Industry Trends
The industries in which we operate are undergoing significant transformation driven by several broad, long‑term macroeconomic, technological and regulatory developments. These developments include (i) continued expansion in data consumption and the rapid deployment of artificial intelligence (“AI”) applications and data centers; (ii) increasing levels of electrification across commercial, industrial and residential end‑users; (iii) ongoing transition of the U.S. energy mix toward lower‑carbon and renewable resources; and (iv) federal, state and local investment in critical infrastructure, including through programs established under the Infrastructure Investment and Jobs Act (“IIJA”) and the Inflation Reduction Act (“IRA”). Collectively, these factors are expected to continue to result in opportunities across our Communications, Clean Energy and Infrastructure, Power Delivery, and Pipeline Infrastructure segments.
These macro drivers increasingly intersect across industries and we expect will create multi-segment demand aligned with our diversified portfolio of services. Growth in data centers, for example, requires extensive fiber network expansion and wireless densification; necessitates new renewable and conventional energy generation resources; drives the need for substantial transmission and distribution system upgrades; and contributes to continued demand for natural gas and emerging hydrogen infrastructure. Similarly, the ongoing transition toward cleaner energy
5
sources is expected to support new solar, wind, and storage construction activity; require additional transmission and distribution capacity to integrate geographically dispersed renewable resources; and drive demand for pipeline infrastructure to support natural gas as a reliable resource, as well as for carbon capture and sequestration systems under development. In addition, federal infrastructure programs, including those established under the IIJA and IRA, provide funding for broadband deployment, clean energy innovation, grid modernization, water systems, and transportation‑related civil infrastructure, among others, each of which supports activity across multiple segments of our business.
We anticipate that these interconnected dynamics will create complementary opportunities across our segments as follows:
•Our Communications segment is expected to benefit from continued demand for fiber network expansion, wireless densification, and broadband deployment initiatives, including programs directed at unserved and underserved communities.
•Our Clean Energy and Infrastructure segment participates in the construction of renewable generation facilities, data center and industrial projects, and a wide range of civil infrastructure, all of which are expected to remain areas of significant investment.
•Our Power Delivery segment is positioned to support increasing requirements for transmission and distribution system expansion, reliability, resiliency, grid hardening and modernization resulting from rising electricity demand, growth in renewable generation, and aging grid infrastructure.
•Our Pipeline Infrastructure segment is expected to benefit from continued investment in natural gas distribution and transmission systems, water and wastewater networks, and emerging opportunities associated with carbon capture and sequestration, as well as hydrogen‑related infrastructure.
We expect that the convergence of these trends will form a broad, multi‑year investment cycle in U.S. communications, energy and infrastructure systems. Because our service offerings span multiple components of these systems, investment in one area frequently generates related demand in others. As a result, we believe that the diversification of our business in these complementary markets positions us to benefit from the expected long‑term investment associated with these developments.
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
Demand for seamless connectivity across wireless and wired devices continues to accelerate, driven by high-speed internet requirements, broadband expansion, AI data center growth, and data transmission, and such accelerated demand for connectivity continues to spur demand for fast and more reliable wireless and wireline/fiber communications network services. The proliferation of mobile devices, remote technologies, streaming, user generated content, e-commerce, AI applications, and the “Internet of Things (IoT)” is creating significant pressure for new and upgraded networks to meet increasing data traffic and reliability demands of these technologies.
According to IBISWorld’s October 2025 publication, “Wireless Tower Construction in the U.S.” (the “IBISWorld October 2025 publication”), revenue for the wireless tower construction industry is expected to grow to $15.7 billion over the five year period through 2030, reflecting continued investment in this industry. The IBISWorld October 2025 publication also predicts that the downstream telecom sector will invest substantially to maintain existing and establish new infrastructure to support the growing demand for high-speed internet connections.
We believe there will be significant fiber network expansion resulting from the combination of data center investments, carrier spend, and government programs that are expected to incentivize private investment in telecommunications infrastructure. Companies are making substantial investments in data centers to support AI initiatives, with robust fiber networks and connectivity serving as key growth drivers. This trend is creating opportunities to support and enhance data center connectivity, as new facilities are being developed farther from traditional locations. Additionally, according to Grand View Research, in its U.S. Fiber To The Home Market Size and Outlook (2025-2030) report, the United States fiber to the home market is expected to grow at a compound annual growth rate of 12.7% from 2025 to 2030.
Telecommunications providers have invested and continue to invest significant capital and other resources to deliver advanced telecommunications, and more recently, to enable enhanced AI applications, by deploying the latest infrastructure and are projected to play a significant role in shaping the future as both commercial and consumer markets continue to leverage 5G wireless technology. 5G mobile networks have been steadily growing and improvements to existing long term evolution and high-speed data networks are expected to continue over the coming years, providing a platform for the IoT, which can be harnessed to drive innovation and improvements in commerce, transportation, supply chain, research, healthcare, education, public safety, and the development of “Smart Cities,” “Smart Homes” and “Smart Farming,” among many other applications.
In response to these growing opportunities, service providers are expanding, densifying, including in building coverage, and optimizing 5G wireless and wireline/fiber network capacity. Compared to previous wireless generations, 5G requires more extensive network architecture changes, including additional and upgraded towers, higher bandwidth small/micro cells, distributed antenna systems, and expanded fiber networks, resulting in sustained construction, upgrade and maintenance activity. Additionally, there are several initiatives designed to drive development of telecommunications and 5G infrastructure in rural areas. We believe that continued nationwide 5G build-outs, deployment of small/micro cells, fiber expansion by major carriers, and ongoing demand for retrofits and upgrades of existing towers to support 5G (as noted in IBISWorld’s October 2025 publication), will drive multi-year demand for telecommunications infrastructure.
The IIJA provides approximately $65 billion of funding to improve and expand U.S. broadband infrastructure and affordability, including $42 billion allocated through the Broadband Equity, Access and Deployment (“BEAD”) Program to support planning, deployment, and adoption initiatives in unserved and underserved areas. In addition, the Rural Digital Opportunity Fund committed to provide up to $20 billion over ten years to support high-speed broadband deployment in rural communities. Carriers are also investing in telecommunications infrastructure to expand their fiber footprint across the nation. One such example is the AT&T and BlackRock Alternatives private equity fiber partnership, Gigapower LLC
6
(“Gigapower”), which will operate a commercial fiber-optic platform in the United States. While still in the early process of scaling, carriers continue to stress the importance of these builds and are experiencing momentum in fiber performance in Gigapower geographies. Based on this performance, AT&T and BlackRock plan to grow and are looking for opportunities to expand Gigapower’s network beyond the initial 1.5 million locations announced in 2022, including growth in both existing and new geographies.
The U.S. market for Smart City initiatives is expected to be driven by continued advancements in IoT, AI, and cloud technologies. Smart City initiatives encompass a wide range of technologies, including Wi-Fi kiosks, adaptive smart lighting systems, utility and water management solutions, smart waste management, real-time traffic and parking optimization, amongst other technologies. Similarly, the U.S. Smart Home market includes technologies that represent a wide range of solutions for monitoring, controlling and automating functions in a home, including home intelligence and connected home technologies. Smart City and Smart Home technologies are expected to benefit from the global expansion and densification of 5G, and highlight significant opportunities for infrastructure, development and service providers, particularly in installation and maintenance solutions, including for our install-to-the-home services offerings.
As one of the largest providers of communications infrastructure services, we believe that we are well-positioned to benefit from the expected opportunities in the telecommunications market as previously described.
Opportunities in our Clean Energy and Infrastructure Segment
Growing electricity demand and the need for additional generation capacity are driving changes in U.S. energy infrastructure and the energy mix, including increased reliance on renewable energy sources to add scalable capacity. According to a Deloitte analysis in its 2026 Power and Utilities Industry Outlook (the “2026 Deloitte Power and Utilities Outlook”), the U.S. is experiencing a surge in electricity demand, driven in part by a confluence of unprecedented electrification related to AI, alongside electrification in transportation and industry. The 2026 Deloitte Power and Utilities Outlook also indicates peak demand is projected to grow by approximately 26% by 2035 and data center demand alone could increase fivefold from 2024 to 2035. However, new supply is not becoming available at a pace adequate to meet demand. According to a Deloitte analysis in its 2026 Renewable Energy Industry Outlook report, renewable energy led U.S. 2025 capacity additions, accounting for 93% of new capacity through September 2025, with solar and storage comprising more than the majority.
Renewable energy is expected to play an increasingly significant role in U.S. electricity generation, with renewables projected to approach nearly half of total electricity generation by 2040, according to a March 2025 “U.S. National Power Demand Study” conducted by S&P Global Commodity Insights. Consistent with this long-term outlook, renewable energy has led U.S. generation capacity addition through September 2025, and several states are expected to introduce or expand renewable energy targets. Governmental and policy initiatives are expected to drive growth, including the IIJA, which allocates $65 billion to power infrastructure and energy programs. IIJA funding includes investments in fuels and technologies, clean energy supply chains, battery power initiatives, solar research and development, and clean hydrogen, among other initiatives. While the IRA initially provided approximately $370 billion in clean energy incentives through tax credits, grants, and loan guarantees, the One Big Beautiful Bill Act (“OBBBA”), signed into law on July 4, 2025, accelerated the phaseout of certain clean energy tax credits established under the IRA, including the clean electricity investment and clean energy productions credits for solar and wind projects, which may reduce longer term demand for such projects. Despite these policy changes, renewables have continued to account for the majority of recent U.S. capacity additions through September 2025, reflecting continued demand for additional generation capacity and supporting a favorable long-term outlook for renewable energy infrastructure development.
Growing corporate initiatives for smaller, standalone distributed generation facilities, together with regulatory and other policy initiatives at the state and municipal levels, have spurred demand for clean energy production from sustainable power sources, including wind, solar, biomass and other sources. Many states have adopted renewable portfolio standards or renewable energy goals to diversify their energy resources, promote domestic energy production and encourage economic development. Rising state renewable portfolio standards, increasing levels of corporate and residential demand, and improving economic competitiveness of renewable sources continue to be key drivers for their growth. We expect that ongoing efforts to enhance electric grid resiliency may continue to support incremental investment in renewable energy solutions, as utilities and certain customers consider the potential adoption of renewable microgrids, including energy storage systems, to help support critical facilities. Additionally, and subject to market conditions and regulatory developments, we believe that the wind sector could benefit over time from potential replacement and repowering activity involving existing wind turbines and foundations with next-generation, higher-efficiency equipment, as well as from maintenance requirements associated with aging wind farms.
As a result of the above trends and factors, we expect continued demand for construction of renewable and other clean energy infrastructure in the coming years. These expected sources of growth may be adversely affected, however, by technological changes that could mitigate or slow the increase in demand for clean energy, changes in governmental policies that reduce tax or funding incentives and changes in governmental processes that delay or reduce investments in projects, as well as changes in climate and environmental policies that contribute to demand for clean energy infrastructure. See Item 1A. “Risk Factors” under “Changes to laws, governmental regulations and policies, including those pertaining to governmental permitting, tax incentives, government funding programs and spending policies, as well as advances in artificial intelligence, could affect demand for our services, or cause delays or cancellations of projects. Additionally, demand for construction services depends on industry activity and expenditure levels, which can be affected by a variety of political, macro-economic and market factors. Our inability or failure to adjust to such changes or factors could adversely affect our results of operations, cash flows and liquidity.”
We also provide heavy civil infrastructure construction services, including the construction and maintenance of buildings, roads, bridges, rail, water/sewer systems and other civil infrastructure, including data center infrastructure. We believe that the incentives under the IIJA and other policies, as well as initiatives to upgrade and replace aging infrastructure, will lead to increased investment and future growth opportunities in this area. The IIJA includes approximately $110 billion of funding for roads and bridges, including $40 billion of funding for bridge repair, replacement and rehabilitation and $16 billion of funding for other major infrastructure projects, as well as approximately $50 billion of funding for water infrastructure, including climate resilience and drought and flood protection.
7
We believe that 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. We expect that the need for baseload backup power generation, coupled with the relative low price and environmental advantage of cleaner burning natural gas will continue to drive demand for gas-fired electrical generating plants. In addition, the transition to clean energy is driving recent trends to convert coal-fired power plants to lower carbon fuel sources such as solar, wind, geothermal, biofuel, biomass, hydrogen or a combination thereof. Coal-fired power plants are also being converted into battery storage facilities for renewable energy. A wide variety of industries may seek to expand, convert or construct new plants to take advantage of more economical, cleaner, lower cost and lower carbon fuel sources.
Converting existing power plants to renewable energy sources is an attractive option, given that existing power plants have electric infrastructure, including the power lines, transformers and other equipment that is required to connect the power to the grid. Industrial facilities and power plants in the biofuels/biomass, food processing, lithium recycling, natural gas and related industries present opportunities as additional domestic energy reserves are produced, transported and processed.
We are one of the leading renewable contractors in North America, with expertise in wind, solar and other renewables, as well as a leading contractor in the construction of industrial and other power plants and heavy civil infrastructure, and we expect to benefit from market trends in these industries.
Opportunities in our Power Delivery Segment
The U.S. electrical transmission and distribution infrastructure, referred to as “the grid,” is composed of a network of electric generating facilities, high voltage transmission lines, substations and distribution lines that bring power to homes and businesses. Demand for the grid is fueled by the consistent need for more efficient power services as the U.S. economy is dependent upon the reliable delivery of adequate levels of electricity. The grid will continue to require significant ongoing maintenance, upgrade and expansion to continue delivering reliable and affordable power. This will include strengthening aging infrastructure, addressing future grid resiliency and modernization efforts (“Smart Grid”) and adapting to changing energy supply, population movement and distribution requirements, including the acceleration of electrification in transportation and industry, data center infrastructure, and buildings and homes, all of which could and are expected to materially increase the demand for electricity. According to a May 2025 publication by the U.S. Energy Information Administration, after almost two decades of relatively flat electricity consumption change, electricity consumption hit an all-time high in 2024, and is forecasted to continue growing at an average rate of approximately 1.7% in 2026. As discussed within the Opportunities in our Clean Energy and Infrastructure Segment section above, the U.S. is experiencing a surge in electricity demand, driven in part by a confluence of unprecedented electrification related to AI, alongside electrification in transportation and industry. According to the 2026 Deloitte Power and Utilities Outlook, peak U.S. electricity demand is projected to grow by approximately 26% by 2035 and data center demand alone could increase fivefold from 2024 to 2035. We expect the projected energy load growth in the U.S. to drive meaningful investment in both power generation and grid expansion and modernization.
According to IBISWorld’s April 2025 publication, “Transmission Line Construction in the U.S.”, the growth in electricity demand will require an expansion of electricity generation and transmission capacity, and increased electrical infrastructure will elevate demand for transmission line construction services. We expect future growth in electric transmission and distribution infrastructure from projects to digitize, modernize, harden and secure the grid against increasing levels of disruption from natural and man-made disasters, including extreme and intensifying weather events, wildfires and potential cyber-attacks, as well as to address changing energy supply requirements and grid reliability. In addition, changes in U.S. energy infrastructure and energy mix, such as the transition to clean energy generating assets are expected to lead to increased demand and investment in electric infrastructure, with a changing fuel mix that is moving toward lower carbon and more sustainable energy sources, such as natural gas and renewables.
As discussed within the Opportunities in our Clean Energy and Infrastructure Segment section above, renewables accounted for 93% of 2025 U.S. electricity capacity additions through September 2025 and renewables are projected to reach nearly half of total generation by 2040. The projected growth in renewable energy generation is expected to require significant investment in new transmission lines and substations. Because the site locations of wind, solar and other renewable power generation resources are typically sensitive to weather and geographic conditions, often requiring locations in remote regions of the country far from industrial users and major population centers, they may require new transmission infrastructure to connect to the grid, as well as grid updates to provide for storage of electricity from renewable energy sources, and capabilities that can accommodate supply and demand for these new energy sources. These expected sources of growth may be adversely affected or delayed, however, by technological changes that could mitigate the increase in demand for electricity and changes in governmental policies that reduce tax or funding incentives, or impact project permitting, as well as changes in climate and environmental policies that contribute to demand for power generation infrastructure. See Item 1A. “Risk Factors” under “Changes to laws, governmental regulations and policies, including those pertaining to governmental permitting, tax incentives, government funding programs and spending policies, as well as advances in artificial intelligence, could affect demand for our services, or cause delays or cancellations of projects. Additionally, demand for construction services depends on industry activity and expenditure levels, which can be affected by a variety of political, macro-economic and market factors. Our inability or failure to adjust to such changes or factors could adversely affect our results of operations, cash flows and liquidity.”
These trends, along with climate change initiatives, as well as the IIJA and IRA programs, which are designed to incentivize investment in clean energy technologies for power generation, are expected to drive significant future investment in electric infrastructure. The IIJA includes approximately $65 billion for upgrades to power infrastructure and energy programs, research and development of transmission and electricity distribution technologies and smart grid technologies. The funding is focused on grid reliability and security, renewable energy innovation and deployment, and ensuring supply chains critical for energy innovation. In addition, among the key provisions of the IRA is funding to address climate change, beginning with a rapid transition in the nation’s energy system to cleaner sources of electric power generation. The IRA includes billions of dollars in tax incentives, grants and loan programs to support the development, and accelerate deployment of clean energy power projects, including for energy generation, energy manufacturing, clean fuels, clean vehicles and energy efficiency. However, the OBBBA accelerated the phaseout of certain clean energy tax credits established under the IRA, which may reduce longer term demand for such projects.

We believe significant capital investment in the transmission and distribution system, including from the advancement of modern, smart energy solutions, will be required to meet the above-mentioned infrastructure requirements, and that we are well-positioned through our diverse service offerings to benefit from these developing trends.
Opportunities in our Pipeline Infrastructure 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. Our pipeline offerings include construction and maintenance services for pipeline distribution, including for natural gas, water, wastewater and carbon capture sequestration pipelines and pipeline integrity services for the energy and utilities industries. Our pipeline integrity services include replacement and repair of pipeline infrastructure, facilitating their safe use throughout their lifecycle. Our revenue related to pipeline infrastructure projects has fluctuated in recent years, and we anticipate that it will continue to fluctuate as demand for pipeline construction services is sensitive to levels of activity in the oil and gas industry, as well as industrial and utility customer demand and regulatory constraints.
Notwithstanding efforts to reduce reliance on fossil fuel-related energy sources and transition to renewable sources, we expect that natural gas power generation will continue to play a dominant role in U.S. power generation, both for primary power generation, and for baseload backup power generation to support intermittent clean energy sources. Although the Department of Energy’s 2025 Annual Energy Outlook (reference case data) assumes natural gas demand may peak within the next five years, it is expected to remain robust and hold strategic importance in meeting rising U.S. energy demand. Specifically, it is projected to account for approximately 40% of U.S. electricity generation through 2030, remaining the second largest source of energy behind renewable technologies through 2050. Further, as industrial production expands, it is predicted that sectors depending on energy-intensive machinery will increasingly demand greater volumes of natural gas. Additionally, in response to rising data center demand and supportive liquified natural gas (“LNG”) policies, it is predicted that companies will boost their capital expenditures and expand their shale acreage, according to a Deloitte analysis in its 2026 Oil and Gas Industry Outlook. A January 2026 analysis from Morningstar DBRS states strong underlying demand for natural gas in the United States is driving record pipeline capacity additions of 18 billion cubic feet per day in 2026, the highest since 2008, driven by significant increases in associated gas production, strong underlying demand from LNG exports and data centers, and a supportive regulatory environment.
Demand for LNG exports has risen in recent years and North American export capacity is on track to more than double by 2029, according to an October 2025 publication by the U.S. Energy Information Administration. At the same time, the U.S. federal administration has eased environmental regulations, including accelerating permitting reviews of natural gas pipelines and lifting prior pauses on LNG export approvals. As a result, we expect sustained demand for new pipeline infrastructure to transport LNG to coastal export facilities over the coming years, including interstate and intrastate pipelines connecting producers to key export terminals. Further, according to IBISWorld’s April 2025 publication, “Oil & Gas Pipeline Construction in the U.S.”, many mainline gas pipelines in the United States were built more than 60 years ago, increasing the importance of maintaining the aging infrastructure. We believe that gas utility distribution spending for replacement and rehabilitation of aging infrastructure will accelerate over the next several years due to regulatory, sustainability and safety concerns. Similarly, we expect that aging pipeline infrastructure will increasingly require replacement lines and pipeline integrity services as our customers look to enhance the safety, productivity and lives of existing infrastructure.
The United States Environmental Protection Agency (“EPA”) has identified significant long-term funding needs for water and sewer infrastructure, which we expect will drive demand across our diverse water service offerings. According to the EPA’s 2022 Clean Watersheds Needs Survey, over $630 billion will be required over 20 years to address wastewater and stormwater infrastructure needs. Similarly, the EPA’s 2023 Drinking Water Infrastructure Needs Survey and Assessment estimates an additional $625 billion will be required for drinking water infrastructure over a 20 year period. These investments are driven by aging infrastructure, emerging contaminants, and the need for climate resilience.
Ongoing decarbonization efforts and carbon emission reduction initiatives are expected to drive demand for carbon capture and sequestration technologies, as well as the use of hydrogen as a clean energy power source. Pipeline infrastructure is expected to play a key role in the transformation to low carbon energy sources, which could involve constructing new pipelines or repurposing existing infrastructure, and supporting new carbon capture and hydrogen technologies, and we believe that we are well positioned to support these developing market trends in the energy transition. In light of these trends, we are continuously investing in capabilities to further support carbon capture and hydrogen technology infrastructure.
We believe that the above-mentioned trends will support continued levels of future project activity across our diversified pipeline capabilities and that we are well-positioned to benefit from these trends. While short-term demand may fluctuate with commodity cycles, we expect that long-term trends in energy transition, infrastructure modernization, and regulatory compliance present sustained demand for our services.

Our Clean Energy and Infrastructure segment revenue has grown significantly from $300 million in 2017 to approximately $4.7 billion in 2025. Our renewable and other clean energy technologies business, which represented approximately 3%, or $170 million of our consolidated revenue in 2017, has grown to approximately 19%, or $2.7 billion of our consolidated revenue in 2025. Assuming the trend towards diversification of power generation sources to sustainable and cost effective clean energy
10
sources continues, as well as a continued focus on the reduction of carbon emissions from cleaner, lower carbon energy sources, we believe that great opportunity lies ahead as we help our customers address these changing market demands.
Power delivery infrastructure. We believe the nation’s electrical transmission and distribution grid infrastructure will continue to require significant ongoing maintenance, upgrade and expansion to meet the expected increase in demand for electricity, resulting, in part, from the surge in electrification, including from AI-related data center demand and the acceleration of electrification across transportation, industrial processes and homes. As discussed above, demand for electricity is driving changes in energy infrastructure, including increased reliance on sustainable renewable power sources, which we believe will drive significant capital investment. Renewable energy accounted for 93% of 2025 U.S. electricity capacity additions through September 2025, and is projected to account for nearly half of total electricity generation by 2040. We build the infrastructure that connects our nation’s power generation sources to consumers, including infrastructure solutions that link remotely located renewable electric generation capacity to energy consumers and provide access to new renewable and efficient natural gas and other power generation sources, as well as grid updates to provide for the storage of electricity and to accommodate the supply and demand requirements of renewable energy sources. We also work with our customers to design and build innovative, smart energy solutions, including projects to digitize, modernize, secure and harden the grid, including from the potential effects of extreme and intensifying weather events, wildfire mitigation and restoration services and the upgrade of aging and overstressed electric infrastructure. Our projects improve the performance, safety, resiliency and efficiency of the nation’s electrical grid and advance the goal of modern, smart energy solutions for our nation’s future, as well as the development of new infrastructure to address the changing energy supply and diversification of power generation sources to sustainable and cleaner, lower-carbon energy sources.

We are participating in the buildout of our nation’s telecommunications infrastructure, helping to revolutionize telecommunications technologies across the U.S.
Pipeline infrastructure and carbon initiatives. Investments in pipeline integrity and line maintenance promote environmental and public safety, including methane reduction initiatives, while enhancing the safety, productivity and useful lives of our customers’ assets. Our natural gas construction services, which represented $1.6 billion, or 11% of our revenue in 2025, help our customers access and distribute cleaner burning, lower carbon emission natural gas throughout the United States. With continued growth in power generation from renewable energy sources, natural gas provides an important baseload backup power source to support intermittent renewable energy sources. Additionally, pipeline infrastructure provides a lower carbon emission and environmentally safer transportation alternative for energy products versus truck and rail transport.
Ongoing decarbonization efforts and carbon emission reduction initiatives are expected to drive demand for carbon capture sequestration technologies, as well as the use of hydrogen as a clean energy power source. Pipeline infrastructure is expected to play a key role in the transformation and diversification of power generation sources, which could involve construction of new or repurposing of existing pipeline infrastructure for new applications, and in the development of carbon capture sequestration and hydrogen technologies, and we believe that we are well positioned to support these developing market trends.

We build expansive water pipeline gathering networks and offer water pipeline services that increase the efficiency of water used in energy field operations in an environmentally-focused manner. In addition, our water pipeline services include projects that allow for the recycling of water, thereby reducing freshwater requirements as well as the amount of water disposed. Additionally, the use of water pipelines reduces the need for trucking, which saves time, money and reduces pollution and carbon emissions.
Emergency restoration services. The increased frequency and severity of weather and climate-related events, including hurricanes, wildfires and other storms, exacerbated by changing climate conditions, have accelerated the need for power and telecommunications reliability and restoration services. Our dedicated restoration crews help to restore power and telecommunications services, and provide both preventative and restoration efforts for wildfire-related events. Our crews are among those that are called upon to maintain and patrol electrical lines during high-risk periods, such as in periods of drought, high wind and extreme temperatures, so that power lines can be proactively and safely managed, as well as to assist with restoration efforts following wildfire events. We also provide wildfire mitigation services, including grid hardening and power line undergrounding, whereby power lines are buried in areas considered to be at high risk for fires. We also provide electrical grid hardening services in several regions of the country to reduce the risk of storm outages caused by damage to overhead power lines during a storm. These efforts include the movement of overhead power lines and related infrastructure underground, as well as replacement of wood poles with concrete or steel poles capable of withstanding significant storm events. MasTec is proud to work with and support communities affected by natural disasters, including repair and modernization efforts for telecommunications and electric grid infrastructure.
Environmental planning, compliance and remediation. Environmental planning and compliance are a top priority on all MasTec projects, and are a key element of construction projects across the nation. Our environmental services group specializes in all aspects of environmental planning, permitting and compliance within energy infrastructure. We have expertise in environmental inspection and compliance, environmental permitting, planning and pre-construction services, natural resources management, including wildlife and sensitive natural resource protection, siting and feasibility studies and community and government outreach designed to build lasting community relationships. We also have expertise in environmental remediation services, including site development, environmental site closure and coal combustion residuals management services.

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 construction, installation, maintenance and upgrade services to project management and engineering 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, 2025, 2024 and 2023, revenue derived from projects performed under master service and other service agreements totaled 44%, 41% and 40%, respectively, of consolidated revenue.
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, broad service capabilities, operational scalability, geographic reach, financial stability and reputation for reliability, efficiency and customer service, as well as the relationships developed between our customers and our senior management and project management teams are important to our being selected and retained by our customers. See Note 14 - Segments and Related Information and Note 15 - 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 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. Based on current expectations of our customers’ requirements, we anticipate that we will realize approximately 74% of our estimated year-end 2025 backlog in 2026.

