PART I

ITEM 1.
BUSINESS
We are a leading infrastructure construction company operating mainly throughout North America across a range of industries. Our primary activities include the engineering, building, installation, maintenance and upgrade of communications, energy, utility and other infrastructure, such as: wireless, wireline/fiber and customer fulfillment activities; petroleum and natural gas pipeline infrastructure; electrical utility transmission and distribution; power generation, including renewables; heavy civil; and industrial infrastructure. Our customers are primarily in these industries. Including our predecessor companies, we have been in business for 90 years. For the twelve month period ended December 31, 2019, we had an average of approximately 21,000 employees and 350 locations. We offer our services primarily under the MasTec service mark. We have been consistently ranked among the top specialty contractors by Engineering News-Record for the past several years.
We provide our services to a diversified base of customers. We often provide services under master service and other service agreements, which are generally multi-year agreements. The remainder of our work is generated pursuant to contracts for specific projects or jobs that require the construction or installation of an entire infrastructure system or specified units within an infrastructure system.
We seek to grow and diversify our business organically and through acquisitions and/or other strategic arrangements in order to deepen our market presence, broaden our geographic reach and expand our service offerings. For discussion of our recent acquisitions, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Business,” which is incorporated by reference.
We manage our operations under five operating segments, which represent our five reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) Power Generation and Industrial and (5) Other. This structure is generally focused on broad end-user markets for our labor-based construction services.
The Communications segment performs engineering, construction, maintenance and customer fulfillment activities related to communications infrastructure, primarily for wireless and wireline/fiber communications and install-to-the-home customers, and, to a lesser extent, infrastructure for utilities, among others. We perform engineering, construction and maintenance services for oil and natural gas pipelines and processing facilities for the energy and utilities industries through our Oil and Gas segment. Our Electrical Transmission segment primarily serves the energy and utility industries through the engineering, construction and maintenance of electrical transmission lines and substations. Our Power Generation and Industrial segment primarily serves energy, utility and other end-markets through the installation and construction of power facilities, including from renewable sources, related electrical transmission infrastructure, ethanol/biofuel facilities and various types of heavy civil and industrial infrastructure. The Other segment includes equity investees, the services of which vary from those provided by our primary segments, as well as other small business units that perform construction and other services for a variety of international end-markets. See Note 13 - Segments and Related Information and Note 14 - Commitments and Contingencies in the notes to the audited consolidated financial statements, which are incorporated by reference, for segment related information and significant customer concentrations.
In this Form 10-K, “$” means U.S. dollars unless otherwise indicated.
Industry Trends
Our industry is composed of national, regional and local companies that provide services to customers in a range of industries. We believe the following industry trends affect demand for our services:
Opportunities in our Communications Segment
Significant advances in technology and rapid innovation in service offerings to data consumers continue to increase demand for faster and more reliable wireless and wireline/fiber communications network services. In its February 2020 Annual Internet Report, 2018-2023, Cisco Systems, Inc. (“Cisco”) predicts that broadband connection speeds in North America will more than double by 2023, from approximately 55 Mbps to over 140 Mbps. As a result of increased usage of mobile devices, combined with advancements in the “Internet of Things (IoT),” the amount of data affecting network traffic is expected to experience significant and accelerating levels of future growth. Increased data usage from video and voice transmission, digital video and music streaming, ‘smart’ television technology, home automation and connected home monitoring offerings, ‘Smart City’ initiatives, artificial intelligence, augmented and virtual reality and other advanced data services, including machine-to-machine connections, such as autonomous vehicles, video surveillance, robotics, drones, ‘smart’ meters and digital health monitors, among others, are expected to significantly increase data traffic, resulting in the need for new and upgraded networks.
In response to these growing demands, communications service providers (“CSPs”) are expanding, densifying and optimizing current wireless and wireline/fiber communications network capacity, while initiating a build-out of 5G infrastructure, the next generation of wireless and fixed wireless network capacity. An August 2019 Gartner, Inc. forecast indicates that to achieve nationwide coverage levels, changes to the structure of the network architecture for 5G wireless communications will require a longer period of installation when compared to past generation changes in wireless infrastructure. In order to maintain performance standards as 5G is built-out, CSPs will need to undertake targeted strategic improvements to their 4G legacy networks by upgrading 4G core infrastructure alongside 5G deployment areas. Cisco, in its Annual Internet Report, predicts that 5G devices and connections will be over 10 percent of global mobile devices and connections by 2023. Large scale 5G deployments, which are expected over the next several years, will include additional and improved tower capacity, as well as deployment of numerous higher bandwidth small/micro cells and distributed antenna systems to densify network performance. In addition, nationwide fiber projects in support of 5G technologies, such as Verizon Communications, Inc.’s (“Verizon”) ‘One Fiber’ program, continue to expand to support network densification, data capacity and speed. Also, AT&T is continuing to build the First Responder Network Authority (“FirstNetTM ”), a new wireless official public safety network created by the federal government for first responders throughout the United States. Further, proposed industry merger activity, which is in the process of final approval and expected to be completed in 2020, will merge two nationwide CSPs, and is expected to result in the creation of a new nationwide CSP.

We believe that the initiation of nationwide 5G tower deployments, deployment of small/micro cells, initiation of fiber projects to support 5G, initial deployment and subsequent capacity additions to FirstNetTM, as well as an expected increase in activity levels for various nationwide CSPs subsequent to expected industry merger activity, will lead to significant increases in 5G telecommunications capital expenditures over multiple years.
One industry publication anticipates that up to an estimated $250 billion will be invested in 5G technologies over the next decade, and another industry publication predicts that the United States will require up to an estimated $150 billion of fiber infrastructure investment over the next five to seven years to support the increases in projected mobile data traffic and related broadband infrastructure needs. Furthermore, in 2018, the Federal Communications Commission (“FCC”) announced an initiative to speed deployment of 5G technology in the U.S. through the Facilitate America’s Superiority in 5G Technology, or “FAST” Plan. The FAST Plan is designed to make more low, mid and high-band spectrum available to the market and encourage additional investment in 5G wireless infrastructure by streamlining regulatory processes and updating infrastructure policies to speed the review of small cell infrastructure. During 2019, the FCC completed its first set of high-band airwaves auctions to make spectrum available for 5G wireless, IoT and other advanced spectrum-based services. Additionally, in 2018, the FCC made additional funds available for the deployment of high-speed broadband technology under the Connect America Fund (“CAF”) program, which was designed to improve the quality and expand the availability of high-speed internet service in rural areas. In addition, in January 2020, the FCC announced its Rural Digital Opportunity Fund, which will push out over $20 billion in funding over the next 10 years to build and connect gigabit broadband speeds in unserved rural areas and is a follow-up initiative to the CAF program.
The market for Smart City initiatives, in which cities use IoT technologies to collect and use insights gained from data to manage city assets, resources and services more efficiently, is a developing trend that is expected to accelerate due to the combination of increased data speeds and data capacity capabilities of wireless and wireline networks and developing IoT applications.  To address the expected escalating demands for resources of so many residents living, working, driving and interacting with each other, cities are looking at ways to become ‘smarter’ and more efficient in responding to these needs, including through Smart City initiatives to address and improve traffic flow, public safety and energy efficiency.  According to a recent article by Forbes Magazine, an estimated two-thirds of cities globally are investing in Smart City technologies, with spending projected to reach $135 billion in 2021 for IoT technologies such as smart utility meters, intelligent traffic signals, e-government applications, Wi-Fi kiosks and radio frequency identification sensors in the pavement. We believe that opportunities for installation and maintenance of both Smart City and smart home technologies will over time provide our install-to-the-home group opportunities for future growth, providing an offset to declining trends in subscribership for satellite TV.
We believe that we are well-positioned, as one of the largest providers of communications infrastructure services, to substantially benefit from the expected multi-year significant and broad opportunities in the telecommunications market as previously described.
Opportunities in our Oil and Gas Segment
We are one of the largest pipeline contractors in North America, with a balanced portfolio of service offerings, including union and non-union services, for the construction and maintenance of large diameter (“long-haul”) pipeline, midstream pipeline, gathering lines and related compressor and pumping stations and treatment plants. Demand for pipeline infrastructure and the related level of oil, natural gas and product pipeline construction activity has grown significantly in recent years as technological advances and increasingly cost-effective drilling, completion and production have significantly increased producible North American oil and natural gas reserves. Technological advances in 3D seismic imaging, digitization and data analysis have led to significant improvements in the identification of oil and natural gas reserves as well as the precision with which drilling operations can be performed, lowering the cost of production and maximizing output.
The effect of these advances on oil and gas production activities in North America has also driven changes in the geographic locations of North American energy production. The increase in oil and natural gas production across multiple basins, such as the Permian, Bakken and Marcellus/Utica basins, has led the industry to initiate actions to address ‘takeaway’ capacity issues, whereby more pipeline infrastructure is required to move production to market. As a result, construction of additional pipeline capacity across multiple basins and throughout the U.S. is underway and in plans for future development to improve available distribution and reduce transportation costs.
According to the Department of Energy’s (“DOE”) Short-Term Energy Outlook 2020, the U.S., which was already a net exporter of natural gas, also became a net exporter of oil for the first time since the early twentieth century. In October 2019, Enverus Drillinginfo predicted that oil production in the Permian Basin, which accounts for approximately 35% of all U.S. oil production, will increase four-fold, from 4.3 million barrels/day to 17.3 million barrels/day over the next ten years. These trends have driven oil and natural gas pipeline construction in recent years and are expected to continue. Additionally, industry reporting indicates that the abundance of low-cost North American natural gas will continue to drive growth of natural gas as a source of lower-carbon power generation, both in the U.S. and abroad. According to the DOE’s Annual Energy Outlook 2020, U.S. natural gas continued to surpass coal and hydroelectric power as the leading fuel type for electric power generation in 2019, and the U.S. continues to produce historically high levels of natural gas and crude oil. Additionally, in recent years, demand for liquified natural gas (“LNG”) exports has risen dramatically, driven in part by the easing of certain export regulations, which is expected to drive construction of pipeline infrastructure for the transport of LNG to coastal export facilities in North America.
These trends are expected to continue to drive demand for North American oil and gas production, creating opportunities for new pipeline infrastructure throughout. Significant investment in pipeline infrastructure will be required to move the increased volumes of oil and gas production to refining centers, distribution hubs, LNG export facilities and industrial users throughout North America, as well as to meet demand resulting from the desire to convert the transportation of oil and gas from traditional methods, such as truck and rail transport, to lower cost and safer pipeline infrastructure. In its August 2019 Oil & Gas Pipeline Construction in the US report, IBISWorld predicts that capital expenditures by energy producers for pipeline infrastructure in the U.S. will grow at an annualized rate of 1.6% over the next five years to almost $70 billion. In addition to potential opportunities in the U.S., initiatives in Mexico are expected to provide long-term growth opportunities. According to the Pipeline & Gas Journal’s 2020 Global Pipeline Construction Outlook, there were approximately 32,000 miles of new and planned pipeline projects within North America at the end of 2019. We anticipate that demand for pipeline infrastructure in North America will provide continued opportunities for years to come, and that our diverse capabilities and expertise will enable us to continue to be a leading service provider in this market. We also believe that future opportunities exist for

6



upgrades to existing pipeline infrastructure, including pipeline integrity and maintenance upgrades, replacement and modernization efforts, including digitization and other technology upgrades and upgrades to address safety regulations.
We believe that the above-mentioned trends will support continued levels of project activity, continuing a multi-year cycle of demand for pipeline construction projects, and that we are well-positioned to benefit from these trends.
Opportunities in our Electrical Transmission Segment
The U.S. electrical transmission and distribution infrastructure (the “grid”), comprising a network of electricity generation, high voltage transmission lines, substations and distribution lines that bring power to homes and businesses, will continue to require significant ongoing maintenance, upgrade and expansion to continue delivery of reliable and affordable power, as well as to address future grid resiliency and changing energy supply and distribution requirements. Increased investment in electrical infrastructure will be required to address increasing demand, modernize the grid and strengthen aging infrastructure. According to a May 2019 S&P Global Market Intelligence report, electric transmission and distribution infrastructure capital expenditures were projected to exceed $50 billion in 2019, driven by the need to upgrade aging infrastructure, digitize, and secure the grid against natural and man-made disasters, including storms, hurricanes and wildfires as well as potential cyber attacks. Increasing levels of disruption from natural disasters, such as hurricanes and wildfires continue a pattern that is expected to lead to required incremental future investment in transmission and distribution systems by utility companies. In addition, clean energy production trends are expected to lead to additional electric infrastructure investment, with shifting trends in power generation to cleaner energy sources, such as natural gas and renewables, while older power plants, including coal-fired and nuclear plants are retired or repurposed.

