2. Notice Concerning the Convening of an Adjourned Session of the 26th Annual General Meeting of Shareholders

Of the agenda for the 26th Annual General Meeting of Shareholders (hereinafter referred to as the "Meeting"), we plan to report "The Business Report, the Consolidated Financial Statements for the 26th term (For the year ended March 31, 2026), and reports of the audit results on the Consolidated Financial Statements by the Accounting Auditors and the Board of Corporate Auditors" and "The Non-Consolidated Financial Statements for the 26th term (For the year ended March 31, 2026)" (hereinafter referred to collectively as the "Reporting Matters") to shareholders at the Meeting.

However, as we announced in "Notice Concerning the Publication of the Investigation Report by the Special Investigating Committee" dated April 3, 2026, and other notices, inappropriate accounting practices were discovered at us and several subsidiaries within the Group. As a result, the financial closing procedures and the audit procedures conducted by the Accounting Auditors for the fiscal year ended March 31, 2026, have not yet been completed. Consequently, we are unable to present the Reporting Matters at this General Meeting of Shareholders.

Accordingly, we plan to hold a separate session of the Meeting (hereinafter referred to as the "Adjourned Session") to present the Reporting Matters. We also intend to seek the approval of shareholders on the day of the Meeting for a proposal (hereinafter referred to as the "Proposal") to leave decisions regarding the date, time, and venue of the Adjourned Session to the discretion of the Board of Directors.

Once the Proposal has been approved at the Meeting, we intend to send separate notice to all shareholders regarding the arrangements for the Adjourned Session before convening the Adjourned Session.

The Adjourned Session is part of the Meeting; therefore, the shareholders eligible to attend the Adjourned Session are the same as those eligible to exercise their voting rights at the Meeting.

We deeply and sincerely apologize for the great inconvenience and concern caused to our shareholders.
