In June 2024, RSK announced a preferred equity investment agreement from a consortium led by Searchlight Capital Partners and Ares Management Corporation funds totaling £500 million, with the investment completing in September 2024 at £520 million after additional capital from existing shareholder BGF (£20 million).
