*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**](#i53c7612f7a5b48448fec00133d0a179f_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.

7Notice of Annual General Meeting 2025 VOTING AND PARTICIPATION IN THE ANNUAL GENERAL MEETING If you are a registered holder of Shares as at 8:00am (Dublin time) / 4:00am (New York time) / 7:00pm (Sydney time) on Tuesday, 28 October 2025, you may attend, speak and vote, in person or appoint a proxy (who need not be a shareholder) to attend, speak and vote on your behalf, at the AGM. See "Voting on the Resolutions" below for information on how you can vote or appoint a proxy. AGM Details The AGM will be held at James Hardie's Corporate Headquarters, 1st Floor, Block A, One Park Place, Upper Hatch Street, Dublin 2, D02 FD79, Ireland, starting at 8:00pm (Dublin time) / 4:00pm (New York time) on Wednesday, 29 October 2025 / 7:00am (Sydney time) on Thursday, 30 October 2025. Shareholder Categories The process for voting and/or appointing a proxy in connection with the resolutions to be proposed at the AGM depends on the manner in which you hold your Shares. In this Notice of Meeting: (a) Registered Holder refers to persons entered on the Register (i.e., those shareholders whose shareholding is evidenced by their holding statement and who do not hold their interests in Shares as Beneficial Holders or CDI Holders). (b) Beneficial Holders refers to persons who hold their interests in the Shares in a stock brokerage account or otherwise via a broker, bank or other nominee that is a participant in DTC. (c) CDI Holders refers to holders of the Company's CDIs entered in the CDI register of the Company. Voting on the Resolutions How you vote at the AGM or appoint a proxy will depend on whether you are a Registered Holder, Beneficial Holder or CDI Holder, as follows: (a) Registered Holders If you are a Registered Holder, you may attend the AGM to vote by ballot or vote by proxy in advance of the deadline for voting by proxy of 8:00am (Dublin time) / 4.00am (New York time) / 7:00pm (Sydney time) on Tuesday, 28 October 2025, by using one of the following methods: (i) online by visiting envisionreports.com/jhx or scanning the QR code and following the instructions on your form of proxy; or (ii) by mail, if you are a Registered Holder that received printed AGM materials, by following the instructions on your form of proxy and returning the completed form of proxy in the postage-paid envelope accompanying the AGM materials. As a Registered Holder you may also appoint a proxy by completing and returning the form of proxy enclosed with this Notice of Meeting (or a proxy in the form set out in Section 184 of the Irish Companies Act 2014) to Computershare Investor Services, PO BOX 43101, Providence, RI 02940-5607 to be received no later than 8:00am (Dublin time) / 4:00am (New York time) / 7:00pm (Sydney time) on Tuesday, 28 October 2025. A proxy is not required to be a shareholder of the Company. Appointment of a proxy does not preclude shareholders from attending and voting at the AGM should they wish to do so. In the case of joint holders, the vote of the senior who tenders a vote, whether in person or by proxy, will be accepted to the exclusion of the votes of the other Registered Holder(s), and, for this purpose, seniority will be determined by the order in which the names stand in the Register. (b) Beneficial Holders If you are a Beneficial Holder, this document is being made available or forwarded to you by or on behalf of your broker, bank or other nominee. Only those Beneficial Holders holding their interest in Shares as of the Record Date, or, if the AGM is adjourned, on such other date as is communicated to Beneficial Holders, are entitled to vote on the resolutions in respect of such Shares. Beneficial Holders may direct their broker, bank or other nominee on how to vote their Shares by following the instructions for voting on the DTC voting instruction form provided by your broker, bank or other nominee. If you are a Beneficial Holder and do not direct your broker, bank or other nominee on how to vote your Shares on your DTC voting instruction form, your Shares will not be voted at the AGM for any matter that is considered to be "non-routine" under the rules of the New York Stock Exchange (the NYSE). We believe that, under the rules of the NYSE, the only matter of business at the AGM that will be considered "routine" and on which your broker can vote your Shares without receiving instructions from you is Resolution 4. We believe that, under the rules of the NYSE, your broker will not have discretionary authority to vote your Shares on any other resolutions at the AGM. We encourage you to communicate your