According to the DOE’s Annual Energy Outlook 2020, the percentage of electricity generated by renewable sources is expected to double to almost 40% by 2050. Future demand for electrical transmission and distribution infrastructure is also expected to result from grid resiliency efforts, technological advances, digitization, expected growth in usage of electric/hybrid vehicles, Smart City initiatives and the continued development of electrical power generation from renewable power sources, among others. The expected growth in demand for, and deployment of, electrical power generation from renewable energy sources will require significant investment in transmission lines, as wind and solar power generation resources are typically located in remote areas of the country, far from industrial users and major population centers.  Growth in electrical power generation from renewable sources in the U.S. will require the grid to be updated. Transmission lines will be required to connect the power generated from renewable energy sources to the grid and infrastructure will be required to provide for grid-scale storage of electricity from renewable energy sources, as well as to provide grid flexibility that can accommodate the related supply and demand for these new energy sources.
According to the DOE’s Annual Energy Outlook 2020, almost 650 net gigawatts of new electricity generating capacity are expected to be added in the U.S. through 2050, requiring significant investment in transmission and distribution by electric utility companies. We believe significant capital investment in the transmission and distribution system will continue to be required to meet the above-mentioned needs, and that we are well-positioned to benefit from these trends.
Opportunities in our Power Generation and Industrial Segment
Growing concerns with climate change, the desire to reduce greenhouse gas emissions and growing corporate initiatives for smaller, standalone distributed generation facilities, together with certain regulatory and other policy initiatives at the federal, state and municipal levels, have spurred demand for ‘clean’ energy production from sustainable power sources, including environmentally sensitive electrical power production from renewable sources such as wind, solar and biomass. Currently, almost 40 states, as well as the District of Columbia and four territories, have adopted renewable portfolio standards (“RPS”) or renewable energy goals. States have created these standards to diversify their energy resources, promote domestic energy production and encourage economic development. Renewable energy policies have helped to drive the U.S. market for wind, solar and other renewable energy sources. According to a January 2020 publication by BloombergNEF, U.S. investment in renewable energy capacity approximated $55 billion in 2019, an increase of almost 30% from 2018 levels. In addition, growing efforts to address electric grid resiliency are expected to drive growth in renewables, as utilities and their customers increasingly consider renewable microgrids combined with energy storage solutions to support critical facilities.
The DOE’s Annual Energy Outlook 2020 projects that almost 120 gigawatts of new wind and solar capacity will be added from 2020 to 2023 and predicts that renewable power generation will exceed that of natural gas-fired generation after 2045, contributing almost 40% of U.S. power generation capacity by 2050. Advancing technologies and improvements in cost and scalability of renewable energy projects are making these energy sources, particularly solar power projects, increasingly competitive. As a result, we expect these trends will continue to drive demand for construction of renewable infrastructure in the coming years. According to a January 2020 report by IHS Markit, U.S. solar installations are expected to grow 20% in 2020, and the DOE’s Annual Energy Outlook 2020 projects continued growth in new generating capacity from solar installations through 2050 due to declining costs for solar photovoltaic (PV) panels. In addition, we believe that replacement and repowering of existing wind turbines and foundations with next generation, higher efficiency turbines, as well as maintenance of aging wind farms, will provide increased opportunities for wind infrastructure projects.
Investment in the renewable energy industry is partially dependent on federal and state tax incentives. Currently, there are certain federal tax incentives applicable to renewable energy projects, which are expected to be phased out beginning in 2021. In order to qualify for these tax credits, construction must begin before the end of 2020 and the project must be placed in service prior to the end of 2024.  Notwithstanding the potential phase-out of these tax incentives, the continued and increasing trends towards renewable portfolio standards, coupled with growing corporate initiatives to reduce greenhouse gas emissions, are expected to continue to drive growth in renewable energy projects. In addition, due to recent cost declines and improved efficiencies, a recent article by BloombergNEF indicates that wind and solar energy projects are becoming competitive with traditional energy sources. See Item 1A. “Risk Factors - The renewable energy industry is reliant on tax incentives, the availability of which may be uncertain and could adversely affect demand for our services.”
Additionally, industrial plant construction opportunities exist in a wide variety of industries, including in the renewable energy industry, as power companies explore ways to reduce their carbon footprint. The low price and environmental advantage of cleaner burning natural gas is expected to continue to drive demand for gas-fired electrical generating plants and conversions of coal-fired power plants to natural gas. A wide variety of

7



industries may seek to expand, convert or construct new plants to take advantage of this economical, cleaner, lower cost and lower carbon fuel source. Biofuel and biomass as alternative fuel sources also present opportunities for the renewable energy market. Industrial facilities and power plants in the biofuels/biomass, food processing, natural gas, petroleum and related industries present opportunities as additional domestic energy reserves are produced, transported and processed.
We are one of the leading renewables contractors in North America, with expertise in wind, solar and biomass, as well as industrial and other power plant construction, and expect to benefit from these market trends.

Our water pipeline services increase the efficiency of water used in energy field operations in an environmentally focused manner. We build expansive water pipeline networks, which allow for the recycling of water, thereby reducing fresh water requirements as well as the amount of water disposed. Additionally, the use of water pipelines reduces truck traffic, resulting in lower carbon emissions.
Strategy
The key elements of our business strategy are as follows:
Focus on Growth Opportunities. We believe that our end-markets offer multiple growth opportunities, and we expect continued spending by key customers in many of the industries we serve. We expect development of wireless and wireline/fiber infrastructure; oil and natural gas pipeline infrastructure; expansion, maintenance and upgrades of electrical transmission capacity and the electrical distribution grid; development of power generation infrastructure, including renewables; and heavy civil and industrial infrastructure construction projects to be areas of investment and opportunity in the coming years. We intend to use our broad geographic presence, technical expertise, financial and operational resources, customer relationships and full range of services to capitalize on these trends and grow our business.
Operational Excellence. We seek to improve our profit margins and cash flows by focusing on services and projects that have high margin potential. We also strive to identify opportunities for leverage within our business, such as deploying resources across multiple customers and projects in order to enhance our operating effectiveness and utilization rates. We also seek to maintain strong working capital management practices. Our management team pursues actions and programs designed to achieve these goals, such as increasing accountability throughout our organization, effectively managing customer contract bidding procedures, evaluating opportunities to improve our working capital cycle time, hiring and retaining experienced operating and financial professionals, and developing, expanding and integrating the use of financial systems and information technology capabilities within our business.
Maintain Conservative Capital Structure. We evaluate our capital structure on an ongoing basis and have expanded our financial resources in recent years. We believe that we have sufficient capital resources to fund our planned operations. As of December 31, 2019, we had approximately $0.9 billion of borrowing availability under our revolving credit facility, with aggregate borrowing commitments of $1.75 billion under our senior secured credit facility and $400 million of 4.875% senior notes due 2023. We may consider opportunities to borrow additional funds, or to refinance, repurchase or retire outstanding debt or repurchase shares as part of our ongoing capital structure evaluation. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Summary of Financial Condition, Liquidity and Capital Resources,” for details pertaining to our debt instruments and share repurchase activities.
Leverage Core Performance and Expertise through Strategic Acquisitions and Other Arrangements. We may pursue selected acquisitions, investments and strategic arrangements that allow us to expand our operations, service offerings, customer base or geographic reach. We have diversified our business and expanded our service offerings and geographic footprint in recent years, both organically and through acquisition. In order to maximize their potential, our strategy is to integrate acquired businesses into our operations and internal control environment in a timely and efficient manner. We evaluate our business on a regular basis, and from time to time, we may divest certain businesses or assets, or curtail selected business activities or operations that do not produce adequate revenue or margin or that no longer fit within our long-term business strategy.
Services
Our core services are the engineering, building, installing, maintaining and upgrading of infrastructure, primarily for communications, oil and gas, utility and power generation customers. We provide similar services to each of these customers, including:
Build. We build infrastructure projects for customers across a range of industries. We specialize in building underground and overhead distribution systems, including trenches, conduits, cell towers, cable and power lines, which provide wireless and wireline/fiber communications; natural gas, crude oil and refined product transport pipelines; electrical power generation, transmission and distribution systems; power generation infrastructure, including renewable energy; heavy industrial plants; compressor and pump stations and treatment plants; water and sewer infrastructure, including water pipelines; and other civil construction infrastructure.

Install. We install electrical and other energy distribution and transmission systems, power generation facilities, buried and aerial fiber optic and other cables, satellite dishes, home automation and energy management solutions in a variety of environments for our customers. In connection with our installation work, we deploy and manage network connections that involve our customers’ hardware, software and network equipment.
Maintain and Upgrade. We offer 24 hour/365 days-a-year maintenance and upgrade support to our customers. Our comprehensive service offerings include the regular maintenance of our customers’ distribution facilities, networks and infrastructure, including natural gas and petroleum pipeline, communications, electrical distribution and transmission, power generation and heavy civil infrastructure. We also provide emergency services for accidents or storm damage. Our upgrade work ranges from routine replacements and upgrades to major overhauls.
Customers
We have longstanding relationships with many customers, and often provide services under master service and other service agreements, which are generally multi-year agreements. Our master service agreements are typically exclusive up to a specified dollar amount per work order for each defined geographic area, but do not obligate our customers to undertake any infrastructure projects or other work with us. Work performed under master service and other service agreements is usually generated through work orders, each of which is performed for a fixed fee. Services provided under these agreements range from engineering, project management and installation work to maintenance and upgrade services. Master service and other service agreements are frequently awarded on a competitive bidding basis, although customers are sometimes willing to negotiate contract extensions beyond their original terms without re-bidding. Our master service and other service agreements have various terms, depending upon the nature of the services provided, and typically provide for termination on short or no advance notice. For the years ended December 31, 2019, 2018 and 2017, 36%, 35% and 36%, respectively, of our revenue was derived from projects performed under master service and other service agreements.
The remainder of our work is generated pursuant to contracts for specific projects or jobs requiring the construction and installation of an entire infrastructure system or specified units within an entire infrastructure system. Customers are billed with varying frequency, the timing of which is generally dependent upon advance billing terms, milestone billings based on completion of certain phases of the work, or when services are provided. Under the typical payment terms of master and other service agreements and contracts for specific projects, the customer makes progress payments based on quantifiable measures of performance as defined in the agreements. Some of our contracts include retainage provisions, under which a portion of the contract amount (generally, from 5% to 10% of billings) can be retained by the customer until final contract settlement.
We believe that our industry experience, technical expertise and reputation for customer service, as well as the relationships developed between our customers and our senior management and project management teams are important to our being retained by our customers. See Note 13 - Segments and Related Information and Note 14 - Commitments and Contingencies in the notes to the audited consolidated financial statements, which are incorporated by reference, for customer concentration information.
Backlog
Estimated backlog represents the amount of revenue we expect to realize over the next 18 months from future work on uncompleted construction contracts, including new contracts under which work has not begun, as well as revenue from change orders and renewal options. Our estimated backlog also includes amounts under master service and other service agreements and includes our proportionate share of estimated revenue from proportionately consolidated non-controlled contractual joint ventures. Estimated backlog for work under master service and other service agreements is determined based on historical trends, anticipated seasonal impacts, experience from similar projects and estimates of customer demand based on communications with our customers. We expect to realize approximately 80% of our estimated year end 2019 backlog in 2020. The following table presents 18-month estimated backlog by reportable segment, as of the dates indicated:

Approximately half of our backlog as of December 31, 2019 is attributable to amounts under master service or other service agreements, pursuant to which our customers are not contractually committed to purchase a minimum amount of services. Most of these agreements can be canceled on short or no advance notice. Timing of revenue for construction and installation projects included in our backlog can be subject to change as a result of customer delays or cancellations, regulatory or other delays 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. We occasionally experience postponements, cancellations and reductions in expected future work from master service agreements and/or construction projects due to changes in our customers’ spending plans, market volatility, regulatory delays and/or 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.
Backlog is not a term recognized under accounting principles generally accepted in the United States (“U.S. GAAP”); however, it is a common measurement used in our industry. Our methodology for determining backlog may not, however, be comparable to the methodologies used by others. Backlog differs from the amount of our remaining performance obligations, which are described in Note 1 - Business, Basis of Presentation and Significant Accounting Policies in the notes to the audited consolidated financial statements, which is incorporated by reference. As of December 31, 2019, total 18-month backlog differed from the amount of our remaining performance obligations due primarily to the inclusion of $3.0 billion of estimates of future revenue under master service and other service agreements within our backlog estimates, as described above, and the exclusion of approximately