As of December 31, 2025, 47% of our backlog is estimated to be 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, regulatory or other delays or cancellations, including from factors discussed in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - General Economic, Market and Regulatory Conditions.” These effects, among others, 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 due to these effects and/or other factors. There can be no assurance as to our customers’ requirements or that actual results will be consistent with the estimates included in our forecasts. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings.
Backlog 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
14
incorporated by reference. As of December 31, 2025, total 18-month backlog differed from the amount of our remaining performance obligations due primarily to the inclusion of $8.3 billion of estimated future revenue under master service and other service agreements within our backlog estimates, as described above, and the exclusion of approximately $4.0 billion of remaining performance obligations and estimated future revenue under master service and other service agreements in excess of 18 months, which amount is not included in the backlog estimates above. Backlog expected to be realized in 2026 differs from the amount of remaining performance obligations expected to be recognized for the same period due primarily to the inclusion of approximately $4.8 billion of estimated future revenue under master service and other service agreements included within our backlog estimate, which is not included within our remaining performance obligations for the same period.
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 our services, 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 a business development and 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 that our longstanding relationships with our customers, industry expertise and our reputation for reliability, efficiency and customer service facilitate our potential and recurring business relationships. 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 other arrangements. Our executive management team supplements these efforts at the national level.
Safety and Insurance/Risk Management
We have a proactive safety culture and we strive to instill and enforce safe work habits in our employees. Our employees are required to participate in training programs relevant to their employment, including all those required by law. We actively train our workforce in everyday safety practices and provide detailed guidelines that are required to be followed as work tasks are contemplated and completed. Training programs are tailored to an employee’s job function, responsibilities and level of experience and are designed in accordance with industry best practices and standards. We evaluate employees in part based upon their safety records and the safety records of the employees they supervise. Team members are responsible for preventing incidents, injuries and occupational illnesses, and our project leadership team is tasked with ensuring that projects are accomplished in a safe, productive, environmentally and quality-focused manner. Our business units have established robust safety programs to monitor and improve compliance with safety procedures and regulations, and through our risk management programs, we educate our staff, subcontractors and suppliers on safety matters. We strive continuously to assess and improve our safety programs and performance. We also provide training for other workplace and risk management programs, including for cybersecurity, discrimination and harassment, human trafficking awareness, emergency preparedness and other workplace hazards, among others.
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. In addition, we 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 also manage certain of our insurance liabilities indirectly through our wholly-owned captive insurance company, which reimburses claims up to the applicable insurance limits. 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 15 - Commitments and Contingencies in the notes to the audited consolidated financial statements, which is incorporated by reference.
Adverse climate and weather events, including drought conditions and high winds, have increased operational and legal risks in certain locations for us and other contractors. In particular, wildfire risks associated with electrical power and other infrastructure have increased the potential for liabilities and related costs (particularly as these events can be started by electrical power and other infrastructure on which we have performed services), which could adversely affect our financial results and position. We procure insurance from the commercial insurance market to cover a portion of such risks; however, limited capacity and high costs in insurance markets have increased our reliance on self-insurance for these exposures with respect to certain geographic areas.
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 for project-related materials or supplies required for the projects we manage. We also depend on the availability of certain equipment to perform our services. We operate a diverse fleet of on-road and off-road equipment. Substantially all of our equipment is obtained from third-party vendors, and we are not dependent upon any single vendor for our equipment requirements. We also 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 single independent contractor. A number of factors that we may not be able to accurately predict or control could result in increased costs for, or delays in delivery of, materials and equipment, including supply chain disruptions.
15
In recent years, our industry was impacted by market-related supply chain disruptions, most notably constraints and delays affecting certain materials for our clean energy customers. While these supply chain disruptions have eased, our operations could be negatively affected in the future if such disruptions were to recur, or if geopolitical tensions exacerbate global supply constraints. For example, during the year ended December 31, 2025, the U.S. government announced or imposed a variety of tariff or other trade actions, in response to which many countries have announced retaliatory trade actions, including tariffs on U.S. exports or bans by foreign countries on certain of their exports. These actions have increased the cost of importing certain construction materials into the U.S., including steel, concrete, copper and solar panels, and have caused disruption and uncertainty to both international trade and supply chains. More recently, on February 20, 2026, the U.S. Supreme Court ruled that certain trade tariffs imposed by the U.S. federal government under the International Emergency Economic Powers Act (“IEEPA”) were unconstitutional. Following the U.S. Supreme Court’s decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. Significant uncertainty remains regarding the status of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended. While the duration, extent and effects of these tariffs and trade actions cannot be predicted with certainty, these policy changes could impact our ability to execute projects and have a material adverse effect on our business, financial condition, and results of operations.
We need working capital to support seasonal variations in our business, including the effects of weather and other conditions on outdoor construction and maintenance work, the spending patterns of our customers and the effects of regulatory and market factors, all 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, primarily large national firms, as well as small local independent companies. Certain barriers to entry exist in the markets in which we operate, including adequate financial resources, technical expertise, high safety ratings, established customer relationships 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 that 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 and Environmental 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 service commission or communications companies regulated by the Federal Communications Commission (“FCC”), we are generally not subject to such regulation and oversight. Our operations are, however, subject to numerous laws and regulations, among them:
• environmental laws and regulations;
•regulations related to worker safety and health, including those established by the Occupational Safety and Health Administration (“OSHA”), Mine Safety and Health Administration (MSHA), and other local and state equivalents;
•regulation relating to employment, including wage and hour regulations (e.g., Fair Labor Standards Act), I-9 regulations and regulations associated with our collective bargaining agreements and unionized workforce;
•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;
• building and electrical codes;
•cyber and other data protection and security requirements; and
•applicable U.S. and non-U.S. anti-corruption regulations.
We are subject to numerous environmental laws, regulations and programs, including with respect to 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 and critical habitats. Our operations require careful adherence to environmental regulations because they could have impacts on groundwater, surface waters and other environmentally sensitive areas. Similarly, certain of our construction operations often require us to operate in remote areas involving environmentally sensitive habitats as well as areas that are subject to risk of wildfire.
We have a substantial investment in construction equipment that utilizes fuel. Any changes in laws requiring us to use equipment that runs on alternative power sources 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. In addition, we
16
could be subject to liability for legacy environmental matters arising from our recently acquired businesses. From time to time, we may incur unanticipated and substantial 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.
Additionally, there are environmental regulations under consideration to address climate change, regulate and report on emissions of GHG and encourage the use of clean energy technologies. We regularly monitor proposed regulations and legislation and have processes in place to adapt our business and operations, as necessary, to meet any such new requirements.
Financial Information About Geographic Areas

We encourage all our employees to take an active role in living a healthy lifestyle and offer wellness tools and resources to help achieve and maintain good health. We offer a comprehensive and flexible benefits program, including medical, dental, vision and prescription insurance, as well as access to telehealth services to assist employees with medical and mental health matters. In addition, to help our employees build a financially secure future, we offer a 401(k) plan with matching benefits, an employee stock purchase plan, life and disability insurance plans and a flexible spending account to help employees cover medical expenses. We also offer employees support for personal and work-life issues, including health, legal and financial matters.
Professional and Career Development. We believe that professional development is essential to the success of our business, as it drives employee engagement and ensures that our team members have the requisite skills and training to deliver the highest level of excellence to our customers. Our employees’ career development begins with the onboarding process and continues throughout their careers. Ongoing training is designed to develop our employees’ technical, professional and leadership skills and is customized to meet the qualifications and requirements necessary for them to succeed in their positions. We invest significant resources in education, certification, training programs and other professional development opportunities, including apprenticeship- and leadership-oriented training programs, tuition reimbursement for qualified training programs, sponsored attendance at industry conferences, departmental and divisional leadership conferences, employee training centers and advancement opportunities within and across businesses and divisions. We seek to develop and cultivate current and future leaders, and design our training programs to create high performing teams, improve productivity, positively affect employee motivation and retention and further enhance career development opportunities. We believe that our team culture, along with competitive salary and benefits packages and our focus on employee training and career development, including opportunities for promotion and mobility within our organization, helps us to attract and retain a diverse, qualified and experienced workforce.
Team Culture. Our success depends upon the success of our team, which requires us to have exceptional team members, as well as an exceptional team. Teamwork is part of our culture and is one of our core values. We believe that our employees and our customers benefit from the collective and well-coordinated efforts that result from effective employee engagement, teamwork and collaboration. We seek to foster an

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 above.
Risks Related to the Industries We Serve
Changes to laws, governmental regulations and policies, including those pertaining to governmental permitting, tax incentives, government funding programs and spending policies, as well as advances in artificial intelligence, could affect demand for our services, or cause delays or cancellations of projects. Additionally, demand for construction services depends on industry activity and expenditure levels, which can be affected by a variety of political, macro-economic and market factors. Our inability or failure to adjust to such changes or factors could adversely affect our results of operations, cash flows and liquidity.
The industries we serve are subject to effects of new or changing governmental regulation, including for climate-related matters, governmental permitting, environmental approval processes, stricter enforcement of existing laws and regulations, climate change litigation, and political or social activism, any of which could result in reduced demand for our services, delays in the timing of projects, or cancellations of current or planned future projects. Many of our customers face stringent regulatory and environmental requirements and permitting processes, including governmental regulations and policies. Most of our communications customers are regulated by the FCC, and our energy customers are regulated by the Federal Energy Regulatory Commission, among others. In addition, our utility customers are regulated by state public utility commissions. These agencies or governments could change their interpretation of current regulations and/or may impose additional regulations, or change government funding programs or spending policies, including the potential for reduced support for renewable energy projects. Our customers could be adversely affected by regulatory initiatives or additional requirements, restrictions or legislation imposed by federal, state, local, or foreign governments, including from climate-related matters and/or any related changes in end-customer demand. The current U.S. administration has implemented various policies and actions that could inhibit wind or renewable energy development activity and, although to date these have been overturned by the courts, or are the subject of ongoing litigation, these policies and actions could create uncertainty that could cause customers to reduce the scope of, delay or cancel renewable energy projects. Additionally, the current U.S. administration has established initiatives to reform federal government processes and reduce expenditures. Implementation of these initiatives, along with pressures on and uncertainty surrounding the federal budget and budgetary priorities, could adversely affect funding and, as a result, demand for our services. These factors, as well as potential disruptions related to artificial intelligence in the industries we serve, could have an adverse effect on our customers and reduce demand for our services and adversely affect our results of operations, cash flows and liquidity.
18
We build renewable energy and other infrastructure for which the development may be partially dependent upon federal tax credits, including from the IIJA and IRA, and for renewable infrastructure, existing renewable portfolio standards and other federal or state tax incentives. The IIJA and IRA provide funding in many of the markets in which we operate. Delays and uncertainty related to the implementation and pace of spending, or to project permitting or other matters under the IIJA, IRA and/or other programs, has caused, and could continue to cause, uncertainty related to the timing of our current and future project work expectations. Additionally, elimination of, reduction of, or changes to the IIJA, IRA, existing renewable portfolio standards, environmental policies, tax incentives and/or similar programs could negatively affect demand for our services. In July 2025, OBBBA was signed into law, and while it extended many provisions of the Tax Cuts and Jobs Act of 2017 (“TCJA”), it also accelerated the phaseout of certain clean energy tax credits established under the IRA, including the clean electricity investment and clean energy production credits for solar and wind projects, which may reduce longer term demand for such projects. We cannot predict, however, whether, when, or to what extent these changes in governmental programs and spending policies will impact the industries in which we operate in the long term.
All of the above factors could result in fewer projects than anticipated or a delay in the timing of these projects, which could negatively affect demand for our services and have a material adverse effect on our results of operations, cash flows and liquidity.
Tariff and trade actions by the United States and other countries could have a material adverse effect on our business, financial condition, and results of operations.
During the year ended December 31, 2025, the U.S. government announced significant trade policy and tariff actions on imports from a broad set of countries, including Canada, Mexico, European Union member states, Japan, Germany and China, in response to which many countries announced retaliatory trade actions, including tariffs on U.S. exports or bans by foreign countries on certain of their exports. These actions have increased the cost of importing certain construction materials into the U.S., including steel, concrete and solar panels, and have caused disruption and uncertainty to both international trade and supply chains. More recently, on February 20, 2026, the U.S. Supreme Court ruled that certain trade tariffs imposed by the U.S. federal government under the IEEPA were unconstitutional. Following the U.S. Supreme Court’s decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. Significant uncertainty remains regarding the status of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended.
The duration, extent and effects of these tariffs and trade actions cannot be predicted with certainty but these and other trade policies could increase costs of key construction equipment and components thereof, as well as materials required for our customers’ projects (including steel, concrete, copper and solar panels), which could cause our customers to reconsider or reduce their capital expenditures, or could affect our customers’ capital spending plans and demand for our services. Accordingly, these trade actions and the widespread uncertainty and international tensions resulting therefrom, including, without limitation, effects on interest rates and on the value of the U.S. dollar relative to other currencies, could materially and adversely affect our business, financial condition and results of operations.
Unfavorable market conditions, including elevated levels of inflation and/or interest rates, supply chain disruptions, political regulatory or market uncertainty, including economic downturns and heightened geopolitical tensions and conflicts, could reduce capital expenditures in the industries we serve or could adversely affect our customers and result in decreased demand for our services.
Demand for our services has been, and will likely continue to be, cyclical in nature and vulnerable to unfavorable market conditions and/or downturns in the economy. Unfavorable market conditions, including elevated levels of inflation and/or interest rates, supply chain disruptions, political, regulatory or market uncertainty or public health matters could have a negative effect on demand for, or the profitability of, our customers’ services, which could have a material adverse effect on our business, financial condition and results of operations. We have been subject to, and may continue to be subject to, the general effect of elevated market interest rates and inflationary market pressures on our business, particularly with respect to labor, materials and fuel costs. Although the Federal Reserve lowered short-term interest rates in 2025, interest rates, particularly long-term rates, remain elevated. Additionally, inflationary conditions and general labor shortages over the past several years have resulted in wage inflation as well as increased competition for skilled labor. Inflation rates in the United States have increased significantly over the past several years and, while recent inflationary pressure has somewhat abated, we expect our labor, materials and fuel costs, in particular, to remain elevated if we continue to expand our operations and volume of work. We have not been, and may not be able to, fully adjust our contract pricing to compensate for these cost increases, which has affected, and may continue to affect, our profitability and cash flows. Inflationary pressures and the related elevated levels of market interest rates have caused, and could continue to cause, uncertainty for our customers, which has negatively affected, and could continue to negatively affect, their capital expenditure and maintenance budgets.
Should inflation persist or increase, interest rates could remain at elevated levels or increase, which, together with inflation, could have a significant negative effect on the economy in general, and on the construction industry in particular, as well as create volatility in the capital markets, which could adversely affect demand for our services, as well as our profitability, liquidity, cash flows and/or financial condition. We continually monitor general economic conditions and the market conditions of the industries our customers serve and their relative health compared to the economy as a whole. Uncertain or adverse economic or political conditions, the lack of availability of debt or equity financing and/or higher interest rates could cause our customers to reduce their capital spending or seek more favorable pricing and other contract terms and/or cause project cancellations or deferrals.
Our operations and/or our customers could be negatively affected by market-related supply chain disruptions caused by delays, shortages of, and increased costs for, the materials necessary to perform projects. While constraints and delays for certain materials, most notably, for certain of our clean energy customers, have eased, if such delays were to recur, it could affect our ability to perform these projects.
The oil and gas markets have historically been and are likely to continue to be volatile. Demand for pipeline construction services is sensitive to levels of activity in the oil and gas industry, as well as industrial and utility customer demand and regulatory constraints. Oil and gas prices are subject to large fluctuations in response to changes in supply and demand, including from: production and export/import volatility, climate change policies, and demand for alternative energy sources; disruptions in global economic activity, including from global sanctions and blockades;
19
legislative and regulatory changes; and a variety of other factors that are beyond our control. Such market volatility can affect our customers’ investment decisions and subject us to project cancellations, deferrals or unexpected changes in the timing of project work.
In addition, our operations and/or our customers, particularly in the Pipeline Infrastructure segment, could be negatively affected by market and political uncertainty, including from unrest and/or military actions involving oil-producing nations; and a variety of other factors that are beyond our control. Such market volatility can affect our customer’s investment decisions and subject us to project cancellations, deferrals or unexpected changes in the timing of project work. In particular, a reduction in the price of oil resulting from expanded oil supplies could reduce oil exploration activities that could adversely affect our Pipeline Infrastructure segment.
We may face risks related to health epidemics and pandemics or other outbreaks of communicable diseases. For example, the COVID-19 pandemic created significant volatility, uncertainty and economic disruption, including significant volatility in the U.S. economy and financial markets for several years, and negatively affected our operations during that period. A public health epidemic or pandemic poses the risk that we or our employees, customers and/or business partners may be prevented from conducting ordinary course business activities for an indefinite period of time, or that the health crises and their related impacts may otherwise interrupt or affect business activities, or cause us to incur incremental operational costs or experience lower levels of overhead absorption from a reduction in revenue, which could negatively affect our margins and profitability.
The industries we serve are highly competitive and subject to rapid technological and regulatory changes, as well as customer consolidation, any of which could result in decreased demand for our services and adversely affect our results of operations, cash flows and liquidity.
Our industry is highly fragmented, and we compete with a number of companies in the markets in which we operate, including large national firms that service regional and national markets, as well as small independent companies that service local markets. We also face competition from existing and prospective customers that employ in-house personnel to perform some of the services we provide. 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.
We derive a substantial portion of our revenue from customers in industries that are subject to rapid changes in technology, governmental regulation, changing consumer demands and consolidation. Technological advances in the markets we serve, including from climate-related initiatives, could render existing projects or technologies uncompetitive or obsolete, cause longer-term changes in consumer behavior, and/or alter our customers’ existing operating models. Our failure to rapidly adopt emerging technologies or adapt to changing customer requirements could adversely affect demand for our services and/or our profitability. If we lack the operational expertise or scale to adapt to emerging technologies, or if we face shortages of labor skilled in such technologies, we could experience project inefficiencies, an increase in wage costs or a decrease in revenue. Additionally, consolidation among our customers could result in the loss of customer revenue or could negatively affect customer demand, which could have a material adverse effect on our results of operations, cash flows and liquidity.
An impairment of the financial condition of one or more of our customers due to adverse market or other conditions could hinder their ability to pay us on a timely basis.
An impairment of the financial condition of one or more of our customers due to adverse market, industry or other conditions, as described above, could hinder our customers’ ability to pay us on a timely basis. In the past, we have incurred significant losses from customers who filed for bankruptcy or experienced financial difficulties, including from market or industry conditions, or following a general economic downturn, for which certain industry factors worsened the effect of the overall economic downturn on those customers. In difficult economic times, some of our customers 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 customer payments may require us to make a working capital investment, which could negatively affect our cash flows and liquidity. Our results of operations, cash flows and liquidity could be materially and adversely affected if a customer fails to pay us on a timely basis or defaults in making payments on a project for which we have devoted significant resources.
Risks Related to Our Business and Operations
Our failure to properly manage projects, or project delays, including those resulting from difficult work sites and environments, permitting issues and the availability of materials or equipment 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 operations involve and are increasing their mix of large-scale, complex projects, which can occur over extended time periods. The quality of our performance on such projects depends in large part upon our ability to manage our client relationship and the project itself, such as 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 on a larger scale if we miscalculate the resources or time needed to complete large-scale projects, in particular for projects with capped or fixed fees, or the resources or time needed to meet contractual milestones.
We perform work under a variety of conditions, including, but not limited to, challenging and hard to reach terrain and other 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.
20
We may encounter difficulties in engineering, delays in designs, or issues with the availability or receipt of materials or equipment provided by the customer or a third-party, certain of which have long lead-times. We may also encounter delays related to permitting and environmental approval processes; schedule changes; delays from failure of our customers to obtain rights-of-way in a timely manner; weather-related delays; delays by subcontractors in completing their portion of projects; and delays due to governmental, regulatory, market, political or other factors, some of which are beyond our control and could affect our ability to complete a project as originally scheduled. We could also encounter project delays due to political and social activism or local opposition, which could include injunctive actions or public protests related to the siting of our projects, and such delays could adversely affect our project margins. In some cases, delays and additional costs may be substantial, including from the substantial cost of certain of the materials and equipment necessary to complete projects, and/or if we are required to cancel or defer a project and/or compensate the customer for the delay or cancellation. 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, cancellations and/or project disputes could also negatively affect our reputation or relationships with our customers, which could adversely affect our ability to secure new contracts.
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 costs, 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, which could substantially exceed the amount we can charge for our associated services.
Our business is seasonal and affected by the spending patterns of our customers, project schedules, weather conditions, climate-related events, regulatory matters, including timing of governmental permitting, and market conditions, all of which expose us to variations in quarterly results.
Our revenue and results of operations can be subject to seasonal and other variations. Typically, our revenue is lowest at the beginning of the calendar year and during the winter months because harsher weather such as cold, snowy or wet conditions can affect our ability to perform outdoor services in certain regions and delay projects. Natural catastrophes or other extreme weather events, such as hurricanes, wildfires, flooding or other severe weather, could also affect our ability to perform outdoor services or utilize equipment and crews in affected regions, causing project delays or cancellations. Timing of governmental permitting could also result in greater seasonal and cyclical volatility than would otherwise exist under normal conditions. These events, as well as fluctuations in end-user and/or customer demand, regulatory, global, market, economic and/or geopolitical conditions, among others, could create increased volatility in our results and/or adversely affect demand for our services and our results of operations, cash flows and liquidity.
Our failure to recover adequately on claims against project owners, subcontractors or suppliers for payment or performance, or increases in warranty claims, 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 work not included in the original contract price. Similarly, from time to time, we present change orders and claims to our subcontractors and suppliers. We could incur reduced profits, cost overruns or project losses if we fail to properly document the nature of change orders or claims or are otherwise unsuccessful in negotiating an expected settlement. These types of claims can occur due to project owner-caused delays, changes from the initial project scope that result in additional costs, both direct and indirect, or from project or contract terminations, among other factors. 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 pending the resolution of the relevant claims. A failure to recover, or to recover in a timely manner, on these types of claims could have a material adverse effect on our liquidity and financial results.
Additionally, we generally provide warranty for the work we perform following substantial completion of a project. Warranty claims have historically not been material, but such claims could potentially increase. The costs associated with such warranties, including any warranty-related legal proceedings, could have a material adverse effect on our results of operations, cash flows and liquidity.
We may not accurately estimate the costs associated with services provided under fixed price contracts, which could adversely affect our profitability, results of operations and cash flows.
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. Our profitability would be reduced if actual costs to complete a project exceed our original estimates. 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 or our ability to execute according to our plans, 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.
In addition, we recognize revenue primarily over time under 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 contract 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, including the full amount of any expected project losses. 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
21
actual results from related estimates on a large project, or on several smaller projects, could be material. Any such adjustments could result in reduced profitability and negatively affect our results of operations.
Amounts included in our backlog may not result in actual revenue or translate into profits. Our backlog is subject to cancellation and unexpected adjustments and, therefore, is not necessarily an accurate representation of future operating results.
Our backlog consists of the estimated 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, amounts under master service and other service agreements, 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, which do not 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. 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, which estimates may prove inaccurate. Timing of revenue for construction and installation projects included in our backlog can be subject to change as a result of customer, regulatory or other delays or cancellations, including from permitting and other factors discussed in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under “General Economic, Market and Regulatory Conditions.” These effects, among others, could cause estimated revenue to be realized in periods later than originally expected, or not at all. From time to time, we experience postponements, cancellations and reductions in expected future work due to changes in our customers’ spending plans, market volatility, changes in governmental permitting, regulatory delays and/or other factors.
There can be no assurance as to our customers’ requirements or that actual results will be consistent with the estimates included in our forecasts. 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, or if amounts in our backlog are unprofitable, our results of operations, cash flows, liquidity and financial condition could be materially and adversely affected.
We maintain a workforce based upon current and anticipated workloads, and could incur significant costs and reduced profitability from underutilization of our workforce if the level of services we provide is significantly reduced, or if contract awards are delayed or not received.
Our estimates of future performance and results of operations depend, among other factors, on whether and when we receive new contract awards, which can affect the extent to which we are able to utilize our workforce. The rate at which we are able to 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, 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 can frequently change based on newly available information. In the case of large-scale or complex projects where timing is often uncertain, it is particularly difficult to predict whether and when we will receive a contract award, or when the project will begin. The uncertainty of contract award timing can present difficulties in matching the size of our workforce to our project needs, including due to uncertainty related to the implementation and pace of spending under governmental or other programs, and/or delays or uncertainty related to project permitting or other matters. 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, all of which could reduce our profitability and cash flows.
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. In addition, many of our contracts, including our service agreements, 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.
We derive a significant portion of our revenue from a few customers. Additionally, a significant portion 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. 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. See Note 1 - Business, Basis of Presentation and Significant Accounting Policies, Note 14 - Segments and Related Information and Note 15 - Commitments and Contingencies in the notes to the audited consolidated financial statements, which are incorporated by reference, for revenue concentration information.
We also derive a significant portion of our revenue from multi-year master service and other service agreements. Under these agreements, our customers have no obligation to undertake any infrastructure projects or other work with us. In addition, most of our contracts are cancelable on short or no advance notice, ranging from immediate cancellation to cancellation upon 180 days’ notice, even if we are not in default under the contract. 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.
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. We could experience a reduction in revenue, profitability and liquidity if we fail to win a significant number of existing contracts upon re-bid. Additionally, from time to time, we may 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.
22
If we are unable to attract and retain skilled and qualified employees and key personnel, 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 efficiently operate our business and maintain productivity and profitability. We may be unable to hire and retain a sufficiently skilled labor force to support our operating requirements and growth strategy. Our labor and training expenses could increase as a result of a shortage in the supply of skilled personnel, which could adversely affect our profitability. In times of low unemployment, such as the recent market environment, it can be difficult for us to find appropriately skilled and qualified personnel at affordable rates. Additionally, changes to U.S. immigration laws, regulations, or policies, could affect the availability of labor and the compensation of such labor.
We are also dependent upon retaining and recruiting qualified management to execute our business strategy. Our business is managed by a number of key executive and operational officers, many of whom have extensive industry experience. Additionally, as our business continues to expand and increase in complexity, we cannot be certain that our management structure will remain adequate and that we will be able to successfully attract, onboard, and retain qualified personnel. Lack of skilled labor, the loss of key personnel, labor shortages and/or increased turnover rates could negatively affect our ability to operate efficiently, and could lead to increased wage rates and overall employee costs to attract and retain appropriately skilled and qualified personnel, all of which could materially and adversely affect our results of operations, cash flows and liquidity.
Our financial results are based, in part, upon estimates and assumptions that may differ from actual results.
In preparing our consolidated financial statements in conformity with generally accepted accounting principles in the United States (“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. 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.
As acquisitions have been a component of our growth strategy, our balance sheet includes a significant amount of goodwill, other intangible assets, and long-lived assets, the value of which is dependent upon certain estimates and assumptions. Under U.S. GAAP, we are required to test goodwill for possible impairment annually, and whenever events occur that indicate impairment may exist. Impairment testing of goodwill involves qualitative assessments and quantitative tests to determine the fair value of our reporting units and is dependent upon estimates and assumptions. If we determine the fair value of a reporting unit with goodwill is less than its carrying value as a result of an annual or interim test, an impairment loss is recognized. We have recorded impairment losses in the past, and any future impairments to goodwill, other intangible assets, or long-lived assets could materially and adversely affect our results of operations and financial condition. See Item 7. Management's Discussion and Analysis of Financial Condition - Critical Accounting Estimates and Note 1 - Business, Basis of Presentation and Significant Accounting Policies in the notes to the audited consolidated financial statements, which are incorporated by reference, for further information about our critical accounting estimates and significant accounting policies.
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 accounting rules and regulations pursuant to FASB or SEC guidance could materially affect our reported financial results in a given period, and the adoption of new or revised accounting principles could require that we make significant changes to our systems, processes and controls, which could have an adverse effect on our results of operations, cash flows and liquidity.
Our business is subject to operational risk, including from occupational health and/or safety incidents due to operational, physical and/or environmental hazards, which could result in substantial liabilities and weaken our financial condition.
Our business is subject to operational, physical and environmental hazards due to the nature of services we provide and the conditions in which we operate. These hazards could result in health and/or safety incidents from electricity, fires, explosions, mechanical failures and weather-related events, among others. In addition, certain of our customers operate in locations and environments that could increase the likelihood and/or severity of potential operational hazards from climate-related factors, including wildfires. While we invest substantial resources in occupational health and safety programs, there can be no assurance that we will be able to mitigate all such hazards or avoid significant liability. The construction projects that we undertake 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. We also perform services in locations that are densely populated and have higher property and asset values, including in certain metropolitan and other geographic areas, which could potentially increase the effect of such hazards.
These risks and hazards, among others, can cause personal injuries and loss of life, severe damage to or destruction of property and equipment, harm to the environment and/or other consequential damages, and could lead to suspension of operations, large damage claims that could substantially exceed the amount we charge for the associated services, government enforcement actions or regulatory penalties, civil litigation or criminal prosecution. Claims and liabilities related to accidents and operational or other hazards can also arise through indemnification obligations to customers, our negligence, or otherwise, and such exposure could extend for years after we complete our services. Personal injury and other claims for damages, including for bodily injury or loss of life, could result in substantial costs and liabilities. Insurance coverage may not be available to us or may be insufficient to cover any of these liabilities and legal costs. Our insurance costs, including those related to our self-insurance programs, could increase if we incur liabilities associated with accidents and/or operational or other hazards. If we are not fully insured or indemnified against such liabilities and legal costs, or if a counterparty fails to meet its indemnification obligations to us in connection with such matters, it could materially and adversely affect our financial condition, results of operations or cash flows.
In addition, if serious accidents or fatalities were to occur, or if our safety records were to deteriorate, we could be restricted from bidding on certain work or from 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,
23
employee turnover or an increase in the costs of our projects, or could harm our ability to perform under our contracts, and/or our reputation and ability to enter into new customer contracts, all of which could materially and adversely affect our revenue, profitability and liquidity.
We are self-insured against several potential liabilities.
We maintain insurance policies with respect to automobile liability, general liability, employer’s liability, workers’ compensation and other types of coverages. We also manage certain of our insurance liabilities indirectly through our wholly-owned captive insurance company, which reimburses claims up to the applicable insurance limits. Our insurance policies are subject to high deductibles or self-insured retention amounts. We are effectively self-insured for substantially all claims because most claims against us do not exceed the deductibles under our insurance policies, and there can be no assurance that our insurance coverages will be sufficient or effective under all circumstances, or against all claims or liabilities to which we may be subject. In addition, insurance liabilities are difficult to assess and estimate due to many factors, the effects of which are often unknown or difficult to estimate, including the severity of an injury or an incident, the determination of our liability in proportion to other parties’ liability, the number of incidents not reported and the effectiveness of our safety programs. Any of these factors could expose us to significant liabilities and materially and adversely affect our business, financial condition, results of operations and cash flows.
We renew our insurance policies on an annual basis; therefore, the deductibles and levels of insurance coverage applicable to our policies may change in future periods. In addition, in the future, insurers could cancel or exclude certain items from our coverage, or we may elect not to obtain certain types of insurance coverage based on our assessment of the potential benefits of such coverage relative to its cost. Additionally, we cannot guarantee that future insurance coverage will be available to us at reasonable and competitive rates, or at all. For example, in recent years, due to the increased occurrence and potential future risk of wildfires in certain areas, insurers have reduced coverage availability and have increased the cost of insurance coverage for such events, which has resulted in a reduction of our level of coverage for wildfire events and has increased our reliance upon self-insurance. Any of these factors could increase our risk exposure and/or our cost of insurance coverage in the future, which could negatively affect our business, financial condition, results of operations and cash flows.
If our insurance costs exceed our estimates of insurance liabilities or if our insurance claims or our cost of coverage 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, liquidity and cash flows.
In the ordinary course of our business, we are 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, liquidated damages, consequential damages, punitive damages and civil penalties or other losses, or injunctive or declaratory relief. We could also be subject to litigation in the normal course of business from alleged violations of the Fair Labor Standards Act and state wage and hour laws. We may also become involved in customer disputes related to change orders and/or our entitlement to revenue in accordance with the terms of the applicable customer agreements. 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.
Claimants may seek large damage awards, and defending claims can involve significant costs. When appropriate, we establish accruals for litigation and other contingencies that we believe to be adequate based on factors such as current information, legal advice and our indemnity insurance coverages, and, when appropriate, we may recognize revenue in light of these factors. We reassess our potential liability for litigation and contingencies, as well as our expectations of the amount of revenue to be recognized, as additional information becomes available, and adjust these estimates as necessary. We could experience a reduction in our profitability, cash flows and liquidity if we do not properly estimate the amount of required accruals for litigation or contingencies, if we do not recognize the appropriate amount of revenue related to such matters, 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 and other legal proceedings is difficult to assess or quantify, as such proceedings may involve very large or indeterminate amounts and the magnitude of the potential loss or recovery may remain unknown for substantial periods of time. Furthermore, because litigation and other legal proceedings are 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, divert management’s attention, 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.
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, our operating results, our data security or our reputation.
We are heavily reliant on information and communications technology, computers and other 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. We maintain certain information about our customers, vendors, subcontractors, employees and other parties, all of which expect that we will adequately protect such information. 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, including those associated with acquired businesses, and our operations could be damaged or interrupted by cyberattacks and/or physical security risks. These risks include natural disasters, power loss, telecommunications failures, intentional or inadvertent user misuse or error, failures of information technology solutions, computer viruses, phishing attacks, social engineering schemes, malicious code, ransomware attacks, data extortion, 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 cyberattacks could go unnoticed for some period of time.
24
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 company information, and could delay or prevent operations, including the processing of transactions and reporting of financial results or cause processing inefficiency or downtime. In addition, the rapid evolution and increased adoption of artificial intelligence technologies may intensify our cybersecurity risks. 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 cyberattack, 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, all of which could result in significant costs, fines or litigation and have a material adverse effect on our business, results of operations and financial condition.
In the ordinary course of business, we and third-parties on whose systems we rely have been targeted by malicious cyberattacks, although our systems have been sufficiently resilient to prevent disruption of our operations. However, while we have not experienced a material cybersecurity incident nor incurred material breach related expenses during the reporting period, because the techniques used to obtain unauthorized access or sabotage systems change frequently and are generally 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.
In addition, the U.S. federal government has continued to raise concerns about the heightened potential for cyberattacks from nation-states and decentralized cybercriminal groups. As cyberattacks continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures to protect against the threat of system disruptions and security breaches, and to investigate and remediate any information security vulnerabilities and mitigate problems caused by any such 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.
We regularly evaluate the need to upgrade, enhance 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, including due to the rapid evolution and increased adoption of artificial intelligence and machine learning technologies, as well as considerations related to hybrid work models, under which employees can work and access the Company’s technology infrastructure remotely. 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, the implementation of new systems may not result in productivity improvements at the levels anticipated. System implementation and/or any other information technology disruptions, if not anticipated and appropriately mitigated, could have an adverse effect on our business and remediation of any such disruptions could result in significant costs.
In addition, the unauthorized disclosure of confidential information and current and future laws and regulations governing data privacy may pose complex compliance challenges and/or result in additional costs. The continuing and evolving threat of cyberattacks has also resulted in increased regulatory focus on risk management and prevention. Compliance with existing and emerging cyber-related regulations or other requirements, including regulations adopted by the SEC, could require significant additional resources and/or cause us to incur significant costs. In addition, these regulations could require us to disclose information about a cybersecurity incident before it has been completely investigated or remediated in full or even in part. Failure to comply with such laws and regulations could result in penalties, fines, regulatory actions and/or legal liabilities and/or harm our reputation, which could have an adverse effect on our results of operations, cash flows and financial condition.
Our subcontractors and suppliers may fail or be unable 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 issue work orders under a subcontracting arrangement. Our ability to fulfill our obligations as a prime contractor could be jeopardized if any of our subcontractors fail to perform the agreed-upon services on a timely basis and/or deliver the agreed-upon supplies. 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 pay our subcontractors for work performed for customers that fail to 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, equipment manufacturers and lessors to obtain or provide the materials and equipment we require to conduct our operations. Any substantial limitation on the availability of suppliers or equipment, including from economic, regulatory or market conditions, such as supply chain disruptions or other factors, could negatively affect, and in the past have negatively affected, our operations and financial results. Climate impacts causing supply shortages, supply chain disruptions or new requirements affecting our suppliers, such as shortages of or restrictions on the use of water, raw materials or energy, or changing waste disposal requirements, could result in operational inefficiencies, impair our ability to complete projects, or cause our operating costs to increase if we are unable to pass such cost increases through to our customers. Additionally, in an environment of elevated or sustained levels of inflation, it can be difficult to find appropriately skilled and qualified subcontractors and suppliers at affordable rates, which has caused our costs to increase. Our costs may continue to increase due to such supply shortages and any related increases in subcontractor and supplier costs if we are unable to pass any such cost increases through to our customers. Any of these factors could have an adverse effect on our results of operations, cash flows and/or liquidity.
25
The use of a unionized workforce and any related obligations could subject us to liabilities that could adversely affect our liquidity, cash flows and results of 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 business operations, financial results, liquidity and cash flows.
Substantially all of our union and collective bargaining agreements require us to participate with other companies in multiemployer pension plans. We may be subject to substantial liabilities in the event of a complete or partial withdrawal from, or upon termination of, an underfunded U.S.-registered multiemployer pension plan, which are governed by the Employee Retirement Income Security Act ("ERISA"), as amended. Under such circumstances, the current laws pertaining to multiemployer plans would require participating employers to make payments to the plan for their proportionate share of the multiemployer plan’s unfunded vested liabilities, including an allocable share of the unfunded vested benefits of the plan for all plan participants. As a result, participating employers may bear a higher proportion of liability for unfunded vested benefits if the other participating employers cease to contribute to, or withdraw from, the plan. The allocable portion of liability of participating employers could be disproportionately greater if employers that have withdrawn from the plan are insolvent, or if they otherwise fail to pay their proportionate share of the withdrawal liability. In addition, the Pension Protection Act of 2006, as amended, requires underfunded pension plans to improve their funding ratios within prescribed intervals, 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 can 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, 2025, several of the multiemployer pension plans in which we participate are underfunded and, as a result, we could have potential liability associated with a voluntary or involuntary withdrawal from, or termination of, these plans, or we could be required to increase our contributions. 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. Although we do not have current plans to withdraw from any of the multiemployer pension plans in which we participate and are not aware of circumstances that would reasonably lead to material claims against us in connection with these plans, we could be assessed withdrawal liabilities, or we could be required to pay increased contributions and/or excise taxes in the future, any of which could adversely affect our cash flows, liquidity and results of operations.
We may have additional tax liabilities associated with our 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, and could have a material adverse effect on our results of operations, cash flows and liquidity.
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. 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.
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, including with respect to integration of the significant acquisition activity we have completed over the past few years. 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. See Item 9A. “Controls and Procedures,” for related discussion.
Risks Related to Strategic Transactions and Foreign Operations
Acquisitions and strategic investments involve risks, including from integration of acquired businesses into our operations, which, if unsuccessful, could negatively affect our operating results, cash flows and liquidity and may not enhance shareholder value.
We have made, and may continue to make, strategic acquisitions and investments that may expose us to operational challenges and risks, including: (i) the ability to profitably manage the acquired business or successfully integrate the operations, internal controls, procedures, financial reporting and accounting systems of the businesses we acquire into our business operations; (ii) the ability to realize the anticipated benefits from successful integration of the acquired businesses; (iii) increased indebtedness, contingent earn-out obligations and/or other liabilities; (iv) the ability to fund cash flow shortages that may occur if anticipated revenue, profits and/or cash flows are not realized or are delayed, whether by general economic or market conditions, or other unforeseen difficulties; (v) the expense of integrating acquired businesses; (vi) the ability to retain or hire the personnel required for the successful operation of the acquired business and expanded business operations, in general; (vii) the ability to maintain business relationships and institutional knowledge by retaining, or effectively transitioning, key leadership roles and management teams of the
26
acquired business; (viii) diversion of management’s attention; and (ix) the availability of funding sufficient to meet increased capital needs, among others.
Acquired companies may have liabilities that we failed, or were unable to discover in the course of performing due diligence reviews. 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. Additionally, purchase agreements for certain acquisitions may not contain indemnification provisions, which would fully expose us to legacy liabilities of the related acquired business. We may learn additional information about the businesses we have acquired that could materially and adversely affect us, such as unknown or contingent liabilities, unprofitable projects, litigation-related liabilities 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. We generally require that key management and former principals of the businesses we acquire enter into non-competition agreements in our favor. If we are unable, or the courts refuse, to enforce the non-competition agreement entered into by such person or persons, we might be subject to increased competition. 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 may pay for acquisitions or strategic investments with increased borrowings under our credit facility or through the issuance of debt instruments, which could result in higher levels of indebtedness and negatively affect our ability to service our debt within the scheduled repayment terms, or our ability to remain in compliance with our debt covenants and to maintain our investment grade credit rating. Additionally, from time to time, we may pay for acquisitions with shares of our common stock, which could dilute the ownership interests of our common shareholders. 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. We may decide to pursue acquisitions with which our investors may not agree. In addition, 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 have incurred substantial expenses in connection with the integration of the operations, practices, policies and procedures of past acquisitions that required significant acquisition and integration efforts, which negatively affected our results of operations, cash flows and liquidity. Our results of operations and cash flows could be negatively affected in the future if we continue to acquire additional businesses requiring significant acquisition and integration efforts.
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 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. Additionally, the structure of these arrangements can create inherent conflicts of interest regarding commercial terms, such as the pricing of construction services, the approval of change orders, and the resolution of claims. While we seek to minimize these conflicts of interest through the terms set in the agreements for these investments, as well as processes in place to manage these relationships, any failure to adequately manage a potential conflict of interest, or the perception of a conflict, could damage our relationships with investment partners, result in litigation, or harm our professional reputation.
Further, if our partners do not meet their performance obligations on projects, and we are unable to adequately address such performance issues on the part of our partners, 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 adversely affect our results of operations, cash flows and liquidity. 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 our investees to complete certain transactions, could subject us to a loss of some or all of the value of our investment. See Note 4 - Fair Value of Financial Instruments and Note 15 - Commitments and Contingencies in the notes to the audited consolidated financial statements, which are incorporated by reference, for additional information.
Our operations in international markets, or future efforts to expand 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 small portion of our revenue from international markets. In the future, we could further expand the volume of international services we provide, as well as the foreign geographic territories in which we operate. See Note 14 - 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 in the past and may expand our foreign operations in the future. Economic conditions, including those resulting from geopolitical shifts, civil unrest, acts of terrorism, wars and other conflicts, public health matters 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 such 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
27
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, and 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. 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 could incur severe criminal or civil penalties or other sanctions 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, which could adversely affect our reputation, business, results of operations and cash flows.
Risks Related to Regulation and Compliance
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, we may be liable for significant fines and damages, and we 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.
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 could result in new or increased liabilities that could have a material adverse effect on our results of operations, cash flows and liquidity. 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, which could adversely affect our business.
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, fuel storage, air quality and the protection of endangered species. 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 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. Such claims may arise, for example, out of current or former conditions at project sites, including legacy matters from acquired businesses, current or former properties owned or leased by us, or contaminated sites that have always been owned or operated by third parties. For example, we 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. 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. The obligations, liabilities, fines and costs or reputational harm associated with these and other events could be material and could have a material adverse impact on our business, financial condition, results of operations and cash flows.
Our failure to comply with federal, state and local agencies that oversee compliance with safety and transportation regulations 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, and 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 from violations of health and safety regulations, including, in extreme cases, criminal sanctions. We could suffer reputational harm and our customers could cancel existing contracts and not award future business to us if we were in violation of these regulations. 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. Our ability to service our customers could be damaged if we were not able to successfully resolve such issues, which could lead to a material adverse effect on our results of operations, cash flows and liquidity.
We are subject to climate-related risks and risks associated with rapidly evolving regulatory and stakeholder focus and any related reporting obligations with respect to sustainability matters.
Regulatory requirements and stakeholder expectations with respect to sustainability matters, including matters relating to a changing climate, are rapidly evolving. While the potential effects of climate change are highly uncertain, climate change and climate-related events could result in, among other things, an increase in extreme weather events, such as floods, hurricanes and wildfires, as well as changes in rainfall patterns, storm patterns and intensities and temperature levels, rising sea levels and limitations on water availability and quality. Our operating results are significantly influenced by weather; therefore, major changes in weather patterns could have a significant effect on our future operating results.
28
Natural catastrophes or other extreme weather events could cause supply chain disruptions, resulting in shortages of construction or other materials, or limit the availability of resources, which could impair our ability to complete projects, increase the costs of our projects, reduce productivity, or could cause projects to be delayed or canceled. Severe weather events could also damage ongoing construction projects and lead to increased costs. We could experience project cancellations, reduced demand or reduced productivity if climate change results in a significant increase in adverse weather conditions in a given period, or from potential market-related or macroeconomic effects of climate-related factors that affect our business, which could negatively affect our revenue and profitability.
We could also be exposed to increased risk of liability in locations potentially affected by climate-related risks, for example, in areas where the risk of wildfires is increased. The risks associated with the physical effects of climate change have affected, and could continue to negatively affect, our insurance costs or the amount of coverage that insurers are willing to make available under our insurance policies. An increase in severe weather events and changes in climate patterns could cause insurers to increase our premiums, limit our coverage or add exclusions to policies, including for wildfire, hurricane or other climate-related risks. Any of these factors could increase our risk exposure and our cost of insurance coverage in the future, which could negatively affect our business and cause us to incur additional expenses, or could require us to increase our reliance on self-insurance.
Climate impacts could negatively affect our or our customers’ operations from damage to properties, assets or locations associated with projects in backlog, causing projects to be delayed or canceled. Climate impacts could also result in decreased availability of, or limitations on access to, clean water or other natural resources in the communities where we conduct our operations, which could disrupt our or our customers’ operations and result in work stoppages, project delays, reduced productivity and increased costs. All of the above climate-related factors could negatively affect our business, financial condition and results of operations.
Climate-related factors could also affect the projects our customers award. Concerns about climate change could result in new regulations, regulatory actions or requirements related to energy efficiency or reductions in GHG emissions, any of which could negatively affect our customers, or decrease the number, scope or types of projects they award, which could decrease demand for our services. Demand for power projects, underground pipelines or other projects could be negatively affected by significant changes in weather or by climate-related legislation or regulations. Changing customer preferences, including changes in demand for hydrocarbon or clean energy-related products and services, or negative effects from social or political activism, including public protests or local opposition to projects, could cause project delays or cancellations, increase our costs, or negatively affect demand for our services. Additionally, a transition of existing service offerings to alternative, lower carbon offerings could result in lower revenue and/or reduced levels of profitability.
Legislative and/or regulatory responses related to climate change could also affect the availability of goods, increase our costs or otherwise negatively affect our operations. In addition, demand for our services could be negatively affected by market and consumer response to climate-related matters, new or changing compliance obligations of our customers, changes in technology, and changes in our customers’ expectations and/or requirements for companies in their supply chains, which have affected, and could continue to affect, their selection of service providers or require those in their supply chain to meet certain climate and/or sustainability-related goals or disclosure requirements, which could also increase our costs. Our ability to compete could also be affected by labor shortages resulting from lack of available skilled labor for new or emerging climate-related technologies. Additionally, if our stakeholders, including our customers, do not have a favorable view of our values and practices with respect to climate and/or sustainability-related matters, we could suffer reputational risk and reduced demand for our services, or an increase in our cost of, or a reduction in the availability of, capital.
U.S. and international regulators, investors and other stakeholders have been focused on sustainability matters in recent years. For example, certain domestic and international laws and regulations relating to sustainability matters, including environmental sustainability, climate change, human rights and human capital management have been adopted or are under consideration, some of which include specific, target-driven disclosure requirements or obligations. Sustainability-related reporting and compliance requirements have increased our costs, including from increased investment in technology, expertise and implementation of new reporting processes. The above described effects of such regulations, as well as exposure to the risk of non-compliance and potential diversion of operational and/or management attention, could increase our costs and negatively affect our business, results of operations and cash flows. Environmental regulations and policies to encourage the use of clean energy technologies and regulate emissions of GHG to address climate change could cause uncertainty for our customers and our operations. In addition, the current presidential administration, combined with Republican Party majorities in both the U.S. House of Representatives and Senate, has created regulatory uncertainty with respect to climate change policy. For example, on January 20, 2025, President Trump signed an executive order to withdraw the United States from United Nations Framework Convention on Climate Change, marking a significant shift in U.S. climate policy, and effective as of January 27, 2026, the United States has withdrawn from the Paris Agreement. Such shift in U.S. climate policy continued during fiscal year 2025 and is expected to continue under current leadership. It remains unclear what further actions the federal government may take with respect to domestic and international regulations, programs and initiatives that could affect demand for or the economic viability of renewable energy infrastructure.
We cannot predict future changes to environmental regulations and policies, nor can we predict the effects that any such changes would have on our business. The establishment of rules limiting GHG emissions or mandating lower carbon infrastructure could affect overall customer demand, reduce the need for certain of our services and/or 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 GHG emissions, or if we were otherwise required to undertake carbon emission reduction efforts, we could experience a significant increase in environmental compliance costs considering our large fleet and the amount of construction machinery we own. New regulations requiring us to acquire different equipment or change processes could result in an impairment of our current fleet or other equipment assets. Additionally, such new equipment may not be available, or we may not be able to purchase or rent this equipment in a cost-effective manner. Required investment in new technologies or adoption of new practices and processes to reduce our carbon emissions could increase our costs and reduce our profitability.
Compliance with any new laws or regulations relating to the reduction of GHG could result in significant required changes to our operations and a significant increase in the cost of conducting our business. In addition, our reputation could suffer and/or we could experience a
29
reduction in the amount of future work we are awarded if our operations are perceived to result in high levels of GHG emissions or to otherwise pose environmental risks. Reductions in project awards, project deferrals, delays or cancellations, or increases in costs related to the effects of climate change, climate change initiatives or climate change regulations could have a material adverse effect on our results of operations, cash flows and liquidity.
Stakeholder expectations with respect to sustainability matters have been rapidly evolving and expanding. If we do not adapt to or comply with stakeholder expectations and standards as they continue to evolve, or if we are perceived to have not responded appropriately or quickly enough to growing concerns related to sustainability and climate-related matters, regardless of whether there is a regulatory or legal requirement to do so, we could experience a loss of business and be unable to attract and retain customers and talented personnel, or we could face an increase in sustainability or climate-related litigation and suffer reputational damage, all of which could adversely affect our business, results of operations and financial condition, and could result in an increase in our cost of capital and/or a decline in the price per share of our common stock.
Additionally, from time to time, we establish strategies and expectations relative to sustainability matters. Our ability to achieve any such strategies or expectations is subject to numerous factors and conditions, many of which are outside of our control. Failures or delays in achieving our strategies or expectations, whether actual or perceived, could adversely affect our business, operations and reputation, and could increase our risk of litigation.
In addition, our continuing efforts to research, establish, accomplish and accurately report on our sustainability strategy and efforts may create operational risks, increase our expenses and expose us to reputational, legal and other risks. Some of the statements in our voluntary disclosures regarding sustainability matters may be based on hypothetical expectations and assumptions that may or may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are uncertain and could be inaccurate or subject to misinterpretation given the nature of the disclosures and commitments and the difficulty in identifying, measuring and reporting on such sustainability matters.
Risks Related to Financing Our Business
We have a significant amount of debt, including variable rate indebtedness, which could adversely affect our business, financial condition and results of operations, and our ability to access capital markets in the future. In addition, our debt contains restrictive covenants that may prevent us from engaging in transactions that might benefit us.
Our outstanding debt and debt service requirements could have significant consequences on our future operations, including: making it more difficult for us to meet our debt-related payment and other obligations; an event of default if we fail to comply with the financial and other restrictive covenants contained in our debt agreements, which 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 limiting our ability to obtain additional financing for these purposes; limiting our flexibility in planning for, or reacting to, changes in our business, the industries in which we operate, and the general economy; and placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged.
Additionally, our variable rate indebtedness subjects us to interest rate risk. Although the Federal Reserve lowered short-term interest rates in 2025, interest rate volatility, particularly increases to interest rates, will increase our debt service obligations even if the principal amount borrowed remains the same, which would negatively affect our results of operations, cash flows and liquidity. See Item 7A. “Quantitative and Qualitative Disclosures About Market Risk - Interest Rate Risk,” which is incorporated by reference, for further information about our debt subject to variable interest rates. Furthermore, if our credit rating is downgraded, it could increase borrowing costs on our variable rate indebtedness, and/or increase the cost of renewing or obtaining new debt financing or make it more difficult to renew, obtain or issue new debt financing in the future. 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. Should we be unable to comply with the terms and covenants of our indebtedness, including our credit facility, we would be required to obtain consents from our lenders, modify our credit facility or other debt instruments, 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. 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 ability to meet our payment and other obligations under our debt instruments depends on our ability to generate significant cash flow in the future, which can be subject to many factors, some of which are beyond our control. We cannot assure you that our business will generate future cash flow from operations, or that future borrowings will be available to us in an amount sufficient to enable us to meet our payment obligations and fund other liquidity needs. Our business is capital intensive, and 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 could have terms that are unfavorable or could be highly dilutive. Our ability to obtain additional financing or to refinance our existing indebtedness will depend on the capital markets and our financial condition at such time. Any of the above factors could adversely affect our results of operations, cash flows and liquidity.
We may be unable to obtain sufficient bonding capacity to support certain service offerings, and the need for performance and surety bonds 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 or for individual self-insurance programs 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, we may be unable to compete for or work on projects that require bonding.
30
Risks Related to 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 and could dilute the ownership interests of our shareholders and/or lead to volatility in our common stock price.
We are not restricted from issuing additional common stock. Our Amended and Restated Articles of Incorporation provide that we may issue up to a total of 145.0 million shares of common stock, of which approximately 78.9 million shares were outstanding as of December 31, 2025. We grow our business organically as well as through acquisition. Occasionally, we may issue shares of stock as consideration in our acquisitions, and, typically, we have the option to issue shares of our common stock as consideration for future earn-out obligations. The issuance of additional shares of our common stock in connection with future acquisitions, financing transactions, share-based payment awards or other issuances of our common stock would dilute the ownership interest of our common shareholders. Sales of a substantial number of shares of our common stock or other equity-related securities in the public market could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity or equity-linked securities. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock.
The market price of our common stock has been, and may continue to be, highly volatile.
The market price of our common stock on the 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, our expectations of future operating results, or the operating results of our competitors; market conditions in our customers' industries, including the capital spending plans of our significant customers; announcements of new or terminated customers or contracts; announcements of acquisitions by us or our competitors; volatility in energy and fuel prices; changes in recommendations or earnings estimates by securities analysts; announcements of share repurchase programs, or activity under existing repurchase programs; and issuances of our common stock or other securities, including in connection with acquisition or financing transactions. In addition, the stock market continues to experience significant volatility, which can sometimes be 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.
Additionally, we have repurchased shares of our common stock in the past, including for the year ended December 31, 2025, and may continue to do so in the future. We cannot provide assurance that any stock repurchases will enhance shareholder value because the market price of our common stock may decline below the levels at which we repurchased such shares.
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, 2025. 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 could 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 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 would take at least two annual shareholder meetings to effect a change in control of our Board of Directors, which could 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 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.

