DEAR SHAREHOLDERS: We had another tremendous year in 2025. We achieved a number of new company records, including annual revenues, operating income, operating margin, and diluted earnings per share. We did this while maintaining

our record of excellent cash conversion. Our success demonstrates our ability to execute with discipline across EMCOR as we drive innovation and efficiency to achieve exceptional outcomes for our customers and shareholders.

2025 STRATEGIC ACHIEVEMENTS AND MILESTONES

2025 was a year of several major achievements and milestones for EMCOR. We acquired

Miller Electric Company, which is the largest acquisition in our history. The integration is on track, our leadership and values are aligned, and Miller will serve as a great platform for growth in the Southeast and Texas. In addition to Miller, we acquired nine other companies across our Mechanical Construction and Building Services segments to better serve our customers. We divested our U.K. business to focus on our U.S. operations, finding a great strategic home for the business and achieving a good result for our shareholders.

We repurchased almost $600 million in shares and announced an increase of our quarterly dividend to $0.40 per share. The active management of our business portfolio coupled with this return of cash to our shareholders

demonstrate our commitment to our successful, balanced capital allocation strategy. We continue to maintain a liquid balance sheet that serves as a foundation of strength for us and is valued by our customers, especially in key market sectors such as network and communications (including data centers), manufacturing and industrial, and high-tech manufacturing. This balance sheet also provides strategic flexibility for growth.

Further, we earned inclusion in the S&P 500, a landmark achievement. We were also recognized by Fortune as the Number 1 Most Admired Company in the Engineering and Construction Industry.

And as important as any metric, we maintained our industry-leading safety record in this demanding and complex environment with a TRIR under 1.0 for the second year in a row.

EMCOR GROUP, INC. 2025 ANNUAL REPORT

SEGMENT PERFORMANCE HIGHLIGHTS

Our operating segments performed well in 2025. We earned full-year Mechanical and Electrical Construction operating margins of 12.8% and 12.1%, respectively, demonstrating excellent execution across a diverse range of projects by size, end market, and geography. We did this while growing the revenues of these segments by 10.1% and 51.8%, respectively. We achieved a 6.0% operating margin in our Building Services segment, driven by the underlying strength of our Mechanical Services business, which achieved high single-digit operating margins and 6.0% growth, virtually all of which

was organic. Demand for this business remains strong with a primary focus on aftermarket projects and retrofits, HVAC service and repair, building automation and controls upgrades and services, and indoor air quality and energy efficiency projects. We remain well-positioned within our Industrial Services segment to serve a rebounding oil and gas industry.

Despite our record revenues, we built our RPOs (Remaining Performance Obligations) to $13.25 billion at the end of 2025, a 31.2% increase from

$10.10 billion at December of 2024. These RPOs remain diverse across many resilient sectors of the economy, such as network and communications

(including data centers), manufacturing and industrial, institutional, healthcare, and water and wastewater.

As we move into 2026, we have continued to leverage our training, VDC, pre-fabrication, and project planning and delivery capabilities. We will face macroeconomic challenges and headwinds, but, with our team's experience, we are confident in our ability to overcome them as we have before. We are committed to executing a balanced capital allocation strategy focused on organic investment, strategic acquisitions, and returning cash to shareholders through share repurchases and dividends.

With a healthy dose of humility, Fortune is right -

we are the #1 Most Admired Company in our industry, and this is because of our people. We care about each other, execute with discipline and integrity, and deliver results for our customers and shareholders. I appreciate all that my teammates do for EMCOR every day.

Thank you for your continued support as we enter

2026 with confidence and optimism.

Overview

We are one of the largest specialty contractors in the United States and a leading provider of electrical and mechanical construction and facilities services, building services, and industrial services. In 2025, we had revenues of $16.99 billion. Our services are provided to a broad range of commercial, technology, manufacturing, industrial, healthcare, utility, and institutional customers through approximately 100 operating subsidiaries, which specialize principally in providing construction services relating to electrical and mechanical systems in all types of facilities and in providing various services relating to the operation, maintenance, and management of those facilities. Such operating subsidiaries are organized into the following reportable segments:

United States electrical construction and facilities services;

United States mechanical construction and facilities services;

United States building services; and

United States industrial services.

On December 1, 2025, we sold our United Kingdom operations, the results of which are reported within our United Kingdom building services segment through the date of sale.

Our operating subsidiaries offer comprehensive and diverse solutions on a broad scale and have many long-standing customer relationships. We provide construction services and building services directly to corporations, municipalities and federal and state governmental entities, owners/developers, and tenants of buildings. We also provide our construction services indirectly by acting as a subcontractor to general contractors, systems suppliers, construction managers, developers, property managers, and other subcontractors. We generally provide industrial services directly to refineries and petrochemical plants.

We derive revenues from many different customers in numerous industries, which have operations in several different geographical areas. Of our 2025 revenues, approximately 97% were generated in the United States and approximately 3% were generated in the United Kingdom. In 2025, we derived approximately 72% of our revenues from our construction operations, approximately 21% of our revenues from our building services operations, and approximately 7% of our revenues from our industrial services operations. For additional information regarding our revenues, see Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data.

We believe that our range of service offerings, technical capability, skilled workforce, and strong project execution, along with our safety culture and financial resources, differentiate us from our competition and position us to benefit from future capital and maintenance spending by our existing and potential customers. Our strategies of expanding our portfolio of service offerings and increasing or enhancing our presence in core end markets and geographies, along with our commitment to industry-leading best practices and technological and training capabilities, place us in the position to capitalize on opportunities and trends in the industries we serve and continue to grow our business.

Increasingly, our services are focused on delivering sustainable energy solutions, enhancements in energy efficiency, reductions in waste and emissions, and improvements in the safety and comfort of our customers' facilities.

The broad scope of our operations is more particularly described below. For detailed segment financial information refer to Note 18 - Segment Information of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data.

Our executive offices are located at 301 Merritt Seven, Norwalk, Connecticut 06851-1092, and our telephone number at those offices is (203) 849-7800.

Operations

Electrical and mechanical construction and facilities services operations:

Our electrical and mechanical construction services primarily involve the design, integration, installation, start-up, operation and maintenance, and provision of services relating to:

Systems for electrical power transmission, distribution, and generation, including power cables, conduits, distribution panels, transformers, generators, uninterruptible power supply systems, and related switch gear and controls;

Premises electrical and lighting systems, including fixtures and controls;

Process instrumentation in the refining, chemical processing, and food processing industries;

Low-voltage systems, such as fire alarm, security, and process control systems;

Voice and data communications, including fiber optic and low voltage cabling, distributed antenna systems, audiovisual systems, and wireless access points;

Sustainable energy solutions such as solar, photovoltaic, and wind, as well as the installation of electric vehicle charging stations;

Roadway and transit lighting and signaling and fiber optic lines;

Computerized traffic control systems, and signal and communication equipment for mass transit systems;

Heating, ventilation, air conditioning, and refrigeration, including both traditional mechanical systems as well as geothermal solutions;

Clean-room process ventilation systems;

Fire protection and suppression systems;

Plumbing, process and high-purity piping systems;

Controls and filtration systems;

Water and wastewater treatment systems;

Central plant heating and cooling systems, including manufacturing and installing sheet metal air handling systems;

Millwright services; and

Steel fabrication, erection, and welding services.

The electrical and mechanical construction services industry has experienced growth principally due to the increased content, complexity, and sophistication of electrical and mechanical systems resulting, in part, from growth in digital processing, cloud computing, data storage, and the emergence of artificial intelligence ("AI"). In addition, facilities of all types require extensive electrical distribution systems, sophisticated power supplies, networks of low-voltage and fiber-optic communications cabling, and various mechanical, plumbing, and fire protection and suppression systems. Moreover, the need for substantial environmental controls within a building, due to the heightened need to maintain extensive servers at optimal temperatures, and the demand for increased energy efficiency, have continued to expand opportunities for our electrical and mechanical services businesses. The demand for these services is typically driven by non-residential construction and renovation activity and, in recent years, has benefited from the expansion of data centers to power AI and cloud computing, the re-shoring of the supply chain, the need for additional high-tech manufacturing facilities, and the energy transition/expansion throughout the United States.

Our electrical and mechanical construction services generally fall into one of three categories: (a) large installation projects, with contracts often in the multi-million dollar range, that involve: (i) the construction of manufacturing facilities, data centers, warehousing and distribution facilities, hospitals, and commercial buildings, (ii) institutional, public works, and infrastructure projects, or (iii) the fit-out of large blocks of space within commercial or mixed-use buildings, (b) large and medium sized capital and maintenance projects for commercial, manufacturing, pharmaceutical, healthcare, oil and gas, and industrial clients, and (c) smaller installation projects, of a short duration, typically involving fit-out, renovation, and retrofit work.

