1.5.	Dividends

On October 24, 2024, KB Financial Group disclosed a detailed plan to enhance corporate value titled “KB Financial Group’s Sustainable Value-up Plan,” which includes information on shareholder returns and dividends. The key details of the plan are as outlined below (the full version of the plan can be accessed on KB Financial Group’s website at www.kbfg.com).

The Company’s goal is to maintain a target ROE of 10% or above, as it strives to improve profitability by enhancing its RoRWA, thereby strengthening its intrinsic corporate value.

The Company also seeks to maintain a target CET1 ratio of 13% or above. It aims to carefully manage its RWA growth rate by taking capital efficiency and profitability into consideration with the goal of maintaining a CET1 ratio in the range of mid-13% throughout the year.

The Company plans to execute its shareholder return policy in two phases. In the first phase, it will aim to utilize the capital in such amount that is equivalent to the amount exceeding 13% of its CET1 ratio as of the end of the previous year for the payment of shareholder returns in the following year. These returns will be supported through quarterly cash dividends (equitably distributed on a total annual basis) and through share buybacks and cancellations. In the second phase, the Company will aim to utilize the capital in such amount that is equivalent to the amount exceeding 13.5% of its CET1 ratio in the second half of the year to pay for additional shareholder returns. These returns, which will be made based on profits accumulated throughout the year, will be executed through share buybacks and cancellations.

These goals and expectations are subject to adjustments based on economic uncertainties, regulatory considerations, capital ratio projections, and the Company’s strategic objectives, including potential inorganic growth opportunities.

KB Financial Group’s progress report on its Sustainable Value-up Plan is available on its website (www.kbfg.com).

2.3.5. Other Factors Affecting the Group’s Financial Condition and Results of Operations

The economic outlook for Korea and its financial services sector in the remainder of 2026 and for the foreseeable future remains highly uncertain as a result of, among others, (i) volatile conditions in the Korean and global economies and financial markets resulting from interest and exchange rate fluctuations, a slowdown in the rate of economic growth, high levels of inflation as a result of increases in the price of energy, subdued domestic consumption, stock market and real estate market volatility, rising loan delinquency rates in Korea and changes in fiscal and monetary policies, among others, and (ii) adverse conditions in the Korean and global economies and financial markets resulting from geopolitical uncertainties, including as a result of the imposition of significant tariffs by the United States on its trading partners and other escalations in trade protectionism globally, changes in the global policies of the United States, the ongoing military conflicts in the Middle East (between Iran and other countries, including the United States and Israel), among others.

Report on Review of Condensed Consolidated InterimFinancial Statements

(English Translation of a Report Originally Issued in Korean)

To the Shareholders and the Board of Directors of

KB Financial Group Inc.

Reviewed Financial Statements

We have reviewed the accompanying condensed consolidated interim financial statements of KB Financial Group Inc. and its subsidiaries (collectively referred to as the “Group”). These condensed consolidated interim financial statements consist of the consolidated interim statement of financial position of the Group as at March 31, 2026, and the related consolidated interim statements of comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2026 and 2025, and material accounting policy information and other selected explanatory notes, expressed in Korean won.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and presentation of these condensed consolidated interim financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”) 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of condensed consolidated interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express a conclusion on these condensed consolidated interim financial statements based on our review.

We conducted our review in accordance with quarterly or semi-annual review standards established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe the accompanying condensed consolidated interim financial statements are not prepared, in all material respects, in accordance with Korean IFRS 1034 Interim FinancialReporting.

Other Matters

We have audited the consolidated statement of financial position of the Group as at December 31, 2025, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, not presented herein, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those financial statements in our audit report dated March 6, 2026. The consolidated statement of financial position as at December 31, 2025, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2025.

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

This report is effective as of May 15, 2026, the review report date. Certain subsequent events or circumstances, which may occur between the review report date and the time of reading this report, could have a material impact on the accompanying condensed consolidated interim financial statements and notes thereto. Accordingly, the readers of the review report should understand that there is a possibility that the above review report may have to be revised to reflect the impact of such subsequent events or circumstances, if any.

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.

The Group’s condensed consolidated interim financial statements for the three-month period ended March 31, 2026, have been prepared in accordance with Korean IFRS No.1034 Interim Financial Reporting and contain less information than is required in annual consolidated financial statements. Selected explanatory notes include descriptions of transactions or events that are significant in understanding change in financial position and financial performance of the Group since the end of the previous annual reporting period. These consolidated interim financial statements have been prepared in accordance with Korean IFRS which is effective or early adopted as of March 31, 2026.

2.1.1 The Group has applied the following standards and amendments for the first time for their annual reporting period commencing January 1, 2026.

