Independent Auditor’s Report

(English Translation of a Report Originally Issued in Korean)

To the Board of Directors and Shareholders of Kookmin Bank

Opinion

We have audited the consolidated financial statements of Kookmin Bank and its subsidiaries (collectively referred to as the “Group”) which comprise the consolidated statements of financial position as at December 31, 2025 and 2024, and the consolidated statements of comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows for the years then ended, and notes to the consolidated financial statements, including material accounting policy information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as at December 31, 2025 and 2024, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS).

Basis for Opinion

We conducted our audits in accordance with Korean Standards on Auditing. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Group in accordance with the ethical requirements of the Republic of Korea that are relevant to our audit of the consolidated financial statements and we have fulfilled our other ethical responsibilities in accordance with the ethical requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Other Matter

Auditing standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to audit such consolidated financial statements may differ from those generally accepted and applied in other countries.

Responsibilities of Management and Those Charged with Governance for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with Korean IFRS, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Group or to cease operations.

Those charged with governance are responsible for overseeing the Group’s financial reporting process.

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Korean Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with Korean Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

•	Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to<br>fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is<br>higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
•	Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are<br>appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control.
---	---
•	Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and<br>related disclosures made by management.
---	---
•	Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on<br>the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are<br>required to draw attention in our auditor’s report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up<br>to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to continue as a going concern.
---	---
•	Evaluate the overall presentation, structure and content of the consolidated financial statements, including the<br>disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
---	---
•	Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business<br>activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the Group audit. We remain solely responsible for our audit opinion.<br>
---	---

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

1. Reporting Entity

Kookmin Bank (the “Bank”) was incorporated in 1963 under the Citizens National Bank Act to provide banking services to the general public and to small and medium-sized enterprises. Pursuant to the Repeal Act of the Citizens National Bank Act, effective January 5, 1995, the Bank’s status changed to a financial institution which operates under the Banking Act and Commercial Act.

The Bank merged with Korea Long Term Credit Bank on December 31, 1998, and with its subsidiaries, Daegu, Busan, Jeonnam Kookmin Mutual Savings & Finance Co., Ltd., on August 22, 1999. Pursuant to the directive from the Financial Services Commission related to the 1998 Structural Improvement of the Financial Industry Act, the Bank acquired certain assets, including performing loans, and assumed most of the liabilities of Daedong Bank on June 29, 1998. Also, the Bank completed the merger with Housing and Commercial Bank (“H&CB”) on October 31, 2001, and merged with Kookmin Credit Card Co., Ltd., a majority-owned subsidiary, on September 30, 2003. Meanwhile, the Bank spun off its credit card business segment on February 28, 2011, and KB Kookmin Card Co., Ltd. became a subsidiary of KB Financial Group Inc.

The Bank listed its shares on the Stock Market Division of the Korea Exchange (“KRX”) in September 1994. As a result of the merger with H&CB, the shareholders of the former Kookmin Bank and H&CB received new common shares of the Bank which were relisted on the KRX on November 9, 2001. In addition, H&CB listed its American Depositary Shares (“ADS”) on the New York Stock Exchange (“NYSE”) on October 3, 2000, prior to the merger. Following the merger with H&CB, the Bank listed its ADS on the NYSE on November 1, 2001. The Bank became a wholly owned subsidiary of KB Financial Group Inc. through a comprehensive stock transfer on September 29, 2008. Subsequently, the Bank’s shares and its ADS, each listed on the KRX and the NYSE, were delisted on October 10, 2008 and September 26, 2008, respectively. As of December 31, 2025, the Bank’s paid-in capital is ~~W~~ 2,021,896 million.

The Bank engages in the banking business in accordance with the Banking Act, trust business in accordance with the Financial Investment Services and Capital Markets Act, mobile virtual network business in accordance with Special Act on Support for Financial Innovation, and other relevant businesses. As of December 31, 2025, the Bank operates its Seoul headquarters and 771 domestic branches, and 11 overseas branches (excluding five subsidiaries).

2. Basis of Preparation

2.1 Application of Korean IFRS

The Bank and its subsidiaries (collectively the “Group”) maintains its accounting records in Korean won and prepares statutory consolidated financial statements in the Korean language in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”). The accompanying consolidated financial statements have been translated into English from the Korean language consolidated financial statements.

The consolidated financial statements of the Group have been prepared in accordance with Korean IFRS. Korean IFRS are the standards and related interpretations issued by the International Accounting Standards Board (“IASB”) that have been adopted by the Republic of Korea.

The preparation of the consolidated financial statements requires the use of certain critical accounting estimates. Management also needs to exercise judgment in applying the Group’s accounting policies. The areas that require a more complex and higher level of judgment or areas that require significant assumptions and estimations are disclosed in Note 2.4.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

- Korean IFRS No.1118 Presentation and Disclosures in Financial Statements

Korean IFRS No.1118 replaces Korean IFRS No.1001, carrying forward many of the requirements in Korean IFRS No.1001 unchanged and complementing them with new requirements. In addition, some paragraphs from Korean IFRS No.1001 have been moved to Korean IFRS No.1008 and Korean IFRS No.1107. Furthermore, minor amendments have been made to Korean IFRS No.1007 and Korean IFRS No.1033 Earnings per Share.

Korean IFRS No.1118 introduces new requirements to:

•	Present specified categories and defined subtotals in the statement of profit or loss
•	Provide disclosures on management-defined performance measures (MPMs) in the notes to the financial statements<br>
---	---
•	Improve aggregation and disaggregation.
---	---

The Group is required to apply Korean IFRS No.1118 for annual reporting periods beginning on or after January 1, 2027, with earlier application permitted. The amendments to Korean IFRS No.1007 and Korean IFRS No.1033, as well as the revised Korean IFRS No.1008 and Korean IFRS No.1107, become effective when the Group applies Korean IFRS No.1118. Korean IFRS No.1118 requires retrospective application with specific transition provisions. The Group is reviewing the impact of these amendments on the financial statements.

2.2 MeasurementBasis

The consolidated financial statements have been prepared based on the historical cost accounting model unless otherwise specified.

2.3 Functional and Presentation Currency

Items included in the financial statements of each entity of the Group are measured using the currency of the primary economic environment in which the entity operates (“functional currency”). The consolidated financial statements are presented in Korean won, which is the reporting entity’s functional and presentation currency.

2.4 Critical Accounting Estimates

The Group applies accounting policies and uses judgments, accounting estimates, and assumptions that may have a significant impact on the assets (liabilities) and incomes (expenses) in preparing the consolidated financial statements. Management’s estimates of outcomes may differ from actual outcomes if management’s estimates and assumptions based on management’s best judgment are different from the actual environment.

Estimates and underlying assumptions are continually evaluated, and changes in accounting estimates are recognized in the period in which the estimates are changed and in any future periods affected.

Uncertainties in estimates and assumptions with significant risks that may result in material adjustments to the consolidated financial statements are as follows:

2.4.1 Income taxes

As the income taxes on the Group’s taxable income is calculated by applying the tax laws of various countries and the decisions of tax authorities, there is uncertainty in calculating the final tax effect.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

2.4.2 Fair value of financial instruments

The fair value of financial instruments where no active market exists or where quoted prices are not otherwise available is determined by using valuation techniques. Financial instruments, which are not actively traded in the market and those with less transparent market prices, will have less objective fair values and require broad judgment on liquidity, concentration, uncertainty in market factors, assumptions in fair value determination, and other risks.

As described in the significant accounting policies in Note 3.3 Recognition and Measurement of Financial Instruments, diverse valuation techniques are used to determine the fair value of financial instruments, from generally accepted market valuation models to internally developed valuation models that incorporate various types of assumptions and variables.

2.4.3 Allowances and provisions for credit losses

The Group recognizes and measures allowances for credit losses of debt instruments measured at amortized cost and debt instruments measured at fair value through other comprehensive income. Also, the Group recognizes and measures provisions for credit losses of acceptances and guarantees, and unused loan commitments. Accuracy of allowances and provisions for credit losses is dependent upon estimation of expected cash flows of the borrower subject to individual assessment of impairment, and upon assumptions and variables of model used in collective assessment of impairment and estimation of provisions for credit losses of acceptances and guarantees, and unused loan commitments.

Allowances and provisions for credit losses (Allowances, acceptances and guarantees, and unused commitments)

Economic uncertainty persists due to government regulations affecting the real estate market and the downturn in the construction sector driven by oversupply, while prolonged high interest rates increase repayment burdens and may lead to a deterioration in asset quality. Accordingly, the Group has reflected the potential impact on expected credit losses though a management overlay, based on a comprehensive review of vulnerable sectors in the event that COVID-19 related support measures expire. In addition, the Group estimates relevant risk parameters based on a holistic review and incorporates forward-looking economic information into those parameters. The Group will continue to monitor the impact of economic uncertainty and government policies on expected credit losses. Further details of the impact on expected credit losses are presented in Note 11.1 Changes in allowances for credit losses of loans measured at amortized cost and Note 22.2 Changes in provisions for credit losses of unused loan commitments, and acceptances and guarantees.

2.4.4 Net defined benefit asset (liability)

The present value of the net defined benefit asset(liability) is affected by changes in the various factors determined by the actuarial method.

2.4.5 Impairment of goodwill

The recoverable amounts of cash-generating units are determined based on value-in-use calculations to test whether impairment of goodwill has occurred.

3. Material Accounting Policies

The principal accounting policies applied in the preparation of these consolidated financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

3.1 Consolidation

3.1.1 Subsidiaries

Subsidiaries are companies that are controlled by the Group. The Group 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. Also, the existence and effects of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Group controls the investee. Subsidiaries are fully consolidated from the date when control is transferred to the Group and de-consolidated from the date when control is lost.

If a subsidiary uses accounting policies other than those adopted in the consolidated financial statements for like transactions and events in similar circumstances, appropriate adjustments are made to that subsidiary’s financial statements in preparing the consolidated financial statements to ensure conformity with the Group’s accounting policies.

Profit or loss and each component of other comprehensive income are attributed to the owners of the parent and to the non-controlling interests, if any. Total comprehensive income is attributed to the owners of the parent and to the non-controlling interests even if this results in the non-controlling interests having a deficit balance.

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions (i.e., transactions with owners in their capacity as owners). The difference between fair value of any consideration paid and carrying amount of the subsidiary’s net assets attributable to the additional interests acquired, is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

When the Group loses control, any investment retained in the former subsidiary is recognized at its fair value at the date when control is lost, with the resulting difference recognized in profit or loss. This fair value will be the fair value on initial recognition of a financial asset in accordance with Korean IFRS No.1109 or, when appropriate, the cost on initial recognition of an investment in an associate or joint venture. In addition, all amounts previously recognized in other comprehensive income in relation to that subsidiary are accounted for on the same basis as would be required if the Group had directly disposed of the related assets or liabilities. Therefore, amounts previously recognized in other comprehensive income are reclassified to profit or loss.

The Group accounts for each business combination by applying the acquisition method. The consideration transferred is measured at fair value, and identifiable assets acquired, and liabilities and contingent liabilities assumed in a business combination are initially measured at acquisition-date fair values. For each business combination, the Group measures non-controlling interests in the acquiree that entitle their holders to a proportionate share of the acquiree’s net assets in the event of liquidation at either (a) fair value or (b) the proportionate share in the recognized amounts of the acquiree’s identifiable net assets. Acquisition-related costs are expensed in the periods in which the costs are incurred.

In a business combination achieved in stages, the Group shall remeasure its previously held equity interest in the acquiree at its acquisition-date fair value and recognize the resulting gain or loss, if any, in profit or loss or other comprehensive income, as appropriate. In prior reporting periods, the Group may have recognized changes in the value of its equity interest in the acquiree in other comprehensive income. If so, the amount that was recognized in other comprehensive income shall be reclassified as profit or loss, or retained earnings, on the same basis as would be required if the Group had directly disposed of the previously held equity interest.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

The Group applies the book-value method to account for business combinations of entities under common control. Identifiable assets acquired and liabilities assumed in a business combination are measured at their book value on the consolidated financial statements of the Group. In addition, the difference between (a) the sum of consolidated net book value of the assets and liabilities transferred and accumulated other comprehensive income and (b) the consideration paid, is recognized as capital surplus.

3.1.2 Associates

Associates are entities over which the Group has significant influence over the financial and operating policy decisions. Generally, if the Group holds 20% or more of the voting power of the investee, it is presumed that the Group has significant influence.

Investments in associates are initially recognized at cost and equity method is applied after initial recognition. The carrying amount is increased or decreased to recognize the Group’s share of the profit or loss of the investee and changes in the investee’s equity after the date of acquisition. Distributions received from an investee reduce the carrying amount of the investment. Unrealized gains and losses resulting from transactions between the Group and associates are eliminated to the extent of the Group’s share in associates. If unrealized losses are an indication of an impairment that requires recognition in the consolidated financial statements, those losses are recognized for the period.

If associates use accounting policies other than those of the Group for like transactions and events in similar circumstances, if necessary, adjustments shall be made to make the associates’ accounting policies conform to those of the Group when the associates’ financial statements are used by the Group in applying the equity method.

If the Group’s share of losses of associates equals or exceeds its interest in the associates (including long-term interests that, in substance, form part of the Group’s net investment in the associates), the Group discontinues recognizing its share of further losses. After the Group’s interest is reduced to zero, additional losses are provided for, and a liability is recognized, only to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of the associates.

The Group determines at each reporting period whether there is any objective evidence that the investments in the associates are impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associates and its carrying amount and recognizes the amount as non-operating expenses in the consolidated statement of comprehensive income.

3.1.3 Structured entity

A structured entity is an entity that has been designed so that voting or similar rights are not the dominant factor in deciding who controls the entity. When the Group decides whether it has power over the structured entities in which the Group has interests, it considers factors such as the purpose, the form, the substantive ability to direct the relevant activities of a structured entity, the nature of its relationship with a structured entity, and the amount of exposure to variable returns.

3.1.4 Funds management

The Group manages and operates trust assets, collective investment, and other funds on behalf of investors. These trusts and funds are not consolidated, except for trusts and funds over which the Group has control.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.1.5 Intragroup transactions

Intragroup balances, income, expenses, and any unrealized gains and losses resulting from intragroup transactions are eliminated in full, in preparing the consolidated financial statements. If unrealized losses are an indication of an impairment that requires recognition in the consolidated financial statements, those losses are recognized for the period.

3.2 Foreign Currency

3.2.1 Foreign currency transactions

A foreign currency transaction is recorded, at initial recognition in the functional currency, by applying to the foreign currency amount the spot exchange rate between the functional currency and the foreign currency at the date of the transaction. At the end of each reporting period, foreign currency monetary items are translated using the closing rate which is the spot exchange rate at the end of the reporting period. Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rate at the date when the fair value was measured and non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rate at the date of the transaction.

Except for the exchange differences for the net investment in a foreign operation and the financial liability designated as a hedging instrument of net investment, exchange differences arising on the settlement of monetary items or on translating monetary items are recognized in profit or loss. When a gain or loss on a non-monetary item is recognized in other comprehensive income, any exchange component of that gain or loss is recognized in other comprehensive income. Conversely, when a gain or loss on a non-monetary item is recognized in profit or loss, any exchange component of that gain or loss is recognized in profit or loss.

3.2.2 Foreign operations

The results and financial position of a foreign operation, whose functional currency differs from the Group’s presentation currency, are translated into the Group’s presentation currency based on the following procedures.

If the functional currency of a foreign operation is not the currency of a hyperinflationary economy, assets and liabilities for each statement of financial position presented (including comparatives) are translated at the closing rate at the end of the reporting period, income and expenses for each statement of comprehensive income presented (including comparatives) are translated using the average exchange rates for the period. All resulting exchange differences are recognized in other comprehensive income.

Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of that foreign operation are treated as assets and liabilities of the foreign operation. Thus, they are expressed in the functional currency of the foreign operation and are translated into the presentation currency at the closing rate.

On the disposal of a foreign operation, the cumulative amount of the exchange differences relating to that foreign operation, recognized in other comprehensive income and accumulated in the separate component of equity, is reclassified from equity to profit or loss (as a reclassification adjustment) when the gain or loss on disposal is recognized. On the partial disposal of a subsidiary that includes a foreign operation, the Group re-attributes the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income to the non-controlling interests in that foreign operation. In any other partial disposal of a foreign operation, the Group reclassifies to profit or loss only the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.2.3 Translation of the net investment in a foreign operation

A monetary item that is receivable from or payable to a foreign operation, for which settlement is neither planned nor likely to occur in the foreseeable future is, in substance, a part of the Group’s net investment in that foreign operation. The foreign currency difference arising from that monetary item is recognized in other comprehensive income and shall be reclassified to profit or loss on disposal of the net investment.

3.3 Recognition and Measurement of Financial Instruments

3.3.1 Initial recognition

The Group recognizes a financial asset or a financial liability in its consolidated statement of financial position when the Group becomes party to the contractual provisions of the instrument. A regular way purchase or sale of financial assets (a purchase or sale of a financial asset under a contract whose terms require delivery of the asset within the time frame established generally by regulation or convention in the marketplace concerned) is recognized and derecognized using trade date accounting.

For financial reporting purpose, the Group classifies (a) financial assets as financial assets at fair value through profit or loss, financial assets at fair value through other comprehensive income, or financial assets at amortized cost and (b) financial liabilities as financial liabilities at fair value through profit or loss, or other financial liabilities. These classifications are based on the business model for managing financial instruments and the contractual cash flow characteristics of the financial instrument at initial recognition.

At initial recognition, a financial asset or financial liability is measured at its fair value plus or minus, in the case of a financial asset or financial liability not at fair value through profit or loss, transaction costs that are directly attributable to the acquisition or issue of the financial asset or financial liability. The 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. The fair value of a financial instrument on initial recognition is normally the transaction price (that is, the fair value of the consideration given or received) in an arm’s length transaction.

3.3.2 Subsequent measurement

After initial recognition, financial instruments are measured at amortized cost or fair value based on classification at initial recognition.

3.3.2.1 Amortized cost

The amortized cost of a financial asset or financial liability is the amount at which the financial asset or financial liability is measured at initial recognition minus the principal repayments, plus or minus the cumulative amortization using the effective interest method of any difference between that initial amount and the maturity amount and, for financial assets, adjusted for any loss allowance.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.3.2.2 Fair value

The Group uses quoted price in an active market which is based on listed market price or dealer price quotations of financial instruments traded in an active market as best estimate of fair value. A financial instrument is regarded as quoted in an active market if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis.

If there is no active market for a financial instrument, fair value is determined either by using a valuation technique or independent third-party valuation service. Valuation techniques include using recent arm’s length market transactions between knowledgeable and willing parties, if available, referencing the current fair value of another instrument that is substantially the same, discounted cash flow analysis, and option pricing models.

The Group uses valuation models that are commonly used by market participants and customized for the Group to determine fair values of common over-the-counter (“OTC”) derivatives such as options, interest rate swaps, and currency swaps which are based on the inputs observable in markets. However, for some complex financial instruments that require fair value measurement by valuation techniques based on certain assumptions because some or all inputs used in the model are not observable in the market, the Group uses internal valuation models developed from general valuation models or valuation results from independent external valuation institutions.

In addition, the fair value information recognized in the consolidated statement of financial position is classified into the following fair value hierarchy, reflecting the significance of the input variables used in the fair value measurement.

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Group can access at the measurement date

Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly

Level 3: Unobservable inputs for the asset or liability

The fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. For this purpose, the significance of an input is assessed against the fair value measurement in its entirety.

If a fair value measurement uses observable inputs that require significant adjustment using unobservable inputs, that measurement is a Level 3 measurement.

The Group’s Fair Value Evaluation Committee, which consists of the risk management department, trading department and accounting department, reviews the appropriateness of internally developed valuation models, and approves the selection and changing of the external valuation institution and other considerations related to fair value measurement. The results of regular verification of the internally developed valuation models are reported to the Market Risk Management Subcommittee.

If the valuation technique does not reflect all factors which market participants would consider in pricing the asset or liability, the fair value is adjusted to reflect those factors. Those factors include counterparty credit risk, liquidity risk, and others.

The Group uses a valuation technique which maximizes the use of market inputs and minimizes the use of entity-specific inputs. It incorporates all factors that market participants would consider in pricing the asset or liability and is consistent with economic methodologies applied for pricing financial instruments. Periodically, the Group calibrates the valuation technique and tests its validity using prices of observable current market transactions of the same instrument or based on other relevant observable market data.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.3.3 Derecognition

Derecognition is the removal of a previously recognized financial asset or financial liability from the consolidated statement of financial position. The derecognition criteria for financial assets and financial liabilities are as follows:

3.3.3.1 Derecognition of financial assets

A financial asset is derecognized when the contractual rights to the cash flows from the financial assets expire or the Group transfers substantially all the risks and rewards of ownership of the financial asset, or the Group neither transfers nor retains substantially all the risks and rewards of ownership of the financial asset and the Group has not retained control. Therefore, if the Group does not transfer substantially all the risks and rewards of ownership of the financial asset, the Group continues to recognize the financial asset to the extent of its continuing involvement in the financial asset.

