FY26 outlook (per Q4 2025 call, 2026-02-11)

FY26 frameworkDirection
General insurance NPW growthLow to mid-teens
Buyback intent≥$1B common shares
Corebridge proceedsLikely additional repurchases
Underwriting marginContinued discipline

The +low-to-mid-teens NPW growth is unusually strong for a mature P&C insurer — reflects pricing + new business + risk solution mix.

Key risks

  • Catastrophe losses: P&C exposure to wildfire + hurricane + severe weather.
  • Reinsurance market: Reinsurance pricing cycle affects net cession.
  • Underwriting cycle: Hard market currently favorable; soft market would compress margin.
  • Reserve adequacy: Long-tail commercial exposure; reserve adjustments material.
  • Investment portfolio: Interest rate cycle + credit cycle affect investment income.
  • Regulatory: P&C regulatory framework + state insurance commissioners.

Bottom line

AIG FY25 is the post-Corebridge focused-commercial-insurer year. Adj EPS +43% to $7.09; Q4 underwriting income +48%; combined ratio 88.9%. Buyback $-5.84B + FY26 ≥$1B intent + Corebridge proceeds. FY26 NPW guide low-to-mid-teens. Risks are catastrophe + reinsurance + reserve. Quality + capital + buyback.