17Notice of Annual General Meeting 2025 Resolution 5 asks shareholders to approve the grant of ROCE RSUs under the 2006 LTIP to James Hardie's Director and CEO, Aaron Erter. The People & Remuneration Committee has allocated the Long-Term Incentive (LTI) target of the CEO (and each senior executive) between the following three components to ensure that the reward is based on a diverse range of factors which validly reflect longer term performance, as well as provide an appropriate incentive to ensure senior executives focus on the key areas which will drive shareholder value creation over the medium and long-term. For fiscal year 2026, we reviewed the LTI program and made certain adjustments, in part, based on feedback from our investors. The overall LTI maximum payout was reduced from 250% of target to 233% of target by applying an equal weighting for all three vehicles as shown below: n One-third (formerly 25%) to ROCE RSUs (maximum payout of 200%) – an indicator of James Hardie's capital efficiency over time; n One-third (formerly 25%) to Relative TSR RSUs (maximum payout of 200%) – an indicator of James Hardie's performance relative to the constituent companies making up the S&P 500 index as of the date of grant; and n One-third (formerly 50%) to Scorecard LTI (maximum payout of 300%) – an indicator of each senior executive's contribution to James Hardie achieving its long-term strategic goals. The Board and People & Remuneration Committee believe the LTI program is achieving the stated objectives, that management understands the current LTI program and continues to be motivated by it and the LTI components for fiscal year 2026 are materially consistent with the components for fiscal year 2025. Reasons for ROCE RSUs ROCE RSUs shall vest if James Hardie's ROCE performance meets or exceeds ROCE performance hurdles over a three-year period, subject to the exercise of negative discretion by the People & Remuneration Committee. James Hardie introduced ROCE RSUs in fiscal year 2013 once the US housing market had stabilised to an extent which permitted the setting of multi-year financial metrics. As James Hardie funds capacity expansions and market initiatives in the US, Asia Pacific and Europe, it is important that management focuses on ensuring that the Company continues to achieve strong ROCE results while pursuing growth. Upon vesting, ROCE RSUs shall be settled in either Shares listed and traded on the New York Stock Exchange or in CDIs on a 1-to-1 basis. ROCE RSU Changes for Fiscal Year 2026 As noted above, the weighting of the ROCE RSUs has been increased from 25% to one-third of the overall LTI target. Following the merger with The AZEK Company Inc., the ROCE performance scale has been updated to reflect the current guidance for the combined organization. As this is an early stage for forecasting, future ROCE goals will be set once the combined company's financials are more fully established. 2027 and 2028 will also be designed once the combined company's financials are established for those respective years. That said, the remaining design features of the fiscal year 2026 ROCE RSUs are generally consistent with those of the fiscal year 2025 ROCE RSUs. Key Aspects of ROCE RSUs Goal Setting: ROCE performance hurdles for the ROCE RSUs are based on current guidance of the combined organization and take into account the forecasts for the US, Europe and Asia Pacific housing markets. ROCE Definitions: The ROCE measure will be determined by dividing adjusted earnings before interest and taxes (Adjusted EBIT) by adjusted capital employed (Adjusted Capital Employed) each as further explained below. The Adjusted EBIT component of the ROCE measure will be as reported in James Hardie's financial results, comprised of earnings before interest and taxes and including incremental depreciation expense resulting from the application of purchase accounting step- up to property, plant and equipment, as adjusted by: n excluding the earnings impact of legacy issues (such as asbestos adjustments); n excluding acquisition-related expenses; n excluding non-cash amortization of intangibles from the AZEK acquisition; and n adding back asset impairment charges, restructuring charges and excluding performance from any business held for sale in the relevant period, unless otherwise determined by the People & Remuneration Committee. RESOLUTION 5 – GRANT OF RETURN ON CAPITAL EMPLOYED RESTRICTED STOCK UNITS TO CEO

------

![](ex9912jhx2025agmmaterial019.jpg)

