Segments

The Company operates in two segments, (i) Owner Direct Relationships (“ODR”), in which the Company performs owner direct projects and/or provides maintenance or service primarily on mechanical, plumbing or electrical systems, building controls and specialty contracting projects to existing buildings direct to, or assigned by, building owners or property managers, and (ii) General Contractor Relationships (“GCR”), in which the Company generally manages new construction or renovation projects that involve primarily mechanical, electrical, and/or plumbing (“MEP”) services awarded to the Company by general contractors or construction managers.

ODR Segment. The Company’s key business initiative for its ODR segment is to position itself as a value-added, indispensable partner to building owners in mission-critical markets, providing full life-cycle capabilities from concept design and engineering through system commissioning and around-the-clock service and maintenance primarily to their existing buildings. The Company remains focused on the scalability of its organic business through partnering directly with building owners. The Company believes that its ODR services offerings provide a distribution channel through which it can continue to deliver an expanded offering of value-added services direct to building owners that further reinforces its value proposition and differentiated capabilities. In addition, by establishing successful, long-term partnerships with building owners, the Company has positioned itself to provide reoccurring maintenance services, which it believes improves revenue predictability and could increase economic resilience. The Company provides its ODR business services through the following project delivery methodologies and other service offerings:

• Integrated Facility Planning. The Company provides professional and consultative services to building owners, helping them proactively plan future investments, anticipate opportunities, and align facility needs with long-term business goals. These services include engineer-led facility assessments, identification and support of capital planning needs for new and existing facilities through the analysis of existing facility data, as well as program management support.
• Replacements & Retrofit. The Company provides system and/or facility assessments to determine the best solution for the building owner’s assets. Based on the assessments performed, the Company tailors MEP equipment upgrades for its customers’ system and/or facility. Examples of MEP equipment upgrades and products include providing installed

equipment solutions, equipment retrofitting/restoration, off-site equipment skids, temporary equipment fixes and comprehensive system replacements.

• Rental Equipment. The Company provides turnkey rental equipment solutions to support building owners during planned replacements, emergency repairs, and construction outages. These services go beyond simply supplying temporary equipment, they include system design, ensuring existing system compatibility, managing all necessary connections, as well as overseeing installation, maintenance, and removal.
• Maintenance and Repairs. The Company provides comprehensive inspection, troubleshooting, repair, and services to ensure the safe, efficient, and reliable operation of building systems. Ongoing maintenance and operations are essential for building functionality, safety, and energy efficiency. The Company’s skilled technicians specialize in servicing all critical building systems, addressing root causes of issues, and delivering tailored maintenance solutions through “evergreen” contracts. The Company’s predictive maintenance solutions include:
• 24/7 emergency service and repairs;

Through consulting and energy engineer-led assessments, it develops tailored solutions and long-term roadmaps focused on reducing carbon emissions while optimizing energy efficiency and system performance.

Due to the Company’s ongoing relationships with certain building owners established through certain of its service offerings, the Company believes it is well positioned with those owners when they initiate capital construction projects. As a result, the ongoing relationship with the customer, along with the maintenance, time-and-materials, building automation upgrades, critical system repair work, and data driven insights often lead, drive and support the revenue associated with owner direct projects.

GCR Segment. The Company provides its GCR segment services through the following project delivery methodologies:

• Plan & Spec Bidding. Plan & Spec bidding is a competitive bid process among multiple contractors bidding on nearly or fully complete design documents based on a lump sum price for delivery of the project. The Company believes price is the predominant selection criteria in this process.
• Design/Build or Design/Assist. Design/Build or Design/Assist is a process in which a specialty contractor is selected among competing contractors using best value methodology. In best value, the Company believes the selection is made primarily upon qualifications and project approach, and secondarily upon select cost factors. Cost factors are usually limited to a fixed fee, expense estimate and an estimate of the cost of work. With Design/Assist, the specialty contractor is typically contracted early in the design process to provide design and preconstruction input as needed to assist the customer in maintaining the established budget and completing design and drawings. This delivery option includes lump-sum or guaranteed maximum price on a fixed fee basis.

Strategy

The Company focuses on creating value for building owners by developing long-term relationships and becoming an indispensable partner to building owners with mission-critical systems. As part of its strategy, the Company utilizes a three pillar approach to scale its business; 1) to improve profitability and generate quality growth in its operations by shifting to the ODR segment; 2) to expand margins through evolved offerings, and 3) to scale the business through acquisitions. To accomplish these objectives, the Company currently is executing the following initiatives:

ODR Growth. In focusing on improved profitability and generating quality growth in its operations, the Company has dedicated and continues to dedicate its resources toward the growth of its ODR segment as the scope of offerings provided within the Company’s ODR segment typically yield higher margins when compared to its GCR segment. During fiscal year 2023, the Company eclipsed its ODR-related revenue target, generating a 50/50 segment revenue mix. For fiscal year 2024, the Company further expanded its growth within the ODR segment where it generated 66.6% of its total consolidated revenue, achieving its 2024 ODR segment revenue target of 65%-70%. The Company believes it maintains a disciplined approach, capable of providing a full life-cycle of engineered solutions and craft expertise enabling it to be a one-stop-shop for building owners. The Company continues to make investments to expand its ODR revenue by increasing the value it can offer to building owners and continues to evaluate areas in which it could expand the breadth of its offerings to better serve its customers. In addition, the Company continues to expand its owner-direct offerings to include other digital solutions to manage and monitor the performance of building systems, including data analytics, energy consumption and sustainability. These services allow the Company to develop new revenue streams, leveraging its professional services capabilities to support multi-location regional and national customers in core end-markets, and to drive energy retrofit and performance optimization projects for building owners.

The Company’s ODR revenue increased by 31.9% to $345.5 million for the year ended December 31, 2024 as compared to $262.0 million for the year ended December 31, 2023. The increase in year-over-year ODR segment revenue was primarily due to the Company's continued focus on the accelerated growth of its ODR business. In addition, ODR segment revenue increased in the aggregate by approximately $31.5 million due to the ACME Industrial Piping, LLC (“ACME”) and Industrial Air, LLC (“Industrial Air”) transactions. These entities were not acquired entities of the Company for the full year ending December 31, 2023. ODR gross profit increased $31.7 million, or 41.6%, due to the combination of an increase in revenue, higher margins driven by contract mix and as a result of the ACME and Industrial Air transactions. ODR gross profit percentage increased to 31.2% for the year ended December 31, 2024 from 29.0% for the year ended December 31, 2023, mainly driven by the mix of higher margin ODR segment work and net material gross profit write-ups.

Improved GCR Segment Margins. In the GCR segment, the Company’s efforts continue to focus on improving project execution and profitability by pursuing opportunities that are smaller in size and shorter in duration than the opportunities historically and where it can leverage its captive design and engineering services. The Company believes that it is appropriate in the current contracting environment to reduce risk and exposure to large, complex, non-owner direct projects where the trend has been for such jobs to provide risks that are difficult to mitigate. Currently, management believes the historical industry pricing and associated risks for this type of work does not align with the Company’s stakeholders’ expectations, and therefore, the Company continues to take steps to actively reduce these risks as it looks at future project selection and as it completes current projects.

The Company’s GCR revenue decreased by 31.9% to $173.3 million for the year ended December 31, 2024 as compared to $254.4 million for the year ended December 31, 2023. The decrease in GCR revenue was primarily due to the Company’s continued focus on the execution of its mix-shift strategy to ODR. GCR gross profit decreased $6.7 million, or 15.5%, primarily due to lower revenue despite higher margins. Gross profit improved to 21.1% for the year ended December 31, 2024 from 17.0% for the year ended December 31, 2023 primarily due to the Company becoming more selective when pursuing GCR projects.

Maintain a Diverse Customer, Geographic and Project Base. The Company has a distribution of revenue across end-use sectors that it believes reduces its exposure to negative developments in any given sector. Currently, the Company also has significant geographical diversification across regions that are generally located in the eastern parts of the United States, again reducing its exposure to negative developments in any single given region. The Company’s core market sectors consist of the following customer base with mission-critical systems:

• Healthcare, including research, acute care and inpatient hospitals for regional and national hospital groups;
• Industrial and manufacturing, including automotive, energy and general manufacturing plants;
• Data centers, including facilities composed of networked computers, storage systems and computing infrastructure that organizations use to assemble, process, store and disseminate large amounts of data;
• Life sciences, including organizations and companies whose work is centered around research and development focused on living things;
• Higher education, including both public and private colleges, universities and research centers; and
• Cultural and entertainment, including entertainment facilities (including casinos) and amusement rides and parks.

The Company also partners with building owners across other market sectors and believes that it is imperative that the partnerships formed between the Company and its building owners share similar core values.

Investment in Its Team Members. Employee development underpins the Company’s efforts to execute its strategy. The Company continues to actively concentrate managerial and sales resources on training and hiring experienced team members to sell and profitably perform ODR-related services. In many locations, the Company has added or upgraded its capabilities and the Company believes its investments and efforts have provided customer value and stimulated growth within the segment. The Company seeks to attract and retain quality team members by providing them an enhanced career path that offers a stable income, attractive benefits packages and excellent advancement opportunities. The Company invests in its team members through safety and wellness programs, robust internal communication, career development and training programs, recognition programs and succession planning initiatives.

Margin Expansion Through Evolved Offerings. The Company continues to focus on expanding its margins by evolving and enhancing its current offerings to building owners. This initiative reflects its commitment to driving sustainable growth, increasing operational efficiency and delivering greater value to its stakeholders. This evolution is designed to align more closely with current market demands, emerging customer preferences and operational efficiencies, which together contribute to margin expansion. The Company aims to differentiate itself from its competitors by being a one-stop-shop for building owners, capable of providing a full life-cycle of engineered solutions and craft expertise. By meeting diverse customer needs under one roof, the Company deepens customer loyalty. The Company believes that building owners value the convenience and reliability of a single point of contact, which fosters long-term partnerships and reoccurring business and may open doors to larger capital projects. In addition, by evolving its offerings, the Company is able to capture a greater share of the value chain.

Growth Through Acquisitions. The Company believes that it can further increase its cash flow and operating income by acquiring strategically synergistic companies that will increase the Company’s geographic footprint, supplement the Company’s current business model, address capability gaps and enhance the breadth of its offerings to better serve its customers. The Company has dedicated and continues to dedicate its resources to seek opportunities to acquire and integrate businesses that have attractive market positions, supports the Company’s ODR growth strategy, expands and/or supplements the Company’s current breadth of offerings and is culturally compatible. See Note 3 – Acquisitions in the accompanying notes to the Company’s consolidated financial statements for further information on the Company’s most recent acquisition activity.

Acquisitions

The Kent Island Transaction. On September 3, 2024 (the “Kent Island Effective Date”), Limbach Facility Services LLC (“LFS”), a Delaware limited liability company and wholly-owned subsidiary of the Company, Kent Island, and the owner of Kent Island (the “Kent Island Seller”) entered into a Purchase Agreement (the “Kent Island Purchase Agreement”) pursuant to which LFS purchased all of the outstanding equity interests in Kent Island from the Kent Island Seller (the “Kent Island Transaction”). The Kent Island Transaction closed on the Kent Island Effective Date. As a result of the Kent Island Transaction, Kent Island became a wholly-owned indirect subsidiary of the Company. Kent Island is a leading provider of building systems solutions in the Greater Washington, DC metro area, including suburban Maryland and Northern Virginia. Kent Island excels in designing, engineering, installing, servicing, and maintaining mechanical and plumbing systems for complex facilities. The acquisition expands the Company’s market share within its existing operating footprint, provides further exposure to an attractive customer base and supports the Company's continued ODR growth strategy.

The Consolidated Mechanical Transaction. On December 2, 2024 (the “Consolidated Mechanical Effective Date”), LFS, Consolidated Mechanical, and the owner of Consolidated Mechanical (the “Consolidated Mechanical Seller”) entered into a Purchase Agreement (the “Consolidated Mechanical Purchase Agreement”) pursuant to which LFS purchased all of the outstanding equity interests in Consolidated Mechanical from the Consolidated Mechanical Seller (the “Consolidated Mechanical Transaction”). The Consolidated Mechanical Transaction closed on the Consolidated Mechanical Effective Date. As a result of the Consolidated Mechanical Transaction, Consolidated Mechanical became a wholly-owned indirect subsidiary of the Company. Consolidated Mechanical serves the heavy industrial, power and commercial markets. Consolidated Mechanical is a premier provider of mechanical, millwright, steel fabrication, plumbing construction, maintenance, and outage services to owners of complex process systems in the industrial sector. The acquisition extends the Company’s reach into the industrial sector, with new exposure to the power generation, food processing, manufacturing, and metal markets in Kentucky, Illinois and Michigan.

See Note 3 – Acquisitions in the accompanying notes to the Company’s consolidated financial statements for further information on the Kent Island and the Consolidated Mechanical transactions.

Customers

The Company’s customer base primarily consists of building owners and their third-party representatives, general contractors and construction managers. As stated previously, one of the Company’s strategic goals relate to the continued focus on the growth of its direct relationships with building owners. The Company believes that its ODR service offerings provide a distribution channel through which it can continue to deliver an expanded offering of value-added services direct to building owners that further reinforces its value proposition and differentiated capabilities. The Company’s team members uniquely combine engineering expertise with field installation skills to provide custom solutions that leverage its full life-cycle capabilities, which allows it to address both the operational and capital projects needs of its customers. This also positions the Company to deliver additional products and services in the future. The Company maintains hundreds of building owner relationships through its contracts for program management, maintenance and critical system repairs. For the years ended December 31, 2024, 2023 and 2022, no ODR customer accounted for more than 10% of the Company’s consolidated revenue.

The Company believes it has strong relationships with many national commercial general contractors and construction managers. As one of its core risk management processes, the Company is selective in choosing to work with general contractors and construction managers that have similar core values, that have a solid payment history, that have experienced and available project management labor, and that value the Company’s services and reputation. Most of the Company’s branches also maintain strong relationships with local and regional general contractors and construction managers that fit its selection criteria. For the years ended December 31, 2024 and 2023, no GCR segment customer accounted for more than 10% of the Company’s consolidated revenue. For the year ended December 31, 2022, one GCR segment customer accounted for approximately 11% of consolidated total revenue.

ODR and GCR Backlog

The Company refers to its estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue it had recognized under such contracts, as “backlog.” Backlog includes unexercised contract options. The Company’s backlog includes projects that have a written award, a letter of intent, a notice to proceed or an agreed upon work order to perform work on mutually accepted terms and conditions. Additionally, the difference between the Company’s backlog and remaining performance obligations is due to the portion of unexercised contract options that are excluded, under certain contract types, from the Company’s remaining performance obligations as these contracts can be canceled for convenience at any time by the Company or the customer without considerable cost incurred by the customer. In addition to backlog, the Company has a substantial amount of contracts with short lead times that book-and-bill within the same reporting period and are not included in backlog. Additional information related to the Company’s remaining performance obligations is provided in Note 4 — Revenue from Contracts with Customers in the accompanying notes to its consolidated financial statements. See also Item 1A. “Risk Factors — Our contract backlog is subject to unexpected adjustments and cancellations and could be an uncertain indicator of our future earnings.”

The Company’s ODR backlog was $225.3 million and $147.0 million as of December 31, 2024 and 2023, respectively. These amounts reflect unrecognized revenue expected to be recognized over the remaining terms of the Company’s service contracts and projects. Based on historical trends, the Company estimates that 86% of its ODR backlog as of December 31, 2024 will be recognized as revenue during 2025. The Company believes its ODR backlog increased due to its continued focus on the accelerated growth of its ODR business.

The Company’s GCR backlog was $140.0 million and $186.9 million as of December 31, 2024 and 2023, respectively. Projects are brought into backlog once the Company has been provided a written confirmation of award and the contract value has been established. At any point in time, the Company has a substantial volume of projects that are specifically identified and advanced in negotiations and/or documentation, however those projects are not booked as backlog until the Company has received written confirmation from the owner or the general contractor/construction manager of their intention to award the Company the contract and they have directed the Company to begin engineering, designing, incurring construction labor costs or procuring needed equipment and material. The Company’s GCR projects tend to be built over a 12- to 24-month schedule depending upon scope and complexity. Most major projects have a preconstruction planning phase which may require months of planning before actual construction commences. The Company is occasionally employed to deliver a “fast-track” project, where construction commences as the preconstruction planning work continues. As work on the Company’s projects progress, it increases or decreases backlog to take into account its estimate of the effects of changes in estimated quantities, changes in conditions, change orders and other variations from initially anticipated contract revenue, and the percentage of completion of the Company’s work on the projects. Based on historical trends, the Company currently estimates that 72% of its GCR backlog as of December 31, 2024 will be recognized as revenue during 2025. Additionally, the reduction in GCR backlog has been intentional as the Company continues to focus on higher margin projects than it has done historically, as well as its focus on smaller, higher margin owner direct projects.

Competition

The mechanical, plumbing, electrical, and maintenance industry is highly competitive and fragmented, with a range of participants including small regional businesses, large national companies, and specialized subcontractors. The geographic markets in which the Company competes has numerous companies that provide similar services. The Company competes on various factors, including; cost efficiency, reputation and quality of service, technical expertise and innovation, geographic reach and scale, knowledge of local markets and conditions, financial strength, surety bonding capacity, availability and experience of craft labor, and customer relationships. The Company’s competitors range from smaller local businesses offering highly specialized services to large multinational corporations with broader service offerings. While some competitors may have greater financial resources or local market presence, the Company believes its comprehensive services portfolio, commitment to safety and quality, and focus on customer satisfaction position it to compete effectively. Additionally, the mechanical service industry is also subject to evolving trends such as increased demand for energy-efficient systems, sustainability initiatives, and advancements in automation. Adapting to these trends remains critical to maintaining a competitive advantage.

Materials and Equipment

The Company’s operations rely on a wide range of materials and equipment essential for providing mechanical contracting services. The Company procures materials and equipment from a network of suppliers and manufacturers. The Company’s supply chain strategy emphasizes maintaining strong relationships with key vendors to ensure consistent quality and timely delivery. While we source the majority of materials domestically, some components are sourced internationally, subject to import regulations and tariffs. The cost and availability of materials and equipment can fluctuate based on market conditions, global supply chain disruptions, and changes in commodity pricing. The Company actively monitors these factors and employs strategies such as effectively managing its business through enhanced labor planning and project scheduling, increased pricing to the extent contractually permitted, and by leveraging its relationships with its suppliers and customers. The Company ensures that all materials and equipment meet applicable environmental and regulatory requirements. Additionally, the Company is increasingly incorporating sustainable and energy efficient materials into its projects to meet customer demands and comply with evolving industry standards. See Item 1A. “Risk Factors — An increase in the cost or the availability of materials and commodities could affect our profitability.” in this Annual Report on Form 10-K.

In February 2025, the United States government announced a number of tariffs on imports, including imports on steel and aluminum. Increased costs for imported steel and aluminum products have led domestic sellers to respond with market-based increases to prices for such inputs as well. These tariffs, along with any additional tariffs or trade restrictions that may be implemented by the United States or other countries, could result in further increased costs, shifts in competitive positions and a decreased supply of steel, resins and aluminum as well as additional imported components and materials. The Company’s ODR segment focus often allows for these increased costs to be passed onto the customer due to the short sales cycle; however, the Company may not be able to pass certain price increases on to its customers and may not be able to secure adequate alternative sources of materials on a timely basis. While retaliatory tariffs imposed by other countries on the United States have not yet had a significant impact, the Company cannot predict further developments. At this time, it is difficult to accurately measure the impact these tariffs, or potential future tariffs, will have on the Company.

Human Capital

To ensure that the Company is well positioned to provide innovative system solutions and reliable services in a safe, efficient and responsible manner, the Company seeks to employ and retain a team of highly dedicated and accomplished people who genuinely care about the success of the Company. Creating an engaging workplace environment that provides for competitive pay and benefits, attractive career development opportunities, and a collaborative, respectful culture further enables the Company to achieve continued success.

Team members. As of December 31, 2024, the Company had approximately 1,400 team members, including approximately 500 full-time salaried team members who support its customers directly and indirectly, such as project managers, account managers, engineers and superintendents, and approximately 900 technician and craft team members, some of whom are represented by various labor unions. The Company believes it has a good relationship with its team members and has developed several strong partnerships with local unions to have access to an experienced, talented technician and craft workforce.

Core Values and Core Purpose. From the technicians in the field to the management team, the Company focuses on caring for its people. The Company’s core purpose “is to create great opportunities for people.” The Company has implemented internal development programs, which allow it to attract, develop and retain talent and emphasize the importance of promoting from within. The Company believes its core values reflect who it is. The Company cares about its people and believes its approach provides a competitive advantage. Since 2021, the Company has reduced its salaried attrition rate by 43% through the effective implementation of its human capital strategies.

