Exhibit 99.2

James Hardie Reports Third Quarter FY26 Results

Q3 FY26 Net Sales of $1.2 Billion, Up +30% with Organic Net Sales +1%

Operating Income of $176 Million, Adjusted EBITDA of $330 Million

Siding & Trim Net Sales Up +10% with Organic Net Sales Down (2%)

~500 Basis Points of Sequential Siding & Trim Adjusted EBITDA Margin Expansion

Deck, Rail & Accessories Net Sales Up +2% with Sell-Through Up Mid-Single-Digits 1

Integration and Cost Synergies Ahead of Schedule, Focused on the Achievement of $125 Million Target

James Hardie Industries plc (NYSE / ASX : JHX) ("James Hardie" or the "Company"), a leading provider of exterior home and outdoor living solutions, today announced results for its third quarter ending December 31, 2025.

Aaron Erter, CEO of James Hardie said, “In the third-quarter, we achieved or exceeded each of our financial commitments despite a mixed macro backdrop. We are taking actions to address the current market environment, including optimizing our manufacturing footprint and better aligning our cost structure with the slower, but stabilizing, pace of demand. These actions will improve near-term profitability and better position the Company to profitably grow when conditions improve.

Siding & Trim organic net sales were down modestly in the quarter, while Adjusted EBITDA margin improved nearly 500 basis points sequentially primarily driven by price / mix favorability and our actions to drive Hardie Operating System savings. Deck, Rail & Accessories delivered mid-single-digit sell-through growth, demonstrating our ability to drive material conversion through channel expansion and new product initiatives."

Mr. Erter continued, “Our confidence in the combination of James Hardie and AZEK continues to be strong as customers respond to our differentiated products, leading brands, focus on innovation and investment across the value chain. We continue to make progress on the integration and have surpassed our FY26 cost synergy goal. Our progress to date reaffirms our confidence in hitting our $125 million cost synergy target. On the commercial front, our early wins with dealers, contractors and homebuilders will drive meaningful revenue synergies in FY27 and beyond, demonstrating our potential to accelerate material conversion across exteriors and outdoor living."

Note:1All Deck, Rail & Accessories growth comparisons correspond to the quarter ended December 31, 2024, prior to the acquisition of AZEK by James Hardie, unless otherwise stated.

Siding & Trim

	Q3 FY26	Q3 FY25		Change	9 Months<br>FY26		9 Months<br>FY25		Change
Siding & Trim	(US millions)
Net Sales	788.3	719.3		+10%	2,196.1		2,144.4		2%
Operating Income	202.9	209.3		(3%)	515.1		638.5		(19%)
Operating Income Margin	25.7	29.1	%	(340bps)	23.5	%	29.8	%	(630bps)
Adjusted EBITDA	268.6	250.5		+7%	698.4		754.0		(7%)
Adjusted EBITDA Margin	34.1	34.8	%	(70bps)	31.8	%	35.2	%	(340bps)

All values are in US Dollars.

Net sales increased 10% due to the inorganic net sales contribution from AZEK Exteriors. On an organic basis, net sales declined (2%) with an increase in average net sales price more than offset by lower volumes driven by soft market demand. Volume of Exterior products declined mid-single-digits, with Single-Family down high-single-digits and Multi-Family up high-single-digits, while volume of Interior products declined double-digits. The Single-Family Exteriors decline was primarily due to a weaker new construction environment across the South, where James Hardie has built strong leadership positions with large homebuilders in key long-term growth markets such as Texas, Florida and Georgia. Housing markets in these geographies have been especially impacted by affordability challenges and elevated housing inventory. While Adjusted EBITDA margin improved 490bps sequentially, adjusted EBITDA margin decreased (70bps) year-over-year to 34.1%, due to unfavorable production cost absorption and higher freight and raw material costs, and the allocation of certain R&D expenses which were not allocated to the segment in the prior year, partially offset by a higher average net sales price and Hardie Operating System (HOS) savings.

In Siding & Trim, we are focused on returning the segment to organic growth through four core growth strategies.

i.R&R Focus: We are increasing our focus on repair & remodel, particularly in the Northeast and Midwest, where we see $1 billion material conversion opportunity in wood- and wood-look siding products

ii.Deeper New Construction Penetration: We are expanding on our strong large builder relationships and seeking growth with custom and local builders where there is $750 million of opportunity for additional growth

iii.Product Innovation: We are focused on new product innovation in Siding, including differentiated offerings, to support our long-term growth

iv.Installation Efficiency: We are partnering with our contractors and installers to introduce innovative installation techniques to reduce time and installed costs, expanding the total addressable market for fiber cement

Deck, Rail & Accessories (DR&A)

	Q3 FY26	9 Months<br>FY26
Deck, Rail & Accessories	(US millions)
Net Sales	194.1	449.9
Operating Loss	(24.0)	(35.9)
Operating Loss Margin	(12.4	(8.0	%)
Adjusted EBITDA	48.7	127.3
Adjusted EBITDA Margin	25.1	28.3	%

All values are in US Dollars.

Deck, Rail & Accessories net sales increased +2% compared to the quarter ended December 31, 2024 prior to the acquisition driven primarily by price / mix. Sell-through was up mid-single-digits, consistent with growth in the prior quarter. Adjusted EBITDA margin was 25.1% reflecting the benefit of top-line growth, partially offset by growth investments. In addition to cost synergies, the runway for margin improvement in Deck, Rail & Accessories is enabled by recycling initiatives, improved absorption across the manufacturing network, and leveraging the Hardie Operating System.

In Deck, Rail & Accessories, the organic strategy remains consistent with a focus on continued channel expansion and new product launches. Last calendar year's new product launches have been well received by customers, and additional new offerings are being launched in early 2026 which strengthen TimberTech's commitment to combining superior aesthetics with advanced functionality for both homeowners and contractors alike. Additionally, the combination with James Hardie has helped to accelerate growth and secure incremental shelf space at dealer partners throughout early buy negotiations as customers recognize the enhanced value proposition delivered through a comprehensive product portfolio, trusted brands and long-term partnerships.

Australia & New Zealand (ANZ)

	Q3 FY26	Q3 FY25		Change	9 Months<br>FY26		9 Months<br>FY25		Change
Australia & New Zealand	(US millions, unless otherwise noted)
Net Sales	126.5	118.1		+7%	381.0		401.8		(5%)
Net Sales (A$ millions)	192.9	180.1		+7%	585.6		606.9		(4%)
Operating Income	35.6	34.8		+2%	111.4		68.0		+64%
Operating Income Margin	28.1	29.3	%	(120bps)	29.2	%	17.2	%	+1,200bps
Adjusted EBITDA	41.2	39.7		+4%	127.7		139.7		(9%)
Adjusted EBITDA Margin	32.6	33.5	%	(90bps)	33.5	%	34.7	%	(120bps)

All values are in US Dollars.