18Notice of Annual General Meeting 2025 The Adjusted Capital Employed component of the ROCE measure will be determined as follows: total assets minus current liabilities, as reported in James Hardie's financial results, adjusted by: n excluding balance sheet items related to legacy issues (such as asbestos adjustments), dividends payable and deferred and current taxes; n excluding intangible assets including goodwill and other intangibles; n excluding accrued product liability warranties; n adding back asset impairment charges in the relevant period, unless otherwise determined by the People & Remuneration Committee; n adding back leasehold assets for manufacturing facilities and other material leased assets; n deducting all greenfield construction-in-progress, and any brownfield construction-in-progress projects involving capacity expansion that are individually greater than US$20 million, until such assets reach commercial production and are transferred to the fixed asset register; n excluding assets from any business or asset held for sale; and n excluding cash and short-term debt. The resulting Adjusted Capital Employed for each quarter of any fiscal year will be averaged using the balance at the end of each of the four quarters of each fiscal year to better reflect capital employed over the course of a year rather than at a certain point in time. The ROCE result to compare to the performance hurdles will be the average of James Hardie's ROCE in fiscal years 2026, 2027 and 2028. These definitions have been framed to ensure management is rewarded and held accountable for the aspects over which they have direct influence and control, while not discouraging management from recommending that James Hardie undertake investments that will provide for future Company growth. Grant: The CEO will receive a grant for fiscal year 2026 equal to the maximum number of ROCE RSUs (2.0x target). The number of ROCE RSUs which vest, and the number of Shares ultimately received in 2028 will depend on James Hardie's ROCE performance in fiscal years 2026 through 2028 together with the People & Remuneration Committee's exercise of negative discretion, if exercised. Performance Hurdle and Period: The performance hurdles for ROCE RSUs granted in fiscal year 2026 (for performance in fiscal years 2026 through 2028) are: Performance period: The overall performance period is three years. The ROCE RSUs shall vest on 17 August 2028, subject to performance and the exercise of negative discretion by the People & Remuneration Committee, if exercised. Conditions and negative discretion: In 2028, the People & Remuneration Committee will review James Hardie's performance over the performance period and may exercise negative discretion to reduce the number of ROCE RSUs that would otherwise vest under the ROCE vesting scale above based on the quality of the ROCE returns balanced against management's delivery of market share growth and performance against certain specified strategic goals and objectives (i.e., the Scorecard). The People & Remuneration Committee can only exercise negative discretion. It cannot be applied to enhance the reward that can be received. The potential to exercise negative discretion allows the People & Remuneration Committee to ensure that ROCE returns are not obtained at the expense of long-term sustainability. The Scorecard includes several longer-term measures which the People & Remuneration Committee believes are important contributors to long-term creation of shareholder value. Each year the People & Remuneration Committee approves several key objectives and the measures it expects to see achieved for each of these objectives. The fiscal year 2026 Scorecard applicable for the grant of ROCE RSUs (and Scorecard LTI) is set out in the Supplement to the Remuneration Report which is available on the Shareholder Meetings page on James Hardie's Investor Relations website (https://ir.jameshardie.com.au/jh/shareholder_meetings.jsp). The People & Remuneration Committee considers the goals to be reflective of James Hardie's overall long-term goals. ROCE AMOUNT OF TARGET ROCE RSUS TO VEST < 25.0% 0.0x ≥ 25.0% but < 28.5% 0.5x ≥ 28.5% but < 32.0% 1.0x ≥ 32.0% but < 35.0% 1.5x ≥ 35.0% 2.0x

