**Exchange Rates**

This Report contains translations of certain Chilean peso amounts into U.S. dollars at specified rates solely for the convenience of the reader. These translations should not be construed as representations that the Chilean peso amounts actually represent such U.S. dollar amounts, were converted from U.S. dollars at the rate indicated in preparing the Unaudited Interim Consolidated Financial Statements, could be converted into U.S. dollars at the rate indicated, were converted or will be converted at all.

Unless otherwise indicated, all U.S. dollar amounts at any year end, for any period have been translated from Chilean pesos based on the interbank market rate published by Reuters at 1:30 pm on the last business day of the period. On September 30, 2025 the exchange rate in the Informal Exchange Market as published by Reuters at 1:30 pm was Ch$961.65 per U.S.$1.00, or 0.04% more than the observed exchange rate published by the Central Bank for such date of Ch$961.24 per U.S.$1.00. The Federal Reserve Bank of New York does not report a noon buying rate for the Chilean peso.

The U.S. dollar equivalent of one UF was U.S.$41.08 as of September 30, 2025, using the observed exchange rate reported by the Central Bank as of September 30, 2025 of Ch$961.24 per U.S.$1.00, while the value of one UF as of September 30, 2025 was Ch$39,485.65.

**Dividends**

Under the current General Banking Law, a Chilean bank may not distribute provisional dividends. Santander-Chile's annual dividend is proposed by its Board of Directors and is approved by the Bank's shareholders at the annual ordinary shareholders' meeting held the year following that in which the dividend is generated. For example, the 2025 dividend must be proposed and approved during the first four months of 2026. Following shareholder approval, the proposed dividend is declared and paid. Historically, the dividend for a particular year has been declared and paid no later than one month following the shareholders' meeting. Dividends are paid to shareholders of record on the fifth day preceding the date set for payment of the dividend. The applicable record dates for the payment of dividends to holders of ADSs will, to the extent practicable, be the same.

Under the General Banking Law, a bank must distribute cash dividends in respect of any fiscal year in an amount equal to at least 30% of its net income for that year, if the dividend does not result in the infringement of minimum capital requirements. The balances of our distributable net income are generally retained for use in our business (including for the maintenance of any required legal reserves). Although our Board of Directors currently intends to pay regular annual dividends, the amount of dividend payments will depend upon, among other factors, our current level of earnings, capital and legal reserve requirements, as well as market conditions, and there can be no assurance as to the amount or timing of future dividends.

Dividends payable to holders of ADSs are net of foreign currency conversion expenses of The Bank of New York Mellon, as depositary (the "Depositary") and will be subject to the Chilean withholding tax currently at the rate of 35% (subject to credits in certain cases as described in "Item 10. Additional Information—E. Taxation—Material Tax Consequences of Owning Shares of Our Common Stock or ADSs" in our 2024 20-F).

Under the Foreign Investment Contract (as defined herein), the Depositary, on behalf of ADS holders, is granted access to the Formal Exchange Market to convert cash dividends from Chilean pesos to U.S. dollars and to pay such U.S. dollars to ADS holders outside Chile, net of taxes, and no separate registration by ADS holders is required. In the past, Chilean law required that holders of shares of Chilean companies who were not residents of Chile to register as foreign investors under one of the foreign investment regimes contemplated by Chilean law in order to have dividends, sale proceeds or other amounts with respect to their shares remitted outside Chile through the Formal Exchange Market. On April 19, 2001, the Central Bank deregulated the Exchange Market and eliminated the need to obtain approval from the Central Bank in order to remit dividends, but at the same time this eliminated the possibility of accessing the Formal Exchange Market. These changes do not affect the current Foreign Investment Contract, which was signed prior to April 19, 2001, which grants access to the Formal Exchange Market with prior approval of the Central Bank. See "Item 10. Additional Information—D. Exchange Controls" in our 2024 20-F.

**B.Risk Factors**

You should carefully consider the following risk factors, and the risk factors set forth under "Item 3. Key Information—D. Risk Factors" in our 2024 20-F, which should be read in conjunction with all the other information presented in this Report and in our 2024 20-F. The risks and uncertainties described below are not the only ones that we face. Additional risks and uncertainties that we do not know about or that we currently think are immaterial may also impair our business operations. Any of the following risks, if they actually occur, could materially and adversely affect our business, results of operations, prospects and financial condition.

We are subject to market risks that are presented both in this subsection and in "Item 5. Operating and Financial Review and Prospects" and "Item 11. Quantitative and Qualitative Disclosures about Market Risk" in our 2024 20-F.

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

A slowdown or recession in the global economy 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).

Volatile conditions in the global financial markets could also have a material adverse effect on us, including on our ability to access capital and liquidity on financial terms acceptable to us, if at all. If capital markets financing ceases to become available, or becomes excessively expensive, we may be forced to raise the rates we pay on deposits to attract more customers and become unable to maintain certain liability maturities. Any such increase 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;&nbsp;&nbsp;&nbsp;&nbsp;• Reduced demand for our products and services.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increased regulation of our industry. Compliance with such regulation would likely continue to increase our costs and may affect the pricing for our products and services, increase our conduct and regulatory risks related to non-compliance and limit our ability to pursue business opportunities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inability of our borrowers to timely or fully comply with their existing obligations. Macroeconomic shocks may negatively impact the income of our customers, both retail and corporate, and may adversely affect the recoverability of our loans, resulting in increased loan losses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The process we use to estimate losses inherent in our credit exposure requires complex judgements, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The value and liquidity of the portfolio of investment securities that we hold may be adversely affected.

The Chilean economy has expanded 1.2% as of November 2025 (the latest data available from the Central Bank) on an annualized basis, which is within the range of the Central Bank's initial estimates of GDP growth this year (1.5%-2.5%). The Chilean consumer price index reached 3.4% annually in November 2025, compared to 4.5% in 2024, while the Central Bank has continued to cut the monetary policy rate, from 5.00% at the end of 2024 to 4.50% as of December 2025.

Any changes to the current macroeconomic conditions which could cause market turmoil or economic recession in the future could have a material adverse effect on our financing availability and terms and, more generally, on our results, financial condition and prospects.

***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 conditions of our customers.

While inflationary pressures experienced in recent years (both in Chile and globally) have abated, there is no guarantee that such inflationary pressures will not resurface, which would lead to increases in interest rates and a slowdown of the world economy.

In addition, since early February 2025, the newly elected U.S. government announced the imposition of trade tariffs on several of its trade partners, including Chile. The imposition of tariffs by the U.S. could have a significant impact on international trade and supply chains, potentially resulting in lower global growth. Increased protectionism and trade tensions, such as the tensions between the United States and China during the prior Trump administration, could aggravate, which could have a negative impact on the economies in which we operate, and impact our results of operations, financial condition and prospects.

These or other conditions causing market turmoil or economic recession in the future could increase our non-performing loan ratios, impair our loan and other financial assets and result in decreased demand for borrowings and deposits in general. A worsening of macroeconomic conditions may also lead to significant volatility in financial markets. As a result, our customers may in the future 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 our business, financial condition and results of operations.

***We may generate lower revenues from fee and commission-based businesses.***

A portion of the Bank's fee income is derived from brokerage of mutual funds, stocks and bonds and a market downturn could result in significantly lower fees from these sources. The fees and commissions that we earn from the different banking and other financial services that we provide represent a significant source of our revenues. Regulatory changes that modify the fees we may charge could adversely affect our fee and commission income.

In April 2023, the Committee for the Setting of Interchange Fee Caps (Comité para la Fijación de Límites a las Tasas de Intercambio, an ad hoc, autonomous and technical committee) established new interchange fee caps for credit and debit

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

cards, reducing the fees which banks may charge from acquirers. Initially the Committee proposed the following gradual implementation of rate caps, as detailed in the table below:

---

| | | | |
|:---|:---|:---|:---|
| Card type | Initial rate | First cut (Oct-23) | Second cut (Oct-24) (Suspended) |
| Debit | 0.6% | 0.5% | 0.35% |
| Credit | 1.48% | 1.14% | 0.80% |
| Prepaid | 1.04% | 0.94% | 0.80% |

---

In order to assess the effects of the gradual implementation of the imposition limits on interchange rates, the Committee agreed to carry out an impact study on: (i) the application of the preliminary rates; (ii) the first reduction established; (iii) the assessment of the potential, or reasonably foreseeable, effects of the second reduction; and (iv) all aspects of the market that are relevant to the fulfillment of the Committee's objectives established in Law No. 21,365 of 2021. This report has not yet been published.

On September 30, 2024, the Committee indicated that it would begin a review process of the caps imposed on interchange fees, and that it would maintain the caps in force at such time (effectively suspending the reduction planned for October 2024 until further notice). If the suspension is lifted, and the cap on interchanged fees is lowered as originally planned, we anticipate a significant negative impact on our revenue from card fees which we had estimated at Ch$22 billion for 2025.

Banco Santander-Chile currently acts as a broker of Santander Asset Management S.A. Administradora General de Fondos S.A. Therefore, even in the absence of a market downturn, below-market performance by the mutual funds of the firm we broker for may result in a reduction in revenue we receive from selling asset management funds and adversely affect our results of operations.

***The growth of our loan portfolio may expose us to increased loan losses. Our exposure to individuals and small and mid-sized businesses could lead to higher levels of past due loans, allowances for loan losses and charge-offs.***

The further expansion of our loan portfolio (particularly in the consumer, small- and mid-sized companies and real estate segments) can be expected to expose us to a higher level of loan losses and require us to establish higher levels of provisions for loan losses. See "Note 13—Financial Assets at Amortized Cost" and "Note 11—Financial Assets At Fair Value Through Other Comprehensive Income" in our Unaudited Interim Consolidated Financial Statements for a description and presentation of our loan portfolio as well as "Item 2. Operating and Financial Review and Prospects—E. Selected Statistical Information- Loan Portfolio."

Retail customers represent 76.0% of the value of the total loan portfolio at amortized cost as of September 30, 2025. As part of our business strategy, we seek to increase lending and other services to retail clients, which are more likely to be adversely affected by downturns in the Chilean economy and other economic conditions, including high inflation. In addition, as of September 30, 2025, our residential mortgage loan portfolio totaled Ch$17,454,306 million, representing 42.6% of our total loans at amortized cost. See "Note 13—Financial Assets at Amortized Cost" in our Unaudited Interim Consolidated Financial Statements for a description and presentation of our residential mortgage loan portfolio. If the economy and real estate market in Chile experience a significant downturn, this could materially adversely affect the liquidity, businesses and financial conditions of our customers, which may in turn cause us to experience higher levels of past-due loans, thereby resulting in higher provisions for loan losses and subsequent charge-offs. This may materially and adversely affect our asset quality, results of operations and financial condition.

***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. Generally, in a declining interest rate environment, prepayment activity increases, which reduces the weighted average lives of our earning assets and could have a material adverse effect on us. We expect short-term rates to continue to fall in 2026, which could increase prepayment risk of our loan book, although the monetary policy rate is close to what the market believes to be the neutral rate. We would also be required to amortize net premiums into income over a shorter period of time, thereby reducing the corresponding asset yield and net interest income. Prepayment risk also has a significant adverse impact on credit card and collateralized mortgage loans, since prepayments could shorten the weighted average life of these assets, which may result in a mismatch

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

in our funding obligations and reinvestment at lower yields. Prepayment risk is inherent to our commercial activity and an increase in prepayments or a reduction in prepayment fees could have a material adverse effect on us. We cannot assure you that any future legal or regulatory changes related to prepayment fees will not have a material impact on our business.

***Credit, market and liquidity risk may have an adverse effect on our credit ratings and our cost of funds. Any downgrade in Chile's, our controlling shareholders or our credit rating would likely increase our cost of funding, require us to post additional collateral or take other actions under some of our derivative contracts and adversely affect our interest margins and results of operations.***

Credit ratings affect the cost and other terms upon which we can obtain funding. Rating agencies regularly evaluate us, and their ratings of our debt are based on several factors, including our financial strength and conditions affecting the financial services industry. In addition, due to the methodology of the main rating agencies, our credit rating is affected by the rating of Chile's sovereign debt. In October 2025, Moody's maintained its A2 (stable) credit rating for the Republic of Chile and Standard and Poor's affirmed its outlook for the Republic of Chile and maintained its A (stable) rating. If Chile's sovereign debt is downgraded, our credit rating would also likely be downgraded by an equivalent amount. In addition, our ratings may be adversely affected by any downgrade in the ratings of our parent company, Santander Spain.

Any downgrade in our debt credit ratings would likely increase our borrowing costs and require us to post additional collateral or take other actions under some of our derivative and other contracts, and could limit our access to capital markets and adversely affect our commercial business. For example, a ratings downgrade could adversely affect our ability to sell or market some of our products, engage in certain longer-term and derivatives transactions and retain our customers, particularly customers who need a minimum rating threshold in order to invest. In addition, under the terms of certain of our derivative contracts and other financial commitments, we may be required to maintain a minimum credit rating or terminate such contracts or require the posting of collateral. Any of these results of a ratings downgrade could reduce our liquidity and have an adverse effect on us, including our operating results and financial condition.

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 upon numerous dynamic, complex and inter-related factors and assumptions, including market conditions at the time of any downgrade, whether any downgrade of our long-term credit rating precipitates downgrades to 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 the preceding hypothetical examples, depending upon certain factors including which credit rating agency downgrades our credit rating, 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.

In addition, if we were required to cancel our derivatives contracts with certain counterparties and were unable to replace such contracts, our market risk profile could be altered.

There can be no assurance that the rating agencies will maintain the current ratings or outlooks. In general, the future evolution of the Bank's ratings will be linked, to a large extent, to the impact of the general global macroeconomic outlook, including as a result of the impact of the continuance or escalation of the wars in Ukraine and the Middle East, increases in tariffs for international trade, the local macroeconomic outlook, the evolution of Chile's political environment, the Chilean government's fiscal policy and the outlook of the Bank's asset quality, profitability and capital. Failure to maintain favorable ratings and outlooks could increase the Bank's cost of funding and adversely affect interest margins, which could have a material adverse effect on the Bank.

***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 local political issues, a higher interest rate environment and the wars in Ukraine and the Middle East. We have material exposures to securities, loans and other investments that are recorded at fair value and are therefore exposed 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 climate change or reputational requirements. In addition, the

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

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. As of September 30, 2025, the value of our debt instruments at fair value through other comprehensive income includes an unrealized net loss of Ch$70,741 million recognized as "Valuation accounts" in equity.

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, and reliable assumptions are difficult to make and are inherently uncertain and valuation models are complex, making them inherently 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.

***The value of the 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.***

The value of the collateral securing our loan portfolio may fluctuate or decline due to factors beyond our control, including macroeconomic or political factors affecting Chile's economy, the continuance or escalation of the wars in Ukraine and the Middle East. The value of the collateral securing our loan portfolio may be adversely affected by force majeure events, such as natural disasters (including as a result of climate change), particularly in locations where a significant portion of our loan portfolio is composed of real estate loans. Natural disasters such as earthquakes and floods may cause widespread damage, which could impair the asset quality of our loan portfolio and could have an adverse impact on Chile's economy. The real estate market is particularly vulnerable in the current economic climate and this may affect us, as real estate represents a significant portion of the collateral securing our residential mortgage loan portfolio. For example in May 2025, Law No. 21,748 was published in the Official Gazette, which creates a subsidy of up to 60 basis points on the interest rate applicable to the first acquisition of new houses with a value of up to UF4,000 (approximately U.S.$175,200) for up to 50,000 subsidies in total. It also includes a state guarantee from the Special Guarantee Fund (FOGAES) that covers up to 60% of the home's value, which could further reduce the total interest rate by up to 100 basis points. As of November 28, 2025, we have received requests for 3,612 mortgage loans under this program for a total of UF8,617,574. However, this program is temporary and may not be repeated in the future.

Furthermore, we may also not have sufficiently recent information on the value of collateral, 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 of our loans, which may materially and adversely affect our results of operations and financial condition.

In addition, technological changes in the auto industry, accelerated by environmental rules, could affect our auto consumer business in Chile, particularly residual values of leased vehicles. This transformation could affect our auto finance business in view of (i) a transition from fuel to electric engines, environmental aspects related to emissions and transition risks derived from political and regulatory decisions (e.g., traffic restrictions in city centers for certain cars based on emissions criteria); (ii) growing customer preferences for car leasing, subscription, car sharing and other services instead of vehicle ownership; (iii) greater market concentration in certain manufacturers, distributors and other agents; and (iv) more online sales channels. In addition, the auto industry could also suffer from supply chain disruption and shortages of batteries, semi-conductors and others in the wake of the wars, geopolitical and macroeconomic tensions, conflicts and other events, affecting guarantees, residual used car value and loan delinquencies. Although we monitor the auto portfolios and dealers and we have launched specific plans to tackle particular issues, the auto industry changes and disruptions described above could have a material adverse effect on our operating results, financial condition and prospects.

As of September 30, 2025, 61.0% of our loans and advances to customers, including contingent loan exposure are collateralized, which includes 8.2% of our consumer loans, 92.1% of our mortgage loans and 56.3% of our commercial loans.

***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. Non-performing or low credit quality loans have in the past negatively impacted our results of operations and could do so in the future. In particular, the amount of our reported credit impaired loans may

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

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 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 Chile or in global economic and political conditions, including as a result of inflationary pressures, increase in trade tariffs, supply chain issues, labor shortages and increases in commodity prices (including as a result of the continuance or escalation of the wars in Ukraine and the Middle East). In certain markets, the combined pressure of economic downturn, high inflation and high interest rates may impact the ability of our customers to repay their debt. If we are unable to control the level of our credit impaired or poor credit quality loans, this could have a material adverse effect on us.

As of September 30, 2025, our non-performing loans were Ch$1,257,571 million, and the ratio of our non-performing loans to total loans at amortized cost was 3.07% compared to 3.17% as of December 31, 2024. The decrease in this ratio was mainly due to initiatives undertaken in 2025 to improve the asset quality of the commercial portfolio, including write-offs, after a deterioration in commercial loans in 2024, mainly concentrated in the real estate and agricultural sectors, after the high interest rate environment of previous years and climate-related events that affected the agricultural sector in Chile. The high interest rate and high inflation environment in recent years has also affected the payment behavior of some of our mortgage clients. As of September 30, 2025, our allowance for expected credit losses for loans classified as financial assets at amortized costs (not including additional provisions) was Ch$1,315,955 million, and the ratio of these allowances for expected loan losses to total loans at amortized cost was 3.2%. For additional information on our asset quality, see "Item 2. Operating and Financial Review and Prospects- E. Selected Statistical Information-Analysis and Classification of Loan Portfolio Based on the Borrower's Payment Performance."

Our loan loss reserves are based on our current assessment of and expectations concerning various factors affecting the quality of our loan portfolio. These factors include, among other things, our borrowers' financial condition, repayment abilities and repayment intentions, the realizable value of any collateral, the prospects for support from any guarantor, Chile's economy, government macroeconomic policies, interest rates and the legal and regulatory environment. Because many of these factors are beyond our control and there is no infallible method for predicting loan and credit losses, we cannot assure you that our current or future loan loss and reserves 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 expected losses, we may be required to increase our loan loss reserves, which may adversely affect us. Additionally, in calculating our loan loss reserves, we employ qualitative and quantitative criteria and statistical models which may not be reliable in all circumstances and which are dependent upon data that may not be complete.

***We are subject to market, operational and other related risks associated with our derivative transactions 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).

Market practices and documentation for derivative transactions in Chile may differ from those in other countries. For example, documentation may not incorporate terms and conditions of derivatives transactions as commonly understood in other countries. In addition, the execution and performance of these transactions depend on our ability to maintain adequate control and administration systems. Moreover, our ability to adequately monitor, analyze and report derivative transactions continues to depend, largely, on our information technology systems. These factors further increase the risks associated with these transactions and could have a material adverse effect on us.

As of September 30, 2025, the fair value of the trading derivatives in our assets amounted to Ch$10,493,208 million with a notional value of Ch$270,509,076 million. Additionally, as of September 30, 2025, the fair value of trading derivatives in our liabilities totaled Ch$9,977,817 million with a notional value of Ch$250,657,957 million.

As of September 30, 2025, the nominal value of the hedging derivatives in our books within our financial risk management strategy and with the aim of reducing asymmetries in the accounting treatment of our operations amounted to Ch$30,078,418 million (with market value of Ch$408,424 million in assets and Ch$889,991 million in liabilities).

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

***We are subject to counterparty risk in our banking 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, clearing houses 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 clients. Defaults by, and even rumors or questions about the solvency of, certain financial institutions and the financial services industry generally have led to market-wide liquidity problems and could lead to losses or defaults by other institutions. Many of the routine transactions we enter into expose us to significant credit risk in the event of default by one of our significant counterparties.

***Liquidity and funding risks are inherent in our business and could have a material adverse effect on us.***

Liquidity risk is the risk that we either do not have sufficient financial resources available to meet our obligations as they are due, or we can only secure them at excessive cost. This risk is inherent in any banking business and can be heightened by a number of enterprise-specific factors, including over-reliance on a particular source of funding, changes in credit ratings or market-wide phenomena such as market dislocation, including as a result of increases in trade tariffs and the continuance or escalation of the wars in Ukraine and the Middle East. While we have in place liquidity management processes to mitigate and control these risks, systemic market factors make it difficult to eliminate these risks completely. Constraints in the supply of liquidity, including in inter-bank lending, could materially and adversely affect the cost of funding of our business, and extreme liquidity constraints may affect our current operations and our ability to fulfill regulatory liquidity requirements, as well as limit growth possibilities.

Our cost of obtaining funding is directly related to prevailing interest rates and to our credit spreads. The high interest rate environment currently prevalent in Chile and globally significantly increased the cost of our funding. Credit spreads variations are market-driven and may be influenced by market perceptions of our creditworthiness. Changes to interest rates and our credit spreads may occur frequently and could be unpredictable and highly volatile.

Additionally, in 2023, the Supreme Court of Chile established a new criterion regarding the applicable interest rates to foreign-currency transactions in Chile, denominated and payable in U.S. dollars, which since then are subject to the Maximum Conventional Rate (tasa máxima convencional or "TMC") published by the FMC. The Supreme Court ruled that: (a) the TMC applies to such transactions; and (b) if the applicable interest rate to a loan exceeds 50% of the interest that we charge over the then prevailing market rate (as calculated by the FMC at the time of the relevant loan transaction), such rate will be reduced to the then current interest rate (as calculated by the FMC). Any imbalance between the cost at which we fund our lending in U.S. dollars and the rate that we are allowed to charge to our debtors may have an adverse effect on our lending capabilities.

We rely, and will continue to rely, primarily on retail deposits to fund lending activities. The ongoing availability of this type of funding is directly related to our solvency and to the success of our policies, and it is also sensitive to a variety of factors beyond our control, such as general economic conditions and the confidence of retail depositors in the economy and in the financial services industry, and the availability and extent of deposit guarantees, as well as competition for deposits with other banks or with other products, such as mutual funds. Any of these factors could increase the amount of retail deposit withdrawals in a short period of time, thereby reducing our ability to access retail deposit funding on appropriate terms, or at all, in the future. If these circumstances were to arise, this could have a material adverse effect on our operating results, financial condition and prospects.

We anticipate that our customers will continue, in the near future, to make short-term deposits (particularly demand deposits and short-term time deposits), and we intend to maintain our emphasis on the use of banking deposits as a source of funds. As of September 30, 2025, 97.9% of our customer deposits had remaining maturities of one year or less or were payable on demand. A significant portion of our assets have longer maturities, resulting in a mismatch between the maturities of liabilities and the maturities of assets. Historically, one of our principal sources of funds has been time deposits. Time deposits represented 23.8% and 25.0% of our total liabilities and equity as of September 30, 2025 and 2024, respectively. The Chilean time deposit market is concentrated given the importance in size of various large institutional investors such as pension funds and corporations relative to the total size of the economy. As of September 30, 2025, the Bank's top 20 time deposits by economic group represented 26.2% of total time deposits, or 6.2% of total liabilities and

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

equity. No assurance can be given that future economic instability in the Chilean market will not negatively affect our ability to continue funding our business or to maintain our current levels of funding without incurring increased 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.

The short-term nature of this funding source could cause liquidity problems for us in the future if deposits are not made in the volumes we expect or are not renewed. If a substantial number of our depositors withdraw their demand deposits or do not roll over their time deposits upon maturity, we may be materially and adversely affected. Additionally, our activities could be adversely impacted by liquidity tensions arising from generalized drawdown of committed credit lines to our customers.

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.

***We are subject to liquidity requirements that could limit our operations, and changes to these requirements may further limit and adversely affect our operating results, financial condition and prospects.***

The FMC and the Central Bank published updated liquidity standards in 2015 and ratios that must be implemented and calculated by all banks. These new liquidity standards are in line with those established in Basel III. The most important liquidity ratios that have been adopted by Chilean banks are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity coverage ratio (LCR), which measures the percentage of liquid assets over net cash outflows. The new guidelines also define liquid assets and the formulas for calculating net cash outflows.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net Stable Funding Ratio (NSFR) which will measure a bank's available stable funding relative to its required stable funding. Both concepts are also defined in the new regulations.

The LCR is a liquidity standard that measures if banks have enough high-quality liquid assets to cover expected net cash outflows over a 30-day liquidity stress period. The net stable funding ratio (NSFR) provides a sustainable maturity structure of assets and liabilities such that banks maintain a stable funding profile in relation to their activities. As of September 30, 2025 our LCR and NSFR were 165% and 111%, respectively. While we are in compliance of regulatory requirements, no assurance can be made as to whether we will remain in compliance in the future. Moreover, there can be no assurance that the application of the existing regulatory requirements, standards or recommendations will not require us to issue additional securities that qualify as own funds or eligible liabilities, to maintain a greater proportion of its assets in highly-liquid but lower-yielding financial instruments, to liquidate assets, to curtail business or to take any other actions, any of which may have a material adverse effect on the our business, results of operations and/or financial position.

***Modifications to reserve requirements may affect our business.***

Deposits are subject to a reserve requirement of 9.0% for demand deposits and 3.6% for time deposits (with terms of less than one year). The Central Bank has statutory authority to require banks to maintain reserves of up to an average of 40.0% for demand deposits and up to 20.0% for time deposits (irrespective, in each case, of the currency in which these deposits are denominated) to implement monetary policy. In addition, to the extent that the aggregate amount of the following types of liabilities exceeds 2.5 times the amount of a bank's regulatory capital, a bank must maintain a 100% reserve against them: demand deposits, deposits in checking accounts, obligations payable on sight incurred in the ordinary course of business and, in general, all deposits unconditionally payable immediately. The General Banking Law also states that the FMC, with the approval from the Central Bank, may lower this threshold from 2.5 times to 1.5 times a bank's regulatory capital for a bank considered to be a SIB. This could lead to lower loan growth and have a negative effect on our business. As of September 30, 2024 and 2025, the Bank was not required to, and did not constitute, a corresponding technical reserve.

***Stricter banking regulations and changes to Chilean law may constrain our operations and thereby adversely affect our financial condition and results of operations.***

The FMC oversees and regulates the Chilean financial market, which is comprised of publicly traded companies, insurance companies, insurance brokers, mutual funds, fintech companies and investment funds as well as the Chilean

banking industry as a whole and some non-bank lenders. In addition to being subject to regulation by the FMC, in certain matters, we are also subject to regulations issued by the Central Bank.

Pursuant to the Chilean General Banking Act (Ley General de Bancos) Chilean banks may, subject to the approval of the FMC, engage in certain non-banking businesses approved by the law. The FMC's approval will depend on the risk associated with the activity and the bank's financial strength.

On December 12, 2023, the FMC published for public comment a proposal to amend RAN 21-13, addressing the framework for the Internal Capital Adequacy Assessment Process ("ICAAP") carried out by banks, the measurement of the Interest Rate Risk in the Banking Book ("IRRBB") and the definition of outlier banks, among other topics. On July 8, 2025, the FMC published Circular No. 2,365 containing the final amendments to this regulation, including: (i) the removal of the 15% threshold of the CET1 to determine additional capital requirements based on the metric of changes in the Economic Value of Equity ("ΔEVE") and the possibility to impose capital requirements for the full amount of interest rate risk in the banking book, based on either short-term or long-term exposures, (ii) establishment of a revised framework to determine outlier banks by maintaining the 15% threshold of the Tier 1 Capital based on ΔEVE while adding new thresholds for changes in Net Interest Income ("ΔNII") amounting to 5% of Tier 1 Capital and 18% of 12-month rolling Net Interest Income, conditions that, if individually met, will determine an outlier bank, (iii) introduction of certain technical modifications to the standardized model for computing interest rate risk in the banking book (ΔEVE and ΔNII) by allowing the netting for local currencies (CLP and CLF) while differentiating interest rate shocks for short- and long-term risk for CLF currency, (iv) the allowance for banks to use internal models in order to determine potential internal capital buffers associated with IRRBB, (v) the introduction of parameters on the framework the banks should follow in order to assess their risk profile and measure material risks, (vi) the incorporation of new guidelines for banks regarding the definition of internal capital targets by adopting the Pillar 2 Requirement and Pillar 2 Guidance concepts, (vii) the limitation of a maximum extension of 70 pages for the ICAAP Report, and (viii) the establishment of new disclosure requirements for Pillar 2 requirements. According to the schedule provided by the FMC, except for the new computation guidelines for IRRBB through ΔEVE and ΔNII, most of the changes will be in place for the 2026 ICAAP, to be delivered to the FMC in April 2027. Given the changes in the measurement of ΔEVE and ΔNII metrics, the definition of new thresholds for determining outlier banks and the revision made to the supervisory framework, we cannot rule out the imposition of further capital requirements to the banking industry in the future, including us. Therefore, we cannot assure you that our profitability will not be impacted by actions we may take in order to fulfill new regulatory thresholds in the future.

Future changes in laws and regulations may also cause us to face increased compliance costs and limitations on our ability to pursue certain business opportunities and provide certain products and services. We cannot generally assure you 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. Lastly, we cannot assure you that regulators will not impose more restrictive limitations in the future on the activities of banks, including us, than those that are currently in effect. Any such change in terms of capital and liquidity adequacy, credit risk provisioning, and consumer protection, among other matters, could have a material adverse effect on our results of operations or financial condition in a fashion that we cannot determine in advance.

***Changes in taxes, including the corporate income tax rate, in Chile may have an adverse effect on us and our clients.***

The Chilean government enacted several tax reforms in 2014, 2016 and 2020 in order to finance increased social spending. The most significant change was the increase in the corporate income tax rate to 27% in 2018. On October 24, 2024, the Congress approved a new tax reform aimed at increasing tax revenues by 1.5% of GDP. This reform includes measures to strengthen the tax authorities' powers to combat tax avoidance and evasion, such as changes to Chile's GAAP provisions, corporate reorganizations, the statute of limitations, and audit powers and procedures. In July 2025, the government introduced a proposed tax reform aimed at financing social spending. However, this was withdrawn by the Executive in August 2025. As of the date hereof, we cannot predict whether this or any tax reforms proposed in the future, will have a material impact on our business or our clients, nor can we rule out that additional reforms could be enacted in the future, which may have a material adverse effect on our results of operations. Please refer to "Item 10-Additional Information-E. Taxation" of our 2024 20-F for further details regarding the potential impact of these tax reforms on noteholders.

Additionally, on December 19, 2023, the Treaty to Avoid Double Taxation signed between Chile and the United States in 2010 (modified by two reservations in June 2023 by the U.S. Senate) (the "Treaty"), came into force, after the United States notified Chile of the completion of the approval procedure. The Treaty should not provide a more beneficial tax treatment on withholding taxes than the established Chilean domestic law regarding interest payments made under the notes to foreign holders.

***Developments in other countries may affect us, including the prices for our securities.***

The prices of securities issued by Chilean companies, including banks, are influenced to varying degrees by economic and market considerations in other countries. We cannot assure you that future developments in or affecting the Chilean economy, including consequences of economic difficulties in other markets, will not materially and adversely affect our business, financial condition or results of operations.

We are exposed to risks related to the weakness and volatility of the economic and political situation in Asia, the United States, Europe (including Spain, where Santander Spain, our controlling shareholder, is based), Brazil, Argentina and other nations. Although economic conditions in Europe and the United States may differ significantly from economic conditions in Chile, investors' reactions to developments in these other countries may have an adverse effect on the market value of securities of Chilean issuers. In particular, investor perceptions of the risks associated with our securities may be affected by perception of risk conditions in Spain.

If these, or other nations' economic conditions deteriorate, the economy in Chile, as both a neighboring country and a trading partner, could also be affected and could experience slower growth than in recent years, with possible adverse impact on our borrowers and counterparties. If this were to occur, we would potentially need to increase our allowances for loan losses, thus affecting our financial results, our results of operations and the price of our securities. As of September 30, 2025, the Bank's foreign exposure, including counterparty risk in the derivative instruments' portfolio, was U.S.$2,942 million or 4.1% of our total assets. There can be no assurance that the effects of a global recession will not negatively impact growth, consumption, unemployment, investment and the price of exports in Chile.

Chile has considerable economic ties with China, the United States and Europe. In the first nine months of 2025, approximately 36% of Chile's exports went to China, mainly copper. A slowdown in economic activity in China may affect Chile's GDP and export growth as well as the price of copper, which is Chile's main export. Chile exported approximately 17% of total exports to the United States and 13% to Europe in 2025. Crises, increases in tariffs and political uncertainties in these economies could also have an adverse effect on Chile, the price of our securities or our business.

In February 2025, the newly elected U.S. government announced the imposition of trade tariffs on several of its trade partners, including Chile. The U.S. government has also threatened to impose tariffs on various countries in Latin America for various commodities including copper, Chile's main export. The imposition of tariffs by the U.S. could have a significant impact on international trade and supply chains, potentially resulting in lower growth globally. Growing protectionism and trade tensions, such as the tensions between the United States and China during the prior administration of President Trump, could intensify, which could have a negative impact on the economies of the countries where we operate, and impact our operating results, financial condition and prospects.

Approximately 10% of Chile's exports in 2025 went to other Latin American nations. We cannot assure you that crises and political uncertainty in other Latin American countries will not have an adverse effect on Chile, the price of our securities or our business.

***A change in labor laws in Chile or a worsening of labor relations in the Bank could impact our business.***

As of September 30, 2025, on a consolidated basis, we had 8,583 employees, of which 72.9% were unionized. In December 2023, a new collective bargaining agreement was signed with the main unions, which became effective in September 2024 and will expire in December 2027. We generally apply the terms of our collective bargaining agreements to both union and non-union employees. While we have historically enjoyed good relations with our employees and their unions, we cannot assure you that a future strengthening of cross-industry labor movements will not have a material adverse effect on our business, financial condition or results of operations.

On April 26, 2023, Law No. 21,561 was published in the Official Gazette gradually reducing the working weekly hours from 45 to 40, without reduction of remuneration and allowing the working schedule to be distributed over a maximum of six days a week and a minimum of four days a week. On April 26, 2024, the ordinary working hours limit was reduced to 44 hours, in 2026 it will be reduced to 42 hours, and, in 2028, it will be reduced further to 40 hours per week. Additionally, employees that may be excluded from working hours limitations were limited to managers, administrators, agents with administrative powers and all those who work without immediate superior supervision due to the nature of their work. In this regard, the Labor Board will decide whether a certain job is adequately designated as a position without working hours limitations.

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

In addition, the minimum wage reached Ch$529,000 per month (U.S.$570 per month) on July 28, 2025. The law also established an automatic adjustment of the minimum monthly income to Ch$539,000 per month (U.S.$580 per month) as from January 1, 2026. At Santander Chile, the weekly working hours agreed under the new collective bargaining agreement were set at 40 hours and the monthly minimum wage at the Bank was set at Ch$1,030,000 (U.S.$1,108 per month) as of June 2024. However, we cannot assure you that the new labor reform, or any further minimum wage increases, will not have a material impact on our expenses.

Law No. 21,735, published in the Official Gazette of March 26, 2025, which created a new pension fund system in Chile, established a new employer contribution of 7% of its employees' taxable income, to be implemented gradually over 9 years, in addition to the existing 1.5% contributed by employers to the Disability and Survivors Insurance (*Seguro de Invalidez y Sobrevivencia* or "SIS"). This law increases employers' total contributions to 8.5% (apart from the 10% employees contribute monthly). The total 8.5% of employers contributions will be distributed as follows: (i) 4.5% for individual capitalization managed by the AFPs, with the aim of strengthening future pensions; (ii) 1.5% directed to a protected profitability contribution to help finance a new benefit "for years of contributions" for those already retired due to age or disability who meet the requirements; and (iii) the remainder 2.5% will be directed to the SIS and for a compensation for differences in life expectations. The contributions of 1.5% and 2.5% will be managed by a new Social Insurance entity in charge of financing (i) benefits with contributory elements; and (ii) benefits aimed at reducing the gender gap which will be administered by an Autonomous Fund of Social Security Protection (Fondo Autónomo de Protección Previsional).

On May 7, 2025, a bill was introduced in the Chilean Congress seeking to eliminate the maximum limit of 11 years of service used to calculate severance pay in cases of termination of the employment contract on the grounds of "company's needs" and "at the employer's will." The bill is currently in the First Constitutional Process in the Chamber of Deputies.

In December 2025 the outgoing administration announced a bill of law to establish a sectorial collective bargaining (negociación colectiva por "rama de actividad"), which if approved, may provide, for example, that banking labor unions can negotiate wages and salaries for the whole banking industry, thereby affecting the costs of the banks. We cannot assure you that this announced bill, if approved, or any further minimum wage increases, will not have a material impact on our expenses.

Finally, with the entry into force in December 2026 of the amendments introduced by Law No. 21,719 to Law No. 19,628 on Data Protection, the requirements governing the processing of personal data including employees' personal information will become significantly more stringent. These amendments introduce substantial changes regarding the legal bases for processing personal data, the rules applicable to international data transfers, the regulation of data processing mandate agreements, and the creation of the Personal Data Agency, which will be empowered to impose administrative fines, depending on the severity of the infringement.