•	Amendments to Korean IFRS No.1109 Financial Instruments, Korean IFRS No.1107 Financial Instruments:Disclosures

These 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>
---	---

Notes to the Consolidated Interim Financial Statements

March 31, 2026 and 2025 (Unaudited), and December 31, 2025

•	Annual Improvements to Korean IFRS - Volume 11

Annual Improvements to Korean IFRS - Volume 11 should be applied for annual periods beginning on or after January 1, 2026. These amendments do not have a significant impact on the financial statements.

•	Korean IFRS No.1101 First-time Adoption of International Financial Reporting Standards: Hedge accounting by afirst-time adopter
•	Korean IFRS No.1107 Financial Instruments: Disclosures: Gain or loss on derecognition and implementationguidance
---	---
•	Korean IFRS No.1109 Financial Instruments: Derecognition of lease liabilities and definition of transactionprice
---	---
•	Korean IFRS No.1110 Consolidated Financial Statements: Determination of a ‘de facto agent’<br>
---	---
•	Korean IFRS No.1007 Statement of Cash Flows: Cost method
---	---

2.1.2 The following are the accounting standards that have been issued but were not mandatory for annual reporting periods ending on December 31, 2026.

•	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 is expected to enhance the comparability of financial performance among similar entities by providing users with more useful information for analyzing and comparing an entity’s performance based on the income statement.

When the Group prepares its financial statements by applying Korean IFRS No.1118, the following material accounting policies are expected to result in significant differences compared to the current financial statements. These items do not include all potential differences and may be subject to change based on further analysis.

•	Changes in the presentation of the income statement

Korean IFRS No.1118 requires all income and expenses included in the statement of profit or loss to be classified into one of five categories: operating, investing, financing, income taxes, and discontinued operations. The Standard classifies all income and expenses not attributable to the investing, financing, income tax, or discontinued operations categories as operating and defines operating profit or loss as a residual measure. The Group is required to assess its main business activities in determining the classification of income and expenses. Where the Group’s main business activities include investing in a particular type of asset or providing financing to customers, certain income and expenses that would otherwise be classified as investing or financing are classified as operating. Accordingly, operating profit or loss determined under Korean IFRS No.1118 may differ significantly from that determined under Korean IFRS No.1001.The Standard requires the disclosure, in the notes, of operating profit or loss determined in accordance with Korean IFRS No.1001, as well as a reconciliation between operating profit or loss under Korean IFRS No.1118 and that determined in accordance with Korean IFRS No.1001.

In addition, Korean IFRS No.1118 requires the presentation in the statement of profit or loss of “operating profit or loss,” comprising all income and expenses classified in the operating category; “profit or loss before financing and income taxes,” comprising operating profit or loss and all income and expenses classified in the investing category; and “profit or loss.” However, where the Group’s main business activities include providing financing to customers, the presentation of “profit or loss before financing and income taxes” may not be required, depending on the accounting policy applied.

Notes to the Consolidated Interim Financial Statements

March 31, 2026 and 2025 (Unaudited), and December 31, 2025

•	Introduction of disclosure of management-defined performance measures

Korean IFRS No.1118 introduces new disclosure requirements for management-defined performance measures (MPMs). MPMs are defined as subtotals of income and expenses that are not specified in paragraph 118 of the Standard and are not otherwise required to be presented or disclosed under Korean IFRS. These measures are used by an entity in public communications outside the financial statements and are intended to communicate management’s view of the entity’s financial performance to users of the financial statements.

When the Group reports MPMs, it is required to disclose the reasons why such measures provide useful information, how those measures are calculated, and a reconciliation between those measures and the most directly comparable subtotal specified in Korean IFRS No.1118. In addition, the Group is required to disclose the income tax effects and the effects on non-controlling interests for each reconciling item.

•	Changes in classification of cash flows

Consequential amendments have been made to Korean IFRS No.1007 “Statement of Cash Flows” following the issuance of Korean IFRS No.1118. Under these amendments, the starting point for determining cash flows from operating activities using the indirect method has been changed from profit or loss to operating profit or loss, and the accounting policy choice for the classification of interest and dividends has been eliminated.

Korean IFRS No.1118 is effective for annual reporting periods beginning on or after January 1, 2027, with early adoption permitted. In accordance with Korean IFRS No.1008 “Accounting Policies, Changes in Accounting Estimates and Errors,” the Standard is required to be applied retrospectively, and accordingly, the comparative information for the year ending December 31, 2026 will be restated. The amendments to Korean IFRS No.1007 and No.1033, as well as the revised Korean IFRS No.1008 and No.1107 resulting from the issuance of Korean IFRS No.1118, are effective when Korean IFRS No.1118 is applied.

As the mandatory effective date of Korean IFRS No.1118 has not yet been reached, the Group has not applied the Standard and plans to present its first interim financial statements for the period ending March 31, 2027 in accordance with Korean IFRS No.1118. Based on the information available as of March 31, 2026, the Group is in the process of assessing the financial impact of adopting Korean IFRS No.1118, establishing accounting policies, and implementing changes to its accounting systems, and is performing a preliminary overall assessment of the impact of applying the Standard.

