Item 1A. Risk Factors

Investing in our Class A Common Stock involves risk. In addition to the other information contained in this Annual Report, the following risk factors make an investment in us speculative or risky and should be considered in evaluating our business and future prospects. The risks and uncertainties described below are not the only ones we face. Additional risks not presently known to us or that we currently deem immaterial may also materially affect our business and operations. The occurrence of any of the following risks or additional risks and uncertainties that are currently immaterial or unknown could materially and adversely affect our business, financial condition, liquidity, results of operations, cash flows or prospects. The trading price of our Class A Common Stock could decline due to any of these risks, and you may lose all or part of your investment.

Risks Related to Business

Economic downturns in the markets in which we operate may materially and adversely affect our business because our business is dependent on levels of construction activity.

The demand for our services is dependent upon the existence of construction projects and service requirements within the markets in which we operate. Any period of economic recession affecting a market or industry in which we transact business, such as data centers, is likely to adversely impact our business. Some of the projects we work on may

Table of Conten t s

have long lifecycles from conception to completion, and the bulk of our performance generally occurs late in a construction project’s lifecycle.

The industries and markets in which we operate have been and will continue to be vulnerable to macroeconomic downturns because they are cyclical in nature. When there is a reduction in demand, it often leads to greater price competition as well as decreased revenue and profit. The lasting effects of a recession can also increase economic instability with our vendors, subcontractors, developers and general contractors, which can result in us not being paid in full or at all on some projects, thus decreasing our revenue and profit. Further, to the extent some of our vendors, subcontractors, developers or general contractors seek bankruptcy protection, such bankruptcy will likely force us to incur additional costs in attorneys’ fees, as well as other professional consultants, and will result in decreased revenue and profit. Additionally, a reduction in federal, state or local government spending in our industries and markets could result in decreased revenue and profit for us. As a result, economic downturns in our industry could have a material adverse impact on our business, financial condition and results of operations.

If we do not compete and evolve effectively in our target markets, our operating results could be harmed.

Our industry is highly competitive, with many companies of varying size and business models competing for the same business as we do. Some of our competitors may have greater resources than us and could focus their substantial financial resources to develop a competitive advantage, others may be smaller, have a lower cost structure, employ a non-unionized workforce or be able to adapt to the constantly changing demand of the market more quickly. Our competitors may also offer services at prices below cost, devote significant sales forces to competing with us or attempt to recruit our key personnel by increasing compensation, any of which could improve their competitive positions.

Any of these competitive factors could make it more difficult for us to attract and retain customers, cause us to lower our prices in order to compete, and reduce our market share and revenues, any of which could have a material adverse impact on our business, financial condition and results of operations. We can provide no assurance that we will continue to effectively compete against our current competitors or additional companies that may enter our markets. If our work processes become obsolete, through technological advancements or otherwise, we may not be able to differentiate our service offerings and some of our competitors may be able to offer more attractive services to our customers. We also encounter competition in the form of potential customers electing to develop solutions or perform services internally rather than engaging an outside provider such as us.

Misconduct and errors by our employees, subcontractors, partners or third-party service providers could harm our business.

Misconduct, fraud or other improper activities caused by our employees’, subcontractors’, partners’ or consultants’ failure to comply with laws or regulations could have a significant negative impact on our business. Such misconduct could include the failure to comply with procurement regulations or procedures, environmental, health and safety regulations, laws or procedures regarding the protection of sensitive information, legislation regarding the pricing of labor and other costs in government contracts, regulations on lobbying or similar activities, and anti-corruption, anti-competition and other applicable laws or regulations. Our failure to comply with applicable laws, regulations or procedures, misconduct by any of our employees, subcontractors, partners or consultants, or our failure to make timely and accurate certifications or statements to customers or government agencies regarding misconduct or potential misconduct could subject us to, among other things, fines and penalties, cancellation of contracts, loss of government granted eligibility and suspension or debarment from contracting with affected customers (including government agencies), any of which could adversely affect our business, financial condition and results of operations.

Cost overruns, inflation, delays and other risks could significantly impact our results, particularly with respect to fixed-price contracts.

It is important for us to accurately estimate and control our contract costs, particularly with respect to our fixed-price contracts, so that we can maintain positive operating margins and profitability. Our services are primarily provided on a fixed-price basis.

In recent years, our clients have increased the use of fixed-priced contracts. Under fixed-price contracts, we receive a fixed-price irrespective of the actual costs we incur and, consequently, we are exposed to a number of risks. We realize a profit on fixed-price contracts only if we can control our costs and prevent cost overruns on our contracts. Fixed-price contracts require cost and scheduling estimates that are based on a number of assumptions, including those about future

Table of Conten t s

economic conditions, our overhead costs, the utilization and availability of labor, equipment and materials and other exigencies. We could experience cost overruns if these estimates are originally inaccurate as a result of errors or ambiguities in the contract specifications or become inaccurate as a result of a change in circumstances following the submission of the estimate due to, among other things, unanticipated technical or equipment problems, difficulties in obtaining permits or approvals, changes in local laws or labor conditions, weather delays, changes in the costs of raw materials or the inability of our vendors or subcontractors to perform their obligations within budget.

If cost overruns occur, we could experience reduced profits or, in some cases, a loss for that project. If a project is significant, or if there are one or more common issues that impact multiple projects, costs overruns could increase the unpredictability of our earnings, as well as have a material adverse impact on our business, financial condition and results of operations. When cost overruns occur due to factors outside of our control, we may be able to recoup our revenues through change order; however, this process is subject to negotiations with the relevant client or customer.

Certain of our contracts require us to satisfy specific design, engineering, procurement or construction milestones in order to receive payment for the work completed or equipment or supplies procured prior to achievement of the applicable milestone. As a result, under these types of arrangements, we may incur significant costs or perform significant amounts of services prior to receipt of payment. If a client determines not to proceed with the completion of the project or if the client defaults on its payment obligations, we may face difficulties in collecting payment of amounts due to us for the costs previously incurred or for the amounts previously expended to purchase equipment or supplies.

Accounting for a contract requires judgments relative to assessing the contract’s estimated risks, revenue, costs and other technical issues. Due to the size and nature of many of our contracts, the estimation of overall risk, revenue and cost at completion is complicated and subject to many variables. Changes in underlying assumptions, circumstances or estimates may also adversely affect future period financial performance. If we are unable to accurately estimate the overall revenue or costs on a contract, then we may experience a lower profit or incur a loss on the contract.

A failure to secure new contracts may adversely affect our cash flows and financial results.

Projects we complete, except those in our Maintenance & Service service line, are generally one-time in nature with a duration of less than a year. Our financial performance depends on our ability to repeatedly win new contracts from existing and new clients. Current clients may choose other vendors for future projects. Our inability to repeatedly win new contracts from existing and new clients could have a material adverse impact on our business, financial condition and results of operations.

In addition, much of our revenue is derived from projects that are awarded through a competitive bid process. Contract bidding and negotiations are affected by a number of factors, including our own cost structure and bidding policies. The failure to bid and be awarded projects, cancellations of projects or delays in project start dates could affect our ability to deploy our assets profitably. Further, when we are awarded contracts, we face additional risks that could affect whether, or when, work will begin. We could experience a decrease in profitability if we are unable to replace canceled, completed or expired contracts with new work.

If we fail to complete a project in a timely manner, miss a required performance standard or otherwise fail to adequately perform on a project, then we may incur a loss on that project, which may reduce or eliminate our overall profitability or subject us to liquidated or other damages.

Our engagements may involve large-scale, complex projects. The quality of our performance on such projects depends in large part upon our ability to manage the relationship with our clients and our ability to effectively manage the project and deploy appropriate resources, including third-party contractors and our own personnel, in a timely manner. We may commit to a client that we will complete a project by a scheduled date. We may also commit that a project, when completed, will achieve specified performance standards. If the project is not completed by the scheduled date or fails to meet required performance standards, we may either incur significant additional costs or be held responsible for the costs incurred by the client to rectify damages due to late completion or failure to achieve the required performance standards. The uncertainty of the timing of a project can present difficulties in planning the amount of personnel needed for the project. If the project is delayed or canceled, we may bear the cost of underutilizing our non-union employees that were dedicated to fulfilling the project. In addition, performance of projects can be affected by a number of factors beyond our control, including, among other things, unavoidable delays from government inaction, power, water or other resource availability, public opposition or negative press, inability to obtain financing, weather conditions, unavailability of materials or required services, unavailability of technical or specialized labor, changes in the project scope of services

Table of Conten t s

requested by our clients, workplace and industrial accidents, denial of or delay in securing required permits, environmental hazards and labor disruptions. To the extent these events occur, the total costs of the project could exceed our estimates, and we could experience reduced profits or, in some cases, incur a loss on a project, which may reduce or eliminate our overall profitability. Further, any defects or errors, or failures to meet our clients’ expectations, could result in claims for damages against us. Failure to meet performance standards or complete performance on a timely basis could also adversely affect our reputation and client base. Any such circumstances could have a material adverse impact on our business, financial condition and results of operations.

The fact that we outsource various elements of the services we sell and use materials and equipment produced by third parties in our projects subjects us to the business risks of our subcontractors and suppliers, which could have a material adverse impact on our operations.

We depend on contractors, subcontractors and equipment and material providers to conduct our business. There is a risk that we may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by the subcontractor, customer concerns about the subcontractor or our failure to extend existing task orders or issue new task orders under a subcontract. Also, to the extent that we cannot acquire equipment and materials at reasonable costs, we experience delays in the receipt of equipment and materials, including as a result of material shortages, trade disputes, increases in levels of or goods subject to tariffs, supply chain disruptions or other factors, or if the amount we are required to pay exceeds our estimates, our ability to complete a project in a timely fashion or at a profit may be impaired. In addition, if any of our subcontractors or suppliers fail to deliver on a timely basis the agreed-upon supplies and/or perform the agreed-upon services, our ability to fulfill our obligations as a prime contractor may be jeopardized; we could be held responsible for such failures and/or we may be required to purchase the supplies or services from another source at a higher price. This may reduce the profit to be realized or result in a loss on a project for which the supplies or services are needed, which could have a material adverse impact on our business, financial condition and results of operations.

We also rely on relationships with other contractors when we act as their subcontractor or partner with them on the same project. Our future revenue and growth prospects could be adversely affected if other contractors eliminate or reduce their subcontracts or relationships with us, including due to expansion of their internal HVAC or MEP capabilities, or if a client terminates or reduces these other contractors’ programs, does not award them new contracts or refuses to pay under a contract. In addition, due to “pay when paid” provisions that are common in subcontracts, we could experience delays in receiving payment if the prime contractor experiences payment delays.

Our clients often rely on third party financing to pay for their projects, and this capital might not be available on acceptable terms or at all.

Our clients often obtain third-party financing for their projects. If our clients are unable to raise funds on acceptable terms when needed, the size of contracts we do obtain may be smaller or our clients could be required to delay the development and construction of projects, reduce the scope of those projects or take other actions that may limit the amount of work available to us. Any inability by our clients to raise the funds necessary to finance their projects could have a material adverse impact on our business, financial condition and results of operations.

We may not recognize all revenues from our backlog and awarded contracts or receive all payments anticipated under awarded projects and customer contracts.

As of December 31, 2025, we had backlog and awarded contracts of approximately $3.7 billion.

Our customers have the right under some circumstances to terminate contracts or defer the timing of our services and their payments to us. In addition, our government contracts are subject to the risks described below under “Certain contracts may give customers the right to modify, delay, curtail, renegotiate or terminate existing contracts at their convenience at any time prior to their completion, which may result in a decline in our profits and revenue.” The payment estimates for projects that have been awarded to us but for which we have not yet signed contracts have been prepared by management and are based upon a number of assumptions, including that the size and scope of the awarded contracts will not change prior to the signing of contracts, that our clients or customers will be able to obtain any necessary third-party financing for the awarded contracts and that we and our customers will reach agreement on and execute binding definitive documentation for the awarded contracts. We are not always able to enter into binding definitive documentation for an awarded contract on the terms proposed. As a result, we may not receive all of the revenues that we include in our backlog or that we estimate we will receive under awarded contracts. If we do not receive all of the revenue we currently expect to

Table of Conten t s

receive, our future operating results will be adversely affected. In addition, a delay in the receipt of revenues, even if such revenues are eventually received, may cause our operating results for a particular quarter to fall below our expectations.

In order to secure contracts for new projects, we face a variable selling cycle that requires resource commitments and has a lead time before we realize revenues.

The sales cycle for our services takes from one to twelve months. We cannot always predict the timeline for our selling cycle. Our existing and potential clients generally follow budgeting and procurement processes, and sometimes must engage in regulatory approval processes related to our services. Many of our potential clients issue a request for proposal ("RFP") for their proposed projects. For projects that we win through an RFP, we then must negotiate and execute a contract with the customer. In addition, our clients may need to obtain financing for their project.

This sales process requires the dedication of significant time by our sales and management personnel and our use of significant financial resources, with no certainty of success or recovery of our related expenses. A potential customer may go through the entire sales process and not accept our proposal. All of these factors can contribute to fluctuations in our quarterly financial performance and increase the likelihood that our operating results in a particular quarter will fall below investor expectations. These factors could also adversely affect our business, financial condition and results of operations due to increased spending by us that is not offset by increased revenues.

Certain contracts may give customers the right to modify, delay, curtail, renegotiate or terminate existing contracts at their convenience at any time prior to their completion, which may result in a decline in our profits and revenue.

Certain projects in which we participate as a contractor or subcontractor may extend for one or more years. Certain of these contracts, in particular contracts with government entities, include the right to modify, delay, curtail, renegotiate or terminate contracts and subcontracts at such customer’s convenience any time prior to their completion. Any decision by a customer to modify, delay, curtail, renegotiate or terminate our contracts at their convenience may result in a decline in our profits and revenue. If one of these customers terminates their contract for convenience, we may only be able to bill the customer (or client, as applicable) for work completed and costs incurred prior to the termination or modification, plus any commitments and settlement expenses such customer agrees to pay, but not for any work not yet performed. Such terminations may have a material adverse impact on our business, financial condition and results of operations.

From time to time, we may perform work beyond the initial scope of some of our contracts. If these clients do not approve these change orders, our results of operations could be adversely impacted.

We typically have pending change orders submitted under some of our contracts for payment of work performed beyond the initial contractual requirements for which we have already recorded revenue. In general, we cannot guarantee that such change orders will be approved in whole, in part, or at all. These change orders can be the subject of lengthy arbitration or litigation proceedings, and it is difficult to accurately predict when these change orders will be fully resolved. When these types of events occur and unresolved change orders are pending, we have used working capital in projects to cover cost overruns pending the resolution of the relevant change order. If these change orders are not approved, our revenue may be reduced in future periods, which could have a material adverse impact on our business, financial condition and results of operations.

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

Because of the nature of our contracts, at times we commit resources to projects prior to receiving payments from the client in amounts sufficient to cover expenditures on projects as they are incurred. Delays in client payments may require us to make a working capital investment. While we historically have low levels of credit loss, if a client defaults in making their payments on a project to which we have devoted resources, it could have a material adverse impact on our business, financial condition and results of operations.

If we fail to promote, maintain or enhance our brands in a cost-effective manner, we may lose market share and our revenue may decrease.

A significant portion of our revenue is earned directly or indirectly from clients in various industries. Accordingly, our brands, reputation and relationships with these customers are among our most important assets, and our ability to attract and retain customers and employees depends on brand recognition and reputation. Such dependence makes our

Table of Conten t s

business susceptible to reputational damage and to competition from other companies. A variety of events could result in damage to our reputation or brands, some of which are outside of our control, including:

• acts or omissions that adversely affect our business such as a crime, scandal, cyber-related incident, litigation or other negative publicity;

• failure to successfully perform, or negative publicity related to, a high-profile project;

• misconduct, fraud or other improper activities caused by our employees’, subcontractors’, partners’ or consultants’ failure to comply with laws or regulations;

• engagements in or perceived connections to politically or socially sensitive activities;

• infringement of our trademarks or other intellectual property by third parties or accusations that our operations infringe the intellectual property rights of third parties;

• actual or potential involvement in a catastrophic fire, explosion or similar event; or

• actual or perceived responsibility for a serious accident or injury.

Increased media coverage and interest in many of the industries that we serve, along with the intensification of media coverage generally, including through the considerable expansion in the use of social media, have increased the volume and speed at which negative publicity arising from any such events can be generated and spread, and we may be unable to timely respond to, correct any inaccuracies in, or adequately address negative perceptions arising from such media coverage. If the reputation or perceived quality of our brands declines or customers lose confidence in us, our business, financial condition and results of operations could be adversely affected.

We place significant decision-making powers with our brands’ management, which presents certain risks.

Substantially all of our business is conducted through our brands, which are separate and distinct legal entities. 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 presents certain risks, including, for example, the risk that because we lack a single enterprise resource planning system, we may be slower or less effective in our attempts to identify or react to problems affecting an important brand or that we may be slower to identify a misalignment between a brand’s and the Company’s overall business strategy. Further, if a brand fails to follow the Company’s compliance policies, we could be made party to a contract, arrangement or situation that requires the assumption of large liabilities or has less advantageous terms than is typically found in the market.

The loss of senior management or other key employees, or failure to implement effective succession planning strategies, may have a material adverse impact on our business.

We cannot assure you that we will be able to retain our existing senior management personnel or other key employees or attract additional qualified personnel. The loss of any member of our management team, particularly our brand leaders, could adversely impact our business and operations. We do not maintain, nor do we plan to obtain, “key person” life insurance policies on any of our employees. As a result, we are not insured against any losses resulting from the death of our key employees. We may modify our management structure from time to time or reduce our overall workforce, which may create marketing, operational and other business risks. In addition, if we are unable to retain other key personnel, the roles and responsibilities of those employees will need to be filled, which may require that we devote time and resources to identify, hire and integrate new employees, or be assigned to existing employees, which may require them to devote time and attention to additional responsibilities. The loss of members of our management team or other key employees and failure to implement effective succession plans could adversely affect our business, financial condition and results of operations.

Competition for our employees is intense, and we may not be able to attract, integrate or retain the appropriate number of qualified employees needed to support our business.

We are a professional and technical services company, and our business is accordingly labor intensive. Therefore, our ability to attract, retain and expand our senior management and our professional and technical staff is an important factor in determining our future success. The market for engineers, consultants and skilled labor is competitive and, from time to time, it may be difficult to attract and retain qualified individuals with the required expertise within the time frames demanded by our clients. Our failure to attract and retain key individuals could impair our ability to provide services to our clients and conduct our business effectively.

Table of Conten t s

We may also face labor shortages, particularly in our Engineering & Consulting segment, which may lead to higher wages for our existing employees and higher costs to purchase the services of third parties. Increases in labor costs, wage inflation and/or increased overtime as a result of such shortages reduce our profitability and that of our customers. Such increases in labor costs for a prolonged period of time could have a material adverse impact on our business, financial condition and results of operations.

We are subject to work stoppages, union negotiations, labor disputes and other matters associated with our labor force, which may adversely impact our operations and cause us to incur incremental costs.

As of December 31, 2025, approximately 64.1% of our full-time employees were covered by collective bargaining agreements, which on occasion may require renegotiation. The outcome of future negotiations relating to union representation or collective bargaining agreements may not be favorable to us in that they may increase our operating expenses and lower our net income as a result of higher wages or benefit expenses. In addition, negotiations with unions diverts management’s attention and could disrupt operations, which may adversely affect our results of operations. If we are unable to negotiate acceptable collective bargaining agreements, we may have to address the threat of union-initiated work actions, including work slowdowns and strikes. Depending on the nature of the threat, the impacted brand(s), the location of the affected employees or the type and duration of any work action, these actions could have a material adverse impact on our business, financial condition and results of operations.

We may be required to contribute additional cash to meet our benefit obligations associated with multiemployer pension plans in which we participate.

