Services Provided

Marine Construction Services

Marine construction services include construction, restoration, dredging, maintenance and repair of marine transportation facilities, marine pipelines, bridges and causeways, and marine environmental structures. We have the capability of providing design-build services and typically serve as the prime contractor for these types of projects.

Marine transportation facility projects include building or rehabilitating public port facilities for container ship loading and unloading; cruise ship port facilities; private terminals; special-use Navy terminals; recreational use marinas and docks; and other marine-based facilities. These projects typically require the positioning and installation of steel or

Table of Contents

concrete fabrication dock or mooring structures designed for durability and longevity, and involve driving piles of concrete, pipe or sheet pile to provide a foundation for the port facility structure that we subsequently construct on the piles. We also provide on-going maintenance and repair, inspection services, emergency repair, and demolition and salvage services to such facilities.

Our marine pipeline service projects generally include the installation and removal of underwater buried pipeline transmission lines; installation of pipeline intakes and outfalls for industrial facilities; construction of pipeline outfalls for wastewater and industrial discharges; river crossing and directional drilling; creation of hot taps and tie-ins; and inspection, maintenance and repair services.

Our bridge and causeway projects include the construction, repair and maintenance of all types of overwater bridges and causeways, as well as the development of fendering systems in marine environments. We serve as the prime contractor for many of these projects, and some of these are design-build contracts. These projects involve fabricating steel or concrete structures designed for durability and longevity, and involve driving concrete, pipe or sheet pile into the subsurface to create support for the concrete deck roadways that we subsequently construct on the piles. These piles can exceed four feet in diameter, can range up to 170 feet in overall length, and are often driven 90 feet into the sea or river floor. We do not control the funding of bridge and causeway work, which has not been consistently available.

Marine environmental structure projects may include the installation of concrete mattresses to promote erosion protection; construction of levees to contain environmental mitigation projects, and the installation of geotubes for wetlands and island creation. Such structures are used for erosion control, wetlands creation and environmental remediation.

Dredging generally enhances or preserves the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Dredging involves the removal of mud and silt from the channel floor by means of a mechanical backhoe, crane and bucket or cutter suction dredge and pipeline systems. Dredging is integral to marine capital and maintenance projects, including: maintenance for previously deepened waterways and harbors to remove silt, sand and other accumulated sediments; construction of breakwaters, jetties, canals and other marine structures; deepening ship channels and wharves to accommodate larger and deeper draft ships; containing erosion of wetlands and coastal marshes; land reclamation; and beach nourishment and creation of wildlife refuges. Maintenance dredging projects are a source of recurring revenue as active channels typically require routine dredging due to natural sedimentation. The frequency of maintenance dredging may be accelerated by heavy rainfall or major weather events such as hurricanes. Areas where no natural deep water ports exist, such as the Texas Gulf Coast, require substantial dredging. We maintain multiple specialty dredges of various sizes and specifications to meet customer needs. Our dredging services are typically combined with our marine construction services to provide a turn-key solution for our customers.

Our specialty services include design, salvage, demolition, surveying, towing, diving and underwater inspection, excavation and repair. Our diving services are largely performed in shallow water and include inspections, salvage and pile restoration and encapsulation. Our survey services include surveying pipelines and performing hydrographic surveys which determine the configuration of the floors of bodies of water and detect and identify wrecks and other obstructions. Most of these specialty services support our other services or provide an introductory opportunity to other customers.

Concrete Construction Services

The concrete segment has earned a reputation as one of the most recognizable and reputable concrete contractors where we operate. Our success has been achieved by maintaining a focus on our clients and addressing their problems. The commercial construction arena has been our focus and we have completed thousands of successful commercial projects – both simple and complex in the broader Texas market including Houston, Dallas, Fort Worth, Austin and San Antonio. Our portfolio of commercial projects includes warehouse and distribution, medical, retail, education, office buildings, multi-family, religious, industrial and community projects – nearly the full spectrum of commercial construction projects. We are a turnkey subcontractor that performs the vast majority of all our work with our own labor forces.

Warehouse and distribution projects include large, intermediate and small facilities serving needs in nearly every commercial, private and public industry. Typically, the developer and builders construction method of choice for these projects are concrete tilt-wall structures ranging in size from a few thousand square feet to over one million square feet.

Table of Contents

Speed, efficiency and quality are keys to meeting our clients’ needs to deliver projects on or ahead of schedule. We have received awards for many of these projects.

Medical/healthcare projects always come with stringent requirements. We have the knowledge and experience to meet these high expectations. From hospitals to laboratories, including high rises and their garages, we know how to carry out construction activities in densely occupied areas with minimal disturbance to critical facilities daily operations.

We applyourconcreteexperiencetoavarietyofoffice building projecttypes,includinglow,mid-riseandhigh-riseconcretestructures, whether in downtown metropolitan cities or in business districts serving neighboring communities. We utilize different technologies for elevated concrete structures, such as high-rise concretestructures.

We have the abundant knowledge of the extensive formwork systems, cranes and equipment needed to successfully deliver multi-family projects – typically in tight spaces, whether it be podium structures, mid-rise, high-rise and luxury projects. We have earned the reputation for successfully managing and delivering multi-family projects with aggressive schedules.

We bring a breadth of knowledge and a diverse portfolio of education projects. We have completed over 20 million square feet of education projects including libraries, higher education, research facilities, athletic facilities, stadiums, elementary, middle and high schools. We have also applied our skills to state of the art performing arts facilities and studios.

Retail centers play an important role for serving our neighborhoods. They address a variety of community needs and we have had the opportunity to build large regional shopping malls, national chain stores, power centers, small strip centers and corner retail shops.

We also have had the great privilege of teaming with church leaders and church builders to create worship areas for people from all walks of life. With more than 5 million square feet of worship and fellowship facilities, our religious portfolio includes projects ranging from 2,000 square feet to more than 200,000 square feet.

Industry and Market Overview

Marine Segment

We provide our services to similar customers, or in some cases, the same customers, across the markets served by our business. Our marine segment customers may be in diverse end markets, including port expansion and maintenance, bridges, causeways and other marine infrastructure, the recreational waterside industry, the U.S. Department of Defense, the energy industry, coastal protection and reclamation, along with hurricane restoration and repair and environmental remediation. We believe that this broad customer base enables us to lessen the negative effects during a downturn in a specific end market and respond quickly to the needs of expanding end markets. The following includes an overview of our diverse markets in the marine construction industry:

Port Expansion and Maintenance

Expected increases in cargo volume and future demands from larger ships transiting the expanded Panama Canal will require ports, especially along the Gulf Coast and Atlantic Seaboard, to expand their dock capacity and port infrastructure to accommodate larger container ships and increased cargo volumes, as well as perform additional dredging services to deepen and maintain their channels. We provide customers in this sector turnkey services to meet all their port expansion and maintenance work.

Bridges and Causeways

According to the American Society of Civil Engineers, as of their most recent report, one in thirteen of the nation’s bridges are structurally deficient, and the average age of the nation’s bridges is 45 years old. We are able to construct or restore overwater bridges, and design, repair, or replace, fendering systems for customers.

Marine Infrastructure

The U.S. Marine Transportation System (“MTS”) consists of waterways, ports and their intermodal connections, vessels, vehicles, and system users, as well as shipyards and repair facilities crucial to maritime activity. The MTS is primarily owned and operated through an aggregation of federal, state, and local governmental authorities, as well as privately owned facilities and private companies. U.S. inland and intracoastal waterways require continuous maintenance and improvement. While waterway usage is increasing, the facilities and supporting systems are aging. In addition, channels

Table of Contents

and waterways must maintain certain depths to accommodate ship and barge traffic. Natural sedimentation in these channels and waterways require routine maintenance dredging to maintain navigability.

Our full business complement, including design, dredging, marine construction, and specialty services, such as diving, survey, and inspections, are fully utilized by our customers to meet all their marine infrastructure project needs.

Recreational Waterside Industry

An increase in the number and size of cruise ships has generated a need for substantial port infrastructure development, including planning and construction of new terminals and facilities, as well as on-going maintenance and repair services. These larger vessels require the development of new mooring structures as well as additional dredging services to accommodate deeper drafts. Our service area includes, among others, the ports of Miami, Galveston, Tampa, New Orleans, Canaveral, Juneau, Tacoma, Seattle and the Caribbean Basin, which includes numerous cruise facilities and is the most popular cruise destination in the North American market.

The Department of Defense and Homeland Security

The U.S. Navy has the responsibility for the maintenance of 40 facilities in the United States, which includes a significant amount of marine infrastructure. We believe the U.S. Navy will continue to maintain strategic facilities, including required maintenance and upgrades to its marine facility infrastructure.

The U.S. Coast Guard maintains more than 50,000 federal aids to navigation, which include buoys, lighthouses, day beacons, and radio-navigation signals. Additionally, it has oversight responsibility for approximately 20,000 highway and railroad bridges that span navigable waterways throughout the country. As part of the Department of Homeland Security, we anticipate that the U.S. Coast Guard’s needs for varied marine construction services, including those listed above, will provide opportunities for us in the future.

Energy Industry

We design, construct, repair and remove underwater pipelines, and provide marine construction, dredging, and on-going maintenance services for private refineries, terminal facilities and docks, and other critical areas near shore oil and gas infrastructure.

U.S. Coastal and Wetland Restoration and Reclamation

Increases in coastal population density and demographic trends, along with the potential effects of rising sea-levels, will lead to an increase in the number of coastal restoration and reclamation projects, and as the value of waterside assets rises from a residential and recreational standpoint, the private sector, government agencies and municipalities will increase spending on restoration and reclamation projects.

Hurricane Restoration and Repair

Hurricanes are often very destructive to the existing marine infrastructure and natural protection barriers of the prime storm areas of the Gulf Coast, the Atlantic Seaboard, and the Caribbean Basin, including bridges, ports, underwater channels and sensitive coastal areas. Typically, restoration and repair opportunities continue for several years after a major hurricane event. These events provide incremental projects to our industry that contribute to a favorable bidding environment and high-capacity utilization in our markets during such times.

Environmental Remediation

We believe there will be additional funding for the protection of natural habitats, environmental preservation, wetlands creation and remediation for high priority projects in Louisiana and other areas in the markets we serve that will protect and restore sensitive marine and coastal areas, advance ocean science and research, and ensure sustainable use of ocean resources.

Concrete Segment

We provide our services to different customers across the markets served by our business. Our customers in the concrete segment are in diverse end markets such as industrial, institutional, commercial real estate, and recreational developments.

We believe that this broad customer base enables us to lessen the negative effects during a downturn in a specific end market and respond quickly to the needs of expanding end markets. The following includes an overview of our diverse markets in the concrete industry:

Table of Contents

Industrial developments

Our industrial markets include manufacturing plants, industrial warehousing, distribution centers, wastewater treatment facilities and facilities supporting the petrochemical industry. An expected increase in distribution has generated a need for substantial industrial park developments.