These and any additional legislative or regulatory actions in Chile, Spain, the European Union, the United States or other countries, and any required changes to our business operations as a result of such laws and regulations, could result in reduced capital availability, significant loss of revenue, limit our ability to continue organic growth (including increased lending), pursue business opportunities in which we might otherwise consider engaging, provide certain products and services, affect the value of assets that we hold, require us to increase our prices and thereby reduce demand for our products, impose additional costs on us or otherwise adversely affect our business. Accordingly, we cannot assure you that such new laws or regulations will not adversely affect our business, results of operations or financial condition in the future.

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

We utilize, and are continuing to explore further uses of, artificial intelligence (AI) in connection with our business, products and services. Our company integrates AI and machine learning (ML) technologies into various aspects of our operations, products, and services. These technologies are used to enhance efficiency, automate processes, analyze data, and improve decision-making. In particular, the Bank has been integrating AI and ML in Customer Engagement, Personalized Marketing & Customer Insights, Process Automation & Back-Office Operations, Predictive Analytics, Fraud Detection, & Risk Management, Credit Scoring & Loan Approvals, Trading & Investment Advisory, Regulatory Compliance & Anti-Money Laundering, Cybersecurity, among others. During 2025, the Strategy of Data and AI Vice Presidency was created, reporting directly to the CEO, with the aim of facilitating the incorporation of AI transversally within the Bank.

However, 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 algorithms may be flawed, insufficient,

of poor quality, reflect unwanted forms of bias or contain other errors or inadequacies, any of which may not be easily detectable, AI has been known to produce false inferences or outputs, AI may subject us to new or heightened legal, regulatory, ethical 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, which could impair the acceptance of AI solutions, including those incorporated into our products and services. 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. Further, 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, if any of our employees, contractors, vendors or service providers use any third-party AI-powered solutions in connection with our business, it may lead to the inadvertent public disclosure of our proprietary, confidential, sensitive or personal information which may impact our ability to realize the benefit of our intellectual property or proprietary, confidential, sensitive or personal information, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **C. Recent Developments**

*Presidential and Congressional Elections*

On December 14, 2025, the presidential runoff election between José Antonio Kast and Jeannette Jara took place. Jeannette Jara, a member of the Communist Party and a left coalition candidate also backed by Frente Amplio (a left-progressive party) and center-left parties, received approximately 41.84% of the votes, while José Antonio Kast, a member of the Republican Party (*Partido Republicano*) and conservative candidate also backed by the National Libertarian Party (*Partido Nacional Libertario*), a right party, and center-right parties, received approximately 58.16% of the votes, becoming the elected President of the Republic. Mr. Kast will take office on March 11, 2026, succeeding President Gabriel Boric.

President-elect José Antonio Kast has stated that he intends to implement significant changes to the current political, social and economic frameworks, with a strong emphasis on public security and law enforcement policies as well as economic growth. His stated priorities include strengthening border protection to address illegal immigration, increasing penalties for organized crime and reducing the tax burden on individuals and businesses.

*Sale of 49.99% of Getnet Chile S.A.*

On December 23, 2025, the Board of Directors announced an extraordinary meeting of our shareholders scheduled for January 27, 2026 in order for the Bank's shareholders to vote in connection with (i) the offer made by Getnet Payments, S.L., a company of the Santander Group, to acquire 49.99% of the shares of Sociedad Operadora de Tarjetas de Pago Santander Getnet Chile S.A. ("Getnet") in exchange for a lump sum payment of Ch$68,000,000,000, and (ii) the execution of an agreement between us and Getnet, with a value that ranges from Ch$55,465,000,000 and Ch$79,999,000,000, by means of which we will share and use our personnel, branches, equipment and data to promote Getnet's products and services for a term of seven years, in exchange for 10% of the DIAO (defined as the discount fee minus interchange fees minus assessment fees plus other revenues) received by Getnet as a result of such services.

**ITEM 2. OPERATING AND FINANCIAL REVIEW AND PROSPECTS**

**A.Accounting Standards and critical accounting policies**

Please see Note 2 to our Unaudited Interim Consolidated Financial Statements as of September 30, 2025.

**B.Differences between IFRS and Chilean Bank GAAP**

Chilean Bank GAAP, as prescribed by the Compendium of Accounting Standards of the FMC (the "Compendium"), differs in certain respects from IFRS. The main differences that should be considered by an investor are the following:

*Suspension of Income Recognition on Accrual Basis*

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

In accordance with the Compendium, financial institutions must suspend recognition of income on an accrual basis in their statements of income for certain loans included in the impaired portfolio. IFRS 9 does not allow the suspension of accrual of interest on financial assets for which an impairment loss has been determined. Under IFRS 9, interest income is calculated by applying the effective interest rate to the gross carrying amount of financial assets, except for financial assets that have subsequently become credit-impaired (or "Stage 3"), for which interest revenue is calculated by applying the effective interest rate to their amortized cost (i.e., net of ECL provision). Off-balance interests are recorded as interest income only if the Bank receives the related payments. This difference does not materially impact our Unaudited Interim Consolidated Financial Statements.

*Charge-offs and Accounts Receivable*

The Compendium requires companies to establish deadlines for the charge-off of loans and accounts receivable. IFRS does not require any such deadline for charge-offs. A charge-off due to impairment would be recorded, if and only if, all efforts at collection of the loan or account receivable had been exhausted. Accordingly, this difference does not materially impact our Unaudited Interim Consolidated Financial Statements.

*Assets Received in Lieu of Payment*

The Compendium requires that the initial value of assets received in lieu of payment be the value agreed upon with a debtor as a result of the loan settlement or the value awarded in an auction, as applicable. These assets are required to be written off one year after their acquisition, if the assets have not been previously disposed of. IFRS requires that assets received in lieu of payment be initially accounted for at fair value. Subsequently, asset valuation depends on the classification provided by the entity for that type of asset. No deadline is established for charging-off an asset. The Bank has adjusted its Unaudited Interim Consolidated Financial Statements, accordingly.

*Loan loss allowances*

According to both Chilean Bank GAAP and IFRS, loan loss allowances are calculated using expected loss models. The models adopted with IFRS 9 used an expected loss approach, however these are not in accordance with specific guidelines under Chilean Bank GAAP given by the FMC. The FMC has not yet adopted impairment under IFRS 9 for banks and therefore the Bank has adjusted the Unaudited Interim Consolidated Financial Statements to fully comply with IFRS standards.

*Provisions for country risk and for contingent loan risk*

Under Chilean GAAP, the Bank provisions for country risk to cover the risk taken when holding or committing resources with any foreign country. These allowances are established according to country risk classifications established by the FMC and therefore are not in accordance with IFRS as issued by the IASB. Our Unaudited Interim Consolidated Financial Statements have been adjusted accordingly.

Under Chilean GAAP, the Bank has established allowances related to the undrawn available credit lines and contingent loans in accordance with the FMC. Provisions for contingent loans are calculated based on expected credit loss. The Bank has adjusted its Unaudited Interim Consolidated Financial Statements accordingly.

*Mark-to-market of debt instruments at amortized cost*

In the past years and in response to the COVID-19 pandemic, the Chilean government rolled out a series of measures to increase liquidity for households, which included passing a law that enabled Chileans to make up to three withdrawals from their pension fund. See "Item 5. Operating and Financial Review and Prospects—A. Operating Results-Chilean Economy" for more information. The increased liquidity of our clients led to an increase in demand deposits that surpassed the technical reserve threshold defined by the Central Bank as 2.5 times the Bank's regulatory capital. Therefore, the Bank was required to maintain a 100% reserve requirement in the Central Bank for any deposit unconditionally payable immediately that surpassed this threshold. This reserve requirement may also be composed of notes issued by the Central Bank. Additionally, in 2020 and 2021 the Central Bank issued low-cost Central Bank Credit lines (&nbsp;&nbsp;&nbsp;&nbsp;"FCIC"), whereby banks had to provide eligible collateral to access these lines. The eligible collateral included debt instruments issued by the Central Bank and the Chilean Treasury. Due to exceptional changes arising in the liquidity market, the Bank created a new business model "Held-to-collect" whose objective is to properly manage the prevailing high level of liquidity, and maintain the required reserves and collateral. As a result, the Bank reclassified a portion of the portfolio of high rated Central Bank bonds from debt instruments at fair value through other comprehensive income to debt instruments at amortized cost that matched the estimated duration of our excess technical reserves and the duration of the FCIC lines with the Central Bank.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

Under IFRS 9, the financial asset is reclassified at its fair value at the reclassification date, and the cumulative gain or loss previously recognized in other comprehensive income is removed from equity. As a result, the financial asset is measured at the reclassification date as if it had always been measured at amortized cost and the cumulative gain or loss previously recognized in OCI is removed from equity and applied against the fair value of the financial asset at the reclassification date.

*Perpetual bonds*

The Bank has classified the perpetual bonds it has issued as other equity instruments issued other than capital in accordance with IFRS, with interest being recognized in interest expense in the consolidated statement of income. Under Chilean Bank GAAP these instruments are recognized as liabilities under the line item issued regulatory capital financial instruments, with interest recognized in equity.

*Additional Provisions* 

According to FMC regulation, with Board approval, a bank would be allowed to establish additional provisions over the provision limits already described, to protect themselves from the risk of non-predictable economical fluctuations that could affect the macro-economic environment or a specific economic sector. According to No. 10 of Chapter B-1 from the FMC Compendium of Accounting Standards (Compendio de Normas Contables), these provisions will be recorded in liabilities, like provisions for contingent loans.

*Deferred taxes*

The Bank records, when appropriate, deferred tax assets and liabilities for the estimated future tax effects attributable to differences between the carrying amount of assets and liabilities and their tax bases. Due to the adjustments made to the consolidated financial statements, we adjust deferred taxes accordingly.

*Provision for mandatory dividends*

This provision is made in accordance with the Bank's internal policy, pursuant to which at least 30% of net income for the period is distributed, except when accumulated losses coming from previous year are to be absorbed or in the case of a contrary resolution adopted at the respective shareholders' meeting by unanimous vote of the outstanding shares. While the Bank uses the same policy under Chilean GAAP and IFRS, the net income used to calculate the provision is adjusted in accordance with IFRS principles. However, for the distribution of dividends, the Bank uses the net income according to Chilean GAAP.

*Exchange rate of provisions for credit risk*

In accordance with FMC regulations and Chilean GAAP, the Bank recognizes the gain or loss incurred by the exchange rate difference arising from provision of credit risk for loans in foreign currency. As the credit risk provision is adjusted under IFRS 9, the exchange rate difference is also adjusted.

**C.Operating Results**

**Chilean Economy**

All of our operations and substantially all of our customers are located in Chile. Accordingly, our financial condition and results of operations are substantially dependent upon economic conditions prevailing in Chile. In 2025, Chile experienced a moderate increase in economic activity compared to the previous year as lower interest rates in Chile and globally drove growth. Chile's economy grew 2.2% annually as of October 2025. The Central Bank's reference rate, which is used to set monetary policy, finished 2024 at 5.00% and following two rate cuts in 2025, as of December 2025, the reference rate is now at 4.50%. According to the latest data available as of November 2025, the unemployment rate for 2025 was 8.40%, a decrease from 8.53% as of September 30, 2024. The observed exchange rate appreciated 3.1% in the nine months ended September 30, 2025.

Total loans as of September 30, 2025, in the Chilean financial system, excluding loans held abroad by Chilean banks, grew 5.4% year-over-year. Total customer deposits (defined as time deposits plus checking accounts), excluding amounts held by Chilean banks abroad, increased 4.0% year-over-year as of September 30, 2025. The non-performing loans (defined as loans with an installment that is at least 90 days past-due) to total loans ratio remained stable between September 30, 2024 and September 30, 2025 at 2.4%.

***The Unidad de Fomento (UF) and the Impact of Inflation***

Our assets and liabilities are denominated in Chilean pesos, Unidades de Fomento (UF) and foreign currencies. Inflation impacts our results of operations as some loan and deposit products are contracted in UF. The UF is revalued in monthly cycles. Each day in the period beginning on the tenth day of the current month through the ninth day of the succeeding month, the nominal peso value of the UF is indexed up (or down in the event of deflation) in order to reflect a proportionate amount of the change in the Chilean Consumer Price Index during the prior calendar month. One UF equaled Ch$39,485.65 as of September 30, 2025 and Ch$37,910.42 as of September 30, 2024. High levels of inflation in Chile could adversely affect the Chilean economy and could have an adverse effect on our business, financial condition, and results of operations. Negative or decreasing inflation rates also negatively impact on our results. Inflation measured as the annual variation of the UF was 4.16% in the nine months ended September 30, 2025. There can be no assurance that Chilean inflation will not change significantly from the current level. Due to the current structure of our assets and

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

liabilities (i.e., a significant portion of our loans are indexed to the inflation rate compared to our deposits and other funding sources), there can be no assurance that our business, financial condition and result of operations in the future will not be adversely affected by changing levels of inflation. In summary:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *UF-denominated assets and liabilities.* The effect of any changes in the nominal peso value of our UF-denominated interest earning assets and interest-bearing liabilities is reflected in our results of operations as an increase (or decrease, in the event of deflation) in interest income and expense, respectively. Our net interest income will be positively affected by an inflationary environment to the extent that our average UF-denominated interest earning assets exceed our average UF-denominated interest-bearing liabilities. Our net interest income will be positively affected by deflation in any period in which our average UF-denominated interest-bearing liabilities exceed our average UF-denominated interest earning assets. Our net interest income will be negatively affected in a deflationary environment if our average UF-denominated interest-earning assets exceed our average UF-denominated interest-bearing liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Inflation and interest rate hedge.* A key component of our asset and liability policy is the management of interest rate risk. The Bank's assets generally have a longer maturity than our liabilities. As the Bank's mortgage portfolio grows, the maturity gap tends to rise as these loans, which are contracted in UF, have a longer maturity than the average maturity of our funding base. As most of our long-term financial instruments and mortgage loans are contracted in UF and most of our deposits are in nominal pesos, the rise in mortgage lending increases the Bank's exposure to inflation and to interest rate risk. This gap's size is limited by internal and regulatory guidelines to avoid excessive potential losses due to strong shifts in interest rates or inflation. To keep this duration gap below internal and regulatory limits, the Bank issues long term bonds denominated in UF or interest rate swaps. The financial cost of the bonds and the efficient part of these hedges is recorded as net interest income. The loss from the swaps taken to hedge mainly for inflation and interest rate risk, and included in net interest income, totaled a loss of Ch$216,163 million in the nine months ended September 30, 2025 and a loss of Ch$419,352 million in the nine months ended September 30, 2024. The lower losses in 2025 were mainly due to lower short-term interest rates and inflation in 2025 compared to 2024. The average gap between our interest earnings assets and total liabilities linked to the inflation, including hedging, was Ch$7,680,774 million in the nine months ended September 30, 2025 and Ch$7,641,618 million in the nine months ended September 30, 2024. Therefore, our sensitivity to a 100-basis point shift in UF inflation considering our average gap in 2025-to-date would be approximately Ch$77 billion.

The financial impact of the gap between our interest earning assets and liabilities denominated in UFs including hedges was as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **As of September 30,** | **As of September 30,** | **% Change** |
| | **2025** | **2024** | **2025/2024** |
| | **(in millions of Ch$)** | **(in millions of Ch$)** | |
| **Impact of inflation on net interest income** |  |  |  |
| Results from UF GAP(1) | (512486) | (513932) | (0.3)% |
| Annual UF inflation | 2.8% | 3.0% |  |

---

(1)UF GAP is net interest income from asset and liabilities denominated in UFs and include the results from hedging the size of this gap via interest rate swaps.

The similar results experienced in 2025 when compared to 2024 were mainly due to a similar rate of UF inflation in both periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Peso-denominated assets and liabilities.* Interest rates prevailing in Chile during any period primarily reflect the inflation rate during the period and the expectations of future inflation. The sensitivity of our peso-denominated interest earning assets and interest-bearing liabilities to changes to such prevailing rates varies. See "Item 2. Operating and Financial Review and Prospects—C. Operating Results—Interest Rates." We maintain a substantial amount of non-interest-bearing peso-denominated demand deposits. Because such deposits are not sensitive to inflation, any decline in the rate of inflation would adversely affect our net interest margin on assets funded with such deposits, and any increase in the rate of inflation would increase the net interest margin on such assets. The

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

ratio of the average of such demand deposits and average shareholder's equity to average interest-earning assets was 33.6% in the nine months ended September 30, 2025.

***Interest Rates***

Interest rates earned and paid on our assets and liabilities reflect, to a certain degree, inflation, expectations regarding inflation, changes in the short-term interest rates set by the Central Bank and movements in the long-term real rates. The Central Bank manages short-term interest rates based on its objectives of balancing low inflation and economic growth. Because our liabilities are generally re-priced sooner than our assets, changes in the rate of inflation or short-term rates in the economy are reflected in the rates of interest paid by us on our liabilities before such changes are reflected in the rates of interest earned by us on our assets. Our Financial Management Division usually seeks to maintain liabilities with an average duration that is shorter than that of our assets, including through the use of derivatives, in order to hedge against sudden or rapid falls in the inflation rate, which in general triggers a reduction in short-term rates. Therefore, when short-term interest rates fall, our net interest margin is positively impacted, but when short-term rates increase, our interest margin is negatively affected. An increase in long-term rates has a positive effect on our net interest margin, because our interest-earning assets generally have longer terms than our interest-bearing liabilities. A flattening of the yield curve (i.e. long-term rates falling quicker than short-term rates) negatively affects our margins by lowering loan yields at a greater pace than deposits costs. In addition, because our peso-denominated liabilities have relatively short re-pricing periods, they are generally more responsive to changes in inflation or short-term rates than our UF-denominated liabilities. As a result, during periods when expected inflation exceeds the previous period's inflation, customers often switch funds from UF-denominated deposits to peso-denominated deposits, which generally bear higher interest rates, thereby adversely affecting our net interest margin.

***Foreign Exchange Fluctuations***

The Chilean government's economic policies and any future changes in the value of the Chilean peso against the U.S. dollar could adversely affect our financial condition and results of operations. The Chilean peso has been subject to significant devaluation in the past and may be subject to significant fluctuations in the future. The exchange rate appreciated 3.3% in the nine months ended September 30, 2025, depreciated 4.3% in the same period in 2024. A significant portion of our assets and liabilities are denominated in foreign currencies, principally the U.S. dollar, and we historically have maintained and may continue to maintain material gaps between the balances of such assets and liabilities. Our current strategy is not to maintain a significant difference between the balances of our assets and liabilities in foreign currencies. In either case, any differences are usually hedged using forwards and cross-currency swaps. Including derivatives, the Bank seeks to run minimal foreign currency risk in its non-trading balance sheet. Because such assets and liabilities, as well as interest earned or paid on such assets and liabilities, and gains and losses realized upon the sale of such assets, are translated to Chilean pesos in preparing our financial statements, our reported income is affected by changes in the value of the Chilean peso relative to foreign currencies (principally the U.S. dollar). The translation gain or loss over assets and liabilities (excluding derivatives held for trading) and derivatives accounted under hedge accounting standards are included as foreign exchange transactions in the income statement. The translation and mark-to-market of foreign currency derivatives held for trading is recognized as a gain or loss in the net results from mark-to-market and trading. The Bank also uses a sensitivity analysis with both internal limits and regulatory limits to seek to manage the potential loss in net interest income resulting from fluctuations of interest rates on U.S. dollar denominated assets and liabilities and a VaR model to limit foreign currency trading risk.

See "Item 4. Quantitative and Qualitative Disclosures About Market Risk—Market Risks—Foreign exchange fluctuations" for more detail on the Bank's exposure to foreign currency.

***Segmentation Criteria***

The accounting policies used to determine the Bank's income and expenses by reporting segment are the same as those described in the summary of accounting policies in "Note 1—Summary of Significant Accounting Policies" of the Bank's Consolidated Financial Statements and are customized to meet the needs of the Bank's management. The Bank earns most of its income in the form of interest income, fee and commission income and income from financial operations.

To evaluate a segment's financial performance and make decisions regarding the resources to be assigned to segments, the Chief Operating Decision Maker (CODM) bases his or her assessment on the segment's interest income, fee and commission income, and expenses. The Bank's reporting segments have three Chief Operating Decision Makers: (i) the Director of Retail banking, (ii) the Director of the Middle-market segment and (iii) the Director of Corporate Investment Banking, each of which report to our Chief Executive Officer. All reporting segment information is presented following this structure.

Under IFRS 8, the Bank has aggregated operating segments with similar economic characteristics according to the aggregation criteria specified in the standard. A reporting segment consists of clients that are offered differentiated but, considering how their performance is measured, homogenous services based on IFRS 8 aggregation criteria. The clients included in each business segment are constantly revised and reclassified if a client no longer meets the criteria for the segment they are in and transferred to a different CODM. Therefore, variations of loan volumes and profit and loss items reflect business trends as well as client migration effects. Overall, this aggregation has no significant impact on the understanding of the nature and effects of the Bank's business activities and the economic environment.

The Bank's reportable segments are (i) Retail banking, (ii) Middle-market, (iii) Corporate Investment Banking and (iv) Corporate Activities ("Other"). See "Note 3—Reporting Segments" of our Audited Consolidated Financial Statements for more information.

Net income attributable to shareholders of the Bank increased 37.3% in the nine months ended September 30, 2025 compared to the same period in 2024 and totaled Ch$797,869 million. Our return on annualized average equity was 23.0% in the nine months ended September 30, 2025 compared to 17.6% in the same period of 2024.

Our net interest income increased 16.6% to Ch$1,572,804 million in the nine months ended September 30, 2025 compared to the same period in 2024. This increase was mainly due to the improved asset and funding mix and the impact of lower rates on funding more than offset the impact of lower inflation and rates on interest-earning assets, which drove our net interest margin to increase from 3.24% in 2024 to 3.86% in 2025.

Net fees and commission income increased 8.0% to Ch$441,142 million in the nine months ended September 30, 2025 compared to the same period in 2024. Fee growth in the nine months ended September 30, 2025 was driven by client growth and cross-selling indicators driven by greater availability and usage of our digital platforms. This resulted in significant increases in products such as cards, mutual fund brokerage, checking accounts, and Getnet.

Total net income from financial operations reached Ch$215,367 million and increased 19.3% in the nine months ended September 30, 2025 compared to the same period in 2024. These results include the results of our Treasury Division's trading business and financial transactions with customers, as well as the results of our Financial Management Division. The increase was mainly due to higher gains on the trading portfolio and gains on the available-for-sale portfolio compared to a loss for the nine months ended September 30, 2024, which were offset by lower results from the foreign currency position and the valuation of derivative contracts in the period.

Operating expenses in the nine months ended September 30, 2025 increased 3.1% compared to the corresponding period in 2024. The efficiency ratio was 35.9% and 40.0% for the nine months ended September 30, 2025 and 2024, respectively. In early 2025, the Bank celebrated the main milestone of the Gravity project, its migration from the mainframe servers to a cloud-based server. In January 2025, we transitioned processing to our new cloud-based server, which resulted in higher expenses related to the changeover and write-downs and impairment recognition related to legacy systems. This explains the 9.2% increase in the period in administrative expenses. Personnel salaries and expenses in the nine months ended September 30, 2025 increased 3.2% compared to the corresponding period in 2024, mainly due to wage adjustment for inflation, which was partially offset by a lower headcount. Depreciation and amortization expense decreased 4.3% in the nine months ended September 30, 2025 compared to the same period in 2024, mainly due to lower expense of internally generated software. Other operating expenses decreased 12.5% in nine months ended September 30, 2025 compared to the same period in 2024 mainly due to lower restructuring charges related to our branch network and digital transformations and lower expenses related to frauds.

Total operating income was Ch$2,177,204 million in the nine months ended September 30, 2025 and increased 14.8% compared to the same period in 2024 driven by the aforementioned rise in net interest income, fee income and financial operations. These increases, coupled with a 3.1% increase in operating expenses resulted in a 22.6% increase in the nine months ended September 30, 2025 compared to the same period in 2024 of Net operating income before credit losses.

Provisions for loan losses totaled Ch$430,389 million in the nine months ended September 30, 2025 and increased 9.4% compared to the same period in 2024. This rise was mainly due to an increase in the provision expense for commercial loans mainly due to the ongoing weakness in the construction and agricultural sectors and mortgage loans. This was partially offset by a 30.3% increase in recovery of loans previously charged-off.

Total income tax expense by the Bank was Ch$156,229 million in the nine months ended September 30, 2025 and increased 1.4% compared to the same period in 2024. The Bank paid an effective tax rate of 16.2% in 2025 compared to 20.7% in 2024. The statutory corporate tax rate in Chile in 2025 and 2024 was 27%.

(1)Net interest margin is net interest income divided by average interest-earning assets.

For the nine months ended September 30, 2025, our net interest income totaled Ch$1,512,487 million and increased 16.6% compared to the same period in 2024. Average interest earning assets decreased 2.6% in the same period as the Bank used liquid financial investments to pay the Central Bank's FCIC that came due in 2024 and also due to a slight contraction in the mortgage loan book.

The average nominal interest rate earned on interest earning assets decreased from 5.8% in the nine months ended September 30, 2024 to 5.5% in the same period in 2025. This was mainly due to: (i) lower yields earned over interest earning assets due to the lower interest rate environment as well as lower yields earned over interest earning assets denominated in UF due to the slightly lower UF inflation rate in the nine months ended September 30, 2025 compared to the same period in 2024. This fall in asset yields was partially offset by a decrease in lower yielding commercial loans and financial investments in the year compared to the rise in higher yielding consumer loans.

|:---|:---|:---|
| **Average nominal interest rate earned on interest earning assets** | **2025** | **2024** |
| Ch$ | 8.5% | 6.1% |
| UF | 3.6% | 5.8% |
| Foreign currencies | 4.1% | 4.6% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Total** | **5.5%** | **5.8%** |

---

The fall in short-term interest rates and the lower UF inflation also lowered funding costs in the nine months ended September 30, 2025 compared to the same period in 2024. The average rate paid on our interest-bearing liabilities decreased from 4.8% in nine months ended September 30, 2024 to 3.8% in the same period in 2025. Our interest-bearing liabilities have a shorter maturity than our interest-earning assets and, therefore, incorporate rate cuts more quickly. The most important reduction in funding costs came from the lower rate paid on interest bearing time deposits, the Bank's main source of funding, which fell from 4.5% in nine months ended September 30, 2024 to 3.5% in the same period in 2025. The funding mix also improved in nine months ended September 30, 2025 as the ratio of average equity and non-interest

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

bearing demand deposits to total average interest earning assets improved from 32.5% in nine months ended September 30, 2024 to 33.6% in the same period in 2025.

|:---|:---|:---|
| **Average nominal interest rate paid on interest bearing liabilities** | **2025** | **2024** |

| Foreign currencies | 2.0% | 2.1% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Total** | **3.8%** | **4.8%** |

---

In summary, the improved asset and funding mix and the impact of lower rates on funding more than offset the impact of lower inflation and rates on interest earning assets, which drove our net interest margin to increase from 3.24% in nine months ended September 30, 2024 to 3.86% in nine months ended September 30, 2025.

The following table shows interest income of financial assets by valuation as of September 30, 2025 and 2024. The 5.7% decrease is mainly due to the reduction in financial investments in 2025 compared to 2024 and the lower variation of the UF, which had a negative impact on commercial and mortgage loans denominated in this unit partially.

(1)Financial assets measured at amortized cost include loans measured at amortized cost as described above and investments under resale agreements. The effective interest method is used in the calculation of the amortized cost of the financial asset and in the allocation and recognition of the interest revenue over the relevant period.

(2)Financial assets measured at fair value through other comprehensive income include the interest income from debt instruments. These mainly consisted of securities and bonds of the Central Bank that contain contractual terms that give rise on specific dates to cash flows that are solely payments of principal and interest (SPPI), and are measured at FVOCI.

***Fee and Commission Income***

Net fees and commission income increased 8.0% to Ch$441,142 million in the nine months ended September 30, 2025 compared to the same period in 2024. Fee growth in 2025 continued to be driven by client growth, improved cross-selling indicators, and greater availability and usage of our digital platforms.

Fees from card services increased 15.0% in the nine months ended September 30, 2025, compared to the same period of 2024. This marked increase is mainly due to the increased use of our credit card by our customers, which was in turn driven by the growth of our customer base, reflecting the success of our strategy.

Fees from Getnet, the Bank's subsidiary in the acquiring business, increased 40.8% in the nine months ended September 30, 2025, compared to same period of 2024. This was driven by strong growth in the number of SME customers of Getnet and greater usage of cards for payments in Chile. Furthermore, as a result of the development of more sophisticated and integrated solutions, Getnet is now attracting larger retailers with national coverage. As of September 30, 2025 we had over 312,000 Getnet POS in operation.

Fees from the brokerage of mutual funds increased 22.7% in the nine months ended September 30, 2025, compared to the same period in 2024. This increase was driven by customer demand for investment products in the context of the low-rate cycle and lower preference for time deposits as well as by the expansion of the customer base in previous periods.

Fees from management of accounts increased 10.1% in the nine months ended September 30, 2025, compared to the same period in 2024. Growth in account openings continued during the quarter. This brings the Bank's market share of total checking accounts to 22.1% as of August 2025 (the latest date as of which data is available). This also reflects a strong increase in customer demand for U.S. dollar-denominated checking accounts, as customers can open such accounts digitally through our online banking platform in a few easy steps. We have opened 91,000 accounts in the last 12 months (through August 2025) to reach a total of 525,721 U.S. dollar-denominated checking accounts, achieving a total market share of 39.6%.

Fees from collections and payments decreased 1.7% in the nine months ended September 30, 2025, compared to the same period in 2024 due to lower collection fees for credit and insurance-related items.

Insurance brokerage fees decreased 13.7% in the nine months ended September 30, 2025, compared to the same period in 2024 due to lower commissions generated by personal insurance, including mostly mortgage insurance and, to a

lesser extent, consumer insurance. This performance is consistent with an observed decrease in demand for retail loans compared to nine months ended September 30, 2024.

Fees from guarantees and letters of credit increased 23.3% in the nine months ended September 30, 2025, compared to the same period in 2024. This line item corresponds to international and foreign trade financing business with clients. The increase was mainly due to higher fees from our corporate and large enterprise customers, particularly related to Stand-by letters of credit.

Fees from financial advisory decreased by 37.4% in the nine months ended September 30, 2025, compared to the same period in 2024. Our Middle-Market segments experienced an important increase in large advisory deals in 2024 and this dynamic has continued positively in 2025.

Fees from office banking, the Bank's online digital banking platform for companies, increased 3.1% in the nine months ended September 30, 2025, compared to the same period in 2024. The increase is explained by the expansion of our online services for our corporate, middle-market and SME customers.

Fees from the prepayment of loans decreased by 0.5% in the nine months ended September 30, 2025, compared to the same period in 2024 mainly due to lower prepayments in mortgage and consumer loans. The evolution of loan prepayment fees is related to the interest rate cycle, when interest rates fall, there is more demand to prepay loans. Given the decrease in rates in recent years, and only a small decrease in rates in 2025 so far, demand for prepayments of loans has been lower in the nine months ended September 30, 2025.

The 41.2% increase in the loss from other fee income in the nine months ended September 30, 2025, compared to the same period in 2024, was mainly due to higher fee expenses from our corporate and middle-market customers.

Net income from financial operations amounted to Ch$215,367 million for the nine months ended September 30, 2025, an increase of 19.3% compared to the same period of 2024. These results include the results of our Treasury Division's trading business and financial transactions with customers, as well as the results of our Financial Management Division. The higher result was mainly due to a higher gain on the trading portfolio and a gain on the available-for-sale portfolio compared to a loss last year which was partially offset by lower results from the foreign currency position and the valuation of derivative contracts in the period.

Net income from financial assets and liabilities for trading at fair value through the profit and loss statement totaled a gain of Ch$76,438 million in the nine months ended September 30, 2025 and compared to a loss in the same period in 2024. This increase was mainly due to higher results from derivative contracts accounted under this method.

Net income from derecognizing financial assets and liabilities at amortized cost and financial assets at fair value through other comprehensive income totaled a gain of Ch$2,024 million in the nine months ended September 30, 2025 compared to a loss of Ch$40,713 million in the same period in 2024. This result mainly corresponds to our Financial

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

Management Division. In 2024 this division derecognized fixed income instruments in its portfolio, which is mainly comprised of Chilean Central Bank bonds. Since long-term rates have reduced from previous levels and moved closer to purchase yields, this derecognition has resulted in a gain in this line item during 2025.

Net income from exchange, adjustment and hedge accounting of foreign exchange totaled Ch$136,905 million in the nine months ended September 30, 2025, a decrease of 38.6% compared to the gain obtained in the same period of 2024. Internal Bank policy does not allow significant foreign currency mismatches and requires that the results registered in Net income from financial operations include not only the market-to-market of our foreign currency spot position, but also the results of the derivatives used to hedge currency risk and currency exchange services. The mark-to-market of our spot position and the derivatives used to hedge foreign currency risk are classified in the line item: Net income from exchange, adjustment and hedge accounting of foreign exchange. For more details regarding our management and exposure to foreign currency risk, see "Item 11. Quantitative and Qualitative Disclosures About Market Risk—E. Market Risks—Market risk management—Market risk – local and foreign financial management." of our 2024 20-F.

This lower result from exchange, adjustment and hedge accounting of foreign exchange was mainly due to lower net income from foreign currency exchange. The Chilean peso appreciated 3.3% in nine months ended September 30, 2025 and depreciated 4.3% in the same period of 2024 against the U.S. dollar. The Bank generally has more liabilities than assets in its spot position, since the amount of long-term funding and deposits in dollars tends to be greater than loans and financial investments in this currency. Therefore, the results from Net income from foreign currency exchange included in this line item reflect the impact on the Bank's profit and loss statement of the movements in the exchange rate of the non-hedged portion of the balance sheet. For more information please see "Note 33-Net Income (Expenses) from Financial Operations-Net income from exchange, adjustment and hedge accounting of foreign currency" of the Consolidated Balance Sheet.

In order to more easily compare the results from net income from financial operations, we present the following table that separates the results by lines of business for the nine months ended September 30, 2025 and 2024.

(1)The Financial Management Division manages the structural interest rate risk, the structural position in inflation-indexed assets and liabilities, capital requirements and liquidity levels. The aim of the Financial Management Division is to provide stability and continuity in our net interest income from commercial activities, and to ensure that we comply with internal and regulatory limits regarding liquidity, regulatory capital, reserve requirements and market risk.

Income from client treasury services totaled Ch$195,836 million, a decrease of 6.6% compared to the same period of 2024. The results from client treasury products and market-making mainly include the results from the sale of derivatives, foreign exchange and fixed income instruments to our client base. For the nine months ended September 30, 2025, the decrease is explained by exchange rate effects and offset by a strong performance from the trading strategy. These results may vary year-to-year as some large operations with corporate clients may not be repeated in subsequent years and market condition vary each year.

The results from non-client treasury income totaled a gain of Ch$19,531 million in the nine months ended September 30, 2025. These results include the income from sale of loans, including charged-off loans, CVA adjustments and most importantly, the treasury results from our Financial Management Division.

of Ch$7,854 million in the same period of 2024. During the nine months ended September 30, 2025, the Bank carried out various liability management exercises including the higher portfolio sales and offset by the repurchase of bonds.

The results from the sale of loans totaled a gain of Ch$2,644 million in the nine months ended September 30, 2025 compared to Ch$331 million in the same period of 2024. The results from CVA adjustment improved from a loss of Ch$21,715 million in 2024 to a gain of Ch$12,803 million in 2025 due to an improvement in the credit risk of the Bank's counterparties in derivative transactions.

Other Operating Income, Income from investments in associates and other companies and Net income from non-current assets and non-continued operations decreased by 15.0% in the nine months ended September 30, 2025 compared to the same period in 2024.

Income from investments in associates and other companies increased 5.9% in the nine months ended September 30, 2025 due to higher income generated from our associated companies.

Net income from non-current assets and non-continued operations presented a lower loss of 77.0% in the period mainly due to higher income from repossessed assets and higher expenses for maintenance of assets received in lieu of payment.

Other operating income decreased 67.8% in the nine months ended September 30, 2025 due to lower income received for other services such as rental income from subsidiaries.

***Operating Expenses***

The following table sets forth information regarding our operating expenses in the nine months ended September 30, 2025 and 2024.

---

| | | | |
|:---|:---|:---|:---|
| | **Nine months ended September 30,** | **Nine months ended September 30,** | **% Change** |
| | **2025** | **2024** | **2025/2024** |
| | **(in millions of Ch$)** | **(in millions of Ch$)** | |
| Personnel salaries and expenses | (307995) | (298388) | 3.2% |
| Administrative expenses | (301308) | (276019) | 9.2% |
| Depreciation and amortization | (101150) | (105712) | (4.3%) |
| Impairment of property, plant and equipment | (2924) |  | 100.0% |
| Other operating expenses | (67789) | (77446) | (12.5)% |
| **Total operating expenses** | **(781166)** | **(757565)** | **3.1%** |
| Efficiency ratio<sup>(1)</sup> | 35.9% | 40.0% |  |

---

(1)The efficiency ratio is the ratio of total operating expenses to total operating income. Total operating income consists of net interest income, fee income, net income from financial operations, and other operating income.

Operating expenses in the nine months ended September 30, 2025 increased 3.1% compared to the corresponding period in 2024 mainly due to an increase in administrative expenses, which was partially offset by a decrease in other operating expense. The efficiency ratio improved to 35.9% in 2025 compared to 40.0% in 2024, reflecting the strong increase in revenues in the year.

Personnel salaries and expenses in the nine months ended September 30, 2025 increased 3.2% compared to the corresponding period in 2024, mainly due to adjustment of salaries for inflation and higher severance expenses and compensated in part by the 3.1% decrease in headcount during the period.

