## Overview

Great Lakes Dredge & Dock Corporation is a U.S.-based marine construction contractor focused on dredging, coastal protection, and related waterway infrastructure work. It also has a growing offshore energy activity, including subsea rock installation and other marine services tied to offshore wind, cable, and energy projects.

## Products & services

• Capital dredging for ports, channels, LNG terminals and land reclamation
• Maintenance dredging for navigation channels and waterways
• Coastal protection and beach nourishment / shoreline restoration
• Offshore energy services, including subsea rock installation
• Marine construction support for breakwaters, jetties, canals and pipelines

- **Domestic capital dredging** (42%) — Deepening ports and channels, LNG access work, land reclamation and related marine construction.
- **Coastal protection** (27%) — Beach nourishment, shoreline stabilization and coastal resiliency projects for public agencies.
- **Maintenance dredging** (13%) — Recurring dredging to keep navigation channels, harbors and waterways open and usable.
- **Offshore energy** (3%) — Marine services for offshore wind, cable and oil and gas projects, including rock installation.
- **International dredging and marine work** (15%) — Selective overseas dredging and marine construction projects where the fleet is competitive.

- Maintenance dredging for navigation channels and inland waterways
- Coastal protection, beach nourishment and shoreline restoration
- Offshore energy services, including subsea rock installation
- Marine construction for breakwaters, jetties, canals and pipelines

## Customers

The company sells mainly to public-sector customers, especially the U.S. Army Corps of Engineers, plus the U.S. Coast Guard, U.S. Navy, and state and local governments. It also serves private and quasi-private customers such as utilities, offshore wind developers, cable installers, oil and gas companies, and other marine infrastructure owners. Most work is awarded through competitive bidding, so customers buy when they need specialized equipment, regulatory certifications, and proven execution on complex marine jobs.

- **Federal government agencies** (primary) — Buys navigation, flood control, coastal resiliency and facility-related dredging; this is the core customer base and largest source of demand.
- **State and local governments** (primary) — Buys coastal protection, beach nourishment and restoration projects funded through public budgets and disaster relief programs.
- **Private marine infrastructure owners** (secondary) — Buys port, terminal, pipeline, cable and industrial marine work where specialized dredging and marine construction are needed.
- **Offshore energy developers and contractors** (emerging) — Buys subsea rock installation and related marine services for offshore wind, cables and energy projects.

- U.S. Army Corps of Engineers for navigation and flood control projects
- Federal agencies such as the Coast Guard and Navy for facility work
- State and local governments for coastal protection and restoration
- Utilities and offshore wind developers for marine energy infrastructure
- Oil and gas and cable installers for trenching and subsea support

## Geography

Great Lakes is primarily a U.S. coastal and inland waterways business, with operations on the East Coast, Gulf Coast and throughout inland rivers and lakes. The company also performs selective international projects, but domestic work remains the main revenue base and the most important bidding market. Its fleet mobility matters because equipment can be redeployed across regions as project demand shifts.

- Core operations on the East Coast and Gulf Coast
- Work also extends across inland U.S. rivers and lakes
- Domestic bid market is the main revenue engine
- Selective international projects supplement the U.S. base
- Fleet mobility lets equipment move to higher-demand regions

## Strategy

The company is focused on defending its core U.S. dredging franchise while using its fleet and certifications to win the most complex, high-barrier projects. A second priority is expanding offshore energy work, where it can leverage marine construction capabilities into subsea rock installation and related services. It also continues to invest in fleet upgrades, maintenance reliability and regulatory certifications that support bid eligibility and pricing power.

- **Win complex domestic dredging and coastal protection work** (short-term) — These projects fit the fleet and face fewer qualified competitors, supporting utilization and margins.
- **Grow offshore energy capabilities** (medium-term) — Offshore wind and subsea infrastructure broaden the addressable market beyond traditional dredging.
- **Maintain fleet certification and reliability** (medium-term) — U.S. Coast Guard and ABS certifications are required for many exposed-water projects and support competitive bidding.

- Protect share in the U.S. dredging bid market
- Target complex jobs where certified equipment is a barrier to entry
- Expand offshore energy services beyond traditional dredging
- Maintain and upgrade the fleet to improve reliability and efficiency
- Preserve bid eligibility through safety and regulatory compliance

## Risks

The business is exposed to project concentration, public funding cycles and competitive bidding, so delays or funding changes can quickly affect utilization. Operations also carry heavy industrial and environmental risk because accidents, weather, geological surprises and equipment downtime can disrupt projects and create liability. Offshore energy expansion adds execution risk, while supply chain, dry-dock scheduling and regulatory compliance can affect cost and timing.

- **Dependence on federal and public funding** [high] — A large share of revenue comes from the Corps and other government customers, so budget shifts or continuing resolutions can delay projects.
- **Competitive bid pricing pressure** [high] — Most contracts are awarded to the lowest qualified bidder, which can compress margins when competition intensifies.
- **Marine operating hazards** [high] — Dredging involves collisions, cave-ins, flooding, environmental incidents and unexpected geology that can cause losses and claims.
- **Supply chain and dry-dock disruption** [medium] — Maintenance, repairs and new vessel work depend on shipyards and suppliers, which can delay availability and raise costs.
- **Offshore energy market execution** [medium] — The company is expanding into a newer end market where demand timing, customer mix and competition are less proven than core dredging.

- Heavy dependence on federal and public-sector project funding
- Competitive bidding can pressure pricing and reduce margins
- Marine construction hazards can cause delays, damage and liability
- Supply chain and shipyard disruptions can delay maintenance and builds
- Offshore energy expansion adds execution and market-development risk

## Accounting

Revenue is driven by long-duration, project-based contracts, so timing of work performed and project mix can move quarterly results materially. Investors should watch estimates around contract costs, claims, dry-dock and maintenance expense, and any impairment testing for vessels or goodwill if utilization weakens. Seasonality and project timing also matter because revenue can shift between quarters as large dredging and coastal projects start, pause or complete.

- **Over-time contract revenue recognition** — Quarterly revenue and gross profit can shift with project progress and revisions to cost estimates.
- **Project cost estimates and claims** — Can materially affect gross margin and contract profitability.
- **Dry-dock and maintenance timing** — Quarterly comparability and vessel availability can be distorted.
- **Impairment of vessels and goodwill** — Could create non-cash charges if market conditions weaken.

- Project-based revenue recognition affects timing of reported sales
- Cost estimates on long contracts can change gross margin materially
- Dry-dock and maintenance timing can create quarter-to-quarter volatility
- Vessel and goodwill impairment risk matters if fleet utilization weakens
- Claims, contingencies and environmental liabilities can affect earnings
