Rhea-AI Filing Summary
Sterling Infrastructure, Inc. outlines a diversified construction and infrastructure business across three segments: E‑Infrastructure, Transportation and Building Solutions, operating mainly in the southern and western U.S.
Backlog was $3.01 billion at December 31, 2025, up from $1.69 billion a year earlier, reflecting strong contracted work, though not all backlog is guaranteed to convert to revenue. The company had approximately 4,400 employees and aggregate market value of non‑affiliate equity of about $6.83 billion based on the June 30, 2025 NASDAQ price.
Sterling completed a major strategic move with the $562 million acquisition of CEC Facilities Group, adding electrical and mechanical capabilities to its E‑Infrastructure segment, and deconsolidated its 50% stake in Road and Highway Builders, which is now accounted for under the equity method. At December 31, 2025, debt under its credit agreement totaled $292.5 million, secured by substantially all assets and subject to financial covenants. The report also details extensive risk factors, including cyclicality in construction markets, reliance on government funding, backlog realization risk, regulatory and environmental exposure, labor availability, and sensitivity to interest rates and material cost inflation.

Item 1. Business
Overview of the Company’s Business
Sterling Infrastructure, Inc. (“Sterling” or “the Company”) operates through a variety of subsidiaries within three segments specializing in E-Infrastructure, Transportation and Building Solutions in the United States, primarily across the Southern, Northeastern, Mid-Atlantic and Rocky Mountain regions and the Pacific Islands. E-Infrastructure Solutions provides advanced, large-scale site development services and mission-critical electrical services for data centers, semiconductor fabrication, manufacturing, distribution centers, warehousing, power generation and more. Transportation Solutions includes infrastructure and rehabilitation projects for highways, roads, bridges, airports, ports, rail and storm drainage systems. Building Solutions includes residential and commercial concrete foundations for single-family and multi-family homes, parking structures, elevated slabs, other concrete work, plumbing services, and surveys for new single-family residential builds. From strategy to operations, we are committed to sustainability by operating responsibly to safeguard and improve society’s quality of life. Caring for our people and our communities, our customers and our investors – that is The Sterling Way.
In this report, unless the context otherwise indicates, “Sterling,” “the Company,” “we,” “our” or “us” means Sterling and its consolidated subsidiaries. In addition, references to “Note” or “Notes” refer to the Notes to the Consolidated Financial Statements, included in Item 8 of Part II of this annual report on Form 10-K, unless indicated otherwise.
Business Strategy
Since 2016, our strategic vision has been based on the following elements and objectives:
| Strategic Elements | Strategic Objectives | |||||||
| Solidifying the base | Risk Reduction | |||||||
| Growing high margin products and services | Bottom-Line Growth | |||||||
| Expansion into adjacent markets | Exceed Peer Performance | |||||||
| Build a Platform for Future Accretive Growth | ||||||||
Solidifying the base—The first element of the transformation of the Company that began in 2016 was a deep evaluation of the risks and opportunities associated with our project portfolio. We continue to work to move the business toward the opportunities that provide the most favorable risk/reward dynamics.
Prior to 2015, the company’s historic base of business was low-bid heavy highway projects within the Transportation Solutions segment; gross margins on these projects during this time were approximately 4%. In 2016, we implemented a strategy to solidify the business by improving risk assessment and bid discipline to significantly reduce the probability of project losses. This strategy has been successful, more than doubling the gross margins of heavy highway projects. In early 2025, we announced the strategic downsizing of our Texas heavy highway business, which is expected to be complete in 2026. This is anticipated to drive further improvement in heavy highway margins.
In recent years, our efforts to solidify the base business have been focused on driving productivity across each of our businesses, developing talent and trades people to support the growth of the company and our industries, and expanding our use of technology across the company to enhance our operations and support growth. Further, we are focused on continual safety enhancements across the organization.
Growing high margin products and services—Across our organization, we are focused on pursuing the most attractive project opportunities from a margin and return perspective. This was a key element of the transformation of the company from 2015 through 2019 and remains a key pillar of our strategy today. The focus in this strategic area is to drive consistent, strong bottom-line growth.
In 2016, we implemented a strategy to shift our Transportation Solutions project mix from low-bid heavy highway projects to alternative delivery heavy highway projects and other higher margin work including airports, commercial, piling and shoring and rail. In 2016, our low-bid heavy highway revenue was approximately 79% of our total revenue, but we have progressively lowered this to 9% as of December 31, 2025.
4
In E-Infrastructure Solutions, we have built a reputation for strong execution across large, multifaceted, time-sensitive projects for mission-critical customers. In our site development business, our ability to consistently provide on-time delivery and schedule assurance to our customers through successful project management and execution has become a key source of competitive differentiation, and a factor in our margin profile. In the electrical and mechanical business, we have a strong track record of delivering high-performance electrical solutions for the most demanding mission-critical clients. Our focus on large, time-sensitive mission-critical projects where our superior capabilities are valued by our customers has been a driver of segment margin expansion over time and remains our focus moving forward.
Expansion into adjacent markets—In 2016, we implemented a strategy to pursue growth through the acquisition of companies and assets that will enable us to expand into adjacent markets and broaden the types of projects we execute. We operate a decentralized, adaptive business model, which provides us with flexibility to pursue acquisitions and other strategic transactions. Our acquisition strategy focuses on businesses that can enhance our suite of products and services, expand our geographic footprint or customer relationships, or provide diversification of cash flows. Since 2016, we have completed eleven acquisitions and regularly assess other strategic opportunities. Further, we remain focused on opportunities to expand organically into new markets.
Recent Strategic Transactions
RHB Deconsolidation—Since 2012, the Company has held a 50% ownership interest in Road and Highway Builders, LLC (“RHB”), with Rich Buenting holding the remaining 50% ownership interest. Historically, the Company fully consolidated the entity as a result of its exercise of control of the entity. On December 31, 2024, the parties executed an amendment to the RHB operating agreement to ensure the continuation of this mutually beneficial relationship while addressing the evolving needs and interest of both parties.
Under GAAP, this contractual change required Sterling to no longer consolidate RHB’s results with its own and to use equity method accounting with respect to Sterling’s interest in the entity. Beginning January 1, 2025, the Company reports its portion of RHB’s income as a single line item (“Other operating income (expense), net”) in the Consolidated Statements of Operations and reports its interest in RHB at December 31, 2024 and thereafter, as a single line item (“Investment in unconsolidated subsidiary”) in the Consolidated Balance Sheets. RHB’s revenue is no longer included in Sterling’s consolidated revenue in 2025 and Sterling’s consolidated backlog figures as of December 31, 2024 and thereafter, do not include RHB’s backlog.
CEC Acquisition—On September 1, 2025, the Company acquired substantially all of the assets of Irving, Texas-based CEC Facilities Group, LLC (“CEC”) a leading specialty electrical and mechanical contractor. The purchase price was $562 million, consisting primarily of $443 million in cash and $79 million in common stock. Additionally, CEC has an earn-out opportunity of up to an aggregate of $80 million, contingent upon achieving certain operating income targets. CEC is included in the Company’s E-Infrastructure Solutions segment.
Segments, Markets and Customers
The Company’s internal and public segment reporting are aligned based upon the services offered by its operating groups, which represent the reportable segments. The Company’s operations consist of three reportable segments: E-Infrastructure Solutions, Transportation Solutions and Building Solutions. See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 20 - Segment Information for further discussion of our business segments.
E-Infrastructure Solutions—Our E-Infrastructure Solutions segment serves large, blue-chip end users in the data center, manufacturing, e-commerce distribution center, warehousing, power generation sectors and more. We are a leading provider of large-scale site development services in the Southeast, Northeast, Mid-Atlantic and Rocky Mountain regions of the United States. The top four customers in each year, accounted for 27% of the segment’s revenue in 2025, 31% in 2024 and 40% in 2023.
Transportation Solutions—Our Transportation Solutions segment is comprised of heavy highway, aviation and rail projects, and it relies heavily on federal and state infrastructure spending. The principal geographic markets of this segment are Utah, Arizona, Colorado, Nevada, Texas and the Pacific Islands. Within these principal markets, our core customers are state Departments of Transportation (“DOT(s)”) and regional transit, airport, port, water and railroad authorities. The top four state DOTs in each year, accounted for 58% of the segment’s revenue in 2025, 47% in 2024 and 50% in 2023.
5
Building Solutions—Our Building Solutions segment is comprised of our residential and commercial businesses. The principal geographic market for our residential business is Texas, specifically Dallas-Fort Worth, Houston and the surrounding communities. In 2021, we expanded our residential business into the greater Phoenix area and continued this expansion in 2022 with the acquisition of the CCS business. In 2023, we further expanded our services in the Dallas-Fort Worth market to include plumbing services for all the major plumbing phases required for new single-family residential builds with our acquisition of PPG. Our core residential customer base is comprised of leading national, regional and custom home builders. Our commercial business focuses on concrete construction of multi-family foundations, parking structures, elevated slabs and other concrete work for leading developers and general contractors in commercial markets. The top four customers in each year, including their respective affiliates, accounted for 45% of the segment’s revenue in 2025, 36% in 2024 and 42% in 2023.
In 2025, no individual customer accounted for more than 10% of our consolidated revenues; however we routinely construct projects for our largest customers mentioned above. The loss of any of these customers could have a material adverse effect on our business and financial results. Refer to Item 1A “Risk Factors” and Note 18 - Concentration of Risk and Enterprise Wide Disclosures for information on the Company’s major customers that represent a concentration of risk due to their significant revenue contributions.
Competition
The competitors of our segments vary widely, from small local contractors to large international construction companies. We aim to position ourselves in the mid-level market, traditionally bidding on work too large for the small local contractors yet too small for the large national and international construction companies. However, should market conditions become less favorable, we would expect to see a convergence from both the small local contractors and large international construction companies into our targeted mid-level market. This convergence could increase competitive bidding pressure and reduce both revenue growth and margins. See Item 1A “Risk Factors” for further discussion of risks associated with our competitive environment.
Seasonality
Operations of our segments are often affected by weather conditions, especially during the first and fourth quarters of our fiscal year. These conditions may disrupt construction schedules and lead to variability in our revenues, profitability and the number of employees we require. For additional discussion regarding the potential impacts of seasonality on our business, see Item 1A “Risk Factors.”
Resources
We procure raw materials essential for the operation of our segments, such as, cement, aggregate, concrete, liquid asphalt, lumber, steel and fuels, including diesel, gasoline, natural gas and propane, from a broad network of sources. Fluctuations in the price and availability of these raw materials may vary over time due to changes in market conditions and production capacities.
Backlog
Our remaining performance obligations on our projects, as defined in Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers, do not differ from what we refer to as “Backlog.” Our Backlog represents the amount of revenues we expect to recognize in the future from our contract commitments on projects. The contracts in Backlog are typically completed in 6 to 36 months. The value of our Backlog was $3.01 billion at December 31, 2025, as compared to $1.69 billion at December 31, 2024. We exclude from our Backlog any contract where we are the apparent low bidder for projects (“Unsigned Awards”) until such contract is formally executed by the customer (approximately $300.7 million at December 31, 2025). Certain Building Solutions revenue is recognized upon completion at a point in time and therefore is never reflected in our Backlog. See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Backlog” for a discussion and quantification of our Backlog. Also see Item 1A “Risk Factors” for further discussion of risks related to Backlog.
Contracts
Our contracts are awarded on a competitively bid basis or negotiated bid basis using a range of contracting options, including fixed-unit price, lump sum and cost-reimbursable. Each of these contract types presents advantages and disadvantages. Typically, the Company assumes more risk with lump-sum contracts; however, these types of contracts can yield additional profits if the work is completed for less than originally estimated. Under fixed-unit price contracts, the Company’s profit may vary if actual labor-hour costs vary significantly from the negotiated rates. Each contract is designed to optimize the balance between risk and reward. At December 31, 2025, substantially all of our Backlog was contracted on a fixed-unit price or lump sum basis. We occasionally present claims or change orders to our clients for additional costs
6
exceeding or not included in the initial contract price. Also, because some contracts can provide little or no fee for managing material costs, the components of contract cost can impact profitability.
Substantially all of the contracts in our Backlog contain termination for convenience clauses which allow the customer to cancel the contract at their election but would require that the Company be compensated for work performed through the date of termination and for any applicable contractual costs for cancellation. As part of our business, we are a party to joint venture arrangements, pursuant to which we typically jointly bid on and execute particular projects with other companies in the construction industry. See Item 1A “Risk Factors” and Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a discussion of our types of risk and how we mitigate cancellation and credit risk.
Insurance and Bonding
Our buildings and equipment are covered by insurance at levels our management believes to be adequate. In addition, we maintain general liability, excess liability, workers’ compensation and auto insurance all in amounts deemed consistent with our risk of loss and standard industry practice.
As a normal part of the Transportation Solutions business and occasionally with the E-Infrastructure Solutions business, we are required to provide various types of surety and payment bonds that provide an additional measure of security for our performance under the contract. Primarily for Transportation Solutions, a bidder for a contract must post a bid bond, generally for 5% to 10% of the bid amount, and upon being awarded the bid, must post a performance and payment bond for up to 100% of the costs to construct. Additionally, we may also be required to post a maintenance bond for generally 1% of the contract amount for one to two years. Our ability to obtain bonds depends upon our capitalization, working capital, aggregate contract size, past performance, management expertise and external factors, including the capacity of the overall surety market. Bonding companies consider such factors in light of the amount of our Backlog that we have currently bonded and their current underwriting standards, which may change from time to time. As is customary, we have agreed to indemnify our bonding company for all losses incurred by it in connection with bonds that are issued, and we have granted our bonding company a security interest in certain assets, including accounts receivable, as collateral for such obligation.
Government and Environmental Regulations
Our operations must comply with various regulatory requirements imposed by federal, state and local agencies and authorities, including safety, wage and hour regulations and other labor issues, immigration controls, vehicle and equipment operations and other aspects of our business. For example, our operations are subject to the requirements of the Occupational Safety and Health Act (“OSHA”) and comparable state laws directed toward the protection of employees. In addition, most of our Transportation Solutions construction contracts are entered into with public authorities, and these contracts frequently impose additional governmental requirements, including requirements regarding labor relations and subcontracting with designated classes of disadvantaged businesses.
All of our operations are also subject to federal, state and local laws and regulations relating to the environment, including those relating to discharges into air, water and land, climate change, the handling and disposal of solid and hazardous waste, the handling of underground storage tanks and the cleanup of properties affected by hazardous substances. For example, we must apply water or chemicals to reduce dust on road construction projects and to contain contaminants in storm run-off water at construction sites. In certain circumstances, we may also be required to hire subcontractors to dispose of hazardous wastes encountered on a project in accordance with a plan approved in advance by the customer. Certain environmental laws impose substantial penalties for non-compliance and others, such as the federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) impose strict and retroactive joint and several liability upon persons responsible for releases of hazardous substances.
CERCLA and comparable state laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons that contributed to the release of a “hazardous substance” into the environment. These persons include the owner or operator of the site where the release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the site. Under CERCLA, these persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. CERCLA also authorizes the federal Environmental Protection Agency (“EPA”) and, in some instances, third parties, to act in response to threats to the public health or the environment and to seek to recover from the responsible classes of persons the costs they incur.
7
Solid wastes, which may include hazardous wastes, are subject to the requirements of the federal Solid Waste Disposal Act, the federal Resource Conservation and Recovery Act (“RCRA”) and comparable state statutes. Although we do not generate solid waste, we occasionally dispose of solid waste on behalf of our customers. From time to time, the EPA considers the adoption of stricter disposal standards for non-hazardous wastes. Moreover, it is possible that additional wastes will in the future be designated as “hazardous wastes.” Hazardous wastes are subject to more rigorous and costly disposal requirements than are non-hazardous wastes, and any future “hazardous wastes” designations of the solid waste we dispose on behalf of our customers could adversely affect our business, financial condition and results of operations.
We continually evaluate whether we must take additional steps at our locations to ensure compliance with environmental laws. While compliance with applicable regulatory requirements has not materially adversely affected our operations in the past, there can be no assurance these requirements will not change and compliance will not adversely affect our operations in the future. In addition, tighter regulation for the protection of the environment and other factors may make it more difficult to obtain new permits and renewal of existing permits may be subject to more restrictive conditions than currently exist.
Human Capital
At December 31, 2025, the Company had approximately 4,400 employees, comprised of approximately 1,200 salaried employees and approximately 3,200 hourly employees. The percentage of our employees represented by unions at December 31, 2025 was approximately 4%. We maintain agreements with various unions representing groups of our employees at project sites, and we typically renew these agreements periodically. We consider our relationships with our employees and the applicable labor unions to be satisfactory.
Our business is dependent upon a readily available supply of management, supervisory and field personnel. Substantially all of our employees are hired on a full-time basis; however, as is typical in the construction industry, we experience a high degree of turnover as construction projects are completed. In the past, we have been able to attract a sufficient number of personnel to support the growth of our operations; however, we continue to face competition for experienced workers in all of our markets, and we cannot guarantee we will continue to attract a sufficient number of personnel.
Our employees are important to the success of our business. Hiring, developing and retaining our employees is not only important, but is a necessity for continued growth and delivery at all levels within our organization. Every employee is critical to our organization’s success, and we are dedicated to ensuring that we manage our workforce’s needs and requirements. We often work in tight labor markets that make hiring and retaining employees challenging. Therefore, it is critical to have a strategic plan for hiring and managing our workforce. We develop hiring practices by geographic area to ensure a customizable recruiting strategy that allows all of our businesses to thrive. Retaining our employees through various means of succession planning and other retention tools is also a critical component of our strategy, particularly for our key positions. Planning for today as well as the future is the cornerstone of our people strategy. We strive to instill an inclusive culture that provides all our employees the opportunity to thrive.
We focus on our safety processes, which have allowed us to maintain a high level of safety at our work sites. All project employees receive hazard specific training and our newly-hired employees undergo an initial safety orientation and receive follow-up trainings during their first 90 days of employment. Our project managers and superintendents work closely with our safety department to ensure safety is planned into all of our operations before they begin. Additionally, our project foremen are required to conduct daily safety briefings with our employees. Regular safety walkthroughs are conducted by our managers, supervisors and safety staff to evaluate project conditions and observe employee safety behavior.

