Material Changes vs. Prior Period
- Profitability Increase: Despite a 5.4% decrease in Ordinary Income (¥4.34 trillion vs. ¥4.59 trillion), Ordinary Profits increased by 13.7% to ¥849.6 billion. This was driven by a significant reduction in Ordinary Expenses, which fell to ¥3.49 trillion from ¥3.84 trillion.
- Expense Management: Interest Expenses decreased by ¥324 billion to ¥2.24 trillion. General and Administrative Expenses increased by ¥89 billion to ¥966 billion, primarily due to higher personnel expenses (¥467 billion vs. ¥420 billion).
- Asset Growth: Total Assets grew by approximately ¥5.4 trillion to ¥288.8 trillion. Notable increases were seen in Trading Assets (up ¥3.5 trillion) and Securities (up ¥4.1 trillion).
- Cash Flow: Net cash used in operating activities increased significantly to ¥2.25 trillion (from ¥1.22 trillion outflow), largely due to a net increase in deposits of ¥1.25 trillion and a decrease in trading assets of ¥3.36 trillion. Investing activities shifted from a net inflow of ¥253 billion to a net outflow of ¥3.1 trillion, driven by net purchases of securities.
- Loan Loss Provisions: The Allowance for Loan Losses decreased from ¥755.8 billion to ¥490.0 billion, reflecting a reversal of provisions which contributed to higher profits.

Investor Verification Checklist

- Share Repurchase Execution: Monitor the actual execution of the ¥200 billion share buyback program announced in November 2025.
- Trading Income Volatility: Review the decline in Trading Income (from ¥558 billion to ¥425 billion) and its impact on future earnings stability.
- Dividend Sustainability: Assess the ability to maintain the progressive dividend policy given the increase in personnel expenses and the upcoming capital outflow for share buybacks.