Administrative expenses increased 9.2% in the nine months ended September 30, 2025 compared to the corresponding period in 2024 due to higher technology and data processing expenses, largely related to the Gravity project. In early 2025, the Bank celebrated the main milestone of the Gravity project, its migration from the mainframe servers to a cloud-based server. In January 2025, we transitioned processing to our new cloud-based server, which resulted in higher expenses related to the changeover and write-downs and impairment recognition related to legacy systems.

This increase was partially offset by reductions in the Bank's branch network. As of September 30, 2025, the Bank had a total of 231 branches, 94 of which were in the efficient WorkCafé or Workcafé Expresso format. The table below provides a breakdown of the Bank's branch network during the periods indicated.

| **Total ATMs (including depositary ATMs)** | **2063** | **2072** | **(0.4** **%)** |

---

Depreciation and amortization expense decreased 4.3% in 2025 compared to the nine months ended September 30, 2024 mainly due to lower amortization of internally generated software used for the development of our digital platforms.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

The impairment expense reached Ch$2,924 million in the nine months ended September 30, 2025 an impairment was recognized related to the software development.

Other operating expenses decreased 12.5% in the nine months ended September 30, 2025 compared to the same period in 2024. This decrease mainly corresponds to restructuring charges due to the on-going restructuring of our branch network and other digital transformations incurred in the nine months ended September 30, 2024 as well as greater expenses of insurance premiums related to operating risk such as fraud insurance, all of which have not been repeated in the nine months ended September 30, 2025 to the same extent.

See "Note 36—Other Operating Income and Expenses" to our Unaudited Interim Consolidated Financial Statements for more detail on Other operating expenses.

***Provision for loan losses (P&L)***

For the nine months ended nine months ended September 30, 2025, provisions for loan losses totaled Ch$430,389 million and increased 9.4% compared to 2024. This increase was mainly due to a rise of risk in the commercial and mortgage loans. This trend was partially offset by a 30.3% rise in recoveries of loans previously charged-off. The table below breaks down these results by main product item:

---

| | | | |
|:---|:---|:---|:---|

---

Provisions for loan losses of our commercial loans totaled Ch$149,151 million for the nine months ended September 30, 2025 and increased 12.5% compared to 2024. In commercial loans, deterioration of asset quality was mainly concentrated in the real estate due to the high interest environment of previous years and in agriculture, where companies were impacted by adverse weather conditions in recent years.

Provisions for mortgage loans totaled Ch$25,672 million for the nine months ended September 30, 2025, a significant increase compared to the same period of 2024. This was mainly due to a release of provisions in mortgage loans in the third quarter of 2024 due to higher restructurings and recoveries, which was not repeated in 2025.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

Provisions for consumer loans totaled Ch$255,567 million for the nine months ended September 30, 2025, a decrease of 0.1% compared to the same period in 2024. In January 2025, the FMC implemented a regulatory change to the consumer provisioning model, for which we used additional provisions to cover the initial impact of $94 billion, explaining the reversal in special provisions for credit risk.

Recoveries on loans previously charged-off increased 30.3% in the nine months ended September 30, 2025 compared to the same period 2024 as the Bank has improved efforts to recover loans previously charged-off. The following table shows recoveries of loans previously charged-off by type of loan.

***Income tax***

| Net operating income before income tax | 965649 | 744946 | 29.6% |
| Income tax expense | (156229) | (154136) | 1.4% |
| **Effective tax rate(1)** | **16.2%** | **20.7%** |  |

---

(1)The effective tax rate is the income tax expense divided by net operating income before income tax.

Total income tax expense by the Bank in the nine months ended September 30, 2025 was Ch$156,229 million, an increase of 1.4% compared to the same period in 2024. Net operating income before income tax increased 29.6%. The Bank paid an effective tax rate of 16.2% in the nine months ended September 30, 2025 compared to 20.7% in the nine months ended September 30 2024. The statutory corporate tax rate in Chile in 2024 and 2025 was 27%. The Bank usually pays a lower effective tax rate than the statutory rate since in our Chilean tax books we must re-measure capital each year for the variation in CPI inflation and this produces a tax loss. The rise in income tax expenses in the nine months ended September 30, 2025 compared to the same period in 2024 was mainly due to the increase in pre-tax income and a lower origination of temporary tax differences in the period. See "Note 18—Current and Deferred Taxes" of the Unaudited Interim Consolidated Financial Statements for more detail on income tax expense.

(1)Includes demand deposits and other demand liabilities, cash items in process of being cleared and time deposits and other time liabilities.

(2)Mainly includes amounts owed to credit card processors and to the Chilean Production Development Corporation (*Corporación de Fomento de la Producción de Chile*), the state development agency.

(3)The table above includes future cash interest payments. For variable rate obligations, we assume the same rate as the last rate known. Various of the payment obligations in the table above are variable debt instruments, since they are denominated in UF, for which we have estimated a long-term inflation rate equal to 3%, which is at the center of the Central Bank's long-term inflation target. No exclusions requiring further explanation have been made in this table.

The Bank has checking accounts, time deposits and other time liabilities maturing within one year amounting to Ch$30,619,579 million as of September 30, 2025. Santander-Chile's liquidity depends upon its (i) capital, (ii) reserves and (iii) financial investments, including investments in government securities. To cover any liquidity shortfalls and to augment its liquidity position, Santander-Chile has established lines of credit with foreign and domestic banks and also has access to Central Bank borrowings. The Bank has a liquidity portfolio of Ch$7,311,310 million as of September 30, 2025, including cash and liquid assets defined by the Bank's Asset and Liability Committee (ALCO) in line with BIS III guidelines.

For further discussion of the maturities of our liquid assets, see "Analysis of Investments". Our general policy is to maintain adequate liquidity to ensure our ability to honor withdrawals of deposits, make repayments of other liabilities at maturity, extend loans and meet our own working capital needs. Our minimum amount of liquidity is determined by the statutory reserve requirements of the Central Bank.

Most instruments maturing after one year are financial derivative contracts and issued debt instruments. Our current funding strategy is to continue to utilize all sources of funding in accordance with their costs, their availability and our general asset and liability management strategy. Special emphasis is placed on lengthening the maturities of funding with institutional clients, diversifying our bondholder base. Overall, the management of our liquidity and funding has led to an LCR ratio of 164.7% and a NSFR of 111.0% as of September 30, 2025. Furthermore, the Bank also has regulatory capital of Ch$7,085,778 million, representing 16.66% of our risk-weighted assets as of September 30, 2025.

**Capital requirements**

Regulatory capital and core capital are calculated based on consolidated financial statements prepared in accordance with the FMC standards (Compendium of Accounting Standards).

On April 1, 2025, the FMC reported on the annual classification of systemically important banks. In this communication, the FMC Council approved Resolution No. 3,143 regarding this classification, thereby maintaining, for one more year, the requirement for an additional 1.5% Common Equity Tier 1 capital surcharge for the Bank.

On April 11, 2025, the FMC issued Exempt Resolution No. 3,612 regarding the application of additional capital requirements under Pillar II, in which the FMC Council decided to apply additional capital requirements of 0.25%, 50% of which the Bank applied in June 2025.

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

We are currently required to maintain a minimum regulatory capital to risk-weighted assets ratio of 12.13%. To date the Bank presents a minimum regulatory capital to risk-weighted assets ratio of 17.06%.

**Financial Investments**

On initial recognition, financial assets and financial liabilities are measured at the transaction price, i.e. the fair value of the consideration given or received (IFRS 13). In the case of financial instruments not at fair value through profit or loss, transaction costs are directly attributable to the acquisition or issue of the financial asset or financial liability. After initial recognition, an entity shall measure a financial liability at amortized cost and an entity shall measure a financial asset at:

&nbsp;&nbsp;&nbsp;&nbsp;***(a)Amortized Cost***

Financial assets that are held in a business model to collect the contractual cash flows and contain contractual terms that give rise on specific dates to cash flows that are SPPI, are measured at amortized cost.

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

The effective interest method is used in the calculation of the amortized cost of a financial asset or a financial liability and in the allocation and recognition of the interest revenue or interest expense in profit or loss over the relevant period. The effective interest rate ("EIR") is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial asset or financial liability to the gross carrying amount of a financial asset or to the amortized cost of a financial liability.

*Debt financial instruments at amortized cost*

These instruments include high rated loans and Central Bank bonds and notes.

&nbsp;&nbsp;&nbsp;&nbsp;***(b)Fair Value through Other Comprehensive Income (FVOCI)***

Financial assets that are debt instruments held in a business model that is achieved by both collecting contractual cash flow and selling, and that contain contractual terms that give rise on specific dates to cash flows that are SPPI, are measured at FVOCI. They are subsequently remeasured at fair value and changes therein (except for those relating to impairment, interest income and foreign currency exchange gains and losses) are recognized in other comprehensive income, until the assets are sold. Upon disposal, the cumulative gain and losses in OCI are recognized in the income statement.

**Working Capital**

As a bank, we satisfy our working capital needs through general funding, the majority of which derives from deposits and other borrowings from the public. (See "Item 2. Operating and Financial Review and Prospects—D. Liquidity and Capital Resources—Deposits and Other Borrowings"). In our opinion, our working capital is sufficient for our present needs.

**Liquidity Management**

Liquidity management seeks to ensure that, even under adverse conditions, we have access to the funds necessary to cover client needs, maturing liabilities and capital requirements. Liquidity risk arises in the general funding for our financing, trading and investment activities. It includes the risk of unexpected increases in the cost of funding the portfolio of assets at appropriate maturities and rates, the risk of being unable to liquidate a position in a timely manner at a reasonable price and the risk that we will be required to repay liabilities earlier than anticipated.

The following table sets forth the balance of our liquidity portfolio managed by our Financial Management Division in the manner in which it is presented to the Asset and Liability Committee (ALCO) and the Board. The ALCO now uses as

------

its liquidity portfolio those defined by the FMC and the Central Bank, which are in line with those established in BIS III. As of September 30, 2025 and 2024, the breakdown of the Bank's liquid assets by levels was the following:

Our general policy is to maintain liquidity adequate to ensure our ability to honor withdrawals of deposits, make repayments of other liabilities at maturity, extend loans and meet our own working capital needs. Our minimum amount of liquidity is determined by the statutory reserve requirements of the Central Bank. Deposits are subject to a statutory reserve requirement of 9.0% for demand deposits and 3.6% for Chilean peso-, UF- and foreign currency denominated time deposits with a term of less than a year. See "Item 4. Information on the Company—B. Business Overview—Competition—Regulation and Supervision" of our 2024 20-F. The Central Bank has statutory authority to increase these percentages to up to 40.0% for demand deposits and up to 20.0% for time deposits. In addition, a 100% special reserve (*reserva técnica*) applies to demand deposits, deposits in checking accounts, other demand deposits received or obligations payable on sight and incurred in the ordinary course of business, other than deposits unconditionally payable immediately. This special reserve requirement applies to the amount by which the total of such deposits exceeds 2.5 times the amount of a bank's regulatory capital. Interbank loans are deemed to have a maturity of more than 30 days, even if payable within the following 10 days. The Central Bank has also set other liquidity limits and ratios that minimize liquidity risk. See "Item 4. Quantitative and Qualitative Disclosures About Market Risk."

**Cash Flow**

The tables below set forth our main sources of cash. The subsidiaries are not an important source of cash flow for us and therefore have no impact on our ability to meet our cash obligations. No legal or economic restrictions exist on the ability of subsidiaries to transfer funds to us in the form of loans or cash dividends as long as these subsidiaries abide by the regulations of the General Banking Law (*Ley General de Bancos)* and the Chilean Corporations Law *(Ley de Sociedad Anónimas)* regarding loans to related parties and minimum dividend payments. See our Consolidated Statements of Cash Flows in our Unaudited Interim Consolidated Financial Statements for a detailed breakdown of the Bank's cash flow.

| Net cash flow (used in) provided by operating activities | 421044 | 207671 |

---

Our operating activities provided cash in an amount of Ch$421,044 million in the nine months ended September 30, 2025, mainly due to an increase in profits and greater repurchase contracts (liabilities), which was partially offset by a reduction in cash disbursed for loans and lower deposit volumes. Our operating activities provided cash for Ch$207,671 million in the nine months ended September 30, 2024, mainly due to a decrease in financial investments (Central Bank instruments) and offset by the payment of the FCIC obligation with the Central Bank of Chile.

In the nine months ended September 30, 2025 and 2024 the Bank's investment activities consumed cash in an amount of Ch$56,828 million, mainly due to the purchase of property, plant and equipment, which was mainly related to investments in the Workcafé branch network. Cash was also consumed by investments in intangible assets, such as software, mainly related to the Bank's digital strategy.

| Net cash provided by (used in) financing activities | (1069518) | (930051) |

---

In the nine months ended September 30, 2025, net cash used in financing activities was Ch$1,069,518 million and was mainly due to the payment of the annual dividend paid to shareholders in April 2025, which was higher than the dividend paid in 2024. Additionally in January 2025, the Bank repaid the aggregate principal amount and accrued interest of its 2.70% notes due 2025 in an amount of U.S.$704 million (Ch$677,129 million). This was partially offset by the placement of other senior bonds in the period. In the nine months ended September 30, 2024, net cash used in financing activities was Ch$930,051 million due to the annual dividend payment and the payment of senior bonds, compensated in part by the placement of new bonds in the period.

---

Our most important source of funding is our deposits. Average time deposits plus non-interest bearing demand deposits represented 44.0% of our average total liabilities and shareholders' equity as of September 30, 2025. As of September 30, 2025, the Bank's top 20 time deposits represented 26.2% of total time deposits, or 6.2% of total liabilities and equity. Our current funding strategy is to continue to utilize all sources of funding in accordance with their costs, their availability and our general asset and liability management strategy. Special emphasis is being placed on lengthening the maturities of funding with institutional clients, diversifying our bond holder base and broadening our core deposit funding. We believe that broadening our deposit base by increasing the number of account holders has created a more stable funding source.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(a)****Loans from Central Bank*

In response to the COVID-19 pandemic, the Central Bank made two lines of credit available to banks to reinforce their liquidity and to fund loans for SMEs with government guarantees. These lines of credit had an interest equal to the Central Bank's monetary policy rate (MPR), which was 0.5% at the time the lines of credit were granted. These lines of credit were paid in full during 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(b)Mortgage finance bonds*

These bonds are used to finance mortgage loans. Their principal amounts are amortized on a quarterly basis. The range of maturities of these bonds is between five and twenty years. Loans are indexed to UF and pay a yearly interest rate.

***Other Off-Balance Sheet Arrangements and Commitments***

In the normal course of our business, we are party to transactions with off-balance sheet risk. These transactions expose us to credit risk in addition to amounts recognized in the consolidated financial statements. The most important off-balance sheet item is contingent loans. Contingent loans consist of guarantees granted by us in Ch$, UF and foreign currencies (principally U.S.$), unused letters of credit and commitments to extend credit such as overdraft protection and credit card lines of credit. Such commitments are agreements to lend to a customer at a future date, subject to the customer compliance with the contractual terms. Since a substantial portion of these commitments is expected to expire without being drawn upon, the total amount of commitments does not necessarily represent our actual future cash requirements. We use the same credit policies in making commitments to extend credit as we do for granting loans, therefore, in the opinion of our management, our outstanding commitments represent normal credit risk.

The following table presents the Bank's outstanding contingent loans as of September 30, 2025 and December 31, 2024:

(1)Includes assets ceded under operating leases.

During 2025, the Bank continues to focus its investments in its ongoing digital transformation and expanding the Workcafé network. This involved new investments, especially in systems while producing savings in the physical branch network (land and buildings) and other fixed assets such as furniture, vehicles, among others.

**E.Selected Statistical Information**

The following information is included for analytical purposes and should be read in conjunction with our Audited Consolidated Financial Statements, as well as the discussion in this "Item 2. Operating and Financial Review and Prospects." The UF is linked to, and is adjusted daily to reflect changes in, the previous month's Chilean consumer price index. See "Item 2. Operating and Financial Review and Prospects—C. Operating Results—Impact of Inflation."

**Average Balances, Income Earned from Interest-Earning Assets and Interest Paid on Interest-Bearing Liabilities**

The average balances for interest-earning assets and interest-bearing liabilities, including interest and readjustments received and paid, have been calculated on the basis of daily balances for us on an unconsolidated basis. Such average balances are presented in Chilean pesos, UFs and in foreign currencies (principally U.S. dollars). Figures from our subsidiaries have been calculated on the basis of monthly balances. The average balances of our subsidiaries, except Sociedad Operadora de Tarjetas de Pago Santander Getnet Chile S.A., have not been categorized by currency. As such it is not possible to calculate average balances by currency for such subsidiaries on the basis of daily, weekly or monthly balances.

The nominal interest rate has been calculated by dividing the amount of interest and principal changes in the UF index (gain or loss) during the period by the related average balance, both amounts expressed in constant Chilean pesos.

The Bank has also distributed the financial cost or gain of hedges to the corresponding item being hedged to more clearly reflect the impact of these hedging strategies on yields earned or paid over assets and liabilities. For this reason, total interest earned over interest earning assets and interest paid over interest bearing liabilities can be different from the amounts recorded in the income statement, but the net interest income is equivalent to the amount recorded in the income statement. Foreign exchange gains or losses on foreign currency-denominated assets and liabilities are not included in interest income or expense. When a financial asset becomes credit-impaired and is, therefore, regarded as "Stage 3", the Bank suspends the interest income recognition in the income statement. Similarly, trading and mark-to-market gains or losses on investments are not included in interest income or expense. Interest is not recognized on non-performing loans. Non-performing loans that are past-due for 90 days or less have been included in each of the various categories of loans, and therefore affect the various averages. Non-performing loans consist of loans as to which either principal or interest is past-due (*i.e.*, non-accrual loans) and restructured loans earning no interest.

Included in interbank deposits are checking accounts maintained in the Central Bank and foreign banks. Such assets have a distorting effect on the average interest rate earned on total interest-earning assets because currently balances maintained in Chilean peso amounts do not earn interest, and the only balances held in a foreign currency that earn interest are those maintained in U.S. dollars, but those only earn interest on the amounts that are legally required to be held for liquidity purposes. Additionally, this account includes interest earned by overnight investments. Consequently, the average interest earned on such assets is comparatively low. We maintain these deposits in these accounts to comply with statutory requirements and to facilitate international business, rather than to earn income. See Note 2—Summary of Significant Accounting Policies—(k) Recognizing Income and Expenses to our Unaudited Interim Consolidated Financial Statements.

The following tables show, by currency of denomination, average balances and, where applicable, interest amounts and real rates for our assets and liabilities for the nine months ended September 30, 2025 and 2024.

***Changes in Net Interest Revenue and Interest Expense: Volume and Rate Analysis***

The following table allocates, by currency of denomination, changes in our net interest revenue and interest expense between changes in the average volume of interest-earning assets and interest-bearing liabilities and changes in their respective nominal interest rates for the nine months ended September 30, 2025 compared to the same period in 2024. Volume and rate variances have been calculated based on movements in average balances over the period and changes in nominal interest rates on average interest-earning assets and average interest-bearing liabilities.

**Loan Portfolio**

***Loan Categories***

Our loan categories are as follows:

*Interbank loans*

<u>Interbank loans</u> are long-term and short-term loans made to other local or international banks, granted in Chilean pesos or foreign currencies, usually at a variable rate linked to Chilean interbank rates, SOFR or other interbank rates.

*Commercial loans*

<u>Commercial loans</u> are long-term and short-term loans, including checking overdraft lines for companies, granted in Chilean pesos, inflation linked, U.S.$ linked or denominated in U.S.$. The interest on these loans is fixed or variable and is used primarily to finance working capital or investments. General commercial loans also include factoring operations.

<u>Foreign trade loans</u> are fixed rate, short-term loans made in foreign currencies (principally U.S.$) to finance imports and exports.

<u>Checking account debtors</u> are checking overdraft lines granted to companies, in Chilean pesos or U.S.$, generally on a fixed rate nominal basis and linked to a company's checking account.

<u>Credit card debtors</u> includes credit card balances from businesses subject to nominal fixed rate interest charges.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

<u>Factoring transactions</u> mainly include short-term loans to companies with a fixed monthly nominal rate backed by a company invoice.

<u>Leasing transactions</u> are agreements for the financial leasing of capital equipment and other property.

<u>Student loans</u> mainly include long-term loans made to finance tertiary education mainly in fixed real rates (UF) some of which some are guaranteed by the state. These loans, per Chilean regulations, must be classified as commercial loans since they are guaranteed by the Chilean State under Law 20,027 through CORFO, the government's development agency.

<u>Other loans and accounts receivable loans</u> include other commercial loans and accounts payable not included in any of the categories above.

*Mortgage loans*

<u>Loans with mortgage finance bonds</u> are inflation-indexed, fixed or variable rate, long-term loans with monthly payments of principal and interest secured by a real property mortgage that are financed with mortgage finance bonds as defined in Chapter 9-1 of the FMC Updated Compilation of Banking Regulations (Recopilación Actualizada de Normas or RAN). At the time of approval, these types of mortgage loans cannot be more than 75.0% of the lower of the purchase price or the appraised value of the mortgaged property or such loan will be classified as a commercial loan. Mortgage bonds are our general obligations, and we are liable for all principal and accrued interest on such bonds. In addition, if the issuer of a mortgage finance bond becomes insolvent, the General Banking Law's liquidation procedures provide that these types of mortgage loans with their corresponding mortgage bonds shall be auctioned as a unit and the acquirer must continue paying the mortgage finance bonds under the same conditions as the original issuer.

<u>Endorsable mortgage mutual loans</u> are inflation-indexed fixed rate or variable rate, long-term loans with monthly payment of principal and interest secured by a real property mortgage that are financed through general funding. These kinds of loans are supported by a contract deed, which can be sold in the market through an endorsement.

<u>Mortgage mutual financed with mortgage bond</u> includes mortgage loans (fixed and variable rate) that are inflation-indexed long-term loans with monthly payments of principal and interest secured by a real property mortgage. These are financed by issuing mortgage bonds as defined in Chapter 9-2 of Chilean banking regulations.

<u>Other mortgage mutual loans</u> mainly include mortgage loans (fixed and variable rate) that are inflation-indexed long-term loans with monthly payments of principal and interest secured by a real property mortgage. These are financed by our general borrowings.

<u>Other loans and accounts receivable loans</u> include other mortgage loans and accounts payable not included in any of the categories above.

*Consumer loans*

<u>Installment consumer loans</u> are loans to individuals, granted in Chilean pesos, generally on a fixed rate nominal basis, to finance the purchase of consumer goods or to pay for services. This includes auto loans originated through Santander Consumer Chile.

<u>Checking account debtors</u> are checking overdraft lines to individuals, granted in Chilean pesos, generally on a fixed rate nominal basis and linked to an individual's checking account.

<u>Credit card debtors</u> include credit card balances subject to nominal fixed rate interest charges.

<u>Leasing transactions</u> are agreements for the financial leasing of automobiles and other property to individuals.

<u>Other consumer loans</u> are other loans to individuals that are not classified in any of the other categories shown above.

**ITEM 4. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

**Introduction**

The principal types of risk inherent in Santander-Chile's business are market, liquidity, operational and credit risks. The effectiveness with which we are able to manage the balance between risk and reward is a significant factor in our ability to generate long term, stable earnings growth. Toward that end, our Board and senior management places great emphasis on risk management.

For more information on our Integral Risk Committee, Audit Committee, Asset and Liability Committee and Market Committee, see "Item 6. Directors, Senior Management and Employees."

**Market Risk: Qualitative Disclosure**

For qualitative disclosure regarding risk management please refer to Item 11 of our 2024 20-F. These policies and procedures remain in effect throughout 2025 and as of the date of this Report.

**Market Risk: Quantitative Disclosure**

***Impact of Inflation***

Our assets and liabilities are denominated in Chilean pesos, Unidades de Fomento (UF) and foreign currencies. Inflation impacts our results of operations as some loan and deposit products are contracted in UF. The UF is revalued in monthly cycles. Each day in the period beginning on the tenth day of the current month through the ninth day of the succeeding month, the nominal peso value of the UF is indexed up (or down in the event of deflation) in order to reflect a proportionate amount of the change in the Chilean Consumer Price Index during the prior calendar month. One UF equaled Ch$39,485.65 as of September 30, 2025 and Ch$38,416.69 as of December 31, 2024, presenting a UF variation of 2.8% in the nine months ended September 30, 2025. High levels of inflation in Chile could adversely affect the Chilean economy and could have an adverse effect on our business, financial condition, and results of operations. Negative inflation rates also negatively impact on our results. There can be no assurance that Chilean inflation will not change significantly from the current level.

Due to the current structure of our assets and liabilities (i.e., a significant portion of our loans are indexed to the inflation rate, but there are significantly less features in deposits and other funding sources that would increase the size of

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

our funding base), there can be no assurance that our business, financial condition and result of operations in the future will not be adversely affected by changing levels of inflation. In summary:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *UF-denominated assets and liabilities.* The effect of any changes in the nominal peso value of our UF-denominated interest earning assets and interest-bearing liabilities is reflected in our results of operations as an increase (or decrease, in the event of deflation) in interest income and expense, respectively. Our net interest income will be positively affected by an inflationary environment to the extent that our average UF-denominated interest earning assets exceed our average UF-denominated interest-bearing liabilities. Our net interest income will be positively affected by deflation in any period in which our average UF-denominated interest-bearing liabilities exceed our average UF-denominated interest earning assets. Our net interest income will be negatively affected in a deflationary environment if our average UF-denominated interest earning assets exceed our average UF-denominated interest-bearing liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Inflation and interest rate hedge.* A key component of our asset and liability policy is the management of interest rate risk. The Bank's assets generally have a longer maturity than our liabilities. As the Bank's mortgage portfolio grows, the maturity gap tends to rise as these loans, which are contracted in UF, have a longer maturity than the average maturity of our funding base. As most of our long-term financial instruments and mortgage loans are contracted in UF and most of our deposits are in nominal pesos, the rise in mortgage lending increases the Bank's exposure to inflation and to interest rate risk. This gap's size is limited by internal and regulatory guidelines to avoid excessive potential losses due to strong shifts in interest rates or inflation. To keep this duration gap below internal and regulatory limits, the Bank issues long term bonds denominated in UF or interest rate swaps. The financial cost of the bonds and the efficient part of these hedges is recorded as net interest income. The loss from the swaps taken to hedge mainly for inflation and interest rate risk, and included in net interest income, totaled a loss of Ch$216,163 million in the nine months ended September 30, 2025 and a loss of Ch$419,352 million in the nine months ended September 30, 2024. The lower losses in 2025 was mainly due to lower short-term interest rates and inflation in 2025 compared to 2024. The average gap between our interest earnings assets and total liabilities linked to the inflation, including hedging, was Ch$7,680,774 million in the nine months ended September 30, 2025 and Ch$7,641,618 million in the nine months ended September 30, 2024. Therefore, our sensitivity to a 100-basis point shift in UF inflation considering our average gap in 2025-to-date would be approximately Ch$77 billion.

The financial impact of the gap between our interest earning assets and liabilities denominated in UFs including hedges was as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **As of September 30,** | **As of September 30,** | **% Change** |
| | **2025** | **2024** | **2025/2024** |
| | **(in millions of Ch$)** | **(in millions of Ch$)** | |
| **Impact of inflation on net interest income** |  |  |  |
| Results from UF GAP(1) | (512486) | (513932) | (0.3)% |
| Annual UF inflation | 2.8% | 3.0% |  |

---

(1)UF GAP is net interest income from asset and liabilities denominated in UFs and includes the results from hedging the size of this gap via interest rate swaps.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The similar result in the nine months ended September 30, 2025 compared to the same period in 2024 was mainly due to similar inflation levels in both years.

***Interest Rates***

Interest rates earned and paid on our assets and liabilities reflect, to a certain degree, inflation, expectations regarding inflation, changes in short term interest rates set by the Central Bank and movements in long term real rates. The Central Bank manages short term interest rates based on its objectives of balancing low inflation and economic growth. Because our liabilities are generally re-priced sooner than our assets, changes in the rate of inflation or short-term rates in the economy are reflected in the rates of interest paid by us on our liabilities before such changes are reflected in the rates of interest earned by us on our assets. Our Financial Management Division usually seeks to maintain liabilities with an average duration that is shorter than that of our assets, including through the use of derivatives, in order to hedge against

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

sudden or rapid falls in the inflation rate, which in general triggers a reduction in short-term rates. Therefore, when short term interest rates fall, our net interest margin is positively impacted, but when short term rates increase, our interest margin is negatively affected. At the same time, our net interest margin tends to be adversely affected in the short term by a decrease in inflation rates since generally our UF-denominated assets exceed our UF-denominated liabilities. See "Item 2. Operating and Financial Review and Prospects—C. Operating Results—Impact of Inflation." An increase in long term rates has a positive effect on our net interest margin, because our interest earning assets generally have longer terms than our interest-bearing liabilities. A flattening of the yield curve, i.e. long-term rates falling quicker than short-term rates, negatively affects our margins by lowering loan yields at a greater pace than deposits costs. In addition, because our peso-denominated liabilities have relatively short re-pricing periods, they are generally more responsive to changes in inflation or short-term rates than our UF-denominated liabilities. As a result, during periods when or expected inflation exceeds the previous period's inflation, customers often switch funds from UF-denominated deposits to peso-denominated deposits, which generally bear higher interest rates, thereby adversely affecting our net interest margin.

We also maintain a substantial amount of non-interest-bearing peso-denominated demand deposits. Because such deposits are non-interest bearing and are not indexed to inflation the higher percentage of our funding that comes from this source positively impacts our net interest margin as interest rates or inflation rises and vice-versa. The ratio of the average of such demand deposits and average shareholder's equity to average interest-earning assets was 33.6% and 32.5% for the nine months ended September 30, 2025 and 2024, respectively.

***Foreign exchange fluctuations***

The Chilean government's economic policies and any future changes in the value of the Chilean peso against the U.S. dollar could adversely affect our financial condition and results of operations. The Chilean peso has been subject to significant devaluation in the past and may be subject to significant fluctuations in the future. The exchange rate appreciated 3.3% in the nine months ended September 30, 2025 and depreciated 4.3% in the same period 2024.

A significant portion of our assets and liabilities are denominated in foreign currencies, principally the U.S. dollar, and we historically have maintained, and may continue to maintain, material gaps between the balances of such assets and liabilities. Because such assets and liabilities, as well as interest earned or paid on such assets and liabilities, and gains and losses realized upon the sale of such assets, are translated to Chilean pesos in preparing our financial statements, our reported income is affected by changes in the value of the Chilean peso relative to foreign currencies (principally the U.S. dollar).

In general, the Bank is not permitted, due to guidelines set by the ALCO and the Market Committee, to open a meaningful gap in foreign currency. Any significant difference between the spot asset position and the spot liability position in foreign currency is usually hedged using forwards and cross-currency swaps. Any remaining foreign currency risk is included as part of the trading portfolio We set an absolute limit on the size of Santander-Chile's consolidated net foreign currency trading position, which is equivalent to the maximum differential allowed between assets and liabilities in foreign currencies, including hedging of this gap. The limit on the size of the net foreign currency position is determined by the Market Committee and is calculated and monitored by the Market Risk Department.

Foreign currency risk included in the trading portfolio is also measured and controlled using VaR. The average VAR of our foreign currency position was U.S.$1.53 million in the nine months ended September 30, 2025. The translation gains or loss over assets and liabilities (excluding derivatives held for trading) is included as foreign exchange transactions in the income statement. The translation and mark-to-market of foreign currency derivatives held for trading is recognized as a gain or loss in the net results from mark-to-market and trading.

***Liquidity risk management***

The Financial Management Division receives information from all the business units on the liquidity profile of their financial assets and liabilities, as well as breakdowns of other projected cash flows stemming from future businesses. On the basis of that information, the Financial Management Division maintains a portfolio of liquid short–term assets, comprised mainly of liquid investments, loans and advances to other banks, to make sure the Bank has sufficient liquidity. The business units' liquidity needs are met through short–term transfers from the Financial Management Division to cover any short–term fluctuations and long–term financing to address all the structural liquidity requirements.

The Bank monitors its liquidity position every day, determining the future flows of its outlays and revenues. In addition, stress tests are performed at the close of each month, for which a variety of scenarios encompassing both normal market conditions and conditions of market fluctuation are used. The liquidity policy and procedures are subject to review and approval by the Bank's Board. Periodic reports are generated by the Market Risk Department, providing a breakdown of the liquidity position of the Bank and its subsidiaries, including any exceptions and the corrective measures adopted, which are regularly submitted to the ALCO for review.

The Bank relies on demand deposits from Retail, Middle-Market and Corporate clients, obligations to banks, debt instruments, and time deposits as its main sources of funding. Our most important source of funding is our deposits. Average time deposits plus non-interest bearing demand deposits represented 44.0% of our average total liabilities and shareholders' equity as of September 30, 2025. As of September 30, 2025, the Bank's top 20 time deposits represented 26.2% of total time deposits, or 6.2% of total liabilities and equity. Our current funding strategy is to continue to utilize all sources of funding in accordance with their costs, their availability and our general asset and liability management strategy. Special emphasis is being placed on lengthening the maturities of funding with institutional clients, diversifying our bond holder base and broadening our core deposit funding. We believe that broadening our deposit base by increasing the number of account holders has created a more stable funding source.

Although most obligations to banks, debt instruments and time deposits mature in over a year, customer (retail) and institutional deposits tend to have shorter maturities and a large proportion of them are payable within 90 days. The short–term nature of these deposits increases the Bank's liquidity risk, and hence, the Bank actively manages this risk by continual supervision of the market trends and price management. 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 higher 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.

*Liquidity Measures Implemented by the Central Bank of Chile as a Result of the COVID-19 Pandemic*

In response to the COVID-19 pandemic, the Central Bank made available two lines of credit to banks to reinforce their liquidity. Pursuant to these lines of credit, a bank may borrow up to 3% of the aggregate amount of its consumer and commercial loan portfolios as of February 29, 2020 and may borrow up to an additional 12% if it uses the funds to provide loans to companies and individuals. The first line of credit is a facility available conditionally on loan growth (the "FCIC") to ensure that banks continue to finance households and businesses in Chile. Loans provided by this line of credit may have maturities of up to four years and must be secured by government bonds, corporate bonds or highly rated large commercial loans as collateral. In stages 1 and 2, the Board of the Central Bank had allocated a total of U.S.$40 billion to this facility, of which approximately U.S.$30 billion was disbursed. The Central Bank in its Monetary Policy Meeting held on January 27, 2021 announced the beginning of a third stage of this instrument (FCIC3) commencing on March 1, 2021 for approximately U.S.$10 billion. The FCIC instruments bore an interest rate of 0.5% (the lowest Central Bank MPR) for the duration of the program. Loans provided under the second line of credit, the LCL, are unsecured and may have maturities of up to 2 years, bearing interest in accordance with the current Central Bank MPR.

Our obligation to the Central Bank under the FCIC program came due in 2024. With the purpose of managing an orderly process of the expiration of the FCIC, in November 2022 the Central Bank established a collateral replacement program with the goal of reducing the pledged credit portfolio by replacing it with eligible Central Bank instruments at a rate of 1/18 per month. Additionally, with the same objective, the Central Bank agreed to implement a program for issuing

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

Liquidity Deposits (LD) aimed exclusively at guaranteeing and providing operational support for the payment of the FCIC. These instruments were issued at floating MPR with the same payment dates of the various FCIC facilities. On April 1 and July 1, 2024, we made payments of Ch$3.3 trillion and Ch$2.8 trillion, respectively of the FCIC using the Central Bank's liquidity deposit program.

Liquidity risk management seeks to ensure that, even under adverse conditions, we have access to the funds necessary to cover client needs, maturing liabilities and capital requirements. Liquidity risk arises in the general funding for our financing, trading and investment activities. It includes the risk of unexpected increases in the cost of funding the portfolio of assets at appropriate maturities and rates, the risk of being unable to liquidate a position in a timely manner at a reasonable price and the risk that we will be required to repay liabilities earlier than anticipated. The ALCO now uses as its liquidity portfolio those defined by the FMC and the Central Bank, which are in line with those established in BIS III. As of September 30, 2025, and December 31, 2024, the breakdown of the Bank's liquid assets by levels was the following:

---

Collateral under the FCIC funding program with the Central Bank of Chile and technical reserves in the Central Bank are not included.

(2)Includes instruments issued by governments, central banks and development banks of foreign countries with a risk rating of A- to AA+ and mortgage bonds issued by Chilean banks that are acceptable at the Central Bank's repo window.

(2)Includes instruments issued by governments, central banks and development banks of foreign countries with a risk rating of A- to AA+ in accordance with international rating agencies and mortgage bonds issued by Chilean banks that are acceptable at the Central Bank's repo window.

The Central Bank and our ALCO also requires us to comply with the following liquidity limits:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity coverage ratio (LCR), which measures the percentage of Liquid Assets over Net Cash Outflows. As of April 2019, Chilean banks began reporting their local LCR figures with a minimum level of 60% in 2020, 80% in 2021 and 100% in 2022. As of September 30, 2025, this indicator for Banco Santander-Chile was 164.7%.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net Stable Funding Ratio (NSFR) which measures a bank's stable funding sources over required stable needs. Beginning in 2022, Chilean banks must have a minimum NSFR ratio of 60% with a gradual phase-in which will reach 100% by 2026. As of September 30, 2025, this indicator for Banco Santander-Chile was 111.0% in compliance with the local regulatory limit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The sum of the liabilities in foreign currency with a maturity of less than 30 days may not exceed the sum of the assets in foreign currency with a maturity of less than 30 days by more than an amount greater than our capital. At September 30, 2025 the liabilities with a maturity of less than 30 days in foreign currency were greater than our assets in foreign currency with a maturity of less than 30 days at a level equivalent to 26% of our capital, thus resulting in our compliance.