Item 1A. Risk Factors
The following discussion of risk factors contains forward-looking statements. These risk factors may be important to understanding other statements in this annual report on Form 10-K. The following information should be read in conjunction with Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the Consolidated Financial Statements and related Notes in Part II, Item 8 “Financial Statements and Supplementary Data” of this annual report on Form 10-K.
Our business, financial condition and operating results can be affected by a number of factors, whether currently known or unknown, including but not limited to those described below; any one or more of which could, directly or indirectly, cause our actual financial condition and operating results to vary materially from our past, or from our anticipated future, financial condition and operating results. Any of these factors, including additional factors that apply to all companies generally which are not specifically mentioned below, in whole or in part, could materially and adversely affect our business, prospects, financial condition, results of operations, stock price and cash flows.
Because of the following factors, as well as other factors affecting our financial condition and operating results, our past financial performance should not be considered to be a reliable indicator of our future performance, and investors should not use historical trends to anticipate results or trends in future periods.
Risks Related to Our Business and Industry
Demand for our services may decrease during economic recessions or volatile economic cycles, and a reduction in demand in end markets may adversely affect our business.
Across our three operating segments, revenue and profit are generated from infrastructure projects and services, but we do not directly control the process by which such infrastructure projects and services are awarded. The construction industry historically has experienced cyclical fluctuations in financial results due to economic recessions, downturns in business cycles of our customers, supply chain disruptions and the price or availability of building materials, inflationary pressures, interest rate fluctuations, international trade issues, including tariffs and counter tariffs, and other economic factors beyond our control. Many factors, including the financial condition of the infrastructure industry, could adversely affect our customers and their willingness to fund capital expenditures in the future. Additionally, consolidation, competition or capital constraints in the industries we serve may result in reduced spending by our customers.
Economic, regulatory and market conditions affecting our specific end markets may adversely impact the demand for our services, resulting in the delay, reduction or cancellation of certain projects and these conditions may continue to adversely affect us in the future.
Our dependence on suppliers of materials and subcontractors could increase our costs and impair our ability to complete contracts on a timely basis or at all.
The price and availability of the materials required to execute our projects are subject to volatility and disruptions caused by global economic factors that are beyond our control, including, but not limited to, labor shortages, wage pressures, rising inflation and potential economic slowdown or recession, as well as fuel and energy costs, the impact of natural disasters, geopolitical conflicts (such as the conflicts in Eastern Europe and the Middle East), and other matters that have impacted or could impact the global economy. If shortages and cost increases in materials and tightness in the labor market persist for a prolonged period of time, and we are unable to offset such cost increases, our profit margins could be adversely impacted.
We rely on third party suppliers to provide substantially all of the materials for our contracts and third party subcontractors to perform some of the work on many of our projects. For the past several years, our operating margins have been adversely impacted, and may continue to be impacted, by price increases for certain construction materials, as well as fuel for our equipment. To the extent that we are unable to obtain commitments from our suppliers for materials or engage subcontractors, our ability to bid for contracts may be impaired.
If we do not accurately estimate the overall risks, requirements or costs related to a project when we bid for a contract that is ultimately awarded to us, we may achieve a lower than anticipated profit or incur a loss on the contract.
The majority of our revenues and backlog are derived from fixed-unit price contracts and lump sum contracts. Fixed-unit price contracts require us to provide materials and services at a fixed-unit price based on agreed quantities irrespective of our actual per unit costs. Lump sum contracts require the contract work to be completed for a single price irrespective of our actual costs incurred. Our ability to achieve profitability under such contracts is dependent upon our ability to avoid cost overruns by accurately estimating our costs and then successfully controlling our actual costs. If our cost estimates for a contract are inaccurate, or if we do not perform the contract within our cost estimates, we may incur losses due to cost overruns or the
9
contract may be less profitable than expected. As a result, these types of contracts could negatively affect our cash flow, earnings and financial position.
The costs incurred and gross profit realized on our contracts can vary, sometimes substantially, from our original estimates due to a variety of factors, that may include, but are not limited to the following:
•onsite conditions that differ from those assumed in the original bid or contract;
•failure to include required materials or work in a bid, or the failure to estimate properly the quantities or costs needed to complete a lump sum contract;
•delays caused by weather conditions;
•contract or project modifications creating unanticipated costs not covered by change orders or contract price adjustments;
•changes in availability and proximity of construction materials, as well as fuel for our equipment; and
•claims or demands from third parties for alleged damages arising from the design, construction or use and operation of a project of which our work is a part.
Many of our contracts with public sector customers 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. Public sector customers may seek to impose contractual risk-shifting provisions more aggressively, which could increase risks and adversely affect our cash flow, earnings and financial position.
Further, in most cases, our contracts require completion by a scheduled acceptance date. Failure to timely complete a project could result in additional costs, penalties or liquidated damages being assessed against us, and these could exceed projected profit margins on the contract.
We may incur higher costs to lease, acquire and maintain equipment necessary for our operations, and the market value of our owned equipment may decline.
We service a significant portion of our contracts with our own construction equipment rather than leased or rented equipment. To the extent that we are unable to buy construction equipment necessary for our needs, either due to a lack of available funding or equipment shortages in the marketplace, we may be forced to rent equipment on a short-term basis, which could increase the costs of performing our contracts, thereby reducing contract profitability. Further, new equipment may not be available, or it may not be purchased or rented in a cost effective manner, which could adversely affect our operating results.
The equipment that we own or lease requires continuous maintenance, for which we maintain our own repair facilities. If we are unable to maintain or repair equipment ourselves, we may be forced to obtain third party repair services, which could increase our costs. Additionally, we rely on the availability of component parts from suppliers for the maintenance and repair of our equipment. The failure of suppliers to deliver component parts necessary to maintain our equipment could have an adverse effect on our ability to meet our commitments to customers.
We may not accurately assess and/or estimate the quality, quantity, availability and cost of aggregates we need to complete a project, particularly for projects in rural areas.
Particularly for projects in rural areas, we may estimate the quality, quantity, availability and cost for aggregates (such as sand, gravel, crushed stone, slag and recycled concrete) from sources that we have not previously used as suppliers, which increases the risk that our estimates may be inaccurate. Inaccuracies in our estimates regarding aggregates could result in significantly higher costs to supply aggregates needed for our projects, as well as potential delays and other inefficiencies. If we fail to accurately assess the quality, quantity, availability and cost of aggregates, it could cause us to incur losses, which could materially adversely affect our results of operations.
Timing of the award and performance of new contracts may fluctuate.
It is generally very difficult to predict whether and when new contracts will be offered for tender, as our contracts frequently involve a lengthy and complex design and bidding process, which is affected by a number of factors, such as market conditions, funding arrangements and governmental approvals. Because of these factors, our results of operations and cash flows may fluctuate from quarter to quarter and year to year, and the fluctuation may be substantial.
The uncertainty of the timing of contract awards may also present difficulties in matching the size of our equipment fleet and work crews with contract needs. In some cases, we may maintain and bear the cost of more equipment and ready work crews than are necessary for then-existing needs, in anticipation of future needs for existing contracts or expected future
10
contracts. If a contract is delayed or an expected contract award is not received, we would incur costs that could have a material adverse effect on our anticipated profit.
Adverse weather conditions may cause delays, which could slow completion of our construction activity.
Because a significant portion of our construction projects are performed outdoors, work on those contracts is subject to seasonal weather conditions that may delay our work and contribute to project inefficiency. Lengthy periods of wet or cold winter weather will generally interrupt construction, and this can lead to under-utilization of crews and equipment, resulting in less efficient rates of overhead recovery. Extreme heat or cold can prevent us from performing certain types of operations. For example, during the late fall to the early spring months of each year, our work on construction projects in the Rocky Mountain States has been curtailed at times due to snow and other work-limiting weather. In addition, our work is subject to extreme and unpredictable weather conditions, which could become more frequent or severe if general climatic changes occur. For example, in 2021 there was a Texas-wide freezing weather event that caused delays for some of our Transportation Solutions and Building Solutions operations. While revenues can be recovered following a period of bad weather, it is generally impossible to recover the cost of inefficiencies, and significant periods of bad weather typically reduce profitability of affected contracts both in the current period and during the future life of affected contracts. Such reductions in contract profitability negatively affect our results of operations in current and future periods until the affected contracts are completed. To the extent climate change results in an increase in such extreme adverse weather conditions, the likelihood of a negative impact on our operations may increase.
We rely on information technology systems to conduct our business, which are subject to disruption, failure or security breaches.
We rely on information technology (“IT”) systems in order to achieve our business objectives. We also rely upon industry accepted security measures and technology to securely maintain confidential information on our IT systems. However, our portfolio of hardware and software products, solutions and services and our enterprise IT systems may be vulnerable to damage or disruption caused by circumstances such as catastrophic events, power outages, computer system or network failures, computer viruses, cyber-attacks or other malicious software programs. The failure or disruption of our IT systems to perform as anticipated for any reason could disrupt our business and result in decreased performance, significant remediation costs, transaction errors, loss of data, processing inefficiencies, downtime, litigation and the loss of suppliers or customers. A significant disruption or failure could have a material adverse effect on our business operations, financial performance and financial condition.
Major public health crises could disrupt our operations and adversely affect our business, results of operations and financial condition.
Pandemics, epidemics, widespread illness, or other public health crises that interfere with the ability of our employees, suppliers, customers, financing sources or others to conduct business have and could adversely affect the global economy and our results of operations and financial condition. For example, our business and results of operations could be materially adversely affected if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, or government actions or other restrictions in connection with any future major public health crisis.
Risks Related to Our Segments
E-Infrastructure Solutions
Our E-Infrastructure Solutions business, as well as the industries of many of our customers upon whom we are dependent, are susceptible to economic downturns, including periods of slower than anticipated economic growth.
Demand for our E-Infrastructure Solutions business is cyclical and may be vulnerable to economic downturns, market interest rate fluctuations or other adverse developments in the credit markets, and reductions in private industry spending; the effects of which may cause our customers to delay, curtail or cancel proposed and existing projects. A number of factors can adversely affect the industries we serve, including, among other things, financing or credit availability, potential bankruptcies, global and U.S. trade relationships or other geopolitical events. A reduction in cash flow or the lack of availability of debt or equity financing for our customers could cause our customers to reduce their spending for our services or affect the ability of our customers to pay amounts owed to us.
11
Transportation Solutions
The heavy highway construction industry is highly competitive, with a variety of companies competing against us, and our failure to compete effectively could reduce the number of new contracts awarded to us or adversely affect our margins on contracts awarded.
In the past, many of the heavy highway contracts on which we bid were awarded through a competitive bid process, with awards generally being made to the lowest bidder, but sometimes recognizing other considerations, such as shorter contract schedules or prior experience with the customer and reputation. Within our geographic markets, we compete with many international, national, regional and local construction firms. Several of these competitors have achieved greater geographic market penetration than we have in the geographic markets in which we compete, and/or have greater resources, including financial resources, than we do. In addition, a number of international and national companies in the heavy highway construction industry that are larger than we are and that currently do not have a significant presence in our geographic markets, if they so desire, could establish a presence in our geographic markets and compete with us for contracts.
In addition, if the use of design-build, construction manager/general contractor (CM/GC) and other alternative project delivery methods continues to increase and we are not able to further develop our capabilities and reputation in connection with these alternative delivery methods, we will be at a competitive disadvantage, which may have a material adverse effect on our financial position, results of operations, cash flows and prospects. If we are unable to compete successfully in our markets, our relative market share and profits could also be reduced.
Our Transportation Solutions business relies on highly competitive and highly regulated state or local government contracts.
State and local government funding for public works projects is limited, thus creating a highly competitive environment for the limited number of public projects available. In addition, state and local government contracts are subject to specific procurement regulations, contract provisions and a variety of regulatory requirements relating to their formation, administration, performance and accounting. Many of these contracts include express or implied certifications of compliance with applicable laws and contract provisions. As a result, any violations of these regulations could bring about litigation and could cause termination of other existing state or local government contracts and result in the loss of future state or local government contracts. Due to the significant competition in the marketplace and the level of regulations on state or local government contracts, we could suffer reductions in new projects and see lower revenues and profit margins on those projects, which could have a material adverse effect on the business, operating results and financial condition.
Our Transportation Solutions business depends on our ability to qualify as an eligible bidder under state or local government contract criteria and to compete successfully against other qualified bidders in order to obtain state or local government contracts.
State and local government agencies conduct rigorous competitive processes for awarding many contracts. Some contracts include multiple award task order contracts in which several contractors are selected as eligible bidders for future work. We will potentially face strong competition and pricing pressures for any additional Transportation Solutions contract awards from other government agencies, and we may be required to qualify or continue to qualify under various multiple award task order contract criteria. Our inability to qualify as an eligible bidder under state or local government contract criteria could preclude us from competing for certain other government contract awards. In addition, our inability to qualify as an eligible bidder, or to compete successfully when bidding for certain state or local government contracts and to win those Transportation Solutions contracts, could materially adversely affect our business, operations, revenues and profits.
The design-build project delivery method subjects our Transportation Solutions business to the risk of design errors and omissions.
We could be liable for a design error or omission that causes or contributes to damages with respect to one of our Transportation Solutions design-build projects. Although by contract we pass design responsibility on to the engineering firms that we engage to perform design services on our behalf for these projects, in the event of a design error or omission causing damages, there is risk that the engineering firm, its professional liability insurance, and the errors and omissions insurance that we individually purchase will not fully protect us from costs or liabilities. Any liabilities resulting from an asserted design defect with respect to our Transportation Solutions projects may have a material adverse effect on our financial position, results of operations and cash flows. Performance problems on existing and future Transportation Solutions contracts could cause actual results of operations to differ materially from those anticipated by us and could cause us to suffer damage to our reputation within the infrastructure industry and among our customers.
12
An inability to obtain bonding could limit the aggregate dollar amount of contracts that we are able to pursue for our Transportation Solutions business.
As is customary in the construction business, we are required to provide bonding to our Transportation Solutions customers to secure our performance under our contracts. Our ability to obtain bonding primarily depends upon our capitalization, working capital, borrowing capacity under our credit facilities, past performance, management expertise and reputation and certain external factors, including the overall capacity of the credit market. Bonding companies and banks consider such factors in relationship to the amount of our backlog and their underwriting standards, which may change from time to time. Events that adversely affect the financial markets generally may result in bonding becoming more difficult to obtain in the future, or being available only at a significantly greater cost. Our inability to obtain adequate bonding would limit the amount that we can bid on new contracts for our Transportation Solutions business and could have a material adverse effect on our future revenues and business prospects.
Our Transportation Solutions business is susceptible to economic downturns and reductions in state or local government funding of infrastructure projects.
Our Transportation Solutions business is highly dependent on the amount and timing of infrastructure work funded by various governmental entities, which, in turn, depend on the overall condition of the economy, the need for new or replacement infrastructure, the priorities placed on various projects funded by governmental entities and federal, state or local government spending levels. Spending on infrastructure could decline for numerous reasons, including decreased revenues received by state and local governments for spending on such projects. For example, state spending on highway and other projects can be adversely affected by decreases or delays in, or uncertainties regarding, federal highway funding, which could adversely affect us since we are reliant upon contracts with state transportation departments for a significant portion of our revenues.
Refer to our “Business—Segments, Markets and Customers” section within Item 1 for a more detailed discussion of our geographic markets, and refer to Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Market Outlook and Trends” for a discussion of our current expectations regarding federal spending.
A prolonged government shutdown may adversely affect our Transportation Solutions business.
We derive a significant portion of our Transportation Solutions revenue from governmental agencies and programs. A prolonged government shutdown could impact inspections, regulatory review and certifications, grants, approvals, or cause other situations that could result in our incurring substantial labor or other costs without reimbursement under government contracts, or the delay or cancellation of key government programs in which we are involved, all of which could have a material adverse effect on our business and results of operations.
Building Solutions
The homebuilding industry is cyclical and susceptible to downward changes in general economic or other business conditions which could adversely affect our Building Solutions projects, including foundations and plumbing for single-family and multi-family homes.
Our Building Solutions business is sensitive to changes in economic conditions and other factors, such as the level of employment, consumer confidence, consumer income, availability of financing and interest rate levels. Beginning in 2022, rising inflation and increased interest rates made home ownership less affordable, which resulted in decreased demand for single-family homes. Should these conditions, especially in the markets where we operate, continue or worsen, new home demand and prices could suffer and customers might cancel pending contracts. This impact could adversely affect the number of Building Solution projects we have or reduce the prices we can charge for these projects, either of which could result in a decrease in our revenues and earnings that could materially adversely affect our results of operations.
We cannot predict with certainty whether the decline in the U.S. housing market will continue or worsen due to changes in conditions that are beyond our control, which may include the following:
•interest rate uncertainty;
•shortage of lots available for development; and
•changes in demographics and population migration that impair the demand for new housing.
13
Risks Related to Our Construction Joint Venture Partners and Customers
Our participation in construction joint ventures exposes us to liability and/or harm to our reputation for failures of our partners.
As part of our business, we are a party to construction joint venture arrangements, pursuant to which we typically jointly bid on and execute particular projects with other companies in the construction industry. Success on these construction joint projects depends in part on whether our joint venture partners satisfy their contractual obligations.
We and our construction joint venture partners are generally jointly and severally liable for all liabilities and obligations of our construction joint ventures. If a construction joint venture partner fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming from lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate share of a liability to make up for our partner’s shortfall. Furthermore, if we are unable to adequately address our partner’s performance issues, the customer may terminate the project, which could result in legal liability to us, harm to our reputation and reduce our profit on a project.
Certain counterparties to construction joint venture arrangements, which may include our historical direct competitors, may not desire to continue such arrangements with us and may terminate the joint venture arrangements or not enter into new arrangements following a merger or acquisition. Any termination of a construction joint venture arrangement could cause us to reduce our backlog and could materially and adversely affect our business, results of operations and financial condition.
At December 31, 2025, there was approximately $371.9 million of construction work to be completed on unconsolidated construction joint venture contracts, of which $148.8 million represented our proportionate share. We are not aware of any situation that would require us to fulfill responsibilities of our construction joint venture partners pursuant to the joint and several liability under our contracts.
We may not be able to recover on claims or change orders against clients for payment or on claims against subcontractors for performance.
We occasionally present claims or change orders to our clients for additional costs exceeding a contract price or for costs not included in the original contract price. Change orders are modifications of an original contract that effectively change the provisions of the contract without adding new provisions. They generally include changes in specifications or design, facilities, equipment, materials, sites and periods for completion of work. Claims are amounts in excess of the agreed contract price (or amounts not included in the original contract price) that we seek to collect for customer-caused delays, errors in specifications and designs, contract terminations or other causes of unanticipated additional costs. These costs may or may not be recovered until the claim is resolved. In addition, we may have claims against subcontractors for performance or non-performance related issues that resulted in additional costs on a project. In some instances, these claims can be the subject of lengthy legal proceedings, and it is difficult to accurately predict when they will be fully resolved. A failure to promptly document and negotiate a recovery for change orders and claims could have a negative impact on our cash flows and overall ability to recover change orders and claims, which would have a negative impact on our financial condition, results of operations and cash flows.
We are dependent on a limited number of significant customers.
Due to the size and nature of our contracts, one or a few customers have in the past and may in the future represent a substantial portion of our consolidated revenues and gross profits in any one year or over a period of several consecutive years. Similarly, our backlog frequently reflects multiple contracts for certain customers; therefore, one customer may comprise a significant percentage of backlog at a certain point in time. We are unable to predict whether a customer will have a significant downturn in their business or financial condition. The loss of business or a default or delay in payment from any one of these customers could have a material adverse effect on our business, results of operations, cash flows and financial condition.
The early termination of contracts and uncertainty of new project awards could adversely affect our business.
Our contracts generally have clauses that permit the cancellation of the contract unilaterally and at any time as long as the customer compensates us for the work already completed and for additional contractual costs for cancellation. A cancellation of an unfinished contract could cause our equipment and work crews to be idle for a period of time until other comparable work becomes available. Additionally, we may be prohibited from bidding on certain government contracts if we fail to maintain required qualifications, and the timing of project awards is unpredictable and outside of our control due to complex and lengthy negotiation processes. Any of the foregoing could have a material adverse effect on our results of operations and financial condition.
14
Risks Related to Our Workforce
Our business depends on our ability to attract and retain talented employees.
Our ability to attract and retain reliable, qualified personnel is a significant factor that enables us to successfully bid for and profitably complete our work. This includes management, project managers, estimators, supervisors, foremen, equipment operators and laborers for each of our subsidiaries. The loss of the services of any of our subsidiaries’ management-level personnel could have a material adverse effect on us. Our future success will also depend on our ability to hire and retain, or to attract when needed, highly-skilled personnel. Effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution.
We may be subject to unionization, work stoppages, slowdowns or increased labor costs.
In several of the states in which we operate, we have project personnel that are unionized. Additional groups of our employees may also unionize in the future. If at any time a significant amount of our employees unionized, it could limit the flexibility of the workforce and could result in demands that might increase our operating expenses and adversely affect our profitability. Our inability to negotiate acceptable contracts with unions could result in work stoppages, and any new or extended contracts could result in increased operating costs. In addition, we may be subject to disruptions by organized labor groups protesting our non-union status. The future or continued occurrence of any of these events would be disruptive to our operations and could have a material adverse effect on our business, operating results and financial condition.
If we are unable to comply with applicable immigration laws, our ability to successfully complete contracts may be negatively impacted.
We rely heavily on immigrant labor. We have taken steps that we believe are sufficient and appropriate to ensure compliance with immigration laws. However, we cannot provide assurance that we have identified, or will identify in the future, all undocumented immigrants who work for us. Our failure to identify undocumented immigrants who work for us may result in fines or other penalties being imposed upon us, which could have a material adverse effect on our results of operations and financial condition. Immigration laws have also been an area of considerable political focus in recent years, and, from time-to-time, the U.S. government considers or implements changes to federal immigration laws, regulations or enforcement programs. Changes in immigration or work authorization laws may increase our obligations for compliance and oversight, which could subject us to additional costs and potential liability and make our hiring processes more cumbersome, or reduce the availability of potential employees. Any of the foregoing could have a material adverse effect on our results of operations and financial condition.
Our operations are subject to hazards that may cause personal injury or property damage, thereby subjecting us to liabilities and possible losses, which may not be covered by insurance as well as negative reputational impacts relating to health and safety matters.
Our workers are subject to hazards associated with providing construction and related services. These operating hazards can cause personal injury, loss of life, damage to or destruction of property, plant and equipment or environmental damage. On most sites, we are responsible for safety and are contractually obligated to implement safety procedures. Our safety record is an important consideration for us and for our customers. If we experience a material increase in the frequency or severity of accidents, our safety record could substantially deteriorate, which may preclude us from bidding on certain work, expose us to potential lawsuits or cause customers to cancel existing contracts.
We maintain general liability and excess liability insurance, workers’ compensation insurance, auto insurance and other types of insurance all in amounts consistent with our risk of loss and infrastructure industry practice, but this insurance may not be adequate to cover all losses or liabilities that we may incur in our operations. Insurance liabilities are difficult to assess and quantify due to unknown factors, including the severity of an injury, the number of incidents not reported and the effectiveness of our safety program. If we were to experience insurance claims or costs above our estimates, we might be required to use working capital to satisfy these claims rather than to maintain or expand our operations. To the extent that we experience a material increase in the frequency or severity of accidents or workers’ compensation and health claims, or unfavorable developments on existing claims, our results of operations and financial condition could be materially and adversely affected.
15
We contribute to multiemployer plans that could result in liabilities to us if those plans are terminated or if we withdraw from those plans.
We contribute to several multiemployer pension plans for employees covered by collective bargaining agreements. These plans are not administered by us and contributions are determined in accordance with provisions of negotiated labor contracts. The Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980, imposes certain liabilities upon employers who are contributors to a multiemployer plan in the event of the employer’s withdrawal from, or upon termination of, such plan. If we terminate, withdraw or partially withdraw from other multiemployer pension plans, we could be required to make significant cash contributions to fund those plans unfunded vested benefit, which could materially and adversely affect our financial condition and results of operations; however, we are not currently able to determine the net assets and actuarial present value of the multiemployer pension plans’ unfunded vested benefits allocable to us, if any, and we are not presently aware of the amounts, if any, for which we may be contingently liable if we were to withdraw from any of these plans. In addition, if the funding level of any of these multiemployer plans becomes classified as “critical status” under the Pension Protection Act of 2006, we could be required to make significant additional contributions to those plans.
Risks Related to Legal and Regulatory Matters
We are, and may continue to be, involved in routine litigation and government inquiries in the ordinary course of business.
Due to the nature of our business, we are involved in routine litigation or subject to other disputes or claims related to our business activities, including, among other things, workers’ compensation claims, employment-related disputes and issues related to liability, breach of contract or tortious conduct in connection with our performance of services and provision of materials. The outcomes of these inquiries and legal proceedings are not expected to have a material effect on our financial position or results of operations on an individual basis, although adverse outcomes in a significant number of such ordinary course inquiries and legal proceedings could, in the aggregate, have a material adverse effect on our financial condition and results of operations.
Environmental and other regulatory matters, including those relating to climate change, could adversely affect our ability to conduct our business and could require expenditures that could have a material adverse effect on our results of operations and financial condition. In addition, future regulations, or more stringent enforcement of existing regulations, could increase those costs and liabilities, which could adversely affect our financial position and results of operations.
Our operations are subject to various environmental laws and regulations relating to the management, disposal and remediation of hazardous substances and the emission and discharge of pollutants into the air and water. We could be held liable for contamination created not only from our own activities but also from the historical activities of others on our project sites or on properties that we acquire or lease. Our operations are also subject to laws and regulations relating to workplace safety and worker health, which, among other things, regulate employee exposure to hazardous substances. Violations of laws and regulations could subject us to substantial fines and penalties, cleanup costs, third party property damage or personal injury claims, natural resource damages claims, the issuance of orders enjoining our operations and administrative, civil and criminal liability.
In addition, growing concerns about climate change and other environmental issues could result in the imposition of additional environmental regulations. Legislation or restrictions could increase the costs of projects for us and, in some cases, prevent a project from going forward, thereby potentially reducing the need for our services which could in turn have a material adverse effect on our operations and financial condition.
Generally, environmental laws, regulations, enforcement practices and compliance standards have become increasingly stringent. Compliance with new regulations could require us to make substantial expenditures for, among other things, pollution control systems and other equipment that we do not currently possess, or the acquisition or modification of permits applicable to our activities.
Our aggregate quarry leases could subject us to costs and liabilities. We could be held responsible for any contamination or regulatory violations resulting from activities or operations at the quarries, which could be significant and could materially and adversely affect our business, operating results and financial condition.
16
We are required to obtain, maintain and comply with government permits, licenses and approvals, and failure to obtain, maintain, and comply with such permits, licenses and approvals could adversely affect our or our customers’ operations.
We, as well as our customers, are required to obtain, maintain, and comply with numerous federal, state and local government permits, licenses and approvals. Any of these permits, licenses or approvals may be subject to denial, revocation or modification under various circumstances. Failure to obtain or maintain such approvals or to comply with the conditions of permits, licenses or approvals may adversely affect our operations by, for instance, temporarily suspending our activities or curtailing our work and may subject us to fines, penalties, injunctive relief and other sanctions. Although existing permits and licenses are routinely renewed by various regulators, renewal could be denied or jeopardized by various factors, including:
• failure to provide adequate financial assurance for closure;
• failure to comply with environmental, health and safety laws and regulations or permit conditions; and
• executive action.
Furthermore, the regulatory permitting process for various projects requires significant investments of time and money by our customers and sometimes by us. We cannot guarantee that we or our customers will obtain the necessary permits for these projects.
Recent and potential changes in U.S. trade policies and retaliatory responses from other countries may significantly increase the costs or limit supplies of materials and products used in our projects.
In the recent past, the federal government imposed new or increased tariffs or duties on an array of imported materials and goods used in connection with our projects, which raised our costs for these items (or products made with them). Foreign governments, including China, Canada and Mexico, and trading blocs, such as the European Union, have responded by imposing or increasing tariffs, duties and/or trade restrictions on U.S. goods. Any trading conflicts and related escalating governmental actions that result in additional tariffs, duties and/or trade restrictions could increase our costs further, cause disruptions or shortages in our supply chains and/or negatively impact the U.S., regional or local economies, and, individually or in the aggregate, materially and adversely affect our business and result of operations.
Tax matters, including changes in corporate tax laws and disagreements with taxing authorities, could impact our results of operations and financial condition.
We conduct business across the United States and file income taxes in federal and various state jurisdictions. Significant judgment is required in our accounting for income taxes. In the ordinary course of our business, there are transactions and calculations in which the ultimate tax determination is uncertain. Changes in tax laws and regulations, in addition to changes and conflicts in related interpretations and other tax guidance, could materially impact our provision for income taxes, deferred tax assets and liabilities, and liabilities for uncertain tax positions. Issues relating to tax audits or examinations and any related interest or penalties and uncertainty in obtaining deductions or credits claimed in various jurisdictions could also impact the accounting for income taxes. Our results of operations are reported based on our determination of the amount of taxes we owe in various tax jurisdictions, which are subject to review or examination by taxing authorities in applicable tax jurisdictions. An adverse outcome of such a review or examination could adversely affect our operating results and financial condition. Further, the results of tax examinations and audits could have a negative impact on our financial results and cash flows where the results differ from the liabilities recorded in our financial statements.
Our business is subject to complex and evolving laws and regulations regarding data privacy and cybersecurity.
In the ordinary course of our business, we collect, use, store, and process personal information relating to our employees, vendors, and suppliers, and we may share such information with third‑party service providers for limited purposes under contractual arrangements.
Although we have implemented commercially reasonable measures to comply with applicable data privacy and cybersecurity laws and regulations, many of these laws are relatively new and subject to interpretation, and there can be no assurance that our compliance efforts will be deemed sufficient.
We use artificial intelligence (“AI”) technologies in our business, and the deployment, use, and maintenance of these technologies involve significant technological and legal risks.
We invest in AI, but face challenges: an evolving market, unproven growth, and potential development failures. We currently use third-party tools and are developing our AI strategy with external vendors. Risks include flawed algorithms, biased data, intense competition, and the inability to commercialize AI offerings effectively. The rapidly changing legal landscape, including privacy and consumer protection laws, poses unpredictable compliance costs. Ultimately, AI investments may not always benefit our business.

