Risk factors and legal proceedings
The risks Great Lakes Dredge & Dock CORP names in Item 1A of its 10-K filed Feb 23, 2026: 56 risks under these headings, as written.4
- Risks Related to the Pending Transaction
- The Transaction is subject to a number of conditions, which may not be satisfied in a timely manner or at all.
- Uncertainties associated with the Transaction could adversely affect our business, results of operations, financial condition and stock price.
- Failure to complete the Transaction within the expected timeframe, or at all, could adversely affect our business and stock price.
- The Merger Agreement contains provisions that limit our ability to pursue alternatives to the Transaction and may discourage other third parties from offering a favorable alternative transaction proposal.
- We are subject to certain restrictions on the conduct of our business under the terms of the Merger Agreement.
- Lawsuits may be filed against us and the members of our board of directors arising out of the proposed Transaction, which may delay or prevent the proposed Transaction or otherwise negatively affect our business and operations.
- Our stockholders will not benefit from future growth opportunities as stockholders of the Company if the Transaction is completed.
- Risks Related to our Business
- A reduction in government funding for dredging or other contracts, or government cancellation of such contracts, or the inability of the Corps to let bids to market could materially adversely affect our business operations, revenues and profits.
- Our inability to qualify as an eligible bidder for government contracts or to compete successfully with other qualified bidders for certain contracts could materially adversely affect our business operations, revenues and profits.
- Our business and operating results could be adversely affected by the political environment and governmental fiscal and monetary policies.
The other 46 risks
- Our significant number of fixed-price contracts subjects us to risks associated with cost over-runs, operating cost inflation and potential claims for liquidated damages. If we are unable to accurately estimate our project costs our profitability could suffer.
- Our quarterly and annual operating results may vary significantly based on the timing of contract awards and performance.
- If we fail to comply with government contracting regulations, we could be subject to significant potential liabilities and loss of revenue.
- Project delays related to the increasingly negative impacts of climate change or other unusual, non-historical weather patterns have and may continue to impact our ability to perform projects on time and on budget and therefore could materially adversely affect our business operations, revenues and profits.
- Costs necessary to operate and maintain our vessels tend to increase with the age of the vessel, and costs of such maintenance, as well as costs associated with new build programs, may also increase due to changes in applicable regulations or standards, which could decrease our profits.
- Equipment or mechanical failures could result in increased costs, project delays and reduced revenues.
- A pandemic, epidemic or outbreak of an infectious disease affecting our markets or impacting our facilities or suppliers could adversely impact our business.
- Disruptions to our supply chain affecting our markets or impacting our facilities or suppliers could prohibit procurement of materials necessary for maintenance of our existing vessels and new vessel build materials and adversely impact our business.
- Environmental regulations could force us to incur capital and operational costs.
- We may be affected by market or regulatory responses to climate change.
- Penalties for late completion of contracts could reduce our profits.
- Force majeure events could negatively impact our business, operations, revenues, cash flows and profits.
- The amount of our estimated backlog may change and may not be indicative of future revenues.
- Loss of a single customer contract could significantly decrease revenue.
- Inability to obtain secure financing or financing on favorable terms for any future new vessels could negatively impact our business, financial position and/or results of operations.
- Inability to secure contracts to utilize our new offshore energy vessel could adversely impact our business strategy and have a material adverse effect on our operating results, cash flows or financial condition.
- Unforeseen delays and cost overruns could postpone delivery of or halt plans to build new vessels and, as a result, negatively impact our business strategy.
- Our business would be adversely affected if we failed to comply with Jones Act provisions on coastwise trade, or if those provisions were modified, repealed or interpreted differently.
- If we fail to comply with anti-discrimination laws, including those pertaining to diversity, equity and inclusion programs, we could be subject to legal action and reputational risk.
- Our operating costs depend significantly on the price of petroleum-based products, and price increases could adversely affect our profits.
- Our investing and operating costs depend significantly on the prices of new build and general maintenance and repair materials, and price increases due to high nationwide inflation could adversely affect our profits.
- An inability to obtain bonding or letters of credit would limit our ability to obtain future contracts, which could, along with any draws on existing arrangements, adversely affect our business, operating results, cash flows and financial condition.
- Acquisitions involve integration, consolidation and strategic risks and may involve significant transaction expenses and unexpected liabilities, which could adversely affect our business and results of operations.
- Divestitures and discontinued operations could negatively impact our business, and any retained liabilities could adversely affect our financial results.
- We could face liabilities and/or damage to our reputation as a result of legal and regulatory proceedings.
- Liabilities for the obligations of our joint ventures and similar arrangements and subcontractors could materially decrease our profitability and liquidity.
- New tariffs have increased our costs and could adversely affect our business operations, revenues and profits.
- Our business could suffer in the event of a work stoppage by our unionized labor force.
- Liabilities imposed by federal laws for job-related claims by seagoing employees could increase our costs and reduce our profitability.
- The significant operating risks and hazards inherent in the operation of our business could result in personal or property damage, which could result in losses or liabilities to us.
- Risks Related to our Financing
- We have substantial indebtedness, which makes us more vulnerable to adverse economic and competitive conditions.
- Terms and covenants in our financing arrangements limit, and other future financing agreements may limit, our ability to operate our business.
- Adverse capital and credit market conditions may affect our ability to access capital and meet liquidity needs.
- Regulatory requirements for derivative transactions could adversely impact our ability to hedge interest rate, currency or commodity risks.
- We may be subject to foreign exchange risks, which could result in large cash losses.
- Our investments in, and extensions of payment terms for, privately financed projects could result in significant losses.
- Risks Related to our Stock
- Our common stock is subject to restrictions on foreign ownership.
- Delaware law and our charter documents may impede or discourage a takeover that our stockholders may consider favorable.
- Our stockholders may not receive dividends because of restrictions in our debt agreements or Delaware law.

- Our current insurance coverage may not be adequate, and we may not be able to obtain insurance at acceptable rates, or at all.
- If we are unable to find, attract and retain skilled labor and key personnel, including governance personnel, our business, results of operations, cash flows or financial condition could be materially and adversely affected.
