Reworded

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

Added

The MEPC systems services industry is highly competitive and fragmented, with numerous regional and national providers offering similar services in the geographic markets in which we operate. We compete based on price, technical expertise, experience, reputation, and operational capabilities. Price is often a primary factor in contract awards, particularly for smaller or less complex projects, which may enable smaller competitors with lower cost structures to win work based on price alone.

Added

We also expect competition from the in-house service organizations of our customers who have employees who perform service and maintenance work similar to the services we provide as part of our ODR segment. Vertical consolidation is also expected to intensify competition in the industry. We can offer no assurance that our existing or prospective customers will continue to outsource specialty contracting services in the future. In addition, new and emerging technologies and service models may further alter competitive dynamics in the industry.

Added

If we are unable to compete effectively, including maintaining competitive pricing without adversely affecting our margins, we could experience reduced market share, lower profitability, and/or slower growth. Our results of operations could also be adversely affected if we are required to reduce prices to remain competitive.

Removed

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

Reworded

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

Reworded

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

Reworded

Our contract backlog is subject to unexpectedadjustments, adjustmentsdelays and cancellations and could be an uncertain indicator of our future earnings.

Removed

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

Removed

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

Removed

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

Removed

•on-site conditions that differ from those described in the original bid or contract;

Removed

•failure to include required materials, equipment, or work in a bid, or the failure to properly estimate the quantities or costs needed to complete a lump sum or guaranteed maximum price contract;

Removed

•contract or project modifications creating unanticipated costs not covered by change orders;

Removed

•failure by the customer, owner or general contractor to properly approve and authorize change orders for work that is required and as a result, the inability to bill and collect for the value of the work performed;

Removed

•failure by suppliers, vendors, subcontractors, designers, engineers, consultants, joint venture partners or customers to perform their obligations;

Removed

•delays in quickly identifying and taking measures to address issues which arise during contract execution;

Removed

•changes in availability, proximity and costs of materials and equipment, including pipe, sheet metal, other construction materials and mechanical, electrical and plumbing equipment;

Removed

Removed

•citations issued by any governmental authority, including OSHA;

Removed

•unexpected labor conditions, shortages, strikes or work stoppages in general causing delays in completion, or acceleration of the contracted work to maintain milestone completion dates, which could cause losses due to not meeting estimated production targets;

Removed

•installation productivity rates different than the rate that was estimated;

Removed

•changes in applicable tariffs, laws and regulations;

Removed

Removed

•fraud, theft or other improper activities by suppliers, vendors, subcontractors, designers, engineers, consultants, joint venture partners, customers or our own personnel; and

Removed

•mechanical or performance problems with equipment.

Removed

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

Reworded

OurA failureU.S. togovernment obtainshutdown newor agreementsdelays andin renewfederal existing agreementsappropriations could haveadversely a material adverse effect onaffect our business, financial conditionbusiness and results of operations.

Added

Our business is affected by macroeconomic, political, and regulatory conditions that influence the markets in which we operate. While the majority of our revenue is derived from private sector customers, we also perform work under contracts with U.S. federal, state, and local government agencies. Any partial or full shutdown of the U.S. government, delays in appropriations, uncertainty regarding the availability of government funds, or interruptions in government operations could result in the suspension, delay, or termination of government contracts, postponement of payments under existing contracts, or delays in the award of new contracts.

Added

In addition, our customers, suppliers, and partners may rely on government funding, approvals, or regulatory actions that may be suspended, delayed, or limited during a shutdown. These disruptions could postpone the start of projects, extend permitting timelines, or impact demand for our services. A prolonged or repeated government shutdown could also contribute to broader economic uncertainty, reduce public and private investment activity, and slow decision-making by our customers. There can be no assurance that government operations will continue without interruption, and any such disruptions could materially and adversely affect our financial condition, results of operations, liquidity, and overall business prospects.

Added

Because we bear the risk of cost overruns on many of our contracts, we may experience reduced profitability or incur losses if actual costs exceed our estimates.

