(English Translation of a Report Originally Issued in Korean)

To the Shareholders and the Board of Directors of

KB Financial Group Inc.

Opinion

We have audited the accompanying consolidated financial statements of KB Financial Group Co., Ltd. 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).

We also have audited, in accordance with Korean Standards on Auditing, the Company’s Internal Control over Financial Reporting for consolidation purposes as of December 31, 2025, based on Conceptual Framework for Designing and Operating Internal Control over Financial Reporting, and our report dated March 6, 2026 expressed an unqualified opinion.

Basis for Opinion

We conducted our audits in accordance with Korean Standards on Auditing. Our responsibilities under those standards are further described in theAuditor’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.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Allowance for expected credit losses on loans measured at amortized cost

As described in Note 10 to the consolidated financial statements, loans measured at amortized cost amount to ~~W~~497,384,240 million, with allowances for credit losses of ~~W~~5,406,196 million as of December 31, 2025. The Group measures expected credit losses on loans measured at amortized cost based on both individual and collective assessments. Individual assessment of expected credit losses is performed based on estimates of future forecast cash flow, and collective assessment of expected credit losses is involved with a variety and complex variable inputs and assumptions that require management’s estimates and judgments.

The principal considerations for our determination that performing procedures relating to the allowance for credit losses of loans measured at amortized cost is a key audit matter are: (i) there was significant judgement by management in determining the allowance, which in turn led to a high degree of auditor subjectivity in performing procedures related to the impairment models, key assumptions, such as probability of default, loss given default, credit risk ratings and determination of the forward-looking information and the expected future cash flows related to individual exposures; (ii) there was significant judgement and effort in evaluating audit evidence related to these models, judgments and assumptions used to determine the allowance; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Our audit procedures to address the Key Audit Matter included the following:

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the estimation process, which included controls over the data, models and assumptions used in determining the allowance for credit losses. These procedures also included, among others, the involvement of professionals with specialized skill and knowledge to assist in testing management’s process to estimate the allowance for credit losses including evaluating the appropriateness of methodology and models, and evaluating the reasonableness of key assumptions and the accuracy of the inputs used in the impairment models, such as probability of default, loss given default and credit risk ratings and determination of the forward-looking information. When evaluating the impairment models using probability of default and loss given default and the forward-looking information, we assessed their reasonableness and accuracy against external data and economic events that have occurred. We also assessed the reasonableness and the accuracy of borrower credit risk ratings and expected future cash flows related to individually assessed exposures.

Loss ratio assumptions used to estimate fulfilment cash flows of insurance contracts

As described in Note 38 to the consolidated financial statements, the net book value of the liability for remaining coverage was ~~W~~50,330,602 million, which is presented as insurance contract liabilities, reinsurance contract liabilities, insurance contract assets, and reinsurance contract assets in the consolidated statement of financial position as of December 31, 2025. As described in Notes 2 and 3, the Group estimates future cash flows using various actuarial assumptions as inputs. Among the actuarial assumptions, the calculation of loss ratio assumptions includes various and complex inputs, including historical data, and management’s estimates and judgement.

The principal considerations for our determination that performing procedures relating to the loss ratio assumptions used to estimate fulfilment cash flows of the insurance contracts is a key audit matter are: (i) there was significant judgement by management in determining the loss ratio, which in turn led to a high degree of auditor subjectivity in performing procedures related to the estimation fulfilment cash flows of the insurance contracts; (ii) there was significant judgement and effort in evaluating audit evidence related to these models, judgments and assumptions used to determine the loss ratio; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Our audit procedures to address the Key Audit Matter included the following:

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 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 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.
•	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.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partner on the audit resulting in this independent auditor’s report is Hee-Won Seo, Certified Public Accountant.

2. Basis of Preparation

2.1 Application of Korean IFRS

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.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

2.1.1 The Group has applied the following new and amended standards for the first time for its annual reporting period commencing January 1, 2025.

- Amendment of Korean IFRS 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 Group 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 Group is exposed. These amendments do not have a material impact on the financial statements.

- Amendments to Korean IFRS No.1117 “Insurance Contract” – Disclosures relating to lapse rates for insurance contracts with no or lowsurrender values

The amendments add a disclosure requirement to disclose, where the estimation techniques used for the inputs in measuring insurance contracts differ from the estimation techniques principally required under insurance-related laws or regulations and such differences are considered relevant and material to users of the financial statements, the nature of those differences and their effects on the financial statements. The amendments are effective from December 31, 2025 and are applied to the first annual reporting period ending on or after the effective date. The amendments remain effective through the annual reporting period ending on December 31, 2029. The amendments do not have a material 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 Group.

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

Korean IFRS No.1109 Financial Instruments and Korean IFRS No.1107 Financial Instruments: Disclosures have been amended to respond to recent questions arising in practice, and to include new requirements. The amendments should be applied for annual periods beginning on or after January 1, 2026, and earlier application is permitted. The amendments do not have a significant impact on the financial statements.

These amendments:

•	clarify the date of recognition and derecognition of some financial assets and liabilities, with a new exception<br>for some financial liabilities settled through an electronic cash transfer system;
•	clarify and add further guidance for assessing whether a financial asset meets the solely payments of principal<br>and interest (SPPI) criterion;

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

Korean IFRS No.1118 “Presentation and Disclosure in Financial Statements” replaces Korean IFRS No.1001 “Presentation of Financial Statements.” Korean IFRS No.1118 introduces new presentation requirements, particularly with respect to the definition of operating profit or loss, which are expected to enhance comparability of financial performance among similar entities. In addition, the disclosure requirements for management-defined performance measures are intended to improve transparency. The Standard is effective for annual reporting periods beginning on or after January 1, 2027, with early adoption permitted. In accordance with the retrospective application requirements of the Standard, the Group will restate the comparative information for the year ending December 31, 2026 in accordance with Korean IFRS No.1118.

The Group has not yet adopted Korean IFRS No.1118 and is currently assessing the impact that the application of the Standard will have on its financial statements. The Group has prepared a transition plan and is on track to report their first Korean IFRS No.1118-compliant interim financial statements for the period ending March 31, 2027 and annual financial statements for the period ending December 31, 2027.

2.2 Measurement Basis

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

2.3 Functional andPresentation 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 Parent Company’s functional and presentation currency.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

2.4 Critical Accounting Estimates

The Group applies accounting policies and uses judgements, 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.

If a certain portion of the taxable income is not used for investments, wages, etc. in accordance with the Korean regulation called ‘Special Taxation for Facilitation of Investment and Mutually-beneficial Cooperation’, the Group is liable to pay additional income tax calculated based on the tax laws. Therefore, the effect of recirculation of corporate income should be reflected in current and deferred income tax. As the Group’s income tax is dependent on the actual investments, wages, etc. per each year, there are uncertainties in measuring the final tax effects during the period when the tax law is applied.

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 material 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, debt instruments measured at fair value through other comprehensive income, and lease receivables. 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.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

2.4.4 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.

2.4.5 The judgment and estimation uncertainty in measurement of insurance contracts

2.4.5.1 Methods used to measure the future cash flows and estimation process of input variable

The estimated future cash flows are measured as the probability-weighted average of all possible outcomes, utilizing all reasonable and relevant information available without excessive cost or effort. Market and non-market variables are considered in measuring the cash flows within the boundary of the insurance contract. While deterministic scenarios (representing a range of probabilities) are typically used for calculating the probability-weighted average, probabilistic scenarios are employed when cash flows are influenced by complex underlying factors and nonlinear responses to economic conditions. The cash flows within the boundary of an insurance contract portfolio include both directly attributable cash flows and cash flows allocated from a higher level than the insurance contract portfolio. These cash flows are systematically and reasonably allocated, ensuring consistent methods are applied for similar types of cash flows.

The key assumptions used in estimating the future cash flows of the Group are as follows:

Loss ratio: The loss ratio refers to the ratio of insurance claims paid to policyholders to the premiums received by the insurance company for providing risk coverage services to policyholders. The loss ratio, which is an estimation of future premiums and claims payable, is estimated based on objective and reliable data, using the best available methods to suit the intended application. Objective and reliable data refers to the most recent measured results made using the Group’s experience statistics, insurance industry statistics, or national statistics, and others. It also means the best method that reasonably distinguishes characteristics such as the policyholder’s gender, contract type, risk characteristics by distribution channel, and others.
Expense ratio: Expense ratio refers to the costs incurred by insurance companies for the sale and management of insurance contracts. Expense ratio is calculated primarily considering the ongoing costs incurred by the insurance company, taking into account the going concern, and includes the allocation of both fixed and variable indirect expenses directly related to insurance contracts. Expense ratio also considers costs such as contract acquisition expense (regardless of whether premiums are paid or not), contract maintenance expense, and claims expense, distributed in order to manage cost by product and distribution channel.
Lapse ratio: The lapse ratio is an estimate of future cancellations or lapses of insurance contracts among current customers of the insurance company. It is calculated for the purpose of predicting the level of future current premium payments and cancellation refunds. The statistics used for estimation primarily rely on experience statistics of the Group, and lapse ratio is calculated based on characteristics such as product type, distribution channel, payment method, and others, which can significantly affect lapse ratio.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

2.4.5.2 Estimation of Discretionary Cash Flows

Some contracts issued by the Group grant discretion to the Group regarding cash flows to be paid to policyholders. Changes in discretionary cash flows are considered related to future services, and adjust the contractual service margin. The Group identifies changes in discretionary cash flow by identifying assured cash flows at the initial recognition date of the contract. However, if it is not possible to distinguish between the portion considered assured and the portion considered discretionary, the profit within the estimated fulfillment cash flows is considered assured, and is updated to reflect current assumptions related to financial risk.

2.4.5.3 Estimation of Risk Adjustment for Non-Financial Risk

Risk adjustment for non-financial risk is to adjust the present value estimates of future cash flows to reflect the compensation required by the Group for bearing the uncertainty about the amount and timing of cash flows arising from non-financial risk. This adjustment reflects the uncertainty of cash flows arising from all non-financial risks related to the insurance contracts and is estimated separately from all of the other estimates. The Group uses the confidence lever technique and the cost of capital methods for determining the risk adjustment for non-financial risk. Changes in risk adjustment for non-financial risk are disclosed separately for insurance service results and insurance finance income. The Group calculates this adjustment considering the diversification effect at the consolidated level and then allocated to individual contract units.

