Banco Santander-Chile
A bank that serves as one of Chile's largest, offering everyday banking for individuals and small businesses — checking and savings accounts, personal and auto loans, mortgages, and credit cards. It has operated in Chile since 1978, and in 2002 a merger between Banco Santiago and the original Santander-Chile created today's bank. Its name comes from the Spanish port city of Santander, which itself honors Saint Emeterius.

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.” 153 Table of contents Risk Department All issues regarding risk in the Bank are the responsibility of the Bank’s Risk Department. The Risk Department reports to the CEO but has full independence, and no risk decisions can be made without its approval. The following diagram illustrates the governance of our risk division including the committees with approval power: Below is an organizational chart of the Risk Department: 1.Credit Risk The impairment model applies to all financial assets measured at amortized cost and fair value through other comprehensive income (FVOCI), including commitment and contingent loans. Investments in equity are outside of the scope of the new impairment requirements. For more information, see “Item 5 Operating and financial review and prospects—Critical Accounting Policies.” The Bank has defined default on the following basis: •Corporate: when exposure is more than 89 days past due, it has been restructured, it is in judicial collection, pulling effect defined as the entire outstanding amount on any loan which has an installment 90 days or more past due. 154 Table of contents •Other: when exposure is more than 89 days past due, it has been restructured, it is in judicial collection, it has been written off, or has been identified as impaired by an internal risk committee. An exposure will be considered as defaulted when the past-due amounts of an exposure exceed materiality thresholds for 89 or more consecutive days. The Bank considers reasonable and supportable information that is available without undue cost or effort and that may affect the credit risk on a financial instrument, including forward looking information to determine a significant increase in credit risk since the initial recognition. Forward looking information includes past events, current conditions and forecasts or future economic conditions (macro-economic data). Credit risk assessment and forward-looking information (including macro-economic factors), includes quantitative and qualitative information based on the Bank’s classification policy: a.Adverse changes in the financial situation, such as a significant increase in debt levels. b.Significant drops in turnover or, in recurring cash flows. c.Significant narrowing of operating margins or recurring income. d.Significant adverse changes in credit risk cost, due to changes in this risk after initial recognition. e.Other changes in the transaction’s credit risk that would impact on conditions being significantly different if the transaction were originated or reissued on the reference date. f.An actual or expected reduction of the integral credit rating of the operation (client’s integral rating) or decrease in the performance score. g.An actual or expected significant decrease in the price or external credit rating of the mail operation, as well as other external market indicators of the credit risk for similar operations with the same expected life. The Bank will classify an operation as Stage 2 when the past-due amounts of an exposure exceed materiality thresholds for 90 or more consecutive days. Expected credit loss measurement The ECL are the probability-weighted estimate of credit losses, i.e. the present value of all cash shortfalls. A cash shortfall is the difference between the cash flows that are due to an entity in accordance with the contract and the cash flows that the entity expects to receive.The Bank considered a multi-factor analysis to perform credit risk analysis. The Bank conducts a corporate evaluation to assess whether objective evidence of impairment exists for loans that are individually significant, and then conducts a separate evaluation of loans that are not individually significant and loans which are significant but for which there is no objective evidence of impairment available under custom monitoring. Credit Risk Governance The Risk Division, our credit analysis and risk management group, is largely independent of our business areas. Risk evaluation teams interact regularly with our clients. For larger transactions, risk teams in our headquarters work directly with clients when evaluating credit risks and preparing credit applications. Various credit approval committees, all of which include Risk Division and Commercial Division personnel, must verify that the appropriate qualitative and quantitative parameters are met by each applicant. Each committee’s powers are defined by our Board of Directors. Santander-Chile’s governance rules establish an Integral Risk Committee. This committee is responsible for revising and following all risks that may affect us, including reputational risk, allowing for an integral risk management. This committee serves as the governing body through which the Board supervises all risk functions. It also evaluates the reasonability of the systems for measurement and control of risks. This Committee includes the Chairman of the Board and five Board members. 155 Table of contents The Board has delegated the duty of credit risk management to the Risk Committee, as well as to the Bank’s risk departments, whose roles are summarized below: •Formulate credit policies by consulting with the business units, meeting requirements of guarantees, credit evaluation, risk rating and submitting reports, documentation and legal procedures in compliance with the regulatory, legal and internal requirements of the Bank. •Establish the structure to approve and renew credit requests. The Bank structures credit risks by assigning limits to the concentration of credit risk in terms of individual debtor, debtor group, industry segment and country. Approval levels are assigned to the corresponding officials of the business unit (commercial, consumer, SMEs) to be exercised by that level of management. In addition, those limits are continually revised. Teams in charge of risk evaluation at the branch level interact on a regular basis with customers; however, for larger credit requests, the risk team from the head office and the Executive Risk Committee works directly with customers to assess credit risks and prepare risk requests. •Limit concentrations of exposure to customers or counterparties in geographic areas or industries (for accounts receivable or loans), and by issuer, credit rating and liquidity. •Develop and maintain the Bank’s credit risk classifications for the purpose of classifying risks according to the degree of exposure to financial loss that is exhibited by the respective financial instruments, with the aim of focusing risk management specifically on the associated risks. •Revise and evaluate credit risk. Management’s risk divisions are largely independent of the Bank’s commercial division and evaluate all credit risks in excess of the specified limits prior to loan approvals for customers or prior to the acquisition of specific investments. Credit renewal and reviews are subject to similar processes. For more detail on credit risk metrics please see: “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Provision for loan losses”, “Item 5. Operating and Financial Review and Prospects—B. Selected Statistical Information- Loan Portfolio”, “Item 5. Operating and Financial Review and Prospects—B. Selected Statistical Information- Credit Ratios”, “Note 8 – Financial Assets at Amortized Costs” and “Note 37-Risk Management-Credit Risk”. 2.Non-financial risks Following the Basel framework, the Bank defines operational risk as the risk of losses arising from defects or failures in its internal processes, people, systems or external events, thus covering risk categories such as fraud, technological, cyber, legal and conduct risk. Operational risk is inherent to all products, activities, processes and systems and is generated in all business and support areas. For this reason, all employees are responsible for managing and controlling the operational risks generated in their sphere of action. The Bank’s goal in terms of operational risk management and control is focused on identifying, evaluating and mitigating sources of risk, regardless of whether they have materialized or not. The analysis of operational risk exposure contributes to the establishment of risk management priorities. The following table summarizes our net losses from operational risks in 2025 compared to 2024. 156 Table of contents As of December 31, % Change 2025 2024 2025/2024 (Ch$ millions) Net losses from operational risks Fraud 34,929 7,633 357.6 % Labor related 3,459 4,969 (30.4) % Client / product related 91 559 (83.7 %) Damage to fixed assets 295 345 (14.5 %) Business continuity / Systems 274 178 53.9 % Processing 2,122 4,950 (57.1 %) Total 41,170 18,634 120.9 % In 2025, the 120.9% increase in operational-related losses was mainly due to higher fraud expenses. The adoption of digital banking and recent regulatory changes have led to a relevant increase in fraud expenses. In 2023 gross fraud related expenses amounted to Ch$ 7,202 million, while in 2024 this increased to Ch$ 33,786 million and Ch$ 41,496 million in 2025. The rapid increase in fraud cases in the first half of 2024 led to improvements in the existing Chilean fraud Law in May 2024 pursuant to Law No. 21,637, which addressed some of the imbalances previously caused by changes enacted in 2020. Among other adjustments, the amendment modified the procedures that users must follow to request the reimbursement of funds associated with claims for unauthorized transactions, requiring a sworn statement and the filing of a complaint with the competent authorities. In addition, the timeframes for such reimbursement were extended. The credit card issuer continues to be responsible for both transactions carried out after the customer reports the fraud as well as for unauthorized transactions. Furthermore, the Bank is also liable for other types of fraud, such as financial scams. With these more stringent requirements in place the Bank recognized lower recoveries from fraud claims in 2025 compared to 2024. In response to the increase in fraud, we have limited the exposure of our clients to credit card fraud through education, insurance coverage, marketing campaigns, daily transfer amount limits, chip technology, improved ATM software, and other technological improvements, Despite these initiatives and investments, the continuous evolution of fraud techniques that affect our clients and subsequently the Bank continues to be a material source of operational loss. Governance The risk management program contemplates that all relevant risk issues must be reported to the Board of Directors, the Integral Risk Committee and the Non-Financial Risk Committee. Risk identification, measurement and assessment model A series of quantitative and qualitative techniques and tools have been defined by the Bank to identify, measure and assess operational risk. The quantitative analysis of this risk assessment is carried out mainly with tools that record and quantify the level of potential losses associated with operational risk events. The qualitative analysis seeks to assess aspects of exposure and hedging (including the control environment). The most important operational risk tools used by Santander Chile are an internal events database, operational risk control self-assessment, analysis of operational risk scenarios, appetite of corporate and local indicators, and internal audit and regulatory recommendations, among others. Operational risk management To accomplish our operational risk objectives, we have established a risk model based on three lines of defense, with the objective of continuously improving and developing our management and control of operational risks. The defense lines consist of: (i) the business and support areas (first line of defense), responsible for managing the risks related to their processes; (ii) the non-financial risk area (second line of defense), in charge of supporting the first line of defense in relation to the fulfillment of its direct responsibilities and; (iii) the internal audit function (third line of defense) responsible for verifying, independently and periodically, the adequacy of the risk identification and management processes and procedures, in accordance with the guidelines established in the Internal Audit Policy and submitting the results of its recommendations for improvement to the Audit Committee. For further information, see “Item 16K. Cybersecurity.” 157 Table of contents Our methodology consists of the evaluation of the risks and controls of a business from a broad perspective and includes a plan to monitor the effectiveness of such controls and the identification of eventual weaknesses. The main objectives of the Bank and its subsidiaries in terms of operational risk management are the following: •Identify, evaluate, mitigate, inform, manage and monitor the operational risk in connection with activities, products, and processes carried out or commercialized by the Bank and its subsidiaries; •Build a strong culture of operational risk management and internal controls, with clearly defined and adequately segregated responsibilities between business and support functions, whether these are internally-developed or outsourced to third parties, and promote an advanced culture of operational risk management; •Generate effective internal reports in connection with issues related to operational risk management, with a clearly defined escalation protocol; and •Control the design and application of effective plans to deal with contingencies that ensure business continuity and losses control. Cyber-security and data security plans The Bank continuously monitors cyber-security risks and has implemented preventative measures to be prepared for any cyber-attack. Likewise, the internal cyber-security model based on best practices and international standards, is periodically evaluated for its maturity level. Through these evaluations, points of improvement have been identified and actions and remediation have been established and incorporated into our cybersecurity plans. For further information, see “Item 16K. Cybersecurity.” Business Continuity Management: Ensuring the realization of critical process during contingencies The Bank has a Business Continuity Management System, which covers the entire organization in order to ensure the execution of the activities that may cause significant negative impacts (operational, reputation, consumer services, legal and operational losses) to the organization. The Non-financial Risk Department, through the Operational Resilience Risk Department (BCM specialized area, as part of the second line of defense), leads the control and implementation of the model and policies defining the roles and responsibilities of each line of defense, where the first line of defense has a main role that involves the identification of their process, the business impact analysis of each risk according to the methodology, the preparation of business continuity plans and strategies to respond to each contingency scenario and ensure the realization of the critical processes, the testing and continuous updating of the information to secure the resources needed (at least annually). The Bank is constantly facing different types of contingencies (mainly natural disasters, pandemics, social movements, protests, among others), which has proven to be effective in order to maintain, social movements, protests, among others), which has proven to be effective in order to maintain and ensure the business continuity of the organization. We are constantly detecting new opportunities to improve the current mitigation actions and contingency plans allowing the critical departments to recover after the events that may occur in the future. Role of Santander Group’s Global Risk Division: Operational Risk In matters regarding operational risk, Santander Global Risk Department’s role is to define certain global policies, guidelines and procedures regarding operational risk.. The Risk Control Committee reviews relevant matters from the different Santander units that may impact operational risk. 3.Market Risks This section describes the market risks that we are exposed to, the tools and methodology used to control these risks, the portfolios over which these market risk methods were applied and quantitative disclosure that demonstrate the level of exposure to market risk that we are assuming. This section also discloses the derivative instruments that we use to hedge exposures and offer to our clients. Market risk is the risk of losses due to unexpected changes in interest rates, foreign exchange rates, inflation rates and other rates or prices. We are exposed to market risk mainly as a result of the following activities: •trading in financial instruments, which exposes us to interest rate and foreign exchange rate risk; 158 Table of contents •engaging in banking activities, which subjects us to interest rate risk, since a change in interest rates affected gross interest income, gross interest expense and customer behavior; •engaging in banking activities, which exposes us to inflation rate risk, since a change in expected inflation affects gross interest income, gross interest expense and customer behavior; •trading in the local equity market, which subjects us to potential losses caused by fluctuations of the stock market; and •investing in assets whose returns, or accounts are denominated in currencies other than the Chilean peso, which subjects us to foreign exchange risk between the Chilean peso and such other currencies. The main decisions that relate to market risk for the Bank and the limits regarding market risk are made in the Asset and Liability Committee. The measurement and oversight of market risks is performed by the Market Risk Department. Santander-Chile’s governance rules have established the Asset and Liability Committee to monitor and control market risks. Role of Santander Group’s Global Risk Division: Market Risk In matters regarding Market Risk, the role of Santander Spain’s Global Risk Department is to define certain global policies, guidelines and procedures regarding market risk. The information produced by our local Market Risk Department is standardized for the whole group in order to facilitate a consolidation of risks being taken on a global basis. They review daily the consumption of limits and provide valuable input on the evolution of markets, especially regarding the Eurozone. 4.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$39,727.96 as of December 31, 2025, Ch$38,416.69 as of December 31, 2024, and Ch$36,789.36 as of December 31, 2023. 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. Inflation measured as the annual variation of the UF was 3.4% in 2025, 4.4% in 2024, and 4.8% in 2023. 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 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: •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. •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 159 Table of contents 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$236,523 in 2025, a loss of Ch$535,558 million in 2024, and a loss of Ch$1,147,193 million in 2023. 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$7,403,454 million in 2025, Ch$7,518,560 million in 2024 and, Ch$6,875,280 million in 2023. Therefore, our sensitivity to a 100-basis point shift in UF inflation considering our average gap in 2025 would be approximately Ch$74 billion. The financial impact of the gap between our interest earning assets and liabilities denominated in UFs including hedges was as follows: As of December 31, % Change 2025 2024 2023 2025/2024 2024/2023 (in millions of Ch$) Impact of inflation on net interest income Results from UF GAP(1) 253,849 323,751 321,698 (21.6 %) 0.6 % Annual UF inflation 3.4 % 4.4 % 4.8 % (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. The lower result from UF inflation in 2025 when compared to 2024 was mainly due to the lower UF inflation in 2025 compared to 2024. 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. See “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Interest 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 usually 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 5. Operating and Financial Review and Prospects—A. Operating Results—Impact of Inflation—Peso-denominated assets and liabilities.” 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 160 Table of contents of such demand deposits and average shareholder’s equity to average interest-earning assets was 31.3%, 30.7% and 29.0% for the years ended December 31, 2025, 2024 and 2023, respectively.

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 9.4% in 2025, depreciated 13.7% in 2024 and depreciated 2.9% in 2023. 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, 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. As of December 31, 2025, this was equal to U.S.$350 million. This limit in various other currencies is as follows: 162 Table of contents Currency Limit (in millions of U.S.$) U.S. dollars 350 Euros 110 Yen 27 British pound 20 Mexican peso 30 Brazilian real 30 Colombian peso 30 Peruvian sol 20 Other European currencies 30 Other Latin American currencies 30 Other currencies 47.5 Total Limit 350 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.$1.04 million in 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 average non-interest bearing demand deposits represented 40.6% of our average total liabilities and shareholders’ equity in 2025. As of December 31, 2025, the Bank’s top 20 time deposits represented 20.0% of total time deposits, or 4.8% 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 and debt instruments 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 163 Table of contents 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 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 December 31, 2025, and 2024, the breakdown of the Bank’s liquid assets by levels was the following: December 31, 2025 December 31, 2024 (Ch$ million) Balance as of: Cash and cash equivalent 1,904,994 2,416,812 Level 1 liquid assets(1) 6,227,856 7,241,318 Level 2 liquid assets(2) 3,163 4,517 Total liquid assets 8,136,014 9,662,647 (1)Includes available balances held in the Central Bank of Chile, financial instruments issued by the Chilean Treasury or Central Bank and other financial instruments issued or guaranteed by States, multilateral development banks or foreign central banks that have a first-class rating, in accordance with international rating agencies. 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. December 31, 2025 December 31, 2024 (Ch$ million) (Ch$ million) Average balance as of: Cash and cash equivalent 1,828,528 1,732,701 Level 1 liquid assets(1) 6,476,798 6,236,963 Level 2 liquid assets(2) 3,660 5,217 Total liquid assets 8,308,986 7,974,881 (1)Includes available balances held in the Central Bank of Chile, financial instruments issued by the Chilean Treasury or Central Bank and other financial instruments issued or guaranteed by States, multilateral development banks or foreign central banks that have a first class rating, in accordance with international rating agencies.

(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: •Liquidity coverage ratio (LCR), which measures the percentage of Liquid Assets over Net Cash Outflows. This liquidity ratio per Chilean regulations cannot be lower than 100%. As of December 31, 2025, this indicator for Banco Santander Chile was 187.7% •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 164 Table of contents reach 100% by 2026. As of December 31, 2025, this indicator for Banco Santander Chile was 115.1% in compliance with the local regulatory limit. •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 December 31, 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 9% 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: •trading portfolio; •local financial management portfolio; and •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 2025, 2024 and 2023 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. 165 Table of contents 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: •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; •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; •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; •The VaR is calculated at the close of business, but trading positions may change substantially in the course of the trading day; •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 •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. 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. 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 December 31, 2025 was U.S.$1.67 million, which is below the total limit. The high, low, and average levels for each component and each year below were as follows: Consolidated 2025 2024 2023 (in millions of U.S.$) VaR High 2.87 4.06 6.23 Low 1.05 1.47 2.73 Average 1.67 2.40 4.41 Fixed-income investments High 2.83 3.33 5.78 Low 0.96 1.41 2.75 Average 1.36 2.23 4.20 Variable-income investments High — — — 166 Table of contents Low — — — Average — — — Foreign currency investments High 2.62 3.93 4.82 Low 0.16 0.18 0.17 Average 1.04 1.55 1.14 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 nominal yield curve of 100bp in 2025, 2024 and 2023 (57 basis points for real rates (UF)). 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. In addition, the sensitivity simulation methodology should be interpreted taking into consideration the following limitations: •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. •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. •The model does not take into account the sensitivity of volumes which results from interest rate changes. •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.

According to FMC 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 Board set this limit at 35% of the Bank’s regulatory capital. Nonetheless, the FMC can lower limits at their discretion as part of its supervisory authority over the risk management of the Bank.

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. •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. •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. •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 contracts with CSA and breakdown the fair value of our derivative portfolio by collateral threshold requirements for 2025 and 2024.

We enter into derivative contracts with some clients who seek hedging instruments. However, substantially all of our derivatives are not actually used for speculative purposes or trading. 169 Table of contents As of December 31, 2025, the Bank held the following portfolios of financial assets and liabilities derivative contracts for trading at fair value through profit and loss: As of December 31, 2025 Notional amount Demand Up to 1 month Between 1 and 3 months Between 3 and 12 months Between 1 and 3 years Between 3 and 5 years More than 5 years Total Fair value Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Assets Currency forward — 25,231,549 17,959,495 27,913,502 6,971,335 2,517,760 1,663,646 82,257,287 2,055,569 Interest rate swaps — 13,947,595 29,006,667 30,995,890 20,723,603 16,894,592 31,276,092 142,844,439 1,332,806 Cross currency swaps — 1,434,261 5,123,374 13,944,592 20,763,957 15,684,701 24,426,683 81,377,568 7,489,381 Call currency options — 22,061 23,401 56,923 — — — 102,385 1,039 Put currency options — 39,178 3,415 5,239 — — — 47,832 982 Total — 40,674,644 52,116,352 72,916,146 48,458,895 35,097,053 57,366,421 306,629,511 10,879,777 As of December 31, 2025 Notional amount On Demand Up to 1 month Between 1 and 3 months Between 3 and 12 months Between 1 and 3 years Between 3 and 5 years More than 5 years Total Fair value Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Liabilities Currency forward — 23,750,958 20,824,030 27,092,792 5,136,179 1,136,565 700,706 78,641,230 2,173,004 Interest rate swaps — 16,930,774 20,745,410 35,069,132 21,274,251 15,793,974 29,527,648 139,341,189 1,134,840 Cross currency swaps — 1,172,436 4,049,436 10,566,265 19,536,479 12,329,038 22,921,210 70,574,864 7,276,583 Call currency options — 27,767 47,768 25,958 — — — 101,493 491 Put currency options — 56,787 73,951 73,075 — — — 203,813 2,390 Total — 41,938,722 45,740,595 72,827,222 45,946,909 29,259,577 53,149,564 288,862,589 10,587,308 As of December 31, 2024, the Bank holds the following the Bank holds the following portfolios of financial assets and liabilities derivative contracts for trading at fair value through profit and loss: As of December 31, 2024 Notional amount Demand Up to 1 month Between 1 and 3 months Between 3 and 12 months Between 1 and 3 years Between 3 and 5 years More than 5 years Total Fair value Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Assets Currency forward — 14,227,181 9,262,636 13,988,163 5,818,091 576,456 993,915 44,866,442 1,038,292 Interest rate swaps — 15,353,818 15,394,905 16,392,696 21,541,572 9,219,884 17,265,959 95,168,834 1,907,001 Cross currency swaps — 1,826,508 3,315,310 11,052,105 27,159,964 13,026,424 23,665,080 80,045,391 9,356,353 Call currency options — 42,802 198,509 117,175 8,921 — — 367,407 6,618 Put currency options — 71,468 253,669 37,950 — — — 363,087 1,506 Total — 31,521,777 28,425,029 41,588,089 54,528,548 22,822,764 41,924,954 220,811,161 12,309,770 As of December 31, 2024 Notional amount On Demand Up to 1 month Between 1 and 3 months Between 3 and 12 months Between 1 and 3 years Between 3 and 5 years More than 5 years Total Fair value Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Liabilities Currency forward — 11,564,755 9,439,120 14,191,034 10,403,238 1,680,685 1,598,835 48,877,667 1,151,921 Interest rate swaps — 16,536,773 12,505,389 16,690,413 18,464,156 9,887,330 16,615,159 90,699,220 1,565,539 Cross currency swaps — 1,325,472 2,195,962 8,993,722 19,955,223 11,501,296 19,704,815 63,676,490 9,430,069 Call currency options — 81,510 143,946 58,826 — — — 284,282 5,530 170 Table of contents Put currency options — 248,733 106,519 138,505 8,921 — — 502,678 1,965 Total — 29,757,243 24,390,936 40,072,500 48,831,538 23,069,311 37,918,809 204,040,337 12,155,024 We also use derivatives to hedge our exposure to foreign exchange, interest rate and inflation risks. The Bank uses derivatives, mainly Ch$/UF swaps, in order to cover its exposure to inflation due to a higher amount of assets linked to inflation as compared to liabilities. Such derivatives are accounted for as cash flow hedges. Our Financial Management Division usually seeks to maintain liabilities with an average duration that is shorter than that of our assets, including through the use of derivatives, in order to hedge against sudden or rapid falls in the inflation rate, which in general triggers a reduction in short-term rates. To maintain this position, the Bank enters into interest rate swaps that are accounted for as fair value hedges. As of December 31, 2025 and 2024 the Bank holds the following portfolio of derivative instruments for hedging purposes: As of December 31, 2025 Notional amount Fair value Demand Up to 1 month Between 1 and 3 months Between 3 and 12 months Between 1 and 3 years Between 3 and 5 years More than 5 years Total Assets Liabilities Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Fair value hedge derivatives Interest rate swaps — — — 175,000 2,075,449 752,638 180,138 3,183,225 580 103,009 Cross currency swaps — 208,960 836,741 3,432,758 2,185,078 1,142,547 2,069,995 9,876,079 202,632 421,620 Subtotal — 208,960 836,741 3,607,758 4,260,527 1,895,185 2,250,133 13,059,304 203,212 524,629 Currency forwards — 272,306 311,863 1,076,376 — — — 1,660,545 5,843 20,706 Cross currency swaps — 589,136 1,673,048 3,546,146 3,814,876 2,844,561 553,938 13,021,705 52,137 367,381 Subtotal — 861,442 1,984,911 4,622,522 3,814,876 2,844,561 553,938 14,682,250 57,980 388,087 Total — 1,070,402 2,821,652 8,230,280 8,075,403 4,739,746 2,804,071 27,741,554 261,192 912,716 As of December 31, 2024 Notional amount Fair value Demand Up to 1 month Between 1 and 3 months Between 3 and 12 months Between 1 and 3 years Between 3 and 5 years More than 5 years Total Assets Liabilities Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Ch$mn Fair value hedge derivatives Interest rate swaps — — — 2,047,050 1,153,300 543,000 397,640 4,140,990 40,062 78,329 Cross currency swaps — 841,009 224,877 2,093,135 3,127,813 1,177,983 1,436,626 8,901,443 462,924 243,723 Subtotal — 841,009 224,877 4,140,185 4,281,113 1,720,983 1,834,266 13,042,433 502,986 322,052 Cash flow hedge derivatives Currency forwards — 149,115 160,050 1,861,085 — — — 2,170,250 65,196 — Cross currency swaps — 889,661 1,989,477 3,491,191 7,437,766 528,886 1,153,235 15,490,216 275,446 576,342 Subtotal — 1,038,776 2,149,527 5,352,276 7,437,766 528,886 1,153,235 17,660,466 340,642 576,342 Total — 1,879,785 2,374,404 9,492,461 11,718,879 2,249,869 2,987,501 30,702,899 843,628 898,394

