Aon plc AON is making a major push to strengthen its position in the U.S. insurance brokerage market with a $17 billion acquisition of USI Insurance Services from KKR and other shareholders. USI, the 10th-largest U.S. insurance broker, generates about $3 billion in annual revenues, employs more than 10,500 people and operates nearly 200 offices across the country.
The transaction builds on Aon’s $13.4 billion acquisition of NFP in 2024 and significantly expands its footprint across the more than $40 billion U.S. middle-market segment. Expected to be closed in the fourth quarter of 2026, the acquisition will expand Aon's access to specialty insurance and the Excess & Surplus (E&S) segment while adding USI's proprietary analytics capabilities to Aon's broader data platform.
Aon expects the combination to generate around $395 million in annual net adjusted EBITDA benefits through revenues and cost synergies, with adjusted EPS expected to become accretive in 2028. The opportunity is attractive, but the transaction value leaves little room for operational missteps. Aon is paying $16.7 billion net of certain tax attributes, or about 14.5 times synergized trailing adjusted EBITDA, while funding the purchase with new debt.
Overall, this transaction is strategically strong but financially demanding. Aon is taking on more debt in exchange for a larger platform and stronger growth prospects. While the near-term suspension of share repurchases may weigh on shareholder returns, prioritizing debt repayment should improve financial flexibility. If Aon successfully integrates USI, realizes the planned synergies and steadily reduces leverage, the acquisition could become a meaningful earnings driver and create lasting value for shareholders.