2.4.5.4 Estimation of Discount Rate

The discount rate should only include relevant factors such as the time value of money, characteristics of cash flows from insurance contracts, and liquidity characteristics, and should be calculated using observable input variables to the maximum extent possible. The discount rate should also reflect all reasonable and supportable information on internal and external non-market variables available without undue cost or effort. The Group estimates the discount rate using a bottom-up approach.

In the bottom-up approach, the discount rate is calculated using an unleveraged yield curve adjusted to reflect the characteristics of cash flows and liquidity of insurance contracts. To reflect the liquidity characteristics of insurance contracts, the risk-free yield curve is adjusted for illiquidity premium.

2.4.5.5 Estimation of Investment Component

The investment component is the amount that the Group must repay to policyholders under insurance contracts in all circumstances, regardless of the occurrence of insurance events. The Group classifies cash outflows such as maturity refunds, cancellation refunds, annuity payments, and cash flows related to insurance policy loans as investment components.

2.4.5.6 Estimation of Coverage Units

The quantity of insurance contract services provided is calculated based on the expected coverage period and maximum coverage amount (insurance amount), and for investment (related) services it is calculated based on the premium reserve (net of insurance policy loans). If insurance contracts within the group provide multiple services, weights are applied based on the total premium of each service. The quantity of services for each period and expected coverage period are calculated based on the expected persistency ratio applied in estimating the fulfillment cash flows, applied the present value effect.

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.

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.1.1 Subsidiaries (cont’d)

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.

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 and joint ventures

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.

Joint ventures are investments in which the Group has joint control over economic activities pursuant to contractual arrangement. Decisions about strategic financial and operating policies require unanimous consent of the parties sharing control.

Investments in associates and joint ventures 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 or joint ventures 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 or joint ventures’ accounting policies conform to those of the Group when the associates or joint ventures’ financial statements are used by the Group in applying the equity method.

If the Group’s share of losses of associates and joint ventures 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 investee.

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.

December 31, 2025 and 2024

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.

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.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.2.2 Foreign operations (cont’d)

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.

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, then foreign currency difference arising from that monetary item is recognized in the 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.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

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.

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<br>the measurement date
Level 2 :	Inputs other than quoted prices included within Level 1 that are observable for the asset or liability,<br>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.

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, bid-ask spread, liquidity risk, and others.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.3.2.2 Fair value (cont’d)

The Group uses 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.

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 regulations. 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 set off 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.

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:

•	Debt instruments that are held within a business model whose objective is achieved by both collecting contractual<br>cash flows and selling financial assets, and where the assets’ cash flows represent solely 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<br>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.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

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 2 approaches<br>
•	Simplified approach: for trade receivables, contract assets, and lease receivables
---	---
•	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) and
---	---
•	Credit delinquency information of Korea Credit Information Services, etc.
---	---

December 31, 2025 and 2024

3.6 Expected Credit Losses of Financial Assets (Debt Instruments) (cont’d)

Under simplified approach, the Group always measures loss allowances at an amount equal to lifetime expected credit losses. Under credit-impaired approach, the Group only recognizes the cumulative changes in lifetime expected credit losses since initial recognition as loss allowances at the end of the reporting period. In assessing credit impairment, the Group uses definition of default as in the new Basel Accord which rules calculation of Capital Adequacy Ratio.

The Group generally considers the loan to be credit-impaired if one or more of the following criteria are met:

•	90 days or more past due
•	Legal proceedings related to collection
---	---
•	A borrower registered on the credit management list of Korea Federation of Banks
---	---
•	A corporate borrower with the credit rating C and D
---	---
•	Refinancing and
---	---
•	Debt restructuring, 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 relevant risk components are correlated with the economic cycle and uses statistical methodologies to estimate the relationships between key macroeconomic variables and risk components used in the measurement of expected credit losses. The Group utilizes more than 15 years of historical time-series data to derive such correlations and incorporates the results into the risk components used in calculating expected credit losses.

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

Key macroeconomic variables
Benchmark interest rate	(+	)
AA- rated corporate bond<br>(3-year)	(+	)
BBB- rated corporate bond<br>(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	(+	)
Growth rate of private consumption	(-	)
Rate of increase or decrease in facilities investments	(-	)
Rate of increase or decrease in construction investments	(-	)
Unemployment rate	(+	)
Household loan growth rate	(-	)
CD distribution yield	(+	)

December 31, 2025 and 2024

3.6.1 Forward-looking information (cont’d)

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 a probability-weighted approach incorporating multiple macroeconomic scenarios, including optimistic, baseline, adverse, and crisis scenarios, taking into account potential credit risks arising from the uncertain domestic and global financial environment and the sharp economic downturn.

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.) among financial assets with the credit risk has increased significantly or 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 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.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.7.2 Derivative financial instruments for fair value hedges (cont’d)

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.

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 hedging instrument expires or 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 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.

3.7.6 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 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.

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	Declining-balance/ Straight-line	4~15 years
Equipment and vehicles	Declining-balance/ Straight-line	3~15 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		20~40 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	3 ~ 19 years
Software	Straight-line	3 ~ 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.

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. However, 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.

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

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.

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.

In addition, the change in fair value of the financial liability designated at fair value through profit or loss that is attributable to change in the credit risk of that liability, the Group presents this change in other comprehensive income, and does not recycle this to profit or loss in accordance with Korean IFRS No.1109. However, if this treatment creates or enlarges an accounting mismatch, the Group recognizes this change 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 Insurance Contracts

KB Insurance Co., Ltd. and KB Life Insurance Co., Ltd., the subsidiaries of the Group, issue insurance contracts. The Group accounts for these contracts by applying Korean IFRS No.1117.

3.14.1 Definition and classification of insurance contracts

Insurance contract is defined as a contract under which one party (the issuer) accepts significant insurance risk from another party (the policyholder) by agreeing to compensate the policyholder if a specified uncertain future event (the insured event) adversely affects the policyholder. This assessment is carried out for each contract individually at the date of inception. The Group determined that the insurance risk related to the contract is significant if the issuer has to pay a significant additional benefits in any scenario that has commercial substance, even if the insured event is extremely unlikely, or even if the expected present value of the contingent cash flows is a small proportion of the expected present value of the remaining cash flows from the insurance contract.

The Group issues insurance contracts that contain participation features, allowing policyholders to participate in the investment returns of the Group, in addition to being compensated for insurance risks. Contracts with participation features are classified as insurance contracts with direct participation features if they meet the following criteria. At the beginning of an insurance contract, the Group evaluates whether the contract meets the following criteria.

•	The contractual terms specify that the policyholder participates in a share of a clearly identified pool of<br>underlying items
•	The Group expects to pay to the policyholder an amount equal to a substantial share of the fair value returns on<br>the underlying items
---	---
•	the Group expects a substantial proportion of any change in the amounts to be paid to the policyholder to vary<br>with the change in fair value of the underlying items
---	---

Furthermore, the Group issues investment contracts with discretionary participation features, which are associated with groups of assets identical to those of insurance contracts and share similar economic characteristics with insurance contracts.

Notes to the Consolidated Financial Statements

3.14.2 Level of aggregation

The Group identifies portfolios by aggregating insurance contracts subject to similar risks and managed together. Each portfolio is segmented into groups of insurance contracts applying the recognition and measurement requirements of IFRS 17. The Group distinguishes insurance contracts based on their issuance date at initial recognition. A cohort consists of contracts issued within a 12-month period, and is further segmented into three groups based on the possibility of becoming onerous.

•	a group of contracts that are onerous at initial recognition
•	a group of contracts that at initial recognition have no significant possibility of becoming onerous subsequently<br>
---	---
•	a group of the remaining contracts in the portfolio
---	---

The possibility of insurance contracts, at the lowest level of group of contracts, becoming onerous is determined based on the expected cash flows (fulfillment cash flow decided based on probability weighting) at initial recognition. The Group does not reassess the composition of the groups decided at the initial recognition date subsequently.

3.14.3 Recognition

The group recognizes a group of insurance contracts it issues from the earliest of the following:

•	the beginning of the coverage period of the group of contracts
•	the date when the first payment from a policyholder in the group becomes due
---	---
•	for a group of onerous contracts, when the group becomes onerous.
---	---

The group delays the recognition of a group of reinsurance contracts held that provide proportionate coverage until the date that any underlying insurance contract is initially recognized, if that date is later than the beginning of the coverage period of the group of reinsurance contracts held.

The group recognizes investment contracts with discretionary participation features at the date the Group becomes a party to the contract.

3.14.4 Contract boundary

Measurement of group of contracts includes all future cash flows within the contract boundaries. The Group decides that cash flows are within the boundary of an insurance contract if they arise from substantive rights and obligations that exist during the reporting period in which the entity can compel the policyholder to pay the premiums or in which the entity has a substantive obligation to provide the policyholder with insurance contract services.

A substantive obligation to provide insurance contract services ends when:

•	The Group has the practical ability to reassess the risks of the particular policyholder and, as a result, can<br>set a price or level of benefits that fully reflects those risks
•	The Group has the practical ability to reassess the risks of the portfolio of insurance contracts that contains<br>the contract and, as a result, can set a price or level of benefits that fully reflects the risk of that portfolio; and the pricing of the premiums up to the date when the risks are reassessed does not take into account the risks that relate to<br>periods after the reassessment date.
---	---

The Group evaluates contract boundaries at initial recognition and each subsequent reporting date to reflect changes in circumstances affecting substantive rights and obligations.

3.14.5 Measurement: Insurance contracts not applying the premium allocation approach

3.14.5.1 Measurement on initial recognition

The group measures group of contracts as the sum of the fulfillment cash flows and the contractual service margin at the initial measurement. Fulfillment cash flows comprise estimates of future cash flows, an adjustment to reflect the time value of money and the financial risks related to the future cash flows, and a risk adjustment for non-financial risk.

