MATRIX SERVICE CO (MTRX) Business

Item 1.    Business

BUSINESS

We began operations in 1984 as an Oklahoma corporation under the name of Matrix Service. In 1989, we incorporated in the State of Delaware under the name of Matrix Service Company, and in 1990 we began trading on the NASDAQ exchange. We provide engineering, fabrication, construction, and maintenance services to support critical energy infrastructure and industrial markets. We maintain regional offices throughout the United States, Canada and other international locations, and operate through separate union and non-union subsidiaries.

Our principal executive offices are located at 15333 JFK Blvd., Ste. 400, Houston, TX, 77032. Unless the context otherwise requires, all references herein to “Matrix Service Company”, “Matrix”, the “Company” or to “we”, “our”, and “us” are to Matrix Service Company and its subsidiaries.

Our purpose is to create long-term value for our employees, business partners, shareholders and communities. We are committed to fulfilling our purpose by striving to be a profitable, innovative, and growth-oriented company of choice for engineering, constructing, and maintaining essential energy and industrial infrastructure that delivers its services safely, with high quality, and on time, resulting in strong customer relationships.

Through our zero-incident safety culture, commitment to execution excellence and highly skilled workforce, we share one goal: to deliver the best to our customers, shareholders, employees and people across the globe who rely on the infrastructure we help design, build and maintain.

OTHER BUSINESS MATTERS

Customers and Marketing

We provided services to approximately 232 customers in fiscal 2026. Most of our revenue comes from long-term customer relationships. One customer accounted for $176.4 million or 20.1% of our consolidated revenue in fiscal 2026, which was primarily included in the Storage and Terminal Solutions segment. Another customer accounted for $153.1 million or 17.5% of our consolidated revenue in fiscal 2026, which was primarily included in the Utility and Power Infrastructure segment. Another customer accounted for $88.1 million or 10.0% of our consolidated revenue in fiscal 2026, which was primarily included in the Storage and Terminal Solutions segment. Because these significant customers generally contract with us for specific projects or for specific periods of time, we may lose these customers from year to year as the projects or maintenance contracts are

completed. See Part II, Item 8. Financial Statements and Supplementary Data, Note 13 - Segment Information, for more information about concentration of revenue by segment.

We market our services and products primarily through our marketing and business development personnel, senior professional staff and our operating management. We competitively bid most of our projects; however, we have a number of preferred provider relationships with customers who award us work through long-term agreements. Our projects have durations ranging from a few days to multiple years.

Types of Contracts

We perform work for our customers under contracts with various compensation formats that include fixed-price, time-and-material, cost-plus, or some combination thereof. Fixed-price contracts cover a defined scope of services for a fixed amount. Time-and-material contracts generally allow services to be provided for agreed-upon hourly rates for labor and reimbursement of the costs of certain materials and equipment, plus fees. Cost-plus contracts provide for reimbursement of the actual costs to perform work plus fees. Fixed-price contracts typically present opportunities for higher margins, but carry a greater risk in terms of profitability because cost overruns may not be recoverable. Time-and-material and cost-plus contracts generally have lower margins, but carry a lower risk of cost overruns. Time-and-material and cost-plus contracts may also include not-to-exceed provisions that impose risk on cost recovery and profitability, or target price and other performance provisions that provide opportunity and risk on profitability.

A significant amount of our work is performed under contracts for specific projects on a fixed-price basis. While we act as the prime contractor of full engineering, procurement, and construction ("EPC") scopes on many of our projects, we also execute a variety of contract scopes under various project delivery methods implemented by our customers, including but not limited to front-end engineering and design contracts, standalone engineering contracts, standalone fabrication contracts, standalone construction contracts, or some combination thereof, as well as acting as a subcontractor to prime contractors for various scopes.

The Company also performs work under Master Service Agreements (“MSAs”), which allow us to provide more routine services to our customers on an as-needed basis, including but not limited to maintenance and repair services, typically priced using a time-and-material or cost-plus basis.

Insurance

We maintain a comprehensive schedule of primary and excess insurance policies covering a broad range of exposures arising from our construction and general business operations. All of our policies have been procured with limits and deductibles or self-insured retention amounts up to certain limits applied on an occurrence or claims made basis.