Risks Related to Strategy and Acquisitions
Our strategy, which includes expanding into adjacent markets, may not be successful.
We continue to pursue growth through the acquisition of companies or assets that will enable us to broaden the types of projects we execute and also expand into new markets. We have completed several acquisitions and plan to consider strategic acquisitions in the future. We may be unable to implement this growth strategy if we cannot identify suitable companies or assets or reach agreement on potential strategic acquisitions on acceptable terms. Moreover, an acquisition involves certain risks, including:
•difficulties in the integration of operations, systems, policies and procedures;
•enhancements in controls and procedures including those necessary for a public company may make it more difficult to integrate operations and systems;
•failure to implement proper overall business controls, including those required to support our growth, resulting in inconsistent operating and financial practices at companies we acquire or have acquired;
•termination of relationships with the key personnel and customers of an acquired company;
•additional financial and accounting challenges and complexities in areas such as tax planning, treasury management, financial reporting and internal controls;
•the incurrence of environmental and other liabilities, including liabilities arising from the operation of an acquired business or asset prior to our acquisition for which we are not indemnified or for which the indemnity is inadequate;
•assumption of contractual obligations that contain terms that are not beneficial to us or increase our risk for liability;
•insufficient management attention to our ongoing business; and
•inability to realize the cost savings or other financial benefits that we anticipate.
Our failure to address these risks or other problems encountered in connection with any future acquisitions could cause us to fail to realize the anticipated benefits of these acquisitions, cause us to incur unanticipated liabilities and harm our business generally. Future acquisitions could also result in dilutive issuances of the combined company’s equity securities, the incurring of debt, contingent liabilities, amortization expenses or the write-off of goodwill, any of which may adversely affect our business, prospects, liquidity, financial condition, and results of operations.
Risks Related to Our Financial Results, Financing and Liquidity
Our use of over time revenue recognition (formerly known as percentage-of-completion method) accounting related to our projects could result in a reduction or elimination of previously reported revenue and profits.
As is more fully discussed in Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations–Critical Accounting Estimates,” we recognize contract revenue over time. This method is used because management considers the cost-to-cost measure of progress to be the best measure of progress on these contracts.
Under this method, estimated contract revenue is recognized by applying the cost-to-cost measure of progress for the period (based on the ratio of costs incurred to total estimated costs of a contract) to the total estimated revenue for the contract. Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, and the performance of subcontractors. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. These adjustments could result in both increases and decreases in profit margins or losses. Actual results could differ from estimated amounts and could result in a reduction or elimination of previously recognized earnings. In certain circumstances, it is possible that such adjustments could be significant and could have an adverse effect on our business. To the extent that these adjustments result in an increase, a reduction or an elimination of previously reported contract profit, we recognize a credit or a charge against current earnings, which could be material.
We may not be able to fully realize the revenue value reported in our Backlog.
Backlog as of December 31, 2025 totaled $3.01 billion. Backlog develops as a result of new awards, which represent the potential revenue value realizable pursuant to new project commitments received by us during a given period. Backlog is measured and defined differently by companies within our industry. We refer to “Backlog” as the unearned revenue we expect to earn in future periods on our executed contracts. As the construction on our projects progresses, we increase or decrease Backlog to take into account newly signed contracts, revenue earned during the period and our estimates of the effects of changes in estimated quantities, changed conditions, change orders and other variations from previously anticipated contract revenues, including completion penalties and incentives. In the event of a project cancellation, termination, or scope adjustment, we typically have no contractual right to the total revenues reflected in our Backlog. The timing of contract awards, duration of
18
large new contracts and the mix of services can significantly affect Backlog reporting. We cannot guarantee that the revenue projected in our Backlog will be realized, or if realized, will result in earnings.
Given these factors, our Backlog at any point in time may not accurately represent the revenue that we expect to realize during any period, and our Backlog as of the end of a fiscal year may not be indicative of the revenue we expect to earn in the following fiscal year and should not be viewed or relied upon as a stand-alone indicator. Consequently, we cannot provide assurance that our estimates of Backlog will accurately reflect future revenue. Inability to realize revenue from our Backlog could have an adverse effect on our business.
We may need to raise additional capital in the future for working capital, capital expenditures and/or acquisitions, and we may not be able to do so on favorable terms or at all, which would impair our ability to operate our business or achieve our growth objectives.
Our ability to obtain additional financing in the future will depend in part upon prevailing credit and equity market conditions, as well as the condition of our business and our operating results; such factors may adversely affect our efforts to arrange additional financing on terms satisfactory to us and makes us more vulnerable to adverse economic and competitive conditions.
We have pledged substantially all of our assets as collateral in connection with that certain amended and restated credit agreement, dated as of June 5, 2025, by and among the Company, as borrower, certain of our subsidiaries, as guarantors, the financial institutions party thereto as lenders and BMO Bank N.A., as administrative agent for the lenders (as amended, the “Credit Agreement”), and we have additionally pledged the proceeds of and other rights under our E-Infrastructure Solutions and Transportation Solutions contracts to our bonding agent. As a result, we may have difficulty in obtaining additional financing in the future if such financing requires us to pledge assets as collateral. In addition, under our Credit Agreement, we must obtain the consent of our lenders to incur additional debt from other sources (subject to certain limited exceptions).
If adequate funds are not available, or are not available on acceptable terms, we may not be able to make future investments, take advantage of acquisitions or other opportunities, or respond to competitive challenges.
Our Credit Agreement contains various covenants and other provisions that impose restrictions on our ability to operate and manage our business.
As of December 31, 2025, our aggregate principal amount outstanding under the Credit Agreement was $292.5 million. The Credit Agreement will mature on June 5, 2028. While we currently believe we will have the financial resources to meet or refinance our obligations when they come due, we cannot fully anticipate our future performance or financial condition, the future condition of the credit markets or the economy generally.
The Credit Agreement is secured by a first priority security interest in substantially all of our assets, subject to certain exceptions and limitations. The Credit Agreement contains various affirmative and negative covenants that may, subject to certain exceptions, restrict our ability to, among other things, grant liens, incur additional indebtedness, make loans, advances or other investments or make certain acquisitions, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, purchase, redeem or otherwise acquire or retire capital stock or other equity interests, or merge or consolidate with any other person, among various other things.
In addition, the Credit Agreement contains financial covenants that require us to maintain certain financial ratios and to prepay outstanding loans under the Credit Agreement in certain cases with proceeds from the issuance of additional debt, asset dispositions, and events of loss. These requirements could limit our cash flow or impair our ability to conduct business and pursue business strategies. Our ability to comply with these provisions may be affected by events beyond our and their control. Failure to comply with these covenants could result in an event of default, which, if not cured or waived, could accelerate our debt repayment obligations, which in turn may trigger cross-acceleration or cross-default provisions in other debt or bonding agreements. The Credit Agreement also contains a cross-default provision. This provision could have a wider impact on liquidity than might otherwise arise from a default of a single debt instrument. Our available cash and liquidity would not be sufficient to fully repay borrowings under all of our debt instruments that could be accelerated upon such an event of default.
Further, our level of indebtedness could have important other consequences to our business, including the following:
•limiting our flexibility in planning for, or reacting to, changes in the industry in which we operate;
•increasing our vulnerability to general adverse economic and infrastructure industry conditions;
•limiting our ability to fund future working capital and capital expenditures because of the need to dedicate a substantial portion of our cash flows from operations to payments on our debt service;
•placing us at a competitive disadvantage compared to our competitors that have less debt;
19
•limiting our ability to borrow additional funds or refinance existing debt; or
•requiring that we pledge substantial collateral, which may limit flexibility in operating our business and restrict our ability to sell assets.
We may elect to borrow, continue or convert certain term or revolving loans under our Credit Agreement to bear interest at either a base rate plus a margin, or Secured Overnight Financing Rate (“Term SOFR”) plus a margin, at the Company’s election. Accordingly, increases in interest rates could have a material adverse effect on our business operations, financial performance and financial condition.
To service our indebtedness and to fund working capital, we will require a significant amount of cash. Our ability to generate cash depends on many factors that are beyond our control, including that adverse capital and credit market conditions may affect our ability to meet liquidity needs, access to capital and cost of capital.
Our ability to generate cash, outside of funds available through the revolving credit facility under the Credit Agreement, is subject to our operational performance, as well as general factors that are beyond our control. We may be unable to expand our credit capacity, which could adversely affect our operations and business. Earnings from our operations and our working capital requirements can vary from period to period, based primarily on the mix of our projects underway and the percentage of project work completed during the period. Capital expenditures may also vary significantly from period to period. We cannot provide assurance that our business will generate sufficient cash flow from operations or asset sales or that we can obtain future borrowing capacity in an amount sufficient to enable us to pay our indebtedness, to fund working capital requirements or to fund our other liquidity needs. Without sufficient liquidity, we will be forced to curtail our operations.
In the event we cannot generate enough cash to satisfy our liquidity needs, we may have to seek additional financing. The Credit Agreement, subject to certain exceptions, restricts our ability to incur additional financing indebtedness. The availability of additional financing will depend on a variety of factors such as market conditions, the general availability of credit, the volume of trading activities, our credit ratings and credit capacity. The domestic and worldwide capital and credit markets may experience significant volatility, disruptions and dislocations with respect to price and credit availability. Should we need additional funds or to refinance our existing indebtedness, we may not be able to obtain such additional funds. If internal sources of liquidity prove to be insufficient, we may not be able to successfully obtain additional financing on favorable terms, or at all.
We may need to refinance all or a portion of our indebtedness on or before maturity. Our inability to refinance our debt on commercially reasonable terms also could have a material adverse effect on our business. If we experience operational difficulties, we may need to increase our available borrowing capacity or seek amendments to the terms of our Credit Agreement.
We must manage our liquidity carefully to fund our working capital.
The need for working capital for our business varies due to fluctuations in the following amounts, among other factors:
•receivables;
•contract retentions;
•contract assets;
•contract liabilities;
•the size and status of contract mobilization payments and progress billings; and
•the amounts owed to suppliers and subcontractors.
We may have limited cash on hand and the timing of payments on our contract receivables is difficult to predict. If the timing of payments on our receivables is delayed or the amount of such payments is less than expected, our liquidity and ability to fund working capital could be materially and adversely affected.
We may be required to write down all or part of our goodwill and intangibles.
We had approximately $585 million of goodwill and $555 million of intangibles recorded on our Consolidated Balance Sheet at December 31, 2025. Goodwill represents the excess of cost over the fair value of net assets acquired in business combinations reduced by any impairments recorded subsequent to the date of acquisition. Intangible assets are recognized as an asset apart from goodwill if they arise from contractual or other legal rights or if they are separable; that is, they are capable of being separated or divided from the acquired business and sold, transferred, licensed, rented or exchanged (whether or not there is intent to do so). A shortfall in our revenues or net income or changes in various other factors from that expected by securities analysts and investors could significantly reduce the market price of our common stock. If our market capitalization drops significantly below the amount of net equity recorded on our balance sheet, it might indicate a decline in our fair value and
20
would require us to further evaluate whether our goodwill or intangible assets have been impaired. We perform an annual test of our goodwill and periodic assessments of intangible assets to determine if they have become impaired. On an interim basis, we also review the factors that have or may affect our operations or market capitalization for events that may trigger impairment testing. Write downs of goodwill and intangible assets may be substantial. If we were required to write down all or a significant part of our goodwill and/or intangible assets in future periods, our net earnings and equity could be materially adversely affected.
Failure to maintain adequate financial and management processes and internal controls could lead to errors in reporting our financial results.
The accuracy of our financial reporting is dependent on the effectiveness of our internal controls. We are required to provide a report from management to our shareholders on our internal control over financial reporting that includes an assessment of the effectiveness of these controls. Internal control over financial reporting has inherent limitations, including human error, the possibility that controls could be circumvented or become inadequate because of changed conditions, resource challenges and fraud. Because of these inherent limitations, internal control over financial reporting might not prevent or detect all misstatements or fraud. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, otherwise fail to prevent financial reporting misstatements, or if we experience difficulties in implementing internal controls, our business and operating results could be harmed, and we could fail to meet our financial reporting obligations. Please refer to Item 9A of this annual report on Form 10-K for further information.
Risks Related to Our Common Stock
We cannot guarantee that our Stock Repurchase Program will be fully implemented or that it will enhance long-term stockholder value.
Effective November 12, 2025, the Board of Directors approved a program authorizing us to repurchase up to $400 million of our outstanding common stock over a 24-month period (the “Stock Repurchase Program”). The timing and amount of any share repurchases is at the discretion of our management, subject to the requirements of the Securities Exchange Act of 1934, as amended, and related rules. As a result, there can be no guarantee around the timing or volume of our share repurchases. We intend to finance any stock repurchases with cash on hand and through operating cash flow. There is no guarantee as to the number of shares that will be repurchased, and the Stock Repurchase Program may be extended, suspended or discontinued at any time without notice at our discretion, which may result in a decrease in the trading price of our common stock. The Stock Repurchase Program could increase volatility in and affect the price of our common stock. The existence of our Stock Repurchase Program could also cause the price of our common stock to be higher than it would be in the absence of such a program and could potentially reduce the market liquidity for our common stock. Additionally, repurchases under our Stock Repurchase Program will diminish our cash reserves. There can be no assurance that any share repurchases will enhance stockholder value because the market price of our common stock may decline below the levels at which we repurchased such shares. Any failure to repurchase shares after we have announced our intention to do so may negatively impact our reputation and investor confidence in us and may negatively impact our stock price. Although our Stock Repurchase Program is intended to enhance long-term stockholder value, short-term stock price fluctuations could reduce the program’s effectiveness.
Provisions in our amended and restated certificate of incorporation and in Delaware law may discourage a takeover attempt.
Our certificate of incorporation authorizes our Board of Directors to issue, without stockholder approval, one or more series of preferred stock having such preferences, powers and relative, participating, optional and other rights (including preferences over the common stock respecting dividends and distributions and voting rights) as the Board of Directors may determine. The issuance of this “blank-check” preferred stock could render more difficult or discourage an attempt to obtain control by means of a tender offer, merger, proxy contest or otherwise. Additionally, certain provisions of the Delaware General Corporation Law or even certain provisions of our credit agreement may also discourage takeover attempts that have not been approved by the Board of Directors.
The price of our common stock has experienced volatility.
The price of our common stock has experienced volatility. Our stock price may continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors, including the other factors discussed in “Risks Factors,” variations in our quarterly operating results from our expectations or those of securities analysts or investors, downward revisions in securities analysts’ estimates, and announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments.

