L1 Long Short Fund stated the following regarding James Hardie Industries plc (NYSE:JHX) in its Q2 2026 investor update:
“James Hardie Industries plc (NYSE:JHX) (+46%) shares recovered over the quarter following easing Middle East tensions and on management’s release of a constructive FY27 outlook, which included a pathway to return the core North American fibre cement business to volume growth, despite a subdued U.S. housing market. We expect this volume recovery to be supported by normalisation of channel inventory following the 2025 destocking period, improving execution in repair & remodel / smaller-builder channels, the Trim-Over installation method, competitor exits and continued material conversion from vinyl and wood.
In our view, the market is still applying a discounted multiple to James Hardie to reflect recent execution, governance and housing-cycle concerns. As these issues are progressively addressed, we believe there is scope for both earnings growth and recovery in the valuation multiple over time.”