Institutional developments and expansions

Our institutional markets include educational facilities, medical facilities, museums, and religious developments. Due to significant population growth in the metropolitan areas of Texas, there has been great demand for institutional development and expansion. Additionally, as population and suburban areas grow, so does the continued need for medical and educational facilities.

Structural developments

Our structural markets include mid- and high-rise multi-family living, single and multi-story office buildings, parking garages, shopping malls, and other multi-story buildings. Continued growth in business expansions and relocations to Texas are driving an increase in the need for office space and apartment complexes.

Retail developments

As population continues to grow, so does the need for retail developments, such as grocery stores, shopping malls, restaurants, free standing retail outlets, and other entertainment venues.

Recreational developments

Our recreational markets include a wide range of hotels, sports venues, and stadiums. The increase in new businesses and new educational facilities has sparked the need for additional hotels and stadiums across the metropolitan areas of Texas.

Customers

Our customers in the marine segment include federal, state and local governmental agencies as well as private commercial and industrial enterprises in the United States and the Caribbean Basin. Customers in our concrete segment include general contractors along with owners and developers of medical facilities, religious developments, sports complexes and stadiums, school districts and developers, owners of industrial, commercial and residential buildings, and some governmental agencies across the metropolitan areas of Texas. Most projects are competitively bid, with the award typically going to the lowest qualified bidder. Our customer base shifts from time to time depending on the types of projects we bid, and ultimately are successful on obtaining.

The following table represents contract revenue and concentrations of contract revenue by type of customer for the years ended December 31, 2022, 2021 and 2020.

We do not believe that the loss of any one customer would have a material adverse effect on our operations since no single customer sustains a large portion of our contract revenue over time.

Fluctuations in Quarterly Results

Our quarterly revenues and results of operations may fluctuate significantly depending upon the mix, size, scope, and progress schedules of our projects under contract, permitting, weather or other delays, the productivity of our labor force and the utilization of our equipment. These factors, as well as others, affect the rate at which revenue is recognized as projects are completed.

Competition

In our marine segment, we compete with several regional marine construction services companies and a few national marine construction services companies. In the past, interest groups have unsuccessfully lobbied Congress to modify or

Table of Contents

repeal the Jones Act to facilitate foreign flag competition for trades and cargos currently reserved for U.S. flag vessels under the Jones Act. If these efforts are ever successful, it could result in significantly increased competition and have a material adverse effect on our marine segment business, results of operations, cash flows or financial condition. From time to time, we compete with certain national land-based heavy civil contractors.Inourconcretesegment,wecompetemostlyintheprivatesectorandourcompetitorsrangefromsmall,local construction companies to large regional and national constructioncompanies.

Both of our segments are highly fragmented with competitors generally varying within the markets we serve and with few competitors competing in all of the markets we serve or for all of the services that we provide. We believe that our turnkey capability, expertise, experience and reputation for providing safe and timely quality services, safety record and programs, versatile equipment fleet, financial strength, surety bonding capacity, knowledge of local markets and conditions, and project management and estimating abilities allow us to compete effectively. We believe significant barriers to entry exist in the markets in which we operate, including the ability to bond large projects, maritime law constraints, specialized marine equipment and technical experience; however, a U.S. company that has adequate financial resources, access to technical expertise, and specialized equipment may become a competitor.

Insurance and Bonding

We maintain general and excess liability, construction equipment, workers’ compensation and other forms of insurance; all in amounts adequate for our operating needs and consistent with industry practice.

In connection with both segments of the business, we often are required to provide various types of surety bonds that provide security for our performance under certain public and private sector contracts. Our ability to obtain surety bonds depends upon our capitalization, adequate working capital, past performance, management expertise, and external factors, including the capacity of the overall surety market. Surety companies consider such factors in light of the amount of our backlog that we have currently bonded and their own current underwriting standards, which may change from time to time. The capacity of the surety market is subject to market-driven fluctuations driven primarily by the level of surety industry losses and the degree of surety market consolidation. Although we do not believe that fluctuations in surety market capacity have significantly affected our ability to grow our business, there is no assurance that it will not significantly affect our ability to obtain new contracts in the future. The bonds we provide typically are for the contract amount of the project. At December 31, 2022, the capacity under our current bonding arrangement was at least $750 million, with approximately $175 million of projects being bonded. We believe our strong balance sheet and working capital position will allow us to continue to access our bonding capacity.

Trade Names

We operate under a number of trade names. We consolidate our operations under the brand name “Orion Group Holdings,Inc.”WemaybeknownasOrionMarineGroup,OrionMarineConstruction,OrionMarineContractors,Orion Construction, East and West Jones Placement Area, Schneider E&C, Orion Industrial Construction, Orion Concrete Construction, T.A.S.

While we consider our trade names to be valuable assets, we do not consider any singletrademarkortradenametobeofsuch materialimportancethatitsabsencewouldcauseamaterialdisruptionofour business.

Equipment

We operate and maintain a large and diverse equipment fleet in our marine and concrete segments, substantially all of which we own, that includes the following:

Table of Contents

We believe that ownership of certain equipment is generally preferable to leased or rented equipment in some cases because it ensures the equipment is available as needed and normally results in lower costs. We continually monitor and adjust our fleet size so that it is consistent with the size of the business, considering both existing backlog and expected future work. We believe that our equipment is well maintained and suitable for our current operations. We have the ability to extend the useful life of our equipment through capital refurbishment at periodic intervals. Most of our fleet is serviced by our own mechanics who work at various maintenance sites and facilities. We are also capable of building, and have built, much of our highly specialized equipment. Our strategy is to deploy our fleet from project to project as required.

Equipment Certification

In our marine segment, some of our equipment requires certification by the U.S. Coast Guard. All equipment which requires certification has obtained such certification and is maintained in good standing thereunder. In addition, where required, our vessels’ permissible loading capacities require certification by the American Bureau of Shipping (“ABS”). The ABS is an independent classification society which certifies that certain of our larger, seagoing vessels are “in-class,” signifying that the vessels have been built and maintained in accordance with ABS standards and applicable U.S. Coast Guard rules and regulations. All of our vessels that are required to be certified by the ABS have been certified as “in-class.” These certifications indicate that the vessels are structurally capable of operating in open waters, which enhances the mobility of our fleet.

Government Regulations

We are required to comply with the macro regulatory requirements of federal, state and local governmental agencies and authorities including the following:

● licensing requirements applicable to shipping and dredging; and

In our marine segment, we are also subject to government regulations pursuant to the Foreign Dredge Act, the Merchant Marine Act of 1920, commonly referred to as the "Jones Act", the Shipping Act and the Vessel Documentation Act. These statutes require vessels engaged in the transport of merchandise or passengers between two points in the United States or dredging in the navigable waters of the U.S. 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 U.S. The U.S. citizenship ownership and control standards require the vessel-owning entity to be at least 75% U.S. citizen owned and prohibit the demise or bareboat

Table of Contents

chartering of the vessel to any entity that does not meet the 75% U.S. citizen ownership test. These statutes, together with similar requirements for other sectors of the maritime industry, are collectively referred to as “cabotage” laws.

In both our marine and concrete segments, we are subject to the requirements of OSHA and certain regulations for the EPA.

We believe that we are in material compliance with applicable regulatory requirements and have all material licenses required to conduct our operations.

Environmental Matters

General

Our activities, including concrete construction, infrastructure construction, salvage, demolition, dredging and dredge material disposal activities are subject to stringent and complex federal, state, and local laws and regulations governing environmental protection, including air emissions, water quality, solid waste management, marine and bird species and their habitats, and wetlands. A portion of our construction contracts are entered into with public authorities and frequently impose additional governmental requirements, including those related to environmental concerns.

Such laws and regulations may require that both segments and their customers obtain, and comply with, various environmental permits, registrations, licenses and other approvals. These laws and regulations also can restrict or impact the business activities in many ways, such as delaying the appropriation and performance of particular projects; restricting the way we handle or dispose of wastes; requiring remedial action to mitigate pollution conditions that may be caused by our operations or that are attributable to others; and enjoining some or all of our operations deemed in non-compliance with environmental laws and regulations. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and/or criminal penalties, the imposition of remedial obligations and the issuance of orders enjoining future operations.

We believe that compliance with existing federal, state and local environmental laws and regulations will not have a material adverse effect on our business, results of operations, or financial condition. In addition, we could be affected by future laws or regulations. As a result, there can be no assurance as to the amount or timing of future expenditures for environmental compliance or remediation, and actual future expenditures may be different from the amounts we currently anticipate. The following is a discussion of the environmental laws and regulations that could have a material effect on our marine and concrete construction services.

Waste Management

Our operations could be subject to the federal Resource Conservation and Recovery Act (“RCRA”) and comparable state laws, which impose detailed requirements for the handling, storage, treatment and disposal of hazardous and non-hazardous solid wastes. Under the auspices of the EPA, the individual states administer some or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent, requirements. Generators of hazardous wastes must comply with certain standards for the accumulation and storage of hazardous wastes, as well as recordkeeping and reporting requirements applicable to hazardous waste storage and disposal activities.

Site Remediation

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as “Superfund,” and comparable state laws and regulations impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons responsible for the release of hazardous substances into the environment. Such classes of persons include the current and past owners or operators of sites where a hazardous substance was released, and companies that disposed or arranged for the disposal of hazardous substances at offsite locations, such as landfills. CERCLA authorizes the EPA, and in some cases third parties, to take actions in response to threats to the public health or the environment and to seek to recover from the responsible classes of persons the costs they incur. Under CERCLA, such persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. In addition, neighboring landowners and other third parties often file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment.

Table of Contents

We currently own or lease properties that have been used by other industries for a number of years. Although we typically have used operating and disposal practices that were standard in the industry at the time, wastes may have been disposed of or released on or under the properties owned or leased by us, on or under other locations where such substances have been taken for disposal, or on or under project sites where we perform work. In addition, some of the properties may have been operated by third parties or by previous owners whose treatment and disposal or release of wastes was not under our control. These properties and the substances disposed or released on them may be subject to CERCLA, RCRA and analogous state laws. Under such laws, we could be required to remove or remediate previously disposed wastes or property contamination, or to perform remedial activities to prevent future contamination.

Water Discharges

The Federal Water Pollution Control Act, also known as the Clean Water Act (“CWA”), and analogous state laws impose strict controls with respect to the discharge of pollutants, including spills and leaks of oil and other substances, into waters of the United States, including wetlands. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. The CWA also regulates the discharge of dredged or fill material into waters of the U.S., and activities that result in such discharge generally require permits issued by the Corps of Engineers. Moreover, above ground storage of petroleum products is strictly regulated under the CWA. Under the CWA, federal and state regulatory agencies may impose administrative, civil and/or criminal penalties for non-compliance with discharge permits or other requirements of the CWA and analogous state laws and regulations.

