Antin Infrastructure Partners Acquires Vigor Marine Group

Antin Infrastructure Partners, a private equity firm focused on infrastructure, has announced its acquisition of Vigor Marine Group from Lone Star Funds. Vigor, based in Portland, Oregon, offers maintenance and repair services to naval, defense, and commercial maritime sectors in the U.S. This marks Antin's seventh investment from its $11.8 billion Flagship Fund V, emphasizing its commitment to U.S. infrastructure.

The acquisition will enable expansion at Vigor's facilities across five U.S. locations. Antin aims to enhance innovation and workforce development. Vigor, generating nearly $1 billion in revenue in 2024, employs about 2,700 staff. CEO Francesco Valente and the current management team will remain.

This transaction strengthens Antin's focus on essential infrastructure investments in North America and Europe. It awaits regulatory approval and is set to conclude in 2026.
