BANCO SANTANDER CHILE INTERIM CONSOLIDATED FINANCIAL STATEMENTS For the periods ending on June 30, 2026, and 2025 and December 31, 2025
INDEPENDENT AUDITOR’S REVIEW REPORT Santiago, July 28, 2026 To the Shareholders and Directors Banco Santander-Chile Introduction We have reviewed the accompanying interim consolidated statement of financial position of Banco Santander-Chile and subsidiaries as of June 30, 2026, and the related interim consolidated statements of income and other comprehensive income for the three- and six- month periods ended June 30, 2026, the interim consolidated statements of changes in equity and of cash flows for the six-month period then ended, and the notes to the interim consolidated financial statements, including information on significant accounting policies. Management is responsible for the preparation and fair presentation of this consolidated financial information in accordance with the accounting standards and instructions issued by the Financial Market Commission. Our responsibility is to express a conclusion on this interim consolidated financial information based on our review. Scope of the review We have conducted our review in accordance with the Standard on Review Engagement 2410 “Review of interim financial information performed by the independent auditor of the entity”. A review of interim financial information consists mainly of making inquiries with those responsible for financial and accounting matters, as well as applying analytical procedures and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Generally Accepted Auditing Standards in Chile, and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Consequently, we do not express an audit opinion.
Santiago, July 28, 2026 Banco Santander-Chile 2 Conclusion Based on our review, we have not become aware of any matter that causes us to believe that the accompanying interim consolidated financial information does not present fairly, in all material respects, the interim consolidated financial position of the entity as of June 30, 2026, its results for the three- and six-month periods ended June 30, 2026, and its cash flows for the six-month period then ended, in accordance with the accounting standards and instructions issued by the Financial Market Commission.

NOTE 01 - CORPORATE INFORMATION Banco Santander-Chile is a banking corporation organized under the laws of the Republic of Chile, supervised by the Financial Market Commission (FMC). It is also subject to the regulations of the Securities and Exchange Commission of the United States of America (SEC), considering the Bank is listed on the New York Stock Exchange (NYSE) through an American Depositary Receipt (ADR) program. Banco Santander Spain controls Banco Santander Chile through its shareholdings in Teatinos Siglo XXI Inversiones S.A. and Santander Chile Holding S.A., both subsidiaries controlled by Banco Santander Spain. As of June 30, 2026, Banco Santander Spain directly or indirectly owns 99.8% of Santander Chile Holding S.A. and 100% of Teatinos Siglo XXI Inversiones S.A., which allows Banco Santander Spain control over 67.18% of the Bank's shares. The Bank provides its clients with a wide range of general banking services, from individuals to large corporations. In addition, Banco Santander-Chile and its affiliates (collectively referred to as 'Bank' or 'Santander-Chile' hereafter) offer consumer and commercial banking services, as well as other services, including factoring, collections, leasing, securities and insurance brokerage, brokerage of mutual and investment fund and investment banking. The Bank's legal address is Calle Bandera No 140 Santiago de Chile, and its website is www.santander.cl. NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 1. Preparation basis These Interim Consolidated Financial Statements have been prepared following the Compendium of Accounting Standards for Banks (CASB), in its version applicable as of January 2022, as well as the instructions issued by the FMC. The FMC, under Law No 21,000, provides in numeral 6 of article 5 that the Financial Market Commission may set the rules for the preparation and presentation of the annual reports, balance sheets, statements of financial position and other financial statements of the supervised entities and determines the principles according to which companies must keep their accounts. Regarding all matters that are not covered by this regulation, if they do not conflict with its instructions, then they must adhere to generally accepted accounting criteria corresponding to the technical standards issued by the Chilean Association of Accountants AG, which coincide with the International Financial Reporting Standards (IFRS) agreed by the International Accounting Standards Board (IASB). In case of discrepancies between the accounting principles and the accounting criteria issued by the FMC in its Compendium of Accounting Standards for Banks and instructions, the latter shall prevail. The Bank uses certain currency terms and conventions for these Interim Consolidated Financial Statements. Thus, 'USD' stands for 'US dollar', 'EUR' stands for 'euro', 'CNY' stands for 'Chinese yuan', 'JPY' stands for 'Japanese yen', 'CHF' stands for 'Swiss franc', 'AUD' stands for 'Australian dollar' and 'UF' stands for 'Unidad de Fomento de Chile'. The notes in the Interim Consolidated Financial Statements contain information in addition to that presented in the Interim Consolidated Statements of Financial Position, Interim Consolidated Statements of Income, Interim Consolidated Statements of Other Comprehensive Income,Interim Consolidated Statement of Change in Equity and Interim Consolidated Statement of Cash Flows. They provide narrative descriptions or disaggregation of such states in a clear, relevant, reliable and comparable manner. 2. Preparation of the Interim Consolidated Financial Statements The Interim Consolidated Financial Statements as of June 30, 2026, and 2025, and December 31, 2025 incorporate the individual financial statements of the Bank and its controlled entities (affiliates) and include the adjustments, reclassifying and eliminations necessary to comply with the accounting and measurement criteria established by IFRS 10 'Consolidated Financial Statements'. Control is achieved when the Bank: i. Has power over the investee (that is, it has rights that grant it the present capacity to manage the relevant activities of the investee); ii. Has exposure or rights to variable returns from its involvement with the investee; and iii. Has the ability to use its power over the investee to influence the amount of the investor's returns. The Bank reassesses whether it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. For example, when the Bank has less than most of the voting rights in an investee, but those voting rights are sufficient to have the ability to direct the relevant activities, then it is concluded that the Bank has control. The Bank considers all relevant facts and circumstances in assessing whether the Bank's voting rights in an investee are sufficient to give it power. These include: Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 12
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued • The size of the Bank's holding of voting rights relative to the size and dispersion of holdings of the other vote holders. • The potential voting rights held by the Bank, other vote holders or other parties. • The rights arising from other contractual agreements. • Any additional facts and circumstances that indicate that the Bank has or does not have the current ability to direct the relevant activities when decisions need to be made, including voting patterns at previous shareholders' meetings. Consolidation of a subsidiary begins when the Bank obtains control of the subsidiary and ceases when the Bank cedes control. Specifically, the income and expenses of a subsidiary acquired or disposed of during the period are included in the Interim Consolidated Statements of Income and Interim Consolidated Statements of Other Comprehensive Income from the date the Bank gains control until the date the Bank ceases to control the subsidiary. Profit or loss alongside each component of the Interim Consolidated Statements of Other Comprehensive Income is attributed to the Bank's holders and non-controlling interest. The total comprehensive income of subsidiaries is attributed to the owners of the Bank and the non-controlling interests, even if this results in the non-controlling interests having a deficit in certain circumstances. When necessary, adjustments are made to the financial statements of the subsidiaries to ensure their accounting standards are consistent with the Bank's accounting standards. All balances and transactions between consolidated entities are eliminated. Changes in the consolidated entities' participation that do not result in the loss of control are accounted for as equity transactions. Accordingly, the book value of the Bank’s equity holders and the non-controlling interests are adjusted to reflect the changes in participation over subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration being paid or received is recognized directly in equity and attributed to the equity owners of the Bank. The non-controlling interest represents the participation of third parties in the Bank's consolidated equity, which is presented in the Interim Consolidated Statement of Change in Equity. Their share of the result for the year is shown as 'Profit attributable to non- controlling interest' in the Interim Consolidated Statements of Income. The following table shows the composition of the entities over which the Bank can exercise control and, therefore, form part of the consolidation perimeter: i.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued ii. Entities controlled by the Bank through other considerations and Associates The following companies have been consolidated based on the fact that the Bank determines their relevant activities (these are companies complementary to the banking sector) and, therefore, over which the Bank exercises control: • Santander Gestión de Recaudación y Cobranza Limitada: its exclusive activity is administering and collecting loans. • Multiplica SpA: its primary purpose is the development of incentive programs that encourage the use of payment cards. An associate is an entity over which the Bank can exercise significant influence but not control or joint control. This capacity is usually manifested in a 20% or more interest in the entity's voting rights and is accounted for using the equity method in accordance with IAS 28 ‘Investments in Associates and Joint Ventures’. The following entities in which the Bank has an interest and are recognized using the equity method are considered 'associates': Place of incorporation and operation % of ownership As of June 30, As of December 31, As of June 30, Name of associated entity Main Activity 2026 2025 2025 Redbanc S.A.

