2. Reason for this decision

With the target of enhancing sustained growth in corporate value within the framework of an optimal capital structure, the Company's basic policy is to maintain stable returns of profits while retaining

internal reserves for investments in growth to expand earnings and enhance its corporate foundations. Under this basic policy, during the period covered by the Medium-Term Management Plan 2030, for which the final fiscal year is the year ending March 31, 2030, we plan to implement returns of profits targeting a consolidated payout ratio of approximately 70%.

For the fiscal year under review, the Company will increase its dividend by 20 yen per share to 115 yen per share from the most recently announced dividend forecast of 95 yen per share based on a

comprehensive consideration of various matters, including the above policy, the financial results announced in the Summary of Consolidated Financial Results for the Fiscal Year Ended March 31, 2026, which was released today, and forecasts of consolidated financial results for the next fiscal year.

Full-year dividends for the fiscal year ended March 31, 2026 will be 205 yen per share.
