Material Changes vs. Prior Period
- Profitability Surge: Net income attributable to shareholders increased by ¥252 billion (44.8%) to ¥816 billion. This was driven by a significant swing in investment gains (from a loss of ¥122 billion to a gain of ¥590 billion) and a 29.4% increase in net interest income.
- Net Interest Income: Increased by ¥174 billion due to a decline in interest expense on liabilities (down ¥339 billion) which more than offset a decrease in interest income from assets (down ¥165 billion). The average interest rate spread widened to 0.32%.
- Noninterest Income: Rose by ¥304 billion. While trading account gains decreased by ¥578 billion, this was overwhelmingly offset by a ¥711 billion improvement in investment gains (primarily equity securities) and a reduction in foreign exchange losses.
- Asset Quality: Nonaccrual loans decreased by 24.5% to ¥801 billion, with the ratio to total loans dropping to 0.8%. However, charge-offs increased significantly to ¥238 billion, primarily due to domestic corporate borrowers.
- Balance Sheet: Total assets grew by ¥5.1 trillion, led by increases in trading account assets (¥4.5 trillion) and investments (¥3.7 trillion).
Guidance, Outlook, and Management Commentary
- Shareholder Returns: Interim cash dividends were increased to ¥72.5 per share (up ¥7.5 from the prior year). The Board authorized a new share repurchase program of up to ¥200 billion (60 million shares) to be executed between November 2025 and February 2026. The company aims for a total payout ratio of 50% or more.
- Strategic Acquisitions:
- Completed acquisition of 76.9% of Upsider Holdings (AI technology) for approx. ¥46 billion.
- Completed acquisition of Augusta & Co Limited (renewable energy advisory) in Europe.
- Agreed to acquire >60% of Avendus Capital (India) for up to 47 billion INR, expected to close by July 2026.
- Capital Adequacy: The group maintained a strong capital position with a CET1 ratio of 13.70%, well above regulatory requirements. The group redeemed various Tier 1 and Tier 2 securities and issued new perpetual subordinated bonds to optimize capital structure.
- Risks: Management notes risks related to the pass-through of tariff costs, potential economic deterioration, and financial market disruption. The group continues to monitor the impact of interest rate fluctuations on trading account valuations.
Investor Verification Checklist
- Investment Gains Volatility: Verify the sustainability of the ¥590 billion investment gain, which was the primary driver of the profit surge, as it is largely driven by fair value changes in equity securities.
- Charge-off Trends: Monitor the significant increase in charge-offs (¥238 billion) despite the overall decline in nonaccrual loans, specifically regarding domestic corporate borrowers.
- Share Repurchase Execution: Track the execution of the newly authorized ¥200 billion share buyback program and its impact on earnings per share.
- Trading Account Exposure: Review the exposure to interest rate risk in trading accounts, which saw a decrease in gains due to rising long-term interest rates affecting receive-fixed, pay-variable swaps.
- Acquisition Integration: Assess the integration progress and expected synergies from the acquisitions of Upsider Holdings, Augusta & Co, and the pending Avendus Capital deal.
