REVIEW REPORT OF THE INDEPENDENT AUDITOR (A free translation from the original in Spanish) Santiago, October 25, 2023 To the Shareholders and Directors of Banco Itaú Chile Results of the review of the interim consolidated financial information We have reviewed the accompanying interim consolidated financial statements of Banco Itaú Chile and its subsidiaries, which comprise the interim consolidated statement of financial position as of September 30, 2023, and the corresponding interim consolidated statements of income and of other comprehensive income for the three-month and nine-month periods ended September 30, 2023 and 2022 and the corresponding interim consolidated statements of cash flows and changes in equity for the nine-month periods then ended, and the corresponding notes to the interim consolidated financial statements (jointly referred to as interim consolidated financial information). Based on our reviews, we are not aware of any significant changes that should be made to the interim consolidated financial information for it to be in accordance with accounting standards and instructions issued by the Financial Market Commission. Basis for the results of the review We conducted our review in accordance with the generally accepted auditing standards in Chile applicable to reviews of interim financial information. A review of the information Intermediate financial management consists mainly of applying analytical procedures and making inquiries of the persons responsible for accounting and financial matters. A review of interim financial information is substantially smaller in scope than an audit performed in accordance with generally accepted auditing standards in Chile, whose objective is the expression of an opinion on the interim financial information as a whole. Therefore, we do not express such an opinion. Pursuant to the relevant ethical requirements for our review, we are required to be independent of Banco Itaú Chile and its subsidiaries and to comply with other ethical responsibilities in accordance with such requirements. We believe that the results of the review procedures provide us with a reasonable basis for our conclusion. Management’s responsibility for the interim consolidated financial information Management of Banco Itaú Chile is responsible for the preparation and fair presentation of the interim consolidated financial information in accordance with accounting standards and instructions issued by the Financial Market Commission. This responsibility includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of interim consolidated financial information that is free from material misstatement, whether due to fraud or error.

Santiago, October 25, 2023 Banco Itaú Chile 2 Other matters – Statement of financial position as of December 31, 2022 On February 22, 2023, we expressed an unmodified audit opinion on the consolidated financial statements as of December 31, 2022 and 2021 of Banco Itaú Chile and its subsidiaries, which comprise the consolidated statement of financial position as of December 31, 2022 set forth in the accompanying interim consolidated financial statements, and the notes thereto.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 10 Note 2 - Summary of Significant Accounting Policies a) Accounting Year The Interim Consolidated Financial Statements are referred as of September 30, 2023 and December 31, 2022 and cover the three and nine months periods ended as of September 30, 2023 and 2022. b) Basis of preparation of the Consolidated Financial Statements These Interim Consolidated Financial Statements have been prepared in accordance with the Banking Compendium of Accounting Standards (here in after “the compendium”) issued by the CMF, and in force since January 1, 2022, Banks must use the accounting criteria set forth in the compendium and in everything that is not dealt with by it and does not contradict its instructions, they must adhere to International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB), If there are discrepancies between IFRS and the accounting criteria set forth in the compendium, the latter will prevail. Likewise, these Interim Consolidated Financial Statements in connection with the application of IAS 34 "Interim Financial Reporting", are prepared mainly with the intention of updating the content of the last Annual Consolidated Financial Statements, emphasizing new activities, events and circumstances that occurred during the three and nine months periods ended September 30, subsequent to year-end, and not duplicating the information previously published in the last Consolidated Financial Statements. These Interim Consolidated Financial Statements, by express provisions in Chapter C2, must include all the notes that apply to the annual financial statements in accordance with Chapter C1, plus additional requirements related to the disclosures of components of the Interim Consolidated Statements of Income for the period. Notwithstanding the foregoing, for a correct understanding of the information included in these Interim Consolidated Financial Statements, they should be read together with the annual Consolidated Financial Statements for the immediately preceding annual period (information available at www.itau.cl). The notes to these Interim Consolidated Financial Statements contain additional information to that presented in the Interim Consolidated Statements of Financial Position, the Interim Consolidated Statements of Income for the period, the Interim Consolidated Statements of Other Comprehensive Income for the period, the Interim Consolidated Statements of Changes in Equity for the period and the Interim Consolidated Statements of Cash Flows for the period. On them descriptive and disaggregated information is presented.

These Interim Consolidated Financial Statements as of September 30, 2023 and 2022 have not been audited. c) Consolidation criteria The same accounting policies, presentation and calculation methods applied in these Interim Consolidated Financial Statements were used in the preparation of the separate Financial Statements of Banco Itaú Chile and subsidiaries (hereinafter "Group" or the "Bank"), corresponding to the balances as of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 and include the adjustments and reclassifications necessary to standardize the accounting policies and valuation criteria applied by the Bank, in accordance with the standards established by the compendium.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 11 Note 2 - Summary of Significant Accounting Policies, continued Assets, liabilities, income, and results of operations of subsidiaries, net of consolidation adjustments, represent 17%, 19%, 20% y 11% respectively, of total consolidated assets, liabilities, income, and operating results as of September 30, 2023 (15% and 17% as of December 31, 2022, of total assets and liabilities; and 21% and 9% as of September 30, 2022, respectively). (i) Controlled entities The Bank, regardless of the nature of its involvement with an entity (the investee), shall determine whether it is a parent by assessing whether it controls the investee. The Bank controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Thus, the Bank controls an investee if and only if has all the following: 1) Power over the investee, which is related to the existing rights that give the Bank the current ability to direct the relevant activities, these being those that significantly affect the investee’s returns; 2) Exposure, or rights, to variable returns from its involvement with the investee; 3) Ability to use its power over the investee to affect the amount of the Bank's returns. When the Bank has less than a majority of the voting rights over an investee, but such voting rights are sufficient to have the actual ability to direct the relevant activities, then it will be concluded that the Bank has control over the investee. The Bank considers all relevant factors and circumstances when assessing if the voting rights are sufficient to obtain control, these include: x The amount of voting rights held by the Bank in relation to the amount and dispersion of those held by other vote holders. x Potential voting rights held by the Bank, other voting holders or other parties. x Rights that arise from other contractual agreements. x Any additional facts and circumstances that indicate that the Bank has, or does not have, the current ability to direct the relevant activities at the time those decisions need to be made, including the patterns of voting behavior in previous shareholders meetings. The Bank reassesses whether or not it has control over an investee when facts and circumstances indicate that there are changes in one or more of the control elements listed above. The Interim Financial Statements of the controlled companies are consolidated with those of the bank through the global integration method (line by line). In accordance with this method, all balances and transactions between consolidated companies are eliminated through the consolidation process. Therefore, the Interim Consolidated Financial Statements refer to assets, liabilities, equity, income, expenses, and cash flows of the parent and its subsidiaries presented as if they were a single economic entity. The Bank prepares ther Interim Consolidated Financial Statements using uniform accounting policies for transactions and other events that, being similar, have occurred in similar circumstances.

(10) On July 7, 2023, Itaú Corredores de Seguros S.A modifies its legal statute turning from a public company (S.A.) to a private limited company. (ii) Associated entities and/or business support Associated entities are those over which the Bank has significant influence; although not control or joint control. If the Bank holds, directly or indirectly (e.g. through subsidiaries), 20% or more of the voting power of the investee, it is presumed that the Bank has significant influence, unless it can be clearly demonstrated that this is not the case, and subsequently increased or decreased to recognize either the Bank's proportional share in the net profit or loss of the associate and other movements recognized in its equity. The lower value arising from the acquisition of an associate is included in the book value of the investment net of any accumulated impairment loss. Other factors considered to determine the significant influence on an entity are the representations in the Board of Directors and the existence of material transactions. The existence of these factors could determine the existence of significant influence on an entity, despite having a participation of less than 20% of the shares with the right to vote.

Credit and debit card services Santiago, Chile 8.7188 8.7188 Combanc S.A High-value payment clearing house Santiago, Chile 9.8114 9.8114 Imerc OTC S.A Administration of financial instrument clearing and settlement systems Santiago, Chile 8.6602 8.6602 (iii) Investments in other companies Investments in other companies, represented by shares or rights in other companies, are those in which the Bank has neither control nor significant influence. These equity instruments must be measured in compliance with IFRS 9, at their fair value; however, equity instruments that are neither held for trading and on which the equity method is not applied for investments in companies with significant influence (“associates” or “joint ventures”) according to IAS 28, may be recorded after their initial recognition and irrevocably at fair value, with variations recognized in Interim Statements of Other Comprehensive Income instead of as “Non-trading financial assets mandatorily at fair value through profit or loss”. Dividends received from these investments are recorded in "Income (loss) from investments in companies" in the Interim Consolidated Statement of Income. These instruments are not subject to the impairment model of IFRS 9. (iv) Funds management, trust business and other related businesses The Bank and its subsidiaries manage assets held in publicly offered investment funds and other investment vehicles on behalf of investors and receive market-rate compensation for providing this type of services. Managed funds belong to third parties and, therefore, are not included in the Interim Consolidated Statement of Financial Position. The Bank provides trust commissions and other fiduciary services that result in the participation or investment of assets by clients. Assets held in a fiduciary activity are not reported in the Interim Consolidated Financial Statements, since they are not Bank assets and there is no control over them. Contingencies and commitments arising from this activity are disclosed in Note 29 Contingencies and Commitments, letter d), related to Responsibilities recorded in off-balance-sheet accounts. In accordance with IFRS 10 “Consolidated Financial Statements” for consolidation purposes, the role of the Bank and its subsidiaries with respect to the managed funds must be evaluated to determine whether it is acting as Agent or Principal. According to this standard, an Agent is a party primarily engaged in acting on behalf and for the benefit of another party or parties (the Principal or Principals) and, therefore, it does not control the investee when it exercises decision-making authority. This evaluation must take into account the following aspects:

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 14 Note 2 - Summary of Significant Accounting Policies, continued x Scope of its decision-making authority over the investee. x Rights held by other parties. x The remuneration to which it is entitled to in accordance with the remuneration agreements.. x Decision-maker’s exposure to variability of returns from other interests that it holds in the investee. The Bank does not control or consolidate any trusts or other entities related to this type of business. The Bank manages the funds on behalf and for the benefit of investors, acting solely as an Agent. The assets managed by the Bank and its subsidiaries are owned by third parties. Under this category, and in accordance with the aforementioned standard, they do not control the assets when they exercise their decision-making authority. Therefore, as of September 30, 2023 and December 31, 2022 they act as Agents and, therefore, none of these investment vehicles is consolidated. d) Non-controlling interest Non-controlling interest represents the portion of net income and net assets which the Bank does not own, either directly or indirectly. It is presented as “Attributable to non-controlling interest” separately in the Interim Consolidated Statement of Income, and separately from equity in the Consolidated Other Comprehensive Income. Additionally, the non-controlling interests in the Interim Consolidated Statements of Financial Position will be presented, within the equity under item "Non-controlling interest", separately from the equity attributable to owners of the Bank. Changes in the ownership interest of a parent in a subsidiary that do not result in a loss of control are equity transactions (i.e., transactions with owners in their capacity as owners). The Bank attributes the result of the year and each component of other comprehensive income to the owners of the Bank and to the non-controlling interests. The Bank also attributes the total integral result to the owners of the Bank and to the non-controlling interests even if the results of the non-controlling interests give rise to a debit balance. e) Business combinations, Goodwill and Intangible Assets Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the sum of the consideration transferred, measured at its fair value at the acquisition date, and the amount of any non-controlling interest in the acquiree. For each business combination, the acquirer measures the non-controlling interest in the acquiree either at fair value or at the share, under the equity method, of the identifiable net assets acquired. Acquisition costs incurred are expensed and included in administrative expenses. When Banco Itaú Chile and its subsidiaries (the Group) acquires a business, evaluates the identifiable assets acquired and liabilities assumed to determine proper classification and designation based on contractual conditions, economic circumstances, and other relevant conditions as of the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree and identification of intangible assets.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 15 Note 2 - Summary of Significant Accounting Policies, continued Goodwill, defined as the difference between the consideration transferred and the amount recognized for the non-controlling interest in the net identifiable assets acquired and liabilities assumed, is measured initially at cost. If this consideration is less than the fair value of the net assets of the acquired subsidiary, the difference is recognized directly in profit or loss as of the acquisition date. While intangible assets are initially recorded at the value assigned to the identifiable asset in the business combination. After initial recognition, both Goodwill and any identifiable or non-identifiable intangible assets are measured at cost less any accumulated impairment losses. Goodwill acquired in a business combination is assigned, from the date of acquisition, to each of the Group's cash generating units (CGU) that are expected to benefit from the combination, independently of whether other assets or liabilities of the acquiree are assigned to those units. When goodwill is allocated to a CGU and an operation within that unit is sold, the goodwill associated with that operation is included in the carrying amount of the operation sold when determining the gain or loss on disposal. Goodwill that is derecognized under such circumstances is measured on the basis of the relative values of the operation disposed of and the retained portion of the CGU. f) Common control transaction A common control transaction is a transfer of assets or an exchange of equity interests among entities under the same parent’s control. A common control transaction has no effect on the parent’s consolidated financial statements. Net assets are derecognized by the transferor and recognized by the transferee at their carrying amount. Any difference between the value of the item transferred or received and the carrying amount of the net assets is recognized in equity in the separate financial statements of the transferring and receiving entities and eliminated on consolidation. g) Functional and presentation currency The Bank has defined as its functional and presentation currency the Chilean peso, which is the currency of the primary economic environment in which the Bank operates and the currency that influences its costs and revenue structure. Therefore, all balances and transactions denominated in currencies other than the Chilean peso are treated as "foreign currency". The Bank translates accounting records of its subsidiaries in New York and in Colombia into Chilean pesos from US dollars and Colombian pesos, respectively, in accordance with instructions established by the CMF, which are consistent with IAS 21 "Effects of the variations in the exchange rates of the foreign currency". All amounts in the Interim Consolidated Statements of Income, Interim Consolidated Statements of Other Comprehensive Income and the Interim Consolidated Statement of Financial Position are translated into Chilean pesos according to the exchange rate indicated in letter g) below. None of the markets in which Banco Itaú Chile and subsidiaries operate qualify as a hyperinflationary economy.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 16 Note 2 - Summary of Significant Accounting Policies, continued h) Foreign currency Transactions in foreign currency are initially recorded by the Bank entities at the exchange rates of their respective functional currencies at the date these transactions first meet the conditions for their recognition. Monetary assets and liabilities denominated in foreign currency are converted at the closing exchange rate of the functional currency in force at the closing date of the reporting period. All differences arising from the settlement or conversion of monetary items are recognized in the results, except for those that correspond to the monetary items that are part of the hedge of a net investment, at which time the cumulative difference in equity is reclassified to profit and loss (settlement). Tax effects attributable to the exchange differences on such monetary items are also recorded in Iterim Consolidated Other Comprehensive Income. Non-monetary items in foreign currency, which are measured in terms of historical cost, are converted using the exchange rate on the date of the transaction. Non-monetary items that are measured at their fair value in foreign currency are translated using the exchange rates on the date on which that fair value is measured. Gains or losses arising from the translation of non-monetary items measured at their fair value are recognized based on how the gains and losses arising from the change in fair value are recognized in Interim Consolidated Statements of Other Comprehensive Income or in Interim Consolidated Statements of Income, in accordance with IAS 21. The Bank grants loans and receives deposits in amounts denominated in foreign currency, mainly in US dollars and Colombian pesos. The balances of the Financial Statements of the consolidated entities whose functional currency is different from the Chilean peso are converted to the presentation currency, according to the following: x Assets and liabilities, by using exchange rates as of the date of the Interim Consolidated Financial Statements. x Income and expenses and cash flows, by using the exchange rates as of the date of each transaction. Exchange differences arising from translating balances in functional currencies of the consolidated entities other than Chilean pesos into Chilean pesos, are recorded as "Exchange differences" in Equity under the line item "Valuation accounts", until the meet the derecognition criteria for the Interim Consolidated Statement of Financial Position, and is subsequently recorded in profit or loss. The net amount of foreign exchange gains and losses includes the recognition of the effects of changes in the exchange rate over assets and liabilities denominated in foreign currencies and gains and losses arising from exchange rate changes affecting current and future transactions (highly probable transactions) entered into by the Bank. Assets and liabilities in foreign currencies are shown at their equivalent amount in pesos, calculated using the exchange rate of $891.33 per US$1 (US dollar) as of September 30, 2023 ($854.31 as of December 31, 2022) and the exchange rate of $0.2205 per COP$1 (Colombian peso) as of September 30, 2023 ($0.1761 as of December 31, 2022).