Our United States electrical and mechanical construction operations accounted for approximately 72% of our 2025 total revenues. Of such revenues, approximately 42% were generated by our electrical construction operations and approximately 58% were generated by our mechanical construction operations.

Our largest projects include those within: (a) the network and communications market sector (including data centers, data and fiber projects, and cabling); (b) the high-tech manufacturing market sector (including semiconductor, biotech, life-sciences, and pharmaceutical facilities, as well as projects across the electric vehicle value chain); (c) the manufacturing and industrial market sector (including food processing and traditional automotive manufacturing facilities, steel, pulp and paper mills, power generation (including sustainable energy solutions such as solar and wind), oil and gas refineries, and chemical processing plants); (d) the commercial market sector (including warehousing and distribution facilities and office or mixed-use buildings);

the healthcare market sector (including hospitals, surgical centers, rehabilitation and nursing facilities, and medical offices);

the institutional market sector (including educational and correctional facilities and research laboratories); (g) the water and wastewater market sector; (h) the transportation market sector (including highways, bridges, airports, and transit systems); and

(i) the hospitality and entertainment market sector (including resorts, hotels, gaming facilities, convention centers, and sports arenas and stadiums). Our largest projects, which typically range in size from $10 million up to and occasionally exceeding

$200 million, represented approximately 58% of our electrical and mechanical construction services revenues in 2025. These projects often involve new construction and a combination of design, installation, and start-up services. Depending on the size and complexity of these projects, they may span multiple years and typically require significant technical and management skills and the financial strength to obtain performance bonds, which are often a condition to bidding for and winning these projects.

Our projects of less than $10 million accounted for approximately 42% of our electrical and mechanical construction services revenues in 2025. These projects are typically completed in less than one year. They usually involve electrical and mechanical construction services when an end-user or owner undertakes construction or modification of a facility to accommodate a specific use, upgrade or replace aging systems, or increase energy efficiency. These projects frequently require electrical and mechanical systems to meet special needs such as critical systems power supply, fire protection systems, special environmental controls and high-purity air systems, sophisticated electrical and mechanical systems for data centers, new production lines in manufacturing plants, and office arrangements in existing office buildings. They are not usually dependent upon the new construction market. Demand for these projects and types of services is often prompted by the expiration of leases, changes in technology, the demand for more energy efficient systems, or changes in the customer's plant or office layout in the normal course of a customer's business.

Building services operations:

Our building services include:

Maintenance and services for mechanical, electrical, plumbing, fire safety, and building automation systems;

HVAC projects, including installation, modification and retrofits;

Program development, management, and maintenance for energy systems, including LEED and other sustainable solutions to assist our customers in reducing energy consumption;

Energy efficiency retrofit services, including HVAC, lighting, water, weatherization, and air flow management solutions;

Technical consulting and diagnostic services;

Services aimed at improving indoor air quality;

Installation and support for building systems;

Commercial and government site-based operations and maintenance;

Facility management, maintenance, and services;

Floor care and janitorial services;

Landscaping, lot sweeping, and snow removal;

Vendor management and call center services; and

Infrastructure and building projects for federal, state, and local governmental agencies.

Our building services operations have built upon our traditional electrical and mechanical construction operations and our client relationships to expand the scope of services being offered and to develop packages of services for customers on a local, regional, and national basis.

Our building services operations, which generated approximately 21% of our 2025 total revenues, provide services to owners, operators, tenants, and managers of all types of facilities. Of our building services revenues for 2025, approximately 87% were generated in the United States and approximately 13% were generated in the United Kingdom. As noted above, in December 2025, we sold our operations in the United Kingdom.

Of the building services revenues generated in the United States during 2025, approximately 77% was generated from our mechanical services division, approximately 18% was generated from our commercial site-based services division, and approximately 5% was generated from our government site-based services division. Our mechanical services division has benefited, in recent years, from increased demand for HVAC project and retrofit work, greater service repair and maintenance volumes, and the expansion of our building automation and controls solutions.

Demand for our building services is often driven by customers' decisions to focus on their core competencies, customers' programs to reduce costs, the increasing technical complexity of customers' facilities, including their mechanical, electrical, building automation, voice and data, and other systems, and the need for increased reliability, energy efficiency, and air filtration and sanitization. These trends have led to outsourcing and privatization programs whereby customers in both the private and public sectors seek to contract out those activities that support, but are not directly associated with, the customer's core business. Clients of our building services business include major corporations engaged in information technology, telecommunications, pharmaceuticals, financial services, and manufacturing, institutional organizations, healthcare providers, large retailers and other businesses with geographically dispersed locations, as well as federal and state governments.

Within our government site-based services division, we provide building services at a number of prominent buildings in the United States, including those that house the National Archives and Records Administration, the Federal Deposit Insurance Corporation, the Government Accountability Office, and the Departments of Transportation, Education, Health and Human Services, Energy, and Homeland Security, as well as other government facilities. We also provide building services, as a prime contractor or a subcontractor, to U.S. government and intelligence agencies. The agreements pursuant to which this division provides services to the federal government are frequently for a base period and a number of option years exercisable at the sole discretion of the government, are often subject to modification or renegotiation by the government in terms of scope of services, and are subject to termination for convenience by the government prior to the expiration of the applicable term.

Industrial services operations:

Our industrial services are primarily provided to customers within the oil, gas, and petrochemical industries and consist of:

Refinery turnaround planning and engineering services;

Specialty welding services;

Overhaul and maintenance of critical process units in refineries and petrochemical plants;

Specialty technical services for refineries and petrochemical plants;

Instrumentation, controls, and electrical services for energy infrastructure;

Electrical panel design, fabrication, and installation;

On-site repairs, maintenance, and service of heat exchangers, towers, vessels, and piping;

Design, manufacturing, repair, and hydro blast cleaning of shell and tube heat exchangers and related equipment; and

Renewable energy services, including large scale solar projects, energy storage, and waste to biogas solutions.

Our industrial services business, which generated approximately 7% of our 2025 total revenues, is a recognized leader in the refinery turnaround market and has a presence in the petrochemical and upstream markets. Demand for these services is highly dependent on the strength of the oil and gas and related industrial markets. Our industrial services operations perform turnaround and maintenance services for critical units of refineries and petrochemical plants to upgrade, repair, and maintain them. Such services include: (a) engineering and planning in advance of complex refinery and petrochemical turnarounds; (b) overhaul and maintenance of critical process units (including hydrofluoric alkylation units, fluid catalytic cracking units, coking units, heaters, heat exchangers, and related mechanical equipment) during refinery and petrochemical plant shut downs; (c) replacement and new construction capital projects for refineries and petrochemical plants; (d) instrumentation, controls, and electrical services for energy infrastructure; and (e) other related specialty services such as: (i) welding (including pipe welding) and fabrication; (ii) heater, boiler, and reformer repairs and replacements; converter repair and revamps; and vessel, exchanger and tower services; (iii) tower and column repairs in refineries and petrochemical plants; (iv) installation and repair of refractory materials for critical units in process plants to protect equipment from corrosion, erosion, and extreme temperatures; and (v) acid-proofing services to protect critical components at refineries from chemical exposure. These businesses also design and manufacture highly engineered shell and tube heat exchangers and provide maintenance, repair, and cleaning services for heat exchangers both in the field and at our own shops, including tube and shell repairs, bundle repairs, and extraction services.

In addition to these traditional industrial services, we are leveraging our expertise in industrial services to construct and maintain carbon capture technologies and renewable energy projects.

Due to our technical capabilities, skilled workforce, and safety record, we believe that we are in a strong competitive position in the industrial services markets that we serve. Although the technical expertise and capital investment that is required in manufacturing heat exchangers may be considered a barrier to entry in this field, there are significantly fewer barriers to entry as it pertains to turnaround projects and services.

At December 31, 2025, we employed approximately 44,000 people, all of whom were located within the United States.

Based on the most recent information available from our latest filing with the U.S. Equal Employment Opportunity Commission, the gender demographic of our employees was 90% male and 10% female. Additionally, based on such information, our employees had the following race and ethnicity demographics:

Approximately 62% of our employees are represented by various unions pursuant to approximately 450 collective bargaining agreements between our individual subsidiaries or trade associations and local unions, as well as two collective bargaining agreements that are national or regional in scope. We believe that our relations with our labor unions are generally positive.

