Rhea-AI Filing Summary

Trex Company, Inc. files its annual report detailing a leading position in composite decking and railing, with products made largely from recycled wood fibers and polyethylene. Net sales reached $1.17 billion, up 2%, while net income fell to $190.4 million, down 20.1%, and diluted EPS declined to $1.78.

The company is investing heavily for growth and efficiency, including $233.6 million of 2025 capital spending, largely on a new Arkansas manufacturing campus expected to begin decking production in 2027. Trex emphasizes brand strength, broad distribution through wholesale channels plus Home Depot and Lowe’s, and a strong sustainability story as one of North America’s largest recyclers of polyethylene film.

Key risks include reliance on a small number of major customers that account for most sales, exposure to housing and home‑improvement cycles, weather‑driven seasonality, inflationary and raw material pressures, and potential cybersecurity, climate, labor, and financing challenges. The company also continues to repurchase shares, buying about 1.53 million shares in the fourth quarter under its ongoing stock repurchase program.

Positive

None.

Negative

Profitability weakened despite higher sales: 2025 net sales rose 2.0% to $1.17 billion, but net income declined 20.1% to $190.4 million and EBITDA decreased 14.8% to $320.9 million, signaling margin compression and higher operating burden.

Insights

Sales were roughly flat, but profit compression and heavy capex shift the risk profile.

Trex grew net sales modestly to $1.17 billion, yet net income dropped 20.1% to $190.4 million and EBITDA fell 14.8% to $320.9 million. This indicates margin pressure despite scale and a strong brand in composite decking and outdoor living products.

The company is deploying substantial capital, spending $233.6 million in 2025, including $167.8 million on its new Arkansas facility and additional amounts on safety, ERP and capacity upgrades. These outlays aim to support future growth but weigh on near‑term free cash flow and raise execution and utilization risk.

Risk disclosures highlight dependence on a few major customers, raw material and transportation costs, seasonality, and broader macro factors such as inflation, housing activity, climate and cybersecurity. Investors will likely focus on whether new capacity, cost‑reduction projects and product innovation restore EBITDA growth in periods after 2025 as demand and mix evolve.

	aesthetics that raise the bar for beauty and performance and is available in hues inspired by stunning natural settings. Trex Transcend Lineage cladding is available in six luxurious on trend hues. Trex Transcend cladding is available in six multi-tonal monochromatic classical earth tones and premium tropical colors.

Trex products offer a number of significant aesthetic advantages over wood while eliminating many of wood’s major functional disadvantages, which include warping, splitting, and other damage from moisture. In addition to resisting fading and surface staining, Trex products require no sanding, staining, or sealing, resist moisture damage, provide a splinter-free surface and do not require chemical treatment against rot or insect infestation. Special characteristics (including resistance to splitting, the ability to bend, and ease and consistency of machining and finishing) facilitate installation, reduce contractor call-backs, and afford consumers a wide range of design options. Combined, these aspects yield significant aesthetic advantages and lower maintenance than wood decking and railing and ultimately render Trex products less costly than wood over the life of the deck.

We have received product building code listings from the major U.S. building code listing agencies for decking and railing and from the major Canadian building code listing agency for decking. The listings facilitate the acquisition of building permits by deck builders and promote consumer and industry acceptance of our products as an alternative to wood decking.

Customers and Distribution

We are committed to conducting business activities with the highest standards of business ethics and in accordance with all applicable laws and regulations. Our Vendor and Customer Code of Conduct and Ethics (Code), available at www.trex.com/our-company, applies to all parties providing goods and services to the Company, and all channel partners who distribute, sell and/or install our products (collectively, Business Partners). We expect all Business Partners, and all of their employees, agents and subcontractors to follow our high ethical standards set forth in the Code while they are conducting business with us or on our behalf. In addition, we expect our Business Partners to understand and comply with the Trex Company Code of Conduct and Ethics, available at www.trex.com/our-company, to do business with Business Partners who share the same commitment to human rights that we have and as set forth in our Human Rights Policy, available at www.trex.com/our-company.

Wholesale Distributors/Retail Lumber Dealers. We generate most of our sales for our composite decking and railing products through our wholesale distribution network by selling Trex products to wholesale distributors, who in turn, sell our products to retail lumber outlets. These retail dealers market to both homeowners and contractors, but they emphasize sales to professional contractors, remodelers, and homebuilders. Contractor-installed decks generally are larger installations with professional craftsmanship. Our retail dealers generally provide sales personnel trained in Trex products, contractor training, inventory commitment, and point-of-sale display support. We believe that attracting wholesale distributors, who are committed to our products and marketing approach and can effectively sell higher value products to contractor-oriented lumber yards and other retail outlets, is important to our future growth. Our distributors provide value-added service in marketing our products because they sell premium wood decking products and other innovative building materials that typically require product training and personal selling efforts. We typically appoint two to three distributors within a specified area to sell only Trex decking products on an exclusive basis. The distributor purchases our products at prices in effect at the time we ship the product to the distributor.

Home Centers. We sell our products through Home Depot and Lowe’s stores. Home Depot and Lowe’s purchase products directly from us for stocking on their shelves. They also purchase product through our wholesale distributors for special orders placed by consumers. Home Depot and Lowe’s serve both the contractor market and the “do-it-yourself” market. We believe that brand exposure through Home Depot and Lowe’s promotes consumer acceptance of our products.

For the years ended December 31, 2025, 2024, and 2023, three customers represented approximately 73%, 81%, and 72%, respectively, of the Company’s total net sales. No other customer represented 10% or more of the Company’s total net sales.

Manufacturing Process

Products manufactured at our facilities in Virginia and Nevada are primarily manufactured from reclaimed wood fiber and scrap polyethylene. Our primary manufacturing process for the products involves mixing wood particles with plastic, heating and then extruding, or forcing, the highly viscous and abrasive material through a profile die. We use many proprietary and skill-based advantages in our eco-friendly manufacturing process. We use Six Sigma and Lean Manufacturing methodologies throughout our Company within our plant operations and in the planning and execution of certain projects.

Our manufacturing processes require significant capital investment, expertise, and time to develop. We have continuously invested the capital necessary to expand our manufacturing throughput and improve our manufacturing processes.

In October 2021, the Company announced plans to add a third manufacturing facility located in Little Rock, Arkansas (Little Rock), that will sit on approximately 300 acres of land. Construction began on the new facility in 2022. The development approach for the new campus has been modular and calibrated to demand trends for Trex Outdoor Living Products. During 2025, scrap polyethylene processing began at this facility. Decking production at this facility is expected to begin in 2027.

In addition, we prioritize cost reduction projects and continuous improvement opportunities, primarily related to automation, modernization, energy efficiency, and raw material processing, and remain focused on innovation and new product development. We have also broadened the range of raw materials that we can use to produce a consistent and high-quality finished product. In connection with national building code listings, we maintain a quality control testing program.

Suppliers

We conduct supply chain assessments when considered necessary in relation to the significance of the purchase and business opportunity for the Company. Assessments include in-person reviews and tours of operating facilities. The Company is committed to conducting business activities with the highest standards of business ethics and in accordance with all applicable laws and regulations. As stated above, our Vendor and Customer Code of Conduct and Ethics, our Company Code of Conduct and Ethics, and our Human Rights Policy apply to all suppliers of the Company.

Table of Contents

The production of most of our decking products requires a supply of reclaimed wood fiber and scrap polyethylene. We fulfill requirements for raw materials under both purchase orders and supply contracts. In the year ended December 31, 2025, we purchased our reclaimed wood fiber requirements under purchase orders and long-term supply commitments. All of our polyethylene purchases are under short-term supply contracts that generally have a term of approximately one year for which pricing is negotiated as needed, or under purchase orders that do not involve long-term supply commitments.

•

Reclaimed Wood Fiber: Most of our reclaimed wood supply originates in North America through relationships with cabinet makers, wood flooring manufacturers, sawmills, lumberyards and other entities that generate and collect wood byproducts in their operations. In addition, we purchase scrap select wood chips generated from various farming operations. If the reclaimed wood fiber meets our specifications, our reclaimed wood fiber supply agreements generally require us to purchase at least a specified minimum and at most a specified maximum amount of reclaimed wood fiber. Depending on our needs, the amount of reclaimed wood fiber that we actually purchase within the specified range under any supply agreement may vary significantly from year to year.

•

Scrap Polyethylene: The polyethylene we consume is primarily composed of scrap plastic film and plastic bags. We will continue to seek to meet our future needs for scrap polyethylene from the expansion of our existing supply sources and the development of new sources. We believe our use of multiple sources provides us with a cost advantage and facilitates an environmentally responsible approach to our procurement of polyethylene. Our ability to source and use a wide variety of polyethylene from third party distribution and manufacturing operations is important to our cost strategy. We maintain this ability through the continued expansion of our plastic reprocessing operations in combination with the advancement of our proprietary material preparation and extrusion processes.

In addition, we outsource the production of certain products to third-party manufacturers.

Training

Trex University is our state-of-the-art training facility located near our Virginia manufacturing plant designed to educate and train retailers, contractors and other partners on the benefits of Trex aesthetically pleasing, high-performance, low-maintenance, eco-friendly outdoor living products. In addition, Trex Academy is an online multimedia content hub dedicated to helping the Trex Do-It-Yourself customer bring their deck dreams to life by providing how-to content.

Competition

Our primary competition for our composite decking and railing products consists of wood products, which constitute a substantial majority of decking and railing sales, as measured by linear feet of lumber. Many of the conventional lumber suppliers with which we compete have established ties to the building and construction industry and have well-accepted products. A majority of the lumber used in wood decks is pressure-treated lumber. Southern yellow pine and fir have a porosity that readily allows the chemicals used in the pressure treating process to be absorbed. The same porosity makes southern yellow pine susceptible to absorbing moisture, which causes the lumber to warp, crack, splinter and expel fasteners. In addition to pine and fir, other wood materials used for decking include redwood, cedar, and tropical hardwoods such as ipe, teak, and mahogany. While these products are often significantly more expensive than pressure-treated lumber, they do not eliminate key disadvantages associated with wood, including susceptibility to weathering, fading, biological deterioration, insect damage, splinters, and the need for ongoing maintenance such as sanding, staining, and sealing.

In addition to wood, we also compete with other manufacturers of wood-alternative products. Industry studies indicate that we have the leading market share of the wood-alternative segment of the decking and railing market. Our principal competitors include Azek (a division of James Hardie Industries PLC), Deckorators (a division of UFP Industries, Inc.), and Fiberon (a division of Fortune Brands, Inc.).

Our ability to compete depends, in part, on a number of factors outside our control, including the ability of our competitors to develop new wood-alternative decking and railing products that are competitive with our products. We believe that the principal competitive factors in the decking and railing market include product quality, price, aesthetics, maintenance cost, distribution, brand strength, and warranties. We believe we compete favorably with respect to these factors. We believe that our products offer aesthetic and cost advantages over the life of a deck when compared to other types of decking and railing materials. Although a contractor-installed deck built with Trex products using a pressure-treated wood substructure generally costs more than a deck made entirely from pressure-treated wood, Trex products are low maintenance compared to the on-going maintenance required for a pressure-treated deck and are therefore, less costly over the life of the deck. We believe that our manufacturing process and utilization of relatively low-cost raw material sources provide us with a competitive cost advantage relative to other manufacturers of wood-alternative decking and railing products. The scale of our operations also confers cost efficiencies in manufacturing, sales and marketing.

Table of Contents

Seasonality

Our operating results have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions may reduce the level of home improvement and construction activity and can shift demand for our products to a later period. As part of its normal business practice and consistent with industry practice, Trex has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs.

Government Regulation

Our business activities are subject to various federal, state and local laws and regulations. Costs and accruals incurred to comply with these governmental regulations are presently not material to our capital expenditures, results of operations and competitive position. Although there is no assurance that existing or future government laws applicable to our operations or products will not have a material adverse effect on our capital expenditures, results of operations and competitive position, we do not currently anticipate material expenditures for government regulations.

We are also subject to federal, state and local environmental regulation. The emissions of particulates and other substances from our manufacturing facilities must meet federal and state air quality standards implemented through air permits issued to us by the Department of Environmental Quality of the Commonwealth of Virginia, the Division of Environmental Protection of Nevada’s Department of Conservation and Natural Resources, and the Division of Environmental Quality of Arkansas’ Department of Energy and Environment. Our facilities are regulated by federal and state laws governing the disposal of solid waste and by state and local permits and requirements with respect to wastewater and storm water discharge. Compliance with environmental laws and regulations has not had a material adverse effect on our business, operating results or financial condition.

Our operations also are subject to workplace safety regulation by the U.S. Occupational Safety and Health Administration, the Commonwealth of Virginia, and the States of Nevada and Arkansas. Our compliance efforts include safety awareness and training programs for our production and maintenance employees.

Intellectual Property

Our success depends, in part, upon our intellectual property rights relating to our products, production processes and other operations. We rely upon a combination of trade secret, nondisclosure and other contractual arrangements, and patent, copyright and trademark laws, to protect our proprietary rights. We have made substantial investments in manufacturing process improvements that have enabled us to increase manufacturing line production rates, facilitate our development of new products, and produce improvements in our existing products’ dimensional consistency, surface texture and color uniformity.

Intellectual property rights may be challenged by third parties and may not exclude competitors from using the same or similar technologies, brands or works. We seek to secure effective rights for our intellectual property but cannot provide assurance that third parties will not successfully challenge, or avoid infringing, our intellectual property rights.

We consider our trademarks to be of material importance to our business plans. The U.S. Patent and Trademark Office has granted us federal registrations for many of our trademarks. Federal registration of trademarks is effective for as long as we continue to use the trademarks and renew their registrations. We do not generally register any of our copyrights with the U.S. Copyright Office but rely on the protection afforded to such copyrights by the U.S. Copyright Act. This law provides protection to authors of original works, whether published or unpublished, and whether registered or unregistered.

