Enstar Group

Enstar Group Limited describes itself as a trusted global re/insurance group and the leading global provider of retrospective solutions, with specialist underwriting capabilities, helping clients manage complex risk, unlock capital and create the financial freedom to grow. Its history dates back to 1993 in Bermuda with the launch of Castlewood Limited, which focused on the overlooked run-off space; in 2007 Castlewood merged with Enstar Group, adopting its name and listing on Nasdaq. In July 2025, Enstar was acquired by a consortium of investors led by Sixth Street and became a privately held company. The company reports $19.9bn in assets and $12.3bn in insurance liabilities as at 30 June 2026, with 130+ transactions executed and financial strength ratings of 'A' from AM Best and S&P through its flagship reinsurer Cavello Bay.

Enstar's history dates back to 1993, when its story began in Bermuda with the launch of Castlewood Limited. Recognising untapped potential in the overlooked run-off space, its founders set out to support global re/insurers by taking on their discontinued operations. Castlewood built a reputation for disciplined, strategic deal-making, helping to shape the emerging run-off market with innovative transactions that enabled counterparties to clean up legacy exposures to asbestos and other catastrophe losses; early transactions included Wackenhut, Allied Domecq and Foster Wheeler. By the early 2000s, new investors JC Flowers and Stone Point Capital enabled Castlewood to expand its reach, leading to larger transactions including River Thames Insurance, Turegum and Gordian. In 2007, Castlewood merged with Enstar Group, adopting its name and listing on Nasdaq to access the public capital markets. By 2013, Enstar had become the world's largest standalone legacy reinsurance consolidator. In July 2025, Enstar was acquired by a consortium of investors led by global investment firm Sixth Street and became a privately held company.