Our ability to execute complex projects for our customers, and to perform all of our services with the excellence that makes us an industry leader, depends on our success in attracting and retaining skilled labor in a competitive market. We therefore strive to be and remain an employer of choice for the most talented employees in each of the industries and markets in which we operate. This begins with offering competitive employee compensation and benefits packages, specifically designed to meet the unique needs of each individual in our organization, which include:

Health and Welfare Plans: All full-time employees who do not participate in union plans are offered a range of choices among medical, dental and vision plans, life, accident, dependent and disability insurance, and pre-tax health savings accounts that include employer contributions.

Retirement Savings: We help provide our employees with financial security by offering a 401(k) Savings Plan, which includes company matching contributions.

Degree Assistance: Eligible employees may apply for reimbursement for job-related courses or courses taken as part of a curriculum for a business or job-related degree at an accredited institution.

Employee Assistance Program: Through our Employee Assistance Program, we offer our employees, and their dependents or household members, access to services and counseling on a variety of personal, professional, legal, and financial matters, at no cost.

College Coaching: Our College Coach Program provided through Bright Horizons provides employees and their families with support as they navigate the college admissions process, including live webinars, tuition payment financial planning, and insight from former admissions officers, finance professionals, and educators.

Key to our attraction and retention of employees is our commitment to our EMCOR Values and our focus on employee safety and inclusion. Our Board of Directors and senior leadership engage in direct oversight and management, respectively, of our significant human capital initiatives. Our Board of Directors is regularly briefed and provides input on key human capital initiatives and metrics.

Commitment to Core Values

We are committed to our EMCOR Values of Mission First: Integrity, Discipline, and Transparency and People Always: Mutual Respect and Trust, Commitment to Safety, and Teamwork. We consistently strive to ensure these values are reflected in how we do business every day, from our corporate culture and "tone at the top," established by our Board of Directors and management team, to the critical work performed by all of our people at every level throughout our organization. We reinforce our EMCOR Values through many ongoing initiatives. Our EMCOR Values are embodied in our policies and procedures, including our Code of Business Ethics and Conduct. We also regularly provide training on these values, both at time of hire and on an ongoing, periodic basis. In addition, to develop and reinforce our values company-wide, and empower our leaders to perform at the highest levels, senior leaders are invited to our Leadership for Results course at the Georgia Tech Scheller College of Business and our Leading with Character program at the Thayer Leadership Development Group at West Point. In addition, identified front line supervisors such as project managers and superintendents are invited to our Leader Development Program, which focuses on the development of skills to enhance their growth as leaders and emphasizes the importance of our EMCOR Values.

Workplace Safety

We believe that our focus on employee safety and well-being is reflected in our results. During a year in which our people worked nearly 100 million hours, the Company's Total Recordable Incident Rate in 2025 was just under 1.0, which was approximately 60% lower than the U.S. Bureau of Labor Statistics' most recently available industry average of 2.4 for NAICS Code 2382, Building Equipment Contractors. This represents our seventeenth consecutive year with a Total Recordable Incident Rate which was less than half the industry average. Our position as an industry leader in safety begins with a strong culture of care and vigilance embodied in our EMCOR Values and is supported by a comprehensive suite of training, resources, and analytics. These include: (a) our signature Be There for Life! Zero Injuries Program and Be Vigilant! Campaign, (b) incident and injury prevention planning, including in-person and online training tools and best practice guides available through our company intranet as well as to all field employees through their mobile devices, (c) enterprise level reporting and analysis of leading and lagging indicators, (d) a 24-hour incident reporting hotline, and (e) a company-wide program to share and champion best safety practices across our range of businesses. These tools have evolved with the way our people work.

Mutual Respect and Trust

In our workplace, we seek to foster a welcoming environment that reflects our EMCOR Values, including Mutual Respect and Trust. We believe that a workforce, executive management team, and Board of Directors representing a broad array of experience, perspectives, backgrounds, and personal characteristics, are important to our future success.

We strive to help all our employees realize their full potential with an equal opportunity to succeed. We work to unlock the full potential of all employees at every level through: (a) the EMCOR Manager Certificate Program, which promotes supervisory management skills, (b) our Degree Assistance Program, which provides tuition reimbursement for continuing education, and (c) the resources available to all employees on our online learning platform, EMCOR University Online, which includes thousands of on-demand training courses on a wide range of topics.

ITEM 1A. RISK FACTORS

Our business is subject to a variety of risks, including the risks described below as well as adverse business and market conditions and risks associated with our operations. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not known to us or not described below, which we have not determined to be material, may also impair our business operations. You should carefully consider the risks described below, together with all other information in this report, including information contained in the "Business," "Management's Discussion and Analysis of Financial Condition and Results of Operations," and "Quantitative and Qualitative Disclosures about Market Risk" sections. If any of the following risks actually occur, our business, financial position, results of operations, and/or cash flows could be adversely affected, and we may not be able to achieve our goals. Such events may cause actual results to differ materially from expected and historical results, and the trading price of our common stock could decline.

Economic and Strategic Risk Factors

Economic downturns, recessions, or periods of slow growth have historically led to reductions in demand for our services. Negative conditions in the credit markets, including elevated interest rates, may adversely impact our results of operations and our ability to operate our business. The level of demand from our clients for our services has been, in the past, adversely impacted by slowdowns in the industries we service, as well as in the economy in general. When the general level of economic activity has declined from historical levels, certain of our ultimate customers have delayed or canceled projects or capital spending, especially with respect to more profitable private sector work, and such slowdowns adversely affect our ability to grow, reducing our revenues and profitability. A number of economic factors, including financing conditions, the prices of commodities, and energy prices have, in the past, adversely affected the industries we serve and our ultimate customers' ability or willingness to fund expenditures. General concerns about the fundamental soundness of domestic and foreign economies may also cause ultimate customers to defer projects even if they have credit available to them. A prolonged stagnation or weakening in financial and macroeconomic conditions, potentially including higher interest rates, supply chain challenges, inflation, or geopolitical impacts, could therefore have a significant adverse effect on our revenues and profitability.

We are exposed to market risk for changes in interest rates for any borrowings under our revolving credit facility, which bear interest at variable rates. Although the Federal Reserve Board lowered the federal funds rate in 2024 and 2025, the pace and extent of additional decreases are uncertain. Increases in benchmark interest rates impact our interest expense and cost of capital, which may adversely impact our ability to make payments on future outstanding debt, raise funds through the issuance of debt, fund capital expenditures or meet other liquidity needs. Any of these impacts may adversely affect our liquidity, results of operations, and financial position. For further information on our credit facility and associated borrowing rates, refer to Note 9 - Debt of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data.

Many of our clients depend on the availability of credit to help finance their capital and maintenance projects. At times, tightened availability of credit or increased interest rates have negatively impacted the ability of existing and prospective ultimate customers to fund projects we might otherwise perform, particularly those in the more profitable private sector. As a result, our ultimate customers may defer such projects for an unknown, and perhaps lengthy, period. Any such deferrals would inhibit our growth and would adversely affect our results of operations.

In a weak economic environment, particularly in a period of restrictive credit markets, we may experience greater difficulties in collecting payments from, and negotiating change orders and/or claims with, our clients due to, among other reasons, a diminution in our ultimate customers' access to the credit markets or potential bankruptcies. If clients delay in paying or fail to pay a significant amount of our outstanding receivables, or we fail to successfully negotiate a significant portion of our change orders and/or claims with clients, it could have an adverse effect on our liquidity, results of operations, and financial position.

Our business has traditionally lagged recoveries in the general economy and, therefore, after an economic downtown we may not recover as quickly as the economy at large.

Certain of our businesses, including those within our United States industrial services segment, are exposed to risks associated with the oil and gas industry. These risks, which are not subject to our control, include volatility in the price and production of crude oil, the development of and consumer demand for alternative energy sources, including as a result of a change in consumer preference, or in an effort to reduce greenhouse gas emissions or combat climate change, and legislative and regulatory actions. In addition, macroeconomic conditions, influenced by a variety of events and circumstances, can also affect customer demand for our services within these businesses and lower prices and production volumes, or perceived risk thereof, typically results in the curtailment or deferral of spending by our customers. While higher prices for our customers' products may increase demand for our services, significant increases in the price or demand for crude oil may also result in the short-term curtailment or deferral of spending by our customers, as facility downtime to perform certain of the services we provide comes at a higher opportunity cost. Volatility within these markets, including the impact of geopolitical instability (such as disruption of shipping lanes or armed conflict or instability in oil-producing nations, including Iran and Venezuela), could negatively impact our financial position, results of operations, and cash flows.

