SEATTLE and HOUSTON, April 01, 2026 (GLOBE NEWSWIRE) -- Saltchuk Resources, Inc. (“Saltchuk”) today welcomed Great Lakes Dredge & Dock Corporation ( GLDD ) (“Great Lakes”) as its newest wholly owned subsidiary. The transaction closed this morning for a purchase price of $17.00 per share in cash, and an enterprise value of approximately $1.5 billion.  

“We're proud to welcome Great Lakes to the Saltchuk family of companies,” said Saltchuk Chairman Mark Tabbutt. “With Great Lakes, we have grown to nearly 10,000 team members united by a shared commitment: delivering safe, responsible, and reliable service to the communities we serve. We look forward to supporting Great Lakes’ reinvestment and growth ambitions for generations to come.”

Great Lakes joins Saltchuk as a stand-alone business unit, and it will continue to operate independently under its experienced leadership. The acquisition diversifies  Saltchuk’s portfolio, adding dredging services to complement more than 30 other U.S. freight transportation, marine services, and energy distribution companies.

“Joining Saltchuk’s family of companies is a proud moment for us, as it is an organization that shares our deeply rooted culture and unwavering commitment to safety, to the communities we serve, our valued customers, and our dedicated employees. This partnership represents a natural alignment of values and vision, providing a strong foundation for continued collaboration and success,” said Lasse Petterson, Great Lakes’s President and Chief Executive Officer. “As we look ahead, we remain focused on executing our long-term growth strategy with discipline and purpose. At the same time, we are committed to maintaining and enhancing our leadership position in U.S. dredging, the global offshore energy sector, and continuing to deliver excellence and innovation across all aspects of our business.”