19Notice of Annual General Meeting 2025 The CEO's rating ultimately depends on the People & Remuneration Committee's assessment (and the Board's review) of his contribution to James Hardie in meeting the Scorecard objectives. Although most of the objectives in the Scorecard have quantitative targets, the Board has not allocated a specific weighting to any and the final Scorecard assessment and exercise of negative discretion (if any) will involve an element of judgment by the People & Remuneration Committee. A different amount of negative discretion is likely to be applied when assessing the CEO's performance for the Scorecard LTI grants (which only include consideration of Scorecard measures) and ROCE RSUs grants (which involve a broader assessment of the quality of James Hardie's results). Worked Example The following example uses the CEO's ROCE RSU LTI target quantum of US$2,033,333 and assumes for illustrative purposes, a three- year average ROCE performance of 33.5%: At grant date, the LTI quantum granted to the CEO in ROCE RSUs is: US$6,100,000 LTI target / 1/3 of LTI target issued in ROCE RSUs x 2.0 target leverage = US$4,066,667 to be granted in ROCE RSUs. At a USD value equivalent to AUD 30.13 per Share, this is equivalent to a maximum grant of 207,010 ROCE RSUs. Based on an average 33% ROCE result for the three-year period to fiscal year 2028, 1.5x target would be eligible to vest: 207,010 RSUs x 75% = 155,258 ROCE RSUs. Note: 1.5x target equals 75% of total ROCE RSUs granted. At the conclusion of the three-year performance period, the People & Remuneration Committee will review James Hardie's performance and decide if they should apply negative discretion to reduce the number of ROCE RSUs which vest. For example: assuming that the People & Remuneration Committee determines that 1.0x target (rather than the 1.5x target based on performance against the ROCE performance hurdles) of the CEO's total ROCE RSUs should vest, the CEO would receive: 207,010 RSUs x 50% = 103,505 ROCE RSUs. Note: 1.0x target equals 50% of total ROCE RSUs granted. Maximum and actual number of ROCE RSUs The maximum number of Shares and ROCE RSUs for which approval is sought under this Resolution 5 is 260,000 and is based on the grant that would be made if James Hardie's performance warranted the maximum possible award for fiscal year 2026 – fiscal year 2028 (i.e., 2.0x of LTI target) and the People & Remuneration Committee did not exercise any negative discretion to reduce the number of ROCE RSUs which ultimately are to vest and be settled into Shares. The 260,000 figure is based on a stock price assumption of AUD 24.00. The actual number of ROCE RSUs granted is determined by dividing the maximum dollar amount granted under the ROCE RSUs portion of the LTI target (which is 2.0x each LTI target) by James Hardie's share price over the 20 trading days preceding the date of grant, subject to the maximum specified in Resolution 5. In the unlikely event the grant calculation returns an actual number of ROCE RSUs to be granted that is greater than the maximum number of Shares for which approval is sought under this Resolution 5, James Hardie may grant a cash settled award equal in value to the number of ROCE RSUs which exceed the maximum number of Shares. Any such cash settled award made will vest on the same criteria as set forth above and would only vest in the event the ROCE RSU grant vests based on performance. Previous grants For fiscal year 2026, as CEO of James Hardie, Aaron Erter is eligible to participate in the 2006 LTIP. The maximum number of ROCE RSUs granted to Aaron Erter since joining James Hardie in September 2022, excluding the grants that are the subject of Resolution 5, is set out in the table below: DATE OF GRANT NUMBER GRANTED VESTING DATE 03 November 2022 19,862 17 August 2023 03 November 2022 19,862 17 August 2024 03 November 2022 79,450 17 August 2025 17 August 2023 92,265 17 August 2026 17 August 2024 89,621 17 August 2027