Our business is vulnerable to the cyclical nature of the sectors in which our clients operate and is dependent upon the timing and funding of new awards. We provide construction and maintenance services to ultimate customers operating in a number of sectors which have been, and we expect will continue to be, cyclical and subject to significant fluctuations due to a variety of factors beyond our control, including economic conditions, consumer demand, technology advancements, and changes in client spending. For example, capital spending on data center infrastructure to support cloud storage and artificial intelligence ("AI") is rapidly expanding, which has increased demand for our services in recent years. If such spending were to decrease, demand for our services could decline as we transition our resources to other sectors. Regardless of economic or market conditions, investment decisions by our ultimate customers may vary by location or as a result of other factors like the availability of labor, relative construction costs, or competitive conditions in their industries. Because we are dependent on the timing and funding of new awards, we are therefore vulnerable to changes in our clients' markets and investment decisions.

Our business may be adversely affected by significant reductions in government spending, delays or disruptions in the government appropriations process or the failure to fully fund or implement legislation such as the CHIPS and Science Act of 2022 and the Inflation Reduction Act. Some of our businesses derive a portion of their revenues from governmental agencies. As a result, reduced or delayed spending by the federal government and/or state and local governments, potentially including the reduction or elimination of funding for projects or other benefits under relevant legislation, may have a material and adverse impact on our business, financial condition, results of operations, and cash flows. Significant reductions in spending aimed at reducing federal, state, or local budget deficits, the absence of a bipartisan agreement on the federal government's budget or raising the debt ceiling (and any disruption caused by a federal government shutdown as a result thereof), personnel reductions, elimination of government agencies or programs, the closure of government facilities and offices, the freezing or sequestration by the executive branch of congressionally-appropriated funds, or other changes in budget priorities could result in the deferral, delay, disruption, or cancellation of projects or contracts that we might otherwise have sought to perform. These potential events could impact the level of demand for our services and our ability to execute, complete, and receive compensation for our current contracts, or bid for and enter into new contracts with governmental agencies.

Volatility in the prices or availability of certain materials, equipment, and commodities used in our businesses and those of our customers, including as a result of inflation, supply chain disruptions, geopolitical instability, and protectionist trade measures, could adversely affect our businesses. We are exposed to market risk of increases in certain commodity prices of materials, such as copper and steel, which are used as components of supplies or materials utilized in our operations. We are also exposed to increases in energy prices, particularly as they relate to gasoline prices for our fleet of approximately 14,400 vehicles. While we believe we can increase our prices to adjust for some price increases in commodities, there can be no assurance that price increases of commodities, if they were to occur, would be recoverable. Further, the timing of our price increases may lag the timing of the underlying increases in commodity or material prices and certain of our contracts do not allow us to adjust our prices. As a result, increases in material or fuel costs could reduce our profitability with respect to projects in progress. Additionally, we rely on third-party vendors and manufacturers to supply much of the materials and equipment necessary for our operations. Disruptions, shortages, or delays in the availability of such materials and equipment have had and may have adverse impacts on our results of operations, cash flows, and reputation with our customers. For example, in recent years, we experienced supply chain delays, including long lead times for certain materials and equipment, as well as an escalation in material and fuel prices, to varying degrees. Fluctuations in the price of energy and commodity materials, whether resulting from fluctuations in market supply or demand, geopolitical conditions (including supply chain

disruptions, sanctions on Russian exports as a result of Russia's invasion of Ukraine, armed conflict between Israel and Iran or between the United States and Iran or Venezuela, and shipping lane disruptions following maritime attacks in the Gulf of Aden and the Red Sea), an increase in trade protection measures such as tariffs, or the disruption, modification, or cancellation of multilateral trade agreements, may adversely affect our customers and as a result cause them to curtail the use of our services.

On the other hand, because certain of our construction and service offerings are designed to improve energy efficiency in our clients' operations, or to assist in the generation of new sources of renewable energy, such as wind, solar, and geothermal generation, decreases in the costs of traditional energy sources such as electricity, oil, and natural gas, including as a result of recessionary pressure and reduced demand, may lower our customers' demand for efficiency improvements and alternative energy sources, which could have an adverse effect on our financial position, results of operations, and cash flows. At the same time, the availability or price of electricity may adversely impact the buildout of certain of our customers' projects, including data centers, which could adversely impact our business, financial position, and results of operations.

Changes in U.S. foreign trade policies could lead to the imposition of additional trade barriers and tariffs. We cannot predict the full extent of new, extended, or changed trade policies, including tariffs, that may be made by the current or a future presidential administration or Congress, including whether existing tariff policies will be maintained or modified or if changes in the U.S. trade policy could result in reactions from U.S. trading partners, such as adopting responsive trade policies making it more difficult or costly for us to purchase materials or supplies. Judicial review of certain trade policies and the potential consequences of court decisions on challenges to such policies, including tariffs imposed by executive order, could result in

additional changes to, or reversal of, such trade policies and practices. Changes in U.S. trade policy or in laws and policies governing foreign trade, and any resulting negative sentiments towards the United States as a result of such changes, could have an adverse impact on our business, financial position, results of operations, and liquidity.

Business and Operational Risk Factors

The loss of customers could have an adverse effect on us. Although we provide services to a diverse portfolio of end markets and have long-standing relationships with many of our significant customers, our customers may unilaterally reduce, fail to renew, or terminate their contracts with us at any time. A loss of business from a significant customer, or a number of significant customers, could have a material adverse effect on our business, financial position, and results of operations.

Our industry is highly competitive. Our industry is served by numerous small, owner-operated private companies, a few public companies, and several large regional companies. In addition, relatively few barriers exist to prevent entry into most of the industries in which we operate. As a result, any organization that has adequate financial resources, and access to technical expertise, may become a competitor. Competition in our industry depends on numerous factors, including price. Certain of our competitors have lower overhead cost structures and, therefore, are able to provide their services at lower rates than we are currently able to provide. Our project and service work is frequently awarded through a competitive bidding process, which is standard in our industry. We are constantly competing for contracts based on pricing, schedule, and technical expertise. Competition can place downward pressure on our contract prices and profit margins, which may make it difficult to win the project or force us to accept contractual terms and conditions that are less favorable to us, thereby increasing the risk that, among other things, we may not realize profit margins at the same rates we have seen in the past or may become responsible for costs or other liabilities we have not incurred in the past.

We cannot be certain that our competitors will not develop the expertise, experience, and resources necessary to provide services that are superior in quality, and lower in price, to ours. Similarly, we cannot be certain that we will be able to maintain or enhance our competitive position within our industries or maintain a customer base at current levels. We may also face competition from the in-house service organizations of existing or prospective customers, particularly with respect to building services. Many of our customers employ personnel who perform some of the same types of building services that we do. We cannot be certain that our existing or prospective customers will continue to outsource building services in the future. If we are unable to compete effectively, we may experience a loss of customers, reduced profitability, or both, which if significant, could have a material adverse effect on our business, financial condition, and results of operations. Refer also to "Business -Competition" in Item 1 of this Form 10-K.

We are a decentralized company which presents certain risks. While we believe decentralization has enhanced our growth and enabled us to remain responsive to opportunities and to our customers' needs, it necessarily places significant control and decision-making powers in the hands of local management. This presents various risks, including the risk that we may be slower or less able to identify or react to external market conditions or problems affecting a key business than we would in a more centralized environment.

Our business may be affected by weather conditions. Adverse weather conditions, particularly during the winter season, could impact our construction services operations as those conditions affect our ability to safely and efficiently perform work outdoors in certain regions of the United States, adversely affecting the revenues and profitability of those operations. Unsafe outdoor air quality, such as that resulting from large wildfires in the United States or Canada, could have a similar adverse effect. However, the absence of snow in certain regions of the United States during the winter could also cause us to experience reduced revenues and profitability in our United States building services segment, as a portion of their revenues is generated from snow removal contracts. In addition, cooler than normal temperatures during the summer months could reduce the need for our services, particularly in our businesses that install or service air conditioning units, and result in reduced revenues and profitability during the period that such unseasonal weather conditions persist.

Our business may be affected by the work environment. We perform our work under a variety of conditions, including but not limited to, difficult terrain, challenging site conditions, busy urban centers where delivery of materials and availability of labor may be impacted, clean-room environments where strict procedures must be followed, and sites which contain harsh or hazardous conditions, especially at chemical plants, refineries, and other process facilities. Performing work under these conditions can increase the cost of such work or negatively affect efficiency and, therefore, our profitability.

Our dependence upon fixed price and similar contracts could adversely affect our business. We currently generate, and expect to continue to generate, a significant portion of our revenues from fixed price and similar contracts. We must estimate the total costs of a particular project to bid for fixed price, guaranteed maximum price, and similar contracts. Cost and scheduling estimates are based on a number of assumptions, including those about future economic conditions, commodity and other materials pricing, job-site productivity, cost and availability of labor, equipment, and materials, and supply chain efficiency, among other factors.

