Aon Acquires USI for $17 Billion to Strengthen U.S. Middle-Market Platform
Aon has signed a definitive agreement to acquire USI, the tenth-largest insurance broker in the United States, for $17 billion. The deal is expected to significantly expand Aon's presence in the growing middle-market segment and enhance its capabilities through access to new data platforms and expertise in Excess & Surplus (E&S) commercial insurance. This acquisition follows Aon’s 2024 purchase of NFP, furthering a strategy aimed at building an industry-leading platform. USI brings approximately $3 billion in annual revenue and over 10,500 employees across nearly 200 U.S. offices to the deal.