20Notice of Annual General Meeting 2025 There was no consideration paid by, and James Hardie did not provide loans to, the CEO in relation to the grant of these ROCE RSUs. General ROCE RSUs will be granted in accordance with the terms of the 2006 LTIP and on the basis set out in these Explanatory Notes. Currently, Aaron Erter is the only Director of James Hardie entitled to participate in the 2006 LTIP. ROCE RSUs will be granted for no consideration and James Hardie will not provide loans to the CEO in relation to the grant of ROCE RSUs. Subject to the performance hurdles being met and the People & Remuneration Committee's exercise of negative discretion (if any), the CEO will be entitled to receive Shares upon vesting of the ROCE RSUs for no consideration. ROCE RSUs will be granted to the CEO no later than 12 months after the passing of Resolution 5. Summary of the legal requirements for seeking shareholder approval ASX Listing Rule 10.14 (specifically, ASX Listing Rule 10.14.1) provides that a listed company must not permit a director to acquire shares or rights to be issued shares under an employee incentive scheme without the approval of shareholders by ordinary resolution. Resolution 5 seeks the required shareholder approval to approve the grant of RSUs under the 2006 LTIP under and for the purposes of ASX Listing Rule 10.14.1 to James Hardie's CEO, Aaron Erter, for fiscal year 2026 on the basis set out above. Aaron Erter's current total remuneration at the date of this Notice of Meeting is USD$8,694,400, including cash compensation of USD$2,594,400, long-term cash compensation of USD$2,033,333 and share-based compensation of USD$4,066,667. If Resolution 5 is passed, the Company will be able to proceed with the grant of ROCE RSUs, under the 2006 LTIP to Aaron Erter, for fiscal year 2026 on the basis set out above. Details of any ROCE RSUs issued under the 2006 LTIP will be published in James Hardie's annual report relating to the period in which they are issued, along with a statement that approval for the issue was obtained under ASX Listing Rule 10.14. Any additional persons covered by ASX Listing Rule 10.14 who become entitled to participate in an issue of ROCE RSUs under the scheme after Resolution 5 passed will not participate until shareholder approval is obtained under that ASX Listing Rule. If Resolution 5 is not passed, the Company will not be able to proceed with the grant and will consider alternative incentives. A summary of the terms and conditions of the restated 2006 LTIP was included in the 2024 AGM Notice of Meeting. That document may be accessed from the Shareholders Meetings page on James Hardie's Investor Relations website (https://ir.jameshardie.com.au/financial-information/annual-reports-and-notice-of-meetings). Recommendation The Board believes it is in the interests of shareholders that the grant of fiscal year 2026 ROCE RSUs to the CEO up to the maximum number specified in Resolution 5 under the 2006 LTIP, subject to the above terms and conditions, is approved under and for the purposes of ASX Listing Rule 10.14 and unanimously recommends that you vote in favour of Resolution 5. Resolution 6 asks shareholders to approve, under the 2006 LTIP and for the purposes of ASX Listing Rule 10.14, the grant of Relative TSR RSUs to Aaron Erter, Director and CEO of James Hardie. Reasons for Relative TSR RSUs Relative TSR RSUs shall vest if James Hardie's TSR performance meets or exceeds the Relative TSR performance hurdles for fiscal year 2026 to fiscal year 2028 performance period. Upon vesting, Relative TSR RSUs shall be settled in either Shares listed and traded on the New York Stock Exchange or in CDIs on a 1-to-1 basis. Relative TSR RSU Changes for Fiscal Year 2026 The key aspects of the Relative TSR RSUs are unchanged from fiscal year 2025. Key Aspects of Relative TSR RSUs Grant: The CEO will receive a grant equal to the maximum number of Relative TSR RSUs (2.0x target). The number of Relative TSR RSUs which vest, and the number of Shares ultimately received depends on James Hardie's Relative TSR performance compared to the performance hurdles. RESOLUTION 6 - GRANT OF RELATIVE TOTAL SHAREHOLDER RETURN RESTRICTED STOCK UNITS TO CEO

------

![](ex9912jhx2025agmmaterial022.jpg)

21Notice of Annual General Meeting 2025 Performance Hurdle and Period: The performance hurdle vesting scale for the Relative TSR Grants is unchanged from fiscal year 2025 and is as follows: \*This reflects constituent companies making up the S&P 500 index as of date of grant Peer Group: The People & Remuneration Committee and the Board reviewed the appropriateness of the peer group used in prior years including fiscal year 2025 to fiscal year 2027 Relative TSR RSUs awards, and determined that due to the merger with The AZEK Company Inc., the composition of the current peer group would change in future and be less relevant over the next three years. Therefore, the Company's independent advisors, FW Cook and Guerdon Associates conducted a review of market practice in both Australia and the US. Based on market practice and the advisors' recommendation following the review, we changed our peer group for the Relative TSR RSUs to constituent companies making up the S&P 500 index as of date of grant which mitigates volatility in the measurement of results. Testing of Performance and Vesting: The performance hurdle will be tested (based on James Hardie's performance against the S&P 500 for the 20 trading days preceding the test date) and may vest after three years from 17 August 2025. Any Relative TSR RSUs that have not vested following this test will lapse. Maximum and Actual Number of Relative TSR RSUs The maximum number of Shares and Relative TSR RSUs for which approval is sought under this Resolution 6 is 370,000 and is based on the grant that would be made if James Hardie equals or exceeds the 80th percentile of performance against the S&P 500 and all the Relative TSR RSUs vest. The actual number of Relative TSR RSUs granted is determined by dividing the maximum dollar amount granted under the Relative TSR RSU portion of the LTI target (which is 2.0x LTI target) by the value of the Relative TSR RSUs, using a Monte Carlo simulation, over the 20 trading days preceding the date of grant, subject to the maximum number specified in the resolution. The method is consistent with the method of stock allocation of James Hardie's US competitors. Peer companies used to benchmark its executive compensation also use the same basis for compensation disclosures on which benchmarking is based. As with Resolution 5, in the unlikely event the grant calculation returns an actual number of Relative TSR RSUs to be granted that is greater than the maximum number of Shares for which approval is sought under this Resolution 6, James Hardie may grant a cash settled award equal in value to the number of Relative TSR RSUs which exceed the maximum number of Shares. Any such cash settled award made will vest on the same criteria as set forth above and would only vest in the event the Relative TSR RSU grant vests in full. Previous Grants For fiscal year 2026, as CEO of James Hardie, Aaron Erter is eligible to participate in the 2006 LTIP. The number of Relative TSR RSUs granted to Aaron Erter since joining James Hardie in September 2022, excluding the grants that are the subject of Resolution 6, is set out in the table below: PERFORMANCE AGAINST S&P 500 Index\* AMOUNT OF TARGET RELATIVE TSR RSUs TO VEST <40th Percentile 0.0 40th Percentile 0.5x >40th – <60th Percentile Sliding Scale 60th Percentile 1.0x >60th – <80th Percentile Sliding Scale ≥80th Percentile 2.0x DATE OF GRANT NUMBER GRANTED VESTING DATE 03 November 2022 38,387 17 August 2023 03 November 2022 39,450 17 August 2024 03 November 2022 115,688 17 August 2025 17 August 2023 137,718 17 August 2026 17 August 2024 137,865 17 August 2027

