In addition, the Company has a long history of performing significant international projects. Despite the challenges we faced related to the COVID-19 pandemic, the domestic dredging market remained strong in 2021 with continued focus around port deepening projects on the East and Gulf Coasts and coastal protection projects, which include renourishment of coastal beaches and wetland restoration projects. As the Company enters 2022, we will be focused on strong project performance on work that will help strengthen the U.S. economy and infrastructure, and further support the protection of our U.S. coast lines. This robust market, combined with our diverse and growing fleet, and the start of our growth strategy with our venture into the new U.S. offshore wind market, puts the Company in a solid place to continue the successes experienced in 2021. The Company looks forward to continuing to provide quality work to our clients, a safe work environment for our employees and a positive return for our shareholders for the coming decades.

We committed to build the first U.S.-flagged Jones Act- compliant subsea rock installation vessel by signing a $197 million contract with the Philly Shipyard. Ending the year with a strong backlog, market share and balance sheet we are well-positioned for 2022 and beyond. During this unprecedented pandemic, the health and safety of our employees was and continues to be our top priority. Great Lakes’ Incident & Injury Free® (IIF®) safety management program enabled us to adapt and respond quickly to operational challenges caused by COVID-19. We continued to focus on keeping our ves- sels operating and projects performing, while ensuring the safety of our crews and employees. During 2021, we incurred $9.9 million of costs related to COVID-19 for items such as testing, vessel cleaning, crew quarantining and replacement staffing. In spite of our efforts to keep operations continuing as normal, we had some signifi- cant COVID-19 related production impacts to projects due to crew shortages, vessel dry dock delays, and re- scheduling of vessels. These production impacts are not as easily quantified, but we estimate them to be close to, if not higher than the identifiable costs. As our organiza- tion is now near 100% fully vaccinated against COVID-19, with few accommodations, we are getting back to normal operations even with new strains of the virus emerging. I want to thank all of our staff and crew members for their dedication, perseverance, resiliency, spirit and commit- ment that contributed to our success throughout this challenging year. Together we delivered for our customers and shareholders during a time of great uncertainty. The domestic dredging market for new projects remained relatively strong in 2021 despite the pandemic. We expect this trend to continue with further phases of large-scale port deepening projects along the East and Gulf coasts. Throughout 2021 we performed a significant amount of work in the ports of Boston, Jacksonville, Charleston, Mobile, Freeport, Sabine and Corpus Christi. We also saw increased demand for coastal protection projects, renourishment of coastal beaches that have been damaged after the major hurricane events of the past few years and wetland restoration projects. Infrastructure improvements have been a priority for our political leaders throughout 2021 which resulted in Congress agreeing to another record U.S. Army Corps budget for 2022, an 11% increase over prior year’s record levels. In addition, the U.S. Congress passed the $1.2 trillion infrastructure bill where the Corps will be granted an additional $11.6 billion in funding to improve the nation’s resilience to the effects of climate change, including flood control and waterway dredging. We ended the year with a solid backlog of $551.6 million and a year end bid market share of 40.4%. In November, Great Lakes announced the signing of a $92.5 million dredging contract for the Houston Ship Channel Widening and Improvement Project 11. This is the first phase of the extensive, multi-phase Houston Ship Channel billion-dollar expansion and deepening program. We expect to see the continuation of port deepenings coming to bid in 2022 in the ports of Norfolk, Freeport, Mobile, Sabine, Corpus Christi and additional phases in the Houston ship channel. In 2021, we continued our fleet renewal program to meet increased demand. Our new 6,500 cubic yard mid-size hopper dredge remains on schedule and on budget with expected delivery in the first quarter of 2023. This highly automated new hopper dredge will increase the capabilities of our hopper fleet in the coastal protection and maintenance markets. We have an option to build an additional hopper dredge 2 at the Conrad Shipyard and we expect to make that investment decision mid-2022. We also began the builds of two new multicats support vessels and three new scows which also remain on budget and on schedule for delivery in 2022. In addition, we are upgrading the cutter suction dredge the Carolina and the Company’s largest booster station the Buster to improve NOX and particulate emissions. Our fleet is well equipped to meet current market demand and with our fleet renewal program we expect to be well positioned to meet future market demands. During the year, all projects continued to meet or exceed the established environmental and safety standards. Our goal is to leave the areas that we touch in a better state than when we arrived as a result of the work that we perform. To support this philosophy, we continue to build relationships with all stakeholders, including non-government organizations and con- servation groups, to focus on the protection of our marine environment. Our 2021 ESG Report shares the initiatives we undertook and the progress we achieved in environmental protection and improvements, the safety and well-being of our employees and business partners, our community contributions and partner- ships, fleet improvements, governance practices, and our rapid and thorough response to a global pandemic. Our 2021 Environmental, Social and Governance report can be found on our website at www.gldd.com. In addition to remaining focused on our core business, we solidified our plans to enter the U.S. offshore wind market by signing a contract with Philly Shipyard to build the first U.S.-flagged Jones Act-compliant inclined fallpipe vessel for subsea rock installation with an expected delivery in the second half of 2024. Our new subsea rock installation vessel has been designed to meet the highest environmental classification by ABS. The vessel will be equipped with battery power, a shore-power connection system, and be capable of burning biofuel which will reduce the ship’s CO2 footprint. Designing our new vessels to the highest environmental standards and retrofitting our existing vessels with emission reducing equipment, where practicable, demonstrates our commitment of improving our overall environmental impact. Offshore wind will play a crucial role in helping the U.S. meet its decarbonization and clean energy goals and help reach the Biden administration’s ambitious 30 GW of offshore wind goal by 2030. The unique, technologically advanced vessel we are constructing is an essential step towards building the marine infrastructure required for this new offshore wind industry, which we believe holds so much promise for our nation both economically and environmentally. We believe the offshore wind power generation market will provide Great Lakes with a strong opportunity for growth. We are entering 2022 still uncertain as to the challenges this pandemic will present. However, we are confident in the decisions we made over the past years and are hopeful that these decisions have positioned Great Lakes to perform well financially and operationally. Great Lakes Dredge & Dock Corporation is the United States’ premier dredging company and we will strengthen this position by continuously improving, executing on our projects safely and efficiently, and creating increased shareholder value by delivering solid financial results from our existing dredging business and focusing on our new initiative in offshore wind that will position the company for future. On behalf of the executive leadership team and our Board of Directors, we would like to thank our customers for their trust and you, our shareholders, for your continued commitment and support.

Business Part I The terms “we,” “our,” “ours,” “us,” “Great Lakes” and “Company” refer to Great Lakes Dredge & Dock Corporation and its subsidiaries. Organization Great Lakes is the largest provider of dredging services in the United States. In addition, the Company has a long history of performing significant international projects. The Company was founded in 1890 as Lydon & Drews Partnership and performed its first project in Chicago, Illinois. The Company changed its name to Great Lakes Dredge & Dock Company in 1905 and was involved in a number of marine construction and landfill projects along the Chicago lakefront and in the surrounding Great Lakes region. Great Lakes now provides dredging services in the East and Gulf Coasts of the United States and worldwide. The Company operates in one operating segment, which is also the Company’s sole reportable segment and reporting unit. During the second quarter of 2019, the Company completed the sale of its historical environmental & infrastructure business. The historical environmental & infrastructure segment has been retrospectively presented as discontinued operations and is no longer reflected in continuing operations. Refer to Note 13, “Business dispositions,” to the Company’s consolidated financial statements included in Item 15 of this Annual Report on Form 10-K. Operations Dredging generally involves the enhancement or preservation of the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Domestically, our work generally is performed in coastal waterways and deep water ports. The U.S. dredging market consists of four primary types of work: capital, coastal protection, maintenance and rivers & lakes. The Company’s “bid market” is defined as the aggregate dollar value of domestic dredging projects on which the Company bid or could have bid if not for capacity constraints or other considerations. The Company experienced an average combined bid market share in the U.S. of 37% over the prior three years, including 49%, 55%, 19% and 34% of the domestic capital, coastal protection, maintenance and rivers & lakes sectors, respectively. Over its 131 year history, the Company has grown to be a leader in capital, coastal protection and maintenance dredging in the United States and is one of the oldest and most experienced dredging companies in the country. The Company’s foreign projects are typically categorized in the capital work type, but are not included in the aforementioned bid market. Capital (domestic is 55% of 2021 revenues). Capital dredging consists primarily of port expansion projects, which involve the deepening of channels and berthing basins to allow access by larger, deeper draft ships and the provision of land fill used to expand port facilities. In addition to port work, capital projects also include coastal restoration and land reclamations, trench digging for pipelines, tunnels and cables, and other dredging related to the construction of breakwaters, jetties, canals and other marine structures. Although capital work can be impacted by budgetary constraints and economic conditions, these projects typically generate an immediate economic benefit to the ports and surrounding communities. Coastal protection (23% of 2021 revenues). Coastal protection projects generally involve moving sand from the ocean floor to shoreline locations where erosion threatens shoreline assets. Beach erosion is a continuous problem that has intensified with the rise in coastal development and has become an important issue for state and local governments concerned with protecting beachfront tourism and real estate. Coastal protection via beach 2 nourishment is often viewed as a better response to erosion than trapping sand through the use of sea walls and jetties, or relocating buildings and other assets away from the shoreline. Generally, coastal protection projects take place during the fall and winter months to minimize interference with bird and marine life migration and breeding patterns as well as coastal recreation activities. Maintenance (18% of 2021 revenues). Maintenance dredging consists of the re-dredging of previously deepened waterways and harbors to remove silt, sand and other accumulated sediments. Due to natural sedimentation, most channels generally require maintenance dredging every one to three years, thus creating a recurring source of dredging work that is typically non-deferrable if optimal commercial navigability is to be maintained. In addition, severe weather such as hurricanes, flooding and droughts can also cause the accumulation of sediments and drive the need for maintenance dredging. Foreign (1% of 2021 revenues). Foreign capital projects typically involve land reclamations, channel deepening and port infrastructure development. The Company targets foreign opportunities that are well suited to the Company’s equipment and where it faces reduced competition from its European competitors. Maintaining a presence in foreign markets has enabled the Company to diversify its customer base and take advantage of differences in global economic development. Over the last two decades, the Company has performed dredging work in the Middle East, Africa, Australia, the Caribbean and Central and South America. Rivers & lakes (3% of 2021 revenues). Domestic rivers and lakes dredging and related operations typically consist of lake and river dredging, inland levee and construction dredging, environmental restoration and habitat improvement and other marine construction projects. Although the Mississippi River has a large source of projects on which the Company bids, certain dredges used on these projects are more portable and able to be transported to take advantage of the fragmented market. Generally, inland river and lake projects in the northern U.S. take place in non-winter months because frozen waterways significantly reduce contractors’ ability to operate and transport its equipment in the relevant geographies. Demand Drivers The Company believes that the following factors are important drivers of the demand for its services: • Deep port capital projects. Most of the East Coast and Gulf ports have expansion plans that include deepening and widening in order to better compete for international trade. Many shipping lines have announced plans to deploy larger ships which, due to the channel dimension requirements, currently would not be able to use many U.S. ports. Dredging commenced on two Charleston Entrance Channel projects during 2018 and the Company was successful in securing an additional phase of deepening with all three phases having been completed in 2021. The ports of Los Angeles and Long Beach continue expansion efforts to remain competitive with deepened East Coast ports. Deepening projects in Corpus Christi, Galveston, Freeport, Baltimore and Mississippi were awarded in 2019. In 2020, the Company was awarded port deepening projects in Jacksonville, Freeport, Charleston and Mobile with Jacksonville being completed in 2021. In 2021, Boston, Mobile, Corpus Christi, Portsmouth and Houston port deepening projects were awarded to the Company. The Houston port deepening project is a significant project that will last several years. In 2022, the Company expects to see the continuation of port deepening bids in the ports of Norfolk, Freeport, Mobile, Sabine and additional phases in the Houston ship channel. In addition, during the fourth quarter of 2020, the President signed the Consolidated Appropriations Act, which included the 2020 Water Resource Development Act (the “WRDA 2020”), into law. The WRDA 2020 authorizes new projects and makes policy changes that will make natural infrastructure and beneficial use of dredged material more common. This continues the trend of WRDA legislation in each session of Congress since 2014. The Company views the above as positive catalysts for the domestic dredging industry as it authorizes funding for critical infrastructure improvements that are needed throughout the U.S. Further, the WRDA bills authorize studies for future water resources improvements and make modifications to previous authorizations. 3 The Company believes that port deepening and expansion work authorized under current and anticipated future legislation will continue to provide significant opportunities for the domestic dredging industry. • Gulf coast restoration. There has been continued focus on restoring the barrier islands and wetlands that provide natural protection from storms in the Gulf Coast area. Many restoration projects have commenced to repair coastal areas. Several additional projects are being planned by state and local governments to restore natural barriers. The State of Louisiana has completed a master plan calling for a $50 billion investment in its coastal infrastructure, with a significant portion involving dredging. During 2019, the Company was awarded an additional phase of the Mississippi coastal restoration project in the Gulf of Mexico. In 2020, the Company was awarded two coastal restoration projects in Louisiana by the Louisiana Coastal Protection and Restoration Agency (the “CPRA”) and this work was performed in 2021. The CPRA recently released their fiscal year 2023 plan which included 18 dredging coastal restoration projects that are slated for construction using more than 79 million cubic yards of dredged material to create or nourish over 14,000 acres of coastal wetlands. Many Gulf States have previously committed to spending a portion of the nearly $20 billion in fines received from the 2015 BP settlement of the Deepwater Horizon oil spill to repair the natural resources impacted by the event including coastal restoration projects that include dredging. The bulk of the fines are to be paid over the next decade and the Company expects several coastal restoration projects envisioned by the Gulf States to come to fruition in the next several years providing a new source of domestic capital dredging projects on which the Company will bid. The annual bid market for domestic capital dredging, which includes deep port capital dredging and Gulf Coast restoration, averaged $577 million over the prior three years. • Substantial need for coastal protection. Beach erosion is a recurring problem due to the normal ebb and flow of coastlines as well as the effects of severe storm activity. Growing populations in coastal communities and vital beach tourism are drawing attention to the importance of protecting beachfront assets. Over the past few years, both the federal government and state and local entities have funded beach work recognizing the essential role these natural barriers play in absorbing storm energy and protecting public and private property. With continued funding available for projects in the Northeast from the Superstorm Sandy supplemental appropriations, the Company expects to continue to see an increase in projects let for bid in the coastal protection market. As a result of the extreme storm systems in 2017 involving Hurricanes Harvey, Irma, and Maria, the Federal Government passed supplemental appropriations for disaster relief and recovery which includes $17.4 billion for the U.S. Army Corps of Engineers (the “Corps”) to fund projects that will reduce the risk of future damage from flood and storm events. The Corps is progressing with its plans for this funding, and it is currently believed that over $1.8 billion is expected to be added to its dredging related budget over the next few years. Most of this work is anticipated to be coastal protection related, but some funding has been provided for channel maintenance. During 2019, Congress passed an additional $3.3 billion of supplemental appropriations for disaster relief funding as a result of Hurricane Florence and Hurricane Michael and that work is in process. In September 2021, a supplemental bill was passed that included approximately $5.7 billion for emergency funding as a result of Hurricane Ida impacts. The annual bid market for coastal protection over the prior three years averaged $345 million. • Required maintenance of U.S. ports. The channels and waterways leading to U.S. ports have stated depths on which shippers rely when entering those ports. Due to naturally occurring sedimentation and severe weather, active channels require maintenance dredging to ensure that stated depths are at authorized levels. Consequently, the need to maintain channel depth creates a recurring source of dredging work that is non-deferrable if optimal navigability is to be preserved. The Corps is responsible for federally funded projects related to navigation and flood control of U.S. waterways. The maritime industry, including the ports, has repeatedly advocated for congressional efforts to ensure that a fully funded, recurring maintenance program is in place. As noted above, WRDA 2020 was signed into law during the fourth quarter of 2020. Similar to past versions of the bill, WRDA 2020 language 4 calls for full use of the Harbor Maintenance Trust Fund (“HMTF”) for its intended purpose of maintaining future access to the waterways and ports that support our nation’s economy. The WRDA 2020 legislation also provides access to the $9.3 billion in unspent HMTF tax collections, establishes a funds distribution process for HMTF funding and approves projects to proceed to construction. Additionally, on March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) which includes a provision that lifts caps on the HMTF, thereby allowing full access to future annual revenues. Through the increased appropriation of HMTF monies, the Company anticipates increased funding for harbor maintenance projects to be let for bid and an increase in maintenance dredging projects to be let for bid throughout 2022 and beyond. The House of Representatives passed its version of the Corps fiscal year 2022 budget in July 2021 at $8.66 billion and the Senate passed its version in August 2021 at $8.9 billion. As a result, the Company anticipates the Corps fiscal year 2022 final budget will pass at a record level. Corps projects involving deepening, maintenance and coastal dredging are in line for robust funding continuing the trend of recent years. In both aforementioned budget versions, HMTF annual expenditures are proposed at record levels and with reduced restrictions on the use of the HMTF fund. The annual bid market for maintenance dredging over the prior three years averaged $753 million. • Need to maintain safe navigability of the U.S. river system. There are over 12,000 miles of commercially navigable inland waterways that move more than 566 million tons of commercial goods annually. Transportation by barge requires less energy, and therefore is both better for the environment and a more cost-efficient way to move cargo than transportation by airplane, railcar or truck. Many industries rely on safe navigability of U.S. inland waterways as a primary means to transport goods and commodities such as coal, chemicals, petroleum, minerals, stones, metals and agricultural products. Natural sedimentation and other circumstances require that the inland waterway system be periodically dredged so that it can be used as intended. The Corps recognizes the need to maintain the safe navigability of U.S. waterways. The annual bid market for rivers and lakes dredging over the prior three years averaged $122 million. • Domestic and international energy transportation. The growth in demand for transportation of energy worldwide has driven the need for dredging to support new terminals, harbors, channels and pipelines. In addition, several Liquefied Natural Gas (“LNG”), petrochemical and crude oil projects are creating the need for port development in support of energy exports. The significant drop in crude oil prices during recent years may lead to a slowdown in the development of LNG export plants; however, the Company continues to expect that future global energy demand will necessitate improvements in the infrastructure base around sources of rich resources and in countries that import or export global energy. For additional details regarding Operations, including financial information regarding our international and U.S. revenues and long-lived assets, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Item 8. “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K. Customers The dredging industry’s customers include federal, state and local governments, foreign governments and both domestic and foreign private concerns, such as utilities and oil and other energy companies. Most dredging projects are competitively bid, with the award going to the lowest qualified bidder. Customers generally have few economical alternatives to dredging services. The Corps is the largest dredging customer in the U.S. and has responsibility for federally funded projects related to navigation and flood control. In addition, the U.S. Coast Guard and the U.S. Navy are responsible for awarding federal contracts with respect to their own facilities. In 2021, approximately 78% of the Company’s dredging revenues were generated from 47 different contracts with federal agencies or third parties operating under contracts with federal agencies. 5 As a result of the pandemic outbreak of coronavirus (“COVID-19”), the U.S. Department of Homeland Security federally designated the Company as an essential business or “critical infrastructure” company that can maintain operations during the ongoing pandemic. As mentioned above, the Corps oversees the majority of these critical infrastructure projects and, in this capacity, has continued to follow its bid schedule and prioritize all types of dredging including port maintenance and expansion and coastal protection projects that are necessary to avoid potential storm damage during the current hurricane season. Despite the uncertainty surrounding COVID-19, to date, the Corps is continuing to advertise new projects and the Company’s project work is largely uninterrupted. Bidding Process Most of the Company’s contracts are obtained through competitive bidding on terms specified by the party inviting the bid. The types of equipment required to perform the specified service, project site conditions, the estimated project duration, seasonality, location and complexity of a project affect the cost of performing the contract and the price that dredging contractors will bid. For contracts under its jurisdiction, the Corps typically prepares a fair and reasonable cost estimate based on the specifications of the project. To be successful, a bidder must be determined by the Corps to be a responsible bidder (i.e., a bidder that generally has the necessary equipment and experience to successfully complete the project as well as the ability to obtain a surety bid bond) and submit the lowest responsive bid that does not exceed 125% of the Corps’ original estimate. Contracts for state and local governments are generally awarded to the lowest qualified bidder. Contracts for private customers are awarded based on the contractor’s experience, equipment and schedule, as well as price. While substantially all of the Company’s contracts are competitively bid, some government contracts are awarded through a sole source procurement process involving negotiation between the contractor and the government, while other projects are bid by the Corps through a “request for proposal” process. The request for proposal process benefits both Great Lakes and its customers as customers can award contracts based on factors beyond price, including experience, skill and specialized equipment. Bonding and Foreign Project Guarantees For most domestic projects and some foreign projects, dredging service providers are required to obtain three types of bonds: bid bonds, performance bonds and payment bonds. These bonds are typically provided by large insurance companies. A bid bond is required to serve as a guarantee so that if a service provider’s bid is chosen, the service provider will sign the contract. The amount of the bond is typically 20% of the service provider’s bid, with a range generally between $1 and $10 million. After a contract is signed, the bid bond is replaced by a performance bond, the purpose of which is to guarantee that the job will be completed. If the service provider fails to complete a job, the bonding company would be required to complete the job and would be entitled to be paid the contract price directly by the customer. Additionally, the bonding company would be entitled to be paid by the service provider for any costs incurred in excess of the contract price. A service provider’s ability to obtain performance bonds with respect to a particular contract depends upon the size of the contract, as well as the size of the service provider and its financial position. A payment bond is required to protect the service provider’s suppliers and subcontractors in the event that the service provider cannot make timely payments. Payment bonds are generally written at 100% of the contract value. The Company has bonding agreements with Argonaut Insurance Company, Berkley Insurance Company, Chubb Surety and Liberty Mutual Insurance Company, (collectively, the “Sureties”) under which the Company can obtain performance, bid and payment bonds. The Company also has outstanding bonds with Travelers Casualty and Surety Company of America and Zurich American Insurance Company (“Zurich”). Great Lakes has never experienced difficulty in obtaining bonding for any of its projects and Great Lakes has never failed to complete a marine project in its 131 year history. For most foreign dredging projects, letters of credit or bank guarantees issued by foreign banks are required as security for the bid, performance and, if applicable, advance 6 payment guarantees. The Company obtains its letters of credit under the Amended Credit Agreement (as defined below). Foreign bid guarantees are usually 2% to 5% of the service provider’s bid. Foreign performance and advance payment guarantees are each typically 5% to 10% of the contract value. Competition The U.S. dredging industry is highly fragmented with approximately 250 entities in the U.S. presently operating more than 850 dredges, primarily in maintenance dredging. Most of these dredges are smaller and service the inland, as opposed to coastal, waterways, and therefore do not generally compete with Great Lakes except in our rivers & lakes market. Competition is determined by the size and complexity of the job; equipment bonding and certification requirements; and government regulations. Competition on rivers & lakes projects is determined primarily based on geographic reach, project execution capability and price. Great Lakes and three other companies comprised approximately 80% of the Company’s defined bid market related to domestic capital, coastal protection, maintenance and rivers & lakes over the prior three years. Within the Company’s bid market, competition is determined primarily on the basis of price. In addition, the Foreign Dredge Act of 1906 (the “Dredging Act”) and Section 27 of the Merchant Marine Act of 1920 (the “Jones Act”) provide significant barriers to entry with respect to foreign competition. Together these two laws prohibit foreign-built, chartered or operated vessels from competing in the U.S. See “Business—Government Regulations” below. Competition in the international market is dominated by four large European dredging companies all of which operate larger equipment and fleets that are more extensive than the Company’s fleet. Additionally, a large Chinese dredging company has emerged as a key player in the international market. There are also several governmentally supported dredging companies that operate on a local or regional basis. The Company targets opportunities that are well suited to its equipment and where it can be most competitive. Equipment Great Lakes’ fleet of dredges, material barges and other specialized equipment is the largest and most diverse in the U.S. The Company operates three principal types of dredging equipment: hopper dredges, hydraulic dredges and mechanical dredges. Hopper Dredges. Hopper dredges are typically self-propelled and have the general appearance of an ocean- going vessel. The dredge has hollow hulls, or “hoppers,” into which material is suctioned hydraulically through drag-arms. Once the hoppers are filled, the dredge sails to the designated disposal site and either (i) bottom dumps the material or (ii) pumps the material from the hoppers through a pipeline to a designated site. Hopper dredges can operate in rough waters, are less likely than other types of dredges to interfere with ship traffic, and can be relocated quickly from one project to another. Hopper dredges primarily work on coastal protection and maintenance projects. The Company is currently building a 6,500 cubic yard trailing suction hopper dredge with expected delivery in the first quarter of 2023. Hydraulic Dredges. Hydraulic dredges remove material using a revolving cutterhead which cuts and churns the sediment on the channel or ocean floor and hydraulically pumps the material by pipe to the disposal location. These dredges are very powerful and can dredge some types of rock. Certain dredged materials can be directly pumped for miles with the aid of multiple booster pumps. Hydraulic dredges work with an assortment of support equipment, which help with the positioning and movement of the dredge, handling of the pipelines and the placement of the dredged material. Unlike hopper dredges, relocating hydraulic dredges and all their ancillary equipment requires specialized vessels and additional time, and their operations can be impacted by ship traffic and rough waters. There is a wide range of hydraulic dredges from our smaller rivers & lakes vessels that use pipe sizes ranging from 10” to 22” and operate at between 365 and 3,200 total horsepower, while the Company’s other hydraulic dredges use pipe sizes ranging from 18” to 30” and operate at between 1,900 and 16,650 total horsepower. 