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”).
