Insights

Bank capital & equity actions analyst

SMFG launches up to JPY 150B buyback (1.3% of shares) with cancellation.

SMFG approved a repurchase of up to JPY 150,000,000,000 or 50,000,000 shares (1.3% of issued excluding treasury) from Nov 17, 2025 to Jan 31, 2026. All repurchased shares are scheduled for cancellation on Feb 20, 2026, which reduces share count once completed.

The mechanism uses market purchases under a discretionary dealing contract, meaning actual volumes depend on trading conditions and execution within the stated caps. The program targets shareholder returns and capital efficiency; its net effect hinges on how much of the JPY 150B cap is deployed.

Key anchors are the caps (shares and yen), the window through Jan 31, 2026, and the cancellation date. Baselines disclosed include 3,847,300,534 shares outstanding (ex‑treasury) and 10,107,106 treasury shares as of Oct 31, 2025.