10



$0.3 billion of remaining performance obligations in excess of 18 months, which amount is not included in the backlog estimates above. Backlog expected to be realized in 2020 differed from the amount of remaining performance obligations expected to be recognized for the same period due primarily to the inclusion of approximately $1.7 billion of estimates of future revenue under master service and other service agreements that is included within the related backlog estimate.
Sales and Marketing
Our customers increasingly require resources from multiple disciplines. Therefore, our subsidiary services companies market their services not only individually, but also in combination with other companies, including other MasTec companies and independent companies, to provide what we believe are the most efficient and effective solutions to meet our customers’ demands. Through our unified MasTec® brand and an integrated organizational structure designed to permit rapid deployment of labor, equipment and materials, we are able to quickly and efficiently allocate resources to meet customer needs. We offer services that are branded under the MasTec® service mark and other service marks.
We have developed a marketing plan emphasizing the MasTec® registered service mark and trade names of certain acquired companies, as well as an integrated service offering to position ourselves as a provider of a full range of service solutions, providing services including installation as well as sophisticated engineering, design and integration. We believe our longstanding relationships with customers and our reputation for reliability and efficiency facilitate our recurring business. Our marketing efforts are principally carried out by the management of our business units and project groups in coordination with our corporate business development organization. Our management team has many years of industry experience, both at the service provider level, and in some cases, with the customers we serve. Our business unit and project group managers market directly to existing and potential customers for new contracts and also seek our inclusion on lists of vendors invited to submit proposals for service agreements and individual projects. We also market our services in conjunction with certain business partners, strategic investments and arrangements. Our executive management supplements these efforts at the national and international level.
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 monitor and improve compliance with safety procedures and regulations. We also provide company-wide training where appropriate, including for information technology and cyber security as well as for workplace and employee awareness programs.
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. Our insurance policies are subject to high deductibles and we are self-insured up to the amount of the deductible. We maintain insurance policies for workers’ compensation, general liability and automobile liability that are subject to per claim deductibles. We also maintain excess umbrella coverage and an insurance policy with respect to employee group medical claims, which is subject to annual per employee maximum losses. We are required to post collateral to certain of our insurance carriers, generally in the form of letters of credit, surety bonds and cash. See Note 14 - Commitments and Contingencies in the notes to the audited consolidated financial statements, which is incorporated by reference.
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 of, 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 on 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 us manage our work flow. Our independent contractors typically provide their own vehicles, tools and insurance coverage. We are not dependent on any one independent contractor. We need working capital to support seasonal variations in our business, including the spending patterns of our customers and the effects of weather conditions on external construction and maintenance work, both of which can influence the timing of spending to support related customer demand. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Financial Condition, Liquidity and Capital Resources - Working Capital,” which is incorporated by reference.
Competition
Our industry is highly competitive and highly fragmented. We compete with a number of companies in the markets in which we operate, ranging from small local independent companies to large national firms, including Quanta Services, Inc., MYR Group, Inc., Dycom Industries, Inc., Jacobs Engineering Group Inc., Primoris Services Corporation, Pike Electric, Inc., Bechtel Corporation, D.H. Blattner & Sons, Inc., M.A. Mortenson Company, Black & Veatch and Nexius.
Certain barriers to entry exist in the markets in which we operate, including adequate financial resources, technical expertise, high safety ratings and a proven track record of operational success. Some of our customers employ their own personnel to perform infrastructure services of the type we provide. We compete based upon our industry experience, technical expertise, financial and operational resources, geographic presence, industry reputation, safety record and reputation for customer service. 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, and price is often a principal factor in determining which service provider is selected.
Regulation, Environmental and Climate Change Matters
We are subject to state and federal laws that apply to businesses generally, including laws and regulations related to labor relations, wages, worker safety and environmental protection. While many of our customers operate in regulated industries (for example, utilities regulated by the public

11



service commission or communications companies regulated by the Federal Communications Commission (“FCC”), we are not generally subject to such regulation and oversight.
As a contractor, our operations are subject to various laws, including:
regulations related to worker safety and health, including those established by the Occupational Safety and Health Administration (“OSHA”) and state equivalents;
regulations related to vehicle registrations, including those of the states and the U.S. Department of Transportation (“DOT”);
contractor licensing requirements;
permitting and inspection requirements; and
building and electrical codes.
We are also subject to numerous environmental laws, regulations and programs, including the handling, transportation and disposal of non-hazardous and hazardous substances and wastes, laws governing emissions and discharges into the environment, including discharges into air, surface water, groundwater and soil, and programs related to the protection of endangered species.
We have a substantial investment in construction equipment that utilizes fuel. Any changes in laws requiring us to use equipment that runs on alternative fuels could require a significant investment, which could have a material adverse effect on our results of operations, cash flows and liquidity.
We also are subject to laws and regulations that impose liability and cleanup responsibility for releases of hazardous substances into the environment. Under certain of these laws and regulations, liabilities can be imposed for cleanup of properties, regardless of whether we directly caused the contamination or violated any law at the time of discharge or disposal. The presence of contamination from such substances or wastes could interfere with ongoing operations or adversely affect our business. In addition, we could be held liable for significant penalties and damages under certain environmental laws and regulations. Our contracts with customers may also impose liabilities on us regarding environmental issues that arise through the performance of our services. From time to time, we may incur costs and obligations related to environmental compliance and/or remediation matters.
We believe we have all material licenses and permits needed to conduct operations and that we are in material compliance with all applicable regulatory and environmental requirements. We could, however, incur significant liabilities if we fail to comply with such requirements.
The potential effects of climate change on our operations is highly uncertain. Climate change may result in, among other things, changes in rainfall patterns, storm patterns and intensities and temperature levels. Our operating results are significantly influenced by weather. Therefore, major changes in weather patterns could have a significant effect on 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, which could negatively affect our revenue and profitability. Climate change could also affect our customers and the projects that they award. Demand for power projects, underground pipelines or other projects could be negatively affected by significant changes in weather or from legislation or regulations governing climate change.
Financial Information About Geographic Areas
We operate throughout North America, primarily in the United States and Canada, and, to a lesser extent, in Mexico and the Caribbean. See Note 13 - Segments and Related Information in the notes to the audited consolidated financial statements, which is incorporated by reference.
Employees
For the twelve month period ended December 31, 2019, we had an average of approximately 21,000 employees, of which approximately 3,100 were represented by unions or were subject to collective bargaining agreements. The number of union employees employed at a given time, and the plans in which they participate, varies depending upon the location and number of ongoing projects and the need for union resources in connection with those projects.
We hire employees from a number of sources, including our industry, trade schools, colleges and universities. Our primary sources for employees include promotion from within, team member referrals, direct recruiting and various forms of advertising, including social media. We attract and retain employees by offering competitive salaries, technical training opportunities, bonus opportunities, stock ownership, employee incentive programs and a comprehensive benefits package. We believe that our team culture, along with our focus on employee training and career development helps us to attract and retain employees. Our employees participate in ongoing educational programs, many of which are internally developed, to enhance their technical and management skills through classroom and field training. We provide opportunities for promotion and mobility within our organization, which we also believe helps us to retain our employees. We believe we have good employee relations.

ITEM 1A.
RISK FACTORS
Our business is subject to a variety of risks and uncertainties, including, but not limited to, the risks and uncertainties described below. Additional risks and uncertainties not known to us or not described below could also negatively affect our operations. If any of the risks described below, or other risks that are unknown to us were to occur, our business, financial condition, results of operations and cash flows could suffer, and/or the trading price of our common stock could decline. We also may not be able to achieve our goals or expectations. You should carefully consider the risks described below, together with all of the other information in this Form 10-K, including our Cautionary Statement Regarding Forward-Looking Statements described above.
Risks Related to Our Industry and Our Customers’ Industries
Many of the industries we serve are subject to customer consolidation as well as rapid technological and regulatory changes. Our inability or failure to adjust to such changes could result in decreased demand for our services. Additionally, demand for construction services depends on industry activity and expenditure levels, which can be affected by a variety of factors, including changes in governmental regulations and policies.
We derive a substantial portion of our revenue from customers in industries that are subject to consolidation, rapid changes in technology, changing consumer demands and governmental regulation. Consolidation of any of our customers, or groups of our customers, could result in the loss of customers or could affect customer demand for the services we provide. Many of our customers face stringent regulatory and environmental requirements and permitting processes, including governmental regulations and policies. Regulatory requirements pertaining to permitting could result in project cancellations or deferrals of projects, which could materially affect demand for our services. The industries we serve are also subject to effects of environmental regulation, climate change initiatives and political or social activism, any of which could result in reduced demand for our services and/or delays or cancellations of current or planned future projects. Additionally, technological advances in the markets we serve could render existing projects or technologies uncompetitive or obsolete. Such changes in technology or our failure to rapidly adopt and master new technologies as they are developed in any of the industries we serve could reduce demand for our services. Any of the above factors could have a material adverse effect on our results of operations, cash flows and liquidity.
Unfavorable market conditions, market uncertainty and/or economic downturns could reduce capital expenditures in the industries we serve or could adversely affect our customers, which could result in decreased demand for the services we provide or impair our customers’ ability to pay for our services.
We continually monitor our customers’ industries and their relative health compared to the economy as a whole because we have in the past been negatively affected by economic downturns. Demand for our services has been, and will likely continue to be, cyclical in nature and vulnerable to general downturns in the U.S. economy and the economies of the countries in which we operate. Unfavorable market conditions, market uncertainty and/or economic downturns could have a negative effect on demand for our customers’ services or the profitability of their services. Our customers may not have the ability to fund capital expenditures for infrastructure, or may have difficulty obtaining financing for planned projects during economic downturns. Uncertain or adverse economic conditions could reduce the availability of debt or equity financing for our customers, which could reduce their capital spending and/or result in project cancellations or deferrals. Any of these conditions could materially and adversely affect our results of operations, cash flows and liquidity, and could add uncertainty to our backlog determinations.
The oil and gas markets have historically been volatile and are likely to continue to be volatile. Oil and gas prices are subject to large fluctuations in response to changes in supply and demand, as well as market uncertainty and a variety of other factors that are beyond our control. Demand for pipeline construction services is sensitive to the level of activity in the oil and gas industry as well as industrial and utility customer demand. Other economic factors, such as reductions in new housing starts, can also negatively affect demand for our services, in particular for “last mile” infrastructure services, including for communications infrastructure, electrical utility transmission and grid connection and pipeline construction services. Additionally, an economic downturn could adversely affect our communications and customer fulfillment customers if services are ordered at a reduced rate, or not at all. A decrease in demand for the services we provide from any of the above factors, among others, could materially and adversely affect our results of operations, cash flows and liquidity.
An impairment of the financial condition of one or more of our customers due to economic downturns could hinder their ability to pay us on a timely basis. In the past, we incurred significant losses from customers who filed for bankruptcy or experienced financial difficulties following a general economic downturn, in which certain industry factors worsened the effect of the overall economic downturn on those customers. 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 affect 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 results of operations, cash flows and liquidity.

13



Our industry is highly competitive, which could reduce our market share and harm our financial performance.
Our industry is highly fragmented, and 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, which could reduce the amount of services our customers request us to perform. There are relatively few barriers to entry into certain of the markets in which we operate and, as a result, any organization that has adequate financial resources and access to technical expertise and skilled personnel may become a competitor. Most of our customers’ work is awarded through bid processes, and our project bids may not be successful. Our results of operations, cash flows and liquidity could be materially and adversely affected if we are unsuccessful in bidding for projects or renewing our master service agreements, or if our ability to win such projects or agreements requires that we accept lower margins.
Risks Related to Our Business
Our failure to properly manage projects, or project delays, could result in additional costs or claims, which could have a material adverse effect on our operating results, cash flows and liquidity.
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, including the timely deployment of appropriate resources, including third-party contractors and our own personnel. Our results of operations, cash flows and liquidity 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 failure to timely obtain permits or rights-of-way or to meet other regulatory requirements, weather-related delays and governmental, market, political and other factors, some of which are beyond our control, could result in cancellations or deferrals of project work, which could lead to a decline in revenue, or, for project deferrals, could cause us to incur costs for standby pay, and could lead to personnel shortages on other projects scheduled to commence at a later date.
We could also encounter project delays due to local opposition, including political and social activism, which could include injunctive actions or public protests related to the siting of oil, natural gas, or electric power transmission lines or for power generation or other facilities, and such delays could adversely affect our project margins. 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 results of operations, cash flows and liquidity. Further, any defects or errors, or failures to meet our customers’ expectations, could result in large damage claims against us. Due to 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 could substantially exceed the amount we can charge for our associated services.
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 project losses. These types of claims can often occur due to matters such as owner-caused delays or changes from the initial project scope, which result in additional costs, 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 promptly recover on these types of claims could have a material adverse effect on our liquidity and financial results.
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 master service and other service agreements. Under these contracts, we typically set the price of our services on a per unit or aggregate basis and assume the risk that costs associated with our performance may be greater than what we estimated. We also enter into contracts for specific projects or jobs that require the installation or construction of an entire infrastructure system or specified units within an infrastructure system, many of which are priced on a fixed price or per unit basis. If actual costs to complete a project exceed our original estimates, our profitability will be reduced. Additionally, if estimated costs to complete the remaining work for a project exceed the expected revenue to be earned, the full amount of such expected loss 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 could negatively affect these estimates, including changes in expected productivity levels, conditions at work sites differing materially from those anticipated at the time we bid on the contract and higher than expected costs of labor and/or materials. These variations, along with other risks inherent in performing fixed price contracts, could cause actual project results to differ materially from our original estimates, which could result in lower margins than anticipated, or losses, which could reduce our profitability, cash flows and liquidity.
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 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 that affect our ability to complete a project as