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 17 Note 2 - Summary of Significant Accounting Policies, continued The Iterim Financial Statements of the New York branch, as well as the Colombian subsidiaries, have been translated using these exchange rates for consolidation purposes, in accordance with IAS 21, related to the valuation of investments abroad in countries with stable economy. i) Use of estimates and judgments The preparation of the Interim Consolidated Financial Statements requires Bank’s management to make estimates, judgments and assumptions that affect the application of the accounting policies and the reported balances of assets and liabilities, disclosures of contingencies with respect to assets and liabilities as of the date of the Interim Consolidated Financial Statements, as well as income and expenses during the year. Actual results may differ from these estimates. Estimates and relevant assumptions are regularly reviewed by Management in order to properly measure some assets, liabilities, income, and expenses. Accounting estimates changes due to reviews are recognized in the year in which the estimate is reviewed and in any future year affected. In certain cases, CMF rules and International Financial Reporting Standards require that assets and liabilities be recorded or disclosed at their fair values. Fair value is 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. When market prices in active markets are available, they have been used as a basis for valuation. When market prices in active markets are not available, the Bank has estimated those values as values based on the best available information, including the use of modeling and other valuation techniques. The Bank has established allowances to cover possible credit losses in accordance with the compendium criteria. These criteria require that, in order to estimate allowances, they be evaluated regularly, taking into account factors such as changes in the nature and size of the loan portfolio, trends in the expected portfolio, credit quality and economic conditions that may affect the payment capacity of the debtors. Changes in allowances for loan losses are reflected as "Provision for loan losses" in the Interim Consolidated Statement of Income for the period. Loans are charged-off when the Bank’s management determines that the loan or a portion cannot be collected, in accordance with the compendium, as stated in chapter B-2 "Impaired loans and charge-offs". Charge offs are recorded as a reduction of the allowance for loan losses. In particular, information on most significant areas of estimate due to uncertainties and critical judgments in the application of accounting policies that have the most important effect on the amounts recorded in the Interim Consolidated Financial Statements are the following: x Allowances for loan losses (Notes 13 and 41). x Current taxes and deferred taxes (Note 18). x Provision for contingencies (Note 24). x Provision for dividends, interest payments and repricing of issued regulatory capital financial instruments (Note 25). x Special provisions for loan loss risk (Note 26). x Contingencies and commitments (Note 29).

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 18 Note 2 - Summary of Significant Accounting Policies, continued x Fair value of financial assets and liabilities (Note 44). x Impairment losses on certain assets, including Goodwill (Notes 13, 15, 16, 17, 40 and 41). During the three and nine months periods ended as of September 30, 2023, there have been no significant changes in estimates (see Notes 40 and 41). j) Operating segments The Bank provides financial information for each operating segment in conformity with IFRS 8 “Operating Segments” in order to disclose information that enables Interim Consolidated Financial Statement users to evaluate the nature and financial effects of the business activities in which the Bank engages and the economic environments in which it operates and to allow them to: x Better understand the Bank’s performance. x Better evaluate its future cash flow projections. x Form better opinions regarding the Bank as a whole. To comply with IFRS 8, Banco Itaú Chile identifies operating segments (Chile and Colombia) used by the Executive Committee to analyze and make decisions regarding operating, financing and investment matters, based on the following elements: (i) The nature of the products and services; (ii) The nature of the processes; (iii) The type or class of customer for their products and services; (iv) The methods used to distribute their products or provide their services; and (v) If applicable, the nature of the regulatory environment, for example, banking, insurance or public utilities. The Executive Committee manages these segments using an in-house system of internal profitability reports and reviews its segments on the basis of the operating results and uses efficiency, profitability and other indicators to evaluate performance and allocate resources. The Bank has also included geographic disclosures on its operations in New York and Colombia. More information on each segment is presented in Note 6 Reporting Segments. k) Operations with Repurchase and Resale Agreements Transactions with resale agreements are entered into as a form of investment. Under these agreements, financial instruments are purchased, which are included as assets under "Rights under resale agreements and securities lending agreements", and are accounted for at amortized cost using the effective interest rate of the agreement. There are also sales transactions with a repurchase agreement as a form of financing. In this regard, investments that are sold under a repurchase obligation and that serve as collateral for the loan, are part of the investment items "Financial assets held for trading at fair value through profit or loss", "Financial assets at fair value through other comprehensive income" or "Financial assets at amortized cost".

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 19 Note 2 - Summary of Significant Accounting Policies, continued The obligation to repurchase the investment is classified in Liabilities under "Obligations under repurchase agreements and securities lending transactions" and recognized in financial liabilities at amortized cost, recognizing accrued interest and indexation at the closing date or “Financial assets at amortized cost”. The obligation to repurchase the investment is classified as a liability under "Repurchase agreements and securities loans" and recorded in financial liabilities at amortized cost, recognizing accrued interest and inflation-indexation at the closing date. The Bank applies IFRS 9 for determining the impairment of its financial assets carried at amortized cost, except for assets classified under the compendium as "Interbank Loans", "Loans and receivables from customers and contingent loans" whose impairment determination follows the guidelines established in Chapters B1, B2 and B3 of the compendium. See Note 13 "Financial assets at amortized cost" and Note 41 "Credit loss expenses". l) Classifications of Financial Instruments (i) Classification of Financial Assets The Bank clasifies its Financial Assets under the following category as established by IFRS 9: x Measured at amortized cost, x Measured at fair value through other comprehensive income and x Measured at fair value through profit or loss x And those that by management's decision are irrevocably measured at fair value through other comprehensive income. The classification of financial instruments into an amortized cost or fair value category depends on the business model with which the entity manages the assets and the contractual characteristics of the cash flows, commonly referred to as the "Solely Payments of Principal and Interest" approach (hereinafter "SPPI"). The business model valuation should reflect how the Bank manages groups of financial assets and is not dependent on the intent for an individual instrument.Therefore, in each Interim Consolidated Financial Statement there are different business models for managing assets. In determining the business model, the following are taken into account: x How the performance of the business model (and the assets that are part of the business model) is evaluated and reported to the entity's key personnel. x The risks and the way in which risks that affect the performance of the business model are managed. x How business model managers are remunerated.The frequency, amount and timing of sales in prior periods, the reasons for such sales and expectations regarding future sales.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 20 Note 2 - Summary of Significant Accounting Policies, continued With regard to the assessment of contractual cash flows, it determines whether the cash flows of the financial asset meet the SPPI criterion, i.e. whether the contractual terms of the financial asset give rise, on specific dates, to cash flows that are solely payments of principal and interest. Principal is the fair value of the financial asset at initial recognition, and interest is the consideration for the time value of money, the credit riskassociated with the principal outstanding and may also include liquidity risk, administrative cost and profit margin. For the classification, the Bank performs the SPPI test, which evaluates the contractual term to identify whether it meets the SPPI criteria, and whether the contract is a basic loan agreement. The Bank applies its judgment and considers relevant factors such as the currency in which the financial asset is denominated and the year for which the interest rate is set. The Bank's business model represents how financial assets are managed to generate cash flows and does not depend on management's intent with respect to an individual instrument, but relates to a higher aggregate portfolio level, and is based on observable factors such as: risks affecting business model performance; how business managers are compensated; and how business model performance is evaluated and reported to management. In addition, the Bank's business model is not evaluated on an instrument-by-instrument basis, but at a higher aggregate portfolio level, and is based on observable factors such as: the performance of financial assets, the risk affecting performance, and the frequency, value and timing of sales, among others. In accordance with IFRS 9, the business models are: x Business model held for collection: financial assets that are held under a business model whose objective is to collect principal and interest flows over the life of the instrument and on which there are no significant unjustified sales and fair value is not a key element in the management of these assets and the contractual conditions give rise to cash flows on specific dates, which are only payments of principal and interest on the principal amount outstanding. In this sense, sales other than those related to an increase in credit risk, to manage credit concentration risk, or unforeseen financing needs (liquidity stress scenarios) are considered unjustified, and are not incompatible with a business model whose objective is to hold financial assets to collect the contractual cash flows. x Held to collect and sell: financial assets under this business model whose objective is achieved through the collection of principal and interest flows and the sale of such assets, with fair value being a key element in the management of these assets. This model involves a higher frequency and value of sales than the model. x Another business model: includes financial assets with the objective of realizing cash flows through the sale of the assets. The Bank makes decisions based on the assets’ fair values and manages the assets to realize those fair values.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 21 Note 2 - Summary of Significant Accounting Policies, continued Financial assets will only be reclassified when there is a change in the business model. In this case, all financial assets in that business model are reclassified. The change in the business model objective must be prior to the reclassification date. (ii) Classification of financial liabilities Financial liabilities are classified in the following categories: x Financial liabilities at amortized cost; x Financial liabilities held for trading (including derivatives): these are instruments that are recorded in this category when the Bank's objective is to generate profits through the realization of purchases and sales with these instruments; x Financial liabilities designated at fair value through profit or loss on initial recognition (fair value option). The Bank has the option to irrevocably designate, at the time of initial recognition, a financial liability as measured at fair value through profit or loss if the application of this criterion eliminates or significantly reduces inconsistencies in valuation or recognition, or if it is a group of financial liabilities, or a group of financial assets and liabilities, that is managed, and its performance evaluated, on a fair value basis in line with a risk management or investment strategy. (iii) Embedded derivatives in hybrid financial instruments Embedded derivatives in other financial instruments or in other host contracts are accounted for separately as financial derivatives contracts when the following criteria are met: 1) its risks and characteristics are not directly related with those of the host contract, 2) a separated instrument with same characteristics of the embedded derivative meets the derivative instrument definition, and 3) the host contract is not classified as “other financial assets (liabilities) at FVTPL” or as “trading instruments”. (iv) Reclassifications Reclassification of financial assets is required if, and only if, the objective of the Bank's business model for managing those financial assets changes. Financial liabilities cannot be reclassified. There are no reclassifications in these Interim Consolidated Financial Statements. II. Measurement of financial instruments (i) Initial measurement On initial recognition, financial assets and liabilities are measured at the transaction price, i.e. the fair value of the consideration given or received (IFRS 13). In the case of financial instruments that are not measured at fair value through profit or loss, transaction costs of financial assets and financial liabilities recorded at fair value are recorded in profit or loss.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 22 Note 2 - Summary of Significant Accounting Policies, continued (ii) Subsequent measurement - Financial assets After initial recognition, the Bank will measure a financial asset at: (a) Amortized cost Financial assets that are held in a business model to collect contractual cash flows and contain contractual terms that give rise on specified dates to cash flows that are SPPI are measured at amortized cost. The effective rate method is used in the calculation of the amortized cost of a financial asset or financial liability and in the allocation and recognition of interest income or interest expense in profit or loss for the relevant year. The effective interest rate (EIR) is the rate that exactly discounts estimated future cash payments or collection through the expected life of the financial asset or financial liability to the gross carrying amount of a financial asset or the amortized cost of a financial liability. The net impairment losses of the assets recorded in these items occurring in each year are determined in accordance with IFRS 9, except for assets classified under the compendium as "due from banks", "loans and receivables from customers and contingent loans" whose impairment determination follows the guidelines established in Chapters B1, B2 and B3 of the compendium. For purposes of recording the impairment loss, this is recorded under the caption "Provisions for credit risk due from banks and loans and accounts receivable from customers" and "Impairment for credit risk of other financial assets at amortized cost and financial assets at fair value through other comprehensive income" in the Interim Consolidated Statements of Income. See note 41 "Credit loss expense". (b) Fair value through other comprehensive income (FVTOCI) Financial assets that are debt instruments held in a business model that is achieved through the collection of contractual cash flows and sale, and that contain contractual terms that result on specified dates in cash flows that are SPPI, are measured at FVTOCI. They are subsequently remeasured at fair value and changes in fair value (except for those related to impairment, interest income and foreign exchange gains and losses) are recognized in other comprehensive income, until the assets are sold. At the time of disposal, gains and losses accumulated in other comprehensive income are recognized in the statement of income. On the other hand, the net impairment losses on financial assets at fair value through other comprehensive income occurring during the period are recorded under the item "Impairment due to credit risk of other financial assets at amortized cost and financial assets at fair value through other comprehensive income” in the Interim Consolidated Statements of Income. (See Note 41). Interest income on these instruments is recorded in the consolidated income and loss account for that year. Exchange differences are recorded in "Changes, indexation and accounting hedge of foreign currencies" in the Interim Consolidated Statements of Income.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 23 Note 2 - Summary of Significant Accounting Policies, continued (c) Fair value through profit or loss (FVTPL) The caption "Financial assets held for trading at fair value through profit or loss" includes financial assets whose business model is intended to generate profits through the realization of purchases and sales or to generate results in the short term. Financial assets recorded under "Financial assets not held for trading mandatorily measured at fair value through profit or loss" are assigned to a business model whose objective is achieved by obtaining contractual cash flows and/or selling financial assets but the contractual cash flows have not met the conditions of the SPPI test. Financial assets are classified under "Financial assets designated at fair value through profit or loss" only when such designation eliminates or significantly reduces the inconsistency in valuation or recognition that would arise from valuing or recognizing the assets on a different basis. The assets recorded in these captions of the Interim Consolidated Statements of Financial Position are valued after their acquisition at fair value and the changes in their value (gains or losses) are recorded, at their net amount, in the items "Financial income or loss from financial assets and liabilities held for trading" and "Financial income or loss from financial assets not held for trading mandatorily valued at fair value through profit or loss" of the Consolidated Statements of Income. Changes arising from exchange differences are recorded in "Changes, indexation and accounting hedge of foreign currencies" in the Interim Consolidated Statements of Income. (d) Financial assets not held for trading mandatorily measured at fair value through profit or loss Under this item, they are allocated to a business model the objective of which is achieved by obtaining contractual cash flows and/or by selling financial assets, but where the contractual cash flows have not met the SPPI test conditions. The assets recorded under this item of the Interim Consolidated Statement of Financial Position are measured subsequently to their acquisition at fair value and their market value variations are recorded, at their net amount, under “Financial income (loss), net”. (e) Equity instruments For certain equity instruments, the Bank may make an irrevocable election to present subsequent changes in the fair value of the instrument in other comprehensive income, except for dividend income which is recognized in profit or loss. Gains or losses on derecognition of these equity instruments are not transferred to income. These instruments are not subject to the impairment model of IFRS 9. (iii) Subsequent measurement - Financial liabilities After initial recognition, the Bank will measure a financial liability at amortized cost, except for derivatives that are measured at fair value through profit or loss.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 24 Note 2 - Summary of Significant Accounting Policies, continued III. Derecognition of financial assets and liabilities Financial assets are derecognized when, and only when: x The contractual rights to the cash flows from the financial asset expire, or x The Bank transfers substantially all the risks and rewards of ownership of the financial asset, and therefore the Bank derecognizes the financial asset and separately recognizes the rights and obligations created or retained in the transfer. In some cases, the Bank enters into transactions whereby it retains the contractual rights to receive the cash flows from the financial asset, but assumes a contractual obligation to pay the cash flows in an arrangement that meets all the required conditions, that is, the Bank only transfers the cash flows collected. amounts of the original assets, the original assets are prohibited from being sold or pledged, and the Bank has an obligation to send the cash flows collected without significant delay. When a financial asset is sold and the Bank simultaneously agrees to repurchase it (or an asset that is substantially the same) at a fixed price on a future date, the Bank continues to recognize the financial asset in its entirety in the Interim Statements of Financial position because it retains substantially all the risks and rewards of ownership. The cash consideration received is recognized as a financial asset and a financial liability is recognized for the obligation to pay the repurchase price. Financial liabilities are derecognized when, and only when, they are extinguished, canceled or mature. Derecognition due to substantial modification of terms and conditions The Bank derecognizes a financial asset, such as a loan to a customer, when the terms and conditions have been renegotiated to the extent that it has essentially become a new asset, with the difference recognized as a gain or loss on derecognition, to the extent that an impairment loss has not yet been recorded. A change in terms and conditions does not result in derecognition if it does not result in cash flows that are substantially different. Based on the change in cash flows discounted at the original Effective Interest Rate ("EIR"), the Bank records a gain or loss on modification, to the extent that an impairment loss has not yet been recorded. For financial liabilities, the Bank considers a substantial modification based on qualitative factors, and if it results in a difference between the adjusted discounted present value and the original carrying amount of the financial liability of ten percent or more. For financial assets, this assessment is based on qualitative factors.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 25 Note 2 - Summary of Significant Accounting Policies, continued IV. Renegotiated and modified loans The Bank in certain situations makes concessions or modifications to the original terms of loans in response to the borrower's financial difficulties, in lieu of taking possession or enforcing collection of collateral, or in some cases to renegotiate loans. The Bank considers a loan modified when such concessions are made as a result of the borrower's present or expected financial difficulties and the Bank would not have accepted them had the borrower been in good financial standing. Indicators of financial difficulties include covenant defaults and/or significant additional history identified by the Credit Risk area. Modification may involve extending payment terms and agreeing to new loan terms. It is the Bank's policy to monitor refinanced loans to help ensure that future payments are probable. If the modifications are substantial, the loan is written off, as explained in "III. Derecognition of financial assets and liabilities”. If the terms have been renegotiated without resulting in the derecognition of the loan, any impairment is measured using the original EIR calculated prior to the modification of the terms. The Bank also reassesses whether there has been a significant increase in credit risk and whether the assets should be classified in another credit risk portafolio. (As set out in section t). Derecognition decisions and classifications in the substandard and non-performing portfolios are determined on a case-by-case basis. If these procedures identify a loss related to a loan, it is disclosed and managed as a refinanced asset of the impaired non-performing portfolio until collected or paid. V. Contingent Credits The Bank provides standby loans (including letters of credit, foreign letters of credit and performance bonds) and loan commitments. Contingent loans and unused loan commitments are commitments under which, during the term of the commitment, the Bank is obligated to provide a loan with a pre-specified term to the customer. The face value of the contractual loan, when the agreed loan is on market terms, is not recorded in the Interim Statement of Financial Position. The related provision for expected credit loss is disclosed in Note 24 "Provisions for contingencies", letter b). VI. Offsetting Financial assets and financial liabilities are offset in the Interim Consolidated Statement of Financial Position only when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle them on a net basis, or to realize the asset and settle the liability simultaneously.

