Risk Factor Summary

Below is a summary of the principal factors that may make an investment in IEA and our Common Stock speculative or risky. This summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found in "Item 1A. Risk Factors" and, should be carefully considered, together with other information in this Annual Report on Form 10-K and our other filings with the SEC before making an investment decision regarding IEA and our Common Stock.

Summary of Risks Related to IEA:

Our quarterly operating results may fluctuate significantly and constrain liquidity, falling below the expectations of securities analysts and investors, due to multiple factors including seasonality, spending patterns of our customers, adverse weather conditions, supply chain and labor market constraints, inflation and other factors, some of which are beyond our control, and may result in a decline in our stock price.

The future effects of the current COVID-19 pandemic and ongoing labor market and supply chain pressures are unknown and evolving, and could result in negative effects on our business, financial condition, results of operations and prospects.

Changes in United States (“U.S.”) trade policy, including the imposition of tariffs or bans on imports of certain foreign sourced goods, may have a material adverse effect on our business, financial condition, cash flows and results of operations.

Our business may be affected by delays, only some of which may be recovered through claims against project owners,
subcontractors, or suppliers, which could increase our costs, reduce profitability and have a material adverse effect on our financial results.

Our business is subject to physical hazards that could result in substantial liabilities and weaken our financial condition.

We are self-insured against certain potential liabilities.

Acquisition activity presents certain risks to our business, operations and financial position, and we may not realize the
financial and strategic goals contemplated at the time of a transaction.

If we are unable to attract and retain qualified managers and skilled employees, we will be unable to operate efficiently, which could reduce our revenue, profitability and liquidity.

The U.S. wind and solar industries benefit from tax and other economic incentives and political and governmental policies. A significant change in these incentives and policies could materially and adversely affect our business, financial condition, results of operations, cash flows and growth prospects.

Many of our customers are regulated by federal and state government agencies, and the addition of new regulations or
changes to existing regulations may adversely impact demand for our services and the profitability of those services.

Our fixed priced contracts and federal, state and local government contracts pose inherent risks, including inaccurate estimations of costs associated with the contracts, lack of funding from government sources, onerous terms and competitive bidding processes, all of which could impair our financial performance.

Amounts included in our backlog may not result in actual revenue or translate into profits. Our backlog is subject to
cancellation and unexpected adjustments and therefore is an uncertain indicator of future operating results.

We could incur substantial costs to comply with environmental, health, and safety laws and regulations and to address
violations of or liabilities created under these requirements.

We derive a significant portion of our revenue from a concentrated base of customers and rely on a limited number of
suppliers for certain equipment used in our projects. The loss of our significant customers, or reduced demand for our services, or the loss of our significant suppliers could impair our financial performance.

PART I


ITEM 1. BUSINESS


Business Overview


Infrastructure and Energy Alternatives, Inc., a Delaware corporation (‘‘IEA’’, the ‘‘Company’’, ‘‘we’’, ‘‘us’’, or ‘‘our’’) is a holding company that, through various subsidiaries, is a leading diversified infrastructure construction company with specialized energy and heavy civil expertise throughout the United States (“U.S.”). The Company specializes in providing complete engineering, procurement and construction (“EPC”) services throughout the U.S. for the renewable energy, traditional power and civil infrastructure industries. These services include the design, site development, construction, installation and restoration of infrastructure. Although the Company has historically focused on the wind industry, its recent acquisitions have expanded its construction capabilities and geographic footprint in the areas of environmental remediation, industrial maintenance, specialty paving, heavy civil and rail infrastructure construction, creating a diverse national platform of specialty construction capabilities. We believe we have the ability to continue to expand these services because we are well-positioned to leverage our expertise and relationships in the wind energy business to provide complete infrastructure solutions in all areas.

Our common stock trades on the NASDAQ Capital Market under the symbol ‘‘IEA’’. We were founded in 1947 as White Construction and we became a public company as Infrastructure and Energy Alternatives, Inc. in March 2018 when we merged with a special purpose acquisition company (a non-operating shell company).

2018 Company Highlights

Public Company - On March 26, 2018, we consummated a merger (the “Merger”) pursuant to an Agreement and Plan of Merger, dated November 3, 2017, by and among M III Acquisition Corporation (“M III”), IEA Energy Services, LLC (“IEA Services”), a Delaware limited liability company, Infrastructure and Energy Alternatives, LLC (the “Seller”), a Delaware limited liability company and the parent of IEA Services immediately prior to such time, and the other parties thereto, which provided for, among other things, the merger of IEA Services with and into a wholly-owned subsidiary of M III. See Note 2.Merger, Acquisitions and Discontinued Operations in the notes to the audited consolidated financial statements for more informationcompany. Our common stock trades on the MergerNasdaq Capital Market under the symbol ‘‘IEA’’, and certain of our warrants trade on the continuing ownership ofNasdaq Capital Market under the symbol ‘‘IEAWW’’.

Reportable Segments

    The Company by M IIIoperates its business in two reportable segments:

Renewables Segment

    The Renewables segment operates throughout the U.S. and Seller.

Acquisition of CCS, including Saiiaspecializes in providing complete engineering, procurement and construction (“EPC”) services for the ACC Companies - On September 25, 2018, we acquired Consolidated Construction Solutions I LLCrenewable energy, traditional power and civil infrastructure industries. In 2021, Engineering News-Record (“CCS”ENR”), a ranked IEA as the 2nd leading provider of environmental and industrial engineering services. The wholly-owned subsidiaries of CCS, Saiia LLC (“Saiia”)wind and the American Civil Constructors LLC (the “ACC Companies”) generally enter into long-term contracts with both government and non-government customers to provide8th leading provider of solar EPC services for environmental, heavy-civilbased on revenue. These services include the design, site development, construction, installation and mining projects. We believe our acquisitionrestoration of Saiia and the ACC Companies will provide IEA with a strong and established presence in the environmental and industrial engineering markets, enhanced civil construction capabilities and an expanded domestic footprint in less-seasonal Southeast, West and Southwest markets.infrastructure.


Acquisition of William Charles Construction Group, including Ragnar Benson - On November 2, 2018, we acquired William Charles Construction Group, including Ragnar Benson ("William Charles"), a leader in engineering and construction solutions for the rail infrastructure and heavy civil construction industries. We believe our acquisition of William Charles will provide IEA with a market leading position in the attractive rail infrastructure market and continue to bolster our further growth in the heavy civil and construction footprint across the Midwest and Southwest.

Industry Trends

Our industry is composed of national, regional and local companies in a range of industries, including renewable power generation, traditional power generation and the civil infrastructure industries. We believe the following industry trends will help to drive our growth and success over the coming years:



Renewable Power Generation

In recent years, we have maintained a tightheavy focus on construction of renewable power production capacity as renewable energy, particularly from wind and solar, has become widely accepted within the electric utility industry and has become a cost-effective solution for the creation of new generating capacity. We believe that this shift has occurred because renewable energy power generation has reached a level of scale and maturity that permits these technologies to now be cost-effective competitors to more traditional power generation technologies, including on an unsubsidized basis. Under many circumstances, wind and solar power production offer the lowest levelized cost of energy (i.e., the all-in cost of generating power, including construction and operating costs) of any technology. As a result, wind and solar power are among the leading sources of new power generation capacity in the U.S., and wind and utility-scale solar energy generation is projected to become even more cost-effective in coming years as technological improvements make wind turbines and photovoltaic cells (and other solar generating technologies) even more efficient.

Governmental policies focused on a clean environment and the desire to decrease U.S. dependence on foreign oil imports have created incentives historically for the development of renewable energy production capacity and have created demand for more domestic, environmentally sensitive electrical power production facilities, such as wind and solar collection farms. The federal government has offered tax credits for investments in renewable energy infrastructure and production of power from renewable sources. Other tax incentives available to the renewable energy industry include accelerated tax depreciation provisions, including bonus depreciation, for certain renewable energy generation assets, such as equipment using solar or wind energy. These incentives specify a five-year depreciable life for qualifying assets rather than the longer depreciable lives of many non-renewable energy assets. In addition to shorter depreciable lives, those assets qualifying for bonus depreciation benefit from significant allowable first-year depreciation.

In addition to federal policies that historically have favored power production from renewable sources, a number of states also have supported the expansion of renewable energy generating capacity. Currently, nearly 40 states, as well as the District of Columbia and four territories, have adopted renewable portfolio standards or goals. Similarly, we believe that many corporations and retail consumers are increasingly focused on obtaining energy from renewable sources and have become a significant driver of incremental demand for wind and solar energy production capacity.

The market for the development of utility-scale wind and solar power generation is expected to remain robust. The Annual Energy Outlook 2019 published by the U.S. Department of Energy in February 2019 projected the addition of approximately 72 gigawatts of new utility-scale wind and solar capacity from 2018 to 2021, which we estimate will drive more than $17.5 billion of construction. Although this demand is driven, in part, by accelerated, incremental investment in renewable power generation sources during the phase-out period for existing tax incentives, fundamental demand for renewable power construction-and particularly for utility-scale solar farms-is projected to remain strong thereafter. See Regulation and Environmental Matters below for further discussion of phase-out period.

Heavy Civil Construction

During 2018, heavy civil construction was only a small part of our business and accounted for less than 10% of our revenue. We believe that this will become a more significant part of our business in 2019 as a majority of the revenue of the Companies we acquired during 2018 is in this sector and we have maintained a reputation for high quality work. State and federal funding for this industry has been neglected for decades, but the near-term outlook on both state and federal levels has led usability to believe that spending for infrastructure may experience significant growth over the next few years. Not only do we believe that state and federal funding is likely to increase, but alternative methods of construction, such as public and private partnerships, have gained significant traction in the United States in recent years.

We have taken steps to enhance our heavy civil construction business through acquisitions to take advantage of these growth opportunities. We believe that our business relationships with customers in this sector are excellent and our strong reputation that we have built will provide us with the foundation to grow our revenue base in this business. Additionally, there is significant overlap in labor, skills and equipment needs between our renewable energy construction business and our heavy civil infrastructure business, which we expect will provide us with operating efficiencies as we continue to expand this sector. Our renewable energy experience provides us withthese services to leverage our expertise in working in difficult conditions and environments, which we believe will provide us with a competitive advantage when bidding for more complicated and often higher margin civil and infrastructure projects.




Environmental Remediation
Coal-fired power plants have significant and recurring environmental management needs, because they consistently generate various waste byproducts throughout the power generation process. The primary type of these waste byproducts are CCRs, commonly known as coal ash. According to the American Coal Ash Association, more than 107 million tons of coal ash were generated in 2016, and according to the U.S. Environmental Protection Agency (“EPA”), in 2015, coal ash was one of the largest types of waste in the U.S. Coal ash management is mission-critical to the daily operations of power plants, as they generally only have on-site storage capacity for three to four days of CCR waste accumulation.

According to the American Coal Ash Association, as of 2016, approximately 44% of coal ash generated was disposed of. According to the EPA, approximately 80% of coal ash that was disposed of in 2012 was disposed of on-site in ash ponds or landfills. As of 2016, the American Coal Ash Association estimated that more than 1.5 billion tons of coal ash existed in ash ponds and landfills around the country. The EPA also estimates that, as of 2012, there were over 1,100 active and inactive on-site ash ponds and landfills requiring remediation or closure. These sites are typically large and will require significant capital from their owners, as well as specialized environmental expertise, to monitor on an ongoing basis, remediate, relocate the waste or completely close in an environmentally sustainable way.

As a result of our recent acquisition of Saiia and their ability to build strong relationships in the environmental remediationwind energy business to provide additional infrastructure solutions to the Company intends to continue to increase its growth of this area as a part of our business. We believe that with Saiia's reputation and our cross-selling capabilities we will be able to capture further market share and facilitate more self-performing environmental remediation opportunities in other projects that we undertake.clean energy markets.


RailSpecialty Civil Segment

    
For more than 150 years,The Specialty Civil segment operates throughout the U.S. rail network has beenand specializes in a critical componentrange of the U.S. transportation systemservices that creates a diverse national platform of construction capabilities, including:

Environmental remediation services such as site development, environmental site closure, outsourced contract mining and economy. Today it carries approximately one-third of U.S. exports and delivers five million tons of freight and approximately 85,000 passengers each day. According to the 2017coal ash management services.
Rail Infrastructure Report Card, the private freight rail industry owns the vast majority of the nation’s rail infrastructure, and continues to make significant capital investment — $27.1 billion in 2015 — to ensure the network’s good condition. Despite this investment, U.S. rail still faces clear challenges, most notably in passenger rail, which faces the dual problems of aging infrastructure and insufficient funding.
Federal forecasts predict an approximate 40% increase in U.S. freight shipments, including by rail, by 2040. To prepare for the future, the U.S. Department of Transportation has worked with the transportation industry to draft the first National Freight Strategic Plan, which addresses impediments to the efficient flow of goods in support of the nation’s economy. The Fixing America’s Surface Transportation (FAST) Act requires the strategic plan be completed by 2017 and be updated every five years. Through the FAST Act, Congress created a new federally-funded, freight-focused competitive grant program. Fostering Advancements in Shipping And Transportation For The Long-Term Achievement of National Efficiencies (FASTLANE) grants are expected to provide $4.5 billion through 2020 to freight and highway projects of national or regional significance.

We believe that the acquisition of William Charles including Ragnar Benson, provides the Company with the ability to capitalize on the new rail infrastructure construction that will be required to support the increase in U.S. freight shipments.     

Electrical Power and High Voltage Opportunities

The U.S. electrical transmission and distribution infrastructure requires significant ongoing maintenance, upgrade and expansion to manage power line congestion and avoid delivery failures. Regional shifts in population and industry may also create pockets of demand for increased transmission and distributionservices such as planning, design, procurement, construction and upgrades. According to the DOE’s Annual Energy Outlook 2019 published in February 2019, significant new electricity generating capacity is expected to be added through 2050, allmaintenance of which must be connected to the existing electric grid.

Renewable energy generation projects, which are typically located in remote areas, often require investment in new transmission lines to interconnect with the electrical grid. Although we have outsourced our high-voltage electrical needs historically, we implemented a program during 2018 to upgrade our in-house capacity to complete this work and continually strive to increase the portion of our high-voltage electrical work which we self-perform. We believe that this transition will


afford us the opportunity to capture incremental margin on our projects and to provide enhanced service to our customers.

We believe that the same capabilities that we are building in order to self-perform high-voltage electrical work will enable us to capture incremental revenue by providing these services to others. With investment by utilities and transmission companies to modernize, secure and visually improve the existing transmission system expected to be strong over the coming years, we expect that our existing customer relationships and reputation will leave us well-positioned for growth in this sector.

Competitive Strengths

Our competitive strengths include:

Scale, Technical Expertise and Reputation in the Wind Industry. We are a national Tier 1 provider of wind energy infrastructure projects due to our established reputation for safe, high quality performance, reliable customer servicemajor railway and technical expertise. Because theintermodal facilities.

Heavy civil construction services such as road and development of wind energy projects is very technically demanding, industry participants have increasingly emphasized safety, high quality performance and technical reliability. Our management estimates thatbridge construction, costs represent only approximately 20% to 25% of total project cost, but construction-related risks pose the most significant threat to completion of the project. We have successfully completed over 200 wind projects over approximately the past 10 years. Our scale, experience and reputation gives us an advantage when competing for new work, both from existing and potential customers.

An Industry Leader in Safety Performance. Our industry-leading safety performance helps us enhance our reputation for high quality and reliability. Our management team strives to instill a corporate culture committed to health and safety. Our experience modification rate, a measure of our history and safety record as compared to other businesses in our industry, was 0.61 and our total recordable incident rate was 1.29 in 2018, both of which were significantly below the construction industry averages of 1.0 and 2.8, respectively, reported by the U.S. Department of Labor and U.S. Bureau of Labor Statistics 2017. In our experience, safety records are an important factor to customers in contracting for services and we believe that our exemplary safety record is a significant differentiator for us.

Strong Relationships With Leading Industry Players. Our business model has enabled us to hold a leading position in the wind, heavy civil, rail infrastructure and environmental remediation sectors of the construction industry by successfully winning key contracts and establishing strong relationships with many established developers and operators, as well as with other market leaders. These relationships have provided us with a recurring base of blue-chip utilityspecialty paving, industrial maintenance and other customers. We also have strong relationships with the leading original equipment manufacturers who produce the equipment for our contracts. In recent years, customers have come to emphasize reliabilitylocal, state and excellence in execution, as well as a strong safety record, in selecting their construction partners, and our track record and reputation has made us a provider of choice to those industry participants. We have completed projects with top U.S. developers or owners, who are market leaders in their sectors. Our longstanding relationships have enabled us to develop strong alliances with many of our customers and vendors, providing us with a strong base for expansion initiatives. We continually strive to further improve these relationships and enhance our status as a preferred vendor to our customers.government projects.

Ability to Respond Quickly and Effectively. The skills required to serve each of our end-markets are similar, which allows us to utilize qualified personnel across multiple end-markets and projects. We are able to respond quickly and effectively to industry and technological changes, demand fluctuations and major weather events by allocating our employees, fleet and other assets as and where they are needed, enabling us to provide cost effective and timely services for our customers. Additionally, we have a track record of successfully recruiting and retaining skilled labor, despite industry shortages.

Experienced Management Team. Our senior management team has over 175 years of combined experience and proven expertise in wind, heavy civil, rail infrastructure and environmental remediation, and a deep understanding of our customers and their requirements. Our senior management team plays a significant role in establishing and maintaining long-term relationships with our customers, supporting the growth of our business, integrating acquired businesses and managing the financial aspects of our operations.

Ability to Cross-Sell Our Product and Service Offerings. A majority of our wind customers also have other construction project requests, and a number of them are in active discussions with us for those projects. By leveraging our established relationships with our customers, we have realized additional revenues by selling products and services that our customers historically purchased from various other providers.


Self-Perform Capabilities. We have made substantial investments in our self-perform capabilities and, as a result, are able to self-perform across a large portion of the services that we deliver. We continue to seek opportunities to expand our self-perform capabilities and expect to transition to self-performing a majority of our high-voltage electrical work over the course of 2019. We believe that our technical expertise, project management experience and our highly skilled and stable work force, enables us to provide our customers with a compelling package of technical reliability, consistent execution and safety. In addition, our self-perform capabilities provide us with an opportunity to retain margin while better controlling scheduling of projects, potentially leading to greater operational efficiencies for us and enhanced reliability for our customers.

Customers


We have longstanding customer relationships with many established companies in the renewable energy, thermal power, petrochemical, environmental remediation, civil and industrial power industries, with a recurring base of blue-chip


utility customers, as well as with original equipment manufacturers that produce the equipment for our business. We have completed windrenewable projects withfor top U.S. developers orand owners, rail infrastructure projects with top tier railroads and heavy civil construction projects with topmany government agencies.


Our renewable projects are considered individual customers as generally each project's developer forms its own project legal entity. For the year ended December 31, 2021, our largest customers accounted for 7% of our consolidated revenues and our ten largest customers accounted for 37.2% of our consolidated revenues.     

Although we are not dependent upon any one customer in any year, a relatively small number of repeat customers constitute a substantial portion of our total revenues. Accordingly, our management iswe are responsible for developing and maintaining existing relationships with customers to secure additional projects and increase revenue from our current customer base. We believe that our strategic relationships with customers will result in future opportunities. Our management is also focused on pursuing growth opportunities with prospective new customers.

Our work is generally performed pursuant to contracts for specific projects or jobs that require the construction or installation of an entire complex of specified units within an infrastructure system. CustomersGenerally, customers are billed monthly throughout the completion of work on a project; however, some contracts provide for additional billing upon the achievement of specific completion milestones, which may increase the billing period to more than one month. SuchMany contracts may include retainage provisions under which, generally, from 5% to 10% of the contract price is withheld until the work has been completed and accepted by the customer. BecauseWe occasionally bring claims against project owners for additional costs that exceed the contract price or for amounts not included in the original contract price. Similarly, we may not be ablepresent change orders and claims to maintain our current revenue levels or our current level of capacitysubcontractors and resource utilization if we are not able to replace work from completed projects with new project work, we actively review our backlog of project work and take appropriate action to minimize such exposure.suppliers.


We believe that our industry experience, technical expertise and reputation for customer service, as well as the

Backlog

For companies in the construction industry, backlog can be an indicator of future revenue streams. Estimated backlog represents the amount of revenue we expect to realize beyond 2020 from the uncompleted portions of existing construction contracts, including new contracts under which work has not begun and awarded contracts for which the definitive project documentation is being prepared, as well as revenue from change orders and renewal options. Estimated backlog for work under fixed price contracts and cost-reimbursable contracts is determined based on historical trends, anticipated seasonal impacts, experience from similar projects and estimates of customer demand based on communications with our customers. These contracts are included in backlog based on the estimated total contract price upon completion. We expect to realize approximately 55.4% of our estimated backlog during 2019 and 44.6% during 2020 and beyond.

As of December 31, 2018 our total backlog was approximately $2.1 billion compared to $1.1 billion as of December 31, 2017. The $1.0 billion increase is primarily related to $833.7 million of backlog related to our acquisitions coupled with a $166.3 million increase in backlog related to our legacy IEA business. Based on historical trends in the Company’s backlog, we believe awarded contracts to be firm and that the revenue for such contracts will be recognized over the life of the project. Timing of revenue for construction and installation projects included in our backlog can be subject to change as a result of


customer delays, regulatory factors, weather and/or other project-related factors. These changes could cause estimated revenue to be realized in periods later than originally expected, or not at all. In the past, we have occasionally experienced postponements, cancellations and reductions on construction projects, due to market volatility and regulatory factors. There can be no assurance as to our customers’ requirements or the accuracy of our estimates. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings.

Backlog is not a term recognized under U.S. GAAP, although it is a common measurement used in our industry. Our methodology for determining backlog may not be comparable to the methodologies used by others. See ‘‘Risk Factors’’ for a discussion of the risks associated with our backlog.

Safety and Insurance/Risk Management

We strive to instill and enforce safe work habits in our employees, and we require that our employees participate in training programs relevant to their employment, including all those required by law. We evaluate employees in part based upon their safety records and the safety records of the employees they supervise. Our business units have established robust safety programs to encourage, monitor and improve compliance with safety procedures and regulations including, behavioral based safety, jobsite safety analysis, site-specific safety orientation, subcontractor orientation, site safety audits, accident and incident safety investigations, OSHA 30-hour and 10-hour training, drug and alcohol testing and regular trainings in fall protection, confined spaces, crane rigging and flagman, first aid, CPR and AED.

Our business involves the use of heavy equipment and exposure to potentially dangerous workplace conditions. While we are committed to operating safely and prudently, we are subject to claims by employees, customers and third parties for property damage and personal injuries that occur in connection with our work. We maintain insurance policies for worker’s compensation, employer liability, automobile liability, general liability, inland marine property and equipment, professional and pollution liability, excess liability, and director and officers’ liability. See Note 10. Commitments and Contingencies in the notes to the audited consolidated financial statements.

Our business subjects us to the risk of adverse site conditions and unfavorable weather. While we mitigate these risks contractually to the extent possible, market conditions prevent us from fully passing these risks to our customers, and there is not a robust insurance market to cover these risks. We mitigate these risks by developing reserves we believe to be appropriate for risks that cannot be contractually mitigated, and we are evaluating the feasibility and cost-effectiviness of obtaining additional insurance to protect the Company from significant losses caused by adverse weather.

Suppliers, Materials and Working Capital

Under many of our contracts, our customers provide the necessary materials and supplies for projects and we are responsible for the installation, but not the cost or warranty, of those materials. Under certain other projects, we purchase the necessary materials and supplies on behalf of our customers from third-party providers. We are not dependent upon any one vendor and have not experienced significant difficulty in obtaining project-related materials or supplies as and when required for the projects we manage.

We utilize independent contractors to assist on projects and to help manage our work flow. Our independent contractors typically provide their own vehicles, tools and insurance coverage. We need working capital to support seasonal variations in our business, such as the impact of weather conditions on external construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated spending to support related customer demand. See ‘‘Management’s Discussion and Analysis of Financial Condition and Results of Operations.’’

We bear some risk of increases in the price of materials and supplies used in the performance of our work, such as aggregate, reinforcing steel, cable, and fuel. These risks are managed contractually, by entering into contracts with suppliers that fix the price paid by the Company within the budget established for a project, or by passing the risk of commodity cost increases to the customer.
Competition


We compete with a number of companies in theour markets, in which we operate, ranging from small local independent companies to large national firms, and some of our customers employ their own personnel to perform some of the type of services we provide.
    


The primary factors influencing competition in our industry are price, reputation, quality and delivery, relevant expertise, adequate financial resources, geographic presence, high safety ratings and a proven track record of operational success. We believe that our national platform, track record of completion, relationships with vendors, strong safety record and access to skilled labor enables us to compete favorably in all of these factors. We also believe that our ability to provide unionized and non-unionized workforces across a national footprint allows us to compete for a broad range of projects. While we believe our customers consider a number of factors when selecting a service provider, they award most of their work through a bid process. We believe our safety record, experience, quality of service and price are often principal factors in determining which service provider is selected.


Seasonality


Our revenues and results of operations can be subject to seasonal and other variations. These variations are influenced by weather, customer spending patterns, bidding seasons, receipt of required regulatory approvals, permits and rights of way, project timing and schedules and holidays. See ‘‘IEA Management’s Discussion and Analysis of Financial Condition and Results of Operations-ImpactOperations-Significant Factors Impacting Results-Seasonality.’’

While we mitigate these risks contractually to the extent possible, market conditions may prevent us from fully passing these risks to our customers, and there is not a robust insurance market to cover some of these risks. For example, we have evaluated the feasibility of insurance products to mitigate weather risk, but we do not believe that the current insurance market offers commercially practicable solutions to protect us against significant losses caused by adverse weather.


RegulationSuppliers and Environmental MattersMaterials


    Under many of our contracts, our customers provide the necessary materials and supplies for projects, such as wind turbines and solar panels, and we are responsible for the installation, but not the cost or warranty of those materials. Under certain other projects, we purchase the necessary materials and supplies on behalf of our customers from third-party providers.

    We may utilize independent contractors to assist on projects and to help manage our work flow. Our independent contractors typically provide their own vehicles, tools and insurance coverage.

We bear some risk of increases in the price of materials and supplies used in the performance of our work, such as aggregate, reinforced steel, cable, and fuel. These risks are managed contractually, by entering into contracts with suppliers that

fix the price paid by the Company within the budget established for a project, by passing the risk of commodity cost increases to the customer, or by purchasing materials and supplies at the time of the issuance of the contract notice to proceed.
We are experiencing supply chain disruptions in our end markets related to the following issues;
Labor shortages at suppliers have increased delays of the production of certain materials, including but not limited to machinery, tools, copper, reinforced steel, solar panels and other items;
Shipping costs have increased significantly due to higher demand for products but fewer delivery options due to a reduction of truck drivers and rail cars;
Delayed sequencing in our projects related to the inability to determine specific delivery dates for key materials;
Cost increases for tax, tariffs and border controls for materials entering the U.S. from other countries; and
Bans on imports of certain goods from China, particularly of polysilicon covered by the Uyghur Forced Labor Prevention Act, which is a significant input in the production of solar panels. These bans could result in project delays and increased costs to us or our customers.

We continue to monitor these supply chain disruptions and other logistical challenges, global trade relationships (e.g., tariffs, sourcing restrictions) and other general market and political conditions (e.g., inflation, Ukraine conflict) with respect to availability and costs of certain materials and equipment necessary for the performance of our business and for materials necessary for our customers’ projects. For example, in the renewable energy market are experiencing supply chain challenges, resulting in delays and shortages of, and increased costs for, materials necessary for the construction of certain renewable energy projects in the near term, including as a result of sourcing restrictions related to solar panels manufactured in China. While we believe many of our renewable energy customers may be able to manage near-term supply chain disruptions better than their smaller competitors, these challenges could delay our customers’ ongoing projects or impact their future project schedules, which in turn could impact the timing of our projects. While these delays are not anticipated to result in exposure to liquidated damages or commodity risks, such delays could cause our customers to cancel projects as higher than expected costs impact their project profitability projections which could impact our profitability and cash flow.
Regulation

Our operations are subject to various federal, state, and federal laws that apply to businesses generally, includinglocal laws and regulations relatedincluding:

licensing, permitting and inspection requirements applicable to labor relations, wages,contractors, electricians and engineers;
regulations relating to worker safety and environmental protection.protection;

permitting and inspection requirements applicable to construction projects;
wage and hour regulations;
regulations relating to transportation of equipment and materials, including licensing and permitting requirements;
building and electrical codes; and
special bidding, procurement and other requirements on government projects.

We believe we have all material licenses and permits needed to conduct operations and that we are in material compliance with applicable regulatory requirements. However, we could incur significant liabilities if we fail to comply with applicable regulatory requirements.

Environmental and Climate Change Matters

We are also subject to numerous environmental laws, including the handling, transportation and disposal of non-hazardous and hazardous substances and wastes, as well as emissions and discharges into the environment, including discharges into air, surface water, groundwater and soil. We also are subject to laws and regulations that impose liability and cleanup responsibility for releases of hazardous substances into the environment.


We believe we have all material licenses and permits needed to conduct operations and that we are in material compliance with applicable regulatory requirements. However, we could incur significant liabilities if we fail to comply with applicable regulatory requirements. See ‘‘Risk Factors-We could incur substantial costs to comply with environmental, health, and safety laws and regulations and to address violations of liabilities under these requirements.’’

The potential impact of climate change on our operations is highly uncertain. Climate change may result in, among other things, changes in rainfall patterns, storm patterns and intensity and temperature levels. Our operating results are significantly influenced by weather and major changes in historical weather patterns could significantly impact our future operating results. For example, if climate change results in significantly more adverse weather conditions in a given period, we could experience reduced productivity and increases in certain other costs, which could negatively impact revenues and gross margins.

We are affected by environmental and climate change matters but as a Company, we are focused on building a greener future, one wind turbine and solar panel at a time. There’s no question that the increased production and usage of renewable energy is crucial to reducing greenhouse gas emissions worldwide. We are proud to support this collective mission by leveraging our in-house expertise to build reliable infrastructure across all phases of the renewable energy lifecycle. From power generation to delivery, we can handle it all. Since entering the renewable energy market, IEA has become one of the largest utility-scale wind farm contractors in the country, completing more than 257 wind and solar projects and generating more than 24.4 GW of renewable energy. It is our goal, as we continue to grow, to expand and refine our renewable energy infrastructure construction capabilities, while minimizing environmental impact at every stage.