We have two current U.S. Patents for decking technology. We intend to maintain our existing patents in effect until they expire on January 15, 2038 and May 23, 2038, respectively, as well as to seek additional patents as we consider appropriate.

We enter into confidentiality agreements with our employees and limit access to and distribution of our proprietary information. If it is necessary to disclose proprietary information to third parties for business reasons, we require that such third parties sign a confidentiality agreement prior to any disclosure.

Human Capital

Overview As of December 31, 2025, Trex employed 1,839 full-time employees. Our people are what have fueled our growth as the world’s #1 brand of sustainably made, wood-alternative decking and deck railing for nearly three decades. As we look to the future, Trex is poised for growth and innovation and that growth is dependent upon our people’s talent and commitment. We continue

Table of Contents

to invest in our people as we execute on our strategic talent management plan which aims to support our employees in gaining the competencies needed to advance and enjoy long-lasting careers at Trex.

Pay Equity As an equal opportunity employer, Trex believes in compensating our people fairly and without discrimination — regardless of gender, race, or any protected characteristic. Our strong reputation as an industry leader is built on consistently offering competitive hourly wages, salaries, and total compensation packages.

To ensure pay parity for similar roles, we use a structured compensation-grade system that defines objective pay ranges before we evaluate any candidate. For some roles, we supplement this approach with targeted market studies to confirm our compensation remains competitive, aligned with market benchmarks, and internally equitable. We review total rewards regularly to support our efforts to attract and retain top talent.

Each period, we benchmark our pay ranges against industry standards and update our compensation structure to remain market competitive. Annually, we benchmark hourly wages in our local markets, participate in industry salary surveys, and analyze relevant results to keep our hourly pay competitive. We also undertake regular pay-equivalence analyses to detect any unintended gaps. These analyses focus primarily on our salaried staff because our hourly wages are standardized by role.

In 2025, we refined our pay-mix philosophy to provide managers with more flexibility — enabling the creation of total compensation packages tailored to meet employee needs, while remaining fair and equitable. Our commitment to fair pay and humane working conditions is also enshrined in our broader Human Rights Policy — which underscores how we conduct business and treat our people. The policy is publicly available at (www.trex.com/our-company).

Development and Recruiting Developing internal talent is another key multi-year infrastructure investment for Trex. To help support our strategic talent development, we continue to invest in enabling tools, systems, and training to strengthen our decision making and accelerate progress. This includes new training for managers in the areas of team development, performance reviews, and recognition.

In addition, the Trex Leadership Academy, a 12-month program, continues to develop and refine the competencies and leadership skills of high potential team members. Trex’s tuition reimbursement policy assists team members in achieving their full potential by furthering their education, affording them opportunities to grow their skills set and favorably impact the business. Safety remains a core value at Trex and in 2024 hourly manufacturing onboarding was modified to include more time for new team members to learn the process and incorporate additional safety best practices which has resulted in improved safety and retention outcomes.

While significant investments have been made in internal development, recruiting outside talent continues to infuse the Company with new and diverse perspectives. Our summer intern program continues to grow and welcomes students from both universities and vocational schools across the mid-Atlantic. This program along with campus recruitment has created a pipeline of young talent, while we also continue to attract some of the most talented senior leaders from around the country to fill key leadership positions.

Engagement and Culture We continue to invest in employee engagement and related action planning by conducting Gallup surveys. Our people managers use the results to develop specific action plans to drive engagement throughout our organization. We also evolved our approach to curation of culture, providing training through an internal trainer to hourly employees in addition to leaders. This multi-year roll out of culture training targets all Trex team members to create shared understanding and expectations. Additionally, we conducted our first Spanish language cultural training for our Spanish speaking employees.

Trex is committed to building a workforce that is reflective of the communities in which we operate. Embracing diverse perspectives and fostering a culture of inclusion and belonging are at the core of what has fueled Trex’s legacy of innovation. We continue to find new ways to increase opportunities for underrepresented team members, including partnering with local agencies to provide employment opportunities to neuro-diverse candidates.

At Trex, our people fuel our growth and innovation. We are committed to reinvesting in our team and executing our strategic talent management plan at the highest level.

Environmental and Occupational Safety

Environmental

The Company has been committed to sustainability since our inception more than 30 years ago, creating eco-friendly products from reclaimed and recycled materials. Trex’s high-performance, low-maintenance composite decking is made from 95% recycled and reclaimed materials. The Company’s commitment to improving our environmental footprint includes developing and offering more sustainable products to the market as well as advancing sustainability and efficiency in our operations. From continuous improvement in our manufacturing practices that reduce the use of energy to making products using industry leading high levels of reclaimed and recycled materials, the Company is able to improve the use of resources, greenhouse gas emissions, and waste streams. The foundation for our commitment to sustainability includes, but is not limited to:

•

Using recycled, reclaimed and other waste resources whenever possible in our manufacturing process;

•

Preventing pollution by maintaining environmental management as a core value;

•

Reducing waste generated in our manufacturing and business operations;

•

Developing and using environmentally acceptable, safe and efficient production methods; and

•

Identifying and complying with all legal and statutory requirements.

Our Environmental Policy, located on our web site at www.trex.com/our-company, outlines our commitment to conducting business in an ethical and socially responsible manner that respects the environment.

The Nominating / Corporate Governance Committee of the Board of Directors oversees the Company’s sustainability matters that are significant to the Company. Periodically, the Committee reviews the Company’s sustainability strategy, initiatives and policies and receives updates from the Senior Vice President, Chief Legal Officer and Secretary, who oversees the Company’s sustainability initiatives. Also, environmental matters relevant to the Company’s operations are the responsibility of the President and Chief Executive Officer, the Executive Vice President and Chief Operating Officer, and the Senior Vice President and Chief Financial Officer.

Trex’s manufacturing facilities on the east coast, west coast, and in the central United States reduce fuel consumption and CO2 emissions by reducing transit distance. We strive to reduce energy use and associated greenhouse gas emissions in Trex manufacturing operations by designing our facilities to run efficiently. In addition, nearly all our factory scrap is recycled back into the manufacturing line. Any product that does not meet quality specifications is reprocessed, which eliminates the need for landfill for product waste.

The Company’s primary resource usage consists of water, natural gas and electricity. The Company develops budgets and plans that improve shareholder return by ensuring the optimal use of each resource, which promotes resource efficiency and minimal waste of the resource. Water management is of critical importance to us. Our Virginia and Nevada manufacturing facilities have closed-loop recirculation systems that run water through multiple cycles of re-use before being returned to the municipal wastewater stream. We prioritize energy savings as part of our ongoing evaluation and optimization of business operations and manufacturing processes. We regularly assess environmental impacts at each stage of our manufacturing process and seek to continually improve our performance. We ensure that all manufacturing facilities meet emission standards for the locality in which they operate and certify to applicable authorities that our emissions are within the relevant locality’s standards.

Market Recognition of Trex Brand’s Environmental Characteristics

The Company’s internal standards for environmental stewardship and product integrity are recognized year-over-year in the marketplace. Trex was named to the Barron’s “100 Most Sustainable Companies” list for 2025. Trex earned top honors in the Environment + Energy Leader Awards as top product of the year and judge's choice winner. In addition, Trex was also recognized as Sustainable Brand Leader in the decking category of Green Builder’s annual Reader’s Choice Survey for the 15th consecutive year.

Trex environmental benefits are recognized by the receipt of the Leadership in Energy and Environmental Design (LEED) certification by the United States Green Building Council. Trex decking products meet LEED requirements for builders and our commercial products have contributed to the LEED certifications of some high-profile venues. LEED is a point-based system designed to reward points to building projects that incorporate efficient, and safe eco-friendly products, leading to a building’s designation as LEED Silver, Gold or Platinum. Trex decking can add up to four points to a project in the Materials and Resources category for being composed of 95% recycled and reclaimed materials. As a U.S. Green Building Council member, Trex works along with council members to transform the way buildings and communities are designed, built and operated with the goal of creating environmentally and socially responsible spaces that improve the quality of life.

Occupational Health and Safety

The health and safety of our employees is our highest priority. We have a strong Environmental, Health and Safety (EHS) program that focuses on developing and implementing policies and effective safety training programs, as well as performing internal safety assessments to ensure a company-wide culture of safety and accountability.

Every member of the Trex community plays a vital role in maintaining a safe work environment. Our Chief Executive Officer and Board of Directors are responsible for ensuring compliance with applicable laws and the Company’s own standards and practices. At Trex, our Occupational Health and Safety Policy lays out the key principles that guide our approach and sets clear expectations for every department across the company. The Trex Occupational Health and Safety Policy, located on our website at www.trex.com/our-company, sets forth our commitment to sustaining a compliant and safety-conscious work environment, keeping safety at the forefront of our business, and is based on:

•

Compliance with statutory, regulatory and other legal requirements;

•

A comprehensive understanding of worker expectations;

•

Demonstrating employee safety leadership in all processes while striving to consistently improve performance; and

•

Tracking company and site level safety performance metrics including common lagging indicators, such as injury rates, but also leading indicators such as safety observations, near-misses, and proactive actions taken at the sites to ensure worker safety.

Each of our manufacturing sites have dedicated health and safety professionals (EHS professionals) and safety committees. All EHS professionals are required to complete continuing education courses to build internal expertise and capacity.

Our Safety Steering Committee continues to grow and add organizational alignment. The Safety Steering Committee’s charter creates a forum for managers and leaders from all functional areas to discuss health and safety. This includes reviewing incidents and corrective actions from across the organization, sharing information related to safety improvements, and providing transparency related to health and safety performance monthly.

Our Rules to Live By campaign has become the foundation of our safety focus and outlines expectations of employee compliance with safety rules related to high-risk activities such as powered industrial trucks, lockout/tagout, and control of hazardous energy, confined spaces, machine guarding, working at height, and hoisting and rigging.

In 2025, Trex improved and re-launched numerous health and safety initiatives including FASTT. FASTT is a common safety-observation and risk assessment acronym that stands for: F - Find the task, A- Analyze the hazards, S - Select controls, T- Take action, and T -Tell others/track results. Our FASTT response program is a weekly meeting of frontline leaders and support personnel focused on identifying and correcting safety non-compliance on the production floor to prevent incidents from occurring. We have also revitalized our safety observation card program to increase engagement with employees on the floor and give them a tool to create ownership of their personal health and safety as well as the health and safety of the people they work with.

Item 1A. Risk Factors

Our business operates in one reportable segment, Trex, and is subject to a number of risks, including the following.

Risks Related to the Distribution and Sale of Our Product



Risk	Discussion
Description We may not be able to grow unless we increase market acceptance of our products, compete effectively and develop new products and applications. Impact Our failure to compete successfully could have a material adverse effect on our ability to replace wood products or increase our market share amongst wood-alternative products. • If our products do not meet emerging demands and preferences, we could lose market share, which could have a material adverse effect on our business. • In addition, substantially all of our revenues are derived from sales of our proprietary wood/polyethylene composite material. Although we have developed, and continue to develop, new products made from other materials, if we should experience significant problems, real or perceived, with acceptance of the Trex wood/polyethylene composite material, our lack of product diversification could have a significant adverse impact on our net sales levels.	Our primary competition consists of wood products, which constitute a substantial majority of decking, railing, fencing, and deck framing sales. Since composite products were introduced to the market in the late 1980s, their market acceptance has increased. Our ability to grow depends, in part, on our success in continuing to convert demand for wood products into demand for our composite products. Many of the conventional lumber suppliers with which we compete have established ties to the building and construction industry and have well-accepted products. Our ability to compete depends, in part, upon a number of factors outside our control, including the ability of competitors to develop new alternatives that are more competitive with Trex products. Our ability to identify and respond to emerging consumer demands and preferences for our products depends, in part, on how successfully we develop, manufacture and market new products. To increase our market share, we must overcome: • Lack of awareness of the enhanced value of composite products in general and our products in particular;
	• Resistance of many consumers and contractors to change from well-established wood products; • Consumer lack of awareness that the greater initial expense of our products compared to wood is a one-time cost that is reduced over time as our products have lower maintenance costs and a longer life span than wood; • Established relationships existing between suppliers of wood products and contractors and homebuilders; • Actual and perceived quality issues with first generation composite products; and • Competition from other wood-alternative manufacturers.

Table of Contents



Risk	Discussion
Description The demand for our products is influenced by the home improvement market and could be adversely affected by conditions that negatively impact this market. Impact We cannot predict conditions that may negatively impact the home remodeling and new home construction environment. Any economic downturn or adverse changes in the home improvement market could reduce consumer income or equity capital available for spending on discretionary items, which could adversely affect the demand for our products.	The demand for our composite decking and railing products is influenced by the general health of the economy, the level of home improvement activity and, to a much lesser extent, new home construction. These factors are affected by home equity values, credit availability and interest rates, consumer confidence, income and spending habits, employment, inflation, and general economic conditions.



Risk	Discussion
Description We may not be able to fully maintain or expand our wholesaler and dealer channels. Impact If we fail to compete successfully for wholesale distributors and dealers, our business could experience material adverse effects, which could negatively impact profitability and cash flows.	We sell most of our composite decking and railing products through our network of wholesale distributors who, in turn, sell to retail lumber outlets. Our growth strategy depends on maintaining and expanding this network and on our ability to compete with other entities for these channels. In order to successfully compete for wholesaler distributors, dealers and retail lumber outlets, we must accurately assess their customers’ needs and preferences.



