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 media releases and other written materials and in oral statements made by the Company’s officers, directors or employees to analysts, institutional investors, representatives of the media and others. 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. These forward-looking statements are based upon management's current expectations, estimates, assumptions, beliefs and general good faith evaluation of information available at the time the forward-looking statements were made concerning future events and conditions. Readers are cautioned not to place undue reliance on any forward-looking statements or rely upon them as a guarantee of future performance or results or as an accurate indication of the times at or by which any such performance or results will be achieved. Forward-looking statements are necessarily subject to risks, uncertainties and other factors, many of which are unforeseeable and beyond the Company’s control. Many factors could cause actual results, performance or achievements to be materially different from those expressed or implied in this Earnings Presentation, including, among others, the risks and uncertainties set forth in Section 3 “Risk Factors” in James Hardie’s Annual Report on Form 20-F for the year ended March 31, 2025, which include, but are not necessarily limited to risks such as changes in general economic, political, governmental and business conditions globally and in the countries in which the Company does business; changes in interest rates; changes in inflation rates; changes in exchange rates; the level of construction generally; changes in cement demand and prices; changes in raw material and energy prices; changes in business strategy; the AZEK integration and anticipated benefits and various other factors. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described herein. James Hardie assumes no obligation to update or correct the information contained in this Earnings Presentation except as required by law. This Earnings Presentation includes financial measures that are not considered a measure of financial performance under generally accepted accounting principles in the United States (GAAP). These financial measures are designed to provide investors with an alternative method for assessing our performance from on-going operations, capital efficiency and profit generation. Management uses these financial measures for the same purposes. These financial measures are or may be non-GAAP financial measures as defined in the rules of the U.S. Securities and Exchange Commission and may exclude or include amounts that are included or excluded, as applicable, in the calculation of the most directly comparable financial measures calculated in accordance with GAAP. These non-GAAP financial measures should not be considered to be more meaningful than the equivalent GAAP measure. Management has included such measures to provide investors with an alternative method for assessing its operating results in a manner that is focused on the performance of its ongoing operations and excludes the impact of certain legacy items, such as asbestos adjustments, or significant non-recurring items, such as asset impairments, restructuring expenses, acquisition and pre-close financing related costs, as well as adjustments to tax expense. Additionally, management uses such non-GAAP financial measures for the same purposes. However, these non-GAAP financial measures are not prepared in accordance with GAAP, may not be reported by all of the Company’s competitors and may not be directly comparable to similarly titled measures of the Company’s competitors due to potential differences in the exact method of calculation. For additional information regarding the non-GAAP financial measures presented in this Earnings Presentation, including a reconciliation of each non-GAAP financial measure to the equivalent GAAP measure, see slides titled “Non-GAAP Financial Measures” included in this Earnings Presentation. This Earnings Presentation forms part of a package of information about the Company’s results. It should be read in conjunction with the other parts of this package, including the Management’s Analysis of Results, Condensed Consolidated Financial Statements and Earnings Release. All comparisons made are vs. the comparable period in the prior fiscal year and amounts presented are in US dollars, unless otherwise noted.

We have not reconciled Adjusted EBITDA and Free Cash Flow guidance to the most comparable GAAP measures as a result of uncertainty regarding, and the potential variability of, reconciling items. Such reconciling items that impact Adjusted EBITDA and Free Cash Flow have not occurred, are outside of our control and cannot be reasonably predicted. Accordingly, a reconciliation of each of Adjusted EBITDA and Free Cash Flow to its most comparable GAAP measure is not available without unreasonable effort. However, it is important to note that material changes to these reconciling items could have a significant impact on our Adjusted EBITDA and Free Cash Flow guidance and future GAAP results.