Derivatives and hedging activities The Bank has decided to continue to apply the hedge accounting requirements of IAS 39 when adopting IFRS 9. For presentation purposes, derivatives are presented according to their positive or negative fair value as assets or liabilities, respectively, and include trading and hedging instruments separately (see Notes 8 "Financial assets held for trading through profit or loss" and Note 12 "Financial derivative contracts for accounting hedges"). Hedging transactions The Bank uses financial derivatives for the following purposes: i. to sell to customers who request these instruments in the management of their market and credit risks. ii. to use these derivatives in managing the risks of the Bank's own positions and assets and liabilities of the Bank's entities ("hedging derivatives"); and iii. to obtain gains from changes in the price of these derivatives ("trading derivatives"). All financial derivatives that are not held for hedging purposes are accounted for as trading derivatives. A derivative qualifies for hedge accounting if all of the following conditions are met: i. The derivative hedges one of the following three types of risks to which the Bank is exposed: a) Changes in the value of assets and liabilities due to fluctuations, among others, in the interest rate and/or exchange rate to which the position or balance to be hedged is subject ("fair value hedge"); b) Changes in the estimated cash flows derived from financial assets and liabilities, and highly probable forecast transactions ("cash flow hedge"); c) The net investment in a foreign operation ("hedge of a net investment in a foreign operation"). ii. It is effective in offsetting the exposure inherent in the hedged item or position over the expected term of the hedge, which means that: a) At the trade date the hedge is expected, under normal conditions, to be highly effective ("prospective effectiveness"). b) There is sufficient evidence that the hedge was effective during the life of the hedged item or position ("retrospective effectiveness"). There must be adequate documentation evidencing the specific designation of the financial derivative to hedge certain balances or transactions and how this effective hedge was expected to be achieved and measured, provided that it is consistent with the Bank's own risk management.

For fair value hedges, gains or losses arising on both hedging instruments and hedged items (attributable to the type of risk being hedged) are included as "Financial income (loss) from Financial Asset and Liabilities for trading" in the Interim Consolidated Statement of Income. b. For fair value hedges of interest rate risk in a portfolio of financial instruments, gains or losses arising on measurement of the hedging instruments within "Interest income and expense", and other gains or losses due to changes in the fair value of the underlying hedged item (attributable to the hedged risk) are recorded in the Interim Consolidated Statement of Income (Loss) under "Net trading income (expense)". c. For cash flow hedges, the effective portion of the fair value of the hedging instrument is included as "Cash flow hedges" in the "Interim Statement of Other Comprehensive Income". d. The valuation differences of the hedging instrument corresponding to the ineffective portion of cash flow hedging transactions are recorded directly in the Interim Consolidated Statement of Income under "Net income (expense) from financial operations". If a derivative designated as a hedging instrument ceases to meet the conditions described above due to maturity, ineffectiveness or any other reason, the hedge accounting treatment is discontinued. When the "fair value hedge" is discontinued, the fair value adjustments to the carrying amount of the hedged item arising from the hedged risk are amortized to profit or loss as of that date, as appropriate. Sources of hedge ineffectiveness may arise from basis risk, including, but not limited to, discount rates used to calculate the fair value of derivatives, hedges using instruments with a fair value other than zero, and timing and notional differences between hedged items and hedging instruments. When cash flow hedges are discontinued, any cumulative gain or loss on the hedging instrument recognized in "Interim Statements Other Comprehensive Income" (from the year in which the hedge was effective) remains recorded in equity until the hedged transaction occurs, at which time it is recorded in the Interim Consolidated Statement of Income, unless the transaction is no longer expected to occur, in which case any cumulative gain or loss is recorded immediately in the Interim Consolidated Statement of Income.

Financial instruments, other than those measured at fair value through profit or loss, are initially recognized at fair value plus transaction costs. Subsequently, and at the end of each reporting year, financial instruments are valued in accordance with the following criteria: (i) Measurement of financial instruments Financial assets are measured at fair value, gross of any transaction costs that may be incurred in the course of a sale, except for loans and receivables from customers. In accordance with IFRS 13 "Fair value measurement", "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 between market participants at the measurement date. In measuring fair value, an entity shall take into account the characteristics of the asset or liability if market participants would take those characteristics into account in pricing the asset or liability at the measurement date. The fair value measurement assumes that the transaction to sell the asset or transfer the liability takes place: (a) in the main market for the asset or liability, or (b) in the absence of a main market, the most advantageous market for the asset or liability. Even if there is no observable market that provides pricing information in relation to the sale of an asset or transfer of a liability at the measurement date, the fair value measurement shall assume that the transaction takes place, considered from the perspective of a potential market participant who intends to maximize the value associated with the asset or liability. In using valuation techniques, the Bank shall maximize the use of relevant observable inputs and minimize the use of available unobservable inputs. If an asset or liability measured at fair value has a bid price and a ask price, the price within the bid-ask spread that is most representative of fair value in the circumstances is used to measure fair value, regardless of where the input is classified within the fair value hierarchy (i.e. Level 1, 2 or 3). IFRS 13 establishes a fair value hierarchy that classifies inputs to valuation techniques used to measure fair value into three levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1 inputs) and the lowest priority to unobservable inputs (Level 3 inputs). All derivatives are recorded in the Interim Consolidated Statements of Financial Position at the fair value described above. This value is compared to the valuation on the trade date. If the fair value is subsequently measured positive, it is recorded as an asset. If the fair value is subsequently measured negative, it is recorded as a liability. The fair value on the trade date is, unless there is evidence to the contrary, considered to be the transaction price.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 29 Note 2 - Summary of Significant Accounting Policies, continued Changes in the fair value of derivatives since the trade date are recorded in "Financiamial income (loss)" in the Interim Consolidated Statements of Income. Specifically, the fair value of financial derivatives included in portfolios of financial assets or liabilities held for trading is considered to be their daily quoted price. If, for exceptional reasons, the quoted price cannot be determined on a given date, the fair value is determined using methods similar to those used to measure over-the-counter derivatives. The fair value of OTC derivatives is the sum of the future cash flows resulting from the instrument, discounted to present value at the valuation date ("present value" or "theoretical close") using valuation techniques commonly used in financial markets: “net present value" (NPV) and option valuation models, among other methods. In addition, the fair value of derivatives includes the CVA and DVA adjustment, so that the fair value of each instrument includes the credit risk of its counterpart and the Bank's own risk. The credit valuation adjustment (CVA) is a valuation adjustment of OTC derivatives as a consequence of the risk associated with the credit exposure assumed by each counterpart. The CVA is calculated taking into account the potential exposure to each counterpart in each future year. The debit valuation adjustment (DVA) is a valuation adjustment similar to the CVA but, in this case, arises as a consequence of the Bank's own risk assumed by its counterparts in OTC derivatives. (ii) Valuation techniques Financial instruments at fair value, determined on the basis of quoted prices in active markets, include government debt securities, private sector debt securities, equity shares, short positions and fixed income securities issued. In cases where price quotations are not observable in available markets, the Bank's management determines the best estimate of the price that would be set by the market using its own internal models. In most cases, these models use data based on observable market parameters as significant inputs; however, for some financial instrument valuations, significant inputs are not observable in the market. To determine a value for these instruments, various techniques are used to make these estimates, including extrapolation of observable market data. The most reliable evidence of the fair value of a financial instrument at initial recognition is usually the transaction price; however, due to the unavailability of market information, the value of the instrument may be derived from other market transactions involving the same or similar instruments or may be measured using a valuation technique in which the inputs used include only observable market data, principally interest rates. The main techniques used as of September 30, 2023 and December 31, 2022 by the Bank's internal models to determine the fair value of financial instruments are as follows:

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 30 Note 2 - Summary of Significant Accounting Policies, continued i. The present value method is used in the valuation of financial instruments that allow static hedges (mainly forwards and swaps). The estimated future cash flows are discounted using interest rate curves of the related currencies. Interest rate curves are generally observable market data. ii. In the valuation of financial instruments requiring dynamic hedging (mainly structured options and other structured instruments), the Black-Scholes model is typically used. Where appropriate, observable market data is used to derive factors such as bid spread, exchange rates, volatility, correlation indicators and market liquidity. iii. In the valuation of certain financial instruments exposed 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 observable market data, including interest rate curves, volatilities, correlations and related exchange rates. The fair value of financial instruments calculated by the aforementioned internal models considers contractual terms and observable market data, including interest rates, credit risk, exchange rates, stock price, volatility and prepayments, among others. The Bank's management believes that its valuation models are not significantly subjective, as these methodologies can be adjusted and evaluated, as appropriate, through internal calculation of fair value and subsequent comparison with the related actively quoted price (See note 44). n) Revenue and expense recognition The following is a summary of the most significant criteria used by the Bank for the recognition of its revenues and expenses: (i) Interest income, interest expense and similar items Interest income, interest expense and similar items are recognized on an accrual basis using the effective interest rate method. However, when an operation is evaluated either individually or collectively, and as a result of such evaluation the placements are recognized in the impaired portfolio (the compendium Cap. B2 numeral 1 letter b), being debtors subject to group evaluation, includes all loans in the "Default Portfolio"; on the other hand, in the individual portfolio (defined as placements classified in categories B3 and B4 plus the default portfolio) and which are in arrears for 90 days or more in any of their installments, the recognition of income on the accrual basis is suspended. The suspension of revenue recognition on an accrual basis implies that, from the date on which it should be suspended in each case and until such loans are no longer impaired, the respective assets included in the Interim Statement of Financial Position will not be increased by interest, adjustments or commissions and no revenue for these items will be recognized in the Interim Consolidated Statement of Income, unless they are actually received. These standards only refer to the criteria for valuation and recognition of income for financial accounting information.

(ii) Dividends received Dividends received from investments in other companies are recognized on income when the right to receive them arises and are recorded in the item “Income from investments in companies”. (iii) Commissions, fees and similar items Income and expenses from commissions and fees are recognized in the Interim Consolidated Statement of Income using the criteria established in IFRS 15 "Revenue from contracts with customers", based on consideration of the terms of the contract with the customers, excluding amounts collected on behalf of third parties. Revenue is recognized when performance obligations are satisfied by transferring a promised good or service to a customer, which is evidenced by transferring control over an asset or the rendering of a service: Commissions recorded by the Bank correspond mainly to: x Line of credit and overdraft commissions: includes earned commissions during the year related to lines of credit granted and checking accounts overdrafts. x Guarantee and letters of credit fees: includes earned commissions during the year related to bank guarantees granted over actual or contingent obligations to third parties. x Credit card fees: includes earned and received commissions during the year related to credit and debit cards usage. x Accounts management fees: includes earned fees related to maintenance of checking accounts, savings accounts, and other accounts. x Collection and payment services fees: includes fee income related to collection services as well as payment services rendered by the Bank and its subsidiaries. x Brokerage and securities management fees: includes fee income related to financial assets brokerage and securities management and custody. x Insurance brokerage fees: includes insurance brokerage fees. x Other fee and commissions: includes income arising from currency exchange, financial advisory services, cashier checks issuance, placement of financial products and online banking services. Commission expenses include: x Cards transactions fees: includes credit and debit card transaction fees related to income generated in those transactions. x Securities transactions fees: includes fees related to custody of securities and securities brokerage. x Other fees and commissions: includes mainly expenses generated from online services.

