Material Changes vs. Prior Period
- Revenue Growth: Q3 2025 revenue increased 7% ($276 million) driven by 7% organic growth and favorable currency impacts. Year-to-date revenue increased 12% ($1.3 billion), reflecting the full contribution of the NFP acquisition and 6% organic growth.

- Risk Capital: Revenue up 7% in Q3 and 8% YTD. Operating margin decreased slightly to 23.2% in Q3 from 23.8% prior year.
- Human Capital: Revenue up 8% in Q3 and 20% YTD. Operating margin expanded significantly to 22.5% in Q3 from 14.8% prior year, driven by lower transaction costs and strong Health/Wealth performance.

Guidance, Outlook, and Risks
- Outlook: Management expects the AAU program to generate annualized expense savings of approximately $350 million by the end of 2026. The company anticipates sufficient distributable profits (exceeding $30.5 billion) to fund dividends and share repurchases.
- Divestiture: On September 3, 2025, Aon signed an agreement to sell a significant majority of NFP's wealth business (including Wealthspire Advisors) to Madison Dearborn Partners. The transaction closed on October 30, 2025, with proceeds of $2.3 billion. The gain will be recognized in Q4 2025.
- Share Repurchases: The company repurchased 0.7 million shares in Q3 2025 at an average price of $362.00. Approximately $1.6 billion remains authorized under the repurchase program.
- Risks:
- Legal Contingencies: Ongoing litigation related to the Vesttoo Ltd. fraudulent letters of credit matter. A $23 million reduction in legal settlement expenses was recognized in Q3 2025.
- Geopolitical & Economic: Exposure to global conflicts, tariffs, inflation, and currency fluctuations.
- Tax: Uncertainty regarding the implementation of the OECD Pillar Two global minimum tax regime.
Investor Verification Checklist
- NFP Integration: Verify the realization of anticipated synergies and the impact of increased amortization on future margins.
- Wealth Business Sale: Confirm the final gain recognition amount and timing in Q4 2025 financials following the October 30 closing.
- Restructuring Savings: Monitor progress toward the $350 million annualized savings target from the AAU program.
