The Ardonagh Group, the London-based independent insurance distribution platform, announced the completion of a $2.5 billion equity investment led by funds managed by Stone Point Capital LLC, the US-based private equity firm.

The investment, which valued the group at $14 billion, saw strong demand from co-investors connected to Stone Point, as well as to Madison Dearborn Partners (MDP) and HPS Investment Partners (HPS).

Stone Point is now a significant shareholder in Ardonagh, alongside MDP, HPS, and other large global institutions, including a wholly owned subsidiary of the Abu Dhabi Investment Authority (ADIA).

With support from this diversified group of high-quality investors, Ardonagh said it is well placed to capture numerous growth opportunities in the global P/C insurance market through its platform of businesses, which each have a strong regional in-market presence.

Ardonagh was founded in 2017 through the merger of several UK insurance businesses which created a diversified group that provides wholesale, retail and specialist insurance solutions, Ardonagh has since transformed into a top-20 global broking group placing $18 billion of premiums and operating across the entire insurance distribution value chain, the broker said.

Completion of the investment continues Ardonagh’s growth momentum following a number of deals made in 2024. The group completed the sale of its personal lines business to Markerstudy in June 2024 as well as the A$2.3 billion take-private of Australia’s PSC Insurance Group in October, one of 68 acquisitions across multiple geographies completed in the year.

Most recently, the group’s capital structure was simplified with a successful refinancing in February 2025, and in March 2025, it launched Ardonagh Intelligence, marking a new phase in its journey to harness the best of machine learning and data enrichment across its businesses to extend the benefits the group can deliver to the millions of clients it serves.

“Stone Point’s investment and the success of the co-investment process stand together as a resounding endorsement of Ardonagh. Amid a backdrop of global economic uncertainty, our unique proposition, track record and global platform attracted world-class investors who share our vision,” commented David Ross, CEO of The Ardonagh Group.

“We are proud to welcome Stone Point into the fold in this next chapter alongside long-term partners whose support has been invaluable in our journey to becoming a $14 billion company,” Ross added. “With such strong financial backing, Ardonagh has unparalleled empowerment to capitalise on future growth opportunities and deliver value to our clients, investors and people.”

“We are excited to partner with Ardonagh, as well as with MDP, HPS and ADIA. Ardonagh has distinguished itself as a leading platform in the global insurance distribution industry, and we believe that the company is well-positioned for continued growth,” commented Jim Carey, co-CEO of Stone Point.

Fenchurch Advisory Partners, Goldman Sachs Investment Banking & Co. LLC and Morgan Stanley & Co. LLC are acting as financial advisors to Ardonagh. Paul, Weiss, Rifkind, Wharton & Garrison LLP is acting as legal advisor to Ardonagh, while Debevoise & Plimpton LLP is acting as legal advisor to Stone Point.