Risk	Discussion
Description Certain of our customers account for a significant portion of our sales, and the loss of one or more of these customers could have an adverse effect on our business. Impact The loss of a significant customer could have a significant negative impact on our business, results of operations and financial condition.	A limited number of our customers account for a significant percentage of our sales. For the years ended December 31, 2025, 2024, and 2023, three customers of Trex represented approximately 73%, 81%, and 72%, respectively, of the Company’s total net sales. We expect that a significant portion of our sales will continue to be sold through a small number of customers, and certain customers will continue to account for a significant portion of our sales.

Risk	Discussion
Description Our operating results may vary quarter to quarter due to the level of inventory maintained in our distribution channel. Impact We have limited visibility to project inventory levels in our two-step distribution channel. Any sudden fluctuation in demand from our distribution partners may require us to quickly increase or decrease our manufacturing inputs and outputs. If we are unable to effectively respond in a timely manner our short-term results of operations may be negatively impacted.	We sell our composite decking and railing products through our distribution channel who, in turn, sell to end-use consumers. Our distribution partners manage their inventory levels by forecasting demand for our products, placing orders for the products, and maintaining product inventories in order to meet consumer demand. Inventory levels respond to a number of factors, including, without limitation, changes in product price, the number of competitors, product innovation, and the level of discretionary spending by consumers. Therefore, our operating results are subject to inventory stocking decisions made by our distribution partners and may vary quarter to quarter. Past performance will not necessarily indicate future performance.



Risk	Discussion
Description The demand for our outdoor living products may be negatively affected by erratic, or prolonged adverse weather conditions, and our operating results may vary quarter to quarter due to seasonality. Impact Seasonal, erratic, or prolonged adverse weather conditions may reduce the level of home improvement and construction activity and can shift sales of our products to a later period or decrease overall sales in affected locations, which could have a negative impact on our results of operations and liquidity.	Our products are generally purchased shortly before installation and used in outdoor environments. As a result, there is a correlation between the amount of product we sell and weather conditions during the time they are to be installed. Erratic or prolonged adverse weather conditions may interfere with home improvement or ordinary construction, delay projects, or lead to cessation of construction involving our products. In addition, our operating results have historically varied from quarter to quarter due to seasonality. As part of normal business practice and consistent with industry practice, we have historically offered incentive programs to our distributors and dealers to build inventory before the start of the prime deck-building season in order to ensure adequate availability of our products to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs.

Discussion

       
Description
 
We depend on third parties for transportation services and the lack of availability of transportation and/or increases in cost could materially adversely affect our business and operations.
 
Impact
 
If the required supply of third-party transportation services is unavailable when needed, we may be unable to deliver our products in a timely manner and, therefore, unable to sell our products at full value, or at all. Similarly, if any of these providers were unavailable to deliver raw materials to us in a timely manner, we may be unable to manufacture our products in response to customer demand. This could harm our reputation, negatively impact our customer relationships and have a material adverse effect on our financial condition and results of operations. In addition, a material increase in transportation rates or fuel surcharges could have a material adverse effect on our profitability.
 
Our business depends on the transportation by third parties of both raw materials to us and finished goods to our customers. In particular, a significant portion of our finished goods are transported by flatbed trucks, which are occasionally in high demand (especially at the end of calendar quarters) and/or subject to price fluctuations based on market conditions and the price of fuel.

Risks Related to the Manufacture of Our Product



Risk	Discussion
Description Our business is dependent on consistently producing a product which is available when needed to meet the demands of our customers. As our business grows, we must adjust capacity to meet customer needs and provide increased throughput on our existing capacity. Impact Our sales growth and profitability could suffer from our failure to effectively pair supply and demand for our products. Our customers’ demands for varying quantities of products and delivery items throughout the year, and increased demand year to year, require monitoring and the ability to adjust production in accordance with these demands. Failure to do so can lead to lost or reduced sales and have a negative effect on earnings.	In order to meet customer demand in a timely manner, we must adjust capacity to meet customer needs and provide increased throughput on our existing capacity. Our sourcing team must obtain raw materials on a timely basis at an appropriate volume.



Risk	Discussion
Description We have made and may continue to make significant capital investments in new and existing manufacturing facilities, that may become impaired or obsolete and result in a charge to our earnings. In addition, underutilization of any such investments may result in reduced profitability through reduced gross profit and lower gross margins. Impact Our ability to achieve the expected benefits and returns from our capital investments, such as increased production, improved efficiency, cost savings, or diversification into new product markets, is subject to estimates, assumptions, and market risks. If the actual results differ from our estimates and assumptions, we may not achieve the benefits from the investments within the estimated time frame, if at all, which could adversely affect our financial condition and results of operations.	We have made and may continue to make significant investments in new manufacturing facilities, upgrading our existing facilities and acquiring businesses or operations. These investments sometimes involve the implementation of new technologies and replacement of existing equipment. While we anticipate that these investments will increase production, improve efficiency, achieve cost savings, or allow us to diversify into new product markets, we cannot be certain we will realize the benefits of these initiatives when anticipated or at all. Failure to achieve the expected benefits from our investments may result in reduced cash flows in future periods, obsolete or impaired assets, and charges to our earnings.

Risk	Discussion
Description Our prospects for sales growth and profitability may be adversely affected if we fail to maintain product quality and product performance at an acceptable cost. Impact If we are unable to produce high-quality products at standard manufacturing rates and yields, unit costs may be higher. A lack of product performance could impede acceptance of our products in the marketplace and negatively affect our profitability. Future material increases to our warranty reserve could have a significant adverse effect on our profitability and cash flows. In the event lawsuits relating to alleged product quality issues are brought against us in the future, such lawsuits may be costly and could cause adverse publicity, which in turn could result in a loss of consumer confidence in our products and reduce our sales. Product quality claims could increase our expenses, have a material adverse effect on demand for our products and decrease net sales, net income and liquidity.	In order to expand our net sales and sustain profitable operations we must maintain the quality and performance of our products. We continue to receive and settle claims and maintain a warranty reserve related to decking, railing, and accessory products sold, including decking products produced at our Nevada facility prior to 2007 that exhibits surface flaking. We have limited our financial exposure for surface flaking by settling a nationwide class action lawsuit that provides that a consumer’s remedy is limited to the replacement of product and a partial labor reimbursement. The establishment of reserves is an inherently uncertain process involving estimates of the number of future claims and the average cost of claims, our ultimate losses may differ from our warranty reserve. Increases to the warranty reserve and payments for related claims could have a material adverse effect on our future profitability and cash flows.



Risk	Discussion
Description Our business is subject to risks in obtaining the raw materials we use. In addition, to the extent we source raw materials internationally, changes in trade policies, including the imposition of tariffs, have and could continue to negatively impact our business, financial condition, and results of operations. Impact Our business could suffer from the termination of significant sources of raw materials, the payment of higher prices for raw materials, the quality of available raw materials, or from the failure to obtain sufficient additional raw materials to meet planned increases in production.	The manufacture of our composite decking and railing products requires substantial amounts of wood fiber and scrap polyethylene. Our business strategy is to create a substantial cost advantage over our competitors by using scrap polyethylene. Our ability to obtain adequate supplies of wood fiber and scrap polyethylene depends on our success in developing new sources that meet our quality requirements, maintaining favorable relationships with suppliers and managing the collection of supplies from geographically dispersed locations. In addition to wood fiber and scrap polyethylene, we also use a small percentage of other materials in making our products, which are sometimes subject to volatility in supply and could negatively affect our profitability. We procure certain of the raw materials we use in the manufacturing of our products from suppliers located outside of the United States. The imposition of tariffs and other potential changes in U.S. trade policy have increased the cost and/or limited the availability of raw materials, which has adversely impacted our business, financial condition and results of operations and could hurt our competitive position.

Risk	Discussion
Description Periods of significant or prolonged inflation could affect our ability to obtain manufacturing inputs at acceptable prices and may negatively impact our profitability. Impact In a competitive environment, we may be unable to increase prices of our products to offset higher costs resulting from significant or prolonged inflationary pressures, which could have a material adverse effect on our business, financial condition, and operating results. In addition, periods of sustained or rapidly increasing inflation may result in decreased spending in the residential and commercial markets and reduce demand for our products, which could further adversely impact our business.	Our business may be directly affected by significant or prolonged inflationary pressures on raw materials and transportation. We will look to offset increased input costs through cost reduction projects, purchasing strategies, and increased production efficiencies and improvement opportunities to enhance our margins. Specifically, our efforts would primarily center on increased automation, modernization, enhanced energy efficiency and improvements to raw material processing. To the extent that these actions would not offset the impact of inflation we would seek to increase the price of our products to our customers. At the same time, we would expand our marketing campaigns, including campaigns to highlight the advantages of our decking over wood, as well as campaigns focused on innovation and new product development that further strengthens our consumer brand and distribution advantages.
	In general, we believe that an effect of inflation would be a short-term disruption and that, over time, we would offset increased input costs through cost reduction projects, purchasing strategies, and increased production efficiencies and improvement opportunities to enhance our margins. In addition, we would be able to increase prices to counteract the majority of any inflationary effects of increasing costs and to generate sufficient cash flows to maintain our productive capability.



Risk	Discussion
Description Labor shortages or increases in labor costs could adversely impact our business and results of operations. Impact We rely heavily on our employees and any shortage of qualified labor could adversely affect our business. If we are not successful in our recruiting and retention efforts, we could encounter a shortage of qualified employees in future periods. Any such shortage would decrease our ability to produce sufficient quantities of our product to serve our customers effectively. Such a shortage may also require us to pay higher wages for employees and incur a corresponding reduction in our profitability.	Labor is one of the primary components of our production process. Our success is dependent upon recruiting qualified employees to manufacture our product. Our future success depends on, among other things, our ability to identify, attract, hire, train, retain and motivate operational personnel on a timely basis as we continue our pace of growth. If we fail to do so, our ability to maintain and grow our business could be adversely impacted. Further, improvements in the economy and labor markets could impact our ability to attract and retain key personnel.

Risks Related to the Availability of Capital



Risk	Discussion
Description Our ability to continue to obtain financing on favorable terms, and the level of any outstanding indebtedness, could adversely affect our financial condition and ability to compete. Impact Our ability to make future principal and interest payments, borrow and repay amounts under our senior credit facility and continue to comply with our loan covenants will depend primarily on our ability to generate sufficient cash flow from operations. Our failure to comply with our loan covenants might cause our lenders to accelerate our repayment obligations under our senior credit facility, which may be declared payable immediately based on a default.	Our ability to continue to obtain financing on favorable terms may limit our discretion on some business matters, which could make it more difficult for us to expand, finance our operations and engage in other business activities that may be in our interest. In addition, our senior credit facility may impose operating and financial restrictions. At certain periods during the year, we may borrow significant amounts on our senior credit facility for working capital purposes. In addition, we may borrow on the senior credit facility to pursue strategic opportunities or other general business matters. Accordingly, our future level of indebtedness and the terms of our borrowings could have important consequences.

Risks Related to Other Matters



Risk	Discussion
Description Our business, results of operations and financial condition may be disrupted and adversely affected by global public health pandemics or geopolitical conflicts. Impact If our employees or the employees of our suppliers or transportation providers are unable to work because of illness related to a global public health pandemic, or if we or our suppliers or transportation providers are forced to temporarily cease operations, either on a voluntary or mandatory basis, then we may have a period of reduced operations and be unable to supply our customers in a timely manner, which could have a material negative impact on our business. If geopolitical conflicts disrupt the operations of our distributors and retail outlets or negatively impacts economies in the United States, Canada and the rest of the world, our business, results of operations and financial condition may be adversely affected.	Our business, results of operations and financial condition may be adversely affected if a global public health pandemic interferes with the ability of our employees, suppliers and other business partners to perform their respective responsibilities and obligations relative to the conduct of our business. We monitor the outbreak of any global public health pandemic or global political conflicts and evaluate the impact on our business as information emerges. The extent to which the impact of a global public health pandemic or a continuing global political conflict may have on our business, supply chains, commodity and fuel prices, and prices of raw materials will depend on future developments, which may be highly uncertain and cannot be predicted.

Risk	Discussion
Description Climate change and legal or regulatory responses thereto may have a long-term adverse impact on our business and results of operations. Impact There is concern that a gradual increase in global average temperatures due to increased concentration of carbon dioxide and other greenhouse gases in the atmosphere could cause significant changes in weather patterns and an increase in the frequency, duration, and severity of natural disasters. In addition, the concern over climate change may result in additional laws or regulations designed to reduce or mitigate the effects of carbon dioxide and other greenhouse gas emissions on the environment. Compliance with newly enacted laws and regulations could impose operational and compliance burdens which may negatively impact our financial condition and results of operations.	We continue to strive to minimize the environmental impact of Trex operations, remain one of the largest recyclers of polyethylene in the U.S. and continue to benefit from increasing consumer interest in our environmentally friendly composite product offerings that leverage recycled and reclaimed materials. Any significant changes in weather patterns or increases in the frequency, duration and severity of natural disasters are beyond our control and could disrupt our supply chain, increase our product costs, impact demand for our product, or impair our ability to deliver product to our customers. In addition, we cannot predict what environmental legislation or regulations will be enacted in the future related to climate issues, or how existing or future laws or regulations will be administered or interpreted. Compliance with more stringent laws or regulations, or stricter interpretation of existing laws, may require additional expenditures. Any increased energy or compliance costs and expenses may cause disruptions in, or an increase in the costs associated with, the manufacturing and distribution of our products.

Description
 
Cyberattacks and other security breaches could compromise our proprietary and confidential information which could harm our business and reputation.
 
