AIG Finalizes Corebridge Exit, Removing Key Capital Source

What happened

AIG has agreed to sell its remaining 25 million Corebridge shares for net proceeds of about $710 million, completing the multi-year separation from its life/retirement arm. This final cash infusion had been flagged by the DeepValue report as a finite source funding aggressive buybacks, which totaled over $5 billion in the first nine months of 2025. With the Corebridge stake fully monetized, AIG loses a key flexibility buffer, making future capital returns more reliant on organic earnings. The timing is critical as the company enters a CEO transition and increases exposure to alternative assets via CVC and other partnerships. The market likely prices in this conclusion, but the removal of the Corebridge tailwind reinforces the need for sustained underwriting performance under new leadership to maintain EPS growth.

Implication

Investors should monitor AIG's ability to maintain buyback pace from organic earnings, especially as the company increases allocations to less liquid alternatives. The conclusion of the Corebridge divestiture removes a significant source of capital flexibility, making future capital returns more dependent on underwriting margins staying in the high-80s accident-year range. If combined ratios revert to the mid-90s, buybacks will slow, pressuring EPS and valuation. The stock already trades at ~1x book, leaving limited upside unless the new CEO delivers sustained low-teens ROE without the Corebridge tailwind.

Thesis delta

The Corebridge sale closure removes a key pillar of the capital return thesis that helped support the stock price. While the sale was expected, its completion eliminates a source of future buyback funding, making organic earnings the sole driver of capital returns. This increases execution risk, particularly given the CEO transition and expanding alternative asset exposure.
