program," structured by the Brazilian National Treasury and aimed at attracting foreign capital to finance projects supporting climate transition through blended financing mechanisms. In 2025, one Eco Invest auction took place - focused on the restoration of degraded pastures - and two new auctions have been announced, aimed at exchange rate mechanisms to attract private equity investments and projects in the bioeconomy, respectively. Santander has been actively contributing to the dialogue with the National Treasury and has been granted one of the largest allocations in the two auctions that have already taken place, with a total commitment to mobilizing R$7.15 billion to eligible projects.

In relation to the establishment of our decarbonization plans for the most carbon intensive sectors, we have focused our efforts on the agriculture sector given the significance of agricultural production in Brazil. To start this journey, in 2022 we sought the specialized support of WayCarbon, a Brazilian company renowned for solutions aimed at decarbonizing the economy. Since then, we have been working together on the development of methodologies and metrics with scientific references, which enable us to estimate the sector's emissions and understand the production links with decarbonization potential. In 2025, we participated in a study by the FGV to develop decarbonization curves for soy, corn, and beef cattle.

We also participate in the Banking for Impact on Climate in Agriculture (B4ICA) initiative, coordinated by the World Business Council for Sustainable Development in partnership with the United Nations Environment Programme Finance Initiative (UNEP FI), the Partnership for Carbon Accounting Financials (PCAF), and the Environmental Defense Fund (EDF), along with other banks, contributing to the development of guidelines that assist the sector in transitioning to a low-carbon economy, continuously improving the measurement and accounting of emissions associated with agribusiness.

As part of our climate ambition, we manage the environmental impact of our own operations by measuring and disclosing scope 1, 2 and relevant scope 3 emissions from our buildings, offices and branches, prioritizing reduction over compensation. Over the past decade, our efficiency initiatives have significantly reduced scope 1 and 2 emissions, supported by multi-year plans that combine more efficient facilities, better maintenance and operations, technology upgrades, and the purchase and self-production of renewable energy. We continue to offset the residual scope 1 and 2 emissions we are unable to eliminate through carbon credits selected based on a rigorous due diligence process. With respect to scope 3, our focus is on emissions from our portfolio, that is, financed emissions; at the Santander Group level, we have decarbonization targets for the most carbon-intensive sectors.

Regarding sustainability frameworks, we continue to follow the guidelines of the Global Reporting Initiative (GRI), the Task Force on Climate-Related Financial Disclosures (TCFD), Sustainability Accounting Standards Board (SASB) and of the principles of integrated reporting. We also connect our activities to the UN Sustainable Development Goals. Since 2023, we began considering the impact of the IFRS S1 and S2 standards, launched by the International Sustainability Standards Board (ISSB), which became mandatory for a large range of companies in Brazil as of January 1, 2026, in accordance with CMN Resolution No. 5,185/2024 and CVM Resolution No. 193/2023.

*[**Table of Contents**](#toc)*<br>

Our main achievements in 2025 include the following:

&nbsp;&nbsp;&nbsp;&nbsp;• We enabled R$38.6 billion in sustainable businesses (including both balance sheet financing and issuances
of indebtedness or other financing which we have facilitated) including green bond issuances, clean energy financing, and dedicated product
options.

&nbsp;&nbsp;&nbsp;&nbsp;• We maintained market leadership in decarbonization credits (*créditos de descarbonização)*,
or CBIOs, with a 41% share of the CBIOs in Brazil in the year ended December 31, 2025 according to data from the B3.

&nbsp;&nbsp;&nbsp;&nbsp;• With the aim of supporting our customers in the transition towards a low-carbon economy, we hosted a
series of events called "Climate Dialogues" as preparation for the COP30. In partnership with WayCarbon, we discussed topics
such as transportation and mobility, decarbonization of basic industries and agribusiness. We also participated in more than 50 strategic
forums held in Brazil and abroad on the subject, reinforcing our commitment to the global climate agenda. Among the events we participated
in, we can highlight the Brazil Climate Investment Week, the London Climate Week, Febraban Tech, and the World Economic Forum.

&nbsp;&nbsp;&nbsp;&nbsp;• In 2025, we facilitated the first transaction of the New Climate Fund focused on reforestation in Brazil,
with an investment of R$100 million, of which R$80 million came from the climate fund and R$20 million from a BNDES financing line.
The transaction was guaranteed by Santander Brasil, which we believe marks a significant advance in the mobilization of private capital
for climate solutions. The beneficiary was Mombak, a startup specializing in carbon removal, which works on the restoration of degraded
areas in the Amazon. This Mombak project will be implemented in the state of Pará and aims at the recovery of Amazonian biodiversity,
large-scale carbon removal, and the generation of local jobs, promoting a new economy of the standing forest.

&nbsp;&nbsp;&nbsp;&nbsp;• Biomas, an ecological restoration company co-founded by Santander Brasil and five other companies, launched
its first forest restoration project in partnership with Veracel Celulose in the south of the state of Bahia. The Muçununga Project
aims to recover 1,200 hectares of the Atlantic Forest, planting two million seedlings of over 70 native species, such as yellow ipê,
jatobá, and jacaranda-da-bahia. With an initial investment of R$55 million, we believe the project has the potential to generate
500,000 carbon credits over 40 years, with a premium market value due to the high integrity of the credits and the positive impacts on
biodiversity and local communities. We believe that this initiative also promotes environmental benefits, such as improved soil and water
quality, and social benefits, such as job and income generation in municipalities in the region.

&nbsp;&nbsp;&nbsp;&nbsp;• We launched the "Ability without Limits" program, a journey for hiring and training professionals
with disabilities.

&nbsp;&nbsp;&nbsp;&nbsp;• In microfinance, Prospera achieved a credit production of R$5.2 billion in the year ended December
31, 2025, a 6% increase over the year ended December 31, 2024. The total portfolio grew 5% compared to December 31, 2024, reaching R$3.5
billion as of December 31, 2025, with a total active customer base of 1.2 million as of December 31, 2025. Beyond the financial results,
Prospera impacted more than 10,000 people with Educar para Prosperar, our in-person financial education program for clients and non-clients
in the communities where we operate.

&nbsp;&nbsp;&nbsp;&nbsp;• In educational initiatives carried out by Santander Brasil, more than 11,000 people have benefited through
programs in Brazil. The awarding of 80 scholarships to university students at the University of Salamanca to learn Spanish and the offering
of 15,000 Artificial Intelligence scholarships for teachers are some of the initiatives undertaken. In 2025, the innovation and technology
committee was created and added to the structure of the advisory committees to the board of directors to foster and oversee the implementation
of innovation initiatives throughout our organization.

&nbsp;&nbsp;&nbsp;&nbsp;• The pillars of our volunteering program are financial education, professional development and safeguarding
the rights of children, teenagers and the elderly. We have provided financial education to teenagers and adults and mentoring for young
people, as well as organized a winter clothing campaign, among other volunteering initiatives.

In 2025, we monitored the execution of 65 projects from the *Amigo de Valor* program and 47 projects from the *Parceiro do Idoso* program. More than 8,000 children, elderly people, and their families were directly benefited by the assistance we provided. When taking into account the total amount mobilized by Santander Brasil, its affiliates, clients and employees, the reach of the initiatives exceeds 20,000 people.

*[**Table of Contents**](#toc)*<br>

We also launched a new campaign to support projects that will be executed throughout 2026. Over R$26 million were raised to support 59 projects of the *Amigo de Valor* program aimed at expanding and improving the provision of social assistance services for children and adolescents in vulnerable situations. R$18.5 million were raised to support 47 projects of the *Parceiro do Idoso* program that will contribute to promoting dignified aging and improving local public policies.

&nbsp;&nbsp;&nbsp;&nbsp;• We launched the Santander Integrated Social Program with the goal of expanding social impact in municipalities
with greater social vulnerability and a strong bank presence. The initiative combines different areas of action, focusing on local development,
income generation, and improving the quality of life for the population. The first phase took place in 30 municipalities in the states
of Pernambuco and Maranhão, all with low human development index scores, and focused on cultural and sporting activities.

&nbsp;&nbsp;&nbsp;&nbsp;• Through the provision of tools based on our financial education policy, such as communication processes
in the customer journey and product journey, lectures, and courses, more than 48 thousand people were impacted by some form of financial
education action. Our financial education portal presents content, guides, and spreadsheets to support financial health. We also engage
in community-oriented volunteer activities and various lectures.

&nbsp;&nbsp;&nbsp;&nbsp;• We also have a diverse and independent board of directors, with 45% of members being women and 45% of
members being independent as of December 31, 2025.

In recognition of our environmental, social and governance efforts, we have been awarded "Best Bank for Sustainable Finance in Brazil 2025" by Euromoney magazine and we also received the "LatinFinance Project & Infrastructure Finance Awards" in three different categories in 2025: Infrastructure Bank of the Year in Latin America; Renewable Energy Finance of the Year; and Road Finance of the Year.

During COP30, we participated in the "B3 ESG Index Triad Celebration," which brought together 30 companies that stand out for their good ESG practices and performance. The award-winning companies are part of the three main sustainability indices of B3: ISE (Corporate Sustainability Index), ICO2 (Efficient Carbon Index), and iDIVERSA (Diversity Index). We also achieved an A-rating from CDP, the largest database on corporate practices related to climate change, emissions, water, and forests.

**Competition and Industry Transformation**

Currently, there are five commercial financial institutions at the forefront of the Brazilian financial services industry in terms of assets: Santander Brasil, Bradesco, Itaú Unibanco, Banco do Brasil and Caixa Econômica Federal. Together, these financial institutions accounted for 66.9% of the credit and 66.1% of the deposits available in Brazil as of September 30, 2025, according to the Brazilian Central Bank and the interim financial statements of the aforementioned banks.

The following table shows the total loans and deposits of the five leading financial institutions in Brazil as of September 30, 2025:

**Insurance Coverage**

We maintain insurance policies that are renewed annually in order to protect our assets. Substantially all of our branches, affiliates and administrative buildings are insured against losses caused by fire, lightning, explosions and other risks. Such coverage provides for the reimbursement of the costs of asset replacement.

*[**Table of Contents**](#toc)*<br>

In addition, we also maintain the following insurance policies:

&nbsp;&nbsp;&nbsp;&nbsp;• policies against material and/or bodily damage caused to third parties for which we are held responsible;

&nbsp;&nbsp;&nbsp;&nbsp;• policies against financial losses due to fraud or employee misconduct, among others;

&nbsp;&nbsp;&nbsp;&nbsp;• directors' and officers' insurance policy for our management against third-party complaints
regarding management acts. There are also insurance policies against crimes, employee dishonesty and damages arising out of public offerings;
and

&nbsp;&nbsp;&nbsp;&nbsp;• policies against hacker attacks and cybercrimes.

**Dependence on Patents, Licenses, Contracts and Processes**

The major trademarks we use, including, among others, the "Santander" trademark, are owned by Santander Investment Bank. Santander Brasil has a license to use this trademark. All trademarks of our business are registered or applied through the Brazilian Patent and Trademark Office (*Instituto Nacional de Propriedade Industrial*, or "INPI"), the agency responsible for registering trademarks, patents and designs in Brazil. After registration, the owner has exclusive rights to use of the trademark in Brazil for a 10-year period that can be successively renewed for equal periods.

As of the date of this annual report, we own or have a license to use a total of 454 trademarks in Brazil, with Santander Brasil owning over 87 of these trademarks, while the remaining are owned by other companies of the Santander Group.

**REGULATION AND SUPERVISION**

The basic institutional framework of the Brazilian financial system was established by Law No 4,595/64, as amended from time to time, or the "Banking Reform Law." The Banking Reform Law created the CMN, responsible for establishing the general guidelines of monetary, foreign currency and credit policies, as well as regulating the institutions of the financial system.

**Principal Regulatory Agencies**

***CMN***

The CMN oversees the Brazilian monetary, credit, budgetary, fiscal, and public debt policies. The board of the CMN is composed of the president of the Brazilian Central Bank, the Minister of Planning, and the Minister of Finance, who also chairs the Board. Pursuant to the Banking Reform Law, the CMN is the highest regulatory entity within the Brazilian financial system, and is authorized to regulate the credit operations of Brazilian financial institutions, to regulate the Brazilian currency, to supervise Brazil's gold reserves and foreign exchange, to determine Brazilian savings and investment policies and to regulate the Brazilian capital markets with the purpose of promoting the economic and social development of Brazil. In this regard, the CMN also oversees the activities of the Brazilian Central Bank and the CVM.

***Brazilian Central Bank***

The Brazilian Central Bank is an autonomous authority responsible for the implementation of CMN policies related to foreign currency and credit, the regulation of Brazilian financial institutions, particularly in regard to the minimum capital and compulsory deposit requirements, as well as the disclosure of the transactions carried out by financial institutions and their financial information. The Brazilian Central Bank addresses specific issues through the COPOM, a committee responsible for adopting measures to meet inflation targets defined by the CMN and establishing monetary policy guidelines. In order to meet inflation targets, the COPOM must set the target for the SELIC rate (the average rate for daily financing, backed by federal instruments, as assessed under the SELIC) and publish reports on the Brazilian economic and financial environment and projections for the inflation rate.

***CVM***

The CVM is responsible for the implementation of CMN policies related to securities, with the purpose of regulating, developing, controlling and inspecting the securities market and its participants (companies with securities traded in the market, investment funds, investors, financial agents, such as custodians of instruments and securities, asset managers, independent auditors, consultants, as well as instruments and securities analysts).

*[**Table of Contents**](#toc)*<br>

***Self-Regulating Entities***

The Brazilian financial and capital markets are also subject to the regulation of self-regulating entities that are divided by field of activity. These self-regulating entities include, among others, the ANBIMA, the ABECS, the FEBRABAN, the Brazilian Association of Publicly-Held Companies (*Associação Brasileira das Companhias Abertas – ABRASCA*) and the B3.

**Principal Limitations and Obligations of Financial Institutions**

In line with leading international standards of regulation, Brazilian financial institutions are subject to a series of limitations and obligations. In general, such limitations and obligations concern the offering of credit, the concentration of risk, investments, operating procedures, loans and other transactions in foreign currency, and the administration of third-party funds and microcredit. The restrictions and requirements for banking activities, established by applicable legislation and regulations, include the following:

&nbsp;&nbsp;&nbsp;&nbsp;• No financial institution may operate in Brazil without the prior approval of the Brazilian Central Bank.
In December 2017, the CMN enacted a new rule establishing that all such requests submitted to the Brazilian Central Bank must be approved
within 12 months (subject to suspension of the term in some instances);

&nbsp;&nbsp;&nbsp;&nbsp;• A Brazilian financial institution may not hold direct or indirect equity interests in any company located
in Brazil or abroad registered as permanent assets without prior approval of the Brazilian Central Bank. The corporate purpose of such
company shall be complementary or subsidiary to the activities carried out by the financial institution;

&nbsp;&nbsp;&nbsp;&nbsp;• Brazilian financial institutions must submit for prior approval by the Brazilian Central Bank the corporate
documents that govern their organization and operation, such as capital increases, transfer of headquarters, opening, transfer or closing
of branches (whether in Brazil or abroad), election of the members of the statutory bodies and any corporate restructuring or alteration
in the composition of their equity control. The requests for changes in control submitted to the Brazilian Central Bank must be approved
within 12 months and requests for changes to organizational documents must be approved within three months (in both cases subject to suspension
of the term in some instances);

&nbsp;&nbsp;&nbsp;&nbsp;• Brazilian financial institutions must fulfill minimum capital and compulsory deposit requirements and
must comply with certain operational limits;

&nbsp;&nbsp;&nbsp;&nbsp;• A Brazilian financial institution may not own real estate, except for properties it occupies and subject
to certain limitations imposed by the CMN. If a financial institution receives real estate, for example, in satisfaction of a debt, such
property must be sold within one year, unless otherwise authorized by the Brazilian Central Bank;

&nbsp;&nbsp;&nbsp;&nbsp;• Brazilian financial institutions must comply with the principles of selectivity, guarantee, liquidity
and risk diversification;

&nbsp;&nbsp;&nbsp;&nbsp;• A Brazilian financial institution belonging to the segment one, or "S1" (i.e., banks with
an asset base equivalent to over 10% of Brazil's GDP or that engage in relevant international activity), as is our case, cannot
lend more than 25% of its Tier 1 regulatory capital (*patrimônio de referência*) to a single person or a group and the
maximum exposure to concentrated individual customers or group of connected customers of such Segment 1 financial institution is 600%
of its Tier 1 regulatory capital (a concentrated individual client would mean, for the purpose of the proposed rule, any one client to
which exposure is equal to or higher than 10% of its Tier 1 regulatory capital);

&nbsp;&nbsp;&nbsp;&nbsp;• According to the Banking Reform Law, a Brazilian financial institution cannot carry out credit transactions
with (i) its controlling shareholders, directors and members of other statutory bodies (fiscal, advisory and other) and their respective
spouses and relatives up to second degree, (ii) the individuals or legal entities that hold a qualified interest (15% of the capital stock)
in their capital, (iii) the legal entities in which they have qualified interest (direct or indirect), (iv) the legal entities in which
they have effective operational control or preponderance in the deliberations, regardless of the equity interest, and (v) the legal entities
with common directors or members of the board of directors. Such prohibition does not apply, subject to limits and conditions established
by the CMN through the enactment of Resolution No. 4,693 in October 2018, to (i) transactions with a counterparty that has an officer
or director in common with the financial institution providing credit, provided that the officer or director is considered an independent
member in both entities, (ii) transactions carried out under market-compatible conditions, without additional benefits or different benefits
when compared to the operations deferred to the institution to other customers with the same profile, (iii) credit operations that have
as counterparty a financial institution that is part of the institution prudential conglomerate, provided that they contain contractual
clauses of subordination, except in the case of overnight and loan
transactions with other financial institutions specified by the law, (iv) the interbank deposits, according to the law, (v) the obligations
assumed by related parties under the compensation and settlement services authorized by the Brazilian Central Bank or by the CVM and their
respective counterparties and (vi) other cases authorized by the CMN;

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• The management of third-party assets must be segregated from other activities and must follow the regulations
issued by the CVM;

&nbsp;&nbsp;&nbsp;&nbsp;• The total amount of funds applied in permanent assets of the financial institutions cannot exceed 50%
of their adjusted stockholders' equity;

&nbsp;&nbsp;&nbsp;&nbsp;• Brazilian financial institutions must comply with anti-money laundering, combating the financing of
terrorism and anticorruption regulations;

&nbsp;&nbsp;&nbsp;&nbsp;• Brazilian financial institutions must implement policies and internal procedures to control their systems
of financial, operating and management of information, as well as their conformity to all applicable regulations;

&nbsp;&nbsp;&nbsp;&nbsp;• Brazilian financial institutions must implement a policy for remuneration of board members and executive
officers that is compatible with their risk management policies; and

&nbsp;&nbsp;&nbsp;&nbsp;• The Banking Reform Law and specific regulations enacted by the CMN impose penalties on financial institutions
in certain situations where applicable requirements, controls and requisites have not been observed. In addition, the Brazilian Central
Bank may cancel the financial institution's authorization to operate in certain situations. The cancellation of an authorization
for operation of a financial institution may only occur upon the establishment and processing of the appropriate administrative proceeding
by the Brazilian Central Bank.

Additionally, as part of the Santander Group and due to the global nature of our organization, we are subject to related international rules.

**Capital Adequacy and Leverage – Basel**

***Current Requirements***

The Brazilian Central Bank supervises the Brazilian banking system in accordance with the Basel Committee on Banking Supervision, or "Basel Committee," guidelines and other applicable regulations. For this purpose, banks provide the Brazilian Central Bank with any information that it deems useful in performing its supervisory functions, which includes supervising changes in solvency and capital adequacy of banks.

The main principle that guides the directives set forth in the Basel Committee is that a bank's own resources must cover its principal risks, including credit risk, market risk and operational risk.

Brazilian financial institutions are subject to capital measurement and standards based on a risk weighted asset ratio. The parameters of this methodology resemble the international framework for minimum capital measurements adopted by Basel III.

***Basel III***

In 2010, the Basel Committee issued its Basel III framework, which was revised and republished in 2011. The Basel III framework increases minimum capital requirements, creates new conservation and countercyclical buffers, changes risk-based capital measures, and introduces a new leverage limit and new liquidity standards in comparison to the former framework. The rules were phased in gradually and were fully implemented by January 1, 2019. Regulatory capital is composed of core capital and two additional tiers:

Tier I capital will have to reach a minimum ratio of 6.0% (according to the schedule established by the Brazilian Central Bank), divided into two portions: (i) core capital consisting mainly of corporate capital and profit reserves (shares, units of ownership, reserves and earned income) of at least 4.5%, and (ii) Additional Tier I capital consisting mainly of perpetual hybrid securities and capital instruments authorized by the Brazilian Central Bank (but excluding amounts relating to funding instruments issued by other local or foreign financial institutions) and any of our own shares purchased by us and the integration of which into the Additional Tier I Capital is permitted. To improve the quality of the capital of financial institutions, Basel III restricts the acceptance of financial instruments that fail to demonstrate effective capability of absorbing losses and requires the reduction of assets that in certain situations could jeopardize the financial institution's capital value due to the instruments' low liquidity, dependence on future profits for realization or difficulty of value measurement.

*[**Table of Contents**](#toc)*<br>

There is also an additional 2% of Tier II capital requirement, for a total of 8% of minimum capital ratio. Current hybrid subordinated debts approved by the Brazilian Central Bank as additional capital requirements, or Tier II, are expected to be maintained if they also comply with requirements introduced by Basel III, including the mandatory conversion clauses into equity or write-off upon the occurrence of triggering events provided for in the regulations.

In accordance with the Basel III standards, the Brazilian Central Bank created the additional core capital buffer (adicional de capital principal), which is composed of the sum of three buffers:

&nbsp;&nbsp;&nbsp;&nbsp;• Core Capital Conservation buffer (Adicional de Capital Principal de Conservação), which
was introduced to ensure that banks have an additional layer of usable capital that can be drawn down when losses are incurred. Whenever
the buffer falls below 2.5%, automatic constraints on capital distribution (for example, dividends, share buybacks and discretionary bonus
payments) will be imposed so that the buffer can be replenished.

&nbsp;&nbsp;&nbsp;&nbsp;• Countercyclical capital buffer (Adicional Contracíclico de Capital Principal), which aims to
protect the banking sector from periods of excess aggregate credit growth that have often been associated with the buildup of system-wide
risks. The countercyclical capital buffer is fixed by the Financial Stability Committee (Comitê de Estabilidade Financeira) based
on discussions about the pace of credit expansion, and currently is set zero (Brazilian Central Bank Communication No. 44,254/25). Should
the requirement increase, the new percentage takes effect twelve months after the announcement.

&nbsp;&nbsp;&nbsp;&nbsp;• Core Capital Systemic buffer (Adicional de Importância Sistêmica de Capital Principal),
which is applicable to the S1 bank segment (banks with an asset base equivalent to over 10% of Brazil's GDP or that engage in relevant
international activity).

On March 16, 2020, due to the challenging macroeconomic environment resulting from the COVID-19 pandemic, the CMN issued Resolution No. 4,783 which established a phase-in percentage to be applied to the risk-weighted assets value for the purpose of calculating the capital conservation buffer. This percentage increased gradually until April 2022, when it reached 2.5%. Resolution No. 4,783 was subsequently replaced by Resolution No. 4,958 of October 21, 2021, which maintained the risk weighted asset percentage for the purpose of calculating the capital conservation buffer at 2.5%.

The chart below shows the evolution of our core capital:

![](image_008.jpg)

Financial Institutions in Brazil are subject to the capital rules set by CMN Resolutions No. 4,955/2021 and No. 4,958/2021. The Basel III rules also provide for the implementation of a leverage ratio calculated by dividing the Tier I capital by the bank's total exposure. In early 2015, the Brazilian Central Bank issued a new regulation governing the calculation and reporting of the leverage ratio of Brazilian financial institutions in line with the Basel III rules, which became effective in October 2015. S1 financial institutions, as is our case, or segment 2, or "S2," for purposes of the application of prudential rules, are required to maintain a minimum Leverage Ratio (Razão de Alavancagem, or "RA") of 3% as from January 1, 2018.

*[**Table of Contents**](#toc)*<br>

In 2015, the CMN and the Brazilian Central Bank also issued a set of rules for the implementation of the liquidity coverage ratio or "LCR," a short-term liquidity index. The purpose of the LCR is to demonstrate that financial institutions have sufficient liquid assets to make it through a stress scenario lasting one month.

According to these rules, the largest Brazilian banks were required to maintain an LCR of at least 60% since October 2015. This ratio increased 10% annually until it reached 100% in 2019.

As mentioned above, the LCR is a short-term liquidity ratio for a 30-day stress scenario. It represents the ratio of high-quality liquidity assets to net outflows within the period. High Quality Liquidity Assets are composed mainly of Brazilian federal government bonds and reserve requirements. Net Outflows are mainly composed of losses on deposits, offset in part by Inflows, which are mainly credits.

In November 2017, the CMN also established a minimum limit for the Net Stable Funding Ratio (Índice de Liquidez de Longo Prazo, or "NSFR") and the RA with which Brazilian financial institutions are required to comply. The NSFR corresponds to the ratio between the Available Stable Funds (Recursos Estáveis Disponíveis, or "ASF") and the Required Stable Funds (Recursos Estáveis Requeridos, or "RSF") of the financial institution. The current regulatory minimum is 100%.

***Regulation Concerning Credit, Market, and Operational Risk***

On March 16, 2022, the Brazilian Central Bank introduced Resolution No. 229, which took effect in July 2023. Aligned with the Basel III framework, this new directive enforces the minimum standard set by the Basel Committee on Banking Supervision (BCBS) for computing the capital requirement associated with credit risk under the standardized approach (RWA<sub>CPAD</sub>). This regulation supersedes Brazilian Central Bank Circular No. 3,644, issued on March 4, 2013, in line with the stipulations of the Basel III framework.

The directive introduces a finer granularity to the weights applied to exposures, introducing refinements in the differentiation of credit risk within the prudential framework. It specifically targets financial institutions categorized in Segments 1 (S1), such as us, to Segment 4 (S4) that presently adhere to the standardized approach for credit risk assessment.

***Recent Developments in Prudential Regulation***

On April 26, 2023, the Brazilian Central Bank issued Resolution No. 313, which came into effect in July 2024 and addresses the second phase of the Brazilian Central Bank's market risk framework (FRTB). This resolution establishes the procedures for the daily calculation, using a standardized approach, of the portion of RWA related to the calculation of the capital required for exposures to the credit risk of financial instruments classified in the trading book (RWADRC). The changes provided by the resolution include the separation of the calculation of capital requirement for exposures subject to credit risk in the trading book from those classified in the banking book. This separation enables the elimination of exposure protected by credit derivatives and encourages institutions to incorporate hedging mechanisms into their portfolios to reduce effective exposure to risk.

With respect to operational risk, the Brazilian Central Bank issued Resolution No. 356, on November 28, 2023, which came into effect in January 2025 and will be implemented gradually until 2028, softening its impact on the capital requirements of supervised entities. This resolution replaces the three calculation methodologies for RWAOPAD currently in use (BIA, ASA and ASA2) with a single, more robust and risk-sensitive method, including an internal loss component that modulates the capital required.

On December 23, 2024, the CMN and the Brazilian Central Bank issued Resolution No. 5,199 to establish a transition schedule to incorporate the impacts on regulatory capital due to the new provisioning model set forth under those rules and based on IFRS 9. This transition schedule aligns with the Basel Committee recommendations, which allow jurisdictions to phase in the effects on regulatory capital resulting from increased provisions following the adoption of IFRS 9. The approved regulation partially restores regulatory capital that may have been reduced due to the shift to the new provisioning model. Details of the implementation will be communicated in due course, and the rules came into force on January 1, 2025.

On May 30, 2025, Resolution No. 5,221 was issued, which amends CMN Resolutions No. 4,950 and No. 4,911, regarding the preparation and reporting of accounting documentation by the prudential conglomerate. The rule establishes that, as of July 2026, financial institutions may calculate the leverage ratio on a standalone basis, referred to as the prudential sub-conglomerate (subconglomerado prudencial). The prudential sub-conglomerate is composed of the lead institution of the conglomerate and other entities incorporated in Brazil that are part of the prudential conglomerate, provided there are no restrictions on the transfer of assets among the institutions.

*[**Table of Contents**](#toc)*<br>

Based on the introduction of the standalone basis calculation structure, the CMN issued Resolution CMN No. 5,222 on May 14, 2025, enhancing the framework for risk and capital management and the calculation of the liquidity coverage ratio (Liquidez de Curto Prazo), or LCR. As from September 2025, financial institutions are required to implement policies, strategies and procedures to ensure the timely transfer of liquidity among the entities of the prudential conglomerate in the event of liquidity or capital shortfalls. Additionally, the rule establishes that the LCR must be calculated on a standalone basis, based on the prudential structure adopted by the institution.

On May 14, 2025, the CMN also issued Resolution No. 5,223, which updated minimum leverage ratio requirements for financial institutions. The rules introduced an individualized leverage ratio requirement, in addition to the existing consolidated requirement. The regulation also implements a phased compliance schedule, with the requirements taking effect in full by 2028, and sets differentiated minimum ratios for individual and consolidated bases. These changes aim to align Brazil's prudential standards with international Basel III recommendations and address concerns regarding the need for individual-level prudential oversight within financial conglomerates.

Moreover, in November 2025, the Brazilian Central Bank released Public Consultation No. 128, proposing amendments to RWACPAD regulations to refine recognition of credit risk mitigation instruments (financial collateral, bilateral netting, personal guarantees, credit derivatives, and credit insurance) and to revise the CEM for derivatives by aligning key parameters with SA-CCR (including a 1.4 multiplier and PFE floor). By means of the proposed new rules, the Brazilian Central Bank intends to allow single netting sets across derivatives and securities financing transactions. The draft rule also introduces preferential risk weights for specified payroll-deducted retail exposures and clarifies eligibility and haircuts for recognized collateral. The public consultation will be open for comments until February 3, 2026.

**Other Applicable Laws and Regulations**

***Consolidated Enterprise Level (Conglomerado Prudencial)***

Financial institutions must submit to the Brazilian Central Bank, monthly and semiannually, consolidated financial statements based on the "consolidated enterprise level" (*conglomerado prudencial*) of which the financial institution is a member. Such information serves as the basis for calculation of the required regulatory capital of the Brazilian institutions. The "consolidated enterprise level" includes data relative to the financial institutions and other institutions authorized to operate by the Brazilian Central Bank, consortium administrators, payment institutions and credit factoring companies, including real estate credit, or of credit rights, such as mercantile foment companies, securitization companies and specific purpose companies, located in Brazil or abroad, as well as other legal entities headquartered in Brazil that have equity participation in the mentioned entities as their exclusive business purpose.

On January 29, 2020, the CMN published Resolution No. 4,818, which requires S1, S2 or segment three, or "S3" financial institutions to publish IFRS financial statements. The requirement is already in force for publicly held financial institutions and financial institutions which are leaders of a prudential conglomerate and came into effect for all remaining financial institutions on January 1, 2022.

***Compensation Rules for the Management of Brazilian Regulated Institutions***

In September and November 2024, the Brazilian Central Bank and the CMN introduced new regulations addressing the compensation policies for officers of financial institutions, payment institutions, and other entities under its authorization. These measures, outlined in CMN Resolution No. 5,177 and BCB Resolution No. 432, which came into force on January 1, 2025, replaced the previous CMN Resolution No. 3,921, in effect since 2010. The new framework introduces enhancements aimed at aligning the current regulation with international standards for governance, risk management, and transparency, while expanding the applicability of these rules to smaller institutions.

A cornerstone of the new framework is the obligation for institutions to establish compensation policies that ensure variable compensation aligned with long-term performance and effective risk management. Among the key provisions, at least 50% of variable compensation must be paid in shares or equivalent instruments, and at least 40% of the total compensation must be deferred for a minimum period of three years. These deferred payments will be subject to malus mechanisms, which allows for reductions or cancellations in cases of financial losses or other adverse outcomes. Moreover, extraordinary payments to executives upon their departure are restricted unless they align with the institution's risk and value creation frameworks.

*[**Table of Contents**](#toc)*<br>

Governance requirements under the new regulations are also enhanced. Larger institutions, particularly those listed as public companies or leaders within designated financial segments, are required to establish statutory compensation committees, which must include independent members and have the task to oversee the design and implementation of compensation policies. For smaller institutions, the responsibility for such functions may be assigned to the company's board of directors.

The regulations also impose heightened transparency requirements. Institutions are now required to disclose annual reports detailing their compensation practices, which must include comprehensive descriptions of the performance metrics used, the mechanisms for risk adjustment, and the allocation of various compensation components.

By updating these rules, the CMN and Brazilian Central Bank seek to strengthen the governance and sustainability of regulated institutions, ensuring that compensation practices support prudent management and long-term stability across the sector.

***Recent Developments on Banking as a Service (BaaS)***

On November 28, 2025, the Brazilian Central Bank and the CMN issued Joint Resolution No. 16, which regulates the provision of Banking as a Service, or BaaS, by financial institutions, payment institutions, and other entities authorized to operate by the Brazilian Central Bank. Joint Resolution 16/25 defines BaaS as the contractual arrangement under which BaaS providers make specified financial and payment services available to clients through an integrating entity that interfaces with clients, and it clarifies the definitions of the BaaS service, the BaaS provider institution, the BaaS service-taking entity, and the client, while expressly excluding activities such as correspondent banking services, data processing/cloud services, Open Finance partnerships, and activities of sub-acquirers and network service providers from the BaaS scope.

Joint Resolution 16/25 sets forth that BaaS contracts may cover, exclusively, one or more of the following services: (i) opening, maintenance and closing of demand deposit, savings deposit, and prepaid or postpaid payment accounts; (ii) payment services conducted through those accounts; (iii) merchant acquiring services; (iv) credit operations (offer, contracting, administration, and collection); and (v) additional services that may be included by the Brazilian Central Bank in the future. It requires that services be provided by authorized institutions within their permitted activities and via electronic channels through system/platform/process integrations between the BaaS provider and the service-taking entity. It also sets conditions on account ownership, payment transaction flows, and debtor identity for credit operations, and clarifies that services outside the listed scope are not BaaS and cannot be offered as such.

BaaS contracts must specify the object, roles and responsibilities, remuneration, security measures, Brazilian Central Bank access rights to information, client demand handling, restrictions on fees charged in the name of the service-taking entity, declarations regarding the prohibition on unauthorized financial activities, and restrictions on sub-contracting BaaS services, among other terms. They must also ensure transparency about the status of the service-taking entity (including that it is not an institution authorized by the Brazilian Central Bank, as applicable), responsibilities for client communications (including upon termination and for credit portability and post-cession rights), data sharing necessary to fulfill responsibilities, and the provision of information for KYC, fraud prevention, and AML/CFT procedures. The contracts must address resolution scenarios and termination, including access by the resolution authority, advance notice of service interruption, transparency to clients, and client options regarding relationships with the provider and the service-taking entity.

The provider institution bears responsibility for the reliability, integrity, availability, security, confidentiality, and regulatory compliance of services provided under BaaS, including KYC, fraud prevention, and AML/CFT. While ancillary tasks may be performed by the service-taking entity, the provider must supply the necessary tools and remains responsible, and SCR access/sharing with the service-taking entity is prohibited for ancillary tasks related to credit operations. Institutions acting as BaaS providers or service-taking entities must designate a director responsible for compliance with the resolution.

***Naming Regulations for Authorized Institutions in Brazil***

On November 28, 2025, the Brazilian Central Bank and the CMN issued Joint Resolution No. 17, which governs the nomenclature and public presentation of institutions authorized to operate by the Brazilian Central Bank. The rule applies to the institution's full nomenclature – comprising its corporate name, trade name, brand, and internet domain – and to any medium used for communication or public presentation to clients and users.

*[**Table of Contents**](#toc)*<br>

Joint Resolution 17/25 requires institutions to include, in their corporate names, terms that clearly reference the scope of their authorization to operate granted by the Brazilian Central Bank. It prohibits use, in any nomenclature, of terms — whether literally or by morphological or phonetic similarity — that suggest activities or an institutional type for which the entity does not have specific authorization. Cooperatives may reference their cooperative system in their nomenclature. Institutions that are part of a prudential conglomerate may incorporate the conglomerate's name, provided it is clear to clients which type of institution within the conglomerate they are interacting with and the conglomerate's name does not include terms identifying a type of institution not included in the conglomerate.

***Private Payroll Deduction Loans***

Law No. 10,820, of December 17, 2003, as amended by Law No. 15,179, of July 24, 2025, modernizes the framework for private payroll-deduction loans by facilitating the use of digital platforms for both the solicitation and management of these credit arrangements.

The reform is intended to enhance efficiency, strengthen security, and improve accessibility for workers. Under the updated rules, formal employees — including rural workers, domestic workers, and registered sole-proprietor micro-entrepreneurs (MEIs) — may apply for loans on more favorable terms directly through Brazil's official Digital Work Card application. Loan repayments are capped at 35% of the borrower's gross salary, with the option to pledge up to 10% of the FGTS (Severance Indemnity Fund) balance or up to 100% of the termination indemnity payable upon dismissal without cause as collateral, and installments are deducted automatically from payroll via the national eSocial system.

The measure is expected to deliver tangible benefits to workers by expanding access to lower-interest credit facilities and reducing administrative costs. For the first 120 days following the launch of the systems or platform, funds from new payroll-deducted loan transactions with authorized institutions must be used exclusively to repay either (i) non-payroll-deducted loans with outstanding installments without collateral, or (ii) payroll-deducted loans with outstanding installments, provided the borrower has such active obligations on the date the new loan is granted.

These new credit operations may be offered by any duly authorized payroll-deducting institution and must carry an interest rate lower than that of the original loan being refinanced. In such cases, lending institutions are required to report the relevant loan data to the designated public operating agents. This priority repayment structure is intended to encourage the replacement of higher-cost debt with cheaper, payroll-deducted alternatives, thereby contributing to broader economic stimulus.

***New Accounting Criteria Applicable to Financial Instruments, Hedging, Leasing Agreements and Accounting Standards***

On November 25, 2021 and December 16, 2021, the CMN issued Resolution No. 4,966/2021 and Resolution No. 4,975/2021. These rules establish, respectively, new accounting principles and criteria applicable to financial instruments, as well as to hedging and financial leasing transactions contracted by financial institutions and other institutions authorized to operate by the Brazilian Central Bank.

The rules intend to align the accounting criteria applicable to financial instruments and leasing agreements contracted by financial institutions and other entities supervised by the Brazilian Central Bank with best international practices, including the "IFRS 9 – Financial Instruments" and "IFRS 16 – Leases" standards issued by the IASB.

CMN Resolution No. 4,966/2021 and Resolution No. 4,975/2021 came into effect on January 1, 2025, ensuring a transition period for the institutions subject to the changes.

Furthermore, on March 28, 2023, the Brazilian Central Bank issued Resolution No. 309 (superseded by Resolution No. 352 of November 23, 2023 which has substantially the same purpose of Resolution No. 309 and includes consortium administrators, payment institutions, securities brokers, foreign exchange brokers and securities distribution companies in its scope). Resolution No. 309 establishes accounting procedures to define the components of financial instruments, which constitute payments of principal and interest on the principal value for the purposes of classification of financial assets. It also establishes parameters to measure the expected loss associated with credit risk, including those for setting minimum levels of allowance for expected losses associated with credit risk, among other changes.

*[**Table of Contents**](#toc)*<br>

Meanwhile, on October 23, 2023, CVM issued Resolution No. 193, which provides that publicly listed companies in Brazil, such as us, investment funds and securitization companies must prepare and disclose, subject to certain requirements, financial information reports related to sustainability and climate in accordance with international standards (IFRS S1 and IFRS S2) issued by the International Sustainability Standards Board, or ISSB. The compliance with such standards became mandatory as of the fiscal year beginning on January 1, 2026.

Furthermore, on November 21, 2024, the CMN issued Resolution No. 5,185, which established the obligation for financial institutions to disclose the financial information report related to sustainability within their annual consolidated financial statement, in accordance with the International Accounting Standards Board (IASB) and the Brazilian Sustainability Pronouncements Committee (CBPS).

Resolution No. 193 came into effect on November 1, 2023, Resolution No. 5,185 on January 1, 2025, and Resolution No. 352 will come into effect on January 1, 2027 regarding Hedge Accounting.

On December 23, 2024, the CMN and the Brazilian Central Bank issued CMN Resolution No. 5,199 and Central Bank Resolution No. 448, which respectively amend CMN Resolution No. 4,996 and Brazilian Central Bank Resolution No. 352 to establish a transition schedule to incorporate the impacts on regulatory capital due to the new provisioning model set forth under those rules and based on IFRS 9. This transition schedule aligns with the Basel Committee on Banking Supervision (BCBS) recommendations, which allow jurisdictions to phase in the effects on regulatory capital resulting from increased provisions following the adoption of IFRS 9. The rule partially restores regulatory capital that may have been reduced due to the shift to the new provisioning model. The transition will take place from 2025 to 2028 and will apply to all institutions authorized by the Brazilian Central Bank that calculate regulatory capital, including us. This adjustment aims to ensure that the metrics for risk exposure are sensitively managed.

On November 4, 2025, the Brazilian Central Bank launched Public Consultation No. 127, proposing amendments to BCB Resolution No. 139/2021 to expand and standardize the Social, Environmental and Climate Risks and Opportunities Report (GRSAC). The proposal introduces a second phase of requirements focused on quantitative metrics and targets, while refining the qualitative tables adopted in 2021, and aligns disclosures with international standards, including IFRS S1 and S2 and the Basel Committee's Pillar 3 framework for voluntary climate risk disclosures. The new framework structures the GRSAC Report into standardized qualitative and quantitative tables covering governance, strategy, risk management and climate risk (transition and physical), as well as sectoral exposures and emissions, agriculture by biome, power generation by source, physical risk metrics for drought and heavy rain, transition plans, and social and environmental risk exposures. Disclosure of business opportunities remains voluntary; disclosure of national and international voluntary commitments follows new standardized tables (COMP1 and COMP2). The consultation also clarifies the use of climate scenario analysis, with parameters for narratives, time horizons and scientific bases.

Implementation is phased. For S1 and S2 institutions, the new GRSAC format would take effect in January 2027, with the first publication in 2028 using a December 2027 reference date. S3 institutions become subject to all tables with the first required publication based on December 31, 2028; S4 institutions, previously limited to a qualitative governance table, must disclose standardized information on social, environmental or climate commitments via COMP1 and COMP2 on the same timeline as S3. S5 institutions remain exempt. The proposed rules preserve flexibility to add granularity or justify omissions where immaterial and allow complementing tables to meet the sustainability financial reporting requirements aligned with IFRS, subject to consolidation scope differences. The public consultation remains open for comments until February 13, 2026.

***Segmentation for the Proportional Application of Prudential Regulation***

In 2017, the CMN enacted a resolution establishing segmentation for financial institutions, financial institution groups, and other institutions authorized to operate by the Brazilian Central Bank for the purposes of proportional application of the prudential regulation. The segmentation is based on the size, international activity and risk profile of members of each segment. Pursuant to the resolution, the segments are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• Segment 1 comprises multiservice banks, commercial banks, investment banks, foreign exchange banks and
savings banks with (a) an asset base equivalent or superior to 10% of Brazil's GDP; or (b) which perform relevant international
activities, irrespective of the size of the institution;

&nbsp;&nbsp;&nbsp;&nbsp;• Segment 2 comprises multiservice banks, commercial banks, investment banks, foreign exchange banks and
savings banks with (a) an asset base lower than 10% of Brazil's GDP; and (b) other institutions with an asset base equivalent to
or greater than 1% of Brazil's GDP;

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• Segment 3 comprises institutions with an asset base lower than 1% and equivalent to or greater than
0.1% of Brazil's GDP;

&nbsp;&nbsp;&nbsp;&nbsp;• Segment 4 comprises institutions with an asset base lower than 0.1% of Brazil's GDP; and

&nbsp;&nbsp;&nbsp;&nbsp;• Segment 5 comprises institutions with an asset base lower than 0.1% of Brazil's GDP, that apply
a simplified optional method for verifying the regulatory capital's minimum requirements, except for multiservice banks, commercial
banks, investment banks, foreign exchange banks and savings banks.

We have been categorized by the Brazilian Central Bank in segment 1, the highest level for application of regulation for banks in Brazil.

***Regulation of Risk and Capital Management Structure***

The rules enacted by the CMN and the Brazilian Central Bank provide that risk management must be conducted through an integrated effort by the relevant entity (i.e., not only must risks be analyzed on an individual basis, but financial institutions must also control and mitigate the adverse effects caused by the interaction between different risks). The rules set out different structures for risk and capital management, which are applicable for different risk profiles. This means that a financial institution of limited systemic importance can have a simplified structure of management, while institutions of larger complexity have to follow stricter protocols.

Furthermore, on June 29, 2023, the CMN issued Resolution No. 5,089, which introduces changes to risk management requirements applicable to financial institutions, such as us. Pursuant to the new rule, country and transfer risks will be considered autonomous risks. Under the new rule, country risk is defined as the possibility of losses associated or incurred due to events related to foreign jurisdictions and transfer risk as the possibility of occurrence of obstacles in the currency conversion of the funds required for the settlement of obligations towards the financial conglomerate if these funds are held in a jurisdiction other than that where the respective settlement will take place. The amendments introduced by Resolution No. 5,089 came into effect on January 1, 2024.

***Compulsory Reserve Requirements***

Currently, the Brazilian Central Bank imposes a series of compulsory reserves requirements. Financial institutions must deposit these reserves with the Brazilian Central Bank. The Brazilian Central Bank uses these reserve requirements as a mechanism to control the liquidity of the Brazilian financial system for both monetary policy and risk mitigation purposes. Reserves imposed on time deposits, demand deposits and saving accounts represent almost the entirety of the amount that must be deposited at the Brazilian Central Bank.

&nbsp;&nbsp;&nbsp;&nbsp;• *Time Deposits (CDBs)*, The Brazilian Central Bank imposes a reserve requirement of 20% in relation
to time deposits. Financial institutions must deposit an amount equivalent to the surplus of (i) R$3.6 billion for financial institutions
with consolidated Tier 1 capital under R$3 billion; (ii) R$2.4 billion for financial institutions with consolidated Tier 1 capital between
R$3 billion and R$10 billion; (iii) R$1.2 billion for financial institutions with consolidated Tier 1 capital between R$10 billion and
R$15 billion; and (iv) zero for financial institutions with a regulatory capital greater than R$15 billion.

Additionally, as from the issuing of Brazilian Central Bank Resolution No. 145 on September 24, 2021, collateral deposit for the new funding mechanism for financial institutions (called *Linhas Financeiras de Liquidez*) can be used to deduct up to three percentage points of this type of reserve requirement.

&nbsp;&nbsp;&nbsp;&nbsp;• *Demand Deposits*. As a general rule, the Brazilian Central Bank imposes a reserve requirement
of 21% in relation to demand deposits.

&nbsp;&nbsp;&nbsp;&nbsp;• *Savings Deposit* s. The Brazilian Central Bank imposes a reserve requirement of 20% in relation
to general savings deposits and to rural savings deposits.

***New Rules Applicable to the Perfection and Enforcement of In Rem Collateral***

On October 30, 2023, the President of Brazil enacted Bill of Law No. 4,188/2021, leading to the enactment of Law No. 14,711. This legislation brings about significant alterations to the Brazilian legal landscape concerning collateral, with the objective of enhancing legal certainty, reducing interest rates on secured loans, and expanding credit accessibility for borrowers. Its primary objective is to address the existing issue of immobilized capital in the fiduciary sale of real estate, where, prior to this legislation, a property could not be utilized as collateral more than once. Consequently, Law No. 14,711 implements adjustments to Brazilian civil law to tackle this issue, including: (i) permitting a new fiduciary sale over the same property; (ii) extending an existing guarantee to a new debt; and (iii) introducing the figure of the collateral agent into the Brazilian legal framework. Additionally, the new law incorporates various enhancements concerning the perfection and extrajudicial enforcement of collateral, including the modification and repeal of outdated laws, alterations to collateral registration regulations, among other measures.

**Asset Composition Requirements**

Permanent assets (defined as property and equipment other than commercial leasing operations, unconsolidated investments and deferred charges) of Brazilian financial institutions may not exceed 50% of their adjusted net equity, calculated in accordance with the criteria established by the Brazilian Central Bank.

Brazilian financial institutions, as a general rule, may not have more than 25% of their Tier 1 regulatory capital allocated to credit and leasing transactions and guarantees extended to the same customer or group of customers acting jointly or representing the same economic interest. In addition, Brazilian financial institutions must comply with an exposure limit of 25% of their regulatory capital in connection with underwriting for or investments in securities of the same entity, its affiliates, or controlled or controlling companies. Repurchase transactions executed in Brazil are subject to operational capital limits based on the financial institution's regulatory capital, as adjusted in accordance with Brazilian Central Bank regulations. A financial institution may carry out repurchase transactions in an amount of up to 30 times its regulatory capital. Within that limit, repurchase transactions involving private securities may not exceed five times the regulatory capital. Limits on repurchase transactions involving securities backed by Brazilian governmental authorities vary in accordance with the type of security involved in the transaction and the perceived risk of the issuer as determined by the Brazilian Central Bank.

The regulation issued by the Brazilian Central Bank with respect to the classification and valuation of securities and derivative financial instruments — including government securities — owned by financial institutions, based on the investment strategy of the financial institution, determined that securities and derivatives are to be classified into three categories: (i) trading; (ii) available for sale; and (iii) held to maturity.

"Trading" and "available for sale" securities are to be marked-to-market with effects in income and stockholders' equity, respectively. Securities classified as "held to maturity" are recorded at amortized cost, Derivatives are marked-to-market and recorded as assets and liabilities in the balance sheet. Changes in the market value of derivatives are generally recognized in income with certain modifications, if these are designated as hedges and qualify for hedge accounting under the regulations issued by the Brazilian Central Bank. Securities and derivatives in the "held to maturity" portfolio may be hedged for accounting purposes but their increase or decrease in value as derived from the marked-to-market accounting method should not be taken into account.

On July 31, 2018, the CMN enacted a rule providing that financial institutions categorized as "Segment 1" as per the Brazilian Central Bank's classification system established in 2017 (which is our case) (1) may not have more than 25.0% of their regulatory capital allocated to a single legal or natural person, and (2) that the total exposure of such financial institutions to one individual customer may not exceed 600% of their regulatory capital allocated to focused exposure, that is 10% of their Tier 1 regulatory capital. The rule also subjects financial institutions categorized as segment 2, segment 3 or segment 4 to less restrictive rules.

***Centralized Registration and Deposit of Financial Assets and Securities***

Law No. 13,476/17 consolidates the provisions on creation of liens over financial assets and securities, CMN Resolution No. 4,593/2017, as amended, regulates the registration and deposit of financial instruments and securities by financial institutions as well as the provision of custody services by such institutions.

Resolution No. 4,734/19 sets out the guidelines applicable to the establishment of liens and encumbrances on credit and debit payment instruments due to credit operations with financial institutions and regulates credit operations guaranteed by receivables from payment arrangements. The amount of receivables perfected into guarantees for a certain credit transaction will be reduced, whenever applicable, so that they are limited to the outstanding balance of the transaction or to the maximum limit extended, in the case of an extension of a non-dischargeable credit facility by a financial institution on an absolute and unilateral basis.

Resolution No. 264/22 deals in particular with the procedures for the registration of receivables and requires a convention between market infrastructures to guarantee the uniqueness of the receivables as financial assets that can be registered, interoperability, exchange of information between registration systems and participants in the structure. Resolution No. 264/22 came into effect on December 1, 2022.

*[**Table of Contents**](#toc)*<br>

Furthermore, on August 24, 2023, the CMN issued Resolution No. 5,094 and the Brazilian Central Bank issued Resolution No. 339, which establish changes related to the issuance, registration, centralized deposit and negotiation of book trade acceptance bills (duplicatas escriturais), such as the establishment of a new settlement system for book trade acceptance bills and the provision to establish a contestation procedure by the bookrunner companies, which must be uniform, documented and with a response period of three days, when referring to the services of the bookrunner companies themselves. In December 2024, a convention regarding the interoperability of the registration and bookkeeping systems applicable to book trade acceptance bills was signed by market participants. The system is expected to begin operating by the end of 2026.

Resolutions No. 5,094 and 339 came into effect on September 1, 2023.

***Brazilian Payment and Settlement System***

The rules for the settlement of payments in Brazil are based on the guidelines adopted by the Bank of International Settlements, or "BIS," and the current Brazilian Payment and Settlement System (*Sistema de Pagamentos Brasileiro* or the "SPB"). The Brazilian Central Bank and CVM (in relation to transactions with securities) have the power to regulate and supervise this system, SPB is composed of systems for the clearing of checks, clearing and settlement of debit and credit electronic orders, transfer of funds and other financial assets, clearing and settlement of transactions involving securities, clearing and settlement of transactions carried out in commodities and futures, and others, collectively designated as Financial Market Infrastructures, as well as the payment arrangements and payment institutions.

Within the scope of SPB, the Brazilian Central Bank operates the Reserves Transfer System, or "STR," and the SELIC. STR is a system of transfer of funds with real-time gross settlement, which means that transfers are made at the processing time, one by one, and are subject to the existence of outstanding balance in the account. STR is composed of financial institutions, clearing and settlement houses and the National Treasury Office. SELIC is the Brazilian Special Settlement and Custody System (*Sistema Especial de Liquidação e Custódia*), a system intended for custody of book-entry securities issued by the National Treasury Office and for the registration and settlement of transactions involving such securities.

***Instant Payment System***

The Brazilian Central Bank also implemented an instant payment ecosystem in November 2020. The settlement of the system is centralized at the Brazilian Central Bank. In addition to increasing the speed at which payments or transfers are made and received, available 24 hours a day, seven days a week in all days of the year, the ecosystem has the potential to increase market competitiveness and efficiency; lower costs; and enhance customer experience.

On March 3, 2022, the Brazilian Central Bank issued Resolution No. 195/22, which regulates the SPI. Resolution No. 195/22 also approved the regulation with which the direct and indirect participants in the SPI must comply and Brazilian Central Bank Normative Ruling No. 243/22 established the procedures and timetable for the tests necessary to register as a direct participant in the SPI.

According to the by-laws of the SPI, the participation in the SPI is mandatory for the participants of the PIX arrangement, and optional for (i) the clearinghouses and other providers of clearing services, and (ii) the National Treasury Department.

There are two types of participation in the SPI: (i) direct, in which the participant holds an instant payment account and is directly connected to the SPI; and (ii) indirect, in which the participant institution does not hold an instant payment account and its participation occurs via a direct participant to the SPI, responsible for registering the indirect participant in the SPI and to act as its clearing agent in the SPI for instant payments. Resolution No. 195/22 came into effect on April 1, 2022.

On August 12, 2020, the Brazilian Central Bank issued Central Bank Resolution No. 1, or "Central Bank Resolution No. 1/2020," establishing the PIX System payment arrangement and approving the regulation governing it, or (the "PIX Regulations").

Pursuant to Central Bank Resolution No. 1/2020, participation in the PIX System is mandatory for financial institutions and payment institutions authorized to operate by the Brazilian Central Bank that have more than 500,000 active customer accounts, considering cash deposit accounts, savings deposit accounts and prepaid payment accounts. Participation in the PIX System is optional for financial institutions and payment institutions that do not meet this threshold, as well as for the National Treasury Secretariat.

*[**Table of Contents**](#toc)*<br>

The PIX Regulation applies to all PIX System participants. According to the PIX Regulations, there are three types of participation: (i) transactional account provider, which is a financial institution or a payment institution that offers deposit accounts or payment accounts to end users; (ii) government entity, which is the National Treasury Secretariat, with the exclusive purpose of making collections and payments related to its activities; and (iii) special clearinghouses, that are the financial institutions and payment institutions that (a) within the scope of the PIX System, have the exclusive purpose of providing settlement services to other participants, (b) meet the requirements to act as settlement participant in the Brazilian Central Bank's SPI, and (c) do not meet the criteria of mandatory participation in the PIX System.

Brazilian Central Bank Resolution No. 1/2020 came into effect on September 1, 2020. PIX System transactions started operating on a restricted basis through to November 3, 2020, and was fully as of November 16, 2020.

Furthermore, on September 2, 2021, the Brazilian Central Bank issued Resolutions No. 135 and 136, which regulate the offering of the PIX Withdrawal and PIX Change services by regulated institutions that participate in the Brazilian Instant Payments System. Both rules came into effect on November 1, 2021. The new services were established by the Brazilian Central Bank on August 24, 2021, in a meeting of its Collegiate Board, which approved changes to the PIX Regulations.

PIX Withdrawal will allow all the customers of any participating institution to make a withdrawal in kind at one of the points that offer the service. Merchants, shared ATM networks and PIX participants, through their own ATMs, may offer the service. In order to withdraw funds in kind through PIX, the client simply executes a PIX transaction to the withdrawal agent, in a similar dynamic to a normal PIX transaction, by reading a QR Code or through the service provider's API.

With the PIX Change, the dynamic is almost identical. The difference is that the withdrawal of cash can be carried out during a purchase transaction with a merchant that offers PIX as a means of payment. In this case, the PIX transaction is executed for the total amount (purchase + cash withdrawal). The customer's invoice will show the amount corresponding to the cash withdrawal and the purchase amount.

The offer of the two new products on PIX's evolving agenda to users is optional, and the final decision to implement PIX Withdrawal and PIX Change is up to the merchants that accept PIX, the companies that own ATM networks, and the financial institutions that have their own ATMs.

Further, on September 23, 2021, the Brazilian Central Bank issued Resolution No. 142, introducing security measures to be adopted by institutions under its regulation and supervision to prevent frauds in the provision of payment services.

Resolution No. 142 establishes that financial and payment institutions must limit the provision of payment services for the period from 8 p.m. to 6 a.m. to a maximum of R$1,000 per deposit or prepaid payment account, as applicable. This limit may be increased at the client's request, which must be submitted formally through the relevant electronic service channels, but the institution must establish a minimum period of 24 hours for the change to take effect. Resolution No. 142 required payment service providers to implement the new transaction limit by October 4, 2021.

Pursuant to Resolution No. 142, financial and payment institutions should have implemented, by November 16, 2021: (i) procedures aimed at evaluating the customer prior to offering the anticipation of the settlement of payment receivables on the same date of the execution of a payment transaction within the scope of payment schemes in which the institutions participate; and (ii) daily registration of the occurrence of fraud or attempted fraud in the rendering of payment services, including the corrective measures adopted by the institution. Based on these records, the institutions must prepare a monthly report consolidating the occurrences and the preventive and corrective measures adopted. This report must be forwarded to the entity's audit and risk committees (if in place), internal audit unit, executive board and board of directors (if in place).

Furthermore, on September 28, 2021, the Brazilian Central Bank issued Resolution No. 147, which established security mechanisms specific to PIX transactions. The rule also details, within the scope of PIX, the measures established by Resolution No. 142, which applies to all electronic payment methods (including other types of electronic transfers available in Brazil, such as Transferência Eletrônica Disponível – TED or Documento de Ordem de Crédito – DOC). The security measures came into effect on November 16, 2021, with the exception of the new transaction limits, which came into effect on October 4, 2021. On September 26, 2023, the Brazilian Central Bank issued Resolution No. 342, which came into effect on September 28, 2023, and enhances rules mostly related to safety incidents involving PIX System. The rule mainly refers to communication to data subjects when any incidents involving personal data occurs, as well as the penalties that the institution participating in the PIX System are subject to in cases of noncompliance with technical and regulatory safety requirements.

*[**Table of Contents**](#toc)*<br>

On December 7, 2023, the Brazilian Central Bank issued Resolution Nos. 361, which amends the PIX sanctions manual to include provisions related to automatic PIX transactions, a new solution within the PIX ecosystem that will permit PIX payments in automatic installments, which may be used, for instance, in online subscription payments.

On July 22, 2024, the Brazilian Central Bank issued Resolution Nos. 402 and 403, aimed at improving the overall security of the PIX payment system. Pursuant to Resolution No. 402, the Central Bank changed the launch date of the Automatic PIX to June 16, 2025. This rule introduced the paying customer's consent (instead of previous authorization), a PIX rejection obligation in certain circumstances, and different application to the special mechanism for returning automatic PIX transactions. Furthermore, pursuant to Resolution No. 403, transactions can still be initiated from unregistered devices for amounts up to R$200, with a daily limit of R$1,000; however, for transactions that exceed these amounts, the device must be registered in advance by the customer. In addition, under the terms of Resolution No. 403, to further secure fund transactions, the Brazilian Central Bank mandates that PIX participants (such as us) implement a fraud risk management solution that uses security information from the Brazilian Central Bank to identify unusual transactions. In addition to the changes introduced by Resolution No. 403, PIX participants must also provide easily accessible information to customers about fraud prevention measures. Additionally, PIX participants are required to check every six months for fraud markings in the Brazilian Central Bank database, which will influence how they manage clients flagged for fraud risks. Both resolutions came into effect on November 1, 2024.

On September 25, 2025, CMN issued Resolution No. 5,251 and the Brazilian Central Bank issued Resolution No. 505, rules that imposed new requirements mandating that debit authorizations involving corporate or non-regulated payees comply with automated PIX standards, and obligating depositary and recipient institutions to revise their contracts and related operational procedures.

***Open Finance Regulation in Brazil***

On May 4, 2020, the Brazilian Central Bank and the CMN enacted Joint Resolution No. 1, which regulates open finance. Open finance consists of the sharing of data and payment initiation services and forwarding credit transaction proposals, by financial institutions and other authorized entities (with customers permission) and the integration of information systems, through a phased-in approach and in a secure, prompt, accurate and convenient manner.

Among other topics, the resolution sets forth the mandatory and voluntary participating institutions, the data and services covered, the requirements for sharing, the responsibilities for sharing, the implementation schedule and the form of agreement to be entered into by the participating institutions.

According to the resolution, (i) financial institutions and prudential conglomerates belonging to the S1 or S2 segments, as is our case, are mandatorily required to fully participate in open finance; and (ii) institutions offering current or payment accounts or payment initiation services are required to mandatorily participate in open finance at least in regards to the sharing of data related to payment initiation services.

On October 29, 2020, the Brazilian Central Bank issued Central Bank Resolution No. 32/2020, which sets forth the technical and operational requirements to be observed by institutions which participate in the Brazilian Open Finance System.

The new rule lays out, among others, rules relating to (i) the scope of the data and services to be shared by participating institutions within Open Finance, detailed in a specific manual; (ii) the standards for the development of application programming interfaces (APIs) by participating institutions, detailed in a specific manual, which deals with their design, data transmission protocols, data exchange formats, control accesses, version control systems and specification parameters; among other things; (iii) criteria for registration and cancellation of registration in Open Finance; (iv) services to be rendered by the Open Finance Governance Structure, which also is detailed in a specific manual, including the maintenance of a repository of participating institutions and a website containing updated information about Open Finance and its implementation; and (v) minimal security standards and certifications.

Additionally, on September 9, 2021, the Brazilian Central Bank published Resolution No. 138, which disclosed the minimum scope of data to be available for sharing on Stage 4 of Open Finance, to be further detailed by the Open Finance Governance Body. The fourth stage of the ecosystem, which covers data on foreign exchange, investment, insurance, and open-end private pension transactions, as well as merchant acquiring services, began on December 15, 2021, when the participating institutions must make the information about the mentioned products and services available to other financial institutions.

*[**Table of Contents**](#toc)*<br>

Regarding investment transactions, the main financial and capital market products offered in Brazil were included in the scope of Stage 4, such as: (i) Banking Time Deposit Certificates (*Certificados de Depósito Bancário* or CDBs); (ii) Banking Time Deposit Receipts (*Recibos de Depósito Bancário* or RDBs); (iii) Real Estate Credit Bills (*Letras de Crédito Imobiliário* or LCIs); (iv) Agribusiness Credit Bills (*Letras de Crédito do Agronegócio* or LCAs); (v) investment fund quotas; (vi) direct treasury government bonds (*títulos do tesouro direto*); (vii) stock; (viii) quotas of exchange-traded investment funds (ETFs); (ix) debentures; (x) Certificates of Real Estate Receivables (*Certificados de Recebíveis Imobiliários* or CRIs); and (xi) Certificates of Agribusiness Receivables (*Certificados de Recebíveis do Agronegócio* or CRAs).

With regard to foreign exchange transactions, effective total value of transactions (VET) and commercial exchange rates will need to be made available. The data referring to merchant acquiring services will cover applied service fees and rates.

Finally, the data referring to insurance products and pension plans will follow the scope defined by the CNSP and the SUSEP in CNSP Resolution No. 415/2021 and SUSEP Circular No. 635/2021, respectively, which establish a specific timeline for the implementation of Open Insurance, an exclusive governance body responsible for Open Insurance, as well as specific implementation manuals.

Phase 4 of Open Finance introduced information sharing beyond traditional banking products and services, marking the beginning of the migration from Open Banking to Open Finance in Brazil.

On October 26, 2023, the CMN and the Brazilian Central Bank issued Joint Resolution No. 7, which came into effect on October 30, 2023, and simplifies the process of renewing consents for data sharing in Open Finance. In order to ease the process for clients, the new rule allows participating institutions, such as us, to offer longer terms than the current 12-month limit for data sharing, while maintaining the provision permitting clients to revoke their consent at any time.

On July 5, 2024, the Brazilian Central Bank and the CMN introduced new open finance regulations aimed at enhancing payment transactions via the PIX system. The regulations (Joint Resolution No. 10 and Brazilian Central Bank Resolutions Nos. 398, 399, and 400) simplify payment initiation processes and facilitate contactless payments. Key changes include a new framework for governance and adjustments to mandatory participation requirements for institutions in the open finance ecosystem. The significant changes include the following: (i) payment initiation service institutions may provide services without redirecting users to different platforms, streamlining contactless payments and improving user experience; (ii) from January 1<sup>st</sup>, 2025 on, only institutions with over five million customers will be required to participate in data sharing within the open finance ecosystem, while smaller institutions will be able to opt in voluntarily; and (iii) for payment initiation services, participation will no longer be mandatory for all account-holding institutions; only payment initiation service providers and mandatory PIX participants (such as us) will need to be involved.

***Regulatory Sandbox***

On November 28, 2019, the Brazilian Central Bank published Public Consultation No. 72/2019, which ended on January 31, 2020, regarding the Controlled Testing Environment for Financial Innovations or "Sandbox" which is intended to enable institutions to test innovative financial and payment projects for a specified period.

After receiving comments on such Public Consultation, the CMN and the Brazilian Central Bank issued, on November 26, 2020, CMN Resolution No. 4,865/20 and BCB Resolution No. 29/20, to regulate the Sandbox. These rules set forth the applicable conditions for the implementation of the Sandbox, among which are the specific rules for the first cycle of tests, such as duration and number of participants, required documentation, criteria for the classification of institutions and the schedule for registration, selection and authorization processes of such entities. In November 2021, the Brazilian Central Bank selected developers' projects for the first cycle, which lasted for one year and was extended for a second year through November 2023. As of the date of this annual report, a second cycle still has not commenced.

***Treatment of Overdue Debts***

The Brazilian Central Bank requires financial institutions to classify credit transactions in accordance with their level of credit risk and to make provisions according to the level attributed to each transaction. Such credit classifications shall be determined in accordance with criteria set forth from time to time by the Brazilian Central Bank, relating to the conditions of the debtor and the guarantor and the transaction terms. Pursuant to CMN Resolution No. 4,966, there are several credit transactions involving the same customer, economic group or group of companies, the credit risk must be determined by analyzing the particular credit transaction of such customer or group that represents the greatest credit risk to the financial institution.

*[**Table of Contents**](#toc)*<br>

In accordance with the CMN Resolution No. 4,966, credit transactions may be classified either by the financial institution's own evaluation method or according to the number of days such transaction is past due, whichever is the more stringent. Credit classifications are required to be reviewed (i) monthly, in the event of a delay in the payment of any installment of principal or interest, in accordance with the maximum risk classifications; (ii) every six months, in the case of transactions involving the same customer, economic group or group of companies, the amount of which exceeds 5% of the adjusted net worth of the financial institution in question; and (iii) once every 12 months, in all circumstances not scheduled to be reviewed every six months.

The CMN and the Brazilian Central Bank established a transition schedule to incorporate the impacts on regulatory capital due to the new provisioning model set forth under those rules, based on IFRS 9. This transition schedule, expected to begin in December 2025 and end in January 2028, aligns with Basel III recommendations which allow jurisdictions to phase in the effects on regulatory capital resulting from increased provisions following the adoption of IFRS 9.

The provisions set forth above are not applicable to our IFRS consolidated financial statements, which are based on the criteria described under "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Critical Accounting Policies—Impairment Losses on Financial Assets."

***Regulation of the Transfer of Customer Data by Financial Institutions to Database Managers***

Brazilian law regulates the formation and consultation of databases with information regarding performance, individuals or legal entities, for the formation of credit history, Resolution No. 4,737 determines that the history of the following operations should be provided: (i) credit operations; (ii) leasing operations; (iii) self-financing operations executed upon consortium groups; and (iv) other operations with characteristics of credit granting; and defines the criteria for the registration of database managers, such as the identification of the natural and legal persons that are part of the control group of the database manager.

***Collection of Bank Fees***

Bank services to individuals are divided into the following four groups: (i) essential services; (ii) priority services; (iii) special services; and (iv) specific or differentiated services.

Banks are not able to collect fees in exchange for supplying essential services to individuals with regard to checking accounts, such as (i) supplying a debit card; (ii) supplying 10 checks per month to account holders who meet the requirements to use checks, as per the applicable rules; (iii) supplying a second debit card (except in cases of loss, theft, damage and other reasons not caused by the bank); (iv) up to four withdrawals per month, which can be made at a branch of the bank, using checks or in ATM terminals; (v) supplying up to two statements describing the transactions during the month, to be obtained through ATM terminals; (vi) inquiries over the internet; (vii) up to two transfers of funds between accounts held by the same bank, per month, at a branch, through ATM terminals or over the internet; (viii) clearing checks; and (ix) supplying a consolidated statement describing, on a month-by-month basis, the fees charged over the preceding year with regard to checking accounts and savings accounts.

Certain services rendered to individuals with regard to savings accounts also fall under the category of essential services and therefore are exempt from the payment of fees. CMN prohibits banks from charging fees for supplying essential services in connection with deposit and savings accounts where customers agree to access and use their accounts by electronic means only (being authorized to charge fees for supplying essential services only when the customer voluntarily elects to obtain personal service at the banks' branches or customer service locations).

Priority services are those rendered to individuals with regard to checking accounts, transfers of funds, credit transactions, leasing, standard credit cards, over-the-counter exchange transactions for the purchase or sale of foreign currency in respect of international travel, and records, and are subject to the collection of fees by the financial institutions only if the service and its nomenclature are listed in its regulations. Commercial banks must also offer to their individual customers a "standardized package" of priority services, whose content is defined, as well as the customers' option to acquire individual services instead of adhering to the package.

The collection of fees in exchange for the supply of special services (including, among others, services relating to rural credit, currency exchange market and on lending of funds from the real estate financial system) is governed by the specific provisions found in the laws and regulations relating to such services. The regulation authorizes financial institutions to charge fees for the performance of specific services, provided either that the account holder or user is informed of the conditions for use and payment or that the fee and charging method are defined in the contract.

*[**Table of Contents**](#toc)*<br>

It is worth pointing out: (i) the prohibition against charging fees in cases of adhesion contract amendments, except in the cases of asset replacement in leasing transactions, early liquidation or amortization, cancellation or termination; (ii) the prohibition against including services related to credit cards and other services not subject to fees in service packages that include priority, special and/or differentiated services; (iii) the requirement that subscription to service packages must be through a separate contract; (iv) the requirement that information given to the customer with respect to a service package must include the value of each service included in the package, the number of times that each service may be utilized per month, and the total price of the package; (v) the requirement that a customer's annual banking statement must separately identify default interest, penalties and other costs charged on loans and leasing transactions; (vi) the requirement that registration fees cannot be cumulatively charged; and (vii) the requirement that overdraft fees can be charged, at most, once over the course of 30 days.

In addition, CMN regulations establish that all debits related to the collection of fees must be charged to a bank account only if there are sufficient funds to cover such debits in such account and thus forbid overdrafts caused by the collection of banking fees. Furthermore, a minimum of 30 days' notice must precede any increase or creation of fees (except if related to credit card services, when a minimum of 45 days' notice is required), while fees related to priority services and the "standardized package" can be increased only after 180 days from the date of the last increase (except if related to credit card services, when a minimum of 365 days' notice is required) whereas reductions can take place at any time.

***Changes to Rules Applicable to Agribusiness Receivables Certificates, Real Estate Receivables Certificates and Other Incentivized Instruments***

On February 1, 2024, the CMN introduced changes to the eligible collateral for the issuance of agribusiness receivables certificates (certificados de recebíveis do agronegócio, or "CRA") and real estate receivables certificates (certificados de recebíveis imobiliários, or "CRI") through Resolution No. 5,118, dated February 1st, 2024. Similarly, through Resolution No. 5,119, also dated February 1st, 2024, the CMN made adjustments to eligible collateral and maturity periods for agribusiness credit letters (letras de crédito do agronegócio, or "LCA"), real estate credit letters (letras de crédito imobiliárias, or "LCI"), and guaranteed real estate letters (letras imobiliárias garantidas, or "LIG").

In relation to CRIs and CRAs, Resolution No. 5,118 prohibits that these certificates be backed by debt securities issued by (i) publicly held companies or related parties of such companies, unless the company's primary business activity is real estate (for CRI) or agribusiness (for CRA); and (ii) financial institutions or other institutions authorized by the Brazilian Central Bank, such as us. The following credit rights are also no longer eligible to back CRIs or CRAs: (i) transactions with related parties (e.g., lease agreements, sale & leaseback agreements within the same group); and (ii) credit rights arising from financial transactions used for expense reimbursement. These adjustments will apply to CRA and CRI issuances from the rule's publication date onwards and will not affect existing contracts.

Regarding LCAs, starting from July 1, 2024, Resolution No. 5,119 prohibits the use of funds raised through this instrument for rural credit benefiting from Brazilian federal subsidies. Additionally, the CMN now restricts the use of certain credit instruments as collateral, gradually limiting the use of controlled rural credit transactions in LCA collateral until July 1, 2025. The minimum maturity period for LCAs has been extended from 90 days to nine months to encourage longer-term funding.

In terms of LCIs, Resolution No. 5,119 also establishes acceptable real estate credit types as collateral, with a focus on actual real estate transactions, and extends the minimum maturity period for these instruments from 90 days to 12 months, aligning the maturity period with eligible collateral transactions. Similarly, rules applicable to LCIs are extended to LIGs to avoid double tax benefits without new real estate credit origination. These adjustments will apply to LCI and LIG issuances from the CMN's decision onwards, with existing contracts unaffected by the changes.

Both resolutions came into effect on February 2, 2024, with the exception of the prohibition of the use of proceeds from LCA issuances for rural credit benefiting from Brazilian federal subsidies, which came into effect on July 1, 2024.

***Late Payment Fees***

The default payment fees charged by financial institutions, consumer credit companies (*financeiras*) and leasing companies are expressly limited to compensatory interest per day on the amount that is overdue, interest on arrears and fines on arrears.

***Credit Cards***

The banking regulations also have specific rules relative to the charging of credit card fees, the publication of information in the card invoices and the obligation to provide a package of basic services upon offering credit cards to customers.

Revolving credit for financings of credit card bills may only be extended to customers until the due date of the following credit card bill. After this term, financial institutions offer customers another product with conditions more favorable than the ones typically found in the credit card market. Banks are prohibited from offering this type of credit to customers who have already contracted one revolving credit for financing of credit card bills which were not repaid in a timely manner.

Furthermore, Law No. 14,690 was promulgated on October 3, 2023. This law limits the interest rates charged on revolving credit provided in connection with credit cards and other post-paid instrument invoices and ratifies the emergency program for renegotiation of debts of individuals in default depending on the debtor's category, which in turn depends on the size of the debtor's debt (*Desenrola Brasil*). In light of the changes introduced by this rule, the CMN and the Brazilian Central Bank issued Resolution No. 5,112 and Resolution No. 365, respectively, on December 21, 2023, establishing: (i) that from January 3, 2024, interest and other financial fees charged over the financing of the outstanding balance of credit card and other post-paid instrument invoices may not exceed the principal amount of the financed debt; (ii) rules related to the portability of credit transactions granted in the context of post-paid payment instrument financings (such as credit cards); and (iii) transparency and financial education measures to be adopted by financial and payment institutions.

***Payment Agents and Payment Arrangements***

The regulation issued by the Brazilian Central Bank, determines, among other aspects: (i) consumer protection, anti-money laundering compliance and risk prevention systems that should be observed by payment agents and payment arrangers; (ii) the procedures for incorporation, organization, authorization and operation of payment agents, as well as transfer of shareholding control, subject to the Brazilian Central Bank's prior approval; (iii) capital requirements; (iv) definition of arrangements excluded from the SPB; and (v) rules related to payment accounts, which are divided into prepaid and postpaid accounts and require the allocation of the totality of their balance to a special account at the Brazilian Central Bank or investment in government bonds.

On September 2, 2024, the Brazilian Central Bank launched Public Consultation No. 104 to develop regulations aimed at strengthening centralized risk management frameworks within SPB. The consultation proposes amendments to Brazilian Central Bank Resolution No. 150, of October 2021, focusing on enhancing and standardizing risk management practices across payment networks. In addition to risk management, the new regulations will address concerns related to money laundering, terrorist financing, and the proliferation of weapons of mass destruction. Key proposals in the public consultation include the implementation of centralized settlement systems for sub-acquirers by January 1, 2027, and mandatory risk management elements such as periodic assessments and regular sharing of risk-related information among participants. The Brazilian Central Bank has outlined measures for managing financial risks through stress tests and backtesting, as well as rules ensuring that authorized transactions are fully paid to the end users. Additional responsibilities are placed on acquirers regarding the risk management of transactions processed through sub-acquirers, and new regulations addressing fraud prevention, orderly exit plans, and chargeback liability will also be introduced. According to the proposed rule, payment scheme arrangers (card networks) will have 180 days post-regulation publication to seek authorization for necessary adjustments.

On November 10, 2025, the Brazilian Central Bank issued BCB Resolution No. 522, which amends BCB Resolution No. 150/2021 and implements rules resulting from Public Consultation No. 104. The new framework strengthens centralized risk management in payment schemes that are part of the SPB, expressly allocating to the payment scheme settlor (networks) ultimate and non-derogable liability to ensure the settlement of all transactions to receiving users, including with its own funds if adopted protection mechanisms are insufficient. Resolution No. 522 enhances transparency over risk allocation and financial risk mitigation tools, and bars delegation of sub-acquirer oversight: the settlor (network) becomes solely responsible for monitoring participants' risks and may not delegate sub-acquirer risk management to acquirers. It also reinforces "honor all cards," prohibits the requirement of collaterals among participants, limits participants' financial liability in chargebacks to 180 days from the transaction authorization (after which, where rules permit, liability shifts to the network), and strengthens controls on fraud, AML/CFT, as well as conduct standards with payers. The rule further advances interoperability, information sharing, authorization/change/cancellation processes for arrangements, full participation of sub-acquirers in centralized clearing and settlement, and transparency of fees charged within arrangements.

*[**Table of Contents**](#toc)*<br>

Resolution No. 522 became effective upon publication (November 12, 2025). In view of the structural changes to risk management, scheme settlors must, within 180 days of publication, (i) submit to the Brazilian Central Bank requests for authorization to amend the regulations of their payment schemes to reflect the new requirements and (ii) implement the full participation of all sub-acquirers in centralized settlement for schemes subject to centralized settlement, along with related operational interfaces (including information exchange between settlement infrastructures and receivables registries) and enhanced tariff and penalty disclosures.

***Portability of Credit Transactions***

Financial institutions' customers can transfer their credit transactions from one institution to another. Such transfers must comply with the specific rules established by the Brazilian Central Bank, including, among others, the requirement that the amount and term of the transaction in the receiving financial institution must not be higher than the amount due and term of the original transaction.

***Digitalization of Documents and Record Keeping***

Financial institutions and other institutions authorized to operate by the Brazilian Central Bank may keep in their records digital documents instead of physical documents, provided that certain requirements to ensure the documents' authenticity and validity are met.

***Anti-Money Laundering Regulations***

Under the Brazilian Anti-Money Laundering Law, it is a crime to conceal or dissimulate the nature, origin, location, availability, transaction or ownership of assets, rights or amounts resulting, directly or indirectly, from any criminal offense, as well as their use in economic or financial activity and to participate in a group, association or office while being aware that its principal or secondary activities are directed toward the practice of such acts.

The Brazilian Anti-Money Laundering Law also created the Financial Activities Control Council (*Conselho de Controle de Atividades Financeira*s or "COAF"), which operates under the jurisdiction of the Ministry of Finance. The purpose of the COAF is to investigate, examine, identify and impose administrative sanctions in respect of any suspicious occurrences of illicit activities related to money laundering in Brazil.

The COAF is composed of individuals with recognized competence in this area, appointed by the Minister of Finance, all of whom are nominated by each of the following entities: (i) the Brazilian Central Bank; (ii) the CVM; (iii) the SUSEP; (iv) the Brazilian Treasury Attorney General's Office; (v) the Brazilian Federal Revenue; (vi) the Federal Intelligence Agency; (vii) the Ministry of Foreign Affairs; (viii) the Ministry of Justice; (ix) the Federal Police Department; (x) the Ministry of Social Security; and (xi) the General Comptroller's Office, one of whom will be the president, which shall be appointed by the President of Brazil on the basis of recommendations by the Minister of Finance.

Financial institutions must maintain specific records of (i) the transactions in cash (deposit, withdrawal, withdrawal by means of a prepaid card or request of provision for withdrawal) so as to enable the identification of a deposit in cash, withdrawal in cash, withdrawal in cash by means of a prepaid card, or request of provision for withdrawal, of (a) an amount equal to or greater than R$100,000.00 or (b) that presents evidence of concealment or dissimulation of the nature, of the origin, of the location, of the disposal, of the movement or of the ownership of assets, rights and valuables; and (ii) the issuances of cashier's checks, funds electronic transfers (TED) or of any other instrument of transfer of funds upon payment in cash, for an amount equal to or greater than R$100,000.00.