Impact
 
While we have certain safeguards in place to reduce the risk of and detect cyber-attacks, our information technology networks and infrastructure may be vulnerable to unpermitted access by hackers or other breaches, or employee error or malfeasance. Any such compromise of our data security and access to, or public disclosure or loss of, confidential business or proprietary information could disrupt our operations, damage our reputation, provide our competitors with valuable information and subject us to additional costs, which could adversely affect our business.

In the ordinary course of our business, we generate, collect and store confidential and proprietary information, including intellectual property, business information and employee data. The secure storage, maintenance, and transmission of and access to this information is important to our operations and reputation. Computer hackers may attempt to penetrate our computer systems and, if successful, misappropriate our proprietary and confidential information including e-mails and other electronic communications.
 
In addition, an employee, contractor, competitor, or other third party with whom we do business may attempt to obtain such information and may purposefully or inadvertently cause a breach involving such information.
 
We also collect limited information on consumers. Although we do not collect any highly sensitive information, there is a risk that a cybersecurity attack could compromise consumer’s names, addresses and other personal information.
 
Proactive measures that reduce our risk of a cybersecurity incident include:
 
•Maintaining cybersecurity insurance to protect against risks related to cyber-attacks and other security breaches.
•Partnering with an enterprise grade security solutions integrator (SSI) that leverages deep industry expertise to help us build and run holistic cybersecurity programs designed to reduce our overall risk profile. The SSI performs regular audits to evaluate our current security posture and prioritize our improvement plans.
•Implementing an information security training and compliance program for employees. We test our employees monthly with simulated “phishing” attacks. Additionally, we run annual security awareness video training programs and occasional ad hoc awareness sessions as needed.
 
Despite these proactive measures, there is no guarantee that these measures will prevent a cybersecurity incident that could have a material adverse effect on the Company.

Technical and regulatory limitations may impact our ability to effectively and timely adopt Artificial Intelligence (AI) and machine learning solutions.
 
Impact

We have made and may continue to make advancements in adopting AI and machine learning throughout our business.  We anticipate that the continued implementation of this technology will improve efficiency and create cost savings across the organization.

Table of Contents

       
While we are currently using AI and machine learning in various areas of our business, technical and regulatory limitations may impact our ability to utilize AI and machine learning across other areas of our business. Failure to adopt AI and machine learning in other areas could cause advancements in our business and production process to fall behind our competitors, impacting our ability to compete effectively.
 
      Our ability to continue to adopt AI and machine learning depends, in part, on the resources available to develop, deploy, and monitor these systems. Accordingly, our organization has adopted guiding principles, as well as a governance policy for AI and machine learning. Our guiding principles focus on the risks and consideration associated with AI and machine learning and help support the Company's responsible use of these technologies. Our AI governance policy provides a structured approach to identifying, assessing, and prioritizing use cases anticipated to yield optimal business value while simultaneously minimizing business risks.
 
Our Information Technology department, in partnership with our Legal department, and other business leaders, are responsible for monitoring the use of AI and machine learning within the organization, along with the regulatory environment in which AI and machine learning operate. 
 
While the Company has adopted the use of AI and machine learning in various areas of the organization and intends to adopt AI and machine learning in other areas, adoption does not guarantee efficiencies, optimizations, or innovations are made throughout the organization.

Item 2. Properties

We own and lease certain properties, as noted in the below table:


Description	Square Footage/ Acres	Leased / Owned	Lease Expiration Dates	Location

Corporate Headquarters Office	62,210 SF	Owned	N/A	Virginia

Corporate Headquarters Land	8 Acres	Owned	N/A	Virginia

Trex Warehouse, Research and Development, Storage, Training and Manufacturing Facilities	2,270,205 SF	Leased	2026 – 2037	Virginia / West Virginia / Nevada/ Arkansas

Trex Manufacturing Facilities, Storage and Office Space	1,530,236 SF / 475 Acres	Owned	N/A	Virginia / Nevada / Arkansas

We regularly evaluate our various facilities and equipment and make capital investments where necessary. In 2025, we spent a total of $233.6 million on capital expenditures and intangibles, including $167.8 million related to construction of our Arkansas facility, $21.2 million in safety, environmental, and general support, $10.0 million investment in our Enterprise Resource Planning (ERP) tool and other platforms, and $22.0 million in all other including cost reduction initiatives and capacity expansion at our existing facilities.

In October 2021, the Company announced plans to add a third manufacturing facility located in Little Rock, Arkansas (Little Rock). Construction on the new facility began in the second quarter of 2022. In connection with the construction of the new facility, during 2024 the Company and Little Rock entered into an agreement in which Little Rock agreed to issue up to $450 million of its industrial revenue bonds (IRBs) for the purpose of constructing a manufacturing facility. Under the agreement, the Company transferred ownership of the facility to Little Rock and simultaneously leased the related asset from Little Rock. The Company is also the purchaser of the IRBs and, therefore, is the bondholder as well as the lessee of the Little Rock facility purchased with the IRB proceeds.

As a result of the agreement, the Company was able to reduce the cost of certain state and local tax expenditures for twenty years. The Company has a purchase option included in the lease agreement for below the fair value of the asset, which prevents the transfer of the asset to Little Rock from being recognized as a sale. Furthermore, the Company has not derecognized the transferred asset and continues to recognize it in property, plant and equipment in the Consolidated Balance Sheets. The Company has the right and intends to set-off any obligations to make payments under the finance liability, with proceeds due from the IRBs. The liability and IRB asset are equal and are reported net in the Consolidated Balance Sheets.

For information about our leases, see Note 10 to our Consolidated Financial Statements appearing elsewhere in this report. The equipment and machinery we use in our operations consist principally of plastic and wood conveying and processing equipment. We own all of our manufacturing equipment. We lease some equipment, primarily forklifts, at our facilities under operating leases.

Item 3. Legal Proceedings

The Company has lawsuits, as well as other claims, pending against it which are ordinary routine litigation and claims incidental to the business. Management has evaluated the merits of these lawsuits and claims and believes that their ultimate resolution will not have a material effect on the Company’s consolidated financial condition, results of operations, liquidity or competitive position.

Item 4. Mine Safety Disclosures.

Not applicable.

CRITICAL ACCOUNTING ESTIMATES

Our significant accounting policies are described in Note 3 to our Consolidated Financial Statements appearing elsewhere in this report. Our critical accounting estimates include the areas where we have made what we consider to be particularly difficult, subjective or complex judgments in making estimates, and where these estimates can significantly affect our financial results under different assumptions and conditions. We prepare our financial statements in conformity with accounting principles generally accepted in the United States. As a result, we are required to make estimates, judgments, and assumptions that we believe are reasonable based upon the information available. These estimates, judgments and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the periods presented. Actual results could be different from these estimates.

Product Warranty. We warrant that for the applicable warranty period our products, when properly installed, used and maintained, will be free from material defects in workmanship and materials and our decking, cladding, fascia and railing products will not split, splinter, rot or suffer structural damage from termites or fungal decay.

Table of Contents

Products sold on or after January 1, 2023: The warranty period for residential use is 50 years for Transcend® decking, 35 years for Select® decking and Universal Fascia, and 25 years for Enhance® decking and Transcend, Select, Enhance and Signature® railing. The warranty period for commercial use is 10 years, excluding Signature railing and Transcend cladding, which each have a warranty period of 25 years. We further warrant that Trex Transcend, Trex Enhance and Trex Select decking and cladding and Universal Fascia products will not fade in color from light and weathering exposure more than a certain amount and will be resistant to permanent staining from food and beverage substances or mold and mildew, provided the stain is cleaned within seven days of appearance, for the warranty period referred to above. If there is a breach of such warranties, we have an obligation either to replace the defective product or refund the purchase price.

Products sold prior to January 1, 2023: The warranty period is 25 years for residential use and 10 years for commercial use. With respect to Trex Signature railing, the warranty period is 25 years for both residential and commercial use. We further warrant that Trex Transcend, Trex Enhance, Trex Select and Universal Fascia products will not fade in color more than a certain amount and will be resistant to permanent staining from food substances or mold, provided the stain is cleaned within seven days of appearance, for the warranty period referred to above. If there is a breach of such warranties, we have an obligation either to replace the defective product or refund the purchase price.

We maintain a warranty reserve for the settlement of our product warranty claims. We accrue for the estimated cost of product warranty claims at the time revenue is recognized based on such factors as historical claims experience and future claims projections. To estimate our future product warranty reserves, the Company utilizes actuarial techniques to determine a reasonable possible range of amounts to be paid related to defects covered by our product warranty. The actuarial techniques consider claims received, claims closed, and the corresponding amounts paid. Estimates for these elements are quantified using a range of assumptions derived from claim history and consideration of additional factors influencing claim counts or costs incurred to settle claims in order determine the best estimate of future claims for which to record a related liability. We review and adjust these estimates, if necessary, based on the differences between actual experience and historical estimates.

The Company uses the best and most complete underlying information available and a rational methodology to determine its warranty obligations. The Company considers all available evidence to assess the reasonableness of all key assumptions underlying its estimated warranty obligations. During the fourth quarter of 2025, the Company utilized an actuary for the first time to review data on its product warranty. This resulted in a change to the methodology in which the Company estimated its product warranty liability. The reserve increased during the period, largely due to the refined methodology, which decreased the Company’s income before income taxes by $6.0 million, decreased net income by $4.4 million, and reduced diluted earnings per share by $0.04.

For additional information about product warranties, see Notes 3 and 19 to the Consolidated Financial Statements appearing elsewhere in this report.

Revenue Recognition. Trex principally generates revenue from the manufacture and sale of its high-performance, low-maintenance, eco-friendly outdoor living products, consisting of composite decking and railing products, hidden fasteners, and a broad offering of outdoor living accessories. Substantially all of its revenues are from contracts with customers, which are individual customer purchase orders of short-term duration of less than one year. Trex satisfies its performance obligations at a point in time. The shipment of each product is a separate performance obligation as the customer is able to derive benefit from each product shipped and no performance obligation remains after shipment. Upon shipment of the product, the customer obtains control over the distinct product and Trex satisfies its performance obligation. Any performance obligation that remains unsatisfied at the end of a reporting period is part of a contract that has an original expected duration of one year or less. Any variable consideration related to the unsatisfied performance obligation is allocated wholly to the unsatisfied performance obligation and recognized when the product ships and the performance obligation is satisfied and is included in “Accrued expenses and other liabilities, Sales and marketing” in Note 8 to the Consolidated Financial Statements presented in this Form 10-K.

Trex may offer various sales incentive programs throughout the year. It estimates the amount of sales incentive to allocate to each performance obligation, or product shipped, based on direct sales to the customer. The estimate is updated each reporting period and any changes are allocated to the performance obligations on the same basis as at inception. Changes in estimate allocated to a previously satisfied performance obligation are recognized as a reduction of revenue in the period in which the change occurs under the cumulative catch-up method. Should estimates change or prove to have been incorrect, it could negatively affect our results of operations and financial condition. In addition to sales incentive programs, Trex may offer payment discounts. It estimates the payment discount that it believes will be taken by the customer based on prior history using the most-likely-amount method of estimation.

RESULTS OF OPERATIONS

General. Our results of operations are affected by a number of factors, including, but not limited to, the cost to manufacture and distribute products, cost of raw materials, inflation, interest rates, tariffs, consumer spending and preferences, the impact of any supply chain disruptions, economic conditions, and any adverse effects from global health pandemics and geopolitical conflicts.

Net Sales. Net sales consist of sales, net of discounts. The level of net sales is principally affected by sales volume and the prices paid for Trex products. The operating results for Trex have historically varied from quarter to quarter, often due to seasonal trends in the demand for outdoor living products. Seasonal, erratic, or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practices, Trex has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season to ensure adequate availability of its product to meet anticipated seasonal consumer demand and to enable production planning. These incentives include prompt payment discounts and favorable payment terms. In addition, we offer price discounts or volume rebates on specified products and other incentives based on increases in purchases as part of specific promotional programs. The timing of sales incentive programs can impact sales, receivables and inventory levels during the offering period.

Gross Profit. Gross profit represents the difference between net sales and cost of sales. Cost of sales consists of raw materials costs, direct labor costs, manufacturing costs, warranty costs, and freight. Raw materials costs generally include the costs to purchase and transport reclaimed wood fiber, scrap polyethylene and pigmentation for coloring Trex products. Direct labor costs include wages and benefits of personnel engaged in the manufacturing process. Manufacturing costs consist of costs of depreciation, utilities, maintenance supplies and repairs, indirect labor, including wages and benefits, and warehouse and equipment rental activities.

Tariffs account for less than 5% of our cost of sales. The majority of the tariffs are related to purchases of aluminum and steel used in our railing and fastening products. We have and will further mitigate some of the impact on our cost of sales through supplier negotiations and pricing actions.

Selling, General and Administrative Expenses. The largest component of selling, general and administrative expenses is personnel related costs, which include salaries, commissions, incentive compensation, and benefits of personnel engaged in sales and marketing, accounting, information technology, corporate operations, research and development, and other business functions. Another component of selling, general and administrative expenses is branding and other sales and marketing costs, which are used to build brand awareness of Trex. These costs consist primarily of advertising, merchandising, and other promotional costs. Other general and administrative expenses include professional fees, office occupancy costs attributable to the business functions previously referenced, and consumer relations expenses. As a percentage of net sales, selling, general and administrative expenses have varied from quarter to quarter due, in part, to the seasonality of our business.

Below we have included a discussion of our operating results and material changes in our operating results for the year ended December 31, 2025, compared to the year ended December 31, 2024.

Year Ended December 31, 2025 Compared To Year Ended December 31, 2024

	(dollars in thousands)
Total net sales	$	1,174,267	$	1,151,449	$	22,818		2.0	%

Total net sales in 2025 increased $22.8 million, or 2.0%, compared to total net sales in 2024. The increase was substantially all driven by price, as the result of a mid-single digit price increase on many of our decking products in 2025. Additionally, 2024 had the benefit of customers purchasing ahead of the price increase announced for January 1, 2025.