Production Tax Credit (the ‘‘PTC’’) and Investment Tax Credit (‘‘ITC’’)

In light of changes in federal government priorities and the cost-competitiveness of wind and solar power production, certain of the tax credits for production of renewable energy are phasing out. The Consolidated Appropriations Act of 2016 (‘‘CAA’’), which contains certain federal tax incentives applicable to the renewable energy industry, provided for the gradual elimination of certain of these incentives. Currently,In December 2020, the federal government implemented an agreement that extended lapsed and expiring tax codebreaks. The extension provides thata one year extension of the production tax credit (the "PTC") for wind projects (the ‘‘PTC’’) applies to qualifyingat a 60% level for projects for which thethat begin construction commencement date was prior to January 1, 2020. The PTC was reduced by 20% for 2017, has been reduced by 40% for 2018,on or before December 31, 2021 and finally will be reduced by 60% for 2019. Similarly, a phase down ratetwo year extension of the26% solar investment tax credit (the ‘‘ITC’’"Solar ITC"), which is available in lieu of PTC, is available for wind projects: 30%projects that begin construction before January 1, 2023 and 22% ITC for solar projects commencingthat begin construction before 2017, 24%January 1, 2024 for all solar projects commencing in 2017, 18% for projects commencing in 2018 and 12% for projects commencing in 2019. Solar projects, however, will be eligible for an investment tax credit (the ‘‘Solar ITC’’) only.placed into service prior to December 31, 2025. The Solar ITC is 30% for projects commencing prior to 2020 and will be reduced to 26% for projects commencing in 2020 and to 22% for projects commencing in 2021. After 2021, the Solar ITC willpermanently remain at 10% for projects that commence priorin 2024 and onwards. On June 29, 2021, the Internal Revenue Service ("IRS") issued a notice which provides that projects that began construction in 2016-2019 have six years, and projects that began construction in 2020 have five years from the date construction began to 2022, but are placedbe placed-in-service to qualify for the PTC or ITC that was in service after 2023.

Additionally, although the enactment of the 2017 Tax Act in December 2017 did not modify the existing production tax credit and investment tax credit incentive structures, a base erosion and anti-abuse tax, or ‘‘BEAT’’ provision, contained in the 2017 Tax Act imposes a minimum tax on certain corporations, and only 80% of the value of any such corporation’s production or investment tax credits can be applied as a reduction to such corporation’s BEAT liability. Accordingly, this BEAT provision could reduce the incentive for certain taxable investors to invest in tax equity financing arrangements and could materially reduce the value and availability such tax credits, grants and incentives for certain participants and financing sources in the wind and solar industry. The 2017 Tax Act permits the immediate expensing of certain capital expenditures between

This new rule couldeffectively extends the amount of time that many projects will be less valuable than a dollar-for-dollar investment tax credit or production tax credit, given the reduced corporate income tax rate of 21%.

EmployeesHuman Capital Resources


The Company has a workforce of both union and non-union employees that allows us to work anywhere in the U.S. We have a scalable workforce, with approximately 2,600 peak employees. As of December 31, 2018,2021, we had approximately 2,250employed 835 salaried employees approximately 595and 2,883 hourly employees. The total number of whom were represented by unions or werepersonnel employed is subject to collective bargaining agreements. See Note 14. Employee Benefit Plansthe volume of specialty services and construction work in the notes to the audited consolidated financial statements, which are incorporated herein by reference.

We hire employeesprogress, as our employee base ranged from a numberlow of sources, including our industry, trade schools, colleges and universities. We attract and retain employees by offering a competitive salary, benefits package, opportunities for advancement and an exemplary safety record. We strive to offer a caring and stable work environment that enables our3,000 employees to improve their performance, and enhance their skills and knowledge. 5,600 employees during the year.

We believe that our corporateemployees are the most valuable resource in successfully completing our projects. We believe our ability to maintain sufficient, continuous work for hourly employees helps us to maintain a stable workforce with a loyalty to and an understanding of our policies and culture and core value system helps uscontributes to our strong performance, safety and quality record. Our talent acquisition team uses internal and external resources to recruit highly skilled and talented workers, and we encourage employee referrals for open positions. In addition, we have partnerships with technical schools where we recruit and hire craft employees.

We strive to employ a dynamic mix of people to create the strongest company possible. Our policy forbids discrimination in employment on the basis of age, culture, gender, national origin, sexual orientation, physical appearance, race or religion. We are an inclusive company with people of various backgrounds, experience, culture, styles and talents.

As part of our compensation philosophy, we believe that we must offer and maintain market competitive total compensation programs for our employees in order to attract and retain employees. superior talent. In addition to base wages, we provide annual bonus opportunities, a Company matched 401(k) Plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, flexible work schedules, and employee assistance programs.

We strive to develop and sustain a skilled labor advantage by providing on and off-site training programs, project management training, and leadership development programs. Our leadership development program is designed to further develop each participant’s leadership skills and requires program participants to challenge themselves and their peers as they progress.

We are committed to the health, safety and wellness of our employees, and we pride ourselves on workplace safety. We track and maintain several key safety metrics, which senior management reviews monthly and are included in the determination of the annual bonus, and we evaluate management on their ability to provide safe working conditions on job sites and to create a safety culture.

We continue to address the longer-term need for additional labor resources in our markets, as we address an aging workforce and longer-term labor availability issues, increasing pressure to reduce costs and improve reliability, and increasing duration and complexity of their capital programs. We believe these trends will continue, possibly to such a degree that demand for labor resources will outpace supply. Furthermore, the cyclical nature of our business can create shortages of qualified labor in those markets during periods of high demand. Our ability to capitalize on available opportunities is limited

ITEM 1A. RISK FACTORS


YouRisks Related to IEA

Our quarterly operating results may fluctuate significantly and constrain liquidity, falling below the expectations of securities analysts and investors, due to multiple factors including seasonality, spending patterns of our customers, adverse weather conditions, supply chain and labor market constraints, inflation and other factors, some of which are beyond our control, and may result in a decline in our stock price.

Our quarterly operating results are generally reduced in the first quarter of each year due to adverse seasonal weather changes and customer reductions in their expenditures and work order requests towards the end of the calendar year.Additionally, our quarterly operating results may generally fluctuate significantly from quarter-to-quarter because of several factors, including:

12


weather events, including seasonal adverse conditions and natural catastrophes;
labor availability and costs;
supply chain constraints due to labor shortages, COVID-19 impacts, customs and border control orders, other laws and international sanctions, or other worldwide manufacturing and shipping constraints;
constraints on our subcontractors to deliver equipment and services
profitability of our products and services, especially in new markets and due to seasonal fluctuations;
changes in interest rates;
impairment of goodwill or other long-lived assets;
macroeconomic conditions, both nationally and locally, such as inflation;
changes in consumer preferences and competitive conditions;
expansion to new markets; and
fluctuations in commodity prices.

The cumulative impact of these factors have impacted our liquidity and financial position in the past.Though we secured access to a significant line of credit in executing our Credit Agreement, there can be no assurances that our liquidity will not be negatively impacted from these factors.

In the future, we may require additional funds for operating purposes and may seek to raise additional funds through debt or equity financing. There is no assurance that this additional financing will be available, or if available, will be on reasonable terms. If our liquidity and capital resources were insufficient to meet our working capital requirements or fund our debt service obligations, we could face substantial liquidity problems, may not be able to generate sufficient cash to service all our indebtedness and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful. In the event we are not able to fund our working capital, we will not be able to implement or may be required to delay all or part of our business plan, and our ability to improve our operations, generate positive cash flows from operating activities and expand the business would be materially adversely affected.

The future effects of the current COVID-19 pandemic and ongoing labor market and supply chain pressures are unknown and evolving, and could result in negative effects on our business, financial condition, results of operations and prospects.

The COVID-19 pandemic is a constantly evolving situation that has adversely impacted economic activity and conditions worldwide. In particular, efforts to control the spread of COVID-19 have led to shutdowns, worker availability constraints, shortages or delays in the global supply chain and related increases in the costs of labor and goods.

The COVID-19 pandemic could continue to affect us in a number of other ways, including:

Delays in receiving permits resulting in unanticipated changes to construction schedules;
Inability to obtain bonding from our sureties due to tightening of credit markets;
Inability to properly staff our construction projects due to labor market shortages, quarantines and local ordinances;
Inability of customers to timely fund project obligations due to liquidity issues, financial uncertainties, or supply chain disruptions (including supply chain disruptions impacting a significant amount of equipment used in our projects that are sourced from China);
Inability of, or delays by, our subcontractors to deliver equipment and services; and

Each of the foregoing could cause project delays or terminations, force majeure events and prevent the financing of new projects by our customers, which could negatively impact our ability to recognize revenues, bill our customers for current costs or secure future business. There can be no assurances that our business, financial condition, liquidity or results of operations will not be negatively impacted by the future effects of COVID-19.

Changes in U.S. trade policy, including the imposition of tariffs or bans on imports of certain foreign sourced goods, may have a material adverse effect on our business, financial condition, cash flows and results of operations.

A significant amount of equipment used in our projects is sourced, most often by our customers, from China.Current bans on imports of certain goods from China, particularly of polysilicon covered by the Uyghur Forced Labor Prevention Act, which is a significant input in the production of solar panels, could result in project delays and increased costs to us or our customers. The ban on some imports relating to the production of solar panels, along with tariffs and border controls for materials entering the U.S. from other countries, could make it harder or more costly for our customers to secure products used
13


in the construction of our projects until alternative supply chain sources are identified and developed, which may in turn impact our results of operations, profitability, cash flows and growth prospects. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional discussion of tariffs and import bans.

Our business may be affected by delays, only some of which may be recovered through claims against project owners, subcontractors, or suppliers, which could increase our costs, reduce profitability and have a material adverse effect on our financial results.

Our projects involve challenging engineering, procurement and construction phases that may involve many parties. Delays on a particular project can arise from a number of events involving the customer, third parties and us, including delays in design and engineering; delays or difficulties in obtaining equipment and materials; schedule changes; failures to timely obtain permits or rights-of-way or to meet other regulatory requirements; delays due to epidemics and pandemics (including COVID-19); weather-related delays; and other governmental, market and political events, many of which are beyond our control.
We perform work under a variety of conditions, including, but not limited to, challenging and hard to reach terrain and difficult site conditions. Some of our contracts require that we assume the risk should carefully consideractual site conditions vary from those expected, and these projects may be at increased risk for delays.

Delays may result in the risks described below together withcancellation or deferral of project work (including through a customer and or third party’s assertion of force majeure, or our assertion of force majeure), which could lead to a decline in revenue from lost project work, or, for project deferrals, could cause us to incur costs which are not reimbursable by the customer, and may lead to personnel shortages on other information contained in this Annual Report on Form 10-K. Ifprojects scheduled to commence at a later date. In some cases, delays and additional costs may be substantial, and we may be required to cancel a project and/or compensate the customer for the delay. We may not be able to recover any of such costs.  Any such delays or cancellations or errors or other failures to meet customer expectations could result in damage claims substantially in excess of the risks below wererevenue associated with a project. Delays or cancellations could also negatively impact our reputation or relationships with our customers, which could adversely affect our ability to occur,secure new contracts and our business, financial condition, results of operations, profitability, cash flows and growth prospects could be adversely impacted, and the price of our common stock could decline.prospects.

Risks Related to IEA

Our business is seasonal and is affected by adverse weather conditions and the spending patterns of our customers, exposing us to variable quarterly results.

Some of our customers reduce their expenditures and work order requests towards the end of the calendar year. Adverse weather conditions, particularly during the fall and winter seasons, can also affect our ability to perform outdoor services in certain regions of North America. As a result, we generally experience reduced revenue in the first quarter of each calendar year. Natural catastrophes such as hurricanes or other severe weather could also have a negative effect on the economy overall and on our ability to perform outdoor services in affected regions or utilize equipment and crews stationed in those regions, which could negatively affect our results of operations, cash flows and liquidity.

Our 2018 results reflect the effect of multiple severe weather events on the Company's wind business that began late in the third quarter and continued into the fourth quarter. These weather conditions had a significant impact on the construction of six wind projects across South Texas, Iowa, and Michigan, resulting in additional labor, equipment and material costs as well as change orders. IEA is aggressively pursuing the collection of all amounts it is contractually owed due to weather-related delays, including collections on change orders resulting from force majeure provisions of certain customer


contracts, which generally compensate for the actual costs of weather-related delays. See Item 7. Management's Discussion and Analysis for further discussion of weather impact.

Our failure to recover adequately on claims against project owners, subcontractors or suppliers for payment or performance could have a material adverse effect on our financial results.


We occasionally bring claims against project owners for additional costs that exceed the contract price or for amounts not included in the original contract price. Similarly, we present change orders and claims to our subcontractors and suppliers. If we fail to properly document the nature of change orders or claims, or are otherwise unsuccessful in negotiating a reasonable settlement, we could incur reduced profits, cost overruns or a loss on the project. These types of claims can often occur due to matters such as owner-caused delays, changes from the initial project scope and adverse conditions, which result in additional cost, both direct and indirect, or from project or contract terminations. From time to time, these claims can be the subject of lengthy and costly proceedings, and it is often difficult to accurately predict when these claims will be fully resolved. When these types of events occur and unresolved claims are pending, we may invest significant working capital in projects to cover cost overruns pending the resolution of the relevant claims. A failure to promptlytimely recover on these types of claims could have a material adverse effect on our liquidity and financial results.

Our business may be affected by difficult work sites and environments, which could cause delays and/or increase our costs and reduce profitability.

We perform work under a variety of conditions, including, but not limited to, challenging and hard to reach terrain and difficult site conditions. Performing work under such conditions can result in project delays or cancellations, potentially causing us to incur additional, unanticipated costs, reductions in revenue or the payment of liquidated damages. In addition, some of our contracts require that we assume the risk should actual site conditions vary from those expected. Some of our projects involve challenging engineering, procurement and construction phases, which may occur over extended time periods. We may encounter difficulties in engineering, delays in designs or materials provided by the customer or a third party, equipment and material delivery delays, schedule changes, delays from customer failure to timely obtain rights-of-way, weather-related delays, delays by subcontractors in completing their portion of the project and other factors, some of which are beyond our control, but which affect our ability to complete a project as originally scheduled. In some cases, delays and additional costs may be substantial, and we may be required to cancel a project and/or compensate the customer for the delay. We may not be able to recover any of such costs. Any such delays or cancellations or errors or other failures to meet customer expectations could result in damage claims substantially in excess of the revenue associated with a project. Delays or cancellations could also negatively impact our reputation or relationships with our customers, which could adversely affect our ability to secure new contracts and our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our failure to properly manage projects, or project delays, may result in additional costs or claims, which could have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Certain of our engagements involve large-scale, complex projects that may occur over extended time periods. The quality of our performance on such a project depends in large part upon our ability to manage our client relationship and the project itself and to timely deploy appropriate resources, including third-party contractors and our own personnel. Our business, financial condition, results of operations, profitability, cash flows and growth prospects could be adversely affected if we miscalculate the resources or time needed to complete a project with capped or fixed fees, or the resources or time needed to meet contractual milestones. Additionally, delays on a particular project, including delays in designs, engineering information or materials provided by the customer or a third party, delays or difficulties in equipment and material delivery, schedule changes, delays from a customer’s failure to timely obtain permits or rights-of-way or to meet other regulatory requirements, weather-related delays, permitting delays, governmental, market, political and other factors, some of which are beyond our control, may result in the cancellation or deferral of project work, which could lead to a decline in revenue from lost project work, or, for project deferrals, could cause us to incur costs which are not reimbursable by the customer, and may lead to personnel shortages on other projects scheduled to commence at a later date.

In addition, some of our agreements require that we share in cost overages or pay liquidated damages if we do not meet project deadlines; therefore, any failure to properly estimate or manage cost or delays in the completion of projects, could subject us to penalties, which could adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects. Further, any defects or errors, or failures to meet our customers’ expectations could result in damage claims against us, and because of the substantial cost of, and potentially long lead-times necessary to acquire certain of the materials and equipment used in our complex projects, damage claims may substantially exceed the


amount we can charge for our associated services.

We have a significant amount of debt. Our substantial indebtedness could adversely affect our business, financial condition and results of operations and our ability to meet our payment obligations.

We have a significant amount of debt and substantial debt service requirements. This level of debt could have significant consequences on our future operations, including:

making it more difficult for us to meet our payment and other obligations;

our failure to comply with the financial and other restrictive covenants contained in our debt agreements, which could trigger events of default that could result in all of our debt becoming immediately due and payable;

reducing the availability of our cash flows to fund working capital, capital expenditures, acquisitions or strategic investments and other general corporate requirements, and limiting our ability to obtain additional financing for these purposes;

subjecting us to increased interest expense related to our indebtedness with variable interest rates, including borrowings under our credit facility;

limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to changes in our business, the industry in which we operate and the general economy;

placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged; and

preventing us from paying dividends.

Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations. Our ability to meet our payment and other obligations under our debt instruments depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that future borrowings will be available to us under our credit facility in an amount sufficient to enable us to meet our payment obligations and to fund other liquidity needs. If we are not able to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, sell assets, reduce or delay capital investments, or seek to raise additional capital, and some of these activities may be on terms that are unfavorable or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations.

Our credit facility imposes restrictions on us that may prevent us from engaging in transactions that might benefit us, including responding to changing business and economic conditions or securing additional financing, if needed.
The terms of our indebtedness contain customary events of defaults and covenants that prohibit us from taking certain actions without satisfying certain financial tests or obtaining the consent of the lenders. The restricted actions include, among other things:

making unfinanced capital expenditures;

engaging in transactions with affiliates;

buying back shares or paying dividends in excess of specified amounts;

making investments and acquisitions in excess of specified amounts;

incurring additional indebtedness in excess of specified amounts;

creating certain liens against our assets;

prepaying subordinated indebtedness;



engaging in certain mergers or combinations;

failing to satisfy certain financial tests; and

engaging in transactions that would result in a ‘‘change of control.’’

Our credit facility requires that we comply with a consolidated first lien leverage ratio. Should we be unable to comply with the terms and covenants of our credit facility, we would be required to obtain consents from our bank group, further modify our credit facility or secure another source of financing to continue to operate our business, none of which may be available to us on reasonable terms or at all. A default could also result in the acceleration of our obligations under the credit facility. To the extent we need additional financing, we may not be able to obtain such financing at all or on favorable terms, which may materially decrease our profitability, cash flows and liquidity.

We may be unable to obtain sufficient bonding capacity to support certain service offerings, and the need for performance and surety bonds may reduce our availability under our replacement credit facility.

Some of our contracts require performance and payment bonds. If we are not able to renew or obtain a sufficient level of bonding capacity in the future, we may be precluded from being able to bid for certain contracts or successfully contract with certain customers. In addition, even if we are able to successfully renew or obtain performance or payment bonds, we may be required to post letters of credit or other collateral security in connection with the bonds, which would only be obtainable if we have sufficient availability under our replacement credit facility and, if available, would reduce availability for borrowings under our facility. Furthermore, under standard terms in the surety market, sureties issue bonds on a project-by-project basis and can decline to issue bonds at any time or require the posting of additional collateral at any time. If we were to experience an interruption or reduction in the availability of bonding capacity as a result of these or any other reasons, we may be unable to compete for or work on certain projects that require bonding.

Our failure to comply with the regulations of OSHA and other state and local agencies that oversee transportation and safety compliance could adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

The Occupational Safety and Health Act of 1970, as amended, establishes certain employer responsibilities, including maintenance of a workplace free of recognized hazards likely to cause death or serious injury, compliance with standards promulgated by the Occupational Safety and Health Administration (‘‘OSHA’’) and various recordkeeping, disclosure and procedural requirements. Various standards, including standards for notices of hazards and safety in excavation and demolition work, may apply to our operations. We have incurred, and will continue to incur, capital and operating expenditures and other costs in the ordinary course of business in complying with OSHA and other state and local laws and regulations, and could incur penalties and fines in the future, including, in extreme cases, criminal sanctions.

While we have invested, and will continue to invest, substantial resources in occupational health and safety programs, our industry involves a high degree of operational risk, and there can be no assurance that we will avoid significant liability. Although we have taken what we believe to be appropriate precautions, we have had employee injuries in the past, and may suffer additional injuries in the future. Serious accidents of this nature may subject us to substantial penalties, civil litigation or criminal prosecution. Personal injury claims for damages, including for bodily injury or loss of life, could result in substantial costs and liabilities, which could materially and adversely affect our financial condition, results of operations or cash flows. In addition, if our safety record were to deteriorate, or if we suffered substantial penalties or criminal prosecution for violation of health and safety regulations, customers could cancel existing contracts and not award future business to us, which could materially adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.


Our business is subject to physical hazards that could result in substantial liabilities and weaken our financial condition.

Construction projects undertaken by us expose our employees to heavy equipment, mechanical failures, transportation accidents, adverse weather conditions and the risk of damage to equipment and property. These hazards can cause personal injuries and loss of life, severe damage to or destruction of property and equipment and other consequential damages and could lead to suspension of operations and large damage claims which could, in some cases, substantially exceed the amount we charge for the associated services. In addition, if serious accidents or fatalities occur, or if our safety records were to deteriorate, we may be restricted from bidding on certain work and obtaining new contracts and certain existing contracts could be terminated. Our safety processes and procedures are monitored by various agencies and ratings bureaus.


bureaus and our historical performance has been better than industry averages. There is, however, no guarantee that we can maintain this performance in the future. The occurrence of accidents in our business could result in significant liabilities, employee turnover, increase the costs of our projects, or harm our ability to perform under our contracts or enter into new customer contracts, all of which could materially adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our experience modification rate, a measure of our history and safety record as compared to other businesses in our industry, was 0.61 and our total recordable incident rate was 1.29 in 2018, both of which were significantly below the industry averages of 1.0 and 2.8, respectively, reported by the U.S. Department of Labor and U.S. Bureau of Labor Statistics 2017. While these standards are still below industry averages, the Company experienced a fatality at one of our work sites in 2018 and there is no guarantee, based on the hazards discussed above, that we can maintain these averages.


We are self-insured against certain potential liabilities.

Although we maintain insurance policies with respect to employer’s liability, general liability, auto and workers compensation claims, those policies are subject to deductibles or self-insured retention amounts of up to $500,000 per
14


occurrence. We are primarily self-insured for all claims that do not exceedare less than the amount of the applicable deductible/self-insured retention. In addition, for our employees not part of a collective bargaining agreement, we provide employee health care benefit plans. Our primary health insurance plan is subjectplans have a self-insurance component up to a deductible of $100,000specified deductibles per individual claim per year.

Our insurance policies include various coverage requirements, including the requirement to give appropriate notice. If we fail to comply with these requirements, our coverage could be denied.

Losses    Projected losses under our insurance programs are accrued based upon our estimates of the ultimate liability for claims reported and an estimate of claims incurred but not reported. Insurance liabilities are difficult to assess and estimate due to unknown factors, including the severity of an injury, the extent of damage, the determination of our liability in proportion to other parties and the number of incidents not reported. The accruals are based upon known facts and historical trends.

Acquisition activity presents certain risks to our business, operations and financial position, and we may not realize the financial and strategic goals contemplated at the time of a transaction.

We expect that the acquisitions will be an important part of our long-term growth strategy. Acquisitions are inherently risky and may not be successful. Successful execution following the closing of an acquisition is essential to achieving the anticipated benefits of the transaction. We have made acquisitions to expand into new markets and our acquisition strategy depends on our ability to complete and integrate the acquisitions. Mergers and acquisitions are inherently risky, and any mergers and acquisitions that we complete may not be successful. The process of integrating an acquired company’s business into our operations and investing in new technologiestransaction, but is challenging and may result in expected or unexpected operating or compliance challenges, which may require significant expenditures and a significant amount of our management’s attention that would otherwise be focused on the ongoing operation of our business.attention. The potential difficulties or risks of integrating an acquired company’s business include, among others:include:


the effect of the acquisition on our financial and strategic positionsfinancials, strategy, and our reputation;

risk that we fail to successfully implement our business plan for the combined business;

risk that webusiness, are unable to obtain the anticipated benefits of the acquisition, including synergies or economies of scale;

risk that wescale or are unable to complete development and/or integration of acquired technologies;

risk that the market does not accept the integrated product portfolio;portfolio, reducing shareholder value;

challenges in reconciling business practices, or in integrating product development activities, logistics or information technology and other systems;

challengessystems or in reconciling accounting issues, especially if an acquired company utilizes accounting principles different from those we use;issues;

retention risk with respect to key customers, suppliers and employees and challenges in retaining, assimilating and training new employees;

potential failure of theour due diligence processes to identify significant problems, liabilities or other shortcomings or


challenges of an acquired company, which could result in unexpected litigation, regulatory exposure, financial contingencies and known and unknown liabilities; and

challenges in complying with newly applicable laws and regulations, including obtaining or retaining required approvals, licenses and permits.


Our acquisitions may also result in the expenditure of available cash and amortization of expenses, any of which could have a material adverse effect on our operating results or financial condition. Investments in immature businesses with unproven track records and technologies have an especially high degree of risk, with the possibility that we may lose the value of our entire investments or incur additional unexpected liabilities. Large or costly acquisitions or investments may also diminish our capital resources and liquidity or limit our ability to engage in additional transactions for a period of time. All of the foregoing risks may be magnified as the cost, size or complexity of an acquisition or acquired company increases, or where the acquired company’s products, market or business are materially different from or more immature than ours, or where more than one integration is occurring simultaneously or within a concentratedshort period of time.


In addition, in the future we may require significant financing to complete an acquisition or investment, whether through bank loans, raising of debt, equity offerings, or otherwise. We cannot assure you that such financing options will be available to us on reasonable terms, or at all. If we are not able to obtain such necessary financing, it could have an impact on our ability to consummate a substantial acquisition or investment and execute our growth strategy. Alternatively, we may issue a significant number of shares as consideration for an acquisition, which would have a dilutive effect on our existing shareholders.stockholders.

If we are unable to attract and retain qualified managers and skilled employees, we will be unable to operate efficiently, which could reduce our revenue, profitability and liquidity.
 
Our business is labor intensive, and some of our operations experience a high rate of employee turnover. In addition, given the nature of the highly specialized work we perform, many of our employees are trained in, and possess, specialized technical skills that are necessary to operate our business and maintain productivity and profitability. At times of low unemployment rates in the areas we serve, including due to general labor market constraints, it can be difficult for us to find qualified and affordable personnel. We may be unable to hire and retain a sufficiently skilled labor force necessary to support
15


our operating requirements and growth strategy. Our labor and training expenses may increase as a result of a shortage in the supply of skilled personnel. We may not be able to pass these expenses on to our customers, which could adversely affect our profitability. Additionally, our business is managed by a number of key executive and operational officers and is dependent upon retaining and recruiting qualified management. Labor shortages, increased labor or training costs, or the loss of key personnel could materially adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional discussion of labor shortage trends.

The U.S. wind and solar industries benefit from tax and other economic incentives and political and governmental policies. A significant change in these incentives and policies could materially and adversely affect our business, financial condition, results of operations, cash flows and growth prospects.

The Consolidated Appropriations Act of 2016 (‘‘CAA’’) extended certain provisions of the Internal Revenue Code, which contains federal tax incentives applicable to the renewable energy industry. Currently, the tax code provides that the production tax credit for wind projects (the ‘‘PTC’’) applies to qualifying projects for which the construction commencement date was prior to January 1, 2020. The PTC was reduced by 20% for 2017, has been reduced by 40% for 2018, and finally will be reduced by 60% for 2019. Similarly, a phase down rate of the investment tax credit (the ‘‘ITC’’) in lieu of PTC is available for wind projects: 30% ITC for projects commencing before 2017, 24% for projects commencing in 2017, 18% for projects commencing in 2018 and 12% for projects commencing in 2019. Solar projects, however, will be eligible for an investment tax credit (the ‘‘Solar ITC’’) only. The Solar ITC is 30% for projects commencing prior to 2020 and is reduced to 26% for projects commencingprograms, discussed in 2020 and to 22% for projects commencing in 2021. After 2021, the Solar ITC will permanently remain at 10% for projects that commence prior to 2022, but are placed in service after 2023.

The PTC, ITC, Solar ITC and cash grant programItem 1. Business, provide material incentives to develop wind energy generation facilities and thereby impact the demand for our manufactured products and services. TheWhile the increased demand for our products and services resulting from the current credits and incentives may continue, until such credits or incentives lapse. Thethe failure of Congress to extend or renew these incentives beyond their current expiration dates could significantly delay the development of wind energy generation facilities and the demand for wind turbines, towers and related components. In addition, we cannot assure you that any subsequent extension or renewal of the PTC ITC,or Solar ITC or cash grant programprograms would be enacted prior to its expiration or, if allowed to expire, that any extension or renewal enacted thereafter would be enacted with retroactive effect. It is possible that these federal incentives will not be extended beyond their current expiration dates.expiration. Any delay or failure to extend or renew the PTC ITC,or Solar ITC or cash grant programprograms in the future could have a material adverse


impact on our business, results of operations, financial performance and future development efforts.


State renewable energy portfolio standards generally require state-regulated electric utilities to supply a certain proportion of electricity from renewable energy sources or devote a certain portion of their plant capacity to renewable energy generation. Typically, subject utilities comply with such standards by qualifying for renewable energy credits evidencing the share of electricity that was produced from renewable sources. Under many state standards, these renewable energy credits can be unbundled from their associated energy and traded in a market system allowing generators with insufficient credits to meet their applicable state mandate. These standards have spurred significant growth in the wind energy industry and a corresponding increase in the demand for our manufactured products. Currently, the majority of states and the District of Columbia have renewable energy portfolio standards in place and certain states have voluntary utility commitments to supply a specific percentage of their electricity from renewable sources. The enactment of renewable energy portfolio standards in additional states or any changes to existing renewable energy portfolio standards, or the enactment of a federal renewable energy portfolio standard or imposition of other greenhouse gas regulations may impact the demand for our products. We cannot assure you that government support for renewable energy will continue. The elimination of, or reduction in, state or federal government policies that support renewable energy could have a material adverse impact on our business, financial condition, results of operations, profitability, cash flows and growth prospects.


Many of our customers are regulated by federal and state government agencies, and the addition of new regulations or changes to existing regulations may adversely impact demand for our services and the profitability of those services.
    Many of our energy customers are regulated by the Federal Energy Regulatory Commission ("FERC"), and our utility customers are regulated by state public utility commissions. These agencies could change the way in which they interpret the application of current regulations and/or may impose additional regulations. Interpretative changes or new regulations having an adverse effect on our customers and the profitability of the services they provide could reduce demand for our services, which could adversely affect our results of operations, cash flows and liquidity.
    Any future restrictions or regulations that might be adopted could lead to operational delays, increased operating costs for our customers in the renewable industry, reduced capital spending and/or delays or cancellations of future renewable infrastructure projects, which could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our fixed priced contracts and federal, state and local government contracts pose inherent risks, including inaccurate estimations of costs associated with the contracts, lack of funding from government sources, onerous terms and competitive bidding processes, all of which could impair our financial performance.