Added

Many of our contracts are priced based on estimates and assumptions regarding future costs, including labor availability and wage rates; material, equipment, energy, and transportation costs; productivity levels; site conditions; permitting requirements; weather conditions; and other factors that are outside of our control. Inflationary pressures, including increases in labor, material, and equipment costs, as well as the imposition of tariffs or changes in trade policies, could increase our actual costs above those assumed at the time a contract is bid or negotiated. If our estimates or assumptions prove inaccurate, or if we are unable to effectively manage project execution, we may experience cost overruns that reduce project profitability or result in losses.

Added

Actual costs and gross profit on our contracts may differ, sometimes materially, from original projections due to factors such as unanticipated site conditions; changes in labor availability, skill levels, or productivity; supply chain disruptions; increases in commodity prices; delays in obtaining permits or approvals; adverse weather conditions; failures by subcontractors, suppliers, or other third parties to perform as expected; or delays in identifying and addressing execution issues. Inflationary cost increases or tariffs that are not recoverable through contractual price adjustments or change orders could further compress margins, particularly on longer-duration projects.

Added

Certain contracts also require us to meet specified completion dates or performance standards, and in some cases we guarantee project completion or acceptance by a defined schedule. Failure to meet these requirements may result in additional costs, reduced margins, or liability for liquidated or consequential damages. Performance issues on individual projects may also harm our reputation with customers and adversely affect our ability to secure future work.

Added

Many of our contracts contain provisions that allocate or shift these risks to us, including in circumstances where the customer may be partially responsible. We are not always able to pass such risks through to subcontractors or suppliers. While customers may agree to equitable contract adjustments under certain circumstances, there can be no assurance that such relief will be granted. Increased use or stricter enforcement of risk-shifting contractual provisions, combined with sustained inflation or changes in tariff regimes, could materially and adversely affect our financial position, results of operations, and cash flows.

Added

Our failure to obtain new customer agreements or renew existing agreements at current or more favorable terms could adversely affect our business, financial condition and results of operations.

Added

Our business depends on our ability to secure new customer agreements and to renew existing agreements in order to maintain and grow revenue. The process for obtaining new work or renewing existing arrangements is often competitive, complex, and subject to lengthy sales and selection cycles. These processes are influenced by market conditions, customer budget constraints, timing of contract expirations, pricing pressures, and other factors that are outside of our control.

Added

If we are unable to successfully compete for new agreements or renew existing agreements on acceptable terms, or if renewals are delayed, reduced in scope, or repriced at lower margins, our backlog, revenue, and operating results could be adversely affected. In addition, a reduction in awarded or renewed work could lead to lower utilization of our workforce and resources, which could further pressure margins and profitability.

Removed

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

Reworded

TimingThe timing of the awardaward, commencement and performance of new contracts couldmay havecause anvariability adverse effect onin our operating results and cash flow.flows.

Added

The timing of contract awards is inherently unpredictable and largely outside of our control. Project awards often involve competitive bidding processes and complex, lengthy negotiations, and may be affected by factors such as customer decisions to delay or cancel projects, financing conditions, governmental approvals, commodity price fluctuations, environmental conditions, and overall economic and market conditions. We may not win contracts that we pursue for a variety of reasons, including pricing, customer perceptions of our capabilities, competitive dynamics, or our unwillingness to accept certain contractual risks that is requested by the customer.

Added

Although a significant portion of our revenue is derived from smaller, lower-risk projects, our results of operations may fluctuate from period to period depending on the timing and size of contract awards, the commencement of work on newly awarded projects, and the progress of work on larger contracts. Delays in the start or execution of awarded projects may result in revenue and cash flows being realized later than anticipated.

Added

Uncertainty in the timing of project awards and execution may also make it difficult to efficiently align our workforce and resources with project demand. In anticipation of expected project activity, we may incur labor and overhead costs before revenue is realized. If anticipated projects are delayed or not awarded, these costs could adversely affect our profitability.

