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, 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.

​

The current COVID-19 pandemic has affected and may continue to adversely affect our business and results of operations and financial condition.

In March of 2020, there was an outbreak of a pandemic, and the President of the United States declared the outbreak a national emergency. In response to the COVID-19 pandemic, federal, provincial, state, county and local governments and public health organizations and authorities around the world implemented a variety of measures intended to control the spread of the virus, including quarantines, “shelter-in-place,” “stay-at-home” and similar orders, travel restrictions, school closures, business curtailments and closures, social distancing and hygiene requirements, and other measures.

​

We provide a broad range of specialty construction services in the infrastructure, industrial and building sectors of the continental United States, Alaska, Canada and the Caribbean Basin, which are generally considered essential services exempt from many of the above measures. Since March 2020, when the World Health Organization declared the COVID-19 to be a global pandemic, we have continued to provide these services to our customers, but with added focused attention on the safety and health of our employees. However, the COVID-19 pandemic and related governmental and business responses has had and may continue to have an adverse effect on the markets we derive project opportunities from, our customers, and our operations. Several private sector markets from which we derive project opportunities have been and

14

Table of Contents

may continue to be impacted by the COVID-19 pandemic. Customers in these impacted markets have delayed and may continue to delay both near term and future projects due to macroeconomic factors driven by the COVID-19 pandemic. These delays have and may continue to negatively impact our ability to acquire new projects from increased competition due to fewer projects being available in the market place. Supply chains for materials incorporated into the building of our projects and for our equipment used to complete our projects have been and may continue to be impacted. Labor markets have been and may continue to be impacted by COVID-19 related government transfer payments and other pandemic related factors, which have and may continue to result in a lower workforce participation rate. Additionally, as a result of the pandemic and various governmental orders, we have altered our operations to allow for appropriate social distancing and hygiene, which has led to decreased efficiency and productivity in our workforce and our operations, and a significant number of our corporate employees have been working from home. We have had and may continue to see disruptions to our operations as variants of the COVID-19 virus cause increases in absenteeism rates among our workforce. In addition, management is focused on mitigating the effects of the COVID-19 pandemic, which has required and will continue to require a substantial investment of time, energy, resources and focus.

​

The extent to which the COVID-19 pandemic impacts us will depend on numerous evolving factors and future developments that are uncertain and that we are not able to predict, including: the severity of the virus; the duration and scope of the pandemic; the impact of the vaccines and their effectiveness against COVID-19 and its evolving variants; governmental, business, individual and other actions taken in response to the pandemic; the effect on our suppliers and disruptions to the global supply chain; the impact on economic activity; the extent and duration of the impact on consumer and business confidence and spending; the effect on our end-user customers; the effect of any closures or other changes in operations of our and our suppliers’, distributors’ and end-user customers’ facilities; the health of and the effect on our employees and our ability to meet staffing needs in our construction and other critical functions, particularly if employees become ill, are quarantined as a result of exposure, or are reluctant to show up for work; our ability to provide services, including as a result of travel restrictions, work from home requirements and arrangements, and other restrictions or changes in behavior or preferences for interactions; the effect on employee healthcare costs; restrictions or disruptions to transportation, including reduced availability of ground, sea or air transport; the ability of our end-user customers to pay for our services; the potential effects on our internal controls, including those over financial reporting, as a result of changes in working arrangements that are applicable to our employees and business partners; and the effect on our ability to access capital on favorable terms and continue to meet our liquidity needs, all of which are highly uncertain and cannot be predicted. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic recession that has occurred or may occur in the future.

​

We depend on continued growth in population in our geographic market areas in Texas to support residential and nonresidential construction for our concrete construction segment.

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 often times adversely affects economic growth, which ultimately limits the need for residential and nonresidential construction services in the areas we currently perform services.

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,

15

Table of Contents

we could incur substantial costs without receipt of any corresponding revenues. Delays by our customers in obtaining 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 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.

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 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

16

Table of Contents

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, 2021, we had a backlog of work to be completed on contracts totaling approximately $376.9 million in our marine segment and approximately $213.1 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

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.

17

Table of Contents

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.

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

19

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.

20

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 Dredging Act, the Jones Act, the Shipping Act and the Vessel Documentation Act 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 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 unregulated market.