ITEM 1C. CYBERSECURITY
Risk Management and Strategy
Cybersecurity risk management is an important part of MasTec's overall risk management efforts. We maintain a comprehensive enterprise-wide information security program that comprises policies and controls designed to identify, safeguard against, detect, respond to, mitigate and manage reasonably foreseeable cybersecurity risks and threats. Our approach utilizes diverse security tools to prevent, identify, investigate, resolve and recover from vulnerabilities and security incidents. These include, but are not limited to, internal reporting, monitoring and detection tools.
31
We regularly collect data on cybersecurity threats and risk areas and conduct periodic external penetration and other tests to assess the effectiveness of our processes and procedures. We assess risks associated with third-party providers as part of our overall cybersecurity risk management framework by reviewing system and organization controls reports, when available, and other independent reports. We also generally require third parties to, among other things, maintain security controls to protect our confidential information and to promptly notify us of material breaches that may impact our data.
We face cybersecurity threats in the ordinary course of our business and have experienced cybersecurity threats and breach attempts in the past. Such threats and breach attempts have not materially affected our business, strategy, results of operations or financial condition. At any given time, however, we may face known or unknown cybersecurity risks and threats that cannot be fully prevented or mitigated, and we may discover vulnerabilities in our cybersecurity programs. Therefore, we may not be successful in preventing or mitigating a cybersecurity incident that could have a material adverse effect on us. For more information on the cybersecurity risks we face, please refer to “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, our operating results, our data security or our reputation.” in Item 1A. “Risk Factors.”
Governance
Our CISO routinely informs our CIO, Chief Financial Officer and other members of management, as appropriate, about threats, including assessments of threat levels, trends, incidents and related remediation plans, including matters related to the prevention, detection and remediation of any incidents in accordance with our cybersecurity program.
Our Board of Directors has oversight of our enterprise risk assessment and risk management processes, as well as the steps taken to mitigate these risks, including for cybersecurity matters. The Audit Committee of our Board of Directors has oversight of cybersecurity risk assessment and risk management policies as part of its risk management oversight responsibilities, and is responsible for ensuring that the Company has processes in place to identify, evaluate and manage cybersecurity risks, as well as appropriate processes and programs to mitigate cybersecurity incidents if they occur. The Audit Committee actively engages in cybersecurity risk discussions and receives periodic updates on the Company's cybersecurity program from our CISO, including updates on various cybersecurity matters such as risk assessments, threats, incidents, prevention, detection and remediation of incidents, mitigation strategies, areas of emerging risk and industry trends, among other topics. Significant cybersecurity matters, including those related to incidents, are escalated to the Board of Directors.
ITEM 2. PROPERTIES
Our operations are conducted from different locations, primarily within the United States and Canada, including our corporate headquarters located in Coral Gables, Florida. Substantially all of these properties, including our corporate headquarters, are leased facilities, none of which is material to our operations. We believe that our existing facilities are adequate for our current and planned levels of operation.
ITEM 3. LEGAL PROCEEDINGS
The information set forth in Note 15 - Commitments and Contingencies in the notes to the audited consolidated financial statements in Item 8 of this Form 10-K is incorporated by reference.
MasTec has elected to use a $1 million threshold for disclosing proceedings arising under federal, state or local environmental laws, which proceedings involve potential monetary sanctions, and in which a governmental authority is a party. MasTec believes proceedings under this threshold are not material to its business and financial condition.
ITEM 4. MINE SAFETY DISCLOSURES
The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95.1 to this Annual Report on Form 10-K.

