Hagens Berman Investigating Jamies Hardie (JHX) After 34% Plunge Due to Inventory Destocking

JHX Investors with Losses Encouraged to Contact Firm

SAN FRANCISCO, Dec. 3, 2025 /PRNewswire/ -- National shareholder rights law firm Hagens Berman reminds investors that the deadline to move the Court for appointment as lead plaintiff in the securities class action lawsuit against James Hardie Industries plc (NYSE: JHX) is December 23, 2025.

The lawsuit alleges that James Hardie and its executives misled investors by touting strong growth in its crucial North America Fiber Cement segment while concealing that the growth was unsustainable and fueled by undisclosed sales practices with its channel customers. The stock subsequently plummeted 34% when the truth was allegedly revealed.

"Our investigation focuses on whether James Hardie's executives made statements that were materially false by claiming customer inventory levels were 'normal' when, in reality, they were experiencing aggressive inventory destocking driven by prior sales inflation," said Reed Kathrein, the Hagens Berman partner leading the litigation. "We are scrutinizing the significant inventory loading, which allegedly caused investors to purchase stock at artificially inflated prices. We urge investors in James Hardie who suffered significant losses to contact the firm now to discuss their rights."

Legal Analysis: Undisclosed Sales Practices & Inventory Risk

The complaint details the alleged gap between the Company's public assurances of sustainable demand and the undisclosed reality of inventory risk in its North American segment.

The lawsuit covers investors who purchased James Hardie securities between May 20, 2025, and August 18, 2025. Furthermore, Hagens Berman's investigation is examining the sudden CFO replacement announced on November 17, 2025, as a potential related indicator of the alleged issues.

The Lead Plaintiff Deadline is December 23, 2025.
