On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Class A common stock, par value $0.001 per share, of the Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (other than any shares of Company Common Stock held by the Company as treasury stock, directly by James Hardie or Merger Sub or by any dissenting stockholder) will be canceled and converted into the right to receive $26.45 in cash, without interest, from James Hardie and 1.0340 ordinary shares of James Hardie, par value EUR 0.59 per share, (“James Hardie ordinary shares”), as well as cash in lieu of fractional shares. Upon completion of the transaction, former holders of Company Common Stock are expected to own approximately 26% of the combined company and the Company’s current credit facilities are expected to be paid off. See Note 8 for more information about the Company’s current credit facilities.

The boards of directors of the Company and James Hardie have each unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger. The transaction, which is currently expected to close in the second half of calendar year 2025, is subject to the approval of the Company’s stockholders, the required regulatory approval and other customary closing conditions.

In the three and six months ended March 31, 2025, the Company recognized $5.0 million in costs related to the proposed Merger with James Hardie in "Selling, general and administrative expenses" within the Condensed Consolidated Statements of Comprehensive Income (Loss).

b.Summary of Significant Accounting Policies

Basis of Presentation

The Company operates on a fiscal year ending September 30. The accompanying unaudited Condensed Consolidated Financial Statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, and in management’s opinion, includes all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, its results of operations and cash flows for the interim periods presented. The results of operations for the three and six months ended ~~December~~March 31, ~~2024~~2025 and the cash flows for the ~~three~~six months ended ~~December~~March 31, ~~2024~~2025 are not necessarily indicative of the results to be expected for the full fiscal year or any other period. The Company’s financial condition and 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, consumer spending and preferences, interest rates, the impact of any supply chain disruptions, economic conditions, and/or any adverse effects from geopolitical conflicts, global health pandemics and other factors beyond the Company’s control. Management cannot predict the degree to, or the period over, which the Company may be affected by such factors.

The accompanying unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 2024 (the “2024 Form 10-K”) filed with the Securities and Exchange Commission (the “SEC”) on November 20, 2024. The Condensed Consolidated Balance Sheet as of September 30, 2024 was derived from the audited financial statements at that date.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Significant estimates include revenue recognition, reserves for excess inventory, inventory obsolescence, inventory valuation, product warranties, customer rebates, stock-based compensation, litigation, income taxes, contingent consideration, goodwill and intangible asset valuation and accounting for long-lived assets. Management’s estimates and assumptions are evaluated on an ongoing basis and are based on historical experience, current conditions and available information. Actual results may differ from estimated amounts. Estimates are revised as additional information becomes available.

3. DIVESTITURE

On November 1, 2023, the Company completed the sale of its Vycom business within the Commercial segment for net proceeds of approximately $131.8 million.

The gain on sale of $37.7 million was recognized in "Gain on sale of business" within the Condensed Consolidated Statements of Comprehensive Income (Loss) for the year ended September 30, 2024. The Company did not report the sale in discontinued operations as it was not a strategic shift that would have a major effect on the Company's operations and financial results.

Previous Credit Facilities

The Term Loan Agreement was a first lien term loan entered into on April 28, 2022 by the Company's wholly-owned subsidiary, The AZEK Group LLC. On September 26, 2024, the obligations under the Term Loan Agreement were paid off in full and the Term Loan Agreement was terminated. On September 26, 2024, The AZEK Group LLC entered into a new $440.0 million first lien term loan facility (the "2024 Term Loan Facility"), the proceeds of which were applied, among other uses, to prepay the obligations of the Term Loan Agreement in full.

The AZEK Group LLC had also entered into a revolving credit facility, as amended and restated from time to time (the “Revolving Credit Facility”), with certain of the Company's direct and indirect subsidiaries and certain lenders party thereto. The Revolving Credit Facility provided for maximum aggregate borrowings of up to $150.0 million, subject to an asset-based borrowing base. The borrowing base was limited to a set percentage of eligible accounts receivable and inventory, less reserves that may be established by the administrative agent and the collateral agent in the exercise of their reasonable credit judgment. The AZEK Group LLC had the option to increase the commitments under the Revolving Credit Facility by up to $100.0 million, subject to certain conditions. On September 26, 2024, the Revolving Credit Facility was terminated. On September 26, 2024, the AZEK Group LLC entered into a new $375.0 million first lien revolving credit facility (the "2024 Revolving Credit Facility" and, together with the 2024 Term Loan Facility, the “Senior Secured Credit Facilities”).

11A “commitment fee” accrued on any unused portion of the commitments under the Revolving Credit Facility during the preceding three calendar month period. The commitment fees were $0.1 million and $0.3 million under the Revolving Credit Facility for the three and six months ended March 31, 2024, respectively .

Current Credit Facilities

On September 26, 2024, The AZEK Group LLC (the “Borrower”), entered into a senior credit agreement (the “Senior Secured Credit Agreement”), consisting of the Senior Secured Credit Facilities.

The 2024 Term Loan Facility will mature on September 26, 2031, subject to acceleration or prepayment. Commencing on March 31, 2025, the 2024 Term Loan Facility will amortize in equal quarterly installments of 0.25% of the aggregate principal amount of the loans outstanding, subject to reduction for certain prepayments. The 2024 Revolving Credit Facility will mature on September 26, 2029 and the 2024 Revolving Credit Facility will not amortize.

All obligations under the Senior Secured Credit Facilities are unconditionally guaranteed jointly and severally by (i) the Company, (ii) the Borrower and (iii) the wholly owned domestic subsidiaries of the Borrower (the “Guarantors”). All future wholly-owned domestic subsidiaries of the Borrower will be required to guarantee the Senior Secured Credit Facilities, except to the extent such subsidiary is an immaterial subsidiary or an excluded subsidiary. The Senior Secured Credit Facilities are secured by a first priority security interest in the membership interests of the Borrower and substantially all of the present and future assets of the Borrower and the Guarantors named therein, including equity interests of their domestic subsidiaries, subject to certain exceptions.

The interest rate applicable to loans under the 2024 Term Loan Facility equals (i) in the case of alternative base rate borrowings, the highest of (a) the Federal Funds Rate plus ½ of 1.00%, (b) the Prime Rate and (c) the one-month Term SOFR plus 1.00% per annum, provided that, in no event will the alternative base rate be less than 1.50% per annum, plus an applicable margin of 1.00% and (ii) in the case of SOFR borrowings, Term SOFR for the applicable interest period, provided that, in no event will Term SOFR be less than 0.50%, plus an applicable margin of 2.00%.

The interest rate applicable to loans under the 2024 Revolving Credit Facility equals (i) in the case of alternative base rate borrowings, the highest of (a) the Federal Funds Rate (as defined in the Senior Secured Credit Agreement) plus ½ of 1.00%, (b) the Prime Rate (as defined in the Senior Secured Credit Agreement) and (c) the one-month Term SOFR (as defined in the Senior Secured Credit Agreement) plus 1.00% per annum, provided that, in no event will the alternative base rate be less than 1.00% per annum, plus an applicable margin between 0.50% and 1.25%, depending on the Company's first lien net leverage ratio and (ii) in the case of SOFR borrowings, Term SOFR for the applicable interest period, provided that, in no event will Term SOFR be less than 0.00%, plus an applicable margin between 1.50% and 2.25%, depending on the first lien net leverage ratio.

