Analysis · MFG · Finance
Mizuho's board expanded its existing share repurchase program by ¥100 billion, doubling the total authorization to ¥200 billion. The maximum share count rose from 25 million to 35 million shares, now representing 1.4% of outstanding stock. The repurchase window was extended by one month to September 30, 2026, with cancellation now set for October 23. This follows strong Q1 FY2026 results reported today, where profit jumped 45.5% to ¥422.9 billion and full-year guidance was raised. The buyback expansion signals confidence in capital adequacy and a commitment to the 50%+ total payout ratio policy, but the incremental size is modest relative to Mizuho's ¥12.1 trillion market cap.