Net sales increased +7%, with low-single-digit volume growth and a mid-single-digit increase in average net sales price. Adjusted EBITDA margin of 32.6% decreased (90bps) as volume and price growth and HOS savings were more than offset by unfavorable production cost absorption and the allocation of R&D costs which were not previously allocated to the reportable segments.

The Company is focused on driving growth in Australia and New Zealand through new customer acquisitions and project conversion enabled by customer collaboration and leveraging the James Hardie brand. The teams are innovating to accelerate material conversion to fiber cement with a key focus on new construction. Overall, while market demand remains challenged, the ANZ team is focused on finding further manufacturing efficiencies and driving HOS savings to underpin the segment's consistent profitability.

Europe

	Q3 FY26	Q3 FY25		Change	9 Months<br>FY26		9 Months<br>FY25		Change
Europe	(US millions, unless otherwise noted)
Net Sales	130.9	115.9		+13%	404.9		359.8		+13%
Net Sales (€ millions)	112.4	108.6		+3%	350.4		332.9		+5%
Operating Income	9.1	3.6		+153%	37.9		24.7		+53%
Operating Income Margin	7.0	3.1	%	+390bps	9.4	%	6.8	%	+260bps
EBITDA	16.6	11.9		+39%	59.5		48.6		+22%
EBITDA Margin	12.7	10.3	%	+240bps	14.7%		13.5%		+120bps

All values are in US Dollars.

Net sales increased +13%, or +3% in Euros, driven by mid-single-digit volume growth. While underlying price realization remains positive, average net sales price in Euros was down modestly due to unfavorable mix shift as fiber gypsum volumes meaningfully outpaced fiber cement in the quarter. EBITDA margin increased +240bps to 12.7%, attributable to favorable plant performance, as well as lower raw material costs. Higher SG&A expense relates to increased investment in sales teams and marketing supporting growth strategies for high-value products.

Markets across Europe remain challenged, particularly in Germany, the Company's largest European market, where improvement is anticipated to be more gradual. Growth in high-value products, such as Therm25TM fiber gypsum flooring, remains a strategic priority, as leveraging a broader and deeper product portfolio should accelerate share gains and customer wins. The team's plan to expand margins is comprised of purposeful investment to drive operating leverage alongside sales growth and HOS savings from production footprint optimization and freight management.

Outlook

FY26 Guidance

With respect to FY26 guidance, Ryan Lada, CFO, said, “For Siding & Trim, market conditions remain challenged, consistent with our prior expectations; however, channel inventories have normalized. As a result, we are allowing our stronger-than-expected third-quarter performance to flow through to full-year results, resulting in a modest increase in the guidance range for the segment. We continue to expect the broader Exteriors market to remain mixed in the near term. For Deck, Rail & Accessories, mid-single-digit sell-through growth continued through the third quarter and into early Q4. We expect channel partner inventories to remain at seasonally normal levels for the remainder of the fiscal year."

•Net Sales for Siding & Trim: $2.953 to $2.998 billion (prev. $2.925 to $2.995 billion)

•Net Sales for Deck, Rail & Accessories: $787 to $800 million (prev. $780 to $800 million)

•Adjusted EBITDA for Siding & Trim: $939 to $962 million (prev. $920 to $955 million)

•Adjusted EBITDA for Deck, Rail & Accessories: $219 to $224 million (prev. $215 to $225 million)

•Total Adjusted EBITDA: $1.232 to $1.263 billion (prev. $1.20 to $1.25 billion)

•Free Cash Flow: At Least $200 million (unchanged)

Note: All guidance includes a partial-year contribution from the AZEK acquisition which was incorporated into James Hardie results beginning at closing on July 1, 2025. Free cash flow represents net cash provided by operating activities less purchases of property, plant and equipment net of proceeds from the sale of property, plant and equipment.

Cash Flow, Capital Investment & Allocation
---

Operating cash flow totaled $455 million for the nine months ended FY26, driven by net income, adjusted for non-cash items of $536 million and lower working capital of $33 million, partially offset by $87 million of asbestos claims and handling costs paid. Capital expenditures were $303 million.

Our capital expenditures program is driven by strategic investments that support long‑term growth and operational excellence. These priorities include adding new capacity ahead of anticipated demand, funding new product development and other strategic initiatives, and maintaining and reinvesting in our existing facilities and equipment. For fiscal year 2026, we expect total capital expenditures of approximately $400 million, inclusive of approximately $75 million related to AZEK initiatives. Spending associated with our Global Capacity Expansion program is projected to be approximately $90 million of the fiscal year 2026 total.

Cautionary Note and Use of Non-GAAP Measures
---

This Earnings Release includes financial measures that are not considered a measure of financial performance under generally accepted accounting principles in the United States (GAAP), such as Adjusted Net Income, Adjusted EBITDA, Adjusted Diluted EPS and Free Cash Flow. 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 gain or 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. A reconciliation of these adjustments to the most directly comparable GAAP measure is included in this Earnings Release below.

The Company is unable to forecast the comparable US GAAP financial measure for future periods due to, amongst other factors, uncertainty regarding the impact of actuarial estimates on asbestos-related assets and liabilities in future periods.

This Earnings Release contains forward-looking statements and information that are subject to risks, uncertainties and assumptions. Many factors could cause the actual results, performance or achievements of James Hardie to be materially different from those expressed or implied in this release, 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 fiscal year ended March 31, 2025; changes in general economic, political, governmental and business conditions globally and in the countries in which James Hardie 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 acquisition 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 Release except as required by law.

This Earnings Release has been authorized by the James Hardie Board of Directors.

Exhibit 99.3

Management’s Analysis of Results

This Management’s Analysis of Results forms part of a package of information about James Hardie Industries plc’s results. It should be read in conjunction with the other parts of this package, including the Earnings Release, the Earnings Presentation and the Condensed Consolidated Financial Statements. Except as otherwise indicated in this Management’s Analysis of Results, James Hardie Industries plc is referred to as “JHI plc.” JHI plc, together with its direct and indirect wholly-owned subsidiaries, are collectively referred to as “James Hardie", the “Company”, “we”, “our”, or “us". Definitions for certain capitalized terms used in this Management’s Analysis of Results can be found in the section titled “Non-GAAP Financial Measures".

This Management’s Analysis of Results includes financial measures that are not considered a measure of financial performance under generally accepted accounting principles in the United States (“GAAP”). These non-GAAP financial measures should not be considered to be more meaningful than the equivalent GAAP measures. Management has included such measures to provide investors with an alternative method for assessing the Company's financial condition and operating results in a manner that is focused on the performance of its ongoing operations. These measures exclude the impact of certain legacy items, such as asbestos adjustments, or significant non-recurring items, such as asset impairments, restructuring gain or expenses, acquisition and pre-close financing related costs, as well as adjustments to tax expense. In addition, management provides an adjusted effective tax rate, which excludes the tax impact of the special pre-tax items (items listed above) and special tax items. Management believes that this non-GAAP tax measure provides an ongoing effective rate which investors may find useful for historical comparisons and for forecasting and is an alternative method of assessing the economic impact of taxes on the Company, as it more closely approximates payments to taxing authorities. Management uses such non-GAAP financial measures for the same purposes. These non-GAAP measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. 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 Management’s Analysis of Results, including a reconciliation of each non-GAAP financial measure to the equivalent GAAP measure, see the section titled “Non-GAAP Financial Measures".

