James Hardie's shares plummet as financial results miss expectations and acquisition skepticism grows.

James Hardie Industries, a leading fiber cement building products company, saw its shares fall 27.9% year-to-date following disappointing financial results and uncertain forward guidance. FY25 adjusted net income was $644.3M, slightly above expectations, but FY26 outlook projected low single-digit growth, below analyst forecasts. The $8.75B acquisition of AZEK faced investor skepticism over price and transparency, though some analysts see long-term growth potential.