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 2021, we recorded less than $0.1 million of expense for our self-insured portion of these liabilities. We believe our recorded self-insurance reserves 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

Our strategy of growing through strategic acquisitions may not be successful.

We may pursue growth through the acquisition of companies or assets that will enable us to broaden the types of projects we execute and also expand into new markets. We have completed several acquisitions and plan to consider strategic acquisitions in the future. We may be unable to implement this growth strategy if we cannot identify suitable companies or assets or reach agreement on potential strategic acquisitions on acceptable terms. Moreover, an acquisition involves certain risks, including:

21

Table of Contents

Future acquisitions may require us to obtain additional equity or debt financing, which may not be available on attractive terms. Moreover, to the extent an acquisition transaction financed by non-equity consideration results in additional goodwill, it will reduce our tangible net worth, which might have an adverse effect on our credit and bonding capacity.

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 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.

Our indebtedness requires significant debt service payments that could adversely affect our financial condition and prevent us from fulfilling our obligations under our indebtedness.

At December 31, 2021, our total indebtedness under the Credit Agreement was approximately $39.0 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:

We may incur additional indebtedness in the future under our existing Credit Agreement, 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 our existing Credit Agreement or under arrangements that may have terms and conditions at least as restrictive as those contained in our existing Credit Agreement. At December 31, 2021, available capacity to borrow on the revolving lines of credit was $9.3 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. Failure to secure a new credit facility could restrict our access to capital, which may prevent us from funding our operations or from engaging in certain transactions which might otherwise be considered beneficial to us. Additionally, rising interest rates may increase our cost of capital and, therefore, reduce the amount of capital available to fund our operations.

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.

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”), provides a broad range of specialty construction services in the infrastructure, industrial and building sectors of 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 pour and finish, dirt work, layout, forming, rebar, and mesh across the light 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 such factors 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.

2021 Recap and 2022 Outlook

In 2021, we recorded revenues of $601.4 million, of which $263.9 million was attributable to our marine segment and the remaining $337.5 million to our concrete segment. In addition, we ended 2021 with a consolidated backlog of $590.0 million. Our revenues in 2021 decreased by 15.3% as compared with 2020 and we recorded a net loss of $14.6 million, as compared with net income of $20.2 million in the prior year.

Looking toward 2022, the Company continues to focus on developing opportunities across the infrastructure, industrial, and building sectors through organic growth, greenfield expansion, and strategic acquisition opportunities.

The spread of COVID-19 has impacted the global economy, leaving supply chains disrupted. As the world uses tactics like “social distancing” and “stay at home orders” to slow and stop the spread of COVID-19, demand destruction has led to increased unemployment and to the weakening of consumer confidence. Although to date the Company hasn’t experienced materially negative impacts from COVID-19, such as widespread project stoppage/cancelations or a slowdown/stoppage of accounts receivables collections, any delays in the timing of future awards could create gaps in the Company’s project delivery schedule across quarterly periods.

​

Federal and State governments have increased spending as part of efforts to mitigate the impact of COVID-19 on the economy. The amount and timing of such spending will be directly impacted by the duration of required efforts to contain COVID-19 and the severity of the negative impacts created by the virus and its effect on the economy.

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. However, we have some concerns about the short-term outlook for and are closely monitoring the short and long-term cruise line capital expenditures as their current demand has been severely impacted by COVID-19. Further, while we currently see bid opportunities from our private sector energy-related customers as they expand their marine facilities related to the storage, transportation and refining of domestically produced energy, we recognize that the timing of project awards may be impacted as a result of volatility of oil prices due to COIVD-19 related uncertainties. Over the long-term, we expect to see bid opportunities in this sector from petrochemical-related businesses, energy exporters, and liquefied natural gas facilities. Opportunities from local port authorities will also remain over the long-term, many of which are related to the widened Panama Canal. 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 into 2022. We believe our current equipment fleet will allow us to better 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;

● Funding for highways and transportation under successor Acts to the FAST Act;

● Potential opportunities related to the federal infrastructure bill.

