Business Context and Reporting Period

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Q2 revenue increased 2% ($91 million) and YTD revenue increased 4% ($396 million). Growth was driven by 5% organic revenue growth and favorable foreign currency translation, partially offset by a 4% negative impact from divestitures (primarily the NFP Wealth business).
• Segment Performance:
  • Risk Capital: Revenue increased 5% in Q2 and 7% YTD. Operating margin improved to 30.5% (Q2) and 35.3% (YTD).
  • Human Capital: Revenue decreased 4% in Q2 and 2% YTD due to the NFP Wealth divestiture. However, operating margin expanded significantly to 13.4% (Q2) and 21.9% (YTD) due to cost savings and lower amortization.
• Profitability: Operating income increased 6% in Q2 and 13% YTD. Net income attributable to shareholders decreased 5% in Q2 due to a $73 million decrease in "Other income (expense)" (absence of prior-year deferred consideration gains), but increased 14% YTD.
• Expenses: Operating expenses increased 1% in Q2 and 1% YTD, driven by organic growth and technology investments, offset by $25 million (Q2) and $50 million (YTD) in net restructuring savings from the Accelerating Aon United (AAU) Program.

Guidance, Outlook, and Risks

• Restructuring (AAU Program): The three-year program is expected to result in cumulative costs of $1.3 billion. As of June 30, 2026, $1.077 billion has been incurred. The program is estimated to generate annualized expense savings of approximately $450 million by the end of 2027.
• Capital Allocation: The company repurchased $1.1 billion of shares YTD. As of June 30, 2026, approximately $7.7 billion remains authorized for repurchases. A dividend of $0.820 per share was declared for payment in August 2026.
• Legal Contingencies:
  • Vesttoo Matters: Ongoing litigation regarding fraudulent letters of credit. Aon recognized $197 million in settlement expenses in late 2023, reduced by $23 million in Q3 2025. Aon intends to vigorously defend against remaining claims.
  • Aviation Crash: Litigation related to a 2016 Bolivian airline crash involves claims totaling up to $844 million in the U.S. and $16.7 million in the UK. Aon believes it has meritorious defenses.
• Tax Risks: The effective tax rate was 22.0% in Q2 and 20.8% YTD. Future rates may be impacted by the OECD Pillar Two global minimum tax regime.

Investor Verification Checklist

• Organic Growth Sustainability: Verify the 5% organic revenue growth rate across both Risk Capital and Human Capital segments, particularly given the headwinds from divestitures.
• Restructuring Savings Realization: Monitor the realization of the projected $450 million in annualized savings from the AAU program against the remaining cash charges.
• Legal Exposure: Assess the potential financial impact of the Vesttoo litigation and the Bolivian aviation crash claims, noting that Aon is self-insured for some claims.
• Debt Maturity Profile: Review the repayment schedule for the $1.72 billion in debt classified as current (due within one year), including the 2.850% and 5.125% Senior Notes due in 2027.
• Non-GAAP Reconciliations: Review the reconciliation of Adjusted Operating Margin (28.9% Q2) and Adjusted Diluted EPS ($3.81 Q2) to understand the impact of excluded items like amortization and restructuring costs.
