Introductory Note

This Current Report on Form 8-K is being filed in connection with the completion on July 1, 2025 of the previously announced transactions contemplated by that certain Agreement and Plan of Merger, dated as of March 23, 2025 (as amended, the “Merger Agreement”), by and among The AZEK Company Inc., a Delaware corporation (the “Company”), James Hardie Industries plc (“JHX”) and Juno Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of JHX (“Merger Sub”).

Pursuant to the Merger Agreement, on July 1, 2025, Merger Sub merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of JHX.

At the effective time of the Merger (the “Effective Time”), on the terms and subject to the conditions of the Merger Agreement, 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 JHX or by any dissenting stockholder) was canceled and converted into the right to receive $26.45 in cash, without interest, from JHX less any applicable withholding taxes (the “Cash Consideration”), and 1.0340 ordinary shares (the “Exchange Ratio”), par value EUR 0.59 per share, of JHX and cash in lieu of fractional shares (collectively, the “Merger Consideration”).

At Effective Time, on the terms and subject to the conditions of the Merger Agreement, each then-outstanding equity award with respect to Company Common Stock was treated as follows:

•

Restricted Stock Unit Awards (“Company RSU Awards”): Each then-outstanding Company RSU Award that was held by a non-employee director of the Company was fully vested and canceled in exchange for the right to receive the Merger Consideration, less applicable tax withholdings. Each then-outstanding Company RSU Award, other than those held by any non-employee directors of the Company, was assumed by JHX and converted into (A) a time-based restricted stock unit award of JHX (each, a “JHX RSU Award”) covering a number of JHX ordinary shares (rounded to the nearest whole number of shares) equal to the product obtained by multiplying (1) the number of shares of Company Common Stock subject to the Company RSU Award by (2) the Exchange Ratio and (B) a cash award (a “JHX Cash Award”) having a value equal to the product obtained by multiplying (1) the number of shares of Company Common Stock subject to the Company RSU Award by (2) the Cash Consideration. Each JHX RSU Award and each JHX Cash Award is subject to the same terms and conditions as were applicable to such award immediately prior to the Effective Time, including the vesting schedule applicable to the corresponding Company RSU Award.

•

Performance-Based Stock Unit Awards (“Company PSU Awards”): Each then-outstanding Company PSU Award was assumed by JHX and converted into (A) a JHX RSU Award covering a number of JHX ordinary shares (rounded to the nearest whole number of shares) equal to the product obtained by multiplying (1) the number of shares of Company Common Stock subject to the Company PSU Award by (2) the Exchange Ratio and (B) a JHX Cash Award having a value equal to the product obtained by multiplying (1) the number of shares of Company Common Stock subject to the Company PSU Award by (2) the Cash Consideration. Each JHX RSU Award and each JHX Cash Award is subject to the same terms and conditions as were applicable to such award immediately prior to the Effective Time, including the vesting schedule applicable to the corresponding Company PSU Award, but is not subject to any performance conditions following the closing. For purposes of the foregoing calculations, the number of shares of Company Common Stock subject to the Company PSU Award was determined based on (i) for fiscal years 2024 and 2025, actual performance and (ii) for fiscal years 2026 and 2027, target performance.

•

Stock Options (“Company Stock Options”): Each then-outstanding Company Stock Option held by a non-employee director of the Company (other than Jesse Singh, Gary Hendrickson or Howard Heckes) or a former employee of the Company was canceled for the right to receive an amount in cash equal to the value of the Merger Consideration, less the exercise price and

applicable tax withholdings. All other then-outstanding Company Stock Options were assumed by JHX and converted into an option to purchase a number of JHX ordinary shares (rounded down to the nearest whole number of shares) (“JHX Share Option”) equal to the product of (A) the number of shares of Company Common Stock subject to such Company Stock Option multiplied by (B) the Equity Award Exchange Ratio, with an exercise price per JHX ordinary share equal to the quotient (rounded up to the nearest whole cent) obtained by dividing (A) the exercise price per share of Company Common Stock subject to such Company Stock Option by (B) the Equity Award Exchange Ratio. The Equity Award Exchange Ratio is defined as the sum of (A) the quotient (rounded to four (4) decimal places) obtained by dividing (x) the Cash Consideration by (y) JHX’s five-trading day volume-weighted average price ending on the trading day immediately prior to the closing date and (B) the Exchange Ratio. Each JHX Share Option will be subject to the same terms and conditions as were applicable to such award immediately prior to the Effective Time, including the vesting schedule applicable to the corresponding Company Stock Option.

The JHX ordinary shares issued in connection with the Merger were registered under the Securities Act of 1933, as amended, pursuant to a registration statement on Form F-4 (File No. 333-286977) filed by JHX with the U.S. Securities and Exchange Commission (the “SEC”) and declared effective on May 29, 2025 (the “Registration Statement”). The joint proxy statement/prospectus included in the Registration Statement contains additional information about the Merger Agreement and the transactions contemplated thereby.
