INDEPENDENT AUDITOR'S REVIEW REPORT (A free translation from the original in Spanish) Santiago, October 26, 2022 To the Shareholders and Directors Itaú Corpbanca We have reviewed the accompanying interim consolidated statement of financial position of Itaú Corpbanca and subsidiaries as of September 30, 2022, the interim consolidated statements of income and of other comprehensive income for the three-month and nine-month periods ended September 30, 2022 and 2021, and the related interim consolidated statements of cash flows and of changes in equity for the nine-month periods then ended, and the related notes to the interim consolidated financial statements. Management's Responsibility for the Interim Consolidated Financial Statements Management is responsible for the preparation and fair presentation of the interim consolidated financial statements in accordance with accounting standards and instructions issued by the Commission for the Financial Market. This responsibility includes the design, implementation, and maintenance of internal control sufficient to provide a reasonable basis for the preparation and fair presentation of the interim consolidated financial statements in accordance with the applicable framework for preparation and presentation of financial information. Auditor's Responsibility Our responsibility is to conduct our review in accordance with auditing standards generally accepted in Chile applicable to reviews of interim financial information. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. The scope of a review, is substantially less than an audit conducted in accordance with auditing standards generally accepted in Chile, the objective of which is the expression of an opinion regarding the financial information. Accordingly, we do not express such an opinion. Conclusion Based on our reviews, we are not aware of any material modifications that should be made to the interim consolidated financial statements, mentioned in the first paragraph, to be in accordance with accounting standards and instructions issued by the Commission for the Financial Market.

Itaú Corpbanca and subsidiaries Notes to the Interim Consolidated Financial Statements As of September 30, 2022, December 31, 2021 and January 1, 2021 and for the three and nine-month periods ended September 30, 2022 and 2021 Itaú Corpbanca and subsidiaries– Interim Consolidated Financial Statements– September 30, 2022 13 Note 2 - Summary of Significant Accounting Policies, continued (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. The following entities are considered “Associated entities”, in which the Bank has participation and are accounted for by applying the equity method, according to IAS 28 “Investments in Associates and Joint Ventures”. Name of the Main Activity Place of operation As of September 30, 2022 As of December 31, 2022 As of January 01, 2021 Associates % interest % interest % interest Nexus S.A.

As a result, these assets were reclassified as “Available for Sale”. This transaction was completed as of September 30, 2022, and as a result Itaú Corpbanca ceased to be a shareholder of Nexus (See note 5). (2) As of the second quarter of 2021, the Bank gained significant influence over Sociedad Operadora de la Cámara de Compensación de Pagos de Alto Valor S.A. (hereinafter, “Combanc S.A.”) and over Servicios de Infraestructura de Mercado OTC S.A. (hereinafter, “Imerc OTC S.A.”). Management concluded that, because of fact that the Bank can elect one of the members of the Board of Directors in each of these entities, in addition to other factors, such as significant transactions between the Bank and these entities, exchange of essential technical information with its investees and other factors, the Bank has a say in the financial and operating decision-making of these investees, but does not control them. Consequently, the equity method has been applied. (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 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.

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 "LGB"), 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, Finally, on March 30, 2022, the Financial Market Commission (CMF in Spanish) informed the Bank of the result obtained in its annual review, in order to qualify the quality of a systemic bank at the local level, The Board of the CMF, with the prior favorable agreement of the Central Bank of Chile, determined to maintain Itaú Corpbanca's rating as systemically important, determining in this regard a basic capital requirement on risk-weighted assets of 1%, in addition to the general minimum requirement of the article 66 of the LGB, As indicated in Chapter 21-1 of the RAN and the fifth transitory article of Law No, 21,130, the assigned position must be constituted by 25% no later than December 1, 2022. In accordance with the General Banking Law (LGB), the Bank must maintain a minimum ratio of Cash Equity to Consolidated Risk-Weighted Assets of 8% in accordance with article 66 of the LGB, In addition to the above, it must maintain an additional core capital equivalent to 0,625% of its risk-weighted assets in accordance with article 66 bis of the General Banking Law, net of required provisions, and a minimum ratio of Core Capital to Total Consolidated Assets of 3%, net of required provisions, However, as of the Bank's merger, the regulator determined that the resulting Bank's Cash Equity must consider an additional 2,0%, which in accordance with the transitory provisions of RAN 12-14 “Application of article 35 BIS of the General Banking Law” must be constituted in 75% as of December 1, 2021, Therefore, the Bank must maintain a minimum ratio of Capital Stock to Risk-Weighted Consolidated Assets of 10,13%, For purposes of determining these indicators, the Bank has applied the provisions of Chapter 21-1 "Shareholders' Equity for legal and regulatory purposes" of the RAN.
