**Relationship with the independent auditors**

The Company has a policy with requirements for contractual risk analysis which defines that the Board of Directors must evaluate the transparency, objectivity, governance aspects and the compromising of the independence of the contract, thus ensuring conformity between the parties involved. Additionally, it has an Audit Committee whose responsibilities include both providing opinions and recommendations on the audit service provider and evaluating the effectiveness of the independent and internal audits, including compliance evaluation of legal provisions and regulations applicable to Inter, as well as internal policies and codes.

Furthermore, Inter&Co, Inc. confirms that KPMG Auditores Independentes Ltda. has procedures, policies, and controls in place to ensure its independence, which include an evaluation of the work provided, covering any service other than the independent audit of Company's financial information. This evaluation is based on the applicable regulations and accepted principles that preserve the auditor's independence. The acceptance and performance of non-audit professional services on the financial Information by its independent auditors during the period ended as of September 30, 2025 did not affect the independence and objectivity in the conduct of the audit work performed at Inter & Co, Inc. Information related to independent auditors' fees is made available annually in the reference form.

**Acknowledgment**

We would like to thank our shareholders, customers, and partners for their trust, as well as each of our employees who build our history each day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.Functional and presentation currency**

These unaudited interim condensed consolidated financial statements are presented in Brazilian reais (BRL or R$). The functional currency of the Group companies is shown in note4a. All balances were rounded to the nearest thousand, unless otherwise indicated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.Use of estimates and judgments**

In preparing these unaudited interim condensed consolidated financial statements, management has made judgments, estimates and assumptions that affect the application of the accounting policies of the Group and the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from such estimates. Estimates and assumptions are reviewed on an ongoing basis. Adjustments, if any, related to changes in estimates are recognized prospectively. The significant judgments made by management during the application of the Group's accounting policies and the sources of estimation uncertainty are described below:

Judgments

Information about the judgments made in the application of accounting policies that have the most relevant effects on the amounts recognized in financial projections are included in the following notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Basis for consolidation (see note 4a): whether Inter&Co has de facto control over an investee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Classification of financial assets (see notes 6 and 7): assessment of whether financial assets comply with the sole payment of principal and interest (SPPI test) criteria and the business model in which the assets are managed (amortized cost, fair value through other comprehensive income or fair value through profit or loss).

Estimates

The estimates present a significant risk and may have a material impact on the values of assets and liabilities in the coming years, and the actual results may differ from those previously established. The main items susceptible to impacts due to these estimates are shown below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Classification of financial assets (see notes 6 and 7) - evaluation of the business model in which the assets are held and evaluation of whether the contractual terms of the financial asset relate only to payments of principal and interest (SPPI test).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Impairment test of intangible assets and goodwill (see note 14): for the purposes of impairment testing, each Group entity was considered a cash generating unit ("CGU"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Deferred tax asset (see note 32): the expected realization of the deferred tax asset is based on projected future taxable income and other technical studies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expected credit loss (see notes 12d and 21): the measurement of expected credit loss on assets measured at amortized cost and fair value through other comprehensive income (FVOCI) requires the use of complex quantitative models and assumptions about future economic conditions and credit behavior. Several significant judgments are also needed to apply the accounting requirements for measuring expected credit loss, such as: determining the criteria to evaluate the significant increase in credit risk; selecting quantitative models; and establishing different prospective scenarios and their weighting, and others.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions (see note 21): recognition and measurement of provisions, including the provision for legal proceedings. The main assumptions considered refer to the probability and magnitude of outflows of resources.

**3. New accounting standards recently issued**

New or revised accounting pronouncements adopted in 2025

The following new or revised standards were issued by the IASB and adopted by the Group for the periods covered by these unaudited interim condensed consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Amendment to IAS 21 - The Effects of Changes in Foreign Exchange Rates and Translation of Financial Statements:** The changes require the application of a consistent approach when assessing whether one currency can be exchanged for another, and the amendment clarifies how entities should determine the exchange rate to be used and the disclosures to be provided when a currency is difficult or impossible to exchange. The amendments aim to improve the information an entity provides in its financial statements. This amendment is required for annual financial statements for periods beginning on or after January 1, 2025. Management did not identify any impacts, as there are no currencies in its operations that are difficult or impossible to exchange in the Group's consolidated financial statements.