Typically our contracts require us to indemnify our customers for injury, damage or loss arising from the performance of our services and provide warranties for materials. We may also be required to name the customer as an additional insured up to the limits of insurance available, to purchase special insurance policies for specific projects. We generally require our subcontractors to indemnify us and our customers and name us as an additional insured for activities arising out of the subcontractors’ work. There can be no assurance that our insurance and the additional insurance coverage provided by our subcontractors will fully protect us against a valid claim or loss under the contracts with our customers and subcontractors.

Bonding

In connection with our business, we may be required to provide various types of surety bonds guaranteeing our performance under certain contracts. Our ability to obtain surety bonds depends upon the surety company’s current underwriting standards. Customers may also request us to provide letters of credit in lieu of bonds to satisfy performance and financial guarantees on some projects. We also require certain subcontractors to provide additional security, including surety bonds in favor of us, to secure the subcontractors' work.

Competition

We compete with local, regional, national and international contractors and service providers. Competitors vary with the markets we serve. Few competitors compete in all of the markets we serve or provide all of the services we provide. Contracts are generally awarded based on price, quality, safety performance, schedule, experience and customer satisfaction.

Seasonality and Other Factors

Our operating results can exhibit seasonal fluctuations for a variety of reasons. In our Process and Industrial Facilities segment, turnarounds and planned outages at customer facilities are typically scheduled in the spring and the fall when the demand for

energy is lower. Therefore, revenue volume for turnaround and maintenance work can be higher during the spring and fall than other periods throughout the year. Within the Utility and Power Infrastructure segment, power delivery work is generally scheduled by the public utilities when the demand for electricity is at its lowest. Therefore, revenue volume for power delivery work is typically lower in the summer months than in other periods throughout the year.

Our business can also be affected, both positively and negatively, by seasonal factors such as energy demand or weather conditions including hurricanes, snowstorms, and abnormally low or high temperatures. Some of these seasonal factors may cause some of our offices and projects to close or reduce activities temporarily. In addition to the above noted factors, the general timing of project starts and completions could exhibit significant fluctuations.

Other factors impacting operating results in all segments come from decreased work volume during holidays, work site permitting delays or customers accelerating or postponing work. The differing types, sizes, and durations of our contracts, combined with their geographic diversity and stages of completion, often result in fluctuations in our operating results.

Our overhead cost structure is generally fixed in the short term. Significant fluctuations in revenue volume usually lead to over or under recovery of fixed overhead costs, which can have a material impact on our gross margin and profitability.

Material Sources and Availability

We depend on the availability of certain equipment and materials for our projects, including, but not limited to, structural steel, steel piping, rebar, valves, copper, electrical components, fabricated products and equipment, and delivery freight. A number of factors that we may not be able to predict or control could result in increased costs for, or delays in delivery of, this equipment or materials, including supply chain or other logistical challenges. Global trade relationships and other general market and political conditions could also impact production, delivery or pricing of such equipment or materials (e.g., inflation, interest rates, recessionary economic conditions, and tariffs). We have been proactive with managing our procurement processes to help reduce the impacts of these factors on our business and to help ensure we continue to have the equipment and materials we need available. Rising prices and the potential for equipment and materials shortages have created additional risk in bidding and executing work profitably. See Item 1A. Risk Factors, Risks Related to our Business and Operations, for more information.

Human Capital Management

Employees

Successful execution of our business strategy is dependent on attracting, developing, and retaining key employees who represent our core values and the communities we serve. Our people are our greatest resource. Since 2016, we have been certified as a Great Place To Work®, both a point of pride and an invaluable tool for continuous improvement supporting our objective of remaining an employer of choice.

Given the nature of our work, the size of our employee population can vary significantly throughout the year because of the number, type, and size of projects we have in progress at any particular time. As of June 30, 2026, we had 2,370 employees worldwide. Of those employees, 552 were employed in office-based positions and 1,818 were employed in field or craft positions. The location of our employees was as follows:

The percentage of our employees represented by trade unions as of June 30, 2026, was approximately 26%. Operating under collective bargaining agreements with various unions, our union employees are provided with benefits including health and welfare, pension, training programs and competitive compensation plans. We have not experienced any strikes or work stoppages in recent years and are proud that our relationships with our employees and labor unions are strong.

