Aon is proceeding with a significant bond sale to finance its $17 billion acquisition of USI Insurance Services from KKR & Co. The company is offering $13.5 billion in senior notes, maturing between 2029 and 2056, to help cover the purchase price and repay USI's existing debt of approximately $4.3 billion. This debt issuance, combined with a new $4 billion term loan facility, is intended to fund the "Cash Consideration" of the deal and associated fees.
The acquisition, which values USI at 14.5 times its adjusted EBITDA (or 22 times without projected synergies), has raised investor eyebrows, leading to a 7% drop in Aon's share price and a $5 billion market value loss. Concerns center around the dramatic increase in Aon's debt load, which will almost double to nearly 4.8 times adjusted EBITDA, and the immediate suspension of share buybacks to prioritize debt reduction. Analysts from Piper Sandler, BMO Capital, and Mizuho have lowered their price targets, anticipating earnings dilution through 2027, with accretion not expected until 2028 at the earliest.
To mitigate risks, some of the notes, specifically the "USI Acquisition Notes," include a special mandatory redemption clause. If the USI acquisition is not finalized by June 1, 2027 (with potential extensions), Aon will be required to redeem these notes at 101% of their principal amount, plus accrued interest. The deal aims to establish a premier U.S. middle-market insurance platform and Aon plans to achieve a leverage ratio between 2.8:1 and 3.0:1 within approximately 24 months post-acquisition. USI reported approximately $3 billion in annual revenue and $756 million in adjusted EBITDA for the twelve months ended June 30, 2026.
