The Ardonagh Group, an independent insurance distribution platform based in London, has announced the successful completion of a $2.5 billion equity investment spearheaded by funds managed by Stone Point Capital LLC, a private equity firm based in the United States.

The deal, which places Ardonagh’s valuation at $14 billion, saw overwhelming interest from co-investors linked to Stone Point, as well as partners from Madison Dearborn Partners (MDP) and HPS Investment Partners (HPS).

Stone Point has emerged as a major shareholder in Ardonagh, joining the ranks of MDP, HPS, and other global institutional investors, including a wholly owned subsidiary of the Abu Dhabi Investment Authority (ADIA).

With this diversified investor base, Ardonagh is poised to capitalize on a variety of growth opportunities within the global property and casualty (P/C) insurance market through its extensive platform of businesses, each with a robust regional market presence.

Founded in 2017, Ardonagh was created by merging several UK insurance businesses, which gave rise to a diversified group offering wholesale, retail, and specialist insurance solutions. Since its formation, Ardonagh has evolved into a top-20 global broking entity, placing approximately $18 billion in premiums and operating throughout the entire insurance distribution value chain.

The closing of this investment comes on the heels of several key developments in Ardonagh’s growth trajectory, including a number of strategic acquisitions in 2024. The company completed the sale of its personal lines business to Markerstudy in June 2024, followed by the A$2.3 billion take-private of Australia’s PSC Insurance Group in October 2024. These transactions were part of a broader effort to complete 68 acquisitions across multiple regions within that year.

More recently, Ardonagh simplified its capital structure through a successful refinancing in February 2025. In March 2025, the group launched Ardonagh Intelligence, marking a new phase in its strategy to leverage machine learning and data enrichment across its businesses to deliver enhanced value to its vast customer base.

David Ross, CEO of The Ardonagh Group, commented on the deal: “Stone Point’s investment, alongside the success of the co-investment process, is a powerful vote of confidence in Ardonagh. In the face of global economic challenges, our distinctive proposition, proven track record, and global platform attracted world-class investors who share our long-term vision.”

Ross added, “We are thrilled to welcome Stone Point into this next chapter of our growth, along with our long-standing partners whose support has been instrumental in helping us reach a $14 billion valuation. With such robust financial backing, Ardonagh is uniquely positioned to seize future growth opportunities and continue delivering value for our clients, investors, and employees.”

Jim Carey, co-CEO of Stone Point, shared his enthusiasm: “We are excited to partner with Ardonagh, alongside MDP, HPS, and ADIA. Ardonagh has emerged as a prominent platform in the global insurance distribution market, and we are confident in the company’s potential for continued growth.”

LLC are serving as financial advisors to Ardonagh, while Paul, Weiss, Rifkind, Wharton & Garrison LLP is acting as its legal advisor.