However, the actual cost of labor and materials, as well as the level of labor productivity achieved, may vary from our original estimates, something which we have experienced and may continue to experience due to inflationary pressures, supply chain challenges, labor market tightness, and elevated interest rates. These risks, inherent in the execution of projects subject to fixed price, guaranteed maximum price, and similar contracts, may cause actual gross profits from projects to differ from those we originally estimated and could result in reduced profitability or losses on projects. Depending upon the size of a particular project, variations from the estimated contract costs can have a significant impact on our operating results for any fiscal quarter or year.

We could incur additional costs to cover certain guarantees or other contractual requirements. In some instances, we guarantee completion of a project by a specific date or for a maximum price. In addition, certain of our contractual arrangements guarantee the achievement of agreed upon cost savings, certain performance standards, or a certain standard of quality. For other arrangements, including those within our government services operations, the terms of our contracts may include provisions which require us to achieve certain minority participation or small or disadvantaged business "set-aside" goals. If we subsequently fail to meet such guarantees, or comply with such provisions, we may be held responsible for costs resulting from such failures, including payment of penalties or liquidated or other damages. To the extent that any of these events occur, the total costs of a project could exceed the original estimated costs, and we would experience reduced profits or, in some cases, a loss.

Many of our contracts, especially our building and industrial services contracts, may be canceled or delayed on short notice, and we may be unsuccessful in replacing such contracts if they are canceled or as they are completed or expire. For example, in recent years, our building services operations were unsuccessful in retaining certain contracts upon rebid and our industrial services operations were adversely impacted by the deferral or delay of several projects. We could experience a decrease in revenues, net income, and liquidity if any of the following occur:

customers cancel a significant number of contracts or delay services or projects;

we fail to win a significant number of our existing contracts upon re-bid;

we complete a significant number of non-recurring projects and cannot replace them with similar projects; or

we fail to reduce operating and overhead expenses consistent with any decrease in our revenues.

Uncertainty surrounding the timing of contract awards, or project cancellations or delays, can also present difficulties in matching our workforce size with contract needs. In some cases, in anticipation of contract awards, we maintain and bear the cost of a ready workforce that is larger than necessary under our existing contract portfolio. When a contract is canceled or delayed, or an anticipated contract award is not received, it may result in lower profitability as a result of labor under-utilization, or additional costs resulting from reductions in staff, which could have a material adverse effect on our business, financial condition, and results of operations.

We may be unsuccessful in generating internal growth. Our ability to generate internal growth will be affected by, among other factors, our ability to:

expand the range of services offered to customers to address their evolving needs;

attract new customers; and

retain and/or increase the number of projects performed for existing customers.

In addition, existing and potential customers may reduce the number or size of projects available to us because of general economic conditions or due to their inability to obtain capital or pay for services we provide. Many of the factors affecting our ability to generate internal growth are beyond our control, and we cannot be certain that our strategies will be successful or that we will be able to generate cash flow sufficient to fund our operations and to support internal growth. If we are not successful, we may not be able to achieve internal growth, expand operations, or grow our business.

Fluctuating foreign currency exchange rates could impact our financial results. Until the sale of our United Kingdom operations on December 1, 2025, which in 2025 accounted for approximately 3% of our revenues, our reported financial position and results of operations were exposed to the effects (both positive and negative) that fluctuating exchange rates had on the process of translating the financial statements of our United Kingdom operations, which were denominated in the British pound, into the U.S. dollar. The factors that impact exchange rate fluctuation, including macroeconomic and geopolitical conditions, are outside of our control.

As part of our risk management strategy, we are effectively self-insured against certain potential liabilities. Although we maintain insurance policies with respect to a broad range of risks, including automobile liability, general liability, workers' compensation, and property damage, these policies do not cover all possible claims and certain of the policies are subject to large deductibles and retentions. In addition, we maintain a wholly-owned captive insurance subsidiary to manage certain of our insurance liabilities. Accordingly, we are effectively self-insured for a substantial number of actual and potential claims.

Further, if any of our insurance carriers defaulted on its obligations to provide insurance coverage by reason of its insolvency or for other reasons, our exposure to claims would increase and our profits would be adversely affected. Our estimates for unpaid claims and expenses are based on known facts, historical trends, and industry averages, utilizing the assistance of an independent third-party actuary. The determination of such estimated liabilities and their appropriateness are reviewed and updated at least quarterly. However, these liabilities are difficult to assess and estimate due to many relevant factors, the effects of which are often unknown, including the severity of an injury or damage, the determination of liability in proportion to other parties, the timeliness of reported claims, the effectiveness of our risk management and safety programs, denial of coverage by our insurance carriers, and the terms and conditions of our insurance policies and/or customer contracts. Our accruals are based upon known facts, historical trends and our reasonable estimate of future expenses, and we believe such accruals are adequate. However, unknown or changing trends, risks, or circumstances, such as increases in claims, a weakening economy, increases in medical costs, changes in case law or legislation, or changes in the nature of the work we perform, could render our current estimates and accruals inadequate. In such case, adjustments may be required to increase our insurance liabilities in the period that the experience becomes known.

External market conditions, including catastrophic losses resulting from an increase in severe weather events, among other factors, have resulted in an insurance market that is characterized by higher premiums, diminished capacity, and more conservative underwriting. If these market conditions persist, or if we experience an increase in the number or severity of claims incurred, insurance carriers may be unwilling, in the future, to provide our current levels of coverage without a significant increase in insurance premiums, self-insured retention limits, or collateral requirements to cover our obligations to them. Increased collateral requirements may be in the form of additional letters of credit, surety bonds, and/or cash, and an increase in collateral requirements could significantly reduce our liquidity. If insurance premiums or self-insured retention limits increase, and/or if insurance claims are higher than our estimates, our profitability could be adversely affected.

Failure to provide our services in accordance with professional standards or contractual requirements could expose us to significant monetary damages. Our services often involve professional judgments regarding the planning, design, development, construction, or operations and management of complex facilities. Although we have adopted a range of insurance, risk management, and risk avoidance programs designed to reduce potential liabilities, a catastrophic event at one of our project sites or a completed project, resulting from the services we have performed, could result in significant professional, product, and/or personal injury liability, as well as warranty or other claims against us and reputational harm. These liabilities could exceed our insurance limits or impact our ability to obtain insurance in the future. Further, even where insurance coverage applies, such policies have limits and deductibles or retentions, which could result in our assumption of exposure for certain amounts with respect to any claim filed against us. In addition, customers or subcontractors who have agreed to indemnify us against any such liabilities or losses might refuse or be unable to uphold their obligations to us, or we may be liable to our customers based on the terms of our contracts, which may require us to provide indemnification to them. An uninsured claim, either in part or in whole, as well as any claim covered by insurance but subject to a policy limit, high deductible/retention, or the denial of coverage by an insurance carrier, could have a material adverse effect on our business, financial condition, and results of operations.

Our business strategy relies, in part, on acquisitions to sustain our growth, and these transactions present certain risks and uncertainties. As part of our growth strategy, we acquire companies that expand, complement, and/or diversify our businesses. However, there is no guarantee that we will be successful in identifying targets that meet our requirements for acquisition. We may also face increased competition from other potential acquirers, including those who may have greater financial resources available to them or who may be in a position to offer more favorable terms to the target company. This competition may limit our ability to pursue acquisition opportunities. Additionally, circumstances beyond our control, such as elevated interest rates, inflation and potential macroeconomic disruptions, may hinder our ability to pursue and complete acquisitions. Further, realization of the anticipated benefits of an acquisition, such as our acquisition of Miller Electric Company, and avoiding or mitigating the potential risks associated with an acquisition, will depend, among other things, upon our ability to: (a) effectively conduct due diligence to identify and mitigate potential issues at companies we propose to acquire, (b) recognize incompatibilities or other obstacles to the successful integration of the acquired business with our other operations, and (c) gain greater efficiencies and scale that will translate into reduced costs or anticipated synergies in a timely manner. However, there can be no assurance that an acquisition we may make in the future will provide the benefits anticipated when entering into the transaction. Acquisitions we have completed, and future acquisitions we may make, could expose us to operational challenges and risks, including the diversion of management's attention from our existing businesses, the failure to retain key personnel or customers of the acquired business, and the assumption of unknown liabilities of the acquired business for which there are inadequate reserves. While the former owners of an acquired company may agree as part of our purchase agreements to indemnify us against certain historical liabilities of the target company, such indemnification may be subject to time limits, deductibles, caps and exclusions, and such former owners might be unable or unwilling to uphold those obligations to us. Our ability to sustain our growth and maintain our competitive position may be affected by our ability to identify and acquire desirable businesses and successfully integrate any acquired business.

