LOUISIANA-PACIFIC CORP

18. SEGMENT INFORMATION

We operate inthree segments: Siding, OSB, and LPSA. Our business units have been aggregated into these three segments based upon the similarity of economic characteristics, customers, and distribution methods. Our results of operations are summarized below for each of these segments separately as well as for the “Other” category, which comprises other products that are not individually significant.

•Our Siding segment serves diverse end markets with a broad product offering, including LP® SmartSide® Trim & Siding, LP® SmartSide® ExpertFinish® Trim & Siding, LP BuilderSeries® Lap Siding, and LP®Outdoor Building Solutions™ (collectively referred to as Siding Solutions). Our Siding Solutions products consist of a full line of engineered wood siding, trim, soffit, and fascia.

•Our 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 TechShield® Radiant Barrier, LP WeatherLogic® Air & Water Barrier, LP Legacy® Premium Sub-Flooring, LP NovaCore® Thermal Insulated Sheathing, LP FlameBlock® Fire-Rated Sheathing, and LP TopNotch® 350 Durable Sub-Flooring). OSB is manufactured using wood strands arranged in layers and bonded with resins.

•Our LPSA segment manufactures and distributes LP OSB structural panel and Siding Solutions products in South America and certain export markets. This segment also sells and distributes a variety of companion products to support the region’s transition to wood frame construction. The LPSA segment carries out manufacturing operations in Chile and Brazil and operates sales offices in Argentina, Brazil, Chile, Colombia, Mexico, Paraguay, and Peru.

We evaluate the performance of our business segments based on net sales and segment Adjusted EBITDA. Accordingly, our chief operating decision maker evaluates performance and allocates resources based primarily on net sales and segment Adjusted EBITDA for our business segments. Segment Adjusted EBITDA is defined as income attributed to LP before interest expense, provision for income taxes, depreciation and amortization, and excludes stock-based compensation expense, loss on impairment attributed to LP, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, pension settlement charges, and other non-operating items.

During the year ended December 31, 2023, we updated our definitions of Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS to exclude other business exit charges not classified as discontinued operations. Business exit charges consist of inventory and other asset impairment and exit charges related to the exit of other businesses not individually significant. We consider business exit charges to be outside the performance of our ongoing core business operations and believe that presenting Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS excluding business exit charges provides increased transparency as to the operating costs of our current business performance. We did not revise prior years’ Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS amounts because there were no significant costs similar in nature to these items.
