The Company's basic policy is to maintain a continuous dividend payout ratio of approximately 40% while considering R&D and capital investment for long-term growth and new business development.

Furthermore, with an emphasis on continuing stable profit distribution to shareholders, the Company sets the minimum annual dividend per share of 20 yen.

In addition, in order to further enhance shareholder returns, the Company aims for a total return ratio of approximately 60% through flexible treasury share acquisitions.

Based on this policy, the Company proposes the year-end dividend for the current fiscal year of

26.25 yen per share. The dividend payout ratio (consolidated) will be 49.8%.

1. Type of dividend:

   Cash

2. Allotment of dividend property and its total amount:

   26.25 yen per share of common stock of the Company Total amount: 4,279,342,016 yen

   (Note) The Company conducted a 4-for-1 stock split of its common stock effective July 1, 2025. The interim dividend paid with a record date of June 30, 2025 (40 yen per share) is equivalent to 10 yen per share after the stock split. Accordingly, the total annual dividend equivalent for the current fiscal year, including the year-end dividend, amounts to 36.25 yen per share. This represents an effective increase in the annual dividend of 1.25 yen per share.

3. Effective date of the dividend from surplus: March 30, 2026