The Company’s culture is driven by its core values:

• We CARE: We care about safety and having our team members return home injury-free every day. We care about the environment, which is why we explore the life-cycle and total cost of ownership on every project. We care about our communities, which is why we support social and community-based programs and encourage our team members to make a difference by giving back.
• We Act with INTEGRITY: Our business is driven by doing the right thing for our team members and customers. We pride ourselves on delivering on our commitments.
• We Are INNOVATIVE: We are a collaborative team with diverse technical expertise that equips us to tackle our customers’ toughest challenges. Our culture supports and encourages our team members to speak up to express their ideas, track future trends, and breathe life into new concepts, all aimed at improving our company and making our customers’ lives easier. By creating an environment of continuous learning, we empower our people with the proper training and competencies to deliver innovative solutions tailored to address our customers’ evolving needs.
• We Are ACCOUNTABLE: We are a company with drive and discipline. We set goals and hold each other responsible for the outcomes. We utilize the Entrepreneurial Operating System (“EOS”) as our way of managing and leading the organization for top performance. The EOS assists our management team by clarifying, simplifying and achieving our business vision through providing a structured approach to management of operations and ensuring that everyone in the Company is aligned and working towards the same goals.

The Company believes its team members are essential to its continued success and the Company seeks to provide every team member with the foundation and environment needed to achieve the team members’ goals. This objective begins with the Company's commitment to inclusion. We CARE, one of the Company’s core values, is the foundation of its efforts to create a fair and inclusive organization. Building a culture where all of its team members feel a sense of belonging is important to the Company.

In addition, the Company screens leadership hires and measures team member performance against these core values, and regularly measures team member engagement against these values through the Company’s annual team member engagement survey. The Company’s “We Care” survey, which has been issued for more than twenty years, provides leadership with insights, including constructive ideas on how to improve the overall business for those who work for it. In 2024, the Company was recognized as one of America’s “Most Loved Workplaces,” published by Newsweek Magazine and certified by the Best Practice Institute. Additionally, for the second year in a row, the Company was recognized as one of Forbes’ “Most Successful Small Companies” (in 2024 and 2025).

Training and Team Member Development. Investment in continuous learning is essential to providing industry-leading expertise and service to the Company’s customers, continuous improvement across its organization, and meaningful career development opportunities for its people. From in-person to online courses, formalized and other specialized training, the Company’s team members benefit from opportunities to strengthen their leadership and management competencies, improve communication and interpersonal skills, and advance their technical proficiency. The Company’s team members have access to resources that include a robust learning management system that provides company-wide access for team members to a number of online learning modules and support tools. As a result of its efforts, the Company was recognized as one of the top training organizations in the world earning a Training APEX Award from Training magazine for its third consecutive year (in 2023, 2024 and 2025). Additionally, the Company was recognized in 2024 and 2025 as a winner of the Association of Talent Development’s BEST award, which honors organizations that demonstrate enterprise-wide success as a result of employee talent development. The Company’s team members see the impact of these programs, and in 2023 and 2024, its training programs averaged a participant Net Promoter Score of over 85%. The Company has invested in additional training to support those team members directly working in customer-facing roles across the Company, such as account management training, as it aims to grow its ODR business.

Culture of Belonging. The Company is committed to creating and supporting a fair and inclusive environment for its team members, We Care culture and industry as a whole. The Company actively seeks to foster an environment where every team member’s voice is heard and every team member can reach their full potential. The Company practices its commitment through its core values, selection, development and training, which extends to its senior leadership and Board of Directors. The Company understands that inclusivity is truly a competitive advantage that helps drive growth and innovation.

Embrace Forum. The Company formed the Embrace Forum to continue to evolve its commitment to a culture of belonging. This forum is composed of team members and leaders across the company who have made it their mission to maximize the potential of the Company’s team members by creating great opportunities through a fair and inclusive environment. The Embrace Forum focuses on creating a culture of belonging, community and supporting employee resource groups (“ERGs”).

The Company offers all of its team members the opportunity to join ERGs. These groups foster professional development, social connectivity, and celebrate inclusivity throughout the Company. Each year, new ERGs are evaluated for consideration. Currently, there are four active ERGs at the Company:

• Women in Construction and Service (“WICS”). The Company is committed to promoting and supporting women within its organization throughout their career, including to take on leadership roles, and helping encourage other women to join its industry as a whole. To support this initiative, the Company created the WICS ERG with a vision to create a culturally agile community that respects and empowers women within the Company and industry.
• Unidos. Unidos is an ERG that was created to empower and amplify the Hispanic culture within the Company. The mission of this ERG is to create a supportive environment for Hispanic team members and their allies and provide a more inclusive environment where everyone feels safe, respected and valued.
• Hearts & Hands. Hearts & Hands is an ERG with the core purpose of providing opportunities and encouraging team members to make a difference by giving back to communities in which the Company has an operating footprint.
• Veterans. The Veterans ERG aims to offer resources, foster camaraderie, and promote understanding among Company team members who have served in the military and those who are committed to supporting them.

In addition, to help recruit the next generation of diverse industry leaders, the Company is actively involved with the ACE Mentor Program of America, Inc. (“ACE”). ACE helps mentor high school students and inspires them to pursue careers in design and construction. It is the construction industry’s fastest-growing high school mentoring program, reaching over 8,000 students annually.

Benefits & Wellness. The Company focuses on the most crucial component for its success; its team members. The Company appreciates the fact that it owes its 120+ year existence to team members who work hard to help the Company prosper.

As such, the Company has committed itself to the health, safety and well-being of its team members and their families. One of the ways the Company shows its commitment is through offering competitive team member compensation and benefits packages, specifically designed to meet the unique needs of each individual in its organization, which include:

• Health and Welfare Plans. All full-time team members 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 spending accounts that include employer contributions.
• Retirement Savings. The Company helps provide its team members with financial security by offering a 401(k) Savings Plan, which includes company matching contributions, and an Employee Stock Purchase Plan.
• Employee Assistance Programs. Through the Employee Assistance Program, the Company offers its team members, and their dependents or household members, access to services and counseling on a variety of personal, professional, legal, and financial matters, at no cost.
• Work/Life Programs. Consists of various activities intended to inspire the Company’s team members towards healthy living through personal accountability.

Safety Culture. Safety is integral to the Company’s unique culture and core values. The Company cares about its team members and their families, and it holds each other accountable for working safely. The Company’s safety culture is based on its “Hearts and Minds Commitment to Safety” program, established in 2013 by its senior staff and field professionals via its Hearts and Minds Forum. The Company’s Hearts and Minds Forum asks its team members to take direct responsibility for eliminating and preventing all incidents and injuries at home and in the workplace, which is done by:

• Hiring the Right People. Hiring qualified team members who share its core values.
• Knowing the Details. Thorough planning and having acute awareness of present surroundings, which aids in executing work safely.
• Engaging at All Levels. Setting a great example of completing all tasks safely, at work and at home, by everyone from the management team to craft professionals.
• Mentoring and Coaching. Acting as a mentor and coach to show team members how to practice good safety behavior.

In 2020, this program helped earn the Company’s Ohio business unit the highest honor for which Occupational Safety and Health Administration (“OSHA”) can name a company; OSHA-Voluntary Protection Programs Star Site. This was the first time a union mechanical contractor has earned such an honor in the United States. The Company strives to achieve this honor at its other business units.

Seasonality

Severe weather can impact the Company’s operations. In the northern climates where it operates, and to a lesser extent in the southern climates as well, severe winters can slow the Company’s productivity on construction projects, which shifts revenue and gross profit recognition to a later period. The Company’s maintenance operations may also be impacted by mild or severe weather. Mild weather tends to reduce demand for the Company’s maintenance services, whereas severe weather may increase the demand for its maintenance and time-and-materials services.

Government and Environmental Regulations

The Company is subject to various federal, state and local laws and regulations relating to the environment, including those relating to discharges to air, water and land, the handling and disposal of solid and hazardous waste, the handling of underground storage tanks and the cleanup of properties affected by hazardous substances. The Company is also subject to compliance with numerous other laws and regulations of federal, state, local agencies, and authorities, including those relating to workplace safety, wage and hour, and other labor issues (including the requirements of the Occupational Safety and Health Act and comparable state laws), immigration controls, vehicle and equipment operations and other aspects of its business. In addition, a relatively limited number of the Company’s construction contracts are entered into with public authorities, and these contracts frequently impose additional requirements, including requirements regarding labor relations and subcontracting with designated classes of disadvantaged businesses. A large portion of the Company’s business uses labor that is provided under collective bargaining agreements. As such, the Company is subject to federal laws and regulations related to unionized labor and collective bargaining (including the National Labor Relations Act).

The Company continually monitors its compliance with these laws, regulations and other requirements. While compliance with existing laws, regulations and other requirements has not materially adversely affected the Company’s operations in the past, and the Company is not aware of any proposed requirements that it anticipates will have a material impact on its operations, there can be no assurance that these requirements will not change or that compliance will not otherwise adversely affect the Company’s operations in the future. In addition, while the Company typically passes any costs of compliance on to its customers under the applicable project agreement, either directly or as part of its estimate, depending on the type of contract, there can be no assurance that the Company will not incur compliance expenses in the future that materially adversely affect its results of operations. Furthermore, certain environmental laws impose substantial penalties for non-compliance and other laws, such as the federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), and comparable state laws, which impose strict, retroactive, joint and several liability upon persons that contribute to the release of a “hazardous substance” into the environment. These persons include the owner or operator of the site where the release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the site.

Climate Change and Sustainability

The Company recognizes its environmental and societal responsibilities and is committed to sustainability and to improving its environmental footprint as well as operating its business in a manner that seeks to protect the health and safety of the Company’s team members and customers, as well as the public. The Company’s focus on environmental stewardship and improving productivity drives not only its efforts to become more energy efficient but also improvements in the Company’s customers’ impact on the climate. Replacing an aging building’s existing systems with modern, energy-efficient systems significantly reduces a building’s energy consumption and carbon footprint while improving cost, air quality and overall system effectiveness.

The Company is subject to the requirements of numerous federal, state and local laws, regulations and rules that promote the protection of the environment. While capital expenditures or operating costs for environmental compliance cannot be predicted with certainty, the Company does not currently anticipate that they will have a material effect on its capital expenditures or competitive position in the short term.

Risks Related to Our Business and Industry

Intense competition in our industry could reduce our market share and profit.

The mechanical, plumbing, electrical, and maintenance industry is highly competitive and fragmented, with a range of participants including small regional businesses, large national companies, and specialized subcontractors. The geographic markets in which we compete in have numerous companies that provide similar services. We compete on the basis of our technical expertise and experience, financial and operational resources, industry reputation and dependability. While we believe our customers consider a number of these factors in awarding available contracts, price is often the principal factor in determining which contractor is selected, especially on smaller, less complex projects. As such, smaller competitors are sometimes able to win bids for such projects based on price alone due to their lower cost and financial return requirements. We expect competition to remain intense for the foreseeable future, presenting us with significant challenges in our ability to maintain strong growth rates and acceptable profit margins. We also expect competition from the in-house service organizations of our customers who have employees who perform service and maintenance work similar to the services we provide as part of our ODR offering. Vertical consolidation is also expected to intensify competition in the industry. We can offer no assurance that our existing or prospective customers will continue to outsource specialty contracting services in the future. In addition, new and emerging technologies and services are expected to significantly impact the industry in coming years. If we are unable to meet these competitive challenges, we could lose market share to our competitors and experience an overall reduction in our profits. In addition, our profitability would be impaired if we have to reduce our prices to remain competitive.

If we do not effectively manage the size and cost of our operations, our existing infrastructure may become either strained or overly-burdened, and we may be unable to increase revenue growth.

The growth we have experienced in the past, and that we may experience in the future, may provide challenges to our organization, requiring us to expand our personnel and operations. Future growth, whether organic or through acquisitions, may strain our infrastructure, operations and other managerial and operating resources. We have also experienced severe constriction in the markets in which we operated in the past and, as a result, in our operating requirements. Failing to maintain the appropriate cost structure for a particular economic cycle may result in us incurring costs that affect our profitability. If our business resources become strained or overly-burdensome, our earnings may be adversely affected and we may be unable to increase revenue growth. Further, we may undertake contractual commitments that exceed our labor resources, which could also adversely affect our earnings and ability to increase revenue growth.

Failure to achieve and maintain a high level of building systems solutions in our ODR segment could damage our reputation with customers and negatively impact our results.

As our ODR business continues to expand, our ability to provide building systems solutions at a very high level is very important to the continued success of our business. Additionally, quality issues could harm customer confidence in our company and our brands. If our building systems solutions offerings do not meet applicable safety standards or our customers’ expectations regarding quality, safety or performance, we could experience lost sales and increased costs and we could be exposed to legal, financial and reputational risks. In addition, when our building systems solutions fail to perform as expected, we could be exposed to warranty, product liability, personal injury and other claims.

Our contract backlog is subject to unexpected adjustments and cancellations and could be an uncertain indicator of our future earnings.

We cannot guarantee that the revenue projected in our contract backlog will be realized or, if realized, will be profitable. Projects reflected in the contract backlog may be affected by project cancellations, scope adjustments, time extensions or other changes. Such changes may materially and adversely affect the revenue and profit we ultimately realize on these projects.

Since we bear the risk of cost overruns in most of our contracts, we may experience reduced profits or, in some cases, losses, if costs increase above estimates.

Our contract prices are established largely upon estimates and assumptions of our projected costs, including assumptions about future economic conditions; prices, including commodities prices; availability of labor; the costs of providing labor, equipment, and materials; and other factors outside of our control. If our estimates or assumptions prove to be inaccurate, due to changing circumstances or our failure to successfully execute the work, cost overruns may occur and we could experience reduced profits or a loss for affected projects. For instance, unanticipated technical problems may arise; we could have difficulty obtaining permits or approvals; local laws, labor costs or labor conditions could change; bad weather could delay construction; prices of raw materials could increase; suppliers or subcontractors may fail to perform as expected; or site conditions may be different than originally anticipated. We are also exposed to increases in energy prices. Additionally, in certain circumstances, we guarantee project completion or the achievement of certain acceptance and performance testing levels by a scheduled date. Failure to meet schedule or performance requirements typically results in additional costs to us, and in some cases may also create liability for consequential and liquidated damages. Performance problems for existing and future projects could also cause our actual results of operations to differ materially from those anticipated and could damage our reputation within the industry and our customer base.

In addition, the costs incurred and gross profit realized on our contracts can vary, sometimes substantially, from our original projections due to a variety of factors, including, but not limited to:

• on-site conditions that differ from those described in the original bid or contract;
• failure to include required materials, equipment, or work in a bid, or the failure to properly estimate the quantities or costs needed to complete a lump sum or guaranteed maximum price contract;
• contract or project modifications creating unanticipated costs not covered by change orders;
• failure by the customer, owner or general contractor to properly approve and authorize change orders for work that is required and as a result, the inability to bill and collect for the value of the work performed;
• failure by suppliers, vendors, subcontractors, designers, engineers, consultants, joint venture partners or customers to perform their obligations;
• delays in quickly identifying and taking measures to address issues which arise during contract execution;
• changes in availability, proximity and costs of materials and equipment, including pipe, sheet metal, other construction materials and mechanical, electrical and plumbing equipment;
• claims or demands from third parties for alleged damages arising from the design, construction or use and operation of a project of which our work is part;
• difficulties in obtaining required governmental permits or approvals;
• availability and skill level of workers in the geographic location of a project;
• citations issued by any governmental authority, including OSHA;
• unexpected labor conditions, shortages, strikes or work stoppages in general causing delays in completion, or acceleration of the contracted work to maintain milestone completion dates, which could cause losses due to not meeting estimated production targets;
• installation productivity rates different than the rate that was estimated;
• changes in applicable tariffs, laws and regulations;
• delays caused by weather conditions;
• fraud, theft or other improper activities by suppliers, vendors, subcontractors, designers, engineers, consultants, joint venture partners, customers or our own personnel; and
• mechanical or performance problems with equipment.

Many of our customer contracts contain provisions that purport to shift some or all of the above risks from the customer to us, even in cases where the customer is partly at fault. We are not always able to shift this risk to subcontractors. Our experience has been that customers are willing to negotiate equitable adjustments in the contract compensation or completion time provisions if unexpected circumstances arise. However, customers may seek to impose contractual risk-shifting provisions more aggressively, which could increase risks and adversely affect our financial position, results of operations and cash flows.

Our failure to obtain new agreements and renew existing agreements could have a material adverse effect on our business, financial condition and results of operations.

Our business depends on our ability to win new agreements and renew existing agreements with customers. Agreement proposals and negotiations can be complex and frequently involve a lengthy sales and selection process, which is affected by a number of factors. These factors include market conditions, the timing of renewals, the pricing of these arrangements and other matters that are outside of our control. If negative market conditions arise, or we encounter other difficulties in obtaining new or repeat work, we may not be able to pursue certain projects or work, which could have a material adverse effect on our business, financial condition and results of operations.

Timing of the award and performance of new contracts could have an adverse effect on our operating results and cash flow.

The timing of project awards is unpredictable and outside of our control. Project awards often involve complex and lengthy negotiations and competitive bidding processes. These processes can be impacted by a wide variety of factors, including a customer’s decision to not proceed with the development of a project, governmental approvals, financing contingencies, commodity prices, environmental conditions, and overall market and economic conditions. We may not win contracts that we have bid upon for any number of reasons, including price, a customer’s perception of our ability to perform, a competitor’s relationships and/or perceived technology advantages held by others. Many of our competitors may be more inclined to take greater or unusual risks or accept terms and conditions in a contract that we might not deem acceptable. Despite a significant portion of our project revenue being generated from smaller, more risk averse contracts, our results of operations may fluctuate quarterly and annually depending on whether, and when, large project awards occur, as well as the commencement and progress of work under large contracts already awarded. As a result, we are subject to the risk of losing new awards to competitors or the risk that revenue may not be derived from awarded projects as quickly as anticipated.

The uncertainty of the timing of project awards may also present difficulties in matching the size of our work crews with project needs. In some cases, we may maintain and bear the cost of more ready work crews than are currently required in anticipation of future needs for existing contracts or expected future contracts. If a project is delayed or an expected project award is not received, we would incur costs that could have a material adverse effect on our anticipated profit.

In addition, the timing of the revenue, earnings and cash flows from our contracts in backlog could be delayed by a number of factors, including adverse weather conditions; other subcontractors delaying the progression of proceeding work; delays in receiving material and equipment from suppliers and services from subcontractors; and changes in the scope of work to be performed. Such delays, if they occur, could have material and adverse effects on our operating results for current and future periods until the affected contracts are completed.

We may incur significant costs in performing our work in excess of the original project scope and contract amount without having an approved change order.

After the award of a contract, we may perform additional work that was not contemplated in our original contract price, at the request or direction of the customer, without the benefit of an approved change order. Our contracts generally afford the customer the right to order such changed or additional work, and typically require the customer to compensate us for the additional work. If we are unable to successfully negotiate a change order, or fail to obtain adequate compensation for these matters, we could be required to record in the current period an adjustment to revenue and profit recognized in prior periods. Such adjustments, if substantial, could have a material adverse effect on our financial position, results of operations and cash flows.

Our failure to adequately recover on claims brought by us against contractors, project owners or other project participants for additional contract costs could have a negative impact on our results of operations and financial condition, liquidity and on our credit facilities.

In certain circumstances, we assert or have asserted claims against project contractors, owners, engineers, consultants, subcontractors or others involved in a project for additional costs exceeding the contract price or for amounts not included in the original contract price. These types of claims occur due to matters such as delays, inefficiencies or errors caused by others or changes from the initial project scope, all of which may result in additional costs. Often, these claims can be the subject of lengthy negotiations, arbitration or even litigation proceedings, and it is difficult to accurately predict when and on what terms these claims will be ultimately resolved.

The potential impact of recoveries for claims may be material in future periods when they, or a portion of them, become probable and estimable or are settled and therefore these claims have the ability to negatively impact our results of operations and financial condition. For example, we could have estimated and reported a profit on a contract over several periods and later determined, that all or a portion of such previously estimated and reported profits were overstated due to the results of the settlement of a claim. If this occurs, the full aggregate amount of the overstatement would be reported for the period in which such determination is made, thereby offsetting all or a portion of any profits from other contracts that would be reported in such period, or even resulting in a loss being reported for such period. On a historical basis and in accordance with generally accepted accounting principles in the United States of America, we have used a detailed process in estimating and accounting for these claims and we believe that we have typically made reliable estimates of such claims. However, given the uncertainties associated with these types of claims, it is possible for actual recoveries to materially and adversely vary from estimates previously made, which may result in reductions or reversals of previously recorded revenue and profits. We could also recognize additional revenue and profits when the final settlements exceed our recorded estimates.

In addition, when these types of claims are made, we may use or have used working capital to cover cost overruns pending the resolution of the relevant claims and may incur additional costs when pursuing such potential recoveries. A failure to recover on these types of claims promptly and fully could have a negative impact on our financial position, results of operations, cash flows and liquidity. Moreover, our use of working capital to cover cost overruns related to pending claims may impact our ability to meet our credit agreement covenants or limit the use of our credit agreements. If we default under our credit agreements, it could result in, among other things, us no longer being entitled to borrow under one or more of the credit agreements, acceleration of the maturity of outstanding indebtedness under the agreements, foreclosure on collateral securing the obligations under the agreements or require us to enter into amendments and/or waivers to those credit agreements that may place additional requirements on us and that cost us additional amounts payable to our lenders.

We place significant decision making powers with our business units’ management, which presents certain risks that may cause the operating results of individual branches to vary.