14



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, cancellations, 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 affect our reputation or relationships with our customers, which could adversely affect our ability to secure new contracts.
We recognize revenue for certain projects using the cost-to-cost method of accounting; therefore, variations of actual results from our assumptions could reduce our profitability.
We recognize revenue from fixed price contracts, as well as for certain projects pursuant to master and other service agreements, over time utilizing the cost-to-cost measure of progress, or the “cost-to-cost” method of accounting, 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 cost-to-cost 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 contract 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, changes in job performance, job conditions and management’s assessment of expected variable consideration. 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 such losses are determined. Any such adjustments could result in reduced profitability and negatively affect our results of operations.
We derive a significant portion of our revenue from a few customers, and the loss of one or more of these customers, or a reduction in their demand for our services, could impair our financial performance.
Our business is concentrated among relatively few customers, and a substantial proportion of our services are provided on a non-recurring, project-by-project basis. Our revenue could significantly decline if we were to lose one or more of our significant customers, or if one or more of our customers reduce the amount of business they provide to us and/or elect to perform the work that we provide using in-house service teams. In addition, our results of operations, cash flows and liquidity could be negatively affected 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 affect our results of operations, cash flows and liquidity. See Note 1 - Business, Basis of Presentation and Significant Accounting Policies, Note 13 - Segments and Related Information and Note 14 - Commitments and Contingencies for revenue concentration information.
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 is, therefore, an uncertain indicator of future operating results.
Our backlog consists of the estimated amount of revenue we expect to realize from future work on uncompleted contracts, including new contracts under which work has not begun, as well as revenue from change orders and renewal options and our proportionate share of estimated revenue from proportionately consolidated non-controlled contractual joint ventures. A significant portion of our 18-month backlog is attributable to master service agreements and other service agreements, none of which require our customers to purchase a minimum amount of services and are cancelable on short or no advance notice. The balance of our backlog is our estimate of work to be completed under contracts for specific projects. Backlog amounts are determined based on estimates that incorporate historical trends, anticipated seasonal impacts, experience from similar projects and estimates of customer demand based on 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 experienced postponements, cancellations and reductions in expected future work due to changes in our customers’ plans, market volatility, regulatory delays and/or 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, our results of operations, cash flows and liquidity would be materially and adversely affected.
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, if contract awards are delayed, or if there is a significant reduction in the level of services we provide.
Our estimates of future performance and results of operations depend, among other factors, on 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 forecast the need for our 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, our ability to manage attrition, 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, professional knowledge and experience, these estimates may not be accurate 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 project needs. If an expected contract award is delayed or not received, we could incur costs resulting from underutilization of our workforce, redundancy of facilities, or from efforts to right-size our workforce and/or operations, which could reduce our profitability and cash flows.
Many of our contracts do not obligate our customers to undertake any infrastructure projects or other work with us, and most of our contracts may be canceled on short or no advance notice, which could reduce our revenue. In addition, certain of our contracts are subject to our customers’ ability to secure financing or other conditions and therefore, may not result in revenue or profits.
We derive a significant portion of our revenue from multi-year master service and other service agreements, under which we provide project services through work orders within defined geographic areas on a fixed fee basis. Under these agreements, our customers have no obligation to undertake any infrastructure projects or other work with us. This makes it difficult to estimate our customers’ demand for our services. A significant decline in the volume of work our customers request us to perform under these service agreements could negatively affect our results of operations, cash flows and liquidity. In addition, most of our contracts are cancelable on short or no advance notice, ranging from immediate cancellation to cancellation upon

15



180 days notice, even if we are not in default under the contract. Many of our contracts, including our service agreements, are periodically open to public bid. We may not be the successful bidder on existing contracts that are re-bid. For our services that are provided on a non-recurring, project-by-project basis, we could experience a reduction in revenue, profitability and liquidity if our customers cancel a significant number of contracts, or if we fail to win a significant number of existing contracts upon re-bid, or if we complete the required work under a significant number of our non-recurring projects and cannot replace them with similar projects. Additionally, from time to time, we enter into contracts that contain financing or other conditions that must be satisfied before we can begin work. Certain of these contracts may not result in revenue or profits if our customers are unable to obtain financing or to satisfy other conditions associated with such projects.
Our business is seasonal and affected by the spending patterns of our customers as well as weather conditions and natural catastrophes, which exposes us to variations in quarterly results.
Some of our customers reduce their expenditures and work order requests towards the end of the calendar year. In addition, adverse weather conditions, particularly during the winter season, can 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, wildfires or flooding could affect our ability to perform outdoor services or utilize equipment and crews in affected regions. These events, as well as global economic effects resulting from concerns over infectious diseases or other health issues, could also have an effect on demand for our services which could negatively affect our results of operations, cash flows and liquidity.
Acquisitions and investments involve risks that could negatively affect our operating results, cash flows and liquidity.
We have made, and may continue to make, strategic acquisitions and investments. Acquisitions may expose us to operational challenges and risks, including:
the ability to profitably manage the acquired business or successfully integrate the operations, internal controls and procedures, financial reporting and accounting systems of the acquired business into our business;
increased indebtedness and contingent earn-out obligations;
the ability to fund cash flow shortages that may occur if anticipated revenue is not realized or is delayed, whether by general economic or market conditions, or other unforeseen difficulties;
the expense of integrating acquired businesses;
the availability of funding sufficient to meet increased capital needs;
diversion of management’s attention; and
the ability to retain or hire qualified personnel required for expanded operations.
We may not be able to identify suitable acquisition or strategic investment opportunities, or may be unable to obtain the required consent of our lenders and, therefore, may not be able to complete such acquisitions or strategic investments. We may pay for acquisitions or strategic investments with our common stock or with debt instruments, including convertible debt securities, which could dilute the ownership interests of our common shareholders, or we may decide to pursue acquisitions with which our investors may not agree. Borrowings or issuances of debt associated with these acquisitions could also result in higher levels of indebtedness, which could negatively affect our ability to service our debt within the scheduled repayment terms. In addition, in connection with most of our acquisitions, we agree to substantial future earn-out arrangements. To the extent we defer payment of an acquisition’s purchase price through a cash earn-out arrangement, it will reduce our cash flows in subsequent periods.
In addition, acquired companies may have liabilities that we failed, or were unable, to discover in the course of performing due diligence investigations. We cannot assure you that the indemnifications granted to us by sellers of acquired companies will be sufficient in amount, scope or duration to fully offset potential liabilities associated with acquired businesses. We may learn additional information about the businesses we have acquired that could materially adversely affect us, such as unknown or contingent liabilities, unprofitable projects and liabilities related to compliance with applicable laws. Any such liabilities, individually or in the aggregate, could have a material adverse effect on our business. Failure to successfully manage the operational challenges and risks associated with, or resulting from, our acquisitions could adversely affect our results of operations, cash flows and liquidity.
We generally require that key management and former principals of the businesses we acquire enter into non-competition agreements in our favor. Enforceability of these non-competition agreements varies from state to state, and state courts will generally examine all of the facts and circumstances at the time a party seeks to enforce a non-competition agreement; consequently, we cannot predict with certainty whether, if challenged, a court will enforce any particular non-competition agreement. If one or more former principals or members of key management of the businesses we acquire terminate their employment with us and the courts refuse to enforce the non-competition agreement entered into by such person or persons, we might be subject to increased competition, which could materially and adversely affect our operating results, cash flows and liquidity.
We have incurred goodwill and intangible asset impairment charges, and in the future, could incur additional impairment charges, which could harm our profitability.
We have significant amounts of long-lived assets, goodwill and intangible assets. When we acquire a business, we record goodwill equal to the excess of the amount we pay for the business, including anticipated future liabilities, over the estimated fair value of the net assets of the acquired business. We periodically review the carrying values of goodwill and intangible assets to determine whether such carrying values exceed their fair market values. Declines in the profitability of individual reporting units due to economic or market conditions or otherwise, as well as adverse changes in financial, competitive and other conditions, or other adverse changes in the key valuation assumptions contributing to the estimated fair value of our reporting units, could adversely affect the estimated fair values of the related reporting units, which could result in an impairment of the recorded balances of goodwill or intangible assets. See Note 3 - Goodwill and Other Intangible Assets in the notes to the audited consolidated financial statements, which

16



is incorporated by reference, for additional details. Changes in economic and capital market conditions, as well as the operating performance of our reporting units, could result in future impairment charges, which could adversely affect our financial condition and operating results.
Our financial results are based, in part, upon estimates and assumptions that may differ from actual results. In addition, changes in accounting principles may cause unexpected fluctuations in our reported financial information.
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 and accompanying notes. 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. See Note 1 - Business, Basis of Presentation and Significant Accounting Policies in the notes to the audited consolidated financial statements, which is incorporated by reference, for details of key estimates. 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.
In addition, accounting rules and regulations are subject to review and interpretation by the Financial Accounting Standards Board (the “FASB”), the SEC and various other governing bodies. A change in U.S. GAAP could have a significant effect on our reported financial results. Additionally, the adoption of new or revised accounting principles could require that we make significant changes to our systems, processes and controls. We cannot predict the effect of future changes to accounting principles, which could have a significant effect on our reported financial results and/or our results of operations, cash flows and liquidity.
Our operations could affect the environment or cause exposure to hazardous substances. In addition, our properties could have environmental contamination, which could result in material liabilities.
Our operations are subject to various environmental laws and regulations, including those dealing with the handling and disposal of waste products, polychlorinated biphenyls (“PCBs”), fuel storage and air quality. Certain of our current and historical construction operations have used hazardous materials and, to the extent that such materials are not properly stored, contained or recycled, they could become hazardous waste. Additionally, some of our contracts require that we assume the environmental risk of site conditions and require that we indemnify our customers for any damages, including environmental damages, incurred in connection with our projects. We may be subject to claims under various environmental laws and regulations, federal and state statutes and/or common law doctrines for toxic torts and other damages, as well as for natural resource damages and the investigation and clean-up of soil, surface water, groundwater, and other media under laws such as the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”). Such claims may arise, for example, out of current or former conditions at project sites, current or former properties owned or leased by us, or contaminated sites that have always been owned or operated by third parties. Liability may be imposed without regard to fault and may be strict and joint and several, such that we may be held responsible for more than our share of any contamination or other damages, or even for the entire share, and we may be unable to obtain reimbursement from the parties that caused the contamination.
A failure to comply with environmental laws could result in significant liabilities or harm our reputation, and new environmental laws or regulations could adversely affect our business.
Some of the work we perform is in underground environments. If the field location maps supplied to us are not accurate, or if objects are present in the soil that are not indicated on the field location maps, our underground work could strike objects in the soil containing pollutants and result in a rupture and discharge of pollutants. In such a case, we could incur significant costs, including clean-up costs, and we may be liable for significant fines and damages and could suffer reputational harm. Additionally, we sometimes perform directional drilling operations below certain environmentally sensitive terrains and water bodies. Due to the inconsistent nature of terrain and water bodies, it is possible that such directional drilling could cause a surface fracture releasing subsurface materials or drilling fluid. These releases alone or, in combination with releases that may contain contaminants in excess of amounts permitted by law, could potentially expose us to significant clean up and remediation costs, damages, fines and reputational harm, which could have a material adverse effect on our results of operations, cash flows and liquidity.
We also own and lease several facilities at which we store our equipment. Some of these facilities contain fuel storage tanks that may be above or below ground. If these tanks were to leak, we could be responsible for the cost of remediation as well as potential fines. New environmental laws and regulations, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or leaks, or the imposition of new clean-up requirements could require us to incur significant costs or result in new or increased liabilities that could have a material adverse effect on our results of operations, cash flows and liquidity. We are also subject to laws and regulations protecting endangered species. We may incur work stoppages to avoid violating these laws and regulations, or we may risk fines or other sanctions if we inadvertently violate these laws and regulations.
In addition, concerns about climate change could result in potential new regulations, regulatory actions or requirements to fund energy efficiency activities, any of which could negatively affect our customers and decrease demand for their services, or result in increased costs associated with our operations. There are significant environmental regulations under consideration to encourage the use of clean energy technologies and regulate emissions of greenhouse gases to address climate change. The establishment of rules limiting greenhouse gas emissions could affect our ability to perform construction services or to perform these services at current levels of profitability. For example, if new regulations were adopted regulating greenhouse gas emissions from sources such as cars and trucks, we could experience a significant increase in environmental compliance costs in light of our large fleet and the amount of construction machinery we own. New regulations may require us to acquire different equipment or change processes. The new equipment may not be available, or we may not be able to purchase or rent this equipment in a cost-effective manner. Compliance with any new laws or regulations regarding the reduction of greenhouse gases could result in significant changes to our operations and a significant increase in the cost of conducting our business. In addition, if our operations are perceived to result in high greenhouse gas emissions or to otherwise pose environmental risks, our reputation could suffer and/or we could experience a reduction in the amount of future work we are awarded. Project deferrals, delays or cancellations resulting from climate change initiatives and/or the effects of such regulations could adversely affect our business.
Many of our customers are highly regulated. New regulations, or changes to existing regulations, could adversely affect demand for our services and/or the profitability of those services.