A multiemployer pension plan is typically established under a collective bargaining agreement with a union to cover the union-represented workers of various unrelated companies. Certain of our collective bargaining agreements with unions require us to contribute to various multiemployer pension plans; however, we do not control or manage these plans, as the plans are sponsored and administered by a board of trustees. For the year ended December 31, 2025, we contributed approximately $75.6 million to multiemployer pension plans. Under the Employee Retirement Income Security Act of 1974, as amended, an employer who contributes to a multiemployer pension plan and the members of such employer’s controlled group, absent an applicable exemption, may be jointly and severally liable for the contributing employer’s proportionate share of the plan’s unfunded vested benefits in the event the employer ceases to have an obligation to contribute to the plan or substantially reduces its contributions to the plan (i.e., in the event of a complete or partial withdrawal from an applicable multiemployer plan or plan termination). If we withdraw from a multiemployer plan or such plan is terminated, absent an applicable exemption (such as that for qualifying employers in some plans in the building and construction industry), we could be required to contribute cash (typically over a number of years) to fund our portion of the multiemployer plan’s unfunded vested benefits, which could have a material adverse impact on our business, financial condition and results of operations; however, because we do not control the multiemployer plans and the plans’ funded status changes year to year, we are unable to estimate any potential contributions that could be required if a withdrawal for which an exception does not apply were to occur.

Our profitability could suffer if we are not able to maintain adequate utilization of our workforce.

The cost of providing our services, including the extent to which we utilize our workforce, affects our profitability. The rate at which we utilize our workforce is affected by a number of factors, including our ability to transition employees from completed projects to new assignments and to hire and assimilate new employees; our ability to forecast demand for our services and thereby maintain an appropriate headcount in each of our geographies and operating units; negotiations with the unions to which our employees may belong; and our ability to manage attrition.

If we under-utilize our workforce, our profit margin and profitability could suffer, which could in turn have a material adverse impact on our business, financial condition and results of operations.

Our clients have been and could be impacted by the availability and prices of commodities, services, equipment and materials.

The availability and pricing of commodities, services, equipment and materials can affect our clients in a number of ways. For example, for those clients that produce commodity products, fluctuations in price and availability can have a direct effect on their profitability and cash flow and, therefore, their willingness to continue to invest or make new capital investments. Further, declines in commodity prices can negatively impact our business in regions whose economies are substantially dependent on commodity prices by reducing our clients’ ability to invest in capital projects. In addition,

Table of Conten t s

particularly with respect to our data center clients, the unavailability of water or other utility services may delay project completions or cause our clients to defer investments. To the extent commodity, services, equipment and materials prices and availability decline or fluctuate and our clients defer new investments or cancel or delay existing projects, the demand for our services decreases, which could have a material adverse impact on our business, financial condition and results of operations.

The availability and pricing of commodities, equipment and materials can also affect the costs of projects. Rising commodity, equipment and materials prices can negatively impact the potential returns on investments that are planned, as well as those in progress, and result in clients deferring new investments or canceling or delaying existing projects. Cancellations and delays have affected our past results and may continue to do so in significant and unpredictable ways and could have a material adverse impact on our business, financial condition and results of operations.

The loss of one or a few clients could have an adverse impact on us.

Although we provide services to a diverse portfolio of client end markets and have long-standing relationships with many of our significant clients, our clients may unilaterally reduce, fail to renew or terminate their contracts with us at any time. While no single client accounted for more than 10% of our revenue during the years ended December 31, 2025, 2024 or 2023, the loss of business from a significant client, or a number of significant clients, could have a material adverse impact on our business, financial condition and results of operations.

The nature of our business exposes us to potential liability for warranty, engineering and other related claims and our insurance policies may not provide adequate coverage.

We typically provide contractual warranties for our services and materials, guaranteeing the work performed against, among other things, defects in workmanship, and we may agree to indemnify our customers for losses related to our services. While our standard warranty period lasts twelve months, the length of these warranty periods varies, and certain projects can have longer warranty periods and include facility performance warranties that are broader than the warranties we generally provide. Warranties generally require us to re-perform the services and/or repair or replace the warranted item and any other facilities impacted thereby, at our sole expense, and we could also be responsible for other damages if we are not able to adequately satisfy our warranty obligations. In addition, we can be required under contractual arrangements with our customers to warrant any defects or failures in materials we provide. While we generally require materials suppliers to provide us warranties that are consistent with those we provide to customers, if any of these suppliers default on their warranty obligations to us, we may incur costs to repair or replace the defective materials.

Furthermore, our business involves professional judgments regarding the planning, design, development, construction, operations and management of MEP and HVAC systems. Because our projects are often technically complex, our failure to make judgments and recommendations in accordance with applicable professional standards, including engineering standards, could result in damages. An accident or other adverse event at a project site or completed project resulting from the services we performed could result in professional or product liability, personal injury (including claims for loss of life) or property damage claims or other claims against us, as well as reputational harm. Although we have adopted a range of insurance, risk management and risk avoidance programs designed to reduce potential liabilities, we may be deemed to be responsible for these professional judgments, recommendations or opinions if they are later determined to be inaccurate, or if an accident or other adverse event or failure occurs at one of our project sites or completed projects. These liabilities could exceed our insurance limits or impact our ability to obtain third-party insurance in the future, and customers, subcontractors or suppliers who have agreed to indemnify us against any such liabilities or losses might refuse or be unable to pay us. We could also be liable to third parties, including through class actions, even if we are not contractually bound to those third parties. These liabilities could exceed our insurance limits or the fees we generate, may not be covered by insurance at all due to various exclusions in our coverage and could impact our ability to obtain insurance in the future. Further, any such incident may lead to reputational harm. Any unfavorable legal ruling against us could result in substantial monetary damages, disqualification to perform services in the future or even criminal violations. As a result, warranty, engineering and other related claims could have a material adverse impact on our business, financial condition and results of operations.

Additionally, certain of our brands manufacture products sold to customers and other third parties, and we can be exposed to product liability and warranty claims if our products result in, or are alleged to result in, bodily injury and/or property damage or our products actually or allegedly fail to perform as expected. Furthermore, certain of our products are designed to support critical infrastructure and any failure of such products could result in significant product liability and warranty claims, as well as damage to our reputation in the marketplace. Our product development, manufacturing and

Table of Conten t s

testing may be inadequate to detect all defects, errors, failures and quality issues, which could impact customer satisfaction or result in claims against us. As a result, we may have, and from time to time have had, to replace certain components and/or provide remediation in response to the discovery of defects in our products, and the occurrence of any defect, error, failure or quality issue could result in cancellation of orders, product returns, damage to our reputation, diversion of our resources, lawsuits or claims by our customers or other third parties and other losses to us or to any of our customers or third parties, which could have a material adverse impact on our business, financial condition and results of operations.

Unavailability or cancellation of third-party insurance coverage would increase our overall risk exposure as well as disrupt the management of our business operations.

Our services involve significant risks of professional and other liabilities, which may substantially exceed the fees that we derive from our services. We maintain insurance coverage from third-party insurers as part of our overall risk management strategy and because some of our contracts require us to maintain specific insurance coverage limits. From time to time, we assume liabilities as a result of indemnification provisions contained in our service contracts. We cannot predict the magnitude of these potential liabilities.

We are liable to pay such liabilities from our assets if and when the aggregate settlement or judgment amount exceeds our insurance policy limits. Further, our insurance may not protect us against liability because our policies typically have various exceptions to the claims covered and also require us to assume some costs of the claim even though a portion of the claim may be covered. A partially or completely uninsured claim, if successful and of significant magnitude, could have a material adverse impact on our liquidity.

If any of our third-party insurers fail, suddenly cancel our coverage or otherwise are unable to provide us with adequate insurance coverage, then our overall risk exposure and our operational expenses would increase, and the management of our business operations would be disrupted. In addition, if we expand into new markets, we may not be able to obtain insurance coverage for these new activities or, if insurance is obtained, the dollar amount of any liabilities incurred could exceed our insurance coverage. There can be no assurance that any of our existing insurance coverage will be renewable upon the expiration of the coverage period or that future coverage will be affordable at the required limits. Any uninsured claim, either in whole or in part, as well as any claim covered by insurance but subject to a policy limit, high deductible and/or retention, if successful and of material magnitude, could have a material adverse impact on our business, financial condition and results of operations.

Cybersecurity incidents, including cyberattacks, breaches of digital security, information technology system failures and network disruptions, may result in information theft, data corruption, operational disruption and/or financial loss and cause potential liability or reputational damage or otherwise adversely affect our business.

Many of our business and operational processes are heavily dependent on traditional and emerging technology systems, some of which are managed by us and some of which are managed by third-party service and equipment providers, to conduct day-to-day operations, improve safety and efficiency and lower costs. We also collect and retain information about our customers, stockholders, vendors, employees, contractors, business partners and other parties, all of which expect that we will adequately protect such information. We use computerized systems to help run our financial and operations functions, including processing payment transactions, communicating with our employees and business partners, storing confidential records and conducting operations, which may subject our business to increased risks. This risk may be particularly heightened by our lack of a centralized enterprise resource planning system. If any of our financial, operational or other technology systems fail or have other significant shortcomings, our financial results could be adversely affected. Our financial results could also be adversely affected if an employee or other third party causes our operational systems to fail, either by error or by deliberately tampering with or manipulating our operational systems. Malicious third parties or insiders may also attempt to fraudulently induce employees or customers into disclosing sensitive information such as usernames, passwords or other information or otherwise compromise the security of our information systems. Additionally, our brands maintain some of their own information systems, data and service providers. While our cybersecurity risk management program and processes, including policies, controls and procedures, are designed to cover our brands, these measures may not be fully implemented, complied with or effective in protecting all information systems and operations.

Cybersecurity incidents are evolving and are increasing in frequency and magnitude across all business types. We have experienced, and may continue to experience, cybersecurity threats. We have implemented security measures, internal controls and testing, systems redundancy and third-party products and services that are designed to detect and protect against cyberattacks. We regularly update and review our testing protocols; however, no security measure is infallible, and

Table of Conten t s

further, we may not be able to timely deploy and monitor effective measures and protocols at our brands. Despite these measures and any additional measures we may implement or adopt in the future, our facilities and systems, and those of our third-party service providers, have been and continue to be vulnerable to cyber incidents, such as security breaches, computer viruses, other malicious or destructive software, ransomware, denial-of-service attacks, lost or misplaced data, programming errors, scams, hacking, burglary, human errors, misdirected wire transfers, damage by individuals (which may include our and our third party providers’ employees), groups or nation states or state-sponsored threats and other adverse events, including threats to our critical operations technologies. Moreover, we may acquire companies with cybersecurity vulnerabilities and/or unsophisticated security measures, which exposes us to significant cybersecurity, operational and financial risks until they are fully integrated into our information systems. Additionally, the increased use of remote working arrangements by employees, vendors and other third parties has increased the exposure to possible attacks, thereby increasing the risk of a data security compromise. Third-party systems on which we rely could also suffer such cybersecurity incidents or operational system failures. Any of these occurrences could result in material harm to our business, including disruption of our business plans; ransom payments; significant remediation and cybersecurity protection costs; loss of customer, stockholder, vendor or employee data; loss, disclosure or misappropriation of intellectual property, proprietary information or other confidential, sensitive or personal information; litigation and legal risks, including regulatory actions; potential liability; damage to our reputation or customer relationships; or damage to the Company’s competitiveness, stock price and long-term shareholder value, or otherwise have a material adverse impact on our business, financial condition and results of operations. An attack could also cause service disruptions to our internal systems or, in extreme circumstances, infiltration into, damage to or loss of control of our customers’ systems. While we maintain insurance coverage for these types of cybersecurity incidents, such insurance policies may not completely provide coverage for, or completely offset, the costs associated with such incidents, including losses from reputational harm or the costs to improve security against future similar threats. Additionally, because the techniques used to obtain unauthorized access or sabotage information technology systems change frequently and are generally not identifiable until they are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. As a result, we may be required to expend significant resources to protect against the threat of system disruptions and security breaches or to alleviate problems caused by these disruptions and breaches.

In addition, new or evolving laws and regulations governing data privacy and the unauthorized disclosure of confidential or protected information and recent legislation in certain U.S. states, including the California Consumer Privacy Act, as amended by the California Privacy Rights Act, state biometric laws and other emerging U.S. state privacy laws, pose increasingly complex compliance challenges and could potentially elevate our compliance costs. Any failure to comply with these laws and regulations, or an exposure or exfiltration of information covered by such laws and regulations, including, without limitation, in connection with a cybersecurity incident, could result in significant penalties and legal liability and could have a material adverse effect on our business, financial condition and results of operations.

We use artificial intelligence, machine learning, data science and analytics and related tools in our business, and challenges with properly managing such technologies, as well as uncertainty regarding the legal and regulatory landscape surrounding their use, could result in reputational harm, competitive harm and legal liability, and adversely affect our business.

We utilize artificial intelligence, machine learning, data science and analytics and related tools (collectively, "AI") to collect, aggregate and analyze data. We may continue to incorporate AI and related solutions into our business and services. However, there are significant risks involved in utilizing AI and no assurance can be provided that our use will enhance our business or operations or result in our business or operations being more efficient or profitable. For example, AI algorithms may be flawed, insufficient, of poor quality, reflect unwanted forms of bias or contain other errors or inadequacies, any of which may not be easily detectable. AI has also been known to produce false or “hallucinatory” inferences or outputs. Additionally, our competitors or other third parties may incorporate AI into their product and service offerings more quickly or more successfully than us, which could impair our ability to compete effectively. If the AI solutions that we create or use are deficient, inaccurate, controversial or not sufficiently competitive, we could incur operational inefficiencies, competitive harm, legal liability, brand or reputational harm or other adverse impacts on our business, operating results and financial conditions.

In addition, regulation of AI is rapidly evolving as legislators and regulators are increasingly focused on these powerful emerging technologies. The technologies underlying AI and its uses are subject to a variety of laws, including intellectual property, privacy, data protection and cybersecurity, consumer protection, competition and equal opportunity laws, and are expected to be subject to increased regulation and new laws or new applications of existing laws. We may not be able to anticipate how to respond to these rapidly evolving frameworks, and we may need to expend resources to adjust our offerings in certain jurisdictions if the legal frameworks are inconsistent across jurisdictions. Furthermore, because AI

Table of Conten t s

technology itself is highly complex and rapidly developing, it is not possible to predict all of the legal, operational or technological risks that may arise relating to the use of AI.

Legal proceedings, investigations and disputes could result in substantial monetary penalties and damages, especially if such penalties and damages exceed or are excluded from existing insurance coverage.

We engage in services that can result in substantial injury or damages that may expose us to legal proceedings, investigations and disputes. For example, in the ordinary course of our business, we may be involved in legal disputes regarding, among other things, personal injury claims, including those related to workplace accidents, property damage claims, environmental matters, employee or labor disputes, professional liability claims and general commercial disputes involving project cost overruns and liquidated damages as well as other claims. In addition, in the ordinary course of our business, we frequently make professional judgments and recommendations about engineering conditions of project sites for our clients, and we may be deemed to be responsible for these judgments and recommendations if they are later determined to be inaccurate. Any unfavorable legal ruling against us could result in substantial monetary damages or even criminal violations. We maintain insurance coverage as part of our overall legal and risk management strategy to minimize our potential liabilities; however, insurance coverage contains exclusions, caps and other limitations that may not cover our potential liabilities. Generally, our insurance program covers workers’ compensation and employer’s liability, general liability, automobile liability, professional errors and omissions liability, property and contractor’s pollution liability (in addition to other policies for specific projects). Our insurance program includes deductibles or self-insured retentions for each covered claim that may increase over time. In addition, our insurance policies contain exclusions that insurance providers may use to deny or restrict coverage. Employment practices liability and professional and pollution liability insurance policies provide for coverage on a “claims-made” basis, covering only claims actually made and reported during the policy period currently in effect. If we sustain legal liabilities that exceed or that are excluded from our insurance coverage, or for which we are not insured, it could have a material adverse impact on our business, financial condition and results of operations.

If our goodwill or other intangible assets become impaired, then our profits may be significantly reduced.

Because we have historically acquired a significant number of companies, goodwill and other intangible assets represent a majority of our assets. As of December 31, 2025, our goodwill was approximately $764.3 million and intangible assets, net was approximately $551.4 million. We are required to perform a goodwill impairment test for potential impairment at least on an annual basis. We also assess the recoverability of the unamortized balance of our intangible assets when indications of impairment are present based on expected future profitability and undiscounted expected cash flows and their contribution to our overall operations. The goodwill impairment test requires us to determine the fair value of our reporting units, which are the components one level below our reportable segments. In determining fair value, we make significant judgments and estimates, including assumptions about our strategic plans with regard to our operations. We also analyze current economic indicators and market valuations to help determine fair value. In the fiscal year 2025, we recognized (i) a goodwill impairment of $25.0 million relating to the determination that the carrying amount of one of our reporting units exceeded its fair value and (ii) a long-lived asset impairment of $2.4 million relating to the determination that the carrying amount of one of our asset groups exceed its fair value. In the fiscal year 2024, we recognized a goodwill impairment of $17.8 million relating to the determination that the carrying amount of one of our reporting units exceeded its fair value. In the fiscal year 2023, we recognized a goodwill impairment charge of $5.1 million relating to our determination that the carrying amount of one of our reporting units exceeded its fair value. To the extent economic conditions that would impact the future operations of our brands change, our goodwill may be deemed to be impaired, and we would be required to record a noncash charge that could have a material adverse impact on our business, financial condition and results of operations.

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

We primarily measure the progress toward complete satisfaction of performance obligation(s), and therefore a material portion of our revenue is recognized, using the cost-to-cost input method of accounting, which results in our 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 on amounts invoiced or claims for increased costs incurred by us due to delays and other factors. Contract losses are recognized in the fiscal period when the loss is determined. Contract profit estimates are

Table of Conten t s

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 input 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 eliminating all or a portion of any profits from other contracts that would have otherwise been reported in such period or even resulting in a loss being reported for such period. On a historical basis, we believe that we have 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 vary from estimates previously made, which may result in reductions or reversals of previously recorded revenue and profits. Any such reductions or reversals could have a material adverse impact on our business, financial condition and results of operations.

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 Securities and Exchange Commission (the "SEC") and various other governing bodies. A change in U.S. generally accepted accounting principles ("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 business, financial condition and results of operations.

We have identified material weaknesses in our internal control over financial reporting which could, if not timely remediated, adversely affect our ability to accurately and timely report our financial results.

We are required to comply with the rules of the SEC implementing Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX”), and our management will be required to certify financial and other information in our periodic reports and provide an annual management report on the effectiveness of internal control over financial reporting, starting with our Annual Report on Form 10-K for the year ending December 31, 2026. Our independent registered public accounting firm will also be required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404.

As discussed in more detail in Part II, Item 9A, "Controls and Procedures" below, we and our independent registered public accounting firm have identified material weaknesses in our internal control over financial reporting. 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 our financial statements will not be prevented or detected on a timely basis. Specifically, we did not (i) design and implement effective general information technology controls (“GITCs”) for multiple business units’ information systems that are relevant to the preparation of the consolidated financial statements or (ii) fully maintain certain components of the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") framework, including elements of information and communication and control activities.

These material weaknesses remained unremediated as of December 31, 2025. While we are developing and implementing remediation activities and will continue to dedicate significant efforts and resources to ensure our reporting requirements are met, we cannot assure you that the measures that we have taken, and that will be taken, to remediate these material weaknesses will remedy the material weaknesses or will be sufficient to prevent future material weaknesses from occurring. We also cannot assure you that we have identified all of our existing material weaknesses.

If we are unable to remediate our existing material weaknesses or identify and remediate additional material weaknesses and are unable to comply with the requirements of Section 404 of SOX or, in the future, attest that our internal control over financial reporting is effective, our business processes controls that are dependent on these ineffective controls, or that rely on data produced from these systems, could be adversely affected, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our Class A Common Stock could be negatively affected. In such cases, we also could become subject to investigations by the Nasdaq Stock Market LLC (the "Nasdaq"), the SEC or other regulatory authorities, which could require additional financial and management resources.

Risks Related to Growth and Acquisitions

As a growing company with a relatively limited operating history at our current scale, we face various risks, uncertainties, expenses and difficulties. Our business is dependent on our ability to effectively continue to develop, maintain and scale our platform.