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.”
General Economic, Market and Regulatory Conditions
We have experienced, and may continue to experience, direct and indirect negative effects on our business and operations from economic, market and regulatory conditions, including the level of interest rates; inflationary effects on the costs of labor, materials and fuel; supply chain disruptions; uncertainty related to the implementation and pace of spending under governmental programs and initiatives related to infrastructure and other industrial investment, delays and uncertainty related to project permitting and/or other regulatory matters or uncertainty; climate, environmental and sustainability-related matters; changes in technology, tax and other incentives; potential market volatility that could negatively affect demand for future projects, and/or delay existing project timing or cause increased project costs; and public health matters. Additionally, the effects of ongoing geopolitical events that are outside of our control, could potentially increase volatility and uncertainty in the energy and capital markets, which could delay projects and/or negatively affect demand for future projects.
During the year ended December 31, 2025, the U.S. government announced or imposed a variety of tariff or other trade actions, in response to which many countries have announced retaliatory trade actions, including tariffs on U.S. exports or bans by foreign countries on certain of their exports. These actions have increased the cost of importing certain construction materials into the U.S., including steel, concrete, copper and solar panels, and have caused disruption and uncertainty to both international trade and supply chains, in turn affecting project demand and timing. More recently, on February 20, 2026, the U.S. Supreme Court ruled that certain trade tariffs imposed by the U.S. federal government under the IEEPA were unconstitutional. Following the U.S. Supreme Court’s decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. Significant uncertainty remains regarding the status of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended. While the duration, extent and effects of these tariffs and trade actions cannot be predicted with certainty, these policy changes could impact our ability to execute projects and have a material adverse effect on our business, financial condition, and results of operations.
Further, on July 4, 2025, OBBBA was signed into law in the United States increasing federal support for oil and gas production while reducing support for renewable energy and infrastructure. Notably, the OBBBA accelerates the phaseout of certain clean energy tax credits established under the IRA, including the clean electricity investment and clean energy production credits for solar and wind projects, which may reduce longer term demand for such projects. Under the new provisions, these credits will no longer be available for projects placed in service after December 31, 2027, unless construction begins on or before July 4, 2026, pursuant to a grandfathering rule. Projects that qualify under this rule must still meet continuity requirements to remain eligible. At the same time, the OBBBA contains other provisions to incentivize oil and gas development as well as to support energy infrastructure such as carbon capture and energy storage. The OBBBA, along with other evolving trade and immigration policies, may have both positive and negative effects on our business, including, but not limited to, shifts in the timing, type and scope of customer projects, fluctuations in demand for our services, and changes in capital and labor costs, including availability.
The extent to which general economic, market, political and regulatory conditions could affect our business, operations and financial results is uncertain as it will depend upon numerous evolving factors that we may not be able to accurately predict, and, therefore, any future impacts on our business, financial condition and/or results of operations cannot be quantified or predicted with specificity.
We believe that our financial position, cash flows and operational strengths will enable us to manage the current uncertainties resulting from general economic, market and regulatory conditions. We carefully manage our liquidity and monitor any potential effects from changing economic, market and regulatory conditions on our financial results, cash flows and/or working capital and will take appropriate actions in efforts to mitigate any impacts.
Business
See Item 1. “Business” for discussion pertaining to our business and reportable segments.
We seek to grow and diversify our business both organically and through acquisitions and/or strategic arrangements in order to deepen our market presence and customer base, broaden our geographic reach and expand our service offerings. In 2021, we initiated a significant transformation of our end-market business operations to position us for expected future growth opportunities. This transformation included significant business combination activity, including expansion of our scale and capacity in renewable energy, power delivery, heavy civil and telecommunications services, which resulted in significant acquisition and integration costs in subsequent periods. Although acquisitions continue to be an element of our growth strategy, the integration activities related to the transformation-related acquisitions were completed in the fourth quarter of 2023.
Recent acquisitions. Subsequent to December 31, 2025, we completed one acquisition of an infrastructure services company that specializes in water and wastewater distribution networks in the south central region of the United States, which will be included within our Clean Energy and Infrastructure segment.
During 2025, we completed five acquisitions, which included all of the equity interests of the following: (i) within our Communications segment: a telecommunications construction company, which acquisition was effective in July; (ii) within our Pipeline Infrastructure segment: a construction company specializing in roadway infrastructure, which acquisition was effective in August; and (iii) within our Clean Energy and Infrastructure segment: a construction company specializing in construction management and design-build services, which acquisition was effective
35
in December. Additionally, we acquired certain operations and assets of a business specializing in install-to-the-home services included within our Communications segment, effective in November, and, effective in July, we acquired certain of the assets of an equipment company, which is included within our Pipeline Infrastructure segment.
During 2024, we completed three acquisitions, including, within our Power Delivery segment, all of the equity interests of a construction company focused on underground utility infrastructure for industrial and municipal projects, with expertise in data center utility systems; certain operations of a heavy civil contractor specializing in transportation projects, which acquisition was included within our Clean Energy and Infrastructure segment; and, within our Pipeline Infrastructure segment, the acquisition of the equity interests of a company focused on pipeline infrastructure and heavy civil projects. In connection with the acquisition within our Pipeline Infrastructure segment, we acquired 60% of the equity interest of the company in exchange for consideration transferred of cash and a 40% equity interest in a MasTec Canadian subsidiary.
During 2023, we completed four acquisitions including, within our Communications segment, certain of the assets of a telecommunications company specializing in wireless services; and a telecommunications construction company specializing in broadband and fiber-to-the-home initiatives in the New England area. Additionally, we acquired certain of the equity interests of two equipment companies, both of which are included within our Pipeline Infrastructure segment.
For additional information, see Note 3 - Acquisitions, Goodwill and Other Intangible Assets, Net 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, industry and market conditions on our customers, including the potential effects of the factors discussed above in “General Economic, Market and Regulatory Conditions,” which can affect demand for our customers’ products and services and can increase or decrease our customers’ planned capital and maintenance budgets in certain end-markets. Any of these factors and effects, as well as mergers and acquisitions or other business transactions among the customers we serve, could affect demand for our services, or the cost to provide such services and our profitability.
Changes in demand in our customers’ businesses and fluctuations in market prices for energy sources, including oil and gas products, can affect demand for our services. In particular, such changes can affect the level of activity in energy generation projects, including from renewable energy sources, as well as pipeline construction and carbon capture projects. The availability of transportation and transmission capacity can also affect demand for our services, including energy generation, electric grid and pipeline construction projects. These factors, as well as the highly competitive nature of our industry, can result in changes in levels of activity, project mix, and/or the profitability of the services we provide. We strive to maintain our profit margins through productivity improvements, integration and cost reduction programs and/or business streamlining efforts when operating under conditions of increased pricing pressure or other market developments. Market factors, including elevated rates of interest and inflation and the related effects on labor, materials and fuel costs, have had, and could continue to have, a negative effect on our profitability, to the extent that we are not able to pass these costs through to our customers. While we actively monitor economic, industry and market factors that could affect our business, we cannot predict the effect that changes in such factors could have on our future results of operations, liquidity and cash flows, and we may be unable to fully mitigate, or benefit from, such changes. See Item 1. “Business” under “Industry Trends” and Item 1A. “Risk Factors” under “Unfavorable market conditions, including elevated levels of inflation and/or interest rates, supply chain disruptions, political regulatory or market uncertainty, including economic downturns and heightened geopolitical tensions and conflicts, could reduce capital expenditures in the industries we serve or could adversely affect our customers and result in decreased demand for our services.” for discussion pertaining to opportunities in the industries we serve and potential effects of market conditions.
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 customer spending patterns, bidding seasons, project schedules, weather and/or climate-related effects, holidays, regulatory matters and/or timing, in particular, for large non-recurring projects, and the effects of market uncertainty or disruptions, as described within “Economic, Industry and Market Factors,” above.
Our revenue is generally lower at the beginning of the year and during the winter months because harsher weather, such as cold, snowy or wet conditions, can delay projects. 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 project activity and/or 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 can have a positive effect on our revenue. Customers, however, could also curtail certain of their project activities toward the end of the year as they await capital budget allocations for the next year. The holiday season and inclement weather can cause delays, which can reduce revenue and increase costs on affected projects during the related period. Any quarter may be positively or negatively affected by adverse or unusual weather patterns and/or climate-related effects, including warm winter weather, excessive rainfall, flooding or natural catastrophes such as wildfires, hurricanes, excessive winds or other severe weather, making it difficult to predict quarterly revenue and margin variations.
Additionally, our industry can be highly cyclical and may be adversely affected by industry declines, changes or delays in new projects, and/or changes in consumer or customer demand. 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, including from changes in end market customer demand, customer revenue mix, or project timing. 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, including climate-related matters; and acquisitions, dispositions or strategic 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.
36
Understanding Our Results of Operations
Revenue. We primarily 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 employee compensation, including salaries, employee benefits and incentive compensation; certain other employee expenses, including travel and training; subcontracted services; equipment and facility rentals; fuel and other equipment expenses; repairs and maintenance; materials and supplies; insurance expenses; certain legal and settlement matters; and certain other operating expenses. Project profit is calculated by subtracting a project’s costs of revenue, including project-related depreciation, from project revenue. Project profit and corresponding project margins will generally be reduced if actual costs to complete a project exceed our project cost estimates and we are unable to pass the increased costs to our customers. Estimated losses on contracts, or the excess of the total estimated costs to complete a contract over the contract’s total estimated contract transaction price, are recognized in the period in which such losses are determined. Factors impacting our costs of revenue, excluding depreciation and amortization, and project profit, include:
Project Mix. Revenue mix impacts our overall project margins, as margin opportunities and/or risks can vary by project type, industry, and by segment over time. For example, installation work that is performed on a fixed price basis has a higher level of margin opportunity or risk than maintenance or upgrade work, including those under master service and other service arrangements, which is often performed under pre-established fixed price per unit or time and materials pricing arrangements. As a result, changes in project mix between installation work performed on a fixed price basis, and maintenance or upgrade services that are performed under pre-established fixed price per unit or time and materials pricing arrangements, can affect our project margins in a given period.
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. The level of demand for restoration and storm work, which, by its nature, is unpredictable, can also favorably or negatively affect our revenue composition and project margins in a given period. 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 and job conditions, changes in the cost of labor and materials, crew availability, job productivity and work volume. Job productivity can be affected by factors such as quality of the work crew and equipment, the quality of engineering specifications and designs, as well as unanticipated engineering or design challenges, availability of skilled labor, environmental or regulatory factors and customer decisions or delays. Job productivity can also be influenced by weather conditions, job 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 environmental 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 availability and mix of subcontracted resources versus self-perform work can affect our overall project margins.
Material versus Labor Costs. In most 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, changes in the mix of projects with significant materials requirements could affect our overall project margins.
General and Administrative Expense. General and administrative expenses consist principally of employee compensation and benefits, travel expenses and related costs for our finance, treasury, benefits, insurance and risk management, legal, facilities, information technology and executive functions. General and administrative expenses also include non-cash stock-based compensation expense, external professional and accounting fees, certain legal and settlement matters, facilities costs, expenses associated with information technology used in administration of the business, gains or losses from the disposal of property and equipment, acquisition costs, including certain costs related to acquisition integration, business streamlining, and, from time to time, 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 changes to estimated Earn-out accruals, certain legal and other settlements, certain acquisition-related adjustments, gains or losses from, or changes in estimated recoveries from, certain assets, including financial instruments, and certain liabilities, gains or losses arising from transactions not denominated in functional currencies, and certain acquisition and integration costs.
37
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; amortization; interest expense, net; other income or expense; and provision for income taxes;
•earnings before interest, taxes, depreciation and amortization (“EBITDA”) and adjusted EBITDA, as defined in our non-U.S. GAAP financial measures discussion 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 contract liabilities (“DSO”), and days payable outstanding;
•capital expenditures, net of asset disposals, and investment activities;
•interest and debt service coverage ratios; and
•liquidity and cash flows.
Management’s analysis includes detailed discussions and review of its key performance indicators; proposed investments in property and equipment and new business opportunities; acquisition integration and productivity improvement efforts; strategic arrangement opportunities; and working capital and other capital management efforts, among others. Measuring its key performance indicators and other business metrics 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 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 consolidated financial statements and accompanying notes. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances, including the potential future effects of macroeconomic trends and events, such as inflation and interest rate levels; uncertainty from potential market volatility; other market, industry and regulatory factors, including uncertainty related to the implementation and pace of spending under governmental programs and initiatives and project permitting issues, and other regulatory matters or uncertainty; supply chain disruptions; climate-related matters; and global events, such as geopolitical tensions and conflicts, as well as public health matters. These estimates form the basis for making judgments about our operating results 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 could differ materially 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: 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, intangible assets and acquisition-related contingent consideration; self-insurance liabilities; income taxes; 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 a more detailed discussion of our significant accounting policies and critical accounting estimates.
Revenue Recognition
We recognize revenue from contracts with customers when, or as, control of promised services and goods is transferred to customers. The amount of revenue recognized reflects the consideration to which we expect to be entitled in exchange for the services and goods transferred. We primarily recognize revenue over time utilizing the cost-to-cost measure of progress, which best depicts the continuous transfer of control of goods or services to the customer, and correspondingly, when performance obligations are satisfied for the related contracts.
Contracts. We derive revenue primarily from construction projects performed under: (i) master service and other service agreements, which generally 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 may be subject to one or multiple pricing models, including fixed price, unit price, time and materials, or cost plus a markup. Revenue derived from projects performed under master service and other service agreements totaled 44% of consolidated revenue for the year ended December 31, 2025.
Cost estimation processes used for recognizing revenue over time under the cost-to-cost method require management to make significant assumptions and judgments. Total transaction price and cost estimation processes are based primarily on the professional knowledge and experience of our project managers, operational and financial professionals, and other professional expertise, as warranted. Management reviews estimates of total contract transaction price and costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of the
38
estimated amount and probability of 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 the amount of revenue recognized in the period in which the revisions are determined, which revisions 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 estimated based on management’s experience and judgment. For the year ended December 31, 2025, 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, 2024. Changes in recognized revenue, net, as a result of changes in total contract transaction price estimates, including from variable consideration, and/or changes in cost estimates, related to performance obligations satisfied or partially satisfied in prior periods, for the year ended December 31, 2025, positively affected revenue by approximately 0.8%.
Performance Obligations. A performance obligation is a contractual promise to transfer a distinct good or service to a customer. 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.
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 specific 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 discussions, correspondence or preliminary negotiations and past practices with the customer, engineering studies and legal advice 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 recognized as an adjustment to revenue, typically 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, 2025, our contract transaction prices included approximately $229 million of change orders and/or claims for certain contracts that were in the process of being resolved in the ordinary course of our 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, 2025, these change orders and/or claims primarily related to certain projects in our Clean Energy and Infrastructure and Power Delivery segments. We actively engage with our customers to complete the final approval process for such amounts 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 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. Consideration paid generally consists of cash and, from time to time, shares of our common stock, and potential future payments that are contingent upon the acquired business achieving certain levels of earnings in the future, also referred to as “acquisition-related contingent consideration” or “earn-outs.”
We estimate the fair values of our earn-out liabilities using income approaches such as discounted cash flows or option pricing models, both of which incorporate significant inputs not observable in the market (Level 3 inputs), including management’s estimates and entity-specific assumptions, which inputs are evaluated on an ongoing basis. Key assumptions in estimating the fair values of our earn-out liabilities include the discount rate, which, as of December 31, 2025, ranged from 10.5% to 14.3%, with a weighted average rate of 11.1% based on the relative fair value of the respective Earn-out liabilities, and probability-weighted projections of EBITDA. Significant changes in any of these assumptions could result in significantly higher or lower estimated earn-out liabilities.
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 from the date of acquisition 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 of, or an adjustment to the fair values of, acquisition-related assets and liabilities and/or consideration paid, and are referred to as measurement period adjustments. Measurement period adjustments are recorded to goodwill. Other changes to fair value estimates, including those relating to facts and circumstances that occur subsequent to the date of acquisition, are reflected as income or expense, as appropriate. See Note 3 - Acquisitions, Goodwill and Other Intangible Assets, Net in the notes to the audited consolidated financial statements, which is incorporated by reference, for information pertaining to acquisition-related fair value adjustments.
Significant changes in the assumptions or estimates for a particular acquisition or in the underlying acquisition-related valuations, including the expected profitability or cash flows of an acquired business or assumptions related to the existence or amount of the acquired assets or assumed
39
liabilities, could result in materially different estimates of the fair value of net assets acquired for the related acquisition, which could positively or negatively affect our financial results in future periods.
Goodwill and Other Intangible Assets
We have goodwill and other intangible assets that have been recorded in connection with our acquisitions of businesses. Goodwill is not amortized, but instead is tested for impairment at least annually. Other intangible assets are amortized over their useful lives, which are generally based on contractual or legal rights, in a manner consistent with the pattern in which the related benefits are expected to be consumed, or on a straight-line basis if that pattern cannot be reliably determined.
We perform our annual impairment test of goodwill during the fourth quarter of each year, or more frequently if events or circumstances arise which indicate that the fair value of a reporting unit with goodwill is below its carrying amount. 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.
During the first quarter of 2025, certain reporting units within our Communications and Power Delivery operating segments were restructured to more closely align with the segments’ end markets and to better correspond with the operational management reporting structures of both segments. Under both the current and previous reporting unit structures, each of the components within the Communications and Power Delivery operating segments is a reporting unit. For additional details of the restructuring and the related assessment, 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.
Following is a summary of goodwill and other intangible assets, net, by segment as of December 31, 2025:
| Communications | Clean Energy and Infrastructure | Power Delivery | Pipeline Infrastructure | Total | |||||||||||||||||||||||||
| Goodwill (in millions) | $ | 557.0 | $ | 767.5 | $ | 397.2 | $ | 527.3 | $ | 2,249.0 | |||||||||||||||||||
| Percentage of total | 24.8 | % | 34.1 | % | 17.7 | % | 23.4 | % | 100.0 | % | |||||||||||||||||||
| Other intangible assets, net (in millions) | $ | 34.5 | $ | 286.1 | $ | 263.6 | $ | 72.0 | $ | 656.2 | |||||||||||||||||||
| Percentage of total | 5.3 | % | 43.6 | % | 40.2 | % | 11.0 | % | 100.0 | % | |||||||||||||||||||
As part of our annual impairment test of goodwill, we perform a qualitative assessment of our reporting units by examining relevant events and circumstances that could have an effect on a reporting unit’s fair value, such as: macroeconomic trends and events, including levels of inflation, market interest rates and/or supply chain disruptions; industry and/or market conditions, including the potential effects of regulatory and other uncertainties, such as uncertainty related to the implementation and pace of spending under governmental infrastructure programs and initiatives and project permitting issues; financial, competitive and other conditions, including declines in the operating performance of our reporting units, and/or long-term changes in consumer behavior; entity-specific events; and other relevant factors or events that could affect earnings and cash flows.
If, after performing a qualitative assessment, we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we then perform a quantitative impairment test for those reporting units. We estimate the fair value of a reporting unit using a combination of market and income approaches using Level 3 inputs. Under the market approach, the fair values are estimated using published market multiples for comparable companies and applying them to revenue and EBITDA. Under the income approach, a discounted cash flow methodology is 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, market and regulatory conditions; and (iii) the impact of planned business and operational strategies. Assumptions used in our quantitative goodwill impairment tests are reflective of the risks inherent in the business models of the applicable reporting units and within the units’ industry. Estimated discount rates are 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.
For the year ended December 31, 2025, we completed our annual impairment test of goodwill as part of which we performed a qualitative assessment of all reporting units and concluded that it was more likely than not that the fair value of each reporting unit was greater than its carrying value. Accordingly, a quantitative goodwill impairment test was not required for any of our reporting units, and no goodwill impairment was recognized in 2025.
As of December 31, 2025, we believe that the recorded balances of goodwill and other intangible assets are recoverable; however, adverse changes in the assumptions or estimates used in our analyses, such as a reduction in profitability and/or cash flows, changes in market, regulatory or other conditions, including decreases in project activity levels and/or the effects of elevated levels of inflation, interest rates or other regulatory or market disruptions, including from geopolitical events and/or changes in asset characteristics, could result in non-cash goodwill and/or intangible asset impairment charges in future periods.

Self-Insurance
We are self-insured up to the amount of our deductible for our insurance policies. We also manage certain of our insurance liabilities indirectly through our wholly-owned captive insurance company, which reimburses claims up to the applicable insurance limits. 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. These insurance liabilities are, however, difficult to assess and estimate due to many factors, the effects of which are often unknown or difficult to estimate, including the severity of an injury or an incident, the determination of our liability in proportion to other parties and the number of incidents not reported. Accruals are based upon known facts, historical trends and claims experience, loss development patterns and other actuarial assumptions. Although we believe such accruals are adequate, a change in experience or actuarial or management assumptions could materially affect our results of operations in a particular period. As of December 31, 2025, MasTec’s estimated gross liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled $306.8 million.
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 management’s 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 accurate 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. See Note 13 - 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 accurate 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 materially affect our results of operations, cash flows and liquidity in the related 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 our previous estimates, which could materially affect our results of operations in a given period.
2026 Outlook
We believe that we are at the intersection of transformative trends and are well-positioned to benefit from significant market opportunities in each of our business segments. Please see Item 1. “Business - Industry Trends” for additional information on the outlook for the industries we serve and a detailed discussion of our market opportunities. Our future 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.

Comparison of Years Ended December 31, 2025 and 2024
Revenue. On a consolidated basis, revenue increased by $1,996 million driven by our segment results as follows: revenue increased in our Communications segment by approximately $815 million, or 32%, in our Clean Energy and Infrastructure segment by approximately $607 million, or 15%, in our Power Delivery segment by approximately $563 million or 16%, and in our Pipeline Infrastructure segment by approximately $4 million, remaining generally flat as compared with the prior year. See “Analysis of Revenue and EBITDA by Segment” below for additional information and discussion related to segment revenue.
Costs of revenue, excluding depreciation and amortization. Higher levels of revenue contributed an increase of $1,732 million in costs of revenue, excluding depreciation and amortization, and reduced productivity contributed an increase of approximately $99 million. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue increased by approximately 70 basis points to 87.5% of revenue in 2025 compared to 86.8% of revenue in 2024. The basis point increase was due to a combination of reduced project efficiencies and project mix, primarily within our Pipeline Infrastructure and Power Delivery segments, offset, in part, by improved productivity and efficiencies within our Clean Energy and Infrastructure segment. See “Analysis of Revenue and EBITDA by Segment” below for discussion of operating capacity effects by segment.
Depreciation. As a percentage of revenue, depreciation decreased by approximately 90 basis points, due primarily to a net reduction related to a change in the depreciable lives of certain machinery and equipment to better align the respective assets’ lives with their expected useful lives, offset, in part, by higher capital expenditures to support operational growth and the replacement of older machinery and equipment.
Amortization of intangible assets. The decrease in amortization of intangible assets was due to a combination of the effects of timing of amortization for certain assets and the completion of amortization for certain intangible assets associated with prior years’ acquisitions. As a percentage of revenue, amortization of intangible assets decreased by approximately 20 basis points as compared with the same period in 2024 primarily due to higher levels of revenue.
General and administrative expenses. The increase in general and administrative expenses was due primarily due to an increase in professional fees, the effects of timing of ordinary course legal matters, and a decrease in gains on sales of assets, net, offset, in part, by a decrease in the provision for credit losses. Overall, general and administrative expenses decreased by approximately 60 basis points as a percentage of revenue for the year ended December 31, 2025 as compared with the same period in 2024 due to higher levels of revenue.
Interest expense, net. The decrease in interest expense, net, resulted primarily from lower average balances and, to a lesser extent, lower average interest rates on our variable rate debt, which accounted for a reduction of approximately $35 million, offset, in part by an increase in interest expense from our senior notes due to higher average balances including from the June 2024 issuance of our 5.900% Senior Notes, and, to a lesser extent, from finance leases due to higher levels of activity. See “Financial Condition, Liquidity and Capital Resources” discussion below for details of our debt instruments.
Equity in earnings of unconsolidated affiliates. For the years ended December 31, 2025 and 2024, equity in earnings from unconsolidated affiliates, net, totaled approximately $32 million and $30 million, respectively, and related primarily to our investments in the Waha JVs.
42
Loss on extinguishment of debt. We incurred a loss on debt extinguishment of approximately $11 million for the year ended December 31, 2024 in connection with the second quarter 2024 repayment of our 6.625% IEA Senior Notes and Three-Year Term Loan Facility.
Other (income) expense, net. For the year ended December 31, 2025, other income, net, included approximately $3 million of income, net, from changes to estimated Earn-out accruals, approximately $6 million of other miscellaneous income, offset, in part, by approximately $4 million of expense, net, from the changes in the fair value of additional contingent payments to former owners of an acquired business. For the year ended December 31, 2024, other expense, net, included approximately $5 million of expense, net, from changes to estimated Earn-out accruals, approximately $5 million of expense, net, from the changes in the fair value of additional contingent payments to former owners of an acquired business and approximately $6 million of asset impairments related to certain fixed assets, offset, in part, by approximately $3 million of other miscellaneous income, net, including from legal and other settlements.
Provision for income taxes. For the year ended December 31, 2025, our effective tax rate was an expense of 18.1% as compared with an expense of 20.5% for the same period in 2024. Our effective tax rate for the year ended December 31, 2025 included income tax benefits primarily from the reversal of uncertain tax position liabilities, the release of valuation allowances on certain deferred tax assets, benefits from certain tax credits; offset, in part, by the effects of a higher state income tax rate, whereas for the year ended December 31, 2024, our effective tax rate included the effects of a lower state income tax rate and tax credits.
Net income attributable to non-controlling interests. Net income attributable to non-controlling interests was $23 million for the year ended December 31, 2025, as compared with $37 million for the same period in 2024. The decrease was primarily attributable to the decrease in activity of certain entities within the Pipeline Infrastructure and Communications segments with minority interest holders.
Analysis of Revenue and EBITDA by Segment
We review our operating results by reportable segment. See Note 14 - Segments and Related Information in the notes to the audited consolidated financial statements, which is incorporated by reference. Our reportable segments are: (1) Communications; (2) Clean Energy and Infrastructure; (3) Power Delivery; (4) Pipeline Infrastructure and (5) Other. Management’s review of segment results includes analyses of trends in revenue, EBITDA and EBITDA margin. EBITDA for segment reporting purposes is calculated consistently with our consolidated EBITDA calculation. EBITDA margin is calculated by dividing EBITDA by revenue for the same period. See the discussion of our non-U.S. GAAP financial measures, including certain adjusted non-U.S. GAAP measures, as described below, following the comparison of results discussion.

(a) Recast to reflect 2025 segment changes. See Note 14 - Segments and Related Information in the notes to the consolidated audited financial statements, which is incorporated by reference, for additional information.
Communications Segment Results
Revenue. The increase in revenue was driven primarily by higher levels of wireless and wireline project activity due, in part, to increased customer demand, offset, in part, by a decrease in our install-to-the-home project activity due, in part, to changes in consumer behavior.
EBITDA. As a percentage of revenue, EBITDA increased by approximately 50 basis points, or $18 million, due to improved project efficiencies, including from our wireless and wireline businesses. Higher levels of revenue resulted in an increase in EBITDA of approximately $71 million.
43
Clean Energy and Infrastructure Segment Results
Revenue. The increase in revenue was due primarily to higher levels of project activity, primarily in our renewable projects.
EBITDA. As a percentage of revenue, EBITDA increased by approximately 110 basis points, or $53 million, due to a combination of project mix, the positive effects of certain renewable project close-outs, and improved productivity and efficiencies, primarily from certain renewable and infrastructure project work. Higher levels of revenue resulted in an increase in EBITDA of approximately $38 million.
Power Delivery Segment Results
Revenue. The increase in revenue was due primarily to higher levels of project activity in transmission and distribution-related project work, as well as higher levels of certain infrastructure-related project work. These increases were offset, in part, by a decrease in substation-related project activity, as well as a decrease in demand for emergency restoration services.
EBITDA. As a percentage of revenue, EBITDA decreased by approximately 20 basis points, or $9 million, primarily due to reduced efficiencies at certain of our project sites and a reduction in emergency restoration services. Higher levels of revenue contributed an increase in EBITDA of approximately $47 million.
Pipeline Infrastructure Segment Results
Revenue. Revenue was generally flat as compared with 2024, due primarily to an increase in other infrastructure-related work, offset by lower levels of midstream pipeline project activity.
EBITDA. As a percentage of revenue, EBITDA decreased by approximately 340 basis points, or $72 million, due primarily to reduced efficiencies, including from a reduction in revenue on midstream pipeline projects, the effects of project mix, and the effects of certain overhead costs incurred to maintain operating capacity in support of expected future project work.
Other Segment Results
EBITDA. EBITDA from Other businesses relates primarily to equity in earnings from our investments in the Waha JVs, offset, in part, by losses from other businesses and investments.
Corporate Results
EBITDA. For the year ended December 31, 2025, Corporate EBITDA included $3 million of income, net, from changes to estimated Earn-out accruals and $4 million of expense, net, from the changes in the fair value of additional contingent payments to former owners of an acquired business. For the year ended December 31, 2024, Corporate EBITDA included approximately $11 million of a loss on debt extinguishment, $5 million of expense, net, from changes to estimated Earn-out accruals, and $5 million of expense from the changes in the fair value of additional contingent payments to former owners of an acquired business. Corporate expenses for the year ended December 31, 2025 not related to the above-described items increased by approximately $7 million as compared with the same period in 2024, due primarily to increases in compensation expense and other administrative expenses, including professional fees, offset, in part, by the effects of timing of ordinary course legal and other settlement matters.
Comparison of Years Ended December 31, 2024 and 2023
Refer to Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Comparison of Years Ended December 31, 2024 and 2023” of the Company’s 2024 Annual Report on Form 10-K (the “2024 Form 10-K”) for a comparison of results for the years ended December 31, 2024 and 2023, which discussion is incorporated herein by reference.
Foreign Operations
Our foreign operations are primarily in Canada. See Note 14 - Segments and Related Information in the notes to the audited consolidated financial statements, which is incorporated by reference.
Non-U.S. GAAP Financial Measures
As appropriate, we supplement our reported U.S. GAAP financial information with certain non-U.S. GAAP financial measures, including earnings before interest, income taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA (“Adjusted EBITDA”), adjusted net income (“Adjusted Net Income”), adjusted net income attributable to MasTec, Inc. (“Adjusted Net Income Attributable to MasTec, Inc.”) and adjusted diluted earnings per share (“Adjusted Diluted Earnings Per Share”). These “adjusted” non-U.S. GAAP measures exclude, as applicable to the respective periods, non-cash stock-based compensation expense; loss on extinguishment of debt; changes in fair value of acquisition-related contingent items; acquisition and integration costs related to certain acquisition activity, as more fully described below; fair value gains or losses, net, on an investment; and, for Adjusted Net Income, Adjusted Net Income Attributable to MasTec, Inc. and Adjusted Diluted Earnings Per Share, amortization of intangible assets, the effects of statutory and other tax rate changes, and the tax effects of the adjusted items. These definitions of EBITDA and Adjusted EBITDA are not the same as in our Credit Facility or in the indenture governing our senior notes; therefore, EBITDA and Adjusted EBITDA as presented in this discussion should not be used for purposes of determining our compliance with the covenants contained in our debt instruments.
We use EBITDA and Adjusted EBITDA, as well as Adjusted Net Income, Adjusted Net Income Attributable to MasTec, Inc. and Adjusted Diluted Earnings Per Share, to evaluate our performance, both internally and as compared with our peers, because these measures exclude certain items that may not be indicative of our core, or underlying, operating results, as well as items that can vary widely across different industries or among companies within the same industry. We believe that these adjusted measures provide a baseline for analyzing trends in our underlying business. Non-cash stock-based compensation expense can be subject to volatility from changes in the market price per share of our common stock
44
or variations in the value and number of shares granted, and amortization of intangible assets is subject to acquisition activity, which varies from period to period.
Our computation of non-U.S. GAAP financial measures excludes the effects of changes in fair value of acquisition-related contingent items due to their non-operational nature and inherent volatility, as activity varies from period to period. Acquisition-related contingent items consist of (i) changes in fair value of acquisition-related contingent consideration, which is composed of earn-outs, that are contingent upon the achievement of reaching certain post-acquisition levels of earnings and (ii) changes in fair value of additional payments in connection with the 2021 acquisition of Henkels & McCoy Holdings, Inc., formerly known as Henkels & McCoy Group, Inc. (“HMG”), based on the fluctuation of our share price and are contingent upon the post-acquisition collections of certain receivables. We believe that this presentation is common practice within our industry and improves comparability of our results with those of our peers. See Note 3 - Acquisitions, Goodwill and Other Intangible Assets, Net and Note 4 - Fair Value of Financial Instruments in the notes to the audited consolidated financial statements, which is incorporated by reference, for additional details regarding these acquisition-related contingent items.
In 2021, we initiated a significant transformation of our end-market business operations to focus on the nation’s transition to low-carbon energy sources and position the Company for expected future opportunities. This transformation included significant acquisition activity to expand our scale and capacity in renewable energy, power delivery, heavy civil and telecommunications services, and resulted in significant acquisition and integration costs. Due to the extent of the acquisition costs related to this acquisition activity and the extent of the efforts that were required to integrate these acquisitions, we have excluded acquisition and integration costs related to this acquisition activity in our computation of non-U.S. GAAP financial measures. These acquisition and integration activities were completed in the fourth quarter of 2023.
Our adjusted results also exclude fair value gains or losses, net, for our investment in American Virtual Cloud Technologies, Inc. (“AVCT”). We believe that fair value gains or losses for our investment in AVCT, a company in which we had no active involvement and for which fair value activity varied from period to period based on fluctuations in the market price of the investment, are not indicative of our core operations, and that this presentation improves comparability of our results with those of our peers. AVCT filed for bankruptcy in the first quarter of 2023, and our investment was fully written off.
We exclude intangible asset amortization from our non-U.S. GAAP financial measures due to its non-operational nature and inherent volatility, as acquisition activity varies from period to period. We believe that this presentation is common practice within our industry and improves comparability of our results with those of our peers. Note that while intangible asset amortization related to the assets of acquired entities is excluded from our non-U.S. GAAP financial measures, the revenue and all other expenses of the acquired entities are included within our non-U.S. GAAP financial measures, unless otherwise stated. We have also excluded the effects of statutory and other tax rate changes from Adjusted Net Income and Adjusted Diluted Earnings Per Share given their inherent volatility due to uncertainty with regard to our future geographic footprint and the associated tax rates, which may vary significantly from period to period, and, for statutory tax rate changes, due to their non-operational nature.
We believe that these non-U.S. GAAP financial measures provide meaningful information and help investors understand our financial results and assess our prospects for future performance. Because non-U.S. GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-U.S. GAAP financial measures having the same or similar names. Each company’s definitions of these adjusted measures may vary as they are not standardized and should be used together with the provided reconciliations. These financial measures should not be considered in isolation from, as substitutes for, or alternative measures of, reported net income (loss) or diluted earnings (loss) per share, and should be viewed in conjunction with the most comparable U.S. GAAP financial measures and the provided reconciliations thereto. We believe these non-U.S. GAAP financial measures, when viewed together with our U.S. GAAP results and related reconciliations, provide a more complete understanding of our business. We strongly encourage investors to review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