We operate from various locations across the eastern United States, supported by corporate executives and services, with local business unit management retaining responsibility for day-to-day operations and adherence to applicable laws. We believe that our practice of placing significant decision making powers with local management is important to our successful growth and allows us to be responsive to opportunities and to our customers’ needs. However, this practice can make it difficult to coordinate procedures across our operations and presents certain risks, including the risk that we may be slower or less effective in our attempts to identify or react to problems affecting an important business issue than we would under a more centralized structure, or that we would be slower to identify a misalignment between a subsidiary’s and our overall business strategy. If a subsidiary location fails to follow our compliance policies, we could be made party to a contract, arrangement or situation with exposure to large liabilities or that has less advantageous terms than is typically found across the markets in which we operate. Likewise, inconsistent implementation of corporate strategy and policies at the local level could materially and adversely affect our financial position, results of operations, cash flows and prospects.

The operating results of an individual location may differ from those of another location for a variety of reasons, including market size, local customer base, regional construction practices, competitive landscape, regulatory requirements, state and local laws and local economic conditions. As a result, certain of our locations may experience higher or lower levels of profitability and growth than our other locations.

Acquisitions, divestitures, and other strategic transactions could fail to achieve financial or strategic objectives, disrupt our ongoing business, and adversely impact our results of operations.

We have been pursued and may pursue in the future selective acquisitions to expand, complement, or diversify our business as growing by acquisition is part of our stated growth strategy. We cannot provide assurances that we will be able to identify suitable acquisition targets or that we will be able to consummate acquisitions on terms and conditions acceptable to us, or that the acquired businesses will be profitable. Acquisitions may expose us to additional business risks different than those we have traditionally experienced. We also may encounter difficulties or failure to integrate acquired businesses and successfully managing the growth we expect to experience from these acquisitions.

We may choose to finance future acquisitions with debt, equity, cash or a combination of the three. Future acquisitions could dilute earnings. To the extent we succeed in making acquisitions, a number of risks may result, including:

• the transaction may not effectively advance our business strategy, and its anticipated benefits may never materialize;
• the assumption of material liabilities or inability to realize the cost savings or other financial benefits anticipated prior to acquisition (including environmental-related costs and multiemployer pension plans) through failure of due diligence to uncover situations that could result in legal exposure or to quantify the true liability exposure from known risks;
• the assumption of multiemployer pension plans (“MEPP”) liability in the event of an acquisition with existing unions, and an increased exposure to challenges to the structure of our union and non-union subsidiaries and operations if an open shop business is acquired; and
• any additional indebtedness incurred in connection with an acquisition may impact our financial position, results of operations, and cash flows.

Furthermore, the costs associated with a failed acquisition or attempted acquisition transaction could have an adverse effect on our financial position, results of operations and cash flows.

Our failure to successfully integrate acquisitions could adversely affect our financial results.

The success of our stated growth strategy depends on our ability to realize the anticipated benefits from the acquired businesses, such as the expansion of our existing operations and elimination of redundant costs. To realize these benefits, we must successfully integrate the operations of the acquired businesses with our existing operations. Integrating acquired businesses involves a number of operational challenges and risks, including:

• diversion of management’s attention from our existing business;
• inability to successfully convert acquisitions to our operational business strategy;
• difficulties in the retention of management and other key employees, the assimilation of different cultures and practices, broad and geographically dispersed personnel and operations, and the retention of customers or key employees of an acquired business could negatively impact our business and the acquired business;
• unanticipated issues in integrating an acquired business’s accounting, information technology, human resources, and other administrative systems may fail to permit effective management and expense reduction; and
• the risk of additional financial and accounting challenges and complexities in areas such as tax planning, treasury management, financial reporting and internal controls.

These factors could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy, which could adversely affect our results of operations and financial position. Additionally, any impairment of goodwill or other intangible assets as a result of our failure to successfully integrate acquisitions could adversely affect our results of operations and financial position.

Design/Build and Design/Assist contracts subject us to the risks of design errors and omissions.

Design/Build projects provide the customer with a single point of responsibility for both design and construction. When we are awarded these projects, we typically perform the design and engineering work in-house. On other projects, we are not the designer, but provide assistance directly to the project design team. In the event that a design error or omission by us causes damage, there is risk that we, our subcontractors or the respective professional liability or errors and omissions insurance would not be able to absorb the liability. Any liability resulting from an asserted design defect with respect to our projects may have a material adverse effect on our financial position, results of operations and cash flows.

If we experience delays and/or defaults in customer payments, we could be unable to recover all expenditures.

Due to the nature of our contracts, we sometimes commit resources to projects prior to receiving payments from the customers in amounts sufficient to cover expenditures on projects as they are incurred. Delays in customer payments may require us to make a working capital investment. If a customer defaults in making their payments on a project to which we have devoted resources, it could have a material negative effect on our financial position, results of operations and cash flows.

Unsatisfactory safety performance may subject us to penalties, affect customer relationships, result in higher operating costs, negatively impact employee morale and result in higher employee turnover.

Our work is conducted at offices the Company leases, as well as a variety of sites including construction sites and industrial facilities. Each location is subject to numerous health and safety risks, including electrocutions, fires, explosions, mechanical failures, exposure to hazardous materials, weather-related incidents, motor vehicle and transportation accidents and damage to equipment. In addition, we lease a sizeable fleet of vehicles operated by our employees, and many of our employees operate their personal vehicles in the course and scope of their employment, traveling to and from the sites and our facilities. 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 and, in extreme cases, criminal liability. While we have taken what we believe are appropriate precautions to minimize health and safety risks, we have experienced serious incidents in the past and may experience additional incidents in the future. Serious accidents may subject us to penalties, civil litigation or criminal prosecution. Claims for damages to persons, including claims for bodily injury or loss of life, could result in significant costs and liabilities, which could adversely affect our financial position, results of operations and cash flows. In addition, like other companies in our industry, we track our injury history in the form of an Experience Modification Rate (“EMR”). In the event that the EMR associated with certain of our operating units exceeds the minimum threshold set by customers, we may be unable to pursue certain projects. Poor safety performance could also jeopardize our relationships with our customers and harm our reputation.

Our inability to properly utilize our workforce could have a negative impact on our profitability.

The extent to which we utilize our workforce affects our profitability. Underutilizing our workforce could result in lower gross margins and, consequently, a decrease in our short-term profitability. On the other hand, overutilization of our workforce could negatively impact safety, employee satisfaction, attrition, and project execution, leading to a potential decline in future project awards. The utilization of our workforce is impacted by numerous factors, including:

• our estimates of headcount requirements and our ability to manage attrition;
• efficiency in scheduling projects and our ability to minimize downtime between project assignments;
• productivity;
• labor disputes; and
• availability of skilled labor at any given time.

Our business has union and open shop operations, subjecting the business to risk for labor disputes.

We have separate subsidiary employers that have union and non-union operations. There is a risk that our corporate structure and operations in this regard could be challenged by one or more of the unions to which the employees belong. An adverse claim or judgment resulting from such a challenge could have a material adverse effect on our financial position, results of operations and cash flows.

Strikes or work stoppages could have a negative impact on our operations and results.

We are a party to collective bargaining agreements covering a majority of our craft workforce. Although strikes, work stoppages and other labor disputes have not had a significant impact on our operations or results of operations in the recent past, any such labor actions, or our inability to renew the collective bargaining agreements, could materially and adversely impact our financial position, results of operations and cash flows if they occur in the future.

Our business may be negatively affected by our failure to properly execute our business strategy.

In order to maintain and grow our business, we must make strategic decisions about our current and future business plans and effectively execute upon those plans. Our principal focus over the past few years, and a focus that we plan to continue in coming years, is the accelerated growth of our ODR segment, which includes maintenance services, small projects, building controls installation and service, building environment management and performance services, and other project opportunities performed direct for building owners. We are focused on expanding the number and breadth of owner relationships that we serve on a direct basis and to leverage these expanded owner-direct relationships to deliver a broad suite of services. We have made substantial investments to expand our ODR segment by increasing the value we can offer to service and maintenance customers. We continue to actively concentrate managerial and sales resources on training and hiring experienced employees to sell and profitably perform ODR work. With our ODR-centric focus, we’ve lessened, and continue to lessen, our resources allocated to our GCR segment and continue to limit the GCR-related work we pursue. Although we believe our ODR-centric focus addresses the needs of our business and its long-term objectives, our strategy is based on certain assumptions and forecasts, which are subject to risks and uncertainties, including whether we have accurately identified the issues, targeted the appropriate market customers, and executed our strategic efforts at the appropriate scale and scope, as well as continuing to do so. Consequently, the continued business transition to an ODR-centric focus may not be successful in yielding the intended results. Our business and financial results may be adversely impacted if we do not successfully execute our business strategy.

Our success depends upon the continuing contributions of certain key personnel, each of whom would be difficult to replace. If we lose the benefit of the experience, efforts and abilities of one or more of these individuals, our operating results could suffer.

Our continuing success depends on the performance of our management team. We rely on the experience, efforts and abilities of these individuals, each of whom would be difficult to replace. We cannot guarantee the continued employment of any of our key executives who may choose to leave the company for any number of reasons, such as other business opportunities, differing views on strategic direction, etc. If we lose members of our management team, our business, financial position, results of operations, cash flows, and customer base, as well as the market price of our common stock, could be adversely affected.

If we are unable to attract and retain qualified managers, employees, joint venture partners, subcontractors and suppliers, we will be unable to operate efficiently, which could reduce our profitability.

Our business is labor intensive, and many of our operations experience a high rate of employee turnover. It is often difficult to find qualified personnel in certain geographic areas where we operate. Additionally, our business is managed by a small number of key executive and operational officers. Generally, the industry is facing a shortage of trained, skilled, and qualified management, operational, and field personnel. We may be unable to hire and retain the skilled labor force necessary to operate efficiently and to support our growth strategy or to execute our work in backlog. Changes in general or local economic conditions and the resulting impact on the labor market and on our joint venture partners, subcontractors and suppliers, may make it difficult to attract or retain qualified individuals in the geographic areas where we perform our work. Our labor expenses may increase as a result of a shortage in the supply of skilled and other personnel. Labor shortages, increased labor costs or the loss of key personnel could reduce our profitability and negatively impact our business. Further, our relationship with some customers could suffer if we are unable to retain the employees with whom those customers primarily work and have established relationships.

Misconduct by our employees, subcontractors or partners, or our overall failure to comply with laws or regulations could harm our reputation, damage our relationships with customers, reduce our revenue and profits, and subject us to criminal and civil enforcement actions.

Misconduct, fraud, non-compliance with applicable laws and regulations, or other improper activities by one or more of our employees, subcontractors, suppliers or partners could have a significant negative impact on our business and reputation. Examples of such misconduct include employee or subcontractor theft, the failure to comply with safety standards, state-specific laws related to automobile operations (including mobile phone usage), customer requirements, environmental laws, DBE regulatory compliance, and any other applicable laws or regulations. While we take precautions to prevent and detect these activities, such precautions may not be effective and are subject to inherent limitations, including human error and fraud. Our failure to comply with applicable laws or regulations or acts of misconduct could subject us to fines and penalties, harm our reputation, damage relationships with customers, reduce our revenue and profits, and subject us to criminal and civil enforcement actions.

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 or product liability and warranty or other claims against us, as well as 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. 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 and/or retention, could have a material adverse effect on our business, financial condition, and results of operations.

Our dependence on subcontractors and suppliers of equipment and materials could increase our costs and impair our ability to complete contracts on a timely basis or at all, which would adversely affect our profits and cash flow.

We rely heavily on third-party subcontractors to perform some, and often a majority, of the work on many of our contracts. We also rely almost exclusively on third-party suppliers to provide the equipment and materials (including pipe, sheet metal and control systems) for our contracts. If we are unable to retain qualified subcontractors or suppliers, or if our subcontractors or suppliers do not perform as anticipated for any reason, our execution and profitability could be harmed. By contract, we remain liable to our customers for the performance or failures of our subcontractors and suppliers.

We generally do not bid on projects unless we have commitments from suppliers for the materials and equipment and from subcontractors for the services required to complete the projects at prices that have been included in the bid. Thus, to the extent that we cannot obtain commitments from our suppliers for materials and equipment, and from subcontractors for services needed, or to the extent such commitments are on terms that are adverse to the Company, our ability to bid for contracts may be impaired or we may experience reduced profit or a loss on a contract. In addition, if a supplier or subcontractor is unable to deliver materials, equipment or services according to the negotiated terms of a supply/services agreement for any reason, including the deterioration of our financial condition, we may suffer delays and be required to purchase the materials, equipment and services from another source at a higher price or incur other unanticipated costs. This may reduce the profit to be realized, or result in a loss, on a contract.

Recent labor shortages may also lead to higher wages for employees and higher costs to purchase the services of third-party subcontractors. Increases in labor costs, such as increases in minimum wage requirements, wage inflation and/or increased overtime, reduce our profitability and that of our customers. Increases in such labor costs for a prolonged period of time could have a material adverse effect on the company’s financial condition and results of operations

An increase in the cost or the availability of materials and commodities could affect our profitability.

We are exposed to market risks that may cause increases in the cost, or the availability of, materials, equipment and commodities utilized in our operations. We have experienced, and may continue to experience, delays and cost volatility of these items due to supply chain disruptions, inflationary pressures, tariffs, regulatory slowdowns and market disruptions. In addition, our customers’ budgets may be impacted by cost increases and reduced customer spending could lead to fewer project awards and more competition. These costs may be impacted by government regulations, import duties and tariffs, changes in currency exchange rates, general economic conditions and other circumstances beyond our control. We are also exposed to increases in energy prices, particularly as they relate to fuel prices for our fleet vehicles. Although we may attempt to pass on certain of these increased costs to our customers, we may not be able to pass all of these cost increases on to our customers. As a result, our margins may be adversely impacted by such cost increases.

Changes in energy prices may increase our costs, and we may not be able to pass along increased energy costs to our customers.

Energy prices fluctuate based on events outside of our control. We could be adversely affected by limitations on fuel supplies or increases in energy prices that result in higher transportation and equipment operation costs. Although we may be able to pass through the impact of energy price charges to some of our customers, we may not be able to pass all of these cost increases on to our customers. As a result, our margins may be adversely impacted by such cost increases.

We may be unable to identify and contract with qualified DBE contractors to perform as subcontractors.

Certain of our projects include contract clauses requiring DBE participation. The participation clauses may be in the form of a goal or in the form of a minimum amount of work that must be subcontracted to a DBE firm. If we fail to complete these projects with the minimum DBE participation, we may be held responsible for breach of contract, which may include restrictions on our ability to bid on future projects, as well as monetary damages. To the extent we are responsible for monetary damages, the total costs of the project could exceed the original estimates, we could experience reduced profits or a loss for that project, and there could be a material adverse impact to our financial position, results of operations, cash flows and liquidity. Further, if we contract with a DBE contractor that is not properly qualified to perform a commercially useful function, we could be held responsible for violation of federal, state or local laws related to DBE contracting.

Our participation in construction joint ventures exposes us to liability and/or harm to our reputation for failures of our partners.

As part of our business, we are a party to special purpose, project specific joint venture arrangements, pursuant to which we typically jointly bid on and execute particular projects with other companies in the construction industry. Success on these joint projects depends upon the various risks discussed elsewhere in this section and on whether our joint venture partners satisfy their contractual obligations.

We and our joint venture partners are generally jointly and severally liable for all liabilities and obligations of the joint ventures. If a joint venture partner fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming from lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate share of a liability to make up for our partner’s shortfall. Furthermore, if we are unable to adequately address our partner’s performance issues, the customer may terminate the project, which could result in legal liability to us, harm to our reputation and reduction to our profit on a project. We may be the controlling member of a joint venture; however, to the extent we are not controlling, we may have limited control over certain of the decisions made by the controlling member with respect to the work being performed by the joint venture. The other member(s) may not be subject to the same compliance and regulatory requirements. While we have processes and controls intended to mitigate risks associated with our joint ventures, to the extent the controlling member makes decisions that negatively impact the joint venture it could have a material adverse effect on our financial position, results of operations, cash flow and profits.

A significant portion of our business depends on our ability to provide surety bonds. Any difficulties in the financial and surety markets may cause a material adverse effect on our bonding capacity and availability.

Certain of our projects require construction surety bonds (bid, payment, and performance bonds). Historically, surety market conditions have experienced times of difficulty as a result of significant losses incurred by surety companies stemming from macroeconomic trends outside of our control. Consequently, during times when less overall bonding capacity is available in the market, surety terms have become more expensive and more restrictive. We cannot guarantee our ability to maintain a sufficient level of bonding capacity in the future, which could preclude our ability to bid for certain contracts or successfully contract with some customers. Additionally, even if we continue to be able to access bonding capacity to sufficiently bond future work, we may be required to post collateral to secure bonds, which would decrease the liquidity we would have available for other purposes. Our surety providers are under no commitment to guarantee our access to new bonds in the future; thus, our ability to access or increase bonding capacity is at the sole discretion of our surety providers. If our surety companies were to limit or eliminate our access to bonds, the alternatives would include seeking bonding capacity from other surety companies, increasing business with customers that do not require bonds and posting other forms of collateral for project performance, such as letters of credit or cash. We may be unable to secure these alternatives in a timely manner, on acceptable terms, or at all. As such, if we were to experience an interruption or reduction in the availability of bonding capacity, it is likely we would be unable to compete for or work on certain projects.

Our insurance policies against many potential liabilities require high deductibles. Additionally, difficulties in the insurance markets may adversely affect our ability to obtain necessary insurance.

Although we maintain insurance policies with respect to certain of our related exposures, certain of these policies are subject to high deductibles; as such, we are, in effect, self-insured for substantially all of our typical claims. Our estimates of liabilities for unpaid claims and associated expenses and the appropriateness of the estimated liability are reviewed and updated quarterly. However, insurance liabilities are difficult to assess and estimate due to the many relevant factors, the effects of which are often unknown, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents that have occurred but are not reported, and the effectiveness of our health, safety and quality programs. Our accruals are based on known facts, historical trends (both internal trends and industry averages) and our reasonable estimate of our future expenses. We believe our accruals are adequate. However, our risk management strategies and techniques may not be fully effective in mitigating the risk exposure in all market environments or against all types of risk. If any of the variety of instruments, processes or strategies we use to manage our exposure to various types of risk are not effective, we may incur losses that are not covered by our insurance policies (including potential punitive damages awards) or that exceed our accruals or coverage limits.

Additionally, in recent years, insurance markets have become more expensive and restrictive. Also, our prior casualty loss history might adversely affect our ability to procure insurance within commercially reasonable ranges. As such, we may not be able to maintain commercially reasonable levels of insurance coverage in the future, which could preclude our ability to work on many projects. Our insurance providers are under no commitment to renew our existing insurance policies in the future; therefore, our ability to obtain necessary levels or kinds of insurance coverage are subject to market forces outside our control. If we are unable to obtain necessary levels of insurance, we likely would be unable to compete for or work on most projects.

Our use of the cost-to-cost method of accounting could result in a reduction or reversal of previously recorded revenue or profits.

A material portion of our revenue is recognized using the cost-to-cost method of accounting, which results in recognizing contract revenue and earnings ratably over the contract term in the proportion that our actual costs bear to our estimated contract costs. The earnings or losses recognized on individual contracts are based on estimates of contract revenue, costs and profitability. We review our estimates of contract revenue, costs and profitability on an ongoing basis. Prior to contract completion, we may adjust our estimates on one or more occasions as a result of change orders to the original contract, collection disputes with the customer on amounts invoiced, or claims against the customer for increased costs incurred due to customer-induced delays and other factors. Contract losses are recognized in the fiscal period in which the loss is determined. Contract profit estimates are also adjusted in the fiscal period in which it is determined that an adjustment is required. As a result of the requirements of the cost-to-cost method of accounting, the possibility exists, for example, that we could have estimated and reported a profit on a contract over several periods and later determined, usually near contract completion, that all or a portion of such previously estimated and reported profits were overstated. If this occurs, the full aggregate amount of the overstatement will be reported for the period in which such determination is made, thereby offsetting all or a portion of any profits from other contracts that would be reported in such period, or even resulting in a loss being reported for such period. On a historical basis, in most business units, we believe that we have typically made reasonably reliable estimates of the progress towards completion on our long-term contracts. However, given the uncertainties associated with these types of contracts, it is possible for actual costs to materially and adversely vary from estimates previously made, which may result in reductions or reversals of previously recorded revenue and profits.

Earnings for future periods may be impacted by impairment charges for goodwill and intangible assets.

We carry a significant amount of goodwill and identifiable intangible assets on our consolidated balance sheets. Goodwill is the excess of purchase price over the estimated fair value of the net assets of acquired businesses. We assess goodwill for impairment each year, and more frequently if circumstances suggest an impairment may have occurred. We may determine in the future that a significant impairment has occurred in the value of our unamortized intangible assets or fixed assets, which could require us to write off a portion of our assets and could adversely affect our financial condition or reported results of operations.

Contractual warranty obligations could adversely affect our profits and cash flow.

We often warrant the services provided, typically as a function of contract, guaranteeing the work performed against defects in workmanship and the material we supply. If warranty claims occur, we could be required to repair or replace warrantied work in place at our cost. In addition, our customers may elect to repair or replace the warrantied item by using the services of another provider and require us to pay for the cost of the repair or replacement. Costs incurred as a result of warranty claims could adversely affect our financial position, results of operations and cash flows.