A.[Reserved] B.Capitalization and Indebtedness Not applicable. C.Reasons for the Offer and Use of Proceeds Not applicable. D.Risk Factors You should carefully consider the following risk factors, which should be read in conjunction with all the other information presented in this Annual Report. 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. The following risk factors have been grouped as follows: (a)Risk Factors in respect of Santander-Chile; (b)Risk Factors in respect of Chile; (c)Risk Factors in respect of our Controlling Shareholder and our ADSs; and (d)General Risk Factors. The risk factors in respect of Santander-Chile are presented in the following subcategories depending on their nature: (a)Macro-economic Risks; (b)Competitive Risks; (c)Operational Risks; (d)Financial Risks; and (e)Legal and Regulatory Risks. 1 Table of contents Summary of Key Risks Our business is subject to numerous risks and uncertainties, discussed in more detail below. These risks include, among others, the following key risks: •The growth rate of our loan portfolio may be affected by economic turmoil, which could also lead to a contraction in our loan portfolio. •Inflation, government efforts to control inflation, and changes in interest rates may hinder the growth of the Chilean economy and could have an adverse effect on us. •Geopolitical conflicts and related uncertainties, such as the continuance or escalation of the war in Ukraine and the uncertainties following the ceasefire agreement in the Middle East, could materially affect our financial position and increase our operational risk. •We are vulnerable to disruptions and volatility in the global financial markets. •Our operations and results may be negatively affected by earthquakes due to the location of Chile in a highly seismic area. •Climate change can create transition risks, physical risks, and other risks that could adversely affect us. •Increased competition, including from non-traditional providers of banking services such as financial technology providers, and industry consolidation may adversely affect our results of operations. •Our ability to maintain our competitive position depends, in part, on the success of new products and services we offer our customers. •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. •Failure to successfully implement and continue to improve our risk management policies, procedures and methods, including our credit risk management system, could materially and adversely affect us, and we may be exposed to unidentified or unanticipated risks. •We rely on models for many of our decisions. Their inaccurate or incorrect use could have a material adverse effect on us. •Our loan and investment portfolios are subject to risk of prepayment, which could have a material adverse effect on us. •Risks relating to cybersecurity, data collection, processing and storage systems and security are inherent in our business. •Disclosure controls and procedures over financial and non-financial reporting may not prevent or detect all errors or acts of fraud. •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. •Our financial results are constantly exposed to market risk. We are subject to fluctuations in inflation, interest rates and other market variables, which may materially and adversely affect us and our profitability. •We are subject to counterparty risk in our banking business. •Liquidity and funding risks are inherent in our business and could have a material adverse effect on our results, our costs of funds and our credit ratings. •We are subject to regulatory capital and 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. •We are subject to extensive regulatory risk, or the risk of not being able to meet all of the applicable regulatory requirements and guidelines. •Changes to the pension fund system may affect our funding mix. •We may not be able to detect or prevent money laundering and other financial crime activities fully or on a timely basis, which could expose us to additional liability and could have a material adverse effect on us. •We are exposed to risk of loss from legal and regulatory proceedings. •Political, legal, regulatory and economic uncertainty arising from social unrest and the resulting social reforms, as well as the potential enactment of a new constitution could adversely impact the Bank’s business. •Our growth, asset quality and profitability may be adversely affected by volatile macroeconomic and political conditions in Chile. •Currency fluctuations could adversely affect our financial condition and results of operations and the value of our securities. •Our controlling shareholder has a great deal of influence over our business and its interests could conflict with yours. •Our status as a controlled company and a foreign private issuer exempts us from certain of the corporate governance standards of the New York Stock Exchange (“NYSE”), limiting the protections afforded to investors. 2 Table of contents •As a holder of ADSs you will have different shareholders’ rights than in the United States and certain other jurisdictions. Holders of ADSs may find it difficult to exercise voting rights at our shareholders’ meetings. RISK FACTORS IN RESPECT OF SANTANDER-CHILE Macro-Economic Risks 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 acceptable financial terms, if at all. If capital markets financing becomes unavailable excessively expensive, we may be forced to raise the rates we pay on deposits to attract more customers and may be unable to maintain certain liability maturities. Any such adverse impact in capital markets funding availability or costs or in deposit rates could have a material adverse effect on our interest margins and liquidity. In particular, we face, among others, the following risks related to economic downturns and volatile conditions: •A reduction in demand for our products and services. •An increase or change in 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. •An inability of our customers to timely or fully comply with their existing obligations. Macroeconomic shocks may negatively impact the income of our retail and corporate customers and may adversely affect the recoverability of our loans, resulting in increased loan losses. •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. •The value and liquidity of the portfolio of investment securities that we hold may be adversely affected. In particular, in 2025 Chile experienced a moderate increase in economic activity as lower interest rates, both in Chile and globally, drove growth. In 2025, Chile’s economy is expected to grow 2.4% compared to 2.6% in 2024 and 0.5% in 2023. In 2025, inflation based on the Chilean consumer price index, was 3.4% compared to 4.5% in 2024 and 3.9% in 2023. The Central Bank's reference rate, which is used to set monetary policy, closed 2025 at 4.50% compared to 5.00% in 2024 and 8.25% in 2023. Currently, the Central Bank expects GDP to increase in a range between 2%-3% in 2026. 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 growth rate of our loan portfolio may be affected by economic turmoil, which could also lead to a contraction in our loan portfolio. There can be no assurance that our loan portfolio will continue to grow at similar rates to historical growth rates. A reversal of the rate of growth of the Chilean economy, a slowdown in the growth of customer demand, an increase in market competition or changes in governmental regulations could adversely affect the rate of growth of our loan portfolio 3 Table of contents and our risk index and, accordingly, increase our required allowances for loan losses. Economic turmoil could materially adversely affect the liquidity, businesses and financial condition of our customers as well as lead to a general decline in consumer spending and a rise in unemployment. All this could in turn lead to decreased demand for borrowings in general. Climate change can create transition risks, physical risks, and other risks that could adversely affect us. There is an increasing focus over the risks of climate change and related environmental sustainability matters. Climate change may imply two primary drivers of financial risk that could adversely affect us: •Transition risks associated with the move to a low-carbon economy, both at idiosyncratic and systemic levels, such as through policy, regulatory and technological changes and business consumer preferences, which could increase our exposure and impact our strategies. •Physical risks related to discrete events, such as flooding and wildfires, and extreme weather impacts and longer term shifts in climate patterns, such as extreme heat, sea level rise and more frequent and prolonged drought, which could result in financial losses that could impair asset values and the creditworthiness of our customers. Such events could disrupt our operations or those of our customers or third parties on which we rely and do business with, including through direct damage to assets and indirect impacts from supply chain disruption and market volatility. These primary drivers could materialize, among others, in the following financial risks: •Credit risks: Physical climate change could lower corporate revenues, increase operating costs and lead to increased credit exposure. Severe weather could also affect the value of collateral. Additionally, companies with business models not aligned with the transition to a low-carbon economy may face a higher risk of reduced corporate earnings and business disruption due to new regulations or market shifts. •Market risks: Market changes in the most carbon-intensive sectors could affect energy and commodity prices, corporate bonds, equities and certain derivatives contracts. Increasing frequency of severe weather events could affect macroeconomic conditions, weakening fundamental factors such as economic growth, employment and inflation and lead to higher volatility. •Liquidity risks: Companies could face liquidity risks derived from cash outflows to improve their reputation in the market or solve climate-related problems. Extreme weather events could also affect the value of our high-quality liquid assets or cause sovereign debt to rise limiting our access to capital markets. •Operational risks: Severe weather events could directly damage assets and impact business continuity, both of our customers and our own. Climate-related financial risks could also cause operational risk losses from litigation if, for example, we are perceived to misrepresent sustainability-related practices, achievements, metrics goals or targets. •Regulatory compliance risks: Increased regulatory compliance risk may result from the increasing pace, breadth and depth of regulatory expectations requiring implementation in short timeframes across multiple jurisdictions and from changes in public policy, laws and regulations in connection with climate change and related environmental sustainability matters. •Reputational risks: Our reputation and client relationships may be damaged as a result of our practices, disclosures and decisions related to climate change and the environment, or to the practices or involvement of our clients, vendors or suppliers in certain industries or projects being associated with causing or exacerbating climate change. Furthermore, parties who may suffer losses from the effects of climate change may seek compensation from those they hold responsible such as state entities, regulators, investors and lenders. We could face conduct risks derived from misrepresentations in our sustainability-related disclosures, including our practices, achievements, metrics, 4 Table of contents goals and targets or the sustainability characteristics of our products or of our customers, investors or other stakeholders (greenwashing). •Strategic risks: Our strategy could be affected if we fail to achieve our net-zero or other targets, including those related to the activities that we finance and those concerning our own operations. As climate risk is interconnected with all key risk types, we have developed and continue to enhance processes to embed climate risk considerations into our core processes and risk management cycle; however, because the timing and severity of climate change may not be predictable and is rapidly evolving, our risk management strategies may not be effective in mitigating climate risk exposure. Additionally, we may become subject to new or heightened regulatory requirements relating to climate change, which may result in increased regulatory, compliance or other costs. As the risks, perspective and focus of regulators, shareholders, employees, and other stakeholders regarding climate change are evolving rapidly, it can be difficult to assess the ultimate impact on us of climate change-related risks, compliance risks, and uncertainties. We periodically disclose information such as emissions and other climate-related performance data, statistics, metrics and/or targets. If we lack robust and high-quality climate-related procedures, controls and data, we may not be able to disclose reliable climate-related information. In addition, because the climate-related information is based on current expectations and future estimates about Santander Chile’s and third-parties’ operations and businesses and addresses matters that are uncertain to varying degrees, we may not be able to meet our estimates and targets or we may not be able to achieve them within the timelines we announce. Actual or perceived shortcomings with respect to these emissions and other climate-related initiatives and reporting could result in litigation or regulatory enforcement and impact our ability to hire and retain employees, increase our customer base, and attract and retain certain types of investors. The exposures in the sectors potentially most affected by climate factors (according to market consensus and the Bank’s materiality analysis) mainly correspond to corporate and investment banking portfolios. The management of these clients, in these sectors includes, where appropriate and permissible, the consideration of climate aspects in their initial analysis, in the granting of credit, and in the preparation and review of their credit ratings. These ratings influence the parameters that are used to calculate their credit losses (typically via probability of default, PD). Accordingly, when climate factors are relevant, they impact, along with other elements of analysis, on the credit loss calculations that support capital and provisions. We have recently participated in regulatory climate stress exercises, which indicate that our current overall coverage of potential losses is adequate over the maturity horizons of our portfolios. According to the FMC’s loan classification system (See Note 37—Risk Management—Analysis of risk concentration), sectors with very high climate risk (oil and gas and mining and metals), mainly due to transition risk, accounted for 1.0% of the total loan portfolio, mainly direct exposure to copper production. For these and other sectors we have decarbonization objectives and action plans. Initiatives and business practices of financial institutions with respect to climate matters and other matters of public policy, including environmental, social and governance (ESG) matters, have recently become the subject of significant scrutiny by regulatory agencies and government officials. Views on sustainability or ESG practices, particularly those related to climate issues, have become ideological issues and both opponents and proponents of various ESG-related matters have increasingly engaged in a range of activism to advocate their positions. In particular, there are a growing number of initiatives in certain jurisdictions aimed at discouraging or limiting the consideration of ESG factors by financial institutions that may conflict with certain regulatory requirements to which we are subject or the expectations of our clients, shareholders and other stakeholders. Such differing, sometimes conflicting, views and regulations on sustainability and ESG-related matters increase the risk that certain of our actions, or lack of action, on such matters will be perceived negatively. Additionally, the overall expectations of regulators and our clients, shareholders and other stakeholders in certain jurisdictions, particularly in Europe, with respect to certain of these issues may differ significantly from those in other jurisdictions, such as the United States. Furthermore, our relationships or ability to transact with clients and customers, and with governmental or regulatory bodies in certain jurisdictions could be adversely affected if our decisions with respect to doing business with companies in certain sensitive industries are perceived to harm those companies, result in violations of law and breaches of fiduciary duty or to align with particular ideological, political or social views. We are also exposed to associated risks of non-compliance with relevant legal requirements, including fines, penalties, litigation, regulatory sanctions, difficulties in obtaining governmental approvals, restrictions on our business activities or reputational damage, any of which could be material. Additionally, our participation in, or association with, certain groups or initiatives 5 Table of contents and our business practices or positions with respect to matters of public policy, including ESG matters, could be criticized by activists, governmental authorities and our clients, shareholders and other stakeholders. Any of the conditions described above, or our failure to identify other climate-related risks, could have a material adverse effect on our business, financial condition and results of operations. The outbreak of public health emergencies materially impacted, and may in the future materially impact, our financial condition, liquidity and results of operations. The outbreak of public health emergencies may force countries to adopt measures, similar to those adopted in response to the Covid-19 pandemic, that restrict economic activity, may deteriorate the macroeconomic environment and may adversely impact our business and results of operations, including, among others (i) decreased demand for our products and services; (ii) further material impairment of our loans and other assets including goodwill; (iii) decline in the value of collateral; (iv) constraints on our liquidity due to market conditions, exchange rates and customer withdrawal of deposits and continued draws on lines of credit; (v) downgrades of our credit ratings; and (vi) operational disruptions, technology infrastructure failures, increased cybersecurity risks or governmental restrictions affecting our operations. Any such events could materially and adversely affect our business, financial condition, liquidity and results of operations. Competitive Risks Increased competition, including from non-traditional providers of banking services such as financial technology providers, and industry consolidation may adversely affect our results of operations. We face substantial competition in all parts of our business, including in payments, in originating loans and in attracting deposits. The competition in originating loans comes principally from other domestic and foreign banks, mortgage banking companies, consumer finance companies, insurance companies and other lenders and purchasers of loans. The Chilean market for financial services is highly competitive. We compete with other private sector Chilean and non-Chilean banks, with Banco del Estado de Chile, the principal government-owned sector bank, with department stores, private lenders (principally department stores and auto-lenders) and with credit unions and cooperatives that make consumer loans and sell other financial products to a large portion of the Chilean population. In addition, we face competition from non-bank finance competitors, such as leasing and factoring companies, security brokers, mutual fund administrators, pension fund management companies and insurance companies. The lower to middle-income segments of the Chilean population and the small- and mid-sized corporate segments have become the target markets of several banks and competition in these segments may increase. In addition, there has been a trend towards consolidation in the Chilean banking industry in recent years, which has created larger banks with which we must now compete. There can be no assurance that this increased competition will not adversely affect our growth prospects, and therefore our operations. Non-traditional providers of banking services, such as fintechs, Internet-based e-commerce providers, mobile telephone companies and Internet search engines may offer and/or increase their offerings of financial products and services directly to customers. These non-traditional providers of banking services currently have an advantage over traditional providers because they are not subject to banking regulation. Several of these competitors may have long operating histories, large customer bases, strong brand recognition and significant financial, marketing and other resources. They may adopt more aggressive pricing and rates and devote more resources to technology, infrastructure and marketing. For example, in December 2025, the Central Bank of Chile approved the operational regulations for a new payment clearinghouse for low value transactions, which is expected to commence operations subject to further regulatory approvals. The entry of new payment infrastructures and participants may increase competition especially in the checking account and debit card markets, alter transaction flows, and/or require additional technological adaptations. As the Chilean payments ecosystem continues to evolve, new clearing participants may influence transaction routing, fee structures, or require incremental technological adaptations. While we continuously monitor regulatory and market developments and adjust our systems and strategy accordingly, the extent to which this new infrastructure could affect our revenues, operating costs, or operating performance cannot presently be quantified. New competitors may enter the market or existing competitors may adjust their services with unique product or service offerings or approaches to providing banking services. If we are unable to successfully compete with current and new competitors, or if we are unable to anticipate and adapt our offerings to changing banking industry trends, including 6 Table of contents technological changes, our business may be adversely affected. In addition, our failure to effectively anticipate or adapt to emerging technologies or changes in customer behavior, including among younger customers, could delay or prevent our access to new digital-based markets, which would in turn have an adverse effect on our competitive position and business. Furthermore, the widespread adoption of new technologies, including distributed ledger, artificial intelligence (“AI”) and/or biometrics, to provide services such as cryptocurrencies and payments, could require substantial expenditures to modify or adapt our existing products and services as we continue to grow our Internet and mobile banking capabilities and could entail new direct risks (including financial and non-financial risks) and indirect risks related to loss of business opportunities. Our customers may choose to conduct business or offer products in areas that may be considered speculative or risky. Such new technologies and mobile banking platforms in recent years could negatively impact the value of our investments in bank premises, equipment and personnel for our branch network. The persistence or acceleration of this shift in demand towards Internet and mobile banking may necessitate further changes to our retail distribution strategy, which may include closing and/or selling certain branches (as we have been doing in recent years) and restructuring our remaining branches and work force. These actions could lead to losses on these assets and may lead to increased expenditures to renovate, reconfigure or close a number of our remaining branches or to otherwise reform our retail distribution channel. Furthermore, our failure to implement such changes to our distribution strategy swiftly and effectively could have an adverse effect our competitive position. In particular, we face the challenge to compete in an ecosystem where the relationship with the consumer is based on access to digital data. This access is increasingly dominated by digital platforms and fintechs who are already eroding our results in very relevant markets such as payments. This privileged access to data can be used as a leverage to compete with us in other adjacent markets and may reduce our operations and margins in core businesses such as lending or wealth management. The alliances that our competitors are starting to build with large technology firms can make it more difficult for us to successfully compete with them and could adversely affect us. In January 2023 the law on Fintech and Open Finance System was published and in July 2024, the FMC published the regulations governing the Open Finance System (or the “SFA” pursuant to its Spanish acronym) under the Fintech Law, which is expected to enter into force in July 2026. The SFA regulations establish that institutions subject to financial regulation (such as banks, payment card issuers and acquirers, insurance companies, fund managers, savings and credit cooperatives supervised by the FMC) must become a part of the SFA and facilitate the sharing of user data with other institutions that are a part of the SFA, after users have given their consent. In addition, the FMC established certain rules for institutions that voluntarily decide to register with the SFA and offer financial services to users. This mandatory data sharing will be done through application programming interfaces (“APIs”) that reporting entities will have to activate on websites set up for this purpose. The regulations published by the FMC do not cover the technical requirements and the design of the cost compensation model for the SFA, which are still being drafted. To address these issues, the FMC established a working group with various affected industries that will be working on the proposals throughout 2025. There is regulatory uncertainty in relation to the final content of such regulations, and whether these will contemplate adequate regulatory symmetry between all affected parties. The implementation period of the SFA will be gradual and will vary depending on the type of institution. The first stage of the implementation has a 24-month phase-in period, which will be used by each of the participating institutions to adapt their systems. During this period, the FMC will also develop the technical manuals containing the relevant specifications for the operational implementation of the SFA. In November 2025, the FMC launched a new public consultation proposing amendments to the SFA framework. For banks and payment card issuers, the regulations provide an implementation schedule that begins with the phased delivery of information to be exchanged through the SFA: (i) APIs containing general terms and conditions and awareness channels for the products and services offered by the reporting entities (within the first 6 months); (ii) APIs containing user information (onboarding, financial position, transaction records and current products) that banks and payment card issuers must share with other participants in the SFA (within the first 18 months); and (iii) APIs containing payment initiation information (within the first 18 months). The consultation sought to incorporate feedback from banks, fintech companies, insurers, cooperatives, and other market participants. The main objectives of the proposed changes are to make its implementation more gradual, improve operational feasibility, and ensure an adequate balance between innovation, competition, and financial stability. The key proposed adjustments include: extension of effectiveness deadlines and a more realistic rollout schedule, introduction of intermediate milestones and a pilot or testing phase before full enforcement, simplification of participation requirements for certain types of entities, refinements to user consent management, data traceability, and interoperability rules, adjustments to governance and operational responsibilities among SFA participants, and further development of technical requirements for APIs and testing environments. 7 Table of contents Despite progress, some regulatory uncertainty remains, particularly regarding: the final content of the technical standards, the structure and fairness of the cost compensation model, the degree of regulatory symmetry between traditional regulated institutions and new fintech entrants, and the operational burden and liability allocation among participants. The FMC has acknowledged that the success of the SFA depends heavily on robust technical standards and fair economic incentives. Therefore, detailed API specifications, cybersecurity standards, performance metrics, and interoperability rules are still under development. A cost compensation model, to define whether and how data providers may be compensated by data users, has not yet been finalized. To address these issues, the FMC established a working group with representatives from affected industries which is currently engaged in ongoing discussions. The group’s work is expected to feed into future technical annexes or complementary regulations. Implementation of the SFA regulations may reduce barriers to entry and increase competition in our industry, which could reduce our market share or require us to reduce prices for the services we provide, which could have a material adverse effect on our results of operations, financial condition and prospects. Increasing competition could also require that we increase our rates offered on deposits or lower the rates we charge on loans, which could also have a material adverse effect on us, including our profitability. It may also negatively affect our business results and prospects by, among other things, limiting our ability to increase our customer base and expand our operations and increasing competition for investment opportunities. If our customer service levels were perceived by the market to be materially below those of our competitor financial institutions, we could lose existing and potential business. If we are not successful in retaining and strengthening customer relationships, we may lose market share, incur losses on some or all of our activities or fail to attract new deposits or retain existing deposits, which could have a material adverse effect on our operating results, financial condition and prospects. Our ability to maintain our competitive position depends, in part, on the success of new products and services we offer our customers and on our ability to offer products and services that meet the customers’ needs during the whole life cycle of the products or services. Our failure to manage various risks we face as we develop new products and services that could have a material adverse effect on us. The success of our operations and our profitability depends, in part, on the success of new products and services we offer our customers and our ability to offer products and services that meet their needs during their entire life cycle. However, our customers’ needs, or desires may change over time, and such changes may render our products and services obsolete, outdated or unattractive and we may not be able to develop new products that meet our customers’ changing needs. Our success is also dependent on our ability to anticipate and leverage new and existing technologies that may have an impact on products and services in the banking industry. Technological changes may further intensify and complicate the competitive landscape and influence customer behavior. If we cannot respond in a timely fashion to the changing needs of our customers, including as a result of an aging population, we may lose existing or potential customers, which could in turn materially and adversely affect us. In addition, the cost of developing products is likely to affect our results of operations. We face the challenge of simplifying the range of our products and services, and, at the same time, being able to satisfy the needs of our clients by offering new products and services. The development of these new products and services exposes us to new and potentially increasingly complex risks, such as the conduct risk in the relationship with customers, and development expenses. Our employees and our risk management systems, as well as our experience and that of our partners may not be sufficient to enable us to properly manage such risks. Any or all of these factors, individually or collectively, could have a material adverse effect on us. Our strong position in the credit card market is significantly dependent on our co-branding agreement with LATAM Airlines, which was renewed in August 2025 for a five-year term. Once the current term expires, there can be no assurance that the agreement will be renewed, extended, or maintained on terms comparable to those currently in effect, or at all. A failure to renew, or renewal on less favorable terms, could materially reduce the attractiveness of our credit card offering, result in the loss of customers and transaction activity, which could in turn materially and adversely affect our results of operations, competitive position, and financial condition in this business. In addition, in response to the evolving regulatory environment affecting interchange fees, we implemented adjustments to our loyalty program under the Santander Rewards framework to encourage broader use of our banking products beyond credit cards. These changes may not achieve their intended objectives and could lead to customer 8 Table of contents dissatisfaction, reduced engagement, or lower credit card usage. Any such outcomes could negatively affect customer relationships, competitive positioning, and revenue generation in our credit card segment. While we have successfully increased our customer service levels in recent years, should these levels ever be perceived by the market to be materially below those of our competitor financial institutions, we could lose existing and potential new business. If we are not successful in retaining and strengthening customer relationships, we may lose market share, incur losses on some or all of our activities or fail to attract new deposits or retain existing deposits, which could have a material adverse effect on our operating results, financial condition and prospects. Operational Risks 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, global trade tensions could intensify and negatively impact our customers. The U.S. government has introduced significant changes in trade policies, including the imposition of a 10% baseline "reciprocal" tariffs on most imports and nations (including Chile) and higher country-specific tariffs for certain nations with which it has significant trade imbalances. Additionally, the U.S. has threatened to impose higher sanctions on certain nations in certain circumstances. This has led to certain U.S. trading partners announcing reciprocal tariffs (and other actions) in response, leading to increased protectionism and trade tensions across the world, as well as to a depreciation of the U.S. dollar. The continuation, pause or escalation of tariffs and other trade restrictions, the continued depreciation of the U.S. dollar and other non-trade-related actions or policies of the U.S. government, could further impact international trade relations, investment flows and supply chains significantly, resulting in continued market volatility and a reduction in global growth, intensifying concerns over the global macroeconomic environment, inflation and the potential for a recession. Any of the foregoing could have a material adverse effect on our business, results of operations, financial condition and prospects. 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. 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. A slowdown of economic activity, higher unemployment or a market downturn could result in significantly lower fee income. Regulatory changes that modify the fees we may charge could also adversely affect our fee and commission income. In April 2023, the Committee for the Setting of Interchange Fee Caps (an ad hoc, autonomous and technical committee) established new interchange fee caps for credit and debit 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% 9 Table of contents 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 evaluation 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 estimated at Ch$22 billion in the twelve month period starting from when the change is implemented. 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. In addition, the Chilean Congress is currently analyzing an initiative to reduce or limit prepayment fees payable by our customers. As of the date of this Annual Report, the Bank does not yet have an estimate of the potential impact of such initiatives. 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 8—Financial Assets at Amortized Cost” and “Note 6—Financial Assets At Fair Value Through Other Comprehensive Income” in our Audited Consolidated Financial Statements for a description and presentation of our loan portfolio as well as “Item 5. Operating and Financial Review and Prospects—C. Selected Statistical Information—Loan Portfolio.” Retail customers represent 76.3% of the value of the total loan portfolio at amortized cost as of December 31, 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 December 31, 2025, our residential mortgage loan portfolio totaled Ch$17,443,563 million, representing 42.6% of our total loans at amortized cost. See “Note 8—Financial Assets at Amortized Cost” in our Audited 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. Failure to successfully implement and continue to improve our risk management policies, procedures and methods, including our credit risk management systems, could materially and adversely affect us, and we may be exposed to unidentified or unanticipated risks. Risk management is a central part of our activities. We seek to manage and control our risk exposure through forward-looking management model, based on robust governance and advanced risk management tools, supported by a risk culture that permeates the organization. While our management model uses a broad and diversified set of risk monitoring, control and mitigation techniques, such management model may not be fully effective at mitigating our risk exposure in all economic market environments or against all types of risk, including risks that we may fail to identify or anticipate. Some of our tools and metrics for managing risk are based on our use of observed historical market behavior. We apply statistical and other tools to these observations to arrive at quantification of our risk exposures. These tools and metrics may fail to predict future risk exposures. These risk exposures could, for example, arise from factors we did not anticipate or correctly evaluate in our statistical models. This would limit our ability to manage our risks. Our losses thus could be significantly greater than the historical measures indicate. In addition, our statistical models may not take all risks into account or measure emerging risks correctly. 10 Table of contents Our approach to managing risks could prove insufficient, exposing us to material unanticipated losses. We could face adverse consequences as a result of decisions, which may lead to actions by management, based on models that are poorly developed, implemented or used, or as a result of the modelled outcome being misunderstood or the use of such information for purposes for which it was not designed or if the data and inputs of the models were incorrect or insufficient. If existing or potential customers or counterparties believe our risk management is inadequate, they could take their business elsewhere or seek to limit their transactions with us. Any of these factors could have a material adverse effect on our reputation, operating results, financial condition and prospects. As a retail bank, one of the main types of risks inherent in our business is credit risk. For example, an important feature of our credit risk management system is to employ an internal credit rating to assess the particular risk profile of individual customers and SMEs. As this process involves detailed analyses of the customer, taking into account both quantitative and qualitative factors, it is subject to human or information technology systems errors. In exercising their judgment on our customers’ current or future credit risk behavior, our management models may not always be able to assign an accurate credit rating, which may result in a higher exposure to credit risks than indicated by our risk rating system. Some of the models and other analytical and judgment-based estimations we use in managing risks are subject to review by, and require the approval of, our regulators. If models do not comply with all their expectations, our regulators may require us to make changes to such models, may approve them with additional capital requirements or we may be precluded from using them. Any of these possible situations could limit our ability to expand our businesses or have a material impact on our financial results. Failure to effectively implement, consistently monitor or continuously improve our credit risk management system may result in an increase in the level of non-performing loans and a higher risk exposure for us, which could have a material adverse effect on us. In addition, failure to successfully execute any of our decisions and actions affecting or changing our practices, operations, priorities, strategies, policies, procedures, or frameworks, could have a material adverse effect on us. The effectiveness of our credit risk management is affected by the quality and scope of information available in Chile. In assessing customers’ creditworthiness, we rely largely on the credit information available from our own internal databases, the FMC, the Directorio de Información Comercial (Dicom), a Chilean nationwide credit bureau, and other sources. In June 2024, the Chilean Congress passed a law creating a public consolidated debt registry (the “Redec,” pursuant to its Spanish acronym), which will be administered by the FMC and which begun operating in November 2025. The law establishing the Redec requires that entities that were not previously required to report outstanding loans to individuals to report such loans to the FMC, including entities such as servicers of endorsable mortgage loans, family allowance compensation funds, credit card issuers, securitization companies, credit advisory entities regulated by the Chilean Fintec Law, and any other entity supervised by the FMC, as determined by the FMC through a General Regulation. Individuals are explicitly recognized as the owners of their data in Redec and are guaranteed the right to access, update, rectify, and request the cancellation or deletion of their personal data, subject to applicable legal and regulatory limitations. Severe penalties have also been defined for negligent or malicious access or use of information in the Redec. Reporting entities must implement an information system compatible the Redec, which will entail higher costs for entities such as the Bank. Due to limitations in the availability of information and the developing information infrastructure in Chile, our assessment of credit risk associated with a particular customer may not be based on complete, accurate or reliable information. In addition, although we have been improving our credit scoring systems to better assess borrowers’ credit risk profiles, we cannot assure you that our credit scoring systems will collect complete or accurate information reflecting the actual behavior of customers or that their credit risk can be assessed correctly. Without complete, accurate and reliable information, we will have to rely on other publicly available resources and our internal resources, which may not be effective. As a result, our ability to effectively manage our credit risk and subsequently our loan loss allowances may be materially adversely affected. We rely on models for many of our decisions. Their inaccurate or incorrect use could have a material adverse effect on us. We use models for admission (scoring and rating), and behavioral credit processes, for the definition of credit limits, for the calculation of capital, provisions, market and structural risk, operational, compliance and liquidity risk. A model is a system, approach or quantitative method that applies statistical, economic, financial or mathematical theories, techniques or 11 Table of contents hypotheses to transform input data into quantitative estimates and forecasts. It involves simplified representations of real-world relationships between characteristics, values and observed assumptions that allows us to focus on specific aspects. Model risk is the negative consequence of decisions based on inaccurate, improper or incorrect use of models. Sources of model risk include (i) incorrect or incomplete data in the model itself or the modelling method used in systems; and (ii) incorrect use or implementation of the model. Model risk can cause financial loss, erroneous commercial and strategic decision-making or damage to our transactions any of which could have a material adverse effect on our operating results, financial condition and prospects. In addition, our regulatory models and the underlying methodologies are subject to scrutiny from our regulators and supervisory bodies, who could identify potential weaknesses or deficiencies that may result in enforcement actions, including sanctions, fines and/or the imposition of stricter capital requirements, as well as mandates and recommendations with respect to the methodologies underlying our models, which could also lead us to more onerous or inefficient capital consumption. Unprecedented movement in economic and market drivers related to external events requires monitoring and adjusting of financial models (including credit loss models, capital models, traded risk models and models used in the asset/liability management process) to comply with the guidance and recommendations of standard setters, regulators and supervisors, particularly for credit loss and provision models. It also results in the use of mitigants for model limitations, such as adjustments to model outputs to reflect consideration of management judgment. The performance and usage of models was and may continue to be impacted by the consequences of external events. In addition, data obtained during these external events may not be representative and may distort the calibration of the models in the future, which could have a material adverse effect on us. In addition, the fair value of our financial assets, determined using financial valuation models, may be inaccurate or subject to change and, as a consequence, we may have to register impairments or write-downs that could have a material adverse effect on our operating results, financial condition and prospects. See more information in “—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.” 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. If short-term rates continue to fall in 2026, which could increase prepayment risk of our loan book could increase, which would also require us 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 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 this change or any future regulatory changes related to prepayment fees will not have a material impact on our business. If we are unable to manage the growth of our operations or to integrate successfully our inorganic growth, this could have an adverse impact on our profitability. We allocate management and planning resources to develop strategic plans, priorities, policies and targets, including for organic growth, and to identify potential acquisitions, divestitures and areas for restructuring our businesses. The execution of these initiatives is subject not only to external factors but also to our own decisions, including those that alter or redefine our business practices, operational frameworks, strategic objectives, corporate priorities, internal policies, and procedural guidelines. We cannot provide assurance that we will, in all cases, be able to deliver our strategic plans, priorities, policies and targets. Furthermore, in order to grow and remain competitive, we will need to adapt to changes to meet the demands and expectations of regulators, our clients, shareholders and other stakeholders, including in relation to matters of public policy, regardless of whether there is a legal requirement to do so. We cannot guarantee that we will be able to implement changes to any of our strategic plans, priorities, policies and targets, in a timely and appropriate manner, or that we will be able to 12 Table of contents accurately predict trends, initiatives and business practices of financial institutions. It is also possible that regulators, our clients, shareholders and other stakeholders might not be satisfied or even disagree with our strategic plans, priorities, policies and targets, or the speed of their adoption, implementation, evolution and consequences. From time to time, we evaluate acquisition and partnership opportunities that we believe offer additional value to our shareholders and are consistent with our business strategy. However, we may not be able to identify suitable acquisition or partnership candidates, and our ability to benefit from any such acquisitions and partnerships will depend in part on our successful integration of those businesses. Any such integration entails significant risks such as unforeseen difficulties in integrating operations and systems, unexpected liabilities or contingencies relating to the acquired businesses, including legal claims and delivery and execution risks. We can give no assurances that our expectations with regards to integration and synergies will materialize. In addition, any acquisition or venture could result in inconsistencies in standards, controls, procedures and policies. Moreover, the success of any acquisition or venture will, at least in part, be subject to a number of political, economic and other factors that are beyond our control. Any of these factors, individually or collectively, could have a material adverse effect on us. The challenges that may arise from our decisions include: •managing efficiently the operations and employees of expanding businesses; •maintaining or growing our existing customer base; •assessing the value, strengths and weaknesses of investment or acquisition candidates, including local regulation that can reduce or eliminate expected synergies; •financing strategic investments or acquisitions; •aligning our current information technology systems adequately with those of an enlarged group; •applying our risk management policy effectively to an enlarged group; •managing growing number of entities without over-committing management or losing key personnel •meeting the expectations of regulators and our clients, shareholders and other stakeholders with respect to matters of public policy; and •meeting the expectations of regulators and our clients, shareholders and other stakeholders. Any failure to manage growth effectively, an inability to successfully adapt to changing conditions or to execute successfully any of our strategic actions, or any changes in our business practices, operational framework, strategic objectives, corporate priorities, internal policies and procedural guidelines could have a material adverse effect on our operating results, financial condition and prospects. Any failure to improve or upgrade our information technology infrastructure and information management systems and networks in an effective, timely and cost-effective manner, including in response emerging technologies and to new or modified privacy, data protection and cybersecurity laws, rules and regulations could have a material adverse effect on us. Our ability to remain competitive depends in part on our ability to improve or upgrade our information technology in an effective, timely and cost-effective manner. We must continually make significant investments in and improvements to our information technology infrastructure and information management systems and networks in order to meet the needs of our customers and to comply with evolving regulatory requirements, and operational and resilience expectations. While we expect to continue investing, there is no assurance we will achieve or sustain the level of capital expenditures necessary to support the continuous improvement and upgrading of our information technology infrastructure and information management systems and networks. There is also no assurance that our investment strategy will be successful. To the extent we are dependent on any particular technology or technological solution, we may face adverse consequences if such technology or technological solution becomes non-compliant with existing industry standards or applicable laws, rules or regulations, fails to meet or exceed the capabilities of our competitors’ equivalent technologies or technological solutions, becomes increasingly expensive to service, retain and update, becomes subject to third-party claims of intellectual property infringement, misappropriation or other violation, has security vulnerabilities or malfunctions or functions in a way we did not anticipate or are unable to rectify. Additionally, new technologies and technological solutions, such as AI, distributed ledger technology (DLT) and quantum computing, are continually being released. As such, it is difficult to predict the 13 Table of contents problems we may encounter in improving our technologies’ functionality. There is no assurance that we will be able to successfully adopt new technology as critical systems and applications become obsolete and better ones become available. Large scale programs to modernize technology, data and reporting — including compliance with evolving prudential reporting frameworks — are complex and time-consuming (often requiring many years to execute). Delays in execution, data-quality issues, or control weaknesses may lead to supervisory actions, fines, remediation costs or constraints on strategic initiatives. DLT, including blockchain and related infrastructures, is increasingly being explored and adopted across financial markets and payment systems. While these technologies may offer greater efficiency, transparency and traceability, they also introduce specific technological and operational risks and challenges that may affect the integrity and resilience of financial systems. DLT relies on cryptographic consensus mechanisms, distributed governance and, in some cases, open-source protocols, all of which may be vulnerable to design flaws, governance disputes and security vulnerabilities. Limitations in scalability, latency and interoperability across networks may also hinder performance and reliability. Moreover, divergent regulatory approaches across jurisdictions and potential fragmentation of market infrastructures and compliance tools could amplify operational and compliance risks. A growing reliance on DLT-based platforms could disrupt traditional payment, custody and settlement processes, creating dependencies on new technological frameworks and third-party providers. Financial institutions that fail to adapt to such developments may face increased competitive and operational risks. As legacy systems migrate toward hybrid or fully distributed environments, we may encounter transitional, technological and integration challenges affecting system resilience, data integrity and cybersecurity. These factors, individually or in combination, could adversely affect our ability to deliver critical services without disruption, to comply with evolving regulatory and supervisory expectations, and to maintain secure and continuous operations. Any failure to effectively improve or upgrade our information technology infrastructure and information management systems and networks, or to timely adapt to emerging technologies, evolving cybersecurity threats or changing regulatory standards, could have a material adverse effect on us. Any failure or disruption of our operational processes or systems, or any cyberattack, data breach, data loss or other security incident affecting our systems or those of our third-party vendors could adversely affect our business, financial condition or reputation, and could result in significant legal or regulatory exposure. Like other financial institutions, in conducting our banking operations, we receive, manage, hold, transmit and otherwise process certain proprietary, confidential, sensitive and personal data including personal data of customers and employees, as well as a large number of assets. Accordingly, our business relies on our ability to process a large number of transactions efficiently and accurately, and on our ability to rely on our digital technologies, computer and email services, software and networks, as well as on the secure storage, transmission, and other processing of proprietary confidential, sensitive and personal data and other information using our computer systems and networks or those of our third-party vendors, including cloud-based platforms and software-as-a-service (SaaS) solutions. Our operations must also comply with complex and evolving laws and regulations in the countries in which we operate. The proper and secure functioning of our financial controls, accounting and other data collection and processing systems is critical to our business and to our ability to compete effectively. Cyberattacks, data breaches, data losses and other security incidents, including fraudulent withdrawal of money, can result from, among other things, inadequate personnel, inadequate or failed internal control processes and systems, or external events or actors that interrupt normal business operations and may include disruptions, failures, service outages, unauthorized access or misuse, software bugs, server malfunctions, software and hardware failure, defective software or hardware updates, malware and ransomware, social engineering and phishing attacks, denial-of-service attacks, misconduct, fraud, and other events that could have a serious impact on us. We also face the risk that the design of our or our third-party vendors’ cybersecurity controls and procedures prove to be inadequate or are circumvented such that our data or client records are incomplete, not recoverable or not securely stored. Moreover, it is not always possible to deter or prevent employee errors or misconduct, and the precautions we take to detect and prevent this activity may not always be effective. Any material disruption or slowdown of our systems could cause information, including data related to customer requests, to be lost or to be delivered to our clients with delays or errors, which could reduce demand for our services and products, produce customer claims and materially and adversely affect us. We prioritize early identification, monitoring and mitigation of risks (including those resulting from our interactions with third parties) in our goal to provide a resilient and secure operational environment. In this regard, although (i) we have policies, procedures and controls in place designed to safeguard proprietary, confidential, sensitive and personal data, (ii) 14 Table of contents we take protective technical measures and monitor and develop our systems and networks to protect our technology infrastructure, data and information from misappropriation or corruption, and (iii) we work with our clients, vendors, service providers, counterparties and other third parties to develop secure data and information processing, collection, authentication, management, usage, storage and transmission capabilities and to ensure the eventual destruction of proprietary, confidential, sensitive and personal data, we, our third-party vendors or other third parties with which we do business have been and may continue to be subject to cyberattacks, data breaches, data losses and other security incidents. For example, on May 14, 2024, Grupo Santander announced that it had learned of unauthorized access to a Santander database hosted by an external provider, which included certain customer and employee information pertaining to Chile, among other countries. Numerous measures were immediately implemented to manage the incident, such as blocking access to the database, reinforcing fraud prevention, taking preventive actions to avoid the recurrence of a similar incident and maintaining direct contact with regulatory bodies. The implementation of our cybersecurity policies, procedures, controls and technical measures is designed to reduce the risk of such cyberattacks, data breaches, data losses and other security incidents but does not guarantee full protection or a risk-free environment. This is especially applicable in the current global environment, with the wars in Ukraine and the Middle East resulting in an increased risk of cyberattacks, data breaches, data losses and other security incidents and other disruptions in response to, or retaliation for, the sanctions and costs imposed on Russia and certain other countries directly or indirectly involved in the wars. Additionally, the shift to remote work policies for a significant portion of our workforce, as they access our secure systems and networks remotely, and our customers’ increased reliance on digital banking products and other digital services, including mobile payment products, has also increased the risk of cyberattacks, data breaches, data losses and other security incidents. While we generally perform cybersecurity due diligence on our key vendors, because we do not control our vendors and our ability to monitor their cybersecurity is limited, we cannot ensure the cybersecurity measures they take will be sufficient to protect any information we share with them. Due to applicable laws and regulations or contractual obligations, we may be held responsible for cyberattacks, data breaches, data losses and other security incidents attributed to our vendors as they relate to the information we share with them. In addition, we may also be impacted by cyberattacks against national critical infrastructures of Chile, such as telecommunications networks. Our information technology systems are dependent on such critical infrastructure and any cyberattack against such critical infrastructure could negatively affect our ability to service our customers. As we do not operate such critical infrastructure, we have limited ability to protect our information technology systems from the adverse effects of a cyberattack. For further information, see “Item 11. Quantitative and Qualitative Disclosures about Market Risk—2. Non-financial risks—Cyber-security and data security plans.” We have seen in recent years the information technology systems and networks of companies and organizations being increasingly targeted, and the techniques used to obtain unauthorized, improper or illegal access to such information technology systems and networks have become increasingly complex and sophisticated, including through the use of AI. Furthermore, such techniques change frequently and are often not recognized or detected until after they have been launched and can originate from a wide variety of sources, including organized crime, hackers, activists, terrorists, nation-states, nation state-supported actors and others, any of which may see their effectiveness enhanced by the use of AI. As attempted attacks continue to evolve in scope and sophistication, we may incur significant costs in order to modify, adapt or enhance our protective measures against such attacks, or to investigate or remediate any vulnerability or resulting breach, or in communicating cyberattacks, data breaches, data losses or other security incidents to our customers, affected individuals or regulators, as applicable. If we cannot maintain effective and secure proprietary, confidential, sensitive and personal data, or if we or our third-party vendors fall victim to successful cyberattacks, penetrations, compromises, breaches or circumventions of our information technology systems or networks or experience other data breaches, data losses or other security incidents in the future, we may incur substantial costs and suffer other negative consequences, such as disruption to our operations, misappropriation of proprietary, confidential, sensitive or personal data, remediation costs (including liabilities for stolen assets or information, repairs of system damage, among others), increased cybersecurity protection costs, lost revenues arising from the unauthorized use of proprietary, confidential, sensitive or personal data or the failure to retain or attract our customers following an operational or security incident, litigation and legal risks (including claims from customers, employees or other third parties, regulatory action, reporting obligations, investigation, fines and penalties), increased insurance premiums, reputational damage affecting our customers’ and the investors’ confidence, as well as damages to our competitiveness, stock price and long-term shareholder value. In addition, our remediation efforts may not be successful, and we may not have adequate insurance to cover these losses. While we maintain insurance coverage, we cannot assure 15 Table of contents you that such coverage will be adequate or otherwise protect us from liabilities or damages with respect to claims alleging compromises of proprietary, confidential, sensitive or personal data or otherwise relating to privacy, data protection and cybersecurity matters. In addition, we cannot be sure that our existing insurance coverage will continue to be available on acceptable terms or at all, or that our insurers will not deny coverage to any future claim. Moreover, even when a failure of or interruption in our or our third-party vendors’ systems or facilities is resolved in a timely manner or an attempted cyberattack, data breach, data loss or other security incident is successfully avoided or thwarted, substantial resources and management attention are expended in doing so, and to successfully avoid or resolve any such incidents, we may be required to take actions that could adversely affect customer satisfaction or retention, as well as harm our reputation. Any of the cyberattacks, data breaches, data losses and other security incidents described above could have a material adverse effect on our business, financial condition and results of operations. Users and credit card issuers such as us also have obligations when a client’s cards and/or online payment or transfer user information are lost, stolen or fraudulently used (including through hacking and cloning). Cardholders are obligated to notify the bank through an easily accessible channel when their cards have been lost, stolen, or fraudulently used. For those transactions realized prior to the notice of loss or theft of a credit card, the cardholder must also notify the issuer of all of the unauthorized transactions in the same notice or up to five business days following the original notification. In cases of fraud, the user will not be responsible for the transactions that they did not authorize, and which were made prior to the fraud notification within the 30 calendar days following the issuance of said notice. In these cases, issuers are responsible for assuming these costs or must demonstrate that the transaction was in fact authorized by the owner or user of the credit card. The law also considers increasing fines and jail time for those committing theft or fraud with credit cards, which must be legally pursued by the card issuer. In light of these developments, we are trying to limit the exposure of our clients to credit card fraud through education, insurance coverage, marketing campaigns, daily transfer amount limits, chip technology, improved ATM software, and other technological improvements, but we cannot assure that this law will not increase the financial costs related to cybercrime and credit card fraud. We utilize artificial intelligence, which could expose us to liability or adversely affect our business. We utilize, and continue to explore additional uses of AI in connection with our business, products and services, including AI designed to enhance transaction monitoring and sanctions screening, improve customer experience and reduce operational risk. However, there are significant risks involved in utilizing AI and no assurance can be provided that our use will enhance our products or services or produce the intended results. For example, AI models may be flawed, trained on insufficient or poor-quality data, reflect unwanted forms of bias or contain other errors or inadequacies, any of which may not be easily detectable. AI solutions (including those supplied by third parties) may produce false, inaccurate, misleading, biased or otherwise deficient inferences or outputs, rely on data, technology or intellectual property to which we or any of our contractors, vendors or service providers lack rights, or be subject to new documentation, transparency, governance and validation expectations. Strengthening controls to address these risks—such as human oversight, testing and independent model validation—may increase costs and affect time-to-market, and any errors or inadequacies in AI systems used for control functions (such as transaction monitoring or sanctions screening) could lead to operational disruptions, compliance failures, regulatory scrutiny, reputational harm, fines or penalties. AI may subject us to new or heightened legal, regulatory, ethical, operational, reputational or other challenges; AI may involve inappropriate or controversial data practices by developers and end-users, or other factors adversely affecting public opinion of AI, any of which could impair the acceptance of AI solutions, including those incorporated into our products and services. We also depend on third-party models, datasets and infrastructure; outages, changes in functionality or terms, or concentration in a limited number of providers could disrupt our operations or increase costs. If the AI solutions that we create or use are deficient, inaccurate or controversial, we could incur operational inefficiencies, competitive harm, legal liability, brand or reputational harm, or other adverse impacts on our business and financial results. There can be no assurance that our use of AI will be successful in reducing our operational risk or increasing our operational efficiencies or otherwise result in our intended outcomes. Additionally, the use of AI solutions by companies has resulted in and may continue to result in, cyberattacks, data breaches, data losses and other security incidents that implicate the proprietary, confidential, sensitive and personal data of AI users. For example, if any of our employees, contractors, vendors, service providers or other third parties with which we 16 Table of contents do business use any third-party AI-powered solutions in connection with our business, it may lead to the inadvertent disclosure or incorporation of our proprietary, confidential, sensitive or personal data into third-party systems or publicly available or third-party training sets (including so-called 'data leakage') which may impact our ability to realize the benefit of our intellectual property or proprietary, confidential, sensitive or personal data, harming our competitive position and business. If we do not have sufficient rights to use the data or other material or content on which our AI solutions or other AI tools we use rely, we also may incur liability through the violation of applicable laws and regulations, third-party intellectual property, privacy or other rights, or contracts to which we are a party (including third-party claims of intellectual property infringement, misappropriation or other violation or other misuse of data, content or technology, regulatory enforcement actions and contractual remedies). Further, the use of AI solutions within products or services that we use or that are used by our contractors, vendors, service providers or other third parties with which we do business may pose similar risks, and we have limited ability to control the manner in which third-party products are developed or maintained or the manner in which third-party services are provided. We rely on third parties and affiliates for important products and services. Third party vendors and certain affiliated companies provide key components of our business infrastructure such as loan and deposit servicing systems, back office and business process support, information technology production and support, Internet connections and network access including cloud-based services and software-as-a-service (SaaS) solutions, as well as those of our service providers. Relying on these third parties and affiliated companies can be a source of operational and regulatory risk to us, including with respect to security breaches, service outages and other disruptions or failures affecting such parties. We are also subject to risk with respect to security breaches, service outages and other disruptions or failures affecting the vendors and other parties that interact with these service providers. As our interconnectivity with these third parties and affiliated companies increases, we increasingly face the risk of operational failure with respect to their systems. We may be required to take steps to protect the integrity of our operational systems, thereby increasing our operational costs and potentially decreasing customer satisfaction. In addition, any problems caused by these third parties or affiliated companies, including as a result of them not providing us their services for any reason, or performing their services poorly, could adversely affect our ability to deliver products and services to customers and otherwise conduct our business, which could lead to reputational damage and regulatory investigations and intervention. Replacing these third-party vendors could also entail significant delays and expense. Further, the operational and regulatory risk we face as a result of these arrangements may be increased to the extent that we restructure such arrangements. Any restructuring could involve significant expense to us and entail significant delivery and execution risks, which could have a material adverse effect on our business, operations and financial condition. Damage to our reputation could cause harm to our business prospects. Maintaining a robust risk management framework based on sound ethical principles and corporate values is critical to protect our reputation and our brand, attract and retain customers, investors and employees and conduct business transactions with counterparties. Damage to our reputation could materially and adversely affect how we are perceived by current and potential clients, investors, vendors, partners, regulators and other third parties, which in turn could have a material adverse effect on our operating results, financial condition, and prospects as well as damage our customers’ and investors’ confidence and the market price of our securities. Harm to our reputation could arise from numerous sources, including, among others, employee misconduct (such as fraud or unethical behavior), litigation or regulatory enforcement, failure to deliver minimum standards of service and quality, negative perceptions regarding our ability to maintain the security of our technology systems and protect customer data (including as a result of a cyberattack, data breach, data loss or other security incident), dealing with sectors that are not well perceived by the public (such as weapons industries or embargoed countries), dealing with customers in sanctions lists, rating downgrades, significant variations in our share price over time, compliance failures, unethical behavior, actual or alleged improper conduct in areas such as lending, sales, marketing, corporate governance or culture, and the activities of customers and counterparties, including activities that negatively affect the environment. Our reputation could also suffer if we are the subject of negative coverage in the media, whether it has merit or not. Actions by the financial services industry generally or by certain members of, or individuals in, the industry can also affect our reputation. For example, the role played by financial services firms in the financial crisis and the resulting shift toward increasing regulatory supervision and enforcement have led to a decline in public perception of us and others in the financial services industry to decline. 17 Table of contents Additionally, we could suffer significant reputational harm from negative perceptions regarding our approach to environmental, social and corporate governance policies. There has been increased focus by customers, shareholders, investor advocacy groups, employees, regulators and other stakeholders on these topics, and our policies, practices and disclosures in these areas could come under scrutiny. Governments may implement new or additional regulations and standards, or investors, customers and other stakeholders may impose new expectations or focus investments in ways that cause significant shifts in disclosure, consumption and behaviors that may have negative impacts on our business. If regulators or stakeholders consider our efforts ineffective, inadequate or unsatisfactory, whether real or perceived, it could harm our reputation, business and prospects and we could be subject to enforcement or other supervisory actions. We could also suffer significant reputational harm if we fail to identify and manage potential conflicts of interest properly. The failure, or perceived failure, to adequately address conflicts of interest could affect the willingness of clients to deal with us or could result in litigation or enforcement actions against us which could have an adverse effect on our operating results, financial condition and prospects. We may be the subject of misinformation and misrepresentations deliberately propagated to harm our reputation or for other deceitful purposes, including by short sellers seeking to profit by spreading false or misleading information about us. There can be no assurance that we will effectively neutralize and contain any false information that may be propagated regarding the business, which could have an adverse effect on our operating results, financial condition and prospects. Financial Risks 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 and other 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 internal methodologies dependent 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 2025, Moody’s maintained its A2 credit rating and S&P maintained its A rating for the Republic of Chile. 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. Downgrades in our debt credit ratings have in the past, and would likely in the future, 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 on 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 our ratings will be linked, to a large extent, to the impact of the general global macroeconomic outlook 18 Table of contents (including as a result of the continuance or escalation of the war in Ukraine and the uncertainties following the ceasefire agreement in the Middle East, the local macroeconomic outlook, the evolution of Chile’s political environment, especially in relation to potential projects to amend Chile’s constitution, the Chilean government’s fiscal policy and the outlook of our asset quality, profitability and capital. Failure to maintain favorable ratings and outlooks could increase our cost of funding and adversely affect interest margins, which could have a material adverse effect on us. 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 hold significant exposures to securities, loans and other investments recorded at fair value which exposes us to potential negative fair value adjustments. Asset valuations in future periods, reflecting then-prevailing market conditions, may result in negative changes in the fair values of our financial assets and these may also translate into increased impairments including as a result of more stringent regulatory or reputational requirements. In addition, the value ultimately realized by us on disposal may be lower than the current fair value. Any of these factors could require us to record negative fair value adjustments, which may have a material adverse effect on our operating results, financial condition or prospects. As of December 31, 2025, the value of our debt instruments at fair value through other comprehensive income includes an unrealized net loss of Ch$77,905 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, judgments and estimates in order to establish fair value. Reliable assumptions are difficult to make and are inherently uncertain while valuation models are inherently complex and imperfect predictors of actual results. Any consequential impairments or write-downs could have a material adverse effect on our operating results, financial condition and prospects. The value of the collateral securing our loans may decline and 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 war in Ukraine and the uncertainties following the ceasefire agreement in 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. We may also lack sufficiently recent information on collateral values, which may result in an inaccurate assessment for impairment losses of our loans secured by such collateral. If any of the above were to occur, we may need to make additional provisions to cover actual impairment losses, which could materially and adversely affect our results of operations and financial condition. Technological changes in the auto industry, accelerated by environmental regulations, could affect our auto consumer business in Chile, particularly residual values of leased vehicles. This transformation could impact our auto finance business as a result of (i) the 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) increased market concentration in certain manufacturers, distributors and other agents; and (iv) the expansion of online sales channels. In addition, the auto industry could face supply chain disruption and shortages of batteries, semi-conductors and other components linked to geopolitical tensions, conflicts and macroeconomic uncertainty, affecting guarantees, residual used car value and loan delinquencies. Although we monitor the auto portfolios and dealers and we have launched specific action plans to address particular issues, these structural changes and disruptions could have a material adverse effect on our operating results, financial condition and prospects. 19 Table of contents As of December 31, 2025, 69.0% of our loans and advances to customers at amortized cost are collateralized, which includes 8.8% of our consumer loans, 98.4% of our mortgage loans and 58.6% 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 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, supply chain issues, labor shortages and increases in commodity prices (including as a result of increased tariffs or the continuance or escalation of the war in Ukraine and the uncertainties following the ceasefire agreement in 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 December 31, 2025, our non-performing loans were Ch$1,332,660 million, and the ratio of our non-performing loans to total loans at amortized cost was 3.26% compared to 3.17% as of December 31, 2024. The increase in this ratio was mainly due to increased risk in consumer and residential mortgage loans offset by a decline in the non-performing commercial loan ratio, which 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. In consumer and mortgage loans, the increase in credit risk is mainly due to the persistently high level of unemployment in the economy. As of December 31, 2025, our allowance for expected credit losses for loans classified as financial assets at amortized costs was Ch$1,222,458 million, and the ratio of these allowances for expected loan losses to total loans at amortized cost was 2.99%. For additional information on our asset quality, see “Item 5. Operating and Financial Review and Prospects—C. 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. Our financial results are constantly exposed to market risk. We are subject to fluctuations in interest rates and other market variables, which may materially and adversely affect us and our profitability. Our financial results are constantly exposed to market risk. Economic activities exposed to market risk include (i) transactions where risk is assumed as a consequence of potential changes in interest rates, inflation rates, exchange rates, stock prices, credit spreads, commodity prices, volatility and other market factors; (ii) the liquidity risk from our products and markets; and (iii) balance sheet-related liquidity risk. Interest rate risk arises from movements in interest rates that reduce the value of a financial instrument, a portfolio or the Bank. It can affect loans, deposits, debt securities, most assets and liabilities held for trading, and derivatives. Interest rates are sensitive to many factors beyond our control, including monetary policies, regulatory actions affecting the financial sector and domestic and international economic and political conditions. Variations in interest rates could affect the interest earned on our assets and the interest paid on our borrowings, thereby affecting our interest income / (charges), which constitutes the majority of our revenue, and could reduce our growth rate or result in losses. In addition, 20 Table of contents costs we incur as we implement strategies to reduce interest rate exposure could increase in the future, which could in turn affect our results. A low-interest rate environment, such as that experienced in Chile in 2020 and 2021, could result in rates on our interest earning assets being priced at continuously lower rates but as interest bearing time deposits in Chile are not allowed to offer rates below zero, this limits our ability to reduce time deposit rates, thereby, potentially negatively impacting our margins and our results of operations. Throughout 2022 and 2023, central banks globally, including the Central Bank of Chile, considerably increased interest rates to contain inflation. From 2023 onwards, inflation gradually converged towards central bank's objectives, enabling interest rate cuts in the second half of 2024 and throughout 2025. Increases in interest rates may reduce the volume of loans we originate. Sustained high interest rates have historically discouraged customers from borrowing and have resulted in increased in delinquencies in outstanding loans and deterioration in the quality of assets. Increases in interest rates may reduce the value of our financial assets and may reduce gains or require us to record losses on sales of our loans or securities. Additionally, a flattening or inversion of the yield curve, combined with persistent inflationary pressures, could adversely affect our business and results of operations. High levels of inflation in Chile could adversely affect the Chilean economy and our business, financial condition and results of operations (“—Inflation, government efforts to control inflation, and changes in interest rates may hinder the growth of the Chilean economy and could have an adverse effect on us.”). Any change in the methodology of how the CPI index or the UF are calculated could also adversely affect our business, financial condition and results of operations. Extended periods of deflation could also have an adverse effect on our business, financial condition and results of operations. The UF is revalued in monthly cycles. On each day in the period beginning on the tenth day of any given 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. For more information regarding the UF, see “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Impact of Inflation.” Although we benefit from inflation in Chile 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 no corresponding features in deposits, or other funding sources that would increase the size of 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, including from extended periods of inflation that adversely affect economic growth or periods of deflation. “See Item 11. Quantitative and Qualitative Disclosure About Market Risks—Market Risk: Quantitative Disclosure—Impact of Inflation.” We are also exposed to foreign exchange rate risk as a result of mismatches between assets and liabilities denominated in different currencies. Fluctuations in the exchange rate between currencies may negatively affect our earnings and value of our assets and securities. Therefore, while the Bank seeks to avoid significant mismatches between assets and liabilities due to foreign currency exposure, from time to time, we may have mismatches. The Chilean peso has been subject to large devaluations and appreciations in the past and could be subject to significant fluctuations in the future. Our results of operations may be affected by fluctuations in the exchange rates between the peso and the dollar despite our policy and Chilean regulations relating to the general avoidance of material exchange rate exposure. In order to avoid material exchange rate exposure, we enter into forward exchange transactions. We may decide to change our policy regarding exchange rate exposure. Regulations that limit such exposures may also be amended or eliminated. Greater exchange rate risk will increase our exposure to the devaluation of the peso, and any such devaluation may impair our capacity to service foreign currency obligations and may, therefore, materially and adversely affect our financial condition and results of operations. Notwithstanding the existence of general policies and regulations that limit material exchange rate exposures, the economic policies of the Chilean government, new foreign currency regulations by the Central Bank and any future fluctuations of the peso against the dollar could affect our financial condition and results of operations. “See Item 11. Quantitative and Qualitative Disclosure About Market Risks—Market Risk: Quantitative Disclosure—Foreign exchange fluctuations.” Global events (such as the continuance or escalation of the war in Ukraine and the uncertainties following the ceasefire agreement in the Middle East) and the recent imposition and threat of tariffs by the elected U.S. government have caused 21 Table of contents and could continue to cause high market volatility, which could materially and adversely affect us and our trading and banking book. Equity risk is the possibility of loss from open positions in securities if their market price or expected future dividends fall. It affects shares, stock market indices, convertible bonds and derivatives with shares as the underlying asset (put, call, equity swaps, etc.). The performance of financial markets may cause changes in the value of our investment and trading portfolios. Prolonged volatility in global equity and fixed-income markets—driven by geopolitical uncertainty, monetary tightening cycles, and investor risk aversion—has had a significant impact on the financial sector. Continued volatility may affect the value of our investments in equity securities and, depending on their fair value and future recovery expectations, could result in a permanent impairment requiring write-offs against our results. Other market risks include inflation rate risk, credit spread risk, commodity price risk and volatility risk. Additionally, we are also exposed to more complex market risks such as correlation risk, market liquidity risk, prepayment or cancellation risk and subscription risk. In addition, balance sheet liquidity risk (unlike market liquidity risk) is the possibility of loss caused by forced disposal of assets or cash flow imbalance if the bank meets its payment obligations late or at excessive cost. Such situations may cause losses through forced asset sales or margin compression resulting from mismatches between expected inflows and outflows. Market risk affects (i) our interest income / (charges); (ii) the market value of our assets and liabilities, in particular of our securities holdings, loans and deposits and derivatives transactions; and (iii) other areas of our business such as the volume of loans originated or credit spreads. Market risk could also include unforeseen risks arising during periods of market disruption or when market prices do not reflect fundamental values. If any of these risks were to materialize, our operating results or the market value of our assets and liabilities could suffer a material adverse impact. 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. Any deficiencies in these controls or systems could heighten the risks associated with derivative transactions and could have a material adverse effect on us. The use of derivative instruments may also give rise to other risks, including valuation risk, model risk and market liquidity risk, particularly during periods of volatility or market stress. In such circumstances, the fair value of derivative positions may fluctuate significantly, affecting our results and regulatory capital. As of December 31, 2025, the fair value of the trading derivatives in our assets amounted to Ch$10,879,777 million with a notional value of Ch$306,629,511 million. Additionally, as of December 31, 2025, the fair value of trading derivatives in our liabilities totaled Ch$10,587,308 million with a notional value of Ch$288,862,589 million. As of December 31, 2025, the nominal value of the hedging derivatives in our books held within our financial risk management strategy and designed to reduce asymmetries in the accounting treatment of our operations amounted to Ch$27,741,554 million (with market value of Ch$261,192 million in assets and Ch$912,716 million in liabilities). 22 Table of contents 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 major 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 the continuance or escalation of the war in Ukraine and the uncertainties following the ceasefire agreement in 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. Variations in credit spreads are market-driven and may be influenced by perceptions of our creditworthiness and general market conditions.Changes to interest rates and our credit spreads may occur frequently and could be unpredictable and highly volatile. 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 December 31, 2025, 98.5% 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 24.2% and 25.0% of our total liabilities and equity as of December 31, 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 December 31, 2025, the Bank’s top 20 time deposits represented 20.0% of total time deposits, or 4.8% of total liabilities and 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. 23 Table of contents 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. Changes to the pension fund system may affect our liquidity levels and/or funding costs The current pension fund system dates back to the 1980s, when pensions were converted from a state-funded system to a privately-funded system. Before 2025, employees were required by law to set aside 10% of their wages in a private pension fund. The demographics of Chilean society have changed in recent decades, led the government to enact a general reform of the system in January 2025 pursuant to Law No. 15480-13. In addition to the 10% of wages set aside by employees, employers are now required to contribute 7% of their employees’ taxable income. This contribution will be phased in over a period of 9 years, in addition to the existing 1.5% employer contribution to the Disability and Survivors Insurance (“SIS”). This reform brings the total employer contribution to 8.5% of an employee's salary. Between 2020 and 2021, in the context of the COVID-19 pandemic, Chilean Congress enacted several laws which allowed Chileans to withdraw certain pre-established amounts from their pension funds without any penalties, which resulted in approximately U.S.$49 billion of liquidity being withdrawn from pension funds and injected into the Chilean economy. Withdrawals had an immediate impact on local fixed income capital markets and inflation. In 2025, there were no additional pension fund withdrawals approved but no assurances can be made as to whether there will be additional withdrawals in the future or whether the withdrawals will have a material adverse effect on our financial condition, liquidity levels, and our ability to obtain funding from the AFPs. Chilean regulations also impose a series of restrictions on how Chilean pension fund administrators (Administradora de Fondos de Pensión, or “AFPs”) may allocate their assets. In the particular case of financial issuers’ there are three restrictions, each involving different assets and different limits determined by the amount of assets in each fund and the market and book value of the issuer’s equity. Overall, AFPs cannot invest more than 6.5% of the total funds managed in a single Chilean bank issuer. As of September 30, 2025, the most recent date for which information is available, the Chilean pension fund administrators (Administradora de Fondos de Pensión, or “AFPs”) had U.S.$$3.54 billion invested in the Bank via equity, deposits and fixed income securities. According to our estimates, as of September 2025, the AFPs still had the possibility of being able to invest another U.S.$10.9 billion in the Bank via equity, deposits and fixed income. As a result, any changes in the pension system, including any changes in the way the system invests in Chilean assets, could affect our liquidity levels and/or funding costs. If the exposure of any AFP to Santander-Chile exceeds the regulatory limits, if the regulatory limits are reduced or the amount of funds available in the pension funds falls significantly, we would need to seek alternative sources of funding, which could be more expensive and, as a consequence, may have a material adverse effect on our financial condition and results of operations. Legal and Regulatory Risks We are subject to regulatory capital requirements that could limit our operations, and changes to these requirements may further limit and adversely affect our operating results, financial condition and prospects. On October 9, 2020, the FMC published the regulations on regulatory capital to comply with effective net worth rules in accordance with Basel III and the General Banking Law. The new regulation became effective on December 1, 2021 and was gradually implemented to be fully effective by December 1, 2025. For further details of capital requirements, please see “Item 4 Information on the Company—B. Business Overview-Regulation and Supervision—Minimum Capital.” The General Banking Law also incorporates Pillar II capital requirements to ensure adequate risk management,which are currently still being updated and phased-in. This pillar’s objective is to ensure that banks maintain capital levels consistent with their risk profile and business model and encourage the development and use of appropriate processes to monitor and manage their risks. Pillar II also granted regulators the power to impose greater capital requirements because of deficient evaluations of a bank’s internal capital adequacy assessment process (ICAAP), which should consider a bank’s risk profile and a strategy to sustain adequate levels of capital, even under stress scenarios. The FMC, with at least four votes from the Council of the FMC, will have the power to impose additional regulatory capital demands of up to 4% of risk-weighted assets, either Tier I or Tier II, if it determines that the previous capital levels and buffers are not enough for a particular financial institution. On April 11, 2025, the FMC set a 0.25% Pillar II requirement was for the Bank. 50% of this Pilar 2 capital requirement (0.125% of risk weighted assets) was constituted by June 30, 2025 as mandated by the FMC. On January 16, 2026 and following the completion of the FMC's annual supervisory process, the FMC determined that the 0.125% Pilar II requirement for Santander Chile was sufficient. Every year the FMC will perform an annual capital 24 Table of contents adequacy assessments analysis as part of its supervisory process, which could result in a higher Pilar II capital requirement and, therefore, we cannot rule out having to raise additional capital in the future in order to maintain our capital adequacy ratios above the minimum required by the FMC. On December 12, 2023, the FMC published for public comment a proposal to amend the regulations 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 possibility to impose capital requirements for the full amount of the IRRBB, 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 the variation in the economic value of equity (ΔEVE) while adding new thresholds for sensitivity of 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 UF) while differentiating interest rate shocks for short- and long -term risk for inflation linked positions (UF), (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 II Requirement and Pillar II Guidance concepts, and (vii) the establishment of new disclosure requirements for Pillar II 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 Chilean banking industry in the future, including us. Therefore, we cannot guarantee that our profitability will not be impacted by actions we may be required to take in order to fulfill new regulatory capital requirements which may be established by the FMC in the future. We believe our current capital levels are adequate, but we cannot rule out having to raise additional capital in the future in order to maintain our capital adequacy ratios above the minimum required by the FMC. Our ability to raise additional capital may be limited by numerous factors, including: our future financial condition, results of operations and cash flows; any necessary government regulatory approvals; our credit ratings; general market conditions for capital raising activities by commercial banks and other financial institutions; and domestic and international economic, political and other conditions. If we require additional capital in the future, we cannot assure you that we will be able to obtain such capital on favorable terms, in a timely manner or at all. Furthermore, the FMC may increase the minimum capital adequacy requirements applicable to us. Accordingly, although we currently meet the applicable capital adequacy requirements, we may face difficulties in meeting these requirements in the future. If we fail to meet the capital adequacy requirements, we may be required to take corrective actions. These measures could materially and adversely affect our business reputation, financial condition and results of operations. In addition, if we are unable to raise enough capital in a timely manner, the growth of our loan portfolio and other risk-weighted assets may be restricted, and we may face significant challenges in implementing our business strategy. As a result, our prospects, results of operations and financial condition could be materially and adversely affected. For further details of capital requirements, please see “Item 4 Information on the Company—B. Business Overview-Regulation and Supervision—Minimum Capital.” 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 require Chilean banks to maintain liquidity levels that are in line with those established in Basel III. The most important liquidity ratios are: •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. •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 implementation of internationally accepted liquidity ratios might require changes in business practices that affect our profitability. 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 25 Table of contents of December 31, 2025 our LCR and NSFR were 188% and 115%, 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. We are subject to extensive regulation and regulatory and governmental oversight which could adversely affect our business, operations and financial condition. As a financial institution, we are subject to extensive regulation, inspections, examinations, inquiries, audits and other regulatory requirements by Chilean regulatory authorities, which materially affect our businesses. 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. We cannot assure you that we will be able to meet all of the applicable regulatory requirements and guidelines, or that we will not be subject to sanctions, fines, restrictions on our business or other penalties in the future as a result of noncompliance. If sanctions, fines, restrictions on our business, higher capital requirements or other penalties are imposed on us for failure to comply with applicable requirements, guidelines or regulations, our business, financial condition, results of operations and our reputation and ability to engage in business may be materially and adversely affected. 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. In August 2021, Law No. 21,365 was enacted, regulating interchange fees in the credit card payment market in Chile. An autonomous and technical committee was formed to determine the interchange fee limits, conformed by 4 members designated by the Central Bank, the FMC, the National Economic Prosecutor (Fiscalía Nacional Económica) and the Ministry of Finance. Interchange fee limits will be determined every three years. In February 2023, the Committee for the Setting of Interchange Fee Caps proposed new interchange rate caps for credit and debit cards, reducing fees which banks may charge on acquirers. Implementation of the second phase of this change is currently on hold. If resumed, we expect that this reduction will have a significant impact on our revenue from card fees and is estimated to have an negative impact of approximately Ch$22 billion in the twelve month period starting from when the change is implemented. (see “Item 3. Key Information—D. Risk Factors—Risks in Respect of Santander-Chile—We may generate lower revenues from fee and commission-based businesses.”) In addition, on January 28, 2025, the Chilean government submitted a bill aimed at mitigating the impact of high interest rates on mortgage loans by reducing these rates, benefitting buyers by lowering their monthly payments. This bill also proposes the implementation of a state subsidy designed to facilitate home purchases for middle-income families and reactivate the construction and real estate sectors. The benefit consists of a subsidy of up to 60 basis points on the interest rate for mortgage loans and applies to homes valued at no more than UF 4,000 (approximately U.S.$133,000). Additionally, the subsidy is complemented by a state guarantee denominated “Garantías Apoyo a la Vivienda Nueva”, which will be available to individuals or legal entities that meet all the following eligibility criteria: (i) the credit must be for financing new housing, (ii) the property's value must not exceed UF 4,000 and (iii) it must comply with the additional requirements established in the relevant decrees. Furthermore, the fund cannot guarantee more than 60% of the property's value. The goal is to support families who, while not in a vulnerable situation, face difficulties in saving for the down payment required to purchase a home. The bill was approved by the Congress and was finally published as Law No. 21,748 on May 29, 2025. In June 2024, the Chilean Congress passed a law creating a public consolidated debt registry (the “Redec,” pursuant to its Spanish acronym), which will be administered by the FMC and which begun operating in November 2025. (See “Item 3. Key Information—D. Risk Factors—Competitve Risks- The effectiveness of our credit risk management is affected by the quality and scope of information available in Chile). 26 Table of contents In January 2023 the law on Fintech and Open Finance System was published and in July 2024, the FMC published the regulations governing the Open Finance System (or the “SFA” pursuant to its Spanish acronym) under the Fintech Law, which is expected to enter into force in July 2026. (See “Item 3. Key Information—D. Risk Factors—Competitve Risks- The effectiveness of our credit risk management is affected by the quality and scope of information available in Chile). In their supervisory roles, the regulators seek to maintain the safety and soundness of financial institutions with the aim of strengthening the protection of customers and the financial system. The supervisors’ continuing supervision of financial institutions is conducted through a variety of regulatory tools, including the collection of information by way of prudential returns, reports obtained from skilled persons, visits to firms and regular meetings with management to discuss issues such as performance, risk management and strategy. In general, these regulators have a more outcome-focused regulatory approach that involves more proactive enforcement and more punitive penalties for infringement. As a result, we face increased supervisory scrutiny (resulting in increasing internal compliance costs and supervision fees), and in the event of a breach of our regulatory obligations we are likely to face more stringent regulatory fines. Changes in 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. As some of the banking laws and regulations have been recently adopted, the manner in which those laws and related regulations are applied to the operations of financial institutions is continuously evolving. Moreover, to the extent these recently adopted regulations are implemented inconsistently in the various jurisdictions in which we operate, we may face higher compliance costs. No assurance can be given generally that laws or regulations will be adopted, enforced or interpreted in a manner that will not have a material adverse effect on our business and results of operations. Chilean authorities and legislators periodically consider initiatives aimed at strengthening consumer protections, debtor rights, and addressing household over-indebtedness. Legislative proposals currently under discussion in the National Congress include measures intended to facilitate refinancing for highly indebted consumers, regulate aspects of credit card payment practices, impose greater restrictions on certain prepayment charges, enhance disclosure standards, and expand supervisory powers over elements of consumer credit activity. For example, Proposed Bill No. 16.408-05, introduced in 2023 and still under discussion before the Chilean Congress, seeks to reduce and prevent over-indebtedness through refinancing mechanisms, regulation of credit card payment practices, and related consumer protection reforms under Law No. 19.496, as amended. Since 2019, there has been continuous discussion in Congress on proposals to amend laws and regulations regarding consumer credit protections, including provisions relating to prepayment rules, acceleration clauses, and related credit charges. These initiatives remain subject to legislative debate and modification, and their final scope and outcome are uncertain. Any such changes, if enacted, could affect our interest income, fee generation, or credit management practices, which in turn could have a material adverse effect on our operating results, financial condition, and prospects. We are subject to regulation by the FMC and by the Central Bank with regard to certain matters, including reserve requirements, interest rates, foreign exchange mismatches and market risks (see more details on “Item 4. Information on the Company—B. Business Overview—Regulation and Supervision”). Chilean laws, regulations, policies and interpretations of laws relating to the banking sector and financial institutions are continually evolving and changing. Any new reforms could result in increased competition in the industry and thus may have a material adverse effect on our financial condition and results of operations. Pursuant to the General Banking Law, all Chilean banks may, subject to the approval of the FMC, engage in certain businesses other than commercial banking depending on the risk associated with such business and their financial strength. Such additional businesses include securities brokerage, mutual fund management, securitization, insurance brokerage, leasing, factoring, financial advisory, custody and transportation of securities, loan collection and financial services. The General Banking Law also applies to the Chilean banking system a modified version of the capital adequacy guidelines issued by the Basel Committee on Banking Regulation and Supervisory Practices and limits the discretion of the FMC to deny new banking licenses. There can be no assurance that regulators will not in the future impose more restrictive limitations on the activities of banks, including us. Any such change could have a material adverse effect on our financial condition or results of operations. Historically, Chilean banks have not paid interest on amounts deposited in checking accounts. We have begun to pay interest on some checking accounts under certain conditions. If competition or other factors lead us to pay higher interest rates on checking accounts, to relax the conditions under which we pay interest or to increase the number of checking accounts on which we pay interest, any such change could have a material adverse effect on our financial condition or results of operations. 27 Table of contents 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 December 31, 2024 and 2025, the Bank was not required to, and did not constitute, a corresponding technical reserve. We may not be able to detect or prevent money laundering and other financial crime activities fully or on a timely basis, which could expose us to additional liability and could have a material adverse effect on us. We are required to comply with applicable anti-money laundering anti-terrorism (“AML/CFT”), anti-bribery and corruption, sanctions and other laws and regulations (collectively, financial crime compliance (“FCC”) regulations). These laws and regulations require us, among other things, to conduct full customer due diligence (including sanctions and politically exposed person screening), keep our customer, account and transaction information up to date and have implemented FCC policies and procedures detailing what is required from those responsible. We are also required to conduct FCC training for our employees and to report suspicious transactions and activity to appropriate law enforcement following full investigation by our FCC team. Financial crime continues to be the subject of enhanced regulatory scrutiny and supervision by regulators globally. AML/CFT, anti-bribery and corruption and sanctions laws and regulations are increasingly complex and detailed. The Basel Committee has introduced guidelines to strengthen the interaction and cooperation between prudential and AML/CFT supervisors. Compliance with these laws and regulations requires automated systems, sophisticated monitoring and skilled compliance personnel. We maintain updated policies and procedures aimed at detecting and preventing the use of our banking network for money laundering and other financial crime related activities. However, emerging technologies, such as cryptocurrencies and innovative payment methods, could limit our ability to track the movement of funds. Our ability to comply with the legal requirements depends on our ability to improve detection and reporting capabilities and reduce variation in control processes and oversight accountability. These require implementation and embedding within our business effective controls and monitoring, which in turn requires on-going changes to systems and operational activities. Financial crime is continually evolving and is subject to increasingly stringent regulatory oversight and focus. This requires proactive and adaptable responses from us so that we are able to deter threats and criminality effectively. Even known threats can never be fully eliminated, and there will be instances where we may be used by other parties to engage in money laundering and other illegal or improper activities. In addition, we rely heavily on our employees to assist us by spotting such activities and reporting them, and our employees have varying degrees of experience in recognizing criminal tactics and understanding the level of sophistication of criminal organizations. Where we outsource any of our customer due diligence, customer screening or anti financial crime operations, we remain responsible and accountable for full compliance and any breaches. If we are unable to apply the necessary scrutiny and oversight of third parties to whom we outsource certain tasks and processes, there remains a risk of regulatory breach. If we are unable to comply fully with applicable laws, regulations and expectations, our regulators and relevant law enforcement agencies have the ability and authority to impose significant fines and other penalties on us, including requiring a complete review of our business systems, day-to-day supervision by external consultants and ultimately the revocation of our banking license. We have been, and may in the future be, subject to negative coverage in the media about us or our clients, including with respect to alleged conduct such as failure to detect and/or prevent any financial crime activities or comply with FCC regulations. Negative media coverage of this type about us, whether it has merit or not, could materially and adversely affect our reputation and perception among current and potential clients, investors, vendors, partners, regulators and other third parties, which in turn could have a material adverse effect on our operating results, financial condition and prospects as well as damage our customers’ and investors’ confidence and the market price of our securities. 28 Table of contents The reputational damage to our business and global brand could be severe if we were found to have breached AML/CFT, anti-bribery and corruption or sanctions requirements. Our reputation could also suffer if we are unable to protect our customers’ bank products and services from being used by criminals for illegal or improper purposes. In addition, while we review our relevant counterparties’ internal policies and procedures with respect to such matters, we expect our relevant counterparties to maintain and properly apply their own appropriate compliance procedures and internal policies. Such measures, procedures and internal policies may not be completely effective in preventing third parties from using our (and our relevant counterparties’) services as a conduit for illicit purposes (including illegal cash transactions) without our (and our relevant counterparties’) knowledge. If we are associated with, or even accused of being associated with, breaches of AML/CFT, anti-bribery and corruption or sanctions requirements, our reputation could suffer and/or we could become subject to fines, sanctions and/or legal enforcement (including being added to “watch lists” that would prohibit certain parties from engaging in transactions with us), any one of which could have a material adverse effect on our operating results, financial condition and prospects. Any such risks could have a material adverse effect on our operating results, financial condition and prospects. We are exposed to risk of loss from legal and regulatory proceedings. We face risk of loss from legal and regulatory proceedings, including tax proceedings, that could subject us to monetary judgments, regulatory enforcement actions, fines and penalties. The current regulatory and tax enforcement environment in the jurisdictions in which we operate reflects an increased supervisory focus on enforcement. Combined with uncertainty about the evolution of the regulatory regime, this may lead to material operational and compliance costs. We are from time to time subject to regulatory investigations and civil and tax claims, and party to certain legal proceedings incidental to the normal course of our business, including, among others, in connection with conflicts of interest, lending and derivatives activities, relationships with our employees and other commercial, privacy, data protection, cybersecurity, tax or climate related matters. In view of the inherent difficulty of predicting the outcome of legal matters, particularly where the claimants seek very large or indeterminate damages, or where the cases present novel legal theories, involve a large number of parties, are in the early stages of investigation or discovery, or have common elements but require assessment of circumstances on a case-by-case basis, we cannot state with certainty what the eventual outcome of these pending matters will be or what the eventual loss, fines or penalties related to each pending matter may be. The amount of our reserves in respect of these matters, which considers the likelihood of future cash flows associated with each of such claims, is substantially less than the total amount of the claims asserted against us, and, in light of the uncertainties involved in such claims and proceedings, there is no assurance that the ultimate resolution of these matters will not significantly exceed the reserves currently accrued by us. As a result, the outcome of a particular matter may be material to our operating results for a particular period. As of December 31, 2025, we had provisions for legal contingencies of Ch$3,933 million. RISK FACTORS IN RESPECT OF CHILE Political, legal, regulatory and economic uncertainty arising from social unrest and the resulting social reforms, as well as the potential enactment of a new constitution could adversely impact the Bank’s business. During October 2019, growing public concern over perceived social inequality led to a rise in social unrest. The social unrest caused commercial disruptions throughout the country. After three weeks of nationwide protests, the Chilean government announced in November 2019 that it would initiate a process to draft a new Constitution for Chile. When the government announced the process of enacting a new constitution, there was increased volatility in the Chilean stock market and exchange rate fluctuations that resulted in a weakening of the Chilean peso against the U.S. dollar. The share prices of local banks and bond spreads, including those of Santander Chile, suffered significant deterioration in the market. After a prolonged process, two plebiscites to approve two proposed draft of the constitution were rejected. As a result, the constitution drafted in 1980 during the Pinochet regime remains in force. There can be no assurance as to whether a renewal of social unrest, a new constitutional reform process, or any amendments to the Chilean Constitution implemented as a consequence of such a process, will not have a material adverse effect on our business, financial condition or results of operations. 29 Table of contents Our growth, asset quality and profitability may be adversely affected by macroeconomic and political conditions in Chile. A substantial number of our loans are to borrowers doing business in Chile. Chile’s economy has experienced significant volatility in recent decades, characterized, in some cases, by slow or regressive growth and declining investment. For example, the Chilean economy contracted 6.1% in 2020 as a result of the COVID-19 pandemic, rebounded 11.3% in 2021 and slowed to 0.3% in 2023 as a result of deteriorating economic conditions in Chile and globally, including high inflation and high interest rates. In 2025, GDP growth is expected to be 2.4% as investment levels in Chile increased among a lower interest rate environment. While the Chilean economy seems to have stabilized, the volatility experienced between 2020 and 2023 resulted in fluctuations in the levels of deposits and in the relative economic strength of various segments of the economies to which we lend. The Chilean economy may not continue to grow at similar rates as in the past or future developments may negatively affect Chile’s overall levels of economic activity. Negative and fluctuating economic conditions, such as slowing or negative growth and a changing interest rate and inflationary environment, impact our profitability by causing lending margins to decrease and credit quality to decline and leading to decreased demand for higher margin products and services. Even though Chile’s sovereign rating remains at an investment grade level, negative and fluctuating economic conditions in Chile could also result in government defaults on public debt. This could affect us in two ways: directly, through portfolio losses, and indirectly, through instabilities that a default in public debt could cause to the banking system, particularly since commercial banks’ exposure to government debt is high in Chile. Our revenues are also subject to deterioration due to unfavorable political and diplomatic developments, social instability, international conflicts, and changes in governmental policies, including expropriation, nationalization, international ownership legislation, sanctions and trade restrictions, interest-rate caps and tax policies. Any future fluctuation in oil prices may give rise to volatility in the global financial markets and further economic instability in oil-importing countries, such as Chile. In addition, the ability of borrowers in or exposed to the oil sector has been and may be further adversely affected by such price fluctuations. Any future fall in commodity prices, such as copper, cellulose, fruit, wine, lithium and salmon prices, could have a material adverse effect on the Chilean economy, which could in turn have a material adverse effect on our financial condition and operations. Our growth, asset quality and profitability may be adversely affected by volatile macroeconomic and political conditions in Chile. Any material change to United States trade policy with respect to Chile could have a material adverse effect on the economy, which could in turn materially harm our financial condition and results of operations. Portions of our loan portfolio are subject to risks relating to force majeure events and any such event could materially adversely affect our operating results. Chile lies on the Nazca tectonic plate, making it one of the world’s most seismically active regions. Our financial and operating performance may be adversely affected by force majeure events, such as natural disasters, particularly in locations where a significant portion of our loan portfolio is composed of residential mortgage and 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 the economy of the affected region. 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. As of the date hereof, we cannot predict whether other tax reforms will be enacted in the future, which could have a material adverse effect on our results of operations. Please see “Item 10—Additional information—E. Taxation” for further information regarding the impact of these tax reforms on ADR holders. 30 Table of contents 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. A deterioration of the global economic, political, social and financial environment could have a material adverse impact on the financial sector, affecting our operating results, financial position and prospects. 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. In addition, growing protectionism and trade tensions could intensify and negatively impact our customers. The U.S. government has introduced significant changes in trade policies, including the imposition of a 10% baseline "reciprocal" tariffs on most imports and nations (including Chile) and higher country-specific tariffs for certain nations with which it has significant trade imbalances. Additionally, the U.S. has threatened to impose higher sanctions on certain nations in certain circumstances. This has led to certain U.S. trading partners announcing reciprocal tariffs (and other actions) in response, leading to increased protectionism and trade tensions across the world, as well as to a depreciation of the U.S. dollar. The continuation, pause or escalation of tariffs and other trade restrictions, the continued depreciation of the U.S. dollar and other non-trade-related measures or policies of the U.S. government, could further impact international trade relations, investment flows and supply chains significantly, resulting in continued market volatility and a reduction in global growth, intensifying concerns over the global macroeconomic environment, inflation and the potential for a recession. Any of the foregoing could have a material adverse effect on our business, results of operations, financial condition and prospects and any restrictions or limitations to Chilean exports to the United States as a consequence of the factors described above could have a material adverse effect on our business, results of operations, financial condition and prospects. Lastly, recent events in Venezuela, which ultimately led to the removal and arrest of President Nicolas Maduro by the U.S. government, could have significant political and economic consequences in the region. The U.S.’s intervention in Venezuela has faced a lot of criticism worldwide, including from many countries in Latin America, and it is uncertain whether such intervention could lead to the deterioration of the U.S.’s relations with other countries in the region, including Chile. Scenarios of political tensions and instability throughout the world stemming from a variety of factors, such as heightened polarization and political interference, fragmentation and scandals, may lead to shifting and unpredictable outcomes in political elections, legislative and policy-making efforts, social conditions, government stability and the global economy and to a progressive erosion of the rule of law in certain long-standing democracies. Furthermore, increasing public debt levels together with high interest costs may not be sustainable and could lead certain countries to face higher sovereign risk premium and sovereign debt crises. Chile also has considerable economic ties with China and Europe. In 2025, approximately 35.8% 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 12.7% of total exports to Europe in 2025. Crises and political uncertainties in these economies could also have an adverse effect on Chile, the price of our securities or our business. Approximately 13.5% 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. 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 December 31, 2025, the Bank’s foreign exposure, including counterparty risk in the derivative instruments’ portfolio, was U.S.$1720.00 31 Table of contents billion or 2,273.3% 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. A change in labor laws in Chile or a worsening of labor relations in the Bank could impact our business. As of December 31, 2025, on a consolidated basis, we had 8,526 employees, of which 74% 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. A new labor reform was passed by Congress in April 2023, which, among others, reduced the work week from 45 hours to 40 hours and established an automatic adjustment of the minimum monthly income according to changes in the Consumer Price Index (CPI) which as of January 1, 2026 was set at Ch$539,000 per month (U.S.$598 per month). 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 is set at Ch$1,030,000 (U.S.$1,144 per month). 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. 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 an employment contract on the grounds of “company’s needs” and “at the employer’s will.” The bill is currently being discussed by the lower house of the Chilean Congress. While the Bank's current collective bargaining agreement takes into account the 11 year limit to calculate severance payments, we cannot guarantee that if such law passes, our potential future obligation to make severance payments will not increase significantly, which may have a material impact on our expenses. In addition, a law has been introduced in the lower house of Congress to modify the terms of the “gratificación legal,” which consists of an annual participation of workers in the profits of the company. The new law under discussion seeks to amend the Labor Code with respect to workers’ participation in company profits. The new law proposes to amend the Labor Code to increase the “gratificación legal” distributed to workers and to change the way it is calculated. This law has been approved by the Chamber of Deputies of the Chilean Congress and is currently in the Senate with no date set for consideration. No assurances can be given as to whether the proposed law will be approved and, if approved, whether it will have a material impact on our financial condition. 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 on our business, results of operations or financial condition in the future. Our corporate disclosure may differ from disclosure regularly published by issuers of securities in other countries, including the United States. Issuers of securities in Chile are required to make public disclosures that are different from, and that may be reported under presentations that are not consistent with, disclosures required in other countries, including the United States. In particular, as a Chilean regulated financial institution, we are required to submit to the FMC on a monthly basis unaudited consolidated balance sheets and income statements, excluding any note disclosure, prepared in accordance with Chilean Bank GAAP as issued by the FMC. This disclosure differs in a number of significant respects from generally accepted accounting principles in the United States and information generally available in the United States with respect to U.S. 32 Table of contents financial institutions or IFRS. In addition, as a foreign private issuer, we are not subject to the same disclosure requirements in the United States as a domestic U.S. registrant under the Exchange Act, including the requirements to prepare and issue quarterly reports, the proxy rules applicable to domestic U.S. registrants under Section 14 of the Exchange Act or the insider reporting and short-swing profit rules under Section 16 of the Exchange Act. Accordingly, the information about us available to you will not be the same as the information available to shareholders of a U.S. company and may be reported in a manner that you are not familiar with. Risks Factors In Respect Of Our Controlling Shareholder and our ADSs Investors may find it difficult to enforce civil liabilities against us or our directors, officers and controlling persons. We are a Chilean corporation. None of our directors are residents of the United States and most of our executive officers reside outside of the United States. In addition, all or a substantial portion of our assets and the assets of our directors and executive officers are located outside of the United States. Although we have appointed an agent for service of process in any action against us in the United States, none of our directors, officers or controlling persons has consented to service of process in the United States or to the jurisdiction of any United States court. As a result, it may be difficult for investors to effect service of process within the United States on such persons. It may also be difficult for ADS holders to enforce in the United States or in Chilean courts money judgments obtained in United States courts against us or our directors and executive officers based on civil liability provisions of the U.S. federal securities laws. If a U.S. court grants a final money judgment in an action based on the civil liability provisions of the federal securities laws of the United States, enforceability of this money judgment in Chile will be subject to the obtaining of the relevant “exequatur” (i.e., recognition and enforcement of the foreign judgment) according to Chilean civil procedure law currently in force, and consequently, subject to the satisfaction of certain factors. The most important of these factors are the existence of reciprocity, the absence of a conflicting judgment by a Chilean court relating to the same parties and arising from the same facts and circumstances and the Chilean courts’ determination that the U.S. courts had jurisdiction, that process was appropriately served on the defendant and that enforcement would not violate Chilean public policy. Failure to satisfy any of such requirements may result in non-enforcement of your rights. Our controlling shareholder has a great deal of influence over our business and its interests could conflict with yours. Santander Spain controls Santander-Chile through its holdings in Teatinos Siglo XXI Inversiones S.A. and Santander Chile Holding S.A., which are controlled subsidiaries. Santander Spain has control over 67.18% of our shares. Due to its share ownership, our controlling shareholder has the ability to control us and our subsidiaries, including the ability to: •elect the majority of the directors and exercise control over our company and subsidiaries; •cause the appointment of our principal officers; •declare the payment of any dividends; •agree to sell or otherwise transfer its controlling stake in us; and •determine the outcome of substantially all actions requiring shareholder approval, including amendments of our by-laws, transactions with related parties, corporate reorganizations, acquisitions and disposals of assets and issuance of additional equity securities, if any. We operate as a stand-alone subsidiary within the Santander Group. Our controlling shareholder has no liability for our banking operations, except for the amount of its holdings of our capital stock and AT1 bond. The interests of Santander Spain may differ from the interests of our other shareholders, and the concentration of control in Santander Spain may differ from the interests of our other shareholders, and the concentration of control in Santander Spain will limit other shareholders’ ability to influence corporate matters. As a result, we may take actions that our other shareholders do not view as beneficial. 33 Table of contents Our status as a controlled company and a foreign private issuer exempts us from certain of the corporate governance standards of the New York Stock Exchange (“NYSE”), limiting the protections afforded to investors. We are a “controlled company” and a “foreign private issuer” within the meaning of the NYSE corporate governance standards. Under the NYSE rules, a controlled company is exempt from certain NYSE corporate governance requirements. In addition, a foreign private issuer may elect to comply with the practice of its home country and not to comply with certain NYSE corporate governance requirements, including the requirements that (1) a majority of the board of directors consist of independent directors, (2) a nominating and corporate governance committee be established that is composed entirely of independent directors and has a written charter addressing the committee’s purpose and responsibilities, (3) a compensation committee be established that is composed entirely of independent directors and has a written charter addressing the committee’s purpose and responsibilities and (4) an annual performance evaluation of the nominating and corporate governance and compensation committees be undertaken. Although we have similar practices, they do not entirely conform to the NYSE requirements for U.S. issuers; therefore, we currently use these exemptions and intend to continue using them. Accordingly, you will not have the same protections afforded to shareholders of companies that are subject to all NYSE corporate governance requirements. There may be a lack of liquidity and market for our shares and ADSs. Our ADSs are listed and traded on the NYSE (under the ticker “BSAC”). Our common stock is listed and traded on the Santiago Stock Exchange (under the ticker “BSANTANDER”), which we refer to as the Chilean Stock Exchange, although the trading market for the common stock is small by international standards. As of December 31, 2025, we had 188,446,126,794 shares of common stock outstanding. The Chilean securities markets are substantially smaller, less liquid and more volatile than major securities markets in the United States. According to Article 14 of the Ley de Mercado de Valores, Ley No. 18,045, or the Chilean Securities Market Law, the FMC may suspend the offer, quotation or trading of shares of any company listed on one or more Chilean stock exchanges for up to 30 days if, in its opinion, such suspension is necessary to protect investors or is justified for reasons of public interest. Such suspension may be extended for up to 120 days. If, at the expiration of the extension, the circumstances giving rise to the original suspension have not changed, the FMC will then cancel the relevant listing in the registry of securities. In addition, the Santiago Stock Exchange may inquire as to any movement in the price of any securities in excess of 10% and suspend trading in such securities for a day if it is deemed necessary. Although our common stock is traded on the Chilean Stock Exchange, there can be no assurance that a liquid trading market for our common stock will continue to exist. Approximately 32.8% of our outstanding common stock is held by the public (i.e., shareholders other than Santander Spain and its affiliates), including our shares that are represented by ADSs trading on the NYSE. A limited trading market in general and our concentrated ownership in particular may impair the ability of an ADS holder to sell in the Chilean market shares of common stock obtained upon withdrawal of such shares from the ADR facility in the amount and at the price and time such holder desires and could increase the volatility of the price of the ADSs. Chile imposes controls on foreign investment and repatriation of investments that may affect your investment in, and earnings from, our ADSs. Equity investments in Chile by persons who are not Chilean residents have been subject to exchange control regulations which may restrict the repatriation of the investments and earnings therefrom. In April 2001, the Central Bank eliminated the regulations that affected foreign investors, except that investors are still required to provide the Central Bank with information relating to equity investments and conduct such operations within Chile’s Formal Exchange Market. We cannot assure you that exchange control restrictions will not be imposed again in the future, nor can we advise you as to the duration or impact of such restrictions if imposed. Holders of ADSs are entitled to receive dividends on the underlying shares to the same extent as the holders of shares. Dividends received by holders of ADSs will be paid net of foreign currency exchange fees and expenses of the Depositary and will be subject to the Chilean withholding tax, currently imposed at a rate of 35.0% (subject to credits in certain cases). If for any reason, including changes in Chilean law, the Depositary was unable to convert Chilean pesos to U.S. dollars, investors would receive dividends and other distributions, if any, in Chilean pesos. As per the current Depositary Agreement, the foreign exchange rate applied be either (i) a published benchmark rate, or (ii) a rate determined by a third-party local liquidity provider, in each case plus or minus a spread, as applicable. The Depositary will disclose which foreign exchange rate and spread, if any, apply to such currency on the "Disclosures" page (or successor page) of ADR.com. 34 Table of contents We cannot assure you that additional Chilean restrictions applicable to holders of our ADSs, the disposition of the shares underlying them or the repatriation of the proceeds from such disposition or the payment of dividends will not be imposed in the future, nor can we advise you as to the duration or impact of such restrictions if imposed. You may be unable to exercise preemptive rights. The Ley Sobre Sociedades Anónimas, Ley No. 18,046 and the Reglamento de Sociedades Anónimas, which we refer to collectively as the Chilean Companies Law, and applicable regulations require that whenever we issue new common stock for cash, we grant preemptive rights to all of our shareholders (including holders of ADSs), giving them the right to purchase a sufficient number of shares to maintain their existing ownership percentage. Such an offering would not be possible in the United States unless a registration statement under the U.S. Securities Act of 1933 (“Securities Act”), as amended, was effective with respect to such rights and common stock or an exemption from the registration requirements thereunder were available. Since we are not obligated to make a registration statement available with respect to such rights and the common stock, you may not be able to exercise your preemptive rights in the United States. If a registration statement is not filed or an applicable exemption is not available under U.S. securities law, the Depositary will sell such holders’ preemptive rights and distribute the proceeds thereof if a premium can be recognized over the cost of any such sale. As a holder of ADSs you will have different shareholders’ rights than in the United States and certain other jurisdictions. Our corporate affairs are governed by our bylaws, and the laws of Chile, which may differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States or in certain other jurisdictions outside Chile. Under Chilean corporate law, you may have fewer and less well-defined rights to protect your interests than under the laws of other jurisdictions outside Chile. For example, under legislation applicable to Chilean banks, our shareholders would not be entitled to appraisal rights in the event of a merger or other business combination undertaken by us. Although Chilean corporate law imposes restrictions on insider trading and price manipulation, the form of these regulations and the manner of their enforcement may differ from that in the U.S. securities markets or markets in certain other jurisdictions. In addition, in Chile, self-dealing and the preservation of shareholder interests may be regulated differently, which could potentially disadvantage you as a holder of the shares underlying ADSs. Holders of ADSs may find it difficult to exercise voting rights at our shareholders’ meetings. Holders of ADSs will not be our direct shareholders and will be unable to enforce directly the rights of shareholders under our by-laws and the laws of Chile. Holders of ADSs may exercise voting rights with respect to the common stock represented by ADSs only in accordance with the deposit agreement governing the ADSs. Holders of ADSs will face practical limitations in exercising their voting rights because of the additional steps involved in our communications with ADS holders. Holders of our common stock will be able to exercise their voting rights by attending a shareholders’ meeting in person or voting by proxy. By contrast, holders of ADSs will receive notice of a shareholders’ meeting by mail from the Depositary following our notice to the Depositary requesting the Depository to do so. To exercise their voting rights, holders of ADSs must instruct the Depositary on a timely basis on how they wish to vote. This voting process necessarily will take longer for holders of ADSs than for holders of our common stock. If the Depositary fails to receive timely voting instructions for all or part of the ADSs, the Depositary will assume that the holders of those ADSs are instructing it to give a discretionary proxy to a person designated by us to vote their ADSs, except in limited circumstances. Holders of ADSs also may not receive the voting materials in time to instruct the Depositary to vote on the common stock underlying their ADSs. In addition, the Depositary and its agents are not responsible for failing to carry out voting instructions of the holders of ADSs or for the manner of carrying out those voting instructions. Accordingly, holders of ADSs may not be able to exercise voting rights, and they will have little, if any, recourse if the common stocks underlying their ADSs are not voted as requested. ADS holders may be subject to additional risks related to holding ADSs rather than shares. Because ADS holders do not hold their shares directly, they are subject to the following additional risks, among others: •as an ADS holder, you may not be able to exercise the same shareholder rights as a direct holder of ordinary shares; 35 Table of contents •we and the Depositary may amend or terminate the deposit agreement without the ADS holders’ consent in a manner that could prejudice ADS holders or that could affect the ability of ADS holders to transfer ADSs; and •the Depositary may take or be required to take actions under the Deposit Agreement that may have adverse consequences for some ADS holders in their particular circumstances. GENERAL RISK FACTORS Disclosure controls and procedures over financial and non-financial reporting may not prevent or detect all errors or acts of fraud. Disclosure controls and procedures, including internal controls, over financial and non-financial reporting (including climate-related reporting) are designed to provide reasonable assurance that information required to be disclosed by the company in reports filed or submitted under the Securities Exchange Act of 1934 (the “Exchange Act”) is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the SEC’s U.S. Securities and Exchange Commission’s rules and forms. These disclosure controls and procedures have inherent limitations, which include the possibility that judgments in decision-making can be faulty and that breakdowns can occur because of errors or mistakes. Additionally, controls can be circumvented by any unauthorized override of the controls. Consequently, our businesses are exposed to risk from potential non-compliance with policies, employee misconduct or negligence and fraud, which could result in regulatory sanctions, civil claims and serious reputational or financial harm. In recent years, several multinational financial institutions have suffered material losses due to the actions of ‘rogue traders’ or other employees. It is not always possible to deter employee misconduct and the precautions we take to prevent and detect this activity may not always be effective. Accordingly, because of the inherent limitations in the control system, misstatements due to error or fraud may occur and not be detected. Our financial statements are based in part on assumptions and estimates which, if inaccurate, could cause material misstatement of the results of our operations and financial position. The preparation of financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based upon amounts which differ from those estimates. Estimates, judgments and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected. The accounting policies deemed critical to our results and financial position, based upon materiality and significant judgments and estimates, include impairment of loans and advances, good will impairment, valuation of financial instruments, deferred tax assets –provisions and pension obligations for liabilities. If the judgment, estimates and assumptions we use in preparing our consolidated financial statements are subsequently found to be incorrect, there could be a material effect on our results of operations and a corresponding effect on our funding requirements and capital ratios. Changes in accounting standards could impact reported earnings. The accounting standard setters and other regulatory bodies periodically change the financial accounting and reporting standards that govern the preparation of our consolidated financial statements. Changes made to accounting standards can materially impact how we record and report our financial condition and results of operations, as well as affect the calculation of our capital ratios. In some cases, we could be required to apply a new or revised standard retroactively, resulting in the restatement of prior period financial statements. Various amendments were made to financial and accounting standards in 2023, 2024 and 2025. For more information about current and future developments in financial accounting and reporting standards, see Note 1(y) “Application of new and revised International Financial Reporting Standards” to our Audited Consolidated Financial Statements. We rely on recruiting, retaining and developing appropriate senior management and skilled personnel. Our continued success depends in part on the continued service of key members of our senior executive team and other key employees. The ability to continue to attract, train, motivate and retain highly qualified and talented professionals is a 36 Table of contents key element of our strategy. The successful implementation of our strategy and culture depends on the availability of skilled and appropriate management, both at our head office and in each of our business units. If we or one of our business units or other functions fails to staff its operations appropriately or loses one or more of its key senior executives or other key employees and fails to replace them in a satisfactory and timely manner, our business, financial condition and results of operations, including control and operational risks, may be adversely affected. Our ability to attract and retain qualified employees is affected by perceptions of our culture, social and corporate governance policies and management, our profile in the markets in which we operate and the professional opportunities we offer. In addition, the financial industry has and may continue to experience more stringent regulation of employee compensation, which could have an adverse effect on our ability to hire or retain the most qualified employees. If we fail or are unable to attract and appropriately train, motivate and retain qualified professionals, our business may also be adversely affected. Our business could be affected if its capital is not managed effectively or if changes limiting our ability to manage our capital position are adopted. Effective management of our capital position is important to our ability to operate our business, to continue to grow organically and to pursue our business strategy. However, in response to the global financial crisis, several changes to the regulatory capital framework have been adopted. As these and other changes are implemented or future changes are considered or adopted that limit our ability to manage our balance sheet and capital resources effectively or to access funding on commercially acceptable terms, we may experience a material adverse effect on our financial condition and regulatory capital position. We are subject to review by tax authorities, and an incorrect interpretation by us of tax laws and regulations may have a material adverse effect on us. Preparing our tax returns requires the use of estimates and interpretations of complex tax laws and regulations and is subject to review by tax authorities. We are subject to the income tax laws of Chile and certain foreign countries. These tax laws are complex and subject to different interpretations by the taxpayer and relevant governmental tax authorities, which are sometimes subject to prolonged evaluation periods until a final resolution is reached. In establishing a provision for income tax expense and filing returns, we must make judgments and interpretations about the application of these inherently complex tax laws. If the judgment, estimates and assumptions we use in preparing our tax returns are subsequently found to be incorrect, there could be a material adverse effect on our results of operations. In some jurisdictions, the interpretations of the tax authorities are unpredictable and frequently involve litigation, which introduces further uncertainty and risk as to tax expense. We engage in transactions with related parties that others may not consider to be on an arm’s-length basis. We and our affiliates have entered into several services agreements pursuant to which we render services, such as administrative, accounting, finance, treasury, legal services and others. Chilean law applicable to public companies and financial groups and institutions and our by-laws provide for several procedures designed to ensure that the transactions entered into with or among our financial subsidiaries and/or affiliates do not deviate from prevailing market conditions for those types of transactions, including the requirement that our board of directors approve such transactions. Furthermore, all significant related party transactions must be approved by the Audit Committee and the Board. These significant transactions are also reported in our annual shareholders’ meeting. Please see Note 34 to our Audited Consolidated Financial Statements and “Item 7. Major Shareholders and Related Party Transactions.” We are likely to continue to engage in transactions with our affiliates. Future conflicts of interests between us and any of our affiliates, or among our affiliates, may arise, which conflicts are not required to be and may not be resolved in our favor. 37 Table of contents

