Third Coast Acquires Interest in Deepwater Perdido Platform from ArcLight

HOUSTON, July 5, 2023 /PRNewswire/ -- Third Coast Super Holdings, LLC ("Third Coast") is pleased to announce that a subsidiary has successfully acquired an indirect 26.5% non-operated interest in the Perdido Regional Host ("Perdido") from a subsidiary of ArcLight Energy Partners Fund VI, L.P., a private equity fund managed by ArcLight Capital Partners, LLC ("ArcLight"). Perdido is a spar platform located in water depths of approximately 8,000 feet in Alaminos Canyon in the western Gulf of Mexico ("GOM") approximately 220 miles south of Galveston, TX and 6 miles from the US/Mexico maritime border.

"We are extremely excited to acquire this world class asset from ArcLight.

"This acquisition continues our growth strategy which is focused on deep water GOM assets while also providing diversification of our portfolio into the western GOM." "Since our acquisition of the Perdido interest in 2018, we've been extremely pleased with the asset and the critical role it plays in the western GOM," said Joe Alves, a Managing Direct at ArcLight. "As a leading infrastructure operator in the Gulf, we see Third Coast is the natural owner of the Perdido interests, complementing its interests in the Delta House and King's Quay FPS platforms. We are excited for the opportunities this transaction unlocks for Third Coast."