In addition, while we work to rapidly implement or maintain internal controls and financial reporting standards and procedures in the businesses we acquire, including integrating such acquired businesses into our consolidated financial reporting systems and controls, we cannot be certain that such implementation and integration will be quickly and effectively completed. Our internal control processes and procedures with respect to such businesses may need to be adjusted or enhanced in order to ensure that such businesses are in compliance with the regulations we are subject to as well as our internal policies and standards. Such changes could result in significant additional costs to us and could require the diversion of management's attention from our existing businesses or other strategic initiatives.

Amounts included in our remaining performance obligations may not result in actual revenues or translate into profits. Many contracts are subject to cancellation or suspension on short notice at the discretion of the client, and the contracts in our remaining performance obligations are subject to changes in the scope of services to be provided as well as adjustments to the costs relating to the contract. The risk of contracts included in our remaining performance obligations being delayed or canceled generally increases during economic slowdowns, periods of restrictive credit markets, or in response to significant fluctuations in commodity prices. Accordingly, revenue from remaining performance obligations may not be realized. If our remaining performance obligations fail to materialize, we could experience a decline in profitability, which could result in a deterioration of our financial position and liquidity.

We recognize revenue for the majority of our construction projects based on estimates; therefore, variations of actual results from our assumptions may reduce our profitability. As discussed in further detail in the "Critical Accounting Policies and Estimates" section included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations, revenue is recognized as performance obligations are satisfied and earnings or losses recognized on individual contracts are based on estimates of contract price, costs, and profitability. Changes in estimates of transaction prices as well as estimated costs are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. Consequently, changes in estimates, or variations of actual results from previous projections, on an unusually large project, or on a number of average size projects, could be material and could have an adverse impact on our financial condition, results of operations, and cash flows.

We are increasingly dependent on sophisticated information technology systems; our business and results of operations are subject to adverse impacts due to the disruption, failure, or breaches of these systems. We and our customers and third-party providers rely on information technology systems, hardware, and software, including third-party "cloud based" systems, to run critical accounting, project management, and financial information systems. We rely upon security measures, systems redundancy, and third-party products and services to attempt to secure our information technology systems and the confidential, proprietary, and sensitive information they contain. However, our information technology systems and data, and that of our customers and third-party providers, are subject to cybersecurity incidents, such as hacking, computer viruses or other malicious or destructive software, ransomware, denial of service attacks, malicious social engineering and other intrusions, encryption, erasure, failure, and damage by individuals (which may include our and our third-party providers' employees), groups or nation states or state-sponsored threats. Such cybersecurity incidents could result in operational disruption and information misappropriation, such as theft of intellectual property or inappropriate disclosure of customer data or confidential, sensitive, or personal information, or in reputational harm with customers. While we maintain insurance coverage for these types of cybersecurity incidents, such policies may not completely provide coverage for, or completely offset, the costs associated with such incidents, including losses from delays in our ability to provide services to our customers, reputational harm, or the costs to improve security against future similar threats. We are continuously developing and enhancing our controls, processes, and practices designed to protect our systems, computers, software, data, and networks from attack, damage, or unauthorized access. This continued development and enhancement requires us to expend additional resources. However, we may not anticipate or combat all types of potential disruptions or breaches. Threats are continually evolving and threat actors may adopt new or different means of breaching our information technology systems and data, including the potential use of AI tools to engage in automated, targeted, and coordinated attacks. As cybersecurity threats become more sophisticated and difficult to detect, our ability to promptly prevent, detect and mitigate the effects of cybersecurity incidents may be impacted, potentially resulting in more material adverse effects. As such threats increase in frequency and sophistication, we could be required to expend additional capital and other resources, including costs to deploy additional personnel and protection technologies, train employees, and engage third-party experts and consultants. Additionally, as many of our employees use our information technology systems to collaborate with colleagues in different geographic locations and access our systems and those of our customers remotely, we and our customers may be subject to heightened security risks, including the risks of cyber-attacks.

For additional information on our strategy and processes for assessing, identifying, and managing the risks posed by cybersecurity threats, and the management and oversight of such efforts, refer to Part I, Item 1C. Cybersecurity.

The proper functioning of our information technology systems could also be impacted by other causes and circumstances beyond our control, including malware embedded in third-party applications, the decision by software vendors to discontinue further development, integration, or long-term software maintenance support for our information systems, or hardware interruption, damage or disruption as a result of power outages, natural disasters, or computer network failures. Errors or other defects in the design or implementation of hardware or software applications by our employees or third-party providers could also disrupt our networks, information systems or data. System redundancy may be ineffective or inadequate, and the Company's disaster recovery and business continuity planning may not be sufficient to address all potential cybersecurity incidents or other disruptions. We may also utilize new information technology tools, including AI tools, in certain business functions, and such tools could be subject to malfunction, security vulnerabilities, or algorithmic flaws (including AI generation of false or biased information). Unsettled regulations and case law regarding the ownership of intellectual property generated or used by AI could also expose us to claims of copyright or license infringement or other liability resulting from our use of such tools. Key business processes are subject to interruption to the extent that our information technology systems, or those of our customers or third-party providers, are disabled for a long period of time. Such operational disruptions and/or misappropriation or inappropriate disclosure of information could result in lost or reduced revenues, negative publicity, loss of customers or contracts, or business delays that could have a material adverse effect on our business, financial position, and results of operations.

In addition, laws and regulations governing data privacy and the unauthorized disclosure of confidential information, including the California Consumer Privacy Act, the California Privacy Rights Act, state biometric laws, and other emerging

U.S. state privacy laws pose increasingly complex compliance challenges and could potentially elevate our compliance costs. Any failure to comply with these laws and regulations, or an exposure or exfiltration of information covered by such laws and regulations, including, without limitation, in connection with a cybersecurity incident, could have a negative impact on our reputation or result in significant penalties and legal liability. Increased costs in this area could adversely impact our financial condition, results of operations, and cash flow.

Financial Risk Factors

A material portion of our business depends on our ability to provide surety bonds. We may be unable to compete for or work on certain projects if we are not able to obtain the necessary surety bonds. Our construction contracts frequently require that we obtain from surety companies, and provide to our customers, payment and performance bonds as a condition to the award of such contracts. Such surety bonds secure our payment and performance obligations. Under standard terms in the surety market, surety companies issue bonds on a project-by-project basis and can decline to issue bonds at any time or require the posting of collateral as a condition to issuing any bonds. Current or future market conditions, as well as changes in our sureties' assessment of our or their own operating and financial risk, could cause our surety companies to decline to issue, or substantially reduce the amount of, bonds for our work or to increase our bonding costs. These actions can be taken on short notice. If our surety companies were to limit or eliminate our access to bonding, our alternatives would include seeking bonding capacity from other surety companies, increasing business with clients that do not require bonds, or posting other forms of collateral for project performance, such as letters of credit, parent company guarantees, or cash. However, we may be unable to secure these alternatives in a timely manner, on acceptable terms, or at all. Accordingly, if we were to experience an interruption or reduction in the availability of bonding, we may be unable to compete for or work on certain projects. Increases in the costs of surety bonds could also adversely impact our profitability.

Our results of operations could be adversely affected as a result of goodwill and identifiable intangible asset impairments. When we acquire a business, we record an asset called "goodwill" equal to the excess of the consideration transferred over the fair value of the net tangible and identifiable intangible assets acquired. Goodwill and indefinite-lived intangible assets are not amortized but instead evaluated for impairment annually, or more frequently if events or circumstances indicate that the carrying amount of the asset may be impaired. Impairment may result from a deterioration in macroeconomic conditions, declining financial performance, deterioration in the operational environment, or changes in the manner in which acquired assets are used. Significant judgment is required in determining whether goodwill and indefinite-lived intangible assets are impaired and assumptions utilized for purposes of our impairment testing may change in future periods. Our estimates and assumptions could prove to be inaccurate predictions of the future. Significant adverse changes to external market conditions or our internal forecasts, if any, could result in future impairment charges. It is not possible at this time to determine if any future impairment charge will result or, if it does, whether such a charge would be material to our results of operations. For further discussion of our impairment testing, see Note 8 - Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data.

Failure to maintain effective internal controls over financial reporting could adversely impact our ability to timely and accurately report financial results and comply with our reporting obligations, which could materially affect our business. Regardless of how internal financial reporting control systems are designed, implemented, and enforced, they cannot ensure with absolute certainty that our policy objectives will be met in every instance.

