*Forward-Looking Statements*

This Form 6-K contains forward-looking statements. James Hardie Industries plc (the "Company") may from time to time make forward-looking statements in its periodic reports filed with or furnished to the Securities and Exchange Commission, on Forms 20-F and 6-K, in its annual reports to shareholders, in offering circulars, invitation memoranda and prospectuses, in media and earnings releases and other written materials and in oral statements made by the Company's officers, directors or employees to analysts, institutional investors, existing and potential lenders, representatives of the media and others. Statements that are not historical facts are forward-looking statements and such forward-looking statements are statements made pursuant to the Safe Harbor Provisions of the Private Securities Litigation Reform Act of 1995.

Examples of forward-looking statements include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements about the acquisition of AZEK, including its anticipated benefits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements about the Company's future performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• projections of the Company's results of operations or financial condition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements regarding the Company's plans, objectives or goals, including those relating to strategies, initiatives, competition, acquisitions, dispositions and/or its products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expectations concerning the costs associated with the suspension or closure of operations at any of the Company's plants and future plans with respect to any such plants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expectations concerning the costs associated with the significant capital expenditure projects at any of the Company's plants and future plans with respect to any such projects;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expectations regarding the extension or renewal of the Company's credit facilities including changes to terms, covenants or ratios;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expectations concerning dividend payments and share buy-backs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements concerning the Company's Corporate and tax domiciles and structures and potential changes to them, including potential tax charges;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements regarding tax liabilities and related audits, reviews and proceedings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements regarding the possible consequences and/or potential outcome of legal proceedings brought against us and the potential liabilities, if any, associated with such proceedings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expectations about the timing and amount of contributions to AICF, a special purpose fund for the compensation of proven Australian asbestos-related personal injury and death claims;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements regarding the Company's ability to manage legal and regulatory matters (including but not limited to product liability, environmental, intellectual property and competition law matters) and to resolve any such pending legal and regulatory matters within current estimates and in anticipation of certain third-party recoveries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements about economic or housing market conditions in the regions in which we operate, including but not limited to, the levels of new home construction and home renovations, unemployment levels, changes in consumer income, changes or stability in housing values, the availability of mortgages and other financing, mortgage and other interest rates, housing affordability and supply, the levels of foreclosures and home resales, currency exchange rates, and builder and consumer confidence.

Words such as "believe," "anticipate," "plan," "expect," "intend," "target," "estimate," "project," "predict," "forecast," "guideline," "aim," "will," "should," "likely," "continue," "may," "objective," "outlook" and similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. Readers are cautioned not to place undue reliance on these forward-looking statements and all such forward-looking statements are qualified in their entirety by reference to the following cautionary statements.

------

<u>[**Table of Contents**](#i480ebf4f47bd479489eb168a52b950cb_4)</u>

Forward-looking statements are based on the Company's current expectations, estimates and assumptions 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 Company's control. 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 these forward-looking statements. These factors, some of which are discussed under "Risk Factors" in Section 3 of our Form 20-F filed with the Securities and Exchange Commission on 20 May 2025, include, but are not limited to: all matters relating to or arising out of the prior manufacture of products that contained asbestos by current and former Company subsidiaries; required contributions to AICF, any shortfall in AICF funding and the effect of currency exchange rate movements on the amount recorded in the Company's financial statements as an asbestos liability; compliance with and changes in tax laws and treatments; competition and product pricing in the markets in which the Company operates; the consequences of product failures or defects; exposure to environmental, asbestos, putative consumer class action or other legal proceedings; general economic and market conditions; the supply and cost of raw materials; possible increases in competition and the potential that competitors could copy the Company's products; compliance with and changes in environmental and health and safety laws; risks of conducting business internationally; compliance with and changes in laws and regulations; currency exchange risks; dependence on customer preference and the concentration of the Company's customer base; dependence on residential and commercial construction markets; the effect of adverse changes in climate or weather patterns; use of accounting estimates; the AZEK acquisition; and all other risks identified in the Company's reports filed with Australian, Irish and US securities regulatory agencies and exchanges (as appropriate). The Company cautions you that the foregoing list of factors is not exhaustive and that other risks and uncertainties may cause actual results to differ materially from those referenced in the Company's forward-looking statements. Forward-looking statements speak only as of the date they are made and are statements of the Company's current expectations concerning future results, events and conditions. The Company assumes no obligation to update any forward-looking statements or information except as required by law.

