Insurance broker Aon announced on Monday that it had agreed to purchase rival USI Insurance Services from private equity firm KKR in an all-cash deal worth around $17bn.
The transaction was unanimously approved by the boards of directors of both Aon and USI and is expected to close in the fourth quarter of 2026.
Acquiring USI is expected to boost Aon’s adjusted profit in 2028. Aon plans to fund the deal through debt and does not expect near-term share buybacks as it prioritises debt repayment. The deal is expected to deliver $395m in annual run-rate net adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) impact from revenue and cost synergies across the combined middle-market platform and to be accretive to adjusted earnings per share in 2028. The net purchase price represents approximately 14.5x on a synergised trailing 12-month adjusted EBITDA basis, according to Aon.
Following the close of the transaction, Mike Sicard, chairman and chief executive of USI, will serve as president of Aon plc and global chief executive of middle market and join the Aon executive committee.
“In a time of rising complexity and volatility, creating better outcomes for clients across their risk and people challenges requires a combination of capabilities and expertise supported by proprietary data, analytics and technology,” said Greg Case, president and chief executive of Aon. “Through the successful execution of our 3x3 Plan to accelerate our Aon United strategy, we have significantly strengthened our firm to build the industry’s most differentiated model: what we call our context advantage.
“Combining with USI will establish the premier U.S. middle-market platform, deepen our context advantage and position Aon to accelerate organic growth,” he continued. “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 segment to deliver content, capabilities and expertise to a broader client base, while enabling client leaders to expand relationships and win new business. Our combined data platform will generate richer insight, advance the development of innovative, AI-driven solutions and expand the universe of insurable risk, while further reinforcing the context advantage that differentiates Aon.”
“Joining Aon represents a truly energising next chapter for our firm and an opportunity to accelerate our momentum as part of the Aon United platform,” said Mr Sicard. “Our firms share strong, one-firm cultures with a deep commitment to working together to bring the best of our capabilities to clients.”
USI, a leading provider of property & casualty, employee benefit, personal risk and retirement solutions for the middle market, is the 10th largest US insurance broker with approximately $3bn in annual revenue and more than 10,500 team members across nearly 200 US offices.
As USI’s largest shareholder, KKR said that it expects to recognise approximately $3.3bn of after-tax proceeds and about $2bn of adjusted net income. Under KKR’s ownership, USI nearly tripled its revenue and made more than 90 acquisitions, according to KKR.