Other new standards and interpretations issued but not yet effective

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Amendments to IFRS 9 - Financial Instruments and IFRS 7 - Financial Instruments Disclosures:** Issued in May 2024, the amendments and clarifications relate to the derecognition of financial liabilities through electronic systems, assessment of contractual cash flow characteristics in classification (SPPI Test), such as financial assets linked to ESG (Environmental, Social and Governance) and other financial instruments. Additionally, additional disclosures were included regarding equity instruments designated at fair value through other comprehensive income and financial instruments linked to contingent events. The amendments are effective for periods beginning on January 1, 2026. Management is assessing the effects of adopting this amendment for the Group's consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **IFRS 18 - Presentation and Disclosure in Financial Statements:** Issued in April 2024, it replaces IAS 1 and brings additional requirements for financial statements with the aim of enhancing information to shareholders. It defines three categories for income and expenses: operating, investing, and financing, and includes new subtotals.

**6. Financial risk management**

Risk management for the Group includes credit, market, liquidity and operational risks. Risk management activities are carried out by independent and specialized structures, in accordance with previously defined policies and strategies. In general, the activities and processes seek to identify, measure, and control the financial and non-financial risks to which Inter is subject.

The model adopted by the Group involves a structure of areas and committees that seek to ensure:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Segregation of function;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Specific unit for risk management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Defined management process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Clear norms and competence structure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Defined limits and margins; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reference to best management practices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.Credit risk**

Credit risk is defined as the possibility of losses associated with the failure of the borrower or counterparty to meet their respective financial obligations in the agreed-upon terms or the devaluation of a credit agreement arising from the increased risk of default by the borrower, among others.

The financial instruments subject to credit risk are submitted to careful credit evaluation prior to contracting, as well as throughout the term of the respective operations. The credit analyses are based on the borrower's (or counterparty's) economic and financial capacity behavior, including payment history and credit reputation, in addition to the terms and conditions of the respective credit operation, including terms, rates and guarantees.

Loans and advances to customers, as shown in [Note](#ic5bfae344e9b43378a958aa0ff6d911e_70) 12, are mainly represented by the following operations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Credit card**: credit operations related to credit card limits, mostly without attached guarantees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Business loans:** working capital operations, receivables, discounts and loans in general, with or without attached guarantees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Real estate loans:** loans and financing operations secured by real estate, with attached guarantees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Personal loans:** loan and payroll card operations, personal loans with and without transfer guarantees; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Agribusiness loans:** financing operations to cover the costs of rural production, investment, commercialization and/or industrialization granted to rural producers, with or without attached guarantees.

Mitigation of Exposure

In order to maintain the exposures within the risk levels established by senior management, Inter adopts measures to mitigate credit risk. Exposure to credit risk is mitigated through the structuring of guarantees, adapting the risk level to be incurred to the characteristics of the collateral taken at the time of granting. Risk indicators are monitored on an on-going basis and proposal for alternatives forms of mitigation are assessed, whenever the exposure behavior to credit risk of any unit, region, product or segment requires it. Additionally, credit risk mitigation takes place through product repositioning and adjusting operational processes or operation approval levels.

In addition to the activities described above, goods pledged in guarantee are subject to a technical assessment / valuation at least once every twelve months. In the case of personal guarantees, an analysis of the financial and economic circumstances of the guarantor is made considering their other debts with third parties, including tax, social security and labor debt.

Credit standards guide operational units and cover, among other aspects, the classification, requirement, selection, assessment, formalization, control and reinforcement of guarantees, aiming to ensure the adequacy and sufficiency of mitigating instruments throughout the cycle of the loan.