As the disclosure of cases of acting in concert may vary due to the specific circumstances (e.g. same or different total positions of the parties, entering or exiting of acting in concert by a single party) the standard form does not provide for a specific method how to notify cases of acting in concert. In relation to the transactions referred to in points (b) to (h) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the following list is provided as an indication of the persons who should be mentioned: - in the circumstances foreseen in letter (b) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the natural person or legal entity that acquires the voting rights and is entitled to exercise them under the agreement and the natural person or legal entity who is transferring temporarily for consideration the voting rights; - in the circumstances foreseen in letter (c) of the Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the natural person or legal entity holding the collateral, provided the person or entity controls the voting rights and declares its intention of exercising them, and natural person or legal entity lodging the collateral under these conditions; - in the circumstances foreseen in letter (d) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the natural person or legal entity who has a life interest in shares if that person or entity is entitled to exercise the voting rights attached to the shares and the natural person or legal entity who is disposing of the voting rights when the life interest is created; - in the circumstances foreseen in letter (e) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the controlling natural person or legal entity and, provided it has a notification duty at an individual level under Regulation 14 of the Regulations (Article 9 of Directive 2004/109/EC), under letters (a) to (d) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC) or under a combination of any of those situations, the controlled undertaking; - in the circumstances foreseen in letter (f) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the deposit taker of the shares, if he can exercise the voting rights attached to the shares deposited with him at his discretion, and the depositor of the shares allowing the deposit taker to exercise the voting rights at his discretion; - in the circumstances foreseen in letter (g) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the natural person or legal entity that controls the voting rights; - in the circumstances foreseen in letter (h) of Regulation 15 of the Regulations (Article 10 of Directive 2004/109/EC), the proxy holder, if he can exercise the voting rights at his discretion, and the shareholder who has given his proxy to the proxy holder allowing the latter to exercise the voting rights at his discretion (e.g. management companies). v Applicable in the cases provided for in Regulation 15(b) to (h) of the Regulations (Article 10 (b) to (h) of Directive 2004/109/EC). This should be the full name of the shareholder who is the counterparty to the natural person or legal entity referred to in Regulation 15 of the Regulations (Article 10 Directive 2004/109/EC) unless the percentage of voting rights held by the shareholder is lower than the lowest notifiable threshold for the disclosure of voting rights holdings in accordance with the requirements of the Regulations and the Transparency Rules. vi The date on which threshold is crossed or reached should be the date on which the acquisition or disposal took place or the other reason triggered the notification obligation. For passive crossings, the date when the corporate event took effect.

------

![](ex991changeinsubstantial007.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;vii The total number of voting rights shall be composed of all the shares, including depository receipts representing shares, to which voting rights are attached even if the exercise thereof is suspended. viii If the holding has fallen below the lowest applicable threshold in accordance with the Regulations and the Transparency Rules the holder is not obliged to disclose the extent of the holding only that the holding is "below 3%" or "below 5%" as appropriate. ix In case of combined holdings of shares with voting rights attached "direct holding" and voting rights "indirect holding", please split the voting rights number and percentage into the direct and indirect columns – if there is no combined holdings, please leave the relevant box blank. x Date of maturity/expiration of the financial instrument i.e. the date when right to acquire shares ends. xi If the financial instrument has such a period – please specify this period – for example once every 3 months starting from [date]. xii In case of cash settled instruments the number and percentages of voting rights is to be presented on a delta-adjusted basis (Regulation 17(4) of the Regulations/Article 13(1a) of Directive 2004/109/EC). xiii If the person subject to the notification obligation is either controlled and/or does control another undertaking then the second option applies. xiv The full chain of controlled undertakings, starting with the ultimate controlling natural person or legal entity, has to be presented also in cases in which only on subsidiary level a threshold is crossed or reached and the subsidiary undertaking discloses the notification, as only thus will the markets get a full picture of the group holdings. In the case of multiple chains through which the voting rights and/or financial instruments are effectively held, the chains have to be presented chain by chain leaving a row free between different chains (e.g.: A, B, C, free row, A, B, D, free row, A, E, F etc.). xv The names of controlled undertakings through which the voting rights and/or financial instruments are effectively held have to be presented irrespective of whether the controlled undertakings cross or reach the lowest applicable threshold themselves. xvi Example: Correction of a previous notification.