Removed

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

Removed

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

Reworded

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

Added

Such adjustments, if substantial, could have a material adverse effect on our financial position, results of operations and cash flows.

Added

We may be unable to recover additional claimed costs on projects, which could adversely affect our profitability and liquidity.

Removed

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

Reworded

In certain circumstances, we assert or have asserted claims against project owners, contractors, owners,subcontractors, engineers, consultants, subcontractors or othersother parties involved in a project for additional costs exceedingincurred the contract price or for amounts not included inbeyond the original contract price.

Added

Recoveries related to claims may be material in the periods in which they are resolved or become probable and estimable. If actual recoveries are less than amounts previously estimated, we may be required to reduce or reverse previously recognized revenue or profit, which could result in significant volatility in our operating results and, in some cases, cause us to report losses in a given period. Conversely, settlements in excess of recorded estimates could increase revenue and profit in the period of resolution.

Removed

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

Reworded

In addition, when these types of claims are made, we may be required to use or have used working capital to coverfund cost overruns pending the resolution of the relevantwhile claims remain unresolved and may incur additional costs whenin pursuing such potential recoveries.

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

Reworded

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

Reworded

The Company operates in two segments, (i) ODR, in which the Company performs owner direct projects and/or provides maintenance or service primarily on mechanical, plumbing or electricalMEPC systems, building controls and specialty contracting projects to existing buildings direct to, or assigned by, building owners or property managers,operators, and (ii) GCR, in which the Company generally manages new construction or renovation projects that involve primarily mechanical,MEPC plumbing, or electrical servicessystems awarded to the Company by general contractors or construction managers. The Company's work is primarily performed under fixed-price, modified fixed-price, and time and materials contracts over periods of typically less than two years.

Added

The Company’s revenue is primarily derived from construction-type and services contracts to deliver MEPC systems services to its customers. Such work is primarily performed under fixed-price, modified fixed-price, and time and materials contracts over periods of typically less than two years.

Added

Construction-type contract revenue is primarily derived from fixed-price and modified fixed-price contracts. For the majority of these contracts, the Company’s performance obligations are satisfied over time because the customer controls the asset as it is created or enhanced or because the Company’s performance does not create an asset with an alternative use and the Company has an enforceable right to payment for performance completed to date. For contracts satisfied over time, the Company recognizes revenue using an input method based on costs incurred relative to total estimated costs at completion (the cost-to-cost method), which management believes depicts the transfer of control of services to the customer. The Company believes its extensive experience with MEPC systems projects, together with its internal cost estimation and review processes, enables it to reasonably estimate contract costs and mitigate the risk of cost overruns.

Added

With respect to service contracts, the Company’s service arrangements generally include (i) fixed-price service contracts, typically for maintenance, repair and retrofit work over a period, commonly one year, and (ii) time and materials or similar service work performed on an as-needed basis. Revenue from fixed-price service contracts is generally recognized over time on a systematic basis that depicts performance over the contract term, which is typically on a straight-line basis when services are provided evenly over the contract period. Revenue derived from time and materials and other service work is recognized when the services are performed.

Removed

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

Reworded

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

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

Total revenue for the year ended December 31, 2025 increased by $128.0 million, or 24.7%, to $646.8 million, compared to $518.8 million for the year ended December 31, 2024. The increase in revenue was primarily attributable to the impact of recent acquisitions completed in the second half of 2024 and July 2025. The Company’s organic operations increased $18.9 million and the incremental increase from acquisition-related revenue for 2025 was $109.1 million. Acquisition-related revenue represents incremental revenue generated in 2025 by acquired businesses only for the twelve-month period subsequent to their respective acquisition dates. After such period, the results of acquired businesses are included within the Company’s organic operations, and period-over-period changes are discussed on a combined basis.

Added

ODR revenue for the year ended December 31, 2025 increased by $140.2 million, or 40.6%, to $485.7 million, compared to $345.5 million for the year ended December 31, 2024. This increase was driven by the Company’s continued focus on accelerating growth within its ODR business, as well as incremental revenue contributions from the Pioneer Power, Consolidated Mechanical and Kent Island acquisitions. These acquisitions contributed approximately $81.4 million of the ODR revenue increase during 2025. The remaining increase of $58.8 million reflects organic growth driven by higher project volume within the Company’s ODR segment.