A.History and Development of the Company Overview We are the largest bank in the Chilean market in terms of loans (excluding loans held by subsidiaries of Chilean banks abroad) and the second largest bank in terms of total deposits (excluding deposits held by subsidiaries of Chilean banks aboard). As of December 31, 2025, we had total assets of Ch$68,147,280 million (U.S.$68.7 billion), outstanding loans at amortized cost, net of allowances for loan losses and including interbank loans of Ch$40,932,880 million (U.S.$41.3 billion), total deposits of Ch$30,569,373 million (U.S.$30.8 billion) and shareholders’ equity of Ch$5,616,359 million (U.S.$5.7 billion). As of December 31, 2025, we employed 8,526 people. We have a leading presence in all the major business segments in Chile, and a large distribution network with national coverage spanning across all the country and a leading digital onboarding platform for new clients. We offer unique transaction capabilities to clients through our 229 branches and 2,055 ATMs. Our headquarters are in Santiago, and we operate in every major region of Chile. We provide a broad range of commercial and retail banking services to our customers, including Chilean peso and foreign currency denominated loans to finance a variety of commercial transactions, trade, foreign currency forward contracts and credit lines and a variety of retail banking services, including mortgage financing. We seek to offer our customers a wide range of products while providing high levels of service. In addition to our traditional banking operations, we offer a variety of financial services, including financial leasing, financial advisory services, mutual fund management, securities brokerage, insurance brokerage and investment management. The legal predecessor of Santander-Chile was Banco Santiago (“Santiago”). Old Santander-Chile was established as a subsidiary of Santander Spain in 1978. On August 1, 2002, Santiago and Old Santander Chile merged, whereby the latter ceased to exist and Santander-Chile (formerly known as Santiago) being the surviving entity. Our principal executive offices are located at Bandera 140, 20th floor, Santiago, Chile. Our telephone number is +562-320-2000 and our website is www.santander.cl.