Business Ethics and Core Values

Our success relies on the skills, experience and dedication of our employees. We are committed to cultivating an engaging and dynamic work environment where people can find opportunities to succeed, grow and contribute to the success of the company. Our employees work each day to provide safe and reliable services to a wide range of customers in the states where we operate. Our core values, listed below, guide our employee behaviors and the ways in which we conduct our business and operations.

•Commitment to Safety

•Integrity

•Positive Relationships

•Stewardship

•Community Involvement

•Deliver the Best

Our employees are entrusted with engineering, constructing, and maintaining the complex, critical infrastructure that supports modern daily living and quality of life. Ethics and integrity are foundational in our ability to be successful and are engrained in our culture and core values. Across all areas of our business, we maintain focus on compliance and doing the right thing, and integrity is essential to every aspect of our business, in both policy and practice. Accordingly, we are committed to fostering compliance with all applicable laws and regulations, and to upholding the highest standards of ethical conduct in accordance with our code of conduct.

Health and Safety

We maintain a comprehensive safety and risk management program. Our senior leadership, risk management department, and large network of safety directors and health, safety, and environmental professionals, effectively assess and manage potential risks and liabilities throughout the pre-construction and performance phases of our projects. Ensuring the safety of our employees and those around us is integral to who we are, and paramount to our success and sustainability. The journey to achieving and maintaining a zero-incident safety performance requires a strong culture of safety and hands-on leadership, combined with robust training along with comprehensive policies, processes, and systems to plan, perform, report, measure, and review, and to continuously improve our performance. We have incorporated safety as a key performance metric in our incentive compensation plan. We track and maintain several key safety metrics, which management reviews monthly. One such metric is our Total Recordable Incident Rate (‘‘TRIR’’), which is calculated by multiplying the number of recordable incidents by 200,000 and dividing that number by the total hours worked each year. Our TRIR was 0.92, 0.51, and 0.91 during fiscal years 2026, 2025, and 2024, respectively. Another metric is our Days Away, Restricted, or Transferred Rate ("DART"), which is calculated by multiplying the number of incidents requiring days away, restricted, or transferred by 200,000 and dividing that number by the total hours worked each year. Our DART was 0.33, 0.21, and 0.28 during fiscal years 2026, 2025, and 2024, respectively. These metrics are also used by others in our industry, which allows for a more objective comparison of our performance.

Culture and Engagement

Foundational to attracting, developing, and retaining an engaged workforce is our commitment to making sure our employees feel safe, know they are valued, know that their work matters, and are provided opportunities to achieve their maximum potential. We believe when we foster a respectful and collaborative workplace culture, we create an environment where employees are empowered to do their best work and feel connected to our shared success.

We continued to advance and strengthen our culture by proactively addressing mental health issues through our enterprise-wide Mental Health Task Force, Matrix C.A.R.E.S. In an industry where the suicide rate is four times the national average, we are committed to raising awareness and eliminating stigma around mental health and making resources available to all employees to address mental health issues or crises. Through targeted job site and virtual sessions, Matrix C.A.R.E.S. reached field and craft employees across the company, as well as our office-based employees across North America. We also embedded the importance of mental health into daily operations as a key part of our safety orientations and onboarding for craft and field employees. This consistent communication demonstrates our commitment to making mental health support accessible to all employees, everywhere.

Total Rewards Package

As part of our compensation philosophy and to attract and retain superior talent, we seek to offer and maintain market-competitive total rewards programs for our employees. In addition to base salaries, additional programs include incentive and project bonus opportunities, comprehensive healthcare coverage and insurance benefits, Company matched retirement plans, health savings and flexible spending accounts, an Employee Stock Purchase Plan, paid holidays and other paid time off, family leave, and flexible work schedules where possible. Other offerings include employee assistance programs with 365/24/7 access to resources and support, and Matrix HealthMatters, our robust wellness program that provides resources and education to help employees and their families get and stay healthy, focusing holistically on physical, mental and financial health.

Training and Employee Development Programs

Investment in continuous learning is essential to providing industry-leading expertise and service to our clients, continuous improvement across our organization, and meaningful career development opportunities for our people. From in-person to online courses, formalized and other specialized training, our employees benefit from opportunities to strengthen their leadership and management competencies, improve communication and interpersonal skills, and advance their technical proficiency. Through Matrix University, our people have access to resources that include a robust Learning Management System (LMS) that provides enterprise-wide access for employees to a number of online learning modules and support tools.