The Oil Pollution Act of 1990 (“OPA”), which amends and augments the CWA, establishes strict liability for owners and operators of facilities that are sites of releases of oil into waters of the U.S. OPA and its associated regulations impose a variety of requirements on responsible parties related to the prevention of oil spills and liability for damages resulting from such spills. For instance, OPA requires vessel owners and operators to establish and maintain evidence of financial responsibility sufficient to cover liabilities related to an oil spill for which such parties are statutorily responsible. We believe we are in compliance with all applicable OPA financial responsibility obligations and equipment requirements.

In 2009, regulations promulgated by the EPA covering certain previously exempt discharges to water from certain marine vessels became effective. The regulations provide for a general permit to cover such discharges and impose on marine vessel operators, including us, certain discharge, permitting, record keeping, reporting, monitoring, maintenance, and operating restrictions and requirements with respect to materials that are or may be discharged from certain vessels. The applicability of these restrictions and requirements is based on size and type of vessel, and they apply only to a minority of our vessels. We, nevertheless, are implementing such restrictions and requirements with respect to our vessels which are subject thereto, and we do not anticipate that such regulations or the associated permit terms, restrictions and requirements will adversely impact our business and results of operations.

Air Emissions

The Clean Air Act (“CAA”) and comparable state laws restrict the emission of air pollutants from many sources, including paint booths, and may require pre-approval for the construction or modification of certain facilities expected to produce air emissions, impose stringent air permit requirements, or require the utilization of specific equipment or technologies to control emissions. We believe that our operations are in substantial compliance with the CAA.

Endangered Species

The Endangered Species Act (“ESA”) restricts activities that may affect endangered species or their habitats. We conduct activities in or near areas that may be designated as habitat for endangered or threatened species. For instance, seasonal observation of endangered or threatened West Indian Manatees adjacent to work areas may impact construction operations in Florida during the winter months. Additionally, our dredging operations in Florida are impacted by limitations for placement of dredge spoil materials on designated spoil disposal islands, from April through August of each year, when the islands are inhabited by nesting colonies of protected bird species. Further, restrictions on work during the Whooping Crane nesting period in the Aransas Pass National Wildlife Refuge from October 1 through April 15 each year and during the non-dormant grass season for sea grass in the Laguna Madre from March 1 through November 30 each year impact our construction operations in the Texas Gulf Coast area. We plan our operations and bidding activity with these restrictions and limitations in mind, and they have not materially hindered our business in the past. However, these and other restrictions may affect our ability to obtain work or to complete our projects on time in the future. In addition, while

Table of Contents

we believe that we are in material compliance with the ESA, the discovery of previously unidentified endangered species could cause us to incur additional costs or become subject to operating restrictions or bans in the affected area.

Climate Change

The U.S. Congress may consider legislation to reduce emissions of greenhouse gases in response to climate change concerns. In addition, several states have declined to wait on Congress to develop and implement climate control legislation and have already taken legal measures to reduce emissions of greenhouse gases. Passage of climate control legislation or other regulatory initiatives by Congress or various states, or the adoption of regulations by the EPA and analogous state agencies that restrict emissions of greenhouse gases in areas in which we conduct business could have an adverse effect on our operations and demand for our services.

Human Capital Management

As of December 31, 2022, our marine segment had 868 employees, 286 of whom were full-time salaried personnel and most of the remainder of whom were hourly personnel. Our concrete segment had 1,348 employees, 197 of whom were full-time salaried personnel and most of the remainder were hourly personnel.

From time to time, we hire additional employees for certain large projects and, subject to local market conditions, additional crew members are generally available for hire on relatively short notice. We believe our employees are our most valuable resource, and our workforce possesses a strong dedication to and pride in our company. Our employees are not currently represented by labor unions, except certain employees in our marine segment located in the Pacific Northwest and Alaska and certain employees operating specialized equipment for our concrete segment, in respect of which collective bargaining agreements are in place. Employees represented by collective bargaining agreements represent approximately 4.3% of our total workforce.

Financial Information About Geographic Areas

We are a project-driven marine and concrete contractor, and our operations represent two reportable segments for financial reporting. Our business is primarily conducted along the coastal regions of the United States for our marine segment and in the metropolitan areas of Texas for our concrete segment. Revenues generated from our marine segment outside the United States, primarily in the Caribbean Basin and Mexico, totaled 0.9%, 0.5%, and 1.8% of total revenues for the years ended December 31, 2022, 2021 and 2020, respectively. Our long-lived assets are substantially located in the United States.

Item 1A. RISK FACTORS

We operate in a changing environment that involves numerous known and unknown risks and uncertainties that could materially adversely affect our business, financial condition, and results of operations. The risks described below highlight some of the factors that have affected and could affect us in the future. We may also be affected by unknown risks or risks that we currently think are immaterial. If any such events actually occur, our business, financial condition, and results of operations could be materially adversely affected.

Risk Factors Relating to Our Business

We rely on highly competitive and highly regulated government contracts.

Government funding for public works projects is limited, thus creating a highly competitive environment for the limited number of public projects available. Reduced levels of, or delays in, government funding cause delays in project lettings and result in intense competition and pricing pressure for such projects. In addition, government contracts are subject to specific procurement regulations, contract provisions and a variety of regulatory requirements relating to their formation, administration, performance and accounting. Many of these contracts include express or implied certifications of compliance with applicable laws and contract provisions. Any violations of these regulations could bring about litigation,

Table of Contents

including the possibility of qui tam (“whistleblower”) litigation brought by private individuals on behalf of the government under the Federal Civil False Claims Act, and could cause termination of other existing government contracts and result in the loss of future government contracts. Due to the significant competition in the marketplace and the level of regulations on government contracts, we could suffer reductions in new projects and see lower revenues and profit margins on those projects, which could have a material adverse effect on the business, operating results and financial condition.

Our operations are susceptible to a variety of adverse conditions including weather conditions, natural disasters, health epidemics or pandemics or other contagious outbreaks and terrorist attacks that could negatively impact the markets in which we operate.

Our business, operating results and financial condition could be materially and adversely affected by severe weather and other natural disasters, such as earthquakes or hurricanes, particularly along the Gulf Coast, the West Coast, the Atlantic Seaboard, and the Caribbean Basin. Repercussions of severe weather conditions could cause significant interruption of projects in process and have safety implications to personnel at those sites.

Our business, operating results and financial condition could be materially and adversely affected if a public health epidemic or pandemic or other contagious outbreak, such as the recent coronavirus (“COVID-19”) pandemic (as discussed in greater detail below), interferes with our ability, or that of our employees, contractors, suppliers, customers and other business partners to perform our and their respective responsibilities and obligations relative to the conduct of our business.

Terrorist attacks, targeted at ports, marine facilities, shipping or metropolitan areas could affect the markets in which we operate our business and our expectations. Increased armed hostilities, terrorist attacks or responses from the United States may lead to further acts of terrorism and civil disturbances in the United States or elsewhere, which may further contribute to economic instability in the United States. These attacks or armed conflicts may affect our operations or those of our customers or suppliers and could impact our revenues, our production capability and our ability to complete contracts in a timely manner.

Demand for our services may decrease due to economic recession or a reduction of demand in end markets of our customers.

Our concrete segment depends on continued growth in population in our geographic market areas in Texas to support residential and nonresidential construction. A growing population generates economic growth and expansion in construction for retail, office buildings, etc. If the population decreases or slows in growth, it may adversely affect economic growth and ultimately limit the need for residential and nonresidential construction services in the areas we currently perform services.

Moreover, even when the underlying economic fundamentals that ordinarily drive the level of construction activity are strong, the level of economic activity in such markets may be suppressed during inflationary periods that are accompanied by increasing interest rates. There is a risk that, if the Federal Reserve Board continues to increase interest rates to respond to inflation concerns, our concrete business could see a reduction in demand.

The timing of new contracts may result in volatility in our cash flow and profitability. These factors as well as others that may cause our actual financial results to vary from any publicly disclosed earnings guidance and forecasts are outside of our control.

Our revenues are generated from project-based work. It is generally very difficult to predict the timing and source of awarded contracts. The selection of, timing of, or failure to obtain projects, delays in awards of projects, the rebidding or termination of projects due to budget overruns, or the cancellations of projects or delays in completion of contracts could result in the under-utilization of our assets and reduce our cash flows and profitability. Even if we are awarded contracts, we face additional risks that could affect whether, or when, work will begin. For example, some of our contracts are subject to financing and other contingencies that may delay or result in termination of projects. This may make it difficult to match workforce size and equipment location with contract needs. In some cases, we may be required to bear the cost of a readily available workforce and fleet of equipment that is larger than needed at the time, resulting in unpredictability in our cash flow, expenses and profitability. If an expected contract award or the related notice to proceed is delayed or not received, we could incur substantial costs without receipt of any corresponding revenues. Delays by our customers in obtaining

Table of Contents

required approvals and permits for their infrastructure projects may delay their awarding contracts for those projects and, once awarded, the ability to commence construction under those contracts. Moreover, construction projects for which our services are contracted may require significant expenditures by us prior to receipt of relevant payments by a customer and may expose us to potential credit risk if such customer should encounter financial difficulties. Such expenditures could reduce our cash flows and necessitate increased borrowings under our credit facility. Finally, the winding down or completion of work on significant projects that were active in previous periods will reduce our revenue and earnings if such significant projects have not been replaced in the current period. From time to time we may publicly provide earnings or other forms of guidance, which reflect our predictions about future revenue, operating costs and capital structure, among other factors. Any such predictions may be impacted by these factors as well as others that are beyond our control and might not turn out to be accurate.

Fluctuations in commodity prices or interest rates may affect our customers’ investment decisions and therefore subject us to risks of cancellation, delays in existing work, or changes in the timing and funding of new awards. Additionally, fluctuations in commodity prices can negatively affect our project costs.

Commodity prices can affect our customers in a number of ways. For example, for those customers that produce commodity products such as oil, gas, concrete, steel products, fluctuations in price can have a direct effect on their profitability and cash flow and, therefore, their willingness to continue to invest or make new capital investments. To the extent commodity prices decline or fluctuate and our customers defer new investments or cancel or delay existing projects, the demand for our services decreases, which may have a material adverse impact on the business, financial condition, and results of operations.

Additionally, rising interest rates may affect the cost of financing for our customers’ capital projects and investments. These increased costs may affect their capacity and willingness to undertake new investments, and may result in the delay or cancellation of projects they would otherwise undertake.

Commodity prices can also strongly affect the costs of projects. We use concrete and steel as well as diesel fuel and other petroleum-based products to operate our equipment used in our construction contracts. Fluctuations in supplies relative to demand and other factors can cause unanticipated increases in their cost. Rising commodity prices can negatively impact the potential returns on projects that are planned, as well as those in progress, and result in customers deferring new investments or canceling or delaying existing projects. The short-term nature of the majority of our projects typically protects us from these potential price increases, however, if we are unable to procure commodities for completion of our projects at estimated prices due to rising commodity prices, our margins may erode on certain in progress or future projects.

We may be unable to obtain sufficient bonding capacity for our contracts and the need for performance and surety bonds may adversely affect our business.