Our expected future growth presents numerous managerial, administrative, operational and other challenges. Our ability to manage the growth of our platform will require us to continue to develop and improve our management

Table of Conten t s

information systems and our other internal systems and controls. In addition, our growth will increase our need to attract, develop, motivate and retain both our management and professional employees. The inability to effectively manage our growth or the inability of our employees to achieve anticipated performance could have a material adverse impact on our business, financial condition and results of operations.

We may not be able to achieve expected returns from our growth strategy.

We invest our capital in areas that we believe best align with our business strategy and optimize future returns. Investments in capital expenditures may not generate expected returns or cash flows. Significant judgment is required to determine which capital investments will result in optimal returns, and we could invest in strategies that are ultimately less profitable than those that we do not select. Delays in strategy implementation and the ramping of new business lines or services, or failure to optimize our investment choices, could significantly impact our ability to realize expected returns on our capital expenditures.

In addition, our growth strategy involves several risks including the following:

• unavailability of necessary funding, which may include external sources;

• inability to attract, retain and motivate key talent;

• inability to identify or acquire attractive acquisition targets;

• delays, disruptions and potential restrictions related to environmental, health and safety laws, regulations or permits;

• potential restrictions on expanding in certain geographies;

• insufficient customer demand to utilize our increased capacity;

• inability to complete construction as scheduled and within budget;

• inability to meet capital expenditure requirements for our growth strategy, including during periods of relatively low free cash flow generation, resulting from challenging industry conditions;

• increases to our cost structure until new business lines or services are ramped to adequate scale;

• potential changes in laws or provisions of government incentives and grants; and

• potential changes in government agency funding priorities with respect to relevant programs.

From time to time, we have experienced the impacts from the above items and, because these risks are a characteristic of our business, we expect to experience them in the future. The nature and extent of the impact from these risks could result in delays in our growth initiatives and the completion of our projects and increased costs.

Any of the above factors could have a material adverse impact on our business, financial condition and results of operations.

If we cannot maintain our corporate culture as we grow, we could lose the innovation, collaboration and focus that contribute to our business.

We believe that our culture has been and will continue to be a critical contributor to our success. We expect to continue to hire aggressively as we expand, and we believe our corporate culture has been crucial in our success and our ability to attract highly skilled personnel. If we do not continue to develop our corporate culture or maintain and preserve our core values as we grow and evolve, we may be unable to foster the innovation, curiosity, creativity, focus on execution, teamwork and the facilitation of critical knowledge transfer and knowledge sharing we believe we need to support our growth. Our anticipated headcount growth and our transition from a private company to a public company may result in a change to our corporate culture, which could have a material adverse impact on our business, financial condition and results of operations.

From time to time, we may evaluate and potentially consummate acquisitions or other strategic business combinations, which could require significant management attention, disrupt our business and adversely affect our financial results.

As part of our growth strategy, we acquire companies that expand, complement, and/or diversify our businesses. However, there is no guarantee that we will be successful in identifying targets that meet our requirements for acquisition.

Table of Conten t s

We may also face increased competition from other potential acquirers who may have greater financial resources available to them or who may be in a position to offer more favorable terms to the target company. This competition may limit our ability to pursue acquisition opportunities. Additionally, circumstances beyond our control, such as interest rates, inflation and potential disruptions resulting from public health emergencies, may hinder our ability to pursue and complete acquisitions. Further, realization of the anticipated benefits of an acquisition, and avoiding or mitigating the potential risks associated with an acquisition, will depend, among other things, upon our ability to (i) effectively conduct due diligence to identify and mitigate potential problems at companies we propose to acquire, (ii) recognize incompatibilities or other obstacles to the successful integration of the acquired business with our other operations and (iii) gain greater efficiencies and scale that will translate into anticipated synergies or reduced costs in a timely manner. However, there can be no assurance that an acquisition we may make in the future will provide the benefits anticipated when entering into the transaction. Acquisitions we have completed and potential future acquisitions could expose us to operational challenges and risks, including the diversion of management’s attention from our existing businesses, the failure to retain key personnel or customers of the acquired business and the assumption of unknown liabilities of the acquired business for which there are inadequate reserves. Our ability to sustain our growth and maintain our competitive position may be affected by our ability to identify and acquire desirable businesses and successfully integrate any acquired business.

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

For the reasons set forth above, any unsuccessful acquisitions could have a material adverse impact on our business, financial condition and results of operations.

We may have difficulty integrating the operations and personnel of any acquired company.

If we fail to conduct adequate due diligence on our potential targets, we may not identify problems at target companies, or fail to recognize incompatibilities or other obstacles to successful integration. For example, as we integrate past and future acquisitions and evolve our corporate culture to incorporate new workforces, some employees may not find such integration or cultural changes appealing and seek other employment. The failure to retain such personnel or to maintain our corporate culture as a result of these acquisitions may preclude realization of the full benefits expected by us as a result of such acquisitions and harm our business, financial condition or results of operations.

We may acquire other companies, which could result in dilution to our shareholders or otherwise impact our financial position.

Acquisitions we make from time to time may cause us to (i) issue equity securities that would dilute our stockholders’ ownership percentage, (ii) use a substantial portion of our cash resources, (iii) increase our interest expense, leverage and debt service requirements (if we incur additional debt to fund an acquisition) or (iv) record goodwill and non-amortizable intangible assets that are subject to impairment testing and potential impairment charges.

For instance, in connection with the Bowers acquisition and the Metrix acquisition, the Company issued 2,551,672 and 149,331 shares of Class A Common Stock, respectively. Additionally, deferred consideration in connection with the Bowers acquisition is payable on December 31, 2026, in cash, Class A Common Stock, or a combination thereof, at the Company’s discretion. In connection with the Bowers acquisition, Legence Holdings also incurred incremental term loan borrowings of $200.0 million to partially finance the Bowers acquisition. Refer to "Part II, Item 8. Financial Statements and Supplementary Data, Note 9—Debt ."

Delaware law and our organizational documents may impede or discourage a merger, takeover or other business combination with us even if the business combination would have been in the short-term best interests of our stockholders.

We are a Delaware corporation and the anti-takeover provisions of Delaware law impose various impediments to the ability of a third party to acquire control of us, even if a change in control would be beneficial to our stockholders. In addition, our board of directors (the "Board") will have the power, without stockholder approval, to designate the terms of

Table of Conten t s

one or more series of preferred stock and issue shares of preferred stock, which could be used defensively if a takeover is threatened. These features, as well as provisions in our amended and restated certificate of incorporation and amended and restated bylaws, such as those relating to advance notice of certain stockholder proposals and nominations, could impede a merger, takeover or other business combination involving us, or discourage a potential acquirer from making a tender offer for our Common Stock, even if the business combination would have been in the best interests of our current stockholders.

In addition, certain change of control events have the effect of accelerating the payment due under our TRA, which could be substantial and accordingly serve as a disincentive to a potential acquirer. See “Risks Related to Our Class A Common Stock and Structure—In certain cases, payments under the TRA may be accelerated and/or significantly exceed the actual benefits we realize, if any, in respect of the tax attributes subject to the TRA” for more information.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware (the “Delaware Court of Chancery”) as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to bring a claim in a different judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Delaware Court of Chancery will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a duty (including any fiduciary duty) owed by any of our directors, officers, employees, agents or stockholders to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (as amended, “DGCL”), our amended and restated certificate of incorporation or our amended and restated bylaws, (iv) any action to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or our amended and restated bylaws, (v) any action asserting a claim against us or any of our directors, officers, employees, agents or stockholders that is governed by the internal affairs doctrine, (vi) any action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL, or (vii) any action as to which the DGCL confers jurisdiction on the Delaware Court of Chancery; provided that the forum selection provision in our amended and restated certificate of incorporation identifies the federal district courts of the United States as the exclusive forum for any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (the “Securities Act”) or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), unless we consent in writing to the selection of an alternative forum. Notwithstanding the above, Section 22 of the Securities Act, creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder; accordingly, we cannot be certain that a court would enforce our exclusive forum provision as it relates to complaints asserting a cause of action arising under the Securities Act. This choice of forum may limit a stockholder’s ability to bring a claim in a different judicial forum for disputes with us or our directors, officers, employees or agents. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law or the Securities Act, as applicable, for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or such persons. Alternatively, if a court were to find any of the forum selection provisions contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable, we may incur additional costs associated with having to litigate such action in other jurisdictions, which could have an adverse effect on our business, financial condition, results of operations, cash flows, and prospects and result in a diversion of the time and resources of our employees, management, and our Board.

Increases and uncertainty in our health insurance costs could adversely impact our results of operations and cash flows.

The costs of employee health insurance have been increasing in recent years due to rising health care costs, legislative changes, and general economic conditions. Additionally, we may incur additional costs as a result of the Patient Protection and Affordable Care Act (the “Affordable Care Act”) that was signed into law in March 2010. Future legislation could also have an impact on our business. The status of the Affordable Care Act, any amendment, repeal or replacement thereof, is currently uncertain. For example, in December 2019, the U.S. Court of Appeals for the Fifth Circuit struck down a central provision of the Affordable Care Act, ruling that the requirement that people have health insurance was unconstitutional, sending the case back to a federal district judge in Texas to determine which of the law’s many parts could survive without the mandate. On March 2, 2020, the U.S. Supreme Court granted certiorari to review this case, and on June 17, 2021, the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. The Affordable Care Act is expected to remain in effect in its current form; however, we continue to evaluate the effect that the Affordable Care Act

Table of Conten t s

has on our business. A material increase in the costs of employee health insurance could affect our revenue and profitability, which could have a material adverse impact on our business, financial condition and results of operations.

If we expand our operations internationally, we could be subject to new challenges and risks and our financial results could be adversely affected.

International expansion is one of our growth strategies, and we may derive a portion of our revenues and operations from outside of the United States in the future. If we expand internationally, these operations will be subject to a variety of risks that we do not face in the United States, including:

• building and managing a highly experienced foreign workforce and overseeing and ensuring the performance of foreign subcontractors;

• conforming our service offerings to various international regulatory requirements, including the European Union General Data Protection Regulation;

• complying with the U.S. FCPA, economic sanctions, export controls and other U.S. regulations associated with cross-border business activities;

• difficulties in obtaining or complying with various licenses, approvals, certifications and other authorizations necessary to provide our service offerings in any of these jurisdictions;

• difficulties attracting customers in new jurisdictions;

• increased travel, infrastructure and legal and compliance costs associated with multiple international locations;

• additional withholding taxes or other taxes on our foreign income, and tariffs or other restrictions on foreign trade or investment;

• imposition of, or unexpected adverse changes in, foreign laws or regulatory requirements, many of which differ from those in the United States;

• exposure to foreign currency exchange rate risk;

• longer payment cycles for sales in some foreign countries and potential difficulties in enforcing contracts and collecting accounts receivable;

• difficulties in repatriating overseas earnings;

• international and regional economic, political and labor conditions in the countries in which we operate; and

• political unrest, war, incidents of terrorism, pandemics or responses to such events.

Our overall success in international markets will depend, in part, on our ability to succeed in differing legal, regulatory, economic, social, and political conditions. We may not be successful in developing and implementing policies and strategies that will be effective in managing these risks in each country where we do business. Our failure to manage these risks successfully could harm our international operations, reduce our international sales, and increase our costs, thus adversely affecting our business, financial condition and operating results. Further some of our customers, vendors or suppliers may have international operations and are also subject to these risks, and if they are unable to appropriately manage these risks, our business may be harmed.

Risks Related to Indebtedness

We have a significant amount of existing indebtedness and our ability to make scheduled payments on or to refinance our obligations will depend on many factors, some of which are beyond our control.

Our ability to generate cash in order to make scheduled payments on the principal of, to pay interest on or to refinance our indebtedness depends on our future performance, which is subject to economic, financial, competitive, legislative, regulatory and other factors beyond our control, including those discussed in this section. In addition, our ability to borrow funds in the future to make payments on our debt will depend on the satisfaction of the covenants in the agreements governing our Credit Facilities and our other financing and other agreements we may enter into in the future. Specifically, we are required to maintain certain leverage ratios under certain, specified circumstances. Our business may not continue to generate sufficient cash flow from operations in the future and future borrowings may not be available to us under our Credit Facilities or from other sources in an amount sufficient to service our indebtedness to make necessary

Table of Conten t s

capital expenditures, complete acquisitions or to fund our other liquidity needs. If we are unable to generate cash from our operations or through borrowings, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to make payments on our indebtedness or refinance our indebtedness will depend on factors, including the state of the capital markets and our financial condition at such time, as well as the terms of our financing agreements. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations and have a material adverse impact on our business, financial condition and results of operations.

We may not be able to finance future needs or adapt our business plan to react to changes in economic or business conditions because of restrictions placed on us by our Credit Facilities and any other instruments governing our other indebtedness.

The agreements governing our debt contain a number of restrictive covenants which will limit our ability to finance future operations, acquisitions or capital needs or engage in other business activities that may be in our interest.

The agreements governing our debt contain a number of significant covenants that impose operating and other restrictions on us and our subsidiaries. Such restrictions affect or will affect and, in many respects, limit or prohibit, among other things, our ability and the ability of some of our subsidiaries to:

• incur additional indebtedness;

• create liens;

• pay dividends and make other distributions in respect of our equity securities;

• redeem or repurchase our equity securities;

• make investments or other restricted payments;

• sell assets;

• enter into transactions with affiliates; and

• effect mergers or consolidations.

In addition, these agreements require us to comply with certain leverage ratios under certain, specified circumstances. Our ability to comply with these ratios may be affected by events beyond our control. These restrictions could limit our ability to plan for or react to market or economic conditions or meet capital needs or otherwise restrict our activities or business plans and could adversely affect our ability to finance our operations, acquisitions, investments or strategic alliances or other capital needs or to engage in other business activities that would be in our interest. A breach of any of these covenants or our inability to comply with the required financial ratios could result in a default under our debt instruments. If an event of default occurs, our creditors could elect to:

• declare all borrowings outstanding, together with accrued and unpaid interest, to be immediately due and payable;

• require us to apply all of our available cash to repay the borrowings; or

• prevent us from making debt service payments on our borrowings.

If we were unable to repay or otherwise refinance our borrowings when due, the applicable creditors could sell the collateral securing some of our debt instruments, which constitutes substantially all of our and our subsidiaries’ assets. Such events could have a material adverse impact on our business, financial condition and results of operations.

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

Borrowings under our Credit Facilities 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 the amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. Without taking into consideration the effect of our interest rate swap agreements, based upon our outstanding principal amount of floating rate debt of $797.8 million as of December 31, 2025, and $1,590.4 million as of December 31, 2024, an increase in the current interest rate levels of 1.00% would result in an increase in our annual interest expense of $8.0 million and $15.9 million, respectively. As of December 31, 2025 and December 31, 2024,

Table of Conten t s

we had interest rate swap agreements in effect with notional amounts of $785.0 million and $815.0 million, respectively. We may, from time to time, enter into additional interest rate derivatives that involve a cap on our interest rate or the exchange of floating for fixed rate interest payments in order to reduce interest rate volatility. However, we may not maintain interest rate derivatives with respect to all of our variable rate indebtedness, and any derivatives we enter into may not fully mitigate our interest rate risk and could be subject to credit risk themselves. A material increase in our debt service obligations as a result of rising interest rates could have material adverse impact on our business, financial condition and results of operations.

Our incurrence of additional indebtedness may affect our business and may restrict our operating flexibility.

From time to time, we may seek additional debt financing to fund the capital requirements of our business or to refinance all or a portion of our existing indebtedness. There is no guarantee that we can continue to renew our Credit Facilities on terms as favorable as those in our existing Credit Facilities and, if we are unable to do so, our costs of borrowing and our business may be adversely affected. The changing nature of the global credit markets could make it more difficult for us to access funds, refinance our existing indebtedness, enter into agreements for uncommitted debt bond facilities and new indebtedness, replace our existing Credit Facilities or obtain funding through the issuance of our securities. Our inability to access credit on acceptable terms, if at all, could have a material adverse impact on our business, financial condition and results of operations.

A downgrade in our debt rating could restrict our ability to access the capital markets.

The terms of our financings are, in part, dependent on the credit ratings assigned to our debt by independent credit rating agencies. We cannot provide assurance that our current credit rating will remain in effect for any given period of time or that it will not be lowered or withdrawn entirely by a rating agency. Factors that may impact our credit rating include, among other things, our debt levels and liquidity, capital structure, financial performance, planned asset purchases or sales, near- and long-term growth opportunities, client base and market position, geographic diversity, regulatory environment, project performance and risk profile. A downgrade in our credit rating could limit our ability to access the debt capital markets or refinance our existing debt or cause us to refinance or issue debt with less favorable terms and conditions. An increase in the level of our indebtedness and related interest costs may increase our vulnerability to adverse general economic and industry conditions and may affect our ability to obtain additional financing, as well as have a material adverse impact on our business, financial condition and results of operations.

We may not be able to maintain sufficient bonding and letter of credit capacity to successfully bid on and win some contracts.

In line with industry practice, we are often required under the terms of our contracts, to provide performance and payment bonds or letters of credit to our customers. These instruments indemnify the customer should we fail to perform our obligations under the contract. If a bond or a letter of credit is required for a particular project and we are unable to obtain an appropriate bond or letter of credit, we cannot pursue that project. Historically, we have had adequate bonding and letter of credit capacity but, as is typically the case, the issuance of a bond is at the surety’s sole discretion and the issuance of a letter of credit is based on our creditworthiness. Because of an overall lack of worldwide bonding capacity, we may find it difficult to find sureties who will provide required levels of bonding, or such bonding may only be available at significant additional cost. There can be no assurance that our bonding capacity will continue to be available to us on reasonable terms. In addition, future projects may require us to obtain letters of credit that extend beyond the term of our existing Credit Facilities. Our inability to obtain adequate bonding and, as a result, to bid on new contracts that require such bonding or letter of credit could have a material adverse impact on our business, financial condition and results of operations.

We may incur liability to our clients under our ESPCs if our projects do not meet the promised performance standards and energy use reductions to which we are committed to under our contracts.

ESPCs are agreements where the scope of work is aligned with contractually established performance standards or guarantees. Should any of these guarantees not be fulfilled, we may face associated risks. Each contract varies regarding the types of guarantees and the duration for which these guarantees must be sustained.

The majority of our ESPCs guarantee a specific reduction in energy consumption and or usage. If the scope of work fails to achieve these reductions, we may be required to compensate the client for the shortfall and/or make additional investments to meet the guaranteed savings. ESPCs can also provide for a certain decrease in operational or maintenance

Table of Conten t s

costs. New equipment typically incurs lower maintenance expenses. However, in case of equipment failures, maintenance issues, or comfort concerns, we may face increased costs that could adversely affect profitability. If the energy and operational parameters are not met and, more importantly, not resolved, the client may refuse to pay for the services rendered, resulting in financial losses.

Under our ESPCs, we typically do not take responsibility for a wide variety of factors outside our control and exclude or adjust for such factors in our guarantee as well as our post-project measurements and the resulting calculations. These factors include variations in energy prices and utility rates, weather, facility occupancy schedules, the amount of energy-using equipment in a facility, changes in occupancy type, certain industrial or production process loads, future building renovations or projects and failure of the client to operate or maintain the project properly. If the project does not perform, the reconciliation of these variables and their effect on the performance can be disputed, presenting certain legal and financial risks. Further, variations in energy prices can alter a client’s baseline energy usage, potentially limiting savings from efficiency measures, reducing project scope, or affecting the client’s perceived savings achieved through energy efficiency measures, each of which may lead to legal disputes or financial challenges and impact our reputation and ability to secure future projects.

We rely in part on warranties from our equipment suppliers and subcontractors to back-stop the warranties we provide to our customers under ESPCs and, where appropriate, pass on the warranties to our customers. However, the warranties we provide to our customers are sometimes broader in scope or longer in duration than the corresponding warranties we receive from our suppliers and subcontractors, and we may bear the risk for any differences, as well as the risk of warranty default by our suppliers and subcontractors.

