RiverStone Taps Enstar’s Brockman as Group CEO, Succeeding Tanzer
RiverStone International Holdings, the UK-based acquirer and reinsurer of legacy and discontinued insurance business, announced the appointment of Paul Brockman as group chief executive officer to succeed Luke Tanzer who is retiring later this year.
RiverStone also announced the appointment of Andrew Creed as group president in addition to his role as group chief financial officer.
Brockman will join RiverStone from the Enstar Group where he has most recently served as group chief commercial officer. He has also previously served within Enstar in a number of roles including group chief operating officer, group chief claims officer and CEO of both Enstar’s US and European businesses.
Brockman has spent more than 30 years in the legacy sector and has significant experience in the US, London, Bermuda and international markets. He is expected to join in January 2026, and his appointment is subject to customary regulatory approvals.
Creed will be promoted to the position of group president and will continue as group chief financial officer. RiverStone said Creed has been fundamental to the company’s growth and success for more than 12 years as finance director, group chief financial officer and chief executive officer of RiverStone’s UK and Lloyd’s businesses. He has extensive expertise across all aspects of the group which he will bring to his new role.
A statement from the board of Riverstone said: “The board would like to thank Luke for his enormous contribution as group CEO of RiverStone over the past 16 years from its time as part of the Fairfax Group and then as an independent company since the change in ownership to funds managed by CVC in 2021. During his leadership the group has grown from a UK-focused business into a global leader in non-life run-off insurance, while maintaining the strength of its culture and focus on relationships with all stakeholders.”
Since 2010 RiverStone has completed 47 transactions acquiring US$17.7 billion in gross liabilities. In 2024 the group reported $300 million in adjusted profit before tax with a 19.1% return on opening adjusted tangible book value.