Relationship with Grupo Santander We believe that our relationship with our controlling shareholder, Grupo Santander, offers us a significant competitive advantage over our peer Chilean banks. Grupo Santander, our parent company, is one of the largest financial groups in Brazil and the rest of Latin America, in terms of total assets measured on a regional basis. It is the largest financial group in Spain and is a major player elsewhere in Europe, including the United Kingdom, Poland and Portugal. Through Santander Consumer, it also operates a leading consumer finance franchise in the United States, as well as in Germany, Italy, Spain, and several other European countries. Openbank, a digital banking subsidiary of Grupo Santander, operates in Spain, Germany, Portugal, Netherlands, United States and Mexico: Our relationship with Grupo Santander provides us with access to the group’s client base, while its multinational focus allows us to offer international solutions to our clients’ financial needs. We also have the benefit of selectively borrowing from Santander Spain’s product offerings in other countries, as well as of its know-how in systems management. We believe that our relationship with Santander Spain will also enhance our ability to manage credit and market risks by adopting policies and knowledge developed by Grupo Santander. In addition, our internal auditing function has been strengthened as a result of the addition of an internal auditing department that concurrently reports directly to our Audit Committee and the audit committee of Santander Spain. We believe that this structure leads to improved monitoring and control of our exposure to operational risks. Grupo Santander’s support of Santander-Chile includes the assignment of managerial personnel to key supervisory areas of Santander-Chile, such as risks, auditing, accounting and financial control. Santander-Chile does not pay any management fees to Santander Spain in connection with these support services. 38 Table of contents B.Business Overview We have 229 branches of which: (i) 126 are traditional full product and transactional branches operated under the Santander brand name; (ii) 94 are WorkCafé or WorkCafé Espresso branches, which are high-tech digital branches; (iii) and the remaining 9 branches are Select branches for affluent customers. We divide our clients into the following groups: (i) Retail banking, (ii) Wealth Management, (iii) Middle-market, (iv) Corporate Investment Banking and (v) Corporate Activities (“Other”). The Bank has the reportable segments noted below see “Segmentation Criteria” for further information. Retail Banking This segment consists of individuals, excluding high-net worth clients, and small to medium-sized entities (SMEs) with annual sales less than UF400,000 (U.S.$17.6 million). This segment gives customers a variety of services, including consumer loans, credit cards, auto loans, commercial loans, foreign exchange, mortgage loans, debit cards, checking accounts, savings products, securities brokerage, and insurance brokerage. Additionally, the SME clients are offered government-guaranteed loans, foreign trade services, leasing, factoring, and transactional services. Wealth Management This segment comprises the Asset Management, Insurance and Private Banking businesses. The Santander Insurance business offers both personal and corporate protection products, health insurance, life insurance, travel insurance, savings products, personal protection, automobile insurance, leasing, guarantees, unemployment insurance, among others. For high net worth clients, Santander Private Banking offers everything from transactional products and services (credits, cards, foreign trade, brokerage) to sophisticated products and services such as international investment accounts, structured funds, alternative investment funds, wealth management and open architecture. Middle-market This segment includes companies with annual sales exceeding UF400,000 (US$17.6 million) without a cap (for specialized industries in the Santiago Metropolitan Region, annual sales exceeding 100,000 UF (US$4.4 million) without a cap). This segment also encompasses institutional organizations such as universities, government agencies, municipalities, regional governments, and real estate companies undertaking projects for third-party sales, as well as all construction companies with annual sales exceeding UF 100,000 (US$4.4 million) without a cap. A wide variety of products are offered to this segment, including commercial loans, leasing, factoring, foreign trade, credit cards, mortgage loans, current accounts, transactional services, treasury services, financial consulting, savings products, mutual funds and insurance. In addition companies in the real estate sector are offered specialized services for the financing of mainly residential projects, with the intention of increasing the sale of mortgage loans. Corporate Investment Banking (“CIB”) This segment services multinational firms with annual sales exceeding EUR 500 million (USD 585 million), EBITDA over EUR 150 million (USD 175.5 million), and assets exceeding EUR 1 billion (USD 1.17 billion). For financial institutions, the requirement is assets greater than Ch$10 trillion (US$11.1 billion) This segment offers a wide variety of products, including commercial loans, leasing, factoring, foreign trade, credit cards, mortgage loans, current accounts, transactional services, treasury services, financial consulting, investment banking, savings products, mutual funds and insurance. This segment includes the Treasury Division, which provides sophisticated financial products mainly to companies in the Retail Banking and Middle-market areas. Products include short-term financing and deposits, brokerage services, derivatives, securitization and other products tailored to the needs of clients. The Treasury area also handles the intermediation of positions, as well as the company's own investment portfolio. Corporate Activities (“Other”) This segment mainly includes our Financial Management Division, which develops global management functions, including managing inflation rate risk, foreign currency gaps, interest rate risk and liquidity risk. Liquidity risk is managed mainly through wholesale deposits, debt issuances and the Bank’s available-for-sale portfolio. This segment also manages capital allocation by unit. These activities, with the exception of our inflation gap, usually result in a negative contribution to income. 39 Table of contents In addition, this segment encompasses all the intra-segment income and all the activities not assigned to a given segment or product with customers. The segments’ accounting policies are those described in the summary of accounting policies. 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 tables below show the Bank’s results by reporting segment for the year ended December 31, 2025, in addition to the corresponding balances of loans and accounts receivable from customers: For the year ended December 31 2025 Loans and accounts receivable atamortizedcost(1) Deposits and other demand liabilities Net interest income Net fee and commission income Net income from financial operations Provision for loan losses Support expenses(2) Other op.income and expenses (5) Net income before taxes Income tax Net income (In millions of Ch$) Retail 31,225,378 13,094,059 1,642,104 503,186 64,292 (498,572) (744,059) (77,593) 889,358 (211,987) 677,371 Wealth Management & insurance 924,692 3,177,991 59,789 30,019 4,236 (2,870) (32,037) (1,976) 57,161 (13,963) 43,198 Middle-Market 6,178,983 4,262,866 334,660 52,921 22,154 (74,190) (45,074) (3,856) 286,615 (78,709) 207,906 CIB 2,139,201 7,313,098 211,915 47,404 143,503 4,269 (103,287) (2,654) 301,150 (83,216) 217,934 Corporate Activity & others 464,626 2,721,359 (261,785) (37,699) 21,597 (3,950) (14,956) 7,924 (288,869) 180,513 (108,356) Total 40,932,880 30,569,373 1,986,683 595,831 255,782 (575,313) (939,413) (78,155) 1,245,415 (207,362) 1,038,053 (1)Corresponds to loans and accounts receivable at amortized cost under IFRS 9, without deducting their allowances for loan losses.