Estimates of future cash flows is calculated by the probability-weighted average of all possible outcomes using all reasonable and supportable information available without undue cost or effort, considering both market and non-market variables, for cash flows within the contract boundary. The Group updates the estimates using all new information available, including information about past trends and evidence.

The risk adjustment for non-financial risk represents a liability that reflects the compensation that the insurer requires for bearing the uncertainty about the amounts and timing of cash flows arising from non-financial risk. Non-financial risks that are the subject of risk adjustment include insurance risk and other non-financial risks (such as lapse risk and expense risk). The Group calculates the risk adjustment for non-financial risk using techniques such as the confidence level method and the cost of capital method. The Group calculates the risk adjustment for non-financial risk at the level of the company, and after considering diversification effects, allocates it to individual groups of insurance contracts.

Contractual service margin represents the unearned profit the entity will recognize as it provides insurance contract services in the future. The group measures the contractual service margin on initial recognition of a group of insurance contracts at an amount that results in no income or expenses if the fulfillment cash flows at the initial recognition are net inflows. On the other hand, if the fulfillment cash flows are net outflow at the initial recognition, the Group classifies the group of contracts as an onerous group, recognizes the expected net outflow as an expense and manages loss component for subsequent measurement.

3.14.5.2 Subsequent measurement of the general measurement model

At the end of each reporting period, the carrying amount of group of contracts is the sum of estimated liability for incurred claims and liability for remaining coverage. Liability for remaining coverage comprises contractual service margin and expected fulfillment cash flows related to future services allocated to the group of contracts at the end of the reporting period. Liability for incurred claims comprises unpaid claims and insurance expenses, including reported but not yet paid claims, incurred but not reported claims, and dividends payable according to supervisory regulations.

The Group updates the fulfillment cash flows of both liability for incurred claims and liability for remaining coverage at each reporting date to reflect current estimates of the amounts, timing, and uncertainty of future cash flows, considering not only discount rates and other financial variables but also non-financial risk.

Experience adjustments is the differences between the following:

•	The estimated expected cash flows at the beginning of reporting period and the actual cash flows received during<br>the reporting period (including premiums received, cash flows related to insurance acquisition, and premium taxes paid)

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.14.5.2 Subsequent measurement of the general measurement model (cont’d)

•	The estimated expected cash flows at the beginning of reporting period and the actual insurance service expenses<br>incurred during the reporting period (excluding insurance acquisition costs)

Experience adjustments related to current or past services are recognized in profit or loss. For incurred claims (including those that have been incurred but not reported) and other incurred insurance service expenses, experience adjustments are always related to current or past services and are included as part of insurance service expenses in profit or loss. Changes in fulfillment cash flows related to future services are included in liability for remaining coverage by adjusting contractual service margin.

For insurance contracts without direct participation features, the carrying amount of the contractual service margin of a group of contracts at the end of the reporting period equals the carrying amount at the start of the reporting period adjusted for:

•	the effect of any new contracts added to the group
•	interest accreted on the carrying amount of the contractual service margin during the reporting period, measured<br>at the discount rates determined at initial recognition
---	---
•	the changes in fulfilment cash flows relating to future service, except to the extent that:<br>
---	---
(i)	such increases in the fulfilment cash flows exceed the carrying amount of the contractual service margin,<br>giving rise to a loss
---	---
(ii)	such decreases in the fulfilment cash flows are allocated to the loss component of the liability for remaining<br>coverage
---	---
•	the effect of any currency exchange differences on the contractual service margin
---	---
•	the amount recognized as insurance revenue because of the transfer of insurance contract services in the period,<br>determined by the allocation of the contractual service margin remaining at the end of the reporting period.
---	---

When fulfillment cash flows related to future services increase additionally, the cash flows result in an increase in the loss component of the group of contracts, and the increased loss component is recognized in profit or loss when the cash flows occur. Subsequently, decreases in fulfillment cash flows related to future services do not adjust contractual service margin until the loss component is fully recovered through profit or loss.

3.14.5.3 Subsequent Measurement of the Variable Fee Approach

The Group issues insurance contracts with direct participation features that provide significant investment-related services. Except for the following, the Group applies the same accounting policy for measuring insurance contracts under the variable fee approach as for measuring insurance contracts under the general measurement model.

For insurance contracts with direct participation features, the carrying amount of the contractual service margin of a group of contracts at the end of the reporting period equals the carrying amount at the start of the reporting period adjusted for the amounts specified below:

•	the effect of any new contracts added to the group
•	the change in the amount of the Group’s share of the fair value of the underlying items except to the<br>extent that
---	---
(i)	The amount of contractual service margin recognized in profit or loss due to the offsetting effect of risk<br>mitigation instruments
---	---
(ii)	the decrease in the amount of the Group’s share of the fair value of the underlying items exceeding the<br>carrying amount of the contractual service margin, giving rise to a loss
---	---
(iii)	the increase in the amount of the Group’s share of the fair value of the underlying items that causes<br>reversal of loss component of an onerous group
---	---

3.14.5.3 Subsequent Measurement of the Variable Fee Approach (cont’d)

•	the changes in fulfilment cash flows relating to future service, except to the extent that:<br>
(i)	The amount of contractual service margin recognized in profit or loss due to the offsetting effect of risk<br>mitigation instruments
---	---
(ii)	The increases in the fulfilment cash flows that exceeds the carrying amount of the contractual service margin,<br>giving rise to a loss
---	---
(iii)	The decreases in the fulfilment cash flows that causes reversal of loss component of an onerous group<br>
---	---
•	the effect of any currency exchange differences arising on the contractual service margin
---	---
•	the amount recognized as insurance revenue because of the transfer of insurance contract services in the period,<br>determined by the allocation of the contractual service margin remaining at the end of the reporting period (before any allocation) over the current and remaining coverage period
---	---

All adjustments to contractual service margins are measured, considering the present value of currency, which is currently measured, taking into account all financial variables that affect the fair value gains arising from the underlying items. When applying the variable fee approach, the changes in the fulfillment cash flows adjusting the contractual service margin is composed of changes in the Group’s share of the fair value of the underlying items and the changes in the fulfillment cash flows that do not vary based on returns on the underlying items. the changes in the fulfillment cash flows that do not vary based on returns on the underlying items are as follows:

•	changes in the effect of currency risk and the effect of financial risk not arising from underlying items, such<br>as the impact of financial guarantees
•	experience adjustments arising from premiums received during the period related to future services<br>
---	---
•	changes in estimated future cash flows of liability for remaining coverage
---	---
•	differences in the payment timing of investment components
---	---
•	changes in risk adjustment for non-financial risk related to future<br>services
---	---

3.14.5.4 Reinsurance contract

The Group applies the same accounting policy for measuring reinsurance contracts as for measuring insurance contracts, except for the following.

The Group includes all effects of risks related to the reinsurer’s default (including effects from security and losses due to disputes) when measuring the reinsurance contract group. The Group remeasures the effects of the reinsurer’s default risk at the end of each reporting period and recognizes the changes in the effects of default risk in profit or loss. The Group calculates the risk adjustment for non-financial risks to reflect the risks transferred to the reinsurer. Reinsurance contracts are not classified as onerous groups and do not recognize in profit or loss the expected outflows at the initial recognition, even if the fulfillment cash flows at initial recognition are outflows, considering the nature of reinsurance. However, if the net cost of purchasing reinsurance coverage is related to events that have occurred before the reinsurance contract is purchased, such costs are recognized as expenses immediately.

3.14.5.5 Insurance revenue

The Group recognizes insurance revenue as the amount the Group expects to be entitled in exchange for provision of services arising from group of insurance contracts. Total insurance revenue for group of contracts is the amount received in premiums for the contracts, adjusted for financial effects and excluding all investment elements.

The amount of contractual service margin recognized as insurance revenue during the reporting period is determined by allocating the unamortized contractual service margin at the end of the reporting period for each unit of coverage provided during the reporting period and expected to be provided in the future. The number of coverage units in a group of contracts is the quantity of insurance contract services provided from insurance contracts within the group, and is determined based on the number of benefits provided and the expected duration of coverage under each contract.

Insurance acquisition cash flows are systematically allocated over each reporting period, recognized in equal amounts of insurance revenue and insurance expenses.

Loss component is allocated systematically, and the total amount allocated to the loss component becomes zero by the end of the coverage period of group of contracts. The portion of the allocated loss component for the reporting period is excluded from recognition in both insurance revenue and insurance expenses.

3.14.5.6 Insurance finance income or expenses

Insurance finance income consists of changes in the carrying amount of the groups of insurance contracts and reinsurance contracts arising from the effect of the time value of money and financial risk. The Group decides whether to disaggregate insurance finance income or expenses for the period between profit or loss and other comprehensive income for each portfolio. Systematic allocation involves allocating the expected total insurance finance income or expenses over the duration of the group of contracts, and recognizing the portion attributed to the reporting period in profit or loss and the remaining portion in other comprehensive income.

For insurance contracts where changes in financial risk related assumptions significantly impact the amounts paid to policyholders, the Group uses a single discount rate to allocate the modified expected insurance finance income or expenses for the remaining coverage period of the group of contracts. Otherwise, the Group calculates insurance finance income or expenses using the discount rate determined at the date of initial recognition.

Insurance finance income or expenses arising from contractual service margin is systematically allocated using the discount rate determined at the date of initial recognition.

When the Group transfers insurance contracts to a third party or derecognize them due to changes in insurance contract terms, the accumulated other comprehensive income related to those insurance contracts is reclassified to profit or loss.

3.14.5.7 Reinsurance revenue and expenses

The Group recognizes separately the amounts recovered from reinsurers and the allocation of reinsurance premiums paid in reinsurance contracts. Changes in the carrying amount of reinsurance assets for remaining coverage resulting from the reinsurance services received are recognized as reinsurance expenses, while amounts recovered from reinsurers are recognized as reinsurance income.