Share or rights in other companies Entities over which the Bank has no control or significant influence are presented in this category. These equity instruments must be measured at fair value in compliance with IFRS 9 ‘Financial Instruments’. Nevertheless, the Bank may consider the cost an appropriate fair value estimate in concrete circumstances. This may be the case if the most recently available information is insufficient to measure the fair value or if a wide range of possible fair value measurements and the cost involved represents the best estimate of fair value within that range. Additionally, the Bank may make an irrevocable decision to present subsequent changes to the fair value in other comprehensive income during its initial recognition. Subsequent changes in this valuation shall be recognized in 'Accumulated other comprehensive income - Items that will not be reclassified to profit or loss'. Dividends received from these investments are recorded in the Interim Consolidated Statements of Income under 'Result from investments in companies'. These instruments are not subject to the IFRS 9 ‘Financial Instruments’ impairment model.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued 3. Non-controlling interest Non-controlling interest represents the portion of net income and net assets the Bank does not own, either directly or indirectly. It is presented separately in the Interim Consolidated Statements of Income and separately from the equity in the Interim Consolidated Statements of Financial Position . In the case of entities controlled by the Bank through other considerations, profits and equity are presented as a non-controlling interest. This is because the Bank controls them, but has no percentage ownership in them. 4. Reporting segments The Bank's operating segments are those units whose operating results are reviewed regularly by the highest level of management regarding decision-making. Accordingly, two or more operating segments can be added into one only when the aggregation is consistent with the basic principle under the IFRS 8 'Operating Segments' and if the segments have similar economic characteristics and are alike in each one of the following aspects: i. The nature of the products and services. ii. The nature of production processes. iii. The type of customer category for which its products and services are intended. iv. The methods used to distribute their products or provide services. v. If applicable, the nature of the regulatory framework, e.g., banking, insurance, utilities. The Bank reports separately for each operating segment that meets any of the following quantitative thresholds: i. Its reported revenues from ordinary activities, including both sales to external clients and inter-segment sales or transactions, equal or exceed 10% of the combined revenues from all operating segments' ordinary internal and external activities. ii. The amount of its reported results is, in absolute terms, equal to or greater than 10% of the greater of (i) the combined profit reported by all operating segments that have not reported a loss; and (ii) the combined loss reported by all operating segments that have reported a loss. iii. Its assets equal or exceed 10% of the combined assets of all operating segments. Operating segments that do not meet any of the quantitative thresholds may be considered reportable segments. The information must be disclosed separately if management believes it would be helpful to Interim Consolidated Financial Statements users. Concerning the above, the Bank's segments were obtained under the consideration that an operating segment is a component of an entity that: i. Engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses from transactions with other elements of the same entity). ii. Whose operating results are regularly reviewed by the entity's chief executive officer, who makes decisions about resources allocated to the segment and assesses its performance. iii. For which separate financial information is available 5. Functional and presentation currency The Bank, in according to IAS 21 'The Effects of Changes in Foreign Exchange Rates', has defined the Chilean Peso as its functional and presentation currency, as this is the currency of the primary economic environment in which the Bank operates, as well as the currency that influences the cost and revenue structure. Therefore, all balances and transactions denominated in currencies other than the Chilean Peso are considered 'foreign currency'. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 15
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued 6. Transaction in foreign currencies The Bank conducts transactions in amounts denominated in foreign currencies, mainly US dollars. The assets and liabilities denominated in foreign currencies held by the Bank and its affiliates are translated into Chilean Pesos at the market exchange rate corresponding to the end of the reported month (spot rate), which amounts to $921.09 per US$1 for June 2026 and $931.50 per US$1 for June 2025 and $900.69 per US$1 for December 31, 2025. For all other currencies, an external pricing provider is used. The net foreign exchange gain and loss includes recognizing the effects of exchange rate changes on assets and liabilities denominated in foreign currencies and the profit and loss on foreign exchange spot and forward transactions undertaken by the Bank. 7. Cash and cash equivalents The indirect method is used to prepare the Interim Consolidated Statement of Cash Flows, starting with the Bank's consolidated pre- tax income, and then incorporating non-cash transactions, cash-flow-related income, and expense of activities classified as investments or financing. The following items are taken into consideration in the preparation of the Interim Consolidated Statement of Cash Flows: i. Cash flows: inflows and outflows of cash and cash equivalents, defined as balances in items such as deposits with the Central Bank of Chile, deposits in domestic banks and deposits abroad. ii. Operating activities: these are the normal activities carried out by banks alongside other activities that cannot be classified as investments or financing. iii. Investing activities: these correspond to the acquisition, sale or disposal by other means of long-term assets and other investments not included in cash and cash equivalents. iv. Financing activities: those that result in changes to the size and composition of equity and liabilities that are not part of operating or investing activities. 8. Definitions, classification and measurement of financial assets/liabilities i. Definitions A 'financial instrument' is any contract that gives rise to a financial asset in an entity and a financial liability or equity instrument in another entity. A 'financial asset' is any asset that is: (a) cash; (b) an equity instrument of another entity; (c) a contractual right to receive cash or another financial asset from another entity or to exchange financial assets or financial liabilities with another entity under conditions that are potentially favorable to the entity; or (d) a contract that will or may be settled using the entity's own equity instruments. A 'financial liability' is any liability that is: (a) a contractual obligation to deliver cash or another financial asset to another entity or to exchange financial assets or financial liabilities with another entity under conditions that are potentially unfavorable to the entity; or (b) a contract that will or may be settled using the entity's equity instruments. An 'equity instrument' is any contract that evidences a residual interest in the assets of the issuing entity after deducting all of its liabilities. A 'financial derivative' is a financial instrument whose value fluctuates in response to changes concerning an observed market variable (such as an interest rate, a foreign exchange rate, a financial instrument's price, or a market index, including credit ratings), whose initial investment is minimal compared with other financial instruments with a similar response to changes in market factors, and which is generally settled at a future date. 'Fair value' is the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants at the measurement date.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued ii. Initial recognition The Bank shall recognize a financial asset or financial liability only when it becomes part of the contractual terms of the instrument (rights and obligations). A conventional purchase or sale of financial assets shall be recognized using the accounting contract date or settlement date. iii. Classification of financial assets/liabilities Classification of financial assets Financial assets shall be classified into measurement categories based on the entity's business models for managing the financial assets and the contractual cash flow characteristics of said assets. The business model refers to how the Bank manages its financial assets to generate cash flows. In other words, the entity's business model determines whether the cash flows will come by obtaining contractual cash flows, selling financial assets, or both. Assessing the contractual flow characteristics (SPPI test) requires determining whether the asset's contractual flows are solely payments of principal on specified dates and interest on the principal outstanding amounts in the currency in which the financial asset is denominated. The principal is the fair value of the financial asset at initial recognition. Nevertheless, the principal amount may change over the life of the financial asset (if there are principal repayments). Interest is the compensation received for the time value of money and the credit risk related to the principal amount owed over a specified period, alongside other risks and administrative costs, and a profit margin. For the assessment, the Bank conducts a test evaluating whether the contractual flows meet the criteria for a core lending arrangement. The Bank uses its professional assessment and considers relevant factors such as currency, interest rate (fixed or variable) and the period it sets. The assessment of business models is not an instrument-by-instrument ranking approach but at a higher level of aggregation and considers all relevant evidence: model performance, risks affecting performance, and how managers are rewarded, among others. According to the above, the objectives of the business models are: • To hold assets to collect cash flows – through management that produces cash flows by collecting contractual payments throughout the instrument's life. Models with this goal allow for sales if they are infrequent (even if significant in value) or insignificant in value both individually and in aggregate (even if frequent), and even more so if they result from a substantial increment in risk or the risk management of credit concentration. • To maintain financial assets for collection and sale. Per this objective, the entity's key management personnel have decided that the supply of contractual cash flows and the sale of financial assets are essential to achieve the business model's goal. Therefore, there is a higher frequency and value of sales for this purpose. • Other models - financial assets are measured at fair value through profit or loss if they are not held within a business model whose objective is to hold the assets to collect contractual cash flows or if their objective is achieved by obtaining contractual cash flows and selling financial assets. Assets are managed on a sales basis, and decisions are made on a fair value basis. In accordance with the above, the Bank will classify its financial assets based on whether they are subsequently measured at amortized cost, at fair value through other comprehensive income, or at fair value through profit or loss. Additionally, an irrevocable election may be made at the time of initial recognition of investments in equity instruments to present subsequent changes in fair value in other comprehensive income. Classification of financial liabilities An entity shall classify all financial liabilities as subsequently measured at amortized cost, except for derivative liabilities which shall be measured at fair value through profit or loss.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued Reclassifications Reclassifying financial assets only occurs only when the business model for managing financial assets has changed. These changes are determined by top management due to external or internal changes. Financial liabilities are not reclassified. iv. Measurement of financial assets/liabilities Initial measurement Financial assets and liabilities are initially measured at fair value (transaction price), plus or minus transaction costs in the case of a financial asset or financial liability that is not carried at fair value through profit or loss. Subsequent measurement of financial assets A financial asset shall subsequently be measured according to the following: 1. Amortized cost A financial asset is measured at amortized cost if the financial asset is held within a business model whose objective is to hold financial assets to earn cash flows, and the contractual terms of the financial asset give rise, at specified dates, to cash flows that are solely payments of principal and interest on the outstanding principal amount. Interest income shall be calculated using the effective interest method. This method applies to financial assets and liabilities measured at amortized cost (interest income and interest expense). The effective interest rate is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial asset or financial liability to the gross carrying amount of the financial asset or the amortized cost of a financial liability. 2. Fair value through other comprehensive income A financial asset is measured at fair value through other comprehensive income if the financial asset is held within a business model in which the objective are to obtain the contractual cash flows, to sell financial assets, and if the contractual terms of the financial asset give rise, at specified dates, to receive cash flows that are solely payments of principal and interest on the outstanding principal amount. 3. Fair value through profit or loss A financial asset is measured at fair value through profit or loss unless measured at amortized cost or fair value through other comprehensive income. 4. Irrevocable election to measure at fair value with changes in other comprehensive income Upon the initial recognition of Investments in equity instruments, a determination may be held to present subsequent changes in fair value in other comprehensive income that would otherwise be measured at fair value through profit or loss when not held for trading, except for dividend income, which is recognized in profit or loss for the period. Gains or losses arising from the derecognition of these equity instruments are not transferred to profit or loss. Subsequent measurement of financial liabilities Financial liabilities are subsequently measured at amortized cost, except for derivatives measured at fair value through profit or loss. v. Derecognition of financial assets/liabilities A financial asset shall be derecognized when and only when: (i) The contractual rights to the cash flow from the financial asset expire, or (ii) The contractual rights to receive the cash flows of a financial asset are transferred, or it retains the contractual rights to receive the cash flows of a financial asset but assumes a contractual obligation to pay them to one or more recipients. In this sense, if the risks and rewards of ownership of the financial asset are substantially transferred, the financial asset is derecognized.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued In the case of unconditional sales, sales under repurchase agreements at fair value at the date of repurchase, sales of financial assets with a purchased call option or a written put option that is deeply out of the money, uses of assets where the transferor does not retain subordinated financing nor grants any credit enhancement to the new owners, and other similar cases, the transferred financial asset is recognized from the Interim Consolidated Statements of Financial Position with simultaneous recognition of any rights or obligations retained or created as a result of the transfer. In the case of sales of financial assets: (i) under fixed-price repurchase agreements or using the sale price plus interest, (ii) of securities lending agreements in which the borrower must return the same or (iii) similar assets and in other akin cases, the transferred financial asset is not recognized from the Interim Consolidated Statements of Financial Position and continues to be measured using the same criteria as before the transfer. A financial liability is derecognized when and only when it is extinguished – that is, when the obligation specified in the contract is paid for, cancelled or expired. In the case of loans, the FMC requirements for recognition applies. See letter o), VIII. vi. Offsetting a financial asset with a financial liability A financial asset and a financial liability shall be offset and presented by their net amount in the Interim Consolidated Statements of Financial Position when, and only when, there is a legally enforceable right to set off the recognized amounts and an intention to settle the net amount or to realize the asset and settle the liability, simultaneously. As of June 30, 2026, and 2025, and December 31, 2025 , the Bank has no financial asset/liability that offset. 9. Financial derivatives and hedge accounting Derivatives are classified as either trading instruments or hedging instruments. The Bank uses financial derivatives for the following purposes: i. To provide such instruments to customers who request them to manage their market and credit risks. ii. To use them for the risk management of the proprietary position of the Bank's entities and their assets and liabilities ('hedging derivatives'). iii. To benefit from changes in the value of these derivatives (trading derivatives). Trading derivatives are measured at fair value through profit or loss and are presented as assets/liabilities according to their positive or negative fair value. Derivatives that do not qualify as hedging instruments are accounted for as trading instruments. Hedge accounting aims to reflect in the financial statements the effect of an entity’s risk management activities that use financial instruments to manage exposures arising from specific risks that could affect profit or loss for the period or other comprehensive income. During the 2025 financial year, the Bank began applying the requirements established in IFRS 9- Financial Instruments for hedge accounting relationships. The main impacts of this change on hedge accounting are primarily related to: • the incorporation of credit risk dominance analysis and the economic relationship in effectiveness assessment • the updating of formal hedge documentation • the recognition of a hypothetical derivative representing the portion of the mark-to-market (MTM) corresponding to the risk being hedged in the hedged item for micro cash flow hedges. The hypothetical derivative replaces the previously recognized fictitious derivative For a hedging relationship to meet the requirements established in IFRS 9- Financial Instruments, it must comply with the following conditions: • Eligible hedging instruments: All derivative financial instruments or non-derivative financial instruments measured at fair value through profit or loss, or combinations thereof. In the case of foreign exchange risk hedges, any type of non-derivative financial instrument may also be designated, regardless of its measurement criteria. • Eligible hedged items: Recognized assets or liabilities, firm commitments, highly probable forecast transactions, and net investments in foreign operations. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 19
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued • Documentation: At the inception of the hedge, a formal designation and documentation of the hedging relationship must be prepared, including the entity’s risk management objective and strategy, identification of the hedging instrument and hedged item, the nature of the hedged risk, the methodology for measuring effectiveness (including analysis of sources of ineffectiveness), and the hedge ratio. The main sources of ineffectiveness based on the hedged risk are: • Interest rate risk: mismatches in time horizons, principal amounts, repricing and payment dates, time value of options, and modifications to the hedged item or hedging instrument. • Foreign exchange risk: in addition to the above, differences between the interest rates of the two currencies representing the net cost or benefit of exchanging cash flows between currencies with different interest rates. • Effectiveness: The hedging relationship must be effective, which requires the existence of an economic relationship between the hedged item and the hedging instrument, that credit risk does not dominate value changes, and that the hedge ratio is consistent with that used in the entity’s risk management. The implementation of IFRS 9- Financial Instruments for hedging relationships designated prior to December 31, 2024, did not have a material impact on the Interim Consolidated Statement of Financial Position or the Interim Consolidated Statement of Income. As of December 31, 2025, the impact on profit or loss amounted to Ch$2,401 million. The Bank assesses these effectiveness requirements through: • Demonstrating the economic relationship between the hedged item and the hedging instrument through a qualitative test, and, if not met, through quantitative tests comparing the market value of the hedged items (for the hedged risk) and the hedging instruments. Prospectively, a quantitative analysis of changes in market values is also performed. • Calculating the hedge ratio based on the quantity of hedged items actually hedged and the quantity of hedging instruments actually used. • Assessing credit risk dominance through analysis of the credit exposure of both hedged items and hedging instruments. Hedge accounting derivatives are classified and recognized based on the type of risk they hedge, in accordance with the following criteria: Fair value hedges: These hedge exposures to changes in the fair value of a hedged item attributable to a specific risk. Gains or losses arising from both the hedging instruments and the hedged items (for the hedged risk) are recognized directly in the Interim Consolidated Statements of Income. When a fair value hedge is discontinued, previously recognized adjustments to the hedged item are amortized to profit or loss using the recalculated effective interest rate from the date hedge accounting ceases and must be fully amortized by maturity. In accordance with paragraph 6.1.3 of IFRS 9- Financial Instruments, the Bank continues to account for fair value macro-hedges under IAS 39. Accordingly, gains or losses on hedging instruments are recognized directly in the Interim Consolidated Statements of Income, while gains or losses arising from changes in the fair value of the hedged amount (attributable to the hedged risk) are recognized in profit or loss with a corresponding entry in “Changes in the fair value of hedged items” of a portfolio hedge of interest rate risk (asset or liability), as appropriate. Cash flow hedges: These hedge exposures to variability in cash flows attributable to a specific risk associated with the hedged item. The effective portion of changes in the value of the hedging instrument is temporarily recognized in equity, under “Other comprehensive income – Items that may be reclassified to profit or loss – Hedging derivatives. Cash flow hedges (effective portion)” until the hedged item affects profit or loss. At that point, it is recognized in the Interim Consolidated Statements of Income in the same period as the hedged item, unless it is included in the cost of a non-financial asset or liability, or when forecast transactions result in the recognition of non-financial assets or liabilities. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 20
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued When cash flow hedges are discontinued, the cumulative gain or loss recognized in equity (while the hedge was effective) continues to be recognized there until the hedged transaction occurs, at which point it is recognized in profit or loss, unless the transaction is no longer expected to occur, in which case it is recognized immediately in profit or loss. The Bank discontinues hedge accounting when the hedging instrument expires, is sold, or when the hedging relationship becomes ineffective because it is no longer aligned with the risk management objective. In such cases, the derivative is thereafter accounted for as a trading derivative. If a hedging relationship ceases to meet effectiveness requirements but the risk management objective remains unchanged, the Bank will assess whether to rebalance or adjust the hedge ratio to meet effectiveness requirements again without discontinuing the hedging relationship. A hedging instrument is generally designated in its entirety, as the factors contributing to its fair value are interdependent. However, IFRS 9 allows certain components to be excluded from designation: 1. Separating the intrinsic value and time value of an option and designating only the intrinsic value as the hedging instrument (mandatory if intrinsic value is designated); 2. Separating the forward element and spot element of a forward contract and designating only the spot element as the hedging instrument (determined per hedging relationship); and 3. Separating the foreign currency basis spread of a currency derivative and excluding it from designation (determined per hedging relationship). Separating these components improves hedge effectiveness and allows alternative accounting treatment for excluded components, whereby changes in value are recognized in “Accumulated other comprehensive income – Non-designated items” and subsequently recognized in profit or loss depending on the nature of the hedged item, either over time or when the hedged transaction occurs. Additionally, if the entity manages the credit risk of all or part of a financial instrument using credit derivatives, it may designate a credit exposure at fair value through profit or loss, provided that the derivative matches the name and seniority of the instrument being hedged. This designation may be made at initial recognition or subsequently, with proper documentation. From designation onward, all fair value changes (not only those related to credit risk) are recognized in the Interim Consolidated Statements of Income. Embedded derivatives in hybrid financial instruments “Embedded derivatives” are a component of a hybrid contract that simultaneously includes a non-derivative host contract together with a financial derivative that is not separately transferable and has the effect that some of the cash flows of the hybrid contract vary in the same manner as the embedded derivative would if considered on a stand-alone basis. As of June 30, 2026, and 2025, and December 31, 2025, Banco Santander-Chile maintains embedded derivatives in its portfolio within contracts known as Dual Currency, which are accounted for as options within the trading derivatives portfolio. 10. Fair value of financial assets and liabilities No transaction costs are deducted when financial assets and liabilities are measured at fair value. Assets and liabilities subsequently measured at amortized cost are not required to be measured at fair value. 'Fair value' is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction in the principal market at the measurement date under current market conditions (i.e., an exit price) regardless of whether that price is directly observable or estimated using another valuation technique. Fair value measurement is for a specific asset or liability. Therefore, in measuring fair value, the Bank considers the characteristics of the asset or liability in the same way that market participants would consider in pricing the asset or liability at the measurement date. In addition, the fair value measurement assumes that the transaction of selling the asset or transferring the liability takes place either: (a) in the principal market for the asset or liability or (b) in the absence of a principal market, the most advantageous market for the asset or liability. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 21
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued When there is no market price for a given financial instrument, its fair value is estimated based on the price established in recent transactions involving similar instruments or, in the absence thereof, based on valuation models sufficiently contrasted by the international financial community, considering the specific peculiarities of the instrument to be valued and especially, the different types of risk related to the instrument. When valuation techniques are used, they maximize the use of the relevant observable input data and minimize that of unobservable input data. For example, when an asset or a liability measured at fair value has a bid price and an asking price, the price within the bid-ask spread that is most representative of fair value in the circumstances shall be used to measure fair value regardless of where the input is categorized within the fair value hierarchy. Although average prices are allowed as a practical resource to determine the fair value of an asset or a liability, the Bank makes an adjustment (FVA or fair value adjustment) when there is a gap between the purchase and sale price (close-out cost). All derivatives are recorded in the Interim Consolidated Statements of Financial Position at fair value from the trade date. If their fair value is positive, they shall be recorded as an asset; if their fair value is negative, they shall be recorded as a liability. In the absence of evidence to the contrary, the trade date's fair value is deemed the transaction price. Changes in the fair value of derivatives from the trade date are recognized with a balancing entry in the Interim Consolidated Statements of Income under "Profit/(loss) on financial assets/liabilities held for trading at fair value through profit or loss". Specifically, the fair value of financial derivatives included in trading portfolios is based on their daily market quotation and, if for exceptional reasons a market quotation cannot be determined on a given date, valuation techniques similar to those used for derivatives contracted in over-the-counter (OTC) markets are applied. The fair value of these derivatives is determined as the sum of the future cash flows arising from the instrument, discounted to the valuation date (“present value” or “theoretical close”), using valuation methodologies recognized in the financial markets, including “net present value” and option pricing models, among other methods. In addition, the fair value of derivatives includes valuation adjustments reflecting the credit risk of the transaction, whether the Bank’s own credit risk (DVA) or that of the counterparty (CVA), with the objective that the fair value of each instrument incorporates both counterparty credit risk and the Bank’s own credit risk. Counterparty Credit Risk (CVA) is a valuation adjustment applied to derivatives contracted in over-the-counter markets as a result of exposure to counterparty credit risk. Liquidity Valuation Adjustment (LVA) has also become a key component in the management of valuation adjustments, reflecting the funding cost of uncollateralized derivatives. LVA represents the additional cost incurred when a bank enters into uncollateralized derivative transactions that require funding, incorporating the liquidity premium associated with obtaining funding for these positions. LVA hedging aims to mitigate the financial impact of funding costs associated with uncollateralized exposures. The CVA is calculated considering the potential exposure to each counterparty in future periods. The Debit Valuation Adjustment (DVA) is a valuation adjustment similar to CVA, but generated by the Bank's credit risk assumed by our counterparties. In the case of derivative instruments contracted with Central Clearing Houses, where the variation margin is contractually defined as a firm and irrevocable payment, this payment is considered part of the derivative's fair value. The Liquidity Valuation Adjustment (LVA) has become a key component in the management of valuation adjustments, reflecting the funding cost of uncollateralized derivatives. LVA represents the additional cost incurred when a bank enters into uncollateralized derivative transactions that require funding, incorporating the liquidity premium associated with obtaining funding for these positions. LVA hedging aims to mitigate the financial impact of funding costs associated with uncollateralized exposures. For loans and advances covered by fair value hedging transactions, changes in their fair value related to the risk or risks covered in these hedging transactions are recorded. Equity instruments and contracts related to these instruments must be measured at fair value. Nevertheless, in certain circumstances, the Bank may use cost as an appropriate fair value estimate. This may be necessary, for example, if the recently available information is insufficient to measure the fair value or if a wide range of possible fair value measures exists, and the cost represents the best fair value estimate within that range. Furthermore, the Bank may irrevocably elect to present subsequent changes in the instrument's fair value in other comprehensive income. As of June 30, 2026, and 2025, and December 31, 2025, no significant investments in listed financial instruments had ceased to be recorded at their quoted market value due to their market being unable to be considered active.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued The amounts at which financial assets/liabilities are recorded represent, in all material respects, the Bank's maximum exposure to credit risk at each reporting date. The Bank also has collateral and other credit enhancements to mitigate its exposure to credit risk, consisting mainly of mortgages, cash, equity and personal guarantees, leased and rented assets, assets purchased under repurchase agreements, securities lending and credit derivatives. Valuation techniques According to IFRS 13 'Fair Value Measurement', a fair value hierarchy is established based on three levels: Level 1, Level 2 and Level 3, in which the highest priority is given to quoted prices (unadjusted) in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. Financial instruments at fair value and determined by published prices in active markets (Level 1) comprise government bonds, corporate bonds, exchange-traded derivatives, securitized assets, equities, short positions and issued bonds. In cases where quotations cannot be observed, management best estimates what the market would price using its own internal models. In most cases, these internal models use data based on observable market parameters as significant inputs (level 2) and sometimes use significant unobservable inputs in market data (level 3). Various techniques are used to estimate it, including extrapolating observable market data. The most reliable evidence of the fair value of a financial instrument on initial recognition is the transaction price unless the value of that instrument can be derived from other market transactions by the same or a similar instrument or valued using a valuation technique in which the inputs used include only observable market data, mainly interest rates. The main techniques used as of June 30, 2026, and 2025, and December 31, 2025 by the Bank's internal models to determine the fair value of financial instruments are described below: i. The present value method is used to value financial instruments that allow static hedging (mainly forwards and swaps). Expected future cash flows are discounted using the interest rate curves of the corresponding currencies. As a rule, interest rate curves are data that can be observed on the markets. ii. In the valuation of financial instruments that require dynamic hedging (mainly structured options and other structured instruments), the “Black-Scholes” model is normally used. Where appropriate, observable market inputs are used to obtain factors such as the diluted bid-offer, exchange rates, volatility, correlation between indices and market liquidity. iii. In the valuation of certain financial instruments subject to interest rate risk, such as interest rate futures, caps and floors, the present value method (futures) and the “Black-Scholes” model (“plain vanilla” options) are used. The main inputs used in these models are mainly observable market data, including the corresponding interest rate curves, volatilities, correlations and exchange rates. The fair value of the financial instruments calculated by the aforementioned internal models considers contractual terms and observable market data, including interest rates, credit risk, exchange rates, the quoted market price of shares and market rates of raw materials, volatility, prepayments and liquidity. The Bank's management verifies that the valuation models do not incorporate significant subjectivity. Therefore, if necessary, these methodologies can be adjusted and calibrated through internal calculations of fair value and subsequent comparison with the corresponding actively traded prices. The Bank has developed a formal process for the systematic valuation and management of financial instruments, implemented in all units included in the scope of consolidation. The governance structure of this process distributes responsibilities between two separate divisions: Treasury (responsible for the development, marketing and daily management of financial products and market data) and Market Risks (responsible for the periodic validation of valuation models and market data, the process of calculating risk metrics, standards for approving new transactions, market risk management and the implementation of valuation adjustment standards). Approving a new product involves several steps (application, development, validation, integration into corporate systems and quality review) before production. This process ensures the rating systems are properly reviewed and stable before use. Details of the most significant derivative products and families, together with their respective valuation techniques and inputs, by type of asset, are set out in Note 44 'Fair value of financial assets and liabilities' in these Interim Consolidated Financial Statements.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued 11. Fixed assets This category includes the buildings, land, furniture, vehicles, computer hardware and other fixed assets owned by the consolidated entities. Assets are classified according to their use as follows: a. Fixed assets for own use Fixed assets for own use (which includes, among others, tangible assets received by consolidated entities in settlement, in whole or in part, of financial assets representing receivables from third parties, and which are expected to be used on a continuing basis in the entity’s own operations) are presented at acquisition cost, less the corresponding accumulated depreciation and, where applicable, impairment losses resulting from comparing the net carrying amount of each item with its corresponding recoverable amount. Depreciation is calculated using the straight-line method over the acquisition cost of assets minus their residual value, assuming that the land on which buildings and other structures stand has an indefinite life and is not subject to depreciation. The Bank applies the following useful lives for the tangible assets that comprise its assets: ITEM Useful Life (Months) Land - Paintings and works of art - Carpets and curtains 36 Computers and Hardware 36 Vehicles 36 Machines and general equipment 60 Office furniture 60 Telephone and communication systems 60 Security systems 60 Rights over telephone lines 64 Air conditioning systems 84 ATMs and teleconsultations 120 Other installations 120 Buildings 1,200 At each reporting period, the consolidated entities assess whether there is any indicator that the carrying amount of any tangible asset exceeds its recoverable amount. If this is the case, the asset's carrying amount is reduced to its recoverable amount. Future depreciation charges are adjusted under the revised carrying amount and to the new remaining useful life, if an adjustment of the latter is necessary. Likewise, the estimated useful lives of the items of property, plant and equipment held for own use are reviewed at the end of each reporting period to detect significant changes. If changes are detected, the useful lives of the assets are adjusted by correcting the depreciation charge to be recorded in the Interim Consolidated Statements of Income in future years based on the new useful lives. Maintenance expenses relating to tangible assets held for own use are recorded as an expense in the period in which they are incurred. b. Assets leased out under operating leases The criteria used to record the acquisition cost of assets leased out under operating leases, calculate their depreciation and their respective estimated useful lives, and record their impairment loss are the same criteria as those for fixed assets held for own use.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued 12. Leases At the contract's creation, the Bank assesses whether it contains a lease or not. A contract contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for compensation. To assess whether a contract conveys the right to control the use of an identified asset, the Bank assesses whether: • The contract involves using an identified asset. This may be specified explicitly or implicitly and should be physically identified. The asset is not identified if the supplier has a significant substitution right. • The Bank has the right to obtain all the economic benefits from using the asset throughout the contract's duration. • The Bank has the right to direct the use of the asset – this is the decision-making purpose for which the asset is used. i. As a lessee The Bank recognizes a right-of-use asset and a lease liability at the starting date of the lease according to the IFRS 16 'Leases'. The Bank's main contracts are for offices and branches which are necessary to undertake its activities. In the beginning, the right-of-use asset is equal to the lease liability. It is calculated as the present value of the lease payments, which are discounted using the Bank's incremental interest rate at the starting date and considering each contract's duration. The average incremental interest rate is 2.12%. Subsequently, the asset is straight-line depreciated according to the contract's duration, and the financial liability is amortized in terms of the monthly payments. The financial interest is charged to net interest income, and the depreciation is charged to the depreciation expense of each financial year. The lease's term encompasses non-cancellable periods stipulated within each contract. In the case of a lease contract with indefinite duration, the Bank has determined to assign a span equal to the longest of the non-cancellable period of its lease contracts. Contracts with a non-cancellable period of 12 months or less are treated as short-term leases. Therefore, the related payments are recorded as a straight-line expense. Any change in the lease term or rent is treated as a new measurement of the lease. In the initial measurement, the Bank measures the right-of-use of the asset at cost. The rent of the lease contracts is agreed in UF and payable in Chilean pesos. According to Circular No 3,649 of the FMC, the monthly UF variation that affects all contracts established in such monetary units should be treated as a new measurement. Therefore, readjustments should be recognized as an amendment to the obligation, and in parallel, the amount of the related asset should be adjusted. The Bank has not entered into lease agreements with guarantee clauses for residual value or variable lease payments. ii. As a lessor When the Bank acts as a lessor, it first determines if it corresponds to a financial or operating lease. To do this, the Bank evaluates whether it has substantially transferred all the risks and benefits of the asset. If so, this corresponds to a financial lease. Otherwise, it is an operating lease. The Bank recognizes lease rentals received on a straight-line income basis over the lease term. iii. Third-party financing The sum of present values of the lease payments receivable from the lessee is recognized in the line item: 'Loans and receivables from customers' in the Interim Consolidated Statements of Financial Position. This includes the price of the lessee's right-to-call option at the end of the lease term when there is reasonably certain that the lessee will exercise said right. The financial income and expense derived from these contracts are recorded in the Interim Consolidated Statements of Income under 'Interest income' and 'Interest expense', respectively, to achieve a constant return rate over the lease term. 13. Factoring transactions Factored receivables are valued at the amount disbursed by the Bank in exchange for invoices or other commercial instruments representing the credit the transferor assigns to the Bank. The price difference between the amounts disbursed and the actual face value of the loans is recorded as interest income in the Interim Consolidated Statements of Income using the effective interest method over the financing period. When the assignment of these instruments involves no liability on the part of the assignee, the Bank assumes the risks of insolvency of the parties responsible for payment.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued 14. Intangible assets Intangible assets are non-monetary assets (identifiable separately from other assets) without physical substance arising from legal or contractual rights. The Bank recognizes an intangible asset, whether purchased or self-created (at cost) when the asset's cost can be measured reliably. Additionally, the future economic benefits attributable to the asset are expected to flow into the Bank. To calculate intangible assets, they are recorded initially at their acquisition or production cost, from which the accumulated amortization and accumulated impairment loss are subtracted. Internally developed computer software is recorded as an intangible asset if, among other requirements (primarily the Bank's ability to use or sell it), it can be identified and its ability to generate future economic benefits can be demonstrated. Intangible assets are amortized linearly based on their estimated useful life, defined by default at 36 months. They can be modified if the extent to which the Bank will benefit from its use for a different period than the mentioned above is demonstrated. Expenditure on research activities is recorded as an expense incurred in the year and cannot be subsequently capitalized. 15. Non-current assets held for sale Non-current assets held for sale and discontinued operations Per the IFRS 5, 'Non-current assets held for sale and discontinued operations', a non-current asset is classified as held for sale if their carrying amount will be recovered mainly through a sale transaction rather than through continued use. To apply the above classification, the asset must meet the following requirements: • It must be available in its current conditions for immediate sale, and a sale must be highly probable. • For it to be highly probable, the appropriate management level must be engaged in a plan to sell the asset (or group of assets for its disposal). Also, a program to find a buyer and completing said purchase must have been actively initiated. • Furthermore, the sale should be expected to qualify for recognition as a completed sale within one year of the classification date. Assets classified in this way will be measured at the lower of their carrying amount or their fair value less costs to sell. As of June 30, 2026, the Bank has fixed assets that meet the definition of non-current assets held for sale, which amount to approximately Ch$28,865 million. Assets received in payment or awarded through judicial foreclosure proceedings. The goods received or awarded in lieu of payment of loans and accounts receivable from clients are recorded, in the case of assets awarded in lieu of payment, at the price agreed between the parties or, conversely, in those cases where there is no agreement between them, by the amount for which the Bank acquired said assets in a judicial auction. In both cases, an independent assessment of the market value of the goods is determined based on the state in which they are acquired. If the value of loans and receivables exceeds the fair value of the asset received or foreclosed as payment minus selling cost, the difference is recorded in the Interim Consolidated Statements of Income under 'Credit loss expenses'. These assets are subsequently valued at the lower amount between the initially recorded figure and the net realizable value, which corresponds to their fair value (liquidation value determined through an independent appraisal) minus their respective costs of sale. The differences between the two are recognized in the Interim Consolidated Statements of Income under 'Other operating expenses'. At the end of each year, the Bank reviews the selling cost of assets received or foreclosed in payment, which is then applied from that date onwards and into the following year. In December 2025, the average cost was estimated at 7.15% of the appraised value (7.11% as of December 31, 2025). In addition, a review of the appraisals by an independent is carried out every 18 months to adjust the fair value of the assets.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued In general, it is estimated that these assets will be disposed of within one year from the date they are acquired. In compliance with the provisions of Article 84 of the General Banking Law, those assets that are not sold within such period are written off in a single installment, and an extension is requested from the FMC. Also included are assets recovered from finance lease transactions, as lessor, that are held for sale rather than being re-leased through new finance lease transactions. 16. Income and expense recognition The most important criteria used by the Bank to recognize its revenues and expenses are summarized as follows: a. Interest revenue, interest expense, and similar items Interest income, interest expense and similar items are recognized on an accrual basis using the effective interest rate method. Nevertheless, the Bank ceases to recognize income on an accrual basis when a loan or one of its installments is 90 days overdue. This means that interest, adjustments or commissions are not recognized in the Interim Consolidated Statements of Income unless effectively received. These interest and readjustments are generally referred to as 'suspended' and are recorded in memorandum accounts, which do not form part of the Interim Consolidated Statements of Financial Position but are reported as part of the supplementary information therein (Note 30 and 31). Interest incomes of previous 'transactions with suspended accrual' are only recognized again when the debtor is up to date with its obligations. b. Commissions, fees and similar items Fee and commission income and expenses are recognized in the Interim Consolidated Statements of Income using the criteria set out in IFRS 15, ‘Revenue from contracts with customers’. Under IFRS 15, 'Revenue from contracts with customers', the Bank recognizes revenue when it satisfies its performance obligations by transferring the service (an asset) to the customer. Under this definition, an asset is transferred when the customer obtains control over the asset. The Bank considers the contractual terms and its traditional business practices for determining the transfer price. The transfer price is the amount of compensation the entity expects to be entitled in order to transfer committed goods and services to the customer, excluding amounts collected on behalf of third parties. The Bank consistently applies the recognition method for each performance obligation, whether it is satisfied over time or at a specific point in time. The main income arising from commissions, fees, and similar items are: • Credit prepayment fees, which include fees related to customer prepayments of credit operations. • Fees and commissions on loans with letters of credit, which comprise fees and commissions related to granting loans with letters of credit. • Fees for lines of credit and overdraft fees, which refer to fees accrued during the year to grant credit lines and current account overdrafts. • Fees for guarantees and letters of credit, which include fees accrued during the year to grant payment guarantees for real or contingent third-party obligations. • Card service fees. These refer to fees earned and accrued for the year related to the usage of credit, debit and other cards. • Account administration fees. These comprise fees incurred for maintenance of current, savings and other accounts. • Fees and commissions for collections and payments, which include fees and commission income generated by the Bank's collections and payment services. • Commissions for brokerage and administering securities, which refer to income from commissions generated on brokerage, issuances, administration, and custody of securities.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued • Remuneration for the administration of mutual funds, investment funds or others, which comprises commissions from fund management companies separated by type of client (natural or legal person). • Insurance intermediation and consultancy fees, which include income generated through insurance sales, separated by the type of insurance brokered. • Fees for financial leasing transaction services, which refer to those financial leasing services in which the Bank acts as a lessor. • Securitization fees, which include fees for securitization services. • Fees for financial advisory services, which comprise those involved in advisory services concerning the issuance and placement of financial instruments, restructuring and funding financial liabilities, sale and purchase of companies, and others. • Other commissions earned, which include income generated by currency exchanges, issuing cashier checks and guarantee slips, trust commissions, foreign trade operations, student loan administration, and other services. Commission expenses comprise: • Card transaction fees, which involve commissions generated by credit cards, debit cards and the provision of funds related to the income generated from card service fees. • License fees of card brands. These are fees paid to the main card brands: credit, debit and provision of funds. • Other fees for services linked to the credit card system and cards with the provision of funds. • Expenses for loyalty and merit program obligations for card clients. They refer to expenses related to customer benefit programs related to the use of cards. • Fees for securities transactions. They comprise fees for deposit, safekeeping and brokerage of securities, investments in mutual funds, stock exchanges, central counterparty and market infrastructure services. • Other fees for services received. They include securities services, foreign trade, correspondent banking, ATMs and wire transfer fees. • Fees for clearing high-value payments, which include fees to ComBanc, CCLV, etc. The relationship between the Segment Note and the disaggregated income is presented in Note 32 Commission Income and Expenses. The Bank maintains loyalty plans associated with its credit cards, which under IFRS 15 “Revenue from ordinary activities from contracts with customers” have the necessary provisions to meet the delivery of the committed future performance obligations, or said obligations are settled immediately when they are generated. c. Non-financial income and expenses These are recognized under the criteria established in IFRS 15, 'Revenue from contracts with customers', identifying the performance obligation and when they are satisfied (accrued). d. Commissions in the origination of loans Financial fees and commissions arising from the origination of loans, mainly origination or research and information gathering fees are accrued and recognized in the Interim Consolidated Statements of Income over the life of the loan. 17. Provisions for credit risk on loans and receivables and contingent liabilities The Bank continuously evaluates the entire portfolio of loans and contingent loans, as established by the FMC, to promptly create sufficient provisions to cover the expected loss linked with the debtors' characteristics and their loans based on payment and subsequent recovery. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 28
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued The Bank uses the following models established by the FMC and approved by the Board of Directors to assess its loan and contingent loan portfolio: • Individual assessment of debtors – This applies to debtors recognized as individually significant, that is, with substantial levels of debt, and to those who, even if not significant, are not able to be classified in a group of financial assets with similar credit risk characteristics, and which, due to their size, complexity or level of exposure, require detailed analysis • Group assessment of debtors - Group assessments are relevant for residential mortgage and consumer credit exposures, in addition to commercial student credit exposures and exposures to debtors that simultaneously meet the following conditions: i. The Bank has an aggregate exposure to the same counterparty of less than UF 20,000. The aggregate exposure is considered as the gross amount before provisions or other mitigation factors. It also includes residential mortgages in the calculation. Concerning off-balance sheet items (contingent loans), the gross amount is calculated by applying the credit translation factors defined in Chapter B-3 of the CASB. ii. Each aggregate exposure to a single counterparty does not exceed 0.2% of the total portfolio of loans assesses on a group basis. Group assessments are suitable for dealing with many transactions, each of a low amount, involving individuals or small companies. The Bank groups debtors with similar credit risk characteristics by associating each group with a certain probability of non- performing and a recovery rate based on a substantiated historical analysis. To this end, the Bank implemented the standard model for mortgage and commercial loans and its internal model for consumer loans. A. Provisions for individual assessments The individual assessment of a commercial loan debtors is necessary, as established by the FMC, in the case of companies that require detailed knowledge and analysis due to their size, complexity, or level of exposure to the entity. The analysis of debtors focuses firstly on their credit quality. Then, it classifies them in the risk category corresponding to the debtor and their respective credit operations and contingent loans after assigning them to one of the three portfolio statuses: Normal, Substandard or Impaired. The risk factors used in this analysis are the industry or sector, business situation, partners and management, the company's financial situation and ability to pay, and payment behavior. The portfolio categories and their definitions are as follows: 1. Normal Portfolio includes debtors in which their payment capacity will permit them to pay their obligations and commitments. Evaluations of the current economic and financial environment do not indicate that this will change. The classifications assigned to this portfolio are categories from A1 to A6. 2. Substandard Portfolio includes debtors with financial difficulties or significant deterioration of their payment ability. There is reasonable doubt concerning the future reimbursement of the capital and interest within the contractual terms, with limited ability to meet short-term financial obligations. The classifications assigned to this portfolio are categories B1 to B4. 3. Impaired Portfolio includes debtors and their credits for which repayment is considered remote, as they show a deteriorated or no payment capacity. This portfolio includes debtors who have stopped paying their debts or with obvious indications that they will stop paying, as well as those that require a forced restructuring of debts, reducing the obligation or postponing the term of the principal or interest, and any debtor who is in arrears equal to or greater than 90 days in the payment of interest or capital. The classifications assigned to this portfolio are categories C1 to C6. Normal and Substandard Portfolio As part of the individual assessment of debtors, the Bank classifies them into the following categories, assigning them a probability of default and severity, which result in the expected loss percentages: Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 29
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued Portfolio Debtor's Category Probability of Non- performance (%) Severity (%) Expected Loss (%) Normal Portfolio A1 0.04 90.00 0.0360 A2 0.10 82.50 0.0825 A3 0.25 87.50 0.2188 A4 2.00 87.50 1.7500 A5 4.75 90.00 4.2750 A6 10.00 90.00 9.0000 Substandard Portfolio B1 15.00 92.50 13.8750 B2 22.00 92.50 20.3500 B3 33.00 97.50 32.1750 B4 45.00 97.50 43.8750 The first step to determine the amount of provisions is to assess the affected exposure, which comprises the book value of loans plus contingent loans, minus the amounts that are feasible to recover through the execution of financial collateral or other collateral covering the operations. To this exposure, the respective loss percentages are applied. In the case of collateral, the Bank must demonstrate that the value assigned to the deduction reasonably reflects the value that can be realized from the disposal of the assets or equity instruments. If the debtor's credit risk is substituted for the guarantor's credit quality, this methodology will only apply if the guarantor or surety is an entity qualified in a category similar to investment grade by a local or international rating agency recognized by the FMC. Under no circumstances may an endorsed valuable be deducted from the exposure amount, a procedure applicable only in the case of financial guarantees or real collateral. Notwithstanding the above, the Bank must maintain a minimum provision of 0.5% over loans and contingent loans in the normal portfolio. Impaired Portfolio The impaired portfolio includes all loans and the entire value of contingent loans of the debtors overdue by 90 days or more on a single payment of interest or principal of any loan at the end of the month. It also includes debtors who have been granted a loan to refinance loans overdue by 60 days or more and debtors who have undergone forced restructuring or partial debt forgiveness. The impaired portfolio excludes: a) residential mortgage loans, with payments overdue less than 90 days; and b) loans to finance higher education granted according to Law No 20,027, that do not fulfil the non-performing conditions outlined in Circular No 3,454 of December 10, 2008. The provision for an impaired portfolio is calculated by determining the expected loss rate for the exposure, deducting the value of recoverable collateral and deducting the present value of recoveries made through collection services after the related expenses. Once the expected loss range is determined, the related allowance rate is applied over the exposure amount, including loans and contingent loans related to the debtor. The allowance rates applied over the calculated exposure are as follows: Classification Estimated range of loss Allowance C1 Up to 3% 2% C2 Between 3% and 20% 10% C3 Between 20% and 30% 25% C4 Between 30% and 50% 40% C5 Between 50% and 80% 65% C6 More than 80% 90% Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 30
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued All the debtor's loans are maintained in the Impaired Portfolio until its payment ability is normalized, notwithstanding the charge-off of each loan that meets Title II of Chapter B-2 of the CASB. Once the circumstances that led to classification in the Impaired Portfolio have been overcome, the debtor can be removed from this portfolio once all the following conditions are met: i. The debtor has no obligations overdue with the Bank for 30 consecutive days or more. ii. The debtor has not been granted loans to refinance its obligations. iii. At least one of the payments includes the amortization of capital. iv. Two payments must already be made if the debtor has made partial loan payments in the last six months. v. If the debtor must make monthly payments, four consecutive installments must have been paid. vi. The debtor does not appear to have bad debts in the information provided by the FMC, except for insignificant amounts. B. Provisions for group assessments Group assessments are relevant for residential mortgage and consumer credit exposures, in addition to commercial student loan exposures and debtor exposures that simultaneously meet the following conditions: i. The Bank has an aggregate exposure (the exposure on the same Business Group at a consolidated level) to the same counterparty of less than UF 20,000. The aggregate exposure is considered gross of provisions or other mitigating factors and includes residential mortgage loans for its calculation. Concerning off-balance sheet items, the gross amount is calculated by applying the credit translation factors defined in Chapter B-3 of the CASB. ii. Each aggregate exposure to a single counterparty does not exceed 0.2% of the total portfolio evaluated under group assessment. To determine provisions, group assessments require the creation of groups of loans with homogeneous qualities in terms of the type of debtors and contracted loan terms in order to establish, using technically sound estimates and prudential criteria, the payment behavior of the group and the recoveries of its non-performing loans. This is done using a model based on the characteristics of the debtors, payment history, outstanding loans and delinquency, among other relevant factors. The Bank uses methodologies to determine credit risk based on internal and/or standard models to estimate provisions for the group- assessed portfolio. These include commercial loans for debtors who are not individually assessed, residential mortgage loans and consumer loans (including installment loans, credit cards and overdraft facilities). This methodology helps to independently identify the portfolio's performance one year ahead and determines the provision necessary to cover the losses arising in the period of one year from the balance sheet date. Clients are segmented according to their internal and external characteristics into groups or profiles to differentiate the risk of each portfolio in a more appropriate and orderly manner (client-portfolio model). This is known as the profile assignment method. The profile assignment method is based on a statistical construction method, constituting a relationship through a logistic regression between variables such as non-performance, external credit behavior, sociodemographic variables, and a response variable that determines a customer's risk, which in this case is non-performance equal to or greater than 90 days. Hence, common profiles are established and assigned a Probability of Non-Performance (PNP), also known as a Probability of Default (PD), and a recovery rate based on a substantiated historical analysis known as Loss Given Default (LGD). Therefore, once the client has been assigned a profile and a PNP and a LGD has been set for their type of loan, the exposure at default (EXP) is calculated. This exposure includes the book value of the loans and receivables from the customer, plus contingent loans, minus any amount that can be recovered by activating collateral (for loans other than consumer loans). Notwithstanding the above, in establishing provisions related to mortgage and commercial loans, the Bank must recognize minimum provisions according to standard methods established by the FMC for those types of loans. While this is considered a conservative minimum base, it does not relieve the Bank of its responsibility to have its own internal methodologies for determining adequate provisions to cover the portfolio's credit risk. Provisions must be made considering the higher value obtained between the respective standardized method and the internal method.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued Standard method of provisions for group assessments 1. Residential mortgage portfolio Under the CASB, the Bank applies the standard provisioning method for residential mortgages. Under this method, the expected loss factor applicable to the number of residential mortgage loans will depend on the delinquency of each loan and the ratio, at the end of each month, between the outstanding principal amount of each loan and the value of the mortgage collateral (loan-to-value or LTV) that covers it. The relevant provisioning factor according to delinquency and LTV is as follows: LTV Range Days past due at month-end 0 1-29 30-59 60-89 Impaired portfolio LTV ≤ 40% PNP(%) 1.0916 21.3407 46.0536 75.1614 100 LGD (%) 0.0225 0.0441 0.0482 0.0482 0.0537 EL (%) 0.0002 0.0094 0.0222 0.0362 0.0537 40% < LTV ≤ 80% PNP(%) 1.9158 27.4332 52.0824 78.9511 100 LGD (%) 2.1955 2.8233 2.9192 2.9192 3.0413 EL (%) 0.0421 0.7745 1.5204 2.3047 3.0413 80% < LTV ≤ 90% PNP(%) 2.515 27.93 52.58 79.6952 100 LGD (%) 21.5527 21.66 21.92 22.1331 22.231 EL (%) 0.5421 6.0496 11.5255 17.639 22.231 LTV > 90% PNP(%) 2.74 28.43 53.08 80.3677 100 LGD (%) 27.2 29.03 29.59 30.1558 30.2436 EL (%) 0.7453 8.2532 15.7064 24.2355 30.2436 LTV= (Loan-to-Value Ratio) unpaid loan principal/value of the mortgage collateral. EL = Expected loss This standardized approach will also be applied to residential leasing transactions, following the same criteria described above and considering the leased asset value equivalent to the amount of the mortgage collateral. If the same debtor holds more than one residential mortgage loan with the Bank and one is overdue by 90 days or more, all these loans will be assigned to the impaired portfolio, with provisions calculated for each according to their respective LTV percentages. In the case of residential mortgage loans linked to housing and subsidy programs of the State of Chile, provided that they are contractually covered by the auction insurance supplied by the latter, the provisioning percentage may be weighted by a loss mitigation (LM) factor, which depends on the LTV percentage and the value of the house in the deed of sale (V). Therefore, the LM factors to be applied to the corresponding provisioning percentage are presented in the table below: Loss mitigation (LM) factor for loans with state auction insurance LTV Range Segment V: Deeded house price (UF) V<1,000 1,000< V <= 2,000 LTV <= 40% 100 40% < LTV <= 80% 80% < LTV <=90% 95 96 LTV > 90% 84 89 2. Commercial loan portfolio Following the CASB, the Bank applies the standard model of provisions for commercial loans in the group portfolio, depending on whether it corresponds to commercial leasing, student or other commercial loans. Before implementing the standard method, the Bank used internal models to determine provisions for commercial loans assessed on a group basis.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued i. Commercial leasing operations For these operations the provision factor must be applied to the current value of commercial leasing operations (including the purchasing option at the end of the lease). Therefore, it will depend on the delinquency of each operation, the type of leased asset and the relationship, at the closing of each month, between the current value of each operation and the value of the leased asset (LTV), as indicated in the following tables: Probability of Non-Performance (PNP) applicable according to delinquency and type of asset (%) Days past due at the end of the month Type of asset Real estate Non-real estate 0 0.79 1.61 1-29 7.94 12.02 30-59 28.76 40.88 60-89 58.76 69.38 Non-performing portfolio 100 100 Loss Given Default (LGD) applicable by LTV range and type of asset (%) LTV range (*) Real estate Non-real estate LTV ≤ 40% 0.05 18.2 40% < LTV ≤ 50% 0.05 57 50% < LTV ≤ 80% 5.1 68.4 80% < LTV ≤ 90% 23.2 75.1 LTV > 90% 36.2 78.9 (*) LTV= Current value of operation/leased asset value The LTV ratio will be determined considering the appraisal value, expressed in UF for real estate and pesos for non-real estate, recorded at the time of granting the respective loan, considering any situations that may be causing temporary rises in the asset price at that time. ii. Student loans For these operations, the provision factor should be applied to the student loan and the exposure of the contingent loans, when applicable. The determination of this factor depends on the type of student loan and the enforceability of the payment of capital or interest at the end of each month. When payment is due, the factor will also depend on the delinquency of the loan. For the loan classification, a distinction is made between those granted for financing higher studies under Law No 20,027 (CAE) and, on the other hand, the CORFO guaranteed loans or other student loans.