If the Group transfers the contractual rights to receive the cash flows of the financial asset but retains substantially all the risks and rewards of ownership of the financial asset, the Group continues to recognize the transferred asset in its entirety and recognize a financial liability for the consideration received.

The Group writes off a financial asset when the Group has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. In general, the Group considers write-off when it is determined that the debtor does not have sufficient funds or income to cover the principal and interest. The write-off decision is made in accordance with internal policy. After the write-off, the Group can continue to collect the written-off loans according to the internal policy. Recovered amounts from financial assets previously written-off are recognized in profit or loss.

3.3.3.2 Derecognition of financial liabilities

A financial liability is derecognized from the consolidated statement of financial position when it is extinguished (i.e., the obligation specified in the contract is discharged, canceled or expires).

3.3.4 Offsetting

A financial asset and a financial liability are offset, and the net amount is presented in the consolidated statement of financial position when, and only when, the Group currently has a legally enforceable right to offset the recognized amounts and intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on a future event and must be legally enforceable in the normal course of business, the event of default, and the event of insolvency or bankruptcy of the Group and all of the counterparties.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.4 Cash and Due from Financial Institutions

Cash and due from financial institutions include cash on hand, foreign currency, and short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, and due from financial institutions. Cash and due from financial institutions are measured at amortized cost.

3.5 Non-derivative Financial Assets

3.5.1 Financial assets at fair value through profit or loss

Financial assets are classified as financial assets at fair value through profit or loss unless they are classified as financial assets at amortized cost or at fair value through other comprehensive income.

The Group may designate certain financial assets upon initial recognition as at fair value through profit or loss when the designation eliminates or significantly reduces a measurement or recognition inconsistency (sometimes referred to as an ‘accounting mismatch’) that would otherwise arise from measuring assets or liabilities or recognizing the gains and losses on them on different bases.

After initial recognition, a financial asset at fair value through profit or loss is measured at fair value and gains or losses arising from a change in fair value are recognized in profit or loss. Interest income using the effective interest method and dividend income from financial assets at fair value through profit or loss are also recognized in profit or loss.

3.5.2 Financial assets at fair value through other comprehensive income

The Group classifies below financial assets as financial assets at fair value through other comprehensive income:

Equity instruments that are not held for short-term trading but held for strategic investment, and designated as financial assets at fair value through other comprehensive income

After initial recognition, a financial asset at fair value through other comprehensive income is measured at fair value. Gains or losses arising from a change in fair value, other than dividend income, interest income calculated using the effective interest method and exchange differences arising on monetary items which are recognized directly in profit or loss, are recognized in other comprehensive income in equity.

When the financial assets at fair value through other comprehensive income is disposed of, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. However, cumulative gain or loss of equity instruments designated at fair value through other comprehensive income is reclassified to retained earnings not to profit or loss at disposal.

A financial asset at fair value through other comprehensive income denominated in foreign currency is translated at the closing rate. Exchange differences resulting from changes in amortized cost are recognized in profit or loss, and other changes are recognized in equity.

December 31, 2025 and 2024

3.5.3 Financial assets at amortized cost

A financial asset, which is held within the business model whose objective is achieved by collecting contractual cash flows, and where the assets’ cash flows represent solely payments of principal and interest on the principal amount outstanding, is classified as a financial asset at amortized cost. After initial recognition, a financial asset at amortized cost is measured at amortized cost using the effective interest method and interest income is calculated using the effective interest method.

3.6 Expected Credit Losses of Financial Assets(Debt Instruments)

The Group recognizes loss allowances for expected credit losses at the end of the reporting period for financial assets at amortized cost and fair value through other comprehensive income except for financial assets at fair value through profit or loss.

Expected credit losses are estimated at present value of probability-weighted amount that is determined by evaluating a range of possible outcomes. The Group measures expected credit losses by reflecting all 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 approaches of measuring expected credit losses in accordance with Korean IFRS are as follows:

•	General approach: for financial assets and unused loan commitments not subject to the below approach<br>
•	Credit-impaired approach: for financial assets that are credit-impaired at the time of acquisition<br>
---	---

Application of general approach is differentiated depending on whether credit risk has increased significantly after initial recognition. If the credit risk on a financial instrument has not increased significantly since initial recognition, the Group measures loss allowances for that financial instrument at an amount equal to 12-month expected credit losses, whereas if the credit risk on a financial instrument has increased significantly since initial recognition, the Group measures loss allowances for a financial instrument at an amount equal to the lifetime expected credit losses. Lifetime is the period until the contractual maturity date of financial instruments and means the expected life.

The Group assesses whether the credit risk has increased significantly using the following criteria, and if one or more of the following criteria are met, it is deemed as significant increase in credit risk. Criterion of more than 30 days past due is applied to all subsidiaries, and other criteria are applied selectively considering specific indicators of each subsidiary or additionally considering specific indicators of each subsidiary. If the contractual cash flows of a financial asset have been renegotiated or modified, the Group assesses whether the credit risk has increased significantly using the same following criteria.

•	More than 30 days past due
•	Decline in credit rating at the end of the reporting period by certain notches or more compared to the time of<br>initial recognition
---	---
•	Subsequent managing ratings below certain level in the early warning system
---	---
•	Debt restructuring (except for impaired financial assets)

•	Identification of a significant increase in other credit risk, etc.

3.6.1 Forward-looking information

The Group uses forward-looking information, when determining whether credit risk has increased significantly and measuring expected credit losses.

The Group assumes that the risk components have a constant correlation with the economic cycle and uses statistical methodologies to estimate the relation between key macroeconomic variables and risk components for the expected credit losses. The Group has derived a correlation between the time series data of 15 years or more and the key macroeconomic variables and calculates the expected credit losses by reflecting the results of the correlation on the risk component.

The correlation between the major macroeconomic variables and the credit risk are as follows:

Key macroeconomic variables		Correlation between the major macroeconomicvariables andthe credit risk
Benchmark interest rate		(+)
AA- rated corporate bond (3-year)		(+)
BBB- rated corporate bond (3-year)		(+)
Composite stock index		(-)
Rate of increase in housing transaction price index (Whole Country)		(-)
Rate of increase in housing transaction price index (Metropolitan Area)		(-)
WTI crude oil price		(+)

Forward-looking information used in the calculation of expected credit losses is based on the macroeconomic forecasts utilized by management of the Group for its business plan considering reliable external agency’s forecasts and others. The forward-looking information is generated by KB Research with a comprehensive approach to capture the possibility of various economic forecast scenarios that are derived from the internal and external viewpoints of the macroeconomic situation. The Group determines the macroeconomic variables to be used in forecasting future conditions of the economy, considering the direction of the forecast scenario based on GDP growth and the significant relationship between macroeconomic variables and time series data. Some macroeconomic variables used are different than those used in the previous year.

As of December 31, 2025, the Group measures expected credit losses by applying both the worse scenario and the crisis scenario, taking into consideration the potential credit risk resulting from the uncertain financial environment locally and globally and the rapid economic recession.

3.6.2 Measuring expected credit losses on financial assets at amortized cost

The expected credit losses of financial assets at amortized cost are measured as present value of the difference between the contractual cash flows to be received and the cash flows expected to be received. The Group estimates expected future cash flows for financial assets that are individually significant. The Group selects the individually significant financial assets by comprehensively considering quantitative and qualitative factors (such as debt restructuring or negative net assets, etc.) when the credit risk has increased significantly or the financial asset in credit-impaired (individual assessment of impairment).

For financial assets that are not individually significant, the Group collectively estimates expected credit losses by grouping loans with a homogeneous credit risk profile (collective assessment of impairment).

3.6.2.1 Individual assessment of impairment

Individual assessment of impairment losses is performed using management’s best estimate on the present value of expected future cash flows. The Group uses all the available information including financial condition of the borrower such as operating cash flow and net realizable value of any collateral held.

3.6.2.2 Collective assessment of impairment

Collective assessment of impairment losses is performed by using a methodology based on historical loss experience and reflecting forward-looking information. Such a process incorporates factors such as type of collateral, type of product, type of borrower, credit rating, size of portfolio, and recovery period and applies Probability of Default (“PD”) on a group of assets and Loss Given Default (“LGD”) by type of recovery method. Also, the Group applies certain assumptions to model expected credit losses assessment and to determine input based on loss experience and forward-looking information. These models and assumptions are periodically reviewed to reduce the gap between loss estimate and actual loss experience.

The lifetime expected credit losses are measured by applying the PD to the carrying amount, which is calculated by deducting the expected principal repayment amount from the carrying amount as of the reporting date, and the LGD adjusted to reflect changes in the carrying amount.

3.6.3 Measuring expected credit losses on financial assets at fair value through other comprehensive income

The Group measures expected credit losses on financial assets at fair value through other comprehensive income in a manner that is consistent with the requirements that are applicable to financial assets at amortized cost. However, loss allowances are recognized in other comprehensive income. Upon disposal or repayment of financial assets at fair value through other comprehensive income, the amount of loss allowances is reclassified from other comprehensive income to profit or loss.

3.7 Derivative Financial Instruments

The Group enters into numerous derivative financial instrument contracts such as currency forwards, interest rate swaps, currency swaps, and others for trading purposes or to manage its interest rate risk, currency risk, and others. The Group’s derivative financial instruments business focuses on addressing the needs of the Group’s corporate clients to hedge their risk exposure and to hedge the Group’s risk exposure that results from such client contracts. These derivative financial instruments are presented as derivative financial instruments in the consolidated financial statements irrespective of transaction purpose and subsequent measurement requirement.

The Group designates certain derivative financial instruments as hedging instruments to hedge the risk of changes in fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge) and the risk of changes in cash flow (cash flow hedge). The Group designates certain derivative and non-derivative financial instruments as hedging instruments to hedge the currency risk of the net investment in a foreign operation (hedge of net investment).

At the inception of the hedging relationship, there is formal designation and documentation of the hedging relationship and the Group’s risk management objective and strategy for undertaking the hedge. This documentation includes identification of the hedging instrument, the hedged item, the nature of the risk being hedged, the inception date of hedging relationship and how the Group will assess the hedging instrument’s effectiveness in offsetting the changes in the hedged item’s fair value or cash flows attributable to the hedged risk.

Derivative financial instruments are initially recognized at fair value. After initial recognition, derivative financial instruments are measured at fair value, and changes therein are accounted for as described below.

3.7.1 Derivative financial instruments held for trading

All derivative financial instruments, except for derivatives that are designated and qualify for hedge accounting, are measured at fair value. Gains or losses arising from changes in fair value are recognized in profit or loss as part of net gains or losses on financial instruments at fair value through profit or loss.

3.7.2 Derivative financial instruments for fair value hedges

If derivative financial instruments are designated and qualify for fair value hedges, changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk are recognized in profit or loss as part of other operating income or expenses. If the hedged items are equity instruments for which the Group has elected to present changes in fair value in other comprehensive income, changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk are recognized in other comprehensive income.

Fair value hedge accounting is discontinued prospectively if the hedging instrument expires or is sold, terminated or exercised, or the hedging relationship ceases to meet the qualifying criteria. Once fair value hedge accounting is discontinued, the adjustment to the carrying amount of a hedged item is amortized to profit or loss by the maturity of the financial instrument using the effective interest method.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.7.3 Derivative financial instruments for cash flow hedges

The effective portion of changes in fair value of derivative financial instruments that are designated and qualify for cash flow hedges is recognized in other comprehensive income, limited to the cumulative change in fair value (present value) of the hedged item (the present value of the cumulative change in the hedged expected future cash flows) from inception of the hedge. The ineffective portion is recognized in profit or loss as other operating income or expenses. The associated gains or losses that were previously recognized in other comprehensive income are reclassified from equity to profit or loss (other operating income or expenses) as a reclassification adjustment in the same period or periods during which the hedged forecast cash flows affect profit or loss. Cash flow hedge accounting is discontinued prospectively if the Group’s risk management strategy or objective changes, or if the hedging instrument expires, is sold, terminated or exercised, or the hedging relationship ceases to meet the qualifying criteria. When the cash flow hedge accounting is discontinued, the cumulative gains or losses on the hedging instrument that have been recognized in other comprehensive income are reclassified to profit or loss over the period in which the forecast transaction occurs. If the forecast transaction is no longer expected to occur, the cumulative gains or losses that have been recognized in other comprehensive income are immediately reclassified to profit or loss.

3.7.4 Derivative and non-derivative financial instruments designated for net investments hedges

If derivative and non-derivative financial instruments are designated and qualify for the net investment hedge, the effective portion of changes in fair value of the hedging instrument is recognized in other comprehensive income and the ineffective portion is recognized in profit or loss as other operating income or expenses. The cumulative gains or losses on the hedging instrument relating to the effective portion of the hedge that have been accumulated in other comprehensive income will be reclassified from other comprehensive income to profit or loss as a reclassification adjustment on the disposal or partial disposal of the foreign operation.

3.7.5 Risk management strategy

Interest rate risk arises from changes in fair value resulting from changes in the discount rate of fixed rate financial instruments and changes in cash flows resulting from changes in the nominal interest rate of floating rate financial instruments. Foreign currency risk arises from the net investment in a foreign operation, whose functional currency differs from the Group’s functional currency.

While the Group hedges the interest rate risk in its entirety, the Group only hedges the foreign currency risk related to the proportional part of the notional amount.

At inception of the hedge relationship, the Group reviews the hedge effectiveness; and periodically reviews the effectiveness in order to confirm that economic relationship between the hedged item and the hedging instrument exists. The requirement that an economic relationship exists means that the hedging instrument and the hedged item have values that generally move in the opposite direction due to the same risk, which is the hedged risk. The Group designates the exposure of the hedged item opposite to the exposure of hedging instruments in order to meet economic relationship requirement.

The Group designates the hedge relationship at a one-on-one ratio between the nominal amount of the hedging instrument and the nominal amount of the hedged item.

Hedge ineffectiveness could arise because of differences in the underlying parameters (acquisition date, credit risk or liquidity and others) or other differences between the hedging instrument and the hedged item that the Group accepts in order to achieve a cost-effective hedging relationship.

The Group avoids the cash flow variability of its floating rate debt securities by using interest rate swaps. Both are linked to the same interest rate; however, the paid amount of the floating rate may be set on different dates. Even if the variability of interest rate related cash flows (as a risk factor) is designated as a hedged item, the difference in set-up dates creates a hedge ineffectiveness.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

The Group avoids the variability of fair values of its fixed rate debt securities by using interest rate swaps. The method of calculating the number of dates for paying fixed-rate interest can be different between hedging instruments and hedged items. Even if the variability of the fair value due to the benchmark interest rate (as a risk factor) is designated as a hedged item, the difference in the method of calculating the number of the dates creates a hedge ineffectiveness.

3.7.6 Embedded derivatives

An embedded derivative is separated from the host contract and accounted for as a derivative if, and only if, (a) the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract, (b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative and (c) the hybrid contract contains a host that is not a financial asset and is not designated as at fair value through profit or loss. Gains or losses arising from a change in fair value of an embedded derivative separated from the host contract are recognized in profit or loss as part of net gains or losses on financial instruments at fair value through profit or loss.

3.7.7 Day one gains or losses

If the Group uses a valuation technique that incorporates unobservable inputs for the fair value of the OTC derivatives at initial recognition, there may be a difference between the transaction price and the amount determined using that valuation technique. In these circumstances, the difference is not recognized in profit or loss but deferred and amortized using the straight-line method over the life of the financial instrument. If the fair value is subsequently determined using observable inputs, the remaining deferred amount is recognized in profit or loss as part of net gains or losses on financial instruments at fair value through profit or loss or other operating income or expenses.

3.8 Property and Equipment

3.8.1 Recognition and measurement

Property and equipment that qualify for recognition as an asset are measured at cost and subsequently carried at its cost less any accumulated depreciation and any accumulated impairment losses.

The cost of property and equipment includes any costs directly attributable to bringing the asset to the location and the asset’s condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located.

Subsequent expenditures are capitalized only when they prolong the useful life or enhance values of the assets, but the costs of the day-to-day servicing of the assets such as repair and maintenance costs are recognized in profit or loss as incurred. When part of an item of property and equipment has a useful life different from that of the entire asset, it is recognized as a separate asset.

3.8.2 Depreciation

Land is not depreciated, whereas other property and equipment are depreciated using the method that reflects the pattern in which the asset’s future economic benefits are expected to be consumed by the Group. The depreciable amount of an asset is determined after deducting its residual value.

Each part of an item of property and equipment with a cost that is significant in relation to the total cost of the item is depreciated separately.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

The depreciation method and estimated useful life of property and equipment are as follows:

Property and equipment	Depreciation method	Estimated useful life
Buildings	Straight-line	20 ~ 40 years
Leasehold improvements	Diminishing-balance	4 years
Equipment and vehicles	Diminishing-balance	4 years

The residual value, the useful life, and the depreciation method applied to an asset are reviewed at each financial year-end and, if expectations differ from previous estimates, the changes are accounted for as a change in an accounting estimate.

3.9 Investment Properties

3.9.1 Recognition and measurement

Properties held to earn rentals or for capital appreciation or both are classified as investment properties. Investment properties are measured initially at their cost and subsequently the cost model is used.

3.9.2 Depreciation

Land is not depreciated, whereas other investment properties are depreciated using the method that reflects the pattern in which the asset’s future economic benefits are expected to be consumed by the Group. The depreciable amount of an asset is determined after deducting its residual value.

The depreciation method and estimated useful life of investment properties are as follows:

Investment properties		Depreciation method		Estimated useful life
Buildings		Straight-line		40 years

3.10 Intangible Assets

Intangible assets are measured initially at cost and subsequently carried at their cost less any accumulated amortization and any accumulated impairment losses.

Intangible assets, except for goodwill and membership rights, are amortized using the straight-line or declining-balance method with no residual value over their estimated useful life since the assets are available for use.

Intangible assets	Amortization method	Estimated useful life
Industrial property rights	Straight-line	5 years
Software	Straight-line	4 ~ 5 years
Others	Straight-line / Declining-balance	1 ~ 13 years

The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at each financial year-end. Where an intangible asset is not being amortized because its useful life is indefinite, the Group carries out a review in each accounting period to confirm whether events and circumstances still support an indefinite useful life assessment. If they do not, the change in the useful life assessment from indefinite to finite is accounted for as a change in an accounting estimate.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.10.1 Goodwill

3.10.1.1 Recognition and measurement

Goodwill related to business combinations before January 1, 2010, is stated at its carrying amount, which was recognized under the Group’s previous accounting policy, prior to the transition to Korean IFRS.

Goodwill acquired from business combinations after January 1, 2010, is initially measured as the excess of the consideration transferred over the fair value of net identifiable assets acquired and liabilities assumed. If the fair value of net identifiable assets acquired and liabilities assumed exceeds the consideration transferred, the difference is recognized in profit or loss.

For each business combination, the Group decides at the acquisition date whether the non-controlling interests in the acquiree are initially measured at fair value or at the non-controlling interests’ proportionate share in the recognized amounts of the acquiree’s identifiable net assets.

Acquisition-related costs incurred to effect a business combination are charged to expenses in the periods in which the costs are incurred and the services are received, except for the costs to issue debt or equity securities.

3.10.1.2 Additional acquisitions of non-controlling interests

Additional acquisitions of non-controlling interests are accounted for as equity transactions. Therefore, no additional goodwill is recognized.

3.10.1.3 Subsequent measurement

Goodwill is not amortized and is stated at cost less accumulated impairment losses. Goodwill that forms part of the carrying amount of an investment in associates is not separately recognized, and an impairment loss recognized is not allocated to any asset, including goodwill, which forms part of the carrying amount of the investment in the associates.

3.10.2 Subsequent expenditures

Subsequent expenditures are capitalized only when they enhance values of the assets. Internally generated intangible assets, such as goodwill and trade name, are not recognized as assets but expensed as incurred.

3.11 Impairment of Non-financial Assets

The Group assesses at the end of each reporting period whether there is any indication that a non-financial asset, except for (a) deferred income tax assets, (b) assets arising from employee benefits and (c) non-current assets (or group of assets to be sold) classified as held for sale, may be impaired. If any such indication exists, the Group estimates the recoverable amount of the asset. However, irrespective of whether there is any indication of impairment, the Group tests (a) goodwill acquired in a business combination, (b) intangible assets with an indefinite useful life and (c) intangible assets not yet available for use for impairment annually by comparing their carrying amount with their recoverable amount.

The recoverable amount is estimated for the individual asset. If it is not possible to estimate the recoverable amount of the individual asset, the Group determines the recoverable amount of the cash-generating unit to which the asset belongs. A cash-generating unit is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset is the higher of its fair value less costs of disposal and its value in use. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit that are discounted by a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the future cash flow estimates have not been adjusted.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

If the recoverable amount of an asset is less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount. That reduction is an impairment loss and recognized immediately in profit or loss. For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the cash-generating units that is expected to benefit from the synergies of the combination. The impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the cash-generating unit and then to the other assets of the unit pro rata on the basis of the carrying amount of each asset in the unit.

