[10-Q] Trex Company, Inc. Quarterly Earnings Report

Rhea-AI Filing Summary

Trex Company’s Q2-25 10-Q shows mixed performance. Net sales rose 3% YoY to $387.8 m, but gross margin compressed to 40.8% (-390 bp) as start-up costs at the new Arkansas plant and lower production efficiency offset volume gains. Operating income fell 12.4% to $102.4 m; net income dropped 12.7% to $75.9 m, driving diluted EPS down to $0.71 (vs $0.80).

For the first half, revenue declined 3% to $727.8 m and EPS fell 21.6% to $1.27. SG&A expanded 60 bp to 15.4% of sales on higher branding, personnel and Arkansas ramp-up expenses. Operating cash flow rebounded to $95.7 m (vs $19.6 m) thanks to a $65 m inventory drawdown, but heavy capex of $126.3 m—mostly for the Arkansas facility—drove negative free cash flow.

The balance sheet shows cash of $5.5 m, inventories $141.8 m (-31% YTD) and revolver borrowings up to $245.4 m at 5.23% interest, leaving $304.6 m undrawn. Equity rose 16% to $989.3 m on retained earnings. The company remained covenant-compliant.

Key takeaways:

• Volume recovery but margin pressure from production changes and start-up costs.
• Channel inventory strategy reduced H1 revenue but improved working-capital metrics.
• Arkansas plant supports long-term capacity; near-term weighs on costs and capex.

Insights

Sell-Side Financial Analyst

TL;DR – Modestly negative: higher sales overshadowed by margin erosion and heavier leverage.

Trex eked out top-line growth, signalling resilient composite-deck demand, but 390 bp gross-margin deterioration cut operating leverage. Arkansas start-up costs and Enhance process tweaks explain most of the hit, yet they highlight the execution risk of new capacity. SG&A inflation lifted opex ratio to 15.4%, re-pressurising profitability. Cash conversion improved dramatically on inventory burn, but the company financed capex largely with the revolver; net debt therefore climbed. With EBITDA down 9% for the quarter and 19% YTD, valuation multiples may compress until margins stabilise. I view the filing as impactful and slightly negative for near-term sentiment.

Portfolio Manager – Small-Cap Growth

TL;DR – Near-term pain, long-term capacity build; hold bias.

The quarter underscores Trex’s strategy pivot: sacrifice margin and cash for Arkansas expansion and channel reset. Inventory rightsizing boosts working capital, but higher debt and capex dent free cash flow. Nonetheless, the 50-year residential warranty, single-segment focus and strong brand leave the structural thesis intact. If Arkansas normalises and housing improves in 2H-25, operating leverage could rebound. I label the disclosure impactful yet broadly neutral for long-term holders—maintain position but monitor margin recovery.

TREX COMPANY, INC.

Notes to Condensed Consolidated Financial Statements

For the Six Months Ended June 30, 2025 and June 30, 2024

(Unaudited)

1.BUSINESS AND ORGANIZATION

Trex Company, Inc. (Trex or Company), is the world’s largest manufacturer of high-performance, low-maintenance wood-alternative decking and railing and outdoor living products and accessories, marketed under the brand name Trex®, with more than 30 years of product experience. A majority of its products are manufactured in a proprietary process that combines reclaimed wood fibers and scrap polyethylene. The Company is incorporated in Delaware. The principal executive offices are located at 2500 Trex Way, Winchester, Virginia 22601, and the telephone number at that address is (540) 542-6300. The Company operates in a single reportable segment.

2.BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and U.S. Securities and Exchange Commission instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal and recurring adjustments, except as otherwise described herein) considered necessary for a fair presentation have been included in the accompanying unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements include the accounts of the Company for all periods presented.

The unaudited consolidated results of operations for the three and six months ended June 30, 2025, are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2025. 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.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report of Trex Company, Inc. on Form 10-K for the year ended December 31, 2024, as filed with the U.S. Securities and Exchange Commission.

3.RECENTLY ADOPTED ACCOUNTING STANDARDS

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The guidance requires disclosure of significant segment expenses which are regularly provided to the chief operating decision maker (CODM), the composition of and amount of other segment items, the CODM’s title and position within the organization, and how the CODM uses the reported measure(s) of segment’s profit or loss to assess the performance of the segment. In addition, on an interim basis, all segment profit or loss and asset disclosures currently required on an annual basis must be reported, as well as those required by Topic 280. The guidance allows for multiple measures of a segment’s profit or loss to be reported. Entities which have a single reportable segment must apply Topic 280 in its entirety. The guidance was effective for fiscal years beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. Early adoption was permitted. Entities are required to apply the amendments of this update retrospectively for all prior periods presented in the financial statements. The Company adopted the standard in the quarterly period ended December 31, 2024. 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.

