AON Announces $17 Billion Acquisition of USI Insurance Services, Stock Drops
Aon plc (NYSE: AON) announced its plan to acquire USI Insurance Services from KKR and other shareholders for approximately $17 billion. The deal is expected to significantly expand Aon’s presence in the U.S. middle-market by adding risk management, health insurance, and retirement services businesses that generate around $3 billion annually. While positive long-term synergies are anticipated—such as an estimated $395 million annual run-rate net adjusted EBITDA boost—the stock dropped sharply due to concerns over increased leverage from financing the acquisition with new debt. Investors appear focused on balance-sheet risks and integration challenges, overshadowing potential future earnings growth. The transaction is expected to close in Q4 2026 after regulatory approvals are secured. USI’s CEO will join Aon as president of its Middle Market division.
