Aon's $17 billion purchase of USI Insurance Services gives KKR a rare, self-disclosed look at what a full-cycle private equity exit actually returns.
Aon has agreed to acquire USI Insurance Services from KKR-managed funds for approximately $17 billion in an all-cash deal expected to close in the fourth quarter, pending regulatory approval. KKR first invested in USI in 2017 at an entry valuation of about $4.3 billion and made three additional investments in the company over the life of the holding.
The disclosure alongside the deal is unusual. KKR said it expects a 6.0x return multiple on its original 2017 equity investment and a 3.4x return multiple on all the balance-sheet capital it put into USI over nine years, translating into roughly $3.3 billion of after-tax proceeds and about $2 billion in adjusted net income once the deal closes. Sponsors rarely attach a specific, quantified return figure directly to an exit announcement rather than leaving it for a later investor letter.
During KKR's ownership, USI's revenue nearly tripled, the company made more than 90 acquisitions, and its headcount roughly doubled to more than 10,500 employees. USI is now the 10th-largest U.S. insurance brokerage by revenue. Its chief executive, Mike Sicard, is expected to become Aon's president and global middle-market CEO once the deal closes.
The transaction also says something about KKR's newer capital structure. USI sat inside KKR's Strategic Holdings unit, a permanent-capital vehicle the firm created in 2023 to hold assets for longer stretches outside its traditional fund cycle. This sale shows that even a "permanent capital" label doesn't prevent an asset from being sold once a sufficiently attractive buyer appears, a detail worth watching as more of that capital matures.
The return figures are KKR's own, self-reported ahead of a transaction that hasn't closed, and haven't been independently audited. They are the seller's disclosed math on a real, dated, all-cash deal, not a verified final accounting.