***Market risk management***

The Bank's internal management of market risk is based chiefly on the procedures and standards of Santander Spain, which are in turn based on analysis of management in three principal components:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• trading portfolio;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• local financial management portfolio; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• foreign financial management portfolio.

The trading portfolio is comprised chiefly of investments valued at fair market value and free of any restriction on their immediate sale, which are often bought and sold by the Bank with the intention of selling them in the short term to benefit from short–term price fluctuations. The trading portfolio also includes the Bank's exposure to foreign currency. The financial management portfolios include all the financial investments not considered to be part of trading portfolio.

*Market risk – management of trading portfolio*

The Bank applies VaR methodologies to measure the market risk of its trading portfolio. The Bank has a consolidated commercial position comprised of fixed–income investments and foreign currency trading. This portfolio is comprised mostly of Central Bank of Chile bonds, mortgage bonds, locally issued, low–risk corporate bonds and foreign currencies, mainly U.S. dollars. At the end of each year, the trading portfolio included no stock portfolio investments.

For the Bank, the VaR estimate is made under the historical simulation methodology, which consists of observing the behavior of the profits and losses that would have occurred in the current portfolio if the market conditions for a given historical period had been in force, in order to infer the maximum loss on the basis of that information, with a given degree of confidence. The methodology has the advantage of precisely reflecting the historical distribution of the market variables and not requiring any assumptions regarding the distribution of specific probabilities. All the VaR measures are intended to determine the distribution function for a change in the value of a given portfolio, and once that distribution is known, to calculate the percentile related to the necessary degree of confidence, which will be equal to the value at risk by virtue of those parameters. As calculated by the Bank, the VaR is an estimate of the maximum expected loss of market value for a given portfolio over a 1–day horizon, with a 99.00% confidence level. It is the maximum 1–day loss that the Bank could expect to experience in a given portfolio, with a 99.00% confidence level. In other words, it is the loss that the Bank would expect to experience only 1.0% of the time. The VaR provides a single estimate of market risk which is not comparable from one market risk to another. Returns are calculated through the use of a 2–year time window or at least 520 data points obtained since the last reference date for calculation of the VaR going backward in time.

We do not calculate three separate VaRs. We calculate a single VaR for the entire trading portfolio, which in addition is segregated by risk type. The VaR software performs a historical simulation and calculates a Profit and Loss Statement (P&L) for 520 data points (days) for each risk factor (fixed income, foreign currency and variable income.) The P&L of each risk factor is added and a consolidated VaR is calculated with 520 points or days of data. At the same time a VaR is calculated for each risk factor based on the individual P&L calculated for each individual risk factor. Furthermore, a weighted VaR is calculated in the manner described above, but which gives a greater weighting to the 30 most recent data points. The larger of the two VaRs is the one that is reported. In 2024, 2023, and 2022, we used the same VaR model and there has been no change in methodology or assumptions for subsequent periods.

The Bank uses the VaR estimates to provide a warning when the statistically estimated incurred losses in its trading portfolio would exceed prudent levels, and hence, there are certain predetermined limits.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

*Limitations of the VaR model*

When applying a calculation methodology, no assumptions are made regarding the probability distribution of the changes in the risk factors; the historically observed changes are used for the risk factors on which each position in the portfolio will be valued.

It is necessary to define a valuation function fj(xi) for each instrument j, preferably the same one used to calculate the market value and income of the daily position. This valuation function will be applied in each scenario to generate simulated prices for all the instruments in each scenario.

In addition, the VaR methodology is subject to the following limitations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in market rates and prices may not be independent and identically distributed random variables, and may not have a normal distribution; in particular, the assumption of normal distribution may underestimate the probability of extreme market movements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The historical data used by the Bank may not provide the best estimate of the joint distribution of changes in the risk factors in the future, and any modification of the data may be inadequate; In particular, the use of historical data may fail to capture the risk of potential extreme and adverse market fluctuations, regardless of the time period used;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A 1–day time horizon may not fully capture the market risk positions which cannot be liquidated or covered in a single day; it would not be possible to liquidate or cover all the positions in a single day;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The VaR is calculated at the close of business, but trading positions may change substantially in the course of the trading day;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The use of a 99% degree of confidence does not take account of, or make any statement about, the losses that could occur outside of that degree of confidence; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A model such as the VaR does not capture all the complex effects of the risk factors over the value of the positions or portfolios, and accordingly, it could underestimate potential losses.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

We perform back-testing daily and generally find that trading losses exceed our VaR estimate approximately one out of every 100 trading days. At the same time, we set a limit to the maximum VaR that we are willing to accept over our trading portfolio. Also, a maximum VaR limit was established that can be applied over the trading portfolio.

The average VaR as of September 30, 2025 was U.S.$2.02 million, which is below the total limit.

The high, low, and average levels for each component and each period below were as follows:

*Market risk – local and foreign financial management*

The Bank's financial management portfolio includes most of the Bank's non-trading assets and liabilities, including the credit/loan portfolio. For these portfolios, investment and financing decisions are strongly influenced by the Bank's commercial strategies.

The Bank uses a sensitivity analysis to measure the market risk of local and foreign currencies (not included in the trading portfolio). The Bank performs a simulation of scenarios, which will be calculated as the difference between the present value of the flows in the chosen scenario and their value in the base scenario. All the positions in local currency, including the one indexed to inflation (UF), and also the positions in foreign currency are added together based on a historical correlation model existing between the currencies. The Bank has also established limits regarding the maximum loss that these types of movements in interest rates may have on capital and net financial income budgeted for the year.

*Limitations of the sensitivity models*

The most important assumption is using a parallel shift of the yield curve of 100bp in 2025 and 2024. Santander Spain Global Risk Department has also established comparable limits by country, to be able to compare, monitor and consolidate market risk by country in a realistic and orderly way.

------

<u>[Table of contents](#i968d7ef8279e4569bd2dc01d0fb62352_7)</u>

In addition, the sensitivity simulation methodology should be interpreted taking into consideration the following limitations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The simulation of scenarios assumes that the volumes remain consistent in the Bank's Consolidated Statements of Financial Position and are always renewed at maturity, also including certain credit risk and prepayment considerations that may affect the maturity of certain positions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This model assumes an identical change along the entire length of the yield curve and does not take into account the different movements for different maturities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The model does not take into account the sensitivity of volumes which results from interest rate changes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The limits to losses of budgeted financial income are calculated based on the financial income foreseen for the year, which may not be actually earned, meaning that the real percentage of financial income at risk may be higher than the expected one.

*Market risk –Regulatory method*

The following table illustrates our market risk exposure according to the Chilean regulatory method, as of September 30, 2025. According to local regulation, the short-term exposure to interest rate risk and inflation risk as a percentage of net interest and inflation income and net fee income sensitive to interest rates, accumulated in the last 12 months, should not exceed a limit established by the Bank's Board. The Board set a limit equal to 55% of net income from interest and inflation and net income from fees sensitive to interest rates. Furthermore, long-term exposure to interest rates for the banking book as a percentage of regulatory capital should not exceed a limit established by the Bank's Board. The

------

***Derivative activities***

At September 30, 2025 and 2024, derivatives are valued at market price on the balance sheet and the net unrealized gain (loss) on derivatives is classified as a separate line item on the income statement. Notional amounts are not recorded on the balance sheet. Banks must mark-to-market derivatives. A derivative financial instrument held for trading purposes must be marked to market and the unrealized gain or loss recognized in the income statement. The FMC recognizes three kinds of hedge accounting: (i) cash flow hedges, (ii) fair value hedges and (iii) hedging of foreign investments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• When a cash flow hedge exists, the fair value movements on the part of the hedging instrument that is effective are recognized in equity. Any ineffective portion of the fair value movement on the hedging instrument is recognized in the income statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• When a fair value hedge exists, the fair value movements on the hedging instrument and the corresponding fair value movements on the hedged item are recognized in the income statement. Hedged items in the balance sheet are presented at their market value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• When a hedge of foreign investment exposure exists (*i.e.* investment in a foreign branch), the fair value movements on the part of the hedging instrument that is effective are recognized in equity. Any ineffective portion of the fair value movement on the hedging instrument is recognized in the income statement.

In order to reduce the credit risk in its derivative contracts, the Bank has entered into Credit Support Annex (CSA) agreements with the majority of its counterparties, which include obligations to post daily cash collateral. The majority of the agreements include an obligation to post collateral with a threshold amount of zero. In the table below we identify those

We also use derivatives to hedge our exposure to foreign exchange, interest rate and inflation risks. The Bank uses derivatives, mainly Ch$/UF swaps, in order to cover its exposure to inflation due to a higher amount of assets linked to inflation as compared to liabilities. Such derivatives are accounted for as cash flow hedges. Our Financial Management Division usually seeks to maintain liabilities with an average duration that is shorter than that of our assets, including through the use of derivatives, in order to hedge against sudden or rapid falls in the inflation rate, which in general triggers a reduction in short-term rates. To maintain this position, the Bank enters into interest rate swaps that are accounted for as fair value hedges.

As of September 30, 2025 and December 31, 2024 the Bank holds the following portfolio of derivative instruments for hedging purposes:

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**1. Preparation basis**

These Interim Consolidated Financial Statements have been prepared following the Compendium of Accounting Standards for Banks (CASB), in its version applicable as of January 2022, as well as the instructions issued by the FMC. The FMC, under Law No 21,000, provides in numeral 6 of article 5 that the Financial Market Commission may set the rules for the preparation and presentation of the annual reports, balance sheets, statements of financial position and other financial statements of the supervised entities and determines the principles according to which companies must keep their accounts. Regarding all matters that are not covered by this regulation, if they do not conflict with its instructions, then they must adhere to generally accepted accounting criteria corresponding to the technical standards issued by the Chilean Association of Accountants AG, which coincide with the International Financial Reporting Standards (IFRS) agreed by the International Accounting Standards Board (IASB). In case of discrepancies between the accounting principles and the accounting criteria issued by the FMC in its Compendium of Accounting Standards for Banks and instructions, the latter shall prevail.

The Bank uses certain currency terms and conventions for these Interim Consolidated Financial Statements. Thus, 'USD' stands for 'US dollar', 'EUR' stands for 'euro', 'CNY' stands for 'Chinese yuan', 'JPY' stands for 'Japanese yen', 'CHF' stands for 'Swiss franc', 'AUD' stands for 'Australian dollar' and 'UF' stands for 'Unidad de Fomento de Chile'.

The notes in the Interim Consolidated Financial Statements contain information in addition to that presented in the Interim Consolidated Statements of Financial Position, Interim Consolidated Statements of Income, Interim Consolidated Statements of Other Comprehensive Income,Interim Consolidated Statement of Change in Equity and Interim Consolidated Statement of Cash Flows. They provide narrative descriptions or disaggregation of such states in a clear, relevant, reliable and comparable manner.

**2. Preparation of the Interim Consolidated Financial Statements**

The Interim Consolidated Financial Statements as of September 30, 2025, and December 31, 2024 incorporate the individual financial statements of the Bank and its controlled entities (affiliates) and include the adjustments, reclassifying and eliminations necessary to comply with the accounting and measurement criteria established by IFRS 10 'Consolidated Financial Statements'. Control is achieved when the Bank:

i.Has power over the investee (that is, it has rights that grant it the present capacity to manage the relevant activities of the investee);

ii.Has exposure or rights to variable returns from its involvement with the investee; and

iii.Has the ability to use its power over the investee to influence the amount of the investor's returns.

The Bank reassesses whether it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. For example, when the Bank has less than most of the voting rights in an investee, but those voting rights are sufficient to have the ability to direct the relevant activities, then it is concluded that the Bank has control. The Bank considers all relevant facts and circumstances in assessing whether the Bank's voting rights in an investee are sufficient to give it power. These include:

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

• The size of the Bank's holding of voting rights relative to the size and dispersion of holdings of the other vote holders.

• The potential voting rights held by the Bank, other vote holders or other parties.

• The rights arising from other contractual agreements.

• Any additional facts and circumstances that indicate that the Bank has or does not have the current ability to direct the relevant activities when decisions need to be made, including voting patterns at previous shareholders' meetings.

Consolidation of a subsidiary begins when the Bank obtains control of the subsidiary and ceases when the Bank cedes control. Specifically, the income and expenses of a subsidiary acquired or disposed of during the period are included in the Interim Consolidated Statements of Income and Interim Consolidated Statements of Other Comprehensive Income from the date the Bank gains control until the date the Bank ceases to control the subsidiary.

Profit or loss alongside each component of the Interim Consolidated Statements of Other Comprehensive Income is attributed to the Bank's holders and non-controlling interest. The total comprehensive income of subsidiaries is attributed to the owners of the Bank and the non-controlling interests, even if this results in the non-controlling interests having a deficit in certain circumstances. When necessary, adjustments are made to the financial statements of the subsidiaries to ensure their accounting standards are consistent with the Bank's accounting standards. All balances and transactions between consolidated entities are eliminated.

Changes in the consolidated entities' participation that do not result in the loss of control are accounted for as equity transactions. Accordingly, the book value of the Bank's equity holders and the non-controlling interests are adjusted to reflect the changes in participation over subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration being paid or received is recognized directly in equity and attributed to the equity owners of the Bank.

The non-controlling interest represents the participation of third parties in the Bank's consolidated equity, which is presented in the Interim Consolidated Statement of Change in Equity. Their share of the result for the year is shown as 'Profit attributable to non-controlling interest' in the Interim Consolidated Statements of Income.

The following table shows the composition of the entities over which the Bank can exercise control and, therefore, form part of the consolidation perimeter:

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

The Bank was authorized by the FMC to carry out the sale of its stake in the subsidiary Klare Corredora de Seguros S.A., which was finalized at the close of fiscal year 2024, and therefore is no longer part of the Bank's consolidation perimeter.

**ii.Entities controlled by the Bank through other considerations and Associates**

The following companies have been consolidated based on the fact that the Bank determines their relevant activities (these are companies complementary to the banking sector) and, therefore, over which the Bank exercises control:

• Santander Gestión de Recaudación y Cobranza Limitada: its exclusive activity is administering and collecting loans.

• Multiplica SpA: its primary purpose is the development of incentive programs that encourage the use of payment cards.

The company Bansa Santander S.A. was included in the consolidation perimeter until May 2024. The company Pagonxt Payments Chile SpA was included in the consolidation perimeter until December 2024. See Note 05 – Significant Events.

An associate is an entity over which the Bank can exercise significant influence but not control or joint control. This capacity is usually manifested in a 20% or more interest in the entity's voting rights and is accounted for using the equity method in accordance with IAS 28 'Investments in Associates and Joint Ventures'.

The following entities in which the Bank has an interest and are recognized using the equity method are considered 'associates':

---

| Servicios de Infraestructura de Mercado OTC S.A. | Administration of the infrastructure for the financial market of derivative instruments | Santiago, Chile | 12.48 | 12.48 | 12.48 |

---

In the case of Cámara Compensación de Alto Valor S.A. and Servicios de Infraestructura de Mercado OTC S.A., Banco Santander-Chile has a representative on the Board of Directors, which is why the Administration has concluded that it exercises significant influence.

**iii.Share or rights in other companies**

Entities over which the Bank has no control or significant influence are presented in this category. These equity instruments must be measured at fair value in compliance with IFRS 9 'Financial Instruments'. Nevertheless, the Bank may consider the cost an appropriate fair value estimate in concrete circumstances. This may be the case if the most recently available information is insufficient to measure the fair value or if a wide range of possible fair value measurements and the cost involved represents the best estimate of fair value within that range.

In another regard, the Bank may make an irrevocable decision to present subsequent changes to the fair value in other comprehensive income during its initial recognition. Subsequent changes in this valuation shall be recognized in 'Accumulated other comprehensive income - Items that will not be reclassified to profit or loss'. Dividends received from these investments are recorded in the Interim Consolidated Statements of Income under 'Result from investments in companies'. These instruments are not subject to the IFRS 9 'Financial Instruments' impairment model.

**3. Non-controlling interest**

Non-controlling interest represents the portion of net income and net assets the Bank does not own, either directly or indirectly. It is presented separately in the Interim Consolidated Statements of Income and separately from the equity in the Interim Consolidated Statements of Financial Position .

In the case of entities controlled by the Bank through other considerations, profit and equity are presented fully as a non-controlling interest. This is because the Bank controls them, but has no ownership expressed as a percentage.

**4. Reporting segments**

The Bank's operating segments are those units whose operating results are reviewed regularly by the highest level of management regarding decision-making. Accordingly, two or more operating segments can be added into one only when the aggregation is consistent with the basic principle under the IFRS 8 'Operating Segments' and if the segments have similar economic characteristics and are alike in each one of the following aspects:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.The nature of the products and services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.The nature of production processes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.The type of customer category for which its products and services are intended.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv.The methods used to distribute their products or provide services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v.If applicable, the nature of the regulatory framework, e.g., banking, insurance, utilities.

The Bank reports separately for each operating segment that meets any of the following quantitative thresholds:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Its reported revenues from ordinary activities, including both sales to external clients and inter-segment sales or transactions, equal or exceed 10% of the combined revenues from all operating segments' ordinary internal and external activities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.The amount of its reported results is, in absolute terms, equal to or greater than 10% of the greater of (i) the combined profit reported by all operating segments that have not reported a loss; and (ii) the combined loss reported by all operating segments that have reported a loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.Its assets equal or exceed 10% of the combined assets of all operating segments.

Operating segments that do not meet any of the quantitative thresholds may be considered reportable segments. The information must be disclosed separately if management believes it would be helpful to Interim Consolidated Financial Statements users.

Information regarding other business activities that do not correspond to reportable segments is combined and disclosed within the Corporate Activities category 'other'.

Concerning the above, the Bank's segments were obtained under the consideration that an operating segment is a component of an entity that:

&nbsp;&nbsp;&nbsp;&nbsp;i.Engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses from transactions with other elements of the same entity).

&nbsp;&nbsp;&nbsp;&nbsp;ii.Whose operating results are regularly reviewed by the entity's chief executive officer, who makes decisions about resources allocated to the segment and assesses its performance.

&nbsp;&nbsp;&nbsp;&nbsp;iii.For which discrete financial information is available.

**5. Functional and presentation currency**

The Bank, in according to IAS 21 'The Effects of Changes in Foreign Exchange Rates', has defined the Chilean Peso as its functional and presentation currency, as this is the currency of the primary economic environment in which the Bank operates, as well as the currency that influences the cost and revenue structure. Therefore, all balances and transactions denominated in currencies other than the Chilean Peso are considered 'foreign currency'.

**6. Transaction in foreign currencies**

The Bank conducts transactions in amounts denominated in foreign currencies, mainly US dollars. The assets and liabilities denominated in foreign currencies held by the Bank and its affiliates are translated into Chilean Pesos at the market exchange rate corresponding to the end of the reported month (spot rate), which amounts to $961.65 per US$1 for September 2025 and $912.36 for September 2024 ($994.10 per US$1 for December 2024). For all other currencies, an external pricing provider is used.

The net foreign exchange gain and loss includes recognizing the effects of exchange rate changes on assets and liabilities denominated in foreign currencies and the profit and loss on foreign exchange spot and forward transactions undertaken by the Bank.

**7. Cash and cash equivalents**

The indirect method is used to prepare the Interim Consolidated Statement of Cash Flows, starting with the Bank's consolidated pre-tax income, and then incorporating non-cash transactions, cash-flow-related income, and expense of activities classified as investments or financing.

The following items are taken into consideration in the preparation of the Interim Consolidated Statement of Cash Flows:

i.Cash flows: inflows and outflows of cash and cash equivalents, defined as balances in items such as deposits with the Central Bank of Chile, deposits in domestic banks and deposits abroad.

ii.Operating activities: these are the normal activities carried out by banks alongside other activities that cannot be classified as investments or financing.

iii.Investing activities: these correspond to the acquisition, sale or disposal by other means of long-term assets and other investments not included in cash and cash equivalents.

iv.Financing activities: those that result in changes to the size and composition of equity and liabilities that are not part of operating or investing activities.

**8. Definitions, classification and measurement of financial assets/liabilities**

**i.Definitions**

A 'financial instrument' is any contract that gives rise to a financial asset in an entity and a financial liability or equity instrument in another entity.

A 'financial asset' is any asset that is: (a) cash; (b) an equity instrument of another entity; (c) a contractual right to receive cash or another financial asset from another entity or to exchange financial assets or financial liabilities with another entity under conditions that are potentially favorable to the entity; or (d) a contract that will or may be settled using the entity's own equity instruments.

A 'financial liability' is any liability that is: (a) a contractual obligation to deliver cash or another financial asset to another entity or to exchange financial assets or financial liabilities with another entity under conditions that are potentially unfavorable to the entity; or (b) a contract that will or may be settled using the entity's equity instruments.

An 'equity instrument' is any contract that evidences a residual interest in the assets of the issuing entity after deducting all of its liabilities.

A 'financial derivative' is a financial instrument whose value fluctuates in response to changes concerning an observed market variable (such as an interest rate, a foreign exchange rate, a financial instrument's price, or a market index, including credit ratings), whose initial investment is minimal compared with other financial instruments with a similar response to changes in market factors, and which is generally settled at a future date.

'Fair value' is the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants at the measurement date.

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

**ii.Initial recognition**

The Bank shall recognize a financial asset or financial liability only when it becomes part of the contractual terms of the instrument (rights and obligations).

A conventional purchase or sale of financial assets shall be recognized using the accounting contract date or settlement date.

**iii.Classification of financial assets/liabilities**

***Classification of financial assets***

Financial assets shall be classified into measurement categories based on the entity's business models for managing the financial assets and the contractual cash flow characteristics of said assets.

The business model refers to how the Bank manages its financial assets to generate cash flows. In other words, the entity's business model determines whether the cash flows will come by obtaining contractual cash flows, selling financial assets, or both.

Assessing the contractual flow characteristics (SPPI test) requires determining whether the asset's contractual flows are solely payments of principal on specified dates and interest on the principal outstanding amounts in the currency in which the financial asset is denominated. The principal is the fair value of the financial asset at initial recognition. Nevertheless, the principal amount may change over the life of the financial asset (if there are principal repayments). Interest is the compensation received for the time value of money and the credit risk related to the principal amount owed over a specified period, alongside other risks and administrative costs, and a profit margin.

For the assessment, the Bank conducts a test evaluating whether the contractual flows meet the criteria for a core lending arrangement. The Bank uses its professional assessment and considers relevant factors such as currency, interest rate (fixed or variable) and the period it sets.

The assessment of business models is not an instrument-by-instrument ranking approach but at a higher level of aggregation and considers all relevant evidence: model performance, risks affecting performance, and how managers are rewarded, among others.

According to the above, the objectives of the business models are:

• To hold assets to collect cash flows – through management that produces cash flows by collecting contractual payments throughout the instrument's life. Models with this goal allow for sales if they are infrequent (even if significant in value) or insignificant in value both individually and in aggregate (even if frequent), and even more so if they result from a substantial increment in risk or the risk management of credit concentration.

• To maintain financial assets for collection and sale. Per this objective, the entity's key management personnel have decided that the supply of contractual cash flows and the sale of financial assets are essential to achieve the business model's goal. Therefore, there is a higher frequency and value of sales for this purpose.

• Other models - financial assets are measured at fair value through profit or loss if they are not held within a business model whose objective is to hold the assets to collect contractual cash flows or if their objective is achieved by obtaining contractual cash flows and selling financial assets. Assets are managed on a sales basis, and decisions are made on a fair value basis.

In accordance with the above, the Bank will classify its financial assets based on whether they are subsequently measured at amortized cost, at fair value through other comprehensive income, or at fair value through profit or loss.

Additionally, an irrevocable election may be made at the time of initial recognition of investments in equity instruments to present subsequent changes in fair value in other comprehensive income.

***Classification of financial liabilities***

An entity shall classify all financial liabilities as subsequently measured at amortized cost, except for derivative liabilities measured at fair value through profit or loss.

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

***Reclassifications***

Reclassifying financial assets only occurs only when the business model for managing financial assets has changed. These changes are determined by top management due to external or internal changes. Financial liabilities are not reclassified.

**iv.Measurement of financial assets/liabilities**

***Initial measurement***

Financial assets and liabilities are initially measured at fair value (transaction price), plus or minus transaction costs in the case of a financial asset or financial liability that is not carried at fair value through profit or loss.

***Subsequent measurement of financial assets***

A financial asset shall subsequently be measured according to the following:

(i)Amortized cost

A financial asset is measured at amortized cost if the financial asset is held within a business model whose objective is to hold financial assets to earn cash flows, and the contractual terms of the financial asset give rise, at specified dates, to cash flows that are solely payments of principal and interest on the outstanding principal amount.

Interest income shall be calculated using the effective interest method. This method applies to financial assets and liabilities measured at amortized cost (interest income and interest expense). The effective interest rate is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial asset or financial liability to the gross carrying amount of the financial asset or the amortized cost of a financial liability.

(ii)Fair value through other comprehensive income

A financial asset is measured at fair value through other comprehensive income if the financial asset is held within a business model in which the objective are to obtain the contractual cash flows, to sell financial assets, and if the contractual terms of the financial asset give rise, at specified dates, to receive cash flows that are solely payments of principal and interest on the outstanding principal amount.

(iii)Fair value through profit or loss

A financial asset is measured at fair value through profit or loss unless measured at amortized cost or fair value through other comprehensive income.

(iv)Irrevocable election to measure at fair value with changes in other comprehensive income.

Upon the initial recognition of Investments in equity instruments, a determination may be held to present subsequent changes in fair value in other comprehensive income that would otherwise be measured at fair value through profit or loss when not held for trading, except for dividend income, which is recognized in profit or loss for the period. Gains or losses arising from the de-recognition of these equity instruments are not transferred to profit or loss.

***Subsequent measurement of financial liabilities***

Financial liabilities are subsequently measured at amortized cost, except for derivatives measured at fair value through profit or loss.

**v.De- recognition of financial assets/liabilities**

A financial asset shall be derecognized when and only when:

(i)The contractual rights to the cash flow from the financial asset expire, or

(ii)The contractual rights to receive the cash flows of a financial asset are transferred, or it retains the contractual rights to receive the cash flows of a financial asset but assumes a contractual obligation to pay them to one or more recipients. In this sense, if the risks and rewards of ownership of the financial asset are substantially transferred, the financial asset is derecognized.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

In the case of unconditional sales, sales under repurchase agreements at fair value at the date of repurchase, sales of financial assets with a purchased call option or a written put option that is deeply out of the money, uses of assets where the transferor does not retain subordinated financing nor grants any credit enhancement to the new owners, and other similar cases, the transferred financial asset is recognized from the Interim Consolidated Statements of Financial Position with simultaneous recognition of any rights or obligations retained or created as a result of the transfer.

In the case of sales of financial assets: (i) under fixed-price repurchase agreements or using the sale price plus interest, (ii) of securities lending agreements in which the borrower must return the same or (iii) similar assets and in other akin cases, the transferred financial asset is not recognized from the Interim Consolidated Statements of Financial Position and continues to be measured using the same criteria as before the transfer.

A financial liability is recognized when and only when it is extinguished – that is, when the obligation specified in the contract is paid for, cancelled or expired. In the case of loans, the FMC requirements for recognition apply. See letter o), VIII.

**vi. Offsetting a financial asset with a financial liability**

A financial asset and a financial liability shall be offset and presented by their net amount in the Interim Consolidated Statements of Financial Position when, and only when, there is now a legally enforceable right to set off the recognized amounts and an intention to settle the net amount or to realize the asset and settle the liability, simultaneously. As of September 30, 2025, and 2024, and December 31, 2024, the Bank has no financial asset/liability that offset.

**9. Financial derivatives and hedge accounting**

Derivatives are classified as either trading instruments or hedging instruments. The Bank uses financial derivatives for the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.To provide such instruments to customers who request them to manage their market and credit risks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.To use them for the risk management of the proprietary position of the Bank's entities and their assets and liabilities ('hedging derivatives').

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.To benefit from changes in the value of these derivatives (trading derivatives).

Trading derivatives are measured at fair value through profit or loss and are presented as assets/liabilities according to their positive or negative fair value. Derivatives that do not qualify as hedging instruments are accounted for as trading instruments.

The Bank has elected to continue to use the IAS 39 guidelines for hedge accounting. For a financial derivative to be considered a hedging derivative, all the following conditions must be met:

1. To cover one of the following three types of risk:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.Changes in the value of assets and liabilities due to fluctuations in, among other things, inflation (UF), interest rates and/or exchange rates to which the position or balance to be hedged is subject ('fair value hedging').

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Changes in estimated cash flows originating from financial assets and liabilities, highly probable commitments and transactions that are expected to be carried out ("cash flow hedge").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.The net investment in a foreign operation ('hedge of a net investment in a foreign operation').

2. To effectively eliminate some risk inherent in the hedged item or position for the entire expected term of the hedge, which entails that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.At the date of arrangement, the hedge is expected, under normal conditions, to be highly effective ('prospective effectiveness').

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.There is sufficient evidence that the hedge was effective during the life of the hedged item or position ('retrospective effectiveness').

3. There must be adequate documentation evidencing the specific designation of the financial derivative to hedge certain balances or transactions and how this effective hedge was expected to be achieved and measured, provided that this is consistent with the Bank's management of its risks.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

The changes in the value of financial instruments qualifying for hedge accounting are recorded as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.For fair value hedges, the gains or losses arising on both hedging instruments and the hedged items (attributable to the type of risk being hedged) are included as 'Net income (expense) from financial operations' in the Interim Consolidated Statements of Income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.For fair value hedges of the interest rate risk of a portfolio of financial instruments ('macro-hedges'), gains or losses arising on measurement of the hedging instruments are recognized directly in the Interim Consolidated Statements of Income under 'Interest and adjustment income'.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.For cash flow hedges, the efficient portion of the change in the value of the hedging instrument is recorded in the Interim Consolidated Statements of Other Comprehensive Income in 'Valuation accounts - cash flow hedges' within equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Differences in the valuation of the hedging instrument corresponding to the inefficient portion of cash flow hedging transactions are recognized directly in the Interim Consolidated Statements of Income in 'Net income from financial operations'.

If a derivative designated as a hedge, whether due to termination, ineffectiveness, or any other cause, does not meet the above requirements, hedge accounting is discontinued. When 'fair value hedging' is discontinued, the fair value adjustments to the carrying amount of the hedged item arising from the hedged risk are amortized to gain or loss from that date, when applicable.

When cash flow hedges are discontinued, the cumulative gain or loss on the hedging instrument recognized in the Interim Consolidated Statements of Other Comprehensive Income in equity 'Valuation Accounts' (while the hedge was efficient) continues to be recognized in equity until the hedged transaction occurs. At that time, it is recognized in the Interim Consolidated Statements of Income unless the transaction is not expected to occur, in which case it is recognized immediately in the Interim Consolidated Statements of Income.

***Embedded derivatives in hybrid financial instruments***

'Embedded derivatives' is a hybrid contract component that simultaneously includes a host contract that is not a derivative and a financial derivative that is not individually transferable. It has the effect that some of the cash flows of the hybrid contract vary in the same way as the embedded derivative would on a stand-alone basis. As of September 30, 2025, and 2024, and December 31, 2024, Banco Santander-Chile holds embedded derivatives in dual currency contracts in its portfolio.

**10. Fair value of financial assets and liabilities**

No transaction costs are deducted when financial assets and liabilities are measured at fair value. Assets and liabilities subsequently measured at amortized cost are not required to be measured at fair value.

'Fair value' is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction in the principal market at the measurement date under current market conditions (i.e., an exit price) regardless of whether that price is directly observable or estimated using another valuation technique. Fair value measurement is for a specific asset or liability. Therefore, in measuring fair value, the Bank considers the characteristics of the asset or liability in the same way that market participants would consider in pricing the asset or liability at the measurement date. In addition, the fair value measurement assumes that the transaction of selling the asset or transferring the liability takes place either: (a) in the principal market for the asset or liability or (b) in the absence of a principal market, the most advantageous market for the asset or liability.

When there is no market price for a given financial instrument, its fair value is estimated based on the price established in recent transactions involving similar instruments or, in the absence thereof, based on valuation models sufficiently contrasted by the international financial community, considering the specific peculiarities of the instrument to be valued and especially, the different types of risk related to the instrument.

When valuation techniques are used, they maximize the use of the relevant observable input data and minimize that of unobservable input data. For example, when an asset or a liability measured at fair value has a bid price and an asking price, the price within the bid-ask spread that is most representative of fair value in the circumstances shall be used to measure fair value regardless of where the input is categorized within the fair value hierarchy.

Although average prices are allowed as a practical resource to determine the fair value of an asset or a liability, the Bank makes an adjustment (FVA or fair value adjustment) when there is a gap between the purchase and sale price (close-out cost).

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

All derivatives are recorded in the Interim Consolidated Statements of Financial Position at fair value from the trade date. If their fair value is positive, they shall be recorded as an asset; if their fair value is negative, they shall be recorded as a liability. In the absence of evidence to the contrary, the trade date's fair value is deemed the transaction price. Changes in the fair value of derivatives from the trade date are recognized with a balancing entry in the Interim Consolidated Statements of Income under "Profit/(loss) on financial assets/liabilities held for trading at fair value through profit or loss".

Specifically, the fair value of financial derivatives included in the trading books is deemed similar to their daily quoted price. If, for exceptional reasons, the quoted price cannot be determined on a given date, the fair value is calculated using similar methods to those used for over-the-counter (OTC) derivatives. The fair value of OTC derivatives is the sum of the future cash flows stemming from the instrument that have been discounted to the present value at the appraisal date ('present value' or 'theoretical closure') using valuation techniques commonly used by the financial markets: 'net present value' (NPV) and option pricing models, among other methods. Also, within the fair value of derivatives are included the credit risk of the derivative, be it the Bank's own credit risk (Debt Valuation Adjustment or "DVA") or the counterparty's credit risk (Credit Valuation Adjustment or "CVA"). The Counterparty Credit Risk (CVA) is a valuation adjustment to derivatives contracted in non-organized markets because of the exposure to counterparty credit risk.

The CVA is calculated considering the potential exposure to each counterparty in future periods. The Debit Valuation Adjustment (DVA) is a valuation adjustment similar to CVA, but generated by the Bank's credit risk assumed by our counterparties. In the case of derivative instruments contracted with Central Clearing Houses, where the variation margin is contractually defined as a firm and irrevocable payment, this payment is considered part of the derivative's fair value.

For loans and advances covered by fair value hedging transactions, changes in their fair value related to the risk or risks covered in these hedging transactions are recorded.

Equity instruments and contracts related to these instruments must be measured at fair value. Nevertheless, in certain circumstances, the Bank may use cost as an appropriate fair value estimate. This may be necessary, for example, if the recently available information is insufficient to measure the fair value or if a wide range of possible fair value measures exists, and the cost represents the best fair value estimate within that range. Furthermore, the Bank may irrevocably elect to present subsequent changes in the instrument's fair value in other comprehensive income.

As of September 30, 2025, and 2024, and December 31, 2024, no significant investments in listed financial instruments had ceased to be recorded at their quoted market value due to their market being unable to be considered active.

The amounts at which financial assets/liabilities are recorded represent, in all material respects, the Bank's maximum exposure to credit risk at each reporting date. The Bank also has collateral and other credit enhancements to mitigate its exposure to credit risk, consisting mainly of mortgages, cash, equity and personal guarantees, leased and rented assets, assets purchased under repurchase agreements, securities lending and credit derivatives.

***Valuation techniques***

According to IFRS 13 'Fair Value Measurement', a fair value hierarchy is established based on three levels: Level 1, Level 2 and Level 3, in which the highest priority is given to quoted prices (unadjusted) in active markets for identical assets and liabilities and the lowest priority to unobservable inputs.

Financial instruments at fair value and determined by published prices in active markets (Level 1) comprise government bonds, corporate bonds, exchange-traded derivatives, securitized assets, equities, short positions and issued bonds.

In cases where quotations cannot be observed, management best estimates what the market would price using its own internal models. In most cases, these internal models use data based on observable market parameters as significant inputs (level 2) and sometimes use significant unobservable inputs in market data (level 3). Various techniques are used to estimate it, including extrapolating observable market data. The most reliable evidence of the fair value of a financial instrument on initial recognition is the transaction price unless the value of that instrument can be derived from other market transactions by the same or a similar instrument or valued using a valuation technique in which the inputs used include only observable market data, mainly interest rates.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

The main techniques used as of September 30, 2025, and 2024, and December 31, 2024 by the Bank's internal models to determine the fair value of financial instruments are described below:

i.The present value method is used to value financial instruments that allow static hedging (mainly forwards and swaps). Expected future cash flows are discounted using the interest rate curves of the corresponding currencies. As a rule, interest rate curves are data that can be observed on the markets.

ii.In the valuation of financial instruments that require dynamic hedging (mainly structured options and other structured instruments), the "Black-Scholes" model is normally used. Where appropriate, observable market inputs are used to obtain factors such as the diluted bid-offer, exchange rates, volatility, correlation between indices and market liquidity.

iii.In the valuation of certain financial instruments subject to interest rate risk, such as interest rate futures, caps and floors, the present value method (futures) and the "Black-Scholes" model ("plain vanilla" options) are used. The main inputs used in these models are mainly observable market data, including the corresponding interest rate curves, volatilities, correlations and exchange rates.

The fair value of the financial instruments calculated by the aforementioned internal models considers contractual terms and observable market data, including interest rates, credit risk, exchange rates, the quoted market price of shares and market rates of raw materials, volatility, prepayments and liquidity. The Bank's management verifies that the valuation models do not incorporate significant subjectivity. Therefore, if necessary, these methodologies can be adjusted and calibrated through internal calculations of fair value and subsequent comparison with the corresponding actively traded prices.

The Bank has developed a formal process for the systematic valuation and management of financial instruments, implemented in all units included in the scope of consolidation. The governance structure of this process distributes responsibilities between two separate divisions: Treasury (responsible for the development, marketing and daily management of financial products and market data) and Market Risks (responsible for the periodic validation of valuation models and market data, the process of calculating risk metrics, standards for approving new transactions, market risk management and the implementation of valuation adjustment standards).