Financial Condition, Liquidity and Capital Resources
Our primary sources of liquidity are cash flows from operations, availability under our Credit Facility and our cash balances. Our primary liquidity needs are for working capital, capital expenditures, insurance and performance collateral in the form of cash and letters of credit, debt service, income taxes, earn-out obligations and equity and other investment funding requirements. We also evaluate opportunities for strategic acquisitions, investments and other arrangements from time to time, and we may consider opportunities to refinance, extend the terms of our existing indebtedness, retire outstanding debt, borrow additional funds, which may include borrowings under our Credit Facility or debt issuances, or repurchase additional shares of our outstanding common stock under share repurchase authorizations, any of which may require our use of cash. See Note 8 - Debt in the notes to the audited consolidated financial statements, which is incorporated by reference, for details of our recent debt transactions, including the amendment and restatement of our senior credit facility and the repayment of the outstanding loans under the existing credit agreement, our new term loan facility, and the repayment of our five-year term loan.
Capital Expenditures. For the year ended December 31, 2025, we spent approximately $260 million on capital expenditures, or $204 million, net of asset disposals, and incurred approximately $229 million of equipment purchases under finance leases and other financing arrangements. We estimate that we will spend approximately $270 million on capital expenditures, or approximately $200 million, net of asset disposals, in 2026, and we expect to incur approximately $230 million to $255 million of equipment purchases under finance leases and other financing arrangements. Actual capital expenditures may increase or decrease in the future depending upon business activity levels, as well as ongoing assessments of equipment lease and other financing arrangements versus purchase decisions based on management’s evaluation of short and long-term equipment requirements.
Acquisitions and Earn-Out Liabilities. We typically utilize cash for business acquisitions and other strategic arrangements, and for the year ended December 31, 2025, we used $71 million of cash for this purpose. In addition, in most of our acquisitions, we have agreed to make future payments to the sellers that are contingent upon the future earnings performance of the acquired businesses, which we also refer to as “Earn-out” payments. From time to time, our acquisitions may contain certain additional payments if specified conditions are met. Earn-out payments may be paid in cash or, under specific circumstances, MasTec common stock, or a combination thereof, generally at our option. The estimated total value of future Earn-out liabilities as of December 31, 2025 was approximately $73 million. Of this amount, approximately $21 million represents the liability for earned amounts. The remainder is management’s estimate of Earn-out liabilities that are contingent upon future performance. For the years ended December 31, 2025, 2024 and 2023, we made $49 million, $26 million and $39 million, respectively, of payments related to our Earn-out liabilities. In the first quarter of 2026, we completed one acquisition for an aggregate purchase price of $262 million in cash. See “Business” discussion above for details of our recent acquisitions.
Our acquisition of HMG in 2021 provided for certain additional payments to be made to the sellers if certain acquired receivables are collected, which we refer to as the “Additional Payments.” As of December 31, 2025, the estimated fair value of remaining Additional Payments was approximately $18 million, which for the year ended December 31, 2025, includes the effect of fair value adjustments related to the contingent shares totaling losses of approximately $4.1 million. The number of shares that would be paid in connection with the remaining Additional Payments as of December 31, 2025 is approximately 50,000 shares.
Income Taxes. Tax payments, net of tax refunds, totaled $44 million for both the years ended December 31, 2025 and 2024 and $10 million for the year ended December 31, 2023. Our tax payments vary with changes in taxable income and earnings based on estimates of full year taxable income activity and estimated tax rates.
47
Working Capital. We need working capital to support seasonal and other variations in our business, primarily related to the effects of weather conditions on outdoor construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated spending to support customer demand. Working capital needs are 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. Conversely, working capital needs are typically converted to cash during the winter months. These seasonal trends, however, can be offset by changes in the timing of projects, which can be affected by project delays or accelerations and/or other factors that may affect customer spending.
Working capital requirements also tend to increase when we commence multiple projects or particularly large projects because labor, including subcontractor costs, and certain other costs, including inventory and materials requirements, typically become payable before the receivables resulting from work performed are collected. The timing of billings and project close-outs can also contribute to changes in billed and unbilled revenue. As of December 31, 2025, we expect that substantially all of our unbilled receivables will be billed to customers in the normal course of business within the next twelve months. Total accounts receivable, which consists of contract billings, unbilled receivables and retainage, net of allowance, totaled approximately $3.5 billion as of December 31, 2025 as compared with $2.9 billion as of December 31, 2024, due primarily to higher levels of revenue, as well as the timing of project billings and collections. See below for discussion of our days sales outstanding, net of contract liabilities, which we refer to as days sales outstanding, or “DSO.”
Our payment billing terms are generally net 30 days, and some of our contracts allow our customers to retain a portion of the contract amount, generally from 5% to 10% of billings, until the job is completed, which amounts are referred to as “retainage.” As part of our ongoing working capital management practices, we evaluate opportunities to improve our working capital cycle time through contractual provisions and certain financing arrangements. For certain customers, we maintain inventory to meet the materials requirements of the contracts. Occasionally, certain of our customers pay us in advance for a portion of the materials we purchase for their projects or allow us to pre-bill them for the mobilization of assets and/or crew to project sites and/or for materials purchases up to specified amounts. Vendor terms generally range from 30 to 60 days. Our agreements with subcontractors often contain a “pay-if-paid” provision, whereby our payments are contractually due to subcontractors only after we are paid by our customers.
Summary of Financial Condition, Liquidity and Capital Resources
Including our current assessment of general economic and market conditions on our results of operations and capital resource requirements, we anticipate that funds generated from operations, borrowings under our credit facilities and our cash balances will be sufficient to meet our working capital requirements, anticipated capital expenditures, debt service obligations, insurance and performance collateral requirements, letter of credit needs, earn-out obligations, required income tax payments, as well as potential acquisition, strategic arrangement and investment funding requirements and/or share repurchase activity and other liquidity needs for the next twelve months and the foreseeable future.
Sources and Uses of Cash
As of December 31, 2025, we had approximately $1,058 million in working capital, defined as current assets less current liabilities, as compared with $653 million as of December 31, 2024, an increase of approximately $405 million. Cash and cash equivalents totaled approximately $396 million and $400 million as of December 31, 2025 and 2024, respectively, for a decrease of $4 million. See discussion below for further detail regarding our cash flows and related activity.
Sources and uses of cash are summarized below (in millions):
| Year Ended December 31, | |||||||||||||||||
| 2025 | 2024 | 2023 | |||||||||||||||
| Net cash provided by operating activities | $ | 545.7 | $ | 1,121.6 | $ | 687.3 | |||||||||||
| Net cash used in investing activities | $ | (267.2) | $ | (157.5) | $ | (178.1) | |||||||||||
| Net cash used in financing activities | $ | (283.4) | $ | (1,090.2) | $ | (351.0) | |||||||||||
Operating Activities. Cash flow from operations is primarily influenced by changes in the timing of demand for our services and operating margins, but can also be affected by working capital needs associated with the various types of services we provide. Working capital is affected by changes in total accounts receivable, net, prepaid expenses and other current assets, accounts payable and payroll tax payments, accrued expenses and contract liabilities, all of which tend to be related. These working capital items are affected by changes in revenue resulting from the timing and volume of work performed, variability in the timing of customer billings and collections of receivables, as well as settlement of payables and other obligations. Net cash provided by operating activities for the year ended December 31, 2025 was $546 million, as compared with $1,122 million in 2024, for a decrease in net cash provided by operating activities of approximately $576 million. The decrease was due primarily to changes in working capital compared with the prior period, including from the negative effect of timing-related changes in accounts receivable, net, primarily driven by higher levels of revenue and an increase in DSO, and contract liabilities, offset, in part, by the positive effect of timing-related changes in accounts payable and accrued expenses, and an increase in net income as compared with the prior period.
DSO is calculated as total accounts receivable, net of allowance, less contract liabilities, divided by average daily revenue for the most recently completed quarter as of the balance sheet date. A decrease in DSO has a favorable impact on cash flow from operating activities, while an increase in DSO has a negative impact on cash flow from operating activities. Our DSO was 65 as of December 31, 2025, as compared with DSO of 60 as of December 31, 2024. Our DSOs can fluctuate from period to period due to timing of billings, billing terms, collections and settlements, timing of project close-outs and retainage collections, changes in project and customer mix and to a lesser extent the effect of working capital initiatives, including certain accounts receivable financing arrangements. The increase in DSO as of December 31, 2025 as compared with December 31, 2024 was due to timing of ordinary course billing and collection activities. Other than certain ordinary course matters subject to litigation, we do not anticipate material collection issues related to our outstanding accounts receivable balances, nor do we believe that we have
48
material amounts due from customers experiencing financial difficulties. Based on current information, we expect to collect substantially all of our outstanding accounts receivable balances within the next twelve months.
Investing Activities. Net cash used in investing activities was $267 million as compared to $157 million for the year ended December 31, 2025 and 2024, respectively, for an increase of $110 million. Capital expenditures totaled $260 million, or $204 million, net of asset disposals, for the year ended December 31, 2025, as compared with $149 million, or $83 million, net of asset disposals, for the same period in 2024, for an increase in cash used in investing activities of approximately $121 million, primarily to support operational growth and the replacement of older machinery and equipment.
Financing Activities. Net cash used in financing activities for the year ended December 31, 2025 was $283 million, as compared with net cash used in financing activities of $1,090 million in 2024, for a decrease in cash used in financing activities of approximately $807 million. For the year ended December 31, 2025, we had $56 million of borrowings, net of repayments, under our credit facility and term loans, as compared with $1,154 million of repayments, net of borrowings, for the same period in 2024, for a decrease in cash used in financing activities of $1,209 million. The decrease in cash used in financing activities from the above was offset, in part, by an increase in net proceeds of Senior Notes for the year ended December 31, 2024 of $326 million, consisting of $550 million in proceeds from our 5.900% Senior Notes and $224 million of repayments made on our 6.625% Senior Notes. Share repurchases totaled approximately $77 million for the year ended December 31, 2025, whereas there were no share repurchases for the same period in 2024. Additionally, payments of acquisition-related contingent consideration included within financing activities increased by $18 million. Total payments of acquisition-related contingent consideration, including payments in excess of acquisition-date liabilities, which are classified within operating activities, totaled $49 million for the year ended December 31, 2025 as compared with $26 million for the same period in 2024.
Senior Credit Facility
On June 26, 2025, we amended and restated our five-year, senior unsecured credit facility (the “Credit Facility”), which matures on June 26, 2030 and is composed of $1.9 billion of revolving commitments. As of December 31, 2025, aggregate outstanding revolving borrowings totaled approximately $118 million and availability for revolving loans totaled $1,725 million. Borrowings under our Credit Facility are used for working capital requirements, capital expenditures and other corporate purposes, including acquisitions, equity investments or other strategic arrangements, and/or the repurchase or prepayment of indebtedness, among other corporate borrowing requirements, including potential share repurchases.
We are dependent upon borrowings and letters of credit under our Credit Facility to fund our operations. Should we be unable to comply with the terms and conditions of our Credit Facility, we would be required to obtain modifications to the Credit Facility or obtain an alternative source of financing to continue to operate, neither of which may be available to us on commercially reasonable terms, or at all. The Credit Facility is subject to certain provisions and covenants, as more fully described in Note 8 - Debt in the notes to the audited consolidated financial statements, which is incorporated by reference.
Senior Notes
4.500% Senior Notes. We have $600 million aggregate principal amount of 4.500% senior unsecured notes due August 15, 2028 (the “4.500% Senior Notes”).
5.900% Senior Notes. We have $550 million aggregate principal amount of 5.900% senior unsecured notes due June 15, 2029 (the “5.900% Senior Notes”).
6.625% Senior Notes. We have $75 million aggregate principal amount of 6.625% senior unsecured notes due August 15, 2029 (the “6.625% Senior Notes”).
The Senior Notes described above are subject to certain provisions and covenants, as more fully described in Note 8 - Debt in the notes to the audited consolidated financial statements, which is incorporated by reference.
2025 Term Loan Facility
On June 26, 2025, we entered into a new $600 million senior unsecured term loan agreement (the “2025 Term Loan Facility”) which matures on June 26, 2028 and the loans thereunder are not subject to amortization. In the second quarter of 2025, we used the proceeds from the 2025 Term Loan Facility, together with available cash, to repay the $328.1 million term loan under our Existing Credit Agreement and the remaining $277.5 million of our Five-Year Term Loan that would otherwise have matured on October 7, 2027.

Contractual Payment Obligations
The following table sets forth our contractual payment obligations as of December 31, 2025 during the periods indicated below (in millions):

(a) Under certain acquisition agreements, we have agreed to pay the sellers earn-outs and other amounts based on the performance of the businesses acquired. Certain of these payments may be made either in cash or in MasTec common stock, or a combination thereof, at our option. Due to the contingent nature of these payments, we have only included obligations that we expect will be paid in cash and have been earned as of December 31, 2025.
(b) Represents expected future interest payments on debt, finance lease and other obligations outstanding as of December 31, 2025, and does not include potential letter of credit or commitment fees associated with our senior unsecured credit facility. With respect to our variable rate debt, consisting of our senior unsecured credit facility and 2025 Term Loan Facility, the expected future interest assumes the principal amount outstanding and interest rates in effect as of December 31, 2025 remain the same. With the exception of our senior unsecured credit facility and 2025 Term Loan Facility, all of our debt instruments are fixed rate interest obligations.
Off-Balance Sheet Arrangements
As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases with durations of less than twelve months, letter of credit obligations, surety and performance and payment bonds entered into in the normal course of business, self-insurance liabilities, liabilities associated with multiemployer pension plans, liabilities associated with potential funding obligations and indemnification and/or guarantee arrangements relating to our equity and other investment arrangements, including our variable interest entities. These off-balance sheet arrangements have not had, and are not reasonably likely to have, a material impact on our financial condition, revenue or expenses, results of operations, liquidity, cash requirements or capital resources in the next twelve months or in the foreseeable future. Refer to Note 4 - Fair Value of Financial Instruments, Note 15 - Commitments and Contingencies and Note 16 - Related Party Transactions in the notes to the audited consolidated financial statements, which are incorporated by reference, for additional information related to our off-balance sheet arrangements.
Impact of Inflation
The primary inflationary factors directly affecting our operations are labor, fuel and material costs. The labor market remains at low levels of unemployment, creating pressure on the supply of skilled labor. In times of low unemployment and/or high inflation, our labor costs may increase due to shortages in the supply of skilled labor and increases in compensation rates generally. Changes to immigration policy may also affect the availability of labor. Although most project materials are provided by our customers, increases in the cost of materials could negatively affect the economic viability of our customers’ projects, and accordingly, demand for our services. Material and commodity prices are subject to volatility due to events outside of our control, such as tariff and trade actions, fluctuations in global supply and demand, climate-related effects, and geopolitical events, which events have caused and could create heightened global market volatility in the future. Inflation rates in the United States increased significantly over the past several years and, while recent inflationary pressure has somewhat abated, the high-cost environment remains intact and we expect it to continue in 2026 due, in part, to trade actions described above under “General Economic, Market and Regulatory Conditions.”
Elevated levels of labor, fuel and material costs have in the past and could in the future negatively affect our project margins to the extent that we are unable to pass such cost increases along to our customers. In addition, there is uncertainty to what effect, if any, trade tariffs will have on inflation in future periods. Such market and economic volatility and/or uncertainty can also affect our customers’ investment decisions and subject us to project cancellations, deferrals or unexpected changes in the timing, type and scope of project work. Market prices for goods can also be affected by supply chain disruptions, which in the past have negatively affected our operations, as discussed in Item 1. “Business,” under “Suppliers, Materials and Working Capital.”
50
While inflationary factors have not had a material impact on our business, results of operations and/or financial condition, we closely monitor such factors, and any potential effects they may have on our business operations. While the impact of these factors cannot be fully eliminated, we take proactive steps to mitigate their effects; however, inflationary pressures could adversely affect our business operations in the future.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
Our interest expense is affected by the prevailing interest rate environment. While the cost of our variable-rate debt fluctuates with changes in market interest rates, interest on our fixed-rate debt is unaffected by such changes. We manage interest rate risk by maintaining a mix of fixed and variable rate debt obligations. As of December 31, 2025, our variable interest rate debt was primarily related to our Credit Facility and our 2025 Term Loan Facility. Outstanding revolving loans under our Credit Facility bear interest, at our option, at a rate equal to either (a) Term Secured Overnight Financing Rate (“SOFR”), TIIE, or Term CORRA, as defined in the Credit Facility, plus a margin of 1.125% to 1.625%, or (b) a Base Rate, as defined in the Credit Facility, plus a margin of 0.125% to 0.625%. Outstanding loans under our 2025 Term Loan Facility bear interest, at our option, at a rate equal to either (a) Term SOFR, as defined in the 2025 Term Loan Facility, plus a margin of 1.00% to 1.50%, or (b) a Base Rate, as defined in the 2025 Term Loan Facility, plus a margin of up to 0.50%.
As of December 31, 2025, we had approximately $118 million aggregate principal amount of outstanding revolving loans under our Credit Facility with a weighted average interest rate of 4.56% and $600 million outstanding under our 2025 Term Loan Facility with a weighted average interest rate of 4.85%. An additional 100 basis point increase in the applicable interest rates under our Credit Facility and 2025 Term Loan Facility would have increased our interest expense by approximately $9 million for the year ended December 31, 2025.
As of December 31, 2025, our fixed interest rate debt primarily included $600 million aggregate principal amount of 4.500% Senior Notes, $550 million aggregate principal amount of 5.900% Senior Notes, $74.9 million aggregate principal amount of 6.625% Senior Notes and $343.6 million of finance lease obligations, which accrued interest at a weighted average interest rate of approximately 4.9%. None of this debt subjects us to financial statement risk associated with changes in interest rates, but we may be subject to changes in interest rates if and when we refinance this debt at maturity or otherwise.
Foreign Currency Risk
Certain of our consolidated revenue and operating expenses are in foreign currencies. Our foreign operations are primarily in Canada. Revenue generated from foreign operations represented approximately 1% of our total revenue for the year ended December 31, 2025. Revenue and expense related to our foreign operations are, for the most part, denominated in the functional currency of the foreign operation, which minimizes the impact that fluctuations in exchange rates would have on net income or loss. We are, however, subject to fluctuations in foreign currency exchange rates when transactions are denominated in currencies other than the functional currencies and for our foreign operations with a functional currency other than the local currency. Such activity was not material to our operations in 2025. Translation gains or losses, which are recorded in other comprehensive income or loss, result from translation of the assets and liabilities of our foreign subsidiaries into U.S. dollars. For the year ended December 31, 2025, foreign currency translation gains, net, totaled approximately $4.0 million and related primarily to our activities in Canada and Mexico.
Our exposure to fluctuations in foreign currency exchange rates could increase in the future if we continue to expand our operations outside of the United States. We seek to manage foreign currency exposure by minimizing our consolidated net asset and liability positions in currencies other than the functional currency, which exposure was not significant to our consolidated financial position as of December 31, 2025. We may enter into foreign currency derivative contracts in the future to manage such exposure.
Other Market Risk
As discussed in Note 4 - Fair Value of Financial Instruments in the notes to the audited consolidated financial statements, which is incorporated by reference, we have certain investments that may be subject to market risk and could be subject to volatility based on market conditions.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of MasTec, Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of MasTec, Inc. and its subsidiaries (the “Company”) as of December 31, 2025 and 2024, and the related consolidated statements of operations, of comprehensive income (loss), of equity and of cash flows for the years then ended, including the related notes and schedule of valuation and qualifying accounts for the years ended December 31, 2025 and 2024 appearing after Item 16 (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
As described in Management’s Report on Internal Control Over Financial Reporting, management has excluded four entities (related to a July and a November acquisition in the Communications segment, an August acquisition in the Pipeline Infrastructure segment, and a December acquisition in the Clean Energy and Infrastructure segment) from its assessment of internal control over financial reporting as of December 31, 2025 because they were acquired by the Company in purchase business combinations during 2025. We have also excluded the four entities from our audit of internal control over financial reporting. The four entities’ total assets and total revenues excluded from management’s assessment and our audit of internal control over financial reporting collectively represent approximately 2% and less than 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2025.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
53
Revenue Recognition – Determination of Estimated Costs to Complete Certain Contracts Recognized Over Time
The Company recognized revenue of $14.3 billion for the year ended December 31, 2025, of which a majority relates to revenue recognized from contracts for specific projects requiring the construction and installation of an entire infrastructure system, or specified units within an infrastructure system. As described in Note 1 to the consolidated financial statements, revenue related to these contracts is primarily recognized over time using the cost-to-cost measure of progress, which is an input method. Contract costs include all direct materials, equipment, labor and subcontracted costs related to contract performance. The cost estimation processes used for recognizing revenue over time under the cost-to-cost method require management to make significant assumptions and judgments, based primarily on the professional knowledge and experience of the Company’s project managers, operational and financial professionals. Changes in job performance and job conditions are factors that influence estimates of the total costs to complete those contracts. Changes in these factors that result in revisions to the amount of revenue recognized for a given project are recognized in the period in which the revisions are determined.
The principal considerations for our determination that performing procedures relating to revenue recognition, specifically the determination of estimated costs to complete certain contracts recognized over time, is a critical audit matter are (i) the significant judgment by management in determining the estimated contract costs to complete; and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to management’s estimate of costs to complete.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process, including controls related to the determination of estimated costs to complete certain contracts recognized over time. These procedures also included, among others, (i) for a sample of certain open contracts, testing management’s process for determining the estimated contract costs to complete; (ii) testing the completeness and accuracy of underlying data used by management related to actual costs to date; and (iii) for a sample of certain open contracts, evaluating the reasonableness of certain significant judgments and assumptions related to estimated contract costs to complete considered by management specific to each contract tested. Evaluating the reasonableness of certain significant judgments and assumptions related to estimated contract costs to complete involved considering (i) the terms of the contracts and other documents related to job performance that support those estimates; (ii) actual costs to date to assess the reasonableness of the estimate of the remaining costs to complete; (iii) management’s ability to reasonably estimate costs to complete by comparing total estimated contract costs with prior period estimates, including evaluating the timely identification of circumstances that may warrant a modification to the estimated contract costs to complete; and (iv) evaluating management’s cost-to-cost method and the consistency of management’s method over the lives of contracts.