Recent and potential changes in U.S. trade policies, including changes to existing trade agreements and any resulting changes in international trade relations, and retaliatory responses from other countries may significantly increase the costs or limit supplies of raw materials and products used in our operations.

The U.S. federal government has in recent years imposed new or increased tariffs or duties on an array of imported materials and goods that are used in connection with our operations and the current presidential administration has already proposed or suggested that it will propose additional tariffs going-forward. Foreign governments and trading blocs have responded by imposing or increasing tariffs, duties and/or trade restrictions on U.S. goods, and may, from time to time, consider other measures, including additional retaliatory responses in the form of additional tariffs. The current presidential administration may continue to alter the U.S.’s approach to international trade, which may impact existing bilateral or multi-lateral trade agreements and treaties with foreign countries. The current presidential administration has indicated that they are likely to impose further significant tariffs on imported materials and goods that may be used in connection with our operations. The imposition of such tariffs may strain international trade relations and increase the risk that foreign governments implement retaliatory tariffs on goods imported from the United States.

These political and economic changes could have a material effect on global economic conditions and the stability of financial markets and could significantly reduce global trade. It is unclear what future actions the U.S. government or foreign governments will or will not take with respect to tariffs or other international trade agreements and policies. Current trade negotiations may fail, which may exacerbate these risks.

In addition to potential increases on tariffs, wars or conflicts could affect our ability to obtain raw materials and products. Ongoing and future conflicts and other geopolitical events may result in sanctions or other export controls imposed by the U.S. or United Nations.

These trade conflicts and related escalating governmental actions that result in additional tariffs, duties and/or trade restrictions could increase our operating costs, cause disruptions or shortages in our supply chains and/or negatively impact the U.S., regional or local economies in which we operate, and, individually or in the aggregate, materially and adversely affect our business and our consolidated financial statements.

Rising inflation and/or interest rates, or deterioration of the United States economy could have a material adverse effect on our business, financial condition and results of operations.

Economic factors, including inflation and fluctuations in interest rates, recession and fears of recession could have a negative impact on our business. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. To the extent that Congress is unable to lower United States debt substantially or effectively increase the debt limit, a decrease in federal spending could result, which could negatively impact the ability of government agencies to fund existing or new infrastructure projects. Further, to the extent that Congress invests additional amounts in infrastructure during periods of labor shortages or supply chain disruptions, it may increase our costs or cause us not to find suitable labor, supplies, machinery or raw materials. In addition, all of such actions could have a material adverse effect on the financial markets and economic conditions in the United States and throughout the world, which may limit our ability and the ability of our customers to obtain financing and/or could impair our ability to execute our acquisition strategy. These and related economic factors could have a material adverse effect on our financial position, results of operations, cash flows and liquidity.

Continuing worldwide political and economic uncertainties may adversely affect our revenue and profitability.

The last several years have been periodically marked by political and economic concerns, including the COVID-19 pandemic, decreased consumer confidence, the effects of international conflicts such as wars between Russia and Ukraine and Israel and Hamas, tariffs, energy costs and inflation. This instability can make it extremely difficult for our customers, our vendors and us to accurately forecast and plan future business activities, and could cause constrained spending on our services, delays and a lengthening of our business development efforts, the demand for more favorable pricing or other terms, and/or difficulty in collection of our accounts receivable. Further, this ongoing economic instability in the global markets could limit our ability to access the capital markets at a time when we would like, or need, to raise capital, which could have an impact on our ability to react to changing business conditions or new opportunities. If economic conditions remain uncertain or weaken, our revenue and profitability could be adversely affected.

The global business environment remains marked by significant political and economic uncertainties, including the ongoing effects of pandemics, international conflicts such as the wars in Ukraine and between Israel and Hamas, persistent inflation, volatile energy prices, fluctuating consumer confidence, and geopolitical tensions. These factors create challenges for our customers, vendors, and us in accurately forecasting and planning business activities.

Economic instability may result in reduced or delayed customer spending on our services, extended business development cycles, increased demands for favorable pricing or contractual terms, and challenges in collecting accounts receivable. Additionally, volatility in global markets may restrict our ability to access capital when needed, potentially limiting our capacity to respond to changing business conditions or seize new opportunities.

If these or other uncertainties persist or worsen, they may materially and adversely impact our operations, revenue, and profitability.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under our Second A&R Wintrust Credit Agreement (as defined below) are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though any amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. In addition, previously, we have entered into an interest rate swap on our Second A&R Wintrust Revolving Loan that involves the exchange of variable for fixed rate interest payments in order to reduce interest rate volatility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we enter into may not fully mitigate our interest rate risk and could be subject to credit risk themselves. As of December 31, 2024, we had $35.8 million of available borrowing capacity under the Second A&R Wintrust Revolving Loan (as defined below).

Failure to remain in compliance with covenants under our debt and credit agreements or service our indebtedness could adversely impact our business.

Our Second A&R Wintrust Credit Agreement and other debt obligations include certain debt covenants, some of which are financial in nature, are further described in “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report on Form 10-K. Our failure to comply with any of these covenants, or to pay principal, interest or other amounts when due thereunder, would constitute an event of default under the applicable agreements. Under certain circumstances, the occurrence of an event of default under one of these agreements (or the acceleration of the maturity of the indebtedness under one of these agreements) may constitute an event of default under one or more of our other debt or surety agreements. Default under our debt agreements could result in, among other things, us no longer being entitled to borrow under one or more of the agreements, acceleration of the maturity of outstanding indebtedness under the agreements, and/or foreclosure on any collateral securing the obligations under the agreements. If we are unable to service our debt obligations, or if we are unable to comply with our financial or other debt covenants, and our indebtedness would become immediately due and payable, and we could be forced to curtail our operations, reorganize our capital structure (including through bankruptcy proceedings), or liquidate some or all of our assets in a manner that could cause holders of our securities to experience a partial or total loss of their investment.

We may not be able to generate sufficient cash flow to meet all of our existing or potential future debt service obligations.

Our ability to meet all of our existing or potential future debt service obligations (including those under our Second A&R Wintrust Credit Agreement, pursuant to which we may incur significant indebtedness), to refinance our existing or potential future indebtedness, and to fund our operations, working capital, acquisitions, capital expenditures, and other important business uses, depends on our ability to generate sufficient cash flow in the future. Our future cash flow is subject to, among other factors, general economic, industry, financial, competitive, operating, legislative and regulatory conditions, many of which are beyond our control.

We cannot assure that our business will generate sufficient cash flow from operations or that future sources of cash will be available to us on favorable terms, or at all, in amounts sufficient to enable us to meet all of our existing or potential future debt service obligations, or to fund our other important business uses or liquidity needs. Furthermore, if we incur additional indebtedness in connection with future acquisitions or for any other purpose, our existing or potential future debt service obligations could increase significantly and our ability to meet those obligations could depend, in large part, on the returns from such acquisitions or projects, as to which no assurance can be given.

Furthermore, our obligations under the terms of our borrowings could impact us negatively. For example, such obligations could:

• limit our ability to obtain additional financing for working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes;
• restrict us from making strategic acquisitions or cause us to make non-strategic divestitures;
• increase our vulnerability to general economic and industry conditions; and
• require a substantial portion of our cash flow from operations to be dedicated to the payment of principal and interest on our borrowings, thereby reducing our ability to use cash flow to fund our operations, capital expenditures and future business opportunities.

We may also refinance all or a portion of our indebtedness at or prior to the scheduled maturity. Our ability to refinance our indebtedness or obtain additional financing will depend on, among other things, (i) our business, financial condition, liquidity, results of operations, and then-current market conditions; and (ii) restrictions in the agreements governing our indebtedness. As a result, we may not be able to refinance any of our indebtedness or obtain additional financing on favorable terms, or at all.

If we do not generate sufficient cash flow from operations and additional borrowings or refinancings are not available to us, we may be unable to meet all of our existing or potential future debt service obligations. As a result, we would be forced to take other actions to meet those obligations, such as raising equity or delaying capital expenditures, any of which could have a material adverse effect on us. Furthermore, we cannot assure that we will be able to effect any of these actions on favorable terms, or at all.

Our obligation to contribute to multiemployer pension plans could give rise to significant expenses and liabilities in the future.

We contribute to approximately 50 multiemployer pension plans in the United States under collective bargaining agreements that generally provide pension benefits to employees covered by these agreements. Approximately 45% of our current employees are members of collective bargaining units. Our contributions to these plans were approximately $10.3 million for the year ended December 31, 2024 and $11.6 million and $12.6 million for the years ended December 31, 2023 and 2022, respectively. The costs of providing benefits through such plans have increased in recent years. The amount of any increase or decrease in our required contributions to these multiemployer pension plans will depend upon many factors, including the outcome of collective bargaining, actions taken by trustees who manage the plans, government regulations, the actual return on assets held in the plans and the potential payment of a withdrawal liability. Based upon the information available to us from the multiemployer pension plans’ administrators, we believe that some of these multiemployer pension plans are underfunded. The unfunded liabilities of these plans may result in required increased future payments by us and the other participating employers. Underfunded multiemployer pension plans may impose a surcharge requiring additional pension contributions. Our risk of such increased payments may be greater if any of the participating employers in these underfunded plans withdraws from the plan and is not able to contribute an amount sufficient to fund the unfunded liabilities associated with its participants in the plan.

With limited exception, an employer who is obligated under a collective bargaining agreement to contribute to a multiemployer pension plan is liable, upon termination of such contribution obligation to the plan or withdrawal from a plan, for its proportionate share of the plan’s unfunded vested pension liabilities. In the event that we withdraw from participation in a plan, applicable law could require us to make withdrawal liability contributions to such plan, and we would have to reflect that liability and the related expense in our consolidated financial statements. Our withdrawal liability payable to an individual multiemployer pension plan would depend on the extent of the plan’s funding of vested benefits. While we currently have no intention of withdrawing from a plan, and underfunded plan obligations have not affected our operations in the past, there can be no assurance that we will not be required to make material cash contributions to one or more of these plans in the future. If the multiemployer pension plans in which we participate have significant underfunded liabilities, such underfunding could increase the size of our potential withdrawal liability. No liability for underfunding of multiemployer pension plans was recorded in our consolidated financial statements for the years ended December 31, 2024 or 2023.

Increases in healthcare costs could adversely affect our financial results.

The costs of providing employee healthcare benefits have steadily increased over a number of years due to, among other things, rising healthcare costs and legislative requirements. Because of the complex nature of healthcare laws, as well as periodic healthcare reform legislations adopted by Congress, state legislatures, and municipalities, we cannot predict with certainty the future effect of these laws on our healthcare costs. Continued increases in healthcare costs or additional costs created by future health care reform laws adopted by Congress, state legislatures, or municipalities could adversely affect our results of operations and financial position.

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, difficult site conditions, and 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, 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.

A pandemic, epidemic or outbreak of an infectious disease, such as the coronavirus (“COVID-19”), in the markets in which we operate or that otherwise impacts our facilities or suppliers could adversely impact our business.

If a pandemic, epidemic, or outbreak of an infectious disease, or other public health crisis were to affect our markets or facilities or those of our suppliers, or customers, our business could be adversely affected. Consequences of a pandemic, epidemic or other infectious disease may include disruptions in or restrictions on our ability to travel. If such an infectious disease broke out at one or more of our offices, facilities or work sites, our operations may be adversely and materially affected, our productivity may be affected, our ability to complete projects in accordance with our contractual obligations may be affected, and we may incur increased labor and materials costs. If the customers with which we contract are affected by an outbreak of infectious disease, ODR and GCR work may be delayed or cancelled, and we may incur increased labor and materials costs. If our subcontractors with whom we work were affected by an outbreak of infectious disease, our labor supply may be affected and we may incur increased labor costs. In addition, we may experience difficulties with certain suppliers or with vendors in their supply chains, and our business could be affected if we become unable to procure essential equipment, supplies or services in adequate quantities and at acceptable prices. Further, pandemics, epidemics, infectious outbreaks or other public health crisis’ have and could in the future cause disruption to the U.S. economy, or the local economies of the markets in which we operate, and may cause shortages of building materials, increased costs associated with obtaining building materials, affect job growth and consumer confidence, or cause economic changes, including the possibility of an economic recession or inflation, that we cannot anticipate. Overall, the potential impact of a pandemic, epidemic, outbreak of an infectious disease or other public health crisis with respect to our markets or our facilities is difficult to predict and could adversely impact our business.

Future climate change could adversely affect us.

Greenhouse gas (“GHG”) emissions are driving global climate change that is expected to have various impacts on our operations, ranging from more frequent extreme weather events to extensive governmental policy developments and shifts in our customers’ preferences, which have the potential individually or collectively to significantly disrupt our business as well as negatively affect our suppliers, independent contractors and customers. Experiencing or addressing the various physical, regulatory and adaptation/transition risks from climate change may significantly reduce our revenue and profitability, or cause us to generate losses. For instance, incorporating greater resource efficiency into our solutions, whether to comply with upgraded building codes or recommended practices given a region’s particular exposure to climate conditions, or undertaken to satisfy demand from increasingly environmentally conscious customers or to meet our own sustainability goals, often raises our costs. In evaluating whether to implement voluntary improvements, we also consider that choosing not to enhance our buildings’ resource efficiency can make them less attractive to municipalities, and increase the vulnerability of customers in our communities to rising energy and water expenses and use restrictions. We weigh the impact of the costs associated with offering more resource-efficient products against our priorities of generating higher returns and delivering solutions that are affordable to our customers. In balancing these objectives, we may determine we need to absorb most or all of the additional operating costs that come with making our solutions more efficient, which may be substantial for us.

Beyond the commercial pressures implicated by climate change concerns, our operations in any of our served markets may face its potential adverse physical effects. While we have safety protocols in place for our construction sites and take steps to safeguard our administrative functions, we can provide no assurance that we or our suppliers or other partners can successfully operate in areas experiencing a significant weather event or natural disaster, and we or they may be more impacted and take longer, and with higher costs, to resume operations in an affected location than other businesses, depending on the nature of the event or other circumstances.

International, federal, state and local authorities and legislative bodies have issued, implemented or proposed regulations, penalties, standards or guidance intended to restrict, moderate or promote activities consistent with resource conservation, GHG emission reduction, environmental protection or other climate-related objectives. Compliance with those directed at or otherwise affecting our business or our suppliers’ (or their suppliers’) operations, products or services, could increase our costs or delay or complicate our solutions, for example, due to a need to reformulate or redesign building materials or components, or source updated or upgraded items or equipment, or specially trained or certified independent contractors, in limited or restricted supply.

Adapting to or transitioning from the use of certain items or methods in construction or other solutions, or adjusting the products we offer to our customers, whether due to climate-related governmental rules or our supply chain, market dynamics or consumer preferences, can negatively affect our costs and profitability, production operations in affected markets and customer satisfaction during the transition period, which could be prolonged.

Climate change is an intrinsically complex global phenomenon with inherent residual risks across its physical, regulatory and adaptation/transition dimensions that cannot be mitigated given their wide-ranging, (sometimes unexpectedly) interdependent and largely unpredictable potential scope, nature, timing or duration. Therefore, we cannot provide any assurance that we have or can successfully prepare for, or are or will be able to reduce or manage, any of them to the extent they may arise. In addition, we may experience substantial negative impacts to our business if an unexpectedly severe weather event or natural disaster damages our operations or those of our suppliers or independent contractors in our primary markets or from the unintended consequences of regulatory changes that directly or indirectly impose substantial restrictions on our activities or adaptation requirements.

We may be affected by market or regulatory responses to climate change, including potential policy shifts under the current presidential administration.

Public and regulatory focus on climate change continues to evolve, influencing the actions of local, state, national, and international bodies. While previous presidential administrations prioritized climate change initiatives such as rejoining the Paris Agreement, setting GHG emission reduction targets, and finalizing the SEC 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 (the “SEC Climate Rules”), whose implementation, after significant legal challenges, was voluntarily paused by the SEC in April 2024 pending judicial review, the current presidential administration may reverse or significantly alter these regulatory trends. Historically, the current presidential administration pursued policies aimed at reducing regulatory burdens on businesses, including the rollback of environmental regulations, withdrawal from the Paris Agreement, and easing restrictions on fossil fuel production.

If the current presidential administration adopts similar policies, it may lead to reduced enforcement or elimination of federal climate-related regulations, potentially lowering compliance costs for us and our customers, particularly those in fossil fuel or emissions-intensive industries. However, any such deregulatory actions could create uncertainty for businesses already working to meet stricter climate-related rules and commitments, including those required by state, municipal, or international regulations, such as California's mandatory GHG disclosure laws adopted in September 2023.

Additionally, ongoing market and investor pressure for greater sustainability and climate-related disclosures may persist regardless of federal regulatory changes.

If federal deregulatory actions conflict with state or local climate initiatives, such as California's GHG disclosure requirements, it could create a fragmented regulatory environment, increasing operational complexity and compliance costs for us and our customers. Further, uncertainty surrounding federal climate policy may delay or alter customer decision-making on energy transition projects, reducing demand for our services in certain areas.

We cannot predict with certainty the extent to which federal, state, or international climate-related regulations, or their potential rollbacks, will impact our business, financial condition, or operations. However, changes in climate policy or market dynamics under the current presidential administration could materially affect our operations, costs, and profitability.

Increasing scrutiny and changing expectations from investors and customers with respect to our environmental, social and governance (“ESG”) practices may impose additional costs on us or expose us to reputational or other risks.

Investors and customers are placing growing emphasis on the ESG practices of companies across industries, including the environmental impact of operations, human capital management and corporate governance. Many investors rely on third-party benchmarks, ratings, or scores to measure a company’s ESG practices, which can influence investment decisions or lead to engaging with companies to require changes to their practices. Similarly, some customers may evaluate our ESG performance or require us to adopt specific ESG policies as a condition of awarding contracts.

While ESG expectations are evolving, they remain varied and subject to differing standards among investors, customers, and regulators. Under the previous presidential administration, there was a significant push to advance ESG-related regulations, including the SEC Climate Rules, which would have required extensive reporting on climate risks and GHG emissions. However, these rules have been delayed by legal challenges, and the current presidential administration has signaled an intent to reduce regulatory burdens on businesses, which could include altering or eliminating ESG-related requirements. These potential changes could create further uncertainty around the ESG expectations of investors and customers.

Furthermore, organizations that provide ESG ratings or scores may assign us unfavorable ratings, whether due to our own practices, industry trends or insufficient disclosures. Such ratings could negatively influence investor sentiment, divert investment capital to other companies or industries and adversely impact our stock price and cost of capital.

Additionally, even in a deregulatory environment, market and stakeholder pressures around ESG are likely to persist. Responding to these expectations may require increased costs for compliance, reporting, and operational adjustments, or expose us to the risk of stockholder activism, all of which could materially affect our business, operations, and financial condition.

We are susceptible to adverse weather conditions and the increasing frequency and severity of extreme weather events, which may harm our business and financial results.

Our business may be adversely affected by severe weather conditions, including hurricanes, tornadoes, floods, wildfires, extreme heat, and other extreme weather events, particularly in areas where we have significant operations. The increasing frequency and intensity of such events, driven by climate change, exacerbate the risks to our operations. Repercussions of severe weather conditions may include:

• curtailment or suspension of services and operations;
• inability to meet performance schedules in accordance with contracts, potentially leading to liability for liquidated damages or reputational harm;
• injuries or fatalities;
• weather related damage to facilities, equipment, and infrastructure;
• disruption of information systems or communication networks;
• increased insurance premiums, deductibles, or potential lack of adequate insurance coverage for weather-related losses;
• inability to receive machinery, equipment and materials at jobsites; and
• loss of productivity.

Information technology system failures, network disruptions or cybersecurity breaches could adversely affect our business.

We use sophisticated information technology systems, networks, and infrastructure in conducting some of our day-to-day operations and providing services to certain customers, including technology used for building designs, project modeling and scheduling. Information technology system failures, including suppliers’ or vendors’ system failures, could disrupt our operations by causing transaction errors, processing inefficiencies, the loss of customers, other business disruptions, or the loss of employee personal information. In addition, these systems, networks, and infrastructure may in the future be vulnerable to deliberate cyber-attacks that interfere with their functionality or the confidentiality of our data or information or our customers’ data or information. Increasingly advanced cyber-attacks against rapidly evolving computer technologies pose a risk to the security of our systems, networks, information and data. In addition, the rapid evolution and increased adoption of artificial intelligence technologies may intensify our cybersecurity risks by introducing new vulnerabilities. Likewise, cyber incidents, including malicious cyber-attacks perpetrated on our employees and cyber incidents caused by third parties surreptitiously accessing our systems by other means, are an on-going risk to the security of the systems, networks, information and data of ours, our customers, subcontractors and suppliers. While we have security, internal control and technology measures in place to protect our systems and networks, confidential business information, personal data of ours, our customers, employees, suppliers and subcontractors, our information technology systems and those of our third-party service providers have been and may in the future be subject to system breaches. System breaches can lead to disclosure, modification and destruction of proprietary business data, personally identifiable information, other sensitive information, production downtime or loss of business, and damage to our reputation, competitiveness and operations. Increased interconnectivity with third-party systems and reliance on cloud-based services further expose us to security risks from vulnerabilities in third-party platforms. In addition, flexible working arrangements at our corporate offices increased as a result of the COVID-19 pandemic, and these arrangements have resulted in a higher extent of remote working. This and other possible changing work practices may adversely impact our ability to maintain the security, proper function and availability of our information technology and systems since remote working by our employees could strain our technology resources and introduce operational risk, including heightened cybersecurity risk. Remote and hybrid working environments may be less secure and more susceptible to hacking attacks, including phishing and social engineering attempts that have sought, and may seek, to exploit remote working environments. Of special note is our risk when implementing new capabilities. The implementation of new systems and information technology could adversely impact our operations by requiring substantial capital expenditures, diverting management’s attention, or causing delays or difficulties in transitioning to new systems. As we implement new systems, many times both new and old systems run in parallel until all processes have successfully transferred to the new system and thorough testing has been performed. These events could impact our customers, suppliers, subcontractors, employees, our financial reporting and our reputation and lead to financial losses from remediation actions, loss of business or potential liability, or an increase in expense, all of which may have a material adverse effect on our business. Our systems implementations may also not result in productivity improvements at the levels anticipated. In addition, current and future laws and regulations governing data privacy and the unauthorized disclosure of confidential information, including, but not limited to SEC rules finalized in 2023 requiring enhanced cybersecurity risk disclosures, may pose complex compliance challenges and result in additional costs. A failure to comply with such laws and regulations could result in penalties or fines, legal liabilities or reputational harm. Continuing and evolving threat of cyber-attacks and increased regulatory focus on cybersecurity risk management and incident reporting, along with potential new federal, state, or international requirements, may require significant additional resources and investment, potentially adversely affecting our results of operations and cash flows.

