About James Hardie Industries

James Hardie Industries is a global building materials company known for manufacturing fiber cement siding and related products. Operations are concentrated in North America, which accounts for a substantial majority of net sales.

The company also pursued growth through the acquisition of AZEK, a U.S. decking manufacturer, through a significant merger announced in March 2025 and completed in July 2025.

The Allegations

The lawsuit alleges that, during the class period, James Hardie and certain executives made false and misleading statements about the strength and demand of its North America Fiber Cement segment. Plaintiffs contend the company’s reported growth was driven by inventory loading and channel stuffing, not genuine end-market demand.

On the Q4 FY2025 earnings call (May 20, 2025), when asked about channel inventory and the risk of destocking, management told investors: “We are seeing normal stock levels out there just as a general statement.” They also highlighted the commercial posture of the sales force, saying, “Nobody in the industry has a sales force like James Hardie.”

According to the complaint, management already knew by April and early May 2025 that customers had begun destocking, yet continued to reassure investors that the segment remained strong.

On August 19, 2025, James Hardie disclosed a 12% decline in North America Fiber Cement sales and attributed the drop to customer destocking first identified in April and May, describing a “normalization of channel inventories” expected to weigh on results for at least the next two quarters.

Following this news, on August 20, 2025, the stock fell 34%, dropping from $28.43 per share on August 19 to $18.64 the next day, causing investors significant harm.