Gross profit	$	459,964		$	501,898		$	(41,934	)		(8.4	)%
Gross margin		39.2	%		43.6	%

Gross profit as a percentage of net sales, gross margin, was 39.2% in 2025 compared to 43.6% in 2024. The decrease was primarily the result of higher raw material costs on aluminum and steel, tariffs, changes to production process driven by refinements made to our Enhance® decking product line, and inefficiencies associated with start-up costs at our Arkansas facility, partially offset by higher pricing.

Selling, General and Administrative Expenses


	Year Ended December 31,

Selling, general and administrative expenses	$	202,003		$	179,995		$	22,008		12.2	%
% of total net sales		17.2	%		15.6	%

Selling, general and administrative expenses increased $22.0 million to $202.0 million, or 17.2% of net sales in 2025. The increase primarily related to increases of $9.6 million in personnel expenses primarily for increased self-insured medical costs and incentive programs, $7.5 million in branding, $3.5 million in digital transformation, and $2.5 million in Arkansas start-up costs, partially offset by lower miscellaneous expenses year over year.

Provision for Income Taxes


	Year Ended December 31,

Provision for income taxes	$	67,546		$	83,468		$	(15,922	)		(19.1	)%
Effective tax rate		26.2	%		25.9	%

The effective tax rate for 2025 was 26.2% compared to 25.9% for 2024. The increase in the effective rate was primarily due to excess tax expense from stock-based awards in 2025 and excess tax benefit from stock-based awards in 2024, as well as reduction in the allowable deduction for foreign derived intangible income.

Total EBITDA decreased 14.8% to $320.9 million for 2025 compared to $376.6 million for 2024. The decrease was driven by lower gross profit and higher selling, general, and administrative expenses.

Year Ended December 31, 2024 Compared To Year Ended December 31, 2023

The Company hereby incorporates by reference the financial results from fiscal year 2023 and the comparison of financial results from fiscal year 2024 to fiscal year 2023 as set forth in the Company’s Management’s Discussion and Analysis of Financial Condition and Results of Operation in the Annual Report on Form 10-K for the year ended December 31, 2024 and filed with the U.S. Securities and Exchange Commission on February 24, 2025.

LIQUIDITY AND CAPITAL RESOURCES

We finance operations and growth primarily with cash flow from operations, borrowings, operating leases, and normal trade credit terms from operating activities.

Sources and Uses of Cash. The following table summarizes our cash flows from operating, investing and financing activities for the years ended December 31, 2025, 2024, and 2023 (in thousands):

EBITDA represents net income before interest, income taxes, depreciation and amortization. EBITDA is not a measurement of financial performance under accounting principles generally accepted in the United States (GAAP). We have included data with respect to EBITDA because management believes the measures facilitate performance comparison between the Company and its competitors. Management considers EBITDA to be important supplemental indicators of our core operating performance because the measures eliminate interest, income taxes, and depreciation and amortization charges to net income. In relation to its competitors, EBITDA eliminates differences among companies in capitalization and tax structures, capital investment cycles and ages of related assets, especially when comparing financial results to prior periods. For these reasons, management believes that EBITDA provides important information regarding the operating performance of the Company. Non-GAAP measures are not meant to be considered superior to or a substitute for our GAAP results.

Operating Activities

Cash provided by operating activities in 2025 was $358.1 million compared to cash provided by operating activities of $143.9 million in 2024. The $214.2 million increase in cash provided by operating activities was primarily a result of a decrease in inventories and decreases in accounts receivable. The decrease in inventories is the result of decreased production in 2025 compared to 2024, while the decrease in accounts receivable was related to the non-recurrence of distributors buying ahead of the January 2025 price increase.

Investing Activities

In 2025, cash used in investing activities for capital expenditures and intangibles was $233.6 million, including $167.8 million related to construction of our Arkansas facility, $21.2 million in safety, environmental, and general support, $10.0 million for our ERP tool and other platforms, and $22.0 million in all other including cost reduction initiatives and capacity expansion at our existing facilities.

Financing Activities

Net cash used in financing activities in 2025 consisted primarily of borrowings under our revolving credit facility used to fund our capital expenditures and to a lesser extent share repurchases.

Stock Repurchase Program. On May 4, 2023, the Trex Board of Directors adopted a new stock repurchase program (2023 Stock Repurchase Program) of up to 10.8 million shares of its outstanding common stock, and terminated the existing stock repurchase program. The 2023 Stock Repurchase Program has no set expiration date and during 2025 the Company repurchased 1,526,927 shares of its common stock under the 2023 Stock Repurchase Program.

Inventory in Distribution Channels. We sell our Trex decking and railing products through a tiered distribution system. We have over 50 distributors worldwide and two national retail merchandisers to which we sell our products. The distributors in turn sell the products to dealers and retail locations who in turn sell the products to end users. Significant increases in inventory levels in the distribution channel without a corresponding change in end-use demand could have an adverse effect on future sales.

Seasonality. The operating results for Trex have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions may reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practice, Trex has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs.

Indebtedness prior to October 10, 2024. On May 18, 2022, the Company entered into a Credit Agreement (Credit Agreement) with certain lending parties thereto (Lenders) to amend and restate the Fourth Amended and Restated Credit Agreement dated as of November 5, 2019. Under the Credit Agreement, the Lenders agreed to provide the Company with one or more Revolving Loans in a collective maximum principal amount of $400,000,000 (Loan Limit) throughout the term, which ends May 18, 2027 (Term). Included within the Loan Limit are sublimits for a Letter of Credit facility in an amount not to exceed $60,000,000; and Swing Line Loans in an aggregate principal amount at any time outstanding not to exceed $20,000,000. The Revolving Loans, the Letter of Credit facility and the Swing Line Loans are for the purpose of raising working capital and supporting general business operations.

On December 22, 2022, the Company entered into a First Amendment to the Credit Agreement (First Amendment). As a part of the First Amendment, the Credit Agreement was amended and restated to provide for an additional Revolving B Loan (as hereinafter defined). Under the First Amendment, the Lenders agreed to provide the Company with a Revolving B Loan consisting of one or more revolving loans in a collective maximum principal amount of $150,000,000 (Revolving B Loan Limit) throughout the term, which

Table of Contents

ended December 22, 2024 (Revolving B Loan Term). Previously, under the Credit Agreement, there was no Revolving B Loan. The First Amendment also provided that TD Bank, N.A. would serve as Syndication Agent.

In conjunction with the First Amendment, on December 22, 2022, the Credit Agreement was amended and restated to refer to the original loan as the Revolving A Loan. The amended and restated Credit Agreement was made an Exhibit A to the First Amendment. All of the terms of the Credit Agreement apply to the Revolving B Loan.

The amended Credit Agreement provides the Company, in the aggregate, the ability to borrow an amount up to the Revolving A Loan Limit during the Revolving A Loan Term (which ends May 18, 2027) and Revolving B Loan Limit during the Revolving B Loan Term. The Company is not obligated to borrow any amount under the revolving loans. Within the respective loan limit, the Company may borrow, repay and reborrow at any time or from time to time while the notes issued pursuant to the Credit Agreement are in effect.

Base Rate Loans (as defined in the Credit Agreement) under the Revolving A Loan and the Swing Line Loans accrue interest at the Base Rate plus the Applicable Rate (as defined in the Credit Agreement) and Term SOFR Loans for the Revolving Loans accrue interest at the rate per annum equal to the sum of Term SOFR for such interest period plus the Applicable Rate (as defined in the Credit Agreement). The Base Rate for any day is a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 0.50%, (b) the rate of interest in effect for such day as publicly announced from time to time by Bank of America (BOA) as its prime rate, and (c) the Term SOFR plus 1.0% subject to certain interest rate floors. Repayment of all then outstanding principal, interest, fees and costs is due at the end of the Term.

With respect to Revolving B Loans (as defined in the First Amendment), for any day, the rate per annum is a tiered pricing based upon the Consolidated Debt to Consolidated EBITDA Ratio. The applicable rate for Revolving B Loans that are Base Rate Loans range between 1.20% and 2.15% and the applicable rate for Revolving B Loans that are Term SOFR/Term SOFR Daily Floating Rate range between 0.20% and 1.15%.

Under the terms of the Security and Pledge Agreement, the Company, subject to certain permitted encumbrances, as collateral security for the above-stated loans and all other present and future indebtedness of the Company owing to the Lenders grants a continuing security interest in certain collateral described and defined in the Security and Pledge Agreement but excluding the Excluded Property (as defined in the Security and Pledge Agreement).

Indebtedness on and after October 10, 2024. On October 10, 2024, Trex entered into a Second Amendment to the Credit Agreement (Second Amendment) with certain lending parties thereto (Lenders) to amend that Credit Agreement dated as of May 18, 2022, as amended by that certain First Amendment dated as of December 22, 2022.

The Second Amendment provides us with Revolving A Loans in the maximum principal amount of $400,000,000 (Revolving A Loans), Revolving B Loans in the maximum principal amount of $150,000,000 (Revolving B Loans), and Letters of Credit and Swing Line Loans (as defined in the Credit Agreement). The Second Amendment extends the maturity date of the Revolving B Loans from December 22, 2024 to December 22, 2026.

Base Rate Loans (as defined in the Credit Agreement) under the Revolving A Loan and the Swing Line Loans accrue interest at the Base Rate plus the Applicable Rate (as defined in the Credit Agreement) and Term SOFR Loans for the Revolving Loans accrue interest at the rate per annum equal to the sum of Term SOFR for such interest period plus the Applicable Rate (as defined in the Credit Agreement). The Base Rate for any day is a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 0.50%, (b) the rate of interest in effect for such day as publicly announced from time to time by BOA as its prime rate, and (c) the Term SOFR plus 1.0% subject to certain interest rate floors. Repayment of all then outstanding principal, interest, fees and costs is due at the end of the Term (as defined in the Credit Agreement).

With respect to Revolving B Loans (as defined in the Credit Agreement), for any day, the rate per annum is a tiered pricing based upon the Consolidated Debt to Consolidated EBITDA Ratio. The applicable rate for Revolving B Loans that are Base Rate Loans range between 0.20% and 1.15%. and the applicable rate for Revolving B Loans that are Term SOFR/Term SOFR Daily Floating Rate range between 1.20% and 2.15%.

At December 31, 2025, we had $133.5 million in outstanding borrowings under the revolving credit facility. The total availability under the revolving credit facility was $413.4 million as of December 31, 2025, which reflects a reduction for outstanding letters of credit totaling $3.1 million.

Compliance with Debt Covenants and Restrictions. Pursuant to the terms of the Credit Agreement, the Company, is subject to certain loan compliance covenants. The Company was in compliance with all covenants at December 31, 2025. Failure to comply with

Table of Contents

the financial covenants could be considered a default of repayment obligations and, among other remedies, could accelerate payment of any amounts outstanding.

Industrial Revenue Bonds. In October 2021, the Company announced plans to add a third manufacturing facility located in Little Rock, Arkansas (Little Rock). Construction on the new facility began in the second quarter of 2022. In connection with the construction of the new facility, during 2024 the Company and Little Rock entered into an agreement in which Little Rock agreed to issue up to $450 million of its industrial revenue bonds (IRBs) for the purpose of constructing a manufacturing facility. Under the agreement, the Company transferred ownership of the facility to Little Rock and simultaneously leased the related asset from Little Rock. The Company is also the purchaser of the IRBs and, therefore, is the bondholder as well as the borrower/lessee of the Little Rock facility purchased with the IRB proceeds.

Contractual Obligations. Our contractual obligations consist primarily of purchase commitments and operating leases.

Purchase obligations represent supply contracts with raw material vendors and service contracts for hauling raw materials. Open purchase orders written in the normal course of business for goods or services that are provided on demand have been excluded as the timing of which is not certain. As of December 31, 2025, we have purchase obligations under material supply contracts of $25.9 million for the year ending December 31, 2026, $24.6 million in 2027, and $9.7 million in 2028. Our purchase obligations do not currently extend beyond 2028. Please refer to Note 19 to the Consolidated Financial Statements in this filing for additional information on our purchase commitments.

Operating leases represent office space, storage warehouses, manufacturing facilities and certain office and plant equipment under various operating leases, and include operating leases accounted for under Financial Accounting Standards Board Accounting Standards Codification Topic 842 and short-term leases. As of December 31, 2025, we have operating lease liabilities of $12.4 million for the year ending December 31, 2026, $32.2 million for the years 2027 through 2030 and $19.8 million thereafter. Please refer to Note 10 to the Consolidated Financial Statements in this filing for additional information on our operating leases.

The Company believes that its cash on hand and cash generated through operating activities, both over the next 12 months and beyond the next 12 months, should be sufficient to cover purchase obligations and operating leases.

Off-Balance Sheet Arrangements. We do not have off-balance sheet financing arrangements.

Capital and Other Cash Requirements. Our capital expenditure guidance for 2026 is $100 million to $120 million. Our capital allocation priorities for 2026 include expenditures for internal growth opportunities, manufacturing cost reductions, upgrading equipment and support systems, and acquisitions which fit our long-term growth strategy as we continue to evaluate opportunities that would be a good strategic fit for Trex, and return of capital to shareholders.