22Notice of Annual General Meeting 2025 There was no consideration paid by, and James Hardie did not provide loans to, the CEO in relation to the grant of these Relative TSR RSUs. General Relative TSR RSUs will be granted in accordance with the terms of the 2006 LTIP and on the basis set out in the Explanatory Notes. Currently, Aaron Erter is the only Director of James Hardie entitled to participate in the 2006 LTIP. Relative TSR RSUs will be granted for no consideration, and James Hardie will not provide loans to the CEO in relation to the grant of Relative TSR RSUs. Subject to the performance hurdles being met, the CEO will be entitled to receive Shares upon vesting of the Relative TSR RSUs for no consideration. Relative TSR RSUs will be granted to the CEO within 12 months of the passing of this Resolution 6. Summary of the Legal Requirements for Seeking Shareholder Approval The reason for seeking shareholder approval is the same as set out in the Explanatory Notes for Resolution 5. Resolution 6 seeks the required shareholder approval to approve the grant of Relative TSR RSUs under the 2006 LTIP and for the purposes of ASX Listing Rule 10.14.1 to James Hardie's CEO, Aaron Erter, for the fiscal year 2026 on the basis set out above. Aaron Erter's current total remuneration at the date of the Notice of Meeting is USD$8,694,400, including cash compensation of USD$2,594,400, long-term cash compensation of USD$2,033,333, and share-based compensation of USD$4,066,667. If Resolution 6 is passed, the Company will be able to proceed with the grant of Relative TSR RSUs under the 2006 LTIP to James Hardie's CEO, on the basis set out above. Details of any Relative TSR RSUs issued under the 2006 LTIP will be published in James Hardie's annual report relating to the period in which they are issued, along with a statement that approval for the issue was obtained under ASX Listing Rule 10.14. Any additional persons covered by ASX Listing Rule 10.14 who become entitled to participate in an issue of Relative TSR RSUs under the scheme after Resolution 6 passed will not participate until shareholder approval is obtained under that ASX Listing Rule. If Resolution 6 is not passed, the Company will not be able to proceed with the grant and will consider alternative incentives. Recommendation The Board believes it is in the interests of shareholders that the grant of Relative TSR RSUs to the CEO up to the maximum number specified in Resolution 6 under the 2006 LTIP, subject to the above terms and conditions, is approved under and for the purposes of ASX Listing Rule 10.14 and unanimously recommends that you vote in favour of Resolution 6. Resolution 7 asks shareholders to approve the issue of Shares (including, where relevant, underlying CDIs) for cash under the NED Equity Plan to Peter John Davis, Persio Lisboa, Anne Lloyd, Rada Rodriguez, Nigel Stein, Suzanne Rowland, Renee Peterson, John Pfeifer and, subject to their election as directors of the Company at this AGM, Gary Hendrickson, Jesse Singh and Howard Heckes for the next three years. At the November 2020 AGM, shareholders approved the NED Equity Plan and the issue of Shares for cash to participants to facilitate equity ownership for NEDs. Renewal of the NED Equity Plan and the issue of shares thereunder was subsequently reviewed at the August 2023 Annual General Meeting. Under the NED Equity Plan approved in 2020, the Administrator (being the Board or such committee(s) appointed by the Board from time to time) may invite "Eligible Participants" (NEDs or proposed non-executive directors or their nominees) to apply part or all of the cash component of their NED fees for services to the Board to acquire Shares, which include any applicable securities (Applicable Securities). In addition, having taken advice from the company's independent advisers, Guerdon and Associates and FW Cook, the People & Remuneration Committee and the Board determined that it was appropriate for a fixed portion of NED fees to be paid in Shares until such time as each NED has accumulated 1.5 times (and 2 times for the Chair) of their NED fee base in Shares, which includes any Shares represented by CDIs (Ownership Target). The portion is the same for each NED and is fixed for calendar year 2025. When a NED has met the Ownership Target, they may elect to continue to receive a fixed portion of their NED fees in Shares or alternatively receive all of their NED fees in cash. RESOLUTION 7 – THE ISSUE OF SECURITIES UNDER THE NED EQUITY PLAN