7 Mechanical Dredges. There are two basic types of mechanical dredges: clamshell and backhoe. In both types, the dredge uses a bucket to excavate material from the channel or ocean floor. The dredged material is placed by the bucket into material barges, or “scows,” for transport to the designated disposal area. The scows are emptied by bottom-dumping, direct pump-out or removal by a crane with a bucket. The backhoe dredge is capable of removing hard-packed sediments, blasted rock and debris and can work in tight areas such as along docks or terminals. Clamshell dredges with specialized buckets are ideally suited to handle softer silts and maintenance material requiring environmentally controlled excavation and disposal. Additionally, the Company owns an electric clamshell dredge which provides an advantage in those markets with stringent emissions standards. Scows. The Company has the largest fleet of material barges in the domestic industry, which provides cost advantages when dredged material is required to be disposed far offshore or when material requires controlled disposal. The Company uses scows with its hydraulic dredges and mechanical dredges. Scows are an efficient and cost-effective way to move material and increase dredging production. The Company has twelve scows in its fleet with a capacity ranging from 5,000 to 8,800 cubic yards. The Company is currently in the process of building three new scows, each 7,100 cubic yards in size, with expected delivery in 2022. In addition, the Company has numerous pieces of smaller equipment that support its dredging operations. Great Lakes’ domestic dredging fleet is typically positioned on the East and Gulf Coasts, with a smaller number of vessels occasionally positioned on the West Coast, and with many of the rivers & lakes dredges on inland rivers and lakes. The mobility of the fleet enables the Company to move equipment in response to changes in demand. The Company continually assesses its need to upgrade and expand its dredging fleet to take advantage of improving technology and to address the changing needs of the dredging market. The Company is also committed to a reliability-assured maintenance program, which it believes is reflected in the long lives of most if its equipment and its low level of unscheduled downtime on jobs. To the extent that market conditions warrant the expenditures, Great Lakes can prolong the useful life of its vessels. Certification of equipment by the U.S. Coast Guard and establishment of the permissible loading capacity by the American Bureau of Shipping (“A.B.S.”) are important factors in the Company’s dredging business. Many projects, such as coastal protection projects with offshore sand borrow sites and dredging projects in exposed entrance channels or with offshore disposal areas, are restricted by federal regulations to be performed only by dredges or scows that have U.S. Coast Guard certification and a load line established by A.B.S. The certifications indicate that the dredge is structurally capable of operating in open waters. The Company has more certified dredging vessels than any of the Company’s domestic competitors and makes substantial investments to maintain these certifications. Seasonality Seasonality generally does not have a significant impact on the Company’s operations. However, many East Coast coastal protection projects are limited by environmental windows that require work to be performed in winter months to protect wildlife habitats. The Company can mitigate the impact of these environmental restrictions to a certain extent because the Company has the flexibility to reposition its equipment to project sites, if available, that are not limited by these restrictions. In addition, rivers and lakes in the northern U.S. freeze during the winter, significantly reducing the Company’s ability to operate and transport its equipment in the relevant geographies. Fish spawning and flooding can affect dredging operations as well. Weather The Company’s ability to perform its contracts may depend on weather conditions. Inclement or hazardous weather conditions can delay the completion of a project, can result in disruption or early termination of a 8 project, unanticipated recovery costs or liability exposure and additional costs. As part of bidding on fixed-price contracts, the Company makes allowances, consistent with historical weather data, for project downtime due to adverse weather conditions. In the event that the Company experiences adverse weather beyond these allowances, a project may require additional days to complete, resulting in additional costs and decreased gross profit margins. Conversely, favorable weather can accelerate the completion of the project, resulting in cost savings and increased gross profit margins. Typically, Great Lakes is exposed to significant weather in the first and fourth quarters, and certain projects are required to be performed in environmental windows that occur during these periods. See “Business-Seasonality” above. Weather is difficult to predict and historical records exist for only the last 100-125 years. Changes in weather patterns may cause a deviation from project weather allowances on a more frequent basis and consequently increase or decrease gross profit margin, as applicable, on a project-by-project basis. In a typical year, the Company works on many projects in multiple geographic locations and experiences both positive and negative deviations from project weather allowances. Backlog The Company’s contract backlog represents its estimate of the revenues that will be realized under the portion of the contracts remaining to be performed. These estimates are based primarily upon the time and costs required to mobilize the necessary assets to and from the project site, the amount and type of material to be dredged and the expected production capabilities of the equipment performing the work. However, these estimates are necessarily subject to variances based upon actual circumstances. Because of these factors, as well as factors affecting the time required to complete each job, backlog is not always indicative of future revenues or profitability. In addition, a significant amount of the Company’s backlog relates to federal government contracts, which can be canceled at any time without penalty, subject to the Company’s right, in some cases, to recover the Company’s actual committed costs and profit on work performed up to the date of cancellation. The Company’s backlog may fluctuate significantly from quarter to quarter based upon the type and size of the projects the Company is awarded from the bid market. A quarterly increase or decrease of the Company’s backlog does not necessarily result in an improvement or a deterioration of the Company’s business. The Company’s backlog includes only those projects for which the Company has obtained a signed contract with the customer. The components of the Company’s backlog including dollar amount and other related information are addressed in more detail in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Bidding Activity and Backlog.” Human Capital Management At December 31, 2021, the Company employed 413 full-time salaried personnel in the U.S., including those in a corporate function. In addition, the Company employs U.S. hourly personnel, most of whom are unionized, on a project-by-project basis. Crews are generally available for hire on relatively short notice. During 2021, the Company employed an average of approximately 818 hourly personnel to meet domestic project requirements. At December 31, 2021, the Company employed 6 foreign nationals and 2 local staff to manage and administer its Middle East operations. During 2021, the Company also employed an average of 2 hourly personnel to meet project requirements in the Middle East. We seek to identify, recruit, retain, incentivize and integrate our existing and future employees. To achieve our goal of attracting and retaining the most talented employees in the industry, we offer competitive compensation and benefits that support their physical, financial, and emotional health. The principal objective of our equity incentive plans is to attract, retain and motivate selected employees and directors through the granting of stock-based compensation awards. We offer employees benefits including a 401(k) plan with employer contributions; health, life, and disability insurance; additional voluntary insurance; paid time off and parental leave; and paid counseling assistance. 9 Safety Safety of its employees is one of the Company’s core values. The Company employs behavioral and system- based programs utilizing an Incident & Injury Free® (IIF®) approach. The Company’s safety culture is committed to training, behavioral based awareness and mutual responsibility for the wellbeing of its employees. The Company’s goal is sustainable safety excellence. Incident prevention in all areas has top priority in the Company’s business planning, in the overall conduct of its business, and in the operation and maintenance of our equipment (marine and land) and facilities. During the ongoing COVID-19 pandemic, the health and safety of our employees are our primary goal. Our commitment to health and safety during the pandemic reaches for beyond our employees and embraces their families, our customers, and our community. The unique nature of our business requires many of our employees to live and work in close proximity to one another. We have instituted and strictly adhere to rigorous measures designed to provide our employees with a safe working environment and allow them to safely execute tasks. We follow enhanced safety and health protocols—including screenings, social distancing, and use of personal protective equipment. We have mandated and strictly implemented a robust at-home virus testing program, and mandate virus testing before boarding our vessels and before leaving our vessels. Access to all of our facilities is restricted to only those persons who have been vaccinated against COVID-19 or have received an accommodation. Pre-access and periodic COVID-19 testing is mandatory. Relocation of our Corporate Headquarters In October 2020, we announced that we would relocate our headquarters from Oakbrook Terrace, Illinois to Houston, Texas. We began the transition of key members of the management team to Houston in January 2021. Further transition of key personnel is ongoing. While one of the objectives of the relocation was improving our ability to secure more public and private business opportunities in our core coastal areas, including the Gulf of Mexico, our relocation also provides us access to a unique talent pool that has roots in the maritime industries as well as world class engineering experience and innovation. Access to research and development initiatives at Texas A&M University, boasting the only dredging-focused course of study in the United States, is only 90 miles away, and two other campuses with emphasis on coastal and offshore studies are also nearby. The region is known for its robust community college and technical school system that provides skilled labor and training to the maritime trades. Our new Houston location will allow us to increase our engagement with other local maritime businesses, giving us the opportunity to learn and improve by sharing the best industry practices for safety, operations, and innovation. Unions The Company is a party to numerous collective bargaining agreements in the U.S. that govern its relationships with its unionized hourly workforce. However, two unions represent a large majority of our dredging employees - the International Union of Operating Engineers (“IUOE”) Local 25 and the Seafarers International Union. The Company’s master and ancillary contracts with IUOE Local 25 expire in September 2024. Our agreements with Seafarers International Union expire in February 2023. The Company has not experienced any major labor disputes in the past five years and believes it has good relationships with the unions that represent a significant number of its hourly employees; however, there can be no assurances that the Company will not experience labor strikes or disturbances in the future. Government Regulations The Company is subject to government regulations pursuant to the Dredging Act, the Jones Act, the Shipping Act, 1916 (the “Shipping Act”) and the vessel documentation laws set forth in Chapter 121 of Title 46 of the United States Code. These statutes require vessels engaged in dredging in the navigable waters of the United States to be documented with a coastwise endorsement, to be owned and controlled by U.S. citizens, to be manned by U.S. crews, and to be built in the United States. The U.S. citizen ownership and control standards 10 require the vessel-owning entity to be at least 75% U.S. citizen owned and prohibit the chartering of the vessel to any entity that does not meet the 75% U.S. citizen ownership test. Environmental Matters The Company’s operations, facilities and vessels are subject to various environmental laws and regulations related to, among other things: dredging operations; the disposal of dredged material; protection of wetlands; storm water and waste water discharges; demolition activities; asbestos removal; transportation and disposal of wastes and materials; air emissions; and remediation of contaminated soil, sediments, surface water and groundwater. The Company is also subject to laws designed to protect certain marine species and habitats. Compliance with these statutes and regulations can delay appropriation and/or performance of particular projects and increase related project costs. Non-compliance can also result in fines, penalties and claims by third parties seeking damages for alleged personal injury, as well as damages to property and natural resources. Certain environmental laws such as the U.S. Comprehensive Environmental Response, Compensation and Liability Act of 1980, the Clean Water Act and the Oil Pollution Act of 1990 impose strict and, under some circumstances joint and several, liability on owners and operators of facilities and vessels for investigation and remediation of releases and discharges of regulated materials, and also impose liability for related damages to natural resources. The Company’s past and ongoing operations involve the use, and from time to time the release or discharge, of regulated materials which could result in liability under these and other environmental laws. The Company has remediated known releases and discharges as deemed necessary, but there can be no guarantee that additional costs will not be incurred if, for example, third party claims arise or new conditions are discovered. The Company’s projects may involve remediation, demolition, excavation, transportation, management and disposal of hazardous waste and other regulated materials. Various laws strictly regulate the removal, treatment and transportation of hazardous water and other regulated materials and impose liability for human health effects and environmental contamination caused by these materials. The Company takes steps to limit its potential liability by hiring qualified subcontractors from time to time to remove such materials from our projects, and some project contracts require the client to retain liability for hazardous waste generation. Based on the Company’s experience and available information, the Company believes that the future cost of compliance with existing environmental laws and regulations (and liability for known environmental conditions) will not have a material adverse effect on the Company’s business, financial position, results of operations or cash flows. However, the Company cannot predict what environmental legislation or regulations will be enacted in the future, how existing or future laws or regulations will be enforced, administered or interpreted, or the amount of future expenditures that may be required to comply with these environmental or health and safety laws or regulations or to respond to newly discovered conditions, such as future cleanup matters or other environmental claims.

Risks Related to the COVID-19 Pandemic In December 2019, a novel strain of coronavirus (COVID-19) was reported to have surfaced in Wuhan, China. COVID-19 has since spread worldwide and to every state in the United States. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic and on March 13, 2020 the United States declared a national emergency in response to the COVID-19 outbreak. This outbreak has severely impacted global economic activity and many countries and states in the United States have reacted by instituting quarantines, mandating school and business closures and limiting travel. Our clients, the Corps, private clients and other federal or state agencies, have been impacted by the COVID-19 pandemic. These impacts have led to delays in some of our projects. If the pandemic is prolonged, it may lead to additional delays or cancelations in current or future projects. Funds for dredging projects may also be diverted for public health, economic, or other priorities. Even after the COVID-19 pandemic has subsided, we may experience adverse impacts to our business as a result of its effect on global economies and financial markets, including any recession or economic downturn that has occurred or may occur in the future. In addition to project delays, the COVID-19 pandemic may affect, our business, including, but not limited to, in the following ways: • While much of our client base is federal, state, or other governmental entities, some of our clients may be unable to meet their payment obligations to us in a timely manner, including as a result of deteriorating financial conditions or bankruptcy resulting from the COVID-19 pandemic and resulting economic impacts. Further, other third parties, such as suppliers, subcontractors, and other outside business partners, may experience significant disruptions in their ability to fulfill their obligations toward us, or they may not be unable to fulfill their obligations to us at all. • Much of our work is conducted on vessels, where our crew is required to live for extended periods of time. We have experienced, and may continue to experience, temporary work stoppages because of viral outbreaks on board our vessels. Temporary work stoppages may lead to decreased revenue and affect our ability to timely and satisfactorily complete our clients’ projects. • The Biden Administration has issued an executive order, that while currently stayed, requires federal contractors to, among other things, ensure the vaccination of all employees against COVID-19, and to require all subcontractors to do the same. If these, or other federal, state or local government mandates are reinstated or enacted, we may not be able to find employees and subcontractors who will qualify under then-in-effect mandate requirements, which may impair our ability to successfully perform federal contracts. • Our vaccination requirements have limited, and may continue to result in limiting our ability to find qualified personnel to perform the duties required under our contracts. • Viral outbreaks on board our vessels have required us, and may continue to require us, to incur additional expenses to protect the health and safety of our employees, our clients, and other business partners. These costs include regular, mandated testing for our employees before they leave their homes and travel to the vessel, before they board the vessel, and before they leave the vessel to return home; disinfection of vessels; costs associated with accommodations for crew members who are quarantined or otherwise unable to board a vessel or return home; and overtime costs associated with the extended length of time crew members may be required to work or be available because of COVID-19 safety measures. 16 • In addition to existing travel restrictions implemented in response to the COVID-19 pandemic, jurisdictions may continue to close borders, impose prolonged quarantines and further restrict travel and business activity, which could impair our ability to support our operations and clients (both domestic and international), to source supplies through the global supply chain and to identify, pursue and capture new business opportunities, and which could restrict the ability of our employees to access their workplaces. We also face the possibility of increased overhead or other expenses resulting from compliance with any future government orders or other measures enacted in response to the COVID-19 pandemic. • COVID-19 travel restrictions have limited, and may continue to limit, the ability of our senior personnel to conduct on-site project visits, which may lead to operational inefficiencies and may negatively impact the performance of our projects. We are unable at this time to quantify the extent to which the continued global spread of the COVID-19 pandemic may adversely affect our business, financial condition, and results of operations, including the duration and magnitude of such impacts. The impacts from this unprecedented global event will depend on numerous evolving factors that we may not be able to accurately predict or assess. COVID-19, and the volatile regional and global economic conditions stemming from the pandemic, as well as reactions to future pandemics or resurgences of COVID-19, could also precipitate or aggravate the other risk factors that we identify in this Annual Report on Form 10-K, which in turn could materially adversely affect our business, financial condition and results of operations. There may be other adverse consequences to our business, financial condition and results of operations from the spread of COVID-19 that we have not considered or have not become apparent. As a result, we cannot assure you that if the COVID-19 pandemic persists or worsens, it would not have an adverse impact on our business, financial condition and results of operations. Risks Related to our Business A reduction in government funding for dredging or other contracts, or government cancellation of such contracts, could materially adversely affect our business operations, revenues and profits. A substantial portion of our revenue is derived from federal government contracts, particularly dredging contracts. Revenues related to dredging contracts with federal agencies or companies operating under contracts with federal agencies and the percentage as a total of dredging revenue for the years ended December 31, 2021, 2020 and 2019 were as follows: Federal government revenue (in US $1,000) Percent of revenue from federal government $568,980 $582,949 $581,157 78% 79% 82% Year Ended December 31, 2021 2020 2019 Amounts spent by the federal government on dredging are subject to the budgetary and legislative processes. We would expect the federal government to continue to improve and maintain ports as it has for many years, which will necessitate a certain level of federal spending. However, there can be no assurance that the federal government will allocate any particular amount or level of funds to be spent on dredging projects for any specified period. In addition, Congress must approve budgets that govern spending by many of the federal agencies we support. When Congress is unable to agree on budget priorities, and thus is unable to pass the annual budget on a timely basis, Congress typically enacts a continuing resolution. A continuing resolution allows U.S. federal government agencies to operate at spending levels approved in the previous budget cycle. Under a continuing resolution, funding may not be available for new projects or may be delayed on current projects. Any such funding delays would likely result in new projects being delayed or canceled and could have a material adverse effect on our revenue and operating results. Furthermore, a failure to complete the budget process and fund government operations pursuant to a continuing resolution may result in a U.S. federal government 17 shutdown. An extended shutdown may result in us incurring substantial costs without reimbursement under our contracts and the delay or cancellation of key projects, which could have a material adverse effect on our revenue and operating results. In addition, potential contract cancellations, modifications, protests, suspensions or terminations may arise from resolution of these issues and could cause our revenues, profits and cash flows to be lower. Federal government contracts can be canceled at any time without penalty to the government, subject to, in most cases, our contractual right to recover our actual committed costs and profit on work performed up to the date of cancellation. Accordingly, there can be no assurance that the federal government will not cancel any federal government contracts that have been or are awarded to us. Even if a contract is not cancelled, the government may elect to not award further work pursuant to a contract. There is no guarantee that the current Administration will not divert funds away from the Corps or from our other customers relying on funding from the federal government. There is also no guarantee that additional national emergencies will not be declared in the future. A significant reduction in government funding for dredging or remediation contracts 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. The U.S. government and various state, local and foreign government agencies conduct rigorous competitive processes for awarding many contracts. Some contracts include multiple award task order contracts in which several contractors are selected as eligible bidders for future work. We will face strong competition and pricing pressures for any additional contract awards from the U.S. government and other domestic and foreign government agencies, and we may be required to qualify or continue to qualify under various multiple award task order contract criteria. Further, much of our work depends on our compliance with environmental and other regulations. Any claim by the government that we have violated any laws or regulations could result in our suspension or debarment from bidding for or being awarded government contracts. Our inability to qualify as an eligible bidder under government contract criteria could preclude us from competing for certain government contract awards. In addition, our inability to qualify as an eligible bidder, or to compete successfully when bidding for certain government contracts and to win those contracts, could materially adversely affect our business, operations, revenues and profits. 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. We conduct our business under various types of contracts where costs are estimated in advance of our performance. Most dredging contracts are fixed-price contracts where the customer pays a fixed price per unit (e.g., cubic yard) of material dredged. Fixed-price contracts carry inherent risks, including risks of losses from underestimating costs, operational difficulties, and other changes that can occur over the contract period. If our estimates prove inaccurate, if there are errors or ambiguities as to contract specifications, or if circumstances change due to, among other things, unanticipated conditions or technical problems, difficulties in obtaining permits or approvals, changes in local laws or labor conditions, inclement or hazardous weather conditions, changes in cost of equipment or materials, or our suppliers’ or subcontractor’s inability to perform, then cost over-runs and delays in performance are likely to occur. We may not be able to obtain compensation for additional work performed or expenses incurred, or may be delayed in receiving necessary approvals or payments. Additionally, we may be required to pay liquidated damages upon our failure to meet schedule or performance requirements of our contracts. If we were to significantly underestimate the costs on one or more significant contracts, the resulting losses could have a material adverse effect on our business, operating results, cash flows or financial condition. 18 Our quarterly and annual operating results may vary significantly based on the timing of contract awards and performance. Our quarterly and annual results of operations have fluctuated from period to period in the past and may continue to fluctuate in the future. Accordingly, you should not rely on the results of any past quarter or quarters as an indication of future performance in our business operations or valuation of our stock. Our operating results could vary greatly from period to period due to factors such as: • • • • • the timing of contract awards and the commencement or progress of work under awarded contracts; inclement or hazardous weather conditions that may result in underestimated delays in dredging, disruption or early termination of projects, unanticipated recovery costs or liability exposure, and additional contract expenses; planned and unplanned equipment downtime, or equipment mobilization to and from projects, including those due to the impacts of COVID-19; our ability to recognize revenue from pending change orders, which is recognized only when the parties to a contract approve a modification that either creates new, or changes existing, enforceable rights and obligations of the parties to the contract; and environmental restrictions requiring that certain projects be performed in winter months to protect wildlife habitats. If our results of operations from quarter to quarter fail to meet the expectations of public market analysts and investors, our stock price could be negatively impacted. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Primary Factors that Determine Operating Profitability.” If we fail to comply with government contracting regulations, we could be subject to significant potential liabilities and loss of revenue. Our contracts with federal, state, local and foreign governmental customers are subject to various procurement regulations and contract provisions. These regulations also subject us to examinations by government auditors and investigators, from time to time, to ensure compliance and to review costs. Violations of government contracting regulations could result in the imposition of civil and criminal penalties, which could include termination of contracts, forfeiture of profits, imposition of payments and fines and suspension or debarment from future government contracting. If we fail to continue to qualify for or are suspended from work under a government contract for any reason, we could suffer a material adverse effect on our business, operating results, cash flows or financial condition. In addition, we may be subject to litigation brought by private individuals on behalf of the government relating to our government contracts, referred to in this annual report as “qui tam” actions, which could include claims for up to treble damages. Qui tam actions are sealed by the court at the time of filing. The only parties privy to the information in the complaint are the complainant, the U.S. government and the court. Therefore, it is possible that qui tam actions have been filed against us and that we are not aware of such actions or have been ordered by the court not to discuss them until the seal is lifted. Thus, it is possible that we are subject to liability exposure arising out of qui tam actions. 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. Capital expenditures and other costs necessary to operate and maintain our vessels tend to increase with the age of the vessel. Accordingly, it is likely that the operating costs of our vessels will increase. 19 The average age of our more significant vessels as of December 31, 2021, by equipment type, is as follows: Type of Equipment Hydraulic Dredges Hopper Dredges Mechanical Dredges Unloaders Drillboats Material and Other Barges Total Average Age in Years Quantity 8 5 5 1 1 107 127 43 30 49 38 38 20 23 Remaining economic life has not been presented, because it is not reasonably quantifiable. That is because, to the extent that market conditions warrant the expenditures, we can prolong the vessels’ lives. In our domestic market, we operate in an industry where a significant portion of our competitors’ equipment is of a similar age. It is common in the dredging industry to make maintenance and capital expenditures in order to extend the economic life of equipment. In addition, changes in governmental regulations, safety or other equipment standards, as well as compliance with standards imposed by maritime self-regulatory organizations, standards imposed by vessel classification societies and customer requirements or competition, may require us to make significant additional expenditures. For example, if the U.S. Coast Guard enacts new standards, we may be required to incur expenditures for alterations or the addition of new equipment (e.g. more fuel-efficient engines). In order to satisfy any such requirements, we may need to take our vessels out of service for extended periods of time, with corresponding losses of revenues. Equipment or mechanical failures could result in increased costs, project delays and reduced revenues. The successful performance of contracts requires a high degree of reliability of our vessels, barges and other equipment. The average age of our marine fleet as of December 31, 2021 was 23 years. Breakdowns not only add to the costs of executing a project, but they can also delay the completion of subsequent contracts, which are scheduled to utilize the same assets. We operate a scheduled maintenance program in order to keep all assets in good working order, but despite this, breakdowns can and do occur, resulting in loss of revenue. A pandemic, epidemic or outbreak of an infectious disease affecting our markets or impacting our facilities or suppliers could adversely impact our business. If another pandemic, epidemic, or outbreak of an infectious disease or other public health crisis, including an unexpected increase in COVID-19 infections, were to affect our markets or facilities or those of our suppliers, our business could be adversely affected. Another pandemic or the continuation or an increase of the current COVID-19 pandemic could cause disruptions in and restrictions on our ability to travel, and in the future these disruptions and restrictions could restrict our ability to perform work for future projects in different locations. If an infectious disease were to have a widespread outbreak at one or more of our vessels or facilities, our operations may be affected significantly, our productivity may be affected, key personnel necessary to conduct our operations or replacement crew may be unavailable, our ability to complete projects in accordance with our contractual obligations may be affected, and we may incur increased labor and materials costs. If the shipyards with which we contract were affected by an outbreak of infectious disease, repairs of our vessels as well as new construction may be delayed and we may incur increased labor and materials costs. In addition, we may experience difficulties with certain suppliers or with vendors in their supply chains, and our business could be affected if we become unable to procure essential supplies or services in adequate quantities and at acceptable prices. 