Added

GCR revenue for the year ended December 31, 2025 decreased by $12.2 million, or 7.0%, to $161.1 million, compared to $173.3 million for the year ended December 31, 2024. The decrease in year-over-year GCR revenue was primarily attributable to the Company’s continued execution of its strategic mix-shift toward ODR work, which resulted in lower GCR organic revenue of $39.9 million. This decline was partially offset by an incremental increase in GCR acquisition-related revenue of approximately $27.7 million from the Pioneer Power, Consolidated Mechanical and Kent Island acquisitions during 2025.

Removed

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

Added

The Company's gross profit for the year ended December 31, 2025 increased by $25.0 million, or 17.4%, to $169.3 million, compared to $144.3 million for the year ended December 31, 2024. The increase was primarily driven by higher gross profit in the ODR segment, partially offset by lower total gross margins.

Added

ODR gross profit increased $22.1 million, or 20.5%, primarily due to an increase in revenue, despite lower segment gross margins of 26.7% versus 31.2% year-over-year. The decrease in ODR gross margin was primarily attributable to the impact of certain acquisitions, which operate at lower gross margin profiles relative to the Company’s organic ODR operations, as well as ODR-related project write-ups recognized in 2024 that did not recur in the current year. Management continues to integrate these acquired operations into the Company’s broader operating model with the objective of improving profitability over time.

Added

GCR gross profit increased $2.9 million, or 8.0%, driven by higher segment gross margins of 24.5% compared to 21.1% year-over-year, despite lower GCR segment revenue. The increase in GCR gross margin reflects the Company’s continued selectivity in pursuing GCR projects.

Added

As a result, total gross profit margin decreased to 26.2% for the year ended December 31, 2025 from 27.8% for the year ended December 31, 2024, primarily due to lower ODR segment margins associated with the inclusion of acquired entities, partially offset by improved GCR segment margins.

Removed

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

Reworded

The Company also recorded revisions in its contract estimates for certain ODR and GCR projects.

Other Income (Expenses) Income

Added

Total other expenses for the year ended December 31, 2025 was approximately $0.8 million as compared to total other income of $1.3 million for the year ended December 31, 2024. The change period-over-period was primarily driven by a $1.3 million increase in interest expense related to greater borrowings under the Company’s revolving credit facility to partially finance the Pioneer Power Transaction, and higher financing costs associated with a larger vehicle fleet period-over-period, as well as a $1.4 million decrease in interest income due to reduced cash and cash equivalent balances period-over-period and lower yields on invested balances. Partially offsetting these changes was a $0.7 million increase in gains associated with the disposition of certain property and equipment as part of the Company’s ongoing asset management and fleet optimization efforts.

Removed

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

The Company’s income tax provision was $9.1$9.6 million and $7.3$9.1 million for the years ended December 31, 20242025 and 2023,2024, respectively, and it had a 22.7%19.7% and 26.1%22.7% effective tax rate over those same periods, respectively. The difference between the U.S. federal statutory tax rate and the Company’s effective tax rate year-over-yearperiod-over-period was primarily due to state income taxes, tax credits, other permanent adjustments and discrete tax items. In particular, the Company’s effective rate for the yearyears ended December 31, 20242025 and 20232024 were materially impacted by “excess tax benefits on stock-based compensation” recognized discretely during the first quarter of each year.year Thisas benefita reducedresult of the effective tax rate by 35.1% and 10.2% for the three months ended March 31, 2024 and 2023 respectively, with the impact varying in prior years.

