8)	Content of the Agreement between the Person Solicited and the Reporting Company

[Content of the Plan]

Under the Plan, SMFG and SMFG’s subsidiaries will award restricted stock to eligible executives. The Plan consists of Stock Compensation I (medium-term performance incentives), Stock Compensation II (non-performance-based compensation for Outside Directors of SMFG and Sumitomo Mitsui Banking Corporation, SMFG’s full-time Audit Committee Members, and Sumitomo Mitsui Banking Corporation’s full-time Audit and Supervisory Committee Members), and Stock Compensation III (promotion reward). Although Stock Compensation (Bonus), determined based on annual performance, etc., is not provided for under the Plan as revised following certain amendments in FY2026, this Issuance of Shares includes Stock Compensation (Bonus) under the Plan prior to such amendments. SMFG will enter into Allotment Agreements for each category of stock compensation. The Allotment Agreements and the Regulations on Stock Compensation Plans stipulate i) the period during which disposals of the allotted shares are restricted in any manner, including the transfer of ownership or granting of security interest (the “Period”), ii) the conditions for releasing transfer restrictions as determined by the SMFG Compensation Committee, such as performance conditions (the “Release Conditions”), and iii) the conditions for SMFG acquiring all or part of the allotted shares at nil cost (the “Acquisition Conditions”), etc. Thus, SMFG’s common stock subject to this extraordinary report falls under the category of specified restricted transferable stock as stipulated in Article 54, Paragraph 1 of the Corporation Tax Act and Article 84, Paragraph 1 of the Order for Enforcement of the Income Tax Act.

The Issuance of Shares will be made through a contribution in kind of monetary compensation claims totaling ¥ 10,977,795,216 to be provided by SMFG or its wholly owned subsidiaries to the eligible executives as the allocation for the amount to be paid in for the restricted stock under the Plan.

	l	Notwithstanding the above, if the Executive leaves the position due to expiration of term or any other legitimate reason, the restriction shall be released for all shares allotted based on such position on the first business day of the month following the month in which the final day of the Period falls.

	l	However, in the event of the Executive’s death, the restriction shall be released on the date determined by SMFG upon consultation with the heir(s) or their representative without waiting for expiry of the Period.

9)	Methods for Segregating the Allotted Shares from Shares Not Subject to Restrictions on Transfer

In order to ensure that the allotted shares may not be transferred, pledged, collateralized, gifted before death, bequeathed or otherwise disposed of during the Period, the allotted shares shall be managed during the Period in dedicated accounts opened with SMBC Nikko Securities Inc. by the eligible executives, separately from other shares not subject to restrictions on transfer, and even if an eligible executive makes a request, any transfer of the allotted shares managed in such dedicated account will be restricted. In order to ensure the effectiveness of the restrictions on transfer of the allotted shares, SMFG and SMBC Nikko Securities Inc. have entered into an agreement for the management of the accounts for the allotted shares held by the eligible executives. In addition, the eligible executives are deemed to have agreed to the details of the management of such dedicated accounts.
