KEY TAKEAWAYS: Solaris Energy Infrastructure acquired Slaughter-based Omega Foundation Services in a cash, debt and stock transaction. Omega gives Solaris additional construction capabilities for data centers, power plants and other infrastructure projects. Turn Services acquired St. John Flee ting, adding a Mississippi River location near Reserve with capacity for up to 300 barges. Tallvine Partners acquired substantially all assets of Galliano-based Crosby Enterprises following the marine company’s Chapter 11 proceedings.   Houston-based Solaris Energy Infrastructure (SEI) has strengthened its power infrastructure capabilities with the acquisition in September of Slaughter, Louisiana-based Omega Foundation Services.  The deal is expected to broaden SEI’s full-cycle power solutions while creating additional opportunities across several growing Louisiana end markets. Founded in 2020, Omega is a specialized engineering, procurement and construction company with expertise in deep foundations, heavy civil construction and hydro excavation. Its work extends from data center and power plant sites to industrial and utility infrastructure, giving Solaris construction capabilities at the front end of the projects it already serves with power generation, distribution, installation and ongoing support. Publicly traded Solaris acquired Omega for approximately $101 million in net cash consideration, $28 million in assumed debt and leases, and the issuance of approximately 3.6 million of its Class A shares.  Solaris expects the acquisition to be immediately accretive to earnings and free cash flow per share. Chairman and co-CEO Bill Zartler and co-CEO Amanda Brock described Omega as “another key piece of the power value chain.” They said the combination should improve SEI’s control over construction costs and schedules while opening opportunities in data centers, LNG, industrial and government projects. The two companies had worked together at multiple locations for two years before the transaction, giving Solaris direct experience with Omega’s crews and execution. Omega ranked No. 145 on the 2026 Inc. 5000 after posting 2,152% growth over three years, according to Inc. Two Lower Mississippi River deals expand networks Convent, Louisiana-based Turn Services completed its acquisition of St. John Fleeting and its affiliated companies on Sept. 14, adding a fleeting location near Reserve at approximately mile marker 140 on the Mississippi River. The location can accommodate up to 300 barges, including dry, liquid, pressure, deck and oversized barges. Financial terms were not disclosed. St. John Fleeting had served river customers for 50 years, including fleeting, transportation, stevedoring, barge repair and dock transfers. Turn, founded in 1990, offers barge cleaning, repair and vessel operations from Baton Rouge to the mouth of the Mississippi and towing services all along the Gulf Intracoastal Waterway. The acquired fleet adds space in the Port of South Louisiana jurisdiction, where access to a well-placed berth can help customers manage vessel movements and cargo handling. The companies announced an agreement in November 2025 before closing the deal this September. Turn President Todd Fuller said the addition “strengthens our ability to serve customers at a critical location on the Lower Mississippi River.” Turn plans to integrate the site into its existing marine services network while carrying forward St. John’s longstanding operation. Farther down the coast, Miami-based Tallvine Partners announced on Sept. 16 that its North America marine infrastructure platform had acquired substantially all assets of Galliano-based Crosby Enterprises and certain affiliates. The sale followed Crosby’s Chapter 11 proceedings and a court-approved process authorized by the U.S. Bankruptcy Court for the Eastern District of Louisiana on Sept. 3. Crosby continued operating during the proceedings, and Tallvine said its crews, vessels and shore facilities would continue serving customers without interruption. The purchase price was not disclosed. Founded in 1977, Crosby operates more than 150 tugboats, dredges and support vessels, along with shipyard and berth facilities in Houma and Port Fourchon. Its services span offshore and inland towing, dredging, rock placement, marine construction support and shipyard work for customers that depend on navigable waterways, ports and energy infrastructure. The acquisition is Tallvine’s third for its marine platform, following Donjon Marine in September 2025 and Lind Marine in May 2026. Mike Ellis, former CEO  of American Commercial Barge Line, is joining as an operating adviser, while Thoroughbred Investment Partners remains the platform’s industrial partner. Tallvine CEO Thomas Lefebvre said the firm is committed to investing in Crosby’s “people, fleet and infrastructure” as it builds out its Gulf Coast presence. G.F.