The Company refers to its estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue it had recognized under such contracts, as “backlog.” Backlog includes unexercised contract options. The Company’s backlog includes projects that have a written award, a letter of intent, a notice to proceed or an agreed uponagreed-upon work order to perform work on mutually accepted terms and conditions. Additionally, the difference between the Company’s backlog and remaining performance obligations is due to the portion of unexercised contract options that are excluded, under certain contract types, from the Company’s remaining performance obligations as these contracts can be canceled for convenience at any time by the Company or the customer without considerable cost incurred by the customer. InWhile additionbacklog provides a measure of work expected to be performed in future periods, it is not necessarily a reliable indicator of future revenue or overall performance of the Company. A substantial portion of the Company’s backlog,contracts, itparticularly haswithin its ODR operations, are short-cycle in nature and may be awarded and substantially completed within a substantialshort amountperiod offollowing contractsaward. withThese projects typically have short lead times that book-and-bill within the same reporting period and rapid burn rates and, as a result, are generally not included in reported backlog.

The Company’s GCR backlog was $140.0$141.8 million and $186.9$140.0 million as of December 31, 20242025 and 2023,2024, respectively. Projects are brought into backlog once the Company has been provided a written confirmation of award and the contract value has been established. At any point in time, the Company has a substantial volume of projects that are specifically identified and advanced in negotiations and/or documentation, however those projects are not booked as backlog until the Company has received written confirmation from the owner or the general contractor / construction manager of their intention to award it the contract and they have directed the Company to begin engineering, designing, incurring construction labor costs or procuring needed equipment and material. The Company’s GCR projects tend to be built over a 12- to 24-month schedule depending upon scope and complexity. Most major projects have a preconstruction planning phase, which may require months of planning before actual construction commences. The Company is occasionally employed to deliver a “fast-track” project, where construction commences as the preconstruction planning work continues. As work on the Company’s projects progress, it increases or decreases backlog to take into account its estimate of the effects of changes in estimated quantities, changes in conditions, change orders and other variations from initially anticipated contract revenue, and the percentage of completion of the Company’s work on the projects. Based on historical trends, the Company currently estimates that 72%77% of its GCR backlog as of December 31, 20242025 will be recognized as revenue during 2025.2026. Additionally, the reduction in GCR backlog has been intentional as the Company looks to focus on higher margin projects than it has done historically, as well as its focus on smaller, higher margin owner direct projects.

The Company is closely monitoring evolving macroeconomic conditions and heightened geopolitical risks. During 2025, economic and trade policy uncertainty increased globally. Rising trade tensions and changes to trade policy (including tariffs), global conflicts, labor disruptions, and evolving regulations can contribute to inflationary pressures, supply chain disruptions, and pricing and lead-time volatility for certain materials and equipment. The Company continues to collaborate with suppliers and subcontractors to mitigate potential shortages and reduce supply and price volatility. The Company anticipates an elevated level of uncertainty with respect to inflation and other macroeconomic trends for the foreseeable future.

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

In addition, the U.S. federal government experienced a lapse in appropriations that resulted in a partial shutdown from October 1, 2025 through November 12, 2025. This government shutdown included delays in the approval and funding of federally sponsored projects, interruptions in the issuance of new contracts, and deferred decision-making by government agencies. The Company experienced impacts to its operations as a result of the shutdown; however, those impacts were not material to its financial position or results of operations for 2025. The Company continues to monitor for any potential near-term effects on project timing, awards, or customer procurement activity.

Except as set forth below, there have been no material changes from the risk factors previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Removed

Our dependence on subcontractors and suppliers, including risks associated with increased supplier and subcontractor consolidation, labor market conditions and cost inflation, could increase costs disrupt project execution, and adversely affect our profitability and cash flows.

Removed

We rely extensively on third-party subcontractors to perform a significant portion of the work on many of our contracts and on third-party suppliers to provide equipment and materials required for project execution. If we are unable to retain qualified subcontractors or suppliers, or if they fail to perform as expected, our ability to execute projects efficiently and profitably could be adversely affected. Although subcontractors and suppliers perform portions of the work, we generally remain contractually responsible to our customers for their performance.