Artificial intelligence is an emerging area of technology that has the potential to impact various aspects of our business operations.

The development, adoption, and use for generative artificial intelligence (“AI”) technologies are still in their early stages and ineffective or inadequate AI development or deployment practices by the Company or third-party vendors could result in unintended consequences. We contract third-party vendors that use AI in products and/or services they provide and we may not have full control or visibility over the quality, performance, security or compliance of the products and services that incorporate AI-related technology. AI algorithms that our third-party vendors use may be flawed or may be based on datasets that are biased or insufficient. These limitations or failures could result in reputational damage and legal liabilities. Developing, testing, and deploying resource-intensive AI systems may require additional investment and increase our costs. In addition, the evolving nature of AI may cause new laws and regulations to be enacted which may require significant resources to modify and maintain business practices to comply with the new laws and regulations, the nature of which cannot be determined at this time. Further, inaccurate results generated as a result of our employees’, contractors’ or vendors’ use of generative AI technologies could lead to operational interruptions or reputational harm.

Changes to our outsourced software or infrastructure vendors as well as any sudden loss, breach of security, disruption or unexpected data or vendor loss associated with our information technology systems could have a material adverse effect on our business.

We rely on third-party software and infrastructure to run critical accounting, project management and financial information systems. If software or infrastructure vendors decide to discontinue further development, integration or long-term maintenance support for our information systems, or there is any system interruption, delay, breach of security, loss of data or loss of a vendor, we may need to migrate some or all of our accounting, project management and financial information to other systems.

These disruptions could increase our operational expenses as well as impact the management of our business operations, which could have a material adverse effect on our financial position, results of operations, cash flows and liquidity.

We have subsidiary operations throughout the United States and are exposed to multiple state and local regulations, as well as federal laws and requirements applicable to government contractors. Changes in laws, regulations or requirements, or a material failure of any of our subsidiaries or us to comply with any of them, could increase our costs and have other negative impacts on our business.

As of December 31, 2024, our business units operate in 22 states, which exposes us to a variety of state and local laws and regulations, particularly those pertaining to contractor licensing requirements. These laws and regulations govern many aspects of our business, and there are often different standards and requirements in different locations. In addition, our subsidiaries that perform work for federal government entities are subject to additional federal laws and regulatory and contractual requirements. Changes in any of these laws, or any subsidiary’s material failure to comply with them, can adversely impact our operations by, among other things, increasing costs, distracting management’s time and attention from other items, and harming our reputation.

As Federal Government Contractors under applicable federal regulations, our subsidiaries are subject to a number of rules and regulations, and our contracts with government entities are subject to audit. Violations of the applicable rules and regulations could result in a subsidiary being barred from future government contracts.

Federal Government Contractors must comply with many regulations and other requirements that relate to the award, administration and performance of government contracts. A violation of these laws and regulations could result in imposition of fines and penalties, the termination of a government contract, or debarment from bidding on government contracts in the future. Further, despite our decentralized nature, a violation at one of our locations could impact the ability of the other locations to bid on and perform government contracts; additionally, because of our decentralized nature, we face risk in maintaining compliance with all local, state and federal government contracting requirements. Prohibition against bidding on future government contracts could have an adverse effect on our financial position, results of operations and cash flows.

Past and future environmental, safety and health regulations could impose significant additional costs on us that reduce our profits.

The systems we install are subject to various statutes and regulations. There can be no assurance that the regulatory environment in which we operate will not change significantly in the future. Various local, state and federal laws and regulations impose licensing standards on technicians who install and service mechanical systems. And additional laws, regulations and standards apply to contractors who perform work that is being funded by public money, particularly federal public funding. Our failure to comply with these laws and regulations could subject us to substantial fines, the loss of licenses or potential debarment from future publicly funded work. It is impossible to predict the full nature and effect of judicial, legislative or regulatory developments relating to health and safety regulations and environmental protection regulations applicable to our operations.

Our failure to comply with immigration laws and labor regulations could affect our business.

In certain markets, we rely heavily on our immigrant labor force. We have taken steps that we believe are sufficient and appropriate to ensure compliance with immigration laws. However, we cannot provide assurance that our management has identified, or will identify in the future, all undocumented immigrants who work for us. Additionally, immigration laws and labor regulations are complex, subject to change, and vary across jurisdictions, which could create challenges for maintaining compliance.

The failure to identify such illegal immigrants may result in fines or other penalties being imposed upon us, which could have a material adverse effect on our financial position, results of operations and cash flows. Furthermore, increased enforcement of immigration laws, changes to employment verification requirements, or new legislation or regulations could further heighten these risks and lead to additional compliance costs, operational disruptions, or reputational harm.

Tax matters, including changes in corporate tax laws and disagreements with taxing authorities, could impact our results of operations and financial condition.

We conduct business across the United States and file income taxes in the federal and various state jurisdictions. Significant judgment is required in our accounting for income taxes. In the ordinary course of our business, there are transactions and calculations in which the ultimate tax determination is uncertain. Changes in tax laws and regulations, in addition to changes and conflicts in related interpretations and other tax guidance, could materially impact our provision for income taxes, deferred tax assets and liabilities, and liabilities for uncertain tax positions.

Issues relating to tax audits or examinations and any related interest or penalties and uncertainty in obtaining deductions or credits claimed in various jurisdictions could also impact the accounting for income taxes. Our results of operations are reported based on our determination of the amount of taxes we owe in various tax jurisdictions, and our provision for income taxes and tax liabilities are subject to review or examination by taxing authorities in applicable tax jurisdictions. An adverse outcome of such a review or examination could adversely affect our operating results and financial condition. Further, the results of tax examinations and audits could have a negative impact on our financial results and cash flows where the results differ from the liabilities recorded in our financial statements.

Risks Related to Ownership of Our Common Stock

The price of our common stock may be volatile.

The market price of our common stock has been volatile and may be volatile in the future, and could be subject to wide fluctuations in price in response to various factors, some of which are beyond our control. These factors include, among other things:

• actual or anticipated variations in our quarterly results of operations;
• recommendations by securities analysts;
• operating and stock price performance of other companies that investors deem comparable to us;
• political and economic conditions;
• news reports relating to trends, concerns and other issues in the financial services industry generally;
• perceptions in the marketplace regarding us and/or our competitors;
• the addition or departure of key personnel;
• new technology used, or services offered, by competitors; and
• changes in government regulations.

In addition, if the market for stocks in our industry, or the stock market in general, experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, financial condition or results of operations. If any of the foregoing occurs, it could cause our stock price to fall and may expose us to lawsuits that, even if unsuccessful, could be costly to defend and a distraction to management.

Future sales of our common stock may cause our common stock price to decline.

Any transfer or sales of substantial amounts of our common stock in the public market or the perception that such transfer or sales might occur may cause the market price of our common stock to decline. As of March 6, 2025, we had an aggregate of 11,353,379 shares of our outstanding common stock, of which 1,074,684 shares were held by our current directors and officers. There were no holders of greater than 10% of our common stock as of March 6, 2025. If a substantial number of these shares are sold in the public market, the trading price of our common stock may decline.

In addition, our Board of Directors has the power, without stockholder approval, to set the terms of any series of preferred stock that may be issued, including voting rights, dividend rights, and preferences over our common stock with respect to dividends or in the event of a dissolution, liquidation or winding up and other terms. In the event that we issue preferred stock in the future that has preference over our common stock with respect to payment of dividends or upon our liquidation, dissolution or winding up, or if we issue preferred stock with voting rights that dilute the voting power of our common stock, the rights of the holders of our common stock or the market price of our common stock could be adversely affected.

Future equity issuances could result in dilution, which could cause our common stock price to decline.

We are generally not restricted from issuing additional shares of our common stock, up to the 100,000,000 shares of voting common stock authorized by our second amended and restated certificate of incorporation, which could be increased by a vote of the holders of a majority of our shares of common stock. In addition, we may issue additional shares of our common stock in the future pursuant to current or future equity compensation plans, upon conversions of preferred stock or debt, upon exercise of warrants or in connection with future acquisitions or financings. If we choose to raise capital by selling shares of our common stock for any reason, the issuance would have a dilutive effect on the holders of our common stock and could have a material negative effect on the market price of our common stock.

If equity research analysts publish unfavorable commentary or downgrade our common stock, the price and trading volume of our common stock could decline.

The trading market for our common stock could be affected by equity research analysts’ research or reports about us and our business. The price of our stock could decline if one or more securities analysts downgrade our stock or if analysts issue other unfavorable commentary about us or our business. In addition, if any of these analysts ceases coverage of us, we could lose visibility in the market, which in turn could cause our common stock price or trading volume to decline and our common stock to be less liquid.

We have not declared any dividends on our common stock to date and have no expectation of doing so in the foreseeable future.

The payment of cash dividends on our common stock rests within the discretion of our Board of Directors and will depend, among other things, upon our earnings, unencumbered cash, capital requirement and our financial condition, as well as other relevant factors. To date, we have not paid dividends on our common stock nor do we anticipate that we will pay dividends in the foreseeable future. As of December 31, 2024, we do not have any preferred stock outstanding that has any preferential dividends.

Provisions in our organizational documents and Delaware or certain other state laws could delay or prevent a change in control of our company, which could adversely affect the price of our common stock.

The provisions of our certificate of incorporation and our bylaws could have the effect of delaying, deferring or discouraging another person from acquiring control of our company. These provisions, which are summarized below, may have the effect of discouraging takeover bids. They are also designed in part to encourage persons seeking to acquire control of us to negotiate first with our Board of Directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms.

Our certificate of incorporation and our bylaws include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our company, including the following:

• Board of Directors’ vacancies. Our Certificate of Incorporation authorizes our Board of Directors to fill vacant directorships, including newly created seats. In addition, the number of directors constituting our Board of Directors is permitted to be set only by a resolution adopted by a majority vote of our Board of Directors, provided the number of directors may not be fewer than one and not more than nine. These provisions prevent a stockholder from increasing the size of our Board of Directors and then gaining control of our Board of Directors by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our Board of Directors but promotes continuity of management.
• Classified board. Our Certificate of Incorporation provides that our Board of Directors is classified into three classes of directors, each with staggered three-year terms. A third party may be discouraged from making a tender offer or otherwise attempting to obtain control of us as it is more difficult and time consuming for stockholders to replace a majority of the directors on a classified board of directors.
• Stockholder action: special meetings of stockholders. Our Certificate of Incorporation provides that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. As a result, a holder controlling a majority of our capital stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called in accordance with our bylaws. Further, our bylaws provide that special meetings of our stockholders may be called only by the chairperson of our Board of Directors, our President and Chief Executive Officer or our Board of Directors pursuant to a resolution of a majority of our Board of Directors, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.
• Advance notice requirements for stockholder proposals and director nominations. Our bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our bylaws also specify certain requirements regarding the form and content of a stockholder's notice. In addition, any stockholder nomination must meet the requirements of Rule 14a-19(b) under the Exchange Act. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders if the proper procedures are not followed. We expect that these provisions might also

discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of our company.

• Directors removed only for cause. Our Certificate of Incorporation provides that stockholders may remove directors only for cause, which may delay the ability of our stockholders to remove directors from our Board of Directors.
• Issuance of undesignated preferred stock. Following the repurchase of all of our previously issued shares of Class A Preferred Stock, our Board of Directors has the authority, without further action by the stockholders, to issue up to 600,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated time to time by our Board of Directors. The existence of authorized but unissued shares of preferred stock enables our Board of Directors to render more difficult or to discourage an attempt to obtain control of us by merger, tender offer, proxy contest or other means.
• Amendment of charter provisions. Any amendment of the above provisions in our Certificate of Incorporation requires approval by holders of at least 66.67% of our outstanding common stock.
• No cumulative voting. The Delaware General Corporation Law provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation's certificate of incorporation provides otherwise. Our Certificate of Incorporation does not provide for cumulative voting.
• Choice of forum. Our Certificate of Incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our Certificate of Incorporation or our bylaws; any action asserting a claim against us that is governed by the internal affairs doctrine. This provision is not intended to apply to claims arising under the Securities Act and the Exchange Act. To the extent the provision could be construed to apply to such claims, there is uncertainty as to whether a court would enforce the provision in such respect, and our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

General Risk Factors

Failure or circumvention of our disclosure controls and procedures or internal controls over financial reporting could seriously harm our financial condition, results of operations, and business.

We plan to continue to maintain and strengthen internal controls and procedures to enhance the effectiveness of our disclosure controls and internal controls over financial reporting. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, and not absolute, assurances that the objectives of the system are met. Any failure of our disclosure controls and procedures or internal controls over financial reporting could harm our financial condition and results of operations.

Our management has concluded that our disclosure controls and procedures and internal control over financial reporting are effective. However, if we are unable to establish and maintain effective disclosure controls and internal control over financial reporting or have material weaknesses in our internal control over financial reporting, our ability to produce accurate financial statements on a timely basis could be impaired, and the market price of our securities may be negatively affected.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. However, if we were unable to maintain effective internal control over financial reporting, or if we identify additional material weaknesses in our internal control over financial reporting, our management would be unable to assert in future reports that our disclosure controls and procedures and our internal control over financial reporting are effective. This could cause investors, counterparties and customers to lose confidence in the accuracy and completeness of our financial statements and reports and have a material adverse effect on our liquidity, access to capital markets and perceptions of our creditworthiness and/or a decline in the market price of our common stock. In addition, we could become subject to investigations by Nasdaq, the SEC or other regulatory authorities, which could require additional financial and management resources. These events could have a material adverse effect on our business, financial condition and results of operations.

Actual and potential claims, lawsuits and proceedings could ultimately reduce our profitability and liquidity and weaken our financial condition.

We have been and will continue to be named as a defendant in legal proceedings claiming damages in connection with the operation of our business. These actions and proceedings may involve claims for, among other things, compensation for alleged personal injury, workers’ compensation, employment law violations and/or discrimination, breach of contract, or property damage. In addition, we may be subject to lawsuits involving allegations of violations of the Fair Labor Standards Act and state wage and hour laws. We may also face allegations of violations of applicable securities laws, including the possibility of class action lawsuits. Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of any such actions or proceedings. We also are, and will likely continue to be from time to time, a plaintiff in legal proceedings against customers, or will pursue claims against our customers prior to litigation in which we seek to recover payment of contractual amounts we are owed, as well as claims for increased costs we incur. When appropriate, we will establish provisions against possible exposures, and adjust these provisions from time to time according to ongoing exposure. If the assumptions and estimates related to these exposures prove to be inadequate or inaccurate, we could experience a reduction in our profitability and liquidity and a weakening of our financial condition. In addition, claims, lawsuits and proceedings may harm our reputation or divert management resources away from operating the business. See Note 13 — Commitments and Contingencies in the accompanying notes to the Company’s consolidated financial statements for further information regarding the Company’s legal proceedings.

Force majeure events, including natural disasters and terrorist actions, could negatively impact our business, which may affect our financial position, results of operations or cash flows.

Force majeure, or extraordinary events beyond the control of the contracting parties, such as natural and man-made disasters, terrorist actions, and state and federal government shutdowns, could negatively impact us. We attempt to negotiate contract language seeking to mitigate force majeure events in both public and private customer contracts. When successful, we remain obligated to perform our services after most extraordinary events subject to relief that may be available pursuant to a force majeure clause. If we are not able to react quickly to force majeure events, our operations may be affected significantly, which may have a negative impact on our financial position, results of operations and cash flows.

Deliberate, malicious acts, including terrorism and sabotage, could damage our facilities, disrupt our operations or injure our employees, contractors, customers or the public and result in liability to us.

Intentional acts of theft, vandalism and destruction could damage or destroy our facilities, as well as the materials and equipment our labor forces are installing, thereby reducing our operational production capacity and requiring us to repair or replace facilities or installed work at substantial cost. Additionally, our employees, contractors and the public could suffer substantial physical injury from acts of terrorism for which we could be liable. Governmental authorities may also impose security or other requirements that could make our operations more difficult or costly. The consequences of any such actions could adversely affect our financial position, results of operations and cash flows.

A change in tax laws or regulations of any federal or state jurisdiction in which we operate could increase our tax burden and otherwise adversely affect our financial position, results of operations, cash flows and liquidity.

We continue to assess the impact of various U.S. federal or state legislative proposals that could result in a material increase to our U.S. federal or state taxes. We cannot predict whether any specific legislation will be enacted or the terms of any such legislation. However, if such proposals were to be enacted, or if modifications were to be made to certain existing regulations, the consequences could have a material adverse impact on us, including increasing our tax burden, increasing the cost of tax compliance or otherwise adversely affecting our financial position, results of operations and cash flows.

Changes in accounting rules and regulations could adversely affect our financial results.

Accounting rules and regulations are subject to review and interpretation by the Financial Accounting Standards Board (the “FASB”), the SEC and various other governing bodies. A change in U.S. GAAP could have a significant effect on our reported financial results. Additionally, the adoption of new or revised accounting principles could require that we make significant changes to our systems, processes and controls. We cannot predict the effect of future changes to accounting principles, which could have a significant effect on our reported financial results and/or our results of operations, cash flows and liquidity.

Actions of activist investors could disrupt our business.

Public companies have been the target of activist investors. In the event that a third party, such as an activist investor, proposes to change our governance policies, board of directors, or other aspects of our operations or strategy, our review and consideration of such proposals may create a significant distraction for our management and employees. This could negatively impact our ability to execute various strategic initiatives and may require management to expend significant time and resources responding to such proposals. Such proposals may also create uncertainties with respect to our financial position and operations and may adversely affect our ability to attract and retain key employees.

The Company’s Board of Directors recognizes the critical importance of developing, implementing, and maintaining robust cybersecurity measures to assess, identify, and manage material risks associated with cybersecurity threats, as such term is defined in Item 106(a) of Regulation S-K. These risks include, among other things, internal information technology risks; system security risks; data protection; risks to proprietary business information; intellectual property theft; fraud; extortion; harm to team members, partners, or customers; violation of privacy or security laws and other litigation and legal risk; and reputational risks. The Company has implemented a cybersecurity risk management program that aligns with the National Institute of Standards and Technology (NIST) Cybersecurity Framework to manage such material risks and to safeguard the Company’s information systems, protect the confidentiality, integrity, and availability of the Company’s and its customers’ data, and maintain the trust and confidence of our customers, business partners and team members.

Risk Management and Strategy

The Board of Directors is actively involved in oversight of the Company’s risk management framework and the Company’s cybersecurity risk management practices are strategically integrated into its broader risk management framework to promote a company-wide culture of cybersecurity risk management. This integration attempts to ensure that cybersecurity considerations are an integral part of decision-making processes throughout the Company. The Company’s risk management team works closely with the Company’s IT department to continuously evaluate and address cybersecurity risks in alignment with the Company’s overall business objectives and operational needs. The Company has implemented controls and procedures that are designed to provide for the prompt escalation of any cybersecurity concerns so that management, the Audit Committee, and the Board of Directors receive appropriate information in a timely manner.

Due to the complexity and evolving nature of cybersecurity threats, the Company has engaged from time-to-time external experts, including cybersecurity assessors, third-party legal consultants, and auditors, to evaluate and test its risk management systems. The Company engages these third-parties to conduct regular audits, threat assessments and consultation on security enhancements. These interactions are intended to enable the Company to leverage specialized knowledge and insights, in an attempt to ensure its cybersecurity strategies and processes remain at the forefront of industry practices.