Concrete Segment

Demand for our concrete segment’s services continues, although timing of certain new project releases could be delayed as a result of COVID-19 related macroeconomic impacts. We currently see long-term demand for our concrete construction services in the Texas building sector as Texas’ four major metropolitan areas, and expanding suburbs, continuously retain

27

Table of Contents

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 the Dallas-Fort Worth region;

​

●COVID-19 driven shift of people moving from the inner cities to suburban areas;

​

●Potential opportunities related to the federal infrastructure bill.

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 increase in backlog during the quarter is primarily driven by new jobs we won. The general trend of declining backlog over the past year through June 2021 is due in significant part to headwinds created by the COVID-19 pandemic in certain end market sectors, which has slowed the timing of project awards. We, however, remain optimistic in our end-markets and in the opportunities that are emerging across our various marketplaces as evidencedby the $2.6 billion of quoted bids outstanding at quarter end, of which $138 million we are the apparent low bidder on or have been awarded contracts subsequent to the end of the fiscal year ended December 31, 2021.

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.

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 ("SG&A") 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. See Note 6 in this form 10-K for a further description of the sale of property. 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.

Year ended December 31, 2020 compared with year ended December 31, 2019

Contract Revenues. Contract revenues for the year ended December 31, 2020 of $709.9 million increased approximately 0.2% as compared to $708.4 million in the prior year period.

Gross Profit. Gross profit was $84.7 million for the year ended December 31, 2020, compared to $64.0 million in the prior year period, an increase of $20.7 million or 32.3%. Gross profit for the year ended December 31, 2020 was 11.9% of total contract revenues as compared to 9.0% in the prior year period. The increase in gross profit dollars and percentage were primarily driven by margin improvement on projects and efficiencies in labor and equipment utilization.

​

Selling, General and Administrative Expense. Selling, general and administrative ("SG&A") expenses were $65.1 million for the year ended December 31, 2020 compared to $61.0 million in the prior year period, an increase of $4.1 million, or 6.4%. As a percentage of total contract revenues, SG&A expenses increased from 8.7% to 9.3%. The increase in both dollars and percentage was primarily attributable to the increased accrual of the annual incentive compensation plan during the current year period as compared to the prior year period.

​

Gain on Disposal of Assets, net. During the year ended December 31, 2020, we realized $6.2 million of net gains on sales of assets and $2.9 million of net gains on insurance recoveries from involuntary dispositions of assets. This compared to realizing $1.8 million of net gains on the assets we sold during the 2019 comparative period.

Other Income, net of Expense. Other expense primarily reflects interest on our borrowings, partially offset by interest income and non-operating gains or losses.

​

Income Tax Expense.We recorded tax expense of $2.0 million for the year ended December 31, 2020, compared to tax expense of $1.9 million in the prior year period. Our effective tax rate for the year ended December 31, 2020 was 8.9%, which differs from the federal statutory rate of 21% primarily due to the movement in the valuation allowance for current year activity, state income taxes and the non-deductibility of other permanent items.

Segment Results

The following table sets forth, for the periods indicated, statements of operations data by segment, segment revenues as a percentage of consolidated revenues and segment operating income (loss) as a percentage of segment revenues. In connection with the preparation of the financial statements for the year ended December 31, 2021, the Company has identified and corrected certain immaterial errors in segment reporting for all periods presented. Specifically, certain corporate overhead costs previously recorded to the marine segment as part of operating income (loss) and allocated from the marine segment to the concrete segment below operating income in the other income (expense) line have been allocated from the marine segment to the concrete segment as part of the determination of operating income for each segment. These corrections resulted in an offsetting change in operating income (loss) for each segment of $12.9 million and $11.8 million for the years ended December 31, 2020 and December 31, 2019, respectively.

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.

Table of Contents

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.

Year ended December 31, 2020 compared with year ended December 31, 2019

Marine Segment

Revenues for our marine segment for the year ended December 31, 2020 were $388.2 million compared to $369.1 million for the year ended December 31, 2019, an increase of $19.1 million, or 5.2%.

Operating income for our marine segment for the year ended December 31, 2020 was $29.8 million, compared to operating income of $12.8 million for the year ended December 31, 2019, an increase of $17.0 million. This increase in operating income included $6.7 million of net gains on disposal of assets. Excluding the increase in net gains on disposal of assets, net operating income for our marine segment for the year ended December 31, 2020 was $21.7 million compared to operating income of $11.5 million for the year ended December 31, 2019, an increase of $10.2 million. This increase in operating income was primarily due to project execution related margin improvement and non-direct cost recovery compared to the prior year period.