Financial institutions must maintain records of all transactions, products and services contracted, including withdrawals, deposits, contributions, payments, receipts and transfers of funds. Additionally, the institutions must also keep specific records of (i) transactions in cash with an individual value greater than R$2,000.00; (ii) deposit or cash transactions of an individual value equal to or greater than R$50,000.00; and (iii) withdrawal transactions, including those carried out by check or money order, with an individual value equal to or greater than R$50,000.00.

*[**Table of Contents**](#toc)*<br>

The regulations also impose an obligation on financial institutions to request that both customers and non-customers are providing a withdrawal request at least three working days in advance for withdrawals (including those carried out by check or money order) in an amount equal to or greater than R$50,000.00.

On January 23, 2020, the Brazilian Central Bank published Circular No. 3,978, which improves the regulation applicable to financial institutions, by expanding the adoption of a risk-based approach and came into effect on July 1, 2020. Regulated institutions must carry out specific internal risk assessments in order to identify and measure the risk of using their products and services in the practice of money laundering and terrorist funding.

In connection with the aforementioned change, the know-your-client, or "KYC" procedures were also improved and include the identification, qualification and classification of the customer, compatible with the risk profile, the nature of the relationship with the AML policy and the institution's internal risk assessment, which must be permanently reassessed, according to the evolution of the business relationship and the risk profile of the client. The procedures must also include the verification of the client's (including their representatives', family members' or close collaborators) condition as a Politically Exposed Individual, as well as consider them in the monitoring, selection and analysis of transactions and situations with indications of suspected money laundering or terrorist funding.

On July 27, 2021, the Brazilian Central Bank published Resolution No. 119, which came into effect on September 1, 2021, and introduced certain changes to Circular No. 3,978/2020, which establishes the regulations and procedures related to anti-money laundering and combating the financing of terrorism applicable to entities subject to the Brazilian Central Bank's regulation and supervision.

Among other changes brought by the new rule, financial institutions (and other entities regulated by the Brazilian Central Bank) are now required to obtain information about their customers' place of residence, in the case of a natural person, or the location of the head office or branch, in the case of a legal entity, as part of their mandatory KYC procedures. The CVM also issued CVM Resolution No. 50 on August 31, 2021, which establishes the framework for the prevention of money laundering and the financing of terrorism in the Brazilian securities market. CVM Resolution No. 50 is in line with the practices currently implemented in the principal global securities markets, including with regard to the recommendations of the Financial Action Group against Money Laundering and the Financing of Terrorism (GAFI/FATF), as well as with the duties arising from Brazilian anti-money laundering laws.

In 2023, the CMN and the Brazilian Central Bank issued Joint Resolution No. 6 and Resolution No. 343, which established the obligation for financial institutions such as us and other entities authorized by the Brazilian Central Bank to share among each other information about frauds occurred within the National Financial System, and the SPB, subject to the customer's prior contractual consent. The rule aims to reduce the asymmetry of data and information faced by these institutions to support procedures and controls in their fraud prevention processes, as well as improve their practices. Both resolutions came into effect on November 1, 2023.

The Brazilian Central Bank and the CMN have also recently adopted new measures that intensify controls over fraud prevention and the integrity of banking and payment accounts. These measures require institutions to reject certain payment transactions linked to suspected fraudulent accounts and to terminate accounts used for unauthorized financial or payment services or where grave customer-information irregularities are identified.

On September 11, 2025, the Brazilian Central Bank issued Resolution No. 501, establishing that Brazilian financial institutions and licensed payment institutions must reject payment transactions destined to demand deposit, savings, or prepaid payment accounts where there is a well-founded suspicion of fraud, with the receiving institution required to notify the account holder of the measure. Institutions may determine suspicion using their own factors and data sources, including public or private databases.

In addition, Brazilian Central Bank Resolution No. 518, of November 3, 2025, amends the framework for opening, maintaining, and closing payment accounts by mandating account closure where there are grave irregularities in customer information or where the account is used by the holder to provide financial or payment services within the Brazilian Financial System or Payments System without legal basis or in noncompliance with applicable regulations. The rule provides a non-exhaustive example covering the use of payment account funds to make or receive payments, or to settle obligations, on behalf of third parties in a manner that could conceal or substitute third-party obligations and prevent their identification. Institutions must adopt and board-approve internal criteria for such determinations, may rely on public or private databases, and must retain related documentation for at least 10 years.

Similarly, for deposit accounts, CMN Resolution No. 5,261, of November 3, 2025, amends the core deposit account framework to require closure where there are grave irregularities in customer information or where the holder uses the account to provide unauthorized financial or payment services within the Brazilian systems referenced above. As with payment accounts, the rule identifies as an example the use of deposit account funds for payments, receipts, or netting of obligations on behalf of third parties in a manner that may conceal or substitute third-party obligations and impede identification. Institutions must establish internal criteria, obtain board approval, and maintain related documentation for at least 10 years.

*[**Table of Contents**](#toc)*<br>

***Brazilian Anticorruption Law***

Law No. 12,846/13 of August 1, 2013, or the "Brazilian Anticorruption Law" establishes that legal entities will have strict liability regardless of fault or willful misconduct for acts against the public administration carried out in their interest or for their benefit. The Law encompasses not only performance of acts of corruption but also performance of other injurious acts contrary to the Brazilian or foreign public administration.

Corporations that violate the Brazilian Anticorruption Law's provisions will be subject to heavy penalties, some of which may be imposed through administrative proceedings and others solely through judicial channels. The Brazilian Anticorruption Law also creates a leniency program under which self-disclosure of violations and cooperation by corporations might result in the reduction of fines and other sanctions.

***Politically Exposed Individuals***

Financial institutions and other institutions authorized by the Brazilian Central Bank to operate must take certain actions and have certain controls in order to establish business relationships with and to follow up on the financial transactions of customers who are deemed to be politically exposed individuals (public agents and their immediate family members, spouses, life partners and stepchildren who occupy or have occupied a relevant public office or position over the past five years in Brazil or other countries, territories and foreign jurisdictions). The internal procedures developed and implemented for this purpose by financial institutions must be structured in such a way as to enable the identification of politically exposed individuals, as well as the origin of the funds involved in the transactions of such customers. One option is to verify the compatibility between the customer's transactions and the net worth stated in such customer's file.

***Bank Secrecy***

Brazilian financial and payment institutions shall also maintain the secrecy of their banking operations and services provided to their customers. The only circumstances in which information about customers, services or transactions of Brazilian financial and payment institutions may be disclosed to third parties are the following:

&nbsp;&nbsp;&nbsp;&nbsp;• the disclosure of information with the express consent of the interested parties;

&nbsp;&nbsp;&nbsp;&nbsp;• the exchange of information between financial institutions for record purposes;

&nbsp;&nbsp;&nbsp;&nbsp;• the supplying to credit reference agencies of information based on data from the records of issuers
of bank checks drawn on accounts without sufficient funds and defaulting debtors; and

&nbsp;&nbsp;&nbsp;&nbsp;• the occurrence or suspicion that criminal or administrative illegal acts have been performed, in which
case the financial institutions and the credit card companies may provide the pertinent authorities with information relating to such
criminal acts when necessary for the investigation of such acts.

Complementary Law No. 105/01 also allows the Brazilian Central Bank or the CVM to exchange information with foreign governmental authorities, provided that a specific treaty has previously been executed.

The governments of Brazil and the United States executed an agreement in 2007, by means of which these governments established rules for the exchange of information relating to tax, or the "2007 Agreement." Under the 2007 Agreement, the Brazilian tax authority would be able to send information it receives by virtue of Section 5 of the Bank Secrecy Law to the U.S. tax authority.

***Data Protection Requirements***

*Brazil*

The LGPD (*Lei Geral de Proteção de Dados)* was published in the Federal Official Gazette on August 15, 2018, and was amended by Law No. 13,853/19. The LGPD came into effect in September 2020, except for its administrative sanctions, which came into effect on August 1, 2021, pursuant to Law No. 14,010/20, which delayed the applicability of certain provisions of the LGPD.

*[**Table of Contents**](#toc)*<br>

Before the LGPD, Brazil lacked regulations specific to data privacy and a data protection authority. Despite this, privacy has been generally protected through the Brazilian Federal Constitution, the Civil Code (Law No. 10,406/2002), the Consumer Protection Code (Law No. 8,078/1990) and the Civil Rights Framework for the Internet (Law No. 12,965/2014 and the Decree No. 8,771/2016).

The LGPD brought about profound changes in the rules and regulations applicable to the processing of personal data, with a set of rules to be complied with in activities such as the collection, processing, storage, use, transfer, sharing and erasure of information concerning identified or identifiable natural persons.

The LGPD has a wide range of applications and extends to individuals as well as private and public entities, regardless of the country where they are headquartered or where data are hosted, as long as (i) the data processing takes place in Brazil; (ii) the data processing activity is intended to offer or supply goods or services to, or to process data of individuals located in Brazil; or (iii) the data subjects are located in Brazil at the time their personal data are collected. The LGPD will apply irrespective of the industry or business when dealing with personal data and is not restricted to data processing activities performed through digital media and/or on the internet.

The LGPD sets out several rules related to data processing such as principles, requirements and duties imposed to data controllers and data processors; rights of data subjects; requirements in connection with cross-border transfers of data; the obligation to appoint a data protection officer; data security and data breach notification; corporate governance practices; and the regime for civil liabilities and penalties in case of a breach of the provisions of the LGPD. Additionally, the ANPD has also issued additional regulation on several subjects, such as security incident reporting, cross-border transfers and the data protection officer rule.

Violation of the LGPD or ANPD resolutions may result in administrative penalties (in addition to civil liabilities), including among others (i) warnings; (ii) fines up to 2% of the revenue of the company, group or conglomerate in Brazil in the last financial year, capped at R$50.0 million per offense, (iii) daily fines; (iv) disclosure of the offense; (v) blocking of the personal database to which the offense refers, until the processing activity is corrected; (vi) elimination of the personal data to which the offense refers; (vii) partial or total suspension of the operation of the database to which the offense refers for a maximum period of six months, extendable for the same period; (viii) suspension of the processing of personal data to which the infringement refers for a maximum period of six months, extendable for the same period; and (ix) partial or total prohibition of the performance of any activities relating to data processing. Any administrative sanctions will be applied in accordance with Resolution CD/ANPD No. 4/2023. Determining the applicable sanction will depend on: (i) the gravity of the infraction being classified as "light," "medium" or "high"; and (ii) the ANPD's understanding of the proportionality of the sanction in relation to the infraction committed.

In addition, other authorities in Brazil can apply the LGPD through administrative procedures or lawsuits. The Department of Consumer Protection and Defense (PROCON) or the Brazilian Public Federal Prosecutor's Office (*Ministério Público Federal*) responsible for consumer rights, and individuals and nongovernmental or private associations, for example, could file complaints or bring lawsuits based on violations of the LGPD that have caused or may cause harm to individuals.

Moreover, Law No. 13,853/2019 created the ANPD, which has powers and responsibilities analogous to the European data protection authorities, exercising a triple role of (i) investigation, comprising the power to issue norms and procedures, deliberate on the interpretation of the LGPD and request information of controllers and proceedings; (ii) enforcement, in cases of noncompliance with the law, through an administrative process; and (iii) education, with the responsibility to disseminate information about and foster knowledge of the LGPD and security measures, fostering standards for services and products that facilitate control of data, and elaborating studies on national and international practices for the protection of personal data and privacy, among others.

The ANPD is a government agency subordinated to the Brazilian Ministry of Justice and Public Safety. It is composed of five commissioners, appointed by the President of Brazil, and advised by a National Council for the Protection of Personal Data and Privacy, composed of 23 unpaid members.

*[**Table of Contents**](#toc)*<br>

*Other*

In addition, we are subject to Regulation (EU) 2016/279 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (the "General Data Protection Regulation" or "GDPR"). The GDPR has also introduced new fines and penalties for a breach of requirements, including fines for systematic breaches of up to the higher of 4% of annual worldwide turnover or €20 million, and fines of up to 2% of annual worldwide turnover or €10 million (whichever is highest) for other specific infringements. Additionally, following the United Kingdom's withdrawal from the EU, we also are subject to the UK General Data Protection Regulation ("UK GDPR") (i.e., a version of the GDPR as implemented into United Kingdom law). While the UK GDPR has previously imposed substantially the same obligations as the GDPR, the UK GDPR will not automatically incorporate changes to the GDPR going forward (which would need to be specifically incorporated by the United Kingdom government). Moreover, the UK Data (Use and Access) Act, which makes several modifications to United Kingdom data protection law, received Royal Assent and came into being on June 19, 2025. These changes deviate from the GDPR and permit further deviations in the form of regulatory guidance or secondary legislation, which creates a risk of divergent parallel regimes and related uncertainty, along with the potential for increased compliance costs and risks for affected businesses.

***Regulations on Cybersecurity***

Financial institutions must follow certain cyber risk management and cloud outsourcing requirements which apply to the design and adaptation of internal controls, namely CMN Resolution No. 4,893/2021, which requires financial institutions to institute a Cybersecurity Policy, as well as regulates the outsourcing of relevant data processing and storage and cloud computing services and CVM Ruling No. 35/2021, which sets forth the standards and procedures to be observed in security transactions carried out in regulated securities markets requiring the implementation of cybersecurity controls and data protection. Policies and action plans to prevent and respond to cybersecurity incidents were fully compliant and in place by December 2021. Data location and processing may occur inside or outside Brazil, but access to data stored abroad must be granted at all times to the Brazilian Central Bank for inspection purposes. The contracting of relevant processing services must be communicated to the Brazilian Central Bank within 10 days from the execution of the agreement. See "Item 3. Key Information—D. Risk Factors— Risks Relating to the Brazilian Financial Services Industry and Our Business—Failure to adequately protect ourselves against risks relating to cybersecurity could materially and adversely affect us. We are also subject to increasing scrutiny and regulation governing cybersecurity risks" and "Item 16K. Cybersecurity."

***Auditing Requirements***

The legislation and regulations issued by the CMN, CVM and B3 determine that the periodic financial statements of financial institutions must be audited by independent auditors (individuals or legal entities) that are registered with the CVM and who meet the minimum requirements set forth by the Brazilian Central Bank, and that the financial statements must be presented together with an independent auditor's report. Our financial statements are audited in accordance with International Standards on Auditing with regard to Brazilian GAAP and also with the standards of the Public Company Accounting Oversight Board with regard to IFRS as issued by the IASB, as required by the SEC. For purposes of the financial statements prepared according to Brazilian GAAP, from 2017, all financial institutions and other institutions authorized to operate by the Brazilian Central Bank are required to create provisions for all losses related to financial guarantees issued by them. As a result of the auditing work, the independent auditor must prepare the following reports: (i) an audit report, issuing an opinion regarding the accounting statements and the respective explanatory notes, including regarding the compliance with financial regulations issued by the CMN and the Brazilian Central Bank; (ii) an internal control system quality and adequacy evaluation report, including regarding electronic data processing and risk management systems, evidencing any identified deficiencies; (iii) a legal and regulatory provisions noncompliance report, regarding those which have, or may have, material impacts on the financial statements or on the audited financial institution's operations; (iv) a limited assurance report, analyzing our Annual and Sustainability Report pursuant to the guidelines and requirements of the Global Reporting Initiative, or "GRI"; and (v) any other reports required by the Brazilian Central Bank, CVM and B3. The reports issued by independent auditors must be available for consultation upon request by the overseeing authorities.

As determined by CMN Resolution No. 4,910 of May 27, 2021, independent auditors and the audit committee, individually or jointly, must formally notify the Brazilian Central Bank of the existence or evidence of error or fraud, within three business days of the identification of the respective occurrence, including:

&nbsp;&nbsp;&nbsp;&nbsp;• noncompliance with legal rules and regulations that place the continuity of the audited entity at risk;

&nbsp;&nbsp;&nbsp;&nbsp;• frauds of any amount perpetrated by the management of the institution;

&nbsp;&nbsp;&nbsp;&nbsp;• material frauds perpetrated by the institution's employees or third parties; and

&nbsp;&nbsp;&nbsp;&nbsp;• errors that result in major incorrectness in the financial statements of the audited entity.

*[**Table of Contents**](#toc)*<br>

The executive officers of the financial institution must notify the independent auditor and the audit committee if any of the above situations occur. In addition, under the terms of CMN Resolution No. 4,910, the audit committee, when installed, the independent auditor and the internal audit must maintain an immediate communication routine with each other when the situations mentioned above are identified.

CMN Resolution No. 4,910 also requires financial institutions and institutions authorized to operate by the Brazilian Central Bank, which: (i) are registered as publicly-held companies (such as us); and/or (ii) are leaders of a prudential conglomerate or are classified in Segment 1 (S1), Segment 2 (S2) or Segment 3 (S3) (such as us) to create a corporate body designated as the "audit committee," which we have created. For more information on our audit committee, see "Item 6. Directors, Senior Management and Employees—C. Board Practices—Board Advisory Committees—Audit Committee."

***Internal Auditing of Financial Institutions***

Financial institutions are required to establish and maintain internal audit activities compatible with their operational specifications, so that such internal bodies are able to perform an independent, autonomous and impartial audit of the quality and effectiveness of the institution's internal systems. Such unit shall be directly controlled by the institution's board of directors. Internal and external independent auditors are also liable for failures of the financial institution's internal control mechanisms.

***Sustainability Requirements Applicable to Financial Institutions***

Financial institutions are currently required by CMN Resolution No. 4,327/14 to have a responsibility policy, which must guide the social and environmental actions in conducting their businesses, their relationship with their customers and other users of their products and services. The responsibility policy must also guide the financial institution's relationship with its personnel and with any others affected by the financial institution's activities. In addition, the responsibility policy must provide for the management of social and environmental risks (which, according to the Brazilian Central Bank, represent one of the several categories of risk to which financial institutions are exposed).

Following Public Consultations Nos. 82, 85 and 86, initiated by the Brazilian Central Bank in 2021 under the "Sustainability" pillar of the "Agenda BC#" (which consists of a list of goals to improve the Brazilian National Financial System), a new set of rules was published on September 15, 2021. These new rules aim to improve the disclosure of information, management and governance of social, environmental and climate risks by financial institutions, as well as to bring changes to the rural credit regulations in effect.

Resolution No. 140 establishes new conditions for the access to rural credit considering social, environmental and climatic aspects. Among them, it stands out the credit restriction for a producer who is not registered, or whose registration is canceled, in the Rural Environmental Registry (*Cadastro Ambiental Rural*). The new resolution also sets forth that rural credit shall not be granted to (i) an enterprise fully or partially inserted in a conservation unit, indigenous land already approved, an area of embargo in force resulting from the economic use of illegally deforested areas in the Amazon; nor (ii) an individual or legal entity registered in the official register of employers who have kept workers in conditions analogous to slavery.

CMN issued Resolution No. 4,943, which amended CMN Resolution No. 4,557/17 with the purpose of highlighting and distinguishing social, environmental and climate risks, as necessary for the identification, measurement, evaluation, monitoring, reporting, control and mitigation in connection with the risk management structure of financial institutions. The new rule provides for specific definitions to such risks, using new and modern concepts, such as the inclusion of the two main components of climate risks – physical and of transition – already recognized by international sustainability standards. The amended rule also deals with the identification and monitoring of social, environmental and climate risks incurred by financial institutions, resulting not only from their products, services and activities, but also from the activities performed by their counterparties, controlled entities, suppliers and outsourced service providers.

Similar provisions were also included in the simplified structure of continuous risk management pertaining to the Simplified Reference Capital (*Patrimônio de Referência Simplificado*) by the new CMN Resolution No. 4,944, which amends CMN Resolution No. 4,606.

The CMN issued Resolution No. 4,945, replacing CMN Resolution No. 4,327 of April 25, 2014 on the Social and Environmental Responsibility Policy (*Política de Responsabilidade Socioambiental*), or the "PRSA." The new rule provides for the inclusion of a climate aspect to the PRSA, which we refer to as the PRSAC. Such new policy to be implemented by financial institutions shall take into account the impacts, strategic goals and business opportunities for the financial institutions in connection with social, environmental and climate aspects. There was also a reduction in the period for reviewing the PRSA, from five to three years.

*[**Table of Contents**](#toc)*<br>

The Brazilian Central Bank issued Resolution No. 139, regulating the preparation of a Report on Social, Environmental and Climate Risks and Opportunities (*Relatório de Riscos e Oportunidades Sociais, Ambientais e Climáticas*, or the "GRSAC Report") by financial institutions classified in S1 (such as us), S2, S3 or S4. Following the propositions of the Public Consultation, this new rule seeks to contemplate the recommendations of the Task Force on Climate-related Financial Disclosures at the national regulatory level. The GRSAC Report must be published annually with the base date of December 31, within a maximum period of 90 days from December 31, and must be made available on the financial institutions' websites for a period of five years.

Finally, on October 6, 2021, the Brazilian Central Bank published Resolution No. 151, which regulates the remittance information regarding social, environmental, and climate risks addressed in CMN Resolution No. 4,557 and CMN Resolution No. 4,945 to the Brazilian Central Bank by authorized institutions. The rule applies to institutions classified in segments S1 (such as us), S2, S3, or segment four, or "S4"; and the information that must be sent to the Brazilian Central Bank is related to the assessment of social, environmental and climate risks related to their exposures in credit and securities transactions, as well as those of the respective debtors under these transactions. The information to be remitted includes identification, economic sector, risk aggravating and mitigating factors, appraisal of social, environmental and climate risks, among others.

In order to allow financial institutions to adapt their practices and policies to this new set of rules, CMN Resolution No. 4,943/21 and general provisions of CMN Resolution No. 4,945/21 came into effect on July 1, 2022, CMN Resolution No. 4,944/21, article 16 of CMN Resolution No. 4,945/21 (which revokes CMN Resolution No. 4,327/14) and Central Bank Resolution No. 139/21 came into effect on December 1, 2022. Brazilian Central Bank Resolution No. 151 came into effect on July 1, 2022 and Central Bank Resolution No. 140, which specifically provides for rural credit, came into effect on October 1, 2021.

On November 21, 2024, the CMN issued Resolution No. 5,185, which requires larger financial institutions to prepare and disclose, along with their financial statements, a report of financial information related to sustainability, in accordance with (i) the International Sustainability Standards Board's IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) pronouncements and (ii) the Brazilian Sustainability Pronouncements Committee's (CBPS) Technical Pronouncement 01 and 02, on the same matters. The preparation and disclosure of the report is mandatory for institutions that disclose consolidated annual financial statements following the international accounting standard of the International Accounting Standards Board (IASB), including publicly traded companies and leaders of prudential conglomerates in the S1, S2 or S3 segments, such as us. Thus, institutions that voluntarily publish consolidated financial statements must also disclose the sustainability report, which must be ensured by an independent auditor. Resolution No. 5,185 came into force on January 1, 2025 and the disclosure obligation begins in 2026 for institutions registered as a publicly held company or in the S1 or S2 segments, and in 2028 for institutions in the S3 segment and those that voluntarily publish consolidated financial statements, with early voluntary adoption allowed.

A presidential decree issued on October 31, 2025 established the Brazilian Sustainable Taxonomy (Taxonomia Sustentável Brasileira or TSB), a classification system that identifies economic activities, assets, and project categories that contribute to climate, environmental, and social objectives through specific technical criteria. This system is governed and periodically updated by the Interinstitutional Committee for the TSB (Comitê Interinstitucional da Taxonomia Sustentável Brasileira or CITSB) and is built on principles such as scientific grounding, fair transition, consistency across sectors, technical objectivity, proportionality, and interoperability with foreign taxonomies.

***Policy for Succession of Financial Institutions Managers***

Brazilian financial institutions and other institutions authorized to operate by the Brazilian Central Bank shall implement and maintain internal policies for succession of managers, applicable to higher levels of the institution's management. The internal policy shall encompass the procedures related to recruitment, promotion, appointment and retention of managers in accordance with the institution's rules for identification, evaluation, training and selection of the candidates to management offices.

***Corporate Governance of Financial Institutions***

Financial institutions must (i) remit to the Brazilian Central Bank information on the financial institution's management, controlling group and relevant shareholders, including the obligation to communicate to the regulator any information that may affect the reputation of any such persons; (ii) make available a communication channel allowing employees, contributors, customers, users, associates, or services providers to report anonymously situations indicating illegalities of any nature related to the institution; and (iii) have an internal body responsible for receiving the information and complying with the reporting obligations.

*[**Table of Contents**](#toc)*<br>

***Compliance Policy***

Financial institutions must implement and maintain a compliance policy compatible with the nature, size, complexity, structure, risk profile and business model of the institution, which is intended to ensure an effective compliance risk management by the institution and may be established at the consolidated enterprise level. The compliance policy must establish the scope and purpose of the compliance function in the institution, set forth the organizational structure of the compliance function, specify which personnel is allocated to the compliance function, and establish a segregation of roles among personnel in order to avoid conflicts of interest.

The compliance policy must be approved by the board of directors and the regulation also assigns to the board the responsibility to ensure the following: adequate management of the compliance policy throughout the institution, its effectiveness and continued application, its communication to all employees and services providers, as well as the dissemination of the integrity and ethical standards as part of the institution's culture. The board of directors is also responsible for ensuring the application of measures in case of noncompliance, and for providing the necessary means for the activities related to the compliance functions to be adequately conducted.

***Consumer Protection***

Relationships between consumers and financial institutions are governed by Law No 8,078, dated September 11, 1990, or the "Brazilian Consumer Protection Code," which grants consumers certain rights and sets forth measures to be observed by suppliers, which must be complied with by financial institutions. The Brazilian Consumer Protection Code sets forth as consumer rights, among others, the assistance/facilitation in the defense of consumers' rights, including through reverse burden of proof in their favor, and the possibility of judicial review of contractual provisions deemed abusive.

Furthermore, banking regulation establishes procedures that financial institutions must observe when contracting any transactions, as well as when rendering services. We may highlight the following as examples of said procedures:

&nbsp;&nbsp;&nbsp;&nbsp;• to timely provide the necessary information including rights, duties, responsibilities, costs or advantages,
penalties and possible risks when carrying out a transaction or rendering a service to allow customers and users free choice and decision-making;

&nbsp;&nbsp;&nbsp;&nbsp;• to timely provide, to the customer or user, agreements, receipts, statements, advice and other documents
related to the transactions and services, as well as the possibility of timely cancellation of the agreements;

&nbsp;&nbsp;&nbsp;&nbsp;• formalization of an adequate instrument setting forth the rights and obligations for opening, using
and maintaining a postpaid payment account;

&nbsp;&nbsp;&nbsp;&nbsp;• to forward a payment instrument to the customers' or users' residence or to enable the respective
instrument only upon express request or authorization; and

&nbsp;&nbsp;&nbsp;&nbsp;• identification of end users' beneficiaries for payments or transfer in statements and bills of
the payer, including in situations in which the payment service involves institutions participating in different payment arrangements.

Financial institutions operating exclusively via digital means are excluded from the scope of certain aspects of the regulation.

Law No. 14,181, which amends the Brazilian Consumer Protection Code and Senior Citizens' Statute (Law No. 10,741 of October 1, 2003) to improve provisions related to the offering of consumer credit and provide for the prevention and treatment of over-indebtedness, came into effect on July 2, 2021.

Regarding the prevention of over-indebtedness, such rule created a chapter in the Brazilian Consumer Protection Code dedicated to responsible credit and financial education. The amendments determine the presentation of specific information to the consumer in the granting of credit or installment sales, such as the effective monthly interest rate, late payment interest and the total charges foreseen in the event of late payment.

*[**Table of Contents**](#toc)*<br>

The new law also regulates informational conduct to be observed by the credit supplier regarding the nature and modality of the credit offered, considering the age of the consumer.

The law also included a new chapter in the Brazilian Consumer Protection Code dedicated to the conciliation between debtor and creditor with respect to over-indebtedness. According to the new law, the over-indebted consumer may request the initiation of a debt renegotiation process, with the consumer being responsible for submitting a payment plan proposal, preserving the existential minimum. The unjustified non-attendance of the creditor or his attorney at the conciliation hearing may suspend the payment of the credit, with the interruption of the late payment charges. In the case of a successful conciliation, the court decision that ratifies the agreement will describe the debt payment plan and will be enforceable. A new debt renegotiation request may only be submitted after two years, counting from the settlement of the obligations provided for in the payment plan. In the case of unsuccessful conciliation, the judge, at the consumer's request, will institute proceedings for over-indebtedness to review and integrate the contracts and renegotiate the remaining debts, through a compulsory judicial plan.

On July 27, 2022, the Brazilian federal government adopted Decree No. 11,150/22, or Decree No. 11,150, which seeks to prevent and foster the repayment and settlement of consumer over-indebtedness. The rule grants consumers certain basic rights, including the right to responsible credit practices, financial education and relief from over-indebtedness situations through debt review and renegotiation. To preserve a consumer's "existential minimum," Decree No. 11,150 creates an "existential minimum income" threshold for consumers, which is fixed at R$600.00, or one-quarter of the federal minimum wage that was in effect at the time the decree was adopted. However, the annual adjustment of the minimum wage will not lead to this amount being updated.

Further, on September 30, 2021, the CMN published Resolution No. 4,949. The rule provides the principles and procedures to be adopted in the relationship with customers and users of products and services of financial institutions and other institutions authorized to operate by the Brazilian Central Bank. On October 13, 2021, the Brazilian Central Bank published Resolution No. 155, which establishes almost identical principles and procedures to be adopted by payment institutions and consortium administrators, which are regulated and supervised solely by the Brazilian Central Bank.

CMN Resolution No. 4,949/2021 and Central Bank Resolution No. 155/2021 set forth new rules mainly with the goal of ensuring fair and equitable treatment at all stages of the relationship with institutions providing financial and payments services, as well as a convergence of the interests of such institutions with those of their consumers.

Under CMN Resolution No. 4,949/2021 and Central Bank Resolution No. 155/2021, institutions authorized to operate by the Brazilian Central Bank shall prepare and implement an institutional policy for the relation with consumers and users. Such new policy should consolidate guidelines, strategic objectives and organizational values, so that the conduct of the institution's activities is guided by the principles of ethics, responsibility, transparency and diligence.

CMN Resolution No. 4,949/2021 and Central Bank Resolution No. 155/2021 also provide that institutions authorized to operate by the Brazilian Central Bank and must indicate to such regulatory agency the officer responsible for complying with the obligations provided under the new rules.

The rules also impose other obligations to the regulated entities within their scope, such as the compliance with transparency and suitability rules. CMN Resolution No. 4,949 came into effect on March 1, 2022, and Central Bank Resolution No. 155 came into effect on October 10, 2022.

On October 3, 2023, the President of Brazil enacted Law No. 14,690, which ratifies the emergency program for renegotiation of debts of individuals in default depending on debtor category, which in turn depends on the amount of the debtor's debt (*Desenrola Brasil*). Pursuant to this rule, the CMN and Central Bank issued Resolution No. 5,112 and Resolution No. 365, respectively, establishing other measures to prevent debtor default and consumer over-indebtedness, including rules related to the portability of credit transactions granted in the context of post-paid payment instrument (such as credit cards) financings and rules relating to transparency and disclosure of the total amount of interest and fees charged over post-paid payment instrument financing to consumers, among other matters. Resolution No. 5,112 came into effect on December 26, 2023. However, the provision relating to the limitation on interest rates are applied to financings from January 3, 2024 onward and portability and transparency rules only came into force on July 1, 2024.

Furthermore, on December 26, 2023, the CMN and the Brazilian Central Bank published Joint Resolution No. 8, which requires the institutions authorized to operate by the Brazilian Central Bank to adopt financial literacy measures designed for their clients and natural person users, including individual entrepreneurs, by means of the publication of a financial literacy policy and the provision of financial literacy content and tools in an appropriate language, channel, and timing in order to suit them to the characteristics and needs of clients and users. This rule came into effect on July 1, 2024.

*[**Table of Contents**](#toc)*<br>

On September 17, 2025, the President of Brazil enacted Law No. 15,211, establishing the Digital Children and Adolescents Statute, or "ECA Digital." The implementation of Law No. 15,211 is expected to impose governance, age assurance, parental supervision, transparency, reporting and accountability requirements for companies whose products or services may be accessed by minors, such as applications, online games, social networks, operating systems and digital stores. The rule introduces mandatory risk-prevention and mitigation measures, stricter privacy-by-default settings, limits on data collection, effective age-assurance mechanisms, parental supervision tools, rapid response to illicit or harmful content, and enhanced governance responsibilities for companies, parents, schools and public authorities. The new rule also prohibits exploitative advertising practices, strengthens duties to prevent exposure to inappropriate content and interactions, and mandates technical and organizational controls tailored to risks to minors, creating a new regulatory standard for the online protection of children and adolescents in Brazil. Law No. 15,211/2025 will come into force in March 2026.

***Policy for Relationship with Customers and Users of Financial Products and Services***

Financial institutions and other institutions authorized to operate by the Brazilian Central Bank must have a policy governing the relationship with customers and users of financial products and services. In addition, such entities shall comply with the principles of ethics, liability, transparency and diligence promoting the convergence of interests and the consolidation of the institutional image of credibility, security and expertise.

***Ombudsman***

Financial institutions and other entities that are authorized to operate by the Brazilian Central Bank must have an ombudsman office. An ombudsman office has the following attributes according to the current regulation:

&nbsp;&nbsp;&nbsp;&nbsp;• to provide last resort assistance in connection with customer claims that have not been resolved through
the conventional customer service channels (including the banking correspondents and the customer service assistance channel (*Serviço de Atendimento ao Consumidor*); and

&nbsp;&nbsp;&nbsp;&nbsp;• to act as a communication channel between the financial institutions and their customers, including
for dispute resolution.

Institutions that are part of a financial group are allowed to establish one ombudsman department to service the whole group. The officer in charge of the ombudsman office must prepare a report every six months, which must be provided to the management and auditing bodies. The reports and recordings of interactions of the ombudsman unit with consumers must be available to the Brazilian Central Bank for a period of at least five years.

***Investment Funds Industry Regulation***

Investment funds are subject to the regulation and supervision of the CMN and the CVM and, in certain specific matters, the Brazilian Central Bank. Investment funds may be managed by full-service banks, commercial banks, savings banks, investment banks, credit, financing and investment companies and brokerage and dealer companies within certain operational limits.

Investment funds may invest in any type of financial instrument available in the financial and capital markets, including, for example, fixed income instruments, stocks, debentures and derivative products, provided that, in addition to the denomination of the fund, a reference to the relevant type of fund is included.

On July 24, 2025, the CMN issued Resolution No. 5,237, which consolidates and modernizes the regulatory framework applicable to SCFIs. The rule consolidated previously disparate principles across multiple and outdated normative acts, and also revoked outdated rules. Key regulatory implications include the requirement for SCFIs to operate as joint-stock companies, maintain a minimum paid-in capital and net equity of R$7 million (with a 30% reduction for those headquartered outside Rio de Janeiro or São Paulo), and restrict their activities to a defined set of financial operations.

***Broker-Dealer Regulation***

Broker and dealer firms are part of the national financial system and are subject to CMN, Brazilian Central Bank and CVM regulation and supervision. Brokerage firms must be chartered by the Brazilian Central Bank and authorized to trade on stock exchanges. Both brokers and dealers may act as underwriters in the public placement of securities and engage in the brokerage of foreign currency in any exchange market.

*[**Table of Contents**](#toc)*<br>

Since August 29, 2019, securities brokers and dealers may loan their own securities to their customers as long as they use the funds as collateral for operations in which the institution itself intermediates. The loan transaction consists of the transfer of assets from the institution: (i) to the customer, in conjunction with the transfer of that asset to the clearinghouse or clearing and settlement service provider; or (ii) to the clearinghouse or clearing and settlement service provider on behalf of the customer through powers established in a formal written power of attorney. In either case, the assets or set of assets in question shall return to the positions originally held at the end of the period stipulated in the contract. To offer this new service, securities brokers and dealers must appoint a director responsible for the loan operations under consideration.

Since November 27, 2020, securities brokers and dealers may issue electronic currency and maintain payment accounts.

***Virtual Assets and Virtual Asset Service Providers***

In Brazil, the virtual asset market is governed by Law No. 14,478/2022, which set the guidelines for the provision of virtual asset services and for the regulation of virtual asset service providers, or "VASPs." Under Decree No. 11,563/2023, the Brazilian Central Bank is responsible for authorizing, regulating and supervising the entities qualifying as VASPs under Law No. 14,478/2022 – which excludes virtual assets qualifying as securities (among others).

On November 10, 2025, the Brazilian Central Bank issued Resolutions Nos. 519, 520 and 521, respectively regulating the licensing process applicable to VASPs, the general rules related to the organization and operations of VASPs, and the foreign exchange registrations related to cross-border virtual assets transactions.

Pursuant to Brazilian Central Bank Resolution No. 520, VASPs must operate under one of three regulated modalities, each defined by the scope of services performed on behalf of clients: (i) intermediary of virtual assets; (ii) custodian of virtual assets; and (iii) exchange (i.e., combining both intermediation and custody). Resolution No. 520 classifies VASPs by modality and restricts cross-activity combinations, except where expressly authorized, thereby structuring the market by function and corresponding controls, governance, and client-facing obligations.

Under Brazilian Central Bank Resolution No. 520, an intermediary of virtual assets, has as its corporate purpose the intermediation of virtual assets and may, solely on behalf of third parties, subscribe issuances, buy, sell and exchange virtual assets, administer portfolios comprising virtual assets and financial instruments, act as fiduciary agent in virtual asset market operations, perform staking operations, and conduct foreign exchange-related virtual asset services, among other activities authorized by the Brazilian Central Bank. Intermediaries may also, with prior notice or authorization where applicable, act as e-money issuers, liquidity providers, market makers, or providers of financial services such as issuer advisory and independent financial counseling, subject to applicable Brazilian Central Bank and CVM rules and any specific foreign exchange regulations for activities related to foreign exchange, or FX.

On the other hand, a custodian of virtual assets has as its corporate purpose the custody of virtual assets and is responsible for safeguarding and controlling instruments that confer control over virtual assets (such as private keys); maintaining accurate, timely position records and reconciliations; carrying out client instructions; handling events affecting the assets; and administering data and information necessary to exercise rights. Only custodians authorized to perform the full set of core custody functions may offer staking for clients, and any technology service engaged by a custodian must not enable the technology provider to interfere with core custody activities or clients' exercise of rights. Such arrangements are deemed relevant outsourcing and are subject to prudential outsourcing and cloud rules applicable to BCB-supervised institutions. An exchange (corretora de ativos virtuais), in its turn, combines, as its corporate purpose, both intermediation and custody of virtual assets, effectively operating as an integrated broker-custodian platform under a single license. By contrast, standalone intermediaries and standalone custodians are prohibited from combining activities of other modalities, which prevents unlicensed commingling of functions and reinforces the separation of roles unless the entity is formally licensed as an exchange.

Across modalities, Brazilian Central Bank Resolution No. 520 sets forth baseline operational and prudential requirements, including: segregation of client funds and assets from the VASP's own; prohibitions on using client assets for proprietary transactions (with narrow, disclosure-based exceptions, such as staking under specific safeguards or express consent from qualified/professional investors); robust governance, risk management, cybersecurity, and AML/CFT frameworks; conflict-mitigation and transparency obligations; and enhanced disclosures regarding services, risks, safeguards, and the absence of deposit-insurance coverage for virtual assets. These safeguards are designed to protect client rights, ensure orderly operations, and harmonize VASPs with standards applicable to BCB-supervised financial institutions.

Resolution No. 520 also clarifies that, in addition to licensed VASPs, the following Brazilian Central Bank-authorized institutions may provide virtual assets intermediation and custody services: commercial, foreign exchange, investment and multi-purpose banks (such as us), Caixa Econômica Federal, securities brokerage and dealership firms, and foreign-exchange brokers (limited to intermediation). These activities are subject to eligibility, prior formal communication to the Brazilian Central Bank (with a 90-day stand-still for new entrants) and supervisory conditions, including independent technical certification where applicable.

*[**Table of Contents**](#toc)*<br>

Resolution No. 519 establishes the authorization processes applicable to VASPs and certain broker-dealers, setting minimum requirements for authorization, including controlling shareholders' financial capacity and lawful capital, business viability, IT and governance adequacy, and fit-and-proper and technical capacity of controlling shareholders and managers. Transactions subject to prior Brazilian Central Bank approval include: authorization to operate, changes in VASP modality, transfers of control and reorganizations (merger, spin-off, incorporation), corporate transformations, appointments to management positions, and capital and corporate purpose changes. For VASPs already active prior to February 2, 2026, the licensing runs in two phases: phase 1 (evidence of activity; assessment of controllers/qualified holders and basic prudential conditions) and phase 2 (full compliance with remaining requirements). If an application is denied or archived with final effect, incumbents must cease operations and arrange the orderly return of clients' virtual assets and funds.

Resolution No. 521 integrates specific virtual-asset services into the FX framework, listing activities such as international payments or transfers with virtual assets, transfers to/from self-hosted wallets, and buy/sell or swaps of fiat-referenced virtual assets. It imposes operational limits and conditions, including maximum values when the counterparty is not an FX-authorized institution (e.g., US$100,000 for VASPs and US$500,000 for certain brokers/banks), a prohibition on buying/selling virtual assets with payment in foreign currency, and enhanced data and monthly reporting duties, including purpose codes, counterpart data, and self-custody wallet identification. It also provides a transitional rule allowing incumbents to continue FX-related virtual asset services while they apply for authorization, which must include a request to operate in the FX market.

These rules will come into force on February 2, 2026. VASPs already operating as of that date benefit from a transitional "grandfathering" regime. Such entities must submit a licensing application to the Brazilian Central Bank within 270 days from February 2, 2026, and evidence compliance with core risk, cybersecurity, AML/CFT, sanctions, and accounting/audit requirements. If a timely application is filed, the VASP may continue providing its existing services during the authorization process, but it may not assume a different modality until the process concludes. Entities that fail to apply on time must cease operations within 30 days after the deadline. These transitional provisions align legacy operators with the new framework while avoiding market disruption during the authorization period.

***Foreign Exchange Market***

Transactions involving the sale and purchase of foreign currency in Brazil may be conducted only by institutions duly authorized by the Brazilian Central Bank to operate in the foreign exchange market. There is no current limit to long or short positions in foreign currency for banks authorized to carry out transactions on the foreign exchange market. Other institutions within the national financial system are not allowed to have short positions in foreign currency, although there are no limits with respect to foreign exchange long positions.

The Brazilian Central Bank imposes a limit on the total exposure in foreign currency transactions and transactions subject to foreign exchange fluctuation undertaken by Brazilian financial institutions, including branches abroad, and their direct and indirect affiliates. The limit is currently equivalent to 30.0% of the financial institution's regulatory capital (*patrimônio de referência*), on a consolidated basis. The CMN, the Brazilian Central Bank and the Brazilian government may change the regulation applicable to foreign currency and foreign exchange transactions undertaken by Brazilian financial institutions in accordance with Brazil's economic policy (including its foreign exchange policy).

On December 20, 2021, the President of Brazil sanctioned Law No. 14,286, approved by the Brazilian Senate on December 8, 2021, or the "New Foreign Exchange Law." The New Foreign Exchange Law, an initiative of the Brazilian Central Bank, overhauls the rules applicable to the Brazilian foreign exchange market and contains provisions regarding Brazilian capital abroad and foreign capital within Brazil. The initiative aims to modernize, simplify and reduce legal doubts associated with current Brazilian foreign exchange legislation.

The main aspects of the New Foreign Exchange Law are: (i) ratification, at the legal level, that foreign exchange transactions may be carried out freely (provided such transactions are carried out by entities authorized to operate in this market and subject to applicable rules); (ii) granting of broad powers to the CMN and the Brazilian Central Bank to regulate the foreign exchange market and foreign exchange operations; (iii) expansion of international correspondence activities by Brazilian banks; (iv) possibility of Brazilian financial institutions investing and lending abroad funds that have been raised in Brazil or abroad; (v) the exclusion from its scope of foreign currency purchase and sale operations of up to U.S.$500 carried out between individuals on an occasional and non-professional basis; and (vi) the granting of powers to the monetary authorities to establish situations in which the prohibition of the private offset of credits between residents and nonresidents, as well as payments in foreign currency in Brazil, would not apply.

*[**Table of Contents**](#toc)*<br>

Law No. 14,286 came into effect on December 30, 2022.

In 2022, the CMN and the Brazilian Central Bank established new guidelines for transactions performed in the foreign exchange market, through the issuance of Resolutions Nos. 277 and 280, of December 31, 2022.

Such rules aim to regulate the New Foreign Exchange Law in respect to the inflow and outflow of Brazilian currency and foreign currency to and from Brazil, repealing and replacing several rules that previously regulated the topic, including Circulars Nos. 3,691 and 3,690 of December 16, 2013. The main changes brought forth by Resolution No. 277 include: (i) enabling authorized institutions, such as us, to carry out foreign exchange transactions in a free format while observing the guidelines established by the Brazilian Central Bank (as opposed to the former rules, which required that authorized institutions execute a standard agreement with clients); (ii) enabling authorized institutions to use their own criteria to request or waive supporting documentation prior to the execution of a foreign exchange transaction, considering the client's internal risk profile within the institution and the characteristics of the transaction; and (iii) simplifying the process for the classification of foreign exchange transactions, considering that the New Foreign Exchange Law establishes that the purpose shall be made clear by the client (as opposed to the former rules, whereby the classification of the purpose of the transactions was the responsibility of the authorized institutions, which were liable for any inaccuracy). Likewise, Resolution No. 280 establishes the definitions of "resident" and "non-resident" to be applied to individuals and legal entities, which are now materially equivalent to that of a domestic current or payment account.

On December 3, 2024, the Brazilian Central Bank and the CVM issued Joint Resolution No. 13, which establishes a new regulatory framework for foreign investors in the financial and securities markets. The new rule aims to simplify and modernize procedures for non-resident operations in Brazil, enhancing efficiency and aligning with international best practices. The new regulation replaces previous resolutions, including CMN Resolution No. 4,373, of September 29, 2014. The Joint Resolution's main changes include equalizing minimum registration requirements for resident and non-resident investors, eliminating the need for non-resident individual investors to appoint a representative in Brazil or register with the CVM for certain operations, and expanding the use of non-resident checking or payment accounts for financial investments. Additionally, it removes the requirement for mandatory simultaneous foreign exchange operations for investment conversions and the need to register such investments in the RDE-Portfolio system. These measures aim to provide greater clarity and security for investors, particularly regarding changes in residency. Joint Resolution No. 13 came into effect on January 1, 2025.

***Foreign Investment in Brazilian Financial Institutions***

According to the Brazilian federal constitution, the acquisition of equity interests by foreign individuals or legal entities in the capital stock of Brazilian financial institutions is forbidden, unless permitted by bilateral international treaties or by the Brazilian government by means of a presidential decree. A presidential decree issued on November 13, 1997, issued in respect of Banco Meridional do Brasil S.A. (our legal predecessor) allows 100% foreign participation in our capital stock. Foreign investors may acquire the shares issued by Santander Brasil as a result of this decree. In addition, foreign investors may acquire publicly traded nonvoting shares of Brazilian financial institutions traded on a stock exchange or securities depositary receipts offered abroad representing shares without specific authorization.

Following the enactment of Decree No. 10,029, the Brazilian Central Bank published, on January 22, 2020, Circular No. 3,977 recognizing as an interest of the Brazilian government the foreign holding of equity or increase in equity interest of financial institutions headquartered in Brazil (which is still subject to the same requirements and procedures applicable to the acquisition of equity in any Brazilian financial institution), as well as the opening of local branches of foreign financial institutions. However, since Santander Brasil had already been granted a specific presidential decree authorizing the foreign interest in its share capital, prior to Decree No. 10,029/19 being issued it does not affect its operations in Brazil.

A foreign financial institution duly authorized to operate in Brazil through a branch or a subsidiary is subject to the same rules, regulations and requirements that are applicable to any Brazilian financial institution.

***Bank Correspondents***

Financial institutions are allowed to provide specific services to customers, including customer services, through other entities. These entities are called "bank correspondents" and the relationship between the financial institution and the bank correspondent is ruled by a specific regulation published by CMN and is subject to the supervision of the Brazilian Central Bank.

*[**Table of Contents**](#toc)*<br>

On July 29, 2021, the CMN published Resolution No. 4,935, which revoked CMN Resolution No. 3,954, of February 24, 2011, changing the regulation of banking correspondents in Brazil. Banking correspondents are companies contracted by financial institutions and other institutions authorized to operate by the Brazilian Central Bank to provide services to their contracting institutions.

The new rule determines that these institutions set forth a policy for the operation and hiring of their correspondents, and it should be formalized by a specific document and approved by the institution's board of officers or board of directors. This operation and contracting policy should provide for the criteria required for contracting correspondents, internal controls related to the correspondent and remuneration rules for the provision of services.

The contracting institutions will continue to be required to maintain adequate internal control systems in order to monitor the public service activities carried out by the contracted correspondents and the contracting institution's internal audit must annually assess the effectiveness of these quality control mechanisms.

In addition, with the inclusion of the express possibility of the correspondents acting in a digital setting, some provisions were improved, highlighting the need for the correspondent's digital platform itself to have a minimum technical qualification that allows the offering of products and services suited to the needs, interests and goals of the contracting institution's customers.

CMN Resolution No. 4,935 came into effect on February 1, 2022.

***Regulation of Branches***

Authorization by the Brazilian Central Bank is required for operations of branches or subsidiaries of Brazilian financial institutions, upon the compliance with certain term, capital and equity requirements, as well as the submission of an economic and financial feasibility analysis.

The Brazilian Central Bank's prior authorization is also required in order to: (i) allocate new funds to branches or subsidiaries abroad; (ii) subscribe capital increases, directly or indirectly, in subsidiaries abroad; (iii) increase equity participation, directly or indirectly, in subsidiaries abroad; and/or (iv) merge or spin off, directly or indirectly, subsidiaries abroad.

The Brazilian Central Bank determines that financial institutions can install the following establishments in Brazil: (i) branches, (ii) teller booths, (iii) automatic teller machines, and (iv) segregated administrative units, provided that, for items (i) to (iii), conformity with requirements of minimum capital and operating limits are necessary.

On January 3, 2023, the Brazilian Central Bank published Normative Ruling No. 342, which amended Normative Ruling No. 299/22 and provides procedures, documents, terms and necessary information for requests related to the participation of financial institutions, such as us, on other companies' corporate capital; and establishment of branches abroad. This new rule came into force on its publication date.

***Cayman Islands Banking Regulation***

We have a branch in the Cayman Islands with its own staff and representative officers, Banco Santander (Brasil) S.A. – Grand Cayman Branch is licensed under The Banks and Trust Companies Law (2013 Revision) of the Cayman Islands, or the "Banks and Trust Companies Law," as a Category "B" Bank and it is duly registered as a Foreign Company with the Registrar of Companies in the Cayman Islands. The branch, therefore, is duly authorized to carry on banking business in the Cayman Islands. The branch was authorized by the local authorities to act as its own registered office and it is located at the Waterfront Centre Building, 28, North Church Street – 2nd floor, George Town, Grand Cayman, Cayman Islands, P.O. Box 10444 – KYI-1004, Phone: 1-345-769-4401 and Fax: <u>1-345-769-4601</u>.

Our Grand Cayman Branch is currently engaged in the business of sourcing funds in the international banking and capital markets to provide credit lines for us, which are then extended to our customers for working capital and trade-related financings. It also takes deposits in foreign currency from corporate and individual customers and extends credit to Brazilian and non-Brazilian customers, mainly to support trade transactions with Brazil. The results of the operations of the Grand Cayman Branch are consolidated in our consolidated financial statements.

Banks and trust companies wishing to conduct business from within the Cayman Islands must be licensed by the Cayman Islands Monetary Authority under the Banks and Trust Companies Law, irrespective of whether the business is to be actually conducted in the Cayman Islands.

*[**Table of Contents**](#toc)*<br>

Under the Banks and Trust Companies Law, there are two main categories of banking license: a category "A" license, which permits unrestricted domestic and offshore banking business, and a category "B" license, which permits principally offshore banking business. The holder of a category "B" license may have an office in the Cayman Islands and conduct business with other licensees and offshore companies but, except in limited circumstances, may not do banking business locally with the public or residents of the Cayman Islands. We have an unrestricted category "B" license.

There are no specific ratio or liquidity requirements under the Banks and Trust Companies Law, but the Cayman Islands Monetary Authority will expect observance of prudent banking practices, and the Banks and Trust Companies Law imposes a minimum net worth requirement of an amount equal to CI$400,000 (or, in the case of licensees holding a restricted category "B" or a restricted trust license, CI$20,000). As of December 31, 2025, CI$1 was equivalent to R$6.5890 according to the Brazilian Central Bank.

***Luxembourg Banking Regulation***

Branches of credit institutions from outside the European Union ("non-EU credit institutions") must be licensed by the Luxembourg Minister of Finance under the law of April 5, 1993 on the financial sector, as amended, in order to operate in Luxembourg.

We have a branch in Luxembourg with its own staff and representative officers. Our Luxembourg branch is licensed as a Luxembourg branch of a non-EU credit institution and is duly registered with the Luxembourg Trade and Companies' Registry. The branch, therefore, is duly authorized to carry on banking business in Luxembourg. Its registered offices are at 35F, Avenue J. F. Kennedy, 2nd floor, L-1855 Luxembourg, Grand Duchy of Luxembourg.

Our Luxembourg branch is currently engaged in the business of sourcing funds in the international banking and capital markets to provide credit lines for us, which are then extended to our customers for working capital and trade-related financings. It also takes deposits in foreign currency from corporate and individual customers and extends credit to Brazilian and non-Brazilian customers, mainly to support trade transactions involving Brazil. The results of the operations of the Luxembourg branch are consolidated in our consolidated financial statements.

Luxembourg law requires the Luxembourg branch to have a minimum endowment capital of €8,700,000 and the solvency, and liquidity requirements deriving, among others, from EU Regulation No 575/2013 of the European Parliament and of the Council of June 26, 2013 on prudential requirements for credit institutions and investment firms apply to it.

***U.S. Financial Regulatory Reform***

Santander Brasil is a subsidiary of Santander Spain, a foreign banking organization, or "FBO," with operations in the United States. As a subsidiary of Santander Spain, Santander Brasil is subject to certain U.S. financial regulatory laws and rules. In addition to regulations, the U.S. financial regulatory agencies may issue policy statements, interpretive letters and similar written guidance.

Financial regulatory statutes and rules are continually under review by the U.S. Congress and U.S. financial regulatory agencies. Changes in key personnel at the U.S. financial regulatory agencies may result in differing interpretations of existing rules and guidelines and potentially more stringent enforcement and more severe penalties than previously. The full spectrum of risks that result from pending or future U.S. financial services legislation or regulations cannot be fully known; however, such risks could be material and we could be materially and adversely affected by them.

*Volcker Rule*

Owing to its status as a subsidiary of an FBO, Santander Brasil is subject to Section 13 of the U.S. Bank Holding Company Act and its implementing rules (collectively, the "Volcker Rule"). The Volcker Rule prohibits "banking entities" from engaging in certain forms of proprietary trading or from sponsoring or investing in "covered funds," in each case subject to certain exceptions. The Volcker Rule also limits the ability of banking entities and their affiliates to enter into certain transactions with covered funds with which they or their affiliates have certain relationships. The Group has adopted processes to establish, maintain, enforce, review and test the compliance program designed to achieve and maintain compliance with the Volcker Rule. The Volcker Rule contains exclusions and certain exemptions for, among others, market-making, hedging, underwriting, trading in U.S. government and agency obligations and certain foreign government obligations, and trading solely outside the United States, and also permits certain ownership interests in certain types of funds to be retained. Santander Spain's non-U.S. banking organization subsidiaries, including Santander Brasil, are largely able to continue their activities outside the United States in reliance on the "solely outside the U.S." exemptions from the Volcker Rule. Those exemptions generally exempt proprietary trading, and sponsoring or investing in covered funds if, among other restrictions, the essential actions take place outside the United States.

*[**Table of Contents**](#toc)*<br>

Santander Spain will continue to monitor Volcker Rule-related developments and assess their impact on its operations, including those of Santander Brasil, as necessary.

*Other U.S. Financial Regulations*

Santander Spain is subject to other U.S. financial regulatory regimes that do not directly apply to Santander Brasil based on the current scope of its operations. For example, Santander Spain, as a Category IV FBO, and Santander Holdings USA, Santander Spain's U.S. intermediate holding company, or "IHC," as a Category IV IHC, are subject to enhanced prudential standards imposed by the Board of Governors of the Federal Reserve System, or the "Federal Reserve Board," on large banking organizations that exceed certain asset thresholds. Enhanced prudential standards include risk-based and leverage capital requirements, liquidity requirements, risk management and governance requirements, capital planning and stress testing requirements, resolution planning requirements, and risk management requirements. Category IV institutions are subject to the least exacting level of enhanced prudential standards.

In addition, Santander Spain is registered as a non-US swap dealer with the CFTC and is registered as a non-US security-based swap dealer with the SEC. As such, Santander Spain is subject to certain clearing, exchange trading, uncleared swap margin, business conduct, reporting and other requirements.

***Foreign Corrupt Practices Act Regulations***

Santander Brasil, as a foreign private issuer whose securities are registered under the Exchange Act, is subject to the U.S. Foreign Corrupt Practices Act, or the "FCPA." The FCPA generally prohibits such issuers and their directors, officers, employees and agents from using any means or instrumentality of U.S. interstate commerce in furtherance of any offer or payment of money to any foreign official or political party for the purpose of influencing a decision of such person in order to obtain or retain business. It also requires that the issuer maintain books and records and a system of internal accounting controls sufficient to provide reasonable assurance that accountability of assets is maintained and accurate financial statements can be prepared. Penalties, fines and imprisonment of Santander Brasil's officers and/or directors can be imposed for violations of the FCPA.

***U.S. Sanctions***

"Sanction(s)" means any international economic sanction administered or enforced by the United States government (including without limitation, the Office of Foreign Assets Control, or "OFAC"), the UN Security Council, the European Union or His Majesty's Treasury. OFAC is responsible for administering economic sanctions imposed against designated foreign countries, governments, individuals and entities pursuant to various Executive Orders, statutes and regulations.

OFAC-administered sanctions take many different forms. For example, sanctions may include: (1) restrictions on U.S. persons' trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on U.S. persons engaging in financial transactions relating to, making investments in, or providing investment-related advice or assistance to, a sanctioned country; and (2) blocking of assets of targeted governments or "specially designated nationals," by prohibiting transfers of property subject to U.S. jurisdiction, including property in the possession or control of U.S. persons. Blocked assets, such as property and bank deposits, cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. In addition, non-U.S. persons can be liable for "causing" a sanctions violation by a U.S. person or can violate U.S. sanctions by exporting services from the United States to a sanctions target, for example by engaging in transactions with targets of U.S. sanctions denominated in U.S. dollars that clear through U.S. financial institutions (including through U.S. branches or subsidiaries of non-U.S. banks).

Failure to comply with applicable U.S. sanctions could have serious legal and reputational consequences, including significant civil monetary penalties and, in the most severe cases, criminal penalties.

In addition, the U.S. government has imposed various sanctions that prevent non-U.S. persons, including non-U.S. financial institutions from engaging in certain activities undertaken outside the United States and without the involvement of any U.S. persons ("secondary sanctions"). If a non-U.S. financial institution were determined to have engaged in activities targeted by certain U.S. secondary sanctions or used proceeds produced by such activities targeted, it could lose its ability to open or maintain correspondent or payable-through accounts with U.S. financial institutions, among other potential consequences.

***Antitrust Regulation***

According to the Brazilian antitrust law, actions that concentrate market share must be previously submitted to CADE for approval if the following criteria are met: (i) at least one of the groups involved in the deal has posted annual gross revenues or volume of business equal to or over R$750 million, in Brazil, in the year prior to the transaction; and (ii) at least another group has posted annual gross revenues or volume of business equal to or over R$75 million, in Brazil, in the year prior to the transaction. Closing of a transaction without CADE's approval will subject the parties to fines ranging from R$60,000 to R$60 million.

The Brazilian Central Bank will also examine certain corporate reorganizations and other acts involving two or more financial institutions not only considering their potential effects on the financial system and its stability but also any potential impacts regarding market concentration and competition. Upon approval of the transaction, the Brazilian Central Bank may establish certain restrictions and require that the financial institutions execute an agreement of market concentration control, pursuant to which the terms and conditions of the sharing of the efficiency gain resulting from the act shall be set forth.

In December 2018, the Brazilian Central Bank and CADE approved a joint normative act establishing procedures with the purpose of increasing efficiency for their respective actions regarding antitrust matters. Pursuant to the joint normative act, the authorities are authorized to share information for the purposes of their respective activities and carry out meetings with each other to discuss matters requiring the regulatory cooperation between both authorities.

***Insolvency Laws Concerning Financial Institutions***

Financial institutions are subject to the proceedings established by Law No. 6,024 of March 13, 1974, or "Law No. 6,024," which establishes the applicable provisions in the event of intervention or extrajudicial liquidation by the Brazilian Central Bank, as well as to bankruptcy proceedings.

Intervention and extrajudicial liquidation occur when the Brazilian Central Bank has determined that the financial institution is in bad financial condition or upon the occurrence of events that may impact the creditors' situation. Such measures are imposed by the Brazilian Central Bank in order to avoid the bankruptcy of the entity.

***Intervention***

An intervention can be carried out at the discretion of the Brazilian Central Bank in the following cases:

&nbsp;&nbsp;&nbsp;&nbsp;• risk to the creditors due to mismanagement;

&nbsp;&nbsp;&nbsp;&nbsp;• consistent violation of Brazilian banking laws or regulations; or

&nbsp;&nbsp;&nbsp;&nbsp;• if the intervention is a feasible alternative to the liquidation of the financial institution.

As of the date on which it is ordered, the intervention will automatically suspend the enforceability of the payable obligations; prevent early termination or maturity of any previously contracted obligations; and freeze deposits existing on the date on which the intervention is decreed.

The intervention will cease if interested parties undertake to continue the economic activities of the financial institution, by presenting the necessary guarantees, as determined by the Brazilian Central Bank, when the situation of the entity is regularized as determined by the Brazilian Central Bank; or when extrajudicial liquidation or bankruptcy of the entity is ordered.

Intervention may also be ordered upon the request of a financial institution's management.

***Extrajudicial Liquidation***

Extrajudicial liquidation is an administrative proceeding decreed by the Brazilian Central Bank (except that it is not applicable to financial institutions controlled by the Brazilian federal government) and conducted by a liquidator appointed by the Brazilian Central Bank. This extraordinary measure aims at terminating the activities of the affected financial institution, liquidating its assets and paying its liabilities, as in a judicially decreed bankruptcy. The Brazilian Central Bank will place a financial institution in extrajudicial liquidation if:

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• the institution's economic or financial situation is at risk, particularly when the institution
ceases to meet its obligations as they become due, or upon the occurrence of an event that could indicate a state of insolvency under
the rules of the Bankruptcy Law;

&nbsp;&nbsp;&nbsp;&nbsp;• management seriously violates Brazilian banking laws, regulations or rulings;

&nbsp;&nbsp;&nbsp;&nbsp;• the institution suffers a loss which subjects its unprivileged and unsecured creditors to severe risk;
and/or

&nbsp;&nbsp;&nbsp;&nbsp;• upon revocation of the authorization to operate, the institution does not initiate ordinary liquidation
proceedings within 90 days or, if initiated, the Brazilian Central Bank determines that the pace of the liquidation may harm the institution's
creditors.

A request for liquidation procedures can also be filed on reasonable grounds by the officers of the respective financial institution or by the receiver appointed by the Brazilian Central Bank in the receivership procedure.

The decree of extrajudicial liquidation will: (i) suspend the actions or foreclose on rights and interests relating to the estate of the entity being liquidated, while no other actions or executions may be brought during the liquidation; (ii) accelerate the obligations of the entity; and (iii) interrupt the statute of limitations with regard to the obligations assumed by the institution.

Extrajudicial liquidation procedures may be terminated:

&nbsp;&nbsp;&nbsp;&nbsp;• by discretionary decision of the Brazilian Central Bank if the parties involved undertake the administration
of the financial institution after having provided the necessary guarantees; or

&nbsp;&nbsp;&nbsp;&nbsp;• when the final accounts of the receiver are delivered and approved and subsequently registered in the
relevant public records;

&nbsp;&nbsp;&nbsp;&nbsp;• when converted into ordinary liquidation; or

&nbsp;&nbsp;&nbsp;&nbsp;• when a financial institution is declared bankrupt.

***Temporary Special Administration Regime (Regime de Administração Especial Temporária or "RAET")***

In addition to the intervention procedures described above, the Brazilian Central Bank may also establish a RAET, under Law 9,447, dated March 14, 1997 combined with Law No. 6,024/74, which is a less severe form of the Brazilian Central Bank intervention in private and nonfederal public financial institutions that allows institutions to continue to operate normally. The RAET may be ordered in the case of an institution that:

&nbsp;&nbsp;&nbsp;&nbsp;• continually enters into recurrent operations that are against economic or financial policies set forth
in federal law;

&nbsp;&nbsp;&nbsp;&nbsp;• faces a shortage of assets;

&nbsp;&nbsp;&nbsp;&nbsp;• fails to comply with the compulsory reserves rules;

&nbsp;&nbsp;&nbsp;&nbsp;• reveals the existence of hidden liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;• experiences the occurrence of situations that cause receivership pursuant to current legislation;

&nbsp;&nbsp;&nbsp;&nbsp;• has reckless or fraudulent management; or

&nbsp;&nbsp;&nbsp;&nbsp;• carries out activities which call for an intervention.

The main objective of a RAET is to assist the recovery of the financial condition of the institution under special administration and thereby avoid intervention and/or liquidation. Therefore, a RAET does not affect the day-to-day business, operations, liabilities or rights of the financial institution, which continues to operate in the ordinary course of business. Measures which may be adopted by the institution include the transfer of assets, rights and obligations to other entities, and corporate restructuring of these entities, with a view to the continuity of the institution's business or activities.

There is no minimum term for a RAET, which ceases upon the occurrence of any of the following events: (i) acquisition by the Brazilian federal government of control of the financial institution, (ii) corporate restructuring, merger, spinoff, amalgamation or transfer of the controlling interest of the financial institution, (iii) decision by the Brazilian Central Bank, or (iv) declaration of extrajudicial liquidation of the financial institution.

*[**Table of Contents**](#toc)*<br>

***Bankruptcy Law***

Law No. 11,101, of February 9, 2005, as amended, or the "Bankruptcy Law," regulates judicial reorganizations, out-of-court reorganizations and the bankruptcy of individuals and corporations that have occurred since 2005 and applies to financial institutions only with respect to the matters not specifically regulated by the intervention and extrajudicial liquidation regimes described above.

On December 24, 2020, Law No. 14,112, or "Law No. 14,112/20," was passed. Law No. 14,112/20 overhauls the current Bankruptcy Law in several material aspects. Law No. 14,112/20 came into effect on January 23, 2021. Certain changes arising from this new legislation may affect enforcement and priority matters, such as: (i) the possibility of creditors putting forward an alternative judicial reorganization plan; (ii) new rules on the approval of post-petition loans in judicial reorganization and on priority claims in case of conversion to bankruptcy liquidation; (iii) more flexible quorum and mechanics in the extrajudicial reorganization process; (iv) new rules to expedite the bankruptcy liquidation process; (v) new methods for restructuring of the debtor's tax liabilities and installment payments, as well as new taxation schemes; and (vi) incorporation of rules on cross-border insolvency proceedings into the Brazilian framework.

Law No. 14,112/20 replicates, with some adjustments, the provisions of the UNCITRAL Model Law on Cross-Border Insolvency. As a result, Law No. 14,112/20 sets out some rules on access of foreign representatives to courts in Brazil, the method and requirements for recognition of foreign main and ancillary proceedings, authorization for the debtor and his representatives to act in other countries, methods of communication and cooperation between foreign authorities and representatives and the Brazilian jurisdiction, and the processing of concurrent proceedings.

Law No. 14,112/20 also sets forth, among other measures, (i) a protection for creditors that agree on the conversion of debt into equity against potential transfer of liability with regard to the debtor's obligations; (ii) the stay period and constraints on the assets of the debtor under judicial reorganization; (iii) conciliation and mediation measures before and during judicial reorganization proceedings; and (iv) the rules on procedural and substantive consolidation. Law No. 14,112/20 also sets out that a bankruptcy decree does not reach beyond the bankrupt itself, save when the disregard doctrine is to apply.

***Repayment of Creditors in a Liquidation or Bankruptcy***

In the event of extrajudicial liquidation or bankruptcy of a financial institution, creditors are paid pursuant to their priorities and privileges. Prepetition claims are paid on a ratable basis in the following order: labor credits; secured credits; tax credits; credits with special privileges; credits with general privileges; unsecured credits; contractual fines and pecuniary penalties for breach of administrative or criminal laws, including those of a tax nature; and subordinated credits.

The current law confers immunity from attachment of compulsory deposits maintained by financial institutions with the Brazilian Central Bank. Such deposits may not be attached in actions by a bank's general creditors for the repayment of debts and require that the assets of any insolvent bank funded by loans made by foreign banks under trade finance lines be used to repay amounts owing under such lines in preference to those amounts owing to the general creditors of such insolvent bank.

***Recovery Plans for Systematically Important Financial Institutions***

Systemically important Brazilian financial institutions must implement a recovery plan (*plano de recuperação*), with the aim of reestablishing adequate levels of capital and liquidity and to preserve the viability of such institutions. The recovery plans must identify their critical functions for the National Financial System, adopt stress-testing scenarios, define clear and transparent governance procedures, assess possible barriers to the entity's recovery, as well as implement effective communication plans with key stakeholders.

***Deposit Insurance – FGC***

The purpose of the FGC is to guarantee the payment of funds deposited with financial institutions in case of intervention, liquidation, bankruptcy or insolvency. The FGC is funded by ordinary contributions made by the financial institutions in the amount of 0.01% of the total amount of outstanding balances of the accounts corresponding to guaranteed obligations, and certain special contributions as determined. Delay in performing such contributions is subject to a penalty of 2% over the amount of the contribution.

*[**Table of Contents**](#toc)*<br>

The total amount of credit in the form of demand deposits, savings deposits, time deposits, deposits maintained in accounts blocked for transactions with checks (for the registration and control of funds relating to the rendering of services of payment of salaries, earnings, pensions), bills of exchange, real estate bills, mortgage bills, real estate credit bills and repurchase and resale agreements whose objects are instruments issued after March 8, 2012 by a company of the same group due to each customer by a financial institution (or by financial institutions of the same financial group) will be guaranteed by the FGC for up to a maximum of R$250,000 per customer. The FGC targets maintaining liquidity at 2.5% (with a band between 2.3% and 2.7%) of covered balances, and reductions in contributions may be proposed when the FGC's liquidity is at or above the target and the Resolution Fund meets its target, subject to CMN authorization. Under the current rules, the ordinary guarantee does not cover, among others, deposits, loans or funds raised abroad; deposits captured from residents abroad; judicial deposits; any subordinated instruments; or credits held by financial institutions and other institutions authorized by the Brazilian Central Bank, complementary pension entities (including RPPS), insurance companies, capitalization companies, investment clubs and investment funds, and institutional investors resident or domiciled abroad. Since December 2017, a limit of R$1,000,000 per four-year period applies to the aggregate coverage of a creditor's credits against all associated institutions, applicable to operations contracted or repactuated from December 22, 2017.

Additionally, CMN Resolution No. 5,238, of August 1, 2025, introduced new amendments to the FGC framework to: (i) introduce an additional monthly contribution whenever the Reference Value exceeds four times the Adjusted Net Equity and 60% of the institution's Reference Funding; (ii) require associated institutions to allocate amounts exclusively in federal government securities when the Reference Value exceeds six times the Adjusted Net Equity and 80% of Reference Funding, or 10 times the Adjusted Net Equity, with the required allocation (MA) calculated per the methodologies specified and, when both conditions are met, by adopting the higher resulting amount; and (iii) establish phased coefficients for the MA calculation under the 10-times threshold from July 1, 2026 to July 1, 2028. These changes will come into effect on June 1, 2026.

***Administrative Proceedings in the Brazilian National Financial System, the Brazilian Payment System and Capital Markets***

Law No. 13,506 of November 13, 2017 or "Law No. 13,506/17" applies to entities authorized or supervised by the Brazilian Central Bank or by the CVM, as well as to market participants. Some of the key aspects of Law No. 13,506 are that: (i) it increases the maximum fine applicable by the Brazilian Central Bank from R$250,000 to R$2 billion or 0.5% of the revenues of the company arising from services and financial products in the year prior to the violation; (ii) it increases the maximum fine applicable by the CVM from R$500,000 to R$50 million; (iii) it makes additional types of violations subject to penalties; (iv) it provides that the penalty of "public admonition" may be cumulative to other penalties applicable by the Brazilian Central Bank; (v) it provides that Brazilian Central Bank may enter into cease-and-desist commitments; and (vi) it provides that the Brazilian Central Bank and the CVM may enter into administrative agreements similar to leniency agreements.

***Opening, Maintenance and Closing of Deposit Accounts***

CMN Resolution No. 4,753/19 provides criteria for the opening, maintenance and closing of deposit accounts. The regulation determines that financial institutions must adopt procedures and controls that allow the verification and validation of the identity and qualification of the account holders and, if applicable, their representatives, as well as the authenticity of the information provided by the client. This information must be kept updated by the financial institution.

The rule also requires financial institutions to ensure, through the procedures and technology used for the opening, maintaining and closing of deposit accounts, the integrity authenticity and confidentiality, as well as the protection against unauthorized access, use, alteration, reproduction and destruction, of the information and the electronic documents used by them during the process.

***Issuance of Credit Instruments Electronically***

Law No. 13,986/2020, among other provisions, (i) created a new credit instrument, the Rural Real Estate Note (*Cédula Imobiliária Rural* or "CIR"), with the purpose of advancing rural real estate financing by the creation of an instrument specifically designed to that end; (ii) changed the rules governing Bank Deposit Certificates (*Certificado de Depósito Bancário* or "CDB"), especially regarding their issuance and the transfer of their ownership, by providing among other changes that CDB issued in book-entry form should be transferred by electronic endorsement, exclusively by means of a specific notation in the issuing institution's own electronic system or, when deposited in central depositary, by means of specific notation in the corresponding electronic system; and (iii) authorized that customary credit instruments such as the Agricultural Certificate of Deposit (*Certificado de Depósito do Agronegócio* – CDA), the Agricultural Warrant (*Warrant Agropecuário* – WA), the Real Estate Credit Certificate (*Certificado de Crédito Imobiliário* – CCI), the Bank Credit Note (*Cédula de Crédito Bancário* – CCB), the Rural Credit Note (*Cédula de Crédito Rural* – CCR), the Rural Promissory Note (*Nota Promissória Rural* – NPR), the Rural Trade Bill (*Duplicata Rural* – DR), may be issued in book-entry form through the electronic bookkeeping system held at a financial institution or other entity authorized by the Brazilian Central Bank to perform electronic bookkeeping activity.

*[**Table of Contents**](#toc)*<br>

On July 15, 2020, the Brazilian Central Bank regulated, through Circular No. 4,036/20, the electronic issuance of book-entry CCBs and CCRs by financial institutions. A financial institution must render the following services in respect of the bookkeeping of CCBs and CCRs: (i) issue the instrument in book-entry form at the request of the borrower; (ii) include all obligatory information related to CCBs and CCRs, as well as ancillary documents and/or information for the purposes of verifying the outstanding balance of the underlying credit transaction; (iii) verify the effective title or fiduciary title of the instruments; (iv) make the payment CCBs and CCRs for the settlement of obligations available to the debtor; (v) control the financial flow related to the CCBs and CCRs, including prepayments; (vi) record security interests in an entity authorized to perform centralized registration or deposit of financial assets; (vii) make information about the CCBs and CCRs available to debtors, holders, collateral beneficiaries or any other legally qualified interested party; and (viii) carry out the issuance of certificates regarding the instruments whenever required.

***Limitation to the Fees and Interest Rates on Overdraft-Secured Checks***

On November 27, 2019, the CMN issued Resolution No. 4,765 or "Resolution No. 4,765/2019," providing for new rules on the overdraft granted by financial institutions in checking accounts held by individuals and individual microentrepreneurs. The new rule limits the charging of fees on overdraft-secured checks to: (i) 0% for the opening credit facilities of up to R$500.00; and (ii) 0.25% for the opening of credit facilities larger than R$500.00, calculated with the amount of the facility that exceeds R$500.00. It also limits interest rates over the overdraft-secured check to up to 8% per month, to which must be added a discount of the overdraft fees already charged monthly by the financial institution. If the interest is less than or equal to the overdraft fees, such interest rates must be equal to zero. In addition, Resolution No. 4,765/2019 establishes that the overdraft-secured check must be compatible with the customer's risk profile.

Resolution No. 4,765/2019 came into force on January 6, 2020, for agreements executed after the referred date, came into force on June 1, 2020, for agreements executed prior to such date. Regarding the 8% limitation above, the rule applies to all contracts from January 6, 2020, regardless of the date the applicable contract was entered into.

***Automatic Debit of Banking Accounts***

On March 26, 2020, CMN issued Resolution No. 4,790, which sets forth new rules for the automatic debit payments from checking account and accounts designated for the payment of an individual's wages. The new rule sets forth that financial institutions should only process automatic debit payments upon prior and express authorization of the client, and provides for the procedures for the authorization and cancellation of automatic debit payments. The new rule came into force on March 1, 2021, CMN Resolution No. 4,790 repealed CMN Resolution No. 4,771. Under recent updates, CMN Resolution No. 5,251 and BCB Resolution No. 505, both issued on September 25, 2025, provided new requirements to require debit authorizations with corporate or non-regulated payees to follow Automated Pix rules and require depositary and recipient institutions to update contracts and related procedures.

***Taxation***

*Corporate Income Tax and Social Contribution Tax*

The IRPJ is calculated at a rate of 15.0%, plus a surtax of 10.0% which is levied on profits exceeding the amount of R$240,000 per year and the CSLL is calculated at a rate of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) 15% applicable to private insurance companies, securities distributors, foreign exchange and securities brokerage firms, real estate
credit companies, credit card administrators, leasing companies, credit cooperatives, and savings and loan associations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) 20% applicable to banks of any kind.

Payment institutions, organized over-the counter market administrators, stock/commodities/futures exchanges, clearing and settlement entities and other entities regulated by the CMN and are subject to a gradual increase of CSLL rate:

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 12% until December 31, 2027; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 15% as of January 1, 2028.

Credit, financing and investment companies and capitalization companies are also subject to a gradual increase of CSLL rate:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 17.5% until December 31, 2027;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 20% as of January 1, 2028.

Deferred tax assets and liabilities are measured based on temporary differences between the book basis and tax basis of assets and liabilities, tax losses, and adjustments to fair value of securities and derivatives. Pursuant to the current regulations, the expected realization of deferred tax assets is based on projections of future results and a technical study approved by the board of directors of Santander Brasil.

*IRPJ and CSLL on Foreign Exchange Variation of Hedges for Investments Held Abroad*

Pursuant to Law No. 14,031/2020, which came in force in July 2020, exchange rate variations arising from hedges on investments held abroad are taxable starting in 2021. Accordingly, in 2021, 50% of the exchange rate variation shall be taxable under the IRPJ and CSLL, while, as of 2022, 100% of the exchange rate variation will be considered as taxable.

*Tax on Services*

Each of the Municipalities of Brazil and the Federal District are responsible for establishing the applicable ISS rate, which is charged on the value of services provided by the company, to the municipality where the service renderer is located. The rates vary from 2% to 5% and depend on the nature of the service.

In line with federal legislation (Complementary Law No. 116/2003), ISS is due in the municipality where the service provider is headquartered, at rates ranging from 2% to 5%, depending on the type of service and the applicable municipal legislation.

*PIS and COFINS Tax Rates*

PIS and COFINS (respectively, the profit participation contribution and the social security financing contribution, both of which are social contributions due on certain revenues net of certain expenses) payable by financial institutions and similar entities, as defined by law, are due at the rate of 0.65% and 4%, respectively. They are levied cumulatively on gross revenue billed, which is defined as the total revenues earned by the legal entity, net of certain expenses, such as funding costs.

Nonfinancial entities are taxed at the rates of 1.65% and 7.6% of PIS and COFINS, respectively, and are subject to noncumulative incidence, which consists of deduction of certain expenses from the tax base as allowed by law.

Financial income from nonfinancial companies is taxed at the rate of 0.65% and 4%, respectively, pursuant Decree No 8,426/2015.

*FATCA*

The Foreign Account Tax Compliance Act, or "FATCA" became law in the United States on March 18, 2010. The legislation requires foreign financial institutions, or "FFIs," (such as Santander Brasil) to enter into an FFI agreement under which they agree to identify and provide the U.S. Internal Revenue Service, or "IRS," with information on accounts held by U.S. persons and certain U.S.-owned foreign entities, or otherwise face a 30% withholding tax on certain U.S. source withholdable payments.

In addition, FFIs that have entered into an FFI agreement will be required to withhold on such payments made to FFIs that have not entered into an FFI agreement, account holders who fail to provide sufficient information to classify an account as a U.S. or non-U.S. account, and U.S. account holders who do not agree to the FFI reporting their accounts to the IRS.

On September 23, 2014, Brazil and the United States announced that they entered into an intergovernmental agreement, or "IGA," which became effective in Brazil by virtue of Decree No. 8506 as of August 24, 2015. The aim of the IGA is to improve international tax compliance and implement FATCA. The IGA establishes an automatic annual bilateral exchange of information with the U.S. tax authorities. Under this agreement, Brazilian financial institutions will generally be required to provide certain information about their U.S. account holders to the Brazilian tax authorities (Receita Federal do Brasil), which will share that information with the IRS.

*[**Table of Contents**](#toc)*<br>

Complying with the required identification, withholding, and reporting obligations requires significant investment in an FFI's compliance and reporting framework. We are continuing to follow developments regarding FATCA closely and are coordinating with all relevant authorities.

*Common Reporting Standard*

On December 28, 2016, Normative Ruling No. 1,680 was enacted, introducing the Common Reporting Standard in Brazil. The Common Reporting Standard provides for certain account reporting obligations similar to those existing under FATCA. It was created in the context of the Organization for Economic Cooperation and Development's Base Erosion and Profit Shifting project, which is aimed at reducing tax avoidance. Normative Ruling No. 1,680 applies to legal entities required to present the e-Financeira pursuant to Normative Ruling No. 1,571, dated July 2, 2016.

On the same date, the Normative Ruling No. 1,681 was enacted providing for the obligation to annually deliver the "Country to Country Statement," an ancillary obligation also arising from the discussions under the BEPS Project, before the Brazilian Federal Revenue Service, or "RFB," as a measure to expand information exchange and improve the level of international tax transparency. This new regulation should not have any impact on Santander Brasil, since, as it is controlled by a legal entity resident in Spain, it is not required by the Brazilian regulation to present such statement.