In 2025 there were no material changes to the nature of the credit risk exposures, how they arise or the Group's objectives, policies and processes for managing them, although Inter continues to refine its internal risk management processes.

Measurement

The measurement of credit risk to the Group is carried out considering the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At the time that credit is granted, an assessment of a customer's financial condition is undertaken through the application of qualitative and quantitative methods and using information collected from the market, in order to support the adequacy of the risk exposure being proposed;

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The assessment is carried out at the counterparty level, considering information on guarantors where applicable. The exposure to the credit risk is also measured in extreme scenarios, using stress techniques and scenario analysis. The models applied to determine the rating of customers and loans are reviewed periodically in order to ensure they reflect the macroeconomic scenario and actual loss experience, as per information in note 12;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The aging of late payments in portfolios is monitored in order to identify trends or changes in the behavior of non-performing loans and allow the adoption of mitigating measures when required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expected credit loss reflects the risk level of loans and allows monitoring and control of the portfolio's exposure level and the adoption of risk mitigation measures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The expected credit loss is a forecast of the risk levels of the credit portfolio. Its calculation is based on the historical payment behavior and the distribution of the portfolio by product and risk level. This is a key input to the process of pricing loans and advances to customers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In addition to the monitoring and measurement of indicators under normal conditions, simulations of changes in business environment and economic scenario are also performed in order to predict the impact of such changes in levels of exposure to risks, provisions and balance of such portfolios and to support the process of reviewing the exposure limits and the credit risk policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.Description of guarantees**

The financial instruments subject to credit risk are subject to careful assessment of credit prior to being contracted and disbursed and risk assessment is ongoing throughout the term of the instruments. Credit assessments are based on an understanding of the customers' operational characteristics, their indebtedness capacity, considering cash flow, payment history and credit reputation, and any guarantees given.

Loans and advances to customers, as shown in Note 12, are mainly represented by the following operations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Working capital operations**: are guaranteed by receivables, promissory notes, sureties provided by their owners and occasionally by property or other tangible assets, when applicable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Payroll loans**: are mainly represented by payroll credit cards and personal loans. These are deducted directly from the borrowers' pensions, income or salaries and settled directly by the entity responsible for making these payments (e.g. company or government agency);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Personal loans and credit cards**: generally, do not have guarantees; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Real estate financing**: is collateralized by the real estate financed.

**Guarantees of real estate loans and financing**

The following table shows the value of real estate-backed financing, broken down by loan to value. Loan to Value (LTV) is the ratio between the value of a loan and the value of the asset being financed. A higher LTV may signal greater risk to the lender, as it indicates a lower share of the borrower's equity in the transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.Liquidity risk**

Liquidity risk represents the possibility that the Group will not be able to honor its financial obligations efficiently, whether expected or unexpected, including obligations arising from guarantees granted and extraordinary redemptions by customers. This risk also encompasses scenarios in which Inter may face difficulties in negotiating the sale of assets at market prices, either due to the significant volume in relation to the usual movement, or due to discontinuities or dysfunctions in the market.

Liquidity risk is managed institutionally through a governance structure, with responsibilities clearly distributed among the Board of Directors, the Asset and Liability Committee (ALCO), the Risk Committee, and the Chief Risk Officer (CRO). The latter is specifically responsible for monitoring and continuously tracking liquidity risk.

The risk management structure operates independently and proactively, aiming to continuously monitor liquidity indicators and prevent potential breaches of established limits. Management fully encompasses Inter&Co's cash receipts and payments, enabling the timely implementation of mitigation actions when necessary.

Liquidity risk monitoring is carried out daily, with monitoring conducted periodically by the Assets and Liabilities Committee (ALCO), which systematically assesses available liquidity risk information, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mismatch between assets and liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Concentration of the 10 largest investors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net Funding;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity limits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Maturity forecast;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Stress tests based on internally defined scenarios;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity contingency plans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Monitoring of Liquidity Ratio; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reports with information on positions held by Inter and its subsidiaries.

