Aon is reported to be nearing a roughly $17 billion agreement to acquire USI Insurance Services, a rival insurance broker backed by KKR. Multiple outlets cite reporting from The Wall Street Journal, and say the transaction is close to final terms.
The reports describe the deal as an all-cash purchase and indicate it could be announced as early as Monday, according to the New York Post. Quartz adds that the transaction is expected to close in the fourth quarter of 2026, and that USI CEO Mike Sicard would become president of Aon after the acquisition. Other coverage focuses more on market reaction: Seeking Alpha reports that Aon shares fall sharply following news of the proposed $17 billion deal.
While most sources converge on the headline size, counterparty, and structure, they differ mainly in emphasis—timing of announcement, leadership role after closing, expected closing window, and investor reaction to the news rather than on new deal terms.