We derive a significant portion of our revenue from fixed-price contracts. Under these contracts, we typically set the price of our services on a per unit or aggregate basis and assume the risk that certain costs associated with our performance may be greater than what we estimated. In addition, we enter into contracts for specific projects or jobs that may require the installation or construction of an entire infrastructure system or specified units within an infrastructure system, which are priced on a per unit basis. Profitability will be reduced if actual costs to complete each unit exceed our original estimates.
16



Revenues derived from fixed-price contracts that are recognized as performance obligations are satisfied over time (formerly known as the percentage-of-completion method), measured by the relationship of total cost incurred compared to total estimated contract costs (cost-to-cost input method). Contract revenue and total cost estimates are reviewed and revised on an ongoing basis as the work progresses. If estimated costs to complete the remaining work for the project exceed the expected revenue to be earned, the full amount of any expected loss on the project is recognized in the period the loss is determined. Our profitability is therefore dependent upon our ability to accurately estimate the costs associated with our services and our ability to execute in accordance with our plans. A variety of factors affect these costs, such as lower than anticipated productivity, conditions at work sites differing materially from those anticipated at the time we bid on the contract and higher costs of materials and labor. These variations, along with other risks inherent in performing fixed price contracts, may cause actual project revenue and profits to differ materially from original estimates. If actual costs exceed our estimates, we could have lower margins than anticipated, or losses, which could reduce our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Additionally, we derive a portion of our revenues from contracts with federal, state and local governments and their agencies and departments. These contracts are directly affected by changes in governmental spending and availability of adequate funding. Factors that could affect current and future governmental spending include: policy or spending changes implemented by current administrations, departments or other government agencies; governmental shutdowns, failure to pass budget appropriations, continuing funding resolutions or other budgetary decisions; changes, delays or cancellations of government programs or requirements; adoption of new laws or regulations that affect companies providing services; curtailment of the governments’ outsourcing of services to private contractors; or the level of political instability due to war, conflict, epidemics, pandemics or natural disasters.

Contracts with federal, state and local governments and their agencies and departments are often subject to various uncertainties, rules, restrictions, regulations, oversight audits and profit and cost controls. If we violate a rule or regulation, fail to comply with a contractual or other restriction or do not satisfy an audit, a variety of penalties can be imposed on us including monetary damages, withholding or delay of payments to us and criminal and civil penalties. In “qui tam” actions brought by individuals or the government under the U.S. Federal False Claims Act or under similar state and local laws, treble damages can be awarded. Government contracts may also contain unlimited indemnification obligations. In addition, most of our government clients may modify, delay, curtail, renegotiate or terminate contracts at their convenience any time prior to their completion.

Government contracts are awarded through a rigorous competitive process. Governments and their agencies have increasingly relied upon multiple-year contracts with multiple contractors that generally require those contractors to engage in an additional competitive bidding process for each task order issued under a contract. This process may result in us facing significant additional pricing pressure and uncertainty and incurring additional costs. Moreover, we may not be awarded government contracts because of existing policies designed to protect small businesses and under-represented minorities. Any of the foregoing events could negatively affect our results of operations, cash flows and liquidity.

Amounts included in our backlog may not result in actual revenue or translate into profits. Our backlog is subject to cancellation and unexpected adjustments and therefore is an uncertain indicator of future operating results.

Our backlog consists of the estimated amount of services to be completed from future work on uncompleted contracts or work that has been awarded with final contracts still being negotiated. It also includes revenue from change orders and renewal options. Most of our contracts are cancelable on short or no advance notice. Reductions in backlog due to cancellation by a customer, or for other reasons, could significantly reduce the future revenue that we actually receive from contracts in backlog. In the event of a project cancellation, we may be reimbursed for certain costs, but we typically have no contractual right to the total revenues reflected in our backlog.

Backlog amounts are determined based on target price estimates that incorporate historical trends, anticipated seasonal impacts, experience from similar projects and from communications with our customers. These estimates may prove inaccurate, which could cause estimated revenue to be realized in periods later than originally expected, or not at all. In the past, we have occasionally experienced postponements, cancellations and reductions in expected future work due to changes in our customers’ spending plans, as well as on construction projects, due to market volatility, regulatory and other factors. There can be no assurance as to our customers’ requirements or the accuracy of our estimates. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings. In addition, contracts included in our backlog may not be profitable. If our backlog fails to materialize,result in the recognition of revenue, our business, financial condition, results of operations, profitability, cash flows and growth prospects could be materially and adversely affected.

We may choose, or be required, to pay our subcontractors even if our customers do not pay, or delay paying us for the related services.


We use subcontractors to perform portions of our services. In some cases, we pay our subcontractors before our customers pay us for the related services. We could experience a material decrease in profitability and liquidity if we choose, or are required, to pay our subcontractors for work performed for customers that fail to pay, or delay paying us, for the related work.
17



Our subcontractors may fail to satisfy their obligations to us or other parties, or we may be unable to maintain these relationships, either of which may have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth prospects.

We depend on subcontractors to perform work on some of our projects. There is a risk that we may have disputes with subcontractors arising from, among other things, the quality and timeliness of the work they perform, customer concerns about our subcontractors, or our failure to extend existing work orders or issue new work orders under a subcontracting arrangement. If any of our subcontractors fails to deliver the agreed-upon supplies and/or perform the agreed-upon services on a timely basis, then our ability to fulfill our obligations as a prime contractor may be jeopardized. In addition, the absence of qualified subcontractors with whom we have satisfactory relationships could adversely affect our ability to perform under some of our contracts or the quality of the services we provide. Any of these factors could have a material adverse effect on our results of operations, cash flows and liquidity.

We also rely on suppliers to obtain the necessary materials for certain projects, and on equipment manufacturers and


lessors to provide us with the equipment we require to conduct our operations. Although we are not dependent on any single supplier or equipment manufacturer or lessor, any substantial limitation on the availability of required suppliers or equipment could negatively affect our operations. Market and economic conditions could contribute to a lack of available suppliers or equipment. If we cannot acquire sufficient materials or equipment, it could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Many of our customers are regulated by federal and state government agencies, and the addition of new regulations or changes to existing regulations may adversely impact demand for our services and the profitability of those services.

Many of our energy customers are regulated by the Federal Energy Regulatory Commission, or FERC, and our utility customers are regulated by state public utility commissions. These agencies could change the way in which they interpret the application of current regulations and/or may impose additional regulations. Interpretative changes or new regulations having an adverse effect on our customers and the profitability of the services they provide could reduce demand for our services, which could adversely affect our results of operations, cash flows and liquidity.

Any future restrictions or regulations which might be adopted could lead to operational delays, increased operating costs for our customers in the wind industry that could result in reduced capital spending and/or delays or cancellations of future wind infrastructure projects, which could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

We could incur substantial costs to comply with environmental, health, and safety laws and regulations and to address violations of or liabilities created under these requirements.

Our operations and products are subject to a variety of environmental laws and regulations in the jurisdictions in which we operate and sell products governing, among other things, air emissions, wastewater discharges, the use, handling and disposal of hazardous materials, soil and groundwater contamination, and employee health and safety, and product content, performance and packaging.safety. We cannot guarantee that we will at all times be in compliance with such laws and regulations and if we fail to comply with these laws and regulations or ourwith permitting and other requirements, we may be required to pay fines or be subject to other sanctions. Also, certain environmental laws can impose the entire or a portion of the costcosts of investigating and cleaning up a contaminated site, regardless of fault, upon any one or more of a number of parties, including the current or previous owner or operator of the site. These environmental laws also impose liability on any person who arranges for the disposal or treatment of hazardous substances at a contaminated site. Third parties may also make claims against owners or operators of sites and users of disposal sites for personal injuries and property damage associated with releases of hazardous substances from those sites.

Changes in existing environmental laws and regulations, or their application, could cause us to incur additional or unexpected costs to achieve or maintain compliance. The assertion of claims relating to on- or off-site contamination, the discovery of previously unknown environmental liabilities, or the imposition of unanticipated investigation or cleanup obligations, could result in potentially significant expenditures to address contamination or resolve claims or liabilities. Such costs and expenditures could have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth prospects.

We may not accurately estimate the costs associated with services provided under fixed price contracts, which could impair our financial performance.
We derive a significant portion of our revenue from fixed-price contracts. Under these contracts, we typically set the price of our services on a per unit or aggregate basis and assume the risk that certain costs associated with our performance may be greater than what we estimated. In addition, we enter into contracts for specific projects or jobs that may require the installation or construction of an entire infrastructure system or specified units within an infrastructure system, which are priced on a per unit basis. Profitability will be reduced if actual costs to complete each unit exceed our original estimates. If estimated costs to complete the remaining work for the project exceed the expected revenue to be earned, the full amount of any expected loss on the project is recognized in the period the loss is determined. Our profitability is therefore dependent upon our ability to accurately estimate the costs associated with our services and our ability to execute in accordance with our plans. A variety of factors affect these costs, such as lower than anticipated productivity, conditions at work sites differing materially from those anticipated at the time we bid on the contract and higher costs of materials and labor. These variations, along with other risks inherent in performing fixed price contracts, may cause actual project revenue and profits to differ from original estimates. As a result, if actual costs exceed our estimates, we could have lower margins than anticipated, or losses, which could reduce our business, financial condition, results of operations, profitability, cash flows and growth prospects.



We recognize revenue from installation/construction fixed price contracts using the percentage-of-completion method; therefore, variations of actual results from our assumptions may reduce our profitability.

We recognize revenue from fixed price contracts using the percentage-of-completion method, under which the percentage of revenue to be recognized in a given period is measured by the percentage of costs incurred to date on the contract to the total estimated costs for the contract. The percentage-of-completion method therefore relies on estimates of total expected contract costs. Contract revenue and total cost estimates are reviewed and revised on an ongoing basis as the work progresses. Adjustments arising from changes in the estimates of contracts revenue or costs are reflected in the fiscal period in which such estimates are revised. Estimates are based on management’s reasonable assumptions, judgment and experience, but are subject to the risks inherent in estimates, including unanticipated delays or technical complications. Variances in actual results from related estimates on a large project, or on several smaller projects, could be material. The full amount of an estimated loss on a contract is recognized in the period that our estimates indicate such a loss. Such adjustments and accrued losses could result in reduced profitability, which could negatively impact our liquidity and results of operations.

We derive a significant portion of our revenue from a concentrated base of customers and therely on a limited number of
suppliers for certain equipment used in our projects. The loss of a small number of our significant customers, or a reduction in theirreduced demand for our services, or the loss of our significant suppliers could impair our financial performance.

Our business is concentrated among relatively few customers, and a significant proportion of our services are provided on a project-by-project basis. Although we have not been dependent upon any one customer, our revenue could significantly decline if we were to lose a small number of our significant customers, or if a few of our customers elected to perform the work that we provide with in-house service teams. In addition, our results of operations, cash flows and liquidity could be negatively affected if our customers reduce the amount of business they provide to us, or if we complete the required work on non-recurring projects and cannot replace them with similar projects. Many of the contracts with our largest customers may be canceled on short or no advance notice. Any of these factors could negatively impact our results of operations, cash flows and liquidity. See Note 1. Business, Basis

Additionally, there are a limited number of Presentationavailable and Significant Accounting Policiessuitable suppliers for certain equipment used in our projects, including erection cranes. Our ability to secure equipment and Note 10. Commitments and Contingencies, in the notes to audited consolidated financial statements, included in Item 8.

A drop in the price of energy sources other than solar or wind energy would adversely affect our results of operations.

We believe that a customer’s decision to invest in solar or wind projects, as opposed to other forms of electric power generation, is to a significant degree driven by the levelized cost of energy production. Changes in technology or cost of commodities could lessen the appeal of wind-generated electricity and other renewables relative to other technologies for power generation. Similarly, government support for other forms of renewable or non-renewable power generation could make construction of wind and solar generating projects less attractive to customers economically. The ability of energy conservation technologies, public initiatives and government incentives to reduce electricity consumption could also lead to a reduction in the need for new generating capacity and in turn reduce demand for our services. If prices for electricity generated by wind or solar facilities are not competitive or demand for new production falls, our business, financial condition, results of operations, profitability, cash flows and growth prospects mayliquidity could be materially harmed.

Increases in the costs of fuel could reduce our operating margins.
The price of fuel needed to run our vehicles and equipment is unpredictable and fluctuates based on events outside our control, including geopolitical developments, supply and demand for oil and gas, actions by the oil and gas producers, war and unrest in oil producing countries, regional production patterns and environmental concerns. Any increase in fuel costs could materially reduce our profitability and liquidity because most of our contracts do not allow us to adjust our pricing for such expenses.

We maintain a workforce based upon current and anticipated workloads. We could incur significant costs and reduced profitability from underutilization of our workforce if we do not receive future contract awards,negatively impacted if these awardssuppliers cease operations or our relationships with these suppliers are delayed,otherwise cancelled or if there is a significant reduction in the level of work we provide.terminated without notice.

Our estimates of future performance and results of operations depend on, among other factors, whether and when we receive new contract awards, which affect the extent to which we are able to utilize our workforce. The rate at which we utilize our workforce is affected by a variety of factors, including our ability to manage attrition, our ability to forecast our need for services, which allows us to maintain an appropriately sized workforce, our ability to transition employees from completed projects to new projects or between internal business groups, and our need to devote resources to non-chargeable activities such as training or business development. While our estimates are based upon our good faith judgment, these estimates can be unreliable and may frequently change based on newly available information. In the case of large-scale


projects where timing is often uncertain, it is particularly difficult to predict whether and when we will receive a contract award. The uncertainty of contract award timing can present difficulties in matching our workforce size to our contract needs. If an expected contract award is delayed or not received, we could incur costs resulting from reductions in staff or redundancy of facilities, which could reduce our profitability and cash flows.


In the ordinary course of our business, we may become subject to lawsuits, indemnity or other claims, which could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

From time to time, we are subject to various claims, lawsuits and other legal proceedings brought or threatened against us in the ordinary course of our business. These actions and proceedings may seek, among other things, compensation for alleged personal injury, workers’ compensation, employment discrimination and other employment-related damages, breach of contract, property damage, environmental liabilities, multiemployer pension plan withdrawal liabilities, punitive damages and civil penalties or other losses, liquidated damages, consequential damages, or injunctive or declaratory relief. We may also be subject to litigation involving allegations of violations of the Fair Labor Standards Act and state wage and hour laws. In addition, we generally indemnify our customers for claims related to the services we provide and actions we take under our contracts, and, in some instances, we may be allocated risk through our contract terms for actions by our customers or other third parties.

Claimants may seek large damage awards and defending claims can involve significant costs. When appropriate, we establish reserves againstfor these items that we believe to be adequate in light of current information, legal advice and professional indemnity insurance coverage, and we adjust such reserves from time to time according to developments. See Note 10. CommitmentsFrom time to time claims may involve material amounts and Contingenciesnovel legal theories, and any insurance we carry may not provide adequate coverage to insulate us from material liabilities for these claims. Litigation may result in the notes to the audited consolidated financial statements, which are included in Item 8. We could experience a reduction in our profitabilitysubstantial costs and liquidity if our legal reserves are inadequate, our insurance coverage proves to be inadequate or becomes unavailable, or our self-insurance liabilities are higher than expected. The outcome of litigation is difficult to assess or quantify, as plaintiffs may seek recovery of very large or indeterminate amounts in these types of lawsuits or proceedings, and the magnitude of the potential loss may remain unknown for substantial periods of time. Furthermore, because litigation is inherently uncertain, the ultimate resolution of any such claim, lawsuit or proceeding through settlement, mediation, or court judgment could have a material adverse effect on our business, financial condition or results of operations. In addition, claims, lawsuits and proceedings may harm our reputation or divert management’s attention and resources from the operation of our business, or divert resources away from operating our business, and cause us to incur significant expenses, any of which could have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth prospects.results of operations.

Certain of our businesses have employees who are represented by unions or are subject toand collective bargaining agreements. The use of a unionized workforce and any related obligations could adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Certain of our employees are represented by labor unions and collective bargaining agreements. Although all such collective bargaining agreements prohibit strikes and work stoppages, we cannot be certain that strikes or work stoppages will not occur despite the terms of these agreements. Strikes or work stoppages could adversely affect our relationships with our customers and cause us to lose business. Additionally, as current agreements expire, the labor unions may not be able to negotiate extensions or replacements on terms favorable to their members, or at all, or avoid strikes, lockouts or other labor actions from time to time that may affect their members. Therefore, it cannot be assured that new agreements will be reached with employee labor unions as existing contracts expire, or on desirable terms. Any action against us relating to the union workforce we employ could have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our participation in multiemployer pension plans may subject us to liabilities that could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Substantially all of our union and collective bargaining agreements require us to participate with other companies in multiemployer pension plans. To the extent that U.S.-registered plans are underfunded defined benefit plans, the Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980 (collectively, ‘‘ERISA’’), which governs U.S.-registered multiemployer pension plans, subjects employers to substantial liabilities upon the employer’s complete or partial withdrawal from, or upon termination of, such plans. Under current law pertaining to employers that are contributors to U.S.-registered multiemployer defined benefit plans, a plan’s termination, an employer’s voluntary withdrawal from, or the mass withdrawal of contributing employers from, an underfunded multiemployer defined benefit plan requires participating employers to make payments to the plan for their proportionate


share of the multiemployer plan’s unfunded vested liabilities. These liabilities include an allocable share of the unfunded vested benefits of the plan for all plan participants, not only for benefits payable to participants of the contributing employer. As a result, participating employers may bear a higher proportion of liability for unfunded vested benefits if the other participating employers cease to contribute to, or withdraw from, the plan. The allocable portion of liability to participating employers could be more disproportionate if employers that have withdrawn from the plan are insolvent, or if they otherwise fail to pay their proportionate share of the withdrawal liability. We currently contribute, and in the past have contributed to, plans that are underfunded, and, therefore, could have potential liability associated with a voluntary or involuntary withdrawal from, or termination of, these plans. We currently do not have plans to withdraw from, and are not aware of related liabilities associated with these plans. However, there can be no assurance that we will not be assessed liabilities in the future. The Pension Protection Act of 2006 (the ‘‘PPA’’) requires that underfunded pension plans improve their funding ratios within prescribed intervals based on their level of underfunding, under which benefit reductions may apply and/or participating employers could be required to make additional contributions. In addition, if a multiemployer defined benefit plan fails to satisfy certain minimum funding requirements, the Internal Revenue Service (the ‘‘IRS’’) may impose on the employers contributing to such a plan a non-deductible excise tax of 5% of the amount of the accumulated funding deficiency.

Based upon the information available to us from plan administrators as of December 31, 2018, several of the multiemployer pension plans in which we participate are underfunded and, as a result, we could be required to increase our contributions, including in the form of a surcharge on future benefit contributions. The amount of additional funds we may be obligated to contribute in the future cannot be estimated, as these amounts are based on future levels of work of the union employees covered by these plans, investment returns and the level of underfunding of such plans.

Withdrawal liabilities, requirements to pay increased contributions, and/or excise taxes in connection with any of the multiemployer pension plans in which we participate could negatively impact our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our financial results are based, in part, upon estimates and assumptions that may differ from actual results.

In preparing our consolidated financial statements in conformity with U.S. GAAP, management makes a number of estimates and assumptions that affect the amounts reported in our consolidated financial statements. These estimates and assumptions must be made because certain information used in the preparation of our consolidated financial statements is either dependent on future events or cannot be calculated with a high degree of precision from data available. In some cases, these estimates are particularly uncertain and we must exercise significant judgment. Key estimates include: the recognition of revenue and project profit or loss, which we define as project revenue less project costs of revenue, including project-related depreciation, in particular, on long-term construction contracts or other projects accounted for under the percentage-of-completion method, for which the recorded amounts require estimates of costs to complete projects, ultimate project profit and the amount of probable contract price adjustments; allowances for doubtful accounts; estimated fair values of goodwill and intangible assets, acquisition-related contingent consideration, investments in equity investees; asset lives used in computing depreciation and amortization; accrued self-insured claims; share-based compensation; other reserves and accruals; accounting for income taxes; and the estimated impact of contingencies and ongoing litigation. Actual results could differ materially from the estimates and assumptions that we use, which could have a material adverse effect on our results of operations, cash flows and liquidity. See Note 1. Business, Basis of Presentation and Significant Accounting Policies in the notes to IEA’s audited consolidated financial statements, which is included in Item 8.

We may have additional tax liabilities associated with our domestic operations and discontinued Canadian operations.

We are currently subject to federal and state income taxes in the United States. Management must exercise significant judgment in determining our provision for income taxes due to lack of clear and concise tax laws and regulations in certain jurisdictions. Tax laws may be changed or clarified and such changes may adversely affect our tax provisions. We are audited by various U.S. tax authorities and in the ordinary course of our business there are many transactions and calculations for which the ultimate tax determination may be uncertain. In addition, we have certain ongoing audits and tax disputes with tax authorities in Canada. Although we believe that our tax estimates are reasonable and that we maintain appropriate reserves for our potential liability, the final outcome of tax audits and related litigation could be materially different from that which is reflected in our financial statements.


Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our financial condition and results of operations.

We will beare subject to federal and state income taxes in the United States, and our domestic tax liabilities will beare subject to the allocation of expenses in differing jurisdictions. Our future effective tax rates could be subject to volatility or adversely


affected by a number of factors, including:


changes in the valuation of our deferred tax assets and liabilities;

expected timing and amount of the release of any tax valuation allowances;

tax effects of stock-based compensation;

costs related to intercompany restructurings;

changes in tax laws, regulations or interpretations thereof; and

lower than anticipated future earnings in jurisdictions where we have lower statutory tax rates and higher than anticipated future earnings in jurisdictions where we have higher statutory tax rates.


In addition, we may be subject to audits of our income, sales and other transaction taxes by U.S. federal and state authorities. Outcomes from these audits could have an adverse effect on our financial condition and results of operations.

Warranty claims resulting from our services could have a material adverse effect on our business.

We generally warrant the work we perform for a two year period following substantial completion of a project, subject to further extensions of the warranty period following repairs or replacements. Historically, warranty claims have not been material, but such claims could potentially increase. If warranty claims occur, we could be required to repair or replace warrantied items at our cost, or, if our customers elect to repair or replace the warrantied item using the services of another provider, we could be required to pay for the cost of the repair or replacement. Additionally, while we generally require that the materials provided to us by suppliers have warranties consistent with those we provide to our customers, if any of these suppliers default on their warranty obligations to us, we may incur costs to repair or replace the defective materials for which we are not reimbursed. The costs associated with such warranties, including any warranty-related legal proceedings, could have a material adverse effect on our results of operations, cash flows and liquidity.


We rely on information, communications and data systems in our operations.

Systems and information technology interruptions and/or breaches in our data security could adversely affect our ability to operate and our operating results or could result in harm to our reputation.
    We are heavily reliant on computer, information and communications technology and related systems in order to operate.systems. From time to time, we may experience system interruptions and delays. Our operations could be interrupted or delayed, or our data security could be breached, if we are unable to add software and hardware, effectively maintain and upgrade our systems and network infrastructure and/or take other steps to improve the efficiency of and protect our systems. In addition, our computer and communications systems and operations could be damaged or interrupted by natural disasters, power loss, telecommunications failures, computer viruses, acts of war or terrorism, physical or electronic break-ins and similar events or disruptions, including breaches by computer hackers and cyber-terrorists. Any of these or other events could cause system interruptions, delays and/or loss of critical data including private data, could delay or prevent operations, including the processing of transactions and reporting of financial results, processing inefficiency, downtime, or could result in the unintentional disclosure of customer or our information, which could adversely affect our operating results, harm our reputation and result in significant costs, fines or litigation. Similar risks could affect our customers and vendors, indirectly affecting us. While management has taken steps to address these concerns by implementing network security and internal control measures, there can be no assurance that a system failure or loss or data security breach will not materially adversely affect our financial condition and operating results.


Risks Related to Our Capital Structure
We have a significant amount of debt. Our indebtedness could adversely affect our business, financial condition and results of operations and our ability to meet our payment obligations.
    We have a significant amount of debt and debt service requirements. This level of debt, and the covenants and restrictions associated with that debt, could have significant consequences on our future operations, including:

making it more difficult for us to meet our payment and other obligations;
19


our failure to comply with the financial and other restrictive covenants contained in our debt agreements, which could trigger events of default that could result in all of our debt becoming immediately due and payable;
reducing the availability of our cash flows to fund working capital, capital expenditures, acquisitions or strategic investments and other general corporate requirements, and limiting our ability to obtain additional financing for these purposes;
subjecting us to increased interest expense related to borrowings under our revolving senior secured credit facility;
limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to changes in our business, the industry in which we operate and the general economy;
placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged;
discouraging potential future acquisitions of us by a third party; and
preventing us from paying dividends.

    Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations. Our ability to meet our payment and other obligations under our debt instruments depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate positive cash flow from operations, or that future borrowings will be available to us under our Credit Agreement in an amount sufficient to enable us to meet our payment obligations and to fund other liquidity needs. If we are not able to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, sell assets, reduce or delay capital investments, or seek to raise additional capital, and some of these activities may be on terms that are unfavorable or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations.
Our Senior Unsecured Notes and Credit Agreement impose restrictions on us that may prevent us from engaging in transactions that might benefit us.

Our Senior Secured Notes contain restrictions that, among other things prevent or restrict us in certain circumstances from: incurring additional indebtedness; paying dividends or making other restricted payments; making loans and investments; incurring liens; selling assets; entering into affiliate transactions; entering into certain sale and leaseback transactions; entering into agreements restricting our subsidiaries' ability to pay dividends; and merging, consolidating or amalgamating or selling all or substantially all of our property.

Our Credit Agreement also contains certain standard financial covenants which, if not complied with, could have an adverse effect on our business, financial condition and liquidity. If our results of operations were negatively impacted by unforeseen factors, or impacted to a greater degree than anticipated, we might not be able to maintain compliance with the covenants and restrictions in our Credit Agreement. If we are unable to comply with the financial covenants in the future, and are unable to obtain a waiver or forbearance, it would result in an uncured default under the Credit Agreement, limiting our ability to borrow under it. A default under our Credit Agreement may also be considered a default under certain other of our instruments and contracts, including our Senior Unsecured Notes. If we were unable to borrow under the Credit Agreement, we would need to meet our capital requirements using other sources, if other sources would be available to us on reasonable terms, if at all.

Our variable rate indebtedness related to borrowings under our credit facility subjects us to interest rate risk and the transition away from LIBOR could have an adverse impact on us.

Borrowings under our credit facility are 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 if the amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. Additionally, financial markets are in the process of transitioning away from the London Interbank Offered Rate (LIBOR) to alternative benchmark rate(s), and such transition is scheduled to be complete by mid-2023. Our Credit Agreement contains LIBOR benchmark replacement provisions. However, at this time, there can be no assurance as to whether any alternative benchmark or resulting interest rates may be more or less favorable than LIBOR or any other unforeseen impacts of the discontinuation of LIBOR. As a result, the proposals or consequences related to this transition could have a material adverse effect on our debt service obligations, financing costs, liquidity, financial condition, results of operations or cash flows and could impair our access to the capital markets.

There may be future sales of our common stock or other dilution of our equity, including as a result of the exercise of our warrants, that could adversely affect the market price of our common stock. We additionally have the option to issue shares of our common stock instead of cash for future acquisitions.
We may agree to issue additional shares in connection with future acquisition or financing transactions, which could have the effect of diluting our earnings per share as well as our existing stockholders’ individual ownership percentages and could lead to volatility in our common stock price.We are not restricted from issuing additional common stock. Additionally, we have warrants may result in additional issuances of common stock. See Note 9. Earnings Per Share for further description on each type of warrant and possible dilution. The issuance of additional shares of our common stock in connection with future acquisitions, convertible securities or other issuances of our common stock, including restricted stock awards, restricted stock units and/or options, or otherwise, will dilute the ownership interest of our holders of our common stock. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock.

Our warrant repurchase program may not enhance long-term value and repurchases could increase the price and volatility of our common stock, and diminish our cash reserves.

On November 4, 2021, the Company’s Board of Directors authorized a repurchase program for the Company’s publicly traded warrants to purchase common stock, which trade on the Nasdaq under the symbol IEAWW.This repurchase program allows the Company to purchase up to $25.0 million of warrants, at prevailing prices, in open market or negotiated transactions, subject to market conditions and other considerations, beginning November 11, 2021, and it will end no later than the expiration of the warrants on March 26, 2023. The repurchase program does not obligate the Company to make any repurchases and it may be suspended at any time.

The timing and actual number of warrants repurchased depend on a variety of factors including price, corporate and regulatory requirements, available cash, and other market conditions. Warrant repurchases may not enhance shareholder value, as any warrants repurchased could affect the price of our common stock, increase their price volatility and could potentially reduce the market liquidity for our common stock.Additionally, repurchases under this repurchase program will diminish our cash reserves, which impacts our ability to support our operations and pursue possible future opportunities and acquisitions.

The Ares Parties may have the ability to influence certain corporate decisions through their significant ownership of Common Stock and the rights granted to them through our Stockholders Agreement with the Ares Parties.

On August 2, 2021, the Company closed an underwritten public offering, in which the following equity transactions were completed with the Ares parties and the Ares parties converted all of their Series A Preferred Stock into 2,132,273 shares of Common Stock; we issued to the Ares Parties 507,417 shares of Common Stock representing shares of Common Stock underlying warrants that the Ares Parties were entitled to pursuant to anti-dilution rights that are triggered upon conversion of the Series A Preferred Stock described above; we issued to the Ares Parties 5,996,310 shares of Common Stock for the exercise of warrants that were issued to the Ares Parties in connection with their original purchases of Series B Preferred Stock; and the Ares Parties purchased 3,185,039 additional shares of Common Stock as part of the public offering.

We entered into a Stockholders’ Agreement on August 2, 2021 with the Ares Parties (“Stockholders’ Agreement”).Pursuant to the Stockholders’ Agreement, the Ares Parties are entitled to designate two members of our Board for so long as the Ares Parties and their affiliates beneficially own more than or equal to 20% of our Common Stock, and one representative for as long as the Ares Parties and their affiliates beneficially own more than or equal to 10% of our Common Stock. Additionally, we agreed the Board would be comprised of a total of nine directors (including the Ares representatives) at IEA’s next annual or special meeting at which directors are elected.

While these are limitations on the Ares Parties rights under the Stockholders’ Agreement, the Ares Parties have the ability to influence corporate decisions, whether through Board representation or its significant holdings in our Common Stock. The interests of the Ares Parties, may not align with the interests of our other stockholders. The Ares Parties are in the business of making investments in companies and may acquire and hold interests in businesses that compete directly or indirectly with us or may also pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us.

