Future Outlook

LP Building Solutions reaffirms its full-year 2025 Siding Adjusted EBITDA guidance of approximately $430 million on $1.68 billion in net sales, representing about 8% year-over-year growth and a 26% margin. The company projects fourth-quarter 2025 Siding net sales of approximately $370 million (3% growth) and Siding Adjusted EBITDA of approximately $82 million (22% margin). Consolidated Adjusted EBITDA for the full year is guided at approximately $420 million, with Q4 consolidated Adjusted EBITDA expected to be around $32 million. OSB Adjusted EBITDA is projected to be negative $45 million for Q4 2025 and $0 million for the full year 2025, based on current OSB prices.

Management Comments

• LP is providing financial guidance for the fourth quarter of 2025 and full year 2025 based on current plans and expectations.

Industry Context

The building products industry is experiencing mixed demand, with strong performance in LP's Siding segment driven by higher selling prices and volumes, indicating resilience in certain housing market segments. However, the significant decline in OSB net sales and Adjusted EBITDA reflects a challenging commodity market environment, likely influenced by broader economic conditions and supply/demand dynamics for structural panels. U.S. single-family housing starts saw a slight decrease in Q3 2025 compared to Q3 2024, while multi-family starts increased, suggesting a shift in residential construction activity that impacts demand for different product categories.

Stakeholder Impact

• Shareholders: Significant decrease in net income and diluted EPS could negatively impact investor sentiment and share price. Dividends were paid ($19 million in Q3), indicating continued return of capital.
• Employees: No direct impact mentioned, but operational challenges in OSB could imply future pressures.
• Customers: Siding customers benefit from continued product availability and innovation (ExpertFinish growth). OSB customers face market price fluctuations.
• Creditors: Total liquidity of $1.1 billion suggests a strong financial position to meet obligations despite reduced profitability.

Next Steps

• LP will hold a conference call to discuss this release on November 5, 2025, at 11 a.m. Eastern Time (8 a.m. Pacific Time).
• The recorded webcast and accompanying presentation will be available to the public on investor.lpcorp.com.

Key Dates

Recommendation

The company's Q3 2025 results show a stark contrast between its strong Siding segment, which continues to grow sales and maintain healthy margins, and its struggling OSB segment, which posted a significant loss. While the Siding business provides a solid foundation and positive long-term outlook, the severe drag from OSB, coupled with a substantial decline in overall net income and Adjusted EBITDA, creates near-term uncertainty. The reaffirmed full-year Siding guidance is a positive, but the overall consolidated guidance reflects the OSB weakness. Investors should hold to monitor the performance of the OSB segment and the company's ability to mitigate commodity price volatility, while benefiting from the robust Siding business.