An impairment loss recognized for goodwill is not reversed in a subsequent period. The Group assesses 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, and an impairment loss recognized in prior periods for an asset other than goodwill shall be reversed if, and only if, there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. The increased carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss cannot exceed the carrying amount that would have been determined (net of amortization or depreciation) had no impairment loss been recognized for the asset in prior years.

3.12 Non-current Assets Held for Sale

A non-current asset or disposal group is classified as held for sale if its carrying amount will be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset (or disposal group) must be available for immediate sale in its present condition and its sale must be highly probable. A non-current asset (or disposal group) classified as held for sale is measured at the lower of (a) its carrying amount measured in accordance with the applicable Korean IFRS, immediately before the initial classification of the asset (or disposal group) as held for sale and (b) fair value less costs to sell.

A non-current asset is not depreciated (or amortized) while it is classified as held for sale or is part of a disposal group classified as held for sale.

Impairment loss is recognized for any initial or subsequent write-down of the asset (or disposal group) to fair value less costs to sell. Gain is recognized for any subsequent increase in fair value less costs to sell of an asset, but not in excess of the cumulative impairment loss that has been recognized.

3.13 Financial Liabilities

The Group classifies financial liabilities into financial liabilities at fair value through profit or loss or other financial liabilities in accordance with the substance of the contractual arrangement and the definitions of financial liabilities. The Group recognizes financial liabilities in the consolidated statement of financial position when the Group becomes a party to the contractual provisions of the financial liability.

3.13.1 Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such at initial recognition. After initial recognition, financial liabilities at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. At initial recognition, transaction costs that are directly attributable to the acquisition are recognized in profit or loss as incurred.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

In relation to securities lending or borrowing transactions, when the Group borrows securities from the Korea Securities Depository and others, these transactions are managed as off-balance sheet items. The borrowed securities are treated as financial liabilities at fair value through profit or loss when they are sold. Changes in fair value at the end of the reporting period and difference between carrying amount at redemption and purchased amount are recognized in profit or loss.

3.13.2 Other financial liabilities

Non-derivative financial liabilities other than financial liabilities at fair value through profit or loss are classified as other financial liabilities. Other financial liabilities include deposits, borrowings, debentures, and others. At initial recognition, other financial liabilities are measured at fair value minus transaction costs that are directly attributable to the acquisition. After initial recognition, other financial liabilities are measured at amortized cost, and its interest expense is recognized, using the effective interest method.

When an asset is sold under repurchase agreement, the Group continues to recognize the asset with the amount sold being accounted for as borrowings. The Group derecognizes a financial liability from the consolidated statement of financial position only when it is extinguished (i.e., when the obligation specified in the contract is discharged, canceled or expires).

3.14 Provisions

Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Inevitable risks and uncertainties surrounding related events and circumstances are considered in measuring the best estimate of the provisions, and where the effect of the time value of money is material, the amount of provisions is the present value of the expenditures expected to be required to settle the obligation.

Provisions for confirmed and unconfirmed acceptances and guarantees, and unused credit lines of consumer and corporate loans are recognized using a valuation model that applies the credit conversion factor, PD, and LGD.

Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimate. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provisions are reversed.

An onerous contract is a contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs under a contract reflect the least net cost of exiting from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfill it. If the Group has a contract that is onerous, the present obligation under the contract is recognized and measured as provisions.

3.15 Financial Guarantee Contracts

Financial guarantee contracts require the issuer to make specified payments to reimburse the holder for a loss it incurs because a specified debtor fails to make payments when due in accordance with the original or modified terms of a debt instrument.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

Financial guarantee contracts are initially recognized at fair value, and classified as other liabilities and are amortized over the contractual term. After initial recognition, financial guarantee contracts are measured at the higher of:

•	The amount determined in accordance with Korean IFRS No.1109 Financial Instruments and<br>
•	The amount initially recognized less, when appropriate, the cumulative amount of income recognized in accordance<br>with Korean IFRS No.1115 Revenue from Contracts with Customers.
---	---

3.16 Equity Instrument Issued by the Group

An equity instrument is any contract or agreement that evidences a residual interest in the assets of an entity after deducting all of its liabilities.

3.16.1 Ordinary shares

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or the exercise of stock option are deducted from the equity, net of any tax effects.

3.16.2 Hybrid securities

The financial instruments can be classified as either financial liabilities or equity in accordance with the terms of the contract. The Group classifies hybrid securities as an equity if the Group has the unconditional right to avoid any contractual obligation to deliver cash or another financial asset in relation to the financial instruments. However, hybrid securities issued by subsidiaries are classified as non-controlling interests, dividends are recognized in the consolidated statement of comprehensive income as profit attributable to non-controlling interests.

3.16.3 Compound financial instruments

A compound financial instrument is classified as a financial liability or an equity instrument depending on the substance of the contractual arrangement of such financial instrument. The liability component of the compound financial instrument is measured at fair value of the similar liability without conversion option at initial recognition and subsequently measured at amortized cost using effective interest method until it is extinguished by conversion or matured. The equity component is initially measured at fair value of compound financial instrument in its entirety less fair value of liability component net of tax effect, and it is not remeasured subsequently.

3.17 Revenue Recognition

The Group recognizes revenues in accordance with the following steps determined in accordance with Korean IFRS No.1115 Revenue from Contracts withCustomers.

•	Step 1: Identify the contract with a customer.
•	Step 2: Identify the performance obligations in the contract.
---	---
•	Step 3: Determine the transaction price.
---	---
•	Step 4: Allocate the transaction price to the performance obligations in the contract.
---	---
•	Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.
---	---

3.17.1 Interest income and expense

Interest income and expense on debt securities at fair value through profit or loss (excluding beneficiary certificates, equity investments, and other debt instruments), loans, financial instruments at amortized cost, and debt securities at fair value through other comprehensive income are recognized in the consolidated statement of comprehensive income using the effective interest method in accordance with Korean IFRS No.1109 Financial Instruments. The effective interest method is a method of calculating the amortized cost of a financial asset or a financial liability and allocating the interest income or interest expense over the relevant period.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

The effective interest rate is the rate that exactly discounts estimated future cash receipts or payments through the expected life of the financial instrument or, where appropriate, a shorter period, to the gross carrying amount of a financial asset or to the amortized cost of a financial liability. When calculating the effective interest rate, the Group estimates expected cash flows by considering all contractual terms of the financial instrument but does not consider expected credit losses. The calculation includes all fees and points paid (main components of effective interest rate only) or received between parties to the contract that are an integral part of the effective interest rate, transaction costs, and all other premiums or discounts. In those rare cases when it is not possible to reliably estimate the cash flows and the expected life of a financial instrument, the Group uses the contractual cash flows over the full contractual term of the financial instrument.

Interest income on impaired financial assets is recognized using the interest rate used to discount the expected cash flows for the purpose of measuring the impairment loss. Interest income on debt securities at fair value through profit or loss is also classified as interest income in the consolidated statement of comprehensive income.

3.17.2 Fee and commission income

The Group recognizes financial service fees in accordance with the purpose of charging the fees and the accounting standards of the financial instrument related to the fees earned.

3.17.2.1 Fees that are an integral part of the effective interest of a financial instrument

Such fees are generally treated as adjustments of effective interest rate. Such fees may include compensation for activities such as evaluating the borrower’s financial condition, evaluating and recording guarantees, collateral and other security arrangements, negotiating the terms of the instrument, preparing and processing documents, and closing the transaction and origination fees received on issuing financial liabilities at amortized cost. However, fees relating to the creation or acquisition of a financial instrument at fair value through profit or loss are recognized as revenue immediately.

3.17.2.2 Fees related to performance obligations satisfied over time

If the control of a good or service is transferred over time, the Group recognizes revenue related to performance obligations over the period of performance obligations. Fees charged in return for the services for a certain period of time, such as asset management fees, consignment business fees, etc. are recognized over the period of performance obligations.

3.17.2.3 Fees related to performance obligations satisfied at a point in time

Fees earned at a point in time are recognized as revenue when a customer obtains control of a promised good or service and the Group satisfies a performance obligation.

Commission on negotiation or participation in negotiation for the third party such as trading stocks or other securities, arranging merger and acquisition of business, is recognized as revenue when the transaction has been completed.

If the Group arranges a syndicated loan but does not participate in the syndicated loan or participates in the syndicated loan with the same effective profit as other participants, a syndication arrangement fee is recognized as revenue at the completion of the syndication service.

3.17.3 Net gains or losses on financial instruments at fair value through profit or loss

Net gains or losses on financial instruments at fair value through profit or loss (including changes in fair value, dividends, and gains or losses from foreign currency translation) include gains or losses on financial instruments as follows:

•	Gains or losses relating to financial instruments at fair value through profit or loss (excluding interest income<br>using the effective interest rate method)
•	Gains or losses relating to derivative financial instruments for trading (including derivative financial<br>instruments for hedging purpose but do not qualify for hedge accounting)
---	---

3.17.4 Dividend income

Dividend income is recognized in profit or loss when the right to receive payment is established. Dividend income is recognized as net gains or losses on financial instruments at fair value through profit or loss or other operating income depending on the classification of equity securities.

3.18Employee Compensation and Benefits

3.18.1 Post-employment benefits

3.18.1.1 Defined contribution plans

When an employee has rendered service to the Group during a period, the Group recognizes the contribution payable to a defined contribution plan in exchange for that service as post-employment benefits for the period.

3.18.1.2 Defined benefit plans

All post-employment benefits, other than defined contribution plans, are classified as defined benefit plans. The amount recognized as a net defined benefit liability is the present value of the defined benefit obligation less the fair value of plan assets at the end of the reporting period.

The present value of the defined benefit obligation is calculated annually by a qualified actuary using the projected unit credit method. The rate used to discount post-employment benefit obligations is determined by reference to market yields at the end of the reporting period on high quality corporate bonds. The currency and term of the corporate bonds are consistent with the currency and estimated term of the post-employment benefit obligations. Actuarial gains and losses resulting from changes in actuarial assumptions and experience adjustments are recognized in other comprehensive income.

When the present value of the defined benefit obligation minus the fair value of plan assets results in an asset, it is recognized to the extent of the present value of any economic benefits available in the form of refunds from the plan or reductions in future contributions to the plan.

Past service cost is the change in the present value of the defined benefit obligation for employee service in prior periods, resulting from the introduction or changes to a defined benefit plan. Such past service cost is immediately recognized as an expense for the period.

3.18.2 Short-term employee benefits

Short-term employee benefits are employee benefits that are expected to be settled wholly before twelve months after the end of the annual reporting period in which the employees render the related service. When an employee has rendered service to the Group during an accounting period, the Group recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service as an expense for the period.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

The expected cost of profit-sharing and bonus payments is recognized as liabilities when the Group has a present legal or constructive obligation to make payments as a result of past events, such as service rendered by employees, and a reliable estimate of the obligation can be made.

3.18.3 Share-based payment

The Group provides its executives and employees with stock grants and mileage stock programs. When stock grants are exercised, the Group can either select to distribute shares of KB Financial Group Inc., the Parent Company or compensate in cash based on the share price. When mileage stock is exercised, the Group pays the amount equivalent to share price of KB Financial Group Inc. in cash.

For a share-based payment transaction in which the terms of the arrangement provide the Group with the choice of whether to settle in cash or by issuing equity instruments, the Group accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions because the Group determines that it has a present obligation to settle in cash based on a past practice and a stated policy of settling in cash. Therefore, the Group measures the liability incurred as consideration for the service received at fair value and recognizes related expense and accrued expense over the vesting periods. For mileage stock, the Group accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions, which are recognized as expenses and accrued expenses at the time of vesting.

Until the liability is settled, the Group remeasures the fair value of the liability at the end of each reporting period and at the date of settlement, with any changes in fair value recognized in profit or loss as share-based payments.

3.18.4 Termination benefits

Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or an employee’s decision to accept an offer of benefits in exchange for the termination of employment. The Group recognizes a liability and expense for termination benefits at the earlier of the following dates; when the Group can no longer withdraw the offer of those benefits and when the Group recognizes costs for a restructuring that is within the scope of Korean IFRS No.1037 and involves the payment of termination benefits. If the termination benefits are not expected to be settled wholly before twelve months after the end of the annual reporting period, then the termination benefits are discounted to present value.

3.19 Income Tax Expense

Income tax expense comprises current tax expense and deferred income tax expense. Current and deferred income taxes are recognized as income or expense and included in profit or loss for the period, except to the extent that the tax arises from (a) a transaction or event which is recognized, in the same or a different period, outside profit or loss, either in other comprehensive income or directly in equity and (b) a business combination.

3.19.1 Current income tax

Current income tax is the amount of income tax payable (recoverable) in respect of the taxable profit (tax loss) for a period. A difference between the taxable profit and accounting profit may arise when income or expense is included in accounting profit in one period but is included in taxable profit in a different period. Differences may also arise if there is revenue that is exempt from taxation, or expense that is not deductible in determining taxable profit (loss). Current income tax liabilities for the current and prior periods are measured using the tax rates that have been enacted or substantively enacted by the end of the reporting period.

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

The Group offsets current income tax assets and current income tax liabilities if, and only if, the Group (a) has a legally enforceable right to offset the recognized amounts and (b) intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

3.19.2 Deferred income tax

Deferred income tax is recognized, using the asset-liability method, on temporary differences arising between the tax-based amount of assets and liabilities and their carrying amount in the financial statements. Deferred income tax liabilities are recognized for all taxable temporary differences and deferred income tax assets are recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized. However, deferred income tax liabilities are not recognized if they arise from the initial recognition of goodwill; deferred income tax assets and liabilities are not recognized if they arise from the initial recognition of an asset or liability in a transaction that is not a business combination, and at the time of the transaction, affects neither accounting nor taxable profit or loss.

The Group recognizes a deferred income tax liability for all taxable temporary differences associated with investments in subsidiaries and associates, except to the extent that the Group is able to control the timing of the reversal of the temporary difference, and it is probable that the temporary difference will not reverse in the foreseeable future.

The carrying amount of a deferred income tax asset is reviewed at the end of each reporting period. The Group reduces the carrying amount of a deferred income tax asset to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred income tax asset to be utilized.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred income tax liabilities and deferred income tax assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

The Group offsets deferred income tax assets and deferred income tax liabilities if, and only if the Group has a legally enforceable right to offset current income tax assets against current income tax liabilities and the deferred income tax assets and the deferred income tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current income tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred income tax liabilities or assets are expected to be settled or recovered.

3.19.3 Uncertain tax positions

Uncertain tax positions arise from tax treatments applied by the Group which may be challenged by the tax authorities due to the complexity of the transaction or different interpretation of the tax laws, such as a claim for rectification, a claim for a refund related to additional tax or a tax investigation by the tax authorities. The Group recognizes its uncertain tax positions in the consolidated financial statements in accordance with Korean IFRS No.1012 and Interpretation of Korean IFRS No.2123. The income tax asset is recognized if a tax refund is probable for taxes levied by the tax authority, and the amount to be paid as a result of the tax investigation and others is recognized as the current tax payable. However, penalty tax and additional refund on tax are regarded as penalty or interest and are accounted for in accordance with Korean IFRS No.1037.

3.19.4 Global Minimum Tax

The Group is subject to the global minimum tax under Pillar 2 legislation and has applied the exemption from recognizing and disclosing related deferred tax.

3.20 Transactions with the Trust Accounts

The Group accounts for trust assets separately from its own assets in accordance with the Financial Investment Services and Capital Markets Act. The borrowings from trust accounts represent transfer of funds in trust accounts into banking accounts. Such borrowings from trust accounts are recorded as receivables from the banking accounts in the trust accounts and as borrowings from trust accounts in the banking accounts. The Group earns trust fees from the trust accounts for its management of trust assets and operations. The reserves for future profits and losses are set up in the trust accounts for profits and losses related to those trust funds with a guarantee of the principal or of the principal and a certain minimum rate of return in accordance with the relevant laws and regulations applicable to trust operations. The reserves are used to provide for the losses on such trust funds and, if the losses incurred are in excess of the reserves, the excess losses are compensation paid as a loss on trust management in other operating expenses and the trust accounts recognize the corresponding compensation as compensation from banking accounts.

3.21 Leases

The Group as a lessor recognizes lease payments from operating leases as income on a straight-line basis over the lease term. Initial direct costs incurred in obtaining an operating lease are added to the carrying amount of the underlying asset and recognized as expense over the lease term on the same basis as lease income. The respective leased assets are included in the consolidated statement of financial position based on their nature.

A lessee is required to recognize a right-of-use asset (lease assets) representing its right to use the underlying leased asset and a lease liability representing its obligation to make lease payments. Assets and liabilities arising from a lease are initially measured at the present value.

Lease liabilities include the net present value of the following lease payments:

•	Fixed payments (including in-substance fixed payments), less any lease<br>incentives receivable
•	Variable lease payments that depend on an index or a rate
---	---
•	Amounts expected to be payable by the lessee under residual value guarantees
---	---
•	The exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and<br>
---	---
•	Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to<br>terminate the lease
---	---

The lease payments are discounted using the interest rate implicit in the lease if that rate can be readily determined. If that rate cannot be readily determined, the lessee’s incremental borrowing rate is used, which is the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment.

Right-of-use assets are measured at cost comprising the following:

•	The amount of the initial measurement of the lease liability

Kookmin Bank and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

•	Any lease payments made at or before the commencement date, less any lease incentives received<br>
•	Any initial direct costs incurred by the lessee, and
---	---
•	An estimate of restoration costs
---	---

However, the Group can elect not to apply the requirements of Korean IFRS No.1116 to short-term lease (lease that, at the commencement date, has a lease term of 12 months or less) and leases for which the underlying asset is of low value (for example, underlying leased asset under USD 5,000). The Group applies the exemption of the standard for one time lease of real estate (for training purpose) and leases of low-value assets (underlying assets less than ~~W~~ 5 million or USD 5,000).

The right-of-use asset is depreciated from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term.

For sale and leaseback transactions, the Group applies the requirements of Korean IFRS No.1115 Revenue from Contracts with Customers, to determine whether the transfer of an asset is accounted for as a sale of that asset.

3.22 Operating Segments

The Group identifies its operating segments based on internal reports which are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance.

Segment information includes items which are directly attributable and can be allocated to the segment on a reasonable basis.

This note regarding financial risk management provides information about the risks that the Group is exposed to and about its objectives, policies, risk assessment and management procedures, and capital management. Additional quantitative information is disclosed throughout the consolidated financial statements.

The Group’s risk management system focuses on efficiently supporting long-term strategy and management decisions of each business group through increased risk transparency, spread of risk management culture, prevention of risk transfer between risk types, and preemptive response to rapidly changing financial environments. Credit risk, market risk, liquidity risk, and operational risk are recognized as the Group’s significant risks and measured and managed by quantifying them in the form of internal capital or Value at Risk (“VaR”) using statistical methods.

4.1.2 Risk management organization

4.1.2.1 Risk Management Committee

4.1.2.4 Risk Management Group

The Risk Management Group manages detailed risk management policies, procedures, and business processes.

4.2 Credit Risk

4.2.1 Overview of credit risk

Credit risk is the risk of loss from the portfolio of assets held due to the counterparty’s default, breach of contract, and deterioration of credit quality. For risk management reporting purposes, the Group considers all factors of credit risk exposure, such as default risk of individual borrowers, country risk, and risk of specific sectors. The Group defines default as the definition applied to the calculation of Capital Adequacy Ratio under the new Basel Accord (Basel III).

4.2.2 Credit risk management

The Group measures the expected loss and internal capital for the assets subject to credit risk management, including on-balance and off-balance sheet assets, and uses them as management indicators. The Group allocates and manages credit risk internal capital limits.

In addition, to prevent excessive concentration of exposures by borrower and industry, the total exposure limit at the Group level is introduced, applied, and managed to control the credit concentration risk.

All of the Group’s loan customers (individuals and corporates) are assigned a credit rating and managed by a credit evaluation system. For individuals, the credit rating is evaluated by utilizing personal information, income and job information, asset information, and bank transaction information. For corporates, the credit rating is evaluated by analyzing and utilizing financial and non-financial information which measures current and future corporate value and ability to repay the debt. Also, the extent to which corporates have the ability to meet debt obligations is comprehensively considered.

The credit rating, once assigned, serves as the fundamental instrument in the Group’s credit risk management, and is applied in a wide range of credit risk management processes, including credit approval, credit limit management, loan pricing, and assessment of allowances for credit losses. For corporates, the Group conducts a regular credit evaluation at least once a year, and the review and supervision departments regularly validate the adequacy of credit ratings to manage credit risks.

In order to establish a credit risk management system, the Group manages credit risk by forming a separate risk management organization. In particular, independently of the Sales Group, the Credit Management & Analysis Group, Retail Customer Group and SME/SOHO Customer Group are in charge of loan policy, loan system, credit rating, credit analysis, follow-up management, and corporate restructuring. The Risk Management Group is responsible for establishing policies on credit risk management, measuring and limiting internal capital of credit risk, setting credit limits, credit review, and verification of credit rating models.

4.2.4 Credit risk of loans

The Group maintains allowances for loan losses associated with credit risk of loans to manage its credit risk.