Performance Graph
The following Performance Graph and related information shall not be deemed to be filed with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933 or Securities Exchange Act of 1934, each as amended, except to the extent that we specifically incorporate it by reference into such filing.
The following graph compares the percentage change in the Company’s cumulative total stockholder return on its common stock for the last five years with the Dow Jones US Total Return Index, a broad market index, and a peer group index selected by our management that includes public companies within our industry (the “2025 Peer Group”).
The 2025 Peer Group index replaced the 2024 Peer Group index that was reported in the previous year. The companies in the 2025 Peer Group were selected because they comprise a broad group of publicly held corporations, each of which has some operations similar to ours. When taken as a whole, management believes the 2025 Peer Group more closely resembles our total business than any individual company in the 2025 Peer Group and more than the 2024 Peer Group as a whole.
The returns are calculated assuming that an investment with a value of $100 was made in the Company’s common stock and in each index on December 31, 2020 and that all dividends were reinvested in additional shares of common stock; however, the Company has paid no dividends during the periods shown. The graph lines merely connect the measuring dates and do not reflect fluctuations between those dates. Additionally, the stock performance shown on the graph is not intended to be indicative of future stock performance.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following “Management’s Discussion and Analysis of Financial Condition and Results of Operations” is provided to assist readers in understanding our financial performance during the periods presented and significant trends that may impact our future performance. This discussion should be read in conjunction with our Consolidated Financial Statements and the related notes thereto.
OVERVIEW
General—Sterling operates through a variety of subsidiaries within three segments specializing in E-Infrastructure, Transportation and Building Solutions in the United States, primarily across the Southern, Northeastern, Mid-Atlantic and Rocky Mountain regions and the Pacific Islands. E-Infrastructure Solutions provides advanced, large-scale site development services and mission-critical electrical services for data centers, semiconductor fabrication, manufacturing, distribution centers, warehousing, power generation and more. Transportation Solutions includes infrastructure and rehabilitation projects for highways, roads, bridges, airports, ports, rail and storm drainage systems. Building Solutions includes residential and commercial concrete foundations for single-family and multi-family homes, parking structures, elevated slabs, other concrete work, plumbing services, and surveys for new single-family residential builds. From strategy to operations, we are committed to sustainability by operating responsibly to safeguard and improve society’s quality of life. Caring for our people and our communities, our customers and our investors – that is The Sterling Way.
SIGNIFICANT TRANSACTIONS
RHB Deconsolidation—Since 2012, the Company has held a 50% ownership interest in Road and Highway Builders, LLC (“RHB”), with Rich Buenting holding the remaining 50% ownership interest. Historically, the Company fully consolidated the entity as a result of its exercise of control of the entity. On December 31, 2024, the parties executed an amendment to the RHB operating agreement to ensure the continuation of this mutually beneficial relationship while addressing the evolving needs and interest of both parties. This amendment modified the way RHB would be dispositioned in the event of the death or disability of Mr. Buenting and provides that in such event, Sterling and Mr. Buenting’s estate must agree on one of four alternatives: (1) continuation of the existing ownership structure, (2) acquisition of Sterling’s 50% interest by Mr. Buenting’s estate at fair market value, (3) acquisition of Mr. Buenting’s 50% interest by Sterling at fair market value or (4) the joint sale of RHB to a third party at fair market value.
Under GAAP, this contractual change required Sterling to no longer consolidate RHB’s results with its own and to use equity method accounting with respect to Sterling’s interest in the entity. Beginning January 1, 2025, the Company reports its portion of RHB’s income as a single line item (“Other operating income (expense), net”) in the Consolidated Statements of Operations and reports its interest in RHB at December 31, 2024, and thereafter, as a single line item (“Investment in unconsolidated subsidiary”) in the Consolidated Balance Sheets. RHB’s revenue is no longer included in Sterling’s consolidated revenue in 2025 and Sterling’s consolidated backlog figures as of December 31, 2024, and thereafter, do not include RHB’s backlog.
Drake Acquisition—During the first quarter of 2025, Sterling acquired Drake Concrete, LLC (“Drake”) (the “Drake Acquisition”). Drake provides concrete slabs for residential home builders in the Dallas-Fort Worth market. The acquisition strengthens Sterling’s geographic footprint within the DFW metroplex and expands and deepens the customer base, given limited customer overlap with Tealstone. The purchase price was $25 million in cash plus a four year earn-out opportunity. The results of Drake are included in our Building Solutions segment.
CEC Acquisition—On September 1, 2025, the Company acquired substantially all of the assets of Irving, Texas-based CEC Facilities Group, LLC (“CEC”) a leading specialty electrical and mechanical contractor. The purchase price was $562 million, consisting primarily of $443 million in cash and $79 million in common stock. Additionally, CEC has an earn-out opportunity of up to an aggregate of $80 million, contingent upon achieving certain operating income targets. CEC is included in the Company’s E-Infrastructure Solutions segment.
MARKET OUTLOOK AND TRENDS
We see favorable opportunities for long-term growth across each of our business segments. We remain focused on our strategic objectives, as described in Item 1 “Business — Business Strategy.” These objectives include: 1) growth in our E-Infrastructure Solutions segment, with particular focus on large, high-value projects; 2) risk reduction through a continued shift in our Transportation Solutions business away from low-bid heavy highway work, and toward alternative delivery and design-build projects; 3) continuing to grow market share and geographic presence in Building Solutions; and 4) improving our margins in each of our segments.
26
E-Infrastructure Solutions—Our E-Infrastructure Solutions business is driven by our customers’ investments in the development of data centers, advanced manufacturing centers, e-commerce distribution centers and warehouses. We foresee significant growth opportunities tied to the implementation of multi-year capital deployment plans by data center customers, including hyperscalers, colocation providers and others. These investments are driven by the need to support the increasing use of cloud computing applications, increasing adoption and complexity of artificial intelligence applications and digital transformation across industries. Additionally, we continue to see significant opportunity related to the construction of manufacturing capacity in the U.S., including semiconductor fabrication. Following a decline that began in 2023, the e-commerce distribution sector began to strengthen in 2025 and we expect this momentum to continue in 2026.
Transportation Solutions—Our Transportation Solutions business is primarily driven by federal, state and municipal funding. Federal funds, on average, provide 50% of annual State Department of Transportation capital outlays for highway and bridge projects. We benefit from a number of federal, state and local infrastructure investment programs. At the Federal level, the Infrastructure Investments and Jobs Act (“IIJA”), which establishes funding for the fiscal 2022 through 2026 time period, drove significant increases in transportation funding relative to the previous five-year law. The IIJA includes approximately $643 billion in funding for transportation programs ($432 billion for highways, $109 billion for transportation and $102 billion for rail), of which $284 billion is an increase over historic investment levels that will fund new transportation infrastructure. The IIJA also includes $25 billion of funding for airport modernization. As a result of the IIJA, we saw an increase in bid activity and project awards which started in the third quarter of 2022 and continued through 2025. In 2026, we expect that the combination of strong state-level funding in our core geographies and elevated federal funding will allow the transportation market to remain strong relative to historical levels.
Building Solutions—Our Building Solutions segment is comprised of our residential and commercial businesses. The segment is driven by new home starts in Dallas-Fort Worth, the segment’s largest market, and continued expansion in the Houston and Phoenix markets. Building Solutions' core customer base includes top national, regional and custom home builders in our areas. Beginning in the second half of 2024, demand from residential home builder customers began to decline, as prospective homebuyers struggled with affordability challenges. We anticipate that demand will remain muted in the near-term, but believe the dynamics in our markets, including population growth and structural housing shortages, support a return to growth over a multi-year time period.
BACKLOG
Our remaining performance obligations on our projects, as defined in ASC 606, do not differ from what we refer to as “Backlog.” Our Backlog represents the amount of revenues we expect to recognize in the future from our contract commitments on projects. The contracts in Backlog are typically completed in 6 to 36 months. Our unsigned awards (“Unsigned Awards”) are excluded from Backlog until the contract is executed by our customer. We refer to the combination of our Backlog and Unsigned Awards as “Combined Backlog.” Our book-to-burn ratio is determined by taking our additions to Backlog and dividing it by revenue for the applicable period. This metric allows management to monitor the Company’s business development efforts to ensure we grow our Backlog and our business over time, and management believes that this measure is useful to investors for the same reason.
At December 31, 2025, our Backlog was $3.01 billion, as compared to $1.69 billion at December 31, 2024, with a book-to-burn ratio of 1.6X for the year ended December 31, 2025. Included in Backlog at December 31, 2025 is $488.9 million contributed from the electrical and mechanical business acquired late in the third quarter 2025. The Company’s margin in Backlog has increased to 17.8% at December 31, 2025 from 16.7% at December 31, 2024, driven by a greater mix of E-Infrastructure Solutions backlog and an improved backlog margin mix within Transportation Solutions.
Unsigned Awards were $300.7 million at December 31, 2025 and $137.9 million at December 31, 2024. Included in Unsigned Awards at December 31, 2025 is $226.4 million contributed from the electrical and mechanical business acquired late in the third quarter 2025. Combined Backlog totaled $3.31 billion and $1.83 billion at December 31, 2025 and 2024, respectively, with a book-to-burn ratio of 1.7X for the year ended December 31, 2025.

