LOUISIANA-PACIFIC CORP

15. SEGMENT INFORMATION

The Company defines its operating segments as those operations that engage in business activities from which revenues are earned and expenses incurred, for which discrete financial information is available, and that are regularly reviewed to analyze performance and allocate resources by the chief operating decision maker (“CODM”), the Company’s Chief Executive Officer.

Change in Reportable Segments

The Company conducts business through three operating segments: Siding, OSB and LP South America (LPSA). In the fourth quarter of 2025, the Company determined that LPSA did not meet the reportable segment criteria and beginning with the fourth quarter of 2025, the financial information for the LPSA operating segment is included in Other. These changes had no impact on our consolidated results of operations or financial position. Prior period segment information has been recast to conform to our current presentation. Our other operating segments, Siding and OSB remain reportable operating segments. Other now comprises our South American operations and other products that are not individually significant.

•The Siding segment serves diverse end markets with a broad product portfolio of engineered wood siding, trim, soffit, and fascia. Our Siding is offered primed (LP® SmartSide® Trim & Siding, LP BuilderSeries® Lap Siding, and LP®Outdoor Building Solutions®) and pre-finished (LP® SmartSide® ExpertFinish® Trim & Siding) to meet the needs of builders and installers in new construction and repair and remodeling applications.

•The OSB segment manufactures and distributes OSB structural panel products, including the innovative value-added OSB product portfolio known as LP® Structural Solutions (which includes LP® FlameBlock® Fire-Rated Sheathing, LP WeatherLogic® Air & Water Barrier, LP® TechShield® Radiant Barrier, LP Legacy® Premium Sub-Flooring, and LP® TopNotch® 350 Durable Sub-Flooring).

The accounting policies of the segments are the same as those described in the Company’s summary of significant accounting policies. We evaluate the performance of our operating segments based on segment Adjusted EBITDA, which the CODM uses to evaluate performance and allocate resources.

Segment Adjusted EBITDA is defined as net income before interest expense, provision for income taxes, depreciation and amortization, and excludes stock-based compensation expense, loss on impairment, business exit credit and charges, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, pension settlement charges, and other non-operating income (expense).

The CODM uses segment Adjusted EBITDA predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a quarterly basis when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses segment Adjusted EBITDA to assess the relative performance of each segment and to determine the compensation of certain employees.
