The James Hardie Industries (JHX) Securities Class Action

The lawsuit, Laborers’ District Council & Contractors’ Pension Fund of Ohio v. James Hardie Industries PLC., et al., 25-cv-13018 (N.D. Ill.), filed on behalf of all investors who purchased or acquired James Hardie common stock—which converted from American Depositary Shares on July 1, 2025—between May 20, 2025, and August 18, 2025 (the "Class Period"), seeks damages for violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5.

The action centers on James Hardie’s North America Fiber Cement segment, which the company states generates about 80% of its total earnings. The plaintiffs allege that despite the company starting to observe significant inventory destocking by its North American channel partners in April and early May 2025, management publicly denied the trend and assured investors of the segment’s sustained strength.

Specifically, the complaint highlights statements made by company executives on or around May 20 and 21, 2025, which it claims falsely represented that customer demand remained robust and expressly denied that inventory destocking was occurring. The plaintiffs contend that these assurances concealed an underlying problem: sales were artificially inflated by “inventory loading by channel partners, with the hallmarks of fraudulent channel stuffing,” rather than genuine, sustainable customer demand.

This alleged deception came to a head on August 19, 2025, when James Hardie belatedly disclosed a sharp decline in performance. The company reported that sales in the North America Fiber Cement division had dropped by 12%, attributing the decline to the very customer destocking it had previously denied, which management now admitted had been discovered "in April through May."

Company CEO and Executive Director Aaron Erter sought to frame the downturn as a “normalization of channel inventories,” but cautioned that the impact was expected to affect sales for at least the next two quarters.

The market’s reaction was severe and swift. Following the disclosure, James Hardie’s common stock dropped by over 34%.

The plaintiffs argue that this precipitous decline—and the significant losses suffered by investors—was a direct result of the defendants’ alleged wrongful acts and omissions during the Class Period. The lawsuit aims to recover damages on behalf of the Class Members who were financially injured by the sudden reversal of the company’s reported financial health.