20 Our clients, which are the Corps, private clients and other federal, state or local agencies, may be impacted by a pandemic, and if prolonged, these impacts may lead to cancelations or delays in projects. Funds for dredging projects may also be diverted for public health, economic, or other priorities. Overall, the potential impact of a pandemic, epidemic or outbreak of an infectious disease with respect to our markets or our facilities is difficult to predict and could adversely impact our business. Disruptions to our supply chain affecting our markets or impacting our facilities or suppliers could prohibit procurement of new vessel build materials and adversely impact our business. Supply chain issues could cause disruptions that restrict our ability to perform work for future projects. Our ability to complete projects in accordance with our contractual obligations may be affected, and we may incur increased labor and materials costs. If the shipyards with which we contract are affected, repairs of our vessels as well as new construction may be delayed and we may incur increased labor and materials costs. In addition, we may experience difficulties with certain suppliers or with vendors in their supply chains, and our business could be affected if we become unable to procure essential supplies or services in adequate quantities and at acceptable prices. Our international dredging operations subject us to competitive, political, regulatory and other risks. Revenue from foreign contracts and its percentage to total dredging revenue for the years ended December 31, 2021, 2020 and 2019 were as follows: Foreign revenue (in US $1,000) Percent of revenue from foreign countries Year Ended December 31, 2021 2020 2019 $6,596 $25,892 $48,619 1% 4% 7% The international dredging market is highly competitive, and competition in the international market is dominated by four large European dredging companies, all of which operate larger equipment and fleets that are more modern and extensive than the Company’s. In addition, there are several governmentally supported dredging companies that operate on a local or regional basis. Competing for international dredging projects requires a substantial investment of resources, skilled personnel and capital investment in equipment and technology, and may adversely affect our ability to deploy resources for domestic dredging projects. International operations subject us to additional potential risks, including: • • • • • • • • • • uncertainties concerning import and export license requirements, tariffs and other trade barriers; political and economic instability and risks of terrorist activities; reduced demand as a result of fluctuations in the price of oil, the primary export in the Middle East; difficulties in enforcing contractual rights and agreements through certain foreign legal systems; requirements of, and changes in, foreign laws, policies and regulations; local licensing, permitting and royalty issues, particularly with respect to our overseas operations in Bahrain and the Middle East; difficulties in staffing and managing international operations without additional expense; taxation issues; greater difficulty in accounts receivable collection and longer collection periods; compliance with the U.S. Foreign Corrupt Practices Act and international anticorruption laws; 21 • • • currency fluctuations; logistical and communication challenges; and inability to effectively insure against political, cultural and economic uncertainties, including acts of terrorism, civil unrest, war or other armed conflict. In addition, our international operations are subject to U.S. and other laws and regulations regarding operations in foreign jurisdictions. These numerous and sometimes conflicting laws and regulations include anti- boycott laws, anti-competition laws, anti-corruption laws, tax laws, immigration laws, privacy laws and accounting requirements. There is a risk that some provisions may be breached, for example through inadvertence or mistake, fraudulent or negligent behavior of individual employees or of agents, or failure to comply with certain formal documentation requirements or otherwise. Violations of these laws and regulations could result in fines and penalties, criminal sanctions against us, our officers, or our employees, prohibitions on the conduct of our business and on our ability to operate in one or more countries, which could have a material adverse effect on our business, results of operations or financial condition. In addition, military action, terrorist activities or continued unrest in the Middle East could affect the safety of our personnel in the region and significantly increase the costs of, or disrupt our operations in, the region and could have a material adverse effect on our business, operating results, cash flows or financial condition. Regional instability in the Middle East may adversely affect business conditions and may disrupt our operations. Saudi Arabia, Bahrain and other Middle East countries have experienced political turbulence in the recent past. Political uprisings and conflicts, including armed hostilities and civil unrest, may affect the political stability of the region. Tensions in the region between the U.S. and Iran have escalated, resulting in increased military and militia activity in Iraq and other Middle East countries. In addition, there has been a decline in the relationships between and amongst certain governments in the Middle East, such as continued conflicts between Saudi Arabia and Iran. Deterioration in the political, economic, and social conditions or other relevant policies of the government, such as changes in laws or regulations, export restrictions, expropriation of our assets or resource nationalization, could materially and adversely affect our business, access to markets, financial condition, and results of operations. Similar civil unrest and political turbulence has occurred in other countries in the region. In addition, such events may affect plans for infrastructure investment. If the government changes or significant restrictions are established, our dredging operations in the Middle East, including the value of our assets related to such operations, may be adversely affected. Environmental regulations could force us to incur capital and operational costs. Our industries, and more specifically, our operations, facilities and vessels and equipment, are subject to various environmental laws and regulations relating to, among other things: dredging operations; the disposal of dredged material; protection of wetlands; storm water and waste water discharges; transportation and disposal of hazardous wastes and other regulated materials; air emissions; and disposal or remediation of contaminated soil, sediments, surface water and groundwater. We are also subject to laws designed to protect certain marine or land species and habitats. Compliance with these statutes and regulations can delay permitting and/or performance of particular projects and increase related project costs. These delays and increased costs could have a material adverse effect on our business, results of operations, cash flows or financial condition. Non-compliance can also result in fines, penalties and claims by third parties seeking damages for alleged personal injury, as well as damages to property and natural resources and suspension or debarment from future government contracting. 22 Certain environmental laws such as the U.S. Comprehensive Environmental Response, Compensation and Liability Act of 1980 and the Oil Pollution Act of 1990 impose strict and, under some circumstances, joint and several, liability on owners and lessees of land and facilities as well as owners and operators of vessels. Such obligations may include investigation and remediation of releases and discharges of regulated materials, and also impose liability for related damages to natural resources. Our past and ongoing operations involve the use, and from time to time the release or discharge, of regulated materials which could result in liability under these and other environmental laws. We have remediated known releases and discharges as deemed necessary, but there can be no guarantee that additional costs will not be incurred if, for example, third party claims arise or new conditions are discovered. Our projects may involve excavation, remediation, demolition, transportation, management and disposal of hazardous waste and other regulated materials. Various laws strictly regulate the removal, treatment and transportation of hazardous waste and other regulated materials and impose liability for human health effects and environmental contamination caused by these materials. Services rendered in connection with hazardous substance and material removal and site development may involve professional judgments by licensed experts about the nature of soil conditions and other physical conditions, including the extent to which hazardous substances and materials are present, and about the probable effect of procedures to mitigate problems or otherwise affect those conditions. If the judgments and the recommendations based upon those judgments are incorrect, we may be liable for resulting damages, which may be material. The failure of certain contractual protections to protect us from incurring such liability, such as staying out of the ownership chain for hazardous waste and other regulated materials and securing indemnification obligations from our customers or subcontractors, could have a material adverse effect on our business, results of operations, revenues or profits. Environmental requirements have generally become more stringent over time, for example in the areas of air emissions controls for vessels and ballast treatment and handling. New laws or stricter enforcement of existing laws or, the discovery of currently unknown conditions or accidental discharges of regulated materials in the future could cause us to incur additional costs for environmental matters which might be significant. We may be affected by market or regulatory responses to climate change. Increased concern about the potential impact of greenhouse gases (“GHG”), such as carbon dioxide resulting from combustion of fossil fuels, on climate change has resulted in efforts to regulate their emission. Legislation, international protocols, regulation or other restrictions on GHG emissions could also affect our customers. Such legislation or restrictions could increase the costs of projects for our customers or, in some cases, prevent a project from going forward, thereby potentially reducing the need for our services which could in turn have a material adverse effect on our operations and financial condition. Additionally, in our normal course of operations, we use a significant amount of fossil fuels. The costs of controlling our GHG emissions or obtaining required emissions allowances in response to any regulatory change in our industry could increase materially. Penalties for late completion of contracts could reduce our profits. In many instances, including in our fixed-price contracts, we guarantee that we will complete a project by a scheduled date. If we subsequently fail to complete the project as scheduled, we may be liable for any customer losses resulting from such delay, generally in the form of contractually agreed-upon liquidated damages. In addition, failure to maintain a required schedule could cause us to default on our government contracts, giving rise to a variety of potential damages. To the extent that these events occur, the total costs of the project could exceed our original estimates, and we could experience reduced profits or, in some cases, a loss for that project. Force majeure events could negatively impact our business, operations, revenues, cash flows and profits. Force majeure or extraordinary events beyond the control of the contracting parties, such as natural and man-made disasters, as well as terrorist actions, could negatively impact the economies in which we operate. We 23 typically negotiate contract language where we are allowed certain relief from force majeure events in private client contracts and review and attempt to mitigate force majeure events in both public and private client contracts. We remain obligated to perform our services after most extraordinary events subject to relief that may be available pursuant to a force majeure clause. If a contract contains a force majeure provision, we may be able to obtain an extension of time to complete our obligations under such contract, but we will still be subject to our other contractual obligations in the event of such an extraordinary event. Because we cannot predict the length, severity or location of any potential force majeure event, it is not possible to determine the specific effects any such event may have on us. Depending on the specific circumstances of any particular force majeure event, or if we are unable to react quickly to such an event, our operations may be affected significantly, our productivity may be affected, our ability to complete projects in accordance with our contractual obligations may be affected, our payments from customers may be delayed and we may incur increased labor and materials costs, which could have a negative impact on our financial condition, relationships with customers or suppliers, and our reputation. The amount of our estimated backlog may change and may not be indicative of future revenues. Our contract backlog represents our estimate of the revenues that we will realize under the portion of the contracts remaining to be performed. These estimates are based primarily upon the time and costs required to mobilize the necessary assets to and from the project site, the amount and type of material to be dredged and the expected production capabilities of the equipment performing the work. However, these estimates are necessarily subject to variances based upon actual circumstances. From time to time, changes in project scope may occur with respect to contracts reflected in our backlog and could reduce the dollar amount of our backlog and the timing of the revenue and profits that we actually earn. Projects may remain in our backlog for an extended period of time because of the nature of the project and the timing of the particular services or equipment required by the project. Because of these factors, as well as factors affecting the time required to complete each job, backlog is not necessarily indicative of future revenues or profitability. In addition, a significant amount of our backlog (62% as of December 31, 2021) relates to federal government contracts, which can be canceled at any time without penalty to the government, subject, in most cases, to our contractual right to recover our actual committed costs and profit on work performed up to the date of cancellation. Below is our backlog from federal government contracts as of December 31, 2021, 2020, and 2019 and the percentage of those contracts to total backlog as of the same date. Year Ended December 31, 2020 2021 2019 Federal government backlog (in US $1,000) Percentage of backlog from federal government $341,768 $390,345 $486,612 62% 70% 83% At times we may have backlog with foreign governments that use local laws and regulations to change terms of a contract in backlog or to limit our ability to receive payment on a timely basis. Other contracts in backlog are with state and local municipalities or private companies that may have funding constraints or impose restrictions on timing. The termination, modification or suspension of projects currently in backlog could have a material adverse effect on our business, operating results, cash flows or financial condition. Loss of a single customer contract could significantly decrease revenue. Prospective customers may be incentivized to use another dredging company other than the Company. The Company could lose future contracts for work to competitors or could be forced to accept lower margins on contracts. Lower utilization, workforce reductions or asset relocations could have a material adverse effect on our business, operating results, cash flows or financial condition. 24 While the Company does not currently have significant operations or equipment in the Middle East, we may seek contracts there in the future. Certain factors have occurred suggesting that future revenues from projects with governments in the Middle East could decrease. Historically lower oil prices and the contraction in Middle East commercial and real estate development have slowed the rate of the region’s infrastructure development. If the diplomatic relationship of the United States or our commercial relationship with governments in the Middle East is significantly negatively impacted or terminated, or we encounter significant difficulties in obtaining licensing or permits to do business in these countries, the Company’s international revenues would be materially and adversely impacted. If the government of Bahrain or Saudi Arabia further curtails its infrastructure investment or diversifies its use of dredging vendors, our revenue from these customers could decline further. Inability to obtain secure financing or financing on favorable terms for our new vessels. We have previously disclosed our plans to build new vessels which requires significant capital expenditures. Unforeseen issues could arise in our ability to obtain secure financing or to obtain secure financing on terms favorable to us for building such vessels. This includes our new offshore wind vessel and other potential future vessels. The inability to obtain favorable financing may also impact our ability to bring the new vessels into service within the timeline anticipated by the Company, which may have an adverse effect on our business, financial position and/or results of operations. Inability to secure contracts to utilize new offshore wind vessel. We have previously disclosed the build of our new offshore wind vessel that is in progress. Our ability to obtain customers and/or contracts on terms favorable to the Company to utilize this new vessel for subsea rock installation for wind turbines could be impacted by unforeseen market conditions. As the costs to build this new vessel have already been incurred, the lack of a secure customer base and favorable secure contracts could have a material adverse effect on the Company’s business, financial position and results of operations. Unforeseen delays and cost overruns could delay or halt plans to build new vessels and, as a result, negatively impact our business strategy. We have previously disclosed our plans to build new vessels. Unknown mechanical or engineering issues involving new vessels could adversely affect the Company’s business, operating results, cash flows or financial condition. Our future revenues and profitability will also be impacted to some extent by our ability to secure financing for new vessels and bring them into service within the timeline anticipated by the Company. The Company contracts with shipyards to build new vessels and currently has vessels under construction. Construction projects are subject to risks of delay and cost overruns, resulting from shortages of equipment, materials and skilled labor; lack of shipyard availability; unforeseen design and engineering problems; work stoppages; weather interference; unanticipated cost increases; unscheduled delays in the delivery of material and equipment; and financial and other difficulties at shipyards including labor disputes, shipyard insolvency and inability to obtain necessary certifications and approvals. A significant delay in the construction of new vessels or a shipyard’s inability to perform under the construction contract could negatively impact the Company’s ability to fulfill contract commitments and to realize timely revenues with respect to vessels under construction. Significant cost overruns or delays for vessels under construction could also adversely affect the Company’s business, operating results, cash flows or financial condition. Changes in governmental regulations, safety or other equipment standards, as well as compliance with standards imposed by maritime self-regulatory organizations and customer requirements or competition, could also substantially increase the cost of such construction beyond what we currently expect such costs to be. We have previously disclosed our plans to expand into the offshore wind market. Unknown changes to environmental needs and regulations and changes in the policies of the U.S. Presidential Administration could delay or halt plans to expand our new offshore wind projects, which would adversely impact our business strategy and affect the Company’s operating results, cash flows or financial condition. Our future revenues and 25 profitability will also be impacted to some extent if we are unable to obtain favorable steel prices or unable to obtain secure financing for new offshore wind vessels and bring them into service within the timeline anticipated by the Company. Our business would be adversely affected if we failed to comply with Jones Act provisions on coastwise trade, or if those provisions were modified or repealed. We are subject to the Jones Act and other federal laws that restrict dredging in U.S. waters and maritime transportation between points in the United States to vessels operating under the U.S. flag, built in the United States, at least 75% owned and operated by U.S. citizens and manned by U.S. crews. We are responsible for monitoring the ownership of our common stock to ensure compliance with these laws. If we do not comply with these restrictions, we would be prohibited from operating our vessels in the U.S. market, and under certain circumstances we would be deemed to have undertaken an unapproved foreign transfer, resulting in severe penalties, including permanent loss of U.S. dredging rights for our vessels, fines or forfeiture of the vessels. In the past, interest groups have unsuccessfully lobbied Congress to modify or repeal the Jones Act to facilitate foreign flag competition for trades and cargoes currently reserved for U.S. flag vessels under the Jones Act. We believe that continued efforts may be made to modify or repeal the Jones Act or other federal laws currently benefiting U.S. flag vessels. If these efforts are ever successful, it could result in significantly increased competition and have a material adverse effect on our business, results of operations, cash flows or financial condition. Our operating costs depend significantly on the price of petroleum-based products, and price increases could adversely affect our profits. Fuel prices fluctuate based on market events outside of our control. We use diesel fuel and other petroleum- based products to operate our equipment used in our dredging contracts. Fluctuations in supplies relative to demand and other factors can cause unanticipated increases in their cost. Most of our contracts do not allow us to adjust our pricing for higher fuel costs during a contract term and we may be unable to secure price increases reflecting rising costs when renewing or bidding contracts. In addition, the International Maritime Organization issued regulations regarding use of low sulfur fuel, which has increased the demand for low sulfur fuel. We use low sulfur fuel in many of our domestic operations, and future increases in the costs of fuel and other petroleum- based products used in our business, particularly if a bid has been submitted for a contract and the costs of those products have been estimated at amounts less than the actual costs thereof, could result in a lower profit, or even a loss, on one or more contracts. Our investing and operating costs depend significantly on the prices of new build materials, and price increases due to high nationwide inflation could adversely affect our profits. The prices of steel and other materials to build and develop new vessels fluctuate based on market events outside of our control. Most of our contracts do not allow us to adjust our pricing for higher material costs during a contract term. When renewing contracts, we may be unable to secure price increases reflecting the rising costs of inflation. Such future increases in the costs of steel and other materials used to build new vessels, particularly if a bid or renewal has been submitted for a contract and the costs of the required products have been estimated at amounts less than the actual costs incurred, could result in a lower profit, or even a loss, on one or more contracts. 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. We are generally required to post bonds in connection with our domestic dredging contracts and bonds or letters of credit with our foreign dredging contracts to ensure job completion if we ever fail to finish a project. 26 We have entered into bonding agreements with the sureties, or the “Sureties”, pursuant to which the Sureties issue bid bonds, performance bonds and payment bonds, and provide guarantees required by us in the day-to-day operations of our dredging business. The Company also has outstanding bonds with Travelers Casualty and Surety Company of America and Zurich. Historically, we have had a strong bonding capacity, but surety companies issue bonds on a project-by-project basis and can decline to issue bonds at any time or require the posting of collateral as a condition to issuing any bonds. With respect to our foreign dredging business, we generally obtain letters of credit under our Amended Credit Agreement. However, access to our senior credit facility under our Amended Credit Agreement may be limited by failure to meet certain levels of availability or other defined financial or other requirements. If we are unable to obtain bonds or letters of credit on terms reasonably acceptable to us, our ability to take on future work would be severely limited. In connection with the sale of our historical demolition business, we were obligated to keep in place the surety bonds on pending demolition projects for the period required under the respective contract for a project. In 2017, we were notified by Zurich of an alleged default triggered on a historical demolition surety performance bond in the aggregate amount of approximately $20 million for failure of the contractor to perform in accordance with the terms of a project. Zurich drew upon the letter of credit in the amount of $20.9 million. In order to fund the draw on the letter of credit, we had to increase the borrowings on our revolving credit facility. As the outstanding letters of credit previously reduced our availability under the revolving credit facility, this draw down on our letter of credit did not impact our liquidity or capital availability. However, in the future, other defaults (or alleged defaults) triggered under any of our surety bonds could have a material adverse effect on our business, results of operations, cash flows or 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. We may seek business acquisition activities as a means of broadening our offerings and capturing additional market opportunities by our business units. We may be exposed to certain additional risks resulting from these activities. Acquisitions may expose us to operational challenges and risks, including: • • • • • • • • • • • • the effects of valuation methodologies which may not accurately capture the value proposition; the failure to integrate acquired businesses into our operations, financial reporting and controls with the efficiency and effectiveness initially expected resulting in a potentially significant detriment to our financial results and our operations as a whole; the management of the growth resulting from acquisition activities; the inability to capitalize on expected synergies; the assumption of liabilities of an acquired business (for example, litigation, tax liabilities, environmental liabilities), including liabilities that were contingent or unknown at the time of the acquisition and that pose future risks to our working capital needs, cash flows and the profitability of related operations; the assumption of unprofitable projects that pose future risks to our working capital needs, cash flows and the profitability of related operations; the risks associated with entering new markets; diversion of management’s attention from our existing business; failure to retain key personnel, customers or contracts of any acquired business; potential adverse effects on our ability to comply with covenants in our existing debt financing; potential impairment of acquired intangible assets; and additional debt financing, which may not be available on attractive terms. 27 We may not have the appropriate management, financial or other resources needed to integrate any businesses that we acquire. Any future acquisitions may result in significant transaction expenses and unexpected liabilities. Divestitures and discontinued operations could negatively impact our business, and any retained liabilities could adversely affect our financial results. As part of our strategic process, we review our operations for assets and businesses which may no longer be aligned with our strategic initiatives and long-term objectives. For example, we have divested our historical environmental & infrastructure business and historical demolition business. We continue to review our assets and strategy and may pursue additional divestitures. Divestitures pose risks and challenges that could negatively impact our business, including required separation or carve-out activities and costs, disputes with buyers or potential impairment charges. We may also dispose of a business at a price or on terms that are less than we had previously anticipated or fail to close a transaction at all. Dispositions may also involve continued financial involvement, as we may be required to retain responsibility for, or agree to indemnify buyers against contingent liabilities related to businesses sold, such as lawsuits, surety obligations, tax liabilities, or environmental matters. It may also be difficult to determine whether a claim from a third party stemmed from actions taken by us or by another party and we may expend substantial resources trying to determine which party has responsibility for the claim. Under these types of arrangements, performance by the divested businesses or other conditions outside of our control could affect future financial results and such claims or conditions may divert management attention from our continuing business. During the second quarter of 2014, the Company completed the sale of its historical demolition business. In connection with the sale, the Company retained responsibility for various pre-closing liabilities and obligations and may incur costs and expenses related to these items and asset recoveries. It is possible that claims, which could be material, could be made against the Company by virtue of the agreement pursuant to which the Company’s historical demolition business was sold. In connection with the sale of our historical demolition business, we were obligated to keep in place the surety bonds on pending demolition projects for the period required under the respective contract for a project. As noted above, if there should be a default (or alleged default) triggered under any of the surety bonds for the historical demolition business, it could have a material adverse effect on our ability to obtain bonds and on our business, results of operations, cash flows or financial condition. During the second quarter of 2019, the Company completed the sale of the historical environmental & infrastructure business. The Company retained responsibility for pre-closing liabilities and indemnification for breaches of our representations and warranties in the sale agreement. If the buyer made a claim against any of our indemnifications or if any payments became due in connection with any pre-closing liability, they could be material to results of operations, cash flows or financial condition. If we do not realize the expected benefits or synergies of any divestiture transaction or if we underestimated the valuation of the charge related to placing an asset held for sale in discontinued operations, our consolidated financial position, results of operations and cash flows could be negatively impacted. Any divestiture may result in a dilutive impact to our future earnings if we are unable to offset the dilutive impact from the loss of revenue associated with the divestiture, as well as significant write-offs, including those related to goodwill and other intangible assets, which could have a material adverse effect on our results of operations and financial condition. We could face liabilities and/or damage to our reputation as a result of certain legal and regulatory proceedings, including a pending legal proceeding in Louisiana. We operate in a highly regulated environment with constantly evolving legal and regulatory frameworks. From time to time, we are subject to legal and regulatory proceedings in the ordinary course of our business. These include proceedings relating to aspects of our businesses that are specific to us and proceedings that are typical in the businesses in which we operate. 