3.14.6 Premium allocation approach

3.14.6.1 Underlying insurance

For general insurance and automobile insurance, if the coverage period of each contract within the group of contracts (including insurance contract services within the contract boundary) is less than one year or if the premium allocation approach is reasonably expected to measure the liability for remaining coverage for the group without significant differences from the application of the general model requirements, the premium allocation approach is applied to simplify the measurement of the group of insurance contracts.

The carrying amount of the liability for remaining coverage at the time of initial recognition of each group of contract is calculated by deducting the insurance acquisition cash flows allocated to the group of insurance at the acquisition date from the premium receipts at the time of initial recognition, and adding or subtracting the amount resulting from removing previously recognized assets or liabilities for cash flows related to the group of contract at the time of initial recognition.

Subsequently, the carrying amount of the liability for remaining coverage is calculated by adding the received premiums and the amortization of the insurance acquisition cash flows, and deducting the insurance acquisition cash flows and the amount recognized as insurance revenue for services provided. However, if the insurance acquisition cash flows recognized as expenses when it incurs those costs because the coverage period of each contract in the group at initial recognition is no more than one year, the insurance acquisition cash flow is not considered for calculating the liability for remaining coverage.

If at any time during the coverage period, facts and circumstances indicate that a group of insurance contracts is onerous, the difference between the carrying amount of the liability for remaining coverage and the current estimate of the fulfilment cash flows related is calculated, added to the the liability for remaining coverage, and recognized as a loss in profit or loss.

The Group determines that the liability for remaining coverage subject to the insurance premium allocation approach do not have significant financial elements, and therefore does not adjust the carrying amount of the liability for remaining coverage for reflecting the effect of the time value of money and financial risk.

3.14.6.2 Reinsurance

The Group applies the same accounting policy for measuring reinsurance contracts applying the premium allocation approach (general reinsurance, automobile reinsurance, and long-term non-proportional reinsurance) as for measuring insurance contracts with the exception of the following: The Group includes all effects of risks related to the reinsurer’s default (including effects from security and losses due to disputes) when measuring the reinsurance contract group. The Group remeasures the effects of the reinsurer’s default risk at the end of each reporting period and recognizes the changes in the effects of default risk in profit or loss. Reinsurance contracts are not classified as onerous groups and do not recognize in profit or loss the expected outflows at the initial recognition, even if the fulfillment cash flows at initial recognition are outflows, considering the nature of reinsurance. However, if the net cost of purchasing reinsurance coverage is related to events that have occurred before the reinsurance contract is purchased, such costs are recognized as expenses immediately.

3.14.7 Modification and derecognition

The Group derecognizes an insurance contract when the insurance contract is extinguished because of reasons such as obligation specified in the insurance contract having been expired, discharged or cancelled. Additionally, if the conditions of the contract have changed to such an extent that the accounting treatment of the contract would have been significantly different had the new conditions existed from the beginning, the Group derecognizes the existing contract and recognizes it as a new contract. If the change in contract conditions is not significant, the Group accounts for it as a change in the estimate of fulfillment cash flows.

3.15 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.

3.16 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.

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.

3.17 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.

3.17.1 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.

3.17.2 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.

3.17.3 Treasury shares

If the Group acquires its own equity instruments, these are accounted for as treasury shares and are deducted directly from equity. No gains or losses are recognized in profit or loss on the purchase, sale, issue or retirement of own equity instruments. If an entity within the Group acquires and retains treasury shares, the consideration paid or received is directly recognized in equity.

3.17.4 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. 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.

3.18 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.
---	---

3.18.1 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.

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.

3.18.2 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.

3.18.2.1 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.

3.18.2.2 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.

3.18.2.3 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 controls 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.

3.18.3 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)
---	---

3.18.4 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.

3.19 Employee Compensation and Benefits

3.19.1 Post-employment benefits

3.19.1.1 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.

3.19.1.2 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 independent actuaries 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 resulted 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.

3.19.2 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.

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.

3.19.3 Share-based payment

The Group provides its executives and employees with stock grants, mileage stock, and long-term share-based payments programs. When stock grants are exercised, the Group can either select to distribute newly issued shares or treasury shares or compensate in cash based on the share price. When mileage stock and long-term share-based payments are exercised, the Group pays the amount equivalent to share price of KB Financial Group Inc. in cash.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.19.3 Share-based payment (cont’d)

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 and long-term share-based payments program, the Group accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions, which are recognized as expense 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.

3.19.4 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.

3.20 Income Tax Expense

Income tax expense comprises current tax expense and deferred income tax expense. Current and deferred income tax 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.

3.20.1 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.

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 set off the recognized amounts and (b) intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

KB Financial Group Inc. and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2025 and 2024

3.20.2 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, associates, and joint ventures, 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 set off 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.

3.20.3 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.

3.20.4 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.

3.21 Earnings per Share

The Group calculates basic earnings per share amounts and diluted earnings per share amounts for profit or loss attributable to ordinary equity holders of the Parent Company and presents them in the consolidated statement of comprehensive income. Basic earnings per share is calculated by dividing profit or loss attributable to ordinary equity holders of the Parent Company by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per share is calculated by adjusting the profit or loss attributable to ordinary equity holders of the Parent Company and weighted average number of shares outstanding, taking into account all potential dilution effects, such as exchangeable bonds and share-based payments given to employees.

3.22 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
•	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).

3.22 Leases (cont’d)

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.

3.23 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.

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 in an integrated way.

4.2.2 Credit risk management

The Group measures the expected loss and economic capital for the assets subject to credit risk management, including on-balance and off-balance assets, and uses them as management indicators. The Group allocates and manages credit risk economic 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 Kookmin Bank’s loan customers (individuals and corporates) are assigned a credit rating and managed by a comprehensive internal 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 Kookmin 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, Kookmin 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.

KB Kookmin Card Co., Ltd.’s credit scoring system is divided into Application Scoring System (“ASS”) and Behavior Scoring System (“BSS”). For applications that meet the eligibility criteria for card issuance, the card will be issued only if the ASS credit rating is above the standard. KB Kookmin Card Co., Ltd.’s internal information, external information from the credit bureau company and others, and personal information on the application are used to calculate the ASS credit rating. The BSS, which is recalculated on a weekly basis, predicts the delinquency probability of cardholders, and utilizes it to monitor cardholders and portfolio risk.

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 of Kookmin Bank, a subsidiary, is in charge of loan policy, loan system, credit rating, credit analysis, follow-up management, and corporate restructuring. The Risk Management Group of Kookmin Bank 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. 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 Group measures the expected credit losses of loans classified as financial assets at amortized cost, by deducting allowances for credit losses. 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 financial statements.

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 risk management policies and liquidity 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 calculates and manages cumulative liquidity gap, liquidity ratio and others for all transactions and off-balance transactions related to liquidity, 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 consolidated statements of financial position which are based on discounted cash flows. The future interest payments for 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 include 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 interest rate risk management guidelines for non-trading positions. The entire process is carried out through consultation with the Risk Management Council and approval by the Risk Management Committee of the Group. However, insurance companies that are engaged in the insurance business are not subject to these guidelines and are monitored by setting internal capital limits for market risk and interest rate risk based on K-ICS.

In the case of Kookmin Bank, a major subsidiary, the 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.

Kookmin Bank’s Asset-Liability Management Committee (“ALCO”) determines interest rate and commission operating standards and Asset Liability Management (“ALM”) operation policies and enacts and revises relevant guidelines. The Risk Management Committee and the Risk Management Council monitor the establishment and enforcement of ALM risk management policies and enact and revise 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 ALM department, and reports related matters to the management independently.

Kookmin Bank is closely monitoring the outputs of various industry groups and markets that manage the transition to the new interest rate benchmark, including announcements by LIBOR regulation authority and various consultative bodies related to the transition to alternative interest rate. In response to these announcements, Kookmin Bank has completed most of the transition and replacement plans according to LIBOR transition programs and plans consisting of major business areas such as finance, accounting, tax, legal, IT, and risk. The program is under the control of the CFO and related matters are reported to the board of directors and consultative bodies with senior management as members. Kookmin Bank continues its efforts as a market participant to actively express opinions so that the index interest rate benchmark reform can be carried out in the direction of minimizing the financial and non-financial impacts and operational risks and minimizing confusion among stakeholders.

4.4.3 Trading position

4.4.3.1 Definition of a trading position

The target position should be made daily fair value assessment and should have no legal constrictions on sale and hedging.

•	The target position has no restrictions on the sale, and 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.
---	---

---	---

4.4.3.2 Observation method of market risk arising from trading positions

From January 2023, Subsidiaries of the Group use the Basel III standardized approach to measure market risk and manage it at the portfolio level(Prior to January 2023, Basel II standardized approach or Basel II internal models such as VaR). In addition, the Group controls and manages the risk of derivative financial instrument transactions in accordance with the Financial Supervisory Service regulations and enforcement rules.

4.4.3.3 Basel III standardized approach

Market risk regulatory capital is calculated as the sum of (a) sensitivities-based risk, (b) default risk, and (c) residual risk according to the Basel III standardized approach introduced in January 2023.

(a) Sensitivities-based risk, which is the basis of the Basel III standardized approach for market risk, calculates the expected loss for each risk factor by applying the risk weights and correlation parameter specified by the Basel Committee and summing them.

(b) Default risk is the risk from default of issuer of securities and derivatives and is calculated by applying risk weights based on the issuer’s credit rating.

(c) Residual risk is the risk imposed on atypical underlying instruments and is calculated by applying a certain percentage specified by the Basel Committee to the par value.

4.4.3.4 Details of risk factors

(a) Interest rate risk

Interest rate risk for trading positions usually arises from debt securities. The Group’s trading strategy is to gain short-term trading gains from interest rate fluctuations. The Group manages interest rate risk associated with trading portfolios using sensitivity analysis (Price Value of a Basis Point: PVBP).

(b) Stock price risk

Stock price risk usually arises from the portfolio of trading stocks. The portfolio of trading stocks consists of stocks listed on the exchange and derivatives linked to stocks, collective investment securities and others.

