Aon (AON) Stock Forecast & Price Target

Aon is positioned favorably because its brokerage-heavy model is supported by steady organic growth, persistent adjusted margin expansion, and disciplined expense management, which together underpin stronger earnings power over time. The USI purchase adds complementary middle-market scale, a clearer path to $400mm of synergies, and a leverage reset from 4.5x toward 3x within 24 months, while the NFP integration has already proved smoother than feared. With 2026E EPS of $19.10, 2027E EPS of $21.70, and 2028E EPS of $24.40, alongside more than $1 billion of FY26E share repurchases, the business appears set to convert free cash flow into accretive shareholder returns.

Aon is viewed negatively because the USI acquisition is priced at a demanding 22x EBITDA, far above Aon’s own 13x multiple, making the deal immediately dilutive and forcing leverage to take priority over share repurchases. The expected burden of roughly $877 million of interest expense in 2027, plus about $550 million of integration costs and $400 million of retention costs, creates meaningful earnings pressure before any synergy benefits can materialize. With organic growth tailwinds fading and weak economic conditions, slowing insurable risk demand, and sector-specific softness, the company’s historically stable capital management and earnings profile look less attractive.