4.NEW ACCOUNTING STANDARDS NOT YET ADOPTED

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

6

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 adoption.

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 annual reporting periods beginning after December 15, 2024. Early adoption was permitted. The guidance should be applied on a prospective basis; retrospective application is permitted. The Company does not expect adoption of the guidance to have a material effect on its consolidated results of operations and financial position.

5.INVENTORIES

Inventories valued at LIFO (last-in, first-out), consist of the following (in thousands):

		June 30, 2025				December 31, 2024
Finished goods		$	118,903			$	183,670
Raw materials			72,610				73,281
Total FIFO (first-in, first-out) inventories			191,513				256,951
Reserve to adjust inventories to LIFO value			(49,669	)			(49,669	)
Total LIFO inventories		$	141,844			$	207,282

The Company utilizes the LIFO method of accounting, which generally provides for the matching of current costs with current revenues. However, under the LIFO method, reductions in annual inventory balances may cause a portion of the Company’s cost of sales to be based on historical costs rather than current year costs (LIFO liquidation). Reductions in interim inventory balances expected to be replenished by year-end do not result in a LIFO liquidation. Accordingly, interim LIFO calculations are based, in part, on management’s estimates of expected year-end inventory levels and costs and may differ from actual results. Since inventory levels and costs are subject to factors beyond management’s control, interim results are subject to the final year-end LIFO inventory valuation. As of June 30, 2025, management estimates that inventory balances will be replenished by year-end and there were no LIFO inventory liquidations or related impact on cost of sales in the six months ended June 30, 2025.

6.PREPAID EXPENSES AND OTHER ASSETS

Prepaid expenses and other assets consist of the following (in thousands):

		June 30, 2025				December 31, 2024
Prepaid expenses		$	14,371			$	21,353
Other			500				625
Total prepaid expenses and other assets		$	14,871			$	21,978

7.GOODWILL AND OTHER INTANGIBLE ASSETS, NET

The carrying amount of goodwill at June 30, 2025, and December 31, 2024, was $14.2 million. The Company’s intangible assets consist of domain names and internal use software. At June 30, 2025, and December 31, 2024, intangible assets were $16.1 million and $10.6 million and accumulated amortization was $3.0 million and $2.8 million, respectively. Intangible assets 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, 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. Intangible asset amortization expense for the six months ended June 30, 2025, and June 30, 2024, was $0.2 million and $0.2 million, respectively.

8.ACCRUED EXPENSES AND OTHER LIABILITIES

9.DEBT

Revolving Credit Facility

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 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 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).

8

Indebtedness on and after October 10, 2024. On October 10, 2024, the Company, 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 the Company 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%.

The Company had $245.4 million in borrowings outstanding under its revolving credit facility and available borrowing capacity of $304.6 million at June 30, 2025. The weighted average interest rate on the revolving credit facility was 5.23% as of June 30, 2025.

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 as of June 30, 2025. Failure to comply with the financial covenants could be considered a default of repayment obligations and, among other remedies, could accelerate payment of any amounts outstanding.

10.LEASES

The Company leases manufacturing and training facilities, storage warehouses, office space, and certain plant equipment under various operating leases. The Company’s operating leases have remaining lease terms of up to 10 years. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

For the six months ended June 30, 2025 and June 30, 2024, total operating lease expense was $6.0 million and $4.5 million, respectively. The weighted average remaining lease term at June 30, 2025 and December 31, 2024 was 5.9 years and 6.3 years, respectively. The weighted average discount rate at June 30, 2025 and December 31, 2024 was 4.63% and 4.57%, respectively.

The following table includes supplemental cash flow information for the six months ended June 30, 2025 and June 30, 2024, and supplemental balance sheet information at June 30, 2025 and December 31, 2024 related to operating leases (in thousands):

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. During the six months ended June 30, 2025, Trex did not repurchase any shares of its outstanding common stock under the 2023 Stock Repurchase Program.

13.REVENUE FROM CONTRACTS WITH CUSTOMERS

The Company 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. The Company 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, is 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 Condensed Consolidated Financial Statements. For the three months ended June 30, 2025 and June 30, 2024, the Company’s net sales were $387,801 and $376,470, respectively. For the six months ended June 30, 2025 and June 30, 2024, the Company's net sales were $727,794 and $750,105, respectively. During these periods, revenues were recognized at a point in time upon transfer of its outdoor living products under variable consideration contracts into the building products market.

14.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, which is 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 number of shares of common stock available for future grants under the Plan is 3,657,745 shares.