Our employees also benefit from the Matrix Performance Development Program, designed for collaborative development of annual performance goals and to promote continuous, transparent feedback between employees and their supervisors.

Giving Back

We also empower our employees to donate time, talent, and resources through Company-led initiatives, matching of employee charitable contributions, and paid volunteer time off. Each year, our employees collectively log thousands of hours participating in individual community service projects in addition to hours they invest serving on non-profit boards and participating in Company-sponsored charitable events. We also provide direct corporate financial support to non-profit organizations in the communities where we live and work.

Patents and Proprietary Technology

Our subsidiaries have several patents and continue to pursue new ideas and innovations to better serve our customers in several areas of our business. The Flex-A-Span® and Flex-A-Seal® trademarks are utilized to market our unique seals for floating roof tanks. The Flowdome® trademark is used to market our geodesic dome tank roofs. Our SwingMaster® trademark is used to market our central type swing joints. The patent for the Training Tank for Personnel Entry, Exit and Rescue relates to a training device that can be used to train personnel on equipment that is made to simulate confined space scenarios. We hold two separate patents for Pipe Lifting and Orienting Apparatus and Method that is used to raise and lower pipes and to move them around the upper surface of floating roof of tanks. The Batten Joint for an Internal Floating Roof of a Fluid Tank allows us to overcome many of the disadvantages associated with other types of joints used for internal floating roofs for floating tanks.

We also hold a perpetual license to use various patents and technologies related to LNG storage tanks, liquid nitrogen/liquid oxygen storage tanks, liquid petroleum gas storage tanks and thermal vacuum chambers.

While our intellectual property is not our main business, we believe that the ability to use these patents, trademarks, and technology enables us to expand our presence in the markets we serve and minimizes the development costs typically associated with organic growth.

Commission. Regulations promulgated by these agencies require employers and independent contractors to implement work practices, medical surveillance systems and personnel protection programs to protect employees from workplace hazards and exposure to hazardous chemicals and materials. In recognition of the potential for accidents within various scopes of work, these agencies have enacted strict and comprehensive safety regulations. We have established and consistently reinforce and monitor compliance with comprehensive programs intended to ensure that we comply with all applicable health and safety regulations to protect the safety of our workers, subcontractors and customers. While we believe that we operate safely and prudently, there can be no assurance that accidents will not occur or that we will not incur substantial liability in connection with the operation of our businesses. In order to minimize the financial exposure resulting from potential accidents associated with our work, we maintain liability insurance to limit losses that could result from our work.

We are subject to labor laws and, where applicable, regulations associated with collective bargaining agreements and prevailing wage requirements. While we work to adhere to the Fair Labor Standards Act (FLSA) and state level laws and regulations that establish minimum wage, overtime pay, and other employment standards, the inherent nature of work in the construction industry carries risk of claims for noncompliance.

Across our organization, from our project sites to our offices, we are committed to environmental stewardship and to continuously striving to perform our work in a sustainable and environmentally responsible manner.

Our operations and the operations of our customers are subject to extensive and changing environmental laws and regulations. These laws and regulations relate primarily to air and water pollutants and the management and disposal of hazardous materials. We are exposed to potential liability for personal injury or property damage caused by any release, spill, exposure or other accident involving such pollutants, substances or hazardous materials.

We are subject to numerous environmental laws, regulations and programs with respect to our work, including but not limited to the handling, transportation and disposal of non-hazardous and hazardous substances and wastes, laws governing emissions and discharges into the environment, including discharges into air, surface water, groundwater and soil, and programs related to the protection of endangered species and critical habitats. In order to limit the risks associated with environmental exposure, we maintain certain environmental insurance policies that cover liability that may be incurred as a result of accidental releases of hazardous materials. We do not currently foresee any significant future capital spending relating to environmental matters.

In order to limit costs incurred as a result of environmental exposure, we maintain contractor’s pollution liability insurance that covers liability that may be incurred as a result of accidental releases of hazardous materials.

We do not currently foresee any significant future capital spending relating to environmental matters.
