NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS
As of September 30, 2026 and 2025 and December 31, 2025

Banco de Chile (“The Bank”) has been authorized to operate as a commercial bank since September 17, 1996, being, in conformity with the stipulations of article 25 of Law No. 19,396, the legal successor of Banco de Chile resulting from the merger of the Banco Nacional de Chile, Banco Agrícola and Banco de Valparaiso, which was incorporated by public deed dated October 28, 1893, granted before the Notary Public of Santiago, Mr. Eduardo Reyes Lavalle, and authorized by Supreme Decree of dated November 28, 1893.

The Bank is a Corporation organized under the laws of the Republic of Chile, regulated by the Chilean Commission for the Financial Market (“CMF”). Since 2001, it is subject to the supervision of the Securities and Exchange Commission of the United States of America (“SEC”), in consideration of the fact that the Bank is registered on the New York Stock Exchange (“NYSE”), through a program of American Depositary Receipt (“ADR”).

Banco de Chile offers a broad range of banking services to its customers, ranging from individuals to large corporations. Additionally, the Bank offers international as well as treasury banking services, in addition to those offered by subsidiaries that include securities brokerage, mutual fund and investment management, insurance brokerage and financial advisory services.

Banco de Chile’s registered office is located at Ahumada 251, Santiago, Chile and its website is www.bancochile.cl.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

Decree Law No. 3,538 of 1980, according to the text superseded by the first article of Law No. 21,000 that “Creates the Financial Market Commission”, provides in number 6 of its article 5 that the Financial Market Commission (“CMF”) may “set the standards for the preparation and presentation of reports, balance sheets, statements of situation and other financial statements of the audited entities and determine the principles under which they must keep their accounting records”.

According to the current legal framework, banks must use the accounting principles established by the CMF and in everything that is not dealt with by it or in contravention of its instructions, they must adhere to the generally accepted accounting principles, which correspond to the technical standards issued by the Colegio de Contadores de Chile A.G., coinciding with the Accounting Standards of International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”). Should any discrepancy exist between accounting principles generally accepted in Chile and the accounting standards issued by the CMF, the latter shall prevail.

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

The Interim Consolidated Financial Statements of Banco de Chile for the period ended September 30, 2026 and 2025 and December 31, 2025, have been consolidated with its subsidiaries. The Interim Consolidated Financial Statements have been prepared using consistent accounting policies for similar transactions and other events, in equivalent circumstances.

Significant intercompany transactions and balances (assets and liabilities, equity, income, expenses and cash flows) generated from operations performed between the Bank and its subsidiaries have been eliminated in the consolidation process. The non-controlling interest corresponding to the participation percentage of third parties in subsidiaries, which the Bank does not own directly or indirectly, has been recognized and is shown separately in the consolidated shareholders’ equity and consolidated income statement of the Bank.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

Interim Consolidated Financial Statements for the period ended September 30, 2026 and 2025 and December 31, 2025 include the Financial Statements of the Bank and its subsidiaries in accordance with IFRS 10 “Consolidated Financial Statements”.

The entities controlled by the Bank and consolidated are detailed as follows:

Associated entities are those over which the Bank has the ability to exercise significant influence, without having control over the associate.

Investments in associates where the entity has significant influence are accounted for using the equity method of accounting (Note 14 Investments in other companies).

Joint Ventures are joint arrangements whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Joint control exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control.

Investments defined as a “Joint Venture” are recognized using the equity method of accounting.

The investment in other companies that, for its characteristics, is defined as “Joint Venture” is Servipag Ltda.

On initial recognition, the Bank and subsidiaries may make an irrevocable election to present in other comprehensive income subsequent changes in the fair value of an investment in an equity instrument that is not held for trading and is not contingent consideration recognized by an acquirer in a business combination to which IFRS 3 is applied.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

The Bank and its subsidiaries manage and administer assets held in mutual funds and other investment products on behalf of investors, receiving compensation in line with the services provided and in accordance with market conditions. Managed resources are owned by third parties and, therefore, not included in the Consolidated Statements of Financial Position.