Other commercial loans and factoring For factoring transactions and other commercial loans, the provisioning factor, applicable to the amount of the loan and the contingent loan exposure, will depend on the delinquency of each transaction and the ratio at the end of each month between the debtor's obligations to the Bank and the value of the collateral (LTVC) securing them, as indicated in the following tables: Probability of Non-Performance (PNP) applicable according to delinquency and LTVC range (%) Days past due at month-end Guarantee No collateral LTVC ≤ 100% LTVC > 100% 0 1.86 2.68 4.91 1-29 11.6 13.45 22.93 30-59 25.33 26.92 45.3 60-89 41.31 41.31 61.63 Non-performing portfolio 100 100 100 Loss Given Default (LGD) applicable according to LTVC range (%) Collateral (with/without) LTVC Range Factoring and other commercial loans without responsibility of assignor Factoring with responsibility of assignor Collateral LTVC ≤ 60% 5 3.2 60% < LTVC ≤ 75% 20.3 12.8 75% < LTVC ≤ 90% 32.2 20.3 90% < LTVC 43 27.1 No collateral 56.9 35.9 The collateral used to calculate the LTVC ratio of this method may be of a specific or general nature or those that are simultaneously specific and general in nature. However, a collateral can only be considered if, according to the respective coverage clauses, it was set in the first degree of preference in favor of the Bank and it only guarantees the debtor's credits concerning which it is attributed (not shared with other debtors). The invoices assigned in the factoring operations, or the guarantees linked to mortgage loans, regardless of their coverage clauses, will not be considered in the calculation. The following considerations must be taken into account when calculating the LTVC ratio: i. Transactions with specific guarantees: those in which the debtor provided specific guarantees for generic commercial loans and factoring. The LTVC ratio is calculated separately for each secured transaction as the division between the loan amount and the contingent loan exposure over the collateral's value. ii. Transactions with general guarantees: when the debtor is granted general or general and specific guarantees, the Bank calculates the corresponding LTVC jointly for all generic commercial loans, factoring and operations not contemplated in the above paragraph i), as the division between the sum of the amounts of loans and contingent loan exposures over the general or specific guarantees that, according to the scope of the remaining coverage clauses, protect the loans considered in the numerator of the ratio mentioned above.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued The amounts of collateral used in the LTVC ratio in (i) and (ii) should be determined according to the: • The collateral’s last valuation, whether in its appraisal or fair value, depending on the type of collateral in question. The criteria in Chapters 7-12 of the Updated Collection of Banking Regulations (from now on: UCBR) should be considered to determine fair value. • Possible situations that could be causing temporary rises in the values of the collaterals. • Limits to the amount of coverage established in their respective clauses. 3. Consumer loan portfolio Expected Loss (EL), which corresponds to the product of Probability of Default (PD) and Loss Given Default (LGD), will be uniformly applied to all consumer loans and contingent loans that the borrower holds with the bank and its subsidiaries in Chile, including consumer leasing operations. In the case of contingent operations, the exposure measure must be calculated in accordance with the provisions set forth in Chapter B-3 of the CASB issued by the FMC, the latest update which was published on March 6, 2024 (Circular No. 2,346). To define the value of the PNP, the following factors must be calculated for each borrower: • Delinquency level at the bank: this corresponds to the maximum delinquency level (in days) in the consumer portfolio, including consumer leasing operations, that the borrower has with the bank at the end of the month for which provisions are being determined. For clients with more than one operation, the highest value among them will be used. This variable must be measured across all entities that make up the institution’s global consolidated level. • 30-day delinquency in the financial system: this indicates whether the borrower has at least one direct debt with delinquency equal to or greater than 30 days in any of the 3 months prior to the provisioning month. To construct this variable, the borrower's delinquency across all known credit providers should be considered, using the debtor list compiled by the FMC, as well as the Bank’s own global consolidated data and various financial products. Only debts with communication restrictions under Law No. 19,628 on the Protection of Private Life should be excluded. • Ownership of a mortgage loan: this variable identifies whether the borrower has a current residential mortgage loan in the financial system. For this, the Bank must use the most recent available information at the time provisions are calculated, considering the debtor list compiled by the FMC, in addition to the Bank’s own global consolidated data. Based on the above variables, the PNP is determined according to the following table: With a residential mortgage loan in the system Without a residential mortgage loan in the system Maximum level of delinquency in the month and bank (interval in days that includes extremes) No over due loans of more than 30 days in the system With over due loans of more than 30 days in the system No over due loans of more than 30 days in the system With over due loans of more than 30 days in the system 0 and 7 3.3% 14.6% 6.6% 19.8% 8 and 30 20.4% 41.6% 30.6% 48.5% 31 and 60 50.2% 63.0% 65.1% 66.3% 61 and 89 62.6% 81.7% 72.3% 86.9% If the borrower is in default (>90 days), the assigned PNP will be 100%. To determine the value of the LGD, it must be identified whether the borrower has a residential mortgage loan in the system (as defined for PNP), and the type of loan involved. The LGD to be used is defined in the table below: Leasing operations and auto loans Installments loans Credit card, overdraft and other consumer loans With residential mortgage loan in the system 33.2% 47.7% 49.5% Without residential mortgage loan in the system 33.2% 56.6% 60.3% Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 35
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued The assignment of the LGD value should follow these guidelines: • "Leasing operations and auto loans" include loans whose purpose is to finance the acquisition of personal-use vehicles, which are pledged as collateral in favor of the institution. This category also includes financial consumer leasing operations recorded under item 148000400 of the CASB of the FMC. • "Installment Loans" correspond to those recorded under item 148000100 of Chapter C-3 of the CASB (Consumer loans in installments), provided they were granted following the signing of a promissory note that clearly states the principal amount, term, interest rate, and number of installments, without a predefined use of the funds (unrestricted use by the borrower), and do not fall into the previous category. • If a loan does not fall under either of the two definitions above but is classified under line 148000000 (Consumer loans) of the CASB, the LGD value assigned to the “Credit cards, credit lines, and other consumer loans” category should be applied. C. Provisions for contingent loans Contingent loans are transactions or commitments in which the Bank assumes a credit risk by obliging itself vis-à-vis third parties upon a future event to make a payment or a disbursement to be recovered from its clients. To calculate the provisions as indicated in Chapter B-1 of the CASB, the amount of exposure to be considered shall be equal to the percentage of the contingent claim amounts indicated below: Type of loan Credit Translation Factors (CTF) Immediately repayable unrestricted credit lines 10% Contingent loans linked to student loan (CAE) 15% Letters of credit for goods movement operations 20% Other unrestricted credit lines 40% Debt purchase commitments in local currencies abroad 50% Transactions related to contingent events 50% Guarantees and sureties 100% Other credit commitments 100% Other contingent loans 100% In the case of transactions with clients with non-performing loans, such exposure shall always equal 100% of their contingent loans. D. Collateral and credit enhancements Collateral is only considered in calculating provisions when they are legally established and when the conditions allowing their eventual activation or settlement in the Bank's favor are met. Collateral valuation (mortgages or pledges) reflects the net cash flow obtained from selling goods or equity instruments, or from capital minus estimated expenses in the event of a debtor's non- performance. For mortgages and pledges on goods, the Bank undertakes analyses that reflect the relationship between the prices obtained in an eventual settlement and their appraisal or foreclosure values. Nevertheless, the valuations of mortgages and other goods received are based on valuations carried out by independent professionals, while maintenance and transaction costs are based on historical data from at least 3 years prior. The Bank has the necessary collateral revaluation standards in place. Financial collateral, measured through fair value adjustments, may only be deducted from credit risk exposures when they are provided to secure the performance of the credits concerned. The adjusted fair value is obtained by applying the interest rate and currency volatility discount factors established by the FMC and subtracting settlement costs. Determining provisions in the case of leased assets considers the value obtained on the disposal of the leased assets, considering the impairment that these may present, and the expenses related to their redemption and liquidation or eventual relocation. Determining provisions for factoring loans considers that the counterparty is the assignor of the documents endorsed to the Bank when the factoring is with liability and the debtor when the assignment is without liability of the assignor.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued E. Additional provisions According to FMC regulation, banks can establish provisions over the already described limits to protect themselves from the risk of non-predictable economic fluctuations that could affect the macroeconomic environment or a specific economic sector. As set out in number 9 of Chapter B-1 of the CASB of the FMC, these provisions shall be reported on the liability side in the same way as provisions on contingent claims. F. Provisions related to financing with FOGAPE guarantee Covid-19 The FMC requested that specific provisions be determined for loans secured by the FOGAPE Covid-19 guarantee, for which the expected loss must be determined. This is done by estimating the risk of each transaction, dismissing the guarantor's credit quality substitution, and following the appropriate individual or group analysis method per the clauses of the CASB Chapter B-1. This calculation must be made on an aggregate basis, grouping all transactions to which the same deductible percentage is applicable. Hence, the total expected loss resulting from the aggregate calculation of each transaction group must be compared with the total deductible corresponding to them. When the expected loss of the transactions of a group with the same deductible percentage is determined to be equal to or less than the aggregate deductible, the provisions are set without considering the FOGAPE Covid-19 guarantee, that is, without replacing the creditworthiness of the direct debtor for that of the guarantor. When they surpass the aggregate deductible, the provisions shall be determined using the substitution method set out in the CASB paragraph 4.1(a) of Chapter B-1 and shall be recognized in accounts separate from commercial, consumer and residential mortgage provisions. G. Provisions established for credit risk as a result of supplementary prudential requirements This corresponds to the provisions for credit risk required by the Committee’s prudential instructions in relation to credit risk management assessments under Chapters 1-13 of the UCBR and that do not qualify as provisions established per the definitions in Chapter B-1 of the CASB. H. Distressed loans and suspension of accrual Distressed loans, in the case of individual assessment, is made up of the loans classified in the Impaired Portfolio plus categories B3 and B4 of the Substandard Portfolio. In the case of group assessment, it includes the credits of the Impaired Portfolio. The Bank ceases to recognize income on an accrual basis in the Interim Consolidated Statements of Income when the loan or one of its installments is 90 days overdue. From the date interest is suspended until they are no longer impaired, loans shall not be credited with interest, adjustments or fees in the Interim Consolidated Statements of Financial Position. No income from such loans shall be recognized in the Interim Consolidated Statements of Income unless effectively received. I. Charge-offs As a general rule, charge-offs should be applied when the contractual rights to the cash flows expire. The charge-offs in question refer to the derecognition in the Interim Consolidated Statements of Financial Position of the assets corresponding to the respective transaction, including that part which may not be overdue in the case of a loan payable in installments or a leasing transaction (there are no partial charge-offs). This includes overdue, past-due and current installments, with the term corresponding to the time elapsed since the date on which payment of all or part of the obligation is in delinquency. Charge-offs are always booked against the credit risk provisions set up under Chapter B-1 of the CASB, regardless of the reason for the write-off. Charge-offs should be carried out in the following circumstances, whichever occurs first: 1. Based on all available information, the Bank concludes that it will not obtain flows from the loans recorded as an asset. 2. When an unencumbered claim is 90 days old since it was registered as an asset. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 37
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued 3. Upon expiration of the statute of limitations for actions to claim collection through an enforceable judgment or at the time of the rejection or abandonment of the enforcement of the title by an enforceable court decision. 4. When the period of arrears of a transaction reaches the time limit for charge-offs set out below: Type of loan Term Consumer loans with or without collateral 6 months Other transactions without collateral 24 months Commercial loans with collateral 36 months Mortgage loans 48 months Consumer leasing 6 months Other non-mortgage leasing transactions 12 months Mortgage leasing (household and business) 36 months J. Recovery of loans previously written off and receivables from clients Subsequent payments on written-off transactions shall be recognized in the profit or loss statement as recoveries of charged-off loans. When a recovery is perceived in the form of an asset received in lieu of payment, the income is recognized as the amount by which they are incorporated into the asset under the provisions of the Chapter of the CASB regarding Assets Received or Awarded in Lieu of Payment. The same approach is followed if the leased goods are recovered after a leased transaction is written off when such goods are incorporated as an asset. 18. Impairment of financial assets other than loans and receivables and contingent loans The Bank applies IFRS 9 'Financial Instruments' to determine the impairment of financial assets measured at fair value through other comprehensive income and financial assets at amortized cost other than loans and contingent receivables. The estimate involves calculating the potential credit losses that could be observed on a financial instrument due to differences between the future cash flows under the original contract and the cash flows expected to be received, always ensuring at all times that the results obtained are appropriate to the reality of the transactions, the current economic environment and the available forward-looking information. This model uses a dual measurement approach in which the impairment provision is measured as follows: • Credit loss expected at 12 months: it represents expected credit losses arising from default events on a financial instrument that may arise within 12 months from the reporting date. • Lifetime expected credit loss: it represents the expected credit losses arising from default events over the expected life of a financial instrument. At each reporting date, an entity must measure the provision as equal to the 'lifetime expected credit loss' if the credit risk on that financial instrument has increased significantly since initial recognition. Otherwise, if the credit risk of a financial instrument has not increased significantly at the reporting date since initial recognition, an entity shall measure the loss allowance for that financial instrument at an amount equal to 'expected credit loss over the next 12 months'. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 38
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued When making such an assessment, an entity compares the default risk of a financial instrument at the reporting date with that of its initial recognition, as well as considering reasonable and tenable information made available without unnecessary cost or effort, indicating the growth of credit risk since its initial recognition (on a group or individual basis). Based on changes in credit quality, IFRS 9 describes a 'three-step' impairment model according to the following diagram: Change in credit quality since initial recognition Phase 1 Phase 2 Phase 3 Initial recognition Significant increase in credit risk since initial recognition Credit-impaired assets Credit loss expected in 12 months Lifetime credit loss Lifetime credit loss Reasonable and tenable information refers to information readily available at the reporting date without unreasonable cost or effort, including information about past events, current conditions and forecasts of future economic conditions. When contractual payments are overdue by 30 days or more, the Bank considers that the credit risk of a financial asset has increased significantly, but this is not the only indicator. Measurement of expected credit loss Expected credit loss estimates the weighted probability of credit losses over the financial instrument's expected life, that is, the present value of all cash shortfalls. The three components of the measurement of expected credit loss are: • PNP: The probability of default estimates the probability of non-performance over a given time frame. • LGD: Loss-given default estimates the loss that would occur in the event of a default at a given time. • EAD: Exposure at default is an estimate of the exposure at a future date of non-performance, considering expected exposure changes after the reporting date, including repayments of principal and interest, whether contractually scheduled or otherwise, and interest on defaults. The parameters used for the calculation of impairment provisions were developed based on the structure of the internal models used and take into account the experience acquired in the regulatory and management areas, as well as the stages in which each financial asset is classified, including forward-looking information, point-in-time (PIT) view, multiple scenarios, calculation of losses for the entire life of the operation through lifetime PNP, among others. Collateral and other credit enhancements are considered to measure expected credit loss. Determination of a significant increase in risk For the classification in phase 2, an assessment of whether there is a significant increase in credit risk (SICR) from the initial recognition of the transactions is undertaken. For this, a series of principles that ensure that all financial instruments are subject to this assessment is used, which considers the particularities of each portfolio and type of product based on various quantitative and qualitative indicators. All of this is subject to the expert judgment of analysts, who set the thresholds under appropriate management integration and implement it under the approved governance. The judgment and criteria used to establish thresholds are based on several principles. The principles are as follows: • Universal: all financial instruments with a credit rating must be assessed for their potential SICR. • Proportional: the definition of the SICR should consider each portfolio's particularities. • Materiality: its implementation should also be consistent with each portfolio's relevance to avoid unnecessary cost or effort. • Holistic view: the selected approach should combine the most relevant aspects of credit risk (i.e. quantitative and qualitative). • Application of IFRS 9: the approach should consider the features of IFRS 9, focusing on a comparison with credit risk at initial recognition and considering forward-looking information. • Risk management integration: criteria should be consistent with those metrics considered in day-to-day risk management. • Documentation: Appropriate documents must be prepared Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 39
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued To classify a financial instrument in phase 2, we consider the following criteria: • Quantitative criteria: changes in the risk of a default occurring over the expected life of the financial instrument are analyzed and quantified relative to its level of credit risk at inception. For this purpose, quantitative thresholds have been defined for the portfolios. These thresholds can be expressed as an absolute or relative increase in the probability of default. • Qualitative criteria: using expert judgment, we use various indicators aligned with those used in ordinary credit risk management (defaults over 30 days, refinancing, etc.). • Definition of default: this definition entails the application of various criteria to classify exposures as phase 3, including transactions in default for 90 consecutive days or identifying other criteria that demonstrate that the counterparty can meet all of its financial obligations. • Expected life of the financial instrument: we estimate the expected life of a financial instrument considering all contractual terms (e.g. prepayments, duration, repurchase agreements, etc.). Recognition of expected credit loss An entity shall recognize in its financial results a gain or loss caused by value impairment as the amount of the expected credit loss (or releases) by which the value is adjusted given the losses that have occurred by the reporting date to capture the amount that requires recognition accurately. For assets measured at fair value through other comprehensive income, the book value of the instruments is understood as the fair value. Therefore, the recognition of impairment does not affect the carrying amount of such instruments and is reflected as a movement between other comprehensive income (a deduction from fair value) and results at each reporting date. In the case of assets measured at amortized cost, impairment is presented through a complementary account that reduces the asset's value. 19. Impairment of non-financial assets The Bank's non-financial assets are reviewed at each reporting date of the Interim Consolidated Financial Statements for indications of impairment (i.e., when the carrying amount exceeds the recoverable amount). If such indications exist, the asset's recoverable amount is estimated to determine the extent of the impairment loss. The recoverable amount is the higher of fair values minus disposal costs and value in use. In assessing value in use, estimates of cash inflows or outflows shall be discounted to present value using the pre-tax discount rate that reflects the current market assessment of the time value of money and the specific risks for which estimates of future cash flows have not been adjusted. If the recoverable amount of an asset is estimated to be lower than its carrying amount, the carrying amount is reduced to the recoverable amount. The impairment loss is recognized immediately in profit or loss. In relation to other assets, impairment losses recognized in prior periods are evaluated at each reporting date for any indication that the loss has decreased and should be reversed. The increase in the carrying value of an asset other than goodwill attributed to a reversal of the impairment loss will not exceed the carrying amount that could have been obtained (net of amortization or depreciation) if an impairment loss had not been recognized for said asset in previous periods. The impairment loss recognized in goodwill will not be reversed. 20. Provisions, contingent assets and liabilities Provisions are liabilities whose amount or maturity are uncertain. These provisions are recognized in the Interim Consolidated Statements of Financial Position when all the following requirements are met: i. It is a current obligation (legal or constructive) as a result of past events and, ii. as of the publication date of the financial statements, the Bank will probably have to expend resources to settle the obligation and; iii. the amount of these resources can be reliably measured. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 40
NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued Contingent assets or contingent liabilities encompass all potential rights or obligations arising from past events. These are only confirmed if one or more uncertain future events occurs, which are not within the Bank's control. The Interim Consolidated Financial Statements reflect all significant provisions for which the probability of meeting the obligation is estimated to be more likely than not. Provisions are quantified using the best available information regarding the consequences of the event giving rise to them and are reviewed and adjusted at the end of the accounting period. Provisions are used when the liabilities for which they were originally recognized are settled. Partial or total reversals are recognized when such liabilities cease to exist or are reduced. Provisions are classified according to the obligation covered as follows: • Provisions for employee benefit obligations. • Provisions for lawsuits and litigations. • Provisions for operational risk. • Provisions for mandatory dividends. • Provisions for contingent loan risks. • Provisions for contingencies. 21. Income tax and deferred taxes The Bank recognizes, where appropriate, deferred tax assets and liabilities for the estimated future tax effects attributable to differences between the carrying amounts of assets, liabilities and their tax bases. Deferred tax assets and liabilities are calculated using the tax rate applied in the year the deferred tax assets and liabilities are realized or settled according to current tax legislation. The future effects of tax legislation or tax rate changes are recognized in deferred taxes from when the law approving such changes is published. Current tax assets relate to provisional payments in excess of the provision for income tax or other income tax credits, such as training expenses or donations to universities. In addition, the monthly provision payments to be recovered for profits absorbed by tax losses should be included. In the case of liabilities, they correspond to the provision for income tax calculated based on the tax results for the period, minus the mandatory or voluntary provisional payments and other credits applied to this obligation. For presentation in the Interim Consolidated Statements of Financial Position, in accordance with IAS12, tax positions should be offset at the individual taxable entity level, as appropriate, and the resulting net balances for each taxable entity should then be aggregated at the consolidated level. 22. Employee benefits i. Post-employment benefits – Defined Benefit Plan: According to the current collective labor covenant and other agreements, Banco Santander-Chile has an additional benefit available for its main executives, consisting of a pension plan, aiming for them to have the necessary funds for a supplementary pension upon retirement. Plan Features: The main features of the Post-Employment Benefits Plan promoted by the Banco Santander-Chile are: i. Aimed at the Bank's upper management. ii. The general requirement is that the beneficiary must still hold their position within the Bank by the time they turn 60 years old. iii. The Bank will contract a mixed collective insurance policy (life and savings) for each executive, with the contracting party and beneficiary being the Group company to which the executive belongs. Periodic contributions will equal the amount each manager commits to their voluntary contribution plan. iv. The Bank will be responsible for granting the benefits directly.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued To determine the present value of the defined benefit obligation and the current service cost, the projected unit credit method is used. The components of defined benefit cost include: • Current and past service costs are recognized in profit or loss for the period. • Net interest over the net defined benefit liability (asset), recognized in profit or loss for the period. • The new net defined benefit liability (asset) measurements include: (a) actuarial gains and losses; (b) the performance of the plan's assets, and (c) changes in the effect of the asset ceiling, which are recognized in other comprehensive income. The net defined benefit liability (assets) is the deficit or surplus, calculated as the difference between the defined benefit obligation's present value minus the plan assets' fair value. The plan assets comprise the insurance policies contracted by the Bank through an unrelated third party. These assets are held by an entity legally separated from the Bank and exist solely to pay employees their benefits. The Bank recognizes the present service cost and the net interest in the item "Expenses from obligations to employees" in the Interim Consolidated Statements of Income. The plan's structure does not generate actuarial gains or losses. The plan's performance is established and fixed during the period; consequently, there are no changes to the asset's ceiling. Accordingly, there are no amounts recognized in other comprehensive income. The post-employment benefits obligation recognized in the Interim Consolidated Statements of Financial Position, represents the deficit or surplus in the defined benefit plans of the Bank. Any surplus resulting from the calculation is limited to the present value of any economic benefits available regarding the plan's reimbursements or reductions to future contributions. When employees abandon the plan before meeting the requirements to become eligible for the benefit, the Bank's contributions to these plans decreases. ii. Severance payments: Severance payments for years of employment are recorded only when they effectively occur or upon the availability of a formal and detailed plan in which the fundamental modifications to be made are identified, provided that such plan has already started to be implemented, its principal features have been publicly announced, or objective facts about its activation are known. iii. Cash-settled share-based payments The Bank allocates cash-settled share-based payments to certain executives of the Bank and its Subsidiaries under IFRS 2: Share- based payments. Accordingly, the Bank measures the services received and the obligation incurred at fair value. Until the obligation is settled, the Bank calculates the fair value at the end of each reporting period and at the date of settlement, recognizing any change to fair value in the income statement for the period. 23. Use of Estimates Preparing the Interim Consolidated Financial Statements requires the Bank's Management to make estimates and assumptions that affect the application of the accounting standards and the reported values of assets, liabilities, revenues and expenses. Accordingly, actual results may differ from these estimates. In certain cases, the generally accepted accounting standards require that assets or liabilities be recorded or disclosed at their fair value. The fair value is the price received to sell an asset or paid to transfer a liability in an orderly transaction between informed market participants at the measurement date. When available, quoted market prices in active markets have been used for measurement. When the trade prices of an active market are not available, the Bank estimates such values based on the best information available, including internal modelling and other valuation techniques. The Bank has established provisions to cover potential credit loss per the regulations issued by the FMC. These allowances must be regularly reviewed, considering factors such as changes in the nature and volume of the loan portfolio, trends in forecasted portfolio quality, credit quality, and economic conditions that may adversely affect the borrowers' ability to pay. Increases in the allowances for loan loss are reflected as 'Provisions for loan loss' in the Interim Consolidated Statements of Income.