Currency risk arises from holding assets and liabilities which are denominated in foreign currency, and currency-related derivatives. Most of the net foreign currency exposures occur in the US dollars, the Chinese Yuan and the Indonesian Rupiah.

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

4.4.4.1 Qualitative disclosure

(a) Definition of interest rate risk for risk management and measurement purposes

Interest rate risk 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.

(b) Overall interest rate risk management and mitigation strategy

The interest rate risk management department establishes and sets interest rate risk management policies and limit once a year by a resolution of the Risk Management Council considering the mid to long-term management strategy and macroeconomic status. The interest rate risk management department analyzes interest rate risk crisis situations assuming abnormal interest rate fluctuations and reports the results to the Risk Management Council and observes changes in interest rate risk and compliance with risk limits to devise timely countermeasures and reports the management status regularly and frequently to the Risk Management Council. 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.

In order to measure the sensitivity of the economic value and earnings to changes in interest rates, the Group calculates monthly interest rate gap and duration gap for assets and liabilities.

(d) Interest rate shock and stress scenarios used to estimate changes in the economic value and in earnings

The Group calculates ΔEVE by applying following six interest rate shock and stress scenarios, and ΔNII by applying parallel shock up and parallel shock down scenarios.

•	Scenario 1: Parallel shock up
•	Scenario 2: Parallel shock down
---	---
•	Scenario 3: Steepener shock (short rates down and long rates up)
---	---
•	Scenario 4: Flattener shock (short rates up and long rates down)
---	---
•	Scenario 5: Short rates shock up
---	---
•	Scenario 6: Short rates shock down
---	---

(e) Key modeling assumptions used to measure interest rate risk for internal management purposes

The Group measures unfavorable changes in economic value resulting from changes in interest rates, following the interest rate risk calculation standards set by the Financial Supervisory Service.

(f) Interest rate risk hedging methodology and related accounting

Subsidiaries which are subject to interest rate risk measurement hedges interest rate risk through back-to-back interest rate swap transactions, which are the same as interest payment cash flows and officially document and manage the risk management strategy for hedge accounting, risk management objectives, hedging relationship, and assessment method for hedge effectiveness.

(g) Key modeling and parametric assumptions used in calculating ΔEVE and ΔNII

Subsidiaries which are subject to interest rate risk measurement calculate interest rate risk, including all cash flow of interest-sensitive assets and liabilities, and off-balance sheet items. The main assumptions of the IRRBB standard method for calculating ΔEVE, ΔNII are as follows:

(Classification of time buckets of cash flows (19 buckets in total))

4.5 Operational Risk

4.5.1 Concept

Operational risk of the Group refers to the risk of loss that may occur due to improper or incorrect internal procedures, personnel, systems or external events. Operational risk management plays a role in enhancing the stability and soundness of financial institutions by managing the appropriate level of capital and supplementing the internal control system.

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 Parent Company manages the Group’s overall operational risk, and each subsidiary establishes and implements operational risk management policies according to its own risk level and implements and operates related systems. The Group Risk Management Committee establishes and allocates risk capital of operational risk for each subsidiary, and subsidiaries manage operational risks at an appropriate level within the allocated risk capital.

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 9.0%, Tier 1 Capital ratio of 10.5%, and Total Capital ratio of 12.5%) as of December 31, 2025.

The Group’s capital is classified into three categories in accordance with the Detailed Regulations on Supervision of Financial Holding Companies 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 meets 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 Financial Holding Companies, and others.
---	---

The risk-weighted assets are the magnitude of the amount of risk inherent in the total asset held by the Group. The Group calculates risk-weighted assets by each risk (credit risk, market risk, and operational risk) based on the Detailed Regulations on Supervision of Financial Holding Companies and uses them to calculate capital adequacy ratio.

4.6 Capital Management (cont’d)

The Group evaluates and manages capital adequacy through separate internal policies. The evaluation of capital adequacy compares the size of available capital (the actual amount of available capital) 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.

Internal capital refers to the capital required to prevent the insolvency from future unexpected losses. The Group operates a system to measure, allocate, and manage internal capital to major subsidiaries by risk type.

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 same as 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 receivable<br>on demand. Fair value of general deposit is measured using Discounted Cash Flow (“DCF”) Model.
Securities		Fair value of securities and others that are traded in an active market is determined using the quoted prices. If there is no quoted price, fair value is determined using external professional valuation institutions. The<br>institutions use one or more valuation techniques that are deemed appropriate considering the characteristics of the financial instruments among DCF Model, Free Cash Flow to Equity Model, Comparable Company Analysis, Dividend Discount Model, Risk<br>Adjusted Discount Rate Method, and Net Asset Value Method.
Loans		Fair value of loans is determined using DCF Model discounting the expected cash flows, which are contractual cash flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Derivatives and financial instruments at fair value through profit or loss		Fair value of exchange traded derivatives is determined using quoted price 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 Finite Difference Method (“FDM”), Monte Carlo Simulation, Black-Scholes Model, Hull-white Model, Closed Form, and Tree Model or valuation<br>results from independent external professional valuation institutions.
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 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 DCF<br>Model.
Debentures		Fair value is determined using valuation results 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<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.
---	---

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.

6.2.3.2 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 (a) equity-related derivatives, currency-related derivatives, and interest rate related derivatives whose fair value changes are recognized in profit or loss, (b) financial liabilities designated at fair value through profit or loss, and (c) due from financial institutions, debt securities (including beneficiary certificates), equity securities, and loans 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:

^1^	For financial instruments at fair value through profit or loss, changes in fair value are calculated by<br>shifting principal unobservable input parameters such as discount rate, recovery rate, liquidation value, growth rate by ±1%p and volatility of underlying asset by ±1%p or ±10% and correlation coefficient by ±10%.<br>

^4^	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 rate of real estate price fluctuation by -1%p~1%p, and for beneficiary certificates whose underlying assets are<br>equity investments, changes in fair value are calculated by shifting principal unobservable input parameters such as liquidation value by -1%p~1%p and discount rate by -1%p~1%p. There is no significant correlation among major unobservable inputs.<br>

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)	2025			2024

6.4.3 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.

6.4.4 Securitization of Financial Assets

The structured entities subject to consolidation have issued asset-backed securities using the loans and other receivables held by the Group as securitized assets. As a result of these securitization transactions, the contractual cash flows of the securitized assets are transferred to the holders of the asset-backed securities. The Group, in relation to the transfer of financial assets for securitization, bears the contractual obligation to pay the cash flows to one or more recipients, such as repurchase agreements, for all transferred financial assets that exist but have not been derecognized as of the reporting date.

Details of carrying amounts of the underlying assets and the associated liabilities related to securitization transactions as of December 31, 2025 and 2024, are as follows:

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. Domestic exchange settlement debits and domestic exchange settlement credits are recognized in its net settlement balance in the consolidated statement of financial position because the Group has the legal right of offset and settles in net amount.

9. Derivative Financial Instruments and Hedge Accounting

The Group’s derivative operations focus on addressing the needs of the Group’s corporate clients to hedge their risk exposure and hedging the Group’s risk exposure that results from such client contracts. The Group also engages in derivative trading activities to hedge the interest rate risk and currency risk arising from the Group’s own assets and liabilities. In addition, the Group engages in proprietary trading of derivatives within the predetermined transaction limit.

The Group provides and trades a range of derivative financial instruments, including:

•	Interest rate swaps relating to interest rate risk in Korean won
•	Cross-currency swaps, forwards, and options relating to currency risk
---	---
•	Stock index options linked with the Korea Composite Stock Price Index (“KOSPI”)<br>
---	---

In particular, the Group applies fair value hedge accounting using interest rate swaps, currency forwards, and others to hedge the risk of changes in fair value due to the changes in interest rate and foreign exchange rate of structured debentures in Korean won, debentures in foreign currencies, structured deposits in foreign currencies, and others. The Group applies cash flow hedge accounting using interest rate swaps, currency swaps, and others to hedge the risk of changes in cash flows of floating rate debt securities in Korean won, borrowings in foreign currencies, group of loans measured at amortized cost, and others. In addition, the Group applies net investments in foreign operations hedge accounting by designating debentures in foreign currencies and cross currency forwards as hedging instruments to hedge the currency risk of net investments in foreign operations.

*	The recoverable amount exceeding carrying amount is the amount at the time of impairment testing.<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.

Cash-generating units to which goodwill has been allocated is 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 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. In relation to subsequent cash flows, it is assumed that cash flows will grow at a certain permanent growth rate. 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 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.

25. Net Defined Benefit Liabilities

25.1 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 recognized in the consolidated statement of financial position are calculated by the independent actuary in accordance with actuarial valuation method. The defined benefit obligation is calculated using the projected unit credit method. Assumptions based on market data and historical data such as discount rate, future salary increase rate, mortality, and consumer price index are used which are updated annually.

Actuarial assumptions may differ from actual results, due to changes in the market conditions, economic trends, and mortality trends which may affect net defined benefit liabilities and future payments. Actuarial gains and losses arising from changes in actuarial assumptions are recognized in the period incurred through other comprehensive income.

25.2 Changes in net defined benefit liabilities for the years ended December 31, 2025 and 2024, are as follows:

Salary increase rate (%)	0.00~7.00	0.00~7.00
Turnover rate (%)	0.00~47.65	0.00~38.60

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

25.8 Results of sensitivity analysis of significant actuarial assumptions as of December 31, 2024, are as follows:

	Changes inassumptions	Effect on defined benefit obligation
		Increase in<br>assumptions	Decrease in<br>assumptions
Discount rate	0.5%p	3.25% decrease	3.43% increase
Salary increase rate	0.5%p	3.43% increase	3.28% decrease
Turnover rate	0.5%p	0.19% decrease	0.19% 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.

Diluted earnings per share is calculated through increasing the weighted average number of ordinary shares outstanding by the weighted average number of additional ordinary shares that would have been outstanding assuming the conversion of all dilutive potential ordinary shares. The Group has dilutive potential ordinary shares such as stock grants and ordinary share exchange right of exchangeable bonds.