17



Most of our communications customers are regulated by the FCC, and our energy customers are regulated by the Federal Energy Regulatory Commission (“FERC”), among others. In addition, our utility customers are regulated by state public utility commissions. These agencies could change their interpretation of current regulations and/or may impose additional regulations. Interpretative changes or new regulations having an adverse effect on our customers and/or 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.
Additionally, various federal, state, local, or foreign legislative and regulatory initiatives have been undertaken that could result in additional requirements or restrictions being imposed, including for drilling and completion operations. Future regulations or restrictions that might be adopted could lead to operational delays and increased operating costs for our customers in the oil and gas industry, which could result in reduced capital spending and/or delays or cancellations of future oil and gas infrastructure projects that could materially and adversely affect 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 data security breaches could adversely affect our ability to operate, and/or 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. We also rely, in part, on third-party software and information technology to run certain of our critical accounting, project management and financial information systems. From time to time, we experience system interruptions and delays. Our operations could be interrupted or delayed, or our data security could be breached, if we are unable to deploy software and hardware, gain access to, or effectively maintain and upgrade our systems and network infrastructure and/or take other steps to improve and otherwise protect our systems. In addition, our information technology and communications systems and our operations could be damaged or interrupted by cyber attacks and/or physical security risks, including from natural disasters, power loss, telecommunications failures, intentional or inadvertent user misuse or error, failures of information technology solutions, computer viruses, malicious code, ransomware attacks, acts of terrorism and physical or electronic security breaches, including breaches by computer hackers, cyber-terrorists and/or unauthorized access to or disclosure of our and/or our employees’ or customers’ data. Furthermore, such unauthorized access or cyber attacks could go unnoticed for some period of time.
These events, among others, could cause system interruptions, delays and/or the loss or release of critical or sensitive data, including the unintentional disclosure of customer, employee or our information, and could delay or prevent operations, including the processing of transactions and reporting of financial results or cause processing inefficiency or downtime, all of which could have a material adverse effect on our business, results of operations and financial condition and could harm our reputation and/or result in significant costs, fines or litigation. Similar risks could affect our customers, subcontractors or suppliers, indirectly affecting us.
While we have security, internal control and technology measures in place to protect our systems and network, if these measures fail as a result of a cyber-attack, other third-party action, employee error, malfeasance or other security failure, and someone obtains unauthorized access to our or our employees’ or customers’ information, our reputation could be damaged, our business may suffer and we could incur significant liability, or, in some cases, we may lose access to our business data. In the ordinary course of business, we have been targeted by malicious cyber-attacks, although our systems have been sufficiently resilient to prevent disruption of our operations; however, because the techniques used to obtain unauthorized access or sabotage systems change frequently and generally are not identified until they are launched against a target, our current or future defenses may not be adequate to protect against new or revised techniques. As a result, we may be required to expend significant resources to protect against the threat of system disruptions and security breaches or to alleviate problems caused by these disruptions and breaches. Any of these events could damage our reputation and have a material adverse effect on our business, results of operations, financial condition and cash flows. Furthermore, while we maintain insurance policies that we consider to be adequate, our coverage may not specifically cover all types of losses or claims that may arise.
In addition, the unauthorized disclosure of confidential information and current and future laws and regulations governing data privacy, including the California Consumer Privacy Act and the European Union’s General Data Protection Regulation, may pose complex compliance challenges and/or result in additional costs. A failure to comply with such laws and regulations could result in penalties, fines and/or legal liabilities and/or harm our reputation. The continuing and evolving threat of cyber attacks has also resulted in increased regulatory focus on risk management and prevention. New cyber-related regulations or other requirements could require significant additional resources and/or cause us to incur significant costs, which could have an adverse effect on our results of operations and cash flows.
We regularly evaluate the need to upgrade and/or replace our systems and network infrastructure to protect our information technology environment, to stay current on vendor supported products and to improve the efficiency and scope of our systems and information technology capabilities. The implementation of new systems and information technology could adversely impact our operations by requiring substantial capital expenditures, diverting management’s attention, and/or causing delays or difficulties in transitioning to new systems. In addition, our system implementations may not result in productivity improvements at the levels anticipated. System implementation disruptions and/or any other information technology disruptions, if not anticipated and appropriately mitigated, could have an adverse effect on our business.
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, results of operations and cash flows.
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, liquidated damages, consequential damages, punitive damages and civil penalties or other losses, or injunctive or declaratory relief. We may also be subject to litigation in the normal course of business 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 joint venture partners, equity investments, customers or other third parties.

18



Claimants may seek large damage awards and defending claims can involve significant costs. When appropriate, we establish accruals for litigation and contingencies that we believe to be adequate in light of current information, legal advice and our indemnity insurance coverages. We reassess our potential liability for litigation and contingencies as additional information becomes available and adjust our accruals as necessary. We could experience a reduction in our profitability and liquidity if we do not properly estimate the amount of required accruals for litigation or contingencies, or if our insurance coverage proves to be inadequate or becomes unavailable, or if 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 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 from 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, results of operations or financial condition.
Our business is subject to operational and physical hazards that could result in substantial liabilities and weaken our financial condition.
Our business is subject to operational hazards due to the nature of services we provide and the conditions in which we operate, including electricity, fires, explosions, mechanical failures and weather-related incidents. Construction projects undertaken by us expose our employees to electrical lines, pipelines carrying potentially explosive or toxic materials, heavy equipment, transportation accidents, adverse weather conditions and the risk of damage to equipment and property. These hazards, among others, 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 or obtaining new contracts, and certain existing contracts could be terminated. Our safety processes and procedures are monitored by various agencies and ratings bureaus. The occurrence of accidents in the course of our business could result in significant liabilities, employee turnover, an 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 revenue, profitability and liquidity.
Our failure to comply with the regulations of OSHA, the U.S. DOT and other state and local agencies that oversee transportation and safety compliance could reduce our revenue, profitability and liquidity.
OSHA 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 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 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.
Our service activities involve a high degree of operational risk, and while we invest substantial resources in occupational health and safety programs, 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 and fatalities in the past, and may suffer additional injuries or fatalities 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 liquidity, cash flows and results of operations. From time to time, we have received notice from the DOT that our motor carrier operations will be monitored and that the failure to improve our safety performance could result in suspension or revocation of vehicle registration privileges. If we were not able to successfully resolve such issues, our ability to service our customers could be damaged, which could lead to a material adverse effect on our results of operations, cash flows and liquidity.
We are subject to risks associated with climate change.
In recent years, there has been an increased focus on climate change, greenhouse gas and other emissions and other potential damage to the environment caused by human activities. The potential effects of climate change on our operations is highly uncertain. Climate change may result in, among other things, an increase in extreme weather events, such as floods, hurricanes, wildfires, rising sea levels and limitations on water availability and quality. Extreme weather conditions could limit the availability of resources, increase the costs of our projects, or could cause projects to be delayed or canceled. Our operating results are significantly influenced by weather. Therefore, major changes in weather patterns could have a significant effect on our future operating results. For example, if climate change results in a significant increase in adverse weather conditions in a given period, we could experience reduced productivity, which could negatively affect our revenue and profitability. Climate change could also affect our customers and the projects they award. Demand for power projects, underground pipelines or other projects could be negatively affected by significant changes in weather or from legislation or regulations governing climate change. Additionally, legislative and/or regulatory responses related to climate change could affect the availability of goods, increase our costs or otherwise negatively affect our operations. Reductions in project awards, increases in costs related to climate change and climate change regulations could have a material adverse effect on our results of operations, cash flows and liquidity.
The renewable energy industry is partially reliant on tax incentives, the availability of which may be uncertain and could adversely affect demand for our services.
The renewable energy industry has historically been reliant on tax incentives, which have spurred investment in renewable energy facilities. These tax incentives typically have a finite duration, creating uncertainty for developers of renewable energy facilities, which may adversely affect investment in them and, accordingly, demand for our services. We cannot predict the effect that current or future tax incentive legislation and/or expiration or extension of these incentives will have on demand for our services. Currently, there are certain federal tax incentives applicable to renewable energy projects, which are expected to be phased out beginning in 2021. In order to qualify for these tax credits, construction must begin before the end of 2020 and the project must be placed in service prior to the end of 2024. Any future efforts to extend or renew the existing tax incentives are uncertain,

19



and if extended or renewed, the provisions related to such extensions or renewals may not be as favorable as those that currently exist, which could materially and adversely affect demand for our services, results of operations, cash flows and liquidity.
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, 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 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, many of whom have extensive industry experience, and is dependent upon retaining and recruiting qualified management to execute our business strategy. Labor shortages, increased labor or training costs, or the loss of key personnel could materially adversely affect our results of operations, cash flows and liquidity.
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 could have a material adverse effect on our results of operations, cash flows and liquidity.
We depend on subcontractors to perform work for some of our projects. There is a risk that we could have disputes with subcontractors arising from, among other things, the quality and timeliness of the work they perform, customer concerns, or our failure to extend existing work orders or issue new work orders under a subcontracting arrangement. If any of our subcontractors fail to perform the agreed-upon services on a timely basis and/or deliver the agreed-upon supplies, our ability to fulfill our obligations as a prime contractor could 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. Additionally, 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 us, or delay paying us, for the related work. 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, equipment manufacturer or lessor, any substantial limitation on the availability of suppliers or equipment, including from economic or market conditions, could negatively affect our operations. If we cannot acquire sufficient materials or equipment, it could materially and adversely affect our results of operations, cash flows and liquidity.
Our participation in strategic arrangements, including joint ventures and equity investments, exposes us to numerous risks.
We have certain strategic arrangements, including joint ventures and equity investments, which provide us the opportunity to combine our skills and resources with those of others to allow for the performance of particular projects for which we do not control the day-to-day operations. The success of these arrangements depends, in large part, on whether our partners satisfy their contractual and performance obligations. In certain of these arrangements, we and our partners are jointly and severally liable for liabilities and obligations of the entity or joint venture. If one of our partners fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming from claims or lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate share of a liability to make up for our partner’s shortfall. Further, if we are unable to adequately address our partner’s performance issues, the projects could be terminated, which could result in legal liability, harm our reputation and/or impair our ability to participate in future investment and project opportunities, all of which could materially adversely affect our results of operations, cash flows and liquidity. In the past, we have incurred losses from our equity investments. We also could be subject to a write-down of a portion or all of the net investment related to such arrangements. Market or other conditions, such as the inability of an entity in which we have invested to complete certain transactions, could subject us to a loss of some or all of the value of our investment. See Note 14 - Commitments and Contingencies and Note 4 - Fair Value of Financial Instruments in the notes to the audited consolidated financial statements, which are incorporated by reference, for additional information.
We may have additional tax liabilities associated with our domestic and international operations.
We are subject to income taxes in the United States and certain foreign jurisdictions. 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 are dynamic and subject to change as new laws are passed and new interpretations of laws are issued or applied, and such changes could materially affect our tax provisions. The U.S. enacted tax reform legislation in 2017, referred to as the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). The provisions of the 2017 Tax Act require significant judgments and estimates to be made, and our interpretations of these provisions could differ from those of the U.S. Treasury Department or the Internal Revenue Service (the “IRS”), as many provisions of the 2017 Tax Act still do not have final guidance. In addition, we are audited by various U.S. and foreign 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. Although we believe that our tax estimates are reasonable, the final outcome of income tax examinations could be materially different from our expectations and the estimates that are reflected in our consolidated financial statements, which could have a material adverse effect on our results of operations, cash flows and liquidity.
We are self-insured against many potential liabilities.
Although we are effectively self-insured for substantially all claims because most claims against us do not exceed the deductibles under our insurance policies, there can be no assurance that our insurance coverages will be sufficient under all circumstances, or against all claims or liabilities to which we may be subject. We actuarially determine any liabilities for unpaid claims and associated expenses, including losses incurred but not reported, and reflect the present value of those liabilities on our balance sheet. The determination of such claims and expenses and the appropriateness of the related liability is reviewed and updated quarterly. However, insurance liabilities are difficult to assess and estimate due to many factors, the