Approving a new product involves several steps (application, development, validation, integration into corporate systems and quality review) before production. This process ensures the rating systems are properly reviewed and stable before use.

Details of the most significant derivative products and families, together with their respective valuation techniques and inputs, by type of asset, are set out in Note 44 'Fair value of financial assets and liabilities' in these Interim Consolidated Financial Statements.

**11. Fixed assets**

This category includes the buildings, land, furniture, vehicles, computer hardware and other fixed assets owned by the consolidated entities. Assets are classified according to their use as follows:

**a. Fixed assets for own use**

Fixed assets for own use are presented at their acquisition cost, less its corresponding accumulated depreciation and, if applicable, the impairment losses that result from comparing the net value of each item with its corresponding recoverable amount. This includes, among others, the material assets received by the consolidated entities for the liquidation, in whole or in part, of financial assets that represent collection rights against third parties, and which are expected to be continuously used and owned.

Depreciation is calculated using the straight-line method over the acquisition cost of assets minus their residual value, assuming that the land on which buildings and other structures stand has an indefinite life and is not subject to depreciation. The Bank applies the following useful lives for the tangible assets that comprise its assets:

| Land | - |
| Paintings and works of art | - |

| Rights over telephone lines | 64 |
| Air conditioning systems | 84 |
| ATMs and teleconsultations | 120 |
| Other installations | 120 |
| Buildings | 1200 |

---

At each reporting period, the consolidated entities assess whether there is any indicator that the carrying amount of any tangible asset exceeds its recoverable amount. If this is the case, the asset's carrying amount is reduced to its recoverable amount. Future depreciation charges are adjusted under the revised carrying amount and to the new remaining useful life, if an adjustment of the latter is necessary.

Likewise, the estimated useful lives of the items of property, plant and equipment held for own use are reviewed at the end of each reporting period to detect significant changes. If changes are detected, the useful lives of the assets are adjusted by correcting the depreciation charge to be recorded in the Interim Consolidated Statements of Income in future years based on the new useful lives.

Maintenance expenses relating to tangible assets held for own use are recorded as an expense in the period in which they are incurred.

**b. Assets leased out under operating leases**

The criteria used to record the acquisition cost of assets leased out under operating leases, calculate their depreciation and their respective estimated useful lives, and record their impairment loss are the same criteria as those for fixed assets held for own use.

**12. Leases**

At the contract's creation, the Bank assesses whether it contains a lease or not. A contract contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for compensation. To assess whether a contract conveys the right to control the use of an identified asset, the Bank assesses whether:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The contract involves using an identified asset. This may be specified explicitly or implicitly and should be physically identified. The asset is not identified if the supplier has a significant substitution right.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Bank has the right to obtain all the economic benefits from using the asset throughout the contract's duration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Bank has the right to direct the use of the asset – this is the decision-making purpose for which the asset is used.

**i.As a lessee**

The Bank recognizes a right-of-use asset and a lease liability at the starting date of the lease according to the IFRS 16 'Leases'. The Bank's main contracts are for offices and branches which are necessary to undertake its activities.

Interim Consolidated Financial Statements &nbsp;&nbsp;&nbsp;&nbsp;September 2025 / Banco Santander-Chile F-22

Banco Santander-Chile and Affiliates

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

In the beginning, the right-of-use asset is equal to the lease liability. It is calculated as the present value of the lease payments, which are discounted using the Bank's incremental interest rate at the starting date and considering each contract's duration. The average incremental interest rate is 1.69%. Subsequently, the asset is straight-line depreciated according to the contract's duration, and the financial liability is amortized in terms of the monthly payments. The financial interest is charged to net interest income, and the depreciation is charged to the depreciation expense of each financial year.

The lease's term encompasses non-cancellable periods stipulated within each contract. In the case of a lease contract with indefinite duration, the Bank has determined to assign a span equal to the longest of the non-cancellable period of its lease contracts. Contracts with a non-cancellable period of 12 months or less are treated as short-term leases. Therefore, the related payments are recorded as a straight-line expense. Any change in the lease term or rent is treated as a new measurement of the lease.

In the initial measurement, the Bank measures the right-of-use of the asset at cost. The rent of the lease contracts is agreed in UF and payable in Chilean pesos. According to Circular No 3,649 of the FMC, the monthly UF variation that affects all contracts established in such monetary units should be treated as a new measurement. Therefore, readjustments should be recognized as an amendment to the obligation, and in parallel, the amount of the related asset should be adjusted.

The Bank has not entered into lease agreements with guarantee clauses for residual value or variable lease payments.

**ii. As a lessor**

When the Bank acts as a lessor, it first determines if it corresponds to a financial or operating lease. To do this, the Bank evaluates whether it has substantially transferred all the risks and benefits of the asset. If so, this corresponds to a financial lease. Otherwise, it is an operating lease.

The Bank recognizes lease rentals received on a straight-line income basis over the lease term.

**iii.Third-party financing**

The sum of present values of the lease payments receivable from the lessee is recognized in the line item: 'Loans and receivables from customers' in the Interim Consolidated Statements of Financial Position. This includes the price of the lessee's right-to-call option at the end of the lease term when there is reasonably certain that the lessee will exercise said right. The financial income and expense derived from these contracts are recorded in the Interim Consolidated Statements of Income under 'Interest income' and 'Interest expense', respectively, to achieve a constant return rate over the lease term.

**13. Factoring transactions**

Factored receivables are valued at the amount disbursed by the Bank in exchange for invoices or other commercial instruments representing the credit the transferor assigns to the Bank. The price difference between the amounts disbursed and the actual face value of the loans is recorded as interest income in the Interim Consolidated Statements of Income using the effective interest method over the financing period. When the assignment of these instruments involves no liability on the part of the assignee, the Bank assumes the risks of insolvency of the parties responsible for payment.

**14. Intangible assets**

Intangible assets are non-monetary assets (identifiable separately from other assets) without physical substance arising from legal or contractual rights. The Bank recognizes an intangible asset, whether purchased or self-created (at cost) when the asset's cost can be measured reliably. Additionally, the future economic benefits attributable to the asset are expected to flow into the Bank.

To calculate intangible assets, they are recorded initially at their acquisition or production cost, from which the accumulated amortization and accumulated impairment loss are subtracted.

Internally developed computer software is recorded as an intangible asset if, among other requirements (primarily the Bank's ability to use or sell it), it can be identified and its ability to generate future economic benefits can be demonstrated.

Intangible assets are amortized linearly based on their estimated useful life, defined by default at 36 months. They can be modified if the extent to which the Bank will benefit from its use for a different period than the mentioned above is demonstrated.

Expenditure on research activities is recorded as an expense incurred in the year and cannot be subsequently capitalized.

**15. Non-current assets held for sale** 

***Non-current assets held for sale and discontinued operations***

Per the IFRS 5, 'Non-current assets held for sale and discontinued operations', a non-current asset is classified as held for sale if their carrying amount will be recovered mainly through a sale transaction rather than through continued use.

To apply the above classification, the asset must meet the following requirements:

&nbsp;&nbsp;&nbsp;&nbsp;• It must be available in its current conditions for immediate sale, and a sale must be highly probable.

&nbsp;&nbsp;&nbsp;&nbsp;• For it to be highly probable, the appropriate management level must be engaged in a plan to sell the asset (or group of assets for its disposal). Also, a program to find a buyer and completing said purchase must have been actively initiated.

&nbsp;&nbsp;&nbsp;&nbsp;• Furthermore, the sale should be expected to qualify for recognition as a completed sale within one year of the classification date.

Assets classified in this way will be measured at the lower of their carrying amount or their fair value less costs to sell.

**Assets received or awarded in lieu of payment**

The goods received or awarded in lieu of payment of loans and accounts receivable from clients are recorded, in the case of assets awarded in lieu of payment, at the price agreed between the parties or, conversely, in those cases where there is no agreement between them, by the amount for which the Bank acquired said assets in a judicial auction. In both cases, an independent assessment of the market value of the goods is determined based on the state in which they are acquired.

If the value of loans and receivables exceeds the fair value of the asset received or foreclosed as payment minus selling cost, the difference is recorded in the Interim Consolidated Statements of Income under 'Credit loss expenses'.

These assets are subsequently valued at the lower amount between the initially recorded figure and the net realizable value, which corresponds to their fair value (liquidation value determined through an independent appraisal) minus their respective costs of sale. The differences between the two are recognized in the Interim Consolidated Statements of Income under 'Other operating expenses'.

At the end of each year, the Bank reviews the selling cost of assets received or foreclosed in payment, which is then applied from that date onwards and into the following year. In December 2024, the average cost was estimated at 7.11% of the appraised value (5.67% as of December 31, 2023). In addition, a review of the appraisals by an independent is carried out every 18 months to adjust the fair value of the assets.

In general, these assets are expected to be sold within one year from their date of adjudication. In compliance with Article 84 of the General Banking Law, assets that are not sold within this period are written off in a single installment.

**16. Income and expense recognition**

The most important criteria used by the Bank to recognize its revenues and expenses are summarized as follows:

***a.Interest revenue, interest expense, and similar items***

Interest income, interest expense and similar items are recognized on an accrual basis using the effective interest rate method.

Nevertheless, the Bank ceases to recognize income on an accrual basis when a loan or one of its installments is 90 days overdue. This means that interest, adjustments or commissions are not recognized in the Interim Consolidated Statements of Income unless effectively received.

These interest and readjustments are generally referred to as 'suspended' and are recorded in memorandum accounts, which do not form part of the Interim Consolidated Statements of Financial Position but are reported as part of the supplementary information therein (Note 30 and 31).

Interest incomes of previous 'transactions with suspended accrual' are only recognized again when the debtor is up to date with its obligations.

***b.Commissions, fees and similar items***

Fee and commission income and expenses are recognized in the Interim Consolidated Statements of Income using the criteria set out in IFRS 15, 'Revenue from contracts with customers'.

Under IFRS 15, 'Revenue from contracts with customers', the Bank recognizes revenue when it satisfies its performance obligations by transferring the service (an asset) to the customer. Under this definition, an asset is transferred when the customer obtains control over the asset. The Bank considers the contractual terms and its traditional business practices for determining the transfer price. The transfer price is the amount of compensation the entity expects to be entitled in order to transfer committed goods and services to the customer, excluding amounts collected on behalf of third parties.

The Bank consistently applies the recognition method for each performance obligation, whether it is satisfied over time or at a specific point in time. The main income arising from commissions, fees, and similar items are:

• Credit prepayment fees, which include fees related to customer prepayments of credit operations.

• Fees and commissions on loans with letters of credit, which comprise fees and commissions related to granting loans with letters of credit.

• Fees for lines of credit and overdraft fees, which refer to fees accrued during the year to grant credit lines and current account overdrafts.

• Fees for guarantees and letters of credit, which include fees accrued during the year to grant payment guarantees for real or contingent third-party obligations.

• Card service fees. These refer to fees earned and accrued for the year related to the usage of credit, debit and other cards.

• Account administration fees. These comprise fees incurred for maintenance of current, savings and other accounts.

• Fees and commissions for collections and payments, which include fees and commission income generated by the Bank's collections and payment services.

• Commissions for brokerage and administering securities, which refer to income from commissions generated on brokerage, issuances, administration, and custody of securities.

• Remuneration for the administration of mutual funds, investment funds or others, which comprises commissions from fund management companies separated by type of client (natural or legal person).

• Insurance intermediation and consultancy fees, which include income generated through insurance sales, separated by the type of insurance brokered.

• Fees for financial leasing transaction services, which refer to those financial leasing services in which the Bank acts as a lessor.

• Securitization fees, which include fees for securitization services.

• Fees for financial advisory services, which comprise those involved in advisory services concerning the issuance and placement of financial instruments, restructuring and funding financial liabilities, sale and purchase of companies, and others.

• Other commissions earned, which include income generated by currency exchanges, issuing cashier checks and guarantee slips, trust commissions, foreign trade operations, student loan administration, and other services.

Commission expenses comprise:

• Card transaction fees, which involve commissions generated by credit cards, debit cards and the provision of funds related to the income generated from card service fees.

• License fees of card brands. These are fees paid to the main card brands: credit, debit and provision of funds.

• Other fees for services linked to the credit card system and cards with the provision of funds.

• Expenses for loyalty and merit program obligations for card clients. They refer to expenses related to customer benefit programs related to the use of cards.

• Fees for securities transactions. They comprise fees for deposit, safekeeping and brokerage of securities, investments in mutual funds, stock exchanges, central counterparty and market infrastructure services.

• Other fees for services received. They include securities services, foreign trade, correspondent banking, ATMs and wire transfer fees.

• Fees for clearing high-value payments, which include fees to ComBanc, CCLV, etc.

The relationship between the Segment Note and the disaggregated income is presented in Note 32 Commissions.

The Bank maintains loyalty plans associated with its credit cards, which under IFRS 15 "Revenue from ordinary activities from contracts with customers" have the necessary provisions to meet the delivery of the committed future performance obligations, or said obligations are settled immediately when they are generated.

***c.Non-financial income and expenses***

These are recognized under the criteria established in IFRS 15, 'Revenue from contracts with customers', identifying the performance obligation and when they are satisfied (accrued).

***d.Commissions in the origination of loans***

Financial fees and commissions arising from the origination of loans, mainly origination or research and information gathering fees are accrued and recognized in the Interim Consolidated Statements of Income over the life of the loan.

**17. Provisions for credit risk on loans and receivables and contingent liabilities**

The Bank continuously evaluates the entire portfolio of loans and contingent loans, as established by the FMC, to promptly create sufficient provisions to cover the expected loss linked with the debtors' characteristics and their loans based on payment and subsequent recovery.

The Bank uses the following models established by the FMC and approved by the Board of Directors to assess its loan and contingent loan portfolio:

• Individual assessment of debtors – This applies to debtors recognized as individually significant, that is, with substantial levels of debt, and to those who, even if not significant, are not able to be classified in a group of financial assets with similar credit risk characteristics, and which, due to their size, complexity or level of exposure, require detailed analysis

• Group assessment of debtors - Group assessments are relevant for residential mortgage and consumer credit exposures, in addition to commercial student credit exposures and exposures to debtors that simultaneously meet the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.The Bank has an aggregate exposure to the same counterparty of less than UF 20,000. The aggregate exposure is considered as the gross amount before provisions or other mitigation factors. It also includes residential mortgages in the calculation. Concerning off-balance sheet items (contingent loans), the gross amount is calculated by applying the credit translation factors defined in Chapter B-3 of the CASB.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Each aggregate exposure to a single counterparty does not exceed 0.2% of the total portfolio of loans assesses on a group basis.

Group assessments are suitable for dealing with many transactions, each of a low amount, involving individuals or small companies. The Bank groups debtors with similar credit risk characteristics by associating each group with a certain probability of non-performing and a recovery rate based on a substantiated historical analysis. To this end, the Bank implemented the standard model for mortgage and commercial loans and its internal model for consumer loans.

***A.&nbsp;&nbsp;&nbsp;&nbsp;Provisions for individual assessments***

The individual assessment of a commercial loan debtors is necessary, as established by the FMC, in the case of companies that require detailed knowledge and analysis due to their size, complexity, or level of exposure to the entity.

The analysis of debtors focuses firstly on their credit quality. Then, it classifies them in the risk category corresponding to the debtor and their respective credit operations and contingent loans after assigning them to one of the three portfolio statuses: Normal, Substandard or Impaired. The risk factors used in this analysis are the industry or sector, business situation, partners and management, the company's financial situation and ability to pay, and payment behavior.

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

The portfolio categories and their definitions are as follows:

1. Normal Portfolio includes debtors in which their payment capacity will permit them to pay their obligations and commitments. Evaluations of the current economic and financial environment do not indicate that this will change. The classifications assigned to this portfolio are categories from A1 to A6.

2. Substandard Portfolio includes debtors with financial difficulties or significant deterioration of their payment ability. There is reasonable doubt concerning the future reimbursement of the capital and interest within the contractual terms, with limited ability to meet short-term financial obligations. The classifications assigned to this portfolio are categories B1 to B4.

3. Impaired Portfolio includes debtors and their credits for which repayment is considered remote, as they show a deteriorated or no payment capacity. This portfolio includes debtors who have stopped paying their debts or with obvious indications that they will stop paying, as well as those that require a forced restructuring of debts, reducing the obligation or postponing the term of the principal or interest, and any debtor who is in arrears equal to or greater than 90 days in the payment of interest or capital. The classifications assigned to this portfolio are categories C1 to C6.

**Normal and Substandard Portfolio**

As part of the individual assessment of debtors, the Bank classifies them into the following categories, assigning them a probability of default and severity, which result in the expected loss percentages:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Portfolio** | **Debtor's Category** | **Probability of Non-performance (%)** | **Severity (%)** | **Expected Loss**<br>**(%)** |
| Normal Portfolio | A1 | 0.04 | 90.00 | 0.0360 |
| Normal Portfolio | A2 | 0.10 | 82.50 | 0.0825 |
| Normal Portfolio | A3 | 0.25 | 87.50 | 0.2188 |
| Normal Portfolio | A4 | 2.00 | 87.50 | 1.7500 |
| Normal Portfolio | A5 | 4.75 | 90.00 | 4.2750 |
| Normal Portfolio | A6 | 10.00 | 90.00 | 9.0000 |
| Substandard Portfolio | B1 | 15.00 | 92.50 | 13.8750 |
| Substandard Portfolio | B2 | 22.00 | 92.50 | 20.3500 |
| Substandard Portfolio | B3 | 33.00 | 97.50 | 32.1750 |
| Substandard Portfolio | B4 | 45.00 | 97.50 | 43.8750 |

---

The first step to determine the amount of provisions is to assess the affected exposure, which comprises the book value of loans plus contingent loans, minus the amounts that are feasible to recover through the execution of financial collateral or other collateral covering the operations. To this exposure, the respective loss percentages are applied. In the case of collateral, the Bank must demonstrate that the value assigned to the deduction reasonably reflects the value that can be realized from the disposal of the assets or equity instruments. If the debtor's credit risk is substituted for the guarantor's credit quality, this methodology will only apply if the guarantor or surety is an entity qualified in a category similar to investment grade by a local or international rating agency recognized by the FMC.

Under no circumstances may an endorsed valuable be deducted from the exposure amount, a procedure applicable only in the case of financial guarantees or real collateral.

Notwithstanding the above, the Bank must maintain a minimum provision of 0.5% over loans and contingent loans in the normal portfolio.

***Impaired Portfolio***

The impaired portfolio includes all loans and the entire value of contingent loans of the debtors overdue by 90 days or more on a single payment of interest or principal of any loan at the end of the month. It also includes debtors who have been granted a loan to refinance loans overdue by 60 days or more and debtors who have undergone forced restructuring or partial debt forgiveness.

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

The impaired portfolio excludes: a) residential mortgage loans, with payments overdue less than 90 days; and b) loans to finance higher education granted according to Law No 20,027, that do not fulfil the non-performing conditions outlined in Circular No 3,454 of December 10, 2008.

The provision for an impaired portfolio is calculated by determining the expected loss rate for the exposure, deducting the value of recoverable collateral and deducting the present value of recoveries made through collection services after the related expenses.

Once the expected loss range is determined, the related allowance rate is applied over the exposure amount, including loans and contingent loans related to the debtor.

The allowance rates applied over the calculated exposure are as follows:

---

| | | |
|:---|:---|:---|
| **Classification** | **Estimated range of loss** | **Allowance** |
| C1 | Up to 3% | 2% |
| C2 | Between 3% and 20% | 10% |
| C3 | Between 20% and 30% | 25% |
| C4 | Between 30% and 50% | 40% |
| C5 | Between 50% and 80% | 65% |
| C6 | More than 80% | 90% |

---

All the debtor's loans are maintained in the Impaired Portfolio until its payment ability is normalized, notwithstanding the charge-off of each loan that meets Title II of Chapter B-2 of the CASB. Once the circumstances that led to classification in the Impaired Portfolio have been overcome, the debtor can be removed from this portfolio once all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.The debtor has no obligations overdue with the Bank for 30 consecutive days or more.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.The debtor has not been granted loans to refinance its obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.At least one of the payments includes the amortization of capital.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv.Two payments must already be made if the debtor has made partial loan payments in the last six months.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v.If the debtor must make monthly payments, four consecutive installments must have been paid.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vi.The debtor does not appear to have bad debts in the information provided by the FMC, except for insignificant amounts.

***B.&nbsp;&nbsp;&nbsp;&nbsp;Provisions for group assessments***

Group assessments are relevant for residential mortgage and consumer credit exposures, in addition to commercial student loan exposures and debtor exposures that simultaneously meet the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.The Bank has an aggregate exposure (the exposure on the same Business Group at a consolidated level) to the same counterparty of less than UF 20,000. The aggregate exposure is considered gross of provisions or other mitigating factors and includes residential mortgage loans for its calculation. Concerning off-balance sheet items, the gross amount is calculated by applying the credit translation factors defined in Chapter B-3 of the CASB.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Each aggregate exposure to a single counterparty does not exceed 0.2% of the total portfolio evaluated under group assessment.

To determine provisions, group assessments require the creation of groups of loans with homogeneous qualities in terms of the type of debtors and contracted loan terms in order to establish, using technically sound estimates and prudential criteria, the payment behavior of the group and the recoveries of its non-performing loans. This is done using a model based on the characteristics of the debtors, payment history, outstanding loans and delinquency, among other relevant factors.

The Bank uses methodologies to determine credit risk based on internal and/or standard models to estimate provisions for the group-assessed portfolio. These include commercial loans for debtors who are not individually assessed, residential mortgage loans and consumer loans (including installment loans, credit cards and overdraft facilities). This methodology helps to independently identify the portfolio's performance one year ahead and determines the provision necessary to cover the losses arising in the period of one year from the balance sheet date.

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

Clients are segmented according to their internal and external characteristics into groups or profiles to differentiate the risk of each portfolio in a more appropriate and orderly manner (client-portfolio model). This is known as the profile assignment method.

The profile assignment method is based on a statistical construction method, constituting a relationship through a logistic regression between variables such as non-performance, external credit behavior, sociodemographic variables, and a response variable that determines a customer's risk, which in this case is non-performance equal to or greater than 90 days. Hence, common profiles are established and assigned a Probability of Non-Performance (PNP), also known as a Probability of Default (PD), and a recovery rate based on a substantiated historical analysis known as Loss Given Default (LGD).

Therefore, once the client has been assigned a profile and a PNP and a LGD has been set for their type of loan, the exposure at default (EXP) is calculated. This exposure includes the book value of the loans and receivables from the customer, plus contingent loans, minus any amount that can be recovered by activating collateral (for loans other than consumer loans).

Notwithstanding the above, in establishing provisions related to mortgage and commercial loans, the Bank must recognize minimum provisions according to standard methods established by the FMC for those types of loans. While this is considered a conservative minimum base, it does not relieve the Bank of its responsibility to have its own internal methodologies for determining adequate provisions to cover the portfolio's credit risk. Provisions must be made considering the higher value obtained between the respective standardized method and the internal method.

**Standard method of provisions for group assessments**

**1. Residential mortgage portfolio**

Under the CASB, the Bank applies the standard provisioning method for residential mortgages. Under this method, the expected loss factor applicable to the number of residential mortgage loans will depend on the delinquency of each loan and the ratio, at the end of each month, between the outstanding principal amount of each loan and the value of the mortgage collateral (loan-to-value or LTV) that covers it.

The relevant provisioning factor according to delinquency and LTV is as follows:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| **LTV Range** | **Days past due at month-end** | **0** | **1-29** | **30-59** | **60-89** | **Impaired portfolio** |
| LTV ≤ 40% | PNP(%) | 1.0916 | 21.3407 | 46.0536 | 75.1614 | 100 |
| LTV ≤ 40% | LGD (%) | 0.0225 | 0.0441 | 0.0482 | 0.0482 | 0.0537 |
| LTV ≤ 40% | EL (%) | 0.0002 | 0.0094 | 0.0222 | 0.0362 | 0.0537 |
| 40% < LTV ≤ 80% | PNP(%) | 1.9158 | 27.4332 | 52.0824 | 78.9511 | 100 |
| 40% < LTV ≤ 80% | LGD (%) | 2.1955 | 2.8233 | 2.9192 | 2.9192 | 3.0413 |
| 40% < LTV ≤ 80% | EL (%) | 0.0421 | 0.7745 | 1.5204 | 2.3047 | 3.0413 |
| 80% < LTV ≤ 90% | PNP(%) | 2.515 | 27.93 | 52.58 | 79.6952 | 100 |
| 80% < LTV ≤ 90% | LGD (%) | 21.5527 | 21.66 | 21.92 | 22.1331 | 22.231 |
| 80% < LTV ≤ 90% | EL (%) | 0.5421 | 6.0496 | 11.5255 | 17.639 | 22.231 |
| LTV > 90% | PNP(%) | 2.74 | 28.43 | 53.08 | 80.3677 | 100 |
| LTV > 90% | LGD (%) | 27.2 | 29.03 | 29.59 | 30.1558 | 30.2436 |
| LTV > 90% | EL (%) | 0.7453 | 8.2532 | 15.7064 | 24.2355 | 30.2436 |

---

LTV= (Loan-to-Value Ratio) unpaid loan principal/value of the mortgage collateral.

EL = Expected loss

This standardized approach will also be applied to residential leasing transactions, following the same criteria described above and considering the leased asset value equivalent to the amount of the mortgage collateral.

If the same debtor holds more than one residential mortgage loan with the Bank and one is overdue by 90 days or more, all these loans will be assigned to the impaired portfolio, with provisions calculated for each according to their respective LTV percentages.

In the case of residential mortgage loans linked to housing and subsidy programs of the State of Chile, provided that they are contractually covered by the auction insurance supplied by the latter, the provisioning percentage may be weighted by a loss mitigation (LM) factor, which depends on the LTV percentage and the value of the house in the deed of sale (V). Therefore, the LM factors to be applied to the corresponding provisioning percentage are presented in the table below:

**2.&nbsp;&nbsp;&nbsp;&nbsp;Commercial loan portfolio**

Following the CASB, the Bank applies the standard model of provisions for commercial loans in the group portfolio, depending on whether it corresponds to commercial leasing, student or other commercial loans.

Before implementing the standard method, the Bank used internal models to determine provisions for commercial loans assessed on a group basis.

***i. &nbsp;&nbsp;&nbsp;&nbsp;Commercial leasing operations***

For these operations the provision factor must be applied to the current value of commercial leasing operations (including the purchasing option at the end of the lease). Therefore, it will depend on the delinquency of each operation, the type of leased asset and the relationship, at the closing of each month, between the current value of each operation and the value of the leased asset (LTV), as indicated in the following tables:

---

| | | |
|:---|:---|:---|
| **Probability of Non-Performance (PNP) applicable according to delinquency and type of asset (%)** | **Probability of Non-Performance (PNP) applicable according to delinquency and type of asset (%)** | **Probability of Non-Performance (PNP) applicable according to delinquency and type of asset (%)** |
| **Days past due at the end of the month** | **Type of asset** | **Type of asset** |
| **Days past due at the end of the month** | **Real estate** | **Non-real estate** |
| 0 | 0.79 | 1.61 |
| 1-29 | 7.94 | 12.02 |
| 30-59 | 28.76 | 40.88 |
| 60-89 | 58.76 | 69.38 |
| Non-performing portfolio | 100 | 100 |

---

---

| | | |
|:---|:---|:---|
| **Loss Given Default (LGD) applicable by PVB range and type of asset (%)** | **Loss Given Default (LGD) applicable by PVB range and type of asset (%)** | **Loss Given Default (LGD) applicable by PVB range and type of asset (%)** |
| **LTV range (\*)** | **Real estate** | **Non-real estate** |
| LTV ≤ 40% | 0.05 | 18.2 |
| 40% < LTV ≤ 50% | 0.05 | 57 |
| 50% < LTV ≤ 80% | 5.1 | 68.4 |
| 80% < LTV ≤ 90% | 23.2 | 75.1 |
| LTV > 90% | 36.2 | 78.9 |

---

(\*) LTV= Current value of operation/leased asset value

The LTV ratio will be determined considering the appraisal value, expressed in UF for real estate and pesos for non-real estate, recorded at the time of granting the respective loan, considering any situations that may be causing temporary rises in the asset price at that time.

***ii.&nbsp;&nbsp;&nbsp;&nbsp;Student loans***

For these operations, the provision factor should be applied to the student loan and the exposure of the contingent loans, when applicable. The determination of this factor depends on the type of student loan and the enforceability of the payment of capital or interest at the end of each month. When payment is due, the factor will also depend on the delinquency of the loan. For the loan classification, a distinction is made between those granted for financing higher studies under Law No 20,027 (CAE) and, on the other hand, the CORFO guaranteed loans or other student loans.

---

***iii.&nbsp;&nbsp;&nbsp;&nbsp;Generic commercial loans and factoring***

For factoring transactions and other commercial loans, the provisioning factor, applicable to the amount of the loan and the contingent loan exposure, will depend on the delinquency of each transaction and the ratio at the end of each month between the debtor's obligations to the Bank and the value of the collateral (LTVC) securing them, as indicated in the following tables:

---

| | | | |
|:---|:---|:---|:---|
| Probability of Non-Performance (PNP) applicable according to delinquency and LTVC range (%) | Probability of Non-Performance (PNP) applicable according to delinquency and LTVC range (%) | Probability of Non-Performance (PNP) applicable according to delinquency and LTVC range (%) | Probability of Non-Performance (PNP) applicable according to delinquency and LTVC range (%) |
| Days past due at month-end | Guarantee | Guarantee | No collateral |
| Days past due at month-end | LTVC ≤ 100% | LTVC > 100% | No collateral |
| 0 | 1.86 | 2.68 | 4.91 |
| 1-29 | 11.6 | 13.45 | 22.93 |
| 30-59 | 25.33 | 26.92 | 45.3 |
| 60-89 | 41.31 | 41.31 | 61.63 |
| Non-performing portfolio | 100 | 100 | 100 |

---

---

| | | | |
|:---|:---|:---|:---|
| **Loss Given Default (LGD) applicable according to LTVC range (%)** | **Loss Given Default (LGD) applicable according to LTVC range (%)** | **Loss Given Default (LGD) applicable according to LTVC range (%)** | **Loss Given Default (LGD) applicable according to LTVC range (%)** |
| **Collateral**<br>**(with/without)** | **LTVC Range** | **Factoring and other commercial loans without responsibility of assignor** | **Factoring with responsibility of assignor** |
| Collateral | LTVC ≤ 60% | 5 | 3.2 |
| Collateral | 60% < LTVC ≤ 75% | 20.3 | 12.8 |
| Collateral | 75% < LTVC ≤ 90% | 32.2 | 20.3 |
| Collateral | 90% < LTVC | 43 | 27.1 |
| No collateral | No collateral | 56.9 | 35.9 |

---

The collateral used to calculate the LTVC ratio of this method may be of a specific or general nature or those that are simultaneously specific and general in nature. However, a collateral can only be considered if, according to the respective coverage clauses, it was set in the first degree of preference in favor of the Bank and it only guarantees the debtor's credits concerning which it is attributed (not shared with other debtors). The invoices assigned in the factoring operations, or the guarantees linked to mortgage loans, regardless of their coverage clauses, will not be considered in the calculation.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

 **NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

The following considerations must be taken into account when calculating the LTVC ratio:

i.Transactions with specific guarantees: those in which the debtor provided specific guarantees for generic commercial loans and factoring. The LTVC ratio is calculated separately for each secured transaction as the division between the loan amount and the contingent loan exposure over the collateral's value.

ii.Transactions with general guarantees: when the debtor is granted general or general and specific guarantees, the Bank calculates the corresponding LTVC jointly for all generic commercial loans, factoring and operations not contemplated in the above paragraph i), as the division between the sum of the amounts of loans and contingent loan exposures over the general or specific guarantees that, according to the scope of the remaining coverage clauses, protect the loans considered in the numerator of the ratio mentioned above.

The amounts of collateral used in the LTVC ratio in (i) and (ii) should be determined according to the:

• The collateral's last valuation, whether in its appraisal or fair value, depending on the type of collateral in question. The criteria in Chapters 7-12 of the Updated Collection of Banking Regulations (from now on: UCBR) should be considered to determine fair value.

• Possible situations that could be causing temporary rises in the values of the collaterals.

• Limits to the amount of coverage established in their respective clauses.

***3. Consumer loan portfolio***

Expected Loss (EL), which corresponds to the product of Probability of Default (PD) and Loss Given Default (LGD), will be uniformly applied to all consumer loans and contingent loans that the borrower holds with the bank and its subsidiaries in Chile, including consumer leasing operations. In the case of contingent operations, the exposure measure must be calculated in accordance with the provisions set forth in Chapter B-3 of the CASB issued by the FMC, the latest update which was published on March 6, 2024 (Circular No. 2,346).

To define the value of the PNP, the following factors must be calculated for each borrower:

• Delinquency level at the bank: this corresponds to the maximum delinquency level (in days) in the consumer portfolio, including consumer leasing operations, that the borrower has with the bank at the end of the month for which provisions are being determined. For clients with more than one operation, the highest value among them will be used. This variable must be measured across all entities that make up the institution's global consolidated level.

• 30-day delinquency in the financial system: this indicates whether the borrower has at least one direct debt with delinquency equal to or greater than 30 days in any of the 3 months prior to the provisioning month. To construct this variable, the borrower's delinquency across all known credit providers should be considered, using the debtor list compiled by the FMC, as well as the Bank's own global consolidated data and various financial products. Only debts with communication restrictions under Law No. 19,628 on the Protection of Private Life should be excluded.

• Ownership of a mortgage loan: this variable identifies whether the borrower has a current residential mortgage loan in the financial system. For this, the Bank must use the most recent available information at the time provisions are calculated, considering the debtor list compiled by the FMC, in addition to the Bank's own global consolidated data.

Based on the above variables, the PNP is determined according to the following table:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **With a residential mortgage loan in the system** | **With a residential mortgage loan in the system** | **Without a residential mortgage loan in the system** | **Without a residential mortgage loan in the system** |
| **Maximum level of delinquency in the month and bank (interval in days that includes extremes)** | **No over due loan loans of more than 30 days in the system** | **With over due loan loans of more than 30 days in the system** | **No over due loan loans of more than 30 days in the system** | **With over due loan loans of more than 30 days in the system** |
| **0 and 7** | 3.3% | 14.6% | 6.6% | 19.8% |

If the borrower is in default (>90 days), the assigned PNP will be 100%.

To determine the value of the LGD, it must be identified whether the borrower has a residential mortgage loan in the system (as defined for PNP), and the type of loan involved. The LGD to be used is defined in the table below:

---

| | | | |
|:---|:---|:---|:---|
| | **Leasing operations and auto loans** | **Installments loans** | **Credit card, overdraft and other consumer loans** |
| **With residential mortgage loan in the system** | 33.2% | 47.7% | 49.5% |
| **Without residential mortgage loan in the system** | 33.2% | 56.6% | 60.3% |

---

The assignment of the LGD value should follow these guidelines:

&nbsp;&nbsp;&nbsp;&nbsp;• "Leasing operations and auto loans" include loans whose purpose is to finance the acquisition of personal-use vehicles, which are pledged as collateral in favor of the institution. This category also includes financial consumer leasing operations recorded under item 14800 04 00 of the CASB of the FMC.

&nbsp;&nbsp;&nbsp;&nbsp;• "Installment Loans" correspond to those recorded under item 14800 01 00 of Chapter C-3 of the CASB (Consumer loans in installments), provided they were granted following the signing of a promissory note that clearly states the principal amount, term, interest rate, and number of installments, without a predefined use of the funds (unrestricted use by the borrower), and do not fall into the previous category.

&nbsp;&nbsp;&nbsp;&nbsp;• If a loan does not fall under either of the two definitions above but is classified under line 14800 00 00 (Consumer loans) of the CASB, the LGD value assigned to the "Credit cards, credit lines, and other consumer loans" category should be applied.

***C. &nbsp;&nbsp;&nbsp;&nbsp; Provisions for contingent loans***

Contingent loans are transactions or commitments in which the Bank assumes a credit risk by obliging itself vis-à-vis third parties upon a future event to make a payment or a disbursement to be recovered from its clients.

To calculate the provisions as indicated in Chapter B-1 of the CASB, the amount of exposure to be considered shall be equal to the percentage of the contingent claim amounts indicated below:

---

| | |
|:---|:---|
| **Type of loan** | **Credit Translation Factors (CTF)** |
| Immediately repayable unrestricted credit lines | 10% |
| Contingent loans linked to student loan (CAE) | 15% |
| Letters of credit for goods movement operations | 20% |
| Other unrestricted credit lines | 40% |
| Debt purchase commitments in local currencies abroad | 50% |
| Transactions related to contingent events | 50% |
| Guarantees and sureties | 100% |
| Other credit commitments | 100% |
| Other contingent loans | 100% |

---

In the case of transactions with clients with non-performing loans, such exposure shall always equal 100% of their contingent loans.

***D.&nbsp;&nbsp;&nbsp;&nbsp;Collateral and credit enhancements***

Collateral is only considered in calculating provisions when they are legally established and when the conditions allowing their eventual activation or settlement in the Bank's favor are met. Collateral valuation (mortgages or pledges) reflects the net cash flow obtained from selling goods or equity instruments, or from capital minus estimated expenses in the event of a debtor's non-performance.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

For mortgages and pledges on goods, the Bank undertakes analyses that reflect the relationship between the prices obtained in an eventual settlement and their appraisal or foreclosure values. Nevertheless, the valuations of mortgages and other goods received are based on valuations carried out by independent professionals, while maintenance and transaction costs are based on historical data from at least 3 years prior. The Bank has the necessary collateral revaluation standards in place.