Because of the inherent limitations of all such systems, our internal controls over financial reporting may not always prevent or detect misstatements. Failure to maintain effective internal control over financial reporting could adversely affect our ability to accurately and timely report financial results, to prevent or detect fraud, or to comply with the requirements of the SEC or the Sarbanes-Oxley Act of 2002, which could necessitate a restatement of our financial statements, and/or result in an investigation, or the imposition of sanctions, by regulators. Such failure could additionally expose us to litigation and/or reputational harm, impair our ability to obtain financing, or increase the cost of any financing we obtain. All of these impacts could adversely affect the price of our common stock and our business overall.

Legal and Regulatory Risk Factors

We are subject to many laws and regulations in the jurisdictions in which we operate; changes to such laws and regulations may result in additional costs and impact our operations. We are committed to upholding the highest standards of corporate governance and legal and ethical compliance. We are subject to many laws and regulations, including various laws and regulations that apply specifically to U.S. public companies. These include the rules and regulations of the New York Stock Exchange, the Sarbanes-Oxley Act of 2002, and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as the various regulations, standards, and guidance put forth by the SEC and other federal and state governmental agencies to implement and enforce those laws. New laws, rules, and regulations, or changes to existing laws or their interpretations, could create added legal and compliance costs and uncertainty for us. Our efforts to comply with evolving laws, regulations, and reporting standards may increase our general and administrative expenses, divert management time and attention, or limit our operational flexibility, all of which could have a material adverse effect on our business, financial position, and results of operations. Many of our non-public competitors are not subject to these laws and regulations and the related costs and expenses of compliance.

Our failure to comply with environmental laws could result in significant liabilities. Our operations are subject to various laws, including environmental laws and regulations, among which many deal with the handling and disposal of hazardous or universal waste products, polychlorinated biphenyls, per- and polyfluoroalkyl substances, and fuel storage. A violation of such laws and regulations, or a release of or exposure to such substances, including mold, lead paint, and asbestos, has and may in the future, expose us to various claims, including claims by third parties, as well as remediation costs and fines. We own and lease many facilities. Some of these facilities contain hazardous materials, such as asbestos, and fuel storage tanks, which may be above or below ground. If there is a release of such hazardous materials, or these tanks were to leak, we could be responsible for the cost of remediation as well as potential fines. As a part of our business, we also install fuel storage tanks and are sometimes required to deal with hazardous materials, all of which may expose us to environmental liability. In addition, some of our operations, particularly those servicing oil and natural gas refineries, are subject to the risk of accidental release of hazardous materials that have in the past and have the potential to result in injuries or fatalities involving our employees or third parties, property damage, or environmental contamination. If our personnel cause or are alleged to have caused any such release, it may result in claims for indemnification under our contracts with customers, claims from third-parties or local communities impacted by such release, or investigations or regulatory action by federal, state or local environmental, occupational, health and safety or other authorities. These risks could result in a material adverse effect on our business, operating results, financial position, and cash flows, and in some cases, on our reputation or our ability to obtain projects from customers.

New laws and regulations, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or leaks, exposure to or the release of materials subsequently identified as hazardous by a governmental authority, the imposition of new clean-up requirements, or the exposure of our employees or other contractors to hazardous materials, could require us to incur significant costs or become the basis for new or increased liabilities that could harm our financial position and results of operations, although certain of these costs might be covered by insurance. In some instances, we have obtained indemnification or covenants from third parties (including predecessors or lessors) for such clean-up and other obligations and liabilities, and we believe such indemnities and covenants are adequate to cover such obligations and liabilities. However, such third-party indemnities or covenants may not cover all of such costs or third-party indemnitors may default on their obligations. In addition, unanticipated obligations or liabilities, or future obligations and liabilities, may have a material adverse effect on our business operations. Further, we cannot be certain that we will be able to identify, or be indemnified for, all potential environmental liabilities relating to any acquired business. See Note 15 - Commitments and Contingencies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, for more information regarding any significant legal proceedings in which we are involved.

Adverse resolution of litigation and other legal and regulatory proceedings may harm our operating results or financial position. From time to time, we are a party to lawsuits and other legal proceedings, most of which occur in the normal course of our business. These actions and proceedings may involve actual or threatened claims by customers, employees, or other third parties for, among other things, compensation or indemnification for alleged personal injury, workers' compensation, employment discrimination, breach of contract, property damage, or other general commercial disputes.

In addition, we have been, and may in the future be, subject to class action claims alleging violations of the Fair Labor Standards Act and state wage and hour laws. Litigation and other legal proceedings can be expensive, lengthy, and disruptive to normal business operations, and their outcome is inherently uncertain and difficult to accurately predict or quantify. In addition, plaintiffs in many types of actions may seek punitive damages, civil penalties, consequential damages or other losses, or injunctive or declaratory relief. An unfavorable resolution of a particular legal proceeding or claim, whether through a settlement, mediation, court judgment, or otherwise, could have a material adverse effect on our business, operating results, financial position, and cash flows, and in some cases, on our reputation or our ability to obtain projects from customers, including governmental entities. See Note 15 - Commitments and Contingencies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, for more information regarding any significant legal proceedings in which we are involved.

We may incur liabilities or suffer negative financial impacts relating to occupational, health, and safety matters. Our operations are subject to extensive laws and regulations relating to the maintenance of safe conditions in the workplace. While we have invested, and will continue to invest, substantial resources in our robust occupational, health, and safety programs, many of our businesses involve a high degree of operational risk, and there can be no assurance that we will avoid significant exposure. These hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment, and other consequential damages, and could lead to suspension of operations, large damage claims, an increase in employee turnover, and, in extreme cases, criminal liability. Any of the foregoing could result in financial losses or reputational harm, which could have a material adverse impact on our business, financial condition, and results of operations.

Our customers seek to minimize safety risks on their sites and they frequently review the safety records of contractors during the bidding process. Accordingly, if our safety record were to substantially deteriorate over time, we might become ineligible to bid on certain work and our customers could cancel our contracts and/or not award us future business.

Our failure to comply with anti-bribery statutes, such as the Foreign Corrupt Practices Act, or sanction regulations, could result in fines, criminal penalties, and other sanctions that could have an adverse effect on our business. The U.S. Foreign Corrupt Practices Act (the "FCPA"), and similar anti-bribery laws in other jurisdictions, generally prohibit companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or retaining business or securing an improper advantage. In addition, sanctions against foreign persons and entities have increased in recent years, especially in connection with the war in Ukraine and ongoing trade and diplomatic disputes between the U.S. and China. Our policies require that all of our employees, subcontractors, vendors, and agents worldwide must comply with applicable anti-bribery and sanction laws. However, there is no assurance that our policies and procedures to ensure compliance with the FCPA and similar anti-bribery and sanction laws will eliminate the possibility of liability under such laws for actions taken by our employees, agents, and intermediaries. If we were found to be liable for violations under the FCPA, or similar anti-bribery or sanction laws, either due to our own acts or omissions or due to the acts or omissions of others, we could incur substantial legal expenses and suffer civil and criminal penalties, which could have a material adverse effect on our business, financial condition, and results of operations, as well as our reputation. In addition, whether or not such expenses, penalties, or sanctions are actually incurred, the actual or alleged violation of the FCPA, or any similar anti-bribery or sanction laws, could have a negative impact on our reputation.

Opportunities within the government sector could lead to increased governmental rules and regulations applicable to us. When we perform work as a federal government contractor/subcontractor, or if we perform work on a project that has received federal government funding, we are subject to a number of procurement rules and other regulations, any deemed violation of which could lead to fines or penalties or a loss of business. Government agencies routinely audit and investigate government contractors. Government agencies may review a contractor's performance under its contracts, cost structure, and compliance with applicable laws, regulations, and standards. If government agencies determine through these audits or reviews that costs are improperly allocated to specific contracts, they will not reimburse the contractor for those costs or may require the contractor to refund previously reimbursed costs. If government agencies determine that we are engaged in improper activity, or if we are found to have violated laws or regulations, we may be subject to civil and criminal penalties and debarment or suspension from doing business with the government. Government contracts are also subject to renegotiation of terms by the government, termination by the government prior to the expiration of the term, and non-renewal by the government.

Human Capital and Labor Risk Factors

The departure, loss or incapacitation of key personnel could disrupt our business. We depend on the continued efforts of our senior management and other key employees. The departure or loss of key personnel, including as a result of illness or other incapacitation, or the inability to hire and retain qualified executives, could negatively impact our ability to manage our business, successfully execute for our customers or sustain valuable customer relationships. While we have established and regularly review management succession plans, the inadequacy of any such succession plans in addressing a particular loss or our failure to successfully implement such succession plans may adversely affect our business.