Our Certificate of Incorporation, Bylaws and certain provision of Delaware law contain anti-takeover provisions that could impair a takeover attempt.
    As a Delaware corporation, anti-takeover provisions may impose an impediment to the ability of others to acquire control of us, even if a change of control would be of benefit to our stockholders. In addition, certain provisions of our Certificate of Incorporation and our Bylaws, also may impose an impediment or discourage others from a takeover.
    These provisions include:

a staggered board of directors providing for three classes of directors, which limits the ability of a stockholder or group to gain control of our board of directors;
a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;
a prohibition on stockholders calling a special meeting and the requirement that a special meeting of stockholders may only be called by (i) the chairman of our Board, (ii) our Chief Executive Officer, (iii) a majority of our Board, or (iv) directors designated by M III Sponsor subject to certain conditions set forth in the Third A&R Investor Rights Agreement; and
the requirement that changes or amendments to certain provisions of our Certificate of Incorporation or Bylaws must be approved by holders of at least two-thirds of the Common Stock and, in some cases under our Bylaws, 80% of the Common Stock. Additionally, M III Sponsor retains certain consent rights prior to our ability to amend our Certificate of Incorporation or bylaws to de-classify our Board or amend our director voting thresholds.
Our stock price has experienced significant volatility.
    Our stock price has exhibited substantial volatility in the past and may continue to fluctuate in response to a number of events and factors, including, but not limited to:

actual or anticipated quarterly operating results;
new developments and significant transactions;
the financial projections we provide to the public, and any changes to the projections or failure to meet the projections;
low daily trading volume;
22


impact of significant day trading activity;
changes in our credit ratings;
the public’s reaction to our press releases, other public announcements and filings with the SEC;
changes in financial estimates, recommendations and coverages by securities analysts;
media coverage of our business and financial performance;
trends in our industry;
significant changes in our management;
lawsuits threatened or filed against us; and
general economic conditions.

    Price volatility over a given period or a low stock price may result in a number of negative outcomes, including, but not limited to:

creating potential limitations on the ability to raise capital through the issuance of equity or equity linked securities;
impacting the value of our equity compensation, which affects our ability to recruit and retain employees;
difficulty complying with the listing standards of Nasdaq; and
increasing the risk of regulatory proceedings and litigation, including class action securities litigation

    If any of these outcomes were to occur, it could materially and adversely affect our business, financial condition, or results of operations, and the value of your investment.
Risks Related to Our Industry and itsOur Customers’ Industries

Economic downturns could reduce capital expenditures in the industries we serve, which could result in decreased demand for our services.

The demand for our services has been, and will likely continue to be,is cyclical in nature and vulnerable to general downturns in the U.S. economy. During economic downturns, our customers may not have the ability to fund capital expenditures for infrastructure, or may have difficulty obtaining financing for planned projects. In addition, uncertain or adverse economic conditions that create volatility in the credit and equity markets may reduce the availability of debt or equity financing for our customers, causing them to reduce capital spending. This has resulted, and in the future could result in cancellations of projects or deferral of projects to a later date. Such cancellations or deferrals could materially and


adversely affect our results of operations, cash flows and liquidity. These conditions could also make it difficult to estimate our customers’ demand for our services and add uncertainty to the determination of our backlog.

In addition, our customers are negatively affected by economic downturns that decrease the need for their services or the profitability of their services. During an economic downturn, our customers also may not have the ability or desire to continue to fund capital expenditures for infrastructure or may outsource less work. A decrease in related project work could negatively impact demand for the services we provide and could materially adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our customers may be adversely affected by market conditions and economic downturns, which could impair their ability to pay for our services.

Slowing conditions in the industries we serve, as well as economic downturns or bankruptcies within these industries, may impair the financial condition of one or more of our customers and hinder their ability to pay us on a timely basis. In difficult economic times, some of our clients may find it difficult to pay for our services on a timely basis, increasing the risk that our accounts receivable could become uncollectible and ultimately be written off. In certain cases, our clients are project-specific entities that do not have significant assets other than their interests in the project. From time to time, it may be difficult for us to collect payments owed to us by these clients. Delays in client payments may require us to make a working capital investment, which could negatively impact our cash flows and liquidity. If a client fails to pay us on a timely basis or defaults in making payments on a project for which we have devoted significant resources, it could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our industry is highly competitive, which may reduce our market share and harmimpact our financial performance.

We compete with other companies, in most of the markets in which we operate, ranging from small independent firms servicing local markets to larger firms servicing regional and national markets. We also face competition from existing and prospective customers that employ in-house personnel to perform some of the services we provide. Additionally, organizations that have adequate financial resources and access to technical expertise and skilled personnel may become a competitor. Most of our customers’ work is awarded through a bid process. Consequently, although management believes reliability is often more important to customers than price, price is often thea principal factor that determines which service provider is selected, especially on smaller, less complex projects. Smaller competitors sometimes win bids for these projects based on price alone due to their lower costs and financial return requirements. Additionally, our bids for certain projects may not be successful because of a customer’s perception of our relative ability to perform the work as compared to our competitors or a customer’s perception of technological advantages held by our competitors as well as other factors. Our business, financial condition, results of operations, profitability, cash flows and growth prospects could be materially and adversely affected if we are unsuccessful in bidding for projects or renewing our contracts, or if our ability to win such projects or agreements requires that we accept lower margins.


Many of the industries we serve are subject to customer consolidation, rapid technological and regulatory changes, and our inability or failure to adjust to our customers’ changing needs could result in decreased demand for our services.

We derive a substantial portion of our revenue from customers in the heavy civil and power generation industries, which are subject to consolidation, rapid changes in technology and governmental regulation. Consolidation of any of our customers, or groups of our customers, could result in the loss of one or more of these customers, or could affect customer demand for the services we provide. Additionally, changes in technology may reduce demand for the services we provide.

New technologies or upgrades to existing technologies by customers could reduce demand for our services. Technological advances may result in lower costs for sources of energy, which could render existing renewable energy projects and technologies uncompetitive or obsolete. Our failure to rapidly adopt and master new technologies as they are developed in any of the industries we serve could have a material adverse effect on our results of operations, cash flows and liquidity. Furthermore, certain of our customers face stringent regulatory and environmental requirements and permitting processes as they implement plans for their projects, any of which could result in delays, reductions and cancellations of projects, which could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Risks Related to Our Company and Our Common Stock

There may be future sales of our common stock or other dilution of our equity that could adversely affect the market price of our common stock. In connection with certain completed acquisitions, we have issued shares of our common stock, and


we additionally have the option to issue shares of our common stock instead of cash as consideration for future earn-out obligations.

We may agree to issue additional shares in connection with other future acquisition or financing transactions, which, if issued, would dilute your share ownership and could lead to volatility in our common stock price. We grow our business organically as well as through acquisition. One method of acquiring companies or otherwise funding our corporate activities is through the issuance of equity securities. In connection with certain acquisitions, we have the option to issue shares of our common stock instead of paying cash for the related earn-out obligations. Such issuances could have the effect of diluting our earnings per share as well as our existing shareholders’ individual ownership percentages and could lead to volatility in our common stock price.

We are not restricted from issuing additional common stock. The issuance of additional shares of our common stock in connection with future acquisitions, convertible securities or other issuances of our common stock, including restricted stock awards, restricted stock units and/or options, or otherwise, will dilute the ownership interest of our common shareholders. Sales of a substantial number of shares of our common stock or other equity-related securities in the public market could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity or equity-linked securities. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock.

The market price of our common stock has been, and may continue to be, highly volatile.

The market price of our common stock on the NASDAQ has been volatile in recent years. We may continue to experience significant volatility in the market price of our common stock. Numerous factors could have a significant effect on the price of our common stock, including:

announcements of fluctuations in our operating results or the operating results of one of our competitors;

market conditions in our customers' industries;

capital spending plans of our significant customers;

global and domestic energy prices;

announcements by us or one of our competitors of new or terminated customers or new, amended or terminated contracts;

announcements of acquisitions by us or one of our competitors;

changes in recommendations or earnings estimates by securities analysts; and

future sales of our common stock.

In addition, the stock market has experienced significant price and volume fluctuations in recent years, which have sometimes been unrelated or disproportionate to operating performance. Volatility in the market price of our common stock could cause shareholders to lose some or all of their investment in our common stock.

We are an “emerging growth company” and the reduced disclosure requirements applicable to “emerging growth companies” may make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act. For as long as we continue to be an “emerging growth company,” we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies. Among other things, we will not be required to (1) provide an auditor’s attestation report on management’s assessment of the effectiveness of our system of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act, (2) comply with any new rules that may be adopted by the PCAOB requiring mandatory audit firm rotation or a supplement to the auditor’s report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer, (3) comply with any new audit rules adopted by the PCAOB after April 5, 2012 unless the SEC determines otherwise, (4) comply with any new or revised financial accounting standards applicable to public companies until such standards are also applicable to private companies under Section 102(b) of the JOBS Act, (5) provide certain disclosure regarding executive compensation required of larger public companies, or (6) hold a nonbinding


advisory vote on executive compensation and obtain shareholder approval of any golden parachute payments not previously approved.

Accordingly, the information that we provide shareholders in this annual report and in our other filings with the SEC may be different than what is available with respect to other public companies. In particular, as we have elected to take advantage of the extended transition period for complying with new or revised accounting standards applicable to public companies, our financial statements may not be comparable to companies that comply with public company effective dates for such new or revised standards. We cannot predict if investors will find our common stock less attractive because we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile and adversely affected. In addition, as we are not required to have our auditors formally attest to and report on the effectiveness of our internal control over financial reporting, we cannot predict the outcome of testing in future periods. If, once we are no longer an “emerging growth company,” our independent registered public accounting firm cannot provide an unqualified attestation report on the effectiveness of our internal control over financial reporting, investor confidence and, in turn, the market price of our common stock could decline.

We will remain an “emerging growth company” until the earliest of (1) the last day of the first fiscal year in which our total annual gross revenues exceed $1.07 billion, (2) the date on which we are deemed to be a “large accelerated filer,” as defined in Rule 12b-2 under the Exchange Act or any successor statute, which would occur if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, (3) the date on which we have issued more than $1 billion in non-convertible debt during the preceding three-year period, and (4) the end of the fiscal year following the fifth anniversary of the date of the first sale of our common stock pursuant to an effective registration statement filed under the Securities Act, or July 6, 2021.

M III and Oaktree have significant ability to influence corporate decisions.

Oaktree and M III beneficially own approximately 48.0% and 9.5%, respectively, of our common stock as of December 31, 2018. These ownership percentages take into account both the vested founder shares and unvested founder shares.

As long as M III or Oaktree own or control a significant percentage of our outstanding voting power, they will have the ability to significantly influence all corporate actions requiring stockholder approval, including the election and removal of directors and the size of our Board, any amendment to our certificate of incorporation or bylaws, or the approval of any merger or other significant corporate transaction, including a sale of substantially all of our assets.

In addition, pursuant to the terms of the Investor Rights Agreement, each of Oaktree, on the one hand, and M III, on the other hand, will have consent rights over certain matters for so long as Oaktree or M III, respectively, directly or indirectly, beneficially own at least fifty percent (50%) of the Common Stock (including unvested founder shares, in the case of the M III) beneficially owned by the Selling Stockholders or the Sponsors, respectively, as of the closing of our business combination, including:

entering into, waiving, amending or otherwise modifying the terms of any transaction or agreement between the Company or any of its subsidiaries, on the one hand, and (a) the M III or their affiliates or any affiliate of the Company, on the other hand (in the case of Oaktree), other than the exercise of any rights under certain existing agreements (without giving effect to any subsequent amendments) or (b) certain Selling Stockholders, Oaktree or their affiliates (in the case of the M III), subject to certain exceptions, and other than the exercise of any rights under certain existing agreements (without giving effect to any subsequent amendments);

hiring or removing the Chief Executive Officer or any other executive officer of the Company or its subsidiaries; or

except as contemplated by the Investor Rights Agreement, increasing or decreasing the size of the Board.

M III and Oaktree will also have ongoing rights to nominate one or two directors, depending on the ownership interests of Oaktree or the M III, respectively, and, in the case of an increase in the size of the Board or an increase in their respective ownership percentages, additional directors proportional to their respective ownership percentages.

In addition, Oaktree’s consent will be required under the terms of the Certificate of Designation for the Company and its subsidiaries to take certain actions, including:

Creating, authorizing or issuing any stock that ranks senior to or on parity with the Series A Preferred Stock with


respect to payment of dividends or upon liquidation, any capital stock that votes as a single class with the holders of Series A Preferred Stock with respect to the consent rights granted pursuant to the Certificate of Designation, or any stock of any subsidiary of the Company (with certain exceptions);

Reclassifying or amending any capital stock if it would render such capital stock senior to or on parity with the Series A Preferred Stock;

Entering into any agreement with respect to or consummating any merger, consolidation or similar event pursuant to which the Company or its subsidiary would not be the surviving entity if as a result of which any capital stock of such surviving entity would rank senior to or on parity with the Series A Preferred Stock;

Incurring or guaranteeing debt if as a result the Company and its subsidiaries would have aggregate debt in excess of $5,000,000 other than pursuant to the replacement credit facility or any refinancing thereof;

Authorizing or consummating any change of control event or liquidation (as described in the Certificate of Designation); or

Modifying the Certificate of Designation or other organizational document of the Company in a manner that would reasonably be expected to be materially adverse to the holders of Series A Preferred Stock.

The interests of M III or Oaktree may not align with the interests of our other stockholders. M III and Oaktree are in the business of making investments in companies and may acquire and hold interests in businesses that compete directly or indirectly with us. M III or Oaktree may also pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us. Our current certificate and our proposed certificate of incorporation also provides that M III and Oaktree and their respective partners, principals, directors, officers, members, managers and/or employees, including any of the foregoing who serve as officers or directors of the post-combination company, do not have any fiduciary duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as the post-combination company or any of its subsidiaries.

Our quarterly operating results may fluctuate significantly and could fall below the expectations of securities analysts and investors due to seasonality and other factors, some of which are beyond our control, resulting in a decline in our stock price.

Our quarterly operating results may fluctuate significantly because of several factors, including:

labor availability and costs for hourly and management personnel;

profitability of our products and services, especially in new markets and due to seasonal fluctuations;

changes in interest rates;

impairment of long-lived assets;

macroeconomic conditions, both nationally and locally;

negative publicity relating to products and services we offer;

changes in consumer preferences and competitive conditions;

expansion to new markets; and

fluctuations in commodity prices.

Our articles of incorporation and certain provision of Delaware law contain anti-takeover provisions that could impair a takeover attempt.

As a Delaware corporation, anti-takeover provisions may impose an impediment to the ability of others to acquire control of us, even if a change of control would be of benefit to our stockholders. In addition, certain provisions of our


Articles of Incorporation and Bylaws also may impose an impediment or discourage others from a takeover.

These provisions include:

a staggered Board providing for three classes of directors, which limits the ability of a stockholder or group to gain control of our Board;

a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

a prohibition on stockholders calling a special meeting and the requirement that a special meeting of stockholders may only be called by (i) the chairman of our Board, (ii) our Chief Executive Officer, (iii) a majority of our Board, or (iv) directors designated by the Sponsors or Oaktree subject to certain conditions set forth in the Investor Rights Agreement; and

the requirement that changes or amendments to certain provisions of our certificate of incorporation or bylaws must be approved by holders of at least two-thirds of the Common Stock of the post-combination company and, in the case of our Bylaws, in some cases 80% of the Common Stock.

(2) The calculation of weighted average common shares outstanding during the periods preceding a reverse recapitalization generally requires the Company to use the capital structure of the entity deemed to be the acquirer for accounting purposes to


calculate EPS. However, as a limited liability company, IEA Services had no outstanding common shares prior to the Merger. Therefore, the weighted average common shares outstanding for all comparable prior periods preceding the Merger is based on the capital structure of the acquired company, as management believes that is the most useful measure.

Trends and Future Opportunities

Business Environment

We believe there are long-term growth opportunities across our industries, and we continue to have a positive long-term outlook. We believe that with our full-service operations, broad geographic reach, financial position and technical expertise, we are well positioned to mitigate the risks and challenges while continuing to capitalize on opportunities and trends in our industries.

Labor Shortage. We continue to address the longer-term need for additional labor resources in our markets, as our customers continue to seek additional specialized labor resources to address an aging workforce and longer-term labor availability issues, increasing pressure to reduce costs and improve reliability, and increasing duration and complexity of their capital programs. We believe these trends will continue, possibly to such time,a degree that demand for labor resources will outpace supply. Furthermore, the cyclical nature of the Renewable and, to a certain extent, parts of our Specialty Civil segment, can create shortages of qualified labor in those markets during periods of high demand. Our ability to capitalize on available opportunities is limited by our ability to employ, train and retain the necessary skilled personnel, and therefore we are taking proactive steps to develop our workforce, including through strategic relationships with universities, the military and unions and
28


the expansion and development of our training facility and postsecondary educational programs. Although we believe these initiatives will help address workforce needs, meeting our customers’ demand for labor resources could remain challenging.

Additionally, we believe that labor costs will increase given the recent escalated inflationary environment in the United States. Our labor costs are typically passed through in our contracts, and the portion of our workforce that is represented by labor unions typically operate under multi-year collective bargaining agreements, which provide some visibility into future labor costs. As a result, while we continue to monitor our labor markets, we do not currently believe this environment will present a material risk to our profitability and would expect to be able to adjust contract pricing with customers to the extent wages and other parties thereto,labor costs increase, whether due to renegotiation of collective bargaining agreements or market conditions.

Supply Chain Disruption. We are experiencing supply chain disruptions in our end markets related to the following issues;

Labor shortages at suppliers have increased delays of the production of certain materials, including but not limited to machinery, tools, copper, reinforced steel, solar panels and other items;
Shipping costs have increased significantly due to higher demand for products but fewer delivery options due to a reduction of truck drivers and rail cars;
Delayed sequencing in our projects related to the inability to determine specific delivery dates for key materials;
Cost increases for tax, tariffs and border controls for materials entering the U.S. from other countries; and
Bans on imports of certain goods from China, particularly of polysilicon covered by the Uyghur Forced Labor Prevention Act, which provided for, among other things, the Merger of IEA Services with and intois a wholly-owned subsidiary of M III. See Note 2. Merger, Acquisitions and Discontinued Operationssignificant input in the notesproduction of solar panels. These bans could result in project delays and increased costs to us or our customers.

We continue to monitor these supply chain disruptions and other logistical challenges, global trade relationships (e.g., tariffs, sourcing restrictions) and other general market and political conditions (e.g., inflation, Ukraine conflict) with respect to availability and costs of certain materials and equipment necessary for the performance of our business and for materials necessary for our customers’ projects. For example, in the renewable energy market are experiencing supply chain challenges, resulting in delays and shortages of, and increased costs for, materials necessary for the construction of certain renewable energy projects in the near term, including as a result of sourcing restrictions related to solar panels manufactured in China. While we believe many of our renewable energy customers may be able to manage near-term supply chain disruptions better than their smaller competitors, these challenges could delay our customers’ ongoing projects or impact their future project schedules, which in turn could impact the timing of our projects. While these delays are not anticipated to result in exposure to liquidated damages or commodity risks, such delays could cause our customers to cancel projects as higher than expected costs impact their project profitability projections which could impact our profitability and cash flow.

Regulatory Challenges. The regulatory environment creates both challenges and opportunities for our business, and in recent years heavy civil and rail construction have been impacted by regulatory and permitting delays in certain periods, particularly with respect to regulatory and environmental permitting processes continue to create uncertainty for projects and negatively impact customer spending, and delays have increased as the COVID-19 pandemic has impacted regulatory agency operations.

However, we believe that there are also several existing, pending or proposed legislative or regulatory actions that may alleviate certain regulatory and permitting issues and positively impact long-term demand, particularly in connection with infrastructure and renewable energy spending. For example, regulatory changes affecting siting and 30 right-of-way processes could potentially accelerate construction for transmission projects, and state and federal reliability standards are creating incentives for system investment and maintenance. Additionally, as described above, we consider renewable energy, including solar and wind generation facilities, to be an ongoing opportunity; however, policy and economic incentives designed to support and encourage such projects can create variability of project timing.

For further discussion of these risks see Item 1A. Risk Factors, Results of Operations and Forward-Looking Statements.

Renewables Segment

During 2021, results of the Renewables segment had the following significant operational trends:

Revenue increased by 27.9% to $1,461.1 million during the year ended December 31, 2021 as compared to $1,142.8 million for 2020.
29


Our consistent, safe and reliable performance with our customers on our wind projects has allowed us to capture further solar opportunities from those same customers in backlog for 2022 and beyond.

Renewable energy has experienced timing delays in regards to slower delivery times for solar panels and wind turbines. This affected the sequencing on some of our solar projects in 2021 and could impact future projects if the supply chain issues continue to grow.

We have maintained a heavy focus on construction of renewable power production capacity as renewable energy, particularly from wind and solar, has become widely accepted within the electric utility industry and has become a cost-effective solution for the creation of new generating capacity. We believe that this shift coupled with the below, will continue to drive opportunity in this segment over the long-term:

Renewable energy power generation has reached a level of scale and maturity that permits these technologies to now be cost-effective competitors to more traditional power generation technologies, including on an unsubsidized basis. The most significant changes have been related to increased turbine sizes and better battery storage methods.

Over 40 states and the District of Colombia have adopted renewable portfolio standards for clean energy.

On June 29, 2021, the IRS issued a notice which provides that projects that began construction in 2016-2019 have six years, and projects that began construction in 2020 have five years, from the date construction began to be placed-in-service to qualify for the PTC or ITC that was in effect when construction began. This new rule effectively extends the amount of time that many projects will be eligible for PTC to 2025.

As a result, wind and solar power are among the leading sources of new power generation capacity in the U.S., and we do not anticipate this trend to change in the near future as we are continuing to see growth through new awards in our backlog:

We believe that through the Mergerour business relationships with customers in these sectors are excellent and the acquisitions abovestrong reputation that we have built has provided us with the right foundation to continue to grow our revenue base. The drivers to further growing this segment our as follows:

The FMI 2022 Overview Report published in the first quarter of 2022 projects that nonresidential construction put in place for the United States will be over $500 billion per year from 2022 to 2025.

Infrastructure Investment and Jobs Act will provide $1.2 trillion of federal spending for infrastructure and other investments, including $550 billion of new spending over the next five years. This bill includes provision for spending in the following areas:
Environmental remediation $21.0 billion
Roads & Bridges $110.0 billion
Passenger & Freight Rail $66.0 billion

U.S. Environmental Protection Agency ("EPA") has continued to take action on controlling and cleaning up the contamination of coal ash disposal. In January 2022, the EPA alluded to future additional regulations, finalizing a federal permitting program for how companies should safely dispose of coal ash, and establishing regulations for legacy coal ash surface impoundment. These additional regulations could signal a slower market as our customers develop strategies on how to comply with any new guidance put forth by the EPA.

Additionally, there is significant overlap in labor, skills and equipment needs between our Renewables segment and our Specialty Civil segment, which we expect will continue to provide us with operating efficiencies as we continue to expand this sector. The Company continues to cross leverage these two segments and continues to see future growth through new awards in our backlog:

While we actively monitor economic, industry and market factors that could affect our business, we cannot predict the effect that changes in such factors may have on our future results of operations liquidity and cash flows, and we maycan be unable to fully mitigate, or benefit from, such changes.

Impact of Seasonality and Cyclical Nature of Business

Our revenue and results of operations are subject to seasonal and other variations. These variations are influenced by weather, customer spending patterns, bidding seasons, fiscal year-ends, project schedulesa variety of factors in any given period, including those described in Item 1A. Risk Factors and timing, in particular, for large non-recurring projectsResults of Operations and holidays.Forward-Looking Statements, and those factors have caused fluctuations in our results in the past and are expected to cause fluctuations in our results in the future. Additional information with respect to certain of those factors is provided below.

Seasonality. Typically, our revenue isrevenues are lowest in the first quarter of the year because cold, snowy or wet conditions experiencedcan create challenging working environments that are more costly for our customers or cause delays on projects. In addition, infrastructure projects often do not begin in a meaningful way until our customers finalize their capital budgets, which typically occurs during the northern climatesfirst quarter. Second quarter revenues are not conducive to efficient or safe construction practices. Revenue in the second quarter is typically higher than those in the first quarter, as some projects begin, but continued cold and wet weather and effects from thawing ground conditions can often impact secondproductivity. Third quarter productivity. The third and fourth quartersrevenues are typically the most productive quartershighest of the year, as a greater number of projects are underway and operating conditions, including weather, isare normally more accommodating to construction projects. Inaccommodating. Generally, revenues during the fourth quarter are lower than the third quarter but higher than the second quarter, as many projects tend to beare completed byand customers seekingoften seek to spend their capital budgets before the end of the year which generally has a positive impact on our revenue. Nevertheless,end. However, the holiday season and inclement weather can sometimes cause delays which can reduceduring the fourth quarter, reducing revenues and increasing costs.
Our revenue and increase costs on affected projects. Anyresults of operations for our Specialty Civil segment are also effected by seasonality but to a lesser extent as these projects are more geographically diverse and located in less severe weather areas. While the first and second quarter revenues are typically lower than the third and fourth quarter, the geographical diversity has allowed this segment to be less seasonal over the course of the year.

Weather and Natural Disasters. The results of our business in a given period can be impacted by adverse weather conditions, severe weather events or natural disasters, which include, among other things, heavy or prolonged snowfall or rainfall, hurricanes, tropical storms, tornadoes, floods, blizzards, extreme temperatures, wildfires, pandemics and earthquakes, and which may be positivelyexacerbated by climate change. These conditions and events can negatively impact our financial results due to the termination, deferral or negatively affected by adverse or unusual weather patterns, including from excessive rainfall, warm winter weather or natural catastrophes such as hurricanes or other severe weather, making it difficultdelay of projects, reduced productivity and exposure to predict quarterly revenue and margin variations.significant liabilities.


Our industry is also highly cyclical.
32


Cyclical demand. Fluctuations in end-user demand within the industries we serve, or in the supply of services within those industries, can impact demand for our services. As a result, our business may be adversely affected by industry declines or by delays in new projects. Variations in project schedules or unanticipated changes in project schedules, in particular, in connection with large construction and installation projects, can create fluctuations in revenue, which may adversely affect us in a given period. In addition, revenue from master service agreements, while generally predictable, can be subject to volatility. The financial condition of our customers and their access to capital, variations in project margins, regional, national and global economic, political and market conditions, regulatory or environmental influences, and acquisitions, dispositions or strategic investments can also materially affect quarterly results. Accordingly, our operating results in any particular period may not be indicative of the results that can be expected for any other period.


Our 2018 results reflect the effect of multiple severe weather events on the Company's wind business that began late in the third quarter and continued into the fourth quarter. These weather conditions had a significant impact on the construction of six wind projects across South Texas, Iowa, and Michigan, resulting in additional labor, equipment and material costs as well as change orders. IEA is aggressively pursuing the collection of all amounts it is contractually owed due to weather-related delays, including collections on change orders resulting from force majeure provisions of certain customer contracts, which generally compensate for the actual costs of weather-related delays. See Results of Operations for further discussion of weather impact.



Understanding our Operating Results

“Emerging Growth Company” Status

IEA qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). For as long as a company is deemed to be an “emerging growth company,” it may take advantage of specified reduced reporting and other regulatory requirements that are generally unavailable to other public companies. The JOBS Act also provides that an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of this extended transition period. Our financial statements may therefore not be comparable to those of companies that have adopted such new or revised accounting standards. See Note 1. Business, Basis of Presentation and Significant Accounting Policies to our consolidated financial statements for more information on “emerging growth company” reduced reporting requirements and when we would cease to be an “emerging growth company.” We continue to monitor our status as an “emerging growth company” and are currently preparing, and expect to be ready to comply with, the additional reporting and regulatory requirements that will be applicable to us when we cease to qualify as an “emerging growth company.”

Revenue

We provide engineering, building, installation, maintenance and upgrade services to our customers. We derive revenue from projects performed under fixed price contracts and other service agreements for specific projects or jobs requiring the construction and installation of an entire infrastructure system or specified units within an entire infrastructure system. We recognize a significant portion of our revenue based on the percentage-of-completion method. See Revenue Recognition for Percentage-of-Completion Projects within Critical Accounting Policies and Estimates below.

Cost of Revenue

Cost of revenue consists principally of: salaries, wages and employee benefits; subcontracted services; equipment rentals and repairs; fuel and other equipment expenses, including allocated depreciation and amortization expense; material costs, parts and supplies; insurance; and facilities expenses. Project profit is calculated by subtracting a project’s cost of revenue, including project-related depreciation, from project revenue. Project profitability and corresponding project margins will be reduced if actual costs to complete a project exceed our estimates on fixed price and installation/construction service agreements. Estimated losses on contracts are recognized immediately when estimated costs to complete a project exceed the remaining revenue to be received over the remainder of the contract. Various factors, some controllable and some not, can impact our margins on a quarterly or annual basis, including:
Seasonality and Geographical Factors. Seasonal patterns can have a significant impact on project margins. Generally, business is slower at the beginning of the year. Adverse or favorable weather conditions can impact project margins in a given period. For example, extended periods of rain or snowfall can negatively impact revenue and project margins as a result of reduced productivity from projects being delayed or temporarily halted. Conversely, in periods when weather remains dry and temperatures are accommodating, more work can be done, sometimes with less cost, which can favorably impact project margins. In addition, the mix of business conducted in different geographic areas can affect project margins due to the particular characteristics associated with the physical locations where the work is being performed, such as mountainous or rocky terrain versus open terrain. Site conditions, including unforeseen underground conditions, can also impact project margins.
Revenue Mix.mix. The mix of revenues derived from the industries we serve andbased on the types of services we provide within an industryin a given period will impact margins, as certain industries and services provide higher-margin opportunities. Revenue derived from projects billed on a fixed-price basis totaled 98.9% for the year ended December 31, 2021. Revenue and related costs for construction contracts billed on a time and materials basis are recognized as the services are rendered. Revenue derived from projects billed on a time and materials basis totaled 1.1% of consolidated revenue for the year ended December 31, 2021.

Size, scope and complexity of projects. Larger or more complex projects with design or construction complexities; more difficult terrain requirements; or longer distance requirements typically yield opportunities for higher margin opportunities. Additionally,margins as we assume a greater degree of performance risk and there is greater utilization of our resources for longer construction timeframes. Furthermore, smaller or less complex projects typically have a greater number of companies competing for them, and competitors at times may more aggressively pursue available work. A greater percentage of smaller scale or less complex work also could negatively impact margins due to the inefficiency of transitioning between a larger number of smaller projects versus continuous production on fewer larger projects. Also, at times we may choose to maintain a portion of our workforce and equipment in an underutilized capacity to ensure we are strategically positioned to deliver on larger projects when they move forward.