The Group assesses expected credit losses and recognizes loss allowances of financial assets at amortized cost and financial assets at fair value through other comprehensive income (debt instruments). Financial assets at fair value through profit or loss are excluded. Expected credit losses are a probability-weighted estimate of possible credit losses occurring in a certain range by reflecting supportable information that is reasonably available at the end of the reporting period without undue cost or effort, including information about past events, current conditions, and forecasts of future economic conditions. The Group measures the expected credit losses of loans classified as financial assets at amortized cost, by deducting allowances for credit losses in the consolidated statements of financial position. The expected credit losses of loans classified as financial assets at fair value through other comprehensive income are presented in other comprehensive income in the consolidated statements of financial position.

4.3 Liquidity Risk

4.3.1 Overview of liquidity risk

Liquidity risk is a risk that the Group becomes insolvent due to the mismatch between the inflow and outflow of funds, unexpected cash outflows, or a risk of loss due to financing funds at a high interest rate or disposing of securities at an unfavorable price due to lack of available funds. The Group manages its liquidity risk through analysis of the contractual maturity of interest-bearing assets and liabilities, assets and liabilities related to the other inflows and outflows of funds, and off-balance sheet items related to the inflows and outflows of funds such as currency derivative instruments and others.

4.3.2 Liquidity risk management and indicator

The liquidity risk is managed by comprehensive risk management policies and Asset Liability Management (“ALM”) risk management guidelines set forth in these policies that apply to all risk management policies and procedures that may arise throughout the overall business of the Group.

The Group establishes a liquidity risk management strategy, including objectives of liquidity risk management, management policies, and internal control systems, and obtains approval from the Risk Management Committee. The Risk Management Committee establishes the Risk Management Council for efficient risk management to supervise the establishment and implementation of policies according to risk management strategies.

The Group calculates and manages the Liquidity Coverage Ratio (“LCR”), Net Stable Funding Ratio (“NSFR”), liquidity ratio, maturity mismatch ratio and liquidity stress testing results for all transactions and off-balance sheet transactions, that affect the cash flows in Korean won and foreign currency funds raised and operated for the management of liquidity risks and periodically reports them to the Risk Management Council and the Risk Management Committee.

4.3.3 Analysis of remaining contractual maturity of financial liabilities

The cash flows disclosed in the maturity analysis are undiscounted contractual amounts including principal and future interest and payments; as such, amounts in the table below do not match with those in the consolidated statements of financial position which are based on discounted cash flows. The future interest payments of floating-rate liabilities are calculated on the assumption that the current interest rate is the same until maturity.

4.4 Market Risk

4.4.1 Concept

Market risk refers to risks that can result in losses due to changes in market factors such as interest rate, stock price, and foreign exchange rate, etc., which arise from securities, derivatives, and others. The most significant risks associated with trading positions are interest rate risk, currency risk, and additional risks including stock price risk. The non-trading position is also exposed to interest rate risk. The Group manages the market risks by dividing them into those arising from the trading position and those arising from the non-trading position.

4.4.2 Risk management

The Group sets and monitors internal capital limits for market risk and interest rate risk to manage the risks of trading and non-trading positions. In order to manage market risk efficiently, the Group maintains risk management systems and procedures such as trading policies and procedures, market risk management guidelines for trading positions, and ALM risk management guidelines for non-trading positions. The entire process is carried out through the approval by the Risk Management Council and the Risk Management Committee of the Group.

The Group’s Risk Management Council establishes and enforces overall market risk management policies for market risk management and decides to establish position limits, loss limits, VaR limits, and approves non-standard new products. In addition, the Market Risk Management Subcommittee, chaired by Chief Risk Officer (“CRO”), is a practical decision-making body for market risk management and determines position limits, loss limits, VaR limits, sensitivity limits, and scenario loss limits for each department of the business group.

4.4.2 Risk management(cont’d)

The Asset-Liability Management Committee (“ALCO”) determines interest rate and commission operating standards and ALM operation policies and enacts and revises relevant guidelines. The Risk Management Council monitors the establishment and enforcement of ALM risk management policies and enacts and revises ALM risk management guidelines. Interest rate risk limits are set based on future asset and liability positions and expected interest rate volatility, which reflect annual business plans. The Financial Planning Department and the Risk Management Department regularly measure and monitor interest rate risk and report the status and limit of interest rate risk including changes in Economic Value of Equity (“ΔEVE”), changes in Net Interest Income (“ΔNII”), and duration gap to the ALCO and the Risk Management Council on a monthly basis, and to the Risk Management Committee on a quarterly basis. To ensure the adequacy of interest rate risk and liquidity risk management, the Risk Management Department assigns the limits, monitors and reviews the procedures and tasks of ALM operations conducted by the financial planning department, and reports related matters to the management independently.

4.4.3 Trading position

4.4.3.1 Definition of a trading position

The trading position, which is subject to market risk management, includes interest rate position and stock position held for short-term trading profit. The Group also includes and manages all foreign currency positions in our trading positions. The trading position subject to market risk management is the trading position defined in “Trading Policy and Guidelines” and the basic requirements for the trading position are as follows:

•	The target position has no restrictions on the sale, the daily fair value assessment should be made, and the<br>embedded significant risk can be hedged in the market.
•	The trading position classification criteria should be clearly defined in the Trading Policy and Guidelines, and<br>the trading position should be managed by a separate trading department.
---	---
•	The target position must be operated according to the documented trading strategy, and the management of position<br>limit must be carried out.
---	---
•	The specialized dealer or operating department shall have the authority to execute the transaction without prior<br>approval from the Risk Management Department, etc. within the predetermined limits of the target position.
---	---
•	The target positions should be periodically reported to management for risk management of the Group.<br>

4.4.3.2 Methods of observing market risk arising from trading positions

The group is required to calculate regulatory capital for all trading positions using the standard method through market risk management systems, following the adoption of Basel III market risk standard approach regulation in 2023.

Furthermore, risk control and management for derivative financial product transactions are conducted in accordance with regulations and guidelines set by the Financial Supervisory Service.

4.4.3.3 Standard Method

Market risk regulatory capital is calculated using the Basel III standard method as follows.

[Market risk regulatory capital = (a) Sensitivity-based risk + (b) Default risk + (c) Residual risk]

•	Sensitivity-based risk, which forms the basis of the Basel III standard method for market risk, involves<br>calculating the expected losses for each risk factor by applying and aggregating the risk weights and correlation coefficients specified by the Basel Committee.
•	Default risk is the risk that arises from the issuer default of securities and derivatives that are not<br>considered in sensitivity-based risk. It is calculated by applying risk weights based on the issuer’s credit rating and other factors.
---	---
•	Residual risk is the risk that is not considered by sensitivity-based and default risk calculations. It is<br>calculated by applying a certain percentage determined by the Basel Committee to the nominal value of structured products and other non-standard underlying assets.
---	---
						Description
---	---	---	---	---	---	---
Sensitivity- based risk		Interest rate risk group		GIRR		The risk associated with risk-free interest rates (typically OIS rates) defined by currency and maturity.
				CSR		The risk associated with the issuer’s interest rate credit spread, defined by creditworthiness and sector.
		Equity risk group				The risk factors associated with equity, defined by market capitalization, economic conditions, and sector
		Foreign exchange risk group				The risk factors associated with exchange rate, defined by currency pairs
		Commodity risk group				The risk factors associated with commodities, defined by commodity types.
Default risk						Issuer default risk in securities (bonds, etc.) and derivatives.
Residual risk						Additional risks imposed on non-standard underlying asset products, etc.

4.4.3.3 Standard Method(cont’d)

The table below represents regulatory capital for sensitivity-based risk, default risk, and residual risk of trading positions at the end of 2025 and 2024, respectively.

Default risk		63,128	52,293
Residual risk		1,243	1,070

Total		491,826	471,119

Risks arising from trading positions primarily result from interest rate, equity price, and foreign exchange movements. The causes of such risks and the related risk management methods are as follows:

4.4.3.3.1 Interest Rate Risk

Interest rate risk in trading positions mainly arises from debt securities denominated in Korean won. The Group’s trading strategy is to generate short-term trading gains from fluctuations in interest rates. Interest rate risk related to the major trading portfolio is managed using sensitivity analysis (Price Value of a Basis Point: PVBP).

4.4.3.3.2 Stock Price Risk

Stock price risk mainly arises from stock spot positions held by principal-guaranteed trusts and stock-related derivative positions held by the market trading division. Such stock price risk is managed through sensitivity limits and other risk control measures.

4.4.3.3.3 Currency Risk

Foreign exchange risk arises from holding assets, liabilities, and currency-related derivatives denominated in foreign currencies other than Korean won. The majority of the net open foreign currency exposure arises in U.S. dollars and Indonesian rupiah. Such foreign exchange risk is managed through limits on net open foreign currency exposures and other internal control mechanisms.

4.4.4 Non-trading position (Interest Rate Risk of Banking Book (“IRRBB”))

4.4.4.1 Definition of IRRBB

IRRBB is a change in equity and earnings due to the changes in value of interest-sensitive assets and liabilities, etc., and is measured by ΔEVE and ΔNII.

4.4.4.2 The Bank’s overall interest rate risk management and mitigation strategy

4.4.4.2 The Bank’s overall interest rate risk management and mitigation strategy(cont’d)

Independent internal and external audit department regularly check the process of identifying, measuring and monitoring interest rate risk. The interest rate risk model adequacy test is carried out regularly at least once a year by the verification department independent of the management department.

4.4.4.3 Main modeling assumption used for the Bank’s interest rate risk measurement system for internal management

The bank measures adverse fluctuations in economic value resulting from changes in interest rates following the interest rate risk calculation standards set by the Financial Supervisory Service.

4.4.4.4 The Bank’s interest rate risk hedging methodology and related accounting

The Bank hedges interest rate risk through back-to-back interest rate swap transactions, which are the same as interest payment cash flows. The Bank officially documents and manages the risk management strategy for hedge accounting, risk management objectives, hedging relationship, and assessment method for hedge effectiveness.

4.4.4.5 Main assumptions used for calculating ΔEVE, ΔNII

The Bank calculates interest rate risk, including all cash flow of interest-sensitive assets and liabilities, and off-balance sheet items in the banking book. ΔEVE assumes a run-off balance sheet where the existing bank account positions are amortized and not replaced by new businesses. In addition, the contractual interest rate, including commercial margins and other spread components, is applied to generate cash flows. When discounting cash flows, ΔEVE is calculated by applying risk-free interest rate that do not include commercial margins and other spread components.

ΔNII assumes a constant balance sheet where maturing or repricing cash flows during the target management period are replaced by new cash flows with identical features. The interest rate risk is calculated for the interest rate shock scenario by adding up only if the risk is a loss for each currency. After classifying into retail/transactional, retail/non-transactional, and wholesale according to customers and regular transactions, the average repricing maturity of non-maturity deposits is determined by taking into account the proportion of core deposits and cap on average maturity of core deposits for each category. The average repricing maturity of non-maturity deposits is 2.5 years for core deposits, 1 day for non-core deposits, and the longest repricing maturity is five years. The prepayment rate of fixed rate loans and term deposit redemption ratio are estimated by dividing the amount of prepayment amount and redemption amount during the previous month by the balance at the end of the previous month, respectively.

4.5 Operational Risk

4.5.1 Concept

The Group defines operational risk as loss risk arising from improper or incorrect internal procedures, personnel, systems or external events and includes financial and non-financial risks.

4.5.2 Risk management

The purpose of operational risk management is not only to comply with supervisory and regulatory requirements, but also to spread risk management culture, strengthen internal control, improve processes, and provide timely feedback to management and all employees. The Group established a Business Continuity Planning (BCP) to carry out continuous work in emergency situations and established alternative facilities. The Group conducts simulation training for headquarters and IT departments to check the business continuity framework.

4.6 Capital Management

The Group complies with the capital adequacy standard established by the financial supervisory authority. This capital adequacy standard is based on Basel III revised by Basel Committee on Banking Supervision in Bank for International Settlements (“BIS”) in June 2011 and was implemented in Korea in December 2013.

According to this standard, the Group is required to maintain a minimum capital adequacy ratio to risk-weighted assets (Common Equity Tier 1 Capital ratio of 4.5%, Tier 1 Capital ratio of 6.0%, and Total Capital ratio of 8.0%) as of December 31, 2025. Capital Conservation Buffer of 2.5%, a Countercyclical Capital Buffer of 1.0%, and Capital Requirement of Domestic Systemically Important Bank (D-SIB) of 1.0% are additionally applied. Therefore, the Group is required to maintain a capital adequacy ratio including a minimum capital adequacy ratio and additional capital requirements (Common Equity Tier 1 Capital ratio of 9.0%, Tier 1 Capital ratio of 10.5%, and Total Capital ratio of 12.5%).

The Group’s capital is classified into three categories in accordance with the Detailed Regulations on Supervision of Banking Business as follows:

•	Common Equity Tier 1 Capital: Common equity Tier 1 Capital is the first to take losses of the Group and is the<br>last to be compensated in liquidation of the Group and not repaid except for liquidation. It includes capital, capital surplus, retained earnings, non-controlling interests of the consolidated subsidiaries,<br>accumulated other comprehensive income, and other capital surplus, etc.
•	Additional Tier 1 Capital: Additional Tier 1 Capital includes capital, capital surplus, etc. related to the<br>issuance of capital securities of a permanent nature that meet the conditional capital securities requirements.
---	---
•	Tier 2 Capital: Tier 2 Capital means capital that can compensate for losses of the Group upon liquidation,<br>including (a) the amount of subordinated bonds with maturity of not less than 5 years that meet the conditional capital securities requirements, and (b) the allowances for credit losses accumulated on the loans which are classified as<br>normal or precautionary in accordance with Regulations on Supervision of Banking Business, and others.

4.6 Capital Management(cont’d)

The risk-weighted assets are the magnitude of assets that reflect the risk that the Group has to bear, including risks inherent in all assets, errors in the operation of internal processes, and risk of loss that may arise from external events. The Group calculates risk-weighted assets by each risk (credit risk, market risk, and operational risk) based on the Detailed Regulations on Supervision of Banking Business and uses them to calculate capital adequacy ratio. The Group complied with external capital adequacy requirements as of December 31, 2025 and 2024.

Apart from the capital adequacy ratio, the Group evaluates and manages capital adequacy through internal policies. The evaluation of capital adequacy compares the size of available capital (the amount of capital actually available) to the size of internal capital (the amount of capital required to cover all the significant risks faced by the Group under its target credit rating), which monitors financial soundness and provides a risk-adjusted performance measurement basis. The internal capital for capital adequacy assessment is calculated by adding the results of a stress test and other additional capital requirements to the internal capital calculated for each individual risk.

The Risk Management Committee of the Group determines the risk appetite of the Group, allocates internal capital by risk type and business group, and each business group operates capital efficiently within the range of the allocated internal capital. The Risk Management Department of the Group monitors internal capital limit management and reports it to management and the Risk Management Committee. If the limit of internal capital is expected to be exceeded, the Group’s capital adequacy management is carried out through review and approval by the Risk Management Committee in advance.

Details of the Group’s capital adequacy ratio in accordance with Basel III requirements as of December 31, 2025 and 2024, are as follows:

(In millions of Korean won)
Total Capital:		41,604,455	40,573,940
Tier 1 Capital		36,960,176	35,059,009

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. The Group discloses the fair value of each class of assets and liabilities in a way that permits it to be compared with its carrying amount at the end of each reporting period. The best evidence of fair value of financial instruments is a quoted price in an active market.

6.1.1 Carrying amount and fair value of financial assets and liabilities by category as of December 31, 2025 and 2024, are as follows (cont’d)

Methods of determining fair value of financial instruments are as follows:

Cash and due from financial institutions		Fair value of cash is the same as its carrying amount. Carrying amount of demand deposit and settlement deposit is a reasonable approximation of fair value because these financial instruments do not have a fixed maturity and are<br>receivable on demand. Fair value of general deposits is measured using a Discounted Cash Flow (“DCF”) Model.
Securities,<br><br><br>Due from financial institutions and deposits indexed to gold price		Fair value of securities and others that are traded in an active market and due from financial institutions and deposits indexed to the gold price is determined using the quoted prices. If there is no quoted price, fair value is<br>determined using external professional valuation institutions. The institutions use one or more valuation techniques that are deemed appropriate considering the characteristics of the financial instruments including a DCF Model, MonteCarlo<br>Simulation, Free Cash Flow to Equity Model, Comparable Company Analysis, Dividend Discount Model, and Net Asset Value Method.
Loans		Fair value of loans is determined using a DCF Model and independent external professional valuation institutions. Fair value measured using a DCF Model is determined by discounting the expected cash flows, which are contractual cash<br>flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Derivatives		Fair value of exchange traded derivatives is determined using quoted prices in an active market, and fair value of OTC derivatives is determined using valuation techniques. The Group uses internally developed valuation models that<br>are widely used by market participants to determine fair value of plain vanilla OTC derivatives including options, interest rate swaps, and currency swaps, based on observable market parameters. However, some complex financial instruments are valued<br>using appropriate models developed from generally accepted market valuation models including a Finite Difference Method (“FDM”), MonteCarlo Simulation, and Tree Model or valuation results from independent external professional valuation<br>institutions. For OTC derivatives, the credit risk of the counterparty and the Group’s own credit risk are applied through a credit valuation adjustment method.
Deposits		Carrying amount of demand deposits is a reasonable approximation of fair value because they do not have a fixed maturity and are payable on demand. Fair value of time deposits is determined using a DCF Model discounting the expected<br>cash flows, which are contractual cash flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Borrowings		Carrying amount of overdrafts in foreign currency is a reasonable approximation of fair value because they do not have a fixed maturity and are payable on demand. Fair value of other borrowings is determined using a DCF<br>Model.
Debentures		Fair value is determined using the valuation results (DCF Model) of external professional valuation institutions, which are calculated using market inputs.
Other financial assets and other financial liabilities		Carrying amount is a reasonable approximation of fair value because other financial assets and other financial liabilities are temporary accounts used for other various transactions, and their maturities are relatively short or not<br>defined.

6.1.2 Fair value hierarchy

The Group believes that valuation techniques used for measuring the fair value of financial instruments are reasonable and that the fair value recognized in the consolidated statement of financial position is appropriate. However, the fair value of the financial instruments recognized in the consolidated statement of financial position may be different if other valuation techniques or assumptions are used. Additionally, as there are a variety of valuation techniques and assumptions used in measuring fair value, it may be difficult to reasonably compare the fair value with that of other financial institutions.

The Group classifies and discloses fair value of the financial instruments into the three fair value levels as follows:

Level 1:		The fair values are based on quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date.
Level 2:		The fair values are based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3:		The fair values are based on unobservable inputs for the asset or liability.

The fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. If an observable input requires an adjustment using an unobservable input and that adjustment results in a significantly higher or lower fair value measurement, the resulting measurement would be categorized within Level 3 of the fair value hierarchy.

6.2 Disclosure of Fair Value Hierarchy Level 3

6.2.1 Valuation policy and process of Level 3 fair value

The Group uses an external, independent and qualified valuation service in addition to internal valuation models to determine the fair value of financial instruments at the end of every reporting period.

If the changes in situation and events cause transfers between the fair value hierarchy level for a financial asset or liability occur, the Group’s policy is to recognize such transfers as having occurred at the beginning of the reporting period.

6.2.3.2 Sensitivity analysis of changes in unobservable inputs

Sensitivity analysis of financial instruments is performed to measure favorable and unfavorable changes in fair value of financial instruments which are affected by unobservable parameters, using a statistical technique. When the fair value is affected by more than one input parameter, the amounts represent the most favorable or most unfavorable outcome. Level 3 financial instruments subject to sensitivity analysis are debt securities, loans, equity-related derivatives, currency-related derivatives, interest rate-related derivatives, and other derivatives whose fair value changes are recognized in profit or loss as well as equity securities whose fair value changes are recognized in profit or loss or other comprehensive income or loss.

Results of the sensitivity analysis of changes in unobservable inputs as of December 31, 2025 and 2024, are as follows:

6.2.4 Day one gains or losses

When the Group measures the fair value of OTC derivatives using inputs that are not based on observable market data, there could be a difference between the transaction price and the amount determined using that valuation technique. In these circumstances, the fair value of financial instruments is recognized as the transaction price, and the difference is not recognized in profit or loss but deferred and amortized using the straight-line method over the life of the financial instrument. When the fair value of the financial instruments is subsequently determined using observable market inputs, the remaining deferred amount is recognized in profit or loss.

Changes in deferred day one gains or losses for the years ended December 31, 2025 and 2024, are as follows:

(In millions of Korean won)
Balance at the beginning of the year (A)	(2,662	)	(4,707	)

6.4.2 Bonds sold under repurchase agreements and loaned securities

The Group continues to recognize the financial assets related to bonds sold under repurchase agreements and securities lending transactions in the consolidated statement of financial position since those transactions are not qualified for derecognition even though the Group transfers the financial assets. Bonds sold under repurchase agreements are sold on the condition that they will be repurchased at a fixed price, and loaned securities will be returned at the expiration of the loan period. Thus, the Group retains substantially all the risks and rewards of ownership of the financial assets.