Concrete Segment

Revenues for our concrete segment for the year ended December 31, 2020 were $321.8 million compared to $339.3 million for the year ended December 31, 2019, a decrease of $17.5 million, or 5.2%.

Operating loss for our concrete segment for the year ended December 31, 2020 was $3.2 million, compared to an operating loss of $10.6 million for the year ended December 31, 2019, a decrease in operating loss of $7.4 million. This decrease in operating loss was primarily due to the improvement in project margins.

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

We adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), on January 1, 2018, using the modified retrospective method. We recognized the cumulative effect of initially adopting Topic 606 guidance as an adjustment to the beginning balance of retained earnings. Contracts with customers that were not substantially complete in both our marine and concrete segments were evaluated in order to determine the impact as of the date of adoption. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

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.

32

Table of Contents

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. 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.

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.

33

Table of Contents

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 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

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 and borrowings under our credit facilities. The assessment of the liquidity and going concern requires the Company to make estimates of future activity and judgments about whether the Company has adequate liquidity to operate. Significant assumptions used in the Company's forecasted model of liquidity include forecasted sales, costs, and capital expenditures. Based on a careful assessment of these factors management believes that the Company will have adequate liquidity for its operations for at least the next 12 months.

​

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, 2021, our working capital was $36.2 million, as compared with $54.8 million at December 31, 2020. As of December 31, 2021, we had unrestricted cash on hand of $12.3 million. Our borrowing capacity at December 31, 2021 was approximately $9.3 million.

Ninth Amendment to Revolving Credit Facility

​

On March 1, 2022, we entered into an amended revolving line of credit and swingline loan agreement (the “Ninth Amendment”) to, among other things, waive covenant defaults, reset the revolver limit, implement an anti-cash hoarding provision and institute temporary covenant requirements. For further details of the Ninth Amendment, see Note 20 in the Notes to the Financial Statements (of this Form 10-K).

​

We expect to meet our future internal liquidity and working capital needs and maintain or replace our equipment fleet through capital expenditure purchases, leases and major repairs, from funds generated by our operating activities for at least the next 12 months. Although our line of credit is reduced, we believe our cash position is adequate for our general business requirements discussed above and to service our debt.

​

The following table provides information regarding our cash flows and our capital expenditures for the years ending December 31, 2021, 2020 and 2019:

Operating Activities. 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.

During 2019, we used approximately $0.7 million in cash from our operating activities. The net cash outflow is comprised of $30.1 million of cash inflows from net income, after adjusting for non-cash items and $30.8 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 $22.9 million increase in our net position of accounts receivable and accounts payable. The increases in accounts receivable and accounts payable were consistent with our increased project activity year over year. The year over year increase in accounts receivable is more pronounced than accounts payable due to the longer cycle times on the accounts receivable, which also include

retainage whereas accounts payable typically turn in 30 days. The changes in net working capital also included a net outflow of $5.2 million from the net change in costs and estimated earnings in excess of billings on uncompleted contracts, offset by the change in billings in excess of costs and estimated earnings on uncompleted contracts. These changes were driven by the timing and execution of the underlying projects.

Investing Activities. Capital asset additions and betterments to our fleet were $17.0 million in 2021, as compared with $14.7 million and $17.2 million in 2020 and 2019, respectively. Proceeds from the sale of property and equipment were $27.1 in the year ended December 31, 2021, as compared with $5.9 million in the year ended December 31, 2020. 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, 2021, we drew down $53 million from our revolving line of credit. During the year ended December 31, 2021 we repaid $19 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.

During 2019, we drew down $63.0 million from our revolving line of credit. Additionally, we repaid $49.0 million on this draw, as well as made regularly scheduled debt payments on the term loan of $3.0 million and an additional principal paydown of $18.2 million with proceeds from a sale-leaseback arrangement.

Sources of Capital

As of December 31, 2021, our available sources of capital consist of borrowing availability on our revolving line of credit of $9.3 million pursuant to our Credit Facility.