The structure considers the internal and external factors that impact the Group's liquidity, carrying out detailed daily monitoring of incoming and outgoing movements of loans and advances to customers, Term Deposits, Savings, Agribusiness Credit Notes (LCA), Real Estate Notes with Real Guarantee (LCI), Guaranteed Real Estate Notes (LIG) and Demand Deposits.

As of September 30, 2025, there were no material changes in the nature of liquidity risk exposures, monitoring methodology, internal policies, or the Group's processes for managing them. Nevertheless, the Group continues to continuously improve its internal risk management processes.

Market risk is defined as the possibility of losses resulting from fluctuations in the market values of positions held by the Institution and its subsidiaries, including the risks of transactions subject to fluctuations in exchange rates, interest rates, share prices and commodity prices.

At the Group, market risk management's main objective is to support business areas by establishing processes and implementing the necessary tools to assess and control related risks. This framework enables the measurement and monitoring of risk levels according to guidelines established by senior management.

Market risk management is monitored daily, with regular monitoring conducted by the Assets and Liabilities Committee (ALCO). Market risk controls enable analytical assessment of information and are constantly being refined. The Institution and its subsidiaries have been continually improving internal risk management and mitigation practices.

**Measurement**

Within the risk management process, the Group classifies its operations, including derivative financial instruments, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Trading book:** considers all operations intended to be traded before their contractual maturity or intended to hedge the trading portfolio and which are not subject to limitations on their negotiability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Banking book:** considers operations not classified in the trading portfolio, the main characteristic of which is the intention to hold the respective operations until maturity

In line with market practices, the Group manages its risks dynamically, seeking to identify, measure, evaluate, monitor, report, control and mitigate the exposures to market risks of its own positions. One of the methods of assessing the positions subject to market risk is the Value at Risk (VaR) model. The methodology used to calculate the VaR is the parametric model with a confidence level (CL) of 99% and a holding period of twenty one days.

We present the value-at-risk for the Trading Book positions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.Sensitivity analysis**

To determine the sensitivity of the Group's economic value position to market movements, we calculate the delta of the marked-to-market value (MTM) of assets and liabilities in different scenarios, considering the relevant risk factors, during the analyzed period. We present the results that would negatively affect our positions, according to each scenario.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Scenario 1:** based on market information, shocks of 1 basis point were applied to interest rates and 1% variation to prices (foreign currencies and shares);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Scenario 2:** shocks of 25% variation were determined in the curves and market prices; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Scenario 3:** shocks of 50% variation were determined in the curves and market prices.

It is important to note that the impacts reflect a static view of the portfolio, and that market dynamics and portfolio composition cause these positions to change continuously and do not necessarily reflect the position shown here. The group has a continuous market risk monitoring process, and in case of position/portfolio deterioration, mitigating actions are taken to minimize possible negative effects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.Operational risk**

Policy

Operational risk management aims to identify, assess and monitor risks, and is defined as the risk of losses resulting from inadequate or failed internal processes, people and systems, or external events. This definition includes legal risk, but excludes strategic and reputational risk.

Operational risk events can be classified:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Internal frauds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• External frauds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Labor demands and poor workplace safety;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inappropriate practices relating to end users, customers, products and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Damage to physical assets owned or used by the institution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Situations that lead to the interruption of the institution's activities or the discontinuity of services provided, including payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failures in information technology (IT) systems, processes or infrastructure; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failures in the execution, compliance with deadlines or management of the institution's activities, including those related to payment arrangements.

For payment activities, the clauses include: I - failures in the protection and security of sensitive data related to both end-user credentials and other information exchanged for the purpose of carrying out payment transactions; II - failures in the identification and authentication of the end user in a payment transaction; III - failures in the authorization of payment transactions; and IV - failures in initiating payment transactions.

Inter adopts the management model of the three lines of defense in light of its size, business model and risk appetite.

**Phases of the Management Process**

Qualitative Evaluation

The qualitative assessment uses a scale which considers measures for probability and impact, taking into account the vulnerabilities and threats that, combined, determine the level of risk exposure to each event. Identification and verification is performed by in-person monitoring, questionnaires, analysis of historical data, interviews and workshops with managers and employees from operational areas, business partners and business units.