2.2 Measurement Basis

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

2.3 Functional and Presentation Currency

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

March 31, 2026 and 2025 (Unaudited), and December 31, 2025

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). Management’s estimates of outcomes may differ from actual outcomes if management’s estimates and assumptions based on management’s best judgment at the reporting date 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 used in the preparation of these condensed consolidated interim financial statements are the same as those applied to the consolidated financial statements for the year ended December 31, 2025.

3. Material Accounting Policies

The material accounting policies and calculation methods applied in the preparation of these consolidated interim financial statements are the same as those applied to the consolidated financial statements for the year ended December 31, 2025, except for the impact of changes due to adopting new and amended standards and interpretations described in Note 2.1 and below paragraph.

The Group is subject to Pillar 2 income taxes, and has applied a temporary exemption provision regarding the recognition and disclosure of deferred taxes related to the Pillar 2 rules.

Income tax expense for the interim period is measured applying the expected average annual income tax rate applicable on expected total annual income.

4.Financial Risk Management

4.1 Summary

4.1.1 Overview of financial risk management policy

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

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

The Group’s risk management system focuses on efficiently supporting long-term strategy and management decisions of the Group by increasing risk transparency, preventing risk transfer between subsidiaries and preemptive response to rapidly changing financial environments.

4.1.2 Risk management organization

4.1.2.1 Risk Management Committee

The Risk Management Committee, as the ultimate decision-making body, deals with risk-related issues, such as establishing risk management strategies in accordance with the strategic direction determined by the board of directors, determining the affordable level of risk appetite, reviewing the level of risk and the status of risk management activities, approving the application of risk management systems, methodologies, and major improvements, and establishing and approving risk management strategies and procedures to timely recognize, measure, monitor, and control risks arising from various transactions by the Group.

4.1.2.2 Risk Management Council

The Risk Management Council is responsible for consulting on matters delegated by the Risk Management Committee and requests for review by the Management Executive Committee, consulting on details of each subsidiary’s risk management strategies and procedures, monitoring the Group’s risk management status, and establishing and implementing necessary measures.

4.1.2.3 Risk Management Department

The Risk Management Department performs the Group’s risk management detailed strategies, procedures, and business processes, and is responsible for calculating the Group’s risk-weighted assets, monitoring and managing internal capital limits.

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 internal 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 internal capital limits.

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

All of the 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.

Notes to the Consolidated Interim Financial Statements

March 31, 2026 and 2025 (Unaudited), and December 31, 2025

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 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 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 (“

LOGO EVE”), changes in Net Interest Income (“

LOGO NII”), and duration gap to the ALCO and the Risk Management Council on a monthly basis, and to the Risk Management Committee on a quarterly basis. To ensure the adequacy of interest rate risk and liquidity risk management, the Risk Management Department assigns the limits, monitors and reviews the procedures and tasks of ALM operations conducted by the ALM department, and reports related matters to the management independently.

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.

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 March 31, 2026 and December 31, 2025, 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<br>receivable on demand. Fair value of general deposit is measured using Discounted Cash Flow (“DCF”) Model.
Securities	Fair value of listed stocks 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”), MonteCarlo Simulation, Black-Scholes Model, Hull-White Model, Closed Form, and Tree Model or valuation results<br>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<br>expected 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<br>not 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 Disclosure of Fair Value Hierarchy Level 3

6.2.1 Valuation policy and process of Level 3 fair value

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

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

6.2.3.2 Sensitivity analysis of changes in unobservable inputs

Sensitivity analysis of financial instruments is performed to measure favorable and unfavorable changes in fair value of financial instruments which are affected by unobservable parameters, using a statistical technique. When the fair value is affected by more than one input parameter, the amounts represent the most favorable or most unfavorable outcome. Level 3 financial instruments subject to sensitivity analysis are (a) loans, 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, 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 March 31, 2026 and December 31, 2025, are as follows:

6.2.4 Valuation gains and losses on transaction day

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 valuation gains and losses on transaction day for the three-month periods ended March 31, 2026 and 2025, are as follows:

(In millions of Korean won)	2026			2025
Balance at the beginning of the period	~~W~~	32,734		~~W~~	12,140

8. 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”)

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.

18.1 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.

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.

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 during the period) 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.