As more fully described in “Insurance and Bonding” under “Item 1. Business,” we are generally required to post bonds in connection with government and certain private sector contracts to ensure job completion. We have entered into a bonding agreement with a large multinational surety which acts as surety, issues bid bonds, performance bonds and payment bonds, and obligates itself upon other contracts of guaranty required by us in the day-to-day operations of our business. However, our surety is not obligated under the bonding agreement to issue bonds for us and bonding decisions are made on a case-by-case basis. We may not be able to maintain a sufficient level of bonding capacity in the future, which could preclude us from being able to bid for certain contracts and successfully contract with certain customers, or cause us to have to increase our letter of credit utilization in lieu of bonds, thereby reducing available borrowing capacity under our credit facility. In addition, the conditions of the bonding market may change, increasing our costs of bonding or restricting our ability to get new bonding which could have a material adverse effect on our business, operating results and financial condition.

Our business depends on good customer relationships and our reputation in both the marine and concrete infrastructure markets, which is developed and maintained by our executives and key project managers. Loss of any of our relationships, reputation or executives or key project managers could materially reduce our revenues and profits.

Our contracts are typically entered into on a project-by-project basis, so we generally do not have continuing contractual commitments with our customers beyond the terms of the current contract. We benefit from key customer relationships

Table of Contents

built over time and with both public and private entities. We also benefit from our reputation in the marine and concrete construction markets developed over years of successfully performing on projects. Both of these aspects of our business were developed and are maintained through our executives and key project managers. Our inability to retain our executives and key project managers or inability to complete projects timely and successfully resulting in customer satisfaction could have a material adverse effect on our current customer relationships and reputation. The inability to maintain relationships with our customers in general or obtain new customers based on our reputation could have a material adverse effect on our business, operating results and financial condition.

We may not be able to fully realize the revenue value reported in our backlog.

As of December 31, 2022, we had a backlog of work to be completed on contracts totaling approximately $216.7 million in our marine segment and approximately $232.1 million in our concrete segment. Backlog develops as a result of new awards, which represent the potential revenue value realizable pursuant to new project commitments received by us during a given period.

Backlog consists of awarded projects which have either (a) not yet been started or (b) are in progress but are not yet complete. In the latter case, the revenue value reported in backlog is the remaining value related to work that has not yet been completed. We cannot guarantee that the revenue projected in our backlog will be realized, or if realized, will result in earnings. From time-to-time, projects are cancelled that appeared to have a high certainty of going forward at the time they were recorded as new awards. In the event of a project cancellation, we may be reimbursed for certain costs but typically have no contractual right to recover the total revenue reflected in our backlog. In addition to being unable to recover certain direct costs, cancelled projects may also result in additional unrecoverable costs due to the resulting under-utilization of our assets or labor force.

We could suffer contract losses if we fail to accurately estimate our costs or fail to execute within our cost estimates on fixed-price, lump-sum contracts.

Much of our revenue is derived from fixed-price, lump-sum contracts. Under these contracts, we perform our services and execute our projects at a fixed price and where, as a result, we could benefit from cost savings, but we may be unable to recover any cost overruns. Fixed-price contracts carry inherent risks, including risks of losses from underestimating costs, operational difficulties and other factors that may occur over the contract period. If our cost estimates for a contract are inaccurate, or if we do not execute the contract within our cost estimates, we may incur losses or the project may not be as profitable as we expected. In addition, we are sometimes required to incur costs in connection with modifications to a contract (change orders) that may not be approved by the customer as to scope and/or price, or to incur unanticipated costs, including costs for customer-caused delays, errors in specifications or designs, or contract suspension or termination that we may not be able to recover. These, in turn, could have a material adverse effect on our business, operating results and financial condition. The revenue, cost and gross profit realized on such contracts can vary, sometimes substantially, from the original projections due to changes in a variety of factors, such as:

● project modifications creating unanticipated costs;

● differing site conditions;

● changes in the costs of equipment, materials, labor or subcontractors;

● our suppliers’ or subcontractors’ failure to perform;

● changes in local laws and regulations;

● changes in ad valorem and other tariffs;

● delays caused by local weather conditions; and

Table of Contents

These risks may increase if the project is of a long-term duration because of the elevated risk that the circumstances upon which we based our original bid will change in a manner that increases costs. In addition, we sometimes bear the risk of delays caused by unexpected conditions or events.

We could suffer penalties on our contracts for late completion.

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, without sufficient justification, 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.

Our projects could be hindered due to our dependence on third parties to complete many of our contracts.

A portion of the work performed under our contracts is performed by third-party subcontractors we hire. We also rely on third-party equipment manufacturers or suppliers to provide much of the materials used for projects. If we are unable to hire qualified subcontractors or find qualified equipment manufacturers or suppliers, our ability to successfully complete a project could be impaired. If we are not able to locate qualified third-party subcontractors or the amount we are required to pay for subcontractors or equipment and supplies exceeds what we have estimated, especially in a lump-sum or a fixed-price contract, we may suffer losses on these contracts. If a subcontractor, supplier, or manufacturer fails to provide services, supplies or equipment as required under a contract for any reason, we may be required to source these services, equipment or supplies to other third parties on a delayed basis or on less favorable terms, which could impact contract profitability. There is a risk that we may have disputes with our subcontractors relating to, among other things, the quality and timeliness of work performed, customer concerns about the subcontractor, or our failure to extend existing task orders or issue new task orders under a contract. In addition, faulty workmanship, equipment or materials could impact the overall project, resulting in claims against us for failure to meet required project specifications.

In the current economic environment, third parties may find it difficult to obtain sufficient financing to help fund their operations. The inability to obtain financing could adversely affect a third party’s ability to provide materials, equipment or services which could have a material adverse impact on our business, financial condition, and results of operations. In addition, a failure by a third party subcontractor, supplier or manufacturer to comply with applicable laws, regulations or client requirements could negatively impact our business and, for government clients, could result in fines, penalties, suspension or even debarment being imposed on us, which could have a material adverse impact on our business, financial condition, and results of operations.

We may incur higher costs to acquire, manufacture and maintain equipment necessary for our operations.

We have traditionally owned the majority of the equipment used in our projects, and we do not bid on contracts for which we do not have, or cannot quickly procure, whether through construction, acquisition or lease, the necessary equipment to complete projects. We are capable of building much of the specialized equipment used in our projects, including dayboats, tenders and dredges. To the extent that we are unable to buy or build equipment necessary for our needs, either due to a lack of available funding or equipment shortages in the marketplace, we may be forced to rent equipment on a short-term basis, which could increase the costs of completing contracts, thereby reducing contract profitability. In addition, our equipment requires continuous maintenance, which we primarily provide through our own repair facilities, as well as certification by the U.S. Coast Guard for certain marine segment assets. If we are unable to continue to maintain the equipment in our fleet or are unable to obtain the requisite certifications, we may be forced to obtain third-party repair services, be unable to use our uncertified equipment or be unable to bid on contracts, which could have a material adverse effect on our business, operating results and financial condition.

In addition, our vessels in the marine segment may be subject to arrest or seizure by claimants as security for maritime torts committed by the vessel or us or the failure by us to pay for necessities, including fuel and repair services, which were furnished to the vessel. Such arrest or seizure could preclude the vessel from working, thereby causing delays in marine segment projects.

Table of Contents

Our business is subject to significant operating risks and hazards that could result in damage or destruction to property, injuries or loss of life, which could result in losses or liabilities to us.

Construction and maintenance sites are potentially dangerous workplaces and often put our employees and others in close proximity with mechanized equipment, moving vehicles, or other construction or worksite hazards. On most sites, we are responsible for safety and are contractually obligated to implement safety procedures. Our safety record is an important consideration for us and for our customers. If serious accidents or fatalities occur or our safety record was to deteriorate, we may be excluded from bidding on certain work, expose ourselves to possible lawsuits, and existing service arrangements could be terminated, thus having a material adverse impact on our financial position, results of operations, cash flows and liquidity. Further, regulatory changes implemented by OSHA or the U.S. Coast Guard could impose additional costs on us. 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.

The businesses of marine infrastructure construction, port maintenance, dredging and salvage are generally subject to a number of risks and hazards, including environmental hazards, industrial accidents, hurricanes, adverse weather conditions, collisions with fixed objects, cave-ins, encountering unusual or unexpected geological formations, disruption of transportation services and flooding. These risks could result in damage to or destruction of, dredges, transportation vessels, other maritime structures and buildings, and could also result in personal injury or death, environmental damage, performance delays, monetary losses or legal liability.

In the concrete segment, our workers are subject to the usual hazards associated with providing construction and related services on construction sites including environmental hazards, industrial accidents, hurricanes, adverse weather conditions, and flooding. Operating hazards can cause personal injury or death, damage to or destruction of property, plant and equipment, environmental damage, performance delays, monetary losses or legal liability.

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 general liability and workers’ compensation. We are partially self-insured under some of our policies, and our insurance does not cover all types or amounts of liabilities. We are not required to, and do not, specifically set aside funds for our self-insurance programs.

At any given time, we are subject to multiple workers’ compensation and personal injury claims. We maintain substantial loss accruals for workers’ compensation claims, and, until recently, our workers’ compensation and insurance costs have been rising for several years notwithstanding our emphasis on safety. Our insurance policies may not be adequate to protect us from liabilities that we incur in our business. In addition, some of the projects that we bid on require us to maintain high levels of builder’s risk insurance. 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, operating results and financial condition.

Furthermore, due to a variety of factors such as increases in claims and projected significant increases in medical costs, our insurance premiums may increase in the future and we may not be able to obtain similar levels of insurance on reasonable terms, or at all. Any such inadequacy of, or inability to obtain, insurance coverage at acceptable rates, or at all, could have a material adverse effect on our business, operating results and financial condition.

Insurance liabilities are difficult to assess and quantify due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents not reported and the effectiveness of our safety program. If we were to experience insurance claims or costs above our estimates, we might be required to use working capital to satisfy these costs rather than to maintain or expand our operations. To the extent that we experience a material increase in the frequency or severity of accidents or workers’ compensation and health claims, or unfavorable developments on existing claims, our operating results and financial condition could be materially and adversely affected.

Our operations are subject to environmental laws and regulations that may expose us to significant costs and liabilities.

Our marine infrastructure construction, salvage, demolition, dredging and dredge material disposal activities are subject to stringent and complex federal, state and local environmental laws and regulations, including those concerning air

Table of Contents

emissions, water quality, solid waste management, and protection of certain marine and bird species, their habitats, and wetlands. We may incur substantial costs in order to conduct our operations in compliance with these laws and regulations. For instance, we may be required to obtain, maintain and comply with permits and other approvals (as well as those obtained for projects by our customers) issued by various federal, state and local governmental authorities; limit or prevent releases of materials from our operations in accordance with these permits and approvals; and install pollution control equipment. In addition, compliance with environmental laws and regulations can delay or prevent our performance of a particular project and increase related project costs. Moreover, new, stricter environmental laws, regulations or enforcement policies, including those imposed in response to climate change, could be implemented that significantly increase our compliance costs, or require us to adopt more costly methods of operation.

