   2. Reason

      The Company positions the return of profits to shareholders as one of its priority management policies. In principle, the Company strives to return profits commensurate with its financial results on an ongoing basis while securing the internal reserves necessary to ensure stable future growth and to respond to changes in the business environment.

      In comprehensive consideration of the policy mentioned above and the trends of its financial results, the Company

      will pay a dividend per share of 80 yen (an increase of 20 yen from the previous fiscal year) as the year-end dividend for FY2024. The annual dividend per share for the same fiscal year will be 130 yen, an increase of 30 yen from that of the previous fiscal year of 100 yen (the sum of an interim dividend of 40 yen and a year-end dividend of 60 yen).

2. Dividend forecast for the fiscal year ending March 2026

As for the Company's dividend forecast for FY2025, in comprehensive consideration of the dividend policy and the trends of its financial results, the Company plans to pay a dividend per share of 230 yen (an increase of 100 yen from the result for FY2024).

Going forward, based on an annual dividend of 230 yen, the Company will pay "progressive dividends," which means the Company will either maintain or increase the amount of annual dividend per share every year.
