Summary
Summary of the 8-K filed October 31, 2025. Cited figures are marked; the original filing is the authoritative source.
Aon plc reported third quarter 2025 results on October 31, 2025, showing another quarter of solid top-line and earnings growth.
Total revenue rose 7% to $4.0 billiona, with 7% organic growth (1% favorable FX, offset by a 1% unfavorable impact from acquisitions, divestitures and other items). Risk Capital revenue grew 7% to $2.5 billion and Human Capital grew 8% to $1.5 billion. GAAP operating margin expanded to 20.4% from 16.7%, though this was flattered by lower Accelerating Aon United restructuring costs and the prior-year base.
Adjusted operating margin improved 170 basis points to 26.3%, and adjusted EPS rose 12% to $3.05b. GAAP diluted EPS increased 34% to $2.11, helped by lower operating expenses and a non-recurring comparison. Cash generation remained strong, with operating cash flow up 13% to $1.15 billion in the quarter and free cash flow up 13% to $1.08 billion.
For the first nine months, free cash flow reached $1.9 billionc. Aon repurchased about $250 million of shares in the quarter and had roughly $1.6 billion of authorization remaining. Management reiterated confidence in achieving full-year 2025 financial targets and said it expects sustainable growth into 2026.
Key watch items for investors include the rising organic growth in Health Solutions and Reinsurance, the pace of NFP integration (which contributes to acquisition-related revenue and cost dynamics), the effective tax rate rise to 21.3% GAAP and 19.2% adjusted, and the reduction in interest expense as total debt declined. Quarter-end total debt was roughly $16.8 billiond, down from about $17.0 billion at year-end 2024. Note that the filing also indicates a pending divestiture: a significant majority of NFP's Wealth business was classified as held for sale in September 2025.

03—Questions
Frequently Asked Questions
Did Aon meet its growth expectations in Q3 2025?
Aon reported 7% total and organic revenue growth in Q3 2025 and 12% total revenue growth for the nine months (6% organic). Adjusted EPS grew 12%. Management reiterated its full-year 2025 guidance, indicating the company expects to meet its targets.
How much of the margin improvement is structural versus one-time?
Adjusted operating margin rose 170 bps, supported by organic growth, ABS scale efficiencies, and net restructuring savings of $35 million, partly offset by investment in long-term growth. The GAAP margin gain was larger because restructuring costs and integration costs fell year over year, which investors should treat as partly non-recurring.
Why did GAAP EPS rise faster than adjusted EPS?
GAAP diluted EPS rose 34% to $2.11 versus a prior-year $1.57, while adjusted EPS rose 12%. The gap reflects prior-year items, including gains from business sales in 2024 and higher amortization in 2025, along with lower Accelerating Aon United and integration costs. Investors should focus on adjusted EPS for comparability.
Is Aon's balance sheet and cash flow supporting shareholder returns?
Operating cash flow was $2.1 billion for nine months (up 14%), and free cash flow was $1.9 billion. Aon repurchased $750 million of shares year-to-date (per the cash flow statement) and paid $468 million in dividends, with about $1.6 billion of authorization remaining. Total debt declined, with interest expense down $7 million year over year in the quarter.
What are the main risks or open items highlighted in the filing?
The filing references the ongoing NFP integration and integration costs, the Accelerating Aon United restructuring program, the effective tax rate increase to 21.3% GAAP (19.2% adjusted), and the held-for-sale classification of a significant majority of NFP's Wealth business. It also flags legal settlements, regulatory matters, and FX and market-related risks.