Permitted subsidiaries include leasing and factoring companies, payment and card processors, brokerage firms, fund managers, custodial and other financial service entities, as well as operational support companies such as IT or back-office services. Chilean banks are not allowed to own insurance companies and may only own insurance brokerage subsidiaries, which must operate with full functional and governance separation. All subsidiaries require prior FMC authorization, are subject to consolidated supervision and Basel III capital rules, and banks are expressly prohibited from owning commercial, industrial, or other non-financial businesses. For the twelve–month period ended December 31, 2025, our subsidiaries collectively accounted for 2.1% of our total consolidated assets. The following companies are considered entities controlled by the Bank and are therefore within the scope of consolidation: Percent ownership share As of December 31, Name of the Subsidiary Main Activity Place of incorporation and operation 2025 2024 2023 Direct Indirect Total Direct Indirect Total Direct Indirect Total % % % % % % % % % Santander Corredora de Seguros Limitada Insurance brokerage Santiago, Chile 99.75 0.01 99.76 99.75 0.01 99.76 99.75 0.01 99.76 Santander Corredores de Bolsa Limitada Financial instruments brokerage Santiago, Chile 50.59 0.41 51.00 50.59 0.41 51.00 50.59 0.41 51.00 Santander Asesorias Financieras Limitada Securities brokerage Santiago, Chile 99.03 - 99.03 99.03 - 99.03 99.03 - 99.03 Santander S.A.

The company Bansa Santander S.A. was included in the consolidation perimeter until May 2024. The Bank did not have an ownership percentage of Bansa Santander S.A., which was consolidated as a consequence of being controlled by the management of Santander Consumer Chile S.A. During the months of April and May of 2024, Bansa Santander S.A. and Santander Investments Chile Limitada made a series of modifications to the financing agreements existing between them, as a result of which the shareholders of Bansa Santander S.A. also granted Santander Investments Chile Limitada the power to appoint one of the three members of its Board of Directors. Therefore, as of May 2024, Santander Consumer Finance Limitada lost control of Bansa Santander S.A., having to exclude this company from its consolidation scope. Pagonxt Payments Chile SpA was included in the consolidation perimeter until December 2024. The Bank did not have an ownership percentage in Pagonxt Payments Chile SpA, which was consolidated based on the fact that it was controlled by the management of the Bank. The company PagoNxt Payments Chile SpA in January 2025 signed an agreement with the related entity Santander Global Technology and Operations Chile Limitada to transfer its assets, contracts, and employees. As a result, the Bank no longer controlled this entity and PagoNxt Payments Chile SpA is no longer consolidated. 41 Table of contents 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 million, and (ii) the execution of an agreement between us and Getnet, with a value that ranges from Ch$55,465 million and Ch$79,999 million 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. On January 27, 2026, an Extraordinary Shareholders’ Meeting of Banco Santander-Chile was held, at which the shareholders resolved to approve the acceptance of the offer made by Getnet Payments, S.L. to Banco Santander-Chile and Santander Asesorías Financieras Limitada for the purchase of 49.99% of the shares of the subsidiary Sociedad Operadora de Tarjetas de Pago Santander Getnet Chile S.A., in the terms previously stated. The Bank also has significant influence over the following entities: Place of Incorporation and operation Percentage of ownership share as of December 31, 2025 2024 2023 Associates Main activity (in %) Redbanc S.A.

Administration of the infrastructure for the financial market of derivative instruments Santiago, Chile 12.48 12.48 12.48 In 2018, the Bank announced it was selling its share participation on Redbanc S.A. and Transbank S.A. Accordingly, we classified those investments in accordance to IFRS 5 “Non-current Assets Held for Sale and Discontinued Operations” as investments available for sale. Since no potential buyers were identified, the Bank has reclassified those investments as investments in associates and accounted using the equity method. The Bank continues to be committed to the sale plan for these assets, actively seeking potential buyers and continuing its plans to develop its own acquiring network, as evidenced by the recent creation of a payment card operating company. In the case of Cámara Compensación de Pagos Alto Valor S.A., Banco Santander-Chile has a representative on the Board of Directors. As per the definition of associates, the Bank has concluded that it exerts significant influence over this entity. In 2024, the Bank sold a stake of 1.28% and reduced its participation to 13.72% in this company. In the case of Servicios de Infraestructura de Mercado OTC S.A., the Bank actively participates, through its executives, in the administration and in the process of organization, which is why the Administration has concluded that it exerts significant influence over it. 42 Table of contents Competition Overview The Chilean financial services market consists of a variety of largely distinct sectors. The most important sector, commercial banking, includes a number of privately-owned banks and one public-sector bank, Banco del Estado de Chile (which operates within the same legal and regulatory framework as the private sector banks). The private-sector banks include local banks and a number of foreign-owned banks operating in Chile. The Chilean banking system is comprised of 17 banks, including one public-sector bank. The six largest banks accounted for 85.4% of all outstanding loans by Chilean financial institutions as of December 31, 2025 (excluding assets held abroad by Chilean banks). The Chilean banking system has experienced increased competition in recent years, largely due to consolidation in the industry and new legislation. In 2025, the merger between Banco BICE and Banco Security was completed, creating the 7th largest bank in Chile in terms of loan portfolio. In 2025 Tanner Digital Bank began its operations as a new bank in Chile servicing SMEs and Tenpo, a digital consumer bank, is expected to begin operating in 2026. We also face competition from non-bank and non-finance competitors, principally department stores, credit unions and cajas de compensación (private, non-profitable corporations whose aim is to administer social welfare benefits, including payroll loans, to their members) with respect to some of our credit products, such as credit cards, consumer loans and insurance brokerage. In addition, we face competition from non-bank finance competitors, such as leasing, factoring and automobile finance companies, with respect to credit products, and mutual funds, pension funds and insurance companies, with respect to savings products. Our subsidiary, Getnet, also competes against non-banks, such as MercadoPago, in the acquiring market. Currently, banks continue to be the main suppliers of leasing, factoring and mutual funds, and the insurance sales business has grown rapidly. All the competition data in the following sections is based on Chilean Bank GAAP. The following tables set out certain statistics comparing our market position to that of our peer group, defined as the six largest banks in Chile in terms of total loans as of December 31, 2025 or the latest date available (excluding assets held by Chilean banks abroad).

