Great Lakes Dredge & Dock Corporation, the largest U.S. dredging services provider, outlines its single-segment dredging business and growing offshore energy operations. Dredging generated 97% of 2025 revenue, led by deep port capital work and coastal protection, with the company holding a three-year average U.S. bid market share of 29%.
The company has agreed to be acquired by Saltchuk Resources via a tender offer at $17.00 per share, followed by a merger that will make Great Lakes a wholly owned subsidiary and lead to delisting from Nasdaq, subject to a majority tender and antitrust clearance. It is also investing in offshore energy through the Acadia, a Jones Act subsea rock installation vessel launched in July 2025 and expected to be operational in the first half of 2026, backed by U.S. wind contracts and initial European offshore wind awards.
Great Lakes Dredge & Dock Corporation reported strong fourth quarter and full year 2025 results and highlighted a pending acquisition by Saltchuk Resources, Inc. Full year revenue reached $888.3 million and net income was $73.5 million, both higher than 2024. Adjusted EBITDA rose to a record $171.3 million, reflecting better project performance and higher capital, coastal protection, and offshore energy revenues.
Total backlog was $888.1 million as of December 31, 2025, including $124.8 million in offshore energy backlog. The company also signed two new international offshore energy contracts with a major offshore wind developer that will keep the vessel Acadia working in Europe for most of 2027. Great Lakes previously announced a definitive agreement for Saltchuk to acquire the company, with closing expected in Q2 2026 subject to customary conditions.
Great Lakes Dredge & Dock Corporation reports that, as previously announced, it entered into a definitive agreement on February 10, 2026 to be acquired by Saltchuk Resources, Inc. at an aggregate equity value of approximately $1.2 billion and a total transaction value of $1.5 billion.
Because of this pending transaction, the company will not hold its previously scheduled earnings call on February 17, 2026. It still expects to release financial results for the three and twelve months ended December 31, 2025 in connection with filing its Annual Report for that period.