Failure to comply with environmental laws and regulations, or the permits issued under them, may result in the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations and the issuance of injunctions limiting or preventing some or all of our operations. In addition, strict joint and several liability may be imposed under certain environmental laws, which could cause us to become liable for the investigation or remediation of environmental contamination that resulted from the conduct of others or from our own actions that were in compliance with all applicable laws at the time those actions were taken. Further, it is possible that we may be exposed to liability due to releases of pollutants, or other environmental impacts that may arise in the course of our operations. For instance, some of the work we perform is in underground and water environments, and if the field location maps or waterway charts supplied to us are not accurate, or if objects are present in the soil or water that are not indicated on the field location maps or waterway charts, our underground and underwater work could strike objects in the soil or the waterway bottom containing pollutants and result in a rupture and discharge of pollutants. In addition, we sometimes perform directional drilling operations below certain environmentally sensitive terrains and water bodies, and due to the inconsistent nature of the terrain and water bodies, it is possible that such directional drilling may cause a surface fracture releasing subsurface materials. These releases may contain contaminants in excess of amounts permitted by law, may expose us to remediation costs and fines and legal actions by private parties seeking damages for non-compliance with environmental laws and regulations or for personal injury or property damage. We may not be able to recover some or any of these costs through insurance or increased revenues, which may have a material adverse effect on our business, operating results and financial condition. See “Business - Environmental Matters” for more information.

Our concrete segment is subject to extensive and complex regulations that affect land development and building construction, including zoning, density restrictions, building design and building standards. These regulations often provide broad discretion to the administering governmental authorities as to the conditions we must meet prior to development or construction being approved, if approved at all. We are subject to determinations by these authorities as to the adequacy of water or sewage facilities. New building developments may also be subject to various assessments for schools and other public improvements. In addition, in many markets government authorities have implemented no growth or growth control initiatives. Any of these can limit, delay or increase the costs of development and construction.

The anticipated investment in port and marine infrastructure may not be as large as expected, which may result in periods of low demand for our marine construction services.

The demand for port construction, maintenance infrastructure services and dredging may be vulnerable to downturns in the economy generally and in the marine transportation industry specifically. The amount of capital expenditures on port facilities and marine infrastructure in our markets is affected by the actual and anticipated shipping and vessel needs of the economy in general and in our geographic markets in particular. If the general level of economic activity deteriorates, our customers may delay or cancel expansions, upgrades, maintenance and repairs to their infrastructure. A number of other factors, including the financial condition of the shipping industry, could adversely affect our customers and their ability or willingness to fund capital expenditures in the future. During downturns in the U.S. or world economies, the anticipated port usage in our geographic markets may decline, resulting in less port construction, upgrading and maintenance. As a result, demand for our services could substantially decline for extended periods.

Table of Contents

Restrictions on foreign ownership of our vessels could limit our ability to sell off any portion of our marine construction segment or result in the forfeiture of our vessels or in our inability to continue our operations in United States navigable waters.

The Foreign Dredge Act of 1906, the Merchant Marine Act of 1920 (the “Jones Act”), the Shipping Act of 1984 and the Vessel Documentation Act require vessels engaged in thetransportofmerchandiseorpassengersbetweentwopointsintheUnitedStatesordredginginthenavigablewatersof the United States to be owned and controlled by United States citizens. The United States citizen ownership and control standards require the vessel-owning entity to be at least 75% U.S. citizen-owned, thus restricting foreign ownership interests in the entities that directly or indirectly own the vessels which we operate. If we were to seek to sell any portion of our marine segment that owns any of these vessels, we may have fewer potential purchasers, since some potential purchasers might be unable or unwilling to satisfy the foreign ownership restrictions described above; additionally, any sales of certain of our larger vessels to foreign buyers would be subject to approval by the U.S. Maritime Administration. As a result, the sales price for that portion of our marine segment may not attain the amount that could be obtained in an unregulatedmarket.

The COVID-19 pandemic affected and may again adversely affect our business and results of operations and financial condition.

The COVID-19 pandemic and related governmental and business responses had and may again have an adverse effect on the markets we derive project opportunities from, our customers, and our operations. The extent to which the COVID-19 pandemic could again impact us will depend on numerous evolving factors and future developments that are uncertain and that we are not able to predict, including: the timing, extent, trajectory and duration of the pandemic; the emergence of new variants; the development, availability, distribution and effectiveness of vaccines and treatments; the imposition of protective public safety measures; and the impact of the pandemic on the global economy and demand for our products and services. Although the COVID-19 pandemic has subsided, we could again experience adverse impacts to our business as a result of any related economic recession that occurred or may occur in the future from COVID-19 or other similar global pandemics.

Risk Factors Relating to Our Employees

We may be subject to unionization, work stoppages, slowdowns or increased labor costs.

Only a small percentage of our marine segment workforce, located in the Pacific Northwest and Alaska, is currently unionized. If at any time, a majority of our employees unionized, it could limit the flexibility of the workforce and could result in demands that might increase our operating expenses and adversely affect our profitability. Each of our different employee groups could unionize at any time and would require separate collective bargaining agreements. If any group of our employees were to unionize and we were unable to agree on the terms of their collective bargaining agreement or we were to experience widespread employee dissatisfaction, we could be subject to work slowdowns or stoppages. In addition, we may be subject to disruptions by organized labor groups protesting our non-union status. Any of these events would be disruptive to our operations and could have a material adverse effect on the business, operating results and financial condition.

Our employees in the marine segment are covered by federal laws that provide seagoing employees remedies for job-related claims in addition to those provided by state laws.

Many of our marine segment employees are covered by federal maritime law, including provisions of the Jones Act, the Longshore and Harbor Workers Act, (“USL&H”) and the Seaman’s Wage Act. Jones Act laws typically operate to make liability limits established by USL&H and state workers’ compensation laws inapplicable to these employees and to permit these employees and their representatives to pursue litigation against employers for job-related injuries. Because in some cases we are not protected by the limits imposed by state workers’ compensation statutes, we have greater exposure for claims made by these employees as compared to employers whose employees are not covered by these provisions.

For example, in the normal course of business, we are a defendant in various personal injury lawsuits. We maintain insurance to cover claims that arise from injuries to our workforce subject to a deductible. During 2022, we recorded $0.3 million of expense for our self-insured portion of these liabilities. We believe our recorded self-insurance reserves

Table of Contents

represent our best estimate of the outcomes of these claims. Should negative trends persist; we could continue to be negatively impacted in the future.

General Risk Factors

Systems and information technology interruption or failure and data security breaches could adversely impact our ability to operate or expose us to significant financial losses and reputational harm.

We rely heavily on computer, information, and communications technology and related systems in order to properly operate our business. From time to time, we experience occasional system interruptions and delays. In the event we are unable to regularly deploy software and hardware, effectively upgrade our systems and network infrastructure, and take other steps to maintain or improve the efficiency and efficacy of our systems, the operation of such systems could be interrupted or result in the loss, corruption, or release of data. In addition, our computer and communication systems and operations could be damaged or interrupted by natural disasters, telecommunications failures, power loss, acts of war or terrorism, computer viruses, malicious code, physical or electronic security breaches, intentional or inadvertent user misuse or error, or similar events or disruptions. Any of these or other events could cause interruptions, delays, loss of critical and/or sensitive data or similar effects, which could have a material adverse impact on our business, financial condition, protection of intellectual property, and results of operations, as well as those of our clients.

In addition, we face the threat to our computer systems of unauthorized access, computer hackers, computer viruses, malicious code, organized cyber-attacks and other security problems and system disruptions, including possible unauthorized access to and disclosure of our and our clients’ proprietary or classified information. We rely on industry accepted security measures and technology to securely maintain all confidential and proprietary information on our computer systems, but they may still be vulnerable to these threats. As a result, we may be required to expend significant resources to protect against the threat of these system disruptions and security breaches or to alleviate problems caused by these disruptions and breaches. Any of these events could damage our reputation and have a material adverse effect on our business, financial condition, results of operations and cash flows.

Risk Factors Relating to Our Indebtedness and Financing Plans

Our indebtedness includes covenants and obligations with regard to our business activities that may restrict our ability to take certain actions which may negatively affect our financial condition.

At December 31, 2022, our total indebtedness under the Credit Agreement was approximately $35.0 million. We must comply with various affirmative and negative covenants contained in our Credit Agreement, some of which may restrict the way in which we would like to conduct our business. Among other things, our requirements under out debt instruments could potentially limit our ability to:

● incur additional indebtedness or liens;

● sell assets;

● make loans or investments;

● make guarantees;

● enter into any hedging agreement for speculative purposes;

● acquire or be acquired by other companies; or

● amend some of our contracts.

The restrictions under our indebtedness may prevent us from engaging in certain transactions which might otherwise be considered beneficial to us, for example, they could:

Table of Contents

We may incur additional indebtedness in the future by issuing debt instruments, under new credit agreements, under joint venture credit agreements, under capital leases or synthetic leases, on a project-finance or other basis or a combination of these. If we incur additional indebtedness in the future, it likely would be under arrangements that may have terms and conditions at least as restrictive as those contained in our existing Credit Agreement. At December 31, 2022, available capacity to borrow on the revolving lines of credit was $6.0 million. Failure to comply with the terms and conditions of any existing or future indebtedness, including current or prospective covenants, would constitute an event of default. If an event of default occurs, the lenders will have the right to accelerate the maturity of such indebtedness and foreclose upon the collateral, if any, securing that indebtedness.

Our current Credit Agreement expires on July 31, 2023. The Company’s ability to continue as a going concern is dependent upon obtaining sufficient liquidity to repay its existing credit facility through a combination of proceeds from new debt, proceeds from the sale of underutilized assets, and operating cash flow. As the Company’s refinancing activities are ongoing, there can be no assurances that the Company will be able to secure financing on terms that are acceptable to the Company or at all. An explanatory paragraph is included in the report of our independent registered public accounting firm contained in this Annual Report describing an uncertainty about our ability to continue as a going concern. The inclusion of this explanatory paragraph related to going concern is considered an event of noncompliance with the Credit Agreement. We have received a consent for this noncompliance with the Credit Agreement from our lenders.

We are negotiating with new financing sources to refinance the indebtedness under our Credit Agreement, which is due on July 31, 2023, but we cannot assure we will complete the refinancing before the maturity date or the expiration date of the lenders’ consent.

Our current Credit Agreement expires on July 31, 2023, and all amounts there under are due on such date. The consent from our lenders expires on May 1, 2023. The Company does not presently have sufficient cash or other sources of liquidity to repay the debt under Credit Agreement at maturity or the expiration date of the consent. We are presently negotiating with financing sources to refinance the indebtedness under the Credit Agreement, but there is no assurance we will complete the financing before the maturity date, the expiration of the consent or at all. Our negotiation with financing sources is a rapidly evolving situation.