(iv) Non-financial income and expenses They are recorded in accordance with IFRS 15, identifying the performance obligations, allocating the transaction price to separate performance obligations, and recognizing income when these are satisfied. (v) Loan arrangement fees Fees that arise from loans arrangement, opening accounts, study and information fees, they are accrued and recognized on a sistematic basis on the Consolidated Statement of Income throughout the life of the loan. In the case of arrangement fees, the portion corresponding to the related direct costs incurred in the formalization of such transactions are immediately recorded in the income statement. o) Impairment Assets are acquired or purchased based on the future economic benefits they produce. Consequently, impairment is recorded when the carrying amount of such assets is less than their recoverable amount. Assets are subject to impairment tests to adequately reflect the future economic benefits that the assets are capable of producing when used by the Bank. The Bank assesses the expected future credit losses ("ECL") associated with its financial instrument assets carried at amortized cost and FVTOCI, subject to the limitations defined in paragraph 5 of Chapter A-2 of the Compendium of Accounting Standards. The Bank recognizes a loss allowance for such losses at each reporting date. The measurement of ECL reflects: x An unbiased, probability-weighted amount determined by evaluating a range of possible outcomes; x The time value of money; and x Reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions. The Bank follows the criteria described below to assess impairment, when applicable: (i) Impairment of financial assets except "Interbank Loans", "Loans and receivables from customers and "Contingent loans". The Bank applies IFRS 9 to determine the impairment of its financial assets at amortized cost and at fair value through other comprehensive income, except for "Interbank Loans", "Loans and accounts receivable from customers" and "Contingent loans", whose impairment is determined by applying the provisions of Chapter B1, B2 and B3 of the compendium, for the rest of the assets the following is applicable.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 33 Note 2 - Summary of Significant Accounting Policies, continued IFRS 9 introduces the concept of "expected losses" which is developed in the credit risk model applied by the Bank. The "expected loss" impairment model is applied to financial assets measured at amortized cost, debt instruments measured at fair value through other comprehensive income, financial guarantee contracts and other commitments. All financial instruments measured at fair value through profit or loss are excluded from the impairment model. The standard classifies financial instruments into three categories, which depend on the evolution of their credit risk from the time of initial recognition, and which determine the calculation of their credit risk hedges. Stage 1: No significant increase in risk: "The allowance for losses on these financial instruments is calculated as the expected credit losses resulting from possible events of default within 12 months after the reporting date (12-month expected loss)." Stage 2: With significant increase in risk: "When the credit risk of a financial asset has increased significantly since initial recognition, the allowance for losses on that financial instrument is calculated as the expected credit loss over the entire life of the transaction. In other words, it is the expected credit losses resulting from all possible events of default during the expected life of the financial instrument". Stage 3: Impairment: "When there is objective evidence that the financial asset is impaired, it is transferred to this category in which the write-down for losses on that financial instrument is calculated, as in Stage 2, as the expected credit loss over the life of the asset." In cases in which the recovery of any recorded amount is considered remote, the asset is removed from the consolidated balance sheet, without prejudice to any actions that may be taken to attempt to collect the amount until the rights to receive it have been extinguished definitively, whether by expiration, forgiveness or other causes. The Bank takes into account reasonable and supportable information that is available without undue cost or effort and that may affect the credit risk of a financial instrument, including forward-looking information to determine a significant increase in credit risk since initial recognition. Forward-looking information includes past events, current conditions and expected or future economic conditions (macroeconomic data). Credit risk assessment and forward-looking information (including macroeconomic factors), includes quantitative and qualitative information based on the Bank's historical experience, examples include: x Financial or economic conditions that are expected to cause a significant change in the borrower's ability to meet its debt obligations. x An actual or expected downgrade of the borrower's internal credit rating or a decrease in the borrower's performance score. x An actual or expected significant change in the borrower's operating results. x Significant increases in credit risk on other financial instruments of the same borrower. x Significant changes in the value of the collateral backing the obligation or in the quality of third-party guarantees or credit enhancements. x Reductions in financial support from a parent entity or other subsidiary.

The Bank has considered that if contractual payments are more than 30 days past due, credit risk is considered to have increased significantly since the initial recognition of the credit, but this is not an absolute indicator. The Bank has not rebutted the IFRS 9 presumption of significant increase in risk ("SIR") or default. Regarding the use of present, past and future information required by the application of the expected loss approach described in IFRS 9, this requires the incorporation of present, past and future information for both the detection of significant increase in risk and the measurement of expected losses, which should be performed on a probability-weighted basis. When estimating expected losses, the standard does not require the identification of all possible scenarios. However, the probability of a loss event occurring and the probability of it not occurring must be considered, even if the possibility of a loss occurring is very low. To achieve this, the Bank evaluates the linear relationship between its estimated loss parameters (PI, PDI, and EAP) with the history and future forecasts of macroeconomic scenarios. Also, when there is no linear relationship between the different future economic scenarios and their associated expected losses, more than one future economic scenario should be used for the estimation. Expected losses are then derived from the following parameters: PI: estimate of the probability of default in each year. EAP: estimate of the exposure in the event of default in each future period, taking into account changes in exposure after the reference date of the Interim Financial Statements. PDI: estimated loss given default, as the difference between the contractual cash flows and those expected to be received, including collateral. For these purposes, the estimate considers the probability of execution of the guarantee, the time until possession and subsequent realization is reached, the expected cash flows and the acquisition and sale costs. CCF: Cash Conversion Factor, is the estimate made on off-balance sheet balances to determine the exposure subject to credit risk in the event of default. The expected credit losses calculated are based on the internal models developed for all portfolios within the scope of IFRS 9, except for those cases that are subject to individualized estimation. Internal models have been developed that take into account as sources of information the data provided by external rating agencies or others observed in the market, such as changes in bond yields, credit default swap quotes or any other public information on them.

If such indications exist, then the recoverable amount of the asset is estimated. The recoverable amount of an asset is the higher of fair value less costs to sell and value in use. That recoverable amount is determined for an individual asset, unless the asset does not generate cash flows that are substantially independent of the cash flows from other assets or group of assets. When the carrying amount of an asset exceeds its recoverable amount, the asset is considered impaired and its value is reduced to its recoverable amount. The recoverable amount is the higher of fair value less costs to sell and value in use. If we assess the value in use of an asset, the estimated cash flows are discounted to their present value by applying a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. The Bank shall assess at the end of each reporting period whether there is any indication that an impairment loss recognized in prior periods for an asset other than goodwill may no longer exist or may have decreased. If any such indication exists, the entity shall estimate the recoverable amount of that asset. In assessing whether there is any indication that an impairment loss recognized in prior periods for an asset other than goodwill may no longer exist or may have decreased, an entity shall consider, as a minimum, external sources of information (the asset’s value has increased significantly during the period; significant changes with a favorable effect on the entity have taken place during the period, or will take place in the near future, in the technological, market, economic or legal environment in which the entity operates or in the market to which the asset is dedicated; market interest rates or other market rates of return on investments have decreased during the period, and those decreases are likely to affect the discount rate used in calculating the asset’s value in use and increase the asset’s recoverable amount materially) and internal sources of information such as significant changes with a favorable effect on the entity have taken place during the period, or are expected to take place in the near future, in the extent to which, or manner in which, the asset is used or is expected to be used. These changes include costs incurred during the period to improve or enhance the asset’s performance or restructure the operation to which the asset belongs. In the case of goodwill and indefinite useful life intangible assets or not yet available for use, the recoverable amount is estimated annually, at year end. When impairment exists the carrying amount of the asset shall be reduced to its recoverable amount if, and only if, the recoverable amount of an asset is less than its carrying amount. This reduction is an impairment loss. The impairment loss is recognized immediately in income for the period, unless the asset is carried at its revalued value in accordance with another standard. Any impairment loss on revalued assets will be treated as a decrease in the revaluation made in accordance with that other standard. When the amount estimated for an impairment loss is greater than the carrying amount of the asset to which it relates, the Bank shall recognize a liability if, and only if, that is required by another standard. After the recognition of an impairment loss, the depreciation (amortization) charge for the asset shall be adjusted in future periods to allocate the asset’s revised carrying amount, less its residual value (if any), on a systematic basis over its remaining useful life.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 36 Note 2 - Summary of Significant Accounting Policies, continued If an impairment loss is recognized, any related deferred tax assets or liabilities are determined in accordance with IAS 12 “Income taxes” by comparing the revised carrying amount of the asset with its tax base. Impairment losses recognized in prior periods are tested at each reporting date for any indication that the loss has decreased or disappeared. An impairment loss is reversed only to the extent that the carrying amount of the asset does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. (iii) Goodwill Goodwill is tested annually in order to determine if impairment losses exist and whenever there is an indication that the carrying value may be impaired. The impairment of goodwill is determined by evaluating the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. An impairment loss is recognized when the recoverable amount of the CGU is less than its carrying amount. For the purpose of impairment testing, goodwill acquired in a business combination shall, from the acquisition date, be allocated to each of the acquirer’s cash-generating units, or groups of cash-generating units irrespective of whether other assets or liabilities of the acquiree are assigned to those units or groups of units. An impairment loss recognized for goodwill shall not be reversed in a subsequent years. According to IAS 36 “Impairment of assets” the annual impairment test for a cash-generating unit to which goodwill has been allocated or for intangible assets with indefinite useful lives may be performed at any time during an annual year, as long the test is performed at the same time every year. Different cash-generating units may be tested for impairment at different times. p) Fixed assets Items of fixed assets are measured at acquisition cost, net of accumulated depreciation and impairment, if any. In addition to the price paid to acquire each item, the cost also includes, where applicable, the capitalized cost. The capitalized cost includes expenses attributed directly to the asset acquisition and any other costs directly attributable to the process of placing the asset in conditions to be used. When some part of an item of the fixed assets has a different useful life to that fixed asset, it is recognized as a separate component (significant components of fixed assets). This item includes the amounts of property, land, furniture, vehicles, technological equipment, and other facilities own by the consolidated entities or acquired under financial leases. These assets are classified based on their use in:

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 37 Note 2 - Summary of Significant Accounting Policies, continued (i) Fixed assets for own use Fixed assets for own use includes, but is not limited to, tangible assets received by the consolidated entities in full or partial satisfaction of financial assets representing accounts receivable from third parties which are intended to be held for continuing own use and tangible assets acquired under finance leases. These assets are recorded at acquisition cost less the related accumulated depreciation and, if applicable, any impairment losses (when net carrying amount was higher than recoverable amount). For accounting purposes, acquisition cost of the received asset is considered to be its net amount. Depreciation is calculated using the straight line method over the acquisition cost of assets less their residual value, assuming that the land on which buildings and other structures stand has an indefinite life and, therefore, is not subject to depreciation. Fixed assets in leased properties are depreciated over the shorter period of time between their useful lives or the term of the lease, unless it is certain that the Bank will acquire the property at the end of the lease. The consolidated entities assess at each reporting date whether there is any indication that the carrying amount of any tangible asset exceeds its recoverable amount. If this is the case, the carrying amount of the asset is reduced to its recoverable amount and future depreciation charges are adjusted in accordance with the revised carrying amount and to the new remaining useful life. In a similar manner, when indication exists that a material asset has recovered its value, the consolidated entities recognize the impairment loss reversal and the future depreciation charges are adjusted accordingly. In no case the impairment loss reversal of an asset can increase its value over the initial value as it no impairment losses were recognized in previous years. Also, at least at the end of the year, the estimated useful lives of the items of property, plant and equipment for own use are reviewed in order to detect significant changes therein, which, if any, will be adjusted by means of the corresponding correction of the charge to the consolidated statement of income for future years, by recalculating the depreciation, by virtue of the new useful lives. Upkeep and maintenance expenses relating to tangible assets held for own use are recorded as an expense in the period in which they are incurred. (ii) Assets leased out under operating leases The criteria used to record the acquisition cost of assets leased out under operating leases, to calculate their depreciation and their respective estimated useful lives, and to record the impairment losses thereof, are consistent with those described in relation to fixed assets held for own use.

These are assets for which the cost can be reliably measured and it is probable that future economic benefits attributable to the asset will flow to the Bank. The cost of intangible assets acquired or originated in a business combination correspond to its fair value at the acquisition date. Intangible assets are recorded initially at acquisition or production cost and are subsequently measured at cost less any accumulated amortization and any accumulated impairment losses. The Bank shall assess whether the useful life of an intangible asset is finite or indefinite and, if finite, the length of, or number of production or similar units constituting, that useful life. An intangible asset shall be assessed by the Bank as having an indefinite useful life when, based on an analysis of all of the relevant factors, there is no foreseeable limit to the period over which the asset is expected to generate net cash inflows for the Bank. The accounting for an intangible asset is based on its useful life. An intangible asset with a finite useful life is amortized over its economic useful life and is reviewed to determine whether there was any indication that the intangible asset may have suffered any impairment, the period and method of amortization are reviewed at least at the end of each reporting period. An intangible asset with an indefinite useful life is not amortized. The Bank tests for impairment by comparing its recoverable amount with its carrying amount annually and whenever there is an indication that the intangible asset may be impaired. (i) Software The software acquired by the Bank is recognized at cost less the accumulated amortization and impairment, if any. The expenses in software developed internally are recorded as assets when the Bank is capable of proving its intention and ability to complete development, when internal use will generate future economic benefits and/or decrease in costs, and when the cost of completing its development can be reliably measured. The capitalized costs of the software developed internally include all the direct costs attributable to the development of the software, and it is amortized over the course of its useful life. Software developed internally is recorded at cost less the accumulated amortization and losses from impairment. The subsequent expenditures associated with the asset are capitalized only when future economic benefits from them will flow to the Bank. The rest of the expenditures are recognized in income. Intangible assets are amortized on a straight-line basis over their estimated useful life; starting on the date it is ready for use.

The fair value of an intangible asset represents expectations of market participants at the acquisition date over the probability that future economic benefits from the asset will flow to the entity. In other words, the entity expects that economic benefits flows to them, even though there is uncertainty about the date or the amount of them. As set forth by IAS 38 “Intangibles Assets” and IFRS 3, the acquirer will recognize an intangible assets from the acquiree at the acquisition date separately from Goodwill independently if the asset was previously recognized by the acquiree before the business combination. In connection with the aforementioned, the business combination between Itaú Chile and CorpBanca gave rise to intangible assets and Goodwill as indicated in Note 15 “Intangible Assets”. (iii) Other identifiable intangible assets Correspond to those intangible assets that can be identified, the Bank controls them, can be reliably measured and it is probable that future benefits will flow to the Bank. r) Factoring transactions The Bank performs operations with their clients, in which they receive invoices and other credit representative trading instruments with or without recourse to the transferor, anticipating a percentage of the total amount receivable of the borrower upon collection. These transactions are valued at the disbursed amounts by the Bank in exchange for invoices or other credit representative trading instruments. The price differences between the disbursed amounts and the nominal amount of the documents are recorded in the Interim Consolidated Statement of Income as interest income applying the effective interest rate method, over the term of the transaction. The responsibility of payment of the documents remains with the client (assignor). s) Leases On the date of commencement of a lease the Bank recognizes an asset for right of use and a liability for lease in accordance with the provisions of IFRS 16 “Leases”. (i) Assets for right-of-use At the beginning of a lease, the right-of-use asset is measured at cost. The cost includes (a) the amount of the initial measurement of the lease liability; (b) lease payments made before or from the start date, less lease incentives received; (c) the initial direct costs incurred by the lessee; and (d) a modification of the costs to be incurred by the lessee when dismantling and eliminating the underlying asset, restoring the place in which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 40 Note 2 - Summary of Significant Accounting Policies, continued After the initial recognition date, the Bank measures the assets by right of use applying the cost model, which is defined as the asset by right of use measured at cost (a) less accumulated depreciation and accumulated risk losses of value; and (b) adjusted for any new measurement of the lease liability. The Bank applies the depreciation requirements established by IAS 16 "Property, plant and equipment" over the right-of-use in these type of transactions. If the lease transfers ownership of the underlying asset to the Bank at the end of the lease term or if the cost of the right-of-use asset reflects that the Bank exercises a purchase option, the Bank depreciates the right-ofuse asset from the date of beginning of it until the end of the useful life of the underlying asset. In another case, the Bank depreciates the asset by right of use from the start date until the end of the useful life of the asset whose right of use has or until the end of the lease term, whichever comes first. The Bank applies IAS 36 “Impairment of assets” to determine if the right-of-use asset presents changes in value and accounts for identified value risk losses. As of September 30, 2023 and December 31, 2022, the Bank has not identified impairment in the value of the right-of-use assets. (ii) Lease liability The Bank measures the lease liability at the present value of lease payments that have not been paid as of that date. Lease payments are discounted using the interest rate implicit in the lease, if that rate could be easily determined. Since that rate cannot be easily determined, the Bank uses the incremental rate for loans (cost of funding). The lease payments included in the measurement of the lease liability determined the payments for the right of use the underlying asset during the term of the not cancelable lease at the measurement date which includes (a) fixed payments, less any lease incentive receivable (b) variable lease payments, which depends on an index or rate, recently measured using the index or rate on the start date; (c) it matters that the lessee expects to pay as residual value guarantees; (d) the exercise price of a purchase option if the lessee is reasonably sure to exercise that option; and (e) payments for penalties arising from the termination of the lease, if the term of the lease reflects that the lessee exercises an option to terminate the lease. After the date of initial recognition, the Bank measures the lease liability in order to recognize (a) the interest on the lease liability; (b) lease payments made; and (c) the new measurements or modifications of the lease, and also for fixed lease payments that have essentially been reviewed. The Bank makes new measures of the lease liability discounting the modified lease payments, if (a) there is a change in the expected amounts payable related to a residual value guarantee. A lessee will determine the lease payments to determine the change in the amounts expected to be paid under the residual value guarantee; (b) there will be a change in future lease payments determined from a change in an index or a rate used to determine those payments.

