Summary
Summary of the 8-K filed January 30, 2026. Cited figures are marked; the original filing is the authoritative source.
Aon plc reported a strong close to 2025, with total revenue up 9% to $17.2 billiona for the full year and 6% organic growth, the second straight year at that organic rate.
Fourth-quarter revenue rose 4% to $4.3 billionb (5% organic). Adjusted operating margin expanded 90 basis points for the full year to 32.4%, and adjusted diluted EPS grew 9% to $17.07. Free cash flow rose 14% to $3.2 billion, supporting debt paydown and shareholder returns.
GAAP results are inflated by a one-time $1.2 billionc gain from the sale of NFP Wealth recognized in Other income. GAAP diluted EPS rose 36% to $17.02 for the year and 138% to $7.82 in the fourth quarter, but investors should focus on adjusted figures, since the gain is excluded from them. Adjusted EPS growth of 9% is the cleaner measure of underlying performance.
Management also highlighted that the company paid down $1.9 billiond of debt and met its leverage objective in Q4 2025. Looking ahead, Aon introduced 2026 guidance calling for mid-single-digit or greater organic revenue growth, 70 to 80 basis points of adjusted operating margin expansion, strong adjusted EPS growth, and double-digit free cash flow growth. Management expects a favorable currency impact of about $0.39 per share for 2026 if rates hold steady.
The company also plans to balance high-return M&A with shareholder capital returns. Watch for execution on the Accelerating Aon United restructuring program, which carried $365 million of charges in 2025, and for Health Solutions, where organic growth slowed to 2% in Q4.

03—Questions
Frequently Asked Questions
Why is GAAP EPS growth so much higher than adjusted EPS growth?
GAAP diluted EPS for full-year 2025 included a roughly $1.2 billion gain from the sale of NFP Wealth, recorded in Other income. Adjusted EPS excludes this one-time gain, along with amortization, restructuring (Accelerating Aon United), and integration costs. Adjusted EPS growth of 9% better reflects underlying operating performance.
What drove the improvement in margins?
Adjusted operating margin rose to 32.4% for the year, driven by organic revenue growth, operating efficiencies from Aon Business Services, and net restructuring savings. Risk Capital adjusted margin was 34.3%, while Human Capital improved to 32.2% from 29.5%, though part of this reflects the NFP Wealth divestiture.
What does the 2026 guidance imply for investors?
Management guided to mid-single-digit or greater organic revenue growth, 70-80 bps of adjusted margin expansion, strong adjusted EPS growth, and double-digit FCF growth. Aon does not provide a reconciliation of forward non-GAAP measures, so the specific EPS and margin figures are not quantified. Currency is expected to add about $0.39 per share in 2026 if current rates hold.
How is Aon using its cash flow and balance sheet?
In 2025 Aon generated $3.2 billion of free cash flow and used it to repay $1.9 billion of debt and return about $1.6 billion to shareholders through $1.0 billion of buybacks and $629 million of dividends. About $1.3 billion of repurchase authorization remains. Management says the strengthened balance sheet will support both high-return M&A and continued capital returns in 2026.
Are there any areas of concern in the results?
Health Solutions organic growth slowed to 2% in Q4 2025, reflecting softer discretionary Talent Solutions spend and delayed closed sales. Accelerating Aon United program expenses rose 87% in Q4 to $129 million due to workforce optimization costs. Fourth-quarter Wealth Solutions revenue declined 10% reported, largely due to the NFP Wealth sale, though organic growth was 2%.