Opinion on the Financial Statements
We have audited the consolidated statement of operations, members’ equity (deficit), and cash flows of IEA Energy Services, LLC and its consolidated subsidiaries (“IEA LLC”), for the year ended December 31, 2023, and the related notes (collectively referred to as the "financial statements" and not presented herein).
In our opinion, the financial statements referred to above present fairly, in all material respects, the results of IEA LLC’s operations and its cash flows for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
IEA LLC’s management is responsible for these financial statements. Our responsibility is to express an opinion on these financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to IEA LLC in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audit of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.
Other Matter
As discussed in Note 10 to the IEA LLC financial statements, IEA LLC engages in significant transactions with affiliates such as MasTec, Inc. and Infrastructure and Energy Alternatives, Inc. Portions of certain income and expenses represent allocations made from affiliates for items applicable to IEA LLC as a whole. Therefore, the financial statements of IEA LLC have been prepared from the separate records maintained by IEA LLC and its parent and may not be indicative of the conditions that would have existed or the results of operations if IEA LLC had been operated as an unaffiliated company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1 – Business, Basis of Presentation and Significant Accounting Policies
Nature of the Business
MasTec, Inc. (collectively with its subsidiaries, “MasTec,” or the “Company”) is a leading North American infrastructure engineering and construction company focused primarily on engineering, building, installation, maintenance and upgrade of communications, energy and utility and other infrastructure, such as: wireless, wireline/fiber; power delivery infrastructure, including transmission, distribution, grid hardening and modernization, environmental planning and compliance; power generation infrastructure, primarily from clean energy and renewable sources; pipeline infrastructure, including for natural gas, water and carbon capture sequestration pipelines and pipeline integrity services; heavy civil and industrial infrastructure, including roads, bridges and rail; and environmental remediation services. MasTec’s customers are primarily in these industries. MasTec reports its results under five reportable segments: (1) Communications; (2) Clean Energy and Infrastructure; (3) Power Delivery; (4) Pipeline Infrastructure and (5) Other.
In the first quarter of 2025, the Company made changes to its Communications and Power Delivery segment structures to more closely align with the segments’ end markets and to better correspond with the operational management reporting structures of both segments. These changes included moving a component with utility operations previously reported in the Communications segment to the Power Delivery segment. These changes did not impact the Company’s consolidated financial statements, but did impact its reportable segments, including historical financial information. See Note 14 - Segments and Related Information for additional information pertaining to the Company’s reportable segments. The segments are reported on a comparable basis for all periods presented.
Principles of Consolidation
The accompanying consolidated financial statements include MasTec, Inc. and its subsidiaries and include the accounts of all majority owned subsidiaries over which the Company exercises control and, when applicable, entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Other parties’ interests in entities that MasTec consolidates are reported as non-controlling interests within equity. Net income or loss attributable to non-controlling interests is reported as “Net income attributable to non-controlling interests” in the consolidated statements of operations. Investments in entities for which the Company does not have a controlling financial interest, but over which it has the ability to exert significant influence, are accounted for under the equity method of accounting. For equity investees in which the Company has an undivided interest in the assets, liabilities and profits or losses of an unincorporated entity, but does not exercise control over the entity, the Company consolidates its proportional interest in the accounts of the entity. When appropriate, prior year amounts are reclassified to conform with the current period presentation.
Translation of Foreign Currencies
The assets and liabilities of foreign subsidiaries with a functional currency other than the U.S. dollar are translated into U.S. dollars at period-end exchange rates and revenue and expenses are translated at average rates of exchange during the applicable period, with resulting translation gains or losses included within other comprehensive income or loss. Substantially all of the Company’s foreign operations use their local currency as their functional currency. For foreign operations for which the local currency is not the functional currency, the operation’s non-monetary assets are remeasured into U.S. dollars at historical exchange rates. All other accounts are remeasured at current exchange rates. Gains or losses from remeasurement are included in other income or expense, net. Currency gains or losses resulting from transactions executed in currencies other than the functional currency are included in other income or expense, net.
In these consolidated financial statements, “$” means U.S. dollars unless otherwise noted.
Management Estimates
The preparation of consolidated financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates are based on historical experience and various other assumptions that management believes to be reasonable under the circumstances, including the potential future effects of macroeconomic trends and events, such as inflation and interest rate levels; uncertainty from potential market volatility; other market, industry and regulatory factors, including uncertainty related to the implementation and pace of governmental programs and initiatives and project permitting issues, and other regulatory matters or uncertainty; evolving trade and immigration policies; supply chain disruptions; climate-related matters; global events, such as military conflicts; and public health matters. These estimates form the basis for making judgments about the Company’s operating results and the carrying values of assets and liabilities that are not readily apparent from other sources. While management believes that such estimates are reasonable when considered in conjunction with the Company’s consolidated financial position and results of operations taken as a whole, actual results could differ materially from these estimates if conditions change or if certain key assumptions used in making these estimates ultimately prove to be inaccurate.
Key estimates include: the recognition of revenue and project profit or loss, which the Company defines 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 goodwill and intangible assets, long-lived and other assets, equity investments, financial instruments, acquisition-related liabilities, including contingent consideration, other liabilities and debt obligations; useful lives of long-lived assets; self-insurance liabilities; allowances for credit losses; certain other accruals and allowances; income taxes; and the estimated effects of litigation and other contingencies.
62
Significant Accounting Policies
The following is a summary of significant accounting policies followed in the preparation of the accompanying consolidated financial statements.
Revenue Recognition
The Company recognizes revenue from contracts with customers when, or as, control of promised services and goods is transferred to customers. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the services and goods transferred. The Company primarily recognizes revenue over time utilizing the cost-to-cost measure of progress, which best depicts the continuous transfer of control of goods or services to the customer, and correspondingly, when performance obligations are satisfied for the related contracts. For the years ended December 31, 2025, 2024 and 2023, consolidated revenue totaled approximately $14.3 billion, $12.3 billion and $12.0 billion, respectively.
Contracts. The Company derives revenue primarily from construction projects performed under: (i) master service and other service agreements, which generally 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 may be subject to one or multiple pricing models, including fixed price, unit price, time and materials, or cost plus a markup. Revenue derived from projects performed under master service and other service agreements totaled 44 %, 41 % and 40 % of consolidated revenue for the years ended December 31, 2025, 2024 and 2023, respectively.
Revenue from contracts for specific projects, as well as for certain projects pursuant to master and other service agreements, is typically recognized over time using the cost-to-cost measure of progress, which is an input method. Such contracts provide that the customer accept completion of progress to date and compensate the Company for services rendered.
For certain master service and other service agreements, revenue is recognized at a point in time, primarily for install-to-the-home and certain other wireless services in the Company’s Communications segment. Point in time revenue is recognized when the work order has been fulfilled, which, for the majority of the Company’s point in time revenue, is the same day it is initiated. Point in time revenue accounted for approximately 1 % of consolidated revenue for the year ended December 31, 2025, and totaled approximately 2
Contract costs include all direct materials, labor, equipment and subcontracted costs, as well as indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and the operational costs of capital equipment. Cost estimation processes used for recognizing revenue over time under the cost-to-cost method require management to make significant assumptions and judgments. Total transaction price and cost estimation processes are based primarily on the professional knowledge and experience of the Company’s project managers, operational and financial professionals, and other professional expertise, as warranted. Management reviews estimates of total contract transaction price and costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of the estimated amount and probability of variable consideration are factors that influence estimates of the total contract transaction price, total costs to complete those contracts and the Company’s profit recognition. Changes in these factors could result in revisions to the amount of revenue recognized in the period in which the revisions are determined, which revisions could materially affect the Company’s consolidated results of operations for that period. Provisions for losses on uncompleted contracts are recorded in the period in which such losses are estimated based on management’s experience and judgment. In each of the years ended December 31, 2025, 2024 and 2023, project profit was affected by less than 5 0.8 %, 0.1 % and 0.2 %, respectively.
The Company may incur certain costs that can be capitalized, such as initial set-up or mobilization costs. Such capitalized costs, which are amortized over the life of the respective projects, were not material as of December 31, 2025 or 2024.
The timing of customer billings is generally dependent upon advance billing terms, milestone billings based on completion of certain phases of 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 by the Company as defined by each specific agreement. Progress payments, generally net of amounts retained, are paid by the customer over the duration of the contract. For install-to-the-home and certain other contracts and services, work orders are billed and paid as completed. Amounts billed and due from customers, as well as the value of contract assets, are generally classified within current assets in the consolidated balance sheets. See Note 5 - Accounts Receivable, Net of Allowance, and Contract Assets and Liabilities for related discussion. Amounts expected to be collected beyond one year are classified as other long-term assets.
Performance Obligations. A performance obligation is a contractual promise to transfer a distinct good or service to a customer. 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. The Company’s 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.
When more than one contract is entered into with a customer on or close to the same date, the Company evaluates whether those contracts should be combined and accounted for as a single contract, as well as whether those contracts should be accounted for as one, or more than one, performance obligation. This evaluation requires significant judgment and is based on the facts and circumstances of the specific contracts.
63
Remaining performance obligations represent the amount of unearned transaction prices under contracts for which work is wholly or partially unperformed, including the Company’s share of unearned transaction prices from its proportionately consolidated non-controlled joint ventures. As of December 31, 2025, the amount of the Company’s remaining performance obligations was $14.6 billion. Based on current expectations, the Company anticipates it will recognize approximately $9.3 billion, or 63.7 %, of its remaining performance obligations as revenue during 2026, with the majority of the remaining balance expected to be recognized over the subsequent two year period.
Variable Consideration. Transaction prices for the Company’s 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 it believes best predict the amount of consideration to which the Company 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 discussions, correspondence or preliminary negotiations and past practices with the customer, engineering studies and legal advice 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 recognized as an adjustment to revenue, typically 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 the Company’s 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, 2025 and 2024, the Company’s contract transaction prices included approximately $229 million and $139 million, respectively, of change orders and/or claims for certain contracts that were in the process of being resolved in the ordinary course of its 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 both December 31, 2025 and 2024, these change orders and/or claims primarily related to certain projects in the Company’s Clean Energy and Infrastructure and Power Delivery segments. The Company actively engages with its customers to complete the final approval process for such amounts and generally expects 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.
Allowance for Credit Losses
The Company maintains an allowance for credit losses for its financial instruments, which are primarily composed of accounts receivable and contract assets. The measurement and recognition of credit losses involves the use of judgment and incorporates management’s estimate of expected lifetime credit losses based on historical experience and trends, current conditions and reasonable and supportable forecasts. Management’s assessment of expected credit losses includes consideration of current and expected economic, market and industry factors affecting the Company’s customers, including their financial condition; the aging of account balances; historical credit loss experience; customer concentrations; customer credit-worthiness; availability of mechanics’ and other liens; and the existence of payment bonds and other sources of payment, among other factors. Management evaluates its experience with historical losses and then applies this historical loss ratio to financial assets with similar characteristics. The Company’s historical loss ratio or its determination of risk pools may be adjusted for changes in customer, economic, market or other circumstances. The Company may also establish an allowance for credit losses for specific receivables when it is probable that a specific receivable will not be collected and the loss can be reasonably estimated. Amounts are written off against the allowance when they are considered to be uncollectible, and reversals of previously reserved amounts are recognized if a specifically reserved item is settled for an amount exceeding the previous estimate.
Estimates of expected credit losses could be affected by many factors, including, but not limited to: changes in credit loss experience, changes to the risk characteristics of the Company’s financial instrument portfolio, developing trends, including changes in management’s expectations of future economic, industry or other conditions and/or changes in credit quality or unanticipated financial difficulties affecting the Company’s customers. In addition, if anticipated recoveries in existing negotiations or bankruptcies fail to materialize, additional allowances may be required. Estimates of collectibility are subject to significant change during times of economic weakness or uncertainty in either the overall economy or within the industries served by MasTec. Management actively monitors these factors and assesses the sufficiency of its allowance for credit losses on an ongoing basis, including the potential effects of trends in end-market volatility and/or other macroeconomic factors on the credit quality of the Company’s customers and/or its financial assets, such as the current market environment of elevated interest rates and inflation.
Inventories
Inventories primarily consist of materials and supplies for construction and installation projects, which are valued at the lower of cost or net realizable value using the average cost or specific identification methods of costing. For materials or supplies purchased on behalf of specific customers or projects, loss of the customer or cancellation of the project could result in an impairment of the value of materials purchased. The value of inventory may also decrease due to obsolescence, physical deterioration, damage, changes in price levels, or other causes.
Cash and Cash Equivalents
The Company considers highly liquid investments with original maturities of less than three months to be cash equivalents. The balances in certain of the Company’s bank accounts exceed federally insured limits. Cash and cash equivalents consist primarily of interest-bearing demand deposits that are maintained at financial institutions that management considers to be of high credit quality. Included in the Company’s cash balances as of December 31, 2025 and 2024 are amounts held by entities that are proportionately consolidated totaling $45.0 million and $46.7 million, respectively. These amounts are available to support the operations of those entities, but are not available for the Company’s other operations.
64
Fair Value of Financial Instruments
The Company’s financial instruments are primarily composed of cash and cash equivalents, accounts receivable and contract assets, notes receivable, cash collateral deposited with insurance carriers, life insurance assets, equity investments, certain other assets and investments, deferred compensation plan assets and liabilities, accounts payable and other current liabilities, acquisition-related contingent consideration and other liabilities, and debt obligations.
Fair value is the price that would be received to sell an asset or the amount paid to transfer a liability, also referred to as the “exit price,” in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: (i) Level 1 - quoted market prices in active markets for identical assets or liabilities; (ii) Level 2 - observable market-based inputs or other observable inputs, including quoted market prices for identical or similar assets or liabilities in markets that are not active; and (iii) Level 3 - significant unobservable inputs that cannot be corroborated by observable market data, which are generally determined using valuation models incorporating management estimates of market participant assumptions. In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Management’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.
Fair values of financial instruments are estimated using public market prices, quotes from financial institutions and other available information. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, accounts receivable and contract assets, accounts payable and other current liabilities approximate their fair values, and management also believes that the carrying values of notes and other receivables, cash collateral deposited with insurance carriers and outstanding balances on the Company’s credit and term loan facilities approximate their fair values, based on their specific asset and/or liability characteristics, including having terms consistent with current market conditions.
Investment and Strategic Arrangements
From time to time, the Company may participate in selected investment or strategic arrangements to expand its operations, service offerings, customer base or geographic reach, including arrangements that combine the Company’s skills and resources with those of others to allow for the performance of particular projects. The Company’s investment and strategic arrangements include equity interests in various business entities and participation in contractual joint ventures, some of which may involve the extension of loans or other types of financing arrangements.
For further information pertaining to the Company’s equity investments, see Note 4 - Fair Value of Financial Instruments.
65
Deferred Financing Costs
Other Long-Term Assets
Other long-term assets consist primarily of investments in unconsolidated entities, life insurance assets, deferred compensation plan assets, insurance recoveries/receivables, and other miscellaneous receivables.
Long-Lived Assets
The Company’s long-lived assets consist primarily of property and equipment, including finance lease assets, and other intangible assets, which are subject to amortization, consisting of customer relationships and backlog, trade names, pre-qualifications, non-compete agreements and others.
Other intangible assets are amortized over their useful lives, which are generally based on contractual or legal rights, in a manner consistent with the pattern in which the related benefits are expected to be consumed, or on a straight-line basis if that pattern cannot be reliably determined.
Goodwill
The Company has recorded goodwill in connection with its acquisitions of businesses. Goodwill is not amortized, but instead is tested for impairment at least annually. The Company performs its annual impairment test of goodwill during the fourth quarter of each year, or more frequently if events or circumstances arise which indicate that the fair value of a reporting unit with goodwill is below its carrying amount. See below for details of the Company’s impairment testing for the years ended December 31, 2025, 2024 and 2023.
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. Management identifies its reporting units by assessing whether components (i) have discrete financial information available; (ii) engage in business activities; and (iii) have a segment manager that regularly reviews the component’s operating results. If two or more components are deemed economically similar, those components are aggregated into one reporting unit when performing the annual goodwill impairment test. All of the Company’s reporting units are each composed of one component.
During each of the three years in the period ended December 31, 2025, as part of the Company’s annual impairment test of goodwill, management performed a qualitative assessment of its reporting units by examining relevant events and circumstances that could have an effect on a reporting unit’s fair value, such as: macroeconomic trends and events, including levels of inflation, market interest rates and/or supply chain disruptions; industry and/or market conditions, including the potential effects of regulatory and other uncertainties, such as uncertainty related to the implementation and pace of spending under governmental infrastructure programs and initiatives and project permitting issues; financial, competitive and other conditions, including declines in the operating performance of the Company’s reporting units, and/or long-term changes in consumer behavior; entity-specific events; and other relevant factors or events that could affect earnings and cash flows.
Quantitative testing was performed for selected reporting units during each of the three years in the period ended December 31, 2025. Management estimated the fair values of the selected reporting units using a combination of market and income approaches using Level 3 inputs. Under the market approach, fair values were estimated using published market multiples for comparable companies and applying them to revenue and earnings before interest, taxes, depreciation and amortization (“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, market and regulatory conditions; and (iii) the impact of planned business and operational strategies. Management believes the assumptions used in its quantitative goodwill impairment tests are reflective of the risks inherent in the business
66
models of the applicable reporting units and within the units’ industry. 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.
2025 Assessment. During the first quarter of 2025, certain reporting units within the Communications and Power Delivery operating segments were restructured to more closely align with the segments’ end markets and to better correspond with the operational management reporting structure of both segments. Under both the current and previous reporting unit structures, each of the components within the Communications and Power Delivery operating segments is a reporting unit. Management performed goodwill impairment testing under both the current and previous reporting unit structures. Based on the results of the quantitative assessments, the estimated fair values of the impacted reporting units substantially exceeded their carrying values as of March 31, 2025, therefore no goodwill impairment existed. A 1 00 basis point increase in the discount rate would not have resulted in any of the tested reporting units’ carrying values exceeding their fair values.
During the fourth quarter of 2025, the Company completed its annual impairment test of goodwill as part of which it performed a qualitative assessment of all reporting units and concluded that it was more likely than not that the fair value of each reporting unit was greater than its carrying value. Accordingly, a quantitative goodwill impairment test was not required for any of the reporting units, and no goodwill impairment was recognized in 2025.
2024 and 2023 Assessments. The Company completed its annual goodwill impairment test for all of its reporting units during both of the years ended December 31, 2024 and 2023. In 2024, quantitative testing was performed for (i) two reporting units within the Communications operating segment; (ii) one reporting unit within the Clean Energy and Infrastructure operating segment; and (iii) one reporting unit within the Pipeline Infrastructure operating segment. In 2023, quantitative testing was performed for (i) three reporting units within the Clean Energy and Infrastructure segment; (ii) one reporting unit in the Power Delivery operating segment; and (iii) one reporting unit within the Pipeline Infrastructure operating segment. The Company determined there was no
Additionally, during the first quarter of 2024, the reporting units within the Power Delivery operating segment were restructured to more closely align with the segment’s end markets and to better correspond with the operational management reporting structure of the segment, including from the effects of the Company’s transformative acquisition efforts in prior years. Management performed goodwill impairment testing under both the updated and previous reporting unit structures and determined that no goodwill impairment existed.
As of December 31, 2025 and 2024, management believes that the recorded goodwill balances are recoverable; however, significant changes in the assumptions or estimates used in the Company’s analyses, such as a reduction in profitability and/or cash flows, changes in market, regulatory or other conditions, including decreases in project activity levels and/or the effects of elevated levels of inflation, interest rates or other regulatory or market disruptions, including from geopolitical events and/or changes in asset characteristics, could result in non-cash goodwill impairment charges in future periods.
Business Combinations
The determination of the fair value of net assets acquired in a business combination 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. For current assets and current liabilities, book value is generally assumed to approximate fair value. Goodwill is the amount by which consideration paid for an acquired entity exceeds the fair value of its acquired net assets. A bargain purchase gain results when the fair value of an acquired entity’s net assets exceeds its purchase price, and is recorded within other income in the consolidated statements of operations. Acquisition costs are expensed as incurred and are included within general and administrative expenses in the consolidated statements of operations.
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 from the date of acquisition 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 of, or an adjustment to the fair values of, acquisition-related assets and liabilities and/or consideration paid, and are referred to as measurement period adjustments. Measurement period adjustments are recorded to goodwill. Other changes to fair value estimates, including those relating to facts and circumstances that occur subsequent to the date of acquisition, are reflected as income or expense in the consolidated statement of operations, as appropriate.
Consideration paid generally consists of cash and, from time to time, shares of the Company’s common stock, and potential future payments that are contingent upon the acquired business achieving certain levels of earnings in the future, also referred to as “acquisition-related contingent consideration” or “earn-outs.” Earn-out liabilities are measured at their estimated fair values as of the date of acquisition. Subsequent to the date of acquisition, if future Earn-out payments are expected to differ from Earn-out payments estimated as of the date of acquisition, any related fair value adjustments, including those related to finalization of completed earn-out arrangements, are recognized in the period that such expectation is considered probable. Changes in the fair value of Earn-out liabilities for the Company’s traditional earn-outs, other than those related to measurement period adjustments, as described above, are recorded within other income or expense in the consolidated statements of operations. Fair values of Earn-out liabilities are estimated using income approaches such as discounted cash flows or option pricing models, which are Level 3 inputs. Earn-out liabilities are included within other current and other long-term liabilities, as appropriate, within the consolidated balance sheets. Earn-out payments, to the extent they relate to estimated liabilities as of the date of acquisition, are classified within financing activities in the consolidated statements of cash flows. Earn-out payments in excess of acquisition date liabilities are classified within operating activities in the consolidated statement of cash flows.
67
Leases
In the ordinary course of business, the Company enters into agreements that provide financing primarily for machinery, equipment, and vehicles, including certain related party leases. The Company reviews all agreements to determine if a leasing arrangement exists. When a leasing arrangement is identified, a determination is made at inception as to whether the lease is an operating or a finance lease. A lease exists when a contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In determining whether a lease exists, the Company considers whether a contract provides both the right to obtain substantially all of the economic benefits from the use of an asset and the right to direct the use of the asset. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of the minimum future lease payments over the expected term of the lease. The Company’s lease assets are primarily concentrated in vehicles, machinery and equipment.
Leases with an initial term of twelve months or less are classified as short-term leases and are not recognized in the consolidated balance sheets unless the lease contains a purchase option that is reasonably certain to be exercised, or unless it is reasonably certain that the equipment will be leased for greater than twelve months. The volume of lease activity for leases with an initial term of twelve months or less varies depending upon the number of ongoing projects at a given time, as well as the location and type of equipment required in connection with those projects. Lease payments for short-term leases are recognized on a straight-line basis over the lease term, and primarily relate to equipment used on construction projects, for which the rentals are based on daily, weekly or monthly rental rates, and typically contain termination for convenience provisions. Lease determinations are reassessed in the event of a change in lease terms. The Company has a limited number of sublease, equipment and other leasing arrangements, which are not considered material to the consolidated financial statements.
As of December 31, 2025, the Company’s leases have remaining lease terms of up to 13 years. Lease agreements may contain renewal clauses, which, if elected, generally extend the term of the lease for 1 5
Lease term, discount rate, variable lease costs and future minimum lease payment determinations require the use of judgment, and are based on the facts and circumstances of each lease. Economic incentives, intent, past history and business needs are among the factors considered to determine if renewal and/or purchase options are reasonably certain to be exercised. The majority of the Company’s lease agreements do not explicitly state the discount rate implicit in the lease, therefore, the Company generally uses an incremental borrowing rate to determine the value of its lease obligations. The incremental borrowing rate represents the rate of interest that would be paid to borrow on a collateralized basis over a similar term. The Company determines its incremental borrowing rate using a portfolio approach based on information available as of the lease commencement date, including applicable lease terms and the current economic environment.
Finance Leases. Finance lease assets are recorded within property and equipment, with a corresponding amount recorded within the Company’s debt obligations. Finance lease expense is composed of depreciation expense on the leased asset and interest on the lease liability. Additions to finance leases are included within the supplemental disclosures of non-cash information in the consolidated statements of cash flows. Many of the Company’s finance leases contain a purchase option which the Company is reasonably certain to exercise at the end of the lease term, given that the purchase option prices are typically below the estimated fair market values of the related assets.
Operating Leases. Operating lease right-of-use assets and liabilities are recorded on the consolidated balance sheets, with the related lease expense recognized over the term of the lease on a straight-line basis. Operating lease expense is recorded as rent expense, primarily within costs of revenue, excluding depreciation and amortization. Fixed costs for operating leases are composed of initial base rent amounts plus any fixed annual increases. Variable costs for operating leases consist primarily of common area maintenance expenses and taxes for facility leases. Certain of the Company’s operating leases contain purchase options, for which the purchase option price is generally considered to be at fair market value. From time to time, the Company may terminate a lease before the end of the lease term. Payments related to such early lease terminations are generally recorded within general and administration expenses.

Self-Insurance
The Company is self-insured up to the amount of its deductible for its insurance policies. MasTec maintains insurance policies subject to per claim deductibles of $2.0 million for its workers’ compensation policy and $25.0
Estimated liabilities under the Company’s insurance programs are accrued based upon management’s estimates of the ultimate liability for claims reported and an estimate of claims incurred but not reported, with assistance from third-party actuaries. For claims in excess of the deductible amounts, the Company records a receivable representing estimated recoveries associated with workers’ compensation, general liability and automobile claims. MasTec also maintains an insurance policy with respect to employee group medical claims, which is subject to annual per employee maximum losses of $0.6 million. MasTec’s estimated liability for employee group medical claims is based on statistical analysis of historical claims experience and specific knowledge of actual losses that have occurred. The Company is required to post collateral, generally in the form of letters of credit, surety bonds and cash to certain of its insurance carriers. Cash collateral deposited with insurance carriers is included in other long-term assets in the consolidated balance sheets.
The present value of the Company’s self-insurance liability is reflected in the consolidated balance sheets within current and other long-term liabilities, as appropriate. The determination of such claims and expenses and the appropriateness of the related liability is reviewed and updated quarterly. These insurance liabilities are, however, difficult to assess and estimate due to many factors, the effects of which are often unknown or difficult to estimate, including the severity of an injury or an incident, the determination of the Company’s liability in proportion to other parties and the number of incidents not reported. Accruals are based upon known facts, historical trends and claims experience, loss development patterns and other actuarial assumptions. Although management believes its accruals are adequate, a change in experience or actuarial or management assumptions could materially affect the Company’s results of operations in a particular period.
Income Taxes
The Company records income taxes using the asset and liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement and income tax basis of the Company’s assets and liabilities. Income taxes are estimated in each of the jurisdictions in which the Company operates. This process involves estimating the tax exposure, together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included, net, within the consolidated balance sheets as long-term assets or liabilities, as appropriate. The recording of a deferred tax asset assumes the realization of such asset in the future. Otherwise, a valuation allowance is recorded to reduce the asset to its estimated net realizable value. If management determines that the Company may not be able to realize all or part of a deferred tax asset in the future, a valuation allowance for the deferred tax asset is charged to income tax expense in the period the determination is made. Management considers future pretax income and ongoing prudent and feasible tax planning strategies in assessing the estimated net realizable value of tax assets and the corresponding need for any related valuation allowances.
In determining the provision for income taxes, management 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 the Company operates. The Company is generally free of additional U.S. federal tax consequences on distributed foreign subsidiary earnings. The Company has generally not provided for U.S. income taxes on unremitted foreign earnings because such earnings are considered to be insignificant.
Significant factors that can affect the Company’s annual effective tax rate include management’s assessment of certain tax matters, the location and amount of taxable earnings, changes in certain non-deductible expenses and expected credits.
An entity may only recognize or continue to recognize tax positions that meet a "more likely than not" threshold. In the ordinary course of business, there is inherent uncertainty in quantifying income tax positions. The Company assesses its income tax positions and records tax benefits for all years subject to examination based on management's 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, the Company has 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 the Company's financial statements.
The Company and its subsidiaries file income tax returns in numerous tax jurisdictions, including U.S. federal, most U.S. states and certain foreign jurisdictions. Although management believes its calculations for its tax returns are accurate and the positions taken thereon are reasonable, the final outcome of income tax examinations could be materially different from the resolution management currently anticipates and the estimates that are reflected in the Company’s consolidated financial statements, which could materially affect the Company’s results of operations, cash flows and liquidity in a particular period. To the extent interest and penalties are assessed by taxing authorities, such amounts are accrued and included within income tax expense.
Stock-Based Compensation
The Company has certain stock-based compensation plans, under which restricted stock awards and restricted stock units (together, “restricted shares”) are available for issuance to eligible participants. Non-cash stock-based compensation expense is included within general and administrative expense in the consolidated statements of operations. Share-based payments, to the extent they are compensatory, are recognized based on their grant date fair values. Forfeitures are recorded as they occur. The Company records a deferred tax asset, or future tax benefit, based on the amount of share-based compensation recognized in the financial statements over the vesting period of share-based awards. The tax effects of differences between the fair value of a share-based award on the date of vesting and the date of grant, also referred to as excess tax benefits or tax deficiencies, are recognized within the provision for income taxes in the period such vesting occurs.
69
Grants of restricted shares are valued based on the closing market share price of MasTec’s common stock as reported on the New York Stock Exchange (the “market price”) on the date of grant. Compensation expense arising from restricted shares is recognized on a straight-line basis over the vesting period. Grants of restricted shares have cliff vesting terms, which generally vest over a period of three years . Upon vesting, some of the underlying shares may be sold to cover the required tax withholdings. Some participants may choose the net share settlement method to cover withholding tax requirements, in which case shares are not issued, but are treated as common stock repurchases in the consolidated financial statements, as they reduce the number of shares that would have been issued upon vesting. The Company then pays the corresponding withholding taxes to the appropriate taxing authorities in cash on behalf of the recipient. Withheld shares, which are valued at the market price on the trading day preceding the vesting date, are recorded as a reduction to additional paid-in capital, and related payments to taxing authorities are reflected within financing activities in the consolidated statements of cash flows. For the years ended December 31, 2025, 2024 and 2023, shares withheld in connection with stock-based compensation arrangements totaled 42,503 , 33,451 and 118,636 , respectively, and related payments to taxing authorities totaled $5.6 million, $2.9 million and $10.3 million, respectively.
The Company has certain employee stock purchase plans (collectively, “ESPPs”) under which shares of the Company’s common stock are available for purchase by eligible participants. Under the ESPPs, eligible participants are permitted to purchase MasTec, Inc. common stock at 85 % of the fair market value of the shares on the date of purchase, which occurs on the last trading day of each two week offering period. At the Company’s discretion, share purchases may be satisfied by delivering either newly issued common shares, or common shares reacquired on the open market or in privately negotiated transactions.
Collective Bargaining Agreements and Multiemployer Plans
Certain of MasTec’s subsidiaries, including certain subsidiaries in Canada, are party to various collective bargaining agreements with unions representing certain of their employees. These agreements require the subsidiaries party to the agreements to pay specified wages, provide certain benefits to their union employees and contribute certain amounts to multiemployer pension and other multiemployer benefit plans and trusts (“MEPPs”). These contributions are recorded as a component of employee wages and salaries within costs of revenue, excluding depreciation and amortization. Contributions are generally based on fixed amounts per hour per employee for employees covered under these plans. Multiemployer plan contribution rates are determined annually and are assessed on a “pay-as-you-go” basis based on union employee payrolls. The Pension Protection Act of 2006, as amended (the “PPA”), requires underfunded pension plans 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 (the “IRS”) can impose on the employers contributing to such plans a non-deductible excise tax of 5% of the amount of the accumulated funding deficiency. Union payrolls cannot be determined for future periods because the number of union employees employed at a given time, and the plans in which they participate, vary depending upon the location and number of ongoing projects and the need for union resources in connection with those projects. The collective bargaining agreements expire at various times and have typically been renegotiated and renewed on terms similar to the ones contained in the expiring agreements.
Litigation and Contingencies
Accruals for litigation and contingencies are reflected in the consolidated financial statements based on management’s assessment, including advice of legal counsel, of the expected outcome of litigation or other dispute resolution proceedings and/or the expected resolution of contingencies. Costs incurred for litigation are expensed as incurred. Liabilities for estimated losses are accrued if the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated. Significant judgment is required in both the determination of probability of loss and the determination as to whether the amount is reasonably estimable. Accruals are based on information available at the time of the assessment due to the uncertain nature of such matters. As additional information becomes available, management reassesses potential liabilities related to pending claims and litigation and may revise its previous estimates, which could materially affect the Company’s results of operations in a given period.
Comprehensive Income (Loss)
Comprehensive income or loss is a measure of net income and other changes in equity that result from transactions other than those with shareholders. Comprehensive income or loss and related accumulated comprehensive income or loss balances consist of net income, foreign currency translation adjustments, primarily from fluctuations in foreign currency exchange rates of the Company’s foreign subsidiaries with a functional currency other than the U.S. dollar, and unrealized gains and losses from certain investment activities.

Recent Accounting Pronouncements
See the recent accounting pronouncements discussion below for information pertaining to the effects of recently adopted and other recent accounting pronouncements.
Accounting Pronouncements Adopted in 2025
In August 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-05, Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement (“ASU 2023-05”) to clarify existing guidance and reduce diversity in practice in the accounting for joint ventures. ASU 2023-05 addressed the accounting for contributions made to a joint venture upon formation in a joint venture’s separate financial statements. The provisions of this ASU required that a joint venture initially measure all contributions received upon its formation at fair value, largely consistent with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”). The amendments in this ASU were not applicable to the formation of proportionately consolidated joint ventures. ASU 2023-05 was effective prospectively for all joint ventures with a formation date on or after January 1, 2025, with early adoption permitted on a retrospective basis for joint ventures formed before January 1, 2025. The Company adopted this ASU prospectively in the first quarter of 2025, and its adoption did not have a material effect on the Company’s consolidated financial statements.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”) to enhance transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires greater standardization and disaggregation of categories within an entity’s tax rate reconciliation disclosure, as well as disclosure of income taxes paid by jurisdiction, among other requirements. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. ASU 2023-09 was effective on a prospective basis, with retrospective application permitted. The Company adopted this ASU prospectively as of and for the year-ended December 31, 2025, and its adoption only impacted the Company’s disclosures, and did not have a material effect on its consolidated financial statements or results of operations. See Note 13 - Income Taxes for additional information.
Recently Issued Accounting Pronouncements Not Yet Adopted
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”) to enhance the transparency and clarity of the components of specific expense categories in the income statement. ASU 2024-03 requires disclosure of additional information about specific expense categories underlying certain income statement expense line items. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses: Clarifying the Effective Date to clarify that all public business entities are required to adopt the guidance in annual periods beginning after December 15, 2026, and interim periods within annual periods beginning after December 15, 2027. Early adoption is permitted. The amendments in ASU 2024-03, and its related clarifying ASU, should be applied prospectively, with retrospective application permitted. The Company is currently evaluating the impact this ASU will have on its disclosures.
In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity (“ASU 2025-03”). ASU 2025-03 clarifies the guidance in determining the accounting acquirer in a business combination effected primarily by exchanging equity interests when the acquiree is a variable interest entity that meets the definition of a business. ASU 2025-03 is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. ASU 2025-03 is required to be applied prospectively to any acquisition transaction that occurs after the initial application date. The Company does not expect that this ASU will have a material effect on its consolidated financial statements.
In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). ASU 2025-05 provides a practical expedient that permits an entity to assume that conditions at the balance sheet date remain unchanged over the life of the asset when estimating expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The amendments in ASU 2025-05 should be applied prospectively. The Company does not expect that this ASU will have a material effect on its consolidated financial statements.
In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 modernizes the accounting for internal-use software by eliminating the previous stage-based capitalization model so that the guidance is neutral to different software development methods. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. The amendments in ASU 2025-06 should be applied prospectively, with retrospective application or a modified transition approach permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 improves existing guidance within ASC Topic 270 by clarifying the scope and applicability of the standard and by providing a comprehensive list of interim disclosure requirements. ASU 2025-11 also establishes a principle to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.

Note 2 – Earnings Per Share
Basic earnings or loss per share is computed by dividing net income or loss attributable to MasTec by the weighted average number of common shares outstanding for the period, which excludes non-participating unvested restricted share awards. Diluted earnings per share is computed by dividing net income attributable to MasTec by the weighted average number of fully diluted shares, as calculated primarily under the treasury stock method, which includes the potential effect of dilutive common stock equivalents, such as issued but unvested restricted shares. If the Company reports a loss, rather than income, the computation of diluted loss per share excludes the effect of dilutive common stock equivalents if their effect would be anti-dilutive.
The following table provides details underlying the Company’s earnings per share calculations for the periods indicated (in thousands):

Share repurchases. For the year ended December 31, 2025, the Company repurchased 702,533 shares of its common stock, the effect of which on the Company’s weighted average shares outstanding for the related period was a reduction of approximately 539,000 shares.

