Shine Lawyers is investigating a potential class action against James Hardie Industries plc (James Hardie). You are eligible to register for the investigation if you acquired an interest in James Hardie securities between21 May 2025 and 19 August 2025.
What is the James Hardie Class Action Investigation about?
James Hardie is a publicly listed company, traded on the New York Stock Exchange (NYSE) and Australian Securities Exchange (ASX).
On 21 May 2025, James Hardie published its results for the 2025 financial year and its financial guidance for FY26.
On 20 August 2025, James Hardie released its results for the first quarter of FY26 and a revised (downgraded) FY26 financial guidance. In the days following this announcement, the company’s share price fell by over 30%, causing significant losses to investors.
Shine Lawyers’ investigation examines whether this loss was caused by any:
breaches of James Hardie’s continuous disclosure obligations; and/or
misleading or deceptive conduct.
In particular, it focuses on whether James Hardie:
had reasonable grounds for issuing and maintaining the FY26 guidance it released on 21 May 2025;
should have disclosed its Q1 FY26 results and downgraded FY26 guidance earlier to investors.

When Governments, large companies or institutions do the wrong thing and people are harmed or suffer loss as a result, an individual can have little to no means of bringing a legal claim.
Class actions are an important mechanism within Australia’s legal system that allow large groups of people to come together to pursue a claim collectively.
For a class action to take place, there are three criteria that need to be met:
there must be 7 or more people that have claims against the same defendant; and
the claims relate to the same or similar circumstances; and
the claim must relate to at least one common issue of law or fact.

How long do class actions take to resolve?
It can take up to several years for a class action to resolve. The time taken from case commencement through to resolution and settlement administration depends on the particular case, and the nature of the claim.