28 In particular, on April 22, 2021, the U.S. Attorney’s Office for the Eastern District of Louisiana filed a bill of information against the Company charging the Company with a negligent discharge violation of the Clean Water Act arising from a September 2016 oil spill. The spill occurred during the Company’s Cheniere Ronquille project and resulted in the discharge of around one hundred sixty barrels of crude oil in Bay Long, Louisiana. The Company has cooperated with the U.S. Attorney’s Office and other relevant agencies in their investigation of the oil spill and on June 15, 2021, the Company pleaded guilty to the misdemeanor violation alleged in the bill of information and agreed to pay a fine of $1 million. In the first quarter of 2022, the Company entered into a settlement of a civil suit arising from the same matter. The Company remains subject to potential liability for restitution in connection with this criminal matter, and has deposited the potential liability for the criminal matter of $2 million into the registry of the court. That amount is presented as restricted cash in other noncurrent assets. As a result of the pending conviction, the government will likely initiate statutory debarment proceedings against us, which might prohibit us from bidding for, entering into or completing certain government projects. Although the Company does not know whether debarment proceedings will result in prohibitions, or the impact of any such resulting prohibitions, the Company does not expect any such proceedings or prohibitions to cause a material disruption to its business, financial condition or results of operations. We are also currently a defendant in a number of other litigation matters, including those described in Item 3. “Legal Proceedings” of this Annual Report on Form 10-K. In certain of these matters, the plaintiffs are seeking large and/or indeterminate amounts of damages. These matters are also subject to many uncertainties, and it is possible that some of these matters could ultimately be decided, resolved or settled adversely to the Company. An adverse outcome in a legal or regulatory matter could, depending on the facts, have an adverse effect on our business, results of operations, cash flows or financial condition. Furthermore, whether the ultimate outcomes are favorable or unfavorable, these matters can also have significant adverse reputational impacts, including negative publicity and press speculation about us, whether valid or not, which may be damaging to our business, results of operations, cash flows or financial condition. Liabilities for the obligations of our joint ventures, partners and subcontractors could materially decrease our profitability and liquidity. Some of our projects are performed through joint ventures and similar arrangements with other parties. In addition to the usual liability of contractors for the completion of contracts and the warranty of our work, if work is performed through a joint venture or similar arrangement, we also have potential liability for the work performed by the joint venture or arrangement or a performance or payment default by another member of the joint venture or arrangement. In these projects, even if we satisfactorily complete our project responsibilities within budget, we may incur additional unforeseen costs due to the failure of the other party or parties to the arrangement to perform or complete work, fund expenditures, or make payments in accordance with contract specifications. In some joint ventures and similar arrangements, we may not be the controlling member. In these cases, we may have limited control over the actions of the joint venture. In addition, joint ventures or arrangements may not be subject to the same requirements regarding internal controls and internal control over financial reporting that we follow. To the extent the controlling member makes decisions that negatively impact the joint venture or arrangement or internal control problems arise within the joint venture or arrangement, it could have a material adverse impact on our business, results of operations, cash flows or financial condition. Depending on the nature of work required to complete the project, we may choose to subcontract a portion of the project. In our industries, the prime contractor is often responsible for the performance of the entire contract, including subcontract work. Thus, we are subject to risks associated with the failure of one or more subcontractors to perform as anticipated. In addition, in some cases, we pay our subcontractors before our customers pay us for the related services. If we choose, or are required, to pay our subcontractors for work performed for customers who fail to pay, or delay paying us for the related work, we could experience a material decrease in profitability and liquidity. 29 New tariffs have increased our costs and could adversely affect our business operations, revenues and profits. In recent years, the United States has imposed Section 232 tariffs and other import taxes on certain steel and aluminum products, such as imported dredge-related machinery and pipes. These tariffs and other import taxes have increased the prices of these inputs. Increased prices for imported steel and aluminum products have led domestic sellers to respond with market-based increases to prices for such inputs as well. We cannot be sure of the ultimate effect such tariffs or any additional import taxes will have on our operating profits. If we are not able to pass these price increases on to our customers or to secure adequate alternative sources for such inputs on a timely basis, the tariffs and other import taxes may have a material adverse effect on our business operations, revenues and profits. Our business could suffer in the event of a work stoppage by our unionized labor force. We are a party to numerous collective bargaining agreements in the U.S. that govern our industry’s relationships with our unionized hourly workforce. Two unions represent approximately 74% of our hourly dredging employees—the IUOE Local 25 and the Seafarers International Union. The Company’s master and ancillary contracts with IUOE Local 25 expire in September 2024. The Company’s master contract with Seafarers International Union expires in February 2023. The inability to successfully renegotiate contracts with these unions as they expire, or any future strikes, employee slowdowns or similar actions by one or more unions could have a material adverse effect on our ability to operate our business. Liabilities imposed by federal laws for job-related claims by seagoing employees could increase our costs and reduce our profitability. Substantially all of our maritime employees are covered by provisions of the Jones Act, the U.S. Longshore and Harbor Workers’ Compensation Act, the Seaman’s Wage Act and general maritime law. These laws typically operate to make liability limits established by state workers’ compensation laws inapplicable to these employees and to permit these employees and their representatives to pursue actions against employers for job-related injuries in federal or state courts. Because we are not generally protected by the limits imposed by state workers’ compensation statutes with respect to our seagoing employees, we have greater exposure for claims made by these employees as compared to industries whose employees are not covered by these provisions. Successful claims could materially 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. The dredging business is generally subject to a number of risks and hazards, including environmental hazards, industrial accidents, encountering unusual or unexpected geological formations, cave-ins below water levels, collisions, disruption of transportation services, flooding and unexploded ordnance. These risks could result in personal injury, damage to, or destruction of, dredges, barges transportation vessels, other maritime vessels, other structures, buildings or equipment, environmental damage, performance delays, monetary losses or legal liability to third parties. We may also be exposed to disruption of our operations, early termination of projects, unanticipated recovery costs and loss of use of our equipment that may materially adversely affect our business, results of operations, cash flows or financial condition. Our safety record is an important consideration for our customers. Some of our customers require that we maintain certain specified safety record guidelines to be eligible to bid for contracts with these customers. Furthermore, contract terms may provide for automatic termination or forfeiture of some of our contract revenue in the event that our safety record fails to adhere to agreed-upon guidelines during performance of the contract. As a result, if serious accidents or fatalities occur or our safety record were to deteriorate, we may be ineligible to bid on certain work, and existing contracts could be terminated or less profitable than expected. Adverse experience with hazards and claims could have a negative effect on our reputation with our existing or potential new customers and our prospects for future work. 30 We may be unable to identify and contract with qualified MBE or DBE contractors to perform as subcontractors, which could materially and adversely impact our financial position, results of operations, cash flows and liquidity. Certain of our government agency projects contain goals for minimum minority business enterprise (“MBE”) and/or disadvantaged business enterprise (“DBE”) participation clauses. If we subsequently fail to reach our goals for the minimum MBE and/or DBE participation, we may be held responsible for breach of contract, which may include restrictions on our ability to bid on future projects as well as monetary damages. To the extent we are responsible for monetary damages, the total costs of the project could exceed our original estimates, we could experience reduced profits or a loss for that project and there could be a material adverse impact to our financial position, results of operations, cash flows and liquidity. Risks Related to our Financing We have substantial indebtedness, which makes us more vulnerable to adverse economic and competitive conditions. We currently have a substantial amount of indebtedness. As of December 31, 2021, we had indebtedness of $325.0 million, consisting of our senior subordinated notes. Currently, we have no borrowings on our revolving credit facility and approximately $25.1 million of undrawn letters of credit, leaving $174.5 million of additional borrowing capacity under our revolving credit facility. These figures exclude contingent obligations, including $1.2 billion of performance bonds outstanding under the Company’s agreements with the Sureties and other bonding agreements. Our level of indebtedness could: • • • • • require us to dedicate a portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital and capital expenditures, pay dividends and other general corporate purposes; limit our flexibility in planning for, or reacting to, changes in our business and our industries; affect our competitiveness compared to our less leveraged competitors; increase our exposure to both general and industry-specific adverse economic conditions; and limit, among other things, our ability to borrow additional funds. We and our subsidiaries also may be able to incur substantial additional indebtedness in the future. The terms of our revolving credit facility and the indenture under which our senior subordinated notes are issued limit, but do not prohibit, us or our subsidiaries from incurring additional indebtedness. If new indebtedness is added to our current debt levels, the related risks that we and our subsidiaries now face could intensify. Covenants in our financing arrangements limit, and other future financing agreements may limit, our ability to operate our business. The credit agreement governing our senior revolving credit facility and the indenture governing our senior notes contain, and any of our other future financing agreements may contain covenants imposing operating and financial restrictions on our business. For example, the credit agreement governing our senior revolving credit facility requires us to satisfy a fixed charge coverage ratio under certain circumstances. If we fail to satisfy such covenant, we would be in default and the lenders (through the administrative agent or collateral agent, as applicable) could elect to declare all amounts outstanding to be immediately due and payable, enforce their interests in the collateral pledged and/or restrict our ability to make additional borrowings, as applicable. The covenants in the credit agreement governing our senior revolving credit facility and the indenture governing our senior notes, subject to specified exceptions and to varying degrees, restrict our ability to, among other things: • incur additional indebtedness; 31 • • • create, incur, assume or permit to exist any liens; enter into sale and leaseback transactions; enter into operating leases; • make investments, loans and advancements; • merge, consolidate or reorganize with, or dispose of all or substantially all assets to, a third party; • sell assets; • make acquisitions; • • • • pay dividends; enter into transactions with affiliates; prepay or redeem other indebtedness; and issue certain types of capital stock. These restrictions may interfere with our ability to obtain financings or to engage in other business activities, which could have a material adverse effect on our results of operations, cash flows or financial condition. Adverse capital and credit market conditions may affect our ability to access capital and meet liquidity needs. The domestic and worldwide capital and credit markets may experience significant volatility, disruptions and dislocations with respect to price and credit availability. Should we need additional funds or to refinance our existing indebtedness, we may not be able to obtain such additional funds or refinancing on acceptable terms, or at all. We need liquidity to pay our operating expenses, interest on our debt and dividends on our capital stock. Without sufficient liquidity, we will be forced to curtail our operations, and our business will suffer. The principal sources of our liquidity are cash flow from operations and borrowings under our senior revolving credit facility. Earnings from our operations and our working capital requirements can vary significantly from period to period based primarily on the mix of our projects underway and the percentage of project work completed during the period. Capital expenditures may also vary significantly from period to period. While we manage cash requirements for working capital and capital expenditure needs, unpredictability in cash collections and payments has required us in the past and may in the future require us to borrow on our line of credit from time to time to meet the needs of our operations. In the event these resources do not satisfy our liquidity needs, we may have to seek additional financing. The availability of additional financing will depend on a variety of factors such as market conditions, the general availability of credit, the volume of trading activities, our credit ratings and credit capacity, as well as the possibility that customers or lenders could develop a negative perception of our long- or short-term financial prospects if the level of our business activity decreased due to a market downturn. If internal sources of liquidity prove to be insufficient, we may not be able to successfully obtain additional financing on favorable terms, or at all. We may be unable to maintain or expand our credit capacity, which would adversely affect our operations and business. We use credit facilities to support our working capital and acquisition needs. If we exhaust our borrowing capacity under our Amended Credit Agreement, and cash flows from operations do not increase sufficiently, our ability to fund the working capital, capital expenditure and other needs of our existing operations could be 32 constrained and our business and results of operations could be materially adversely affected. If we experience operational difficulties or our operating results do not improve, we may need to increase our available borrowing capacity or seek amendments to the terms of our Amended Credit Agreement. Our Amended Credit Agreement is scheduled to expire on May 3, 2024. We strive to enter into new arrangements on terms that are more favorable than the terms of the Amended Credit Agreement, but we cannot guarantee that we will be able to obtain financing on commercially reasonable terms or at all, or alternatively that we will be able to secure any additional capacity or amend our Amended Credit Agreement or do so on terms that are acceptable to us, in which case, our costs of borrowing could rise and our business and results of operations could be materially adversely affected. Regulatory requirements for derivative transactions could adversely impact our ability to hedge interest rate, currency or commodity risks. We may enter into interest rate swap agreements to manage the interest rate paid with respect to our fixed rate indebtedness, foreign exchange forward contracts to hedge currency risk and heating oil commodity swap contracts to hedge the risk that fluctuations in diesel fuel prices will have an adverse impact on cash flows associated with our domestic dredging contracts. The Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”) and regulations adopted by a number of U.S. federal regulatory agencies created a comprehensive statutory and regulatory framework for derivative transactions, including foreign currency and other over-the-counter derivative hedging transactions. While a number of provisions of Dodd-Frank have been implemented, certain key provisions have not yet been implemented or remain subject to uncertainty. Furthermore, certain provisions of Dodd-Frank may be modified or repealed in the future. Any substantial change in the financial regulatory environment could create additional new compliance costs for us or cause us to alter the manner in which we manage risk, which could have a materially adverse effect on our business. The rules adopted or to be adopted under Dodd-Frank may significantly reduce our ability to execute strategic hedges to manage our interest expense, reduce our fuel commodity uncertainty and hedge our currency risk thus protecting our cash flows. In addition, the banks and other derivatives dealers who are our contractual counterparties are required to comply with extensive regulation under Dodd-Frank. The cost of our counterparties’ compliance will likely be passed on to customers such as ourselves, thus potentially decreasing the benefits to us of hedging transactions and potentially reducing our profitability. We may be subject to foreign exchange risks, which could result in large cash losses. We are exposed to market risk associated with changes in foreign currency exchange rates. The primary foreign currencies to which the Company has exposure are the Euro, Korean Won and Bahraini dinar. We have unhedged foreign currency exposure related to the new inclined fall-pipe vessel for subsea rock installation build, in particular, as it relates to the procurement of steel for this build. Our international contracts may be denominated in foreign currencies, which will result in additional risk of fluctuating currency values and exchange rates, hard currency shortages and controls on currency exchange. Changes in the value of foreign currencies could increase our U.S. dollar costs for, or reduce our U.S. dollar revenues from, our foreign operations. Any increased costs or reduced revenues as a result of foreign currency fluctuations could affect our profits. Our investments in, and extensions of payment terms for, privately financed projects could result in significant losses. We have participated and may continue to participate in privately financed projects that enable state and local governments and other customers to finance dredging, such as dredging of local navigable waterways and lakes, coastal protection and infrastructure projects. These projects typically include the facilitation of non-recourse financing and the provision of dredging, environmental, infrastructure, and related services. We may incur contractually reimbursable costs and may accept extended payment terms, extend debt financing and/or make an equity investment in an entity prior to, in connection with, or as part of project financing, and in some cases we may be the sole or primary source of the project financing. Project financing may also involve the use of real estate, environmental, wetlands or similar credits. If a project is unable to obtain other financing on terms acceptable to it 33 in amounts sufficient to repay or redeem our investments, we could incur losses on our investments and any related contractual receivables. After completion of these projects, the return on our equity investments can be dependent on the operational success of the project and market factors or sale of the aforementioned credits, which may not be under our control. As a result, we could sustain a loss of part or all of our equity investments in such projects or have to recognize the value of the credits at a lower amount than expected in the contract bid. Risks Related to our Stock Our common stock is subject to restrictions on foreign ownership. We are subject to government regulations pursuant to the Dredging Act, the Jones Act, the Shipping Act and the vessel documentation laws set forth in Chapter 121 of Title 46 of the United States Code. These statutes require vessels engaged in the transport of merchandise or passengers or dredging in the navigable waters of the U.S. to be owned and controlled by U.S. citizens. The U.S. citizenship ownership and control standards require the vessel- owning entity to be at least 75% U.S.-citizen owned. Our certificate of incorporation contains provisions limiting non-citizenship ownership of our capital stock. If our board of directors determines that persons who are not citizens of the U.S. own more than 22.5% of our outstanding capital stock or more than 22.5% of our voting power, we may redeem such stock. The required redemption price could be materially different from the current price of our common stock or the price at which the non-citizen acquired the common stock. If a non-citizen purchases our common stock, there can be no assurance that they will not be required to divest the shares and such divestiture could result in a material loss. Such restrictions and redemption rights may make our equity securities less attractive to potential investors, which may result in our common stock having a lower market price than it might have in the absence of such restrictions and redemption rights. Delaware law and our charter documents may impede or discourage a takeover that our stockholders may consider favorable. The provisions of our certificate of incorporation and bylaws may deter, delay or prevent a third-party from acquiring us. These provisions include: • • • • • limitations on the ability of stockholders to amend our charter documents, including stockholder supermajority voting requirements; the inability of stockholders to call special meetings; a classified board of directors with staggered three-year terms; advance notice requirements for nominations for election to the board of directors and for stockholder proposals; and the authority of our board of directors to issue, without stockholder approval, up to 1,000,000 shares of preferred stock with such terms as the board of directors may determine and to issue additional shares of our common stock. We are also subject to the protections of Section 203 of the Delaware General Corporation Law, which prevents us from engaging in a business combination with a person who acquires at least 15% of our common stock for a period of three years from the date such person acquired such common stock, unless board or stockholder approval was obtained. These provisions could have the effect of delaying, deferring or preventing a change in control of our company, discourage others from making tender offers for our shares, lower the market price of our stock or impede the ability of our stockholders to change our management, even if such changes would be beneficial to our stockholders. 34 Our stockholders may not receive dividends because of restrictions in our debt agreements or Delaware law. Our ability to pay dividends is restricted by the agreements governing our debt, including our Amended Credit Agreement, our bonding agreements and the indenture governing our senior unsecured notes. In addition, under Delaware law, our board of directors may not authorize payment of a dividend unless it is either paid out of our surplus, as calculated in accordance with the Delaware General Corporation Law, or, if we do not have a surplus, it is paid out of our net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. To the extent we do not have adequate surplus or net profits, we will be prohibited from paying dividends. Significant fluctuations in the market price of our common stock may affect the ability of holders to resell our common stock at prices that they find attractive. The price of our common stock on the NASDAQ Global Market constantly changes. We expect that the market price of our common stock will continue to fluctuate. The market price of our common stock may fluctuate as a result of a variety of factors, many of which are beyond our control. These factors include: • • • • • • • • • • • changes in market conditions; quarterly variations in our operating results; operating results that vary from the expectations of management, securities analysts and investors; changes in expectations as to our future financial performance; announcements of strategic developments, significant contracts, acquisitions and other material events by us or our competitors; the operating and securities price performance of other companies that investors believe are comparable to us; future sales of our equity or equity-related securities; changes in the economy and the financial markets; departures of key personnel; changes in governmental regulations; and geopolitical conditions, such as acts or threats of terrorism, political instability, civil unrest or military conflicts. In addition, in recent years, global stock markets have experienced extreme price and volume fluctuations. This volatility has had a significant effect on the market price of securities issued by many companies for reasons often unrelated to their operating performance. These broad market fluctuations may adversely affect the market price of our common stock, regardless of our operating results. Volatility in the financial markets could cause a decline in our stock price, which could trigger an impairment of the goodwill of individual reporting units that could be material to our consolidated financial statements. A significant drop in the price of our stock could also expose us to the risk of securities class action lawsuits, which could result in substantial costs and divert management’s attention and resources, which could adversely affect our business. Additionally, volatility or a lack of positive performance in our stock price may adversely affect our ability to retain key employees, many of whom are awarded equity securities, the value of which is dependent on the performance of our stock price. 35 General Risk Factors Our methods of accounting for recognizing revenue involve significant estimates and could result in a change in previously recorded revenue and profit. We recognize revenue on our projects using generally accepted accounting principles in the United States (“GAAP”) including guidance from Revenue from Contracts with Customers, as amended (commonly referred to as ASC 606) subsequent to year-end December 31, 2017. The majority of our work is performed on a fixed-price basis. Contract revenue is recorded over time based on estimates which we develop from information known to us at the time of recording, but which may change. The cumulative impact of revisions to estimates is reflected in the period in which these changes are experienced or become known. Given the risks associated with the variables in these types of estimates, it is possible for actual costs to vary from estimates previously made, which may result in reductions or reversals of previously recorded net revenues and profits. Our current insurance coverage may not be adequate, and we may not be able to obtain insurance at acceptable rates, or at all. We maintain various insurance policies, including hull and machinery, pollution liability, general liability and personal injury. We partially self-insure risks covered by our policies. While we reserve for such self-insured exposures when appropriate for accounting purposes, we are not required to, and do not, specifically set aside funds for the self-insured portion of claims. We may not have insurance coverage or sufficient insurance coverage for all exposures potentially arising from a project. Furthermore, in situations where there is insurance coverage, if multiple policies are involved, we may be subject to a number of self-retention or deductible amounts which in the aggregate could have an adverse effect on our business, results of operations, cash flows or financial condition. At any given time, we are subject to Jones Act personal injury claims and claims from general contractors and other third parties for personal injuries. Our insurance policies may not be adequate to protect us from liabilities that we incur in our business. We may not be able to obtain similar levels of insurance on reasonable terms, or at all. Our inability to obtain such insurance coverage at acceptable rates or at all could have a material adverse effect on our business, results of operations, cash flows or financial condition. 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. Our ability to attract and retain reliable, qualified personnel is a significant factor that enables us to successfully bid for and profitably complete our work. This includes members of our board of directors, management, project managers, estimators, skilled engineers, supervisors, foremen, equipment operators and laborers. The loss of the services of any of our management could have a material adverse effect on us. If we do not succeed in retaining our current key employees and attracting, developing and retaining new highly-skilled employees, our reputation may be harmed and our operations and future earnings may be negatively impacted. We may not be able to maintain an adequate skilled labor force necessary to operate efficiently and to support our growth strategy. We have from time to time experienced, and may in the future experience, shortages of certain types of qualified equipment operating personnel. We have experienced, and may continue to experience, some difficulty finding skilled labor in the current labor shortage market. The supply of experienced engineers, project managers, field supervisors and other skilled workers may not be sufficient to meet current or expected demand. If we are unable to hire employees with the requisite skills, we may also be forced to incur significant training expenses. The occurrence of any of the foregoing could have an adverse effect on our business, results of operations, cash flows or financial condition. In addition, any abrupt changes in our management or board of directors may lead to concerns regarding the direction or stability of our business, which may be exploited by our competitors, result in the loss of business opportunities, cause concern to our current or potential customers or suppliers, or make it more difficult to retain existing personnel or attract and retain new personnel. Changes in management or the board could be time- 36 consuming, result in significant additional costs to us and could be disruptive of our operations and divert the time and attention of management and our employees away from our business operations and executing on our strategic plan. The unexpected loss of members of our board of directors or senior management team could be disruptive to our operations, jeopardize our ability to raise additional funding and have an adverse effect on our business. The failure of our directors or any new members of our board of directors or management to perform effectively could have a significant negative impact on our business, financial condition and results of operations. Disruption, failure, data corruption, cyber-based attacks or security breaches of our IT systems could adversely affect our business and results of operations. We rely on information technology (“IT”) systems in order to achieve our business objectives, including to transmit and store electronic information, to capture knowledge of our business including vessel operation systems containing information about production, efficiency and vessel positioning, to conduct our accounting, financial and treasury activities, to store historical financial, project and proprietary information, to monitor our vessel maintenance and engine systems, and to communicate within the organization and with customers, suppliers, partners and other third parties. Our portfolio of hardware and software products, solutions and services and our enterprise IT systems may be vulnerable to damage or disruption caused by circumstances beyond our control such as catastrophic events, power outages, natural disasters and computer system or network failures. The Company’s IT systems may also be subject to cybersecurity attacks including malware, other computer viruses or malicious software, spoofing or phishing email attacks, attempts to gain unauthorized access to our data, the unauthorized release, corruption or loss of its data, loss or damage to its data delivery systems and other electronic security breaches. The failure or disruption of our IT systems to perform as anticipated for any reason could disrupt our business and result in decreased performance, significant remediation costs, transaction errors, loss of data, processing inefficiencies, downtime, failure to properly estimate the work or costs associated with projects, litigation and the loss of customers or suppliers. A significant disruption or failure could have a material adverse effect on our business, operating results, cash flows or financial condition. Impairments to our goodwill or other intangible assets could negatively affect our financial condition and results of operations. Under current accounting guidelines, we must assess, at least annually and potentially more frequently, whether the value of our goodwill and other intangible assets have been impaired. Any impairment of goodwill or other intangible assets as a result of such analysis would result in a non-cash charge against earnings, which charge could materially adversely affect our business, operating results or financial condition. We test goodwill annually for impairment in the third quarter of each year, or more frequently should circumstances dictate. A significant and sustained decline in our future cash flows, a significant adverse change in the economic environment, slower growth rates or our stock price falling below our net book value per share for a sustained period could result in the need to perform additional impairment analysis in future periods. If we were to conclude that a future write-down of goodwill or other intangible assets is necessary, then we would be required to record a non-cash charge against earnings, which, in turn, could have a material adverse effect on our business, results of operations or financial condition.