If Kookmin Bank does not exercise the call option during the exercise period, STIC holds a put option to sell the shares to Kookmin Bank within one year following the expiration of the call option period.

i) As of March 31, 2026, KB Real Estate Trust Co., Ltd. may lend up to ~~W~~ 4,323,000 million to trust accounts, which represents a portion of the total project cost related to borrowing-type land trust contracts (including maintenance and redevelopment projects). Whether KB Real Estate Trust Co., Ltd. provides such trust account loans does not constitute an unconditional payment obligation and is determined after comprehensively considering various factors, including the funding plan of its own accounts and the cash flow projections of the trust business.

j) On July 1, 2025, Kookmin Bank entered into a share purchase agreement with a third party for the sale of its equity interest in its subsidiary, PT KB Bukopin Finance, and is currently in the process of carrying out the procedures necessary to complete the disposal. Upon completion of the transaction as planned, Kookmin Bank will lose control over PT KB Bukopin Finance.

k) As of March 31, 2026, KB Capital Co., Ltd. is currently undergoing a tax audit for the fiscal years 2022 through 2024 by the tax authorities. The outcome of the tax audit cannot be predicted at this time.

2.1.1 The Company has applied the following standards and amendments for the first time for their annual reporting period commencing January 1, 2026.

•	Amendments to Korean IFRS No.1109 Financial Instruments, Korean IFRS 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. These amendments do not have a significant impact on the financial statements. These amendments:

Notes to the Separate Interim Financial Statements

March 31, 2026 and 2025 (Unaudited), and December 31, 2025

2.1.2 The following are the accounting standards that have been issued but were not mandatory for annual reporting periods ending on December 31, 2026 (cont’d)

•	Changes in the presentation of the income statement

Korean IFRS No.1118 requires all income and expenses included in the statement of profit or loss to be classified into one of five categories: operating, investing, financing, income taxes, and discontinued operations. The Standard classifies all income and expenses not attributable to the investing, financing, income tax, or discontinued operations categories as operating and defines operating profit or loss as a residual measure. The Company is required to assess its main business activities in determining the classification of income and expenses. Where the Company’s main business activities include investing in a particular type of asset or providing financing to customers, certain income and expenses that would otherwise be classified as investing or financing are classified as operating. Accordingly, operating profit or loss determined under Korean IFRS No.1118 may differ significantly from that determined under Korean IFRS No.1001.The Standard requires the disclosure, in the notes, of operating profit or loss determined in accordance with Korean IFRS No.1001, as well as a reconciliation between operating profit or loss under Korean IFRS No.1118 and that determined in accordance with Korean IFRS No.1001.

In addition, Korean IFRS No.1118 requires the presentation in the statement of profit or loss of “operating profit or loss,” comprising all income and expenses classified in the operating category; “profit or loss before financing and income taxes,” comprising operating profit or loss and all income and expenses classified in the investing category; and “profit or loss.” However, where the Company’s main business activities include providing financing to customers, the presentation of “profit or loss before financing and income taxes” may not be required, depending on the accounting policy applied.

•	Introduction of disclosure of management-defined performance measures

When the Company reports MPMs, it is required to disclose the reasons why such measures provide useful information, how those measures are calculated, and a reconciliation between those measures and the most directly comparable subtotal specified in Korean IFRS No.1118. In addition, the Company is required to disclose the income tax effects and the effects on non-controlling interests for each reconciling item.

•	Changes in classification of cash flows

2.1.2 The following are the accounting standards that have been established or announced but have not yet been implemented, which the Group has not applied (cont’d)

As the mandatory effective date of Korean IFRS No.1118 has not yet been reached, the Company has not applied the Standard and plans to present its first interim financial statements for the period ending March 31, 2027 in accordance with Korean IFRS No.1118. Based on the information available as of March 31, 2026, the Company is in the process of assessing the financial impact of adopting Korean IFRS No.1118, establishing accounting policies, and implementing changes to its accounting systems, and is performing a preliminary overall assessment of the impact of applying the Standard.

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.

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 used in the preparation of these condensed separate interim financial statements are the same as 2025 financial statements, except for the method of estimating income tax expense.

3. MaterialAccounting Policies

The material accounting policies and calculation methods applied in the preparation of these condensed separate interim financial statements are the same as those applied to the separate financial statements for the year ended December 31, 2025, except for the impact of changes due to adopting new and amended standards and interpretations described in Note 2.1 and below paragraph.

The Company is subject to Pillar 2 income taxes, and has applied a temporary exemption provision regarding the recognition and disclosure of deferred taxes related to the Pillar 2 rules.

Income tax expense for the interim period is measured applying the expected average annual income tax rate applicable on expected total annual income.

4.2.4 Credit risk of loans

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

The Company 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 Company measures the expected credit losses on 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 financial statements.

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.

Remaining contractual maturity of financial liabilities as of March 31, 2026 and December 31 2025, are as follows:

	March 31, 2026

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. In addition to the Interest Rate Risk in the Banking Book (“IRRBB”) standard methodology required for disclosure to measure interest rate risk.

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 March 31, 2026 and December 31, 2025, 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 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 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.

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.

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.
