2. Reason for the Dividend Increase

Recognizing returns of profits to shareholders to be a key management topic, the Company has established the basic policy of paying appropriate dividends that reflect financial results while continuing to strengthen and enhance its corporate foundations. During the period from FY2023 through the end of Phase 2 (FY2023-FY2027) of the SHIFT2030 medium- to long-term business plan, the Company will follow the basic policy and meet shareholder expectations through continued stable, steady increases in dividends (of at least 10 yen/share per year) targeting a consolidated payout ratio of at least 30% and a dividends-on-equity (DOE) ratio of at least 2.5%.

Based on this policy, and after comprehensively considering the financial results for the fiscal year ended March 31, 2026 announced on May 8, 2026, as well as the Company's current financial condition and future business developments, the year-end dividend per share for the fiscal year ended March 31, 2026 is scheduled to be 88 yen, an increase of 15 yen from the previous forecast of 73 yen per share. As a result, a full-year dividend will be 160 yen per share, including the interim dividend of 72 yen per share, an increase of 25 yen compared to the previous

fiscal year's ordinary dividend of 135 yen, excluding the commemorative dividend of 5 yen.

The above will be implemented subject to the resolution at the 97th Ordinary General Meeting of Shareholders scheduled on June 25, 2026.