The identified risks are categorized and organized by risk factors.

Qualitative assessment is an ongoing process, with regular monitoring and reviews to ensure that risks are being managed appropriately.

Quantitative Evaluation

In the quantitative assessment of operational risk, Inter maintains an internal database fed by various sources of information. This contains descriptions and details of operational losses. In the quantitative assessment, information from external sources deemed reliable and relevant to the businesses of the Group may also be used.

Quantitative assessment offers a structured, data-driven approach to measuring and managing operational risks.

Monitoring

An effective risk management process requires a communication and review structure that ensures the correct, effective and timely identification and assessment of the risks. In addition, it also seeks to assure that controls and responses to these risks are implemented.

Control tests and regular audits intended to verify compliance with applicable policies and standards are performed. The monitoring and review process seeks to verify whether:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The adopted measures have achieved the intended results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The procedures adopted and the information gathered to perform the assessment were appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Higher levels of knowledge may have contributed to make better decisions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• There is an effective possibility of obtaining information for future assessments.

**7. Fair values of financial instruments**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.Financial instruments – Classification and fair values**

Financial Instruments are classified into the following categories:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amortized cost;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fair value through other comprehensive income (FVOCI); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fair value through profit or loss (FVTPL).

The fair value of a financial asset or liability is measured using one of three approaches below, weighting the levels of the fair value hierarchy as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Level 1** – instruments with prices traded in the active market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Level 2** – using financial valuation techniques, weighing data and market variables; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Level 3** – uses meaningful variables that are not based on market data.

The following table presents the composition of financial assets and liabilities according to the accounting classification in fair value through other comprehensive income (FVOCI) and fair value through profit or loss (FVTPL). It also shows the carrying amounts and fair values of financial assets and liabilities, including their levels in the fair value hierarchy. Inter may not include information on the fair value of financial assets and liabilities when the carrying amount is a reasonable approximation of fair value.

The methodology used to measure financial assets and liabilities classified as "Level 2" uses information that is observable for the asset or liability at market; (i) from observations of the quoted price of similar items in an active market; (ii) identical items in a non-active market; or (iii) from other information extracted from related markets.

During the period ended September 30, 2025, there were no change in the measurement method of financial assets and liabilities that entailed reclassification of financial assets and liabilities among the different levels of the fair value hierarchy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;Refers to operations whose maturity, on the investment date, was equal to or less than 90 days and present an insignificant risk of change in fair value. Due to the short term and low volatility of these financial instruments, no provision for losses was made, since the credit risk is considered minimal and there is no expectation of significant variations in market value until maturity.

September 30, 2025, the expected credit losses of securities was R$43,645 (December 31, 2024: R$53,487).

Inter&CO classifies R$24,478,400 (91.1%) of the portfolio as low credit risk, mainly due to the predominance of Federal Government Bonds (Brazil). For this reason, no provisions are made for expected credit loss on this portion.

The remaining R$2,381,152 (8.9%) of the portfolio corresponds to assets that have inherent credit risk, and therefore are subject to assessment for the establishment of provisions. Securities and Bonds with credit risk are classified as follows: R$2,275,299 (95.6%) in stage 1 and R$53,318 (2.2%) in stage 2 and R$52,535 (2.2%) in stage 3.

The provisions for expected credit loss of Securities and Bonds total R$43,645, being: R$24,019 (55.0%) in stage 1 and R$2,898 (6.6%) in stage 2 and R$16,729 (38.3%) in stage 3.

**Swap contracts:** The swaps were carried out with the purpose of mitigating the market risk associated with the mismatch between the indexes of the mortgage loan portfolio and the indexes of the funding portfolio. September 30, 2025, Inter had liabilities indexed to the IGP-M index, with margin deposits and recognized at their fair value in the period's results.