In accordance with IFRS 10, for consolidation purposes it is necessary to assess the role of the Bank and its subsidiaries with respect to the funds they manage, to determine whether that role is Agent or Principal.

The Bank and its subsidiaries manage investments and mutual funds on behalf and for the benefit of investors, acting only as an Agent in this relationship. Under this category, and as per the aforementioned regulation, it does not control such funds when exercising their authority to make decisions. Accordingly, as of September 30, 2026 and 2025 acting as agents, are not controlled and therefore not consolidated by the Bank or its subsidiaries.

Non-controlling interest represents the share of losses, income and net assets that the Bank does not control, either directly or indirectly. It is presented as a separate item in the Consolidated Statements of Income and the Consolidated Statements of Financial Position.

The preparation of Interim Consolidated Financial Statements requires Management to make judgments, estimations and assumptions that affect the application of accounting policies and the valuation of assets, liabilities, income and expenses presented. Actual results could differ from these estimated amounts. The estimates made refer to:

Estimates and relevant assumptions are regularly reviewed by Management in order to quantify certain assets, liabilities, revenue, expenses and commitments.

During the period ended September 30, 2026, there have been no significant changes in the estimates made.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

The classification, measurement and presentation of financial assets has been performed based on the standards issued by the CMF in the Compendium of Accounting Standards for Banks or “CNCB” (per its Spanish acronym), considering the criteria described below:

Classification of financial assets:

On initial recognition, a financial asset is classified within the following categories: Financial assets held for trading at fair value through profit or loss; Non-trading financial assets mandatorily measured at fair value through profit or loss; Financial assets designated as at fair value through profit or loss; Financial assets at fair value through other comprehensive income and Financial assets at amortized cost.

The criteria for classifying financial assets, which includes the standards defined in IFRS 9, depends on the business model with which the entity manages the assets and the contractual characteristics of the cash flows, commonly known as the “Solely Payments of Principal and Interest” (SPPI) criterion.

The measurement of these assets should reflect how the Bank manages groups of financial assets and does not depend on the intent for an individual instrument.

A financial asset shall be measured at amortized cost if both of the following conditions are met:

A financial asset shall be measured at fair value through other comprehensive income if the following two conditions are met:

A financial asset will be classified at fair value through profit or loss whenever, due to the business model or the characteristics of its contractual cash flows, it is not appropriate to classify it in any of the other categories described above.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

Measurement of financial assets:

Initial recognition:

Financial assets are initially recognized at fair value plus, in the case of a financial asset that is not carried at fair value through profit or loss, the transaction costs that are directly attributable to its acquisition or issuance, using the Effective Interest Rate method (EIT). The calculation of the effective interest rate includes all fees, commissions and other items paid or received that are part of the effective interest rate. Transaction costs include incremental costs that are directly attributable to the acquisition or issuance of a financial asset.

Subsequent measurement:

All variations in the value of financial assets due to the accrual of interest and items treated as interest are recorded in “Interest income” or “Interest expense” of the Consolidated Statement of Income for the year in which the accrual occurred, except for trading derivatives that are not part of accounting hedges.

Changes in the valuations that occur subsequent to initial registration for reasons other than those mentioned in the preceding paragraph, are treated as described below, based on the categories in which the financial assets are classified.

Financial assets held for trading at fair value through profit or loss, Non-trading financial assets mandatorily measured at fair value through profit or loss and financial assets designated as at fair value through profit or loss:

The caption “Financial assets held for trading at fair value through profit or loss” will record financial assets whose business model aims to generate profits through purchases and sales or to generate results at short-term.

The financial assets recorded under “Non-trading Financial assets 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 where the cash flows contracts have not met the conditions of the SPPI test.

The caption “Financial assets designated as at fair value through profit or loss” will classify financial assets only when such designation eliminates or significantly reduces the inconsistency in the measurement or in the recognition that would arise from valuing or recognizing the assets on a different basis.