Failure to secure a new credit facility before the maturity date of the Credit Agreement or expiration of the consent from the lenders could restrict our access to capital which could prevent us from repaying amounts borrowed under our existing credit facility, from funding our operations, or from engaging in certain transactions which might otherwise be considered beneficial to us. In this event, we may be required to delay, limit, reduce, or terminate certain commercial efforts or strategies, may need to accelerate or add to planned disposals of certain equipment, real estate, or other assets, and may be prevented, or hindered from pursuing or performing contracts, all of which could adversely affect our business and stockholders.

As described in Note 11 of the Notes to the Consolidated Financial Statements beginning on page F-1 of this Annual Report on Form 10-K, we had $35.0 million of outstanding indebtedness under our Credit Facility as of December 31, 2022. Because that Credit Agreement matures on July 31, 2023, and we have not yet completed the work necessary to refinance the outstanding indebtedness under the Credit Agreement, our independent registered public accounting firm included in its report covering our audited financial statements for the period ended December 31, 2022, an explanatory paragraph describing the uncertainty about our ability to continue as a going concern. Please see the Notes to the Consolidated Financial Statements beginning on page F-10 of this Annual Report on Form 10-K.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under the Credit Facility allow for loans at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed will remain the same, and our net income and operating cash flows, including cash available for servicing our indebtedness, will correspondingly decrease.

Table of Contents

Additionally, rising interest rates may increase our cost of capital and, therefore, reduce the amount of capital available to fund our operations.

Our bonding requirements may limit our ability to incur indebtedness.

We generally are required to provide various types of surety bonds that provide an additional measure of security for our performance under certain government and private sector contracts. Our ability to obtain surety bonds depends upon various factors including our capitalization, working capital and amount of our indebtedness. In order to help ensure that we can obtain required bonds, we may be limited in our ability to incur additional indebtedness that may be needed for potential acquisitions and operations. Our inability to incur additional indebtedness could have a material adverse effect on our business, operating results and financial condition.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations is based on and should be read in conjunction with our consolidated financial statements and the accompanying notes beginning on page F-1 of this Annual Report on Form 10-K. Certain statements made in our discussion may be forward-looking. Forward-looking statements involve risks and uncertainties and a number of other factors that could cause actual results or outcomes to differ materially from our expectations. See “Forward-Looking Statements” at the beginning of this Annual Report on Form 10-K for additional discussion of some of these risks and uncertainties. Unless the context requires otherwise, when we refer to “we”, “us” and “our”, we are describing Orion Group Holdings, Inc. and its consolidated subsidiaries.

Overview

Orion Group Holdings, Inc., its subsidiaries and affiliates (hereafter collectively referred to as the “Company”), provide a broad range of specialty construction services in the infrastructure, industrial and building sectors throughout the continental United States, Alaska, and the Caribbean Basin. The Company’s marine segment services the infrastructure sector through marine transportation facility construction, marine pipeline construction, marine environmental structures, dredging of waterways, channels and ports, environmental dredging, design, and specialty services. Its concrete segment services the building sector by providing turnkey concrete construction services including place and finish, site preparation, layout, forming, and rebar placement for large commercial structural and other associated business areas. The Company is headquartered in Houston, Texas with offices throughout its operating areas.

Our contracts are obtained primarily through competitive bidding in response to “requests for proposals” by federal, state and local agencies and through negotiation and competitive bidding with private parties and general contractors. Our bidding activity and strategies are affected by factors such as our backlog, current utilization of equipment and other resources, job location, our ability to obtain necessary surety bonds and competitive considerations. The timing and location of awarded contracts may result in unpredictable fluctuations in the results of our operations.

Most of our revenue is derived from fixed-price contracts. We generally record revenue on construction contracts over time, measured by the percentage of actual contract costs incurred to date to total estimated costs for each contract. There are a number of factors that can create variability in contract performance and therefore impact the results of our operations. The most significant of these include the following:

● completeness and accuracy of the original bid;

● increases in commodity prices such as concrete, steel and fuel;

● availability and skill level of workers; and

● a change in availability and proximity of equipment and materials.

All of these factors can have a negative impact on our contract performance, which can adversely affect the timing of revenue recognition and ultimate contract profitability. We plan our operations and bidding activity with these factors in mind and they generally have not had a material adverse impact on the results of our operations in the past.

Our independent registered public accounting firm has included an explanatory paragraph describing the uncertainty about our ability to continue as a going concern in its report contained in this Annual Report. See “Liquidity and Capital Resources” below for more information.

2022 Recap and 2023 Outlook

In 2022, we recorded revenues of $748.3 million, of which $339.2 million was attributable to our marine segment and the remaining $409.1 million to our concrete segment. In addition, we ended 2022 with a consolidated backlog of $448.8

Table of Contents

million. Our revenues in 2022 increased by 24.4% as compared with 2021 and we recorded a net loss of $12.6 million, as compared with net loss of $14.6 million in the prior year.

Looking toward 2023, the Company continues to focus on developing opportunities across the infrastructure, industrial, and building sectors through organic growth.

Although to date the Company hasn’t experienced materially negative impacts from COVID-19, we have had and may continue to see some disruption to our operations due to variants of the COVID-19 virus that caused temporary increases in absenteeism rates among our workforce and other impacts to supply chains and labor markets.

Marine Segment

Demand for our marine construction services continues, given our differentiated capabilities and service offering within the space. We continue to see bid opportunities to help maintain and expand the infrastructure that facilitates the movement of goods and people on or over waterways. Cruise line capital expenditures have yet to recover significantly from the pullback due to COVID-19, however we anticipate that, with continued recovery of end customer demand, we will see renewed interest in capital improvements from these customers. Opportunities from local port authorities and private clients are expected to expand over the long-term due to the need to accommodate larger ships and deeper drafts because of the expanded Panama Canal. Though the pace of bidding opportunities from the U.S. Army Corps of Engineers slowed towards the end of 2022, significant approved funding for USACE projects leads us to believe that we will see this translate into an increase in bid opportunities as we progress through 2023. Additionally, bid opportunities related to coastal restoration funded through the Resource and Ecosystems Sustainability, opportunities under the Tourist Opportunities and Revived Economies of the Gulf Coast States Act (the “RESTORE Act”) may arise in 2023. The Coastal Protection and Restoration Authority (“CPRA”) has a $1.35 billion budget for fiscal 2023, and our capabilities are well-suited to win a portion of this spending. In addition to these, the $1.2 trillion Infrastructure Investment and Jobs Act contains billions of dollars allocated to ports and water infrastructure, bridges, and causeways. We believe our current equipment fleet will allow us to meet market demand for projects from both our public and private customers.

In the long-term, we see positive trends in demand for our services in our end markets, including:

● Continuing need to repair and improve degrading U.S. marine infrastructure;

● Opportunities related to the Infrastructure Investment and Jobs Act (IIJA).

Table of Contents

Concrete Segment

Demand for our concrete segment’s services continues, although timing of certain new project releases could be delayed as a result of inflation, labor concerns, supply chain delays and macroeconomic impacts. We currently see long-term demand for our concrete construction services in the Texas building sector as Texas’ major metropolitan areas, and expanding suburbs, continuously retain their positions as leading destinations for population and business growth. Population growth throughout our markets continues to drive new distribution centers, education facilities, office expansion, retail and grocery establishments, new multi-family housing units, and structural towers for business, residential or mixed-use purposes. The diversified Texas economy provides us with multiple sources of bid opportunities. Additional demand for concrete services in our markets could be provided by work as part of the federal infrastructure bill.

In the long-term, we see positive trends in demands for our services in our end markets, including:

●Population growth in the state of Texas driven by corporate relocations;

●Continued investment in warehouse/distribution space in our core markets;

●Potential opportunities related to the Infrastructure Investment and Jobs Act (IIJA).

Consolidated Results of Operations

Backlog Information

Our contract backlog represents our estimate of the revenues we expect to realize under the portion of contracts remaining to be performed. Given the typical duration of our contracts, which is generally less than a year, our backlog at any point in time usually represents only a portion of the revenue that we expect to realize during a twelve-month period. We have not been adversely affected by contract cancellations or modifications in the past, however we may be in the future, especially in economically uncertain periods.

Backlog as of the periods ended below are as follows (in millions):

The sequential decline in backlog was due to a lower book-to-bill ratio in the concrete segment which was driven by more disciplined bidding practices and an effort to reduce exposure to under-performing projects. We are optimistic in our end-markets and in the opportunities that are emerging across our various marketplaces as evidencedby the $2.4 billion of quoted bids outstanding at quarter end, of which over $582 million we are the apparent low bidder on or have been awarded contracts subsequent to the end of the fiscal year ended December 31, 2022.

These estimates are subject to fluctuations based upon the scope of services to be provided, as well as factors affecting the time required to complete the project. Backlog is not necessarily indicative of future results. In addition to our backlog under contract, we also have a substantial number of projects in negotiation or pending award at any given time. Delays in decisions on pending awards also have a negative impact on the timing and amount by which we are able to increase backlog.

Other (expense) income:

Year ended December 31, 2022 compared with year ended December 31, 2021

Contract Revenues. Contract revenues for the year ended December 31, 2022 of $748.3 million increased $146.9 million or 24.4% as compared to $601.4 million in the prior year period. The increase was primarily driven by the start of large jobs awarded in the second half of 2021 in the marine segment, higher volume in the concrete segment, and the impact from claims and unapproved change orders recognized related to work primarily incurred in previous periods.

Gross Profit. Gross profit was $50.7 million for the year ended December 31, 2022, compared to $41.0 million in the prior year period, an increase of $9.7 million or 23.9%. Gross profit in both periods was 6.8% of total contract revenues. The increase in gross profit dollars was primarily driven by the impact from claims and unapproved change orders recognized related to work primarily incurred in previous periods and the release of discretionary project bonuses.

Selling, General and Administrative Expense. SG&A expenses were $62.5 million for the year ended December 31, 2022, compared to $60.2 million in the prior year period,an increase of $2.3 million or 3.9%. As a percentage of total contract revenues, SG&A expenses decreased from 10.0% to 8.4% primarily due to higher revenues in the current period. The increase in SG&A dollars was driven primarily by severance, consulting fees related to the management transition and property tax true-ups in the current year period, partially offset by a decrease in ERP implementation expense.

Gain on Disposal of Assets, net. During the year ended December 31, 2022 and 2021, we realized $5.0 million and $11.4 million, respectively, of net gains on disposal of assets. Included in the prior year amount is a net gain of $6.7 million related to the sale of property in Tampa, Florida. See Note 6 in this form 10-K for a further description of the sale of property.

Other Income, net of Expense. Other expense primarily reflects interest on our borrowings, partially offset by interest income and non-operating gains or losses. Interest expense for the prior year period included $2.1 million related to the extinguishment of our term loan and related interest rate swaps.