ESPCs are long-term contractual agreements that may carry a heightened risks of liabilities or expenses in the future, which we may not be able to predict. Such liabilities or expenses could be substantial, and they could materially harm our business, financial condition and results of operations.

Despite our current indebtedness levels, we and our subsidiaries may still be able to incur substantially more debt. This could further exacerbate the risks associated with our leverage.

Under the terms of the Credit Agreement, Legence Holdings and its subsidiaries may be able to incur substantial additional indebtedness in the future. Subject to certain conditions, Legence Holdings may incur additional indebtedness in the form of term loans or revolving loans in an aggregate principal amount equal to the sum of (x) the greater of $68.0 million and 100% of the company’s most recently reported last-twelve-month EBITDA (calculated in accordance with the Credit Agreement), (y) the aggregate amount of certain voluntary prepayments and permanent commitment reductions of other indebtedness of Legence Holdings and its subsidiaries and (z) additional unlimited amounts, subject to compliance with the following leverage ratios: (i) for debt secured on a pari passu basis with the obligations under the Credit Agreement, a first lien net leverage ratio no greater than 5.25x, (ii) for debt secured on a junior-priority basis to the obligations under the Credit Agreement, a secured net leverage ratio no greater than 6.25x and (iii) for unsecured debt or debt that is not secured by any collateral that secures the obligations under the Credit Agreement, either (x) a total net leverage ratio no greater than 6.75x or (y) an interest coverage ratio no less than 2.00x. Solely in the case of incremental term loans or revolving loans incurred to finance a permitted acquisition or permitted investment, Legence Holdings and its subsidiaries may incur unlimited indebtedness so long as, after giving effect to such acquisition or investment, the first lien net leverage ratio, secured net leverage ratio or total net leverage ratio, as applicable, is no greater than the level immediately prior to such incurrence or the interest coverage ratio is not less than the level immediately prior to such incurrence, as applicable. The incurrence of such additional indebtedness is subject to other customary conditions including, but not limited to, the absence of an event of default and certain maturity limitations.

With respect to the incurrence tests described above, as of December 31, 2025, we estimate that Legence Holdings and its subsidiaries would have been able to incur (i) approximately $1.4 billion of debt secured on a junior-priority basis to the obligations under the Credit Agreement and (ii) approximately $1.5 billion of unsecured debt or debt that is not secured by any collateral that secures the obligations under the Credit Agreement. Legence Holdings and its subsidiaries could also have incurred unlimited indebtedness in connection with a permitted acquisition or investment to the extent such transaction was leverage-neutral.

In addition, the debt covenant under the Credit Agreement provides for additional exceptions that could permit an unlimited amount of debt under certain circumstances, including in connection with non-speculative hedging agreements, certain acquisitions, indemnification obligations, purchase price adjustments, insurance premiums and certain other debt incurred in the ordinary course of business or consistent with Legence Holdings’ past practice. If new indebtedness is

added to Legence Holdings and its subsidiaries’ current debt levels, the related risks that we and they now face could intensify. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt.”

Risks Related to Regulations

Our business and our clients’ businesses are subject to a variety of federal, state and local laws and regulations, which could adversely affect our business, financial condition and results of operations.

Federal, state and local laws and regulations affecting our clients, including, among other things, environmental, health and safety, and permitting requirements, may have a material effect on our business. These regulations are complex and subject to change both in substance and interpretation, and often regulations across various industries and jurisdictions can differ or conflict, all of which can negatively impact our or our clients’ ability to efficiently operate. Furthermore, certain regulatory requirements applicable to our clients are also required of us when we contract with such clients, and our inability to meet those requirements could also result in decreased demand for our services. Increased and changing regulatory requirements applicable to us and our clients have resulted in, among other things, project delays for our services in the past, and may do so in the future, which can adversely affect our business, financial condition and results of operations. Changes in law, regulations or requirements, or a material failure to comply with any of them, could increase our costs and have other negative impacts on our business by, among other things, increasing costs, harming our reputation and, in some instances, causing us to be in violation of our contractual obligations.

Additionally, we collect and retain information about our customers, stockholders, vendors and employees. Legislation and regulatory requirements, as well as contractual commitments, affect how we must store, use, handle, transmit, transfer and otherwise process the confidential and personal information of our customers, stockholders, vendors and employees. These laws, as well as other new or changing legislative, regulatory or contractual requirements concerning data privacy and protection, could require us to expend significant additional compliance costs, and any failure to comply with such requirements can result in significant liability or harm to our reputation.

If we are found to not have complied with applicable laws, we could lose one or more of our licenses, permits or authorizations or face other sanctions or penalties or be required to obtain additional licenses or permits, which may limit our business operations in particular jurisdictions or otherwise harm our business.

We are subject to federal, state and local laws and regulations that affect our business, including laws relating to data privacy and security, employment and labor relations, environmental, health and safety protection, construction and building maintenance, immigration, taxation, anti-corruption, anti-bribery, import-export controls, trade restrictions, internal and disclosure control obligations, securities regulation, anti-competition and state and local licensing regulations. Although we have policies and procedures directed at complying with such laws, the violation of such laws could subject us and our employees to civil or criminal penalties, including substantial monetary fines, or other adverse actions, including debarment from participation in U.S. government contracts, and could damage our reputation and our ability to do business.

In addition, we and many of our clients operate in highly regulated environments, which requires us or our clients to obtain, maintain and to comply with, federal, state and local government permits and approvals. These permits or approvals are subject to denial, revocation or modification under various circumstances. Failure to obtain, maintain or comply with, or the loss or modification of, the conditions of permits or approvals subjects us to the risk of penalties, cessation of our operations or other liabilities or risks which could have a material adverse impact on our business, financial condition and result of operations.

Finally, we regularly issue reports and opinions to clients based on our professional engineering expertise, as well as our other professional credentials. Our reports and opinions may need to comply with professional standards, licensing requirements and other laws and rules governing the performance of professional services in the jurisdiction in which the services are performed. While we aim to include disclaimers in the reports and opinions that we prepare for our clients, once we produce such written work product, we do not always have the ability to control the manner in which our clients use such information. If such reports or opinions prove to be incorrect, or our clients misuse such information, our professional licenses in the relevant jurisdiction may be reviewed or revoked, and we may be subject to lawsuits by our clients.

Some of our clients receive federal, state and local government incentives for building new facilities or to make energy efficiency upgrades to their buildings. If these incentives are reduced or limited, the scope for some of our projects may be impacted and there may be less demand for our services.

Some of our clients receive federal, state and local government incentives for building new facilities or to make energy efficiency upgrades to their buildings. For example, they may benefit from federal legislation, including the Inflation Reduction Act of 2022, the Infrastructure Investment and Jobs Act, the CHIPS Act of 2022 and state and local legislation provided for tax credits, grants, subsidies and rebates to businesses, as well as federal, state and local governmental bodies, for investments in new facilities or for making energy efficiency upgrades to their facilities. Additionally, certain jurisdictions have adopted building performance standards that require commercial and multifamily buildings to meet certain energy efficiency levels.

Any reductions or modifications to, or the elimination of, these governmental incentives, policies, programs or laws that support building new facilities or energy efficiency upgrades, or that require certain energy efficiency levels, could impact the scope of our projects with some clients. Further, if energy prices decline in the future, the return on investment some clients expect to realize from some projects may be reduced, making upgrades offered by our services less financially compelling for those clients, and therefore reducing demand for our services. Finally, the Supreme Court’s recent decision in Loper Bright Enterprises v. Raimondo , which restricted federal agencies’ ability to interpret vague or broad legislation, could introduce uncertainty around applicable agency regulations and, therefore, negatively impact the demand for our services.

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 tax returns with the Internal Revenue Service (the “IRS”) and in 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 for which the most appropriate tax treatment is unsettled or unresolved. 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. On July 4, 2025, the One Big Beautiful Bill Act (“the Act”) was enacted into law. The Act includes significant changes to the U.S. tax code, including restoration of immediate recognition of domestic research and development expenditures and reinstatement of 100% bonus depreciation for qualifying property. The Act also removes the deductions under Code Section 179D for energy-efficient commercial buildings, effective for properties where construction begins after June 30, 2026. Additionally, the Act eases the limitation on interest expense deductions by allowing companies to calculate their income for Code Section 163(j) purposes before deducting depreciation and amortization. The Company incorporated the estimated effects of the Act within its financial statements for the three and twelve months ended December 31, 2025, which did not have a material impact on its effective tax rate. While the Company's current estimates do not result in a material impact, the ultimate effect will depend on a number of factors, including the issuance of regulatory guidance and further interpretation of the Act. The Company will continue to monitor developments and evaluate the impact of the Act on its consolidated financial statements, including the effects on its deferred tax assets and liabilities, and will recognize any required adjustments in the period in which the analysis is complete and the impacts can be quantified with reasonable certainty.

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 business, financial condition and results of operations. Further, the results of tax examinations and audits could have a negative impact on our results of operations and financial condition where the results differ from the liabilities recorded in our financial statements. Finally, we will not be reimbursed for any cash payments previously made to the TRA Members under the TRA in the event that any tax benefits initially claimed by us and for which payment has been made to the TRA Members are subsequently challenged by a taxing authority and are ultimately disallowed.

Changes in U.S. trade policy, including the imposition of tariffs and the resulting consequences, may have a material adverse impact on our business, financial condition and results of operations.

During the year ended December 31, 2025, the U.S. government announced significant trade policy and tariff actions on imports from a broad set of countries. These tariffs and other changes in U.S. trade policy have triggered and

Table of Conten t s

could continue to trigger retaliatory actions by affected countries, and certain foreign governments have instituted or are considering imposing retaliatory measures on certain U.S. exports or bans on certain of their exports. As a result, there may be greater restrictions and economic disincentives on international trade. More recently, on February 20, 2026, the U.S. Supreme Court ruled that certain trade tariffs imposed by the U.S. federal government under the International Emergency Economic Powers Act ("IEEPA") were unconstitutional. Following the U.S. Supreme Court’s decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. Significant uncertainty remains regarding the status of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended. Additionally, international conflicts like Russia’s invasion of Ukraine in February 2022 and the ongoing conflict involving Iran, may also give rise to trade sanctions, which have impacted and could impact in the future the operations and financial performance for companies worldwide.

We, our suppliers and our customers import certain raw materials, components and other products from foreign suppliers, including, but not limited to, the steel and aluminum used by our fabrication facilities. As such, while the duration, extent and effects of the above mentioned tariffs and trade actions cannot be predicted with certainty, they have in the past and may continue to adversely impact demand for our services, our costs, our customers, our suppliers and the U.S. economy, which in turn could have an adverse impact on our business, financial condition and results of operations.

We are government contractors, and our brands are accordingly subject to a number of rules and regulations, and their contracts with government entities are subject to audit. Violations of the applicable rules and regulations could result in a brand being barred from future government contracts.

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 suspension or debarment from bidding on or being awarded government contracts in the future. Further, a violation by one of our brands could impact our other brands’ ability to bid on and perform government contracts. Prohibitions against bidding on future government contracts could have a material adverse impact on our business, financial condition and results of operations.

Further, our books and records and those of our brands are subject to audit by the various public sector clients we serve and their representatives. These audits can result in adjustments to the amount of contract costs we believe are reimbursable by the agencies and the amount of our overhead costs allocated to the agencies. If such matters are not resolved in our favor, they could have a material adverse impact on our business. Furthermore, as a government contractor, we are subject to an increased risk of investigations, criminal prosecution, civil fraud actions, whistleblower lawsuits and other legal actions and liabilities to which purely private sector companies are not, the results of which could materially adversely impact our business. For example, from time to time we may be subject to qui tam lawsuits, a type of claim which typically alleges false statements or certifications in connection with claims for payment, or improperly retained overpayments, from the government. These suits may remain under seal (and hence, be unknown to us) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff.

Risks Related to the Environment, Health and Safety

Environmental, health and safety laws could impose significant additional costs and liabilities.

We are subject to a variety of environmental, health and safety laws and regulations governing, among other things, discharges to air and water, the handling, storage and disposal of hazardous or waste materials, including ozone-depleting refrigerants such as chlorofluorocarbons or hydrochlorofluorocarbons, the remediation of contamination associated with the releases of hazardous substances, and human health and safety. For example, federal environmental, health and safety laws which affect us include, but are not limited to, the Clean Water Act, the Clean Air Act, the Safe Drinking Water Act, the Resource Conservation and Recovery Act, the National Environmental Policy Act, the Occupational Safety and Health Act and the Toxic Substances Control Act, as well as other comparable federal and state laws. Compliance with these laws and regulations and the risk of litigation can cause, among other things, significant delays to a project and add significantly to its cost.

Various U.S. federal, state and local environmental laws and regulations, such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, and comparable state laws, may impose liability for property damage and costs of investigation and cleanup of hazardous or toxic substances at properties currently or previously owned, leased or operated by us or third-party sites to which we sent, transported or arranged to send wastes.

Table of Conten t s

These laws may impose responsibility and liability without regard to our knowledge of or causation of the presence of contaminants. The liability under these laws may be joint and several. We currently own, lease and operate, and have formerly owned, leased and operated, facilities where industrial activities have occurred or occurs, and such industrial activities have resulted, and may in the future result, in contamination at some of these properties. We have been in the past involved in remediation activities at some of our current and former facilities and may be required to conduct remediation activities in the future. In addition, our waste management activities may result in liabilities. The discovery of contamination or the imposition of unforeseen or new clean-up obligations at any of our current or former sites or other sites (including third-party sites) could have a material adverse impact on our business, financial condition and results of operations.

Environmental, health and safety laws and regulations and policies are reviewed periodically, and any changes thereto could affect us in substantial and unpredictable ways. Such changes could, for example, relax or repeal laws and regulations relating to energy efficiency or the environment, which could result in a decline in the demand for our services and, in turn, could negatively impact our revenue. See “Risk Factors—Risks Related to Regulations—Some of our clients receive federal, state and local government incentives for building new facilities or to make energy efficiency upgrades to their buildings. If these incentives are reduced or limited, the scope for some of our projects may be impacted and there may be less demand for our services.” Furthermore, changes in environmental, health and safety laws and regulations, remediation obligations, enforcement actions, stricter interpretations of existing requirements, discovery of contamination or claims for damages to persons, property, natural resources or the environment could result in material costs and liabilities that we currently do not anticipate. Failure to comply with any environmental, health or safety laws or regulations, whether actual or alleged, exposes us to, among other things, fines, penalties, damages, liabilities, cessation of our operations or potential litigation risks, including costs, settlements and judgments, any of which could adversely affect our business, financial condition and results of operations.

We are exposed to risks relating to occupational, health and safety matters and operate at project sites that involve a high degree of operational hazards and risks. Failure by us or any of our business partners to maintain safe work sites and equipment could have a material adverse impact on our business, financial condition and results of operations.

Our operations are subject to extensive laws and regulations relating to the maintenance of safe conditions in the workplace, including those promulgated by the Occupational Safety and Health Administration (“OSHA”), which have and may continue to become more stringent over time. While we have invested, and will continue to invest resources in our occupational, health, and safety programs, many of our businesses involve a high degree of operational hazards and risks, and there can be no assurance that we will avoid significant exposure to such hazards and risks. For example, the project sites at which we operate, including construction sites and industrial facilities, often put our employees and others in close proximity with mechanized equipment, moving vehicles, chemical and manufacturing processes and highly regulated or hazardous materials. These sites and conditions can create numerous safety risks, including but not limited to fall risks, electrocutions, fires, explosions, mechanical failures, transportation accidents and damage to equipment. While our general contractors are generally responsible for overseeing the project sites, on some project sites, we are responsible for occupational safety and accordingly have an obligation to implement effective safety procedures. In addition, we could have liability for any damages arising as a result of our general contractor’s failure to oversee occupational safety. These hazards and risks and any failure to implement effective safety procedures can cause, among other things, personal injury and loss of life, severe damage to or destruction of property and equipment and other consequential damages, and could lead to fines or penalties, suspension or cessation of operations, claims, costs to remediate occupational hazards, an increase in employee turnover, civil litigation and criminal liability. Any of the foregoing could have a material adverse impact on our business, financial condition and results of operations.

Furthermore, poor safety performance could also jeopardize our relationships with our customers, negatively impact employee morale and harm our reputation. Our customers seek to minimize safety risks on their sites, and they frequently review the safety records of contractors during the bidding process. Accordingly, if our safety record were to substantially deteriorate over time, we might become ineligible to bid on certain work and our customers could cancel our contracts and/or not award us future business. As a result, failure to maintain adequate safety standards, training and equipment by us or any of our subcontractors could result in reduced profitability or the loss of projects or clients, and have a material adverse impact on our business, financial condition and results of operations.

Table of Conten t s

Increasing scrutiny, regulatory requirements and changing expectations from various stakeholders with respect to sustainability and other environmental, social and governance matters may impose additional costs on us or expose us to reputational or other risks.

Investors, customers and other stakeholders have focused increasingly on sustainability and ESG practices of companies, including, among other things, practices with respect to human capital resources, emissions, climate change and environmental impact. Stakeholder expectations are not uniform and support for and opposition to ESG-related matters have increasingly resulted in a range of activism and legal and regulatory developments. Expectations and requirements of our investors, customers and other third parties evolve rapidly, whether in support of or opposition to ESG-related matters, and are largely out of our control, and our initiatives and disclosures in response to such expectations and requirements may result in increased costs (including but not limited to increased costs related to compliance, stakeholder engagement, contracting and insurance), changes in demand for certain services, enhanced compliance or disclosure obligations or other adverse impacts to our business, financial condition and results of operations. While we have programs and initiatives in place related to our sustainability practices, there is no assurance that our stakeholders will agree with our sustainability-related strategies, and investors may decide to reallocate capital or to not commit capital as a result of their assessment of our services and practices. In addition, our customers, business partners and suppliers may be subject to similar expectations and may require that we implement certain additional procedures or standards to continue to do business with us, which may augment or create additional costs or risks, including costs or risks that may not be known to us. Any failure to comply with investor, customer and other stakeholder expectations and standards, which are evolving and can conflict, or if we are perceived (whether validly or not) not to have responded effectively to their growing concerns around sustainability or ESG issues, regardless of whether there is a legal requirement to do so, or to effectively respond to new or additional legal or regulatory requirements regarding climate change, sustainability or ESG matters or potential regulatory/investor engagement or litigation, could also cause or result in reputational harm to our business and could have a material adverse impact on our business, financial condition and results of operations. In addition, organizations that provide ratings information to investors on sustainability or ESG matters may assign unfavorable ratings to us, our clients or our industries. These ratings may lead to negative investor sentiment and the diversion of investment to other companies or industries, which could have a negative impact on our service offerings, stock price and costs of capital.

Additionally, various governmental authorities have adopted or proposed, and are likely to continue to adopt or propose, legislative and regulatory initiatives regarding the management of sustainability- and ESG-related topics, or disclosures on such topics, particularly with respect to climate change. For example, in October 2023, California enacted various pieces of legislation (certain of which are currently subject to ongoing legal challenges) that will ultimately require companies that do business in California and meet certain financial thresholds to publicly disclose their Scopes 1, 2, and 3 greenhouse gas (“GHG”) emissions with third-party assurance of such data and issue public reports on their climate-related financial risk and related mitigation measures and require companies that operate in California and make certain climate-related claims to provide substantiation for such claims, including those regarding net zero, carbon neutrality and significant emissions reductions, and information on the use of voluntary carbon offsets. Separately, various regulators have adopted, or are considering adopting, regulations on environmental marketing claims or the prevention of greenwashing more generally, including, but not limited to the use of “sustainable,” “eco-friendly,” “green” or similar language in the marketing of products and services or the prevention of greenwashing more generally. Additionally, the Federal Trade Commission (“FTC”) has published guidance, the FTC “Green Guides,” to assist advertisers in avoiding the dissemination of false or deceptive environmental claims for their products and provide guidance regarding the use of “renewable energy”, or “carbon offsets” and other environmental benefit claims.