The Senior Secured Credit Facilities may be voluntarily prepaid in whole, or in part, in each case without premium or penalty (other than, (i) any breakage costs in connection with voluntary prepayments of Term SOFR Loans, and (ii) the Prepayment Premium, if applicable), subject to certain customary conditions. The Senior Secured Credit Agreement also requires mandatory prepayments of loans under the Senior Secured Credit Facilities from the proceeds of certain debt issuances and certain asset dispositions (subject to certain reinvestment rights) and, commencing with the fiscal year ended September 30, 2025, a percentage of excess cash flow (subject to step-downs upon Borrower achieving certain leverage ratios and other reductions in connection with other debt prepayments). The Senior Secured Credit Agreement contains affirmative covenants, negative covenants and financial maintenance covenants that are customary for agreements of this type. The Senior Secured Credit Agreement includes customary events of default, including upon the occurrence of a change of control.

As of ~~December~~March 31, ~~2024~~2025 and September 30, 2024, The AZEK Group LLC had $438.9 million and $440.0 million outstanding under the 2024 Term Loan Facility.

10. LEASES

The Company leases vehicles, machinery, manufacturing facilities, office space, land, and equipment under both operating and finance leases. The Company determines if an arrangement is a lease at inception. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. As of December 31, 2024 and September 30, 2024, amounts associated with leases are included in Other assets, Accrued expenses and other liabilities and Other non-current liabilities in the Company’s Condensed Consolidated Balance Sheet.

For leases with initial terms greater than 12 months, the Company considers these right-of-use assets, or ROU assets, and records the related asset and obligation at the present value of lease payments over the term. For leases with initial terms equal to or less than 12 months, the Company does not consider them as ROU assets and instead considers them short-term lease costs that are recognized on a straight-line basis over the lease term. The Company’s leases may include escalation clauses, renewal options and/or termination options that are factored into the determination of lease term and lease payments when it is reasonably certain the option will be exercised. Renewal options range from 1 year to 20 years.

11. FAIR VALUE OF FINANCIAL INSTRUMENTS

FASB Accounting Standards Codification (“ASC”) requirements for Fair Value Measurements and Disclosures establish a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels. Level 1 inputs, the highest priority, are quoted prices in active markets for identical assets or liabilities. Level 2 inputs reflect other than quoted prices included in Level 1 that are either observable directly or through corroboration with observable market data. Level 3 inputs are unobservable inputs, due to little or no market activity for the asset or liability, such as internally-developed valuation models. The Company does not have any assets or liabilities measured at fair value on a recurring basis that are Level 3.

Derivative Instruments

The Company’s objective in using interest rate derivative instruments is to hedge against interest rate volatility associated with its Senior Secured Credit Facilities by converting a portion of its floating rate debt to fixed rate debt. In November 2022, the Company entered into two interest rate swap agreements with Barclays Bank PLC to manage interest rate risk related to Term Loan. Each agreement has a notional amount of $150 million and will expire on October 31, 2025. One agreement swaps variable interest at a rate based on SOFR with a fixed rate of 4.39% and the second with a fixed rate of 4.48%.

In connection with the 2024 Term Loan refinancing on September 26, 2024, the hedging relationship between the two interest rate swaps and the ~~2022~~ Term Loan Agreement was de-designated and the new hedging relationship between these interest rate swaps and the 2024 Term Loan Facility was simultaneously re-designated. All key terms of the interest rate swap agreements remain the same at re-designation. See Note 8 for additional information on the current credit facilities.

At the inceptions of the swap agreements and as of ~~December~~March 31, ~~2024~~2025, both swaps were designated and qualified as cash flow hedges in accordance with ASC 815. The gain (loss) is recorded in Accumulated other comprehensive income (loss) and then reclassified into Interest expense in the same period in which the hedged transaction affects earnings. As of ~~December~~March 31, ~~2024~~2025, the Company expects to reclass approximately $0.86 million ($0.64 million after-tax) as an increase to interest expense in the next 12 months.

The following table provides the fair values of the interest rate derivative instruments as well as their classifications on the Balance Sheet as of ~~December~~March 31, ~~2024~~2025 and September 30, 2024 (in thousands):

12. SEGMENTS

Operating segments for the Company are determined based on information used by the chief operating decision maker (“CODM”) in deciding how to evaluate performance and allocate resources to each of the segments. The CODM reviews Adjusted EBITDA and Adjusted EBITDA Margin as the key segment measures of performance. Adjusted EBITDA is defined as ~~segment~~net ~~operating~~ income (loss) ~~plus~~before interest expense, net, income tax (benefit) expense and depreciation and amortization, adjusted by adding thereto or subtracting therefrom stock-based compensation costs, acquisition and divestiture costs, and certain other items of expense and income. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by net sales. Residential Segment Adjusted EBITDA includes all corporate expenses, such as selling, general and administrative costs related to our corporate offices, including payroll and other professional fees.

The Company has two reportable segments, Residential and Commercial. The reportable segments were determined primarily based on products and end markets as follows:

•Residential—The Residential segment manufactures and distributes decking, rail, trim, moulding, pergolas and cabanas and accessories through a national network of dealers and distributors and multiple home improvement retailers providing ~~extensive geographic coverage and enabling the Company to effectively serve contractors. This segment is impacted by trends in and the strength of home repair and remodel activity.~~

•Commercial—The Commercial segment manufactures, fabricates and distributes lockers and bathroom partitions. This segment is impacted by trends in and the strength of the repair and remodel sector and the new construction sector. This segment also previously included the Company’s Vycom business, which manufactured resin-based extruded sheeting products for a variety of commercial and industrial applications. The Company sold the Vycom business on November 1, 2023. See Note 3 for additional information on the divestiture.

Share Repurchase Program

On May 5, 2022, the Board of Directors authorized the Company to repurchase up to $400 million of the Company’s Class A common stock (the “2022 Share Repurchase Authorization”). On June 12, 2024, the Board of Directors authorized the Company to repurchase up to $600 million of the Company’s Class A common stock (together with the 2022 Share Repurchase Authorization, the “Share Repurchase Program”) in addition to the then remaining approximately $76 million available pursuant to the 2022 Share Repurchase Authorization. The Share Repurchase Program allows the Company to repurchase its shares opportunistically from time to time. Purchases may be effected through one or more open market transactions, privately negotiated transactions, transactions structured through investment banking institutions, accelerated share repurchases or tender offers, some of which may be effected through Rule 10b5-1 plans, or a combination of the foregoing. The timing of repurchases will depend upon several factors, including market and business conditions, and repurchases may be discontinued at any time.

14. STOCK-BASED COMPENSATION

The Company grants stock-based awards to attract, retain and motivate key employees and directors.

The 2020 Omnibus Incentive Compensation Plan (“2020 Plan”), provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent rights, and performance-based or other equity-related awards to the Company’s employees and directors. The maximum aggregate number of shares that may be issued under the 2020 Plan is 15,852,319 shares with 12,~~951~~131,~~786~~170 shares remaining in the reserve. The total aggregate number of shares may be adjusted as determined by the Board of Directors.

17On December 11, 2023, the Compensation Committee of the Board of Directors authorized certain changes to a former employee’s stock-based awards which were effective in connection with his retirement. These changes allow certain awards to continue to vest in due course following retirement and extend the exercisability of certain outstanding and exercisable stock options to the end of the contractual term of the options. This resulted in a Type III Modification (improbable to probable) as defined in accounting guidance, accounted for as a cancellation of the original award and an issuance of a new grant, as well as, a Type I Modification (probable to probable), accounted for as an exchange of the original award for a new grant under the revised terms. The modifications resulted in $1.9 million of stock-based compensation expense in the six months ended March 31, 2024.