Recent Acquisitions
The Company seeks to grow and diversify its business both organically and through acquisitions and/or strategic arrangements in order to deepen its market presence and customer base, broaden its geographic reach and expand its service offerings. Acquisitions are funded with cash on hand, borrowings under the Company’s senior unsecured credit facility and other debt financing and, for certain acquisitions, with shares of the Company’s common stock, and are generally subject to customary purchase price adjustments. The goodwill balances for each of the respective acquisitions represent the estimated values of each acquired company’s geographic presence in key markets, assembled workforce, synergies expected to be achieved from the combined operations of each of the acquired companies and MasTec, as well as the acquired company’s industry-specific project management expertise.
Q1 2026 Acquisitions. Subsequent to December 31, 2025, MasTec acquired 86 % of the equity interest of an infrastructure services company that specializes in water and wastewater distribution networks in the south central region of the United States, which will be included within the Company’s Clean Energy and Infrastructure segment, effective in January. MasTec has the option to acquire the remaining noncontrolling interest in the entity following the third anniversary of the consummation date. The aggregate purchase price of this acquisition was $262 million and consisted of cash paid or payable on the date of the acquisition. The final amount of consideration for this acquisition remains subject to certain post-closing adjustments, including with respect to net working capital, tax estimates and other contractually agreed-upon adjustments to consideration. The Company accounted for the acquisition of the ownership interest as a business combination in accordance with ASC 805 and will consolidate the results of this entity in its consolidated financial statements. The preliminary fair value of the noncontrolling interest is estimated at $42 million, and is based on the price MasTec paid for its 86 % controlling interest. The Company is in the process of performing procedures to determine the fair value of assets acquired and liabilities assumed related to this acquisition, and will include the preliminary purchase price allocations in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2026.
73
2025 Acquisitions. During 2025, MasTec acquired all of the equity interests of the following: (i) within the Company’s Communications segment: a telecommunications construction company, effective in July; (ii) within the Company’s Pipeline Infrastructure segment: a construction company specializing in roadway infrastructure, effective in August; and (iii) within the Company’s Clean Energy and Infrastructure segment: a construction company specializing in construction management and design-build services, effective in December. Additionally, MasTec acquired certain operations and assets of a business specializing in install-to-the-home services included within the Company’s Communications segment, effective in November. Determination of the estimated fair values of net assets acquired and consideration transferred for these acquisitions, which have been accounted for as business combinations under ASC 805, was preliminary as of December 31, 2025; as a result, further adjustments to these estimates may occur. The Company expects to finalize the valuation and complete the purchase price consideration allocation no later than one year from the acquisition date.
Additionally, effective in July, MasTec acquired certain of the assets of an equipment company, which is accounted for as an asset acquisition under ASC 805 and included within the Company’s Pipeline Infrastructure segment.
The aggregate purchase price of the Company’s 2025 acquisitions was composed of approximately $87 million, in cash, net of cash acquired, and a five year earn-out liability valued at approximately $13 million primarily with respect to one of such acquisitions. As of December 31, 2025, the remaining potential undiscounted earn-out liabilities for the 2025 acquisitions was estimated to be up to $20 million; however, there is no maximum payment amount. See Note 4 - Fair Value of Financial Instruments for fair value estimates and other details related to the Company’s earn-out arrangements. Approximately $33 million of the goodwill balance related to the 2025 acquisitions is expected to be tax deductible as of December 31, 2025.
2024 Acquisitions. During 2024, MasTec completed three acquisitions, which included all of the equity interests of a construction company focused on underground utility infrastructure for industrial and municipal projects, with expertise in data center utility systems, which acquisition is included within the Company’s Power Delivery segment, and was effective in July; the acquisition of certain operations of a heavy civil contractor specializing in transportation projects, which acquisition is included within the Company’s Clean Energy and Infrastructure segment and was effective in October; and effective in December, the acquisition of the equity interests of a company focused on pipeline infrastructure and heavy civil projects, which acquisition is included within the Company’s Pipeline Infrastructure segment.
The aggregate purchase price of the Company’s 2024 acquisitions was composed of approximately $88 million in cash, net of cash acquired, and a five year earn-out liability valued at approximately $56 million with respect to one of such acquisitions. In connection with the acquisition within the Company’s Pipeline Infrastructure segment, MasTec acquired 60 % of the equity interest of the company in exchange for consideration transferred of cash and a 40 % equity interest in a MasTec Canadian subsidiary. Determination of the estimated fair values of net assets acquired and consideration transferred for these acquisitions, which have been accounted for as business combinations under ASC 805, was complete as of December 31, 2025. As of December 31, 2025, the remaining potential undiscounted earn-out liabilities for the 2024 acquisitions was estimated to be up to $27 million; however, there is no maximum payment amount. See Note 4 - Fair Value of Financial Instruments for fair value estimates and other details related to the Company’s earn-out arrangements. Approximately $47 million of the goodwill balance related to the 2024 acquisitions is expected to be tax deductible as of December 31, 2025.
2023 Acquisitions. During 2023, MasTec completed four acquisitions, including the acquisition of certain assets of a telecommunications company specializing in wireless services, which acquisition was included within the Company’s Communications segment, and was effective in January; and, effective in July, the acquisition of the equity interests of a telecommunications construction company specializing in broadband and fiber-to-the-home initiatives in the New England area, which acquisition was included within the Company’s Communications segment. Additionally, effective in May 2023, MasTec acquired certain of the equity interests of two equipment companies which were accounted for as asset acquisitions under ASC 805 and were included within the Company’s Pipeline Infrastructure segment. In the fourth quarter of 2023, the Company sold certain of the equity interests of these equipment companies to members of subsidiary management. See Note 16 - Related Party Transactions. Based on an evaluation of the respective entities’ operating agreements, the Company determined that these entities are not VIEs; however, given that the Company has voting control with respect to the entities, the Company has consolidated these entities within the Company’s results of operations, with the other parties’ interests accounted for as non-controlling interests.
The aggregate purchase price of the Company’s 2023 acquisitions was composed of $70 million in cash, net of cash acquired, and an earn-out liability valued at $1 million. As of December 31, 2025, the remaining potential undiscounted earn-out liabilities for the 2023 acquisitions was estimated to be up to $0.3 million; however, there is no maximum payment amount. See Note 4 - Fair Value of Financial Instruments for fair value estimates and other details related to the Company’s earn-out arrangements. Approximately $41 million of the goodwill balance related to the 2023 acquisitions is expected to be tax deductible as of December 31, 2025.
HMG Additional Payments. The 2021 HMG purchase agreement provides for certain additional payments to be made to the sellers if certain receivables are collected by the Company (the “Additional Payments”). Pursuant to the terms of the purchase agreement, a portion of the Additional Payments will be made in cash, with the remainder due in shares of MasTec common stock. The estimated number of potential shares that could be issued related to such Additional Payments will be based on the amounts ultimately collected and the share price as defined within the purchase agreement. Changes in the estimated fair value of potential shares that could be issued, which result from changes in MasTec’s share price as compared with the share price as defined within the purchase agreement, are reflected as unrealized gains or losses within other income or expense, as appropriate. As of December 31, 2025 and 2024, the estimated fair value of remaining Additional Payments totaled approximately $18 million and $14 million, respectively, which amounts are included within other current liabilities in the consolidated balance sheet. In November 2024, the Company made Additional Payments of approximately $26 million, which were composed of cash payments of approximately $12 million, and are reflected within financing activities in the consolidated statement of cash flows, and MasTec common stock totaling approximately 93,000 shares. For the years ended December 31, 2025 and 2024, fair value adjustments related to the contingent shares totaled losses of approximately $4.1 million and $5.5 million, respectively, and for the year ended December 31, 2023, fair value adjustments related to the contingent shares totaled gains of approximately $1.3 million. The estimated number of shares that would be paid in connection with the remaining Additional Payment liability

Pro forma results. The Company’s unaudited pro forma financial results include the results of operations of acquired companies as if those companies had been consolidated as of the beginning of the year prior to their acquisition, and are provided for illustrative purposes only. These unaudited pro forma financial results do not purport to be indicative of the actual results that would have been achieved by the combined companies for the periods indicated, or of the results that may be achieved by the combined companies in the future.
The following table provides unaudited supplemental pro forma results for the periods indicated (in millions):

The Company’s unaudited pro forma financial results were prepared by adding the unaudited historical results of acquired businesses to the historical results of MasTec, and then adjusting those combined results for (i) acquisition costs; (ii) amortization expense from acquired intangible assets; (iii) interest expense from cash consideration paid; (iv) interest expense from debt repaid upon acquisition; and (iv) other purchase accounting related adjustments. These unaudited pro forma financial results do not include adjustments to reflect other cost savings or synergies that may have resulted from these acquisitions. Future results may vary significantly due to future events and other factors, many of which are beyond the Company’s control.
Acquisition-related results. The Company defines “acquisition-related” results as results from acquired businesses for the first twelve months following the dates of the respective acquisitions. For the years ended December 31, 2025, 2024 and 2023, the Company’s consolidated results of operations included acquisition-related revenue of approximately $166.4 million, $42.8 million and $1,546.3 million, respectively. Acquisition-related revenue for the year ended December 31, 2023 included approximately $1,374.6 million for IEA. For both the years ended December 31, 2025 and 2024, acquisition-related net income was immaterial 40.0 million, based on the Company’s consolidated effective tax rates. These acquisition-related results include amortization of acquired intangible assets and certain acquisition integration costs, and exclude the effects of interest expense associated with consideration paid for the related acquisitions.
Revenue and net income from the Company’s 2025 acquisitions included within the Company’s consolidated results of operations for the year ended December 31, 2025 were immaterial
Acquisition and integration costs. For the year ended December 31, 2025, the Company incurred approximately $4 million of acquisition costs, and for both the years ended December 31, 2024 and 2023, the Company incurred approximately $3
In 2021, the Company initiated a significant transformation of its end-market business operations to position the Company for expected future growth opportunities. This transformation included significant business combination activity, including expansion of the Company’s scale and capacity in renewable energy, power delivery, heavy civil and telecommunications services, which activity resulted in significant acquisition and integration costs in prior periods. These acquisition and integration activities were completed in the fourth quarter of 2023. Acquisition and integration costs for the year ended December 31, 2023 totaled approximately $71.9 million, of which $64.1 million was included within general and administrative expenses and $7.8 million was included within costs of revenue, excluding depreciation and amortization.
Note 4 – Fair Value of Financial Instruments
Acquisition-Related Contingent Consideration
Acquisition-related contingent consideration is composed of earn-outs, which represent the estimated fair value of future amounts payable for businesses, which the Company refers to as “Earn-outs,” that are contingent upon the acquired businesses achieving certain levels of earnings in the future. The fair values of the Company’s Earn-out liabilities are estimated using income approaches such as discounted cash flows or option pricing models, both of which incorporate significant inputs not observable in the market (Level 3 inputs), including management’s estimates and entity-specific assumptions, and are evaluated on an ongoing basis. Key assumptions include the discount rate, which, as of December 31, 2025, ranged from 10.5 % to 14.3 %, with a weighted average rate of 11.1 % based on the relative fair value of the respective Earn-out liabilities, and probability-weighted projections of EBITDA. Significant changes in any of these assumptions could result in significantly higher or lower estimated Earn-out liabilities. The ultimate payment amounts for the Company’s Earn-out liabilities will be determined based on the actual results achieved by the acquired businesses. As of December 31, 2025, the range of potential undiscounted Earn-out liabilities was estimated to be between $21 million and $88 million; however, there is no maximum payment amount.
75
Earn-out activity consists primarily of additions from new business combinations; changes in the expected fair value of future payment obligations; and payments. The following table, which may contain slight summation differences due to rounding, provides a reconciliation of changes in Earn-out liabilities measured at fair value for the periods indicated (in millions):

Equity Investments
The Company’s equity investments as of December 31, 2025 include the Company’s: (i) 33 % equity interests in Trans-Pecos Pipeline, LLC and Comanche Trail Pipeline, LLC, collectively “Waha JVs”; (ii) 15 % equity interest in Cross Country Infrastructure Services, Inc. (“CCI”); (iii) 50 % equity interests in each of FM Technology Holdings, LLC, FM USA Holdings, LLC and All Communications Solutions Holdings, LLC, collectively “FM Tech”; (iv) interests in certain proportionately consolidated non-controlled joint ventures; and (v) certain other equity investments.
In the fourth quarter of 2025, the Company acquired a 15 % interest in a battery recycling company, which is accounted for as an equity method investment, through the conversion of approximately $49 million of outstanding accounts receivable. The effect of this transaction is excluded from investing activities in the Company’s consolidated statements of cash flows given its non-cash nature. The fair value of the 15 % equity interest received represented the carrying value of the accounts receivable at conversion, and accordingly no gain or loss was recognized.
As of December 31, 2025 and 2024, the aggregate carrying value of the Company’s equity investments, which are recorded within other long-term assets in the consolidated balance sheets, totaled approximately $377 million and $330 million, respectively. As of December 31, 2025 and 2024, equity investments measured on an adjusted cost basis, including the Company’s $15 19 million and $18 million, respectively. Except for one investment for which the Company recorded an impairment loss totaling approximately $3 million during the year ended December 31, 2023, there were no
The Waha JVs. The Waha JVs own and operate certain pipeline infrastructure in the U.S. that transports natural gas to the Mexico border for export. The Company’s investments in the Waha JVs are accounted for as equity method investments. Cumulative undistributed earnings from the Waha JVs, which represents cumulative equity in earnings for the Waha JVs less distributions of earnings, totaled $146.8 million as of December 31, 2025. The Company’s net investment in the Waha JVs, which differs from its proportionate share of the net assets of the Waha JVs due primarily to equity method goodwill associated with capitalized investment costs, totaled approximately $290 million and $287 million as of December 31, 2025 and 2024, respectively. The table below reflects the investment activity of the Waha JVs for the dates indicated (in millions):

(a)Equity in earnings related to the Company’s proportionate share of income from the Waha JVs is included within the Company’s Other segment.
(b)Distributions of earnings from the Waha JVs are included within operating cash flows.
The Waha JVs are party to separate non-recourse financing facilities, each of which are secured by pledges of the equity interests in the respective entities, as well as a first lien security interest over virtually all of their assets. The Waha JVs are also party to certain interest rate swaps (the “Waha JV swaps”), which are accounted for as qualifying cash flow hedges. The Company reflects its proportionate share of any unrealized fair market value gains or losses from fluctuations in interest rates associated with these swaps within other comprehensive income or loss, as appropriate. For the years ended December 31, 2025 and 2023, the Company’s proportionate share of unrecognized unrealized activity on the Waha JV swaps totaled losses of approximately $8.0 million and $5.0 million, respectively, or $6.0 million and $3.7 million, net of tax, respectively, and for the year ended December 31, 2024, such activity totaled gains of approximately $0.5 million, or $0.3 million, net of tax.
76
Other Investments. The Company has equity interests in certain other entities that are accounted for as equity method investments. As of December 31, 2025 and 2024, the Company had an investment of approximately $15 million and $17 million, respectively, in FM Tech, which provides for additional funding upon the resolution of certain contingencies, which could range up to $7 million as of December 31, 2025. The fair value of the remaining contingent payments for FM Tech, which are included within other current liabilities, was estimated to be $3 0.4 million and $0.2 million, respectively, to these other entities, and for the year ended December 31, 2025, there were no equity contributions to these entities. For the years ended December 31, 2025 and 2024, distributions from these entities totaled approximately $0.5 million and $1.9 million, respectively, and for the year ended December 31, 2023, there were no distributions from these entities. The Company has subcontracting arrangements with certain of these entities for the performance of construction services, and expenses recognized in connection with these arrangements totaled approximately $3.8 million, $5.4 million and $2.7 million for the years ended December 31, 2025, 2024 and 2023, respectively. As of both December 31, 2025 and 2024, related amounts payable to these entities totaled approximately $0.3 0.1 million and $0.7 million, respectively, and there were no such amounts for the year ended December 31, 2025. As of December 31, 2025 and 2024, receivables related to these arrangements totaled approximately $4.0 million and $4.1 million, respectively.
Variable Interest Entities. The Company has determined that certain of its investment arrangements are VIEs. See Note 1 - Business, Basis of Presentation and Significant Accounting Policies for additional information. As of December 31, 2025, management determined that the Company is the primary beneficiary of two of its VIEs, and accordingly, has consolidated these entities within the Company’s financial statements, with the other parties’ interests accounted for as non-controlling interests.
The Company’s consolidated VIEs include an electric utility contractor in which the Company acquired a 49 % interest in 2024. As of December 31, 2025 and 2024, the carrying values of assets associated with the Company’s consolidated VIEs totaled approximately $187.3 million and $134.8 million, respectively, which amounts consisted primarily of accounts receivable, net of allowance and contract assets. The carrying values of liabilities associated with the Company’s consolidated VIEs totaled approximately $184.6 million and $132.8 million as of December 31, 2025 and 2024, respectively, which amounts consisted primarily of accounts payable. The Company has not provided, nor is it obligated to provide, any financial support to any of its consolidated VIEs.
The carrying values of the Company’s VIEs that are not consolidated totaled approximately $20 million and $23 million as of December 31, 2025 and 2024, respectively, which amounts are recorded within other long-term assets in the consolidated balance sheets. Management believes that the Company’s maximum exposure to loss for its non-consolidated VIEs, inclusive of additional financing commitments, approximated $28 million and $34 million as of December 31, 2025 and 2024, respectively.
Senior Notes
The estimated fair values of the Company’s senior notes were determined based on an exit price approach using Level 2 inputs. See Note 8 - Debt for additional information pertaining to the Company’s senior notes.
Note 5 – Accounts Receivable, Net of Allowance, and Contract Assets and Liabilities
The following table provides details of accounts receivable, net of allowance, and contract assets (together “accounts receivable, net”) as of the dates indicated (in millions):

Accounts receivable, net of allowance | $ | $ | |||||||||
Retainage | $ | $ | |||||||||
Unbilled receivables | |||||||||||
| Contract assets | $ | $ | |||||||||
Contract billings represent the amount of performance obligations that have been billed but not yet collected, whereas contract assets consist of unbilled receivables and retainage. Unbilled receivables, which are included in contract assets, represent the estimated value of unbilled work for projects with performance obligations recognized over time. Unbilled receivables include amounts for work performed for which the Company has an unconditional right to receive payment and that are not subject to the completion of any other specific task, other than the billing itself. Retainage represents a portion of the contract amount that has been billed, but for which the contract allows the customer to retain a portion of the billed amount until final contract settlement, which is generally from 5 % to 10 % of contract billings. Retainage is not considered to be a significant financing component because the intent is to protect the customer. Unbilled receivables and retainage amounts are generally classified as current assets within the Company’s consolidated balance sheets. Retainage that has been billed, but is not due until completion of performance and acceptance by customers, is generally expected to be collected within one year . Accounts receivable balances expected to be collected beyond one year are recorded within other long-term assets. As of December 31, 2025, 2024 and 2023, contract assets totaled approximately $2,001.9 million, $1,555.8 million and $1,756.4 million, respectively. The increase in contract assets as of December 31, 2025, was driven primarily by ordinary course activity, including in connection with increased project volume primarily within the Company’s Communications segment.
77
For the year ended December 31, 2025, provisions for credit losses totaled a recovery of approximately $0.5 million, and for the year ended December 31, 2024, provisions for credit losses totaled approximately $4.8 million, both of which included certain project-specific reserves. For the years ended December 31, 2025 and 2024, amounts charged against the allowance, including direct write-offs, totaled approximately $0.7 million and $0.8 million, respectively. Impairment losses on contract assets were not material in any of the years ended December 31, 2025, 2024 or 2023.
Contract liabilities, which are generally classified within current liabilities on the Company’s consolidated balance sheets, consist primarily of deferred revenue and also include the amount of any accrued project losses. Under certain contracts, the Company may be entitled to invoice the customer and receive payments in advance of performing the related contract work. In those instances, the Company recognizes a liability for advance billings in excess of revenue recognized, which is referred to as deferred revenue. Deferred revenue is not considered to be a significant financing component because it is generally used to meet working capital demands that can be higher in the early stages of a contract. Total contract liabilities, including accrued project losses, totaled approximately $747.7 million, $735.6 million and $481.0 million as of December 31, 2025, 2024 and 2023, respectively, of which deferred revenue comprised approximately $741.0 million, $725.1 million and $475.2 million, respectively. For the years ended December 31, 2025, 2024 and 2023, the Company recognized revenue of approximately $705.6 million, $416.8 million and $363.3 million, respectively, related to amounts that were included in deferred revenue as of December 31, 2024, 2023 and 2022, respectively, resulting primarily from the advancement of physical progress on the related projects during the respective periods.
The Company is party to certain non-recourse financing arrangements in the ordinary course of business, under which certain receivables are sold to a financial institution in return for a nominal fee. The Company has certain additional non-recourse financing arrangements under which it continues to manage collections for the transferred receivables, and for which the corresponding servicing assets or liabilities are not material. For the years ended December 31, 2025, 2024 and 2023, the Company sold approximately $555 million, $442 million and $131 million, respectively, of receivables under financing arrangements for which it continues to manage collections for the transferred receivable, and, as of December 31, 2025 and 2024, outstanding sold receivables related thereto totaled approximately $172 million and $84 million, respectively, which amounts are excluded from accounts receivable, net of allowance, in the consolidated balance sheets. The Company’s involvement in the collection process for these receivables is not considered to constitute significant continuing involvement, and, therefore, the receivables are accounted for as a sale under ASC Topic 860, Transfers and Servicing. Cash collections from the sale of receivables are reflected within operating activities in the consolidated statements of cash flows. The Company is also party to arrangements with certain customers that allow for early collection of receivables for a nominal fee, at the Company’s option. Discount charges related to the above described financing arrangements, which are included within interest expense, net, totaled approximately $23.8 million, $20.7 million and $12.9 million for the years ended December 31, 2025, 2024 and 2023, respectively.

(a) The term loan was terminated and fully repaid as of the second quarter of 2025, pursuant to the terms of the amended and restated senior unsecured credit facility, as described below.
Senior Credit Facility
On June 26, 2025, the Company entered into an amended and restated five-year , senior unsecured credit facility (the “Credit Facility”) replacing the November 1, 2021 senior unsecured credit facility (“Existing Credit Agreement”) that would otherwise have terminated on November 1, 2026. The amendment, among other items, maintained revolving commitments of an aggregate amount of $1.9 billion, terminated the term loan under the Existing Credit Agreement, and extended the maturity of the senior unsecured credit facility from November 1, 2026 to June 26, 2030. The amendment also eliminated certain restrictions on the ability of the Company to make distributions or repurchase capital stock, the requirement of the Company to maintain a minimum consolidated interest coverage ratio and certain other negative covenants. All other material terms and conditions of the Credit Facility were substantially unchanged. The Credit Facility allows the Company to borrow up to an aggregate equivalent amount of $300 million in revolving advances in either Canadian dollars or Mexican pesos. The maximum amount available for letters of credit under the Credit Facility is $750 million, of which up to $250 million can be denominated in either Canadian dollars or Mexican pesos. The Credit Facility also provides for swing line loans of up to $125 million, and, subject to certain conditions, the Company has the option to increase revolving commitments as defined in the Credit Facility. Borrowings under the Credit Facility will be used for working capital requirements, capital expenditures and other corporate purposes, including potential acquisitions, equity investments or other strategic arrangements, and/or the repurchase or prepayment of indebtedness, among other corporate borrowing requirements, including potential share repurchases. As of both December 31, 2025 and 2024, the fair value of the Credit Facility, as estimated based on an income approach utilizing significant unobservable Level 3 inputs including discount rate assumptions, approximated its carrying value.
79
Outstanding revolving loans under the Credit Facility bear interest, at the Company’s option, at a rate equal to either (a) Term SOFR, TIIE, or Term CORRA, in each case as defined in the Credit Facility, plus a margin of 1.125 % to 1.625 %, or (b) Base Rate, as defined below, plus a margin of 0.125 % to 0.625 %. The Base Rate equals the highest of (i) the Federal Funds Rate, as defined in the Credit Facility, plus 0.50 %, (ii) Bank of America’s prime rate, and (iii) Term SOFR plus 1.00 %. Financial standby letters of credit and commercial letters of credit issued under the Credit Facility are subject to a letter of credit fee ranging from 1.125 % to 1.625 %, and performance standby letters of credit issued under such Credit Facility are subject to a letter of credit fee ranging from 0.3125 % to 0.6875 %. The Company must also pay a commitment fee to the lenders ranging from 0.150 % to 0.225 % on any unused availability under the Credit Facility. In each of the foregoing cases, the applicable margin or fee is based on the Company’s Consolidated Leverage Ratio and Debt Rating, each as defined in the Credit Facility, as of the most recent fiscal quarter.
Revolving loans accrued interest at weighted average rates of approximately 4.56 % and 4.97 % per annum as of December 31, 2025 and 2024, respectively. Letters of credit of approximately $57.1 million and $64.3 million were issued as of December 31, 2025 and 2024, respectively. As of December 31, 2025 and 2024, letter of credit fees accrued at 0.4375 % and 0.5625 % per annum, respectively, for performance standby letters of credit, and for financial standby letters of credit, accrued at 1.250 % and 1.375 % per annum, respectively. Outstanding letters of credit mature at various dates and most have automatic renewal provisions, subject to prior notice of cancellation.
As of December 31, 2025 and 2024, availability for revolving loans totaled $1,724.9 million and $1,792.6 million, respectively, or up to $692.9 million and $585.7 million, respectively, for new letters of credit. As of December 31, 2025 and 2024, outstanding revolving borrowings denominated in foreign currencies totaled $43.0 million and $43.1 million, respectively, and accrued interest at a weighted average rate of approximately 3.81 % and 4.97 % per annum, respectively. Revolving loan borrowing capacity included $257.0 million and $256.9 million of availability in either Canadian dollars or Mexican pesos as of December 31, 2025 and 2024, respectively. The unused facility fee as of December 31, 2025 and 2024 accrued at rates of 0.175 % and 0.200 % per annum, respectively.
Other Credit Facilities. The Company has a separate credit facility, which is renewable on an annual basis, under which it may issue up to $50.0 million of performance standby letters of credit. As of December 31, 2025 and 2024, letters of credit issued under this facility totaled $33.4 million and $17.4 million, respectively, which accrued fees at 0.50 % and 0.75 % per annum, respectively. The Company’s other credit facilities are subject to customary provisions and covenants.
The Company has $600 million aggregate principal amount of senior unsecured notes due August 15, 2028, which bear interest at a rate of 4.500 % (the “4.500 % Senior Notes”), which were issued at par in a private offering. Interest on the 4.500 % Senior Notes is payable semiannually in arrears on February 15 and August 15 of each year. As of December 31, 2025 and 2024, the fair value of the Company’s 4.500 % Senior Notes totaled approximately $595.7 million and $581.9 million, respectively.
The Company has the option to redeem all or a portion of the 4.500 % Senior Notes at the redemption prices specified in the indenture that governs the 4.500 % Senior Notes (the “4.500 % Senior Notes Indenture”), plus accrued and unpaid interest, if any, to, but excluding, the redemption date. If a change of control, as defined in the 4.500 % Senior Notes Indenture, occurs, the Company must make an offer to repurchase all of the 4.500 % Senior Notes then outstanding at a price equal to 101 % of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase.
The 4.500 % Senior Notes Indenture, among other things, generally limits the ability of the Company and certain of its subsidiaries to create liens and effect mergers, subject to certain exceptions. The 4.500 % Senior Notes Indenture provides for customary events of default, subject to customary grace and cure periods. Generally, if an event of default occurs and is continuing, the trustee or holders of at least 30 % of the 4.500 % Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on all of the 4.500 % Senior Notes immediately due and payable.
On June 10, 2024, the Company completed an offering of $550 million aggregate principal amount of 5.900 % senior notes due June 15, 2029 (the “5.900 % Senior Notes”). Interest on the 5.900 % Senior Notes is payable semiannually in arrears on June 15 and December 15 of each year. The 5.900 % Senior Notes are general senior unsecured obligations of the Company, and rank equal in right of payment with all of the Company’s existing and future senior unsecured indebtedness and senior in right of payment to all of the Company’s future subordinated indebtedness. The 5.900 % Senior Notes are effectively subordinated to all secured indebtedness of the Company, to the extent of the value of the assets securing such indebtedness, and structurally subordinated to all of the obligations of the subsidiaries of the Company, including trade payables. Financing costs incurred in connection with the issuance of the 5.900 % Senior Notes totaled approximately $5.9 million and are being amortized over the term of the 5.900 % Senior Notes using the effective interest method. As of December 31, 2025 and 2024, the fair value of the Company’s 5.900 % Senior Notes totaled approximately $574.1 million and $558.8 million, respectively.
The Company has the option to redeem all or a portion of the 5.900 % Senior Notes at the redemption prices specified in the indenture that governs the 5.900 % Senior Notes (the “5.900 % Senior Notes Indenture”), plus accrued and unpaid interest, if any, to, but excluding, the redemption date. If a change of control triggering event, as defined in the 5.900 % Senior Notes Indenture, occurs, each holder of the 5.900 % Senior Notes will have the right to require the Company to repurchase all or any portion of such holder’s 5.900 % Senior Notes then outstanding at a price equal to 101 % of the principal amount of the 5.900 % Senior Notes, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase, subject to the right of holders of 5.900 % Senior Notes on the relevant record date to receive interest due on the relevant interest payment date.
The 5.900 % Senior Notes Indenture, among other things, generally limits the ability of the Company and certain of its subsidiaries to create liens, enter into sale and leaseback transactions and effect mergers, subject to certain exceptions. The 5.900 % Senior Notes Indenture provides for customary events of default, which include, subject, in certain cases, to customary grace and cure periods, among others, nonpayment of principal or interest; breach of other covenants or agreements in the 5.900 % Senior Notes Indenture; failure to pay certain other indebtedness; and certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing, the trustee or holders of at least 25 % of the 5.900 % Senior
80
Notes then outstanding may declare the principal amount, premium, if any, and accrued interest on all of the 5.900 % Senior Notes to be immediately due and payable.
The Company used a portion of the proceeds from the 5.900 % Senior Notes offering in 2024 to purchase $203.7 million in aggregate principal amount of 6.625 % IEA Senior Notes (as defined below). The remaining net proceeds, along with available cash, were used to repay the Company’s $400.0 million Three-Year Term Loan Facility. In connection with these transactions, the Company recorded a pre-tax debt extinguishment loss of approximately $11.3 million during the year ended December 31, 2024, which is separately presented within the Company’s consolidated statements of operations.
The Company has $74.9 million aggregate principal amount of 6.625 % senior unsecured notes due August 15, 2029 (the “6.625 % Senior Notes”), with a carrying value of $72.3 million and $71.6 million as of December 31, 2025 and 2024, respectively. Interest on the 6.625 % Senior Notes is payable semiannually in arrears on February 15 and August 15 of each year. The 6.625 % Senior Notes were previously composed of $225.1 million aggregate principal amount of 6.625 % IEA senior notes (the “6.625 % IEA Senior Notes”) and $74.9 million aggregate principal amount of 6.625 % MasTec senior notes (the “6.625 % MasTec Senior Notes”).
Concurrently with the Company’s 2024 offering of the 5.900 % Senior Notes, IEA Energy Services LLC (“IEA LLC”), a wholly-owned subsidiary of the Company, launched a tender offer and consent solicitation (the “IEA Tender”) for the 6.625 % IEA Senior Notes due 2029. The Company used a portion of the proceeds from the 5.900 % Senior Notes offering to purchase $203.7 million in aggregate principal amount of 6.625 % IEA Senior Notes tendered at a price equal to 100.0 % of the principal amount of the 6.625 % IEA Senior Notes, plus accrued and unpaid interest to, but excluding, the payment date. In July 2024, subsequent to the IEA Tender, IEA LLC exercised its right under the indenture that governs the 6.625 % IEA Senior Notes to redeem the remaining $21.4 million in aggregate principal amount of the 6.625 % IEA Senior Notes at a price equal to 95.0 % of the principal amount of the 6.625 % IEA Senior Notes redeemed, which amount approximated their carrying value, plus accrued and unpaid interest to, but excluding, the redemption date. As of both December 31, 2025 and 2024, the fair value of the Company’s 6.625 % Senior Notes approximated their carrying value.
The 6.625 % Senior Notes are general senior unsecured obligations of the Company, and rank equal in right of payment with all of the Company’s existing and future senior unsecured indebtedness and senior in right of payment to any of the Company’s future subordinated indebtedness. The 6.625 % Senior Notes are effectively subordinated to all secured indebtedness of the Company to the extent of the value of the assets securing such indebtedness and are structurally subordinated to all obligations of the subsidiaries of the Company, including trade payables.
The 6.625 % Senior Notes Indenture provides for customary events of default, which include, subject, in certain cases, to customary grace and cure periods, among others, nonpayment of principal or interest; breach of other covenants or agreements in the 6.625 % Senior Notes Indenture; failure to pay certain other indebtedness; and certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing, the trustee or holders of at least 30 % of the 6.625 % Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on all of the 6.625 % Senior Notes immediately due and payable.
If a Change of Control, as defined in the 6.625 % Senior Notes Indenture, occurs, the Company must make an offer to repurchase all of the 6.625 % Senior Notes, then outstanding at a price equal to 101 % of their principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.
2025 Term Loan Facility
On June 26, 2025, the Company entered into a new $600 million senior unsecured term loan agreement (the “2025 Term Loan Facility”). The 2025 Term Loan Facility will mature on June 26, 2028, and the loans thereunder are not subject to amortization and are not guaranteed or secured by any assets of the Company or any of its subsidiaries. As of December 31, 2025, the Company had $600 million outstanding under the 2025 Term Loan Facility. The fair value of the 2025 Term Loan Facility as of December 31, 2025, as estimated based on an income approach utilizing significant unobservable Level 3 inputs including discount rate assumptions, approximated its carrying value. Using the net proceeds from the 2025 Term Loan Facility, together with available cash, the Company repaid the $328.1 million term loan under the Existing Credit Agreement and the remaining $277.5 million of the Company’s unsecured five-year term loan (the “Five-Year Term Loan”) that would otherwise have matured on October 7, 2027.
Outstanding loans under the 2025 Term Loan Facility bear interest, at the Company’s option, at a rate equal to either (a) Term SOFR, as defined in the 2025 Term Loan Facility, plus a margin of 1.00 % to 1.50 %, or (b) a Base Rate, as defined below, plus a margin of up to 0.50 %. The Base Rate equals the highest of (i) the Federal Funds Rate, as defined in the 2025 Term Loan Facility, plus 0.50 %, (ii) Bank of America’s prime rate, and (iii) Term SOFR plus 1.00 %. In each of the foregoing cases, the applicable margin is based on the Company’s Consolidated Leverage Ratio and Debt Rating, each as defined in the 2025 Term Loan Facility, as of the most recent fiscal quarter. As of December 31, 2025, the 2025 Term Loan Facility accrued interest at a rate of 4.85 %.
As described above, the Company used a portion of the net proceeds from the 2025 Term Loan Facility, together with available cash, to repay the remaining $277.5 million of the Five-Year Term Loan that would otherwise have matured on October 7, 2027.
Loss on Extinguishment of Debt
For the year ended December 31, 2024, the Company recognized a pre-tax debt extinguishment loss of approximately $11.3 million in connection with the repayment of the $203.7 million 6.625 % IEA Senior Notes and $400.0 million Three-Year Term Loan Facility, which is separately presented within the Company’s consolidated statements of operations.