*Income Tax Levied on Capital Gains*

Law No. 13,259, of March 16, 2016 or "Law No. 13,259/16" introduced the application of progressive tax rates for income taxation over capital gains recognized by Brazilian individuals and by holders that are not domiciled in Brazil for purposes of Brazilian taxation ("Non-Resident Holders") on the disposition of assets in general. Under Law No. 13,259/16, the income tax rates applicable to capital gains realized by these investors would be: (i) 15% for the portion of the gains up to R$5 million, (ii) 17.5% for the portion of the gain that exceeds R$5 million but does not exceed R$10 million, (iii) 20% for the portion of the gain that exceeds R$10 million but does not exceed R$30 million, and (iv) 22.5% for the portion of the gain that exceeds R$30 million.

The provisions of Law No. 13,259/16 may apply to Non-Resident Holders pursuant to Joint Resolution No. 13, provided such Non-Resident Holders are not located in a Tax Haven. However, Non-Resident Holders (whether they are considered to be Non-Resident Holders as a result of Joint Resolution No. 13 or otherwise) located in a Tax Haven are subject to a specific tax regulation and will continue to be taxed at a rate of 25%.

Most transactions carried out by Non-Resident Holders pursuant to Joint Resolution No. 13 and that result in capital gains are subject to taxation at a fixed 15% rate, provided they are not located in a Tax Haven.

The tax must be withheld and paid by the buyer or, in cases where the buyer and seller are domiciled abroad, a legal representative of buyer shall be designated for the payment of the tax.

*Deferred Tax Assets*

Law No. 14,467/2022 (with amendments by Law No. 15,078/2024) established the tax treatment for the receipt of credits arising from the activities of financial institutions and others authorized to operate by the Brazilian Central Bank. As of January 1, 2025, institutions will be able to deduct, when determining real profit and the calculation basis for the CSLL, losses incurred in the receipt of credits arising from activities related to defaulted transactions, regardless of the date of their contracting and transactions with a legal entity in bankruptcy proceedings or under judicial recovery, as of the date of the bankruptcy decree or the granting of judicial recovery.

The tax deduction established must observe the loss incurred according to the percentages established based on the period of default, losses incurred in an amount greater than the real profit cannot be deducted in the year 2025. From January 2026 onwards, losses determined on credits that were in default on December 31, 2024, and not yet deducted for tax purposes up to that date, may be excluded from net income, when determining real income and the CSLL calculation basis, at a rate of 1/84 (one eighty-fourth) for each month of the calculation period, and institutions may also opt, until December 31, 2025, irrevocably and irreversibly, to make deductions at a rate of 1/120 per month. According to Law No. 14,467/2022, entities had until December 31, 2025 which period would be used for the tax deduction of this balance.

*[**Table of Contents**](#toc)*<br>

The permanent decision was made by the administration in December 2025, and the study on the realization of tax credits considers 1/120 (10 years) for Banco Santander (Brasil) S.A., Santander Sociedade de Crédito, Financiamento e Investimento S.A., and Santander Leasing S.A. Arrendamento Mercantil, and considers 1/84 (7 years) for Banco RCI Brasil S.A. and Banco Hyundai Capital Brasil S.A.

***Disclosure Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act***

Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012, which added Section 13(r) to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), an issuer is required to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with individuals or entities designated pursuant to certain Executive Orders. Disclosure is generally required even where the activities, transactions or dealings were conducted in compliance with applicable law.

As we are part of the Santander Group, we must also disclose the exposure of other entities of the Santander Group to Iran. The following activities are disclosed in response to Section 13(r) with respect to the Santander Group and its affiliates. During the period covered by this report:

&nbsp;&nbsp;&nbsp;&nbsp;(a) *Frozen accounts and transactions*: A limited number of accounts for certain customers subsequently
designated over time by the US under the Specially Designated Global Terrorist (SDGT) sanctions program,were or are maintained with certain
non-U.S. affiliates of Santander. All such accounts have been frozen or cancelled to comply with applicable legal requirements.

&nbsp;&nbsp;&nbsp;&nbsp;(b) *Legacy contractual obligations related to guarantees*: The Santander Group also has certain legacy
performance guarantees for the benefit of an Iranian bank that is currently designated by the US under the Specially Designated Global
Terrorist (SDGT) sanctions program (stand-by letters of credit to guarantee the obligations – either under tender documents or under
contracting agreements – of contractors who participated in public bids in Iran) that were in place prior to April 27, 2007. The
Santander Group is not contractually permitted to cancel these arrangements without paying the guaranteed amount. As such, the Santander
Group intends to continue to provide the guarantees in accordance with company policy and applicable laws.

In the aggregate, all of the transactions described above resulted in gross revenues and net profits in the year ended December 31, 2025 which were negligible relative to the overall revenues and profits of Banco Santander, S.A. The Santander Group has undertaken significant steps to withdraw from the Iranian market such as closing its representative office in Iran and ceasing all banking activities therein, including correspondent relationships, deposit taking from Iranian entities and issuing export letters of credit, except for the legacy transactions described above.

**SELECTED STATISTICAL INFORMATION**

The following information for Santander Brasil is included for analytical purposes and should be read in conjunction with the consolidated financial statements and related notes contained elsewhere herein, as well as "Item 5. Operating and Financial Review and Prospects."

Average annual balance sheet data has been calculated based upon the average of the monthly balances at 13 dates: as of December 31 of the prior year and each of the month-end balances of the 12 subsequent months. Average income statement and balance sheet data and other related statistical information have been prepared on a consolidated annual basis.

The selected statistical information set forth below includes information as of and for the years ended December 31, 2025, 2024 and 2023 extracted from the audited financial statements prepared in conformity with IFRS as issued by the IASB. See "Presentation of Financial and Other Information" and "Item 3. Key Information—A. Selected Financial Data."

**Average Balance Sheet and Interest Rates**

The following tables show our average balances and interest rates for each of the periods presented. With respect to the tables below and the tables under "—Changes in Net Interest Income—Volume and Rate Analysis" and "—Assets—Earning Assets—Net Interest Spread," (i) we have stated average balances on a gross basis, before netting impairment losses, except for the total average asset figures, which include such netting, and (ii) all average data have been calculated using month-end balances, which is not significantly different from having used daily averages. We stop accruing interest on loans once they are more than 90 days past due. All our non-accrual loans are included in the table below under "—Other assets."

(1) In the year ended December 31, 2023, we revised the definition of marketable debt securities to include
the line items "Financial liabilities measured at fair value in income held for trading" and "Financial liabilities
at amortized cost," instead of only including "Financial liabilities at amortized cost." The amounts presented as of

The following tables present the changes in our net interest income allocated between changes in average volume and changes in average rate for the year ended December 31, 2025, compared to the year ended December 31, 2024, and for the year ended December 31, 2024 compared to the year ended December 31, 2023. We have calculated volume variances based on movements in average balances over the period and rate variance based on changes in interest rates on average interest-earning assets and average interest-bearing liabilities. We have allocated variances caused by changes in both volume and rate to volume. You should read the following tables and the footnotes thereto in light of our observations noted in "—Average Balance Sheet and Interest Rates."

(1) In the year ended December 31, 2023, we revised the definition of marketable debt securities to include
the line items "Financial liabilities measured at fair value in income held for trading" and "Financial liabilities
at amortized cost," instead of only including "Financial liabilities at amortized cost." The amounts presented as of
December 31, 2025, 2024 and 2023 reflect this change.

(\*) Yield information does not give effect to changes in fair value that are reflected as a component of stockholder's equity.

(1) Total earning assets plus dividends from companies accounted for by the equity method (equity instruments).

(2) Net interest income (Including equity instruments).

(3) Gross yield is the amount of "Interest and dividends on equity securities" divided by "Average
earning assets."

(4) Net interest margin is the amount of "Net interest income" divided by "Average earning
assets."

(5) Net interest spread is the difference between the average rate of "Total earning asset"
and the average rate of "Total interest-bearing liabilities."

(1) In the year ended December 31, 2023, we revised the definition of marketable debt securities to include
the line items "Financial liabilities measured at fair value in income held for trading" and "Financial liabilities
at amortized cost," instead of only including "Financial liabilities at amortized cost." The amounts presented as of
December 31, 2025, 2024 and 2023 reflect this change.

***Loan Portfolio***

As of December 31, 2025, our gross loans and advances to customers totaled R$602.0 billion (47.4% of our total assets). Net impairment losses, loans and advances to customers totaled R$564.5 billion as of December 31, 2025 (44.5% of our total assets). In addition to loans, we had outstanding loan commitments drawable by third parties totaling R$235.5 billion, R$205.3 billion and R$177.5 billion, as of December 31, 2025, 2024 and 2023, respectively.

*Types of Loans by Type of Customer*

The majority of the loans we have outstanding are to borrowers domiciled in Brazil and are denominated in *reais*. For each loan category, we maintain specific risk management policies that are in line with the standards of the Santander Group, which in turn, are managed and monitored by our board of officers through the credit committee. The credit approval process for each loan category is structured primarily around our business segments. See "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Credit Risk" for details on our credit approval policies for retail and wholesale lending.

Our loan portfolio does not have any specific concentration exceeding 10% of our total loans. As of December 31, 2025, 1.0% of our loan portfolio is allocated to our largest debtor and 3.3% to the next 10 largest debtors.

For further information about the breakdown of our Loans and Maturity see sections "a – Breakdown" and "b – Detail" of note "9 – Loans and advances to customers" to our audited consolidated financial statements included in this annual report.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Impairment losses on financial assets, net, as reported in our consolidated financial statements, reflect
net provisions for credit losses less recoveries of loans previously written off.

As of December 31, 2025, our allowance for impairment losses for the periods indicated amounted to R$40,694 million, an increase of R$5,025 million, or 14.1%, compared to R$35,669 million as of December 31, 2024. This increase reflects continued growth of our loan portfolio—particularly in SMEs, Auto Finance and Real Estate—combined with a disciplined and forward-looking approach to risk management, including prudent reserve strengthening among Individuals, especially in lower-income segments, and within Corporate & SMEs, primarily smaller companies.

As of December 31, 2024, our allowance for impairment losses for the periods indicated amounted to R$35,669 million, an increase of R$515.9 million, or 1.5%, compared to R$35,153 million as of December 31, 2023, which was primarily due to growth in our retail portfolio, offset by the decrease in provisioning due to the restructuring of the indebtedness of a large customer in our wholesale segment.

Balances are deemed to be impaired when there are reasonable doubts as to their full recovery and/or the collection of the related interest for the amounts on the dates indicated in the loan agreement, after taking into account the collateral guarantees received to secure (fully or partially) collection of the related balances.

As established in our internal renegotiation policy, in order for renegotiated products to be classified as performing, the customer must be in compliance with the terms of the relevant product for at least 12 consecutive months. Loan modifications are considered renegotiations when are originated from financial difficulties.

*[**Table of Contents**](#toc)*<br>

We increased our efforts regarding the collection of loans that are less than 90 days past due and also in relation to written-off loans. We are also continuing with our strategy of granting loans to persons with a low-risk profile and higher levels of collaterals and guarantees.

(1) Includ es as of December 31, 2025, R$18,548 million of doubtful
loans (R$15,912 million in 2024 and R$15,753 million in 2023) that were not past-due. Through the year ended December 31, 2024, we calculated
doubtful loans by reference to loans that were not past due but were subject to a default at some point during their term.

*Evolution of Impaired Assets*

Our impaired assets increased by 15.8%, or R$6,657 million, to R$48,900 million as of December 31, 2025, compared to R$42,242 million as of December 31, 2024. Provisions for impairment losses, including total recoveries of loans previously charged off, increased by 14.1%, or R$5,025 million, to R$40,694 million as of December 31, 2025, compared to R$35,669 million as of December 31, 2024. Offsetting these effects were recoveries of R$1,415 million on loans previously written off as of December 31, 2025, and R$994 million as of December 31, 2024.

We believe the provisions made were adequate to cover all known or reasonably probable losses or incurred losses in the credit portfolio of loans and other assets as of December 31, 2025.

The following table shows the changes in our impaired assets at the dates indicated:

---

| | | | |
|:---|:---|:---|:---|
|  | **As of December 31,** | **As of December 31,** | **As of December 31,** |
|  | **2025** | **2024** | **2023** |

| **Balance at end of year** | **48900** | **42242** | **39887** |

---

The amount of "net additions" for any period is assets that became impaired in that period less assets that were impaired but became performing in that period. In 2025, the debt restructuring options were improved to maintain consistent levels of "net additions" and "write-offs."

*Commercial and Industrial*

Impaired assets in the commercial and industrial loans portfolio amounted to R$17,291 million as of December 31, 2025, an increase of R$4,116 million, or 31.2%, compared to R$13,175 million as of December 31, 2024. This increase reflects continued growth in the SMEs portfolio, combined with a more challenging credit environment—driven by higher-for-longer interest rates—affecting Corporate & SMEs, primarily smaller companies.

Impaired assets in the commercial and industrial loans portfolio amounted to R$13,175 million as of December 31, 2024, a decrease of R$3,117 million, or 19.1% compared to R$16,292 million as of December 31, 2023. This decrease was mainly due to the restructuring of the indebtedness of a large customer in our wholesale segment.

*Real Estate*

Impaired assets in the real estate lending portfolio totaled R$1,809 million on December 31, 2025, an increase of R$73 million, or 4.2%, compared to R$1,736 million as of December 31, 2024. This was primarily due to a higher growth in this portfolio.

Impaired assets in the real estate lending portfolio totaled R$1,736 million on December 31, 2024, an increase of R$384 million, or 28.4%, compared to R$1,352 million as of December 31, 2023. This increase in impaired assets in this portfolio was primarily due to the growth of this portfolio and challenging macroeconomic conditions.

*Installment Loans to Individuals*

Impaired assets in the installment loans to individuals lending portfolio totaled R$29,779 million as of December 31, 2025, with an increase of R$2,495 million, or 9.1%, compared to 2024. This increase reflects continued growth in the Auto Finance and Real Estate portfolios, combined with a more challenging credit environment affecting Individuals—particularly in lower-income segments.

Impaired assets in the installment loans to individuals lending portfolio totaled R$27,284 million as of December 31, 2024, with an increase of R$5,045 million, or 22.7%, compared to 2023. This increase in impaired assets in this portfolio was primarily due to the growth of this portfolio, changes in the methodology applied to determine whether a loan is non-performing and challenging macroeconomic conditions affecting certain products such as our financial products and services aimed at rural customers.

*Lease Financing*

Impaired assets in the lease financing lending portfolio totaled R$21 million on December 31, 2025, a decrease of 56.2% or R$26 million, compared to R$47 million as of December 31, 2024.

Impaired assets in the lease financing lending portfolio totaled R$47 million on December 31, 2024, an increase of 1191.4%, or R$43 million, compared to R$4 million as of December 31, 2023. This increase in impaired assets in this portfolio was concentrated in two specific clients.

**Methodology for Impairment Losses**

We evaluate all loans regarding the provision for impairment losses from credit risk. Loans are either individually evaluated for impairment, or collectively evaluated by grouping similar risk characteristics. Loans that are individually evaluated for impairment losses are not evaluated collectively.

To measure the impairment loss on loans individually evaluated for impairment, we consider the conditions of the borrowers, such as their economic and financial situation, level of indebtedness, ability to generate income, cash flow, management, corporate governance and quality of internal controls, payment history, industry expertise, contingencies and credit limits, as well as the characteristics of assets, such as their nature and purpose, type, sufficiency and liquidity level guarantees and total amount of credit, as well as based on historical experience of impairment and other circumstances known at the time of evaluation.

To measure the impairment loss on loans collectively evaluated for impairment, we segregate financial assets into groups considering the characteristics and similarity of credit risk. In other words, according to segment, the type of assets, guarantees and other factors associated such as the historical experience of impairment and other circumstances known at the time of assessment.

The expected loss measurement is made through the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;• *Exposure at Default (EAD)*: is the amount of a transaction exposed to credit risk including the
ratio of current outstanding balance exposure that could be provided at default. Developed models incorporate hypotheses considering possible
modifications to the payment schedule.

&nbsp;&nbsp;&nbsp;&nbsp;• *Probability of Default (PD)*: is defined as the probability that the counterparty will be unable
to meet its obligations to pay the principal and / or interest. For IFRS 9 purposes, two types of PD are considered:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ PD - 12 months (Stage 1): The probability that the financial instrument will default within the next
12 months.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ PD – lifetime (Stages 2 and 3): The probability that the transaction will default between the
balance sheet date and the residual maturity date of the transaction.

The standard requires that relevant future information be considered when estimating these parameters.

&nbsp;&nbsp;&nbsp;&nbsp;• *Loss Given Default (LGD)*: is the loss produced in the event of default. In other words, this
reflects the percentage of exposure that could not be recovered in the event of a default. It depends mainly on the collateral, which
is considered as credit risk mitigating factors associated with each financial asset, and the future cash flows that are expected to be
recovered. According to the standard, forward-looking information must be taken into account in the estimation.

&nbsp;&nbsp;&nbsp;&nbsp;• *Discount rate*: the rate applied to the future cash flows estimated during the expected life of
the asset, and which is equal to the net present value of the financial instrument at its carrying value.

In order to estimate the above parameters, the Bank has applied its experience in developing internal models for parameters calculation both for regulatory and management purposes.

***Impaired Asset Ratios***

Our credit risk exposure portfolio totaled R$778.9 billion as of December 31, 2025, an increase of R$28.5 billion compared to R$750.4 billion as of December 31, 2024. Our impaired assets increased by R$6.7 billion in the same period, from R$42.2 billion to R$48.9 billion. The default rate increased by 0.6 p.p. in 2025 in comparison to 2024, reflecting a deterioration of credit in our individuals business, particularly among lower-income segments, and among Corporates & SMEs, driven by smaller companies.

***Allowance for credit losses to total loans outstanding***

In 2025, our allowance for credit losses to total loans outstanding credit ratio increased by 0.8 percentage points, from 5.9% as of December 31, 2024 to 6.8% as of December 31, 2025. This increase was primarily driven by a 14.1% rise in the allowance for credit losses and a 0.4% increase in total loans outstanding.

**Principal Factors Affecting Our Financial Condition and Results of Operations**

***Brazilian Macroeconomic Environment***

As a Brazilian bank, we are significantly affected by the general economic environment in Brazil. While Brazilian GDP increased in 2025, driven by fiscal incentives granted by the Brazilian government, historically low

unemployment levels and a strong performance in certain economic sectors, we cannot assure you that this trend will continue, especially given persistent fiscal challenges, elevated interest rates, global economic uncertainties, and

inflationary pressures influenced by domestic and international factors.

The Brazilian economic environment has historically been characterized by significant variations in economic growth, inflation and currency exchange rates. Our results of operations and financial condition are influenced by these factors and the effect that these factors have on employment rates, the availability of credit and average wages in Brazil. The following table presents key data of the Brazilian economy for the periods indicated:

Despite the approval of a new fiscal framework and some measures to increase tax revenues, prospects for public expenditures to continue growing over time and for the economy to slow down into the future have stoked fears in financial markets about Brazil's already high public debt. This has resulted in a persistent risk premium, a limitation in the room for the Brazilian *real* to strengthen and volatility in financial asset prices. Brazil's economy was also severely affected by the COVID-19 pandemic starting in 2020. Brazilian GDP recovered to an extent in 2021, in part as a result of Brazil's ongoing vaccination program and the relaxation of certain restrictions allowing a progressive resumption of economic activities, as set out under "—Impact of COVID-19" below, but considerable uncertainty remains as to the duration and severity of the COVID-19 pandemic and its economic effects. In 2022, the relaxation of COVID-19 restrictions and continued fiscal incentives granted by Brazilian government supported Brazilian GDP growth, which reached 3.0% in 2022. In 2023, fiscal incentives continued to have an important effect, but the contribution of a record harvest of grains was key for the Brazilian GDP to have increased 3.2% in the period. In 2024, in response to the payment of a sizeable volume of delayed court-ordered debts in the first half of 2024, the maintenance of fiscal incentives, historically low unemployment levels and a strong performance in certain economic sectors, the Brazilian economy grew 3.4%.

*[**Table of Contents**](#toc)*<br>

In 2025, Brazil faced high inflation, elevated interest rates, a less favorable global economic environment and continued geopolitical uncertainty stemming from the war in Ukraine and tensions in the Middle East. In addition, commodity-related sectors did not contribute to economic growth to the same extent as in the recent past, and monetary policy remained tight as inflation stayed above the target range and fiscal pressures persisted. As a result of these factors, GDP growth in 2025 was lower than in 2024. Any slowdown in Brazil's economic growth, or adverse changes in interest rates, unemployment levels or general price stability, could adversely affect our business, financial condition and results of operations. In 2026, Brazil's macroeconomic environment is expected to be characterized by moderate growth, supported by residual fiscal stimulus and the initial phase of monetary easing. Even so, activity remains constrained by high structural capital costs, tighter credit conditions and a smaller statistical carry-over from the previous year. Inflation continues to ease gradually, driven by lower food prices and the lagged effects of restrictive monetary policy, although projections and expectations remain above the official target range. The labor market shows early signs of softening after several years of resilience, and the exchange rate is likely to operate under a more volatile global backdrop as the broad depreciation of the U.S. dollar observed in 2025 is not expected to continue.

Externally, Brazil's financing needs should decline as import growth moderates and foreign direct investment remains solid, but the international environment remains less favorable due to slower global growth, persistent geopolitical fragmentation and mixed commodity dynamics. At the same time, fiscal challenges persist, with public debt expected to rise further despite compliance with the fiscal framework. Any deterioration in economic activity, higher-than-expected inflation or interest rates, reduced credit availability or increased volatility in global markets could adversely affect Brazil's macroeconomic outlook and, consequently, our business, financial condition and results of operations.

For more information, see "Item 3. Key Information—D. Risk Factors—Risks Relating to Brazil and Macroeconomic and Political Conditions in Brazil and Globally—Inflation, government efforts to control inflation, and changes in interest rates may hinder the growth of the Brazilian economy and could have an adverse effect on us."

***War in Ukraine and uncertainties following the ceasefire agreement in the Middle East***

The persistence of the war between Russia and Ukraine has continued to cause humanitarian problems in Europe as well as volatility in financial markets globally, heightened inflation, shortages and increases in the prices of energy, oil, gas and other commodities. In response to the war in Ukraine, several countries, including the United States, the European Union member states, the United Kingdom and other UN member states, have imposed severe sanctions on Russia and Belarus. Furthermore, we believe that the risk of cyberattacks on companies and institutions has increased and could increase even further as a result of the above-mentioned conflicts and in response to the sanctions imposed, which could adversely affect our ability to maintain or enhance our cybersecurity and data protection measures. The continuance or escalation of the war, including any extension to other countries in the region, has led to, and could continue to lead to, further increases in energy prices, including oil and gas (particularly if supplies to Europe are interrupted), and inflationary pressures, which in turn could lead to higher interest rates and market volatility. In addition, the war has exacerbated supply chain problems, particularly for those businesses most sensitive to rising energy prices. The war and its effects have exacerbated and could continue to exacerbate the slowdown in the global economy and could negatively affect the ability of some of our customers to meet their obligations, especially those with more exposure to the Russian or Ukrainian markets.

The conflict between Israel and Hamas has also stoked fears about a broader war in the Middle East and the impact this could have on the global economy generally and oil markets in particular.

While we do not have a physical presence in Russia, Ukraine or in the Middle East, and our direct exposure to Russian, Ukrainian or Middle Eastern markets and assets is not material, the impact of the war in Ukraine and uncertainties following the ceasefire agreement in the Middle East, and the related sanctions imposed on global markets and institutions, the impact on macroeconomic conditions generally, and other potential future geopolitical tensions and consequences arising from the war remain uncertain and may exacerbate our operational risk. For more information, see "Item 3. Key Information—D. Risk Factors—Risks Relating to Brazil and Macroeconomic Conditions in Brazil and Globally—Geopolitical conflicts and related uncertainties, such as the continuance or escalation of the war in Ukraine and the uncertainties following the ceasefire agreement in the Middle East, could materially affect our financial position and increase our operational risk."

***Interest rates***

In 2021, the Brazilian Central Bank began a monetary tightening cycle in response to rising inflation, the depreciation of the *real*, and a perception of recovery in certain economic activities following the easing of COVID-19-related restrictions. The SELIC rate increased from 9.25% as of December 31, 2021, to 13.75% as of December 31, 2022 (the highest level since the end of 2016). In 2023, the Brazilian Central Bank initiated an easing cycle as inflationary pressures subsided, reducing the SELIC rate to 11.75% as of December 31, 2023. The easing continued into the first half of 2024, with the SELIC rate reaching 10.50% in May 2024. However, inflationary pressures resurfaced in mid-2024, driven by adverse climatic conditions affecting food and energy prices, a significant devaluation of the *real* following the U.S. presidential election, and persistent fiscal challenges in Brazil. In response, the Brazilian Central Bank resumed tightening monetary policy, increasing the SELIC rate to 11.25% in November 2024 and 12.25% in December 2024. These adjustments reflect the Brazilian Central Bank's efforts to balance inflation control with economic stability amid elevated interest rates globally and domestic economic concerns. In 2025, the Brazilian Central Bank continued to raise the SELIC rate, which reached 15.00% in mid-2025, as part of its efforts to address elevated inflation and inflation expectations. The SELIC rate was maintained at that level through the end of 2025. As of the date of this annual report, the SELIC rate is 15.00%.

An increase in the SELIC rate may adversely affect us by reducing the demand for our credit and investment products, increasing funding costs, and increasing in the short run the risk of default by our customers. Conversely, a decrease in the SELIC rate may have a positive impact on our operations by promoting volume growth, even though it may also create pressure on asset-side spreads, while liability spreads should remain stable or even improve.

The following table presents the low, high, average and period end SELIC rate since 2021, as reported by the Brazilian Central Bank:

Our assets are predominantly fixed rate and our liabilities are predominantly floating. The resulting exposure to increases in market rates of interest is modified by our use of cash flow hedges to convert floating rates to fixed, but we maintain an exposure to interest rate movements. For more information about our market risk, see "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Credit Risk."

***Credit Volume and Quality in Brazil***

In 2023, outstanding credit increased at a slower rate than in 2022 as the SELIC rate continued moving higher in that period. However, the ratio of nonperforming loans to individuals managed to remain nearly unchanged as a result of an increase in the income stemming from tight labor market conditions and a government-sponsored initiative for banks to renegotiate part of the credit in arrears (5.6% in 2023 as compared to 5.9% in 2022). In 2024, in response to tight labor market conditions and the extension of fiscal incentives by the Brazilian federal government, outstanding credit expanded 10.9% as compared with the previous year, while the ratio of nonperforming loans to individuals fell to 3.5% (from 3.7% in December 2023). However, this combination did not prevent an increase in the household debt burden in the period (24.2% in 2024 as compared to 23.8% in 2023). In 2025, higher interest rates, slower economic growth and renewed inflationary In 2025, higher interest rates, slower economic growth and renewed inflationary indebtedness remained issues amid tighter monetary and fiscal conditions.

***Foreign Exchange Rates***

Our policy is to maintain limited foreign exchange rate exposure by seeking to match foreign-currency-denominated assets and liabilities as closely as possible, including through the use of derivative instruments. In 2025, we recorded foreign exchange negative exposure of R$44.0 million, compared to foreign exchange exposure of R$34.0 million in 2024 and R$62.9 million in 2023. These results were due to the variation of the U.S. dollar against the *real* on our asset and liability positions in U.S. dollar-denominated instruments during these years. These foreign exchange gains and losses were offset in large part in each year by a corresponding loss or gain on derivatives entered into to hedge this exposure. Such losses and gains are recorded under "Exchange differences (net)." For further information see "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Results of Operations for the Years Ended December 31, 2025, 2024 and 2023—Results of Operations—Gains (losses) on Financial Assets and Liabilities (net) and Exchange Differences (net).

The Brazilian currency has, during the last decades, experienced frequent and substantial variations in relation to the U.S. dollar and other foreign currencies. In 2023, the R$/U.S.$ exchange rate fluctuated between R$4.7202 and R$5.4459 per U.S.$1.00. As of December 31, 2023 the exchange rate was R$4.8413 per U.S.$1.00. The exchange rate experienced significant volatility in 2024, driven by international factors (such as uncertainty about the conduct of monetary policies in advanced economies and the aggravation of geopolitical tensions) and domestic issues (such as concerns regarding fiscal policy and delays in the approval of important legislative measures), fluctuating between R$4.5293 and R$6.1991 per U.S.$1.00. In 2025, the *real* continued to exhibit volatility in response to global financial conditions and domestic fiscal concerns, with the exchange rate fluctuating between R$5.2729 and R$6.2086 per U.S. $1.00. As of December 31, 2025, the exchange rate was R$5.5024 per U.S.$1.00.

Depreciation of the *real* relative to the U.S. dollar has created additional inflationary pressures in Brazil, which has led to increases in interest rates and limited Brazilian companies' access to foreign financial markets, and prompted the adoption of recessionary policies by the Brazilian government. In 2023, as inflationary pressures of 2022 decreased, the Brazilian Central Bank began to reduce the SELIC rate from 13.75% (the highest level since the end of 2016) to 10.50% in May 2024. Depreciation of the *real* due to international and domestic issues combined with inflationary pressures resulting from adverse climate events affecting food and energy supplies, led the Brazilian Central Bank to resume a monetary tightening cycle in September 2024, which pushed the SELIC rate up to 15.0% by mid-2025. In 2025, the SELIC rate stood at 15.00% as the Brazilian Central Bank maintained a restrictive monetary stance in light of persistent inflationary pressures and exchange-rate volatility.

***Inflation***

In recent years, inflation has oscillated around the CMN's target, set annually by the CMN. However, recent inflationary shocks have pushed Brazil's inflation rate above the target in the past few years. From 2005 to 2018, the target level was 4.5%, with a tolerance interval of 2.0 percentage points until 2016, when the tolerance band was narrowed to 1.5 percentage points. The CMN subsequently lowered the target to 4.25% in 2019, with 0.25 percentage point decreases implemented annually until it reaches 3.00%. In June 2023, the CMN made the 3.00% inflation target permanent for subsequent years.

*[**Table of Contents**](#toc)*<br>

In 2019, as a result of temporary price shocks affecting edible items, inflation ended the year slightly above the targeted level, at 4.31%. In 2020, inflation increased to 4.5%. In 2021, inflation continued to accelerate and reached 10.06% at the end of the year, as a result of several shocks that ranged from problems in global supply chains – which increased prices at the wholesale level – to climate setbacks – which hit energy and foodstuff prices –, as well as continued depreciation of the Brazilian *real*. Similarly to what happened in the beginning of 2018, the Brazilian Central Bank delivered a letter to the CMN explaining why it failed to meet the inflation target and what actions would be implemented to ensure that inflation would converge to target in coming years. In 2022, inflationary pressures escalated in Brazil, including as a result of the ongoing war between Ukraine and Russia, supply chain issues, the continued COVID-19 pandemic (particularly in China) and increases in energy prices. As a result, inflation peaked in 2022 at multiple-year highs of 12.1% in Brazil in April 2022 (as measured by the IPCA in year-over-year terms) and 9.1% in the United States in June 2022 (as measured by the Consumer Price Index), the highest levels since 2003 in Brazil and 1981 in the United States. Accumulated inflation for the year ended December 31, 2022, was 5.79% in Brazil and 6.5% in the United States. This resulted in tighter monetary policy by the Brazilian Central Bank, which increased the SELIC rate from a low of 2.0% as of the end of 2020 to 13.75% as of August 2022, a level at which it remained until August 2023, when the Brazilian Central Bank decided to start loosening monetary policy as inflation began to improve as a result of favorable climatic conditions that lowered the prices of foodstuffs and the delayed effects of the Brazilian Central Bank's tightening of monetary policy. Accumulated inflation for the year ended December 31, 2023, was 4.6% in Brazil, although it remained above the targeted level of 3.25% set by the CMN. In early 2024, inflation initially followed a downward trend and reached as low as 3.7% in April 2024. However, inflation increased again during 2024 as a result of droughts which disrupted food supplies, increases in energy prices rose, and the depreciation of the *real* due to both domestic factors, including fiscal challenges, and global factors such as U.S. monetary policy and trade tensions. As a result, inflation reached 4.8% by the end of 2024, above the 3.0% target set by the CMN.

In 2025, inflation remained elevated relative to the CMN's target range, reflecting the combined effects of persistent services inflation, exchange-rate volatility and continued pressures on food and energy prices. Accumulated inflation for the year ended December 31, 2025 was 4.3%, compared to 4.8% in 2024.

The majority of our income, expenses, assets and liabilities are directly tied to interest rates. Therefore, our results of operations and financial condition are affected by inflation, interest rate fluctuations and related government monetary policies, all of which may materially and adversely affect the growth of the Brazilian economy, our loan portfolios, our cost of funding and our income from credit operations. We estimate that, in 2025, a 1.0% increase or decrease in the base interest rate would have resulted in a decrease or increase, respectively, in our net interest income of R$369 million within a one-year period. Any changes in interest rates may negatively impact our business, financial condition and results of operations. In addition, increases in base interest rates may adversely affect us by reducing the demand for our credit and investment products, increasing funding costs, and increasing in the short run the risk of default by our customers.

Inflation adversely affects our personnel and other administrative expenses that are directly or indirectly tied to inflation indexes, such as the IPCA, and the IGP-M. For example, considering the amounts in 2025, each additional percentage point change in inflation would impact our personnel and other administrative expenses by approximately R$116 million and R$88 million, respectively.

***Reserve and Lending Requirements***

The requirements set by the Brazilian Central Bank for reserves and credit has a significant impact on the results of operations of the financial institutions in Brazil. Increases or decreases in such requirements may have an impact on our results of operations by limiting or expanding the amounts available for commercial credit transactions.

*[**Table of Contents**](#toc)*<br>

The table below shows the requirements for reserves and credit to which we are subject for each financing category:

***Taxes***

See "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulation—Taxation."

***Goodwill of Banco Real***

We generated goodwill of R$27 billion as a result of our acquisition of Banco Real in 2008. Under IFRS, we are required to analyze goodwill for impairment at least annually or whenever there are indications of impairment. In 2025, 2024 and 2023, the recoverable goodwill amounts are determined from "value in use" calculations. For this purpose, we estimate cash flow for a period of five years. We prepare cash flow estimates considering several factors, including: (i) macroeconomic projections, such as interest rates, inflation and exchange rates, among others, (ii) the performance and growth estimates of the Brazilian financial system, (iii) increased costs, returns, synergies and investment plans, (iv) the behavior of customers, and (v) the growth rate of, and long-term adjustments to, cash flows. These estimates rely on assumptions regarding the likelihood of future events, and changing certain factors could result in different outcomes. The estimate of cash flows is based on valuations prepared by an independent research company, which is reviewed and approved by the board of directors. Amortization of goodwill for tax purposes generates a permanent difference and, as a result, no record of the deferred tax liability.

*[**Table of Contents**](#toc)*<br>

The following table shows the main assumptions for the basis of valuation as of the dates indicated.

---

| | | | |
|:---|:---|:---|:---|
|  | **As of December 31,** | **As of December 31,** | **As of December 31,** |
|  | **2025** | **2024** | **2023** |
|  | **(Value in use: cash flows)** | **(Value in use: cash flows)** | **(Value in use: cash flows)** |
| **Main Assumptions(\*)** |  |  |  |
| Basis of valuation |  |  |  |
| Period of the projections of cash flows(1) | 5 years | 5 years | 5 years |
| Growth rate(1) | 4.0% | 4.5% | 5.4% |
| Discount rate (2) | 12.2% | 13.6% | 13.0% |
| Discount rate before tax (2) | 18.5% | 20.8% | 20.3% |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) The projections of cash flow are prepared using internal budget
and growth plans of management, based on historical data, market expectations and conditions such as industry growth, interest rate and
inflation.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The discount rate is based on the capital asset pricing model.

(\*) A quantitative goodwill impairment test is performed annually. At the end of each exercise, an analysis is carried out on the existence of appearances of disability. For the years 2025, 2024 and 2023, there was no evidence of impairment. In the goodwill impairment test, carried out considering the December 2025 scenario, and whose discount rates and perpetuity growth are the most sensitive assumptions for calculating the present value (value in use) of discounted future cash flows, it was found that these continue to indicate the absence of impairment.

We performed a sensitivity test in the goodwill impairment analysis considering the main assumptions that could reasonably be expected to possibly change, as required by the IFRS. Accordingly, we applied such a test considering the discount rate and perpetuity growth rate as the main assumption subject to reasonably possible change and we did not identify any impairment to goodwill.

**Other Factors Affecting the Comparability of Our Results of Operations**

In addition, our results of operations have been influenced and will continue to be influenced by the other transactions and developments discussed under "Item 4. Information on the Company—A. History and Development of the Company—Important Events."

**Critical Accounting Policies**

Our consolidated financial statements have been prepared in accordance with IFRS as issued by the IASB.

***General***

Our main accounting policies are described in note 2 to our audited consolidated financial statements. The following discussion describes areas that require use of certain critical accounting estimates and the exercise of judgement regarding matters that are inherently uncertain and that impact our financial condition and results of operations. In this regard, if management decides to change these estimates, or apply such estimates for different durations a material impact on our financial condition and results of operations could result.

Management bases its estimates and judgments on historical experience and on various other factors and circumstances, which are believed to be reasonable. Actual results may differ from these estimates if assumptions and conditions change. Any judgments or changes in assumptions are submitted to the audit committee and to our regulatory authorities and are disclosed in the related notes to our audited consolidated financial statements, included elsewhere in this annual report.

*[**Table of Contents**](#toc)*<br>

***Fair Value of Financial Instruments***

We record a financial asset as measured at (i) fair value through profit or loss, (ii) fair value through other comprehensive income or (iii) amortized cost. In general, financial liabilities are measured at amortized cost. Exceptions include financial liabilities measured at: (i) fair value through profit or loss, (ii) other financial liabilities at fair value through profit or loss and (iii) financial liabilities designated as hedge items (or hedging instruments) measured at fair value. See "Item 3. Key Information—A. Selected Financial Data—Balance Sheet Data."

The fair value of a financial instrument is the price that would be received to sell an asset, or the amount paid to transfer a liability between market participants, in a transaction on the date of which fair value is measured, regardless of whether that price is directly observable or estimated using another valuation technique.

In estimating the fair value of an asset or a liability, we take into account relevant characteristics if market participants would also consider the same when pricing the asset and liability at the time fair value is measured. An assumed transaction like this establishes an asset sale price or transfer cost for the liability. In the absence thereof, price is established using valuation techniques commonly used by financial markets.

We use derivative financial instruments for both trading and nontrading activities. The main types of derivatives used are interest rate swaps, options and future rate agreements; foreign exchange forwards, futures, options, and swaps; cross-currency swaps; equity index futures; and equity options and swaps. The fair value of exchange-traded derivatives is calculated based on published price quotations. The fair value of over-the-counter derivatives is calculated as the sum of expected future cash flows arising from the instrument, discounted to the ("present value" or "theoretical close") at the date fair value is measured using techniques commonly applied by financial markets as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• The present value method is used for financial instruments permitting static hedging (principally, forwards
and swaps), loans and advances. This method uses expected future cash flows that are discounted through interest rate curves of the applicable
currencies. These interest rate curves are generally observable market data.

&nbsp;&nbsp;&nbsp;&nbsp;• The Black-Scholes model is used to value financial instruments requiring dynamic hedging (principally
structured options and other structured instruments). Certain observable market inputs are used in the model to generate variables such
as the bid-offer spread, exchange rates, volatility, correlation between indexes and market liquidity, as appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;• The present value method and the Black-Scholes model are used for valuing financial instruments exposed
to interest rate risk, such as interest rate futures, caps and floors. Main inputs used in these models are principally observable market
data, including appropriate interest rate curves, volatilities, correlations and exchange rates.

&nbsp;&nbsp;&nbsp;&nbsp;• The determination of fair value requires us to make certain estimates and assumptions. If quoted market
prices are unavailable, fair value is then calculated using widely accepted pricing models that consider contractual terms and prices
of the underlying financial instruments, yield curves, observable market data and other relevant factors. The use of different estimates
or assumptions in these pricing models could lead to a different valuation being recorded in our consolidated financial statements.

See note 2e (i) to our audited consolidated financial statements included elsewhere in this annual report for additional information on valuation techniques, details on our modeled main assumptions and estimates and a sensitivity analysis for the valuation of financial instruments to those changes in main assumptions and estimates and note 46.c.8 of our consolidated financial statements for a sensitivity analysis relating to the valuation of financial instruments to those changes in main assumptions.

***Impairment Losses on Financial Assets***

*Definition*

A financial asset is considered impaired when there is objective evidence that shows events have occurred which:

&nbsp;&nbsp;&nbsp;&nbsp;• give rise to an adverse impact on future cash flows estimated at the transaction date, in the case of
debt instruments (loans and debt securities);

&nbsp;&nbsp;&nbsp;&nbsp;• for equity instruments, their carrying amount may not be fully recovered;

&nbsp;&nbsp;&nbsp;&nbsp;• arise from the violation of terms of loans; and

&nbsp;&nbsp;&nbsp;&nbsp;• during the bankruptcy process.

As a general rule, the value adjustment of impaired financial instruments is recognized in the consolidated income statement for the period in which the impairment becomes evident. The reversal, if any, is recognized in the same manner for previous statements for which the impairment is reversed or reduced. Financial assets are deemed to be impaired, and the accrued interest suspended, when there are reasonable doubts as to their full recovery and/or the collection of the related interest for the amounts and on the dates indicated in the loan agreement after taking into account collateral guarantees received to secure (fully or partially) the collection of related balances.

For all nonperforming past due assets, any collections relating to impaired loans and advances are used to recognize the accrued interest. The remainder, if any, is applied to reduce the principal amount outstanding Debt Instruments Carried at Amortized Cost.

*Debt Instruments Carried at Amortized Cost*

The impairment loss amount incurred for determining a recoverable amount on a debt instrument measured at amortized cost is equal to the difference between its carrying amount and the present value of its estimated future cash flows (excluding future credit losses not incurred). This cash flow is discounted to the financial asset's original effective interest rate (or the effective interest rate at initial recognition), which is presented as a reduction of the asset balance and recorded on income statements.

In estimating the future cash flows of debt instruments, the following factors are taken into account:

&nbsp;&nbsp;&nbsp;&nbsp;• all amounts that are expected to be obtained over the remaining life of the instrument, (such as provided
guarantees);

&nbsp;&nbsp;&nbsp;&nbsp;• impairment loss considers the likelihood of collecting accrued interest receivable;

&nbsp;&nbsp;&nbsp;&nbsp;• various types of risk to which each instrument is subject;

&nbsp;&nbsp;&nbsp;&nbsp;• circumstances in which collections will foreseeably be made; and

&nbsp;&nbsp;&nbsp;&nbsp;• that cash flows are subsequently discounted using the instrument's effective interest rate.

A debt instrument is impaired due to insolvency when there is evidence of deterioration in the obligor's ability to pay, either because such obligor is in arrears or for other reasons. An example is recoverable losses resulting from a materialization of the insolvency risk of obligors (credit risk).

We have certain policies, methods and procedures for minimizing our exposure to counterparty insolvency. These policies, methods and procedures are applied in the granting, examination and documentation of debt instruments, contingent liabilities and commitments; identification of recoverable amounts and calculation of amounts necessary to cover the related credit risk.

The procedures employed in the identification, measurement, control and reduction of exposure to credit risk, are applied on an individual basis or through grouping similar credit risk characteristics.

Customers with individual management include wholesale segment customers, financial institutions and certain companies. Risk management is performed through an analysis complemented by tools to support a decision-making model based on credit risk assessment using internal procedure.

Customers with standardized management include individuals and companies not classified as individual customers. Risk management models are based on automated decision-making and risk assessment procedures, which are complemented by teams of analysts specializing in credit risk. The credits related to standardized customers are usually considered to be not recoverable when they have experience of historical loss and a delay greater than 90 days.

***Methodology for Impairment Losses***

We evaluate all loans in respect of the provision for impairment losses from credit risk. Loans are either individually evaluated for impairment or collectively evaluated by grouping similar risk characteristics for loans accounted as amortized cost. Loans that are individually evaluated for impairment losses are not evaluated collectively.

*[**Table of Contents**](#toc)*<br>

To measure the impairment loss on loans individually evaluated for impairment, we consider borrower conditions, such as their economic and financial situation; level of indebtedness; ability to generate income; cash flow; management; corporate governance and quality of internal controls; payment history; industry expertise; and contingencies and credit limits. The characteristics of assets are also considered, which include: the nature and purpose; type; sufficiency and liquidity level guarantees; total amount of credit; historical experience of impairment; and other circumstances known at the time of evaluation.

To measure the impairment loss on loans collectively evaluated for impairment, we segregate financial assets into groups considering the characteristics and similarity to credit risk, or in other words, according to segment, the type of assets, guarantees and other factors associated such as the historical experience of impairment and other circumstances known at the time of assessment.

Impairment loss is calculated using statistical models that consider the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;• Exposure at Default or "EAD," is the amount of risk exposure at the date of default by the
counterparty. In accordance with IFRS, the exposure at default used for this calculation is also the current exposure, as reported in
the balance sheets.

&nbsp;&nbsp;&nbsp;&nbsp;• Probability of Default or "PD," is the probability of the borrower failing to meet its principal
and/or interest payment obligations, PD is measured using an annual time horizon to quantify the probability of the borrower defaulting
in the coming year. A loan is in default if either the principal or interest is past due by ninety days or more or the loan is current
but there are doubts as to the solvency of the counterparty (subjective doubtful assets).

&nbsp;&nbsp;&nbsp;&nbsp;• Loss Given Default, or "LGD," is the loss arising in the event of default, LGD calculation
is based on the net charge offs on defaulted loans, taking into account the guarantees/collateral associated with the loans, the income
and expenses associated with the recovery process and the timing of default.

&nbsp;&nbsp;&nbsp;&nbsp;• Loss Identification Period, or "LIP," is the time period between the occurrence of a loss
event and the identification of an objective evidence of this loss. In other words, it represents the time horizon from the credit loss
occurrence until the effective confirmation of such loss.

Moreover, prior to loans be written-off (which is only done after the Bank has completed all recovery efforts and after about 360 days late), a fully registered provision (allowance for loan losses) of the loan's remaining balance applies. As a result, this provision fully covers the losses. Thus, the Bank understands that its loan loss allowance methodology has been developed to meet its risk metrics and capture loans that could potentially become impaired.

*Impairment*

Certain assets, such as intangible assets, including goodwill, equity method investments, financial assets not carried at fair value through profit or loss and other assets are subject to impairment review. We record impairment charges when we believe there is objective evidence of impairment, or that the cost of the assets may not be recoverable.

The assessment of what constitutes an impairment is based on the following models:

We test goodwill for impairment on an annual basis, or more frequently if events or changes in economic circumstances, such as an adverse change in Santander Brasil's business condition or observable market data, indicate that these assets may be impaired. The recoverable amount determination used in the impairment assessment requires prices of comparable businesses, present value or other valuation techniques, or a combination thereof, requiring management to make subjective judgments and assumptions. Events and factors that may significantly affect estimates include, among other things, competitive forces, customer behaviors and attrition, changes in revenue growth trends, cost structures and technology, and changes in discount rates and specific industry or market sector conditions. If an impairment loss is recognized for goodwill, it may not be reversed in a subsequent period. The recognition of impairment is applicable when significant changes occur in the main estimates used to evaluate the recoverable amounts of the cash-generating unit recoverable amount below the carrying amount. Based on the assumptions described above, no impairment of goodwill was identified in 2025, 2024 and 2023. Given the level of uncertainty related to these assumptions, our officers carry out a sensitivity analysis using reasonably possible changes in the key assumptions on which the recoverable amount of the cash-generating units are based in order to confirm that the recoverable amounts still exceed the carrying amounts.

*[**Table of Contents**](#toc)*<br>

All debt and equity securities (other than those carried at fair value through profit or loss) are subject to impairment testing every reporting period. The carrying value is reviewed in order to determine whether an impairment loss has been incurred.

Evaluation for impairment includes both quantitative and qualitative information. For debt securities, such information includes actual and estimated incurred credit losses indicated by payment default, market data on (estimated) incurred losses and other current evidence that the issuer may not pay amounts when due. Equity securities are impaired when management believes that, based on a significant or prolonged decline of fair value below the acquisition price, there is sufficient reason to believe that the acquisition cost may not be recovered, "Significant" and "prolonged" are interpreted on a case-by-case basis for specific equity securities.

Upon the impairment of either debt or equity instruments, the amount considered as effective loss is recognized in profit or loss. In addition, we did not identify any impairment of property, plant and equipment in 2025, 2024 and 2023 (see notes 14, 13 and 12, respectively, to our audited consolidated financial statements included elsewhere in this annual report).

**Post-employment Benefit Plan**

The post-employment benefit plan includes the following obligations undertaken by us: (i) to supplement the public social security system benefits, and (ii) medical assistance in the event of retirement, permanent disability or death for eligible employees and their direct beneficiaries.

***Defined Contribution Plan***

A defined contribution plan is the post-employment benefit plan for which we and our controlled entities as employers make pre-determined contributions to a separate entity and, in turn, have no legal or constructive obligation to pay further contributions if the separate entity does not hold sufficient assets to honor all benefits relating to the services rendered in the current and prior periods.

These contributions are recognized as personnel expenses in the consolidated income statement.

***Defined Benefit Plan***

A defined benefit plan is the post-employment benefit plan as is shown in note 21 to our audited consolidated financial statements. For this type of plan, the sponsoring entity's obligation is to provide the agreed benefits to employees, assuming the potential actuarial risk that benefits will cost more than expected.

The amendment of IAS 19 established fundamental changes in the accounting for and disclosure of employee post-employment benefits such as removing the mechanism of the corridor approach for recording of the obligation of the plans. Fundamental changes also include changes in the criteria for recognition of conventional interest of plan assets (valuation based on the discount rate actuarial liability).

The adoption of this accounting policy involved, fundamentally, full recognition of liabilities on account of actuarial losses (actuarial deficit) not recognized previously, against the stockholders' equity (Statements of Comprehensive Income).

Main Definitions:

&nbsp;&nbsp;&nbsp;&nbsp;• The present value of the defined benefit obligation is the present value of expected future payments
required to settle the obligation resulting from employee service in the current and past periods, without deducting any plan assets.

&nbsp;&nbsp;&nbsp;&nbsp;• Deficit or surplus is: (a) the present value of the defined benefit obligation, less (b) the fair value
of plan assets.

&nbsp;&nbsp;&nbsp;&nbsp;• The sponsoring entity may recognize the plan's assets in the balance sheet when they meet the
following characteristics: (i) the assets of the fund are sufficient to meet all employee benefit plan or sponsor obligations; or (ii)
the assets are returned to the sponsoring entity in order to reimburse it for employee benefits already paid.

&nbsp;&nbsp;&nbsp;&nbsp;• Actuarial gains and losses are changes in present value of defined benefit obligation resulting from:
(a) adjustments due to experience (the effects of differences between the actuarial assumptions adopted and what has actually occurred);
and (b) effects of changes in actuarial assumptions.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• Current service cost is the increase in the present value of the defined benefit obligation resulting
from employee service in the current period.

&nbsp;&nbsp;&nbsp;&nbsp;• The past service cost is the change in present value of defined benefit obligation for employee service
in prior periods resulting from a change in the plan or reductions in the number of employees covered.

Post-employment benefits are recognized in the income statement within "Interest expense and similar charges" and "Provisions (net)."

The defined benefit plans are recorded based on an actuarial study, and conducted by an external consultant, at the end of each year to therein be effective for the subsequent period.

***New Accounting Standards***

The new IFRS standards effective after January 1, 2025 are mentioned in our audited consolidated financial statements included in this annual report. For further information, see note 1 to our audited consolidated financial statements included elsewhere in this annual report.

All accounting policies and measurement bases with a material effect on the consolidated financial statements for 2025 were applied in the preparation of such financial statements.

**Results of Operations for the Years Ended December 31, 2025, 2024 and 2023**

**Executive Summary – Santander Brasil Results at a Glance**

***Total Income*** amounted to R$74,997 million in 2025, an increase of 1.7%, or R$1,239 million, in comparison with the year ended December 31, 2024, driven by an increase in net interest income and fee commissions.

***Consolidated Net Income*** totaled R$12,965 million in the year ended December 31, 2025, a decrease of 3.3% compared to the year ended December 31, 2024, mainly due to (i) an increase in other nonfinancial gains impacted by the joint venture transaction with the Pluxee Group in 2024; (ii) an increase in impairment losses on financial assets due to systematic increase in family indebtedness and system delinquency driven by a higher interest rate, and (iii) an increase in provisions, driven by higher labor contingencies.

***Loan Portfolio*** to customers amounted to R$602,040 million as of December 31, 2025, an increase of 0.4% compared to December 31, 2024, mainly due to an increase in our loan portfolio for consumer finance, SMEs (especially working capital) and individuals (especially credit cards and mortgages).

***Credit risk exposure*** amounted to R$778.9 billion as of December 31, 2025, an increase of 3.8% compared to December 31, 2024.

***Credit Quality:*** the impaired assets to credit risk exposure ratio was 6.3% for the year ended December 31, 2025, a 0.6 percentage points increase compared to the previous year.

***Coverage ratio*** was 83.2% in the year ended December 31, 2025, a 1.2 percentage points decrease compared to the year ended December 31, 2024.

***Our Basel Capital adequacy ratio*** was 15.4% in the year ended December 31, 2025, an increase of 1.1 percentage points compared to the year ended December 31, 2024.

***Deposits*** from customers and from the Brazilian Central Bank decreased by 3.1% reaching R$740 billion in 2025, mainly due to lower customer demand deposits especially in current accounts, reflecting a shift toward higher-yielding term instruments, both in Wholesale and Retail. Time deposits increased during the period, partially offsetting the reduction in demand balances. Deposits from credit institutions also decreased, mainly due to lower interbank time deposits and repurchase operations.

*Consolidated Net Income for the Year*

Our consolidated net income for the year ended December 31, 2025, was R$12,965 million, a decrease of R$449 million, or 3.3%, as compared to our consolidated net income of R$13,414 million for the year ended December 31, 2024, primarily due to (i) a decrease in other nonfinancial gains of R$1,700 million, or 88.9%, impacted by the joint venture transaction with the Pluxee Group in 2024; (ii) an increase in impairment losses on financial assets of R$1,056 million, or 3.7% due to systematic increase in family indebtedness and system delinquency driven by a higher interest rate, and (iii) an increase in provisions of R$384 million, or 8.3%, driven by higher labor contingencies.

Our consolidated net income for the year ended December 31, 2024, was R$13,414 million, an increase of R$3,915 million, or 41.2%, as compared to our consolidated net income of R$9,499 million for the year ended December 31, 2023, primarily due to (i) an increase in net interest income of R$9,795 million, or 20.9%, to R$56,679 million in the year ended December 31, 2024 from R$46,884 million in the year ended December 31, 2023, driven by the increase in net interest income in credit operations and better performance in market operations, despite the volatile macroeconomic environment; (ii) an increase in net fee income of R$1,565 million, or 10.0%, to R$17,205 million in the year ended December 31, 2024 from R$15,640 million in the year ended December 31, 2023, driven by the higher results in capitalization, insurance and cash management.

*[**Table of Contents**](#toc)*<br>

*Net Interest Income*

Net interest income for the year ended December 31, 2025, was R$57,634 million, an increase of R$956 million, or 1.7%, from R$56,679 million for the year ended December 31, 2024. This increase was mainly due to an increase in income from: (i) deposit products, especially time deposits and demand deposits in our individuals and SMEs businesses, and (ii) credit products, especially in our SMEs and consumer finance business, in each case driven by growth in volume in products such working capital, auto loans and mortgages. This was partially offset by the negative sensitivity to the increase of interest rates.

Average total earning assets in 2025 were R$1,110,376 million, an increase of 4.4% from R$1,063,823 million in 2024. The main driver of this change was an increase in the average amount of loans and advances to customers and loans and amounts due from credit institutions.

Net interest margin (net interest income divided by average earning assets) in 2025 was 5.2% compared to 5.3% in 2024, impacted by higher share of new businesses in collateralized products and focus on portfolios and segments with a lower credit risk, reflecting our strategy of seeking to increase net profitability.

Average total interest-bearing liabilities in 2025 were R$888,931 million, an increase of 4.7%, from R$849,299 million in 2024.

Finally, the net interest spread (the difference between interest on earning assets and the average cost of interest-bearing liabilities) was 2.7% in 2025, mainly due to a shift in our credit portfolio mix toward customers with a better risk profile, partially offset by a lower cost of funding in deposits.

Net interest income for the year ended December 31, 2024 was R$56,679 million, a 20.9% or R$9,795 million increase from R$46,884 million for the year ended December 31, 2023. This increase was mainly due to an increase in income from: (i) credit products, especially in our individuals and consumer finance businesses, driven by growth in volume in products such as cards, payroll, auto loan and mortgage, and (ii) better performance in market operations. This was partially offset by lower interest spreads, attributable to a shift in our portfolio mix toward customers with a better risk profile and focus on collateralized products.

Average total earning assets in 2024 were R$1,063,823 million, a 10.8% increase from R$959,769 million in 2023. The main driver of this change was an increase in the average amount of loans and advances to customers and financial assets measured at fair value (i.e., debt and equity instruments).

Net interest margin (net interest income divided by average earning assets) in 2024 was 5.3% compared to 4.9% in 2023, supported by the increase in the SELIC rate and a better credit products mix, following our strategy of increasing the share of individual segments.

Average total interest-bearing liabilities in 2024 were R$849,299 million, a 11.9% or R$90,386 million increase from R$758,913 million in 2023.

Finally, the net interest spread (the difference between interest on earning assets and the average cost of interest-bearing liabilities) was 3.3% in 2024, mainly due to a shift in our portfolio mix towards customers with a better risk profile.

*Income from equity instruments*

Income from equity instruments for the year ended December 31, 2025 totaled R$86 million, an increase of R$2 million from R$84 million for the year ended December 31, 2024.

Income from equity instruments for the year ended December 31, 2024 totaled R$84 million, a R$61 million increase from R$22 million for the year ended December 31, 2023*.*

*Income from Companies Accounted for by the Equity Method*

Income from companies accounted for by the equity method for the year ended December 31, 2025 was R$458 million, an increase of R$145 million from R$313 million for the year ended December 31, 2024, mainly due to an increase of R$58 million in the results of Pluxee, R$42 million in the results of Banco RCI and R$28 million in the results of Webmotors.

*[**Table of Contents**](#toc)*<br>

Income from companies accounted for by the equity method for the year ended December 31, 2024 was R$313 million, a R$74 million increase from R$239 million for the year ended December 31, 2023, mainly due to an increase of R$53 million in the results of Pluxee (which we acquired in 2024) and R$29 million in the results of Banco RCI.

*Net fee and commission income*

Net fee and commission income for the year ended December 31, 2025 was R$17,495 million, an increase of R$290 million, or 1.7%, compared to R$17,205 million for the year ended December 31, 2024. This increase was primarily driven by: (i) insurance and capitalization, supported by improved loan performance, particularly in consumer, and launch of new products; (ii) credit and debit cards, reflecting growth in transaction volumes and customer spending; and (iii) asset management and pension funds due to higher volumes of assets under management and of pension funds.

Net fees and commissions from credit and debit cards totaled R$4,508 million for the year ended December 31, 2025, an increase of 2.1% compared to the year ended December 31, 2024. This was primarily due to growth in transaction volumes and customer spending.

Net fees and commissions from asset management and pension funds totaled R$2,271 million for the year ended December 31, 2025, an increase of 3.3% compared to the year ended December 31, 2024. This was primarily due to higher volumes.

Net fees and commissions from insurance and capitalization totaled R$4,973 million for the year ended December 31, 2025, an increase of 4.9% compared to the year ended December 31, 2024. This was primarily due to improved loan performance and launch of new products.

Net fee and commission income for the year ended December 31, 2024 was R$17,205 million, a 10.0% or R$1,565 million increase compared to R$15,640 million for the year ended December 31, 2023. This increase was primarily attributable to: (i) credit and debit cards, mainly due to increases in our customer base, number of transactions and customer spending, (ii) insurance and capitalization, reflecting the improved performance in loans (especially in consumer), and (iii) asset management and pension funds.

Net fees and commissions from asset management and pension funds totaled R$2,199 million for the year ended December 31, 2024, an increase of 10.5% compared to the year ended December 31, 2023.

Net fees and commissions from insurance and capitalization totaled R$4,741 million for the year ended December 31, 2024, an increase of 10.2% compared to the year ended December 31, 2023.

Net fees and commissions from credit and debit cards totaled R$4,414 million for the year ended December 31, 2024, an increase of 24.2% compared to the year ended December 31, 2023.

The following table reflects the breakdown of net fee and commission income for the years ended December 31, 2025, 2024 and 2023:

*Gains (losses) on financial assets and liabilities (net) and exchange differences*

Gains on financial assets and liabilities (net) and exchange differences (net) for the year ended December 31, 2025 amounted to R$131 million, an increase of R$2 million compared to a gain of R$129 million for the year ended December 31, 2024. This variation is mainly due to financial assets measured at fair value through profit or loss, a R$641 million loss as of December 31, 2024 compared to a gain of R$7,890 million as of December 31, 2025.

Gains on financial assets and liabilities (net) and exchange differences (net) for the year ended December 31, 2024 amounted to R$129 million, a decrease of R$3,666 million compared to a gain of R$3,795 million for the year ended December 31, 2023. This variation is mainly due to lower gains with financial assets measured at fair value through profit or loss, of R$3,441 million as of December 31, 2023 compared to a loss of R$641 million as of December 31, 2024.

For further information, see notes 36 and 37 to our audited consolidated financial statements included elsewhere in this annual report.

*Other Operating Income/Expenses*

Other operating expenses for the year ended December 31, 2025, amounted to R$808 million, an increase of R$156 million compared to expenses of R$652 million for the year ended December 31, 2024, mainly due to higher operating expenses related to the growth of business activity and deposits portfolio.

The efficiency ratio, which we calculate as total administrative expenses divided by total income, increased to 27.9% in the year ended December 31, 2025, as compared to 27.7% for the year ended December 31, 2024. This increase of 0.2 percentage points in the ratio is primarily due to the growth of our costs outpacing the growth of our margin.

The efficiency ratio decreased to 27.7% in the year ended December 31, 2024, as compared to 29.7% for the year ended December 31, 2023. This decrease of 2.0 percentage points in the ratio is primarily due to higher growth in net income (driven by net interest income and net fee income) and an increase in costs driven by inflation.

*Other Nonfinancial Gains*

Other nonfinancial gains amounted to R$212 million during the year ended December 31, 2025, a decrease of R$1,700 million compared to R$1,912 million during the year ended December 31, 2024, mainly due to the one-off effect of the joint venture transaction with the Pluxee Group which occurred in 2024.

Other nonfinancial gains amounted to R$1,912 million during the year ended December 31, 2024, an increase of R$869 million compared to R$1,044 million during the year ended December 31, 2023, mainly due to the closing of the joint venture transaction with the Pluxee Group.

*Operating Income Before Tax* 

Operating income before tax for the year ended December 31, 2025 was R$16,729 million, a decrease of R$2,461 million, or 12.8%, as compared to R$19,190 million for the year ended December 31, 2024.

This was primarily due to the 2024 joint venture transaction with the Pluxee Group, higher impairment losses on financial assets reflecting a systematic increase in family indebtedness and delinquency levels, and increased provisions attributable to elevated labor contingencies.

*Income Taxes*

Income taxes expenses include income tax, social contribution, PIS and COFINS (which are social contributions due on certain income net of certain expenses).

Total income taxes amounted to R$3,764 million in the year ended December 31, 2025, a decrease of R$2,013 million, or 34.8%, in relation to R$5,776 million in the year ended December 31, 2024. This decrease in expense was mainly attributed to a decrease in operating income before tax to R$16,729 million in the year ended December 31, 2025, compared to R$19,190 million in the year ended December 31, 2024, primarily due to economic factors that directly impacted the increase in losses related to credit operations (IFRS 9). The lower earnings resulted in a smaller taxable base, leading to a proportional reduction in tax expense. Another event explaining the reduction in the income tax line relates to the increase in interest on equity to R$3,376 million in the year ended December 31, 2025, compared to R$2,589 million in the year ended December 31, 2024. Additionally, the effects of specific events recognized directly in the tax line remained stable compared to the prior year, with no material additional impacts on the variation in tax expense.

Total income taxes amounted to R$5,776 million in the year ended December 31, 2024, an increase of 138.4%, or R$3,354 million, in relation to R$2,423 million in the year ended December 31, 2023. This expense increase was mainly attributed to an increase in operating income before tax to R$19,190 million in the year ended December 31, 2024, from R$11,922 million in the year ended December 31, 2023, which was primarily due to our operational performance throughout the year. The higher earnings resulted in a larger taxable base, leading to a proportional increase in tax expense. Additionally, the effects of specific events recognized directly in the tax line remained stable compared to the prior year, with no material additional impacts on the variation in tax expense.

**5B. Liquidity and Capital Resources** 

Our asset and liability management strategy is set by the asset and liability committee, which operates under strict guidelines and procedures established by the Santander Group. The asset and liability committee establishes, among other policies, our funding strategy, and the target positioning with respect to structural balance sheet risk.

*[**Table of Contents**](#toc)*<br>

Pursuant to the Santander Group's model, all subsidiaries must be self-funded in terms of liquidity and capital. In addition, our general asset and liability management policy is to maintain a close match of maturity, interest rate and currency exposures. Subject to our internal risk management policies we aim to maintain adequate liquidity to meet our present and future financial obligations and to capitalize on business and market opportunities as they arise.

Most of our liquidity is raised in the local market and we maintain a portfolio of high-quality public bonds for liquidity management. Legal reserve requirements consume a significant amount of funding in Brazil, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Compulsory Reserve Requirements."

Due to our diversified sources of funding, which include a large client deposit base in the local market and a large number of correspondent banks with long-standing relationships, historically we have not experienced liquidity problems. In our opinion, our current levels of liquidity are sufficient for our present requirements.

See also "Item 4. Information on the Company—B. Business Overview—Selected Statistical Information."

**Liquidity and Funding**

In addition to a minimum liquidity level that meets our stress scenarios, we monitor concentration of funding ratios and the short term (LCR) and long term (Net Stable Funding Ratio) liquidity metrics, which aims to guarantee a stable funding profile. We control, manage and review our liquidity analyzing current and expected levels of liquidity, structuring the sources of financing to achieve an optimal diversification in terms of maturities, instruments, currencies, markets, as well as setting forth contingency plans. The objective is to ensure that we have sufficient liquidity to honor our commitments in light of market conditions, our institutional needs and market opportunities.

Due to our stable and diversified funding sources, which include a large base of customer deposits as detailed below, we have historically had no liquidity deficiencies.

As part of our liquidity management, we have a formal plan with measures to be taken in the event of a systemic liquidity crisis and/or for liquidity concerns arising from possible reputational risk. Our liquidity contingency plan contains defined thresholds, preventive measures and actions to be taken when a liquidity deficiency occurs and our reserves fall below certain levels.

The following resources and strategies may be used as sources of funding: (i) increase of customer deposits; (ii) securities issuances; (iii) repurchase agreements; (iv) a review of transfer pricing practices; and (v) establishment of more restrictive credit policies.

For further information, see notes 16, 17, 18, 19 and 20 to our audited consolidated financial statements included elsewhere in this annual report.

The following tables present the composition of our consolidated funding at the dates indicated.

(1) Refers primarily to repurchase agreements backed by debentures.

(2) This includes transactions with credit institutions in connection with export and import financing lines,
BNDES and FINAME on-lending and abroad on other credit lines abroad.

(3) In the year ended December 31, 2023, we revised the definition of marketable debt securities to include
the line items "Financial liabilities measured at fair value in income held for trading" and "Financial liabilities
at amortized cost," instead of only including "Financial liabilities at amortized cost." The amounts presented as of
December 31, 2025, 2024 and 2023 reflect this change.

***Deposits***

***Customer Deposits***

Our balance of customer deposits was R$593.3 billion on December 31, 2025, R$605.1 billion on December 31, 2024, and R$583.2 billion on December 31, 2023, representing 63.9%, 65.3% and 68.5% of our total funding, respectively.

*Current Accounts*

Our balance of current accounts was R$31.9 billion on December 31, 2025, R$41.3 billion on December 31, 2024 and R$36.6 billion on December 31, 2023, representing 4.3%, 5.4% and 5.2% of total deposits, respectively.

*[**Table of Contents**](#toc)*<br>

*Savings Accounts*

Our balance of savings accounts was R$53.2 billion on December 31, 2025, R$57.4 billion on December 31, 2024, and R$58.1 billion on December 31, 2023, representing 7.2%, 7.5% and 8.3% of total deposits, respectively.

*Customer Time Deposits*

Our balance of customer time deposits was R$431.7 billion on December 31, 2025, R$425.3 billion on December 31, 2024, and R$390.5 billion on December 31, 2023, representing 58.3%, 55.7% and 55.6% of total deposits, respectively.

*Customer Repurchase Agreements*

We maintain a portfolio of Brazilian public and private sector debt instruments used to obtain overnight funds from other financial institutions or investment funds by selling such securities and simultaneously agreeing to repurchase them. Due to the short-term (overnight) nature of this funding source, such transactions are volatile and composed, generally, of Brazilian public securities and of repurchase agreements linked to debentures. Securities sold under repurchase agreements decreased to R$76.6 billion on December 31, 2025, from R$81.1 billion on December 31, 2024, and R$98.0 billion on December 31, 2023, representing 10.3%, 10.6% and 14.0% of total deposits, respectively.

***Deposits from Credit Institutions***

Our balance of deposits from credit institutions was R$146.9 billion on December 31, 2025, R$158.6 billion on December 31, 2024 and R$118.5 billion on December 31, 2023, representing 19.8%, 20.8% and 16.9% of total deposits, respectively.

Our balance of deposits includes mainly borrowings and domestic on lendings:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Borrowings. We have relationships with banks all over the world, providing credit lines as foreign currency-linked
(either to the U.S. dollar or to a basket of foreign currencies). We apply the proceeds from these transactions mainly to U.S. dollar-linked
lending operations and in particular to trade finance operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Domestic Onlendings. We borrow from public institutions, mainly BNDES and FINAME, for which we act as
a financial agent. Funding from these sources in Brazil represents a method of providing long-term loans with attractive average interest
rates to certain sectors of the economy. Loans from these funds are allocated by BNDES through banks to specific sectors targeted for
economic development. This type of lending is known as "repassing" or "onlending." Because the repassed funds
are generally matched and/or funded by loans from a federal government agency, we take no interest rate or maturity mismatch risk nor
charge interest at a fixed margin over the cost of funds. We, however, retain the commercial credit risk of the borrower and therefore
have discretion in the lending decision and application of the credit criteria. This type of funding is not affected by compulsory deposit
requirements. The onlending is generally secured or guaranteed, although this is not required by the terms of the onlending.

***Other Funding***

*Liabilities arising from securities*

Our balance of liabilities arising from securities was R$159.9 billion on December 31, 2025, R$139.7 billion on December 31, 2024, and R$130.4 billion on December 31, 2023, representing 17.2%, 15.1%, and 15.3% of our total funding, respectively.

Agribusiness credit notes (*Letra de Crédito do Agronegócio*), which are credit notes that are freely negotiable and represent an unconditional promise of payment in cash, are issued exclusively by financial institutions and related to credit rights originated from transactions conducted between rural producers and their cooperatives and agents of the agribusiness production chain and the exchange acceptances, reached R$38.7 billion on December 31, 2025, R$32.4 billion on December 31, 2024 and R$36.4 billion on December 31, 2023.

Financial bills (*Letras Financeiras*) are a funding alternative available to banks that can be characterized as senior or eligible to compose the regulatory capital, pursuant to CMN Resolution No. 5,007, of March 24, 2022, with a minimum term of 24 months and minimum amounts of R$300,000 for subordinated transactions and R$50,000 for senior transactions. Our balance of treasury bills totaled R$38.2 billion on December 31, 2025, a 56.0% increase from R$24.5 billion on December 31, 2024.

*[**Table of Contents**](#toc)*<br>

Real estate credit notes (*Letras de Crédito Imobiliário*) increased by 3.2%, from R$62.9 billion on December 31, 2024, to R$64.9 billion on December 31, 2025.

We undertake issuances of securities, including under our Global Medium Term Notes Program. Our balance of bonds and other securities was R$18.1 billion on December 31, 2025, and R$19.9 billion on December 31, 2024. This change was principally due to favorable market conditions.

*Debt Instruments Eligible to Compose Tier 1 and Tier 2 Capital*

On November 5, 2018, our board of directors approved the issuance, through our Cayman Islands branch, of debt instruments to form part of our Tier 1 and Tier 2 regulatory capital in the aggregate amount of U.S.$2.5 billion, pursuant to an offering made to non-U.S. Persons under Regulation S of the U.S. Securities Act of 1933, as amended, or the "Notes Offering." Our Notes Offering was structured as follows: (i) U.S.$1.25 billion indexed 7.25% per year with no maturity (perpetual) and interest paid semiannually; and (ii) U.S.$1.25 billion indexed 6.125% per year maturing in November 2028 and interest paid semiannually. These issuances were made through our Cayman Islands branch and as a result they do not generate liability for income tax at source. In addition, our board of directors also approved the redemption of debt instruments issued to form part of our Tier 1 and Tier 2 regulatory capital, as set out in the board's resolution of January 14, 2014. The proceeds from the Notes Offering were used to fund this redemption. On December 18, 2018, the Brazilian Central Bank authorized the transactions contemplated in the Notes Offering and the redemption, which were completed on January 29, 2019.

In November and December 2021, Santander Brasil issued financial bills with a subordination clause, to be used to compose our Tier 2 regulatory capital, in the total amount of R$5.5 billion. The financial bills have a term of ten years, and redemption and repurchase options in accordance with the applicable regulations. The financial bills had an estimated impact of 92 basis points on our Tier 2 regulatory capital.

In October and November 2023, Santander Brasil exercised its option to repurchase the Tier 2 debt instruments issued in 2018 in the amount of U.S.$1.25 billion. In their place to compose our Tier 2 regulatory capital, Santander Brasil issued financial bills with a subordination clause in the total amount of R$6.0 billion. These new financial bills have a term of 10 years, and redemption and repurchase options in accordance with the applicable regulations.

On November 8, 2024, Santander Brasil also exercised its option to repurchase certain Tier 1 debt instruments issued in 2018 in the amount of U.S.$1.25 billion. In their place to comprise our Tier 1 regulatory capital, Santander Brasil issued subordinated financial bills in the total amount of R$7.6 billion. These new financial bills are perpetual with a repurchase clause exercisable as from five years of their issuance, in accordance with the applicable regulations.

Furthermore, on December 4, 2025, Santander Brasil issued financial bills with a Tier 2 subordination clause in the total amount of R$2.4 billion. These new financial bills have a term of 10 years, semiannual coupon payments as well as redemption and repurchase options in accordance with the applicable regulations.

As of December 2025, the balance for both Tier 1 and Tier 2 debt instruments was R$28.1 billion, compared to R$23.1 billion as of December 31, 2024.

***Capital Management***

Our capital management is based on conservative principles and continuous monitoring of the items that affect our solvency level. We are required to comply with Brazilian capital adequacy regulations under Brazilian Central Bank rules. In October 2013, the new regulations implementing the capital and the regulatory capital requirements of the Basel Committee on Banking Supervision (Basel III) came into effect in Brazil, including the recently enacted Resolution No. 229, which reformed the prudential rules applicable to capital requirements associated with credit risk under the standardized approach (RWACPAD). For additional information regarding minimum regulatory level and other Basel III requirements, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision— Capital Adequacy and Leverage—Basel—Basel III" and note 30, Operational Ratios, to our audited consolidated financial statements included elsewhere in this annual report.

CMN regulations establish conservative capital and countercyclical buffers for Brazilian financial institutions and determine the minimum percentages applicable as well as which sanctions and limitations will apply in case of noncompliance with such additional requirements. See "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Principal Limitations and Obligations of Financial Institutions."

*[**Table of Contents**](#toc)*<br>

**Capital Expenditures**

See "Item 4. Information on the Company—A. History and Development of the Company—Capital Expenditures and Divestitures."

**Off-Balance Sheet Arrangements**

We have entered, in the normal course of business, into several types of off-balance sheet arrangements, including lines and letters of credit and financial guarantees. For more information, see note 43 to our audited consolidated financial statements included elsewhere in this annual report.

*Lending-Related Financial Instruments and Guarantees*

We use lines and letters of credit and financial guarantee instruments to meet the financing needs of our customers. The contractual amount of these financial instruments represents represent the maximum possible credit risk should the counterparty draw down the commitment or we fulfill our obligation under the guarantee, and the counterparty subsequently fails to perform according to the terms of the contract. Most commitments and guarantees expire without the counterparty drawing on the credit line or a default occurring. As a result, the total contractual amount of these instruments does not represent our future credit exposure or funding requirements. Further, certain commitments, primarily related to consumer financing are cancelable, upon notice, at our option.

The "maximum potential amount of future payments" represents a notional amount potentially lost if a total default by the guaranteed parties occurred, without considering possible recoveries from collateral held or pledged, or those under recourse provisions. There is no relationship between these amounts and probable losses on these guarantees. In fact, the maximum potential amount of future payments significantly exceeds inherent losses.

For further information, see note 43 to our audited consolidated financial statements included elsewhere in this annual report.

**Contractual Obligations**

Our contractual obligations as of December 31, 2025 are summarized as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  | **As of December 31, 2025** | **As of December 31, 2025** | **As of December 31, 2025** | **As of December 31, 2025** | **As of December 31, 2025** |

(1) In the year ended December 31, 2023, we revised the definition of marketable debt securities to include
the line items "Financial liabilities measured at fair value in income held for trading" and "Financial liabilities
at amortized cost," instead of only including "Financial liabilities at amortized cost." The amounts presented as of
December 31, 2025, 2024 and 2023 reflect this change.

(2) The table above excludes the notional and any interest payments relating to our perpetual Tier I bonds
which interests are discretionary as described in "Item 5. Operating And Financial Review And Prospects—A. Operating Results."

(3) Calculated for all Deposits from credit institutions, Customer Deposits, Marketable debt securities,
Subordinated liabilities and Debt Instruments Eligible to Compose Capital (Tier II) assuming a constant interest rate based on data as
of December 31, 2024 over time for all maturities, and those obligations with maturities of more than five years have an average life
of ten years.

*[**Table of Contents**](#toc)*<br>

The above table does not reflect amounts payable on derivative contracts as they are dependent on changes in financial markets. The net fair value position of our derivative contracts as of December 31, 2025 reflected assets of ‎R$5,796 million, compared to assets of ‎R$796 million as of December 31, 2024.

In addition, we lease several properties under standard lease contracts, which can be cancelled or renewed at our option and include escalation clauses. The total future minimum payments of non-cancelable operating leases as of December 31, 2025 was R$3,595 million. From this total, R$1,531 million matures in up to one year, R$2,010 million matures from one year to up to five years and R$54 million matures after five years. We have no contracts with indeterminate maturities.

**5C. Research and Development, Patents and Licenses, etc.**

We do not have any policy or significant project involving research and development, and we do not own patents or patents licenses, bearing in mind that we only have licenses involving trademarks.

**5D. Trend Information**

The following list sets forth, in our view, the most important trends, uncertainties and events that are reasonably likely to continue to have a material effect on our revenues, income from continuing operations, profitability, liquidity and capital resources, or that may cause reported financial information to be not necessarily indicative of future operating results or financial condition:

&nbsp;&nbsp;&nbsp;&nbsp;• economic and political conditions in Brazil, including the impact of the current international economic
environment and the macroeconomic conditions in Brazil, and the policies of the new Brazilian administration that will take office following
the presidential and other elections to be held in October 2026, may adversely affect the performance of the Brazilian economy. As a result,
our credit portfolio, which is focused on Brazil, may not grow or could decrease and our provisions for loan losses increase;

&nbsp;&nbsp;&nbsp;&nbsp;• a global economic downturn as a result of pandemics, epidemics or outbreaks of infectious diseases,
or instability or conflicts (including the ongoing war between Russia and Ukraine and uncertainties following the ceasefire agreement
in the Middle East, or the general economic and business conditions in Brazil, Latin America and globally), can have an adverse effect
on the global market and economy, including Brazil. It may decrease the interest of investors in Brazilian assets, in addition to making
it difficult for us to access the capital markets and finance our operations, including on acceptable terms;

&nbsp;&nbsp;&nbsp;&nbsp;• uncertainties arising from the Brazilian presidential and other elections scheduled for October 2026,
increased volatility in economic indicators and deceleration in growth rates may negatively affect our strategic plan, with impacts on
our profitability, asset quality, portfolio expansion and financing conditions;

&nbsp;&nbsp;&nbsp;&nbsp;• exposure to various types of inflation and interest rate risks, and the Brazilian government's
efforts to control inflation and interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;• continued market volatility and instability that could affect our revenues;

&nbsp;&nbsp;&nbsp;&nbsp;• extensive regulation by the Brazilian government and the Brazilian Central Bank, among others, which
could affect our margins and/or growth in lending activities;

&nbsp;&nbsp;&nbsp;&nbsp;• regulatory capital changes toward more restrictive rules as a response to any potential financial crisis
or general macroeconomic conditions;

&nbsp;&nbsp;&nbsp;&nbsp;• decreased liquidity in domestic capital markets;

&nbsp;&nbsp;&nbsp;&nbsp;• changes in taxes or other fiscal assessments that could decrease our profitability;

&nbsp;&nbsp;&nbsp;&nbsp;• exchange rate volatility and exchange rate controls that could have an adverse impact on international
investors;

&nbsp;&nbsp;&nbsp;&nbsp;• our ability to protect ourselves against cybersecurity risks;

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• the effects of climate change, including transition risks, physical risks and other risks that could
adversely affect us; and

&nbsp;&nbsp;&nbsp;&nbsp;• our dependence on the proper functioning of information technology systems.

Conversely, a recovery in the Brazilian economy by means of economic reforms (e.g., an overhaul in the income tax structure) could have a positive effect on the Brazilian economy and, therefore, on our business.

For more information, see "Item 3. Key Information—D. Risk Factors" where we present the risks we face in our business that may affect our commercial activities, operating results or liquidity.

