Brockman’s tenure will begin in January 2026, subject to regulatory approvals, the company said.
During Tanzer’s 16 years tenure as group CEO, RiverStone expanded from a UK-focused business to a global participant in non-life run-off insurance.
Tanzer said: “It has been a privilege to be part of RiverStone’s incredible journey over the past 27 years and to have led the company for the past 16 years.
“I would like to extend a very warm welcome to Paul who is an inspired choice as our next CEO and also my deepest congratulations to Andy who has been a brilliant partner over the last 12 years. Together I’m sure Paul and Andy and the rest of the team will take the company forward to new heights of growth and success in the years to come.”
