Aon is nearing a deal to acquire insurance brokerage and consulting firm USI from KKR at a value of roughly $17 billion including debt, according to a Wall Street Journal report relayed Sunday by CNBC and PYMNTS. The prospective transaction would put a large middle-market-focused broker in the hands of one of the industry’s biggest consolidators.
The report is significant both for its size and for what it says about the continuing value assigned to scaled insurance-distribution businesses. But it remains a reported transaction rather than a completed acquisition: the follow-up accounts attribute the central terms to the Journal’s unnamed sources, and neither account identifies a public statement or filing from Aon, KKR or USI. The companies could announce an agreement as soon as Aug. 31 if final terms are settled, the reports said.
What the reported $17 billion figure means
The reported price is an enterprise value, not necessarily the amount Aon would pay directly to USI shareholders. Because it includes debt, the $17 billion figure combines the value of the company’s equity with its debt obligations, less cash where applicable. The reports do not disclose USI’s debt balance, the equity purchase price, the form of consideration or financing terms.
That distinction limits what can be inferred about the buyer’s capital commitment. Still, the reported number offers a useful scale measure. CNBC said USI has about $3 billion of annual revenue, citing the company’s website. On those reported figures, the proposed enterprise value would equal roughly 5.7 times annual revenue. That is a broad valuation comparison, not a profitability multiple: the available accounts give no EBITDA figure, organic-growth rate or debt detail needed to judge the economics of a final agreement.
USI, based in Valhalla, New York, provides insurance brokerage and consulting services spanning risk management, employee benefits and retirement needs. The Journal’s reporting, as summarized by CNBC, indicated that the business would increase Aon’s reach with midsize companies and could add to Aon’s earnings per share as early as 2028. That anticipated earnings timetable is also conditional on a deal being reached and closed.
A reported exit after KKR’s long USI investment
A sale would mark a substantial potential exit for KKR, which has been associated with USI since 2017. The ownership history requires some care because the two follow-up accounts describe it differently. CNBC said KKR bought USI from Onex in 2017 and increased its ownership stake in 2023, becoming the company’s largest shareholder. PYMNTS, also citing the Journal, said KKR acquired USI alongside Canadian investment manager CDPQ in a 2017 transaction valued at $4.3 billion.
Those descriptions may not be inconsistent: a buyer group can acquire a company from a prior owner and subsequently change the size of its individual partners’ stakes. But the available reporting does not provide the underlying ownership documents or the exact structure of KKR’s 2023 increase. The defensible conclusion is narrower: KKR has been a major USI investor for years, while the reported $17 billion transaction value would be far above the $4.3 billion value PYMNTS attributes to the 2017 deal.
Using those reported enterprise values as directional markers, USI’s indicated value would have risen by about $12.7 billion, or nearly four times the 2017 figure. That is not a calculation of KKR’s investment return. It excludes additional capital contributions, changes in ownership percentages, debt paydown or issuance, dividends and any proceeds owed to other shareholders.
Terms and closing remain unresolved
The deal reports point to a transaction that was close to finalization, not one already signed. CNBC and PYMNTS both trace the core claim—the buyer, seller, target and approximate debt-inclusive valuation—to the Wall Street Journal. Their coverage therefore corroborates how the Journal’s report was received, but does not constitute separate confirmation that definitive documents have been executed.
Several consequential details remain unreported in the cited accounts: whether Aon would pay in cash, stock or a combination; how much USI debt would be assumed or refinanced; whether CDPQ would sell; and what closing conditions would apply. The reports also provide no information on any regulatory review timetable.
For Aon, the attraction described in the reporting is expanded exposure to midsize clients through a business with reported annual revenue near $3 billion. For KKR, the transaction would potentially crystallize the value of an investment first made in 2017. Whether those objectives produce a signed agreement will determine whether the $17 billion figure becomes a deal value rather than another marker of brokerage-sector appetite.