**5E. Critical Accounting Estimates**

Our financial statements are presented in IFRS as issued by the IASB. For summary information about critical judgments, assumptions and estimation uncertainties in applying accounting policies that have the most significant effect on the amounts recognized in the financial statements, see "—A. Operating Results—Principal Factors Affecting Our Financial Condition and Results of Operations—Critical Accounting Policies" and notes 1(c) and 2 to our audited consolidated financial statements included elsewhere in this annual report.

**ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES** 

**6A. Board of Directors and Board of Executive Officers**

Pursuant to our By-Laws, we are managed by a board of directors (*conselho de administração*) and a board of executive officers (*diretoria executiva*). The board of directors is our supervisory board as set out in our By-Laws and in applicable legislation. Our board of executive officers is responsible for our day-to-day management. Our board of directors comprises a minimum of five members and a maximum of twelve members, of which at least 20.0% must be independent members. The board of directors has a chairman and a vice-chairman, each elected at the general shareholders' meeting by majority vote.

Our board of executive officers comprises a minimum of two members and a maximum of 75 members, one of them being appointed as the Chief Executive Officer, and the others may be appointed as senior vice president executive officers, vice president executive officers, investor relations officers, executive officers and officers without specific designations. Some of our executive officers are also members of the boards of executive officers and/or boards of directors of our subsidiaries.

Our current Chief Financial Officer and Investor Relations Officer, Mr. Gustavo Alejo Viviani, will step down from his position at the end of April 2026 and will be succeeded by Mr. Carlos Muñiz González-Blanch, who will assume the role following the completion of the established internal governance process.

Pursuant to Brazilian law, the election of each member of the board of directors and board of executive officers must be approved by the Brazilian Central Bank.

The following table presents the names, positions and dates of birth of the current members of our board of directors and board of executive officers:

*[**Table of Contents**](#toc)*<br>

***Deferral Program***

Our deferral program is available to our Statutory Officers, Officers in positions of management and certain other eligible employees. As part of the deferral program, we defer between 40% and 60% of the variable compensation of an employee over a period of three to five years, depending on the employee's level of responsibility. The program aims to (i) align the program with the principles of the Financial Stability Board, or "FSB," agreed upon at the G20; (ii) align our interests with those of the plan's participants (to achieve sustainable and recurring growth and profitability of our businesses and to recognize the participants' contributions); (iii) allow the retention of participants; and (iv) improve our performance and protect the interests of shareholders via a long-term commitment.

Pursuant to Brazilian law, variable compensation is required to be compatible with the financial institution's own risk management policies. At least 50% of variable compensation must be paid in stock or stock-based instruments and at least 40% of variable compensation must be deferred for future payment by at least three years. These rules became effective as from January 1, 2012. The following table summarizes the rules of payment of variable compensation taking as an example the exercise ended on December 31, 2025.

The deferral percentage will also depend on the level of variable compensation received in the year and function held within Santander Brasil, with the abovementioned criteria applied as minimum. For our senior leadership, the deferral period can reach up to five years.

In addition, pursuant to Brazilian law, all deferral plans are subject to the application of malus/clawback, which means that our board of directors, upon the recommendation of the Compensation Committee and after the evaluation of the Malus/Clawback Committee (which is responsible for advising our compensation committee on the application of the malus/clawback to compensation, among other matters), may reduce in up to 100% the amount due to each participant in certain cases previously approved by our internal governance bodies.

On November 29, 2023, our board of directors approved our clawback policy, an English translation of which is attached to this annual report as Exhibit 97.1. This policy includes rules relating to the clawback of incentive-based compensation to subject executives, in the event of a restatement of our financial statements as a result of material failure to comply with financial reporting requirements under applicable U.S. federal securities laws. This policy is intended to comply with the requirements of Section 10D of the Exchange Act and New York Stock Exchange rules.

*2019-2021 Deferral Programs*

Since 2019, the rule for the Collective Unidentified was changed to "Other Employees," which includes superintendents and other employees with variable compensation above a minimum established value, and they are also eligible to receive a specific deferral model, applicable according to the function and the level of the variable compensation. Deferred compensation will be paid 50% in cash, and 50% in units (ticker: SANB11). Each deferral program applies solely to its corresponding performance year and is governed by the policies and regulations in effect at the time of its approval.

*2022 Deferral Program*

Since 2022, our deferral program was revised as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• *Collective Identified*: Applicable to statutory officers and executives who oversee significant
risks in Santander Brasil and are in charge of the control areas. Deferred compensation will be paid 50% in cash, indexed to 100% of the
CDI Rate, 50% in units (ticker: SANB11).

&nbsp;&nbsp;&nbsp;&nbsp;• *Other Employees*: Individuals with variable compensation above a minimum established value are

***Long-Term Incentive Programs***

Our long-term incentive plans are established in line with our business strategy. Each plan has a specific set of indicators and operating rules, and grants within our plans may be either global (i.e., based on shares in Santander Spain) or local (i.e., based on shares in Santander Brasil). The grants and payments under each of our long-term incentive plans must be approved by our governance structures in place at the time of approval, including the people and culture department and the finance department, and must comply with applicable laws and regulations governing such plans. Executive officers and executives in key positions are eligible to participate in these plans, which last three years, and foster our executive officers and executives' commitment to our long-term results. Members of the Board of Directors can only participate if they are Executive Officers.

Our long-term programs are divided into local and global plans. Each plan has specific performance indicators and conditions to best maintain the participant's employment relationship until the payment date in order to be entitled to the receipt. Payments are calculated based on the percentage of achievement of the indicators applied on the reference value (target).

*Local Long-Term Incentive Program*

We have retention plans for key positions and payments of these plans can be made in cash or in units (ticker: SANB11), and are subject to the application of the malus/clawback clauses, which may result in a reduction or full cancellation in the number of shares to be delivered in cases of failure to comply with internal rules and exposure to excessive risks.

Until 2024, the settlement value of units was calculated based the average price of the last 50 trading sessions immediately prior to the month of payment under the plan. This provision was changed in 2025 (and onwards) to the average price of the last 30 trading sessions immediately prior to the month of payment. At the end of the vesting period, the resulting shares are delivered with a one-year restriction, and this payment is still subject to the application of the malus/clawback clauses, which may reduce or cancel the shares to be delivered in cases of noncompliance with internal rules and exposure to excessive risks.

*[**Table of Contents**](#toc)*<br>

For the year ended December 31, 2025, we incurred expenses of R$6.8 million, with respect to our local long-term incentive program, compared to total expenses of R$4.3 million in the year ended December 31, 2024.

*Global Long-Term Incentive Program*

We currently have three global plans launched in 2020, 2021, 2022, 2023 and 2024. Eligible executives had an incentive target set in *reais*. Payments according to the achievement of performance indicators are made in shares and options after a minimum deferral period of three years, with equivalent settlement in *reais*.

For the year ended December 31, 2025, we incurred expenses of R$4.3 million in connection with our global long-term incentive program, compared to total expenses of R$5.1 million in 2024.

**Contract Termination**

Employment contracts are entered into for an undefined term. The termination of the employment relationship for nonfulfillment of obligations or voluntarily does not entitle executives to any financial compensation.

**Pension and Retirement Benefits**

Members of our board of directors and our executive officers may enroll in our retirement plan, SBPrev, while they are affiliated with Santander Brasil.

In 2024, we adopted the Santander Sócios pension plan, exclusive to Santander Brasil members. For further information, please see "—D. Employees."

**6C. Board Practices**

Our shareholders elect members of our Board of Directors at the annual general shareholders' meeting for two-year terms (members may be reelected). The Board of Directors appoints our executive officers for two-year terms (members may be reelected).

The current members of the Board of Directors were elected at the ordinary shareholders' meeting held on April 25, 2025 and at the extraordinary shareholders' meeting held on July 4, 2025, to serve until the ordinary shareholders' meeting to be held in 2027. The current Executive Officers were elected at Board of Directors meetings held on April 28, 2025, September 1, 2025 and November 14, 2025, for terms of office until the first Board of Directors meeting that occurs after the ordinary shareholders' meeting of 2027.

**Fiscal Council**

According to Brazilian Corporate Law, the adoption of a permanent fiscal council, as a publicly held company, is voluntary. Our By-Laws provide for a nonpermanent fiscal council, which can be installed at the request of shareholders, representing at least one percent of the voting shares or two percent of the nonvoting shares. The fiscal council was not installed at any of our shareholders' meeting held during 2025.

The fiscal council is an independent body elected by shareholders to supervise the activities of managers and independent auditors. The responsibilities of the fiscal council are established by Brazilian Corporate Law and include oversight of management's compliance with laws and By-Laws, the issuance of a report on the company's annual and quarterly reports, certain matters submitted for shareholders' approval, calling of shareholders' meetings in some cases and reporting on specific matters arising at those meetings.

We provide a competitive benefits package, which contributes to the engagement, attraction and retention of our employees. To ensure competitiveness, we compare our annual benefit package to market practices and trends. Policies are developed and offered based on the needs of our employees. We also have a policy of providing continuous training to our employees, allowing them to hone their skills and create a more effective team, committed to the values of the group.

We have a profit sharing plan with our employees based on predetermined goals for our annual operating and financial results. As a result, if we meet or exceed certain goals, our employees can share in our financial performance. See "—B. Compensation."

We offer our employees a private pension plan structured as a defined contribution plan, with contributions made by both employees and us. The plans provide benefits related to retirement, disability and death, and also allow for continued participation with self-funded contributions (self-sponsorship), deferred vested benefits, portability to another pension plan, and withdrawal of accumulated balances, in accordance with the rules and provisions set forth in each plan's governing regulations:

&nbsp;&nbsp;&nbsp;&nbsp;• *Santander Previ* —the Santander Previ pension plan has been closed to new enrollments since
July 2018. As of December 31, 2025, the plan had 19,794 participants, with total assets under management of approximately R$5.78 billion.

&nbsp;&nbsp;&nbsp;&nbsp;• *SBPrev* — SBPrev is a pension plan offered since 2018 to newly hired employees or eligible
employees who elect to participate. The plan is administered by Zurich Santander Brasil Seguros e Previdência. As of December 31,
2025, the SBPrev plan had 7,794 registered participants, with total assets under management of R$380 million.

&nbsp;&nbsp;&nbsp;&nbsp;• *Santander Sócios* —in January 2024, the Santander Sócios Program was implemented
for the executive officers of Santander Brasil, providing a supplementary pension benefit covering retirement, disability and death.

For further details about our pension plans, see note 21 to our audited consolidated financial statements included elsewhere in this annual report.

The *Sindicato dos Bancários* (Brazilian Bank Employees' Union), the union of banking employees in Brazil, represents the majority of our employees in potential labor-related matters involving banking employees and/or the banking union, with negotiations conducted by the *Federação Nacional dos Bancos* (National Federation of Banks), or FENABAN, the employers' association. Every two years, typically in September, Brazilian banks engage in a collective bargaining process aimed at reviewing salary structures. During this process, the Brazilian Bank Employees' Union negotiates with FENABAN adjustments to fixed salaries and employee benefits in accordance with the Brazilian Banking Sector Collective Bargaining Agreement. Negotiations covering the period from 2024 to 2026 have been concluded, and the agreed compensation levels are consistent with market practices. In 2026, the collective bargaining process for the next banking sector collective bargaining agreement is expected to commence, in accordance with the sector's regular calendar and with the participation of representative trade unions. Since the acquisition of our predecessor banks by our indirect shareholder Santander Spain, we have not experienced material losses or disruptions as a result of strikes and management believes it maintains constructive relationships with its employees.

**7B. Related Party Transactions**

We have a related party transactions policy, which is intended to ensure that all transactions covered by the policy are conducted in our interest and that any related party transactions are conducted on an arm's-length basis on terms substantially similar to those of comparable transactions in the market. The policy defines related transactions as those occurring between us and our shareholders, our subsidiaries, our employees, directors and officers, as well as our subsidiaries' employees, directors and officers. The policy defines the power to approve certain transactions as resting with the board of directors. Additionally, related party transactions are included in the regular auditing program developed by our internal audit.

We currently engage in and expect from time to time in the future to engage in financial and commercial transactions with our subsidiaries and affiliates and those of the Santander Group. We have credit lines outstanding with certain of our affiliates within the Santander Group. As of December 31, 2025, borrowings and deposits from the Santander Group did not account for any of our total funding. In addition, from time to time, we enter into certain transactions with the Santander Group and other related parties for the provision of consulting, advisory and advertising services. Such transactions are conducted on an arm's-length basis, based on terms that would have been applied for transactions with third parties.

The transactions and remuneration of services with related parties are made in the ordinary course of business on an arms' length basis under similar conditions, including interest rates, terms and guarantees, and involve no greater risk than transactions with unrelated parties carried out in the ordinary course and have no other disadvantages. The following discussion describes all of our material related party transactions.

For further information, see note 45 to our audited consolidated financial statements included elsewhere in this annual

report.

**Information** **Technology Platform** 

We have entered into agreements with some affiliates of the Santander Group for the outsourcing of certain products and services relating to our information technology platform, including software development and maintenance and cybersecurity.

In August 2025, the hardware infrastructure services were migrated to Santander Service Digital S.L, as well as the resources that operate this service.

We believe these services are provided on an arm's-length basis with terms substantially similar to those available from other providers in the market. For further information see "Item 4. Information on the Company—B. Business Overview—Technology and Infrastructure."

**Procurement Services**

We have entered into agreements with Aquanima Brasil Ltda., or "Aquanima," an affiliate within the Santander Group, which provides procurement services to Santander Brasil and its affiliates. We procure solutions in trade negotiations, tactical and strategic purchasing, online procurement, supplier management, outsourcing, consulting, and vendor risk assessment from Aquanima. Our relationship with Aquanima include the joint purchases of materials and services between different customers and other economic groups, which we believe allow for greater efficiency in price negotiations and rationalization of services, as well as the engagement of real estate management services in 2021. We paid Aquanima R$18 million in 2025, R$36 million in 2024 and R$42 million in 2023 for the services rendered in those years.

**Legal Proceedings**

We are a party to lawsuits and administrative proceedings incidental to the normal course of our business. The main categories of lawsuits and administrative proceedings to which we are subject include:

&nbsp;&nbsp;&nbsp;&nbsp;• administrative and judicial actions relating to taxes;

&nbsp;&nbsp;&nbsp;&nbsp;• administrative and indemnification suits for damages related to consumer rights, especially in relation
to credit cards, checking accounts and loan disputes;

&nbsp;&nbsp;&nbsp;&nbsp;• lawsuits involving disputes related to contracts and instruments to which we are a party, including
claims related to breach of contracts;

&nbsp;&nbsp;&nbsp;&nbsp;• civil lawsuits mainly from depositors and civil associations, including individual lawsuits and class
actions, challenging monetary adjustments determined by government economic plans instituted to combat inflation during the 1980s and
1990s;

&nbsp;&nbsp;&nbsp;&nbsp;• class actions involving agreements and settlement of debts with the public sector; and

&nbsp;&nbsp;&nbsp;&nbsp;• suits brought by employees, former employees, associations and unions relating to alleged labor rights
violations.

In accordance with IAS 37 – Provisions, Contingent Liabilities and Contingent Assets, we record provisions for judicial proceedings in which we assess the risk of loss to be probable and we do not record provisions when the risk of loss is possible or remote. In cases where there is ongoing litigation, we record a provision for our estimate of the probable loss based on historical data for similar claims. In addition, we record provisions (i) on a case-by-case basis based on the analysis and legal opinion of internal and external counsel or (ii) by considering the historical average amount of loss of such category of lawsuits. Due to the established provisions and the legal opinions provided by our counsel, we believe that any liabilities related to lawsuits or proceedings to which we are a party, both individually and in aggregate, will not have a material adverse effect on our financial condition or results of operations.

As of December 31, 2025, our judicial and administrative proceedings classified as probable loss risk (tax, labor and civil) and legal obligation amounted to R$12,083.0 million and have been provisioned. We believe that we have made adequate provisions related to the costs anticipated to be incurred in connection with our judicial and administrative proceedings. As of December 31, 2025, our judicial and administrative proceedings classified as possible loss risk (tax, labor and civil) amounted to approximately R$41,237.1 million.

***Tax Litigation***

We are a party to several tax-related lawsuits and judicial and administrative proceedings.

As of December 31, 2025, our tax proceedings with a probable risk of loss amounted to approximately R$5,132.3 million, which was fully provisioned, and our tax proceedings with a possible risk of loss amounted to approximately R$37,518.1 million.

Our primary legal and administrative proceedings classified with a probable loss risk assessment are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• *ISS Litigation*: Certain municipalities levy ISS on certain revenues derived from transactions
not usually classified as the rendering of services. We have filed suit against the payment of such taxes. As of December 31, 2025,
the total amount involved in these proceedings totaled R$334.7 million, which was fully provisioned.

&nbsp;&nbsp;&nbsp;&nbsp;• *Social Security Litigation*: We are involved in administrative and judicial proceedings relating
to the collection of income tax on social security and education allowance contributions, as we believe that these benefits do not constitute
taxable wages. As of December 31, 2025, amounts related to these proceedings totaled R$167.5 million, which are fully provisioned.

&nbsp;&nbsp;&nbsp;&nbsp;• *Banking Transactions Tax Litigation*: In May 2003, the Brazilian Federal Revenue Service
 issued a tax assessment against Santander Distribuidora de Títulos e Valores Mobiliários Ltda., or "Santander
 DTVM" and another tax assessment against Santander Brasil. The tax assessments refer to the collection of the compulsory
 contribution over financial transaction (*Contribuição Provisória sobre Movimentação Financeira*), or the "CPMF," on transactions conducted by Santander
DTVM in the cash management of its customers' funds and clearance services provided by Santander Brasil to Santander DTVM in 2000,
2001 and 2002. Based on our tax advisors' opinion, the procedures adopted by Santander DTVM were correct. The administrative discussion
ended unfavorably for both companies. On July 3, 2015, Santander Brasil and F1rst Tecnologia e Inovação Ltda. (the current
name of Santander DTVM) filed a lawsuit requesting the cancellation of both tax assessments. The lawsuit was rejected. We appealed this
decision. On December 8, 2020, our appeals were rejected. We filed an appeal for clarification against this decision, which was rejected.
As a result, new appeals to the superior courts, including to the Brazilian High Court of Justice (*Superior Tribunal de Justiça*),
or "STJ," and the STF have been filed. This case is in the scope of the Comprehensive Transaction Programme (Programa de Transação
Integral) established by the Ministry of Finance. The amounts paid as established by the Comprehensive Transaction Program were fully
provisioned.

*[**Table of Contents**](#toc)*<br>

Contingent liabilities classified as having a possible risk of loss refer to judicial and administrative proceedings involving tax matters which were deemed by our management, based on the advice of our legal counsel, as having a possible risk of loss, and were not recognized as liabilities. Such main lawsuits include:

&nbsp;&nbsp;&nbsp;&nbsp;• *PIS/COFINS Litigation*: We and our subsidiaries filed lawsuits seeking to invalidate the provisions
of Law No. 9,718/1998, according to which PIS and COFINS must be levied on all revenues of legal entities. Prior to the said rule being
in force, which had already been overruled in numerous recent decisions by the Brazilian Federal Supreme Court (Supremo Tribunal Federal),
or the "STF," in relation to nonfinancial corporations, PIS and COFINS were levied only on revenues related to the sale of
goods. On April 23, 2015, the STF issued a decision applicable only to Santander Brasil, accepting jurisdiction over the appeal relating
to PIS and rejecting jurisdiction over the appeal relating to COFINS. The tax authorities appealed the decision of the STF regarding COFINS,
which was rejected on August 19, 2015. Regarding COFINS, the case is closed, with a decision in favor of Santander Brasil. The Federal
Supreme Court issued a decision, recognizing the general repercussion of the issue being discussed, in which it partially granted the
Brazilian federal government's appeal, giving support to the argument that PIS/COFINS are levied on operating revenues arising from
the typical activities of financial institutions. With the publication of the ruling, we filed a new appeal in relation to PIS, and are
awaiting its analysis. Based on the assessment of our legal advisors, the prognosis of the risk was classified as a possible loss. As
of December 31, 2025, such claims amounted to R$5,419.9 million, of which R$3,071.2 million were established for the respective obligations.

&nbsp;&nbsp;&nbsp;&nbsp;• *Losses on loans*: We have challenged tax assessments issued by the Brazilian Federal Revenue Service
claiming that our deduction of losses on loans from IRPJ and CSLL bases did not meet the relevant requirements under applicable law. As
of December 31, 2025, the amount related to this challenge was approximately R$1,153.0 million.

&nbsp;&nbsp;&nbsp;&nbsp;• *Social Security Contribution – Profit Sharing Payments (Participação nos Lucros e Resultados), or "PLR"*: We are involved in administrative and judicial proceedings arising from a tax assessment with
respect to the collection of social security contributions on profit sharing payments. The tax authorities claim that payments by us were
not made in accordance with the law. We have appealed these assessments, as we consider our tax treatment to be appropriate based on the
applicable law and the nature of the payments. As of December 31, 2025, amounts related to these proceedings totaled approximately
R$11,090.4 million.

&nbsp;&nbsp;&nbsp;&nbsp;• *IRPJ and CSLL on Capital Gains Litigation*: The Brazilian Federal Revenue Service issued a tax
assessment against Santander Seguros S.A. (the legal successor of ABN AMRO Brasil Dois Participações S.A., or "AAB
Dois Par") charging income tax and social contribution related to the 2005 fiscal year. The Brazilian Federal Revenue Service claims
that the capital gain on the sale of Real Seguros S.A. and Real Vida e Previdência S.A. by AAB Dois Par should be paid at a 34.0%
tax rate instead of 15.0%. The assessment was appealed at the administrative level based on our understanding that the tax treatment adopted
in the transaction was in compliance with the applicable tax laws and the capital gain was properly taxed. The administrative discussion
ended unfavorably. We filed a lawsuit requesting the cancellation of tax assessments. We are responsible for any adverse outcome in this
proceeding as the former controlling shareholder of Zurich Santander Brasil Seguros e Previdência S.A. As of December 31, 2025,
the amount related to this proceeding was approximately R$602.5 million.

&nbsp;&nbsp;&nbsp;&nbsp;• *Goodwill amortization of the acquisition of Banco Sudameris*: In December 2012, we received
 a tax assessment of R$196 million related to the deduction of goodwill amortization relating to the acquisition of Banco Sudameris.
 In November 2014, we received a similar tax assessment in
the amount of R$239 million relating to the fiscal years encompassing May 2009 to July 2012. We have appealed both cases to the Board
of Tax Appeals (*Conselho Administrativo de Recursos Fiscais*), or "CARF." The first tax assessment is currently pending
judgment at CARF. As for the second tax assessment, CARF issued a partially favorable decision, leading to a separate proceeding to determine
the payable amount. We have requested the withdrawal of the appeal to benefit from Law No. 14,689/2023, which provides for reduced fines
in cases previously decided by casting votes (i.e., when the chairperson of the CARF panel, representing the tax authorities, casts the
deciding vote to break a tie). We are currently awaiting judgment by the court. We consider our risk of loss in this case as possible.
As of December 31, 2025, the amount related to this proceeding was approximately R$836.4 million.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• *Unrecognized Compensation Litigation*: We are currently engaged in legal and administrative proceedings
with the Brazilian Federal Revenue Service relating to the failure to ratify certain tax offsets with credits we were owed by the Brazilian
government due to overpayment or undue payment. As of December 31, 2025, the amount related to these proceedings was approximately
R$7,067.1 million. The risk of loss is classified as possible.

&nbsp;&nbsp;&nbsp;&nbsp;• *ISS on Financial Institutions Litigation*: We are currently party to proceedings relating to the
payment of ISS to various municipalities with respect to various revenues arising from operations that are usually not classified as services.
On December 31, 2025, the amounts related to these proceedings totaled approximately R$3,777.7 million.

&nbsp;&nbsp;&nbsp;&nbsp;• *Use of CSLL Tax and Negative Tax Loss*: We are currently party to proceedings relating to tax
assessments issued by the Brazilian Federal Revenue Service for the periods of 2009 and 2019. These proceedings relate to the alleged
undue compensation of tax loss carryforwards and negative basis of CSLL, because of tax assessments drawn up in previous periods. A judgment
is pending at the administrative level. As of December 31, 2025, the amount related to these assessments was R$2,728.9 million.

&nbsp;&nbsp;&nbsp;&nbsp;• *IRRF - Payment for services provided abroad*: We filed a judicial measure to avoid the imposition
of Income Tax – IRRF on payments derived from the provision of technology services by companies headquartered abroad, due to the
existence of international treaties to avoid double taxation between Brazil and Chile, Brazil and Mexico, and Brazil and Spain. A favorable
decision was handed down and an appeal was filed by the tax authority with the Federal Regional Court, where it awaits judgment. The risk
of loss is classified as possible. As of December 31, 2025, the amount related to these assessments was R$1,524.4 million.

***Labor Litigation***

Similar to many other Brazilian banks, we are party to lawsuits brought by labor unions, associations and individual employees seeking, in general, compensation for overtime work, lost wages and retiree complaints about pension benefits and other labor rights. We believe we have either paid for or adequately provisioned all such potential liabilities. In addition, we are the defendants in labor lawsuits filed by third-party employees that rendered or render services to us through service providers. The Brazilian Superior Labor Court has issued a binding judicial precedent determining that if a third-party service provider fails to pay its employee, the employee has the right to demand payment directly from the company to which it rendered their services (secondary liability). If this happens, the service taker's liability will be limited to the services that were rendered by each individual. As of December 31, 2025, our labor proceedings with a probable risk of loss amounted to R$3,761.2 million, which has been provisioned. Our labor proceedings with a possible risk of loss amounted to R$1,493.4 million.

*Abusive Targets Class Action*

In 2017, the Brazilian Labor Prosecutor's Office (*Ministério Público Federal do Trabalho*), or the "MPT," filed a class action against Santander Brasil alleging that the method used to define and assess employees' corporate targets is abusive and inappropriate. Specifically, the class action alleges that we apply constant pressure to meet those targets, which would allegedly be abusive, apply excessive and continuously increased goals, make excessive and inappropriate demands, impose an excessive workload resulting in physical and psychological strain, make constant threats of dismissal for failure to meet targets, have a staff too small to deal with the existing workload, run an organizational model based on stress and humiliation. The complaint further alleges that, as a result, we have allegedly caused irreparable damage to our employees' physical and mental health as a result of which the public social security system has suffered losses of more than R$90 million due to the 7,677 accident-related and social security benefits granted to employees from 2010 to 2015.

The MPT's complaint demands that we refrain from imposing certain corporate targets, refrain from subjecting employees to abusive targets, reduce the target levels, refrain from increasing targets by more than 10% per year, institute a quarterly targeting system, and refrain from adopting targets for operational areas. There is also a claim for the payment of indemnity for collective moral damages in an amount of not less than R$460 million, and that we be prohibited from contracting with the government for 10 years. The MPT is also demanding that a fine of R$500,000 be set for any breach by us of the obligations imposed on us following the judgment.

*[**Table of Contents**](#toc)*<br>

The lower court ruling prohibited the submission of employees to abusive targets. It also determined that the targets should only be reviewed annually and that their annual variation should be subjected to collective bargaining between Santander Brasil and the unions. The ruling also prohibited us from setting targets for employees in the back office and control departments and required payment of compensation for collective moral damages in the amount of R$274.4 million, in addition to the imposition of certain daily fines. Finally, the ruling determined that we are required to implement a new experimental target program under the terms provided for in the decision dated January 1, 2020. We appealed that decision. However, we were unsuccessful in our appeal, and the judgment reinstated the lower court ruling with respect to compliance with the targets. We filed an appeal for review and a stay was granted by the appeals court, which imposed a restriction on the defense, annulled the lower court decision and ordered that the case be tried again. The prior decision was reaffirmed in this new trial, following which we filed another appeal for review which is pending as of the date of this annual report. The preliminary injunction granted in the appeal for review remains in force, so we will only have to comply with the first instance judgment when it becomes final and unappealable. We estimate the risk of loss as possible.

***Civil Litigation***

We are a party to civil lawsuits claiming damages and other civil remedies. These disputes normally fall within one of the following categories: (i) actions requesting the review of contractual terms and conditions or seeking monetary adjustments, including the alleged effects of implementation of certain economic government plans (as described below); (ii) actions arising from loan agreements; (iii) execution actions; and (iv) actions seeking damages. As of December 31, 2025, our probable loss risk in connection with civil proceedings amounted to R$3,189.5 million, which has been fully provisioned, and our possible loss risk in connection with civil proceedings amounted to R$2,225.6 million. For civil lawsuits considered to be common and similar in nature, provisions are recorded based on statistically averaged previous payments and on legal counsel's evaluation of success. Provisions for other lawsuits are determined individually on a case-by-case basis.

*Economic Plans*

Like the rest of the banking system, we have been the subject of claims from customers and depositors and of class actions brought for a common reason, arising from a series of legislative changes relating to the calculation of inflation in the 1980s and 1990s ("planos econômicos"). The claimants considered that their vested rights had been impaired due to the immediate application of these adjustments. The claims relate to adjustments to the calculation of inflation applied on the amounts held in (i) savings deposit accounts (*depósitos em conta poupança*); (ii) time deposits (CDBs); and (iii) court deposits (*depósito judicial*).

In April 2010, the STJ set the statute of limitation for these class actions at five years, as claimed by the banks, rather than 20 years, as sought by the claimants. There are no new claims in connection with this matter due to the statute of limitations. The decisions issued to date have been adverse for the banks, although some proceedings have been brought to the STJ and the STF, where it is expected that they will be definitively settled. In August 2010, the STJ handed down a decision finding for the plaintiffs as to the merits, but excluding one of the plans from the claim, thereby reducing the amount of the award and once again confirming the five-year statute of limitations. Shortly thereafter, the STF issued an injunctive relief order whereby the proceedings in progress are stayed until the court issues a final decision. Although the STF initiated judgment in November 2013, a formal ruling has not been handed down as of the date hereof and we cannot predict when a formal ruling will be handed down by either the STJ or the STF.

In December 2017, the Brazilian Attorney-General's Office (Advocacia-Geral da União), the Brazilian Central Bank, the Brazilian Consumer Protection Institute (Instituto Brasileiro de Defesa do Consumidor), the Brazilian Savers' Association (Frente Brasileira pelos Poupadores) and the FEBRABAN signed an agreement to resolve existing disputes over the impact of the economic plans on the amounts held by claimants in savings deposit accounts. The settlement discussions did not address the full value of the payments and focused on setting the amount that would be paid to each person according to the relevant balance at the plan date. The total amount of the payments will depend on the number of persons adhering, as well as on the number of persons who proved in court the existence of the account and the balance on the date of the anniversary of the change in indices. The terms of agreement were negotiated between the parties and submitted to the STF, which approved the terms of the agreement on March 1, 2018 (for further details about the agreement, please see the specific section on "Cartilha Planos Econômicos" on the FEBRABAN's website, which is not incorporated herein by reference). All existing claims were suspended for two years, during which period claimants must decide whether or not they will adhere to the agreement. On March 3, 2020, the agreement was extended by means of an amendment, with the inclusion of actions that involve only the discussion of the Collor I Plan. This extension has a term of five years. The approval of the terms of the amendment occurred on June 3, 2020.

*[**Table of Contents**](#toc)*<br>

In November 2018, the STF handed down a decision recognizing the leading case status (repercussão geral) of an appeal discussing the matter of understated inflation in the monetary restatement of court deposits and determined that procedures related to this matter will be stayed until a final decision is reached by the court. Following ratification of the amendment to the settlement agreement in 2020, the STF determined an additional stay of the proceedings related to the matter for five years.

In May 2025, the judgment in Claim of Non-Compliance with a Fundamental Precept (Arguição de Descumprimento de Preceito Fundamental), or "ADPF," No. 165 recognized the constitutionality of the Bresser, Verão, Collor I and Collor II plans, guaranteed savers the amounts established in the collective agreement and set a 24 month deadline for new adhesions by savers. We believe that the provisions we have established are sufficient to cover the risks associated with the economic plans, considering the approved agreement.

*Fundo de Investimento em Direitos Creditórios Trendbank Banco de Fomento – Multisetorial*

A legal proceeding was filed against us in connection with the provision of custody services to Fundo de Investimento em Direitos Creditórios Trendbank Banco de Fomento – Multisetorial, or the "Fund," related to the acquisition of fake or defective bonds. In a decision by the first instance court, the case was dismissed in relation to us on the grounds that the custodian could not be held responsible for the acquisition of bonds. On appeal, the court reversed the decision of the lower court as a result of which the case will be retried following the expert phase. We estimate the risk of loss as possible.

Similar proceedings have been brought by the Federal General Accounting Office (*Tribunal de Contas de União*), or the "TCU," and the CVM to determine the liability for losses caused to pension funds as a result of their investments in the Fund. The pension funds involved in the CVM proceeding are PETROS – Fundação Petrobras de Seguridade Social and Postalis – Instituto de Previdência Complementar. Only damages to Postalis are under discussion in the TCU proceeding. The status of these and other legal proceedings in which losses incurred by the Fund are being discussed are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• *TC* U Proceedings: in 2021, the TCU handed down a favorable decision to Santander Brasil. There
was an appeal, but the decision was upheld and the case was closed for Santander Brasil.

&nbsp;&nbsp;&nbsp;&nbsp;• CVM Proceedings: Santander Brasil presented its defense, but in May 2022, Santander Brasil was ordered
to pay R$0.45 million, which was the subject of an appeal in August 2022. The appeal was partially granted and the sentence was reduced
to R$0.1 million.

&nbsp;&nbsp;&nbsp;&nbsp;• *Misconduct Proceedings*: initially, a single misconduct proceeding was filed against Santander
Brasil and its former manager. The proceeding was dismembered with respect to each party and, as of the date of this annual report, both
parties presented their defense and the proceedings are pending.

&nbsp;&nbsp;&nbsp;&nbsp;• *Popular Action Proceedings (Ação Popular) (class action)*: Santander Brasil presented
its defense, and the proceedings are now pending.

*IBAMA Litigation*

On October 10, 2016, after an inspection conducted in rural properties located in the State of Mato Grosso, the Brazilian Environment Authority *(Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis*), or "IBAMA," filed an infraction notice against us alleging that we had financed the production of corn in a protected area. The amount of the fine was set at R$47.5 million (approximately U.S.$8.5 million). According to IBAMA, financing seed production in protected areas is considered an environmental infraction due to the potential environmental damage that it may cause. We filed an administrative defense on November 9, 2016, stating that we had not financed production in a protected area, given that the financing agreement with the property owner had no connection with the production of seeds. Even though IBAMA failed to present any new evidence with respect to this matter within the three-year limitations period, it has decided to maintain the fine, as a result of which the administrative proceedings have concluded. In January 2023, we filed a judicial complaint against IBAMA to annul these administrative proceedings. We believe that the risk of loss in these judicial proceedings is possible.

***Other Litigation***

In addition to the matters described above, we are from time to time subject to certain claims and party to certain legal proceedings incidental to the normal course of our business, including in connection with our lending activities, relationships with our employees and other commercial, privacy, data protection, cybersecurity, tax or climate matters. In view of the inherent difficulty of predicting the outcome of these legal matters, particularly where the claimants seek very large or indeterminate damages, or where the cases present novel legal theories, involve a large number of parties, are in the early stages of investigation or discovery, or have common elements but require assessment of circumstances on a case-by-case basis, we cannot state with confidence what the eventual outcome of these pending matters will be, what the timing of the ultimate resolution of these matters will be or what the eventual loss, fines or penalties related to each pending matter may be. We believe that we have made adequate provisions related to the costs anticipated to be incurred in connection with these various claims and legal proceedings and believe that liabilities related to such claims and proceedings should not have, in aggregate, a material adverse effect on our business, financial condition, or results of operations. However, in light of the uncertainties involved in such claims and proceedings, there is no assurance that the ultimate resolution of these matters will not significantly exceed the provisions currently accrued by us; as a result, the outcome of a particular matter may be material to our operating results for a particular period, depending upon, among other factors, the size of the loss or liability imposed and our level of income for that period.

Contingent liabilities classified as remote risk of loss refer to judicial and administrative proceedings involving other matters assessed by legal counsel that have not been provisioned. The main lawsuits are discussed in the following paragraphs.

In December 2008, the Brazilian Federal Revenue Service issued a tax assessment against us in the total amount of R$3.9 billion with respect to IRPJ and CSLL related to 2002 to 2004. The tax authorities assert that we did not meet the legal requirements for deducting amortization of the goodwill arising from the acquisition of Banespa. On October 21, 2011, a unanimous decision of the CARF was handed down to cancel the tax assessments corresponding to fiscal years 2002 to 2004. The Brazilian Federal Revenue Service appealed to the CARF's superior appeals panel (*Câmara Superior de Recursos Fiscais*) with respect to the merits, but not the fine, and the 2002 fiscal year, which was already subject to the statute of limitation. As a result, the assessment was reduced to R$1.8 billion. An annulment action was filed to dispute the unfavorable part of this decision. There has not yet been a decision in the first instance, but an injunction was granted to suspend the enforceability of the debt. In June 2010, the Brazilian Federal Revenue Service issued two other infraction notices in the total amount of R$1.4 billion, based on the same concepts as the previous notice, with respect to IRPJ and CSLL related to 2005 to 2007. In these cases, we were not granted a favorable decision, and it has been appealed on its merits, though there was a reduction in the fine of R$367 million, and the assessment was reduced to R$984 million, the proceedings were partially unfavorable. We have filed claims for cancellation of these tax assessments. As of December 2013, the Brazilian Federal Revenue Service issued another infraction notice, in the total amount of R$344 million with respect to income tax and social contribution related to 2008. We challenged this tax assessment and was granted a favorable decision by the trial court. The tax authority has appealed the decision and this was accepted. After being denied by the CARF, the discussion on the merits was closed, but the case returned for analysis of the other issues, and we requested that the appeal be withdrawn in order to apply the benefits granted by Law No. 14,689/2023. This law offers a reduction in fines for taxpayers involved in cases previously decided by casting votes (i.e., when the chairperson of the CARF panel, representing the tax authorities, casts the deciding vote to break a tie). A lawsuit was filed and is awaiting judgment. In accordance with the advice of our external legal counsel, we believe that the Brazilian Federal Revenue Service's position is incorrect, and that the risk of loss is remote. We did not record any provision since this issue should not have an impact on our consolidated financial statements.

In addition, in June 2013, the Brazilian tax authorities issued an infraction notice against us as the local responsible party liable for the tax on the capital gain allegedly obtained in Brazil by an entity which is not resident in Brazil, Sterrebeeck B.V., as a result of a merger (incorporação de ações) transaction carried out in August 2008. Through this transaction, we acquired all the shares of Banco Real and AAB Dois Par by providing the shareholders of these entities' newly issued shares through a capital increase carried out for that purpose. The Brazilian tax authorities take the view that in the aforementioned transaction Sterrebeeck B.V. obtained a gain subject to tax in Brazil consisting of the difference between the issuance value of our shares that were received and the acquisition cost of the shares delivered in the exchange. Although Sterrebeeck B.V., as the final beneficiary of the transaction, is also the responsible for any costs arising from this litigation, we are handling the lawsuit as the local tax responsible party. A new appeal was filed with the CARF, which is awaiting judgment. This appeal was partially allowed, and we filed an injunction challenging the unfavorable portion. The case is currently awaiting judgment. Separately, we appealed the infraction notice before CARF, which was dismissed in March 2018 by a casting vote (i.e., when the chairperson of the CARF panel, representing the tax authorities, casts the deciding vote to break a tie). A subsequent administrative appeal was filed; however, in August 2024, we opted to withdraw this appeal to take advantage of the benefits provided by Law No. 14,689/2023. This law offers a reduction in fines for taxpayers involved in cases previously decided by casting votes. The administrative appeal was withdrawn, following which the lawsuit was filed and is currently awaiting judgment. Based on advice from our external legal counsel, we believe the Brazilian tax authorities' position is incorrect and that there are strong grounds for appeal against the infraction notice. Considering that any financial impacts arising from this lawsuit will be the responsibility of Sterrebeeck B.V. or its successors, we have not made any provisions in connection with these proceedings. Consequently, the risk of loss is considered remote.

*[**Table of Contents**](#toc)*<br>

On December 8, 2016, the general superintendent of the CADE began an investigation into alleged anticompetitive conduct in the real onshore foreign exchange market. The investigation concerns 11 financial institutions, including Santander Brasil, and 19 individuals active in the Brazilian foreign exchange market between 2009 and 2012. On January 8, 2018, we filed an administrative defense stating our understandings that there is no evidence that we were involved in the alleged conduct. We expect that these investigations will not have a significant financial impact on us.

*Former Employees of Banco do Estado de São Paulo S. A. Litigation*

A claim was filed in 1998 by the association of retired Banespa employees, the "AFABESP," requesting the payment of a half-yearly bonus contemplated in the bylaws of Banespa in the event that Banespa obtained a profit and that the distribution of this profit was approved by the board of directors of Banespa. The bonus was not paid in 1994 and 1995 since Banespa had not made a profit during those years. Partial payments were made from 1996 to 2000, as approved by the board of directors of Banespa. The relevant clause in the bylaws was repealed in 2001. The Brazilian Regional Labor Court and the Brazilian Superior Labor Court ordered Santander Brasil, as successor to Banespa, to pay this half-yearly bonus for the period from 1996 to the present. On March 20, 2019, a decision of the STF rejected the extraordinary appeal filed by Santander Brasil. We have brought a rescission action to revert the decision in the main proceedings and suspend procedural enforcement. The rescission action was dismissed in 2020 and an appeal has been filed but has not yet been the subject of a decision as of the date of this annual report.

A decision of the Regional Labor Court in July 2021 determined that the execution should be individualized and in the corresponding courts of the residence each person represented by AFABESP. Due to this decision, 7,444 individual enforcement actions of the collective judgment were filed. Since the judgments adopted different positions for each case, a procedure to resolve these inconsistent demands was instituted before the Regional Labor Court (*Tribunal Regional do Trabalho*) with the purpose of establishing objective criteria with respect to these claims, mainly the statute of limitations and limitation of payments until December 2006 (Plan V). On March 11, 2024, it was determined that all cases filed in the city of São Paulo should remain suspended. Finally, due to the diverging interpretations of the Brazilian federal constitution, an action for allegation of non-compliance with a fundamental precept was also filed, so that the Federal Supreme Court (*Supremo Tribunal Federal*) settles the issue and indicates the correct statute of limitations to be used in the individual cases filed. On June 27, 2024, an agreement was signed between the parties which includes an exhaustive list of 7,299 retirees who, according to the criteria presented by Santander Brasil, are entitled to payment of the amounts related to half-yearly bonuses. The total value of the agreement is R$2.7 billion. However, whether such agreement would be binding upon any given plaintiff was contingent on the individual and voluntary adherence of such plaintiff by August 15, 2024, while the deadline for judicial approvals was October 15, 2024. After the end of the voluntary adherence period and of the judicial approvals, payments were or will be made in five installments for living retirees (the first installment falling due on October 20, 2024, and the other four installments in the months of December 2024, May 2025, December 2025 and May 2026) and in a single installment for deceased people (October 31, 2024). As of December 31, 2025, 6,500 agreements (98%) were recorded, totaling R$2,473.0 million. The payments are following the agreed dates, depending on whether the retirees are alive or deceased.

*IGP-DI Litigation*

In 2002, AFABESP filed a lawsuit in the Federal Court of Brazil on behalf of its associates, requesting the readjustment of certain social security supplements to which individuals admitted to the respective retirement plan before May 22, 1975 were entitled, according to the General Price Index for Internal Availability in Brazil (General Price Index – Internal Availability), or the "IGP-DI," inflation index. The lawsuit was initially decided unfavorably for Santander Brasil, which appealed the initial decision, and on August 23, 2024, a ruling was issued in favor of Santander Brasil. Following this new decision, on August 30, 2024, AFABESP filed a motion for clarification, which was decided in favor of Santander Brasil. AFABESP appealed, and we are awaiting a new decision. Based on the assessment of our legal advisors, the risk of loss is remote, which is why no provision was recorded.

**Dividend Policy**

***General Rules***

We are required by Brazilian Corporate Law and our By-Laws to hold an annual general shareholders' meeting by no later than the fourth month after each fiscal year, at which time, the allocation of the net profits of the preceding year and the distribution of an annual dividend are approved by our shareholders. The payment of annual dividends is based on our consolidated audited financial statements prepared for the immediately preceding fiscal year.

Our By-Laws provide that an amount equal to at least 25.0% of our adjusted net income, after deducting allocations to the legal and contingency reserves, should be available for distribution as a dividend or interest attributable to shareholders' equity in any given year. This amount represents the mandatory dividend.

Our board of directors may declare interim dividends or interest attributable to shareholders' equity based on income verified in semiannual consolidated financial statements. The board of directors may also declare dividends or interest attributable to shareholders' equity based on consolidated financial statements prepared for shorter periods, provided that the total dividends paid in each six-month period do not exceed the capital reserves amount required by Brazilian Corporate Law. The board of directors may also declare interim dividends or interest attributable to shareholders' equity out of retained earnings or income reserves recorded in the last annual or semiannual balance sheet. Any payment of interim dividends or interest on shareholders' equity may be set off against the mandatory dividends relating to the net income earned in the year in which the interim dividends were paid.

The amount distributed to shareholders as interest attributable to shareholders' equity, net of any withholding tax, may be included as part of the minimum mandatory dividend. In accordance with applicable law, we are required to pay to shareholders an amount sufficient to ensure that the net amount they receive in respect of interest attributable to shareholders' equity, after payment of the applicable withholding tax, plus the amount of declared dividends, is at least equivalent to the amount of the minimum mandatory dividend.

However, Brazilian Corporate Law allows our shareholders to suspend dividends distribution if our board of directors reports at our annual shareholders' meeting that the distribution would not be advisable given our financial condition. Our fiscal council, if installed, should review any suspension of the mandatory dividend. In addition, our management should submit a report to the CVM setting out the reasons for the suspension. Net income not distributed by virtue of a suspension is allocated to a separate reserve and, if not absorbed by subsequent losses, is required to be distributed as a dividend as soon as our financial condition permits such payment.

***Current and Future Dividend Policy***

Our board of directors currently recommends to our shareholders a 50% distribution of our yearly adjusted net income as dividends and/or interest attributable to shareholders' equity. Our future dividend policy and the amount of future dividends and/or interest attributable to shareholders' equity we decide to recommend to our shareholders for approval will depend on a number of factors, including, but not limited to, our cash flow, financial condition (including capital position), investment plans, prospects, legal requirements, economic climate, regulatory provisions .and such other factors as we may deem relevant at the time.

***Payment of Dividends***

Any shareholder as of the record date set once a dividend is declared is entitled to receive dividends. Under Brazilian Corporate Law, dividends are generally required to be paid within 60 days following the date on which the dividend is declared, unless the shareholders' resolution establishes another payment date, which must occur prior to the end of the fiscal year in which such dividend was declared. Based on Brazilian Corporate Law, unclaimed dividends do not bear interest, are not monetarily adjusted and may revert to us three years after being declared.

The depositary is the registered owner of the units underlying the ADRs on the records of the registrar. Such units are held since December 13, 2016 by S3 Caceis Brasil Distribuidora de Títulos e Valores Mobiliários S.A. in Brazil, acting as the custodian and agent for the depositary for our ADRs.

Payments of cash dividends and distributions, if any, are made in *reais* to the custodian on behalf of the depositary, which then converts such proceeds into U.S. dollars and causes such U.S. dollars to be delivered to the depositary for distribution to holders of ADRs. In the event that the custodian is unable to convert the Brazilian currency received as dividends into U.S. dollars immediately, the amount of U.S. dollars payable to holders of ADRs may be adversely affected by changes in the exchange rate for *reais* into U.S. dollars.

*[**Table of Contents**](#toc)*<br>

The following table sets forth the amounts available for distribution as dividends based on the Brazilian GAAP calculation of net income on a consolidated basis. The reconciliation of net income under Brazilian GAAP to net income under IFRS is presented in Appendix I of our audited consolidated financial statements for the years ended December 31, 2025, 2024 and 2023:

**Market Price and Volume Information**

On September 18, 2009, our Board of Directors approved the implementation of a global public offering, which included the issue of 525,000,000 units (each representing, at that date, 55 common shares and 50 preferred shares), which were all registered, without par value, free and clear of any liens or encumbrances. This offering consisted of the simultaneous initial public offering of (i) units in Brazil on the over-the-counter market, in accordance with CVM Resolution 160, of July 13, 2022, as amended, and (ii) units abroad, including in the form of ADRs representing ADSs registered with the SEC under the Securities Act. On October 6, 2009, the global public offering priced shares at R$23.50 per unit and U.S.$13.40 per ADR. The units have been traded on the B3 and since October 7, 2009, and our ADRs have been traded on the NYSE since October 7, 2009.

On April 29, 2014, Santander Spain, our indirect controlling shareholder, announced its intention to launch voluntary exchange offers in Brazil and in the United States, or the Exchange Offers, to acquire up to all of our shares that were not held by the Santander Group, representing approximately 25% of our share capital, with payment in Brazilian depositary receipts or ADRs representative of Santander Spain's common shares. On October 30, 2014, such exchange offers were concluded. As a result, the Santander Group's shareholding increased to 88.3% of our total share capital. Further, as a result of the offer in Brazil, our units were delisted from the Level 2 Segment and are now traded on the basic listing segment of the B3.

The price of our units and ADSs may experience volatility, which could negatively impact holders of our units and ADSs.

The following table shows our outstanding publicly traded common shares and preferred shares as of January 31, 2026:

***ADRs Traded on NYSE***

Our ADRs have been listed and traded on the NYSE since October 7, 2009. Our units abroad, including in the form of ADRs representing ADSs, are registered with the SEC under the Exchange Act.

The deposit agreement pursuant to which ADRs have been issued is between us and The Bank of New York Mellon, as depositary, and all the holders from time to time of ADRs. For further information on our arrangements with The Bank of New York Mellon, please see "Item 12. Description of Securities other than Equity Securities—D. American Depositary Receipts."

Since certain of our shares and our ADRs are held by nominees, the number of record holders may not be representative of the number of beneficial owners.

**9B. Plan of Distribution**

Not applicable.

**9C. Markets**

Our units and common and preferred shares are traded on the B3. The regulation of Brazilian securities markets which affects these securities is discussed below. In addition, we also have ADRs which have been listed and traded on the NYSE since October 7, 2009. For further information, see "—A. Offering and Listing Details."

**Regulation of Brazilian Securities Markets**

The Brazilian securities market is regulated by the CVM, as provided for in Brazilian Law No. 6,385/76, as amended, and by the Brazilian Corporate Law, as well as the CMN and the Brazilian Central Bank.

Under Brazilian Corporate Law, a corporation is either publicly held (*companhia aberta*) or privately held (*companhia fechada*) and unlisted. All publicly held companies must be registered with the CVM and are subject to reporting and other regulatory requirements. A company registered with the CVM may list its securities either on the Brazilian stock exchange market or on Brazilian over-the-counter markets. The shares of a publicly held company may also be traded privately.

*[**Table of Contents**](#toc)*<br>

In Brazil, the over-the-counter market is divided into two categories: (i) organized over-the-counter markets, in which the transactions are supervised by self-regulating entities authorized by the CVM; and (ii) non-organized over-the-counter markets, in which the transactions are not supervised. In either case, the over-the-counter markets consist of direct trades, outside of the stock exchange market, through a financial institution registered with the CVM, which serves as an intermediary. No special application, other than registration with the CVM (and, in case of organized over-the-counter markets, registration with the applicable one), is necessary for securities of a public company to be traded in these markets.

To be listed on the B3, a company must apply for registration with the CVM and the B3.

**Trading on the B3**

The B3 currently facilitates all trading activities of shares and commodities in Brazil, including settlement, clearing and depositary services.

Trading on the Brazilian stock exchange is conducted by authorized members. Trading sessions in the shares market take place every business day, from 10:00 a.m. to 5:00 p.m. between March and October and from 10:00 a.m. to 6:00 p.m. between November and February, on an electronic trading system called PUMA. Trading is also conducted from March to October between 5:30 p.m. and 6:00 p.m. in an after-market system connected to both traditional brokerage firms and brokerage firms operating on the internet. This after-market trading is subject to regulatory limits on price volatility of securities traded by investors operating on the internet.

The trading of securities on the B3 may be suspended at the request of a company in anticipation of a material announcement. Trading may also be suspended on the initiative of the B3 or the CVM, among other reasons, based on or due to a belief that a company has provided inadequate information regarding a significant event or has provided inadequate responses to inquiries by the CVM or the B3.

In addition, in order to maintain control over the fluctuation of the B3 index, the B3 has adopted a "circuit breaker" system pursuant to which trading sessions may be suspended for a period of 30 minutes, one hour, or a time to be defined by B3, whenever the B3 index falls below 10.0%, 15.0% or 20.0%, respectively, in relation to the value of closing index of the previous trading session.

When investors trade shares on the B3, the trade is settled two business days after the trade date, without adjustments to the purchase price. The seller is ordinarily required to deliver the shares to the exchange on the second business day following the trade date. Delivery of and payment for shares are made through the facilities of an independent clearing house, a division of the B3, which handles the multilateral settlement of both financial obligations and transactions involving securities. According to the regulations of the B3, financial settlement is carried out through the system of transfer of funds of the Brazilian Central Bank and the transactions involving the sale and purchase of shares are settled through the B3 custody system. All deliveries against final payment are irrevocable.

In order to keep our securities listed on the B3, we are required to comply with the provisions of the B3's Issuers Regulations (*Regulamento de Emissores*), which establishes technical and operational procedures and criteria applicable to companies that have securities listed on the B3. The most up-to-date version of the B3's Issuers Regulations became effective as of August 19, 2023.

**Corporate Governance Practices**

In 2000, the B3 introduced three special listing segments, Levels 1 and 2 of Corporate Governance and Novo Mercado, which were aimed at fostering a secondary market for securities issued by Brazilian companies that voluntarily abide by corporate governance practices and disclosure requirements in addition to those already imposed by Brazilian law.

Our units were initially listed on the Level 2 Segment. However, as a result of the Exchange Offers and launched by Santander Spain in Brazil for the acquisition of our shares, our units were delisted from the Level 2 Segment and are now traded on the basic listing segment of the B3. For more information, see "Item 9. The Offer and Listing—A. Offering and Listing Details—Market Price and Volume Information."

Within the B3, we are a part of one sustainability index: the ISE (*Índice de Sustentabilidade Empresarial –* Entrepreneurial Sustainability Index) which is a reference for socially responsible investments in Brazil. To be part of the portfolio, currently composed of 78 companies from 36 sectors (ISE 2024), the company's performance is evaluated with respect to sustainability, including economic efficiency, environmental balance, social practices and corporate governance.

*[**Table of Contents**](#toc)*<br>

In 2016, the Brazilian Code of Corporate Governance for Publicly-held Companies (*Código Brasileiro de Governança Corporativa – Companhias Abertas*), or the "Governance Code," was published by the Brazilian Institute of Corporate Governance (*Instituto Brasileiro de Governança Corporativa*). It sets forth corporate governance principles, guidelines and actions applicable for publicly held companies and establishes a "comply or explain" enforcement model. On June 8, 2017, following a public consultation on the implications of the Governance Code for Brazilian companies, the CVM issued Normative Ruling No. 586 introducing the necessary changes to the existing securities regulation in order to make these consistent with the provisions of the Governance Code. These changes were incorporated to CVM Resolution No. 80, issued on March 29, 2022, which repealed CVM Normative Ruling No. 586.

The rules initially established by Normative Ruling No. 586 and incorporated to Resolution No. 80 apply to companies (i) which are registered as category "A" issuers with the CVM, (ii) which have securities admitted for trading in the stock market by an authorized stock exchange (*entidade administradora de mercado organizado*), and (iii) which has issued and outstanding shares or units not held by controlling shareholder, any affiliates of the controlling shareholder or by the relevant company´s directors or officers. We fulfill all three of these criteria and are therefore subject to these rules.

**Investment in Our Units by Non-Residents of Brazil**

Investors residing outside Brazil, including institutional investors, may either register their investments in securities in Brazil, as a foreign direct investment under the New Foreign Exchange Law, or as a portfolio investment under the applicable regulation enacted by CMN and CVM. Foreign investors, regardless of whether their investments are made as direct investments or portfolio investments, must be enrolled with the Brazilian Internal Revenue. This registration process is undertaken by the investor's legal tax representative in Brazil.

Since January 1, 2025, portfolio investments are regulated by Joint Resolution No. 13, enacted on December 3, 2024, or "Joint Resolution No. 3," which superseded CMN Resolution No. 4,373, which had been in force for about 10 years.

The main purpose of Joint Resolution No. 13 is to facilitate the entry of foreign investors in the Brazilian financial and capital markets. Joint Resolution No. 13 introduces the possibility for foreign investors to make investments in local currency with funds held in their foreign bank accounts, or with bills of payment denominated in *reais* but issued abroad, without the need of converting these availabilities into portfolio investments by means of the execution of a simultaneous and symbolic foreign exchange transaction, which was previously required under CMN Resolution No. 4,373, as well as the possibility of the foreign investor making an investment directly from a nonresident checking or payment account in Brazilian *reais* opened with a local financial or payment institution. Reporting and local representation requirements applicable to this type of investment were also simplified.

With certain limited exceptions, Joint Resolution No. 13 allows investors to carry out any type of transaction in the Brazilian capital markets involving a security traded on a Brazilian stock or futures exchange, or through an organized over-the-counter market, but investors may not transfer the ownership of investments made under such regulation to other non-Brazilian holders through private transactions, except if previously and expressly authorized by the CVM. Investments and remittances outside Brazil for gains, dividends, profits or other payments under our units are made through the foreign exchange market, either through foreign exchange transactions or through the use of a nonresident checking or payment account opened by the foreign investor with a local financial or payment institution.

For further information on the requirements for the registration of foreign portfolio investments, see "Item 10. Additional Information—D. Exchange Controls—Foreign Investment in Brazil—Capital Markets Investment."

Foreign direct investors under the New Foreign Exchange Law may sell their shares in both private and open market transactions, but these investors are currently subject to a less favorable tax treatment on gains, apart from being subject to taxation on the execution of foreign exchange transactions. For more information on foreign direct investors, see "Item 10. Additional Information—D. Exchange Controls—Foreign Investment in Brazil—Foreign Direct Investment."

Joint Resolution No. 13 also deals with investments of foreign capital in Brazil through Depositary Receipts, or "DRs."

We filed an application to have the ADRs approved under the former rule by the Brazilian Central Bank and the CVM, and we received final approval on October 1, 2009.

If a holder of ADRs decides to exchange such ADRs for the underlying units, the holder will be entitled to (i) sell the units on the B3 and rely on the depositary's electronic registration for five business days from the date of exchange to obtain and remit U.S. dollars abroad upon the holder's sale of our units, (ii) convert its investment into a foreign portfolio investment under Joint Resolution No. 13 (without the need of executing a simultaneous and symbolic foreign exchange transaction for this purpose), or (iii) convert its investment into a foreign direct investment under the New Foreign Exchange Law (without the need of executing a simultaneous and symbolic foreign exchange transaction for this purpose). See "Item 10. Additional Information—E. Taxation—Brazilian Tax Considerations" for a description of the tax consequences for an investor residing outside Brazil of investing in our units in Brazil.

*[**Table of Contents**](#toc)*<br>

If a holder of ADRs wishes to convert its investment into either a foreign portfolio investment under Joint Resolution No. 13 or a foreign direct investment under the New Foreign Exchange Law, it should begin the process of obtaining its own foreign investor registration with the Brazilian Central Bank or with the CVM, as the case may be, in advance of exchanging the ADRs for units (assuming registration is required pursuant to the conditions and thresholds set forth in Joint Resolution No. 13 and the Brazilian Central Bank regulations governing foreign direct investments under the New Foreign Exchange Law).

The custodian is authorized to update the depositary's electronic registration to reflect conversions of ADRs into foreign portfolio investments. If a holder of ADRs elects to convert its ADRs into a foreign direct investment under the New Foreign Exchange Law, the conversion will be carried out by the Brazilian Central Bank after receipt of an electronic request from the custodian with details of the transaction. This may also require the units to be converted into shares.

If a foreign direct investor under the New Foreign Exchange Law wishes to deposit its units into the ADR program in exchange for ADRs, such holder will be required to present to the custodian evidence of payment of capital gains taxes. The conversion will be carried out by the Brazilian Central Bank after receipt of an electronic request from the custodian with details of the transaction. This may also involve the need to change the units into shares.

The Brazilian federal constitution permits foreign individuals or companies to invest in the voting shares of Brazilian financial institutions only if they have specific authorization by the President of Brazil based on national interest or reciprocity. A presidential decree issued on November 13, 1997, in respect of Banco Meridional do Brasil S.A. (a predecessor entity) allows up to 100% foreign participation in our capital stock. Foreign investors may acquire our units or ADRs as a result of this decree. In addition, foreign investors may acquire publicly traded nonvoting shares of Brazilian financial institutions traded on a stock exchange or depositary receipts offered abroad representing nonvoting shares without specific authorization. See "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Foreign Investment in Brazilian Financial Institutions."

**10B. By-Laws**

Below we provide a summary of the important provisions of our By-Laws and of the corporate and Brazilian capital markets legislation and regulations. This description is not intended to be exhaustive. It is based on our By-Laws (an English translation of which is attached as an exhibit to this annual report), as well as on the legislation and regulations applicable to companies and the Brazilian capital market currently in effect.

**Registration and Business Purpose**

We are a publicly held company, incorporated under Brazilian law. Our documents of incorporation are duly registered with JUCESP, under NIRE 35300332067.

*[**Table of Contents**](#toc)*<br>

Pursuant to article 4 of our By-Laws, our corporate purpose is to (i) participate in asset, liability and accessory transactions related to our respective authorized portfolios (commercial, investment, credit, financing and investment, real estate credit and leasing), (ii) carry out foreign exchange transactions; (iii) manage investment portfolios; (iv) any other transaction that would be allowed by law and regulations in force; and (v) participate, as shareholder or quotaholder, in other companies.

**Directors' and Executive Officers' Role and Conflict of Interests**

Brazilian Corporate Law imposes on the members of the Board of Directors and Officers the duty of diligence during the performance of their functions, as well as the duty of loyalty to the company, besides prohibiting members of the Board of Directors and the Officers from: (i) receiving any type of direct or indirect personal advantage from third parties, by virtue of the position occupied, without authorization in the By-Laws or from a shareholders' meeting; (ii) taking part in any corporate transaction in which he or she has an interest that conflicts with our interest or in the decisions made by other directors on the matter; (iii) use any commercial opportunity which may come to his or her knowledge, by virtue of his or her position, for his or her own benefit or that of a third party, whether or not harmful to the company; (iv) fail to exercise or protect the company's rights or to take advantage of a commercial opportunity of interest to the company, in seeking to obtain advantages for himself or herself or for a third party; and (v) acquire for resale with profit property or rights which he or she knows the company needs or which the company intends to acquire.

As a financial institution, we are subject to certain limitations set forth by the Banking Reform Law, as amended, Law No. 13,506/17, as well as related regulations. For more information in relation to such limitations, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Principal Limitations and Obligations of Financial Institutions" and "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—Administrative Proceedings in the Brazilian National Financial System, the Brazilian Payment System and Capital Markets."

In addition to these provisions, Article 10 of our By-Laws provides that members of the Board of Directors and Officers are forbidden to be involved in the analysis, approval or settlement of business deals or loans relating to a company where they (i) hold more than 5% of the capital stock as partners or shareholders, or where they are members of the management, or (ii) had been members within a period of up to six months before their appointment. Finally, our policy for transactions with related parties also sets forth procedures to be followed by managers involved in such transactions, and when other potential conflicts of interest may arise.

**Rights of Common Shares and Preferred Shares**

Each common share gives its holder the right to a vote at general meetings, however, the preferred shares do not grant voting rights in our shareholders' general meetings, except as related to the following matters:

&nbsp;&nbsp;&nbsp;&nbsp;• change of corporate status, merger, consolidation or spin-off;

&nbsp;&nbsp;&nbsp;&nbsp;• approval of agreements entered into between us and our controlling shareholder, directly or indirectly,
and agreements with other companies in which our controlling shareholder has an interest, whenever the law or the By-Laws provide that
they must be approved at a shareholders' general meeting; and

&nbsp;&nbsp;&nbsp;&nbsp;• the appraisal of assets to be contributed to increase our capital stock.

Regarding the election of members of the Board of Directors, the Brazilian Corporate Law sets forth that, when members of the Board of Directors are elected, the following parties have the right to elect one member of our Board of Directors:

&nbsp;&nbsp;&nbsp;&nbsp;• minority holders of shares in public companies holding a minimum of 15% of the total number of voting
shares, or

&nbsp;&nbsp;&nbsp;&nbsp;• holders of preferred shares without voting rights, or with restricted voting rights, representing 10%
of the capital stock, or

&nbsp;&nbsp;&nbsp;&nbsp;• holders of common and preferred shares who jointly represent at least 10% of the capital stock, in a
separate vote.

Nevertheless, these rights can only be exercised by the holders of shares who maintained their holding for at least three months before the date of the annual shareholders' meeting. The Brazilian Corporate Law also permits a multiple vote procedure to be adopted, upon request by shareholders representing at least 10% of our voting capital. Pursuant to CVM Resolution No. 70 of March 22, 2022, the percentage needed to call for a multiple vote to elect members of the board of directors, in public companies with capital stock exceeding R$100 million, is 5% of the voting capital per request of multiple vote.

*[**Table of Contents**](#toc)*<br>

The holders of preferred shares are entitled to the following rights according to our By-Laws:

&nbsp;&nbsp;&nbsp;&nbsp;• dividends and interest on shareholders' own equity in an amount 10% higher than those attributed
to common shares, as well as priority in the distribution;

&nbsp;&nbsp;&nbsp;&nbsp;• participation on equal terms with the common shareholders, in capital increases arising from the capitalization

other resources;

&nbsp;&nbsp;&nbsp;&nbsp;• priority in reimbursement of capital, without payment of premium, in the case of liquidation; and

&nbsp;&nbsp;&nbsp;&nbsp;• tag-along rights in the event of a change in our control, under the same terms and conditions extended
to our controlling shareholders.

Common shares not belonging to the controlling shareholders also give their holders tag-along rights in the event that our control is transferred on the same terms and conditions as those granted to our controlling shareholders.

The shareholders' general meeting may decide on conversion of the preferred shares into common shares.

The Brazilian Corporate Law sets forth that shares without voting rights or shares with restricted rights, including our preferred shares, shall be granted unrestricted voting rights if the company ceases to distribute, during three consecutive fiscal years, any fixed or minimum dividend granted to these shares, until the respective distributions are made.

According to our By-Laws, the dividends that are not claimed by shareholders within three years, from the beginning of their payment, shall be retained by us to our benefit.

Under the Brazilian Corporate Law, any change in the preferences or changes which would have an adverse financial effect on the rights of holders of preferred shares, or any change that results in the creation of a more favored class of preferred shares, must be approved by a resolution at a general shareholders' meeting and will become valid and effective only after approval by a majority of our preferred shareholders.

Brazilian Corporate Law also sets forth that the following shareholders' rights cannot be repealed or modified by our By-Laws or decisions made at shareholders' meetings:

&nbsp;&nbsp;&nbsp;&nbsp;• the right to vote at general meetings, in the case of holders of common shares;

&nbsp;&nbsp;&nbsp;&nbsp;• the right to share in the distribution of dividends and interest on shareholders' equity, and
to share in the surplus assets in the event of our liquidation;

&nbsp;&nbsp;&nbsp;&nbsp;• preemptive rights in subscribing for shares or convertible securities in specific circumstances;

&nbsp;&nbsp;&nbsp;&nbsp;• the right to monitor the management; and

&nbsp;&nbsp;&nbsp;&nbsp;• the right of withdrawal in the circumstances established by law, including our consolidation, merger
and spin-off.

**Description of Units**

The units are share deposit certificates, each representing one common share and one preferred share, all of them free and unencumbered. The shares represented by the units shall be registered in a trust account linked to the units, and their ownership can only be transferred by means of transfer of the corresponding units, upon written instructions from the holder. Earnings from the units and the amount received in the case of redemption or repayment shall only be paid to the holder of the units registered in the books of the custodian.

None of the shares underlying the units, the earnings thereon or the corresponding redemption or repayment amounts may be pledged, encumbered or in any other way given in guarantee by the holder of the units, nor may they be subject to attachment (*penhora*), seizure (*arresto*), impounding (*sequestro*), search and apprehension (*busca e apreensão*), or to any other lien or encumbrance.

*[**Table of Contents**](#toc)*<br>

The units are held by us (except units that underlie the ADSs which are held by our affiliate, S3 Caceis Brasil Distribuidora de Títulos e Valores Mobiliários S.A.), as the custodian, in book-entry form in an account opened in the holder's name. The transfer of ownership is effected by debiting the seller's unit custody account and crediting the buyer's unit custody account according to a written transfer order issued by the seller or a court authorization or transfer order delivered to the custodian, all of which are retained by the custodian. Dividends, interest on shareholders' equity and/or cash bonuses shall be paid to the custodian and the custodian shall then transfer the amount to the custody agents for payment to the unit holders. The pledge, usufruct, right of succession, fiduciary transfer in guarantee and any other conditions, onus or encumbrances on the units must be registered in the custodian's records, as well as noted in the corresponding statement of account of units.

The custodian shall provide unit holders with a statement of account at the end of each month in which there is movement and, when there is no movement, at least once a year. The statement shall show the date and place of issue, the name and details of the holder of the unit account, an indication that it is a statement of unit account, details of the shares deposited, a statement that the shares deposited, their earnings and any amounts received in the event of redemption or repayment shall only be paid to the holder of the unit account or to the holder's order in writing, our charge for the deposit, if any, and the addresses where unit holders may obtain assistance.

Upon a written order issued by the holder of the unit account to a broker authorized by the stock exchange where the units are traded, the custodian shall block the corresponding units and transfer them to the buyer upon receipt of a confirmation of the sale from the stock exchange.

The unit holder shall have the right, at any time, to instruct a broker to cancel units and transfer the underlying shares. The broker must request to us, as the agent, to transfer the units to the share deposit accounts held by the custodian in the holder's name. The unit holder shall bear any transfer and cancellation costs involved. Similarly, the holder may instruct a broker to assemble units by transferring the number of shares that jointly represent a unit, which shall be registered by the custodian in a trust account linked to the units.

The right to cancel units may be suspended in the event of a public offering for distribution of units, either in the domestic or the international market, in which case the suspension may not last longer than 180 days. Units subject to any lien or encumbrance may not be cancelled.

The following rules apply to the exercise of the rights granted to the shares represented by units:

&nbsp;&nbsp;&nbsp;&nbsp;• Dividends and share redemption or repayment amounts delivered to us, as depository of the shares, shall
be paid by us to the unit holder;

&nbsp;&nbsp;&nbsp;&nbsp;• Only the unit holder shall have the right to attend our general meetings and to exercise all prerogatives
conferred on our shareholders by the shares represented by the units;

&nbsp;&nbsp;&nbsp;&nbsp;• In the event of a stock split, cancellation or reverse stock split or new issuances of shares by us
while the units are in existence, the following rules will be observed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) In the event there is a change in the number of shares represented by units as a result of a reverse
stock split or cancellation of shares, we will debit the number of cancelled shares from each unit holder's account and proceed
with the automatic cancellation of units, observing the ratio of one common share and one preferred share issued by us to each unit. We
will deliver to the shareholders the shares which are insufficient to constitute a unit in the form of shares, rather than units; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) In the event there is a change in the number of shares represented by the units as a result of a stock
split or new issuances of shares, the custodian will register the deposit of the new shares and issue new units, registering them in the
accounts of their respective holders, so as to reflect the new number of shares held by unit holders. In this way, the accounts will maintain
a ratio of one common share and one preferred share issued by us and represented by units, and the custodian will deliver to holders the
shares which are insufficient to constitute a unit in the form of shares rather than units;

In the event of a capital increase, by means of the issuance of shares that may be converted into new units, unit holders may exercise the preemptive rights belonging to the shares represented by their units. We shall create new units in the register of book-entry units and credit them to their holders so as to reflect the new number of common and preferred shares issued by us, subject to the current proportion of ordinary and preferred shares to constitute the units. Shares that are too few to constitute a unit shall be delivered to the shareholders as shares, rather than units. There shall be no automatic credit of units in the event of the exercise of preemptive rights in the issue of securities other than shares.

*[**Table of Contents**](#toc)*<br>

Unit holders will be entitled to receive any shares issued as a result of our spin-off, consolidation or merger.

**General Meetings**

At our duly convened general meetings, our shareholders are authorized to make resolutions on matters relating to our activities and to make decisions deemed to be in our best interests.

Our shareholders are exclusively responsible for approving the financial statements at the annual general meeting, and to decide on the destination of net earnings and the distribution of dividends for the year immediately preceding the meeting. The members of the Board of Directors and Fiscal Council are, as a general rule, elected at annual general meetings unless for an exceptional reason they have to be elected at an extraordinary general meeting.

An extraordinary general meeting may be held at any time, including together with an annual general meeting, Our shareholders in a general meeting are exclusively responsible for approving, among other matters: (i) amendments to our By-Laws; (ii) election and dismissal of members of our board of directors; (iii) creation of any reserves of profits, other than the legal reserve; (iv) suspension of the rights of a shareholder that has failed to comply with obligations under the law or our By-Laws; (v) approval of our consolidation, merger or spin-off; and (vi) approval of our dissolution or liquidation, approval of reports prepared by the liquidators and the election of a liquidator and members of the fiscal council to operate during a liquidation.

**Quorum of General Meetings**

As a general rule, the Brazilian Corporate Law sets forth that a general meeting can be held if shareholders holding at least 25% of voting shares are present, at the first call, and at the second call if any number of holders of voting shares are present. If the shareholders have been convened to resolve on amendments to the By-Laws, the quorum at the first call must be at least two-thirds of the voting shares and, at the second call, any number of holders of voting shares.

In general, the approval of any matter must occur through votes of shareholders attending a general meeting in person, or through a proxy, corresponding to at least the majority of the common shares represented at the meeting, and abstentions are not taken into account for this calculation. Nevertheless, the affirmative vote of shareholders representing at least one-half of the voting shares is needed for the approval of the following matters, among others: (i) reduction of the mandatory dividend to be distributed to our shareholders; (ii) changes in our business purpose; (iii) our merger, spin-off or consolidation; (iv) our participation in a corporate group (as defined by the Brazilian Corporate Law); (v) the termination of a state of liquidation; and (vi) our dissolution.

The CVM may authorize the aforementioned quorum, set forth in the Brazilian Corporate Law, to be reduced in the case of a publicly held company with widely held shares, and where the last three general meetings have been attended by shareholders representing less than half the voting shares.

**Call Notice of Our Shareholders' General Meetings**

The Brazilian Corporate Law requires all general meetings to be called by a minimum of three entries in a periodical of mass circulation in São Paulo, where the B3 is located. Our call notices for meetings are currently published in the *Valor Econômico* newspaper. The first call must be published not more than 30 days before the date of the meeting, and the second call not more than eight days in advance. However, in certain circumstances, at the request of any shareholder, the CVM may (i) after consulting us, require the shareholders' meeting to be postponed and held 30 days after the first call; and/or (ii) suspend for up to 15 days the advance notice required for an extraordinary general meeting, to give the shareholder time to understand and analyze the proposals to be voted on at the meeting. The call notices must give full details of the agenda for the meeting (the term "general matters" being prohibited) and the adequate supporting documents must be available to the public on the CVM's website from the date of publication of the first call.

Our shareholders' meetings are held at our headquarters at Avenida Presidente Juscelino Kubitschek, 2041, Suite 281, Block A, Condomínio WTORRE JK, Vila Nova Conceição, 04543-011, in the city of São Paulo, state of São Paulo, Federative Republic of Brazil. The Brazilian Corporate Law allows our shareholders to hold meetings outside our headquarters in an event of force majeure, provided that the meetings are held in the city of São Paulo and the relevant notice contains a clear indication of the place where the meeting will be held.

*[**Table of Contents**](#toc)*<br>

**Responsibility for Calling General Meetings**

It is usually the responsibility of our Board of Directors to call a general meeting, provided that such meetings may also be called by the following persons or bodies: (i) any shareholder, when our directors fail to call a meeting within 60 days of the date required by law or by our By-Laws; (ii) shareholders representing a minimum of 5% of our capital stock, if our managers fail to call a meeting, within eight days, in response to a justified request submitting matters to be discussed; (iii) shareholders representing a minimum of 5% of our capital stock, if our Board of Directors fails to call a meeting intended to install a Fiscal Council, within eight days of the request being made; and (iv) the Fiscal Council (if already installed), if our Board of Directors fails to call the annual general meeting; and (v) the Fiscal Council (if installed), whenever there are serious or urgent reasons.

**Conditions for Admission to General Shareholders' Meetings**

Shareholders attending general meetings must prove that they are the holders of shares with voting rights, as set forth in the Brazilian Corporate Law. Our shareholders may be represented by a proxy (including a public proxy in accordance with CVM Resolution No. 81, of March 29, 2022, as amended), appointed not more than one year before the date of the meeting, and this representative must be a shareholder, a manager, a lawyer or, in the case of a publicly held company, as ours is, a financial institution, Investment funds may be represented by their respective administrators.

**Remote Voting**

The CVM establishes rules for remote participation and voting in general meetings of publicly held companies.

Accordingly, we have put in place the necessary structure to allow our shareholders to participate and vote remotely at general meetings. For this purpose, our shareholders must follow the voting procedures disclosed by us in the call notice for the relevant general meeting to transfer the voting pronouncements including by contacting either us or the custodians (who will be responsible for transferring the voting pronouncements to us), pursuant to the terms of the applicable regulations.

**Policy on Trading in Our Own Securities**

The objective of our Policy on Trading in Our Own Securities, prepared in accordance with CVM Resolution No. 44 of August 23, 2021, or "CVM Resolution No. 44," is: (i) to control and punish those persons with access to privileged information and who use this information to trade in securities issued by us; and (ii) to establish rules for trading in our securities.

The purpose of this policy is to avoid insider trading (the furnishing of privileged information from which third parties may benefit) and to ensure transparency in the trading of our securities. Our trading policy establishes blackout periods for trading our shares by ourselves, our controlling shareholders (direct or indirect), members of the Board of Directors, Executive Officers and members of our Fiscal Council (when one has been installed) and other technical or consultative bodies or other persons who, by virtue of their job, position or commercial, professional or trust relationship with us, have access to any privileged information. This is intended to avoid improper use of information not disclosed by us.

Among other matters, persons subject to our policy shall refrain from buying or selling, by themselves through direct dependents or by using directly or indirectly controlled companies, any securities issued by us, or backed by them, as well as their respective derivatives, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) From the time when such persons become aware of material information that may affect the value of our
securities, until such information is disclosed to the public. Those subject to the policy may trade in Company securities received or
acquired under our variable compensation plans only during a period of 30 days from the date when such securities are vested, and after
the end of the corresponding lock-up period, for the purpose of disposing of them, subject to the undertakings described in the following
items;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) During the period between our decision to increase capital stock, issue securities, distribute dividends,
pay bonuses, or execute a stock split or a reverse stock split, and the publication of the corresponding notices or announcements;

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) When it is intended to carry out a takeover, a total or partial spin-off, transformation or corporate
re-organization; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) During the 30-day period prior to the publication of annual or six-monthly financial statements, or
quarterly financial information. However, exceptionally in the case of issues of fixed-rate securities by us by means of a public offer
overseas, in order to raise funds for us in the ordinary course of our business, including medium term notes issued by us, this period
shall be reduced to 15 days before the publication of such statements.

**Right to Withdrawal**

The Brazilian Corporate Law gives our shareholders the right to withdraw from Santander Brasil, upon reimbursement of the equity value of their shares, if the shareholder disagrees with or abstains from voting on certain resolutions approved in shareholders' general meetings.

According to the Brazilian Corporate Law, the right of withdrawal may be exercised in the following circumstances, among others as provided by law: (i) a change in the preferences, privileges or repayment or redemption conditions granted to our preferred shares, or the creation of a new, more favored class of shares (in which case, only a shareholder who is adversely affected by such change or creation shall have the right of withdrawal); (ii) spin-off (subject to the conditions below); (iii) a reduction in our mandatory dividend; (iv) a change in our corporate purpose; (v) a merger or incorporation with another company in specific circumstances (as described below); (vi) our joining to a group of companies, as defined in the Brazilian Corporate Law; (vii) a corporate transformation; (viii) the takeover of all of our shares by another Brazilian company, so as to make us its wholly owned subsidiary; or (ix) the acquisition of control of another company at a price exceeding the legal limits.

The Brazilian Corporate Law also provides that a spin-off of a company shall entitle its shareholders to withdraw only if it results in: (i) a change in the corporate purpose, unless the assets spun off are transferred to a company whose principal activity coincides with the business purpose of the spun-off company; (ii) a reduction in the mandatory dividend; or (iii) becoming part of a group of companies, as defined in the Brazilian Corporate Law. In addition, in the event of a consolidation or merger of us into another company, or when we become part of a group of companies (as defined in the Brazilian Corporate Law), our shareholders will not be entitled to withdraw from our company if the shares of such companies (a) are liquid, i.e., are listed on the three general indexes or on any other Stock Exchange index, as defined by the CVM, and (b) are widely held, such that our controlling shareholders or other companies under common control hold less than half the shares of the type or class to which the right of withdrawal corresponds. The right of withdrawal must be exercised within 30 days of publication of the minutes of the general meeting resolving on the matter that gave rise to such right. Furthermore, we have the right to reconsider any resolution that has given rise to a right of withdrawal, during the 10 days following the end of the period for exercising the right, if we consider that the payment of the price for buying out dissident shareholders would put our financial stability at risk.

Shareholders who exercise the right to withdrawal shall receive the equity value of their shares, based on the latest balance sheet approved at a general meeting. If, however, the resolution giving rise to the right of withdrawal was passed more than 60 days after the date of the latest approved balance sheet, a shareholder may call for a special balance sheet to be prepared as of a date not more than 60 days before the resolution, to assess the value of the shares. In this case, we must immediately pay 80% of the reimbursement value, calculated according to the latest balance sheet approved by our shareholders, and the balance within 120 days of the date of the resolution of the general meeting.

**Redemption of Shares**

According to the Brazilian Corporate Law, we may redeem our shares by means of a resolution passed at a general meeting by votes representing at least 50% of the shares affected by the redemption. Shares may be redeemed out of retained profits, revenues reserves or capital reserves. If not all of the shares are to be redeemed, a lottery ballot shall be held. If custody shares are selected in the ballot and the custody agreement does not provide for the situation, the financial institution must specify the proportion of shares to be redeemed.