Removed

Our ability to bid on and perform contracts depends, in part, on obtaining commitments from subcontractors and suppliers for labor, materials, and equipment at prices and on terms consistent with our bids. If we are unable to obtain such commitments, or if commitments are withdrawn, delayed, or provided on unfavorable terms, we may be unable to pursue certain projects or may experience reduced margins or losses on awarded contracts. In addition, if subcontractors or suppliers fail to deliver materials, equipment, or services in accordance with agreed terms, we may be required to obtain alternative sources at higher cost or incur delays and other unanticipated expenses.

Removed

The markets in which we source materials, equipment and, in certain instances, subcontracted services, have experienced, and may continue to experience, consolidation. As a result, a smaller number of suppliers and subcontractors may have increased bargaining power, which could enable them to impose less favorable terms, including pricing increases, more restrictive payment terms, reduced flexibility, or limitations on availability, capacity or service levels. Increased concentration among suppliers and subcontractors may also reduce competition, limit our ability to negotiate commercially favorable arrangements, increase our dependence on a narrower group of counterparties, and constrain our ability to secure materials or services on advantageous terms. In certain circumstances, we may be unable to pass through increased costs or less favorable terms to our customers.

Removed

Labor shortages, wage inflation and increased costs for subcontracted services, as well as sustained increases in supplier or subcontractor pricing or changes in payment terms, may increase project costs, reduce profitability and increase working capital requirements. Any disruptions in availability, delays in delivery, failures in performance, or inability to obtain materials or subcontracted services on acceptable terms could impair our ability to execute projects, meet customer expectations or competitively price our services, and could have a material adverse effect on our business, financial condition, results of operations and cash flows.

This increase was partially offset by a $17.5 million decline in revenue from the Company’s organic operations for the six months ended June 30, 2026. The Company expects the timing of project commencements and execution within its existing backlog, together with currently expected future bookings, to support organic revenue growth during the remainder of 2026.

Added

•ODR revenue increased by $28.9 million, or 14.5%, primarily due to the acquisition of Pioneer Power, which contributed approximately $37.5 million in ODR revenue in the current period. The Company’s organic ODR operations decreased approximately $8.6 million.

Added

•GCR revenue increased by $8.1 million, or 10.6% primarily due to an incremental increase in GCR acquisition-related revenue of approximately $17.0 million from the Pioneer Power acquisition. This increase was partially offset by lower GCR organic revenue of $8.9 million.

Added

Gross Profit

Added

•Total gross profit decreased by $8.1 million, or 10.6%, primarily due to lower gross margin percentages in both our ODR and GCR segments. The decrease in segment gross margin percentages was primarily driven by the lower margin profile of Pioneer Power. Pioneer Power continues to perform in line with the Company’s integration expectations and management expects gross margins to improve as 2026 progresses. Operational and pricing improvement initiatives are underway to enhance profitability at Pioneer Power, with the goal of bringing gross margins in line with the Company’s historical average over the next two to three years.

Added

•Gross profit margin was also negatively impacted by lower net project write-ups compared to the prior year period and competition for skilled labor and materials associated with construction activity in data center markets. The Company expects gross profit margins to improve during the remainder of 2026; however, margins are expected to remain below the levels achieved during the comparable periods of 2025.

Added

The Company recorded revisions in its contract estimates for certain ODR and GCR projects; however, the Company did not record any material gross profit write-ups or write-downs that had a net gross profit impact of $1.0 million or more during the six months ended June 30, 2026 and 2025.

Added

Selling, General and Administrative

Added

•SG&A expense increased $3.1 million, or 5.8%, due to $1.3 million of SG&A expenses associated with the Pioneer Power acquisition. Acquisition-related SG&A represents SG&A expenses incurred by an acquired business during the twelve-month period following its respective acquisition date. After such period, the results of acquired businesses are included within the Company’s organic operations, and period-over-period changes are discussed on a combined basis. The increase in organic SG&A expense was approximately $1.8 million, primarily due to a $1.8 million increase in payroll related expenses and a $0.7 million increase in stock-based compensation expense, partially offset by a $0.7 million decrease in professional services related expenses. As a percentage of revenue, SG&A expense decreased to 18.0% from 19.3% in the prior-year period.