NOTE 02 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued Loans are written off when the contractual rights for the cash flows expire. Nevertheless, the Bank will charge off per Title II of Chapter B-2 of the CASB issued by the FMC for loans and accounts receivable from clients. Charge-offs are recorded as a reduction of credit risk provisions. The Bank's Management regularly reviews the relevant estimates and assumptions to calculate provisions quantifying certain assets, liabilities, revenues, expenses, and commitments. Revised accounting estimates are recorded in the period the estimate is revised and in any future period affected. These estimates are based on the best available information and mainly refer to the following: • Allowances for loan loss (Notes N° 13 and 41). • Impairment loss on certain assets (Notes N°11, 13, 15, 16, 17, 39 and 40). • The useful lives of tangible and intangible assets (Notes N° 15, 16 and 17). • The fair value of assets and liabilities (Notes N° 8, 11, 12, 21 and 44). • Commitments and contingencies (Note N° 29). • Current and deferred taxes (Note N°18). 24. Earnings per share Basic earnings per share are calculated by dividing the net income attributable to the equity holders of the Bank by the weighted average number of shares outstanding during the reported period. Diluted earnings per share are calculated similarly to basic earnings, but the weighted average number of outstanding shares is adjusted to consider the potential diluting effect of stock options, warrants, and convertible debt. As of June 30, 2026, and 2025, and as of December 31, 2025, the Bank did not hold any instruments that have a dilutive effect on equity. 25. Temporary acquisition (assignment) of assets Purchases (sales) of financial assets under non-optional repurchase agreements at a fixed price (repos) are recorded in the Interim Consolidated Statements of Financial Position as a financial assignment (receipt) based on the nature of the debtor (creditor) under 'Deposits in the Central Bank of Chile', 'Deposits in financial institutions' or 'Loans and receivables from customers' ('Deposits from Central Bank of Chile', 'Deposits from financial institutions' or 'Deposits'). The difference between the purchase and sale prices is recorded as financial interest over the contract's life. 26. Assets and investment funds managed by the Bank The assets managed by the different companies that form part of the Bank's consolidation perimeter (Santander S.A. Sociedad Securitizadora) that are owned by third parties are not included in the Interim Consolidated Statements of Financial Position. The commissions generated by this activity are included in the balance of 'Fee and commission income' in the Interim Consolidated Statements of Income. 27. Provision for mandatory dividends The Bank recognizes a liability (provision) for minimum or mandatory dividends based on the provisions of Article 79 of the Chilean Corporations Law (Ley de Sociedades Anónimas), consistent with the Bank’s internal dividend policy, which stipulates that at least 30% of net income for the year shall be distributed, unless otherwise agreed at the respective Shareholders’ Meeting by the unanimous vote of the issued shares. For 2026 and 2025, the percentage used for the minimum dividend provision is 60%. This provision is recorded as a reduction of “Retained earnings” under the caption “Provision for dividends, interest payments and revaluation of equity financial instruments” within the Interim Consolidated Statements of Changes in Equity.

NOTE 03 - NEW ACCOUNTING PRONOUNCEMENTS ISSUED AND ADOPTED OR ISSUED AND NOT YET ADOPTED 1. Pronouncements issued and adopted As of the date these Interim Consolidated Financial Statements were published, the new accounting pronouncements issued by both the FMC and the International Accounting Standards Board, which the Bank has fully adopted, are set out below: a. Accounting Standards issued by the Financial Markets Commission. NCG No. 537 – Amends Chapter 8-41 of the Updated Compilation of Bank Regulations (UCBR) and Circular No. 1 for Non-Bank Card Issuers regarding the determination of a formula for calculating the minimum payment amount on credit cards, and the exceptional situations in which debtors will be released from this obligation. On June 4, 2025, the FMC issued this amendment, aimed at including a formula for calculating the minimum payment amount on credit cards. NCG No. 537 amends Chapter 8-41 of the UCBR and Circular No. 1 for Non-Bank Issuers. The amendment to Chapter 8-41 of the UCBR includes a new section 5, “Special rules on credit cards”, which establishes a formula and the variables to be considered in calculating the minimum amount that borrowers of money credit operations —originating from the use of credit cards through a revolving or consolidated credit line— must pay monthly to avoid delinquency. The minimum payment is the lowest amount the cardholder must pay each month to remain current. The mathematical formula consists of a percentage of the total billed amount, which requires defining the “non-financeable amount” (NFA) and the “financeable amount” (FA), where: Minimum Payment ≥ (100% × NFA) + (5% × FA) This regulation came into force on June 4, 2025 with gradual application starting 12 months after its publication, following the mathematical expression for calculation set out in NCG No. 537. The Bank has completed the implementation of this regulation, within the established deadlines. b. Accounting Standards Issued by the International Accounting Standards Board. Amendment to IFRS9 and IFRS7 - amendment to the Classification and Measurement of Financial Instruments. The modifications are: Amendments to IFRS 9 – Classification of Financial Assets: - Financial assets with ESG and similar features: Financial assets with contingent events may pass the SPPI Test if their cash flows are SPPI both before and after the contingent event, and the cash flows do not differ significantly from those of a similar asset without such a contingent event. - Derecognition of financial liabilities settled through electronic transfer: An accounting policy option is allowed to derecognize such liabilities before the settlement date if certain conditions are met. If this option is chosen, it must be applied to all agreements settled through the same electronic payment system. Amendments to IFRS 7: - Investments in equity instruments designated at fair value through OCI: Entities must disclose the fair value result presented in OCI during the period, distinguishing the result from changes in fair value from the result due to derecognition. - Contractual terms that may change the timing or amount of contractual cash flows: Disclosure is required for contractual terms that may modify the timing or amount of cash flows upon the occurrence (or non-occurrence) of a contingent event that is not directly related to changes in basic lending risks or costs. This applies to assets measured at amortized cost or fair value through OCI and to financial liabilities measured at amortized cost. These amendments are effective for annual periods beginning on or after January 1, 2026. Early application is permitted. The Bank has determined that there are no significant impacts related to the adoption of this standard. Annual Improvements to IFRS – Volume 11. This standard, issued on July 18, 2024, by the International Accounting Standards Board (IASB), addresses minor but necessary non-urgent amendments to the following five Standards: IFRS 1 – First-time Adoption of International Financial Reporting Standards IFRS 7 – Financial Instruments: Disclosures IFRS 9 – Financial Instruments IFRS 10 – Consolidated Financial Statements IAS 7 – Statement of Cash Flows Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 44
NOTE 03 - NEW ACCOUNTING PRONOUNCEMENTS ISSUED AND ADOPTED OR ISSUED AND NOT YET ADOPTED, continued The published amendments will be effective for annual periods beginning on or after January 1, 2026, with early application permitted. The Bank has determined that there are no significant impacts related to the adoption of this standard. IFRS 9 and IFRS 7 – Renewable Energy Power Purchase Agreements. Issued on December 18, 2024, the amendments include: Amendments to IFRS 9 – Financial Instruments: - The own-use requirements in IFRS 9 have been modified to include factors that an entity must consider when applying the scope of IFRS 9 (paragraph 2.4) to renewable energy power purchase agreements, for both the purchase and receipt of renewable electricity. - The hedge accounting requirements have also been amended to allow an entity to use a renewable electricity contract as a hedging instrument by designating a variable volume of forecast electricity transactions as the hedged item, provided specified criteria are met, and measuring the hedged item using the same volume assumptions as those used for the hedging instrument. Amendments to IFRS 7 – Financial Instruments: Disclosures: - Specific qualitative and quantitative disclosure requirements are introduced for electricity contracts, depending on their nature and specified characteristics. The published amendments will be effective for annual reporting periods beginning on or after January 1, 2026, with early application permitted. The Bank has determined that there are no impacts arising from this standard. 2. Issued pronouncements which have not yet been adopted As of the reporting date of these Interim Consolidated Financial Statements, new International Financial Reporting Standards had been published, as well as their interpretation and the FMC standards, which were not mandatory as of June 30, 2026. Accordingly, while the IASB permits an early application in some cases, the Bank has not undertaken its application by such date. a. Accounting Standards issued by the Financial Markets Commission There are no new FMC regulations that apply to the present Consolidated Interim Financial Statements. b. Accounting Standards issued by the International Accounting Standards Board IFRS 18 – Presentation and Disclosures in Financial Statements. On April 9, 2024, the IASB issued IFRS 18, which replaces IAS 1: Presentation of Financial Statements. IFRS 18 introduces three sets of new requirements aimed at improving the information on financial performance and providing a better basis for analyzing and comparing companies: • Improved comparability of the statement of profit or loss • Greater transparency of management-defined performance measures • More useful aggregation of information in the financial statements IFRS 18 becomes effective for annual reporting periods beginning on or after January 1, 2027, with early application permitted. The Bank is in the process of analyzing this standard. IFRS 19 Subsidiaries without Public Accountability: Disclosures. This standard specifies the disclosure requirements applicable to subsidiaries that do not have public accountability and whose parent prepares consolidated financial statements that are publicly available and comply with IFRS Accounting Standards. On August 19, 2025, amendments were issued permitting subsidiaries without public accountability to apply IFRS Accounting Standards with reduced disclosure requirements, thereby exempting them from most of the disclosure requirements contained in other IFRS Accounting Standards. These amendments enable eligible subsidiaries to reduce their disclosure requirements and align the standard's effective date. With these updates, IFRS 19 has been aligned to incorporate disclosure requirements issued up to January 1, 2027, when the standard will become fully effective. This standard is effective for annual reporting periods beginning on or after January 1, 2027, with earlier application permitted. The Bank is currently assessing the impact of this standard.

NOTE 03 - NEW ACCOUNTING PRONOUNCEMENTS ISSUED AND ADOPTED OR ISSUED AND NOT YET ADOPTED, continued Translation to a Hyperinflationary Presentation Currency (Amendments to IAS 21). Through amendments issued on November 13, 2025, the IASB amended IAS 21 to clarify how an entity translates its financial statements when the presentation currency (rather than the functional currency) is hyperinflationary. These amendments address a gap in the previous requirements, which only addressed hyperinflation in the functional currency. The amendments are effective for annual reporting periods beginning on or after January 1, 2027, with earlier application permitted. The Bank has assessed that these amendments are not applicable to the Bank under the current circumstances. Amendments to IAS 28: Amendments relating to the Fair Value Option for Investments in Associates and Joint Ventures. Through amendments issued on June 26, 2026, the IASB made targeted amendments to clarify which investments in associates and joint ventures may be measured using the fair value option provided in IAS 28 Investments in Associates and Joint Ventures. The IASB identified diversity in practice regarding the interpretation of the scope of investments to which this option applies. Consequently, the amendments clarify that entities whose principal business activity consists of investing in specific types of assets (as listed in paragraph 49(a) of IFRS 18) may elect to measure an investment in an associate or a joint venture at fair value through profit or loss in accordance with IFRS 9. These amendments will become effective when an entity first applies IFRS 18. The Bank is currently assessing the scope of these amendments in the context of its IFRS 18 implementation.

The assets, liabilities and results of each segment include items directly attributable to the relevant segment, as well as those that can be allocated on a reasonable basis. A business segment comprises customers to whom a differentiated product offering is directed, but who are homogeneous in terms of performance and whose results are measured on a similar basis. As of March 31, 2026, the Bank modified the identification of its operating segments in order to reflect changes in its internal management structure and in the manner in which the chief operating decision maker (“CODM”) evaluates performance and allocates resources. Accordingly, comparative information has been restated for consistency with the presentation of the current period. Management believes that this new presentation provides more relevant information to users of the financial statements.

Accordingly, the Bank measures services received, and liabilities incurred at fair value. Until settlement of the liability, the Bank determines the liability's fair value at the end of each reporting period and on the settlement date, with any fair value changes recognized in the period results. Pension plan The Bank has an additional benefit available to its senior executives, consisting of a pension plan with funds to provide for a better complementary pension upon retirement. In this respect, the Bank will complement the voluntary contributions made by beneficiaries for their future pension with an equal contribution. Executives shall earn the right to receive this benefit only if they meet the following concurrent conditions: a. Aimed at the Group's senior management. b. The general requirement for eligibility is to be still employed when they are 60 years old. c. The Bank will contract a mixed collective insurance policy (life and savings) for each executive, with the contracting party and beneficiary being the Group company to which the executive belongs. In the event of termination of the employment relationship between the executive and the respective company before meeting the conditions described above, no entitlement shall accrue to them under this benefit plan. Exceptionally, in the event of the manager's death or their total or partial disability, the manager or their heirs shall be entitled to receive this benefit as the case may be. The Bank will contribute to this benefit plan based on mixed group insurance policies, the beneficiary of which is the Bank. The life insurance company with which these policies are contracted is unrelated to the Bank or any other Group company. The Bank's entitlements under the plan as of June 30, 2026, and December 31, 2025 amounted to Ch$4,180 million and Ch$3,462 million, respectively.

NOTE 37 - EXPENSES FROM OBLIGATIONS TO EMPLOYEES, continued Calculation method: The projected unit credit method is used, which considers each year of service as generating an additional unit of benefit entitlement and values each unit separately. It is calculated according to the fund contribution that considers as the main parameters the factors related to the legal annual pension ceiling, the years of service, age and annual income of each unit valued individually. Actuarial assumptions used: Actuarial assumptions regarding demographic and financial variables are unbiased and mutually compatible. The most significant actuarial assumptions considered in the calculations were: The assets related to the savings fund contributed by the Bank to Compañía de Seguros Zurich, for defined benefit plans, are presented net of the associated obligations. The assumptions used correspond to.

NOTE 43 - TRANSACTION WITH RELATED PARTIES The Bank's "related parties" include, in addition to its subsidiaries and associates, "key personnel" of the Bank's Management (members of the Bank's Board of Directors and Managers of Banco Santander-Chile and its affiliates, along with their close relatives), as well as entities over which key personnel may exercise significant influence or control. Additionally, the Bank has considered the various companies that form part of the Santander Group worldwide as related parties, with the understanding that they all have a common parent company, namely Banco Santander S.A. (based in Spain). Article 89 of the Chilean Corporation Law, which also applies to banks, establishes that any transaction with a related party must be carried out under fair conditions, similar to those normally prevailing in the market. Furthermore, Article 84 of the General Banking Law establishes limits loans that may be granted to related parties and prohibits granting loans to the Bank's directors, general manager, or general representatives. The Bank's transactions with its related parties are listed below. For ease of understanding, we have divided the information into four categories: Santander Group Companies This category includes all companies belonging to the Santander Group worldwide, and therefore also includes those companies over which the Bank exercises some degree of control (subsidiary and special-purpose entities). Associated Companies This category includes those entities where the Bank, as indicated in Note 01 b) of these Consolidated Financial Statements, exercises some degree of significant influence over them. These entities, in general, correspond to the so-called "business support companies." Key Personnel This category includes members of the Bank's Board of Directors and executives of Banco Santander-Chile and its affiliates, along with their close relatives. It takes into account the limitations imposed by Chapter 12-12 of the UCBR. Other This category includes related parties not included in the groups described above and, in general, those entities over which key personnel may exercise significant influence or control. The terms of transactions with related parties are equivalent to those found in arm's-length transactions, or the corresponding in- kind compensation has been allocated.

NOTE 44 - FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction in the principal (or most advantageous) market at the measurement date under current market conditions (i.e., an exit price), regardless of whether that price is directly observable or estimated using another valuation technique. Fair value measurement assumes that the sale of the asset or transfer of the liability occurs in the principal market for the asset or liability or in the most advantageous market for the asset or liability. For financial instruments without available market prices, fair values have been estimated using recent transactions in similar instruments or, if not possible, current values or other valuation techniques based on mathematical valuation models sufficiently tested by the international financial community. When using these models, the specific characteristics of the asset or liability being valued are taken into account, and in particular, the different types of risks associated with the asset or liability. These techniques are inherently subjective and significantly affected by the assumptions used, including the discount rate, estimates of future cash flows, and prepayment assumptions. Therefore, estimated fair value of an asset or liability not exactly matching the price at which the asset or liability could be delivered or settled at the valuation date and may not be justified by comparison with independent markets. Determination of the fair value of financial instruments The following table shows a comparison between the book value of the Bank's financial assets and liabilities and their corresponding fair values as of June 30, 2026, and December 31, 2025: As of June 30, 2026 As of December 31, 2025 Book value Fair value Book value Fair value Ch$mn Ch$mn Ch$mn Ch$mn Assets Financial assets held for trading at fair value through profit or loss 11,100,132 11,100,132 11,594,405 11,594,405 Financial derivatives contracts 10,588,911 10,588,911 10,879,777 10,879,777 Debt financial instruments 511,221 511,221 714,628 714,628 Financial assets at fair value through other comprehensive income 5,072,701 5,072,701 3,889,952 3,889,952 Debt financial instruments 4,622,947 4,622,947 3,598,366 3,598,366 Other financial instruments 449,754 449,754 291,586 291,586 Financial derivative contracts for hedge accounting 304,348 304,348 261,192 261,192 Debt financial instruments at amortized cost 46,580,881 46,769,359 45,544,899 46,090,804 Rights for repurchase agreements and securities loans 861,341 861,684 427,983 428,483 Debt financial instruments 5,676,311 5,743,710 5,525,242 5,593,724 Interbank loans and receivables from clients 40,043,229 40,163,965 39,591,674 40,068,597 Guarantees provided for derivative financial transactions 1,595,160 1,595,160 2,075,671 2,075,671 Liabilities Financial liabilities held for trading at fair value through profit or loss 10,049,334 10,049,334 10,587,308 10,587,308 Financial derivatives contracts 10,049,334 10,049,334 10,587,308 10,587,308 Financial derivative contracts for hedge accounting 818,324 818,324 912,716 912,716 Financial liabilities at amortized cost 49,084,766 49,555,210 47,260,235 47,809,603 Deposits and other demand liabilities 13,943,771 13,943,771 14,075,590 14,075,590 Time deposits and other term equivalents 18,447,020 18,600,756 16,493,783 16,678,683 Obligations under repurchase agreements and securities lending 3,232,935 3,340,697 2,755,243 2,836,063 Interbank borrowing 3,378,281 3,493,767 3,434,237 3,564,731 Debt and regulatory capital financial instruments issued 9,868,741 9,962,201 10,277,061 10,430,215 Other financial liabilities 214,018 214,018 224,321 224,321 Guarantees received for financial derivative transactions 1,539,079 1,539,079 1,541,061 1,541,061 Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 180
NOTE 44 - FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES, continued Fair value approximates carrying amount in the following items, due to their short-term nature, in the case of: cash, bank deposits, and transactions in the process of settlement. Additionally, the fair value estimates presented above do not attempt to quantify the value of the Bank’s earnings generated by its business or future activities, and therefore do not represent the value of the Bank as a going concern. Below is a description of the methods used to estimate the fair value of financial instruments. 1. Debt financial instruments The estimated fair value of these financial instruments was established using market values or estimates from a readily available dealer or quoted market prices for similar financial instruments. The investments are valued at book (as recorded) value because they are not considered to have a fair value significantly different from their recorded value. Additional variables and elements (where applicable) were considered in estimating the fair value of debt investments, including estimates of prepayment rates and the issuers' credit risk. 2. Loans and receivables from clients and Interbank loans The fair value of commercial loans, mortgage loans, credit cards, and consumer loans is measured using discounted cash flow analysis. For this purposes, prevailing market interest rates are used, taking into account the product, term, amount, and similar credit quality. The fair value of loans with a past due period of 90 days or more is measured using the market value of the associated collateral, discounted at the rate and expected maturity. For variable-rate loans with frequently changing interest rates (monthly or quarterly) and not subject to significant credit risk, the estimated fair value is based on their carrying amount. The carrying amounts and fair values are presented net of provisions for credit risk. 3. Deposit and other demand obligations The disclosed fair value of non-interest-bearing deposits and savings accounts is the amount payable at the reporting date and, therefore, equals the recorded amount. The fair value of time deposits is calculated using the discounted cash flow method, which applies current interest rates currently offered to a schedule of monthly maturities expected in the market. 4. Short- and long-term debt instruments issued The fair value of these financial instruments is calculated using discounted cash flow analysis based on current incremental borrowing rates for similar types of loan agreements with similar maturities. 5. Financial derivatives and accounting hedging contracts The estimated fair value of the foreign exchange forward contracts was calculated using quoted market prices for financial instruments with similar characteristics. The fair value of interest rate swaps represents the estimated amount that the Bank determines as the exit price in accordance with IFRS 13. If there are no quoted market prices (direct or indirect) for any derivative instrument, the respective fair value estimates have been calculated using valuation models and techniques such as Black-Scholes, Hull and Monte Carlo simulations and considering relevant inputs such as option volatility, observable correlations between underlying assets, counterparty credit risk, implied price volatility, speed with which volatility reverts to its mean value, linear relationship (correlation) between the value of a variable. Fair value measurement and hierarchy IFRS 13, "Fair Value Measurement," establishes a fair value hierarchy that segregates the inputs and/or assumptions of valuation techniques used to measure the fair value of financial instruments. The hierarchy gives highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and lowest priority to measurements that involve significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 181
NOTE 44 - FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES, continued • Level 1: Inputs are quoted (unadjusted) prices in active markets for identical assets and liabilities for which the Bank has access at the measurement date. • Level 2: Inputs other than quoted prices included in Level 1 that are observable for assets or liabilities, directly or indirectly. • Level 3: Unobservable inputs for the asset or liability. The estimated fair value of the foreign exchange forward contracts was calculated using quoted market prices for financial instruments with similar characteristics. The fair value of interest rate swaps represents the estimated amount the Bank expects to receive or pay to terminate the contracts or agreements, taking into account the term structures of the interest rate curve, volatility of the underlying asset, and the credit risk of the counterparties. In cases where quotations cannot be observed, management makes its best estimate of the market price using its own internal models, which, in most cases, use data based on observable market parameters as significant inputs (Level 2) and, in limited cases, use significant inputs that are not observable in market data (Level 3). Various techniques are used to arrive at this estimate, including extrapolation of observable market data. Financial instruments at fair value and determined by published quotes in active markets (Level 1) include: • Instruments of the Chilean Central Bank and the General Treasury of the Republic. • Foreign instruments issued. • Mutual funds. If the instruments are not 100% market-observable, however, the price is a function of other prices that are market-observable (Level 2). The following financial instruments are classified as Level 2: Type of financial instrument Valuation model used Description Private bonds Present value of cash flows Internal rates of return ("IRRs") are provided by independent pricing source service entity according to the following criterion: On the valuation day, if there are one or more valid transactions in the Santiago Stock Exchange for a given mnemonic code, the reported rate is the weighted average of said rates. If there are no valid transactions for a given mnemonic data on the valuation day, the reported rate is an 'IRR baseline' from a reference structure plus a 'Model Spread' based on information from historical spreads of the same or similar documents. Time deposits Present value of cash flows Internal rates of return ("IRRs") are provided by independent pricing source service entity according to the following criterion: On the valuation day, if there are one or more valid transactions in the Santiago Stock Exchange for a given mnemonic code, the reported rate is the weighted average of said rates. If there are no valid transactions for a given mnemonic code on the valuation day, the reported rate is an 'IRR baseline' from a reference structure plus a 'Model Spread' based on the 'Issuer curves'. Constant Maturity Swap (CMS), Forward FX and Inflation, Cross Currency Swap (CCS), Interest Rate Swap (IRS) Present value of cash flows Rates (IRR) are provided by ICAP, GFI, Tradition and Bloomberg according to the following criteria: The published market prices are used to construct the valuation curve using the bootstrapping method, and then this curve is used to value the various derivatives. FX Options Black-Scholes Formula adjusted by the volatility smile (implied volatility). BGC Partners provide prices (volatilities) according to the following criteria: The volatility surface is built through interpolation using published market prices, and these volatilizes are then used to value the options. Guarantees for threshold transactions, guarantee deposits Present value of cash flows Transactions related to derivatives contracts such as Constant Maturity Swap (CMS), Forward FX and Inflation, Cross Currency Swap (CCS), Interest Rate Swap (IRS) and FX Options.

NOTE 44 - FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES, continued In limited cases, unobservable inputs are used in market data (Level 3). Various techniques are used to perform this estimation, including extrapolation of observable market data or a mix of observable data. The following financial instruments are classified as Level 3: Type of financial instrument Valuation model used Description Caps/Floors/Swaptions Black Normal model for Cap/Floors and Swaptions There is no observable input of implied volatility. Black-Scholes There is no observable input of implied volatility. Hull-White Hybrid HW model for rates and Brownian motion for FX. There is no observable input of implied volatility. Implicit Forward Rate Agreement (FRA) Start Fwd unsupported by Murex (platform) due to the UF forward estimate. CCS, IRS, CMS in Active Bank Rate (TAB) Present value of cash flows Valuation obtained using yield curve interpolating to maturity of flows. Nevertheless, TAB is not a directly observable variable nor correlated to any market input. Present value of cash flows Valuation using prices of instruments with similar characteristics, plus a liquidity discount rate. CCS (maturities over 30 years) Present value of cash flows Rates (IRR) are provided by ICAP, GFI, Tradition and Bloomberg according to the following criteria: The published market prices are used to construct the valuation curve using the bootstrapping method and then this curve is used to value the various derivatives. Receivables accounts valued at fair value Present value of cash flows Measured by discounting the estimated cash flow using the interest rate of the new contracts. Mortgage bonds Present value of cash flows The rates (IRR) are provided by RiskAmérica according to the following criteria: If on the valuation date there is one or more valid transactions on the Santiago Stock Exchange for a specific security code, the reported rate is the weighted average (by amount) of the observed rates. If there are no valid transactions for a given security code on the valuation date, the reported rate is a "base IRR" derived from a reference curve, plus a "Model Spread" based on historical spread data for the same instrument or similar ones. The Bank estimates that any changes in unobservable criteria for instruments classified at Level 3 would not result in significant differences in the fair value measurement.

The methods and assumptions for estimating fair value are defined below: • Loans and amounts owed by credit institutions and customers: Fair value is estimated for groups of loans with similar characteristics. Fair value was measured by discounting the estimated cash flow using the new contract interest rate. First, the future cash flow of the current loan portfolio is estimated using contractual rates, and then the new loans distributed at the risk- free interest rate are incorporated into the (risk-free) yield curve to calculate the loan portfolio at fair value. Regarding behavioral assumptions, it is important to emphasize that a prepayment rate is applied to the loan portfolio, thus providing a more realistic future cash flow: • Deposits and liabilities with banks: The fair value of deposits was calculated by discounting the difference between cash flows on a contractual basis and current market rates for instruments with similar maturities. For variable-rate deposits, the carrying amount was considered to approximate fair value. • Debt instruments issued and other financial obligations: The fair value of long-term loans was estimated using discounted cash flows at the market interest rate with similar terms and maturities. The valuation techniques used to estimate each level are defined in Note 2. There were no transfers between Levels 1 and 2 as of June 30, 2026, and December 31, 2025.