Moreover, while we create and publish voluntary disclosures regarding sustainability matters from time to time, many of the statements in those voluntary disclosures are based on hypothetical expectations and estimates and assumptions that may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many sustainability matters. Further, there has been increasing scrutiny on sustainability-related claims, including increased frequency of allegations of “greenwashing” against companies making sustainability-related claims due to, among other things, allegations of incomplete, false or misleading disclosures, including with respect to the sustainable nature of their operations and products, as well as to a variety of perceived deficiencies in performance, including as stakeholder perceptions of sustainability continue to evolve. Our failure, or perceived failure, to manage reputational risks, meet expectations with respect to sustainability-related commitments and initiatives, substantiate and verify the veracity of our sustainability-related claims or effectively respond to new or increased regulations, laws or demands related to sustainability matters, could negatively impact our brand credibility, stakeholder relationships, willingness of our customers and suppliers to do business with us, business, financial condition and results of operations.

Table of Conten t s

Any of the foregoing may also expose us to increased greenwashing claims, litigation or enforcement actions; require us to incur additional costs for the collection of data and/or preparation of disclosures and associated internal controls for the same; or impact the availability and cost of key raw materials used in our services or the demand for our services, which, in turn, may adversely impact our business, results of operations and financial condition.

We may be unable to achieve our current or future climate commitments and other goals, or we may incur substantial costs in meeting such commitments and goals.

We have established a GHG emissions reduction goal and other sustainability commitments. Achievement of such commitments and goals, or similar commitments and goals that may be established in the future, is subject to risks and uncertainties, many of which are outside of our control. These risks and uncertainties include, but are not limited to: (i) our ability to execute our operational strategies and achieve our goals within the currently projected costs and the expected timeframes; (ii) the availability and cost of alternative fuels, electrical vehicles, electrical charging infrastructure, off-site renewable energy and other materials and components; (iii) unforeseen design, operational, and technological difficulties; (iv) the outcome of research efforts and future technology developments; (v) regulations and requirements that restrict or prohibit our ability to impose requirements on third-party contractors; (vi) reductions, modification to or elimination of governmental incentives or policies that support renewable energy, electric vehicles or charging infrastructure; (vii) an acquisition of or merger with another company that has not adopted similar commitments and goals or whose progress towards reaching its commitments or goals is not as advanced as ours; and (viii) exogenous macroeconomic or supply chain shocks, such as those experienced during the COVID-19 pandemic, which could result in fluctuations in our fuel consumption and GHG emissions in a given period. In addition, we could be required to expend amounts in future periods as we continue to work towards achieving our commitments and goals, which may have a material effect on our business, financial condition and results of operations.

Our business is subject to the risks of earthquakes, fire, power outages, floods and other catastrophic events, and to interruption by man-made problems such as political disruption, strikes and terrorism.

Force majeure or extraordinary events beyond the control of the contracting parties, such as natural and man-made disasters, as well as outbreaks of infectious disease (e.g., COVID-19), acts of sabotage, terrorist actions and geopolitical tensions, including the conflict in Iran, could negatively impact us. We typically negotiate contract language intended to grant us certain relief from force majeure events in private client contracts and review and attempt to mitigate force majeure events in both public and private client contracts. We remain obligated to perform our services after most extraordinary events subject to relief that may be available to us pursuant to a force majeure clause, or in the event that relief from force majeure events is not provided or is denied. If we are not able to react quickly to force majeure events, our operations may be affected significantly, which would have a material adverse impact on our business, financial condition and results of operations and could also negatively affect our reputation in the marketplace.

Climate change and related environmental issues could have an adverse impact on our business, in part because our headquarters and some of our project sites are located in active earthquake zones or in areas susceptible to physical risks of climate change, including wildfires and other severe weather events. An earthquake, wildfire or other man-made or natural disaster or resource shortage, including public safety power shut-offs that have occurred and will continue to occur in California or other states, could disrupt and harm our operations.

Our headquarters and various project sites are located in California, an active earthquake zone. In addition, the effects of climate change may increase both the frequency and severity of extreme weather conditions and natural disasters, which may affect our business operations. The occurrence of extreme weather conditions or a man-made or natural disaster, including as a result of climate change, such as an earthquake, drought, hurricanes, freezing conditions, extreme heat, flood, hail, fire (such as the extensive wildfires that occur in California), localized extended outages of critical utilities (such as California’s public safety power shut-offs), water scarcity, damage to infrastructures, impacts to transportation systems or any critical resource shortages could cause a significant interruption in our or our customers’ business, damage or destroy our or our customers’ facilities or inventory or cause us to incur significant costs, any of which could harm our business, financial condition and results of operations. The activities of our third-party vendors and other suppliers, manufacturers, business partners and distributors may be similarly disrupted. Any insurance we maintain against such risks may not be adequate to cover losses in any particular case, and such insurance may become increasingly expensive or unavailable.

Risks Related to Our Class A Common Stock and Structure

Our sole material asset consists of our membership interests in Legence Holdings (held by us directly and indirectly), and we are accordingly dependent upon distributions from Legence Holdings to pay taxes, make payments under the TRA and cover our corporate and other overhead expenses.

We have no material assets other than our membership interests in Legence Holdings (held directly by us and indirectly through certain wholly owned subsidiaries of the Company, through which the Company indirectly owns ownership interests in Legence Holdings (collectively, the "Pubco Subsidiaries")). We have no independent means of generating revenue or cash flow, and our ability to pay our taxes and operating expenses (including payments due under the TRA) or declare and pay dividends in the future, if any, is dependent upon the financial results and cash flows of Legence Holdings and distributions we receive from Legence Holdings. Legence Holdings is treated as a partnership for U.S. federal tax purposes and, as such, generally is not subject to any entity-level U.S. federal income tax. Instead, any taxable income of Legence Holdings is allocated to holders of LGN Units, including us and the Pubco Subsidiaries. Accordingly, we will incur income taxes on our allocable share of any net taxable income of Legence Holdings. Legence, the Pubco Subsidiaries and Legence Parent ML, as the members of Legence Holdings, hold the LGN Units, and their interests therein and rights as members are governed by the Legence Holdings LLC Agreement and the Exchange Agreement. Under the terms of the Legence Holdings LLC Agreement, Legence Holdings is obligated, subject to various limitations and restrictions, including with respect to our debt agreements, to make tax distributions to holders of LGN Units, including us and the Pubco Subsidiaries. To the extent Legence Holdings has available cash, we intend to cause Legence Holdings (i) to generally make pro rata distributions to its unitholders, including us and the Pubco Subsidiaries, and then cause the Pubco Subsidiaries to subsequently make distributions to us, in an amount at least sufficient to allow us to pay our taxes and make payments under the TRA and (ii) to reimburse us for our corporate and other overhead expenses through non-pro rata payments that are not treated as distributions under the Legence Holdings LLC Agreement. To the extent that we are unable to make payments under the TRA for any reason, such payments will be deferred and will accrue interest until paid. We may be limited, however, in our ability to cause Legence Holdings and its subsidiaries to make these and other distributions to us due to the restrictions under our existing Credit Facilities. To the extent that we need funds and Legence Holdings or its subsidiaries are restricted from making such distributions under applicable law or regulation or under the terms of their financing arrangements, or are otherwise unable to provide such funds, it could have a material adverse impact on our business, financial condition and results of operations.

We do not intend to pay dividends and may never pay dividends.

The Board may elect to declare cash dividends on our Class A Common Stock, subject to our compliance with applicable law. The declaration and amount of any future dividends is subject to the discretion of the Board, and we have no obligation to pay any dividends at any time. We do not intend to pay dividends and may never pay dividends. We have not adopted, and do not currently expect to adopt, a written dividend policy. Our future dividend policy will be based on the operating results and capital needs of our business, and any future earnings may be retained to finance our future expansion and for the implementation of our business plan.

The payment of dividends is dependent on, among other things, economic conditions, our financial condition, results of operations, projections, liquidity, earnings, legal requirements and restrictions in the agreements governing our indebtedness. Our ability to pay dividends depends on our receipt of cash dividends from our operating subsidiaries, which may further restrict our ability to pay dividends as a result of the laws of their jurisdiction of organization, agreements of our subsidiaries or covenants under any existing and future outstanding indebtedness we or our subsidiaries incur.

Further, our Credit Facilities contain restrictions on the payment of dividends, subject to certain exceptions. Any financing arrangements or debt arrangements that we enter into in the future may also include restrictive covenants that limit our ability to pay dividends.

As an investor, you should take note of the fact that a lack of a dividend may affect the market value of our Class A Common Stock and could affect the value of any investment.

Our sale or issuance of additional Common Stock or other equity-related securities could dilute each stockholder’s ownership interest or adversely affect the market price of our Class A Common Stock.

We often fund a significant portion of the consideration paid in connection with our acquisitions with the issuance of additional equity securities, including contingent consideration amounts payable if acquired businesses achieve certain performance objectives during specified post-acquisition periods. We also utilize stock-based compensation as a key

Table of Conten t s

component of our compensation program. We expect to issue additional equity securities in the future in connection with these and other practices. Our amended and restated certificate of incorporation provides that we may issue up to 1,000,000,000 shares of Class A Common Stock, of which 67,338,099 shares were outstanding as of March 24, 2026. Any additional issuances of common stock would have the effect of diluting our earnings per share and our existing stockholders’ individual ownership percentages and lead to volatility in the market price of our Class A Common Stock. We cannot predict the effect that future issuances of our Common Stock or other equity-related securities would have on the market price of our Class A Common Stock.

In accordance with Delaware law and the provisions of our amended and restated certificate of incorporation, we may issue one or more classes or series of preferred stock that ranks senior in right of dividends, liquidation or voting to our Common Stock. Preferred stock may have such designations, preferences, limitations and relative rights, including preferences over our Common Stock respecting dividends and distributions, as our Board may determine, and the issuance of preferred stock would dilute the ownership of our existing stockholders. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our Class A Common Stock.

We will be required to make payments under the TRA for certain tax benefits we may claim, and the amounts of such payments could be significant.

We have entered into a TRA with the TRA Members. This agreement generally provides for the payment by us to the TRA Members of 85% of the net cash savings, if any, in U.S. federal, state and local income tax that we (a) actually realize with respect to taxable periods ending after the IPO or (b) are deemed to realize in the event the TRA terminates early at our election, as a result of our breach or upon a change of control (as defined under the TRA, which includes certain mergers, asset sales and other forms of business combinations and certain changes to the composition of the Board) with respect to any taxable periods ending on or after such early termination event, in each case, as a result of (i) our allocable share of existing tax basis acquired in connection with our IPO and increases to such allocable share of existing tax basis; (ii) our utilization of certain tax attributes of the Blocker Entities; (iii) increases in tax basis resulting from future redemptions or exchanges (or deemed exchanges in certain circumstances) of Legence Holdings interests for Class A Common Stock or cash and certain distributions (or deemed distributions) by Legence Holdings pursuant to the Exchange Agreement (any resulting tax basis increases, the "Basis Adjustments"); and (iv) certain additional tax benefits arising from payments made under the TRA. If the TRA terminates early, we could be required to make a substantial, immediate lump-sum payment. “Certain Relationships and Related Party Transactions, and Director Independence—Tax Receivable Agreement” contains more information.

The payment obligations under the TRA are our obligations and not obligations of Legence Holdings. For purposes of the TRA, cash savings in tax generally are calculated by comparing our actual tax liability to the amount we would have been required to pay had we not been able to utilize any of the tax benefits subject to the TRA. The amounts payable, as well as the timing of any payments, under the TRA are dependent upon future events and assumptions, including the timing of the exchanges of LGN Units along with surrendering a corresponding number of our Class B Common Stock, the price of our Class A Common Stock at the time of each exchange, the extent to which such exchanges are taxable transactions, the amount of the exchanging LGN Unit Holder’s tax basis in its LGN Units at the time of the relevant exchange, the depreciation, depletion and amortization periods that apply to the increase in tax basis, the amount and timing of taxable income we generate in the future, the U.S. federal, state and local income tax rates then applicable and the portion of Legence’s payments under the TRA that constitute imputed interest or give rise to depreciable, depletable or amortizable tax basis. We expect that the payments that we will be required to make under the TRA could be substantial. Any payments made by us to the TRA Members under the TRA will not be available for reinvestment in Legence Holdings (or indirectly, its business) and generally will reduce the amount of overall cash flow that might have otherwise been available to us. The term of the TRA will continue until all such tax benefits have been utilized or expired and all required payments are made, unless we exercise our right to terminate the TRA (or the TRA is terminated due to other circumstances, including our breach of a material obligation thereunder or certain mergers or other changes of control) by making the termination payment specified in the agreement. In the event that the TRA is not terminated, the payments under the TRA are anticipated to commence in late 2026 or early 2027 (with respect to the 2025 tax year).

The payments under the TRA will not be conditioned upon a holder of rights under the TRA having a continued ownership interest in us or Legence Holdings. In addition, certain rights under the TRA (including the right to receive payments) will be transferable in connection with transfers permitted thereunder. “Certain Relationships and Related Party Transactions, and Director Independence—Tax Receivable Agreement” contains more information.

Table of Conten t s

In certain cases, payments under the TRA may be accelerated and/or significantly exceed the actual benefits we realize, if any, in respect of the tax attributes subject to the TRA.

If the TRA terminates early at our election, as a result of our breach or upon a change of control (as defined under the TRA, which includes certain mergers, asset sales and other forms of business combinations and certain changes to the composition of the Board), we could be required to make a substantial, immediate lump-sum payment. This payment would equal the present value of hypothetical future payments that could be required under the TRA. The calculation of the hypothetical future payments will be based upon certain assumptions and deemed events set forth in the TRA, including (i) the sufficiency of taxable income to fully utilize the tax benefits, (ii) U.S. federal, state and local tax rates for future periods, (iii) treating any LGN Units (other than those held by us (including through the Pubco Subsidiaries)) outstanding on the termination date as exchanged on the termination date, (iv) the taxable disposition of certain non-amortizable property and (v) the utilization of certain loss carryovers. Such lump-sum payment to the TRA Members could be greater than the specified percentage of any actual benefits we ultimately realize in respect of the tax benefits that are subject to the TRA. In these situations, our obligations under the TRA could have a substantial negative impact on our liquidity.

Our ability to generate net taxable income is subject to substantial uncertainty. Accordingly, as a result of the assumptions, the required lump-sum payment may be significantly in advance of, and could materially exceed, the realized future tax benefits to which the payment relates. This payment obligation could (i) make us a less attractive target for an acquisition, particularly in the case of an acquirer that cannot use some or all of the tax benefits that are the subject of the TRA and (ii) result in holders of our Class A Common Stock receiving substantially less consideration in connection with a change of control transaction than they would receive in the absence of such obligation. Accordingly, the TRA Members’ interests may conflict with those of the holders of our Class A Common Stock.

If the TRA terminates early at our election, as a result of our breach or upon a change of control (as defined under the TRA, which includes certain mergers, asset sales and other forms of business combinations and certain changes to the composition of the Board), we could be required to make payments under the TRA that exceed our actual cash tax savings under the TRA. Consequently, our obligations under the TRA could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control. There can be no assurance that we will be able to finance our obligations under the TRA. We may need to cause Legence Holdings to incur debt and make distributions to the holders of LGN Units, including us and the Pubco Subsidiaries, to finance payments under the TRA to the extent our cash resources are insufficient to meet our obligations under the TRA as a result of timing discrepancies or otherwise. “Certain Relationships and Related Party Transactions, and Director Independence—Tax Receivable Agreement” contains more information.

We will not be reimbursed for any payments made under the TRA in the event that any tax benefits are subsequently disallowed.

Payments under the TRA will be based on the tax reporting positions that we will determine, which are complex and factual in nature, and the IRS or another tax authority may challenge all or part of the tax basis increases upon which payments under the TRA are based, as well as other related tax positions that we take, and a court could sustain such challenge. The holders of rights under the TRA will not reimburse us for any payments previously made under the TRA if such basis increases or other benefits are subsequently disallowed, except that excess payments made to any such holder will be netted against payments otherwise to be made, if any, to such holder after our determination of such excess. However, we might not determine that we have effectively made an excess cash payment to a TRA Member for a number of years following the initial time of such payment and, if any of our tax reporting positions are challenged by a taxing authority, we will not be permitted to reduce any future cash payments under the TRA until any such challenge is finally settled or determined. As a result, in such circumstances, we could make payments that are greater than our actual cash tax savings, if any, and may not be able to recoup those payments, which could adversely affect our liquidity. The applicable U.S. federal income tax rules for determining applicable tax benefits we may claim are complex and factual in nature, and there can be no assurance that the IRS or a court will not disagree with our tax reporting positions. As a result, payments could be made under the TRA significantly in excess of any actual cash tax savings that we realize in respect of the tax attributes that are the subject of the TRA.

If Legence Holdings were to become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes, we and Legence Holdings might be subject to potentially significant tax inefficiencies, and we would not be

Table of Conten t s

able to recover payments previously made by us under the TRA even if the corresponding tax benefits were subsequently determined to have been unavailable due to such status.

We intend to operate such that Legence Holdings does not become a publicly traded partnership taxable as a corporation for U.S. federal tax purposes. A “publicly traded partnership” is a partnership the interests of which are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof. Under certain circumstances, exchanges of LGN Units pursuant to the Exchange Right (as defined below) or other transfers of LGN Units could cause Legence Holdings to be treated as a publicly traded partnership. Applicable U.S. Treasury regulations provide for certain safe harbors from treatment as a publicly traded partnership, and we intend to operate such that exchanges or other transfers of LGN Units qualify for one or more such safe harbors.

If Legence Holdings were to become a publicly traded partnership, significant tax inefficiencies might result for us and for Legence Holdings, including as a result of our inability to file a consolidated U.S. federal income tax return with Legence Holdings. In addition, we would no longer have the benefit of certain increases in tax basis covered under the TRA, and we would not be able to recover any payments made by us under the TRA, even if the corresponding tax benefits (including any claimed increase in the tax basis of Legence Holdings’ assets) were subsequently determined to be unavailable.

In certain circumstances, Legence Holdings will be required to make tax distributions to us and the Pubco Subsidiaries, and the LGN Unit Holders, and the tax distributions that Legence Holdings will be required to make may be substantial.

Legence Holdings is treated as a partnership for U.S. federal tax purposes and, as such, is not subject to U.S. federal income tax. Instead, taxable income is allocated to the LGN Unit Holders and us (including through the Pubco Subsidiaries). Pursuant to the Legence Holdings LLC Agreement, Legence Holdings will generally make pro rata cash distributions, or tax distributions, to the LGN Unit Holders and us and the Pubco Subsidiaries, in an amount at least sufficient to allow us to pay our taxes and meet our payment obligations under the TRA.

Funds used by Legence Holdings to satisfy its tax distribution obligations will not be available for reinvestment in our business. Moreover, the tax distributions that Legence Holdings will be required to make may be substantial and may exceed (as a percentage of Legence Holdings’ income) the overall effective tax rate applicable to a similarly situated corporate taxpayer.

The price of our Class A Common Stock may fluctuate significantly, and you could lose all or part of your investment.

The market price of our Class A Common Stock may be highly volatile and could be subject to wide fluctuations. Securities markets worldwide experience significant price and volume fluctuations. The following is a non-exhaustive list of factors that could affect the market price of our Class A Common Stock.

• our operating and financial performance;

• quarterly variations in the rate of growth of our financial indicators, such as net income per share, net income and revenues;

• the public reaction to our press releases, our other public announcements and our filings with the SEC;

• strategic actions by our competitors;

• our failure to meet revenue or earnings estimates by research analysts or other investors;

• changes in revenue or earnings estimates, or changes in recommendations or withdrawal of research coverage, by equity research analysts;

• speculation in the press or investment community;

• the failure of research analysts to cover our Class A Common Stock;

• sales of our Class A Common Stock by us or other stockholders, or the perception that such sales may occur;

• changes in accounting principles, policies, guidance, interpretations or standards;

• additions or departures of key management personnel;

• actions by our stockholders;

• general market conditions, including fluctuations in commodity prices;

• domestic and international economic, legal and regulatory factors unrelated to our performance; and

• the realization of any risks described under this “Risk Factors” section.

