Investigation into Potentially Misleading Assurances

The investigation is centered on the contrast between James Hardie's previous assurances and its recent performance. In May 2025, the company had told investors that its business model would allow it to “structurally grow through expansions and contractions.”

This claim came into question on August 19, 2025, when the company reported dismal Q1 2026 results.

James Hardie admitted that its North America sales volumes had declined by 12% year-over-year due to customers “destocking” their inventory from April to May. The company’s reduced outlook for the future was tied to these high inventory levels, potentially indicating that the earlier sales figures may have been artificially inflated by pushing products into the distribution channel.

Hagens Berman’s Investigation on Behalf of Investors

Hagens Berman is now investigating when and to what extent James Hardie’s management knew about this “inventory destocking” and whether they properly disclosed this information to investors.

“Our focus is on whether the company may have misled investors by presenting a facade of sustained demand, when in reality, they may have been overloading their channel partners with excess product,” said Reed Kathrein, the Hagens Berman partner leading the investigation.