*[**Table of Contents**](#toc)*<br>

**Preemptive Rights**

Our shareholders have preemptive rights to subscribe for shares in any capital increase, in proportion to their shareholding at the time of the increase. Our shareholders also have preemptive rights in any offer of our shares or subscription warrants. A period of not less than 30 days from the publication of the notice to shareholders of the capital increase is allowed for the exercise of preemptive rights, and these rights are transferable.

However, according to the Brazilian Corporate Law and our By-Laws, our shareholders do not have preemptive rights in cases of granting or exercise of any share call options (provided the share call option is granted by us in accordance with our By-Laws). In addition, our Board of Directors may exclude the preemptive right of our shareholders or reduce the exercise period, in the issuance of shares and subscription warrants whose placement is made through sale on stock exchange or public subscription, or share exchange, in a public offering of control acquisition.

**Purchase of Our Own Shares**

Our By-Laws authorize our Board of Directors to approve the purchase of our own shares. In any of the following circumstances, the decision will only become effective upon prior approval at a shareholders meeting: (i) acquisition on an organized securities market involving more than 5% of our outstanding shares of a certain type or class in less than 18 months; (ii) acquisition on an organized securities market for prices 10% above the market price; (iii) acquisition aiming at changing or preserving our share control composition or our management structure; or (iv) where the counterparty in an acquisition out of the organized securities markets is related to us (according to the applicable accounting rules). The decision to purchase our shares will be disclosed to the markets and the respective trade will be settled within 18 months from the approval.

The decision to acquire our shares is also subject to certain restrictions. It may not, among other things: (i) aim for the acquisition of shares belonging to our controlling shareholders; (ii) be carried out in the organized markets for prices above the market prices; (iii) take place simultaneously with a public offering for the purchase of our shares; or (iv) require the use of funds exceeding the available funds (considered all capital or profits reserves plus the realized results of the ongoing fiscal year, excluding, in both cases, the legal reserve, the reserve for realizable profits, the special reserve for non-distributed compulsory dividends and the tax incentives).

We may not hold in treasury more than 10% of our outstanding shares of a certain type or class, including shares held by our subsidiaries and affiliated companies and the shares corresponding to the economical exposure arising from derivatives or deferred settlement transactions entered into by us, our subsidiaries and affiliated companies. This limit does not apply to reimbursed shares, forfeited shares, or acquisitions in the scope of a public offering for acquisition of shares, which will be subject to specific laws and regulation.

We may purchase our shares on the stock exchange, but not for a price above the market value. Acquisitions by means of private transactions must observe the applicable limitations and the approval by the shareholders meeting may be required. We may also buy our own shares in the event that we should cease to be a publicly held company. We may also purchase or issue put or call options on our shares.

On February 2, 2021, our Board of Directors approved the unit buyback program to cover the acquisition, by us or our branch in the Cayman Islands, of up to 36,956,402 units or ADRs, representing 36,956,402 common shares and 36,956,402 preferred shares, corresponding to approximately 1% of the totality of our corporate capital.

The term of the buyback program is 18 months counted from September 26, 2025, expiring on March 26, 2027.

**Cancellation of Registration as a Publicly Held Company**

We may cancel our registration as a publicly held company and, for this purpose, our controlling shareholders must necessarily make a public offer to acquire all our shares in the market, according to the Brazilian Corporate Law and the regulations issued by the CVM. The minimum offer price must be at least equal to the economic value of our shares, as valued by a specialized company using any generally accepted and recognized valuation method, or any other criteria defined by the CVM.

The valuation report must be prepared by a specialized and experienced appraiser, who is independent of Santander Brasil, our management team and our controlling shareholders and who shall be chosen by the board of directors. The controlling shareholder shall bear the costs of preparing the valuation report.

**Disposal of Control**

Our By-Laws state that disposal of control of our company, either in a single transaction or in a series of transactions, must be subject to a condition precedent or a resolutory condition that the acquirer makes a public offer to acquire all the shares held by our other shareholders, both common and preferred. This is also compliant with the conditions and deadlines required by applicable law, ensuring that minority shareholders receive equal treatment with respect to the controlling shareholder in the disposal of control.

This public offer is also required (i) in cases where there is assignment for consideration of rights to subscribe for shares that may result in the disposal of the company's control; and (ii) in case of disposal of control of a company that holds the controlling power over us.

The disposal of control will also be subject to the prior authorization of the Brazilian Central Bank, pursuant to the terms and conditions of Central Bank Resolution No. 4,970/22. For additional information, please refer to "Item 4. Information on the Company—4B. Business Overview—Regulation and Supervision."

**Requirement for Disclosure of Information**

As a publicly held company, we must comply with the requirements for disclosure of information set forth by the Brazilian Corporate Law and the CVM.

**Periodic and Occasional Disclosure of Information**

The regulations applicable to publicly held companies issued by the CVM, including CVM Resolution No. 44, provide that we must disclose both periodic and occasional information.

We are also required to provide the CVM and B3 within the same time period the information related to the securities traded by us, our entities and affiliated companies.

**Disclosure of Information about Our Shareholders with Relevant Interest**

CVM Resolution No. 44 sets forth that (i) any direct or indirect controlling shareholders, (ii) any shareholders entitled to elect members of the board of directors and fiscal council, as well as (iii) any person or group of persons acting jointly with the aforementioned persons or representing the same interest, that carries out relevant transactions (that is, transactions whereby the direct or indirect holding of the aforementioned persons surpasses, upwards or downwards the thresholds of 5%, 10%, 15%, and so on successively, of our shares of a certain class and type) must disclose to us information on their trades, which will be sent to the CVM.

**10C. Material Contracts**

For the two years immediately preceding the publication of this annual report, we were not a party to any material contract outside the ordinary course of business.

**10D. Exchange Controls**

**Foreign Investment in Brazil**

***Foreign Direct Investment***

Foreign direct investment in Brazil is regulated by the New Foreign Exchange Law. A foreign direct investor under the New Foreign Exchange Law must:

&nbsp;&nbsp;&nbsp;&nbsp;• report his/her condition as a foreign direct investor with the Brazilian Central Bank;

&nbsp;&nbsp;&nbsp;&nbsp;• obtain a taxpayer identification number from the Brazilian tax authorities;

&nbsp;&nbsp;&nbsp;&nbsp;• appoint a tax representative in Brazil; and

&nbsp;&nbsp;&nbsp;&nbsp;• appoint a representative in Brazil for service of process in respect of suits based on the Brazilian
Corporate Law.

Foreign capital in amounts (per transaction) exceeding R$100 thousand must be reported to the Brazilian Central Bank through the Foreign Capital Information Reporting System – Foreign Direct Investment, or the "*Sistema de Prestação de Informações de Capital Estrangeiro – Investimento Estrangeiro Direto*," within 30 days of the flow of funds into Brazil in accordance with the New Foreign Exchange Law. The reporting of foreign capital (in amounts per transaction exceeding R$100 thousand) is required for the remittance of profits abroad, the repatriation of capital and the formalization of reinvestments. Investments will always be reported in the foreign currency in which they are made, or in Brazilian currency, if the funds are derived from a non-resident account properly held in Brazil.

Other than such reporting obligations, foreign investment is not subject to government approvals or authorizations and there are no requirements regarding minimum investment or local participation in capital (except in very limited cases such as in regard to financial institutions, insurance companies and other entities subject to specific regulations). Foreign participation, however, is limited (that is, subject to approvals) or forbidden in several sectors.

Foreign investments in currency must be officially channeled through financial institutions duly authorized to deal in foreign exchange. Foreign currency must be converted into Brazilian currency and vice versa through the execution of an exchange contract. Foreign investments may also be made through the contribution of assets and equipment intended for the local production of goods and services.

***Capital Markets Investment***

Investors residing outside Brazil, including institutional investors, are authorized to purchase securities in Brazil on the Brazilian stock exchange, provided that they comply with the registration requirements set forth in the applicable regulation enacted by CMN and the CVM.

Since January 1, 2025, portfolio investments have been regulated by Joint Resolution No. 13, which revoked the former rule (CMN Resolution No. 4,373, of March 30, 2015) which had been in force for about 10 years.

The main purpose of Joint Resolution No. 13 is to facilitate the entry of foreign investors in the Brazilian financial and capital markets. It introduced, among other things, the possibility for foreign investors of making investments in local currency with funds held in foreign bank accounts of the non-resident investor, or with bills of payment denominated in *reais* but issued abroad, without the need of converting these availabilities into portfolio investments by means of the execution of a simultaneous and symbolic foreign exchange transaction, which was previously required under CMN Resolution No. 4,373, as well as the possibility of the foreign investor making an investment directly from a nonresident checking or payment account in Brazilian *reais* opened with a local financial or payment institution. Reporting and local representation requirements applicable to this type of investment were also simplified.

With certain limited exceptions, under Joint Resolution No. 13 investors are permitted to carry out any type of transaction in the Brazilian capital markets involving a security traded on a stock or futures exchange or an organized over-the-counter market, but may not transfer the ownership of investments made under such regulation to other non-Brazilian holders through private transactions. Investments and remittances outside Brazil of gains, dividends, profits or other payments under Santander Brasil's shares are made through the commercial rate exchange market (assuming registration is required pursuant to the conditions and thresholds set forth in Joint Resolution No. 13 and the Brazilian Central Bank regulations governing foreign direct investments under the New Foreign Exchange Law).

*[**Table of Contents**](#toc)*<br>

Under Joint Resolution No. 13, the investment made by individuals or legal entities that are not resident in the financial market and in the securities market must comply with the following parameters:

&nbsp;&nbsp;&nbsp;&nbsp;• investments must be made using the same financial instruments and modalities available to investors
residing in Brazil;

&nbsp;&nbsp;&nbsp;&nbsp;• non-resident investors will be subject to the same registration requirements and operational limits
applicable to residents;

&nbsp;&nbsp;&nbsp;&nbsp;• it will be necessary to respect any restrictions applicable to the trading environment, as well as other
provisions expressly provided for in the current regulations;

&nbsp;&nbsp;&nbsp;&nbsp;• the non-resident investor must constitute a representative in Brazil for Brazilian Central Bank and
CVM purposes, except if the investment observes the following conditions, which exempt the investor from constituting said representative:
(a) investments by non-resident natural persons (a.i) in financial assets, in any amount, when made from a nonresident checking or payment
account denominated in Brazilian *reais* opened with a Brazilian financial or payment institution; (a.ii) in securities, in any amount,
when made from a nonresident checking or payment account denominated in Brazilian *reais* opened with a Brazilian financial or payment
institution; (a.iii) in financial assets, in up to R$2 million, when made from overseas remittances through the execution of a foreign
exchange transaction; and (a.iv) in securities, in any amount, when made from overseas remittances through the execution of a foreign
exchange transaction; and (b) investments by legal entities in financial assets, in any amount, when made from a nonresident checking
or payment account denominated in Brazilian *reais* opened with a Brazilian financial or payment institution;

&nbsp;&nbsp;&nbsp;&nbsp;• non-resident investors (other than those who are natural persons, except in the cases when the natural
person invests over R$2 million in financial assets from overseas remittances through the execution of a foreign exchange transaction)
must obtain registration as a non-resident investor with the CVM;

&nbsp;&nbsp;&nbsp;&nbsp;• the non-resident investor must appoint a tax representative in Brazil; and

&nbsp;&nbsp;&nbsp;&nbsp;• the non-resident investor must obtain a taxpayer identification number from the Brazilian
federal tax authorities.

Securities and other financial assets held by foreign investors pursuant to said regulation must, according to their nature: (i) be booked by a financial institution or by an entity authorized to carry out the bookkeeping of financial assets or securities, duly accredited by the Brazilian Central Bank or the CVM, subject to the respective regulatory spheres of authority; (ii) be in the custody of a financial institution or entity authorized to provide such service, in accordance with the provisions of the Brazilian Central Bank or the CVM, according to their respective spheres of authority; (iii) be registered in a registration system operated by an entity authorized by the Brazilian Central Bank or the CVM for the purposes of carrying out the activity of registration of financial assets or securities, in accordance with the provisions of the Brazilian Central Bank or the CVM, according to their respective spheres of authority; (iv) be deposited in a centralized deposit system, managed by a central depositary authorized to carry out this activity, under the terms established by the Brazilian Central Bank and the CVM, according to their respective spheres of authority; and (v) be held in a deposit or prepaid payment account, in a financial or payment institution authorized by the Brazilian Central Bank, or in a registration account, as provided for in article 12 of CMN Resolution No. 5,008, of March 24, 2022.

CVM Resolution No. 13, of November 11, 2020 establishes the obligation of the representatives of investors residing outside Brazil to inform the CVM of the movements and applications of funds of such investors participating in collective accounts and holders of own accounts represented by them.

**10E. Taxation**

The following summary contains a description of certain Brazilian and U.S. federal income tax consequences of the ownership and disposition of units or ADRs, but it does not purport to be a comprehensive description of all the tax considerations that may be relevant to the ownership or disposition of units or ADRs. The summary is based on the tax laws of Brazil and regulations thereunder and on the tax laws of the United States and regulations thereunder, as of the date hereof, which are subject to change.

*[**Table of Contents**](#toc)*<br>

Although there is at present no income tax treaty between Brazil and the United States, the tax authorities of the two countries have had discussions that may culminate in a treaty. No assurance can be given, however, as to whether or when a treaty will enter into force or how it will affect the U.S. Holders (as defined below) of units or ADRs. Prospective holders of units or ADRs should consult their tax advisors as to the tax consequences of the acquisition, ownership, and disposition of units or ADRs in their particular circumstances.

***Brazilian Tax Considerations***

The following discussion is a summary of the Brazilian tax considerations relating to the acquisition, exchange, ownership, and disposition of units or ADRs by a Non-Resident Holder. The discussion is based on Brazilian law as currently in effect, which is subject to change, possibly with retroactive effect, and to differences of interpretation. Any change in such law may change the consequences described below.

The tax consequences described below do not consider the effects of any tax treaties or reciprocity of tax treatment entered into by Brazil and other countries. The discussion also does not address any tax consequences under the tax laws of any state or locality of Brazil.

The description below is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, exchange, ownership, and disposition of our units or ADRs. Holders of units or ADRs and prospective purchasers thereof should consult their tax advisors with respect to the tax consequences of owning and disposing of our units or ADRs in light of their particular investment circumstances.

***Transfer Price***

On December 12, 2022, Provisional Measure No. 1152/2022 was published. This measure amended the law relating to IRPJ and CSLL to address transfer pricing rules, thereby aligning Brazil with the guidelines principles of the Organization for Economic Co-operation and Development (OECD).

On June 15, 2023, Law No. 14,596/2023 was published, which was the result of this measure being converted into a law.

Among the matters addressed in this law, we highlight: (i) the formalization and the effects of opting to apply these rules; (ii) the definition of certain terms, such as "arm's length principle," "spontaneous adjustments," "compensatory adjustments" and "primary adjustment"; (iii) adjustments to the calculation bases of the IRPJ and CSLL; and (iv) rules on deductions of royalties, technical, scientific, administrative or any similar assistance. Law No. 14,596/2023 came into effect on January 1, 2024, as regulated by Brazilian Federal Revenue Service Normative Instructions no. 2,132/2023 and 2,161/2023.

***Pillar 2***

On October 3, 2024, the Brazilian government published Provisional Measure No. 1,262 ("Provisional Measure No. 1,262/24"), which incorporates the model rules established by the OECD to promote a global corporate income tax reform. This measure introduces an additional 15% CSLL rate for companies that are part of multinational groups with annual revenues exceeding 750 million euros, subject to a minimum effective tax rate on profits earned in Brazil. On the same day, the RFB issued Normative Ruling No. 2,228 ("IN 2,228/24"), providing further regulations on Provisional Measure No. 1,262/24.

This proposal aligns with OECD's Qualified Domestic Minimum Top-up Tax, which prioritizes the jurisdiction where the profits were originated when imposing a minimum income tax. If the minimum tax is not collected in Brazil, other jurisdictions may claim it on profits generated in the country. Provisional Measure No. 1,262/24 follows the OECD model to ensure that the additional CSLL paid in Brazil can be offset against the top-up tax that may be imposed by other jurisdictions. All entities whose results are consolidated into the financial statements of multinational groups, i.e., groups operating in more than one jurisdiction with annual revenues exceeding 750 million euros in two of the past four consecutive fiscal years, will be subject to the additional CSLL. This additional tax only applies to "excess" profits, defined as profits calculated according to Brazilian accounting standards (with certain adjustments) minus the so-called substance-based profits. The exclusion of substance-based profits aims to reduce the tax burden on results generated from operations intensive in tangible assets and labor.

*[**Table of Contents**](#toc)*<br>

The rules set forth in Provisional Measure No. 1,262/24 were subsequently incorporated into Law No. 15,078, of December 27, 2024 ("Law No. 15,078/24"), which was approved by the Brazilian National Congress and is currently in force. In this context, Law No. 14,467, of November 16, 2022, as amended by Law No. 15,078/24, now provides that losses ascertained as of January 1, 2025, related to credits that were in default as of December 31, 2024, which had not been deducted up to that date and had not been recovered, may only be excluded from net income for purposes of determining the taxable income (*lucro real*) and the CSLL tax base, at a rate of 1/84 per month, as from January 2026 (Article 6). Additionally, the legislation allows the institutions covered by the law to elect, by December 31, 2025, on an irrevocable and irreversible basis, to deduct such losses at a rate of 1/120 per month, also as from January 2026 (Article 6, paragraph 1). The statute further provides that such institutions are prohibited from deducting, in the 2025 tax year, losses incurred in an amount exceeding the taxable income for the year, prior to taking such deduction into account (Article 6, paragraph 2). Any losses that cannot be deducted as a result of this limitation must be added to the balance of losses subject to the installment deduction regime and excluded from net income at the same rate and over the same period, in accordance with the option elected by the institution (Article 6, paragraph 3). In light of these provisions, the legislation allows companies, as from January 2026, to begin using deductions related to the allowance for doubtful accounts (*Provisão para Devedores Duvidosos – PDD*) for purposes of recognizing deferred tax assets (DTA), subject to the conditions, limits, and timeframes set forth in Article 6 of Law No. 14,467/22, as amended.

**Income Tax**

**Dividends**

As from January 2026, as a general rule, dividends paid by a Brazilian company, such as ourselves, including stock dividends to a Non-Resident Holder are currently subject to withholding income tax at a 10% tax rate in Brazil. However, the following situations are exempt from WHT on the payment of dividends to nonresidents:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dividends related to results accrued up to the 2025 calendar year, provided that their distribution has been approved by December
31, 2025 and paid through 2028;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dividends paid to foreign governments that grant reciprocity in relation to the Brazilian government; dividends paid to sovereign
wealth funds; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• dividends paid to foreign entities whose main activity is the administration of pension and retirement benefit plans, pursuant to
regulations.

A tax credit shall be granted when the sum of the effective IRPJ and CSL rates of the distributing company, added to the 10% WHT rate, results in taxation exceeding the applicable nominal rate. This credit shall be calculated on the amount of profits and dividends effectively subject to the 10% WHT. The nonresident recipient should be allowed to claim the credit within 360 days from the end of each fiscal year.

**Interest Attributable to Shareholders' Equity**

Law 9,249, dated December 1995, as amended, allows a Brazilian corporation, such as ourselves, to make distributions to shareholders of interest on net equity and to treat those payments as a deductible expense for purposes of calculating Brazilian corporate income tax and social contribution on net profits, subject to the limits described below. These distributions may be paid in cash. For tax purposes, this interest is limited to the daily pro rata variation of the Long-Term Rate (*Taxa de Longo Prazo – TLP*), as determined by the Brazilian Central Bank from time to time, and the amount of this deductible expense may not exceed the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;• 50% of the net income (after the deduction of social contribution on net profit but before taking into
account allowances for income tax and the interest attributable to shareholders' equity) for the period in respect of which the
payment is made; and

&nbsp;&nbsp;&nbsp;&nbsp;• 50% of our accumulated profits.

As from January 2026, payment of interest on shareholders' equity to a Non-Resident Holder is subject to withholding income tax at the rate of 17.5%, or 25% for individuals or entities residing in a "Tax Haven." According to Brazilian legislation, a "Tax Haven" jurisdiction is one in which there is no income taxation or where the local income tax rate is generally applied at rates under 17%, following the issuance of Law No. 14,596/2023, or where local legislation imposes restrictions on disclosure regarding shareholder composition or investment ownership. These payments may be included, at their net value, as part of any mandatory dividend, as discussed above under "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividend Policy." Distributions of interest on shareholders' equity to Non-Resident Holders may be converted into U.S. dollars and remitted outside Brazil, subject to applicable exchange controls, if the investment is registered with the Brazilian Central Bank.

**Capital Gains**

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Taxation of Capital Gain Earned in the Country in a Transaction Not Carried Out on the Brazilian Stock Exchange (Or Similar Exchange)*** 

According to Law No. 10,833/03, the gains recognized on a disposition of assets located in Brazil, such as our units, by a Non-Resident Holder, could be subject to withholding tax in Brazil. This rule is applicable regardless of whether the disposition occurs in Brazil or abroad and regardless of whether the disposition is made to an individual or entity resident or domiciled in Brazil.

As a general rule, capital gains realized as a result of a disposition of units are the positive difference between the amount realized on the disposition of the units and the acquisition cost of such units.

Historically, the income tax on these gains had to be withheld at source and the tax rate would vary depending on the domicile of the Non-Resident Holder:

&nbsp;&nbsp;&nbsp;&nbsp;• If the Non-Resident Holder is not located in a Tax Haven, a progressive tax rate will be applied as
provided for in Law No. 13,259/16, as follows: (i) at a rate of 15% for the portion of the gain up to R$5 million, (ii) at a rate of 17.5%
for the portion of the gain that exceeds R$5 million but does not exceed R$10 million, (iii) at a rate of 20% for the portion of the gain
that exceeds R$10 million but does not exceed R$30 million, and (iv) 22.5% for the portion of the gain that exceeds R$30 million; and

&nbsp;&nbsp;&nbsp;&nbsp;• If the Non-Resident Holder is located in a Tax Haven, the tax rate will be 25%.

The tax must be withheld and paid by the buyer or, in cases where the buyer and seller are domiciled abroad, a legal representative of buyer shall be designated for the payment of the tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Taxation of the Capital Gains Earned in the Country in a Transaction Carried Out on the Brazilian Stock Exchange (Or Similar Exchange)*** 

There could also be the levy of income tax on net gains earned by a Non-Resident Holder on the disposition of units sold on the Brazilian stock exchange, commodities or futures exchange (or similar exchange). The tax rate will vary according to the type of investment registration made by the Non-Resident Holder at the Brazilian Central Bank, as well as the location of the beneficiary:

Capital gains earned by a Non-Resident Holder who (i) has its investment registered in Brazil with the Brazilian Central Bank under the rules of Joint Resolution No. 13, or "Registered Holder," and (ii) is not a Tax Haven resident are exempt from income tax; and

Capital gains earned by a Non-Resident Holder who is not a Registered Holder or is a Tax Haven resident (Registered Holder or not) are currently subject to income tax at a rate of 15%. In this case, withholding income tax of 0.005% will be levied by the intermediary institution (that is, a broker) that receives the order directly from the Non-Resident Holder, which can be later offset against the 15% income tax due on the capital gain, which will be paid by the Non-Resident Holder's tax representative in Brazil.

Any other gains realized on a disposition of units that is not carried out in an exchange environment or that is conducted in the non-organized "OTC market" are subject to the same rules set forth in item "(i) Taxation of Capital Gain Earned in the Country in a Transaction Not Carried Out on the Brazilian Stock Exchange (or Similar Exchange)." Gains realized by a Non-Resident Holder on the disposition of preemptive rights held in stock will be subject to Brazilian income tax, according to the same rules applicable to the sale of units or ADRs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(iii)***  ***Capital Reduction*** 

In case of a capital reduction by a Brazilian corporation, such as ourselves, the positive difference between the amount received by the Non-Resident Holder and the acquisition cost of the shares is treated as capital gain derived from a transaction held out of a Brazilian exchange described above in (i) and is therefore currently subject to withholding tax at the following progressive rates: (i) 15% for the portion of the gains up to R$5 million, (ii) 17.5% for the portion of the gain that exceeds R$5 million but does not exceed R$10 million, (iii) 20% for the portion of the gain that exceeds R$10 million but does not exceed R$30 million, and (iv) 22.5% for the portion of the gain that exceeds R$30 million for a Non-Resident Holder not located in a Tax Haven or up to 25% for a Non-Resident Holder located in a Tax Haven.

*[**Table of Contents**](#toc)*<br>

Although subject to interpretation, in the case of Non-Resident Holders carrying out investments pursuant to Joint Resolution No. 13, it is possible to sustain that the income tax should not apply at progressive rates under Law No. 13,259/16, but at a fixed rate of 15%. Moreover, Non-Resident Holders located in a Tax Haven jurisdiction are subject to a specific tax regulation and remain taxed to a tax rate of 25%.

**Sale of ADRs**

Pursuant to Section 26 of Law No. 10,833/2003, the sale of an asset located in Brazil by a Non-Resident Holder, whether to a Brazilian resident or to another Non-Resident Holder, is subject to Brazilian income tax. Our understanding is that ADRs do not qualify as assets located in Brazil and thus should not be subject to the Brazilian income tax. Notwithstanding the foregoing, since the tax rule referred to in Section 26 of Law No. 10,833 provides broad language and has not been definitely analyzed by the administrative or judicial courts, we are unable to assure you of the final outcome of such discussion.

**Gains on the Exchange of ADRs for Units**

Non-Resident Holders may exchange ADRs for the underlying units, sell the units on the Brazilian stock exchange and the sale proceeds may be remitted abroad. As a general rule, the exchange of ADRs for shares is not subject to income taxation in Brazil.

Upon receipt of the underlying units in exchange for ADRs, Non-Resident Holders may also elect to register with the Brazilian Central Bank the U.S. dollar value of such units as a foreign portfolio investment under Joint Resolution No. 13, which will entitle them to the tax treatment applicable to Registered Holders described above.

Alternatively, the Non-Resident Holder is also entitled to register with the Brazilian Central Bank the U.S. dollar value of such units as a foreign direct investment under the New Foreign Exchange Law, in which case the respective sale would be subject to the tax treatment applicable to transactions carried out of by a Non-Resident Holder that is not a Registered Holder.

**Gains on the Exchange of Units for ADRs**

The deposit of units in exchange for ADRs by a Non-Resident Holder may be subject to Brazilian income tax on capital gains if the acquisition cost of the units is lower than the market price for such units.

The difference between the acquisition cost and the average price of the units is considered a capital gain currently subject to income tax at the following progressive rates: (i) 15% for the portion of the gains up to R$5 million, (ii) 17.5% for the portion of the gain that exceeds R$5 million but does not exceed R$10 million, (iii) 20% for the portion of the gain that exceeds R$10 million but does not exceed R$30 million, and (iv) 22.5% for the portion of the gain that exceeds R$30 million), or 25.0% for Tax Haven residents. If a Non-Resident Holder that is a foreign direct investor under the New Foreign Exchange Law wishes to deposit its units into the ADR program in exchange for ADRs, such Non-Resident Holder will be required to present to the custodian evidence, if applicable, of payment of the income tax assessed on capital gains at the aforementioned progressive rates or, in the case of a Tax Haven resident, 25%.

The progressive rates of Law No. 13,259/16 to capital gains obtained by Non-Resident Holders not located in a Tax Haven will be applicable and for Non-Resident Holders (whether they are considered to be Non-Resident Holders as a result of Joint Resolution No. 13 or otherwise) located in a Tax Haven are subject to a specific tax regulation and remain taxed to a tax rate of 25%.

However, in certain circumstances, there may be arguments to sustain the position that such taxation is not applicable to Joint Resolution No. 13 Holders that invest in Brazil observing the conditions of Joint Resolution No. 13 and that are not resident or domiciled in a Low or Nil Tax Jurisdiction, which should be subject to the assessment of the withholding income tax at a fixed 15% rate.

Moreover, there are arguments to support the position that there should be no withholding tax on this transaction, because: (i) the deposit of units would not have represented the disposal of the investment; and (ii) the transaction is registered on the stock exchange. Given the uncertainty of these two positions, we recommend that you consult your tax advisors. Please note, however, that the RFB already took the position that the deposit of Shares in exchange for ADRs should be viewed as a taxable transaction in Brazil, following Cosit Tax Ruling No. 292, of December 17, 2024.

***Tax on Foreign Exchange Transactions (IOF/Exchange)***

The IOF on Exchange Transactions, or "IOF/Exchange," is due on the conversion of Brazilian or foreign currency, or any document that represents it, into an available equivalent amount. Currently, for most foreign exchange transactions, the IOF/Exchange rate is 3.5%. However, foreign exchange transactions carried out in connection with investments made by Non-Resident Holders in the Brazilian financial and capital markets under Joint Resolution No. 13 are generally subject to the IOF/Exchange at a rate of zero. The Brazilian government may increase any of these rates at any time, up to 25%. However, any increase in rates would only apply to future transactions.

***Tax on Transactions Involving Bonds and Securities and Derivatives***

Brazilian law imposes IOF tax on Transactions Involving Bonds and Securities, or "IOF/Bonds." Currently, the IOF Bonds tax is due at a daily rate of 1.0%, limited to 96.0% of the income generated by fixed income bonds, on the redemption amount or the amount received from assignment or renegotiation. The rate is reduced to zero as from the thirtieth day. The rate of IOF/Bonds tax applicable to transactions of derivatives and variable income securities, including those traded in stock, commodities or futures markets that involve shares, or units composed of shares, is reduced to zero.

**Other Brazilian Taxes**

The inheritance and gift tax (Imposto sobre Transmissão Causa Mortis e Doação de Quaisquer Bens ou Direitos), or "ITCMD," as regulated by Complementary Law No. 227/2026, is applicable to the transfer of any goods or rights by gift or bequest. The transfer of shares, or units comprised of shares, that are abroad to individuals who are resident in Brazil is subject to taxation. The ITCMD is a state-level tax, with progressive rates depending on the transferred share, and a maximum rate capped by the Brazilian Federal Senate at 8%. Each Brazilian state must enact its own legislation regulating the progressivity of the applicable rates.

**Material U.S. Federal Income Tax Considerations for U.S. Holders**

The following summary describes the material U.S. federal income tax consequences of the ownership and disposition of ADRs or units, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person's decision to acquire such securities. This summary does not address "Medicare contribution tax" consequences and applies only to U.S. Holders (as defined below) that hold ADRs or units as capital assets for U.S. federal income tax purposes and does not address special classes of holders, such as:

&nbsp;&nbsp;&nbsp;&nbsp;i. certain financial institutions;

&nbsp;&nbsp;&nbsp;&nbsp;ii. insurance companies;

&nbsp;&nbsp;&nbsp;&nbsp;iii. dealers and traders in securities that use a mark-to-market method of tax accounting;

&nbsp;&nbsp;&nbsp;&nbsp;iv. persons holding ADRs or units as part of a hedge, "straddle," conversion transaction
or integrated transaction;

&nbsp;&nbsp;&nbsp;&nbsp;v. holders whose "functional currency" is not the U.S. dollar;

&nbsp;&nbsp;&nbsp;&nbsp;vi. holders liable for any minimum tax;

&nbsp;&nbsp;&nbsp;&nbsp;vii. tax exempt entities, including "individual retirement accounts" and "Roth
IRAs";

&nbsp;&nbsp;&nbsp;&nbsp;viii. partnerships or other entities classified as partnerships for U.S. federal income tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;ix. holders that own or are deemed to own 10% or more of our shares by vote or value;

&nbsp;&nbsp;&nbsp;&nbsp;x. persons holding ADRs or units in connection with a trade or business conducted outside the
United States; and

&nbsp;&nbsp;&nbsp;&nbsp;xi. persons who acquired ADRs or units pursuant to the exercise of an employee stock option or
otherwise as compensation.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds units or ADRs, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and upon the activities of the partnership, Partnerships holding units or ADRs and partners in such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences of holding and disposing of the units or ADRs.

*[**Table of Contents**](#toc)*<br>

The summary is based upon the Internal Revenue Code of 1986, as amended, or the "Code" administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, all as of the date hereof, changes to any of which may affect the tax consequences described herein, possibly with retroactive effect. In addition, the summary is based in part on representations of the depositary and assumes that each obligation provided for in, or otherwise contemplated by, the deposit agreement or any other related document will be performed in accordance with its terms. U.S. Holders are urged to consult their tax advisors as to the U.S. federal income tax consequences of the acquisition, ownership and disposition of ADRs or units in their particular circumstances.

As used herein, a "U.S. Holder" is, for U.S. federal income tax purposes, a beneficial owner of ADRs or units that is:

&nbsp;&nbsp;&nbsp;&nbsp;(1) an individual who is a citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;(2) a corporation, or other entity taxable as a corporation, created or organized in or under the laws of
the United States, any state thereof or the District of Columbia;

&nbsp;&nbsp;&nbsp;&nbsp;(3) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;(4) a trust if (a) a court within the United States is able to exercise primary supervision for the administration
of the trust, and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (b) the trust has
validly elected under applicable Treasury Regulations to be treated as a U.S. person.

In general, for U.S. federal income tax purposes, U.S. Holders of ADRs will be treated as the owners of the underlying units represented by those ADRs. Accordingly, no gain or loss will be recognized if a U.S. Holder exchanges ADRs for the underlying units represented by those ADRs.

**Taxation of Distributions**

Distributions paid on our units or ADRs (including distributions to shareholders that are treated as interest on net equity for Brazilian tax purposes and amounts withheld in respect of Brazilian tax), other than certain pro rata distributions of our common shares, will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends. These dividends will be included in a U.S. Holder's income on the date of the U.S. Holder's (or in the case of ADRs, the depositary's) receipt of the dividend, and will not be eligible for the "dividends received deduction" generally allowed to corporations receiving dividends from domestic corporations under the Code. The amount of the distribution will equal the U.S. dollar value of the *reais* received, calculated by reference to the exchange rate in effect on the date that distribution is received (which, for U.S. Holders of ADRs, will be the date on which the distribution is received by the depositary), whether or not the depositary or U.S. Holder in fact converts any *reais* received into U.S. dollars at that time. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder generally will not be required to recognize foreign currency gain or loss in respect of the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt. Any gains or losses resulting from the conversion of *reais* into U.S. dollars will be treated as ordinary income or loss, as the case may be, of the U.S. Holder and will generally be U.S. source.

Subject to applicable limitations (including the requirement that the ADRs be readily tradable on an established securities market in the United States) and the discussion of the passive foreign investment company rules below, under current law, dividends paid with respect to our ADRs to certain non-corporate U.S. Holders will be taxable at the preferential rates applicable to long-term capital gain. Non-corporate U.S. Holders should consult their tax advisors regarding the availability of these favorable rates in their particular circumstances.

**Sale or Other Disposition of ADRs or Units**

Subject to the discussion of the passive foreign investment company rules below, gain or loss realized by a U.S. Holder on the sale or exchange of ADRs or units will be subject to U.S. federal income tax as capital gain or loss in an amount equal to the difference between the U.S. Holder's adjusted tax basis in the ADRs or units and the amount realized on the disposition, in each case as determined in U.S. dollars. Such gain or loss will be long-term capital gain or loss to the extent that the U.S. Holder's holding period with respect to the ADRs or units exceeds one year. Gain or loss, if any, will generally be U.S. source for foreign tax credit purposes. The deductibility of capital losses is subject to limitations. Long-term capital gain of a non-corporate U.S. Holder is generally taxed at preferential rates. If a Brazilian tax is withheld on the sale or other disposition of ADRs or units, a U.S. Holder's amount realized will include the gross amount of proceeds of the sale or disposition before the deduction of the Brazilian tax. See "—Brazilian Tax Considerations" for a description of when a disposition may be subject to taxation by Brazil.

*[**Table of Contents**](#toc)*<br>

**Foreign Tax Credits**

Subject to certain generally applicable limitations, which may vary depending upon a U.S. Holder's circumstances, a U.S. Holder might be entitled to a credit against its U.S. federal income tax liability for Brazilian income taxes withheld from dividends on ADRs or units. On December 28, 2021, certain Treasury Regulations pertaining to foreign tax credits (the "Final Treasury Regulations") were released that impose significant new limitations on the non-U.S. taxes (including withholding taxes) for which a foreign tax credit can be claimed. Corrections with respect to the Final Treasury Regulations were published on July 27, 2022. However, the IRS has released notices that indicate that the U.S. Treasury Department and the IRS are considering amendments to the Final Treasury Regulations and provides relief from certain provisions of the Final Treasury Regulations for taxable years ending before the date that a notice or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other guidance). The rules governing foreign tax credits are complex, and U.S. Holders should therefore consult their tax advisors as to the availability of foreign tax credits for any amounts withheld with respect to dividends on ADRs or units. A U.S. Holder will be entitled to use these foreign tax credits to offset only the portion of its U.S. tax liability that is attributable to foreign-source income. This limitation on foreign taxes eligible for credit is calculated separately with regard to specific classes of income. In addition, a U.S. Holder must satisfy minimum holding period requirements in order to be eligible to claim a foreign tax credit for foreign taxes withheld on dividends.

Instead of claiming foreign tax credits, a U.S. Holder may, at its election, deduct such Brazilian income taxes in computing taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all foreign taxes paid or accrued in the taxable year.

The Brazilian IOF/Exchange Tax imposed on the purchase of units and the IOF/Bonds Tax on the deposit of units in exchange for ADRs (as discussed above under "—Brazilian Tax Considerations") will not be treated as creditable foreign tax for U.S. federal income tax purposes. U.S. Holders should consult their tax advisors as to whether those taxes would be deductible for U.S. federal income tax purposes.

The rules governing foreign tax credits are complex and, therefore, U.S. Holders are urged to consult their own tax advisors to determine whether they are subject to any special rules that limit their ability to make effective use of foreign tax credits.

**Passive Foreign Investment Company Rules**

Based on proposed Treasury Regulations, including regulations which are proposed to be effective for taxable years beginning after December 31, 1994 (and on which taxpayers may currently rely pending finalization), we believe we were not a passive foreign investment company (a "PFIC") for our taxable year ended December 31, 2025. However, because the proposed Treasury Regulations may not be finalized in their current form, because the application of the proposed regulations is not entirely clear and because the composition of our income and assets will vary over time, there can be no assurance that we will not be a PFIC for any taxable year. The determination of whether we are a PFIC is made annually and is based upon the composition of our income and assets (including, among others, entities in which we hold at least a 25.0% interest), and the nature of our activities.

If we were a PFIC for any taxable year during which a U.S. Holder held our ADRs or units, any gain recognized by a U.S. Holder on a sale or other disposition of ADRs or units would be allocated ratably over the U.S. Holder's holding period for the ADRs or units. The amounts allocated to the taxable year of the sale or other exchange and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to all other taxable years would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the resulting tax liability for each of those taxable years. Further, the portion of any distribution in respect of ADRs or units that is in excess of 125% of the average of the annual distributions on ADRs or units received by the U.S. Holder during the preceding three years or the U.S. Holder's holding period, whichever is shorter, would be subject to taxation as described above. Certain elections may be available that would result in alternative treatments (such as mark-to-market treatment) of the ADRs or units, U.S. Holders should consult their tax advisors to determine whether any of these elections would be available and, if so, what the consequences of the alternative treatments would be in their particular circumstances.

*[**Table of Contents**](#toc)*<br>

If we were to be treated as a PFIC in any taxable year in which a U.S. Holder held units or ADRs, a U.S. Holder would generally be required to file IRS Form 8621 with its annual U.S. federal income tax returns, subject to certain exceptions.

In addition, if we were to be treated as a PFIC in a taxable year in which we pay a dividend or the prior taxable year, the preferential dividend rates discussed above with respect to certain dividends paid to non-corporate holders would not apply.

**Information Reporting and Backup Withholding**

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding unless (i) the U.S. Holder is an exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder's U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Certain U.S. Holders who are individuals (and specified entities that are formed or availed of for purposes of holding certain foreign financial assets) may be required to report information relating to their ownership of an interest in certain foreign financial assets, including stock of a non-U.S. entity, subject to certain exceptions (including an exception for publicly traded stock and interests held in custodial accounts maintained by a U.S. financial institution). U.S. Holders are urged to consult their tax advisors regarding the effect, if any, of this requirement on the ownership and disposition of ADRs or units.

**FATCA**

The United States has enacted legislation, commonly referred to as "FATCA," that generally imposes a reporting and withholding regime with respect to certain U.S. source payments (including interest and dividends), and to payments of gross proceeds from the disposition of property that can produce U.S. source interest and dividends and certain payments made by entities that are classified as financial institutions under FATCA. However, regulations proposed in 2018 (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization) eliminate the withholding requirement on payments of gross proceeds of a taxable disposition. The United States has entered into an intergovernmental agreement regarding the implementation of FATCA with Brazil, or the "IGA." For further information, see "Item 4. Information on the Company—B. Business Overview—Regulation and Supervision—Other Applicable Laws and Regulations—FATCA," above. Under the current terms and conditions of the IGA, we do not expect payments made on or with respect to the ADRs or units to be subject to withholding under FATCA. However, significant aspects of when and how FATCA will apply remain unclear, and no assurance can be given that withholding under FATCA will not become relevant with respect to payments made on or with respect to the ADRs or units in the future. Prospective investors should consult their own tax advisors regarding the potential application of FATCA.

**ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

**Overview**

In addition to establishing and applying our local risk management policies and procedures, we have incorporated the Santander Group's global risk management functions at various levels of our organization, including financial, credit, market, operational and compliance risk, to ensure a consistent approach worldwide.

In addition, committees led by senior management are responsible for controlling risks by overseeing credit approval and compliance with the exposure policies defined and approved by the Bank's board of directors.

The Control department and Risk Consolidation department provided their respective Risk management reports to senior management. Likewise, the reports for senior management of the Santander Group's financial entities and foreign branches are generated mainly by the risk control departments of each of those entities and branches.

The presentation of such information to senior management is designed to enhance the understanding and management of risks for the Santander Group's administrative bodies and branches. The type of information and highlights in each report varies depending on the intended audiences within senior management, such as the Santander Group, its financial entities, or its foreign branches. Information can be transmitted to senior management through our intranet risk reporting tool, by e-mail or through live presentations.

Information, analyses and decisions are also disseminated through the channels described below, fostering communication among all areas of the organization:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. internal department mailboxes, which allow for the exchange of information within groups
and areas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. periodic meetings (departmental, monthly, quarterly, off-site, conventions), which allow
for regular exchange of information on an in-person basis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. our regulations portal, which is an internal portal within our intranet where we maintain
our current risk management policies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. e-mail;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v. video and teleconferences with Santander Spain; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vi. risk committees, including the executive risk committee for Brazil and the risk control committee.

Information is prepared with the goal of improving risk management and is classified into two groups:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. Standard information: this information is generated on a regular basis and with fixed content,
subject to revision, made available to senior management for select target areas, depending on the type of information included in the
report. The reports are used to facilitate knowledge about the risk for which the Risk Management department is responsible, including
credit use, instrument valuation and results, as well as the analyses needed to manage these risks and optimize capital.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Non-standard information: this includes presentations and information not included in the
reports above prepared for our senior management on an ad hoc basis or upon specific request. When the request for certain information
becomes more regular, such reporting is integrated into automated "Standard information."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. Each report varied by the nature of the information and its frequency. The nature of the
information provided is either quantitative or qualitative.

*Quantitative Information*. Quantitative information includes risk metrics that permit our senior management to better analyze situations, trends and developments in each segment, activity or portfolio, relating to planned scenarios or defined limits, with emphasis on any scenarios falling outside such limits. Quantitative information primarily addressed the liquidity and market risk (trading and banking book) which includes, among other items, measurements of positions, mark-to-market valuations, sensitivity analyses, volume analyses, measures of liquidity gaps and country risk models, impacts of risks on results, economic risks, stress test simulations and back-testing.

*[**Table of Contents**](#toc)*<br>

*Qualitative Information*. Qualitative information includes internal and external events relating to the economic, financial or competitive environment, and an evaluation and analysis of the causes and known or foreseeable consequences of such events. These also include measures used to prepare such models.

The frequency with which quantitative and qualitative risk management information is prepared depends on the information provided, as follows:

***Daily information:***

&nbsp;&nbsp;&nbsp;&nbsp;i.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; liquidity and market risk: includes data on treasury limits (VaR, positions, sensitivity of linear and nonlinear econometric models) and the principal changes in the treasury portfolio. Also includes short-term liquidity and liquidity buffer calculation.

***Weekly information:***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. focuses on generating updated high-level information in different segments (focused on solvency
risk) or portfolios (focused on market risk), as well as a summary of the relevant facts and expected short-term changes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. is generated for our senior management, including the chief executive officer and vice president
executive officers of retail, risks and finance, and an independent member of our board of directors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. is drawn from our risk management framework and policies globally and is validated by local
market risk areas.

***Monthly information:***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. liquidity and market risk: facilitate the analysis of the current activity, including structural
and interest rate risks; it also includes a detailed analysis of alternative measures, stress scenarios and short, long and concentration
liquidity metrics.

Monthly information is generally more detailed than weekly information.

---

The Executive Risk Committee and Risk Control Committee, which are described in detail above, make decisions with regard to risk management in Brazil with representatives of our senior management, including our Chief Executive Officer (CEO), our Vice President Executive Officer of Risk Management (CRO) and other members of the Executive Committee. The main responsibilities of the Executive Risk Committee and Risk Control Committee include defining our level of risk tolerance, monitoring our loan portfolios and market conditions, as well as following up on any recommendations made by the Brazilian Central Bank. They also raise any matters to our board of directors that exceed the authority of the committee. Each of our risk management committees has certain authority and approval levels, in each case subject to Brazilian law and regulations. Decisions at the committee level are intended to be collegial in a manner to ensure that differing opinions are all considered.

**Credit Risk**

Santander Group's risk management model is based on a prudent management, driven by the risk appetite defined by the unit and approved by the headquarters. We operate within the limits of the Santander Group's risk management guidelines and Brazilian Central Bank regulations, in order to protect and optimize capital and promote profitability. One of our credit risk management principles is that of independence among our business areas, providing sufficient autonomy for proper risk management. Another important characteristic of our risk management is the direct involvement of senior management in the decision-making process through credit committees. Our credit risk management process, especially new loan approval and risk monitoring, is structured according to our customer and product classifications, and is divided into retail and wholesale lending.

*[**Table of Contents**](#toc)*<br>

***Retail Lending***

In retail banking, credit requests made by individuals are analyzed by a credit approval system, which assigns a credit rating based on our policies and approved scoring model, which takes into account the credit history of the individual, the individual's relationship with us and the type of credit requested.

These requests can come from one of our many service channels, including branches, internet banking, mobile applications and ATMs.

We use two distinct scoring models depending on the phase in which the customer is in with respect to their interaction with us (the "application" phase and the "behavior" phase). A credit scoring model is applied in the application phase when the customer begins a relationship with us and a behavioral scoring model is used when the customer has already had a relationship with us for a period established by our risk management policies (i.e., during the "ongoing" phase). This policy allows us to evaluate our existing customers with a more complete analysis than if we applied a pure scoring model for all customers.

For financing products offered to SMEs (retail businesses), the method used to evaluate if approval should be granted is based on internally developed credit risk approval limits, as well as the customer´s creditworthiness. These approval methods include system automation, or manual individual analysis, which generates a credit risk rating based on our internal models. Additional information, such as the characteristics of the financing product being offered, including related terms and conditions, as well as collateral granted in connection therewith, is also taken into account in the approval process.

Pre-approved limits on lines of credit for both individuals and SMEs are granted based on creditworthiness, as determined by our scoring criteria. Credit limits are managed based on the performance of the customers, considering each customer's risk profile.

Credit authorization limits are established and these are automatically applied to all credit requests. When an automatic credit decision results in the customer's needs, the commercial area has the authority to submit a request for manual approval. Such approvals are subjected to review by analysts or committees, depending on the value of the loan sought.

There is also a more robust model called Rating Plus which is addressed to mid-size companies a few other retail customers. This model combines the customers' internal and external financial behavior, information obtained from their balance sheets and a questionnaire that is adapted in accordance with the companies' individualities.

The evaluation made by Rating Plus seeks to attribute an internal classification for the costumers defining their risk level in comparison with their creditworthiness. The classification as well as the credit analyses for these customers are usually made manually through specific proposals or limits.

***Wholesale Lending***

In wholesale banking, each customer is analyzed on an individual basis, Commercial and risk areas analyze the client's needs and indicators, analyzing profitability, creditworthiness and adequacy to the risk metrics of Santander Group RAS – Risk Appetite Statement, in order to determine and submit it for approval.

Wholesale lending risk appetite metrics and limits are set annually and tracked monthly through reports sent to the headquarters of the Santander Group. These limits are defined considering the risk appetite of Santander Brasil and the wider Santander Group, in line with current regulations (Brazilian Central Bank and European Central Bank), and the expectations of the commercial area. Individual and sectoral portfolio concentrations are monitored to mitigate the risk of the portfolio.

***Credit Monitoring***

Credit lines to retail customers are reviewed regularly based mainly on their credit risk rating. This process allows improvements in credit exposure to customers who present good credit quality. Additional specific early warnings are automatically generated when deterioration of a customer's credit quality is identified. When this occurs, a process to reduce credit risk and prevent default is implemented. For larger SMEs, this includes monthly monitoring of their financial performance, the financial situation of each enterprise is discussed by specific committees in the presence of the commercial area. These processes are implemented, with the goal of continuously improving the quality of our loan portfolio.

*[**Table of Contents**](#toc)*<br>

Credit lines to wholesale customers and related credit quality are reviewed on an annual basis. When any specific concern the credit quality of a certain customer, we use a customer monitoring system known as SCAN (Santander Customer Assessment Note), which allows possible actions to be taken under the following categories: "monitoring," "intensive monitoring," "proactive monitoring" or "block and exit." A customer subject to action under one of these categories will be reviewed on a quarterly or a semi-annual basis, depending on the situation.

We use proprietary internal rating models to measure the credit quality of a given customer or transaction. Each rating relates to a certain probability of default or non-payment, determined on the basis of the customer's history, with the exception of certain portfolios classified as "low default portfolios." These ratings and models are used in our loan approval and risk monitoring processes.

For a breakdown of our portfolio by internal risk rating, see "Item 4. Information on the Company—B. Business Overview—Selected Statistical Information—Allowance for Loan Losses—Internal Risk Rating."

**Recovery**

Our business recovery area is responsible for all nonperforming portfolios. This area uses statistical tools to study the behavior of customers and then defines, implements and monitors strategies related to these portfolios, seeking to ensure maximum recovery subject to applicable Brazilian law and regulation.

Customers with greater probability of payment are classified as low-risk customers and those with a low probability are classified as high risk. The aforementioned risk classification determines the intensity of collection efforts expended.

The channels of operation are defined as "*Mapa de Responsabilidade*," (Responsibility Map), using the time value of default versus risk value, in addition to other characteristics, to create strategies for recovery.

Our credit recovery tools include daily contact through our call center, digital channels, inclusion of defaulting customers within external sources of credit protection, sending collection letters, and direct contact through our branch network. In addition to the aforementioned tools, we use the following strategies:

&nbsp;&nbsp;&nbsp;&nbsp;• Internal teams specialized in restructuring and debt recovery work directly with defaulting customers
with loans of higher values and/or are overdue more than 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;• We use specialized external firms to collect, report and assess high-risk customers. These firms are
remunerated according to pre-established percentages applied to the amounts recovered.

The digital channels have been increasing in importance and have made it easier for customers to renegotiate debts.

Once we have exhausted all of the credit recovery resources available to us, we conduct sales of any remaining nonperforming loans. These sales are held periodically through an auction process, with the aim of obtaining optimal prices in the markets and thereby reducing the impact on us.

***Assets and Liabilities Committee***

Our asset and liability management strategy is defined by our assets and liabilities committee (ALCO), which operates under the guidelines and procedures established by the Santander Group. Members of the committee include our Chief Executive Officer, Chief Risk Officer, Vice President Executive Officer – Finance and Strategy, Vice President Executive Officer – CFO, Director – Financial Management (ALM) and the Chief Economist. The assets and liabilities committee establishes strategies, policies and procedures with the objective of managing our balance sheet and risk structure.

**Market Risk** 

***Types of market risk***

*Interest rate risk*

Interest rate risk is the possibility that changes in interest rates could adversely affect the value of a financial instrument, a portfolio or our operations as a whole. We are exposed to interest rate risk whenever there is a mismatch between interest rate sensitive assets and liabilities, subject to any hedging we have engaged in using interest rate swaps or other off-balance sheet derivative instruments. Interest rate risk arises in connection with both our trading and non-trading activities.

*[**Table of Contents**](#toc)*<br>

*Credit spread risk*

Credit spread risk arises due to changes in credit spread curves associated with specific issuers and debt types may adversely affect the value of a financial instrument, a portfolio or Santander Group as a whole.

*Exchange rate risk*

Exchange rate risk arises due to the sensitivity of a foreign currency position in relation to a base currency due to a potential change in exchange rates. We are exposed to foreign exchange rate risk as a result of mismatches between assets and liabilities, and off-balance sheet items denominated in different currencies, either as a result of trading or in the normal course of business. We maintain non-trading open currency positions arising from our investments in overseas subsidiaries (such as our Cayman Islands and Luxembourg branches), affiliates and their respective currency funding. Our principal non-trading currency exposure is the U.S. dollar, which, as mandated by our policies, is hedged to the *real* within established limits.

*Equity price risk*

Equity price risk arises due to the sensitivity of an investment position in equity markets to adverse movements in the market prices or in response to expectations of future dividends. Among other instruments, equity price risk affects positions in shares, stock market indices and derivatives using shares as the underlying asset (puts, calls, and equity swaps).

*Commodities price risk*

Commodities price risk relates to the potential negative effect of changes in commodity prices. Our exposure to this risk is mostly concentrated in derivative operations involving commodities for customers.

*Inflation risk*

Inflation risk is the risk that changes in inflation rates may adversely affect the value of a financial instrument, a portfolio or Santander Group as a whole.

*Volatility risk*

Volatility risk is the sensitivity of a portfolio to volatility in a number of risk factors, including interest rates, exchange rates and equity prices. This risk is applicable to financial instruments which have volatility as a variable in their valuation model.

Other, more complex, risks to which we may be exposed include:

*Correlation risk*

Correlation risk is the sensitivity to changes in the relation between risk factors, whether of the same type (for example, between two exchange rates) or of a different nature (for example, between an interest rate and the price of a commodity).

*Market liquidity risk*

Market liquidity risk is the possibility of a Bank entity or the Santander Group as a whole finding itself unable to exit or close a position in time without affecting the market price or the cost of the transaction. This risk can be caused by a decrease in the number of market participants or institutional investors, the execution of large volumes of operations, market instability or increases of the concentration existing in certain products and currencies. Market depth is the main liquidity driver in our trading portfolio, even though our policy is to trade the most liquid assets.

*[**Table of Contents**](#toc)*<br>

Our liquidity risk also arises in non-trading activity, due to the maturity gap between assets and liabilities mostly in the retail banking business.

*Risk of prepayment or cancellation*

In certain transactions, the relevant loan agreement allows, explicitly or implicitly, voluntary prepayment prior to maturity without any penalty, which creates a risk that the cash flows received as a result of the prepayment will be reinvested at a potentially lower interest rate. This mainly affects loans or mortgage.

*Underwriting risk*

Underwriting risk occurs in the underwriting of a placement of securities or another type of debt, assuming the risk of partially owning the issue or the loan due to non-placement of all or any proportion of any issuance among potential buyers.

*Derivatives used in Managing Market Risks*

We use derivatives both in trading and non-trading activities to manage market risks. Trading derivatives are used to eliminate, reduce or modify risk in trading portfolios (interest rate, foreign exchange, commodities and equity price risk), and to provide financial services to customers. Our principal counterparties (in addition to customers) for this activity are financial institutions and the B3. Our main derivative instruments include interest rate swaps, interest rate futures, foreign exchange forwards, foreign exchange futures, foreign exchange options, cross currency swaps, commodities derivatives, equity index futures and equity options and interest rate options.

With respect to non-trading activity, derivatives are used in order to manage interest rate risks and foreign exchange risks arising from asset and liability management activity. We also use interest rate and foreign exchange linear derivatives in non-trading activity.

***Activities subject to market risk***

Our market risk area is responsible for measuring, controlling and monitoring risk, in respect to the above identified areas, as a result of changes in market factors. Market risk arises due to changes and potential volatility in interest rates, exchange rates, share prices and commodities prices, as well as due to liquidity risk of the various products and markets in which we operate.

The following outlines the main source of risk for which we are exposed:

*Trading*

The trading book includes financial services to customers and purchase-sale and positioning mainly in fixed income, equity and currency products. The trading book comprises our proprietary positions in financial instruments held for resale and/or bought to take advantage of current and/or expected differences between purchase and sale prices. This portfolio also includes positions in financial instruments deriving from market-making and sales activities. As a result of trading fixed income, equity, commodities and foreign exchange products, we are exposed to their respective market risks. We are also exposed to volatility when non-linear derivatives are used and credit spreads.

*Non-trading book (banking/structural)*

The non-trading book consists of market risks inherent in the balance sheet, excluding the trading portfolio. These include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. Structural interest rate risks. This arises from mismatches in the maturities and re-pricing
of all assets and liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Structural exchange rate risk/hedging of results and offshore investments. Exchange rate
risk occurs when the currency in which the investment is made is different from the real in companies or branches that are consolidated
and those that are not (structural exchange rate). In addition, exchange rate hedging of future results generated in currencies other
than the real (hedging of results).

*[**Table of Contents**](#toc)*<br>

***Market Risk Management Framework***

Our board of directors is responsible for establishing our policies, procedures and limits with respect to market risk, including which businesses to invest in and maintain. Our Risk and Compliance Committee monitors our overall performance in relation the risks we assume. Together with the local and global assets and liabilities committees, each market risk unit measures and monitors our market and liquidity risk and provides figures to the assets and liabilities committees to use in managing such risks.

Market risk is regulated and controlled through certain policies, set forth in our market and liquidity risk management policies manual, as well as through specific exposure limits established for the entire Santander Group. In addition, authorized products are listed and reviewed periodically.

These policies, procedures and limits on market risk are applicable to all units, businesses or portfolios susceptible to market risk, and are built on five basic pillars, which we believe are vital for correct management of market risks:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. Market and structural risk measurement, analysis and control;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Calculation, analysis, explanation and reconciliation of profit and loss (P&L);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. Definition, capture, validation and distribution of market data;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. Definition of limits, products and underlyings; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v. Consolidation of information.

In turn, our market risk management is guided by the following basic principles:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. Independence of the trading and balance sheet activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Global overview of the risks taken;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. Definition of limits and empowerment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. Control and oversight;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v. Homogeneous aggregated metrics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vi. Homogeneous and documented methodologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vii. Measuring risk;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;viii. Information consolidation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ix. Contingency plans and technical capability.

***Structure of Limits Regarding Market Risk***

The market risk limit structure represents Santander Brasil's risk appetite and is aligned with our global market risk management policies, which encompass all of our business units and serve to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. identify and define the main types of risk incurred in a manner consistent with our business
strategy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. quantify and report to our business segments with respect to appropriate risk levels and
risk profile in line with senior management's assessment of risks to help avoid any of our business segments taking undesired risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. provide flexibility to our business segments to timely and efficiently establish risk positions
that are responsive to market changes and our business strategies, and always within risk levels acceptable to Santander Brasil;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. allow the individuals and teams originating new business to take prudent risks that will
help attain budgeted results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v. establish investment alternatives by limiting equity requirements; and

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vi. define the range of products and underlying assets within which each unit of treasury can
operate, taking into consideration our risk modeling and valuation systems and our liquidity tools. This will help to constrain market
risk within our defined risk strategy.

Global market risk management policies define our risk limit structure while our Risk and Compliance Committee reviews and approves such policies. Business managers administer their activities within these limits. The risk limit structure covers both our trading and non-trading portfolios and includes limits on fixed income instruments, equity securities, foreign exchange and derivative instruments.

Limits considered to be global limits refer to the business unit level. Our business units must comply with approved limits. Potential excesses require a range of actions carried out by the global market risk function unit including (i) providing risk-reducing suggestions and controls, which are the result of breaking "alarm" limits and (ii) taking executive actions that require risk takers to close out positions in order to reduce risk levels.

The market risk limits used by us are established along different metrics intended to cover all activity subject to market risk from many perspectives, applying criteria we believe to be conservative. The principal limits include:

*Trading limits*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. VaR and Stress VaR limits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. limits of equivalent positions and/or nominal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. sensitivity limits to interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. vega and gamma limits; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v. limits aimed at reducing the volume of effective losses or protecting results already generated
during the period:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• loss trigger; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• stop loss.

*Structural limits*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. structural interest rate risk of the balance sheet:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sensitivity limit of net interest margin ("NIM") over a one
year horizon; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sensitivity limit of market value of equity ("MVE");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. structural exchange rate risk comprised of the net position in each currency; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. liquidity risk: limits defined for short, long and concentration metrics and considering
BAU and Stress scenario.

***Market Risk Statistical Tools***

Locally, we use a variety of mathematical and statistical models, including VaR models, historical simulations and stress testing to measure, monitor, report and manage market risk. Such numbers, produced locally, also serve as input for global activities such as evaluations of RORAC, and to allocate economic capital to various activities in order to evaluate the RORAC of such activities.

*Trading Activity*

&nbsp;&nbsp;&nbsp;&nbsp;• VaR: as calculated by us, our internal VaR model is an estimate of the expected maximum loss in
 the market value of a given portfolio over a one-day time horizon at a 99% confidence level, subject to certain assumptions and
 limitations discussed below. Our standard methodology is based on historical simulation of 520 days and is calculated using the VaR
 methodology "full revaluation." In order to capture recent market volatility in the model, the reported VaR is the
 higher between the 1% percentile and the 1% weighted percentile of the simulated PnL distribution. The first VaR figure gives the
 same weight to all observed values, and the second one applies an exponential declining factor to give a higher weight for the most
 recent observations. This methodology makes our VaR numbers react very quickly to changes in current volatility, significantly
 reducing the likelihood of back testing exceptions. We use VaR estimates to alert senior
management whenever the statistically estimated losses in our portfolios exceed prudent levels.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. *Assumptions and limitations:* our VaR methodology should be interpreted in light of the limitations
that (i) a one-day time horizon may not fully capture the market risk of positions that cannot be liquidated or hedged within one day
and (ii) at present, we compute VaR at the close of business and trading positions may change substantially during the course of the trading
day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. *Calibration measures:* in order to calibrate our VaR model, we use back testing, which is a comparative
analysis between VaR estimates and the daily clean Profit and Loss (theoretical result generated assuming the mark-to-market daily variation
of the portfolio considering only the movement of the market variables). The purpose of these tests is to verify and measure the precision
of the models used to calculate VaR.

&nbsp;&nbsp;&nbsp;&nbsp;• Stressed VaR: our stressed VaR model uses the same calculation methodology as VaR with the following
two exceptions: (i) the stressed VaR uses a window of 260 days, instead of 520 days for the VaR; (ii) unlike when calculating the VaR
the higher of the percentile uniformly weighted and the one exponentially weighted is not applied. Instead, only the uniformly weighted
percentile is used. All the other aspects regarding the methodology and the inputs for calculating the stressed VaR are the same as those
for the VaR. To determine the period of observation the market risk area has analyzed the history of the main market risk factors, which
were chosen on the basis of expert criteria, and taking into account the most significant positions of our portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;• Stress Test: this is a simulation technique, which consists of estimating the potential impact on results
by applying different stress scenarios to the trading portfolios and considering the same assumptions according to the relevant risk factor.
These scenarios can replicate events that happened in the past (such as crisis events) or hypothetical scenarios. These results are analyzed
at least monthly and, along with the VaR provide a fuller spectrum of the risk profile.

&nbsp;&nbsp;&nbsp;&nbsp;• Sensitivities: our market risk sensitivity measures gauge the change (or sensitivity) of the market
value of an instrument or portfolio to changes in each of the risk factors. The sensitivity of the value of an instrument to changes in
market factors may be obtained through analytical approximations by partial derivatives or through a full revaluation of the portfolio.

*Non-trading Activities*

&nbsp;&nbsp;&nbsp;&nbsp;• Interest rate gap of assets and liabilities: focuses on lags or mismatches between changes in the value
of assets, liabilities and off-balance sheet items. Gap analysis provides a basic representation of the balance sheet structure and allows
for the detection of interest rate risk by concentration of maturities. It is also a useful tool for estimating the impact of future interest
rate movements on NIM or equity. All on- and off-balance sheet items must be broken down by their flows and analyzed in terms of re-pricing
and maturity.

In the case of those items that do not have a contractual maturity, an internal model of analysis is used and estimates are made of their duration and sensitivity.

&nbsp;&nbsp;&nbsp;&nbsp;• NIM sensitivity: measures the change in the short- and medium-term in the accruals expected over a 12-month
horizon, in response to a shift in the yield curve. The yield curve is calculated by simulating the NIM, with a shift in the yield curve,
as well as for the current scenario. The sensitivity is the difference between the calculation of the two margins.

&nbsp;&nbsp;&nbsp;&nbsp;• MVE sensitivity: Net worth sensitivity measures the interest risk implicit in net worth (equity) over
the entire life of the operation on the basis of the effect that a change in interest rates has on the current values of financial assets
and liabilities. This is an additional measure to the sensitivity of the NIM.

&nbsp;&nbsp;&nbsp;&nbsp;• Value at risk: The VaR for balance sheet activity and investment portfolios.

&nbsp;&nbsp;&nbsp;&nbsp;• Analysis of results arising from the interest rate scenarios established by Circular No. 3,876 of the
Brazilian Central Bank: there are six shock scenarios for MVE sensitivity and two for NIM sensitivity.

&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity risk: our ability to finance our commitments at reasonable market prices, as well as to carry
out our business plans with stable sources of funding. We permanently monitor maximum gap profiles. The measures used to control liquidity
risk are the liquidity gap, stress scenarios and contingency plans.

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity gap: provides information on contractual and expected cash inflows and outflows for a certain
period of time, for each of the currencies in which we operate. The gap measures the net need or excess of funds at a specific date and
reflects the level of liquidity maintained under normal market conditions.

Analysis of scenarios/contingency plan: includes the local and external activities and consists of a formal set of preventive and corrective actions taken in times of liquidity crises. Using analysis of historical scenarios and simulations of impacts on bank liquidity, we define action plans and contingencies to establish roles and responsibilities and levels to trigger the contingency plan. Each unit should prepare its contingency plan. Additionally, Santander Spain must be periodically informed about the contingency plan of each subsidiary. The frequency with which this plan must be updated depends on market liquidity conditions.

***Quantitative analysis***

*Quantitative analysis of daily VaR in 2025*

Our risk performance regarding trading activity in financial markets between 2023 and 2025, measured by daily VaR (measured at a 99% confidence level, over a one day time frame), is shown in the following graph.

![](image_010.jpg)

*[**Table of Contents**](#toc)*<br>

During 2025, VaR fluctuated between R$17.4 million and R$96.6 million, with an average of R$33.0 million. The histogram below shows the distribution of average risk in terms of VaR in 2025, where the accumulation of days with VaR levels between R$30 million and R$50 million can be observed in 87.4% of the distribution.

| Commodity VaR | 0.9 | 0.2 | 1.3 | 9.4 | 0.5 |

---

The average VaR for 2025 was R$33.0 million, with most of the risk due to interest rate positions, and Santander Brasil was relatively conservative in equity and commodities trading activity in line with the approach taken over the last few years.

The average VaR of the four main risk factors, interest rates, equity prices, exchange rates, and commodities, were R$31.1 million, R$9.6 million, R$7.1 million, and R$1.3 million respectively, with a negative average diversification effect of R$33.1 million. The chart below shows the evolution of the VaR for interest rates (IR), exchange rates (FX), equity prices (EQ), and commodities (CM), at a 99% confidence level, over a day time frame and a 15-day moving average.

*Risk Management of Structured Derivatives*

Our structured derivatives activity is mainly focused on designing investment products and managing hedging risks for customers. Our risk management is focused on ensuring that the net risk exposure is the lowest possible. These transactions include options on equities, currencies, fixed-income instruments.

The chart below shows the VaR Vega performance of our structured derivatives business in 2025, 2024 and 2023. In the most recent year, this figure fluctuated around an average of R$5.0 million. In general, the periods with higher VaR Vega levels are related to episodes of significant increases in market volatility.

*Scenario analysis*

Different stress test scenarios were analyzed during 2025. A correlation break scenario generated the results presented below.

*[**Table of Contents**](#toc)*<br>

*Worst Case Scenario*

The table below shows the maximum daily losses for each risk factor (fixed-income, equities and currencies) as of December 31, 2025, in a scenario that uses historical volatilities and simulates variations of the risk factors for +/-3 and +/-6 standard deviations on a daily basis. From this group of scenarios, we generate a table of stress test results, which identifies the largest loss per risk factor. The sum of the largest losses of each risk factor is the result of the Worst-Case Scenario, which considers the break of correlation between risk factors.

| | | | | |
|:---|:---|:---|:---|:---|
| **Worst Case Stress Test** | **Exchange Rate** | **Fixed Income** | **Equity** | **Total** |
|  | **(in millions of R$)** | **(in millions of R$)** | **(in millions of R$)** | **(in millions of R$)** |
| Total trading | (33.1) | (267.0) | (18.9) | (319.0) |

The interest rate risk of our balance sheet management portfolios, measured by the sensitivity of the net margin to a parallel movement of 100 basis points, decreased R$428 million during 2025, reaching a maximum of R$888 million in February 2025. The sensitivity of the market value decreased R$979 million in the year ended December 31, 2025, reaching a maximum of R$2,687 million in January 2025. The main factors that occurred in 2025 and influenced the decrease in sensitivities were the hedging of credit production and the update of the non-performing liabilities model.

**Operational Risk**

We have adopted the definition of the Basel Committee and Brazilian Central Bank for operational risk, which defines operational risk as the possibility of losses resulting from inadequate processes, people and systems, failures, or from external events. This definition includes legal risk associated with the inadequacy or deficiency in executed agreements, as well as penalties for noncompliance with legal provisions and damages for third parties resulting from our activities. This definition does not include strategic risk. Operational risk events might result in financial losses, adverse effects on the continuity of our business, and negative effects on public image and customer experience.

*[**Table of Contents**](#toc)*<br>

To accomplish our operational risk objectives, we have established a risk model based on three lines, aimed at continuously improving and developing our management and control of operational risks. The three lines are:

&nbsp;&nbsp;&nbsp;&nbsp;• *First line*: all business and support areas within Santander Brasil are responsible for identifying,
managing, mitigating and reporting operational risks related to its activities;

&nbsp;&nbsp;&nbsp;&nbsp;• *Second line*: the operational risk and internal control departments is responsible for monitoring
and ensuring control over operational and technological risk management practices throughout the organization. It is also responsible
for implementing and communicating our operational risk culture, defining methodologies, policies, tools, training, applicable procedures
and requirements for the effective management of operational risk;

&nbsp;&nbsp;&nbsp;&nbsp;• *Third line*: the Internal Audit department is responsible for undertaking independent reviews
of the risk management activities carried out by the first and second lines, and for promoting continuous improvements in both lines.

The objectives of the operational risk management model are:

&nbsp;&nbsp;&nbsp;&nbsp;• to disseminate a culture of operational risk management and control, to foster the prevention of risk
events and operational risks losses, and to mitigate their financial, and nonfinancial impacts;

&nbsp;&nbsp;&nbsp;&nbsp;• to provide support to decision-makers within Santander Brasil;

&nbsp;&nbsp;&nbsp;&nbsp;• to ensure there is sufficient coverage to cover the possible impacts of operational risk on an ongoing
basis; and

&nbsp;&nbsp;&nbsp;&nbsp;• to maintain control of operational risk in a manner which is consistent with business strategy.

The following bodies are involved in the implementation of risk management model in order to ensure we have a structured process of operational risk management and decision maker:

&nbsp;&nbsp;&nbsp;&nbsp;• Risk Control Committee (*Comitê de Controle de Riscos*): a committee which aims to perform
a holistic and periodic monitoring of the risks to which Santander Brasil is exposed and to exercise independent control on the risk management
activities;

*[**Table of Contents**](#toc)*<br>

&nbsp;&nbsp;&nbsp;&nbsp;• Senior Forum of Internal Control and Operational Risk (*Fórum Sênior de Controle Interno e Risco Operacional "FSCIRO"*): a senior forum aimed at ensuring and fostering the adequate monitoring, control and mitigation
of operational risks;

&nbsp;&nbsp;&nbsp;&nbsp;• Internal Control and Processes Forum: Executive forum with senior leadership participation, responsible
for oversight, analyzing and making decisions on the internal controls environment, operational risk profile and process management.

&nbsp;&nbsp;&nbsp;&nbsp;• Operational Risk Meeting (*Reunião de Riscos Operacionais*): an independent forum, responsible
for implementing and disseminating cultural norms, methodologies, standards, policies, tools, training and procedures applicable and required
for the effective and efficient management and control of operational risk.

Our risk management model assists managers in achieving their strategic objectives by contributing to the decision-making process and by seeking to reduce operational risk exposure and losses. It is compliant with the applicable regulatory requirements.

**Cybersecurity Risk**

We are exposed to cybersecurity risk as part of our day-to-day operations. We rely on our technological infrastructure, detection tools, protection, event containment measures, technical team training programs, employee training and awareness initiatives, and alignment of our processes with recognized business continuity management practices to manage cybersecurity risk. For more information on our cybersecurity risks and policies, please see "Item 16K. Cybersecurity."

**Social and Environmental Risk**

Since 2002, we have been at the forefront of social, environmental, and climate risk analysis in Brazil, and it has become part of our culture. We consider social, environmental and climate risks when deciding whether to maintain or extend credit. Our Social, Environmental and Climate Responsibility Policy, or "PRSAC," complies with National Monetary Council Resolution No. 4,945/2021 and the SARB 14 self-regulation issued by FEBRABAN. Our PRSAC establishes guidelines for social-environmental practices applicable to business and stakeholder relations, such as relations with suppliers. These practices include social, environmental and climate risk assessment in granting or using credit, which complies with National Monetary Council Resolution No. 4,943/2021. This is carried out through the analysis of the socio-environmental practices of wholesale and core companies (empresas núcleo) SME customers, which have limits or credit risk greater than R$7 million and belong to one of 14 social, environmental and climate priorities sectors, based on their risk level.

We have been signatories of the Equator Principles since 2009. The Equator Principles are a framework used by financial institutions to determine, assess, and manage environmental and social risk in projects, and are based on the Performance Standards on Social and Environmental Sustainability of International Finance Corporation (IFC) and the World Bank Group.

Since 2016, climate change considerations have been progressively incorporated into our credit assessment of wholesale customers. In 2020, a water stress calculator was introduced as part of our socio-environmental assessments, incorporating the concept of customer resilience to both physical and transition risks. This tool evaluates factors such as the customer's economic activity, location within specific hydrographic basins, and the measures adopted to reduce water consumption. Its development was grounded in an assessment of customers' overall vulnerability to climate change, including potential impacts arising from regulatory changes and shifts in consumer preferences. Building on this foundation, we are advancing the assessment of physical climate risks across our customer base by strengthening analytical capabilities and integrating these insights into credit decision-making processes and portfolio management. We believe this ongoing evolution supports more robust risk assessments and enhances our ability to anticipate and manage the impacts of climate-related events on our exposures.

In March 2023, FEBRABAN approved a protocol (Normativo SARB No. 26/2023) that set the standards for managing the risk of illegal deforestation in the bovine meat chain and defined guidelines to be adopted by its signatories, including Santander Brasil. We believe this is a major step forward as it is the first sector-wide environmental protocol for financing beef processing. Since it will apply to every major bank in Brazil, it is considered a highly effective way of sustainable change and addressing deforestation. By signing the protocol, we have aligned our commitment with that of the Brazilian financial industry to require beef processing clients with slaughterhouses in the Brazilian Amazon region to end illegal deforestation by December 2025. This applies to direct suppliers of cattle and Tier 1 indirect suppliers (supplier of the direct supplier). Under this requirement, suppliers must meet mid-term milestones, which consist of having a traceability and monitoring system, and continuously disclosing KPIs to demonstrate they are meeting their commitments. In 2021, well before the publication of the FEBRABAN protocol, we began engaging with more than a dozen beef processing clients about ending deforestation in their supply chain by 2025. This engagement led to several of them declaring commitments online in 2022 and developing plans to check on Tier 1 indirect suppliers and, led Santander Brasil to work with other banks to come up with the FEBRABAN protocol.

*[**Table of Contents**](#toc)*<br>

We believe that assessing the socio-environmental risk in our operations, also enables us to mitigate issues of operational, capital, credit, and reputational risk. Between January 1, 2025 and December 31, 2025, we conducted socio-environmental screening of 918 wholesale corporate customers, 688 Empresas Núcleo (Core Companies) customers, 668 agribusiness operations, 281 collateral assets, 166 real estate projects, and 48 major new projects, including both those subject and not subject to the Equator Principles. Furthermore, wholesale segment customers are screened for environmental, social and climate related concerns by the new customer acceptance department when they begin their commercial relationship with us. See "Item 3. Key Information—D. Risk Factors—Risks Relating to the Brazilian Financial Services Industry and Our Business—Social and environmental risks may have a material adverse effect on us."

**Other Information**

Volatile market conditions arising from the continuation or escalation of the war in Ukraine and uncertainties following the ceasefire agreement in the Middle East, with intensifying trade tensions between the U.S. and the rest of the world, combined with global supply chain disruptions and persistently high inflation, may result in significant changes in macroeconomic conditions, foreign exchange rates, interest rates, and the prices of our securities. Additionally, in Brazil, these global challenges are compounded by domestic factors such as elevated interest rates, stricter regulatory requirements, and individuals and companies over-indebtedness, that could further exacerbate market volatility and adversely affect us.

Industry and Our Business" and "Item 3. Key Information—D. Risk Factors—Risks Relating to Brazil and Macroeconomic

and Political Conditions in Brazil and Globally."

**ITEM 15. CONTROLS AND PROCEDURES**

**15A. Disclosure Controls and Procedures**

As of December 31, 2025, with the supervision and participation of our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), we performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). As described below, there are inherent limitations to the effectiveness of any control system, including disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can provide only reasonable assurance of achieving their control objectives.

Based on such evaluation, our CEO and CFO concluded that our disclosure controls and procedures are effective in ensuring that information we are required to disclose in the reports we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and (ii) accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosures.

In addition, as required by the Brazilian Central Bank through CMN Resolution No. 4,968/21 and Resolution No. 130/21, the report related to the quality and adequacy of the internal controls will be issued within 45 days after the expected date of publication of the Brazilian GAAP financial statements, which is scheduled to be February 27, 2026.

**15B. Management's Annual Report on Internal Control over Financial Reporting**

Our management is responsible for establishing and maintaining an adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act.

Our internal control over financial reporting process is designed by, or under the supervision of, our principal executive and financial officers and incorporates supervision from effected by our Board of Directors, management and other personnel. The purpose is to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes, in accordance with generally accepted accounting principles. For us, generally accepted accounting principles refer to IFRS as issued by the IASB.

Our internal control over financial reporting includes those policies and procedures that:

&nbsp;&nbsp;&nbsp;&nbsp;• pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions
and dispositions of our assets;

&nbsp;&nbsp;&nbsp;&nbsp;• provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated
financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made
only in accordance with authorizations of our management and officers; and

&nbsp;&nbsp;&nbsp;&nbsp;• provide reasonable assurance of prevention or timely detection of unauthorized acquisition, use or disposition
of our assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projected effectiveness of controls in future periods is subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures deteriorates.

We have adapted our internal control over financial reporting to the international standards and comply with the guidelines set by the Committee of Sponsoring Organizations of the Treadway Commission, or "COSO," in its Internal Control – Integrated Framework 2013. These guidelines have been extended and implemented for the Santander Brasil group, applying a common methodology and standardizing the procedures for identifying processes, risks and controls.

***Risk Management Integrated Framework***

The documentation process in our companies has been constantly directed and monitored by a global coordination team, which sets development guidelines and supervises execution at the unit level.

The general framework is consistent, as it assigns specific responsibilities to management regarding the structure and effectiveness of the processes related directly and indirectly with the production of consolidated financial statements, as well as the controls needed to mitigate the risks inherent in these processes.

*[**Table of Contents**](#toc)*<br>

With the supervision and participation of management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2024, based on the framework set by the Committee of Sponsoring Organizations of the Treadway Commission Integrated Framework 2013.

Based on this assessment, which was carried out through February 27, 2026, our management concluded that as of December 31, 2025, its internal control over financial reporting was effective based on those criteria.

PricewaterhouseCoopers Auditores Independentes Ltda. which has audited our consolidated financial statements for the year ended December 31, 2024, has also audited the effectiveness our internal controls over financial reporting under auditing standards of the Public Company Accounting Oversight Board (United States) as stated in their report appearing in our consolidated financial statements included in "Item 18. Financial Statements."

**15C. Attestation Report of the Registered Public Accounting Firm**

For the report, dated February 27, 2026, from PricewaterhouseCoopers Auditores Independentes Ltda., our registered public accounting firm, on the effectiveness of our internal control over financial reporting as of December 31, 2025, see "Item 18. Financial Statements."

**15D. Changes in Internal Control over Financial Reporting**

There was no change in our internal control over financial reporting that occurred during the period covered by this annual report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

**ITEM 16. [RESERVED]**

**16A. Audit Committee Financial Expert**

The Board of Directors has determined that one of the members of our audit committee, Mr. Luiz Carlos Nannini a is an "Audit Committee Financial Expert" and meets the requirements set forth by the SEC and NYSE. He is, as are all other current members of the audit committee, deemed independent under the applicable Brazilian law and the regulations of the SEC and NYSE.

For more details about the audit committee, refer to "Item 6. Directors, Senior Management and Employees—C. Board Practices—Board Advisory Committees—Audit Committee."

**16B. Code of Ethics**

The Code of Ethical Conduct, the central element the Governance Compliance, is applicable to the members of the Boards of Directors, Executive Officers and to all employees and trainees ("Persons Subject to the Code of Ethical Conduct") of Santander Brasil and its subsidiaries. It defines the principles that should guide both the personal and professional behavior of the Persons Subject to the Code of Ethical Conduct. They must know the Code of Ethical Conduct and seek to promote it, by championing and striving for its enforcement, and also have the obligation to attend and participate in all assigned training activities in order to become appropriately acquainted with the Code of Ethical Conduct. The Persons Subject to the Code of Ethical Conduct should be guided by ethical principles and rules of conduct that are consistent with our values.