Stock-based compensation expense for the three months ended March 31, 2025 and 2024 was $4.7 million and $6.3 million, respectively, and for the six months ended March 31, 2025 and 2024 was $9.6 million and $14.8 million, respectively, recognized in “Selling, general and administrative expenses” in the Condensed Consolidated Statements of Comprehensive Income (Loss). Total income tax benefit for the three months ended March 31, 2025 and 2024 was $1.2 million and $1.3 million, respectively, and for the

Performance Restricted Stock Units

Performance restricted stock units were granted to officers and certain employees of the Company and represent the right to earn shares of Company common stock based on the achievement of company-wide financial performance targets, including net sales, return on net tangible assets, adjusted return on invested capital, and Adjusted EBITDA during the ~~three-year~~ performance period. Compensation cost is amortized into expense over the performance period, which is generally three years, and is based on the probability of meeting performance targets. The fair value of each performance share award is based on the closing stock price on the date of grant.

15. EARNINGS PER SHARE

The Company computes earnings per common share (“EPS”) under the two-class method which requires the allocation of all distributed and undistributed earnings attributable to the Company to common stock and other participating securities based on their respective rights to receive distributions of earnings or losses. The Company’s Class A common stock and Class B common stock equally share in distributed and undistributed earnings, and, therefore, no allocation to participating securities or dilutive securities is performed.

Basic EPS attributable to common stockholders is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding. Diluted EPS is calculated by adjusting weighted average shares outstanding for the dilutive effect of potential common shares, determined using the treasury-stock method. For purposes of the diluted EPS calculation, restricted stock awards, restricted stock units and options to purchase shares of common stock are considered to be potential common shares. The following table sets forth the computation of the Company’s basic and diluted EPS attributable to common stockholders (in thousands, except share and per share amounts):

16. INCOME TAXES

The Company calculates the interim tax provision in accordance with the provisions of ASC 740-270, Income Taxes; Interim Reporting, specifically ASC-740-270-25-2. For interim periods, the Company estimates the annual effective income tax rate and applies the estimated rate to the year-to-date income or loss before income taxes. The effective income tax rates for the three months ended ~~December~~March 31, ~~2024~~2025 and ~~2023~~2024 were 724.6% and 23.5%, respectively, and 39for the six months ended March 31, 2025 and 2024 were 21.0% and 29.9%, respectively. The ~~decrease~~increase in the effective income tax rate for the three months ended ~~December~~March 31, ~~2024~~2025, as compared to the three months ended ~~December~~March 31, ~~2023~~2024, was primarily driven by lower tax benefits related to stock-based compensation and higher taxable income. The decrease in the effective income tax rate for the six months ended March 31, 2025, as compared to the six months ended March 31, 2024, was primarily driven by tax benefits related to stock-based compensation and the removal of the tax effects related to the sale of the Vycom business.

17. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

In the normal course of the Company’s business, it is at times subject to various other legal actions, in some cases for which the relief or damages sought may be substantial. Although the Company is not able to predict the outcome of legal actions to which it may be subject, after reviewing all pending and threatened actions with counsel and based on information currently available, management believes that the outcome of such actions, individually or in the aggregate, will not have a material adverse effect on the Company’s results of operations or financial position. However, it is possible that the ultimate resolution of such matters, if unfavorable, may be material to the Company’s results of operations in a particular future period as the time and amount of any resolution of such actions and its relationship to the future results of operations are not currently known. The Company accrues for losses when they are probable of occurrence and such losses are reasonably estimable. Legal costs expected to be incurred are accounted for as they are incurred.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our annual consolidated financial statements and related notes and our discussion and analysis of financial condition and results of operations, which were included in our 2024 Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission, or the SEC, on November 20, 2024, or our 2024 Form 10-K, as well as Item 1. Financial Statements in this Form 10-Q.

These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in the section titled “Risk Factors” set forth in Part I, Item 1A of our 2024 Form 10-K. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this Quarterly Report on Form 10-Q may not occur and actual results may differ materially and adversely from those anticipated or implied in the forward-looking statements. You should read this Quarterly Report on Form 10-Q with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect. In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Quarterly Report on Form 10-Q. While we believe that such information provides a reasonable basis for these statements, such information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

Overview

We are an industry-leading designer and manufacturer of beautiful, low-maintenance and environmentally sustainable outdoor living products, including TimberTech® decking and railing, Versatex® and AZEK® Trim, and StruXure® pergolas. Homeowners continue to invest in their homes and outdoor spaces and increasingly recognize the significant advantages of engineered, long-lasting products, which convert demand away from traditional materials, particularly wood. Our products transform those outdoor spaces by combining beautiful aesthetics with lower maintenance as compared to traditional materials. Our innovative range of outdoor living and home exterior products, including decking, railing, exterior trim, siding, cladding, pergolas and cabanas and accessories, inspires consumers to design outdoor spaces tailored to their unique lifestyle needs. In addition to our leading suite of outdoor living products, we sell a broad range of highly engineered products that are sold in commercial markets, including partitions, lockers and storage solutions. One of our core values is to “always do the right thing”. In furtherance of that value, we are focused on sustainability across our operations and have adopted strategies to enable us to meet the growing demand for environmentally-friendly products.

We report our results in two segments: Residential and Commercial. In our Residential segment, our primary consumer brands, TimberTech and AZEK, are recognized by contractors and consumers for their premium aesthetics, uncompromising quality and performance, and diversity of style and design options. Our Commercial segment manufactures high-quality bathroom partitions and lockers and, prior to our divestiture of the Vycom business on November 1, 2023, also manufactured engineered sheet products. Over our history we have developed a reputation as a leading innovator in our markets by leveraging our differentiated manufacturing capabilities, material science expertise and product management proficiency to consistently introduce new products into the market. This long-standing commitment has enabled us to stay at the forefront of evolving industry trends and consumer demands, which in turn has allowed us to become a leader across our core product categories.

Proposed Merger with James Hardie Industries plc

On March 23, 2025, we entered into an Agreement and Plan of Merger, or the Merger Agreement, with James Hardie Industries plc, an Irish public limited company, or James Hardie, and Juno Merger Sub Inc., a Delaware corporation and an indirect wholly owned subsidiary of James Hardie, or Merger Sub. The Merger Agreement provides that, among other things and on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into us with us surviving the merger, or the Merger, as an indirect wholly owned subsidiary of James Hardie. Our board of directors and the board of directors of James Hardie have each unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger.

On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger, or the Effective Time, each share of our Class A common stock, par value $0.001 per share, or Company Common Stock, issued and outstanding immediately prior to the Effective Time (other than any shares of Company Common Stock held by us as treasury stock, directly by James Hardie or Merger Sub or by any dissenting stockholder) will be canceled and converted into the right to receive $26.45 in cash, without interest, from James Hardie and 1.0340 James Hardie ordinary shares, as well as cash in lieu of fractional shares. Upon completion of the transaction, former holders of Company Common Stock are expected to own approximately 26% of the combined company and our current credit facilities are expected to be paid off. See Note 8 to our Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for more information about our current credit facilities..

The transaction, which is currently expected to close in the second half of calendar year 2025, is subject to the approval of our stockholders, the required regulatory approval and other customary closing conditions.