**Forward agreements:** Forward contracts were negotiated to mitigate market risks arising from Inter's exposure and to meet client demands. Forward contracts represent the purchase or sale of a specific asset based on a pre-agreed price, with settlement on future dates.

**Futures contracts:** Futures contracts were entered into with the aim of mitigating (i) risks arising from exposures linked to the exchange rate, including investments abroad, as well as (ii) risks arising from the mismatch between interest rates on active positions and funding rates.

Transactions involving derivative financial instruments (futures contracts, currency forwards and swaps) are held in custody at B3 S.A. – BRASIL, BOLSA, BALCÃO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.Hedge accounting - exposure**

Inter&Co has a risk management strategy through hedging operations to mitigate exposure to interest rates, exchange rate fluctuations, and cash flows. To more accurately reflect the economic results of these strategies in the financial statements, the results are presented using a hedge accounting approach, implemented in accordance with the strategy and purpose of the structure. These may include: (i) Fair Value Hedge, (ii) Cash Flow Hedge, and (iii) Foreign Investment Hedge.

In this context, part of the result of the structure may be recognized directly in the income statement or in Other Comprehensive Income under Equity, net of tax effects, and transferred to the income statement in the event of ineffectiveness or liquidation of the hedge structure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Fair value hedge

Inter&Co's fair value hedging strategies aim to protect exposure to changes in fair value, specifically in interest receipts related to recognized assets. The hedged asset is adjusted to market value, as are the derivatives contracted to hedge it. Gains and losses on hedging instruments and hedged items are recognized simultaneously in profit or loss, reducing accounting volatility.

Below, we present the effects of hedge accounting on Inter&Co's financial position and performance:

---

|:---|:---|:---|
| | **09/30/2025** | **12/31/2024** |
| **Hedge instruments** | **9740794** | **6641295** |
| Future DI (a) | 3129830 | 3218086 |
| DAP (b) | 6610964 | 3396865 |
| *Swap (b)* |  | 26344 |
| **Hedge object** | **9740794** | **6546418** |
| Loans (a) | 3129830 | 3165012 |
| Real estate loans (b) | 6610964 | 3381406 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The hedging instrument used is the DI Future Rate. The hedged asset covers loan portfolios, including FGTS advance withdrawals and payroll loans; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The hedging instruments used are DAP and SWAP. The hedged asset covers the real estate loan portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Hedge of investments abroad

Inter&Co's net investment hedging strategies abroad aim to mitigate exposure to exchange rate fluctuations resulting from investments whose functional currency differs from the local currency, which impacts the organization's results. The effective portion of the hedge result is recognized in equity, with only the ineffective portion of the instrument transferred to profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The hedging instrument used is the dollar futures contract. The hedged asset is the investments in the subsidiaries (Cayman, Payments and Inter&Co) abroad.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.*Cash Flow Hedge*

Inter&Co's Cash Flow Hedge strategies aim to hedge exposure to variations in future cash flows, particularly interest payments and exchange rate fluctuations. The effective portion of the appreciation or depreciation of hedging instruments is recognized in equity and only transferred to profit or loss in two situations: (i) if the hedge is ineffective; and (ii) upon realization of the hedged asset.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Labor lawsuits

These are legal actions whose objective is to obtain compensation of a labor nature. The provisioned amounts refer, for the most part, to proceedings that discuss potential labor rights, such as claims for overtime pay and salary equalization. At Inter&Co, the methodology used for provisioning these contingencies is based on calculating the average ticket of concluded labor lawsuits, considering the total value of finalized proceedings divided by the amount effectively disbursed over the last 36 months.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Civil lawsuits

These comprise demands that aim, predominantly, for compensation for material and moral damages related to the Group's products and services, including declaratory and reparatory actions, matters referring to compliance with the 30% limit for payroll deductions of borrowers, requests for document presentation, and contract revision actions. The provisioning methodology adopted by Inter&Co for these contingencies is based on calculating the average ticket of finalized civil proceedings, obtained by dividing the total value of concluded actions by the amount effectively paid over the last 24 months.