The assets recorded in these items are valued after their acquisition at their fair value and changes in their value are recorded, at their net amount, under “Financial assets and liabilities held for trading”, “Non-trading financial assets and liabilities mandatorily measured at fair value through profit or loss” and “Financial assets and liabilities designated as at fair value through profit or loss” of the Consolidated Statement of Income. Variations originated from differences are recorded under “Foreign currency changes, UF indexation and accounting hedge” in the Consolidated Statement of Income.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

Financial assets at fair value through other comprehensive income:

The assets recorded in this item are measured at their fair value, interest income and indexation of these instruments, as well as exchange differences and impairment arising, are recorded in the Consolidated Statement of Income, whereas subsequent variations in their valuation are temporarily recorded (for its amount net of taxes) in “Changes in the fair value of financial assets at fair value through other comprehensive income” of the Consolidated Statements of Other Comprehensive Income.

The amounts recorded in “Changes in the fair value of financial assets at fair value through other comprehensive income” continue to be part of the Bank’s consolidated equity until the asset is derecognized in the consolidated balance. Should these assets be sold, the resulting gain or loss is recognized in “Financial result for derecognizing financial assets and liabilities at amortized cost and financial assets at fair value through other comprehensive income” in the Consolidated Statement of Income.

Net impairment losses on financial assets at fair value through other comprehensive income occurred during the year are recorded in “Impairment due to credit risk of other financial assets at amortized cost and financial assets at fair value through other comprehensive income” in the Consolidated Statement of Income.

On initial recognition, the Bank may make the irrevocable decision to present subsequent changes in fair value in other comprehensive income. Subsequent variations in this valuation will be recognized in “Changes in fair value of equity instruments designated as at fair value through other comprehensive income.” The dividends received from these investments are recorded in “Income from investments in companies” in the Consolidated Statement of Income. These instruments are not subject to the impairment model of IFRS 9.

The assets recorded in this item of the Consolidated Statement of Financial Position are measured after their acquisition at their “amortized cost”, in accordance with the effective interest method. They are subdivided according to the following:

Losses due to impairment of these assets generated in each year are recorded in “Provisions for credit risk of loans to banks and loans to customers” and “Impairments for credit risk of other financial assets at amortized cost and financial assets at FVTOCI” in the Consolidated Statement of Income.

 NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

Resale agreement operations are carried out as a form of investment. Under these agreements, financial instruments are purchased, which are included as assets in “Rights by resale agreements” which are valued according to the interest rate of the agreement through the amortized cost method. In accordance with current regulations, the Bank does not record as its own portfolio those papers purchased under resale agreements.

Repurchase agreement operations are also performed as a form of financing, which are included as liabilities in “Obligations by repurchase agreements”. In this regard, the investments that are sold subject to a repurchase obligation and that are used as collateral for the loan correspond to financial debt securities. The obligation to repurchase the investment is classified in liabilities as “Obligations by repurchase agreements” and is measured according to the interest rate of the agreement.

These instruments are recorded at their cost plus accrued interest and UF indexation, less the allowances for impairment made when their recorded amount is higher than the estimated amount of recovery and their interest and UF indexation of debt financial instrument at amortized cost are included in “Interest income” and “UF indexation income”.

This item shows the balances of operations with local and foreign banks, including the Central Bank of Chile and foreign Central Banks.

Loans from customers include generated and acquired relate to non-derivative financial assets with fixed or determinable payments that are not quoted in an active market and which the Bank does not intend to sell immediately or in the short-term.

They are initially measured at cost plus incremental transaction costs and income, and subsequently measured at amortized cost, using the effective interest rate method, less any impairment loss, except when the Bank defines certain loans as hedged items, measured at fair value through profit or loss as described in letter (p) of this note.