Income Tax Expense. We recorded tax expense of $0.4 million in the year ended December 31, 2022, compared to tax expense of $0.5 million in the prior year period. Our effective tax rate for the year ended December 31, 2022 was (3.5)%, which differs from the federal statutory rate of 21% primarily due to the tax impact from the valuation allowance for current year activity, state income taxes and the non-deductibility of other permanent items.

Year ended December 31, 2021 compared with year ended December 31, 2020

Contract Revenues. Contract revenues for the year ended December 31, 2021 of $601.4 million decreased $108.5 million or 15.3% as compared to $709.9 million in the prior year period. The decrease was primarily driven by a reduction in project activity compared to the prior year in the marine segment as a result of reduced and/or delayed bid opportunities due to the continued impacts from COVID 19 on the industries in which we serve.

Gross Profit. Gross profit was $41.0 million for the year ended December 31, 2021, compared to $84.7 million in the prior year period, a decrease of $43.7 million or 51.6%. Gross profit in the period was 6.8% of total contract revenues as compared to 11.9% in the prior year period. The decrease in gross profit dollars and percentage was driven by the decreased activity and volumes which negatively impacted revenue and contributed to an under recovery of indirect costs primarily related to decreased labor and equipment utilization. We also incurred decreased project performance in our concrete segment.

Selling, General and Administrative Expense. Selling, general and administrative expenses were $60.2 million for the year ended December 31, 2021 compared to $65.1 million in the prior year period,a decrease of $4.9 million or 7.5%. As a percentage of total contract revenues, SG&A expenses increased from 9.3% to 10.0% primarily as a result of the reduced revenue noted above. The decrease in SG&A dollars was driven by a decrease in the current year period related to bonus expense, business development costs pursuant to timing of project pursuits and awards and travel related costs.

Gain on Disposal of Assets, net. During the year ended December 31, 2021 and 2020, we realized $11.4 million and $9.0 million, respectively, of net gains on disposal of assets. Included in the current year amount is a net gain of $6.7 million related to the sale of property in Tampa, Florida. Included in the prior year amount is a $2.9 million net gain on insurance recoveries.

Other Income, net of Expense. Other expense primarily reflects interest on our borrowings, partially offset by interest income and non-operating gains or losses. Interest expense for the current year period included $2.1 million related to the extinguishment of our term loan and related interest rate swaps.

Income Tax Expense. We recorded tax expense of $0.5 million in the year ended December 31, 2021, compared to tax expense of $2.0 million in the prior year period. Our effective tax rate for the year ended December 31, 2021 was (3.6)%, which differs from the federal statutory rate of 21% primarily due to the valuation allowance related to the current year net loss.

Revenues for our marine segment for the year ended December 31, 2022 were $339.2 million compared to $263.9 million for the year ended December 31, 2021, an increase of $75.3 million, or 28.5%. The increase was primarily driven by the start of large jobs awarded in the second half of 2021 and the impact from claims and unapproved change orders recognized related to work primarily incurred in previous periods.

Operating income for our marine segment for the year ended December 31, 2022 was $9.8 million, compared to operating income of $5.8 million for the year ended December 31, 2021, an increase of $4.0 million. Excluding the impact of the sale of property in Tampa, Florida in the prior year, operating income was $9.8 million for the year ended December 31, 2022, compared to an operating loss of $0.6 million for the year ended December 31, 2021, an increase of $10.5 million. This increase in operating income was primarily due to the increase in revenue noted above, the impact from claims and unapproved change orders recognized related to work primarily incurred in previous periods, the gain on the disposal of excess equipment and the release of discretionary project bonuses, partially offset by the increase in SG&A expense noted above.

Concrete Segment

Revenues for our concrete segment for the year ended December 31, 2022 were $409.1 million compared to $337.5 million for the year ended December 31, 2021, an increase of $71.6 million, or 21.2%. This increase was primarily driven by increased cubic yard production in light commercial projects.

Operating loss for our concrete segment for the year ended December 31, 2022 was $17.8 million, compared to $15.1 million for the year ended December 31, 2021, an increase in operating loss of $2.7 million. This increase in operating loss was primarily due to the decline in project profits due to write-downs on several projects in addition to unabsorbed indirect expenses related to additional project management labor expense, partially offset by the release of discretionary project bonuses.

Marine Segment

Revenues for our marine segment for the year ended December 31, 2021 were $263.9 million compared to $388.2 million for the year ended December 31, 2020, a decrease of $124.3 million, or 32.0%. The decrease was primarily attributable toa reduction in project activity compared to the prior year period.

Operating income for our marine segment for the year ended December 31, 2021 was $5.8 million, compared to operating income of $29.8 million for the year ended December 31, 2020, a decrease of $24.0 million. Excluding the impact of the sale of property in Tampa, Florida in the current year and the net gain on insurance recoveries and the recovery on a disputed receivable in the prior year operating loss was $0.6 million for the year ended December 31, 2021, compared to operating income of $26.1 million for the year ended December 31, 2020, a decrease of $26.7 million. This decrease in operating income was primarily due to the decrease in revenue noted above and related under recovery of indirect costs as a result of decreased labor and equipment utilization.

Concrete Segment

Revenues for our concrete segment for the year ended December 31, 2021 were $337.5 million compared to $321.8 million for the year ended December 31, 2020, an increase of $15.7 million, or 4.9%. This increase resulted from increased production volumes in the current year period.

Operating loss for our concrete segment for the year ended December 31, 2021 was $15.1 million, compared to $3.2 million for the year ended December 31, 2020, an increase in operating loss of $11.9 million. This increase in operating loss was primarily due to decreased project performance and lower margins on several projects during the 2021 period.

Critical Accounting Estimates

The consolidated financial statements contained in this report were prepared in accordance with U.S. GAAP. The preparation of these financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect both the Company’s carrying values of its assets and liabilities, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Although our significant accounting policies are described in more detail in Note 2 of the Notes to Consolidated Financial Statements; we believe the following accounting policies to be critical to the judgments and estimates used in the preparation of our financial statements:

● Revenue Recognition from Construction Contracts;

● Long Lived Assets;

● Income Taxes;

● Insurance Coverage, Litigation, Claims and Contingencies.

Revenue Recognition

Our revenue is derived from contracts to provide marine construction, dredging, turnkey concrete services, and other specialty services. Our projects are typically short in duration and usually span a period of less than one year. We determine the appropriate accounting treatment for each contract before work begins and generally record revenue on contracts over time.

Performance obligations are promises in a contract to transfer distinct goods or services to the customer and are the unit of account under Topic 606. Our contracts and related change orders typically represent a single performance obligation because individual goods and services are not separately identifiable and we provide a significantly integrated service. Revenue is recognized over time because control is continuously transferred to the customer. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the stand-alone selling price of each distinct good or service. Progress is measured by the percentage of actual contract costs incurred to date to total estimated costs for each contract. This method is used because management considers contract costs incurred to be the best available measure of progress on these contracts. These estimates are

Table of Contents

subject to uncertainties and require judgment. Estimates of contract costs include all direct costs, such as material and labor, and those indirect costs incurred that are related to contract performance such as payroll taxes and insurance. General and administrative costs are charged to expense as incurred. Upfront costs, such as incurring costs to mobilize personnel and equipment prior to satisfying a performance obligation are capitalized and amortized over the contract performance period.

These estimates consider historical performance, the complexity of the work to be performed, the estimated time to complete the project, and other economic factors such as inflation and market rates. Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements, may result in revisions to costs and reported revenue and are recognized in the period in which the revisions are determined. The effect of changes in estimates of contract revenue or contract costs is recognized as an adjustment to recognized revenue on a cumulative catch-up basis. When losses on uncompleted contracts are anticipated, the entire loss is recognized in the period in which such losses are determined. Revenue is recorded net of any sales taxes collected and paid on behalf of the customer, if applicable.

Long-Lived Assets

Our long-lived assets consist primarily of equipment used in our operations. Fixed assets are carried at cost and are depreciated over their estimated useful lives, ranging from one to 30 years, using the straight-line method for financial reporting purposes and accelerated methods for tax reporting purposes. The carrying value of our long-lived assets is evaluated periodically based on utilization of the asset and physical condition of the asset, as well as the useful life of the asset to determine if adjustment to the depreciation period or the carrying value is warranted. If events and circumstances such as poor utilization or deteriorated physical condition indicate that the asset(s) should be reviewed for possible impairment, we use projections to assess whether future cash flows, including disposition, on a non-discounted basis related to the tested assets are likely to exceed the recorded carrying amount of those assets to determine if an impairment exists. If we identify a potential impairment, we will estimate the fair value of the asset through known market transactions of similar equipment and other valuation techniques, which could include the use of similar projections on a discounted cash flow basis. We will report a loss to the extent that the carrying value of the impaired assets exceeds their fair values.

Income Taxes

We determine our consolidated income tax provision using the asset and liability method prescribed by U.S. GAAP, which requires the recognition of income tax expense for the amount of taxes payable or refundable for the current period and for deferred tax liabilities and assets for the future tax consequences of events that have been recognized in an entity’s financial statements or tax returns. We must make significant assumptions, judgments and estimates to determine our current provision for income taxes, our deferred tax assets and liabilities, and any valuation allowance to be recorded against any deferred tax asset. The current provision for income tax is based upon the current tax laws and our interpretation of these laws, as well as the probable outcomes of any tax audits. The value of any net deferred tax asset depends upon estimates of the amount and category of future taxable income reduced by the amount of any tax benefits that we do not expect to realize. The factors used to assess the likelihood of realization include our forecast of future taxable income exclusive of reversing temporary differences and carryforwards, future reversals of existing taxable temporary differences and available tax planning strategies that could be implemented to realize the net deferred tax assets.

We consider both positive and negative evidence when evaluating the need for a valuation allowance on our deferred tax assets in accordance with ASC 740. Available evidence includes historical financial information supplemented by currently available information about future years. Generally, historical financial information is more objectively verifiable than projections of future income and is therefore given more weight in our assessment. We consider cumulative losses in the most recent twelve quarters to be significant negative evidence that is difficult to overcome in considering whether a valuation allowance is required. Conversely, we consider a cumulative income position over the most resent twelve quarters, to be significant positive evidence that a valuation allowance may not be required.

Actual operating results and the underlying amount and category of income in future years could render current assumptions, judgments and estimates of recoverable net deferred taxes inaccurate, thus impacting our financial position and results of operations. We compute deferred income taxes using the liability method. Under the liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those

Table of Contents

temporary differences are expected to be recovered or settled. Under the liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertain tax positions in accordance with the provisions of the FASB’s ASC 740-10, which prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken, or expected to be taken, on our consolidated tax return. We evaluate and record any uncertain tax positions based on the amount that management deems is more likely than not to be sustained upon ultimate settlement with the tax authorities in the tax jurisdictions in which we operate.

Insurance Coverage, Litigation, Claims and Contingencies

We maintain insurance coverage for our business and operations. Insurance related to property, equipment, automobile, general liability and a portion of workers’ compensation is provided through traditional policies, subject to a deductible or deductibles. A portion of our workers’ compensation exposure is covered through a mutual association, which is subject to supplemental calls.