Project variability and performance. Margins for a single project may fluctuate period to period due to changes in the volume or type of work performed, the pricing structure under the project contract or job productivity. Additionally, our customers’ spending patterns in anyproductivity and performance on a project can vary period to period based on a number of factors, including unexpected project difficulties or site conditions; project location, including locations with challenging operating conditions; whether the industries we serve can causework is on an imbalance in supplyopen or encumbered right of way; inclement weather or severe weather events; environmental restrictions or regulatory delays; protests, other political activity or legal challenges related to a project; and demandthe performance of third parties.

Subcontract work and provision of materials. Work that is subcontracted to other service providers generally yields lower margins, and therefore affect margins and mix of revenues by industry served.
Performance Risk. Overall project margins may fluctuate due toan increase in subcontract work volume, project pricing and job productivity. Job productivity can be impacted by quality of the work crew and equipment, availability of skilled labor, environmental or regulatory factors, customer decisions and crew productivity. Crew productivity can be influenced by weather conditions and job terrain, such as whether project work is in a right of way that is open or one that is obstructed (either by physical obstructions or legal encumbrances).
Subcontracted Resources. Our use of subcontracted resources in a given period can decrease margins. Our customers are usually responsible for supplying the materials for their projects; however, under some contracts we agree to procure all or part of the required materials. Margins may be lower on projects where we furnish a significant amount of materials, including projects where we provide engineering, procurement and construction ("EPC") services, as our markup on materials is dependent upon activity levels andgenerally lower than our markup on labor costs. Furthermore, fluctuations in the amount and locationprice of existing in-house resources and capacity. Project margins on subcontracted work can vary from project margins on self-perform work. Asmaterials we procure, including as a result of changes in the mix of subcontracted resources versus self-perform work canU.S. or global trade relationships or other economic or political conditions, may impact our overall project margins.

Interest Expense, Net

Interest expense, net consistsnet. Interest expense decreased by 27.5%, or $17.0 million, during the year ended December 31, 2021 as compared to 2020. This decrease was driven by the redemption of contractual interest expense on outstanding debt obligations, amortization of deferred financing costs and other interest expense, includingSeries B Preferred Stock, offset by the interest expense related to financing arrangements, with all such expenses netour Senior Unsecured Notes and prior term loan.

Provision for income taxes. Income tax expense decreased by 11.0%, or $1.4 million, during the year ended December 31, 2021, compared to 2020. The effective tax rates for the years ended December 31, 2021 and 2020were (15.4)% and 94.5%, respectively. The difference in effective tax rate in 2021 was primarily attributable to a significant permanent adjustment of $87.7 million related to the redemption of the Series B Preferred Stock which is not deductible for federal and state income taxes.

Segment Results

We operated our business as two reportable segments: the Renewables segment and the Specialty Civil segment. Each of our reportable segments is comprised of similar business units that specialize in services unique to the respective markets that each segment serves. The classification of revenue and gross profit for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses, associatedwere made based on segment revenue.

The following table sets forth segment revenues and gross profit for the years indicated, as well as the dollar and percentage change from the prior year:

Renewables Segment Results

Revenue. Renewables revenue was $1,461.1 million for the year ended December 31, 2021 as compared to $1,142.8 million for 2020, an increase of 27.9%, or $318.3 million. The increase in revenue was primarily due to:

The average revenue of the 22 wind projects of greater than $5.0 million of revenue was $49.2 million in 2021 compared to $40.7 million related to 25 projects greater than $5.0 million of revenue during 2020; and
Solar revenue increased $204.6 million for the year ended December 31, 2021 when compared to 2020;

35


Gross profit. Renewablesgross profit was $141.7 million for the year ended December 31, 2021 as compared to $126.9 million for 2020, an increase of 11.7%, or $14.8 million. As a percentage of revenue, gross profit was 9.7% in 2021, as compared to 11.1% in 2020. The decrease in percentage was primarily due to challenges related to supply chain disruption in our solar business that caused inefficiencies in project sequencing on a few large projects.

Specialty Civil Segment Results

Revenue. Specialty Civil revenue was $617.3 million for the year ended December 31, 2021 as compared to $610.1 million for 2020, an increase of 1.2%, or $7.2 million. The increase in revenue was primarily due to:

Increases in our environmental remediation market due to more projects in 2021 compared to 2020; and
Decreases in the rail and heavy civil markets, as rail markets continue to experience a decrease in revenue primarily due to delay in project starts for railroads and lower budgets decreasing bidding opportunities.

Gross profit. Specialty Civil gross profit was $64.4 million for the year ended December 31, 2021 as compared to $61.8 million for 2020, an increase of 4.2%, or $2.6 million. As a percentage of revenue, gross profit was 10.4% in 2021, as compared to 10.1% in 2020. The increase in percentage was primarily due to growth in the environmental remediation market and the project mix in 2021 compared to 2020.

Liquidity and Capital Resources

    Liquidity is provided by available cash balances, cash generated from operations, availability under our credit facility and access to capital markets. We have a committed line of credit totaling $150.0 million, which may be used for revolving loans, letters of credit and/or general purposes. We believe the cash generated from operations, along with our Canadianunused credit capacity of $118.9 million and available cash balances as of December 31, 2021, will be sufficient to fund any working capital needs and plans for cash for the next 12 months and beyond. For information on our material cash requirements from known contractual and other obligations, please refer to “Contractual Obligations” below.

To the extent that cash from operations and borrowings under our revolving credit facility are not sufficient to meet our liquidity needs in the next twelve months, we expect to access other sources of liquidity through alternative sources such as issuance of debt and equity securities, expansions of our credit facility or other sources. There can be no assurance that were completely abandoned.any such sources will be available or if they are available that we can obtain capital from such sources on commercially reasonable terms.

Working Capital

    We effectively completed all significantrequire working capital to support seasonal variations in our business, primarily due to the effect of weather conditions on external construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated spending to support related customer demand. Our business is typically slower in the first quarter of each calendar year. Working capital needs are generally lower during the spring when projects are awarded and we receive down payments from customers. Conversely, working capital needs generally increase during the summer or fall months due to increased demand for our services when favorable weather conditions exist in many of the regions in which we operate. Working capital needs are typically lower and working capital is converted to cash during the winter months. These seasonal trends, however, can be offset by changes in the timing of projects, which can be affected by project delays or accelerations and/or other factors that may affect customer spending.

Sources and Uses of Cash

    Sources and uses of cash are summarized below for the periods indicated:
Year Ended December 31,
(in thousands)20212020
Net cash (used in) provided by operating activities$(10,850)$57,745 
Net cash used in investing activities(23,548)(3,113)
Net cash used in financing activities(5,616)(37,850)

Operating Activities. Net cash used in operating activities for the year ended December 31, 2021 was $10.9 million as compared to net cash provided by operating activities of $57.7 million for 2020. The increase in net cash used in operating
36


activities reflects the timing of receipts from customers and payments to vendors in the ordinary course of business. Based on the timing of completion on our renewable projects in Canadathe current year compared to the prior year we had higher billings of accounts receivable and reducedcontract assets, partially offset by lower payments on payables and accrued liabilities.

Investing Activities. Net cash used in investing activities for the year ended December 31, 2021 was $23.5 million as compared $3.1 million for 2020. The increase in net cash used by investing activities was primarily attributable to an increase in purchases of property, plant and equipment.

Financing Activities. Net cash used in financing activities for the year ended December 31, 2021 was $5.6 million as compared to net cash used in financing activities of $37.9 million for 2020. The decrease in net cash used by financing activities was primarily attributable to proceeds from the debt and equity offerings, offset by the extinguishment of the term loan and Series B Preferred Stock.

Capital Expenditures

    For the year ended December 31, 2021, we acquired equipment for $26.6 million under finance leases and paid an additional $30.2 million in cash purchases. We estimate that we will spend approximately two percent of revenue for capital expenditures in 2022. Actual capital expenditures may increase or redeployeddecrease in the future depending upon business activity levels, as well as ongoing assessments of equipment lease versus buy decisions based on short and long-term equipment requirements.

Debt

Senior Unsecured Notes

On August 17, 2021, IEA Energy Services LLC, a wholly owned subsidiary of the Company (“Services”), issued $300.0 million aggregate principal amount of its 6.625% senior unsecured notes due 2029 (the “Senior Unsecured Notes”), in a private placement. Interest is payable on the Senior Unsecured Notes on each February 15 and August 15, commencing on February 15, 2022. The Senior Unsecured Notes will mature on August 15, 2029. The Senior Unsecured Notes are guaranteed on a senior unsecured basis by the Company and certain of its domestic wholly-owned subsidiaries (the “Guarantors”).

On or after August 15, 2024, the Senior Unsecured Notes are subject to redemption at any time and from time to time at the option of Services, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if redeemed during the twelve-month period beginning on August 15 of the years indicated below:

YearPercentage
2024103.3 %
2025101.7 %
2026 and thereafter100.0 %

Prior to August 15, 2024, Services may also redeem some or all of the Senior Unsecured Notes at the principal amount of the Senior Unsecured Notes, plus a “make-whole premium,” together with accrued and unpaid interest. In addition, at any time prior to August 15, 2024, Services may redeem up to 40.0% of the original principal amount of the Senior Unsecured Notes with the proceeds of certain equity offerings at a redemption price of 106.63% of the principal amount of the Senior Unsecured Notes, together with accrued and unpaid interest.

In connection with the issuance of the Senior Unsecured Notes, Services entered into an indenture (the “Indenture”) with the Guarantors and Wilmington Trust, National Association, as trustee, providing for the issuance of the Senior Unsecured Notes. The terms of the Indenture provides for, among other things, negative covenants that under certain circumstances would limit Services’ ability to incur additional indebtedness; pay dividends or make other restricted payments; make loans and investments; incur liens; sell assets; enter into affiliate transactions; enter into certain sale and leaseback transactions; enter into agreements restricting Services' subsidiaries' ability to pay dividends; and merge, consolidate or amalgamate or sell all or substantially all of its property, subject to certain thresholds and exceptions. The Indenture provides for customary events of default that include (subject in certain cases to customary grace and cure periods), among others, nonpayment of principal or interest; breach of other covenants or agreements in the Indenture; failure to pay certain other indebtedness; failure to pay certain final judgments; failure of certain guarantees to be enforceable; and certain events of bankruptcy or insolvency.

Credit Agreement

On August 17, 2021, Services, as the borrower, and certain guarantors (including the Company), entered into a Credit Agreement (the “Credit Agreement”) with a syndicate of lenders and CIBC Bank USA in its capacities as the Administrative and Collateral Agent for the lenders. The Credit Agreement provides for a $150.0 million senior secured revolving credit facility. The Credit Agreement is guaranteed by the Company and certain subsidiaries of the Company (the “Credit Agreement Guarantors” and together with Services, the “Loan Parties”) and is secured by a security interest in substantially all of the Loan Parties’ personal property and assets. Services has the ability to increase available borrowing under the credit facility by an additional amount up to $50.0 million subject to certain conditions.

Services may voluntarily repay and reborrow outstanding loans under the credit facility at any time subject to usual and customary breakage costs for borrowings bearing interest based on LIBOR and minimum amount requirements set forth in the Credit Agreement. The credit facility includes $100.0 million in borrowing capacity for the issuance of letters of credit. The credit facility is not subject to amortization and matures with all commitments terminating on August 17, 2026.

Interest rates on the credit facility are based upon (1) an index rate that is established at the highest of the prime rate or the sum of the federal funds rate plus 0.50%, or (2) at Services’ election, a LIBOR rate, plus in either case, an applicable interest rate margin. The applicable interest rate margins are adjusted on a quarterly basis based upon Services’ first lien net leverage within the range of 1.00% to 2.50% for index rate loans and 2.00% and 3.50% for LIBOR loans. Borrowings under the credit facility shall initially bear interest at a rate per annum equal to LIBOR plus 2.50%. In anticipation of LIBOR's phase out, our Canadian resources, facilitiesCredit Agreement includes a well-documented transition mechanism for selecting a benchmark replacement rate for LIBOR. In addition to paying interest on outstanding principal under the credit facility, Services is required to pay a commitment fee to the lenders under the credit facility for unused commitments. The commitment fee rate ranges from 0.30% to 0.45% per annum depending on Services’ First Lien Net Leverage Ratio (as defined in the Credit Agreement).

The credit facility requires Services to comply with a quarterly maximum consolidated First Lien Net Leverage Ratio test and minimum Fixed Charge Coverage ratio as follows:

Fixed Charge Coverage Ratio - The Loan Parties shall not permit the Fixed Charge Coverage Ratio (as defined in the Credit Agreement) as of the last day of any four consecutive fiscal quarter period ending on the last day of a fiscal quarter to be less than 1.20:1.00.

First Lien Net Leverage Ratio – The Loan Parties will not permit the First Lien Net Leverage Ratio (as defined in the Credit Agreement) as of the last day of any four consecutive fiscal quarter period ending on the last day of a fiscal quarter to exceed 1.75:1.00.

In addition, the Credit Agreement contains a number of covenants that, among other things and subject to certain exceptions, limit Services’ ability and the ability of its restricted subsidiaries including the Company to incur indebtedness or guarantee debt; incur liens; make investments, loans and acquisitions; merge, liquidate or dissolve; sell assets, including capital stock of subsidiaries; pay dividends on its capital stock or redeem, repurchase or retire its capital stock; amend, prepay, redeem or purchase subordinated debt; and engage in transactions with affiliates.

The Credit Agreement contains certain customary representations and warranties, affirmative covenants and events of default (including, among others, an event of default upon a change of control). If an event of default occurs, the lenders under the credit facility are entitled to take various actions, including the acceleration of amounts due under the credit facility and all actions permitted to be taken by a secured creditor.

Third A&R Credit Agreement and Term Loan

Prior to entering into the Credit Agreement, we were party to that certain Third A&R Credit Agreement, dated May 15, 2019, as amended (the “Third A&R Credit Agreement”), which governed the terms of our term loan (the “Term Loan”) and provided for revolving credit commitments of up to $75.0 million, upon the terms and subject to the satisfaction of the conditions set forth in the Third A&R Credit Agreement. The Term Loan was repaid in full and the Third A&R Credit Agreement has been terminated.

Series A Preferred Stock

On July 28, 2021, the Company entered into a Transaction Agreement (the “Transaction Agreement”) with Ares Special Situations Fund IV, L.P. (“ASSF”) and ASOF Holdings I, L.P. (“ASOF” and, together with ASSF, the “Ares Parties”). The Transaction Agreement resulted in, among other things: The Ares Parties converting all of their Series A Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”) (consisting of all of our issued and outstanding shares of Series A Preferred Stock), into 2,132,273 shares of Common Stock.

Series B Preferred Stock

In 2019, the Company entered into three equity purchase agreements and issued Series B Preferred Stock. The Series B Preferred Stock was a mandatorily redeemable financial instrument under ASC Topic 480 and had been recorded as a liability using the effective interest rate method for each tranche. The mandatory redemption date for all tranches of the Series B Preferred Stock was February 15, 2025.

On August 17, 2021, the Company redeemed all of the shares of Series B Preferred Stock at the Optional Redemption Price per share. The Optional Redemption Price was a price per share of Series B Preferred Stock in cash equal to $1,500, plus all accrued and unpaid dividends thereon since the immediately preceding dividend date calculated through the day prior to such redemption, minus the amount of any Series B preferred cash dividends actually paid. See the table in Note 7. Debt and Series B Preferred Stock for further discussion of proceeds and the loss on extinguishment.

Deferred Taxes - COVID-19

The CARES Act was enacted on March 27, 2020, in response to the COVID-19 emergency. The CARES Act includes many measures to assist companies, including temporary changes to income and non-income-based tax laws. Some of the key income tax-related provisions of the CARES Act include:

Eliminating the 80% of taxable income limitation by allowing corporate entities to fully utilize net operating losses (“NOLs”) to offset taxable income in 2018, 2019 or 2020.

Allowing NOLs originating in 2018, 2019 or 2020 to be carried back five years.

Increasing the net interest expense deduction limit to 50% of adjusted taxable income from 30% for tax years beginning 1 January 2019 and 2020.

Allowing taxpayers with alternative minimum tax (“AMT”) credits to claim a refund in 2020 for the entire amount of the credit instead of recovering the credit through refunds over a period of years, as originally enacted by the Tax Cuts and Jobs Act (“TCJA”).

Payroll tax deferral.

The Company made use of the payroll deferral provision to defer the 6.2% social security tax, or approximately $13.6 million, through December 31, 2020. This amount was paid at 50% on December 31, 2021. The remaining 50% is required to be paid on December 31, 2022.

(4)We lease real estate, vehicles, office equipment and certain construction equipment from unrelated parties under non-cancelable leases. Lease terms range from month-to-month to terms expiring through 2039.

Off-Balance Sheet Arrangements

    As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business. Our significant off-balance sheet transactions include liabilities associated with letter of credit obligations, surety and performance and payment bonds entered into in the normal course of business, liabilities associated with deferred compensation plans and liabilities associated with certain indemnification and guarantee arrangements.

Letters of Credit and Surety Bonds

    In the ordinary course of business, we may be required to post letters of credit and surety bonds to customers in support of performance under certain contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit or surety bond commits the issuer to pay specified amounts to the holder of the letter of credit or surety bond under certain conditions. If the letter of credit or surety bond issuer were required to pay any amount to a holder, we would be required to reimburse the issuer, which, depending upon the circumstances, could result in a charge to earnings. As of December 31, 2021 and 2020, we were contingently liable under letters of credit issued under our respective revolving lines of credit in the amount of $31.1 million and $7.8 million, respectively, related to projects and insurance. In addition, as of July 2016.December 31, 2021 and 2020, we had outstanding surety bonds on projects with nominal amounts of $3.3 billion and $2.8 billion, respectively. The remaining approximate exposure related to these surety bonds amounted to approximately $353.5 million and $293.1 million, respectively. We anticipate that our current bonding capacity will be sufficient for the next twelve months based on current backlog and available capacity.


See Note 8. Commitments and Contingencies to our consolidated financial statements for further discussion pertaining to certain of our off-balance sheet arrangements.

Critical Accounting Policies and Estimates


This management’s discussion and analysis of our financial condition and results of operations is based upon IEA’s consolidated financial statements included in Item 8, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires the use of estimates and assumptions that affect the amounts reported in our consolidated financial statements and the accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis of making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Given that management estimates, by their nature, involve judgments regarding future uncertainties, actual results may differ from these estimates if conditions change or if certain key assumptions used in making these estimates ultimately prove to be inaccurate. For discussion of all of our significant accounting policies, see Note 1. Business, Basis of Presentation and Significant Accounting Policies to our consolidated financial statements.

We believe that the accounting policies describeddiscussed below are the most critical in the preparation of our consolidated financial statements as they are important to the portrayal of our financial condition and require significant or complex judgment and estimates on the part of management.


Revenue Recognition for Percentage-of-Completion Projects


    The Company adopted the requirements of Accounting Standards Update (“ASU”) 2014-09, Revenue from fixed-priceContracts with Customers, which is also referred to as Accounting Standards Codification (“ASC”) Topic 606, under the modified retrospective transition approach effective January 1, 2019, with application to all existing contracts providesthat were not substantially completed as of January 1, 2019.

Contracts
    The Company derives revenue primarily from construction projects performed under contracts for aspecific projects requiring the construction and installation of an entire infrastructure system or specified units within an infrastructure system. Contracts contain multiple pricing options, such as fixed amount ofprice, time and materials, or unit price. Generally, renewable energy projects are performed for private customers while Specialty Civil projects are performed for various governmental entities.
    Construction contract revenue for the entire project, subject to certain additions for changed scope or specifications. We recognize revenue from these contractsis recognized over time using the percentage-of-completion method. Under this method,cost-to-cost measure of progress for fixed price contracts. The cost-to-cost measure of progress best depicts the percentagecontinuous transfer of revenue to be recognized for a given project is measured by the percentagecontrol of costs incurred to date on the contractgoods or services to the total estimatedcustomer. The contractual terms provide that the customer compensates the Company for services rendered.
Contract costs forinclude all direct materials, labor and subcontracted costs, as well as indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and the contract.

costs of capital equipment. The cost estimation and review process for recognizing revenue recognizedover time under the percentage-of-completioncost-to-cost method is based on the professional knowledge and experience of ourthe Company’s project managers, engineers and financial professionals. Our managementManagement reviews the estimates of total contract revenuetransaction price and total project costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of expected settlements of disputes related to contract price adjustmentsvariable consideration are factors that influence estimates of the total contract value andtransaction price, total costs to complete those contracts and therefore, our profit recognition. Changes in these factors maycould result in revisions to revenue and costs and income, and their effects are recognizedof revenue in the period in which the revisions are determined on a prospective basis, which could materially affect ourthe Company’s consolidated results of operations in the period in which such changes are recognized.for that period. Provisions for losses on uncompleted contracts are maderecorded in the period in which such losses are determineddetermined.
Performance Obligations
    A performance obligation is a contractual promise to be probabletransfer a distinct good or service to the customer and is the amount can be reasonably estimated.unit of account under Topic 606. The substantialtransaction price of a contract is allocated to distinct performance obligations and recognized as revenue when or as the performance obligations are satisfied. The Company’s contracts often require significant integrated services and, even when delivering multiple distinct services, are generally accounted for as a single performance obligation. Contract amendments and change orders are generally not distinct from the existing contract due to the significant integrated service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. With the exception of certain Specialty Civil service contracts, the majority of fixed price contractsthe Company’s performance obligations are generally completed within one year.

    When more than one contract is entered into with a customer on or close to the same date, the Company evaluates whether those contracts should be combined and accounted for as a single contract as well as whether those contracts should be accounted for as more than one performance obligation. This evaluation requires significant judgment and is based on the facts and circumstances of the various contracts, which could change the amount of revenue and profit recognition in a given period depending upon the outcome of the evaluation.
For an approved    Remaining performance obligations represent the amount of unearned transaction prices for fixed price contracts and open purchase orders for which work is wholly or partially unperformed. As of December 31, 2021, the amount of the Company’s remaining performance obligations was $2,002.5 million. The Company expects to recognize approximately 81.8% of its remaining performance obligations as revenue in 2022, with the remainder recognized primarily in 2023. Revenue recognized from performance obligations satisfied in previous periods was $2.0 million and $(10.0) million for the years ended December 31, 2021 and 2020, respectively.
Variable Consideration
    Transaction pricing for the Company’s contracts may include variable consideration, such as unapproved change orderorders, claims, incentives and liquidated damages. Management estimates variable consideration for a performance obligation

utilizing estimation methods that best predict the amount of consideration to which canthe Company will be reliablyentitled. Variable consideration is included in the estimated astransaction price to price, the anticipated revenues and costsextent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Management’s estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based on past practices with the customer, specific discussions, correspondence or preliminary negotiations with the customer, legal evaluations and all other relevant information that is reasonably available. The effect of a change orderin variable consideration on the transaction price of a performance obligation is typically recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders, claims and liquidated damages reflected in transaction price are addednot resolved in the Company’s favor, or to the total contract valueextent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.

    As of December 31, 2021 and total estimated costs of2020, the project, respectively. When costs are incurred for a) anCompany included approximately $94.5 million and $52.6 million, respectively, on unapproved change order which is probableorders and/or claims in the transaction price for certain contracts that were in the process of being resolved in the normal course of business, including through negotiation, arbitration and other proceedings. These transaction price adjustments are included within Contract Assets or Contract Liabilities as appropriate. The Company actively engages with its customers to complete the final approval process, and generally expects these processes to be approvedcompleted within one year. Amounts ultimately realized upon final acceptance by customers could be higher or b) an approved change orderlower than such estimated amounts.



Goodwill
which cannot be reliably estimated as to
    Goodwill represents the excess purchase price the total anticipated costs of the change order are added to both the total contract value and total estimated costs for the project. Once a change order becomes approved and reliably estimable, any margin related to the change order is added to the total contract value of the project.

Business Combinations

We account for our business combinations by recognizing and measuring in the financial statements the identifiable assets acquired, the liabilities assumed and any non-controlling interests (if applicable) in the acquiree at the acquisition date. The purchase is accounted for using the acquisition method, and the fair value of purchase consideration is allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair values. The excess, if any, of the fair value of the purchase considerationpaid over the fair value of the identifiable net assets is recorded as goodwill. Conversely, the excess, if any, of the net fair values of the identifiable net assets over the fair value of the purchase consideration is recorded as a gain. The fair values of net assets acquired are calculated using expected cash flowsintangible and industry-standard valuation techniques and these valuations require management to make significant estimates and assumptions. These estimates and assumptions are inherently uncertain and, as a result, actual results may materially differ from estimates. Significant estimates include, but are not limited to, future expected cash flows, useful lives and discount rates.

Due to the time required to gather and analyze the necessary data for each acquisition, U.S. GAAP provides a “measurement period” of up to one year in which to finalize these fair value determinations. During the measurement period, preliminary fair value estimates may be revised if new information is obtained about the facts and circumstances existing as of the date of acquisition, or based on the final net assets and working capital of the acquired business, as prescribed in the applicable purchase agreement. Such adjustments may result in the recognition, or adjust the fair values, of acquisition-related assets and liabilities and/or consideration paid, and are referred to as “measurement period” adjustments. For the year ended December 31, 2018, measurement period adjustments related to an increase to goodwill of $10.2 million and further adjustments discussed in Note 2. Merger, Acquisitions and Discontinued Operations included in Item 8.

Goodwill

We have goodwill that has been recorded in connection with our acquisitions of businesses.tangible assets. Goodwill is testedassessed annually for impairment at least annuallyon October 1st and tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. Under applicable guidance,The Company may assess its goodwill for impairment initially using a qualitative approach to determine whether conditions exist to indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value. If management concludes, based on its assessment of relevant events, facts and circumstances, that it is more likely than not that a reporting unit’s carrying value is greater than its fair value, then a quantitative analysis will be performed to determine if there is any impairment charges are requiredimpairment.

The quantitative assessment for goodwill requires us to estimate the fair value of each reporting unit carrying goodwill using a weighted combination of the income and market approaches. The income approach uses a discounted cash flow model, which involves significant estimates and assumptions including preparation of revenue and profitability forecasts, selection of a discount rate and selection of a long-term growth rate. The market approach uses an analysis of stock prices and enterprise values of a set of guideline public companies to arrive at a market multiple that is used to estimate fair value. If the fair value of the respective reporting unit exceeds its carrying amount, goodwill is not considered to be recorded as operating expenses. Forimpaired. If the years ended December 31, 2018, 2017 and 2016, wecarrying amount of a reporting unit exceeds its fair value, the Company would record an impairment charge equal to the difference, not to exceed the carrying amount of goodwill.

Management performed a qualitative assessment for ourthe goodwill recorded in its Renewables and Specialty Civil reporting units by examining relevant events and circumstances that could have an effect on its fair value, such as macroeconomic conditions, industry and market conditions, entity-specific events, financial performance and other relevant factors or events that could affect earnings and cash flows. Based on evaluation of these qualitative assessments, it was determined that there was no goodwill impairment for these years; however, goodwill may be impaired in future periods. Significant changes in the assumptions or estimates used in our impairment analyses, such as a reduction in profitability and/or cash flows, could result in non-cash goodwill impairment charges and materially affect our operating results.impairment.


Impairment of Property, Plant and Equipment and Intangibles


We review long-lived assets that are held and used for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared with the asset’s carrying amount to determine if there has been an impairment, which is calculated as the difference between the fair value of an asset and its carrying value. Estimates of future undiscounted cash flows are based on expected growth rates for the business, anticipated future economic conditions and estimates of residual values. Fair values take into consideration management’s estimates of risk-adjusted discount rates, which are believed to be consistent with assumptions that marketplacemarket participants would use in their estimates of fair value. There were no impairments of property, plant and equipment or intangible assets recognized during the years ended December 31, 2018, 20172021, 2020 and 2016.2019.

Revenue. Revenue increased by 71.3%, or $324.4 million, during the year ended December 31, 2018 as compared to the same period in 2017. The increase in revenue is primarily due to the increased project volume, coupled with larger revenue projects in 2018. The Company generated approximately $156.3 million more in revenue related to our top ten projects under construction this year compared to the prior year and, to a lesser extent, the fourth quarter revenue of $125.6 million from our acquired businesses.

Cost of revenue. Cost of revenue increased by 92.3%, or $358.9 million, during the year ended December 31, 2018 as compared to the same period in 2017, primarily due to the larger volume of business in 2018, including cost of revenue of $115.4 million from our acquired businesses. As discussed under "Impact of Seasonality and Cyclical Nature of Our Business," cost of revenue for the year was negatively impacted by multiple severe weather events that began in the late third quarter and continued into the fourth quarter of 2018. The weather conditions had a significant impact on the construction of six wind projects across South Texas, Iowa and Michigan resulting in additional labor, equipment and material costs. Although the Company is aggressively pursuing the collection of all amounts it is contractually owed due to weather-related delays, including collections on change orders resulting from force majeure provisions of certain customer contracts, at this time, the Company anticipates that these costs will not be recovered.

Gross profit. Gross profit decreased by 52.2%, or $34.5 million, during the year ended December 31, 2018 as compared to the same period in 2017. As a percentage of revenue, gross profit declined and totaled 4.0% for the year ended December 31, 2018 as compared to 14.5% in the prior-year period. The decrease in margin was primarily due to work stoppages related to extreme weather on six projects of $35.8 million coupled with a negative impact due to the previously disclosed customer dispute, both due to unbilled revenue and costs associated with the project, of approximately $8.5 million. To a lesser extent, the remaining decrease in margin also reflected early signs of labor and other cost inflation due to increasingly robust construction markets across the country.

Selling, general and administrative expenses. Selling, general and administrative expenses increased by 115.4%, or $38.7 million, during the year ended December 31, 2018 as compared to the same period in 2017. Selling, general and administrative expenses were 9.3% of revenue for the year ended December 31, 2018, compared to 7.4% for the same period in 2017. The increase in selling, general and administrative expenses was primarily driven by $14.2 million of acquisition-related expenses incurred for our 2018 acquisitions, $8.5 million of Merger-related transaction costs and $6.9 million of staffing related expenses due to higher project volume and, to a lesser extent, the fourth quarter selling, general and administrative expenses of $8.6 million from our acquired businesses.



Interest expense, net. Interest expense, net increased by 448.8%, or $9.9 million, during the year ended December 31, 2018 as compared to the same period in 2017. This increase was driven by the increased borrowings under our lines of credit to support the increased revenue base from our wind business and our new term loan to finance the acquisition of our acquired businesses.