In the three and six months ended March 31, 2025, we recognized $5.0 million in costs related to the proposed Merger with James Hardie in "Selling, general and administrative expenses" within the Condensed Consolidated Statements of Comprehensive Income (Loss).

Recent Divestiture

On November 1, 2023, we completed the sale of the Vycom business within the Commercial segment for net proceeds of approximately $131.8 million. The divestiture allowed us to focus on the highest value portions of our business and provided additional cash to finance our capital allocation priorities. As a result of the divestiture, we recognized a pre-tax gain on sale of $37.7 million during the year ended September 30, 2024.

Segment Results of Operations

We report our results in two segments: Residential and Commercial. The key segment measures used by our chief operating decision maker in deciding how to evaluate performance and allocate resources to each of the segments are Segment Adjusted EBITDA and Segment Adjusted EBITDA Margin. Depending on certain circumstances, Segment Adjusted EBITDA and Segment Adjusted EBITDA Margin may be calculated differently, from time to time, than our Adjusted EBITDA and Adjusted EBITDA Margin, which are further discussed under the heading “Non-GAAP Financial Measures.” Segment Adjusted EBITDA and Segment Adjusted EBITDA Margin represent measures of segment profit reported to our chief operating decision maker for the purpose of making decisions about allocating resources to a segment and assessing its performance and are determined as disclosed in our Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q consistent with the requirements of the Financial Accounting Standards Board’s, or FASB, Accounting Standards Codification, or ASC 280, Segment Reporting. We define Segment Adjusted EBITDA as a segment’s net income (loss) before income tax (benefit) expense and by adding to or subtracting therefrom interest expense, net, depreciation and amortization, share-based compensation costs, asset impairment and inventory revaluation costs, business transformation costs, capital structure transaction costs, acquisition costs, initial public offering costs and certain other costs. Segment Adjusted EBITDA Margin is equal to a segment’s Segment Adjusted EBITDA divided by such segment’s net sales. Residential Segment Adjusted EBITDA includes all corporate expenses, such as selling, general and administrative costs related to our corporate offices, including payroll and other professional fees.

Net sales for the three months ended ~~December~~March 31, ~~2024~~2025 decreased by $4.0.7 million, or 234.03%, to $1315.42 million from $1715.49 million for the three months ended ~~December~~March 31, ~~2023~~2024, primarily due to ~~the sale of the Vycom business and~~ weaker demand in our Scranton Products business. ~~Vycom net sales were $3.3 million for the three months ended December 31, 2023 (prior to its divestment on November 1, 2023).~~

Net sales for the six months ended March 31, 2025 decreased by $4.7 million, or 14.1%, to $28.6 million from $33.3 million for the six months ended March 31, 2024, primarily due to the sale of the Vycom business and weaker demand in our Scranton Products business. Vycom net sales were $3.3 million for the six months ended March 31, 2024 (prior to its divestment on November 1, 2023).

Segment Adjusted EBITDA

Segment Adjusted EBITDA of the Commercial segment was $1.59 million for the three months ended ~~December~~March 31, ~~2024~~2025, compared to $2.9 million for the three months ended ~~December~~March 31, ~~2023~~2024. The decrease was primarily driven by lower net sales due to ~~the sale of the Vycom business,~~ weaker demand and higher purchased material costs.

Segment Adjusted EBITDA of the Commercial segment was $3.4 million for the six months ended March 31, 2025, compared to $5.8 million for the six months ended March 31, 2024. The decrease was primarily driven by lower net sales due to the sale of the Vycom business, weaker demand and higher purchased material costs.

Non-GAAP Financial Measures

To supplement our Condensed Consolidated Financial Statements prepared and presented in accordance with generally accepted accounting principles in the United States, or GAAP, we use certain non-GAAP performance financial measures, as described below, to provide investors with additional useful information about our financial performance, to enhance the overall understanding of our past performance and future prospects and to allow for greater transparency with respect to important metrics used by our management for financial and operational decision-making. We are presenting these non-GAAP financial measures to assist investors in seeing our financial performance from management’s view and because we believe they provide an additional tool for investors to use in comparing our core financial performance over multiple periods with other companies in our industry. Our GAAP financial results include significant expenses that may not be indicative of our ongoing operations as detailed in the tables below.

However, non-GAAP financial measures have limitations in their usefulness to investors because they have no standardized meaning prescribed by GAAP and are not prepared under any comprehensive set of accounting rules or principles. In addition, non-GAAP financial measures may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies. As a result, non-GAAP financial measures should be viewed as supplementing, and not as an alternative or substitute for, our Condensed Consolidated Financial Statements prepared and presented in accordance with GAAP.

Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA, Adjusted EBITDA Margin and Free Cash Flow

We define Adjusted Gross Profit as gross profit before amortization, acquisition costs and certain other costs. Adjusted Gross Profit Margin is equal to Adjusted Gross Profit divided by net sales. We define Adjusted Net Income as net income (loss) before amortization, stock-based compensation costs, acquisition and divestiture costs, initial public offering and secondary offering costs, capital structure transaction costs and certain other items of expense and income as described below. We define Adjusted Diluted EPS as Adjusted Net Income divided by weighted average common shares outstanding—diluted, to reflect the conversion or exercise, as applicable, of all outstanding shares of restricted stock awards, restricted stock units and options to purchase shares of our common stock. We define Adjusted EBITDA as net income (loss) before interest expense, net, income tax (benefit) expense and depreciation and amortization and by adding to or subtracting therefrom items of expense and income as described below. Adjusted EBITDA Margin is equal to Adjusted EBITDA divided by net sales. We believe Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin are useful to investors because they help identify underlying trends in our business that could otherwise be masked by certain expenses that can vary from company to company depending on, among other things, its financing, capital structure and the method by which its assets were acquired, and can also vary significantly from period to period. For example, we add back amortization and certain stock-based compensation costs when calculating Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income and Adjusted Diluted EPS because we do not consider them indicative of our core operating performance. We believe their exclusion, and the exclusion of certain other expenses as described herein, facilitates comparisons of our operating performance on a period-to-period basis. Therefore, we believe that showing gross profit and net income, as adjusted to remove the impact of these expenses, is helpful to investors in assessing our gross profit and net income performance in a way that is similar to the way management assesses our performance. Additionally, EBITDA and EBITDA margin are common measures of operating performance in our industry, and we believe they facilitate operating comparisons. Our management also uses Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted EBITDA and Adjusted EBITDA Margin in conjunction with other GAAP financial measures for planning purposes, including as a measure of our core operating results and the effectiveness of our business strategy, and in evaluating our financial performance.

Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin have limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

•These measures do not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments;

•These measures do not reflect changes in, or cash requirements for, our working capital needs;

Table of contents

•Adjusted EBITDA and Adjusted EBITDA Margin do not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debt;

•Adjusted EBITDA and Adjusted EBITDA Margin do not reflect our income tax expense or the cash requirements to pay our taxes;

•Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin exclude the expense of amortization of our assets, and Adjusted EBITDA and Adjusted EBITDA Margin also exclude the expense of depreciation of our assets, and, although these are non-cash expenses, the assets being depreciated or amortized may have to be replaced in the future;

•Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin exclude the expense associated with our equity compensation plan, although equity compensation has been, and will continue to be, an important part of our compensation strategy;

Table of contents

•Adjusted Gross Profit, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin exclude acquisition costs and other costs, each of which can affect our current and future cash requirements; and

•Other companies in our industry may calculate Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin differently than we do, limiting their usefulness as comparative measures.