Financial collateral, measured through fair value adjustments, may only be deducted from credit risk exposures when they are provided to secure the performance of the credits concerned. The adjusted fair value is obtained by applying the interest rate and currency volatility discount factors established by the FMC and subtracting settlement costs. Determining provisions in the case of leased assets considers the value obtained on the disposal of the leased assets, considering the impairment that these may present, and the expenses related to their redemption and liquidation or eventual relocation. Determining provisions for factoring loans considers that the counterparty is the assignor of the documents endorsed to the Bank when the factoring is with liability and the debtor when the assignment is without liability of the assignor.

***E.&nbsp;&nbsp;&nbsp;&nbsp;Additional provisions***

According to FMC regulation, banks can establish provisions over the already described limits to protect themselves from the risk of non-predictable economic fluctuations that could affect the macroeconomic environment or a specific economic sector. As set out in number 9 of Chapter B-1 of the CASB of the FMC, these provisions shall be reported on the liability side in the same way as provisions on contingent claims.

***F. Provisions related to financing with FOGAPE guarantee Covid-19***

The FMC requested that specific provisions be determined for loans secured by the FOGAPE Covid-19 guarantee, for which the expected loss must be determined. This is done by estimating the risk of each transaction, dismissing the guarantor's credit quality substitution, and following the appropriate individual or group analysis method per the clauses of the CASB Chapter B-1. This calculation must be made on an aggregate basis, grouping all transactions to which the same deductible percentage is applicable.

Hence, the total expected loss resulting from the aggregate calculation of each transaction group must be compared with the total deductible corresponding to them. When the expected loss of the transactions of a group with the same deductible percentage is determined to be equal to or less than the aggregate deductible, the provisions are set without considering the FOGAPE Covid-19 guarantee, that is, without replacing the creditworthiness of the direct debtor for that of the guarantor. When they surpass the aggregate deductible, the provisions shall be determined using the substitution method set out in the CASB paragraph 4.1(a) of Chapter B-1 and shall be recognized in accounts separate from commercial, consumer and residential mortgage provisions.

***G. Provisions established for credit risk as a result of supplementary prudential requirements***

This corresponds to the provisions for credit risk required by the Committee's prudential instructions in relation to credit risk management assessments under Chapters 1-13 of the UCBR and that do not qualify as provisions established per the definitions in Chapter B-1 of the CASB.

***H.&nbsp;&nbsp;&nbsp;&nbsp;Distressed loans and suspension of accrual***

Distressed loans, in the case of individual assessment, is made up of the loans classified in the Impaired Portfolio plus categories B3 and B4 of the Substandard Portfolio. In the case of group assessment, it includes the credits of the Impaired Portfolio.

The Bank ceases to recognize income on an accrual basis in the Interim Consolidated Statements of Income when the loan or one of its installments is 90 days overdue. From the date interest is suspended until they are no longer impaired, loans shall not be credited with interest, adjustments or fees in the Interim Consolidated Statements of Financial Position. No income from such loans shall be recognized in the Interim Consolidated Statements of Income unless received.

***I.&nbsp;&nbsp;&nbsp;&nbsp;Charge-offs***

As a general rule, charge-offs should be applied when the contractual rights to the cash flows expire.

The charge-offs in question refer to the derecognition in the Interim Consolidated Statements of Financial Position of the assets corresponding to the respective transaction, including that part which may not be overdue in the case of a loan payable in installments or a leasing transaction (there are no partial charge-offs). This includes overdue, past-due and current installments, with the term corresponding to the time elapsed since the date on which payment of all or part of the obligation is in delinquency.

As of September 30, 2025, and 2024, and as of December 31, 2024

 **NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

Charge-offs are always booked against the credit risk provisions set up under Chapter B-1 of the CASB, regardless of the reason for the write-off.

Charge-offs should be carried out in the following circumstances, whichever occurs first:

1. Based on all available information, the Bank concludes that it will not obtain flows from the loans recorded as an asset.

2. When an unencumbered claim is 90 days old since it was registered as an asset.

3. Upon expiration of the statute of limitations for actions to claim collection through an enforceable judgment or at the time of the rejection or abandonment of the enforcement of the title by an enforceable court decision.

4. When the period of arrears of a transaction reaches the time limit for charge-offs set out below:

---

| | |
|:---|:---|
| **Type of loan** | **Term** |
| Consumer loans with or without collateral | 6 months |
| Other transactions without collateral | 24 months |
| Commercial loans with collateral | 36 months |
| Mortgage loans | 48 months |
| Consumer leasing | 6 months |
| Other non-mortgage leasing transactions | 12 months |
| Mortgage leasing (household and business) | 36 months |

---

***J.&nbsp;&nbsp;&nbsp;&nbsp; Recovery of loans previously written off and receivables from clients***

Subsequent payments on written-off transactions shall be recognized in the profit or loss statement as recoveries of charged-off loans. When a recovery is perceived in the form of an asset received in lieu of payment, the income is recognized as the amount by which they are incorporated into the asset under the provisions of the Chapter of the CASB regarding Assets Received or Awarded in Lieu of Payment.

The same approach is followed if the leased goods are recovered after a leased transaction is written off when such goods are incorporated as an asset.

**18. Impairment of financial assets other than loans and receivables and contingent loans**

The Bank applies IFRS 9 'Financial Instruments' to determine the impairment of financial assets measured at fair value through other comprehensive income and financial assets at amortized cost other than loans and contingent receivables.

The estimate involves calculating the potential credit losses that could be observed on a financial instrument due to differences between the future cash flows under the original contract and the cash flows expected to be received, always ensuring at all times that the results obtained are appropriate to the reality of the transactions, the current economic environment and the available forward-looking information.

This model uses a dual measurement approach in which the impairment provision is measured as follows:

• Credit loss expected at 12 months: it represents expected credit losses arising from default events on a financial instrument that may arise within 12 months from the reporting date.

• Lifetime expected credit loss: it represents the expected credit losses arising from default events over the expected life of a financial instrument.

At each reporting date, an entity must measure the provision as equal to the 'lifetime expected credit loss' if the credit risk on that financial instrument has increased significantly since initial recognition. Otherwise, if the credit risk of a financial instrument has not increased significantly at the reporting date since initial recognition, an entity shall measure the loss allowance for that financial instrument at an amount equal to 'expected credit loss over the next 12 months'.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

 **NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

When making such an assessment, an entity compares the default risk of a financial instrument at the reporting date with that of its initial recognition, as well as considering reasonable and tenable information made available without unnecessary cost or effort, indicating the growth of credit risk since its initial recognition (on a group or individual basis). Based on changes in credit quality, IFRS 9 describes a 'three-step' impairment model according to the following diagram:

---

| | | |
|:---|:---|:---|
| **Change in credit quality since initial recognition** | **Change in credit quality since initial recognition** | **Change in credit quality since initial recognition** |
| **Phase 1** | **Phase 2** | **Phase 3** |
| Initial recognition | Significant increase in credit risk since initial recognition | Credit-impaired assets |
| Credit loss expected in 12 months | Lifetime credit loss | Lifetime credit loss |

---

Reasonable and tenable information refers to information readily available at the reporting date without unreasonable cost or effort, including information about past events, current conditions and forecasts of future economic conditions. When contractual payments are overdue by 30 days or more, the Bank considers that the credit risk of a financial asset has increased significantly, but this is not the only indicator.

**Measurement of expected credit loss**

Expected credit loss estimates the weighted probability of credit losses over the financial instrument's expected life, that is, the present value of all cash shortfalls. The three components of the measurement of expected credit loss are:

• **PNP:** The probability of default estimates the probability of non-performance over a given time frame.

• **LGD**: Loss-given default estimates the loss that would occur in the event of a default at a given time.

• **EAD:** Exposure at default is an estimate of the exposure at a future date of non-performance, considering expected exposure changes after the reporting date, including repayments of principal and interest, whether contractually scheduled or otherwise, and interest on defaults.

The parameters used for the calculation of impairment provisions were developed based on the structure of the internal models used and take into account the experience acquired in the regulatory and management areas, as well as the stages in which each financial asset is classified, including forward-looking information, point-in-time (PIT) view, multiple scenarios, calculation of losses for the entire life of the operation through lifetime PNP, among others. Collateral and other credit enhancements are considered to measure expected credit loss.

**Determination of a significant increase in risk**

For the classification in phase 2, an assessment of whether there is a significant increase in credit risk (SICR) from the initial recognition of the transactions is undertaken. For this, a series of principles that ensure that all financial instruments are subject to this assessment is used, which considers the particularities of each portfolio and type of product based on various quantitative and qualitative indicators. All of this is subject to the expert judgment of analysts, who set the thresholds under appropriate management integration and implement it under the approved governance.

The judgment and criteria used to establish thresholds are based on several principles. The principles are as follows:

• Universal: all financial instruments with a credit rating must be assessed for their potential SICR.

• Proportional: the definition of the SICR should consider each portfolio's particularities.

• Materiality: its implementation should also be consistent with each portfolio's relevance to avoid unnecessary cost or effort.

• Holistic view: the selected approach should combine the most relevant aspects of credit risk (i.e. quantitative and qualitative).

• Application of IFRS 9: the approach should consider the features of IFRS 9, focusing on a comparison with credit risk at initial recognition and considering forward-looking information.

• Risk management integration: criteria should be consistent with those metrics considered in day-to-day risk management.

-Documentation: Appropriate documents must be prepared

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

To classify a financial instrument in phase 2, we consider the following criteria:

• Quantitative criteria: changes in the risk of a default occurring over the expected life of the financial instrument are analyzed and quantified relative to its level of credit risk at inception. For this purpose, quantitative thresholds have been defined for the portfolios. These thresholds can be expressed as an absolute or relative increase in the probability of default.

◦ Qualitative criteria: using expert judgment, we use various indicators aligned with those used in ordinary credit risk management (defaults over 30 days, refinancing, etc.).

◦ Definition of default: this definition entails the application of various criteria to classify exposures as phase 3, including transactions in default for 90 consecutive days or identifying other criteria that demonstrate that the counterparty can meet all of its financial obligations.

◦ Expected life of the financial instrument: we estimate the expected life of a financial instrument considering all contractual terms (e.g. prepayments, duration, repurchase agreements, etc.).

**Recognition of expected credit loss**

An entity shall recognize in its financial results a gain or loss caused by value impairment as the amount of the expected credit loss (or releases) by which the value is adjusted given the losses that have occurred by the reporting date to capture the amount that requires recognition accurately.

For assets measured at fair value through other comprehensive income, the book value of the instruments is understood as the fair value. Therefore, the recognition of impairment does not affect the carrying amount of such instruments and is reflected as a movement between other comprehensive income (a deduction from fair value) and results at each reporting date.

In the case of assets measured at amortized cost, impairment is presented through a complementary account that reduces the asset's value.

**19. Impairment of non-financial assets**

The Bank's non-financial assets are reviewed at each reporting date of the Interim Consolidated Financial Statements for indications of impairment (i.e., when the carrying amount exceeds the recoverable amount). If such indications exist, the asset's recoverable amount is estimated to determine the extent of the impairment loss.

The recoverable amount is the higher of fair values minus disposal costs and value in use. In assessing value in use, estimates of cash inflows or outflows shall be discounted to present value using the pre-tax discount rate that reflects the current market assessment of the time value of money and the specific risks for which estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset is estimated to be lower than its carrying amount, the carrying amount is reduced to the recoverable amount. The impairment loss is recognized immediately in profit or loss.

In relation to other assets, impairment losses recognized in prior periods are evaluated at each reporting date for any indication that the loss has decreased and should be reversed. The increase in the carrying value of an asset other than goodwill attributed to a reversal of the impairment loss will not exceed the carrying amount that could have been obtained (net of amortization or depreciation) if an impairment loss had not been recognized for said asset in previous periods. The impairment loss recognized in goodwill will not be reversed.

**20. Provisions, contingent assets and liabilities**

Provisions are liabilities whose amount or maturity are uncertain. These provisions are recognized in the Interim Consolidated Statements of Financial Position when all the following requirements are met:

i. It is a current obligation (legal or constructive) as a result of past events and,

ii.as of the publication date of the financial statements, the Bank will probably have to expend resources to settle the obligation and;

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

iii.the amount of these resources can be reliably measured.

Contingent assets or contingent liabilities encompass all potential rights or obligations arising from past events. These are only confirmed if one or more uncertain future events occurs, which are not within the Bank's control.

The Interim Consolidated Financial Statements reflect all significant provisions for which the probability of meeting the obligation is estimated to be more likely than not. Provisions are quantified using the best available information regarding the consequences of the event giving rise to them and are reviewed and adjusted at the end of the accounting period. Provisions are used when the liabilities for which they were originally recognized are settled. Partial or total reversals are recognized when such liabilities cease to exist or are reduced.

Provisions are classified according to the obligation covered as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions for employee benefit obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions for lawsuits and litigations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions for operational risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions for mandatory dividends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions for contingent loan risks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions for contingencies.

**21. Income tax and deferred taxes**

The Bank recognizes, where appropriate, deferred tax assets and liabilities for the estimated future tax effects attributable to differences between the carrying amounts of assets, liabilities and their tax bases. Deferred tax assets and liabilities are calculated using the tax rate applied in the year the deferred tax assets and liabilities are realized or settled according to current tax legislation. The future effects of tax legislation or tax rate changes are recognized in deferred taxes from when the law approving such changes is published.

Current tax assets relate to provisional payments in excess of the provision for income tax or other income tax credits, such as training expenses or donations to universities. In addition, the monthly provision payments to be recovered for profits absorbed by tax losses should be included. In the case of liabilities, they correspond to the provision for income tax calculated based on the tax results for the period, minus the mandatory or voluntary provisional payments and other credits applied to this obligation.

For presentation in the Interim Consolidated Statements of Financial Position, in accordance with IAS12, the tax position at the tax entity level should be offset, as appropriate, and subsequently, the net balances per tax entity should be added at the consolidated level.

**22. Employee benefits**

**1. Post-employment benefits – Defined Benefit Plan:**

According to the current collective labor covenant and other agreements, Banco Santander-Chile has an additional benefit available for its main executives, consisting of a pension plan, aiming for them to have the necessary funds for a supplementary pension upon retirement.

***Plan Features:***

The main features of the Post-Employment Benefits Plan promoted by the Banco Santander-Chile are:

i.Aimed at the Bank's upper management.

ii.The general requirement is that the beneficiary must still hold their position within the Bank by the time they turn 60 years old.

iii.The Bank will contract a mixed collective insurance policy (life and savings) for each executive, with the contracting party and beneficiary being the Group company to which the executive belongs. Periodic contributions will equal the amount each manager commits to their voluntary contribution plan.

iv.The Bank will be responsible for granting the benefits directly.

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

To determine the present value of the defined benefit obligation and the current service cost, the projected unit credit method is used. The components of defined benefit cost include:

&nbsp;&nbsp;&nbsp;&nbsp;• Current and past service costs are recognized in profit or loss for the period.

&nbsp;&nbsp;&nbsp;&nbsp;• Net interest over the net defined benefit liability (asset), recognized in profit or loss for the period.

&nbsp;&nbsp;&nbsp;&nbsp;• The new net defined benefit liability (asset) measurements include: (a) actuarial gains and losses; (b) the performance of the plan's assets, and (c) changes in the effect of the asset ceiling, which are recognized in other comprehensive income.

The net defined benefit liability (asset) is the deficit or surplus, calculated as the difference between the defined benefit obligation's present value minus the plan assets' fair value.

The plan assets comprise the insurance policies contracted by the Bank through an unrelated third party. These assets are held by an entity legally separated from the Bank and exist solely to pay employees their benefits.

The Bank recognizes the present service cost and the net interest in the item 'Personnel wages and expenses' in the Interim Consolidated Statements of Income. The plan's structure does not generate actuarial gains or losses. The plan's performance is established and fixed during the period; consequently, there are no changes to the asset's ceiling. Accordingly, there are no amounts recognized in other comprehensive income.

The post-employment benefits obligation recognized in the Interim Consolidated Statements of Financial Position, represents the deficit or surplus in the defined benefit plans of the Bank. Any surplus resulting from the calculation is limited to the present value of any economic benefits available regarding the plan's reimbursements or reductions to future contributions.

When employees abandon the plan before meeting the requirements to become eligible for the benefit, the Bank's contributions decrease.

**ii.Severance payments:**

Severance payments for years of employment are recorded only when they effectively occur or upon the availability of a formal and detailed plan in which the fundamental modifications to be made are identified, provided that such plan has already started to be implemented, its principal features have been publicly announced, or objective facts about its activation are known.

**iii.Cash-settled share-based payments**

The Bank allocates cash-settled share-based payments to certain executives of the Bank and its Subsidiaries under IFRS 2. Accordingly, the Bank measures the services received and the obligation incurred at fair value.

Until the obligation is settled, the Bank calculates the fair value at the end of each reporting period and at the date of settlement, recognizing any change to fair value in the income statement for the period.

23. Use of Estimates

Preparing the Interim Consolidated Financial Statements requires the Bank's Management to make estimates and assumptions that affect the application of the accounting standards and the reported values of assets, liabilities, revenues and expenses. Accordingly, actual results may differ from these estimates.

In certain cases, the generally accepted accounting standards require that assets or liabilities be recorded or disclosed at their fair value. The fair value is the price received to sell an asset or paid to transfer a liability in an orderly transaction between informed market participants at the measurement date. When available, quoted market prices in active markets have been used for measurement. When the trade prices of an active market are not available, the Bank estimates such values based on the best information available, including internal modelling and other valuation techniques.

The Bank has established provisions to cover potential credit loss per the regulations issued by the FMC. These allowances must be regularly reviewed, considering factors such as changes in the nature and volume of the loan portfolio, trends in forecasted portfolio quality, credit quality, and economic conditions that may adversely affect the borrowers' ability to pay. Increases in the allowances for loan loss are reflected as 'Provisions for loan loss' in the Interim Consolidated Statements of Income.

**NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued**

Loans are written off when the contractual rights for the cash flows expire. Nevertheless, the Bank will charge off per Title II of Chapter B-2 of the CASB issued by the FMC for loans and accounts receivable from clients. Charge-offs are recorded as a reduction of credit risk provisions.

The Bank's Management regularly reviews the relevant estimates and assumptions to calculate provisions quantifying certain assets, liabilities, revenues, expenses, and commitments. Revised accounting estimates are recorded in the period the estimate is revised and in any future period affected.

These estimates are based on the best available information and mainly refer to the following:

• Allowances for loan loss (Notes N° 13 and 41).

• Impairment loss on certain assets (Notes N°11, 13, 15, 16, 17, 39 and 40).

• The useful lives of tangible and intangible assets (Notes N° 15, 16 and 17).

• The fair value of assets and liabilities (Notes N° 8, 11, 12, 21 and 44).

• Commitments and contingencies (Note N° 29).

• Current and deferred taxes (Note N°18).

**24. Earnings per share**

Basic earnings per share are calculated by dividing the net income attributable to the equity holders of the Bank by the weighted average number of shares outstanding during the reported period. Diluted earnings per share are calculated similarly to basic earnings, but the weighted average number of outstanding shares is adjusted to consider the potential diluting effect of stock options, warrants, and convertible debt. As of September 30, 2025, and 2024, and as of December 31, 2024, the Bank did not hold any instruments that have a dilutive effect on equity.

**25. Temporary acquisition (assignment) of assets**

Purchases (sales) of financial assets under non-optional repurchase agreements at a fixed price (repos) are recorded in the Interim Consolidated Statements of Financial Position as a financial assignment (receipt) based on the nature of the debtor (creditor) under 'Deposits in the Central Bank of Chile', 'Deposits in financial institutions' or 'Loans and receivables from customers' ('Deposits from Central Bank of Chile', 'Deposits from financial institutions' or 'Deposits').

The difference between the purchase and sale prices is recorded as financial interest over the contract's life.

**26. Assets and investment funds managed by the Bank**

The assets managed by the different companies that form part of the Bank's consolidation perimeter (Santander S.A. Sociedad Securitizadora) that are owned by third parties are not included in the Interim Consolidated Statements of Financial Position. The commissions generated by this activity are included in the balance of 'Fee and commission income' in the Interim Consolidated Statements of Income.

**27. Provision for mandatory dividends**

The Bank recognizes a liability (provision) for minimum or mandatory dividends based on the provisions of Article 79 of the Chilean Corporations Law, in line with the Bank's internal dividend policy, which stipulates that at least 30% of the net income for the year shall be distributed, unless a different agreement is reached at the respective Shareholders' Meeting by unanimous vote of the issued shares. As of May 2024, the Board of Directors agreed to exercise the authority granted by the most recent Ordinary Shareholders' Meeting to increase the provision for minimum dividends to 60% of accumulated earnings. In a regular Board meeting held in September 2024, it was agreed to further increase the provision for minimum dividends to 70%, following the same approach taken in the May 2024 Board meeting. For the year 2025, the percentage used for the provision for minimum dividends is 60%. This provision is recorded as a reduction of "Retained Earnings" under the item "Provision for dividends, interest payments, and revaluation of equity instruments" within the Interim Consolidated Statement of Change in Equity.

**NOTE 03 - NEW ACCOUNTING PRONOUNCEMENTS ISSUED AND ADOPTED OR ISSUED AND NOT YET ADOPTED**

**1. Pronouncements issued and adopted**

As of the date these Interim Consolidated Financial Statements were published, the new accounting pronouncements issued by both the FMC and the International Accounting Standards Board, which the Bank has fully adopted, are set out below:

***i.Accounting Standards issued by the Financial Markets Commission.***

**Circular No. 2,346 – Compendium of Accounting Standards for Banks. Chapters B-1 and E. Standardized provisioning model for consumer loans.** The regulation was issued on March 8, 2024, and establishes a new standardized methodology for calculating the minimum level of provisions, in which the PD (Probability of Default) is determined based on three factors: delinquency with the bank, delinquency within the financial system, and the holding of a residential mortgage loan. These factors allow for the timely recognition of risk and are aligned with the risk management practices carried out by financial institutions. Regarding the LGD (Loss Given Default), the model allows differentiation based on the type of loan (leasing or auto loans, installment loans, credit cards and lines of credit, or other consumer loans). It also distinguishes debtors who hold a residential mortgage loan within the financial system, enabling banks to recognize a loss level adjusted to the specific characteristics of each transaction. The regulation is effective as of 2025. As of the end of January 2025, the application of the new standardized consumer loan model resulted in an increase in provisions of Ch$93,901 million in the Consolidated Financial Statements, which includes Ch$16,057 million from the impact on the subsidiary Santander Consumer Finance Limitada.

**Guarantee Program and Interest-Rate Subsidy under Law No. 21,748**. Law No. 21,748 created a new guarantee program for new housing, as well as an interest-rate subsidy for mortgage loans, which consists of a reduction of up to sixty basis points (60 bps), provided that the loan is granted together with the guarantees supplied by the Special Guarantee Fund. This benefit applies exclusively to financing intended for the purchase of new housing, in first sale, with a value not exceeding 4,000 UF, and that meets the requirements established by the Ministry of Finance. The FMC, for its part, deemed it appropriate to clarify the accounting treatment, the estimate of provisions, the determination of the credit-risk weighting factor, the supervision of the Maximum Conventional Rate (TMC), the information regarding the implementation of the program to be submitted to the FMC, among other matters. The Bank is already offering this product in compliance with the established regulatory requirements.

***ii. Accounting Standards Issued by the International Accounting Standards Board.***

**Amendment to IAS 21 to clarify accounting treatment in the absence of convertibility**

The amendment, issued on August 15, 2023, provides guidelines on when a currency is considered exchangeable and how to determine the exchange rate when it is not. The amendments include:

&nbsp;&nbsp;&nbsp;&nbsp;i.Specifying when a currency is exchangeable for another currency and when it is not.

&nbsp;&nbsp;&nbsp;&nbsp;ii.Specifying how an entity determines the exchange rate to apply when a currency is not exchangeable.

&nbsp;&nbsp;&nbsp;&nbsp;iii.Requiring the disclosure of additional information when a currency is not exchangeable.

The amendment also includes a new appendix with application guidance on exchangeability and a new illustrative example. The amendments are applicable for annual periods beginning on or after January 1, 2025, with early application permitted. *The Bank has determined that there is no impact from this amendment.*

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 03 - NEW ACCOUNTING PRONOUNCEMENTS ISSUED AND ADOPTED OR ISSUED AND NOT YET ADOPTED, continued**

**2. Issued pronouncements which have not yet been adopted** 

As of the reporting date of these Interim Consolidated Financial Statements, new International Financial Reporting Standards had been published, as well as their interpretation and the FMC standards, which were not mandatory as of September 30, 2025. Accordingly, while the IASB permits an early application in some cases, the Bank has not undertaken its application by such date.

***i.Accounting Standards issued by the Financial Markets Commission*** 

**NCG No. 537 – Amends Chapter 8-41 of the Updated Compilation of Bank Regulations (UCBR) and Circular No. 1 for Non-Bank Card Issuers regarding the determination of a formula for calculating the minimum payment amount on credit cards, and the exceptional situations in which debtors will be released from this obligation.** On June 4, 2025, the FMC issued this amendment, aimed at including a formula for calculating the minimum payment amount on credit cards. NCG No. 537 amends Chapter 8-41 of the UCBR and Circular No. 1 for Non-Bank Issuers. The amendment to Chapter 8-41 of the UCBR includes a new section 5, "Special rules on credit cards", which establishes a formula and the variables to be considered in calculating the minimum amount that borrowers of money credit operations —originating from the use of credit cards through a revolving or consolidated credit line— must pay monthly to avoid delinquency. The minimum payment is the lowest amount the cardholder must pay each month to remain current. The mathematical formula consists of a percentage of the total billed amount, which requires defining the "non-financeable amount" (NFA) and the "financeable amount" (FM), where: Minimum Payment ≥ (100% × NFA) + (5% × FA)

This regulation came into force on June 4, 2025 with gradual application starting 12 months after its publication, following the mathematical expression for calculation set out in NCG No. 537. *The Bank is working on the implementation of this regulatory amendment.*

***ii.Accounting Standards issued by the International Accounting Standards Board.***

**IFRS 18 – Presentation and Disclosures in Financial Statements.** On April 9, 2024, the IASB issued IFRS 18, which replaces IAS 1: Presentation of Financial Statements. IFRS 18 introduces three sets of new requirements aimed at improving the information on financial performance and providing a better basis for analyzing and comparing companies:

• Improved comparability of the statement of profit or loss

• Greater transparency of management-defined performance measures

• More useful aggregation of information in the financial statements

IFRS 18 becomes effective for annual reporting periods beginning on or after January 1, 2027, with early application permitted. *The Bank is in the process of analyzing this standard.*

**IFRS 19 Non-Publicly Accountable Subsidiaries: Information to be disclosed. T**his regulation specifies the disclosure requirements that would apply to subsidiaries that are not obligated to publish financial accounts, but whose parent produces publicly available consolidated financial statements that comply with IFRS Standards.

On August 19, 2025, an amendment was issued allowing subsidiaries that do not have public accountability to apply IFRS standards with reduced disclosure requirements, waiving most of the disclosure obligations under other IFRS standards. These amendments enable eligible subsidiaries to reduce their disclosure requirements. This modification is aligned with the effective date.

With these updates, IFRS 19 is now aligned to cover information requirements through January 1, 2027, the date on which it will become fully effective.

This rule is applicable for periods beginning on or after January 1, 2027, with early application allowed. *The Bank is in the process of analyzing this regulation.*

**NOTE 03 - NEW ACCOUNTING PRONOUNCEMENTS ISSUED AND ADOPTED OR ISSUED AND NOT YET ADOPTED, continued**

**Amendment to IFRS9 and IFRS7 - amendment to the Classification and Measurement of Financial Instruments.** The modifications are:

*Amendments to IFRS 9 – Classification of Financial Assets:*

• Financial assets with ESG and similar features: Financial assets with contingent events may pass the SPPI Test if their cash flows are SPPI both before and after the contingent event, and the cash flows do not differ significantly from those of a similar asset without such a contingent event.

• Derecognition of financial liabilities settled through electronic transfer: An accounting policy option is allowed to derecognize such liabilities before the settlement date if certain conditions are met. If this option is chosen, it must be applied to all agreements settled through the same electronic payment system.

**Amendments to IFRS 7:**

• Investments in equity instruments designated at fair value through OCI: Entities must disclose the fair value result presented in OCI during the period, distinguishing the result from changes in fair value from the result due to derecognition.

• Contractual terms that may change the timing or amount of contractual cash flows: Disclosure is required for contractual terms that may modify the timing or amount of cash flows upon the occurrence (or non-occurrence) of a contingent event that is not directly related to changes in basic lending risks or costs. This applies to assets measured at amortized cost or fair value through OCI and to financial liabilities measured at amortized cost.

These amendments are effective for annual periods beginning on or after January 1, 2026. Early application is permitted. *The Bank is currently in the process of analyzing this standard.*

**Annual Improvements to IFRS – Volume 11.** This standard, issued on July 18, 2024, by the International Accounting Standards Board (IASB), addresses minor but necessary non-urgent amendments to the following five Standards:

IFRS 1 – First-time Adoption of International Financial Reporting Standards

IFRS 7 – Financial Instruments: Disclosures

IFRS 9 – Financial Instruments

IFRS 10 – Consolidated Financial Statements

IAS 7 – Statement of Cash Flows

The published amendments will be effective for annual periods beginning on or after January 1, 2026, with early application permitted. *The Bank is currently in the process of analyzing this standard.*

**IFRS 9 and IFRS 7 – Renewable Energy Power Purchase Agreements.** Issued on December 18, 2024, the amendments include:

• Amendments to IFRS 9 – Financial Instruments:

–The own-use requirements in IFRS 9 have been modified to include factors that an entity must consider when applying the scope of IFRS 9 (paragraph 2.4) to renewable energy power purchase agreements, for both the purchase and receipt of renewable electricity.

–The hedge accounting requirements have also been amended to allow an entity to use a renewable electricity contract as a hedging instrument by designating a variable volume of forecast electricity transactions as the hedged item, provided specified criteria are met, and measuring the hedged item using the same volume assumptions as those used for the hedging instrument.

• Amendments to IFRS 7 – Financial Instruments: Disclosures:

–Specific qualitative and quantitative disclosure requirements are introduced for electricity contracts, depending on their nature and specified characteristics.

The published amendments will be effective for annual reporting periods beginning on or after January 1, 2026, with early application permitted. *The Bank is currently in the process of analyzing this standard.*

In order to achieve the strategic objectives set by senior management and adapt to changing market conditions, the Bank periodically makes adjustments to its organizational structure. These modifications, in turn, have varying degrees of impact on how the Bank is managed and administered.

**Corporate activities ("Other")**

This segment includes Financial Management, which carries out global functions related to the management of structural currency positions, structural interest rate risk, and liquidity risk.

This segment also includes all intra-segment results and all activities not assigned to a specific segment or customer product.

The accounting policies for the segments are the same as those described in the summary of accounting principles and are tailored to meet the Bank's management needs. The Bank obtains the majority of its income from interest income, fee income, and results from financial operations. The chief decision-making authority of each segment relies primarily on interest income, fee income, and expense provisioning to evaluate segment performance and make decisions regarding the allocation of resources to each.

The Bank assessed those instruments with unrealized loss as of September 30, 2025 and concluded they were not impaired. This review assessed the economic drivers of any decline, the securities' issuer credit ratings and the Bank's intention and ability to hold the securities until the unrealized loss is recovered. Based on this analysis, the Bank considers there are no significant or prolonged declines or changes in credit risks to cause impairment in its investment portfolio. Most of these instruments' fair value decline was caused by market conditions that the Bank considers temporary. All instruments with unrealized loss as of September 30, 2025, were not in a continuous unrealized loss position for over one year.

The following table shows debt instruments and commercial and mortgage loans at fair value through other comprehensive income, including accumulated unrealized gains and losses as of September 30, 2025, and December 31, 2024:

**1. Micro-hedge accounting**

**Fair value micro-hedges**

The Bank uses cross-currency swaps, interest rate swaps, and call money swaps to cover its exposure to changes in the hedged item's fair value attributable to the interest rate. These hedging instruments change the effective cost of long-term issues from a fixed to a floating interest rate.

The following is a notional breakdown of hedged items and hedging instruments under fair value hedges, effective as of September 30, 2025, and December 31, 2024, separated by their term to maturity:

**Cash flow micro-hedging**

The Bank uses cross-currency swaps to hedge the risk of the variability of cash flows attributable to changes in the interest rate of bonds and interbank loans issued at floating rates and to hedge foreign currency fluctuations, mainly in US dollars. In addition, it uses both forward and cross-currency swaps to hedge the inflation risk on certain items.

The following are the notional amounts of the hedged item as of September 30, 2025, and December 31, 2024, and the period in which the flows will occur:

The valuation generated by those hedging instruments used in cash flow hedges whose effect was recorded in the Interim Consolidated Statement of Change in Equity, specifically within 'Other Accumulated Comprehensive Income', in cash flow hedges, is presented as follows:

---

| | | |
|:---|:---|:---|
| | As of September 30, As of December 31, | As of September 30, As of December 31, |
| **Hedged item** | 2025 | 2024 |

Considering that the variable flows of both the hedged item and the hedging instrument are mirrors of each other, the hedges are close to 100% efficient. This entails that all variations in value attributable to components of the hedged risk are almost fully netted. During the period, the Bank did not record any forecasted future transactions within its cash flow hedge accounting portfolio.

Furthermore, a provision is recorded for the difference between the higher initial award value plus any additions and its appraisal value.

***Share-based compensation (settled in cash)***

The Bank provides certain executives of the Bank and its affiliates a share-based payment benefit, which is settled in cash according to the requirements of IFRS 2. Accordingly, the Bank measures services received, and liabilities incurred at fair value.

Until settlement of the liability, the Bank determines the liability's fair value at the end of each reporting period and on the settlement date, with any fair value changes recognized in the period results.

***Pension plan***

The Bank has an additional benefit available to its senior executives, consisting of a pension plan with funds to provide for a better complementary pension upon retirement.

In this respect, the Bank will complement the voluntary contributions made by beneficiaries for their future pension with an equal contribution. Executives shall earn the right to receive this benefit only if they meet the following concurrent conditions:

&nbsp;&nbsp;&nbsp;&nbsp;a.Aimed at the Group's senior management.

&nbsp;&nbsp;&nbsp;&nbsp;b.The general requirement for eligibility is to be still employed when they are 60 years old.

&nbsp;&nbsp;&nbsp;&nbsp;c.The Bank will contract a mixed collective insurance policy (life and savings) for each executive, with the contracting party and beneficiary being the Group company to which the executive belongs.

In the event of termination of the employment relationship between the executive and the respective company before meeting the conditions described above, no entitlement shall accrue to them under this benefit plan.

Exceptionally, in the event of the manager's death or their total or partial disability, the manager or their heirs shall be entitled to receive this benefit as the case may be.

The Bank will contribute to this benefit plan based on mixed group insurance policies, the beneficiary of which is the Bank. The life insurance company with which these policies are contracted is unrelated to the Bank or any other Group company.

The Bank's entitlements under the plan as of September 30, 2025, and 2024 amounted to Ch$4,876 y Ch$5,582 million, respectively (Ch$4,107 millions as of December 31, 2024).

The Bank has quantified the amounts of the defined benefit obligations based on the following criteria:

***Calculation method:***

The projected unit credit method is used, which considers each year of service as generating an additional unit of benefit entitlement and values each unit separately. It is calculated according to the fund contribution that considers as the main parameters the factors related to the legal annual pension ceiling, the years of service, age and annual income of each unit valued individually.

***Actuarial assumptions used:***

Actuarial assumptions regarding demographic and financial variables are unbiased and mutually compatible. The most significant actuarial assumptions considered in the calculations were:

The assets related to the savings fund contributed by the Bank to Compañía de Seguros Zurich, for defined benefit plans, are presented net of the associated obligations. The assumptions used correspond to.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 43 - TRANSACTION WITH RELATED PARTIES**

The Bank's "related parties" include, in addition to its subsidiaries and associates, "key personnel" of the Bank's Management (members of the Bank's Board of Directors and Managers of Banco Santander-Chile and its affiliates, along with their close relatives), as well as entities over which key personnel may exercise significant influence or control.

Additionally, the Bank has considered the various companies that form part of the Santander Group worldwide as related parties, with the understanding that they all have a common parent company, namely Banco Santander S.A. (based in Spain).

Article 89 of the Chilean Corporation Law, which also applies to banks, establishes that any transaction with a related party must be carried out under fair conditions, similar to those normally prevailing in the market.

Furthermore, Article 84 of the General Banking Law establishes limits loans that may be granted to related parties and prohibits granting loans to the Bank's directors, general manager, or general representatives.

The Bank's transactions with its related parties are listed below. For ease of understanding, we have divided the information into four categories:

***Santander Group Companies***

This category includes all companies belonging to the Santander Group worldwide, and therefore also includes those companies over which the Bank exercises some degree of control (subsidiary and special-purpose entities).

***Associated Companies***

This category includes those entities where the Bank, as indicated in Note 01 b) of these Consolidated Financial Statements, exercises some degree of significant influence over them. These entities, in general, correspond to the so-called "business support companies."

***Key Personnel***

This category includes members of the Bank's Board of Directors and executives of Banco Santander-Chile and its affiliates, along with their close relatives. It takes into account the limitations imposed by Chapter 12-12 of the UCBR.

***Other***

This category includes related parties not included in the groups described above and, in general, those entities over which key personnel may exercise significant influence or control.

The terms of transactions with related parties are equivalent to those found in arm's-length transactions, or the corresponding in-kind compensation has been allocated.

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 44 - FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES**

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction in the principal (or most advantageous) market at the measurement date under current market conditions (i.e., an exit price), regardless of whether that price is directly observable or estimated using another valuation technique. Fair value measurement assumes that the sale of the asset or transfer of the liability occurs in the principal market for the asset or liability or in the most advantageous market for the asset or liability.

For financial instruments without available market prices, fair values have been estimated using recent transactions in similar instruments or, if not possible, current values or other valuation techniques based on mathematical valuation models sufficiently tested by the international financial community. When using these models, the specific characteristics of the asset or liability being valued are taken into account, and in particular, the different types of risks associated with the asset or liability.