The carrying amount of transferred assets and related liabilities as of December 31, 2025 and 2024, are as follows:

	December 31, 2025

6.4.3 Liquidation of financial assets

The consolidated structured entities securitized the loans held by the Group and issued asset-backed securities. As a result of these transactions, the contractual cash flow of the securitized assets is generally transferred to the holders of the asset-backed securities, and the Group is contractually obligated to make cash payment to one or more recipients in the purchase commitment and other arrangements for all the transferred financial assets that are not derecognized on the reporting date in connection with the securitization of financial assets.

The carrying amount of underlying assets and liabilities related to securitization transactions as of December 31, 2025 and 2024, are as follows:

(In millions of Korean won)

6.5 Offsetting Financial Assets and Financial Liabilities

The Group enters into International Swaps and Derivatives Association (“ISDA”) master netting agreements and other similar arrangements with the Group’s OTC derivative and spot exchange counterparties. Similar netting agreements are also entered into with the Group’s (a) sales or purchases of bonds under repurchase agreements and (b) securities lending and borrowing transactions, etc. Pursuant to these agreements, in the event of default by one party, contracts are to be terminated and receivables and payables are to be offset. As the Group has the legal right of offset and settles in net amount, domestic exchange settlement debits and domestic exchange settlement credits are recognized in its net settlement balance in the consolidated statement of financial position. Other financial instruments such as account receivables and account payables related to listed securities, and derivatives or OTC derivatives settled by the central clearing house are also recognized in its net settlement balance in the consolidated statement of financial position as the Group has the legal right of offset and settles in net amount.

9. Derivative Financial Instruments and Hedge Accounting

The Group engages in derivative trading activities to hedge the interest rate risk and currency risk arising from the Group’s own assets and liabilities. In particular, the Group applies fair value hedge accounting using interest rate swaps and interest rate futures to hedge the risk of changes in fair value due to the changes in interest rate of debentures, deposits, and debt securities at fair value through other comprehensive income. Also, the Group applies cash flow hedge accounting using interest rate swaps to hedge the risk of changes in cash flows of debentures in foreign currencies, and borrowings in foreign currencies. In addition, the Group applies net investments in foreign operations hedge accounting by designating debentures in foreign currencies as hedging instruments to hedge the currency risk of net investments in foreign operations.

^2^	As of December 31, 2025, the Group has fully recovered its investment; however, the liquidation has not<br>yet been completed, and the Group retains rights to the residual interest.

^3^	As of December 31, 2025 and 2024, the Group participates in the investment management committee but cannot<br>exercise control.

^4^	The investment in associates was reclassified from financial assets at fair value through profit or loss due to<br>termination of rehabilitation procedures.
---	---

Although the Group holds 20% or more of the ownership in several investment trusts including KB Hanbando BTL Private Special Asset Fund No.1, those investment trusts are excluded from associates because the Group’s influence on those trusts is limited according to the trust agreement. In addition, the Group holds 20% or more of its ownership in KLB Securities Co., Ltd. and one other company, but those companies are excluded from associates, because the Group’s influence on those companies is limited due to the status of those companies such as bankruptcy and rehabilitation proceedings.

15.4 Details of goodwill allocation to cash-generating units and related information for impairment testing as of December 31, 2025 are as follows:

^1^	The carrying amount of goodwill at the time of the impairment test
---	---
^2^	If the carrying amount of goodwill is bigger than the recoverable amount, it is indicated as a negative number.<br>
---	---

For impairment testing, goodwill is allocated to cash-generating units that are expected to benefit from the synergies of the business combination, and cash-generating units consist of an operating segment or units which are not larger than an operating segment. The Group recognized goodwill amounting to ~~W~~ 65,288 million arising from the merger of Housing & Commercial Bank, and the amounts of ~~W~~ 49,315 million and ~~W~~ 15,973 million were allocated to the retail banking and corporate banking, respectively. The Group acquired a 70% stake in KB PRASAC BANK PLC. with an acquisition date of April 10, 2020, and an additional 30% stake with an acquisition date of October 19, 2021. The goodwill recognized due to the business combination is ~~W~~ 185,725 million as of December 31, 2025. The Group acquired a 66.88% stake in PT Bank KB Indonesia Tbk. with an acquisition date of September 2, 2020, and the goodwill recognized due to the business combination is ~~W~~ 88,477 million as of December 31, 2025. Cash-generating units to which goodwill has been allocated are tested for impairment annually and whenever there is an indication that the unit may be impaired, by comparing the carrying amount of the unit including the goodwill with the recoverable amount of the unit. The valuation dates of the recoverable amounts of the KB PRASAC BANK PLC. and PT Bank KB Indonesia Tbk. are September 30, 2025 and December 31, 2025, respectively.

The recoverable amount of a cash-generating unit is measured at the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal is the amount obtainable from the disposal in an arm’s length transaction between knowledgeable, willing parties, after deducting the costs of disposal. If it is difficult to measure the amount obtainable from the disposal of the cash-generating unit, the disposal amount of a similar cash-generating unit in the past transaction is used by reflecting the characteristics of the cash-generating unit to be measured. If it is not possible to obtain reliable information to measure the fair value less costs of disposal, the Group uses the asset’s value in use as its recoverable amount. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit. The estimated future cash flows are based on the most recent financial budget approved by management with maximum period of 5 years. The future cash flows of retail banking and corporate banking after the projection period are estimated on the assumption that the future cash flows will increase by 1.0% per year. The key assumptions used for the estimation of the future cash flows are based on the market size and the Group’s market share.

The future cash flows of KB PRASAC BANK PLC. after five years are estimated on the assumption that the future cash flows will increase by 4.0% per year. The future cash flows of PT Bank KB Indonesia Tbk. after five years are estimated on the assumption that the future cash flows will increase by 3.0% per year. The key assumptions used for the estimation of the future cash flows are the GDP growth rate and the market size of Cambodia and Indonesia, and the recent growth rate of KB PRASAC BANK PLC. and PT Bank KB Indonesia Tbk. The discount rate is a pre-tax rate that reflects assumptions regarding risk-free interest rate, market risk premium, and the risks specific to the cash-generating unit.

Provisions for restoration costs are measured at the present value of the best estimate of future restoration costs for leased properties as of the end of the reporting period, discounted at an appropriate discount rate. The expenditure for restoration costs is expected to be incurred at the end of each lease contract, and the lease period is used to reasonably estimate the timing of the expenditure. Additionally, to estimate the expected restoration costs, the average actual restoration expenses of stores that underwent restoration work over the past three years and the three-year historical average inflation rate are used.

23. Net Defined Benefit Liabilities (Assets)

23.1 Defined Benefit Plan

The Group operates defined benefit plans which have the following characteristics:

•	The Group has the obligation to pay the agreed benefits to all its current and former employees.<br>
•	The Group assumes actuarial risk (that benefits will cost more than expected) and investment risk.<br>
---	---

The net defined benefit liabilities (assets) recognized in the consolidated statements of financial position are calculated in accordance with an actuarial valuation method using assumptions based on market data and historical data such as discount rate, future salary increase rate, and mortality. Actuarial assumptions may differ from actual results due to changes in the market conditions, economic trends, and mortality trends.

23.6 Details of significant actuarial assumptions used as of December 31, 2025 and 2024, are as follows:

	December 31, 2025	December 31, 2024
Discount rate (%)	4.00	3.60
Salary increase rate (%)	0.00 ~ 5.70	0.00 ~ 5.16
Turnover rate (%)	1.92 ~ 47.65	1.68 ~ 38.60

Mortality assumptions are based on the experience-based mortality table issued by Korea Insurance Development Institute in 2023.

23.7 Results of sensitivity analysis of significant actuarial assumptions as of December 31, 2025, are as follows:

		Effect on defined benefit obligation
	Changes inassumptions	Increase inassumptions	Decrease in<br>assumptions
Discount rate	0.5%p	3.15% decrease	3.35% increase
Salary increase rate	0.5%p	3.30% increase	3.13% decrease
Turnover rate	0.5%p	0.10% decrease	0.09% increase

The above sensitivity analysis is based on a change in an assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. The sensitivity of the defined benefit obligation to changes in significant actuarial assumptions is calculated using the same projected unit credit method used in calculating the defined benefit obligation recognized in the consolidated statement of financial position.

(In number of cases, in millions of Koreanwon)

Lawsuits	Amount			Description of the lawsuits		Status of the lawsuits
Claims on a return of redemption amount		60,281		The Bank invested the assets entrusted by OO Asset Management and OO Investment Trust Management in the Fairfield Sentry Limited (the<br>Fairfield Sentry Limited reinvested the assets in Bernard L. Madoff Investment Securities LLC managed by Bernard Madoff) and subsequently redeemed them and returned the proceeds to the beneficiaries. Following the occurrence of Ponzi scheme-related<br>losses, Bernard L. Madoff Investment Securities LLC is undergoing a liquidation process.<br> <br>The bankruptcy trustee of Bernard L. Madoff Investment Securities<br>LLC filed a lawsuit against the Bank, seeking the return of the redemption proceeds received by the Bank through Fairfield Sentry Limited		Application for dismissal by the defendant has been denied, and further proceedings are scheduled. [Related litigation is in progress at the<br>New York Southern District Federal Bankruptcy Court (10-3777) at the written complaint review stage]<br> <br>The financial<br>impact on the bank is not significant due to the possibility of winning the case.
Return of unjust enrichment		156,755		MTS Bank, which was transacting through correspondent accounts with the Bank, was listed on the OFAC (Office of Foreign Assets Control of the<br>U.S. Department of the Treasury) SDN (Specially Designated Nationals) List.

Responding to local court trial schedule (Following the first-instance judgment against the bank on December 2, 2025, currently<br>responding in the appellate proceedings)<br> <br>Due to compliance with U.S. OFAC regulations, it is difficult to easily predict the likelihood of winning the<br>lawsuit proceeding in the Russian court.<br> <br>However, the claim amount can be covered by the balance in the plaintiff’s account, and the bank is expected<br>to experience a financial impact equivalent to the delayed interest.

Independent Auditor’s Report

(English Translation of a Report Originally Issued in Korean)

To the Board of Directors and Shareholders of Kookmin Bank

Opinion

We have audited the separate financial statements of Kookmin Bank(the “Company”) which comprise the separate statements of financial position as at December 31, 2025 and 2024, and the separate statements of comprehensive income, separate statements of changes in equity and separate statements of cash flows for the years then ended, and notes to the separate financial statements, including material accounting policy information.

In our opinion, the accompanying separate financial statements present fairly, in all material respects, the separate financial position of Kookmin Bank as at December 31, 2025 and 2024, and its separate financial performance and its separate cash flows for the years then ended in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS).

Basis for Opinion

We conducted our audits in accordance with Korean Standards on Auditing. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are independent of the Company in accordance with the ethical requirements of the Republic of Korea that are relevant to our audit of the separate financial statements and we have fulfilled our other ethical responsibilities in accordance with the ethical requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Other Matter

Auditing standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to audit such separate financial statements may differ from those generally accepted and applied in other countries.

Responsibilities of Management and Those Charged withGovernance for the separate Financial Statements

Management is responsible for the preparation and fair presentation of the separate financial statements in accordance with Korean IFRS, and for such internal control as management determines is necessary to enable the preparation of separate financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the separate financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations.

Those charged with governance are responsible for overseeing the Company’s financial reporting process.

Auditor’s Responsibilities for the Audit of the separate Financial Statements

Our objectives are to obtain reasonable assurance about whether the separate financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Korean Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these separate financial statements.

As part of an audit in accordance with Korean Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

•	Identify and assess the risks of material misstatement of the separate financial statements, whether due to fraud<br>or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is<br>higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
•	Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are<br>appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control.
---	---
•	Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and<br>related disclosures made by management.
---	---
•	Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on<br>the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we<br>are required to draw attention in our auditor’s report to the related disclosures in the separate financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up<br>to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern.
---	---
•	Evaluate the overall presentation, structure and content of the separate financial statements, including the<br>disclosures, and whether the separate financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

2. Basis of Preparation

2.1 Application of KoreanIFRS

The Bank maintains its accounting records in Korean won and prepares statutory financial statements in the Korean language in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”). The accompanying separate financial statements have been translated into English from the Korean language separate financial statements.

The separate financial statements of the Bank have been prepared in accordance with Korean IFRS.

Korean IFRS are the standards and related interpretations issued by the International Accounting Standards Board (“IASB”) that have been adopted by the Republic of Korea.

The preparation of the separate financial statements requires the use of certain critical accounting estimates. Management also needs to exercise judgment in applying the Bank’s accounting policies. The areas that require a more complex and higher level of judgment or areas that require significant assumptions and estimations are disclosed in Note 2.4.

The separate financial statements have been prepared in accordance with Korean IFRS No.1027 Separate Financial Statements.

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

- Amendments of KoreanIFRS No.1021 “The Effects of Changes in Foreign Exchange Rates” and Korean IFRS No.1101 “First-time Adoption of International Financial Reporting Standards”—Lack of exchangeability

The amendments require the Bank to determine a spot exchange rate when exchangeability is lacking, and to disclose information on the nature and financial effects of the currency not being exchangeable into the other currency, the spot exchange rate(s) used, the estimation process, and the risks to which the Bank is exposed. These amendments do not have a significant impact on the financial statements.

2.1.2 The following new and amended standards have been published that are not mandatory for December 31, 2025 reporting period and have not been adopted by the Bank.

- Amendments of Korean IFRS No.1109 “Financial Instruments” and No.1107 “Financial Instruments:Disclosures”

The amendments respond to recent questions arising in practice. The amendments will be applicable from the accounting year beginning on or after January 1, 2026, and early adoption is permitted. The main changes are as follows. The Bank is reviewing the impact of these amendments on the financial statements. These amendments do not have a significant impact on the financial statements.

•	allow the consideration of a financial liability as settled (derecognized) through an electronic payment system<br>before the settlement date if certain criteria are met;
•	clarify and provide additional guidance for assessing whether a financial asset meets the solely payments of<br>principal and interest (SPPI) criterion;

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

2.1.2 The following new and amended standards have been published that are not mandatory for December 31, 2025 reporting period and have not been adopted by the Bank. (cont’d)

- Korean IFRS No.1118 Presentation and Disclosures inFinancial Statements

Korean IFRS No.1118 introduces new requirements to:

•	Present specified categories and defined subtotals in the statement of profit or loss
•	Provide disclosures on management-defined performance measures (MPMs) in the notes to the financial statements<br>
---	---
•	Improve aggregation and disaggregation.
---	---

The Bank is required to apply Korean IFRS No.1118 for annual reporting periods beginning on or after January 1, 2027, with earlier application permitted. The amendments to Korean IFRS No.1007 and Korean IFRS No.1033, as well as the revised Korean IFRS No.1008 and Korean IFRS No.1107, become effective when The Bank applies Korean IFRS No.1118. Korean IFRS No.1118 requires retrospective application with specific transition provisions. The Bank is reviewing the impact of these amendments on the financial statements.

2.2 Measurement Basis

The separate financial statements have been prepared based on the historical cost accounting model unless otherwise specified.

2.3 Functional and Presentation Currency

Items included in the financial statements of the Bank are measured using the currency of the primary economic environment in which the Bank operates (“functional currency”). The separate financial statements are presented in Korean won, which is the Bank’s functional and presentation currency.

2.4 Critical Accounting Estimates

The Bank applies accounting policies and uses judgments, accounting estimates, and assumptions that may have a significant impact on the assets (liabilities) and incomes (expenses) in preparing the separate financial statements. Management’s estimates of outcomes may differ from actual outcomes if management’s estimates and assumptions based on management’s best judgment are different from the actual environment.

Estimates and underlying assumptions are continually evaluated, and changes in accounting estimates are recognized in the period in which the estimates are changed and in any future periods affected.

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

Uncertainties in estimates and assumptions with significant risks that may result in material adjustments to the separate financial statements are as follows:

2.4.1 Income taxes

As the income taxes on the Bank’s taxable income is calculated by applying the tax laws of various countries and the decisions of tax authorities, there is uncertainty in calculating the final tax effect.

2.4.2 Fair value of financial instruments

2.4.3 Allowances and provisions for credit losses

The Bank recognizes and measures allowances for credit losses of debt instruments measured at amortized cost and debt instruments measured at fair value through other comprehensive income. Also, the Bank recognizes and measures provisions for credit losses of acceptances and guarantees, and unused loan commitments. Accuracy of allowances and provisions for credit losses is dependent upon estimation of expected cash flows of the borrower subject to individual assessment of impairment, and upon assumptions and variables of model used in collective assessment of impairment and estimation of provisions for credit losses of acceptances and guarantees, and unused loan commitments.

Allowances and provisions for credit losses (Allowances, acceptances and guarantees, and unused commitments)

Economic uncertainty persists due to government regulations affecting the real estate market and the downturn in the construction sector driven by oversupply, while prolonged high interest rates increase repayment burdens and may lead to a deterioration in asset quality. Accordingly, the Bank has reflected the potential impact on expected credit losses though a management overlay, based on a comprehensive review of vulnerable sectors in the event that COVID-19 related support measures expire. In addition, the Bank estimates relevant risk parameters based on a holistic review and incorporates forward-looking economic information into those parameters. The Bank will continue to monitor the impact of economic uncertainty and government policies on expected credit losses. Further details of the impact on expected credit losses are presented in Note 11.1 Changes in allowances for credit losses of loans measured at amortized cost and Note 22.2 Changes in provisions for credit losses of unused loan commitments, and

acceptances and guarantees.

2.4.4 Net defined benefit asset (liability)

The present value of the net defined benefit asset(liability) is affected by changes in the various factors determined by the actuarial method.

2.4.5 Impairment of goodwill

The recoverable amounts of cash-generating units are determined based on value-in-use calculations to test whether impairment of goodwill has occurred.

Notes to the Separate Financial Statements

December31, 2025 and 2024

3. Material Accounting Policies

The principal accounting policies applied in the preparation of these separate financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

3.1 Investments in Associates and Subsidiaries

Associates are entities over which the Bank has significant influence over the financial and operating policy decisions. Generally, if the Bank holds 20% or more of the voting power of the investee, it is presumed that the Bank has significant influence.

Subsidiaries are companies that are controlled by the Bank. 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. Also, the existence and effects of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Bank controls the investee. Subsidiaries are fully consolidated from the date when control is transferred to the Bank and de-consolidated from the date when control is lost.

Investments in associates and subsidiaries are accounted for at cost in accordance with Korean IFRS No.1027. However, beneficiary certificates in private equity fund which is consolidated is classified as financial assets at fair value through profit or loss in accordance with Korean IFRS No.1109 and measured at fair value in accordance with Korean IFRS No.1113.

The Bank determines at each reporting period whether there is any objective evidence that the investments in the associates and subsidiaries that are accounted for by cost method are impaired. If this is the case, the Bank calculates the amount of impairment as the difference between the recoverable amount of the associate or subsidiary and its carrying amount and recognizes the amount as non-operating expenses in the statement of comprehensive income.

3.2 Foreign Currency

3.2.1 Foreign currency transactions

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.2.2 Foreign operations

The results and financial position of a foreign operation, whose functional currency differs from the Bank’s presentation currency, are translated into the Bank’s presentation currency based on the following procedures.

On the disposal of a foreign operation, the cumulative amount of the exchange differences relating to that foreign operation, recognized in other comprehensive income and accumulated in the separate component of equity, is reclassified from equity to profit or loss (as a reclassification adjustment) when the gain or loss on disposal is recognized. On the partial disposal of a subsidiary that includes a foreign operation, the Bank re-attributes the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income to the non-controlling interests in that foreign operation. In any other partial disposal of a foreign operation, the Bank reclassifies to profit or loss only the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income.

3.2.3 Translation of the net investment in a foreign operation

A monetary item that is receivable from or payable to a foreign operation, for which settlement is neither planned nor likely to occur in the foreseeable future is, in substance, a part of the Bank’s net investment in that foreign operation. The foreign currency difference arising from that monetary item is recognized in other comprehensive income and shall be reclassified to profit or loss on disposal of the net investment.

3.3 Recognition and Measurement of Financial Instruments

3.3.1 Initial recognition

The Bank recognizes a financial asset or a financial liability in its statement of financial position when the Bank becomes party to the contractual provisions of the instrument. A regular way purchase or sale of financial assets (a purchase or sale of a financial asset under a contract whose terms require delivery of the asset within the time frame established generally by regulation or convention in the marketplace concerned) is recognized and derecognized using trade date accounting.

For financial reporting purpose, the Bank classifies (a) financial assets as financial assets at fair value through profit or loss, financial assets at fair value through other comprehensive income, or financial assets at amortized cost and (b) financial liabilities as financial liabilities at fair value through profit or loss, or other financial liabilities. These classifications are based on the business model for managing financial instruments and the contractual cash flow characteristics of the financial instrument at initial recognition.

3.3.2 Subsequent measurement

After initial recognition, financial instruments are measured at amortized cost or fair value based on classification at initial recognition.