Because of these limitations, none of these metrics should be considered indicative of discretionary cash available to us to invest in the growth of our business or as measures of cash that will be available to us to meet our obligations.

In addition, we provide Free Cash Flow, which is a non-GAAP financial measure that we define as net cash provided by (used in) operating activities less purchases of property, plant and equipment. We believe Free Cash Flow is useful to investors as an important liquidity measure of the cash that is available to us after capital expenditures. Free Cash Flow is used by our management as a measure of our ability to generate and use cash, including in order to invest in future growth, fund acquisitions, return capital to our stockholders and repay indebtedness. Our use of Free Cash Flow has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results under GAAP. Some of these limitations are:

•Free Cash Flow is not a substitute for net cash provided by (used in) operating activities, including because our capital expenditures as a manufacturing company can be significant and can vary from period to period;

•Free Cash Flow does not reflect our future contractual commitments or mandatory debt repayments and accordingly does not represent residual cash flow available for discretionary expenditures or the total increase or decrease in our cash balance for a given period; and

•Other companies in our industry may calculate Free Cash Flow differently than we do, limiting its usefulness as a comparative measure.

The following table presents reconciliations of the most comparable financial measures calculated in accordance with GAAP to these non-GAAP financial measures for the periods indicated:

Liquidity and Capital Resources

Liquidity Outlook

Our primary cash needs are to fund operations, working capital, capital expenditures, debt service, share repurchases and any acquisitions we may undertake. As of ~~December~~March 31, ~~2024~~2025, we had cash and cash equivalents of $~~148~~146.17 million and total indebtedness of $438.9 million. The AZEK Group LLC (f/k/a CPG International LLC), our direct, wholly owned subsidiary, had approximately $372.7 million available under our 2024 Revolving Credit Facility for future borrowings as of ~~December~~March 31, ~~2024~~2025.

We believe we will have adequate liquidity over the next 12 months to operate our business and to meet our cash requirements as a result of cash flows from operating activities, available cash balances and availability under our 2024 Revolving Credit Facility after consideration of our debt service and other cash requirements. In the longer term, our liquidity will depend on many factors, including our results of operations, our future growth, the timing and extent of our expenditures to develop new products and improve our manufacturing capabilities, the expansion of our sales and marketing activities and the extent to which we make acquisitions. Changes in our operating plans, material changes in anticipated sales, increased expenses, acquisitions or other events may cause us to seek additional equity and/or debt financing in future periods.

Holding Company Status

We are a holding company and do not conduct any business operations of our own. As a result, we are largely dependent upon cash dividends and distributions and other transfers from our subsidiaries to meet our obligations. The agreements governing the indebtedness of our subsidiaries impose restrictions on our subsidiaries’ ability to pay dividends or make other distributions to us.

The AZEK Group LLC is party to the ~~Revolving Credit Facility and the Term Loan Agreement, or, together, the~~ Senior Secured Credit Facilities. The obligations under the Senior Secured Credit Facilities are secured by ~~specified~~substantially all of our assets, subject to certain exceptions set forth in the Senior Secured Credit Agreement. The obligations under the Senior Secured Credit Facilities are guaranteed by usThe AZEK Company Inc. and the wholly owned domestic subsidiaries of The AZEK Group LLC other than certain immaterial subsidiaries and other excluded subsidiaries.

The Senior Secured Credit Facilities contain covenants restricting payments of dividends by The AZEK Group LLC unless certain conditions, as provided in the Senior Secured Credit Facilities, are met. The covenants under our Senior Secured Credit Facilities provide for certain exceptions for specific types of payments. However, other than restricted payments under the specified exceptions, the covenants under our 2024 Term Loan ~~Agreement~~Facility generally prohibit the payment of dividends unless the Total Net Leverage Ratio (as defined in the 2024 Term Loan ~~Agreement~~Facility) of The AZEK Group LLC, on a pro forma basis, is no greater than 43.2575:1.00 and no event of default has occurred and is occurring.

Since our and our subsidiaries’ restricted net assets exceed 25% of our consolidated net assets, in accordance with Rule 12-04, Schedule 1 of Regulation S-X, refer to our Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for condensed parent company financial statements of the Company.

Cash Sources

We have historically relied on cash flows from operations generated by The AZEK Group LLC, borrowings under the credit facilities, issuances of notes and other forms of debt financing and capital contributions to fund our cash needs.

On September 26, 2024, our subsidiary, The AZEK Group LLC, Wells Fargo Bank, National Association, as administrative agent and collateral agent, or the Revolver Administrative Agent, and the lenders party thereto entered into the 2024 Revolving Credit Facility. The 2024 Revolving Credit Facility provides for maximum aggregate borrowings of up to $375.0 million, subject to our Total Net Leverage Ratio remaining below 4.00:1.00 and our Interest Coverage Ratio (as defined in the Senior Secured Credit Agreement) remaining above 3.00:1.00. As of December 31, 2024 and September 30, 2024, The AZEK Group LLC had no outstanding borrowings under the Revolving Credit Facility and had $2.3 million and $2.2 million of outstanding letters of credit held against the Revolving Credit Facility, respectively. As of December 31, 2024 and September 30, 2024, The AZEK Group LLC had approximately $372.7 million and $372.8 million available under the borrowing base for future borrowings in addition to cash and cash equivalents on hand of $148.1 million and $164.0 million, respectively.34

Cash Uses

Our principal cash requirements have included working capital, capital expenditures, payments of principal and interest on our debt, share repurchases, and, if market conditions warrant, making selected acquisitions. We may elect to use cash from operations, debt proceeds, equity or a combination thereof to finance future acquisition opportunities.

Net cash provided by financing activities for the ~~three~~six months ended ~~December~~March 31, ~~2024~~2025 primarily consisted of $19.6 million received from the exercise of vested stock options, partially offset by $(1.1) million of debt principal payments, $(13.94) million of excise tax payments for share repurchase, and $(45.94) million of cash paid for shares withheld for taxes, ~~partially offset by $11.7 million of exercise of vested stock options,~~ while net cash used in financing activities for the ~~three~~six months ended ~~December~~March 31, ~~2023~~2024 primarily consisted of $(~~100~~125.0) million of treasury stock repurchases and $(13.50) million of debt principal payments, partially offset by $18.6 million of exercise of vested stock options.

Share Repurchase Program

On May 5, 2022, the Board of Directors authorized us to repurchase up to $400 million of our Class A common stock. On June 12, 2024, the Board of Directors authorized us to repurchase up to $600 million of our Class A common stock in addition to the then remaining approximately $76 million available pursuant to our prior authorization. The program allows us to repurchase our shares opportunistically from time to time. Purchases may be effected through one or more open market transactions, privately negotiated transactions, transactions structured through investment banking institutions, accelerated share repurchases or tender offers, some of which may be effected through Rule 10b5-1 plans, or a combination of the foregoing. The timing of repurchases will depend upon several factors, including market and business conditions, and repurchases may be discontinued at any time.

See Note 13 in the Notes to Condensed Consolidated Financial Statements for additional information.

Availability under our Senior Secured Credit Facilities

On September 26, 2024, The AZEK Group LLC entered into the Senior Secured Credit Agreement, a new $815.0 million senior credit agreement, consisting of the $440.0 million 2024 Term Loan Facility and the $375.0 million 2024 Revolving Credit Facility.