We believe that cash on hand, cash flows from operations and borrowings expected to be available under our revolving credit facility will provide sufficient funds to enable us to fund planned capital expenditures, make scheduled principal and interest payments, fund the warranty reserve, meet other cash requirements, and maintain compliance with terms of our debt agreements for at least the next 12 months. We currently expect to fund future capital expenditures from operations and borrowings under the revolving credit facility. The actual amount and timing of future capital requirements may differ materially from our estimate depending on the demand for Trex products and new market developments and opportunities. Our ability to meet our cash needs during the next 12 months and thereafter could be adversely affected by various circumstances, including increases in the cost of raw materials and product replacement costs, quality control problems, higher than expected product warranty claims, service disruptions and lower than expected collections of accounts receivable. In addition, any failure to negotiate amendments to our existing debt agreements to resolve any future noncompliance with financial covenants could adversely affect our liquidity by reducing access to revolving credit borrowings needed primarily to fund seasonal borrowing needs. We may determine that it is necessary or desirable to obtain financing through bank borrowings or the issuance of debt or equity securities to address such contingencies or changes to our business plan. Debt financing would increase our level of indebtedness, while equity financing would dilute the ownership of our stockholders. There can be no assurance as to whether, or as to the terms on which, we would be able to obtain such financing, which would be restricted by covenants contained in our existing debt agreements.

NEW ACCOUNTING STANDARDS

New Accounting Standards Recently Adopted.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The guidance requires public entities to disclose additional categories of information related to federal, state, and foreign income taxes and additional details related to reconciling items should they meet a quantitative threshold. The guidance requires disclosure of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and to disaggregate the information by jurisdiction based on quantitative thresholds. The guidance is effective for fiscal year beginning after December 15, 2024. Early adoption was permitted. The Company adopted the standard in the quarterly period ended December 31, 2025. The Company applied the standard retrospectively and accordingly prior periods were adjusted. Adoption of this guidance did not impact consolidated results of operations and financial position.

New Accounting Standards Not Yet Adopted.

In September 2025, the FASB issued ASU No. 2025-06, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)." This guidance clarifies and modernizes when an entity is required to begin capitalizing software costs. Specifically, it requires capitalization when both of the following are met (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. The amendments to this update are effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption of this update is permitted. The amendments to this update may be applied prospectively, retrospectively, or on a modified transition approach. The Company is evaluating this guidance and the impact it may have on its Consolidated Financial Statements upon adoption.

In July 2025, the FASB issued ASU No. 2025-05, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets." This guidance provides an optional practical expedient related to the estimation of expected credit losses for current accounts receivable and contract assets that arise from transactions accounted for under FASB Accounting Standards Codification 606. Specifically, this optional practical expedient allows an entity to assume that current conditions as of the balance sheet date will not change for the remaining life of the asset. The amendments to this update are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption of this update is permitted. The amendments to this update should be applied prospectively. The Company continues to evaluate the guidance and does not believe adoption will have a material impact on its consolidated results of operations or financial position.

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Disaggregation Disclosures.” This guidance requires more detailed disclosure about the types of expenses presented within the expense captions of the financial statements. Specifically, disclosure of purchases of inventory, employee compensation, depreciation, and intangible asset amortization are required on both an interim and annual basis. In addition, a qualitative description of remaining amounts in relevant expense captions which have not separately been disaggregated will be required on an interim and annual basis. On an annual basis, disclosure of an entity’s definition of selling expenses and the amount of selling expenses is required. The amendments to this update are effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption of this update is permitted. The amendments to this update should be applied prospectively to financial statements issued for reporting periods after the effective date of the update or retrospectively to any or all prior periods presented in the financial statements. The Company believes adoption will result in expanded financial statement footnote disclosure but does not believe adoption of this update will have a material impact on its consolidated results of operations. The Company is continuing to evaluate the impacts of the pending adoption. As such, the Company’s preliminary assessments are subject to change.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are subject to market risks from changing interest rates associated with our borrowings. To meet our seasonal working capital needs, we borrow periodically on our variable rate revolving line of credit. At December 31, 2025, we had $133.5 million in debt outstanding under our revolving line of credit. While variable rate debt obligations expose us to the risk of rising interest rates, an increase of 1% in interest rates would not have a material adverse effect on our overall financial position, results of operations or liquidity.

In certain instances, we may use interest rate swap agreements to modify fixed rate obligations to variable rate obligations, thereby adjusting the interest rates to current market rates and ensuring that the debt instruments are always reflected at fair value. We had no interest rate swap agreements outstanding as of December 31, 2025.

Management’s Report on Internal Control Over Financial Reporting

We, as members of management of Trex Company, Inc. (Company), are responsible for establishing and maintaining adequate internal control over financial reporting. The 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 U.S. generally accepted accounting principles. 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 U.S. 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 and procedures may deteriorate.

We assessed the Company’s internal control over financial reporting as of December 31, 2025, based on criteria for effective internal control over financial reporting established in “Internal Control-Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO Framework). Based on this assessment, we concluded that, as of December 31, 2025, our internal control over financial reporting was effective, based on the COSO Framework.

The effectiveness of our internal control over financial reporting as of December 31, 2025, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report, which follows hereafter.

Insider Trading Arrangements. During the quarter ended December 31, 2025, none of our directors or officers (as defined in Rule 16a-1(f) of the Exchange Act) adopted, modified or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) of the Exchange Act or any non-Rule 10b5-1 trading arrangement (as identified in Item 408(c) of Regulation S-K).

Retention Agreement. On February 24, 2026, the Company entered into a Retention Agreement with Prithvi S. Gandhi, the Company’s Senior Vice President, Chief Financial Officer, pursuant to which the Company will award restricted stock units (RSUs) to Mr. Gandhi, with the RSUs vesting only if Mr. Gandhi is actively employed by the Company on February 24, 2029 (the Retention Date). The aggregate value of the RSUs is $750,000. The number of RSUs shall be based upon the closing market price of the stock on February 24, 2026.

The RSUs will be granted pursuant to the Trex Company, Inc. 2023 Stock Incentive Plan.

The Retention Agreement provides that the RSUs shall vest, and the cash payment will be made, in the event of the death or disability of the Recipient, if the Company terminates the Recipient’s employment without “cause”, or if the Recipient resigns for “good reason,” prior to the Recipient achieving the applicable Retention Date. For this purpose, “cause” shall mean (i) Recipient’s willful or grossly negligent misconduct, or subversive, disruptive or insubordinate behavior, that is injurious to the Company or that violates Company policy; (ii) Recipient’s embezzlement or misappropriation of funds or property of the Company; (iii) Recipient’s conviction of a felony or the entrance of a plea of guilty or nolo contendere to a felony; (iv) Recipient’s conviction of any crime involving fraud, dishonesty, moral turpitude or breach of trust or the entrance of a plea of guilty or nolo contendere to such a crime; or (v) Recipient’s willful failure or refusal by Recipient to devote Recipient’s full business time (other than on account of disability or approved leave) and attention to the performance of Recipient’s duties and responsibilities if such breach has not been cured within 15 days after written notice thereof is given to the Recipient by the Board, and “good reason” shall mean (i) a material and adverse change in Recipient’s status or position(s) as an officer or management employee of the Company, including, without limitation, any adverse change in his status or position as an employee of the Company as a result of a material diminution in Recipient’s duties or responsibilities (other than, if applicable, any such change directly attributable to the fact that the Company is no longer publicly owned) or the assignment to Recipient of any duties or responsibilities which are materially inconsistent with such status or position(s) (other than any isolated and inadvertent failure by the Company that is cured promptly upon his giving notice), or any removal of Recipient from or any failure to reappoint or reelect Recipient to such position(s) (except in connection with Recipient’s termination other than for good reason); (ii) a 10% or greater reduction in Recipient’s aggregate base salary and targeted bonus, other than any such reduction proportionately consistent with a general reduction of pay across the executive staff as a group, as an economic or strategic measure due to poor financial performance by the Company; (iii) the failure by the Company or any successor to continue in effect any material employee benefit plan (excluding any equity compensation plan) in which the Recipient is participating (or plans providing the Recipient with similar benefits that are not materially reduced in the aggregate) other than as a result of the normal expiration of any such plan in accordance with its terms; or the taking of any action, or the failure to act, by the Company or any successor which would adversely affect the Recipient’s continued participation in any of such plans on at least as favorable a basis to Recipient or which would materially reduce Recipient’s benefits under any of such plans, or (iv) Company’s requiring Recipient to be based at an office that is both more than 50 miles from where Recipient’s office is located and further from Recipient’s then current residence.

The Board of Directors has implemented this Retention Agreement reflecting their confidence in Mr. Gandhi’s ability to continue to provide outstanding results and encourage him to continue to focus on the current and future growth of the Company.

The foregoing description of the Retention Agreement is qualified in its entirety by reference to the full text of the Retention Agreement, which is filed as Exhibit 10.10 hereto.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Trex Company, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Trex Company, Inc. (the Company) as of December 31, 2025 and 2024, the related consolidated statements of comprehensive income, changes in stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) (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 at 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 U.S. generally accepted accounting principles.

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 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 25, 2026 expressed an unqualified opinion thereon.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company has elected to change its method of accounting for inventories from the last-in, first-out method to the first-in, first-out method, effective October 1, 2025, with retrospective application to all periods presented. Our opinion is not modified with respect to this matter.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s 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 the critical audit matter does not alter in any way our opinion on the consolidated 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.

		Product Warranty Liability
Description of the Matter		At December 31, 2025, the Company’s product warranty liability was $29.7 million. As discussed in Note 19 of the consolidated financial statements, the Company accrues for the estimated cost of product warranty claims at the time revenue is recognized based on such factors as historical claims experience and future claim projections. Management reviews and adjusts these estimates, if necessary, based on the differences between actual experience and historical estimates. Auditing aspects of the product warranty liability was complex and highly judgmental due to the significant estimation of numerous variables required in determining the liability. In particular, the estimate was sensitive to significant assumptions such as the estimated number of future claim counts and costs incurred to settle claims. These assumptions have a significant effect on the product warranty liability.
How We Addressed the Matter in Our Audit		We obtained an understanding, evaluated the design and tested the operating effectiveness of the controls over the Company’s process to estimate the general product warranty liability, including controls over management’s review of the significant assumptions described above. We also tested management’s controls over the completeness and accuracy of the data used in the model. To audit the product warranty liability recorded by management, we performed procedures that included, among others, evaluating the methodology applied and the significant assumptions used in the Company’s calculation. We tested the completeness and accuracy of the claims data used by management. We performed analyses to determine the sensitivity of changes in the significant assumptions described above. We also involved an internal actuarial specialist to assist in our evaluation of the methodology applied and significant assumptions utilized by management to calculate the product warranty liability.

TREX COMPANY, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

BUSINESS AND ORGANIZATION

Trex Company, Inc. (Trex or Company), a Delaware corporation, was incorporated on September 4, 1998. The Company operates in a single reportable segment. The Company’s principal business based on net sales is the manufacture and distribution of high-performance, low-maintenance wood-alternative decking and railing and outdoor living products and accessories, marketed under the brand name Trex®. A majority of its products are manufactured in a proprietary process that combines reclaimed wood fibers and recycled polyethylene. The principal executive offices are located at 2500 Trex Way, Winchester, Virginia 22601, and the telephone number at that address is (540) 542-6300.

CHANGE IN ACCOUNTING PRINCIPLE FOR INVENTORY VALUATION

During the fourth quarter, the Company changed its accounting method of valuing inventory from a last-in, first-out (LIFO) method to a first-in, first-out (FIFO) method. The Company believes this change in accounting method is preferable as it:

•

More accurately reflects the value of inventory on the consolidated balance sheet at each reporting period;

•

Is consistent with how the Company manages its business as it reflects the actual flow of inventory in operations and is consistent with business planning;

•

Is on a more comparable basis with the primary competitors in its industry peer group

The Company has retrospectively applied the effects of the accounting change to all periods presented. The following tables summarize the effect of the accounting change from LIFO to FIFO on impacted line items in the Company’s consolidated financial statements as follows:

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States. The consolidated financial statements include the accounts of the Company.

The Company’s results of operations are affected by a number of factors, including, but not limited to, the cost to manufacture and distribute products, cost of raw materials, inflation, tariffs, consumer spending and preferences, interest rates, the impact of any supply chain disruptions, economic conditions, and/or any adverse effects from global health pandemics and geopolitical conflicts.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments purchased with original maturities of three months or less.

Concentrations and Credit Risk

The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. The Company from time to time may have bank deposits in excess of insurance limits of the Federal Deposit Insurance Corporation. As of December 31, 2025, substantially all deposits are maintained in one financial institution. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk related to its cash and cash equivalents.

The Company routinely assesses the financial strength of its customers and believes that its trade receivables credit risk exposure is limited. Trade receivables are recognized at the amount of revenue recognized on each shipment for Trex products as the Company has an unconditional right to consideration from the customer and payment is due based solely on the passage of time. An estimate of expected credit losses is recognized as a valuation allowance and adjusted each reporting period. The estimate is based on the current expected credit loss model and is determined using an aging schedule, including past events, current conditions and reasonable and supportable forecasts about the future. There was no material valuation allowance recorded as of December 31, 2025 and December 31, 2024.

In the years ended December 31, 2025, 2024, and 2023, sales to certain customers accounted for 10% or more of the Company’s total net sales. For the year ended December 31, 2025, three customers represented approximately 73% of the Company’s total net sales. For the year ended December 31, 2024, three customers represented 81% of the Company’s total net sales. For the year ended December 31, 2023, three customers represented approximately 72% of the Company’s total net sales. No other customer represented 10% or more of the Company’s total net sales. At December 31, 2025, two customers represented 22%, and 21%, respectively, of the Company’s total accounts receivable balance. At December 31, 2024, two customers represented 33% and 32%, respectively, of the Company’s total accounts receivable balance.

For each year ended December 31, 2025, 2024, and 2023, approximately 23.3%, 21.4%, and 26.7%, respectively, of the Company’s materials purchases were purchased from its four largest suppliers.