The Code of Ethical Conduct helps us to establish respectful and transparent relationships and aims for the accomplishment of Santander Brasil's obligations to its customers, employees, shareholders, partners, regulators and society as a whole. The Code of Ethical Conduct should also be a reference for compliance with legal duties and for the maintenance of commercial relationships founded on trust with partners and customers.

A copy of our Code of Ethical Conduct is filed as Exhibit 11.1 to this annual report.

**16C. Principal Accountant Fees and Services**

The balance of "Other general administrative expenses—Technical reports" includes the fees billed by the consolidated companies (detailed in the accompanying Appendix I of the consolidated financial statements included elsewhere in this annual report) to PricewaterhouseCoopers Auditores Independentes Ltda. for the fiscal years ended December 31, 2025 and 2024, as follows:

---

| | | |
|:---|:---|:---|
|  | **For the year ended December 31,** | **For the year ended December 31,** |
|  | **2025** | **2024** |
|  | **(in millions of R$)** | **(in millions of R$)** |
| Audit of the annual financial statements of the companies audited (constant scope of consolidation) | 31.5 | 30 |
| Audit related | 0.3 | 0.6 |
| Tax services | 0.2 | 0.1 |
| Others | 2.4 | 2 |
| **Total** | **34.4** | **32.7** |

---

The approximate value of withholding taxes in respect of the audit fees for the year ended December 31, 2025, according to applicable law totaled R$5.7 million.

The services commissioned from our auditors meet the independence requirements stipulated by the Brazilian Central Bank and CVM regulation and by the Sarbanes-Oxley Act of 2002, and they did not involve the performance of any work that is incompatible with the audit function.

If we are required to engage an auditing firm for audit and audit-related services, those services and any fees paid to the auditing firms must be pre-approved by the audit committee.

Our Audit Committee pre-approves all audit and non-audit services to be performed by our registered public accounting firm.

**16D. Exemptions from the Listing Standards for Audit Committees**

Under NYSE and SEC rules for listed companies, we must comply with Rule 10A-3 under the Securities Exchange Act (Listing Standards Relating to Audit Committees). Rule 10A-3 provides that we should establish an audit committee composed of members of the Board of Directors, meet the requirements specified in the listing standards, or appoint and establish a board of auditors or similar body to perform the role of the audit committee, in reliance on the general exemption of audit committees of foreign private issuers set forth in Rule 10A-3(c) (3) of the Securities Exchange Act.

In accordance with the rules of the Brazilian Central Bank, we constituted a body similar to the audit committee of the Board of Directors of an American company, which we refer to as our "Audit Committee."

Pursuant to Exchange Act Rule 10A-3(c)(3), which provides for an exemption under the rules of the SEC regarding the audit committees of listed companies, a foreign private issuer, such as us, is not required to have an audit committee equivalent to or comparable with a U.S. audit committee, if the foreign private issuer has a body established and selected pursuant to home country legal or listing provisions expressly requiring or permitting such a body, and if the body meets certain requirements. As a foreign private issuer, we rely on the exemption under Rule 10A-3(c)(3) of the Exchange Act with respect to our Audit Committee, and we believe that our audit committee complies with the aforementioned exemption requirements. Except in these respects, our audit committee performs the functions of the audit committees of U.S. companies.

**16G. Corporate Governance**

In December 2012, primarily in response to the requirements of the European Banking Authority, Santander Spain adopted a corporate governance framework (Marco de Gobierno Interno del Grupo Santander). The purpose of the framework is to organize and standardize the corporate governance practices of Santander Spain and its most significant subsidiaries, including us, in order to enhance the ability of Santander Spain to manage the risks arising from Santander group operations around the world.

*[**Table of Contents**](#toc)*<br>

The three pillars of the framework are (i) an organizational model based on functions subject to internal governance, (ii) terms of reference according to which Santander Spain exercises control and oversight over its subsidiaries and participates in specific decisions as their controlling shareholder, and (iii) corporate models establishing common guidelines for the management and control of Santander Spain's subsidiaries, subject to local autonomy considerations. In general, the framework purports to implement organizational and procedural changes rather than mandating particular substantive outcomes. However, in some cases, and subject to the limitations there set forth, the framework states that Santander Spain may require that its subsidiaries make substantive changes or take specific actions. The framework enables Santander Spain to participate in the decision-making processes of its subsidiaries by requiring its approval of certain decisions that may have a significant impact on the Santander Group as a whole due to their significance or potential risk, such as decisions relating to mergers and acquisitions, capital structure, dividends and risk tolerance, among other things. The framework also requires that a single person at each subsidiary be in charge of each function subject to internal governance and gives Santander Spain the authority to participate in the appointment, evaluation and compensation of each such person.

By its own terms, the framework as a whole is premised on the legal and financial autonomy of the subsidiaries and does not empower Santander Spain to supplant its subsidiaries' decision-making processes. Moreover, each of the three pillars of the framework is explicitly made subject to local legal requirements. We approved the adoption of this corporate governance framework in May 2013, and have approved all subsequent amendments since then (the latest one was approved in December 2019), subject to the precedence of applicable Brazilian laws and regulations and the limitations imposed thereby such as banking secrecy laws, and subject also to our corporate governance practices, including our policies for related party transactions and for disclosure of material acts and facts.

As a result of the precedence given to local legal requirements in the framework itself and in our adopting resolutions, we do not expect that the adoption of the corporate governance framework will affect our ability to comply with applicable corporate governance regulations, including the rules of the Brazilian Central Bank, CVM and B3, and SEC and NYSE rules applicable to foreign private issuers.

Pursuant to Section 303A.11 of the Listed Company Manual of the NYSE, we are required to provide a summary of the significant ways in which our corporate governance practices differ from those required for United States resident companies under the NYSE listing standards. Section 303A of the NYSE Listed Company Manual sets forth certain corporate governance requirements that a company must satisfy to be listed on the NYSE. However, exemptions from many of the requirements are available to foreign private issuers such as us. As a foreign private issuer, we are permitted to and we will, follow home country practice in lieu of the NYSE corporate governance standards, from which we are exempt.

A discussion of the significant differences between Brazilian corporate governance standards that govern our practices and the NYSE standards applicable to U.S. companies follows below. It includes only a brief summary description of our corporate governance practices.

**Principal Differences between Brazilian and U.S. Corporate Governance Practices**

We are also subject to the NYSE corporate governance listing standards. As a foreign private issuer, the standards applicable to us are considerably different than the standards applied to U.S. listed companies. Under the NYSE rules, we are required only to: (i) have an Audit Committee or audit board, pursuant to an applicable exemption available to foreign private issuers, that meets certain requirements, as discussed below, (ii) provide prompt certification by our Chief Executive Officer of any material noncompliance with any applicable NYSE corporate governance rules, (iii) submit an executed written affirmation annually to the NYSE and submit an interim written affirmation each time a change occurs to the board or any of the committees subject to Section 303A of the NYSE rules, and (iv) provide a brief description of the significant differences between our corporate governance practices and the NYSE, corporate governance practices required to be followed by U.S. listed companies. The discussion of the significant differences between our corporate governance practices and those required of U.S. listed companies follows below, as required for foreign private issuers by NYSE Rule 303A.11.

*[**Table of Contents**](#toc)*<br>

***Majority of Independent Directors***

The NYSE rules require that a majority of the board must consist of independent directors. As a company with a majority of our voting shares being beneficially owned by another entity (Santander Spain), we are not required to comply with this rule. Independence is defined by various criteria, including the absence of a material relationship between the director and the listed company. Currently, our Board of Directors must have at least five members, at least 20.0% of which must be independent, as determined pursuant to Article 14 of our By-Laws. Currently, six members of our Board of Directors are deemed independent (representing 55% of the composition of our Board of Directors). Also, Brazilian Corporate Law, the Brazilian Central Bank and the CVM have established rules that require directors to meet certain qualification requirements and that address the compensation, duties and responsibilities of, as well as the restrictions applicable to, a company's executive officers and directors. While we believe that these rules provide adequate assurances that our directors are independent and meet the requisite qualification requirements under Brazilian law, we believe that such rules would permit us to have directors that would not otherwise pass the test for director independence established by the NYSE, Brazilian Corporate Law requires that our directors shall be elected by our shareholders at an annual shareholders' meeting. Currently, all of our directors are elected by our shareholders after recommendation of the Nomination and Governance Committee, for a term of two years.

***Executive Sessions***

NYSE rules require that independent directors must meet at regularly scheduled executive sessions without management present. Brazilian Corporate Law does not have a similar provision. According to Brazilian Corporate Law, up to one-third of the members of the Board of Directors can be elected from management members. Our Chief Executive Officer, Mario Roberto Opice Leão, is a member of our Board of Directors. There is no requirement that our independent directors meet regularly without management. As a result, our independent directors on our board do not typically meet in executive session.

***Committees***

NYSE rules require that listed companies have a nominating/corporate governance committee and a compensation committee composed entirely of independent directors and governed by a written charter addressing the committee's required purpose and detailing its required responsibilities. Because we are a controlled company, we are not required to comply with this rule. The responsibilities of the nominating/corporate governance committee include, among other things, identifying and selecting qualified board member nominees and developing a set of corporate governance principles applicable to the company. The responsibilities of the compensation committee, in turn, include, among other things, reviewing corporate goals relevant to the chief executive officer's compensation, evaluating the chief executive officer's performance, approving the chief executive officer's compensation levels and recommending to the board non-chief executive officer compensation, incentive compensation and equity-based plans.

In February 2017, our Board of Directors approved the terms for the establishment of our Nomination and Governance Committee. The Nomination and Governance Committee also oversees corporate governance at Santander Brasil. In addition, CMN rules require us to have a Compensation Committee composed of at least three members. We have created the Compensation Committee whose function is to advise our Board of Directors on matters in connection with, but not limited to (i) fixed and variable compensation policies and benefits and (ii) the long-term incentive plan. See "Item 6. Directors, Senior Management and Employees—C. Board Practices" for a complete description of all of our board advisory committees. Pursuant to Brazilian Corporate Law, the aggregate compensation for our directors and executive officers is established by our shareholders.

***Audit Committee and Audit Committee Additional Requirements***

NYSE rules require that listed companies have an audit committee composed that (i) is composed of a minimum of three independent directors who are all financially literate, (ii) meets the SEC rules regarding audit committees for listed companies, (iii) has at least one member who has accounting or financial management expertise and (iv) is governed by a written charter addressing the committee's required purpose and detailing its required responsibilities.

CMN rules require us to have an audit committee of at least three independent members, of which one must be an independent director. The audit committee is elected by the Board of Directors, SEC Rule 10A-3 provides that the listing of securities of foreign private issuers will be exempt from the audit committee requirements if the issuer meets certain requirements. Our Audit Committee allows us to meet the requirements set forth by this rule. See "Item 16D. Exemptions from the Listing Standards for Audit Committees."

***Shareholder Approval of Equity Compensation Plans***

NYSE rules require that shareholders be given the opportunity to vote on all equity compensation plans and material revisions thereto, with limited exceptions. Under Brazilian Corporate Law, shareholders must approve all stock option plans. In addition, any issuance of new shares that exceeds our authorized share capital is subject to shareholder approval. Our shareholders do not have the opportunity to vote on all equity compensation plans.

*[**Table of Contents**](#toc)*<br>

***Corporate Governance Guidelines***

NYSE rules require that listed companies adopt and disclose corporate governance guidelines. We comply with the corporate governance guidelines under applicable Brazilian law. The corporate governance guidelines applicable to us under Brazilian law are consistent with the guidelines established by the NYSE.

Pursuant to the practices of corporate governance guidelines, on September 22, 2010, our Board of Directors approved a policy that regulates related party transactions, which was last revised on January 27, 2023. This policy provides rules which aim to ensure that all decisions, in particular those involving related parties and other situations with potential conflict of interests will be aligned with our interests and those of our shareholders. The policy applies to all employees, Directors and Executive Officers of Santander Brasil.

***Issuances of Shares***

NYSE rules require shareholder approval prior to the issuance of shares, or securities convertible into or exercisable for shares, if (1) the shares have, or will have upon issuance, equal or an excess of 20% of the voting power outstanding before the issuance of such shares; or (2) the number of shares to be issued is, or will be upon issuance be equal to or in excess of 20% of the number of shares outstanding before the transaction.

Pursuant to the Brazilian Corporate Law, the by-laws of companies may permit increases in capital stock without amendments to the by-laws. Such a permission may specify (i) the limit of the capital increase in terms of total amount or number of shares, the type and classes of the shares that may be issued; (ii) whether the issuance of new shares is to be approved by the general shareholders' meeting or the board of directors; (iii) any conditions to which the issuance of new shares may be subject; and (iv) the circumstances under which shareholders are to benefit from preemptive rights to subscribe for shares. Pursuant to our By-Laws, our board of directors is authorized to approve capital increases involving the issuance of up to 9,090,909,090 shares. Any capital increase is subject to the applicable disclosure requirements set forth in the regulations issued by the CVM regulation, including but not limited to the disclosure of a material fact disclosing the capital increase and the publication of the minutes of the relevant corporate body's meeting which approved the matter.

***Code of Ethical Conduct***

NYSE rules require that listed companies adopt and disclose a code of conduct and ethics for Directors, Officers and employees, and promptly disclose any waivers of the code for Directors or Executive Officers. Applicable Brazilian law does not have a similar requirement. We adopted a Code of Ethical Conduct on February 27, 2009, last revised on June 21, 2023, which regulates the set of ethical principles that shall guide the conduct of our employees, officers and directors of Santander Brasil, as well as of its affiliates. Our Code of Ethical Conduct complies with the requirements of the Sarbanes-Oxley Act and the NYSE rules.

***Internal Audit Function***

NYSE rules require that listed companies maintain an internal audit function to provide management and the audit committee with ongoing assessments of the company's risk management processes and system of internal controls.

CMN rules also require us to have an internal audit function, and our internal audit department works independently to conduct structured examinations, analyses, surveys and fact-finding to evaluate the integrity, adequacy, effectiveness, efficiency and economy of the information systems processes and internal controls related to our risk management. The internal audit department reports on an ongoing basis to the audit committee. In carrying out its duties, the internal audit department has access to all documents, records, systems, locations and professionals involved with the activities under review.

***Other Corporate Frameworks***

On the recommendation of our controlling shareholder, our Board of Directors analyzed and approved the adoption of a series of corporate frameworks to matters such as: (i) internal audit; (ii) accounting and disclosure of financial information; (iii) risk control; (iv) communication and branding; (v) human resources; (vi) information technology; and (vii) money-laundering protection. Currently, we have a total of 16 frameworks (*Marcos Corporativos*) in force. We believe that these frameworks will continue to enhance the formalization of our governance and internal controls structures.

**16K. Cybersecurity**

***Introduction and Overview***

We have security measures in place to mitigate the risk of cybersecurity threats affecting our technology environment and our business. Our cybersecurity policies and programs are based on Santander Spain's frameworks and policies, which are aligned with the NIST CSF – Cybersecurity Framework, and we have also taken into consideration the practices set forth in the ISO-27002 to assist us in formulating such security measures. These measures include governance, anticipate, protect, detect and respond processes and controls including, but not limited to, a risk management program, a training and awareness program, access and privilege management, segregation of test and production environments, network security analysis, baseline configuration of hardware and software, activity log correlation, malware prevention and remediation, business continuity management, security analysis of third-party operations, and cyber incident management. Our cybersecurity team and committees employ a range of security processes and solutions, and work to disseminate these measures within our organization, including through regular compliance checks and continuous monitoring of network activity by the Santander Group's Global Security Operations Center ("SOC") and security tests performed by independent companies.

***Risk Management Model***

Our operational risk management and control model is based on a continuous process of identifying, evaluating and mitigating sources of risk, regardless of whether they have materialized or not. Throughout the application of this process, risk management priorities are established, and internal controls are defined and executed to manage and mitigate the risk across the organization.

Our operational risk model establishes the items needed to manage and control operational risk properly according to regulatory standards and best management practices. Its phases are: (i) strategic planning; (ii) identification and assessment of risks and internal controls; (iii) ongoing monitoring of the operational risk profile; (iv) implementation of actions to manage the risks, including mitigation measures; and (v) disclosure, reporting and escalation of relevant matters. "Heracles," which is our internal management and reporting system for operational risk, supports the operational risk program and tools with a Governance, Risk and Compliance ("GRC") approach. It provides information for management and reporting throughout Santander Brasil. Heracles also facilitates better operational risk management decisions by using a common set of taxonomies and methodological standards to allow information consolidation, duplication prevention and reporting simplification.

*[**Table of Contents**](#toc)*<br>

***Risk Management Process and Tools***

Risk Control Self-Assessment ("RCSA") is a qualitative process that allows us to identify, assess and measure, in a dynamic and proactive way, the material operational risks that could prevent the business or support units from achieving their objectives, as well as the effectiveness of the controls linked to their mitigation. Our RCSA integrates specific reviews that allow us to identify cyber, technology, fraud, third-party supplier and other risk as well as other risk drivers that could lead to operational risk as well as the failure to meet regulatory expectations. In addition, the RCSA incorporates reviews related to regulatory compliance, conduct and financial crime risk.

Other instruments are used to analyze and manage operational risk, such as: (i) metrics, (ii) risk scenarios, (iii) the assessment of new products and services, and transformation initiatives; (iv) business continuity plans (BCP); (v) review of cyber corporate insurance; (vi) review of the management perimeter; (vii) recommendations from internal and external auditors, consultants and supervisors; and (viii) the quality assurance process.

***Business Continuity and Crisis Management***

Our business continuity management model takes into consideration both local (e.g., Brazilian Central Bank) and international guidelines (e.g., European Central Bank guidelines, CIMA – Cayman Islands Monetary Authority guidelines) for cybersecurity risks and includes plans to deal with severe events. We review the impact these events may have on day-to-day operations and endeavor to mitigate such threats. Our crisis governance mechanisms include our senior management as well as committees formed by previously defined and approved members. We also have mechanisms to trigger business continuity plans in case of cyber, operational and financial crises which involve the departments necessary to act and support our operations in the preparation and implementation of strategies to contain these types of crises.

**Training & Awareness (Secure UX)**

We also perform cyber awareness campaigns for our employees and customers, including annual and mandatory training for all employees, an annual event for our executive personnel (called Cyber Defenders), security campaigns for our customers and society at large with influencers on social media and increasing information on how to use our products in a safer way. Furthermore, we cooperate and exchange information and experience relating to cybersecurity with local and international security communities, such as local telecommunications companies and other financial institutions and as a member of the Financial Services – Information Sharing and Analysis Center community.

***Cybersecurity Team, CISO and Oversight***

Our cybersecurity team is composed of dedicated personnel who have experience in cybersecurity in a financial institution context. This team has overall oversight responsibility for our cybersecurity processes and cyber risk management and also relies on the internal controls team, audit team and our risk and compliance committee to ensure oversight and controls effectiveness.

Our local chief information security officer, or "CISO," has been active in the technology areas of the Santander Group for more than 24 years, including strategic leadership roles for technological integration projects. He has a degree in information systems, and received a master's degree in strategic information technology management. At Santander Brasil, our local CISO reports directly to our Technology and Operations Vice President.

***Cybersecurity Committees***

Cybersecurity topics are deliberated in executive committees that have the role of informing and providing supporting materials to our executives and advisors to ensure the best decision-making for the business. Our CISO also regularly updates our audit committee and our risk and compliance committee on Santander Brasil cybersecurity programs, material cybersecurity risks and mitigation strategies, providing periodical reports (annually or ad hoc) that cover, among other topics, our risk exposure, third-party assessment results, maturity of our subsidiaries and incidents that may have happened during the period. Such executive committees support our board of directors.

Our board of directors has overall oversight responsibility for our risk management, and delegates cybersecurity risk management oversight to our risk and compliance committee and to our audit committee. Our audit committee is responsible for providing our board of directors and senior management with an independent assessment of the quality and effectiveness of internal control, cyber risk management and governance of cybersecurity controls. Additionally, our risk and compliance committee is responsible for advising our executive committee as an instrument for effective risk control, ensuring that they are managed according to the level of risk appetite approved by our board of directors.

*[**Table of Contents**](#toc)*<br>

Senior management's participation in incident management is documented using a model with three levels of committees—bronze, silver and gold. Each level is based on an incident's severity, such that members of our management have different roles and responsibilities after our crisis management director disclosures that we are undergoing a special cybersecurity event.

In 2025, we continued to strengthen our cybersecurity and fraud ecosystems, proposing strategies to respond to a constantly changing threat environment, while supporting commercial value and improving the safety environment for clients. In 2026, we will prioritize monitoring the implementation of the technology and operations transformation model, as well as our positioning in cybersecurity, especially to continue maturing, improving, and evolving the cybersecurity defenses, with a special focus on emerging threats.

***Cybersecurity Certifications***

The Santander Group, which includes Santander Brasil and its subsidiaries, has ISO 27001 certification for the key global cybersecurity processes that support our global services. This external recognition, verified through an onsite inspection, confirms our alignment with industry best practices in terms of information security for the following key processes: (i) security operations center, or SOC alert management, (ii) cyber incident management, (iii) malware protection for endpoint security and (iv) attack surface management. We also hold a Service Organization Controls – SOC 1 Type 2 Report (SSAE 18), which provides an independent external recognition for the design and operating effectiveness of global cybersecurity controls, and focus on global cyber products and controls.

***Third-Party Risk Management***

Santander Brasil's external suppliers, who are engaged by Santander Brasil's various business areas, are subject to our third-party risk management process, aiming to certify and assess the vendor processes, giving us a broader visibility on their safety and improvements needed. To do so, we work together with several departments building a transversal view of risks across the cybersecurity, privacy and data protection and business continuity management functions. The objective is to provide a 360º view of third-party gaps and to support decision-makers in supplier engagement and risk management, improving the quality of the service these suppliers provide to the customers.

***Cybersecurity Threats and Incidents***

In 2025, we have continued evolving our cyber defenses in line with our cybersecurity strategy and key strategic initiatives. New controls were developed and implemented following a cyber-threat-led approach, covering current areas of risk and new attack methods, notably around supply chain, backup and recovery and fraud prevention measures reinforced by leveraging behavioral biometric solutions and machine learning technology.

To strengthen our response, streamline operations and maximize resources, we continue to operate the Santander Fusion Center, which enables closer collaboration between our various teams involved in cybersecurity. The Fusion Center operates 24 hours a day, 7 days a week, providing services to Santander Brasil and all its subsidiaries, detecting, monitoring, and responding to operational failures and cybersecurity events.

In parallel, we are preparing for the new requirements of upcoming regulations on cybersecurity matters, while assessing the pros and cons derived from emerging technologies, such as AI. Santander Brasil is implementing a Responsible AI framework that involves different areas (Legal, Risks, Chief Privacy Officer, Cyber Security, Architecture, Engineering) to evaluate each use case implementation and mitigate risks.

During the year ended December 31, 2025, we did not identify any cybersecurity threats that have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition.

However, despite our efforts, we cannot eliminate all risks from cybersecurity threats, or provide assurances that we have not experienced any undetected cybersecurity incident or that we will not experience cybersecurity incidents in the future.

See also "Item 3. Key Information—D. Risk Factors—Risks Relating to the Brazilian Financial Services Industry and Our Business—Failure to adequately protect ourselves against risks relating to cybersecurity could materially and adversely affect us. We are also subject to increasing scrutiny and regulation governing cybersecurity risks."

**Report of independent registered public accounting firm**

To the Board of Directors and Stockholders

Banco Santander (Brasil) S.A.

**Opinions on the financial statements and internal control over financial reporting**

We have audited the accompanying consolidated balance sheets of Banco Santander (Brasil) S.A. and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of income, comprehensive income, changes in stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

**Basis for opinions**

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Item 15B - "Management's Annual Report on Internal Control over Financial Reporting". Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

![](bsbrform20f2025_002.jpg)

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

**Supplemental information**

The reconciliation of stockholders' equity and net income as of and for the years ended December 31, 2025, 2024 and 2023 and the statements of value added for the years ended December 31, 2025, 2024 and 2023 included in Appendix I and II, respectively, have been subjected to audit procedures performed in conjunction with the audit of the Company's consolidated financial statements. The supplemental information is the responsibility of the Company's management. Our audit procedures included determining whether the supplemental information reconciles to the consolidated financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the reconciliation of stockholders' equity and net income, we evaluated whether the Appendix I, including its form and content, is presented in conformity with the financial statements and accounting records, as applicable, as well as performed procedures to test the completeness and accuracy of the information presented in the supplemental information. Additionally, in forming our opinion on the statements of value added, we evaluated whether this Appendix II, including its form and content, is presented in conformity with the financial statements and accounting records, as applicable, and presented in conformity with Brazilian Corporate Law. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the consolidated financial statements as a whole.

**Definition and limitations of internal control over financial reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**Critical audit matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

**Measurement of expected credit losses**

As described in Notes 1(c.3.1(ii)), 2(h), 9 and 46(b) to the consolidated financial statements, management measures the expected credit losses at the probability-weighted estimate of credit losses, that involves management's judgment, as set forth in IFRS 9 - "Financial Instruments". At December 31, 2025, the impairment losses on loans and receivables to customers at amortized cost was BRL 37,491,433 thousand and total loans and receivables to customers at amortized cost was BRL 595,626,402 thousand. Management calculates Expected Credit Losses ('ECL') using three main components: a Probability of Default ('PD'), Loss Given Default ('LGD') and Exposure At Default ('EAD') including individual and collective models. The ECL measurement is based on management's estimate of the present value of future cash flows expected to be received and involves the use of a variety of assumptions and internal and external factors, including credit quality, economic and financial situation, guarantees, segment and economic scenarios. Additionally, management has considered forward-looking information, including changes in macroeconomic scenarios impacting the calculation model for provisioning expected credit losses.

The principal considerations for our determination that performing procedures relating to the measurement of expected credit losses is a critical audit matter are (i) there was significant judgment applied by management in determining the expected credit losses, in particular the assumptions used in determining the PD,LGD and EAD parameters, which in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence obtained relating to these assumptions; and (ii) the audit effort involved use of professionals with specialized skills and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included understanding and testing the effectiveness of controls relating to management's measurement of expected credit losses, which included controls over the assumptions used. These procedures also included, among others: (i) the involvement of professionals with specialized skills and knowledge to assist in testing management's process for determining the expected credit losses, including evaluating the appropriateness of the methodologies and models applied, testing the accuracy and completeness of data used,

and evaluating the reasonableness of significant assumptions; (ii) the analysis of management's accounting policies in comparison with IFRS 9; and (iii) analysis over management's disclosures in the consolidated financial statements.

**Provisions and contingencies for judicial and administrative proceedings** 

As described in Notes 1(c.3.1(iii)), 2(q) and 22 to the consolidated financial statements, provisions and contingencies for judicial and administrative proceedings are recorded when their risk of loss are considered probable and the amounts can be reliably measured, based on the nature, complexity and history of lawsuits and the opinion of legal counsel. As of December 31, 2025, the Company has recorded provisions for judicial and administrative proceedings of BRL 9,495,060 thousand. The Company also discloses contingencies in circumstances where management concludes no loss is probable or reasonably estimable, but it is reasonably possible that a loss may be incurred.

The principal considerations for our determination that performing procedures relating to provisions and contingencies for judicial and administrative proceedings is a critical audit matter are (i) the significant judgment applied by management when assessing the likelihood of a loss being incurred and the potential amount of the judicial and administrative proceedings; and (ii) a high degree of auditor judgment and effort in evaluating management's assessment of the provisions for judicial and administrative proceedings, including the involvement of professionals with specialized skills and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to identifying, assessing, monitoring, measuring, recording, and disclosing the provisions for judicial and administrative proceedings, including the completeness and accuracy of the data used. These procedures also included, among others (i) confirming the existence of active processes and the completeness of the information with the law firms responsible for administrative and legal proceedings, (ii) evaluating the reasonableness of management's assessment prognosis for a sample of proceedings taking into consideration the individual progress of similar proceedings, with the assistance of our professionals with specialized skills and knowledge, and (iii) evaluating the sufficiency of the Company's provisions and contingencies for judicial and administrative proceedings disclosures.

While uncommon, non-convertibility may arise when a government enforces currency controls that forbid currency exchange or restrict the amount of foreign currency transactions. The amendment to IAS 21 provides guidance on how entities should assess whether a currency is readily convertible and how to determine a spot exchange rate for currencies with limited exchangeability, as well as requires the disclosure of information that enables Financial Statement users to understand the impacts of a non-convertible currency. These changes are effective as of January 1, 2025, did not generate a material impact on Santander's consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Adoption of IFRS 9 for Hedge Accounting –** During fiscal year 2025, Santander began applying requirements established by IFRS 9 for hedge relationships. The main impacts of this change on the accounting of hedge relationships stem fundamentally from: the separation of the time value of options, when the hedged risk is intrinsically mandatory; the separation of the forward element of currency forward contracts, for all types of hedges; and the separation of the foreign currency basis differential of a currency derivative, for each hedge relationship. The application of these options to hedges designated prior to December 31, 2025, did not generate a material impact on Santander's consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Global Minimum Tax – Pillar 2 -** The Pillar 2 rules of the Global Minimum Tax Model Rules, approved in 2021 by the Organization for Economic Co-operation and Development (OECD), stipulate that multinational groups with revenues exceeding €750 million are subject to a minimum tax rate of 15% on adjusted accounting profit, calculated on a jurisdictional basis. The OECD supplemented these rules by approving administrative guidelines and transitional safe harbors applicable to the fiscal years 2024 to 2026. In January 2026, the application of the transitional safe harbors was extended for another year, and new permanent safe harbors were approved with the aim of simplifying the application of the Model Rules and implementing the "side-by-side agreement" reached in June 2025 within the G7, which will be applicable from 2026 to multinational groups whose ultimate parent company is in the United States.

In Brazil, Law No. 15,079, of December 27, 2024, introduced Pillar 2 in accordance with the Global Anti-Base Erosion Rules (GloBE Rules), through the institution of the Additional Social Contribution on Net Profit (CSLL), and became regulated by acts of the Special Secretariat of the Federal Revenue of Brazil of the Ministry of Finance in order to qualify as a qualified minimum tax (Qualified Domestic Minimum Top-up Tax - QDMTT). The Pillar 2 rules came into effect in Brazil from 2025 and must be calculated based on the adjusted taxes covered and the adjusted profits of all constituent entities of the same multinational group in Brazil.

The simplified rules (safe harbors) imply that the Additional CSLL is not due provided that any of the following conditions are met: (i) the effective rate calculated based on information from the Country-by-Country Reporting exceeds 16% in 2025 and 17% in 2026; (ii) the presence of the multinational group in a jurisdiction is not relevant when revenue is less than €10 million and profit before tax is less than €1 million; or (iii) profit before tax is less than the sum of tangible fixed assets and personnel expenses, adjusted by a certain percentage that varies annually.

The assessment of potential exposure to the Additional CSLL (Social Contribution on Net Income) is based on the most recent tax returns, the country-by-country report, and the financial statements of the Group's constituent entities in Brazil. Based on the assessment, the effective rates of the Additional CSLL in Brazil are higher than 15%, therefore, no potential exposure arises.

**c.2) New standards and interpretations in force in future years**

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Amendments to IFRS 9 and IFRS 7 - Amendments to the Classification and Measurement of Financial Instruments:** To address issues identified during the post-implementation review of the classification and measurement requirements of IFRS 9 - Financial Instruments. The amendments are effective for reporting periods beginning on or after January 1, 2026. The Bank has not identified any material impacts from this change.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **IFRS 18 – Presentation and Disclosure in Financial Statements:** Replaces IAS 1 – Presentation of Financial Statements. IFRS 18 introduces new subtotals and three categories for income and expenses (operating, investing and financing) in the income statement structure. It also requires companies to disclose explanations of management-defined performance measures related to the income statement.

These changes are effective for fiscal years beginning January 1, 2027. Santander is evaluating the impacts of this change.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Amendments to IFRS 7, IFRS 18, IAS 1, IAS 8, IAS 36 and IAS 37 -** Disclosures on Uncertainties in Financial Statements: This amendment introduces illustrative examples that reinforce the application of existing IFRS requirements for disclosing the effects of relevant uncertainties in financial statements, particularly those arising from climate risks and the transition to a low-carbon economy. The amendment emphasizes the need for greater transparency regarding materiality judgments, key assumptions, and significant sources of estimation uncertainty that may affect assets, liabilities, results, and cash flows. The changes do not introduce changes to recognition or measurement criteria, focusing instead on improving the disclosures already provided for, especially in IFRS 18 (which will replace IAS 1), IFRS 7, IAS 8, IAS 36, and IAS 37, reinforcing the consistency and alignment between financial information and the effects of climate risks and other relevant uncertainties, when material, in the financial statements. The amendments are effective for reporting periods beginning on or after January 1, 2027. Santander is evaluating the impacts of this change.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Amendment to IAS 21 -** Translation for a Hyperinflationary Presentation Currency: clarifies the procedures to be applied when an entity begins presenting its financial statements in a hyperinflationary presentation currency, as defined in IAS 29. The amendment defines how comparative amounts and balances should be translated when this change occurs, aiming to ensure that the information remains relevant, consistent, and comparable over time. The amendments do not alter the recognition or measurement criteria, but merely clarify the translation requirements set forth in IAS 21, including retrospective application and the treatment of the effects of inflation in the presentation currency. The impacts are concentrated exclusively on the disclosures and the form of presentation of the financial statements, without affecting the entity's performance or financial position. The amendment is effective for reporting periods beginning on or after January 1, 2027. Santander is evaluating the impacts of this amendment.

**c.3) Estimates used**

The consolidated results and the determination of the consolidated equity are impacted by accounting policies, assumptions, estimates, and measurement methods used by the Bank's management in the preparation of the financial statements. The Bank makes estimates and assumptions that affect the reported values of assets and liabilities for future periods. All required estimates and assumptions, in accordance with IFRSs, represent management's best estimate pursuant to the applicable standard.

In the consolidated financial statements, estimates are made by the Bank's and the consolidated entities' Management to quantify certain assets, liabilities, income, and expenses, as well as to disclose notes to the financial statements.

**c.3.1) Critical estimates** 

The critical estimates and assumptions that have the most significant impact on the accounting balances of certain assets, liabilities, revenues, and expenses, and on the disclosures in the notes to the financial statements, are described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**i.** **Assessment of the fair value of certain financial instruments** 

Financial instruments are initially recognized at fair value, and those not measured at fair value through profit or loss are adjusted for transaction costs.

Financial assets and liabilities are subsequently measured at the end of each period using valuation techniques. This calculation is predicated on assumptions that take into account Management's judgment based on information and prevailing market conditions on the balance sheet date.

Banco Santander classifies fair value measurements using the fair value hierarchy that reflects the model employed in the measurement process, segregating financial instruments into Level I, II, or III.

**Notes 2.e and 46.c.8** detail the accounting treatment and sensitivity analysis pertaining to Financial Instruments, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**ii.** **Provisions for losses on credits due to impairment** 

The carrying value of non-recoverable financial assets is adjusted by recording a provision for loss under "Losses on financial assets (Net) – Financial Assets Measured at Amortized Cost" in the consolidated income statement. Reversals of previously recognized losses are recorded in the consolidated income statement in the period when the impairment decreases, provided there is an objectively verifiable recovery event.

When measuring the impairment loss on individually assessed loans, the Bank takes into account a range of factors related to the counterparty's condition, such as their economic and financial situation, indebtedness level, income-generating capacity, cash flow, management, corporate governance, and quality of internal controls, payment history, industry experience, contingencies, and credit limits, as well as asset characteristics, such as their nature and purpose, type, liquidity level sufficiency, and guarantees of total credit value, and also drawing on historical impairment experience and other circumstances known at the time of assessment.

**\*Values expressed in thousands, except when indicated**<br>

To measure the impairment loss on loans assessed collectively for impairment, the Bank segregates financial assets into groups considering their credit risk characteristics and similarities, that is, according to the segment, type of assets, collateral, and other factors associated with historical impairment experience and other circumstances known at the time of assessment.

**Notes 2.h and 46.b.2** detail the accounting treatment and credit risk assessment methods, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**iii.** **Provisions, contingent assets and liabilities** 

Provisions for legal and administrative proceedings are set up when the risk of loss in the legal or administrative action is assessed as probable and the amounts involved can be measured with sufficient certainty, based on their nature.

Explanatory note **2.q** presents information and any significant changes to the provisions and contingent assets and liabilities of the Bank between December 31, 2025 and December 31, 2024.

**c.4) Change of business Strategy**

In the first quarter of 2025, Banco Santander changed the way it manages part of its portfolio of pre-and post-fixed government securities, financial instruments that are part of its portfolio called ALCO (assets and liability management). The new strategy is based on a long-term investment profile, aiming to ensure greater financial stability, avoiding volatility in the Bank's equity (including for prudential purposes).

Management adopted the Amortized Cost (AC) accounting classification for part of the ALCO portfolio, which better reflects the objective of the business model strategy, see note 6.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Accounting policies and determination criteria** 

The accounting policies and calculation criteria used in preparing the consolidated financial statements were as follows:

**a) Functional and presentation currency**

Banco Santander's consolidated financial statements are presented in Reais, the functional currency of the entities and the presentation currency of these statements.

For each subsidiary, foreign entity and investment in an unconsolidated company, Banco Santander has defined the functional currency. The assets and liabilities of these entities are translated as follows:

- assets and liabilities are translated at the exchange rate on the balance sheet date.

- revenues and expenses are translated at the average monthly exchange rate.

- translation gains and losses on net investment are recorded in the statement of comprehensive income, under the "exchange rate variation on investees located abroad" line.

**b) Basis for consolidation**

**i. Subsidiaries**

The term "Subsidiaries" refers to entities that are under the Bank's control. This control is based on the Bank's: i) power over the invested entity; ii) exposure or entitlement to variable returns deriving from its relationship with the invested entity, and iii) ability to use its power to influence the level of returns, as established by legal, statutory, or contractual provisions.

Subsidiary consolidation takes place when the Bank secures control over the subsidiary and ends upon the loss of control. Notably, the income and expenses of a subsidiary that is either acquired or divested during the fiscal year are incorporated in the income statement and Other Comprehensive Income from the date on which the Bank acquires control to the point when it no longer exercises control over the subsidiary.

The result and each component of Other Comprehensive Income are attributed to the controllers of the Bank and to the non-controlling interests even if the effect is assigned to the non-controlling interests. The total comprehensive income of the subsidiaries is attributed to the owners of the Bank and to the non-controlling interests, even if this results in a negative balance for the non-controlling interests. All transactions, balances, income, and expenses between the companies of the Santander Conglomerate are fully eliminated in the consolidated financial statements.

Any changes to Santander Conglomerate's stakes in controlled entities that do not result in a loss of control over the subsidiaries are recorded as equity transactions. The difference between the value at which the non-controlling interests are adjusted and the fair value of the considerations paid or received is recorded directly in equity and attributed to the owners of the Company.

When the Bank loses control of a subsidiary, the gain or loss is recognized in the income statement and is determined by the difference between: (i) the sum of the fair value of the considerations received and the fair value of the residual interest; and (ii) the previous balance of the subsidiary's assets (including goodwill) and liabilities, and non-controlling interests, if any. All values previously recognized in "Other Comprehensive Income" related to the subsidiary are accounted for as if the Bank had directly disposed of the corresponding assets or liabilities of the subsidiary (i.e., reclassified to profit or loss or transferred to another shareholders' equity account, as required or permitted by the applicable IFRSs). The fair value of any investment held in the former subsidiary at the date of loss of control is considered as the fair value upon initial recognition for subsequent accounting under IFRS 9 Financial Instruments or, where applicable, the cost upon initial recognition of an investment in an associate or joint venture.

**\*Values expressed in thousands, except when indicated**<br>

**ii. Interests in joint ventures (entities under joint control) and associates**

Joint ventures are equity interests in entities that are not subsidiaries, yet are jointly controlled by two or more unrelated entities. This joint control is manifested in contractual arrangements in which two or more entities ("venturers") acquire interests in entities ("jointly controlled entities") or own operations or hold assets, such that the strategic financial and operational decisions affecting the joint venture are contingent upon the unanimous decision of the venturers.

Associates are those entities over which the Bank has the ability to exert significant influence (significant influence is the power to partake in the decision-making regarding the financial and operational policies of the invested entity) but lacks control or joint control.

In the consolidated financial statements, the interests in jointly-controlled entities and investments in associates are accounted for using the equity method, that is, the Bank's share in the net assets of the invested entity, taking into account dividends received from the eliminations of capital and other derivatives. Pertinent details regarding the entities accounted for using the equity method by the Bank are disclosed in **note 11**.

**iii. Mergers, acquisitions, and company disposals**

A business combination refers to the amalgamation of two or more separate entities or economic units into a single entity or a group of entities, accounted for in accordance with IFRS 3 – "Business Combinations".

Business combinations are carried out in such a way that the Bank gains control of an entity and are accounted for as follows:

• The Bank calculates the cost of the business
combination, defined as the fair value of the assets offered, the liabilities incurred, and the equity instruments issued, if applicable.

• The fair values of the assets, liabilities,
and contingent liabilities of the acquired entity or business, including intangible assets not recognized by the acquired entity, are
estimated on the acquisition date and recognized in the consolidated balance sheet.

• The surplus of the acquisition cost over
the fair value of the identifiable net asset acquired is recognized as goodwill (**note 13**). The surplus of the fair value of the
identifiable net assets over the acquisition costs is regarded as an advantageous purchase and is recognized in the income statement on
the acquisition date.

**Note 3** outlines the most significant transactions that took place in 2025 and 2024.

**iv. Investment Funds**

This encompasses the Investment Funds in which the Bank and its subsidiaries hold a substantial stake or the entirety of their shares, and over which the Bank and its subsidiaries are exposed, or have the right to variable returns and have the ability to influence these returns through decision-making power, in accordance with IFRS 10 – Consolidated Financial Statements, and are therefore consolidated in these Consolidated Financial Statements.

**c) Definitions and classification of financial instruments**

**i. Definitions**

"Financial instrument" is defined as any agreement that creates a financial asset in one entity and concurrently a financial liability or equity interest in a different entity.

"Equity instruments" are any contracts representing a residual equity interest in the assets of the issuing entity after all its liabilities have been deducted.

**\*Values expressed in thousands, except when indicated**<br>

"Derivative" is a financial instrument whose value changes in response to fluctuations in an observable market variable (such as interest rates, currency exchange rates, financial instrument prices, market indices, or credit ratings), where the initial investment is considerably lower relative to other financial instruments that react comparably to shifts in market factors, and is typically settled at a future date.

"Hybrid financial instruments" are agreements that simultaneously encompass a non-derivative main contract and a derivative, termed an embedded derivative, which is non-transferable on its own and has the effect of causing part of the cash flows from the hybrid contract to fluctuate in a manner similar to that of a standalone derivative.

The following transactions are not treated for accounting purposes as financial instruments:

• Investments in subsidiaries, jointly-controlled entities, and associates (**notes 3 and 11**).

• Rights and obligations arising from employee benefit plans (**note 21**).

**ii. Classification of financial assets for measurement purposes**

Financial assets are initially classified into various categories for management and measurement purposes, except when it is mandatory to report them as "Non-current assets held for sale," or in cases pertaining to "Cash and cash equivalents," "Derivatives used as hedging instruments," and "Investments in associates," all of which are accounted for separately.

Financial assets are, for measurement purposes, included in one of the following categories:

**• Financial assets measured at fair value through profit or loss:** this category includes financial assets acquired with the intention of generating short-term profit from their price fluctuations and financial derivatives not classified as hedging instruments, where the Bank's primary business model is to engage in frequent trading, financial assets that did not meet the criteria established in the SPPI Test (principal and interest payments only) and financial assets for which the Fair Value Option was made at the time of initial designation.

**• Financial assets measured at fair value in Other Comprehensive Income:** are financial assets that meet the SPPI criteria, the objective of which is to maintain the assets to receive contractual cash flows and also for sale.

Results arising from changes in fair value are recognized in the market value adjustment item in equity, with the exception of losses due to impairment, which are recognized in profit or loss. When a financial asset is disposed of or shows signs of a decline in fair value due to non-recovery, the result previously accumulated in the fair value adjustment account in equity is reclassified to profit or loss.

**• Financial assets measured at amortized cost:** this category includes financing granted to third parties, based on their nature, regardless of the type of borrower and the form of financing, including financial leasing transactions in which the entities included in the consolidation act as lessors. The entities included in the consolidation generally have a business model of holding the loans and credits they grant until their final maturity, which are therefore presented in the consolidated balance sheet at amortized cost (which includes the necessary adjustments to reflect estimated impairment losses).

**iii. Classification of financial assets for presentation purposes**

Financial assets are classified by nature under the following line items of the consolidated balance sheet:

• "Cash and Cash Equivalents"
and "Compulsory deposits with the Brazilian Central Bank": cash balances and demand deposit credit balances with Brazil's
Central Bank ("Bacen").

• "Financial assets measured at amortized
cost": this includes loans granted by the Bank, as well as financial leasing credits and other outstanding balances of financial
nature owed to the Bank, such as checks drawn on financial institutions, credit balances with clearing houses and settlement agencies
for stock exchange and organized market transactions, bonuses paid in cash, capital calls, fees and commissions receivables for financial
guarantees, and outstanding balances resulting from transactions not originated through banking operations and services, such as rent
collections and similar items.

• "Loans and other receivables from
credit institutions": credits of any kind in the name of financial institutions.

• "Loans and advances to customers":
this includes outstanding balances of all other credits and loans granted by the Bank, including transactions conducted in the open market
through centralized counterparties.

**\*Values expressed in thousands, except when indicated**<br>

• "Debt instruments": bonds and
other securities that constitute a debt obligation for the issuer, yield interest, and are issued in either physical or book-entry form.

• "Equity instruments": financial
instruments issued by other entities, such as shares, which are of an equity nature for the issuer, excluding investments in subsidiaries,
jointly-controlled entities, or associates.

• "Derivatives": this includes
the fair value in favor of the Bank from derivatives that are not categorized as hedging instruments.

• "Derivatives used as hedging instruments":
this includes the fair value in favor of the Bank from derivatives assigned as hedging instruments.

• "Investments in associates and joint
ventures": this includes investments in jointly-controlled entities or associates.

**iv. Classification of financial liabilities for measurement purposes**

Financial liabilities are classified, for measurement purposes, into one of the following categories:

• Financial Liabilities Measured at Fair Value through Profit or Loss: this category includes financial liabilities issued to generate short-term profit from their price fluctuations, financial derivatives not considered as hedge accounting, and financial liabilities arising from the direct sale of financial assets acquired under repurchase agreements or borrowed ("Short positions").

• Other financial liabilities at fair value through profit or loss: financial liabilities are included in this category when more relevant information is obtained, either by eliminating or significantly reducing recognition or measurement inconsistencies ("accounting differences") arising from the measurement of assets or liabilities or from the recognition of gains or losses on them on different bases, or because there is a group of financial liabilities or financial assets and liabilities that is managed and whose performance is assessed based on fair value, in accordance with a documented risk management or investment strategy, and information about the Bank is provided to the Bank's key management professionals on the same basis.

• Financial liability at amortized cost: financial liabilities, regardless of their form and maturity, not included in any of the previous categories and arising from financing activities undertaken by financial institutions.

**v. Classification of financial liabilities for presentation purposes**

Financial liabilities are classified by nature under the following line items in the consolidated balance sheet:

• "Deposits from credit institutions": deposits of any kind, including liabilities from loans and on-lending as well as funding raised in the open market, received from credit institutions.

• "Customer deposits": this includes deposits of any kind such as demand, savings, and time deposits, as well as open market transactions, received from customers.

• "Liabilities arising from securities": this includes the value of bonds and other debt represented by tradable securities, except for subordinated liabilities.

• "Derivatives": this includes the negative fair value balance of the Bank's derivatives that are not part of hedge accounting.

• "Short positions": this includes the value of financial liabilities arising from the direct sale of financial assets acquired under repurchase agreements or borrowed.

• "Capital-eligible debt instruments": the value of financing received which, in terms of payment priority, rank below ordinary debt. This category also encompasses financial instruments issued by the Bank which, despite being shares for legal purposes, do not satisfy the criteria to be categorized as equity.

• "Other financial liabilities": this includes the value of payment obligations characterized as financial liabilities not accounted for under other line items and liabilities subject to financial guarantee agreements, excluding those classified as questionable settlement.

• "Derivatives used as hedging instruments": this includes the fair value of the Bank's liabilities from derivatives assigned as hedging instruments.

• "Equity instruments": financial instruments issued by other entities, such as shares, which are equity instruments for the issuer, except investments in subsidiaries, jointly controlled entities or associates.

**\*Values expressed in thousands, except when indicated**<br>

**d) Funding, issuances, and other liabilities**

Funding instruments are initially recorded at their fair value, which is essentially regarded as the transaction price. They are subsequently measured at amortized cost (on an accrual basis) with its inherent expenses recognized as a financial cost.

Within the initial liability recognition criteria, attention should be given to composite instruments, which are classified as such because they comprise both a debt instrument (liability) and an embedded shareholders' equity component (derivative).

The registration of a composite instrument involves the combination of (i) a main instrument, which is recognized as a genuine liability of the entity (debt), and (ii) an equity component (derivative convertible into ordinary shares).

The issuance of "Notes" must be recorded in a specific liability account and adjusted based on the contracted rates, and recalibrated due to the impact of exchange rate variation, when issued in a foreign currency. All remunerations related to these instruments, such as interest and currency fluctuations (difference between the functional currency and the currency in which the instrument was denominated), must be recognized as expenses for the period, in accordance with the accrual basis of accounting.

Pertinent information regarding the issuance of these capital-eligible debt instruments is described in **note 19**.

**e) Measurement of financial assets and liabilities and recognition of fair value changes**

In general, financial assets and liabilities are initially recognized at fair value, which is deemed equivalent, until proven otherwise, to the transaction price. Financial instruments not measured at fair value through profit or loss are adjusted for transaction costs. Financial assets and liabilities are subsequently measured at the end of each period as follows:

**i. Measurement of financial assets**

Financial assets are measured at fair value, without deduction for estimated transaction costs that might be incurred upon their disposal, except for financial assets measured at amortized cost, equity instruments whose fair value cannot be determined in a sufficiently objective manner, and financial derivatives that have equity instruments of this kind as their underlying and are settled by delivering such instruments.

The "fair value" of a financial instrument on a given date is the price that would be received from the sale of an asset or would be paid for the transfer of a liability in a voluntary exchange among market participants on the measurement date. The most objective and common benchmark for the fair value of a financial instrument is the price that would be paid for it in an active, transparent, and significant market ("quoted price" or "market price").

In the absence of a market price for a particular financial instrument, its fair value is estimated based on the valuation techniques commonly adopted by the international financial community, taking into account the specific characteristics of the instrument to be measured and, most importantly, the various types of risks associated with it.

All derivatives are recognized on the balance sheet at fair value from the transaction date. When the fair value is positive, they are recognized as assets; when negative, as liabilities. Changes in the fair value of derivatives since the transaction date are recognized in the "Gains (losses) on financial assets and liabilities" line item of the consolidated income statement. Specifically, the fair value of standard financial derivatives included in the portfolios of financial assets or liabilities measured at fair value through profit or loss is deemed equivalent to their daily quoted price; if, under exceptional circumstances, should it be unfeasible to ascertain the quoted price on a specific date, these derivatives are measured using methods similar to those employed for valuing derivatives traded in the over-the-counter market.

The fair value of over-the-counter traded derivatives is deemed to be the aggregate of the instrument's future cash flows, discounted to their present value on the measurement date (referred to as "present value" or "theoretical close"), employing commonly used financial market valuation techniques such as Net Present Value (NPV), option pricing models, and other methods.

"Financial assets measured at amortized cost" are measured at amortized cost utilizing the effective interest method. The "amortized cost" is the acquisition cost of a financial asset or liability, either increased or decreased, as applicable, by the principal repayments and cumulative amortization (included in the income statement) of the difference between the initial cost and the maturity value. In the case of financial assets, the amortized cost also includes any reductions for impairment or inability to collect. For financial assets measured at amortized cost that are subject to fair value hedging, the fair value changes of these assets associated with the hedged risk(s) are recognized in the income statement.

The effective interest rate is the rate that exactly discounts estimated future cash flows over the expected life of the financial instrument to the initial gross carrying amount. The effective interest rate includes transaction costs, premiums, discounts and other fees or points that are an integral part of the instrument's effective yield.

---

**\*Values expressed in thousands, except when indicated**<br>

The effective interest method applies to financial assets measured at amortised cost and to debt instruments measured at fair value through other comprehensive income (FVOCI).

Equity instruments are measured at fair value, with changes recognised either in profit or loss or in other comprehensive income, depending on the election made at initial recognition in accordance with IFRS 9.

The values at which financial assets are recognized correspond, in all material respects, to the Bank's maximum credit risk exposure as of the date of each financial statement. Furthermore, the Bank has secured guarantees and additional credit support to mitigate its exposure to credit risk, predominantly comprising mortgages, cash collateral, equity instruments, sureties, assets leased under leasing and rental agreements, assets acquired under repurchase agreements, securities lending, and derivatives.

**ii. Measurement of financial liabilities**

In general, financial liabilities are measured at amortized cost, as previously defined, except for those included under the line items "Financial liabilities measured at fair value through profit or loss" and "Other financial liabilities measured at fair value through profit or loss," as well as financial liabilities designated as hedging instruments, which are measured at fair value.

**iii. Recognition of fair value changes**

As a general rule, changes in the book value of financial assets and liabilities are recognized in the consolidated income statement. These are distinguished between those arising from the interest provisioning and similar gains - recognized under the line item "Interest and Similar Income" or "Interest and Similar Expenses," as applicable - and those derived from other factors, recognized at their net value under the line item "Gains (Losses) on Financial Assets and Liabilities (Net).

Adjustments due to fair value changes related to financial assets measured at fair value through Other Comprehensive Income are temporarily recognized in equity under the line item "Other Comprehensive Income." Items debited or credited to this account remain in the Bank's consolidated shareholders' equity until the respective assets are written off, at which point they are debited to the consolidated income statement.

**iv. Hedging transactions**

Hedge accounting aims to represent in the financial statements the effects of an entity's risk management activities that use financial instruments to manage exposures arising from specific risks that could affect the period's results or other comprehensive income.

For a hedge relationship to meet the requirements set out in IFRS 9, the following conditions must be met:

&nbsp;&nbsp;&nbsp;&nbsp;• Instruments that can be designated as hedging
instruments are all derivative financial instruments or non-derivative financial instruments measured at fair value through profit or
loss, or a combination of both. In the case of foreign exchange risk hedges, any type of non-derivative financial instrument may also
be designated, regardless of its measurement criterion;

&nbsp;&nbsp;&nbsp;&nbsp;• The elements that can be designated as covered
items are all those that consist of recognized assets or liabilities, commitments, highly probable anticipated transactions, and net investments
abroad;

&nbsp;&nbsp;&nbsp;&nbsp;• **Documentation**: At the beginning of
the hedging relationship, the designation and formal documentation of the hedging relationship must be carried out, which must include
the entity's risk management strategy and objective, the identification of the hedging instrument and the hedged item, the nature of the
hedged risk, the methodology for measuring effectiveness, which includes the analysis of sources of ineffectiveness and the hedging ratio.

The main sources of ineffectiveness, according to the risk covered, are:

&nbsp;&nbsp;&nbsp;&nbsp;• Interest rate risk: misalignments in time
horizons, principal, reset and payment dates, time value of options, as well as changes to the hedged item or hedging instrument;

&nbsp;&nbsp;&nbsp;&nbsp;• Currency risk: in addition to the factors
mentioned above, the difference between the interest rates of the two currencies, which represents the net cost or benefit of converting
cash flows between two currencies with different interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;• **Effectiveness:** The hedging relationship
must be effective; therefore, there must be an economic relationship between the hedged item and the hedging instrument, credit risk must
not exert a dominant effect on the value changes resulting from this economic relationship, and the hedging ratio must be consistent with
that actually used by the entity in its risk management.

Santander assesses these effectiveness requirements through:

&nbsp;&nbsp;&nbsp;&nbsp;• Demonstration of the economic relationship
between the hedged item and the hedging instrument through a qualitative test and, if not met, through quantitative tests that compare
the market value of the hedged items, corresponding to the hedged risk, with the value of the hedging instruments. Additionally, a prospective
quantitative test of the variations in the market values of the hedging
instrument and the hedged item is performed;

**\*Values expressed in thousands, except when indicated**<br>

&nbsp;&nbsp;&nbsp;&nbsp;• The calculation of the hedge ratio, which
corresponds to the relationship between the quantity of items effectively covered by Santander and the quantity of hedging instruments
effectively used;

&nbsp;&nbsp;&nbsp;&nbsp;• Assessment of the predominance of credit
risk, carried out through analysis of the credit risk exposure of the hedged items and hedging instruments.

Hedge accounting structures are classified and recorded according to the type of risk they cover, based on the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;• Fair value hedges: these are hedges against
exposure to changes in the fair value of the hedged item, attributable to a specific risk;

&nbsp;&nbsp;&nbsp;&nbsp;• The variations found in both the hedging
instruments and the hedged items (in relation to the hedged risk) are recognized directly in the profit or loss;

&nbsp;&nbsp;&nbsp;&nbsp;• When a fair value hedge is discontinued,
adjustments previously recognized in the hedged item are recognized in profit or loss using the effective interest rate method recalculated
on the date the hedge relationship is terminated and must be fully amortized by their maturity;

&nbsp;&nbsp;&nbsp;&nbsp;• In the case of fair value hedges of interest
rate risk in a portfolio of financial instruments (macro hedges), gains or losses arising from the measurement of
the hedging instruments are recognized directly in the consolidated income statement, while gains or losses arising from changes in the
fair value of the hedged amount (attributable to the hedged risk) are recognized in the consolidated income statement, with a corresponding
entry in the line items "Changes in the fair value of hedged items" of a portfolio hedged against interest rate risk (asset
or liability), as applicable;

&nbsp;&nbsp;&nbsp;&nbsp;• **Cash flow hedges**: these are coverages
of exposure to variability in cash flows attributable to a specific risk associated with the hedged item;

&nbsp;&nbsp;&nbsp;&nbsp;• The effective portion of the change in the
value of the hedging instrument is recorded, on a temporary basis, in equity, until the cash flow subject to the hedge affects the profit
or loss;

&nbsp;&nbsp;&nbsp;&nbsp;• From that point on, it will be recognized
in the consolidated income statement during the same period as the covered item, unless it is included in the cost of the non-financial
asset or liability, or if the anticipated transactions are recognized as non-financial assets or liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;• When a cash flow hedge is discontinued,
the accumulated result of the hedging instrument recognized in equity (while the hedge was effective) will continue to be recognized in
that item until the hedged transaction occurs, at which point it will be recognized in profit or loss, unless it is anticipated that the
transaction will not occur, in which case it will be recognized immediately in profit or loss;

&nbsp;&nbsp;&nbsp;&nbsp;• To measure ineffectiveness, Santander compares
the valuation of the hedging instrument with the valuation of the hedged item based on the hedged risk, using different methodologies
such as the proxy method or the hypothetical derivative method. The ineffective portion of cash flow hedging relationships is recognized
directly in the consolidated income statement, under the heading.

Bank Santander discontinues the accounting of hedge relationships when the hedging instrument expires, is sold, or when the hedge relationship becomes ineffective because it is no longer aligned with the risk management objective. In this case, the derivative is then considered a trading derivative.

If a hedging relationship ceases to meet the effectiveness requirements, but the risk management objective remains, Santander will assess the rebalancing or adjustment of the coverage level to once again meet the effectiveness requirements, without needing to discontinue the hedging relationship.

A hedging instrument is generally designated in its entirety, since the factors that contribute to its fair value are interdependent. However, IFRS 9 allows excluding certain parts of the fair value of a hedging instrument:

(i) separating the intrinsic value and the time value of an option and designating only the intrinsic value as a hedging instrument, this separation being mandatory if the intrinsic value is designated;

(ii) separating the forward element and the spot element of a forward contract and designating only the spot element as a hedging instrument, which will be determined for each hedging relationship; and

(iii) separating the foreign currency basis differential of a currency derivative and excluding it from the designation of the hedging instrument, which will be determined for each hedging relationship.

Separating these components improves the effectiveness of the hedge and allows for alternative accounting treatment for the excluded component, which consists of recognizing the changes in value in other comprehensive income, and recognizing this component in profit or loss according to the nature of the hedged item, either over a period of time or at the time the hedge transaction occurs.

In addition, if the entity manages the credit risk of all or part of a financial instrument through the use of credit derivatives, there is the option of designating a credit exposure at fair value in profit or loss, provided that this derivative matches the name and degree of subordination of the financial instrument to be hedged. This designation may be made at the initial recognition of the designated financial instrument or subsequently, and must be duly documented. From its designation, the changes in fair value (for all its risks, and not exclusively for credit risk) will be recognized in the consolidated income statement.

**f) Write-off of financial assets and liabilities**

**Financial Asset Write-Off**

The Bank writes off a financial asset when the contractual rights to the cash flows from the asset expire or when it transfers the rights to receive the contractual cash flows in a transaction in which substantially all risks and rewards associated with the financial asset's ownership are transferred, or in which the Bank neither transfers nor retains substantially all the risks and rewards of the financial asset's ownership and does not maintain control over the financial asset.

On derecognition of a financial asset, the difference between the carrying amount of the asset (or carrying amount allocated to the portion of the asset derecognized) and the sum of (i) the consideration received (including any new asset obtained, less any new liability assumed) and (ii) any accumulated gains or losses recognized in "Other Comprehensive Income" is recorded in profit or loss.

Any gains/losses accumulated and recognized in "Other Comprehensive Income" related to equity instruments measured at fair value through Other Comprehensive Income are not recorded in the profit and loss statement upon the disposal of these securities.

The Bank engages in transactions in which it transfers assets recognized on its balance sheet, but retains all or substantially all the risks and rewards of the transferred assets or a portion thereof. In these cases, the transferred assets are not written off. Examples of such transactions include the assignment of loan portfolios with joint liability. In transactions where the Bank neither retains nor substantially transfers all the risks and rewards of ownership of a financial asset and retains control of the asset, the Bank continues to recognize the asset based on the degree of its ongoing engagement, determined by the extent to which it is exposed to changes in the value of the transferred asset.

**Financial asset write-off due to credit assignment** 

The accounting treatment for the transfer of financial assets depends on the extent to which the risks and rewards associated with the transferred assets have been transferred to third parties:

If the Bank transfers substantially all the risks and rewards to third parties, execute an unconditional sale of financial assets, engage in the sale of financial assets under an agreement stipulating their repurchase at fair value on the repurchase date, conduct the sale of financial assets with a call option purchase or a put option sale that is significantly out of the money, or securitization of assets in which the transferor does not retain a subordinated debt or provide credit enhancement to the new holders, and other similar cases, the transferred financial asset is written off, and any rights or obligations retained or created in the transfer are recognized simultaneously.

If the Bank retains substantially all the risks and rewards associated with the transferred financial asset, such as financial asset sales under an agreement stipulating their repurchase at a fixed price or at the sale price plus interest, a securities lending agreement in which the borrower pledges to return the same assets or similar assets, and other similar situations, the transferred financial asset is not written off and continues to be measured using the same criteria as before the transfer. However, the following items are recognized:

A corresponding financial liability, for an amount equal to the consideration received; this liability is thereafter measured at amortized cost.

The revenue from the transferred financial asset not written down and any expense incurred with the new financial liability.

If the Bank does not transfer or substantially retain all the risks and rewards associated with the transferred financial asset - such as the sale of financial assets with a purchased call option or a written put option that is not significantly out of the money, securitization of assets in which the assignor retains a subordinated debt or another type of credit enhancement related to a portion of the transferred asset, and other similar scenarios - a distinction is then drawn as follows:

If the assignor does not retain control of the transferred financial asset, the asset is written off, and any rights or obligations retained or created in the transfer are recognized.

If the assignor retains control, it continues to recognize the transferred financial asset at a value equivalent to its exposure to value fluctuations and recognizes a financial liability associated with the transferred financial asset. The net carrying amount of the transferred asset and the corresponding liability is the amortized cost of the retained rights and obligations if the transferred asset is measured at amortized cost, or the fair value of the retained rights and obligations if the transferred asset is measured at fair value.

**Financial Liabilities Write-Off** 

The Bank writes off a financial liability when its contractual obligations are extinguished, annulled, or reach their maturity.

**g) Offsetting of assets and liabilities**

Financial assets and liabilities are offset, that is, recorded in the balance sheet at their net value, only if the Bank and its subsidiaries currently have a legally enforceable right to offset the recognized amounts and intend to settle on a net basis, or to realize the asset and settle the liability simultaneously.

Offsetting and Settlement Agreements for Obligations – IFRS 07 – Derivative Instruments (Disclosure) - Banco Santander has netting and settlement agreements for obligations within the National Financial System ("SFN"), signed with both natural and legal persons, whether part of the SFN or not, resulting in increased financial settlement assurance with the parties that have such agreements. These agreements stipulate that, in the event of counterparty default, the payment obligations to Banco Santander arising from credit and derivative transactions will be offset by Banco Santander's payment obligations to the counterparty.

The table below provides details of the financial assets and liabilities subject to offsetting as of December 31, 2025 and 2024:

**h) Non-recoverable financial assessment of financial assets**

**i. Definition**

A financial asset is deemed non-recoverable when objective evidence exists of events that:

• Cause an adverse impact on estimated future cash flows at the date of the transaction, in the case of debt instruments (loans and debt securities).

• Indicate that their book value cannot be fully recovered, in the case of equity instruments.

• Arise from the breach of loan agreement clauses or terms, and

• In the event of bankruptcy proceedings.

As a general rule, whenever the aforementioned events are observed, the carrying amount of non-recoverable financial assets is adjusted by recording a provision for loss as a debit to the expense under "Impairment losses on financial assets (net)" in the consolidated income statement. The reversal of previously recorded losses is recognized in the consolidated income statement in the period in which the impairment decreases and can be objectively associated with a recovery event.

**ii. Debt instruments recorded at amortized cost**

The value of a loss for the determination of the recoverable amount of a debt instrument measured at amortized cost is equal to the difference between its carrying amount and the present value of its projected future cash flows (excluding future credit losses not yet incurred), discounted at the financial asset's original effective interest rate (i.e., the effective interest rate calculated at initial recognition), presented as a reduction in the asset's balance and recognized in the income statement.

When projecting future cash flows for debt instruments, the following factors are taken into consideration:

• All values expected to be obtained over the residual life of the instrument, including, where applicable, the guarantees provided. The loss due to non-recovery further considers the likelihood of collecting provisioned interest receivables;

• The various types of risks to which each instrument is subject; and

• The circumstances under which collections are expected to be executed.

These cash flows are then discounted at the effective interest rate of the transaction.

**\*Values expressed in thousands, except when indicated**<br>

Specifically regarding the adjustment in the recoverable amount resulting from the materialization of the insolvency risk of counterparties (credit risk), a debt instrument is deemed non-recoverable due to insolvency when there is evidence of a deterioration in the counterparty's payment capacity, whether due to being overdue or for other reasons.

The Bank, through its risk management division, implements policies, methods, and procedures to mitigate its exposure to credit risk arising from insolvency attributable to counterparties.

These policies, methods, and procedures are applied in the issuance, examination, and documentation of debt instruments, contingent liabilities, and other commitments, in the identification of recoverable value, and in the calculation of the amounts needed to cover the respective credit risk.

The procedures applied in the identification, measurement, control, and mitigation of credit risk exposure are based on an individual level or grouped by similarity.

• Customers under individualized management: Wholesale clients, financial institutions, and certain companies. Risk management is performed through an analysis enhanced by decision-support tools that rely on internal risk assessment models.

• Customers under standardized management: this category includes individuals and entities not classified as individualized customers. The approach to risk management employs automated models for decision-making and assessing internal risk. These models are supplemented by specialized analyst teams in instances where the model's comprehensiveness or accuracy falls short. Loans associated with standardized customers are generally classified as non-recoverable when there is a historical record of losses and are overdue by more than 90 days.

With regard to the provision for credit risk impairment losses, the Bank assesses all loans. Loans are either assessed individually for impairment or assessed collectively for impairment. Loans recorded at amortized cost that are not assessed individually for impairment are assessed collectively for impairment and are grouped together considering similarity of risk. Loans assessed individually for impairment are not included in balances assessed collectively for impairment.

In assessing impairment losses on loans on an individual basis, the Bank takes into account the borrower's conditions, including their economic and financial status, level of indebtedness, capacity for income generation, cash flow, management, corporate governance, and the quality of internal controls, payment history, industry experience, contingencies, and credit limits, as well as other relevant characteristics pertaining to assets, including their nature and purpose, type, adequacy, and liquidity level guarantees, as well as the total credit value, and also based on historical experiences of impairment losses and other known circumstances at the time of assessment.

To calculate the impairment loss on loans collectively assessed for impairment, the Bank categorizes financial assets into groups based on their credit risk characteristics and similarities. This classification considers various factors, including the segment, type of assets, collateral, and other elements associated with the historical experience of impairment losses and other known circumstances at the time of assessment.

In certain instances, the observable data required to estimate the loss amount due to an impairment of a financial asset may be limited or may no longer be entirely relevant to the current circumstances.

In these instances, the entity employs its judgment-based experience to estimate the value of any impairment losses. Similarly, the entity utilizes its judgment-based experience to adjust the observable data for a group of financial assets to accurately reflect the current circumstances.

The impairment loss is calculated using statistical models that consider the following factors:

• Exposure at Default (EAD) - this is the amount of risk exposure on the date the borrower defaults. The duration of the default is incorporated into the calculation of the "Probability of Default" (PD).

• The EAD is based on the gross carrying amount at the reporting date and, where applicable, adjusted to reflect the expected exposure at the time of default in accordance with IFRS 9.

• Probability of Default (PD) - this is the likelihood that the borrower will not meet their obligations for principal and/or interest payments.

The Probability of Default is determined using a one-year time horizon for transactions classified under stage 1, as well as over the lifetime of the asset (stages 2 and 3); that is, it quantifies the probability of the borrower defaulting. A loan is considered to be in default if either the principal or interest is overdue by ninety days or more, or if the loan is outstanding and there are significant doubts regarding the counterparty's solvency (subjective doubtful assets).

**\*Values expressed in thousands, except when indicated**<br>

• Loss Given Default (LGD) - this refers to the loss incurred upon default.

The LGD calculation is based on the net write-offs of non-performing loans, factoring in the collateral associated with the loans, the income and expenses related to the recovery process, and the point in time when the default occurs.

• Loss Identification Period (LIP) - this refers to the interval between the occurrence of a loss event and the identification of evidence substantiating that loss. In other words, it delineates the time span from when a credit loss event occurs to when such loss is conclusively confirmed.

Furthermore, before writing off non-performing loans (which is done only after the Bank has exhausted all recovery efforts), a full provision is made for the remaining outstanding amount of the loan so that the loan loss provision fully covers the losses. Accordingly, the Bank understands that its loan loss provision methodology was developed to match its risk metrics and capture loans that could potentially show impairment.

**iii. Debt instruments or equity instruments classified as financial assets measured at fair value through Other Comprehensive Income**

The difference between the amortized cost and the fair value of debt instruments or equity instruments classified as financial assets measured at fair value through Other Comprehensive Income is recognized in equity, under the identically titled line item.

When there is objective evidence indicating that the previously mentioned differences are attributable to an impairment loss recognized due to a decline in fair value from non-recovery, these are no longer recognized in equity and are reclassified to the consolidated statement of profit or loss at the cumulative amount as of that date. Losses deemed permanent on an investment in equity instruments are not reversed in subsequent periods.

**i) Repurchase agreements**

Purchases (sales) of financial assets under a non-optional repurchase (repo) agreement at a fixed price are recognized in the consolidated balance sheet as investments (funding) in repurchase agreements, depending on the nature of the debtor (creditor), classified under the line items "Cash and Cash Equivalents and compulsory deposits with the Brazilian Central Bank," "Loans and other receivables from credit institutions," or "Loans and advances to customers", ("Deposits from credit institutions" or "Customer deposits").

Differences between purchase and sale prices are recognized as interest income over the contract period.

**j) Lease Accounting – IFRS 16**

**I. Lease Identification**

Upon adopting IFRS 16, the Bank recognizes lease liabilities in accordance with the principles of IFRS 16 - Leases.

The following exemptions from recognition are also being applied:

• Accounting for leases with a remaining lease term of less than 12 months as short-term leases;

• The accounting for leases of low-value underlying assets.

The Bank enters into leases for properties and equipment. Predominantly, the assets covered by these lease agreements are real estate properties associated with the branches.

Banco Santander does not hold any right-of-use assets that fall under the definition of investment properties.

**II. Lease term**

Lease agreements are formalized, analyzed, and renegotiated on an individual basis, encompassing a broad range of distinct terms and conditions. The Bank assesses the lease term, as well as its intention to continue occupying the properties. Consequently, lease term estimates may vary in accordance with contractual conditions, considering extension options and legal provisions.

**\*Values expressed in thousands, except when indicated**<br>

The Bank considers that penalties for early termination of contracts charged before the maturity date do not represent a significant component.

Lease agreements do not contain restrictive clauses, but leased assets cannot be used as collateral for loans.

**III. Initial Measurement**

Upon initial recording, leases are recognized as a right-of-use asset and a corresponding liability on the date the leased asset becomes available for use by the Group.

The right-of-use asset to be recognized is measured at its cost, counterbalanced by the lease liability, which represents the present value of the lease payments not yet made as of the date. Lease payments are discounted using the lessee's incremental borrowing rate. There are no onerous contracts that required an adjustment to the right-of-use assets to be recognized at the date of initial adoption.

The right-of-use assets are measured at amortized cost as per the following:

• The initial measurement value of the lease liability;

• Any lease payment made on or before the start date, net of any incentives received;

• Any initial costs directly attributable; and

• Restoration costs, if the criteria of IAS 37 are fulfilled for the recognition of Provisions, Contingent Liabilities, and Contingent Assets.

The Santander Group adopts as the incremental borrowing rate the interest rate it would incur to borrow the necessary funds to obtain an asset of similar value to the leased asset, under equivalent terms, collateral, and economic conditions. This rate is represented within Santander Brasil by the funding cost curve of a free asset, applied on an individual basis to each lease agreement in accordance with the projected lease term estimates.

Lease liabilities include the net present value of the following lease payments:

• Fixed payments net of any incentive;

• Variable payments based on a rate or index;

• Payments expected to be made by the lessee, based on the residual value of guarantees;

• The exercise price of a call option, if the lessee has reasonable assurance about the option's exercise; and

• Penalty payments for lease termination if the lease term reflects the exercise of the option by the lessee.

Lease liabilities are primarily adjusted for inflation (IGP-M), with the estimated projections as of the base date of December 31, 2025 detailed below:

---

| | |
|:---|:---|
| **IGP-M forecast** | |
| Up to 3 months | 1.0% |
| From 3 to 12 months | 4.0% |
| From 1 year to 3 years | 4.0% |
| From 3 years to 5 years | 4.0% |
| Over 5 years | 4.0% |

**\*Values expressed in thousands, except when indicated**<br>

**IV. Subsequent Measurement**

After the initial measurement, the values of the assets recorded as right of use are being updated using the cost method, thus any accumulated depreciation is deducted monthly, in accordance with the criteria of IAS 16 - Fixed Assets on asset depreciation right of use and corrected any remeasurement of the lease liability, where applicable.

The lease liability initially recorded is updated monthly by increasing the amount of the liability for the interest portion of each lease agreement and reducing the amount of monthly lease payments and corrected for any lease remeasurement, when applicable.

The lease liability is remeasured, in the event of changes in the lease term or contract value, the amount resulting from the new determination of the lease liability is recorded as a contra entry to the corresponding right-of-use asset.

Use rights are subject to an impairment test.

**k) Non-current assets held for sale** 

Non-current assets held for sale comprise the carrying amount of individual items, or groups of assets designated for disposal, or items that are part of a business unit targeted for disposal ("Discontinued operations"), where the sale in their current condition is highly probable and expected to take place within one year. Real estate or other non-current assets acquired by the consolidated entities in full or partial settlement of their debtors' payment obligations are classified as non-current assets held for sale through auctions, which typically take place within one year.

Non-current assets held for sale are measured at whichever is lower between the fair value minus selling costs and the carrying amount at the date they are classified in this category. These assets are not subject to depreciation.

Impairment losses of an asset or disposal group due to a reduction in their carrying amount to fair value (minus selling costs) are recognized in "Gain/(Loss) on Disposal and Expenses for Non-Current Assets Held for Sale Not Classified as Discontinued Operations" in the consolidated statement of profit or loss. Gains from a non-current asset held for sale, arising from subsequent increases in fair value (minus selling costs), increase its carrying amount and are recognized in the consolidated statement of profit or loss up to the amount equivalent to the previously recognized impairment losses.

**I) Residual maturity periods and average interest rates**

The analysis of the maturities of the balances of certain items in the consolidated balance sheets at the end of the years 2025 and 2024 is reported in **note 43-d**.

**m) Tangible asset**

Tangible asset comprise the value of buildings, land, furniture, vehicles, computer hardware, and other equipment owned by the Bank. This category also includes tangible assets received by the Bank in full or partial settlement of financial assets representing receivables from third parties, which are intended for sustained use, as well as tangible assets acquired under finance leases, which are presented at their acquisition cost, minus their respective accumulated depreciation and any impairment losses (net book value exceeding the recoverable amount).

Depreciation is calculated using the straight-line method, based on the acquisition cost of the assets minus their residual value. Land on which buildings and other structures are situated has an indefinite useful life and, therefore, is not subject to depreciation.

The depreciation expense for tangible assets is recognized in the consolidated statement of income and is calculated primarily by applying the following depreciation rates (based on the average estimated useful life of the various assets):

---

| | |
|:---|:---|
|  | **Annual Rate** |
| Buildings for own use | 4% |
| Furniture | 10% |
| Fixtures | 10% |
| Office and IT equipment | 20% |
| Improvements on third-party properties | 4% or until the contract's expiration date |

**\*Values expressed in thousands, except when indicated**<br>

At the end of each reporting period, the Bank assesses whether there are any indications that its tangible assets may be subject to impairment, that is, when an asset's carrying amount exceeds its recoverable amount, whether through use or sale.

Once a reduction in the recoverable amount of the tangible asset is identified, it is adjusted to its recoverable amount by recognizing an accounting loss for the reduction in its recoverable amount, recorded under 'Impairment losses on other assets (net).' Furthermore, the depreciation value of said asset is recalculated to adjust the value of the asset's useful life.

In cases where there is evidence or indication of a recovery in the value of a tangible asset, the Bank recognizes the reversal of the impairment loss previously recorded and must adjust future depreciation expenses in line with the asset's remaining useful life. Under no circumstances may the reversal of an impairment loss on an asset increase its carrying amount beyond what it would have been had no impairment loss been recognized in prior periods.

Maintenance and preservation expenses for self-used fixed assets are recognized as expenses in the period in which they are incurred.

**n) Intangible assets**

Intangible assets are identifiable non-monetary assets (separable from other assets) without physical substance, arising from business combinations or internally developed software, with either a finite or indefinite useful life. Recognition is limited to those assets whose acquisition cost can be reliably measured and for which the consolidated entities deem it probable that future economic benefits will be generated.

Intangible assets are initially recognized at their acquisition or production cost and are subsequently measured net of any accumulated amortization and any impairment losses.

**I. Goodwill**

In the acquisition of an investment in a subsidiary, any difference between the investment cost and the investor's share in the net fair value of the identifiable assets, liabilities, and contingent liabilities of the invested entity (whether a subsidiary or an associate) is recognized in accordance with IFRS 3, 'Business Combinations'.

Goodwill is recognized only when the amount of the consideration acquired from the investee exceeds the fair value at the date of acquisition, and therefore represents a payment made by the acquirer in anticipation of future economic benefits from assets of the acquired entity that cannot be individually identified and separately recognized.

Annually or whenever there is any indication of loss to recoverable value, goodwill is tested for impairment (recoverability test) and if any loss exists, goodwill is written off and recognized as Losses on other assets (net) - Other intangible assets in the Consolidated Statement of Income.

Adjustments to the net fair value of identifiable assets, liabilities, and contingent liabilities of the invested entity in comparison to their carrying amount are individually allocated to the acquired identifiable assets and the assumed liabilities based on their respective fair values at the acquisition date.

In instances of business combinations executed in stages, the previously held equity interest in the acquired entity is remeasured at its fair value on the acquisition date at which control of said acquired entity is secured.

**II. Other intangible assets**

This represents an identifiable, non-monetary asset that lacks physical substance. It primarily originates from software development and the acquisition of rights capable of generating economic benefits for the Bank. These assets may possess either a finite or indefinite useful life.

Other intangible assets are classified as having an indefinite useful life when, following a comprehensive analysis of all relevant factors, it is determined that there is no foreseeable limit to the period during which the asset is expected to generate cash inflows for the Bank. In all other instances, these assets are considered to have a finite useful life.

**\*Values expressed in thousands, except when indicated**<br>

Intangible assets with an indefinite useful life are not amortized: at the end of each reporting period, the entity reviews the classification as having an indefinite useful life. If this classification is maintained, these assets are subject to annual impairment tests to determine their recoverable amount (IAS36).

Intangible assets with a defined useful life are amortized over their useful life using methods similar to those applied for depreciating tangible assets. The amortization expense is recognized under the line item "Depreciation and Amortization" in the consolidated statement of income.

At the end of each reporting period, the Bank assesses whether there are any indications that intangible asset items may have suffered an impairment, that is, an asset whose carrying amount exceeds its recoverable amount. Should any impairment be identified, the asset is adjusted to its recoverable amount.

The measurement of the recoverable amount of other intangible assets - such as software - is conducted based on their value in use, as well as an analysis of the asset's discontinuation in relation to the Bank's operations.

Software acquisition and development costs are amortized over a maximum period of 5 years.

**o) Other assets**

This includes advances and accrued income (excluding accrued interest), intangible assets related to acquired customer relationships, any net pension asset recognised in the consolidated balance sheet, and other amounts not classified in specific line items.

The recoverability of intangible assets arising from acquired customer relationships is assessed based on value in use, as it is not possible to reliably determine fair value less costs of disposal due to the absence of an active market or observable parameters to estimate a disposal value.

