2. Details of the Stock Split

   1. Method

      With Wednesday, September 30, 2026 set as the record date, each share of the Company’s common stock held by shareholders recorded in the shareholder register as of that date will be split into two (2) shares.

      Any fractional shares resulting from the stock split will be aggregated and sold or purchased, and the proceeds will be distributed to shareholders in proportion to their respective fractional entitlements.

3. Other Matters

   1. Changes in Authorized Shares and Capital

      There will be no changes to the Company’s total number of authorized shares or its capital stock as a result of the stock split.

   2. Dividends

As the stock split will become effective on October 1, 2026, the year-end dividend for the fiscal year ending March 31, 2027 will be paid based on the number of shares after the stock split.

• The forecast year-end dividend per share for the fiscal year ending March 31, 2027 reflects the impact of this stock split, and therefore the total annual dividend per share is shown as “–”. If the stock split is not taken into account, the forecast year-end dividend per share for the fiscal year ending March 31, 2027 would be ¥60, and the total annual dividend would be ¥120.

• The dividend payout ratio and DOE for the fiscal year ending March 31, 2027 have been calculated on an estimated basis, using the number of issued shares, the number of treasury shares, and shareholders’ equity per share as of the fiscal year ended March 31, 2026.

• For details of the full-year dividend forecast, please refer to the “Suzuken Announces Shareholder Return Policy and Full-Year Dividend Forecast for the Fiscal Year Ending March 31, 2027 (Dividend Increase)” disclosed separately today.