These are included under the item “Loans to customers” correspond to regular lease payments for contracts which meet the definition to be classified as financial leases and are presented at their nominal value net of unearned interest as of each year-end.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

They are measured for the amounts disbursed by the Bank in exchange for invoices or other commercial instruments representing credits, with or without responsibility of the grantor, received in discount. Price differences between the amounts disbursed and the nominal value of the credits are recorded in profit or loss as interest income, through the effective interest method, during the financing period. In those cases where the transfer of these instruments was made without responsibility of the grantor, the Bank assumes the insolvency risks of those required to pay.

The Bank permanently evaluates the entire portfolio of loans and contingent loans, with the aim of establishing the necessary and sufficient provisions in a timely manner to cover the expected losses associated with the characteristics of the debtors and their credits, based on the payment and subsequent recovery.

Allowances are required to cover the risk of loan losses have been established in accordance with the instructions issued by the CMF. The loans are presented net of those allowances and, in the case of contingent loans are shown in liabilities under the item “Special provisions for credit risk”

In accordance with CMF’s instructions, models or methods are used based on an individual and collective analysis of debtors, to establish the allowance for loan losses. The Bank’s Board of Directors approves such models, as well as the amendments to their design and application.

An individual analysis of debtors is applied to companies that are of such significance with respect to size, complexity or level of exposure to the bank, that they must be analyzed in depth.

Likewise, the analysis of borrowers focuses on its creditworthiness related to the capacity and willingness to meet their credit obligations, through sufficient and reliable information, and should also be analyzed with respect to guarantees, terms, interest rates, currency and indexation, etc.

For the purposes of establishing the allowances, banks must assess the creditworthiness and classify debtors and their transactions referred to contingent loans, in the related categories with the prior allocation to one of the following three portfolio categories: Normal, Substandard and Non-performing loans.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

Normal performing loans: includes those debtors whose payment capacity allows them to meet their obligations and commitments, and according to the evaluation of their economic and financial position no change in this condition are displayed. Loans classified in categories A1 through A6.

Substandard loans: includes all borrowers with insufficient payment capacity or significant deterioration of payment capacity that may be reasonably expected not to comply with all principal and interest payments obligations set forth in the credit agreement, showing a low flexibility to meet its financial obligations at short-term.

The Substandard Portfolio also includes those debtors who have shown past due amounts over 30 days recently. The classifications assigned to this portfolio are categories B1 to B4 of the rating scale.

As a result of individual analysis of the debtors, the Bank must classify them in the following categories, assigning, subsequently, the percentage of probability of default and loss given default resulting in the following percentage of expected loss:

Allowances for Normal and Substandard Loans:

To determine the amount of allowances to be made for normal and substandard portfolios, the exposure subject to the allowances should be estimated previously, applying the related loss percentages, which consist of probability of default (PD) and loss given default (LGD) established for the category in which the debtor and/or guarantor belong, as appropriate.

The exposure subject to allowances relates to loans plus contingent loans minus the amounts to be recovered by way of the foreclosure of financial or real guarantees of the operations. Loans mean the carrying amount of loans and accounts receivable of the related debtor, whereas for contingent loans, the value resulting from applying that indicated in No. 3 of Chapter B-3 of the CNCB.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

For real guarantees, the Bank must demonstrate that the value assigned to this deduction reasonably reflects the value that it would obtain from the sale of the assets or equity instruments. Also, in qualifying cases, the direct debtor’s credit risk may be substituted for the creditworthiness of the guarantor. In no event may the guaranteed securities be discounted from the amount of the exposure, as this procedure is only applicable when related to financial or real guarantees.

For calculation purposes, the following must be considered:

Provision debtor = (ESA-GE) x (PDdebtor /100) x (LGDdebtor /100) + GE x (PDguarantor /100) x (LGDguarantor /100)

Where:

However, the Bank must maintain a minimum provision level of 0.50% over normal portfolio and contingent loans.

