AIG Names New Global CUO; Underwriting Focus Continues

What happened

Nancy Bewlay joins AIG as EVP, Global Chief Underwriting Officer, effective September 8, 2026, reporting to CEO Eric Andersen. The hire fills a critical role as AIG navigates leadership transition and seeks to sustain the improved underwriting margins achieved under former CEO Zaffino. Bewlay's appointment signals continuity in AIG's emphasis on underwriting discipline, even as the company expands into alternative investments and specialty lines. However, the DeepValue report highlights that AIG's recent underwriting profitability relied heavily on favorable catastrophe experience and prior-year development, which may normalize. The market should watch whether Bewlay can maintain accident-year combined ratios in the high-80s amid a softening pricing cycle and growing exposure to volatile asset classes.

Implication

Investors should view the hire as a modest positive signal that AIG's board is prioritizing underwriting expertise during the CEO transition. However, the DeepValue report maintains a WAIT stance, noting that AIG's current valuation (~1.0x book, ~12.6x P/E) offers limited upside given the dependency on transient factors. The new CUO will need to prove that high-80s accident-year combined ratios are sustainable beyond the current benign cat environment and without heavy reliance on favorable prior-year development. Until there is clear evidence that underwriting margins can hold in a more normalized cycle, the risk/reward remains balanced. A more attractive entry would be around $65, with a re-assessment window of 6-12 months to evaluate 2026 results under the new leadership team.

Thesis delta

The appointment of Nancy Bewlay as Global CUO slightly strengthens our thesis that AIG can maintain underwriting discipline post-transition, but does not alter our WAIT rating. The fundamental uncertainty around catastrophe normalization, reserve development, and the impact of new alternative investments remains unchanged. We continue to require evidence from 2026 results that high-80s accident-year combined ratios are achievable without the tailwinds seen in 2024-2025.
