Q3 Revenue Up 3% to $4.1B
Total revenue rose to $4,101 million from $3,997 million, driven by 6% organic growth and partly offset by a 3% divestiture drag from the NFP Wealth and Stroz Friedberg sales.

EPS Grows but Operating Income Slips
Diluted EPS was $2.23 versus $2.11, yet operating income fell $7 million to $809 million as Accelerating Aon United expenses jumped to $93 million from $32 million; adjusted operating margin still improved to 27.0% from 26.3%.

Analysis · AON · Finance
Aon's third quarter was solid but not spectacular: revenue grew 3% to $4.1 billion on 6% organic growth, while operating income slipped $7 million to $809 million as Accelerating Aon United charges nearly tripled to $93 million. The bigger story is the balance sheet. Total debt rose $12.8 billion to $28.0 billion after the $13.5 billion September note sale and $4.0 billion delayed draw term loans, with the cash parked in short-term investments until the $17 billion USI acquisition closes, now expected in the fourth quarter of 2026 subject to regulatory approval. Rating agencies have already reacted: S&P moved its A- outlook to Negative and Fitch put BBB+ on Watch Negative. Nine-month adjusted diluted EPS of $13.66 versus $12.22 shows the core franchise is still compounding, but the leverage step-up and pending integration are what will drive the stock from here.