In furtherance of assessing, identifying, and managing material cybersecurity risks; the Company:

• Employs advanced technology solutions, such as proactive detection tools, to safeguard our assets and identify threats within its environment.
• Conducts routine cyber education and awareness training sessions to empower team members with the necessary knowledge and cultivate a strong security culture across the organization.
• Regularly assesses our cybersecurity program against the NIST Cybersecurity Framework, using the findings to develop action plans and track progress to completion.
• Organizes tabletop exercises and drills to simulate cyber incidents, enhancing its incident response and recovery capabilities.
• Analyzes internal and external cybersecurity incidents and threat intelligence to assess their relevance to its environment and industry, crafting actionable plans accordingly.
• Manages an enterprise-wide disaster recovery governance program, including cybersecurity-related standards and compliance procedures.
• Performs regular cybersecurity-related disaster recovery testing to ensure the recoverability of its critical systems, supporting business continuity across various lines.
• Fosters integration between business units and corporate divisions with its internal cybersecurity team, embedding cybersecurity requirements into operational environments and influencing strategic decisions, budgeting, and processes (e.g., Security by Design). Additionally, senior management, executives, and the Board of Directors consistently review financial planning processes concerning cybersecurity initiatives.

Additionally, the Company is aware of the risks associated with third-party service providers, it implements stringent processes to oversee and manage these risks. The Company conducts security assessments of third-party technology providers before engagement and maintains ongoing monitoring to ensure compliance with Company cybersecurity standards. The monitoring includes assessments (e.g., reviewing vendor cybersecurity related attestation and disclosures (SOC 2 Type 2, etc.)) by the Company’s Senior Vice President and Chief Information Officer (“CIO”) and on an ongoing basis by its security engineers.

Governance

The Company’s CIO is the member of the Company’s management team primarily responsible for assessing, monitoring and managing the Company cybersecurity program. The Company’s CIO has over 20 years of experience in the field of technology and security including experience as an enterprise CIO, as well as consulting experience advising organizations on their technology and risk profiles. The Company believes its CIO’s in-depth knowledge and experience are instrumental in developing and designing, implementing and executing the Company’s cybersecurity strategies.

The Company’s CIO oversees the day-to-day implementation of the Company’s cybersecurity risk management programs, tests its compliance with standards, remediates known risks, and leads its employee cybersecurity training program. The CIO is tasked with keeping informed about the latest developments in cybersecurity, including potential threats and innovative risk management techniques, in an attempt to assist in effectively preventing, detecting, mitigating, and remediating cybersecurity incidents. The CIO implements and oversees processes for the regular monitoring of the Company’s information systems, including the deployment of advanced security measures and regular system audits to identify potential vulnerabilities. In the event of a cybersecurity incident, the CIO is responsible for implementing the Company’s incident response plan to mitigate the cybersecurity incident’s immediate impact, implement long-term strategies for remediation, and prevent future incidents.

The CIO regularly informs the Company’s Executive Vice President and Chief Financial Officer (“CFO”) and President and Chief Executive Officer (“CEO”) of material aspects related to cybersecurity risks and incidents regarding the Company. This ensures that the highest levels of management are kept abreast of the cybersecurity posture and potential risks facing the Company.

The Company’s Board of Directors believes it understands the significance of risks associated with cybersecurity threats to its operational integrity and stakeholder confidence and believes it has established mechanisms to effectively manage such risks based on the current understanding of the threat environment. As part of the Company’s entire Board of Directors operational risk management responsibilities, it has oversight of risks from cybersecurity threats. Notwithstanding that fact, the full Board of Directors has been designated as primary responsible for oversight of the Company’s cybersecurity risk management. As discussed below, management reports to the entire Board of Directors about cybersecurity threat risks, among other cybersecurity related matters, at least annually and management also reports to the Audit Committee with respect to cybersecurity risks regarding financial statements or financial statements reporting implications. The Audit Committee routinely interacts and reports to the entire Board of Directors on these matters.

The Board of Directors is composed of members with diverse expertise, including risk management, technology, and finance domain expertise, equipping them to oversee cybersecurity risks effectively. Further, certain members of the Board of Directors are National Association of Corporate Directors (“NACD”) CERT Certified in cybersecurity oversight.

The Board of Directors and the Audit Committee receive briefings from the Company’s CFO and CEO on a regular basis, with a minimum frequency of once per year. These briefings encompass a broad range of topics, including:

• Current cybersecurity landscape and emerging threats;
• Status of ongoing cybersecurity initiatives and strategies;
• Incident reports and learnings from any cybersecurity events; and
• Compliance with regulatory requirements and industry standards.

In addition to their regularly scheduled meetings, members of the Board of Directors, the CIO, CFO and CEO regularly engage in ad hoc conversations regarding emerging or potential cybersecurity risk and developments in the cybersecurity domain. The Board of Directors actively participates in strategic decisions making related to cybersecurity, offering guidance and approval for major initiatives. This involvement ensures that cybersecurity considerations are integrated into the broader strategic objectives of the Company. The Board of Directors conducts an annual review of the Company’s cybersecurity posture and the effectiveness of its risk management strategies. This review is helpful for identifying areas for improvement and ensuring the alignment of cybersecurity efforts with the overall risk management framework.

As of the date hereof, the Company is not aware of any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to have been identified or are anticipated to have a material adverse effect on the Company’s business strategy, results of operations, and financial condition. Despite its efforts to maintain processes which mitigate cybersecurity risks, there is no guarantee that such risks may not have a material effect on the Company’s business strategy, results of operations, and financial condition in the future. For additional information on cybersecurity risks the Company may face, see Part I, Item 1A. Risk Factors – “Information technology system failures, network disruptions or cybersecurity breaches could adversely affect our business.”

As of December 31, 2024, the Company leases several properties, consisting of offices, warehouses, fabrication and supply shops within 10 states across the eastern United States. Generally, these leases range from five to ten years and are on terms the Company believes to be commercially reasonable. A majority of these premises are leased from individuals or entities with whom the Company has no other business relationship. In certain instances, the Company leases property from current or former team members. The Company’s leased premises range in size from approximately 1,000 square feet to 150,000 square feet. To maximize available capital, the Company generally intends to keep leasing its properties, however, the Company may also consider purchasing a property where it believes ownership would be more economical. The Company utilizes substantially all of its leased property and believes there will be no difficulty either in negotiating the renewal of such leases as they expire or finding alternative space, if necessary.

See Note 14 — Leases in the accompanying notes to the Company’s consolidated financial statements for additional information regarding the Company’s leases.

The discussion that follows includes a comparison of the Company’s results of operations and liquidity and capital resources for the fiscal years ended December 31, 2024 and 2023. The Company has elected to omit discussion of the earliest of the three years covered by the consolidated financial statements presented. For a discussion and analysis of fiscal year ended December 31, 2022 and of changes from the fiscal year ended December 31, 2023 to the fiscal year ended December 31, 2022, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (filed with the SEC on March 13, 2024).

Overview

The Company is a building systems solution firm that partners with building owners and facilities managers with mission critical mechanical (heating, ventilation and air conditioning), electrical, and plumbing infrastructure. The Company strives to be an indispensable partner to its customers by providing services that are essential to the operation of their businesses. The Company has approximately 1,400 team members in 20 offices across the eastern United States. The Company’s team members uniquely combine engineering expertise with field installation skills to provide custom solutions that leverage its full life-cycle capabilities, which allows it to address both the operational and capital projects needs of its customers.

The Company’s core market sectors consist of the following customer base with mission-critical systems:

• Healthcare, including research, acute care and inpatient hospitals for regional and national hospital groups;
• Industrial and manufacturing, including automotive, energy and general manufacturing plants;
• Data centers, including facilities composed of networked computers, storage systems and computing infrastructure that organizations use to assemble, process, store and disseminate large amounts of data;
• Life sciences, including organizations and companies whose work is centered around research and development focused on living things;
• Higher education, including both public and private colleges, universities and research centers; and
• Cultural and entertainment, including entertainment facilities (including casinos) and amusement rides and parks.

The Company operates in two segments, (i) ODR, in which the Company performs owner direct projects and/or provides maintenance or service primarily on mechanical, plumbing or electrical systems, building controls and specialty contracting projects to existing buildings direct to, or assigned by, building owners or property managers, and (ii) GCR, in which the Company generally manages new construction or renovation projects that involve primarily mechanical, plumbing, or electrical services awarded to the Company by general contractors or construction managers.

Key Components of Consolidated Statements of Operations

Revenue

The Company generates revenue principally from fixed-price construction contracts to deliver mechanical, plumbing, and electrical construction services to its customers. The duration of the Company’s contracts generally ranges from three months to two years. Revenue from fixed price contracts is recognized on the cost-to-cost method, measured by the relationship of total cost incurred to total estimated contract costs. Revenue from time and materials service contracts is recognized as services are performed. The Company believes that its extensive experience in mechanical, plumbing, and electrical projects, and its internal cost review procedures during the bidding process enable it to reasonably estimate costs and mitigate the risk of cost overruns on fixed price contracts.

The Company generally invoices customers on a monthly basis, based on a schedule of values that breaks down the contract amount into discrete billing items. Costs and estimated earnings in excess of billings are recorded as a contract asset until billable under the contract terms. Billings in excess of costs and estimated earnings are recorded as a contract liability until the related revenue is recognizable.

Cost of Revenue

Cost of revenue primarily consists of labor, equipment, material, subcontract and other job costs in connection with fulfilling the terms of the Company’s contracts. Labor costs consist of wages plus taxes, fringe benefits and insurance. Equipment costs consist of the ownership and operating costs of company-owned assets, in addition to outside-rented equipment. If applicable, job costs include estimated contract losses to be incurred in future periods. Due to the varied nature of the Company's services, and the risks associated therewith, contract costs as a percentage of contract revenue have historically fluctuated, and this fluctuation is expected to continue in future periods as well.

Selling, General and Administrative

Selling, general and administrative (“SG&A”) expenses consist primarily of personnel costs for the Company’s administrative, estimating, human resources, safety, information technology, legal, finance and accounting team members and executives. Also included in SG&A expenses are non-personnel costs, such as travel-related expenses, legal and other professional fees and other corporate expenses to support the growth of the Company's business and to meet the compliance requirements associated with operating as a public company. Those costs include accounting, human resources, information technology, legal personnel, additional consulting, legal and audit fees, insurance costs, Board of Directors’ compensation and the costs of achieving and maintaining compliance with Section 404 of the Sarbanes-Oxley Act of 2002.

Change in fair value of contingent consideration

The change in fair value of contingent consideration relates to the remeasurement of the contingent consideration arrangements resulting from each of the Jake Marshall, LLC (“JMLLC”), Coating Solutions, LLC (“CSLLC”, together with JMLLC, the “Jake Marshall Transaction”), the ACME Transaction, the Industrial Air Transaction, the Kent Island Transaction and the Consolidated Mechanical Transaction. As part of the total consideration for the Jake Marshall, ACME, Industrial Air, Kent Island and Consolidated Mechanical transactions, the Company initially recognized $3.1 million, $1.5 million, $3.2 million, $4.4 million and $0.8 million, respectively, in contingent consideration associated with their respective earnout payments. The carrying values of the Jake Marshall, ACME, Industrial Air, Kent Island and Consolidated Mechanical earnout payments are subject to remeasurement at fair value at each reporting date through the end of the respective earnout periods with any changes in the fair value reported as a separate component of operating income in the consolidated statements of operations. See Note 9 – Fair Value Measurements in the accompanying notes to the Company’s consolidated financial statements for further information.

Amortization of Intangibles

Amortization expense represents periodic non-cash charges that consist of amortization of various intangible assets primarily including favorable leasehold interests and certain customer relationships. As a result of the Jake Marshall Transaction, the Company recognized, in the aggregate, an additional $5.7 million of intangible assets associated with customer relationships with third-party customers, the acquired trade name and acquired backlog. As a result of the ACME Transaction, the Company recognized, in the aggregate, an additional $2.8 million of intangible assets associated with customer relationships with third-party customers and the acquired trade name, inclusive of the impact of certain measurement period adjustments. As a result of the Industrial Air Transaction, the Company recognized, in the aggregate, an additional $8.7 million of intangible assets associated with customer relationships with third-party customers, the acquired trade name, trademarks and intellectual property and the acquired backlog. In addition, as a result of the Kent Island Transaction, the Company recognized, in the aggregate, an additional $10.7 million of intangible assets associated with customer relationships with third-party customers, the acquired trade name and the acquired backlog. Lastly, as a result of the Consolidated Mechanical Transaction, the Company recognized, in the aggregate, an additional $10.1 million of intangible assets associated with customer relationships with third-party customers and the acquired trade name.

Each of the Jake Marshall, ACME, Industrial Air, Kent Island and Consolidated Mechanical-related intangible assets were recorded under the acquisition method of accounting at their estimated fair values at the acquisition date. See Note 3 – Acquisitions in the accompanying notes to the Company’s consolidated financial statements for further discussion of the Company’s acquired intangible assets as a result of the Kent Island and Consolidated Mechanical Transactions. In addition, see Note 5 – Goodwill and Intangible Assets in the accompanying notes to the Company’s consolidated financial statements for further information on the Company’s intangible assets.

Other (Expenses) Income

Other (expenses) income consists primarily of interest expense incurred in connection with the Company's debt, a loss associated with the early termination of an operating lease, gains or losses associated with the disposition of property, equipment, changes in fair value of interest rate swaps, losses associated with the early extinguishment of debt and interest income earned from its overnight repurchase agreements, money market investments, U.S. Treasury Bills and the Company's interest rate swap agreement. Deferred financing costs are amortized to interest expense using the effective interest method.

Provision for Income Taxes

The Company is taxed as a C corporation and its financial results include the effects of federal income taxes, which will be paid at the parent level.

The Company’s provision for income taxes (including federal, state and local taxes) is calculated based on the estimated annual effective tax rate. The Company accounts for income taxes in accordance with Accounting Standards Update (“ASC”) Topic 740 - Income Taxes, which requires the use of the asset and liability method. Under this method, deferred tax assets and liabilities and income or expense are recognized for the expected future tax consequences of temporary differences between the financial statement carrying values and their respective tax bases, using enacted tax rates expected to be applicable in the years in which the temporary differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes.

Impact of Acquisitions

In order to provide a more meaningful period-over-period discussion of the Company’s operating results, the Company may discuss amounts generated or incurred (revenues, gross profit, selling, general and administrative expenses, and operating income) from companies acquired. The amounts discussed reflect the acquired companies’ operating results in the current reported period only for the time period these entities were not owned by the Company in the comparable prior reported period.

During 2023, the Company acquired two companies for total cash consideration of $15.3 million, net of cash acquired and inclusive of certain measurement period adjustments. On July 3, 2023, the Company completed an acquisition of Chattanooga, TN-based specialty industrial contractor, ACME, for a purchase price at closing of $5.0 million in cash. The transaction also provided for an earnout of up to $2.5 million potentially being paid out over 2024 and 2025. ACME specializes in performing industrial maintenance, capital project work, and emergency services for specialty chemical and manufacturing customers, and is a leading mechanical solutions provider for hydroelectric producers. On November 1, 2023, the Company completed an acquisition of Greensboro, NC-based specialty mechanical contractor, Industrial Air, for a purchase price at closing of $13.5 million in cash. The transaction also provided for an earnout of up to $6.5 million potentially being paid out over 2025 and 2026. Industrial Air serves industrial customers throughout the Southeast United States and along the Eastern seaboard, focusing on delivering engineered air handling systems, including air condition and air filtration, along with controls systems and maintenance work. In addition, Industrial Air manufactures a wide range of components for air conditioning and filtration systems.

On September 3, 2024, the Company completed an acquisition of Laurel, MD-based specialty mechanical contractor, Kent Island Mechanical, for a purchase price at closing of $15.0 million. The transaction also provided for an earnout of up to $5.0 million potentially being paid out over 2025 and 2026. Kent Island is a leading provider of building systems solutions in the Greater Washington, DC metro area, including suburban Maryland and Northern Virginia. Kent Island excels in designing, engineering, installing, servicing, and maintaining mechanical and plumbing systems for complex facilities. The acquisition expands the Company’s market share within its existing operating footprint, provides further exposure to an attractive customer base and supports the Company's continued ODR growth strategy.

On December 2, 2024, the Company completed an acquisition of Owensboro, Kentucky-based specialty mechanical contractor, Consolidated Mechanical, for a purchase price at closing of $23.0 million. The transaction also provided for an earnout of up to $2.0 million potentially being paid out over 2026 and 2027. Consolidated Mechanical serves the heavy industrial, power and commercial markets. Consolidated Mechanical is a premier provider of mechanical, millwright, steel fabrication, plumbing construction, maintenance, and outage services to owners of complex process systems in the industrial sector. The acquisition extends the Company’s reach into the industrial sector, with new exposure to the power generation, food processing, manufacturing, and metal markets in Kentucky, Illinois and Michigan.

Divestitures

In February 2022, the Company announced its strategic decision to wind down its Southern California operations. The decision was made to better align the Company’s customer geographic focus and to reduce losses related to unprofitable locations. During 2023, the Company executed the closeout phases on its remaining Southern California business unit projects and has fully exited the Southern California region aside from certain operational warranty obligations. However, the Company is party to the terms of a sublease agreement for its leased premises in Southern California through April 2027 and remains obligated under the original lease for such office space in the event the sublessee fails to satisfy its obligations under the sublease agreement. See Note 14 – Leases in the accompanying notes to the Company’s consolidated financial statements for further information on the Southern California Sublease.

Operating Segments

The Company manages and measures the performance of its business in two operating segments: ODR and GCR. Segment information is prepared on the same basis that the Company’s Chief Operating Decision Maker (“CODM”) reviews operating results for the purposes of allocating resources and assessing performance. The Company’s CODM comprises of its President and Chief Executive Officer and Executive Vice President and Chief Financial Officer.

In accordance with ASC Topic 280 – Segment Reporting, the Company has elected to aggregate all of the ODR work performed at branches into one ODR reportable segment and all of the GCR work performed at branches into one GCR reportable segment. All transactions between segments are eliminated in consolidation.

Comparison of Results of Operations For the Years Ended December 31, 2024 and 2023

The following table presents operating results for the years ended December 31, 2024 and 2023 in dollars and expressed as a percentage of total revenue (except as indicated below):

(in thousands except for percentages)

(1) As a percentage of ODR revenue.

(2) As a percentage of GCR revenue.

(3) Included within selling, general and administrative expenses was $5.8 million and $4.9 million of stock-based compensation expense for the year ended December 31, 2024 and 2023, respectively.

Revenue

(in thousands except for percentages)

Total revenue for the year ended December 31, 2024 increased by $2.4 million compared to the year ended December 31, 2023. ODR revenue increased by $83.5 million, or 31.9%, while GCR revenue decreased by $81.1 million, or 31.9%. The increase in year-over-year ODR segment revenue primarily was due to the Company's continued focus on the accelerated growth of its ODR business. In addition, ODR segment revenue increased in the aggregate by approximately $31.5 million due to the ACME and Industrial Air transactions. These entities were not acquired entities of the Company for the full year ending December 31, 2023. The decrease in year-over-year GCR segment revenue was primarily due to the Company’s continued focus on the execution of its mix-shift strategy to ODR. The Kent Island and Consolidated Mechanical transactions did not have a material impact on revenue for the year ended December 31, 2024 due to timing of when these entities were acquired.

Gross Profit

(in thousands except for percentages)

The Company's gross profit for the year ended December 31, 2024 increased by $25.0 million, or 20.9% compared to the year ended December 31, 2023. ODR gross profit increased $31.7 million, or 41.6%, due to the combination of an increase in revenue, higher margins driven by contract mix and as a result of the ACME and Industrial Air transactions. These entities were not acquired entities of the Company for the full year ending December 31, 2023. GCR gross profit decreased $6.7 million, or 15.5%, primarily due to lower revenue despite higher margins. The total gross profit percentage increased from 23.1% for the year ended December 31, 2023 to 27.8% for the year ended December 31, 2024, mainly driven by the mix of higher margin ODR segment work, the Company becoming more selective when pursuing GCR work, and net material gross profit write-ups. The Kent Island and Consolidated Mechanical transactions did not have a material impact on gross profit for the year ended December 31, 2024 due to timing of when these entities were acquired.

The Company recorded revisions in its contract estimates for certain ODR and GCR projects. During the year ended December 31, 2024, the Company recorded material gross profit write-ups on four ODR segment projects for a total of $3.9 million that had a net gross profit impact of $0.5 million or more. During the year ended December 31, 2024, the Company recorded material gross profit write-ups on three GCR projects for a total of $3.3 million and material gross profit write-downs on two GCR projects for a total of $1.4 million.

During the year ended December 31, 2023, the Company recorded a material gross profit write-down on one ODR segment project for a total of $1.0 million that had a net gross profit impact of $0.5 million or more. During the year ended December 31, 2023, the Company recorded material gross profit write-ups of $2.2 million on two GCR projects and material gross profit write-downs on two GCR projects for a total of $1.3 million.

Selling, General and Administrative

(in thousands except for percentages)

The Company's SG&A expense for the year ended December 31, 2024 increased by approximately $9.8 million, or 11.2% compared to the year ended December 31, 2023. The increase in SG&A was primarily due to a $6.5 million increase associated with payroll and incentive related expenses, $4.1 million of collective expenses incurred from the ACME and Industrial Air entities that were not acquired entities of the Company for the full fiscal year 2023, a $0.9 million increase in stock-based compensation expense and a $0.7 million increase for professional services fees. Partly offsetting this increase was a $1.0 million decrease in SG&A related to CEO transition costs recognized in 2023. Additionally, SG&A as a percentage of revenue was 18.7% for the year ended December 31, 2024 and 16.9% for the year ended December 31, 2023.

