Material Changes vs. Prior Period
- Record Profitability: Net income reached a record $10.31 billion, driven by double-digit growth in P&C underwriting income and Life segment income, alongside higher net investment income.
- Underwriting Performance: The P&C combined ratio improved to 85.7% (from 86.6% in 2024). This improvement was driven by lower catastrophe losses relative to prior years and favorable prior period development, despite higher catastrophe losses in 2025 primarily from California wildfires ($1.47 billion).
- Segment Growth:
- North America Commercial P&C: Underwriting income grew 17.6% to $3.78 billion.
- Life Insurance: Net premiums written increased 15.1% (17.3% in constant dollars), driven by growth in North Asia and Chubb Benefits.
- North America Personal P&C: Underwriting income declined 43.4% to $573 million due to significant catastrophe losses ($1.72 billion) from California wildfires, though the catastrophe-excluding combined ratio improved.
- Investment Income: Net investment income hit a record $6.47 billion, primarily due to higher average invested assets fueled by strong operating cash flows.
- Effective Tax Rate: The effective tax rate increased to 18.6% from 15.8% in 2024, largely due to the enactment of Bermuda's new 15% corporate income tax effective January 1, 2025.
Guidance, Outlook, and Risks
- Capital Management: The Board authorized a new $5.0 billion share repurchase program effective July 1, 2025. As of February 26, 2026, $2.11 billion remained available. Dividends for 2025 were $3.82 per share.
- Catastrophe Exposure: Modeled pre-tax probable maximum loss (PML) for a 1-in-100 year event is $5.86 billion (7.9% of shareholders' equity). The company notes that climate change may increase the frequency and severity of natural perils.
- Key Risks:
- Reserve Adequacy: Significant judgment is required for long-tail casualty reserves (e.g., workers' compensation, liability). A 1% change in tail factors for workers' comp could impact reserves by ~$1.1 billion.
- Reinsurance Counterparty Risk: $20.6 billion in reinsurance recoverables are held; insolvency of reinsurers could impact results.
- Regulatory & Tax: New tax regimes in Bermuda and the OECD global minimum tax framework are impacting the effective tax rate. Evolving regulations on AI, data privacy, and climate disclosure present compliance challenges.
- Run-off Liabilities: Corporate segment continues to face adverse development from legacy asbestos, environmental, and molestation claims.
Investor Verification Checklist
- Catastrophe Loss Development: Verify the finalization of 2025 California wildfire losses and their impact on the North America Personal P&C segment's combined ratio.
- Bermuda Tax Impact: Confirm the full-year impact of the new 15% Bermuda corporate income tax on the effective tax rate and future earnings projections.
- Reinsurance Recoverables: Review the valuation allowance for uncollectible reinsurance ($320 million) and the credit quality of the top reinsurers.
- Long-Tail Reserve Sensitivity: Assess the sensitivity of long-tail reserves (Workers' Comp, Liability) to changes in tail factors and inflation assumptions.
- Huatai Integration: Monitor the integration progress and financial performance of the Huatai Group (China) following full consolidation.
- Share Repurchase Execution: Track the execution of the new $5.0 billion share repurchase authorization and its impact on earnings per share.
