UNAUDITED QUARTERLY CONSOLIDATED JAPANESE GAAP FINANCIAL STATEMENTS

AS OF AND FOR THE THREE MONTHS ENDED JUNE 30, 2023

On August 14, 2023, we published our unaudited quarterly consolidated financial statements as of and for the three months ended June 30, 2023 prepared in accordance with accounting principles generally accepted in Japan, or Japanese GAAP, as part of our quarterly securities report (shihanki hokokusho) for the same period filed by us with the relevant Japanese authorities. This document is an English translation of the unaudited quarterly consolidated financial statements and the notes thereto included in such quarterly securities report. Japanese GAAP differs in certain respects from International Financial Reporting Standards as issued by the International Accounting Standards Board, or IFRS, and generally accepted accounting principles in the United States. For a description of certain differences between IFRS and Japanese GAAP, see “Item 5.A Operating Results—Reconciliation with Japanese GAAP” in our most recent annual report on Form 20-F filed with the SEC.

NOTES TO UNAUDITED QUARTERLY CONSOLIDATED FINANCIAL STATEMENTS

(Basis of presentation)

Sumitomo Mitsui Financial Group, Inc. (“the Company”) was established on December 2, 2002 as a holding company for the SMBC Group (“the Group”) through a statutory share transfer (kabushiki iten) of all of the outstanding equity securities of Sumitomo Mitsui Banking Corporation (“SMBC”) in exchange for the Company’s newly issued securities. The Company is a joint stock corporation with limited liability (Kabushiki Kaisha) incorporated under the Companies Act of Japan. Upon formation of the Company and completion of the statutory share transfer, SMBC became a direct wholly owned subsidiary of the Company.

The Company has prepared the accompanying consolidated financial statements in accordance with the provisions set forth in the Japanese Financial Instruments and Exchange Act and its related accounting regulations, and in conformity with accounting principles generally accepted in Japan (“Japanese GAAP”), which are different in certain respects as to application and disclosure requirements from International Financial Reporting Standards (“IFRS”).

The accounts of overseas subsidiaries and affiliated companies are, in principle, integrated with those of the Company’s accounting policies for purposes of consolidation unless they apply different accounting principles and standards as required under U.S. GAAP or IFRS, in which case a certain limited number of items are adjusted based on their materiality.

These consolidated financial statements are translated from the consolidated financial statements contained in the quarterly securities report filed under the Financial Instruments and Exchange Act of Japan (“FIEA based financial statements”) except for the addition of U.S. dollar figures.

Amounts less than ¥1 million have been rounded down. As a result, the totals in Japanese yen shown in the financial statements do not necessarily agree with the sum of the individual amounts.

The translation of the Japanese yen amounts into U.S. dollars is included solely for the convenience of readers outside Japan, using the prevailing exchange rate at June 30, 2023 which was ¥144.99 to US$1. These translations should not be construed as representations that the Japanese yen amounts have been, could have been, or could in the future be, converted into U.S. dollars at that rate.

Accounting treatment of tax expenses

Amounts of Income taxes include Income taxes-deferred.

Bonds classified as held-to-maturity and other securities (excluding other securities whose quarterly consolidated balance sheet amounts are not measured at fair value) are considered as impaired if the fair value decreases materially below the acquisition cost and such decline is not considered as recoverable. The fair value is recognized as the quarterly consolidated balance sheet amount (consolidated balance sheet amount) and the amount of write-down is accounted for as valuation loss for the period. Valuation losses for the fiscal year ended March 31, 2023 and for the three months ended June 30, 2023 were ¥408 million and ¥2,281 million, respectively. The rule for determining “material decline” is as follows and is based on the classification of issuers under the rules of self-assessment of assets.

Bankrupt issuers: Issuers that are legally bankrupt or formally declared bankrupt.

Effectively bankrupt issuers: Issuers that are not legally bankrupt but regarded as substantially bankrupt.

Potentially bankrupt issuers: Issuers that are not bankrupt now, but are perceived to have a high risk of falling into bankruptcy.

Issuers requiring caution: Issuers that are identified for close monitoring.

Normal issuers: Issuers other than the above 4 categories of issuers.