The 2024 Term Loan Facility will mature on September 26, 2031, subject to acceleration or prepayment. Commencing on March 31, 2025, the 2024 Term Loan Facility will amortize in equal quarterly installments of 0.25% of the aggregate principal amount of the loans outstanding, subject to reduction for certain prepayments. The 2024 Revolving Credit Facility will mature on September 26, 2029, and the 2024 Revolving Credit Facility will not amortize.

All obligations under the Senior Secured Credit Facilities are unconditionally guaranteed jointly and severally by (i) The AZEK Company Inc., (ii) The AZEK Group LLC, or the Borrower, and (iii) the wholly owned domestic subsidiaries of the Borrower, or the Guarantors. All future wholly-owned domestic subsidiaries of the Borrower will be required to guarantee the Senior Secured Credit Facilities, except to the extent such subsidiary is an immaterial subsidiary or an excluded subsidiary. The Senior Secured Credit Facilities are secured by a first priority security interest in the membership interests of the Borrower and substantially all of the present and future assets of the Borrower and the Guarantors named therein, including equity interests of their domestic subsidiaries, subject to certain exceptions.

The interest rate applicable to loans under the 2024 Term Loan Facility equals (i) in the case of alternative base rate borrowings, the highest of (a) the Federal Funds Rate (as defined in the Senior Secured Credit Agreement) plus ½ of 1.00%, (b) the Prime Rate (as defined in the Senior Secured Credit Agreement) and (c) the one-month Term SOFR (as defined in the Senior Secured Credit Agreement) plus 1.00% per annum, provided that, in no event will the alternative base rate be less than 1.50% per annum, plus an applicable margin of 1.00% and (ii) in the case of SOFR borrowings, Term SOFR for the applicable interest period, provided that, in no event will Term SOFR be less than 0.50%, plus an applicable margin of 2.00%.

The interest rate applicable to loans under the 2024 Revolving Credit Facility equals (i) in the case of alternative base rate borrowings, the highest of (a) the Federal Funds Rate plus ½ of 1.00%, (b) the Prime Rate and (c) the one-month Term SOFR plus 1.00% per annum, provided that, in no event will the alternative base rate be less than 1.00% per annum, plus an applicable margin between 0.50% and 1.25%, depending on our first lien net leverage ratio and (ii) in the case of SOFR borrowings, Term SOFR for the ~~applicable interest period, provided that, in no event will Term SOFR be less than 0.00%, plus an applicable margin between 1.50% and 2.25%, depending on the first lien net leverage ratio.~~

applicable interest period, provided that, in no event will Term SOFR be less than 0.00%, plus an applicable margin between 1.50% and 2.25%, depending on the first lien net leverage ratio.

The Senior Secured Credit Facilities may be voluntarily prepaid in whole, or in part, in each case without premium or penalty (other than, (i) any breakage costs in connection with voluntary prepayments of Term SOFR Loans, and (ii) the Prepayment Premium, if applicable), subject to certain customary conditions. The Senior Secured Credit Facilities also require mandatory prepayments of loans under the Senior Secured Credit Facilities from the proceeds of certain debt issuances and certain asset dispositions (subject to certain reinvestment rights) and, commencing with the fiscal year ended September 30, 2025, a percentage of excess cash flow (subject to step-downs upon the Borrower achieving certain leverage ratios and other reductions in connection with other debt prepayments). The Senior Secured Credit Agreement contains affirmative covenants, negative covenants and financial maintenance covenants that are customary for facilities of this type. The Senior Secured Credit Facilities include customary events of default, including upon the occurrence of a change of control.

The Borrower has the right to arrange for incremental term loans and revolving loan commitments, either through an incremental amendment to the Senior Secured Credit Agreement or through the incurrence of incremental equivalent debt, in each case, in an amount that shall not exceed the sum of (i) the Fixed Incremental Amount, as defined in the Senior Secured Credit Agreement, and (ii) the Ratio Incremental Amount, as defined in the Senior Secured Credit Agreement.

Table of contents

Restrictions on Dividends

The Senior Secured Credit Facilities each restrict payments of dividends unless certain conditions, as provided in the Senior Secured Credit Agreement are met.

Contingent Commitments

We have contractual commitments for purchases of certain minimum quantities of raw materials at index-based prices, and non-cancelable capital and operating leases, outstanding letters of credit and fixed asset purchase commitments. For a description of our contractual obligations and commitments, see Notes 8 “Debt”, 10 “Leases” and 17 “Commitments and Contingencies” to our Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.

Critical Accounting Policies and Estimates

Our unaudited Condensed Consolidated Financial Statements are prepared in accordance with U.S. GAAP. The preparation of these unaudited Condensed Consolidated Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ materially from those estimates.

There have been no material changes to our critical accounting policies as compared to the critical accounting policies and significant judgments and estimates disclosed in our 2024 Form 10-K, except as updated in Note 1 of our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Recently Issued Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard requires all public entities that are subject to segment reporting requirements to disclose additional information, including significant segment expenses and other segment items on an annual and interim basis. It also requires the disclosure of the title and the position of the chief operating decision maker and how the reported measures are used for making business decisions. This standard is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We intend to adopt the updated standard for the annual reporting period beginning October 1, 2024. We do not expect the adoption of this standard will have a material impact on our disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This standard expands the disclosure requirements primarily on the rate reconciliation and income tax paid. For public entities, this standard is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. We intend to adopt the updated standard for the annual reporting period beginning October 1, 2025. We do not expect the adoption of this standard will have a material impact on our disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard requires all public companies to disclose more detailed information about certain costs and expenses in the notes to the financial statements at interim and annual reporting periods. This standard is effective for annual reporting periods beginning after December 15, 2026, with early adoption permitted. We intend to adopt the updated standard for the annual reporting period beginning October 1, 2027. We are currently evaluating the impact the adoption of this standard will have on our disclosures.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We are subject to interest rate risk in connection with our long-term debt. Our principal interest rate risk relates to the Senior Secured Credit Facilities. To meet our seasonal working capital needs, we borrow periodically on our variable rate revolving line of credit under the 2024 Revolving Credit Facility. As of ~~December~~March 31, ~~2024~~2025 and September 30, 2024, we had $438.9 million and $440.0 million outstanding under the 2024 Term Loan ~~Agreement~~Facility, respectively, and no outstanding amounts under the 2024 Revolving Credit Facility, respectively. The 2024 Term Loan ~~Agreement~~Facility and 2024 Revolving Credit Facility bear interest at variable rates. An increase or decrease of 100 basis points in the floating rates on the amounts outstanding under the Senior Secured Credit Facilities, after giving effect to related derivatives, as of ~~December~~March 31, ~~2024~~2025 and ~~2023~~2024, would have increased or decreased annual cash interest by approximately $1.4 million and $2.9 million, respectively.

We have entered into and may continue to enter into, agreements such as floating for fixed-rate interest rate swaps and other hedging contracts in order to hedge against interest rate volatility associated with our Senior Secured Credit Facilities. For example, effective November 2022, we entered into interest rate swaps, which swapped interest at a rate based on SOFR on a notional amount of $300 million for a fixed rate. We do not intend or expect to enter into interest rate swaps or other derivative transactions for speculative purposes. In the future, in order to manage our interest rate risk, we may refinance our existing debt.

Credit Risk

As of ~~December~~March 31, ~~2024~~2025 and September 30, 2024, our cash and cash equivalents were maintained at major financial institutions in the United States, and our current deposits are likely in excess of insured limits. We believe these institutions have sufficient assets and liquidity to conduct their operations in the ordinary course of business with little or no credit risk to us.