NOTE 47 - RISK MANAGEMENT AND REPORTING General information For Banco Santander, risk management is the core of its business. The Bank's corporate governance continually optimizes its risk management and control system, based on the Basel Committee's principles, an integrated risk culture, a robust governance structure, and advanced tools, with the goal of ensuring responsible conduct in response to economic changes, customer demands, and legal regulations. The Board of Directors assumes ultimate responsibility in this area, including the approval of risk appetite, the regulatory framework, and the promotion of a consistent organizational culture. The Bank's risk management and control are based on the following principles, that consider both regulatory requirements and market best practices and must be applied at all times: 1. All employees are responsible for risk management and must know and understand the risks generated by their daily activities, avoiding taking risks whose impact is unknown or exceeding the limits of the Bank's risk appetite. 2. Senior management is involved, ensuring consistent risk management and control through its conduct, actions, and communications. Additionally, it will promote the risk culture, assessing its degree of implementation and ensuring that the profile remains within the levels defined in the Bank's risk appetite. 3. Independence of risk management and control functions. 4. An anticipatory and comprehensive approach to risk management and control across all businesses and types of risks. 5. Correct and complete information management that allows risks to be identified, evaluated, managed and communicated appropriately to the corresponding levels These principles, along with a series of interrelated tools and processes in its strategy, such as risk appetite, risk profile assessment, scenario analysis, and risk reporting framework, as well as annual budgeting processes, constitute a holistic control structure for the entire Bank. The Bank's risk classification enables effective risk management, control, and communication. Its corporate risk framework includes the following: • Credit risk: It is the risk of financial loss resulting from the default or deterioration of the credit quality of a client or counterparty for whom Banco Santander Chile has financed or with whom it has assumed a contractual obligation. • Market risks: These arise from holding financial instruments whose value may be affected by changes in market conditions; they generally include the following types of risk: - Foreign exchange risk: which arises as a result of fluctuations in the exchange rate between currencies. - Fair value risk due to interest rate fluctuations: which arises as a result of fluctuations in market interest rates. - Price risk: which arises as a result of changes in market prices, either due to factors specific to the instrument itself or due to factors that affect all instruments traded in the market. - Inflation risk: which arises as a result of changes in inflation rates in Chile, the effect of which would apply primarily to financial instruments denominated in UF. • Liquidity risk: It is the risk of not having the necessary liquid financial resources to meet obligations when they mature, or of obtaining them only at a high cost. • Operational risk: It is the risk of loss due to inadequate or failed internal processes, employees, and systems, or due to external events. This includes legal risk and conduct risk. • Capital risk: It is the risk that the Bank has insufficient capital in quantity and/or quality to meet the minimum requirements for operating as a bank, meeting market expectations regarding its creditworthiness, and supporting the growth of its business and any strategies that may arise in accordance with its strategic plan.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued Risk governance The Bank has a robust risk governance structure that pursues effective risk profile control, in accordance with the appetite defined by the Board of Directors and based on the distribution of roles among the three lines of defense and a solid committee structure. The Bank's three lines of defense model seeks to ensure effective risk management and control: First line: business lines and all other risk-generating functions constitute the first line of defense. These functions must ensure that the risks generated are aligned with the approved risk appetite and corresponding limits. Any unit that generates risk has primary responsibility for managing that risk. Second Line: the risks, compliance, and conduct functions. Their role is to independently oversee and challenge the risk management activities performed by the first line of defense. These functions ensure risk management in accordance with the appetite defined by the Board and promote a strong risk culture throughout the organization. Third Line: the Internal Audit function periodically assesses the appropriateness and effectiveness of policies, methodologies, and procedures for managing and controlling all risks. The risk, compliance, and internal audit functions enjoy an appropriate level of separation and independence and have direct access to the Board of Directors and its committees. The governance applied in the Bank must promote efficient governance structures that ensure the participation of all relevant functions. Governance must also be compatible with local-level functions and with coordinated management and supervision. The main objectives of risk governance are: → Enable effective and efficient risk decision-making. → Oversee risk control. → Ensure that risks are managed in accordance with the risk appetite defined by the Board. The governance structure must separate risk management and control, to achieve these objectives: → Governance reinforces the responsibility of the first line of defense in decision-making and ensures that all risk decisions have a formal approval process. → For the second line of defense, governance provides an overview of all risks, regardless of who manages or controls them. Risk government structure The risk governance structure meets legal and regulatory requirements, which is characterized by an efficient governance structure that ensures the participation of all relevant areas, promoting clear and effective decision-making and accountability. The responsibilities and membership of the most relevant committees within risk governance are: 1. Board of Directors: ultimately responsible for risk management and control. Its key responsibilities include approving the risk appetite and risk framework, and promoting a strong risk culture. To support the Board's management, there are five committees, which are established and amended according to the bank's needs. These committees report their activities to the Board periodically through meetings and subrogation schemes, statutes, formal minutes, and monitoring processes: the Directors and Audit Committee, the ALCO and Markets Committee, the Integral Risk Committee, the Appointments Committee, and the Compensation Committee. 2. Integral Risk Committee (IRC): is responsible for advising the Board of Directors on defining the risk appetite that business areas can assume, as well as overseeing the correct identification, measurement, and control of all risks that may affect the Bank. 3. Executive Risk Committee: responsible for risk management, in accordance with the powers delegated to it. This committee evaluates credit operations over a certain amount (operations of smaller amounts are evaluated by lower-level committees). 4. Risk Control Committee: responsible for risk control, determining whether businesses are managed in accordance with the risk appetite and providing a holistic view of all risks. This includes identifying and monitoring both current and emerging risks and their impact on the risk profile.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued 5. Global Compliance Committee: responsible for overseeing the management of the risks to which the Bank is exposed, including regulatory compliance risk, conduct risk, money laundering and terrorist financing risk, and reputational risk. 6. Analysis and Resolution Committee (CAR): responsible for defining and monitoring compliance with the policies, standards, and general and specific objectives regarding the prevention of money laundering and terrorist financing, in accordance with local laws and regulations, as well as those of the Santander Group Risk assessment and identification The Bank evaluates at least once a year all the types of risk to which it is exposed, allowing it to define the level to which it is exposed in each of them through a systematic and objective process. Also, through a formal process, it reviews the evolution of each risk by analyzing qualitative and quantitative variables. The results are presented and discussed monthly at the highest management and supervisory levels. In parallel, emerging risks are surveyed every six months, a process in which a large part of the organization participates. This process identifies the main potential risks that could jeopardize strategic planning from a holistic perspective, allowing for a prioritization of these risks based on an assessment of their impact on results/capital and the probability of occurrence. It is important to highlight that this process allows new concerns to be identified and made visible in order to contain them. Key Risk Management and Control Processes It is important to note that each of these key processes has demanding standards, which reflect international best practices. → Planning. Planning is the process by which business objectives are established. It must include the formulation of the types and levels of risk that the business is able and willing to assume to achieve those objectives. → Identification. Risk identification is an essential component for effective risk management and control. All employees are responsible for identifying the risks within their scope of work. → Assessment. Once identified, risks must be assessed. → Decision-making and execution. Decisions are necessary to manage the business risk profile within the limits approved in the planning phase and to achieve business objectives. Strategic decisions are also necessary to manage material and emerging risks. → Monitoring plan performance. Regular monitoring of business performance and comparing it with approved plans is an essential daily activity. → Measures to correct deviations from the plan and information processes If the monitoring activity reveals deviations, or probable deviations, from performance beyond the approved ranges or alert levels, mitigation measures should be considered to return performance to acceptable levels. CREDIT RISK Credit risk is the risk of financial loss resulting from the default or deterioration of the credit quality of a client or counterparty for whom the Bank has financed or with whom it has assumed a contractual obligation. It is our most significant risk, both in terms of exposure and capital consumption. Credit risk management The Bank's credit risk identification, analysis, decision-making, and control processes are based on a complete view of the credit risk cycle, including the transaction, the client, and the portfolio. Credit risk identification enables active management and effective portfolio control. We identify and classify external and internal risks in each business and adopt corrective and mitigating measures when necessary, through the following processes: 1. Planning: Planning allows us to establish business objectives and define specific action plans in line with our risk appetite statement. Commercial strategic plans are a management and control tool defined by the business and risk areas for our credit portfolios. They determine commercial strategies, risk policies, resources, and infrastructure, ensuring a holistic view of the portfolios.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued 2. Risk Assessment and Credit Rating Process: Credit approval criteria are generally based on a borrower's ability to meet his or her financial obligations. To determine this ability, we analyze the borrower's net cash flow or business income. Our credit quality assessment models are based on rating engines, which vary for each of our segments, which we monitor and compare to adjust the decisions and ratings we assign. 3. Scenario analysis: This allows for determining potential risks in credit portfolios, providing a better understanding of their behavior under different macroeconomic conditions, as well as anticipating and implementing management strategies to avoid future deviations from established plans and objectives. 4. Monitoring: Holistic monitoring of all clients facilitates monitoring of credit quality and early detection of impacts on risk evolution. Regular monitoring of business performance and its comparison with pre-established plans are essential in credit risk management. Our monitoring function uses a system that helps establish monitoring levels, policies, and specific actions for each client. 5. Credit risk mitigation techniques: Credit approval criteria are based on determining the borrowers' ability to pay to meet their financial obligations, without relying on guarantors or pledged assets as collateral. These are always considered a second source of recovery in the event of the failure of the first, and are defined as a reinforcing measure added to a credit transaction in order to mitigate the loss in the event of default. 6. Recovery management: Recovery management defines a strategy based on the economic environment, business model, and other specificities of local recovery. Effective and efficient recovery management requires segmenting our clients based on their characteristics and using new digital channels that support sustainable value creation. The Board of Directors has delegated responsibility for credit risk management to the IRC and the Bank's risk departments, whose roles are summarized below: • Formulation of credit policies, in consultation with the business units, covering collateral requirements, credit evaluation, risk rating, and reporting, documentation, and legal procedures in compliance with the Bank's regulatory, legal, and internal requirements. • Establishing the authorization structure for the approval and renewal of credit applications. The Bank structures credit risk levels by placing limits on the concentration of that risk in terms of individual debtors, debtor groups, industry segments, and countries. • Authorizations are assigned to the respective business unit officers (commercial, consumer, SME) for ongoing monitoring by Management. These limits are also reviewed periodically. Branch-level risk assessment teams regularly interact with clients; however, for large transactions, the parent company's risk teams, including the CIR, work directly with clients to assess credit risks and prepare credit applications. • Limit exposure concentrations to clients and counterparties, by geographic area, industry (for receivables or loans), and by issuer, credit rating, and liquidity (for investments). • Develop and maintain the Bank's risk classification, classifying risks according to the degree of exposure to financial loss faced by the respective financial instruments and focusing risk management specifically on the associated risks. • Review and assess credit risk. The risk divisions are largely independent of the Bank's commercial division and assess all credit risks in excess of designated limits prior to approving loans to clients or prior to the acquisition of specific investments. Credit renewals and reviews are subject to similar processes. Risk assessment teams interact regularly with our clients. For larger transactions, risk teams work directly with clients to assess credit risks and prepare credit applications. Credit approval committees, which include risk and commercial staff, must ensure that each applicant meets the appropriate qualitative and quantitative parameters. The powers of each committee are defined by the Bank's Board of Directors.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued When preparing a credit application for a corporate client whose loans are approved on an individual basis, the Bank verifies several parameters such as debt service capacity (usually including projected cash flows), the client's financial history, and/or projections for the economic sector in which it operates. The risk division is closely involved in this process and prepares the client's credit application. All applications contain an analysis of the client's strengths and weaknesses, a rating, and a recommendation. Credit limits are not determined based on the client's outstanding balances, but rather on the direct and indirect credit risk of the financial group. For example, a corporation would be assessed along with its subsidiaries and affiliates. Consumer loans are evaluated and approved by their respective risk divisions (individuals, SMEs). The evaluation process is based on an evaluation system known as Garra (Banco Santander-Chile), an in-house automated process based on a scoring system that includes the credit risk policies implemented by the Bank's Board of Directors. The loan application process is based on the collection of information to determine the client's financial situation and repayment capacity. The parameters used to evaluate the applicant's credit risk include several variables such as income level, length of current employment, debt indebtedness, and credit agency reports. In the case of investments in debt instruments, the Bank assesses the probability of default of the issuers or counterparties using internal and external assessments, such as those by risk assessors independent of the Bank. Furthermore, the Bank adheres to a strict and conservative policy that ensures that the issuers of its investments and counterparties in derivative transactions are of the highest reputation. Additionally, the Bank operates with several instruments that involve exposure to credit risk, which are not reflected in the Interim Consolidated Statements of Financial Position, such as, for example: guarantees and warranties, documentary letters of credit, guarantee notes and commitments to grant credits.. Guarantees and warranties represent an irrevocable payment obligation. If a guaranteed client fails to meet their obligations to third parties guaranteed by the Bank, the Bank will make the corresponding payments. Therefore, these transactions represent the same credit risk exposure as a regular loan. Documentary letters of credit are commitments documented by the Bank on behalf of the client. These commitments are secured by the traded goods they relate to and have a lower risk than direct borrowing. Guarantee bonds are contingent commitments that become effective only if the client fails to perform the work agreed upon with a third party, guaranteed by them. When it comes to credit commitments, the Bank is potentially exposed to losses equal to the total undrawn commitment. However, the probable loss is less than the total undrawn commitment. The Bank monitors the maturity period of credit lines because long- term commitments generally carry a higher credit risk than short-term commitments. Additional provisions Under FMC regulations, banks are allowed to establish provisions above the limits described above, in order to protect themselves from the risk of unpredictable economic fluctuations that could affect the macroeconomic environment or the situation of a specific economic sector. These provisions, in accordance with Chapter B-1, Section 9 of the FMC's CASB, will be reported as liabilities. The Bank's Board of Directors approved the constitution of additional voluntary provisions, which amount to Ch$156,098 million and Ch$179,098 million as of June 30, 2026, and December 31, 2025, respectively. Maximum exposure to credit risk For financial assets recognized in the Interim Consolidated Statements of Financial Position, the credit risk exposure is equal to their carrying amount. For financial guarantees granted, the maximum credit risk exposure is the maximum amount the Bank would have to pay if the guarantee were enforced.

Meanwhile, Loans and receivables from customers and debt instruments measured at fair value through other comprehensive income, and debt instruments measured at amortized cost, their impairment is measured in accordance with Chapter 5.5 of IFRS 9. Impairment requirements do not apply to debt instruments measured at fair value through profit or loss. In the case of derivatives, the adjustment that reflects the counterparty credit risk (CVA) is included in their fair value. CVA is calculated considering the potential exposure to each counterparty in future periods. The methodology established for determining provisions for loans (Interbank and Loans and receivables from customers) and contingent loans is set out in Note 2 of accounting principles, letter q). The methodology used to calculate provisions for Loans and accounts receivable from customers and debt instruments measured at fair value through other comprehensive income, and debt instruments measured at amortized cost, is described in Note 2, letter r). Information related to the concentration of credit risk is provided in Note 13, letters k, m and n. For derivative instruments, as of June 30, 2026, the Bank's foreign exposure, including counterparty risk in the derivatives portfolio, was US$1.23 million or 2% of total foreign exposure to countries with a rating above category 1, as shown in the table below. In the table below, as of June 30, 2026, exposure to derivative instruments is calculated using the credit equivalent risk, which is equal to the net replacement cost plus the maximum potential exposure, taking into account cash collateral that mitigates the exposure. Additionally, further details are provided below regarding our exposure to those countries with a rating above 1.

Recognition and measurement of credit risk provisions The Bank segments loans and contingent loans by borrower type and loan type, to a level appropriate for the application of the models. The provisions required to cover loans, debt instruments, and contingent loan exposure are calculated and recorded monthly, based on the valuation models used and the type of transaction. Provisions related to loans and receivables from customers/debt instruments measured at amortized cost and loans and receivables from customers at fair value through other comprehensive income are accounted as valuation accounts into respective items, and reporting net in the Consolidated Statement of Financial Position. Additional provisions and contingent loans provisions are reported as liabilities, in accordance with the FMC's directions. Provisions for financial assets at fair value through other comprehensive income are presented in Note No. 11, provisions for financial assets at amortized cost are presented in Note No. 13, and special provisions for credit risk (contingent loans, country risk, additional provisions) are presented in Note No. 26.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued Individual / Group assessment Group assessments are suitable for addressing a large number of transactions with low individual amounts, involving individuals or small businesses. The Bank groups borrowers with similar credit risk characteristics, assigning each group a specific probability of default and a recovery percentage based on a substantiated historical analysis. For this purposes, the Bank implemented the standard model for housing and commercial loans, and an internal model for consumer loans. IFRS 9 establishes the recognition of lifetime expected credit losses when significant increases in credit risk are observed since initial recognition. In that context, a collective assessment may be required, as the increase in credit risk may become more evident before the financial assets becomes nonperforming, depending on the nature and information available for the financial assets. This is always based on the assumption that the information is available without cost or effort. Impaired loans The impaired loan portfolio includes defaulted loans (C1 to C6), plus loans B3 and B4, in the case of individual assessments. As of June 30, 2026 and December 31, 2025, the impaired loan portfolio amounts to Ch$3,120,504 million and Ch$2,789,706 million, respectively. IFRS 9 defines an asset as credit-impaired when one or more events have occurred that have a negative impact on estimated future cash flows, evidenced by the issuer's financial difficulties, default, bankruptcy or financial reorganization, disappearance from an active market, among others. Debt instruments and loans and receivables from customers measured at fair value through other comprehensive income are not credit impaired. Write-offs Write-offs must be made when contractual rights to cash flows expire. A write-off constitutes a derecognition event from balance sheet and include the unpaid portion in the case of installment loans (no partial write-off). Additional circumstances could lead the write-off of a loan: when the Bank concludes that it will not obtain any cash flows, or there is no enforceable title, when the collection demand actions expire, or when the deadlines defined by the FMC are reached (see Note 2, letter q). As of June 30, 2026 and December 31, 2025, the written-off loans amounted to Ch$350,942 million and Ch$383,555 million, respectively. IFRS 9 establishes that a write-off occurs when there is no reasonable expectation of recovering the contractual cash flows in whole or in part. A write-off constitutes a derecognition. Debt instruments and loans and receivables from customers measured at fair value through other comprehensive income do not include any written-off instruments/transactions. Reconciliation of loans The reconciliation between the opening and closing balances of provisions for financial assets measured at amortized cost and for contingent loans are presented in Note 13 letters f, g, h, i and j.

When a debtor experiences financial difficulties or a significant deterioration in its payment capacity, and there are reasonable doubts about the full recovery of principal and interest under the contractual terms, the client is classified in the substandard portfolio. A client will be classified in the defaulted portfolio if the probability of credit recovery is considered remote, as it payment capacity is deteriorated or nonexistent.

Based on this, guarantees are a necessary but insufficient instrument in granting loans; therefore, the Bank's risk acceptance requires verification of other variables or parameters, such the payment capacity or generation of resources to mitigate the risk incurred. The procedures for management and valuation of guarantees are included in the internal risk management policy. These policies establish the basic principles for credit risk management, and the management over guarantees received in operations with clients. In this regard, the risk management model includes assessing the existence of appropriate and sufficient guarantees that allow credit recovery when the debtor's circumstances prevent him from meeting his obligations. The collateral valuation procedures are consistent with market best practices, which involve the use of appraisals for real estate guarantees, market value for stock market securities, the value of investment fund shares, etc. All received guarantees must be properly instrumented and appropriately registered, as well as have the approval of the Bank's legal divisions. The Bank also has rating tools that allow ranking the credit quality of transactions or clients. The Bank historical databases, store internally generated information, that allow to study the probability of variation. Rating tools consider client segment analyzed (commercial, consumer, SME, etc.).

When the Bank is required to take possession of or foreclose on a property, it is recorded as an “Asset received or awarded in lieu of payment,” and the loan and its allowance are derecognized. The asset received is recorded at the lower of its carrying amount and its fair value (appraisal) less costs to sell, in accordance with IFRS 5, and is classified as held for sale.

