Material Changes and Drivers
- Investment Performance: The decline in GAAP net earnings was primarily driven by a shift from net investment gains of $1.3 billion in 2024 to net investment losses of $572 million in 2025. This included $467 million in losses from derivatives and foreign currency activities, and a $191 million increase in credit loss allowances.
- Foreign Exchange: The average yen/dollar exchange rate was 149.32 in 2025, 1.1% stronger than 2024. The stronger yen positively impacted adjusted earnings per share by $0.04.
- Segment Performance:
- Aflac Japan: Pretax adjusted earnings decreased 1.5% to $3.44 billion. Net earned premiums declined 2.7% due to internal reinsurance transactions and limited-pay products reaching paid-up status. However, new annualized premium sales increased 18.1% (in dollars) driven by new product launches (Miraito, Tsumitasu).
- Aflac U.S.: Pretax adjusted earnings were essentially flat at $1.42 billion. Net earned premiums increased 2.9% due to improved sales, though benefit ratios increased due to higher incurred claims.
- Cyber Incident: In June 2025, the Company experienced an unauthorized access incident involving the exfiltration of personal information for approximately 22.65 million individuals. The Company does not believe this will have a material financial impact, though it incurred costs for remediation and credit monitoring.
Guidance, Outlook, and Risks
- 2026 Outlook: The Company expects to maintain solid pretax profit margins.
- Aflac Japan: Target benefit ratio of 60-63% and expense ratio of 20-23%.
- Aflac U.S.: Target benefit ratio of 48-52% and expense ratio of 36-39%.
- Capital Deployment: In November 2025, the Board announced a 5.2% increase in the quarterly cash dividend. The Company repurchased $3.5 billion (33.0 million shares) of common stock in 2025, with 114.3 million shares remaining authorized for repurchase.
- Key Risks:
- Interest Rate Risk: Significant exposure to interest rate fluctuations affecting the fair value of fixed maturity securities and policy liabilities.
- Foreign Currency: Continued volatility in the yen/dollar exchange rate impacts reported results and regulatory capital.
- Credit Risk: Exposure to commercial real estate and highly leveraged companies in the investment portfolio.
- Regulatory: Changes in tax laws (Japan tax rate increasing to 28.9% in 2026) and insurance regulations.
Investor Verification Checklist
- Investment Portfolio Quality: Verify the extent of unrealized losses in the fixed maturity portfolio, particularly regarding commercial real estate and Japanese Government Bonds (JGBs), and the adequacy of credit loss allowances.
- Cyber Incident Costs: Monitor future filings for updates on litigation, regulatory fines, and remediation costs stemming from the June 2025 data breach.
- Japan Solvency Ratios: Confirm Aflac Japan's Solvency Margin Ratio (SMR) and Economic Solvency Ratio (ESR) remain well above regulatory minimums despite market volatility.
- Dividend Capacity: Assess the ability of Aflac Japan to continue remitting dividends to the Parent Company given the impact of unrealized losses on regulatory capital calculations.
- Benefit Ratios: Track the trend in Aflac U.S. benefit ratios to ensure they remain within the guided range of 48-52% as new products are introduced.