The Bank will determine the revised lease payments, for the remainder of the lease term, based on the revised contractual payments. The Bank measured the lease liability at the present value of the lease payments discounted using the incremental interest rate for loans (cost of funding). t) Provisions for credit risk on "Interbank Loans" and "Loans and accounts receivable from customers" The Bank has established provisions for impairment losses due to credit risk on "Interbank Loans", "Loans and receivables from customers" and "Contingent loans", in accordance with the instructions defined in the compendium, issued by the Commission for the Financial Market (CMF), and the credit risk rating and evaluation models approved by the Bank's Corporate Governance, in order to make the necessary and sufficient provisions in a timely manner to cover the expected losses associated with the characteristics of the debtors and their receivables, which determine the payment behavior and subsequent recovery. The processes and compliance with the policy are evaluated and supervised in accordance with internal control procedures, in order to ensure compliance and the maintenance of an adequate level of provisions to support expected losses. Provisions determined and denominated "individual allowances", correspond to debtors that are individually, assesed due to size, complexity or level of exposure to the Bank, it is necessary to know and analyze in detail. Provisions determined and denominated "group allowances", includes individuals or smaller companies, and are associated to a high number of transactions with homogeneous characteristics and that due to such conditions are evaluated collectivelly. In order to establish allowances for loan losses, an assessment of the loans and contingent loans portfolios is performed as indicated below: x Individual allowances for the normal portfolio. x Individual allowances for the substandard portfolio. x Individual allowances for the impaired portfolio. x Group allowances for the normal portfolio. x Group allowances for the impaired portfolio. (i) Individual allowances When a debtor is considered as individually significant, i.e. with significant levels of debt and for those ones that are not significant but cannot be classified in groups of financial assets with homogeneous credit risk characteristics, and due to its size and complexity or exposure it is required to be individually assessed. The methodology used to classify and determine its allowances is performed in accordance with Chapter B-1 “Provisions for credit risk” from the compendium, assigning risk categories to each debtor according to the following portfolio:

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 42 Note 2 - Summary of Significant Accounting Policies, continued Normal portfolio Corresponds to debtors whose capacity payments allows them to comply with their obligations and commitments, and according to the economic-financial situation this condition will not change. The classifications assigned to this portfolio are the categories that goes from A1 to A6. Notwithstanding the above, the Bank must maintain a minimal allowance percentage of 0.5% over its loan portfolio and contingent loans that form part of the Normal portfolio. Substandard portfolio Includes the borrowers which have financial difficulties, or whose payment capacity worsened significantly, presenting reasonable doubt regarding the probability principal and interest under the contractually agreed terms, indicating that they are less likely to comply with their financial obligations in the short term. In addition, borrowers that recently held loans in default for over 30 days also are included in the substandard portfolio. The classifications assigned to this portfolio are categories B1 to B4. Normal and Substandard portfolios As part of the debtors’ individual analysis, the Bank classifies its debtors into the aforementioned categories, assigning probabilities of default (PD) and loss given default (LGD), which yield the expected loss percentages as a result. These variables are regulated by the CMF- to be applied to each of the individual categories. Below are presented the probabilities of default and loss given default, as established by the CMF: Probability of Loss given Expected Category of default default loss Type of portfolio debtor (DP) (PLD) (EL) (%) (%) (% Provisión) A1 0.04 90.00 0.03600 A2 0.10 82.50 0.08250 Normal portfolio A3 0.25 87.50 0.21850 A4 2.00 87.50 1.75000 A5 4.75 90.00 4.27500 A6 10.00 90.00 9.00000 B1 15.00 92.50 13.87500 B2 22.00 92.50 20.35000 Substandard portfolio B3 33.00 97.50 32.17500 B4 45.00 97.50 43.87500 In order to determine the amount of provisions, the Bank first determines the affected exposure, which comprises the book value of the customer's placements plus the contingent credits, less the amounts that are feasible to recover through the execution of the guarantees, financial or real, backing the operations, to which the respective loss percentages are applied. In the case of collateral, the Bank must demonstrate that the value assigned to this deduction reasonably reflects the value it would obtain on the disposal of the assets or equity instruments. In the case of substitution of the debtor's credit risk for the credit quality of the guarantor or surety, this methodology will only be applicable when the guarantor or surety is an entity rated in a category similar to investment grade by a local or international rating agency recognized by the regulator. Guaranteed values may not be deducted from the exposure amount. The procedure apply only in the case of financial or real guarantees.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 43 Note 2 - Summary of Significant Accounting Policies, continued Impaired portfolio Includes the loans to borrowers for which recovery is considered remote, given that they have suffered a loss event resulting in impairment. This portfolio includes borrowers with evident signs of possible bankruptcy, as well as those in which a forced debt renegotiation is required, and also includes any borrower with loans in default for equal to or greater than 90 days in the payment of interest or principal of any loan. The classifications assigned to this portfolio are categories C1 to C6. Applied to all credits, including 100% of the amount of contingent credits, held by those same debtors. For purposes of establishing provisions on this portfolio, in the first instance an expected loss rate is determined, deducting from the amount of the exposure the amounts susceptible to recovery through the execution of financial and real guarantees that support the operations and also deducting the present value of the recoveries obtained through collection actions net of associated expenses. Once the expected loss range has been determined, the respective allowance percentage is applied to the amount of the exposure comprising the placements plus the contingent credits of the same debtor. Allowance percentages to be applied over the exposition are as follows: Type of portfolio Risk scale Expected loss range Provision C1 Up to 3% 2% C2 More than 3% and up to 20% 10% C3 More than 20% and up to 30% 25% Impaired portafolio C4 More than 30% and up to 50% 40% C5 More than 50% and up to 80% 65% C6 More than 80% 90% Loans are maintained in this portfolio until a normalization of their payment capacity or behavior is observed, without prejudice to the write-off of each particular loan that meets the condition set forth in Title II of Chapter B-2 of the compendium. In order to remove a debtor from this portfolio, once the circumstances that led to its classification in this portfolio under these rules have been overcome, at least the following copulative conditions must be met: x None of the debtor obligations with the Bank are overdue for more than 30 days. x No new re-financing of loans has been granted. x At least one of the payments received includes principal payment (total or partial). x If the debtor has a loan with partial payments due within six months, two payments have been made. x If the debtor has to pay monthly installments for one or more loans, at least four consecutive installments have been paid. x The debtor shows no direct unpaid debts in the consolidated information provided by the CMF, unless those debts are not material.

This type of assessment, as well as the criteria to apply for them, must be consistent with those used when loans were granted. To establish allowances, collective assessment requires grouping loans with homogeneous characteristics in terms of type of debtor and loan conditions, in order to conform, by technically formulated methodologies and following prudential criteria, the payment behavior of the group and the recoveries for defaulted loans. Based on the above, the groups are assigned with a probability of default (PD) and loss given default (LGD) considering the profile that best suits the loan. Net exposure is calculated, which includes the book value of the loan plus contingent loans. Standard method for mortgage loans allowances For the purposes of calculating credit risk provisions of the mortgage loan portfolio for mortgage , the Bank uses the standard provision method for mortgage loans established in the compendium. According to this method the provision factor to be applied, represented by the expected loss (EL) over the amount of the mortgage loans, depends on the overdue of each loan and the relation, at the end of each month, between the gross exposure and the corresponding collateral (LTV), according to the following table: Days past due at Portfolio in PVG tranche month-end 0 1 - 29 30 - 59 60 - 89 default PI (%) 1.0916 21.3407 46.0536 75.1614 100 PVG ” 40% PDI (%) 0.0225 0.0441 0.0482 0.0482 0.0537 PE (%) 0.0002 0.0094 0.0222 0.0362 0.0537 PI (%) 1.9158 27.4332 52.0824 78.9511 100 40% < PVG ” 80% PDI (%) 2.1955 2.8233 2.9192 2.9192 3.0413 PE (%) 0.0421 0.7745 1.5204 2.3047 3.0413 PI (%) 2.5150 27.9300 52.5800 79.6952 100 80% < PVG ” 90% PDI (%) 21.5527 21.6600 21.9200 22.1331 22.2310 PE (%) 0.5421 6.0496 11.5255 17.6390 22.2310 PI (%) 2.7400 28.4300 53.0800 80.3677 100 PVG > 90% PDI (%) 27.2000 29.0300 29.5900 30.1558 30.2436 PE (%) 0.7453 8.2532 15.7064 24.2355 30.2436

For mortgage loans related to housing programs and benefits from the Government, when guaranteed by the corresponding auction insurance, the allowance percentage could be weighted for a loss mitigating factor, which depends on the LTV percentage and the value of the property at inception. The loss mitigating factors are those shown in the table below: MP loss mitigation factor for credits with PVG tranche state auction insurance V tranche: Price of the house upon executing sale agreement (UF) V ” 1,000 1,000 < V ” 2000 PVG ” 40% 100% 100% 40% < PVG ” 80% 100% 100% 80% < PVG ” 90% 95% 96% PVG > 90% 84% 89% Provisions for Commercial Loans The Bank uses the three standard models established in the compendium, in order to determine the provisions of the group commercial portfolio. The applicable percentages of provision and the parameters used to determine the provision, are set out on the compendium. x Commercial leasing operations The allowance is determined based on the book value of the commercial lease operations (including the purchase option). The allowance percentage used in the calculation will depend on the delinquency of each operation, the type of leased asset and the relationship, at the end of each month, between the book value of each operation and the value of the leased asset (LTV), as indicated in the following tables: Probability of Default (PD) applicable according to delinquency and type of asset (%) Days of delinquency of transaction Type of asset at end of month Real Estate Non-real estate 0 0.79 1.61 1 - 29 7.94 12.02 30 - 59 28.76 40.88 60 - 89 58.76 69.38 Portfolio in default 100.00 100.00

The factor used is determined based on whether the operation has guarantees and it’s overdue. In addition for those operations with guarantees, the relationship between the debtor´s obligations to the bank and the value of the guarantees (LTV) is used to determine the factor as indicated in the following tables: Probability of Default (PD) applicable according to delinquency and PTVG tranche (%) Days past due at month-end With guarantee Without guarantee PTVG <=100 % PTVG >100 % 0 1.86 2.68 4.91 1-29 11.60 13.45 22.93 30-59 25.33 26.92 45.30 60-89 41.31 41.31 61.63 Portfolio in default 100.00 100.00 100.00 Loss Given Default (LGD) applicable according to PTVG tranche (%) Commercial generic transactions Factoring with or factoring without liability of the PTVG tranche liability of the assigner assigner PTVG <= 60% 5.00 3.20 With guarantee 60% <PTVG <= 75% 20.30 12.80 75% <PTVG <= 90% 32.20 20.30 90% < PTVG 43.00 27.10 Without guarantee 56.90 35.90 A guarantee or collateral can only be considered if, the guarantee was constituted in favor of the Bank with preference and if the guarantees is directly associates with the debtor´s credits (not shared with other debtors). For the purposes of calculating the LTV, the invoices assigned in the factoring operations, nor the guarantees associated with mortgage loans can be considered. The guarantees used in calculating the LTV relationship may be of a specific or general purpose, including those that are simultaneously specific and general. In the case of specific guarantees, the PTVG ratio must be calculated independently for each secured transaction, as the division between the amount of the placement and the contingent credit exposure and the value of the collateral securing it. For general and specific guarantees, LTV is determined as the division between the sum of the amounts of the loan and exposures of contingent credits and the general and specific guarantees considering any restriction.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 48 Note 2 - Summary of Significant Accounting Policies, continued x Provisions associated with financing guaranteed by FOGAPE Covid 19 On July 17, 2020, the CMF requested the determination of specific provisions for loans guaranteed by the FOGAPE Covid-19 guarantee, for which the expected losses should be determined by estimating the risk of each transaction, without considering the substitution of the credit quality of the guarantee, according to the individual or group analysis method, in accordance with the provisions of Chapter B-1 of the Compendium of Accounting Standards. This calculation must be made on an aggregate basis, grouping all those operations to which the same deductible percentage is applicable. Therefore, the total amount of expected losses resulting from the aggregate calculation of each group of operations must be contrasted with the respective total amount of deductible applicable to them and proceed as follows, when the expected losses of the operations of a group to which the same deductible percentage is applicable, determined according to the above procedure are less than or equal to the aggregate amount of the deductible, the provisions will be determined without considering the coverage of FOGAPE Covid-19, that is, without substituting the credit quality of the direct debtor for that of the guarantor, and when they are greater than the aggregate amount of the deductible, the provisions will be determined using the substitution method provided for in numeral 4. 1 letter a) of Chapter B-1 of the Compendium and will be recognized in accounts separate from commercial, consumer and mortgage provisions. As of September 30, 2023 and December 31, 2022 the Bank has recorded provisions of MCh$5,049 and MCh$8,721, respectively. x Provisions for contingent loans The Bank maintains in off-balance accounts amounts related to commitments or responsibilities due to its normal activities: Guarantees, letters of credit, documented guarantees, available lines of credit, other loans commitments, and other contingent loans. The amount of contingent loans is considered at the end of each reporting period in order to calculate provisions for loans losses according to Chapter B-1 of the Compendium, using the methodology set forth in letter b) “Guarantees”. Impaired portfolio – Collectively assessed loan The group in default loan portfolio comprises all loans and 100% of the amount of contingent loans of debtors who at the end of a month are 90 days or more past due in the payment of interest or principal on any loan. It will also include debtors who have been granted a loan to leave in force a transaction that was more than 60 days overdue, as well as debtors who have been subject to forced restructuring or partial forgiveness of a debt. The following can be excluded from the group impaired portfolio: a) Mortgage loans overdue for less than 90 days, unless the debtor has another loan of the same type with large overdue; and, loans for financing higher education under Law 20,027, b) that do not yet meet the default conditions set forth in Circular 3,454 of December 10, 2008.

In order to remove a debtor from the Impaired portfolio, once the circumstances that made it be classified in this category are overcome according to these standards, all the following requirements must be met: 1) None of the debtor obligations with the Bank are overdue for more than 30 days. 2) No new re-financing of loans has been granted. 3) At least one of the payments received includes principal payment (total or partial). 4) If the debtor has a loan with partial payments due within six months, two payments have been made. 5) If the debtor has to pay monthly installments for one or more loans, at least four consecutive installments have been paid. 6) The debtor shows no direct unpaid debts in the consolidated information provided by the CMF, unless those debts are not material. (iii) Guarantees Las Guarantees can be considered for allowances calculation purposes only if they are legally documented and comply with all conditions and requirements to be executable in Bank’s favor. In all cases, for purposes of the standards established by the CMF, the Bank should be able to demonstrate the mitigating effect of the guarantees over the inherent credit risk of the exposures. For allowances calculation purposes, guarantees will be treated according to the following, as applicable: 1) Collateral and guarantees. Considers contractual agreements to guarantee a specific loan or loans in a way that the coverage over the exposure can be clearly defined and where the rights to collect have been unquestionably transferred over to the guarantor. 2) Guarantees. In order to apply the deduction method or to determine recovery rates, valuation of property and other guarantees (mortgages or financial instruments guarantees) must reflect the net inflow that will be obtained from the sale of the assets, debts instruments or shares in the event that the borrower falls into default and a secondary source of payment is required. In applying the deduction method, the amount to be recovered by executing the guarantee, corresponds to the present value of the asset sold in its current market condition at disposal, minus all expenses required to keep the asset in its current conditions and to sell them, all in accordance with the Bank policies and terms established by Law for assets disposal. 3) Security deposit. On this type of guarantees the adjustment of its fair value may be deducted from the exposition, solely when the guarantee can be established with the unique aim to guarantee compliance with the related loans.