These techniques are inherently subjective and significantly affected by the assumptions used, including the discount rate, estimates of future cash flows, and prepayment assumptions. Therefore, estimated fair value of an asset or liability not exactly matching the price at which the asset or liability could be delivered or settled at the valuation date and may not be justified by comparison with independent markets.

**Determination of the fair value of financial instruments**

The following table shows a comparison between the book value of the Bank's financial assets and liabilities and their corresponding fair values as of September 30, 2025, and December 31, 2024:

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 44 - FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES, continued**

Fair value approximates carrying amount in the following items, due to their short-term nature, in the case of: cash, bank deposits, and transactions in the process of settlement. Additionally, the fair value estimates presented above do not attempt to quantify the value of the Bank's earnings generated by its business or future activities, and therefore do not represent the value of the Bank as a going concern. Below is a description of the methods used to estimate the fair value of financial instruments.

**1. Debt financial instruments**

The estimated fair value of these financial instruments was established using market values or estimates from a readily available dealer or quoted market prices for similar financial instruments. The investments are valued at book (as recorded) value because they are not considered to have a fair value significantly different from their recorded value. Additional variables and elements (where applicable) were considered in estimating the fair value of debt investments, including estimates of prepayment rates and the issuers' credit risk.

**2. Loans and receivables from clients and Interbank loans**

The fair value of commercial loans, mortgage loans, credit cards, and consumer loans is measured using discounted cash flow analysis. For this purposes, prevailing market interest rates are used, taking into account the product, term, amount, and similar credit quality. The fair value of loans with a past due period of 90 days or more is measured using the market value of the associated collateral, discounted at the rate and expected maturity.&nbsp;&nbsp;&nbsp;&nbsp;

For variable-rate loans with frequently changing interest rates (monthly or quarterly) and not subject to significant credit risk, the estimated fair value is based on their carrying amount. The carrying amounts and fair values are presented net of provisions for credit risk.

**3. Deposit and other demand obligations**

The disclosed fair value of non-interest-bearing deposits and savings accounts is the amount payable at the reporting date and, therefore, equals the recorded amount. The fair value of time deposits is calculated using the discounted cash flow method, which applies current interest rates currently offered to a schedule of monthly maturities expected in the market.

**4. Short- and long-term debt instruments issued**

The fair value of these financial instruments is calculated using discounted cash flow analysis based on current incremental borrowing rates for similar types of loan agreements with similar maturities.

**5. Financial derivatives and accounting hedging contracts**

The estimated fair value of the foreign exchange forward contracts was calculated using quoted market prices for financial instruments with similar characteristics.

The fair value of interest rate swaps represents the estimated amount that the Bank determines as the exit price in accordance with IFRS 13. If there are no quoted market prices (direct or indirect) for any derivative instrument, the respective fair value estimates have been calculated using valuation models and techniques such as Black-Scholes, Hull and Monte Carlo simulations and considering relevant inputs such as option volatility, observable correlations between underlying assets, counterparty credit risk, implied price volatility, speed with which volatility reverts to its mean value, linear relationship (correlation) between the value of a variable.

**Fair value measurement and hierarchy**

IFRS 13, "Fair Value Measurement," establishes a fair value hierarchy that segregates the inputs and/or assumptions of valuation techniques used to measure the fair value of financial instruments. The hierarchy gives highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and lowest priority to measurements that involve significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 44 - FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES, continued**

• Level 1: Inputs are quoted (unadjusted) prices in active markets for identical assets and liabilities for which the Bank has access at the measurement date.

• Level 2: Inputs other than quoted prices included in Level 1 that are observable for assets or liabilities, directly or indirectly.

• Level 3: Unobservable inputs for the asset or liability.

The estimated fair value of the foreign exchange forward contracts was calculated using quoted market prices for financial instruments with similar characteristics.

The fair value of interest rate swaps represents the estimated amount the Bank expects to receive or pay to terminate the contracts or agreements, taking into account the term structures of the interest rate curve, volatility of the underlying asset, and the credit risk of the counterparties.

In cases where quotations cannot be observed, management makes its best estimate of the market price using its own internal models, which, in most cases, use data based on observable market parameters as significant inputs (Level 2) and, in limited cases, use significant inputs that are not observable in market data (Level 3). Various techniques are used to arrive at this estimate, including extrapolation of observable market data.

Financial instruments at fair value and determined by published quotes in active markets (Level 1) include:

• Instruments of the Chilean Central Bank and the General Treasury of the Republic.

• Foreign instruments issued.

• Mutual funds.

If the instruments are not 100% market-observable, however, the price is a function of other prices that are market-observable (Level 2). The following financial instruments are classified as Level 2:

---

|:---|:---|:---|
| **Type of financial <br>instrument** | **Valuation model used** | **Description** |
| Private bonds  | Present value of cash flows | Internal Rates of Return ("IRRs") are provided by independent pricing source service entity, according to the following criteria:<br>On the valuation day, if there are one or more valid transactions in the Santiago Stock Exchange for a given mnemonic code, the reported rate is the weighted average of said rates.<br>If there are no valid transactions for a given mnemonic data on the valuation day, the reported rate is an 'IRR baseline' from a reference structure plus a 'Model Spread' based on information from historical spreads of the same or similar documents. |
| Time deposits | Present value of cash flows | Internal Rates of Return ("IRRs") are provided by independent pricing source service entity, according to the following criteria:<br>On the valuation day, if there are one or more valid transactions in the Santiago Stock Exchange for a given mnemonic code, the reported rate is the weighted average of said rates.<br>If there are no valid transactions for a given mnemonic code on the valuation day, the reported rate is an 'IRR baseline' from a reference structure plus a 'Model Spread' based on the 'Issuer curves'. |
| Constant Maturity Swap (CMS), Forward FX and Inflation, Cross Currency Swap (CCS), Interest Rate Swap (IRS) | Present value of cash flows | Rates (IRR) are provided by ICAP, GFI, Tradition and Bloomberg according to the following criteria:<br>The published market prices are used to construct the valuation curve using the bootstrapping method, and then this curve is used to value the various derivatives. |
| FX Options | Black-Scholes | Formula adjusted by the volatility smile (implied volatility). BGC Partners provide prices (volatilities) according to the following criteria: <br>The volatility surface is built through interpolation using published market prices, and these volatilizes are then used to value the options. |
| Guarantees for threshold transactions, guarantee deposits | Present value of cash flows | Transactions related to derivatives contracts such as Constant Maturity Swap (CMS), Forward FX and Inflation, Cross Currency Swap (CCS), Interest Rate Swap (IRS) and FX Options. |

In limited cases, unobservable inputs are used in market data (Level 3). Various techniques are used to perform this estimation, including extrapolation of observable market data or a mix of observable data.

The following financial instruments are classified as Level 3:

---

| | | |
|:---|:---|:---|
| **Type of financial<br> instrument** | **Valuation<br> model used** | **Description** |
| Caps/Floors/Swaptions  | Black Normal model for Cap/Floors and Swaptions | There is no observable input of implied volatility. |
|  | Black-Scholes | There is no observable input of implied volatility. |
|  | Hull-White | Hybrid HW model for rates and Brownian motion for FX. There is no observable input of implied volatility. |
|  | Implicit Forward Rate Agreement (FRA) | Start Fwd is unsupported by Murex (platform) due to the UF forward estimate. |
| CCS, IRS, CMS in Active Bank Rate (TAB) | Present value of cash flows | Valuation obtained using yield curve interpolating to maturity of flows. Nevertheless, TAB is not a directly observable variable nor correlated to any market input. |
|  | Present value of cash flows | Valuation using prices of instruments with similar characteristics plus a liquidity charge-off rate. |
| CCS (maturities over 30 years) | Present value of cash flows | Rates (IRR) are provided by ICAP, GFI, Tradition and Bloomberg according to the following criteria:<br>The published market prices are used to construct the valuation curve using the bootstrapping method and then this curve is used to value the various derivatives. |
| Receivables accounts valued at fair value | Present value of cash flows | Measured by discounting the estimated cash flow using the interest rate of the new contracts. |
| Mortgage bonds | Present value of cash flows | The rates (IRR) are provided by RiskAmérica according to the following criteria: If on the valuation date there is one or more valid transactions on the Santiago Stock Exchange for a specific security code, the reported rate is the weighted average (by amount) of the observed rates. If there are no valid transactions for a given security code on the valuation date, the reported rate is a "base IRR" derived from a reference curve, plus a "Model Spread" based on historical spread data for the same instrument or similar ones. |

The Bank estimates that any changes in unobservable criteria for instruments classified at Level 3 would not result in significant differences in the fair value measurement.

The fair value of other assets and liabilities approximates their carrying amounts.

The methods and assumptions for estimating fair value are defined below:

• Loans and amounts owed by credit institutions and customers: Fair value is estimated for groups of loans with similar characteristics. Fair value was measured by discounting the estimated cash flow using the new contract interest rate. First, the future cash flow of the current loan portfolio is estimated using contractual rates, and then the new loans distributed at the risk-free interest rate are incorporated into the (risk-free) yield curve to calculate the loan portfolio at fair value.

Regarding behavioral assumptions, it is important to emphasize that a prepayment rate is applied to the loan portfolio, thus providing a more realistic future cash flow:

• Deposits and liabilities with banks: The fair value of deposits was calculated by discounting the difference between cash flows on a contractual basis and current market rates for instruments with similar maturities. For variable-rate deposits, the carrying amount was considered to approximate fair value.

• Debt instruments issued and other financial obligations: The fair value of long-term loans was estimated using discounted cash flows at the market interest rate with similar terms and maturities.

The valuation techniques used to estimate each level are defined in Note 2.

The following table presents the Bank's activity for assets and liabilities measured at fair value on a recurring basis using significant unobserved inputs (Level 3) as of September 30, 2025, and December 31, 2024:

The internal Local Risk Factor Committee, which meets quarterly, reviews the cases in which transfers between different levels are required. During 2025, the Bank did not reclassify instruments from Level 3 to Level 2.

Realized and unrealized gains (losses) included in income as of September 30, 2025, and December 31, 2024 arising from assets and liabilities measured at fair value on a recurring basis through significant unobservable inputs (Level 3), are recorded in the Interim Consolidated Statements of Income under the caption "Net income from financial operations."

The potential effect as of September 30, 2025, and December 31, 2024, on the valuation of assets and liabilities measured at fair value on a recurring basis through significant unobservable inputs (Level 3) that would result from a change in the main assumptions in the case of using other reasonably possible assumptions less or more favorable than those used, is not considered significant for the Bank.

In order to reduce credit exposure in its financial derivatives transactions, the Bank has entered into bilateral collateral agreements with its counterparties, which establish the terms and conditions under which these transactions operate. In generally, collateral (received/delivered) is issued when the net fair value of the financial instruments held exceeds the thresholds defined in the respective contracts.

The financial derivative contracts are detailed according to their collateral agreement:

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 47 - RISK MANAGEMENT AND REPORTING** 

***General information***

For Banco Santander, risk management is the core of its business. The Bank's corporate governance continually optimizes its risk management and control system, based on the Basel Committee's principles, an integrated risk culture, a robust governance structure, and advanced tools, with the goal of ensuring responsible conduct in response to economic changes, customer demands, and legal regulations. The Board of Directors assumes ultimate responsibility in this area, including the approval of risk appetite, the regulatory framework, and the promotion of a consistent organizational culture.

The Bank's risk management and control are based on the following principles, that consider both regulatory requirements and market best practices and must be applied at all times:

1. All employees are responsible for risk management and must know and understand the risks generated by their daily activities, avoiding taking risks whose impact is unknown or exceeding the limits of the Bank's risk appetite.

2. Senior management is involved, ensuring consistent risk management and control through its conduct, actions, and communications. Additionally, it will promote the risk culture, assessing its degree of implementation and ensuring that the profile remains within the levels defined in the Bank's risk appetite.

3. Independence of risk management and control functions.

4. An anticipatory and comprehensive approach to risk management and control across all businesses and types of risks.

5. Correct and complete information management that allows risks to be identified, evaluated, managed and communicated appropriately to the corresponding levels

These principles, along with a series of interrelated tools and processes in its strategy, such as risk appetite, risk profile assessment, scenario analysis, and risk reporting framework, as well as annual budgeting processes, constitute a holistic control structure for the entire Bank.

The Bank's risk classification enables effective risk management, control, and communication. Its corporate risk framework includes the following:

• Credit risk: It is the risk of financial loss resulting from the default or deterioration of the credit quality of a client or counterparty for whom Banco Santander Chile has financed or with whom it has assumed a contractual obligation.

• Market risks: These arise from holding financial instruments whose value may be affected by changes in market conditions; they generally include the following types of risk:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Foreign exchange risk: which arises as a result of fluctuations in the exchange rate between currencies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fair value risk due to interest rate fluctuations: which arises as a result of fluctuations in market interest rates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Price risk: which arises as a result of changes in market prices, either due to factors specific to the instrument itself or due to factors that affect all instruments traded in the market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inflation risk: which arises as a result of changes in inflation rates in Chile, the effect of which would apply primarily to financial instruments denominated in UF.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• Liquidity risk: It is the risk of not having the necessary liquid financial resources to meet obligations when they mature, or of obtaining them only at a high cost.

• Operational risk: It is the risk of loss due to inadequate or failed internal processes, employees, and systems, or due to external events. This includes legal risk and conduct risk.

• Capital risk: It is the risk that the Bank has insufficient capital in quantity and/or quality to meet the minimum requirements for operating as a bank, meeting market expectations regarding its creditworthiness, and supporting the growth of its business and any strategies that may arise in accordance with its strategic plan.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

**Risk governance**

The Bank has a robust risk governance structure that pursues effective risk profile control, in accordance with the appetite defined by the Board of Directors and based on the distribution of roles among the three lines of defense and a solid committee structure. The Bank's three lines of defense model seeks to ensure effective risk management and control:

First line: business lines and all other risk-generating functions constitute the first line of defense. These functions must ensure that the risks generated are aligned with the approved risk appetite and corresponding limits. Any unit that generates risk has primary responsibility for managing that risk.

Second Line: the risks, compliance, and conduct functions. Their role is to independently oversee and challenge the risk management activities performed by the first line of defense. These functions ensure risk management in accordance with the appetite defined by the Board and promote a strong risk culture throughout the organization.

Third Line: the Internal Audit function periodically assesses the appropriateness and effectiveness of policies, methodologies, and procedures for managing and controlling all risks. The risk, compliance, and internal audit functions enjoy an appropriate level of separation and independence and have direct access to the Board of Directors and its committees.

The governance applied in the Bank must promote efficient governance structures that ensure the participation of all relevant functions. Governance must also be compatible with local-level functions and with coordinated management and supervision.

The main objectives of risk governance are:

→ Enable effective and efficient risk decision-making.

→ Oversee risk control.

→ Ensure that risks are managed in accordance with the risk appetite defined by the Board.

The governance structure must separate risk management and control, to achieve these objectives:

→ Governance reinforces the responsibility of the first line of defense in decision-making and ensures that all risk decisions have a formal approval process.

→ For the second line of defense, governance provides an overview of all risks, regardless of who manages or controls them.

**Risk government structure**&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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

The risk governance structure meets legal and regulatory requirements, which is characterized by an efficient governance structure that ensures the participation of all relevant areas, promoting clear and effective decision-making and accountability.

The responsibilities and membership of the most relevant committees within risk governance are:

&nbsp;&nbsp;&nbsp;&nbsp;1.Board of Directors: ultimately responsible for risk management and control. Its key responsibilities include approving the risk appetite and risk framework, and promoting a strong risk culture. To support the Board's management, there are five committees, which are established and amended according to the bank's needs. These committees report their activities to the Board periodically through meetings and subrogation schemes, statutes, formal minutes, and monitoring processes: the Directors and Audit Committee, the ALCO and Markets Committee, the Integral Risk Committee, the Appointments Committee, and the Compensation Committee.

&nbsp;&nbsp;&nbsp;&nbsp;2.Integral Risk Committee (IRC): is responsible for advising the Board of Directors on defining the risk appetite that business areas can assume, as well as overseeing the correct identification, measurement, and control of all risks that may affect the Bank.

&nbsp;&nbsp;&nbsp;&nbsp;3.Executive Risk Committee: responsible for risk management, in accordance with the powers delegated to it. This committee evaluates credit operations over a certain amount (operations of smaller amounts are evaluated by lower-level committees).

&nbsp;&nbsp;&nbsp;&nbsp;4.Risk Control Committee: responsible for risk control, determining whether businesses are managed in accordance with the risk appetite and providing a holistic view of all risks. This includes identifying and monitoring both current and emerging risks and their impact on the risk profile.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

&nbsp;&nbsp;&nbsp;&nbsp;5.Global Compliance Committee: responsible for overseeing the management of the risks to which the Bank is exposed, including regulatory compliance risk, conduct risk, money laundering and terrorist financing risk, and reputational risk.

&nbsp;&nbsp;&nbsp;&nbsp;6.Analysis and Resolution Committee (CAR): responsible for defining and monitoring compliance with the policies, standards, and general and specific objectives regarding the prevention of money laundering and terrorist financing, in accordance with local laws and regulations, as well as those of the Santander Group

**Risk assessment and identification**

The Bank evaluates at least once a year all the types of risk to which it is exposed, allowing it to define the level to which it is exposed in each of them through a systematic and objective process.

Also, through a formal process, it reviews the evolution of each risk by analyzing qualitative and quantitative variables. The results are presented and discussed monthly at the highest management and supervisory levels.

In parallel, emerging risks are surveyed every six months, a process in which a large part of the organization participates. This process identifies the main potential risks that could jeopardize strategic planning from a holistic perspective, allowing for a prioritization of these risks based on an assessment of their impact on results/capital and the probability of occurrence. It is important to highlight that this process allows new concerns to be identified and made visible in order to contain them.

**Key Risk Management and Control Processes**

It is important to note that each of these key processes has demanding standards, which reflect international best practices.

→ Planning. Planning is the process by which business objectives are established. It must include the formulation of the types and levels of risk that the business is able and willing to assume to achieve those objectives.

→ Identification. Risk identification is an essential component for effective risk management and control. All employees are responsible for identifying the risks within their scope of work.

→ Assessment. Once identified, risks must be assessed.

→ Decision-making and execution. Decisions are necessary to manage the business risk profile within the limits approved in the planning phase and to achieve business objectives. Strategic decisions are also necessary to manage material and emerging risks.

→ Monitoring plan performance. Regular monitoring of business performance and comparing it with approved plans is an essential daily activity.

→ Measures to correct deviations from the plan and information processes If the monitoring activity reveals deviations, or probable deviations, from performance beyond the approved ranges or alert levels, mitigation measures should be considered to return performance to acceptable levels.

**CREDIT RISK**

Credit risk is the risk of financial loss resulting from the default or deterioration of the credit quality of a client or counterparty for whom the Bank has financed or with whom it has assumed a contractual obligation. It is our most significant risk, both in terms of exposure and capital consumption.

***Credit risk management***&nbsp;&nbsp;&nbsp;&nbsp;

The Bank's credit risk identification, analysis, decision-making, and control processes are based on a complete view of the credit risk cycle, including the transaction, the client, and the portfolio. Credit risk identification enables active management and effective portfolio control. We identify and classify external and internal risks in each business and adopt corrective and mitigating measures when necessary, through the following processes:

1. Planning: Planning allows us to establish business objectives and define specific action plans in line with our risk appetite statement. Commercial strategic plans are a management and control tool defined by the business and risk areas for our credit portfolios. They determine commercial strategies, risk policies, resources, and infrastructure, ensuring a holistic view of the portfolios.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

2. Risk Assessment and Credit Rating Process: Credit approval criteria are generally based on a borrower's ability to meet his or her financial obligations. To determine this ability, we analyze the borrower's net cash flow or business income. Our credit quality assessment models are based on rating engines, which vary for each of our segments, which we monitor and compare to adjust the decisions and ratings we assign.

3. Scenario analysis: This allows for determining potential risks in credit portfolios, providing a better understanding of their behavior under different macroeconomic conditions, as well as anticipating and implementing management strategies to avoid future deviations from established plans and objectives.

4. Monitoring: Holistic monitoring of all clients facilitates monitoring of credit quality and early detection of impacts on risk evolution. Regular monitoring of business performance and its comparison with pre-established plans are essential in credit risk management. Our monitoring function uses a system that helps establish monitoring levels, policies, and specific actions for each client.

5. Credit risk mitigation techniques: Credit approval criteria are based on determining the borrowers' ability to pay to meet their financial obligations, without relying on guarantors or pledged assets as collateral. These are always considered a second source of recovery in the event of the failure of the first, and are defined as a reinforcing measure added to a credit transaction in order to mitigate the loss in the event of default.

6. Recovery management: Recovery management defines a strategy based on the economic environment, business model, and other specificities of local recovery. Effective and efficient recovery management requires segmenting our clients based on their characteristics and using new digital channels that support sustainable value creation.

The Board of Directors has delegated responsibility for credit risk management to the IRC and the Bank's risk departments, whose roles are summarized below:

• Formulation of credit policies, in consultation with the business units, covering collateral requirements, credit evaluation, risk rating, and reporting, documentation, and legal procedures in compliance with the Bank's regulatory, legal, and internal requirements.

• Establishing the authorization structure for the approval and renewal of credit applications. The Bank structures credit risk levels by placing limits on the concentration of that risk in terms of individual debtors, debtor groups, industry segments, and countries.

• Authorizations are assigned to the respective business unit officers (commercial, consumer, SME) for ongoing monitoring by Management. These limits are also reviewed periodically. Branch-level risk assessment teams regularly interact with clients; however, for large transactions, the parent company's risk teams, including the CIR, work directly with clients to assess credit risks and prepare credit applications.

• Limit exposure concentrations to clients and counterparties, by geographic area, industry (for receivables or loans), and by issuer, credit rating, and liquidity (for investments).

• Develop and maintain the Bank's risk classification, classifying risks according to the degree of exposure to financial loss faced by the respective financial instruments and focusing risk management specifically on the associated risks.

• Review and assess credit risk. The risk divisions are largely independent of the Bank's commercial division and assess all credit risks in excess of designated limits prior to approving loans to clients or prior to the acquisition of specific investments. Credit renewals and reviews are subject to similar processes.

Risk assessment teams interact regularly with our clients. For larger transactions, risk teams work directly with clients to assess credit risks and prepare credit applications.

Credit approval committees, which include risk and commercial staff, must ensure that each applicant meets the appropriate qualitative and quantitative parameters. The powers of each committee are defined by the Bank's Board of Directors.

When preparing a credit application for a corporate client whose loans are approved on an individual basis, the Bank verifies several parameters such as debt service capacity (usually including projected cash flows), the client's financial history, and/or projections for the economic sector in which it operates. The risk division is closely involved in this process and prepares the client's credit application. All applications contain an analysis of the client's strengths and weaknesses, a rating, and a recommendation. Credit limits are not determined based on the client's outstanding balances, but rather on the direct and indirect credit risk of the financial group. For example, a corporation would be assessed along with its subsidiaries and affiliates.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

Consumer loans are evaluated and approved by their respective risk divisions (individuals, SMEs). The evaluation process is based on an evaluation system known as Garra (Banco Santander-Chile), an automated process based on a scoring system that includes the credit risk policies implemented by the Bank's Board of Directors. The loan application process is based on the collection of information to determine the client's financial situation and repayment capacity. The parameters used to evaluate the applicant's credit risk include several variables such as income level, length of current employment, debt indebtedness, and credit agency reports.

In the case of investments in debt instruments, the Bank assesses the probability of default of the issuers or counterparties using internal and external assessments, such as those by risk assessors independent of the Bank. Furthermore, the Bank adheres to a strict and conservative policy that ensures that the issuers of its investments and counterparties in derivative transactions are of the highest reputation.

Additionally, the Bank operates with several instruments that involve exposure to credit risk, which are not reflected in the Interim Consolidated Statements of Financial Position, such as, for example: guarantees and warranties, documentary letters of credit, guarantee notes and commitments to grant credits..

Guarantees and warranties represent an irrevocable payment obligation. If a guaranteed client fails to meet their obligations to third parties guaranteed by the Bank, the Bank will make the corresponding payments. Therefore, these transactions represent the same credit risk exposure as a regular loan.

Documentary letters of credit are commitments documented by the Bank on behalf of the client. These commitments are secured by the traded goods they relate to and have a lower risk than direct borrowing. Guarantee bonds are contingent commitments that become effective only if the client fails to perform the work agreed upon with a third party, guaranteed by them.&nbsp;&nbsp;&nbsp;&nbsp;

When it comes to credit commitments, the Bank is potentially exposed to losses equal to the total undrawn commitment. However, the probable loss is less than the total undrawn commitment. The Bank monitors the maturity period of credit lines because long-term commitments generally carry a higher credit risk than short-term commitments.

**Additional provisions**

Under FMC regulations, banks are allowed to establish provisions above the limits described above, in order to protect themselves from the risk of unpredictable economic fluctuations that could affect the macroeconomic environment or the situation of a specific economic sector. These provisions, in accordance with Chapter B-1, Section 9 of the FMC's CASB, will be reported as liabilities.

The Bank's Board of Directors approved the constitution of additional voluntary provisions, which amount to Ch$179,098 million as of September 30, 2025, and December 31, 2024.

**Maximum exposure to credit risk**

For financial assets recognized in the Interim Consolidated Statements of Financial Position, the credit risk exposure is equal to their carrying amount. For financial guarantees granted, the maximum credit risk exposure is the maximum amount the Bank would have to pay if the guarantee were enforced.

According to the CASB, provisions for interbank loan,s and Loans and receivables from customers, and contingent operations are determined according to the criteria defined in chapters B-1 to B-3 of the CASB. Meanwhile, Loans and receivables from customers and debt instruments measured at fair value through other comprehensive income, and debt instruments measured at amortized cost, their impairment is measured in accordance with Chapter 5.5 of IFRS 9. Impairment requirements do not apply to debt instruments measured at fair value through profit or loss. In the case of derivatives, the adjustment that reflects the counterparty credit risk (CVA) is included in their fair value. CVA is calculated considering the potential exposure to each counterparty in future periods.

The methodology established for determining provisions for loans (Interbank and Loans and receivables from customers) and contingent loans is set out in Note 2 of accounting principles, letter q). The methodology used to calculate provisions for Loans and accounts receivable from customers and debt instruments measured at fair value through other comprehensive income, and debt instruments measured at amortized cost, is described in Note 2, letter r). Information related to the concentration of credit risk is provided in Note 13, letters k, m and n.

For derivative instruments, as of September 30, 2025, the Bank's foreign exposure, including counterparty risk in the derivatives portfolio, was MMUS$1,975.12, or 3% of assets. The exposure to equivalent credit risk for derivative instruments, which is calculated as the net replacement value plus the maximum potential value, considering cash collateral, which mitigates the exposure, for our exposure to those countries rated above 1, is as follows:

**Recognition and measurement of credit risk provisions**

The Bank segments loans and contingent loans by borrower type and loan type, to a level appropriate for the application of the models.

The provisions required to cover loans, debt instruments, and contingent loan exposure are calculated and recorded monthly, based on the valuation models used and the type of transaction.

Provisions related to loans and receivables from customers/debt instruments measured at amortized cost and loans and receivables from customers at fair value through other comprehensive income are accounted as valuation accounts into respective items, and reporting net in the Consolidated Statement of Financial Position. Additional provisions and contingent loans provisions are reported as liabilities, in accordance with the FMC's directions.

Provisions for financial assets at fair value through other comprehensive income are presented in Note No. 11, provisions for financial assets at amortized cost are presented in Note No. 13, and special provisions for credit risk (contingent loans, country risk, additional provisions) are presented in Note No. 26.

Below is a summary of the financial assets and contingent loan exposure, subject to credit risk, and their respective provisions according to CASB standards (B1 to B3) as of September 30, 2025 and December 31, 2024:

| Loans and receivables at fair value with changes in other comprehensive income | 668 | 1141 |
| **Total** | **2560** | **2678** |

---

As of September 30, 2025 and December 31, 2024, the debt instrument portfolios include mainly instruments from the Chilean Central Bank and the General Treasury of the Republic, whose risk has been classified as low (without a significant increase in credit risk). A description of the IFRS 9 model applied to determine these provisions is found in Note 2, letter r). As of September 30, 2025 and December 31, 2024, the loans and receivables measured at fair value through other comprehensive income are high credit quality assets with assessed individually.

 ***Defaulted loans***

The defaulted loan portfolio includes debtors and their loans whose recovery is considered remote, as they show a deteriorated or non-existent payment capacity, have been subject to forced restructuring or are overdue by 90 days or more in the payment of interest or principal, and are classified as non-performing (C1 to C6).

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

***Individual/Group***

Group assessments are suitable for addressing a large number of transactions with low individual amounts, involving individuals or small businesses. The Bank groups borrowers with similar credit risk characteristics, assigning each group a specific probability of default and a recovery percentage based on a substantiated historical analysis. For this purposes, the Bank implemented the standard model for housing and commercial loans, and an internal model for consumer loans.

IFRS 9 establishes the recognition of lifetime expected credit losses when significant increases in credit risk are observed since initial recognition. In that context, a collective assessment may be required, as the increase in credit risk may become more evident before the financial assets becomes nonperforming, depending on the nature and information available for the financial assets. This is always based on the assumption that the information is available without cost or effort.

***Impaired loans***

The impaired loan portfolio includes defaulted loans (C1 to C6), plus loans B3 and B4, in the case of individual assessments. As of September 30, 2025 and December 31, 2024, the impaired loan portfolio amounts to Ch$2,813,387 million and Ch$2,523,808 million, respectively.

IFRS 9 defines an asset as credit-impaired when one or more events have occurred that have a negative impact on estimated future cash flows, evidenced by the issuer's financial difficulties, default, bankruptcy or financial reorganization, disappearance from an active market, among others. Debt instruments and loans and receivables from customers measured at fair value through other comprehensive income are not credit impaired.

***Write-off***

Write-offs must be made when contractual rights to cash flows expire. A write-off constitutes a derecognition event from balance sheet and include the unpaid portion in the case of installment loans (no partial write-off). Additional circumstances could lead the write-off of a loan: when the Bank concludes that it will not obtain any cash flows, or there is no enforceable title, when the collection demand actions expire, or when the deadlines defined by the FMC are reached (see Note 2, letter q). As of September 30, 2025 and December 31, 2024, the written-off loans amounted to Ch$555,890 million and Ch$302,814,814 million, respectively.

IFRS 9 establishes that a write-off occurs when there is no reasonable expectation of recovering the contractual cash flows in whole or in part. A write-off constitutes a derecognition. Debt instruments and loans and receivables from customers measured at fair value through other comprehensive income do not include any written-off instruments/transactions.

***Reconciliation of provisions and loans***

The reconciliation between the opening and closing balances of provisions for financial assets measured at amortized cost and for contingent loans are presented in Note 13 letters f, g, h, i and j. The reconciliation between the opening and closing balances of provisions for financial assets measured at fair value with changes in other comprehensive income is presented in Note No. 11. The reconciliation of Interbank loans, commercial loans, mortgage loans, consumer loans, and exposure to contingent loans as of September 30, 2025, and December 31, 2024 is presented below:

The normal portfolio encompass debtors whose payment capacity allows them to meet their obligations and commitments, and this is not expected to change. When a debtor experiences financial difficulties or a significant deterioration in its payment capacity, and there are reasonable doubts about the full recovery of principal and interest under the contractual terms, the client is classified in the substandard portfolio. A client will be classified in the defaulted portfolio if the probability of credit recovery is considered remote, as it payment capacity is deteriorated or nonexistent.

**Guarantees and credit enhancements**

Maximum exposure to credit risk is, in some cases, reduced by collateral, credit enhancements, and other actions that mitigate the Bank's exposure. Based on this, guarantees are a necessary but insufficient instrument in granting loans; therefore, the Bank's risk acceptance requires verification of other variables or parameters, such the payment capacity or generation of resources to mitigate the risk incurred.

The procedures for management and valuation of guarantees are included in the internal risk management policy. These policies establish the basic principles for credit risk management, and the management over guarantees received in operations with clients. In this regard, the risk management model includes assessing the existence of appropriate and sufficient guarantees that allow credit recovery when the debtor's circumstances prevent him from meeting his obligations.

The collateral valuation procedures are consistent with market best practices, which involve the use of appraisals for real estate guarantees, market value for stock market securities, the value of investment fund shares, etc. All received guarantees must be properly instrumented and appropriately registered, as well as have the approval of the Bank's legal divisions.

The Bank also has rating tools that allow ranking the credit quality of transactions or clients. The Bank historical databases, store internally generated information, that allow to study the probability of variation. Rating tools consider client segment analyzed (commercial, consumer, SME, etc.).

The maximum exposure to credit risk by type of loans, the associated collateral and the net exposure to credit risk as of September 30, 2025, and December 31, 2024 are presented below:

Mortgage loans, by their nature, are secured by the property underlying the transaction, meaning that the property acquired by the customer guarantees the loan. When the Bank is required to take possession of or foreclose on a property, it is recorded as an "Asset received or awarded in lieu of payment," and the loan and its allowance are derecognized. The asset received is recorded at the lower of its carrying amount and its fair value (appraisal) less costs to sell, in accordance with IFRS 5, and is classified as held for sale. Once a loan has been derecognized, there are no further collection or enforcement activities.

The following are the impaired and non-impaired financial assets that have associated guarantees, collateral or credit enhancements in favor of the Bank as of September 30, 2025, and December 31, 2024:

Financial derivative transactions are guaranteed by collateral agreements, which are deposited or transferred by one third party on behalf of another. These can be in cash or financial instruments, and reduce the counterparty's credit risk. These guarantees are monitored periodically (usually daily). Based on this, the net balance per counterparty is determined, and based on agreed-upon parameters, it is determined whether a collateral should be deposited or collected.

**Credit limits for borrowers related to the Bank's ownership or management**

In accordance with Article 84 No. 2 of the General Banking Law and UCBR 12-4, the total amount of credit granted to a group of related parties may not exceed 5% of the Bank's regulatory capital. This limit increases to 25 percent if the portion exceeding 5 percent consists of loans secured by collateral. In no case may the total of such credits granted by a bank exceed the amount of its regulatory capital. These loans may not be granted under more favorable conditions in terms of maturity, interest rates, or collateral than those offered to third parties in similar transactions.

A relationship with the Bank occurs when they have a direct, indirect, or third-party participation in the Bank's ownership, participate in the management, or are presumed to exist until sufficient evidence is presented to eliminate that presumption.

It will be understood that all natural and legal persons who can exert significant and permanent influence on the decisions of the other form the same group of persons related to the Bank, where there is a presumption that the credits granted to one person will be used for the benefit of another or a well-founded presumption that the persons maintain a relationship and form a unit of economic interest.

Companies related to a Bank include subsidiaries, support companies, and affiliates.

Legal guarantees include guarantees on tangible personal or real property, real estate, or any other property that can legitimately be accepted as collateral.

On September 30, 2025, and December 31, 2024, the credit limit for debtors related to the ownership or management of the Bank according to article 84 No. 2 of the GBL and Chapter 12-4 of the UCBR are as follows:

**MARKET RISK**

Market risk arises as a result of market activity involving financial instruments whose value may be affected by fluctuations in market conditions and reflected in assets/liabilities changes and financial risk factors. The objective of market risk management is to manage and control exposure to market risk within acceptable parameters. There are four major risk factors that affect market prices: interest rates, exchange rates, price, and inflation.

\*Interest Rate Risk: the exposure to losses arising from adverse changes in market interest rates that affect the value of instruments, contracts and other transactions recorded on the balance sheet.

\*Exchange risk is the sensitivity to losses arising from adverse changes in the value of the exchange rates of foreign currencies, including gold, in which the instruments, contracts and other transactions recorded on the balance sheet are denominated.

\*Inflation risk is the exposure to losses arising from adverse changes in the units or indices of readjustment defined in national currency. The instruments, contracts, and other transactions are denominated on the balance sheet.

\*Price risk is generated by the volatility of rates or prices of assets or liabilities. Prepayment risk arises when, based on price movements, holders can alter the future cash flows of these assets or liabilities, leading to balance sheet mismatches that pose additional challenges to market risk management.

***Market risk management***

The measurement and control of market risks are the responsibility of Market Risk Area, which is part of the Risk Division. The appropriate committees approve the limits, with responsibility resting mainly with the ALCO. The Integral Risk Committee also reviews the principal market risks. The Financial and Capital Management areas, as part of the Financial Vice-Presidency, have the following functions, which are supervised and controlled by the ALCO and Risk Division:

&nbsp;&nbsp;&nbsp;&nbsp;i.To optimize the cost of liabilities and seek the most efficient financing strategies, including issuing bonds and bank facilities.

&nbsp;&nbsp;&nbsp;&nbsp;ii.Management of short- and long-term regulatory liquidity limits.

&nbsp;&nbsp;&nbsp;&nbsp;iii.Inflation risk management and exposure.

&nbsp;&nbsp;&nbsp;&nbsp;iv.To manage local and foreign currency rate risk.

&nbsp;&nbsp;&nbsp;&nbsp;v.Capital adequacy and requirements.

Rate sensitivity is measured primarily using an analysis that quantifies the impact on earnings and the balance sheet of parallel movements in the real and nominal interest rate curve in Pesos and US dollars.

The Bank's internal management for measuring market risk is mainly based on analyzing the management of the following three components:

• Trading portfolio.&nbsp;&nbsp;&nbsp;&nbsp;

• Local currency financial management portfolio.

• Foreign currency financial management portfolio.

The Treasury manages the Bank's trading portfolios and ensures they remain within the loss limits determined, calculated and estimated by the Market Risk Area. The trading portfolio (measured at fair value through profit or loss) consists mainly of those investments measured at fair value, free of any restriction on their immediate sale and which are often bought and sold by the Bank to sell them in the short term to benefit from short-term price movements. The Financial Management's portfolios (measured at fair value through other comprehensive income) include all financial investments not considered in the trading portfolio.