A calculation is done to determine the number of shares that could have been acquired at fair value (determined as the average market share price for the year) based on the monetary value of stock grants. The number of shares calculated above is compared with the number of shares that would have been issued assuming the settlement of stock grants.

Exchangeable bonds are included in potential ordinary shares from the exercisable date of the exchange right, and interest expense after tax for the period is added to profit for diluted earnings per share.

38.11 Risk Management of KB Insurance Co., Ltd.

38.11.1 Overview of insurance risk

Insurance risk is the risk that arises from a primary operation of insurance companies that is associated with underwriting of insurance contracts and payment of claims, which has the risk of greater loss incurring than anticipated by the Group. The Group manages insurance risk in different categories of long-term insurance, general insurance, and automobile insurance.

38.11.1.1 Key items of Long-term insurance

Mortality Risk		Risk of unexpected losses due to premature death compared to the insured’s expectations.
Longevity Risk		Risk of unexpected losses due to delayed death compared to the insured’s expectations.
Disability/Illness Risk		Risk of unexpected losses related to the insured’s disability and illness.
Long-term Property/Other Risks		Risk of unexpected losses related to property, expenses, indemnities, and other collateral in long-term insurance.
Termination Risk		Risk of losses due to unexpected exercise of legal rights or contractual options by policyholders.
Expense Risk		Risk of losses due to fluctuations in future costs and expenditure variations caused by inflation in relation to insurance contract costs.
Catastrophic Risk		Risk of extreme, exceptional losses (e.g., epidemics, major accidents) not considered in mortality risk, etc.

December 31, 2025 and 2024

38.11.1.2 Key items of general and automobile insurance

Price Risk		Risk of losses exceeding the expected mortality rate and expense ratio calculated when determining insurance premiums.
Reserve Risk		Risk of being unable to cover future insurance payments reserved for incurred but not reported insurance accidents.
Catastrophic Risk		Risk of losses due to extreme, exceptional risks not considered in insurance price risk and reserve risk.

38.11.2 Purposes, policies, and procedures to manage risk arising from insurance contracts

The risks associated with insurance contracts that the Group faces are insurance actuarial risk and underwriting risk. Each risk occurs due to insurance contract’s pricing and conditions of underwriting. In order to minimize the possibility of acquiring a bad contract, the Group has established and operated detailed underwriting guidelines and underwriting procedures by insurance type that specify detailed underwriting conditions according to the type of risk covered through pre-analysis of insured property. In addition, the Group is making efforts to reduce insurance actuarial risk by follow-up measures such as adjustments of premium rate, changes of sales conditions, termination of selling specific product, development of new product, and others through comparing and analyzing the expected risk level at the date of pricing and actual risk level after the acceptance. The Group has prepared a process to minimize management risk other than insurance actuarial risk and underwriting risk by operating a committee that shares opinions on underwriting policies and premium rate policies and decides important matters.

In addition, by establishing a reinsurance operating strategy according to the reinsurance operating standards, the Group is preparing for the possibility of incurring high claim expenses at once due to unexpected catastrophic accidents while maintaining an appropriate holding level considering the solvency of the Group. The Group supports the protection and stable interests of policyholders, and comprehensively manages risks to maximize corporate value in the mid to long term.

38.11.3 Concentration of insurance risk

The Group is selling various insurance contracts such as general non-life insurances (fire, maritime, injury, technology, liability, package, title, guarantee, and other special type insurances), automobile insurances (for private use, for business use, for commercial use, bicycle, and others), long-term insurances (long-term non-life, property damage, injury, driver, savings, illness, nursing, and pension), and others. The Group’s risk is distributed through reinsurance, joint acceptance, and sales of diversified insurance products. In addition, insurances such as storm and flood insurance, which have a very low probability of occurrence but cover severe levels of risk, are controlled through acceptance limit and joint acquisition. The Group classifies concentration of insurance risk by type of insurance product and region.

38.12 Risk Management of KB Life Insurance Co., Ltd.

38.12.1 Overview of insurance risk

Insurance risk arises from the core activities of an insurance company, particularly the underwriting of insurance contracts and the payment of claims, which may result in greater losses than the Group has anticipated.

The Group manages potential economic loss risks arising from various risk factors associated with life insurance contracts. These risks are categorized into six subcategories: mortality risk, longevity risk, disability/illness risk, termination risk, expense risk, and catastrophic risk. The Group measures these risks individually.

Except for catastrophic risk, which is assessed using a risk coefficient method, all other types of risks are evaluated using shock scenario methods. The definitions of each risks are as follows:

Mortality Risk		Risk of unexpected losses due to premature death compared to the insured’s expectations.
Longevity Risk		Risk of unexpected losses due to delayed death compared to the insured’s expectations.
Disability/Illness Risk		Risk of unexpected losses related to the insured’s disability and illness.
Termination Risk		Risk of losses due to unexpected exercise of legal rights or contractual options by policyholders.
Expense Risk		Risk of losses due to fluctuations in future costs and expenditure variations caused by inflation in relation to insurance contract costs.
Catastrophic Risk		Risk of extreme, exceptional losses (e.g., epidemics, major accidents) not considered in mortality risk, etc.

38.12.2 Management of insurance risk

The Group measures and manages insurance risk in accordance with internally developed models and the K-Insurance Capital Standard (K-ICS).

Insurance risks, excluding catastrophic risk, are managed under K-ICS, as well as being managed under IFRS 17 through sensitivity analysis.

In addition, the Group considers insurance risks inherent in insurance products during the product development stage and continues to measure and mitigate such risks through various methods after the product launch. Risks related to mortality and illness are mitigated through reinsurance. The Group selects appropriate reinsurers based on credit risk assessment and also determines the appropriate level of risk exposure for each reinsurer before making contract with reinsurers. For amounts exceeding pre-determined risk limits, the Group manages risk through facultative reinsurance.

38.12.3 Exposure by risk type

38.12.3.1 Insurance risk exposure

The Group sells life insurance products including death, health, pension, asset-linked, and variable contracts. Along with the sale of various products, the Group also diversifies risk through reinsurance cessions.

Insurance risk exposure of insurance contracts and reinsurance contracts as of December 31, 2025 and 2024, are as follows:

(In millions of Korean won)		Exposure
		December 31,2025			December 31,2024

38.12.4 Reinsurance policy

38.12.4.1 Summary

The purpose of reinsurance transactions is to ensure the Group’s ability to fulfill insurance claim obligations to policyholders and maintain the stability of the Group’s financial structure by ceding contracts that require diversification or risk transfer which could arise from the underwriting of insurance contracts. The Group adheres to the fundamental principle of operating an efficient and stable reinsurance framework by considering the scale of reinsurance transactions, the complexity of reinsurance products, risk exposure levels, profitability, and the credit ratings of reinsurers.

Based on insurance premium, since most of the retained contracts are concentrated in guarantee-type life insurance products, the Group manages insurance risk by securing reinsurance for life insurance policies exceeding a certain coverage amount. Additionally, reinsurance transactions are made when risk mitigation is deemed necessary for specific products or coverages. The Group currently holds contracts with eight reinsurers, and in addition to life insurance, risk for health insurance products such as cancer insurance are mitigated through reinsurance.

As of December 31, 2025, the eight reinsurers contracted by the Group hold credit ratings of AA- or higher, based on the criteria outlined in Annex 22 of the Korean DETAILED REGULATIONS ON SUPERVISION OF INSURANCE BUSINESS, indicating a stable financial position.

38.12.4.2 Concentration on top 5 reinsurers

38.12.5 Liquidity risk of insurance contracts

Liquidity risk in insurance contracts arises from the increase in maturity refunds due to the concentration of insurance contract maturities at a certain point in time, the excessive increase in surrender refunds due to unexpected mass surrenders, and the increase in insurance payments due to large-scale accidents. Additionally, the Group manages the payment of maturity refunds through the analysis of the maturity of insurance contracts. The maturity structure of insurance liabilities based on net cash flow as of December 31, 2025 and 2024, are as follows.

We have audited Internal Control over Financial Reporting (ICFR) of KB Financial Group Co., Ltd. and its subsidiaries (collectively referred to as the “Group”) for consolidation purposes as at December 31, 2025, based on Conceptual Framework for Designing and Operating Internal Control over Financial Reporting.

In our opinion, the Group maintained, in all material respects, effective ICFR for consolidation purposes as at December 31, 2025, based on ConceptualFramework for Designing and Operating Internal Control over Financial Reporting.

Basis for Opinion on Internal Control over Financial Reporting for Consolidation Purposes

We conducted our audit in accordance with Korean Standards on Auditing.

We are independent of the Group in accordance with the ethical requirements of the Republic of Korea that are relevant to our audit of ICFR for consolidation purposes and we have fulfilled our other ethical responsibilities in accordance with the ethical requirements.

Auditor’s Responsibilities for the Audit of Internal Control over Financial Reporting for Consolidation Purposes

Our responsibility is to express an opinion on ICFR for consolidation purposes of the Group based on our audit. We conducted the audit in accordance with Korean Standards on Auditing. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective ICFR for consolidation purposes was maintained in all material respects.

An audit of ICFR for consolidation purposes involves performing procedures to obtain audit evidence about whether a material weakness exists. The procedures selected depend on the auditor’s judgment, including the assessment of the risks that a material weakness exists. An audit includes obtaining an understanding of ICFR for consolidation purposes and testing and evaluating the design and operating effectiveness of ICFR for consolidation purposes based on the assessed risk.

Definitionand Inherent Limitations of Internal Control over Financial Reporting for Consolidation Purposes

The Group’s ICFR for consolidation purposes is a process effected by those charged with governance, management, and other personnel, designed to provide reasonable assurance regarding the preparation of reliable consolidated financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea. The Group’s ICFR for consolidation purposes 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 consolidated financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea, and that receipts and expenditures of the Group are being made only in accordance with authorizations of management and directors of the Group; 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 consolidated financial statements.

Because of its inherent limitations, ICFR for consolidation purposes 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.

The engagement partner on the audit resulting in this independent auditor’s report is Hee-Won Seo, Certified Public Accountant.

