James Hardie Industries shares plunged by up to 37% following a disappointing full-year earnings forecast and a 28% year-over-year profit decline, attributed to weak demand in the US housing market, particularly in Texas, Florida, and Georgia. This marked the company's largest one-day drop since 1973. Analysts have cut price targets amid concerns over the US housing sector, which also impacted other companies. Australian plumbing supplies firm Reece Group experienced its steepest share decline in nearly 50 years after reporting a drop in full-year profit and issuing a warning about ongoing weakness in the US housing market. Meanwhile, Australia's Santos reported a 22.3% fall in half-year profit due to declines in LNG and oil prices but extended exclusivity for an $18.7 billion offer led by ADNOC. Additionally, Regal Partners shares fell after reporting lower half-year profit results.