20



effects of which are often unknown or difficult to estimate, including the severity of an injury, the determination of our liability in proportion to other parties’ liability, the number of incidents not reported and the effectiveness of our safety programs. If our insurance costs exceed our estimates of insurance liabilities, or if our insurance claims increase, or if our insurance coverage proves to be inadequate or becomes unavailable, we could experience increased exposure to risk and/or a decline in profitability and liquidity.
Changes to renewable portfolio standards and decreased demand for renewable energy projects could negatively affect our results of operations, cash flows and liquidity.
We build renewable energy infrastructure, including wind, solar and other renewable energy facilities. The development of renewable energy facilities is dependent upon federal tax credits, the existence of renewable portfolio standards and other tax or state incentives. Renewable portfolio standards are state specific statutory provisions requiring that electric utilities generate a certain amount of electricity from renewable energy sources or devote a certain portion of operational/development capacity to renewable energy sources. Additionally, certified renewable energy generators earn certificates for every megawatt hour of electricity they produce and can sell these along with their electricity to their customers. In the past, these standards have spurred growth in the renewable energy industry and demand for renewable energy infrastructure construction services. Renewable energy project revenue, however, has been, and in the future is expected to continue to be, highly volatile. Renewable portfolio standards or goals have been adopted in many states. Elimination of, or changes to, existing renewable portfolio standards or similar environmental policies could negatively affect demand for our services. Additionally, renewable energy can be more expensive to produce and may require additional power generation sources as backup. The locations of renewable energy projects are often remote and not viable unless connection to the grid is economically feasible. Furthermore, funding for renewable energy initiatives may not be available, particularly during periods of tight credit markets. These factors could result in fewer renewable energy projects than anticipated or a delay in the timing of construction of these projects and the related infrastructure, which would negatively affect demand for our services.
Warranty claims resulting from our services could have a material adverse effect on our business.
We generally warrant the work we perform for a one- to two-year period following substantial completion of a project, subject to further extensions of the warranty period following repairs or replacements. Warranty claims have historically not been material, but such claims could potentially increase. If warranty claims occur, we could be required to repair or replace warrantied items, 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 could 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.
Certain of our businesses have employees who are represented by unions or are subject to collective bargaining agreements. The use of a unionized workforce and any related obligations could adversely affect our operations.
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 that could affect their members. Therefore, we cannot assure you 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 liquidity, cash flows and results of operations.
Our participation in multiemployer pension plans may subject us to liabilities that could materially and adversely affect our liquidity, cash flows and results of operations.
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 multiemployer pension plans are underfunded, the Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980 (collectively, “ERISA”), may subject us to substantial liabilities in the event of a complete or partial withdrawal from, or upon termination of, such plans. 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. In addition, the Pension Protection Act of 2006, as amended, requires pension plans that are underfunded to 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 may impose on the employers contributing to such plans 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, 2019, 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, or increased contributions on underfunded plans. The amount we may be obligated to pay or 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. We do not have plans to withdraw from, and are not aware of circumstances that would reasonably lead to material claims against us in connection with the multiemployer pension plans in which we participate. There can be no assurance, however, that we will not be assessed liabilities in the future. 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 affect our cash flows, liquidity and results of operations.

21



Our existing operations in international markets, or expanding into additional international markets, may not be successful and could expose us to risks, including failure to comply with the U.S. Foreign Corrupt Practices Act and/or similar anti-bribery laws, which could harm our business and prospects.
We derive a portion of our revenue from international markets, and we may further expand the volume of international services we provide, as well as the foreign geographic territories in which we operate. See Note 13 - Segments and Related Information in the notes to the audited consolidated financial statements, which is incorporated by reference, for foreign revenue information. Our foreign operations are presently conducted primarily in Canada, but we have performed work in various other foreign countries, and the revenue we derive from, or the number of countries in which we operate, could expand in the future. Economic conditions, including those resulting from wars, geopolitical shifts, civil unrest, acts of terrorism and other conflicts, or volatility in the global markets could adversely affect our foreign customers, their demand for our services and/or their ability to pay for our services. In addition, there are numerous risks inherent in conducting business internationally, including, but not limited to, potential instability in international markets, changes in regulatory requirements applicable to international operations, including evolving consumer protection and data use and security standards, foreign currency fluctuations, exchange controls and other limits on our ability to repatriate and reinvest earnings, political, economic and social conditions in foreign countries, tariffs and duties, and complex U.S. and foreign laws and treaties, including taxation laws and the U.S. Foreign Corrupt Practices Act (the “FCPA”). These risks could restrict our ability to provide services to foreign customers or to operate our international businesses profitably, and our overall business and results of operations could be negatively affected by our foreign activities.
The FCPA and similar anti-bribery laws in other jurisdictions prohibit U.S.-based companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. We pursue opportunities in certain parts of the world that experience corruption to some degree, and, in certain circumstances, compliance with anti-bribery laws may conflict with local customs and practices. Our policies mandate compliance with these anti-bribery laws. Further our subcontractors, agents and others who work for us or on our behalf are expected to comply with the FCPA and other anti-bribery laws. There is no assurance that our employees and agents will comply with the FCPA, or that anti-bribery laws will protect us against liability under the FCPA or other laws for actions taken by our agents, employees and/or intermediaries. If we are found to be liable for FCPA violations, either due to our own acts or our inadvertence, or due to the acts or inadvertence of others, we could incur severe criminal or civil penalties or other sanctions, which could have a material adverse effect on our reputation, business, results of operations or cash flows. In addition, detecting, investigating and resolving actual or alleged FCPA violations is expensive and can consume significant time and attention of our senior management.
We are subject to foreign exchange and currency risks that could adversely affect our operations and our ability to reinvest earnings from operations. In addition, our ability to mitigate our foreign exchange risk through hedging transactions may be limited.
We generally attempt to denominate our contracts in U.S. dollars or in the currencies of our costs. We have, and could in the future enter into contracts or service arrangements in foreign locations that are denominated in currencies other than the U.S. dollar, subjecting us to currency risk exposure, particularly when the contract revenue is denominated in a currency different from the contract costs. Certain portions of our consolidated revenue and operating expenses are in foreign currencies. As a result, we are subject to foreign currency risks, including risks resulting from changes in foreign exchange rates and limitations on our ability to reinvest earnings from operations in one country to fund the financing requirements of our operations in other countries.
Our credit facility and senior notes impose 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 default and covenants that prohibit us from taking certain actions without satisfying certain financial tests or obtaining the consent of the lenders, including, among other things:
making investments and acquisitions in excess of specified amounts;
incurring additional indebtedness in excess of specified amounts;
repurchasing shares or paying dividends in excess of specified amounts;
creating certain liens against our assets;
prepaying subordinated indebtedness;
engaging in certain mergers or combinations; and
engaging in transactions that would result in a “change of control,” as defined in the credit facility and the indentures governing our senior notes.
Our senior secured credit facility requires that we comply with a consolidated leverage ratio and a consolidated interest coverage 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 or under the indentures relating to our senior notes. In addition, these covenants may prevent us from engaging in transactions that benefit us, including responding to changing business and economic conditions or securing additional financing, if needed. Our business is capital intensive and to the extent we need additional financing, we may not be able to obtain such financing at all or on favorable terms, which could materially decrease our profitability, cash flows and liquidity.
Regulatory changes and/or reforms, such as the phase-out of the London Inter-bank Offered Rate (“LIBOR”), which is expected to occur by 2021, could lead to additional volatility in interest rates for our variable rate debt and other unpredictable effects. While our material financing arrangements indexed to LIBOR have procedures for determining an alternative base rate, such alternative base rate could perform differently than the current LIBOR-indexed rate and could result in an increase in the cost of our variable rate indebtedness, which could negatively affect our results of operations and cash flows.

22



We may be unable to obtain sufficient bonding capacity to support certain service offerings, and the need for performance and surety bonds could reduce availability under our 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 in connection with the bonds, which would reduce availability under our credit 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 as a condition to issuing or renewing any bonds. 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 projects that require bonding.
A failure of our internal control over financial reporting could materially affect our business.
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. An internal control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.  Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Internal control over financial reporting may not prevent or detect misstatements due to inherent limitations in internal control systems. Any failure to maintain an effective system of internal control over financial reporting could limit our ability to report our financial results accurately and timely or to detect and prevent fraud, and could expose us to litigation, harm our reputation, and/or adversely affect the market price of our common stock.
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. For 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 dilute our earnings per share as well as our existing shareholders’ individual ownership percentages and could lead to volatility in our common stock price. Our Amended and Restated Articles of Incorporation provide that we may issue up to a total 145.0 million shares of common stock, of which approximately 76.6 million shares were outstanding as of December 31, 2019.
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.
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;
increasing interest expense on variable rate indebtedness, 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

23



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.
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 New York Stock Exchange 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 and fuel 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;
announcements of share repurchase programs, or repurchases of our common stock under existing repurchase programs; and
sales of our common stock or other securities, including any shares issued in connection with business acquisitions or earn-out obligations for any past or future acquisitions.
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.
A small number of our existing shareholders have the ability to influence major corporate decisions.
Jorge Mas, our Chairman, and José R. Mas, our Chief Executive Officer, beneficially owned approximately 23% of the outstanding shares of our common stock as of December 31, 2019. Accordingly, they are in a position to influence:
the vote of most matters submitted to our shareholders, including any merger, consolidation or sale of all or substantially all of our assets;
the nomination of individuals to our Board of Directors; and
a change in our control.
These factors may discourage, delay or prevent a takeover attempt that shareholders might consider in their best interests or that might result in shareholders receiving a premium for their common stock.
Our articles of incorporation and certain provisions of Florida law contain anti-takeover provisions that may make it more difficult to effect a change in our control.
Certain provisions of our articles of incorporation, by-laws and the Florida Business Corporation Act could delay or prevent an acquisition or change in control and the replacement of our incumbent directors and management, even if doing so might be beneficial to our shareholders by providing them with the opportunity to sell their shares possibly at a premium over the then market price of our common stock. For example, our Board of Directors is divided into three classes. At any annual meeting of our shareholders, our shareholders only have the right to appoint approximately one-third of the directors on our Board of Directors. Consequently, it will take at least two annual shareholder meetings to effect a change in control of our Board of Directors, which may discourage hostile takeover bids. In addition, our articles of incorporation authorize our Board of Directors, without further shareholder approval, to issue preferred stock. The issuance of preferred stock could also dilute the voting power of holders of our common stock, including the granting of voting control to others, which could delay or prevent an acquisition or change in control.

MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES
Market Information
Our common stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “MTZ.”
Holders. As of February 24, 2020, there were 1,704 holders of record of our common stock. In calculating the number of shareholders, we consider clearing agencies and security position listings as one shareholder for each agency or listing.
Dividends. We have historically not paid cash dividends and do not currently anticipate paying a cash dividend. We intend to retain future earnings for reinvestment. Our Board of Directors will make any future determination as to the payment of dividends at its discretion, and this determination will depend upon our operating results, financial condition and capital requirements, general business conditions and such other factors that the Board of Directors considers relevant. In addition, our credit agreements prohibit us from paying cash dividends or making other distributions of our common stock without prior consent of the lender. The indenture governing our senior notes also contains covenants that restrict our ability to make certain payments including the payment of dividends. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Financial Condition, Liquidity and Capital Resources.”
Issuer Purchases of Equity Securities. During the year ended December 31, 2019, we repurchased a total of 15,100 shares of our common stock under our share repurchase programs. See Note 11 - Equity, which is incorporated by reference, for additional information pertaining to our share repurchase programs.

ITEM 7.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our business, financial condition and results of operations should be read in conjunction with our audited consolidated financial statements and notes thereto in Item 8 of this Form 10-K. The discussion below contains forward-looking statements that are based upon our current expectations and is subject to uncertainty and changes in circumstances. Actual results may differ materially from these expectations due to inaccurate assumptions and known or unknown risks and uncertainties, including those identified in “Cautionary Statement Regarding Forward-Looking Statements” and Item 1A. “Risk Factors.”
Business
See Item 1. “Business” for discussion pertaining to our business and reportable segments.
Recent acquisitions. During the year ended December 31, 2019, we completed six acquisitions, one of which specializes in water infrastructure for pipeline companies and is included within our Oil and Gas segment, four of which are included within our Communications segment, including a wireline/fiber deployment construction contractor and a telecommunications company specializing in a broad range of end-to-end wireless telecommunications solutions, and one of which specializes in construction projects in the power industry and is included in our Power Generation and Industrial segment. During the year ended December 31, 2018, we completed two acquisitions, including a construction management firm specializing in steel building systems and a wind turbine services company, both of which are included in our Power Generation and Industrial segment. For additional information, see Note 3 - Goodwill and Other Intangible Assets in the notes to the audited consolidated financial statements, which is incorporated by reference.
Economic, Industry and Market Factors
We closely monitor the effects of changes in economic and market conditions on our customers. General economic and market conditions can negatively affect demand for our customers’ products and services, which can affect our customers’ planned capital and maintenance budgets in certain end-markets. Market, regulatory and industry factors could affect demand for our services, including (i) changes to our customers’ capital spending plans; (ii) new or changing regulatory requirements or other governmental policy changes or uncertainty; (iii) economic, market or political developments; (iv) mergers and acquisitions among the customers we serve; (v) changes in technology, tax and other incentives; and (v) access to capital for customers in the industries we serve. Availability of transportation and transmission capacity and fluctuations in market prices for oil, gas and other fuel sources can also affect demand for our services, in particular, on pipeline and power generation construction services. These fluctuations, as well