Inventories

Inventories for the composite decking and railing products at Trex are valued at the lower of cost (first-in, first-out, or FIFO, method) and net realizable value as this method results in a better matching of costs and revenues. The Company periodically reviews its inventory for slow moving or obsolete items and writes down the related products to the lower of cost or net realizable value. The Company’s reserves for estimated slow moving products or obsolescence are not material.

A majority of the products at Trex are made in a proprietary process that combines reclaimed wood fibers and scrap polyethylene. Trex grinds up scrap materials generated from its manufacturing process and inventories deemed no longer salable and reintroduces the reclaimed material into the manufacturing process as a substitute for raw materials. The reclaimed material is valued at the cost of the raw material components of the material.

F-11

Table of Contents

Property, Plant and Equipment

Property, plant and equipment are stated at historical cost. The costs of additions and improvements are capitalized, while maintenance and repairs are expensed as incurred. Cash flows for capital expenditures as reported in cash flows from investing activities in the Consolidated Statements of Cash Flows are adjusted to exclude unpaid amounts accrued at period end. Depreciation is provided using the straight-line method generally over the following estimated useful lives:


Buildings	40 years
Machinery and equipment	3-11 years
Furniture and fixtures	10 years
Forklifts and tractors	5 years
Computer equipment and software	5 years

Leasehold improvements are amortized over the shorter of the lease term or 15 years.

The Company reviews its long-lived assets, including property, plant and equipment, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine the recoverability of its long-lived assets, the Company evaluates the probability that future estimated undiscounted net cash flows will be less than the carrying amount of the long-lived assets. If the estimated cash flows are less than the carrying amount of the long-lived assets, the assets are written down to their fair value. The Company’s estimates of anticipated cash flows and the remaining estimated useful lives of long-lived assets could be reduced in the future. As a result, the carrying amount of long-lived assets could be reduced in the future. Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell.

Leases

The Company leases office space, storage warehouses, training and manufacturing facilities, and certain office and plant equipment under various operating leases. At inception of an arrangement, the Company evaluates, among other things, whether it has the right to control the use of an identified asset in order to determine if the arrangement is or contains a lease. Operating leases are included in operating lease assets, accrued expenses and other current liabilities, and operating lease liabilities in the consolidated balance sheets. Operating leases with an initial term of 12 months or less are not included in the consolidated balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the implicit rates of the Company’s leases are not readily determinable, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company considers instruments with similar characteristics when calculating its incremental borrowing rate. Certain events, such as a modification to the arrangement or a change in the lease term, are assessed by the Company to determine if it is required to reassess estimates and judgments and remeasure the lease liability and ROU asset. The Company reviews its ROU asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. The carrying amount of the ROU asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use of the asset. An impairment loss is measured as the amount by which the carrying amount of the ROU asset exceeds its fair value. The Company’s operating leases have remaining lease terms up to 11 years. Lease terms may include options to extend or terminate the lease when the Company determines that it is reasonably certain it will exercise the option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for separately. Consideration for non-lease components is stated on a stand-alone basis in the applicable agreements.

Fair Value Measurement

Assets and liabilities measured at fair value are measured at the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and classified into one of the following fair value hierarchies:

•

Level 1 – Quoted prices for identical instruments in active markets.

•

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations in which all significant inputs and significant value drivers are observable in active markets.

F-12

Table of Contents

•

Level 3 – Valuations derived from management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

Goodwill

Goodwill represents the excess of cost over net assets acquired resulting from the Company’s 1996 purchase of the Mobil Composite Products Division, the 2011 purchase of the assets of the Iron Deck Corporation, and the 2017 purchase of certain assets and the assumption of certain liabilities of SC Company. The Company evaluates the recoverability of goodwill in accordance with Accounting Standard Codification Topic 350, “Intangibles – Goodwill and Other,” annually or more frequently if an event occurs or circumstances change in the interim that would more likely than not reduce the fair value of the asset below its carrying amount. Goodwill is considered to be impaired when the net book value of the reporting unit exceeds its estimated fair value. Trex has one reporting unit.

In testing for goodwill impairment, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the qualitative assessment indicates that the carrying amount of the reporting unit exceeds its fair value, including goodwill, the Company is then required to perform a quantitative goodwill impairment test. The quantitative goodwill impairment test, used to identify both the existence of impairment and the amount of impairment loss, compares the fair value of its reporting unit with its carrying amount, including goodwill. The fair value of its reporting unit refers to the price that would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

The Company performs the annual impairment testing of its goodwill as of October 31 of each year. For fiscal years 2025, 2024 and 2023, the Company completed its annual impairment test utilizing the qualitative assessment and concluded it was not more likely than not that the fair value of the reporting unit was less than its carrying amount. Qualitative factors the Company considered include events and circumstances such as macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, and other relevant Company-specific events, as applicable.

Product Warranty

The Company warrants that for the applicable warranty period its products, when properly installed, used and maintained, will be free from material defects in workmanship and materials and its decking, cladding, fascia and railing products will not split, splinter, rot or suffer structural damage from termites or fungal decay.

Products sold on or after January 1, 2023: The warranty period for residential use is 50 years for Transcend® decking, 35 years for Select® decking and Universal Fascia, and 25 years for Enhance® decking and Transcend, Select, Enhance and Signature® railing. The warranty period for commercial use is 10 years, excluding Signature railing and Transcend cladding, which each have a warranty period of 25 years. The Company further warrants that Trex Transcend, Trex Enhance and Trex Select decking and cladding and Universal Fascia products will not fade in color from light and weathering exposure more than a certain amount and will be resistant to permanent staining from food and beverage substances or mold and mildew, provided the stain is cleaned within seven days of appearance, for the warranty period referred to above. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price.

Products sold prior to January 1, 2023: The warranty period is 25 years for residential use and 10 years for commercial use. With respect to Trex Signature railing, the warranty period is 25 years for both residential and commercial use. The Company further warrants that Trex Transcend, Trex Enhance, Trex Select and Universal Fascia products will not fade in color more than a certain amount and will be resistant to permanent staining from food substances or mold, provided the stain is cleaned within seven days of appearance, for the warranty period referred to above. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price.

The Company maintains a warranty reserve for the settlement of its product warranty claims. The Company accrues for the estimated cost of product warranty claims at the time revenue is recognized based on such factors as historical claims experience and expected future claims projections. To estimate future claims projections, the Company utilizes actuarial techniques to determine a reasonable possible range of amounts to be paid related to defects covered by our product warranty. The actuarial techniques consider claims received, claims closed, and the amounts paid on claims. Estimates for these elements are quantified using a range of assumptions derived from claim history and consideration of additional factors influencing claim counts or costs incurred to settle claims in order determine the best estimate of future claims for which to record a related liability. Management reviews and adjusts these estimates, if necessary, based on the differences between actual experience and historical estimates.

Treasury Stock

The Company records the repurchase of shares of its common stock at cost. These shares are considered treasury stock, which is a reduction to stockholders’ equity. Treasury stock is included in authorized and issued shares but excluded from outstanding shares.

Revenue Recognition

Trex principally generates revenue from the manufacture and sale of its high-performance, low-maintenance, eco-friendly composite decking and railing products and accessories. Substantially all of its revenues are from contracts with customers, which are individual customer purchase orders of short-term duration of less than one year. Trex satisfies its performance obligations at a point in time. The shipment of each product is a separate performance obligation as the customer is able to derive benefit from each product shipped and no performance obligation remains after shipment. Upon shipment of the product, the customer obtains control over the distinct product and Trex satisfies its performance obligation. Any performance obligation that remains unsatisfied at the end of a reporting period is part of a contract that has an original expected duration of one year or less. Any variable consideration related to the unsatisfied performance obligation is allocated wholly to the unsatisfied performance obligation and recognized when the product ships and the performance obligation is satisfied and is included in “Accrued expenses and other liabilities, Sales and marketing” in Note 8 to these Consolidated Financial Statements.

Stock-Based Compensation

The Company measures stock-based compensation at the grant date of the award based on the fair value. For stock options, stock appreciation rights and time-based restricted stock and time-based restricted stock units, stock-based compensation is recognized on a straight-line basis over the vesting periods of the award. The Company recognizes forfeitures as they occur. For performance-based restricted stock and performance-based restricted stock units, expense is recognized ratably over the performance and vesting period of each tranche based on management’s judgment of the ultimate award that is probable to be paid out based on the achievement of predetermined performance measures. Stock-based compensation expense is included in “Selling, general and administrative expenses” in the accompanying Consolidated Statements of Comprehensive Income.

Income Taxes

The Company recognizes deferred tax assets and liabilities based on the difference between the financial statement basis and tax basis of assets and liabilities using enacted tax laws and statutory tax rates. The Company assesses the likelihood that its deferred tax assets will be realized. Deferred tax assets are reduced by a valuation allowance when, after considering all available positive and negative evidence, it is determined that it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. As of December 31, 2025, the Company has a valuation allowance of $2.2 million against these deferred tax assets related to certain state tax credits. The Company analyzes its position in subsequent reporting periods, considering all available positive and negative evidence, in determining the expected realization of its deferred tax assets.

Research and Development Costs

Research and development costs are expensed as incurred. For the years ended December 31, 2025, 2024, and 2023, research and development costs were $4.2 million, $3.5 million, and $3.3 million, respectively, and have been included in “Selling, general and administrative expenses” in the accompanying Consolidated Statements of Comprehensive Income.

Advertising Costs

The Company expenses its branding and advertising communication costs as incurred. Advertising production costs are deferred and recognized as expense in the period that the related advertisement is first used. For the years ended December 31, 2025, 2024, and 2023, branding expenses, including advertising expenses, were $61.0 million, $53.5 million, and $48.8 million, respectively.

Fair Value of Financial Instruments

The Company considers the recorded value of its financial assets and liabilities, consisting primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities, and debt to approximate the fair value of the respective assets and liabilities on the Consolidated Balance Sheets at December 31, 2025 and 2024.

GOODWILL AND OTHER INTANGIBLE ASSETS, NET

The carrying amount of goodwill at December 31, 2025, and December 31, 2024, was $14.2 million for Trex. For fiscal years 2025, 2024 and 2023, the Company completed its annual impairment test of goodwill for its reporting unit utilizing the qualitative assessment and concluded it was not more likely than not that the fair value of the Company's sole reporting unit was less than its carrying amount.

The Company’s intangible assets, purchased in 2018, 2024, and 2025, consist of domain names and internal use software. Intangible asset amounts were determined based on the estimated economics of the asset and are amortized over the estimated useful lives on a straight-line basis over 15 years for domain names and 10 years for internal use software related to the Company's ERP and other platform tools, which approximates the pattern in which the economic benefits are expected to be received. The Company evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate an impairment.

The following table summarizes the Company's intangible assets as of December 31 (in thousands):

REVENUE FROM CONTRACTS WITH CUSTOMERS

Topic 606 provides a single, comprehensive model for revenue recognition arising from contracts with customers. 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 Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized when or as the Company satisfies the performance obligation. Revenue is recognized at an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring control of the goods or services to a customer.

Trex principally generates revenue from the manufacture and sale of its high-performance, low-maintenance, eco-friendly wood-alternative composite decking and railing products and accessories. Substantially all of its revenues are from contracts with customers, which are purchase orders of short-term duration of less than one year. Its customers, in turn, sell primarily to the residential market, which includes replacement, remodeling and new construction related to outdoor living products. Trex satisfies its performance obligations at a point in time. The shipment of each product is a separate performance obligation as the customer is able to derive benefit from each product shipped and no performance obligation remains after shipment. Upon shipment of the product, the customer obtains control over the distinct product and Trex satisfies its performance obligation. Any performance obligation that remains unsatisfied at the end of a reporting period is part of a contract that has an original expected duration of one year or less. Any variable consideration related to the unsatisfied performance obligation is allocated wholly to the unsatisfied performance obligation and recognized when the product ships and the performance obligation is satisfied and is included in “Accrued expenses and other liabilities, Sales and marketing” in Note 8 to the Consolidated Financial Statements.

For each product shipped, the transaction price by product is specified in the purchase order. The Company recognizes revenue on the transaction price less any amount offered under a sales incentive program. The Company recognizes an account receivable for the amount of revenue recognized as it has an unconditional right to consideration at the time of shipment and payment from the customer is due based solely on the passage of time. The Company receives payments from its customers based on the payment terms applicable to each individual contract and the customer pays in accordance with the billing terms specified in the purchase order, which is less than one year. The related accounts receivables are included in “Accounts receivable, net” in the Consolidated Balance Sheets.

Trex may offer various sales incentive programs throughout the year. It estimates the amount of sales incentive to allocate to each performance obligation, or product shipped, based on direct sales to the customer. The estimate is updated each reporting period, and any changes are allocated to the performance obligations on the same basis as at inception. Changes in estimate allocated to a previously satisfied performance obligation are recognized as a reduction of revenue in the period in which the change occurs under the cumulative catch-up method. In addition to sales incentive programs, Trex may offer payment discounts. It estimates the payment discount that it believes will be taken by the customer based on prior history using the most-likely-amount method of estimation.

Trex pays commissions to certain employees. However, the sales commissions are not directly attributable to identifiable contracts, are discretionary in nature and are based on other factors not related to obtaining a contract, such as individual performance, profitability of the entity, annual sales targets, etc. These costs are included in selling, general and administrative expenses as incurred. Trex does not grant contractual product return rights to customers other than pursuant to its assurance product warranty (see related disclosure on product warranties in Note 19, “Commitments and Contingencies”). Trex accounts for all shipping and handling fees invoiced to the customer in net sales and the related costs in cost of sales.