We may be unable to attract and retain skilled employees. Our ability to grow and maintain productivity and profitability will be limited by our ability to employ, train, and retain skilled personnel necessary to meet our requirements. We are dependent upon a workforce of approximately 44,000 employees, including our project managers and field supervisors who are responsible for managing our projects, and there can be no assurance that any individual will continue in his or her capacity for any particular period of time. The loss of such qualified employees could have an adverse effect on our business. We cannot be certain that we will be able to maintain an adequate skilled labor force necessary to operate efficiently and to support our business strategy or that labor expenses will not increase as a result of a shortage in the supply of these skilled personnel. We also rely on third-party subcontractors to complete portions of some of our projects and those subcontractors are subject to the same challenges and uncertainty in employing, training and retaining an adequate qualified labor force to meet our needs.

The availability and costs to adequately train and maintain a skilled labor force could be impacted by factors we cannot control, including changes in the unemployment rate, prevailing wage rates, benefit costs, potential labor force disruptions, and competition for labor from our competitors in the markets we serve. Labor shortages or increased labor costs, such as those experienced in recent years, could impair our ability to provide services to our customers (or the ability of third-party subcontractors to provide services to us), maintain our business, or grow our revenues. Federal or state regulations, which seek to prohibit non-competition agreements with employees may also impact our ability to retain key employees by reducing barriers to individuals with such agreements leaving to work for our competitors.

Our unionized workforce could adversely affect our operations; our participation in many multiemployer pension plans could result in substantial liabilities being incurred. As of December 31, 2025, approximately 62% of our employees were covered by collective bargaining agreements. However, only two of our collective bargaining agreements are national or regional in scope, and not all of our collective bargaining agreements expire at the same time. Although the majority of these agreements prohibit strikes and work stoppages, we cannot be certain that strikes or work stoppages will not occur in the future. Strikes or work stoppages likely would adversely impact our relationships with our customers and could have a material adverse effect on our financial position, results of operations, and cash flows.

We contribute to approximately 200 multiemployer pension plans. Under the Employee Retirement Income Security Act, we may become liable for our proportionate share of a multiemployer pension plan's underfunding if we cease to contribute to that pension plan or significantly reduce the employees in respect of which we make contributions to that pension plan. Our potential liability for unfunded liabilities could be material. See Note 14 - Retirement Plans of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for additional information regarding multiemployer pension plans.

Risk Factors Related to the Ownership of our Common Stock

Certain provisions of our corporate governance documents could make an acquisition of us, or a substantial interest in us, more difficult. The following provisions of our certificate of incorporation and by-laws, as currently in effect, as well as Delaware law, could discourage potential proposals to acquire us, delay or prevent a change in control of us, or limit the price that investors may be willing to pay in the future for shares of our common stock:

our certificate of incorporation permits our board of directors to issue "blank check" preferred stock and to adopt amendments to our by-laws;

our by-laws contain restrictions regarding the right of our stockholders to nominate directors and to submit proposals to be considered at stockholder meetings;

our certificate of incorporation and by-laws limit the right of our stockholders to call a special meeting of stockholders and to act by written consent; and

we are subject to provisions of Delaware law, which prohibit us from engaging in any of a broad range of business transactions with an "interested stockholder" for a period of three years following the date such stockholder becomes classified as an interested stockholder.

Climate Change Related Risk Factors

Climate change and related environmental issues could have a material adverse impact on our business, financial condition, and results of operations. Climate change related events, such as increased frequency and severity of storms, floods, wildfires, droughts, hurricanes, freezing conditions, and other natural disasters, may have an adverse impact on our business, financial condition, and results of operation. While we have invested in programs to mitigate the risk that these events disrupt our ability to serve our customers, and also maintain insurance coverage to offset the costs which could result, these events pose inherent risks regardless of where or how we conduct our business. For example, severe weather or a catastrophic natural disaster could negatively impact our and our customers' offices, facilities, or job sites. Access to clean water and reliable energy where we conduct our business is also critical to our operations.

Accordingly, severe weather events or natural disasters have the potential to disrupt our and our customers' businesses and may cause us to experience work stoppages, project delays or cancellations, financial losses, and additional costs to resume operations, in addition to potential adverse impacts on the health and safety of our workforce and their ability to work or travel. Further, climate change poses direct physical risks to infrastructure across the market sectors we serve, both as a result of chronic environmental changes, such as rising sea levels and temperatures, as well as acute events, such as hurricanes, droughts, and wildfires. These impacts, and the costs to address them, could result in fewer resources for strategic investment by our customers, which could result in a decrease in demand for certain of our services. Any of these events could have a material adverse impact on our business, financial condition, and results of operations.

We may be affected by market or regulatory responses to climate change. Public concern about climate change has, at times, resulted in the increased focus of local, state, regional, national, and international regulatory bodies on greenhouse gas ("GHG") emissions and climate change issues. Legislation to regulate GHG emissions has periodically been introduced in the U.S. Congress, and there has been a wide-ranging policy debate, both in the United States and internationally, regarding the impact of these gases and possible means for their regulation. Several states in the United States have proposed or adopted laws that require reporting of GHG emissions, or that a percentage of our fleet be comprised of electric vehicles. Such laws or regulations enacted by the federal government or state and local governments or agencies, and/or any international agreements to which the United States may become a party that control or limit GHG emissions or otherwise seek to address climate change, could result in increased compliance costs for us and our clients or have other impacts on our clients, including those who are involved in the exploration, production, or refining of fossil fuels, or who emit greenhouse gases through the combustion of fossil fuels or through the mining, manufacture, utilization, or production of materials or goods. Such policy changes could increase the costs of projects for our clients or, in some cases, prevent a project from going forward, thereby potentially reducing the need for certain of our services, which could in turn have a material adverse effect on our business, financial condition, and results of operations. In addition, compliance with legislation requiring us to increase the mix of electric vehicles within our fleet will be difficult as the electric vehicles currently available do not meet our fleet requirements. However, policy changes and climate legislation could also increase the overall demand for our services as our clients and partners work to comply with these policies, such as by decarbonizing their industries, transitioning from fossil fuels to renewable energy sources, reducing their energy consumption, and developing integrated and sustainable solutions, all of which could have a positive impact on our business. We cannot predict with certainty what the effect of such regulation may be on us or our customers.

In addition, in March 2024, the SEC finalized new rules that would require significant climate-related disclosures by public companies, including evaluation and disclosure of material climate-related risks and opportunities, GHG emissions inventory, climate-related targets and goals, and financial impacts of physical and transition risks. While these rules are currently stayed pending legal challenges, and are not supported under the current administration, it is not certain whether they, or similar future rules, will go into effect. Other legislation, including certain state laws, have been passed that would require similar climate-related disclosure. To the extent that such new rules become effective, our legal, accounting, and other compliance expenses may increase and may divert management time and attention. We may also be exposed to legal or regulatory action or claims as a result of these new regulations. All of these risks could have a material adverse effect on our business, financial position, and/ or stock price.

We may be unable to achieve our current or future climate commitments and targets, or we may incur substantial costs in meeting such targets. To help mitigate the impacts of GHG emissions on climate change, EMCOR has established initial carbon-based fuel consumption and GHG emission reduction targets. However, achievement of such targets, or similar targets that may be established in the future, is subject to risks and uncertainties, many of which are outside of our control. These risks and uncertainties include, but are not limited to: (a) our ability to execute our operational strategies and achieve our goals within the currently projected costs and the expected timeframes; (b) the availability and cost of alternative fuels, electrical charging infrastructure, off-site renewable energy, and other materials and components; (c) unforeseen design, operational, and technological difficulties; (d) the outcome of research efforts and future technology developments, including alternate or more fuel efficient vehicles for our fleet, such as hybrid or electric vehicles, the availability and prices of which have been and may in the future be impacted by the rescission of electric vehicle tax credits, tariffs imposed on the import of vehicles to the United States, and other disruptions to the global supply of vehicles generally; (e) regulations and requirements that restrict or prohibit our ability to impose requirements on third-party contractors; (f) an acquisition of or merger with another company that has not adopted similar targets and goals or whose progress towards reaching its goals is not as advanced as ours; and (g) exogenous macroeconomic or supply chain shocks, which could result in fluctuations in our fuel consumption and GHG emissions in a given period. In addition, we could be required to expend amounts in future periods as we continue to work towards achieving our targets, which may have a material effect on our business, financial condition, results of operations, or liquidity.