Contingent consideration fair value adjustment. In the fourth quarter of 2018, the Company recognized a $46.3 million adjustment to the fair value of its contingent consideration incurred in connection with the Merger. The merger agreement requires the Company to issue additional shares of our common stock to the Seller if certain financial targets for 2018 and 2019 are achieved. The Company may be required to issue such shares if the 2019 financial target is achieved. The fair value calculation derived an adjustment to the liability based on 2018 actual financial results and the expected probability of reaching the full amount of contingent consideration in 2019. See Note 8. Fair Value of Financial Instruments in Item 8 for further discussion related to inputs into the fair value adjustment.
Other income (expense). Other income decreased by 2,057.7%, or $2.3 million, to an expense of $2.2 million during the year ended December 31, 2018 as compared to the same period in 2017. The decrease in other income compared to the prior year period was primarily the result of a $1.8 million loss on the extinguishment of debt recognized in 2018.

Provision for income taxes. Income tax expense decreased by 193.4%, or $26.8 million, to a benefit of $12.9 million for the year ended December 31, 2018, compared to an expense of $13.9 million for the same period in 2017. The effective tax rates for the years ended December 31, 2018 and 2017were 148.8% and 45.6%, respectively. The higher effective tax rate is primarily attributable to the permanent item pertaining to contingent consideration and state taxes, partially offset by tax law changes which reduced the federal statutory rate. The difference between the Company’s effective tax rate and the federal statutory rate primarily results from permanent adjustments and current state taxes. There were no changes in uncertain tax positions during the years ended December 31, 2018 and 2017.

Revenue. For the year ended December 31, 2017, consolidated revenue decreased to $454.9 million from $602.7 million, a decrease of approximately $147.7 million, or 24.5%, as compared with the prior year. In 2016, a refocus on U.S. wind energy construction, as well as a pull forward of volume in anticipation of a decline in tax credits in 2017, resulted in higher revenue in 2016 and caused a slow-down in projects in 2017. Ultimately, the tax credits were extended in 2017, but revenue in the fourth quarter of 2017 was negatively impacted by uncertainty caused by the legislative process for enacting the 2017 Tax Act, which caused some participants in the renewable energy industry to delay new development projects until the ultimate terms of the 2017 Tax Act could be evaluated.

Cost of revenue. Cost of revenue was $388.9 million, or 85.5% of revenue, for the year ended December 31, 2017, as compared to $517.4 million, or 85.9% of revenue, for the same period in 2016, for a decrease of approximately $128.5 million,


or 24.8%. The decrease in the dollar amount cost of revenue was primarily driven by decreased project activity. We were able to achieve a slight reduction in our cost of revenue percentage primarily through our continued focus on operating efficiency.

Gross profit. Gross profit decreased by $19.2 million, or 22.6%, to $66.0 million for the year ended December 31, 2017, as compared to $85.2 million for the same period in 2016. The decrease in 2017 gross profit was due to decreased project activity relative to the prior year. A refocus on core U.S. operations and strengthened project controls in 2016 carried over to 2017 allowing us to maintain gross profit as a percentage of revenue of 14.5%, as compared to 14.1% in 2016.
Selling, general and administrative expenses. Selling, general and administrative expenses were $33.5 million, or 7.4% of revenue for the year ended December 31, 2017, as compared to $30.7 million, or 5.1% of revenue for the same period in 2016, an increase of $2.8 million, or 9.2%. The increase in selling, general and administrative expenses was primarily driven by an increase to diversification selling, general and administrative expenses related to our recent initiatives to grow our solar and transmission businesses of $3.8 million, as well as $3.8 million consulting fees and professional expenses, offset by a decrease in payments of employee incentives.
Interest expense, net. Interest expense, net of interest income, was $2.2 million for the year ended December 31, 2017 as compared to $0.5 million for the same period in 2016. This increase was primarily driven by a significant increase in equipment financed under capital leases.

Other income. Other income was $0.1 million for the year ended December 31, 2017 as compared to $0.2 million for the same period in 2016. The decrease in other income was primarily driven by lower gains on the sale of assets in 2017.
(Provision) benefit for income taxes. Income tax provision was $13.9 million for the year ended December 31, 2017 as compared with a tax benefit of $10.2 million for the year ended December 31, 2016, an increase of approximately $24.1 million. The increase in provision for income taxes was primarily driven by the release of the valuation allowance during 2016.

Net income from discontinued operations. Net income from discontinued operations was $1.1 million for the year ended December 31, 2016 and related to the wind down of our Canadian operations that concluded in 2016.

Liquidity and Capital Resources

Our primary sources of liquidity are cash flows from operations, our cash balances and availability under our revolving credit facility. Our primary liquidity needs are for working capital, debt service, interest on our preferred stock, income taxes, capital expenditures, insurance collateral, and strategic acquisitions in the form of cash and letters of credit.

We anticipate that our existing cash balances, funds generated from operations and borrowings will be sufficient to meet our cash requirements for the next twelve months. As of December 31, 2018, we had approximately $71 million in cash and no availability under our credit facility. To the extent that cash from operations and borrowings under our revolving credit facility are not sufficient to meet our liquidity needs in the next twelve months, we expect to access other sources of liquidity through alternative sources such as issuance of debt and equity securities, expansions of our credit facility or other sources. There can be no assurance that any such sources will be available or if they are available that we can obtain capital from such sources on commercially reasonable terms.

Capital Expenditures

For the year ended December 31, 2018, we incurred $49.0 million in equipment purchases under capital lease and an additional $4.2 million in cash purchases. We estimate that we will spend approximately two percent of revenue for capital expenditures in 2019. Actual capital expenditures may increase or decrease in the future depending upon business activity levels, as well as ongoing assessments of equipment lease versus buy decisions based on short and long-term equipment requirements.

Working Capital

We require working capital to support seasonal variations in our business, primarily due to the effect of weather conditions on external construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated spending to support related customer demand. Our business is typically slower in the first quarter of each calendar year. Working capital needs are generally lower during the spring when projects are awarded and we receive down payments from customers. Conversely, working capital needs generally increase during the summer or fall months due to increased demand for our services when favorable weather conditions exist in many of the regions in which we operate. Again,


working capital needs are typically lower and working capital is converted to cash during the winter months. These seasonal trends, however, can be offset by changes in the timing of projects, which can be affected by project delays or accelerations and/or other factors that may affect customer spending.

Generally, we receive 5% to 10% cash payments from our customers upon the inception of the projects. Timing of billing milestones and project close-outs can contribute to changes in unbilled revenue. As of December 31, 2018, substantially all of our costs and estimated earnings in excess of billings on uncompleted contracts will be billed to customers in the normal course of business. Net accounts receivable balances, which consist of contract billings as well as costs and estimated earnings in excess of billings on uncompleted contracts and retainage, increased to $272.5 million as of December 31, 2018 from $79.6 million as of December 31, 2017, due primarily to higher levels of revenue, timing of project activity and collection of billings to customers.

Our billing terms are generally net 30 days, and some of our contracts allow our customers to retain a portion of the contract amount (generally, from 5% to 10%) until the job is completed. As part of our ongoing working capital management practices, we evaluate opportunities to improve our working capital cycle time through contractual provisions and certain financing arrangements. Our agreements with subcontractors often contain a ‘‘pay-if-paid’’ provision, whereby our payments to subcontractors are made only after we are paid by our customers.

Sources and Uses of Cash

Sources and uses of cash are summarized below for the periods indicated:
  Year Ended December 31,
(in thousands) 2018 2017 2016
Net cash provided by (used in) operating activities $47,018
 $(9,109) $53,591
Net cash used in investing activities (169,834) (3,508) (3,000)
Net cash provided by (used in) financing activities 189,250
 (4,113) (29,617)

Operating Activities. Net cash provided by operating activities for the year ended December 31, 2018 was $47.0 million as compared to net cash used in operating activities of $9.1 million for the same period in 2017. The increase in net cash provided by operating activities reflects the timing of receipts from customers and payments to vendors in the ordinary course of business. The increase is primarily attributable to $122.6 million less cash paid for accounts payable and accrued liabilities, coupled with a $46.6 million increase from billings in excess of costs and estimated earnings on uncompleted contracts, partially offset by $45.3 million less cash collected from accounts receivable, a decrease in operating income (excluding non-cash items) of $61.5 million and additional cash paid for interest of $8.6 million.

The $62.7 million decrease in operating cash flow for the year ended December 31, 2017 as compared to the same period in 2016 was primarily attributable to $45.1 million more cash paid for accounts payable and accrued liabilities, coupled with a $33.0 million decrease from billings in excess of costs and estimated earnings on uncompleted contracts, partially offset by $30.0 million more cash collected from accounts receivable.

Investing Activities. Net cash used in investing activities for the year ended December 31, 2018 was $169.8 million as compared to $3.5 million for the same period in 2017. The increase in net cash used in investing activities in 2018 primarily reflects the net cash paid for two acquisitions of $166.7 million. The $0.5 million decrease in investing cash flow for the year ended December 31, 2017 as compared to the same period in 2016 was due to a $1.5 million increase in use of cash for company-owned life insurance, offset by a $0.6 million decrease in property, plant and equipment purchases and a $0.4 million increase in proceeds received from the sale of property, plant and equipment.

Financing Activities. Net cash provided by financing activities for the year ended December 31, 2018 was $189.3 million as compared to net cash used in financing activities of $4.1 million for the same period in 2017. The $193.4 million increase in cash in 2018 is primarily attributable to an increase in net proceeds from debt of $189.6 million, coupled with reduced distributions of $34.7 million, which was partially offset by a $25.8 million use of cash in connection with the Merger and a $4.1 million increase in capital lease payments. The $25.5 million increase in financing cash flow for the year ended December 31, 2017 as compared to the same period in 2016 was primarily driven by $33.7 million of proceeds received from our old line of credit in 2017 compared to $27.9 million of payments in 2016, partially offset by $34.7 million of distributions in 2017.



Debt

For further discussion of our term loan facility, our revolving line of credit and corresponding debt covenants, see Note 9. Debt in the notes to our audited consolidated financial statements included in Item 8.

Letters of Credit and Surety Bonds

In the ordinary course of business, we are required to post letters of credit and surety bonds to customers in support of performance under certain contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit or surety bond commits the issuer to pay specified amounts to the holder of the letter of credit or surety bond under certain conditions. If the letter of credit or surety bond issuer were required to pay any amount to a holder, we would be required to reimburse the issuer, which, depending upon the circumstances, could result in a charge to earnings. As of December 31, 2018 and 2017, we were contingently liable under letters of credit issued under our respective revolving lines of credit in the amount of $3.0 million and $5.9 million, respectively, related to projects. In addition, as of December 31, 2018 and 2017, we had outstanding surety bonds on projects of $1.68 billion and $535.5 million, respectively, which includes the bonding lines of the acquired companies as of December 31, 2018.

(4)We lease real estate, vehicles, office equipment and certain construction equipment from unrelated parties under non-cancelable leases. Lease terms range from month-to-month to terms expiring through 2038.

Off-Balance Sheet Arrangements

As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases, letter of credit obligations, surety and performance and payment bonds entered into in the normal course of business, liabilities associated with deferred compensation plans and liabilities associated with certain indemnification and guarantee arrangements. See Note 9. Debt and Note 10. Commitments and Contingencies to our consolidated financial statements for further discussion pertaining to certain of our off-balance sheet arrangements.

Recently Issued Accounting Pronouncements


See Note 1. Business, Basis of Presentation and Significant Accounting Policies to our consolidated financial statements included in this Annual Report on 10-K for disclosures concerning recently issued accounting standards. These disclosures are incorporated herein by reference.
Backlog

For companies in the construction industry, backlog can be an indicator of future revenue streams. Estimated backlog represents the amount of revenue we expect to realize beyond 2020 from the uncompleted portions of existing construction


contracts, including new contracts under which work has not begun and awarded contracts for which the definitive project documentation is being prepared, as well as revenue from change orders and renewal options. Estimated backlog for work under fixed price contracts and cost-reimbursable contracts is determined based on historical trends, anticipated seasonal impacts, experience from similar projects and estimates of customer demand based on communications with our customers. Cost-reimbursable contracts are included in backlog based on the estimated total contract price upon completion.

As of December 31, 2018, our total backlog was approximately $2.1 billion compared to $1.1 billion as of December 31, 2017. The $1.0 billion increase is primarily related to $833.7 million of backlog related to our acquisitions coupled with $166.3 million of an increase in backlog related to our legacy IEA business. Based on historical trends in the Company’s backlog, we believe awarded contracts to be firm and that the revenue for such contracts will be recognized over the life of the project. Timing of revenue for construction and installation projects included in our backlog can be subject to change as a result of customer delays, regulatory factors and/or other project-related factors. These changes could cause estimated revenue to be realized in periods later than originally expected, or not at all. In the past, we have occasionally experienced postponements, cancellations and reductions on construction projects, due to market volatility and regulatory factors. There can be no assurance as to our customers’ requirements or the accuracy of our estimates. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings.

Backlog is not a term recognized under GAAP, although it is a common measurement used in our industry. Our methodology for determining backlog may not be comparable to the methodologies used by others. See ‘‘Item 1A. Risk Factors’’ for a discussion of the risks associated with our backlog.

Certain transactions affecting comparisons of the Company's quarterly results, which may not represent the amounts recognized for the full year for such transactions, include the following:

The Company completed a merger with a special purpose acquisition corporation in the first quarter of 2018 and therefore had significant transaction costs of $8.5 million.



There were two acquisitions completed in the second half of 2018, which contributed to Revenue and Cost of Revenue of $125.6 million and $115.4 million, respectively.

Certain projects incurred significant weather related costs in the fourth quarter of 2018, that increased costs required to complete those projects and decreased gross margin significantly.

Net income used in calculation of earnings per share reflects payment of $1.6 million of preferred dividends and an adjustment of $46.3 million for the contingent consideration fair value adjustment in 2018. See Note 11. Earnings (Loss) Per Share in the notes to the audited consolidated financial statements included in Item 8.


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK


Credit Risk


We are subject to concentrations of credit risk related to our net receivable position with customers, which includes amounts related to billed and unbilled accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts net of advanced billings with the same customer. We grant credit under normal payment terms, generally without collateral, and as a result, we are subject to potential credit risk related to our customers’ ability to pay for services provided. This risk may be heightened if there is depressed economic and financial market conditions. However, we have the ability to file lien rights to limit this exposure and we believe the concentration of credit risk related to billed and unbilled receivables and costs and estimated earnings in excess of billings on uncompleted contracts is limited because of the lack of concentration and the high creditworthiness and diversitycredit rating of our customers.


Interest Rate Risk

44
Borrowings under our new credit facility are at variable rates of interest and expose us to interest rate risk. As of December 31, 2018, we had not entered into any derivative financial instruments to manage this interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. Our outstanding principal on debt as of December 31, 2018 was $351.8 million. A one hundred basis point change in the LIBOR rate would increase or decrease interest expense by $3.5 million.

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.

Critical Audit Matter

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

Revenue Recognition for Unapproved Change Orders – Refer to Note 1 to the Financial Statements

Critical Audit Matter Description

Revenue from construction contracts is recognized over time using the cost-to-cost measure of progress. Management reviews estimates of total contract transaction price and total project costs on an ongoing basis. Changes in job performance, job conditions, and management’s assessment of expected variable considerations are factors that influence estimates of the total contract transaction price, total costs to complete those contracts, and profit recognition.

Transaction pricing for the Company’s contracts may include variable consideration, including items such as change orders. Management estimates variable consideration for a performance obligation utilizing estimation methods that best predict the amount of consideration to which the Company will be entitled. Variable consideration is included in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Management’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based on past practices with the customer, specific discussions, correspondence or preliminary negotiations with the customer, legal evaluations, and all other relevant information that is reasonably available.

To the extent unapproved change orders are not resolved in the Company’s favor, there could be reductions in, or reversals of, previously recognized revenue. As of December 31, 2021, the Company included approximately $94.5 million of unapproved change orders in the transaction price for certain contracts that were in the process of being resolved in the normal course of business, including through negotiation, arbitration, and other proceedings.

We identified revenue recognition related to unapproved change orders as a critical audit matter because of the judgments necessary for management to determine the variable consideration related to unapproved change orders and the extent of audit effort and degree of auditor judgment when performing procedures to audit management’s estimates of revenue related to unapproved change orders.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s estimates of variable consideration related to unapproved change orders used in the transaction price to recognize revenue on construction contracts included the following, among others:

We tested the effectiveness of controls over the Company’s unapproved change orders and estimates of variable consideration.

We tested the mathematical accuracy of management’s calculation of revenue recognized from unapproved change orders.

We compared historical estimates of variable consideration to actual results to evaluate management’s estimates.

For a selection of contracts identified with significant unapproved change orders, we performed the following:

Evaluated the Company’s variable consideration against the contract provisions.

Evaluated details of the underlying costs included in the unapproved change orders.

Obtained available correspondence with customers.

Performed inquiries with project management and executive management, including those independent of accounting.

Obtained a legal evaluation of the contractual provisions from internal counsel.

INFRASTRUCTURE AND ENERGY ALTERNATIVES, INC.
Notes to Consolidated Financial Statements


Note 1. Business, Basis of Presentation and Significant Accounting Policies


Infrastructure and Energy Alternatives, Inc. (f/k/a M III Acquisition Corporation (“M III”)), a Delaware corporation, is a holding company organized on August 4, 2015 (together with its wholly-owned subsidiaries, “IEA” or the “Company”).


On March 26, 2018 (the “Closing Date”), the Company consummated a merger (the “Merger”) pursuant to an Agreement and Plan of Merger, dated November 3, 2017 (as amended, the “Merger Agreement”), by and among M III, IEA Energy Services, LLC (“IEA Services”), a Delaware limited liability company, Infrastructure and Energy Alternatives, LLC (the “Seller”), a Delaware limited liability company and the parent of IEA Services immediately prior to such time, and the other parties thereto, which provided for, among other things, the merger of IEA Services with and into a wholly-owned subsidiary of M III. Following the Merger, M III Acquisition Corporation changed its name to Infrastructure and Energy Alternatives, Inc. See Note 2. Merger, Acquisitions and Discontinued Operations for more information about the Merger.
On September 25, 2018, IEA Services completed its acquisition of Consolidated Construction Solutions I LLC (“CCS”), a provider of environmental and industrial engineering services through its wholly-owned subsidiaries, Saiia LLC (“Saiia”) and American Civil Constructors LLC (the “ACC Companies”). On November 2, 2018, IEA Services completed its acquisition of William Charles Construction Group, including its wholly-owned subsidiary Ragnar Benson (“William Charles”), a provider of engineering and construction solutions for the rail infrastructure and heavy civil construction industries. See Note 2. Merger, Acquisitions and Discontinued Operations for further discussion of these acquisitions.
The Company specializes in providing complete engineering, procurement and construction (“EPC”) services throughout the United States (“U.S.”) for the renewable energy, traditional power and civil infrastructure industries. These services include the design, site development, construction, installation and restoration of infrastructure. Although the Company has historically focused on the wind industry, its recentbut has recently focused on further expansion into the solar market and with our 2018 acquisitions have expanded its construction capabilities and geographic footprint in the areas of renewables, environmental remediation, industrial maintenance, specialty paving, heavy civil and rail infrastructure construction, creating a diverse national platform of specialty construction capabilities.
Reportable Segments

    The Company has 2 reportable segments: the Renewables (“Renewables”) segment and the Heavy Civil and Industrial (“Specialty Civil”) segment. See Note 13. Segments for a description of the reportable segments and their operations.

Principles of Consolidation


The accompanying consolidated financial statements include the accounts of Infrastructure and Energy Alternatives, Inc. and its wholly-owned direct and indirect domestic and foreign subsidiaries: IEA Intermediate Holdco, LLCsubsidiaries. The Company occasionally forms joint ventures with unrelated third parties for the execution of single contracts or projects. The Company assesses its joint ventures to determine if they meet the qualifications of a variable interest entity (“Holdings”VIE”), IEA Services, IEA Management Services, Inc., IEA Constructors, Inc. (f/k/a IEA Renewable, Inc. in accordance with Accounting Standard Codification (“ASC”), White Construction, Inc. (“White”), White Electrical Constructors, Inc., IEA Equipment Management, Inc., White’s wholly-owned subsidiary H.B. White Canada Corp. (“H.B. White”), and from their date of acquisition, CCS and William Charles. Topic 810, Consolidation. For construction joint ventures that are not VIEs or fully consolidated but for which the Company has significant influence, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, see Note 14. Joint Ventures. All intercompany accounts and transactions are eliminated in consolidation.

The Company operates in one reportable segment, providing EPC services. Operations prior to the Merger are the historical operations of IEA Services as discussed in Note 2. Merger, Acquisitions and Discontinued Operations.


Basis of Accounting and Use of Estimates


The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”). The preparation of the consolidated financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Key estimates include: the recognition of revenue and project profit or loss (which the Company defines as project revenue less project cost of revenue), in particular, onfrom construction contracts accounted for under the percentage-of completion method, for which the recorded amounts require estimates of costs to complete projects, ultimate project profit and the amount of probable contract price adjustments as inputs;projects; fair value estimates including those related to acquisitions and contingent consideration;warrant liabilities; valuations of goodwill and intangible assets; asset lives used in computing depreciation and amortization; accrued self-insured claims; other reserves and accruals; accounting for income taxes; and the estimated impact of contingencies and ongoing litigation. While management believes that such estimates are reasonable when considered in conjunction with the Company’s consolidated financial position and results of operations, actual results could differ materially from those estimates.



“Emerging Growth Company” Reporting Requirements


The Company qualifies as an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). For as long as a company is deemed to be an “emerging growth company,” it may take advantage of specified reduced reporting and other regulatory requirements that are generally unavailable to other public companies. Among other things, the Company is not required to provide an auditor attestation report on the assessmentprior period classification of the internal control over financial reporting under Section 404(b)warrant liability fair value adjustment for the Series B Preferred Stock - Anti-dilution warrants has been revised to conform to the current period presentation within the Consolidated Statements of the Sarbanes-Oxley Act of 2002. Section 107 of the JOBS Act also provides that an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The CompanyOperations. This reclassification has elected to take advantage of this extended transition period. The Company's financial statements may therefore not be comparable to those of companies that comply with such newno effect on net income or revised accounting standards.stockholders' equity.

The Company would cease to be an “emerging growth company” upon the earliest of:
the last day of the fiscal year following July 6, 2021, the five-year anniversary of the completion of M III's initial public offering;
the last day of the fiscal year in which the Company's total annual gross revenues exceed $1.07 billion;
the date on which the Company has, during the previous three-year period, issued more than $1 billion in non-convertible debt securities; or
the date on which the Company becomes a “large accelerated filer,” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of the Company's common stock held by nonaffiliates exceeds $700 million as of the last day of its most recently completed second fiscal quarter.

The Company continues to monitor its status as an “emerging growth company” and is currently preparing, and expects to be ready to comply with, the additional reporting and regulatory requirements that will be applicable when it ceases to qualify as an “emerging growth company.”


Cash and Cash Equivalents


The Company considers all unrestricted, highly liquid investments with a maturity of three months or less when purchased to be cash and cash equivalents. The Company maintains cash balances in various United States (“US”)-backed banks, which, at times, may exceed the amounts insured by the Federal Deposit Insurance Corporation.


Accounts Receivable


The Company does not accruecharge interest to its customers and carries its customer receivables at their face amounts, less an allowance for doubtful accounts.credit losses. Accounts receivable and contract assets include amounts billed to customers under the terms and provisions of the contracts. Most billings are determined based on contractual terms. Included in accounts receivable are balances billed to customers pursuant to retainage provisions in certain contracts that are due upon completion of the contract and acceptance by the customer, or earlier as provided by the contract. As is common practice in the industry, the Company classifies all accounts receivable and contract assets, including retainage, as current assets. The
54


contracting cycle for certain long-term contracts may extend beyond one year, and accordingly, collection of retainage on those contracts may extend beyond one year. Accounts receivableContract assets include amounts billed to customers under retention provisions in construction contracts. Such provisions are standard in the Company’s industry and usually allow for a small portion of progress billings on the contract price, typically 10%5-10%, to be withheld by the customer until after the Company has completed work on the project. Based on the Company’s experience with similar contracts in recent years, billingsBillings for such retention balances at each balance sheet date are finalized and collected after project completion. Generally, unbilled amounts will be billed and collected within one year. The Company determined that there are no material amounts due past one year and no material amounts billed but not expected to be collected within one year.


As noted in the Recently Adopted Accounting Standards section below, the Company adopted the new accounting standard for measuring credit losses effective January 1, 2021 utilizing the transition method that allows recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company grants tradeCompany's financial results for reporting periods beginning on or after January 1, 2021 are presented under the new standard, while financial results for prior periods continue to be reported in accordance with the prior standard and the Company's historical accounting policy. The net cumulative effect due to the adoption of the new standard did not have an impact to retained earnings as of January 1, 2021. Although the adoption of the new standard did not have a material impact on the Company's consolidated financial statements at the date of adoption, expected credit onlosses could change as a non-collateralized basis, to its customers and is subject to potential credit risk related toresult of changes in business and overall economic activity. The Company analyzescredit loss experience, changes to specific accounts receivable balances, historical bad debts, customer credit-worthiness, current economic trends and changes in customer payment terms when evaluating the adequacyrisk characteristics of the Company's portfolio of financial assets or changes to management’s expectations of future economic conditions that affect the collectability of the Company's financial assets. At the end of each quarter, management reassesses these factors.

Revenue Recognition


The Company adopted the requirements of Accounting Standards Update (“ASU”) 2014-09, Revenue under construction contractsfrom Contracts with Customers, which is accounted foralso referred to as Accounting Standards Codification (“ASC”) Topic 606, under the percentage-of-completion method of accounting. Under the percentage-of-completion method, the Company estimates profit as the difference between total estimated revenue and total estimated cost of a contract and recognizes that profit over the contract term based on costs incurred. Contract costs includemodified retrospective transition approach effective January 1, 2019, with application to all direct materials, labor and subcontracted costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, depreciation and the operational costs of capital equipment. The Company also has unit-priceexisting contracts that were not significantsubstantially completed as of January 1, 2019. The impacts of adoption on the Company’s retained earnings on January 1, 2019 was primarily related to variable consideration on unapproved change orders. The cumulative impact of adopting Topic 606 required net adjustments of $750,000 to the statement of operations among revenue, cost of revenue and income taxes, thereby reducing income for the year ended December 31, 2018.2019 and reducing the December 31, 2019 accumulated deficit. The Company also adjusted the December 31, 2019, statement of cash flows to reflect the impact of adoption.

The estimation process for    Under Topic 606, revenue is recognized when control of promised goods and services is transferred to customers, and the amount of revenue recognized underreflects the percentage-of-completion methodconsideration to which an entity expects to be entitled in exchange for the goods and services transferred. Revenue is recognized by the Company primarily over time utilizing the cost-to-cost measure of progress for fixed price contracts and is based on the professional knowledgecosts for time and experience ofmaterials and other service contracts, consistent with the Company’s project managers, engineersprevious revenue recognition practices.
    The adoption of Topic 606 did not have a material effect on the Company's consolidated financial statements; related to revenues, contract assets/liabilities, deferred taxes and financial professionals. Management reviews estimates of contract revenue and costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of expected contract settlements are factors that influence estimates of total contract value and total costs to complete those contracts and, therefore,net loss as compared with the Company’s profit recognition. Changes in these factors may result in revisions to costsprevious revenue recognition practices under ASC Topic 605.
Contracts
    The Company derives revenue primarily from construction projects performed under contracts for specific projects requiring the construction and income,installation of an entire infrastructure system or specified units within an infrastructure system. Contracts contain multiple pricing options, such as fixed price, time and their effectsmaterials, or unit price. Generally, renewable energy projects are recognized in the period in which the revisionsperformed for private customers while Specialty Civil projects are determined, which could materially affect the Company’s results of operations in the period in which such changes are recognized.performed for various governmental entities.

Revenue derived from projects billed on a time and materials basis totaled 3.8%1.1%, 2.2%2.3% and 9.6%5.2% of consolidated revenue from continuing operations for the years ended December 31, 2018, 20172021, 2020 and 2016,2019, respectively.


ForConstruction contract revenue is recognized over time using the cost-to-cost measure of progress for fixed price contracts. The cost-to-cost measure of progress best depicts the continuous transfer of control of goods or services to the customer. The contractual terms provide that the customer compensates the Company for services rendered.
Contract costs include all direct materials, labor and subcontracted costs, as well as indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and the costs of capital equipment. The cost estimation and review process for recognizing revenue over time under the cost-to-cost method is based on the professional knowledge and experience of the Company’s project managers, engineers and financial professionals. Management reviews estimates of total contract transaction price and total project costs on an approved change order which can be reliably estimated asongoing basis. Changes in job performance, job conditions and management’s assessment of expected variable consideration are factors that influence estimates of the total contract transaction price, total costs to price, the anticipated revenuescomplete those contracts and profit recognition. Changes in these factors could result in revisions to revenue and costs of revenue in the period in which the revisions are determined on a prospective basis, which could materially affect the Company’s consolidated results of operations for that period. Provisions for losses on uncompleted contracts are recorded in the period in which such losses are determined.
Performance Obligations
    A performance obligation is a contractual promise to transfer a distinct good or service to the customer and is the unit of account under Accounting Standards Codification (“ASC”) Topic 606. The transaction price of a contract is allocated to distinct performance obligations and recognized as revenue when or as the performance obligations are satisfied. The Company’s contracts often require significant integrated services and, even when delivering multiple distinct services, are generally accounted for as a single performance obligation. Contract amendments and change orders are generally not distinct from the existing contract due to the significant integrated service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. With the exception of certain Specialty Civil service contracts, the majority of the Company’s performance obligations are completed within one year.
    When more than one contract is entered into with a customer on or close to the same date, the Company evaluates whether those contracts should be combined and accounted for as a single contract as well as whether those contracts should be accounted for as more than one performance obligation. This evaluation requires significant judgment and is based on the facts and circumstances of the various contracts, which could change the amount of revenue and profit recognition in a given period depending upon the outcome of the evaluation.
    Remaining performance obligations represent the amount of unearned transaction prices for fixed price contracts and open purchase orders for which work is wholly or partially unperformed. As of December 31, 2021, the amount of the Company’s remaining performance obligations was $2.0 billion. The Company expects to recognize approximately 81.8% of its remaining performance obligations as revenue in 2022, with the remainder recognized primarily in 2023. Revenue recognized from performance obligations satisfied in previous periods was $2.0 million and $(10.0) million for the years ended December 31, 2021 and 2020, respectively.
Variable Consideration
    Transaction pricing for the Company’s contracts may include variable consideration, such as unapproved change orders, claims, incentives and liquidated damages. Management estimates variable consideration for a performance obligation utilizing estimation methods that best predict the amount of consideration to which the Company will be entitled. Variable consideration is included in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Management’s estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based on past practices with the customer, specific discussions, correspondence or preliminary negotiations with the customer, legal evaluations and all other relevant information that is reasonably available. The effect of a change orderin variable consideration on the transaction price of a performance obligation is typically recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders, claims and liquidated damages reflected in transaction price are addednot resolved in the Company’s favor, or to the total contract valueextent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.