The stock markets in general have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our Class

Table of Conten t s

A Common Stock. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. Such litigation, if instituted against us, could result in substantial costs, divert our management’s attention and resources and harm our business, financial condition and results of operations.

Our Sponsor controls a significant percentage of our voting power.

As of March 24, 2026, funds (such funds, collectively, our "Sponsor") associated with Blackstone Inc. and certain management holders beneficially owned (through Legence Parent ML and Legence Parent II ML, each of which is controlled by our Sponsor) approximately 61% of our outstanding Common Stock. As such, our Sponsor has the power to control our business and affairs. In addition, certain of our directors are currently employed by our Sponsor. Consequently, our Sponsor is able to influence matters that require approval by our stockholders, including the election and removal of directors, changes to our organizational documents and approval of acquisition offers and other significant corporate transactions. This concentration of ownership will limit your ability to influence corporate matters, and as a result, actions may be taken that you may not view as beneficial. This concentration of stock ownership may also adversely affect the trading price of our Class A Common Stock to the extent investors perceive a disadvantage in owning stock of a company with a controlling stockholder.

Our Sponsor may have interests that conflict with the interests of our other stockholders. Certain of our directors may also have conflicts of interest because they are also employees of our Sponsor, investment advisors to our Sponsor managed funds or directors or officers of our Sponsor. The resolution of these conflicts of interest may not be in our or your best interests.

Our Sponsor may have interests that conflict with the interests of our other stockholders. In addition, certain of our directors may also have conflicts of interest because they are also employees of our Sponsor, investment advisors to our Sponsor managed funds or directors or officers of our Sponsor. These positions may conflict with such individuals’ duties as one of our directors or officers, regarding business dealings and other matters between our Sponsor and us. The resolution of these conflicts may not always be in our or your best interest.

A significant reduction by our Sponsor of its ownership interests in us could adversely affect us.

We believe that our Sponsor’s substantial ownership interest in us provides it with an economic incentive to assist us to be successful. As of the date of this Annual Report, our Sponsor is not subject to any obligation to maintain its ownership interest in us and may elect at any time thereafter to sell all or a substantial portion of or otherwise reduce its ownership interest in us. If our Sponsor sells all or a substantial portion of its ownership interest in us, it may have less incentive to assist in our success.

Such actions could adversely affect our ability to successfully implement our business strategies which could have a material adverse impact on our business, financial condition and results of operations.

Our Sponsor is not limited in its ability to compete with us, and the corporate opportunity provisions in our amended and restated certificate of incorporation could enable our Sponsor to benefit from corporate opportunities that may otherwise be available to us.

Our Sponsor may invest in other companies in the future that may compete with us. Conflicts of interest could arise in the future between us, on the one hand, and our Sponsor, on the other hand, concerning, among other things, potential competitive business activities or business opportunities.

Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by applicable law, we renounce any interest or expectancy in any business opportunity that involves any aspect of the energy equipment or services business or industry and that may be from time to time presented to our Sponsor or any of our directors or officers who is also an employee, partner, member, manager, officer or director of our Sponsor or any affiliate of our Sponsor, even if the opportunity is one that we might reasonably have pursued or had the ability or desire to pursue if granted the opportunity to do so. Our amended and restated certificate of incorporation further provides that no such person or party shall be liable to us by reason of the fact that such person pursues any such business opportunity or fails to offer any such business opportunity to us. As a result, any of our directors or officers who is also an employee, partner, member, manager, officer or director of our Sponsor or any affiliate of our Sponsor may become aware, from time to time, of certain business opportunities, such as acquisition opportunities, and may direct such opportunities to other businesses in which they have invested, in which case we may not become aware of or otherwise have the ability to pursue such opportunity. Further, such businesses may choose to compete with us for these opportunities. As a result, by renouncing our interest and expectancy in any business opportunity that may be from time to time presented to our Sponsor or an affiliate of our Sponsor or any of our directors or officers who is also an employee, partner, member, manager, officer or director of our Sponsor or any affiliate of our Sponsor, our business or prospects could be adversely affected if attractive business

Table of Conten t s

opportunities are procured by such parties for their own benefit rather than for ours. Any actual or perceived conflicts of interest with respect to the foregoing could have an adverse impact on the trading price of our Class A Common Stock.

We are a “controlled company” within the meaning of the rules of the Nasdaq and, as a result, qualify for, but do not currently rely on, exemptions from certain corporate governance requirements. In the event we elect to rely on these exemptions in the future, you will not have the same protections afforded to stockholders of companies that are subject to such requirements.

As of the date of this Annual Report, our Sponsor controls a majority of our voting power. As a result, we are a “controlled company” within the meaning of the Nasdaq corporate governance standards. Under the Nasdaq rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and need not comply with certain requirements, including the requirement that a majority of the board of directors consist of independent directors and the requirements that our Compensation Committee (as defined below) and Nominating and Governance Committee (as defined below) each be composed entirely of independent directors. We do not currently utilize these exemptions. However, for so long as we qualify as a “controlled company,” we will maintain the option to utilize some or all of these exemptions. If we utilize these exemptions, we may not have a majority of independent directors and our Compensation and Nominating and Governance Committees may not consist entirely of independent directors, and such committees will not be subject to annual performance evaluations. Accordingly, in the event we elect to rely on these exemptions in the future, you may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the Nasdaq. See “Item 10. Directors, Executive Officers and Corporate Governance—Status as a Controlled Company.”

Future sales of our Class A Common Stock in the public market could reduce the market price of our Class A Common Stock, and any additional capital raised by us through the sale of equity or convertible or exchangeable securities may dilute ownership in us.

We may sell additional shares of Class A Common Stock in future public offerings. We may also issue additional shares of Class A Common Stock or convertible or exchangeable securities (including LGN Units). Certain of our Existing Owners (or their designees) are party to a registration rights agreement (as described in “Certain Relationships and Related Party Transactions—Registration Rights Agreement”), which, among other things, requires us, in certain circumstances, to register shares of Class A Common Stock (including shares of Class A Common Stock into which LGN Units are redeemable).

In addition, as of March 24, 2026, an aggregate of 25,341,365 shares of Class A Common Stock, 40,699,833 shares of Class B Common Stock and 40,699,833 LGN Units, representing approximately 61% of the issued and outstanding Class A Common Stock, assuming the exchange of all outstanding LGN Units (other than those held directly or indirectly by the Company), together with a corresponding number of shares of Class B Common Stock, for shares of Class A Common Stock on a one-for-one basis, are pledged to secure obligations of Legence Parent ML and Legence Parent II ML under margin loan agreements with Goldman Sachs Bank USA, as administrative agent, and the lenders party thereto from time to time. Any foreclosure upon those shares could result in sales of a substantial number of shares of our Class A Common Stock in the public market, which could substantially decrease the market price of our Class A Common Stock. We have also registered all shares of Class A Common Stock that we may issue under our equity compensation plans, which can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates.

We cannot predict the size of future issuances of our Class A Common Stock or securities convertible into or exchangeable for Class A Common Stock or the effect, if any, that future issuances and sales of shares of our Class A Common Stock will have on the market price of our Class A Common Stock. Sales of substantial amounts of our Common Stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of our Class A Common Stock. This impact could be increased to the extent there is a less active trading market for our shares.

If securities or industry analysts do not publish research reports or publish unfavorable research about our business, the price and trading volume of our Class A Common Stock could decline.

The trading market for our Class A Common Stock is influenced by the research and reports that industry or securities analysts publish about us or our business. We do not control these analysts. If any of the analysts who cover us downgrade our Class A Common Stock or our industry, or publish inaccurate or unfavorable research about our business, the price of our Class A Common Stock may decline. If analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the price or trading volume of our Class A Common Stock to decline and our Class A Common Stock to be less liquid.

The requirements of being a public company, including compliance with the reporting requirements of the Exchange Act, and the requirements of SOX and the Nasdaq, may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

Table of Conten t s

As a public company, we need to comply with laws, regulations and requirements, certain corporate governance provisions of SOX, related regulations of the SEC and the requirements of the Nasdaq, with which private companies are not required to comply. Complying with these statutes, regulations and requirements will occupy a significant amount of time of our Board and management and will significantly increase our costs and expenses.

In addition, as a public company subject to these rules and regulations, it may be more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our Board or as executive officers. We are currently evaluating these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and related notes that appear elsewhere in this filing. In addition to historical consolidated financial information, the following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and expected performance. The forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, the risks and uncertainties described under “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors” and elsewhere in this filing. Our actual results may differ materially from those contained in or implied by any forward-looking statements. We do not undertake any obligation to publicly update any forward-looking statements except as otherwise required by applicable law.

Overview

We are a leading provider of engineering, installation and maintenance services for mission-critical systems in buildings. We focus on high-growth sectors that have technically demanding buildings, including technology, life sciences, healthcare and education.

Our business is growing rapidly as data centers, manufacturers, pharmaceutical companies, hospitals, schools and universities make investments in both new and existing facilities to support growing demand for their products and services, reduce energy costs and increase resiliency. In 2025, we generated more than half of our revenues from “high growth industries,” which we define as clients operating in the data center & technology and life sciences & health care end-markets. As of December 31, 2025, we had $3.7 billion of backlog and awarded contracts, representing an increase of 49% over the same date last year.

We specialize in designing, fabricating and installing complex HVAC, process piping and other MEP systems for new facilities and upgrading HVAC, lighting and building controls in existing facilities to enhance building performance, improve reliability and drive efficiency. In 2025, we generated approximately 40% of our revenues from new building projects and approximately 60% of our revenues from retrofits, upgrades and maintenance for existing buildings. Our team includes approximately 1,200 MEP engineers and energy consultants, and approximately 6,200 HVAC and plumbing service technicians, fitters, electricians and sheet metal workers.

Our clients include large technology and industrial companies and public sector institutions who contract with us directly to provide services, as well as intermediaries such as architects and general contractors who subcontract MEP services to us as part of a larger project. We served approximately 20,000 clients from 2019 through 2025. In 2025, we generated approximately 2% of our revenues from the federal government. Excluding maintenance contracts which can span multiple years, we typically complete most of our jobs within nine months.

Recent Developments

On November 13, 2025, the Company entered into an equity purchase agreement to acquire all of the outstanding equity of The Bowers Group, Inc. The acquisition was completed on January 2, 2026. In connection with the consummation of the Bowers acquisition, Legence Holdings obtained a $200.0 million incremental term loan, and used the proceeds to fund acquisition-related payments. The incremental term loan increased the quarterly principal payments to $2.5 million.

On March 1, 2026, the Company acquired Metrix Engineers, LLC.

On February 25, 2026, the Board adopted the 2026 Employee Stock Purchase Plan ("2026 ESPP"), including the reservation of 1,580,053 shares of Class A Common Stock for issuance under the 2026 ESPP. The 2026 ESPP is subject to the approval of our stockholders.

In March 2026, we entered into interest rate swap agreements.

These items are further described under “ Note 4—Acquisitions , ” “ Note 9—Debt ," “ Note 12—Stockholders' Equity / Member's Equity ” and “ Note 11—Derivatives ,” respectively, in Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data".

Business Segments

We operate through two segments: Engineering & Consulting and Installation & Maintenance.

Table of Conten t s

Engineering & Consulting

Our Engineering & Consulting segment designs HVAC and other MEP systems for buildings, develops strategies to help reduce energy usage and make buildings more sustainable and provides program and project management services for clients’ installation and retrofit projects. Our Engineering & Consulting segment has two principal service offerings:

• Engineering & Design . We provide planning, design and engineering services for HVAC, process piping and other MEP systems in both new and existing buildings. We also develop strategies for building owners and operators to help reduce their utility consumption and enhance building performance, improve reliability, and drive efficiency. We generated approximately 59% of our 2025 Engineering & Consulting segment revenues from selling Engineering & Design services.

• Program & Project Management . We provide comprehensive program and project management services, including facility condition and operational assessments, space utilization and capacity analyses, funding source identification and construction management. For certain clients, we provide design-build services through ESPCs for building retrofits. Under ESPC contracts, financing sources provide the funds required to pay us for the upgrades and receive a portion of the client’s energy savings to recoup their investment and generate a return. We generated approximately 41% of our 2025 Engineering & Consulting segment revenues from selling Program & Project Management services.

Installation & Maintenance

Our Installation & Maintenance segment fabricates and installs HVAC systems, process piping and other MEP systems in new and existing industrial, commercial and institutional buildings and provides ongoing preventative and corrective maintenance services for those systems. Our Installation & Maintenance segment has two principal service offerings:

• Installation & Fabrication. We provide HVAC, electrical, plumbing, process and control system installations, refurbishments and renovations in technically demanding new and existing buildings. We perform both “design-build” and “plan and specification” (“P&S”) projects. Under design-build projects, we provide the design for the project and install it. Under P&S projects, our client is responsible for designing the project and we install it to their specifications. For certain jobs, we also fabricate customized components that are not readily available for purchase from other third-party vendors or provide modular construction services based on a client’s specifications. We generated approximately 82% of our 2025 Installation & Maintenance segment revenues from Installation & Fabrication services.

• Maintenance & Service. We provide preventative maintenance, emergency repair and break-fix services over the life of a building’s mechanical systems. Our services include regular inspections and maintenance to prevent downtime; responding to calls and sending technicians onsite to repair a system failure or malfunction; and other complementary services such as facility energy analysis, automation and optimization, system certification and testing. We typically provide preventative maintenance services under annual or longer-term agreements that range from one to five years. The majority of these services are provided using a cost-plus contract type. We generated approximately 18% of our 2025 Installation & Maintenance segment revenues from Maintenance & Service work.

Key Factors Affecting Our Performance

We believe that our financial performance, results of operations and future success depend on a number of factors that present significant opportunities for us but also pose risks and challenges, including those described below and in the information contained or referenced under "Part I, Item 1A. Risk Factors."

Commercial Construction Activity

Demand for our services depends in part on commercial construction activity, which is subject to business and economic cycles. We typically see greater demand for our services when the economy is growing and interest rates are stable or falling because these conditions encourage businesses to invest in their facilities. We typically see less demand for our services when the economy is contracting and interest rates are rising. To mitigate the impact of downturns in the economy on our business, we have focused on sectors with strong secular growth that we believe are less sensitive to macroeconomic conditions, including technology, life sciences and education, and on services that help clients reduce their energy costs because we believe cost reduction is attractive to clients in all economic environments.

Table of Conten t s

Investment in Technology and Related Infrastructure

We derive a significant portion of our revenues from technology companies, and demand for our services depends, in part, on technology companies making continued investments in their facilities. Investment in technology is subject to a number of factors, including the frequency and nature of innovations, whether or not developing or implementing those innovations requires new physical infrastructure and the availability of capital to fund investments in that infrastructure.

Service Mix

The margin we earn can vary significantly based on the type of service we perform, the size of the job as well as other factors. We typically earn higher margins on engineering and design, program and project management, and maintenance services than we earn on installation and fabrication services and higher margins on smaller jobs than we earn on larger jobs. Our overall margins can vary between quarters based on service mix in the period.

Labor Costs and Productivity

Our largest expense is the wages and salaries of our employees. Our margins depend on our ability to accurately estimate the amount of labor that each job will require because our customer contracts are typically fixed-price. We have a long track record of accurately estimating our job costs.

Subcontractor and Equipment Expenses

We subcontract certain scopes of work to third parties, particularly in our Program & Project Management service line within our Engineering & Consulting segment. We record the amounts we pay to subcontractors as subcontractor expense in our cost of revenue.

We also purchase certain types of equipment that we install in our clients’ facilities, including chillers, heat pumps, packaged HVAC systems, pumps, valves and switchgear, primarily in our Installation & Fabrication service line within our Installation & Maintenance segment. We record the amounts we pay for equipment in our cost of revenue.

We may pass both subcontractor and equipment costs on directly to our customers as a specific line item or incorporate them into our overall price for the job. Variability in the amount of subcontracting that we do, subcontractor pricing, equipment purchases, including equipment that is fabricated in-house, and associated markups can impact our margins. Generally, these markups may not be as large as the markup on our labor and, therefore, the volume of subcontractor and equipment costs can also impact our margins.

The following table presents our subcontractor and equipment expenses (dollars in thousands):

For the Year Ended December 31,

Subcontractor Expense

Equipment Expense

Acquisitions

We have a pipeline of acquisition opportunities and intend to continue to pursue acquisitions as part of our strategy to increase our scale, expand existing or acquire new capabilities, access new clients, or broaden our geographic reach. While we target acquisitions that will enhance our growth and profitability, they may add redundant operating expenses in the short-term. Our ability to successfully execute strategic acquisitions depends upon a number of factors, including sustained execution of a disciplined acquisition strategy and our ability to effectively integrate acquired companies or assets into our business.

Effects of Seasonality

Our revenues are subject to seasonal fluctuations, particularly in regions with colder winter climates and areas prone to extreme weather events, such as wildfires, storms, flooding, and hurricanes. We generally see greater levels of activity in the spring and summer months than we do in the winter months due to reduced construction activity during inclement weather and less use of air conditioning during colder months. Activity in our business also fluctuates with the academic

Table of Conten t s

calendar, as most schools and colleges prefer to have work performed on their facilities when classes are not in session, which drives increased revenue from education clients during the second and third quarters of the year. Consequently, we may occasionally experience consecutive quarterly declines in revenues or earnings that are not indicative of the future performance of our business.

Supply Chain Disruptions and Other Global Factors

We continue to monitor the impact of global economic conditions on our operations, financial results and liquidity, such as the impact of tariffs, supply chain challenges and geopolitical tensions. On February 20, 2026, the U.S. Supreme Court ruled that certain trade tariffs imposed by the U.S. federal government under the IEEPA were unconstitutional. Following the U.S. Supreme Court’s decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. Significant uncertainty remains regarding the status of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended. Import duties, tariffs and other import restrictions restrict the global supply of, and raise prices for, supplies needed for our business. In addition, the imposition of tariffs on certain foreign goods and the occurrence of a trade war or other governmental action related to tariffs or trade agreements or policies may adversely impact demand for our services, our costs, our customers and the U.S. economy. As noted above, the impact to our future operations and results of operations as a result of these global trends remains uncertain and we may face challenges including increases in costs for logistics and supply chains, intermittent supplier delays and shortages of certain components needed for our business, such as HVAC equipment, electrical equipment, steel and aluminum. These tariffs, restrictions and strained trade relations may affect our ability to source materials and products, potentially leading to increased costs and operational challenges and decreased demand for our offerings. We are closely monitoring the regulatory environment and actions of the current U.S. administration that could impact our business.

From time to time, as a result of macroeconomic conditions, we have been impacted by inflation, including escalating transportation, commodity and other supply chain costs and disruptions. We continue to monitor macroeconomic conditions to remain flexible and to optimize and enable our business to evolve as appropriate to address the challenges presented from these conditions. If our costs are subject to significant inflationary pressures, we may not be able to offset such higher costs through price increases, which could adversely affect our business, results of operations or financial condition.

Components of Results of Operations

Revenue

Revenue is derived from customer contracts, pursuant to which we provide engineering, consulting, installation and maintenance services for industrial and commercial buildings. Customer contracts typically have terms that span from one day to several years, though the vast majority of contracts are completed in less than one year. The majority of our contracts are fixed-price.

Cost of Revenue

Cost of revenue primarily consists of direct costs including labor, material and equipment, as well as overhead costs including project management, facilities, IT, vehicles and various third-party expenses, such as insurance, rentals and subcontractor costs.

Selling, General and Administrative

Selling, general and administrative expenses primarily consist of personnel costs, including wages, payroll tax, benefits and incentive compensation, as well as the costs of our real estate and IT services, integration costs for acquisitions after the acquisition date and various third-party professional fees.

Depreciation and Amortization

Depreciation and amortization expenses primarily consist of depreciation on property or equipment such as vehicles, computer equipment, leasehold improvements, tools and other equipment. The amortization of our intangible assets includes tradenames, customer relationships, contract backlog, and right of use assets of our finance leases.

Table of Conten t s

Acquisition-Related Costs

Acquisition-related costs are costs we incur to effect a business combination, such as legal and professional fees.