James Hardie Industries plc is a leading provider of exterior home and outdoor living solutions. On 1 July 2025, we completed the acquisition of The AZEK Company Inc. ("AZEK"), an industry-leading designer and manufacturer of low maintenance and environmentally sustainable outdoor living products, which has manufacturing and recycling facilities in the United States. The results below are based on preliminary purchase price calculations and allocations, and these estimates and assumptions are subject to change as additional information is obtained during the measurement period, which may be up to one year from the acquisition date.

Income tax expense		41.9		60.6		(31%)
Net income		68.7		141.7		(52%)

•Net sales increased 30% primarily due to the AZEK acquisition, which accounted for US$275.0 million of the increase, along with higher net sales in the Europe and Australia & New Zealand segments. This was partially offset by lower net sales in our North America fiber cement business.

•Gross margin decreased 1.8 percentage points primarily due to the amortization of certain intangible assets resulting from the AZEK acquisition of US$12.2 million and lower gross margin in our North America fiber cement business.

•Restructuring, net includes a US$26.2 million gain on the sale of land as a result of our strategic decision to cancel the Truganina greenfield project as mentioned in fiscal year 2024. Included in FY24 was a US$20.1 million impairment on this property, based on the information available at that time.

•Operating income margin decreased 7.4 percentage points, driven by AZEK acquisition related expenses of US$29.4 million, lower gross margin and higher SG&A expenses as a percentage of sales largely driven by the amortization of certain intangible assets resulting from the AZEK acquisition recorded in SG&A of US$45.4 million. This decrease was partially offset by the gain on sale of land as mentioned above.

•Interest, net increased US$61.8 million driven by a higher principal balance outstanding related to our US$2.5 billion senior secured credit facilities (the "Credit Facilities") and US$1.7 billion senior secured notes (the "Notes").

•Net income decreased US$73.0 million due to lower operating income and higher interest expense attributable to the factors described above, partially offset by lower income tax expense.

•Net sales increased 18% primarily due to the AZEK acquisition, which contributed net sales of US$620.1 million, as well as higher net sales in Europe. This was partially offset by lower net sales in our legacy North America fiber cement business and Australia & New Zealand segment.

•Gross margin decreased 3.9 percentage points mainly driven by a US$47.9 million inventory step-up adjustment related to recording the acquired inventory of AZEK at fair value, which was fully recognized during the year, and amortization of certain intangible assets resulting from the AZEK acquisition of US$24.6 million, as well as lower gross margin in the North America fiber cement business.

•Operating income margin decreased 10.5 percentage points to 9.9%, driven by AZEK acquisition related expenses of US$189.1 million, lower gross margin and higher SG&A expenses as a percentage of sales largely driven by the amortization of certain intangible assets resulting from the AZEK acquisition recorded in SG&A of US$81.7 million. This decrease was partially offset by the US$26.2 million gain related to the land sale discussed above and restructuring expenses of US$57.3 million in the prior year related to the closure of our Philippines manufacturing and commercial operations.

•Interest, net increased US$161.4 million driven by a higher principal balance outstanding related to our new Credit Facilities and Notes, and pre-close financing and interest costs of US$34.9 million.

•Net income decreased US$304.9 million due to lower operating income and higher interest expense attributable to the factors described above, as well as an US$11.6 million non-cash loss on our interest rate swap incurred in the first quarter of fiscal year 2026. This was partially offset by lower income tax expense.

Q3 FY26 vs Q3 FY25

Net sales increased 10% driven by sales of US$80.9 million associated with the acquired AZEK Exteriors business, which were in line with AZEK's net sales for the quarter ended 31 December 2024 prior to the acquisition. Net sales in our North America fiber cement business decreased 2% primarily due to market weakness, partially offset by a higher average net sales price primarily resulting from our annual price increase.

Gross margin decreased 0.5 percentage points driven by our North America fiber cement business which had unfavorable production cost absorption and higher freight and raw material costs, partially offset by a higher average net sales price and US$4.7 million of startup costs at our Prattville facility in the prior corresponding period. In addition, gross margin was unfavorably impacted by the amortization of certain intangible assets resulting from the AZEK acquisition of US$1.2 million.

| Management's Analysis of Results: James Hardie - 3rd Quarter Fiscal Year 2026 | 4 | | --- | --- || OPERATING RESULTS | | --- |

SG&A expenses increased 23%, and as a percentage of sales, SG&A increased 1.2 percentage points. This increase was driven by AZEK, including the amortization of certain intangible assets resulting from the AZEK acquisition of US$11.6 million, and employee and marketing costs. This was partly offset by lower SG&A expenses in our North America fiber cement business mainly due to lower marketing expenses.

R&D expenses increased US$9.5 million primarily due to the allocation of certain R&D expenses which were not allocated to our segments prior to the second quarter of fiscal year 2026.

Operating income margin decreased 3.4 percentage points to 25.7%, primarily driven by lower gross margin and higher SG&A and R&D expenses.

Nine Months FY26 vs Nine Months FY25

Net sales increased 2% driven by sales of US$170.2 million associated with the newly acquired AZEK business. North America fiber cement sales declined 6% primarily due to market weakness, partially offset by a higher average net sales price primarily resulting from our annual price increase.

Gross margin decreased 3.2 percentage points driven by our North America fiber cement business primarily due to unfavorable production cost absorption and higher pulp and other raw material costs. This was partially offset by a higher average net sales price and US$12.1 million of startup costs at our Prattville and Westfield facilities in the prior corresponding period. In addition, gross margin was unfavorably impacted by the inventory step-up adjustment of US$11.2 million which was fully recognized during the year, as well as the amortization of certain intangible assets resulting from the AZEK acquisition of US$2.8 million.

SG&A expenses increased 22%, and as a percentage of sales, SG&A expenses increased 2.0 percentage points. This increase was primarily driven by AZEK, including the amortization of certain intangible assets resulting from the AZEK acquisition of US$20.8 million, and higher employee and marketing costs.

R&D expenses increased US$17.4 million primarily due to the allocation of certain R&D expenses which were not allocated to our segments prior to the second quarter of fiscal year 2026.

Operating income margin decreased 6.3 percentage points to 23.5%, primarily driven by lower gross margin and higher SG&A and R&D expenses.

Q3 FY26 vs Q3 FY25(A$)

Net sales increased 7%, primarily driven by a higher average net sales price attributable to our price increase and favorable product mix, and volume growth in Australia and New Zealand.

Gross margin decreased 0.9 percentage points primarily due to unfavorable production cost absorption, partially offset by a higher average net sales price.

SG&A expenses increased 1% primarily due to higher employee costs, partially offset by the closure of our Philippines operations. As a percentage of sales, SG&A expenses decreased 0.6 percentage points.

