MCG's basic policy for shareholder returns is to enhance its shareholder value by increasing corporate value.

While keeping an eye to increasing retained earnings that will fund its future business activities, MCG will aim to maintain a target dividend payout ratio of 35% under the "Medium-Term Management Plan 2029," with a potential dividend increase based on further profit growth.

After comprehensively considering the policy above as well as business development going forward, the year-end dividend per share for the fiscal year ended March 31, 2026, will be ¥16.