Independent Auditor’s Report

(English Translation of a Report Originally Issued in Korean)

To Shareholders and the Board of Directors of

KB Financial Group Inc.

Opinion

We have audited the accompanying separate financial statements of KB Financial Group Inc. (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 the Company 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).

We also have audited, in accordance with Korean Standards on Auditing, the Company’s Internal Control over Financial Reporting as of December 31, 2025, based onConceptual Framework for Designing and Operating Internal Control over Financial Reporting, and our report dated March 6, 2026 expressed an unqualified opinion.

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 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.

Key Audit Matters

There is no key audit matter identified to be described in this audit report.

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 financial statements may differ from those generally accepted and applied in other countries.

Responsibilities of Management and Those Charged with Governance for the 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 financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the 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 Financial Statements

Our objectives are to obtain reasonable assurance about whether the 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 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 financial statements, whether due to fraud or<br>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 higher<br>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.
---	---
•	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 financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the<br>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 financial statements, including the disclosures,<br>and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
---	---

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partner on the audit resulting in this independent auditor’s report is Hee-Won Seo, Certified Public Accountant.

The accompanying separate financial statements have been translated into English from the Korean language separate financial statements.

The separate financial statements of the Company 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 separate financial statements requires the use of certain critical accounting estimates. Management also needs to exercise judgment in applying the Company’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.

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

2.1.1 The Company has applied the following new and amended standards for the first time for its annual reporting period commencing January 1, 2025.

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

The amendments require the Company 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 another currency, the spot exchange rate(s) used, the estimation process, and the risks to which the Company is exposed. These amendments do not have a significant impact on the financial statements.

2.1.2 The following are the accounting standards that have been established or announced but have not yet been implemented, which the Company has not applied.

•	Amendment of Korean IFRS No.1109 “Financial Instruments” and No.1107 “Financial Instruments:Disclosures”

Korean IFRS No.1109 Financial Instruments and Korean IFRS No.1107 Financial Instruments:Disclosures have been amended to respond to recent questions arising in practice, and to include new requirements. The amendments should be applied for annual periods beginning on or after January 1, 2026, and earlier application is permitted. The amendments do not have a significant impact on the financial statements. These amendments:

•	clarify the date of recognition and derecognition of some financial assets and liabilities, with a new exception<br>for some financial liabilities settled through an electronic cash transfer system;
•	clarify and add further guidance for assessing whether a financial asset meets the solely payments of principal<br>and interest (SPPI) criterion;
---	---
•	add new disclosures of impact on the entity and the extent to which the entity is exposed for each type of<br>financial instruments if the timing or amount of contractual cash flow changes due to amendment of contract term; and
---	---
•	update the disclosures for equity instruments designated at fair value through other comprehensive income (FVOCI)<br>
---	---
•	Korean IFRS Accounting Standards Annual Improvements Volume 11
---	---

•	Korean IFRS No.1101 “First-time adoption of International Financial Reporting Standards”: Hedge<br>accounting by a first-time adopter
•	Korean IFRS No.1107 “Financial Instruments: Disclosures”: Gain or loss on derecognition, Application<br>guidance
---	---
•	Korean IFRS No.1109 “Financial Instruments”: Derecognition of lease liabilities, Definition of<br>transaction price
---	---
•	Korean IFRS No.1110 “Consolidated Financial Statements”: Determination of a ‘de facto<br>agent’
---	---
•	Korean IFRS No.1007 “Statement of Cash Flows”: Cost method
---	---
•	Korean IFRS No.1118 Presentation and Disclosures in Financial Statements
---	---

Korean IFRS No.1118 “Presentation and Disclosure in Financial Statements” replaces Korean IFRS No.1001 “Presentation of Financial Statements.” Korean IFRS No.1118 introduces new presentation requirements, particularly with respect to the definition of operating profit or loss, which are expected to enhance comparability of financial performance among similar entities. In addition, the disclosure requirements for management-defined performance measures are intended to improve transparency. The Standard is effective for annual reporting periods beginning on or after January 1, 2027, with early adoption permitted. In accordance with the retrospective application requirements of the Standard, the Company will restate the comparative information for the year ending December 31, 2026 in accordance with Korean IFRS No.1118.

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

The Company has not yet adopted Korean IFRS No.1118 and is currently assessing the impact that the application of the Standard will have on its financial statements. The Company has prepared a transition plan and is on track to report their first Korean IFRS No.1118-compliant interim financial statements for the period ending March 31, 2027 and annual financial statements for the period ending December 31, 2027.

2.2 Measurement Basis

The separate financial statements have been prepared under the historical cost convention unless otherwise specified.

2.3 Functional and Presentation Currency

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

December31, 202 5 and 202 4

2.4 Critical Accounting Estimates

The Company applies accounting policies and uses judgements, 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.

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 Company’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

As described in the significant accounting policies in Note 3.1 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.

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

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 Recognition and Measurement of Financial Instruments

3.1.1 Initial recognition

The Company recognizes a financial asset or a financial liability in its statement of financial position when the Company 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 Company 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.

3.1.2 Subsequent measurement

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

3.1.2.1 Amortized cost

3.1.2.2 Fair value

The Company 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.

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.1.2.2 Fair value (cont’d)

The Company uses valuation models that are commonly used by market participants and customized for the Company 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 Company 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 Company can access at<br>the measurement date
Level 2:	Inputs other than quoted prices included within Level 1 that are observable for the asset or liability,<br>either directly or indirectly
---	---
Level 3:	Unobservable inputs for the asset or liability
---	---

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

The Company uses 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 Company 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.

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

3.1.3 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:

3.1.3.1 Derecognition of financial assets

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

If the Company 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 Company continues to recognize the transferred asset in its entirety and recognize a financial liability for the consideration received.

The Company writes off a financial asset when the Company has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. In general, the Company 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 regulations. After the write-off, the Company can collect the written-off loans continuously according to the internal policy. Recovered amounts from financial assets previously written-off are recognized in profit or loss.

3.1.3.2 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).

3.1.4 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 Company currently has a legally enforceable right to set off 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 Company and all of the counterparties.

3.2 Cash and Due from Financial Institutions

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

3.3 Non-derivative Financial Assets

3.3.1 Financial assets at fair value through profit or loss

The Company 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.

3.3.2 Financial assets at fair value through other comprehensive income

The Company 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<br>cash flows and selling financial assets, and where the assets’ cash flows represent solely 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<br>financial assets at fair value through other comprehensive income
---	---

3.3.3 Financial assets at amortized cost

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

3.4 Expected Credit Losses of Financial Assets (Debt Instruments)

The Company 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 Company 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 2 approaches<br>
•	Simplified approach: for trade receivables, contract assets, and lease receivables
---	---
•	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 Company 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 Company 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 Company 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 Company 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
---	---
•	Debt restructuring (except for impaired financial assets) and
---	---
•	Credit delinquency information of Korea Credit Information Services, etc.
---	---

Under simplified approach, the Company always measures loss allowances at an amount equal to lifetime expected credit losses. Under credit-impaired approach, the Company only recognizes the cumulative changes in lifetime expected credit losses since initial recognition as loss allowances at the end of the reporting period.

The Company generally considers the loan to be credit-impaired if one or more of the following criteria are met:

•	90 days or more past due
•	Legal proceedings related to collection
---	---
•	A borrower registered on the credit management list of Korea Federation of Banks
---	---
•	A corporate borrower with the credit rating C and D
---	---
•	Debt restructuring, etc.
---	---

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

3.4.1 Forward-looking information

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

The Company 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 Company 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 macroeconomic<br><br><br>variables and the credit risk
Benchmark interest rate		(+)
AA- rated corporate bond<br>(3-year)		(+)
BBB- rated corporate bond<br>(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 Company 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 Company 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 Company measured expected credit losses by incorporating both the worsening and crisis macroeconomic scenarios, taking into account potential credit risks arising from the uncertain domestic and global financial environment and the sharp economic downturn.

3.4.2 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 Company estimates expected future cash flows for financial assets that are individually significant. The Company selects the individually significant financial assets by comprehensively considering quantitative and qualitative factors (such as debt restructuring or negative net assets, etc.) among financial assets with the credit risk has increased significantly or credit-impaired (individual assessment of impairment).

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

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

3.4.2.1 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 Company uses all the available information including financial condition of the borrower such as operating cash flow and net realizable value of any collateral held.

3.4.2.2 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 Company 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.

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

The Company 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.

3.5 Revenue Recognition

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

•	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.
---	---

3.5.1 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 securities), 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.

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.5.1 Interest income and expense (cont’d)

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 Company 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 Company 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 statement of comprehensive income.

3.5.2 Fee and commission income

The Company 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.

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

3.5.2.2 Fees related to performance obligations satisfied over time

If the control of a good or service is transferred over time, the Company 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.

3.5.2.3 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 controls of a promised good or service and the Company satisfies a performance obligation.

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

3.5.4 Dividend income

3.6Investments in Subsidiaries and Associates

Investments in subsidiaries and associates are accounted at cost method in accordance with Korean IFRS No.1027. The Company determines at each reporting period whether there is any objective evidence that the investments in the subsidiaries and associates are impaired. If this is the case, the Company calculates the amount of impairment as the difference between the recoverable amount of the subsidiaries or associates and its carrying value.

3.7 Property and Equipment

3.7.1 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.

3.7.2 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 Company. 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.

3.7.2 Depreciation (cont’d)

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

Property and equipment		Depreciation method		Estimated useful life
Leasehold improvements<br><br><br>Equipment and vehicles		Declining-balance<br><br><br>Declining-balance		4 years<br><br><br>4 years

3.8 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 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
Software		Straight-line		4 years
Others		Straight-line		4 ~ 19 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 Company 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.

3.9 Impairment of Non-financial Assets

The Company 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 Company estimates the recoverable amount of the asset.

The recoverable amount is estimated for the individual asset. If it is not possible to estimate the recoverable amount of the individual asset, the Company 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.

3.10 Provisions

Provisions are recognized when the Company 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.

3.11 Equity Instrument Issued by theCompany

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.

3.11.1 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.