The main authorities that regulate financial institutions in Chile are the FMC and the Central Bank. Chilean banks are primarily subject to the General Banking Law, and to the extent inconsistent with this law, secondarily to the provisions of the Chilean Companies Law applicable to public corporations, with the exception of certain provisions that expressly are excluded. The modern Chilean banking system dates back to 1925 and has been characterized by periods of extensive regulation and government intervention, as well as periods of deregulation. The most recent period of deregulation began in 1975 and culminated in the adoption of a series of amendments to the General Banking Law. This law was amended in 2001 to grant additional powers to banks, including general underwriting powers for new issues of certain debt and equity securities and the power to establish subsidiaries to engage in activities related to banking, such as brokerage, investment advisory and mutual fund services, investment fund management, factoring, securitization products and financial leasing services. In January 2019, amendments to the General Banking Law were introduced by Law 21,130, which modernized Chile’s banking legislation by adopting capital and resolution standards in line with Basel Committee requirements. More recently, the Fintech Law, in addition to introducing regulations related to the SFA, introduced relevant amendments to the General Banking Law, granting the FMC authority to establish rules of attention to customers of the banking industry and regulations applicable to banking subsidiaries. Finally, Law 21,694, published in September 2024, establishes certain additional exceptions to banking secrecy, stipulating that entities that have a legitimate interest under the law may also access information subject to banking secrecy. The Central Bank The Central Bank is an autonomous legal entity created by the Chilean Constitution. It is subject to the Chilean Constitution and its own ley orgánica constitucional, or organic constitutional law. To the extent not inconsistent with the Chilean Constitution or the Central Bank’s organic constitutional law, the Central Bank is also subject to private sector laws (but in no event is it subject to the laws applicable to the public sector). It is directed and administered by a Board of Directors composed of five members designated by the President of Chile, subject to the approval of the Chilean Senate. The legal purpose of the Central Bank is to maintain the stability of the Chilean peso, that is, to keep inflation low and stable over time. The Central Bank is also responsible for the orderly functioning of Chile’s internal and external payment systems. The Central Bank’s powers include setting reserve requirements, regulating the amount of money and credit in circulation, establishing regulations and guidelines regarding finance companies, foreign exchange (including the Formal Exchange Market) and banks’ deposit-taking activities. According to Article 132 of the General Banking Law, demand deposits and other obligations with unconditional withdrawal rights are 100% guaranteed by the Central Bank of Chile in the event of forced liquidation of a bank, regardless of whether the depositors are natural or legal persons. Financial Market Commission The Comisión para el Mercado Financiero or Financial Market Commission (FMC) is the sole supervisor for the Chilean financial system overseeing insurance companies, companies with publicly traded securities, credit unions, credit card and prepaid card issuers, and, as of June 1, 2019, banks. This commission is responsible for ensuring the proper functioning, development and stability of the financial market, facilitating market agents' participation and defending public faith in the financial markets. To do so, it must maintain a general and systemic vision of the market, considering the interests of investors and policyholders. Likewise, it shall be responsible for ensuring that the persons or entities audited, from their initiation until the end of their liquidation, comply with the laws, regulations, statutes and other provisions that govern them. The Commission oversees a Council, which is composed of five members, who are appointed and are subject to the following rules: •A commissioner appointed by the President of Chile, of recognized professional or academic prestige in matters related to the financial system, which will have the character of president of the FMC. 48 Table of contents •Four commissioners appointed by the President of Chile, from among persons of recognized professional or academic prestige in matters related to the financial system, by supreme decree issued through the Ministry of Finance, after ratification of the Senate by the four sevenths of its members in exercise, in session specially convened for that purpose. The Council’s responsibilities include regulation, sanctioning and the definition of general supervision policies. In addition, there will be a prosecutor in charge of investigations and the Chairman will be responsible for supervision. The FMC will act in coordination with the Central Bank. In January 2019, Law 21,130, which modernized the banking legislation contained in the General Banking Law and amended Law 21,000 (among others), was published in the Official Gazette. The law modernizes Chilean banking regulation in order to comply with Basel III practices and provisions. The law provides for stronger banking capital and reserves requirements in accordance with Basel III guidelines. The FMC now has the faculty to determine the risk weighting of assets through a standardized model to be approved by the FMC or banks can implement their own methodology, subject to approval by the FMC. The law also imposes limitations on dividend distributions and puts in place intervention mechanisms in the event of insolvency. The regulator examines all banks from time to time, generally at least once a year. Banks are also required to submit their financial statements monthly to the FMC, and the banks’ financial statements are published at least four times a year in a newspaper with countrywide coverage. In addition, banks must provide extensive information about their operations at various periodic intervals to the FMC. A bank’s annual financial statements and the opinion of its independent auditors must also be submitted to the FMC. Any person wishing to acquire, directly or indirectly, 10.0% or more of the share capital of a bank must obtain the prior approval of the FMC. Absent such approval, the acquirer of shares so acquired will not have the right to vote. The FMC may only refuse to grant its approval, based on specific grounds set forth in the General Banking Law. According to Article 35 bis of the General Banking Law, the prior authorization of the regulator is required for: •the merger of two or more banks; •the acquisition of all or a substantial portion of a bank’s assets and liabilities by another bank; •the control by the same person, or controlling group, of two or more banks; or •a substantial increase in the existing control of a bank by a controlling shareholder of that bank. The intended purchase, merger or expansion may be denied by the regulator with an accompanying resolution recording the specific reasons for denial and with the agreement of a majority of the Board of Directors of the Central Bank. Pursuant to the regulations of the FMC, the following ownership disclosures are required: •a bank is required to inform the FMC of the identity of any person owning, directly or indirectly, 5.0% or more of such banks’ shares; •holders of ADSs must disclose to the Depositary the identity of beneficial owners of ADSs registered under such holders’ names; •the Depositary is required to notify the bank as to the identity of beneficial owners of ADSs which such Depositary has registered and the bank, in turn, is required to notify the FMC as to the identity of the beneficial owners of the ADSs representing 5.0% or more of such banks’ shares; and •bank shareholders who individually hold 10.0% or more of a bank’s capital stock and who are controlling shareholders must periodically inform the FMC of their financial condition. 49 Table of contents Limitations on Types of Activities Chilean banks can only conduct those activities allowed by the General Banking Law: making loans, accepting deposits and, subject to limitations, making investments and performing financial services. Investments are restricted to real estate for the bank’s own use, gold, foreign exchange and debt securities. Through subsidiaries, banks may also engage in other specific financial service activities such as securities brokerage services, equity investments, securities, mutual fund management, investment fund management, financial advisory and leasing activities. Subject to specific limitations and the prior approval of the FMC and the Central Bank, Chilean banks may own majority or non-controlling interests in foreign banks. Deposit Insurance The General Banking Law protects certain depositors by providing government deposit insurance. The guarantee only extends to certain time deposits and savings accounts held by natural persons with a maximum value of UF400 per person (Ch$15.9 million or U.S.$17,643 as of December 31, 2025) per calendar year in the entire financial system and a maximum of UF200 per person per bank (Ch$7.9 million or U.S.$8,822 as of December 31, 2025. Governmental deposit insurance does not cover time deposits or savings account balances for legal entities (including for-profit and non-profit institutions or companies). Demand deposits and other obligations with unconditional withdrawal rights are 100% guaranteed by the Central Bank of Chile in the event of forced liquidation of a bank, regardless of whether the depositors are natural or legal persons. Reserve Requirements 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). For purposes of calculating the reserve obligation, banks are authorized to deduct daily from their foreign currency denominated liabilities, the balance in foreign currency of certain loans and financial investments held outside of Chile, the most relevant of which include: •cash clearance account, which should be deducted from demand deposit for calculating reserve requirement; •certain payment orders issued by pension providers; and •the amount set aside for “technical reserve” (as described below), which can be deducted from reserve requirement. 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 they 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% “technical reserve” against them: demand deposits, deposits in checking accounts, or obligations payable on sight incurred in the ordinary course of business, and in general all deposits unconditionally payable immediately, but excluding interbank demand deposits. As of December 31, 2025, the Bank was not required to maintain this reserve. Minimum Capital On October 9, 2020, the FMC published the regulations on regulatory capital to comply with regulatory capital regulation in accordance with Basel III and General Banking Law. The new regulation became effective on December 1, 2021 and is being gradually implemented and adjusted to be fully in place by December 1, 2025. Pursuant to the proposed regulation, there are three levels of capital: core capital level 1 or CET1 (core capital), additional tier I capital or AT1 (perpetual bonds and preferred stock) and Tier 2 or T2 capital (subordinated bonds and voluntary provisions). Regulatory capital is composed of the sum of CET1, AT and T2 after making some deductions, mainly for intangible assets, hybrid securities issued by foreign subsidiaries, partial deduction for deferred taxes and some reserve and profit accounts. The minimum total regulatory capital is 8% of risk-weighted assets, which includes credit, market, and operational risk. This minimum increases in line with the size, complexity and solvency of a bank and the FMC’s assessment of a bank’s management. 50 Table of contents According to Chilean regulations regulatory core capital must be as a minimum 4.5% of risk weighted assets (RWA) of a Bank. In addition, and to avoid restrictions on dividend payments, a bank must have an additional conservation buffer of 2.5% of RWA. The conservation buffer will be gradually phased in by 2025 and must be comprised of core capital. The Central Bank may set an additional CCyB of up to 2.5% of risk-weighted assets in agreement with the FMC, also comprised of core capital. At the Central Bank’s Financial Policy Meeting, held in the first half of 2023, the Board of the Central Bank of Chile agreed to activate the CCyB for banks, setting it at 0.5% of risk-weighted assets, which must be implemented by May 2024. In November 2024, the Central Bank further updated the framework for determining the CCyB with the objective of moving towards what the Central Bank defined as the "neutral level" for this buffer, which was set at 1% of risk-weighted assets. The Central Bank's Financial Policy Committee will define the transition process towards this neutral level, which will be achieved gradually, only once convergence to Basel III standards is completed in December 2025. In particular, the initiation of the convergence toward the "neutral level" will be evaluated during the first Financial Policy Meeting of the year 2026. This decision will be adopted as macro-financial conditions allow, taking into account a timeframe of at least one year for its gradual implementation. This framework also sets the steps for loosening the CCyB if credit conditions warrant it. Risk scenario CCyB Level Elements to Consider Standard Risk CCyB at its Neutral level - Bank balance sheets show activity and results within normal ranges. - Credit markets functioning normally. - Asset price dynamics aligned with fundamentals. Significant Increase in Systemic Risk CCyB increases exceptionally above Neutral - Credit growth significantly detached from fundamentals. - Household and corporate leverage at very high levels. - Asset overvaluation. - External risks far exceeding usual levels. - Bank balance sheets showing unusually high activity and results. Materialization of Systemic Risk or Unexpected Shock CCyB is fully or partially reduced to a level below Neutral - Adverse shock to the economy from internal or external sources. - Significant reduction in financial asset prices. - Difficulties in access to financing for households and businesses. - Banking sector shows weaknesses, including expectations of significant losses and increased cost of capital. Recovery CCyB remains reduced below Neutral level or at zero - Beginning of recovery in the economy and banking sector. - Balance sheets, risk indicators, and bank profitability in the process of recovery. - Credit supply showing signs of recovery. - Asset prices starting to align with fundamentals. Reconstruction of CCyB CCyB gradually increases toward Neutral level as recovery consolidates - Signs of consolidated economic recovery. - Bank balance sheets, risk indicators, and profitability recovered. - Banks able to absorb capital impacts without relevant systemic risks. On November 2, 2020, the FMC published updated guidelines regarding the identification and core capital charge for banks considered Systemically Important Banks (“SIBs”). The FMC, in agreement with the Central Bank, also imposed additional capital requirements for SIBs of between 1-3.5% of risk-weighted assets. This additional capital was gradually phased in by 25% beginning in December 2021 until December 2025. There are a total of four factors that are weighted to reach a market share: 1.Size (weighted at 30%): Includes total assets consolidated in the domestic market. 51 Table of contents 2.Domestic interconnection (weighted at 30%): Includes assets and liabilities with financial institutions (banks and non-banks) and assets in circulation in the Chilean financial market (equity and fixed income). 3.Domestic substitution (weighted at 20%): Includes the share in local payments, assets in custody, deposits and loans. 4.Complexity (weighted at 20%): Includes factors that could lead to greater difficulties regarding costs and/ or time for the orderly resolution of the Bank. These include the notional amount of OTC derivatives, inter-jurisdictional assets and liabilities and available-for-sale assets. The minimum amount of the sum of the factors to be considered systemic is 1000 bp, equivalent to a weighted participation of 10% of all four factors. The core capital additional charge depends on the size of the total factor, as set out in the table below: Systemic Level Range (bp) Core capital additional charge (% of risk-weighted assets) I 1000-1300 1.0%-1.25% II 1300-1800 1.25%-1.75% III 1800-2000 1.75%-2.5% IV >=2000 2.5%-3.5% The Central Bank may also require for a SIB: (1) the addition of up to 2% to the core capital to a bank’s total assets ratios; (2) a reduction in the technical reserve requirement trigger from 2.5 times regulatory capital to 1.5 times regulatory capital; and/or (3) a reduction in the interbank loan limit to 20% of regulatory capital of any SIB. Under this framework, we are classified as a Level II SIB with a requirement of maintaining 1.5% of RWA as core capital to fulfill this requirement. Banks must also have at least 1.5% of RWA in Additional Tier 1 capital (AT1), either in the form of preferred shares or perpetual bonds, both of which may be convertible to common equity. The maximum amount of AT1 is set at 1/3 of core capital. As a temporary measure, the FMC permits banks to fulfill their minimum AT1 requirement with Tier II instruments. In October 2021, the Bank issued an AT1 perpetual bond for U.S.$700 million with no fixed maturity and not redeemable before five years from the date of issuance. The bond is convertible to shares if the banks CET1 ratio falls below 5.125% in line with the FMC conditions and requirements for the issuance of perpetual bonds and preferred equity. Tier 2 capital is now set at a minimum of 2% of RWA. Tier 2 includes subordinated bonds and up to the equivalent of 50% of core capital can be considered Tier 2. Additional provision in accordance with the rules of General Banking Law can also be considered Tier 2 in amount up to 1.25% of RWA. The General Banking Law also incorporates Pillar II capital requirements to ensure adequate risk management. This pillar's objective is to ensure that banks maintain capital levels consistent with their risk profile and business model and encourages the development and use of appropriate processes to monitor and manage their risks. Pillar II also granted the regulators the power to impose greater capital requirements because of deficient evaluations of a bank’s internal capital adequacy assessment process (ICAAP), which should consider a bank’s risk profile and a strategy to sustain adequate levels of capital, even under stress scenarios. ICAAP is a process through which a bank evaluates its capital needs in relation to its risk profile, strategic objectives, and operating environment and is required by the FMC. Pillar II also focuses on risks not considered in Pillar I such as reputational risks, concentration risks, liquidity risks and interest rate risks. The FMC, with at least four votes from the Council of the FMC, will have the power to impose additional regulatory capital demands of up to 4% of risk-weighted assets, either Tier I or Tier II, if it determines that the previous capital levels and buffers are not enough for a particular financial institution. On April 11 2025, the FMC resolved to establish a Pilar II requirement of 25 basis points of total capital for Banco Santander Chile with an initial tranche of 12.5 basis points constituted by June 30, 2025. On January 16, 2026 and following the completion of the FMC's annual supervisory process, the FMC determined that the 0.125% Pilar II requirement for Santander Chile was sufficient. Every year the FMC will perform an annual capital adequacy assessments analysis as part of its supervisory process, which could result in a higher Pilar II capital requirement. Therefore, we cannot assure you that our minimum capital requirements will not be impacted by new regulatory Pilar II thresholds in the future. 52 Table of contents On December 12, 2023, the FMC published for public comment on proposals 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 January 17, 2024, the FMC stated that banks that had a level of market risk of the banking book greater than 15% of CET1 would have to meet an additional capital requirement under Pillar II guidelines. 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 II Requirement and Pillar II 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 II 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 Chilean banking industry in the future, including us. Therefore, we cannot guarantee that our profitability will not be impacted by actions we may be required to take in order to fulfill new regulatory capital requirements which may be established by the FMC in the future. In 2023, the FMC introduced Pillar III requirements for Chilean banks. The objective of the Pillar III standard is to give the public more transparency to better evaluate the capital situation of each entity. To do this, banking institutions must publish an independent document, referring exclusively to this pillar, which must offer readers a source of prudential parameters, updated according to the periodicity indicated, with all the information disclosure requirements indicated by the regulator. The following table sets forth the regulatory capital demands under the General Banking Law: Minimum capital requirements: Basel III, previous GBL and new requirements Capital categories General Banking Law (% over risk weighted assets) (1) Core capital 4.5% (2) Additional Tier 1 Capital (AT1) Minimum 1.5% up to 1/3 of core capital (3) Total Tier 1 Capital (1+2) 6.0% (4) Tier 2 Capital Minimum 2.0% with subordinated bonds up to 50% of core capital and additional provisions up to 1.25% of RWAs (5) Total Regulatory Capital (3+4) 8.0% (6) Conservation Buffer 2.5% CET1 (7) Total Equity Requirement (5+6) 10.5% (8) Counter Cyclical Buffer up to 2.5% CET1. Currently set at 0.5% (9) SIB Requirement Between 1 – 3.5% CET1 (10) Pillar II Up to 4% CET1 or Tier 2 Risk Weightings The Basel Committee on Banking Supervision (BCBS) defines credit risk (CR) as the risk that a debtor or bank counterparty does not meet its obligations in accordance with the agreed terms. Credit risk is the most relevant in the 53 Table of contents Chilean banking industry. The prior mechanism estimated Risk Weighted Assets by Credit Risk (RWCR) using a methodology based on the Basel I standard. The standard method with Basel III standards is more advanced, since it has categories that depend on the type of counterparty and different risk factors. These categories are not based on accounting criteria, but rather on the underlying risk. Thus, all exposures that have mortgage guarantees, for example mortgage loans for housing, have a different treatment from those exposures not guaranteed by a mortgage. Additionally, in the case of mortgage-backed exposures, there are different types of treatment depending on the type of real estate and whether the obligations are paid with income generated by the property itself. The new framework also allows the use of internal methodologies, subject to compliance with minimum requirements. The new standards for weighing credit risk include the possibility of reducing RWCR when considering credit risk mitigators, such as compensation agreements, guarantees and other compensations. The Basel Committee on Banking Supervision (BCBS) defines operational risk (OR) as the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. This definition includes legal risk but excludes strategic and reputational that a debtor or bank counterparty does not meet its obligations in accordance with the agreed terms. In order to estimate the operational risk coefficient, two factors are considered: 1.The business indicator component (BIC): A component that considers interest income, interest earning assets, dividend income, financial transactions, fees, and other operational income and expenses. These are then multiplied by a marginal coefficient. 2.Internal Loss Multiplier (ILM): This component is based on 10 years of historical operational losses, or at least five years in some special cases. BCBS defines market risk (MR) as the risk of losses arising from movements in market prices. The risks subject to market risk capital requirements mainly includes: interest rate risk, credit spread risk, equity risk, foreign exchange (FX) risk and commodities risk for trading book instruments; and FX risk and commodities risk for banking book instruments. The FMC does not permit banks to use internal models for calculating MRWA and instead only permits the usage of simple standardized models. The following table sets forth our RWA and regulatory capital as of December 31, 2025 under Basel III as required by the Chilean regulator as of this reporting date. Risk-weighted assets December 31 2025 Ch$ million Market risk 7,143,966 Operational risk 5,019,913 Credit risk 29,551,588 Total RWA 41,715,467 Ratio December 31 2025 December 31 2025 (Ch$ million) (% of RWA) Common Equity Tier 1 (CET1) 4,601,923 11.0 % Additional Tier I 629,468 1.5 % Tier I 5,231,391 12.5 % Tier II 1,815,930 4.4 % Regulatory capital 7,047,321 16.9 % We believe our capital levels are adequate, but we cannot rule out having to raise additional capital in the future to maintain our capital adequacy ratios above the minimum required by the FMC. 54 Table of contents Lending Limits Under the General Banking Law, Chilean banks are subject to certain lending limits, including the following material limits: •A bank may not extend to any entity or individual (or any one group of related entities), except for another financial institution, directly or indirectly, unsecured credit in an amount that exceeds 10.0% of the bank’s regulatory capital, or in an amount that exceeds 30.0% of its regulatory capital if the excess over 10.0% is secured by certain assets with a value equal to or higher than such excess. In the case of financing infrastructure projects built by government concession, the 10.0% ceiling for unsecured credits is raised to 15.0% if secured by a pledge over the concession, or if granted by two or more banks or finance companies which have executed a credit agreement with the builder or holder of the concession in the case of export loans in foreign currency the ceiling is raised to 30%; •a bank may not extend loans to another financial institution subject to the General Banking Law in an aggregate amount exceeding 30.0% of its regulatory capital; •a bank may not grant loans to a single business group, as defined in Title XV of Law 18,045, that exceeds 30% of the Bank’s regulatory capital, provided that such limit excludes interbank loans; •if a bank originates a loan in excess of these limits, a fine equivalent to 10% of the excess will be applied to the bank; •a bank may not directly or indirectly grant a loan whose purpose is to allow an individual or entity to acquire shares of the lender bank; •a bank may not lend, directly or indirectly, to a director or any other person who has the power to act on behalf of the bank; and •a bank may not grant loans to related parties (including holders of more than 1.0% of its shares) on more favorable terms than those generally offered to non-related parties. Loans granted to related parties are subject to the limitations described in the first bullet point above. In addition, the aggregate amount of loans to related parties may not exceed a bank’s regulatory capital. In addition, the General Banking Law limits the aggregate amount of loans that a bank may grant to its employees to 1.5% of its regulatory capital and provides that no individual employee may receive loans in excess of 10.0% of this 1.5% limit. Notwithstanding these limitations, a bank may grant each of its employees a single residential mortgage loan for personal use during such an employee’s term of employment. Allowance for Loan Losses under Chilean Bank GAAP Chilean banks are required to provide to the FMC detailed information regarding their loan portfolio on a monthly basis. The FMC examines and evaluates each financial institution’s credit management process, including its compliance with the loan classification guidelines. Banks are classified into four categories: 1, 2, 3 and 4. Each bank’s category depends on the models and methods used by the bank to classify its loan portfolio, as determined by the FMC. Category 1 banks are those banks whose methods and models are satisfactory to the FMC. Category 1 banks will be entitled to continue using the same methods and models they currently have in place. A bank classified as a category 2 bank will have to maintain the minimum levels of reserves established by the FMC while its Board of Directors will be made aware of the problems detected by the FMC and required to take steps to correct them. Banks classified as categories 3 and 4 will have to maintain the minimum levels of reserves established by the FMC until they are authorized by the FMC to do otherwise. Differences between IFRS and Chilean Bank GAAP Chilean Bank GAAP, as prescribed by the Compendium of Accounting Standards (the “Compendium”), differs in certain respects from IFRS. The main differences that should be considered by an investor are the following: 55 Table of contents Suspension of Income Recognition on Accrual Basis 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 related payments are received. This difference does not materially impact our Audited 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 Audited 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 the Audited 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 main difference between Chilean Bank GAAP and IFRS 9 regarding loan loss allowances is that loan loss allowances under Chilean GAAP are calculated using expected loss models based on specific guidelines set by the FMC. The models adopted with IFRS 9 use 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 adopted the IFRS 9 Impairment chapter and therefore the Bank has adjusted the Audited Consolidated Financial Statements to fully comply with IFRS standards. Provisions for Country Risk and for Contingent Loan Risk Under Chilean Bank 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. Our provisions for country risk as of December 31, 2025 were not material. Under Chilean Bank GAAP, the Bank has established allowances related to the undrawn available credit lines and contingent loans in accordance with the FMC. Under IFRS 9, provisions for contingent loans are calculated based on expected credit loss. The Bank has adjusted the Audited Consolidated Financial Statements accordingly. These differences do not have a material impact on our financial statements. 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 56 Table of contents 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 our consolidated financial statements for the differences between Chilean Bank GAAP and IFRS, we adjust deferred taxes accordingly. Provision for Mandatory Dividends This provision is made in accordance with the Bank’s internal policy and Article 79 of the Chilean Companies Law, pursuant to which at least 30% of net income for the period is distributed, except 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 Bank 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 Bank 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. Capital Markets Under the General Banking Law, banks in Chile may purchase, sell, place, underwrite and act as paying agents with respect to certain debt securities. Likewise, banks in Chile may place and underwrite certain equity securities. Bank subsidiaries may also engage in debt placement and dealing, equity issuance advice and securities brokerage, as well as in financial leasing, mutual fund and investment fund administration, investment advisory services and merger and acquisition services. These subsidiaries are regulated by the FMC. Legal Provisions Regarding Banking Institutions with Economic Difficulties Article 112 of the General Banking Law provides that if specified adverse economic circumstances exist at any bank, its Board of Directors must approve a financing plan to correct the situation and present it to the FMC. In its proposal, the bank must state the scheduled time within which the plan will be completed, which may not exceed 6 months. If one of the measures contained in the financing plan is to increase the capital of the bank by the amount necessary to return the bank to financial stability, the Board of Directors must call a special shareholders’ meeting to the capital increase. If the shareholders reject the capital increase, the FMC may apply one or more of the restrictions stated in Article 116 of the General Banking Law for a period not exceeding 6 months, which may be renewed once for the same period. These restrictions include limiting the bank’s ability to grant loans to any person or legal entity linked (directly or through third parties) to the property or management of the bank, limiting loan renewals for more than 180 days, limiting security documents governing existing loans, among others. If the approval of shareholders is required for a different measure included in the plan, the Board of Directors must call the shareholders’ meeting within 15 days. The General Banking Law provides that the bank may receive a three-year term loan from one or more banking institutions. The terms and conditions of such a loan must be approved by the directors of both banks, as well as by the FMC, but need not be submitted to any institution’s shareholders for their approval. In any event, a creditor bank cannot grant interbank loans to an insolvent bank in an amount exceeding 25.0% of the creditor bank’s regulatory capital. If the bank is unable to pay the loan to its creditors, article 115 of the General Banking Law provides that a bank’s unpaid debt may be: (i) capitalized in a merger between the bank and creditor bank, where the creditor bank may establish the terms and conditions of the merger provided such terms and conditions are approved by the FMC; (ii) used to complete a capital increase agreed by the bank, provided that the shares are issued by a third party; and 57 Table of contents (iii) to subscribe and pay a capital increase. The shares acquired by the creditor bank must be sold within a period of 180 days, which can be extended by the FMC for a further 180 days. Dissolution and Liquidation of Banks The FMC may establish that a bank should be liquidated for the benefit of its depositors or other creditors when such bank does not have the necessary solvency to continue its operations. In such case, the FMC must revoke a bank’s authorization to exist and order its mandatory liquidation, subject to agreement by the Central Bank. The FMC must also revoke a bank’s authorization if the reorganization plan of such bank has been rejected twice. The resolution by the FMC must state the reason for ordering the liquidation and must name a liquidator, unless the FMC assumes this responsibility. When a liquidation is declared, all checking accounts and other demand deposits received in the ordinary course of business are required to be paid by using existing funds of the bank, its deposits with the Central Bank or its investments in instruments that represent its reserves. If these funds are insufficient to pay these obligations, the liquidator may seize the rest of the bank’s assets, as needed. If necessary and in specified circumstances, the Central Bank will lend the bank the funds necessary to pay these obligations. Any such loans are preferential to any claims of other creditors of the liquidated bank. On January 12, 2019, Law No. 21,130 was published in the Official Gazette of Chile. The law modernizes banking legislation including the General Banking Law by, among other things, transferring the supervisory powers of the Superintendency of Banks and Financial Institutions (SBIF) to the FMC, updating the capital and risk management requirements applicable to banking companies in accordance with the Basel III standards, and introducing measures for the early regularization and intervention of banking companies that are at risk of insolvency. With respect to measures for early regularization, Law No. 21,130 establishes an obligation on banks to inform the FMC if any of the regulatory non-compliance situations listed in Article 112 of the General Banking Law arise or if it has detected any event indicative of financial instability or deficient administration. Within five days of notifying the FMC, the bank must present a regularization plan approved by its board of directors containing concrete measures that shall remedy the relevant situation and ensure the bank’s normal performance. The bank must comply with the regularization plan within 6 months of the resolution approving it. During the implementation of the plan, the bank must also submit periodic reports on its progress to the FMC, and the FMC may require the implementation of additional measures and/or prohibitions it deems necessary for the plan’s success. Article 161 of the General Banking Law provides that directors, managers, administrators and attorneys-in-fact who, without written authorization from the FMC, agree to, perform or cause the execution of any of the acts prohibited under Article 116 of the General Banking Law shall be imprisoned for a term within the medium to maximum range. If a bank fails to submit the regularization plan, the plan is rejected by the FMC, the bank fails to comply with any of the measures set out in the plan, the bank repeatedly breaches the plan’s terms or is subject to fines, or if any serious event occurs that raises concerns for the bank’s financial stability, the FMC may appoint a delegated inspector, who shall have powers to, among other things, suspend any agreement of the board of directors or act of the attorneys-in-fact of the institution, and/or a provisional administrator, who shall have all the ordinary faculties that the law and the by-laws provide for the board of directors, or whoever acts in its place, and for the general manager. Other amendments incorporated by Law No. 21,130 include the elimination of creditors’ agreements as a mechanism for regularizing a bank’s financial situation, the incorporation of modifications to financial system capitalization and preventive capitalization, and the incorporation of further requirements for bank directors. Obligations Denominated in Foreign Currencies Santander-Chile must also comply with various regulatory and internal limits regarding exposure to movements in foreign exchange rates (See “Item 11. Quantitative and Qualitative Disclosures About Market Risk”). Foreign Loans and Investments in Foreign Securities Under current Chilean banking regulations, banks in Chile may grant loans to foreign individuals and entities and invest in certain securities of foreign issuers. Chapter 3 Section B.5-3 and Section B.5-4 of the Central Bank’s Financial Norms regulate a bank’s investment in foreign loans and investment in foreign securities. Banks in Chile may invest in debt securities traded in formal secondary markets. Such debt securities must be (1) securities issued or guaranteed by foreign sovereign states or their central banks or other foreign or international financial entities, and (2) bonds issued by 58 Table of contents foreign companies. If the sum of investment in foreign securities and loans granted outside of Chile surpasses 70.0% of regulatory capital, the amount that exceeds 70.0% is subject to a mandatory loan loss reserve of 100%. Table 1 Rating Agency Short Term Long Term Moody’s P2 Baa3 Standard and Poor’s A3 BBB- Fitch F2 BBB- Dominion Bond Rating (DBRS) R-2 BBB (low) In the event that the sum of: (a) loans granted abroad that are not to subsidiaries of Chilean companies, and that have a rating of BB- or less and do not trade on a foreign stock exchange, and (b) the investments in foreign securities which have a rating that is below that indicated in Table 1 above, but is equal to or exceeds the ratings mentioned in the Table 2 below and exceeds 20.0% (and 30.0% for banks with a BIS ratio equal or exceeding 10% of the regulatory capital of such bank), the excess is subject to a mandatory loan loss reserve of 100%. Table 2 Rating Agency Short Term Long Term Moody’s P2 Ba3 Standard and Poor’s A-2 BB- Fitch F2 BB- DBRS R-2 BB (low) In addition, banks may invest in foreign securities whose ratings are equal to or exceed those mentioned in Table 3 below for an additional amount equal to 70% of their regulatory capital. This limit constitutes an additional margin and is not subject to the 100% mandatory reserve. Additionally, a Chilean bank may invest in foreign securities whose rating is equal to or exceeds those mentioned in Table 3 below in: (i) demand deposits with foreign banks, including overnight deposits in a single entity; and (ii) securities issued or guaranteed by sovereign states or their central banks or securities issued or guaranteed by foreign entities within the Chilean State, though investment will be subject to the limits by issuer up to 30.0% and 50.0%, respectively, of the regulatory capital of the Chilean bank that makes the investment. If these foreign securities do not have a rating, the individual limit will be 10.0% of regulatory capital. Table 3 Rating Agency Short Term Long Term Moody’s P1 Aa3 Standard and Poor’s A1+ AA- Fitch F1+ AA- DBRS R-1 (high) AA(low) Moreover, the sum of all demand deposits with foreign banks, including overnight deposits to related parties, as defined by the Central Bank and the FMC cannot surpass 25.0% of a bank’s regulatory capital. This limit excludes foreign branches of Chilean banks or their subsidiaries but must include amounts deposited by these entities in related parties abroad. Banks may grant commercial loans and foreign trade loans and can buy loans granted by banks abroad. Chilean banks may only invest in equity securities of foreign banks and certain other foreign companies which may be affiliates of the bank or which would be complementary to the bank’s business if such companies were incorporated in Chile. 59 Table of contents United States Supervision and Regulation Financial Regulatory Reform Santander-Chile is a subsidiary of Santander Spain, a foreign banking organization (“FBO”) with operations in the United States. As a subsidiary of Santander Spain, Santander-Chile is subject to certain U.S. financial regulatory laws and rules. In addition to regulations, the U.S. financial regulatory agencies may issue policy statements, interpretive letters and similar written guidance. Financial regulatory statutes and rules are continually under review by the U.S. Congress and U.S. financial regulatory agencies. Changes in key personnel at the U.S. financial regulatory agencies may result in differing interpretations of existing rules and guidelines and potentially more stringent enforcement and more severe penalties than previously. The full spectrum of risks that result from pending or future U.S. financial services legislation or regulations cannot be fully known; however, such risks could be material and we could be materially and adversely affected by them. Volcker Rule Owing to its status as a subsidiary of an FBO, Santander-Chile is subject to Section 13 of the U.S. Bank Holding Company Act and its implementing rules (collectively, the “Volcker Rule”). The Volcker Rule prohibits “banking entities” from engaging in certain forms of proprietary trading or from sponsoring or investing in “covered funds,” in each case subject to certain exceptions. The Volcker Rule also limits the ability of banking entities and their affiliates to enter into certain transactions with covered funds with which they or their affiliates have certain relationships. The Group has adopted processes to establish, maintain, enforce, review and test the compliance program designed to achieve and maintain compliance with the Volcker Rule. The Volcker Rule contains exclusions and certain exemptions for, among others, market-making, hedging, underwriting, trading in U.S. government and agency obligations and certain foreign government obligations, and trading solely outside the United States, and also permits certain ownership interests in certain types of funds to be retained. Santander Spain’s non-U.S. banking organization subsidiaries, including Santander-Chile, are largely able to continue their activities outside the United States in reliance on the “solely outside the U.S.” exemptions from the Volcker Rule. Those exemptions generally exempt proprietary trading, and sponsoring or investing in covered funds if, among other restrictions, the essential actions take place outside the United States. Santander Spain will continue to monitor Volcker Rule-related developments and assess their impact on its operations, including those of Santander-Chile, as necessary. Other U.S. Financial Regulations Santander Spain is subject to other U.S. financial regulatory regimes that do not directly apply to Santander-Chile based on the current scope of its operations. For example, Santander Spain, as a Category IV FBO, and Santander Holdings USA, Santander Spain’s U.S. intermediate holding company (“IHC”), as a Category IV IHC, are subject to enhanced prudential standards imposed by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) on large banking organizations that exceed certain asset thresholds. Enhanced prudential standards include risk-based and leverage capital requirements, liquidity requirements, risk management and governance requirements, capital planning and stress testing requirements, resolution planning requirements, and risk management requirements. Category IV institutions are subject to the least exacting level of enhanced prudential standards. In addition, Santander Spain is registered as a non-US swap dealer with the CFTC and is registered as a non-US security-based swap dealer with the SEC. As such, Santander Spain is subject to certain clearing, exchange trading, uncleared swap margin, business conduct, reporting and other requirements. Foreign Corrupt Practices Act Regulations Santander-Chile, as a foreign private issuer whose securities are registered under the U.S. Securities Exchange Act of 1934, is subject to the U.S. Foreign Corrupt Practices Act (the “FCPA”). The FCPA generally prohibits such issuers and 60 Table of contents their directors, officers, employees and agents from using any means or instrumentality of U.S. interstate commerce in furtherance of any offer or payment of money to any foreign official or political party for the purpose of influencing a decision of such person in order to obtain or retain business. It also requires that the issuer maintain books and records and a system of internal accounting controls sufficient to provide reasonable assurance that accountability of assets is maintained, and accurate financial statements can be prepared. Penalties, fines and imprisonment of Santander-Chile’s officers and/or directors can be imposed for violations of the FCPA. Disclosure pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012, which added Section 13(r) to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), an issuer is required to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with individuals or entities designated pursuant to certain Executive Orders. Disclosure is generally required even where the activities, transactions or dealings were conducted in compliance with applicable law. The following activities are disclosed in response to Section 13(r) with respect to the Group and its affiliates. During the period covered by this report: •Frozen accounts and transactions: A limited number of accounts for customers subsequently designated over time by the US under the Specially Designated Global Terrorist (SDGT) sanctions program, were or are maintained with certain non-US affiliates of Santander. All accounts have been frozen or cancelled to comply with applicable legal requirements. •Legacy contractual obligations related to guarantees: The Group also has certain legacy performance guarantees for the benefit of an Iranian bank that is currently designated by the US under the Specially Designated Global Terrorist (SDGT) sanctions program (stand-by letters of credit to guarantee the obligations – either under tender documents or under contracting agreements – of contractors who participated in public bids in Iran) that were in place prior to 27 April 2007. The Group is not contractually permitted to cancel these arrangements without paying the guaranteed amount. As such, the Group intends to continue to provide the guarantees in accordance with company policy and applicable laws. In the aggregate, all the transactions described above resulted in gross revenues and net profits in the year ended December 31, 2025, which were negligible relative to the overall revenues and profits of Santander. The Group has undertaken significant steps to withdraw from the Iranian market such as closing its representative office in Iran and ceasing all banking activities therein, including correspondent relationships, deposit taking from Iranian entities and issuing export letters of credit, except for the legacy transactions described above.

