AIG - American International Group Inc
Executive Summary
American International Group Inc is a global insurance group serving commercial, institutional and individual customers through its General Insurance and Legacy Life and Retirement businesses; its common stock is listed on the New York Stock Exchange under the ticker AIG, and it is positioned as a major diversified insurer.
The investment case depends on continued underwriting discipline, delivery of the transformation benefits from the completed Corebridge Financial exit, and improved profitability, with the next scheduled earnings release on 7 November 2026 providing the principal near-term catalyst; the primary risk is that catastrophe losses, adverse reserve development or regulatory compliance failures offset earnings growth and delay further capital returns.
BUY. Conviction Score: 67/100. The view would change if deteriorating underwriting performance, material adverse reserve development or sustained regulatory constraints undermine cash generation and capital returns.
Thesis break: The thesis would be invalidated by a sustained General Insurance combined ratio above 90.0%, material adverse reserve development, regulatory restrictions that prevent capital returns, or a further strategic action that increases capital intensity without credible earnings benefits.
Business Model
AIG generates revenue primarily from insurance premiums, including General Insurance net premiums written of USD7.5 billion in the second quarter of 2026, up 9% year on year on both reported and constant-dollar bases. It earns investment income on insurance float and also receives fees, commissions and other income from its Legacy Life and Retirement operations. General Insurance underwriting income was USD686 million in the second quarter of 2026, up 10% year on year.
General Insurance serves commercial, institutional and individual customers through commercial and specialty lines, accident and health, personal lines and other insurance products. In the second quarter of 2026, growth was reported across all three General Insurance business segments. The group also sells life, retirement, accident and health products, although the Corebridge Financial stake sale completed in May 2026 reduced AIG's former ownership exposure to the life insurance and retirement division.
AIG's competitive advantage rests principally on underwriting expertise, scale, product breadth, distribution capabilities and the ability to spread catastrophe risk across a diversified portfolio; these characteristics are not a guarantee of excess returns because insurance pricing is cyclical and claims can exceed premiums unexpectedly. General Insurance reported an 89.0% combined ratio and an 88.1% accident-year combined ratio, as adjusted, in the second quarter of 2026, both improving by 30 basis points year on year. A 10% increase in underwriting income alongside positive combined ratios indicates that underwriting execution was a material source of first-half strength.

Thesis Evaluation
Bull Case (36% weight)
General Insurance sustains broad-based premium growth near the 9% year-on-year rate recorded in the second quarter of 2026 while the combined ratio remains around 89.0% and catastrophe losses remain manageable. Continued margin improvement, effective capital deployment and a lower risk profile after the Corebridge disposal could support a rerating to $94 over the next 12 months.
Base Case (48% weight)
Premium growth moderates from the second-quarter rate, while underwriting remains profitable and the combined ratio stays near 90.0%. Continued progress on portfolio simplification and steady earnings support a 12-month target of $84, implying moderate appreciation from the current price of USD79.58.
Bear Case (16% weight)
Catastrophe losses, adverse reserve development or tighter regulatory capital requirements cause earnings and capital generation to fall materially below the base case. Multiple compression in the diversified insurance valuation then drives the share price to $66 over the next 12 months.
Key Risks
- Catastrophe and underwriting volatility: Severe catastrophe events, reserve deterioration or inadequate pricing could push the combined ratio above 90.0% and weaken earnings and capital generation. Estimated probability: 35%. Impact: severe.
- Regulatory and capital requirements: AIG's regulated subsidiaries face evolving capital, liquidity, conduct and distribution requirements across jurisdictions, which could constrain profitability, dividends or buybacks. Estimated probability: 30%. Impact: moderate.
- Integration and portfolio execution: Failure to realise benefits from the completed Corebridge disposal or from continuing portfolio simplification could leave AIG exposed to businesses that contribute less attractive or less predictable returns. Estimated probability: 25%. Impact: moderate.
- Investment portfolio and interest-rate sensitivity: Changes in credit spreads, defaults or interest rates could reduce investment income and the value of securities held to support insurance liabilities. Estimated probability: 25%. Impact: moderate.
- Leadership transition: Recent leadership changes could slow strategic decisions or weaken accountability if the new structure does not execute effectively. Estimated probability: 20%. Impact: low.
Who Should Own It / Avoid It
Ideal for: A diversified investor with a minimum 12-month holding period who accepts catastrophe volatility, regulatory exposure and moderate cyclicality in exchange for a global insurance franchise, improving underwriting performance and potential capital returns; the investor should tolerate material drawdowns if underwriting or reserve performance deteriorates.
Avoid if: An investor cannot tolerate claims volatility, regulatory intervention or fluctuations in insurance-sector valuations, or who needs predictable dividends and low earnings volatility; AIG is unsuitable for capital-preservation mandates and short-horizon investors because the next scheduled earnings release on 7 November 2026 may materially affect expectations.
Recommendation
BUY - 67/100. AIG's diversified insurance franchise, second-quarter underwriting momentum, 9% net premiums written growth and completed Corebridge disposal support the recommendation, while the current price of USD79.58 leaves moderate upside to the base-case target. The call would be upgraded if underwriting profitability remains near the second-quarter 2026 combined ratio of 89.0%, catastrophe losses remain controlled and capital returns become clearer. It would be degraded by a sustained combined ratio above 90.0%, material adverse reserve development, regulatory capital constraints or weaker-than-expected results on 7 November 2026. At the current price of $82.57 the shares trade above our buy ceiling of $72.00: the thesis is credible but the price is not - new positions only below that level.
The probability-weighted value across our three scenarios is $84.72, 3% above the current price of $82.57 - the market has not yet priced our probability-weighted view. Levels below are derived from the scenario targets and probabilities above, not from percentage offsets to today's price.
below $72.00 - below this level the upside to the base-case target ($84.00) is at least 2x the downside to the bear case ($66.00), the minimum risk/reward we require before committing new capital.
between $72.00 and $84.00 - the base case is not yet fully priced, so existing holders are paid to wait, but new money gets no margin of safety in this zone.
above $84.00 - at this level the base case is fully reflected in the price and anything beyond it is paying for a bull scenario we weight at 36%.
if the thesis would be invalidated by a sustained General Insurance combined ratio above 90.0%, material adverse reserve development, regulatory restrictions that prevent capital returns, or a further strategic action that increases capital intensity without credible earnings benefits, regardless of price - the bear target of $66.00 is the backstop, not an arbitrary percentage stop.