Change in Fair Value of Contingent Consideration

The change in fair values of the Company’s earnout payment contingent consideration was a loss of $3.8 million and $0.7 million for the years ended December 31, 2024 and 2023, respectively. These increases to the contingent liability were primarily attributable to the probability of meeting the gross profit margins associated with the contingent consideration arrangements for the acquisitions as of December 31, 2024 and 2023.

Amortization of Intangibles

(in thousands except for percentages)

Total amortization expense for the year ended December 31, 2024 increased by approximately $2.8 million compared to the year ended December 31, 2023. As a result of the ACME, Industrial Air and Kent Island transactions, the Company acquired certain intangible assets in which it recognized an increase of approximately $3.1 million of amortization expense year-over-year. See Note 5 – Goodwill and Intangible Assets in the accompanying notes to the Company’s consolidated financial statements for further information on the Company's intangible assets.

Other Income (Expenses)

(in thousands except for percentages)

Total other income for the year ended December 31, 2024 was $1.3 million as compared to total other expenses of $1.2 million for the year ended December 31, 2023. The increase in total other income (expenses) primarily was driven by a $1.0 million increase in interest income related to the Company's overnight repurchase agreements, investments in U.S. Treasury Bills and money market funds. In addition, during the year ended December 31, 2024, the Company recognized a gain of $1.0 million related to the sale of certain property and equipment compared to $0.1 million recognized in 2023. The increase in total other income (expenses) also included a $0.3 million loss on early debt extinguishment recognized during 2023.

Income Taxes

The Company’s income tax provision was $9.1 million and $7.3 million for the years ended December 31, 2024 and 2023, respectively, and it had a 22.7% and 26.1% effective tax rate over those same periods, respectively. The difference between the U.S. federal statutory tax rate and the Company’s effective tax rate year-over-year was primarily due to state income taxes, tax credits, other permanent adjustments and discrete tax items. In particular, the Company’s effective rate for the year ended December 31, 2024 and 2023 were materially impacted by “excess tax benefits on stock-based compensation” recognized discretely during the first quarter of each year. This benefit reduced the effective tax rate by 35.1% and 10.2% for the three months ended March 31, 2024 and 2023 respectively, with the impact varying in prior years. The increase in the 2024 effective rate reduction is primarily related to the higher stock price of the Company resulting in increased tax deductions for the Company upon vesting of equity incentive awards. See also Note 11 – Income Taxes in the accompanying notes to the Company’s consolidated financial statements.

ODR and GCR Backlog Information

The Company refers to its estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue it had recognized under such contracts, as “backlog.” Backlog includes unexercised contract options. The Company’s backlog includes projects that have a written award, a letter of intent, a notice to proceed or an agreed upon work order to perform work on mutually accepted terms and conditions. Additionally, the difference between the Company’s backlog and remaining performance obligations is due to the portion of unexercised contract options that are excluded, under certain contract types, from the Company’s remaining performance obligations as these contracts can be canceled for convenience at any time by the Company or the customer without considerable cost incurred by the customer. In addition to the Company’s backlog, it has a substantial amount of contracts with short lead times that book-and-bill within the same reporting period and are not included in backlog. Additional information related to the Company’s remaining performance obligations is provided in Note 4 — Revenue from Contracts with Customers in the accompanying notes to its consolidated financial statements. See also “Item 1A. Risk Factors — Our contract backlog is subject to unexpected adjustments and cancellations and could be an uncertain indicator of our future earnings.”

The Company’s ODR backlog was $225.3 million and $147.0 million as of December 31, 2024 and 2023, respectively. These amounts reflect unrecognized revenue expected to be recognized over the remaining terms of its service contracts and projects. Based on historical trends, the Company currently estimates that 86% of its ODR backlog as of December 31, 2024 will be recognized as revenue during 2025. The Company believes its ODR backlog increased due to its continued focus on the accelerated growth of its ODR business.

The Company’s GCR backlog was $140.0 million and $186.9 million as of December 31, 2024 and 2023, respectively. Projects are brought into backlog once the Company has been provided a written confirmation of award and the contract value has been established. At any point in time, the Company has a substantial volume of projects that are specifically identified and advanced in negotiations and/or documentation, however those projects are not booked as backlog until the Company has received written confirmation from the owner or the general contractor / construction manager of their intention to award it the contract and they have directed the Company to begin engineering, designing, incurring construction labor costs or procuring needed equipment and material. The Company’s GCR projects tend to be built over a 12- to 24-month schedule depending upon scope and complexity. Most major projects have a preconstruction planning phase, which may require months of planning before actual construction commences. The Company is occasionally employed to deliver a “fast-track” project, where construction commences as the preconstruction planning work continues. As work on the Company’s projects progress, it increases or decreases backlog to take into account its estimate of the effects of changes in estimated quantities, changes in conditions, change orders and other variations from initially anticipated contract revenue, and the percentage of completion of the Company’s work on the projects. Based on historical trends, the Company currently estimates that 72% of its GCR backlog as of December 31, 2024 will be recognized as revenue during 2025. Additionally, the reduction in GCR backlog has been intentional as the Company looks to focus on higher margin projects than it has done historically, as well as its focus on smaller, higher margin owner direct projects.

Market Update

In 2024, the mechanical services industry experienced steady demand across key sectors, driven by continued investment in energy efficiency, infrastructure upgrades and maintenance of aging mechanical systems. However, the industry faced challenges related to economic uncertainty, labor shortages and supply chain volatility. Although the Company has been experiencing strong demand, these industry challenges continue to impact its business. The Company experienced elevated levels of cost inflation during 2023, which has continued into 2024, although at lower levels than those experienced in 2023. These headwinds have been partially mitigated in 2023 and 2024 by pricing actions taken in response to the inflationary cost environment, supply chain productivity improvements and cost savings initiatives. Economic conditions contributed to increases in interest rates during 2023; however, interest rates remained stable in the first half of 2024 and the Federal Reserve reduced its benchmark interest rate by a total of 100 basis points in the second half of 2024. Future interest rate changes would raise or lower the rates the Company pays on its leased fleet vehicles and borrowings under the Second A&R Wintrust Revolving Loan. However, the Company is party to an interest rate swap arrangement to manage the risk associated with a portion of its variable-rate revolving loan. Also, the ongoing conflict between Russia and Ukraine, and the sanctions imposed in response to this conflict, have increased global economic and political uncertainty and the conflict in the Middle East may add to these issues.

While the impact of these factors remains uncertain, the Company continues to evaluate the extent to which they may impact its business, financial condition or results of operations. There can be no assurance that the Company's actions will serve to mitigate such impacts in future periods. In periods of economic uncertainty, businesses and organizations may delay or cancel large capital projects, such as new construction or major mechanical system upgrades. The Company’s service contracts and maintenance work often remain stable or even increase, as customers prioritize maintaining existing systems over capital-intensive replacements. Further, economic downturns may lead to increased competition and pricing pressures, impacting revenue and margins. The Company believes that its diversified service offerings reduce its exposure to market volatility. While the Company believes its remaining performance obligations are firm, and its customers have not provided the Company with indications that they no longer wish to proceed with planned projects, prolonged delays in the receipt of critical equipment could result in the Company's customers seeking to terminate existing or pending agreements. Any of these events could have a material adverse effect on the Company’s business, financial condition and/or results of operations.

Outlook for 2025

The Company focuses on creating value for building owners by developing long-term relationships and becoming an indispensable partner to building owners with mission-critical systems. For 2025, the key objectives of the Company’s strategy are to 1) improve profitability and generate quality growth in its operations by shifting to the ODR segment; 2) expand margins through evolved offerings, and 3) scale the business through acquisitions. To accomplish these objectives, the Company currently is executing the following initiatives:

In focusing on improved profitability and generating quality growth in its operation, the Company has dedicated and continues to dedicate, its resources toward the growth of its ODR segment as the scope of offerings provided within the Company’s ODR segment typically yield higher margins when compared to its GCR segment work. During fiscal year 2023, the Company eclipsed its ODR-related revenue target, generating a 50/50 segment revenue mix. For 2024, the Company further expanded its growth within the ODR segment where it generated 66.6% of total consolidated revenue, achieving its 2024 ODR segment revenue target of 65-70%. The Company believes it maintains a disciplined approach, capable of providing a full life-cycle of engineered solutions and craft expertise enabling it to be a one-stop-shop for building owners. The Company continues to make investments to expand its ODR revenue by increasing the value it can offer to building owners and continues to evaluate areas in which it could expand the breadth of its service offerings to better serve its customers. In addition, the Company continues to expand its owner-direct offerings to include other digital solutions to manage and monitor the performance of building systems, including data analytics, energy consumption and sustainability. These services allow the Company to develop new revenue streams, leveraging its professional services capabilities to support multi-location regional and national customers in core end-markets, and to drive energy retrofit and performance optimization projects for building owners.

In the Company’s GCR segment, its efforts continue to focus on improving project execution and profitability by pursuing opportunities that are smaller in size and shorter in duration than they have been historically, and where it can leverage its captive design and engineering services. The Company believes that it is appropriate in the current contracting environment to reduce risk and exposure to large, complex, non-owner direct projects where the trend has been for such jobs to provide risks that are difficult to mitigate. Currently, management believes the historical industry pricing and associated risks for this type of work does not align with the Company’s stakeholders’ expectations, and therefore, the Company continues to take steps to actively reduce these risks as it looks at future job selection and as it completes current jobs.

The Company continues to focus on expanding its margins by evolving and enhancing its current offerings to building owners. This initiative reflects the Company’s commitment to driving sustainable growth, increasing operational efficiency and delivering greater value to its stakeholders. This evolution is designed to align more closely with current market demands, emerging customer preferences and operational efficiencies, which together contribute to margin expansion. The Company aims to differentiate itself from its competitors by being a one-stop-shop for building owners, capable of providing a full life-cycle of engineered solutions and craft expertise. By meeting diverse customer needs under one roof, the Company deepens customer loyalty. The Company believes that building owners value the convenience and reliability of a single point of contact, which fosters long-term partnerships, reoccurring business and may open doors to larger capital projects. In addition, by evolving its offerings, the Company is able to capture a greater share of the value chain.

Additionally, the Company believes that it can further increase its cash flow and operating income by acquiring strategically synergistic companies that will increase the Company’s geographic footprint, supplement the Company’s current business model, address capability gaps and enhance the breadth of its offerings to better serve its customers. The Company has dedicated and continues to dedicate its resources to seek opportunities to acquire and integrate businesses that have attractive market positions, supports the Company’s ODR growth strategy, expands and/or supplements the Company’s current breadth of offerings and is culturally compatible. See Note 3 – Acquisitions in the accompanying notes to the Company’s consolidated financial statements for further information on the Company’s most recent acquisition activity.

Given the broad suite of offerings to customers within the Company’s market concentrations, management uses a variety of factors to attempt to predict the outlook for the Company. The Company monitors key competitors and customers in order to gauge relative performance and the outlook for the future. The Company regularly performs detailed evaluations of different market verticals in which it serves to proactively detect trends and to adapt its strategies accordingly, including potential triggers and actions to be taken under recessionary scenarios. In addition, the Company believes its backlog is indicative of future revenue and thus are a key measure of anticipated performance.

The Company continues to monitor the impact that the inflationary cost environment has on its cost structure. Although global supply chain and resource constraints have improved throughout the year, the Company’s performance may be impacted by future developments that are uncertain. In addition, geopolitical risks and macroeconomic events could cause disruptions to operations, supply chains and end markets, tightening credit conditions, higher interest rates, global banking uncertainty and the possibility of deteriorating overall economic conditions which could negatively impact the Company’s business.

Seasonality, Cyclicality and Quarterly Trends

Severe weather can impact the Company’s operations. In the northern climates where it operates, and to a lesser extent the southern climates as well, severe winters can slow the Company’s productivity on construction projects, which shifts revenue and gross profit recognition to a later period. The Company’s maintenance operations may also be impacted by mild or severe weather. Mild weather tends to reduce demand for its maintenance services, whereas severe weather may increase the demand for its maintenance and time-and-materials services. The Company’s operations also experience mild cyclicality, as building owners typically work through maintenance and capital projects at an increased level during the third and fourth calendar quarters of each year.

Effect of Inflation and Tariffs

The prices of products such as steel, pipe, copper and equipment from manufacturers are subject to fluctuation and increases. It is difficult to accurately measure the impact of inflation, tariffs and price escalation due to the imprecise nature of the estimates required. However, these effects are, at times, material to the Company’s results of operations and financial condition. During fiscal years 2023 and 2022, the Company experienced higher cost of materials on specific projects and delays in its supply chain for equipment and service vehicles from the manufacturers, and these higher costs and delays in its supply chain persisted in 2024. When appropriate, the Company includes cost escalation factors into its bids and proposals, and limits the acceptance time of its bid. In addition, the Company is often able to mitigate the impact of future price increases by entering into fixed price purchase orders for materials and equipment and subcontracts on its projects. Notwithstanding these efforts, if the Company experiences significant disruptions to its supply chain, it may need to delay certain projects that would otherwise be accretive to its business, and this may also impact the conversion rate of its current backlog into revenue.

In February 2025, the United States government announced a number of tariffs on imports, including imports on steel and aluminum. Increased costs for imported steel and aluminum products have led domestic sellers to respond with market-based increases to prices for such inputs as well. These tariffs, along with any additional tariffs or trade restrictions that may be implemented by the United States or other countries, could result in further increased costs, shifts in competitive positions and a decreased supply of steel, resins and aluminum as well as additional imported components and materials. The Company’s ODR segment focus often allows for these increased costs to be passed onto the customer due to the short sales cycle; however, the Company may not be able to pass certain price increases on to its customers and may not be able to secure adequate alternative sources of materials on a timely basis. The Company may not be able to pass certain price increases on to its customers and may not be able to secure adequate alternative sources of materials on a timely basis. While retaliatory tariffs imposed by other countries on the United States have not yet had a significant impact, the Company cannot predict further developments. At this time, it is difficult to accurately measure the impact these tariffs, or potential future tariffs, will have on the Company.

Liquidity and Capital Resources

Cash Flows

The Company’s liquidity needs relate primarily to the provision of working capital (defined as current assets less current liabilities) to support operations, funding of capital expenditures, and investment in strategic opportunities. Historically, liquidity has been provided by operating activities and borrowings from commercial banks and institutional lenders.

The following table presents summary cash flow information for the periods indicated:

(in thousands)

The Company's cash flows are primarily impacted period to period by fluctuations in working capital. Factors such as the Company’s contract mix, commercial terms, days sales outstanding (“DSO”) and delays in the start of projects may impact its working capital. In line with industry practice, the Company accumulates costs during a given month then bills those costs in the current month for many of its contracts. While labor costs associated with these contracts are paid weekly and salary costs associated with the contracts are paid bi-weekly, certain subcontractor costs are generally not paid until the Company receives payment from its customers (contractual “pay-if-paid” terms). The Company has not historically experienced a large volume of write-offs related to its receivables and contract assets. The Company regularly assesses its receivables for collectability and provides allowances for credit losses where appropriate. The Company believes that its reserves for its expected credit losses are appropriate as of December 31, 2024, but adverse changes in the economic environment may impact certain of its customers’ ability to access capital and compensate the Company for its services, as well as impact project activity for the foreseeable future.

The Company’s existing current backlog is projected to provide substantial coverage of forecasted revenue for one year from the date of the financial statement issuance. In addition to the Company's backlog, it has a substantial amount of contracts with short lead times that book-and-bill within the same reporting period and are not included in backlog. The Company's current cash balance, together with cash it expects to generate from future operations, along with borrowings available under its credit facility, are expected to be sufficient to finance its short- and long-term capital requirements (or meet working capital requirements) for at least the next twelve months. In addition to the future operating cash flows of the Company, along with its existing borrowing availability and access to financial markets, the Company currently believes it will be able to meet any working capital and future operating requirements, and capital investment forecast opportunities for at least the next twelve months.

The following table represents the Company’s summarized working capital information:

(in thousands, except ratios)

(1) Current ratio is calculated by dividing current assets by current liabilities.

As discussed above and in Note 7 – Debt in the accompanying notes to the Company’s consolidated financial statements, as of December 31, 2024, the Company was in compliance with all financial maintenance covenants as required by its credit facility.

Cash Flows Provided by Operating Activities

The following is a summary of the significant sources (uses) of cash from operating activities:

(in thousands)

(1) Represents non-cash activity associated with depreciation and amortization, provision for credit losses, stock-based compensation expense, operating lease expense, amortization of debt issuance costs, deferred income tax provision, gain or loss on sale of property and equipment, changes in fair value of contingent consideration and changes in the fair value of the Company’s interest rate swap.

During the year ended December 31, 2024, the Company generated $36.8 million in cash in its operating activities, which consisted of cash used in working capital of $18.5 million, non-cash adjustments of $24.5 million (primarily depreciation and amortization, stock-based compensation expense, operating lease expense and the change in fair value of contingent consideration) and net income for the period of $30.9 million. During the year ended December 31, 2023, the Company generated $57.4 million in cash in its operating activities, which consisted of cash provided by working capital of $18.4 million, non-cash adjustments of $18.2 million (primarily depreciation and amortization, stock-based compensation expense, operating lease expense, loss on early debt extinguishment and the change in fair value of contingent consideration) and net income for the period of $20.8 million.

The decrease in operating cash flows during the year ended December 31, 2024 compared to the year ended December 31, 2023 was primarily attributable to a $43.9 million year-over-year cash outflow related to the change in accounts receivable, which was due to the timing of cash receipts and the successful resolution of certain outstanding claims recognized in 2023. This cash outflow was partially offset by a $10.1 million increase in net income, a $6.2 million increase related to non-cash operating activities and an aggregate $4.3 million period-over-period change related to the Company’s contract assets and liabilities. The increase in the Company’s overbilled position was due to the timing of contract billings and the recognition of contract revenue.

Cash Flows Used in Investing Activities

Cash flows used in investing activities were $42.6 million for the year ended December 31, 2024 as compared to $17.1 million for the year ended December 31, 2023. Cash used in investing activities for the year ended December 31, 2024 included cash outflows of $13.4 million and $23.2 million cash outflows associated with the Kent Island Transaction and Consolidated Mechanical Transaction, respectively, net of cash acquired and inclusive of certain measurement period adjustments. In addition, cash used in investing activities for the year ended December 31, 2024 represented $7.5 million of cash outflows for capital additions pertaining to purchased property and equipment, which was primarily associated with the purchase of certain rental equipment to expand customer offerings. During fiscal year 2024, the Company began offering direct rental equipment solutions for building owners who are faced with unexpected disruptions or a planned maintenance or system repair, ensuring minimal downtime for customers’ systems and facilities. These cash outflows were partially offset by $1.5 million in proceeds from the sale of property and equipment. Cash used in investing activities for the year ended December 31, 2023 included cash outflows of $4.9 million and $10.4 million associated with the ACME Transaction and Industrial Air Transaction, respectively, net of cash acquired and inclusive of certain measurement period adjustments. In addition, cash used in investing activities for the year ended December 31, 2023 represented $2.3 million of cash outflows for capital additions pertaining to purchased property and equipment, offset by $0.4 million in cash proceeds from the sale of property and equipment.

Aside from the rental equipment purchased during 2024, the majority of the Company's purchases of property and equipment in both periods was for capital additions pertaining to tools and equipment, computer software and hardware purchases, office furniture and office related leasehold improvements. For the years ended December 31, 2024 and 2023, the Company obtained the use of various assets through operating and finance leases, which reduced the level of capital expenditures that would have otherwise been necessary to operate its business.

Cash Flows Used in Financing Activities

Cash flows used in financing activities were $9.1 million for the year ended December 31, 2024 as compared to cash flows provided by financing activities of $16.5 million for the year ended December 31, 2023. For the year ended December 31, 2024, the Company paid approximately $5.2 million in taxes related to the net share settlement of equity awards, $3.0 million for payments on finance leases and made $3.5 million in aggregate payments to the former owners of JMLLC, CSLLC and ACME related to their respective 2023 earnout arrangements, of which $1.3 million was recognized as a cash outflow from financing activities. These cash financing outflows were partially offset by $0.4 million associated with proceeds from employee contributions to the Company’s Employee Stock Purchase Plan (“ESPP”).

For the year ended December 31, 2023, as a result of the execution of the Second A&R Wintrust Credit Agreement, the Company paid off the remaining principal portion of the A&R Wintrust Term Loan of $19.0 million. Prior to the termination of the A&R Wintrust Term Loan, the Company made principal payments of $2.4 million, consisting of monthly installment payments of $0.6 million. In addition, the Company paid approximately $0.8 million in taxes related to net share settlement of equity awards, $2.7 million for payments on finance leases and made a $3.0 million payment to the former owners of JMLLC and CSLLC related to the 2022 Jake Marshall Earnout Period, of which $1.8 million was recognized as a cash outflow from financing activities. These cash financing outflows were partially offset by $10.0 million in proceeds from borrowings under the Second A&R Wintrust Revolving Loan and $0.4 million associated with proceeds from contributions to the Company’s ESPP.