3.3.2.1 Amortized cost

3.3.2.2 Fair value

The Bank uses quoted price in an active market which is based on listed market price or dealer price quotations of financial instruments traded in an active market as best estimate of fair value. A financial instrument is regarded as quoted in an active market if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis.

The Bank uses valuation models that are commonly used by market participants and customized for the Bank to determine fair values of common over-the-counter (“OTC”) derivatives such as options, interest rate swaps, and currency swaps which are based on the inputs observable in markets. However, for some complex financial instruments that require fair value measurement by valuation techniques based on certain assumptions because some or all inputs used in the model are not observable in the market, the Bank uses internal valuation models developed from general valuation models or valuation results from independent external valuation institutions.

In addition, the fair value information recognized in the statement of financial position is classified into the following fair value hierarchy, reflecting the significance of the input variables used in the fair value measurement.

Level 1 :	Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Bank can access at the measurement date
Level 2 :	Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly
Level 3 :	Unobservable inputs for the asset or liability

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

If a fair value measurement uses observable inputs that require significant adjustment using unobservable inputs, that measurement is a Level 3 measurement.

The Bank’s Fair Value Evaluation Committee, which consists of the risk management department, trading department and accounting department, reviews the appropriateness of internally developed valuation models, and approves the selection and changing of the external valuation institution and other considerations related to fair value measurement. The results of regular verification of the internally developed valuation models are reported to the Market Risk Management Subcommittee.

The Bank uses a valuation technique which maximizes the use of market inputs and minimizes the use of entity-specific inputs. It incorporates all factors that market participants would consider in pricing the asset or liability and is consistent with economic methodologies applied for pricing financial instruments. Periodically, the Bank calibrates the valuation technique and tests its validity using prices of observable current market transactions of the same instrument or based on other relevant observable market data.

3.3.3 Derecognition

Derecognition is the removal of a previously recognized financial asset or financial liability from the statement of financial position. The derecognition criteria for financial assets and financial liabilities are as follows:

3.3.3.1 Derecognition of financial assets

A financial asset is derecognized when the contractual rights to the cash flows from the financial assets expire or the Bank transfers substantially all the risks and rewards of ownership of the financial asset, or the Bank neither transfers nor retains substantially all the risks and rewards of ownership of the financial asset and the Bank has not retained control. Therefore, if the Bank does not transfer substantially all the risks and rewards of ownership of the financial asset, the Bank continues to recognize the financial asset to the extent of its continuing involvement in the financial asset.

If the Bank transfers the contractual rights to receive the cash flows of the financial asset but retains substantially all the risks and rewards of ownership of the financial asset, the Bank continues to recognize the transferred asset in its entirety and recognize a financial liability for the consideration received.

The Bank writes off a financial asset when the Bank has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. In general, the Bank considers write-off when it is determined that the debtor does not have sufficient funds or income to cover the principal and interest. The write-off decision is made in accordance with internal policy. After the write-off, the Bank can continue to collect the written-off loans according to the internal policy. Recovered amounts from financial assets previously written-off are recognized in profit or loss.

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.3.3.2 Derecognition of financial liabilities

A financial liability is derecognized from the statement of financial position when it is extinguished (i.e., the obligation specified in the contract is discharged, canceled or expires).

3.3.4 Offsetting

A financial asset and a financial liability are offset, and the net amount is presented in the statement of financial position when, and only when, the Bank currently has a legally enforceable right to offset the recognized amounts and intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on a future event and must be legally enforceable in the normal course of business, the event of default, and the event of insolvency or bankruptcy of the Bank and all of the counterparties.

3.4 Cash and Due from Financial Institutions

3.5 Non-derivative Financial Assets

3.5.1 Financial assets at fair value through profit or loss

The Bank may designate certain financial assets upon initial recognition as at fair value through profit or loss when the designation eliminates or significantly reduces a measurement or recognition inconsistency (sometimes referred to as an ‘accounting mismatch’) that would otherwise arise from measuring assets or liabilities or recognizing the gains and losses on them on different bases.

3.5.2 Financial assets at fair value through other comprehensive income

The Bank classifies below financial assets as financial assets at fair value through other comprehensive income:

Debt instruments that are held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and where the assets’ cash flows solely represent payments of principal and interest on the principal amount outstanding and; Equity instruments that are not held for short-term trading but held for strategic investment, and designated as financial assets at fair value through other comprehensive income

3.5.3 Financial assets at amortized cost

3.6 Expected Credit Lossesof Financial Assets (Debt Instruments)

The Bank recognizes loss allowances for expected credit losses at the end of the reporting period for financial assets at amortized cost and fair value through other comprehensive income except for financial assets at fair value through profit or loss.

Expected credit losses are estimated at present value of probability-weighted amount that is determined by evaluating a range of possible outcomes. The Bank measures expected credit losses by reflecting all 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 approaches of measuring expected credit losses in accordance with Korean IFRS are as follows:

•	General approach: for financial assets and unused loan commitments not subject to the below approach<br>
•	Credit-impaired approach: for financial assets that are credit-impaired at the time of acquisition<br>
---	---

Application of general approach is differentiated depending on whether credit risk has increased significantly after initial recognition. If the credit risk on a financial instrument has not increased significantly since initial recognition, the Bank measures loss allowances for that financial instrument at an amount equal to 12-month expected credit losses, whereas if the credit risk on a financial instrument has increased significantly since initial recognition, the Bank measures loss allowances for a financial instrument at an amount equal to the lifetime expected credit losses. Lifetime is the period until the contractual maturity date of financial instruments and means the expected life.

The Bank assesses whether the credit risk has increased significantly using the following criteria, and if one or more of the following criteria are met, it is deemed as significant increase in credit risk. If the contractual cash flows of a financial asset have been renegotiated or modified, the Bank assesses whether the credit risk has increased significantly using the same following criteria.

3.6.1 Forward-looking information

The Bank uses forward-looking information, when determining whether credit risk has increased significantly and measuring expected credit losses.

The Bank assumes that the risk components have a constant correlation with the economic cycle and uses statistical methodologies to estimate the relation between key macroeconomic variables and risk components for the expected credit losses. The Bank has derived a correlation between the time series data of 15 years or more and the key macroeconomic variables and calculates the expected credit losses by reflecting the results of the correlation on the risk component.

The correlation between the major macroeconomic variables and the credit risk are as follows:

Key macroeconomic variables		Correlation between the major macroeconomicvariables and the credit risk
Benchmark interest rate		(+)
AA- rated corporate bond (3-year)		(+)
BBB- rated corporate bond (3-year)		(+)
Composite stock index		(-)
Rate of increase in housing transaction price index (Whole Country)		(-)
Rate of increase in housing transaction price index (Metropolitan Area)		(-)
WTI crude oil price		(+)

Forward-looking information used in the calculation of expected credit losses is based on the macroeconomic forecasts utilized by management of the Bank for its business plan considering reliable external agency’s forecasts and others. The forward-looking information is generated by KB Research with a comprehensive approach to capture the possibility of various economic forecast scenarios that are derived from the internal and external viewpoints of the macroeconomic situation. The Bank determines the macroeconomic variables to be used in forecasting future conditions of the economy, considering the direction of the forecast scenario based on GDP growth and the significant relationship between macroeconomic variables and time series data. Some macroeconomic variables used are different than those used in the previous year.

Notes to the Separate Financial Statements

December31, 2025 and 2024

As of December 31, 2025, the Bank measures expected credit losses by applying both the worse scenario and the crisis scenario, taking into consideration the potential credit risk resulting from the uncertain financial environment locally and globally and the rapid economic recession.

If we assume a probability weight of 100% for each scenario, the impact on expected credit loss allowances and provisions would be as follows.

(In millions of Korean won)
Scenario	Applied probabilityweight	Assumption of 100%		Difference from the bookvalue
Deterioration	80%		1,656,592		(873,402)
Crisis situation	20%		6,036,819		3,506,825

3.6.2 Measuring expected credit losses on financial assets at amortized cost

The expected credit losses of financial assets at amortized cost are measured as present value of the difference between the contractual cash flows to be received and the cash flows expected to be received. The Bank estimates expected future cash flows for financial assets that are individually significant. The Bank selects the individually significant financial assets by comprehensively considering quantitative and qualitative factors (such as debt restructuring or negative net assets, etc.) when the credit risk has increased significantly or the financial asset in credit-impaired (individual assessment of impairment).

For financial assets that are not individually significant, the Bank collectively estimates expected credit losses by grouping loans with a homogeneous credit risk profile (collective assessment of impairment).

3.6.2.1 Individual assessment of impairment

Individual assessment of impairment losses is performed using management’s best estimate on the present value of expected future cash flows. The Bank uses all the available information including financial condition of the borrower such as operating cash flow and net realizable value of any collateral held.

3.6.2.2 Collective assessment of impairment

Collective assessment of impairment losses is performed by using a methodology based on historical loss experience and reflecting forward-looking information. Such a process incorporates factors such as type of collateral, type of product, type of borrower, credit rating, size of portfolio, and recovery period and applies Probability of Default (“PD”) on a group of assets and Loss Given Default (“LGD”) by type of recovery method. Also, the Bank applies certain assumptions to model expected credit losses assessment and to determine input based on loss experience and forward-looking information. These models and assumptions are periodically reviewed to reduce the gap between loss estimate and actual loss experience.

3.6.3 Measuring expected credit losses on financial assets at fair value through other comprehensive income

The Bank measures expected credit losses on financial assets at fair value through other comprehensive income in a manner that is consistent with the requirements that are applicable to financial assets at amortized cost. However, loss allowances are recognized in other comprehensive income. Upon disposal or repayment of financial assets at fair value through other comprehensive income, the amount of loss allowances is reclassified from other comprehensive income to profit or loss.

3.7 Derivative Financial Instruments

The Bank enters into numerous derivative financial instrument contracts such as currency forwards, interest rate swaps, currency swaps, and others for trading purposes or to manage its interest rate risk, currency risk, and others. The Bank’s derivative financial instruments business focuses on addressing the needs of the Bank’s corporate clients to hedge their risk exposure and to hedge the Bank’s risk exposure that results from such client contracts. These derivative financial instruments are presented as derivative financial instruments in the financial statements irrespective of transaction purpose and subsequent measurement requirement.

The Bank designates certain derivative financial instruments as hedging instruments to hedge the risk of changes in fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge) and the risk of changes in cash flow (cash flow hedge).

At the inception of the hedging relationship, there is formal designation and documentation of the hedging relationship and the Bank’s risk management objective and strategy for undertaking the hedge. This documentation includes identification of the hedging instrument, the hedged item, the nature of the risk being hedged, the inception date of hedging relationship and how the Bank will assess the hedging instrument’s effectiveness in offsetting the changes in the hedged item’s fair value or cash flows attributable to the hedged risk.

3.7.1 Derivative financial instruments held for trading

3.7.2 Derivative financial instruments for fair value hedges

If derivative financial instruments are designated and qualify for fair value hedges, changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk are recognized in profit or loss as part of other operating income or expenses. If the hedged items are equity instruments for which the Bank has elected to present changes in fair value in other comprehensive income, changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk are recognized in other comprehensive income.

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.7.3 Derivative financial instruments for cash flow hedges

The effective portion of changes in fair value of derivative financial instruments that are designated and qualify for cash flow hedges is recognized in other comprehensive income, limited to the cumulative change in fair value (present value) of the hedged item (the present value of the cumulative change in the hedged expected future cash flows) from inception of the hedge. The ineffective portion is recognized in profit or loss as other operating income or expenses. The associated gains or losses that were previously recognized in other comprehensive income are reclassified from equity to profit or loss (other operating income or expenses) as a reclassification adjustment in the same period or periods during which the hedged forecast cash flows affect profit or loss. Cash flow hedge accounting is discontinued prospectively if the Bank’s risk management strategy or objective changes, or if the hedging instrument expires, is sold, terminated or exercised, or the hedging relationship ceases to meet the qualifying criteria. When the cash flow hedge accounting is discontinued, the cumulative gains or losses on the hedging instrument that have been recognized in other comprehensive income are reclassified to profit or loss over the period in which the forecast transaction occurs. If the forecast transaction is no longer expected to occur, the cumulative gains or losses that have been recognized in other comprehensive income are immediately reclassified to profit or loss.

3.7.4 Risk management strategy

The Bank hedges the interest rate risk in its entirety. At inception of the hedge relationship, the Bank reviews the hedge effectiveness; and periodically reviews the effectiveness in order to confirm that economic relationship between the hedged item and the hedging instrument exists. The requirement that an economic relationship exists means that the hedging instrument and the hedged item have values that generally move in the opposite direction due to the same risk, which is the hedged risk. The Bank designates the exposure of hedged item opposite to the exposure of hedging instruments in order to meet economic relationship requirement.

The Bank designates the hedge relationship at a one-on-one ratio between the nominal amount of the hedging instrument and the nominal amount of the hedged item.

Hedge ineffectiveness could arise because of differences in the underlying parameters (acquisition date, credit risk or liquidity and others) or other differences between the hedging instrument and the hedged item that the Bank accepts in order to achieve a cost-effective hedging relationship.

The Bank avoids the cash flow variability of its floating rate debt securities by using interest rate swaps. Both are linked to the same interest rate; however, the paid amount of the floating rate may be set on different dates. Even if the variability of interest rate related cash flows (as a risk factor) is designated as a hedged item, the difference in set-up dates creates a hedge ineffectiveness.

The Bank avoids the variability of fair values of its fixed rate debt securities by using interest rate swaps. The method of calculating the number of dates for paying fixed-rate interest can be different between hedging instruments and hedged items. Even if the variability of the fair value due to the benchmark interest rate (as a risk factor) is designated as a hedged item, the difference in the method of calculating the number of the dates creates a hedge ineffectiveness.

3.7.5 Embedded derivatives

3.7.6 Day one gains or losses

If the Bank uses a valuation technique that incorporates unobservable inputs for the fair value of the OTC derivatives at initial recognition, there may be a difference between the transaction price and the amount determined using that valuation technique. In these circumstances, the difference is not recognized in profit or loss but deferred and amortized using the straight-line method over the life of the financial instrument. If the fair value is subsequently determined using observable inputs, the remaining deferred amount is recognized in profit or loss as part of net gains or losses on financial instruments at fair value through profit or loss or other operating income or expenses.

3.8 Property and Equipment

3.8.1 Recognition and measurement

Property and equipment that qualify for recognition as an asset are measured at cost and subsequently carried at its cost less any accumulated depreciation and any accumulated impairment losses.

3.8.2 Depreciation

Land is not depreciated, whereas other property and equipment are depreciated using the method that reflects the pattern in which the asset’s future economic benefits are expected to be consumed by the Bank. The depreciable amount of an asset is determined after deducting its residual value.

Each part of an item of property and equipment with a cost that is significant in relation to the total cost of the item is depreciated separately.

The depreciation method and estimated useful life of property and equipment are as follows:

Property and equipment	Depreciation method	Estimated useful life
Buildings	Straight-line	40 years
Leasehold improvements	Diminishing-balance	4 years
Equipment and vehicles	Diminishing-balance	4 years

Land is not depreciated, whereas other investment properties are depreciated using the method that reflects the pattern in which the asset’s future economic benefits are expected to be consumed by the Bank. The depreciable amount of an asset is determined after deducting its residual value.

The depreciation method and estimated useful life of investment properties are as follows:

Investment properties		Depreciation method		Estimated useful life
Buildings		Straight-line		40 years

3.10 Intangible Assets

Intangible assets are measured initially at cost and subsequently carried at their cost less any accumulated amortization and any accumulated impairment losses.

Intangible assets, except for goodwill and membership rights, are amortized using the straight-line method with no residual value over their estimated useful life since the assets are available for use.

Intangible assets	Amortization method	Estimated useful life
Industrial property rights	Straight-line	5 years
Software	Straight-line	4~5 years
Others	Straight-line	1~13 years

The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at each financial year-end. Where an intangible asset is not being amortized because its useful life is indefinite, the Bank carries out a review in each accounting period to confirm whether events and circumstances still support an indefinite useful life assessment. If they do not, the change in the useful life assessment from indefinite to finite is accounted for as a change in an accounting estimate.

3.10.1 Goodwill

3.10.1.1 Recognition and measurement

Goodwill related to business combinations before January 1, 2010, is stated at its carrying amount, which was recognized under the Bank’s previous accounting policy, prior to the transition to Korean IFRS.

3.10.1.2 Subsequent measurement

Goodwill is not amortized and is stated at cost less accumulated impairment losses. Goodwill that forms part of the carrying amount of an investment in associates and subsidiaries is not separately recognized, and an impairment loss recognized is not allocated to any asset, including goodwill, which forms part of the carrying amount of the investment in the associates.

3.10.2 Subsequent expenditures

3.11 Impairment of Non-financial Assets

The Bank assesses at the end of each reporting period whether there is any indication that a non-financial asset, except for (a) deferred income tax assets, (b) assets arising from employee benefits and (c) non-current assets (or group of assets to be sold) classified as held for sale, may be impaired. If any such indication exists, the Bank estimates the recoverable amount of the asset. However, irrespective of whether there is any indication of impairment, the Bank tests (a) goodwill acquired in a business combination, (b) intangible assets with an indefinite useful life and (c) intangible assets not yet available for use for impairment annually by comparing their carrying amount with their recoverable amount.

The recoverable amount is estimated for the individual asset. If it is not possible to estimate the recoverable amount of the individual asset, the Bank determines the recoverable amount of the cash-generating unit to which the asset belongs. A cash-generating unit is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset is the higher of its fair value less costs of disposal and its value in use. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit that are discounted by a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the future cash flow estimates have not been adjusted.

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

An impairment loss recognized for goodwill is not reversed in a subsequent period. The Bank assesses 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, and an impairment loss recognized in prior periods for an asset other than goodwill shall be reversed if, and only if, there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. The increased carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss cannot exceed the carrying amount that would have been determined (net of amortization or depreciation) had no impairment loss been recognized for the asset in prior years.

3.12 Non-current Assets Held for Sale

A non-current asset is not depreciated (or amortized) while it is classified as held for sale or is part of a disposal group classified as held for sale.

3.13 Financial Liabilities

The Bank classifies financial liabilities into financial liabilities at fair value through profit or loss or other financial liabilities in accordance with the substance of the contractual arrangement and the definitions of financial liabilities. The Bank recognizes financial liabilities in the statement of financial position when the Bank becomes a party to the contractual provisions of the financial liability.

3.13.1 Financial liabilities at fair value through profit or loss

In relation to securities lending or borrowing transactions, when the Bank borrows securities from the Korea Securities Depository and others, these transactions are managed as off-balance sheet items. The borrowed securities are treated as financial liabilities at fair value through profit or loss when they are sold. Changes in fair value at the end of the reporting period and difference between carrying amount at redemption and purchased amount are recognized in profit or loss.

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.13.2 Other financial liabilities

When an asset is sold under repurchase agreement, the Bank continues to recognize the asset with the amount sold being accounted for as borrowings. The Bank derecognizes a financial liability from the statement of financial position only when it is extinguished (i.e., when the obligation specified in the contract is discharged, canceled or expires).

3.14 Provisions

Provisions are recognized when the Bank has a present obligation (legal or constructive) as a result of a past event and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Inevitable risks and uncertainties surrounding related events and circumstances are considered in measuring the best estimate of the provisions, and where the effect of the time value of money is material, the amount of provisions is the present value of the expenditures expected to be required to settle the obligation.

An onerous contract is a contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs under a contract reflect the least net cost of exiting from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfill it. If the Bank has a contract that is onerous, the present obligation under the contract is recognized and measured as provisions.

3.15 Financial Guarantee Contracts

•	The amount initially recognized less, when appropriate, the cumulative amount of income recognized in accordance<br>with Korean IFRS No.1115 Revenue from Contracts with Customers.

3.16 Equity Instrument Issued by the Bank

An equity instrument is any contract or agreement that evidences a residual interest in the assets of an entity after deducting all of its liabilities.

3.16.1 Ordinary shares

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or the exercise of stock option are deducted from the equity, net of any tax effects.

3.16.2 Hybrid securities

The financial instruments can be classified as either financial liabilities or equity in accordance with the terms of the contract. The Bank classifies hybrid securities as an equity if the Bank has the unconditional right to avoid any contractual obligation to deliver cash or another financial asset in relation to the financial instruments.

3.16.3 Compound financial instruments

3.17 Revenue Recognition

The Bank recognizes revenues in accordance with the following steps determined in accordance with Korean IFRS No.1115 Revenue from Contracts withCustomers.

•	Step 1: Identify the contract with a customer.
•	Step 2: Identify the performance obligations in the contract.
---	---
•	Step 3: Determine the transaction price.
---	---
•	Step 4: Allocate the transaction price to the performance obligations in the contract.
---	---
•	Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

3.17.1 Interest income and expense

Interest income and expense on debt securities at fair value through profit or loss (excluding beneficiary certificates, equity investments, and other debt instruments), loans, financial instruments at amortized cost, and debt securities at fair value through other comprehensive income are recognized in the statement of comprehensive income using the effective interest method in accordance with Korean IFRS No.1109 Financial Instruments. The effective interest method is a method of calculating the amortized cost of a financial asset or a financial liability and allocating the interest income or interest expense over the relevant period.

