STAMFORD, Conn. and HOUSTON, June 2, 2025 /PRNewswire/ -- A newly formed partnership between First Reserve, a leading private equity firm investing across energy, utility, and industrial markets, and funds managed by affiliates of Fortress Investment Group ("Fortress"), a leading global investment manager, today announced an agreement to acquire a majority stake in Island Energy Services, LLC ("IES" or the "Company"), one of Hawaii's leading integrated fuel logistics and infrastructure providers. The Company's current owner, an affiliate of One Rock Capital Partners, LLC ("One Rock"), will remain an investor in the Company. Financial terms of the transaction, which is expected to close in the third quarter, were not disclosed.
