Over the course of KKR's ownership, USI's adjusted revenues and adjusted EBITDA grew at compounded annual growth rates of approximately **12% and 13%** , respectively . The firm supported significant investments in USI's people, platform, and technology to scale the business .

## The Deal's Strategic Rationale

It follows Aon's own $13.4 billion acquisition of NFP Corp. in 2024 .