These can be in cash or financial instruments, and reduce the counterparty's credit risk. These guarantees are monitored periodically (usually daily). Based on this, the net balance per counterparty is determined, and based on agreed-upon parameters, it is determined whether a collateral should be deposited or collected. Credit limits for borrowers related to the Bank’s ownership or management In accordance with Article 84 No. 2 of the General Banking Law and UCBR 12-4, the total amount of credit granted to a group of related parties may not exceed 5% of the Bank’s regulatory capital. This limit increases to 25 percent if the portion exceeding 5 percent consists of loans secured by collateral. In no case may the total of such credits granted by a bank exceed the amount of its regulatory capital. These loans may not be granted under more favorable conditions in terms of maturity, interest rates, or collateral than those offered to third parties in similar transactions. A relationship with the Bank occurs when they have a direct, indirect, or third-party participation in the Bank's ownership, participate in the management, or are presumed to exist until sufficient evidence is presented to eliminate that presumption. It will be understood that all natural and legal persons who can exert significant and permanent influence on the decisions of the other form the same group of persons related to the Bank, where there is a presumption that the credits granted to one person will be used for the benefit of another or a well-founded presumption that the persons maintain a relationship and form a unit of economic interest. Companies related to a Bank include subsidiaries, support companies, and affiliates. Legal guarantees include guarantees on tangible personal or real property, real estate, or any other property that can legitimately be accepted as collateral. On June 30, 2026, and December 31, 2025, the credit limit for debtors related to the ownership or management of the Bank according to article 84 No. 2 of the GBL and Chapter 12-4 of the UCBR are as follows: As of June 30, 2026 As of December 31, 2025 % Ch$mn % Ch$mn Overall limit to related parties 7 % 509,551 7 % 487,292 Regulatory capital 7,279,306 7,047,321 Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 206
NOTE 47 - RISK MANAGEMENT AND REPORTING, continued MARKET RISK Market risk arises as a result of market activity involving financial instruments whose value may be affected by fluctuations in market conditions and reflected in assets/liabilities changes and financial risk factors. The objective of market risk management is to manage and control exposure to market risk within acceptable parameters. There are four major risk factors that affect market prices: interest rates, exchange rates, price, and inflation. • Interest Rate Risk: the exposure to losses arising from adverse changes in market interest rates that affect the value of instruments, contracts and other transactions recorded on the balance sheet. • Exchange risk is the sensitivity to losses arising from adverse changes in the value of the exchange rates of foreign currencies, including gold, in which the instruments, contracts and other transactions recorded on the balance sheet are denominated. • Inflation risk is the exposure to losses arising from adverse changes in the units or indices of readjustment defined in national currency. The instruments, contracts, and other transactions are denominated on the balance sheet. • Price risk is generated by the volatility of rates or prices of assets or liabilities. Prepayment risk arises when, based on price movements, holders can alter the future cash flows of these assets or liabilities, leading to balance sheet mismatches that pose additional challenges to market risk management. Market risk management The measurement and control of market risks are the responsibility of Market Risk Area, which is part of the Risk Division. The appropriate committees approve the limits, with responsibility resting mainly with the ALCO. The Integral Risk Committee also reviews the principal market risks. The Financial and Capital Management areas, as part of the Financial Vice-Presidency, have the following functions, which are supervised and controlled by the ALCO and Risk Division: i. To optimize the cost of liabilities and seek the most efficient financing strategies, including issuing bonds and bank facilities. ii. Management of short- and long-term regulatory liquidity limits. iii. Inflation risk management and exposure. iv. To manage local and foreign currency rate risk. v. Capital adequacy and requirements. Rate sensitivity is measured primarily using an analysis that quantifies the impact on earnings and the balance sheet of parallel movements in the real and nominal interest rate curve in Pesos and US dollars. The Bank's internal management for measuring market risk is mainly based on analyzing the management of the following three components: • Trading portfolio. • Local currency financial management portfolio. • Foreign currency financial management portfolio. The Treasury manages the Bank's trading portfolios and ensures they remain within the loss limits determined, calculated and estimated by the Market Risk Area. The trading portfolio (measured at fair value through profit or loss) consists mainly of those investments measured at fair value, free of any restriction on their immediate sale and which are often bought and sold by the Bank to sell them in the short term to benefit from short-term price movements. The Financial Management's portfolios (measured at fair value through other comprehensive income) include all financial investments not considered in the trading portfolio.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued The roles that concern the trading portfolio comprise the following: i. applying Value-at-Risk (VaR) techniques to measure interest rate risk, ii. adjusting trading portfolios to market and the measurement of daily profit and loss from trading activities, iii. comparing the actual VAR with the established limits, iv. establishing loss control procedures for losses above predetermined limits, and v. providing information on trading activities to the ALCO, other members of the Bank's management, and the Global Risk Department. The functions regarding financial management portfolios entail the following: i. Applying sensitivity simulations (as explained below) to measure the interest rate risk of local currency activities and the potential loss predicted by these simulations and ii. Providing the respective daily reports to the ALCO, other members of the Bank's Management, and the Global Risk Department. Market risk – Trading portfolio The Bank applies VaR methodologies to measure exchange rate risk and sensitivity to interest rates of the trading portfolio. The Bank has a consolidated commercial position comprised of fixed income investments and foreign currency trading. This portfolio is essentially composed of bonds from the Central Bank of Chile, mortgage bonds and low risk locally issued corporate bonds. At the end of the year, the trading portfolio did not contain investments in equity. For the Bank, the VaR estimate is carried out using a historical simulation methodology, which consists of observing the behavior of the losses and gains that would have occurred with the current portfolio using the market conditions of a predetermined historical period. From that information, the maximum loss is inferred with a certain level of confidence. The methodology has the advantage of accurately reflecting the historical distribution of market variables and of not requiring any specific probability distribution assumptions. All VaR measures are intended to determine the distribution function for the change in the value of a given portfolio, and once this distribution is known, to calculate the percentile related to the necessary confidence level, which will be equal to the value at risk in virtue of those parameters. As calculated by the Bank, the VaR is an estimate of the maximum expected loss of the market value of a given portfolio over a 1-day horizon at a confidence level of 99.00%. It is the maximum one-day loss that the Bank could expect to suffer on a given portfolio with the 99.00% confidence level. In other words, it is the loss that the Bank would expect to exceed only 1.0% of the time. VaR provides a single estimate of market risk that is not comparable from one market risk to another. Returns are calculated using a time window of 2 years or at least 520 data points obtained from the VaR calculation reference date backward in time. The Bank does not calculate three separate VaRs. Instead, a single VaR is calculated for the entire trading portfolio, further segregated by risk type. The VaR program performs a historical simulation and calculates a Profit and Loss (P&L) statement for 520 data points (days) for each risk factor (fixed income, foreign exchange and equities). Then, the P&L of each risk factor is added together, and a consolidated VaR is calculated with 520 data points or days of data. Simultaneously, the VaR is calculated for each risk factor based on the individual P&L calculated for each factor. Moreover, a weighted VaR is calculated similarly, as described above, but gives a higher weighting to the most recent 30 data points. As a result, the higher of the two VaRs is reported. The Bank uses VaR estimates to warn if statistically estimated losses in the trading portfolio exceed prudent levels and, therefore, certain predetermined limits are in place. Limitations of the VaR model In applying this methodology for calculation, no assumptions are made about the distribution probability of changes in the risk factors; instead, the historically observed changes are used to generate scenarios for the risk factors under which each portfolio item will be valued. The definition of a valuation function fj (xi) for each instrument j is necessary, preferably the same as the one used to calculate the market value and daily position results. This valuation function shall be applied to generate simulated prices for all instruments in each scenario.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued Furthermore, the VaR methodology should be interpreted considering the following limitations: • Market rate and price changes may not consist in independent and identically distributed random variables, nor may they have a normal distribution. The normal distribution assumption, in particular, may underestimate the probability of extreme market movements. • The historical data used by the Bank may not provide the best estimate of future joint distribution of changes in risk factors. Any modification of the data may be inappropriate. In particular, the use of historical data may fail to capture the risk of possible extreme and adverse market fluctuations regardless of the time frame used; • A 1-day time horizon may not fully capture those market risk positions that cannot be liquidated or hedged within one day. It would not be possible to liquidate or hedge all positions in one day; • The VaR is calculated at the end of negotiations, but trading positions may change substantially during the trading day; • The use of a 99% confidence level does not consider or make any representation about losses that may occur beyond this confidence level, and • The VaR model does not capture all the complex effects of risk factors on the value of positions or portfolios and, therefore, may underestimate potential losses. As of June 30, 2026, and December 31, 2025, the Bank did not exceed the VaR limits of the trading portfolio’s, considering the three components: fixed-income, equity, and foreign currency investments. The Bank performs back-testing daily and generally finds that trading losses exceed the estimated VaR almost once every 100 trading days. At the same time, a limit was set on the maximum acceptable VaR on the trading portfolio. As of June 30, 2026, and December 31, 2025, the Bank has remained within its VaR threshold, even in instances where the actual VaR exceeded the estimated VaR. The high, low and average levels for each component and each year were as follows: VAR As of June 30, 2026 2025 US$mn US$mn Consolidated High 2.89 3.31 Low 0.88 1.35 Average 1.79 2.03 Fixed income investments High 2.50 1.51 Low 0.85 0.92 Average 1.67 1.21 Variable income investments High – – Low – – Average – – Foreign currency investments High 1.77 2.75 Low 0.06 0.75 Average 0.47 1.53 Market risk – Local and foreign financial management The Bank's financial management portfolio includes most of the Bank's assets and non-trading liabilities, including the loan portfolio. The Bank's commercial strategies (structural risk) heavily influence these portfolios' investment and funding decisions.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued The Bank uses sensitivity analysis to measure the market risk of local and foreign currency (not included in the trading portfolio). The Bank conducts a scenario simulation, which is calculated as the difference between the present value of the flows in the chosen scenario (curve with a parallel movement of 100 bps in all segments) and their value in the baseline scenario (current market). All items in local currency indexed to inflation (UF) are adjusted by a sensitivity factor of 0.57, representing a yield curve shift by 57 basis points in real rates and 100 basis points in nominal rates. The same scenario is conducted for net foreign currency positions and interest rates in US dollars. The Bank has also set limits on the maximum loss these interest rate movements can have on budgeted capital and net interest income for the year. To determine the consolidated limit, the foreign currency limit is added to the local currency limit for both the net financial loss limit and the capital loss and reserves limit using the following formula: Bounded limit = square root of a2 + b2 + 2ab, in which: a: limit in national currency. b: limit in foreign currency. Since it is assumed that the correlation is 0. 2ab = 0. Limitations of sensitivity models The most important assumption is using a change of 100 basis points in the yield curve (57 basis points for real rates). The Bank uses a change of 100 basis points as sudden changes of this magnitude are considered realistic. In addition, the Global Risk Department has also established comparable country limits to compare, monitor and consolidate market risk by country in a realistic and orderly manner. Furthermore, the methodology of sensitivity simulations should be interpreted considering the following limitations: • The scenario simulation assumes that the volumes remain on the Bank's Interim Consolidated Statements of Financial Position and are always rolled over at maturity, omitting the fact that certain credit risk considerations and prepayments may affect the maturity of certain items. • This model assumes an equal change across the entire yield curve and does not consider different movements for different maturities. • The model does not consider the sensitivity of volumes resulting from changes in interest rates. Limits on budgeted finance income losses are calculated based on expected finance income for the year that cannot be obtained. This means the actual percentage of finance income at risk could be higher than expected.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued Inflation risk The Bank's assets and liabilities are indexed according to the Unidad de Fomento (UF) variation. The Bank has, in general, more assets than liabilities in UF. Therefore, moderate rises in inflation have a positive effect on interest income from inflation adjustments, while a fall in the UF value negatively impacts the Bank's net interest margin. To manage this risk, the Assets and Liabilities Committee limits the difference between UF-denominated assets and liabilities, which may not exceed 30% of the Bank's interest-earning assets. Financial Management manages this mismatch on a day-to-day basis, and the limits are calculated and monitored by the Market Risk Division. Market Risk items and their measurement Market Risk Exposure is measured and monitored using the difference between the foreign currency asset and liability balances (net position) and the cash flows payable (associated with liability items) and cash flows receivable (associated with asset items) in the Trading and Banking Books for a given period. Foreign currency items and term mismatches are exposed to different adjustment factors, sensitivities, and rate changes. The Board of Directors of Banco Santander Chile presented and approved the Market Risk Exposure Policy on a Standardized Basis. The following risks will determine Market Risk Exposure: • Interest Rate Risk. • Foreign exchange Risk. • Readjustment (Inflation) Risk. • Currency Options Risk. The following illustrates the market risk exposure according to the guidelines of the FMC and the Central Bank of Chile. The maximum exposure to long-term interest rate risk is 35% of regulatory capital and is approved by the Board of Directors. The maximum exposure to short-term interest rate risk is 55% of total net interest income and readjustment income plus interest rate sensitive fees: As of June 30, 2026 As of December 31, 2025 Ch$mn Ch$mn Market risk of the trading book Exposure to interest rate risk 617,685 565,138 Exposure to foreign currency risk 3,897 4,484 Exposure to foreign currency options 1,055 1,896 Total exposure of the trading portfolio 622,637 571,518 10% of Risk Weighted Assets (RWA) 778,291 714,397 Subtotal 1,400,928 1,285,915 Limit = Regulatory capital 7,279,307 7,047,322 Available margin 5,878,379 5,761,407 Short-term exposure to interest rate risk 107,513 101,913 Exposure to readjustment (inflation) risk 216,262 153,766 Short-term risk of the banking book 323,775 255,679 Limit = 55% of total net interest income + fees sensitive to interest rates 1,046,825 1,008,348 Available margin 723,050 752,669 Long-term exposure to interest rate risk 787,719 728,870 Limit = 35% of regulatory capital 2,547,757 2,466,563 Available margin 1,760,038 1,737,693 Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 211
NOTE 47 - RISK MANAGEMENT AND REPORTING, continued To fulfill its functions, the Integral Risk Committee works directly with the Bank's control and risk departments whose joint objectives include: • Evaluate those risks that, due to their size, could compromise the Bank's solvency, or that potentially present significant operational or reputational risks; • Ensure that the Bank is equipped with the means, systems, structures and resources in accordance with the best practices that allow the implementation of the risk management strategy; • Ensure the integration, control and management of all the Bank's risks; • Execute the application throughout the Bank and its businesses of homogeneous risk principles, policies and metrics; • Develop and implement a risk management model in the Bank, so that risk exposure is adequately integrated into the different decision-making processes; • Identify risk concentrations and mitigation alternatives, monitor the macroeconomic and competitive environment, quantifying sensitivities, and the foreseeable impact of different scenarios on risk positioning; and • Manage the structural risks of liquidity, interest rates and exchange rates, as well as the Bank's own funding base. To meet the aforementioned objectives, the Bank (Management and ALCO) carries out several activities related to risk management, which include: calculating the risk exposures of the different portfolios and/or investments, considering mitigating factors (guarantees, netting , collaterals, etc.); calculate the probabilities of expected loss for each portfolio and/or investments; assign loss factors to new operations (rating and scoring); measure the risk values of portfolios and/or investments based on different scenarios through historical simulations; establish limits on potential losses based on the different risks incurred; determine the possible impacts of structural risks on the Bank's Interim Consolidated Statements of Financial Position; set the limits and alerts that guarantee the Bank's liquidity; and identify and quantify operational risks by business lines and thus facilitate their mitigation through corrective actions. LIQUIDITY RISK This refers to the possibility that an entity may not be able to meet its payment commitments or may have to resort to raising funds on burdensome terms. Liquidity risk management The Bank's approach to liquidity management is to ensure, to the extent possible, that it always has sufficient resources to meet its obligations as they fall due under normal circumstances and stress conditions without incurring unacceptable losses or risking damage to the Bank's reputation. The Financial Management area manages liquidity risk by using a portfolio of liquid assets to ensure that the Bank always maintains sufficient liquidity to cover short-term fluctuations and long-term funding while complying with internal liquidity regulatory requirements. The Financial Management area receives information from all business units on the liquidity profile of their financial assets and liabilities, as well as a breakdown of other projected cash flows from future business. Based on this information, the area maintains a portfolio of short-term liquid assets, consisting mainly of liquid investments, loans and advances to other banks, to ensure that the Bank has sufficient liquidity. The liquidity needs of the business units are covered by short-term transfers from Financial Management to cover short-term fluctuations and long-term funding to meet all structural liquidity needs. Accordingly, the Board sets limits on a minimum portion of maturing funds available to meet such payments and on a minimum level of interbank operations and other lending facilities that should be available to cover unexpected demands for withdrawals of liquidity. This is reviewed periodically by the ALCO whose functions include monitoring the strategies to manage liquidity risk. Setting these limits is conceived as a dynamic process that responds to the level of risk appetite deemed acceptable by the Bank and its entities. The system of limits is sufficiently robust to be aware at all times of the level of exposure that each institution is incurring in, in terms of liquidity risks. Besides the limits, the Bank includes alert indicators by the concentration of counterparties, type of products, and maturities in its management to diversify the funding sources and their maturity structure. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 212
NOTE 47 - RISK MANAGEMENT AND REPORTING, continued The Bank monitors its liquidity position daily, determining future inflows and outflows. Furthermore, stress tests are performed at the end of each month, using a variety of scenarios covering both normal market conditions and market fluctuation (stress) conditions. The Bank has a structure of internal liquidity limits that Financial Management and the Treasury must respect at all times. Market Risk Management calculates and monitors the consumption of internal limits, verifies compliance with them and communicates their status to senior management and the Board of Directors. At the beginning of each calendar year, these limits are proposed by Market Risk Management, approved locally at the ALCO and then ratified at the highest Board level. Liquidity limits and early warning indicators, and internally defined management measures can be differentiated into the following three groups: • Limits associated with concentration and mismatches of cash flows and liquidity of the Bank's operations. • Liquidity Management Tools, known as Structural Liquidity or Funding Tables, are used to determine the Bank's structural liquidity position. It also permits the Bank to actively manage its structural liquidity, since this is an essential mechanism to ensure a permanent funding of assets under optimal conditions. • Early warning indicators are linked with concentration risks and are used as tools for detecting and anticipating potential liquidity stress situations and, if necessary, activating the Liquidity Contingency Plan. The Market Risk Area establishes and updates the Bank’s Liquidity Management Policy (LMP). Reviews and possible updates are conducted once a year. Nevertheless, it may be updated at the request of any areas affected by the LMP that have identified the need for modification. The Board approves the contents of the LMP. The Market Risk Area provides all the necessary tools for the statistical analysis required by local liquidity regulations. It also assesses, at least once a year, whether the models are still valid. The Board of Directors must approve the conclusions of this analysis. In periods of normal liquidity, Financial Management applies policies and makes arrangements to keep the Bank within internal and regulatory limits. If a crisis has been identified, even at its mildest level, the Liquidity Crisis Committee applies the necessary policies to deal with potential liquidity shortfalls or restrictions, creates contingency plans to manage emergencies quickly, and reports such situations to senior management and the respective committees. Liquidity risk measurement and control 1. Maturity mismatches subject to regulatory limits The Regulatory Liquidity Ratio measures and limits the mismatches of net income flows relative to capital. Under current regulations, the 30-day mismatch cannot exceed the Bank's core capital for both domestic and foreign currency by one time, and the 90-day mismatch cannot exceed it by two times. 2. Monitoring indicators and liquidity ratios subject to regulatory limits An important component of liquidity risk management is High-Quality Liquid Assets (HQLA). These are balance sheet assets, mainly consisting of financial investments that are not pledged as collateral, have low credit risk, and have a deep secondary market. According to Basel III standards, these assets are divided into three tiers, with Level 1 assets being the most liquid and Level 3 the least liquid. Level 1 assets are mostly composed of bonds from the Republic of Chile, the Central Bank of Chile, and the United States Treasury. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 213

Liquidity Coverage Ratio (LCR) The Liquidity Coverage Ratio (LCR) measures liquid assets over 30-day net cash outflows. It is used by banks globally as part of the Basel III standards. Chilean banks were required, starting in 2019, to meet a minimum level of 60%, which was to gradually increase to 100% by 2022. For the 2025 fiscal year and onward, a minimum level of 100% was mandated. The objective of the LCR is to promote the short-term resilience of banks' liquidity risk profiles. To this end, the LCR ensures banks have an adequate pool of unencumbered High-Quality Liquid Assets, which can be easily and immediately converted into cash in the private markets to cover short-term liquidity needs. Liquidity coverage ratio As of June 30, 2026 As of December 31, 2025 % % LCR 177 188 Banco Santander-Chile's LCR indicator was above the minimum required. This reflects the conservative liquidity policies imposed by the Board of Directors through the Assets and Liabilities Committee. 4. Net Stable Funding Ratio (NSFR) This indicator is required by Basel III and provides a sustainable maturity structure of assets and liabilities so that banks maintain a stable funding profile concerning their activities. The Central Bank of Chile and the FMC established a minimum NSFR level of 60% for 2022, gradually increasing to 100% by 2026. For 2026, the minimum required level is 100%. Net stable funding ratio As of June 30, 2026 As of December 31, 2025 % % NSFR 118 115 5. Information on liquidity position per the requirements of the Central Bank of Chile i.Maturity mismatches The Central Bank of Chile published on March 8, 2022, Rules on the Management and Measurement of the Liquidity Position of Banks, which modernized liquidity regulation, aligning the published regulatory requirements of the FMC to Basel III standards. According to the Central Bank, the liquidity position is measured and monitored through the difference between cash flows payable, which are associated with liability and expense account items, and cash flows receivable, which concern asset and income account items, for a given period or time frame, referred to as the maturity mismatch. The liquidity policy on an Adjusted Basis was presented and approved by the Board of Directors of Banco Santander-Chile. Maturity mismatch calculations are performed separately for domestic and foreign currencies.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued As of June 30, 2026, and December 31, 2025, the Central Bank required the Bank to maintain a technical reserve of Ch$0 for both periods. The volume and composition of liquid assets are presented in item 2 above. The liquidity coverage ratio is presented in item 3 above. 6. Maturity analysis of financial liabilities The remaining contractual maturities of financial liabilities are provided in Note 45. The liquidity management inherent in derivative and non-derivative financial liabilities is managed through various levers that enable this risk to be kept in line with the profile defined by the Bank while at the same time making efficient use of available liquidity. To this end, a high level of liquid assets is maintained, and the level of expected short-term income and expenditure is monitored daily, thus avoiding high concentrations of maturities. On the other hand, a very diversified funding matrix is maintained, both across product types and customer types. OPERATIONAL RISK Operational risk is defined as the risk of loss due to defects or failures of internal processes, employees and systems or external events. It covers risk categories such as operational incidents, cloud computing, cyber security, business continuity, and outsourced services, both and strategic and non-strategic. Operational risk is generated in all business and support areas and is inherent to all products, activities, processes and systems. For this reason, all employees are responsible for managing and controlling the operational risks generated by their activities. Our operational risk control and management model is based on a continuous process of identifying, assessing and mitigating risk sources, whether or not they have materialized, ensuring that risk management priorities are properly established. Operational risk management The operational risk model regulates the necessary elements for adequate management and control of operational risk, aligned with compliance with advanced regulatory standards and best management practices, and includes the following phases: • strategy and planning; • identification, assessment and monitoring of risks and internal controls; • implementation and monitoring of mitigation measures; • availability of information, adequate reporting and escalation of relevant issues. The main operational risk tools used are: • Internal events database. Recording operational risk events with financial impact (all losses are recorded, regardless of their amount) or non-financial impact (such as the regulatory impact on customers and/or services). This information: - allows root-cause analysis; - raises awareness of risks; - enables the escalation of relevant operational risk events to the senior management of the Risk Division with maximum immediacy; - facilitates regulatory reporting; • Self-assessment of operational risks and controls. A qualitative process that assesses the main operational risks related to each function, the state of the control environment and their assignment to the different functions within the Bank, using the judgment and experience of a panel of experts from each function. Banco Santander-Chile and Affiliates NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS As of June 30, 2026, and 2025, and as of December 31, 2025 Interim Consolidated Financial Statements June 2026 / Banco Santander-Chile 216
NOTE 47 - RISK MANAGEMENT AND REPORTING, continued The objective is to identify and assess material operational risks that could prevent business or support units from achieving their objectives. Once the risks and the internal controls that mitigate them have been assessed, mitigating measures are identified if risk levels are above tolerable. This process integrates specific operational risk reviews that allow for comprehensive and widespread identification of risks, especially technological risks, fraud, supplier risks and factors that could lead to other operational risks and specific regulatory non- compliance. • External events database. This involves quantitative and qualitative information of external operational risk events. The database allows for a detailed and structured analysis of relevant events in the sector, comparing the loss profile and the proper preparation of self-assessment exercises and scenario analysis. • Analysis of operational risk scenarios. Its objective is to identify events with an extremely low probability of occurrence that could generate significant losses for the Bank and establish appropriate mitigation measures through the assessment and expert opinion of the business lines and risk managers. • A statement establishing the Bank's commitment to controlling and limiting non-financial risk events that lead to or could lead to financial losses; fraud events; operational and technological incidents; legal and regulatory breaches; conduct issues, or reputational damage. Although a certain volume of losses is expected, unexpected high-severity losses due to a failure of controls are not acceptable. • Internal audit, external audit and regulators' recommendations. They provide relevant independent information on inherent and residual risk and identify areas for improvement in controls and processes. • Capital model. This is a model that captures the Bank's risk profile, based primarily on information gathered from the internal loss database, external data and scenarios. The main application of the model is to determine the economic capital for operational risk and the estimation of expected and stressed losses, which are used in the operational risk appetite. • Other specific tools to further analyze and manage operational risks include assessing new products and services, managing business continuity plans, and updating the operational risk program's perimeter and quality review processes. The Bank's operational risk management and reporting system support programs and tools focusing on governance, risk and compliance. It provides information for management and reporting and helps improve decision-making in operational risk management by consolidating information, simplifying the process, and avoiding duplication. Operational continuity plan Digital transformation is revolutionizing the way banks operate, presenting new business opportunities while also giving rise to a wide range of emerging risks, such as technology risks, cyber risks and an increasing reliance on suppliers, which increases exposure to events that may affect the delivery of services to our customers. The Bank is highly committed to ensuring robust control of the environment as determined by the best industry standards. This seeks to strengthen our operational resilience to potentially disruptive events, thereby ensuring adequate service delivery to our customers and system stability. One of the main pillars is a business continuity management system aimed at ensuring the continuity of business processes in the event of a disaster or major incident. This process identifies the potential impacts that threaten the entity, supplying the correct protocols and governance to ensure an effective response capability. Its main objectives are: • To protect the integrity of people in a contingency situation. • To ensure that core functions are performed, and the impact on service delivery to our customers is minimized in contingency events. • To meet the Bank's obligations to its employees, customers, shareholders and other stakeholders. • To comply with regulatory obligations and requirements. • To minimize the entity's potential financial losses and impact on the business. • To protect the brand image, credibility and trust in the entity.

NOTE 47 - RISK MANAGEMENT AND REPORTING, continued • To reduce operational effects by providing effective procedures, priorities, and strategies for recovering and restoring business operations following a contingency. • To contribute to stabilizing the financial system. The pandemic challenged the business continuity planning frameworks and strategies. While some protocols had to be adapted, this crisis demonstrated that the Bank has a robust Business Continuity Management system. Relevant mitigation measures The Bank implements and monitors mitigation measures related to the main sources of risk through internal operation risk management tools and other external sources of information. Business transformation and digitalization bring new risks and threats, such as increased payment fraud and origination (credit) fraud. We improved control mechanisms and designed new products to mitigate these risks. Strong authentication processes in the customer enrollment process and the reinforcement of anti-fraud alerts in origination are increasingly widespread resources to mitigate the risk of fraud. In the case of cards, the use of chip and PIN cards in shops and ATMs, two-step authentication with one-time passwords (dynamic verification passwords), reinforced security at ATMs through the incorporation of physical protection and anti-skimming elements, as well as improvements in the logical security of these devices. In the case of Internet banking, verification of online banking transactions with a second security factor of one-time passwords, implementation of specific protection measures for mobile banking, such as identification and registration of customer devices, monitoring of the security of the e-banking platform to prevent attacks on the systems, among others. Cybersecurity Cybersecurity threats are expected to increase. The financial sector is expected to be one of the main targets. With the increased reliance on digital systems, cybersecurity is one of the main non-financial business risks. Therefore, our goal is to make the Bank a cyber-resilient organization that can quickly resist, detect, and respond to cyber-attacks by constantly evolving and improving its defenses. In this area, the Bank continues to develop its control and monitoring framework in line with the best international practices. Outsourcing of services In order to be consistent with our digitization strategy, the Bank aspires to present its customers with the best solutions and products on the market. This implies increasing services provided by third parties and the intensive use of new technologies such as cloud services. In addition, due to increasing cyber risks and regulatory requirements, we have updated and strengthened the supplier management framework, internal control framework and risk culture to ensure that risks associated with third-party procurement are properly assessed and managed. The Bank has identified the suppliers that could present a higher level of exposure to our operations and the services provided to our customers. Accordingly, it has reinforced the monitoring of these suppliers to ensure that: • They have an appropriate control environment, depending on the level of risk of their service. • Business continuity plans are in place to ensure service delivery in case of disruptive events. • They have controls to protect sensitive information processed during the delivery of their services. • Contracts and agreements with third parties include the necessary clauses to protect the interests of the Bank and our clients, while at the same time covering existing legal obligations. • There are exit strategies, including service reversion or migration plans, in the case of services with a strong impact on business continuity and high replacement complexity.

NOTE 48 - INFORMATION ON REGULATORY CAPITAL AND CAPITAL ADEQUACY INDICATORS General Information The Bank provides information on the objectives, policies, and processes for managing capital and regulatory capital, respectively, in accordance with paragraphs 134–136 of IAS 1. Capital Description The Conceptual Framework establishes a concept of Financial Capital and one of Physical Capital. In this regard, the Bank applies the concept of Financial Capital, which translates into the consideration of invested money or invested purchasing power; capital is synonymous with the entity’s net assets or equity. The definition of regulatory capital was changed in December 2021, and is now defined as follows: • Paid-in capital from subscribed and paid common shares of the Bank; • Premium paid for instruments included in this component of capital; • Reserves, whether from earnings or not, from depreciation of perpetual bonds and expiry of perpetual bonds; • Items under “other accumulated comprehensive income”; • Retained earnings from prior periods, profit (loss) for the year, net of provisions for minimum dividends, revaluation of perpetual bonds, and payment of interest and/or dividends on regulatory capital financial instruments issued; • Non-controlling interest as indicated in the CASB. Objectives The Bank’s main objectives in Capital Management include: • Meeting internal capital and capital adequacy goals; • Complying with regulatory requirements; • Aligning the Bank’s strategic plan with the capital expectations of external stakeholders (rating agencies, shareholders and investors, clients, supervisors, etc.); • Supporting business growth and any strategic opportunities that may arise. Policies The Bank has an Asset and Liability Committee (ALCO), which is responsible for supervising, authorizing, establishing policies, and evaluating all aspects related to capital and solvency. The Board of Directors has delegated to ALCO the oversight and assessment of capital levels and returns consistent with the Bank’s strategy. The Integral Risk Committee (IRC) monitors and is responsible for the primary and secondary metric limits based on the risk appetite. Additionally, the Bank has developed the necessary policies to support the management and fulfillment of capital management strategies and objectives, including: - Capital Adequacy Policy; - Capital Planning Policy; - Policy for Managing Capital Deterioration Situations; - Capital Monitoring Policy; - Dividend Policy and Basel III Implementation.

NOTE 48 - INFORMATION ON REGULATORY CAPITAL AND CAPITAL ADEQUACY INDICATORS, continued Capital Management Processes Capital is managed in accordance with the risk environment, Chile’s economic performance, and the economic cycle. The relevant Committee may adjust our current capital policies to address changes in the aforementioned risk environment. Capital management is based on a Capital Framework aimed at ensuring that the level, structure, and composition of capital are adequate at all times, considering the Bank's risk profile and various scenarios. This framework ensures compliance with both minimum regulatory requirements and the Bank’s risk appetite and Recovery Plan, aligning with the interests of all stakeholders and supporting the growth strategy defined by the Bank. The capital model defines the functional and governance aspects related to capital planning, budget execution and monitoring, capital adequacy analysis, capital measurement, and capital-related reporting and disclosure. This model covers the main capital management activities: 1. Setting solvency and capital contribution targets aligned with minimum regulatory requirements and internal policies, to ensure a solid capital level consistent with the Bank's risk profile, and efficient use of capital to maximize shareholder value. 2. Developing a capital plan to meet these objectives in line with the strategic plan. 3. Assessing capital adequacy to ensure the capital plan aligns with the Bank’s risk profile and risk appetite (including stress scenarios). 4. Developing the capital budget as part of the Bank’s budgeting process. 5. Monitoring and controlling budget execution and developing action plans to correct any deviations from the budget. 6. Calculating capital metrics. 7. Preparing internal capital reports, as well as reports for supervisory authorities and the market. Compliance with Capital Management Objectives The Bank continuously evaluates its risk-return ratios through its core capital, effective equity, economic capital, and return on capital. Regarding capital adequacy, the Bank conducts its internal process based on the FMC standards in effect since December 1, 2021 (Basel III). Economic capital refers to the capital required to support all the risk arising from business activities at a given level of solvency. The monitoring and oversight of capital metrics and their limits are carried out by the ALCO, which also evaluates capital levels and risk appetite on a monthly basis, in addition to monitoring the solvency ratio “Regulatory Capital / Risk-Weighted Assets,” which, as of December 1, 2025, has been monitored on a fully loaded basis, considering capital requirements at 100% enforceability. Quantitative Data on Capital Management The Bank primarily manages its capital by increasing its effective equity through the accumulation of earnings. This approach enables it to maintain a minimum regulatory capital-to-risk-weighted-assets ratio of 16.61%, which is 3.98% percentage points above the required minimum External Requirements Minimum Required Capital According to the General Banking Law, as amended by Law 21,130, a bank must maintain a minimum of UF 800,000 (approximately Ch$32,656 million or US$35 million as of March 31, 2026) in paid-in capital and reserves, calculated in accordance with FMC regulations.

NOTE 48 - INFORMATION ON REGULATORY CAPITAL AND CAPITAL ADEQUACY INDICATORS, continued Capital regulatory framework and updates According to the new General Banking Law (as updated by Law 21,130), the minimum capital requirements have increased both in amount and quality. The total regulatory capital remains at 8% of risk-weighted assets, but now includes credit, market, and operational risks. The minimum Tier 1 capital requirement has increased from 4.5% to 6% of risk-weighted assets, of which up to 1.5% can consist of Additional Tier 1 (AT1) capital—such as preferred shares or perpetual bonds, which may be convertible into common shares. Tier 2 capital is now set at 2% of risk-weighted assets. Chapter 21-1 of the UCBR defines the components of regulatory equity. Additional capital requirements are incorporated through a capital conservation buffer of 2.5% of risk-weighted assets (UCBR 21-12). Furthermore, the Central Bank, subject to prior agreement with the FMC, may establish an additional countercyclical buffer of up to 2.5% of risk-weighted assets, in accordance with FMC regulations (UCBR 21-12). Both buffers must be composed of Common Equity Tier 1 capital. In addition, the FMC has been authorized—subject to the favorable agreement of the Board of the Central Bank of Chile to define, through regulation, new methodologies for calculating risk-weighted assets for credit risk (UCBR 21-6), market risk (UCBR 21-7), and operational risk (UCBR 21-8); the conditions for issuing hybrid AT1 instruments; the determination of capital charges for domestic systemically important banks; prudential deductions from regulatory capital; and to require additional measures, including higher capital, for banks that exhibit deficiencies in the supervisory capital assessment process (Pillar II). Pillar II aims to ensure that banks maintain a level of capital consistent with their risk profile and to promote the development and use of sound risk monitoring and management processes. To this end, banks are responsible for developing an internal capital adequacy assessment process, and supervisors must review banks’ strategies and internal assessments and intervene at an early stage if they are not satisfied with the outcome of this process. Supervisors may require additional capital above the minimum required to ensure a sufficient level to withstand risks, particularly during adverse credit cycles According to the General Banking Law, banks must maintain a regulatory capital of at least 8% of risk-weighted assets, net of required credit losses, and a requirement for paid-in capital and reserves ("core capital") of at least 3% of total assets, also net of credit losses. Regulatory capital is defined as the aggregate of: • The bank’s paid-in capital and reserves, excluding capital attributable to subsidiaries and foreign branches, or core capital; • Perpetual bonds and preferred shares referred to in Article 55 bis of the GBL, issued by the bank and valued at the issuance price, up to one-third of its core capital; • Subordinated bonds, valued at their issuance price, with a 20% annual reduction starting six years before maturity, up to 50% of its core capital; and • Additional provisions for credit losses, up to 1.25% of credit risk-weighted assets. On January 16, 2026, the FMC reported on the application of the capital requirement under Pillar II. The statement indicated that the board approved Exempt Resolution No. 862 regarding this application, which stipulates that the Bank must maintain the additional capital requirement of 0.25%, applicable at the 50 percent level it has maintained since June 30, 2025. On March 30, 2026, the FMC reported on the annual rating of systemically important banks and established requirements. The statement indicated that the board approved Resolution No. 3,399 regarding this rating, thus maintaining, for another year, the requirement for an additional 1.5% core capital charge for the bank.

