Sean Steuart's questions to Louisiana-Pacific Corp (LPX) leadership • Q2 2025
Question
Sean Steuart of TD Cowen questioned the dynamics of the OSB cost curve across LP's mill portfolio and how it influences downtime decisions. He also requested an updated perspective on the timing and economics of the Houlton Siding mill expansion.
Answer
Chair & CEO Brad Southern explained that the OSB cost curve is relatively flat at the mill level, so downtime decisions are driven more by delivered margin, which considers geographic location and transportation costs, rather than just production cost. Regarding the Houlton project, Southern stated that detailed engineering is ongoing to account for inflation, but returns still appear healthy. He anticipates providing more specific details on costs and returns in the next one or two quarters.