3.11.2 Hybrid securities

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

3.11.3 Treasury shares

If the Company acquires its own equity instruments, these are accounted for as treasury shares and are deducted directly from equity. No gains or losses are recognized in profit or loss on the purchase, sale, issue or retirement of own equity instruments.

3.12 Employee Compensation and Benefits

3.12.1 Post-employment benefits

3.12.1.1 Defined contribution plans

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

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 202 5 and 202 4

3.12.1.2 Defined benefit plans

The present value of the defined benefit obligation is calculated annually by independent actuaries 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 resulted from changes in actuarial assumptions and experience adjustments are recognized in other comprehensive income.

3.12.2 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 Company during an accounting period, the Company 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 Company 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.

3.12.3 Share-based payment

The Company provides stock grants program to executives and employees of the Company and its subsidiaries. When stock grants are exercised, the Company can either select to distribute newly issued shares or treasury shares or compensate in cash based on the share price.

For a share-based payment transaction in which the terms of the arrangement provide the Company with the choice of whether to settle in cash or by issuing equity instruments, the Company accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions because the Company 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 Company measures the liability incurred as consideration for the service received at fair value and recognizes related expense and accrued expense over the vesting periods. Until the liability is settled, the Company 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.

3.12.4 Termination benefits

Termination benefits are payable when employment is terminated by the Company before the normal retirement date, or an employee’s decision to accept an offer of benefits in exchange for the termination of employment. The Company recognizes a liability and expense for termination benefits at the earlier of the following dates; when the Company can no longer withdraw the offer of those benefits and when the Company 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.

3.13 Income Tax Expense

3.13.1 Current income tax

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

3.13.2 Deferred income tax

The carrying amount of a deferred income tax asset is reviewed at the end of each reporting period. The Company 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.

KB Financial Group Inc.

Notes to the Separate Financial Statements

December31, 2025 and 2024

3.13.2 Deferred income tax (cont’d)

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 Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

The Company offsets deferred income tax assets and deferred income tax liabilities if, and only if the Company has a legally enforceable right to set off 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.

3.13.3 Uncertain tax positions

Uncertain tax positions arise from tax treatments applied by the Company 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 Company 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.

3.14 Earnings per Share

The Company calculates basic earnings per share amounts and diluted earnings per share amounts for profit or loss for the period and presents them in the statement of comprehensive income. Basic earnings per share is calculated by dividing profit or loss attributable to ordinary equity holders of the Company by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per share is calculated by adjusting the profit or loss attributable to ordinary equity holders of the Parent Company and weighted average number of shares outstanding, taking into account all potential dilution effects, such as exchangeable bonds and share-based payments given to employees.

3.15 Leases

The Company 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 Company 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 $ 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 Company 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.

4.3 Liquidity Risk

4.3.1 Overview of liquidity risk

Liquidity risk is a risk that the Company 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 Company manages its liquidity risk through analysis of the contractual maturity of all financial assets and liabilities and discloses in six categories such as on demand, less than one month, between one month to three months, between three months to one year, between one year to five years, and over five years.

4.3.2. Liquidity risk management

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 for 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. The Company 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 Trading position

In accordance with Financial Holding Companies Act, the Company’s main business is to control financial companies or companies closely related to the financial service. And the Company cannot perform any other business other than managing activities as a holding company, therefore there is no risk of trading position.

4.4.3 Non-trading position

Non-trading position refers to the part except trading position, and the main risk the Company is managing is interest rate risk.

4.4.3.1 Interest rate risk

(a) Definition of interest rate risk

Interest rate risk refers to the risk of changes in the value (fair value) of the items in the statement of financial position due to changes in interest rate and the risk of changes in cash flows related to interest income and interest expense arising from investment and financing activities.

(b) Observation method and management indicator on interest rate risk

The main objective of interest rate risk management is to protect the value changes from interest rate fluctuations. The Company applies the Interest Rate Risk in the Banking Book (“IRRBB”) standard methodology required for disclosure to measure interest rate risk.

ΔEVE means changes in equity and earnings due to the changes in value of interest-sensitive assets and liabilities, etc. when interest rate changes, and ΔNII means changes in net interest income. The Company calculates ΔEVE by applying following six interest rate shock and stress scenarios, and ΔNII by applying parallel shock up and parallel shock down scenarios. The interest rate risk for the interest rate shock and stress scenario is calculated only when the risk for each scenario is a loss.

•	Scenario 1 : Parallel shock up
•	Scenario 2 : Parallel shock down
---	---
•	Scenario 3 : Steepener shock (short rates down and long rates up)
---	---

4.5 Capital Management

The Company as a financial holding company under the Financial Holding Companies Act, complies with the consolidated 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 9.0%, Tier 1 Capital ratio of 10.5%, and Total Capital ratio of 12.5%) as of December 31, 2025.

The Group’s capital is classified into three categories in accordance with the Detailed Regulations on Supervision of Financial Holding Companies 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 meets 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 Financial Holding Companies, and others.
---	---

The Group evaluates and manages capital adequacy through separate 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.

Internal capital refers to the capital required to prevent the Group’s insolvency from future unexpected losses. The Group operates a system to measure, allocate and manage internal capital to major subsidiaries by risk type.

4.5 Capital Management (cont’d)

The Risk Management Committee of the Company determines the risk appetite of the Group, allocates internal capital by risk type and major subsidiaries, and major subsidiaries operate 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 due to new businesses or business expansion, the Group’s capital adequacy management is carried out through review and approval by the Risk Management Committee in advance.

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

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 Company 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 quoted price in an active market.

5.1.1 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<br> <br>financialinstitutions		Fair value of cash is same as 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 receivable<br>on demand. Fair value of general deposit is measured using Discounted Cash Flow (“DCF”) Model.
Securities		Fair value of financial instruments that are quoted in an active market is determined using the quoted prices. If there is no quoted price, fair value is determined using external professional valuation institutions. The<br>institutions use one or more valuation techniques that are deemed appropriate considering the characteristics of the financial instruments among DCF Model, Imputed Market Value Model, Free Cash Flow to Equity Model, Dividend Discount Model, Risk<br>Adjusted Discount Rate Method, and Net Asset Value Method.
Derivatives		Fair value of exchange traded derivatives is determined using quoted price in an active market, and fair value of OTC derivatives is determined using valuation techniques. The Company 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 the Finite Difference Method (“FDM”), and the MonteCarlo Simulation or valuation results from independent external professional valuation<br>institution.
Loans		Fair value of loans is determined using DCF model discounting the expected cash flows, which are contractual cash flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Borrowings		DCF model is used to determine the fair value of borrowings, but in the case of short-term maturity, carrying amount is a reasonable approximation of fair value.
Debentures		Fair value is determined by using valuation results of external professional valuation institutions, which are calculated using market inputs.
Other financial assets<br> <br>andother financial<br> <br>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.

5.1.2 Fair value hierarchy

The Company believes that valuation techniques used for measuring the fair value of financial instruments are reasonable and that the fair value recognized in the statements of financial position is appropriate. However, the fair value of the financial instruments recognized in the statements 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 Company 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.

17. Net Defined Benefit Liabilities(Assets)

17.1 Defined Benefit Plan

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

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

The net defined benefit liabilities recognized in the statements of financial position are calculated in accordance with 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.

Diluted earnings per share is calculated through increasing the weighted average number of ordinary shares outstanding by the weighted average number of additional ordinary shares that would have been outstanding assuming the conversion of all dilutive potential ordinary shares. The Company has dilutive potential ordinary shares such as stock grants and ordinary share exchange right of exchangeable bonds.

A calculation is being made to determine the number of shares that could have been acquired at fair value (determined as the average market share price for the year) based on the monetary value of stock grants. The number of shares calculated above is compared with the number of shares that would have been issued assuming the settlement of stock grants.

Independent Auditor’s Report on

Internal Control over Financial Reporting

(English Translation of a Report Originally Issued in Korean)

To Shareholders and the Board of Directors of KB Financial Group Inc.

Opinion on Internal Control over Financial Reporting

We have audited KB Financial Group Inc.’s (the Company) Internal Control over Financial Reporting as at December 31, 2025, based on Conceptual Framework for Designing and Operating Internal Control over Financial Reporting.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as at December 31, 2025, based on Conceptual Framework for Designing and Operating Internal Control over Financial Reporting.

We also have audited, in accordance with Korean Standards on Auditing, the separate financial statements of the Company, which comprise the separate statement of financial position as at December 31, 2025, and the separate statement of comprehensive income, separate statement of changes in equity and separate statement of cash flow for the year then ended, and notes to the separate financial statements including material accounting policy information, and our report dated March 6, 2026 expressed an unqualified opinion.

Basis for Opinion on Internal Control over Financial Reporting

We conducted our audit in accordance with Korean Standards on Auditing. Our responsibility under these standards are further described in the Auditor’s Responsibilities for the Audit of Internal Control over Financial Reporting 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 internal control over financial reporting 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.

Responsibilities of Management and Those Charged with Governance for Internal Control over Financial Reporting

Management is responsible for designing, implementing and maintaining effective internal control over financial reporting, and for its assessment about the effectiveness of internal control over financial reporting, included in the accompanying ‘Operating Status Report of Internal Control over Financial Reporting’.

Those charged with governance have the responsibilities for overseeing internal control over financial reporting.

Auditor’s Responsibilities for the Audit of Internal Control over Financial Reporting

Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted the audit in accordance with Korean Standards on Auditing. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

An audit of internal control over financial reporting involves performing procedures to obtain audit evidence about whether a material weakness exists. The procedures selected depend on the auditor’s judgment, including the assessment of the risks that a material weakness exists. An audit includes obtaining an understanding of internal control over financial reporting and testing and evaluating the design and operating effectiveness of internal control over financial reporting based on the assessed risk.

Definition and Inherent Limitations of Internal Control over Financial Reporting

An entity’s internal control over financial reporting 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. An entity’s internal control over financial reporting 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, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and those charged with governance; 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, internal control over financial reporting 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.

The engagement partner on the audit resulting in this independent auditor’s report is Hee-Won Seo, Certified Public Accountant.