NOTE 48 - INFORMATION ON REGULATORY CAPITAL AND CAPITAL ADEQUACY INDICATORS, continued On April 30, 2026, the FMC announced that, following the completion of two public consultation processes, it had issued regulations updating the minimum capital, guarantee, liquidity, and leverage requirements applicable to Securities Intermediaries and Commodity Exchange Brokers. The regulations introduce a risk-weighted asset methodology, in accordance with the amendments introduced by Law No. 21,521 to Laws No. 18,045 and No. 19,220. These regulations, which also repeal General Rule No. 18 (NCG No. 18), Circular No. 632, and Circular No. 695, will become effective on March 1, 2027. At its Financial Policy Meeting (FPM) held on November 19, 2024, the Board of the Central Bank of Chile agreed to maintain the Countercyclical Capital Buffer (CCyB) at 0.5% of risk-weighted assets, which had been activated on May 24, 2023. This requirement remained unchanged as of the end of June 2026. On May 18, 2026, the BCCh decided to continue the convergence of the CCyB toward its neutral level, setting it at 1% of risk-weighted assets, effective as of May 2028. Compliance with external requirements Regulatory capital and core capital are calculated based on the Interim Consolidated Financial Statements prepared in accordance with the CASB issued by the FMC. As a result of the merger between two predecessor institutions with a significant market share in the Chilean financial market, our current minimum regulatory requirement consists of a minimum regulatory capital-to-risk- weighted assets ratio of 12.63%, As of the reporting date, the Bank maintains a regulatory capital-to-risk-weighted assets ratio of del 16.61%. Period-to-period changes Schedule of changes to minimum capital requirements: June 30, 2026 December 31, 2025 % % Requirements Pillar II charge 0.13% 0.13% Systemic Charge 1.50% 1.50% Counter-cyclical Capital buffer 0.50% 0.50% Capital Conservation 2.50% 2.50% Tier T2 2.00% 2.00% AT1 1.50% 1.50% CET1 4.50% 4.50% Total 12.63% 12.63% As of December 1, 2025, the regulatory adjustments and exclusions set forth in UCBR 21-1 increased from a 65% to a 100% deduction, in accordance with the transitional provisions, thereby completing the phased implementation process of Basel III. Other Announcements and Statements Pillar III promotes market discipline and financial transparency through the disclosure of meaningful and timely information. This enables users to better understand the risk profile and capital structure of local banking institutions, thereby reducing information asymmetries. On July 8, 2025, the FMC published Circular No. 2,365 - Adjustments to Chapter 21-13 of the UCBR for the determination of additional regulatory capital requirements for banking entities, as a result of the supervisory process known as Pillar II of Basel III. The new regulatory adjustments published introduce improvements to Chapter 21-13 of the UCBR , with the objective of facilitating the supervisory process and clarifying some aspects of the capital evaluation process. The adjustments will be incorporated partially, with an initial application starting with the reports reported in December 2025 and will finalize in the review of the ICAAP, which will be delivered in April 2027.

Section 1: Highlights Solid financial performance with a 31.5% ROAE1 in 2Q262 and a 40.0% increase in earnings for the quarter. In the second quarter of 2026, net income attributable to the Bank's owners totaled $383 billion ($2.00 per share and US$0.90 per ADR). Compared to the previous quarter (1Q26), net income attributable to the Bank's owners increased 40.0% QoQ3 and 40.4% compared to 2Q254, primarily due to higher net income from readjustments in a quarter characterized by higher inflation (2.5% vs. 0.3% in 1Q26 and 1.0% in 2Q25), in addition to lower loan loss provisions during the quarter. As a result, ROAE increased from 24.5% in 2Q25 and 23.0% in 1Q26 to 31.5% in 2Q26. As of June 30, 2026, net income attributable to the Bank's owners totaled $656 billion ($3.48 per share and US$1.51 per ADR). Compared to the same period of the previous year, net income increased by 19.2%, reaching a ROAE of 27.2% in 6M26 versus 25.1% in 6M255. This is mainly due to higher net interest income resulting from higher inflation in the readjustment income line, as the UF variation was 2.7% in 6M26 compared to 2.2% in 6M25. Higher results from financial transactions and lower operating expenses also contributed to this improvement. Furthermore, at the shareholders' meeting in April 2026, it was agreed to distribute 60% of the 2025 profits as dividends. This represents a dividend of $3.35 per share and a yield of 4.5%. The Bank maintains a solid CET1 ratio6 of 11.1% with a BIS ratio7 of 16.6% as of June 2026. Net interest and inflation-linked income increased 26.9% QoQ with a NIM8 of 4.7% in 2Q26. In 2Q26, total net interest and inflation-linked income increased by 26.9% compared to 1Q26, primarily due to a strong 441.2% increase in inflation-linked income in 2Q26. This was driven by the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account) inflation rate, which rose from 0.3% in 1Q26 to 2.5% in 2Q26, due to the inflationary shock from oil prices. As a result, the NIM for the quarter increased from 3.8% in 1Q26 to 4.7% in 2Q26. Net interest and inflation-linked income YTD to June 30, 2026, increased 7.4% YoY9, with net interest income growing 5.4% and net readjustment income growing 17.7%. As a result, the net interest margin (NIM) increased from 4.1% in 6M25 to 4.3% in 6M26. 4 1Net profit attributable to owners of the Bank annualized divided by the average equity attributable to equity holders. 2Second quarter of 2026. 3Quarter versus quarter. 4Second quarter of 2025. 5The six months ending on June 30, 2025. 6Common Equity Tier 1 under Chilean regulation. 7Basel ratio (Tier 1 + Tier 2) under Chilean regulation. 8NIM: Net interest margin.

Total deposits grew 4.5% in the quarter. In the quarter, total deposits increased 4.5% QoQ, with time deposits growing 7.0% QoQ and demand deposits increasing 1.4% QoQ, related to our customers' increased liquidity in recent months. Mutual funds, meanwhile, grew 3.1% QoQ. Overall, customer funds grew 4.0% QoQ. Compared to December 31, 2025, our clients' funds grew by 7.1%. Total bank deposits increased by 6.0%, driven by an 11.8% increase in time deposits. Furthermore, there is a noticeable increase in client interest in mutual funds, which have grown by 9.5% since June 30, 2025. Total loans grow 1.3% QoQ, driven by commercial and mortgage loans Total loans at amortized cost increased 1.2% YoY compared to December 31, 2025, and 1.3% QoQ, reflecting growth in commercial, mortgage, and auto loans during the quarter. This was partially offset by lower growth in credit cards and consumer installment loans. This quarter we began to see an incipient improvement in growth in commercial loans increasing by 1.5% since December 31, 2025, and 1.3% QoQ. This trend is explained, firstly, by the impact of the Chilean peso's appreciation against the US dollar since December 2025, and by greater demand for foreign trade loans in recent months. Secondly, it reflects a slight improvement in the growth of non-foreign trade loans. Mortgage lending increased by 1.4% since December 31, 2025, and by 2.0% QoQ, due to a better origination dynamic and higher inflation in the quarter. Additionally, with an improved economic environment and new measures to encourage home purchases, we expect a gradual recovery in mortgage demand in the coming periods. Best in Class in Efficiency10 with 30.8% in 2Q26. The Bank's efficiency ratio reached 30.8% in the quarter, an improvement over the 32.5% recorded in 1Q26. This improvement was driven by higher net readjustment income due to higher inflation during the quarter and lower credit risk expenses, coupled with effective cost control. For the first six months of 2026, the efficiency ratio reached 31.6%, an improvement on the 35.3% registered in 6M25. Customer base expansion continues, with total customers increasing 6.9% YoY. The strategy of strengthening digital products has led to continued growth in our customer base, reaching over 4.8 million customers, of which 2.7 million are active.

strong, reaching 20.8% as of May 2026. Furthermore, increased use of digital platforms continued to drive fee income, with YoY growth of 10% in mutual fund brokerage and 26.6% in insurance brokerage. As a result, the recurrence ratio (total net fees divided by structural support expenses) increased from 61.9% YTD11 to June 2025 to 64.1% YTD to June 2026, demonstrating that almost two-thirds of the Bank's expenses are funded by customer-generated fees. 6 11 Year to date

Macroeconomic Environment During the second quarter of 2026, the Chilean economy operated in a still challenging external environment, marked by rising fuel prices due to the armed conflict in the Middle East. A brief improvement toward the end of the period was reversed in early July by renewed external tensions. Copper continued to act as the main external buffer for the economy, while the resurgence of geopolitical tensions amplified upward pressure on energy prices. Nevertheless, the economy remained exposed to the evolution of the global context and the volatility of international financial markets. Domestically, economic activity remained weak throughout the quarter. Domestic demand failed to consolidate a more dynamic trajectory, and private consumption faced a more restrictive outlook due to weak job creation and higher inflation that eroded real incomes. This was compounded by supply-side factors, such as the weakening fishing industry, which dragged down other sectors like manufacturing. At the same time, business confidence and economic expectations moderated compared to previous readings. In this context, the growth projection for 2026 was adjusted to 1.0% annually. The labor market remained fragile. The unemployment rate exceeded 9% in the March–May 2026 moving quarter, in a context where job creation remained limited and without clear signs of recovery. This employment performance, along with still-weak economic activity, continued to constrain the evolution of private consumption and the speed of the domestic recovery. In terms of prices, the quarter was marked by an inflationary surge primarily associated with the cost shock stemming from the conflict in the Middle East, although without significant signs of a second-round effect. The May CPI surprised on the downside with a monthly increase of 0.2%, while the June figure showed no change, which was nonetheless above market expectations and pushed annual inflation to 4.3%, from the previous 3.9%. Meanwhile, the June Monetary Policy Report (IPoM) reduced the projected growth range for 2026 to 1.0%-1.75% and raised expected inflation to 4.2%, in a scenario where the most likely path for the Monetary Policy Rate (MPR) remained at 4.5% for most of the projection horizon.

Financial market development As part of its market development agenda and refinement of the Basel III framework, the CMF published on April 13 the final regulations aimed at reducing regulatory friction in the repo and securitization markets. Among the main changes, the prudential treatment of repo transactions is simplified, the concept of significant risk transfer in securitizations is incorporated, the 1.250% weighting for retained instruments is eliminated, and adjustments are introduced to facilitate the registration of self-securitizations and the issuance of mortgage-backed securities. These measures should contribute to greater liquidity in the fixed-income market, strengthen the liquidity management of the banking system, and support a deeper and more competitive financial market. Then, on April 14, CMF President Catherine Tornel reinforced this agenda at the Capital Markets: Major Challenges 2026-2030 seminar, highlighting the institutional focus on market development. In that context, she announced progress in promoting the adoption of internal credit risk measurement models under Basel III, along with the creation of a specialized team for their validation. Finally, on July 3, the CMF held its second public consultation on the regulation updating the determination of Market Risk-Weighted Assets (MRWA), highlighting the following aspects: First, the duration method is incorporated for measuring overall interest rate risk, allowing for a more accurate reflection of variations in the economic value of positions in response to interest rate changes. Second, the current guidelines for excluding derivatives from interest rate risk estimation are refined, enabling the full offsetting of matched derivative positions even when they are not strictly identical. The CMF estimates that this will help reduce the system's MRWA by approximately 36%. 11
All these measures have the potential to contribute to the development of the financial system, although their final impact will depend on the depth to which the entities adopt the changes and on the evolution of the economic and financial cycle. Dividend Subsidy Law On May 20, 2025, Congress approved the Dividend Subsidy Law to facilitate access to homeownership and revitalize the real estate market. This initiative includes a subsidy of up to 60 basis points on mortgage interest rates. Furthermore, it is backed by a state guarantee from the Special Guarantee Fund (FOGAES) that covers up to 60% of the property value, which could further reduce the total interest rate by up to 100 basis points. The project aims to provide 50,000 subsidies, 10% of which are earmarked for first-time homebuyers valued up to 3,000 UF (Unidades de Fomento, a Chilean unit of account) and the remaining percentage for new homes valued up to 4,000 UF. To date, this program has been a significant factor in supporting the demand for mortgage loans. According to ABIF (Chilean Banking Association), as of June 19, 2026, 48,990 eligible applications had been received and commercially approved, a figure close to the 50,000-subsidy limit, and more than 26,948 mortgages had been processed. Pension Reform On January 29, 2025, Congress approved the pension reform after a lengthy process of considering various proposals. The main objective is to increase future and current pensions, taking into account the following changes. Pension contributions will increase by 7%, paid by employers, starting at 1% in August 2025 and gradually increasing over a period of 9 to 11 years. Of the total percentage, 6% will go to direct, deferred individual capitalization, and 1% to the new Social Security system, which will also include the current 1.5% allocated to Disability and Survivors' Insurance. These resources will allow for equal pensions for men and women in similar circumstances at the time of retirement. The reform also includes changes to the pension fund structure. The multi-fund system will be replaced by generational funds, and new administrators will be allowed to enter the system. A 10% share of the existing pension fund will be put out to tender every two years to increase competition. In addition, the reform proposes increasing the Guaranteed Universal Pension (PGU) to $250,000 pesos for the 90% of the most vulnerable population. More than a year after the law's enactment, the implementation of the pension reform continues to progress gradually according to the legal timeline. Significant milestones have been reached during 2026, such as the launch of the Single Contribution Collection System (SUCC), the commencement of pre-litigation collection by the General Treasury of the Republic, and the implementation of the new Social Security contributions. Furthermore, a new phase of increased employer contributions begins in August, while in September the Guaranteed Universal Pension (PGU) for individuals aged 75 and over will increase. While several operational measures have already been implemented, the final issuance of key regulations for the new individual capitalization system is still pending. Among these operational measures, mandates have already been awarded for the administration of the autonomous pension protection funds (FAPP), and the proposal for the Investment Regime for Generational Funds—currently open for public consultation—stands out. This 12
proposal will define the investment structure, risk limits, and benchmark portfolios of the funds that will replace the multi-funds starting in April 2027. Its final publication is one of the main regulatory milestones remaining for the reform. Beyond the details, it is commendable that the reform allows for a gradual recovery of pension savings levels. This is beneficial not only for financing future pensions but also for the capital market, insofar as a large part of this extra percentage is channeled under the current pension fund investment regime, even though the final impact will depend on the secondary regulations, which are still pending, and the investment rules of the new system. Interchange fees In February 2023, the Interchange Fee Limits Committee proposed new limits on the rates. These were approved at the end of April 2023, and a phased implementation was established. Card type Previous rate First cut (Oct-23) Current rate Second proposed cut (oct-24) (Suspended) Debit 0.6% 0.5% 0.35% Credit 1.48% 1.14% 0.80% Prepaid 1.04% 0.94% 0.80% In September 2024, just before the second rate reduction was to be implemented, the Committee decided to suspend the new phase of reductions, maintaining the existing limits, in order to assess the effects of the reductions already implemented on the functioning of the payments system. To this end, it was agreed to conduct an impact study to analyze market behavior and the foreseeable effects of a potential further rate reduction. Subsequently, and as recorded in the minutes of the Committee, the early termination of the contract with the external consultant in charge of the impact study was reported, due to the time elapsed and the lack of complete execution of the contract. To date, the future trajectory of interchange fees remains uncertain. The second rate cut remains suspended, and at the committee meeting on June 24, members evaluated and approved a new consultant to conduct the study. Consolidated debt In early June 2024, the law creating the Consolidated Debt Registry (REDEC) was passed. This registry consolidates information on outstanding loans granted to individuals. The registry will be public and free of charge, and will be managed by the Financial Market Commission (CMF). The legislation expands the scope of entities required to report, incorporating, in addition to banks and savings and credit cooperatives, mortgage loan administrators, compensation funds, credit card issuers regulated by the CMF, securitization companies, credit advisory entities regulated by the Fintec Law, and other entities that the CMF may determine through a General Regulation. Access to registry information will generally require the prior, express, and unequivocal consent of the debtor, granted for the assessment of their credit risk in a specific transaction and for a limited period, unless there is another legal basis for access under Law No. 19,628 or the information is anonymized. In July 2025, the CMF issued the REDEC operational framework, defining reporting obligations, applicable procedures, and information security and quality standards. 13
The regulations came into effect in April 2026, and since then the CMF has issued technical adjustments to the Information System Manual, resolved queries from reporting entities, and continued to incorporate new actors required to report. Regulatory priority has focused on stabilizing the system and ensuring the quality of reported information, a key element for proper credit risk assessment and the functioning of the financial market. Fintech and Open Finance Law The development of the Open Finance System (OFS) originated with the approval of the Fintec Law in 2023, which established the legal framework for the secure and consensual exchange of financial information among different actors in the system. In 2024, the CMF (Financial Market Commission) issued the specific regulations governing the OFS, defining the participation obligations for regulated financial entities and the conditions for the voluntary registration of new financial service providers. These regulations included an implementation timeline that set the system's entry into force within a two-year period, which raised concerns regarding operational feasibility, implementation costs, and the maturity of the proposed technical standards. During the last few months, the CMF issued three rules for public consultation aimed at adjusting the implementation schedule of the SFA, along with defining in greater detail the technological standards necessary for its implementation. The main recent milestone was the issuance of the final standard NCG No. 569, which contains the technical specifications for system interoperability and introduces a series of adjustments aimed at facilitating a gradual and secure implementation of the SFA. These include postponing the effective date until July 2027, incorporating a pilot period for controlled testing among participants, establishing a technological sandbox managed by the CMF, creating simplified participation mechanisms for smaller entities, and standardizing procedures to reduce operational friction. Despite these advances, key regulatory aspects remain to be defined, including the cost-sharing model between entities that provide information and those that consume it. In this context, the SFA remains a regulatory project under development, and its final design will be crucial in assessing its impact on competition, innovation, and compliance costs for financial institutions in Chile. In this context, in December 2025, the Central Bank authorized a local fintech company to operate a low-value payment clearinghouse, enabling potential future changes in the functioning of the payments market. Personal Data Protection Law In December 2024, a law was published modernizing the protection and processing of personal data in Chile, establishing a regulatory framework aligned with international standards such as those of the European Union. The legislation creates the Personal Data Protection Agency, the body responsible for overseeing compliance with the law, imposing sanctions, issuing guidelines, and promoting best practices in data processing. The law recognizes new rights for data subjects—access, rectification, erasure, objection, and portability—and establishes relevant obligations for organizations, such as implementing compliance programs, adopting security measures, managing incidents, and appointing a Data Protection Officer. The law is set to enter into force on December 1, 2026, and the first appointment to the Agency's Governing Board should have been made by Congress in June 2026. However, this appointment is still pending. 14
Draft Law on Reconstruction and Economic and Social Development The National Reconstruction and Economic and Social Development Bill is in its final stage of legislative processing. After being approved by the Senate with several modifications, the Chamber of Deputies is currently debating it in its third constitutional stage, placing the bill in the final stage of the legislative process. Among the most relevant measures is the tax agenda aimed at strengthening investment, improving competitiveness, and supporting economic recovery. Specifically, the bill includes a gradual reduction of the First Category Tax rate from 27% to 23%, one of the most significant tax modifications in recent years, along with the complete reintegration of the tax system. This measure is designed to simplify the tax structure, reduce the cost of capital, and provide greater incentives for private investment. It also incorporates a temporary VAT exemption for the sale of new homes, an initiative that seeks to accelerate the absorption of the large available housing stock, stimulate the real estate and construction sectors, and facilitate access to housing. Additionally, the bill includes incentives for formal employment, investment benefits, property tax exemptions for senior citizens, and the creation of a special fund for the reconstruction of areas affected by wildfires. The initiative also incorporates other relevant financial and regulatory modifications, some of which have been the subject of extensive debate during its legislative process. Guarantee management as credit risk mitigators In July 2026, the Financial Market Commission published Circular No. 2,373, which establishes a new prudential framework for the management, valuation, and recognition of collateral used by banks as credit risk mitigators. The regulation incorporates Chapter 21-10 of the Updated Compilation of Regulations and reinforces the responsibility of the Board of Directors and senior management regarding the policies, controls, and procedures applicable throughout the collateral lifecycle. The circular requires that guarantees be legally valid, enforceable, properly documented, and prudently valued, taking into account their liquidity, execution costs and timeframes, asset volatility, and market conditions. It also establishes obligations for periodic revaluation, traceability, safekeeping, independent monitoring, and recording of amounts actually recovered. Guarantees that do not meet these conditions may be withdrawn to reduce credit exposure, leading to higher provisions and potentially greater capital consumption. Most of the provisions will come into effect on January 1, 2028. However, the changes related to the assessment of the quality of guarantee management by the CMF are effective immediately, so banks must begin adapting their policies, valuation methodologies, information systems, controls and execution processes in advance. Regulation and supervision In Chile, only banks can maintain current accounts for their clients, conduct foreign trade operations, and, along with regulated non-bank financial institutions such as cooperatives, accept time deposits. The main authorities regulating financial institutions in Chile are the Financial Market Commission (CMF) and the Central Bank. Chilean banks are primarily subject to the General Banking Law and, secondarily, to the extent that it is not incompatible with this law, to the provisions of the Chilean Corporations Law governing corporations, except for certain provisions that expressly exclude them.

Main advances of the strategy Digital Bank with Work/Cafes The Bank's strategy is based on cutting-edge technology, along with processes and products designed with a customer focus. The Bank is building robust capabilities in digital channels, enabling secure, agile, and user- friendly onboarding. Through this approach, it offers digital accounts for the mass market, specific solutions for SMEs, and payment services via Getnet for entrepreneurs and small and medium-sized businesses. These initiatives not only drive digital adoption among our clients but also promote greater financial inclusion in these segments. The Bank facilitates an initial approach through transactional services, with the potential to expand its offerings to include other products and financing options, such as credit cards and loans. In parallel, the transformation of its branch network to the Work/Café model is a key pillar of its strategy. This approach considers the needs of customers in each region, offering spaces that not only meet their financial requirements but also provide a welcoming, comfortable, and friendly environment for interacting with the Bank. Customers: Customers: 2023 2024 2025 June 2026 Total customers 4,052,314 4,311,488 4,608,182 4,825,551 Loyal customers 850,905 1,305,953 1,378,876 1,348,309 Active customers 2,398,741 2,556,462 2,693,441 2,693,108 Digital customers 2,113,128 2,238,774 2,291,971 2,253,290 Total customers increased by 6.9% YoY, while active customers grew by 1.3% YoY.

According to the latest publicly available information from the CMF as of May 2026, the Bank holds a 20.8% share of all current accounts for both individuals and businesses, a figure that does not include demand deposit accounts. Meanwhile, demand for dollar current accounts continues to show positive growth. As of May 2026, the market share reached 36.4%, driven by the ease of online account opening and sustained customer demand for this type of product. In the SME segment, the number of accounts continues to grow strongly, supported by initiatives such as Getnet, the acquiring business, and offering 100% digital current accounts. These accounts include access to a debit card 19
and Office Banking, the transactional platform for businesses. This comprehensive approach allows the company to meet its clients' transactional needs and support them in the development and growth of their businesses.

Likewise, deepening relationships with this segment and the convenience of digital channels contributed to a 3.3% YoY growth in the number of SME clients. Additionally, for those clients who meet the eligibility criteria, we offer credit cards and various financing options. Expansion in payment services Getnet's operations in Chile have solidified its position as a leading player in the acquiring market, distinguished by strong growth and increasing market share. As of June 2026, it has over 287,000 operational POS terminals and more than 229,000 affiliated merchants, along with a payment solutions ecosystem that blends physical and digital presence, positioning it as one of the most dynamic networks in the country. This development has also been reflected in solid financial results and sustained expansion in transactions and processed volumes. Getnet's value proposition has evolved into an omnichannel model, integrating solutions for in-person payments, e-commerce, and value-added services, tailored to different types of businesses, from entrepreneurs to larger companies. In particular, its offering for SMEs has been key to driving the digitization of payments, while the development of more sophisticated solutions—such as integrations and customized services—has allowed it to expand its reach to corporate clients. Furthermore, Smart POS devices have expanded their functionality beyond simply accepting payments, becoming true service platforms for businesses. Today, they allow, for example, bill payments, mobile top-ups, and other transactions, contributing to increased customer traffic and generating new business opportunities for partner merchants. This is further complemented by the sustained growth of the e-commerce channel, which has become a key pillar of Getnet's offering, supporting the digitalization of commerce in Chile. 20
More than 40% of our branches operate on a cashless basis. As of June 2026, the Bank has a total of 224 branches, 123 of which operate under the traditional format. Since launching the Work/Café model in 2016, 91 branches have opened throughout Chile. This format includes different variations, such as Work/Café Investments, StartUp, Expresso, and Standard. Furthermore, the Bank is working on renovating traditional branches to adopt the Work/Café look and feel, a process that has already been completed at 18 branches. Within this network, the Work/Café Expresso locations stand out. Designed as transactional centers, they integrate teller and self-service options, service desks, card printing machines, and lockers for product delivery. All of this is offered in a modern and efficient environment, allowing customers to conduct their transactions quickly and securely, significantly improving their experience. These branches, supported by advanced technology, also generate significant efficiencies in cash management, contributing to the optimization and consolidation of our network. In this context, efficiencies continue to be captured in the branch network, with more than 40% of them currently operating on a cashless basis. In line with the strategy, customers are more satisfied with digital channels As a result of all the efforts with digital channels, customers are showing greater satisfaction with these service channels.

Section 5: Segment information Segment information is based on the financial information presented to senior management and the Board of Directors. The Bank has aligned segment information consistently with the underlying information used internally for management reporting purposes and with that presented in other public documents of the Bank. Senior management has been determined to be primarily responsible for the Bank's operational decision- making. The Bank's operating segments reflect its organizational and management structures. Senior management reviews internal information on a segment basis to assess performance and allocate resources. As of March 31, 2026, the Bank revised the identification of its operating segments to reflect changes in its internal management structure and in how the Chief Operating Decision Maker (CODM) evaluates performance and allocates resources. Consequently, comparative information has been restated for consistency with the current period's presentation. Management believes this revised presentation provides more relevant information for users of the financial statements. In order to achieve the strategic objectives set by senior management and adapt to changing market conditions, the Bank periodically makes adjustments to its organization. These modifications, in turn, impact, to a greater or lesser extent, how the Bank is managed and administered. This disclosure provides information on how the Bank is managed as of June 30, 2026.