| Gross margin | 23.0% | 20.1% | |||||||||
Revenues—Revenues were $2.49 billion for 2025, compared to $2.12 billion the prior year. Excluding $235.9 million of RHB revenue from 2024, revenues increased $610.2 million, which was driven by a $543.0 million increase in E-Infrastructure Solutions and a $92.9 million increase in Transportation Solutions, partly offset by a $25.8 million decrease in Building Solutions.
Gross profit and margin—Gross profit was $572.3 million for 2025, an increase of $146.2 million, or 34.3%, compared to the prior year. The Company’s gross margin as a percentage of revenue increased to 23.0% in 2025, as compared to 20.1% in the prior year. The increases were driven by the aforementioned higher revenue volume and an improved project margin mix across our E-Infrastructure and Transportation Solutions segments.
Our contracts are of various sizes, of different expected profitability and in various stages of completion. The nearer a contract progresses toward completion, the more visibility the Company has in refining its estimate of total revenues (including incentives, delay penalties and change orders), costs and gross profit. Thus, gross profit as a percentage of revenues can increase or decrease from comparable and subsequent quarters due to variations among contracts and the stage of completion of contracts.
General and administrative expenses—General and administrative expenses were $154.8 million, or 6.2% of revenue, for 2025, compared to $118.4 million, or 5.6% of revenue, in the prior year. The increase in expense reflects higher performance based compensation, one-time severance costs, increased headcount to support growth, and inflation in 2025.
Other operating income (expense), net—Other operating income (expense), net, includes the 50% portion of earnings related to our 50% owned subsidiary and occasionally other miscellaneous operating income or expense. In 2025, Sterling’s 50% portion of earnings is treated as income and increases the investment in unconsolidated subsidiary account. In 2024, the Members’ 50% portion of earnings was treated as an expense and an increase to the liability account. During 2025, Sterling’s 50% portion of earnings was $15.9 million (including basis step-up depreciation and amortization of $8.6 million), compared to $20.9 million of expense for the Members’ 50% portion of earnings in 2024.
Income taxes—The effective income tax rate was 24.2% in 2025 and 24.4% in the prior year. The rate varied from the statutory rate primarily as a result of state income taxes, nondeductible compensation, gain on the deconsolidation of subsidiary
28
and other permanent differences. On July 4, 2025, the One Big Beautiful Bill Act was enacted into law, introducing changes to the U.S. tax code. The changes did not have a material impact on our effective tax rate. See Note 12 - Income Taxes for more information.
Segment Results
The Company’s operations consist of three reportable segments: E-Infrastructure Solutions, Transportation Solutions and Building Solutions. We incur certain expenses at the corporate level that relate to our business as a whole. A portion of these expenses are allocated to our business segments by various methods, but primarily on the basis of usage. The balance of the corporate level expenses are reported in the “Corporate G&A Expense” line, which is primarily comprised of corporate headquarters facility expense, the cost of the executive management team and other expenses pertaining to certain centralized functions that benefit the entire Company, but are not directly attributable to any specific business segment, such as corporate human resources, legal, governance, compliance and finance functions.

E-Infrastructure Solutions
Revenues—Revenues were $1,466.8 million for 2025, an increase of $543.0 million, or 58.8%, compared to the prior year. The increase was primarily driven by higher volume from data centers and the inclusion of $170.4 million of revenue from the electrical and mechanical business acquired late in the third quarter 2025, partly offset by lower volume from warehouses and the timing of advanced manufacturing projects.
Operating income—Operating income was $346.0 million, or 23.6% of revenue, for 2025, an increase of $142.7 million compared to $203.4 million, or 22.0% of revenue, in the prior year. The increase in operating income is partly attributable to a $19.4 million (inclusive of $3.0 million of intangible amortization) contribution from the electrical and mechanical business acquired late in the third quarter 2025, and the remaining increases in operating income and margin were driven by a project mix shift toward large mission-critical projects, partly offset by lower volume from warehouses and the timing of advanced manufacturing projects.
Transportation Solutions
Revenues—Revenues were $640.7 million for 2025, compared to $783.7 million in the prior year. Excluding $235.9 million of RHB revenue from 2024, revenues increased $92.9 million or 17%. The increase was driven by higher heavy highway and other non-highway service revenue, partly offset by lower aviation revenue.
Operating income—Operating income was $77.8 million, or 12.1% of revenue, for 2025, an increase of $26.9 million compared to $50.9 million, or 6.5% of revenue, in the prior year. The increases in operating income and margin were driven by an improved project margin mix.
29
Building Solutions
Revenues—Revenues were $382.6 million for 2025, a decrease of $25.8 million, or 6.3%, compared to the prior year. The decrease was driven by lower commercial volume compared to 2024. Our residential concrete slab and plumbing businesses have also been impacted by a slowdown in all markets in 2025, driven by prospective homebuyers struggling with affordability challenges.
Operating income—Operating income was $39.1 million, or 10.2% of revenue, for 2025, a decrease of $14.8 million compared to $53.8 million, or 13.2% of revenue, in the prior year. The decrease in operating income and margin were driven by the aforementioned lower volume and the slowdown in residential markets in 2025.
LIQUIDITY AND SOURCES OF CAPITAL
Cash and Cash Equivalents—Total cash and cash equivalents at December 31, 2025 and 2024 were $390.7 million and $664.2 million, respectively, and included the following components:
| As of December 31, | |||||||||||

| Net change in cash and cash equivalents | $ | (273,474) | $ | 192,632 | |||||||
Operating Activities—During 2025, net cash provided by operating activities was $440.0 million compared to net cash provided by operating activities of $497.1 million in the prior year. Cash flows provided by operating activities were primarily driven by higher operating income, the collection of receivables from affiliate, distributions of earnings from our unconsolidated subsidiary, and changes in our accounts receivable, net contracts in progress and accounts payable balances (collectively, “Contract Capital”), as discussed below.
Changes in Contract Capital—The change in operating assets and liabilities varies due to fluctuations in operating activities and investments in Contract Capital. The changes in components of Contract Capital during the years ended December 31, 2025 and 2024 were as follows:
| Years Ended December 31, | |||||||||||
| (In thousands) | 2025 | 2024 | |||||||||
| Contracts in progress, net | $ | 84,024 | $ | 194,306 | |||||||

