What Louisiana-Pacific Corporation told the SEC could break it.
Louisiana-Pacific's results ride on commodities at both ends. Its primary raw material is wood fiber, sourced mainly from timber, so input cost and availability are a core exposure. On the output side it has a high product concentration in oriented strand board — about 33% of North American net sales in 2025 — which is subject to volatile commodity pricing it has limited ability to influence. Trade policy adds to its cost base: new and increased U.S. tariffs have already imposed additional expense (roughly $7–8 million across its 2025 segments) and could further disrupt its supply chains and raise raw-material costs.
3 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Commodity & input dependence
- wood fiber / timber (primary raw material)medium
Wood fiber, sourced primarily from timber, is the primary raw material across most LP operations — a key input-cost and availability exposure.
“Wood fiber is the primary raw material used in most of our operations, and the primary source of wood fiber is timber.”
SEC filing →As of 2026 - OSB commodity price concentrationmedium
High product concentration in OSB (~33% of North American net sales in 2025) makes LP highly sensitive to volatile commodity OSB pricing, over which it has limited influence.
“We have a high degree of product concentration in OSB, which is subject to commodity pricing and associated price volatility. OSB accounted for about 33% of our North American net sales in 2025 and 43% in each of 2024 and 2023.”
SEC filing →As of 2026
Regulatory & policy
- U.S. tariffs on imported products/materialsmedium
New/increased U.S. tariffs have already imposed additional costs (e.g., ~$7–8M of tariff expense in 2025 segments) and could disrupt LP's supply chains and raise raw-material costs.
“Steps taken by the U.S. government to apply new, or increase existing, tariffs on certain products and materials imported into the U.S. could potentially disrupt our existing supply chains and have imposed, and could continue to impose, additional costs on our business, including costs with respect to raw materials upon which our business depends.”