Estimated losses when establishing allowances based on the assessment method corresponding to each debtor, consider the amount that will be obtained if the leased asset are sold, taking into account any potential impairment for the assets in case of debtor’s default and the related recovery and relocation expenses. 5) Factoring operations. Establishing allowances for factoring operations will consider as counterparty the entity ceding rights over the endorsed in favor of the Bank, when the cession is recourse for the latter, and to the debtor when the cession has been made without recourse. (iv) Additional provisions The Bank can establish provisions in addition to those calculated by applying the loan portfolio assessment models, according to the set forth in number 9 of Chapter B-1 of the compendium. These provisions can be established with the purpose of addressing the risks arising from macroeconomic fluctuations by anticipating expansive economic cycle downturns which could materialize in the worsening of the economic environment in the future and, in that manner, operate as an anti-cycle mechanism to accumulate additional provisions during positive economic conditions and release or use provisions when negative economic conditions are present. According to the above, additional provisions shall always correspond to general allowances for commercial, consumer or mortgage loans, or to identify segments of them and in no case can be used to compensate deficiencies in the Bank’s models. As of September 30, 2023, the Bank maintained additional provisions for its commercial, consumer and mortgage loan portfolio amounting to MCh$176,407 (as of December 31, 2022, the Bank maintained additional provisions of MCh$175,501). u) Impaired credits and charge-offs Impaired loans This portfolio is comprised of the following assets: x For individually assessed debtors, includes loans classified in the “Impaired portfolio” and those classified under categories B3 and B4 of the “Substandard portfolio”, as described above. x For those debtors collectively assessed, includes all loans classified in the “Impaired portfolio”. Charge-offs As a general rule, charge-offs should be applied when contractual rights to cash flows expire. In the case of placements, even if this does not occur, the respective asset balances will be written off in accordance with the provisions of the compendium, Chapter B-2, Title II "Impaired and written-off loans". The write-offs in question refer to the derecognition in the Interim Consolidated Statement of Financial Position of the asset corresponding to the respective operation, including, therefore, that part which might not be due if it were a loan payable in instalments or partial payments, or a leasing operation.

Charge-off of loans and accounts receivable must take place when the following circumstances exist, whichever happens first: 1) The Bank, based on all available information, concludes that no inflow related to the recorded loan will be received. 2) When a loan or account receivable with no legal documentation is 90 days overdue since recorded as an asset. 3) When the legal term for all legal shares to collect the loan have expired. When a loan is overdue for a period of time that complies with the term listed below: Type of loan Term Consumer loans with or without collateral 6 months Consumer leasing 6 months Other operations of non real estate leasing 12 months Other transactions without collateral 24 months Commercial loans with collateral 36 months Real estate leasing (commercial and home purchase) 36 months Mortgage loans for home 48 months The term corresponds to the time passed since the date in which the loan became collectable partially or totally. Recovery of assets previously charged-off Payments received from loans previously charged-off are recognized directly as income, as recoveries of loans previously charged-off in “Expense for credit losses” compensating the provision expense for the period. In the event that recoveries through goods or non-financial assets income will be recognized for the amount in which those assets are recorded, according to Chapter B-5 “Assets received in lieu of payment” of the compendium. Same criteria will be followed for repossessed leased assets granted under finance leases, after being charged-off when incorporated back as assets. Renegotiation of previously charged-off loans Any renegotiation of a written-off loan will not give rise to income as long as the transaction continues to be impaired, and the actual payments received must be treated as recoveries of written-off loans. The renegotiated loan is recorded as an actual asset when losses its characteristic of impaired, recording income as a recovery of a loan previously charged-off. Same criteria is applied when a loan is granted to pay for a loan previously charged-off.

The amount of contingent loans is considered at the end of each reporting period in order to calculate provisions for loans losses according to Chapter B-1 of the Compendium of Accounting Standards, using the methodology set forth in letter b) “Guarantees”. x) Income taxes and deferred taxes The Bank has recognized an expense (income) arising from gains or losses for each period, according to the applicable taxation rules for each country or jurisdiction it operates. The income tax expense for the period includes the sum of current tax, which results from applying the current rates to the taxable profit for the period (after deducting the tax credits allowed), and the change in deferred tax assets and liabilities recognized in the Interim Consolidated Statement of Income. The Bank records, when appropriate, deferred tax assets and liabilities for the estimated future tax effects attributable to differences between the carrying amount of assets and liabilities and their tax basis. The measurement of deferred tax assets and liabilities is based on the tax rate, in accordance with the applicable tax laws, using the tax rate that applies to the period when the deferred asset and liability will be settled. The effects of deferred taxes on temporary differences between the balance sheet and the income statement are recognized in deferred taxes as of the date on which the law approves such changes.

Provisions are recorded in the Interim Consolidated Statement of Financial Position when the Bank: x Has a present obligation (legal or constructive) as a result of past events, x It is probable that an outflow of resources will be required to settle these obligations, and x The amount of these resources can be reliably measured. A contingent liability is any possible obligation arising from past events whose existence will be confirmed by the occurrence or non-occurrence of one or more uncertain future events that are not wholly within the control of the Bank. Guarantees agreement, confirmed foreign letters of credit, letters of credit, letters of guarantee, unused lines of credit, other credit commitments, other contingent credits (see letter v) are classified as contingent in supplementary information. Provisions (quantified using the best available information on the consequences of the event giving rise to them and are reviewed and adjusted at the end of each year) are used to satisfy specific obligations for which they were originally recognized. Partial or total reversals are recognized when such liabilities cease to exist or are reduced. Provisions are classified according to the obligations covered, being for the purpose of these Interim Consolidated Financial Statements, those detailed in note 24 "Provisions for contingencies", note 25 "Provisions for dividends, interest payments and repricing of regulatory capital financial instruments issued" and note 26 "Special provisions for credit risk". z) Employee benefits Employee benefitsShort-term benefits Correspond to personnel benefits (other than termination benefits) that are expected to be settled within twelve months after year end over which the employees have rendered their services. These are recognized when the employee has rendered the service and are measured at the undiscounted amount of benefits expected to be paid in exchange for that service: x As a liability (accrued expense), after deducting any obligation already satisfied. If the amount already paid is higher than the gross amount of the benefits, the Bank will recognize this excess as an asset (amount paid in advance), when it represents a reduction of future payments or a recoverable amount in cash. x As an expense when the entity consumes the economic benefit arising from the service provided by an employee in exchange for employee benefits, unless other IFRS requires or allows the recognition of those disbursements as part of the cost of an asset.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 55 Note 2 - Summary of Significant Accounting Policies, continued Personnel vacations The annual cost of personnel vacations and benefits are recognized on an accrual basis. Post-employment benefits Correspond to employee benefits (other than termination benefits and short-term employee benefits) that are expected to be settled after the completion of employment. Post-employment benefits plans are agreements, formal and informal, in which the Bank is committed to provide benefits to one or more employees after completion of their employment. Plans providing these benefits are classified as either defined contribution plans or defined benefit plans, depending on the economic substance of the plan as derived from its principal terms and conditions. Defined contribution plans, the obligation is recognized for the amounts to be contributed in the period. Defined benefit plans, a liability is recognized based on the estimated benefit cost that employees have accrued for services rendered, less the present value of the defined benefit obligation and present value of present services. Present service cost and gain or loss upon settlement will be recognized in the income statement for the period. Gains and losses generated from the remeasurement of the liability will be recognized in other comprehensive income. Other long-term benefits Other long-term employee benefits are employee benefits, other than short-term, post-employment and termination benefits, which are not due for payment within 12 months after the end of the period in which the employees render the service. The regulations require the recognition of a liability for the present value of the defined benefit obligation less the fair value of the plan assets, if any. The results generated from its remediation will be recognized in the results of the period. Termination benefits Termination benefits are employee benefits provided in exchange for the termination of an employee’s employment, as a consequence of: x A decision of the entity to terminate the employee’s employment before the normal termination date; or x The decision of an employee to accept an offer with benefits in order to terminate the employment before the normal termination date. An entity recognizes a liability and expense for termination benefits at the earlier of the following dates: x When the entity can no longer withdraw the offer of those benefits; and x When the entity recognizes costs for a restructuring that is within the scope of IAS 37 “Provisions, contingent liabilities and contingent assets” and involves the payment of termination benefits.

The Bank recognizes a liability for cash-settled share-based payment transactions at fair value at the inception of each contract. Until the liability is settled, the Bank will remeasure the fair value of the liability at the end of each reporting period and at the settlement date, and will recognize any fair value variation in profit or loss for the period. aa) Provision for mandatory dividends A liability recognized due to the legal obligation to distribute 30% of the profit of the year in compliance with Public Company Law (30%) or in accordance with the provisions of the company bylaws. For the three and nine months periods ended September 30, 2023 and the yeard ended as of December 31, 2022, the Bank provisioned 30% of its net income. This provision is recorded as a decrease in "Retained earnings" under "Provision for dividends, interest payments and repricing of issued regulatory capital financial instruments" in the Interim Consolidated Statement of Changes in Shareholders' Equity. In the Bank’s bylaws, title VII, it is established that the Bank should distribute annually as a dividend to its shareholders, as a proposal of the Board of Directors and based on the number of shares, at least thirty percent (30%) of the net income of the year. Furthermore, no dividends distribution will take place if there are equity losses (negative reserves) until these losses are recovered or if a dividend distribution will cause a non-compliance of the capital requirements established by the General Bank Law. bb) Assets received or awarded in lieu of payment Assets received or awarded in lieu of payment of loans and accounts receivable from clients are recognized at their fair value (as determined by an independent appraisal). A price is agreed upon by the parties through negotiation or, when the parties do not reach an agreement, at the amount at which the Bank is awarded those assets at a judicial auction. In both cases, an independent appraisal is performed. These assets are subsequently adjusted to their net realizable value less cost to sale, and the difference between the carrying value of the asset and the estimated fair value less costs to sell is charged to income, under “Other operating expenses”. Assets received or foreclosed in payment are valued at the lower of initial value and net realizable value, i.e. fair value (independent appraisal) less costs to hold and dispose of, plus regulatory write-offs. Regulatory write-offs are required by the regulator if the asset is not sold within one year of receipt. Such net realizable value of an assets is determined mainly in conformity with the current market conditions, and should correspond to its fair value less the necessary costs to maintain and dispose it.

However, the regulator, by means of general rules, may establish that, in justified cases, the Bank may have an additional term of up to eighteen months for the disposal of the assets. In order to be eligible for the extension, the value of the asset must have been written off for accounting purposes, in compliance with Article 84 of the General Banking Law. cc) Customer loyalty programs The Bank maintains a loyalty program to provide incentives to its customers, allowing them to purchase goods or services with certain benefits which are granted through credit cards issued by the Bank when they purchase according to the conditions established for each loyalty program. The Bank has an adequate level of provisions in order comply with its current obligations and to properly reflect the associated expense when providing the benefits. dd) Non-current assets held for sale Non-current assets (or a group holding assets and liabilities for disposal) expected to be recovered mainly through the sale of these items rather than through the continued use, are classified as held for sale. Immediately prior to this classification, assets (or elements of a disposable group) are re-measured in accordance with the Bank’s policies. The assets (or disposal group) are measured at the lower of carrying amount and fair value less cost to sell. Impairment losses in initial classification of non-current assets held for sale and with subsequent gains and losses are recorded in income. Gains are not recorded over previously recorded losses. ee) Earnings per share Basic earnings per share are determined by dividing the net income attributable to the equity holders of the Bank for the reported period by the weighted average number of shares outstanding during the reported period. Diluted earnings per share are determined in the same way as basic earnings, but the weighted average number of outstanding shares is adjusted to take into consideration the potential diluting effect of stock options, warrants, and convertible debt. As of September 30, 2023 and December 31, 2022 the Bank did not have any instruments that generated dilution.

The classification of cash flows into the aforementioned categories provides information that allows users to evaluate the impact of the transactions in the financial position of the Bank, as well as over the ending balance of cash and cash equivalents. This information can be also useful when evaluating the relation between those activities (IAS7) . For the preparation of the Interim Statement of Cash Flows, the Bank used the indirect method, in which from the consolidated income for the period before income tax, non-cash transactions are subsequently added/subtracted, as well as income and expenses associated with cash flows classified as investing or financing activities. For the preparation of the Interim Statement of Cash Flow, the following items are considered: x Cash flows: Inflows and outflows of cash and cash equivalents, such as deposits with the Central Bank of Chile, deposits in domestic banks, and deposits in foreign banks. x Operating activities: Principal revenue-producing activities performed by banks and other activities that cannot be classified as investing or financing activities. This section includes, among others, loans obtained from abroad, dividends received from investments, financial instruments at fair value through other comprehensive income and amortized cost, etc. x Investing activities: Correspond to the acquisition and disposal of long-term assets and other investments not included in cash and cash equivalents. x Financing activities: Activities that result in changes in the size and composition of the equity and liabilities that are not part of operating activities nor investing activities. For the purposes of the Interim Statement of Cash Flows, cash and cash equivalents have been considered as cash and cash equivalents, the balances of "Cash and bank deposits" plus the net balance of operations in liquidation in progress, plus financial instruments for trading at fair value through profit or loss and financial instruments at fair value through other comprehensive income with high liquidity and with insignificant risk of change in value, whose maturity does not exceed three months from the date of acquisition and the rights under resale agreements and securities lending that are in that situation. Includes also investments in fixed income mutual funds which are presented under trading investments in the Consolidated Statement of Financial Position. Cash and cash equivalents balances and their reconciliation to the Interim Consolidated Statement of Cash Flows are detailed in Note 7 “Cash and Cash Equivalents”. The provision for loan losses included under the operating activities section differs from the amount presented in the Interim Consolidated Statement of Income, because for cash flows purposes such amount excludes recoveries of transactions previously charged-off.

This statement shows a conciliation between opening and ending balances for the period for all items that form part of consolidated equity, grouping transactions based on their nature, according to the following: x Adjustments for changes in accounting criteria and correction of errors: which include changes in consolidated net equity arising as a result of the retrospective restatement of balances in the Interim Consolidated Financial Statements due to changes in accounting criteria or correction of errors. x Net comprehensive income for the period: Includes in an aggregated manner net income for the period recorged in the Interim Statement of Other Comprehensive Income for the period, as previously indicated. x Other changes in equity: Includes retained earnings distributions, equity increases, provision for mandatory dividends, dividends paid, among other increases or decreases in consolidated equity. This information is presented in two statements: The Interim Consolidated Statement of Other Comprehensive Income and the Interim Consolidated Statement of Changes in Equity. hh) Consolidated Statement of Other Comprehensive Income In the Consolidated Statement of Other Comprehensive Income are presented income and expenses generated by the Bank as a consequence of its regular activities during the year, clearly identifying those recorded in profit and loss from those recorded in net equity. Due to this, in this statement the following is shown: x The consolidated income for the period. x Net amount of income and expenses recorded in equity as “Valuation accounts”. x Deferred income taxes originated by transactions described above, except for those amounts related to exchange differences from foreign net investments. Total amount of consolidated income and expenses recorded, calculated as the sum of the items listed above, presenting in those attributable equity holders of the Bank from non-controlling interest.