R&D expenses increased A$1.9 million primarily due to the allocation of certain R&D expenses which were previously unallocated to our segments prior to the second quarter of fiscal year 2026.

Lower operating income margin resulted primarily from lower gross margin and higher R&D expenses.

Nine Months FY26 vs Nine Months FY25 (A$)

Net sales decreased 4%, driven by lower volumes of 16%, partially offset by a higher average net sales price. The decline in volumes and higher price were primarily attributable to the closure of our Philippines manufacturing and commercial operations. Net sales from the Philippines for the nine months ended December 2024 was A$39.2 million.

Gross margin increased 0.2 percentage points primarily due to a higher average net sales price and geographic mix, partially offset by unfavorable plant performance.

SG&A expenses increased 10% primarily due to recording a lease exit cost, as well as higher marketing and employee costs, partially offset by the closure of our Philippines operations. As a percentage of sales, SG&A expenses increased 1.5 percentage points.

R&D expenses increased A$3.7 million primarily due to the allocation of certain R&D expenses which were previously unallocated to our segments prior to the second quarter of fiscal year 2026.

Higher operating income margin resulted primarily from the absence of restructuring expenses in the current year and higher gross margin, partially offset by higher SG&A and R&D expenses. Prior year included restructuring expenses of A$84.7 million related to the closure of our Philippines manufacturing and commercial operations.

General Corporate and Unallocated R&D costs for the three and nine month periods of US$47.4 million and US$289.7 million, respectively, includes acquisition related expenses of US$25.8 million and US$180.7 million, respectively. These costs primarily relate to professional service fees, severance and retention costs and the acceleration of certain stock awards associated with the AZEK acquisition. This was partially offset by a US$26.2 million gain on the sale of land in Q3 FY26 as a result of our strategic decision to cancel the Truganina greenfield project, as mentioned in fiscal year 2024.

For the three month period, Adjusted General Corporate and Unallocated R&D costs increased US$6.4 million mainly due to AZEK expenses related to stock compensation, employee costs and professional fees, as well as higher legacy Corporate costs which were driven by higher stock compensation expense, employee costs and professional fees. These costs were partially offset by the allocation of previously unallocated R&D costs to our segments beginning 1 July 2025.

For the nine month period, Adjusted General Corporate and Unallocated R&D costs decreased US$1.9 million mainly due to the allocation of R&D costs noted above. In addition, lower legacy Corporate costs, driven mainly by lower employee and legal costs, were more than offset by AZEK expenses related to stock compensation, employee costs and professional fees.

All values are in US Dollars.

The effective tax rate increased 7.9 percentage points and 17.7 percentage points for the three and nine month periods, respectively, due to the reduction in net income compared to the previous corresponding periods. The discrete items related to the ATO settlement agreement and AZEK acquisition costs recognized in Q2 FY26 also drove the increase in the nine month effective tax rate.

The adjusted effective tax rate decreased 6.1 percentage points and 4.7 percentage points for the three and nine month periods, respectively, primarily due to a change in geographical mix of taxable earnings, including the effects of the increase in debt in our US subsidiaries.

Capital Expenditures

Our capital expenditures program is driven by strategic investments that support long‑term growth and operational excellence. These priorities include adding new capacity ahead of anticipated demand, funding new product development and other strategic initiatives, and maintaining and reinvesting in our existing facilities and equipment.

For fiscal year 2026, we expect total capital expenditures of approximately US$400 million, inclusive of approximately US$75 million related to AZEK initiatives. Spending associated with our Global Capacity Expansion program is projected to be approximately US$90 million of the fiscal year 2026 total.

During fiscal year 2026, we will contribute A$193.6 million to AICF, excluding interest, in quarterly installments. The first three payments of A$48.4 million were made 1 July 2025, 1 October 2025 and 2 January 2026.

Based on our existing cash balances, together with anticipated operating cash flows and unutilized credit facilities, we anticipate we will have sufficient funds to meet our planned working capital and other expected cash requirements for the next twelve months.

Capital Allocation

Our Capital Allocation framework prioritizes the use of free cash flow as follows:

•Invest in organic growth

•Reduce balance sheet leverage in line with our stated commitments

•Return capital to shareholders

•Evaluate tuck-in opportunities to bolster capabilities in railing & recycling

2 Q3 FY26 EARNINGS PRESENTATION Cautionary Note and Use of Non-GAAP Measures This Earnings Presentation contains forward looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. 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 gain or 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.

Notes to Condensed Consolidated Financial Statements

1.  Organization and Significant Accounting Policies

Nature of Operations

James Hardie Industries plc ("JHI plc") and its direct and indirect wholly-owned subsidiaries and variable interest entity ("VIE") are collectively referred to as "James Hardie", the "James Hardie Group" or the "Company". The Company manufactures and sells fiber cement, fiber gypsum and cement-bonded building products for interior and exterior building construction applications, primarily in the United States, Australia, Europe and New Zealand. In August 2024, the company ceased manufacturing in the Philippines.

On 1 July 2025, the Company completed its acquisition of The AZEK Company Inc. ("AZEK"), an industry-leading designer and manufacturer of low maintenance and environmentally sustainable outdoor living products, with manufacturing and recycling facilities in the United States.

Basis of Presentation

The Company operates on a fiscal year ending 31 March. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the U.S. generally accepted accounting principles ("GAAP") for interim financial information, and in management's opinion, includes all adjustments, consisting of only normal and recurring adjustments, necessary for the fair statement of the Company's financial position, results of operations and cash flows for the interim periods presented. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. Interim financial results are not necessarily indicative of results anticipated for the full fiscal year or any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto, included in the Company’s Annual Report on Form 20-F for the fiscal year ended 31 March 2025 from which the prior year balance sheet information herein was derived. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expense, and related disclosures. Actual results could differ from those estimates. Certain prior period amounts have been reclassified to conform to the current period presentation.

The Company has recorded on its condensed consolidated balance sheets certain foreign assets and liabilities, that are denominated in foreign currencies and subject to translation or remeasurement into US dollars at each reporting date under the applicable accounting guidance. Unless otherwise noted, the Company converts foreign currency denominated assets and liabilities into US dollars at the spot rate at the end of the reporting period; while revenues and expenses are converted using an average exchange rate for the period.

The gains and losses on the remeasurement of the Company’s Euro denominated debt are economically offset by foreign exchange gains and losses on loans between subsidiaries, resulting in a net immaterial translation gain or loss which is recorded in the Selling, general and administrative expenses in the condensed consolidated statements of operations and comprehensive income.

