Aon to Acquire USI Insurance Services in $17 Billion Deal from KKR
Aon said on Monday it will buy rival USI Insurance Services in a US$17 billion deal from private equity firm KKR, marking one of the largest insurance brokerage transactions in recent years. The acquisition is expected to close in the fourth quarter of 2026 and is anticipated to boost Aon's adjusted profit in 2028.
The deal underscores Aon's push to expand in the S. middle-market insurance segment, which serves mid-sized businesses and is estimated at more than $40 billion. Aon CEO Greg Case said the combination "will establish the premier S. middle-market platform, deepen our context advantage and position Aon to accelerate organic growth." He added that "building on the success of our acquisition of NFP, USI will substantially enhance our middle-market footprint and expand access for our firm in the E&S (excess & surplus) segment."
USI, founded in 1994, is an insurance brokerage and consulting firm based in Valhalla, New York. It offers property and casualty, employee benefits, personal risk, program and retirement services, and generates about $3 billion in annual revenue. Under KKR's ownership, the firm nearly tripled its revenue, according to KKR.
The acquisition builds on Aon's $13 billion purchase of NFP in 2024. Aon, which caters to clients in over 120 countries, expects to fund the deal through debt. USI CEO Mike Sicard will serve as Aon's president and global CEO of its middle-market segment.
For KKR, the transaction adds to a pickup in exit activity. The second quarter was the largest monetization quarter in its history, and the USI deal is expected to generate roughly $2 billion of adjusted profit for KKR. KKR said the sale represents about six times return on its 2017 investment and a 3.4 times return on the capital invested over the life of its investment in USI.
BofA Securities and Citi advised Aon on the deal, while Goldman Sachs, Insurance Advisory Partners and Morgan Stanley advised KKR.

AI-extracted; can misattribute a claim — see Methodology.
Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
