James Hardie Industries Faces Class Action Lawsuit: Investor Alert Issued

Investor Alert: James Hardie Industries Under Legal Scrutiny

On December 8, 2025, the national plaintiffs' law firm, Berger Montague PC, announced a class action lawsuit against James Hardie Industries plc, listed on the NYSE as JHX. This legal action is centered around allegations that the company made misleading statements regarding the performance of its core North American Fiber Cement segment, impacting investors who bought shares during a defined Class Period from May 20, 2025, to August 18, 2025.

## What the Allegations Entail
The crux of the lawsuit states that during the Class Period, James Hardie falsely represented that demand for their products remained robust and that inventory levels were stable. However, internal knowledge suggested otherwise. By April and early May 2025, there were indications that distributors were actively reducing their stock, a fact that was allegedly concealed from investors.

The situation escalated dramatically on August 19, 2025, when James Hardie disclosed a noteworthy 12% decline in this segment. The company attributed this substantial drop to a "normalization of channel inventories," while also hinting at a continuing weakness in demand. This revelation had a catastrophic effect on the company’s stock prices, which plummeted by more than 34%, resulting in significant financial losses for investors who had acted on the earlier, misleading information.

### Deadlines for Investors
Investors who purchased James Hardie securities during the specified Class Period have a crucial window to file a motion to be named as lead plaintiff in the class action. The deadline for such actions is set for December 23, 2025. The firm emphasizes the importance of acting swiftly to ensure that rights are preserved, and those interested can learn more about the steps involved.
