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 Media Release, the Management 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 its 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 expenses, 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.” In addition, this Management’s Analysis of Results includes financial measures and descriptions that are considered to not be in accordance with GAAP, but which are consistent with financial measures reported by Australian companies. Since James Hardie prepares its condensed consolidated financial statements in accordance with GAAP, the Company provides investors with definitions and a cross-reference from the non-GAAP financial measure used in this Management’s Analysis of Results to the equivalent GAAP financial measure used in the Company's Condensed Consolidated Financial Statements. See the section titled “Non-GAAP Financial Measures.”

For the quarter, the Company delivered record Adjusted EBIT and Adjusted Net Income of US$240.0 million and US$178.9 million, respectively.

•Net salesremained flat at US$998.8 million due to an increase in average net sales price for all three operating segments offset by a volume decrease of 7% resulting from weaker global housing markets.

•Adjusted EBIT margin increased 2.1 percentage points to 24.0% driven by strong EBIT margin growth in all three operating segments.

•Net income of US$151.7 million includes an asset impairment charge of US$20.1 million related to the strategic decision to cancel and sell the Truganina greenfield land.

•Adjusted Net income of US$178.9 million is attributable to strong performance in each of our regions, and excludes the US$20.1 million impairment charge.

Management's Analysis of Results: James Hardie - 2nd Quarter Fiscal Year 2024 6

OPERATING RESULTS

Q2 FY24 vs Q2 FY23 (€)

Net sales increased 5% primarily related to a 20% increase in average net sales price and a €3.3 million favorable true-up related to customer rebate estimates, partially offset by a 15% decrease in volumes. The growth in average net sales price resulted from our strategic price increases and favorable product mix. The volume decrease primarily resulted from lower fiber gypsum volumes as housing market activity decreased.

The increase in gross margin is attributable to the following components:

Higher average net sales price	13.0	pts
Higher production and distribution costs	(4.3	pts)
Total percentage point change in gross margin	8.7	pts

Higher production and distribution costs resulted from increased costs of labor and energy, partially offset by lower freight and paper costs.

SG&A expenses increased 18% primarily due to higher employee and marketing costs. As a percentage of sales, SG&A expenses increased 2.0 percentage points.

EBIT margin of 10.7% increased 6.4 percentage points primarily driven by higher gross margin, partially offset by higher SG&A expenses.

Six Months FY24 vs Six Months FY23 (€)

Net sales increased 2% primarily related to a 21% increase in average net sales price, partially offset by a 17% decrease in volumes. The growth in average net sales price was driven by our strategic price increases and a higher value product mix. The volume decrease primarily resulted from lower fiber gypsum volumes as housing market activity decreased.

The increase in gross margin is attributable to the following components:

Higher average net sales price	12.9	pts
Higher production and distribution costs	(7.6	pts)
Total percentage point change in gross margin	5.3	pts

Higher production and distribution costs resulted from increased costs of gypsum and energy, partially offset by lower freight and paper costs.

SG&A expenses increased 16% primarily due to higher employee and marketing costs. As a percentage of sales, SG&A expenses increased 2.2 percentage points.

General Corporate

Results for General Corporate were as follows:

US$ Millions	Three and Six Months Ended 30 September
		Q2 FY24		Q2 FY23		Change %	6 Months FY24		6 Months FY23		Change %
General Corporate SG&A expenses		$	40.5	$	28.0	45	$	73.9	$	51.7	43

General Corporate costs		$	57.1	$	19.9	187	$	90.8	$	30.7	196

General Corporate SG&A expenses for the three and six month periods increased US$12.5 million and US$22.2 million, respectively, driven by the recording of a provision for a receivable in Q2 FY24, higher stock compensation expenses and higher employee costs.

The Asset impairment charge of US$20.1 million is related to the strategic decision to cancel the Truganina greenfield project and sell the land.

Asbestos adjustments primarily reflect the non-cash foreign exchange re-measurement impact on asbestos related balance sheet items, driven by the change in the AUD/USD spot exchange rate from the beginning balance sheet date to the ending balance sheet date, for each respective period. In addition, these amounts are partially offset by gains and losses on foreign currency forward contracts related to future AICF payments.

Readers are referred to Note 7 of our 30 September 2023 condensed consolidated financial statements for further information on asbestos.

Interest, net

US$ Millions	Three and Six Months Ended 30 September

Interest, net		$	4.5	$	8.2	(45)	$	10.3	$	17.0	(39)

Interest, net for the three and six month periods decreased primarily due to higher capitalized interest related to our capital expansion projects, and higher net AICF interest income driven by higher interest rates and AICF investments. These increases were partially offset by higher gross interest expense resulting from higher average outstanding balances and interest rates on our revolving credit facility.

Higher Adjusted net income for the three and six month periods was primarily driven by higher EBIT in our North America, Asia Pacific and Europe segments, partially offset by higher general corporate SG&A expenses and adjusted income tax expense. In addition, prior year included a US$8.9 million gain, net of tax, related to the sale of land in Europe.

Liquidity and Capital Allocation

Our cash position increased US$41.3 million, from US$113.0 million at 31 March 2023 to US$154.3 million at 30 September 2023. We also have US$453.7 million of available borrowing capacity under our revolving credit facility at 30 September 2023.

In October 2023, we paid down the entire US$140.0 million balance on our revolving credit facility. We also entered into a new five year US$300.0 million Term Loan Agreement, maturing October 2028.

During fiscal year 2024, we will contribute A$137.5 million to AICF, excluding interest, in quarterly installments; the first two payments of A$34.4 million were made on 3 July 2023 and 3 October 2023.

Based on our existing cash balances, together with anticipated operating cash flows and unutilized credit facilities, we anticipate we will have sufficient funds to invest in our organic growth, including capital expenditures, while meeting our planned working capital, share repurchase and other expected cash requirements for the next twelve months.

Capital Management

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

•Invest in organic growth

•Maintain a flexible balance sheet

•Deploy excess capital to shareholders

For the quarter ended 30 September 2023, we repurchased 2.4 million shares for US$72.3 million at an average per share price of US$29.43. This completes our US$200 million share buyback program announced in November 2022.

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.