The effective interest rate is the rate that exactly discounts estimated future cash receipts or payments through the expected life of the financial instrument or, where appropriate, a shorter period, to the gross carrying amount of a financial asset or to the amortized cost of a financial liability. When calculating the effective interest rate, the Bank estimates expected cash flows by considering all contractual terms of the financial instrument but does not consider expected credit losses. The calculation includes all fees and points paid (main components of effective interest rate only) or received between parties to the contract that are an integral part of the effective interest rate, transaction costs, and all other premiums or discounts. In those rare cases when it is not possible to reliably estimate the cash flows and the expected life of a financial instrument, the Bank uses the contractual cash flows over the full contractual term of the financial instrument.

3.17.2.2 Fees related to performance obligations satisfied over time

If the control of a good or service is transferred over time, the Bank recognizes revenue related to performance obligations over the period of performance obligations. Fees charged in return for the services for a certain period of time, such as asset management fees, consignment business fees, etc. are recognized over the period of performance obligations.

3.17.2.3 Fees related to performance obligations satisfied at a point in time

Fees earned at a point in time are recognized as revenue when a customer obtains control of a promised good or service and the Bank satisfies a performance obligation.

If the Bank arranges a syndicated loan but does not participate in the syndicated loan or participates in the syndicated loan with the same effective profit as other participants, a syndication arrangement fee is recognized as revenue at the completion of the syndication service.

3.17.3 Net gains or losses on financial instruments at fair value through profit or loss

•	Gains or losses relating to financial instruments at fair value through profit or loss (excluding interest income<br>using the effective interest rate method)
•	Gains or losses relating to derivative financial instruments for trading (including derivative financial<br>instruments for hedging purpose but do not qualify for hedge accounting)

3.18.1 Post-employment benefits

3.18.1.1 Defined contribution plans

When an employee has rendered service to the Bank during a period, the Bank recognizes the contribution payable to a defined contribution plan in exchange for that service as post-employment benefits for the period.

3.18.1.2 Defined benefit plans

3.18.2 Short-term employee benefits

Short-term employee benefits are employee benefits that are expected to be settled wholly before twelve months after the end of the annual reporting period in which the employees render the related service. When an employee has rendered service to the Bank during an accounting period, the Bank recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service as an expense for the period.

The expected cost of profit-sharing and bonus payments is recognized as liabilities when the Bank has a present legal or constructive obligation to make payments as a result of past events, such as service rendered by employees, and a reliable estimate of the obligation can be made.

3.18.3 Share-based payment

The Bank provides its executives and employees with stock grants and mileage stock programs. When stock grants are exercised, the Bank can either select to distribute shares of KB Financial Group Inc., the Parent Company or compensate in cash based on the share price. When mileage stock is exercised, the Bank pays the amount equivalent to share price of KB Financial Group Inc. in cash.

For a share-based payment transaction in which the terms of the arrangement provide the Bank with the choice of whether to settle in cash or by issuing equity instruments, the Bank accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions because the Bank determines that it has a present obligation to settle in cash based on a past practice and a stated policy of settling in cash. Therefore, the Bank measures the liability incurred as consideration for the service received at fair value and recognizes related expense and accrued expense over the vesting periods. For mileage stock, the Bank accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions, which are recognized as expenses and accrued expenses at the time of vesting.

Until the liability is settled, the Bank remeasures the fair value of the liability at the end of each reporting period and at the date of settlement, with any changes in fair value recognized in profit or loss as share-based payments.

3.18.4 Termination benefits

Termination benefits are payable when employment is terminated by the Bank before the normal retirement date, or an employee’s decision to accept an offer of benefits in exchange for the termination of employment. The Bank recognizes a liability and expense for termination benefits at the earlier of the following dates; when the Bank can no longer withdraw the offer of those benefits and when the Bank recognizes costs for a restructuring that is within the scope of Korean IFRS No.1037 and involves the payment of termination benefits. If the termination benefits are not expected to be settled wholly before twelve months after the end of the annual reporting period, then the termination benefits are discounted to present value.

3.19 Income Tax Expense

3.19.1 Current income tax

The Bank offsets current income tax assets and current income tax liabilities if, and only if, the Bank (a) has a legally enforceable right to offset the recognized amounts and (b) intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.19.2 Deferred income tax

The carrying amount of a deferred income tax asset is reviewed at the end of each reporting period. The Bank reduces the carrying amount of a deferred income tax asset to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred income tax asset to be utilized.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred income tax liabilities and deferred income tax assets reflects the tax consequences that would follow from the manner in which the Bank expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

The Bank offsets deferred income tax assets and deferred income tax liabilities if, and only if the Bank has a legally enforceable right to offset current income tax assets against current income tax liabilities and the deferred income tax assets and the deferred income tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current income tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred income tax liabilities or assets are expected to be settled or recovered.

3.19.3 Uncertain tax positions

Uncertain tax positions arise from tax treatments applied by the Bank which may be challenged by the tax authorities due to the complexity of the transaction or different interpretation of the tax laws, such as a claim for rectification, a claim for a refund related to additional tax or a tax investigation by the tax authorities. The Bank recognizes its uncertain tax positions in the financial statements in accordance with Korean IFRS No.1012 and Interpretation of Korean IFRS No.2123. The income tax asset is recognized if a tax refund is probable for taxes levied by the tax authority, and the amount to be paid as a result of the tax investigation and others is recognized as the current tax payable. However, penalty tax and additional refund on tax are regarded as penalty or interest and are accounted for in accordance with Korean IFRS No.1037.

3.19.4 Global Minimum Tax

The Bank is subject to the global minimum tax under Pillar 2 legislation and has applied the exemption from recognizing and disclosing related deferred tax.

3.20 Transactions with the Trust Accounts

The Bank accounts for trust assets separately from its own assets in accordance with the Financial Investment Services and Capital Markets Act. The borrowings from trust accounts represent transfer of funds in trust accounts into banking accounts. Such borrowings from trust accounts are recorded as receivables from the banking accounts in the trust accounts and as borrowings from trust accounts in the banking accounts. The Bank earns trust fees from the trust accounts for its management of trust assets and operations. The reserves for future profits and losses are set up in the trust accounts for profits and losses related to those trust funds with a guarantee of the principal or of the principal and a certain minimum rate of return in accordance with the relevant laws and regulations applicable to trust operations. The reserves are used to provide for the losses on such trust funds and, if the losses incurred are in excess of the reserves, the excess losses are compensation paid as a loss on trust management in other operating expenses and the trust accounts recognize the corresponding compensation as compensation from banking accounts.

3.21 Leases

The Bank as a lessor recognizes lease payments from operating leases as income on a straight-line basis over the lease term. Initial direct costs incurred in obtaining an operating lease are added to the carrying amount of the underlying asset and recognized as expense over the lease term on the same basis as lease income. The respective leased assets are included in the statement of financial position based on their nature.

Lease liabilities include the net present value of the following lease payments:

•	Fixed payments (including in-substance fixed payments), less any lease<br>incentives receivable
•	Variable lease payments that depend on an index or a rate
---	---
•	Amounts expected to be payable by the lessee under residual value guarantees
---	---
•	The exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and<br>
---	---
•	Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to<br>terminate the lease
---	---

Right-of-use assets are measured at cost comprising the following:

•	The amount of the initial measurement of the lease liability
•	Any lease payments made at or before the commencement date, less any lease incentives received<br>
---	---
•	Any initial direct costs incurred by the lessee, and
---	---
•	An estimate of restoration costs
---	---

However, the Bank can elect not to apply the requirements of Korean IFRS No.1116 to short-term lease (lease that, at the commencement date, has a lease term of 12 months or less) and leases for which the underlying asset is of low value (for example, underlying leased asset under USD 5,000). The Bank applies the exemption of the standard for one time lease of real estate (for training purpose) and leases of low-value assets (underlying assets less than ~~W~~ 5 million or USD 5,000).

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December31, 2025 and 2024

The right-of-use asset is depreciated from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term.

For sale and leaseback transactions, the Bank applies the requirements of Korean IFRS No.1115 Revenue from Contracts with Customers, to determine whether the transfer of an asset is accounted for as a sale of that asset.

3.22 Operating Segments

The Bank identifies its operating segments based on internal reports which are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance. Segment information includes items which are directly attributable and can be allocated to the segment on a reasonable basis.

4. Financial Risk Management

4.1 Summary

4.1.1 Overview of financial risk management policy

The financial risks that the Bank is exposed to are credit risk, market risk, liquidity risk, operational risk, and others.

This note regarding financial risk management provides information about the risks that the Bank is exposed to and about its objectives, policies, risk assessment and management procedures, and capital management. Additional quantitative information is disclosed throughout the separate financial statements.

The Bank’s risk management system focuses on efficiently supporting long-term strategy and management decisions of each business group through increased risk transparency, spread of risk management culture, prevention of risk transfer between risk types, and preemptive response to rapidly changing financial environments. Credit risk, market risk, liquidity risk, and operational risk are recognized as the Bank’s significant risks and measured and managed by quantifying them in the form of internal capital or Value at Risk (“VaR”) using statistical methods.

4.1.2 Risk management organization

4.1.2.1 Risk Management Committee

4.1.2.2 Risk Management Council

The Risk Management Council deliberates on and resolves matters delegated by the Risk Management Committee and discusses the details of risk management policies and procedures of the Bank.

4.1.2.3 Risk Management Subcommittees

The Risk Management Subcommittee implements decisions made by the Risk Management Council and makes practical decisions regarding the implementation of risk management policies and procedures.

•	Credit Risk Management Subcommittee

4.1.2.4 Risk Management Group

The Risk Management Group manages detailed risk management policies, procedures, and business processes.

4.2 Credit Risk

4.2.1 Overview of credit risk

Credit risk is the risk of loss from the portfolio of assets held due to the counterparty’s default, breach of contract, and deterioration of credit quality. For risk management reporting purposes, the Bank considers all factors of credit risk exposure, such as default risk of individual borrowers, country risk, and risk of specific sectors. The Bank defines default as the definition applied to the calculation of Capital Adequacy Ratio under the new Basel Accord (Basel III).

4.2.2 Credit risk management

The Bank measures the expected loss and internal capital for the assets subject to credit risk management, including on-balance and off-balance sheet assets, and uses them as management indicators. The Bank allocates and manages credit risk internal capital limits.

In addition, to prevent excessive concentration of exposures by borrower and industry, the total exposure limit at the Bank level is introduced, applied, and managed to control the credit concentration risk.

All of the Bank’s loan customers (individuals and corporates) are assigned a credit rating and managed by a credit evaluation system. For individuals, the credit rating is evaluated by utilizing personal information, income and job information, asset information, and bank transaction information. For corporates, the credit rating is evaluated by analyzing and utilizing financial and non-financial information which measures current and future corporate value and ability to repay the debt. Also, the extent to which corporates have the ability to meet debt obligations is comprehensively considered.

The credit rating, once assigned, serves as the fundamental instrument in the Bank’s credit risk management, and is applied in a wide range of credit risk management processes, including credit approval, credit limit management, loan pricing, and assessment of allowances for credit losses. For corporates, the Bank conducts a regular credit evaluation at least once a year, and the review and supervision departments regularly validate the adequacy of credit ratings to manage credit risks.

In order to establish a credit risk management system, the Bank manages credit risk by forming a separate risk management organization. In particular, independently of the Sales Group, the Credit Management & Analysis Group, Retail Customer Group and SME/SOHO Customer Group are in charge of loan policy, loan system, credit rating, credit analysis, follow-up management, and corporate restructuring. The Risk Management Group is responsible for establishing policies on credit risk management, measuring and limiting internal capital of credit risk, setting credit limits, credit review, and verification of credit rating models.

4.2.4 Credit risk of loans

The Bank maintains allowances for loan losses associated with credit risk of loans to manage its credit risk.

The Bank assesses expected credit losses and recognizes loss allowances of financial assets at amortized cost and financial assets at fair value through other comprehensive income (debt instruments). Financial assets at fair value through profit or loss are excluded. Expected credit losses are a probability-weighted estimate of possible credit losses occurring in a certain range by reflecting reasonable and supportable information that is reasonably available at the end of the reporting period without undue cost or effort, including information about past events, current conditions, and forecasts of future economic conditions. The Bank measures the expected credit losses of loans classified as financial assets at amortized cost by deducting allowances for credit losses in the statements of financial position. The expected credit losses of loans classified as financial assets at fair value through other comprehensive income are presented in other comprehensive income in the statements of financial position.

4.3 Liquidity Risk

4.3.1 Overview of liquidity risk

Liquidity risk is a risk that the Bank becomes insolvent due to the mismatch between the inflow and outflow of funds, unexpected cash outflows, or a risk of loss due to financing funds at a high interest rate or disposing of securities at an unfavorable price due to lack of available funds. The Bank manages its liquidity risk through analysis of the contractual maturity of interest-bearing assets and liabilities, assets and liabilities related to the other inflows and outflows of funds, and off-balance sheet items related to the inflows and outflows of funds such as currency derivative instruments and others.

4.3.2 Liquidity risk management and indicator

The Bank establishes a liquidity risk management strategy, including objectives of liquidity risk management, management policies, and internal control systems, and obtains an approval from the Risk Management Committee. The Risk Management Committee establishes the Risk Management Council for efficient risk management to supervise the establishment and implementation of policies according to risk management strategies.

The Bank calculates and manages the Liquidity Coverage Ratio (“LCR”), Net Stable Funding Ratio (“NSFR”), liquidity ratio, maturity mismatch ratio and liquidity stress testing results for all transactions and off-balance sheet transactions, that affect the cash flows in Korean won and foreign currency funds raised and operated for the management of liquidity risks and periodically reports them to the Risk Management Council and the Risk Management Committee.

4.3.3 Analysis of remaining contractual maturity of financial liabilities

The cash flows disclosed in the maturity analysis are undiscounted contractual amounts including principal and future interest payments; as such, amounts in the table below do not match with those in the statements of financial position which are based on discounted cash flows. The future interest payments of floating-rate liabilities are calculated on the assumption that the current interest rate is the same until maturity.

4.4 Market Risk

4.4.1 Concept

Market risk refers to risks that can result in losses due to changes in market factors such as interest rate, stock price, and foreign exchange rate, etc., which arise from securities, derivatives, and others. The most significant risks associated with trading positions are interest rate risk, currency risk, and additional risks including stock price risk. The non-trading position is also exposed to interest rate risk. The Bank manages the market risks by dividing them into those arising from the trading position and those arising from the non-trading position.

4.4.2 Risk management

The Bank sets and monitors internal capital limits for market risk and interest rate risk to manage the risks of trading and non-trading positions. In order to manage market risk efficiently, the Bank maintains risk management systems and procedures such as trading policies and procedures, market risk management guidelines for trading positions, and ALM risk management guidelines for non-trading positions. The entire process is carried out through the approval by the Risk Management Council and the Risk Management Committee of the Bank.

The Bank’s Risk Management Council establishes and enforces overall market risk management policies for market risk management and decides to establish position limits, loss limits, VaR limits, and approves non-standard new products. In addition, the Market Risk Management Subcommittee, chaired by Chief Risk Officer (“CRO”), is a practical decision-making body for market risk management and determines position limits, loss limits, VaR limits, sensitivity limits, and scenario loss limits for each department of the business group.

4.4.2 Risk management (cont’d)

The Asset-Liability Management Committee (“ALCO”) determines interest rate and commission operating standards and ALM operation policies and enacts and revises relevant guidelines. The Risk Management Council monitors the establishment and enforcement of ALM risk management policies and enacts and revises ALM risk management guidelines. Interest rate risk limits are set based on future asset and liability positions and expected interest rate volatility, which reflect annual business plans. The Treasury Department and the Risk Management Department regularly measure and monitor interest rate risk and report the status and limit of interest rate risk including changes in Economic Value of Equity (“△EVE”), changes in Net Interest Income (“△NII”), and duration gap to the ALCO and the Risk Management Council on a monthly basis, and to the Risk Management Committee on a quarterly basis. To ensure the adequacy of interest rate risk and liquidity risk management, the Risk Management Department assigns the limits, monitors and reviews the procedures and tasks of ALM operations conducted by the Treasury department, and reports related matters to the management independently.

4.4.3 Trading position

4.4.3.1 Definition of a trading position

The trading position, which is subject to market risk management, includes interest rate position and stock position held for short-term trading profit. The Bank also includes and manages all foreign currency positions in our trading positions. The trading position subject to market risk management is the trading position defined in “Trading Policy and Guidelines” and the basic requirements for the trading position are as follows:

•	The target position has no restrictions on the sale, the daily fair value assessment should be made, and the<br>embedded significant risk can be hedged in the market.
•	The trading position classification criteria should be clearly defined in the Trading Policy and Guidelines, and<br>the trading position should be managed by a separate trading department.
---	---
•	The target position must be operated according to the documented trading strategy, and the management of position<br>limit must be carried out.
---	---
•	The specialized dealer or operating department shall have the authority to execute the transaction without prior<br>approval from the Risk Management Department, etc. within the predetermined limits of the target position.
---	---
•	The target positions should be periodically reported to management for risk management of the Bank.<br>
---	---

4.4.3.2 Methods of observing market risk arising from trading positions

Banks are now required to calculate regulatory capital for all trading positions using the standard method through market risk management systems, following the adoption of Basel III market risk standard approach regulation in 2023.

Furthermore, risk control and management for derivative financial product transactions are conducted in accordance with regulations and guidelines set by the Financial Supervisory Service.

4.4.3.3 Standard Method

Market risk regulatory capital is calculated using the Basel III standard method as follows.

[ Market risk regulatory capital = (a)Sensitivity-based risk + (b)Default risk + (c)Residual risk ]

•	Sensitivity-based risk, which forms the basis of the Basel III standard method for market risk, involves<br>calculating the expected losses for each risk factor by applying and aggregating the risk weights and correlation coefficients specified by the Basel Committee.
•	Default risk is the risk that arises from the issuer default of securities and derivatives that are not<br>considered in sensitivity-based risk. It is calculated by applying risk weights based on the issuer’s credit rating and other factors.
---	---
•	Residual risk is the risk that is not considered by sensitivity-based and default risk calculations. It is<br>calculated by applying a certain percentage determined by the Basel Committee to the nominal value of structured products and other non-standard underlying assets.
---	---
						Description
---	---	---	---	---	---	---
Sensitivity-based risk		Interest rate risk group		GIRR		The risk associated with risk-free interest rates (typically OIS rates) defined by currency and maturity.
				CSR		The risk associated with the issuer’s interest rate credit spread, defined by creditworthiness and sector.
		Equity risk group				The risk factors associated with equity, defined by market capitalization, economic conditions, and sector
		Foreign exchange risk group				The risk factors associated with exchange rate, defined by currency pairs
		Commodity risk group				The risk factors associated with commodities, defined by commodity types.
Default risk						Issuer default risk in securities (bonds, etc.) and derivatives.
Residual risk						Additional risks imposed on non-standard underlying asset products, etc.

The table below represents regulatory capital for sensitivity-based risk, default risk, and residual risk of trading positions of December 31, 2025 and 2024, are as follows:

(In millions of Korean won)
Sensitivity-based risk	GIRR(General interest rate)	51,788	65,112
	CSR(non-securitization)	92,808	71,343
	Equity risk	150	2,656
	Foreign exchange risk	152,108	158,770
	Commodity risk	25	15

4.4.3.3.1 Interest Rate RiskInterest rate risk in trading positions mainly arises from debt securities denominated in Korean won. The Bank’s trading strategy is to generate short-term trading gains from fluctuations in interest rates. Interest rate risk related to the major trading portfolio is managed using sensitivity analysis (Price Value of a Basis Point: PVBP).

4.4.3.3.2 Stock Price RiskStock price risk mainly arises from stock spot positions held by principal-guaranteed trusts and stock-related derivative positions held by the market trading division. Such stock price risk is managed through sensitivity limits and other risk control measures.

4.4.3.3.3 Currency RiskForeign exchange risk arises from holding assets, liabilities, and currency-related derivatives denominated in foreign currencies other than Korean won. The majority of the net open foreign currency exposure arises in U.S. dollars and Indonesian rupiah. Such foreign exchange risk is managed through limits on net open foreign currency exposures and other internal control mechanisms.

4.4.4 Non-trading position (Interest Rate Risk of Banking Book (“IRRBB”))

4.4.4.1 Definition of IRRBB

IRRBB is a change in equity and earnings due to the changes in value of interest-sensitive assets and liabilities, etc., and is measured by △EVE and △NII.

4.4.4.2 The Bank’s overall interest rate risk management and mitigation strategy

The Risk Management Committee approves policies, procedures and limits for managing interest rate risk, and the management department regularly reports on interest rate risk levels of △EVE and △NII against the set limit, changes in market conditions, and others. In order to measure the sensitivity of the economic value and earnings to changes in interest rates, the Bank calculates monthly interest rate gap and duration gap for assets and liabilities. In addition, the management department conducts an interest rate risk crisis analysis at least once a quarter assuming abnormal interest rate fluctuations and reports the results to the Risk Management Council. Independent internal and external audit department regularly check the process of identifying, measuring and monitoring interest rate risk. The interest rate risk model adequacy test is carried out regularly at least once a year by the verification department independent of the management department.