Debt Covenants
The Company’s Credit Facility and 2025 Term Loan Facility contain affirmative and negative covenants that, among other things, limit the Company’s ability to engage in certain activities, including, but not limited to, acquisitions, mergers and consolidations, debt incurrence, investments, asset sales and lien incurrence. In addition, the Credit Facility and 2025 Term Loan Facility provide for customary events of default and carries cross-default provisions with the Company’s other significant debt instruments, including the Company’s indemnity agreement with its surety provider, as well as customary remedies, including the acceleration of repayment of outstanding amounts and other remedies. The Credit Facility and 2025 Term Loan Facility require the Company to maintain a maximum Consolidated Leverage Ratio, as defined in the Credit Facility and 2025 Term Loan Facility, respectively, of not more than 3.50 :1.00 as of the end of any fiscal quarter (except that, subject to certain conditions, if a permitted acquisition or series of permitted acquisitions having consideration exceeding $200 million occurs, such ratio is increased to 4.00 :1.00 for the fiscal quarter in which the acquisition is completed and the four subsequent fiscal quarters). For purposes of calculating the Consolidated Leverage Ratio, funded indebtedness excludes undrawn standby performance letters of credit included in the calculation of Consolidated Funded Indebtedness, as defined in the Credit Facility and 2025 Term Loan Facility, respectively. Additionally, the Company’s Senior Notes are subject to customary provisions and covenants, as detailed above.
MasTec was in compliance with the provisions and covenants of its outstanding debt instruments as of both December 31, 2025 and 2024.
Additional Information

Note 11 – Other Retirement Plans
Multiemployer Plans
As discussed in Note 1 - Business, Basis of Presentation and Significant Accounting Policies, certain of MasTec’s subsidiaries are party to various collective bargaining agreements with unions representing certain of their employees, which require the Company to pay specified wages, provide certain benefits to their union employees and contribute certain amounts to MEPPs. The PPA defines the funding rules for defined benefit pension plans and establishes funding classifications for U.S.-registered multiemployer pension plans. Under the PPA, plans are classified into one of five categories based on multiple factors, which categories are also referred to as a plan’s “zone status”: Green (safe), Yellow (endangered), Orange (seriously endangered), and Red (critical or critical and declining). Factors included in the determination of a plan’s zone status include: funded percentage, cash flow position and whether the plan is projecting a minimum funding deficiency.
A multiemployer plan that is so underfunded as to be in “endangered,” “seriously endangered,” “critical,” or “critical and declining” status, as determined under the PPA, is required to adopt a funding improvement plan (“FIP”) or a rehabilitation plan (“RP”), which, among other actions, could include decreased benefits and increased employer contributions, which could take the form of a surcharge on benefit contributions. These actions are intended to improve their funding status over a period of years. If a pension fund is in critical status, a participating employer must pay an automatic surcharge in addition to contributions otherwise required under the collective bargaining agreement (“CBA”). With some exceptions, the surcharge is equal to 5 % of required contributions for the initial critical year and 10 % for each succeeding plan year in which the plan remains in critical status. The surcharge ceases on the effective date of a CBA or other agreement that includes contribution and benefit terms consistent with the rehabilitation plan. Certain plans in which the Company participates are in “endangered,” “seriously endangered,” “critical,” or “critical and declining” status. The amount of additional funds, if any, that the Company could be obligated to contribute to these plans in the future cannot be estimated due to the uncertainty of the future levels of work that could be required of the union employees covered by these plans, as well as the required future contribution rates and possible surcharges applicable to these plans. See Note 15 - Commitments and Contingencies for additional information.

The number of union employees employed at a given time, and the plans in which they participate, vary depending upon the location and number of ongoing projects and the need for union resources in connection with those projects. Total contributions to multiemployer plans and the related number of employees covered by these plans for the periods indicated were as follows:

The fluctuations in the number of employees covered under multiemployer plans and associated contributions in the table above related primarily to the timing of activity for the Company’s union resource-based projects, as well as the effects of the Company’s acquisitions. For the years ended December 31, 2025, 2024 and 2023, multiemployer plan activity was driven primarily by project work within the Company’s Power Delivery and Pipeline Infrastructure operations. In 2023, multiemployer plan activity also included acquisition-related project work within the Company’s Clean Energy and Infrastructure operations.
Note 12 – Equity
Share Activity
The Company’s share repurchase program provides for the repurchase, from time to time, of MasTec common shares in open market transactions or in privately negotiated transactions in accordance with applicable securities laws. The timing and the amount of any repurchases is determined based on market conditions, legal requirements, cash flow and liquidity needs, and other factors. The Company’s share repurchase program, under which the Company undertakes share repurchases for strategic purposes, including (i) when management believes that the market price of the Company’s stock is undervalued, (ii) such repurchases will enhance long-term shareholder value, (iii) the Company has adequate liquidity, and (iv) management believes that such repurchases are appropriate uses of capital, do not have an expiration date and may be modified or suspended at any time at the Company’s discretion. Share repurchases, which are recorded at cost and are held in the Company’s treasury, are funded with available cash or with availability under the Credit Facility. The Company may use either authorized and unissued shares or treasury shares to meet share issuance requirements. Treasury stock is recorded at cost. Share repurchases are recorded as of the trade date, whereas payments for share repurchases are made on the date the trade is settled.
For the year ended December 31, 2025, the Company repurchased 0.7 million shares of its common stock for an aggregate purchase price totaling $77.3 million, which completed the Company’s $150 million March 2020 share repurchase program during the second quarter of 2025. There were no share repurchases under the Company’s share repurchase program for either of the years ended December 31, 2024 or 2023. In May 2025, the Company’s Board of Directors authorized a new $250 million share repurchase program, for which the full amount remains available for future share repurchases as of December 31, 2025.
During the fourth quarter of 2024, the Company reissued approximately 0.1 million shares of its treasury stock with a cost basis of $3.1 million in settlement of certain Additional Payments in connection with the HMG acquisition.

In assessing the ability to realize the Company’s deferred tax assets, management considers whether it is more likely than not that some portion, or all, of its deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which these temporary differences become deductible. Management considers the Company’s projected future taxable income and prudent and feasible tax planning strategies in making this assessment. The Company’s valuation allowances as of both December 31, 2025 and 2024 are related primarily to foreign and state net operating losses and deferred tax assets.
The Company’s deferred tax assets for its state net operating loss carryforwards, which may be carried forward from 5 years to indefinitely, depending on the jurisdiction, totaled approximately $25.9 million and $28.7 million as of December 31, 2025 and 2024, respectively. The Company’s deferred tax assets for its foreign net operating loss carryforwards, which are primarily related to the Company’s Canadian operations, totaled approximately $54.9 million and $56.0 million as of December 31, 2025 and 2024, respectively, and begin to expire in 2026. As of both December 31, 2025 and December 31, 2024, the Company had no
The Company is generally free of additional U.S. federal tax consequences on distributed foreign subsidiary earnings due to a dividends received deduction implemented as part of the move to a territorial tax system in connection with the Tax Cuts and Jobs Act of 2017 (“TCJA”). The Company has generally not made a provision for income taxes on unremitted foreign earnings because such earnings are insignificant and are intended to be indefinitely reinvested outside the United States. The Company expects that domestic cash resources will be sufficient to fund its domestic operations and cash commitments in the future.

The Company classifies interest, penalties and recoveries related to uncertain tax positions as a component of income tax expense in the consolidated statements of operations. For the year ended December 31, 2025, interest and penalties totaled a benefit of approximately $2.5 million and for the years ended December 31, 2024 and 2023, totaled an expense of approximately $0.7 million and $2.6 million, respectively. Accrued interest and penalties related to uncertain tax positions were $5.3 million and $7.8 million as of December 31, 2025 and 2024, respectively. The effect on the Company’s tax rate if it were to recognize its gross unrecognized tax benefits as of December 31, 2025 approximates $63.8 million, including interest and penalties. While it is possible that there could be audit settlements and/or lapses in certain statutes of limitation relating to uncertain tax positions, management has determined that it is too difficult to predict the outcome of such matters.
The IRS has examined the Company’s federal income tax returns through 2017. Certain foreign and state taxing authorities are examining various years. The final outcome of these examinations is not yet determinable. With few exceptions, as of December 31, 2025, the Company is no longer subject to state examinations by taxing authorities for years before 2020.
On July 4, 2025, new tax legislation was signed into law, known as the One Big Beautiful Bill Act (the “OBBBA”), which makes permanent many of the tax provisions enacted in 2017 as part of the TCJA that were set to expire at the end of 2025. In addition, the OBBBA makes changes to certain U.S. corporate tax provisions, but many are generally not effective until 2026. The Company incorporated the provisions of the new law in preparing its financial statements for the year ended December 31, 2025, which did not have a material impact on its effective annual tax rate.
Note 14 – Segments and Related Information
Segment Discussion
The Company manages its operations under five operating segments, which represent its five reportable segments: (1) Communications; (2) Clean Energy and Infrastructure; (3) Power Delivery; (4) Pipeline Infrastructure and (5) Other. The reportable segments comprise the structure used by the Company’s Chief Executive Officer who is determined to be the Chief Operating Decision Maker (“CODM”) to make key operating decisions and assess performance. This structure is generally focused on broad end-user markets for the Company’s labor-based construction services. All five reportable segments derive their revenue primarily from the engineering, installation and maintenance of infrastructure, primarily in North America.
The Communications segment performs engineering, construction, maintenance and customer fulfillment activities related to communications and digital infrastructure, primarily for wireless and wireline/fiber networks, data center buildout and interconnection, wireless integration and optimization and install-to-the-home services, as well as select utility infrastructure, among others. The Clean Energy and Infrastructure segment primarily serves energy, utility, government and other end-markets through the installation and construction of power generation facilities, primarily from clean energy and renewable sources, such as wind, solar, biomass, natural gas and hydrogen, as well as battery storage systems for renewable energy; various types of heavy civil and industrial infrastructure services, including roads, bridges and rail; and environmental remediation services. The Power Delivery segment primarily serves the energy, utility and data center infrastructure industries through the engineering, construction and maintenance of power transmission and distribution infrastructure, including electrical and gas lines, power reserve and battery infrastructure, and distribution network systems, substations and grid modernization; emergency restoration services following natural disasters and accidents; and environmental planning and compliance services. The Pipeline Infrastructure segment performs engineering, construction, maintenance and other services for pipeline infrastructure, including natural gas, water and carbon capture sequestration pipelines, as well as pipeline integrity, including the repair of pipeline infrastructure and facilitating their safe use throughout their lifecycle, and other services for the energy and utilities industries. The Other segment includes certain equity investees, the services of which may vary from those provided by the Company’s primary segments, as well as other small business units with activities in certain international end-markets.
In the first quarter of 2025, the Company made changes to its Communications and Power Delivery segment structures to more closely align with the segments’ end markets and to better correspond with the operational management reporting structure of both segments. These changes included moving a component with utility operations previously reported in the Communications segment to the Power Delivery segment. These changes did not impact the Company’s consolidated financial statements, but did impact its reportable segments, including historical financial information. The segment data presented below have been recast for the historical periods to reflect these segment changes.
The accounting policies of the reportable segments are the same as those described in Note 1 - Business, Basis of Presentation and Significant Accounting Policies. Intercompany revenue and costs among the reportable segments are accounted for as if the sales were to third parties because these items are based on negotiated fees between the segments involved. All intercompany transactions and balances are eliminated in consolidation. Intercompany revenue and costs between entities within a reportable segment are eliminated to arrive at segment totals.
90
Eliminations between segments are separately presented. Corporate results include amounts related to corporate and administrative functions, such as treasury, legal and other professional activities, including certain settlements; changes in the fair value of Earn-outs, other liabilities and certain investments; acquisition-related transaction costs; and other discrete items, including certain integration activities and debt transaction costs. Segment results include certain allocations of centralized costs such as general liability, medical and workers’ compensation, and auto liability insurance and certain information technology and interest costs, as well as certain discrete items, including certain acquisition and business integration and/or streamlining costs. Income tax expense, which is recorded within Corporate results, is managed on a consolidated basis and is not allocated to the reportable segments.
EBITDA is the measure of profitability used by the Company’s CODM to manage its segments and for segment reporting purposes. As appropriate, the Company supplements the reporting of its consolidated financial information determined in accordance with U.S. GAAP with certain non-U.S. GAAP financial measures, including EBITDA. The Company believes these non-U.S. GAAP measures provide meaningful information and help investors understand the Company’s financial results and assess its prospects for future performance. The Company uses EBITDA to evaluate its performance, both internally and as compared with its peers, because it excludes certain items that may not be indicative of the Company’s core operating results for its reportable segments, as well as items that can vary widely across different industries or among companies within the same industry. Segment EBITDA is used to allocate resources, such as employees, financial and capital resources, for each segment and management monitors segment results compared to prior period, forecasted results and the annual plan. Segment EBITDA is calculated in a manner consistent with consolidated EBITDA.
Summarized financial information for MasTec’s reportable segments is presented and reconciled to consolidated financial information for total MasTec in the following tables, including a reconciliation of segment EBITDA to consolidated income (loss) before income taxes, all of which are presented in millions. The tables below, which may contain slight summation differences due to rounding, reflect certain financial data for each reportable segment and have been recast as described above.

Foreign Operations. MasTec operates primarily within the United States and Canada. Revenue derived from foreign operations totaled $177.2 million, $93.3 million and $95.1 million for the years ended December 31, 2025, 2024 and 2023, respectively. Revenue from foreign operations was derived primarily from the Company’s Canadian operations in its Pipeline Infrastructure segment. Long-lived assets held by the Company’s businesses in foreign countries included property and equipment, net, of $23.0 million, $25.3 million and $17.5 million, as of December 31, 2025, 2024 and 2023, respectively, and intangible assets and goodwill, net, of $108.8 32.6 million as

of December 31, 2023. Substantially all of the Company’s long-lived and intangible assets and goodwill in foreign countries relate to its Canadian operations. As of each of December 31, 2025, 2024 and 2023, amounts due from customers from which foreign revenue was derived accounted for approximately 1
Significant Customers. For the year ended December 31, 2025, AT&T represented approximately 10 % of the Company’s total consolidated revenue. The Company’s relationship with AT&T is based upon multiple separate master service and other service agreements, including for maintenance services and construction/installation contracts for wireless and wireline, and for which the related revenue is included primarily within the Communications segment. No customer represented greater than 10% of the Company’s total consolidated revenue in either of the years ended December 31, 2024 and 2023. Revenue from governmental entities totaled approximately 13 11 % for the year ended December 31, 2023, substantially all of which was derived from its U.S. operations.
Note 15 – Commitments and Contingencies
MasTec is subject to a variety of legal cases, claims and other disputes that arise from time to time in the ordinary course of its business, including project contract price and other project disputes, other project-related liabilities and acquisition purchase price disputes. MasTec cannot provide assurance that it will be successful in recovering all or any of the potential damages it has claimed or in defending claims against the Company. The outcome of such cases, claims and disputes cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows.
Other Commitments and Contingencies
Leases. In the ordinary course of business, the Company enters into non-cancelable operating leases for certain of its facility, vehicle and equipment needs, including certain related party leases. See Note 9 - Lease Obligations and Note 16 - Related Party Transactions.
Letters of Credit. In the ordinary course of business, the Company is required to post letters of credit for its insurance carriers and surety bond providers and in support of performance under certain contracts as well as certain obligations associated with the Company’s equity investments and other strategic arrangements, including its VIEs. In addition, from time to time, certain customers require the Company to post letters of credit to ensure payment of subcontractors and vendors, and guarantee performance under contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit under certain conditions. If this were to occur, the Company would be required to reimburse the issuer of the letter of credit, which, depending upon the circumstances, could result in a charge to earnings. As of December 31, 2025 and 2024, there were $90.5 million and $81.7 million, respectively, of letters of credit issued under the Company’s credit facilities. Letter of credit claims have historically not been material. The Company is not aware of any material claims relating to its outstanding letters of credit as of December 31, 2025 or 2024.
Performance and Payment Bonds. In the ordinary course of business, MasTec is required by certain customers to provide performance and payment bonds for contractual commitments related to its projects. These bonds provide a guarantee to the customer that the Company will perform under the terms of a contract and that the Company will pay its subcontractors and vendors. If the Company fails to perform under a contract or to pay its subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for expenses or outlays it incurs. As of December 31, 2025 and 2024, outstanding performance and payment bonds approximated $10.9 billion and $7.6 billion, respectively, and estimated costs to complete projects secured by these bonds totaled $4.6 billion and $2.2 billion as of December 31, 2025 and 2024, respectively. Included in these balances as of December 31, 2025 and 2024 are $1.1 billion and $838.7 million, respectively, of outstanding performance and payment bonds issued on behalf of the Company’s proportionately consolidated non-controlled contractual joint ventures, representing the Company’s proportionate share of the total bond obligation for the related projects.
Investment and Strategic Arrangements. The Company holds undivided interests, ranging from 85 % to 90 %, in multiple proportionately consolidated non-controlled contractual joint ventures that provide infrastructure construction services for electrical transmission projects, as well as undivided interests, ranging from 25 % to 50 %, in each of nine civil construction projects. Income and/or loss incurred by these joint ventures is generally shared proportionally by the respective joint venture members, with the members of the joint ventures jointly and severally liable for all of the obligations of the joint venture. The respective joint venture agreements provide that each joint venture partner indemnify the other party for any liabilities incurred by such joint venture in excess of its ratable portion of such liabilities. Thus, it is possible that the Company could be required to pay or perform obligations in excess of its share if the other joint venture partners fail or refuse to pay or perform their respective share of the obligations. As of December 31, 2025, the Company was not aware of material future claims against it in connection with these arrangements. For the year ended December 31, 2023 the Company provided $0.5 million of project-related financing to its contractual joint ventures, which amount was outstanding as of both the years ended December 31, 2025 and 2024.
One of the Company’s subsidiaries has a subcontracting arrangement with a contractual joint venture in which it holds a 35 % undivided interest, for which the related project was completed in 2022. Outstanding performance guarantees on behalf of this contractual joint venture totaled Canadian $9.7 7.1 million and $6.7 million, respectively. The Company has other investment and strategic arrangements, under which it may incur costs or provide financing, performance, financial and/or other guarantees. See Note 4 - Fair Value of Financial Instruments and Note 16 - Related Party Transactions for additional information pertaining to the Company’s investment and strategic arrangements.
Self-Insurance. MasTec maintains insurance policies for workers’ compensation, general liability and automobile liability, which are subject to per claim deductibles. The Company is self-insured up to the amount of the deductible. The Company also maintains excess umbrella coverage. The Company manages certain of its insurance liabilities indirectly through its wholly-owned captive insurance company, which reimburses claims up to the applicable insurance limits. Captive insurance-related cash balances totaled approximately $3.3 million and $2.2 million as of December 31, 2025 and 2024, respectively, which amounts are generally not available for use in the Company’s other operations.
93
As of December 31, 2025 and 2024, MasTec’s estimated gross liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled $306.8 million and $251.0 million, respectively, of which $224.9 million and $184.1 million, respectively, were reflected within other long-term liabilities, with the remainder reflected within other accrued expenses, in the consolidated balance sheets as of the respective periods. Related insurance recoveries/receivables totaled $25.2 million and $24.4 million as of December 31, 2025 and 2024, respectively, of which $22.4 million and $21.4 million was reflected within other long-term assets, with the remainder reflected within other current assets, in the consolidated balance sheets as of the respective periods. MasTec also maintains an insurance policy with respect to employee group medical claims, which is subject to annual per employee maximum losses. MasTec’s estimated liability for employee group medical claims totaled $2.3 million and $4.7 million as of December 31, 2025 and 2024, respectively.
The Company is required to post collateral, generally in the form of letters of credit, surety bonds and cash to certain of its insurance carriers. Insurance-related letters of credit for the Company’s workers’ compensation, general liability and automobile liability policies amounted to $7.4 million and $8.7 million as of December 31, 2025 and 2024, respectively. Outstanding surety bonds related to self-insurance programs amounted to $198.6 million and $196.3 million as of December 31, 2025 and 2024, respectively.
Employment Agreements. The Company has employment agreements with certain executives and other employees, which provide for compensation and certain other benefits and for severance payments under certain circumstances. Certain employment agreements also contain clauses that become effective upon a change in control of the Company. Upon the occurrence of any of the defined events in the various employment agreements, the Company would be obligated to pay certain amounts to the related employees, which vary with the level of the employees’ respective responsibility.
Collective Bargaining Agreements and Multiemployer Plans. As discussed in Note 1 - Business, Basis of Presentation and Significant Accounting Policies and Note 11 - Other Retirement Plans, certain of MasTec’s subsidiaries are party to various collective bargaining agreements with unions representing certain of their employees, which require the Company to pay specified wages, provide certain benefits and contribute certain amounts to MEPPs. The Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980 (collectively, “ERISA”), which governs U.S.-registered MEPPs, subjects employers to substantial liabilities in the event of an employer’s complete or partial withdrawal from, or upon termination of, such plans.
The Company currently contributes, and in the past, has 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. As of December 31, 2025, the Company does not have plans to withdraw from, and is not aware of circumstances that would reasonably lead to material claims against it, in connection with the MEPPs in which it participates. There can be no assurance, however, that the Company will not be assessed liabilities in the future, including in the form of a surcharge on future benefit contributions or increased contributions on underfunded plans. The amount the Company could 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, which could be negatively affected by economic and market conditions, and the level of underfunding of such plans. In connection with the IEA acquisition in 2022, the Company assumed a multiemployer pension plan withdrawal liability, under which IEA was obligated to make monthly payments of approximately $10,000 . As of December 31, 2024, the remaining obligation approximated $1.3 million, which the Company settled in January 2025 by issuing a lump-sum payment.
Indemnities. The Company generally indemnifies its customers for the services it provides under its contracts, as well as other specified liabilities, which may subject the Company to indemnity claims, liabilities and related litigation. As of December 31, 2025 and 2024, the Company had accrued project close-out liabilities of approximately $5 million and $20 million, respectively. The Company is not aware of any other material asserted or unasserted claims in connection with its potential indemnity obligations.
Other Guarantees. From time to time in the ordinary course of its business, MasTec guarantees the obligations of its subsidiaries, including obligations under certain contracts with customers, certain lease obligations and in some states, obligations in connection with obtaining contractors’ licenses. MasTec has also issued performance and other guarantees in connection with certain of its equity investments. MasTec also generally warrants the work it performs following substantial completion of a project. Much of the work performed by the Company is evaluated for defects shortly after the work is completed. If warranty claims occur, the Company could be required to repair or replace warrantied items, or, if customers elect to repair or replace the warrantied item using the services of another provider, the Company could be required to pay for the cost of the repair or replacement. Warranty claims have historically not been material.
Concentrations of Risk. The Company is subject to certain risk factors, including, but not limited to: risks related to market conditions, market uncertainty, including from economic downturns or other economic factors, including levels of inflation and rates of interest; supply chain disruptions; governmental and/or regulatory changes, including trade policies, governmental permitting, or from climate-related matters, or other factors affecting the industries in which the Company operates; changes in customers’ capital spending plans; the Company’s ability to manage projects effectively and in accordance with management’s estimates and resolution of unapproved change orders; risks related to the Company’s acquisitions, including acquisition integration and financing; availability of qualified employees; risks related to rapid technological changes or customer consolidation; competition; the nature of the Company’s contracts, which do not obligate its customers to undertake any infrastructure projects and may be canceled on short notice; customer disputes related to the performance of services; exposure to litigation; seasonality, adverse weather conditions and fluctuations in operational factors; potential exposure to environmental liabilities; exposure from system or information technology interruptions; recoverability of goodwill; collectibility of receivables; the adequacy of the Company’s reserves; public health matters; exposure related to strategic investments or foreign operations; and exposure to multiemployer pension plan liabilities. The Company grants credit, generally without collateral, to its customers. Consequently, the Company is subject to potential credit risk related to changes in business and economic factors, including from current economic uncertainty. However, MasTec generally has certain lien rights on that work and maintains a diverse customer base. The Company believes its billing and collection policies are adequate to minimize potential credit risk. MasTec’s customers include: wireless and wireline/fiber service providers; broadband operators; install-to-the-home service providers; public and private energy providers, including renewable and other energy providers; pipeline operators; civil, transportation and industrial infrastructure providers; and
94

Item 9A. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this Form 10-K, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within time periods specified in the SEC’s rules and forms.
Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.
Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2025.
Management’s Report on Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and effected by the Company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;
(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and
(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Management’s assessment of the effectiveness of internal control over financial reporting did not include the internal control over financial reporting of four entities we acquired in 2025, related to a July and a November acquisition in our Communications segment, an August acquisition in our Pipeline Infrastructure segment, and a December acquisition in our Clean Energy and Infrastructure segment. These acquisitions are included in the 2025 consolidated financial statements in this Form 10-K. Collectively, these four acquisitions’ total assets constituted approximately 2% of the Company’s total assets as of December 31, 2025 and less than 1% of the Company’s revenue for the year then ended.
Management, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our internal control over financial reporting as of the end of the period covered by this report. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in “Internal Control-Integrated Framework” (2013). Based on this assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2025.
PricewaterhouseCoopers LLP, an independent registered public accounting firm, has audited our internal control over financial reporting as of December 31, 2025 and has expressed an unqualified opinion thereon, as stated in their report that is included in Item 8.
Changes in Internal Control Over Financial Reporting. There have been no changes in the Company’s internal control over financial reporting during the fourth quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