Changes in the Fair Value of Contingent Consideration Liabilities

Contingent consideration liabilities are related to business acquisitions as further described in "Item 8. Financial Statements and Supplementary Data, Note 4—Acquisitions ” in Notes to Consolidated Financial Statements. Changes in the fair value of contingent consideration liabilities are recorded to Changes in the fair value of contingent consideration liabilities on the Company’s Consolidated Statements of Operations. As of December 31, 2025 and 2024, there were no outstanding contingent consideration liabilities, though future business acquisitions may result in future contingent consideration liabilities.

Goodwill Impairment

Goodwill impairment includes the expense recorded in a reporting period for impairment when we determine that the carrying value of goodwill exceeds its fair value. We conduct our annual goodwill impairment testing at the beginning of our fourth quarter each year.

Equity in Earnings of Joint Venture

Equity in earnings of joint venture reflects our share of joint venture income or loss, as well as any impairment loss. Distributions received from the joint venture investment are accounted for under the cumulative earnings approach, which compares our cumulative distributions received from the joint venture against our cumulative equity in earnings of joint venture.

Interest Expense, Net of Capitalized Interest

Interest expense includes interest on the indebtedness, amortization of deferred debt issuance costs and debt issuing discounts, as well as gains and losses from interest rate related derivative instruments.

Interest Income

Interest income includes interest earned on our cash balances and short-term marketable securities.

Loss on Debt Extinguishment

Loss on debt extinguishment represents accelerated amortization of debt issuance costs related to early debt payment.

Credit Agreement Amendment Fees

Credit agreement amendment fees represent costs incurred in connection with our debt refinancings or amendments.

Income Tax Expense (Benefit)

We are subject to federal, state and local taxes based on income in the jurisdictions in which we operate. Accordingly, our effective tax rate is subject to significant variation due to several factors, including variability in our pre-tax and taxable income and loss and the mix of jurisdictions to which they relate, changes in how we do business, acquisitions, tax audit developments, changes in our deferred tax assets and liabilities, changes in statutes, regulations, case law and administrative practices, principles and interpretations related to tax and relative changes of expenses or losses for which tax benefits are not recognized.

Legence is subject to federal and state income taxes with respect to our allocable share of any taxable income or loss of Legence Holdings, as well as any stand-alone income or loss we generate. Legence Holdings is treated as a partnership for federal and state income tax purposes. Generally, entities characterized as a partnership for federal and state income tax purposes are not subject to entity-level income taxes. Legence Holdings’ taxable income or loss is passed through to its members, including Legence, which is responsible for its own U.S. federal and state income taxes. Certain other subsidiaries of Legence are treated as corporations and will file as a consolidated group in various jurisdictions within the United States, including both federal and state and local jurisdictions.

Table of Conten t s

Income taxes for these entities are provided for under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the consolidated financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to an amount that is more likely than not to be realized.

Factors Affecting the Comparability of Our Financial Results

Our future results of operations may not be comparable to the historical results of operations of our predecessor for the periods presented, primarily for the reasons described below.

Refer to “ Note 1—Nature of Operations ” for a summary of our Initial Public Offering and Corporate Reorganization, “ Note 12—Stockholders' Equity / Member’s Equity ” for our Secondary Offering, “ Note 13 — Stock-Based Compensation and Long-term Incentive Awards ” for our 2025 Omnibus Incentive Plan, and “ Note 16 — Tax Receivable Agreement ” in Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data."

Acquisitions

We have pursued and plan to continue to pursue acquisitions as part of our growth strategy, including acquisitions that expand our capabilities, give us access to new clients or extend our geographic reach. As a result of our acquisition strategy, our results include incremental revenues and expenses following the completion date of an acquisition, as well as various transaction expenses to support the completion of these acquisitions.

Public Company Expenses

As a result of being a publicly traded company, we incur incremental general and administrative expenses such as expenses associated with SEC reporting requirements, including annual and quarterly reports, SOX compliance expenses, expenses associated with listing our Class A Common Stock on the Nasdaq, independent auditor fees, legal fees, investor relations expenses, registrar and transfer agent fees, director and officer insurance expenses and director and officer compensation expenses. These incremental general and administrative expenses are not reflected in the historical financial statements of our predecessor. Additionally, we have hired additional employees and consultants, including accounting, finance, tax, human resources and legal personnel for the requirements of being a publicly traded company.

Income Taxes

Legence is subject to U.S. federal and state income taxes as a corporation. Our predecessor was treated as a pass-through entity for U.S. federal income tax purposes, and as such, was generally not subject to federal income tax at the entity level. However, several of the predecessor’s subsidiaries are corporations for tax reporting purposes and therefore require a U.S. federal and state income tax provision for that portion of such entities’ results.

On July 4, 2025, a reconciliation bill commonly referred to as the One Big Beautiful Bill Act (the “OBBB Act”) was signed into law, which includes a broad range of tax reform provisions that may affect our financial results. The OBBB Act allows an elective deduction for domestic research and development, a reinstatement of elective 100% first-year bonus depreciation, and modifications to the calculation for the excess business interest expense limitation under Section 163(j) of the Internal Revenue Code. Our analysis shows the OBBB Act did not have a material impact on our consolidated financial statements for the year ended December 31, 2025. We will continue to monitor regulatory guidance and interpretations as they are issued.

On September 12, 2025, Legence conducted its IPO through an Umbrella Partnership C-Corporation (UP-C) structure, and on December 16, 2025, Legence Corp. completed a secondary public offering on behalf of certain selling shareholders. As a result of these transactions, there are now public shareholders that own shares of Legence and those shareholders are subject to U.S. federal income tax on dividends received from Legence and on gains realized upon the sale or disposition of Legence shares. Because the public shareholders do not hold direct interests in Legence Holdings, they will not generally receive any direct flow-through of Legence Holdings’ tax attributes, such as losses or deductions, and will be subject to the standard rules applicable to shareholders of C corporations.

Engineering & Consulting : Engineering & Consulting segment revenue increased $124.7 million for the year ended December 31, 2025 compared to the year ended December 31, 2024. Approximately 80% of the revenue increase in the Engineering & Consulting segment resulted from the impact of acquisitions completed in 2024 and the impact of an acquisition completed in late 2025. The Engineering & Design service line increased by 22.8% primarily driven by higher demand from life sciences & healthcare clients and hospitality & entertainment clients within Other . The Program & Project Management service line increased by 17.9% primarily driven by greater demand from hospitality & entertainment clients within Other .

Installation & Maintenance : Installation & Maintenance segment revenue increased $327.2 million for the year ended December 31, 2025 compared to the year ended December 31, 2024, driven by $310.1 million of incremental revenue from the Installation & Fabrication service line. The revenue increase in the Installation & Fabrication service line is primarily due to greater demand from data centers & technology as well as life sciences & healthcare clients, partially offset by lower demand from mixed-use clients and hospitality & entertainment clients within Other. The $17.1 million increase in revenue from the Maintenance & Service service line is primarily due to greater demand from data centers & technology as well as life sciences & healthcare clients, partially offset by lower demand from clients within Other.

Gross Profit

Consolidated gross profit increased $105.2 million, or 24.4%, during the year ended December 31, 2025 compared to the year ended December 31, 2024. The increase is attributable to the results of our operating segments, which are discussed below.

Consolidated gross profit

Engineering & Consulting : The $33.8 million, or 16.5%, increase in gross profit for the year ended December 31, 2025 compared to the year ended December 31, 2024 was primarily attributable to higher revenue from the impact of acquisitions completed in 2024, partially offset by a lower gross margin. The decrease in gross margin reflects the impact of higher stock-based compensation related to legacy profit interest units paid for by entities outside of Legence as well as

Table of Conten t s

lower margin within our Engineering & Design service line, primarily from life sciences & healthcare, state & local government and education clients, partially offset by greater efficiency in customer fulfillment support costs.

Installation & Maintenance : The $71.4 million, or 31.6%, increase in gross profit for the year ended December 31, 2025 compared to the year ended December 31, 2024 was primarily attributable to revenue growth and higher gross margin in the Installation & Fabrication service line. The increase in gross margin was driven by strong project execution, partially offset by lower efficiency in customer fulfillment support costs, which includes higher stock-based compensation related to legacy profit interest units paid for by entities outside of Legence.

Selling, General & Administrative

Selling, general and administrative expenses increased by $99.7 million during the year ended December 31, 2025 compared to the year ended December 31, 2024. Approximately $12.5 million of the increase in selling, general and administrative expenses related to the full-year impact in 2025 for acquisitions completed in 2024. Compensation expense increased $70.8 million compared to the prior year largely due to an increase in fair value of profits interest awards as well as higher headcount. Professional fees increased $17.6 million primarily related to the preparation of our IPO while lease and related expenses increased $7.0 million.

Goodwill Impairment

During the year ended December 31, 2025, it was determined the carrying amount of goodwill for one reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in goodwill impairment of $25.0 million. The impairment was primarily driven by a decline in projected cash flows due to lower customer demand, extending sales cycles and project funding uncertainty in the alternative energy industry.

During the year ended December 31, 2024, it was determined the carrying amount of goodwill for one reporting unit in the Engineering & Consulting segment exceeded its fair value, resulting in goodwill impairment charges of $17.8 million. The impairment was primarily driven by a decline in projected cash flows due to lower revenue projections.

Long-Lived Asset Impairment

During the year ended December 31, 2025, it was determined the carrying amount of Long-lived assets for one asset group in the Engineering & Consulting segment exceeded fair value, resulting in Long-lived asset impairment of $2.4 million. The impairment was primarily driven by declining revenue, margins and cash flow projections.

Interest Expense

The increase in interest expense is primarily attributable to higher average borrowings during the year ended December 31, 2025 compared to the year ended December 31, 2024.

Loss on debt extinguishment

The loss on debt extinguishment is primarily due to accelerated amortization of debt issuance costs related to the early debt payment of $780.3 million during the year ended December 31, 2025.

Other Expense (Income), net

Other Expense (Income), net increased by $7.0 million during the year ended December 31, 2025 compared to the year ended December 31, 2024. The year ended December 31, 2025 includes $3.8 million for adjustments to an indemnification asset related to unrecognized tax benefits acquired in a prior acquisition, which is fully offset as an income tax benefit netted in Income tax expense on the Consolidated Statements of Operations and $2.9 million related to TRA liability remeasurements for changes in state income tax rates.

Income Tax Expense

Income tax expense was $22.2 million for the year ended December 31, 2025, and resulted in an effective tax rate of negative 40.2%, as compared to an income tax expense of $4.5 million for the year ended December 31, 2024 and an effective tax rate of negative 19.6%. These rates are lower than the federal statutory rate of 21%. The effective tax rate in the year ended December 31, 2025 was primarily due to a significant portion of the pre-tax loss being generated by pass-through entities that are not subject to income taxes at the Company level and an impairment that was not deductible for

Table of Conten t s

tax. The effective tax rate in the year ended December 31, 2024 was primarily due to a significant portion of the pre-tax loss being generated by pass-through entities that are not subject to income taxes at the Company level and unfavorable permanent adjustments including goodwill impairment, and was partially offset by a reduction in the Company’s deferred state tax rate.

Consolidated gross profit

Engineering & Consulting : The increase in gross profit was attributable to higher revenue partially offset by modestly lower gross margin resulting from lower sustainability consulting revenue, which typically generates higher margins. Additionally, 2023 gross profit benefited from $7.4 million in revenue related to one-time amendments to several contracts with a developer in exchange for discounted fees.

Installation & Maintenance : The increase in gross profit was primarily attributable to higher revenue. The increase in gross profit margin was driven by several larger projects with higher margins.

Selling, General & Administrative

The increase in selling, general and administrative expenses is primarily attributable to a $29.7 million increase in compensation costs during the period resulting from more headcount. Additionally, there was an increase in professional fees of $7.4 million as compared to the prior year related primarily to IT costs, acquisition-related costs and other costs related to our strategic initiatives.

Depreciation and Amortization

The increase in depreciation and amortization is attributable to a $10.9 million increase in the amortization of intangible assets and a $7.1 million increase in the depreciation of property and equipment, primarily from the full year impact of acquisitions completed in 2023 and the contribution from companies acquired in 2024.

Changes in the Fair Value of Contingent Consideration Liabilities

The decrease in changes in the fair value of contingent consideration liabilities is primarily attributable to the contingent earnout obligation associated with the Black Bear acquisition, which we completed in 2022. During the year ended December 31, 2023, the fair value of the contingent earnout obligation increased $27.0 million as the maximum earnout was achieved. We paid the earnout amount in 2024 and have no further obligations to Black Bear shareholders under the earnout agreement and as such did not recognize any changes in the fair value of the contingent earnout obligation during the year ended December 31, 2024.

Goodwill Impairment

During the year ended December 31, 2024, it was determined the carrying amount of goodwill for one reporting unit in the Engineering & Consulting segment exceeded its fair value, resulting in goodwill impairment charges of $17.8 million. The impairment was primarily driven by a decline in projected cash flows due to lower revenue projections. During the year ended December 31, 2023, it was determined the carrying amount of goodwill for one reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in goodwill impairment charges of $5.1 million. The impairment was primarily driven by a decline in projected cash flows due to lower revenue projections and investments in support functions.

Interest Expense, Net of Capitalized Interest

The increase in interest expense, net of capitalized interest is primarily attributable to additional borrowings. This includes $565.0 million of borrowings under the Term Loan Credit Facility during 2024, as well as the full year impact of $155.0 million of incremental borrowings under the Term Loan Credit Facility during 2023.

Table of Conten t s

Income Tax Expense (Benefit)

Income tax expense was $4.5 million in the year ended December 31, 2024, and resulted in an effective tax rate of negative 19.6%, as compared to an income tax benefit of $7.9 million in the year ended December 31, 2023 and an effective tax rate of 14.5%. These rates are lower than the federal statutory rate of 21%. The effective tax rate in the year ended December 31, 2024 was primarily due to a significant portion of the pre-tax loss being generated by pass-through entities that are not subject to income taxes at the Company level and unfavorable permanent adjustments including goodwill impairment, and was partially offset by a reduction in the Company’s deferred state tax rate. The effective tax rate in the year ended December 31, 2023 was primarily due to a significant portion of the pre-tax loss being generated by pass-through entities that are not subject to income taxes at the Company level and to taxable income in the tax paying C corporations.

Non-GAAP Financial Measures

Adjusted EBITDA and Adjusted EBITDA Margin are financial measures not presented in accordance with GAAP but are intended to provide useful and supplemental information to investors and analysts as they evaluate our performance. EBITDA is defined as earnings before interest and other financing expenses, taxes, depreciation and amortization. Adjusted EBITDA is defined as net loss adjusted to exclude, or otherwise reflect, interest expense, net of capitalized interest, interest income, income tax expense (benefit), depreciation and amortization, credit agreement amendment fees, goodwill impairment, long-lived asset impairment, net (gain) loss on sale and disposition of property and equipment, loss on debt extinguishment, changes in the fair value of contingent consideration liabilities, acquisition and integration costs, system deployment costs, strategic initiative costs, indemnification asset adjustments, Tax Receivable Agreement liability remeasurements, stock-based compensation expense and accelerated project sale. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenue. Adjusted EBITDA should not be considered an alternative to net loss that is derived in accordance with GAAP. Management believes that the exclusion of the above-described items from gross profit and net loss in the presentation of the non-GAAP measures identified above enables us and our investors to more effectively evaluate our operations period over period and to identify operating trends that might not be apparent due to, among other reasons, the variable nature of these items, both in value and frequency, period over period. In addition, management believes these measures may be useful for investors in comparing our operating results with those of other companies.

Our non-GAAP financial measures may not be comparable to similarly titled measures used by other companies, have limitations as analytical tools and should not be considered in isolation, or substitutes for analysis of our operating results as reported under GAAP. Additionally, we do not consider our non-GAAP financial measures superior to, or a substitute for, the equivalent measures calculated and presented in accordance with GAAP. Some of the limitations are that such measures:

• may exclude the recurring expenses of depreciation and amortization of property and equipment and definite-lived intangible assets and the assets being depreciated and amortized may have to be replaced in the future;

• do not reflect changes in our working capital needs;

• do not reflect the interest (income) expense on our indebtedness; or

• do not reflect the income tax (benefit) provision we are required to make.

In order to evaluate our business, we encourage you to review the financial statements included elsewhere in this filing, and not rely on a single financial measure to evaluate our business.

The following table provides a reconciliation of our Net Loss, the most directly comparable financial measure presented in accordance with GAAP, to Adjusted EBITDA, and a calculation of Adjusted EBITDA Margin for the periods presented herein (dollars in thousands):

Table of Conten t s

selected to provide the system for the client. The fee is typically earned and paid when the client enters into a binding contract with the project developer and permits to begin construction have been issued. If a contract is not signed or permits are not issued, Black Bear is typically not owed a fee from the project developer. In the fourth quarter of 2023, a project developer who had been selected for a large number of projects by Black Bear’s clients offered to immediately pay Black Bear all of the fees that Black Bear would earn in the future if all of the projects received permits, provided that Black Bear would agree to discount the fee amounts. Black Bear agreed to discount the fee amounts and recorded significantly higher revenues than would be typical in a quarter. Given the unique nature of the transaction, we consider it to be non-recurring in nature. This adjustment is to eliminate the approximately $7.4 million profit we recorded from the transaction.

Backlog and Awarded Contracts and Book-to-Bill Ratio

We track backlog and awarded contracts. We believe that these measures enable us to more effectively forecast our future results and working capital needs, as well as better identify future operating trends that may not otherwise be apparent. We believe this measure is also useful for investors in forecasting our future results and comparing us to our competitors. We also track our book-to-bill ratio, based on backlog and awarded contracts, for the same reasons. Our backlog is equivalent to our remaining performance obligations. As a result, there are no adjustments being made that would be reflected in a reconciliation. Our methodology for calculating backlog and awarded contracts or book-to-bill ratio may not be consistent with methodologies used by other companies.

Our backlog and awarded contracts measure has two components: backlog and awarded contracts. Backlog represents, as of any date of determination, the expected revenue values of the remaining performance obligations under our contracted fixed-price projects. Awarded contracts represents as of any date of determination, the expected revenue values of projects awarded to us following a request for proposals but for which a formal contract has not yet been signed. We only include fixed-price contracts in our backlog and awarded contracts because they have defined revenue values. We do not include cost-plus contracts, which are primarily generated in our Maintenance & Service service line, in our backlog and awarded contracts because their total revenue values are not known. Historically, cost-plus projects have comprised a relatively small portion of our revenue. We calculate our book-to-bill ratio by taking our additions to backlog and awarded contracts, excluding additions that were attained through acquisition, for the period, and dividing it by revenue from fixed-price contracts for the same period. A book-to-bill ratio of 1.0 indicates that we are booking backlog and awarded contracts at the same pace as we are recognizing revenue, suggesting stable revenue in future periods. A book-to-bill ratio above 1.0 indicates that backlog and awarded contracts are outpacing revenue, which could indicate an increase in revenue in future periods. Conversely, a book-to-bill ratio below 1.0 indicates that backlog and awarded contracts are trailing revenue, which could indicate a decrease in future revenue. Given that backlog and awarded contracts and book-to-bill ratio are operational measures and that our methodology for calculating backlog and awarded contracts and book-to-bill ratio does not meet the definition of a non-GAAP measure, as that term is defined by the SEC, a quantitative reconciliation for each is not required nor provided.

The increase in backlog and awarded contracts from December 31, 2024 to December 31, 2025 resulted from an increase in awards in both segments. The increase in Engineering & Consulting was primarily driven by new projects within the state & local government and life sciences & healthcare client end markets. The increase in Installation & Maintenance was primarily driven by new projects within the data centers & technology client end market. The increase in backlog and awarded contracts from December 31, 2023 to December 31, 2024 resulted from an increase in awards in both segments. The increase in Engineering & Consulting was primarily driven by new projects within the education client end market and additional backlog from the acquisition of P2S and AMA. The increase in Installation & Maintenance was primarily driven by new projects within the life sciences & healthcare and data centers & technology client end markets.