Accordingly, the Company cannot ensure the size of any such dividend or that the Company will pay any future dividend. Item 6. Selected Financial Data Not applicable. 40 Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Overview Great Lakes is the largest provider of dredging services in the United States. In addition, the Company has a long history of performing significant international projects. The Company operates in one reportable segment. Dredging generally involves the enhancement or preservation of the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Domestically, our work generally is performed in coastal waterways and deep water ports. The U.S. dredging market consists of four primary types of work: capital, coastal protection, maintenance and rivers & lakes. Capital dredging consists primarily of port expansion projects, which involve the deepening of channels and berthing basins to allow access by larger, deeper draft ships and the provision of land fill used to expand port facilities. In addition to port work, capital projects also include coastal restoration and land reclamations, trench digging for pipelines, tunnels, and cables and other dredging related to the construction of breakwaters, jetties, canals and other marine structures. Coastal protection projects generally involve moving sand from the ocean floor to shoreline locations where erosion threatens shoreline assets. Maintenance dredging consists of the re-dredging of previously deepened waterways and harbors to remove silt, sand and other accumulated sediments. Due to natural sedimentation, most channels generally require maintenance dredging every one to three years, thus creating a recurring source of dredging work that is typically non-deferrable if optimal commercial navigability is to be maintained. In addition, severe weather such as hurricanes, flooding and droughts can also cause the accumulation of sediments or severe erosion and drive the need for maintenance and coastal protection dredging. Rivers & lakes dredging and related operations typically consist of lake and river dredging, flood control dredging, inland levee and construction dredging, environmental restoration and habitat improvement and other marine construction projects. The Company’s fleet, which includes 18 dredges, 17 material transportation barges, one drillboat, and numerous other support vessels, is the largest and most diverse fleet of any U.S. dredging company. Our fleet of dredging equipment can be utilized on one or many types of work and in various geographic locations. This flexible approach to our fleet utilization, driven by the project scope and equipment, enables us to move equipment in response to changes in demand for dredging services to take advantage of the most attractive opportunities. The coronavirus (“COVID-19”) pandemic has severely impacted global economic activity and many countries, including the United States and its governmental entities and private businesses, have reacted by instituting quarantines, mandating school and business closures and limiting travel at various times throughout the pandemic. On March 28, 2020, dredging was specifically listed in the U.S. Department of Homeland Security’s “Advisory Memorandum on Identification of Essential Critical Infrastructure Workers During COVID-19 Response” which federally designates the Company as an essential business or “critical infrastructure” company that can maintain operations during the ongoing pandemic. The Company’s largest domestic dredging customer is the Corps; the Corps oversees the majority of these critical infrastructure projects and, in this capacity, has continued to follow their bid schedule and prioritize all types of dredging including port maintenance and expansion and coastal protection projects that are necessary to avoid potential storm damage during hurricane season. Despite the uncertainty surrounding COVID-19, to date, the Corps is continuing to advertise new projects. Our Executive Leadership team has established a COVID-19 Command Team that meets once each week to update contingency plans, as necessary, and address the challenges related to maintaining operations in this evolving economic environment. The Company’s primary focus has been the health and safety of its employees. The Company has implemented new paid leave policies and additional sanitary and safety measures to mitigate the risk of infection to employees. On vessels and job sites, the Company has instituted fewer employee shift changes and increased sanitary and social distancing measures. During the first half of 2021, the Company began 41 to experience increased project costs and delays related to COVID-19 as several vessel crews were infected despite extensive testing and isolation protocols. Vessels were required to go to shore for crew changes and the vessels had to be disinfected before returning to work. This impacted the vessels’ scheduling and availability which led to project delays. The Company is now 100% fully vaccinated against COVID-19, with few accommodations. Direct COVID-19 related costs were approximately $9.9 million for the year with nearly the same amount for indirect COVID-19 costs for the year. These costs decreased in the second half of the year as compared to the first half of 2021. Mid 2021, the Company’s corporate employees began transitioning from a remote working environment to working in person with a hybrid working environment. The Company is following the protocols published by the U.S. Centers for Disease Control and Prevention, the World Health Organization and state and local governments. As the Company’s employees, customers and communities are facing significant challenges, the Company cannot predict how COVID-19 will evolve or the impact it, or actions taken to contain it, will have on future results. Due to the uncertainty that surrounds this virus, the Company will be continually evaluating safety and operational contingency plans and the potential future impact that this evolving environment has on the Company’s business, financial condition and results of operations. In 2020, the U.S. government enacted the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) and other legislation which contain tax incentives designed to help businesses deal with the current economic turmoil caused by the pandemic. The coronavirus relief tax acts provide emergency economic stimulus which, among other things, includes various tax provisions relating to refundable payroll tax credits, deferment of the employer side of certain payroll taxes and social security payments, net operating loss carryback periods, alternative minimum tax credit refunds and modifications to the net interest deduction limitations. The Company elected to defer the employer side of certain payroll taxes and paid the first portion of these taxes in 2021 and will pay the remainder in 2022. In 2020, the Company announced the relocation of its headquarters from Illinois to Houston, Texas, and the new Houston corporate office opened in the first quarter of 2021. The relocation places the Company closer to key regional customers and new markets, especially along the Gulf Coast and the Mississippi River. The Company plans to participate in the offshore wind market, and in November 2021, the Company entered into a $197 million contract with Philly Shipyard to build the first U.S. flagged Jones Act compliant, inclined fall-pipe vessel for subsea rock installation for wind turbine foundations with expected delivery of the vessel in the second half of 2024. This vessel represents a significant critical advancement in building the U.S. logistics infrastructure to support the future of the new U.S. offshore wind industry. The Company has begun bidding on select projects in the offshore wind market. The current Presidential Administration has pushed to accelerate renewable energy developments and has set a target to install 30GW of offshore wind energy generation capacity by 2030 on the U.S. East Coast. In March 2021, the White House announced new initiatives that will advance the Presidential Administration’s goals to expand the nation’s offshore wind energy capacity in the coming decade by opening new areas of development, improving environmental permitting and increasing public financing for projects. The Company’s bid market is defined as the aggregate dollar value of domestic dredging projects on which we bid or could have bid if not for capacity constraints or other considerations (“bid market”). We experienced an average combined bid market share in the U.S. of 37% over the prior three years, including 49%, 55%, 19% and 34% of the domestic capital, coastal protection, maintenance and rivers & lakes sectors, respectively. As mentioned above, the Company’s largest domestic customer is the Corps, which has responsibility for federally funded projects related to navigation and flood control of U.S. waterways. Multi-jurisdictional cost sharing arrangements are allowing the Corps to utilize funds from sources other than the federal budget to prioritize additional projects where waterway infrastructure improvements can have an impact to large regions. 42 Although some of a project’s funding may ultimately be derived from multiple sources, the Corps maintains the authority over the project and is our customer. In 2021, our revenues earned from contracts with federal government agencies were approximately 78% of total revenue, mostly in line with our prior three-year average of 79%. During the second quarter of 2019, the Company completed the sale of our historical environmental & infrastructure business. The historical environmental & infrastructure segment has been retrospectively presented as discontinued operations and is no longer reflected in continuing operations. Refer to Note 13, “Business dispositions,” to our consolidated financial statements included in Item 15 of this Annual Report on Form 10-K. Contract Revenues Most of the Company’s contracts are obtained through competitive bidding on terms specified by the party inviting the bid. The types of equipment required to perform the specified service, project site conditions, the estimated project duration, seasonality, location and complexity of a project affect the cost of performing the contract and the price that contractors will bid. Fixed-price contracts, which comprise substantially all of the Company’s revenue, will most often represent a single performance obligation as the promise to transfer the individual services is not separately identifiable from other promises in the contracts and, therefore, not distinct. We capitalize certain pre-contract and pre-construction costs, and defer recognition over the life of the contract. Our performance obligations are satisfied over time and revenue is recognized using contract fulfillment costs incurred to date compared to total estimated costs at completion, also known as cost-to-cost, to measure progress towards completion. Contract modifications are changes in the scope or price (or both) of a contract that are approved by the parties to the contract. We recognize a contract modification when the parties to a contract approve a modification that either creates new, or changes existing, enforceable rights and obligations of the parties to the contract. Contract modifications are included in the transaction price only if it is probable that the modification estimate will not result in a significant reversal of revenue. Revisions in estimated gross profit percentages are recorded in the period during which the change in circumstances is experienced or becomes known. As the duration of most of our contracts are one year or less, the cumulative net impact of these revisions in estimates, individually and in the aggregate across our projects, does not significantly affect our results across annual reporting periods. Provisions for estimated losses on contracts in progress are made in the period in which such losses are determined. Costs and Expenses The components of costs of contract revenues include labor, equipment (including depreciation, maintenance, insurance and long-term rentals), subcontracts, fuel, supplies, short-term rentals and project overhead. Hourly labor generally is hired on a project-by-project basis. The Company is a party to numerous collective bargaining agreements in the U.S. that govern our relationships with our unionized hourly workforce. Primary Factors that Determine Operating Profitability The Company’s results of operations for a calendar or quarterly period are generally determined by the following three factors: • Bid wins and dredge employment— The Company recognizes backlog upon a project being awarded. We begin to recognize revenues when a dredging contract commences a major activity on the project. The period prior to the commencement of a major activity for dredging projects can range from 45 days to six months depending on the complexity of the project and environmental work windows. Although our dredging fleet is subject to downtime for scheduled periodic maintenance and regulatory dry dockings, we seek to maximize our revenues by employing our dredging fleet on a full-time basis. If a 43 dredge is idle (i.e., the dredge is not employed on a dredging project or undergoing scheduled periodic maintenance and repair), we do not earn revenue with respect to that dredge during the time period for which it is idle. • Project and dredge mix — The Company’s domestic dredging projects generally involve capital, maintenance, coastal protection and rivers & lakes work, while our foreign dredging projects generally involve capital work. In addition, our projects vary in duration which is generally driven by the type of work undertaken. In general, projects of longer duration result in less dredge downtime in a given period. For example, capital deepening projects generally span several years due to their complexity and environmental windows. Moreover, our dredges have different physical performance capabilities and typically work on certain types of dredging projects. Accordingly, our dredges have different daily revenue generating capacities. We generally expect to achieve different levels of gross profit margin (i.e., gross profit divided by revenues) for work performed on the different types of dredging projects and for work performed by different types of dredges. Our expected gross margin for a project is based upon our estimates at the time of the bid. Although we seek to bid on and win projects that will maximize our gross margin, we cannot control the type of dredging projects that are available for bid from time to time, the type of dredge that is needed to complete these projects, the competitive landscape at the time of bid or the time schedule upon which these projects are required to be completed. As a result, in some quarters the Company works on a mix of dredging projects that, in the aggregate, have relatively high expected gross margins (based on project type and dredges employed) and in other quarters, we work on a mix of dredging projects that, in the aggregate, have relatively low expected gross margins (based on project type and dredges employed). • Project execution—The Company seeks to execute all of our projects consistent with or at a higher production than our as-bid project estimates. In general, our ability to achieve our project estimates depends upon many factors including soil conditions, weather, variances from estimated project conditions, equipment mobilization time periods, unplanned equipment downtime, COVID-19 outbreaks or other events or circumstances beyond our control. If we experience any of these events and circumstances, the completion of a project will often be accelerated or delayed, as applicable, and, consequently, we will experience project results that are better or worse than our estimates. We do our best to estimate for events and circumstances that are not within our control; however, these situations are inherent in dredging. Critical Accounting Policies and Estimates The Company’s significant accounting policies are discussed in the Notes to our consolidated financial statements included in Item 15 of this Annual Report on Form 10-K. The application of certain of these policies requires significant judgments or an estimation process that can affect our results of operations, financial position and cash flows, as well as the related footnote disclosures. We base our estimates on historical experience and other assumptions that we believe are reasonable. If actual amounts are ultimately different from previous estimates, the revisions are included in our results of operations for the period in which the actual amounts become known. The following accounting policies comprise those that management believes are the most critical to aid in fully understanding and evaluating our reported financial results. Cost-to-cost method of revenue recognition— Revenue is recognized using contract fulfillment costs incurred to date compared to total estimated costs at completion, also known as cost-to-cost, to measure progress towards completion. Additionally, we capitalize certain pre-contract and pre-construction costs, and defer recognition over the life of the contract. In preparing estimates, we draw on our extensive experience in the dredging businesses. We use this experience in conjunction with the project specifications to select equipment and to design a production technique for a project. We also utilize our database of historical dredging information which includes daily costs, mobilization and dredge production references on the same or similar projects to ensure that our estimates are as accurate as possible, given current circumstances. The daily costs and project 44 duration are significant factors in our cost estimates to complete the project. Weather events, mechanical delays or other unplanned downtime instances may cause the actual costs to complete the project to differ from these estimates. Contract modifications are changes in the scope or price (or both) of a contract that are approved by the parties to the contract. We recognize a contract modification when the parties to a contract approve a modification that either creates new, or changes existing, enforceable rights and obligations of the parties to the contract. Contract modifications are included in the transaction price only if it is probable that the modification estimate will not result in a significant reversal of revenue. Contract modifications are routine in the performance of the Company’s contracts. In most instances, contract modifications are for services that are not distinct, and, therefore, are accounted for as part of the existing contract. Revisions in estimated gross profit percentages are recorded in the period during which the change in circumstances is experienced or becomes known. As the duration of most of the Company’s contracts is one year or less, the cumulative net impact of these revisions in estimates, individually and in the aggregate across projects, does not significantly affect results across annual reporting periods. Provisions for estimated losses on contracts in progress are made in the period in which such losses are determined. Impairment of goodwill—Goodwill is tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. The Company believes that this estimate is a critical accounting estimate because: (i) goodwill is a material asset and (ii) the impact of an impairment could be material to the consolidated balance sheet and consolidated statement of operations. We perform our annual impairment test as of July 1 each year. When conducting the annual impairment test for goodwill, the Company can choose to assess qualitative factors to determine whether it is more likely than not the fair value of the reporting unit is below its carrying value. If a qualitative assessment determines an impairment is more likely than not, the Company is required to perform a quantitative impairment test. Otherwise, no further analysis is required. The Company also may elect to forego this step and just perform the quantitative impairment test. In the current year, the Company elected to perform a qualitative goodwill impairment test. The Company performed its most recent annual test of impairment as of July 1, 2021 with no indication of impairment as of the test date. As of the test date, the Company determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. The Company has documented the qualitative considerations and determinations to support this conclusion. The Company will perform its next scheduled annual test of goodwill in the third quarter of 2022 should no triggering events occur which would require a test prior to the next annual test. At December 31, 2021 and 2020, our goodwill was $76.6 million. 45 Results of Operations—Fiscal Years Ended December 31, 2021, 2020 and 2019 The following table sets forth the components of net income attributable to common stockholders of Great Lakes Dredge & Dock Corporation and Adjusted EBITDA from continuing operations, as defined below, as a percentage of contract revenues for the years ended December 31 2021, 2020 and 2019. The selected financial data presented below have been derived from the Company’s consolidated financial statements; items may not sum due to rounding. Contract revenues Costs of contract revenues Gross profit General and administrative expenses Proceeds from loss of use claim Gain (loss) on sale of assets—net Operating income Interest expense—net Other income Income from continuing operations before income taxes Income tax provision Income from continuing operations Loss from discontinued operations, net of income taxes Net income Adjusted EBITDA from continuing operations 2021 2020 2019 100.0% 100.0% 100.0% (76.7) (80.0) (78.4) 20.0 (8.6) — — 11.4 (3.0) 0.1 8.5 (1.8) 6.7 — 23.3 (8.6) 0.2 0.2 15.1 (3.6) 0.2 11.7 (2.8) 8.9 — 21.6 (8.3) 0.6 (0.2) 13.7 (3.9) — 9.8 (2.1) 7.7 (0.9) 6.7 8.9 17.6% 20.6% 19.1% 6.8 Adjusted EBITDA from Continuing Operations Adjusted EBITDA from continuing operations, as provided herein, represents net income attributable to common stockholders of Great Lakes Dredge & Dock Corporation, adjusted for net interest expense, income taxes, depreciation and amortization expense, debt extinguishment, accelerated maintenance expense for new international deployments, goodwill or asset impairments and gains on bargain purchase acquisitions. Adjusted EBITDA from continuing operations is not a measure derived in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Company presents Adjusted EBITDA from continuing operations as an additional measure by which to evaluate our operating trends. We believe that Adjusted EBITDA from continuing operations is a measure frequently used to evaluate performance of companies with substantial leverage and that our primary stakeholders (i.e., its stockholders, bondholders and banks) use Adjusted EBITDA from continuing operations to evaluate our period to period performance. Additionally, management believes that Adjusted EBITDA from continuing operations provides a transparent measure of our recurring operating performance and allows management to readily view operating trends, perform analytical comparisons and identify strategies to improve operating performance. For this reason, we use a measure based upon Adjusted EBITDA to assess performance for purposes of determining compensation under our incentive plan. Adjusted EBITDA from continuing operations should not be considered an alternative to, or more meaningful than, amounts determined in accordance with GAAP including: (a) operating income as an indicator of operating performance; or (b) cash flows from operations as a measure of liquidity. As such, the Company’s use of Adjusted EBITDA from continuing operations, instead of a GAAP measure, has limitations as an analytical tool, including the inability to determine profitability or liquidity due to the exclusion of accelerated maintenance expense for new international deployments, goodwill or asset impairments, gains on bargain purchase acquisitions, net interest expense and income tax expense and the associated significant cash requirements and the exclusion of depreciation and amortization, which represent significant and unavoidable operating costs given the level of indebtedness and capital expenditures needed to maintain our business. For these reasons, we use operating income to measure our operating performance and use Adjusted EBITDA from 46 continuing operations only as a supplement. The following is a reconciliation of Adjusted EBITDA from continuing operations to net income attributable to common stockholders of Great Lakes Dredge & Dock Corporation (in thousands): Year Ended December 31, 2020 2021 2019 Net income Loss from discontinued operations, net of income $ 49,432 $ 66,103 $ 49,339 taxes Income from continuing operations Adjusted for: Interest expense—net Income tax provision Depreciation expense — — 49,432 66,103 21,601 13,391 43,016 26,585 20,187 38,183 (6,329) 55,668 27,524 15,253 37,145 Adjusted EBITDA $127,440 $151,058 $135,590 Components of Contract Revenues The following table sets forth, by type of work, the Company’s contract revenues for the years ended December 31, (in thousands): Revenues Capital—U.S. Capital—foreign Coastal protection Maintenance Rivers & lakes Total revenues 2021 2020 2019 $397,034 6,596 169,678 132,551 20,290 $336,163 25,892 201,361 148,767 21,418 $299,706 48,619 182,369 104,753 76,071 $726,149 $733,601 $711,518 Year Ended December 31, 2021 Compared to Year Ended December 31, 2020 Total revenue was $726.1 million in 2021, a decrease of $7.5 million, or 1.0%, from 2020 total revenue of $733.6 million. The decrease in revenues from the prior year was largely attributable to decreases in coastal protection, foreign capital and maintenance revenues. This decrease was partially offset by an increase in domestic capital revenues during the current year as compared to the prior year. The Company categorizes revenue by service type to understand the market in which we operate and to assess how we are performing on bidding work or projects and are generating revenue from backlog. Domestic capital dredging revenues increased $60.8 million, or 18.1%, to $397.0 million in 2021 when compared to 2020 revenues of $336.2 million. The increase in domestic capital dredging revenue from the prior year was primarily driven by greater revenue earned from deepening projects in Louisiana, Alabama, Massachusetts and South Carolina. This increase was partially offset by a decrease in revenue earned on projects in Florida and costal restoration projects in Louisiana and Mississippi. We earned 85% of backlog relating to our domestic capital dredging operations that had been carried forward from December 31, 2020. Revenues from foreign dredging operations in 2021 totaled $6.6 million, a decrease of $19.3 million, or 74.5%, from 2020 revenues of $25.9 million. The decrease in foreign dredging revenue was driven by decreased revenue earned on a project in Bahrain in 2021 as compared to 2020. We earned 100% of backlog relating to our foreign dredging operations that had been carried forward from December 31, 2020. 47 Coastal protection revenues were $169.7 million in 2021, a decrease of $31.7 million, or 15.7%, from $201.4 million in 2020. The decrease in coastal protection revenue for the year ended December 31, 2021 was mostly attributable to a lower amount of revenue earned on projects in Virginia, South Carolina and New York and New Jersey in the current year as compared to the prior year. This decrease was partially offset by a greater amount of revenue earned on projects in Florida and North Carolina in the current year compared to the prior year. We earned 98% of backlog relating to coastal protection operations that had been carried forward from December 31, 2020. Revenues from maintenance dredging projects in 2021 were $132.6 million, a decrease of $16.2 million, or 10.9%, from $148.8 million in 2020. The decrease in maintenance revenue during the current year was mostly attributable to lower revenue earned on projects in Maryland, Virginia, New York and New Jersey in the current year compared to the prior year. This decrease was partially offset by greater revenue earned on projects in Louisiana and Florida in the current year. We earned 95% of backlog relating to maintenance dredging projects that had been carried forward from December 31, 2020. Rivers & lakes revenues were $20.3 million for 2021, a decrease of $1.1 million, or 5.1%, from $21.4 million in 2020. The decrease in rivers & lakes revenue during the current year was mostly attributable to a greater amount of revenue earned during the prior year on a large flood mitigation project in Texas as a result of Hurricane Harvey, as well as a project in Nebraska, when compared to the current year. This decrease was partially offset by revenue earned on projects in Tennessee and Mississippi in the current year. We earned 100% of backlog relating to rivers & lakes operations that had been carried forward from December 31, 2020. Gross profit for the year ended December 31, 2021 decreased by $25.9 million, or 15.1%, to $145.3 million from $171.2 million for the year ended December 31, 2020. Gross profit margin (gross profit divided by revenue) for the full year 2021 was 20.0%, lower than prior year gross profit margin of 23.3%. The lower gross profit for 2021 was mostly driven by increased costs related to COVID-19 for items such as testing, vessel cleaning, crew quarantining and replacement staffing. In addition, we also had production impacts due to COVID-19 which are not as easy to quantify, but negatively impacted gross margin due to crew shortages, vessel dry dock delays and rescheduling of vessels on projects. General and administrative expenses totaled $62.1 million for the year ended December 31, 2021, down from $62.8 million for the year ended December 31, 2020. The decrease was attributable to decreases in incentive pay compared to the prior year, partially offset by increases in relocation costs and technical and consulting fees of $2.0 million and $1.9 million, respectively. Operating income was $83.4 million and $111.8 million for the years ended December 31, 2021 and 2020, respectively. The decrease in operating income during the year ended December 31, 2021 was a result of lower gross profit, partially offset by a decrease in general and administrative expenses, as described above. Additionally, there was a $1.3 million greater gain on sale of assets and $1.7 million of proceeds from loss of use claims in the prior year which contributed to the lower operating income in the current year. The Company’s net interest expense for 2021 totaled $21.6 million compared to $26.6 million in 2020. The decrease in net interest expense was attributable to a decrease of $5.2 million in interest expense related to the more favorable interest rate with the new senior note refinancing in the current year. Income tax provision in 2021 was $13.4 million, compared to an income tax provision of $20.2 million in 2020. The decrease in income tax provision is primarily related to lower pretax income during the current year, as described above. The effective tax rate for the year ended December 31, 2021 was 21.3%, below the effective tax rate of 23.4% for the same period of 2020. The lower effective tax rate in the current year was due to a one-time benefit associated with a stock compensation deduction in the current year and an adjustment of tax basis used during the preparation of our prior year provision. 