AIG's Underwriting Gains Highlighted Amid DeepValue's Sustainability Concerns

What happened

A recent Zacks article cites AIG's strong underwriting growth and $6.8 billion in shareholder returns, with analysts projecting 12.7% stock upside, framing it as a bullish signal. However, the DeepValue report cautions that recent performance, including Q3 2025's 86.8% combined ratio, heavily relies on transient factors like low catastrophe losses and favorable prior-year development. The report notes that AIG's valuation at $71.31 already prices in low-teens ROE and sub-mid-90s combined ratios, limiting upside if these benefits normalize as expected. Key risks include the CEO transition to Eric Andersen, increasing exposure to volatile alternative investments, and potential softening in pricing cycles. Thus, while the article promotes optimism, the underlying durability of AIG's underwriting profit remains unproven and warrants skepticism.

Implication

The highlighted underwriting gains are largely driven by favorable but non-recurring factors, such as benign catastrophe experience and reserve releases, which could reverse and pressure earnings. Shareholder returns, while substantial, have been funded by finite Corebridge stake sales, raising questions about future buyback capacity without organic cash flow. The ongoing CEO transition adds governance uncertainty, complicating AIG's strategic shifts into alternative assets and partnerships like CVC. Upcoming catalysts, including Q4 2025 results and further Corebridge monetization, will test whether underwriting discipline persists amid normalization. Until AIG demonstrates sustained sub-92% combined ratios with normalized cats, as per the DeepValue criteria, the risk-reward favors patience over immediate investment.

Thesis delta

The new article does not shift the core WAIT thesis from the DeepValue report, which remains skeptical due to earnings sustainability concerns and leadership transition risks. It reinforces the caution by highlighting growth that may be ephemeral, relying on one-off benefits rather than durable underwriting improvement. No upgrade is justified until 2026 results provide evidence of sub-92% combined ratios without excessive reliance on favorable development or low cats.
