Antin Infrastructure Buys Vigor Marine from Lone Star Funds

Antin Infrastructure Partners has finalized its acquisition of Vigor Marine Group, a significant player in the U.S. maritime services sector, from Lone Star Funds. This strategic move positions Antin to capitalize on the robust demand for maintenance, repair, and overhaul (MRO) services within the naval, defense, and commercial shipping industries.

Vigor Marine Group, headquartered in Portland, Oregon, boasts a substantial operational footprint with shipyard and fabrication facilities across five key locations. The company employs approximately 2,700 individuals, contributing significantly to the industrial workforce in the Pacific Northwest, Virginia, and California. Its comprehensive service portfolio caters to a diverse clientele, including critical government entities like the U.S. Navy, U.S. Army, Military Sealift Command, and the U.S. Coast Guard, alongside major players in the ferry, cruise, and commercial fishing sectors.

Under Lone Star Funds' stewardship, Vigor Marine underwent a period of strategic expansion and capability enhancement. The private equity firm collaborated with Vigor's management to invest in facility upgrades and technological advancements, streamlining operations under a unified brand. This focus on operational integration has solidified Vigor Marine's position as a leading provider capable of addressing mission-critical needs for its extensive customer base.

The divestiture by Lone Star Funds, which advised funds including Lone Star Fund XI, L.P., marks a successful exit following its investment strategy. Lone Star, a veteran investment firm with over three decades of experience in complex situations, has a proven track record of value creation. Since its inception in 1995, the firm has managed 26 private equity funds, amassing approximately $96 billion in capital commitments, underscoring its significant market presence and investment capacity.

This transaction aligns with broader trends in the infrastructure and industrial services sectors, where specialized MRO providers are increasingly sought after due to aging fleets and heightened geopolitical security concerns. The maritime MRO market, estimated to be worth billions globally, is experiencing steady growth driven by increased shipping volumes and defense spending. Antin Infrastructure Partners, known for its focus on essential infrastructure assets, is well-positioned to leverage Vigor Marine's established market position and expand its service offerings.

Donald Quintin, Chief Executive Officer of Lone Star, commented on the successful conclusion of the partnership, highlighting it as a significant milestone and a testament to Lone Star's strategy of investing in and nurturing market-leading businesses. He expressed confidence in Vigor Marine's continued growth trajectory under its new ownership.