48 For the year ended December 31, 2021, net income was $49.4 million compared to net income of $66.1 million for the year ended December 31, 2020. The decrease in net income of $16.7 million, down 25.3% from 2020, was driven by the decrease to gross profit, as described above. Additionally, there was a $1.3 million greater gain on sale of assets in the prior year and $1.7 million in proceeds from loss of use claims in the prior year that contributed to greater net income in the prior year. The decrease was partially offset by a $6.8 million decrease in the income tax provision, a $5.2 million decrease in net interest expense related to the more favorable senior note interest rates and a $0.7 million decrease to general and administrative expenses during the current year when compared to the prior year. Adjusted EBITDA (as defined and reconciled on page 46 to 47) was $127.4 million and $151.1 million for the years ended December 31, 2021 and 2020, respectively. The decrease in Adjusted EBITDA of $23.7 million, down 15.7% from 2020 was attributable to lower gross profit, excluding depreciation, partially offset by a decrease in general and administrative expenses. Additionally, there was a $1.3 million greater gain on sale of assets in the prior year and $1.7 million in proceeds from loss of use claims in the prior year that contributed to higher Adjusted EBITDA in the prior year. Year Ended December 31, 2020 Compared to Year Ended December 31, 2019 For a discussion comparing our consolidated operating results from the year ended December 31, 2020 with the year ended December 31, 2019, refer to Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operation – Year Ended December 31, 2020 Compared to Year Ended December 31, 2019” in our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the Commission on February 24, 2021. Bidding Activity and Backlog The following table sets forth, by type of work, the Company’s backlog as of the dates indicated (in thousands): Backlog Capital—U.S. Capital—foreign Coastal protection Maintenance Rivers & lakes Total Backlog December 31, 2021 December 31, 2020 December 31, 2019 $398,748 — 99,048 50,966 2,826 $551,588 $320,920 6,865 97,986 125,090 8,515 $559,376 $347,377 30,571 141,039 60,891 9,528 $589,406 The Company’s contract backlog represents our estimate of the revenues that will be realized under the portion of the contracts remaining to be performed. These estimates are based primarily upon the time and costs required to mobilize the necessary assets to and from the project site, the amount and type of material to be dredged and the expected production capabilities of the equipment performing the work. However, these estimates are necessarily subject to variances based upon actual circumstances. Because of these factors, as well as factors affecting the time required to complete each job, backlog is not always indicative of future revenues or profitability. Also, 62% of our December 31, 2021 backlog relates to federal government contracts, which can be canceled at any time without penalty to the government, subject to our contractual right to recover our actual committed costs and profit on work performed up to the date of cancellation. Our backlog may fluctuate significantly from quarter to quarter based upon the type and size of the projects we are awarded from the bid market. A quarterly increase or decrease of our backlog does not necessarily result in an improvement or a deterioration of our business. Our backlog includes only those projects for which we have obtained a signed contract with the customer. 49 Approximately 88% of the Company’s backlog at December 31, 2021 is expected to be completed and converted to revenue in 2022. The 2021 domestic dredging bid market totaled $1.82 billion, an increase of $26 million, or 1.5%, compared to the 2020 bid market total of $1.79 billion. Total domestic dredging bid market for the current year period included awards for Thimble Shoal, Portsmouth, Houston deepening and additional phase of the Boston Harbor, Mobile Deepening and Corpus Christi deepening projects. It also included awards for multiple coastal restoration projects which includes three projects in Florida, two in New Jersey and North Carolina, and one in New York. Additionally, the 2021 bid market included awards for maintenance work on the Jacksonville Harbor, Memphis, Mississippi River and South Atlantic region. There were increases in domestic capital and Costal Protection projects let to bid in the current period and decreases in maintenance and rivers and lakes projects. The Company won 40% of the overall 2021 domestic bid market, up from a 39% win rate of the overall 2020 domestic bid market. Variability in contract wins from period to period is not unusual. We believe trends in our win rate over the prior three-year periods provide a historical background against which current year results can be compared. The Company’s December 31, 2021 contracted backlog was $551.6 million. This represents a decrease of $7.8 million, or 1.4%, over our December 31, 2020 backlog of $559.4 million. Backlog at the end of 2021 does not reflect approximately $567.3 million of domestic low bids pending formal award and additional phases (“options”) pending on projects currently in backlog, including two large LNG projects. At December 31, 2020, the amount of domestic low bids pending award was $472.3 million. The Company won 64%, or $457.7 million, of the domestic capital dredging projects awarded in 2021, compared to 49%, or $308.7 million, in the prior year. During 2021, the Company was awarded third phase of the Boston Harbor deepening project for $61.8 million, the additional phase of the Corpus Christi deepening project for $139 million, a third phase of Mobile deepening project for $53.9 million, the Thimble Shoal deepening and renourishment project for $38.4 million, the Portsmouth capital project for $25.6 million and Houston deepening for $92.5 million. Domestic capital dredging work made up $398.7 million, or 72%, of our December 31, 2021 contracted backlog. During 2021, the Company continued to earn revenue on deepening projects in Charleston, Jacksonville, the Gulf Coast region, two coastal restoration projects in Louisiana and a liquefied natural gas project in Louisiana, which were in backlog at December 31, 2020. We expect 86% of our domestic capital backlog at December 31, 2021 to be performed in 2022, with the remainder to be performed in 2023. Government funded projects coming into the pipeline include new deepenings for ports in Houston, the Norfolk Harbor Deepening and Freeport Reaches in the Gulf Region. These deepenings continue the trend of ensuring all East Coast and Gulf of Mexico ports will be able to accommodate the deeper draft vessels currently used on several trade routes. The nation’s governors continue to show commitment to their respective ports through engagement and funding. Finally, Congress has also shown a commitment to ports and waterways, providing record annual budgets for the Corps for port deepening and channel maintenance. In addition to this port work, a greater amount of coastal restoration and rehabilitation projects are being funded in the Gulf Coast region as the states utilize available monies for ecosystem priorities, a portion of which is allocated to dredging. Foreign capital dredging backlog decreased to $0 at December 31, 2021 from $6.9 million at the end of 2020. As expected, all of our foreign capital backlog at December 31, 2020 was performed in 2021 with no future foreign projects in the pipeline. The Company won 58%, or $195.9 million, of the coastal protection projects awarded in 2021, compared to 65%, or $152.3 million, in the prior year. During 2021, the Company was awarded three coastal protection projects of $28.5 million, $15.6 million and $11.3 million in Florida, two coastal protection projects in New Jersey for $12.1 million and $26.6 million, and one in New York and North Carolina for $47.5 million and $17.1, respectively. We have contracted backlog related to coastal protection of $99.0 million at December 31, 2021 compared to $98.0 million at the end of 2020. During the year ended December 31, 2021, the Company continued to earn revenue on coastal protection projects in North Carolina, Florida. New Jersey and Louisiana which were in backlog at December 31, 2020. We expect approximately all of our coastal protection backlog at 50 December 31, 2021 to be performed in 2022. Coastal protection and storm impacts continue to provide the major impetus for coastal project investment at federal and state levels. As a result of the extreme storm systems in prior years involving Hurricanes Harvey, Irma, and Maria, the U.S. Congress passed supplemental appropriations for disaster relief and recovery which includes $17.4 billion for the Corps to fund projects that will reduce the risk of future damage from flood and storm events. The Corps is beginning to provide visibility on its plans for this money, and it is expected that approximately $1.8 billion will be allocated to dredging-related work. Most of this work is anticipated to be coastal protection related, but some funding may be provided for channel maintenance. During 2019, an additional $3.3 billion of supplemental appropriations was approved for disaster relief funding as a result of Hurricane Florence and Hurricane Michael. During September 2021, a supplemental bill was passed that included approximately $5.7 billion for emergency funding as a result of Hurricane Ida impacts. Additionally, in 2021, the U.S. Senate passed the $1.2 trillion infrastructure bill where the Corps will be granted $11.6 billion in funding to improve the nation’s resilience to the effects of climate change. The Company won 8%, or $57.4 million, of the maintenance dredging projects awarded in 2021 compared to 27%, or $199.7 million, in 2020. During 2021 the Company was awarded a maintenance project of $24.3 million in the Louisiana, a $3.3 million project in Florida and a $25.7 million project in the South Atlantic Regional Harbor. During the year ended December 31, 2021, the Company continued to earn revenue on projects in Louisiana, North Carolina, Florida and Texas which were in backlog at December 31, 2020. Our contracted maintenance dredging backlog at December 31, 2021 of $51.0 million is $74.1 million lower than the backlog of $125.1 million at December 31, 2020. We expect 88% of our maintenance dredging backlog at December 31, 2021 to be performed in 2022. Past Water Resources Development Act (“WRDA”) bills called for full use of the Harbor Maintenance Trust Fund (“HMTF”) for its intended purpose of maintaining future access to the waterways and ports that support our nation’s economy. On March 27, 2020, the U.S. government enacted the CARES Act which includes a provision that lifts caps on the HMTF, thereby allowing full access to future annual revenues. The 2020 Water Resources Development Act (WRDA) legislation was included in the Consolidated Appropriations Act 2021 signed into law on December 27, 2020. This continues the trend of WRDA legislation in each session of Congress since 2014. The legislation provides access to the $9.3 billion in unspent HMTF tax collections, establishes a funds distribution process for HMTF funding and approves projects to proceed to construction. Through the increased appropriation of HMTF monies, the Company anticipates increased funding for harbor maintenance projects to be let for bid. The Company won 31%, or $24.0 million, of the rivers & lakes projects in the markets where the group operates during the current year, compared to 17%, or $32.1 million, in 2020. During the current year, the Company was awarded one rivers & lakes project in Tennessee and one project in Louisiana. For the year ended December 31, 2021, we continued to earn revenue on a project in Kansas, Texas and Mississippi which was in backlog at December 31, 2020. We have contracted dredging backlog related to rivers & lakes of $2.8 million at December 31, 2021, which is $5.7 million lower than the backlog of $8.5 million at December 31, 2020. We expect approximately all of our rivers & lakes backlog at December 31, 2021 to be performed in 2022. Liquidity and Capital Resources The Company’s principal sources of liquidity are net cash flows provided by operating activities, availability under our revolving credit facility and proceeds from issuances of long-term debt. See Note 6, “Long-term debt,” to our consolidated financial statements included in Item 15 of this Annual Report on Form 10-K. Our principal uses of cash are to meet debt service requirements, finance capital expenditures, and provide working capital and other general corporate purposes. The Company’s net cash provided by operating activities of continuing operations for the years ended December 31, 2021, 2020 and 2019 totaled $49.0 million, $78.9 million and $201.8 million, respectively. Normal increases or decreases in the level of working capital relative to the level of operational activity impact cash flow from operating activities. The decrease in cash provided by operating activities of continuing operations during 2021 compared to the same period in the prior year was driven by a decrease in net income and an increase in 51 working capital primarily due to an increase in receivables during the current year when compared to the same period in the prior year. This decrease was partially offset by a decrease in the non-cash deferred income taxes recorded in net income in the current year when compared to the prior year period. Cash provided by operating activities for the year ended December 31, 2020 was down compared to 2019 due to higher working capital components during 2020. The Company’s net cash flows used in investing activities of continuing operations for the years ended December 31, 2021, 2020 and 2019 totaled $112.2 million, $43.2 million and $43.8 million, respectively. Investing activities in all periods primarily relate to normal course upgrades and capital maintenance of our dredging fleet. The Company is currently building a 6,500 cubic yard trailing suction hopper dredge with expected delivery in the first quarter of 2023. In November 2021, the Company entered into a $197 million contract with Philly Shipyard to build the first U.S. flagged Jones Act compliant, inclined fall-pipe vessel for subsea rock installation for wind turbine foundations to support the new U.S. offshore wind industry. In July 2021, the Company announced a contract to build two multifunctional all-purpose vessels (“multicats”). During the twelve months ended December 31, 2021, the Company has invested $65.5 million towards these new vessels along with smaller scow vessels. In addition, the Company spent $16.4 million to acquire two dredges that had previously been leased. In 2021, 2020 and 2019, we received $4.5 million, $4.5 million and $5.6 million, respectively, in proceeds from dispositions of property and equipment. The Company’s net cash flows used in financing activities of continuing operations for the years ended December 31, 2021, 2020 and 2019 totaled $5.9 million, $6.3 million and $14.1 million, respectively. On August 4, 2020, the Company announced that its board of directors approved a share repurchase program, authorizing, but not obligating, the repurchase of up to an aggregate amount of $75.0 million of its common stock from time to time through July 31, 2021. The decrease in cash used in financing activities primarily relates to the absence of stock repurchases being made in 2021 and a decrease in taxes paid on settlement of vested shares awards partially offset by an increase in $4.4 million of deferred financing fees paid related to the new $325 million of unsecured 5.25% Senior Notes (the “2029 Notes”). Of the previously announced $75.0 million share repurchase program, the Company repurchased $3.9 million of common stock during 2020 and none during the period ended December 31, 2021. The Company maintains a favorable cash on hand position and revolver availability and as a result is well positioned for changes in the current economic environment. To date, the Company has had various operational or financial impacts as a result of the ongoing COVID-19 pandemic and will continue to assess the potential economic impact that the virus and actions taken to contain it could have on the Company’s operations and liquidity. Commitments, contingencies and liquidity matters Refer to Note 6, “Long-term debt,” in the Notes to Condensed Consolidated Financial Statements for discussion of the Company’s Amended Credit Agreement and Senior Notes. Additionally, refer to Note 12, “Commitments and contingencies,” in the Notes to Condensed Consolidated Financial Statements for discussion of the Company’s surety agreements. Other The future declaration and payment of dividends will be at the discretion of the Company’s board of directors and will depend on many factors, including general economic and business conditions, our strategic plans, our financial results and condition and legal requirements, including restrictions and limitations contained in the Amended Credit Agreement, surety bonding agreement and the indenture relating to our senior notes. Accordingly, we cannot make any assurances as to the size of any such dividend or that it will pay any such dividend in future quarters. 52 The Company believes our cash and cash equivalents, our anticipated cash flows from operations and availability under our revolving credit facility will be sufficient to fund our operations, capital expenditures and the scheduled debt service requirements for the next twelve months. Beyond the next twelve months, our ability to fund our working capital needs, planned capital expenditures, scheduled debt payments and dividends, if any, and to comply with all the financial covenants required under the Amended Credit Agreement, depends on our future operating performance and cash flows, which in turn are subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond our control. Contractual Obligations Additional information related to contractual obligations can be found within this Item 7 in our “Liquidity and Capital Resources” section and also in Note 6, “Long-term debt,” and Note 12, “Commitments and contingencies,” to our consolidated financial statements. Other Off-Balance Sheet and Contingent Obligations The Company had outstanding letters of credit relating to contract guarantees and insurance payment liabilities totaling $25.1 million at December 31, 2021. We have granted liens on a substantial portion of the owned operating equipment as security for borrowings under the Amended Credit Agreement and other indebtedness. At December 31, 2021, the Company had outstanding performance bonds with a notional amount of $1,164.8 million of which $17.4 million relates to projects from our historical environmental & infrastructure businesses. The revenue value remaining in backlog related to the projects in continuing operations totaled $551.6 million. Certain foreign projects performed by the Company have warranty periods, typically spanning no more than one to three years beyond project completion, whereby we retain responsibility to maintain the project site to certain specifications during the warranty period. Generally, any potential liability of the Company is mitigated by insurance, shared responsibilities with consortium partners, and/or recourse to owner-provided specifications. The Company considers it unlikely that it would have to perform under any of its contingent obligations. Item 7A. Quantitative and Qualitative Disclosures about Market Risk In May 2021, the Company sold $325 million of unsecured 5.25% Senior Notes due June 1, 2029 pursuant to a private offering. The Company used the net proceeds from the offering, together with cash on hand, to redeem all $325 million aggregate principal amount of its prior outstanding 8% Notes. The 2029 Notes were priced to investors at par and will mature on June 1, 2029. At December 31, 2021, the Company had long-term senior notes outstanding with a recorded face value of $325.0 million. The fair value of these existing notes, which bear interest at a fixed rate of 5.25%, was $334.8 million at December 31, 2021 based on market prices. Assuming a 10% decrease in interest rates from the rates at December 31, 2021 the fair value of this fixed rate debt would have increased to $345.0 million. A significant operating cost for the Company is diesel fuel, which represents approximately 8% of our costs of contract revenues. We use fuel commodity forward contracts, typically with durations of less than one year, to reduce the impacts of changing fuel prices on operations. We do not purchase fuel hedges for trading purposes. Based on our 2022 projected domestic fuel consumption, an approximate 10% increase in the average price per gallon of fuel would have a $0.6 million effect on fuel expense, after the effect of fuel commodity contracts in place at December 31, 2021. At December 31, 2021 we had outstanding arrangements to hedge the price of a portion of our fuel purchases related to domestic dredging work in backlog, representing approximately 80% of its anticipated domestic fuel requirements through December 2022. As of December 31, 2021, there were 53 10.2 million gallons remaining on these contracts. Under these agreements, we will pay fixed prices ranging from $1.25 to $2.46 per gallon. At December 31, 2021, the fair value asset on these contracts was $0.6 million, based on quoted market prices and is recorded in other current assets. A 10% change in forward fuel prices would result in a $2.5 million change in the fair value of fuel hedges outstanding at December 31, 2021. Item 8. Financial Statements and Supplementary Data The consolidated financial statements (including financial statement schedules listed under Item 15 of this Report) of the Company called for by this Item, together with the Report of Independent Registered Public Accounting Firm dated February 23, 2022, are set forth on pages 63 to 88 inclusive, of this Report, and are hereby incorporated by reference into this Item. Financial statement schedules not included in this Report have been omitted because they are not applicable or because the information called for is shown in the consolidated financial statements or notes thereto. 54 Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures Disclosure Controls and Procedures. a) Evaluation of disclosure controls and procedures Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”) as of December 31, 2021. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act (a) is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding disclosure and (b) is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures, as designed and implemented, were effective as of December 31, 2021. Notwithstanding the foregoing, a control system, no matter how well designed, implemented and operated can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in our periodic reports. b) Changes in internal control over financial reporting There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. c) Management’s annual report on internal control over financial reporting The management of Great Lakes Dredge & Dock Corporation, including its Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f), and 15d-15(f) under the Securities Exchange Act of 1934). Management has used the framework set forth in the report entitled Internal Control—Integrated Framework (2013) published by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) to evaluate the effectiveness of the Company’s internal control over financial reporting. The phrase internal control over financial reporting refers to the process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer, and overseen by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that: • • Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with general accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and 55 • Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements. Neither internal control over financial reporting nor disclosure controls and procedures can provide absolute assurance of achieving financial reporting objectives because of their inherent limitations. Internal control over financial reporting and disclosure controls are processes that involve human diligence and compliance, and are subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting and disclosure controls also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented, detected or reported on a timely basis by internal control over financial reporting or disclosure controls. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design safeguards for these processes that will reduce, although may not eliminate, these risks. Our independent registered public accounting firm, Deloitte & Touche LLP, who audited Great Lakes’ consolidated financial statements included in this Annual Report on Form 10-K, has issued a report on Great Lakes’ internal control over financial reporting, which is included herein. Management has concluded that our internal control over financial reporting was effective as of December 31, 2021. 56 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the stockholders and the Board of Directors of Great Lakes Dredge & Dock Corporation Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Great Lakes Dredge & Dock Corporation and subsidiaries (the “Company”) as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2021, of the Company and our report dated February 23, 2022, expressed an unqualified opinion on those financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Deloitte & Touche LLP Chicago, Illinois February 23, 2022 57 Item 9B.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 23, 2022, expressed an unqualified opinion on the Company’s internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Revenue Recognition – Estimated Costs at Completion— Refer to Notes 1 and 10 to the financial statements Critical Audit Matter Description During 2021, the Company’s contract revenues were $726.1 million, all of which represented revenue recognized over time as work progressed on individual contracts. The Company recognizes revenue on its contracts utilizing 61 the cost-to-cost method for determining progress toward completion of each contract. Revenue is recognized using contract fulfillment costs incurred to date compared to total estimated fulfillment costs at completion. Daily costs and project duration are significant factors in management’s estimate of fulfillment costs at completion. We identified estimated contract fulfillment costs at completion used in revenue recognition as a critical audit matter because of the judgments inherent in management’s estimates related to contracts that were in progress at December 31, 2021. This required extensive audit effort and a high degree of auditor judgment when performing audit procedures on the total estimated contract fulfillment costs which underlie management’s determination of revenue on contracts in progress. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to contract fulfillment costs incurred to date and management’s estimates of the total costs at completion for contracts in progress included the following, among others: • We tested the effectiveness of internal controls over revenue recognition, including management’s internal controls over contract fulfillment costs incurred to date and estimated total costs at completion. • We selected a sample of contracts with customers and we performed the following: • Tested management’s process of determining the estimated cost to complete the contract and evaluated management’s ability to achieve the estimates of total cost by obtaining relevant support and inquiring with the Company’s project managers and engineers, comparing the estimates to management’s work plans, and comparing expected profit margins to those achieved on similar contracts to determine whether the estimates were within an acceptable range. • For certain contracts, we performed in-person or virtual site visits and held meetings with the project site managers to discuss the contract activities. We utilized global positioning system tracking technology to validate equipment deployed on-site for site visits held virtually. • We evaluated management’s ability to accurately estimate contract fulfillment costs at completion by performing a hindsight analysis using historical contracts and comparing the margin at contract inception compared to margin at contract completion. • We tested the accuracy and occurrence of contract fulfillment costs incurred to date by selecting a sample of costs from contract cost general ledger detail and obtaining supporting documentation in the form of invoices or pay statements and time-charged records. • We compared total actual costs incurred on projects completed during the year to management’s estimates as of the prior year end to evaluate management’s ability to accurately forecast total contract fulfillment costs at completion. /s/ Deloitte & Touche LLP Chicago, Illinois February 23, 2022 We have served as the Company’s auditor since 1991. 62 Great Lakes Dredge & Dock Corporation and Subsidiaries Consolidated Balance Sheets As of December 31, 2021 and 2020 (in thousands, except per share amounts) ASSETS CURRENT ASSETS: Cash and cash equivalents Accounts receivable—net Contract revenues in excess of billings Inventories Prepaid expenses Other current assets Total current assets PROPERTY AND EQUIPMENT—Net OPERATING LEASE ASSETS GOODWILL INVENTORIES—Noncurrent OTHER TOTAL LIABILITIES AND EQUITY CURRENT LIABILITIES: Accounts payable Accrued expenses Operating lease liabilities Billings in excess of contract revenues Total current liabilities LONG-TERM DEBT OPERATING LEASE LIABILITIES—Noncurrent DEFERRED INCOME TAXES OTHER Total liabilities COMMITMENTS AND CONTINGENCIES (Note 12) EQUITY: Common stock—$.0001 par value; 90,000 authorized, 65,746 and 65,023 shares issued and outstanding at December 31, 2021 and December 31, 2020, respectively.