Standards and interpretations issued in the current period Circular No. 2,317 - Updates instructions of Chapter 18-5 of the RAN, regarding information on debtors of financial institutions. On July 29, 2022, in line with the process of improving the current register of debtors under the regulatory adjustment of Chapter 18-5 of the RAN, the CMF established a concrete framework that ensures the correct treatment and use of the data from the debtors list, under higher protection standards. This is achieved by requiring an Internal Policy on the Security and Management of Debtor Information (“PISMID” by its acronym in Spanish), so that the internal governance of the institutions receiving the list is particularly rigorous in terms of controls on the confidentiality of the information, ensuring compliance with the restrictions on use and access, and compatibility with international best practices. In connection with the above, the following amendments are made to Chapter 18-5 of the RAN for Banks:  Create Internal Policy on the Security and Management of Debtor Information (“PISMID” by its acronym in Spanish).  Appointment of an individual in charge of granting access to the different information views.  The register with access permits must be updated at least annually.  The right of access must be included; the right of rectification or modification in case the owner proves that the personal data is erroneous, inaccurate or outdated; and the right of cancellation, if applicable (it may be demanded in person or by digital means).  There must be systems that allow for the full registration and follow-up of claims; the preservation of files shall be governed by the provisions of RAN 1-10².  The policy must have the protection mechanisms contemplated in RAN 20-10³.  It must be approved by the Board of Directors (it must be updated, approved and audited, both internally and externally, at least once per calendar year). This circular will be effective as of July 1, 2023. Management is in the process of implementing the standard and believes this standard will have no impact on the presentation of the Interim Consolidated Financial Statements. Circular No. 2,318 - Incorporates new files R13 and R14 to the Risk System of the Banks Information System Manual involving the measurement and supervision of risks related to the Banking Book Market Risk (“RMLB” for its acronym in Spanish) and the Credit Concentration Risk (“RCC” for its acronym in Spanish). On August 12, 2022, the CMF, in order to obtain the information required for the application of Chapter 21-13 of the RAN for Banks, created files R13 "Banking Book Market Risk" and R14 "Credit Concentration Risk". As a result of the aforementioned amendments, effective July 13, 2023, the file C40 "Cash flows associated with interest rate and indexation risks in the banking book" of the Banks Information System Manual will no longer be reported. The latest information will be the one submitted as of September 30 of that year. It will be effective as of July 13, 2023.The Bank's Management will evaluate the impact that this standard will have on the presentation of Interim Consolidated Financial Statements.

On February 12, 2021, the IASB published amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors. The amendments clarify how companies should distinguish changes in accounting policies from changes in accounting estimates. That distinction is important because changes in accounting estimates apply prospectively only to future transactions and other future events, but changes in accounting policies generally also apply retrospectively to past transactions and other past events. The amendments to IAS 8 will be effective for annual reporting periods beginning on or after January 1, 2023, with early application permitted. The Bank's Management considers that the adoption of this amendment will have no significant impacts on the Interim Consolidated Financial Statements.

Sale or Contribution of Assets between an Investor and its Associate or Joint Venture (amendments to IFRS 10 and IAS 28) The amendments to IFRS 10 Consolidated Financial Statements and IAS 28 Investments in Companies and Joint Ventures (2011) address a recognized inconsistency between the requirements of IFRS 10 and those of IAS 28 (2011) in the treatment of the sale or contribution of assets between an investor and its associate or joint venture. The amendments, issued in September 2014, state that when the transaction involves a business (whether it is in a subsidiary or not) the entire generated gain or loss is recognized. A partial gain or loss is recognized when the transaction involves assets that do not constitute a business, even when the assets are in a subsidiary. The effective date for these amendments is yet to be determined because the IASB is awaiting the results of its research project on the equity method accounting. These amendments must be applied retrospectively and early adoption is permitted, which must be disclosed. The Bank's management will await the new effective date to evaluate the potential effects of these amendments. Amendments to IFRS 16 - Lease liability on a sale and leaseback On September 22, 2022, the IASB issued this amendment which clarifies how a selling lessee subsequently measures sale and leaseback transactions that meet the requirements of IFRS 15 to be accounted for as a sale. The new requirements do not prevent a seller-lessee from recognizing in profit or loss any gain or loss related to the partial or total termination of a lease. The effective date for the amendments is January 01, 2024. The Bank’s management is assessing the potential impact of the adoption of this amendment on its Interim Consolidated Financial Statements.

The amendments are effective for annual reporting periods beginning on or after January 1, 2024, with early adoption permitted.

(2) For tax purposes, the investment in Colombia and the United States is valued in U.S. dollars. The devaluation (appreciation) of the Chilean peso against the U.S. dollar generates income (expense) for tax purposes without a corresponding effect on profit or loss. The amount presented here represents the income tax expense (benefit) for the effect of the exchange rate on the investment in Colombia and the United States. As part of its exchange rate risk management policy, the Bank has managed this exposure through instruments available in the market to protect it economically from the tax effect generated by the fluctuation in the exchange rate. The effect of these instruments (which offsets the tax effect presented here) is recognized in the Net foreign exchange gain (loss) line of the Consolidated Statement of Income for the period. (3) Capital gains generated on sales of fixed-income instruments qualifying for the tax exemption under Article 104 of the Income Tax Law are not subject to income tax. (4) This line reflects the tax rate differences of companies located in other jurisdictions (ITAU Colombia and New York Branch), which are part of the Bank’s consolidated income. In the case of Colombia, Panama is included as a subsidiary.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 197 Note 44 – Fair Value of Financial Assets and Liabilities This disclosure was prepared based on the application of the local regulatory guidelines stated in Chapter 7-12 “Fair value of financial instruments” of the CMF and IFRS 13 “Fair value measurement”. These standards have been applied to both financial assets and non-financial assets measured at fair value (recurecurring and non-recurring). The following section details the main guidelines and definitions used by the Group: Fair value. The price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. an exit price). The transaction is carried out in the principal or most advantageous market and is not forced, that is, it does not consider factors specific to the Group that may influence a real transaction. Market participants. Buyers and sellers in the principal (or most advantageous) market for the asset or liability that have all of the following characteristics: a) They are independent of each other, i.e. they are not related parties as defined in IAS 24 “Related Party Disclosures”, although the price in a related party transaction may be used as an input to a fair value measurement if the entity has evidence that the transaction was entered into at market terms. b) They are knowledgeable, having a reasonable understanding about the asset or liability and the transaction using all available information, including information that might be obtained through due diligence efforts that are usual and customary. c) They are able to enter into a transaction for the asset or liability. d) They are willing to enter into a transaction for the asset or liability i.e. they are motivated, but not forced or otherwise compelled, to do so. Fair value measurement. When measuring fair value, the Group takes into account the same characteristics of the asset or liability that market participants would consider in pricing that asset or liability on the measurement date. Aspects of the transaction. A fair value measurement assumes that the asset or liability is exchanged in an orderly transaction between market participants to sell the asset or transfer the liability at the measurement date under current market conditions. The measurement assumes that the transaction to sell the asset or transfer the liability takes place: (a) on the principal market for the asset or liability; or (b) in the absence of a principal market, on the most advantageous market for the asset. Market participants. The fair value measurement measures the fair value of the asset or liability using the assumptions that the market participants would use in pricing the asset or liability, assuming that the participants act in their best economic interest. Prices. Fair value is the price that will be received for the sale of an asset or paid for the transfer of a liability in an orderly transaction on the main (or most advantageous) market as of the measurement date under current market conditions (i.e. Starting price) regardless of whether that price is directly observable or estimated using another valuation technique.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 198 Note 44 – Fair Value of Financial Assets and Liabilities, continued Highest and best use of non-financial assets. The fair value measurement of these assets takes into account the market participant’s ability to generate economic benefits through the highest and best use of the asset or through the sale of the asset to another market participant that would maximize the value of the asset. Bank’s own liabilities and equity instruments. The fair value measurement assumes that these items are transferred to a market participant on the date of measurement. The transfer of these items assumes that: a) A liability would remain outstanding and the market participant transferee would be required to fulfill the obligation. The liability would not be settled with the counterparty or otherwise extinguished on the measurement date. b) An entity’s own equity instrument would remain outstanding and the market participant transferee would take on the rights and responsibilities associated with the instrument. The instrument would not be canceled or otherwise extinguished on the measurement date. Default risk. The fair value of a liability reflects the effect of the default risk. This risk includes, but is not limited to, the entity’s own credit risk. This risk is assumed to be the same before and after the liability is transferred. Initial recognition. When an asset is acquired or a liability assumed in an exchange transaction involving that asset or liability, the transaction price is the price paid to acquire the asset or received to assume the liability (the entry price). In contrast, the fair value of the asset or liability is the price received to sell the asset or paid to transfer the liability (the exit price). Entities do not necessarily sell assets at the prices paid to acquire them. Likewise, they do not necessarily transfer liabilities at the price received to assume them. Valuation techniques. The Bank will use techniques that are appropriate for the circumstances and for which sufficient data is available to measure the fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. In this sense, the following approaches stand out, being the first two the most used by the group: a) Market approach Uses prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities, or a group of assets and liabilities. b) Income approach. Converts future amounts for example cash flows or income and expenses to a single current (discounted) amount, reflecting current market expectations about those future amounts. The fair value measurement is determined based on the value indicated by the current market expectations about those future amounts. c) Cost approach Reflects the amount that would be required currently to replace the service capacity of an asset (current replacement cost). Present value techniques. Technique to adjust the discount rate and expected cash flows (expected present value). The present value technique used to measure the fair value will depend on the specific facts and circumstances of the asset or liability being measured and the availability of sufficient data. Components of the present value measurement. Present value is the tool used to link future amounts (e.g. cash flows or values) to a present amount using a discount rate. A fair value measurement of an asset or a liability using a present value technique captures all the following elements from the perspective of market participants at the measurement date: a) An estimate of future cash flows for the asset or liability being measured.

Fair value hierarchy. It gives the highest priority to quoted prices (unadjusted) in active markets for identical assets and liabilities (Level 1 inputs) and lowest priority to unobservable inputs (Level 3 inputs).

The following section describes the methods used to estimate fair value: a) Measurement of the fair value of assets and liabilities for disclosure purposes (Non-recurring) Cash, short-term assets and short-term liabilities The fair value of these items approximates their book value given their short-term nature. These items include: - Cash and deposits in Banks - Cash in the process of collection - Financial instruments at fair value through profit or loss - Demand deposits and other demand obligations - Other financial obligations Loans The fair value of loans is determined using a discounted cash flow analysis. In the case of mortgage loans and consumer loans, the cash flows were discounted by using the effective average placement rate of the last month of the reporting period for each type of product. The fair value of commercial loans is determined using a discounted cash flow analysis, using a risk-free interest rate adjusted for expected losses from debtors based on their credit quality. The credit risk adjustment is based on variables observable in the market and the Group’s policies for qualitative and quantitative credit risk methodologies. This methodology was applied to: - Interbank loans - Loans and accounts receivable from customers Financial instruments at amortized cost The estimated fair value of these financial instruments is determined using quotes and transactions observed in the main market for identical instruments, or in their absence, for similar instruments. Fair value estimates of debt instruments or securities representative of debt take into account additional variables and inputs to the extent that they apply, including estimates of prepayment rates and the credit risk of issuers.

Medium and long-term liabilities include: - Term deposits and other term loans - Interbank borrowings - Debt instruments issued b) Value Measurement of financial assets and liabilities for recording purposes (recurring) Financial instruments The estimated fair value of these financial instruments is determined using quotes and transactions observed in the main market for identical instruments, or in their absence, for similar instruments. Fair value estimates of debt instruments or securities representative of debt take into account additional variables and inputs to the extent that they apply, including estimates of prepayment rates and the credit risk of issuers. These financial instruments are classified as follows: - Financial instruments held for trading at fair value through profit or loss - Financial instruments at fair value with changes in other comprehensive income Financial derivative contracts The estimated fair value of derivative instruments is calculated using prices quoted in the market for financial instruments with similar characteristics. The methodology recognizes the credit risk of each counterparty. The adjustment is known internationally as counterparty risk adjustment, which is composed of CVA (Credit Value Adjustment) and DVA (Debit Value Adjustment), the sum of both risk adjustments the effective counterparty risk that must be recognized. This adjustment is periodically recorded in the Interim Financial Statements.

The inputs needed to value the instruments in this category are available daily and used directly. In the case of Currency, Shares and Mutual funds, prices are observed directly in over-the-counter markets and the Stock Exchange. These prices correspond to the values at which the exact same assets are traded. As a result, the portfolio valuation does not require assumptions or models of any type. For instruments issued by the Chilean Central Bank and the Chilean Treasury, benchmark prices are used. Benchmark prices are defined using similar durations, type of currency and are traded the equivalent of every day. The valuation of these instruments is identical to the valuation of the Santiago Stock Exchange, which is a standard international methodology. This methodology uses the internal rate of return to discount the instrument’s cash flows.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 205 Note 44 – Fair Value of Financial Assets and Liabilities, continued Level 2 The specific instrument does not have daily quotes. However, similar instruments can be observed (e.g. same issuer, different maturity; or different issuer, same maturity and risk rating). In general, they are diverse combinations of pseudo-arbitration. Although the inputs are not directly observable, observable inputs are available with the needed periodicity. In this category, instruments are valued by discounting contractual cash flows based on a zero-coupon curve determined through the price of instruments with similar characteristics and a similar issuer risk. The income approach is used, which converts future amounts to present amounts. For derivative instruments within this category, quotes from other-the-counter transactions reported by the most important brokers in the Chilean market and the Bloomberg platform are used. The inputs observed include forward prices, interest rates and volatilities. Based on these inputs, market curves are modeled.They are a numerical representation of the opportunity costs of the instrument’s cash flows or the price volatility of an asset.Finally, cash flows are discounted. The Black and Scholes model is used for options based on prices of brokers in the OTC market. For money market instruments, prices of transactions on the Santiago Stock Exchange are observed and used to model market curves. For corporate or bank bonds, given the lack of market depth, the Bank uses transactions (if any) in the Chilean market, on foreign markets, zero-coupon curves of risk-free instruments, adjustment curves, spread modeling, correlation with similar financial instruments, etc. and gives market curves as the final result. These market curves are provided by a pricing supplier and are widely accepted by the market and its regulators. - Level 3 This is used when prices, data or necessary inputs are not directly or indirectly observable for similar instruments for the asset or liability as of the valuation date. These fair value valuation models are subjective in nature. Therefore, they base their estimate of prices on a series of assumptions that are widely accepted by the market. Due to the lack of liquidity in the basis of the active banking rate (TAB) over the chamber rate (camera), the price is not observable and, therefore, models must be used to estimate the future cash flows of the contract. This spread is calculated on a historical basis using the IRS with the greatest market depth, which is the chamber swap. In addition, the Bank offers American forwards to meet its customers’ needs. They do not have a secondary market and, therefore, their value is estimated using an extension of the Hull-White model, used widely by the financial services industry. With respect to financial assets, a negotiation is not required, mandatorily valued at fair value with changes in results, the valuation is made based on the determination of a rate that allows obtaining the fair value based on market references:

American forward options.  Financial assets whose contractual cash flows have not met the conditions of the SPPI test.  Corporate bond whose data are not observable in the market. As none of these products has a market, the Bank uses financial engineering valuation techniques that use unobservable variables. These techniques use as transaction prices from the main financial instrument markets and assumptions that are widely accepted by the financial services industry. Using this information, unobservable variables are constructed such as: adjustment curves, spreads, volatilities and other variables necessary for the valuation. Lastly, all of the models are subject to internal contrasts by independent areas and have been reviewed by internal auditors and regulators.