When costs are incurred for a) anCompany included approximately $94.5 million and $52.6 million, respectively, on unapproved change order which is probable to be approved orders and/or b) an approved change order which cannot be reliably estimatedclaims in the transaction price for certain contracts that were in the process of being resolved in the normal course of business, including through negotiation, arbitration and other proceedings.

Once a change order becomes approved and reliably estimable, any margin related to the change order is added to the total contract value of the project.appropriate. The Company actively engages in substantive meetings with its customers to complete the final approval process, and generally expects these processes to be completed within aone year. The amountsAmounts ultimately realized upon final acceptance by its customers could be higher or lower than such estimated amounts.


ProvisionsDisaggregation of Revenue
    The following tables disaggregate revenue by customers and services performed, which the Company believes best depicts how the nature, amount, timing and uncertainty of its revenue for losses on uncompleted contracts are made in the period in which such losses become evident. The Company may incur costs subject to change orders, whether approved or unapproved by the customer, and/or claims related to certain contracts. Management determines the probability that such costs will be recovered based upon engineering studies and legal opinions, past practices with the customer and specific discussions, correspondence and/or preliminary negotiations with the customer.years ended:

Construction Joint Ventures


Classification of Construction Contract-Related Assets and Liabilities

Contract costs include all direct subcontract, material and labor costs, and those indirect costs related to contract
performance, such as indirect labor, supplies, tools, insurance, repairs, maintenance, communications and use of Company-owned equipment. Contract revenues are earned and matched with related costs as incurred.

Costs and estimated earnings in excess of billings on uncompletedCertain contracts are presentedexecuted through joint ventures. The arrangements are often formed for the execution of single contracts or projects and allow the Company to share risks and secure specialty skills required for project execution.
In accordance with ASC Topic 810, Consolidation, the Company assesses its joint ventures at inception to determine if any meet the qualifications of a VIE. The Company considers a joint venture a VIE if either (a) the total equity investment is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or their rights to receive the expected residual returns of the entity and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events outlined in ASC 810, the Company reassesses its initial determination of whether the joint venture is a VIE.
The Company also evaluates whether it is the primary beneficiary of each VIE and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the entity, and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company considers the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining whether it qualifies as the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when
57


determining whether it is the primary beneficiary. When the Company is determined to be the primary beneficiary, the VIE is consolidated. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a current assetVIE is performed continuously.
Construction joint ventures that do not involve a VIE, or for which the Company is not the primary beneficiary, are evaluated for consolidation under the voting interest model that considers whether the Company owns or controls more than 50% of the voting interest in the accompanyingjoint venture. For construction joint ventures that are not consolidated balance sheets, and billings in excess of costs and estimated earnings on uncompleted contracts are presented as a current liabilitybut for which the Company has significant influence, the Company accounts for its interest in the accompanyingjoint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated balance sheets. The Company’s contracts vary in duration, with the duration of some larger contracts exceeding one year. Consistent with industry practice, the Company includes the amounts realizable and payable under contracts, which may extend beyond one year, in current assets and current liabilities. These balances are generally settled within one year.

financial statements. See Note 14. Joint Ventures for additional discussion regarding joint ventures.
Self-Insurance

The Company is self-insured up to the amount of its deductible for its medical and workers’ compensation insurance policies. For the years ended December 31, 2018, 20172021, 2020 and 2016,2019, the Company maintained insurance policies subject to per claim deductibles of $0.5 million, for its workers' compensation policy. Liabilities under these insurance programs are accrued based upon management’s estimates of the ultimate liability for claims reported and an estimate of claims incurred but not reported with assistance from third-party actuaries. The Company’s recorded liability for employee group medical claims is based on analysis of historical claims experience and specific knowledge of actual losses that have occurred. The Company is also required to post letters of credit and provide cash collateral to certain of its insurance carriers and to obtain surety bonds in certain states.


The Company’s self-insurance liability is reflected in the consolidated balance sheets within accrued liabilities. The determination of such claims and expenses and the appropriateness of the related liability is reviewed and updated quarterly, however, these insurance liabilities are difficult to assess and estimate due to unknown factors, including the severity of an injury, the determination of the Company’s liability in proportion to other parties and the number of incidents not reported. Accruals are based upon known facts and historical trends. Although management believes its accruals are adequate, a change in experience or actuarial assumptions could materially affect the Company’s results of operations in a particular period. As of December 31, 2018 and 2017, the gross amount accrued for medical insurance claims totaled $0.6 million and $0.4 million, respectively, and the gross amount accrued for workers’ compensation claims totaled $2.1 million and $1.7 million, respectively. For the years ended December 31, 2018, 2017 and 2016, health care expense totaled $2.4 million, $1.1 million and $5.0 million, respectively, and workers' compensation expense totaled $5.8 million, $3.4 million and $3.2 million, respectively.


Company-Owned Life Insurance


The Company has life insurance policies on certain key executives. Company-owned life insurance is recorded at its cash surrender value or the amount that can be realized.


As of December 31, 20182021 and 2017,2020, the Company had a long-term asset of $3.9$4.9 million and $4.3 million, respectively, related to these policies. For the years ended December 31, 2018, 20172021, 2020 and 2016,2019, the Company recognized an increase of $694, a decrease of $0.4 million$502 and increasesan increase of $2.0 million and $0.5 million,$898, respectively, in the cash surrender value of these policies.


Leases


    In the ordinary course of business, the Company enters into agreements that provide financing for machinery and equipment and for other of its facility, vehicle and equipment needs. The Company reviews all arrangements for potential leases, and at inception, determines whether a lease is an operating or finance lease. Lease assets and liabilities, which generally represent the present value of future minimum lease payments over the term of the lease, are recognized as of the commencement date. Leases with an initial lease term of twelve months or less are classified as short-term leases and are not recognized in the consolidated balance sheets unless the lease contains a purchase option that is reasonably certain real estate, construction equipmentto be exercised.

    Lease term, discount rate, variable lease costs and office equipment.future minimum lease payment determinations require the use of judgment and are based on the facts and circumstances related to the specific lease. Lease terms are generally based on their initial non-cancelable terms, unless there is a renewal option that is reasonably certain to be exercised. Various factors, including economic incentives, intent, past history and business need are considered to determine if a renewal option is reasonably certain to be exercised. The implicit rate in a lease agreement is used when it can be determined. Otherwise, the Company's incremental borrowing rate, which is based on information available as of the lease commencement date, including applicable lease terms and conditions of leases (such as renewal or purchase options and escalation clauses), if material, are reviewed at inceptionthe current economic environment, is used to determine the classification (operating or capital)value of the lease. Nonperformance-related default covenants, cross-default provisions, subjective default provisions and material adverse change clauses contained in material lease agreements, if any, are also evaluated to determine whether those clauses affect lease classification.obligation.

Property, Plant and Equipment, Net


Property, plant and equipment is recorded at cost, or if acquired in a business combination, at the acquisition-date fair value.value, less accumulated depreciation. Depreciation of property, plant and equipment, including property and equipment under capital leases, is computed using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful lives of the improvements. Expenditures for repairs and maintenance are charged to expense as incurred, and expenditures for betterments and major improvements are capitalized and depreciated over the remaining useful lives of the assets. The carrying amounts of assets sold or retired and the related accumulated depreciation are eliminated in the year of disposal, with resulting gains or losses included in other income or expense.cost of revenue.


The assets’ estimated lives used in computing depreciation for property, plant and equipment are as follows:
Buildings and leasehold improvements2 to 39 years
Construction equipment3 to 15 years
Office equipment, furniture and fixtures3 to 7 years
Vehicles3 to 5 years


Intangible Assets, Net


The Company's intangible assets represent finite-lived assets that were acquired in a business combination, consisting of customer relationships, trade names and backlog, and are recorded at acquisition-date fair value.value, less accumulated amortization. These assets are amortized over their estimated lives, which are generally based on contractual or legal rights. Amortization of customer relationship and trade name intangibles is recorded within selling, general and administrative expenses in the consolidated statements of operations, and amortization of backlog intangibles is recorded within cost of revenue. The straight-line method of amortization is used because it best reflects the pattern in which the economic benefits of the intangibles are consumed or otherwise used up. The amounts and useful lives assigned to intangible assets acquired impact the amount and timing of future amortization.


Impairment of Property, Plant and Equipment and Intangibles


Management reviews long-lived assets that are held and used for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared with the asset’s carrying amount to determine if there has been an impairment, which is calculated as the difference between the fair value of an asset and its carrying value. Estimates of future undiscounted cash flows are based on expected growth rates for the business, anticipated future economic conditions and estimates of residual values. Fair values take into consideration management’s estimates of risk-adjusted discount rates, which are believed to be consistent with assumptions that marketplace participants would use in their estimates of fair value. There were no impairments of property, plant and equipment or intangible assets recognized during the years ended December 31, 2018, 20172021, 2020 and 2016.2019.


Goodwill


Goodwill represents the excess purchase price paid over the fair value of acquired intangible and tangible assets. The Company applies the provisions of Accounting Standards Codification (“ASC”) Topic 350, Intangibles - Goodwill and Other. Accordingly, goodwill is not amortized but rather is assessed at least annually for impairment on JulyOctober 1st and tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. The Company may assess its goodwill for impairment initially using a qualitative approach to determine whether conditions exist to indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value. If management concludes, based on its assessment of relevant events, facts and circumstances, that it is more likely than not that a reporting unit’s carrying value is greater than its fair value, then a quantitative analysis will be performed to determine if there is any impairment.


The Company may also elect to initially perform a quantitative analysis instead of starting with a qualitative approach. The quantitative assessment for goodwill was historicallyrequires us to estimate the fair value of each reporting unit carrying goodwill using a two-step process. As discussed below, as of January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2017-04, Intangibles - Goodwill and Other, Simplifying the Accounting for Goodwill Impairment, which removed the second stepweighted combination of the quantitative goodwill impairment test. The first (and now final) step requires comparing the carrying value of a reporting unit, including goodwill, to its fair value using the income approach.and market approaches. The income approach uses a discounted cash flow model, which involves significant estimates and assumptions including preparation of revenue and profitability growth forecasts, selection of a discount rate and selection of a terminal year multiple.long-term growth rate. The market approach uses an analysis of stock prices and enterprise values of a set of guideline public companies to arrive at a market multiple that is used to estimate fair value. If the fair value of the respective reporting unit exceeds its carrying amount, goodwill is not


considered to be impaired. If the carrying amount of a
59


reporting unit exceeds its fair value, the Company would record an impairment charge equal to the difference, not to exceed the carrying amount of goodwill.


For the years ended December 31, 2018, 2017 and 2016, managementManagement performed a qualitative assessment for the goodwill recorded in its goodwillRenewables and Specialty Civil reporting units by examining relevant events and circumstances that could have an affecteffect on its fair value, such as macroeconomic conditions, industry and market conditions, entity-specific events, financial performance and other relevant factors or events that could affect earnings and cash flows. Based on evaluation of these qualitative assessments, it was determined that there was no goodwill impairment for these years.impairment.

Business Combinations

The Company accounts for its business combinations in accordance with ASC 805, Business Combinations, which requires an acquirer to recognize and measure in its financial statements the identifiable assets acquired, the liabilities assumed and any non-controlling interests (if applicable) in the acquiree at the acquisition date. The purchase is accounted for using the acquisition method, and the fair value of purchase consideration is allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair values. The excess, if any, of the fair value of the purchase consideration over the fair value of the identifiable net assets is recorded as goodwill. Conversely, the excess, if any, of the net fair values of the identifiable net assets over the fair value of the purchase consideration is recorded as a gain. The fair values of net assets acquired are calculated using expected cash flows and industry-standard valuation techniques, and these valuations require management to make significant estimates and assumptions. These estimates and assumptions are inherently uncertain, and as a result, actual results may materially differ from estimates. Significant estimates include, but are not limited to, future expected cash flows, useful lives and discount rates. During the measurement period, which is one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to either goodwill or gain, depending on whether the fair value of purchase consideration is in excess of or less than net assets acquired. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. Acquisition costs related to business combinations are expensed as incurred.


Contingent Consideration


As part of the Merger,merger (the “Merger”) completed with M III on March 26, 2018 (the “Closing Date”), the Company agreed to issue additional common shares to the Seller upon satisfaction of financial targets for 2018 and 2019. This contingent liability, which iswas presented as contingent consideration in the consolidated balance sheet,sheets, was measured at its estimated fair value as of the Closing Date using a Monte Carlo simulation and subsequent changes in fair value arewere recorded within other (expense) income, net in the consolidated statement of operations. See Note 8.6. Fair Value of Financial Instruments for further discussion.


Debt Issuance Costs


Financing costs incurred with securing a term loanthe Senior Unsecured Notes are deferred and amortized to interest expense, net over the maturity of the respective loan using the effective interest methodagreement on a straight-line basis and are presented as a direct deduction from the carrying amount of the related debt. Financing costs incurred with securing a revolving line of credit are deferred and amortized to interest expense, net over the contractual term of the arrangement on a straight-line basis and are presented as a direct deduction from the carrying amount of the related debt. The loss on extinguishment of debt is recognized in income in the period of extinguishment and calculated as the difference between the reacquisition price (remaining principal balance, excluding accrued and unpaid interest) and the net carrying amount of the related debt. The net carrying amount of the related debt represents the amount due at maturity, adjusted for unamortized debt issuance costs.


Stock-Based Compensation


IEA has an equity plan which    The 2018 Equity Plan grants stock options (“Options”) and, restricted stock units (“RSUs”) and performance stock units (“PSUs”) to certain key employees and members of the Board of Directors of the Company (the “Board”) for their services on the Board.services. The Company recognizes compensation expense for these awards in accordance with the provisions of ASC 718, Stock Compensation, which requires the recognition of expense related to the fair value of the awards in the Company’s consolidated statement of operations.


The Company estimates the grant-date fair value of each award at issuance. For awards subject to service-based vesting conditions, the Company recognizes compensation expense equal to the grant-date fair value on a straight-line basis over the requisite service period, which is generally the vesting term. Forfeitures are accounted for when incurred. For awards subject to both performance and service-based vesting conditions, the Company recognizes stock-based compensation expense using the straight-line recognition method when it is probable that the performance condition will be achieved.





Income Taxes


Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated 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 in effect for the year in which those temporary differences are expected to be recovered or settled. Where applicable, the Company records a valuation allowance to reduce any deferred tax assets that it determines will not be realizable in the future.


On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “2017 Tax Act”), which enacted major changes to the U.S. tax code, including a reduction in the U.S. federal corporate income tax rate from 35% to 21%, effective January 1, 2018. As a result, the Company’s U.S. deferred income tax balances were required to be remeasured in 2017. Management considered the implications of the 2017 Tax Act, including the rate change, 100% immediate expensing, toll charge, Alternative Minimum Tax (“AMT”) credit change and state impacts on the calculation of the provision for income taxes for the year ended December 31, 2017. The effect of these changes in tax law was $0.3 million, which the Company recognized within the provision for income taxes in the consolidated statement of operations for the year ended December 31, 2017.

The Company recognizes the benefit of an uncertain tax position that it has taken or expects to take on income tax returns it files if such tax position is more likely than not to be sustained on examination by the taxing authorities, based on the technical merits of the position. These tax benefits are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.


60


Litigation and Contingencies


Accruals for litigation and contingencies are reflected in the consolidated financial statements based on management’s assessment, including advice of legal counsel, of the expected outcome of litigation or other dispute resolution proceedings and/or the expected resolution of contingencies. Liabilities for estimated losses are accrued if the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated. Significant judgment is required in both the determination of probability of loss and the determination as to whether the amount is reasonably estimable. Accruals are based only on information available at the time of the assessment due to the uncertain nature of such matters. As additional information becomes available, management reassesses potential liabilities related to pending claims and litigation and may revise its previous estimates, which could materially affect the Company’s results of operations in a given period.


Fair Value of Financial Instruments


The Company applies ASC 820, Fair Value Measurement, which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances.


The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below:
Level 1 - Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities.
Level 2 - Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.


Level 3 - Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions and valuation techniques when little or no market data exists for the assets or liabilities. The Company has Series B Preferred Stock, Warrants and the Rights Offering value in Level 3.


Fair values of financial instruments are estimated using public market prices, quotes from financial institutions and other available information.


Segments


Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision makers are the chief executive officer and chief financial officer. The Company operates as a single segment and therefore reports its operations as onetwo reportable segment.segments.

Discontinued Operations

The Company accounts for business dispositions, businesses held for sale and abandonments in accordance with ASC 205-20, Discontinued Operations. ASC 205-20 requires the results of operations of business dispositions to be segregated from continuing operations and reflected as discontinued operations in current and prior periods. See Note 2. Merger, Acquisitions and Discontinued Operations for further information.


Recently Adopted Accounting Standards - Guidance Adopted in 20182021


In March 2016,December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows. This ASU, which the Company adopted early (based on its “emerging growth company” status) as of January 1, 2018, did not have a material effect on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statementof Cash Flows Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 230), Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 eliminates the diversity in practice related to the classification of certain cash receipts and payments for debt prepayment or extinguishment costs, the maturing of a zero-coupon bond, the settlement of contingent liabilities arising from a business combination, proceeds from insurance settlements, distributions from certain equity method investees and beneficial interests obtained in a financial asset securitization. ASU 2016-15 designates the appropriate cash flow classification, including requirements to allocate certain components of these cash receipts and payments among operating, investing and financing activities, and is required to be applied retrospectively. This ASU, which the Company adopted early (based on its “emerging growth company” status) as of January 1, 2018, did not have a material effect on the Company’s consolidated statements of cash flows.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350),740): Simplifying the Accounting for Goodwill Impairment. ASU 2017-04Income Taxes,” which removes the second step of the two-step goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The standard must be applied on a prospective basis. This ASU, which the Company adopted early as of January 1, 2018, did not have a material effect on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business, which amends the current definition of a business. Under ASU 2017-01, to be considered a business, an acquisition would have to include an input and a substantive process that together significantly contributescertain exceptions to the ability to create outputs. ASU 2017-01 further states that when substantially all of the fair value of gross assets acquired is concentrated in a single asset (or a group of similar assets), the assets acquired would not represent a business. The new guidance also narrows the definition of the term “outputs” to be consistent with how it is describedgeneral principles in Topic 606, Revenue from Contracts with Customers. The changes740 and also clarifies and amends existing guidance to the definition of a business will likely result in more acquisitions being accounted for as asset acquisitions. The amendments should be applied prospectively on or after the effective dates. Accordingly, the Company’s early adoption of this ASU (based on its “emerging growth company” status) as of January 1, 2018 did not have an impact on the Company’s historical financial statements. Based on the Company’s evaluation of the new guidance, the Company determined that its


acquisition of CCS and its acquisition of William Charles both qualify to be accounted for as business combinations. See Note 2. Merger, Acquisitions and Discontinued Operations for further discussion of these acquisitions.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. This ASU was effective upon issuance and added seven paragraphs to ASC 740, Income Taxes, that contain Securities and Exchange Commission (“SEC”) guidance related to the application of GAAP when preparing an initial accounting of the income tax effects of the 2017 Tax Act which, among other things, allows for a measurement period not to exceed one year for companies to finalize the provisional amounts recorded as of December 31, 2017. Accordingly, the Company finalized its initial accounting of the income tax effects of the 2017 Tax Act during the year ended December 31, 2018, with no adjustments to the provisional amounts initially recognized as of December 31, 2017.

Recently Issued Accounting Standards Not Yet Adopted
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which replaces most existing revenue recognition guidance in GAAP. The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the company expects to receive in exchange for those goods or services. To achieve this core principle, the guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. The guidance addresses several areas including transfer of control, contracts with multiple performance obligations and costs to obtain and fulfill contracts. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued additional guidance deferring the effective date for one year while allowing entities the option to adopt one year early. For public companies, the guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that annual reporting period. For as long as the Company remains an “emerging growth company,” the guidance will be effective for its fiscal year 2019 annual financial statements and for interim periods beginning in fiscal year 2020. Under the guidance, there are two acceptable adoption methods: (i) full retrospective adoption to each prior reporting period presented with the option to elect certain practical expedients; or (ii) modified retrospective adoption with the cumulative effect of initially applying the guidance recognized at the date of initial application and providing certain additional disclosures. The Company continues to evaluate the impact the adoption of this new standard will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02,Leases (Topic 842), which is effective for annual reporting periods beginning after December 15, 2018. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 requires entities to adopt the new lease standard using a modified retrospective method and initially apply the related guidance at the beginning of the earliest period presented in the financial statements. During July 2018, the FASB issued ASU 2018-11, which allows for an additional and optional transition method under which an entity would record a cumulative-effect adjustment at the beginning of the period of adoption. See Note 10. Commitments and Contingencies for additional information about the Company's leases. For as long as the Company remains an “emerging growth company,” the new guidance will be effective for its fiscal year 2020 annual financial statements and for the interim statements beginning in fiscal year 2020.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates certain disclosure requirements for recurring and non-recurring fair value measurements, such as the amount of and reason for transfers between Level 1 and Level 2 of the fair value hierarchy, and adds new disclosure requirements for Level 3 measurements.improve consistent application. This ASU is effective for all entities for fiscal years beginning after December 15, 2019,2020, and interim periods within those fiscal years. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective, or prospective basis. The Company adopted the standard on January 1, 2021 on a prospective basis, which did not have an impact on our disclosures for income taxes.

61


In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which introduced an expected credit loss methodology for the measurement and recognition of credit losses on most financial assets, including trade accounts receivables. The expected credit loss methodology under ASU 2016-13 is based on historical experience, current conditions and reasonable and supportable forecasts, and replaces the probable/incurred loss model for measuring and recognizing expected losses under current GAAP. The ASU also requires disclosure of information regarding how a company developed its allowance, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes. The ASU and its related clarifying updates are effective for smaller reporting companies for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. Certain disclosures per this ASU are required to be appliedpermitted.

The Company adopted the standard on a retrospective basis and othersJanuary 1, 2021 on a prospective basis.basis, utilizing the transition method that allows recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company is currently assessingCompany's financial results for reporting periods beginning on or after January 1, 2021 are presented under the new standard, while financial results for prior periods continue to be reported in accordance with the prior standard and the Company's historical accounting policy. The net cumulative effect due to the adoption of the new standard did not impact retained earnings as of January 1, 2021. Although the adoption of the new standard did not have a material impact on the Company's consolidated financial statements at the date of adoption, expected credit losses could change as a result of changes to credit loss experience, specific risk characteristics of the Company's portfolio of financial assets or management’s expectations of future economic conditions that affect the collectability of the Company's financial assets. Management continues to periodically assess these factors and incorporates any changes will have onin its disclosure requirements for fair value measurement.estimate of credit losses.


Recently Issued Accounting Standards Not Yet Adopted

Management has evaluated other recently issued accounting pronouncements and does not believe that they will have a significant impact on the Company's consolidated financial statements and related disclosures.

Note 2. Merger, Acquisitions and Discontinued Operations

Merger and Recapitalization

The Merger, as described in Note 1. Business, Basis of Presentation and Significant Accounting Policies, has been accounted for as    During March 2020, the World Health Organization declared a reverse recapitalization in accordance with GAAP. As such, IEA Services is treated as the continuing company and M III is treated as the ‘‘acquired’’ company for financial reporting purposes. This determination was primarily based on IEA Services’ operations comprising substantially all of the ongoing operations of the post-combination company, M III directors not constituting a majority of the Board of the post-combination company, IEA Services’ senior management comprising substantially all of the senior management of the post-combination company and the Seller holding a 48.3% voting interest in the Company, while no single M III shareholder holds more than a 20% voting interest. Accordingly, for accounting purposes, the Merger is treated as the equivalent of IEA Services issuing stock for the net assets of M III, accompanied by a recapitalization. The net assets of M III are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Merger are the historical operations of IEA Services.

The amount of merger consideration paid at the Closing Date to IEA (the “Merger Consideration”) was $81.4 million in cash, and 10,428,500 shares of common stock and 34,965 shares of Series A convertible preferred stock with an aggregate stated value of $126.3 million at the Closing Date. Immediately following the closing, the Seller owned approximately 48.3% of the Company’s common stock and other stockholders owned approximately 51.7% of the Company’s outstanding common stock. The Merger Consideration was subject to adjustment based on final determinations of IEA Services’ closing date working capital and indebtedness, which determination was finalized approximately 45 days after the Closing Date with minimal impact to the Merger Consideration as calculated on the Closing Date of the Merger.

Pursuant to the Merger Agreement, the Company is required to issue to the Seller up to an additional 9,000,000 common shares in the aggregate based upon satisfaction of financial targets for 2018 and 2019. See Note 8. Fair Value of Financial Instruments for further discussion.

Acquisitions

CCS

On September 25, 2018, IEA Services acquired CCS for $106.6 million in cash. The Company financed this acquisition through borrowings on its new credit facility as discussed in Note 9. Debt.

The wholly-owned subsidiaries of CCS, Saiia and the ACC Companies, generally enter into long-term contracts with both government and non-government customers to provide EPC services for environmental, heavy civil and mining projects. As discussed in Note 1. Business, Basis of Presentation and Significant Accounting Policies, this acquisition is being accounted for as a business combination under the acquisition method of accounting.

William Charles

On November 2, 2018, IEA Services acquired William Charles for $77.7 million, consisting of $73.2 million in cash and $4.5 million of the Company's common stock (477,621 common shares at $9.45 share price). The Company financed the cash portion of this acquisition through borrowings on its new credit facility as discussed in Note 9. Debt.

William Charles generally enters into long-term contracts with both government and non-government customers to provide EPC services for rail civil infrastructure, environmental and heavy civil projects. As discussed in Note 1. Business, Basis of Presentation and Significant Accounting Policies, this acquisition is being accounted for as a business combination under the acquisition method of accounting.

See Note 6. Goodwill and Intangible Assets, Net for disclosure of the weighted average amortization period for each major class of acquired intangible asset.
(3) The Company's consolidated deferred income taxes are presented as a net deferred tax asset (long-term) in the consolidated balance sheet as of December 31, 2018.

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the acquisitions of CCS and William Charles isglobal pandemic related to the expected,rapidly growing outbreak of a novel strain of coronavirus (“COVID-19”). The COVID-19 pandemic has significantly affected economic conditions in the United States and internationally as national, state and local governments reacted to the public health crisis by requiring mitigation measures that have disrupted business activities for an uncertain period of time.

The Company incurred $1.3 million and $3.0 million of specific synergies and other benefits that the Company believes will result from combining the operations of CCS and William Charles with the operations of IEA. This goodwill isexpenses related to the Company's single reportable segment and is deductible for income tax purposes, with the exception of $4.5 million for CCS that is not deductible.

Acquisition-related costs incurred by the Company for the acquisitions of CCS and William Charles were $6.6 million and $7.6 million, respectively,COVID-19 pandemic for the year ended December 31, 2018,2021 and 2020, respectively. Currently, most of the Company’s construction services are included within selling, generaldeemed essential under governmental mitigation orders and administrative expensesall of our business segments continue to operate. The Company has issued several notices of force majeure for the purpose of recognizing delays in construction schedules due to COVID-19 outbreaks on certain of its work sites and has also received notices of force majeure from the owners of certain projects and certain subcontractors. Management does not believe that any delays on projects related to these events of force majeure will have a material impact on the
Company's results of operations.

Management’s top priority has been to take appropriate actions to protect the health and safety of the Company's employees, customers and business partners, including adjusting the Company's standard operating procedures to respond to evolving health guidelines. Management believes that it is taking appropriate steps to mitigate any potential impact to the Company; however, given the uncertainty regarding the potential effects of the COVID-19 pandemic, any future impacts cannot be quantified or predicted with specificity.

The effects of the COVID-19 pandemic could affect the Company’s future business activities and financial results, including new contract awards, reduced crew productivity, contract amendments or cancellations, higher operating costs or delayed project start dates or project shutdowns that may be requested or mandated by governmental authorities or others.

Note 2. Contract Assets and Liabilities

We bill our customers based on contractual terms, including, milestone billings based on the completion of certain phases of the work. Sometimes, billing occurs after revenue recognition, resulting in unbilled revenue, which is accounted for as a contract asset. Sometimes we receive advance mobilization payments from our customers before revenue is recognized, resulting in deferred revenue, which is accounted for as a contract liability.

The amounts in the supplemental unaudited pro forma results apply the Company's accounting policies and reflect certain adjustments to, among other things, (i) exclude the impact of transaction costs incurred in connection with the acquisitions, (ii) include additional depreciation and amortization that would have been charged assuming the same fair value adjustments to property, plant and equipment and acquired intangibles had been applied on January 1, 2017 and (iii) include additional interest expense that would have been charged assuming the incremental borrowings the Company incurred to finance the acquisitions had been outstanding on January 1, 2017. Accordingly, these supplemental unaudited pro forma results have been prepared for comparative purposes only and are not intended to be indicative of the results of operations that would have occurred had the acquisitions actually occurred in the prior year period or indicative of the results of operations for any future period.

Discontinued Operations
As a result of significant, historical operating losses incurred for the Company's Canadian solar operations, management made the decision to abandon its operations in Canada and to refocus the business on the U.S. wind energy market. The Company completely abandoned the Canadian solar operations of H.B. White, effectively completed all significant projects in Canada and reduced or redeployed substantially all of its Canadian resources, facilities and equipment as of July 2016. Accordingly, the operating results of its operations in Canada for the year ended December 31, 2016 have been classified as discontinued operations in the consolidated statement of operations, and the carrying amounts of major classes of assets and liabilities were $0 for H.B. White as of the end of 2016. Interest expense that was specifically identifiable to debt related to supporting the Canadian solar operations of H.B. White qualified as discontinued operations and was allocated to the interest expense component within net income from discontinued operations in the Company’s consolidated statement of operations.

In 2019, the Company entered into three equity agreements and issued Series B Preferred Stock as discussed in Note 7. Debt and Series B Preferred Stock. The agreements required that on the conversion of any of the Convertible Series A Preferred Stock to common shares, the Series B Preferred Stock will receive additional warrants (Anti-dilution Warrants) to purchase common shares at a price of $0.0001 per share. The agreements also required that if the Company fails to meet a certain Adjusted EBITDA (as that term is defined in the agreements) threshold on a trailing twelve-month basis from May 31, 2020 through April 30, 2021, the Series B Preferred Stock will receive additional warrants (Performance Warrants) to purchase common shares at $0.0001 per share.

