American International Group (AIG) continues to attract attention as investors weigh its recent share performance against underlying fundamentals, including revenue of US$26.8b, net income of US$3.1b, and mixed returns across the past year and the past 3 months.

The recent 1 day share price return of 4.6% and 1 month share price return of 5.9% suggest improving momentum, while the 5 year total shareholder return of 103.2% highlights how longer term holders have been rewarded.

With AIG trading at US$78.44 and an estimated intrinsic discount of about 52%, plus a discount to the current analyst price target, the key question is whether this reflects a genuine mispricing or whether the market has already incorporated expectations about future growth.

Most Popular Narrative: 9.8% Undervalued

With American International Group's fair value narrative sitting at $86.95 against a last close of $78.44, the gap between model and market is clear and invites a closer look at what is driving that number.

The acceleration of digitalization and artificial intelligence initiatives, such as the Gen AI deployment across underwriting and claims, positions AIG to enhance operational efficiency, improve underwriting precision, reduce fraud, and offer more tailored insurance products, supporting improved net margins and sustained earnings growth.

Result: Fair Value of $86.95 (UNDERVALUED)

However, investors still need to watch for softer commercial and reinsurance pricing, as well as higher catastrophe and liability losses, which could squeeze margins and challenge that undervalued case.

Another Angle On AIG’s Valuation

The earnings based fair value of $86.95 suggests AIG looks 9.8% undervalued, but the P/E story is less generous. At 13.6x, the shares sit above both the US Insurance industry at 12.6x and peers at 10.9x, while the fair ratio is 14.6x. This raises the question of whether this is a sensible premium or an indication of additional valuation risk.
