Valuation of AON

Where Do Estimates for AON Stand?
Aon is expected to deliver year-over-year earnings growth of 11.7% in 2026 to $19.07 per share, followed by an additional 11.1% increase in 2027. Over the past month, analysts have raised 2026 earnings estimates eight times versus three downward revisions. The consensus estimate for 2026 revenues is pegged at $17.99 billion, implying year-over-year growth of 4.7%.
AON beat on earnings in each of the trailing four quarters, delivering an average surprise of 3.1%. This is depicted in the figure below.
Aon’s Accelerating Aon United (“AAU”) initiative is improving efficiency through technology streamlining, operational consolidation and better integration of its Risk Capital and Human Capital businesses. Lower AAU Program expenses and rising savings in first-quarter 2026 reflect solid execution. Management expects annual run-rate savings of $450 million by 2027, supporting margins and earnings growth.
Aon’s 3x3 Plan is strengthening its business model through AI-driven tools, analytics and operational simplification. Solutions like Broker Copilot and Aon Claims Copilot are improving client servicing and productivity. The company plans to invest nearly $1.3 billion in technology and talent by 2026 end to support long-term organic growth.
AON continues to expand its market reach through targeted acquisitions and partnerships. The NFP acquisition strengthened its middle-market presence, while deals like Griffiths & Armour and ShoreOne Insurance Managers enhanced capabilities in key markets. The company is also divesting non-core, lower-margin businesses to sharpen its focus on higher-return segments. This disciplined strategy has helped drive a trailing 12-month return on invested capital (ROIC) of 8.1%, above the industry average of 7.5%.
Aon continues to reward shareholders through share buybacks and dividend increases. In first-quarter 2026, it repurchased 1.5 million class A ordinary shares for roughly $500 million and retained around $800 million under its current authorization. The company also increased its quarterly dividend by 10% in April 2026, lifting the payout to 82 cents per share from 74.5 cents. Strong cash generation continues to support these capital deployment initiatives.
Risks to Watch
Investors should remain mindful of Aon’s leveraged balance sheet. The company exited the first quarter with cash and cash equivalents of $1.2 billion, long-term debt of $13.5 billion and short-term debt of $1.1 billion. Its long-term debt-to-capital ratio of 57.7% is notably higher than the industry average of 41.5%.
The debt-heavy balance sheet has also led to elevated interest expenses. Interest expense surged 62.8% in 2024, followed by a further 3% year-over-year increase in 2025. The metric came in at $179 million in first-quarter 2026, which continues to weigh on margin expansion. Aon’s extensive international presence makes its financial results vulnerable to fluctuations in foreign exchange rates.
Aon’s disciplined execution, ongoing efficiency initiatives and strategic investments should continue to support long-term growth and gradual deleveraging. AON currently carries a Zacks Rank #3 (Hold), reflecting balanced near-term risk and reward potential.