This trend was partially offset by slower growth in consumer loans, particularly credit cards, due to improved liquidity among our clients, as evidenced by the 4.0% increase in deposits in this segment compared to December 31, 2025, and a 4.3% QoQ increase. Net operating income for this segment increased 7.6% YoY and 42.2% QoQ, driven by a higher margin, though impacted by higher inflation of 2.5% during the period. Provisions also decreased by 23.9% in the quarter due to the reversal of a provision established in 1Q26 for a corporate client. However, provision expenses increased 3.2% YoY due to higher provisions in line with the evolution of asset quality, explained in more detail in Section 8: Risks. Wealth Management & Insurance (WM&I) Wealth Management & Insurance's loan portfolio grew 8.3% YoY and 2.9% QoQ, driven by higher general- purpose commercial and mortgage loans. Deposits increased 1.6% YoY and 5.2% QoQ, reflecting our clients' improved liquidity position during the quarter. Net operating income increased 20.4% YoY and 7.1% QoQ, primarily due to higher margins driven by growth in client loans and funds. Additionally, compared to 2025, net income in this segment is projected to increase due to higher fees generated by mutual funds and travel-related insurance. Corporate Investment Banking (CIB) CIB's loan portfolio grew by 2.1% YoY and 2.5% QoQ, reflecting improved performance compared to previous periods, particularly in the foreign trade portfolio during the last quarter. Deposits increased by 13.2% YoY and 4.7% QoQ, thanks to strong relationships with these clients and an improvement in their liquidity position. Net operating income increased 11.5% YoY but decreased 20.8% QoQ explained by stronger margin growth and results from financial transactions, associated with client demand for fixed-income market-making products, which peaked in 1Q26. This was offset by lower commission performance in the quarter due to lower M&A advisory services and the establishment of provisions in the quarter following a release in 1Q26. 26
Payments Payments had a weaker quarter with less transactional activity from customers due to increased market competition and therefore greater price pressure. Digital Consumer Bank Digital Consumer Bank's loan portfolio grew 4.9% YoY and 1.8% QoQ. Net operating income increased 25.9% YoY and 19.2% QoQ, driven by strong fee growth in the quarter, including higher insurance collections and higher margins thanks to portfolio growth. 27

Total gross loans of provisions at amortized cost. Total loans at amortized cost increased by 1.2% compared to December 31, 2025, and by 1.3% QoQ, driven by growth in commercial, mortgage, and auto loans. In contrast, credit card and installment purchase loans showed slower growth during the period. Approximately 57% of the loan portfolio is indexed to the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account), given that most mortgage loans and about 35% of commercial loans are denominated in this unit. Additionally, around 21% of commercial loans are denominated in foreign currency, primarily US dollars. Consequently, the performance of these loans has shown some volatility in recent quarters, associated with exchange rate fluctuations. In recent periods, demand for commercial loans remained limited, particularly among large corporates. However, during the quarter, incipient signs of recovery began to emerge, with growth of 1.5% since December 31, 2025, and 1.3% QoQ. This trend was primarily driven by increased demand for financing for foreign trade operations, the effect of which was partially offset by the appreciation of the Chilean peso against the US dollar since December 2025. Secondly, a slight improvement in the growth of non-foreign trade loans was also observed. Mortgage originations increased by 1.4% since December 31, 2025, and by 2.0% QoQ, largely due to a better sales dynamic and higher inflation in the quarter. In recent periods, new loan origination has slowed, reflecting still-weak demand, impacted by rising house prices, as well as the level of inflation and interest rates observed in previous years. However, with an improved economic environment and new measures to encourage home 28
buying, such as those included in the Reconstruction Reform, we expect a gradual recovery in mortgage demand in the coming periods. Consumer loans increased slightly by 0.1% as of December 31, 2025, and decreased by 0.6% QoQ. Within consumer loans is the auto finance business, Santander Consumer, which has shown positive trends with an increase of 4.1% as of December 31, 2025, and a QoQ increase of 1.0% thanks to more commercial agreements with car dealerships. Credit card debt decreased by 1.5% YTD and 2.0% QoQ, while consumer installment loans also declined slightly. This is explained by our customers' improved liquidity position during the quarter, where their funds increased by 4.0% QoQ.

Calculated in accordance with Chilean regulations. The Bank's total deposits increased by 6.0% since December 31, 2025, driven by an 11.8% growth in time deposits, primarily due to increased inflows in the CIB segment. This was partially offset by a slight contraction in demand deposits, associated with normal seasonality compared to year-end. We also saw increased demand for mutual funds, which grew by 9.5% over the same period. Overall, client funds grew by 7.1% since December 31, 2025. In the second quarter (2Q26), total deposits increased by 4.5%. Time deposits grew by 7.0%, while demand deposits increased by 1.4% QoQ. Mutual funds, meanwhile, increased by 3.1% QoQ. Overall, customer funds grew by 4.0% QoQ. Bonds declined 7.6% YoY and 3.5% QoQ, in line with increased liquidity among our clients and slower demand in the long-term loan portfolio. Through June 2026, the Bank issued bonds totaling UF 6,562,000, Ch$ 248,500,000,000, and USD 530,000,000, taking advantage of favorable conditions in both local and international fixed-income markets. Of particular note was the issuance of a USD 500 million 144A bond in January 2026, maturing in November 2030 with a 4.55% interest rate. In terms of liquidity, the Bank's Liquidity Coverage Ratio (LCR), which measures the percentage of liquid assets relative to net cash outflows, stood at 177.1% as of June 30, 2026, well above the regulatory minimum. At the same date, the Bank's Net Stable Funding Ratio (NSFR), which measures the percentage of illiquid assets financed through stable funding sources, was 118.2%, also significantly above the required minimum. 30

This growth is primarily due to reserves resulting from higher profits in fiscal year 2025. Compared to the previous quarter, equity increased 5.0% QoQ due to higher profits and a lower loss recorded in valuation accounts associated with cash flow hedges. The Bank uses these hedges to mitigate the inflation risk of its assets. In the current context of inflation expectations, this has generated an unrealized gain during the quarter. As of June 2026, the Bank maintains a dividend provision of 60% of 2026 profits. At the Annual Shareholders' Meeting held on April 28, 2026, the distribution of a dividend of 60% of the 2025 profits, equivalent to Ch$ 631,925 million, and a dividend per share of Ch$ 3.35 with a yield of 4.5%, was approved. The Bank had already fully provisioned for this dividend. 31

Leverage: Core capital / Total regulatory assets, as calculated by the CMF. Risk-weighted assets (RWAs) increased 5.0% as of December 31, 2025, primarily driven by market RWAs, in a context influenced by global market volatility. During the quarter, our RWAs remained stable at 0.1% QoQ, with a decrease in market RWAs during the quarter, offset by growth in loan RWAs, in line with the growth of the loan portfolio. Regulatory capital has strengthened thanks to higher profit generation, allowing the CET1 ratio to increase organically by 20 basis points as of December 2025, reaching a ratio of 11.1% at the end of 2Q26, above the minimum requirement of 9.08%. Meanwhile, the total BIS ratio reached 16.6% at the close of June 2026. Finally, the ROAE for the last 6 months (6M26) reached 27.2% and 31.5% in the quarter, with the second quarter positively impacted by higher inflation during the period. 32

Net interest and readjustment income accumulated to June 30, 2026 increased by 7.4% compared to the same period in 2025. This growth was driven by a 17.7% increase in readjustment income, favored by a UF variation of 2.7% in 6M26 compared to 2.2% in the same period in 2025. In a context of lower inflation during the first quarter, average exposure to the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account) decreased on average during 2026 compared to 2025. However, given the inflationary rebound recorded during the second quarter, the Bank increased this exposure to capture the higher inflation observed in recent months. Meanwhile, interest income increased by 5.4%, driven primarily by the 3.5% growth in average interest-earning assets and, to a lesser extent, by a slight improvement in funding costs, in line with the decrease in the average Monetary Policy Rate (MPR) from 5.0% to 4.5%. The Bank maintains a shorter duration for its interest-bearing liabilities compared to its assets, allowing liabilities to adjust more quickly to changes in interest rates. As of June 2026, time deposits represented 35.9% of total funding and, given that they typically have a duration of 30 to 60 days, they rapidly capture changes in interest rates. In 2Q26, total net interest and readjustment income increased by 26.9% compared to 1Q26, primarily due to strong growth in readjustment income of 441.2% in 2Q26, where the UF variation increased from 0.3% in 1Q26 to 2.5% in 2Q26. Given the change in the inflation environment, we increased the gap in inflation-linked instruments in the quarter. This was offset by a slight decrease of 2.1% in interest income for the quarter, explained by a higher cost of funds. Compared to 2Q25, total net interest and readjustment income increased by 19.4% in 2Q26, primarily due to the impact of higher inflation, which rose from 1.0% in 2Q25 to 2.5% in 2Q26, leading to a strong increase in readjustment income of 104.8%. Furthermore, interest income grew by 2.8% in 2Q26 compared to 2Q25, driven by a 3.9% increase in interest-earning assets during the period. As a result of these inflationary dynamics, the net interest margin (NIM) increased from 4.1% in 2Q25 and 3.8% in 1Q26 to 4.7% in 2Q26, and from 4.1% in 6M25 to 4.3% in 6M26. 34

Annualized credit loss expense divided by average loans. 2. Balance sheet provisions including additional provisions divided by non-performing loans. The Bank's asset quality continued to reflect the economic environment facing both corporate and retail banking clients. The slower economic activity and weakening labor market observed in recent years resulted in higher levels of non-performing loans and impaired portfolios, requiring a greater level of loan loss provisions. In this context, during 2025 the Bank implemented several initiatives aimed at strengthening portfolio quality, particularly in the commercial segment. During the first quarter of 2026, asset quality indicators remained relatively stable, although one isolated case was recorded in the large corporate segment. This effect was partially reversed during the second quarter, contributing to a decrease in net loan loss expenses. Net credit loss expense totaled Ch$285,583 million in 6M26 and Ch$126,806 million in 2Q26, representing a decrease of 0.4% compared to the same period in 2025, 20.1% compared to 1Q26, and 13.9% compared to 35
2Q25. As a result, the cost of risk increased from 1.43% in 2Q25 to 1.55% in 1Q26 and improved to 1.22% in 2Q26, reaching 1.38% in 6M26. The impaired loan ratio increased from 6.8% in 2Q25 to 7.5% in 2Q26, reflecting loan restructuring. Consequently, the non-performing loan (NPL) ratio increased from 3.0% in 2Q25 to 3.4% in 2Q26, although the pace of deterioration appears to be moderating. It is important to note that asset quality indicators are being impacted by low portfolio growth. Finally, the expected loss ratio (provisions for credit risk divided by total loans) has increased from 3.2% in 2Q25 to 3.3% in 2Q26 as a result of higher provisions established in recent periods, and the non-performing loan coverage ratio (which includes voluntary provisions set out by the Board of Directors in recent years) is at 107.6% in 2Q26.

During the quarter, there were greater recoveries of non-performing consumer loans, and as a result, the non-performing loan ratio for the consumer portfolio improved from 2.2% in 2Q25 and 1Q26 to 2.1% in 2Q26. Meanwhile, the non-performing loan ratio for the consumer portfolio increased from 5.1% in 2Q25 to 5.2% in 1Q26 and 2Q26, indicating greater restructuring of customers during 2026. Consumer loan coverage reached 387% at the end of June 2026. Provisions for commercial loans decreased by 33.2% in 6M26 compared to 6M25, primarily due to lower provisions for the commercial loan portfolio assessed as on a group basis. As mentioned previously, in the first quarter of 2026, a specific company in the mining sector experienced difficulties, leading to an increased provision and the use of additional provisions to cover the client's exposure. Compared to 1Q26, provisions for commercial loans decreased by 72.1% in 2Q26 and by 78.8% compared to 2Q25 due to the release of provisions related to the aforementioned client. The non-performing loan ratio for the commercial loan portfolio increased from 3.6% in June 2025 to 3.7% in March 2026 and 3.9% in June 2026. The impaired loan ratio for commercial loans stood at 8.3% in 2Q25, 9.0% in 1Q26, and 9.1% in 2Q26, taking into account more loans restructured during 2025. On the other hand, the non-performing loan coverage ratio for this portfolio remained high at 119.3% as of June 2026. Provisions for mortgage loans decreased by 55.7% in the first six months of 2026 compared to the same period in 2025 due to lower provisions for non-performing loans and higher recoveries of previously written-off loans. 36
Compared to the previous quarter, they increased by 112.0% QoQ and by 758.2% compared to the second quarter of 2025 due to higher provisions for non-performing loans. The mortgage non-performing loan ratio stood at 3.4% for the quarter, with an impairment ratio of 6.6%. As a result, the non-performing loan coverage ratio for the mortgage portfolio remained at 34.2% in June 2026. For more information on credit risk and asset quality, see Section 8: Risk. Good performance in fees from brokerage of mutual funds and other major products. Net fees remained stable in the six months ended June 30, 2026 compared to the same period in 2025 mainly due to higher fees on our main products such as mutual fund brokerage and current accounts and offset by lower performance in transactional products and other fees. With this, the recurrence ratio (total net commissions divided by structural support expenses) increased from 61.9% YTD to June 2025 to 64.1% YTD to June 2026, demonstrating that almost two-thirds of the Bank's expenses are financed by the commissions generated by our customers.

Payment fees are primarily generated by Getnet, the bank's acquiring business. The fees from Getnet experienced a contraction in the quarter and in the first six months of 2026 due to a more competitive environment following a period of strong growth. It currently has approximately 287,000 POS terminals in operation, consolidating its presence in the payments ecosystem. 37
Brokerage fees for asset management and insurance increased 16.1% in 6M26 compared to the same period in 2025 and 14.1% compared to 2Q25, reflecting higher demand, as a result of the expanding customer base, for investment products in a context of lower interest rates and insurance products associated with consumer loans, as well as non-loan-related insurance such as life and auto insurance. Brokerage fees increased 1.5% QoQ also driven by insurance associated with mortgage and consumer loans. Current account and collection fees decreased 1.3% in 6M26 compared to the same period in 2025 and 1.6% compared to 2Q25, mainly due to lower income associated with loan collections and insurance premiums. In the quarter, current account and collection fees increased 0.4% QoQ due to higher fees from current account. Account openings continued to grow during the quarter, reaching a market share of 20.8% as of May 2026. Strong growth in dollar current accounts was also noteworthy, with digital account opening facilitating their adoption. As of May 2026, 507,584 accounts were registered, representing a market share of 36.4%. Other fees decreased by 6.2% in 6M26 compared to the same period in 2025, by 17.4% in 2Q26 compared to 2Q25, and by 36.2% QoQ. Fees for loan prepayments performed well, primarily due to higher prepayments on commercial loans during the quarter. Furthermore, fees from guarantees also showed increased activity in standby letters of credit and cash guarantees during the quarter, although less than in 6M25, when demand from corporate clients and large companies was particularly high. Also noteworthy during the quarter were higher commissions generated by financial advisory services related to client debt restructurings. However, the quarter also saw increased fee expense on guarantee services provided by multilateral development organizations seeking to promote the growth of certain portfolios. Net financial results income increased by 16.0% in 6M26.

This performance is mainly explained by higher gains in the valuation of derivative contracts and by the sale of commercial portfolio and available-for-sale portfolio, partially offset by lower results associated with the foreign currency position. 38
Net financial results increased by 11.8% compared to 2Q25, due to a better result from the valuation of derivative contracts, while this line decreased by 17.4% in 2Q26 compared to 1Q26 with a lower gain from the valuation of derivative contracts in the quarter offset by better results associated with the foreign currency position. For a better understanding of these lines, they are presented by business area in the following table: Net financial results by business: Non-accounting financial information YTD % Change Quarterly % Change Ch$ million Jun-26 Jun-25 Jun-26/ Jun-25 2Q26 1Q26 2Q25 2Q26/ 2Q25 2Q26/ 1Q26 Client 133,340 129,346 3.1% 62,626 70,714 59,244 5.7% (11.4%) Non-Client (1) 22,324 4,820 –% 7,780 14,544 3,706 109.9% (46.5%) Total net financial transactions 155,664 134,166 16.0% 70,406 85,258 62,950 11.8% (17.4%) 1. Non-client income. These results include interest and mark-to-market effects from the Bank's trading portfolio, realized gains from the available-for-sale portfolio, and other results from the Finance Division. Revenue from client treasury services reached Ch$133,340 million in 6M26, a 3.1% YoY increase and a 5.7% increase compared to 2Q25. This growth was driven by higher demand for fixed-income market making due to increased market volatility. However, revenue from client treasury services decreased by 11.4% QoQ, following a strong first quarter. Non-client treasury income totaled a gain of Ch$22,324 million, mainly explained by the sale of commercial portfolio and ALCO and better hedging results. Efficiency of 31.6% in 6M26 with operating expenses contracting YoY. The Bank's efficiency index reached 31.6% as of June 30, 2026, an improvement over the 35.3% recorded in the same period of the previous year. The efficiency ratio stood at 30.8% in 2Q26, compared to 32.5% in 1Q26 and 35.6% in 2Q25. In line with this, the cost-to-asset ratio decreased to 1.4% in the first six months of 2026. Operating expenses (which include other expenses) decreased by 4.3% compared to 6M25, primarily due to lower administrative costs. It's worth noting that during the first quarter of 2025, the Bank completed a major milestone with Project Gravity, which involved migrating from the mainframe to the cloud. During that period, both systems operated in parallel, resulting in higher costs. Furthermore, the transition to the new cloud infrastructure generated higher amortization and depreciation expenses associated with legacy systems. Compared to 1Q26, operating expenses increased by 7.8%, driven by higher personnel expenses. Personnel expenses in the first quarter of the year show seasonality due to the holiday season in Chile. Operating expenses decreased by 2.0% compared to 2Q25 due to lower personnel and other expenses. 39

Personnel expenses increased by 1.7% in 6M26 compared to 6M25, primarily due to salary readjustments in line with inflation and higher severance payments, in the context of a 4.0% reduction in staff and a 3.0% decrease in the number of branches. This was offset by lower short-term incentives. Compared to 1Q26, personnel expenses increased by 11.7%, mainly due to higher salaries, where, for accounting purposes, the holiday season causes seasonality in this account. This was partially offset by lower severance payments. Compared to 2Q25, personnel expenses decreased by 1.2%, explained by lower severance payments for years of service offset by higher spending on training and salaries in line with inflation. Administrative expenses decreased by 9.3% in 6M26 compared to the same period in 2025 due to lower technology and data processing expenses, largely related to the aforementioned Gravity project. Compared to 40
1Q26, administrative expenses increased by 3.4% due to higher IT and communications spending. Compared to 2Q25, administrative expenses remained stable. Depreciation expenses decreased 2.0% in 6M26 compared to the same period in 2025 and 2.2% in 2Q26 compared to 2Q25, primarily due to lower depreciation of internally developed software. Compared to 1Q26, depreciation expenses decreased 6.9% QoQ due to the aforementioned factors, in addition to higher equipment depreciation during the quarter. Other operating expenses decreased 11.6% in 6M26 compared to the same period in 2025, mainly due to the release of provisions associated with other contingencies in 1Q26. Compared to 1Q26, other operating expenses increased 49.7% QoQ due to the aforementioned release of provisions, which was not repeated in 2Q26. Compared to 2Q25, other operating expenses decreased 10.5% due to lower financial leasing credit operating expenses.

For tax purposes, capital must be adjusted for inflation; therefore, when inflation is high, the effective tax rate tends to be lower. As of June 2026, the effective tax rate was 14.6%. 41
Section 7: Management Perspectives The Bank's Management continuously evaluates the evolution of the economic, regulatory, and competitive environment, as well as trends that could influence the institution's future performance. In this context, the perspectives presented in this section reflect Management's current view of the main challenges, opportunities, and factors that could impact the Bank's ability to generate sustainable value and maintain a solid financial position in the short, medium, and long term. These perspectives consider the Bank's defined strategy, its risk profile, the expected evolution of the markets in which it operates, and the capabilities developed to respond to a constantly changing environment. Furthermore, Management continuously monitors financial, commercial, operational, and sustainability indicators to support timely decision-making and strengthen value creation for clients, employees, shareholders, and other stakeholders. With all of the above in mind, the Bank's expectations for growth in volumes, capital and results for the year 2026 are as follows: Indicator Initial expectation Updated outlook 2Q26 Key factor Loan growth Mid single digits Mid single digits Demand reactivation driven by macro environment. NIM C. 4.0% C. 4.1% Baseline macroeconomic environment for interest rates and inflation and the asset and liability mix. Non NII growth Mid to High Single Digits Mid-Single Digits Customer growth and product usage. Does not include potential regulatory changes related to interchange fees. Efficiency Mid 30s% Low 30s% Inflation, total employees, exchange rate, productivity, and investment plans. Cost of credit c. 1.3% c. 1.35% Subject to the evolution of the cycle. ROAE 22-24% +24% Based on our estimates of key components including inflation, rates, and business growth. Regarding capital management, on July 3, the CMF (Financial Market Commission) held a second public consultation on the regulation updating the calculation of market risk weighted assets (MRWA), which had a two-week deadline. The CMF estimates that this will help reduce the system's MRWA by approximately 36%. The Bank is awaiting the final regulation to calculate an estimate of the impact on capital ratios, which should be positive. The Bank's Research team projects stronger economic growth in 2027, coupled with inflation converging to the Central Bank's target range of 3% and a potential reduction in the monetary policy rate. This scenario should boost customer demand for loans in the coming year. In the long term, ROAE is estimated to be above 20%, subject to macroeconomic projections and other external factors. 42
Section 8: Risks Risk management in 2Q26 has focused on strengthening our risk structure in the face of weak economic activity and the labor market as described in Section 3 of this document. Credit risk Estimated expected loss: The provision estimate is based on expected loss models, in accordance with Chapter B1 of the CMF's Compendium of Accounting Standards. The loan portfolio is divided into loans analyzed as a group and loans analyzed individually. Within each group, there are different provisioning models for consumer loans, mortgages, and commercial loans. In simplified terms, provisions for most loans are determined using the following expected loss formula: Further information on the loan models can be found in note 2 of the Bank's financial statements. Below you can see more details of the loan portfolio. 43

During 2025, the Bank implemented several initiatives to strengthen portfolio quality, including write-offs. However, in the first quarter of 2026, a one-off deterioration was observed for a commercial client assessed on an individual basis. This led to an increase in the loan loss provision coverage for this exposure, which was reversed during the second quarter. As a result, the commercial non-performing loan ratio reached 3.9% in June 2026, while the impaired loan ratio increased from 8.6% in December 2025 to 9.1% at the end of June 2026. In the mortgage portfolio, a deterioration was observed during 2024, associated with lower household liquidity and an increase in the total installment in the recent years due to high inflation. During 2025, clients began renegotiating their loans, and NPLs showed signs of stabilization, reaching 3.1% in December 2025 and 3.4% in June 2026. Meanwhile, the impaired loan ratio reached 6.3% and 6.6%, respectively. It is worth noting that these loans are secured by real estate, maintaining a loan-to-value (LTV) ratio of around 60% of the outstanding loan portfolio. The consumer portfolio continues to show good performance with a stable impairment ratio of 5.2% and an improvement in the NPL ratio from 2.5% in December 2025 to 2.1% in June 2026. Total loan provisions decreased 0.4% YoY and 20.1% QoQ, explained by the specific case of the commercial portfolio, which was reversed in 2Q26. With that, the non-performing loan coverage ratio, including additional provisions, reached 107.6% in June 2026, and the expected loss ratio (loan loss provisions divided by total loans) increased to 3.3%. Significant rainfall has been recorded in various parts of the country during July, particularly in the Atacama and Coquimbo regions, where unusually high levels for this time of year have been observed. Management is continuously monitoring the evolution of these events and their potential effects on client activity and the various 45
business segments. In this regard, no material impacts on the loan portfolio or significant changes in the Bank's main risk and asset quality indicators are anticipated. Furthermore, this rainfall has contributed to the recovery of reservoirs and water reserves in several regions of the country, especially in the north, strengthening the future availability of water resources for economic activities dependent on this resource. The Bank will continue to assess the evolving situation and its potential impact on economic activity and specific productive sectors, maintaining prudent and timely management of associated risks.

Market risk There are four main market risks that can affect the Bank: exchange rate, inflation, interest rate, and liquidity. Their measurement and control are the responsibility of the Market Risk Management team, which is part of the Risk Division. Limits are approved by the various committees in charge, primarily the Market Committee and the Assets and Liabilities Committee (ALCO). The main market risks are also reviewed by the Integrated Risk Committee. The Financial and Capital Management areas, as part of the Financial Division, have the following functions, which are supervised and controlled by the ALCO and the Risk Management: • Optimizing the cost of liabilities by seeking the most efficient financing strategies, including the issuance of bonds and bank lines of credit. • Manage short- and long-term regulatory liquidity limits. • Inflation risk management and exposure. • Manage local and foreign currency exchange rate risk. • Capital adequacy and requirements. Liquidity risk The Financial Management area manages liquidity risk using a portfolio of liquid assets to ensure the Bank always maintains sufficient liquidity to cover short-term fluctuations and long-term financing, in compliance with internal regulatory liquidity requirements. The Financial Management Department receives information from all business units regarding the liquidity profile of their financial assets and liabilities, as well as a breakdown of other projected cash flows from future business activities. Based on this information, the area maintains a portfolio of short-term liquid assets, primarily consisting of liquid investments, loans, and advances to other banks, to ensure the Bank has sufficient liquidity. The liquidity needs of the business units are met through short-term transfers from Financial Management to cover short-term fluctuations and long-term financing to address all structural liquidity requirements. The Bank monitors its liquidity position daily, determining future cash inflows and outflows. Additionally, stress tests are conducted at the end of each month, using a variety of scenarios that encompass both normal market conditions and market fluctuations. Liquidity policies and procedures are subject to review and approval by the Bank's Board of Directors. Periodic reports are generated by the Market Risk Department, detailing the liquidity position of the Bank and its subsidiaries, including exceptions and corrective measures taken. These reports are submitted periodically to the ALCO for review. The Bank obtains demand and time deposits from its customer base, while the Finance Department obtains funding from correspondent banks, debt instruments, commercial paper, and wholesale time deposits. Although most obligations to banks and debt instruments mature in more than one year, customer and wholesale deposits tend to have shorter maturities, with a large proportion payable within 90 days. The short-term nature of these deposits increases the Bank's liquidity risk, and therefore, the Bank actively manages this risk through continuous monitoring of market trends and pricing management. 47
High-quality liquid assets High-quality liquid assets (HQLAs) are an essential component of liquidity risk management. They consist of balance sheet assets, primarily composed of financial investments that are not pledged as collateral, have low credit risk, and have a deep secondary market. According to Basel III standards, these assets are divided into three tiers, with Tier 1 assets being the most liquid and Tier 3 assets the least liquid. As of June 30, 2026, the Bank's HQLA amounted to $8,446,542 million and corresponded mainly to Level 1 liquid assets, composed mainly of bonds of the Republic of Chile, Central Bank of Chile and United States Treasury. Liquid Assets (Consolidated Ch$ million) Tier 1: Available, 1,697,584 Tier 1: Fixed Income, 6,746,426 Tier 2: Fixed Income, 2,532 Regarding liquidity, the main metrics managed by the Bank's Finance Division are the following: 1. Liquidity Coverage Ratio (LCR). 2. Net stable financing ratio (NSFR). LCR The Liquidity Coverage Ratio (LCR) measures the percentage of liquid assets relative to net cash outflows. This indicator is required by Basel III standards and provides a sustainable maturity structure for assets and liabilities, enabling banks to maintain a stable funding profile relative to their operations. As of June 30, 2026, this indicator for Banco Santander Chile stood at 177.1% above the minimum (100%). This reflects the conservative liquidity requirements established by the board of directors through the ALCO committee. 48

As of June 30, 2026, the NSFR stood at 118.2%.

To manage this risk, Banco Santander Chile conducts a sensitivity analysis regarding both local and foreign currencies. Through simulations, limits are set on the maximum potential loss that interest rate movements could have on capital and net financial income budgeted for the year. 49

Due to the rules established by the Assets and Liabilities Committee (ALCO), the Bank should not have significant exposure to foreign currencies; therefore, all exchange rate risk is included in the trading portfolio and is measured and controlled using Value at Risk (VaR) limits. The table below shows the evolution of the Bank's consolidated VaR for the trading portfolio, which includes foreign exchange risk and interest rate risk.

Risk of inflation The Bank holds assets and liabilities that are adjusted according to the variation of the Unidad de Fomento (UF). Generally, the Bank has more assets than liabilities denominated in UF, and therefore, moderate increases in inflation have a positive effect on adjustment income, while a decrease in the value of the UF negatively affects the Bank's margin. To manage this risk, the ALCO establishes a set of limits on the difference between assets and liabilities denominated in UF as a percentage of interest-bearing assets.