| Accounts payable | 33,111 | (9,336) | |||||||||
| Change in Contract Capital, net | $ | (54,229) | $ | 185,510 | |||||||
During 2025, the change in Contract Capital was $54.2 million, which was primarily driven by the E-Infrastructure Solutions segment due to the increased size and duration of its projects in progress. The Company’s Contract Capital fluctuations are impacted by the mix of projects in Backlog, seasonality, the timing of new awards and related payments for work performed and the contract billings to the customer as projects are completed. Contract Capital is also impacted at period-end by the timing of accounts receivable collections and accounts payable payments for projects.
Investing Activities—During 2025, net cash used in investing activities was $551.9 million, compared to net cash used of $185.8 million in the prior year. The net cash used during the period was primarily driven by $482.3 million for acquisitions (including $442.9 million for the CEC Acquisition and $25 million for the Drake Acquisition) and $77.3 million for purchases
30
of capital equipment, partly offset by $5.7 million of cash proceeds from the sale of property and equipment. Capital equipment is acquired as needed to support changing levels of production activities and to replace retiring equipment.
Financing Activities—During 2025, net cash used in financing activities was $161.5 million compared to net cash used of $118.6 million in the prior year. The financing cash outflow during the period was primarily driven by $74.2 million for the repurchase of common stock, $40.1 million for distributions to our noncontrolling interest partners, $24.7 million of repayments on the Term Loan Facility, and $21.0 million for withholding taxes paid on the net share settlement of vested equity awards.
Credit Facilities, Debt and Other Capital
General—In addition to our available cash, cash equivalents and cash provided by operations, from time to time we use borrowings to finance acquisitions, our capital expenditures and working capital needs.
Credit Facility—Our amended and restated Credit Agreement provides the Company with senior secured debt financing consisting of the following (collectively, the “Credit Facility”): (i) a senior secured first lien term loan facility (the “Term Loan Facility”) in the aggregate principal amount of $300 million and (ii) a senior secured first lien revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of up to $150 million (with a $75 million limit for the issuance of letters of credit and a $15 million sublimit for swing line loans). At December 31, 2025, we had $292.5 million of outstanding borrowings under the Term Loan Facility and no outstanding borrowings under the Revolving Credit Facility. The obligations under the Credit Facility are secured by substantially all assets of the Company and the subsidiary guarantors, subject to certain permitted liens and other customary exceptions. The Credit Facility will mature on June 5, 2028.
Compliance and Other—The Credit Agreement contains various affirmative and negative covenants that may, subject to certain exceptions, restrict our ability and the ability of our subsidiaries to, among other things, grant liens, incur additional indebtedness, make loans, advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, purchase, redeem or otherwise acquire or retire capital stock or other equity interests, or merge or consolidate with any other person, among various other things. In addition, the Company is required to maintain certain financial covenants. See Note 9 - Debt for further discussion of these financial covenants. As of December 31, 2025, we were in compliance with all of our restrictive and financial covenants. The Company’s debt is recorded at its carrying amount in the Consolidated Balance Sheets. Based upon the current market rates for debt with similar credit risk and maturities, at December 31, 2025 the fair value of our debt outstanding approximated the carrying value, as interest is based on Term SOFR plus an applicable margin.
Borrowings—Based on our average borrowings for 2025 and our 2026 forecasted cash needs, we continue to believe that the Company has sufficient liquid financial resources to fund our requirements for the next year of operations. Furthermore, the Company is continually assessing ways to increase revenues and reduce costs to improve liquidity. However, in the event of a substantial cash constraint, and if we were unable to secure adequate debt financing, our liquidity could be materially and adversely affected.
Issuance of Common Stock—In addition to our available cash, cash equivalents and cash provided by operations and borrowings, from time to time we issue common stock to finance acquisitions.
Bonding—As is customary in the construction business, we are required to provide surety bonds to secure our performance under construction contracts. Our ability to obtain surety bonds primarily depends upon our capitalization, working capital, past performance, management expertise and reputation and certain external factors, including the overall capacity of the surety market. Surety companies consider such factors in relationship to the amount of our backlog and their underwriting standards, which may change from time to time. We have pledged all proceeds and other rights under our construction contracts to our bond surety company. Events that affect the insurance and bonding markets may result in bonding becoming more difficult to obtain in the future, or being available only at a significantly greater cost. To date, we have not encountered difficulties or material cost increases in obtaining new surety bonds.
Capital Strategy—The Company will continue to explore additional revenue growth and capital alternatives to improve leverage and strengthen its financial position in order to take advantage of trends in the markets in which we operate. The Company also expects to continue to pursue strategic uses of its cash, such as investing in projects or businesses that meet its gross margin and overall profitability targets, managing its debt balances and repurchasing shares of its common stock.

Material Cash Requirements
The following table sets forth our material cash requirements from contractual obligations at December 31, 2025:

| Total | $ | 330,157 | $ | 31,122 | $ | 299,035 | $ | — | $ | — | |||||||||||||||||||
Capital Expenditures—Capital equipment is acquired as needed by increased levels of production and to replace retiring equipment. Capital expenditures incurred in 2025 were $77.3 million. Management expects capital expenditures in 2026 to be in the range of $100 to $110 million; however, the award of a project requiring significant purchases of equipment or other factors could result in increased expenditures.
Earn-outs—In connection with certain acquisitions, we have agreed to make future payments contingent upon the achievement of specific financial performance targets by the acquired businesses over designated periods. These earn-out obligations are typically recorded as liabilities at their estimated fair value at the acquisition date and are subsequently remeasured at each reporting period, with changes in fair value recognized in the Consolidated Statements of Operations. As of December 31, 2025, our aggregate earn-out liabilities totaled approximately $57 million. The actual amounts ultimately paid may differ materially from these estimates due to various factors, including the performance of the acquired businesses, changes in market conditions, and other unforeseen events.
NEW ACCOUNTING STANDARDS
See the applicable section of Note 2 - Basis of Presentation and Significant Accounting Policies for a discussion of new accounting standards.
CRITICAL ACCOUNTING ESTIMATES
The discussion and analysis of the financial condition and results of operations are based on the Company’s Consolidated Financial Statements, which have been prepared in accordance with accounting policies generally accepted in the U.S. (“GAAP”). The preparation of these Consolidated Financial Statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures of contingent assets and liabilities. The Company continually evaluates its estimates based on historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. The Company believes the following critical accounting estimates involve more significant judgment used in the preparation of the Consolidated Financial Statements.
Revenue Recognition
Performance Obligations Satisfied Over Time—Revenue for contracts that satisfy the criteria for over time recognition is recognized as the work progresses. The Company measures transfer of control of the performance obligation utilizing the cost-to-cost measure of progress, with cost of revenue including direct costs, such as materials and labor, and indirect costs that are attributable to contract activity. Under the cost-to-cost approach, the use of estimated costs to complete each performance obligation is a significant variable in the process of determining recognized revenue and is a significant factor in the accounting for such performance obligations. Significant estimates that impact the cost to complete each performance obligation are materials, components, equipment, labor and subcontracts; labor productivity; schedule durations, including subcontractor or supplier progress; contract disputes, including claims; achievement of contractual performance requirements; and contingencies, among others. The cumulative impact of revisions in total cost estimates during the progress of work is reflected in the period in which these changes become known, including, to the extent required, the reversal of profit recognized in prior periods and the recognition of losses expected to be incurred on performance obligations in progress. Due to the various estimates inherent in contract accounting, actual results could differ from those estimates, which could result in material changes to the Company’s Consolidated Financial Statements and related disclosures. See “Contract Estimates” within Note 4 - Revenue from Customers for further discussion.
32
Fair Value Measurements
The Company may use fair value measurements that involve the input of estimates that require significant judgment. The Company’s use of these fair value measurements include:
•determining the purchase price allocation for an acquired business;
•determining the value of retained interest after the deconsolidation of a subsidiary;
•goodwill impairment testing when a quantitative analysis is deemed necessary; and
•long-lived asset (such as property, equipment and intangible assets) impairment testing when impairment indicators are present.
When performing quantitative fair value or impairment evaluations, the Company estimates the fair value of assets by considering the results of income-based and/or a market-based valuation method. Under the income-based method, a discounted cash flow valuation model uses recent forecasts to compare the estimated fair value of each asset to its carrying value. Cash flow forecasts are discounted using the weighted-average cost of capital for the applicable reporting unit at the date of evaluation. The weighted-average cost of capital is comprised of the cost of equity and the cost of debt with a weighting for each that reflects the Company’s current capital structure. Preparation of long-term forecasts involve significant judgments involving consideration of backlog, expected future awards, customer attribution, working capital assumptions and general market trends and conditions. Significant changes in these forecasts or any valuation assumptions, such as the discount rate selected, could affect the estimated fair value of our assets and could result in impairment. Under the market-based method, market information such as multiples of comparable publicly traded companies and/or completed sales transactions are used to develop or validate our fair value conclusions, when appropriate and available.
Purchase Price Allocations—The aggregate purchase price for acquisitions were allocated to the major categories of assets and liabilities acquired based upon their estimated fair values as of the closing date, which were based, in part, upon internal and external valuations of certain assets, including specifically identified intangible assets and property and equipment. The valuations were based on the income-based and market-based valuation methods noted above. The excess of the purchase price over the estimated fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. See Note 3 - Acquisitions for further discussion.
Goodwill—Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment or when other actions require an impairment assessment. The Company performs the annual impairment assessment for its reporting units during the fourth quarter of each year based on balances as of October 1. During the fourth quarters of 2025, 2024 and 2023, the Company performed a qualitative assessment of goodwill, and based on this assessment, no indicators of impairment were present. Factors considered include macroeconomic, industry and competitive conditions, financial performance and reporting unit specific events. These are discussed in a number of places including Item 1A “Risk Factors.” Our annual assessments indicated there was no impairment of goodwill during the years ended December 31, 2025, 2024 and 2023.
Long-lived Assets—Long-lived assets, which include property, equipment and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If a recoverability assessment is required, the estimated future cash flow associated with the asset or asset group will be compared to their respective carrying amounts to determine if an impairment exists. Actual useful lives and cash flows could be different from those estimated by management, and this could have a material effect on operating results and financial position. For the years ended December 31, 2025, 2024 and 2023, there were no events or changes in circumstances that would indicate a material impairment of our long-lived assets.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Risk
Our interest rate risk relates primarily to fluctuations in variable interest rates on our revolving credit facility and term loan facility (collectively, the “Credit Facility”) and our cash and cash equivalents balance. Our indebtedness as of December 31, 2025 included $292.5 million of variable rate debt under our Credit Facility. At December 31, 2025 a 100-basis point (or 1%) increase or decrease in the interest rate would increase or decrease interest expense by approximately $2.9 million per year. As of December 31, 2025, we held cash and cash equivalents of $390.7 million. At December 31, 2025 a 100-basis point (or 1%) increase or decrease in the interest rate would increase or decrease interest income by approximately $3.9 million per year.
Other
Fair Value—The carrying values of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate their fair values because of the short-term nature of these instruments. Based upon the current market rates for debt with similar credit risk and maturities, at December 31, 2025, the fair value of our debt outstanding approximated the carrying value, as interest is based on Term SOFR plus an applicable margin.
Inflation—While inflation did not have a material impact on our financial results for many years, since 2021, supply chain volatility and inflation has resulted in price increases in oil, fuel, lumber, concrete, steel and labor which have increased our cost of operations, and inflation has increased our general and administrative expense. Anticipated cost increases are considered in our bids to customers; however, inflation has had, and may continue to have, a negative impact on the Company’s financial results.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Board of Directors and Shareholders
Sterling Infrastructure, Inc.
Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Sterling Infrastructure, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 26, 2026 expressed an unqualified opinion.
Basis for opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical audit matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Revenue recognition over time
As described further in note 2 to the consolidated financial statements, revenues derived from certain contracts in the Transportation Solutions, E-infrastructure Solutions, and Building Solutions segments are recognized as the performance obligations are satisfied over time. The Company uses a ratio of project costs incurred to estimated total costs for each contract to recognize revenue. Under the cost-to-cost measure, the determination of progress towards completion requires management to prepare estimates of the costs to complete. We identified revenue recognized over time to be a critical audit matter.
The principal consideration for our determination that revenue recognized over time is a critical audit matter is that auditing management’s estimate of the progress toward completion of its projects was complex and subjective. Considerable auditor judgment was required to evaluate management’s determination of the forecasted costs to complete its contracts as future results may vary significantly from past estimates due to changes in facts and circumstances.
36
Our audit procedures related to revenue recognized over time included the following, among others.
•We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company’s internal controls related to the initial and ongoing monitoring of changes in the contract cost-to-cost estimates.
•For a selection of contracts, we tested the Company’s cost-to-cost estimates by evaluating the appropriate application of the cost-to-cost method, testing the significant assumptions used to develop the estimated cost to complete and testing the completeness and accuracy of the underlying data.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Board of Directors and Shareholders
Sterling Infrastructure, Inc.
Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of Sterling Infrastructure, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2025, and our report dated February 26, 2026 expressed an unqualified opinion on those financial statements.
Basis for opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting (“Management’s Report”). Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Our audit of, and opinion on, the Company’s internal control over financial reporting does not include the internal control over financial reporting of Drake Concrete, LLC (“Drake”) and CEC Facilities Group, LLC (“CEC Facilities”), whose financial statements, in the aggregate, reflect total assets and revenues constituting 30% and 9% respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2025. As indicated in Management’s Report, Drake and CEC Facilities were acquired during 2025. Management’s assertion on the effectiveness of the Company’s internal control over financial reporting excluded internal control over financial reporting of Drake and CEC Facilities.
Definition and limitations of internal control over financial reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

| 2. | BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES | ||||
Basis of Presentation
Presentation Basis—The accompanying Consolidated Financial Statements are presented in accordance with accounting policies generally accepted in the United States (“GAAP”) and reflect all wholly owned subsidiaries and those entities the Company is required to consolidate. See the “50 % Owned Subsidiary” and “Construction Joint Ventures” sections of this Note for further discussion of the Company’s consolidation policy for those entities that are not wholly owned. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in consolidation. Values presented within tables (excluding per share data) are in thousands. Reclassifications have been made to historical financial data in the Consolidated Financial Statements to conform to the current year presentation.
Estimates and Judgments—The preparation of the accompanying Consolidated Financial Statements in conformance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates of the Company require a higher degree of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts over time, the valuation of long-lived assets, goodwill and purchase accounting estimates. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.
Significant Accounting Policies
•Performance Obligations Satisfied Over Time
Recognition of Performance Obligations—A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in the revenue standard. The contract transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Transportation Solutions and Business Solutions Commercial projects typically span between 12 to 36 months, and E-Infrastructure Solutions projects are between 6 to 24 months. The majority of our contracts have a single performance obligation, as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Occasionally, some contracts have multiple performance obligations, most commonly due to the contract covering multiple phases of the project life cycle (design and construction).
43
STERLING INFRASTRUCTURE, INC. & SUBSIDIARIES
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Revenues are recognized as our obligations are satisfied over time, using the ratio of project costs incurred to estimated total costs for each contract because of the continuous transfer of control to the customer as all of the work is performed at the customer’s site and, therefore, the customer controls the asset as it is being constructed. This continuous transfer of control to the customer is further supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay the Company for costs incurred plus a reasonable profit and take control of any work in process. This cost-to-cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs determined to relate to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes.
Items Excluded from Cost-to-Cost—Pre-contract costs are generally not material and are charged to expense as incurred, but in certain cases pre-contract recognition may be deferred if specific probability criteria are met. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.
Variable Consideration—Contract modifications through change orders, claims and incentives are routine in the performance of the Company’s contracts to account for changes in the contract specifications or requirements. In most instances, contract modifications are not distinct from the existing contract due to the significant integration of services provided in the contract and are accounted for as a modification of the existing contract and performance obligation. Either the Company or its customers may initiate change orders, which may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Change orders that are unapproved as to both price and scope are evaluated as claims. The Company considers claims to be amounts in excess of approved contract prices that the Company seeks to collect from its customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs.
The Company estimates variable consideration for a performance obligation at the most likely amount to which the Company expects to be entitled (or the most likely amount the Company expects to incur in the case of liquidated damages), utilizing estimation methods that best predict the amount of consideration to which the Company will be entitled (or will incur in the case of liquidated damages). The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.
The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders and claims reflected in transaction price (or excluded from transaction price in the case of liquidated damages) are not resolved in the Company’s favor, or to the extent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.
•Performance Obligations Satisfied at a Point-in-Time
Revenue for our Residential contracts is recognized at a point in time and utilizes an output measure for performance based on the completion of a unit of work (e.g., completion of concrete foundation). The time from starting construction to completion is typically two weeks or less. Upon fulfillment of the performance obligation, the customer is provided an invoice (or equivalent) demonstrating transfer of control to the customer.
Accounts Receivable—Receivables are generally based on amounts billed to the customer in accordance with contractual provisions. Receivables are written off based on the individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. The Company performs a review of outstanding receivables, historical collection information and existing economic conditions to determine if there are potential uncollectible receivables. At December 31, 2025 and 2024, our allowance for our estimate of expected credit losses was zero 252,435 , with changes during 2024 and 2025 primarily driven by the timing of billings and collections under customer contracts.
As is customary, we have agreed to indemnify our bonding company for all losses incurred by it in connection with bonds that are issued, and we have granted our bonding company a security interest in certain assets, including accounts receivable, as collateral for such obligations.
44
STERLING INFRASTRUCTURE, INC. & SUBSIDIARIES
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Contracts in Progress—For performance obligations satisfied over time, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Typically, Sterling bills for advances or deposits from its customers before revenue is recognized, resulting in contract liabilities. However, the Company occasionally bills subsequent to revenue recognition, resulting in contract assets.
Many of the contracts under which the Company performs work also contain retainage provisions. Retainage refers to that portion of our billings held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. At December 31, 2025 and 2024, contract assets included $40,747 and $38,111 of retainage, respectively, and contract liabilities included $147,580 and $91,917 of retainage, respectively. Retainage on active contracts is classified as current regardless of the term of the contract and is generally collected within one year of the completion of a contract. We anticipate collecting approximately 70 % of our December 31, 2025 retainage in 2026. Retainage is reported on the Consolidated Balance Sheets within “Contract assets” and “Contract liabilities” on a contract-by-contract basis at the end of each reporting period.
Contract assets increased by $45,767 compared to December 31, 2024, primarily due to the acquisition of CEC (see Note 3 - Acquisitions for more information), higher unbilled revenue, and an increase in retainage. Contract liabilities increased by $143,511 compared to December 31, 2024, due to the timing of advance billings and work progression and the acquisition of CEC, partly offset by an increase in retainage. Revenue recognized for the year ended December 31, 2025 that was included in the contract liability balance on December 31, 2024 was $382,775 . The balances of contract assets and contract liabilities at December 31, 2023 were $88,600 and $444,160 , respectively, with changes during 2024 reflecting the timing of advance billings, revenue recognition, and retainage activity. Revenue recognized for the year ended December 31, 2024 that was included in the contract liability balance on December 31, 2023 was $357,581 .
50% Owned Subsidiary—Since 2012, the Company has held a 50 % ownership interest in Road and Highway Builders, LLC (“RHB”), with Rich Buenting holding the remaining 50 % ownership interest. Historically, the Company fully consolidated the entity as a result of its exercise of control of the entity. On December 31, 2024, the parties executed an amendment to the RHB operating agreement to ensure the continuation of this mutually beneficial relationship while addressing the evolving needs and interest of both parties. This amendment modified the way RHB would be dispositioned in the event of the death or disability of Mr. Buenting and provides that in such event, Sterling and Mr. Buenting’s estate must agree on one of four alternatives: (1) continuation of the existing ownership structure, (2) acquisition of Sterling’s 50 % interest by Mr. Buenting’s estate at fair market value; (3) acquisition of Mr. Buenting’s 50 % interest by Sterling at fair market value; or (4) the joint sale of RHB to a third party at fair market value.
Under GAAP, this contractual change required Sterling to no longer consolidate RHB’s results with its own and to use equity method accounting with respect to Sterling’s interest in the entity. Beginning January 1, 2025, the Company reports its portion of RHB’s income as a single line item (“Other operating income (expense), net”) in the Consolidated Statements of Operations and reports its interest in RHB at December 31, 2024 and thereafter, as a single line item (“Investment in unconsolidated subsidiary”) in the Consolidated Balance Sheets. RHB’s revenue is no longer included in Sterling’s consolidated revenue in 2025 and Sterling’s consolidated remaining performance obligations (“RPOs”) as of December 31, 2024 and thereafter, do not include RHB’s RPOs.
Prior to the contractual change, the subsidiary had a mandatory redemption provision which, under circumstances outlined in the previous operating agreement, was certain to occur and obligated the Company to purchase the partner’s remaining 50 % interests for $20,000 . This amount, along with any undistributed earnings, were included in “Members’ interest subject to mandatory redemption and undistributed earnings” within the Consolidated Balance Sheets as a liability. Upon the contractual change, we derecognized the liability and recognized our retained equity method interest in RHB at fair value, resulting in a net gain to the Company on December 31, 2024. See Note 5 - 50% Owned Subsidiary for more information.
Construction Joint Ventures—In the ordinary course of business, the Company executes specific projects and conducts certain operations through joint venture arrangements (referred to as “joint ventures”). The Company has various ownership interests in these joint ventures, with such ownership typically proportionate to the Company’s decision making and distribution rights.
Each joint venture is assessed at inception and on an ongoing basis as to whether it qualifies as a Variable Interest Entity (“VIE”) under the consolidations guidance in ASC Topic 810. If at any time a joint venture qualifies as a VIE, the Company performs a qualitative assessment to determine whether the Company is the primary beneficiary of the VIE and therefore needs to consolidate the VIE.
If the Company determines it is not the primary beneficiary of the VIE or only has the ability to significantly influence, rather than control the joint venture, it is not consolidated. The Company accounts for unconsolidated joint ventures using a