The following table summarizes the Company’s stock-based compensation grants for the six months ended June 30, 2025:

		Stock Awards Granted				Weighted- Average Grant Price Per Share
Time-based restricted stock units			70,320			$	66.54
Performance-based restricted stock units (a)			102,049			$	64.85
Stock appreciation rights			46,126			$	66.67

(a)Includes 80,196 of target performance-based restricted stock unit awards granted during the six months ended June 30, 2025, and adjustments of 1,093, and 20,760 to grants due to the actual performance level achieved for restricted stock and restricted stock units awarded in 2024 and 2023, respectively.

11

The fair value of each SAR is estimated on the date of grant using a Black-Scholes option-pricing formula. For SARs issued in the six months ended June 30, 2025 and June 30, 2024, the data and assumptions shown in the following table were used:

		Six Months Ended June 30, 2025				Six Months Ended June 30, 2024
Weighted-average fair value of grants		$	33.06			$	44.83
Dividend yield			0	%			0	%
Average risk-free interest rate			4.3	%			4.3	%
Expected term (years)			5				5
Expected volatility			51.4	%			51.2	%

The Company recognizes stock-based compensation expense ratably over the period from the 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 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 likely 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. Stock-based compensation expense is included in “Selling, general and administrative expenses” in the Condensed Consolidated Statements of Comprehensive Income. The following table summarizes the Company’s stock-based compensation expense (in thousands):

		Three Months Ended June 30,								Six Months Ended June 30,
		2025				2024				2025				2024
Stock appreciation rights		$	330			$	408			$	624			$	680
Time-based restricted stock and restricted stock units			1,578				1,452				2,404				2,526
Performance-based restricted stock and restricted stock units			967				1,919				2,106				3,561
Employee stock purchase plan			59				60				113				225
Total stock-based compensation		$	2,934			$	3,839			$	5,247			$	6,992

Total unrecognized compensation cost related to unvested awards as of June 30, 2025 was $15.3 million. The cost of these unvested awards is being recognized over the requisite vesting period of each award.

15.INCOME TAXES

The Company’s effective tax rate for the six months ended June 30, 2025 and June 30, 2024, was 25.9% and 25.4%, which resulted in income tax expense of $47.7 million and $59.9 million, respectively.

During the six months ended June 30, 2025 and June 30, 2024, the Company realized $(0.1) million and $0.7 million, respectively, of excess tax expense and excess tax benefit from stock-based awards and recorded a corresponding expense and benefit to income tax expense.

The Company analyzes its deferred tax assets each reporting period, considering all available positive and negative evidence in determining the expected realization of those deferred tax assets. As of June 30, 2025, the Company maintains a valuation allowance of $2.6 million against deferred tax assets primarily related to state tax credits it estimates will expire before they are realized.

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 accrues a liability when it believes that it is more likely than not that benefits of tax positions will not be realized. The Company believes that adequate provisions have been made for all tax returns subject to examination. As of June 30, 2025, for certain tax jurisdictions tax years 2020 through 2024 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 jurisdiction as the Company does not have a taxable presence in any foreign jurisdiction.

On July 4, 2025, H.R.1 - One Big Beautiful Bill Act (Act) was enacted into law. The Act includes several changes to the U.S. corporate income tax framework. The Company has completed a preliminary assessment of the Act’s provisions and determined that they will not have a material impact on the Company’s effective tax rate or income tax expense for the year ended December 31,

12

2025. The Company will continue to monitor any regulatory guidance related to the Act and assess its potential effects on future reporting periods.

16.SEGMENT INFORMATION

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

Trex Residential 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.

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 Condensed Consolidated Statements of Comprehensive Income. Segment assets are reported on the Condensed Consolidated Balance Sheets.

17.SEASONALITY

The operating results for Trex have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift sales of its products to a later period or decrease overall sales in affected locations. 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.

18.COMMITMENTS AND CONTINGENCIES

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 estimated future claims. Management reviews and adjusts these estimates, if necessary, based on the differences between actual

13

experience and historical estimates. Additionally, the Company accrues for warranty costs associated with occasional or unanticipated product quality issues if a loss is probable and can be reasonably estimated, as necessary.

The Company continues to receive and settle claims for decking products manufactured at its Nevada facility prior to 2007 that exhibit surface flaking and maintains a warranty reserve to provide for the settlement of these claims. Estimating the warranty reserve for surface flaking claims requires management to estimate the number of claims to be settled with payment and the average cost to settle each claim. The Company monitors surface flaking claims activity each quarter for indications that its estimates require revision.

