Commitments and Contingencies
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.
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 consolidated financial statements.
Australia Class Action Securities Claim
On May 8, 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 February 7, 2022 through November 7, 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 was vacated and is now reset for February 15, 2027. As of March 31, 2026, 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.
ATO Audit
In February 2024, the ATO issued a transfer pricing position paper for income years ended March 31, 2011 through March 31, 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 March 31, 2011 through March 31, 2019, settled all outstanding issues arising from this audit up to and including the year ended March 31, 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 fiscal year ended March 31, 2026, the Company recognized an income tax expense of $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.
US Class Action Securities Claims
On October 24, 2025, a putative shareholder class action was filed in the United Stated District Court for the Northern District of Illinois against James Hardie Industries plc and its CEO and then-CFO on behalf of persons who purchased or otherwise acquired James Hardie common stock between May 20, 2025, through August 18, 2025. On February 17, 2026, the Court appointed Oklahoma Firefighters Pension and Retirement System as lead plaintiff, and an amended complaint was filed on April 20, 2026. The case asserts claims for violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, alleging that the Defendants made material misstatements and omissions throughout the class period related to the strength of the Company’s North America Fiber Cement segment despite alleged customer inventory destocking.
During February and March 2026, shareholders filed two additional putative class actions in the Circuit Court of Cook County, Illinois and a third shareholder filed a putative class action in the Supreme Court of the State of New York, County of New York against James Hardie Industries plc and certain of its current and former directors and officers on behalf of former AZEK stockholders who received James Hardie common stock in exchange for shares of AZEK common stock in connection with the acquisition of AZEK (collectively, the “State Court Securities Cases”). One of the cases also named Ernst & Young LLP as a defendant. The State Court Securities Actions assert claims for violations of Sections 11, 12(a)(2) and 15 of the Securities Act of 1933, alleging that defendants made material misstatements and omissions regarding the strength of operations and customer inventory destocking in filings made in connection with James Hardie’s acquisition of AZEK. The Illinois actions were consolidated into a single action on April 20, 2026, and on May 12, 2026, the New York action was voluntarily discontinued. Plaintiffs in the consolidated Illinois action must file an amended complaint by June 26, 2026.
The Company believes the securities claims are without merit and intends to vigorously defend against them. The Company has not recorded a reserve related to these matters as the Company believes a loss is not probable and the possible amount of loss, or range of loss, is not reasonably estimable at this time.
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.

About Commitments Disclosures

Commitments and contingencies disclosures catalog a company's off-balance-sheet obligations and legal exposures — purchase commitments, guarantee arrangements, pending litigation, and regulatory proceedings. These items represent potential future cash outflows that may not appear as liabilities on the balance sheet until they become probable and estimable.

Key signals: litigation reserves and disclosed loss ranges quantify management's estimate of legal exposure, but unquantified "reasonably possible" losses often represent the larger risk. Watch for changes in language around pending cases — shifts from "remote" to "reasonably possible" or increases in estimated loss ranges signal deteriorating outcomes. Unconditional purchase obligations and take-or-pay contracts create fixed cost structures that reduce operational flexibility. Guarantee arrangements for subsidiaries or joint ventures can create cascading obligations. Compare the total commitment schedule against projected free cash flow to assess whether the company can meet its obligations without additional financing.