The non- performing portfolio includes the debtors and their loans whose recovery is considered remote, as they show impaired or no payment capacity. This category comprises all debtors who have stopped paying their creditors or with visible evidence that they will stop doing so, as well as those for which a forced restructuring of their debts is necessary, reducing the obligation or postponing the payment of the principal or interest and, in addition, any debtor that has 90 days overdue or more in the payment of interest or principal of any loan. This portfolio is composed of the debtors belonging to categories C1 to C6 of the rating scale and all loans, including 100% of the amount of contingent loans, held by those same debtors.

For purposes recognizing the allowances on non- performing loans, the Bank has allowance percentages to be applied to the amount of exposure, which relates to the amount of loans and contingent loans kept by the same debtor. To apply that percentage, an expected loss rate must be estimated, deducting from the exposure amount the recoverable amounts through the execution of financial or real guarantees supporting the transaction and, in the event specific background substantiate it, deducting the present value of recoveries that may be obtained performing collection actions, net of expenses associated with them. Such loss percentage must be categorized in one of the six levels defined by the range of expected actual losses by the Bank for all transactions from the same debtor.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

These categories, their loss range as estimated by the Bank and the percentages of allowances that must be applied on the amount of exposures, are listed in the following table:

For calculation purposes, the following must be considered:

Where:

All of the loans debtors must remain in the Default Portfolio until there is a normalization of their capacity or payment behavior, without prejudice to punishment of each particular credit that meets the condition indicated in Title II of Chapter B-2 of the Compendium of Accounting Standards for Banks. To remove a debtor from the Default Portfolio, once the circumstances that lead to classification in this portfolio according to these regulations have been overcome, at least the following cumulative conditions must be met:

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

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

Banks must maintain a complete and permanent monitoring of all operations with entities belonging to business groups. Considering the potential costs of forming groups for all debtors, the bank must at least maintain control and forming groups, if applicable, for all debtors who maintain a current exposure greater than a minimum amount established by the banking institution which may not be greater than 1% of its effective equity at the time the definition of the group portfolio is made.

For the remaining commercial credit exposures, the individual analysis model of the debtors must be applied.

The determination of the type of analysis (group or individual) must be carried out at the global consolidated level, once a year, or after significant adjustments in the Bank’s portfolio, such as mergers, acquisitions, purchases or significant portfolio sales.

To determine allowances, group assessment requires the creation of loan groups with similar characteristics in terms of debtors types and agreed terms, to establish technically based estimates by prudential criteria and following both the payment behavior of the group in question and the recoveries concerned of defaulted loans and consequently provide the necessary provisions to cover the portfolio risk.

To determine its allowances, the Bank segments its debtors into homogeneous groups, according described above, associating to each group with a determined probability of default and a recovery percentage based in a historic analysis. The amount of provisions to register it will be obtained multiplied the total loans of respective group by the percentages of estimated default and of loss given the default, the estimated losses must be related to the type of portfolio and the term of the operations.

The Bank discriminates between provisions on the normal portfolio and on the portfolio in default, and those that protect the risks of contingent credits associated with those portfolios.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

The standard methodologies presented below establish the variables and parameters that determine the provision factor for each type of portfolio that the CMF has defined as representative, according to the common characteristics shared by the operations that comprise them.

The provision factor applicable, represented by expected loss over the mortgage loans, will depend on the past due of each credit and the relation, at the end of month, between outstanding capital and the value of the mortgage collateral (PVG), according to the following table:

Where:

To determine these allowances, the Bank considers the standard methods presented below, as applicable to commercial leasing operations or other types of commercial loans. Then, the applicable provision factor will be assigned considering the parameters defined for each method.

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS, continued

The provision factor applies to the current value of commercial leasing operations (including the purchase option) and will depends on the default of each operation, the type of leased asset and the relationship between the current value of each operation and the leased asset value (PVB) at each month-end, as indicated in the following tables:

The determination of the PVB relationship is made considering the appraisal value expressed in UF for real estate and in Chilean pesos for non-real estate, recorded at the time of the respective loan granting, taking into account possible situations that may be causing temporary increases in the assets prices at that time.