27



as the highly competitive nature of our industry, can result in lower bids and lower profit on the services we provide. In the face of increased pricing pressure or other market developments, we strive to maintain our profit margins through productivity improvements, cost reduction programs and/or business streamlining efforts. 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 may be unable to fully mitigate, or benefit from, such changes.
Effect of Seasonality and Cyclical Nature of Business
Our revenue and results of operations can be subject to seasonal and other variations. These variations are influenced by weather, customer spending patterns, bidding seasons, project schedules, holidays and timing, in particular, for large, non-recurring projects. Typically, our revenue is lowest at the beginning of the year and during the winter months because cold, snowy or wet conditions cause project delays. Revenue is generally higher during the summer and fall months due to increased demand for our services when favorable weather conditions exist in many of the regions in which we operate, but continued cold and wet weather can often affect second quarter productivity. In the fourth quarter, many projects tend to be completed by customers seeking to spend their capital budgets before the end of the year, which generally has a positive effect on our revenue. However, the holiday season and inclement weather can cause delays, which can reduce revenue and increase costs on affected projects. Any quarter may be positively or negatively affected by adverse or unusual weather patterns, including warm winter weather, excessive rainfall, flooding or natural catastrophes such as hurricanes or other severe weather, making it difficult to predict quarterly revenue and margin variations.
Additionally, our industry can be highly cyclical. Fluctuations in end-user demand within the industries we serve, or in the supply of services within those industries, can affect 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 quarter, even if not for the full year. In addition, revenue from master service and other 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/other arrangements can also materially affect quarterly results in a given period. Accordingly, our operating results in any particular period may not be indicative of the results that can be expected for any other period.
Understanding Our Results of Operations
Revenue. We provide engineering, building, installation, maintenance and upgrade services to our customers. We derive revenue from projects performed under master and other service agreements as well as from contracts for specific projects requiring the construction and installation of an entire infrastructure system or specified units within an infrastructure system. See Item 1. “Business” for discussion of our business and revenue-generating activities and “Comparison of Fiscal Year Results” below for revenue results by reportable segment.
Costs of Revenue, Excluding Depreciation and Amortization. Costs of revenue, excluding depreciation and amortization, consists principally of salaries, employee incentives and benefits, subcontracted services, equipment rentals and repairs, fuel and other equipment expenses, material costs, parts and supplies, insurance and facilities expenses. Project profit is calculated by subtracting a project’s costs of revenue, including project-related depreciation, from project revenue. Project profitability and corresponding project margins will generally be reduced if actual costs to complete a project exceed our project cost estimates. Estimated losses on contracts, or the excess of estimated costs to complete a contract over the contract’s remaining revenue, are recognized in the period in which such losses are determined. Factors impacting our costs of revenue, excluding depreciation and amortization, include:
Project Mix. The mix of revenue derived from the projects we perform impacts overall project margins, as margin opportunities can vary by project. For example, installation work, which is often performed on a fixed price basis, has a higher level of margin risk than maintenance or upgrade work, which is often performed under pre-established or time and materials pricing arrangements. As a result, changes in project mix between installation work and maintenance or upgrade services can affect our project margins in a given period. Our project mix by industry can also affect our overall margins, as project margins can vary by industry and over time.
Seasonality, Weather and Geographic Mix. Seasonal patterns, which can be affected by weather conditions, can have a significant effect on project margins. Adverse or favorable weather conditions can affect project margins in a given period. For example, extended periods of rain or snowfall can negatively affect revenue and project margins due to reduced productivity from projects being delayed or temporarily halted. Conversely, when weather remains dry and temperatures are accommodating, more work can be done, sometimes with less cost, which can favorably affect project margins. In addition, the mix of business conducted in different geographic areas can affect project margins due to the particular characteristics of the physical locations where work is being performed, such as mountainous or rocky terrain versus open terrain. Site conditions, including unforeseen underground conditions, can also affect project margins.
Price and Performance Risk. Overall project margins may fluctuate due to project pricing, changes in the cost of labor and materials, job productivity and work volume. Job productivity can be affected by quality of the work crew and equipment, the quality of engineering specifications and designs, availability of skilled labor, environmental or regulatory factors, customer decisions or delays 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 has physical obstructions or legal encumbrances.
Subcontracted Resources. Our use of subcontracted resources in a given period is dependent upon activity levels and the amount and location of existing in-house resources and capacity. Project margins on subcontracted work can vary from those on self-perform work. As a result, changes in the mix of subcontracted resources versus self-perform work can affect our overall project margins.
Material versus Labor Costs. In many cases, our customers are responsible for supplying their own materials on projects; however, under certain contracts, we may agree to provide all or part of the required materials. Project margins are typically lower on projects where we furnish a significant amount of materials due to the fact that margins on materials are generally lower than margins on labor costs. Therefore, increases in the percentage of work with significant materials requirements could decrease our overall project margins.

28



General and Administrative Expense. General and administrative expenses consist principally of compensation and benefit expenses, travel expenses and related costs for our finance, benefits, insurance and risk management, legal, facilities, information technology services and executive functions. General and administrative expenses also include non-cash stock-based compensation expense, outside professional and accounting fees, expenses associated with information technology used in administration of the business, acquisition costs, including those related to acquisition integration, and certain restructuring charges.
Interest Expense, Net. Interest expense, net, consists of contractual interest expense on outstanding debt obligations, amortization of deferred financing costs and other interest expense, including interest expense related to financing arrangements. Interest expense is offset, in part, by interest earned on cash and other investments.
Other Income or Expense. Other income or expense consists primarily of gains or losses from sales, disposals of, or changes in estimated recoveries from assets and investments, certain legal/other settlements, gains or losses from changes to estimated earn-out accruals and certain purchase accounting adjustments.
Financial Performance Metrics
Our senior management team regularly reviews certain key financial performance metrics within our business, including:
revenue and profitability on an overall basis, by reportable segment and for selected projects;
revenue by customer and by contract type;
costs of revenue, excluding depreciation and amortization; general and administrative expenses; depreciation and amortization; interest expense, net; other income or expense; and provision for income taxes;
earnings before interest, taxes, depreciation and amortization (“EBITDA”) and adjusted EBITDA, which is EBITDA excluding certain items that may not be indicative of our core operating results, as well as items that can vary widely across different industries or among companies within the same industry. See discussion of our non-U.S. GAAP financial measures following the “Comparison of Fiscal Year Results” section below;
earnings per share and adjusted earnings per share, as defined in our non-U.S. GAAP financial measures discussion;
days sales outstanding, net of deferred revenue; and days payable outstanding;
interest and debt service coverage ratios; and
liquidity and cash flows.
Management’s analysis includes detailed discussions of proposed investments in new business opportunities or property and equipment, productivity improvement efforts, acquisition integration efforts, strategic arrangement opportunities and working capital and other capital management efforts. Measuring these key performance indicators is an important tool used by management to make informed and timely operational decisions, which we believe can help us improve our performance.
Critical Accounting Estimates
This discussion and analysis of our financial condition and results of operations is based upon our audited consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires the use of estimates and assumptions that affect the amounts reported in our audited 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 our operating results, including the results of construction contracts accounted for under the cost-to-cost method, and 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. Our accounting policies and critical accounting estimates are reviewed periodically by the Audit Committee of the Board of Directors.
We believe that our accounting estimates pertaining to: 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 construction contracts accounted for under the cost-to-cost method, for which the recorded amounts require estimates of costs to complete and the amount and probability of variable consideration included in the contract transaction price; fair value estimates, including those related to acquisitions, valuations of goodwill, indefinite-lived intangible assets and acquisition-related contingent consideration; income taxes; self-insurance liabilities; and litigation and other contingencies, 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. Actual results could, however, vary materially from these accounting estimates. Refer to Note 1 - Business, Basis of Presentation and Significant Accounting Policies in the notes to the audited consolidated financial statements, which is incorporated by reference, for discussion of our significant accounting policies.
Revenue Recognition
We recognize revenue from contracts with customers under Accounting Standards Codification (“ASC”) Topic 606 (“Topic 606”). Under Topic 606, revenue is recognized when, or as, control of promised goods and services is transferred to customers, and the amount of revenue recognized reflects the consideration to which an entity expects to be entitled in exchange for the goods and services transferred. We primarily recognize revenue over time utilizing the cost-to-cost measure of progress on contracts for specific projects and for certain master service and other service agreements.

29



Contracts. We derive revenue primarily from construction projects performed under: (i) master and other service agreements, which provide a menu of available services in a specific geographic territory that are utilized on an as-needed basis, and are typically priced using either a time and materials or a fixed price per unit basis; and (ii) contracts for specific projects requiring the construction and installation of an entire infrastructure system or specified units within an infrastructure system, which are subject to multiple pricing options, including fixed price, unit price, time and materials, or cost plus a markup.
The total contract transaction price and cost estimation processes used for recognizing revenue over time under the cost-to-cost method is based on the professional knowledge and experience of our project managers, engineers and financial professionals. 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 consideration are factors that influence estimates of the total contract transaction price, total costs to complete those contracts and our profit recognition. Changes in these factors could result in revisions to revenue in the period in which the revisions are determined, which could materially affect our consolidated results of operations for that period. Provisions for losses on uncompleted contracts are recorded in the period in which such losses are determined. For the year ended December 31, 2019, project profit was affected by less than 5% as a result of changes in contract estimates included in projects that were in process as of December 31, 2018. Revenue recognized for the year ended December 31, 2019 as a result of changes in total contract transaction price estimates, including from variable consideration, from performance obligations satisfied or partially satisfied in prior periods, totaled approximately $58.3 million.
Performance Obligations. A performance obligation is a contractual promise to transfer a distinct good or service to a customer, and is the unit of account under Topic 606. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied. Our contracts often require significant services to integrate complex activities and equipment into a single deliverable, and are therefore generally accounted for as a single performance obligation, even when delivering multiple distinct services. Contract amendments and change orders, which are generally not distinct from the existing contract, are typically accounted for as a modification of the existing contract and performance obligation. The vast majority of our 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, management 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 one, or more than one, performance obligation. This evaluation requires significant judgment and is based on the facts and circumstances of the various contracts.
Variable Consideration. Transaction prices for our contracts may include variable consideration, which comprises items such as change orders, claims and incentives. Management estimates variable consideration for a performance obligation utilizing estimation methods that we believe best predict the amount of consideration to which we will be entitled. Variable consideration is included in the estimated transaction price if it is probable that when the uncertainty associated with the variable consideration is resolved, there will not be a significant reversal of the cumulative amount of revenue that has been recognized. Management’s estimates of variable consideration and the determination of whether to include estimated amounts in transaction prices are based largely on engineering studies and legal opinions, past practices with the customer, specific discussions, correspondence or preliminary negotiations with the customer and all other relevant information that is reasonably available at the time of the estimate. The effect of variable consideration on the transaction price of a performance obligation is typically recognized as an adjustment to revenue on a cumulative catch-up basis, as such variable consideration, which typically pertains to changed conditions and scope, is generally for services encompassed under the existing contract. To the extent unapproved change orders, claims and other variable consideration reflected in transaction prices are not resolved in our favor, or to the extent incentives reflected in transaction prices are not earned, there could be reductions in, or reversals of, previously recognized revenue.
As of December 31, 2019, we included approximately $27 million of change orders and/or claims in transaction prices for certain contracts that were in the process of being resolved in the ordinary course of business, including through negotiation, arbitration and other proceedings. These transaction price adjustments, when earned, are included within contract assets or accounts receivable, net of allowance, as appropriate. As of December 31, 2019, these change orders and/or claims were primarily related to certain projects in our Oil and Gas segment. We actively engage with our customers to complete the final approval process, and generally expect these processes to be completed within one year. Amounts ultimately realized upon final agreement by customers could be higher or lower than such estimated amounts.
Business Combinations
The determination of the fair value of net assets acquired in a business combination and estimates of acquisition-related contingent consideration, which, for our acquisitions are primarily “earn-out” liabilities, requires estimates and judgments of future cash flow expectations for the acquired business and the related identifiable tangible and intangible assets. Fair values of net assets acquired are calculated using expected cash flows and industry-standard valuation techniques. Fair values of earn-out liabilities are estimated using income approaches such as discounted cash flows or option pricing models.
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. Other revisions to these fair value estimates are reflected as income or expense, as appropriate. For the year ended December 31, 2019, the effect of other fair value adjustments for acquisitions was a net expense of $51 million and related to earn-out arrangements.
Significant changes in the assumptions or estimates used in the underlying valuations, including the expected profitability or cash flows of an acquired business, could materially affect our operating results in the period such changes are recognized.
Goodwill and Indefinite-Lived Intangible Assets
We have goodwill and indefinite-lived intangible assets that have been recorded in connection with our acquisitions of businesses. Goodwill

30



and indefinite-lived intangible assets are not amortized, but instead are tested for impairment at least annually. We perform our annual impairment tests of goodwill and indefinite-lived intangible assets during the fourth quarter of each year, and on a quarterly basis, we monitor these assets for potential indicators of impairment. Goodwill is required to be tested for impairment at the reporting unit level. A reporting unit is an operating segment, or one level below the operating segment, which is referred to as a component. We combine all of the components of our Electrical Transmission operating segment into one reporting unit and combine two of the components within our Power Generation and Industrial operating segment into one reporting unit. All of our other components each comprise one reporting unit.