------

![](ex9912jhx2025agmmaterial024.jpg)

23Notice of Annual General Meeting 2025 Issue of Shares under the NED Equity Plan The number of Applicable Securities that an Eligible Participant will receive is calculated in accordance with the following formula (rounded down to the nearest whole number): [number of Applicable Securities = director fee amount for the relevant quarter / fair market value] The director fee amount will be the proportion of the NED fees that the Nominating and Governance Committee and the Board determine will be paid in Applicable Securities (Director Fee Amount). The Director Fee Amount will not exceed 50% of each NED's director's fee, and the proportion will be the same for each director. The fair market value will be based on the volume weighted average closing price for a CDI on the ASX (where an Eligible Participant will receive Applicable Securities in the form of CDIs) or Shares on the NYSE (where an Eligible Participant will receive Applicable Securities in the form of Shares), as the case may be, during a period of 5 trading days commencing on the first trading day following the announcement of the Company's quarterly results. A currency exchange calculation may also be required as NED fees are usually paid in USD$ and a CDI trade in AUD$. The Applicable Securities will be issued quarterly subject to compliance with James Hardie's Insider Trading Policy. On issue, the Applicable Securities will rank equally with the same class of Applicable Securities, and will carry the same dividend, voting and other rights. Eligible Participants will not have dividend or voting rights in respect of the Applicable Securities until such time as they are issued. Eligible Participants will have the right to elect to have Applicable Securities issued to them personally or to a nominee. The Applicable Securities issued to the Eligible Participants, or their nominee can be traded on the ASX, the NYSE or other applicable stock exchange, subject to insider trading laws and the James Hardie Insider Trading Policy. Other Issuances under the NED Equity Plan Under the NED Equity Plan, the Administrator may grant to NEDs or their nominee the right to acquire Applicable Securities (as described in this Explanatory Note to Resolution 7), share options (to subscribe for, acquire or be allocated Applicable Securities), restricted stock units (RSUs) (being an entitlement to acquire or be allocated Applicable Securities) and restricted shares (being an entitlement to Applicable Securities subject to satisfying vesting conditions as determined by the Administrator) (Awards) in the number and on terms and conditions (and to amend, modify, extend or renew Awards) in the Administrator's absolute discretion, subject to the listing rules of the ASX, the NYSE or other applicable stock exchange. The Administrator does not presently intend to issue share options, RSUs or restricted shares, and will not issue or agree to issue such securities without shareholder approval if such approval is required under the listing rules of the ASX, the NYSE or any other applicable stock exchange. The grant of the Awards and the terms and conditions of the grant will be detailed in the NED 's grant agreement. The NED Equity Plan also contains provisions in relation to the treatment of Awards on a change in control. In the event of a change in control, outstanding Awards will be subject to the definitive agreement entered into by James Hardie in connection with the change in control. Subject to applicable law and the ASX Listing Rules, the Board may determine to accelerate the vesting, exercisability or settlement of any Award, assume, substitute or convert any Award into a substantially equivalent award with respect to the acquiring or parent entity's securities, or cancel any Award in exchange for cash, securities or property. The NED Equity Plan provides that the Administrator may terminate the NED Equity Plan (or any part of it) at any time, provided all Awards made under the NED Equity Plan prior to such termination remain in effect until they have been satisfied or terminated in accordance with their terms and the NED Equity Plan. Summary of the Legal Requirements for Seeking Shareholder Approval ASX Listing Rule 10.14 (specifically ASX Listing Rules 10.14.1 and 10.14.2) provides that a listed company must not permit a NED or any associate of theirs to acquire equity securities or rights to be issued shares under an employee incentive scheme without the approval of its shareholders by way of ordinary resolution. This Resolution 7 seeks the required approval for the issue of Shares to Peter John Davis, Persio Lisboa, Anne Lloyd, Rada Rodriguez, Nigel Stein, Suzanne Rowland, Renee Peterson, John Pfeifer, Gary Hendrickson, Howard Heckes and Jesse Singh under and for the purposes of ASX Listing Rule 10.14. If shareholders do not approve the issue of securities under the NED Equity Plan to Peter John Davis, Persio Lisboa, Anne Lloyd, Rada Rodriguez, Nigel Stein, Suzanne Rowland, Renee Peterson, John Pfeifer, Gary Hendrickson, Howard Heckes and Jesse Singh, James Hardie shall not issue or agree to issue any securities to that NED under the NED Equity Plan, and that those NEDs will receive all their fees in cash. Shareholder approval is sought for the issue of Shares to Persio Lisboa, Nigel Stein, Suzanne Rowland, Renee Peterson, John Pfeifer, and, subject to their re-election as directors of the Company at this AGM, Peter John Davis, Anne Lloyd, Rada Rodriguez and, subject to their election as directors of the Company at this AGM, Gary Hendrickson, Howard Heckes and Jesse Singh under the NED Equity Plan for the purposes of ASX Listing Rules 10.14.

