Aon Acquisition Shock: Why The $17 Billion USI Deal Could Reshape Insurance!

Aon plc has taken another major step in its push into the U.S. middle market, entering a definitive agreement on August 31, 2026, to acquire USI Insurance Services in an all-cash transaction valued at approximately $17 billion, or $16.7 billion after certain tax attributes. The transaction, which is expected to close in the fourth quarter of 2026 subject to regulatory approvals and customary conditions, follows Aon’s 2024 acquisition of NFP and would significantly enlarge its presence among midsize U.S. businesses. USI brings roughly $3.3 billion of revenue, a large producer network and substantial property-and-casualty premium placement, while also giving Aon deeper exposure to specialty insurance distribution. Management has identified $395 million of potential adjusted EBITDA synergies across the broader Aon, NFP and USI platform.