Added

Acquisition-Related Retention Expense and Contingent Consideration

Added

Acquisition-related retention and contingent consideration expenses were $0.4 million and $1.2 million for the six months ended June 30, 2026 and 2025, respectively. For the six months ended June 30, 2026, these expenses included approximately $0.2 million of acquisition-related retention expense associated with the Pioneer Power acquisition. In connection with the acquisition, the Company entered into retention agreements with certain key employees of the acquired business. Retention compensation expense is recognized ratably over the requisite service period, which extends through December 2027, and is contingent upon continued employment.

Added

In addition, the Company recognized a $0.2 million increase in the fair value of contingent consideration during the six months ended June 30, 2026, compared to a $1.2 million increase during the six months ended June 30, 2025. Changes in the fair value of contingent consideration represent non-cash expenses and were primarily attributable to updates in the estimated probability of achieving the gross profit targets underlying the related earnout arrangements.

Added

See Note 8 – Fair Value Measurements in the accompanying notes to the Company’s condensed consolidated financial statements for further information on the Company’s earnout arrangements.

Added

Amortization of Intangibles

Added

•Amortization of intangibles decreased period-over-period primarily due to certain finite-lived intangible assets becoming fully amortized. This decrease was partially offset by incremental amortization expense associated with intangible assets recognized in connection with the Pioneer Power acquisition.

Added

See Note 5 – Goodwill and Intangibles in the accompanying notes to the Company’s condensed consolidated financial statements for further information on the Company’s intangible assets.

Added

Other (Expenses) Income

Added

•Interest expense increased $0.4 million in the period-to-period comparison primarily due to higher average borrowings under the Company’s revolving credit facility and increased financing costs associated with a larger vehicle fleet compared to the prior-year period.

Added

•Interest income decreased $0.7 million primarily due to lower average cash and cash equivalent balances and reduced yields on invested balances compared to the prior-year period.

Added

•Gain on disposition of property and equipment decreased $0.4 million primarily due to various gains recognized in both periods, none of which were individually material.

Added

Income Taxes

Added

The Company recorded an income tax benefit of $1.8 million for the six months ended June 30, 2026 compared to an income tax provision of $0.8 million for the six months ended June 30, 2025. The effective tax rate was (24.9)% and 4.2% for the six months ended June 30, 2026 and 2025, respectively. The Company’s effective tax rate differed from the U.S. federal statutory tax rate in each period primarily due to state income taxes, federal tax credits, other permanent adjustments and discrete excess tax benefits related to RSU vestings recognized during the first quarter of each year. See Note 10 – Income Taxes in the accompanying notes to the Company’s condensed consolidated financial statements for additional information.

Reworded

The Company refers to its estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue it had recognized under such contracts, as “backlog.” Backlog includes unexercised contract options. The Company’s backlog includes projects that have a written award, a letter of intent, a notice to proceed or an agreed upon work order to perform work on mutually accepted terms and conditions. Additionally, the difference between the Company’s backlog and remaining performance obligations is due to the portion of unexercised contract options that are excluded, under certain contract types, from the Company’s remaining performance obligations as these contracts can be canceled for convenience at any time by the Company or the customer without considerable cost incurred by the customer. While backlog provides a measure of work expected to be performed in future periods, it is not necessarily a reliable indicator of future revenue or overall performance of the Company. A substantial portion of the Company’s contracts, particularly within its ODR operations, are short-cycle in nature and may be awarded and substantially completed within a short period following award. These projects typically have short lead times and rapid burn rates and, as a result, are generally not included in reported backlog. Consequently, fluctuations in reported backlog may not correlate with changes in overall market demand, revenue generation, or operational performance. Additional information related to the Company’s remaining performance obligations is provided in Note 4 —– Revenue from Contracts with Customers in the accompanying notes to its condensed consolidated financial statements.
