I. Schedule Merger resolution - Board resolution date: 2026-03-31 Merger agreement date: 2026-04-07 Record date for determining shareholders: 2026-04-17 Period for receiving notices of objection to the merger - Start date: 2026-04-20; End date: 2026-05-04 Merger approval - Board resolution date: 2026-05-06 Creditor objection filing period - Start date: 2026-05-11; End date: 2026-06-11 Merger effective date: 2026-09-01 Completion report - Board resolution date and announcement: 2026-09-01 Scheduled date of merger registration: 2026-09-09 Note 1) Since this merger is a small-scale merger, the shareholders' meeting for merger approval is replaced by a board resolution, and dissenting shareholders are not granted appraisal (share purchase demand) rights. Note 2) The above record date for determining shareholders is the record date for expressing opposition to the small-scale merger. Note 3) For Agos Co., Ltd., the surviving company, the shareholders' meeting to report completion of the merger is replaced, by board resolution, with a notice posted on the website as provided in the articles of incorporation. Note 4) The above scheduled date of merger (dissolution) registration is based on the date the registration application is filed.

II. Changes in the holdings of the largest shareholder, etc. Agos Co., Ltd. owns 100% of the shares of Human Agos Co., Ltd., and because the merger ratio is 1:0 (a merger without capital increase through absorption), no new shares are issued and there is no change in the largest shareholder's holdings.

III. Exercise of appraisal (share purchase demand) rights Agos Co., Ltd., the surviving company, qualifies as a small-scale merger under Article 527-3 of the Commercial Act, so no appraisal rights are granted. Human Agos Co., Ltd., the dissolving company, is a wholly owned (100%) subsidiary of Agos Co., Ltd., so no appraisal rights arise.

IV. Matters concerning creditor protection Agos Co., Ltd., the surviving company, and Human Agos Co., Ltd., the dissolving company, each published a public notice and demand for creditors to raise objections on May 11, 2026, and no creditor raised any objection by the close of the objection period on June 11, 2026.

V. Status of related litigation As of the merger effective date, no lawsuit has been filed that could affect the validity of the merger.

VI. Matters concerning the allotment of new shares, etc. Because this merger does not involve the issuance of new merger shares to the wholly owned subsidiary (merger ratio 1:0), no new shares are issued, and no separate merger cash payment has been made.