Accounting Standards Applied in 2025 Santander-Chile is a Chilean bank and maintains its financial books and records in Chilean pesos and prepares its consolidated financial statements in accordance with IFRS as issued by the IASB in order to comply with requirements of the SEC. As required by the General Banking Law, which subjects Chilean banks to the regulatory supervision of the FMC, and which mandates that Chilean banks abide by the accounting standards stipulated by the FMC, our locally filed consolidated financial statements have been prepared in accordance with Chilean Bank GAAP as issued by the FMC. The accounting principles issued by the FMC are substantially similar to IFRS but there are some exceptions, as described in “Item 4. Information on the Company—Differences between IFRS and Chilean Bank GAAP.” Therefore, our locally filed consolidated financial statements have been adjusted according to IFRS as issued by the IASB. Critical Accounting Policies Our consolidated financial statements include various estimates and assumptions, including but not limited to the adequacy of the allowance for loan losses, estimates of the fair value of certain financial instruments and the selection of useful lives of certain assets. We evaluate these estimates and assumptions on an ongoing basis. Management bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances. Actual results in future periods could differ from those estimates and assumptions, and if these differences were significant enough, our reported results of operations would be affected materially. We believe that the following are the most critical judgment areas or involve a higher degree of complexity in the application of the accounting policies that currently affect our financial condition and results of operations. 63 Table of contents Allowance for Loan Losses under IFRS 9 The impairment model applies to all financial assets measured at amortized cost and fair value through other comprehensive income (“FVOCI”), including loan commitments and contingent loans. The Bank accounted the expected credit losses (“ECL”) related to financial assets measured at amortized cost and FVOCI as a loss allowance in the statement of financial position and the carrying amount of these assets is stated net of the loss allowance. The ECL related to contingent loans are accounted as a provision in the statement of financial position. For financial assets that are measured at fair value through other comprehensive income, the loss allowance is recognized in other comprehensive income and does not reduce the carrying amount of the financial asset in the statement of financial position. The new model uses a dual measurement approach, under which the loss allowance is measured as either: (a) 12-month expected credit losses or (b) lifetime expected credit losses. Based on changes in credit quality since initial recognition, IFRS 9 outlines a “three-stage” impairment model as illustrated by the following chart: Change in credit quality since initial recognition Stage 1 Stage 2 Stage 3 Initial recognition Significant increase in credit risk since initial recognition Credit impaired assets 12-month expected credit losses Lifetime expected credit losses Lifetime expected credit losses The Bank, at the end of each reporting period, evaluates whether a financial instrument’s credit risk has increased since initial recognition, and consequently classifies the financial instrument in the relevant stage: •Stage 1: At initial recognition of a loan or when there has been an improved credit risk following a significant increase or impairment of assets, the Bank recognizes an allowance based on 12 months ECL. •Stage 2: When a loan has shown a significant increase in credit risk since origination, the Bank records an allowance for the lifetime ECL. Stage 2 loans also include loans where the credit risk has improved following a Stage 3 classification. •Stage 3: Loans considered credit impaired. The Bank records an allowance for the lifetime ECL, setting the probability of default at 100%. The Bank considers reasonable and verifiable information available without undue cost or effort to it that may affect the credit risk on a financial instrument, including forward-looking information to determine whether there is or has been a significant increase in credit risk since initial recognition of a loan. Forward-looking information includes past events that affect future performance, current conditions and forecasts of future economic conditions. Expected credit loss measurement The ECL is the probability-weighted estimate of credit losses, i.e., the present value of all cash shortfalls. A cash shortfall is the difference between the cash flows that are due to an entity in accordance with the contract and the cash flows that the entity expects to receive. The three main components in measuring ECL are: •PD: The probability of default is an estimate of the likelihood of default over a given time period. A default may only happen at a certain time over the assessed period, if the facility has not been previously de-recognized and is still in the portfolio. •LGD: The loss given default is an estimate of the loss arising after a specific default. It is based on the difference between the contractual cash flows due and those that the lender would expect to receive, including from the realization of any collateral. •EAD: The exposure at default is an estimate of the exposure at a future default date, taking into account expected changes in the exposure after the reporting date, including repayments of principal and interest, whether scheduled by contract or otherwise, expected drawdown on committed facilities and accrued interest from missed payments. 64 Table of contents For measuring 12-month and lifetime expected credit losses, cash shortfalls are identified as follows: •12-month expected credit losses: the portion of lifetime expected credit losses that represents the expected credit losses that result from default events on the financial instruments that are possible within the 12 months after the reporting date. •Lifetime expected credit losses: the expected credit losses that result from all possible default events over the expected life of the financial instrument. Forward-looking information The ECL model includes a broad range of forward-looking information as economic inputs, such as: •GDP growth; •Unemployment rates; •Central Bank interest rates; and •Real estate prices. Interbank loans According to the balance presentation required under IFRS 9, the Bank has grouped interbank loans with loans and accounts receivable since both are measured at amortized cost and are evaluated together for impairment purposes. Contingent loans The Bank enters into various irrevocable loan commitments and contingent liabilities. Even though these obligations may not be recognized on the statement of financial position, they contain credit risk and, therefore, form part of the overall risk of the Bank. When the Bank estimates the ECL for contingent loan commitments and letters of credit, it estimates the expected portion of the loan commitment that will be drawn down over its expected life. Loans and account receivable measured at fair value through other comprehensive income When the Bank enters into arrangements with its major customers for project finance and syndicated loans, the amount requested sometimes exceeds the Bank’s limit for single client exposure under credit risk policy, so these operations are approved under the condition that a portion of the loans be sold in the near term. The Bank also has loans that it expects to sell if market conditions are favorable to the Bank. These loans are measured at fair value through other comprehensive income and are subject to impairment requirements. Valuation of Financial Instruments Fair value is the price that would be received to sell an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. IFRS 13 provides a hierarchy that separates the inputs and/or valuation technique assumptions used to measure the fair value of financial instruments. The hierarchy reflects the significance of the inputs used in making the measurement. The hierarchy gives the highest priority to (unadjusted) quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The Bank uses valuation techniques appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. For financial instruments with no available market prices, fair values are estimated using recent transactions in analogous instruments, and in the absence thereof, the present values or other valuation techniques based on mathematical valuation models sufficiently accepted by the international financial community. In the use of these models, consideration is given to the specific particularities of the asset or liability to be valued, and especially to the different kinds of risks associated with the asset or liability. 65 Table of contents These techniques are significantly influenced by the assumptions used, including the discount rate, the estimates of future cash flows and prepayment expectations. See “Note 36—Fair Value of Financial Assets and Liabilities” in our Audited Consolidated Financial Statements. Derivative Activities Derivatives are measured at fair value on the statement of financial position and the net unrealized gain (loss) on derivatives is classified as a separate line item within the income statement. Under IFRS, banks must mark-to-market derivatives. Within the fair value of derivatives are included Credit Valuation Adjustment (“CVA”) and Debit Valuation Adjustment (“DVA”), all with the objective that the fair value of each instrument includes the credit risk of its counterparty and the Bank’s own risk. The CVA is a valuation adjustment to OTC derivatives as a result of the risk associated with the credit exposure assumed by each counterparty in each future period. The DVA is a valuation adjustment similar to the CVA but, in this case, it arises as a result of the Bank’s own risk assumed by its counterparties. The following inputs are used to calculate the CVA and DVA: •Expected exposure: Including for each transaction the mark-to-market (MtM) value plus an add-on for the potential future exposure for each period. Mitigating factors such as collateral and netting agreements are taken into account, as well as a temporary impairment factor for derivatives with interim payments. •LGD: percentage of final loss assumed in a counterparty credit event/default. •Probability of default: for cases where there is no market information, proxies based on comparable companies in the same industry and with the same external rating as the counterparty, are used. •Discount factor curve. Deferred Tax Assets and Liabilities 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. The measurement of deferred tax assets and liabilities is based on the tax rate, in accordance with the applicable tax laws, using the tax rate that applies to the period when the deferred asset and liability will be settled. The future effects of changes in tax legislation or tax rates are recorded in deferred taxes beginning on the date on which the law is enacted or substantially enacted. See “Note 13—Current and Deferred Taxes” of our Audited Consolidated Financial Statements. Provisions – Contingent Liabilities Provisions related to contingencies associated to pending signature of contracts, potential clients and other administrative claims, operational risk arise from financial transactions, potential property tax associated to leasing contracts are quantified using the best available information of uncertain future events that are not wholly within control of the Bank. These are reviewed and adjusted at each reporting date. See “Note 19—Provisions and Contingent Provisions” of our Audited Consolidated Financial Statements. A.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. In 2025, Chile’s economy is expected to grow 2.4% as compared to 2.6% in 2024 and 0.5% in 2023. The Central Bank's reference rate, which is used to set monetary policy, finished 2025 at 4.50% compared to 5.00% in 2024 and 8.25% in 2023. The unemployment rate for 2025 remained elevated at 8.5%. The observed exchange rate appreciated 9.4% in 2025, depreciated 13.7% in 2024 and depreciated 2.9% in 2023. The appreciation of the Chilean peso in 2025 was mainly due to a weaker U.S. dollar globally. Currently, the Central Bank expects GDP to increase in a range between 1.5%-2.5% in 2025. Total loans as of December 31, 2025, in the Chilean financial system, excluding loans held abroad by Chilean banks, grew 2.6% year-over-year. Total customer deposits (defined as time deposits plus checking accounts), excluding amounts 66 Table of contents held by Chilean banks abroad, increased 5.8% year-over-year as of December 31, 2025. The non-performing loans (defined as loans with an installment that is at least 90 days past-due) to total loans ratio increased from 2.1% as of December 31, 2024 to 2.5% as of December 31, 2025. This was mainly driven by asset quality weakness caused by the sluggish economic growth and high unemployment rates. 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$39,727.96 as of December 31, 2025, Ch$38,416.69 as of December 31, 2024, Ch$36,789.36, and as of December 31, 2023. 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. Inflation measured as the annual variation of the UF was 3.4% in 2025, 4.4% in 2024, and 4.8% in 2023. 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 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: •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. •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$236,523 in 2025, a loss of Ch$535,558 million in 2024, and a loss of Ch$1,147,193 million in 2023. 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$7,403,454 million in 2025, Ch$7,518,560 million in 2024 and, Ch$6,875,280 million in 2023. Therefore, our sensitivity to a 100-basis point shift in UF inflation considering our average gap in 2025 would be approximately Ch$74 billion. 67 Table of contents The financial impact of the gap between our interest earning assets and liabilities denominated in UFs including hedges was as follows: As of December 31, % Change 2025 2024 2023 2025/2024 2024/2023 (in millions of Ch$) Impact of inflation on net interest income Results from UF GAP(1) 253,849 323,751 321,698 (21.6 %) 0.6 % Annual UF inflation 3.4 % 4.4 % 4.8 % (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. •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 5. Operating and Financial Review and Prospects—A. 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 ratio of the average of such demand deposits and average shareholder’s equity to average interest-earning assets was 31.3%, 30.7%, and 29.0% for the years ended December 31, 2025, 2024 and 2023, respectively. 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 9.4% in 2025, depreciated 13.7% in 2024 and depreciated 2.9% in 2023. 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 68 Table of contents 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 11. Quantitative and Qualitative Disclosures About Market Risk—E. Market Risks—Foreign exchange fluctuations” for more detail on the Bank’s exposure to foreign currency. Consolidated Ratios We use certain consolidated ratios to measure profitability and efficiency when planning, monitoring and evaluating our performance.

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. Results of Operations for the Years Ended December 31, 2025 and 2024 In this section, we discuss the results of our operations for the year ended December 31, 2025 compared to the year ended December 31, 2024. For a discussion of the results of our operations for the year ended December 31, 2024 compared to the year ended December 31, 2023, please refer to “Item 5. – A. Operating Results – Results of Operations for the Year Ended December 31, 2024 Compared to the Year Ended December 31, 2023” in our Annual Report on Form 20-F for the year ended December 31, 2024. The following discussion is based on and should be read together with the Audited Consolidated Financial Statements. The Audited Consolidated Financial Statements have been prepared in accordance with IFRS as issued by the IASB. The following table sets forth the principal components of our net income for the years ended December 31, 2025 and 2024. 70 Table of contents Consolidated Income Statement Data IFRS 2025 2025 2024 % Change 2025/2024 (U.S.$ thousands)(1) (Ch$ million) Interest income and inflation 4,214,113 3,795,609 4,094,817 (7.3 %) Interest expense and inflation (2,008,378) (1,808,926) (2,308,031) (21.6 %) Net interest income 2,205,734 1,986,683 1,786,786 11.2 % Fees and commission income 1,155,385 1,040,644 960,168 8.4 % Fees and commission expense (493,858) (444,813) (413,102) 7.7 % Total net fees and commission income 661,527 595,831 547,066 8.9 % Net income/(expense) from financial assets and liabilities for trading (48,358) (43,556) 85,013 (151.2 %) Net income from derecognizing financial assets and liabilities at amortized cost and financial assets at fair value through other comprehensive income 3,262 2,938 (37,068) (107.9 %) Net income from exchange, adjustment and hedge accounting of foreign exchange 329,081 296,400 202,574 46.3 % Net income from financial operations 283,985 255,782 250,519 2.1 % Income from investments in associates and other companies 10,313 9,289 10,436 (11.0) % Net income from non-current assets and groups available for sale not admissible as discontinued operations 8,042 7,243 4,049 78.9 % Other operating income 7,790 7,016 8,048 (12.8) % Total operating income 3,177,391 2,861,844 2,606,904 9.8 % Personnel salaries and expenses (458,429) (412,902) (398,819) 3.5 % Administrative expenses (430,342) (387,605) (366,431) 5.8 % Depreciation and amortization (150,062) (135,159) (141,435) (4.4 %) Impairment of property, plant and equipment (4,160) (3,747) (1,295) 189.3 % Other operating expenses (112,917) (101,703) (114,739) (11.4) % Total operating expenses (1,155,909) (1,041,116) (1,022,719) 1.8 % Net operating income before credit losses 2,021,481 1,820,728 1,584,185 14.9 % Provisions for loan losses for interbank loans and account receivable from customers (833,291) (750,537) (660,814) 13.6 % Provisions for loan losses for contingent loans and others (14,951) (13,466) 2,902 (564.0 %) Recovery of loans previously charged-off 213,880 192,640 153,944 25.1 % Provision for loan losses for other financial assets at amortized cost and financial assets at fair value through OCI (4,387) (3,950) (622) 535.0 % Provision for loan losses (638,747) (575,313) (504,590) 14.0 % Net operating income before income tax 1,382,734 1,245,415 1,079,595 15.4 % Income tax expense (230,226) (207,362) (219,745) (5.6 %) Result of discontinued operations — — — — % Net income for the year 1,152,509 1,038,053 859,850 20.7 % Net income for the year attributable to: Shareholders of the Bank 1,134,297 1,021,650 852,964 19.8 % Non-controlling interests 18,212 16,403 6,886 138.2 % (1)Amounts stated in U.S. dollars at and for the year ended December 31, 2025 have been translated from Chilean pesos at the exchange rate of Ch$900.69= U.S.$1.00 as of December 31, 2025. 71 Table of contents Results of Operations for the Years Ended December 31, 2025 and 2024 Net income for the year attributable to shareholders of the Bank increased 19.8% in 2025 compared to 2024 and totaled Ch$1,021,650 million. Our return on annualized average equity (adjusted to exclude the AT1 perpetual bond) was 20.8% in 2025 compared to 19.5% in 2024. Our net interest income increased 11.2% in 2025 compared to 2024. Net interest income from our reporting segments totaled Ch$2,248,468 million in 2025 and increased 3.8% compared to 2024. This rise was mainly due to a higher-yield asset mix and lower funding costs that benefited from the lower interest rate environment in Chile in 2025. Our interest-bearing liabilities have a shorter maturity than our interest-earning assets and, therefore, incorporate rate cuts more quickly. The increase in net interest income was also due to a decrease in the loss in “other” net interest income, which totaled a loss of Ch$261,785 million in 2025 compared to a loss of Ch$379,913 million in 2024. Overall, our net interest margin increased from 3.36% in 2024 to 3.79% in 2025. Net fees and commission income increased 8.9% to Ch$595,831 million in 2025 compared to the same period in 2024. Fee growth in 2025 was driven by client growth and cross-selling indicators driven by greater availability and usage of our digital platforms. This resulted in a 12.8% increase in fees from debit and credit cards, a 38.8% increase in fees generated by our acquiring subsidiary Getnet, a 21.7% rise in commission income from brokerage of mutual funds, a 10.5% increase in account management fees, among other items. Total net income from financial operations reached Ch$255,782 million and increased 2.1% in 2025 compared to 2024. Income from client treasury services totaled Ch$249,648 million, a decrease of 8.7% compared to 2024. In 2025, demand for interest rate and foreign exchange treasury products on behalf of corporate clients declined as volatility decreased in the year in both the interest rate and foreign exchange markets. The results from non-client treasury income totaled Ch$6,134 million in 2025 compared to a loss of Ch$22,845 million in 2024. Non-client treasury 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. In 2025, long-term interest rates fell producing higher realized gains from the sale of fixed income instruments and better results from the repurchase of bonds issued by the Bank. Operating expenses in the year ended December 31, 2025 increased 1.8% compared to the corresponding period in 2024. The efficiency ratio was 36.4% in 2025 and 39.2% in 2024. Personnel salaries and expenses in the year ended December 31, 2025 increased 3.5% compared to the corresponding period in 2024, mainly due to the increase in inflation, as most of the wages paid by the bank pursuant to collective bargaining agreements are indexed to the Chilean CPI, as well as higher variable pay, which was, partially offset by the decrease in headcount. Administrative expenses increased 5.8% in the year ended December 31, 2025 compared to the corresponding period in 2024 primarily due to investments in core systems, cloud computing and technology-related initiatives supporting the modernization of our commercial platforms. Depreciation and amortization expense decreased 4.4% in 2025 compared to 2024, mainly due to lower depreciation of right of use assets and intangible assets, in line with the reduction of the number of branches. Other operating expenses fell 11.4% in 2025 compared to 2024. This decline mainly corresponds to a lower restructuring charges which decreased from Ch$43,156 million in 2024 to Ch$34,164 million in 2025. Operating income increased 9.8% in 2025 compared to an increase of only 1.8% in operating expenses, which drove the 14.9% increase in net operating income before credit losses. For the year ended December 31, 2025, provisions for loan losses totaled Ch$638,747 million and increased 14.0% compared to 2024. This increase was mainly due to a Ch$76,823 million increase in the provision expense for mortgage and consumer loans and a Ch$20,495 million increase in loan loss provisions in the Middle Market segment. This was mainly due to the sluggish growth of the economy and persistently high unemployment rates that led to higher loan losses and write-offs. This was partially offset by the 25.1% rise in recovery of loans previously written-off. Total income tax expense by the Bank in 2025 was Ch$207,362 million and decreased 5.6% compared to 2024. The decrease in income tax expenses in 2025 compared to 2024 mainly reflects the lower growth of the CPI in 2025 compared to 2024 due to the fact that our capital in our Chilean tax books is recast each year based on the variation in the CPI, which causes a tax loss, as well as timing differences between accounting and tax treatment of certain bonds. See “Note 13—Current and Deferred Taxes” of the Audited Consolidated Financial Statements for more detail on income tax expense. 72 Table of contents Therefore while, the statutory corporate tax rate in Chile in 2024 and 2025 was 27%, the Bank recognized an effective tax rate of 16.7% in 2025 compared to 20.4% in 2024. Net Interest Income Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$, except percentages) Retail banking 1,642,104 1,559,556 5.3 % Wealth Management & Insurance 59,789 57,773 3.5 % Middle-market 334,660 314,230 6.5 % Corporate Investment banking 211,915 235,140 (9.9 %) Total reporting segments 2,248,468 2,166,699 3.8 % Other(1) (261,785) (379,913) 31.1 % Net interest income 1,986,683 1,786,786 11.2 % Average interest-earning assets 52,430,092 53,180,232 (1.4 %) Average non-interest-bearing demand deposits 10,837,345 11,317,733 (4.2 %) Net interest margin(2) 3.79 % 3.36 % Average shareholders’ equity and average non-interest-bearing demand deposits to total average interest-earning assets 31.32 % 30.74 % (1)Consists mainly of net interest income from the Financial Management Division, including the result of the Bank’s inflation gap as well as the net impact of derivatives used to hedge our exposure to inflation or shifts on interest rates and the cost of funding our financial assets held for trading. Each segment obtains funding from its clients. Any surplus deposits are transferred to the Financial Management Division, which in turn makes such excess available to other areas that need funding. The Financial Management Division also sells the funds it obtains in the institutional funding market at a transfer price equal to the market price of the funds. This segment also includes intra-segment income and activities not assigned to a given segment or product line. (2)Net interest margin is net interest income divided by average interest-earning assets. For the year ended December 31, 2025, our net interest income totaled Ch$1,986,683 million and increased 11.2% compared to 2024. Average interest earning assets decreased 1.4% in the same period. During 2025, the loan portfolio decreased 0.9% due to the decrease in commercial loans in CIB and a fall in residential mortgage loans. The average nominal interest rate earned on interest earning assets decreased from 7.7% in 2024 to 7.2% in 2025. This was mainly due to: (i) lower yields earned over interest earning assets denominated in UF due to the lower UF inflation rate in 2025 compared to 2024. The average interest rate earned over UF denominated interest earning assets reached 6.6% in 2025 compared to 7.4% in 2024; and (ii) lower yields earned over foreign currency interest earning assets, mainly due to lower rates in U.S. dollar-denominated interest earning assets. This fall in asset yields was partially offset by an increase in the yield earned over interest earning assets denominated in Chilean pesos. The average rate earned over interest earning assets denominated in Chilean pesos increased from 9.2% in 2024 to 9.5% in 2024. Despite a lower rate environment locally, the shift of the loan mix away from lending in CIB to consumer loans drove this rise in Ch$ denominated interest earning assets. Average nominal interest rate earned on interest earning assets 2025 2024 Ch$ 9.5 % 9.2 % UF 6.6 % 7.4 % Foreign currencies 3.7 % 4.7 % Total 7.2 % 7.7 % 73 Table of contents The fall in short-term interest rates and the lower UF inflation also lowered funding costs in 2025 compared to 2024. The average rate paid on our interest-bearing liabilities decreased from 6.3% in 2024 to 4.9% 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 5.0% in 2024 to 4.6% in 2025. The lower UF inflation rate in 2025 compared to 2024 also lowered funding costs of interest bearing liabilities denominated in this currency from 8.3% in 2024 to 5.9% in 2025. The funding mix also improved in 2025 as the ratio of average equity and non-interest bearing demand deposits to total average interest earning assets improved from 30.7% in 2024 to 31.3% in 2025, mainly driven by the rise in the Bank's average equity. Average nominal interest rate paid on interest bearing liabilities 2025 2024 Ch$ 5.9 % 8.7 % UF 5.9 % 8.3 % Foreign currencies 1.7 % 1.7 % Total 4.9 % 6.3 % In summary, the improved asset mix and the impact of lower rates on funding costs more than offset the impact of lower inflation and rates on interest earning assets, which drove our net interest margin to increase from 3.36% in 2024 to 3.79% in 2025. Net interest income from our reporting segments in 2025 totaled Ch$2,248,468 million and increased 3.8% compared to 2024. This rise was mainly due to asset growth in higher yielding loan products and lower funding costs. The quicker repricing of deposits in our business segments more than offset low loan growth and the declining yields earned on loans. •Net interest income from Retail banking increased 5.3% in 2025 compared to 2024. Total loans in the retail segment decreased 2.2% led by a 0.7% decrease in residential mortgage loans. This was partially offset by a 2.5% increase in consumer loans in the year. This fall in loan volumes was also offset by lower interest paid on time deposits as a result of the lower interest rate environment. •Net interest income from Wealth Management increased 3.5% in 2025 compared to 2024, mainly driven by the 13.0% growth in loan volumes in this segment and lower funding costs. This was partially offset by the lower yield earned over loans in this segment due to the lower rate environment. •Net interest income from the Middle-market segment increased 6.5% in 2025 mainly due to lower funding costs driven by a lower interest rate environment and the 2.2% increase in loans in this segment during the year. •Net interest income from the Corporate Investment Banking segment decreased 9.9% in 2025 compared to 2024 mainly due to the 7.1% reduction of this segment's loan portfolio in the year. In 2025, CIB continued to follow a generate-to-distribute model that implies originating and then selling loans in this segment, while focusing on the higher profitability products and services such as transactional services and treasury products in order to optimize capital usage levels. •The loss in Other net interest income improved 31.1% in 2025 compared to 2024. Other net interest income consists mainly of net interest income from the Bank’s Asset & Liability Management ("ALM") and is managed by the Banks Financial Management Division. This includes net interest income from the Bank’s debt instruments recorded at fair value through other comprehensive income, deposits in the Central Bank, and the financial cost of supporting our cash position and financial investments held for trading (the interest income from which is recognized as net income from financial operations and not interest income). The result of the Bank’s inflation gap is also included in this line as well as the net impact of derivatives used to hedge our inflation gap or views on interest rates. The result of corporate activities and ALM shows an improvement compared to the previous year, with the loss decreasing by 31.1% to Ch$261,785 million mainly due to an improvement in the cost of funding managed by this division in line with lower short-term rates, which improved the results from fair value hedges of interest rate risk on liabilities (micro hedges), mainly interest rate swaps. This shortened the duration of our liabilities and resulted in a lower rate paid over Central Bank and other borrowings. 74 Table of contents The following table shows our balances of loans and accounts receivable from customers and interbank loans by segment at the dates indicated. At December 31, % Change 2025 2024 2025/2024 (in millions of Ch) Retail banking 31,225,378 31,942,515 (2.2 %) Wealth Management & Insurance 924,692 818,155 13.0 % Middle-market 6,178,983 6,044,799 2.2 % Corporate Investment banking 2,139,201 2,301,491 (7.1 %) Other(1) 464,626 216,884 114.2 % Total loans 40,932,880 41,323,844 (0.9) % (1)Includes interbank loans. The following table shows interest income of financial assets by valuation as of December 31, 2025 and 2024. The 8.6% decrease is mainly due to the lower variation of the UF and the lower interest rate environment, which had a Ch$352,166 million negative impact on interest earning asset yields. At December 31, % Change 2025 2024 2025/2024 (in millions of Ch) Financial assets measured at amortized cost(1) 3,793,625 4,160,400 (8.8 %) Financial assets measured at FVOCI(2) 155,275 162,086 (4.2 %) Interest income not including income from hedge accounting 3,948,900 4,322,486 (8.6 %) (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. 75 Table of contents Fee and Commission Income Net fees and commission income increased 8.9% to Ch$595,831 million in the twelve-month period ended December 31, 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. This was partially offset by lower fees from financial advisory services following a record year in 2024 and lower prepayment fees in line with the lower interest environment that reduced demand for the prepayment of loans.