pro-rata basis in the Consolidated Statements of Operations and as a single line item (“Receivables from and equity in construction joint ventures”) in the Consolidated Balance Sheets. This method is a permissible modification of the equity method of accounting which is a common practice in the construction industry.
Cash, Cash Equivalents and Restricted Cash—Our cash and cash equivalents are comprised of highly liquid investments with original maturities of three months or less. The Company maintains its cash and cash equivalents at major financial institutions. The cash and cash equivalents balance at one or more of these financial institutions exceeds the Federal Depository Insurance Corporation (“FDIC”) insurance coverage. The Company periodically assesses the credit risk associated with these financial institutions and believes that the risk of loss is minimal. There was no
Lease Arrangements—In the ordinary course of business, the Company enters into a variety of lease arrangements, including operating and finance leases.
•Operating & Finance Leases—The Company determines if an arrangement is a lease at inception. The operating lease right-of-use (“ROU”) assets are included within the Company’s non-current assets and lease liabilities are included in current or non-current liabilities on the Company’s Consolidated Balance Sheets. Finance leases are included in “Property and equipment,” “Current maturities of long-term debt” and “Long-term debt” on the Company’s Consolidated Balance Sheets. ROU assets represent the Company’s right to use, or control the use of, a specified asset for the lease term. Lease liabilities are the Company’s obligation to make lease payments arising from a lease and are measured on a discounted basis. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term on the commencement date. The operating lease ROU asset includes any lease payments made and initial direct costs incurred and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments continues to be recognized on a straight-line basis over the lease term.
Federal and State Income Taxes—We determine deferred income tax assets and liabilities using the balance sheet method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax

rates and laws. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize the financial statement benefit of a tax position only after determining the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. As a result of the Company’s analysis, management has determined the Company has an Uncertain Tax Position (“UTP”) liability of $5,214 and an additional liability related to the UTP for penalties of $1,043 and interest of $1,225 at December 31, 2025. The Company’s policy is to recognize interest related to any underpayment of taxes as interest expense and penalties as administrative expense. Refer to Note 12 - Income Taxes for further information regarding our federal and state income taxes.
Recently Adopted Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosure” which requires companies to disclose disaggregated information about a reporting entity’s effective tax rate reconciliation, using both percentages and reporting currency amounts for specific standardized categories. Separate disclosures are required for any reconciling items that are equal to or greater than a specified quantitative threshold. The guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. This ASU affects financial statement disclosure only, and its adoption in the fourth quarter of 2025 did not impact our results of operations or financial position. See Note 12 - Income Taxes for the disclosure of the disaggregated effective tax rate reconciliation.
New Accounting Pronouncements
In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses” which requires companies to disclose disaggregated information for prescribed expense categories within relevant income statement expense line items. The guidance is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard and plans to adopt the provisions of ASU 2024-03 in fiscal year 2027. This ASU affects financial statement disclosure only, and its adoption will not affect our results of operations or financial position.
| 3. | ACQUISITIONS | ||||
CEC Acquisition
On September 1, 2025, Sterling acquired substantially all of the assets of Irving, Texas-based CEC Facilities Group, LLC, et. al. (“CEC”) (the “CEC Acquisition”). The integration of CEC, a premier electrical and mechanical specialty contractor, broadens Sterling's array of valuable E-Infrastructure services, extends the segment into the next critical phases of the project lifecycle, and creates significant opportunities to cross-sell services. The CEC Acquisition is accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. The results of CEC since the date of acquisition are included within our E-Infrastructure Solutions segment.
Purchase Consideration—Sterling completed the CEC Acquisition for a purchase price of $561,589 , detailed as follows:
| Cash consideration transferred | $ | ||||
Equity consideration transferred ( | |||||
Earn-out (2) | |||||
| Total fair value of consideration | $ | ||||
(1) Sterling’s closing stock price on August 29, 2025.
(2) The earn-out arrangement requires the Company to pay up to $80,000 based upon CEC’s achievement of certain operating income targets.
Preliminary Purchase Price Allocation—The aggregate purchase price noted above was allocated to the assets and liabilities acquired based upon their estimated fair values at the acquisition closing date, which were based, in part, upon a preliminary external appraisal and valuation of certain assets, including specifically identified intangible assets. The excess of the fair value of consideration over the preliminary estimated fair value of the net tangible and identifiable intangible assets acquired totaling $308,856 was recorded as goodwill. This goodwill represents the value of expected future earnings and cash flows, as well as the synergies created by the integration of the new business within our organization, including cross-selling opportunities to help strengthen our existing service offerings and expand our market position. The goodwill and intangibles related to the acquisition are expected to be deductible for tax purposes.

The purchase price allocation for the CEC Acquisition is preliminary. Amounts provisionally assigned to working capital, identifiable intangible assets, and certain other assets and liabilities are subject to change as we complete our valuation procedures. We expect to finalize the allocation as soon as practicable within the measurement period, which will not exceed one year from the acquisition date. Measurement‑period adjustments, if any, will be recorded in the period they are identified and may affect the amounts recognized for assets acquired, liabilities assumed, goodwill, and the intangible amortization in our results of operations. During the year ended December 31, 2025, the total consideration and purchase price allocation changed by $811 , primarily due to the finalization of the contractually required working capital and closing cash true-up adjustments.
Identifiable Intangible Assets—Intangible assets identified as part of the CEC Acquisition are reflected in the table below and are recorded at their estimated fair value, as determined by the Company’s management, based on available information which includes a preliminary valuation from external experts. The estimated useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to future cash flows.

(1) The customer relationship intangible asset was valued using the multi‑period excess earnings method (MPEEM), an income‑based approach. This method estimates the present value of the future cash flows attributable to existing customers with consideration given to estimated customer attrition rates. Significant assumptions used in the valuation included projected revenues, operating margins, a customer attrition rate of 10 %, and a discount rate reflecting the risk inherent in the projected cash flows of 13.5 %.
(2) The trade name intangible asset was valued using the relief‑from‑royalty method. Significant assumptions used in the valuation included projected revenues, an estimated royalty rate of 1.5 %, and a discount rate of 12.5 %.
Supplemental Pro Forma Information (Unaudited)—The following unaudited pro forma combined financial information (“the pro forma financial information”) gives effect to the CEC Acquisition and related events as if they occurred at the beginning of the earliest comparative period and includes adjustments to (1) include additional intangible asset amortization associated with the CEC Acquisition (approximately $9,100 annually), (2) include tax and interest impacts, and (3) include the pro forma results of CEC for the periods ended December 31, 2025 and 2024, respectively. Additionally, the supplemental pro forma earnings were adjusted to exclude approximately $5,600 of nonrecurring acquisition related costs incurred during the year ended December 31, 2025, and adjusted the year ended December 31, 2024 to include the $5,600 of acquisition related costs. This pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved had the pro forma events taken place on the dates indicated.

Remaining Performance Obligations—RPOs represent the aggregate amount of our contract transaction price related to performance obligations that are unsatisfied or partially satisfied at the end of the period. RPOs include the entire expected revenue values for joint ventures we consolidate and our proportionate value for those we proportionately consolidate. RPOs may not be indicative of future operating results. Projects included in RPOs may be canceled or modified by customers; however, the customer would be obligated to compensate the Company for work performed through the date of termination and for any applicable contractual costs for cancellations or modifications. Excluded from RPOs are potential orders under master service agreements and expected revenues under certain non-fixed price contracts. The following table presents the Company’s RPOs, by segment:

Variable Consideration
The Company has projects that it is in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with its customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to the Company’s customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is not reached, legal action will be taken. Based upon the Company’s review of the provisions of its contracts, specific costs incurred and other related evidence supporting the unapproved change orders and claims, together in some cases as necessary with the views of the Company’s outside claim consultants, the Company concluded it was appropriate to include in project price amounts of $2,900 and $4,000 , at December 31, 2025 and 2024, respectively, relating to unapproved change orders and claims. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.
Contract Estimates
Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognizes such profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials and the performance of subcontractors. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements, may result in changes in revenue and are recognized in the period in which the changes are determined. Changes in contract estimates on performance obligations satisfied or partially satisfied in previous periods resulted in net revenue increases of $168,373 , $135,344 and $58,827 for the years ended December 31, 2025, 2024 and 2023, respectively, and are included in “Operating income” on the Consolidated Statements of Operations.

Joint Ventures with a Controlling Interest—As discussed in Note 2 - Basis of Presentation and Significant Accounting Policies, we consolidate any venture that is determined to be a VIE for which we are the primary beneficiary, or which we otherwise effectively control. The equity held by the remaining owners and their portions of net income (loss) are reflected in stockholders’ equity on the Consolidated Balance Sheets line item “Noncontrolling interests” and in the Consolidated Statements of Operations line item “Net income attributable to noncontrolling interests,” respectively.
Joint Ventures with a Noncontrolling Interest—The Company accounts for unconsolidated joint ventures using a pro-rata basis in the Consolidated Statements of Operations and as a single line item (“Receivables from and equity in construction joint ventures”) in the Consolidated Balance Sheets. This method is a permissible modification of the equity method of accounting, which is a common practice in the construction industry.

The caption “Receivables from and equity in construction joint ventures” includes undistributed earnings and receivables owed to the Company. Undistributed earnings are typically released to the joint venture partners after the customer accepts the project as completed and the warranty period, if any, has passed.
Other—The use of joint ventures exposes us to a number of risks, including the risk that our partners may be unable or unwilling to provide their share of capital investment to fund the operations of the venture or complete their obligations to us, the venture, or ultimately, the customer. Differences in opinions or views among joint venture partners could also result in delayed decision-making or failure to agree on material issues, which could adversely affect the business and operations of the joint venture. In addition, agreement terms may subject us to joint and several liability for our venture partners, and the failure of our venture partners to perform their obligations could impose additional performance and financial obligations on us. The aforementioned factors could result in unanticipated costs to complete the projects, liquidated damages or contract disputes, including claims against our partners.

Goodwill
Reporting Units—The Company’s reporting units consist of its E-Infrastructure Solutions, Transportation Solutions and Building Solutions segments. Goodwill is not amortized, but instead is reviewed for impairment at least annually during the fourth quarter of each year at the reporting unit level, absent any interim indicators of impairment or other factors requiring an assessment.
Annual Impairment Assessment—For our 2025 annual impairment test we performed a qualitative assessment for our reporting units, using information as of October 1. Under current guidance, we are permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative goodwill impairment test. We determined there were no factors indicating the need to perform a quantitative goodwill impairment test and concluded that it is more likely than not the fair value of our reporting units is greater than their carrying value and thus there was no impairment to goodwill. In addition to our annual review, we assess the impairment of goodwill whenever events or changes in circumstances indicate that the carrying value of a reporting unit may be greater than fair value. Factors that could trigger an interim impairment review include, but are not limited to, significant adverse changes in the business climate which may be indicated by a decline in our market capitalization or decline in operating results.