The American forward is only offered for the US dollar-Chilean peso market and until now, given the important differential between these interest rates, the product behaves like a traditional forward.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 217 Note 47 – Risk Management The Bank and its subsidiaries, through their activity, are exposed to several types of risk mainly related to loans portfolio and financial instruments. Risk management policies are established in order to identify and analyze the risks faced by the Bank, establish adequate limits and controls, monitor risks and comply with limits. Risk management policies and risk management structures are periodically reviewed to reflect changes in the institution’s activities. The Bank, through its rules and procedures, intends to develop an adequate control environment, in which all employees understand their functions and responsibilities. The main activities and policies of the Bank in terms of risk management are described below. (A) Risk Management Structure (i) Board of Directors In the Bank and its Subsidiaries, the Board of Directors plays a prominent role in corporate governance. It is responsible for establishing and monitoring the Bank’s risk management structure, for which it has a corporate governance system aligned with international best practices and Chilean regulations, mainly from the CMF. One of its main functions is to ensure the existence of measures that allow senior management to be supervised, evaluated and guided so that their actions are in line with best practices and defined levels of risk appetite. To this end, a governance structure has been created made up of various committees and internal standards. These committees and standards establish behavioral guidelines for the Bank’s employees and help them perform their functions related to risk control and management. (ii) Audit Committee The Audit Committee is responsible for monitoring the control environment and the effectiveness and efficiency of the company’s internal control systems as well as the compliance with regulations and internal standards, including oversight of the internal audit unit. The Audit Committee is also responsible for proposing to the Directors’ Committee a list of external auditors and risk rating agencies for the Bank and subsidiaries. In addition, the Audit Committee shall be responsible for supervising the different aspects that have to do with the maintenance, application and operation of the Bank’s internal controls, and shall be responsible also for closely monitoring compliance with the standards and procedures that govern its practice.

As of September 30, 2023 and December 31, 2022, the credit limit to 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 RAN are the following: As of September 30, As of December 31, 2023 2022 MCh$ % MCh$ % Global limit to groups of related people(1) 4,383,907 4,124,830 Use of the global limit for loans granted to groups of people related to the bank 126,920 2.90 89,467 2,17 (1) Corresponds to effective equity ii) Financial Risk x Market Risk Market Risk is the exposure to economic gains or losses caused by movements in prices and market variables. This risk stems from the activities of the Trading and Banking Books. In the first case, it comes from activities intended to obtain short-term gains and from the intensive use of fair value instruments. In the second case, with a more long-term vision, it stems from commercial activities with products valued at amortized cost. The following section describes the main market risk factors to which the Bank and its subsidiaries are exposed: x Currency Risk Currency risk is the exposure to adverse movements in the exchange rates of currencies other than their base currency (CLP in the case of operations in Chile and COP in the case of operations in Colombia) for all those positions inside and outside of balance. The main sources of exchange risk are: x Positions in foreign currency (MX) within the attributions of the Trading Book. x Currency mismatches between the assets and liabilities of the Banking Book. x Currency flow mismatches.

Changes in market interest rates can affect both the price of instruments recorded at fair value and the financial margin and other gains from the Banking Book such as fees. Fluctuations in interest rates also affect the Bank’s economic value. Interest rate risk can be represented by sensitivities to parallel and/or non-parallel yield shifts with the effects reflected in the prices of instruments, the financial margin, equity and economic value. The measurement of the structural interest rate risk is carried out through the representation by risk factor of the cash flows expressed in fair value, assigned on the dates of re-pricing and by currency. This methodology facilitates the detection of interest risk concentrations in the different terms. All the balance sheet and off balance sheet items are unbundled in their flows and placed at the re-pricing/maturity. In the case of those accounts that do not have a contractual maturity, an internal model of analysis and estimation of their durations and sensitivities is used. x Volatility Risk In addition to the exposure related to the underlying asset, issuing options has other risks. These risks arise from the non-linear relationship between the gain generated by the option and the price and level of the underlying factors, as well as exposure to changes in the price volatility of the underlying asset. x Liquidity Risk Liquidity Risk is the exposure of the Bank’s and its subsidiaries to events that affect their ability to meet, in a timely manner and at reasonable costs, cash payment obligations arising from maturities of time deposits that are not renewed, withdrawals from demand accounts, maturities or settlements of derivatives, liquidations of investments or any other payment obligation. Financial institutions are exposed to funding liquidity risk that is intrinsic to the role of intermediary that they play in the economy. In general, in financial markets demand for medium or long-term financing is usually much greater than the supply of funds for those terms while short-term financing is in considerable supply. In this sense, the role of intermediary played by financial institutions, which assume the risk of satisfying the demand for medium and long-term financing by brokering short-term available funds, is essential for the economy to function properly. Appropriately managing funding liquidity risk not only allows contractual obligations to be met in a timely manner, but also enables: x The liquidation of positions, when it so decides, to occur without significant losses.

The above implies an active monitoring of the risks, studying their temporal evolution. The risk management process can be subdivided into the following stages: x Financial Risks Identification The Financial Risk Management has a high-level technical team that constantly monitors the activities of the bank transfer and its subsidiaries in search of potential unquantified and controlled risks. In addition, the Bank Treasury as the first line of defense also plays a fundamental role in the detection of risks. Banco Itaú Chile provides a structure that facilitates this risk identification role by maintaining independence in its tasks and ensuring the active participation of management in the creation/ modification of products. x Quantification and Control of Exposure to Financial Risk Once all the risks have been identified, the Financial Risk Management is responsible for the quantification of the financial risk factors and the establishment of limits at different levels, according to the risk defined by the Board of Directors and the applicable regulations. The Financial Risk Management proposes a framework of quantitative and qualitative limits and alerts that are reviewed and approved by the ALCO and the Board of Directors. Additionally, it periodically measures the risk incurred, develops valuation tools and models, performs periodic stress analyses, measures the degree of concentration with interbank counterparties, prepares the manual of policies and procedures, as well as monitoring authorized limits and alerts, which are reviewed at least annually. The metrics, by type of risk, used to quantify exposures are explained below: x Market Risk Metrics and Limits for the Trading and Banking Portfolio The Bank´s measures regulatory exposures in line with the standardized methodologies established by the Central Bank (Chapter III B-2 Standard of measurement and control of market risk for Banks", of the Compendium of Financial Regulations), supplemented by the CMF in Chapter 12-21 of the RAN, which correspond to the methodologies standardized by the Basel Committee to quantify the market risk exposures of the Trading and Banking Books. The regulatory measurements of the trading book allow estimating the potential loss that the Bank could face given the fluctuations according to the shocks defined by the regulator. The regulatory limit corresponds to the sum of these risks (also called Market Risk Exposure “MRE”) and 10% of the Assets Weighted by Credit Risk, a sum that cannot exceed the Bank's Effective Equity in any case.

Below is the consumption of the regulatory market risk limit, specifically for the Trading Portfolio as of September 30, 2023 and December 31, 2022. As of September 30, As of December 31, Limit Consumer 2023 2022 % % Market risk exposure (MRE) 57,74 58,66 The measurement of regulatory risk for the Banking Portfolio is used to estimate the Bank’s potential losses from standardized adverse movements in interest and exchange rates. The standardized regulatory report for the Banking Portfolio is used to estimate the Bank's potential economic losses due to standardized adverse movements in interest rates defined by the CMF. Currently, the short-term exposure limits (STE) to interest rate and indexation risk in the Banking Portfolio must not exceed 35% of the annual operating income (LTM rolling period) and the consumption of long-term limits (LTE) must be less tan 20% of the Bank's regulatory capital. The following table details the regulatory limit consumption by market risk of the Banking Book, considered as the percentage limit to be calculated based on the regulations indicated above as of September 30, 2023, while the measurement based on Chapter 12-21 of the RAN (1) is maintained for December 31, 2022. As of September 30, As of December 31, Limit Consumer 2023 2022 % % Short-term exposure to interest rate risk 21.66 32.62 Long-term exposure to interest rate risk 16.19 6.45 As of September 30, 2023 and December 31, 2022, the Bank has complied with all regulatory requirements and limits, as well as with all financial covenants, such as risk-weighted capital adequacy ratio, single borrower exposure, aggregate exposure, concentration risk, equity to asset ratio, provision coverage ratio, among others.

This measurement provides the maximum potential economic loss at a certain confidence level and a given time horizon. Historical VaR, as opposed to Statistical or Parametric VaR, is based on the observed distribution of past returns, does not need to make assumptions of probability distributions (frequently normal distribution) and, therefore, does not need a mean (assumed 0), standard deviation and correlations across returns (parameters). The Bank's uses a 99% confidence level and a time horizon of 1 day. x Calculation of Volatility-Adjusted Historical Value at Risk (Non-parametric). This measurement is based on the above and the profit and loss vector is adjusted according to whether it is facing a period of greater or less volatility. The Board of Directors and senior management define the limits on the Value at Risk, which is monitored on a daily basis. In turn, the measurement is subjected to retrospective tests that allow verifying that the losses actually incurred do not exceed the VaR, more than once every 100 days. The result is monitored daily to test the validity of the assumptions, hypotheses and the adequacy of the parameters and risk factors used in the calculation of the VaR. The Bank calculates the VaR for sub-portfolios and risk factors, which allows it to quickly detect sources of risk. Since the VaR does not take into account stress scenarios, it is complemented with stress tests taking into account prospective, historical and standardized scenarios. Although the VaR is one of the most frequently used models by the local financial industry, and considering that it is a model, as such it has limitations that must be considered: x It does not take into account the expected loss in the event that the return on the portfolio is above the confidence level defined in the VaR. That is, in the case of the Bank it does not reflect what happens in the 1% of the queue. This is mitigated with the stress measures detailed below. x It does not consider intraday results, but only reflects the potential loss given current positions. x It does not take into account the potential changes in the dynamics of the movements of the market variables (that is, the possible changes in the variance and covariance matrix). Sensitivity measures The Bank uses stress tests as a sensitivity analysis tool to control financial risk. This measurement is performed separately for the trading and banking portfolios. The sensitivity is estimated using the DV01 indicator, which corresponds to a measure of sensitivity of the portfolio results if the zero coupon interest rate of the risk factor increases by 1 basis point (0.01%) for different maturities and in annualized terms. In accordance with IFRS 7, it in presented an estimate of the likely, but reasonable, impact of fluctuations in interest rates, exchange rates and implied volatilities (market factors) that would affect the trading and banking portfolios.

To estimate the sensitivity, the sensitivity (DV01) and the reasonably probable scenarios are multiplied by the market factor. Interest rate scenarios - Chile (basis points - 0.01%) The interest rate shock scenarios on income accounting average -689 basis points in the case of the CLP chamber. An average of +474 basis points for CLF chamber and government factors (CLF y CLP) and -515 for US dollar and other currency factors. In the case of interest rate shock associated with fair value accounting in other comprehensive income, this shock averages +689 basis points in the case of the CLP chamber factor, -349 basis points for CLF chamber and +471 for the rest of the yields. Interest rate scenarios Colombia (basis points - 0.01%) Interest rate shock scenarios on income accounting and fair value accounting in other comprehensive income average +43 basis points for all yields. Chile exchange rate scenarios As of September 30, 2023, for the exchange rate impact scenarios, both in profit or loss, fair value accounting in other comprehensive income and equity, the worst result shock would imply a change of +17.80% in the Chilean peso-US dollar parity, and -11.23% in the COP-US dollar parity. As of December 31, 2022, for the exchange rate impact scenarios, both in profit or loss, fair value accounting in other comprehensive income and equity, the worst result shock would imply a change of +24.75% in the Chilean peso-US dollar parity, and -7.23% in the COP-US dollar parity. Colombia exchange rate scenarios As of September 30, 2023, for the exchange rate impact scenarios, both in profit or loss, fair value accounting in other comprehensive income and equity, the worst result shock would imply a change of +2.91% in the COP-US dollar parity. As of December 31, 2022, for the exchange rate impact scenarios, both in profit or loss, fair value accounting in other comprehensive income and equity, the worst result shock would imply a change of +5.64% in the COP-US dollar parity.

In the case where the hedging instrument is subject to an accounting treatment different from the exposure of the underlying object of coverage, the Bank may use the accounting hedge treatment to eliminate the accounting asymmetries that could generate undue volatility in the results and/or Bank assets. The use of accounting hedges is subject to the limits defined by the Board of Directors, to the definitions of the Financial Management and Market Higher Commission (ALCO) and to the Hedging Policy. The Treasury is responsible for designing and implementing the strategies, the Financial Risk Management is responsible for measuring and monitoring the effectiveness of the hedges, generating effectiveness indicators that are constantly monitored, and the Financial Control Management is responsible for qualifying adequate regulatory compliance. In the case of accounting hedges (For more details on accounting hedge strategies, review Note 12 “Derivative contracts for accounting hedges”). Operational Risk The Bank and its subsidiaries define operational risk as the possibility of occurrence of losses resulting from failures, deficiencies or inadequacies in internal processes, people, and systems or external events, including in this definition the legal risk and excluding strategic risks and reputation. Operational risk is recognized as a manageable risk, for which it has defined a function in charge of this task within its corporate structure. The Bank adopts a model of three lines of defense as the primary way to implement its operational risk management structure, internal controls and compliance, ensuring compliance with corporate guidelines. The defense lines are composed by; the business and support areas (first line of defense) responsible for managing the risks related to their processes; Operational Risk, Internal Control, and the area of AML and Compliance (second line of defense) area in charge of supporting the first line of defense in relation to the fulfillment of its direct responsibilities; and Internal Audit function (third line of defense) responsible for verifying, independently and periodically, the adequacy of the risk identification and management processes and procedures, in accordance with the guidelines established in the Internal Audit Policy and submitting the results of its recommendations for improvement to the Audit Committee. The risk management program contemplates that all relevant risk issues must be reported to the higher levels and to the Operational Risk Higher Commission. Our methodology consists in the evaluation of the risks and controls of a business from a broad perspective and includes a plan to monitor the effectiveness of such controls and the identification of eventual weaknesses. The main objectives of the Bank and its subsidiaries in terms of operational risk management are the following: x Identification, evaluation, information, management, and monitoring of the operational risk in connection with activities, products, and processes carried out or commercialized by the Bank and its subsidiaries;

Regarding training and awareness, the risk culture continues to be reinforced through face-to-face training in the field of operational risk, internal control, prevention of external and internal fraud, and the implementation of the annual "more security" program for all collaborators and induction programs for new employees. Finally, it is worth mentioning that Sarbanes-Oxley methodologies (SOX) continue to be applied for their main products and processes, the application of this methodology is annually certified by an external consultant.

Banco Itaú Chile and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2023 and December 31, 2022 and for the three and nine months periods ended as of September 30, 2023 and 2022 Banco Itaú Chile and subsidiaries – Interim Consolidated Financial Statements– September 30, 2023 239 Note 48 - Information on Regulatory Capital and Capital Adequacy Indicators The primary objectives of the Bank's capital management are to ensure compliance with regulatory requirements, maintain a strong credit rating and healthy capital ratios. During the periods ended as of September 30, 2023 and as of December 31, 2022, the Bank has fully complied with the capital requirements. In January 2019, Law No. 21,130 was issued, which modernizes the banking legislation with the objective of implementing the practices promoted at international level by the Basel III agreement, introducing amendments to the General Banking Law (hereinafter "GBL"). In order to implement the standards, the Financial Market Commission initiated the regulatory process for their implementation by incorporating amendments and new chapters to the Updated Compilation of Standards (hereinafter "RAN"). The application of the regulatory adjustments and exclusions from the capital base will be gradual, in accordance with the transitional provisions of Chapter 21-1, starting with a 15% discount on December 1, 2022, rising to 30% as of December 1, 2024, to 65% as of December 1, 2024, and reaching 100% as of December 1, 2025. Assets are weighted according to risk categories as established in Chapter 21-6 "Determination of assets weighted by credit risk", Chapter 21-7 "Determination of assets weighted by market risk" and Chapter 21-8 "Standardized methodology for the computation of assets weighted by operational risk". All derivative instruments traded outside of stock exchanges are considered in the determination of risk assets with a conversion factor on the notional values, thus obtaining the amount of exposure to credit risk (or "credit equivalent"). Off-balance sheet contingent credits are also considered as "credit equivalent" for their weighting, in accordance with the provisions of Chapter 21-6 of the RAN. Regarding its implementation, the new regulation for solvency measurement purposes and regulatory minimum requirements will be effective as of December 1, 2021 and will be implemented gradually until it is fully established as of December 1, 2025. In December 2022, the additional capital requirement to which Banco Itaú was subject under the transitory provisions of RAN 12-14 "Application of Article 35 BIS of the General Banking Law (GBL)" was repealed, due to its merger.