The marine segment maintains five levels of excess loss insurance coverage, totaling $200 million in excess of primary coverage. This excess loss coverage responds to most of its liability policies when a primary limit of $1 million has been exhausted; provided that the primary limit for Contingent Maritime Employer’s Liability is $10 million and the Watercraft Pollution Policy primary limit is $5 million. The concrete segment maintains five levels of excess loss insurance coverage, totaling $200 million in excess of primary coverage. This excess loss coverage responds to most of its liability policies when a primary limit of $1 million has been exhausted.

Separately, the Company’s marine segment employee health care is paid for by general assets of the Company and currently administered by a third party. The administrator has purchased appropriate stop-loss coverage. Losses on these policies up to the deductible amounts are accrued based upon known claims incurred and an estimate of claims incurred but not reported. The accruals are derived from known facts, historical trends and industry averages to determine the best estimate of the ultimate expected loss. Actual claims may vary from estimates. Any adjustments to such reserves are included in the Consolidated Results of Operations in the period in which they become known. The Company’s concrete segment employee health care is provided through two policies. A fully funded policy is offered primarily to salaried employees and their dependents while a partially self-funded plan with an appropriate stop-loss is offered primarily to hourly employees and their dependents. The self-funded plan is funded to the maximum exposure and, as a result, is expected to receive a partial refund after the policy expiration.

Liquidity and Capital Resources

Changes in working capital are normal within our business given the varying mix in size, scope and timing of delivery of our projects. At December 31, 2022, our working capital was $31.1 million, as compared with $36.2 million at December 31, 2021. As of December 31, 2022, we had unrestricted cash on hand of $3.8 million. Our borrowing capacity under our revolving credit facility at December 31, 2022 was approximately $6.0 million.

Our primary liquidity needs are to finance our working capital, fund capital expenditures, and pursue strategic acquisitions. Historically, our source of liquidity has been cash provided by our operating activities, sale of underutilized assets, and borrowings under our credit facilities. The assessment of the liquidity and going concern requires us to make estimates of future activity and judgments about whether we are compliant with financial covenant calculations under our debt and other agreements and have adequate liquidity to operate. Significant assumptions used in our forecasted model of liquidity include forecasted sales, costs, and capital expenditures; expected timing and proceeds of planned real estate transactions.

Going Concern

As described in Note 11 of Notes to Consolidated Financial Statements beginning on page F-1 of this Annual Report on Form 10-K, we had $35.0 million of outstanding indebtedness under our Credit Facility as of December 31, 2022 which matures on July 31, 2023. As of the date of these financial statements, our existing cash and cash equivalents are not sufficient to satisfy our operating cash needs for at least one year after the issuance of these financial statements.

Table of Contents

To alleviate these conditions, we are engaged in a syndication process to refinance the outstanding debt. Based on the advanced nature of our discussions, the completion of substantial due diligence by potential lenders, agreement among the parties on key terms of a new credit facility, and the expected timeline for documentation and execution of a new credit agreement, Management believes it will successfully complete a refinancing transaction prior to the maturity of the current credit facility. Additionally, we are exploring sales of underutilized assets as a source of liquidity.

Our ability to continue as a going concern is dependent on our ability to successfully refinance the credit facility, sale of underutilized assets and continue operations in forthcoming reporting periods. As our refinancing activities are ongoing, there can be no assurances that we will be able to secure financing on terms that are acceptable to us or at all.

These conditions raise substantial doubt about our ability to continue as a going concern within one year after the date the financial statements are issued. While management has developed and is in process to implement plans that management believes could alleviate in the future the substantial doubt that was raised, management concluded at the date of the issuance of the financial statements that substantial doubt exists as those plans are not within the control of management. Our consolidated financial statements do not include adjustments, if any, that may arise from the outcome of this uncertainty.

There is an explanatory paragraph included in the report of our independent registered public accounting firm describing the uncertainty about our ability to continue as a going concern, which is considered an event of noncompliance under our Credit Facility. Management has obtained a consent with respect to the delivery of annual financial statements with an audit opinion unqualified as to going concern from the Credit Facility lenders, and we are compliant with the financial covenants of the credit agreement.

The following table provides information regarding our cash flows and our capital expenditures for the years ending December 31, 2022, 2021 and 2020:

Cash flows provided by operating activities $ 9,565 $ 69 $ 46,032

Operating Activities. During 2022, we generated approximately $9.6 million in cash from our operating activities. The net cash inflow is comprised of $14.8 million of cash inflows from net income, after adjusting for non-cash items and $5.2 million of cash outflows related to changes in net working capital. The changes in net working capital, which are reflected as changes in operating assets and liabilities in our Consolidated Statements of Cash Flows, were primarily driven by a $4.7 million decrease in operating lease liabilities during the period and a $4.7 million outflow pursuant to the relative timing and significance of project progression and billings during the period, partially offset by a $4.1 million inflow related to an increase in our net position of accounts receivable and accounts payable plus accrued liabilities during the period and $0.1 million of other cash inflows.

During 2021, we generated approximately $0.1 million in cash from our operating activities. The net cash inflow is comprised of $8.2 million of cash inflows from net income, after adjusting for non-cash items and $8.1 million of cash outflows related to changes in net working capital. The changes in net working capital, which are reflected as changes in operating assets and liabilities in our Consolidated Statements of Cash Flows, were primarily driven by a $2.4 million outflow pursuant to the relative timing and significance of project progression and billings during the period, a $1.3

million outflow related to a decrease in our net position of accounts receivable and accounts payable plus accrued liabilities during the period and a $4.9 million decrease in operating lease liabilities during the period, partially offset by $0.5 million of other cash inflows.

During 2020, we generated approximately $46.0 million in cash from our operating activities. The net cash inflow is comprised of $46.5 million of cash inflows from net income, after adjusting for non-cash items, partially offset by $0.5 million of cash outflows related to changes in net working capital. The changes in net working capital, which are reflected as changes in operating assets and liabilities in our Consolidated Statements of Cash Flows, were primarily driven by a $6.5 million outflow pursuant to the relative timing and significance of project progression and billings during the period, a $5.4 million decrease in operating lease liabilities during the period and $1.3 million of other outflows, partially offset by a $12.7 million inflow related to a decrease in our net position of accounts receivable and accounts payable plus accrued liabilities during the period.

Investing Activities. Capital asset additions and betterments to our fleet were $14.6 million in 2022, as compared with $17.0 million and $14.7 million in 2021 and 2020, respectively. Proceeds from the sale of property and equipment were $4.9 million in 2022, as compared with $27.1 million and $5.9 million in in 2021 and 2020, respectively. The increase in proceeds from the sale of property and equipment for the year ended December 31, 2021 is primarily related to the sale of our property in Tampa, Florida.

Financing Activities.

During the year ended December 31, 2022, we drew down $24.0 million from our revolving line of credit. During the year ended December 31, 2022, we repaid $28.0 million on our revolving line of credit, had payments of $3.0 million on finance lease liabilities and incurred $0.7 million of loan costs related to the Ninth Amendment of the Credit Facility.

During the year ended December 31, 2021, we drew down $53.0 million from our revolving line of credit. During the year ended December 31, 2021, we repaid $19.0 million on our revolving line of credit.

During the year ended December 31, 2021, we fully extinguished the term loan portion of our Credit Facility, in part using proceeds from the sale of property in Tampa, Florida. The extinguishment of the term loan reduced our exposure to variability in interest rates and eliminated future loan amortization payment commitments. Concurrent with extinguishing the term loan, we canceled the remaining open position on our interest rate swap, resulting in a $1.3 million loss on the mark to market value of the swap at the date of termination. The $1.3 million was paid to the counterparty, cleared from the balance sheet as an interest rate swap liability, removed from Other Comprehensive Income and charged to interest expense during the year ended December 31, 2021. Further, the remaining $0.8 million of unamortized deferred debt issuance costs were charged to interest expense related to the early extinguishment of the term loan. There were no penalties incurred related to early payment of the term loan.

During 2020, we drew down $10.0 million from our revolving line of credit. Additionally, we repaid $41.0 million on our revolving line of credit, as well as made the regularly scheduled debt payment on the term loan of $3.8 million and an additional principal paydown of $3.4 million with proceeds from the sale of equipment.

Sources of Capital

• Consolidated Leverage Ratio

- Fiscal Quarter Ending December 31, 2022 and each Fiscal Quarter thereafter, maximum of 3.00 to 1.00

• Consolidated Fixed Charge Coverage Ratio

- Fiscal Quarter Ending December 31, 2022 and each Fiscal Quarter thereafter, minimum of 1.25 to 1.00.

See Note 11 of Notes to Consolidated Financial Statements beginning on page F-1 of this Annual Report on Form 10-K for further discussion on the Company’s Debt.

Bonding Capacity

We are often required to provide various types of surety bonds that provide additional security to our customers for our performance under certain government and private sector contracts. Our ability to obtain surety bonds depends on our capitalization, working capital, past performance and external factors, including the capacity of the overall surety market. At December 31, 2022, the capacity under our current bonding arrangement was at least $750 million, with approximately $175 million of projects being bonded. We are confident that our balance sheet and working capital position are sufficient to allow us to continue to access bonding capacity necessary to pursue and deliver projects.

Effect of Inflation

We are subject to the effects of inflation through increases in the cost of raw materials, and other items such as fuel, concrete and steel. Due to the relative short-term duration of our projects, we are generally able to include anticipated price increases in the cost of our bids.

Off Balance Sheet Arrangements

Currently our only off balance sheet arrangements are those discussed above under “Bonding Capacity” and those which arise in the normal course of business. These arrangements are not reasonably likely to have an effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources that is material to investors. See Note 17 of Notes to Consolidated Financial Statements beginning on page F-1 of this Annual Report on Form 10-K.

Recently Issued Accounting Pronouncements

See Note 2 of the Notes to the Financial Statements (Part IV, Item 15 of this Form 10-K) for further discussion.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, our results of operations are subject to risks related to fluctuations in commodity prices and fluctuations in interest rates. Historically, our exposure to foreign currency fluctuations has not been material and has been limited to temporary field accounts located in foreign countries where we perform work. Foreign currency fluctuations were immaterial in this reporting period.

Commodity price risk

We are subject to fluctuations in commodity prices for concrete, steel products and fuel. Although we routinely attempt to secure firm quotes from our suppliers, we generally do not hedge against increases in prices for commodity products. Commodity price risks may have an impact on our results of operations due to the fixed-price nature of many of our contracts, although the short-term duration of our projects may allow us to include price increases in the costs of our bids.

Interest rate risk

At December 31, 2022, we had $35.0 million in outstanding borrowings under our credit facility, with a weighted average ending interest rate of 9.91%. Based on the amounts outstanding under our credit facility as of December 31, 2022, a 100 basis-point increase in LIBOR (or an equivalent successor rate) would increase the Company’s annual interest expense by approximately $0.4 million.
