Great Lakes Dredge & Dock Business Summary

Great Lakes Dredge & Dock Corporation (GLDD) is the largest provider of dredging services in the United States, operating a specialized fleet of approximately 200 vessels to maintain and expand maritime infrastructure. The company generates revenue through high-value government and private contracts across four primary segments: Capital Dredging (port deepening and expansion), Coastal Protection (beach nourishment and storm mitigation), Maintenance Dredging (navigational waterway preservation), and its burgeoning Offshore Energy division, which focuses on subsea rock installation for offshore wind foundations. As of March 2026, GLDD is transitioning toward a private ownership model following a definitive $1.2 billion acquisition agreement with Saltchuk Resources, which valued the company at $17.00 per share. In the competitive landscape, GLDD maintains a dominant market share relative to peers such as Manson Construction, Orion Group Holdings, and MYR Group, leveraging its pioneering Jones Act-compliant vessel, the Acadia, to secure a first-mover advantage in the domestic offshore wind sector. Originally founded in 1890 as the Lydon & Drews Partnership by William A. Lydon and Fred C. Drews, the company is currently led by President and CEO Lasse Petterson, a veteran executive with a pedigree from Chicago Bridge & Iron (CB&I) and Aker Maritime. The senior leadership team includes SVP and CFO Scott Kornblau, formerly of Diamond Offshore Drilling, and VP and Chief Technology Officer Trond Ellefsen, who oversees the firm's digital transformation and cybersecurity initiatives. Strategic market expansion into offshore energy is directed by SVP Eleni Beyko, while the board is chaired by Lawrence R. Dickerson. Prior to the pending Saltchuk merger, the company maintained a strong institutional investor base led by BlackRock, Dimensional Fund Advisors, and Vanguard, reflecting its critical role in U.S. national maritime security and infrastructure.
