Enstar Group Limited's ownership journey saw a significant shift from its public listing to its recent privatization. Initially known as Castlewood Limited, the company rebranded as Enstar Group after a 2007 merger and subsequent Nasdaq IPO, which facilitated its expansion. This public status allowed for broad ownership, with institutional investors forming the vast majority of its shareholder base.

Before its acquisition, Enstar Group's ownership was predominantly held by institutional investors, representing nearly 94% of its shares. Among these, investment funds managed by Stone Point Capital LLC held a notable 9.5% stake as of December 31, 2024. This concentration highlights the significant influence of large financial institutions in the company's shareholder structure.