For each year in the three years ended December 31, 2025, December 31, 2024, and December 31, 2023 revenue was recognized at a point in time under variable consideration contracts.

STOCK-BASED COMPENSATION

At the annual meeting of stockholders of the Company held on May 4, 2023, the Company’s stockholders approved the Trex Company, Inc. 2023 Stock Incentive Plan (Plan). The Company’s board of directors unanimously approved the Plan on April 10, 2023, subject to stockholder approval. The Plan amends and restates in its entirety the Trex Company, Inc. 2014 Stock Incentive Plan (2014 Plan), which was last approved by the Company’s stockholders at the annual meeting held on April 30, 2014. The Plan, which will be administered by the compensation committee of the board of directors, provides for the grant of stock options, restricted stock, restricted stock units, stock appreciation rights and unrestricted stock, which are referred to collectively as “awards.” Awards may be granted under the Plan to officers, directors (including non-employee directors) and other employees of the Company or any subsidiary thereof, to any adviser, consultant, or other provider of services to the Company (and any employee thereof), and to any other individuals who are approved by the board of directors as eligible to participate in the Plan. Only employees of the Company or any subsidiary thereof are eligible to receive incentive stock options. Subject to certain adjustments as provided in the Plan, the total aggregate number of shares of common stock that may be granted under the Plan is 4,000,000 shares. As of December 31, 2025, the total number of shares available for future grants was 3,674,799.

Table of Contents

The Company recognizes stock-based compensation expense ratably over the period from grant date to the earlier of (1) the vesting date of the award, or (2) the date the grantee is eligible to retire without forfeiting the award. For performance-based restricted stock units, expense is recognized ratably over the performance and vesting period of each tranche based on management’s judgment of the ultimate award that is probable to be paid out based on the achievement of the predetermined performance measures. For the employee stock purchase plan, compensation expense is recognized related to the discount on purchases. The following table summarizes the Company’s stock-based compensation expense (in thousands):

Stock-based compensation expense is included in “Selling, general and administrative expenses” in the accompanying Consolidated Statements of Comprehensive Income.

Time-Based Restricted Stock Units

The fair value of time-based restricted stock units is determined based on the closing price of Trex shares on the grant date. Time-based restricted stock units vest based on the terms of the awards. Unvested time-based restricted stock units are generally forfeitable upon the resignation of employment or termination of employment with cause. The total fair value of vested time-based restricted stock units granted in the years ended December 31, 2025, 2024, and 2023 was $4.7 million, $4.6 million, and $4.7 million, respectively. At December 31, 2025, there was $7.2 million of total compensation expense related to unvested time-based restricted stock units remaining to be recognized over a weighted-average period of approximately 2.0 years.

Time-based restricted stock unit activity under the Plan and all predecessor stock incentive plans is as follows:


	Time-based Restricted Stock Unit			Weighted- Average Grant Price Per Share
Nonvested at December 31, 2022		110,635		$	61.28

Performance-based Restricted Stock Units

The fair value of performance-based restricted stock units is determined based on the closing price of Trex shares on the grant date. Unvested performance-based restricted stock units are generally forfeitable upon the resignation of employment or termination of employment with cause. The performance-based restricted shares units have a three-year vesting period, vesting one-third each year based on target earnings before interest, taxes, depreciation, and amortization (EBITDA) for 1 year, cumulative 2 years and cumulative 3 years, respectively. The number of shares that will vest, with respect to each vesting, will be between 0% and 200% of the target number of shares. At December 31, 2025, 2024, and 2023 there was $2.1 million, $3.6 million, $4.3 million, respectively, of total compensation expense related to unvested performance-based restricted stock units remaining to be recognized over a weighted-average period of approximately 1.9 years.

Stock Appreciation Rights

SARs are granted with a grant price equal to the closing market price of the Company’s common stock on the date of grant. These awards expire ten years after the date of grant and vest based on the terms of the individual awards. The SARs are generally forfeitable upon the resignation of employment or termination of employment with cause. The Company recognizes forfeitures as they occur. The Company recognizes compensation cost on a straight-line basis over the vesting period for the award.

As of December 31, 2025, there was $1.5 million of unrecognized compensation cost related to SARs. The fair value of each SAR is estimated on the date of grant using a Black-Scholes option-pricing model. For SARs issued in the years ended December 31, 2025, December 31, 2024, and December 31, 2023, respectively, the assumptions shown in the following table were used:


	Year Ended December 31,
	2025			2024			2023
Dividend yield		0	%		0	%		0	%
Average risk-free interest rate		4.3	%		4.3	%		4.0	%
Expected term (years)		5			5			5
Expected volatility		51.4	%		51.2	%		49.5	%

Dividend Yield. Trex has never paid cash dividends on its common stock.

Average Risk-Free Interest Rate. The Company uses the U.S. Treasury rate having a term that most closely resembles the expected term of the option.

Expected Term. The expected term is the period of time that the SARs granted are expected to remain unexercised. SARs granted during the years ended December 31, 2025, December 31, 2024, and December 31, 2023, had a maximum term of ten years. The Company used historical exercise behavior with further consideration given to the class of employees to whom the equity awards were granted to estimate the expected term of the SAR.

Expected Volatility. Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company has used the historical volatility over the average expected term of the options granted as the expected volatility.

The weighted-average grant date fair value of SARs granted during the years ended December 31, 2025, December 31, 2024, and December 31, 2023, was $33.06, $44.83, and $27.19, respectively.

Employee Stock Purchase Plan

The Company has an employee stock purchase plan (ESPP) that permits eligible employees to purchase shares of common stock of the Company at a purchase price which is the lesser of 85% of the market price on either the first day of the calendar quarter or the last day of the calendar quarter. Eligible employees may elect to participate in the plan by authorizing payroll deductions of up to 15% of gross compensation for each payroll period.

The Company recognizes deferred tax assets and liabilities based on the difference between the financial statement basis and tax basis of assets and liabilities using enacted tax laws and statutory tax rates. In accordance with accounting standards, the Company assesses the likelihood that its deferred tax assets will be realized. Deferred tax assets are reduced by a valuation allowance when, after considering all available positive and negative evidence, it is determined that it is more likely than not that some portion, or all, of the deferred tax asset will not be realized, primarily certain state income tax credits. As of December 31, 2025, the Company had a valuation allowance of $2.2 million against deferred tax assets it estimates will not be realized. The Company will analyze its position in subsequent reporting periods, considering all available positive and negative evidence, in determining the expected realization of its deferred tax assets.

The Company recognizes interest and penalties related to tax matters as a component of “Selling, general and administrative expenses” in the accompanying Consolidated Statements of Comprehensive Income. As of December 31, 2025, the Company has identified no uncertain tax position and, accordingly, has not recorded any unrecognized tax benefits or associated interest and penalties.

The Company operates in multiple tax jurisdictions and, in the normal course of business, its tax returns are subject to examination by various taxing authorities. Such examinations may result in future assessments by these taxing authorities, and the Company has accrued a liability when it believes that it is not more likely than not that it will realize the benefits of tax positions that it has taken or for the amount of any tax benefit that exceeds the cumulative probability threshold in accordance with accounting standards. As of December 31, 2025, for certain tax jurisdictions, tax years 2021 through 2025 remain subject to examination. The Company believes that adequate provisions have been made for all tax returns subject to examination. Sales made to foreign distributors are not taxable in any foreign jurisdictions as the Company does not have a taxable presence.

SEGMENT INFORMATION

The Company operates in one reportable segment, with resource allocation and assessment of financial performance based on a consolidated basis.

Trex manufactures composite decking and railing and related outdoor living products marketed under the brand name Trex®. The products are sold to its distributors and two national retailers who, in turn, sell primarily to the residential market, which includes replacement, remodeling and new construction.

F-26

Table of Contents

The Company’s reportable segments are determined in accordance with its internal management structure, which is based on operations. The Company has identified its President and Chief Executive Officer as the Chief Operating Decision Maker (CODM). The Company’s CODM has final authority over resource allocation decisions and performance assessments and makes key operating decisions. The primary objective of the CODM is to optimize positive Company-wide performance and financial results. The CODM evaluates segment performance primarily based on net income and net sales. The CODM uses net income to assess performance and allocate resources as this measure provides insight into all aspects of the segment’s operations and overall success of the segment for a given period. The CODM also uses net sales to assess performance and allocate resources as this measure represents the amount of business the segment engaged in during a given period of time, is an indicator of market growth and acceptance of segment products, and represents the segment’s customers’ spending habits along with the amount of product the segment sells relative to its competitors. In addition, the CODM reviews significant segment expenses with a primary focus on cost of sales and total selling, general, and administrative expenses. These measures are provided in the accompanying Consolidated Statements of Comprehensive Income. Segment assets are reported on the Consolidated Balance Sheets.

SEASONALITY

The operating results for Trex have historically varied from quarter to quarter. Seasonal, erratic, or prolonged adverse weather conditions may reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practice, Trex has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs.

COMMITMENTS AND CONTINGENCIES

Legal Matters

Purchase Commitments

The Company fulfills requirements for raw materials under both purchase orders and supply contracts. In the year ended December 31, 2025, the Company purchased reclaimed wood fiber requirements under purchase orders and long-term supply commitments. All of the Company’s scrap polyethylene, aluminum and stainless-steel purchases are under short-term supply contracts that average approximately one year, for which pricing is negotiated as needed, or under purchase orders that do not involve long-term supply commitments.

The wood and polyethylene supply contracts generally provide that the Company is obligated to purchase all wood or polyethylene a supplier provides, if the wood or polyethylene meets certain specifications. The amount of wood and polyethylene the Company is required to purchase under these contracts varies with the production of its suppliers and, accordingly, is not fixed or determinable. As of December 31, 2025, the Company has purchase commitments under material supply contracts of $25.9 million for the year ending December 31, 2026, and a total of $34.3 million for the years ending December 31, 2027 through 2028. Our purchase commitments do not currently extend beyond 2028.

Product Warranty

The Company warrants that for the applicable warranty period its Trex products, when properly installed, used and maintained, will be free from material defects in workmanship and materials and its decking, cladding, fascia and railing products will not split, splinter, rot or suffer structural damage from termites or fungal decay.

Products sold on or after January 1, 2023: The warranty period for residential use is 50 years for Transcend® decking, 35 years for Select® decking and Universal Fascia, and 25 years for Enhance® decking and Transcend, Select, Enhance and Signature® railing. The warranty period for commercial use is 10 years, excluding Signature railing and Transcend cladding, which each have a warranty period of 25 years. The Company further warrants that Trex Transcend, Trex Enhance and Trex Select decking and cladding and Universal Fascia products will not fade in color from light and weathering exposure more than a certain amount and will be resistant to permanent staining from food and beverage substances or mold and mildew, provided the stain is cleaned within seven days of appearance, for the warranty period referred to above. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price.

amount and will be resistant to permanent staining from food substances or mold, provided the stain is cleaned within seven days of appearance, for the warranty period referred to above. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price.

The Company maintains a warranty reserve for the settlement of its product warranty claims. The Company accrues for the estimated cost of product warranty claims at the time revenue is recognized based on such factors as historical claims experience and future claims experience. To estimate our future claims experience, the Company utilizes actuarial techniques to determine a reasonable possible range of amounts to be paid related to defects covered by our product warranty. The actuarial techniques consider claims received, claims closed, and the corresponding amounts paid. Estimates for these elements are quantified using a range of assumptions derived from claim history and consideration of additional factors influencing claim counts or costs incurred to settle claims in order determine the best estimate of future claims for which to record a related liability. Management reviews and adjusts these estimates, if necessary, based on the differences between actual experience and historical estimates.

The Company monitors claims activity each quarter for indications that its estimates require revision.

The Company’s analysis is based on currently known facts and a number of assumptions, as discussed above, and current expectations. Projecting future events such as the number of claims to be received, the number of claims that will require payment and the costs associated with settling claims could cause the actual warranty liability to be higher or lower than projected, which could materially affect the Company’s financial condition, results of operations or cash flows. The Company estimates that a 10% change in the expected future claims activity may result in approximately a $3.0 million change in the estimate of its product warranty reserve.

The Trex product warranty reserve activity consisted of the following, and is included in Accrued warranty and Non-current accrued warranty in the Consolidated Balance Sheets (in thousands):


	Year Ended December 31, 2025
	Trex Product Warranty
Beginning balance, January 1	$	22,835
Provisions and changes in estimates		14,954
Settlements made during the period		(8,049	)
Ending balance, December 31	$	29,740


	Year Ended December 31, 2024
	Trex Product Warranty
Beginning balance, January 1	$	22,178
Provisions and changes in estimates		9,725
Settlements made during the period		(9,068	)
Ending balance, December 31	$	22,835

As of December 31, 2025 the Company's reserve of $29.7 million is within the estimated range of possible loss associated with product warranty claims. The Company’s estimate of the range of possible loss for product warranty claims associated with product sold through December 31, 2025 is between $24.8 million and $45.6 million. The company utilized an actuary in calculating a range of possible loss for product warranty claims. Actual experience could exceed the range due to uncertainty associated with the future number of claims expected to be closed with some payment and estimates of the costs associated with servicing those claims.

Industrial Revenue Bonds

F-28

Table of Contents

during 2024 the Company and Little Rock entered into an agreement in which Little Rock agreed to issue up to $450 million of its industrial revenue bonds (IRBs) for the purpose of constructing a manufacturing facility. Under the agreement, the Company transferred ownership of the facility to Little Rock and simultaneously leased the related asset from Little Rock. The Company is also the purchaser of the IRBs and, therefore, is the bondholder as well as the borrower/lessee of the Little Rock facility purchased with the IRB proceeds.

How diversified is Trex’s (TREX) customer base and distribution network?

Trex sells primarily through wholesale distributors and major home centers.