Summary of Significant Accounting Policies

During the nine months ended 31 December 2025, the Company entered into an interest rate swap to manage market risks and reduce exposure resulting from fluctuations in interest rates associated with the new senior secured term facilities by converting a portion of its floating rate debt to fixed rate debt. The Company recognizes all derivative instruments at fair value and classifies them on the condensed consolidated balance sheet as either Other non-current assets or Other current liabilities. The Company

F-8

James Hardie Industries plc

Notes to Condensed Consolidated Financial Statements (continued)

estimates the fair value of the interest rate swap using a valuation model based on observable market data, such as yield curves, and as such are classified as Level 2 within the fair value hierarchy. The interest rate swap qualified and was designated as a cash flow hedge on 1 July 2025. The effective portion of the change in fair value of the derivative is recorded as part of Accumulated other comprehensive loss and then reclassified into Interest, net in the same period in which the hedged transaction affects earnings. The related gains and losses are included as a reconciling item in the reconciliation of net income and net cash flow from operating activities each reporting period. The Company does not use derivatives for trading purposes. Refer to Note 9 "Derivative Instruments" for further details on the Company's derivative instrument.

Other than noted above, there were no changes to our significant accounting policies as described in our Annual Report on Form 20-F for the fiscal year ended 31 March 2025.

Cash and Cash Equivalents, Restricted Cash and Restricted Cash - Asbestos

The following table provides a reconciliation of Cash and cash equivalents, Restricted cash and Restricted cash - Asbestos reported within the condensed consolidated balance sheets that sum to the total of the same such amounts shown in the condensed consolidated statements of cash flows:

	31 December		31 March
(Millions of US dollars)	2025		2025
Cash and cash equivalents	$	344.2	$	562.7
Restricted cash	5.0		5.0
Restricted cash - Asbestos	25.7		37.9
Total	$	374.9	$	605.6

Restricted cash relates to letters of credit with insurance companies, which restrict the cash from use for general corporate purposes.

Restricted cash - Asbestos is restricted to the settlement of asbestos claims and for the payment of the operating costs of Asbestos Injuries Compensation Fund ("AICF").

Earnings Per Share

Basic earnings per share ("EPS") is calculated using net income divided by the weighted average number of common shares outstanding during the period. Diluted EPS is similar to basic EPS except that the weighted average number of common shares outstanding is increased to include the number of additional common shares calculated using the treasury method that would have been outstanding if the dilutive potential common shares, such as stock options and restricted stock units, had been issued.

Basic and diluted common shares outstanding used in determining net income per share are as follows:

	Three Months<br>Ended 31 December		Nine Months<br>Ended 31 December
(Millions of shares)	2025	2024	2025	2024
Basic common shares outstanding	579.4	429.5	529.2	431.2
Dilutive effect of stock awards	3.7	1.4	4.7	1.4
Diluted common shares outstanding	583.1	430.9	533.9	432.6

James Hardie Industries plc

Notes to Condensed Consolidated Financial Statements (continued)

There were 0.7 million and 0.2 million of potential common shares which would be considered anti-dilutive for the three and nine months ended 31 December 2025, respectively. There were no potential common shares which would be considered anti-dilutive for the three and nine months ended 31 December 2024.

Potential common shares of 1.4 million and 1.1 million for the three and nine months ended 31 December 2025, respectively, and 0.7 million and 0.6 million for the three and nine months ended 31 December 2024, have been excluded from the calculation of diluted common shares outstanding as they are considered contingent shares which are not expected to vest.

Upon the completion of the acquisition of AZEK, the Company issued 148,861,701 shares of common stock on 1 July 2025.

Accounting Standards Issued But Not Yet Adopted

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09, Income Taxes (Topic 740). The amendments in this standard enhance income tax disclosures primarily related to the rate reconciliation and income taxes paid information. These amendments are effective for fiscal years beginning after 15 December 2024, with early adoption permitted. The Company will adopt ASU No. 2023-09 starting with its annual report for the fiscal year ending 31 March 2026 and will be required to make additional disclosures in the notes to the consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). The amendments in this standard require disaggregation of specific expense categories in the notes to the financial statements and a qualitative description of the remaining expense amounts not separately disaggregated. These amendments are effective for fiscal years beginning after 15 December 2026, and interim periods within fiscal years beginning after 15 December 2027, with early adoption permitted. The Company plans to adopt ASU No. 2024-03 starting with its annual report for the fiscal year ending 31 March 2028 and is currently evaluating the impact of the guidance to the consolidated financial statements.

2.  Business Combination

On 1 July 2025, the Company completed the acquisition of AZEK pursuant to the Agreement and Plan of Merger dated 23 March 2025, as amended, ("Merger Agreement") among JHI plc, Juno Merger Sub Inc. and AZEK. As a result of the acquisition, AZEK became a wholly-owned subsidiary of the Company.

The business combination was accounted for under the acquisition method of accounting. Under the acquisition method of accounting, the Company is required to measure identifiable assets acquired, liabilities assumed and any noncontrolling interests in the acquiree at their fair values as of the acquisition date. The Company’s accounting for the acquisition is preliminary. The acquisition-date fair value estimates for identifiable assets acquired and liabilities assumed are based on preliminary calculations and allocations, and these estimates and assumptions are subject to change as additional information is obtained during the measurement period, which may be up to one year from the acquisition date.

Pursuant to the Merger Agreement, each outstanding share of AZEK common stock was converted into the right to receive US$26.45 in cash and 1.0340 of James Hardie ordinary shares listed on the New York Stock Exchange. Incorporated into consideration transferred is the fair value of certain employee stock options which were calculated using a Black-Scholes option pricing model, as well as certain employee restricted stock units, which were calculated using the stock price on the transaction date. Finally, the consideration includes the entirety of the US$437.8 million of AZEK debt that was repaid by James Hardie on the acquisition date.

The following table summarizes the allocation of the purchase price to the identifiable assets acquired and liabilities assumed, based on their estimated fair values as of the acquisition date. The purchase price allocation was based on preliminary valuations and is subject to revisions as more detailed analyses are completed and additional information about the fair value of assets acquired and liabilities assumed become available.

(Millions of US dollars)	Assets Acquired and<br>Liabilities Assumed
Cash and cash equivalents	$	330.1
Accounts and other receivables	60.6
Inventories	280.0
Prepaid expenses and other current assets	60.3
Property, plant and equipment	838.2
Intangible assets	3,480.0
Other assets - non-current	134.8
Total assets acquired	$	5,184.0
Accounts payable and accrued liabilities	$	211.6
Other liabilities - current	73.9
Deferred tax liabilities, net	967.3
Other liabilities - non-current	149.9
Total liabilities assumed	$	1,402.7
Net assets acquired	$	3,781.3
Amount of goodwill recognized	$	4,612.2
Total consideration transferred	$	8,393.5

The Company has completed the preliminary valuation analyses necessary to assess the fair values of the assets acquired and liabilities assumed and the amount of goodwill to be recognized as of the acquisition date. These fair values were based on management’s estimates and assumptions; however, the amounts indicated above are preliminary in nature and are subject to adjustment as additional information is obtained and evaluated about the facts and circumstances that existed as of the acquisition date. Accordingly, there may be adjustments to the assigned values. The primary areas that remain preliminary include, but are not limited to, intangible assets including the preliminary assumptions used in their estimates of fair values and their respective estimated useful lives, the valuation of property, plant and equipment, real estate leases, certain tangible assets, income taxes, and residual goodwill. The final determination of the fair values, purchase consideration, related income tax impacts and residual goodwill will be completed as soon as practicable, and within the measurement period of up to one year from the acquisition date as permitted under GAAP. Any adjustments to provisional amounts that are identified during the measurement period will be recorded in the reporting period in which the adjustment is determined.

