What Orion Marine Group does
Orion Marine Group, legally Orion Group Holdings, Inc. (NYSE: ORN), is a Houston-headquartered heavy civil marine and concrete construction contractor organized into three integrated divisions: Orion Marine (marine construction, diving, and marine services with a claimed 100-year legacy), Orion Concrete (concrete construction including a dedicated data center vertical with 40+ years of expertise concentrated in Texas and Florida), and Orion Engineering & Consulting (marine and civil engineering, planning, design, permitting, and Engineer of Record services delivered via Schneider Engineering & Consulting). The company pursues large infrastructure projects through a direct enterprise sales motion, winning work via competitive bidding on federal/state contracts (U.S. Army Corps of Engineers, U.S. Navy) and direct negotiation with private industrial and energy customers (e.g., Vigor Shipyard, Golden Pass LNG). Its go-to-market is project-based, with multi-year contract durations and pricing driven by scope, complexity, materials, labor, equipment, and timeline rather than standardized tiers.
The company monetizes through three one-time/license-style revenue streams: marine construction services (dredging, shoreline protection, habitat restoration, pier reconstruction), concrete construction services, and professional engineering & consulting services. In 2026 Orion executed a ~$60 million acquisition of J.E. McAmis, Inc. and JEM Marine Leasing LLC to broaden marine construction capability, secured an $86.3 million U.S. Army Corps of Engineers shoreline protection contract, and refinanced into a new $120 million Senior Credit Facility with UMB Bank (replacing the prior $88 million facility). Operations span the contiguous United States, Alaska, Hawaii, Canada, and the Caribbean, with a stated portfolio of over 5,000 completed projects.