Financial covenants

​

Restrictive financial covenants under the Credit Facility include:

- Fiscal Quarter Ending March 31, 2022 - $2.6 million.

- Fiscal Quarter Ending June 30, 2022 - $7.7 million on a year-to-date basis.

- Fiscal Quarter Ending September 30, 2022 and each Fiscal Quarter thereafter, to not exceed 3.00 to 1.00.

- Fiscal Quarter Ending December 31, 2022 and each Fiscal Quarter thereafter, to not be less than 1.25 to 1.00.

​

In addition, the Credit Facility contains events of default that are usual and customary for similar arrangements, including non-payment of principal, interest or fees; breaches of representations and warranties that are not timely cured; violation of covenants; bankruptcy and insolvency events; and events constituting a change of control.

​

During the fourth quarter of 2021, the Company initiated discussions with the lead bank due to concerns it would not be in compliance with financial covenants. The Company executed the Ninth Amendment during March 2022. With the

36

execution of the aforementioned amendment, the Company obtained a waiver on the financial covenants as of December 31, 2021. See Note 11 in the Notes to the Financial Statements (of this 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, 2021, the capacity under our current bonding arrangement was at least $750 million, with approximately $110 million of projects being bonded. We believe our balance sheet and working capital position are sufficient to allow us to continue to access our bonding capacity.

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, 2021, we had $39.0 million in outstanding borrowings under our credit facility, with a weighted average ending interest rate of 2.38%. Based on the amounts outstanding under our credit facility as of December 31, 2021, 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.

Item 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)) are designed to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Based on management’s evaluation with the participation of our principal executive officer and principal financial officer, as of the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of December 31, 2021.

Our management, including our principal executive officer and principal financial officer, believes that the audited consolidated financial statements contained in this Annual Report on Form 10-K fairly present, in all material respects, our financial condition, results of operations and cash flows for the years presented in conformity with U.S. generally accepted accounting principles.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the year ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act). Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States. Our system of internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles and that receipts and expenditures are being made only in accordance with authorizations of our management; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated financial statements.

Management, under the oversight of our principal executive officer and principal financial officer, and Audit Committee, assessed the effectiveness of our internal control over financial reporting as of December 31, 2021 using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal control - An Integrated Framework (“2013 Framework”). Based on its assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2021 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance U.S. generally accepted accounting principles.

Our independent registered public accounting firm, KPMG LLP, who audited the consolidated financial statements included in this annual report, has audited the effectiveness of our internal control over financial reporting as of December 31, 2021. KPMG LLP’s report appears on page F-4 of this annual report on Form 10-K.

Inherent Limitations on Effectiveness of Controls

Our management, including the principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well-designed and implemented, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors

Orion Group Holdings, Inc.:

Opinion on the ConsolidatedFinancial Statements

We have audited the accompanying consolidated balance sheets of Orion Group Holdings, Inc. and subsidiaries (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes and financial statement scheduleII (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 7, 2022 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

​

Evaluation of estimated costs at completion for certain long-term, fixed-priced construction contracts

​

As discussed in Note 2 to the consolidated financial statements, contract revenue is recognized over time because control of the promised goods and services is continually transferred to the customer. Progress is measured by the percentage of actual costs incurred to date to the total estimated costs at completion. Contract costs include all direct costs, such as material and labor, and those indirect costs incurred that are related to contract performance. The Company reported contract revenues of $601.4 million, which included revenue related to long-term, fixed price construction contracts.

​

F-2

Table of Contents

We identified the evaluation of estimated costs at completion for certain long-term, fixed-priced construction contracts in the Marine segment as a critical audit matter. Evaluating the Company’s estimated costs at completion for contracts in progress involved auditor judgment given the variability and estimation uncertainty associated with costs of material and labor to be incurred over a long-term contract period.

​

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s revenue process, including controls over the estimation of costs to complete certain long-term, fixed-priced construction contracts. We evaluated the Company’s ability to estimate these amounts by comparing the Company’s previous estimates to actual results. We evaluated estimated costs at completion for certain in-progress contracts by:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

​

To the Stockholders and Board of Directors

Orion Group Holdings, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Orion Group Holdings, Inc. and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes and financial statement scheduleII (collectively, the consolidated financial statements), and our report dated March 7, 2022 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