The roles that concern the trading portfolio comprise the following:&nbsp;&nbsp;&nbsp;&nbsp;

i.applying Value-at-Risk (VaR) techniques to measure interest rate risk,&nbsp;&nbsp;&nbsp;&nbsp;

ii.adjusting trading portfolios to market and the measurement of daily profit and loss from trading activities,

iii.comparing the actual VAR with the established limits,

iv.establishing loss control procedures for losses above predetermined limits, and &nbsp;&nbsp;&nbsp;&nbsp;

v.providing information on trading activities to the ALCO, other members of the Bank's management, and the Global Risk Department.

The functions regarding financial management portfolios entail the following:

i.Applying sensitivity simulations (as explained below) to measure the interest rate risk of local currency activities and the potential loss predicted by these simulations and

ii.Providing the respective daily reports to the ALCO, other members of the Bank's Management, and the Global Risk Department.

***Market risk – Trading portfolio***

The Bank applies VaR methodologies to measure exchange rate risk and sensitivity to interest rates of the trading portfolio. The Bank has a consolidated commercial position comprised of fixed income investments and foreign currency trading. This portfolio is essentially composed of bonds from the Central Bank of Chile, mortgage bonds and low risk locally issued corporate bonds. At the end of the year, the trading portfolio did not contain investments in equity.

For the Bank, the VaR estimate is carried out using a historical simulation methodology, which consists of observing the behavior of the losses and gains that would have occurred with the current portfolio using the market conditions of a predetermined historical period. From that information, the maximum loss is inferred with a certain level of confidence. The methodology has the advantage of accurately reflecting the historical distribution of market variables and of not requiring any specific probability distribution assumptions. All VaR measures are intended to determine the distribution function for the change in the value of a given portfolio, and once this distribution is known, to calculate the percentile related to the necessary confidence level, which will be equal to the value at risk in virtue of those parameters. As calculated by the Bank, the VaR is an estimate of the maximum expected loss of the market value of a given portfolio over a 1-day horizon at a confidence level of 99.00%. It is the maximum one-day loss that the Bank could expect to suffer on a given portfolio with the 99.00% confidence level. In other words, it is the loss that the Bank would expect to exceed only 1.0% of the time. VaR provides a single estimate of market risk that is not comparable from one market risk to another. Returns are calculated using a time window of 2 years or at least 520 data points obtained from the VaR calculation reference date backward in time.

The Bank does not calculate three separate VaRs. Instead, a single VaR is calculated for the entire trading portfolio, further segregated by risk type. The VaR program performs a historical simulation and calculates a Profit and Loss (P&L) statement for 520 data points (days) for each risk factor (fixed income, foreign exchange and equities). Then, the P&L of each risk factor is added together, and a consolidated VaR is calculated with 520 data points or days of data. Simultaneously, the VaR is calculated for each risk factor based on the individual P&L calculated for each factor. Moreover, a weighted VaR is calculated similarly, as described above, but gives a higher weighting to the most recent 30 data points. As a result, the higher of the two VaRs is reported. The Bank uses VaR estimates to warn if statistically estimated losses in the trading portfolio exceed prudent levels and, therefore, certain predetermined limits are in place.

***Limitations of the VaR model***

In applying this methodology for calculation, no assumptions are made about the distribution probability of changes in the risk factors; instead, the historically observed changes are used to generate scenarios for the risk factors under which each portfolio item will be valued. The definition of a valuation function fj (xi) for each instrument j is necessary, preferably the same as the one used to calculate the market value and daily position results. This valuation function shall be applied to generate simulated prices for all instruments in each scenario.

Furthermore, the VaR methodology should be interpreted considering the following limitations:

• Market rate and price changes may not consist in independent and identically distributed random variables, nor may they have a normal distribution. The normal distribution assumption, in particular, may underestimate the probability of extreme market movements.

• The historical data used by the Bank may not provide the best estimate of future joint distribution of changes in risk factors. Any modification of the data may be inappropriate. In particular, the use of historical data may fail to capture the risk of possible extreme and adverse market fluctuations regardless of the time frame used;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• A 1-day time horizon may not fully capture those market risk positions that cannot be liquidated or hedged within one day. It would not be possible to liquidate or hedge all positions in one day;

• The VaR is calculated at the end of negotiations, but trading positions may change substantially during the trading day;&nbsp;&nbsp;&nbsp;&nbsp;

• The use of a 99% confidence level does not consider or make any representation about losses that may occur beyond this confidence level, and

• The VaR model does not capture all the complex effects of risk factors on the value of positions or portfolios and, therefore, may underestimate potential losses.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

As of September 30, 2025, and December 31, 2024, the Bank did not exceed the VaR limits of the trading portfolio's, considering the three components: fixed-income, equity, and foreign currency investments.

The Bank performs back-testing daily and generally finds that trading losses exceed the estimated VaR almost once every 100 trading days. At the same time, a limit was set on the maximum acceptable VaR on the trading portfolio. As of September 30, 2025, and December 31, 2024, the Bank has remained within its VaR threshold, even in instances where the actual VaR exceeded the estimated VaR.

***Market risk – Local and foreign financial management***

The Bank's financial management portfolio includes most of the Bank's assets and non-trading liabilities, including the loan portfolio. The Bank's commercial strategies (structural risk) heavily influence these portfolios' investment and funding decisions.

The Bank uses sensitivity analysis to measure the market risk of local and foreign currency (not included in the trading portfolio). The Bank conducts a scenario simulation, which is calculated as the difference between the present value of the flows in the chosen scenario (curve with a parallel movement of 100 bps in all segments) and their value in the baseline scenario (current market). All items in local currency indexed to inflation (UF) are adjusted by a sensitivity factor of 0.57, representing a yield curve shift by 57 basis points in real rates and 100 basis points in nominal rates. The same scenario is conducted for net foreign currency positions and interest rates in US dollars. The Bank has also set limits on the maximum loss these interest rate movements can have on budgeted capital and net interest income for the year. To determine the consolidated limit, the foreign currency limit is added to the local currency limit for both the net financial loss limit and the capital loss and reserves limit using the following formula:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

Bounded limit = square root of a2 + b2 + 2ab, in which:

a: limit in national currency.&nbsp;&nbsp;&nbsp;&nbsp;

b: limit in foreign currency.

Since it is assumed that the correlation is 0. 2ab = 0.

***Limitations of sensitivity models***

The most important assumption is using a change of 100 basis points in the yield curve (57 basis points for real rates). The Bank uses a change of 100 basis points as sudden changes of this magnitude are considered realistic. In addition, the Global Risk Department has also established comparable country limits to compare, monitor and consolidate market risk by country in a realistic and orderly manner.&nbsp;&nbsp;&nbsp;&nbsp;

Furthermore, the methodology of sensitivity simulations should be interpreted considering the following limitations:

• The scenario simulation assumes that the volumes remain on the Bank's Interim Consolidated Statements of Financial Position and are always rolled over at maturity, omitting the fact that certain credit risk considerations and prepayments may affect the maturity of certain items.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

• This model assumes an equal change across the entire yield curve and does not consider different movements for different maturities.

• The model does not consider the sensitivity of volumes resulting from changes in interest rates.

Limits on budgeted finance income losses are calculated based on expected finance income for the year that cannot be obtained. This means the actual percentage of finance income at risk could be higher than expected.

***Inflation risk***

The Bank has readjustable assets and liabilities according to the variation of the Unidad de Fomento (UF). The Bank has, in general, more assets than liabilities in UF. Therefore, moderate rises in inflation have a positive effect on interest income from inflation adjustments, while a fall in the UF value negatively impacts the Bank's net interest margin. To manage this risk, the Assets and Liabilities Committee limits the difference between UF-denominated assets and liabilities, which may not exceed 30% of the Bank's interest-earning assets. Financial Management manages this mismatch on a day-to-day basis, and the limits are calculated and monitored by the Market Risk Division.

***Market Risk items and their measurement***

Market Risk Exposure is measured and monitored using the difference between the foreign currency asset and liability balances (net position) and the cash flows payable (associated with liability items) and cash flows receivable (associated with asset items) in the Trading and Banking Books for a given period. Foreign currency items and term mismatches are exposed to different adjustment factors, sensitivities, and rate changes. The Board of Directors of Banco Santander Chile presented and approved the Market Risk Exposure Policy on a Standardized Basis.

The following risks will determine Market Risk Exposure:

-Interest Rate Risk.

-Foreign exchange Risk.

-Readjustment (Inflation) Risk.

-Currency Options Risk.

To fulfill its functions, the Integral Risk Committee works directly with the Bank's control and risk departments whose joint objectives include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Evaluate those risks that, due to their size, could compromise the Bank's solvency, or that potentially present significant operational or reputational risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ensure that the Bank is equipped with the means, systems, structures and resources in accordance with the best practices that allow the implementation of the risk management strategy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ensure the integration, control and management of all the Bank's risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• execute the application throughout the Bank and its businesses of homogeneous risk principles, policies and metrics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop and implement a risk management model in the Bank, so that risk exposure is adequately integrated into the different decision-making processes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identify risk concentrations and mitigation alternatives, monitor the macroeconomic and competitive environment, quantifying sensitivities, and the foreseeable impact of different scenarios on risk positioning; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• manage the structural risks of liquidity, interest rates and exchange rates, as well as the Bank's own funding base.

To meet the aforementioned objectives, the Bank (Management and ALCO) carries out several activities related to risk management, which include: calculating the risk exposures of the different portfolios and/or investments, considering mitigating factors (guarantees, netting , collaterals, etc.); calculate the probabilities of expected loss for each portfolio and/or investments; assign loss factors to new operations (rating and scoring); measure the risk values of portfolios and/or investments based on different scenarios through historical simulations; establish limits on potential losses based on the different risks incurred; determine the possible impacts of structural risks on the Bank's Interim Consolidated Statements of Financial Position; set the limits and alerts that guarantee the Bank's liquidity; and identify and quantify operational risks by business lines and thus facilitate their mitigation through corrective actions.

**LIQUIDITY RISK**

This refers to the possibility that an entity may not be able to meet its payment commitments or may have to resort to raising funds on burdensome terms.

**Liquidity risk management&nbsp;&nbsp;&nbsp;&nbsp;**

The Bank's approach to liquidity management is to ensure, to the extent possible, that it always has sufficient resources to meet its obligations as they fall due under normal circumstances and stress conditions without incurring unacceptable losses or risking damage to the Bank's reputation.

The Financial Management area manages liquidity risk by using a portfolio of liquid assets to ensure that the Bank always maintains sufficient liquidity to cover short-term fluctuations and long-term funding while complying with internal liquidity regulatory requirements. The Financial Management area receives information from all business units on the liquidity profile of their financial assets and liabilities, as well as a breakdown of other projected cash flows from future business. Based on this information, the area maintains a portfolio of short-term liquid assets, consisting mainly of liquid investments, loans and advances to other banks, to ensure that the Bank has sufficient liquidity. The liquidity needs of the business units are covered by short-term transfers from Financial Management to cover short-term fluctuations and long-term funding to meet all structural liquidity needs.

Accordingly, the Board sets limits on a minimum portion of maturing funds available to meet such payments and on a minimum level of interbank operations and other lending facilities that should be available to cover unexpected demands for withdrawals of liquidity. This is reviewed periodically by the ALCO whose functions include monitoring the strategies to manage liquidity risk. Setting these limits is conceived as a dynamic process that responds to the level of risk appetite deemed acceptable by the Bank and its entities.

The system of limits is sufficiently robust to be aware at all times of the level of exposure that each institution is incurring in, in terms of liquidity risks.

Besides the limits, the Bank includes alert indicators by the concentration of counterparties, type of products, and maturities in its management to diversify the funding sources and their maturity structure.

The Bank monitors its liquidity position daily, determining future inflows and outflows. Furthermore, stress tests are performed at the end of each month, using a variety of scenarios covering both normal market conditions and market fluctuation (stress) conditions.

The Bank has a structure of internal liquidity limits that Financial Management and the Treasury must respect at all times. Market Risk Management calculates and monitors the consumption of internal limits, verifies compliance with them and communicates their status to senior management and the Board of Directors.

At the beginning of each calendar year, these limits are proposed by Market Risk Management, approved locally at the ALCO and then ratified at the highest Board level.

Liquidity limits and early warning indicators, and internally defined management measures can be differentiated into the following three groups:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Limits associated with concentration and mismatches of cash flows and liquidity of the Bank's operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity Management Tools, known as Structural Liquidity or Funding Tables, are used to determine the Bank's structural liquidity position. It also permits the Bank to actively manage its structural liquidity, since this is an essential mechanism to ensure a permanent funding of assets under optimal conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Early warning indicators are linked with concentration risks and are used as tools for detecting and anticipating potential liquidity stress situations and, if necessary, activating the Liquidity Contingency Plan.

The Market Risk Area establishes and updates the Bank's Liquidity Management Policy (LMP). Reviews and possible updates are conducted once a year. Nevertheless, it may be updated at the request of any areas affected by the LMP that have identified the need for modification. The Board approves the contents of the LMP.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

The Market Risk Area provides all the necessary tools for the statistical analysis required by local liquidity regulations. It also assesses, at least once a year, whether the models are still valid. The Board of Directors must approve the conclusions of this analysis.

In periods of normal liquidity, Financial Management applies policies and makes arrangements to keep the Bank within internal and regulatory limits.

If a crisis has been identified, even at its mildest level, the Liquidity Crisis Committee applies the necessary policies to deal with potential liquidity shortfalls or restrictions, creates contingency plans to manage emergencies quickly, and reports such situations to senior management and the respective committees.

**Liquidity risk measurement and control**

***1.Maturity mismatches subject to regulatory limits***

The Regulatory Liquidity Ratio measures and limits the mismatches of net income flows relative to capital. Under current regulations, the 30-day mismatch cannot exceed the Bank's core capital for both domestic and foreign currency by one time, and the 90-day mismatch cannot exceed it by two times.

***2.Monitoring indicators and liquidity ratios subject to regulatory limits***

An important component of liquidity risk management is High-Quality Liquid Assets (HQLA). These are balance sheet assets, mainly consisting of financial investments that are not pledged as collateral, have low credit risk, and have a deep secondary market. According to Basel III standards, these assets are divided into three tiers, with Tier 1 assets being the most liquid and Tier 3 the least liquid. Tier 1 assets are mostly composed of bonds from the Republic of Chile, the Central Bank of Chile, and the United States Treasury.

| Tier 2: fixed income | 3499 | 4517 |
| **Total** | **7311310** | **9662647** |

---

***3.Liquidity Coverage Ratio (LCR)***

The Liquidity Coverage Ratio (LCR) measures liquid assets over 30-day net cash outflows. It is used by banks globally as part of the Basel III standards. Chilean banks were required, starting in 2019, to meet a minimum level of 60%, which was to gradually increase to 100% by 2022. For the 2025 fiscal year, a minimum level of 100% continues to be mandated.

The objective of the LCR is to promote the short-term resilience of banks' liquidity risk profiles. To this end, the LCR ensures banks have an adequate pool of unencumbered High-Quality Liquid Assets, which can be easily and immediately converted into cash in the private markets to cover short-term liquidity needs.

***5.Information on liquidity position per the requirements of the Central Bank of Chile***

**i.Maturity mismatches**

The Central Bank of Chile published on March 8, 2022, Rules on the Management and Measurement of the Liquidity Position of Banks, which modernized liquidity regulation, aligning the published regulatory requirements of the FMC to Basel III standards.

According to the Central Bank, the liquidity position is measured and monitored through the difference between cash flows payable, which are associated with liability and expense account items, and cash flows receivable, which concern asset and income account items, for a given period or time frame, referred to as the maturity mismatch.

The liquidity policy on an Adjusted Basis was presented and approved by the Board of Directors of Banco Santander-Chile. Maturity mismatch calculations are performed separately for domestic and foreign currencies.

Maturity mismatches shall be made in the following time frames:

&nbsp;&nbsp;&nbsp;&nbsp;• First time frame: up to 7 days inclusive.

&nbsp;&nbsp;&nbsp;&nbsp;• Second time frame: between 8 days and 15 days inclusive.

&nbsp;&nbsp;&nbsp;&nbsp;• Third time frame: between 16 and 30 days inclusive.

The Chilean Central Bank has statutory powers allowing it to demand banks to hold reserves of up to 40% on average for demand deposits and up to 20% for time deposits to implement monetary measures. Furthermore, as the aggregate amount of demand deposits exceeds 2.5 times the bank's regulatory capital, the bank must maintain a 100% 'technical reserve' against them in bonds and Central Bank's notes.

As of September 30, 2025, and December 31, 2024, the Central Bank required the Bank to maintain a technical reserve of Ch$0 for both periods.

The volume and composition of liquid assets are presented in item 2 above.

The liquidity coverage ratio is presented in item 3 above.

**6. Maturity analysis of financial liabilities**

The remaining contractual maturities of financial liabilities are provided in Note 45.

The liquidity management inherent in derivative and non-derivative financial liabilities is managed through various levers that enable this risk to be kept in line with the profile defined by the Bank while at the same time making efficient use of available liquidity. To this end, a high level of liquid assets is maintained, and the level of expected short-term income and expenditure is monitored daily, thus avoiding high concentrations of maturities. On the other hand, a very diversified funding matrix is maintained, both across product types and customer types.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

**OPERATIONAL RISK**

Operational risk is defined as the risk of loss due to defects or failures of internal processes, employees and systems or external events. It covers risk categories such as operational incidents, cloud computing, cyber security, business continuity, and outsourced services, both and strategic and non-strategic.

Operational risk is generated in all business and support areas and is inherent to all products, activities, processes and systems. For this reason, all employees are responsible for managing and controlling the operational risks generated by their activities. Our operational risk control and management model is based on a continuous process of identifying, assessing and mitigating risk sources, whether or not they have materialized, ensuring that risk management priorities are properly established.

**Operational risk management**

The operational risk model regulates the necessary elements for adequate management and control of operational risk, aligned with compliance with advanced regulatory standards and best management practices, and includes the following phases:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• strategy and planning;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identification, assessment and monitoring of risks and internal controls;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• implementation and monitoring of mitigation measures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• availability of information, adequate reporting and escalation of relevant issues.

The main operational risk tools used are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Internal events database. Recording operational risk events with financial impact (all losses are recorded, regardless of their amount) or non-financial impact (such as the regulatory impact on customers and/or services). This information:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• allows root-cause analysis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• raises awareness of risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enables the escalation of relevant operational risk events to the senior management of the Risk Division with maximum immediacy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• facilitates regulatory reporting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Self-assessment of operational risks and controls. A qualitative process that assesses the main operational risks related to each function, the state of the control environment and their assignment to the different functions within the Bank, using the judgment and experience of a panel of experts from each function.

The objective is to identify and assess material operational risks that could prevent business or support units from achieving their objectives. Once the risks and the internal controls that mitigate them have been assessed, mitigating measures are identified if risk levels are above tolerable.

This process integrates specific operational risk reviews that allow for comprehensive and widespread identification of risks, especially technological risks, fraud, supplier risks and factors that could lead to other operational risks and specific regulatory non-compliance.

&nbsp;&nbsp;&nbsp;&nbsp;• External events database. This involves quantitative and qualitative information of external operational risk events. The database allows for a detailed and structured analysis of relevant events in the sector, comparing the loss profile and the proper preparation of self-assessment exercises and scenario analysis.

&nbsp;&nbsp;&nbsp;&nbsp;• Analysis of operational risk scenarios. Its objective is to identify events with an extremely low probability of occurrence that could generate significant losses for the Bank and establish appropriate mitigation measures through the assessment and expert opinion of the business lines and risk managers.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

• A statement establishing the Bank's commitment to controlling and limiting non-financial risk events that lead to or could lead to financial losses; fraud events; operational and technological incidents; legal and regulatory breaches; conduct issues, or reputational damage. Although a certain volume of losses is expected, unexpected high-severity losses due to a failure of controls are not acceptable.

• Internal audit, external audit and regulators' recommendations. They provide relevant independent information on inherent and residual risk and identify areas for improvement in controls and processes.

• Capital model. This is a model that captures the Bank's risk profile, based primarily on information gathered from the internal loss database, external data and scenarios. The main application of the model is to determine the economic capital for operational risk and the estimation of expected and stressed losses, which are used in the operational risk appetite.

• Other specific tools to further analyze and manage operational risks include assessing new products and services, managing business continuity plans, and updating the operational risk program's perimeter and quality review processes.

The Bank's operational risk management and reporting system support programs and tools focusing on governance, risk and compliance. It provides information for management and reporting and helps improve decision-making in operational risk management by consolidating information, simplifying the process, and avoiding duplication.

**Operational continuity plan**

Digital transformation is revolutionizing the way banks operate, presenting new business opportunities while also giving rise to a wide range of emerging risks, such as technology risks, cyber risks and an increasing reliance on suppliers, which increases exposure to events that may affect the delivery of services to our customers.

The Bank is highly committed to ensuring robust control of the environment as determined by the best industry standards. This seeks to strengthen our operational resilience to potentially disruptive events, thereby ensuring adequate service delivery to our customers and system stability.

One of the main pillars is a business continuity management system aimed at ensuring the continuity of business processes in the event of a disaster or major incident. This process identifies the potential impacts that threaten the entity, supplying the correct protocols and governance to ensure an effective response capability. Its main objectives are:

&nbsp;&nbsp;&nbsp;&nbsp;• To protect the integrity of people in a contingency situation.

&nbsp;&nbsp;&nbsp;&nbsp;• To ensure that core functions are performed, and the impact on service delivery to our customers is minimized in contingency events.

&nbsp;&nbsp;&nbsp;&nbsp;• To meet the Bank's obligations to its employees, customers, shareholders and other stakeholders.

&nbsp;&nbsp;&nbsp;&nbsp;• To comply with regulatory obligations and requirements.

&nbsp;&nbsp;&nbsp;&nbsp;• To minimize the entity's potential financial losses and impact on the business.

&nbsp;&nbsp;&nbsp;&nbsp;• To protect the brand image, credibility and trust in the entity.

&nbsp;&nbsp;&nbsp;&nbsp;• To reduce operational effects by providing effective procedures, priorities, and strategies for recovering and restoring business operations following a contingency.

&nbsp;&nbsp;&nbsp;&nbsp;• To contribute to stabilizing the financial system.

The pandemic challenged the business continuity planning frameworks and strategies. While some protocols had to be adapted, this crisis demonstrated that the Bank has a robust Business Continuity Management system.

**NOTE 47 - RISK MANAGEMENT AND REPORTING, continued**

**Relevant mitigation measures**

The Bank implements and monitors mitigation measures related to the main sources of risk through internal operation risk management tools and other external sources of information. Business transformation and digitalization bring new risks and threats, such as increased payment fraud and origination (credit) fraud. We improved control mechanisms and designed new products to mitigate these risks.

Strong authentication processes in the customer enrollment process and the reinforcement of anti-fraud alerts in origination are increasingly widespread resources to mitigate the risk of fraud.

In the case of cards, the use of chip and PIN cards in shops and ATMs, two-step authentication with one-time passwords (dynamic verification passwords), reinforced security at ATMs through the incorporation of physical protection and anti-skimming elements, as well as improvements in the logical security of these devices.

In the case of Internet banking, verification of online banking transactions with a second security factor of one-time passwords, implementation of specific protection measures for mobile banking, such as identification and registration of customer devices, monitoring of the security of the e-banking platform to prevent attacks on the systems, among others.

**Cybersecurity**

Cybersecurity threats are expected to increase. The financial sector is expected to be one of the main targets. With the increased reliance on digital systems, cybersecurity is one of the main non-financial business risks. Therefore, our goal is to make the Bank a cyber-resilient organization that can quickly resist, detect, and respond to cyber-attacks by constantly evolving and improving its defenses. In this area, the Bank continues to develop its control and monitoring framework in line with the best international practices.

**Outsourcing of services**

In order to be consistent with our digitization strategy, the Bank aspires to present its customers with the best solutions and products on the market. This implies increasing services provided by third parties and the intensive use of new technologies such as cloud services. In addition, due to increasing cyber risks and regulatory requirements, we have updated and strengthened the supplier management framework, internal control framework and risk culture to ensure that risks associated with third-party procurement are properly assessed and managed.

The Bank has identified the suppliers that could present a higher level of exposure to our operations and the services provided to our customers. Accordingly, it has reinforced the monitoring of these suppliers to ensure that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• They have an appropriate control environment, depending on the level of risk of their service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Business continuity plans are in place to ensure service delivery in case of disruptive events.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• They have controls to protect sensitive information processed during the delivery of their services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Contracts and agreements with third parties include the necessary clauses to protect the interests of the Bank and our clients, while at the same time covering existing legal obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• There are exit strategies, including service reversion or migration plans, in the case of services with a strong impact on business continuity and high replacement complexity.

**Insurance**

To address operational risk and other risk types generated by the Bank's own operations, insurance has been procured for property damage, general civil liability, fraud, expenses arising from cybersecurity breaches, and third-party claims against executives, among others.

**NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS**

As of September 30, 2025, and 2024, and as of December 31, 2024

**NOTE 48 - INFORMATION ON REGULATORY CAPITAL AND CAPITAL ADEQUACY INDICATORS**

**General Information**

The Bank provides information on the objectives, policies, and processes for managing capital and regulatory capital, respectively, in accordance with paragraphs 134–136 of IAS 1.

**Capital Description**

The Conceptual Framework establishes a concept of Financial Capital and one of Physical Capital. In this regard, the Bank applies the concept of Financial Capital, which translates into the consideration of invested money or invested purchasing power; capital is synonymous with the entity's net assets or equity.

The definition of regulatory capital was changed in December 2021, and is now defined as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Paid-in capital from subscribed and paid common shares of the Bank;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Premium paid for instruments included in this component of capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reserves, whether from earnings or not, from depreciation of perpetual bonds and expiry of perpetual bonds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Items under "other accumulated comprehensive income";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Retained earnings from prior periods, profit (loss) for the year, net of provisions for minimum dividends, revaluation of perpetual bonds, and payment of interest and/or dividends on regulatory capital financial instruments issued;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-controlling interest as indicated in the CASB.

**Objectives**

The Bank's main objectives in Capital Management include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Meeting internal capital and capital adequacy goals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Complying with regulatory requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Aligning the Bank's strategic plan with the capital expectations of external stakeholders (rating agencies, shareholders and investors, clients, supervisors, etc.);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Supporting business growth and any strategic opportunities that may arise.

**Policies**

The Bank has an Asset and Liability Committee (ALCO), which is responsible for supervising, authorizing, establishing policies, and evaluating all aspects related to capital and solvency. The Board of Directors has delegated to ALCO the oversight and assessment of capital levels and returns consistent with the Bank's strategy. The Risk and Compliance Committee (IRC) monitors and is responsible for the primary and secondary metric limits based on the risk appetite. Additionally, the Bank has developed the necessary policies to support the management and fulfillment of capital management strategies and objectives, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capital Adequacy Policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capital Planning Policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Policy for Managing Capital Deterioration Situations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capital Monitoring Policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Dividend Policy and Basel III Implementation.

**NOTE 48 - INFORMATION ON REGULATORY CAPITAL AND CAPITAL ADEQUACY INDICATORS, continued**

&nbsp;&nbsp;&nbsp;&nbsp;**Capital Management Processes**

Capital is managed in accordance with the risk environment, Chile's economic performance, and the economic cycle. The relevant Committee may adjust our current capital policies to address changes in the aforementioned risk environment.

Capital management is based on a Capital Framework aimed at ensuring that the level, structure, and composition of capital are adequate at all times, considering the Bank's risk profile and various scenarios. This framework ensures compliance with both minimum regulatory requirements and the Bank's risk appetite and Recovery Plan, aligning with the interests of all stakeholders and supporting the growth strategy defined by the Bank.

The capital model defines the functional and governance aspects related to capital planning, budget execution and monitoring, capital adequacy analysis, capital measurement, and capital-related reporting and disclosure. This model covers the main capital management activities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Setting solvency and capital contribution targets aligned with minimum regulatory requirements and internal policies, to ensure a solid capital level consistent with the Bank's risk profile, and efficient use of capital to maximize shareholder value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Developing a capital plan to meet these objectives in line with the strategic plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Assessing capital adequacy to ensure the capital plan aligns with the Bank's risk profile and risk appetite (including stress scenarios).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.Developing the capital budget as part of the Bank's budgeting process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.Monitoring and controlling budget execution and developing action plans to correct any deviations from the budget.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.Calculating capital metrics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.Preparing internal capital reports, as well as reports for supervisory authorities and the market.

**Compliance with Capital Management Objectives**

The Bank continuously evaluates its risk-return ratios through its core capital, effective equity, economic capital, and return on capital. Regarding capital adequacy, the Bank conducts its internal process based on the FMC standards in effect since December 1, 2021 (Basel III). Economic capital refers to the capital required to support all the risk arising from business activities at a given level of solvency.

Monitoring and tracking of metrics and their limits are carried out by the ALCO, which also performs a monthly evaluation of capital levels and risk appetite. Additionally, it oversees the solvency indicator "Regulatory Capital / Risk-Weighted Assets," which is monitored both on a Phased-in and Fully Loaded basis, with the latter considering capital requirements at 100% enforceability.

**Quantitative Data on Capital Management**

The Bank primarily manages its capital by increasing its effective equity through the accumulation of earnings. This approach enables it to maintain a minimum regulatory capital-to-risk-weighted-assets ratio of 16.66%, which is 440.5 basis points above the required minimum

**When is an Entity is Subject to External Requirements**

***Minimum Required Capital***

According to the General Banking Law, a bank must maintain a minimum of UF 800,000 (approximately Ch$31,589 million or US$33 million as of September 30, 2025) in paid-in capital and reserves, calculated in accordance with FMC regulations.

*Capital Requirements*

According to the new General Banking Law (as updated by Law 21,130), the minimum capital requirements have increased both in amount and quality. The total regulatory capital remains at 8% of risk-weighted assets, but now includes credit, market, and operational risks. The minimum Tier 1 capital requirement has increased from 4.5% to 6% of risk-weighted assets, of which up to 1.5% can consist of Additional Tier 1 (AT1) capital—such as preferred shares or perpetual bonds, which may be convertible into common shares. Tier 2 capital is now set at 2% of risk-weighted assets. Chapter 21-1 of the UCBR defines the components of regulatory equity.![image.jpg](image.jpg)

Additional capital demands have been incorporated through a capital conservation buffer of 2.5% of risk-weighted assets (UCBR 21-12). Furthermore, the Central Bank of Chile, with prior agreement from the FMC, may establish an additional countercyclical buffer of up to 2.5% of risk-weighted assets, in accordance with FMC regulations (UCBR 21-12). Both buffers must be composed of core capital. In addition, the FMC, with the favorable agreement of the Board of the Central Bank of Chile (BCCh), has the authority to establish new regulatory methodologies for calculating risk-weighted assets related to: Credit risk (UCBR 21-6), Market risk (UCBR 21-7), and Operational risk (UCBR 21-8). This authority also extends to: conditions for the issuance of hybrid AT1 instruments, capital charges for domestically systemically important banks (D-SIBs), prudential deductions from regulatory capital, imposition of additional measures, including increased capital, for banks with deficiencies in their Supervisory Review and Evaluation Process (SREP or Pillar II). Pillar II aims to ensure that banks maintain a capital level appropriate to their risk profile and encourages the development and use of effective risk monitoring and management processes. Banks are responsible for conducting an Internal Capital Adequacy Assessment Process (ICAAP), while supervisors must review these strategies and internal evaluations. If supervisors are not satisfied with the outcomes, they may intervene early. This can include requiring capital above the minimum regulatory threshold, especially to ensure resilience in adverse credit cycles.

The result was a simplified report with the conclusions of the self-assessment process, which in its first version in 2021 only included credit risk, in 2022 included Pillar I risks, and in 2023 the full report was required. On April 11, 2025, the FMC issued Exempt Resolution No. 3,612 applying additional capital requirements under Pillar II, in which the commission's board resolved to apply capital requirements of 0.25%, which the Bank must comply with 50% by June 2025.

According to the General Banking Law, banks must maintain a regulatory capital of at least 8% of risk-weighted assets, net of required credit losses, and a requirement for paid-in capital and reserves ("core capital") of at least 3% of total assets, also net of credit losses. Regulatory capital is defined as the aggregate of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The bank's paid-in capital and reserves, excluding capital attributable to subsidiaries and foreign branches, or core capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Perpetual bonds and preferred shares referred to in Article 55 bis of the GBL, issued by the bank and valued at the issuance price, up to one-third of its core capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Subordinated bonds, valued at their issuance price, with a 20% annual reduction starting six years before maturity, up to 50% of its core capital; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Additional provisions for credit losses, up to 1.25% of credit risk-weighted assets.

On April 1, 2025, the FMC announced the annual classification of systemically important banks and established corresponding requirements. In this announcement, the Commission's board approved Resolution No. 3,143, which maintains the classification for another year, thereby sustaining the requirement for an additional 1.5% core capital charge for the Bank.

On April 1, 2025, the FMC announced the annual classification of systemically important banks and established corresponding requirements. In this announcement, the Commission's board approved Resolution No. 3,143, which maintains the classification for another year, thereby sustaining the requirement for an additional 1.5% core capital charge for the Bank.

On April 14, 2025, the FMC reported on the application of the Pillar II capital requirement. The announcement states that the Board approved Resolution No. 3,612 regarding this application. The additional capital requirement is 0.25 percent, of which 50 percent must be applied no later than June 30, 2025.

At its Financial Policy Meeting on November 19, 2024, the Board of the Central Bank of Chile decided to maintain the Countercyclical Capital Buffer (CCyB) at 0.5% of risk-weighted assets. This buffer was initially activated on May 24, 2023, as announced by the FMC, following the first semester 2023 Financial Policy Meeting of the Central Bank. At that time, the Board of the Central Bank agreed to activate the CCyB at a level of 0.5%, to become enforceable within one year, with the unanimous prior favorable opinion of the FMC. The decision was taken as a precautionary measure in response to increased external financial uncertainty.

**Compliance with external requirements**

Regulatory capital and core capital are calculated based on the Consolidated Interim Financial Statements prepared in accordance with the CASB issued by the FMC. As a result of the merger between two predecessor institutions with a significant market share in the Chilean financial market, our current minimum regulatory requirement consists of a minimum regulatory capital-to-risk-weighted assets ratio of 12.25%, As of the reporting date, the Bank maintains a regulatory capital-to-risk-weighted assets ratio of 16.66%.

**Other Announcements and Statements**

In January 2019, a new version of the GBL was published. Among the most significant changes was the adoption of capital levels aligned with Basel III standards. In 2020, the final versions of the regulations governing the new capital models for the Chilean banking sector were released.

Pillar III promotes market discipline and financial transparency through the disclosure of meaningful and timely information. This enables users to better understand the risk profile and capital structure of local banking institutions, thereby reducing information asymmetries.

On July 8, 2025, the FMC published Circular No. 2,365 - Adjustments to Chapter 21-13 of the UCBR for the determination of additional regulatory capital requirements for banking entities, as a result of the supervisory process known as Pillar II of Basel III. The new regulatory adjustments published introduce improvements to Chapter 21-13 of the UCBR , with the objective of facilitating the supervisory process and clarifying some aspects of the capital evaluation process. The adjustments will be incorporated partially, with an initial application starting with the reports reported in December 2025 and will finalize in the review of the ICAAP, which will be delivered in April 2027.

**NOTE 48 - INFORMATION ON REGULATORY CAPITAL AND CAPITAL ADEQUACY INDICATORS, continued**

i.In the case of leverage, the minimum level is 3%, without prejudice to additional requirements for systemically important banks, which may be set in accordance with the provisions of Chapter 21-30 of the UCBR. In the case of core capital, the bank must consider a limit of 4.5% of risk-weighted assets (RWA). Additionally, where applicable, the bank must add the current systemic surcharge according to transitional provisions, as well as the Pillar 2 requirement defined at this level of capital. For new banks that do not have paid in capital up to 400,000 UF, an additional 2% must be added to the minimum requirement in accordance with Article 51 of the GBL. This value decreases to 1% if the paid-in capital exceeds 600,000 UF but is less than 800,000 UF. In the case of Tier 1 capital, the bank must consider a minimum requirement of 6%, plus any Pillar 2 charge defined at this capital level. Finally, at the level of regulatory capital, the bank must consider a minimum requirement of 8% of RWA. To this value, additional charges for Pillar 2, systemic banks, and those indicated in Article 51 of the LGB for new banks must be added.

ii.The capital buffer shortfall must be estimated in accordance with Chapter 21-12 of the UCBR. This value defines the restriction on dividend distribution if positive, as stipulated in the aforementioned Chapter. In the case of effective equity, the value of the conservation and countercyclical buffer in effect as per the transitional provisions at the reporting date must be added, along with the value defined in note a), even if a requirement under Article 35 bis of the GBL exists.

iii.If the bank has an effective equity requirement in effect under Article 35 bis of the GBL, it must report its value in this cell in accordance with the transitional provisions.

iv.This corresponds to the solvency classification as established in Article 61 of the GBL.

v.There is a limit of 1.25% if the bank uses standard methodologies (field T1_8.a), or 0.625% if the bank uses internal methodologies (field T1_8.b), in the estimation of RWA for credit risk (CRWA).

vi.Subordinated bonds counted towards Tier 2 capital must not exceed 50% of Common Equity Tier 1 (CET1), considering the deductions applied to these instruments as per Chapter 21-1 of the UCBR.

vii.Additional Tier 1 capital (AT1) must not exceed one-third of CET1.

viii.Additional provisions and subordinated bonds allocated to AT1 must not exceed 0.5% of RWA as of December 1, 2022, according to the transitional provisions of Chapter 21-2 of the UCBR.

ix.According to the transitional provisions, from December 1, 2022, solvency requirements also apply at the local consolidated level. Figures at this level must be reported in this column. Banks without foreign subsidiaries are not required to complete this data.