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS AS OF December 31, 2021 AND 2020 AND FOR THE YEARS ENDED December 31, 2021, 2020 AND 2019 (In thousands, except per share amounts or as otherwise noted) 1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization—Great Lakes Dredge & Dock Corporation and its subsidiaries (the “Company” or “Great Lakes”) are in the business of marine construction, primarily dredging. The Company is the largest provider of dredging services in the United States. In addition, the Company has a long history of performing significant international projects. The mobility of the Company’s fleet enables the Company to move equipment in response to changes in demand for dredging services Principles of Consolidation and Basis of Presentation—The consolidated financial statements include the accounts of Great Lakes Dredge & Dock Corporation and its majority-owned subsidiaries. All intercompany accounts and transactions are eliminated in consolidation. The equity method of accounting is used for investments in unconsolidated investees in which the Company has significant influence, but not control. Other investments, if any, are carried at cost. Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Revenue and Cost Recognition on Contracts—Revenue is recognized using contract fulfillment costs incurred to date compared to total estimated costs at completion, also known as cost-to-cost, to measure progress towards completion. Additionally, the Company capitalizes certain pre-contract and pre-construction costs, and defers recognition over the life of the contract. The Company’s performance obligations are satisfied over time and revenue is recognized using the cost-to-cost method, described above. Contract modifications are changes in the scope or price (or both) of a contract that are approved by the parties to the contract. The Company recognizes a contract modification when the parties to a contract approve a modification that either creates new, or changes existing, enforceable rights and obligations of the parties to the contract. Contract modifications are routine in the performance of the Company’s contracts. In most instances, contract modifications are for services that are not distinct, and, therefore, are accounted for as part of the existing contract. Contract modifications are included in the transaction price only if it is probable that the modification estimate will not result in a significant reversal of revenue. Revisions in estimated gross profit percentages are recorded in the period during which the change in circumstances is experienced or becomes known. As the duration of most of the Company’s contracts is one year or less, the cumulative net impact of these revisions in estimates, individually and in the aggregate across projects, does not significantly affect results across annual reporting periods. Provisions for estimated losses on contracts in progress are made in the period in which such losses are determined. The components of costs of contract revenues include labor, equipment (including depreciation, maintenance, insurance and long-term rentals), subcontracts, fuel, supplies, short-term rentals and project overhead. Hourly labor generally is hired on a project-by-project basis. The Company is a party to numerous collective bargaining agreements in the U.S. that govern its relationships with its unionized hourly workforce. Classification of Current Assets and Liabilities—The Company includes in current assets and liabilities amounts realizable and payable in the normal course of contract completion, unless completion of such contracts extends significantly beyond one year. 69 Cash Equivalents—The Company considers all highly liquid investments with a maturity at purchase of three months or less to be cash equivalents. Accounts Receivable—Accounts receivable represent amounts due or billable under the terms of contracts with customers, including amounts related to retainage. The Company anticipates collection of retainage generally within one year, and accordingly presents retainage as a current asset. The Company provides an allowance for estimated uncollectible accounts receivable based on historical and expected losses and when events or conditions indicate that amounts outstanding are not recoverable. Inventories—Inventories consist of pipe and spare parts used in the Company’s dredging operations. Pipe and spare parts are purchased in large quantities; therefore, a certain amount of pipe and spare part inventories is not anticipated to be used within the current year and is classified as long-term. Spare part inventories are stated at weighted average historical cost, and are charged to expense when used in operations. Pipe inventory is recorded at cost and amortized to expense over the period of its use. Property and Equipment—Capital additions, improvements, and major renewals are classified as property and equipment and are carried at depreciated cost. Maintenance and repairs that do not significantly extend the useful lives of the assets or enhance the capabilities of such assets are charged to expenses as incurred. Depreciation is recorded over the estimated useful lives of property and equipment using the straight-line method and the mid-year depreciation convention. The estimated useful lives by class of assets are: Class Useful Life (years) Buildings and improvements Furniture and fixtures Vehicles, dozers, and other light operating equipment and systems Heavy operating equipment (dredges and barges) 10 5-10 3-5 10-30 Leasehold improvements are amortized over the shorter of their remaining useful lives or the remaining terms of the leases. Goodwill—Goodwill represents the excess of acquisition cost over fair value of the net assets acquired. Goodwill is tested annually for impairment in the third quarter of each year, or more frequently should circumstances dictate. GAAP requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When conducting the annual impairment test for goodwill, the Company can choose to assess qualitative factors to determine whether it is more likely than not the fair value of the reporting unit is below its carrying value. If a qualitative assessment determines an impairment is more likely than not, the Company is required to perform a quantitative impairment test. Otherwise, no further analysis is required. The Company also may elect to forego this step and just perform the quantitative impairment test. The Company has one operating segment which is also the Company’s one reportable segment and reporting unit of which the Company tests goodwill for impairment. In the current year, the Company elected to perform a qualitative goodwill impairment test in accordance with ASC 350-20. The Company performed its most recent annual test of impairment as of July 1, 2021 with no indication of impairment as of the test date. As of the test date, the Company determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. The Company has documented the qualitative considerations and determinations to support this conclusion. The Company will perform its next scheduled annual test of goodwill in the third quarter of 2022 should no triggering events occur which would require a test prior to the next annual test. 70 Long-Lived Assets—Long-lived assets are comprised of property and equipment subject to amortization. Long-lived assets to be held and used are reviewed for possible impairment whenever events indicate that the carrying amount of such assets may not be recoverable by comparing the undiscounted cash flows associated with the assets to their carrying amounts. If such a review indicates an impairment, the carrying amount would be reduced to fair value. No triggering events were identified in 2021 or 2020. If long-lived assets are to be disposed, depreciation is discontinued, if applicable, and the assets are reclassified as held for sale at the lower of their carrying amounts or fair values less estimated costs to sell. Self-insurance Reserves—The Company self-insures costs associated with its seagoing employees covered by the provisions of Jones Act, workers’ compensation claims, hull and equipment liability, and general business liabilities up to certain limits. Insurance reserves are established for estimates of the loss that the Company may ultimately incur on reported claims, as well as estimates of claims that have been incurred but not yet reported. In determining its estimates, the Company considers historical loss experience and judgments about the present and expected levels of cost per claim. Trends in actual experience are a significant factor in the determination of such reserves. Income Taxes—The provision for income taxes includes federal, foreign, and state income taxes currently payable and those deferred because of temporary differences between the financial statement and tax basis of assets and liabilities. Recorded deferred income tax assets and liabilities are based on the estimated future tax effects of differences between the financial and tax basis of assets and liabilities, given the effect of currently enacted tax laws. Refer to Note 8, Income Taxes. Hedging Instruments—At times, the Company designates certain derivative contracts as a cash flow hedge as defined by GAAP. Accordingly, the Company formally documents, at the inception of each hedge, all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking hedge transactions. This process includes linking all derivatives to highly-probable forecasted transactions. The Company formally assesses, at inception and on an ongoing basis, the effectiveness of hedges in offsetting changes in the cash flows of hedged items. Hedge accounting treatment may be discontinued when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the cash flows of a hedged item (including hedged items for forecasted future transactions), (2) the derivative expires or is sold, terminated or exercised, (3) it is no longer probable that the forecasted transaction will occur or (4) management determines that designating the derivative as a hedging instrument is no longer appropriate. If management elects to stop hedge accounting, it would be on a prospective basis and any hedges in place would be recognized in accumulated other comprehensive income (loss) until all the related forecasted transactions are completed or are probable of not occurring. Recent Accounting Pronouncements—In January 2021, the Financial Accounting Standards Board (“FASB”) amended ASU No. 2020-04 (“ASU 2020-04”) into ASU No. 2021-01 (“ASU 2021-01”), Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendment provides optional expedients and exceptions to applying the guidance on contract modifications, hedge accounting and other transactions to simplify the accounting for transitioning from the London Interbank Offered Rate (“LIBOR”), and other interbank offered rates expected to be discontinued, to alternative reference rates. The guidance in this update was effective upon its issuance; if elected, it is to be applied prospectively through December 31, 2022. The Company is currently evaluating the effect the potential adoption of this ASU will have on the Company’s consolidated financial statements. 2. EARNINGS PER SHARE Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share 71 is computed similar to basic earnings per share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock. The computations for basic and diluted earnings per share for the years ended December 31, 2021, 2020 and 2019 are as follows: (shares in thousands) Income from continuing operations Loss on discontinued operations, net of income taxes Net income Weighted-average common shares outstanding — basic Effect of stock options and restricted stock units 2021 2020 2019 $49,432 — $49,432 65,587 714 $66,103 — $66,103 64,743 1,129 $55,668 (6,329) $49,339 63,597 1,445 Weighted-average common shares outstanding — diluted 66,301 65,872 65,042 Earnings per share from continuing operations — basic Earnings per share from continuing operations — diluted $ $ 0.75 0.75 $ $ 1.02 1.00 $ $ 0.88 0.86 For the years ended December 31, 2021, 2020 and 2019, 1 thousand, 1 thousand and 16 thousand, respectively, non-qualified stock options (“NQSOs”) and restricted stock units (“RSUs”) were excluded from the calculation of diluted earnings per share based on the application of the treasury stock method, as such NQSOs and RSUs were determined to be anti-dilutive. 3. PROPERTY AND EQUIPMENT Property and equipment at December 31, 2021 and 2020 are as follows: Land Buildings and improvements Furniture and fixtures Operating equipment Total property and equipment Accumulated depreciation Property and equipment — net 2021 2020 $ 9,992 1,315 18,568 869,953 899,828 $ 9,992 1,315 17,251 762,350 790,908 (444,726) (407,866) $ 455,102 $ 383,042 Operating equipment of $2,900 was classified as held for sale, excluded from property and equipment, as of December 31, 2020. Depreciation expense was $43,016, $38,183 and $37,145, for the years ended December 31, 2021, 2020 and 2019, respectively. 4. LEASES The Company leases certain operating equipment and office facilities under long-term operating leases expiring at various dates through 2030. Leases with an initial term greater than twelve months are recorded on the Company’s balance sheet as an operating lease asset and operating lease liability and are measured at the present value of lease payments over the lease term. Substantially all of the Company’s leases are classified as operating leases. Leases with an initial term of twelve months or less with purchase options or extension options that are not reasonably certain to be exercised are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. 72 The equipment leases contain renewal or purchase options that specify prices at the then fair value upon the expiration of the lease terms. The leases also contain default provisions that are triggered by an acceleration of debt maturity under the terms of the Company’s Amended Credit Agreement, or, in certain instances, cross default to other equipment leases and certain lease arrangements require that the Company maintain certain financial ratios comparable to those required by its Amended Credit Agreement. Additionally, the leases typically contain provisions whereby the Company indemnifies the lessors for the tax treatment attributable to such leases based on the tax rules in place at lease inception. The tax indemnifications do not have a contractual dollar limit. To date, no lessors have asserted any claims against the Company under these tax indemnification provisions. The exercise of lease renewal options is at the Company’s sole discretion and is considered in the measurement of operating lease assets and operating lease liabilities when it is reasonably certain the Company will exercise the option. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease costs The Company’s lease costs are recorded in costs of contract revenues and general and administrative expenses. For the years ended December 31, 2021,2020 and 2019, respectively, lease costs are as follows: Operating lease costs Short-term lease costs Total lease cost Lease terms and commitments 2021 2020 2019 $ 24,427 95,957 $ 24,602 87,534 $27,259 70,382 $120,384 $112,136 $97,641 As recorded on the balance sheet, the Company’s maturity analysis of its operating lease liabilities as of December 31, 2021 is as follows: 2022 2023 2024 2025 2026 Thereafter Minimum lease payments Imputed interest Present value of minimum operating lease payments $18,982 17,090 14,320 7,984 4,664 6,181 69,221 6,506 $62,715 As most of the Company’s leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Additional information related to the Company’s leases as of December 31, 2021 and 2020, respectively, is as follows: Weighted average remaining lease term Weighted average discount rate 2021 2020 2019 4.4 years 4.1 years 4.2 years 5.1% 6.2% 6.7% 73 Supplemental information related to leases during the year ended December 31, 2021 and 2020, respectively, is as follows: Operating cash flows from operating leases Operating lease liabilities arising from obtaining new $(22,591) $ 24,191 $(25,064) $ 22,746 $(27,235) $ 13,149 2021 2020 2019 operating lease assets 5. ACCRUED EXPENSES Accrued expenses at December 31, 2021 and 2020 were as follows: Payroll and employee benefits Insurance Other Income and other taxes Interest Contract reserves Total accrued expenses 6. LONG-TERM DEBT Long-term debt at December 31, 2021 and 2020 were as follows: Revolving credit facility 2029 Notes 8% Notes Total Credit agreement 2021 2020 $13,533 12,821 6,427 2,941 1,460 444 $21,675 14,754 8,530 2,164 3,285 2,491 $37,626 $52,899 2021 2020 $ — 320,971 — $ — — 323,735 $320,971 $323,735 On May 3, 2019, the Company, Great Lakes Dredge & Dock Company, LLC, NASDI Holdings, LLC, Great Lakes Dredge & Dock Environmental, Inc., Great Lakes Environmental & Infrastructure Solutions, LLC, Great Lakes U.S. Fleet Management, LLC, and Drews Services LLC (collectively, the “Credit Parties”) entered into an amended and restated revolving credit and security agreement (as amended, supplemented or otherwise modified from time to time, the “Amended Credit Agreement”) with certain financial institutions from time to time party thereto as lenders, PNC Bank, National Association, as Agent (the “Agent”), PNC Capital Markets, CIBC Bank USA, Suntrust Robinson Humphrey, Inc. and Bank of America, N.A., as Joint Lead Arrangers and Joint Bookrunners, and HSBC USA, N.A., as Documentation Agent. The Amended Credit Agreement amends and restates the prior Revolving Credit and Security Agreement dated as of December 30, 2016 (as amended, the “Prior Credit Agreement”) by and among the financial institutions from time to time party thereto as lenders, the Agent and the Credit Parties party thereto, such that the terms and conditions of the Prior Credit Agreement have been subsumed and replaced in their entirety by the terms and conditions of the Amended Credit Agreement, including the amount available under the revolving credit facility. The Amended Credit Agreement matures on May 3, 2024. The terms of the Amended Credit Agreement are summarized below. The Amended Credit Agreement provides for a senior secured revolving credit facility in an aggregate principal amount of up to $200,000 of which the full amount is available for the issuance of standby letters of 74 credit. The maximum borrowing capacity under the Amended Credit Agreement is determined by a formula and may fluctuate depending on the value of the collateral included in such formula at the time of determination. The Amended Credit Agreement also includes an increase option that will allow the Company to increase the senior secured revolving credit facility by an aggregate principal amount of up to $100,000. This increase is subject to lenders providing incremental commitments for such increase, the Credit Parties having adequate borrowing capacity and provided that no default or event of default exists both before and after giving effect to such incremental commitment increase. The Amended Credit Agreement contains customary representations and affirmative and negative covenants, including a springing financial covenant that requires the Credit Parties to maintain a fixed charge coverage ratio (ratio of earnings before income taxes, depreciation and amortization, net interest expenses, non-cash charges and losses and certain other non-recurring charges, minus capital expenditures, income and franchise taxes, to net cash interest expense plus scheduled cash principal payments with respect to debt plus restricted payments paid in cash) of not less than 1.10 to 1.00. The Amended Credit Agreement also contains customary events of default (including non-payment of principal or interest on any material debt and breaches of covenants) as well as events of default relating to certain actions by the Company’s surety bonding providers. The obligations of the Credit Parties under the Amended Credit Agreement will be unconditionally guaranteed, on a joint and several basis, by each existing and subsequently acquired or formed material direct and indirect domestic subsidiary of the Company. Borrowings under the Amended Credit Agreement will be used to pay fees and expenses related to the Amended Credit Agreement, finance acquisitions permitted under the Amended Credit Agreement, finance ongoing working capital and for other general corporate purposes. The obligations under the Amended Credit Agreement are secured by substantially all of the assets of the Credit Parties. The outstanding obligations thereunder shall be secured by a valid first priority perfected lien on substantially all of the U.S. flagged and located vessels of the Credit Parties and a valid perfected lien on all domestic accounts receivable and substantially all other assets of the Credit Parties, subject to the permitted liens and interests of other parties (including the Company’s surety bonding providers). Interest on the senior secured revolving credit facility of the Amended Credit Agreement is equal to either a Domestic Rate option or LIBOR option, at the Company’s election. As of the Closing Date, (a) the Domestic Rate option is the highest of (1) the base commercial lending rate of PNC Bank, National Association, as publicly announced, (2) the sum of the federal funds open rate plus 0.5% and (3) the sum of the daily LIBOR rate plus 1.0%, so long as a daily LIBOR rate is offered, ascertainable and not unlawful plus an interest margin of 0.5%; and (b) the LIBOR Rate option is the rate that applies for the applicable interest period on the Bloomberg page BBAMI (or such other substitute page or alternate source as agreed) plus an interest margin of 1.5%. After the date on which a borrowing base certificate is required to be delivered under Section 9.2 of the Amended Credit Agreement (commencing with the fiscal quarter ended September 30, 2019, the “Adjustment Date”), the Domestic Rate option will be the Domestic Rate plus an interest margin ranging between 0.5% and 1.0% and the LIBOR Rate option will be the LIBOR Rate plus an interest margin ranging between 1.5% and 2.0%, in each case, depending on the quarterly average undrawn availability on the Amended Credit Agreement. The Company had no borrowings on the revolver, $25,127 and $36,407 of letters of credit outstanding and $174,546 and $163,231 of availability under the Amended Credit Agreement as of December 31, 2021 and 2020, respectively. The availability under the Amended Credit Agreement is suppressed by $327 and $362 as of December 31, 2021 and 2020, respectively, as a result of certain limitations set forth in the Amended Credit Agreement. Senior notes and subsidiary guarantors In May 2021 the Company sold $325,000 of unsecured 5.25% Senior Notes (the “2029 Notes”) pursuant to a private offering. The 2029 Notes were priced to investors at par and will mature on June 1, 2029. The Company used the net proceeds from the offering, together with cash on hand, to redeem all $325,000 aggregate principal 75 amount of its outstanding 8.000% Senior Notes due 2022 (the “8% Notes”). Approximately $1,000 of deferred financing fees related to the 8% Notes were extinguished and are presented within year-to-date net interest expense in the Statement of Operations. The Company’s obligations under these 2029 Notes are guaranteed by certain of the Company’s 100% owned domestic subsidiaries. Such guarantees are full, unconditional and joint and several. The parent company issuer has no independent assets or operations and all non-guarantor subsidiaries have been determined to be minor. Other The scheduled principal payments through the maturity date of the Company’s long-term debt at December 31, 2021, are as follows: Years Ending December 31, 2022 2023 2024 2025 2026 Thereafter Total $ — — — — — 325,000 $325,000 The Company incurred amortization of deferred financing fees for its long-term debt of $1,382, $1,611 and $2,231 for each of the years ended December 31, 2021, 2020 and 2019. Such amortization is recorded as a component of net interest expense. 7. FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value hierarchy has been established by GAAP that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance describes three levels of inputs that may be used to measure fair value: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. At times, the Company holds certain derivative contracts that it uses to 76 manage foreign currency risk or commodity price risk. The Company does not hold or issue derivatives for speculative or trading purposes. The fair values of these financial instruments are summarized as follows: Description At December 31, 2021 Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fuel hedge contracts $ 630 $— $ 630 $— Description At December 31, 2020 Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fuel hedge contracts $1,739 $— $1,739 $— Fuel hedge contracts The Company is exposed to certain market risks, primarily commodity price risk as it relates to the diesel fuel purchase requirements, which occur in the normal course of business. The Company enters into heating oil commodity swap contracts to hedge the risk that fluctuations in diesel fuel prices will have an adverse impact on cash flows associated with its domestic dredging contracts. The Company’s goal is to hedge approximately 80% of the eligible fuel requirements for work in domestic backlog. As of December 31, 2021, the Company was party to various swap arrangements to hedge the price of a portion of its diesel fuel purchase requirements for work in its backlog to be performed through December 2022. As of December 31, 2021, there were 10.2 million gallons remaining on these contracts which represent approximately 80% of the Company’s forecasted domestic fuel purchases through December 2022. Under these swap agreements, the Company will pay fixed prices ranging from $1.25 to $2.46 per gallon. At December 31, 2021 and 2020, the fair value asset of the fuel hedge contracts were estimated to be $630 and $1,739, respectively, and are recorded in other current assets. For fuel hedge contracts considered to be highly effective, the gains reclassified to earnings from changes in fair value of derivatives, net of cash settlements and taxes, for the year ended December 31, 2021 were $6,481. The remaining gains and losses included in the accumulated other comprehensive income at December 31, 2021 will be reclassified into earnings over the next twelve months, corresponding to the period during which the hedged fuel is expected to be utilized. Changes in the fair value of fuel hedge contracts not considered highly effective are recorded as costs of contract revenues in the Statement of Operations. The fair value of fuel hedges are corroborated using inputs that are readily observable in public markets; therefore, the Company determines fair values of these fuel hedges using Level 2 inputs. The Company is exposed to counterparty credit risk associated with non-performance of its various derivative instruments. The Company’s risk would be limited to any unrealized gains on current positions. To help mitigate this risk, the Company transacts only with counterparties that are rated as investment grade or higher. In addition, all counterparties are monitored on a continuous basis. 