Material Changes vs. Prior Period
- Profitability Surge: Net income swung from a loss of $1.4 billion in 2024 to a profit of $3.1 billion in 2025. This was primarily driven by the absence of a $3.6 billion loss from discontinued operations (Corebridge deconsolidation) in 2024, lower catastrophe losses ($258 million reduction), and favorable prior year reserve development ($183 million).
- Underwriting Performance: The General Insurance business achieved a combined ratio of 90.1, improving by 1.7 points. This was driven by a lower loss ratio (down 0.8 points) and a lower expense ratio (down 0.9 points).
- Investment Results: Net investment income decreased slightly by 1% to $4.2 billion due to lower gains on fair value changes and Corebridge dividends, partially offset by higher income from fixed maturity securities. Net realized losses increased to $1.2 billion, driven by impairments on real estate funds and derivative losses.
- Segment Performance:
- North America Commercial: Underwriting income increased 109% to $1.1 billion, driven by lower catastrophe losses and favorable reserve development.
- International Commercial: Underwriting income decreased 9% to $1.1 billion due to a higher accident year loss ratio.
- Global Personal: Underwriting income decreased 51% to $70 million, impacted by the sale of the global individual personal travel insurance business and higher catastrophe losses.
Guidance, Outlook, and Risks
Management Commentary & Strategic Actions:
- Capital Return: AIG returned approximately $6.8 billion to shareholders in 2025, including $5.8 billion in stock repurchases (reducing shares by 11%) and $1.0 billion in dividends. A new $7.5 billion share repurchase authorization was approved in April 2025.
- Strategic Investments: Announced investments in Convex Group ($2.1 billion) and Onex Corporation ($646 million). Acquired renewal rights of Everest Group's global retail commercial portfolios for $301 million.
- Rating Upgrades: Received upgrades to financial strength ratings from S&P, Moody's, and Fitch in 2025, with A.M. Best affirming its rating with a positive outlook.
Risks and Contingencies:
- Reserve Uncertainty: Significant judgment is required in estimating loss reserves, particularly for long-tail lines like U.S. Excess Casualty and Workers' Compensation. Adverse development could materially impact results.
- Catastrophe Exposure: The company remains exposed to natural and man-made catastrophes. Modeled 1-in-250 year probable maximum loss (PML) is $2.5 billion (net of reinsurance).
- Investment Concentration: The portfolio has significant exposure to commercial real estate and financial institutions. Credit spreads and interest rate fluctuations impact asset valuations.
- Regulatory Environment: AIG is subject to extensive regulation globally, including evolving standards on capital (IAIS Insurance Capital Standard), cybersecurity, and climate change disclosures.
Key Facts for Investor Verification
- Corebridge Deconsolidation Impact: Verify the sustainability of earnings growth by analyzing results excluding the one-time $3.6 billion loss from discontinued operations recorded in 2024.
- Reserve Development: Monitor the $548 million of favorable prior year loss reserve development in 2025 to ensure it is not an anomaly, particularly in U.S. Workers' Compensation and Property lines.
- Share Repurchase Authorization: Confirm the remaining balance of the $7.5 billion repurchase program (approx. $3.9 billion remaining as of Dec 31, 2025) and future execution plans.
- Investment Impairments: Review the $403 million "Other" net realized loss in 2025, primarily driven by impairments on real estate funds, for potential future exposure.
- Reinsurance Recoverability: Assess the $28.9 billion in reinsurance recoverables and the adequacy of the $248 million allowance for credit losses and disputes.
