Aon agrees to buy USI: what it means for USI stock

USI Corporation (ISIN TW0001304004) became the target of a USD 17.00 billion acquisition after Aon agreed to buy the company from KKR and other shareholders on September 1, 2026, MarketScreener reported. The transaction is expected to close in the fourth quarter of 2026, subject to customary conditions and regulatory approvals.

Deal value sets the frame

The agreed purchase price gives the transaction a clear financial anchor for USI shareholders. Aon plans to fund the acquisition with new debt, while the two companies are expected to operate independently until closing, according to MarketScreener on September 1, 2026.

The deal also places USI's operating profile beside its valuation. MarketScreener describes USI as a provider of property and casualty insurance solutions, employee benefits, personal risk management and retirement services for middle-market clients, with annual revenue of USD 3.00 billion and more than 10,500 employees across nearly 200 US offices.

Second-quarter figures show pressure

USI's latest reported figures show a mixed operating picture. Investing.com reports revenue of TWD 11.01 billion in the latest quarter, up from TWD 10.75 billion in the previous quarter, a 2.48 percent increase. Net income was TWD -178.88 million.

Winvest reports second-quarter 2026 earnings per share of TWD -0.17, up 59.00 percent quarter over quarter and 79.00 percent year over year. The loss makes the acquisition terms and closing timetable more important reference points than a simple revenue comparison.