Credit Facility—On June 5, 2025, the Company and the subsidiary guarantors entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) that provides the Company with senior secured debt financing consisting of the following (collectively, the “Credit Facility”): (i) a senior secured first lien term loan facility (the “Term Loan Facility”) in the aggregate principal amount of $300,000 and (ii) a senior secured first lien revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of up to $150,000 (with a $75,000 limit for the issuance of letters of credit and a $15,000 sublimit for swing line loans). The obligations under the Credit Facility are secured by substantially all assets of the Company and the subsidiary guarantors, subject to certain permitted liens and other customary exceptions. The Credit Facility will mature on June 5, 2028.
The Credit Agreement also includes rights to increase the Credit Facility in an amount not to exceed the greater of (a) $400,000 or (b) 100 % of the Company’s EBITDA (as such term is defined in the Amended Credit Agreement) for the four fiscal quarter period then ended for which financial statements have been delivered less the amount of any Additional Indebtedness (as defined in the Amended Credit Agreement) incurred pursuant to clause (a), plus an unlimited amount so long as the Net Leverage Ratio (as defined in the Amended Credit Agreement), after giving pro forma effect to the incurrence or issuance of such Additional Indebtedness (assuming such Additional Indebtedness is fully drawn) and the application of proceeds therefrom and any other transaction in connection therewith, but without netting the proceeds of such Additional Indebtedness when calculating the Total Net Leverage Ratio, is less than or equal to 2 :00 to 1:00 as of the date of the four fiscal quarter period then ended for which financial statements are available.
The Credit Agreement contains various affirmative and negative covenants that may, subject to certain exceptions, restrict the ability of us and our subsidiaries to, among other things, grant liens, incur additional indebtedness, make loans, advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, purchase, redeem or otherwise acquire or retire capital stock or other equity interests, or merge or consolidate with any other person, among various other things. In addition, the Company is required to maintain the following financial covenants:
•a Total Net Leverage Ratio (as defined in the Credit Agreement) at the last day of each fiscal quarter not to be greater than 3.00 to 1.00; provided that as long as there is no event of default at such time or would result therefrom, not more

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
than twice during the term of the Credit Facility, the Company may elect a “covenant holiday” to increase the Total Leverage Ratio to be not greater than 3.50 to 1.00 for a period of four consecutive fiscal quarters in connection with a permitted acquisition in excess of $100,000 occurring during the first quarter of such period; provided further that there must be a two-quarter break between covenant holidays; and
•an Interest Coverage Ratio (as defined in the Credit Agreement) of not less than 3.00 to 1.00 as of the last day of each fiscal quarter of the Company.
As specified in the Credit Agreement, the loans under the Credit Facility bear interest at a base rate or the Secured Overnight Financing Rate (“SOFR”) plus an applicable margin based on the Total Net Leverage Ratio, at the Company’s election. At December 31, 2025, the Company calculated interest using a SOFR rate of 3.77 % and an applicable margin of 1.25 % per annum, and had a weighted average interest rate of approximately 5.56 % per annum for the year ended December 31, 2025. Scheduled principal payments on the Term Loan Facility are made quarterly and total approximately $15,000 , $15,000 and $3,750 for the years ending 2026, 2027 and 2028, respectively. A final payment of all principal and interest then outstanding on the Term Loan Facility is due on June 5, 2028. During 2025, the Company made term loan payments of $24,688 . Repayments under the Term Loan Facility may not be reborrowed under the terms of the Credit Agreement.
In addition to interest on debt borrowings, we are assessed quarterly commitment fees on the unutilized portion of the Revolving Credit Facility as well as letter of credit fees on outstanding instruments. At December 31, 2025, we had no outstanding borrowings under the $150,000 Revolving Credit Facility. Borrowings under the Revolving Credit Facility may be repaid and reborrowed under the terms of the Credit Agreement.
Debt Issuance Costs—The Company incurred $1,409 of fees relating to the amendment and restatement of the Credit Facility in the second quarter of 2025. The costs associated with the Credit Facility are reflected on the Consolidated Balance Sheets as a direct reduction from the related debt liability and amortized over the term of the facility. Amortization of debt issuance costs was $997 , $1,344 and $2,026 for the years ended December 31, 2025, 2024 and 2023, respectively, and was recorded as interest expense.
Compliance and Other—As of December 31, 2025, we were in compliance with all of our restrictive and financial covenants. The Company’s debt is recorded at its carrying amount in the Consolidated Balance Sheets. Based upon the current market rates for debt with similar credit risk and maturities, at December 31, 2025 and 2024, the fair value of our debt outstanding approximated the carrying value, as interest is based on Term SOFR plus an applicable margin.

Insurance
The Company is required by its insurance providers to obtain and hold standby letters of credit. These letters of credit serve as a guarantee by the banking institution to pay the Company’s insurance providers the incurred claim costs attributable to its general liability, workers’ compensation and automobile liability claims, up to the amount stated in the standby letters of credit, in the event that these claims were not paid by the Company.
Property and Casualty—The Company has moved to a three-year Structured Reinsurance Program for Workers’ Compensation, General Liability and Auto Liability, which is subject to a $1,000 deductible per occurrence, followed by an umbrella program (Workers’ Compensation, General Liability and Auto Liability) that is subject to a corridor deductible of $9,000 . Sterling is responsible for the first $9,000 of losses over the three-year program. The program aggregate is indexed to payroll and may fluctuate up or down depending upon actual exposure. We accrue for probable losses, both reported and unreported, that are reasonably estimable using actuarial methods based on historic trends, modified, if necessary, by recent events. Changes in our loss assumptions caused by changes in actual experience would affect our assessment of the ultimate liability and could have an effect on our operating results and financial position. The Company also maintains commercial insurance coverage in excess of the limits of our primary and umbrella commercial automobile, general liability and employers’ liability policies, in the amount of $70,000 .
Medical—The Company maintains fully insured and self-insured medical benefit plans, which provide medical benefits to employees electing coverage under the plans. Under its self-insured plans, the Company has stop-loss coverage per claim to limit the exposure arising from these claims. Self-insured claims filed and claims incurred but not reported are accrued based upon management’s estimates of the ultimate cost of claims incurred using actuarial assumptions followed in the insurance industry and historical experience. Although management believes it has the ability to reasonably estimate losses related to claims, it is possible that actual results could differ from recorded self-insured liabilities.
Guarantees
The Company obtains bonding on construction contracts primarily through Travelers Casualty and Surety Company of America (“Travelers”). As is customary in the construction industry, the Company indemnifies Travelers for any losses incurred by it in connection with bonds that are issued. The Company has granted Travelers a security interest in accounts receivable and contract rights for that obligation.
On certain projects, the Company issues performance guarantees for the remaining cost of work to be performed. For lump-sum contracts, the performance guarantee amount is the cost to complete the contracted work, less amounts remaining to be billed to the client under the contract. Remaining billable amounts could be greater or less than the cost to complete. In those cases where costs exceed the remaining amount billable under the contract, we may have recourse to third parties, such as owners, partners, subcontractors or vendors for claims.
The Company typically indemnifies contract owners for claims arising during the construction process and carries insurance coverage for such claims, which in the past have not been material.
The Company’s Certificate of Incorporation provides for indemnification of its officers and directors. The Company has a directors and officers insurance policy that limits their exposure to litigation against them in their capacities as such.
Litigation
The Company, including its construction joint ventures and its 50 % owned subsidiary, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. Management, after consultation with legal counsel, does not believe that the outcome of these actions will have a material impact on the Consolidated Financial Statements of the Company. As of December 31, 2025, the Company is not aware of any pending legal proceedings that are expected to result in a material loss.
Purchase Commitments
To manage the risk of changes in material prices and subcontracting costs used in tendering bids for construction contracts, most of the time, we obtain firm quotations from suppliers and subcontractors before submitting a bid. These quotations do not include any quantity guarantees. As soon as we are advised that our bid is the lowest, we enter into firm contracts with most of our materials suppliers and sub-contractors, thereby mitigating the risk of future price variations affecting the contract costs.

| 13. | STOCKHOLDERS' EQUITY | ||||
General—Holders of common stock are entitled to one vote for each share on all matters voted upon by the stockholders, including the election of directors, and do not have cumulative voting rights. Holders of common stock are entitled to share ratably in net assets upon any dissolution or liquidation after payment of provision for all liabilities and any preferential liquidation rights of our preferred stock then outstanding. Common stock shares are not subject to any redemption provisions and are not convertible into any other shares of capital stock. The rights, preferences and privileges of holders of common stock are subject to those of the holders of any shares of preferred stock that may be issued in the future.
The Board of Directors may authorize the issuance of one or more classes or series of preferred stock without stockholder approval and may establish the voting powers, designations, preferences and rights and restrictions of such shares. No preferred shares have been issued.
Stock Repurchase Program—On December 5, 2023, the Board of Directors approved a stock repurchase program authorizing the repurchase of up to $200,000 of the Company’s common stock. Effective November 12, 2025, the Board of Directors authorized a new stock repurchase program, permitting the repurchase of up to $400,000 of the Company’s outstanding common stock over the following 24 months. This new authorization supersedes and replaces the Company’s prior repurchase program, which had been scheduled to remain in effect through December 5, 2025 and had approximately $81,000 of remaining capacity at the time it was replaced. The new stock repurchase program expires on November 12, 2027 and may be modified, extended or terminated by the Board of Directors at any time.

| 14. | STOCK INCENTIVE PLAN AND OTHER EQUITY ACTIVITY | ||||
General—The Company has a stock incentive plan (the “Stock Incentive Plan”) and an employee stock purchase plan (the “ESPP”) that are administered by the Compensation and Talent Development Committee of the Board of Directors. Under the Stock Incentive Plan, the Company can issue shares to employees and directors in the form of restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and performance share units (“PSUs”). Compensation expense recognized related to the Company’s Stock Incentive Plan was $22,411 , $17,870 and $12,426 for 2025, 2024 and 2023, respectively. Under the Stock Incentive Plan, we are authorized to issue 5,300 shares, and assuming PSU vestings occur at maximum payout, 1,364 authorized shares remained available under our Stock Incentive Plan for future grants at December 31, 2025.
Under the ESPP, employees may make quarterly purchases of shares at a discount through regular payroll deductions for up to 15 % of their compensation, subject to a $25 fair market value maximum purchase per year. The shares are purchased at 85 % of the closing price per share on the last trading day of the calendar quarter. Included within total stock-based compensation expense is $355 , $258 and $181 of expense related to the ESPP, for 2025, 2024 and 2023, respectively. ESPP expense represents the difference between the fair value on the date of purchase and the price paid. The Company issued 11 , 13 and 18 shares related to the ESPP in 2025, 2024 and 2023, respectively. At December 31, 2025, 649 authorized shares remained available for issuance under the ESPP.
Total equity-based compensation expense recognized related to the Company’s Stock Incentive Plan and the ESPP was $22,766 , $18,128 and $12,607 for 2025, 2024 and 2023, respectively, primarily recognized within general and administrative expenses. At December 31, 2025, there was approximately $24,300 of unrecognized compensation cost related to equity-based grants, which is expected to be recognized over a weighted-average period of 1.5 years. The Company recognizes forfeitures as they occur, rather than estimating expected forfeitures.
We receive a tax deduction upon the vesting of RSUs and performance based shares for the price of the shares at the date of vesting. Our total recognized tax benefit based on our compensation expense was $21,000 , $33,100 and $12,200 for 2025, 2024 and 2023, respectively.

Stock Performance-Based Awards—The Company has stock performance-based awards that are based upon the Company’s stock price performance relative to industry peers and cliff vest at the end of three years . The total initial fair value for these awards is determined based upon a Monte Carlo simulation value at the grant date applied to the total number of granted target shares. This fair value is expensed ratably over the vesting period, and during 2025, the Company recognized $1,200 of compensation expense. During 2025, 8 shares of this award type were granted with a weighted-average grant-date fair value per share of $235.99 , that was based upon a risk-free interest rate of 4.18 % an expected dividend yield of zero , historical volatility of 46.1 %, and a remaining performance period of 3 years.

Defined Contribution Plans
The Company maintains a defined contribution profit-sharing plan (401(k) plan) covering substantially all non-union persons employed by the Company, whereby employees may contribute a percentage of compensation, limited to maximum allowed amounts under the Internal Revenue Code. The 401(k) plan provides for a discretionary employer contribution and is determined annually by the Company’s board of directors. The Company made matching contributions of $4,585 , $3,839 and $3,346 , respectively, for the years ended December 31, 2025, 2024 and 2023.
Multi-Employer Pension Plans
As of December 31, 2025, the Company had approximately 4,400 employees, including 3,300 field personnel. We had 200 employees, or approximately 4 % of total employees, that were union members covered by collective bargaining agreements.
The Company contributes to a number of multi-employer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees. The risks of participating in these multi-employer plans are different from single-employer plans in the following aspects:
•Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
•If the Company chooses to stop participating in some of its multi-employer plans, the Company may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

| 19. | RELATED PARTY TRANSACTIONS | ||||
The Company has a limited number of related party transactions. The most significant transactions relate to property leases with the management of certain subsidiaries who own or have an ownership interest in real estate and other companies. The leases are for office space, equipment yards or maintenance shops and have an annual cost of approximately $4,000 . The leases expire at various points over the next to eight years . At December 31, 2024, the Company had a receivable from RHB of approximately $32,100 , of which approximately $25,800 was for certain RHB operating costs paid on its behalf and approximately $6,300 was for undistributed earnings of RHB. The Company collected the entire December 31, 2024 receivable balance in the first quarter of 2025. During the twelve months ended December 31, 2025, the Company has performed work for and received services from entities owned or partially owned by the management of certain subsidiaries. For the work performed, the Company earned approximately $9,700 in revenue, and for the services received, incurred approximately $440 of expense for the twelve months ended December 31, 2025.
In connection with the CEC acquisition, the Company recorded a payable to the sellers, some of whom are now related parties, that is directly linked to a project‑specific receivable of approximately $15,800 owed to CEC as of the acquisition date. Consistent with the closing settlement mechanics, amounts received from the customer on this receivable will be remitted to the sellers and, accordingly, the Company recognized a liability for the expected remittance. The arrangement does not impact gross profit, as the payable represents a pass‑through of cash collected on a pre‑close balance rather than consideration for post‑close performance. The asset and liability are presented within other current assets and liabilities, respectively, given the expected collection and remittance timeframe of less than 12 months.
| 20. | SEGMENT INFORMATION | ||||
The Company’s internal and public segment reporting are aligned based upon the services offered by its operating segments. The Company’s operations consist of three reportable segments: E-Infrastructure Solutions, Transportation Solutions and Building Solutions. The segment information for the prior periods presented has been recast to conform to the current presentation. The Company’s CODM, which is the Company’s Chief Executive Officer, uses both segment gross profit and operating income for each segment predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances of both profit measures when making decisions about allocating capital and personnel to the segments. We incur certain expenses at the corporate level that relate to our business as a whole. A portion of these expenses are allocated to our business segments by various methods, but primarily on the basis of usage. The balance of the corporate level expenses are reported in the “Corporate G&A Expense” line, which is primarily comprised of corporate headquarters facility expense, the cost of the executive management team, and other expenses pertaining to certain centralized functions that benefit the entire Company but are not directly attributable to any specific business segment, such as corporate human resources, legal, governance, compliance and finance functions. Total assets held at Corporate primarily include cash and prepaid assets.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None.
Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures include, but are not limited to, controls and other procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to the issuer’s management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
The Company’s principal executive officer and principal financial officer reviewed and evaluated the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of December 31, 2025. During the year ended December 31, 2025, the Company acquired Drake and CEC Facilities, and, as permitted by SEC guidance for newly acquired businesses, the scope of management’s assessment of our disclosure controls and procedures as of December 31, 2025 did not include the disclosure controls and procedures, to the extent that are subsumed by internal control over financial reporting, of Drake and CEC Facilities, whose financial statements, in the aggregate, reflect total assets and revenues constituting 30% and 9%, respectively, of the related Consolidated Financial Statements of the Company as of December 31, 2025. Based on that evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective at December 31, 2025.
Management’s Report on Internal Control over Financial Reporting
The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of our assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.
Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and
65
compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting can also be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.
Management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, management used the criteria described in 2013 Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. As permitted by SEC guidance, the scope of management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2025 did not include internal control over financial reporting for Drake and CEC Facilities, whose financial statements, in the aggregate, reflect total assets and revenues constituting 30% and 9%, respectively, of the related Consolidated Financial Statements of the Company as of and for the year ended December 31, 2025. Management will include these acquired businesses in the scope of its assessment of internal control over financial reporting beginning in 2026. Based on this assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2025.
Attestation Report of the Registered Public Accounting Firm
Grant Thornton LLP, the independent registered public accounting firm that audited our Consolidated Financial Statements included in this annual report on Form 10-K, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, included in Item 8 of Part II of this report under the heading “Reports of the Company’s Independent Registered Public Accounting Firm.”
Changes in Internal Control over Financial Reporting
Based on the most recent evaluation, we have concluded that no changes in our internal control over financial reporting occurred during the three months ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls
Internal control over financial reporting may not prevent or detect all errors and all fraud. Also, projections of any evaluation of effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
