HOUSTON, Nov. 25, 2025 (GLOBE NEWSWIRE) -- Great Lakes Dredge & Dock Corporation ("Great Lakes" or the “Company”) (NASDAQ: GLDD), the largest provider of dredging services in the United States, announced today that the Company’s issuer credit rating has been upgraded to “B” from “B-” by S&P Global Ratings (“S&P”) with the outlook remaining stable.

S&P based its ratings upgrade in part due to the Company’s improved revenues, earnings and expanding margins along with decreasing capital expenditures that will support healthy free cash flow generation over the next couple of years. The stable outlook reflects S&P’s expectation that Great Lakes will continue to grow revenue and expand margins through 2026 and their expectation that the Company will generate increasingly positive free cash flow as the new build program comes to an end.

Great Lakes’ Senior Vice President and Chief Financial Officer, Scott Kornblau, commented, “The recent credit rating upgrade from S&P validates the strong progress we’ve achieved this year in strengthening our balance sheet, driving positive cash flows, and elevating overall performance. This milestone not only affirms our strategy but also sets the stage for even greater growth and long-term success.”