(a) As part of the acquisition of Inter Pag Instituição de Pagamento S.A (formerly Granito), Inter&Co recognized a labor provision of R$5,367 and a civil provision of R$340.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.Contingent tax liabilities classified as possible losses**

The main proceedings with this classification are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Income tax and social contribution on net income – IRPJ and CSLL

On August 30, 2013, an infraction notice was issued (regarding expenses considered non-deductible) requiring the collection of income tax and social contribution amounts relating to the calendar years 2008 to 2009. As of September 30, 2025, the amount at risk of the action totals R$31,652 (December 31, 2024: R$30,312), while the total amount of the action corresponds to R$66,109 (December 31, 2024: R$63,301).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.COFINS

Inter is challenging COFINS assessments for the period from 1999 to 2014.

Before the publication of Law No. 12,973/14, which modified the understanding regarding the inclusion of financial revenues in COFINS calculation basis, there was discussion about the expansion of the calculation basis for said contribution promoted by paragraph 1 of article 3 of Law No. 9,718/98.

In 2005, Inter obtained a favorable final court decision (res judicata) from the Federal Supreme Court that ensured the financial institution's right to collect COFINS based only on service revenue, instead of total revenue which would include financial revenues.

During the period from 1999 to 2006, Inter made judicial deposits and/or performed payment of the obligation. In 2006, through a favorable decision from the Federal Supreme Court and express consent from the Federal Revenue Service, Inter's judicial deposit was released. Additionally, the authorization to use credits, for amounts previously overpaid, against current obligations, was approved without contestation by the Federal Revenue Service on May 11, 2006. Subsequently, the Federal Revenue Service questioned the procedures adopted by Inter, applying the understanding that financial revenues should be included in COFINS calculation basis.

After the publication of Law 12,973/14, Inter modified its procedures to include financial revenues in COFINS calculation basis, so that the taxable events involved in Inter's discussions all predate the law.

Currently, the application of res judicata is being discussed in a specific legal action that ensured Inter's right not to collect COFINS on its financial revenues, such that the Federal Supreme Court ruling in Theme 372 does not directly affect Inter's discussions. As of September 30, 2025, the amount at risk of the action totals R$71,829 (December 31, 2024: R$68,738), while the total amount of the action corresponds to R$160,656 (December 31, 2024: R$153,760).

**33.[Share-based payment](#ic5bfae344e9b43378a958aa0ff6d911e_142)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.Share-based compensation agreements**

a.1) Stock option plan - Banco Inter S.A.

Between February 2018 and January 2022, Banco Inter S.A. established stock option programs through which stock options were granted to Inter's management and executives for the acquisition of Banco Inter S.A. shares.

On January 4, 2023, an Extraordinary General Meeting of Inter&Co, Inc. was held, at which the migration of share-based payment plans was approved, with the consequent assumption by Inter&Co of Banco Inter S.A.'s obligations arising from the active plans and respective programs. As a result of the corporate reorganization, the number of options held by each beneficiary was proportionally adjusted. Thus, for every 6 stock options of ordinary or preferred shares of Banco Inter S.A., the beneficiary will have 1 stock option of Inter&Co Class A Share. Additionally, the re-pricing of the exercise price of options granted in 2022, which had not yet been exercised, was approved. Upon re-pricing, a new calculation of the fair value of the granted and unexercised options was performed, resulting in an additional amount of R$15,990 of incremental expense, to be recognized over the remaining vesting period.

The main characteristics of the plans are described below:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| **Grant Date** | **Final strike date** | **Options (shares INTR)** | **Vesting** | **Average strike price** | **Participants** |
| 02/15/2018 | 02/15/2025 | 5452464 | Up to 5 years | R$1.80 | Officers, managers and key employees |
| 07/09/2020 | 07/09/2027 | 3182250 | Up to 5 years | R$21.50 | Officers, managers and key employees |
| 01/31/2022 | 12/31/2028 | 3250000 | Up to 5 years | R$15.50 | Officers, managers and key employees |