The Company believes its product warranty and surface flaking reserves at June 30, 2025 are sufficient to cover future warranty obligations. The following is a reconciliation of the Company’s product warranty and surface flaking reserves (in thousands):

		Six Months Ended June 30, 2025
		Product Warranty				Surface Flaking				Total
Beginning balance, January 1		$	15,596			$	7,239			$	22,835
Provisions and changes in estimates			6,705				—				6,705
Settlements made during the period			(3,099	)			(690	)			(3,789	)
Ending balance, June 30		$	19,202			$	6,549			$	25,751

		Six Months Ended June 30, 2024
		Product Warranty				Surface Flaking				Total
Beginning balance, January 1		$	12,066			$	10,112			$	22,178
Provisions and changes in estimates			4,668				—				4,668
Settlements made during the period			(2,459	)			(680	)			(3,139	)
Ending balance, June 30		$	14,275			$	9,432			$	23,707

Legal Matters

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.

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. 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 Condensed 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 Condensed Consolidated Balance Sheets. As of June 30, 2025, the gross asset and liability associated with the IRBs was $450 million.

OPERATIONS AND PRODUCTS

Trex is the world’s largest manufacturer of high-performance composite decking and railing products and a leader in outdoor living products, which are marketed under the brand name Trex® and manufactured in the United States. With more than 30 years of product experience, we offer a comprehensive set of aesthetically appealing and durable, low-maintenance product offerings in the decking, railing, fencing and outdoor lighting categories. A majority of the products are eco-friendly and leverage recycled and reclaimed materials to the extent possible. Trex decking is made in a proprietary process that combines reclaimed wood fibers and recycled polyethylene film, making Trex one of the largest recyclers of plastic film in North America. In addition to resisting fading and surface staining, Trex products require no sanding and sealing, resist moisture damage, provide a splinter-free surface and do not require chemical treatment against rot or insect infestation. 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. Special characteristics (including resistance to splitting, the ability to bend, and ease and consistency of machining and finishing)

15

facilitate installation, reduce contractor call-backs and afford consumers a wide range of design options. Trex products are sold to distributors and home centers for final resale primarily to the residential market.

Trex offers the following products:

Capital expenditures. During the six months ended June 30, 2025, our capital expenditures were $126.3 million primarily related to $97.6 million for the Arkansas manufacturing facility, $5.9 million in cost reduction initiatives, and $7.4 million in capacity expansion in our existing facilities and safety, environmental and general support.

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. Trex operating results have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home and commercial improvement and residential and commercial construction and can shift sales of our products to a later period or decrease overall sales in affected locations. As part of our normal business practice and consistent with industry practice, we have historically provided our distributors and dealers of our Trex products incentives to build inventory levels before the start of the prime deck-building season to ensure adequate availability of our product to meet anticipated seasonal consumer demand and to enable production planning. These incentives include payment discounts, favorable payment terms, 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 our incentive programs can significantly 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 material costs, direct labor costs, manufacturing costs, subcontract costs and freight. Raw material costs generally include the costs to purchase and transport reclaimed wood fiber, reclaimed polyethylene, pigmentation for coloring our products, and commodities used in the production of railing and staging. 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.

Less than 5% of our cost of sales is projected to be impacted by tariffs. The majority of 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 higher levels of existing pre-tariff inventory and supplier negotiations.

Selling, General and Administrative Expenses. The largest component of selling, general and administrative expenses is personnel related costs, which includes 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. 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 may vary from quarter to quarter due, in part, to the seasonality of our business.

Below is the discussion and analysis of our operating results and material changes in our operating results for the three months ended June 30, 2025 (2025 quarter) compared to the three months ended June 30, 2024 (2024 quarter), and for the six months ended June 30, 2025 (2025 six-month period) compared to the six months ended June 30, 2024 (2024 six-month period).

Gross profit as a percentage of net sales, gross margin, was 40.8% in the 2025 quarter compared to 44.7% in the 2024 quarter. The decrease was primarily the result of lower production year over year as we level load our facilities, inefficiencies associated with start-up costs at our Arkansas facility, and changes to our production process driven by refinements made to our Enhance® decking. The higher costs due to the production refinements will not continue into the third quarter.

Selling, general and administrative expenses increased $4.5 million to $55.7 million, or 14.4% of net sales, in the 2025 quarter. The increase primarily related to increases of $3.3 million in branding, $1.1 million in personnel related expenses, $0.6 million in Arkansas start-up costs, and $0.5 million in facilities and support, partially offset by decreases in other areas.