Goodwill of US$4,612.2 million arising from the acquisition is calculated as the excess of the purchase price over the net assets acquired and is attributable to expected synergies, expanded market opportunities, and enhanced delivery network capabilities. Goodwill related to this acquisition is expected to be nondeductible for tax purposes. As the valuation is preliminary, we have not yet finalized the assignment of goodwill to our reporting units, and no goodwill currently resides in our reportable segments. See Note 6 "Goodwill and Other Intangible Assets" for more information.

As described in more detail in Note 15 "Segment Information", the Company changed its segment reporting structure to reflect its new organizational structure commencing with the quarter ended 30 September 2025. Under the revised reporting structure, the legacy North America Fiber Cement segment was integrated with the acquired AZEK Exteriors business to form a new segment called Siding & Trim. Additionally, the Company created a Deck, Rail & Accessories segment which includes the remainder of the acquired AZEK business. The newly named Australia & New Zealand segment consists of the legacy Asia Pacific Fiber Cement segment, while the newly named Europe segment consists of the legacy Europe Building Products segment.

During the three and nine months ended 31 December 2025, the Company recorded acquisition-related costs as follows:

•Acquisition related expenses line item in the condensed consolidated statements of operations and comprehensive income statement of US$29.4 million and US$189.1 million for the three and nine months ended 31 December 2025, respectively, includes:

◦US$94.7 million of transaction costs for the nine months ended 31 December 2025; and

◦US$29.4 million and US$94.4 million of integration costs for the three and nine months ended 31 December 2025, respectively.

AZEK Results

AZEK results for the post acquisition period 1 July 2025 through 31 December 2025 were as follows:

	Three Months Ended<br>31 December 2025		Nine Months Ended<br>31 December 2025
(Millions of US dollars)	(unaudited)		(unaudited)
Net sales	$	275.0	$	620.1
Net loss	$	(64.1)	$	(112.9)

Included in the results of AZEK was a one-time increase in Cost of goods sold of US$47.9 million inventory step-up adjustment for the nine months ended 31 December 2025. Also included in the results is additional amortization of US$57.6 million and US$106.3 million for the three and nine months ended 31 December 2025, respectively, resulting from the recognition of identified finite-lived intangible assets resulting from the preliminary purchase price accounting and acquisition related costs of US$8.5 million and US$46.5 million, respectively.

Supplemental Pro Forma Results of Operations

The following unaudited supplemental pro forma financial information presents our consolidated results of operations as if the acquisition had been completed on 1 April 2024, but using the fair values of the assets acquired and liabilities assumed as of the closing date of the merger. This pro forma presentation does not include any impact of transaction synergies. The pro forma results are not necessarily indicative of our results of operations that actually would have been achieved had the acquisition been completed on the assumed date, nor are they necessarily indicative of future results.

	Nine Months Ended 31 December
(Millions of US dollars)	2025<br><br>(Unaudited)		2024<br><br>(Unaudited)
Net sales	$	3,864.2	$	3,974.0
Net income	$	60.2	$	345.8

The pro forma results include adjustments directly attributable to the business combination. The adjustments relate to purchase accounting, primarily amortization of intangible assets and the impact of

the acquisition financing. Included in the results for the nine months ended 31 December 2025 are acquisition related expenses of US$189.1 million.

3. Revenues

The Company's presentation of revenue by reportable segment most reasonably depicts how the nature, amount, timing and uncertainty of the Company's revenue and cash flows are affected by economic and market-specific factors. The Company recognizes revenues when the requisite performance obligation has been met, that is, when the Company transfers control of its products to customers per the arranged shipping terms, which are generally on delivery.

The following represents the Company's disaggregated revenues:

	Three Months<br>Ended 31 December				Nine Months<br>Ended 31 December
(Millions of US dollars)	2025		2024		2025		2024
Siding & Trim	$	788.3	$	719.3	$	2,196.1	$	2,144.4
Deck, Rail & Accessories	194.1		—		449.9		—
Australia & New Zealand	126.5		118.1		381.0		401.8
Europe	130.9		115.9		404.9		359.8
Total	$	1,239.8	$	953.3	$	3,431.9	$	2,906.0

The process by which the Company recognizes revenues is similar across each of the Company's reportable segments. The Company records estimated reductions in sales for customer rebates and discounts including volume, promotional, cash and other discounts. Rebates and discounts are recorded in Net sales based on management’s best estimate when products are sold. The estimates are based on historical experience for similar programs and products, and contractual obligations. Management reviews these rebates and discounts on an ongoing basis and the related accruals are adjusted, if necessary, as additional information becomes available.

4.  Inventories

Inventories consist of the following components:

	31 December		31 March
(Millions of US dollars)	2025		2025
Finished goods	$	490.6	$	243.9
Work-in-process	51.0		26.5
Raw materials and supplies	140.3		87.4
Provision for obsolete finished goods and raw materials	(16.1)		(10.7)
Total	$	665.8	$	347.1

Debt Facilities - New

Senior Secured Credit Facilities

In May 2025, James Hardie International Group Limited ("JHIGL"), JH North America Holdings Inc. ("JHNAH"), James Hardie International Finance Designated Activity Company ("JHIF"), James Hardie US Holdings Limited ("JHUSHL") and James Hardie Building Products Inc. ("JHBP") entered into a Credit and Guaranty Agreement (the "Credit Agreement"), with Bank of America, N.A. ("BofA"), as administrative and collateral agent.

The Credit Agreement provides for senior secured credit facilities (the "Credit Facilities") in an aggregate principal amount of US$3.5 billion, with terms as follows:

•a senior secured term "A" loan facility in an aggregate principal amount of US$750 million (the "Term A-1 Facility"), maturing 30 May 2028 with interest at a Term Secured Overnight Financing Rate ("SOFR") plus a margin varying from 1.25% to 1.875%;

•a senior secured term "A" loan facility in an aggregate principal amount of US$1.75 billion (the "Term A-2 Facility" and, together with the Term A-1 Facility, the "Term Facilities"), maturing 30 May 2030 with interest at a Term SOFR plus a margin varying from 1.375% to 2.00%; and

•a senior secured revolving credit facility in an aggregate principal amount of US$1.0 billion (the "Revolving Facility"), which includes a US$100 million sublimit for the issuance of letters of credit and a US$50 million sublimit for the borrowing of swing line loans, maturing 30 May 2030. Interest

F-17

James Hardie Industries plc

Notes to Condensed Consolidated Financial Statements (continued)

on the Revolving Facility will be at a Term SOFR plus a margin varying from 1.375% to 2.00%, and unutilized commitments are subject to a per annum fee ranging from 0.20% to 0.30%.