27Notice of Annual General Meeting 2025 In addition, under certain of the Company's remuneration policies, NEDs who are resident outside of Ireland may receive supplemental compensation depending on their country of residence. Further details of such supplemental payments are set out in the Company's 2025 Annual Report. The Board considers that these fees, together with the supplemental compensation paid under the Company's remuneration policies, provide an appropriate level of reward to attract and retain appropriately qualified NEDs. Fees, set with reference to relevant peer benchmarks, reflect the Board's desired diversity for NEDs from the USA, Europe and Australia given the Company's geographic spread, and to reflect the required time commitment, particularly in view of the additional complexity of the Company's now expanded business. The fee pool is also intended to provide the Board with sufficient flexibility to recruit and retain additional directors, as part of the Board's long-term succession plan. In that regard, the number of NEDs has increased from nine to eleven, which is the current maximum permitted under the Company's Articles of Association. This increase reflects the Company's ongoing succession planning, including through the recent AZEK acquisition. The Company forecasts that in fiscal year 2026, the aggregate amount of annual fees and supplemental compensation to be paid will be approximately US$4,370,060. The Board considers it prudent to seek approval to increase the maximum at this time in order to ensure the Company is able to appropriately remunerate the increased Board, while maintaining flexibility for future succession planning and Board composition needs, should circumstances change. If Resolution 8 is passed, the maximum aggregate amount of fees that may be paid to all of the Company's NEDs will be US$4,800,000 per annum. This does not mean that the Company must utilise the entire maximum amount approved for NEDs' fees each year. If Resolution 8 is not passed, the Company will not be permitted to pay fees to its NEDs which exceed the aggregate amount of directors' fees already approved by the Company's shareholders. Recommendation As the directors have a personal interest in Resolution 8, they make no recommendation on whether shareholders should vote in favour of the resolution. Shareholders should judge for themselves whether to approve an increase to the maximum aggregate remuneration payable annually to NEDs under ASX Listing Rule 10.17 and Article 98(b) of the Company's Articles of Association.

This may be done by specifying the number of shares underlying your CDI holding or the percentages of that holding. If you vote in excess of 100% of your holding for the resolution, your vote on the resolution will be invalid. If you mark more than one box for the resolution, except to show a portion in the manner discussed above, your vote on that resolution will be invalid.
