Item 1.01. Entry into a Material Definitive Agreement.

On May 4, 2025, The AZEK Company Inc., a Delaware corporation (the “Company”), entered into Amendment No. 1 (the “Amendment”) to the Agreement and Plan of Merger (the “Merger Agreement”) which had previously been entered into on March 23, 2025 by and among the Company, James Hardie Industries plc, an Irish public limited company (“JHX”), and Juno Merger Sub Inc., a Delaware corporation and an indirect wholly owned subsidiary of JHX (“Merger Sub”). Capitalized terms used in this Current Report on Form 8-K but not otherwise defined herein have the meanings assigned to them in the Merger Agreement, a copy of which is filed as Exhibit 2.1 to the Current Report on Form 8-K filed by the Company with the U.S. Securities and Exchange Commission on March 24, 2025.

The Amendment revises the treatment of Company Stock Options in connection with the completion of the Merger to provide that, as of the Effective Time, Company Stock Options held by former employees of the Company or by non-employee members of the Company Board, other than the Company Board Designees (Jesse Singh, Gary Hendrickson and Howard Heckes), will be canceled for the right to receive an amount in cash equal to the value of the Merger Consideration, net of the exercise price and applicable tax withholding. All other Company Stock Options will be assumed by JHX and converted into a number of options to purchase ordinary shares of JHX, on the same terms and conditions as were applicable to such Company Stock Options.

Other than as expressly modified pursuant to the Amendment, the Merger Agreement remains in full force and effect as originally executed on March 23, 2025.

The foregoing description of the Amendment in this Current Report on Form 8-K is only a summary, does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, which is attached hereto as Exhibit 2.1 and incorporated by reference herein.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On May 2, 2025, pursuant to the Merger Agreement, the Compensation Committee of the Board approved cash retention awards in the amount of $400,000 to each of Ryan Lada, Jonathan Skelly, Samara Toole and Morgan Walbridge. The retention awards vest in equal installments upon the Closing and upon the six-month anniversary of the Closing, subject to employment through the applicable vesting date, or upon a termination of the recipient’s employment by JHX and its affiliates (including the Company) without cause or by the recipient for good reason following the Closing but prior to the six-month anniversary of the Closing, subject to the recipient’s execution of a release of claims in favor of JHX and its affiliates (including the Company). The foregoing summary of the cash retention awards is not complete and is qualified in its entirety by reference to the full and complete terms of the awards, the form of which is attached to this Current Report on Form 8-K as Exhibit 10.1.

Cautionary Disclosure Regarding Forward-Looking Statements

Statements in this report, including statements regarding the proposed acquisition of the Company by JHX, that are not historical facts are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Rule 175 promulgated thereunder, and Section 21E of the Securities Exchange Act of 1934, as amended, and Rule 3b-6 promulgated thereunder, which statements involve inherent risks and uncertainties and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Examples of forward-looking statements include statements about the anticipated benefits of the proposed transaction between JHX and the Company (the “Transaction”), including estimated synergies, and the expected timing of completion of the Transaction; statements about the Company’s future performance; and statements regarding the Company’s plans, objectives or goals. Words such as “believe,” “anticipate,” “plan,” “expect,” “intend,” “target,” “estimate,” “project,” “predict,” “trend,” “forecast,” “guideline,” “aim,” “objective,” “will,” “should,” “could,” “likely,” “continue,” “may,” “objective,” “outlook” and similar expressions may identify forward-looking statements but are not the exclusive means of identifying such statements. Investors are cautioned not to place undue reliance on forward‑looking statements.

Forward-looking statements of JHX and the Company, respectively, are based on the current expectations, estimates and assumptions of JHX and the Company, respectively, and, because forward-looking statements address future results, events and conditions, they, by their very nature, involve inherent risks and uncertainties, many of which are unforeseeable and beyond the control of JHX or the Company. Such known and unknown risks, uncertainties and other factors may cause actual results, performance or other achievements to differ materially from the anticipated results, performance or achievements expressed, projected or implied by forward-looking statements. These factors include risks and uncertainties relating to the Transaction, including, but not limited to, the possibility that required regulatory approvals for the Transaction or approval of the Transaction by the Company’s stockholders and other conditions to closing are not received or satisfied on a timely basis or at all; the possible occurrence of events that may give rise to a right of either or both of JHX and the Company to terminate the merger agreement providing for the Transaction; possible negative effects of the announcement or the consummation of the Transaction on the market price of JHX’s and/or the Company’s shares and/or on their respective businesses, financial conditions, results of operations and financial performance; uncertainties as to access to financing (including financing for the Transaction) on a timely basis and on reasonable terms; the impact of the additional indebtedness the Company would incur in connection with the Transaction; risks relating to the value of the JHX shares to be issued in the Transaction and the contemplated listing arrangements for JHX shares and depositary interests following the Transaction; risks relating to significant transaction costs and/or unknown liabilities; the possibility that the anticipated synergies and other benefits from the Transaction cannot be realized in full or at all or may take longer to realize than expected; risks associated with contracts containing consent and/or other provisions that may be triggered by the Transaction; risks associated with Transaction-related litigation; the possibility that costs or difficulties related to the integration of JHX’s and the Company’s businesses will be greater than expected; the risk that the Transaction and its announcement could have an adverse effect on the parties’ relationships with its and their employees and other business partners, including suppliers and customers; the potential for the Transaction to divert the time and attention of management from ongoing business operations; the potential for contractual restrictions under the merger agreement providing for the Transaction to adversely affect the parties’ ability to pursue other business opportunities or strategic transactions; the risk of other Transaction‑related disruptions to the businesses, including business plans and operations, of JHX and the Company; and the possibility that, as a result of the Transaction or otherwise, JHX could lose its foreign private issuer status and be required to bear the costs and expenses related to full compliance with rules and regulations that apply to U.S. domestic issuers. There can be no assurance that the Transaction will in fact be consummated in the manner described or at all.

These factors are not necessarily all of the factors that could cause JHX’s, the Company’s or the combined company’s actual results, performance or achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other factors, including unknown or unpredictable factors, could also harm JHX’s, the Company’s or the combined company’s results.

The foregoing discussion of risks and uncertainties is not exhaustive; other risks and uncertainties may cause actual results to differ materially from those referenced in any forward‑looking statements. All forward-looking statements attributable to JHX, the Company or the combined company, or persons acting on JHX’s or the Company’s behalf, are expressly qualified in their entirety by the cautionary statements set forth above. Forward‑looking statements in this report speak only as of the date of this report and are statements of then‑current expectations concerning future results, events and conditions. Neither JHX nor the Company assumes any obligation to update any forward‑looking statements or information except as required by law. If JHX or the Company updates one or more forward-looking statements, no inference should be drawn that JHX or the Company will make additional updates with respect to those or other forward-looking statements. Further information regarding JHX, the Company and factors that could affect the forward-looking statements contained herein can be found in JHX’s Annual Report on Form 20-F for the fiscal year ended March 31, 2024, and in its other documents filed or furnished with the U.S. Securities and Exchange Commission (“SEC”), and in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2024, and in its other documents filed or furnished with the SEC.