4.4.4.3 Main modeling assumption used for the Bank’s interest rate risk measurement system for internal management

The bank measures adverse fluctuations in economic value resulting from changes in interest rates following the interest rate risk calculation standards set by the Financial Supervisory Service.

Notes to the Separate Financial Statements

4.4.4.5 Main assumptions used for calculating **△**EVE , **△**NII

The Bank calculates interest rate risk, including all cash flow of interest-sensitive assets and liabilities, and off-balance sheet items in the banking book. △EVE assumes a run-off balance sheet where the existing bank account positions are amortized and not replaced by new businesses. In addition, the contractual interest rate, including commercial margins and other spread components, is applied to generate cash flows. When discounting cash flows, △EVE is calculated by applying risk-free interest rate that do not include commercial margins and other spread components.

△NII assumes a constant balance sheet where maturing or repricing cash flows during the target management period are replaced by new cash flows with identical features. The interest rate risk is calculated for the interest rate shock scenario by adding up only if the risk is a loss for each currency. After classifying into retail/transactional, retail/non-transactional, and wholesale according to customers and regular transactions, the average repricing maturity of non-maturity deposits is determined by taking into account the proportion of core deposits and cap on average maturity of core deposits for each category. The average repricing maturity of non-maturity deposits is 2.5 years for core deposits, 1 day for non-core deposits, and the longest repricing maturity is five years. The prepayment rate of fixed rate loans and term deposit redemption ratio are estimated by dividing the amount of prepayment amount and redemption amount during the previous month by the balance at the end of the previous month, respectively.

4.4.4.6 △EVE and △NII

The Bank calculates △EVE by applying six interest rate shock and stress scenarios, and △NII is calculated by applying parallel shock up and parallel shock down scenarios. Results as of December 31, 2025 and 2024, are as follows:

(In millions of Korean won)	December 31, 2025				December 31, 2024
	ΔEVE		ΔNII		ΔEVE		ΔNII
Scenario 1 (Parallel shock up)		644,705		219,251		482,105		158,187
Scenario 2 (Parallel shock down)		116,880		80,054		170,764		30,845
Scenario 3 (Short rates down and long rates up)		338,699				226,086
Scenario 4 (Short rates up and long rates down)		313,737				437,728
Scenario 5 (Short rates shock up)		588,522				532,380
Scenario 6 (Short rates shock down)		386,330				330,968

4.5 Operational Risk

4.5.1 Concept

The Bank defines operational risk as loss risk arising from improper or incorrect internal procedures, personnel, systems or external events and includes financial and non-financial risks.

4.5.2 Risk management

The purpose of operational risk management is not only to comply with supervisory and regulatory requirements, but also to spread risk management culture, strengthen internal control, improve processes, and provide timely feedback to management and all employees. The Bank established a Business Continuity Planning (BCP) to carry out continuous work in emergency situations and established alternative facilities. The Bank conducts simulation training for headquarters and IT departments to check the business continuity framework.

4.6 Capital Management

The Bank complies with the capital adequacy standard established by the financial supervisory authority. This capital adequacy standard is based on Basel III revised by Basel Committee on Banking Supervision in Bank for International Settlements (“BIS”) in June 2011 and was implemented in Korea in December 2013.

According to this standard, the Bank is required to maintain a minimum capital adequacy ratio to risk-weighted assets (Common Equity Tier 1 Capital ratio of 4.5%, Tier 1 Capital ratio of 6.0%, and Total Capital ratio of 8.0%) as of December 31, 2025. In addition, a Capital Conservation Buffer of 2.5%, a Countercyclical Capital Buffer of 1.0%, and Capital Requirement for Domestic Systemically Important Banks (D-SIB) of 1.0% are applied. Therefore, the Bank is required to maintain a capital adequacy ratio, including the minimum capital adequacy ratio and additional capital requirements (Common Equity Tier 1 Capital ratio of 9.0%, Tier 1 Capital ratio of 10.5%, and Total Capital ratio of 12.5%

The Bank’s capital is classified into three categories in accordance with the Detailed Regulations on Supervision of Banking Business as follows:

•	Common Equity Tier 1 Capital: Common equity Tier 1 Capital is the first to take losses of the Bank and is the<br>last to be compensated in liquidation of the Bank and not repaid except for liquidation. It includes capital, capital surplus, retained earnings, non-controlling interests of the consolidated subsidiaries,<br>accumulated other comprehensive income, and other capital surplus, etc.
•	Additional Tier 1 Capital: Additional Tier 1 Capital includes capital, capital surplus, etc. related to the<br>issuance of capital securities of a permanent nature that meet the conditional capital securities requirements.
---	---
•	Tier 2 Capital: Tier 2 Capital means capital that can compensate for losses of the Bank upon liquidation,<br>including (a) the amount of subordinated bonds with maturity of not less than 5 years that meet the conditional capital securities requirements, and (b) the allowances for credit losses accumulated on the loans which are classified as<br>normal or precautionary in accordance with Regulations on Supervision of Banking Business, and others.

4.6 Capital Management (cont’d)

The risk-weighted assets are the magnitude of assets that reflect the risk that the Bank has to bear, including risks inherent in all assets, errors in the operation of internal processes, and risk of loss that may arise from external events. The Bank calculates risk-weighted assets by each risk (credit risk, market risk, and operational risk) based on the Detailed Regulations on Supervision of Banking Business and uses them to calculate capital adequacy ratio. The Bank complied with external capital adequacy requirements as of December 31, 2025 and 2024.

Apart from the capital adequacy ratio, the Bank evaluates and manages capital adequacy through internal policies. The evaluation of capital adequacy compares the size of available capital (the amount of capital actually available) to the size of internal capital (the amount of capital required to cover all the significant risks faced by the Bank under its target credit rating), which monitors financial soundness and provides a risk-adjusted performance measurement basis. The internal capital for capital adequacy assessment is calculated by adding the results of a stress test and other additional capital requirements to the internal capital calculated for each individual risk.

The Risk Management Committee of the Bank determines the risk appetite of the Bank, allocates internal capital by risk type and business group, and each business group operates capital efficiently within the range of the allocated internal capital. The Risk Management Department of the Bank monitors internal capital limit management and reports it to management and the Risk Management Committee. If the limit of internal capital is expected to be exceeded, the Bank’s capital adequacy management is carried out through review and approval by the Risk Management Committee in advance.

Details of the Bank’s capital adequacy ratio in accordance with Basel III requirements as of December 31, 2025 and 2024, are as follows:

(In millions of Korean won)
Total Capital:		41,604,455	40,573,940
Tier 1 Capital		36,960,176	35,059,009

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. The Bank discloses the fair value of each class of assets and liabilities in a way that permits it to be compared with its carrying amount at the end of each reporting period. The best evidence of fair value of financial instruments is a quoted price in an active market.

Notes to the Separate Financial Statements

December31, 2025 and 2024

Methods of determining fair value of financial instruments are as follows:

Cash and due from financial institutions		Fair value of cash is the same as its carrying amount. Carrying amount of demand deposits and settlement deposits is a reasonable approximation of fair value because these financial instruments do not have a fixed maturity and are<br>receivable on demand. Fair value of general deposits is measured using a Discounted Cash Flow (“DCF”) Model.
Securities<br><br><br>due from financial institutions and deposits indexed to gold price		Fair value of securities and others that are traded in an active market and due from financial institutions and deposits indexed to the gold price is determined using the quoted prices. If there is no quoted price, fair value is<br>determined using external professional valuation institutions. The institutions use one or more valuation techniques that are deemed appropriate considering the characteristics of the financial instruments including a DCF Model, MonteCarlo<br>Simulation, Free Cash Flow to Equity Model, Comparable Company Analysis, Dividend Discount Model and Net Asset Value Method.
Loans		Fair value of loans is determined using a DCF Model and independent external professional valuation institutions. Fair value measured by using a DCF Model is determined by discounting the expected cash flows, which are contractual<br>cash flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Derivatives		Fair value of exchange traded derivatives is determined using quoted prices in an active market, and fair value of OTC derivatives is determined using valuation techniques. The Bank uses internally developed valuation models that<br>are widely used by market participants to determine the fair value of plain vanilla OTC derivatives including options, interest rate swaps, and currency swaps, based on observable market parameters. However, some complex financial instruments are<br>valued using appropriate models developed from generally accepted market valuation models including a Finite Difference Method (“FDM”), MonteCarlo Simulation, and Tree Model or valuation results from independent external professional<br>valuation institutions. For OTC derivatives, the credit risk of the counterparty and the Bank’s own credit risk are applied through a credit valuation adjustment method.
Deposits		Carrying amount of demand deposits is a reasonable approximation of fair value because they do not have a fixed maturity and are payable on demand. Fair value of time deposits is determined using a DCF Model discounting the expected<br>cash flows, which are contractual cash flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Borrowings		Carrying amount of overdrafts in foreign currency is a reasonable approximation of fair value because they do not have a fixed maturity and are payable on demand. Fair value of other borrowings is determined using a DCF<br>Model.
Debentures		Fair value is determined using valuation results (DCF Model) of external professional valuation institutions, which are calculated using market inputs.
Other financial assets and other financial liabilities		Carrying amount is a reasonable approximation of fair value because other financial assets and other financial liabilities are temporary accounts used for other various transactions, and their maturities are relatively short or not<br>defined.

6.1.2 Fair value hierarchy

The Bank believes that valuation techniques used for measuring the fair value of financial instruments are reasonable and that the fair value recognized in the statement of financial position is appropriate. However, the fair value of the financial instruments recognized in the statement of financial position may be different if other valuation techniques or assumptions are used. Additionally, as there are a variety of valuation techniques and assumptions used in measuring fair value, it may be difficult to reasonably compare the fair value with that of other financial institutions.

The Bank classifies and discloses fair value of the financial instruments into the three fair value levels as follows:

Level 1:	The fair values are based on quoted prices (unadjusted) in active markets for identical assets or liabilities<br>that the entity can access at the measurement date.
Level 2:	The fair values are based on inputs other than quoted prices included within Level 1 that are observable<br>for the asset or liability, either directly or indirectly.
---	---
Level 3:	The fair values are based on unobservable inputs for the asset or liability.

6.2 Disclosure of Fair Value Hierarchy Level 3

6.2.1 Valuation policy and process of Level 3 fair value

The Bank uses an external, independent and qualified valuation service or internal valuation models to determine the fair value of financial instruments at the end of every reporting period.

If the changes in situations or events cause transfers between the fair value hierarchy level for a financial asset or liability occur, the Bank’s policy is to recognize such transfers as having occurred at the beginning of the reporting period.

^1^	For derivative financial instruments, changes in fair value are calculated by shifting principal unobservable<br>input parameters such as price and the volatility of underlying asset by ± 10%.
---	---
2	For equity securities, changes in fair value are calculated by shifting principal unobservable input parameters<br>such as liquidation value (-1%p~1%p), discount rate (-1%p~1%p) and growth rate (0%p~1%p).
---	---
^3^	For beneficiary certificates, it is practically impossible to analyze sensitivity of changes in unobservable<br>inputs. However, for beneficiary certificates whose underlying assets are real estates, changes in fair value are calculated by shifting the rate of real estate sale price fluctuation (-1%p~1%p). There is no<br>significant correlation among major unobservable inputs.

^4^	For loans, changes in fair value are calculated by shifting principal unobservable input parameters such as the<br>discount rate (-1%p~1%p).

6.2.4 Day one gains or losses

When the Bank measures the fair value of OTC derivatives using inputs that are not based on observable market data, there could be a difference between the transaction price and the amount determined using that valuation technique. In these circumstances, the fair value of financial instruments is recognized as the transaction price, and the difference is not recognized in profit or loss but deferred and amortized using the straight-line method over the life of the financial instrument. When the fair value of the financial instruments is subsequently determined using observable market inputs, the remaining deferred amount is recognized in profit or loss. There is no deferred day one gains or losses for the years ended December 31, 2025 and 2024.

6.4.2 Bonds sold under repurchase agreements and loaned securities

The Bank continues to recognize the financial assets related to bonds sold under repurchase agreements and securities lending transactions in the statement of financial position since those transactions are not qualified for derecognition even though the Bank transfers the financial assets. Bonds sold under repurchase agreements are sold on the condition that they will be repurchased at a fixed price, and loaned securities will be returned at the expiration of the loan period. Thus, the Bank retains substantially all the risks and rewards of ownership of the financial assets.

The carrying amount of transferred assets and related liabilities as of December 31, 2025 and 2024, are as follows:

(In millions of Korean won)		December 31, 2025

6.5 Offsetting Financial Assets and Financial Liabilities

The Bank enters into International Swaps and Derivatives Association (“ISDA”) master netting agreements and other similar arrangements with the Bank’s OTC derivative and spot exchange counterparties. Similar netting agreements are also entered into with the Bank’s (a) sales or purchases of bonds under repurchase agreements and (b) securities lending and borrowing transactions, etc. Pursuant to these agreements, in the event of default by one party, contracts are to be terminated and receivables and payables are to be offset. As the Bank has the legal right of offset and settles in net amount, domestic exchange settlement debits and domestic exchange settlement credits are recognized in its net settlement balance in the statement of financial position. Other financial instruments such as account receivables and account payables related to listed securities, and derivatives or OTC derivatives settled by the central clearing house are also recognized in its net settlement balance in the statement of financial position as the Bank has the legal right of offset and settles in net amount.

6.5.1 Details of financial assets subject to enforceable master netting agreements or similar arrangements as of December 31, 2025 and 2024, are as follows:

9. Derivative Financial Instruments and Hedge Accounting

The Bank engages in derivative transactions to hedge interest rate and currency risks arising from its assets and liabilities. In particular, the Bank applies fair value hedge accounting using interest rate swaps and interest rate futures to hedge the risk of changes in fair value due to the changes in interest rate of debentures, deposits, and debt securities at fair value through other comprehensive income. Also, the Bank applies cash flow hedge accounting using interest rate swaps to hedge the risk of changes in cash flows of debentures in foreign currencies, and borrowings in foreign currencies.

The fair value less costs of disposal is the amount obtainable from the disposal in an arm’s length transaction between knowledgeable, willing parties, after deducting the costs of disposal. If it is difficult to measure the amount obtainable from the disposal of the cash-generating unit, the disposal amount of a similar cash-generating unit in the past transaction is used by reflecting the characteristics of the cash-generating unit to be measured. If it is not possible to obtain reliable information to measure the fair value less costs of disposal, the Bank uses the asset’s value in use as its recoverable amount. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit. The future cash flows of retail banking and corporate banking are estimated on the assumption that the future cash flows will increase by 1.0% per year. The key assumptions used for the estimation of the future cash flows are based on GDP growth rate, market size, and the Bank’s market share. The discount rate is a pre-tax rate that reflects assumptions regarding risk-free interest rate, market risk premium, and the risks specific to the cash-generating unit.

23. Net Defined Benefit Liabilities (Assets)

23.1 Defined Benefit Plan

The Bank operates defined benefit plans which have the following characteristics:

The Bank has the obligation to pay the agreed benefits to all its current and former employees.
The Bank assumes actuarial risk (that benefits will cost more than expected) and investment risk.

The net defined benefit liabilities (assets) recognized in the statements of financial position are calculated in accordance with an actuarial valuation method using assumptions based on market data and historical data such as discount rate, future salary increase rate, and mortality. Actuarial assumptions may differ from actual results due to changes in the market conditions, economic trends, and mortality trends.

37.6.1 The Bank has 31 pending lawsuits as a plaintiff (excluding simple lawsuits related to the collection or management of loans), with aggregate claims amount of ~~W~~ 128,301 million, and has 154 pending lawsuits as a defendant (excluding simple lawsuits related to the collection or management of loans), with aggregate claims amount of ~~W~~ 438,226 million. Details of pending lawsuits in which the Bank is a defendant as of December 31, 2025, are as follows:

(In number of cases, in millions of Koreanwon)

Lawsuits		Amount			Description of the lawsuits		Status of the lawsuits
Request for return of redemption amount			60,281		The Bank invested the assets entrusted by OO Asset Management and OO Investment Trust Management in the Fairfield Sentry Limited (the<br>Fairfield Sentry Limited reinvested the assets in Bernard L. Madoff Investment Securities LLC managed by Bernard Madoff) and subsequently redeemed them and returned the proceeds to the beneficiaries. Following the occurrence of Ponzi scheme-related<br>losses, Bernard L. Madoff Investment Securities LLC is undergoing a liquidation process.<br> <br>The bankruptcy trustee of Bernard L. Madoff Investment Securities<br>LLC filed a lawsuit against the Bank, seeking the return of the redemption proceeds received by the Bank through Fairfield Sentry Limited.		Application for dismissal by the defendant has been denied, and further proceedings are scheduled. [Related litigation is in progress at the<br>New York Southern District Federal Bankruptcy Court (10-3777) at the written complaint review stage]<br> <br>The financial<br>impact on the bank is not significant due to the possibility of winning the case.
Return of unjust enrichment			156,755		MTS Bank, which was transacting through correspondent accounts with the Bank, was listed on the OFAC (Office of Foreign Assets Control of the<br>U.S. Department of the Treasury) SDN (Specially Designated Nationals) List. Consequently, the Bank has frozen the foreign currency accounts held under the name of MTS Bank.<br><br><br>Subsequently, MTS Bank filed a lawsuit with the Moscow City Commercial Court seeking the restitution of account balances.		Responding to local court trial schedule (Following the first-instance judgment against the bank on December 2, 2025, currently<br>responding in the appellate proceedings)<br> <br><br> <br>Due to compliance with U.S. OFAC<br>regulations, it is difficult to easily predict the likelihood of winning the lawsuit proceeding in the Russian court.<br> <br>However, the claim amount can be<br>covered by the balance in the plaintiff’s account, and the bank is expected to experience a financial impact equivalent to the delayed interest.

Report on Independent Auditor’s

Review of Internal Control over Financial Reporting

(English Translation of a Report Originally Issued in Korean)

To the Board of Directors and Shareholders of

Kookmin Bank

We have reviewed the accompanying management’s report on the effectiveness of Internal Control over Financial Reporting (“ICFR”) of Kookmin Bank (the “Company”) as of December 31, 2025. The Company’s management is responsible for designing and operating ICFR and for its assessment of the effectiveness of ICFR. Our responsibility is to review the management’s report on the effectiveness of ICFR and issue a report based on our review. Management’s report on the effectiveness of ICFR of the Company states that “Based on the assessment results, Chief Executive Officer and ICFR Officer believe that the Company’s ICFR, as at December 31, 2025, is designed and operated effectively, in all material respects, in accordance with Conceptual Framework for Designing and Operating Internal Control over Financial Reporting.

Our review was conducted in accordance with ICFR review standards established by the Korean Institute of Certified Public Accountants. Those standards require that we plan and perform, in all material respects, the review of the management’s report on the effectiveness of ICFR to obtain a lower level of assurance than an audit. A review is to obtain an understanding of a company’s ICFR and consists principally of inquiries of management and, when deemed necessary, a limited inspection of underlying documents, which is substantially less in scope than an audit.

An entity’s ICFR is a process effected by those charged with governance, management, and other personnel, designed to provide reasonable assurance regarding the preparation of reliable financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS). An entity’s ICFR includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS), and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and directors of the entity; and (3) provide reasonable assurance regarding prevention, or timely detection and correction of unauthorized acquisition, use, or disposition of the entity’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, ICFR may not prevent, or detect and correct, misstatements. Also, projections of any assessment of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on our review, nothing has come to our attention that causes us to believe that management’s report on the effectiveness of ICFR, referred to above, is not presented fairly, in all material respects, in accordance with Standards for Evaluating and Reporting Internal Control over Financial Reporting.

Our review is based on the Company’s ICFR as of December 31, 2025, and we did not review management’s assessment of its ICFR subsequent to December 31, 2025. This report has been prepared pursuant to the Acts on External Audit for Stock Companies, etc. in Korea and may not be appropriate for other purposes or for other users.

Design and operation of ICFR is the responsibility of the Company’s management, including the Chief Executive Officer and the Internal Accounting Manager(collectively, “We”, “Our” or “Us”).

We used the ‘Conceptual Framework for Designing and Operating Internal Control over Financial Reporting’ established by the Operating Committee of Internal Control over Financial Reporting in Korea(the “ICFR Committee”) as the criteria for design and operation of the Company’s ICFR. And we conducted an evaluation of ICFR based on the Appendix 6 ‘Standards for Evaluating and Reporting on Internal Control over Financial Reporting’ for the Detailed Enforcement Rule of the Regulation on External Audit and Accounting.

Based on our assessment, we concluded that the Company’s ICFR is designed and operated effectively as of December 31, 2025, in all material respects, in accordance with the ‘Conceptual Framework for Designing and Operating Internal Control over Financial Reporting’.

We certify that this report does not contain any untrue statement of a fact, or omit to state a fact necessary to be presented herein.
