Will Great Lakes' $1B Backlog Keep Margins Strong Through 2026?

Great Lakes Dredge & Dock (GLDD) is experiencing strong growth, with its dredging backlog reaching $1 billion as of March 31, 2025, driven by capital and coastal protection projects, which comprise 95% of the backlog. The company's gross margin expanded by 570 basis points to 28.6% year-over-year in Q1 2025, supported by government-funded projects and an ongoing fleet modernization program with over $500 million invested, leading to a 52.8% surge in its stock price over the past three months and upward revisions in 2025 and 2026 EPS estimates.

Analysis

Great Lakes Dredge & Dock Corporation (GLDD) exhibits a strong operational and financial outlook, underpinned by a substantial dredging backlog which reached $1 billion as of March 31, 2025, an increase from $879.4 million in the prior year's first quarter. Notably, 95% of this backlog consists of capital and coastal protection projects, areas where GLDD holds a competitive advantage and which benefit from government funding, thereby reducing payment failure risks and enhancing revenue visibility. This operational strength translated into a significant gross margin expansion of 570 basis points year-over-year to 28.6% in the first quarter of 2025. Supporting future growth is GLDD's ongoing fleet modernization program, with over $500 million invested and an additional $140-$160 million planned for 2025, crucial for executing large-scale projects. The market has responded positively, with GLDD's shares soaring 52.8% in the past three months, and earnings estimates for 2025 and 2026 have been revised upwards by 34.8% to 93 cents per share and 11.8% to 95 cents per share, respectively. Despite the stock's rally, its forward 12-month P/E ratio of 12.52X indicates a potentially favorable valuation compared to industry peers. The broader heavy construction sector, including competitors like Orion Group Holdings (ORN) with its $839.7 million backlog and Quanta Services (PWR) with a $35.25 billion backlog, similarly benefits from strong public infrastructure funding, signaling a positive industry backdrop.

Key Decisions for Investors

• Considering GLDD's robust $1 billion backlog heavily weighted towards capital and coastal protection, a Q1 2025 gross margin expansion of 570 basis points to 28.6%, upwardly revised EPS estimates for 2025 and 2026, and a Zacks Rank #1 (Strong Buy), investors may find the stock an attractive opportunity within the heavy construction sector.
• Key factors for ongoing assessment include the successful execution of its fleet modernization program, the continued strength of government funding for infrastructure and coastal projects, and the company's ability to maintain margin strength amidst macro risks.
• While the stock has appreciated significantly by 52.8% in the past three months, its forward P/E ratio of 12.52X suggests valuation may still be reasonable; however, investors should monitor for sustained operational performance to support the current valuation and be cognizant of the capital expenditure for the new build program.