The following table reflects the Company’s available funding capacity as of December 31, 2024:

Debt and Related Obligations

Long-term debt consists of the following obligations as of:

(in thousands)

See Note 7 – Debt in the accompanying notes to the Company’s consolidated financial statements for further discussion.

Material Cash Requirements from Contractual and Other Obligations

As of December 31, 2024, the Company’s short-term and long-term material cash requirements for known contractual and other obligations were as follows:

Outstanding Debt and Interest Payments: As of December 31, 2024, the Company had $10.0 million of direct borrowings outstanding under its Second A&R Wintrust Revolving Loan. The Second A&R Wintrust Revolving Loan bears interest, at LFS’s option, at either the Term SOFR (as defined in the Second A&R Credit Agreement) (with a 0.15% floor) plus 3.10% or the Prime Rate (as defined in the Second A&R Credit Agreement) (with a 3.0% floor), subject to a 50 basis point step-down based on the ratio between the senior debt of the Company and its subsidiaries to the EBITDA of LFS and its subsidiaries for the most recently ended four fiscal quarters. Interest payments on any future borrowings will be determined based on prevailing rates at that time. The Company is party to an interest rate swap arrangement to manage the risk associated with a portion of it variable-rate long-term debt. The Second A&R Wintrust Revolving Loan will mature in February 2028. See Note 7 – Debt in the accompanying notes to the Company’s consolidated financial statements for further detail of the Company’s debt obligations, including the Company’s revolving credit facility.

Sale-Leaseback Financing Transaction: In fiscal year ended December 31, 2022, the Company executed a sale-leaseback financing transaction with respect to its branch facility in Pontiac, Michigan to provide additional liquidity. Future payments associated with the sale-leaseback financing transaction were $15.9 million at December 31, 2024, with $0.5 million payable within the next 12 months. See Note 7 – Debt in the accompanying notes to the Company’s consolidated financial statements for further detail surrounding the Company’s sale-leaseback financing transaction.

Operating and Finance Leases: In the normal course of business, the Company leases real estate, vehicles and other equipment under various arrangements which are classified as either operating or finance leases. Future payments for such leases, excluding leases with initial terms of one year or less, were $39.2 million at December 31, 2024, with $9.1 million payable within the next 12 months. See Note 14 – Leases in the accompanying notes to the Company’s consolidated financial statements for further detail surrounding the Company’s lease obligations and the timing of expected future payments.

Contingent Consideration Liabilities: The Company has incurred liabilities related to contingent consideration arrangements associated with certain acquisitions, payable in the event discrete performance objectives are achieved by the acquired businesses during designated post-acquisition periods. The aggregate amount of these liabilities can change due to additional business acquisitions, settlement of outstanding liabilities, changes in the fair value of amounts owed based on performance during such post-acquisition periods, and accretion in present value. As of December 31, 2024, the present value of expected future payments relating to these contingent consideration arrangements was $13.2 million. Of this amount, $7.4 million is estimated as being payable during 2025, with the remainder due in 2026 and 2027. See Note 9 – Fair Value Measurements in the accompanying notes to the Company’s consolidated financial statements for more information regarding the Company’s contingent consideration liabilities.

Open Purchase Obligations: As of December 31, 2024, the Company had $91.2 million of open purchase obligations, of which approximately $73.0 million are expected to become due within the next 12 months. These obligations represent open purchase orders to suppliers and subcontractors related to the Company’s projects and services contracts. These purchase orders are not reflected in the consolidated balance sheets and are not expected to impact future liquidity as amounts should be recovered through customer billings.

In addition, material cash requirements for other potential obligations, for which we cannot reasonably estimate future payments, include the following:

Legal Proceedings: The Company is continually engaged in administrative proceedings, arbitrations, and litigation with owners, general contractors, suppliers, team members, former team members and other unrelated parties, all arising in the ordinary courses of business. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the consolidated financial statements. In the opinion of the Company’s management, the results of these actions will not have a material adverse effect on the financial position, results of operations, or cash flows of the Company. See Note 13 – Commitments and Contingencies in the accompanying notes to the Company’s consolidated financial statements for more information regarding legal proceedings.

Multiemployer Pension Plans: In addition to the Company’s sponsored benefit plans, the Company participates in certain multiemployer pension and other post-retirement plans. The cost of these plans is equal to the annual required contributions determined in accordance with the provisions of negotiated collective bargaining agreements. During 2024 and 2023, contributions made to these plans were $10.3 million and $11.6 million, respectively; however, the Company’s future contributions to the multiemployer plans are dependent upon a number of factors. Amounts of future contributions that the Company would be contractually obligated to make pursuant to these plans cannot be reasonably estimated. See Note 16 – Multiemployer Pension Plans in the accompanying notes to the Company’s consolidated financial statements for more information regarding these multiemployer pension plans.

Surety Bonding

In connection with its business, the Company is occasionally required to provide various types of surety bonds that provide an additional measure of security to its customers for its performance under certain government and private sector contracts. The Company’s ability to obtain surety bonds depends upon its capitalization, working capital, past performance, management expertise and external factors, including the capacity of the overall surety market. Surety companies consider such factors in light of the amount of the Company’s backlog that it has currently bonded and their current underwriting standards, which may change from time-to-time. The bonds the Company provides, if any, typically reflect the contract value. As of December 31, 2024 and 2023, the Company has approximately $109.3 million and $90.9 million, respectively, in surety bonds outstanding. The Company believes that its $800 million bonding capacity provides it with a significant competitive advantage relative to many of its competitors which have limited bonding capacity. See Note 13 – Commitments and Contingencies in the accompanying notes to the Company’s consolidated financial statements for further discussion.

Insurance and Self-Insurance

The Company purchases workers’ compensation and general liability insurance under policies with per-incident deductibles of $250,000 per occurrence. Losses incurred over primary policy limits are covered by umbrella and excess policies up to specified limits with multiple excess insurers. The Company accrues for the unfunded portion of costs for both reported claims and incurred but not reported claims. The liability for unfunded reported claims and future claims is reflected on the consolidated balance sheets as current and non-current liabilities. The liability is computed by determining a reserve for each reported claim on a case-by-case basis based on the nature of the claim and historical loss experience for similar claims plus an allowance for the cost of incurred but not reported claims. The current portion of the liability is included in accrued expenses and other current liabilities on the consolidated balance sheets. The non-current portion of the liability is included in other long-term liabilities on the consolidated balance sheets.

The Company is self-insured related to medical and dental claims under policies with annual per-claimant and annual aggregate stop-loss limits. The Company accrues for the unfunded portion of costs for both reported claims and incurred but not reported claims. The liability for unfunded reported claims and future claims is reflected on the consolidated balance sheets as a current liability in accrued expenses and other current liabilities. See Note 13 – Commitments and Contingencies in the accompanying notes to the Company’s consolidated financial statements for further discussion.

Multiemployer Plans

The Company participates in approximately 50 MEPPs that provide retirement benefits to certain union team members in accordance with various collective bargaining agreements (“CBAs”). As one of many participating employers in these MEPPs, the Company is responsible with the other participating employers for any plan underfunding. The Company’s contributions to a particular MEPP are established by the applicable CBAs; however, required contributions may increase based on the funded status of an MEPP and legal requirements of the Pension Protection Act of 2006 (the “PPA”), which requires substantially underfunded MEPPs to implement a funding improvement plan (“FIP”) or a rehabilitation plan (“RP”) to improve its funded status. Factors that could impact funded status of an MEPP include, without limitation, investment performance, changes in the participant demographics, decline in the number of contributing employers, changes in actuarial assumptions and the utilization of extended amortization provisions. Assets contributed to the MEPPs by the Company may be used to provide benefits to team members of other participating employers. If a participating employer stops contributing to an MEPP, the unfunded obligations of the MEPP may be borne by the remaining participating employers.

An FIP or RP requires a particular MEPP to adopt measures to correct its underfunding status. These measures may include, but are not limited to an increase in a company’s contribution rate as a signatory to the applicable CBA, or changes to the benefits paid to retirees. In addition, the PPA requires that a 5.0% surcharge be levied on employer contributions for the first year commencing shortly after the date the employer receives notice that the MEPP is in critical status and a 10.0% surcharge on each succeeding year until a CBA is in place with terms and conditions consistent with the RP.

The Company could also be obligated to make payments to MEPPs if it either ceases to have an obligation to contribute to the MEPP or significantly reduces its contributions to the MEPP because it reduces the number of team members who are covered by the relevant MEPP for various reasons, including, but not limited to, layoffs or closure of a subsidiary assuming the MEPP has unfunded vested benefits. The amount of such payments (known as a complete or partial withdrawal liability) would equal the Company’s proportionate share of the MEPPs’ unfunded vested benefits. The Company believes that certain of the MEPPs in which it participates may have unfunded vested benefits. Due to uncertainty regarding future factors that could trigger withdrawal liability, the Company is unable to determine (a) the amount and timing of any future withdrawal liability, if any, and (b) whether its participation in these MEPPs could have a material adverse impact on its financial condition, results of operations or liquidity. See Note 16 – Multiemployer Pension Plans in the accompanying notes to the Company’s consolidated financial statements for further discussion.

Recent Accounting Pronouncements

The Company reviews new accounting standards to determine the expected financial impact, if any, that the adoption of such standards will have on its financial position and/or results of operations. See Note 2 – Significant Accounting Policies in the accompanying notes to the Company’s consolidated financial statements for further information regarding new accounting standards, including the anticipated dates of adoption and the effects on its consolidated financial position, results of operations, or liquidity.

Critical Accounting Policies

The Company’s critical accounting policies are based upon the significance of the accounting policy to its overall financial statement presentation, as well as the complexity of the accounting policy and its use of estimates and subjective assessments. The Company’s most critical accounting policy is revenue recognition. As discussed elsewhere in this Annual Report on Form 10-K, the Company’s business has two operating segments: (i) ODR, for which it accounts for using the cost-to-cost method and for certain projects when revenue is recognized as services are provided and (ii) GCR, for which it accounts for using the cost-to-cost method. In addition, the Company believes that some of the more critical judgment areas in the application of accounting policies that affect its financial condition and results of operations are the impact of changes in the estimates and judgments pertaining to: (a) collectability or valuation of accounts receivable; (b) the recording of its self-insurance liabilities; (c) valuation of deferred tax assets; and (d) recoverability of goodwill and identifiable intangible assets. These accounting policies, as well as others, are described in Note 2 – Significant Accounting Policies in the accompanying notes to the Company’s consolidated financial statements.

Revenue and Cost Recognition

The Company believes its most significant accounting policy is revenue recognition from construction contracts for which it uses the cost-to-cost method of accounting. Under the cost-to-cost method, contract revenue recognizable at any time during the life of a contract is determined by multiplying expected total contract revenue by the percentage of contract costs incurred to total estimated contract costs. Revenue from fixed price and modified fixed price contracts are recognized on the cost-to-cost method, measured by the relationship of total cost incurred to total estimated contract costs.

Contract costs include direct labor, material, and subcontractor costs, and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, depreciation, and insurance. These contract costs are included in the Company’s results of operations under the caption “Cost of Revenue.” Then, as the Company performs under those contracts, it measures costs incurred, compares them to total estimated costs to complete the contract, and recognizes a corresponding proportion of contract revenue. Labor costs are considered to be incurred as the work is performed. Subcontractor labor is recognized as the work is performed but is generally subjected to approval as to milestones or other evidence of completion. Non-labor project costs consist of purchased equipment, prefabricated materials and other materials. Purchased equipment on the Company’s projects is substantially produced to job specifications and is a value-added element to its work. The costs are considered to be incurred when title is transferred to the Company, which typically is upon delivery to the worksite. Prefabricated materials, such as ductwork and piping, are generally performed at the Company’s shops and recognized as contract costs when fabricated for the unique specifications of the job. Other materials costs are not significant and are generally recorded when delivered to the worksite. This measurement and comparison process requires updates to the estimate of total costs to complete the contract, and these updates may include subjective assessments.

The Company generally does not incur significant costs prior to receiving a contract, and therefore, these costs are expensed as incurred. Upon receiving the contract, these costs are included in contract costs. Selling, general, and administrative costs are charged to expense as incurred. Bidding and proposal costs are also recognized as expenses in the period in which such amounts are incurred. Total estimated contract costs are based upon management’s current estimate of total costs at completion. As changes in estimates of contract costs at completion and/or estimated total losses on projects are identified, appropriate earnings adjustments are recorded during the period that the change or loss is identified. Contract revenue for construction contracts is based upon management’s estimate of contract prices at completion, including revenue for additional work on which contract pricing has not been finalized (claims). Changes in job performance, job conditions and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to estimated costs and income, and are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are recognized in the period in which such losses are determined.

With respect to the Company’s service contracts, there are two basic types of service contracts: fixed price service contracts, which are signed in advance for maintenance, repair and retrofit work over a period, typically of one year, and service contracts, which are not signed in advance for similar maintenance, repair and retrofit work on an as-needed basis. Fixed price service contracts are generally performed evenly over the contract period, and accordingly, revenue is recognized on a pro rata basis over the life of the contract. Revenue derived from other service contracts is recognized when the services are performed. Expenses related to all service contracts are recognized as services are provided.

Project contracts typically provide for a schedule of billings or invoices to the customer based on reaching agreed upon milestones or as the Company incurs costs. The schedules for such billings usually do not precisely match the schedule on which costs are incurred. As a result, contract revenue recognized in the statement of operations can and usually does differ from amounts that can be billed or invoiced to the customer at any point during the contract. Amounts by which cumulative contract revenue recognized on a contract as of a given date exceed cumulative billings to the customer under the contract are reflected as a current asset in the Company’s balance sheet under the caption “contract assets.” Amounts by which cumulative billings to the customer under a contract as of a given date exceed cumulative contract revenue recognized on the contract are reflected as a current liability in the Company’s balance sheet under the caption “contract liabilities.”

The cost-to-cost method of accounting is also affected by changes in job performance, job conditions, and final contract settlements. These factors may result in revisions to estimated costs and, therefore, revenue. Such revisions are frequently based on further estimates and subjective assessments. The effects of these revisions are recognized in the period in which revisions are determined. When such revisions lead to a conclusion that a loss will be recognized on a contract, the full amount of the estimated ultimate loss is recognized in the period such conclusion is reached, regardless of the percent complete of the contract.

Revisions to project costs and conditions can give rise to change orders under which the customer agrees to pay additional contract price. Revisions can also result in claims the Company might make against the customer to recover project variances that have not been satisfactorily addressed through change orders with the customer. Claims and unapproved change orders are recorded at estimated net realizable value when realization is probable and can be reasonably estimated. No profit is recognized on the construction costs incurred in connection with claim amounts. See Note 4 – Revenue from Contracts with Customers in the accompanying notes to the Company’s consolidated financial statements for information related to unresolved change orders and claims.

Variations from estimated project costs could have a significant impact on the Company’s operating results, depending on project size, and the recoverability of the variation via additional customer payments.

In accordance with industry practice, the Company classifies as current all assets and liabilities relating to the performance of long-term contracts. The term of the Company’s contracts generally ranges from three months to two years and, accordingly, collection or payment of amounts relating to these contracts may extend beyond one year.

Accounts Receivable and Allowance for Credit Losses

On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The Company develops its allowance for credit losses, which represents an estimate of expected losses over the remaining contractual life of its receivables, using an aging method. Under the aging method, the Company assigns its accounts receivable to a level of delinquency and apply loss rates to each class. The determination of its loss rates require it to make certain judgements and estimates involving, among others, the creditworthiness of its customers, historical loss experiences with customers, the aging of past due balances, the consideration of a customer’s financial condition, ongoing relationships with its customers, its lien rights, if any, in the property where it performed the work, the availability, if any, of payment bonds applicable to the contract, current market economic conditions and a forecast of future economic conditions when appropriate. These estimates are evaluated and adjusted as needed when additional information is received.

Self-Insurance Liabilities

The Company is substantially self-insured for workers’ compensation, employer’s liability, auto liability, general liability and employee group health claims in view of the relatively high per-incident deductibles it absorbs under its insurance arrangements for these risks. Losses are estimated and accrued based upon known facts, historical trends and industry averages. Estimated losses in excess of the Company’s deductible, which have not already been paid, are included in the Company’s accrual with a corresponding receivable from its insurance carrier.

In addition, the Company is self-insured related to medical and dental claims under policies with annual per-claimant and annual aggregate stop-loss limits. The Company accrues for the unfunded portion of costs for both reported claims and claims incurred but not reported.

The Company believes the liabilities recognized on its balance sheets for these obligations are adequate. However, insurance liabilities are difficult to estimate due to unknown factors, including the severity of any injury, the determination of its liability in proportion to other parties, timely reporting of occurrences, ongoing treatment or loss mitigation, general trends in litigation recovery outcomes and the effectiveness of safety and risk management programs. Therefore, if actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and would be recorded in the period that such experience becomes known.

Deferred Tax Assets

The Company regularly evaluates the need for valuation allowances related to deferred tax assets for which future realization is uncertain. The Company performs this evaluation quarterly. In assessing the realizability of deferred tax assets, it must consider whether it is more likely than not some portion, or all, of the deferred tax assets will not be realized. The Company considers all available evidence, both positive and negative, in determining whether a valuation allowance is required. Such evidence includes the scheduled reversal of deferred tax liabilities, projected future taxable income, taxable income in prior carryback years and tax planning strategies in making this assessment, and judgment is required in considering the relative weight of negative and positive evidence.

Goodwill and Identifiable Intangible Assets

Goodwill is the excess of purchase price over the fair value of the net assets of acquired businesses. The Company assesses goodwill for impairment each year, and more frequently if circumstances suggest an impairment may have occurred. When the carrying value of a given reporting unit exceeds its fair value, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value. If other reporting units have had increases in fair value, such increases may not be recorded. Accordingly, such increases may not be netted against impairments at other reporting units. The requirements for assessing whether goodwill has been impaired involve market-based information. This information, and its use in assessing goodwill, entails some degree of subjective assessment.

The Company performs its annual impairment testing as of October 1 every year, and any impairment charges resulting from this process are reported in the fourth quarter. The Company segregates its operations into reporting units based on the degree of operating and financial independence of each unit and its related management of them. The Company performs its annual goodwill impairment analysis at the reporting unit level. Each of the Company’s operating units represents an operating segment, and its operating segments are its reporting units.

The Company also reviews intangible assets with definite lives subject to amortization whenever events or circumstances indicate that a carrying amount of an asset may not be recoverable. Events or circumstances that might require impairment testing include the identification of other impaired assets within a reporting unit, loss of key personnel, the disposition of a significant portion of a reporting unit, a significant decline in stock price or a significant adverse change in business climate or regulations. Changes in strategy and/or market condition may also result in adjustments to recorded intangible asset balances or their useful lives.

Off-Balance Sheet and Other Arrangements

Aside from the $4.2 million and $4.1 million in irrevocable letters of credit outstanding in connection with the Company’s self-insurance program, at December 31, 2024 and 2023, respectively, the Company did not have any relationships with any entities or financial partnerships, such as structured finance or special purpose entities established for the purpose of facilitating off-balance sheet arrangements or other purposes.

Interest Rate Risk

The Company is exposed to market risk through changes in interest rates, primarily limited to borrowings under its Second A&R Wintrust Revolving Loan in excess of the amounts covered by the Company’s interest rate swap arrangement. As of December 31, 2024, the Company had $10.0 million of direct borrowings outstanding under its Second A&R Wintrust Revolving Loan. The Company is party to an interest rate swap arrangement to manage the risk associated with a portion of its variable-rate long-term debt. The interest rate swap has a $10.0 million notional value with a fixed interest rate and will mature in July 2027. The Company has not designated this instrument as a hedge for accounting purposes. As a result, the change in fair value of the derivative instrument is recognized directly in earnings on the Company's consolidated statements of operations as a gain or loss on interest rate swap. Assuming outstanding balances were to remain the same and including the impact of the Company’s interest rate swap agreement, an increase or decrease in interest rates would not have a material impact on the Company’s consolidated statements of operations. See Note 7 – Debt in the accompanying notes to the Company’s consolidated financial statements for further detail of the Company’s revolving credit facility and interest rate swap arrangement.

In addition, the Company considers all highly liquid investments purchased with a maturity of 90 days or less on the date of purchase to be cash equivalents. Cash equivalents as of December 31, 2024 were $43.0 million, which consisted of overnight repurchase agreements in which cash from the Company's main operating checking account is invested overnight in highly liquid, short term investments and certain investments in money market funds sponsored by a large financial institution. For the year ended December 31, 2024, the Company recognized interest income in the aggregate of approximately $2.2 million. The Company maintains a conservative investment policy and has not experienced any losses in its cash and cash equivalents. Management believes the Company is not exposed to significant risk with respect to such accounts.

Evaluation of Disclosure Controls and Procedures: Our management carried out, as of December 31, 2024, with the participation of our President and Chief Executive Officer and our Executive Vice President and Chief Financial Officer, an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on that evaluation, our President and Chief Executive Officer and Executive Vice President and Chief Financial Officer concluded that, as of December 31, 2024, our disclosure controls and procedures were effective to provide reasonable assurance that material information required to be disclosed by us in reports we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our President and Chief Executive

Officer and Executive Vice President and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting: There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f)) during the fourth quarter of 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting: Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d -15(f). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with existing policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our President and Chief Executive Officer and Executive Vice President and Chief Financial Officer, our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in “Internal Control-Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2024.
