Aon Nears $17 Billion Acquisition of Insurance Brokerage USI from KKR
Insurance giant Aon is reportedly on the verge of finalizing a deal to acquire the insurance brokerage firm USI from private-equity powerhouse KKR. The transaction, which is valued at approximately $17 billion including debt, could be officially announced as early as Monday, according to reports.
The potential move marks a significant expansion for Aon, a global leader in risk management and consulting with a market capitalization of $75 billion. By integrating USI—a Valhalla, New York-based firm specializing in risk management, employee benefits, and retirement consulting—Aon aims to deepen its footprint within the midsize business sector. Sources familiar with the negotiations suggest that the acquisition is expected to be accretive to Aon’s earnings per share by 2028.
Strategic Shift for KKR
For KKR, the sale represents a successful conclusion to a long-term investment. The private-equity firm first acquired USI from Onex in 2017. Following years of growth, KKR solidified its position as the brokerage’s majority stakeholder in 2023.
This potential divestiture aligns with a broader trend of high-profile exits for KKR this year. The firm has recently offloaded assets such as the data-center cooling company CoolIT and the aerospace business of Circor. These strategic moves have paid off; in the quarter ending in June, KKR reported a record $1.29 billion in asset sales, signaling a robust environment for private-equity realization.
Market Context
Aon’s pursuit of USI comes as the firm navigates a fluctuating market. On July 29, the company reported strong second-quarter performance, delivering adjusted earnings of $3.81 per share, which surpassed consensus Wall Street estimates. Despite the positive earnings report, Aon shares have faced headwinds, declining 5.6% since that announcement to close at $355.40 on Friday.
As the industry watches for the formal confirmation of this [17 billion deal] (https://www.cnbc.com/2026/08/30/aon-usi-17-billion-deal-talks.html), analysts will be scrutinizing whether the integration of USI’s $3 billion in annual revenue will provide the long-term growth trajectory Aon needs to bolster its stock performance and fend off competitive pressures in the brokerage space.
Neither Aon nor KKR has provided an official statement regarding the reported negotiations.
