Sean Steuart's questions to LOUISIANA-PACIFIC (LPX) leadership • Q2 2025
Question
Sean Steuart of TD Cowen asked about OSB operational dynamics, specifically the cost curve variance across LP's mill portfolio and how it informs downtime decisions. He also requested an updated perspective on the timing and economics of the Houlton Siding mill expansion.
Answer
CEO Brad Southern explained that the OSB cost curve is relatively flat at the mill level, so downtime decisions are primarily driven by delivered margin, which considers geographic location, transportation costs, and local demand, rather than just variable production costs. Regarding the Houlton project, he stated that detailed engineering is ongoing and more specific cost and return details will be available in the next one or two quarters, noting the project's returns remain healthy despite inflation.