77 The fair value of the fuel hedge contracts outstanding as of December 31, 2021 and 2020 is as follows: Asset derivatives: Derivatives designated as hedging instruments Fuel hedge contracts Other current assets $630 $1,739 Balance Sheet Location Fair Value at December 31, 2021 2020 Assets and liabilities measured at fair value on a nonrecurring basis All other nonfinancial assets and liabilities measured at fair value in the financial statements on a nonrecurring basis are subject to fair value measurements and disclosures. Nonfinancial assets and liabilities included in the consolidated balance sheets and measured on a nonrecurring basis consist of goodwill and long- lived assets. Goodwill and long-lived assets are measured at fair value to test for and measure impairment, if any, at least annually for goodwill or when necessary for both goodwill and long-lived assets. Accumulated other comprehensive income (loss) Changes in the components of the accumulated balances of other comprehensive income (loss) are as follows: Cumulative translation adjustments—net of tax Derivatives: Reclassification of derivative (gains) losses to earnings—net of tax Change in fair value of derivatives—net of tax Net unrealized (gain) loss on derivatives—net of tax Total other comprehensive income (loss) $ (828) $ 2021 2020 $ — $ — 2019 $ — (6,481) 5,653 (828) 5,825 (5,152) 673 673 1,458 2,646 4,104 $4,104 Adjustments reclassified from accumulated balances of other comprehensive income (loss) to earnings are as follows: Derivatives: Fuel hedge contracts Other financial instruments Statement of Operations Location 2021 2020 2019 Costs of contract revenues Income tax (provision) benefit $(8,670) (2,189) $7,703 1,878 $1,975 517 $(6,481) $5,825 $1,458 The carrying value of financial instruments included in current assets and current liabilities approximates fair value due to the short-term maturities of these instruments. Based on timing of the cash flows and comparison to current market interest rates, the carrying value of the senior revolving credit agreement approximates fair value. In May 2021, the Company sold $325,000 of the 2029 Notes pursuant to a private offering, which were outstanding at December 31, 2021 (See Note 6, Long-Term Debt). The 2029 Notes were priced to investors at par and will mature on June 1, 2029. The 2029 Notes are senior unsecured obligations of the Company and its subsidiaries that guarantee the 2029 Notes. The fair value of the 2029 Notes was $334,750 at December 31, 2021, which is a Level 1 fair value measurement as the senior notes value was obtained using 78 quoted prices in active markets. It is impracticable to determine the fair value of outstanding letters of credit or performance, bid and payment bonds due to uncertainties as to the amount and timing of future obligations, if any. 8. INCOME TAXES The Company’s income tax provision (benefit) from continuing and discontinued operations for the years ended December 31, 2021, 2020 and 2019 are as follows: Income tax provision from continuing operations Income tax benefit from discontinued operations Income tax provision 2021 2020 2019 $13,391 — $20,187 — $15,253 (4,556) $13,391 $20,187 $10,697 The Company’s income (loss) from continuing operations before income tax from domestic and foreign continuing operations for the years ended December 31, 2021, 2020 and 2019 is as follows: Domestic operations Foreign operations 2021 2020 2019 $65,708 (2,885) 94,826 (8,536) $ 89,344 (18,423) Total income from continuing operations before income tax $62,823 $86,290 $ 70,921 The provision for income taxes from continuing operations as of December 31, 2021, 2020 and 2019 is as follows: Federal: Current Deferred State: Current Deferred Foreign: Current Deferred Total 2021 2020 2019 $ — 11,020 $ — 17,464 $ — 14,052 1,080 1,291 — — 128 3,023 (428) — 212 989 — — $13,391 $20,187 $15,253 79 The Company’s income tax provision from continuing operations reconciles to the provision at the statutory U.S. federal income tax rate of 21% for the years ended December 31, 2021, 2020 and 2019, as follows: Tax provision at statutory U.S. federal income tax rate State income tax — net of federal income tax benefit Adjustment to deferred tax depreciation Change in deferred state tax rate Stock based compensation Nondeductible officer compensation Research and development tax credits Changes in unrecognized tax benefits Changes in valuation allowance Other Income tax provision 2021 2020 2019 $13,193 2,144 (1,414) — (1,318) 1,195 (642) — — 233 $18,121 3,124 — — (1,212) 1,212 (674) — — (384) $14,893 3,049 — (1,835) (1,266) 1,021 (452) (56) (3) (98) $13,391 $20,187 $15,253 At December 31, 2021 and 2020, the Company had loss carryforwards for federal income tax purposes of $55,554 and $92,328 respectively, which expire in 2037. At December 31, 2021 and 2020, the Company had gross net operating loss carryforwards for state income tax purposes totaling $157,245 and $170,738, respectively, which expire between 2023 and 2039. The Company has established a valuation allowance that was $1,623 and $1,628 as of December 31, 2021 and 2020, respectively. The Company believes that the remaining net operating losses, net of the valuation allowance, will be fully utilized in future periods. The Company also has foreign gross net operating loss carryforwards of approximately $2,469 and $2,414 as of December 31, 2021 and 2020, of which expire between 2022 and 2028. At December 31, 2021 and 2020, a full valuation allowance has been established for the deferred tax asset of $864 and $845 related to foreign net operating loss carryforwards, respectively, as the Company believes it is more likely than not that the net operating loss carryforwards will not be realized. The Company does not expect that total unrecognized tax benefits will significantly increase or decrease within the next 12 months. Below is a tabular reconciliation of the total amounts of unrecognized tax benefits at the beginning and end of each period. Unrecognized tax benefits — January 1 Gross increases — tax positions in prior period Gross increases — current period tax positions Gross decreases — expirations Gross decreases — tax positions in prior period Unrecognized tax benefits — December 31, 2021 2020 2019 $— — — — — $— $— — — — — $— $ 157 — — — (157) $ — The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. As of December 31, 2021, 2020 and 2019 the Company had no interest and penalties recorded. The Company files income tax returns at the U.S. federal level and in various state and foreign jurisdictions. U.S. federal income tax years prior to 2018 are closed and no longer subject to examination. With few exceptions, the statute of limitations in state taxing jurisdictions in which the Company operates has expired for all years prior to 2017. In foreign jurisdictions in which the Company operates, years prior to 2016 are closed and are no longer subject to examination. 80 The Company’s deferred tax assets (liabilities) at December 31, 2021 and 2020 are as follows: Deferred tax assets: Operating lease assets Accrued liabilities Federal NOLs Foreign NOLs State NOLs Tax credit carryforwards Valuation allowance Total deferred tax assets Deferred tax liabilities: Depreciation and amortization Operating lease liabilities Other liabilities Total deferred tax liabilities Net noncurrent deferred tax liabilities 2021 2020 $ 15,835 7,130 11,666 864 6,682 3,892 (2,487) $ 16,501 8,212 19,389 845 7,256 3,250 (2,473) 43,582 52,980 (96,207) (15,713) (159) (92,547) (16,460) (439) (112,079) (109,446) $ (68,497) $ (56,466) Deferred tax assets relate primarily to reserves and other liabilities for costs and expenses not currently deductible for tax purposes as well as net operating loss and other carryforwards. Deferred tax liabilities relate primarily to the cumulative difference between book depreciation and amounts deducted for tax purposes. The Company evaluates its ability to realize deferred tax assets by considering all available positive and negative evidence. This evidence includes its cumulative earnings or losses in recent years. The Company further considers the impact on these cumulative earnings or losses of discontinued operations and other divested operations and joint ventures, restructuring charges and other nonrecurring adjustments that are not indicative of its ability to generate taxable income in future periods. The Company also considers sources of taxable income, such as the amount and timing of realization of its deferred tax liabilities relative to the timing of expiration of loss carryforwards. When it is estimated to be more likely than not that all or some portion of deferred tax assets will not be realized, the Company establishes a valuation allowance for the amount of such deferred tax assets considered to be unrealizable. After evaluating the positive and negative evidence for future realization of deferred tax assets, the Company recorded valuation allowances for foreign net operating loss carryforwards and certain state net operating loss carryforwards to reduce the balance of these deferred tax assets at December 31, 2021 and 2020 as it was more likely than not that the balance of these tax items would not be realized. By contrast, after evaluating the positive and negative evidence, the Company concluded that it was more likely than not that the deferred federal income tax asset and remaining state net operating loss carryforwards recorded at December 31, 2021 and 2020 would ultimately be realized and determined that no valuation allowance was required. 9. SHARE-BASED COMPENSATION On May 5, 2021, the Company’s stockholders approved the Great Lakes Dredge & Dock Corporation 2021 Long-Term Incentive Plan (the “Incentive Plan”), which previously had been approved by the Company’s board of directors subject to stockholder approval. The Incentive Plan replaces the 2017 Long-Term Incentive Plan (the “Prior Plan”) and is largely based on the Prior Plan, but with updates to the available shares and other administrative changes. The Incentive Plan permits the granting of stock options, stock appreciation rights, restricted stock and restricted stock units to the Company’s employees and directors for up to 1.5 million shares of common stock, plus the number of shares that remained available for future grant under the Prior Plan as of the effectiveness of the Incentive Plan. 81 The Prior Plan permitted the granting of stock options, stock appreciation rights, restricted stock and restricted stock units to its employees and directors for up to 3.3 million shares of common stock, plus an additional 1.7 million shares underlying equity awards issued under the 2007 Long-Term Incentive Plan. The Company may also issue share-based compensation as inducement awards to new employees upon approval of the Board of Directors. Compensation cost charged to expense related to share-based compensation arrangements was $5,188, $6,754 and $6,908, for the years ended December 31, 2021, 2020 and 2019, respectively. Non-qualified stock options The NQSO awards were granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. The option awards generally vest in three equal annual installments commencing on the first anniversary of the grant date, and have ten year exercise periods. The fair value of the NQSOs was determined at the grant date using a Black-Scholes option pricing model, which requires the Company to make several assumptions. The risk-free interest rate is based on the U.S. Treasury yield curve in effect for the expected term of the option at the time of grant. The annual dividend yield on the Company’s common stock is based on estimates of future dividends during the expected term of the NQSOs. The expected life of the NQSOs was determined from historical exercise data providing a reasonable basis upon which to estimate the expected life. The volatility assumptions were based on historical volatility of Great Lakes. There is not an active market for options on the Company’s common stock and, as such, implied volatility for the Company’s stock was not considered. Additionally, the Company’s general policy is to issue new shares of registered common stock to satisfy stock option exercises or grants of restricted stock. No NQSO awards were granted in 2021, 2020 and 2019. The aggregate intrinsic value of stock options represents the difference between market value on the date of exercise and the option price. The aggregate intrinsic value of stock options exercised during 2021, 2020 and 2019 was $1,351, $779 and $2,534, respectively. A summary of stock option activity under the Incentive Plan as of December 31, 2021, and changes during the year ended December 31, 2021, is presented below: Options Outstanding as of January 1, 2021 Granted Exercised Forfeited or Expired Outstanding as of December 31, 2021 Vested at December 31, 2021 Shares 278 — (173) — 105 105 Restricted stock units Weighted Average Exercise Price Weighted-Average Remaining Contract Term (yrs) Aggregate Intrinsic Value ($000’s) $7.02 — 6.73 — $7.50 $7.50 1.9 1.9 $860 $860 RSUs primarily vest in equal portions over the three year vesting period. The fair value of RSUs was based upon the Company’s stock price on the date of grant. A summary of the status of the Company’s non-vested RSUs as of December 31, 2021, and changes during the year ended December 31, 2021, is presented below: Nonvested Restricted Stock Units Outstanding as of January 1, 2021 Granted Vested Forfeited Outstanding as of December 31, 2021 Expected to vest at December 31, 2021 Shares 1,407 327 (653) (34) 1,047 846 Weighted-Average Grant- Date Fair Value $ 8.00 14.66 7.00 7.69 $10.57 $10.55 82 As of December 31, 2021, there was $3,959 of total unrecognized compensation cost related to non-vested RSUs granted under the Incentive Plan. That cost for non-vested RSUs is expected to be recognized over a weighted-average period of 1.8 years. The Incentive Plan permits the employee to use vested shares from RSUs to satisfy the grantee’s U.S. federal income tax liability resulting from the issuance of the shares through the Company’s retention of that number of common shares having a market value as of the vesting date equal to such tax obligation up to the minimum statutory withholding requirements. The amount related to shares used for such tax withholding obligations was approximately $4,250 and $4,748 for the years ended December 31, 2021 and 2020, respectively. Director compensation The Company uses a combination of cash and share-based compensation to attract and retain qualified candidates to serve on its Board of Directors. Compensation is paid to non-employee directors. Directors who are employees receive no additional compensation for services as members of the Board or any of its committees. Share-based compensation is paid pursuant to the Incentive Plan. Each non-employee director of the Company receives an annual retainer of $155, payable quarterly in arrears, and is generally paid 50% in cash and 50% in common stock or deferred restricted stock units of the Company. Directors may elect to receive some or all of the cash retainer in common stock or deferred restricted stock units. In 2021, the Chairman of the Board received an additional $100 of annual compensation, paid 100% in common stock. In the years ended December 31, 2021, 2020 and 2019, 50 thousand, 79 thousand and 78 thousand shares, respectively, of the Company’s common stock or restricted stock units were issued to non-employee directors under the Incentive Plan. 10. REVENUE The Company’s revenue is derived from contracts for services with federal, state, local and foreign governmental entities and private customers. Revenues are generally derived from the enhancement or preservation of navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Performance obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account upon which the Company’s revenue is calculated. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue as the performance obligation is satisfied. Fixed-price contracts, which comprise substantially all of the Company’s revenue, will most often represent a single performance obligation as the promise to transfer the individual services is not separately identifiable from other promises in the contracts and, therefore, not distinct. The Company’s performance obligations are satisfied over time and revenue is recognized using contract fulfillment costs incurred to date compared to total estimated costs at completion, also known as cost-to-cost, to measure progress towards completion. As the Company’s performance creates an asset that the customer controls, this method provides a faithful depiction of the transfer of an asset to the customer. Generally, the Company has an enforceable right to payment for performance completed to date. The majority of the Company’s contracts are completed in a year or less. At December 31, 2021, the Company had $551,588 of remaining performance obligations, which the Company refers to as total backlog. Approximately 88% of the Company’s backlog will be completed in 2022 with the remaining balance expected to be completed by 2023. 83 Transaction price The transaction price is calculated using the Company’s estimated costs to complete a project. These costs are based on the types of equipment required to perform the specified service, project site conditions, the estimated project duration, seasonality, location and complexity of a project. The nature of the Company’s contracts gives rise to several types of variable consideration, including pay on quantity dredged for dredging projects and dredging project contract modifications. Estimated pay quantity is the amount of material the Company expects to dredge for which it will receive payment. Estimated quantity to be dredged is calculated using engineering estimates based on current survey data and the Company’s knowledge based on historical project experience. Revenue by category Domestically, the Company’s work generally is performed in coastal waterways and deep-water ports. The U.S. dredging market consists of four primary types of work: capital, coastal protection, maintenance and rivers & lakes. Foreign projects typically involve capital work. The following table sets forth, by type of work, the Company’s contract revenues for the years ended December 31, 2021, 2020 and 2019: Revenues Capital—U.S. Capital—foreign Coastal protection Maintenance Rivers & lakes Total revenues 2021 2020 2019 $397,034 6,596 169,678 132,551 20,290 $336,163 25,892 201,361 148,767 21,418 $299,706 48,619 182,369 104,753 76,071 $726,149 $733,601 $711,518 The following table sets forth, by type of customer, the Company’s contract revenues for the years ended December 31, 2021, 2020 and 2019: Revenues Federal government State and local government Private Foreign Total revenues 2021 2020 2019 $568,980 118,712 31,861 6,596 $582,949 85,737 39,023 25,892 $581,157 71,398 10,344 48,619 $726,149 $733,601 $711,518 Contract balances Billings on contracts are generally submitted after verification with the customers of physical progress and are recognized as accounts receivable in the balance sheet. For billings that do not match the timing of revenue recognition, the difference between amounts billed and recognized as revenue is reflected in the balance sheet as either contract revenues in excess of billings or billings in excess of contract revenues. Certain pre-contract and pre-construction costs are capitalized and reflected as contract assets in the balance sheet. Customer advances, deposits and commissions are reflected in the balance sheet as contract liabilities. 84 Accounts receivable at December 31, 2021 and December 31, 2020 are as follows: Completed contracts Contracts in progress Retainage Allowance for doubtful accounts Total accounts receivable—net 2021 2020 $10,612 65,415 7,490 $12,347 21,239 5,968 83,517 (564) 39,554 (564) $82,953 $38,990 The components of contracts in progress at December 31, 2021 and December 31, 2020 are as follows: Costs and earnings in excess of billings: Costs and earnings for contracts in progress Amounts billed 2021 2020 $ 270,998 (240,941) $ 199,964 (168,569) Costs and earnings in excess of billings for contracts in progress Costs and earnings in excess of billings for completed contracts 30,057 10,894 31,395 2,823 Total contract revenues in excess of billings Current portion of contract revenues in excess of billings Long-term contract revenues in excess of billings Total contract revenues in excess of billings Billings in excess of costs and earnings: Amounts billed Costs and earnings for contracts in progress Total billings in excess of contract revenues $ 40,951 $ 34,218 $ 39,844 1,107 $ 32,106 2,112 $ 40,951 $ 34,218 $(224,381) 209,567 $(550,468) 517,860 $ (14,814) $ (32,608) At December 31, 2021 and 2020, costs to fulfill contracts with customers recognized as an asset were $5,652 and $10,501, respectively, and are recorded in other current assets and other noncurrent assets. These costs relate to pre-contract and pre-construction activities. During the years ended December 31, 2021 and 2020 the company amortized pre-contract and pre-construction costs of $17,839 and $15,541, respectively. The Company’s largest domestic customer is the U.S. Army Corps of Engineers (the “Corps”), which has responsibility for federally funded projects related to navigation and flood control of U.S. waterways. In 2021, 2020 and 2019, 78.4%, 79.5% and 81.7%, respectively, of contract revenues were earned from contracts with federal government agencies, including the Corps, as well as other federal entities such as the U.S. Coast Guard and U.S. Navy. During the year ended December 31, 2021 and 2020, respectively, the Company recognized $716 and $616 of revenue related to the use of equipment by a customer working on a federal government contract. At December 31, 2021 and 2020, approximately 68.5% and 42.6% respectively, of accounts receivable, including contract revenues in excess of billings and retainage, were due on contracts with federal government agencies. The Company depends on its ability to continue to obtain federal government contracts, and indirectly, on the amount of federal funding for new and current government dredging projects. Therefore, the Company’s operations can be influenced by the level and timing of federal funding. 85 The Company derived revenues and gross profit (loss) from foreign project operations for the years ended December 31, 2021, 2020, and 2019, as follows: Contract revenues Costs of contract revenues Gross profit (loss) 2021 2020 2019 $ 6,596 (9,281) $ 25,892 (34,529) $ 48,619 (66,347) $(2,685) $ (8,637) $(17,728) In 2021, 2020 and 2019, foreign revenues were primarily from work done in the Middle East. The majority of the Company’s long-lived assets are marine vessels and related equipment. At any point in time, the Company may employ certain assets outside of the U.S., as needed, to perform work on the Company’s foreign projects. As of December 31, 2021, long-lived assets located outside of the U.S had no net book value compared to $5,225 at December 31, 2020. Currently our assets outside of the U.S. do not include dredges. Revenue from foreign projects has been concentrated in the Middle East which comprised less than 10% in 2021, 2020 and 2019. At December 31, 2021 and 2020, approximately 9% and 12%, respectively, of total accounts receivable, including retainage and contract revenues in excess of billings, were due on contracts in the Middle East. 11. RETIREMENT PLANS The Company sponsors two 401(k) savings plans, one covering substantially all non-union salaried employees (“Salaried Plan”), a second covering its hourly employees (“Hourly Plan”). Under the Salaried Plan and the Hourly Plan, individual employees may contribute a percentage of compensation and the Company will match a portion of the employees’ contributions. The Salaried Plan also includes a discretionary profit-sharing component, permitting the Company to make discretionary employer contributions to all eligible employees of these plans. Additionally, the Company sponsors a Supplemental Savings Plan in which the Company makes contributions for certain key executives. The Company’s expense for matching, discretionary and Supplemental Savings Plan contributions for 2021, 2020 and 2019, was $4,659, $5,557 and $5,168, respectively. The Company also contributes to various multiemployer pension plans pursuant to collective bargaining agreements. In 2021, 2020 and 2019, the Company contributed $4,632, $4,929 and $4,517 respectively to all of the multiemployer plans that provide pension benefits in its continuing operations. The information available to the Company about the multiemployer plans in which it participates, whether via request to the plan or publicly available, is generally dated due to the nature of the reporting cycle of multiemployer plans and legal requirements under the Employee Retirement Income Security Act (“ERISA”) as amended by the Multiemployer Pension Plan Amendments Act (“MPPAA”). Based upon these plans’ most recently available annual reports, the Company’s contributions to these plans were less than 5% of each plan’s total contributions. The Company does not expect any future increased contributions to have a material negative impact on its financial position, results of operations or cash flows for future years. The risks of participating in multiemployer plans are different from single employer plans as assets contributed are available to provide benefits to employees of other employers and unfunded obligations from an employer that discontinues contributions are the responsibility of all remaining employers. In addition, in the event of a plan’s termination or the Company’s withdrawal from a plan, the Company may be liable for a portion of the plan’s unfunded vested benefits. However, information from the plans’ administrators is not available to permit the Company to determine its share, if any, of unfunded vested benefits. 12. COMMITMENTS AND CONTINGENCIES Commercial commitments Performance and bid bonds are customarily required for dredging and marine construction projects. The Company has bonding agreements with Argonaut Insurance Company, Berkley Insurance Company, Chubb 86 Surety and Liberty Mutual Insurance Company under which the Company can obtain performance, bid and payment bonds. The Company also has outstanding bonds with Travelers Casualty and Surety Company of America and Zurich American Insurance Company (“Zurich”). Bid bonds are generally obtained for a percentage of bid value and amounts outstanding typically range from $1,000 to $10,000. At December 31, 2021, the Company had outstanding performance bonds with a notional amount of approximately $1,164,822. The revenue value remaining in backlog related to the projects of continuing operations totaled approximately $551,588. Certain foreign projects performed by the Company have warranty periods, typically spanning no more than one to three years beyond project completion, whereby the Company retains responsibility to maintain the project site to certain specifications during the warranty period. Generally, any potential liability of the Company is mitigated by insurance, shared responsibilities with consortium partners, and/or recourse to owner-provided specifications. Legal proceedings and other contingencies As is customary with negotiated contracts and modifications or claims to competitively bid contracts with the federal government, the government has the right to audit the books and records of the Company to ensure compliance with such contracts, modifications, or claims, and the applicable federal laws. The government has the ability to seek a price adjustment based on the results of such audit. Any such audits have not had, and are not expected to have, a material impact on the financial position, operations, or cash flows of the Company. Various legal actions, claims, assessments and other contingencies arising in the ordinary course of business are pending against the Company and certain of its subsidiaries. The Company will defend itself vigorously on all matters. These matters are subject to many uncertainties, and it is possible that some of these matters could ultimately be decided, resolved, or settled adversely to the Company. Although the Company is subject to various claims and legal actions that arise in the ordinary course of business, except as described below, the Company is not currently a party to any material legal proceedings or environmental claims. The Company records an accrual when it is probable a liability has been incurred and the amount of loss can be reasonably estimated. The Company does not believe any of these proceedings, individually or in the aggregate, would be expected to have a material effect on results of operations, cash flows or financial condition. On April 23, 2014, the Company completed the sale of NASDI, LLC (“NASDI”) and Yankee Environmental Services, LLC (“Yankee”), which together comprised the Company’s historical demolition business, to a privately-owned demolition company. On January 14, 2015, the Company and its subsidiary, NASDI Holdings, LLC, brought an action in the Delaware Court of Chancery to enforce the terms of the Company’s agreement to sell NASDI and Yankee. Under the terms of the agreement, the Company received cash of $5,309 and retained the right to receive additional proceeds based upon future collections of outstanding accounts receivable and work in process existing at the date of close. The Company seeks specific performance of the buyer’s obligation to collect and to remit the additional proceeds, and other related relief. Defendants have filed counterclaims alleging that the Company misrepresented the quality of its contracts and receivables prior to the sale. The Company denies defendants’ allegations. In addition, the Company has been granted a judgment in the amount of $21,934 based upon the buyer’s default of its obligations to indemnify the Company for losses resulting from failure to perform in accordance with terms of surety performance bond. The defendants filed a notice of appeal from that judgement. The Company continues to aggressively pursue collection from the buyer on outstanding amounts owed under the sale and the indemnification. An estimate of a range of potential gains or losses relating to these matters cannot reasonably be made. On April 22, 2021, the U.S. Attorney’s Office for the Eastern District of Louisiana filed a bill of information against the Company charging the Company with a negligent discharge violation of the Clean Water Act arising from a September 2016 oil spill. The spill occurred during the Company’s Cheniere Ronquille project and resulted in the discharge of around one hundred sixty barrels of crude oil in Bay Long, Louisiana. The Company has cooperated with the U.S. Attorney’s Office and other relevant agencies in their investigation of the oil spill 87 and on June 15, 2021, the Company pleaded guilty to the misdemeanor violation alleged in the bill of information and agreed to pay a fine of $1,000. In the first quarter of 2022, the Company entered into a settlement of a civil suit arising from the same matter. The Company remains subject to potential liability for restitution in connection with this criminal matter, and has deposited the potential liability for the criminal matter of $2,000 into the registry of the court. That amount is presented as restricted cash in other noncurrent assets. As a result of the pending conviction, the government will likely initiate statutory debarment proceedings against the Company, which might prohibit the Company from bidding for, entering into or completing certain government projects. Although the Company does not know whether debarment proceedings will result in prohibitions, or the impact of any such resulting prohibitions, the Company does not expect any such proceedings or prohibitions to cause a material disruption to its business, financial condition or results of operations. On September 27, 2019, the EPA Region 4 filed an administrative complaint against the Company relating to a project the Company performed at PortMiami from 2013-2015 alleging violations of Section 103 of the Marine Protection, Research, and Sanctuaries Act (“MPRSA”) and failure to report violations of the MPRSA. In July 2021, the parties executed a consent agreement and the Company paid $500 as a civil penalty in August 2021. 13. BUSINESS DISPOSITIONS Discontinued operations During the second quarter of 2019, the Company completed the sale of the historical environmental & infrastructure business. Under the terms of the agreement, the Company received cash of $17,500 in the second quarter of 2019 and received an additional $857 in the third quarter of 2019. The results of the business have been reported in discontinued operations as follows: Revenue Loss before income taxes from discontinued operations Loss on disposal of assets held for sale Income tax benefit Loss from discontinued operations, net of income taxes 2019 $25,040 $ (8,253) (2,632) 4,556 $ (6,329) 88 Great Lakes Dredge & Dock Corporation Schedule II—Valuation and Qualifying Accounts For the Years Ended December 31, 2021, 2020 and 2019 (In thousands) Description Year ended December 31, 2019 Allowances deducted from assets to which they apply: Allowances for doubtful accounts Valuation allowance for deferred tax assets Total Year ended December 31, 2020 Allowances deducted from assets to which they apply: Allowances for doubtful accounts Valuation allowance for deferred tax assets Total Year ended December 31, 2021 Allowances deducted from assets to which they apply: Allowances for doubtful accounts Valuation allowance for deferred tax assets Total Beginning Balance Additions Deductions Ending balance $ 200 4,786 $4,986 $364 — $364 $ — $ 564 3,495 (1,291) $(1,291) $4,059 $ 564 3,495 $4,059 $— — $— $ — $ 564 2,473 (1,022) $(1,022) $3,037 $ 564 2,473 $3,037 $— 14 $ 14 $ — $ 564 2,487 — $ — $3,051 89 Number 2.1 2.2 3.1 3.2 3.3 4.1 4.2 4.3 4.4 10.1 10.2 I.
