High Interest Rates, Low Home Sales: Housing Siding Leader Drops 6% in a Day

James Hardie Industries Plc (JHX) shares closed at $20.50 on the New York Stock Exchange on the 29th, down 5.94% from the previous day. Market capitalization fell to approximately $11.9 billion (about KRW 17 trillion), erasing roughly $670 million (around KRW 900 billion) in a single session. Trading volume totaled 4.22 million shares.

In its third-quarter results for the fiscal year ending December 31, 2025, the company cited weakened purchasing power in the North American and Asia-Pacific housing markets and heavy inventory burdens, confirming a slowdown in growth. With the next quarterly earnings release scheduled for May 19, investors are watching closely for insights into the U.S. housing market and construction trends.

James Hardie Industries, headquartered in the United States and Ireland, is a global building materials company and the world’s leading producer of fiber cement siding and cladding. Its large exposure to the North American single-family and remodeling markets makes it particularly sensitive to U.S. interest rates and housing-market cycles.