Value in use is determined based on projected future cash flows attributable to the asset or the relevant cash-generating unit, discounted to present value using reasonable and supportable assumptions. The projections are reviewed quarterly, considering actual performance and updated assumptions. The resulting recoverable amount is compared with the carrying amount to determine whether any impairment loss should be recognised.

**p) Insurance contracts**

Insurance contracts issued by the Bank are assessed at initial recognition to determine whether they are onerous, in accordance with IFRS 17. A group of insurance contracts is considered onerous if the fulfilment cash flows, including any previously recognised acquisition cash flows, exceed the consideration received, resulting in a net outflow.

When a group is identified as onerous, a loss is recognised in profit or loss, and the contractual service margin for that group is set to zero, with the carrying amount of the liability equal to the fulfilment cash flows.

The Bank chooses to present, in other comprehensive income, the variations resulting from changes in the discount rates applied to the measurement of insurance contract liabilities, as permitted by IFRS 17.

**q) Provisions for judicial and administrative proceedings, commitments, and other provisions**

Banco Santander and its subsidiaries are engaged in judicial and administrative proceedings related to tax, labor, and civil matters, stemming from the ordinary course of their operations.

Provisions are reassessed at each balance sheet date to reflect the most accurate current estimate and may be fully or partially reversed or reduced when it becomes improbable that resource outflows and related obligations will occur. This includes situations such as the expiration of legal deadlines, the issuance of final judgments in legal proceedings, among others.

Judicial and administrative provisions are recognized when the risk of loss from judicial or administrative proceedings is assessed as probable, and the amounts involved can be estimated with sufficient certainty based on the nature, complexity, and historical outcomes of the proceedings, as well as the opinions of both internal and external legal advisors and the best available information. For cases where the risk of loss is considered possible, provisions are not recognized, but the relevant information is disclosed in the notes to the financial statements. For cases where the risk of loss is deemed remote, disclosure is not required.

**\*Values expressed in thousands, except when indicated**<br>

Contingent assets are not recognized in the accounting records, except in instances where there are tangible guarantees or favorable judicial rulings, with no possibility for further appeals, thereby rendering the gain as virtually certain. Contingent assets that have a probable likelihood of success, if any, are solely disclosed in the financial statements.

In cases of final judgments rendered in favor of Santander, the counterparty is entitled, upon fulfilling specific legal criteria, to initiate a rescission action within a timeframe prescribed by the legislation in effect. Rescission actions are treated as new legal proceedings and will be assessed for contingent liabilities if, and when, they are filed.

**r) Other liabilities**

Other liabilities include the balance of all accrued expenses and deferred income, excluding accrued interest, and the value of any other liabilities not classified under other categories.

**s) Share-based compensation**

The Bank has established long-term compensation plans with specific vesting conditions. These vesting conditions include: (i) service conditions, requiring that the participant remains employed throughout the vesting period; (ii) performance conditions, where the number of shares to be allocated to each participant is determined based on the evaluation of a performance metric of the Bank: the comparison of the Total Shareholder Return (TSR) of the Santander Conglomerate with the TSR of the Bank's main global competitors; and (iii) market conditions, as certain parameters are linked to the fair value of the Bank's shares. The Bank determines the fair value of the services provided by referencing the fair value of the equity instruments granted on the date of grant, taking into account the market conditions for each plan when estimating fair value.

**Stock Settlement**

The Bank measures the fair value of the services provided by referencing the fair value of the equity instruments granted on the grant date, factoring in market conditions for each plan when estimating fair value. To recognize personnel expenses against capital reserves over the vesting period, as services are received, the Bank considers the treatment of service conditions and recognizes the amount for services received during the vesting period, based on the most accurate estimate of the number of equity instruments expected to be granted.

**Cash Settlement**

For cash-settled share-based payments (in the form of share appreciation), the Bank measures the services provided and the corresponding liability incurred at fair value. This process captures the share appreciation from the grant date to the settlement date. The Bank reassesses the fair value of the liability at the end of each reporting period, and any changes in this amount are recognized in the period's results. To recognize personnel expenses against provisions for "salaries payable" throughout the vesting period, reflecting the receipt of services, the Bank records the total liability representing the best estimate of the number of share appreciation rights expected to be granted at the end of the vesting period and recognizes the value of services received during the vesting period, based on the best available estimate. The Bank periodically reviews its estimate of the number of share appreciation rights that will be granted at the end of the vesting period.

**t) Recognition of income and expenses**

The key criteria employed by the Bank for the recognition of its income and expenses are summarized below:

**i. Interest and similar income and expenses**

Interest and similar income and expenses are generally recognized on an accrual basis, using the effective interest rate method.

---

**\*Values expressed in thousands, except when indicated**<br>

**ii. Commissions, fees, and similar items**

Fees and commission income and expenses are recognized in the income statement using criteria that vary according to their nature (**notes 34 and 35**). The key criteria are as follows:

• Fee and commission income and expenses, associated with financial assets and financial liabilities measured at fair value through profit or loss, are recognized upon payment;

• Those arising from transactions or services provided over a period of time are recognized over the duration of these transactions or services; and

• Those related to services provided in a single transaction are recognized at the time the transaction is executed.

**iii. Non-financial income and expenses**

For accounting purposes, they are recognized on an accrual basis.

**iv. Deferred collections and payments**

Recognized for accounting purposes at the carrying amount derived from discounting expected cash flows at market rates.

**v. Loan arrangement fees**

Loan arrangement fees, including application and origination fees, are accrued and recognized in the income statement over the term of the loan. Specifically, for origination fees, the portion attributable to direct costs incurred in the loan contract is immediately recognized in the consolidated income statement.

**u) Guarantees**

**u.1) Financial Guarantees**

Financial guarantees are defined as contracts whereby an entity commits to making specific payments on behalf of a third party should that party fail to do so, irrespective of the various legal forms they may assume, including but not limited to guarantees, irrevocable documentary credits issued or confirmed by the entity, among others.

The Bank initially recognizes the fees associated with financial guarantees as liabilities on the consolidated balance sheet at fair value. This fair value is typically the present value of the fees, commissions, or interest expected to be received from these contracts over their term.

Financial guarantees, irrespective of the guarantor, the instrument, or any other circumstances, are subject to periodic reviews to assess the credit risk exposure and, where necessary, to determine the need for a provision. Credit risk is evaluated by employing criteria similar to those used for quantifying impairment losses on debt instruments measured at amortized cost.

The provisions established for these transactions are recognized under the line item "Provisions for Judicial and Administrative Proceedings, Commitments, and Other Provisions" in the consolidated balance sheet (**note 22**).

If a specific provision is required for financial guarantees, the corresponding commissions to be allocated are recognized under the line item "Financial liabilities at amortized cost - Other financial liabilities" in the consolidated balance sheet and are reclassified to the appropriate provision.

**u.2) Guarantees and Credit Risk Mitigation Policy**

Banco Santander performs credit risk management by utilizing guarantees in its operations. Each business unit is responsible for managing credit risk and formalizes the use of collateral in its credit policies.

Banco Santander employs guarantees to enhance its recovery capabilities in operations exposed to credit risk. The types of guarantees utilized include surety, property, legal structures with mitigation power, and offsetting agreements. Each year, the Bank conducts a review of its guarantee policies to reflect changes in the market, the characteristics of the assets pledged as collateral, and the conditions of these assets. These are examples of the technical parameters subject to review.

---

**\*Values expressed in thousands, except when indicated**<br>

Credit limits are continuously monitored and adjusted in response to customer behavior. Consequently, potential loss amounts constitute a fraction of total available funds.

**v) Assets under management, including investment and pension funds, managed by the Bank**

Assets owned by third parties and managed by the consolidated entities are not presented in the consolidated financial statements. Management fees are included in "Fee and commission income" in the consolidated income statement. **Note 43-b** contains information on the third-party assets managed by the Bank.

The investment funds and pension funds managed by the consolidated entities are not recorded in the consolidated financial statements since the related assets are owned by third parties. The fees and commissions earned in the year for the services rendered by the Bank entities to these funds (asset management and custody services) are recognized in the heading "Fee and commission income" in the consolidated income statement.

**w) Post-employment benefits** 

The post-employment benefit plans include the commitments made by the Bank to: (i) supplement the benefits of the public pension system; and (ii) provide medical assistance in the event of retirement, permanent disability, or death to eligible employees and their direct beneficiaries.

**Defined contribution plans**

The defined contribution plan is a post-employment benefit plan under which the Bank and its subsidiaries, as the sponsoring entities, contribute fixed amounts to a pension fund. There is no legal or constructive obligation for the sponsoring entities to make additional contributions if the fund lacks sufficient assets to fulfill all benefits associated with services rendered in the current and prior periods.

The contributions made in this regard are recognized as "Interest and Similar Expenses" in the income statement.

**Defined benefit plans**

The defined benefit plan is a post-employment benefit plan other than a defined contribution plan, as detailed in Note 21. Under this plan, the sponsoring entity is obligated to provide the agreed benefits to employees and therefore bears actuarial and investment risks.

The defined benefit obligation is measured using the projected unit credit method and discounted at a rate determined in accordance with IAS 19. Plan assets are measured at fair value.

Remeasurements, including actuarial gains and losses and the return on plan assets (excluding amounts included in net interest), are recognised immediately in other comprehensive income. The net defined benefit liability or asset represents the deficit or surplus of the plan recognised in the statement of financial position.

**Main Definitions**

- The present value of a defined benefit obligation represents the present value, excluding any deduction of plan assets, of the expected future payments required to settle the obligation arising from the employee's service in both the current and prior periods.

- Deficit or surplus represents: (a) the present value of the defined benefit obligation; minus (b) the fair value of the plan's assets.

The sponsoring entity may recognize the plan's assets on the balance sheet when they exhibit the following characteristics: (i) the fund's assets are sufficient to cover all obligations related to employee benefits of the plan or the sponsoring entity; or (ii) the assets are returned to the sponsoring entity with the objective of reimbursing it for benefits already disbursed to employees.

- Actuarial gains and losses are changes in the present value of the defined benefit obligation stemming from: (a) experience adjustments (impacts of differences between the actuarial assumptions adopted and the actual outcomes); and (b) the effects of changes in actuarial assumptions.

- The current service cost refers to the increase in the present value of the defined benefit obligation attributable to the employee's service during the current period.

- The past service cost corresponds to the change in the present value of the defined benefit obligation for services provided by employees in prior periods, resulting from amendments to the plan or a reduction in the number of employees covered.

**\*Values expressed in thousands, except when indicated**<br>

Post-employment benefits are recognized in the income statement under Interest Expenses and Similar Expenses and Provisions (Net).

Defined benefit plans are recognized based on an actuarial study, conducted annually by an external consulting firm at the end of each financial year, and are effective for the subsequent period.

**x) Other long-term employee benefits** 

Other long-term employee benefits, defined as obligations to early retirement beneficiaries - those who have ceased to render services to an entity but, without being legally retired, continue to hold economic rights with respect to the entity until they achieve legal retirement status - time-based bonuses for accounting purposes, as applicable, in accordance with the approach previously established for defined benefit post-employment plans, with the exception that all past service costs and actuarial gains and losses are recognized immediately (**note 21**).

**y) Termination benefits**

Termination benefits are recognized when a detailed formal plan, identifying the fundamental changes to be implemented, is in place. Recognition occurs provided that the implementation of the plan has commenced, its key features have been publicly announced, or objective facts concerning its implementation have been disclosed.

**z) Corporate Income Tax (IRPJ), Social Contribution on Net Profit (CSLL), Social Integration Program (PIS), and Contribution for the Financing of Social Security (COFINS)**

The income tax expense is derived from the sum of Income Tax, Social Contribution, PIS, and COFINS. The current Income Tax and Social Contribution are determined by applying their respective rates to taxable income, while the rates for PIS and COFINS are applied to their specific calculation bases as defined in the relevant legislation. This calculation also includes adjustments for changes in deferred tax assets and liabilities as recognized in the consolidated income statement. For income tax expenses resulting from transactions directly recognized in equity, the corresponding tax effect is likewise recognized in equity.

The Corporate Income Tax (IRPJ) liability is calculated at a rate of 15%, plus an additional 10%, applied to the profit after making the adjustments required by tax legislation. The Social Contribution on Net Profit (CSLL) is calculated at a rate of 15% for financial institutions, private insurance companies, and capitalization entities, and 9% for other businesses, levied on the profit after the adjustments required by tax legislation have been considered.

The Social Contribution on Net Income (CSLL) rate for all banks, financial institutions, private insurance companies, and capitalization entities (businesses operating within the financial sector) was increased by 1% for the base period from August 1, 2022 to December 31, 2022, as stipulated by Provisional Measure No. 1,115/2022.

The Social Integration Program (PIS) and the Contribution for the Financing of Social Security (COFINS) are calculated at a combined rate of 4.65% on certain gross revenues and expenses. Financial institutions are allowed to deduct specific financial expenses when calculating the tax base for PIS and COFINS. PIS and COFINS are recognized as components of profit (net of certain income and expenses); thus, in accordance with IAS 12, they are accounted for as income tax.

Tax Assets and Liabilities (excluding provisions for taxes) classified as "Current" are tax amounts to be recovered and tax amounts payable over the coming 12 months.

Deferred tax assets and liabilities of IR and CS comprise temporary differences, identified as the amounts expected to be paid or recovered arising from differences between the carrying amounts of assets and liabilities and their respective tax bases, as well as accumulated tax credits and losses. These amounts are measured at the tax rates expected to be applied in the period when the asset is realized or the liability is settled, and are reassessed at each balance sheet date.

Deferred tax assets are recognized only to the extent that it is probable that the consolidated entities will generate sufficient future taxable profits against which these deferred tax assets can be utilized. Furthermore, deferred tax assets must not arise from the initial recognition (except in the context of a business combination) of other assets and liabilities in transactions that do not impact either the actual profit or the accounting profit. Other deferred tax assets, such as tax credits and accumulated tax losses, are only recognized if it is considered probable that the consolidated entities will have sufficient future taxable profits against which they can be utilized.

**\*Values expressed in thousands, except when indicated**<br>

Income and expenses directly recognized in equity are accounted for as temporary differences.

The Bank's expectation for the realization of deferred tax assets is based on future results projections and underpinned by a technical study, as detailed in **note 23**.

**aa) Consolidated statement of cash flows**

The terms outlined below are employed in the Consolidated Statement of Cash Flows with the respective meanings:

• Cash flows: inflows and outflows of cash and cash equivalents, which are highly liquid financial investments subject to an insignificant risk of value changes and typically have a maturity of approximately three months or less from the original acquisition date.

• Operating activities: the principal activities that generate revenue for financial institutions and other activities that are not related to financing or investment activities.

• Investing activities: the acquisition and sale of long-term assets and other investments not included in cash and cash equivalents.

• Financing activities: activities that result in changes in the amount and composition of equity and liabilities that are not operating activities.

When preparing the consolidated statement of cash flows, highly liquid financial investments with insignificant risk of changes in their values were classified as "Cash and cash equivalents". The Bank classifies as cash and cash equivalents the balances recorded in the items "Cash and reserves at the Central Bank of Brazil" and "Loans and other amounts with credit institutions" in the consolidated balance sheet, except for resources for restricted use and long-term operations term.

Interest paid and received corresponds to Banco Santander's operating activities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Basis for consolidation** 

Highlighted below are both the direct and indirect subsidiaries, as well as investment funds included in the Consolidated Financial Statements of Banco Santander. Similar information regarding entities accounted for using the equity method by the Bank is provided in **note 11**.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Renault, the car manufacturer (an entity
not belonging to the Santander Conglomerate), sells its receivables to the Fund. This Fund exclusively buys receivables from Renault,
the car manufacturer. In turn, Banco RCI Brasil S.A. holds 100% of its shares.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Banco Santander was listed as a creditor
in certain overdue credit transactions that had real estate as collateral. The operation to recover these credits consisted of contributing
the real estate as collateral to the capital of the Real Estate Investment Fund and subsequently transferring the Fund's shares to Banco
Santander, through payment in kind for the aforementioned credit transactions.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Banco Santander, through its subsidiaries,
holds the risks and benefits of Santander Paraty and its exclusive fund Santander FI Hedge Strategies, resident in Ireland, and both are
fully consolidated in its Consolidated Financial Statements. Santander Paraty does not have its own equity position, and all records originate
from the financial position of Santander FI Hedge Strategies.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Fund controlled by Return Capital Gestão
de Ativos e Participações S.A.

Additionally, the entity Vert-11 Companhia Securitizadora de Créditos Financeiros was consolidated, as Banco Santander has full control over its assets.

**a)** **&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Incorporation of Toro Asset Management S.A. by Santander Investimentos Sociedade Prestadora de Serviços de Ativos Virtuais S.A.**

On December 31, 2025, Toro Asset Management S.A. ("Toro Asset") was fully merged, with its assets absorbed by its direct parent company, Santander Investimentos Sociedade Prestadora de Serviços de Ativos Virtuais S.A. ("Santander Investimentos"), in accordance with the conditions established in the Transaction Protocol and Justification. The implementation of the full merger of Toro Asset did not imply an increase in the share capital of Santander Investimentos, since all of the shares issued by Toro Asset were held by Santander Investimentos and, therefore, already reflected in an equity investment account.

**b)** **&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Partial spin-off of Return Capital Gestão de Ativos e Participações S.A. and incorporation of the spun-off portion by Banco Santander (Brasil) S.A.**

On November 28, 2025, the partial spin-off of Return Capital Gestão de Ativos e Participações S.A. ("Return") was approved, with the spun-off portion being incorporated by Banco Santander (Brasil) S.A. The operation aims to simplify the corporate structure, unify accounting processes, and reduce operational costs. The implementation of the incorporation of the spun-off portion of Return did not imply an increase in the share capital of Santander, since all of Return's issued shares are held by Santander Brasil and, therefore, already reflected in an investment account by equity method; on the other hand, Return's share capital was reduced by R$8,460,000, which corresponds to the spun-off portion.

**c)** **&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Merger of Santander Leasing S.A. Arrendamento Mercantil by Banco Santander (Brasil) S.A.**

On November 28, 2025, the merger of Santander Leasing S.A. Arrendamento Mercantil ("Santander Leasing") into Banco Santander (Brasil) S.A. was approved. The operation aims to simplify the corporate structure, unify accounting processes, and reduce operational costs, in accordance with the conditions established in the Protocol and Justification of the operation. The full merger of Santander Leasing did not imply an increase in the share capital of Santander Brasil, since all the shares issued by Santander Leasing were held by Santander Brasil and, therefore, already reflected in an investment account by equity method. The merger will only take effect after approval by the Central Bank of Brazil.

**8.** **Derivative financial instruments** 

The primary risk factors associated with the derivative instruments undertaken relate to exchange rates, interest rates, and equity income. In managing these and other market risk factors, the Bank employs practices that encompass the measurement and monitoring of the utilization of limits previously established by internal committees, the portfolios' value at risk, sensitivities to interest rate fluctuations, foreign exchange exposure, liquidity gaps, among other practices that enable the control and monitoring of risks, which could potentially impact Banco Santander's positions across the various markets in which it operates. Based on this management model, the Bank has been able to optimize the risk-reward ratio, even amidst conditions of significant volatility, through the use of operations involving derivative instruments.

The fair value of derivative financial instruments is determined using market price quotations when available. The fair value of swaps is calculated through discounted cash flow modeling techniques, reflecting appropriate risk factors. The fair value of forward and futures contracts is also determined based on market price quotations for exchange-traded derivatives or employing methodologies similar to those used for swaps. The fair value of options is calculated using mathematical models, such as the Black-Scholes model, implied volatilities, and the fair value of the corresponding asset. Current market prices are utilized to determine volatilities. For derivatives that do not have prices directly disclosed by exchanges, the fair value is ascertained through pricing models that leverage market information, inferred from the disclosed prices of more liquid assets. This process involves extracting interest rate curves and market volatilities from these prices, which are then used as input data for the models.

**a.5) Information on Credit Derivatives**

Banco Santander uses credit derivatives with the objectives of performing counterparty risk management and meeting its customers' demands, performing protection purchase and sale transactions through credit default swaps and total return swaps, primarily related to Brazilian sovereign risk securities.

**Total *Return Swaps* – TRS**

These are credit derivatives in which the return from the reference obligation is exchanged for a cash flow, and where upon the occurrence of a credit event, the protection buyer typically has the right to receive from the protection seller the equivalent of the difference between the updated value and the fair value of the benchmark obligation at the contract's settlement date.

***Credit Default Swaps* – CDS**

These are credit derivatives where, upon the occurrence of a credit event, the protection buyer is entitled to receive from the protection seller an amount equal to the difference between the face value of the CDS contract and the fair value (fair value) of the benchmark obligation at the settlement date of the contract. In exchange, the seller receives a fee for providing the protection.

During the period, there were no credit events associated with the precipitating factors specified in the contracts.

**a.6) Accounting Hedge**

There are three types of hedge accounting: Fair Value Hedge, Cash Flow Hedge and Foreing Currency Investments Hedge.

The derivatives used as hedging instruments are represented as follows:

**a.6.I) Fair Value Hedge** 

The Bank's fair value hedging strategy involves mitigating exposure to fair value fluctuations, specifically regarding interest receipts and payments on recognized assets and liabilities.

The fair value management methodology adopted by the Bank segregates transactions based on risk factors (e.g., BRL/USD exchange rate risk, fixed interest rate risk in BRL, USD exchange rate coupon risk, inflation risk, interest risk, etc.). The transactions generate exposures that are consolidated by risk factor and compared with pre-established internal thresholds.

To mitigate fluctuations in fair value associated with the receipt and payment of interest, the Bank employs interest rate swap contracts concerning fixed-rate assets and liabilities.

The Bank utilizes fair value hedge in the following manner:

**\*Values expressed in thousands, except when indicated**<br>

• Designates Foreign Currency Swaps + Coupon versus % CDI and Fixed BRL Interest Rate or contracts USD Futures (DOL, DDI/DI) as a derivative instrument in Hedge Accounting structures, with foreign currency loan operations as the hedged item.

• The Bank maintains an active loan portfolio originated in fixed-rate U.S. Dollars at Santander EFC, whose transactions are recorded in Euros. To manage this currency mismatch, the Bank designates a Foreign Currency Swap, exchanging Floating Euros for Fixed U.S. Dollars, as a hedge against market risk for the corresponding loans.

• The Bank is subject to a pre-fixed interest rate risk stemming from Government Securities (NTN-F and LTN) held within its Financial Assets portfolio, which are measured through Other Comprehensive Income. To manage this risk mismatch, the Bank enters into DI futures contracts on the exchange or engages in interest rate swaps, designating these as derivative instruments within a Hedge Accounting structure.

• The Bank is exposed to IPCA (broad consumer price index) risk stemming from debentures within its available-for-sale securities portfolio. To manage this exposure, the Bank enters into IPCA futures contracts ("DAP") on the exchange and designates them as derivative instruments within a Hedge Accounting structure.

Santander assesses effectiveness requirements through:

• Demonstration of the economic relationship between the hedged item and the hedging instrument through a qualitative test and, if not met, through quantitative tests that compare the market value of the hedged items, corresponding to the hedged risk, with the value of the hedging instruments. Additionally, a quantitative test of the variations in the market values of the hedging instrument and the hedged item is performed prospectively;

• Calculation of the hedge ratio, which corresponds to the ratio between the quantity of items effectively hedged by Santander and the quantity of hedging instruments effectively used;

• Assessment of the predominance of credit risk, carried out through the analysis of the credit risk exposure of the hedged items and the hedging instruments;

In fair value hedges, both gains and losses on hedging instruments and on the hedged items (attributable to the type of risk being hedged) are recognized directly in the consolidated statement of profit or loss.

**a.6.II) Cash Flow Hedge**

The Bank's cash flow hedging strategies consist of hedging against exposure to fluctuations in cash flows, interest payments, and currency exchange rates, which are attributable to changes in interest rates affecting recognized assets and liabilities, as well as exchange rate fluctuations impacting unrecognized assets and liabilities.

The Bank utilizes cash flow hedge in the following manner:

• The Bank engages in active swaps indexed to fixed US Dollars and liabilities in foreign currency, designating these as hedging instruments within a Cash Flow Hedge structure, where the hedged items are foreign currency loans negotiated with third parties via its offshore branches and Brazilian external debt securities measured at amortized cost.

• The Bank enters into Dollar Futures or DDI + DI Futures (Synthetic Dollar Futures) contracts and designates them as hedging instruments within a Cash Flow Hedge structure, where the hedged items are the Bank's portfolio of Dollar-denominated loans and Promissory Notes in the available-for-sale securities portfolio measured at Fair Value Through Other Comprehensive Income.

• The Bank maintains a portfolio of assets indexed to the Euro and traded in offshore branches. In the transaction, the value of the asset in Euros will be converted to Dollars at the exchange rate specified in the foreign exchange contract for the transaction. After this conversion, the principal amount of the transaction, now denominated in Dollars, will be adjusted by either a floating or a fixed rate. The assets will be hedged with a Cross-Currency Swap to transfer the Euro risk to LIBOR + Coupon.

Santander assesses effectiveness requirements through:

• Demonstration of the economic relationship between the hedged item and the hedging instrument through a qualitative test and, if not met, through quantitative tests that compare the market value of the hedged items, corresponding to the hedged risk, with the value of the hedging instruments. Additionally, a quantitative test of the variations in the market values of the hedging instrument and the hedged item is performed prospectively;

• Calculation of the hedge ratio, which corresponds to the ratio between the quantity of items effectively hedged by Santander and the quantity of hedging instruments effectively used;

• Assessment of the predominance of credit risk, carried out through the analysis of the credit risk exposure of the hedged items and the hedging instruments;

**\*Values expressed in thousands, except when indicated**<br>

In this hedging strategy, the effectiveness tests are conducted by comparing two proxies, one for the hedged item and another for the hedging instrument.

The hedged item proxy is a "conceptual" swap, where the passive leg mimics the part of the Stable Portion intended for protection, and the active pre-fixed leg mirrors the set of futures designated as the hedge, consistent with the market rates on the hedge designation day. The hedge instrument proxy is a "conceptual" swap, in which the active leg consists of the number of futures contracts designated as the hedge, and the passive pre-fixed leg represents the rate negotiated at the acquisition of these contracts. The proxy remains stable throughout the strategy as the contracts are held to maturity.

Any ineffectiveness is recognized in the income statement under the line item "Gains (losses) on financial assets and liabilities (net)."

In cash flow hedges, the effective portion of the change in the fair value of the hedging instrument is temporarily recognized in equity under the line item "Other Comprehensive Income - Cash Flow Hedges" (**note 25**) until the projected transactions take place. At that point, this portion is recognized in the consolidated statements of income, except if the projected transactions result in the recognition of non-financial assets or liabilities, in which case this portion will be included in the cost of the financial asset or liability. The ineffective portion of the change in the value of foreign exchange hedging derivatives is recognized directly in the consolidated statements of income. Furthermore, the ineffective portion of gains and losses on cash flow hedge instruments in a foreign operation is directly recognized in "Gains (losses) on financial assets and liabilities (net)" in the consolidated income statements.

&nbsp;&nbsp;&nbsp;&nbsp;**11.** **Investments in associates and joint ventures** 

<u>Jointly-controlled entities</u>

Banco Santander and its subsidiaries classify investments as joint control when they have shareholder agreements that require strategic, financial, and operational decisions to receive unanimous consent from all investors.

<u>Significant Influence</u>

Entities in which the Bank directly or indirectly holds significant influence are considered affiliated, characterized by the ability to participate in decisions regarding the financial and operational policies of the investee, without, however, exercising individual or joint control. Significant influence may arise from shareholding (presumed when it represents 20% or more of the affiliate's voting power) or from other factors, such as participation in governance bodies or relevant agreements between shareholders.

**\*Values expressed in thousands, except when indicated**<br>

Depreciation expenses were recorded under the "Depreciation and Amortization" line item in the income statement.

**b) Impairment losses**

For the period ended December 31, 2025, an impairment expense of R$20,001 (12/31/2024 – R$14,720) and loss due to obsolescence and discontinuation of fixed assets in the amount of R$268,868 (12/31/2024 - R$231,088)

**c) Commitment to purchase tangible assets**

As of December 31, 2025, the Bank had no contractual commitments for the acquisition of tangible assets.

&nbsp;&nbsp;&nbsp;&nbsp;**13.** **Intangible assets - Goodwill** 

Goodwill represents the surplus between the acquisition cost and the Bank's share in the net fair value of the acquired entity's assets, liabilities, and contingent liabilities. When this excess is negative (negative goodwill), it is immediately recognized in the income statement. In accordance with IAS 36, goodwill is tested annually for impairment or whenever there are indications of impairment to the cash-generating unit to which it has been allocated. Goodwill is recorded at its cost minus accumulated impairment losses. Impairment losses on goodwill are not reversed. Gains and losses from the disposal of an entity include the carrying amount of the goodwill associated with the entity sold.

The recorded goodwill is subject to impairment testing **(note 2.n.i).** The Bank's main goodwill, as shown in the table below, is due to the acquisition of Banco Real and has been allocated according to the operating segment (**note 44**).

For the year 2025, we present the assumptions used and results obtained in the recoverability tests of the Group's main goodwill.

A quantitative goodwill impairment test is conducted annually.

In the goodwill impairment test, conducted based on the December 2025 scenario, and where the discount and perpetuity growth rates are identified as the most sensitive assumptions for the calculation of the present value (value in use) of future discounted cash flows, it was determined that there is no evidence of impairment.

Based on the tests carried out, no loss of recoverable value of goodwill was identified on December 31, 2025 and 2024.

**\*Values expressed in thousands, except when indicated**<br>

**• Bandeprev - Bandepe Social Security**

Defined benefit plan sponsored by Banco Bandepe S.A. and Banco Santander, administered by Bandeprev. The plans are divided into Basic Plan, Special Plan 1 and Special Plan 2

with differences in eligibility, contributions and benefits by subgroups of participants. The plans have been closed to new members since 1999 for Banco Bandepe S.A. employees and to others since 2011.

**• Defined Contribution Plans**

**SantanderPrevi - Sociedade de Previdência Privada,** a private legal entity, non-profit, is a closed supplementary pension entity, constituted in accordance with current legal regulations, whose objective is the establishment and execution of pension benefit plans, complementary to the general social security system, in accordance with current legislation.

The SantanderPrevi Retirement Plan, although having Defined Contribution characteristics, is classified as a Variable Contribution plan due to 9 (nine) lifetime monthly annuities, with no new grants in this modality. The Plan has been closed to new members since July 2018, with contributions shared between sponsoring companies and plan participants. The amounts contributed by the sponsors for the fiscal year ending December 31, 2025 were R$61,717 at the Bank and R$67,619 in the Consolidated plan.

**SBPREV - Santander Brasil Open Pension Plan:** starting January 2, 2018, Santander offers an optional supplementary pension program for new employees and/or employees not enrolled in other plans within the Santander Brasil Conglomerate.

The program includes PGBL and VGBL plans, managed by Zurich Santander Brasil Seguros e Previdência S.A., open for new members. Contributions are shared between the sponsoring/endorsing companies.

The amounts appropriated by the sponsors in the fiscal year ended December 31, 2025 were R$2,630 in the Bank and R$3,246 in the Consolidated figures.

**• Former Banespa Employees**

The class action lawsuit filed by AFABESP (an association of retired and former employees of Banespa), seeking payment of a semi-annual bonus provided for in the old BANESPA bylaws, resulted in a final decision unfavorable to Banco Santander. As a result, each beneficiary of the decision may file an individual lawsuit to receive the amount due.

As the judgments adopted different positions for each case, a procedure called Incident of Resolution of Repetitive Demands (IRDR) was instituted before the Regional Labor Court (TRT) with the objective of establishing objective criteria regarding the theses defended by the Bank, mainly the prescriptive term and payment limitations until December 2006 (regarding the establishment of Plan V). On March 11, 2024, the IRDR incident was admitted for future judgment and the suspension of all lawsuits that are in the second instance (TRT) and filed in São Paulo (Capital) and other cities that are part of the jurisdiction of the TRT of São Paulo was determined.

Finally, due to the divergence in interpretation of the labor statute of limitations provided for in the Federal Constitution, an Action for Allegation of Non-Compliance with a Fundamental Precept (ADPF) was also filed, so that the Federal Supreme Court (STF) can resolve the issue and indicate the correct term to be used in the individual cases filed.

On June 27, 2024, a transaction was signed between Banco Santander, BANESPREV, AFABESP and legal advisors establishing criteria and conditions for the settlement of individual lawsuits. By August 23, 2024 (end of the adhesion period), approximately 90% of eligible beneficiaries had formalized their adhesions to said transaction, which were subsequently approved by court decision, and the respective individual lawsuits will be extinguished. Banco Santander registered an obligation related to the amounts effectively due for payment of the transaction. The amounts due for the installments settled to date, equivalent to R$2,369 million, were contributed by Banco Santander to the respective plans administered by Banesprev, responsible for administering the supplementary pension plans and for paying the transaction to the respective beneficiaries. The remaining installments, registered as obligations for employee benefit plans (note 18), will be contributed to Banesprev by May 2026, updated according to the criteria and the adjustment index for benefits provided for in the regulations of the plans to which each holder is linked.

The other individual processes, whose beneficiaries did not adhere to the aforementioned transaction, are pending a final decision regarding the disputed legal issues, which will be resolved when the IRDR and ADPF are judged.

**b) Medical and dental care plan**

**Cabesp - Caixa Beneficente dos Funcionários do Banco do Estado de São Paulo (Benefit Fund for Employees of the Bank of the State of São Paulo):** an entity dedicated to covering medical and dental expenses for employees hired before the privatization of Banespa in 2000, as defined in the entity's bylaws.

**ABN:** The health insurance plan is lifelong and a closed-end plan; it required a 10-year employment relationship with Banco Real and being 55 years of age. The retiree pays 70% of the monthly fee, and the bank subsidizes 30%. This rule was in effect until December 2002, after which the departing retiree pays 100% of the Monthly fee.

Both plans have co-payments and the inclusion of new dependents is not permitted.

**Bandeprev Medical Assistance:** a medical assistance plan granted to retirees from the Bank of the State of Pernambuco; it is a lifetime benefit. Banco Santander subsidizes 50% of the plan's cost for those who retired before November 27, 1998. For those who retired after this date, the subsidy is 30%.

The plan will be under the same rules in effect at the time of termination, and the Partner must pay the monthly fee via bank slip. Active dependents at the time of termination remain on the health plan, according to the current policy, and the inclusion of new dependents is not permitted.

Additionally, retired employees are guaranteed the right to remain beneficiaries of Banco Santander's health plan, provided they meet certain legal requirements and assume full payment of their respective contributions, under the same coverage conditions they enjoyed during their employment contracts. Banco Santander's obligations to retirees are assessed using actuarial calculations based on the present value of current costs.

**III. Actuarial Techniques**

• **Valuation method** 

Projected unit credit method, which views each year of service resulting in an additional unit of benefit entitlement and measures each unit separately.

**b.1) Provisions for contingent payments**

As stated in **note 1.iv**, IFRS 9 mandates the recognition of a provision for expected loan losses on financial guarantee contracts that have not yet been honored. This provision expense, reflecting the credit risk, must be measured and recognized when such guarantees are honored and the guaranteed customer fails to meet their contractual obligations. Changes in these provisions during the fiscal years of 2025, 2024 and 2023 are detailed below.

**c) Provisions for Tax and Social Security, Labor and Civil Matters**

Banco Santander and its subsidiaries are involved in judicial and administrative proceedings related to tax, social security, labor, and civil matters, arising from their regular business operations.

Provisions have been established based on the nature, complexity, and historical context of the legal proceedings, as well as on the assessment of loss in the companies' proceedings, informed by the opinions of both internal and external legal advisors. It is Banco Santander's policy to fully provision the value at risk for proceedings deemed to have a probable loss.

Management understands that the provisions made are sufficient to meet legal obligations and potential losses arising from judicial and administrative proceedings as follows:

**c.1) Judicial and Administrative Proceedings Pertaining to Tax and Social Security Matters**

**Main judicial and administrative proceedings with probable loss risk**

Banco Santander and its subsidiaries are involved in judicial and administrative proceedings related to tax and social security disputes, which are classified based on the opinion of legal advisors as having a probable loss risk.

**Provisional Contribution on Financial Transactions (CPMF) in Client Operations**) In May 2003, the Brazilian Federal Revenue Service issued a tax assessment notice against Santander Distribuidora de Títulos e Valores Mobiliários Ltda. (Santander DTVM) and another notice against Banco Santander (Brasil) S.A. The purpose of the proceedings was the collection of CPMF on transactions carried out by Santander DTVM in the management of its customers' funds and clearing services provided by the Bank to Santander DTVM, which occurred during the years 2000, 2001 and 2002. The administrative proceeding ended unfavorably for both Companies. On July 3, 2015, Banco and Santander Brasil Tecnologia S.A. (current name of Produban Serviços de Informática S.A. and Santander DTVM) filed a lawsuit seeking to cancel both tax debts. Said lawsuit resulted in an unfounded sentence and ruling, which led to the filing of a Special Appeal to the STJ and an Extraordinary Appeal to the STF, which are awaiting judgment. The cases related to the CPMF (Provisional Contribution on Financial Transactions) in Client Operations were subject to adherence to the Comprehensive Transaction Program (PTI), instituted by the Ministry of Finance. In December 2025, the amounts paid, totaling R$1,067 million established in the transaction, were fully provisioned.

**National Institute of Social Security (INSS)** - R$167 milion in Consolidated (12/31/2024 - R$142 milion in Consolidated) Banco Santander and the controlled companies discuss administratively and judicially the collection of the contribution of social security and education salary on various funds that, according to the assessment of legal advisors, do not have a salary nature.

**Service Tax (ISS) - Financial Institutions** – R$335 milion in Consolidated (12/31/2024 - R$366 milion in Consolidated): Banco Santander and the controlled companies are administratively and judicially discussing the requirement, for several municipalities, for the payment of ISS on various revenues arising from operations that are not usually classified as provision of services. Furthermore, other actions involving ISS, classified as possible risk of loss, are described in **note 22.e.**

**c.2) Judicial and Administrative Proceedings Pertaining to Labor Matters**

These are legal actions initiated by Labor Unions, Associations, the Labor Public Prosecutor's Office, and former employees, claiming labor rights they believe are due, particularly regarding the payment of "overtime" and other labor rights, including proceedings related to retirement benefits.

**\*Values expressed in thousands, except when indicated**<br>

For claims regarded as routine and alike in nature, provisions are recorded based on the historical average of settled cases. Claims that do not meet this criterion are provisioned based on an individual assessment, with provisions established according to the probable risk of loss, in compliance with the law and jurisprudence, as determined by the loss assessment conducted by legal advisors.

**c.3) Judicial and Administrative Proceedings Pertaining to Civil Matters**

These provisions typically arise from: (i) claims requesting a review of contractual terms and conditions or monetary adjustment requests, including alleged impacts from the implementation of various government economic plans, (ii) claims related to financing contracts, (iii) enforcement actions, and (iv) claims for compensation for losses and damages. For civil claims deemed routine and alike in nature, provisions are recorded based on the historical average of settled cases. Claims that do not meet this criterion are provisioned based on an individual assessment, with provisions established according to the probable risk of loss, in compliance with the law and jurisprudence, as determined by the loss assessment conducted by legal advisors.

The main proceedings classified as probable loss risk are detailed below:

**Compensatory Actions** - These relate to compensation for material and/or moral damages arising from consumer relationships, primarily involving issues related to credit cards, consumer loans, current accounts, collections, loans, and other matters. For claims concerning causes deemed alike and routine for the business, within the normal course of the Bank's operations, provisions are established based on the historical average of settled cases. Claims that do not meet this criterion are provisioned based on an individual assessment, with provisions set according to the probable risk of loss, in compliance with the law and jurisprudence, as determined by the loss assessment conducted by legal advisors.

**Economic Plans** - These relate to judicial proceedings that claim alleged inflationary adjustments arising from Economic Plans (Bresser, Verão, Collor I and II), on the basis that such plans infringed upon vested rights associated with the application of purportedly owed inflationary indices to Savings Accounts, Judicial Deposits, and Time Deposits ("CDBs"). The provisions for these lawsuits are based on the individualized assessment of loss conducted by legal advisors.

Banco Santander is also a party to public civil actions related to the same subject matter, initiated by consumer protection entities, the Public Prosecutor's Office, or Public Defenders. Provisions are recognized only for cases with a probable loss risk, based on individual enforcement requests. The issue is currently under review by the STF. There is existing jurisprudence in the STF that is favorable to banks concerning economic phenomena similar to that of savings accounts, such as in the case of inflation adjustments to time deposits ("CDBs") and adjustments applied to contracts ("tablita").

However, the jurisprudence of the STF regarding the constitutionality of the regulations that amended Brazil's monetary standard has not yet been established. On April 14, 2010, the Superior Court of Justice ("STJ") ruled that the deadline for initiating public civil actions related to the inflation adjustments is 5 years from the date of the plans, but this ruling has not yet become final and conclusive. Accordingly, with this decision, a significant number of the claims, as filed after the 5 years deadline, are expected to be declared unfounded, thereby reducing the amounts involved. The STJ also ruled that the deadline for individual savers to register for Public Civil Actions is 5 years, counted from the date of the final judgment of the respective case. Banco Santander is confident in the success of the positions it has advocated before these courts, due to their substance and rationale.

Towards the end of 2017, the Attorney General's Office ("AGU"), the Brazilian Central Bank ("Bacen"), the Consumer Defense Institute ("Idec"), the Brazilian Savers Front ("Febrapo"), and the Brazilian Federation of Banks ("Febraban") entered into an agreement with the objective of resolving the legal disputes related to the Economic Plans.

The discussions were centered on determining the amount to be paid to each claimant, based on the balance in the savings account as of the plan's date. The total amount of the payments will depend on the number of participants, as well as the number of savers who have successfully demonstrated in court the existence of the account and the balance on the anniversary date of the index adjustment. The settlement agreement negotiated between the parties was ratified by the STF.

In a ruling by the STF, a nationwide suspension of all legal proceedings concerning the issue was ordered for the duration of the agreement, except for cases where judgments are being definitively enforced.

On March 11, 2020, the agreement was extended through an addendum, incorporating lawsuits exclusively pertaining to the discussion of the Collor Plan I. This extension is for a term of 5 years, and the ratification of the addendum's terms took place on June 3, 2020.

In May 2025, the Argument of Non-Compliance with Fundamental Precept (ADPF) number 165 was judged, recognizing the constitutionality of the Bresser, Verão, Collor I and II plans and guaranteeing savers the receipt of the amounts established in the collective agreement and setting a deadline of 24 months for new savers to join.

Management believes that the provisions made are adequate to cover the risks associated with the economic plans, in light of the ratified agreement.

**c.4) Contingent Liabilities in Tax, Social Security, Labor, and Civil Matters Classified as Possible Loss Risk**

These are judicial and administrative proceedings related to tax, social security, labor, and civil matters, classified, based on the opinion of legal advisors, as carrying a risk of possible loss, therefore, not provisioned.

Tax lawsuits with a possible loss classification totaled R$37,518 milion in the Consolidated (12/31/2024 - R$35,834 milion), with the main lawsuits being as follows:

**PIS and COFINS**- Lawsuits filed by Banco Santander (Brasil) S.A. and other entities of the Group to prevent the application of Law No. 9,718/98, which changes the calculation basis of the Social Integration Program (PIS) and the Contribution for Social Security Financing (COFINS), extending it to all revenues of the entities, and not only to revenues arising from the provision of services. Regarding the Banco Santander (Brasil) S.A. case, in 2015 the Brazilian Supreme Court (STF) admitted the extraordinary appeal filed by the Federal Government regarding PIS and denied the extraordinary appeal filed by the Federal Public Prosecutor's Office regarding the contribution to COFINS, confirming the decision of the Federal Regional Court in favor of Banco Santander (Brasil) S.A. in August 2007. The STF decided, by means of General Repercussion, Theme 372 and partially accepted the Federal Government's appeal, establishing the thesis that PIS/COFINS is levied on operating revenues arising from the typical activities of financial institutions. With the publication of the judgment, the Bank filed a new appeal regarding PIS, which is awaiting analysis. Based on the assessment of legal advisors, the risk prognosis was classified as a possible loss, with an appeal not being probable. As of December 31, 2025, the amount involved is R$2,349 milion. For the other legal actions, the respective PIS and COFINS obligations were established.

**INSS on Profit Sharing or Results (PLR)** - The Bank and its subsidiaries are subject to legal and administrative proceedings arising from questions from tax authorities regarding the collection of social security contributions on payments made as profit sharing. On December 31, 2025, the amount was approximately R$11,090 milion.

**Service Tax (ISS) - Financial institutions** - Banco Santander and its subsidiaries are contesting both administratively and judicially the imposition by several municipalities of the ISS on various income derived from operations not typically recognized as service provision. As of December 31, 2025, the value was approximately R$3,778 milion .

**Non-Ratified Tax Offsetting** - The Bank and its subsidiaries are engaged in both administrative and legal disputes with the Federal Revenue Service over the non-ratification of tax offsets involving credits from overpayments or undue payments. As of December 31, 2025, the total amount was approximately R$7,068 milion.

**Losses in Credit Operations** -The Bank and its subsidiaries contested the tax assessments issued by the Brazilian Federal Revenue Service, alleging the undue deduction of losses on credit transactions from the IRPJ and CSLL calculation bases for allegedly not meeting the requirements of the applicable laws. On December 31, 2025, the amount was approximately R$1,153 milion.

**Use of CSLL Tax Loss and Negative Base** - Notices of infraction issued by the Brazilian Federal Revenue for the fiscal years 2009 and 2019, concerning alleged improper offsetting of tax losses and negative CSLL base, following tax assessments from previous periods. A decision in the administrative court is pending. As of December 31, 2025, the value was approximately R$2,729 milion .

**Amortization of Goodwill from Banco Sudameris Acquisition** - The tax authorities issued notices of violation to demand payment of IRPJ and CSLL, including late payment charges, related to the tax deduction of the amortization of the goodwill paid in the acquisition of Banco Sudameris, for the base period from 2007 to 2012. Banco Santander presented the respective administrative defenses. The first period assessed is awaiting analysis of an appeal at CARF. Regarding the period from 2009 to 2012, a lawsuit was filed to discuss the IRPJ portion, due to the unfavorable conclusion in the administrative process. For the CSLL portion of this same period, we request the withdrawal of the Special Appeal filed, aiming to take advantage of the benefits established by Law No. 14,689/2023 (quality vote). A lawsuit will be filed for the remaining portion. On December 31, 2025, the amount was approximately R$836 milion .

**IRPJ and CSLL Capital Gains** - The Brazilian Federal Revenue Service issued a tax assessment notice against Santander Seguros (legal successor of ABN AMRO Brasil Dois Participações S.A. (AAB Dois Par) charging income tax and social contribution related to the fiscal year 2005. The Brazilian Federal Revenue Service claims that the capital gain on the sale of shares of Real Seguros S.A. and Real Vida e Previdência S.A. by AAB Dois Par should be taxed at a rate of 34.0% instead of 15.0%. The assessment was administratively challenged based on the understanding that the tax treatment adopted in the transaction was in accordance with the current tax legislation and the capital gain was duly taxed. The administrative proceeding ended unfavorably to the Company. In July 2020, the Company filed a lawsuit seeking to cancel the debt. The lawsuit is awaiting judgment. Banco Santander is responsible for any adverse outcome in this proceeding as the former controlling shareholder of Zurich Santander Brasil Seguros e Previdência S.A. On December 31, 2025, the value was approximately R$603 milion .

**IRRF – Overseas Remittance** - The Company filed a lawsuit seeking to eliminate the taxation of Income Tax Withheld at Source – IRRF, on payments derived from the provision of technology services by companies headquartered abroad, due to the existence of International Treaties signed between Brazil-Chile; Brazil-Mexico and Brazil-Spain, thus avoiding double taxation. A favorable judgment was handed down and the National Treasury appealed to the Regional Federal Court of the 3rd Region, where it awaits judgment. On December 31, 2025, the amount was approximately R$1,524 milion.

Labor and civil lawsuits classified as having a potential loss totaled R$1,493 million and R$2,226 million, respectively, in the consolidated figures.

(1) PIS and COFINS are considered as components of the profit base (net base of certain income and expenses); therefore, in accordance with
IAS 12, they are recorded as income taxes.

(2) It mainly includes the tax effect on income from updates to judicial deposits and other income and expenses that are permanent differences.

(3) In the Consolidated Financial Statements, we account for the difference in CSLL (Social Contribution on Net Profit) tax rates of 9% (non-financial
companies), 15% (financial companies), and 20% (banks).

**Foreign Exchange Hedge of the Grand Cayman and Luxembourg Branches**

Banco Santander operates branches in the Cayman Islands and Luxembourg, which are primarily used for raising funds in international capital and financial markets, providing the Bank with credit lines that are extended to its clients for trade financing and working capital.

To hedge against exchange rate fluctuations, the Bank uses derivatives and funding. According to Brazilian tax rules, gains or losses resulting from the impact of the Real's appreciation or depreciation on foreign investments are taxable or deductible for income tax/social contribution purposes, while gains or losses from derivatives used as hedging are also taxable or deductible. The purpose of these derivatives is to protect net income after taxes.

&nbsp;&nbsp;&nbsp;&nbsp;**29.** **Fair value of financial assets and liabilities** 

According to IFRS 13, the measurement of fair value using a fair value hierarchy that reflects the model used in the measurement process must comply with the following hierarchical levels:

**Level 1:** Determined based on unadjusted public price quotations in active markets for identical assets and liabilities, including public debt securities, equities, and listed derivatives.

**Level 2:** Represents derivatives of data other than the quoted prices included in Level 1, which are observable for the asset or liability, either directly (such as prices) or indirectly (derived from prices).

**Level 3:** Derived from valuation techniques that incorporate data for assets or liabilities not based on observable market variables (non-observable data).

**Financial Assets and Liabilities Measured at Fair Value through Profit or Loss or through Other Comprehensive Income**

**Level 1:** Securities and financial assets characterized by high liquidity and observable prices in an active market are classified within level 1. This level includes most Brazilian Government Securities (notably LTN, LFT, NTN-B, and NTN-F), stocks listed on the stock exchange, and other securities traded in the active market.

**Level 2:** When price quotes are not observable, Management, utilizing its own internal models, makes its best estimate of the price that would be established by the market. These models rely on data based on observable market parameters as a key reference. The most reliable evidence of the fair value of a financial instrument at initial recognition is the transaction price, unless the fair value can be derived from other market transactions involving the same or similar instruments, or can be determined using a valuation technique where the variables used include only observable market data, particularly interest rates. These securities are classified at level X of the fair value hierarchy and primarily consist of Government Securities (NTN-A), repurchase agreements, cancellable LCI, and are in a market that is less liquid than those classified at level 1.

**Level 3:** In cases where information is not based on observable market data, Banco Santander employs internally developed models to accurately measure the fair value of these instruments. Instruments with low liquidity are primarily classified at level 3.

**Derivatives**

**Level 1:** Derivatives traded on stock exchanges are classified within level 1 of the hierarchy.

**\*Values expressed in thousands, except when indicated**<br>

**Level 2:** Derivatives traded over-the-counter, in the valuation of financial instruments (mainly swaps and options), observable market data such as exchange rates, interest rates, volatility, correlations between indices, and market liquidity are typically utilized.

In pricing the referenced financial instruments, the Black-Scholes model methodology (exchange rate options, interest rate index options, caps, and floors) and the present value method (discounting future values based on market curves) are employed.

**Level 3:** Non-exchange traded derivatives, for which there is no observable information in an active market, have been classified as level 3, encompassing exotic derivatives.

 **Fair Value Changes Linked to Credit Risk**

Fair value changes attributable to credit risk are determined based on fluctuations in credit default swap prices relative to similar obligations of the same debtor, when such prices are observable, as credit default swaps more accurately reflect the market's assessment of credit risks for a specific financial asset. When these prices are not observable, the fair value changes attributable to credit risk are calculated as the total of fair value changes not attributable to shifts in the benchmark interest rate or other observable market rates. In the absence of specific observable data, this approach provides a reasonable approximation of the changes attributable to credit risk, estimating margin changes over the benchmark value that the market may demand for the financial asset.

**Financial assets and liabilities not measured at fair value**

The Bank's financial assets are measured at fair value in the consolidated balance sheet, except for financial assets measured at amortized cost.

Similarly, the Bank's financial liabilities, excluding those held for trading and those measured at fair value, are measured at amortized cost in the consolidated balance sheet.

The methodologies and assumptions applied in estimating fair value are outlined below:

**Loans and other receivables from credit institutions and customers** - The fair value is estimated for groups of similar credit transactions. The fair value of loans is determined by discounting future cash flows using the interest rates of new contracts. In other words, the future cash flow of the current loan portfolio is projected based on contractual rates, and then, spreads derived from new loans are incorporated into the risk-free interest rate curve to calculate the fair value of the loan portfolio. Regarding behavioral assumptions, it is important to underscore that the prepayment rate is applied to the loan portfolio, thereby enabling a more realistic projection of future cash flows.

**Deposits from credit institutions and customers** - The fair value of the deposits was calculated by discounting the difference between the cash flows under contractual conditions and the current market rates for instruments with similar maturities. The fair value of variable-rate time deposits was considered to be close to their carrying amount.

**Liabilities arising from securities** - The fair values of these items were estimated by calculating the discounted cash flows, using the market interest rates for liabilities with similar terms and maturities.

**Debt Instruments Eligible as Capital** – these refer to the transaction fully executed with a related party, within the context of the Capital Optimization Plan, whose carrying amount is similar to the fair value.

The valuation techniques employed for estimating each level are detailed in **note 2.e**.

Management reviewed the criteria for classifying the fair value level of assets and liabilities measured at amortized cost, which are presented exclusively for disclosure purposes, and concluded that they are more appropriately classified as level 3, given the observable market data.

&nbsp;&nbsp;&nbsp;&nbsp;**30.** **Operational Ratios** 

The Brazilian Central Bank requires financial institutions to maintain a Regulatory Capital (RC), Tier 1 Capital, and Common Equity Tier 1 Capital (CET1) that are compatible with the risks inherent in their activities, exceeding the minimum Required Regulatory Capital, represented by aggregating the credit risk, market risk, and operational risk components.

As established in CMN Resolution No. 4,958/2021, the Regulatory Capital requirement is set at 11.50%, comprising 8.00% of Minimum Regulatory Capital, 2.50% of Capital Conservation Buffer, and 1.00% of Systemic Risk Buffer. The Tier 1 Capital Ratio stands at 9.50%, and the Minimum Common Equity Tier 1 Capital is 8.00%. Continuing with the implementation of the rules set forth by CMN Resolution No. 4,955/2021, the calculation of capital adequacy ratios is conducted on a consolidated basis, utilizing data from the Prudential Conglomerate, as established by CMN Resolution No. 4,950/2021, demonstrated below:

**Global ILP (Long Term Incentive) Plans)**

Currently, we have active global plans launched between 2019 and 2024, targeting global stocks and options, whose design includes:

&nbsp;&nbsp;&nbsp;&nbsp;• Clear definition of performance metrics
(financial and non-financial);

&nbsp;&nbsp;&nbsp;&nbsp;• Multi-year deferral, ensuring a focus on
sustainable results;

&nbsp;&nbsp;&nbsp;&nbsp;• Settlement in assets or financial equivalents,
in accordance with malus and clawback rules.

This structure aligns with international best practices in compensation governance, reinforcing transparency and capital discipline.

**\*Values expressed in thousands, except when indicated**<br>

**Pricing Model**

The measurement of the plans is based on the Local Volatility (Dupire) model, adjusted to incorporate uncertainties in dividends, offering greater accuracy in the fair value estimate. The main parameters considered include:

&nbsp;&nbsp;&nbsp;&nbsp;• Weighted average share price;

&nbsp;&nbsp;&nbsp;&nbsp;• Exercise price;

&nbsp;&nbsp;&nbsp;&nbsp;• Implied and expected volatility;

&nbsp;&nbsp;&nbsp;&nbsp;• Risk-free interest rate;

&nbsp;&nbsp;&nbsp;&nbsp;• Dividend projection.

The options have expiration dates up to 2033, and the exercise price corresponds to the market value on the exercise date, conditional upon achieving the established targets.

**Local ILP Plans (Long-Term Incentive)**

Local long-term incentive plans may be granted in accordance with the strategy of new companies in the group or specific businesses, generally with a vesting period of 3 (three) years.

Each plan has a specific contract, and its calculation and payment must be approved by the established governance body, observing local and global regulatory resolutions.

The reference value for each participant will be converted into SANB11 shares, typically based on the price of the last 50 trading sessions of the month immediately preceding the plan payment.

At the end of the vesting period, payment, whether for the resulting shares in the case of local plans or the equivalent value of the shares/options in the case of global plans, is made with a restriction of 1 (one) year, and this payment is also subject to the application of Malus/Clawback clauses, which may reduce or cancel the shares to be delivered in cases of non-compliance with internal rules and exposure to excessive risks, or in cases of material failure to comply with the requirements for financial reporting, in accordance with Section 10D of the Securities Exchange Act (SEC), applicable to companies with shares listed on the NYSE.

**b.2) Stock-Based Variable Compensation**

&nbsp;&nbsp;&nbsp;&nbsp;**43.** **Other disclosures** 

**a) Guarantees and commitments**

The Bank offers a range of guarantees to help its clients improve their credit standing and enable them to compete effectively. The table below details all the guarantees as of December 31, 2025 and 2024.

As required, the "Maximum potential value of future payments" represents the notional amounts that could be regarded as a loss in the event of a total default by the guaranteed parties, without taking into account possible recoveries from guarantees held or pledged, or recoveries on appeal. There is no correlation between these values and the probable losses on these guarantees. In fact, the "Maximum potential value of future payments" significantly exceeds the inherent losses.

(1) Includes approved and unutilized limits for overdrafts, credit cards, and other similar facilities.

The Bank provides its clients with financial guarantees in commitments with third parties. The Bank retains the right to seek reimbursement from clients for any amounts it is required to pay under these guarantees. Additionally, cash or other forms of high liquidity collateral may be held against these commitments. These contracts are subject to the same credit assessment process as that applied to loans.

The Bank expects that these guarantees will expire without the need for any cash advances. Therefore, in the normal course of operations, the Bank anticipates that these transactions will have virtually no impact on its liquidity.

Performance guarantees are issued to secure clients' commitments, such as contractually specified investments, and to provide specified products, basic goods, or maintenance or warranty services to third parties, ensuring project completion in accordance with contractual terms, among other obligations. Included within standby letters of credit are guarantees for loan repayment, credit lines, promissory notes, and commercial acceptances. The Bank invariably requires collateral to issue this type of financial guarantee. In documentary credits, the Bank acts as a payment intermediary between commercial entities across different countries (import/export operations). In these transactions, the parties involved handle documents rather than the actual goods these documents represent. Typically, the basic goods traded serve as collateral for the transaction, and the Bank may extend certain credit lines. Commitments for loans redeemable by third parties primarily encompass most credit card lines and commercial commitments. Credit card lines may be unilaterally terminated by the issuer. Commercial commitments are generally one-year lines, contingent upon the client providing requisite information.

**\*Values expressed in thousands, except when indicated**<br>

The risk criteria for issuing all types of guarantees, standby letters of credit, documentary credits, and all signature risks are generally the same as those used for other credit risk products and, therefore, are subject to the same admission and monitoring standards. Guarantees provided on behalf of clients undergo the same credit quality review process as any other credit risk product. Regularly, at least once a year, the solvency of clients is assessed, as well as the likelihood of these guarantees being executed. Should there be any doubt regarding a client's solvency, provisions are recognized in net profit for the amount of inherent losses, even if no legal proceedings have been initiated against the Bank.

The recognition of provisions for impairment losses related to guarantees and other sureties (**note 9.c**) is recorded under the line item Impairment losses on financial assets (net) in the consolidated statement of income, and the methodology for its calculation is detailed in **note 2.i**.

Furthermore, the liability recognized as deferred income for the premium received for providing these guarantees is being amortized over the life of the related guarantees and totals R$253,677 (2024 - R$300,711 and 2023 - R$282,613).

**b) Managed funds not recognized on the balance sheet**

Banco Santander manages funds in which it does not hold a significant stake, does not act as a "principal," and has no equity interest. Based on the contractual relationship that governs the management of these funds, other equity holders are exposed to, or have rights to variable returns and are able to influence these returns through their decision-making authority. Additionally, the Bank act as manager of these funds by analyzing the remuneration regime, which is proportional to the services rendered. Therefore, there is no indication that the fund is "principal" **(note 2.w).**

Following are the funds managed by Banco Santander not recognized on its balance sheet:

Additionally, Banco Santander holds indefinite-term contracts, amounting to R$488 (2024 - R$431), corresponding to the monthly lease payments for contracts of this nature. Lease payments, recognized as expenses in the fiscal year of 2025, totaled R$194,402 (2024 - R$256,371).

Lease agreements will be adjusted annually in accordance with prevailing legislation, where the maximum adjustment is based on the fluctuation of the General Market Price Index ("IGPM"). The lessee is granted the right to unilaterally terminate these agreements at any time, pursuant to contractual clauses and current legislation.

**g) Contingent assets**

As of December 31, 2025 and 2024, contingent assets were not recognized in the accounting records.

&nbsp;&nbsp;&nbsp;&nbsp;**44.** **Business segment reporting** 

In accordance with IFRS 8, an operating segment is defined as a component of an entity:

&nbsp;&nbsp;&nbsp;&nbsp;(a) That engages in activities from which it
can generate income and incur expenses (including income and expenses arising from transactions with other components of the same entity);

&nbsp;&nbsp;&nbsp;&nbsp;(b) Whose operational results are regularly
reviewed by the entity's chief decision-maker responsible for operational decisions regarding the allocation of resources to the
segment and assessment of its performance; and

&nbsp;&nbsp;&nbsp;&nbsp;(c) For which separate financial information
is available.

Based on these guidelines, the Bank has identified the following reportable operating segments:

• Commercial Bank

• Global Wholesale Bank (SCIB)

The Bank operates across two segments: the Commercial Segment, catering to both individual and corporate clients (excluding global corporate clients, who are served in the Global Wholesale Banking Segment), and the Global Wholesale Banking Segment, which encompasses Investment Banking and Markets operations, including the Treasury and Equity Business Departments.

The Bank operates both in Brazil and internationally through its branches in Cayman and Luxembourg, as well as its subsidiary in Spain, serving Brazilian clients. Accordingly, it does not present geographical segmentation.

&nbsp;&nbsp;&nbsp;&nbsp;**46.** **Risk management** 

Risk management at Banco Santander is based on the following principles:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Risk
function independence from the commercial department.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Senior
Management involvement in decision-making.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Consensus
between the Risk and Commercial departments on lending decisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Collective
decisions, involving the branch network, aimed at fostering diversity of opinions and preventing the assignment of individual decisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. Use
of statistical forecasting tools for default prediction, including internal ratings, credit scoring, behavior scoring, RORAC (Risk-Adjusted
Return on Capital), VaR (Value at Risk), economic capital, and scenario analysis, among other methods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;M. Maintaining
a medium-low risk profile and low volatility through:

&nbsp;&nbsp;&nbsp;&nbsp;• Portfolio diversification, by limiting concentrations
in clients, groups, sectors, products, or geographies; reducing the complexity of market operations; analyzing the social and environmental
risks of businesses and projects financed by the Bank; and continuous monitoring to prevent portfolio deterioration.

&nbsp;&nbsp;&nbsp;&nbsp;• Establishment of policies and procedures
that constitute the Normative Risk Model, governing risk-related activities and processes in compliance with directives from the Board
of Directors, Brazilian Central Bank regulations, as well as international best practices, aiming to safeguard capital and ensure the
profitability of business operations.

At Santander Brasil, the risk control and management process was determined based on the Framework set forth at the corporate level, outlined according to the following phases:

&nbsp;&nbsp;&nbsp;&nbsp;I. Adaptation of risk management structures
and policies in alignment with Banco Santander's risk management principles.

The Corporate Risk Management Framework, approved by Senior Management (Risks), is designed to establish the principles and standards for risk management and control at Banco Santander. It is based on corporate organizational models and complies with the requisite regulatory standards for credit management.

The organizational model consists of the management map, which delineates the responsibilities of each area by risk type, the risk governance function, and the regulatory framework itself.

&nbsp;&nbsp;&nbsp;&nbsp;II. Risk identification through continuous review
and monitoring of exposures, assessment of new products and business ventures, and specific analysis of unique transactions.

&nbsp;&nbsp;&nbsp;&nbsp;III. Risk measurement using periodically tested
methods and models.

&nbsp;&nbsp;&nbsp;&nbsp;IV. Preparation and distribution of a comprehensive
set of reports, which undergo daily review by the Executive Board of Banco Santander.

&nbsp;&nbsp;&nbsp;&nbsp;V. Implementation of a risk control system
that assesses, on a daily basis, the extent to which the Bank's risk profile conforms to approved policies and established limits. The
most significant tools and techniques (previously mentioned), currently employed by Banco Santander, are at various stages of maturity
regarding their implementation and application within the Bank. For the wholesale segment, these techniques are aligned with corporate-level
development. For other segments, models based on internal classifications and score systems, VaR analysis, market risk scenario analysis,
and stress testing have already been integrated into the risk management routine, while the integration of expected loss, economic capital,
and RORAC into risk management is underway.

&nbsp;&nbsp;&nbsp;&nbsp;VI. Models based on internal classifications
and score systems, which, by assessing the various qualitative and quantitative risk components for each client and transaction, enable
the estimation of the probability of default initially, and subsequently, the loss based on LGD estimates.

&nbsp;&nbsp;&nbsp;&nbsp;VII. Economic capital, as a consistent measure
of assumed risk and a basis for evaluating management performance.

VIII.RORAC, utilized both as a pricing tool in wholesale operations, particularly within global relationship companies (employing a bottom-up approach), and in the analysis of portfolios and business units (using a top-down approach).

&nbsp;&nbsp;&nbsp;&nbsp;IX. VaR, utilized to control and set market
risk limits for the treasury's various portfolios.

&nbsp;&nbsp;&nbsp;&nbsp;X. Scenario analysis and stress testing to
complement market and credit risk assessments in order to evaluate the impact of alternative scenarios, including on provisions and capital.

**a) Corporate Governance of the Risk Function**

The structure of Banco Santander's Risk Committees is defined in line with a prudent risk management standard, always in compliance with the local regulatory and normative environment. Its primary responsibilities are the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Integrate
and adapt the Bank's risk culture to the local context, in addition to the risk management strategy, tolerance level, and risk appetite,
previously approved by the Executive Committee and the Board of Directors, all in alignment with the corporate standards of Banco Santander
Spain;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Assess
and approve proposals, operations, and limits, whether related to credit or market, for clients and portfolios;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Conduct
periodic monitoring of all inherent business risks, ensuring that the risk profile is aligned with the established risk appetite;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Authorize
the use of management tools, local risk models, and understand the results of their internal validation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. Remain
informed, assess, and comply with any observations and recommendations that may periodically be issued by supervisory authorities in
the execution of their duties;

The credit risk management structure is composed of directorates that operate from the perspective of managing retail and wholesale portfolios. One specific area is tasked with consolidating portfolio information and its respective risks, providing management with an integrated and holistic view of risks, as is done in the Santander Group. In addition, there is another specific structure responsible for responding to regulators, supervisors, and internal and external auditors.

The consolidated view of risks is composed of two core elements:

&nbsp;&nbsp;&nbsp;&nbsp;• ERM - Enterprise Risk Management: comprised
of a set of functions, transversal to all risks, necessary for adequate management. This structure includes the areas of Strategic Risk
and Supervision, ESCC Risk and Governance, Costs and Risk Performance.

&nbsp;&nbsp;&nbsp;&nbsp;• Risk Adequacy and Infrastructure: comprised
of a set of functions linked to a holistic view of credit risk and models. This structure includes the areas of Credit Risk Control, Regulatory
Models, Credit Risk Information, Stress Testing, and Capital Risk.

**b) Credit Risk**

**b.1) Introduction to credit risk management**

Credit Risk Management supports the formulation of strategies in alignment with risk appetite, while also setting limits that include the analysis of exposure and trends, as well as assessing the effectiveness of the credit policy. The objective is to sustain a risk profile and sufficient minimum profitability to offset the anticipated default, for both individual clients and the overall portfolio, as determined by the Executive Committee and the Board of Directors. Moreover, it is tasked with overseeing the risk management systems and their implementation in the identification, measurement, control, and mitigation of risk exposure in either individual or similarly grouped operations.

Risk Management is specialized according to client characteristics, distinguishing between individualized clients (monitored by dedicated analysts) and clients with similar characteristics (standardized).

**\*Values expressed in thousands, except when indicated**<br>

&nbsp;&nbsp;&nbsp;&nbsp;• Individualized management – Conducted
by a designated risk analyst, who is responsible for the preparation of analyses, submission to the Risk Committee, and ongoing monitoring
of the client's progress. It applies to clients from the Global Wholesale Banking segment (Corporate and Santander Corporate & Investment
Banking - SCIB) and Commercial Banking (Portfolio clients, Companies 3, as well as GIU-Governments, Institutions, and Universities).

&nbsp;&nbsp;&nbsp;&nbsp;• Standardized management – Targeted
at individuals and companies not classified as individualized clients. It relies on automated decision-making models and internal risk
assessment frameworks, supplemented by commercial units and specialized analyst teams to address exceptions.

Macroeconomic factors and market conditions, as well as sector-wise and geographical concentrations, alongside the profiles of clients and economic forecasts, are also evaluated and considered for a proper assessment of credit risk.

**b.2) Measures and evaluation tools**

**Rating tools**

The Bank employs its proprietary rating models to assess the credit quality of a client or transaction. Each rating is linked to a probability of default or non-payment, determined based on the Bank's historical experience, to predict default. These scores/ratings are utilized in the credit risk approval and monitoring process.

The classification of credit exposures into distinct categories is conducted based on an analysis of the client's financial and economic circumstances, as well as other registration information that is regularly updated. New types of operations are subjected to a credit risk assessment and must be verified for compliance with the controls adopted by the Bank.

The ratings assigned to clients are periodically reviewed, incorporating the latest financial information and insights gained from the banking relationship. The frequency of these reassessments is heightened for clients who reach specific thresholds in automated alert systems, as well as for those designated for special monitoring. The rating tools are also continually reviewed and refined to ensure the accuracy of the ratings they assign is continually improved.

**Credit risk parameters**

We assess all loans with regard to the provision for impairment losses on credit risk. Loans are individually assessed for impairment or collectively assessed through grouping by similar risk characteristics. Loans that are individually evaluated for impairment losses are not assessed collectively.

To measure the impairment loss of loans assessed individually for impairment, we consider the conditions of the borrowers, including their economic and financial status, level of indebtedness, cash flow generation capacity, management quality, corporate governance, internal controls quality, payment history, industry experience, contingencies, and credit limits. Additionally, we evaluate asset characteristics, such as their nature and purpose, type, adequacy, and liquidity of collateral, drawing on historical impairment experience and other known circumstances at the time of assessment.

To measure the impairment loss on loans assessed collectively for impairment, we segregate financial assets into groups based on their credit risk characteristics and similarities. In other words, according to the segment, type of assets, collateral, and other factors related to historical impairment losses and other known circumstances at the time of assessment. The impairment loss is calculated using statistical models that incorporate the following factors:

Exposure At Default (EAD):is based on the gross carrying amount at the reporting date and, where applicable, adjusted to reflect the expected exposure at the time of default in accordance with IFRS 9.

Probability of Default (PD): denotes the likelihood of a counterparty failing to fulfill its obligation to repay the principal and/or interest. Within the framework of IFRS 9, this encompasses both the PD-12 months, which is the probability of the financial instrument defaulting within the next 12 months, and the lifetime PD, which is the probability of the transaction defaulting over its remaining term. The estimation of these parameters requires the consideration of relevant future information, as per the standard.

Loss Given Default (LGD): represents the loss incurred upon default. In other words, it quantifies the percentage of exposure that was not recoverable following a default event. The determination of LGD is primarily influenced by the collateral, which serves as a mitigator of the credit risk associated with each financial asset, and the expected future cash flows to be recovered. In accordance with the standard, forward-looking information must be considered in the estimation process.

Discount Rate: the rate applied to the estimated future cash flows over the expected lifespan of the asset, which corresponds to the net present value of the financial instrument relative to its carrying amount.

To estimate the aforementioned parameters, the Bank leveraged its expertise in developing internal models for the calculation of parameters for both regulatory and management purposes.

The table presented in **note 9.b** outlines the portfolio according to internal risk rating levels and their probability of default.

The expected loan losses, measured using sufficient and available historical data, are detailed below.

**b.3) Observed losses: credit cost measures**

Each month, the Bank estimates the losses associated with credit risk and subsequently compares these estimates with the actual losses incurred during the month. Periodic analyses are conducted to monitor and maintain control over credit risk.

To complement the use of admission and rating models, Banco Santander employs additional measures to support the prudent and effective management of credit risk, based on observed losses.

The cost of credit is calculated by adding the loan losses incurred over the fiscal year to the average loan portfolio for the same period.

**b.4) Credit risk cycle**

Banco Santander has a global perspective of its loan portfolio across all stages of the risk cycle, with a level of granularity that enables the assessment of the current risk situation and potential movements. This mapping is overseen by the Board of Directors and the Executive Committee of the bank, which are responsible for setting risk management policies and procedures, limits, and delegating authority, in addition to approving and supervising the department's operations.

The credit risk management process involves the identification, measurement, analysis, control, negotiation, mitigation, and decision-making on the risks incurred in the operations of the Bank and its affiliated entities within the Conglomerate. The credit cycle comprises three distinct stages:

&nbsp;&nbsp;&nbsp;&nbsp;• Pre-sales: encompasses the planning activities,
goal setting, assessment of Banco Santander's risk appetite, approval of new products, risk analysis, credit rating procedures, and definition
of limits;

&nbsp;&nbsp;&nbsp;&nbsp;• Sales: this involves the decision-making
process for pre-classified and specific operations; and

&nbsp;&nbsp;&nbsp;&nbsp;• After-sales: this includes the processes
of monitoring, measurement, and control, as well as the management of the recovery process.

**Planning and setting risk limits**

This process identifies the Bank's risk appetite by evaluating business proposals and assessing its risk position.

It is determined based on the risk appetite approved by the Bank's Management and its units.

In the context of individualized risks, the client constitutes the foundational level, for whom specific limits are set.

For SCIB clients, a pre-classification model is utilized, which is based on a system for measuring and monitoring economic capital. With respect to the Corporate segment, the operational limit model is applied, utilizing maximum nominal credit values.

For clients under standardized risk management, portfolio limits are established through loan management programs (LMP), a document that is pre-agreed upon by the business and risk departments, and approved by the Executive Committee. This document specifies the expected outcomes for the business in terms of risk and return, as well as the limits to which both the activity and risk management are subject. This client segment receives a more automated Risk treatment.

**Risk analysis and rating process**

Risk analysis is a prerequisite for the Bank's credit approval for clients. This analysis involves examining the counterparty's ability to fulfill its contractual obligations to the Bank, which includes assessing the client's credit quality, risk operations, solvency, and the intended return in light of the assumed risk.

This risk assessment is conducted at least annually, and may be revised more frequently if warranted by the client's risk profile (due to centralized alert systems or visits from the manager or credit analyst), or if there are specific transactions outside of the pre-classification.

**Decision-making on operations**

The decision-making process for operations is designed to analyze and implement measures in accordance with pre-established policies, factoring in the risk appetite and any significant elements of the operation for the purpose of assessing risk and return.

The Bank employs, among other methodologies, the RORAC (Risk-Adjusted Return on Capital) approach for analysis and pricing in its decision-making process concerning operations and business activities.

**Risk monitoring and control**

In the retail banking segment for individual customers, clients are systematically assessed through a daily credit scoring process.

This process enables the reassessment of credit exposure, allowing for increases in exposure for clients exhibiting good credit quality. In the event of detecting a deterioration in risk level, it automatically triggers actions for credit risk containment and the implementation of preventive measures.

In instances of individualized management, the preemptive detection of credit quality deterioration within an operation falls under the joint responsibility of the commercial manager and the risk analyst. Furthermore, risk monitoring is conducted through a continuous observation process, aimed at the early identification of incidents that may occur in the evolution of operations, clients, and their environment.

This monitoring may lead to the client's classification under SCAN (a system designed to differentiate management levels and dictate the appropriate actions on a case-by-case basis).

**\*Values expressed in thousands, except when indicated**<br>

**Risk control function**

The control function is executed by assessing risks from various complementary perspectives, with the main pillars being control by location, business area, management model, product, and process. This approach facilitates the identification of specific situations necessitating decision-making. The objective is to gain a comprehensive understanding of the Bank's loan portfolio across all stages of the credit cycle, with a degree of detail enabling the evaluation of the current risk situation and potential changes.

Shifts in the Bank's exposure to credit risk are continuously and systematically monitored. The effects of these changes on future exogenous situations, as well as those stemming from strategic decisions, are assessed with the aim of implementing measures that restore the loan portfolio's profile and value back to the parameters set by the Executive Committee.

**b.5) Credit Recovery**

Operational strategies and channels are determined based on the number of days past due and the respective amounts, resulting in a Responsibilities Map and always prioritizing, as the primary option, the customer's recovery.

Behavioral scoring tools are utilized to assess the collection performance of specific groups, aiming to reduce costs and enhance recovery efforts. These models are designed to estimate the likelihood of customer default by optimizing collection strategies, so that customers with a lower probability of recovery are targeted with timely interventions. In instances where there is a higher likelihood of repayment, the emphasis is placed on maintaining a healthy relationship with customers. All customers facing significantly overdue payments or those with restructured loans are subjected to internal restrictions.

Clients with higher volumes at Risk are assigned a portfolio-based recovery model, with commercial oversight and a recovery specialist.

**b.6) Credit risk from other perspectives**

Certain areas and/or specific perspectives on credit risk warrant the attention of specialists, in addition to the management of overall risk.

**Concentration risk**

Concentration risk is a critical factor in credit risk management. The Bank continuously monitors the concentration of credit risk within its portfolios, by economic sector, geographical location/country, customer groups, and product types.

The Risk Committee establishes risk policies and assesses the necessary exposure limits for the effective management of credit risk concentration within the portfolio. From a sector-wise perspective, the distribution of the corporate client portfolio is appropriately diversified.

The Risk Executive Vice Presidency at the Bank works in conjunction with the Strategic Finance Executive Vice Presidency in the management of loan portfolios. This involves reducing the concentration of exposures through various techniques, including maintaining guarantees to mitigate corporate risk, deploying derivatives for hedging purposes, and executing securitization transactions to optimize the portfolio's overall risk/return ratio.

**Credit risk from financial market operations**

This topic encompasses the credit risk associated with treasury operations conducted with clients, particularly credit institutions. These operations are carried out through financing products in the money market involving various financial institutions and by employing instruments held for the purpose of serving clients.

Risk management is conducted with the support of an integrated real-time system, enabling the Bank to ascertain, at any moment, the unused exposure limit with respect to any counterparty, any product, and any maturity across all units of the Bank.

Credit risk is measured at its current fair value and its potential value (the value of exposure, considering future shifts in relevant market factors). Consequently, the Equivalent Credit Risk (ECR) is defined as the sum of the net replacement value plus the future maximum potential value of the contracts.

**Social and Environmental Risk**

In order to promote a more controlled and safe scenario for our operations and also foster the development of businesses that adopt sustainable practices, Banco Santander permanently manages the risks involved in our activities and that may have an impact on the Organization, shareholders, customers, society and the environment.

In this sense, Banco Santander has a Social, Environmental and Climate Responsibility Policy (PRSAC), which establishes guidelines and consolidates specific policies for social, environmental and climate practices in business and in relationships with stakeholders. These practices include the analysis of social, environmental and climate risks, which is guided by the Social, Environmental and Climate Risk Policy (PORSAC), for granting credit to Wholesale customers and the Retail Companies 3 segment (one of the Bank's Legal Entity segments), which have credit limits or risk above R$7 million. These customers, both Wholesale and Retail, are classified into 14 service sectors, segregated into two risk levels: medium and high risk subsectors. This analysis also covers agricultural operations (including individual clients), real estate credit, projects, guarantees, acceptance and retention of clients, and mergers and acquisitions. The purpose of the Socio-environmental and Climate Risk analysis is to support and mitigate issues of operational risk, capital risk, credit risk, and reputational risk, always with an integrated risk perspective.

Since 2009, Santander has been a signatory to the Equator Principles, which are a set of guidelines used to analyze Socio-environmental and Climate Risks in the financing of large infrastructure and energy projects. The same set of socio-environmental criteria is applied to projects that do not fall within these principles. The aforementioned management structure is aligned with compliance with CMN resolutions no. 4,943/2021 and no. 4,945/2021, determining that organizations take a closer look at managing risks associated with social, environmental and climate issues, in addition to a Social, Environmental and Climate Responsibility Policy (PRSAC) and Social, Environmental and Climate Risk Policy (PORSAC)..

**b.7) Credit Management - Main changes**

Even with the challenging economic scenario, which resulted in higher default rates in certain segments, the Bank managed to maintain the good quality of its portfolio, adopting a more selective approach to granting credit and focusing on higher-profitability portfolios.

Below is a table illustrating the evolution of the main credit indicators.

---

The Bank incorporates forward-looking information in both its assessment of whether the credit risk of a financial instrument has substantially increased since its initial recognition and in its measurement of expected loan losses. Drawing on guidance from its internal committees and economic experts, and taking into account a range of actual and forecasted external information, the Bank develops a base scenario as well as other possible scenarios. This process involves projecting two or more additional economic scenarios and assessing the respective probabilities of each outcome. External information includes economic data and forecasts published by government agencies, monetary authorities, and selected analysts from the private sector and academia.

The base case represents the most probable outcome and aligns with the information the Bank uses for other purposes, including strategic planning and budget formulation. The alternative scenarios depict outcomes that are either more optimistic or more pessimistic. Periodically, the Bank conducts stress tests on more extreme shocks to refine its assessment of these alternative scenarios.

**c) Market Risk**

Market risk represents exposure to risk factors such as interest rates, exchange rates, commodity prices, stock market prices, and other financial instruments, contingent upon the product type, transaction volume, duration, contractual terms, and underlying volatility.

