Aon will buy rival USI Insurance Services in a $17 billion deal from private equity firm KKR, the insurance brokerage said on Monday.
Mega buyouts have become more typical in the highly fragmented insurance brokerage industry in recent years as companies turn more willing to pay top dollar to bolster their market presence and competitive edge.
Founded in 1994, USI is an insurance brokerage and consulting firm which offers property and casualty, employee benefits, personal risk, program and retirement services.
The USI deal is expected to close in the fourth quarter of 2026.
