Aon reports 6 percent organic growth while Aon stock stays near Xetra close

Aon plc (ISIN IE00BLP1HW54) delivered 6 percent organic revenue growth in the third quarter of 2026. According to Aon on October 28, 2026, the result came with broader expansion across its business lines and a higher adjusted margin.

Growth outpaced reported revenue

Total revenue increased 3 percent to USD 4.10 billion for the three months ended September 30, 2026. The difference between reported and organic growth reflected a 3 percent unfavorable impact from divestitures, while Risk Capital revenue rose 6 percent to USD 2.68 billion.

Commercial Risk Solutions and Reinsurance Solutions each posted 7 percent organic growth. Health Solutions grew 6 percent organically, while Wealth Solutions delivered 4 percent organic growth after portfolio changes. The mix points to continued demand in the core risk businesses, even as divestitures reduced the reported group figure.

What does the margin mean?

Adjusted operating income increased 5 percent to USD 1.11 billion, and adjusted earnings per share rose 10 percent to USD 3.36 in the third quarter. Aon said the margin improvement reflected organic growth, scale benefits in Aon Business Services and restructuring savings, partly offset by investments for growth.

USI adds a balance-sheet test

Aon expects the USI acquisition to close in the fourth quarter of 2026. The company plans to prioritize debt repayment afterward and aims to return to a 2.8 to 3.0 times leverage objective within about 24 months; third-quarter long-term debt was USD 26.32 billion.