This rise was mainly due to greater usage of our cards. According to the latest information published by the CMF, Santander Chile's credit cardholders that actively use their cards increased by 5.0% to 1,405,294 in the twelve month period ended November 2025 compared to a 2.7% for banking industry. In the same period, monetary purchases with Santander Chile's credit cards increased 10.7% and market share in terms of total purchases reached 25.9%. 76 Table of contents Fees from Getnet, the Bank's subsidiary in the acquiring business, increased 38.8% in 2025 compared to 2024. This was driven by strong growth in the number of SME and large retail customers of Getnet and greater usage of cards for payments in Chile. The amount of POS terminals in operation increased 11.9% in 2025 compared to 2024. Fees from the brokerage of mutual funds increased 21.7% in 2025 compared to 2024 driven by a rise in sales of funds to our clients driven by positive returns in both the equity and fixed income funds. Fees from management of accounts increased 10.5% in 2025 compared to 2024 driven by continued strong account opening growth as a result of our client friendly digital platforms, such as Más Lucas and Santander Life, and positive evolution of client satisfaction and cross-selling indicators. Fees from collections and payments decreased 5.6% in 2025 compared to 2024 due to lower collection fees related to credit and insurance. Insurance brokerage fees decreased 9.1% due to lower commissions generated by insurance policies associated with mortgage loans driven by lower commercial activity in this product, in line with the decrease in volume in mortgage loans. Fees from guarantees and letters of credit increased 21.3% in 2025 compared to 2024 due to higher commissions from our corporate and middle-market clients, particularly related to Stand-by Letters driven by healthy growth trends in foreign trade and exports in 2025. Fees from financial advisory decreased 25.8% in 2025 due to a decrease in financial advisory services. The record year in financial advisory services in 2024 was not repeated in 2025, especially in the CIB segment. Fees from office banking, the Bank's online digital banking platform for companies, increased 3.2% in 2025 compared to 2024, mainly due to more and better functionalities that has driven higher usage of this banking platform by our corporate, middle-market and SME customers. Fees from the prepayment of loans decreased 8.8% in 2025 compared to 2024. As interest rates rates declined in the year the level of prepayment of loans also decreased. The 34.8% increase in the loss recorded in other fee income in 2025 compared to 2024 was mainly due higher fees paid for credit insurance. The following table sets forth, for the periods indicated our fee income broken down by segment for the periods indicated (See “Note 26—Fees and Commission” of our Audited Consolidated Financial Statements for more detail on fees by segment): Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Retail banking 503,186 454,194 10.8 % Wealth Management & Insurance 30,019 23,183 29.5 % Middle-market 52,921 43,954 20.4 % Corporate Investment banking 47,404 54,901 (13.7 %) Other (37,699) (29,166) 29.3 % Total fees and commission income, net 595,831 547,066 8.9 % Fees from Retail banking increased 10.8% in 2025 compared to 2024 mainly driven by a 10.2% increase in fees from management of accounts, a 9.9% increase in card service income and the 38.8% increase in fees from Getnet, our acquiring business mainly geared toward SME clients. The greater availability and usage of our digital platforms, better cross-selling indicators and positive trends of our Net Promoter Score also drove product usage and fees in this segment. Fees from Wealth Management increased 29.5% in 2025 compared to 2024 due to the 15.7% increase in card service income and the 182.7% increase in fees from securities intermediation in this segment. These growth rates were mainly due 77 Table of contents to an increase in sales of investment funds and greater brokerage of securities to our clients in this segment, driven by positive returns in both the equity and fixed income markets. The 20.4% increase in fees from the Middle-market segment in 2025 compared to 2024 was mainly due to a 24.7% increase in fees from guarantees and letters of credit particularly related to Stand-by Letters in line with healthy growth trends in foreign trade and exports in 2025. This was partially offset a 36.5% decrease in financial advisory fees. Fees from the Corporate Investment Banking segment decreased 13.7% in 2025 compared to 2024, mainly due a 15.9% decrease in financial advisory fees in 2025 compared to 2024. The loss in Other fees increased 29.3% mainly due to was mainly due higher fees paid for credit insurance. Net Income from Financial Operations Net income from financial operations amounted to Ch$255,782 million for the year ended December 31, 2025, an increase of 2.1% compared to the year ended December 31, 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 Ch$29,180 million increase in the results in our Financial Management Division partially offset by a Ch$23,716 million decrease in the results from our client treasury division. The following table sets forth information regarding our income (loss) from financial transactions for the years ended December 31, 2025 and 2024. Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Net income/(expense) from financial assets and liabilities for trading (43,556) 85,013 (151.2 %) Net income from derecognising financial assets and liabilities at amortised cost and financial assets at fair value through other comprehensive income 2,938 (37,068) (107.9 %) Net income from exchange, adjustment and hedge accounting of foreign exchange 296,400 202,574 46.3 % Net income from financial operations 255,782 250,519 2.1 % The net loss from financial assets and liabilities for trading at fair value through the profit and loss statement totaled Ch$43,556 million in the year ended December 31, 2025 and decreased 151.2% compared to 2024. This decrease was mainly due to a Ch$218,033 million loss from foreign currency forwards classified at fair value through profit and loss partially offset by a rise of Ch$89,464 million from other assets and liabilities classified at fair through profit and loss. The loss from foreign currency forwards classified at fair value through profit and loss was mainly due to the appreciation of the Chilean peso against the U.S. dollar in the last quarter of 2025. This was also partially offset by better results from Net income from exchange, adjustment and hedge accounting of foreign exchange which improved by Ch$117,843 million compared to 2024. 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$2,938 million in the year ended December 31, 2025 compared to a loss of Ch$37,068 million in the same period in 2024. The higher result was mainly due to a Ch$29,180 million increase in the results in our Financial 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 remain above purchase yields, this derecognition resulted in a loss in this line item in 2024, which was previously recorded as a loss in OCI in equity. Since long-term rates have fallen from previous levels and have 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$296,400 million in the year ended December 31, 2025, an increase of 46.3% compared to the gain obtained in 2024. This higher result was mainly due to the appreciation of the Chilean peso against the U.S. dollar, especially in the last quarter of 2025. The Chilean peso appreciated 9.4% in 2025 and depreciated 13.7% in 2024 against the U.S. dollar. Internal Bank policy does not allow 78 Table of contents significant foreign currency mismatches and requires that the results registered in Net income from financial operations include not only the market-to-market of our foreign currency spot position, but also the results of the derivatives used to hedge currency risk and currency exchange services. The mark-to-market of our spot position and the derivatives used to hedge foreign currency risk are classified in the line item: Net income from exchange, adjustment and hedge accounting of foreign exchange. For more details regarding our management and exposure to foreign currency risk, see “Item 11. Quantitative and Qualitative Disclosures About Market Risk—E. Market Risks—Market risk management—Market risk – local and foreign financial management.” In order to more easily compare the results from net income from financial operations, we present the following table that separates the results by lines of business for 2025 and 2024. Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Client treasury products 189,868 193,469 (1.9 %) Market-making with clients 59,780 79,895 (25.2 %) Client treasury services 249,648 273,364 (8.7 %) Sale of loans and charged-off loans 3,395 1,874 81.2 % CVA adjustments (648) 1,074 (160.3) % Financial Management Division and others(1) 3,387 (25,793) 113.1 % Non-client treasury income (loss) 6,134 (22,845) (126.9 %) Total financial transactions, net 255,782 250,519 2.1 % (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$249,648 million, a decrease of 8.7% compared to 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. In 2025, demand for these types of products on behalf of corporate clients fell as a result of reduced volatility in local and global markets. The results from client treasury, which includes the results from the sale of foreign exchange and interest rate products to clients, mainly in the Middle Market and CIB segments, decreased Ch$3,601 million in 2025 compared to 2024. The results from our market making area decreased Ch$20,115 million in 2025 compared to 2024. Market making involves providing continuous bid and offer prices in selected financial instruments, such as foreign exchange, fixed income securities, and derivatives to support client transactions and maintain market liquidity. 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$6,134 million in 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. The results of the Bank’s Financial Management Division totaled a gain of Ch$3,387 million in 2025 compared to a loss of Ch$25,793 million in 2024. In 2025, long-term interest rates fell producing higher realized gains from the sale of fixed income instruments. In 2024, as long-term interest rates remained high, the Bank carried out various liability management exercises including the unwinding of rate and currency hedges and the repurchase of its bonds. These operations help to sustain margins going forward, but in the short-term produced the aforementioned loss. 79 Table of contents Other Operating Income, Income from investments in associates and other companies and Net income form non-current assets and non-continued operations Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Income from investments in associates and other companies 9,289 10,436 (11.0 %) Net income from non-current assets and non-continued operations 7,243 4,049 78.9 % Other operating income 7,016 8,048 (12.8) % Total 23,548 22,533 4.5 % Other Operating Income, Income from investments in associates and other companies and Net income from non-current assets and non-continued operations increased by 4.5% in 2025 compared to 2024. Income from investments in associates and other companies decreased 11.0% in 2025 due to a one-time gain recognized in 2024 of Ch$1,903 million from the sale of a 1.28% stake in Cámara de Compensación de Alto Valor S.A.with no corresponding gain in 2025. Net income from non-current assets and non-continued operations increased 78.9% in 2025 compared to 2024, mainly due to higher results from the sale of fixed assets and assets received in lieu of payment. Other operating income decreased 12.8% in 2025 compared to 2024 mainly due to lower interest gained on pension plans and lower recovery of expenses compared to 2024. Operating Expenses The following table sets forth information regarding our operating expenses in the years ended December 31, 2025 and 2024. Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Personnel salaries and expenses (412,902) (398,819) 3.5 % Administrative expenses (387,605) (366,431) 5.8 % Depreciation and amortization (135,159) (141,435) (4.4 %) Impairment of property, plant and equipment (3,747) (1,295) 189.3 % Other operating expenses (101,703) (114,739) (11.4 %) Total operating expenses (1,041,116) (1,022,719) 1.8 % Efficiency ratio(1) 36.4 % 39.2 % (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 year ended December 31, 2025 increased 1.8% compared to the corresponding period in 2024 mainly due to an increase in personnel salaries and administrative expenses. The efficiency ratio improved to 36.4% in 2025 compared to 39.2% in 2024. Personnel salaries and expenses in the year ended December 31, 2025 increased 3.5% compared to the corresponding period in 2024, mainly due to the increase in inflation, as most of the wages paid by the bank pursuant to collective bargaining agreements are indexed to the Chilean CPI, and higher performance bonuses in line with better operating results. This was partially offset by the 2.6% decrease in headcount in 2025 compared to 2024. Administrative expenses increased 5.8% in the year ended December 31, 2025 compared to the corresponding period in 2024. This rise was mainly due to ongoing investments in IT, the digitalization of our banking services and data processing costs. In early 2025, the Bank transitioned most of its data processing functions to a new cloud-based server as 80 Table of contents part of the Santander Group-wide Gravity project. This resulted in higher expenses related to the changeover and write-downs and impairment recognition related to legacy systems. The growth in the client base and product usage also partially drove the rise in administrative expenses. This increase was partially offset by reductions in the Bank’s branch network. As of December 31, 2025, the Bank had a total of 229 branches which decreased 3.0% in 2025 compared to 2024. The table below provides a breakdown of the Bank’s branch network during the periods indicated. Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Traditional branches 126 133 (5.3 %) WorkCafés 94 89 5.6 % Select 9 14 (35.7 %) Total branches 229 236 (3.0 %) Total ATMs (including depositary ATMs) 2,055 2,059 (0.2 %) Depreciation and amortization expense decreased 4.4% in 2025 compared to 2024 mainly due to the lower depreciation of right of use assets in line with the reduction in our branch network and lower amortization of intangible assets that mainly include internally generated software used for the development of our digital platforms. The impairment expense increased 189.3% in 2025 compared to 2024 due to impairment of intangible assets mainly obsolete internally developed software. Other operating expenses decreased 11.4% in 2025 compared to 2024. This fall mainly corresponds to the 20.8% decrease in restructuring charges incurred in 2025 compared to 2024, which totaled Ch$34,164 million. These restructuring charges are mainly due to the on-going restructuring of our branch network and other digital transformations. This was offset by higher operating risk charge-offs and provisions that totaled Ch$48,808 million in 2025. See “Note 29—Other Operating Income and Expenses” to our Audited Consolidated Financial Statements for more detail on Other operating expenses. The following table sets forth, for the periods indicated, our personnel salaries, administrative and depreciation and amortization expenses broken down by business segment. These amounts exclude impairment and other operating expenses. Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Retail banking (744,059) (715,845) 3.9 % Wealth Management & Insurance (32,037) (33,494) (4.4 %) Middle-market (45,074) (43,343) 4.0 % Corporate Investment Banking (103,287) (97,420) 6.0 % Other (14,956) (17,878) (16.3) % Total personnel, administrative expenses, depreciation and amortization (1) (939,413) (907,980) 3.5 % (1)Excludes impairment and other operating expenses. The 3.5% increase in total costs recognized by our business segments was mainly due to greater business activity, IT investments and higher product usage. In Retail Banking, the increase was mainly due to the rise in the client base and accounts, partially offset by the positive impact on costs of less branches. Costs in the Wealth Management and Insurance segment decreased 4.4% due to efficiency driven by digital platforms. Costs in the Middle-market and CIB segments increased 4.0% and 6.0%, respectively driven by the growth of as transactional services, wages and IT investments. 81 Table of contents Provision for loan losses (P&L) The following table sets forth certain information relating to the P&L impacts of our provision for expected credit losses for the year ended December 31, 2025.

See Note 37, Risk management to our Audited Consolidated Financial Statements (2)Includes Mortgages, Consumer and Other Commercial loans. For the year ended December 31, 2025, the P&L impact of provisions for expected credit loss totaled Ch$575,198 million and increased 14.0% compared to 2024. This increase was mainly due to a rise driven by sluggish economic growth and high unemployment rates. This trend was partially offset by a 25.1% rise in recoveries of loans previously charged-off. The table below breaks down these results by main product item: Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Commercial loans (262,493) (249,593) 5.2 % Mortgage loans (85,349) (53,574) 59.3 % Consumer loans (402,695) (357,647) 12.6 % Contingent loans (13,466) 2,902 564.0 % Loans and account receivable at FVOCI (3,499) (1,040) 236.4 % Debt at FVOCI (214) (188) 13.8 % Debt at amortised cost (122) 606 120.1 % Subtotal (767,838) (658,534) 16.6 % Recovery of loans previously charged-off 192,640 153,944 25.1 % Total Provision for Loan Losses (575,198) (504,590) 14.0 % Provisions for expected credit losses of our commercial loans totaled Ch$262,493 million for the year ended December 31, 2025 and increased 5.2% compared to 2024. In commercial loans, the rise in provision for loan losses was mainly due to: (i) the sluggish growth of the economy which negatively affected specific clients in various sectors, mainly in the Middle Market segment and (ii) weakness in the agriculture sector due to negative impacts of destructive floods in 82 Table of contents certain fruit producing regions in 2023 and 2024. This drove an increase in commercial loans transferred from Stage 1 to Stage 2 and from Stage 2 to Stage 3. For the same reasons, there was a 26.4% increase in write-offs of commercial loans that totaled Ch$299,933 million representing 1.7% of total average commercial loans in 2025 compared to 1.4% in 2024. Provisions for expected credit losses for mortgage loans totaled Ch$85,349 million for the year ended December 31, 2025, and increased 59.3% compared to 2024. Total mortgage loans in 2025 decreased 0.7% in 2025 compared to 2024 as the Bank adopted a more conservative stance in terms of loan growth in this product. Persistent high unemployment levels have led to a rise in mortgage loans classified in Stage 3 by 19.5% in 2025 totaling Ch$1,018,317 million. For the same reasons, the write-off of mortgage loans increased by 41.8% to Ch$62,123 million in 2025 compared to 2024. The ratio of write-offs to average mortgage loans was 0.4% in 2025 compared to 0.3% in 2024. The provisions for expected credit losses for consumer loans totaled Ch$402,695 million and increased 12.6% in 2025. During 2025, the consumer loan book increased 2.5%, mainly driven by a rise in auto and credit card loans. This, together with persistently high levels of unemployment led to an increase of 10.3% of consumer loans classified in Stage 3. Regardless of other factors, if contractual payments are more than 30 days past due, the credit risk is deemed to have increased significantly since initial recognition and consumer loans are written off after 6 months. In 2025, write-off for this loan book decreased 1.0% and totaled Ch$349,805 million. The ratio of write-offs of consumer loans to average consumer loans reached 6.0% in 2025 compared to 6.4% in 2024. Provisions for contingent loans totaled Ch$13,466 million for the year ended December 31, 2025 compared to a provision reversal of Ch$2,902 million in 2024. Total contingent loans reached Ch$13,508,433 million in 2025 and increased 0.6% compared to 2024. This rise in contingent loans led to an increase of these loans classified in Stage 1 which resulted in a provision loss of Ch$9,549 million compared to a provision reversal of Ch$2,456 million in 2024. See “Note 24b—Contingent Loans” of the Audited Consolidated Financial Statements for more detail on contingent loans. Generally, charge-offs should be done when all collection efforts are exhausted. These charge-offs consist of derecognition from the Consolidated Statements of Financial Position of the corresponding loans operations in its entirety, and, therefore, include portions not past-due of a loan in the case of installments loans or leasing operations (no partial charge-offs exists). Subsequent payments obtained from charged-off loans will be recognized in the Consolidated Statement of Income as a recovery of loans previously charged-off. Any payment agreement of an already charged-off loan will not give rise to income-as long as the operation is still in an impaired status-and the effective payments received are accounted for as a recovery from loans previously charged-off. In general, legal collection proceedings begin with respect to consumer loans once they are past-due for at least 90 days and, with respect to mortgage loans, once they are past-due for at least 120 days. Legal collection proceedings always commence within one year of such loans becoming past-due, unless we determine that the size of the past-due amount does not warrant such proceedings. In addition, the majority of our commercial loans are short-term, with single payments at maturity. Past-due loans are required to be covered by individual loan loss reserves equivalent to 100% of any unsecured portion thereof. Recoveries on loans previously charged-off increased 25.1% in 2025 compared to 2024 as greater amounts of write-offs led to higher recoveries. There was a 26.4% increase in write-offs of commercial loans in 2025 representing 1.7% of total average commercial loans in 2025 compared to 1.4% in 2024. This increase was mainly due to (i) the sluggish growth of the economy which negatively affected specific clients in various sectors, mainly in the Middle Market segment and (ii) weakness in the agricultural sector due to the negative impacts of destructive floods in certain fruit producing regions in 2023 and 2024. Additionally, persistently high unemployment levels have led to a 41.8% rise in the write-off of mortgage loans in 2025 compared to 2024, representing 0.4% of the average mortgage loans outstanding in 2025 compared to 0.3% in 2024. In response, the Bank strengthened recovery efforts during the year, which included the relocation and restructuring of the collections department to the Risk Division. The following table shows recoveries of loans previously charged-off by type of loan. Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Recovery of loans previously charged-off Consumer loans 45,587 35,748 27.5 % Residential mortgage loans 59,271 45,486 30.3 % 83 Table of contents Commercial loans 87,782 72,710 20.7 % Total recoveries 192,640 153,944 25.1 % In some instances, we will sell a portfolio of charged-off loans to a third party. Gain (loss) on these charged-off loans is recognized as net income from financial transactions as disclosed in “Note 27—Net Income (Expense) from Financial Operations” of our Audited Consolidated Financial Statements. The following table sets forth information about our sale of charged-off loans for the years ended December 31, 2025 and 2024. Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Gains (losses) on sale of loans previously charged off 3,395 1,874 81.2 % The following table sets forth, for the periods indicated, our net provision expense broken down by business segment: Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Retail banking (498,572) (446,842) 11.6 % Wealth Management & Insurance (2,870) (2,430) 18.1 % Middle-market (74,190) (53,695) 38.2 % Corporate Investment banking 4,269 (2,995) (242.5 %) Other (3,950) 1,372 387.9 % Total provisions, net (575,313) (504,590) 14.0 % Net provision expense in retail banking increased 11.6% in 2025 compared to 2024. This increase was mainly due to the negative impact of elevated unemployment rates in the economy which has affected the consumer, mortgage and SME loan portfolios. Net provisions expense from Wealth Management increased 18.1% in 2025 compared to 2024 due to strong business growth in this segment. Loans in this segment grew 13.0% in the year . Net provision expense from the Middle-market segment increased 38.2% in 2025. This increase was mainly due to: (i) the sluggish growth of the economy which negatively affected specific clients in various sectors and (ii) weakness in the agriculture sector due to negative impacts of destructive floods in certain fruit and wine producing regions in 2023 and 2024. Net provision expense from CIB totaled a reversal of Ch$4,269 million driven by the 7.1% decrease in this segment's loan book. As of December 31, 2025, the Bank maintains post-model adjustments (overlays) totaling Ch$119,776 million to cover certain defaulted loans from mortgage and other commercial portfolios. We believe that our loan loss allowances are currently adequate for all known and expected credit losses. 84 Table of contents Income tax Year ended December 31, % Change 2025 2024 2025/2024 (in millions of Ch$) Net operating income before income tax 1,245,415 1,079,595 15.4 % Income tax expense (207,362) (219,745) (5.6 %) Effective tax rate(1) 16.7 % 20.4 % (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 2025 was Ch$207,362 million, a decrease of 5.6% compared to 2024. The decrease in income tax expenses in 2025 compared to 2024 mainly reflects the lower CPI in 2025 compared to 2024, due to the fact that our capital in our Chilean tax books is recast each year based on the variation in the CPI, which causes a tax loss, as well as timing differences between accounting and tax treatment of certain bonds. See “Note 13—Current and Deferred Taxes” of the Audited Consolidated Financial Statements for more detail on income tax expense. Therefore while, the statutory corporate tax rate in Chile in 2024 and 2025 was 27%, the Bank recognized an effective tax rate of 16.7% in 2025 compared to 20.4% in 2024. 85 Table of contents B.Liquidity and Capital Resources Sources of Liquidity The following table sets forth Santander-Chile’s contractual obligations and commercial commitments by time remaining to maturity. As of the date of the filing of this Annual Report, the Bank does not have significant purchase obligations.

(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$31,169,431 million as of December 31, 2025. Santander-Chile’s liquidity depends upon its (i) capital, (ii) reserves, and (iii) financial investments, including cash and 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$8,136,013 million as of December 31, 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. 86 Table of contents 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 retail deposits, lengthening the maturities of funding with institutional clients, and diversifying our bondholder and deposit base. Overall, the management of our liquidity and funding has led to an LCR ratio of 187.7% and a NSFR of 115.1% as of December 31, 2025. Furthermore, the Bank also has regulatory capital of Ch$7,047,321 million, representing 16.9% of our risk-weighted assets as of December 31, 2025.

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: (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. 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 Chilean Central Bank bonds and treasury notes issued locally and abroad.

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. 88 Table of contents Debt financial instruments at fair value through other comprehensive income (FVOCI) – under IFRS 9 As of December 31, 2025, 2024 and 2023, the debt instruments at fair value through other comprehensive income (FVOCI) in accordance with IFRS 9 are as follows: As of December 31 2025 2025 2024 2023 (in millions of Ch$) Chilean Central Bank and government securities Chilean Central Bank financial instruments — 199,903 2,286,541 Chilean Treasury bonds and notes 2,825,238 1,273,701 737,705 Other Chilean government financial instruments — — 454 Subtotal 2,825,238 1,473,604 3,024,700 of which sold under repurchase agreement 1,789,703 397,334 207,280 Other Chilean debt financial securities Chilean Bank debt financial instruments 3,484 5,006 6,656 Other Chilean financial instruments — — — Subtotal 3,484 5,006 6,656 of which sold under repurchase agreement — — 91 Foreign financial securities Foreign Central Banks debt financial instruments 769,644 1,001,105 1,238,866 Other foreign financial instruments — 207,770 265,803 Subtotal 769,644 1,208,875 1,504,669 of which sold under repurchase agreement — — 127,752 Total 3,598,366 2,687,485 4,536,025 (c)Fair Value through Profit or Loss (FVTPL) Financial assets that do not contain contractual terms that give rise on specified dates to cash flows that are SPPI, or if the financial assets, or if the financial asset is not held in a business model that is either (i) a business model to collect the contractual cash flows or (ii) a business model that is achieved by both collecting contractual cash flows and selling.

(See “Item 5. Operating and Financial Review and Prospects—B. 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 uses as its 91 Table of contents liquidity portfolio those defined by the FMC and the Central Bank, which are in line with those established in BIS III. As of December 31, 2025 and 2024, the breakdown of the Bank’s liquid assets by levels was the following: December 31, 2025 December 31, 2024 (Ch$ million) (Ch$ million) Balance as of: Cash and cash equivalent 1,904,994 2,416,812 Level 1 liquid assets (1) 6,227,856 7,241,318 Level 2 liquid assets (2) 3,163 4,517 Total liquid assets 8,136,013 9,662,647 (1)Includes available balances held in the Central Bank of Chile, financial instruments issued by the Chilean Treasury or Central Bank and other financial instruments issued or guaranteed by states, multilateral development banks or foreign central banks that have a first class rating, in accordance with international rating agencies.

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.” 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 11. Quantitative and Qualitative Disclosures About Market Risk.” 92 Table of contents 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 Ley General de Bancos and the Ley de Sociedad Anónimas regarding loans to related parties and minimum dividend payments. See our Consolidated Statements of Cash Flows in our Audited Consolidated Financial Statements for a detailed breakdown of the Bank’s cash flow.

As of December 31, 2025, the Bank’s top 20 time deposits represented 20.0% of total time deposits, or 4.8% 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. The liquidity coverage ratio (“LCR”), which measures the short-term resistance of Banks’ liquidity risk profile to ensure that organizations have an adequate pool of unencumbered, high-quality liquid assets, which can be readily and immediately converted to cash in private markets, in order to meet short-term liquidity needs. As of December 31, 2025, our LCR was 187.7%. The net stable funding ratio (“NSFR”) which measures a bank’s stable funding sources over required stable needs was 115.1% as of December 31, 2025. 94 Table of contents Composition of Deposits The following table sets forth the composition of our deposits and similar commitments at December 31, 2025, 2024, 2023, 2022, and 2021. 2025 2024 2023 2022 2021 (in millions of Ch$) Demand deposits and other demand obligations Current accounts 11,674,317 11,898,457 11,014,748 11,711,969 14,385,633 Other deposits and demand accounts 966,621 915,917 854,595 1,016,896 1,773,233 Other demand obligations 1,434,652 1,446,235 1,668,483 1,357,361 1,742,072 Subtotals 14,075,590 14,260,609 13,537,826 14,086,226 17,900,938 Time deposits and other time deposits Time deposits 16,216,079 16,867,607 15,939,325 12,779,206 9,926,507 Time saving accounts 269,821 221,973 189,757 191,257 195,570 Other time deposits 7,883 9,045 8,860 8,327 8,978 Subtotals 16,493,783 17,098,625 16,137,942 12,978,790 10,131,055 Total deposits and other commitments 30,569,373 31,359,234 29,675,768 27,065,016 28,031,993 Maturity of Interest Bearing Deposits The following table sets forth information regarding the currency and maturity of our interest bearing deposits as of December 31, 2025, expressed in percentages of our total deposits in each currency category.

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 December 31, 2025, 2024 and 2023: As of December 31, 2025 2024 2023 (in millions of Ch$) Personal guarantees 556,196 365,932 494,104 Letter of credits of merchandise traffic operations 249,140 308,407 262,496 Transactions related to contingent events 1,871,802 2,208,507 1,641,510 Unrestricted prompt cancel credit lines 10,584,496 10,352,459 9,490,141 Other credit commitments 246,799 195,207 314,318 Total 13,508,433 13,430,512 12,202,569 Asset and Liability Management Please refer to “Item 11.

During 2025, the Bank focused its investments in the ongoing investments in IT and the digitalization of our banking services and expanding the WorkCafé network. In early 2025, the Bank transitioned most of its data processing functions to a new cloud-based server as part of the Group-wide Gravity project. C.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 5. 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 5. Operating and Financial Review and Prospects—A. 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 form 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 104 Table of contents requirements and to facilitate international business, rather than to earn income. See Note 1—Summary of Significant Accounting Policies—(k) Recognizing Income and Expenses to our Audited 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 years ended December 31, 2025, 2024 and 2023. 105 Table of contents As of December 31, 2025 2024 2023 Average Balance Interest Earned Average Nominal Rate Average Balance Interest Earned Average Nominal Rate Average Balance

Loan Portfolio Loan Categories Our loan categories are as follows: Interbank loans Interbank loans 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 Commercial loans 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.$. The interest on these loans is fixed or variable and is used primarily to finance working capital or investments. General commercial loans also include factoring operations. Foreign trade loans are fixed rate, short-term loans made in foreign currencies (principally U.S.$) to finance imports and exports. Checking account debtors 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. Credit card debtors includes credit card balances from businesses subject to nominal fixed rate interest charges. 113 Table of contents Factoring transactions mainly include short-term loans to companies with a fixed monthly nominal rate backed by a company invoice. Leasing transactions are agreements for the financial leasing of capital equipment and other property. Student loans 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. Other loans and accounts receivable loans include other commercial loans and accounts payable not included in any of the categories above. Mortgage loans Loans with mortgage finance bonds 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 Chilean banking regulations. 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. Endorsable mortgage mutual loans 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. Mortgage mutual financed with mortgage bond 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. Other mortgage mutual loans 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. Other loans and accounts receivable loans include other mortgage loans and accounts payable not included in any of the categories above. Consumer loans Installment consumer loans 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.
