Bond financing for USI takeover reshapes balance sheet
According to Bloomberg on September 14, 2026, Aon raised USD 13.5 billion through a multi tranche US dollar bond offering to help finance its planned acquisition of USI Insurance Services, making it one of the largest merger financing transactions in 2026.
As Insurance Journal reported on September 15, 2026, most of the bond tranches include a change of control style clause that requires Aon to redeem the notes at 101% of face value plus accrued interest if the USI deal is not completed by December 1, 2027, underscoring that the financing is tightly linked to closing the acquisition.
Analyst price targets support Aon plc stock above 300 USD
According to MarketBeat on September 14, 2026, TD Cowen raised its price target on Aon from USD 416.00 to USD 420.00 and maintained a Buy style recommendation, while MarketBeat data show an average rating of Moderate Buy with a consensus price target of USD 399.35.
The same MarketBeat overview notes that Aon shares traded at USD 307.00 during mid day trading on September 14, 2026, with around 490,700 shares changing hands compared with an average daily volume of about 1,449,600 shares, indicating that the stock price of a little above USD 300 remains below the USD 399.35 consensus target by roughly 30% in absolute dollar terms.
Recent earnings trends frame the financing move
In its most recent quarterly reporting period for the second quarter of 2026, Aon reported mid single digit revenue growth compared with the prior year quarter and an increase in earnings per share, according to company information summarized on its investor relations materials as of August 2026.
For that Q2 2026 period, Aon indicated that total revenue grew versus the same quarter a year earlier while earnings per share grew at a faster pace due to operating leverage and share repurchases, providing a fundamental backdrop for the decision to commit USD 13.5 billion of new bond financing for the USI transaction.
