Aon in Advanced Talks to Acquire USI Insurance Services in ~$17B Deal
Deal talks between Aon plc and KKR-backed USI Insurance Services are in their final stages, with an announcement potentially imminent, according to reporting from CNBC and Bloomberg. The acquisition, valued at approximately $17 billion including debt, would further consolidate the insurance brokerage sector and extend Aon’s aggressive midmarket expansion.
USI, based in Valhalla, NY, generates roughly $3 billion in annual revenue—a valuation multiple of approximately 5.7x sales. KKR acquired the brokerage alongside partner CDPQ from Onex in 2017 for $4.3 billion. This transaction would mark Aon’s second major scaling initiative in P&C brokerage since 2024, following its $13 billion acquisition of NFP in 2024.
For real-estate professionals, the consolidation carries operational significance: expanded Aon presence could shift which insurance brokers referral networks prioritize for client transactions, and the rate-pressure from enterprise acquisitions occasionally extends into client-facing policy pricing as operational integration costs are absorbed across the enlarged organization.
