Aon stated that the acquisition is intended to expand its service capabilities for midsize businesses. The global professional services firm projects that the deal will be accretive to its earnings per share by 2028.
AdMarket Reaction and Context
Following the news, shares of Aon dropped 1.8% in Monday's premarket session. The transaction represents a significant exit for KKR, which is working through a backlog of assets amid a shifting private-equity landscape.
KKR, along with Canadian investment firm CDPQ, first acquired USI from private-equity firm Onex in 2017 for $4.3 billion. KKR has since made additional investments to become the company's largest shareholder. The sale aligns with KKR's recent activity, as the firm reported its best-ever quarterly asset sales of $1.29 billion in the latest period.