Debt issuance costs incurred in connection with the Credit Facilities are recorded as an offset to Long-term debt on the Company's condensed consolidated balance sheet as of 31 December 2025. These costs are being amortized as interest expense using the effective interest method over the stated terms.

On 1 July 2025, the Company drew down the entire US$2.5 billion on the Term Facilities to fund a portion of the cash consideration for the AZEK acquisition.

2031 and 2032 Senior Secured Notes

In June 2025, JHNAH completed its private offering of US$1.7 billion aggregate principal amount of senior secured notes (the "Notes"). The Notes were issued at par with US$700 million due 31 January 2031 (the "2031 Notes") and the remaining US$1.0 billion due 31 July 2032 (the "2032 Notes"). The 2031 Notes bear interest at a rate of 5.875% per annum and the 2032 Notes bear interest at a rate of 6.125% per annum.

The Company used the net proceeds from the Notes, together with proceeds of the Term Facilities and cash on hand, to (i) finance the aggregate cash consideration of the acquisition of AZEK (ii) to repay and terminate AZEK's existing debt and (iii) to pay fees and expenses related to the acquisition.

Debt issuance costs incurred in connection with the 2031 and 2032 Notes are recorded as an offset to Long-term debt on the Company’s condensed consolidated balance sheet as of 31 December 2025. These costs are being amortized as interest expense using the effective interest method over the stated terms.

The indenture governing the 2031 and 2032 Notes contains covenants that limit the ability of the Company and any of its restricted subsidiaries, to, among other things: create liens on certain assets to secure debt and to enter into certain sale-leaseback transactions. The Credit Facilities contain certain covenants that, among other things, restrict JHIGL and its restricted subsidiaries’ ability to incur indebtedness and grant liens other than certain types of permitted indebtedness and permitted liens, make certain restricted payments, and undertake certain types of mergers or consolidation actions.

The obligations under the Credit Facilities and Notes are (i) jointly and severally guaranteed on a senior secured basis by JHIGL, JHNAH, JHIF, JHUSHL and JHBP and; (ii) are secured by a lien on the equity interests of certain direct wholly owned material US restricted subsidiaries of JHIGL and the borrowers that are not restricted from being pledged pursuant to applicable regulatory requirements or applicable law.

Under the terms of the AFFA, the Company has rights of access to actuarial information produced for AICF by the actuary appointed by AICF, which is currently KPMG. The Company’s disclosures with respect to claims statistics are subject to it obtaining such information, however, the AFFA does not provide the Company an express right to audit or otherwise require independent verification of such information or the methodologies to be adopted by the approved actuary. As such, the Company relies on the accuracy and completeness of the information provided by AICF to the approved actuary and the resulting information and analysis of the approved actuary when making disclosures with respect to claims statistics.

AICF Funding

During fiscal year 2026, the Company will contribute A$193.6 million to AICF, excluding interest, in quarterly installments. Three payments of A$48.4 million were made on 1 July 2025, 1 October 2025 and 2 January 2026.

For the nine months ended 31 December 2025, the Company did not provide financial or other support to AICF that it was not previously contractually required to provide.

Restricted Investments

AICF invests its excess cash in time deposits, which are classified as held to maturity investments and the carrying value materially approximates the fair value for each investment. The following table represents the investments outstanding as of 31 December 2025:

Date Invested	Maturity Date	Interest Rate	A$ Millions
October 2025	16 October 2026	4.14%	70.0

9. Derivative Instruments

In May 2025, the Company entered into an interest rate swap agreement to manage interest rate risk related to the Company’s Term Facilities by swapping variable interest at a rate based on SOFR with a fixed rate of 3.79%. The interest rate swap agreement has a notional amount of US$1.0 billion and will expire on 30 June 2028.

On 1 July 2025, the Company met the requirements to designate the swap as a cash flow hedge. The fair value of the interest rate swap is estimated by using a valuation model based on observable market data, including yield curves. The gain (loss) is recorded in Accumulated other comprehensive loss and then reclassified into Interest, net in the same period in which the hedged transaction affects earnings. As of 31 December 2025, the Company expects to reclass approximately US$7.9 million (US$5.9 million after-tax) as a decrease to interest expense in the next 12 months.

For the three months ended 30 June 2025, the swap did not meet the requirements for hedge designation and the Company recorded a loss of US$11.6 million in Other expense (income), net.

The fair value of the interest rate swap and classification on the condensed consolidated balance sheets is as follows:

			Fair Value as of
(Millions of US dollars)	Fair Value Hierarchy	Balance Sheet Location	31 December 2025		31 March 2025
Interest rate swap	Level 2	Other current liabilities	$	12.2	$	—

Refer to Note 13 "Accumulated Other Comprehensive Loss" for further details of the effect derivative instruments.

10.  Commitments and Contingencies

Legal Matters

The Company is involved from time to time in various legal proceedings and administrative actions related to the normal conduct of its business, including general liability claims, putative class action lawsuits and litigation concerning its products.

F-21

James Hardie Industries plc

Notes to Condensed Consolidated Financial Statements (continued)

Although it is impossible to predict the outcome of any pending legal proceeding, management believes that such proceedings and actions should not, individually or in the aggregate, have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows, except as described in these condensed consolidated financial statements.

Australia Class Action Securities Claim

On 8 May 2023, a group proceeding (class action) was filed in The Supreme Court of Victoria, Australia by Raeken Pty Ltd against James Hardie Industries plc on behalf of persons who purchased certain James Hardie equity securities from 7 February 2022 through 7 November 2022. The litigation is being funded by a litigation funder in Australia, CASL Funder Pty Ltd. The proceeding includes allegations that James Hardie breached relevant provisions of the Corporations Act 2001 (Cth) and the Australian and Securities Investment Act 2001 (Cth), including with respect to certain forward-looking statements James Hardie made about forecasted financial performance measures during the period specified above. The Company believes the challenged statements were proper and is defending the matter. Currently, the Plaintiffs are seeking leave to amend their statement of claim for a second time, and, as a result the July 2026 trial date has been vacated with no new trial date set. As of 31 December 2025, the Company has not recorded a reserve related to this matter as the chance of loss is not probable and the amount of loss, if any, cannot be reasonably estimated.

Australian Tax Office (“ATO”) Audit

In February 2024, the ATO issued a transfer pricing position paper for income years ended 31 March 2011 through 31 March 2019, setting out the ATO’s view that certain profits related to arrangements with the Company’s technology holding company based in Ireland should be allocated to Australian subsidiaries of the Company and taxed in Australia. In October 2025, the Company and the ATO reached an agreement which finalized the tax audit being conducted by the ATO on the Company's Australian income tax returns for the years ended 31 March 2011 through 31 March 2019, settled all outstanding issues arising from this audit up to and including the year ended 31 March 2025, and provides greater clarity for future years. The agreed settlement was made without concessions or admissions of liability by either the Company or the ATO. During the nine months ended 31 December 2025, the Company recognized an income tax expense of US$18.2 million (A$27.6 million) and a corresponding non-cash reduction in the deferred tax assets relating to Australian net operating losses in respect of this settlement. There will be no additional taxes payable in respect of this settlement.

