IFRS Accounting Standards financial

"summary of the Company’s consolidated financial information under IFRS Accounting Standards as issued"

International Financial Reporting Standards (IFRS) are a set of common rules for preparing company financial reports so numbers like profit, assets and debt are presented consistently across countries. Think of them as a standardized recipe or blueprint that helps investors compare businesses the same way they would compare cars using the same list of features; consistent reporting reduces surprises and makes it easier to assess value, risk and performance.

Japanese GAAP financial

"Reconciliation with Japanese GAAP is provided, including total equity and net profit differences"

Derivative financial instruments financial

"Differences arising from different accounting for: 2. Derivative financial instruments"

Derivative financial instruments are contracts whose value is tied to the price of something else — for example a stock, bond, commodity or market index — much like an insurance policy or a bet tied to the outcome of an event. They matter to investors because they can be used to reduce risk, amplify returns or speculate on price moves, but they can also magnify losses and affect a company’s financial exposure and market volatility.

Defined benefit plans financial

"Defined benefit plans (Item 8) (Calculation of discount rate and net interest)"

A defined benefit plan is a retirement program that promises employees a specific, often lifetime, payment in retirement based on salary and years of service — like a guaranteed pension check rather than a personal savings pot. It matters to investors because the employer must fund and report the long-term obligation; shortfalls, higher funding costs or rising pension liabilities can reduce cash available for business use, earnings and credit strength.

A brief explanation of adjustments with significant impacts arising from differences in equity and/or net profit between Japanese GAAP and IFRS is provided below. For a more detailed explanation, please refer to “Item 5. Operating and Financial Review and Prospects – Reconciliation with Japanese GAAP” in the annual report on Form 20-F filed on June 26, 2026 (Eastern Daylight Time).

Scope of Consolidation (Item 1)

• Under IFRS, the Group consolidates an entity when it “controls” the entity. In general, the Group considers that it controls an entity when it has the existing rights that give it the current ability to direct the operating and financing policies by owning more than half of the voting power, or by legal or contractual arrangements.

• All types of entities, irrespective of their purpose or legal form, are consolidated under IFRS when the substance of the relationship between the entities and the Group indicates that the entities are controlled by the Group. Therefore, certain entities such as securitization vehicles which are not consolidated under Japanese GAAP are consolidated under IFRS.

- 5 -

Derivative financial instruments (Item 2)

(Hedge accounting)

• The Group applies hedge accounting under Japanese GAAP. However, the qualifying criteria for certain hedge accounting under IFRS are more rigorous than those under Japanese GAAP. Therefore, except for fair value hedge accounting and hedge accounting for net investments in foreign operations the Group applies under IFRS, the effects of hedge accounting under Japanese GAAP have been reversed under IFRS.

Investment securities (Item 3)

(Fair value measurement of investment securities)

• Under Japanese GAAP, stocks and financial instruments similar to stocks that are not traded in an active market, such as unlisted stocks, are measured at cost if they are classified as available-for-sale, whereas, under IFRS, those are measured at fair values determined by using valuation techniques.

(Changes in fair value of investment securities)

• Under Japanese GAAP, the changes in fair value of available-for-sale financial assets are recognized in other comprehensive income and subsequently transferred to profit or loss on their disposal. Under IFRS, the Group made an irrevocable election for some equity instruments to present subsequent changes in fair value in other comprehensive income. The changes in fair value of those equity instruments presented in other comprehensive income are not subsequently transferred to profit or loss.

• Some available-for-sale financial assets under Japanese GAAP, including investment funds, are classified as financial assets measured at fair value through profit or loss, and therefore the changes in their fair values are recognized in profit or loss under IFRS.

Loans and advances (Item 4)

(Impairment of loans and advances)

• Under Japanese GAAP, the allowance for loan losses is calculated based on credit assessments at the end of the reporting period. A collective allowance is calculated using historical loss experience based on historical results according to the obligor grade, adding forward looking information as appropriate. The allowance for specifically identified significant loans is calculated by the discounted cash flow (“DCF”) method, which is based on the present value of reasonably estimated cash flows discounted at the original contractual interest rate of the relevant loan. For the remaining loans, an individual allowance is calculated based on the estimated uncollectible amount considering historical loss experience and the recoveries from collateral, guarantees and any other collectible cash flows.

• Under IFRS, measurement of expected credit losses (“ECL”) depends on whether the credit risk on the financial asset has increased significantly since initial recognition. If there is not a significant increase in credit risk on that financial asset since initial recognition, an allowance is measured at an amount equal to 12-month expected credit losses. Otherwise, an allowance is measured at an amount equal to lifetime expected credit losses. The allowance for loan losses for individually significant impaired loans is calculated by the DCF method based on the present value of estimated future cash flows discounted at the financial asset’s original effective interest rate, which differs from the calculation of the DCF method under Japanese GAAP. The scope of loans that are subject to the DCF method under IFRS is wider than that under Japanese GAAP. ECL are measured in a way that reflects not only past events, but also current conditions and forecasts of future economic conditions.

(Loan origination fees and costs)

• Under Japanese GAAP, loan origination fees and costs are generally recognized in the consolidated income statement as incurred. Under IFRS, loan origination fees and costs that are incremental and directly attributable to the origination of a loan are deferred and thus, included in the calculation of the effective interest rate.

- 6 -

Defined benefit plans (Item 8)

(Calculation of discount rate and net interest)

• Under Japanese GAAP, the present value of the defined benefit obligation is measured using the market yields of long-term Japanese government bonds as discount rates. Under IFRS, the present value of the defined benefit obligation is measured using discount rates reflecting market yields on high-quality corporate bonds at the end of each reporting period.

• Under Japanese GAAP, the expected rates of return on plan assets are used to calculate the return on plan assets. Under IFRS, the interest cost and expected return on plan assets are replaced with a net interest amount which is calculated by applying the discount rate to the net defined benefit liability (asset).

(Treatment of actuarial gains and losses)

• Under Japanese GAAP, actuarial gains and losses are recognized in other comprehensive income and are amortized using the straight-line method. Under IFRS, actuarial gains and losses are recognized in other comprehensive income and are never reclassified to profit or loss.

(Asset ceiling)

• Under IFRS, when the net defined benefit asset is in surplus, the recognized asset is limited to the present value of any economic benefits available, whereas there is no such specific requirement under Japanese GAAP.

Deferred tax assets (Item 9)

• Under IFRS, deferred tax assets are recognized to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. For example, deferred tax assets for deductible temporary differences relating to impairment of financial instruments of which the timing of the reversal is difficult to estimate cannot be recognized under Japanese GAAP, whereas they can be recognized under IFRS to the extent that it is probable that future taxable profit will be available.

Classification of equity and liability (Item 11)

• Under IFRS, a financial instrument or its component parts are classified as equity instruments or financial liabilities in accordance with the substance of the contractual arrangement and the definitions of financial liabilities and equity instruments. A financial instrument is classified as a financial liability if there is a contractual obligation to deliver cash or another financial asset other than a fixed number of equity shares in exchange for a fixed amount of cash or another financial asset. In the absence of such a contractual obligation, the financial instrument is classified as an equity instrument.