The Bank operates in accordance with global policies, framed within its risk tolerance perspective and aligned with its objectives in Brazil and internationally. To achieve this, it has developed its own Risk Management model, adhering to the following principles:

&nbsp;&nbsp;&nbsp;&nbsp;• Functional independence;

&nbsp;&nbsp;&nbsp;&nbsp;• Executive capability sustained by knowledge
and close customer relationships;

&nbsp;&nbsp;&nbsp;&nbsp;• Global reach of the function (diverse risk
types);

&nbsp;&nbsp;&nbsp;&nbsp;• Collective decision-making that evaluates
all possible scenarios without compromising outcomes with individual decisions, including the Executive Risk Committee for Brazil, which
establishes limits and approves operations, and the Executive Committee for Assets and Liabilities, responsible for the management of
capital and structural risks, encompassing country risk, liquidity, and interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;• Management and optimization of the risk/return
equation; and

&nbsp;&nbsp;&nbsp;&nbsp;• Risk management methodologies, such as Value
At Risk - VaR (historical simulation over 520 days, with a confidence level of 99% and a one-day time horizon), scenarios, sensitivity
of net interest income, sensitivity of fair value of equity, and contingency planning.

The Market Risk structure is part of the Risk Vice Presidency, an independent unit that implements risk policies in accordance with the directives from the Board of Directors and the Risk Division of the Santander Group Spain.

**c.1) Activities subject to market risk**

The measurement, control, and monitoring of market risk encompass all operations where asset risk is assumed. This risk arises from fluctuations in risk factors - including interest rates, exchange rates, equities, commodity prices, and the volatility of these factors - as well as from solvency and liquidity risks associated with the various products and markets in which the Bank operates.

The activities are segmented by type of risk, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. Financial
intermediation: this item encompasses financial services provided to clients, financial intermediation operations and positioning, particularly
in fixed-income securities, foreign exchange, and equities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;II. Balance
sheet management: the objective of balance sheet risk management is to stabilize the net interest income of the commercial area and the
economic value of the Bank, so as to maintain adequate liquidity and solvency levels. Risk is assessed based on the balance sheet's exposure
to interest rate movements and liquidity levels.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;III. Structural
Risks:

&nbsp;&nbsp;&nbsp;&nbsp;• Structural foreign exchange risk/earnings
hedge: exchange rate risk arising from the currency in which investments in consolidated and non-consolidated entities are made (structural
exchange rate). This item also includes positions taken to hedge against the foreign exchange risk in future earnings generated in currencies
other than the Brazilian Real (earnings hedge).

&nbsp;&nbsp;&nbsp;&nbsp;• Structural equity risk: this item includes
equity interests in both financial and non-financial and non-consolidated entities that may present an equity risk.

The Financial Management area is responsible for centrally managing balance sheet and structural risks by applying standardized methodologies tailored to the specific conditions of each market in which the Bank operates. Additionally, Financial Management directly manages currency risks arising from investments and holdings, as well as other foreign exchange risk operations originating from the bank's portfolio (Structural Foreign Exchange Risk). Decisions affecting the management of these risks are made through the ALCO (Asset Liability Committee) in the respective countries.

The purpose of the Financial Management area is to ensure the stability and recurring nature of both the net interest margin arising from commercial activities and the Bank's economic value, while maintaining adequate levels of solvency and liquidity.

Each of these activities is measured and analyzed using various tools to accurately reflect their risk profiles as precisely as possible.

**Interest Rate Risk**

The table below consolidates, by product, the cash flows from operations within our group of companies that earn interest income. These operations are reported at their book balance as of the closing dates for the years 2025 and 2024. It is not associated with the management of risks related to changes in interest rates or the mismatching of indices, which is conducted through the monitoring of market metrics. However, it facilitates the assessment of concentrations of maturities and potential risks. Below this, the balances of the same products are presented at their redemption value at maturity, with the exception of the line concerning receivables and liabilities from derivative contracts.

**c.2) Methodologies**

**Financial Intermediation**

Banco Santander has been calculating the minimum capital requirement for market risks using an internal model since its approval by the Brazilian Central Bank in May of 2018.

The standard methodology for measuring and controlling market risks in financial intermediation activities conducted by Banco Santander in 2025 and 2024 was Value at Risk (VaR), which quantifies the maximum expected loss at a specified confidence level over a given period. This methodology employs a standard historical simulation with a confidence level of 99 and a one-day horizon. Statistical adjustments were made to efficiently incorporate the most recent events impacting the level of risk assumed.

Specifically, the Bank uses a two-year time window of daily data obtained retroactively to the reference date for the VaR calculation. Two values are calculated daily: one applying an exponential decay factor that gives less weight to observations further from the effective date, and another with uniform weights for all observations. The reported VaR will be the higher of these two values.

**\*Values expressed in thousands, except when indicated**<br>

VaR is not the only metric available for assessing the risk exposure of an institution. It is favored for its simplicity in calculation and effectiveness as a benchmark for the level of risk faced by the Bank. Nevertheless, the Bank employs additional metrics and methodologies to enhance its control over risk across all markets in which it operates.

Among these measures, scenario analysis is particularly noteworthy. It entails defining behavioral scenarios for various financial variables and assessing their impact on results by applying them to the Bank's operations. These scenarios may either replicate past events (such as crises, for example), or establish plausible scenarios that are not based on past events. A minimum of three types of scenarios—plausible, severe, and extreme—are established. Together with VaR, these scenarios enable a much more comprehensive assessment of the risk profile.

The positions are tracked daily through comprehensive oversight of portfolio fluctuations, with the purpose of identifying potential incidents and immediately rectifying them.

A daily profit and loss statement is an excellent indicator of risk, as it enables the monitoring and detection of the impact of changes in financial variables on portfolios.

Finally, in managing credit activities (actively traded credits - trading portfolio) and derivatives, given their unique characteristics, specific measures are assessed. For derivatives, these measures include sensitivities to fluctuations in the underlying asset's price (delta and gamma), volatility (vega), and time (theta). In the case of credit management activities (actively traded) within trading portfolios, the controlled measures encompass sensitivity to spread, jump-to-default risk, and position concentration by rating level.

**c.3) Balance sheet management**

**Interest rate risk**

The Bank assesses the sensitivity of the net interest margin (financial margin) and fair value of equity to interest rate fluctuations. This sensitivity arises from the mismatch between the maturity and interest rate revision dates of the various balance sheet items.

Based on the balance sheet's interest rate position, its accounting classifications and taking into account the market's current situation and market outlook, financial measures are implemented to align this position with the Bank's desired stance. These measures may range from taking market positions to defining the interest rate characteristics of commercial products.

The measures employed by the Bank to manage risk, or exposure to interest rates in these activities, include the interest rate gap, which assesses the sensitivity of the net interest margin (NIM) and fair value of equity (MVE) to fluctuations in interest rate levels, the duration of equity, Value at Risk (VaR), Earnings at Risk (EaR), portfolio stress, and scenario analysis.

**Interest Rate Gap between Assets and Liabilities**

The interest rate gap analysis focuses on the mismatches between the revaluation periods of balance sheet items (assets and liabilities) and off-balance sheet items. This analysis provides a basic representation of the balance sheet structure and enables the identification of interest rate risk concentrations across various maturities. Furthermore, it serves as a useful tool for estimating the potential impact of fluctuations in interest rates on the net interest margin and the institution's equity value.

All items, whether on the balance sheet or off the balance sheet, must be classified according to flows and reorganized based on the point of price revaluation and their maturities. In instances where a maturity date is not specified by contract, an internal model for analyzing and estimating its duration and sensitivity will be utilized.

**Sensitivity of Net Interest Margin (NIM)**

The sensitivity of net interest margin measures the change in expected receivables for a specific period (12 months) in response to a shift in the interest rate curve.

The calculation of the net interest margin sensitivity is performed by simulating the margin in scenarios of changes in interest rate curves and comparing it with the current scenario. Sensitivity is the difference between the two calculated margins.

**Sensitivity of Fair value of Equity (MVE)**

The sensitivity of fair value of equity is a supplementary measure to the sensitivity of net interest margin.

It assesses the implicit interest rate risk in equity, based on the impact of interest rate fluctuations on the present values of financial assets and liabilities.

**Value at Risk (VaR) and Earnings at Risk (EaR)**

It is determined at the 99% percentile of the MVE's loss distribution function, calculated by considering the current fair value of positions, based on the monthly returns obtained in the last two years.The risk factors are interest rates and credit spreads, for the applicable portfolios.

A similar methodology is also applied to calculate the maximum loss in NII (EaR), aiming to assess the interest rate risk in terms of its impact on both economic value and net interest margin.

The unit checks both vectors, and the composition is done by considering the larger of the two.

**Portfolio Stress**

In addition to the previous metrics, an additional stress is also generated, focused on portfolios whose accounting is based on market value (either with a counterpart in reserves or with a counterpart in results) within the bank portfolio. These positions – valued at market – are stressed according to quarterly returns from historical scenarios of the last 7 years, with a confidence level of 95%, separated by risk factor (interest rate and/or credit spreads) and by index.

To the result of the stress of the market-valued positions is added the value of the stressed margin for the positions accounted for at their amortized cost, also with a quarterly horizon. That is, the final metric is composed of the sum between Market Value Stress for market-marked positions and this financial margin for positions accounted for at amortized cost.

**c.4) Liquidity risk**

Liquidity risk relates to the Bank's ability to fund commitments undertaken at reasonable market prices and to execute its business plans with stable funding sources.

**Liquidity management of Banco Santander**

For liquidity management and control, Banco Santander employs both short-term and long-term metrics, as well as metrics for stress scenarios, which are capable of measuring a robust liquidity buffer, ensuring the Bank can comfortably meet its obligations to the market and shareholders. Accordingly, in this regard, we note:

**Short-term metrics and liquidity stress:**

*a. LCR*

Banco Santander employs the "Liquidity Coverage Ratio" (LCR) in its liquidity risk management strategy. The LCR is a short-term liquidity measure for a stress scenario spanning 30 days, calculated as the ratio of high-quality liquid assets to net cash outflows over 30 days.

The total High Quality Liquidity Assets - HQLA (Liquid Assets) primarily consist of Brazilian federal government securities and compulsory reserve yields. Net outflows are mainly due to deposit losses, partially offset by inflows, predominantly loans.

*b. Liquidity stress scenarios*

Liquidity management entails the analysis of financial scenarios to assess potential liquidity issues, which demands the development and examination of scenarios in crisis conditions. The Stress Test is the model employed for this analysis.

The Stress Test evaluates the financial structure of the institution and its capacity to withstand and respond to more extreme scenarios.

The purpose of the Liquidity Stress Test is to allow for the simulation of adverse market conditions, thereby enabling the assessment of their impacts on the institution's liquidity and payment capacity. Consequently, it aims to preemptively identify solutions or avoid positions that could significantly compromise liquidity in volatile scenarios.

Scenarios are defined based on the analysis of market behavior during previous crises. Four crisis scenarios are formulated, each with varying levels of intensity.

Following the analysis of stress models, the concept of minimum liquidity was established as the amount sufficient to cover liquidity losses over a specified horizon of days, across all simulated crisis scenarios.

**Long-term metric:**

Its purpose is to assess the stability of funding sources relative to committed assets. The Net Stable Funding Ratio (NSFR), a metric developed by the Bank for International Settlements (BIS) and adapted by the local regulator, aims to determine, through specified percentages, whether the institution maintains a stable funding source to support its assets. This metric applies varying weightings based on term, customer segment, and product type. It is calculated on a monthly basis by the institution.

*c. Liquidity ratios*

To support management, certain liquidity ratios, including counterparty concentration ratios and segment concentration ratios, are calculated on a monthly basis.

**Funding from Customers**

Banco Santander has diverse sources of funding, both in terms of products and customer mix, with a healthy distribution across segments. Total customer funding currently stands at R$819 billion, marking an increase from the previous volume of 2024. This growth is primarily attributed to a significant rise in term deposit inflows and new bond issuances.

**Scenario analysis/contingency plan**

Based on the results of the Stress Test, the Bank formulates its Liquidity Contingency Plan, comprising a formal set of preventive and corrective actions to be deployed in the event of a liquidity crisis. The activation of the Plan is contingent upon the monitoring of internal parameters that reflect the Bank's market and liquidity conditions. These parameters are used to identify different levels of crisis severity, thereby determining whether there is a need to initiate the activation process.

Following the identification of a crisis, clear communication is established among the internal departments capable of executing corrective actions to mitigate the arising issues. These corrective actions, aimed at generating liquidity to resolve or alleviate the effects of the crisis, are selected based on their complexities, implementation timelines, and impact on liquidity.

The parameters and measures of this Plan are subject to review whenever necessary, with a minimum review period of one year.

**c.5) Structural foreign exchange risk/earnings hedge/structural equity risk**

These activities are monitored by measuring positions, VaR, and results.

**c.5.1) Complementary measures**

**Testing and calibration measures**

Back-testing consists of a comparative analysis between Value at Risk (VaR) estimates and daily "clean" results (portfolio profits or losses at the end of the previous day, valued at the next day's prices) and "dirty" results (managerial income incorporating costs, intraday results, and carry). The purpose of these tests is to verify and provide a measure of the accuracy of the models used in the VaR calculation.

The back-testing analyses conducted by Banco Santander are in compliance, at a minimum, with the BIS recommendations concerning the verification of internal systems used in the measurement and management of financial risks. The Bank also engages in hypothesis testing, including tests for outliers, normality tests, Spearman correlation, and measures of average excess, among others. The assessment models are regularly calibrated and tested by a specialized unit.

**c.6) Control system**

**Limit setting**

The limit-setting process is conducted in conjunction with budgeting activities and serves as a mechanism to determine the assets and liabilities available for each business activity. This process is dynamic, adjusting to the level of risk deemed acceptable by Management. The framework for setting limits entails devising a process that takes into account, among other factors, the following aspects:

Efficiently and comprehensively identify and delineate the principal types of financial risks generated, ensuring alignment with business management and the defined strategy.

Quantify and communicate to the business divisions the levels and profiles of risk deemed acceptable by Management, in order to prevent undesired risks.

Provide business areas with the flexibility to undertake financial risks efficiently and timely, in response to market changes and business strategy adjustments, always within the risk thresholds deemed acceptable by the institution.

Enable business generators to assume risks at a volume that is both prudent and adequate to achieve the budgeted results.

Specify the range of products and underlyings that each Treasury unit is authorized to operate with, taking into account factors such as valuation models and systems, and the liquidity of the instruments involved.

**c.7) Risks and results in 2025**

**Financial Intermediation Activities**

In 2025, he Bank's trading portfolio's average VaR was R$(2,605) million . The dynamic management of this profile allows the Bank to adjust its strategy to capitalize on opportunities presented by an uncertain environment.

**c.7.1) Balance sheet management**

**Interest risk**

**Convertible currencies**

At the end of 2025, the interest rate risk, as measured by the one-year sensitivity of the net interest margin to a parallel increase of 100 basis points across Banco Santander's portfolios, was primarily concentrated in the Brazilian Real interest rate curve, resulting in a negative impact of R$(369) million.

Additionally, at the close of 2025, the interest rate risk, as measured in terms of the company's fair value sensitivity to a parallel increase of 100 basis points applied to Banco Santander on the Brazilian Real interest rate curve, resulted in a negative impact of R$(1,664) million.

**Quantitative risk analysis**

The interest rate risk in balance sheet management portfolios, as measured by the sensitivity of the net interest margin, over a one-year period with a parallel increase of 100 basis points in the interest rate curve, decreased by R$428 million from 2024 to 2025, reaching a peak of R$888 million in February of 2025. The sensitivity of value decreased by R$979 million during the year of 2025, achieving a maximum level of R$2,687 million in January of 2025. The key factors that occurred in the year 2025 and influenced the decrease in sensitivities were the hedging of credit production and the updating of the non-maturing liabilities model.

**c.8) Sensitivity analysis**

Risk management is concentrated on portfolios and risk factors, in accordance with Brazilian Central Bank regulations and international best practices.

Financial instruments are classified into trading books (Trading Book) and banking books (Banking Book), as performed in the management of market risk exposure, in line with market best practices and the Brazilian Central Bank's criteria for operation classification and capital management. The trading book encompasses all transactions involving financial instruments and commodities, including derivatives, held for trading purposes. The banking book includes structural operations stemming from the various business lines of Banco Santander and their corresponding hedges, if any. Consequently, in accordance with the nature of Banco Santander's activities, the sensitivity analysis has been split between the trading and banking portfolios.

Banco Santander conducts sensitivity analysis of its financial instruments in accordance with IFRS 7, taking into account market information and scenarios that could adversely affect the Bank's positions.

The summary tables presented below encapsulate sensitivity values generated by Banco Santander's corporate systems, relating to the trading book and the banking book, for each portfolio scenario on December 31, 2025.

**d) The Bank's operations are highly dependent on the proper functioning of its information technology systems**

The Bank's operations are significantly dependent on the accurate and efficient processing of a large volume of transactions, executed by its information technology systems, along with its reliance on digital technologies, computing services, email, software, and networks, as well as the secure processing, storage, and transmission of confidential and other information within computer and network systems.

The proper functioning of the Bank's financial control, risk management, accounting, customer service, and other data processing systems is critical for its operations and its ability to compete effectively.

**e) Independent Structure**

Banco Santander maintains an operational risk management and internal control structure in accordance with CMN Resolutions No. 4,557/2017 and No. 4,968/2021, respectively, as well as the guidelines of the Basel Committee and corporate definitions of the Santander Group. Operational risks are defined as the possibility of losses resulting from failures, deficiencies or inadequacy of internal processes, people, systems or external events, including legal risk, but excluding strategic and reputational risks.

**e.1) Management Model**

The management model is based on the RCSA (Risk and Control Self-Assessment) methodology and the Basel Committee guidelines, structured in three lines of governance. The first line (business and support areas) is responsible for identifying, assessing, and managing risks in its activities. The second line (Operational Risk & Internal Controls) performs independent supervision, validation, and challenge of assessments, as well as monitoring and reporting consolidated exposure. Operational risk appetite is approved by the Board of Directors and reviewed periodically.

The model integrates the following management tools: definition of operational risk appetite, capture and evaluation of loss events (internal and external), training and culture, evaluation of products and services, operational risk self-assessment (RCSA), scenario analysis, risk indicators and controls, and internal controls.

**\*Values expressed in thousands, except when indicated**<br>

Additionally, the Internal Controls Model is based on the COSO (Committee of Sponsoring Organizations of the Treadway Commission) methodology, encompassing strategic, operational, financial disclosure, and compliance controls, in accordance with the requirements of the Central Bank of Brazil (BACEN), the Securities and Exchange Commission (CVM), the Brazilian Stock Exchange (B3), the Superintendence of Private Insurance (SUSEP), and the Sarbanes-Oxley Act (SOX).

**e.2) Governance**

The governance structure comprises the Board of Directors, which approves the operational risk model and appetite, and the Risk Control Committee, responsible for overseeing operational risk management. The Senior Forum on Internal Controls and Operational Risks (FSCIRO) aims to govern, analyze, and deliberate on the most relevant and regulatory strategies and issues. The Internal Controls & Process Quality Forum aims to monitor the internal control environment and risk profile. The main risks and control profile are reported periodically and, when applicable, escalated to the Risk Control Committee, the Audit Committee, and the Board's Risk and Compliance Committee.

The model relies on the ORM (Operational Risk Management) Networks community, structured in three levels: (i) RPO (Risk Pro Officer), responsible for reporting to the strategic level of the Executive Board on the monitoring of operational risk issues; (ii) RPA (Risk Pro Agent), responsible to the Executive Vice Presidency regarding the operational risk management and control model; and (iii) Operational Risk Assistants and Specialists, who work within the operational perimeter and on risks that are transversal to the organization, respectively.

The Operational Risks and Internal Controls area ensures the dissemination of a risk culture and the coordinated execution of management activities across all governance lines.

**e.3) Differentiating factor**

The Operational Risk & Internal Control area invests in the development, training and updating of its professionals to respond to changes identified in the business environment and provides training to other professionals through courses on the Intranet, in-person and virtual in real time. For in-person and virtual in real time, we prioritize the provision of training aimed at fostering the culture of Operational Risk management, Internal Controls, training to capture operational losses, among others.

These achievements contribute significantly to Banco Santander Brasil achieving its strategic and operational objectives in a consistent manner, with knowledge regarding the exposure to operational risks assumed and a controlled environment, maintaining the bank's low-risk profile and ensuring the sustainable development of its operations. The Bank highlights:

&nbsp;&nbsp;&nbsp;&nbsp;• Mandatory training for all Banco Santander
employees, through the Santander Academy, on Operational Risks and Internal Controls.

&nbsp;&nbsp;&nbsp;&nbsp;• Creation, dissemination and maintenance
of Instruction Manuals, allowing corporate dissemination for everyone's commitment.

&nbsp;&nbsp;&nbsp;&nbsp;• Coordination of the annual process for the
preparation of operational risk loss forecasts and definition of action plans to mitigate these losses.

&nbsp;&nbsp;&nbsp;&nbsp;• Development of key indicators for the purpose
of monitoring the main operational risks.

&nbsp;&nbsp;&nbsp;&nbsp;• Composition of governance lines with the
"ORM - Operational Risk management" Networks: "RPO-Risk Pro Officer", whose role is to report to the executive
the monitoring of Operational Risk issues at the strategic level of the Executive Board, the "RPA-Risk Pro Agent" who is responsible
for the VPE regarding the Operational Risk Management and Control Model and "Operational Risk Assistant" covering the RO perimeter
and "Specialists" for cases where the operational risk is transversal to the organization.

**e.4) Communication**

The Operational Risk & Internal Control area is part of Banco Santander's Governance structure and maintains a periodic communication and reporting process for Management through the Senior Forum on Internal Controls and Operational Risks (FSCIRO) and the RO Meeting. This process includes the presentation of materialized events, main risks, corrective action plans and information on the Internal Controls environment, ensuring transparency and knowledge to the governance forums. Additionally, the main risks (materialized and emerging) are reported and escalated, when applicable, to the Risk Control Committee and the Audit Committee and the Risk and Compliance Committee of the Board.

**f) Reputation Risk**

**f.1) Reputation Risk**

Reputation risk is defined as the risk of a negative economic impact, either current or potential, derived from an unfavorable perception of the Bank by employees, customers, shareholders/investors, and society at large.

Reputational risk may emerge from a variety of sources and, frequently, results from other risk events. Typically, these sources are associated with the business and other support activities undertaken by Santander, as well as the economic, social, or political landscape, or even incidents triggered by competitors that could impact the Bank.

**f.2) Compliance**

It is defined as legal risk, the risk of regulatory sanctions, financial loss, or reputational damage that an institution may face due to failure in complying with laws, regulations, codes of ethics and conduct, and best banking practices. Compliance risk management is preventive in nature and includes monitoring, educational initiatives, advisory, risk assessment, and corporate communication related to the rules and legislation applicable to each business area.

**f.3) Operating guidelines**

**a. Compliance Principles - Ethics and conduct in the securities markets**

Ethical principles and parameters are contained in internal policies made available and disseminated to all. The Code of Ethics applies to all employees of the Organization, and the Code of Conduct in the Securities Markets is adhered to by all those considered close to the Securities Market. Channels for clarification and reporting are available, in addition to monitoring and controls that are applied in a way that ensures adherence to the rules by all employees.

**b. Anti-Money Laundering and Counter-Terrorism Financing**

Our policy for preventing money laundering and combating the financing of terrorism is based on knowledge and rigor applied to the acceptance of our clients, complemented by the continuous monitoring of all transactions in which the Bank is involved. This concern is reflected in the management's involvement through the AML Operational Committee and the Ethics and Compliance Committee, which meets monthly to discuss matters related to the subject. The committee is directly involved in client acceptance processes and in reporting suspicious situations.

**c. New products and services and suitability**

All new products and services are analyzed internally by different technical areas, ensuring multidisciplinary risk mapping, and subsequently approved by the Local Marketing Committee (CLC), composed of Santander executives. After analysis and approval, the new products and services are subject to monitoring and testing to mitigate any potential misconduct risks in marketing.

**g) Compliance with the Prudential Regulatory Framework**

Santander Brasil maintains an integrated risk and capital management process that supports strategic decision-making and ensures adherence to the guidelines established by CMN Resolution No. 4,557 and other complementary regulations of the current prudential framework. This process promotes the efficient allocation of capital resources, aligning with corporate objectives related to solvency, sustainability of prudential ratios, and shareholder value creation.

Brazil's active participation in the Basel Committee on Banking Supervision (BCBS) drives regulatory convergence and the timely adoption of international prudential standards. In line with this dynamic regulatory environment, Santander Brasil is dedicated to the continuous improvement of its capital management processes, methodologies, and practices, seeking to maintain full compliance with market benchmarks, supervisory standards, and international best practices.

The Institution's capital management is a structured, continuous, and forward-looking process, encompassing activities of planning, evaluation, control, and monitoring of the capital necessary to address the material risks of the Prudential Conglomerate. This process includes:

&nbsp;&nbsp;&nbsp;&nbsp;• an assessment of the minimum capital requirements
for Pillar 1 risks (credit, market and operational);

---

**\*Values expressed in thousands, except when indicated**<br>

&nbsp;&nbsp;&nbsp;&nbsp;• The development and improvement of methodologies
for quantifying additional capital related to Pillar 2 risks;

&nbsp;&nbsp;&nbsp;&nbsp;• The execution of the Internal Capital Adequacy
Assessment Process (ICAAP), including the integrated analysis of risks and capital;

&nbsp;&nbsp;&nbsp;&nbsp;• The projection, monitoring, and reporting
of prudential indicators;

&nbsp;&nbsp;&nbsp;&nbsp;• The preparation and updating of the Capital
Plan;

&nbsp;&nbsp;&nbsp;&nbsp;• The preparation of capital contingency plans,
a Recovery Plan, and an Organized Exit Plan;

&nbsp;&nbsp;&nbsp;&nbsp;• Conducting stress tests, encompassing scenarios
of increasing severity and sensitivity analyses;

&nbsp;&nbsp;&nbsp;&nbsp;• and the preparation of the Quarterly Risk
and Capital Management Report (Pillar 3), in accordance with prudential transparency requirements.

With this structure, Santander Brasil ensures that capital management remains integrated with risk management, aligned with regulatory requirements and capable of sustaining the institution's financial resilience in different macroeconomic and business scenarios.

**g.1) Internal validation of risk models**

Internal validation is a central step in the lifecycle of risk models and a requirement for their approval by supervisory authorities. At Banco Santander, this process is conducted by a specialized and independent area, responsible for evaluating the suitability, robustness, and usefulness of the models for regulatory and management purposes, as well as their alignment with the Bank's strategy and risk profile.

The Internal Validation area provides support to risk committees and Senior Management by offering qualified and independent technical opinions, informing decisions regarding the authorization and continued use of internal templates.

The scope of validation covers risk models for Credit, Market, ALM, Operational Compliance, Pricing, Provisions, Economic Capital, and other models relevant to ICAAP, considering methodological, technological, data quality, performance, use, and governance aspects.

The Internal Validation function is aligned with the guidelines of the Basel Committee, the Bank of Spain, the European Central Bank, and the Central Bank of Brazil, maintaining segregation of duties from Internal Audit. Internal Audit, as the third line of defense, independently assesses the adequacy of the methodologies and the effective implementation of the validation processes.

**g.2 Capital Management**

Capital management considers regulatory and economic aspects and aims to achieve a cost-efficient and compliant capital structure, meeting the requirements of regulatory bodies and contributing to achieving the rating targets of rating agencies as well as the expectations of investors.

**h) Economic Capital**

**h.1) Main objectives**

The development of economic capital models in the financial world seeks to address a fundamental challenge of regulatory capital: Risk Sensitivity.

In this context, economic capital models are specifically crafted to produce risk-sensitive estimates, facilitating enhanced precision in risk management, as well as more effective allocation of economic capital across Banco Santander's business units.

Banco Santander has concentrated its efforts on developing a robust economic capital model that is seamlessly integrated with business management. The primary objectives of Banco Santander's economic capital framework are the following:

1 - Consolidate Pillar I and other risks impacting the business into a single quantitative model, while also determining capital estimates by establishing correlations among various risks.

2 - Quantify and monitor fluctuations across distinct risk types.

3 - Distribute capital consumption among the main portfolios and manage the efficiency of Return on Risk-Adjusted Capital (RORAC).

4 - Estimate the Economic Value Added for each business unit. Economic profit must exceed the Bank's cost of capital.

5 – Compliance with regulatory standards in the locations where the Bank operates during the Pillar II review process conducted by supervisory authorities.

**h.2) Economic Capital Model**

In the determination of economic capital, it is the Bank's duty to specify the level of loss to be covered. Accordingly, a requisite confidence interval is applied to ensure the continuity of operations.

The risk profile in Brazil is distributed among Credit, Market, ALM, Business, Operational and Material Assets risks. However, in order to anticipate the changes proposed in Basel III, new risks were incorporated into the model: Intangibles, Pension Funds (defined benefit) and Deferred Tax Assets, which allow the Bank to adopt an even more conservative and prudent position.

|:---|:---|:---|
| **% Capital** | **2025** | **2024** |
| **Risk Type** |  |  |
| Credit | 49% | 48% |
| Market | 2% | 2% |
| ALM | 3% | 5% |
| Business | 9% | 8% |
| Operational | 5% | 7% |
| Fixed Assets | 1% | 1% |

| Pension Funds | 1% | 1% |
| Deferred Tax Assets | 29% | 26% |
| **TOTAL** | **100%** | **100%** |

---

However, as a commercial bank, Credit is Banco Santander's main source of risk and the evolution of its portfolio is one of the main factors for its fluctuation.

RoRAC

Banco Santander Brasil has been using RORAC, with the following objectives:

- Analyze and establish a minimum price for operations (admissions) and customers (monitoring).

- Estimate the capital consumption for each client, economic group, portfolio, or business segment to optimize the allocation of economic capital, thereby maximizing the Bank's efficiency.

- Measure and track the performance of the business.

- To assess the operations of global clients, the calculation of economic capital incorporates specific variables employed in determining expected and unexpected losses. These variables include:

- Counterparty rating.

- Maturity.

- Guarantees.

- Nature of financing.

Economic value added is determined by the cost of capital. To generate value for shareholders, the minimum return from operations must exceed Banco Santander's cost of capital.

The Board of Directors of Banco Santander, at a meeting held on January 9, 2026, approved the proposal of the Banco Santander Executive Board, subject to ratification by the Ordinary General Meeting, for the distribution of Interest on Equity in the amount of R$2,000,000,000 two billion reais), based on the balance of the Company's Dividend Equalization Reserve. Shareholders registered with the Bank at the end of the day on January 20, 2026 (inclusive) were entitled to Interest on Equity. Therefore, starting on January 21, 2026 (inclusive), the Bank's shares were traded "Ex-Interest on Equity". The Interest on Equity was paid starting on February 5, 2026. The Interest on Equity was fully imputed to the minimum mandatory dividends distributed by the Bank for the fiscal year 2026, without any remuneration for monetary adjustment.

**a) Impairment of loans and receivables and financial assets measured at amortized cost**

This refers to the adjustment resulting from the estimated expected loss on the portfolio of assets subject to impairment, loan commitments to be disbursed, and financial guarantee agreements, determined based on the criteria described in the accounting practice note and in accordance with IFRS 9. These criteria differ in certain aspects from those adopted under Bacen GAAP, which uses the regulatory limits defined by the Central Bank (Bacen), in addition to the difference in the scope of the calculation basis for these losses, which for IFRS purposes considers other assets besides those foreseen by Bacen. In 2025, the effects of the initial adoption of CMN Resolution No. 4,966/2021 on provisions for losses associated with credit risk were reversed.

**b) Financial asset categories**

As outlined in the note on accounting practices, IFRS 9 mandates the identification of business models associated with each portfolio, as well as the execution of the SPPI test to ascertain whether the cash flows from an asset consist exclusively of payments for principal and interest, for the purpose of classifying the asset within the appropriate financial asset categories. In contrast, BRGAAP allows for certain differences in the categorization of these financial assets and also considers Management's intention as a criterion for classification. Additionally, the criteria for reclassification across categories differ between the two accounting standards.

**\*Values expressed in thousands, except when indicated**<br>

**c) Deferral of banking fees, commissions, and other financial costs using the effective interest rate method**

Under IFRS, bank fees, commissions, and related financial costs, which are included in the effective interest rate of financial instruments measured at amortized cost, are recognized in the income statement over the validity period of the respective contracts. In contrast, under BRGAAP, these fees and expenses are recognized directly in the income statement upon receipt or payment.

**d) Reversal of goodwill amortization**

Under BRGAAP, goodwill is systematically amortized over a period of up to 10 years, subject to impairment testing at least once a year, or more frequently if additional evidence arises. Under IFRS, as per IAS 38 "Intangible Assets", goodwill is not amortized but is tested for impairment to ascertain its recoverable amount at least annually, and whenever there is an indication of a potential reduction in its recoverable value. The tax amortization of Banco Real's goodwill represents a permanent and definitive difference between the accounting and tax bases, as the possibility of utilizing future funds to settle a tax liability is considered remote by Management, a position supported by the opinion of specialized external advisors. Consequently, the tax amortization of goodwill is permanent and definitive, and thus, the recognition of a deferred tax liability does not apply as per IAS 12 – Income Taxes, with respect to temporary differences.

**e) Recognition of purchase price adjustments**

As part of the purchase price allocation for acquisitions of entities, notably in the acquisition of Banco Real, in accordance with IFRS 3 "Business Combinations" standards, the Bank reassessed the acquired assets and liabilities at fair value, including identifiable intangible assets with defined useful lives. In contrast, according to BRGAAP, in a business combination, assets and liabilities are recorded at their book value. The adjustments to the purchase price allocation primarily relate to the valuation of assets in the loan portfolio. The initial recording of the loan values at fair value resulted in an adjustment to the yield curve of the portfolio compared to its nominal value, which is recognized over the respective average realization period.

**f) Option to Acquire Equity Instrument**

In the context of the transaction, Banco Santander granted the shareholders of Getnet S.A. and Banco Olé Consignado a put option for all the shares issued by Getnet S.A. and Banco Olé Consignado that they held. In accordance with IAS 32, a financial liability was recognized for the commitment made, offset against a specific equity account, in the amounts of R$950 million and R$67 million, respectively. The options were subsequently updated, with their effects recognized in the income statement. On December 19, 2018, Banco Santander and the Minority Shareholders of Getnet S.A. signed an amendment to the Share Purchase and Sale Agreement and Other Covenants of Getnet S.A., whereby Banco Santander committed to acquiring all the shares from the Minority Shareholders, representing 11.5% of the share capital of Getnet S.A., for the amount of R$1,431,000. The acquisition was approved by Brazilian Central Bank on February 18, 2019 and completed on February 25 2019, resulting in Banco Santander holding 100% of the shares representing the share capital of Getnet S.A. On March 14, 2019 the minority shareholder of Banco Olé Bonsucesso Consignado S.A. expressed their intention to exercise the put option stipulated in the Investment Agreement, signed on July 30, 2014, to sell their 40% stake in the share capital of Olé Consignado to Banco Santander (Brasil) S.A. On December 20, 2019 the parties entered into a binding agreement for the acquisition by Banco Santander of all the shares issued by Bosan Participações S.A., for a total value of R$1.6 billion, payable on the closing date of the transaction. On January 30, 2020, the name of Banco Olé Bonsucesso Consignado S.A. was changed to Banco Olé Consignado S.A. On January 31, 2020, the Bank and the shareholders of Bosan Participações S.A. finalized the definitive agreement and signed the share purchase and sale agreement for 100% of the shares issued by Bosan, through the transfer of Bosan's shares to the Bank and payment to the sellers in the total amount of R$1,608,773 As a result, the Bank has become, both directly and indirectly, the holder of 100% of the shares in Banco Olé.

**g) Santander Serviços (Santusa) acquisition goodwill**

Under IFRS 3 "Business Combinations", when a parent company acquires additional shares or other equity instruments of an entity it already controls, this amount must be recognized as a reduction in its equity. Under BRGAAP, this amount must be recorded on the balance sheet as goodwill or as a bargain purchase in the acquisition of the investment, which represents the difference between the acquisition cost and the equity value of the shares.

**h) Reclassification of financial instruments at fair value through profit or loss**

Under BRGAAP, all loans, financings, and deposits are accounted for at amortized cost. Under IFRS, as per IFRS 9 "Financial Instruments: Recognition and Measurement," financial instruments may be measured at fair value and included in the category "Other financial instruments at fair value through profit or loss." This approach aims to eliminate or significantly reduce the accounting mismatch in recognition or measurement arising from the valuation of assets or liabilities or the recognition of gains or losses on these assets/liabilities on different bases, which are managed and their performance evaluated based on fair value. Consequently, the Bank has classified loans, financings, and deposits that meet these criteria as "fair value through profit or loss," as well as certain debt instruments classified as "available for sale" under BRGAAP. The Bank has adopted this classification basis under IFRS, as it effectively eliminates an accounting mismatch in the recognition of income and expenses.

## Exhibit 2.5

**Exhibit 2.5**

**DESCRIPTION OF THE REGISTRANT'S SECURITIES<br> REGISTERED PURSUANT TO SECTION 12 OF THE<br> SECURITIES EXCHANGE ACT OF 1934**

**<u>Description of Capital Stock</u>**

The following description of Banco Santander (Brasil) S.A. ("Santander Brasil")'s capital stock is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to Santander Brasil's By-laws, an English translation of which is incorporated by reference as Exhibit 1.1 to the Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission, or the "SEC," on February 27, 2026, as well as on the legislation and regulations applicable to companies and the Brazilian capital market currently in effect. Santander Brasil encourages you to read the By-laws for additional information. Capitalized terms used and not defined hereinafter shall have the meanings ascribed to them throughout the Annual Report on Form 20-F.

**Issued Share Capital**

Santander Brasil's share capital is represented by common and preferred shares both without par value. Each common share gives its holder the right to a vote at general meetings. However, the preferred shares do not grant voting rights in Santander Brasil's shareholders' general meetings, except as related to certain matters provided for in its By-Laws (see "Rights of Common Shares and Preferred Shares" below).

There are no outstanding bonds or securities convertible into shares.

As of December 31, 2025, Santander Brasil had a share capital of R$65,000,000,000 represented by 3,805,028,571 outstanding common shares and 3,666,169,560 outstanding preferred shares.

**Rights of Common Shares and Preferred Shares**

Each common share gives its holder the right to a vote at general meetings, however, the preferred shares do not grant voting rights in Santander Brasil's shareholders' general meetings, except as related to the following matters:

&nbsp;&nbsp;&nbsp;&nbsp;· change of corporate status, merger, consolidation or spin-off;

&nbsp;&nbsp;&nbsp;&nbsp;· approval of agreements entered into between Santander Brasil and its controlling shareholder, directly or indirectly, and agreements
with other companies in which Santander Brasil's controlling shareholder has an interest, whenever the law or the By-Laws provide
that they must be approved at a shareholders' general meeting; and

&nbsp;&nbsp;&nbsp;&nbsp;· the appraisal of assets to be contributed to increase Santander Brasil's capital stock.

Regarding the election of members of the Board of Directors, the Brazilian Corporate Law sets forth that, when members of the Board of Directors are elected, the following parties have the right to elect one member of Santander Brasil's Board of Directors:

&nbsp;&nbsp;&nbsp;&nbsp;· minority holders of shares in public companies holding a minimum of 15% of the total number of voting shares, or

&nbsp;&nbsp;&nbsp;&nbsp;· holders of preferred shares without voting rights, or with restricted voting rights, representing 10% of the capital stock, or

&nbsp;&nbsp;&nbsp;&nbsp;· holders of common and preferred shares who jointly represent at least 10% of the capital stock, in a separate vote.

Nevertheless, these rights can only be exercised by the holders of shares who maintained their holding for at least three months before the date of the annual shareholders' meeting. The Brazilian Corporate Law also permits a multiple vote procedure to be adopted, upon request by shareholders representing at least 10% of Santander Brasil's voting capital. Pursuant to Resolution No. 70 of March 22, 2022, of the Brazilian Securities and Exchange Commissions (*Comissão de Valores Mobiliários*), or the "CVM," the percentage needed to call for a multiple vote to elect members of the board of directors, in public companies with capital stock exceeding R$100 million, is 5% of the voting capital per request of multiple vote.

The holders of preferred shares are entitled to the following rights according to Santander Brasil's By-Laws:

&nbsp;&nbsp;&nbsp;&nbsp;· dividends and interest on shareholders' own equity in an amount 10% higher than those attributed to common shares, as well as
priority in the distribution;

&nbsp;&nbsp;&nbsp;&nbsp;· participation on equal terms with the common shareholders, in capital increases arising from the capitalization of reserves and income,

&nbsp;&nbsp;&nbsp;&nbsp;· priority in reimbursement of capital, without payment of premium, in the case of liquidation; and

&nbsp;&nbsp;&nbsp;&nbsp;· tag-along rights in the event of a change in Santander Brasil's control, under the same terms and conditions extended to its
controlling shareholders.

Common shares not belonging to the controlling shareholders also give their holders tag-along rights in the event that Santander Brasil's control is transferred on the same terms and conditions as those granted to its controlling shareholders.

The shareholders' general meeting may decide on conversion of the preferred shares into common shares.

The Brazilian Corporate Law sets forth that shares without voting rights or shares with restricted rights, including Santander Brasil's preferred shares, shall be granted unrestricted voting rights if the company ceases to distribute, during three consecutive fiscal years, any fixed or minimum dividend granted to these shares, until the respective distributions are made.

According to Santander Brasil's By-Laws, the dividends that are not claimed by shareholders within three years, from the beginning of their payment, shall be retained by Santander Brasil to its benefit.

Under the Brazilian Corporate Law, any change in the preferences or changes which would have an adverse financial effect on the rights of holders of preferred shares, or any change that results in the creation of a more favored class of preferred shares, must be approved by a resolution at a general shareholders' meeting and will become valid and effective only after approval by a majority of Santander Brasil's preferred shareholders.

Brazilian Corporate Law also sets forth that the following shareholders' rights cannot be repealed or modified by Santander Brasil's By-Laws or decisions made at shareholders' meetings:

&nbsp;&nbsp;&nbsp;&nbsp;· the right to vote at general meetings, in the case of holders of common shares;

&nbsp;&nbsp;&nbsp;&nbsp;· the right to share in the distribution of dividends and interest on shareholders' equity, and to share in the surplus assets
in the event of Santander Brasil's liquidation;

&nbsp;&nbsp;&nbsp;&nbsp;· preemptive rights in subscribing for shares or convertible securities in specific circumstances;

&nbsp;&nbsp;&nbsp;&nbsp;· the right to monitor the management; and

&nbsp;&nbsp;&nbsp;&nbsp;· the right of withdrawal in the circumstances established by law, including Santander Brasil's consolidation, merger and spin-off.

**General Meetings and Voting Rights**

At Santander Brasil's duly convened general meetings, its shareholders are authorized to make resolutions on matters relating to Santander Brasil's activities and to make decisions deemed to be in Santander Brasil's best interests.

Santander Brasil's shareholders are exclusively responsible for approving the financial statements at the annual general meeting, and to decide on the destination of net earnings and the distribution of dividends for the year immediately preceding the meeting. The members of the Board of Directors and Fiscal Council are, as a general rule, elected at annual general meetings unless for an exceptional reason they have to be elected at an extraordinary general meeting.

An extraordinary general meeting may be held at any time, including together with an annual general meeting. Santander Brasil's shareholders in a general meeting are exclusively responsible for approving, among other matters: (i) amendments to Santander Brasil's By-Laws; (ii) election and dismissal of members of Santander Brasil's board of directors; (iii) creation of any reserves of profits, other than the legal reserve; (iv) suspension of the rights of a shareholder that has failed to comply with obligations under the law or Santander Brasil's By-Laws; (v) approval of Santander Brasil's consolidation, merger or spin-off; and (vi) approval of Santander Brasil's dissolution or liquidation, approval of reports prepared by the liquidators and the election of a liquidator and members of the fiscal council to operate during a liquidation.

As a general rule, the Brazilian Corporate Law sets forth that a general meeting can be held if shareholders holding at least 25% of voting shares are present, at the first call, and at the second call if any number of holders of voting shares are present. If the shareholders have been convened to resolve on amendments to the By-Laws, the quorum at the first call must be at least two-thirds of the voting shares and, at the second call, any number of holders of voting shares.

In general, the approval of any matter must occur through votes of shareholders attending a general meeting in person, or through a proxy, corresponding to at least the majority of the common shares represented at the meeting, and abstentions are not taken into account for this calculation. Nevertheless, the affirmative vote of shareholders representing at least one-half of the voting shares is needed for the approval of the following matters, among others: (i) reduction of the mandatory dividend to be distributed to Santander Brasil's shareholders; (ii) changes in Santander Brasil's business purpose; (iii) Santander Brasil's merger, spin-off or consolidation; (iv) Santander Brasil's participation in a corporate group (as defined by the Brazilian Corporate Law); (v) the termination of a state of liquidation; and (vi) Santander Brasil's dissolution.

The CVM may authorize the aforementioned quorum, set forth in the Brazilian Corporate Law, to be reduced in the case of a publicly held company with widely held shares, and where the last three general meetings have been attended by shareholders representing less than half the voting shares.

The Brazilian Corporate Law requires all general meetings to be called by a minimum of three entries in a periodical of mass circulation in São Paulo, where the B3 is located. Our call notices for meetings are currently published in the *Valor Econômico* newspaper. The first call must be published not more than 30 days before the date of the meeting, and the second call not more than eight days in advance. However, in certain circumstances, at the request of any shareholder, the CVM may (i) after consulting Santander Brasil, require the shareholders' meeting to be postponed and held 30 days after the first call; and/or (ii) suspend for up to 15 days the advance notice required for an extraordinary general meeting, to give the shareholder time to understand and analyze the proposals to be voted on at the meeting. The call notices must give full details of the agenda for the meeting (the term "general matters" being prohibited) and the adequate supporting documents must be available to the public on the CVM's website from the date of publication of the first call.

It is usually the responsibility of Santander Brasil's Board of Directors to call a general meeting, provided that such meetings may also be called by the following persons or bodies: (i) any shareholder, when Santander Brasil's directors fail to call a meeting within 60 days of the date required by law or by Santander Brasil's By-Laws; (ii) shareholders representing a minimum of 5% of Santander Brasil's capital stock, if Santander Brasil's managers fail to call a meeting, within eight days, in response to a justified request submitting matters to be discussed; (iii) shareholders representing a minimum of 5% of Santander Brasil's capital stock, if Santander Brasil's Board of Directors fails to call a meeting intended to install a Fiscal Council, within eight days of the request being made; and (iv) the Fiscal Council (if already installed), if Santander Brasil's Board of Directors fails to call the annual general meeting; and (v) the Fiscal Council (if already installed), whenever there are serious or urgent reasons.

Santander Brasil's shareholders' meetings are held at its headquarters at Avenida Presidente Juscelino Kubitschek, 2041, Suite 281, Block A, Condomínio WTORRE JK, Vila Nova Conceição, 04543-011, in the city of São Paulo, state of São Paulo, Federative Republic of Brazil. The Brazilian Corporate Law allows Santander Brasil's shareholders to hold meetings outside its headquarters in an event of force majeure, provided that the meetings are held in the city of São Paulo and the relevant notice contains a clear indication of the place where the meeting will be held.

**Changes in Capital**

Under Brazilian law, the authority to increase share capital rests with the general shareholder's meeting. However, Santander Brasil's general shareholder's meeting may delegate to the board of directors the authority to approve or execute capital increases. Santander Brasil's By-laws are fully aligned with Brazilian law, and do not establish any different conditions for share capital increases. Capital increases and other changes of the By-laws are subject to approval by the Brazilian Central Bank.

As of December 31, 2025, the board of directors was authorized by the general shareholders' meeting to approve or execute capital increases, without need to change the By-laws, up to the total amount of 9,090,909,090 common or preferred shares, with no relation to the existing ratio between shares of each class, subject to the legal limit applicable to preferred shares.

**Dividends**

Santander Brasil's board of directors currently recommends to its shareholders a 50% distribution of Santander Brasil's yearly adjusted net income as dividends and/or interest attributable to shareholders' equity. Santander Brasil's future dividend policy and the amount of future dividends and/or interest attributable to shareholders' equity Santander Brasil decide to recommend to its shareholders for approval will depend on a number of factors, including, but not limited to, its cash flow, financial condition (including capital position), investment plans, prospects, legal requirements, economic climate, regulatory provisions and such other factors as Santander Brasil may deem relevant at the time. For additional information, please refer to "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividend Policy" of the Annual Report on Form 20-F.

**Preemptive Rights**

Santander Brasil's shareholders have preemptive rights to subscribe for shares in any capital increase, in proportion to their shareholding at the time of the increase. Shareholders also have preemptive rights in any offer of Santander Brasil's shares or subscription warrants. A period of not less than 30 days from the publication of the notice to shareholders of the capital increase is allowed for the exercise of preemptive rights, and these rights are transferable.

However, according to the Brazilian Corporate Law and Santander Brasil's By-Laws, Santander Brasil shareholders do not have preemptive rights in cases of granting or exercise of any share call options (provided the share call option is granted by Santander Brasil in accordance with its By-Laws). In addition, Santander Brasil's Board of Directors may exclude the preemptive right of Santander Brasil's shareholders or reduce the exercise period, in the issuance of shares and subscription warrants whose placement is made through sale on stock exchange or public subscription, or share exchange, in a public offering of control acquisition.

**Redemption**

According to the Brazilian Corporate Law, Santander Brasil may redeem its shares by means of a resolution passed at a general meeting by votes representing at least 50% of the shares affected by the redemption. Shares may be redeemed out of retained profits, revenues reserves or capital reserves. If not all of the shares are to be redeemed, a lottery ballot shall be held. If custody shares are selected in the ballot and the custody agreement does not provide for the situation, the financial institution must specify the proportion of shares to be redeemed.

**Registration and Transfers**

The Santander Brasil shares are registered in book-entry form in the B3 system. Santander Brasil also maintains a registry of shareholders.

Under Brazilian law and regulations, transfers of shares quoted on a stock exchange are normally made through the facilities of an independent clearing house, a division of the B3, which handles the multilateral settlement of both financial obligations and transactions involving securities. According to the regulations of the B3, financial settlement is carried out through the system of transfer of funds of the Brazilian Central Bank and the transactions involving the sale and purchase of shares are settled through the B3 custody system.

**Liquidation Rights**

Upon a liquidation of Santander Brasil, its shareholders are entitled to receive pro-rata any assets remaining after the payment of Santander Brasil's debts, taxes and expenses of the liquidation. Holders of preferred shares shall be entitled to receive reimbursement of the amount paid before any amount is distributed to the holders of common shares.

**Disposal of Control**

Santander Brasil's By-Laws state that disposal of control in Santander Brasil, either in a single transaction or in a series of transactions, must be subject to a condition precedent or a resolutory condition that the acquirer makes a public offer to acquire all the shares held by Santander Brasil's other shareholders, both common and preferred. This is also compliant with the conditions and deadlines required by applicable law, ensuring that minority shareholders receive equal treatment with respect to the controlling shareholder in the disposal of control.

This public offer is also required (i) in cases where there is assignment for consideration of rights to subscribe for shares that may result in the disposal of the company's control; and (ii) in case of disposal of control of a company that holds the controlling power over Santander Brasil.

The disposal of control will also be subject to the prior authorization of the Brazilian Central Bank, pursuant to the terms and conditions of Central Bank Resolution No. 4,970/22. For additional information, please refer to "Item 4. Information on the Company—4B. Business Overview—Regulation and Supervision" of the Annual Report on Form 20-F.

**Restrictions on Voting Rights or Free Transfer of Santander Brasil's Shares**

There are no legal restrictions or restrictions in Santander Brasil's By-Laws on the exercise of voting rights except for those resulting from the failure to comply with applicable regulations.

There are no restrictions on the free transfer of shares, except for the prior authorization required by the Brazilian Central Bank in case the transfer results in a change of control. In addition, a qualified ownership interest, which represents at least 10% of the total corporate capital of Santander Brasil, has to be reported to the Brazilian Central Bank and is subject to a review process by the regulator after the transaction is completed.

The transferability of the shares is not restricted by Santander Brasil's By-laws or in any other manner other than by the application of legal and regulatory provisions. Likewise, there are no restrictions in Santander Brasil's By-Laws on the exercise of voting rights (except where an acquisition has been made in breach of legal or regulatory provisions).

**Significant Shareholders**

As of February 27, 2026, Santander Spain directly and indirectly through its subsidiaries, Grupo Empresarial Santander, S.L. and Sterrebeeck B.V., owned approximately 89.53 % of Santander Brasil's total capital stock. For additional information, please refer to "Item 7. Major Shareholders and Related Party Transactions—7A. Major Shareholders" of the Annual Report on Form 20-F.

CVM Resolution No. 44, dated August 23, 2021, sets forth that (i) any direct or indirect controlling shareholders, (ii) any shareholders entitled to elect members of the board of directors and fiscal council, as well as (iii) any person or group of persons acting jointly with the aforementioned persons or representing the same interest, that carries out relevant transactions (that is, transactions whereby the direct or indirect holding of the aforementioned persons surpasses, upwards or downwards the thresholds of 5%, 10%, 15%, and so on successively, of Santander Brasil's shares of a certain class and type) must disclose to Santander Brasil information on their trades, which will be sent to the CVM. For more information, please refer to "Item 10. Additional Information—B. By-Laws—Disclosure of Information About Our Shareholders with Relevant Interest" of the Annual Report on Form 20-F.

The acquisition of a significant stake in Santander Brasil may also require the authorization of other regulators with supervisory powers over Santander Brasil's and its subsidiaries' activities and shares listings or other actions in connection with those regulators or subsidiaries.

**<u>Description of Units</u>**

The following description of Banco Santander (Brasil) S.A. ("Santander Brasil")'s units, each representing one common share and one preferred share (the "Units"), is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to Santander Brasil's By-laws, an English translation of which is incorporated by reference as an exhibit to the Annual Report on Form 20-F, as well as on the legislation and regulations applicable to companies and the Brazilian capital market currently in effect. Santander Brasil encourages you to read the By-Laws for additional information. Capitalized terms used and not defined hereinafter shall have the meanings ascribed to them throughout the Annual Report on Form 20-F.

The Units are share deposit certificates, each representing one common share and one preferred share, all of them free and unencumbered. The shares represented by the Units shall be registered in a trust account linked to the Units, and their ownership can only be transferred by means of transfer of the corresponding Units, upon written instructions from the holder. Earnings from the Units and the amount received in the case of redemption or repayment shall only be paid to the holder of the Units registered in the books of the custodian.

None of the shares underlying the Units, the earnings thereon or the corresponding redemption or repayment amounts may be pledged, encumbered or in any other way given in guarantee by the holder of the Units, nor may they be subject to attachment (*penhora*), seizure (*arresto*), impounding (*sequestro*), search and apprehension (*busca e apreensão*), or to any other lien or encumbrance.

The Units are held by Santander Brasil (except units that underlie the ADSs which are held by its affiliate, Santander Caceis Brasil Distribuidora de Títulos e Valores Mobiliários S.A.), as the custodian, in book-entry form and in an account opened in the holder's name. The transfer of ownership is effected by debiting the seller's Unit custody account and crediting the buyer's Unit custody account according to a written transfer order issued by the seller or a court authorization or transfer order delivered to the custodian, all of which are retained by the custodian. Dividends, interest on shareholders' equity and/or cash bonuses shall be paid to the custodian and the custodian shall then transfer the amount to the custody agents for payment to the Unit holders. The pledge, usufruct, right of succession, fiduciary transfer in guarantee and any other conditions, onus or encumbrances on the Units must be registered in the custodian's records, as well as noted in the corresponding statement of account of Units.

The custodian shall provide Unit holders with a statement of account at the end of each month in which there is movement and, when there is no movement, at least once a year. The statement shall show the date and place of issue, the name and details of the holder of the Unit account, an indication that it is a statement of Unit account, details of the shares deposited, a statement that the shares deposited, their earnings and any amounts received in the event of redemption or repayment shall only be paid to the holder of the Unit account or to the holder's order in writing, Santander Brasil's charge for the deposit, if any, and the addresses where Unit holders may obtain assistance.

Upon a written order issued by the holder of the Unit account to a broker authorized by the stock exchange where the Units are traded, the custodian shall block the corresponding Units and transfer them to the buyer upon receipt of a confirmation of the sale from the stock exchange.

The Unit holder shall have the right, at any time, to instruct a broker to cancel Units and transfer the underlying shares. The broker must request to Santander Brasil, as the agent, to transfer the Units to the share deposit accounts held by the custodian in the holder's name. The Unit holder shall bear any transfer and cancellation costs involved. Similarly, the holder may instruct a broker to assemble Units by transferring the number of shares that jointly represent a Unit, which shall be registered by the custodian in a trust account linked to the Units.

The right to cancel Units may be suspended in the event of a public offering for distribution of Units, either in the domestic or the international market, in which case the suspension may not last longer than 180 days. Units subject to any lien or encumbrance may not be cancelled.

The following rules apply to the exercise of the rights granted to the shares represented by Units:

&nbsp;&nbsp;&nbsp;&nbsp;· Dividends and share redemption or repayment amounts delivered to Santander Brasil, as depository of the shares, shall be paid by Santander
Brasil to the Unit holder;

&nbsp;&nbsp;&nbsp;&nbsp;· Only the Unit holder shall have the right to attend Santander Brasil's general meetings and to exercise all the prerogatives
conferred on Santander Brasil's shareholders by the shares represented by the Units;

&nbsp;&nbsp;&nbsp;&nbsp;· In the event of a stock split, cancellation or reverse stock split or new issuances of shares by Santander Brasil while the Units
are in existence, the following rules will be observed:

(1) In the event there is a change in the number of shares represented by Units as a result of a reverse stock split or cancellation of shares, Santander Brasil will debit the number of cancelled shares from each Unit holder's account and proceed with the automatic cancellation of Units, observing the ratio of one common share and one preferred share issued by Santander Brasil to each Unit. Santander Brasil will deliver to the shareholders the shares which are insufficient to constitute a Unit in the form of shares, rather than Units; and

(2) In the event there is a change in the number of shares represented by the Units as a result of a stock split or new issuances of shares, the custodian will register the deposit of the new shares and issue new Units, registering them in the accounts of their respective holders, so as to reflect the new number of shares held by unit holders. In this way, the accounts will maintain a ratio of one common share and one preferred share issued by Santander Brasil and represented by Units, and the custodian will deliver to holders the shares which are insufficient to constitute a Unit in the form of shares rather than Units;

In the event of a capital increase, by means of the issuance of shares that may be converted into new Units, Unit holders may exercise the preemptive rights belonging to the shares represented by their Units. Santander Brasil shall create new Units in the register of book-entry Units and credit them to their holders so as to reflect the new number of common and preferred shares issued by Santander Brasil, subject to the current proportion of ordinary and preferred shares to constitute the Units. Shares that are too few to constitute a Unit shall be delivered to the shareholders as shares, rather than Units. There shall be no automatic credit of Units in the event of the exercise of preemptive rights in the issue of securities other than shares.

Unit holders will be entitled to receive any shares issued as a result of Santander Brasil's spin-off, consolidation or merger.

**DESCRIPTION OF THE REGISTRANT'S SECURITIES<br> REGISTERED PURSUANT TO SECTION 12 OF THE<br> SECURITIES EXCHANGE ACT OF 1934**

**<u>Description of American Depositary Shares</u>**

The following description of Banco Santander (Brasil) S.A. ("Santander Brasil")'s American depositary shares (the "ADSs") is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to the deposit agreement (the "Deposit Agreement") dated October 20, 2015 among Santander Brasil, The Bank of New York Mellon (the "Depositary"), as depositary, and the holders from time to time of American depositary shares ("ADSs") issued thereunder, including the form of American depositary receipts ("ADR"). For more complete information, you should read the entire Deposit Agreement and the form of ADR. The form of Deposit Agreement (including the form of ADR) is incorporated by reference as an exhibit to the Annual Report on Form 20-F. Capitalized terms shall have the meaning stated herein or the meaning stated in the Deposit Agreement.

**American Depositary Shares / American Depositary Receipts**

The ADSs have been listed and traded on the New York Stock Exchange since October 7, 2009. The Depositary will register and deliver ADSs. Each ADS represents one (1) unit (or a right to receive one (1) unit) deposited with Banco Santander (Brasil) S.A., as custodian for the Depositary in Brazil. Each ADS will also represent any other securities, cash or other property which may be held by the Depositary. The Depositary's office at which the ADSs are administered is located at 101 Barclay Street, New York, New York 10286. The Bank of New York Mellon's principal executive office is located at 225 Liberty Street, New York, New York 10286.

You may hold ADSs either (A) directly (i) by having an ADR, which is a certificate evidencing a specific number of ADSs, registered in your name, or (ii) by having uncertificated ADSs registered in your name, or (B) indirectly by holding a security entitlement in ADSs through your broker or other financial institution that is a direct or indirect participant in The Depository Trust Company, also called DTC. If you hold ADSs directly, you are a registered ADS holder, also referred to as an ADS holder. This description assumes you are an ADS holder. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADS holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

Registered holders of uncertificated ADSs will receive statements from the Depositary confirming their holdings.

As an ADS holder, Santander Brasil will not treat you as one of its shareholders and you will not have shareholder rights. Brazilian law governs shareholder rights. The Depositary is the holder of the units underlying your ADSs. As a registered holder of ADSs, you have ADS holder rights. The Deposit Agreement among Santander Brasil, the Depositary, ADS holders and all other persons indirectly or beneficially holding ADSs sets out ADS holder rights as well as the rights and obligations of the Depositary. New York law governs the Deposit Agreement and the ADSs.

**Dividends and Other Distributions**

**How will you receive dividends and other distributions on the units?**

The Depositary has agreed to pay or distribute to ADS holders the cash dividends or other distributions it or the custodian receives on units or other deposited securities, upon payment or deduction of its fees and expenses. You will receive these distributions in proportion to the number of units your ADSs represent. Before making a distribution, any withholding taxes, or other governmental charges that must be paid will be deducted.

*Cash*. The Depositary will convert any cash dividend or other cash distribution Santander Brasil pays on the units into U.S. dollars if it can do so on a reasonable basis and can transfer the U.S. dollars to the United States. If that is not possible or if any government approval is needed and cannot be obtained, the Deposit Agreement allows the Depositary to distribute the foreign currency only to those ADS holders who request such distribution and to whom it is possible to do so. It will hold the foreign currency it cannot convert for the account of the ADS holders who have not been paid. It will not invest the foreign currency and it will not be liable for any interest.

The Depositary will distribute only whole U.S. dollars and cents and will round fractional cents to the nearest whole cent. *If the exchange rates fluctuate during a time when the Depositary cannot convert the foreign currency, you may lose some of the value of the distribution.*

*Units*. The Depositary may distribute additional ADSs representing any units Santander Brasil distributes as a dividend or free distribution. The Depositary will only distribute whole ADSs. It will sell units which would require it to deliver a fraction of an ADS (or ADSs representing those units) and distribute the net proceeds in the same way as it does with cash. If the Depositary does not distribute additional ADSs, the outstanding ADSs will also represent the new units. The Depositary may sell a portion of the distributed units (or ADSs representing those units) sufficient to pay its fees and expenses in connection with that distribution.

*Rights to purchase additional units*. If Santander Brasil offers holders of its securities any rights to subscribe for additional units or any other rights, the Depositary may (i) exercise those rights on behalf of ADS holders, (ii) distribute those rights to ADS holders or (iii) sell those rights and distribute the net proceeds to ADS holders, in each case after deduction or upon payment of its fees and expenses. To the extent the Depositary does not do any of those things, it will allow the rights to lapse. *In that case, you will receive no value for them*. The Depositary will exercise or distribute rights only if Santander Brasil asks it to and provide satisfactory assurances to the Depositary that it is legal to do so. If the Depositary will exercise rights, it will purchase the securities to which the rights relate and distribute those securities or, in the case of units, new ADSs representing the new units, to subscribing ADS holders, but only if ADS holders have paid the exercise price to the Depositary. U.S. securities laws may restrict the ability of the Depositary to distribute rights or ADSs or other securities issued on exercise of rights to all or certain ADS holders, and the securities distributed may be subject to restrictions on transfer.

*Other distributions*. The Depositary will send to ADS holders anything else Santander Brasil distributes on deposited securities by any means it thinks is legal, fair and practical. If it cannot make the distribution in that way, the Depositary has a choice. It may decide to sell what Santander Brasil distributed and distribute the net proceeds, in the same way as it does with cash. Or, it may decide to hold what Santander Brasil distributed, in which case ADSs will also represent the newly distributed property. However, the Depositary is not required to distribute any securities (other than ADSs) to ADS holders unless it receives satisfactory evidence from Santander Brasil that it is legal to make that distribution. The Depositary may sell a portion of the distributed securities or property sufficient to pay its fees and expenses in connection with that distribution. U.S. securities laws may restrict the ability of the Depositary to distribute securities to all or certain ADS holders, and the securities distributed may be subject to restrictions on transfer.

The Depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. Santander Brasil has no obligation to register ADSs, units, rights or other securities under the Securities Act. Santander Brasil also has no obligation to take any other action to permit the distribution of ADSs, units, rights or anything else to ADS holders. *This means that you may not receive the distributions Santander Brasil makes on its units or any value for them if it is illegal or impractical for Santander Brasil to make them available to you.*

**Deposit, Withdrawal and Cancellation**

**How are ADSs issued?**

The Depositary will deliver ADSs if you or your broker deposits units or evidence of rights to receive units with the custodian with any appropriate documentation that the custodian requires. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the Depositary will register the appropriate number of ADSs in the names you request and will deliver the ADSs to or upon the order of the person or persons that made the deposit.

**How can ADS holders withdraw the deposited securities?**

You may surrender your ADSs for the purpose of withdrawal at the Depositary's office. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the Depositary will deliver the units and any other deposited securities underlying the ADSs to the ADS holder or a person the ADS holder designates at the office of the custodian. Or, at your request, risk and expense, the Depositary will deliver the deposited securities at its office or other requested locations. The Depositary may charge you a fee and its expenses for instructing the custodian regarding delivery of deposited securities.

**How do ADS holders interchange between certificated ADSs and uncertificated ADSs?**

You may surrender your ADR to the Depositary for the purpose of exchanging your ADR for uncertificated ADSs. The Depositary will cancel that ADR and will send to the ADS holder a statement confirming that the ADS holder is the registered holder of uncertificated ADSs. Alternatively, upon receipt by the Depositary of a proper instruction from a registered holder of uncertificated ADSs requesting the exchange of uncertificated ADSs for certificated ADSs, the Depositary will execute and deliver to the ADS holder an ADR evidencing those ADSs.

**Voting Rights**

**How do you vote?**

ADS holders may instruct the Depositary how to vote the number of deposited units their ADSs represent. If Santander Brasil requests the Depositary to solicit your voting instructions (and Santander Brasil is not required to do so), the Depositary will notify you of a shareholders' meeting and send or make voting materials available to you. Those materials will describe the matters to be voted on and explain how ADS holders may instruct the Depositary how to vote. For instructions to be valid, they must reach the Depositary by a date set by the Depositary. The Depositary will try, as far as practical, subject to any applicable provision of Brazilian law and of Santander Brasil's By-Laws or similar documents, to vote or to have its agents vote the units, shares or other deposited securities as instructed by ADS holders. If Santander Brasil does not request the Depositary to solicit your voting instructions, you can still send voting instructions, and, in that case, the Depositary may try to vote as you instruct, but it is not required to do so.

Except by instructing the Depositary as described above, you will not be able to exercise voting rights unless you surrender your ADSs and withdraw the units. However, you may not know about the meeting enough in advance to withdraw the units. In any event, the Depositary will not exercise any discretion in voting deposited securities and it will only vote or attempt to vote as instructed or as described in the following sentence. If Santander Brasil asked the Depositary to solicit your instructions at least 30 days before the meeting date but the Depositary does not receive voting instructions from you by the specified date, it will consider you to have authorized and directed it to give a discretionary proxy to a person designated by Santander Brasil to vote the number of deposited securities represented by your ADSs. The Depositary will give a discretionary proxy in those circumstances to vote on all questions to be voted upon unless Santander Brasil notifies the Depositary that:

&nbsp;&nbsp;&nbsp;&nbsp;· Santander Brasil does not wish to receive a discretionary proxy;

&nbsp;&nbsp;&nbsp;&nbsp;· there is substantial opposition from Santander Brasil's shareholders to the manner in which such deposited securities would
be voted with respect to the particular question; or

&nbsp;&nbsp;&nbsp;&nbsp;· the particular question would have a material and adverse impact on the rights of Santander Brasil's shareholders.

Santander Brasil cannot assure you that you will receive the voting materials in time to ensure that you can instruct the Depositary to vote your units. In addition, the Depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your voting rights and there may be nothing you can do if your units are not voted as you requested.

If Santander Brasil requests the Depositary to act, Santander Brasil agrees to give the Depositary notice of any such meeting and details concerning the matters to be voted upon as far in advance of the meeting date as practicable.

**Record Dates**

Whenever (i) a cash dividend, cash distribution or any other distribution is made on deposited securities or rights to purchase units or other securities are issued with respect to deposited securities or the Depositary receives notice that a distribution or issuance of that kind will be made, (ii) the Depositary receives notice that a meeting of holders of units or common or preferred shares will be held in respect of which Santander Brasil has requested the Depositary to send a notice, (iii) the Depositary will assess a fee or charge against ADS holders, (iv) the Depositary causes a change in the number of units that are represented by each ADS, or (v) the Depositary otherwise finds it necessary or convenient, in each case, the Depositary will fix a corresponding record date for ADS holders, which shall be the same as, or as near as practicable to, any corresponding record date set by Santander Brasil with respect to units or common or preferred shares.

**Payment of Taxes**

You will be responsible for any taxes or other governmental charges payable on your ADSs or on the deposited securities represented by any of your ADSs. The Depositary may refuse to register any transfer of your ADSs or allow you to withdraw the deposited securities represented by your ADSs until such taxes or other charges are paid. It may apply payments owed to you or sell deposited securities represented by your ADSs to pay any taxes owed and you will remain liable for any deficiency. If the Depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to reflect the sale and pay to ADS holders any proceeds, or send to ADS holders any property, remaining after it has paid the taxes.

**Tender and Exchange Offers; Redemption, Replacement or Cancellation of Deposited Securities**

The Depositary will not tender deposited securities in any voluntary tender or exchange offer unless instructed to do so by an ADS holder surrendering ADSs and subject to any conditions or procedures the Depositary may establish.

If deposited securities are redeemed for cash in a transaction that is mandatory for the Depositary as a holder of deposited securities, the Depositary will call for surrender of a corresponding number of ADSs on a pro rata basis and distribute the net redemption money to the holders of called ADSs upon surrender of those ADSs.

If there is any change in the deposited securities such as a sub-division, combination or other reclassification, or any merger, consolidation, recapitalization or reorganization affecting the issuer of deposited securities in which the Depositary receives new securities in exchange for or in lieu of the old deposited securities, the Depositary will hold those replacement securities as deposited securities under the Deposit Agreement. However, if the Depositary decides it would not be lawful and to hold the replacement securities because those securities could not be distributed to ADS holders or for any other reason, the Depositary may instead sell the replacement securities and distribute the net proceeds upon surrender of the ADSs.

If there is a replacement of the deposited securities and the Depositary will continue to hold the replacement securities, the Depositary may distribute new ADSs representing the new deposited securities or ask you to surrender your outstanding ADRs in exchange for new ADRs identifying the new deposited securities.

If there are no deposited securities underlying ADSs, including if the deposited securities are cancelled, or if the deposited securities underlying ADSs have become apparently worthless, the Depositary may call for surrender or of those ADSs or cancel those ADSs upon notice to the ADS holders.

**Amendment and Termination**

**How may the Deposit Agreement be amended?**

Santander Brasil may agree with the Depositary to amend the Deposit Agreement and the ADRs without your consent for any reason. If an amendment adds or increases fees or charges, except for taxes and other governmental charges or expenses of the Depositary for registration fees, facsimile costs, delivery charges or similar items, or prejudices a substantial right of ADS holders, it will not become effective for outstanding ADSs until 30 days after the Depositary notifies ADS holders of the amendment. Upon an amendment which changes the number of units represented by each ADS, the Depositary may call for the surrender and/or exchange of ADRs to effect the change. *At the time an amendment becomes effective, you are considered, by continuing to hold your ADSs, to agree to the amendment and to be bound by the ADRs and the Deposit Agreement as amended.*

**How may the Deposit Agreement be terminated?**

The Depositary will initiate termination of the Deposit Agreement if Santander Brasil instructs it to do so. The Depositary may initiate termination of the Deposit Agreement if:

&nbsp;&nbsp;&nbsp;&nbsp;· 90 days have passed since the Depositary told Santander Brasil it wants to resign but a successor Depositary has not been appointed
and accepted its appointment;

&nbsp;&nbsp;&nbsp;&nbsp;· Santander Brasil delists its units from an exchange on which they were listed and does not list the units on another exchange;

&nbsp;&nbsp;&nbsp;&nbsp;· Santander Brasil enters insolvency proceedings or information becomes publicly available indicating that unsecured claims against
Santander Brasil are not expected to be paid;

&nbsp;&nbsp;&nbsp;&nbsp;· all or substantially all the value of the deposited securities has been distributed either in cash or in the form of securities;

&nbsp;&nbsp;&nbsp;&nbsp;· there are no deposited securities underlying the ADSs or the underlying deposited securities have become apparently worthless; or

&nbsp;&nbsp;&nbsp;&nbsp;· there has been a replacement of deposited securities.

If the Deposit Agreement is terminated, the Depositary will notify ADS holders at least 120 days before the termination date. At any time after the termination date, the Depositary may sell the deposited securities. After that, the Depositary will hold the money it received on the sale, as well as any other cash it is holding under the Deposit Agreement, unsegregated and without liability for interest, for the *pro rata* benefit of the ADS holders that have not surrendered their ADSs. Normally, the Depositary will sell as soon as practicable after the termination date.

After the termination date and before the Depositary sells, ADS holders can still surrender their ADSs and receive delivery of deposited securities, except that the Depositary may refuse to accept a surrender for the purpose of withdrawing deposited securities if it would interfere with the selling process. The Depositary may refuse to accept a surrender for the purpose of withdrawing sale proceeds until all the deposited securities have been sold. The Depositary will continue to collect distributions on deposited securities, *but*, after the termination date, the Depositary is not required to register any transfer of ADSs or distribute any dividends or other distributions on deposited securities to the ADSs holder (until they surrender their ADSs) or give any notices or perform any other duties under the Deposit Agreement except as described in this paragraph.

**Limitations on Obligations and Liability**

**Limits on Santander Brasil's Obligations and the Obligations of the Depositary; Limits on Liability to Holders of ADSs**

The Deposit Agreement expressly limits Santander Brasil's obligations and the obligations of the Depositary. It also limits Santander Brasil's liability and the liability of the Depositary. Santander Brasil and the Depositary:

&nbsp;&nbsp;&nbsp;&nbsp;· are only obligated to take the actions specifically set forth in the Deposit Agreement without negligence or bad faith;

&nbsp;&nbsp;&nbsp;&nbsp;· are not liable if Santander Brasil is or it is prevented or delayed by law or circumstances beyond Santander Brasil's or its
control from performing Santander Brasil's or its obligations under the Deposit Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;· are not liable if Santander Brasil or it exercises discretion permitted under the Deposit Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;· are not liable for the inability of any holder of ADSs to benefit from any distribution on deposited securities that is not made available
to holders of ADSs under the terms of the Deposit Agreement, or for any special, consequential or punitive damages for any breach of the
terms of the Deposit Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;· have no obligation to become involved in a lawsuit or other proceeding related to the ADSs or the Deposit Agreement on your behalf
or on behalf of any other person; and

&nbsp;&nbsp;&nbsp;&nbsp;· may rely upon any documents Santander Brasil believes or it believes in good faith to be genuine and to have been signed or presented
by the proper person.

In the Deposit Agreement, Santander Brasil and the Depositary agree to indemnify each other under certain circumstances.

**Requirements for Depositary Actions**

Before the Depositary will deliver or register a transfer of ADSs, make a distribution on ADSs, or permit withdrawal of units, the Depositary may require:

&nbsp;&nbsp;&nbsp;&nbsp;· payment of stock transfer or other taxes or other governmental charges and transfer or registration fees charged by third parties
for the transfer of any units or other deposited securities;

&nbsp;&nbsp;&nbsp;&nbsp;· satisfactory proof of the identity and genuineness of any signature or other information it deems necessary; and

&nbsp;&nbsp;&nbsp;&nbsp;· compliance with regulations it may establish, from time to time, consistent with the Deposit Agreement, including presentation of
transfer documents.

The Depositary may refuse to deliver ADSs or register transfers of ADSs when the transfer books of the Depositary or Santander Brasil's transfer books are closed or at any time if the Depositary or Santander Brasil thinks it advisable to do so.

**Your Right to Receive the Units Underlying your ADSs**

ADS holders have the right to cancel their ADSs and withdraw the underlying units at any time except:

&nbsp;&nbsp;&nbsp;&nbsp;· when temporary delays arise because: (i) the Depositary has closed its transfer books or Santander Brasil has closed its transfer
books; (ii) the transfer of units is blocked to permit voting at a shareholders' meeting; or (iii) Santander Brasil is paying a
dividend on its units;

&nbsp;&nbsp;&nbsp;&nbsp;· when you owe money to pay fees, taxes and similar charges; or

&nbsp;&nbsp;&nbsp;&nbsp;· when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to
the withdrawal of units or other deposited securities.

This right of withdrawal may not be limited by any other provision of the Deposit Agreement.

**Pre-release of ADSs**

The Deposit Agreement permits the Depositary to deliver ADSs before deposit of the underlying units. This is called a pre-release of the ADSs. The Depositary may also deliver units upon the surrender of pre-released ADSs (even if the ADSs are surrendered before the pre-release transaction has been closed out). A pre-release is closed out as soon as the underlying units are delivered to the Depositary. The Depositary may receive ADSs instead of units to close out a pre-release. The Depositary may pre-release ADSs only under the following conditions: (i) before or at the time of the pre-release, the person to whom the pre-release is being made represents to the Depositary in writing that it or its customer (a) owns the units or ADSs to be deposited, (b) assigns all rights, title and interest in the units to the Depositary and (c) will not take any action with respect to such units or ADSs inconsistent with beneficial ownership; (ii) the pre-release is fully collateralized with cash or other collateral that the Depositary considers appropriate; and (iii) the Depositary must be able to close out the pre-release on not more than five business days' notice. In addition, the Depositary will limit the number of ADSs that may be outstanding at any time as a result of pre-release, although the Depositary may disregard the limit from time to time, if it thinks it is appropriate to do so.

**Direct Registration System**

In the Deposit Agreement, all parties to the Deposit Agreement acknowledge that the Direct Registration System, also referred to as DRS, and Profile Modification System, also referred to as Profile, will apply to the ADSs. DRS is a system administered by DTC that facilitates interchange between registered holding of uncertificated ADSs and holding of security entitlements in ADSs through DTC and a DTC participant. Profile is feature of DRS that allows a DTC participant, claiming to act on behalf of a registered holder of uncertificated ADSs, to direct the Depositary to register a transfer of those ADSs to DTC or its nominee and to deliver those ADSs to the DTC account of that DTC participant without receipt by the Depositary of prior authorization from the ADS holder to register that transfer.

In connection with and in accordance with the arrangements and procedures relating to DRS/Profile, the parties to the Deposit Agreement understand that the Depositary will not determine whether the DTC participant that is claiming to be acting on behalf of an ADS holder in requesting registration of transfer and delivery as described in the paragraph above has the actual authority to act on behalf of the ADS holder (notwithstanding any requirements under the Uniform Commercial Code). In the Deposit Agreement, the parties agree that the Depositary's reliance on and compliance with instructions received by the Depositary through the DRS/Profile system and in accordance with the Deposit Agreement will not constitute negligence or bad faith on the part of the Depositary.

**Shareholder Communications; Inspection of Register of Holders of ADSs**

The Depositary will make available for your inspection at its office all communications that it receives from Santander Brasil as a holder of deposited securities that Santander Brasil makes generally available to holders of deposited securities. The Depositary will send you copies of those communications or otherwise make those communications available to you if Santander Brasil asks it to. You have a right to inspect the register of holders of ADSs, but not for the purpose of contacting those holders about a matter unrelated to Santander Brasil's business or the ADSs.

**Disclosure of Interests**

When required in order to comply with applicable laws and regulations or Santander Brasil's By-Laws, Santander Brasil may from time to time request each ADS holder to provide to the Depositary, and each ADS holder agrees to provide and consents to the disclosure of, information relating to: (a) the capacity in which it holds ADSs, (b) the identity of any holders or other persons or entities then or previously interested in those ADSs and the nature of those interests, and (c) any other matter where disclosure of such matter is required for that compliance.

---

The Depositary may charge its fees and expenses to the ADS holders, any party depositing or withdrawing units or any party surrendering ADSs or to whom ADSs are issued (including, without limitation, any issuance pursuant to a stock dividend or stock split declared by Santander Brasil or an exchange of stock regarding any units deposited or deemed to be deposited or any distributions of ADSs in connection with a dividend or otherwise), or by owners of ADSs, as applicable, pursuant to the terms of the Deposit Agreement. Fees will only be due by an investor to the extent such investor is depositor of units or the holder of ADSs.

The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing units or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may collect its annual fee for Depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The Depositary may collect any of its fees by deduction from any cash distribution payable (or by selling a portion of securities or other property distributable) to ADS holders that are obligated to pay those fees. The Depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

From time to time, the Depositary may make payments to Santander Brasil to reimburse Santander Brasil for costs and expenses generally arising out of establishment and maintenance of the ADS program, waive fees and expenses for services provided to Santander Brasil by the Depositary or share revenue from the fees collected from ADS holders. In performing its duties under the Deposit Agreement, the Depositary may use brokers, dealers, foreign currency dealers or other service providers that are owned by or affiliated with the Depositary and that may earn or share fees, spreads or commissions.

The Depositary may convert currency itself or through any of its affiliates and, in those cases, acts as principal for its own account and not as agent, advisor, broker or fiduciary on behalf of any other person and earns revenue, including, without limitation, transaction spreads, that it will retain for its own account. The revenue is based on, among other things, the difference between the exchange rate assigned to the currency conversion made under the Deposit Agreement and the rate that the Depositary or its affiliate receives when buying or selling foreign currency for its own account. The Depositary makes no representation that the exchange rate used or obtained in any currency conversion under the Deposit Agreement will be the most favorable rate that could be obtained at the time or that the method by which that rate will be determined will be the most favorable to ADS holders, subject to the Depositary's obligations under the Deposit Agreement. The methodology used to determine exchange rates used in currency conversions is available upon request.