Foreign Currency Risk

Substantially all of our business is currently conducted in U.S. dollars. We do not believe that an immediate 10% increase or decrease in the relative value of the U.S. dollar as compared to other currencies would have a material effect on our operating results.

Inflation

Our cost of sales is subject to inflationary pressures and price fluctuations of the raw materials we use and other costs, including freight and labor costs. ~~Geopolitical~~Tariffs, geopolitical tensions and other economic uncertainties may increase inflationary pressures, including causing increases in the prices for goods and services and exacerbating global supply chain disruptions, which have resulted in, and may continue to result in, shortages in materials and services and related issues. Historically, we have generally been able over time to offset, in whole or in part, the effects of inflation and price fluctuations through sales price increases and production efficiencies associated with technological enhancements and volume growth; however, we cannot reasonably estimate our ability to offset any increases in raw material prices or freight or labor costs or other inflationary pressures in the future. Sustained or increased inflationary pressures may have an adverse effect on our business, financial condition and results of operations if the selling prices of our products do not increase with these increased costs or we cannot identify cost efficiencies.

Raw Materials

We rely upon the supply of certain raw materials in our production processes; however, we do not typically enter into fixed price contracts with our suppliers and currently have no fixed price contracts with our major vendors. The primary raw materials we use in the manufacture of our products are various petrochemical resins, including polyethylene, polypropylene and PVC resins, reclaimed polyethylene and PVC material, waste wood fiber and aluminum. In addition, we utilize a variety of other additives including modifiers, TiO2 and pigments. The exposures associated with these costs are primarily managed through terms of the sales and by maintaining relationships with multiple vendors. Prices for spot market purchases are negotiated on a continuous basis in line with the market at the time. We have not entered into hedges with respect to our raw material costs at this time, but we may choose to enter into such hedges in the future. Other than short term supply contracts for resins with indexed based pricing and occasional strategic purchases of larger quantities of certain raw materials, we generally buy materials on an as-needed basis.

The cost of some of the raw materials we use in the manufacture of our products is subject to significant price volatility. For example, the cost of petrochemical resins used in our manufacturing processes has historically varied significantly and has been affected by changes in supply and demand, including resulting from factors such as tariffs, inflation and interest rate changes, and in the price of crude oil. Substantially all of our resins are purchased under supply contracts that average approximately one to two years, for which pricing is variable based on an industry benchmark price index. The resin supply contracts are negotiated annually and generally provide that we are obligated to purchase a minimum amount of resins from each supplier. In addition, the price of reclaimed polyethylene material, waste wood fiber, aluminum, other additives (including modifiers, TiO2 and pigments) and other raw materials fluctuates depending on, among other things, overall market supply and demand and general business conditions.

Based on such evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were ~~not~~ effective asat ~~of December 31, 2024 because of~~ the ~~material~~reasonable ~~weaknesses~~assurance inlevel ~~our~~as ~~internal~~of ~~control over financial reporting described in Part II~~March 31, ~~Item 9A of our 2024 Form 10-K~~2025.

During the second quarter of 2025, we completed our testing of the operating effectiveness of these controls, determined the re-designed and enhanced controls were operating effectively as of March 31, 2025 and concluded that the previously identified material weaknesses have been remediated.

We took the following steps to address the root cause of the material weaknesses described above:

•With the assistance from our external consultant, we have evaluated, redesigned and implemented certain internal controls impacted by the material weaknesses.

•We have enhanced controls, both within our information technology environment and business process controls, to establish and maintain appropriate segregation of duties.

•We have provided training over the execution and review of manual journal entry controls to all applicable employees of the Company.

•In addition to our in-house training, we hired an external consultant to provide additional training to all applicable employees regarding prompt internal reporting of identified issues and concerns.

•We have provided technical accounting training to individuals involved in the process to reconcile inventory on a monthly basis.

•We have enhanced the design of the inventory reconciliation controls to standardize the review to improve the reliability of information used by accounting personnel.

•We have enhanced our monitoring level controls to detect material and unusual variances in inventory account balances and cost of sales activity.

While we believe these efforts will improve our internal controls and address the root cause of the material weaknesses, such material weaknesses will not be remediated until we have concluded, through testing, that our controls are operating effectively for a sufficient period of time.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended ~~December~~March 31, ~~2024~~2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be involved in litigation relating to claims arising out of our operations and businesses that cover a wide range of matters, including, among others, contract and employment claims, personal injury claims, product liability claims and warranty claims. Currently, there are no claims or proceedings against us that we believe will have a material adverse effect on our business, financial condition, results of operations or cash flows. However, the results of any current or future litigation cannot be predicted with certainty and, regardless of the outcome, we may incur significant costs and experience a diversion of management resources as a result of litigation.

Item 1A. Risk Factors.

~~There~~Except as set forth below, there have been no material changes to the risk factors previously disclosed under the heading “Risk Factors” in our 2024 Form 10-K. You should carefully consider the risk factors in our 2024 Form 10-K and our other filings made with the SEC in addition to the risk factors set forth below. You should be aware that such risk factors and other information may not describe every risk we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Risks Relating to Our Business and Industry

Changes in trade policies, including the imposition of tariffs, could negatively impact our business, financial condition and results of operations.

The United States has implemented tariffs on a wide variety of goods across multiple countries and indicated that additional tariffs may be imposed. In addition, in response to such tariffs, some countries have announced or imposed tariffs on goods made in the United States. While the majority of our supply chain, including with respect to raw materials, is U.S.-based, we import certain raw materials, mainly steel and aluminum, and such imports may originate from countries that are currently subject to U.S.-based tariffs and may be subject to increased tariffs in the future. Further, while the vast majority of our sales comes from North America, increased or prolonged tariffs could indirectly depress demand for our products or increase the cost to manufacture our products by increasing the price of the materials used in our manufacturing processes, whether or not imported. Such decreased demand and/or increased manufacturing costs, as well as other adverse consequences of tariffs and other changes to U.S. and global trade policy, could hurt our competitive position and adversely impact our business, financial condition and results of operations.

Risks Relating to the Proposed Merger with James Hardie

Because the market price of James Hardie ordinary shares may fluctuate, holders of our common stock cannot be certain of the market value of the merger consideration they will receive in the Merger.

On March 23, 2025, we entered into the Merger Agreement with James Hardie. The Merger Agreement provides that, among other things and on the terms and subject to the conditions set forth therein, we will be merged with, and therefore become, an indirect wholly owned subsidiary of James Hardie at the Effective Time.

On the terms and subject to the conditions set forth in the Merger Agreement, at the Effective Time, each share of Company Common Stock, issued and outstanding immediately prior to the Effective Time (other than any shares of Company Common Stock held by us as treasury stock, directly by James Hardie or Merger Sub or by any dissenting stockholder) will be canceled and converted into the right to receive from James Hardie (i) $26.45 in cash, without interest, and (ii) 1.0340 James Hardie ordinary shares, as well as cash in lieu of fractional shares. The exchange ratio is fixed and will not be adjusted for changes in the market price of either James Hardie ordinary shares or Company Common Stock. Changes in the price of James Hardie ordinary shares prior to the Merger will affect the value that holders of Company Common Stock will receive in the Merger.