Liquidity and Capital Resources

Overview

As of December 31, 2025 and 2024, our primary sources of liquidity included cash and cash equivalents of $230.2 million and $81.2 million, respectively, and $194.3 million and $84.8 million, respectively, available to be borrowed under the Revolving Credit Facility and cash flows from operations as of December 31, 2025 and 2024. We expect our primary sources of liquidity to be cash flows from operations, borrowings incurred under our Revolving Credit Facility or proceeds from offerings of debt or equity securities. Access to additional liquidity, such as a further increase in the capacity under our existing Revolving Credit Facility or a new financing arrangement, will be dependent upon our future financial position and debt market conditions.

To date, our primary uses of capital have included funding working capital, capital expenditures for equipment used in our business, acquisitions and refinancing or repayment of debt and associated interest. Although our capital expenditures have historically been low relative to our revenues, we expect an increase in future periods due to our investment in fabrication capacity expansion within our Installation & Maintenance segment.

Although we cannot provide any assurance that our cash flows from operations will be sufficient to fund our operations or that additional capital will be available to us on acceptable terms, or at all, we believe our primary sources of liquidity are sufficient to fund our ongoing working capital, investing and financing requirements for at least the next twelve months and beyond. In the event that we require additional capital, we may seek to raise funds at any time through equity, equity-linked arrangements and debt. If we are unable to raise additional capital when desired and on reasonable terms, our business, results of operations, and financial condition would be adversely affected. Refer to "Part I, Item 1A. Risk Factors” for additional information.

Cash Flows

The information presented below was derived from our Consolidated Statements of Cash Flows within the Consolidated Financial Statements and summarizes cash flow activity (dollars in thousands):

Year Ended December 31,

Cash provided by (used in):

Operating activities

Investing activities

Financing activities

Increase (decrease) in cash and cash equivalents and restricted cash

Please refer to the supplemental cash flow information included in “ Note 22—Other Financial Information ” in Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for further details.

Operating Activities

Cash flow from operating activities is primarily influenced by the level of revenue we generate and the gross margin we earn on that revenue. It is also influenced by the timing of working capital investment associated with the services that we provide. Our working capital needs may increase when we commence large volumes of work under circumstances where project costs are required to be paid before the associated receivables are billed and collected. Our management strives to negotiate payment terms that minimize the working capital investment that we are required to make in connection with large projects. Additionally, changes in project timing due to delays or accelerations and other economic, regulatory, market and political factors may affect customer spending and, thus, impact cash flows from operating activities. We typically require the most working capital during the second half of the year as activity levels increase in the spring and summer months and less working capital in the first half of the year as activity levels decrease and we receive final payments on completed jobs.

Cash flows provided by operating activities increased by $227.6 million during 2025 compared to 2024. The increase mainly reflects fluctuations in the primary components of working capital, as detailed in the Consolidated Statements of Cash Flows. Operating cash flows from contract liabilities increased by $186.7 million, primarily due to increased billings net of recognized revenue. Operating cash flows from accounts payable increased by $107.2 million, primarily due to increased business activity and timing of payments. Additionally, operating cash flows from accrued and other current liabilities increased by $22.7 million, primarily because there were no payments of contingent consideration during 2025 compared to $32.5 million during 2024. These increases are partially offset by a $168.2 million decrease in operating cash flows from accounts receivable and contract assets. The change in accounts receivable and contract assets is primarily driven by higher revenue and the timing of billing and collection. The impact of adjustments for non-cash items was mostly offsetting in nature and is detailed on the Consolidated Statements of Cash Flows.

Cash flows from operating activities decreased by $4.6 million during 2024 compared to 2023. This decrease is primarily attributable to fluctuations in the main components of working capital, as detailed in the Consolidated Statements of Cash Flows. Specifically, net loss decreased by $18.4 million, while the benefit was partially offset by a $22.5 million decrease in cash provided by the effects of changes in operating assets and liabilities. The decrease from changes in operating assets and liabilities is primarily attributable to an increase in contract assets of $27.3 million due to increased revenue and contract retentions and the decrease in accrued and other current liabilities of $37.9 million, most of which related to the payment of contingent earnouts from acquisitions in excess of the amounts of the acquisition-date fair value of the liability. These changes were partially offset by other operating assets and liabilities, primarily an increase in accounts payable of $15.7 million due to the volume and timing of payments to vendors, and a $98.9 million benefit from changes in accounts receivable due to the timing of collections from customers. The impact of adjustments for noncash items was mostly offsetting in nature and is detailed on the Consolidated Statements of Cash Flows.

Table of Conten t s

Investing Activities

Cash flows used in investing activities primarily consist of payments for the acquisition of businesses, capital expenditures and proceeds from the sale of property and equipment.

Cash flows used in investing activities decreased by $189.9 million during 2025 compared to 2024. The decrease is primarily attributable to a decrease of $208.7 million in consideration paid for acquisitions, partially offset by an $18.9 million increase in purchases of property and equipment.

Cash flows used in investing activities increased by $110.1 million during 2024 compared to 2023. The increase is primarily attributable to a $105.4 million increase in consideration paid for acquisitions.

Financing Activities

Financing cash flows primarily consist of the issuance and repayment of short-term and long-term debt, debt issuance costs, contingent earnouts from acquisitions, financing lease payments, and cash distributions and contributions to and from Legence Parent.

During 2025, cash used in financing activities was $53.8 million compared to cash provided by financing activities of $207.0 million during 2024, which is a $260.8 million decrease in cash flows from financing activities. The change is impacted by a $505.4 million decrease in term loan borrowings and an $838.5 million increase in term loan payments in 2025 compared to 2024. In 2025, the Company received $780.2 million of net IPO proceeds and used those proceeds and cash on hand to pay $28.1 million of outstanding offering costs and prepay a portion of the term loan. The rest of the change is primarily related to $301.6 million in distributions to Legence Parent and $32.5 million of payments of contingent consideration, both of which occurred in 2024.

Cash flows provided by financing activities increased by $78.5 million during 2024 compared to 2023. The increase is primarily attributable to a $410.0 million increase in proceeds from borrowings, partially offset by the $300.1 million increase in the cash distributions to Legence Parent and the $27.0 million increase in the payment of contingent earnouts from acquisitions.

Financial Statements and Supplementary Data" for further information.

Credit Agreement

On December 16, 2020, Legence Holdings entered into a credit agreement with Jefferies Finance LLC as the administrative agent for a group of lenders, which provided for (a) a term loan credit facility, (b) a delayed draw term loan credit facility and (c) a revolving credit facility. The term loan matures on December 16, 2031, and is secured by substantially all assets of the Company, subject to customary exclusions.

Table of Conten t s

On February 6, 2025, Legence Holdings amended the credit agreement to reduce the interest rate applicable to borrowings of term loans or delayed draw term loans and extend the maturity date applicable to the Term Loan Credit Facility and the Delayed Draw Term Loan Credit Facility by one year from December 16, 2027 to December 16, 2028. The amendment also removed the 0.10% credit spread adjustment applicable to borrowings of term loans that are SOFR loans.

On September 8, 2025, Legence Holdings and certain of its subsidiaries amended the credit agreement to, among other things, facilitate the Corporate Reorganization.

As a result of the IPO, the interest rate for term loans, revolving credit loans and the fee rate on letters of credit was reduced by 0.25%.

On September 15, 2025, the Company used IPO proceeds and cash on hand to prepay $780.3 million of the term loan debt, which reduced the outstanding term loan balance to $797.8 million as of September 30, 2025.

On October 30, 2025, Legence Holdings and certain of its subsidiaries entered into Amendment No. 11 to the credit agreement to, among other things, refinance and replace the previously existing (i) $797.8 million term loan facility with a $797.8 million term loan facility that extends the maturity date by three years to December 16, 2031 and reduces its applicable interest rate by 0.25% to the Secured Overnight Financing Rate (“SOFR”) plus 2.25% and (ii) $90.0 million revolving credit facility with a $200.0 million revolving credit facility that extends its maturity date by approximately four years to September 22, 2030 and sets its applicable interest rate at SOFR plus 2.25%, in alignment with the replacement term loan credit facility.

Subject to the requirements of the credit agreement, Legence Holdings may also be required, as applicable, to make additional principal payments based on its excess cash flow, as defined in the agreement.

Under the terms of the credit agreement, Legence Holdings and its subsidiaries may be able to incur substantial additional indebtedness in the future, subject to certain conditions.

The credit agreement contains a springing financial maintenance covenant that requires the First Lien Net Leverage Ratio not to exceed 8.50 to 1.00 if certain testing conditions are satisfied. The credit agreement generally defines this as the ratio of first lien secured indebtedness (net of cash) to consolidated pro forma adjusted EBITDA for the preceding four fiscal quarters. The springing financial maintenance covenant is only tested if, as of the last day of each fiscal quarter, the amount of loans and/or letters of credit outstanding under the Revolving Credit Facility is greater than 35% of the aggregate revolving credit commitments. The springing financial maintenance covenant was not required to be tested during the periods presented in the Consolidated Financial Statements.

The credit agreement includes customary covenants restricting the ability of Legence Holdings and its subsidiaries to, among other things, incur additional indebtedness, sell or convey assets, make loans to or investments in others, enter into mergers, incur liens and pay dividends or distributions.

Other Notes Payable

The Company holds various other promissory notes payable in connection with certain acquisitions. These notes payable comprise a small portion of our outstanding indebtedness. Please refer to “Item 8. Financial Statements and Supplementary Data, Note 9—Debt ” in Notes to Consolidated Financial Statements for further information.

Tax Receivable Agreement

In connection with the consummation of our IPO, we entered into the TRA with the TRA Members. This agreement generally provides for the payment by us to the TRA Members of 85% of the net cash savings, if any, in U.S. federal, state and local income tax that we (a) actually realize with respect to taxable periods ending after our IPO or (b) are deemed to realize in the event the TRA terminates early at our election, as a result of our breach or upon a change of control (as defined under the TRA, which includes certain mergers, asset sales and other forms of business combinations and certain changes to the composition of our Board) with respect to any taxable periods ending on or after such early termination event, in each case, as a result of (i) our allocable share of existing tax basis acquired in connection with our IPO and increases to such allocable share of existing tax basis; (ii) our utilization of certain tax attributes of the Blocker Entities; (iii) Basis Adjustments; and (iv) certain additional tax benefits arising from payments made under the TRA. We will retain

Table of Conten t s

the benefit of the remaining 15% of these cash savings, if any. If the TRA terminates early, we could be required to make a substantial, immediate lump-sum payment.

We expect that the payments that we will be required to make under the TRA could be substantial. The exact amount of expected future payments under the TRA is dependent upon a number of factors, including the Company’s cash tax savings, the timing of exercises of the Exchange Right, the enacted tax rate in the years in which it utilizes tax attributes subject to the TRA, and current taxable income forecasts. These estimated rates and forecasts are subject to change based on actual results and realizations, which could have a material impact on the liability to be paid. Due to the uncertainty of these factors, we cannot precisely quantify the likely tax benefits we will realize. Any payments made by us to the TRA Members under the TRA will not be available for reinvestment in Legence Holdings (or indirectly, its business) and generally will reduce the amount of overall cash flow that might have otherwise been available to us. We expect to fund the required payments under the TRA with our actual cash tax savings generated by the exchanges of LGN Units in the UP-C structure. Our ability to satisfy our long-term liquidity requirements depends on our future operating performance, which is affected by and subject to prevailing economic conditions, market conditions in our industry and financial, business and other factors that we will not be able to predict or control.

The term of the TRA commenced upon the completion of the IPO and will continue until all such tax benefits have been utilized or expired and all required payments are made, unless we exercise our right to terminate the TRA (or the TRA is terminated due to other circumstances, including our breach of a material obligation thereunder or certain mergers or other changes of control) by making the termination payment specified in the agreement.

Material Cash Requirements

As of December 31, 2025, our material cash requirements primarily consist of obligations under our lease arrangements and financing arrangements. These obligations and their expected timing on future cash flows and liquidity are summarized within “ Note 8—Leases ” and “ Note 9—Debt ” in Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data", respectively (dollars in thousands).

Contingent Obligations

We have various contingent obligations that we anticipate could require the use of cash based on contractual obligations as of December 31, 2025; however, the final amount payable or the timing may not be fixed and determinable. Such contingent obligations include the following:

• Some of our customers require us to secure surety bonds from reputable financial institutions to guarantee execution on certain projects. In the event Legence or its subcontractors fail to meet its performance obligations, customers have the option to request the surety bond provider fund the completion of the project using other service providers. Under the terms of these agreements, we are liable for any disbursement made by the bonding company because of our failure to perform. Surety bonds expire at various times ranging from final completion of a project to a period extending beyond contract completion in certain circumstances. Such amounts can also fluctuate from period to period based upon the mix and level of our bonded operating activity. For example, public sector contracts require surety bonds more frequently than private sector

Table of Conten t s

contracts, and accordingly, our bonding requirements typically increase as the amount of our public sector work increases. Our estimated maximum exposure as it relates to the value of the surety bonds outstanding is lowered on each bonded project as the cost to complete is reduced, and each commitment under a surety bond generally extinguishes concurrently with the expiration of its related contractual obligation. As of December 31, 2025 and 2024, $561.5 million and $384.2 million, respectively, of backlog and awarded contracts was subject to surety bond obligations. In the eleven years prior to December 31, 2025, we did not receive a claim for liquidated damages in excess of $100,000.

• As part of our normal course of business, we offer guaranteed energy savings to customers under certain contracts. As of December 31, 2025 and 2024, total guarantees were $307.4 million and $308.2 million, respectively. Should the guaranteed energy savings not be achieved, these guarantees would become due to the customers. Historically, we have not incurred notable losses in connection with these guarantees.

• We have standby letters of credit that are secured through the revolving line of credit. Obligations under these letters of credit are not normally called, as we typically comply with the underlying requirements. As of December 31, 2025 and 2024, we had $5.7 million and $5.2 million, respectively, in standby letters of credit primarily related to the deductibles of insurance policies. Please refer to “Item 8. Financial Statements and Supplementary Data, Note 9—Debt ” in Notes to Consolidated Financial Statements for further information.

• We make payments for collective bargaining agreements, multiemployer pension plan liabilities and liabilities related to our deferred compensation and other employee benefit plans, as discussed in “Item 8. Financial Statements and Supplementary Data, Note 13—Stock-Based Compensation and Long-term Incentive Awards ” and “ Note 17—Union-Sponsored Pension Plans and Other Employee Benefit Plans ” in Notes to Consolidated Financial Statements.

Critical Accounting Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our Consolidated Financial Statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Our significant accounting policies are discussed in the “Item 8. Financial Statements and Supplementary Data, Note 2—Summary of Significant Accounting Policies ” in Notes to Consolidated Financial Statements. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to areas involving a significant level of estimation uncertainty and have had or are likely to have a material impact on our financial statements.

Revenue Recognition

The Company recognizes revenue at the time the related performance obligation is satisfied by transferring the promised good or service to its customers. A good or service is considered to be transferred when the customer obtains control. The Company can transfer control of a good or service and satisfy its performance obligations either over time or at a point in time, though the majority of the Company’s contracts have over time performance obligations.

Management has concluded performance obligations related to construction and service contracts are satisfied over time because the Company’s performance typically creates or enhances an asset that the customer controls. The Company primarily measures the progress toward complete satisfaction of the performance obligation(s) using an input method (i.e., “cost-to-cost”), though some contracts use an output method (i.e., “milestone achievement”) when our performance does not produce significant amounts of work in process prior to complete satisfaction of such performance obligation(s).

The accuracy of the Company’s revenue and profit recognition in each year at the balance sheet date depends on the accuracy of management’s estimates of the cost to complete each project as well as variable consideration. There are several factors that can contribute to changes in estimates of contract cost and profitability, such as changes in project scope, input costs and productivity, among others. Such factors may cause fluctuations in gross profit and gross profit margin from period to period. These changes may have a significant impact on the financial statements. At the time a loss on a contract becomes probable, the entire amount of the estimated loss is accrued. Management monitors for circumstances that may affect the accuracy of its estimates, and material changes in estimates are disclosed accordingly.

Table of Conten t s

Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable assets and liabilities of the acquired business. Goodwill is not subject to amortization but is tested for impairment at the reporting unit level, which represents the operating segment level or one level below the operating segment level for which discrete information is available. Goodwill is evaluated for impairment on an annual basis in the fourth quarter of the fiscal year and on an interim basis if events or circumstances arise which indicate that the carrying value of goodwill may not be recoverable from future cash flows.

Fair values of reporting units are estimated based on a market approach and an income approach. The income approach utilizes discounted future cash flows and assumptions critical to the fair value estimate of the discounted cash flow model including revenue growth rates, forecasted EBITDA margins and discount rate. The market approach utilizes market multiples of EBITDA margin on invested capital from comparable publicly traded companies. During the year ended December 31, 2025, it was determined the carrying amount of goodwill for one reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in goodwill impairment charges of $25.0 million. The impairment was primarily driven by a decline in projected cash flows due to lower customer demand, extending sales cycles and project funding uncertainty in the alternative energy industry. As of December 31, 2025, all other reporting units had fair value estimates exceeding carrying values by at least 19%, except for two reporting units in the Engineering & Consulting segment. These reporting units had a combined goodwill balance of $88.3 million with fair value exceeding carrying value by less than 10%.

During the year ended December 31, 2024, it was determined the carrying amount of goodwill for one reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in goodwill impairment charges of $17.8 million. The impairment was primarily driven by a decline in projected cash flows due to lower revenue projections. During the year ended December 31, 2023, it was determined the carrying amount of goodwill for one reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in goodwill impairment charges of $5.1 million. The impairment was primarily driven by a decline in projected cash flows due to lower revenue projections and investments in support functions.

There are inherent uncertainties related to these factors and management’s judgment in applying them to the analysis of goodwill impairment. It is possible that changes in facts, judgments and assumptions made in estimating the fair value of reporting units could occur, resulting in possible impairment in the future.

Tax Receivable Agreement

The TRA generally provides for the payment by us of 85% of the net cash savings, if any, we realize, or are deemed to realize, as a result of certain tax attributes and benefits covered by the TRA.

We estimate our obligation under the TRA utilizing various assumptions set forth in the TRA, including: (i) a constant combined federal and state corporate tax rate of 26.73%; (ii) we have sufficient taxable income to fully utilize the tax benefits; and (iii) no material changes in tax law. Because the timing and amount of realized tax savings depend on future taxable income, stock price, and exchange activity, actual TRA payments could differ materially from estimates. Estimating future taxable income is inherently uncertain and requires judgment. Refer to “Item 8. Financial Statements and Supplementary Data, Note 1 6 —Tax Receivable Agreement ” in Notes to Consolidated Financial Statements included elsewhere in this filing for further information.

Income Taxes

We utilize the asset and liability approach in reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that is more likely than not to be realized.

Under the provisions of ASC 740-10 Income Taxes, the Company evaluates uncertain tax positions by reviewing against applicable tax law all positions taken by the Company with respect to tax years for which the statute of limitations is still open. ASC 740-10 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits.

Acquisitions and Valuation of Intangible Assets

We assign purchase consideration to the assets acquired and liabilities assumed as of their acquisition dates based on their fair value. We record our acquisitions under the acquisition method of accounting, and the total purchase price is allocated to the acquired net tangible and identifiable intangible assets based on their fair values as of the acquisition dates. Determining the fair value of certain long-lived assets, specifically intangible assets, requires judgment and often involves the use of significant estimates and assumptions.

The estimated fair value of identified intangible assets are Level 3 fair value measurements and are determined using discounted cash flow techniques. Fair value is estimated using a multi-period excess earnings method for customer relationships and backlog and a relief from royalty method for trade names. The significant assumptions used in estimating fair value of customer relationships and backlog include (i) the estimated life the asset will contribute to cash flows, such as remaining contractual terms, (ii) revenue growth rates and EBITDA margins, (iii) attrition rate of customers, and (iv) the estimated discount rates that reflect the level of risk associated with receiving future cash flows. The significant assumptions used in estimating fair value of trade names include discount rates and estimated royalties that would be paid to license a comparable asset. The royalty rates used in this method are based on published comparable market royalty transactions.
