LP Building Solutions (LP), a leading manufacturer of high-performance building products, today announced that it will indefinitely curtail oriented strand board (OSB) production at its Jasper, Texas facility beginning in October 2026 in response to soft demand.

The Jasper facility has an annual production capacity of approximately 475 million square feet on a 3/8-inch basis.

The decision follows a review of production requirements across LP's manufacturing network and reflects current conditions in the OSB market. In evaluating its options, the company considered a range of factors, including operating costs, capital requirements, logistics, and long-term asset utilization.

"Current market conditions require us to align OSB production with demand," said LP CEO Jason Ringblom. "While the near-term environment for OSB remains challenging, we are confident in LP's strategy and our ability to create long-term value. Taking action now allows us to operate efficiently through the cycle while maintaining the flexibility to respond as market conditions improve. This decision is not a reflection of the performance or commitment of the Jasper team, whose contributions have helped strengthen LP for many years."

LP will continue to evaluate market conditions and determine appropriate production levels across its system, including opportunities to restart curtailed capacity when warranted.

LP recognizes the impact this decision will have on its Jasper team members and is committed to supporting them through the transition. The company will provide job search and career transition support and help employees identify and apply for open positions at other LP facilities.