U.S. Class Action Securities Claim

On 24 October 2025, a putative class action was filed in United Stated District Court for the Northern District of Illinois by Laborers’ District Council and Contractors’ Pension Fund of Ohio against James Hardie Industries plc and its CEO and CFO on behalf of persons who purchased certain James Hardie equity securities from 20 May 2025 through 18 August 2025.

The proceeding includes allegations that James Hardie violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, 15 U.S.C. §§ 78j(b) and 78t(a) and Rule 10b-5 promulgated thereunder by the SEC, 17 C.F.R. § 240.10 b-5., including regarding its knowledge of customers destocking inventory in April and early May 2025 and statements on 20 and 21 May 2025 about inventory destocking occurring. The Company believes the challenged statements were proper and is defending the matter. The Company has not recorded a reserve related to this matter as the chance of loss is not probable and the amount of loss, if any, cannot be reasonably estimated.

Environmental

The operations of the Company, like those of other companies engaged in similar businesses, are subject to a number of laws and regulations on air, soil and water quality, waste handling and disposal. The Company’s policy is to accrue for environmental costs when it is determined that it is probable that an obligation exists and the amount can be reasonably estimated.

11.  Income Taxes

Income taxes payable represents taxes currently payable which are computed at statutory income tax rates applicable to taxable income derived in each jurisdiction in which the Company conducts business. During the nine months ended 31 December 2025, the Company paid taxes, net of refunds, of US$71.2 million.

Income tax expense differs from the statutory rate primarily due to the Company’s mix of pre-tax income by jurisdiction and foreign taxes on domestic income, plus discrete items including the impact of the ATO settlement agreement.

Deferred income taxes include net operating loss carry-forwards. At 31 December 2025, the Company had tax loss carry-forwards in Australia, New Zealand, Europe and the US of approximately US$69.1 million that are available to offset future taxable income in the respective jurisdiction. The Company establishes a valuation allowance against a deferred tax asset if it is more likely than not that some portion or all of the deferred tax asset will not be realized.

The Australian tax loss carry-forwards primarily result from current and prior year tax deductions for contributions to AICF. James Hardie 117 Pty Limited, the performing subsidiary under the AFFA, is able to claim a tax deduction for its contributions to AICF over a five-year period commencing in the year the contribution is incurred. At 31 December 2025, the Company recognized a tax deduction of US$94.4 million (A$145.1 million) for the current year relating to total contributions to AICF of US$674.5 million (A$967.5 million) incurred in tax years 2022 through 2026.

On 4 July 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, including reinstatement of federal bonus depreciation, deductions for domestic research and development expenditures, and modifications to the international tax framework. The enactment of OBBBA did not have a material impact on the Company’s condensed consolidated financial statements.

12.  Stock-Based Compensation

Total stock-based compensation expense consists of the following:

	Three Months<br>Ended 31 December				Nine Months<br>Ended 31 December
(Millions of US dollars)	2025		2024		2025		2024
Liability Awards	$	2.9	$	(0.4)	$	8.4	$	3.0
Equity Awards	8.8		5.4		28.4		17.7
Total stock-based compensation expense	$	11.7	$	5.0	$	36.8	$	20.7

Total stock-based compensation expense for the nine months ended 31 December 2025 includes replacement awards issued in connection with the AZEK merger.

F-23

James Hardie Industries plc

Notes to Condensed Consolidated Financial Statements (continued)

As of 31 December 2025, the unrecorded future stock-based compensation expense related to outstanding equity awards was US$64.0 million and will be recognized over an estimated weighted average amortization period of 2.0 years.

As of the acquisition date, the estimated fair value of the assumed equity awards was US$182.1 million, of which US$160.0 million was recognized as goodwill and the balance of US$22.1 million will be recognized as stock-based compensation expense over the remainder term of the replacement awards. The fair value of the replacement awards for services rendered through the acquisition date was recognized as a component of the purchase consideration, with the remaining fair value related to the post-combination services to be recorded as stock-based compensation over the remaining vesting period.

The Company used the Black-Scholes pricing model to estimate the fair value of replacement service-based stock option awards. The significant assumptions used for the stock option valuation include risk free interest rate of 3.75% - 3.88%, expected volatility of 35.0% - 40.0%, expected terms of 2.47 - 5.60 years, and expected dividend yield of 0.0%. The fair value of the replacement restricted stock units was based on the closing price on the acquisition date.

13.  Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss consists of the following at 31 December 2025:

(Millions of US dollars)	Cash Flow<br>Hedges		Pension<br>Actuarial<br>Gain		Foreign<br>Currency<br>Translation<br>Adjustments		Total

Australia & New Zealand segment

For the nine months ended 31 December 2024, the Company recorded US$57.3 million of exit costs related to its decision to shut down its manufacturing and wind-down commercial operations in the Philippines. The net assets remaining in the Philippines primarily consists of land and buildings, which the Company is actively marketing to sell.

General Corporate

During the three months ended 31 December 2025, the Company completed the sale of its Truganina greenfield site and received proceeds of US$108.2 million and recorded a gain on sale of US$26.2 million in General Corporate Costs.

15.  Segment Information

As of 31 December 2025, the Company has four reportable segments:

•Siding & Trim segment - Manufactures fiber cement and PVC exterior siding and trim products, as well as moulding, interior linings, and accessories in the United States. These products are sold in the United States and Canada.

•Deck, Rail & Accessories segment - Manufactures decking, railing, cladding, pergolas, cabanas and related accessories in the United States; these products are sold in the United States and Canada.

•Australia & New Zealand segment - Includes fiber cement products manufactured in Australia and sold in Australia and New Zealand.

•Europe segment - Includes fiber gypsum products and cement bonded boards manufactured in Europe, and fiber cement products manufactured in the United States that are sold in Europe.

The Company's General Corporate and unallocated Research and Development ("R&D") costs do not meet the applicable accounting guidance for separate disclosure as a reportable segment, and are reflected as reconciling items to consolidated Operating Income. General Corporate costs primarily consist of Asbestos adjustments, officer and employee compensation and related benefits, professional and legal fees, administrative costs, acquisition related costs and rental expense on the Company’s corporate offices, which are not allocated to the reportable segments. Unallocated R&D costs represented the costs incurred by the research and development centers which were costs not directly associated with one of our reportable segments. Beginning 1 July 2025, R&D costs are allocated to the segments. For the three months ended 31 December 2025, US$8.8 million was allocated to Siding & Trim, US$1.3 million to Australia & New Zealand and US$0.2 million to Europe. For the nine months ended 31 December 2025, US$16.5 million was allocated to Siding & Trim, US$2.5 million to Australia & New Zealand and US$0.4 million to Europe. The Company does not report total assets by segment as the Company’s Chief Operating Decision Maker does not assess performance, or allocate resources based on segment assets.

The Company does not report Interest, net for each segment as the segments are not held directly accountable for interest.
