Aon (AON): Assessing Valuation After New AI Efficiency Push and Workforce Shift to Lower-Cost Regions

Listen to the news

Aon (AON) is back in focus after fresh commentary around its AI initiatives and workforce shift to lower cost regions, moves that could quietly reshape margins and long term earnings power.

See our latest analysis for Aon.

Despite the buzz around AI and leadership changes, Aon’s 1 year total shareholder return is down, and the 90 day share price return of negative 6.71 percent suggests momentum has softened, even as its 3 year total shareholder return of 15.68 percent and 5 year total shareholder return of 75.94 percent still point to a resilient long term compounding story.

If Aon’s efficiency push has you rethinking where durable growth could come from next, it might be worth exploring Is Aon financially strong enough to weather the next crisis? as well as fast growing stocks with high insider ownership for fresh ideas.

With Aon’s shares lagging over the past year despite solid earnings growth, AI driven margin ambitions, and a double digit discount to analyst targets, investors may be wondering whether this weakness represents a buying opportunity or whether the market is already pricing in future upside.

Most Popular Narrative: 13.8% Undervalued

With Aon last closing at $345.20 against a most popular fair value view of roughly $400.50, the narrative is leaning toward meaningful upside if its long term plan delivers.

Aon's 3x3 Plan and the deployment of Risk Analyzers have increased new business and improved client retention, strengthening the foundation for ongoing revenue growth and margin expansion.

Want to see what powers that confidence? The narrative leans on steadily rising revenues, fatter margins, and a punchy earnings multiple that rivals high conviction compounders. Curious which forecasts really move the needle on that fair value calculation? Read on to unpack the full story behind the numbers.

Result: Fair Value of $400.50 (UNDERVALUED)

However, sustained macro volatility and a softer commercial risk pricing cycle could easily cap revenue growth and challenge the premium multiple that this narrative assumes.

Another Way to Look at Value

On earnings, the picture looks very different. Aon trades on about 27.3 times earnings, more than double the US Insurance industry at 12.8 times, peers at 25.4 times, and well above a fair ratio of 15.7 times. This points to meaningful valuation risk if sentiment cools.