__________________________

1EBITDA 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 it facilitates performance comparison between the Company and its competitors. Management considers EBITDA to be an important supplemental indicator of our core operating performance because it eliminates interest, income taxes, and depreciation and amortization charges to net income or loss. In relation to competitors, EBITDA eliminates differences among companies in capitalization and tax structures, capital investment cycles and ages of related assets. For these reasons, management believes that EBITDA provides important information regarding the operating performance of the Company. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP and are not meant to be considered superior to or a substitute for our GAAP results.

Total net sales decreased by $22.3 million, or 3%, in the 2025 six-month period compared to the 2024 six-month period.

Total EBITDA decreased 18.7% to $214.1 million for the 2025 six-month period compared to $263.5 million for the 2024 six-month period. The decrease in EBITDA was driven primarily by lower net sales and gross profit.

LIQUIDITY AND CAPITAL RESOURCES

We finance operations and growth primarily with cash flows from operations, borrowings under our revolving credit facilities, operating leases and normal trade credit terms from operating activities. At June 30, 2025, we had $5.5 million of cash and cash equivalents.

Sources and Uses of Cash. The following table summarizes our cash flows from operating, investing and financing activities (in thousands):

		Six Months Ended June 30,
		2025				2024
Net cash provided by operating activities		$	95,739			$	19,641
Net cash used in investing activities			(130,987	)			(73,096	)
Net cash provided by financing activities			39,479				52,668
Net increase (decrease) in cash and cash equivalents		$	4,231			$	(787	)

Operating Activities

Cash provided by operations was $95.7 million during the 2025 six-month period compared to cash provided by operations of $19.6 million during the 2024 six-month period. The $76.1 million increase in cash provided by operating activities was primarily related to a decrease in inventories in the six months ended June 30, 2025 compared to the six months ended June 30, 2024. The decrease in inventories is the result of lower production in 2025.

Investing Activities

Capital expenditures in the 2025 six-month period were $126.3 million primarily related to $97.6 million for the Arkansas manufacturing facility, $5.9 million in cost reduction initiatives, and $7.4 million in capacity expansion in our existing facilities and safety, environmental and general support.

21

Financing Activities

Net cash provided by financing activities in the 2025 six-month period consisted primarily of net borrowings under our line of credit.

Stock Repurchase Program. On May 4, 2023, the Trex Board of Directors adopted a new stock repurchase program of up to 10.8 million shares of its outstanding common stock, and terminated the existing Stock Repurchase Program. This repurchase program has no set expiration date. During the six months ended June 30, 2025, the Company did not repurchase any shares of its common stock under the 2023 Stock Repurchase Program.

Revolving Credit Facility

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 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 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

22

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 June 30, 2025, we had $245.4 million in outstanding borrowings under the revolving credit facility and borrowing capacity under the facility of $304.6 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 June 30, 2025. Failure to comply with the financial covenants could be considered a default of repayment obligations and, among other remedies, could accelerate payment of any amounts outstanding.

We believe that cash on hand, cash from operations and borrowings expected to be available under our revolving credit facilities will provide sufficient funds to fund planned capital expenditures, make scheduled principal and interest payments, fund warranty payments, and meet other cash requirements. We currently expect to fund future capital expenditures from operations and financing activities. 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.

Capital Requirements. Our capital expenditure guidance for 2025 is $190 million to $210 million. In addition to the construction of the Arkansas facility, our capital allocation priorities for 2025 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.

As previously announced, the Company anticipates spending approximately $550 million on the Arkansas facility, of which we have already invested $484 million.

Inventory in Distribution Channels. We sell our 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.

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.

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

23

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 estimated future claims. We review and adjust these estimates, if necessary, based on the differences between actual experience and historical estimates. Additionally, we accrue for warranty costs associated with occasional or unanticipated product quality issues if a loss is probable and can be reasonably estimated.

We continue to receive and settle claims for decking products manufactured at our Nevada facility prior to 2007 that exhibit surface flaking and maintain a warranty reserve to provide for the settlement of these claims. Estimating the warranty reserve for surface flaking claims requires us to estimate the number of claims to be settled with payment and the average cost to settle each claim. We monitor surface flaking claims activity each quarter for indications that our estimates require revision.

Seasonality. The operating results for Trex have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions 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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For information regarding our exposure to certain market risks, see “Quantitative and Qualitative Disclosures about Market Risk,” in Part II, Item 7A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Item 4. Controls and Procedures

The Company’s management, with the participation of its President and Chief Executive Officer, who is the Company’s principal executive officer, and its Senior Vice President and Chief Financial Officer, who is the Company’s principal financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures as of June 30, 2025. Based on this evaluation, the President and Chief Executive Officer and the Senior Vice President and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective. There have been no changes in the Company’s internal control over financial reporting during the six-month period ended June 30, 2025, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
