"Our Aon United strategy continues to advance and differentiate our platform for clients," said Greg Case, President and CEO of Aon. "As we progress through the final year of our 3x3 Plan, our investments in AI-enabled analytics, innovative capabilities and capital solutions, and leading experts are helping clients address their risks, build resilience and drive better outcomes. At the same time, we are strengthening our context advantage and expanding our ability to serve clients across a broader market through the announced acquisition of USI, while creating new opportunities through greater access to both traditional and alternative sources of capital."
Aon expects the USI acquisition to close in the fourth quarter of 2026. It will then prioritise debt repayment, aiming to reach its leverage objective of 2.8x to 3.0x in approximately 24 months.
The company did not repurchase any shares in the third quarter. Approximately $7.7bn of repurchase authorisation remained as of 30 September 2026.