There will be a time lapse between the date of this Quarterly Report on Form 10-Q and the date on which our stockholders entitled to receive shares of James Hardie ordinary shares actually receive such shares. The market value of James Hardie ordinary shares may fluctuate during such period as a result of a variety of factors, including general market and economic conditions, regulatory considerations, including changes in U.S. monetary policy and its effect on global financial markets and on interest rates, changes in James Hardie’s or our business, operations and prospects and the impact that any of the foregoing may have on James Hardie, us or the customers or other constituencies of James Hardie or us, many of which factors are beyond James Hardie’s or our control.

The required regulatory approval for the Merger may not be received, may take longer than expected or may impose conditions that are not currently anticipated or that could have an adverse effect on the combined company following the Merger.

Before the Merger may be completed, the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or the HSR Act, relating to the completion of the Merger must have expired or been terminated. Under the Merger Agreement, we and James Hardie have each agreed to use our respective reasonable best efforts to obtain such authorizations and

Table of contents

consents, and James Hardie has agreed to take any and all steps necessary, subject to certain limitations set forth in the Merger Agreement, to avoid or eliminate impediments under any antitrust or certain other laws that may be asserted by any governmental authority so as to enable the completion of the Merger as promptly as practicable. However, there can be no assurance that this approval will be obtained in a timely fashion or at all, that regulators will not subject such approval to conditions, limitations, obligations or restrictions or that any such conditions, limitations, obligations or restrictions will not have the effect of delaying the completion of any of the transactions contemplated by the Merger Agreement, imposing additional material costs on or materially limiting the revenues of the combined company following the Merger or otherwise reducing the anticipated benefits of the Merger. If the consummation of the Merger is delayed, including by a delay in receipt of the required regulatory approval, our business, financial condition and results of operations may be materially adversely affected.

The Merger Agreement may be terminated in accordance with its terms, and the Merger may not be completed. Such failure to complete the transactions contemplated by the Merger Agreement could cause our results to be adversely affected or our stock price to decline.

The Merger Agreement contains certain termination rights for both James Hardie and us that, if exercised, would result in the Merger not being consummated. If the transactions contemplated by the Merger Agreement, including the Merger, are not completed for any reason, there may be various adverse consequences, and we may experience negative reactions from the financial markets, such as a decline in our stock price, and from our respective customers and employees. Furthermore, certain costs related to such transactions, such as legal, accounting and financial advisory fees, must be paid even if such transactions, including the Merger, are not completed. Moreover, we may be required to pay a termination fee of $272 million to James Hardie upon a termination of the Merger Agreement in certain circumstances, which are described in more detail below under the risk factor titled “The Merger Agreement limits our ability to pursue alternatives to the Merger and may discourage other companies from trying to acquire us.” If the Merger Agreement is terminated and we seek another merger or business combination, there can be no assurance that we will be able to find a party willing to engage in a transaction on more attractive terms than the Merger. A failure to complete the transactions contemplated by the Merger Agreement, whether because of a failure to receive the required approval of our stockholders, because of a failure to obtain the required regulatory approval or because we have breached our obligations in a way that permits James Hardie to terminate the Merger Agreement in accordance with its terms, or for any other reason, could cause our business, financial condition and results of operations to be materially adversely affected or our stock price to decline significantly, particularly to the extent that the current market price reflects a market assumption that the merger will be consummated.

We will be subject to business uncertainties and contractual restrictions while the Merger is pending.

During the period prior to the closing of the Merger and pursuant to the terms of the Merger Agreement, our business is exposed to certain incremental risks and contractual restrictions that could harm our business relationships, financial condition, results of operations, and business. Uncertainty about the effect of the Merger on employees and customers may have an adverse effect on us. This uncertainty may impair our ability to attract, retain and motivate key personnel until the Merger is completed, as such personnel may experience uncertainty about their future roles following the consummation of the Merger, and could cause customers, suppliers, vendors and others that deal with us to seek to change existing business relationships with us.

The pursuit of the Merger and the preparation for the integration may place a burden on our and James Hardie’s management and internal resources. Management’s and key personnel’s time and attention may be diverted from our ordinary business operations, and difficulties may be encountered in the transition and integration process, which may have a material adverse effect on each company’s business, financial condition and results of operations.

The Merger Agreement restricts us from taking certain actions without James Hardie’s consent. Under the terms of the Merger Agreement, subject to certain exceptions, we and James Hardie have agreed to use commercially reasonable efforts to conduct our respective businesses in the ordinary course prior to closing, and we and James Hardie have agreed not to take certain actions. These restrictions on the conduct of our business and our ability to take such actions could cause us to be unable to pursue beneficial opportunities, sell assets, incur indebtedness, engage in significant capital expenditures, enter into other transactions or make other changes to our business prior to the completion of the Merger. These restrictions could have a material adverse effect on our business, financial condition and results of operations.

The Merger Agreement limits our ability to pursue alternatives to the Merger and may discourage other companies from trying to acquire us.

The Merger Agreement contains “no shop” covenants that restrict our ability to, directly or indirectly, initiate, seek, solicit, knowingly encourage, knowingly facilitate, knowingly induce or knowingly take any other action that would reasonably be expected to lead to an acquisition proposal, engage in negotiations or discussions with any person (other than James Hardie and its representatives) relating to or in order to facilitate or encourage any acquisition proposal or provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any acquisition proposal, subject to certain exceptions.

The Merger Agreement further provides that, during the twelve (12)-month period following the termination of the Merger Agreement under specified circumstances, including the entry into a definitive agreement or consummation of a transaction with

Table of contents

respect to an alternative acquisition proposal, we may be required to pay a termination fee of $272 million to James Hardie. These provisions could discourage a potential third-party acquirer that might have an interest in acquiring all or a significant portion of our business from considering or proposing that acquisition.

The Merger will not be completed unless important conditions, including adoption of the Merger Agreement by our stockholders, are satisfied or waived.

Specified conditions set forth in the Merger Agreement must be satisfied or waived to complete the Merger. If the conditions are not satisfied or, subject to applicable law, waived, the Merger will not occur or will be delayed, and each of us and James Hardie may lose some or all of the intended benefits of the Merger. The following conditions must be satisfied or waived, if permissible, before we and James Hardie are obligated to complete the Merger: (i) adoption of the Merger Agreement by the requisite majority of our stockholders, (ii) authorization for listing on the New York Stock Exchange of the James Hardie ordinary shares to be issued in the Merger, subject to official notice of issuance, (iii) the expiration or termination of the applicable waiting period under the HSR Act, (iv) effectiveness of the registration statement on Form F-4 for the James Hardie ordinary shares to be issued in the Merger, and (v) the absence of any order or law after the date of the Merger Agreement enjoining or prohibiting the consummation of the Merger. The parties’ obligations to complete the Merger are also subject to certain additional customary conditions, including (a) subject to certain exceptions, the accuracy of the representations and warranties of the other party, (b) the absence of a Material Adverse Effect (as defined in the Merger Agreement) on the other party since the date of the Merger Agreement and (c) performance in all material respects by the other party of its obligations under the Merger Agreement.

Our stockholders will have a reduced ownership and voting interest after the Merger and will exercise less influence over management.

Our stockholders currently have the right to vote in the election of our board of directors and on other matters affecting us. Upon the completion of the Merger, our stockholders will be stockholders of James Hardie with a percentage ownership of James Hardie that is smaller than such stockholders’ current percentage ownership of us. Upon completion of the transaction, former holders of Company Common Stock are expected to own approximately 26% of the combined company. Because of this, our stockholders will have less influence on the management and policies of the combined company than they now have on our management and policies.