For the year ended December 31, 2019, we performed a qualitative assessment for our goodwill and indefinite-lived intangible assets by examining relevant events and circumstances that could have an effect on their fair values, 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 the results of the qualitative assessments for the year ended December 31, 2019, we performed quantitative testing for (i) three reporting units within our Oil and Gas operating segment and (ii) one reporting unit in the Communications segment. We also performed quantitative testing during 2019 for an indefinite-lived pre-qualification intangible asset in our Oil and Gas operating segment. Factors considered by management in determining the reporting units and indefinite-lived pre-qualification intangible assets for which quantitative assessments were performed included the effects of current or expected changes in market conditions on the future business outlook, success rates on new project awards and levels of operating activity.
For the reporting units for which quantitative testing was performed, we estimated their fair values using a combination of market and income approaches. Under the market approach, fair values were estimated using published market multiples for comparable companies and applying them to revenue and EBITDA. Under the income approach, a discounted cash flow methodology was used, considering: (i) management estimates, such as projections of revenue, operating costs and cash flows, taking into consideration historical and anticipated financial results; (ii) general economic and market conditions; and (iii) the impact of planned business and operational strategies. Estimated discount rates were determined using the weighted average cost of capital for each reporting unit at the time of the analysis, taking into consideration the risks inherent within each reporting unit individually. Significant assumptions used in testing the reporting units included terminal values based on terminal growth rates of 3.0%, five to nine years of discounted cash flows prior to the terminal value, and discount rates ranging from 13.0% to 16.0%. We believe the assumptions used in our quantitative goodwill impairment tests are reflective of the risks inherent in the business models of our reporting units and within our industry.
Based on the results of the quantitative assessment, the estimated fair values of the reporting unit within our Communications operating segment and one of the reporting units within our Oil and Gas operating segment were determined to substantially exceed their carrying values. The remaining two reporting units in our Oil and Gas operating segment, each of which had approximately $15 million of goodwill, had estimated fair values that exceed their respective carrying values by approximately 15.0%. A 100 basis point increase in the discount rate would not have resulted in any of the reporting units’ carrying values exceeding their fair values.
For the indefinite-lived pre-qualification intangible asset for which quantitative testing was performed, we estimated the fair value of the intangible asset using a cost methodology, incorporating estimates of the opportunity cost associated with the asset’s loss based on discounted cash flows over a four-year period. The impairment test incorporated an estimated discount rate of 13.0%. Based on the results of the quantitative assessment, the estimated fair value of the indefinite-lived pre-qualification intangible asset in our Oil and Gas operating segment was determined to be less than its carrying value and a pre-tax, non-cash impairment charge of $3.3 million was recorded for the difference. This indefinite-lived pre-qualification intangible asset had a carrying value of $41.4 million remaining as of December 31, 2019.
As of December 31, 2019, we believe that the recorded balances of goodwill and indefinite-lived intangible assets are recoverable; however, 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 and indefinite-lived intangible asset impairment charges in future periods.

Income Taxes
Our provision for income taxes uses an effective tax rate based on annual pre-tax income, statutory tax rates, permanent tax differences and tax planning opportunities in the various jurisdictions in which we operate. Significant factors that can affect our annual effective tax rate include our assessment of certain tax matters, the location and amount of taxable earnings, changes in certain non-deductible expenses and expected credits. Although we believe our provision for income taxes is correct and the related assumptions are reasonable, the final outcome of tax matters could be materially different from what we currently anticipate, which could result in significant costs or benefits to us. In December 2017, the 2017 Tax Act was enacted, which includes broad tax reform that was applicable to the Company. See Note 12 - Income Taxes in the notes to the audited consolidated financial statements, which is incorporated by reference, for additional discussion.
In the ordinary course of business, there is inherent uncertainty in quantifying income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based on our evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recognized the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in our financial statements.
We file income tax returns in numerous tax jurisdictions, including U.S. federal, most U.S. states and certain foreign jurisdictions. Although we believe our calculations for tax returns are correct and the positions taken thereon are reasonable, the final outcome of income tax examinations could be materially different from our expectations and the estimates that are reflected in our consolidated financial statements, which could have a material effect on our results of operations, cash flows and liquidity.
Self-Insurance
We are self-insured up to the amount of our deductible for our insurance policies. Liabilities under our insurance programs are accrued based upon our estimate of the ultimate liability for claims, with assistance from third-party actuaries. 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 our liability in proportion to other parties and the number of incidents not reported. Accruals are based upon known facts and historical trends. Although we believe such accruals are adequate, a change in experience or actuarial assumptions could materially affect our results of operations in a particular period.
Litigation and Contingencies
Accruals for litigation and contingencies are based on our assessment, including advice of legal counsel, of the expected outcome of litigation or other dispute resolution proceedings and/or the expected resolution of contingencies. 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 on information available at the time of the assessment due to the uncertain nature of such matters. As additional information becomes available, we reassess potential liabilities related to pending claims and litigation and may revise previous estimates, which could materially affect our results of operations in a given period.
2020 Outlook
We expect market opportunities in the following areas, as more fully described in Item 1. Business above:
Opportunities in our Communications Segment. Significant advances in technology and rapid innovation in service offerings to data consumers continue to increase demand for faster and more reliable wireless and wireline/fiber communications network services. As a result of increased usage of mobile devices, combined with advancements in the IoT, the amount of data affecting network traffic is expected to experience significant and accelerating levels of future growth. In response to these growing demands, CSPs are expanding, densifying and optimizing current wireless and wireline/fiber communications network capacity, while initiating a build-out of 5G infrastructure, the next generation of wireless and fixed wireless network capacity. Large scale 5G deployments, which are expected over the next several years, will include additional and improved tower capacity, as well as deployment of numerous higher bandwidth small/micro cells and distributed antenna systems to densify network performance. In addition, nationwide fiber projects in support of 5G technologies, such as Verizon’s ‘One Fiber’ program, continue to expand to support network densification, data capacity and speed. We believe that the initiation of nationwide 5G tower deployments, deployment of small/micro cells, initiation of fiber projects to support 5G, initial deployment and subsequent capacity additions to FirstNetTM, as well as an expected increase in activity levels for various nationwide CSPs subsequent to expected industry merger activity, will lead to significant increases in 5G telecommunications capital expenditures over multiple years.
Leveraging our expertise in home installation and our existing network of technicians, we believe that we will also benefit from opportunities driven by customers seeking to expand their service offerings in the areas of home automation, connected home security monitoring and control, home entertainment offerings and commercial energy management solutions. We believe that opportunities for installation and maintenance of both Smart City and smart home technologies will over time provide our install-to-the-home group opportunities for future growth, providing an offset to declining trends in subscribership for satellite TV.
We believe that we are well-positioned, as one of the largest providers of communications infrastructure services, to substantially benefit from the expected multi-year significant and broad opportunities in the telecommunications market as previously described. These initiatives are expected to drive communications infrastructure investment, as reflected in our strong level of Communications segment backlog as of December 31, 2019.
Opportunities in our Oil and Gas Segment. We are one of the largest pipeline contractors in North America, with a balanced portfolio of service offerings, including union and non-union services, for the construction and maintenance of large diameter (“long-haul”) pipeline, midstream pipeline, gathering lines and related compressor and pumping stations and treatment plants. Demand for pipeline infrastructure and the related level of oil, natural gas and product pipeline construction activity has grown significantly in recent years as technological advances and increasingly cost-effective drilling, completion and production have significantly increased producible North American oil and natural gas reserves. The effect of these advances

32



on oil and gas production activities in North America has also driven changes in the geographic locations of North American energy production. The increase in oil and natural gas production across multiple basins, such as the Permian, Bakken and Marcellus/Utica basins, has led the industry to initiate actions to address ‘takeaway’ capacity issues, whereby more pipeline infrastructure is required to move production to market. As a result, construction of additional pipeline capacity across multiple basins and throughout the U.S. is underway and in plans for future development to improve available distribution and reduce transportation costs.
According to the DOE’s Short-Term Energy Outlook 2020, the U.S., which was already a net exporter of natural gas, also became a net exporter of oil for the first time since the early twentieth century. Additionally, industry reporting indicates that the abundance of low-cost North American natural gas will continue to drive growth of natural gas as a source of lower-carbon power generation, both in the U.S. and abroad. Additionally, in recent years, demand for LNG exports has risen dramatically, driven in part by the easing of certain export regulations, which is expected to drive construction of pipeline infrastructure for the transport of LNG to coastal export facilities in North America.
These trends are expected to continue to drive demand for North American oil and gas production, creating opportunities for new pipeline infrastructure throughout. Significant investment in pipeline infrastructure will be required to move the increased volumes of oil and gas production to refining centers, distribution hubs, LNG export facilities and industrial users throughout North America, as well as to meet demand resulting from the desire to convert the transportation of oil and gas from traditional methods, such as truck and rail transport, to lower cost and safer pipeline infrastructure. In addition to potential opportunities in the U.S., initiatives in Mexico are expected to provide long-term growth opportunities. We anticipate that demand for pipeline infrastructure in North America will provide continued opportunities for years to come, and that our diverse capabilities and expertise will enable us to continue to be a leading service provider in this market. We also believe that future opportunities exist for upgrades to existing pipeline infrastructure, including pipeline integrity and maintenance upgrades, replacement and modernization efforts, including digitization and other technology upgrades and upgrades to address safety regulations.
We believe that the above-mentioned trends will support continued levels of project activity, continuing a multi-year cycle of demand for pipeline construction projects, and that we are well-positioned to benefit from these trends.
Opportunities in our Electrical Transmission Segment. We believe that the nation’s aging electrical grid will continue to require significant ongoing maintenance, upgrade and expansion to continue delivery of reliable and affordable power, as well as to address future grid resiliency and changing energy supply and distribution requirements. Increased investment in electrical infrastructure will be required to address power line congestion and to avoid delivery failure during peak periods, as well as to modernize the grid and strengthen aging infrastructure to withstand weather events, natural disasters and cyber threats. In addition, clean energy production trends are expected to lead to additional electric infrastructure investment, with shifting trends in power generation to cleaner energy sources, such as natural gas and renewables, while older power plants, including coal-fired and nuclear plants are retired or repurposed.
Future demand for electrical transmission and distribution infrastructure is also expected to result from grid resiliency efforts, technological advances, digitization, expected growth in usage of electric/hybrid vehicles, Smart City initiatives and the continued development of electrical power generation from renewable power sources, among others. The expected growth in demand for, and deployment of, electrical power generation from renewable energy sources will require significant investment in transmission lines, as wind and solar power generation resources are typically located in remote areas of the country, far from industrial users and major population centers.  Growth in electrical power generation from renewable sources in the U.S. will require the grid to be updated. We believe significant capital investment in the transmission and distribution system will continue to be required to support these needs. We have proven expertise in handling complex and high voltage electrical transmission projects and believe that we are well-positioned for these opportunities.
Opportunities in our Power Generation and Industrial Segment. Growing concerns with climate change, the desire to reduce greenhouse gas emissions and growing corporate initiatives for smaller, standalone distributed generation facilities, together with certain regulatory and other policy initiatives at the federal, state and municipal levels, have spurred demand for ‘clean’ energy production from sustainable power sources, including environmentally sensitive electrical power production from renewable sources such as wind, solar and biomass. Currently, almost 40 states, as well as the District of Columbia and four territories, have adopted RPS or renewable energy goals to diversify their energy resources, promote domestic energy production and encourage economic development. Renewable energy policies have helped to drive the U.S. market for wind, solar and other renewable energy sources. In addition, growing efforts to address electric grid resiliency are expected to drive growth in renewables, as utilities and their customers increasingly consider renewable microgrids combined with energy storage solutions to support critical facilities. Advancing technologies and improvements in cost and scalability of renewable energy projects are making these energy sources, particularly solar power projects, increasingly competitive. As a result, we expect these trends will continue to drive demand for construction of renewable infrastructure in the coming years.
In addition, we believe that replacement and repowering of existing wind turbines and foundations with next generation, higher efficiency turbines, as well as maintenance of aging wind farms will provide increased opportunities for wind infrastructure projects. Industrial plant construction opportunities exist in a wide variety of industries, including in the renewable energy industry, as power companies explore ways to reduce their carbon footprint. The low price and environmental advantage of cleaner burning natural gas is expected to continue to drive demand for gas-fired electrical generating plants and conversions of coal-fired power plants to natural gas. A wide variety of industries may seek to expand, convert or construct new plants to take advantage of this economical, cleaner, lower cost and lower carbon fuel source. Biofuel and biomass as alternative fuel sources also present opportunities for the renewable energy market. Industrial facilities and power plants in the biofuels/biomass, food processing, natural gas, petroleum and related industries present opportunities as additional domestic energy reserves are produced, transported and processed.
We are one of the leading renewables contractors in North America, with expertise in wind, solar and biomass, as well as industrial and other power plant construction, and expect to benefit from these market trends.
See Item 1 “Business - Industry Trends” for additional information on the outlook for the industries we serve. Our 2020 results could be adversely affected by the matters discussed in the “Cautionary Statement Regarding Forward-Looking Statements,” Item 1A. “Risk Factors” and Item 3. “Legal Proceedings” of this Form 10-K.