On August 2, 2021, the Company closed an underwritten public offering. At the closing of the offering, the following equity transactions were completed with ASOF Holdings I, L.P. (“ASOF”) and Ares Special Situations Fund IV, L.P. (“ASSF” and, together with ASOF, “Ares Parties”):

the Ares Parties converted all of their Series A Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”) (consisting of all of the Company's issued and outstanding shares of Series A Preferred Stock), into 2,132,273 shares of common stock;

the Company issued to the Ares Parties 507,417 shares of common stock representing shares of common stock underlying warrants that the Ares Parties were entitled to pursuant to anti-dilution rights that are triggered upon conversion of the Series A Preferred Stock described below as a part of the “Series B Preferred Stock - Anti-Dilution Warrants” section;

For further discussion of the equity transaction see Note 9. Earnings Per Share.

The information below describes the balance sheet classification and the recurring fair value measurement for these requirements:

Private Warrants (recurring)

The Company has 295,000 private warrants that are not actively traded on the public markets and the Company adjusts the fair value at the end of each fiscal period using the price on that date multiplied by the remaining private warrants. The Private warrants were recorded as warrant obligations and the fair value adjustment was recorded as Warrant liability fair value adjustment. For further discussion see Note 9. Earnings Per Share.
Series B Preferred Stock - Anti-dilution Warrants (recurring)

The number of common shares attributable to the warrants issued to Series B Preferred Stockholders for anti-dilution warrants were determined as follows;

upon conversion by Series A Preferred Stockholders and determined on a 30-day volume weighted average. As noted above, these anti-dilution warrants were issued upon the conversion of the Series A Preferred Stock as part of the equity transaction on August 2, 2021 and therefore no changesliability was recorded at December 31, 2021.

upon the exercise of any warrant with an exercise price of $11.50 or higher. As of December 31, 2021, the Company had 3,827,325 Merger Warrants to purchase shares of common stock at $11.50 per share. If the Merger Warrants were converted it would result in an additional 1.2 million anti-dilution warrants being issued. As of December 31, 2021, the Company recorded the anti-dilution warrants at fair value, which was estimated using a Monte Carlo simulation based on certain significant unobservable inputs, such balancesas a risk rate premium, volatility of stock, conversion stock price, current stock price and amount of time remaining before expiration of the Merger Warrants. The calculation derived a fair value of $5.6 million for the year ended liability based on an anti-dilution warrant fair value of $4.77.

Significant unobservable inputs used in the fair value calculation as of the periods indicated were as follows:

Stock price$9.20 
Conversion stock price$11.50 
Time before Merger Warrant expiration1.23 
Stock volatility63.77 %
Risk-free interest rate0.47 %

Series B-1 Preferred Stock - Performance Warrants (recurring)

The warrant liability was recorded at fair value as a liability, using a Monte Carlo Simulation based on certain significant unobservable inputs, such as a risk rate premium, Adjusted EBITDA volatility, stock price volatility and projected
Adjusted EBITDA for the Company. The Company remained above the Adjusted EBITDA threshold for the trailing twelve-month basis from May 31, 2017.2020 through April 30, 2021 and therefore was not required to issue additional warrants.

See further discussion on Series B-3 Preferred - Closing Warrants in Note 7. Debt and Series B Preferred Stock.

Rights Offering

The Company conducted a rights offering in connection with the offering of the Series B Preferred Stock. The rights offering fair value was recorded as a liability and was a deemed dividend to common stockholders. On March 4, 2020 we completed the rights offering and removed the liability associated with the fair value.

Contingent Consideration

Pursuant to the merger agreement with M III, the Company was required to issue up to an additional 9,000,000 shares of common stock, if the 2018 and 2019 adjusted EBITDA targets were achieved. The Company did not achieve the Adjusted EBITDA targets which resulted in fair value adjustments to the contingent liability.
Other financial instruments of the Company not listed in the table above primarily consist of cash and cash equivalents, accounts receivable, accounts payable and other current liabilities that approximate their fair values, based on the nature and short maturity of these instruments, and they are presented in the Company's consolidated balance sheets at carrying cost. Additionally, management believes that the carrying value of the Company's outstanding debt balances, further discussed in Note 9.7. Debt and Series B Preferred Stock, approximate fair value due to their floating interest rates.value.

Contingent Consideration

Pursuant to the Merger Agreement, the Company shall issue to the Seller up to an additional 9,000,000 common shares in the aggregate, which shall be fully earned if the final 2018 and 2019 financial targets are achieved. The Company may be required to issue such shares if the 2019 financial target is achieved. As of December 31, 2018, the Company recorded the contingent consideration liability at fair value, which was estimated using a Monte Carlo simulation based on certain significant unobservable inputs, such as a risk rate premium, peer group EBITDA volatility, stock price volatility and projected Adjusted EBITDA for the Company for 2019. The calculation derived a fair value adjustment of $46.3 million to the liability based on 2018 actual financial results and the expected probability of reaching the full amount of contingent consideration in 2019.

Senior Unsecured Notes
Old Credit Facility

On August 17, 2021, IEA Energy Services LLC, a wholly owned subsidiary of the Company (“Services”), issued $300.0 million aggregate principal amount of its 6.625% senior unsecured notes due 2029 (the “Senior Unsecured Notes”), in a private placement. Interest is payable on the Senior Unsecured Notes on each February 15 and August 15, commencing on February 15, 2022. The Senior Unsecured Notes will mature on August 15, 2029. The Senior Unsecured Notes are guaranteed on a senior unsecured basis by the Company and certain of its domestic wholly-owned subsidiaries (the “Guarantors”).

On or after August 15, 2024, the Senior Unsecured Notes are subject to redemption at any time and from time to time at the option of Services, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if redeemed during the twelve-month period beginning on August 15 of the years indicated below:

YearPercentage
2024103.3 %
2025101.7 %
2026 and thereafter100.0 %

Prior to August 15, 2024, Services may also redeem some or all of the Senior Unsecured Notes at the principal amount of the Senior Unsecured Notes, plus a “make-whole premium,” together with accrued and unpaid interest. In addition, at any time prior to August 15, 2024, Services may redeem up to 40.0% of the original principal amount of the Senior Unsecured Notes with the proceeds of certain equity offerings at a redemption price of 106.63% of the principal amount of the Senior Unsecured Notes, together with accrued and unpaid interest.

In connection with the closingissuance of the Merger in March 2018, the outstanding borrowings under IEA Services' then-existing line of credit of $38.4 million were repaid using proceeds from the Merger credit facility described below, and the old credit facility was terminated. The amount outstanding as of December 31, 2017 of 33.7 million is presented as line of credit - short-term in the consolidated balance sheet as these borrowings contractually matured on December 31, 2018. The weighted average interest rate on revolving loans outstanding under this facility as of December 31, 2017 was 4.50%.

Merger Credit Facility

In conjunction with the completion of the Merger, IEA Services refinanced its prior credit facility with a new facility that provided for aggregate revolving borrowings of up to $50.0 million and a $50.0 million delayed draw term loan facility. Upon closing of the acquisition of CCS in September 2018, the outstanding borrowings under this Merger credit facility of $53.5 million were repaid, plus accrued and unpaid interest, using proceeds from the new credit facility described below, and the Merger credit facility was terminated. The Company recognized a $1.8 million loss on extinguishment of debt upon this termination, primarily due to the write-off of the unamortized debt issuance costs and discount for this facility as of such date, which is reflected within other expense in the consolidated statement of operations for the year ended December 31, 2018.

Acquisition Credit Facility

At closing of the CCS acquisition, IEASenior Unsecured Notes, Services entered into a credit agreement for a new credit facility, which was amended and restated in connectionan indenture (the “Indenture”) with the closingGuarantors and Wilmington Trust, National Association, as trustee, providing for the issuance of the William Charles acquisition, and was further amended and restated on November 16, 2018 (as amended and restated, the “A&R Credit Agreement”). The A&R Credit Agreement provides for a term loan facility of $300.0 million and a revolving line of credit of $50.0 million, which is available for revolving loans and letters of credit. Availability on the line of credit is subject to customary borrowing base calculations.

On September 25, 2018, $200.0 million was drawn on the term loan facility and $20.5 million was drawn on the line of credit to pay the CCS acquisition consideration, repay borrowings under the Merger credit facility and repay certain assumed indebtedness of Saiia and the ACC Companies. The remaining $100.0 million was drawn on the term loan facility on


November 2, 2018 to pay the cash portion of the William Charles acquisition consideration and to repay certain assumed indebtedness of William Charles, and an additional $26.0 million of revolving loans were drawn in the third and fourth quarter of 2018, to be used for working capital and other general corporate purposes, for total outstanding revolving loans of $46.5 million as of December 31, 2018. The Company capitalized $24.5 million of financing fees that were incurred to obtain this new credit facility.

Term loan borrowings mature on September 25, 2024 and are subject to quarterly amortization of principal, commencing on the last day of the first quarter of 2019, in an amount equal to 2.50% of the aggregate principal amount of such loans. Beginning with 2020, an additional annual payment is required equal to 75% of Excess Cash Flow (as defined in the A&R Credit Agreement) for the preceding fiscal year if such Excess Cash Flow is greater than $2.5 million, with the percentage of Excess Cash Flow subject to reduction based upon the Company’s consolidated leverage ratio. Borrowings under the revolving line of credit mature on September 25, 2023.

Interest on term loan borrowings accrues at an interest rate of, at the Company's option, (x) LIBOR plus a margin of 6.25% or (y) the applicable base rate plus a margin of 5.25%. Interest on revolving loans accrues at an interest rate of, at the Company's option, (x) LIBOR plus a margin of 4.25% or (y) the applicable base rate plus a margin of 3.25%. The weighted average interest rate on borrowings under this credit facility as of December 31, 2018 was 8.82%.

Obligations under this credit facility are guaranteed by Infrastructure and Energy Alternatives, Inc., Holdings and each existing and future, direct and indirect, wholly-owned, material domestic subsidiary of Infrastructure and Energy Alternatives, Inc. other than IEA Services (together with IEA Services, the “Credit Parties”), and are secured by all of the present and future assets of the Credit Parties, subject to customary carve-outs.

Letters of Credit and Surety Bonds

In the ordinary course of business, the Company is required to post letters of credit and surety bonds to customers in support of performance under certain contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit or surety bond commits the issuer to pay specified amounts to the holder of the letter of credit or surety bond under certain conditions. If the letter of credit or surety bond issuer were required to pay any amount to a holder, the Company would be required to reimburse the issuer, which, depending upon the circumstances, could result in a charge to earnings. As of December 31, 2018 and 2017, the Company was contingently liable under letters of credit issued under its respective revolving lines of credit in the amount of $3.0 million and $5.9 million, respectively, related to projects. In addition, as of December 31, 2018 and 2017, the Company had outstanding surety bonds on projects of $1.68 billion and $535.5 million, respectively, which includes the bonding line of the acquired ACC Companies, Saiia and William Charles as of the 2018 date.

Note 10.8. Commitments and Contingencies


Capital    In the ordinary course of business, the Company enters into agreements that provide financing for machinery and equipment and for other of its facility, vehicle and equipment needs. The Company reviews all arrangements for potential leases, and at inception, determines whether a lease is an operating or finance lease. Lease assets and liabilities, which generally represent the present value of future minimum lease payments over the term of the lease, are recognized as of the commencement date. Under ASC Topic 842, leases with an initial lease term of twelve months or less are classified as short-term leases and are not recognized in the consolidated balance sheets unless the lease contains a purchase option that is reasonably certain to be exercised.
    Lease term, discount rate, variable lease costs and future minimum lease payment determinations require the use of judgment, and are based on the facts and circumstances related to the specific lease. Lease terms are generally based on their initial non-cancelable terms, unless there is a renewal option that is reasonably certain to be exercised. Various factors, including economic incentives, intent, past history and business need are considered to determine if a renewal option is reasonably certain to be exercised. The implicit rate in a lease agreement is used when it can be determined. Otherwise, the incremental borrowing rate, which is based on information available as of the lease commencement date, including applicable lease terms and the current economic environment, is used to determine the value of the lease obligation.
Finance Leases

The Company has obligations, exclusive of associated interest, recognized under various capitalfinance leases for equipment totaling $63.5$54.4 million and $20.6$57.6 million at December 31, 20182021 and 2017,2020, respectively. Gross amounts recognized within property, plant and equipment net in the consolidated balance sheets under these capitalfinance lease agreements at December 31, 20182021 and 20172020 totaled $76.9$143.6 million and $27.0$128.0 million, less accumulated depreciation of $10.1$71.4 million and $2.8$55.1 million, respectively, for net balances of $66.8$72.2 million and $24.2 million.$72.9 million, respectively. Depreciation of assets held under the capitalfinance leases is included within cost of revenue in the consolidated statements of operations.

Letters of Credit and Surety Bonds

    In the ordinary course of business, the Company may be required to post letters of credit and surety bonds to customers in support of performance under certain contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit or surety bond commits the issuer to pay specified amounts to the holder of the letter of credit or surety bond under certain conditions. If the letter of credit or surety bond issuer were required to pay any amount to a holder, the Company would be required to reimburse the issuer, which, depending upon the circumstances, could result in a charge to earnings. As of December 31, 2021 and 2020, the Company was contingently liable under letters of credit issued under its respective revolving lines of credit in the amount of $31.1 million and $7.8 million, respectively, related to construction projects and insurance. In addition, as of December 31, 2021 and 2020, we had outstanding surety bonds on projects with nominal amounts of $3.3 billion and $2.8 billion, respectively. The remaining approximate exposure related to these surety bonds amounted to approximately $353.5 million and $293.1 million, respectively. We anticipate that our current bonding capacity will be sufficient for the next twelve months based on current backlog and available capacity.

Deferred Compensation


The Company has two2 deferred compensation plans. The first plan is a supplemental executive retirement plan established in 1993 that covers four4 specific employees or former employees, whose deferred compensation is determined by the number of service years. Payment of the benefits is to be made for 20 years after employment ends. TwoNaN former employees are currently receiving benefits, and two participants are1 participant is still employeesan employee of the Company. The two1 current employees have bothemployee has reached the full benefit level, and as a result, the present value of the liability is estimated using the normal retirement method. Payments under this plan for 20182021 were $0.1$0.2 million. Maximum aggregate payments per year if all participants were retired would be $0.3 million. As of December 31, 20182021 and 2017,2020, the Company had a long-term liability of $3.2$3.3 million and $3.3$3.5 million, respectively, for the supplemental executive retirement plan.


The Company offers a non-qualified deferred compensation plan which is made up of an executive excess plan and an incentive bonus plan. This plan was designed and implemented to enhance employee savings and retirement accumulation on a tax-advantaged basis, beyond the limits of traditional qualified retirement plans. This plan allows employees to: (i) defer annual
73


compensation from multiple sources; (ii) create wealth through tax-deferred investments; (iii) save and invest on a pretax basis to meet accumulation and retirement planning needs; and (iv) utilize a diverse choice of investment options to maximize returns. Executive awards are expensed when vested. Project Management Incentive Payments are expensed when awarded as they are earned through the course of the performance of the project to which they are related. Other incentive payments are expensed when vested as they are considered to be earned by retention. Unrecognized compensation expense for the non-qualified deferred compensation plan at December 31, 2018, 20172021, 2020 and 20162019 was $2.2$3.0 million, $1.3$1.7 million and $0.2$1.5 million, respectively. As of December 31, 20182021 and 2017,2020, the Company had a long-term liability of $3.0$3.3 million and $1.7$4.2 million, respectively, for deferred compensation to certain current and former employees.

Carlitos Lopez v. Chicago Transit Authority, Parsons Brinkerhoff, Inc. and, Ragnar Benson, LLC.A lawsuit was filed on January 11, 2019 in the Circuit Court of Cook County, Illinois, alleging claims for personal injury and premises liability arising out of an accident the plaintiff sustained during a construction project. The case was originally filed on March 10, 2014 in the Circuit Court of Cook County, Illinois, subsequently voluntarily dismissed by the plaintiff, and refiled. The plaintiff seeks an unspecified amount of damages in the refiled case. This case is currently in the filing stage. The Company continues to vigorously defend itself; however,deductible, which the Company cannot predicthas exhausted. Pursuant to agreements entered into in connection with the outcomesale of this action. TheSeries B Preferred Stock, the Company believes it is coveredobligated to indemnify Oaktree and Ares for any legal fees and damages incurred by insurance foreither of them in connection with this matter.


In addition to the foregoing, theThe Company is involved in a variety of other legal cases, claims and other disputes that arise from time to time in the ordinary course of its business. TheWhile the Company believes it has good defense against these cases and intends to defend them vigorously, it cannot provide assurance that it will be successful in recovering all or any of the potential damages it has claimed or in defending claims against the Company. While the lawsuits and claims are asserted for amounts that may be material, should an unfavorable outcome occur, management does not currently expect that any currently pending matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows. However, an unfavorable
resolution of one or more of such matters could have a material adverse effect on the Company's business, financial condition, results of operations and cash flows.


Note 11.9. Earnings (Loss) Per Share


The Company calculates basic earnings (loss) per share (“EPS”) in accordance with ASC 260, Earnings per Share. Basic EPS is computed by dividing income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period.


Income (loss) available to common stockholders is computed by deducting the dividends accumulated for the period on cumulative preferred stock from net income. If there is a net loss, the amount of the loss is increased by those preferred dividends. The contingent consideration fair value adjustment is a mark-to-market adjustment based on the Company not reaching the required financial targets; see Note. 6 Fair Value of Financial Instruments for further discussion. The Company is required to reverse the mark-to-market adjustment from the numerator as shown below.


Diluted EPS, where applicable, assumes the dilutive effect of (i) contingently issuable earn-out shares, (ii) Series A cumulative convertible preferred stock, using the if-converted method, (ii) publicly traded warrants, (iii) Series B Preferred Stock - Warrants and (iii)(iv) the assumed exercise of in-the-money stock options and warrants and the assumed vesting of outstanding RSUs,restricted stock units (“RSUs”), using the treasury stock method.


Whether the Company has net income or a net loss determines whether potential issuances of common stock are included in the diluted EPS computation or whether they would be anti-dilutive. As a result, if there is a net loss, diluted EPS is computed in the same manner as basic EPS is computed. Similarly, if the Company has net income but its preferred dividend adjustment made in computing income available to common stockholders results in a net loss available to common stockholders, diluted EPS would be computed in the same manner as basic EPS.

The Company has a policy of issuingplans to issue new common shares to satisfy the exercise of Options. As of December 31, 2018,2021, there was $3.1$0.1 million of unrecognized stock-based compensation expense for unvested Options, and the expected remaining expense period was 3.250.25 years.

The weighted average grant-date fair value per share of Options granted in 2018 was $10.37. The Company estimated the fair value of Options issued using the Black-Scholes option pricing model. Expected volatilities were based on the historical volatility of the Company’s stock, peer group and other factors. The Company used historical data to estimate Option exercises and employee terminations within the valuation model. Dividends were based on an estimated dividend yield. The risk-free interest rates used for the periods within the contractual life of the Options were based on the U.S. Treasury rates in effect at the time of the grant. Option valuation models require the input of subjective assumptions including the expected volatility and lives.

The following assumptions were used to value Option grants during 2018:

The Company assesses the realizability of the deferred tax assets at each balance sheet date based on actual and forecasted operating results in order to determine the proper amount, if any, required for a valuation allowance. As of December 31, 2021, the Company has a Canadian net operating loss carryover of $93.9 million and net operating loss carryovers which will begin to expire in 2035. Since the Canadian operations are in a cumulative loss position and the operations have ceased, the Company has recorded a full valuation allowance related to the Canadian net operating losses.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income and tax-planning strategies in making this assessment. ItThe Company believes ownership changes have occurred in the past. This may impact the Company's ability to utilize portions of its net operating losses and interest carry forward in future periods. However, it is management’s belief that it is more likely than not that the net deferred tax assets related to the Company will be utilized prior to expiration.


As of December 31, 2018,2021, the Company hadhas a federal net operating loss carryover of $40.1$11.0 million and net operating loss carryovers in certain state tax jurisdictions of approximately $45.6 million, which may be applied against future taxable income. $10.5 million of the$44.0 million. The federal net operating loss carryover was incurred prior toin 2018 and will begin to expire in 2035.2019 and can be carried forward indefinitely. The state net operating loss carryovers will begin to expire in 2025. As of December 31, 2018, the Company had total alternative minimum tax credit carryovers of approximately $1.1 million.


The Company files income tax returns in U.S. federal, state and certain international jurisdictions. For federal and certain state income tax purposes, the Company’s 2015Company's 2017 through 20172021 tax years remain open for examination by the tax authorities under the normal statute of limitations. For certain international income tax purposes, the Company’s 2014tax years 2015 through 2017 tax years2021 remain open for examination by the tax authorities under the normal statute of limitations.

The Company classifies interest expense and penalties related to unrecognized tax benefits as components of the income tax provision. There were no such interest or penalties recognized in the consolidated statements of operations for the years ended December 31, 2018, 20172021, 2020 and 2016,2019, and there were no corresponding accruals as of December 31, 20182021 and 2017. As of2020.

Deferred Taxes - COVID-19

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted by the U.S. Government in response to the COVID-19 pandemic to provide employment retention incentives. The CARES Act includes many measures to assist companies, including temporary changes to income and non-income-based tax laws. We do not believe that these relief measures materially affect the consolidated financial statements for the year ended December 31, 2021 but some of the key income tax-related provisions of the CARES Act include:

Eliminating the 80% of taxable income limitation by allowing corporate entities to fully utilize net operating losses (“NOLs”) to offset taxable income in 2018, 2019 or 2020.

Allowing NOLs originating in 2018, 2019 or 2020 to be carried back five years.

Increasing the net interest expense deduction limit to 50% of adjusted taxable income beginning 1 January 2019 and 2017,2020.

Allowing taxpayers with alternative minimum tax (“AMT”) credits to claim a refund in 2020 for the entire amount of the credit instead of recovering the credit through refunds over a period of years, as originally enacted by the Tax Cuts and Jobs Act (“TCJA”).

Payroll tax deferral.

The new NOL carryforward and interest expense deduction rules could defer future cash tax liabilities. IEA filed an election to refund $0.5 million AMT credit which was received in the third quarter of 2020.

The Company had not identified any uncertainhas also made use of the payroll deferral provision to defer the 6.2% social security tax, positions for which recognitionis approximately $13.6 million through December 31, 2020. This amount was required.paid at 50% on December 31, 2021. The remaining 50% is required to be paid on December 31, 2022.




Note 14.12. Employee Benefit Plans


The Company participates in numerous multi-employer pension plans (“MEPPs”) that provide retirement benefits to certain union employees in accordance with various collective bargaining agreements (“CBAs”). As of December 31, 2018, 20172021, 2020 and 2016, 26%2019, 25%, 25%24% and 25%27%, respectively, of the Company’s employees were members of collective bargaining units.a CBA. As one of many participating employers in these MEPPs, the Company is responsible, with the other participating employers, for any plan underfunding. Contributions to a particular MEPP are established by the applicable collective bargaining agreements;CBA; however, required contributions may increase based on the funded status of a MEPP and legal requirements of the Pension Protection Act of 2006, which requires substantially underfunded MEPPs to implement a funding improvement plan (“FIP”) or a rehabilitation plan (“RP”) to improve their funded status. Factors that could impact the funded status of a MEPP include investment performance, changes in the participant demographics, declinechange in the number of contributing employers, changes in actuarial assumptions and the utilization of extended amortization provisions. If a contributing employer stops contributing to a MEPP, the unfunded obligations of the MEPP may be borne by the remaining contributing employers. Assets contributed to an individual MEPP are pooled with contributions made by other contributing employers; the pooled assets will be used to provide benefits to the Company’s employees and the employees of the other contributing employers.


An FIP or RP requires a particular MEPP to adopt measures to correct its underfunding status. These measures may include, but are not limited to: (a) an increase in the contribution rate as a signatory to the applicable collective bargaining agreement, (b) a reallocation of the contributions already being made by participating employers for various benefits to individuals participating in the MEPP and/or (c) a reduction in the benefits to be paid to future and/or current retirees. In addition, the Pension Protection Act of 2006 requires that a 5% surcharge be levied on employer contributions for the first year commencing shortly after the date the employer receives notice that the MEPP is in critical status and a 10% surcharge on each succeeding year until a collective bargaining agreementCBA is in place with terms and conditions consistent with the RP. The zone status included in the table below is based on information that the Company received from the plan and is certified by the plan’s actuary. Among other
81


factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are greater than 65% and less than 80% funded, and plans in the green zone are at least 80% funded.


The Company could also be obligated to make payments to MEPPs if the Company either ceases to have an obligation to contribute to the MEPP or significantly reduces its contributions to the MEPP because of a reduction in the number of employees who are covered by the relevant MEPP for various reasons. Due to uncertainty regarding future factors that could trigger a withdrawal liability, as well as the absence of specific information regarding the MEPP’s current financial situation, the Company is unable to determine (a) the amount and timing of any future withdrawal liability, if any, and (b) whether participation in these MEPPs could have a material adverse impact on the Company’s financial condition, results of operations or cash flows.


    The Company contributed $53.5 million to various MEPPs in 2021. The nature and diversity of the Company’s business may result in volatility of the amount of contributions to a particular MEPP for any given period. That is because, inIn any given market, the Company could be working on a significant project and/or projects, which could result in an increase in its direct labor force and a corresponding increase in its contributions to the MEPP(s) dictated by the applicable collective bargaining agreement.CBA. When the particular project(s) finishes and is not replaced, the level of direct labor of contributions to a particular MEPP could also be affected by the terms of the collective bargaining agreement,applicable CBA, which could require at a particular time, an increase in the contribution rate and/or surcharges.

The following tables list the MEPPs the Company considered individually significant in 2018, 2017 and 2016. The Company considers individually significant to be any plan over 5% of its total contributions to all MEPPs for that year. For the years ended December 31, 2018, 2017 and 2016, these plans represented 63%, 54% and 65% of total dollars contributed by the Company, respectively, and six of 55, four of 52 and seven of 22 total plans contributed to by the Company. All of the Company's contributions were less than 5% of the total plan contributions contributed byfrom all participating employers. This information was obtained from

The Company also has a 401(k) plan for non-union employees. Employees are eligible to participate in the plan beginning on their employment date. The Company matches employee contributions up to 4% of employee compensation.

Note 13. Segments

    We operate our business as two reportable segments: the Renewables segment and the Specialty Civil segment. Each of our reportable segments is comprised of similar business units that specialize in services unique to the respective plans’ Form 5500markets that each segment serves. The classification of revenue and gross profit for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses, were made based on segment revenue.

    Separate measures of the Company’s assets, including capital expenditures and cash flows by reportable segment are not produced or utilized by management to evaluate segment performance. A substantial portion of the Company’s fixed assets are owned by and accounted for in our equipment department, including operating machinery, equipment and vehicles, as well as office equipment, buildings and leasehold improvements, and are used on an interchangeable basis across our reportable segments. As such, for reporting purposes, total under/over absorption of equipment expenses consisting primarily of depreciation is allocated to the Company's two reportable segments based on segment revenue.

ITEM 9A. CONTROLS AND PROCEDURES


Disclosure Controls and Procedures


The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.


As of December 31, 2018,2021, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based on that evaluation, the Company’s management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2018.2021.


Management’s Annual Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. 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 GAAP and 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 GAAP, 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.


Management has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2018,2021, utilizing the criteria in the Committee of Sponsoring Organizations of the Treadway Commission’s Internal Control-Integrated Framework (2013). Based on its assessment, our management concluded the Company’s internal control over financial reporting was effective as of December 31, 2018.2021.


Attestation Report of the Independent Registered Public Accounting Firm


This Annual Report on Form 10-K does not include an attestation report ofDeloitte & Touche LLP, our independent registered public accounting firm (PCAOB ID: 34), which audited and reported on the consolidated financial statements included in this Annual Report, has also audited the effectiveness of our internal control over financial reporting because Section 103as December 30, 2021, as stated in its report appearing in Item 8 of the JOBS Act provides that an emerging growth company is not required to provide an auditor's report on internal control over financial reporting for as long as we qualify as an emerging growth company.Part II of this Annual Report.

Remediation of Prior Material Weakness
As of December 31, 2018, management has concluded that the previously disclosed material weaknesses as of December 31, 2017, are remediated based on the following actions taken during the year:
revised our Board and Committee Charters, which now provide appropriate mechanisms through which to demonstrate that effective oversight over financial reporting processes and internal controls is being properly exercised;
implemented an effective annual process to ensure that all employees, as well as members of the Board, and outsourced service providers confirm their compliance with the Company’s Code of Business Conduct;
implemented a whistleblower hotline which is available throughout the organization and through an external website and communicated information regarding the whistleblower hotline to all employees; and
increased communication and training to all employees and the Board regarding the Company’s ethical values and the requirement to comply with laws, rules, regulations, and the Company’s policies, including our Code of Conduct and Ethics.

revised our organizational structure by hiring dedicated key employees, including senior management, with assigned responsibility and accountability for financial reporting processes and internal controls. Further, we will continue to provide ongoing GAAP and internal controls training for all the employees;

implemented an annual financial control risk assessment process as well as a regularly recurring fraud risk assessment process focused on identifying and analyzing risks of financial misstatement due to error and/or fraud, including management override of controls;

hired another big four accounting firm as an internal controls resource, to create and develop a risk based internal controls plan. We are also enhancing the business process documentation and management's self-assessment and testing for internal controls;

enhanced the information technology control framework to support all business applications and infrastructure.

enhanced the management review controls over the application of GAAP and accounting measurements for significant accounts and transactions by adding resources with the required skills and assigned responsibility and accountability for performing an effective review; and

management review controls have been reassessed to provide the appropriate level of precision required to mitigate the potential for a material misstatement. In addition, we have enhanced the design and implementation of and supporting documentation over management review controls to make clear: (i) management’s expectations related to transactions that are subject to such controls; (ii) the level of precision and criteria used for investigation; and (iii) evidence that all outliers or exceptions that should have been identified are investigated and resolved.



These actions resulted in improved control environment which enhanced review procedures and improved documentation standards which were in place for a period of time in 2018 that was sufficiently long enough for our management to conclude, through testing that the controls are operating effectively.

Internal Control over Financial Reporting for Acquisitions

Management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include an assessment of certain elements of internal controls over financial reporting of CCS and William Charles which were acquired on September 25, 2018 and November 2, 2018, respectively, which is included in the consolidated financial statements of the Company for the year ended December 31, 2018. CCS accounts for 29.3% of total assets and 9.8% of total revenue, while William Charles accounts for 27.4% of total assets and 6.4% of total revenue. See Note. 2 Merger, Acquisition and Divestiture for further discussion.


Changes in Internal Control over Financial Reporting


Other than changes described under Remediation of Prior Material Weaknesses,During the quarter ended December 31, 2021, there washas been no change in our internal control over financial reporting, identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended December 31, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting, expect as described below.reporting.
