KKR has agreed to sell USI Insurance Services to insurer Aon for $17 billion, resulting in one of the largest gains ever recorded by a publicly traded private equity firm on a single transaction. The New York-based investment group will receive approximately $3.3 billion in after-tax cash from the deal, representing a return of roughly 3.4 times its initial investment of nearly $1 billion made in 2017.

This transaction highlights a rare success for private equity in 2024, a year marked by a broader slowdown in the industry, with investors holding a record $4 trillion in aging assets. Alongside firms like Advent International and Blackstone, KKR has managed to exit investments with substantial profits despite challenging market conditions.

The sale significantly boosts KKR’s adjusted net income by an estimated $2 billion, or about $2 per share. Unlike many of its peers, KKR has pursued a distinctive strategy of deploying substantial amounts of its own capital into deals rather than relying primarily on funds raised from outside investors. This approach has positioned the firm to capture a greater share of returns directly, rather than mainly depending on performance fees charged to limited partners.

Typically, private equity firms buy companies using capital from institutional investors and generate revenue through management and performance fees, often around 20 percent of profits exceeding an 8 percent annual benchmark. This model, pioneered by KKR co-founders Henry Kravis and George Roberts, contributed to the growth of private equity’s influence in public markets following the 2008 financial crisis. However, investors often favored such firms because they earned profits without significant personal capital at risk.

After listing on the New York Stock Exchange in 2010, KKR sought to supplement its fee-based income by increasingly investing its own funds into select deals. Initial uses of this capital included stabilizing acquisitions such as First Data and expanding into new sectors like infrastructure, along with purchases such as insurer Global Atlantic in 2020. In 2024, KKR co-chief executives Scott Nuttall and Joseph Bae refined this approach by establishing a "strategic holdings" unit, currently managing more than $10 billion across nearly two dozen investments expected to appreciate and deliver growing dividends.

The windfall from the USI sale rivals some of the largest private equity profits in recent history, comparable to Blackstone’s sale of Hilton Hotels and Apollo’s disposal of chemicals firm LyondellBasell over a decade ago. However, USI operates in a specialized segment of the insurance industry and generates about $3 billion in annual revenues, making it less well-known outside its niche.

Nuttall and Bae described the USI transaction as a “monetization milestone” that confirms the value of KKR’s portfolio strategy. They emphasized the portfolio's potential for "durable, growth-oriented and recurring cash flows,” underscoring confidence in the firm’s investment approach as it continues to deploy proprietary capital in pursuit of long-term gains.
