Owens Corning Segments Disclosure
3. SEGMENT INFORMATION
Effective January 1, 2025, due to a strategic shift in how we manage our business as a result of the GR Agreement, we are presenting the GR business as a discontinued operation. We reorganized our reportable segments to align to our new operating and management structure. As a result, all prior period information was recast to reflect this change. The Company now has three reportable segments: Roofing, Insulation and Doors. The Company's vertically integrated glass nonwoven business that supports the Company’s Roofing business and other building products customers, along with its structural lumber business, were integrated into the Roofing segment. Two glass melting plants, which make fiber for the nonwoven business, were integrated into the Insulation segment. Unless otherwise specified, the information in the note refers to only the continuing operations of the Company.
Operating segments are aggregated into reportable segments based on consideration of the following factors: similarity of economic characteristics, the nature of business activities, the management structure directly accountable to our chief operating decision maker ("CODM") for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors. Accounting policies for the segments are the same as those for the Company. The Company’s three reportable segments are defined as follows:
Roofing – Within our Roofing segment, the Company manufactures and sells residential roofing shingles, oxidized asphalt materials, roofing components and composite lumber primarily used in residential construction. Roofing also manufactures and sells glass mat and specialty veil materials used in building and construction applications.
Insulation – Within our Insulation segment, the Company manufactures and sells thermal and acoustical batts, loose fill insulation, spray foam insulation, wet use chopped strand, foam sheathing and accessories. It also manufactures and sells glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated stone wool insulation, cellular glass insulation, and foam insulation used in above- and below-grade construction applications.
Doors - Within our Doors segment, the Company manufactures and sells interior and exterior doors and door systems primarily used in residential construction.
NET SALES
The following tables show a disaggregation of our net sales by segment and geographic region. Corporate eliminations (shown below) largely reflect intercompany sales from Insulation and Roofing. External customer sales are attributed to geographic region based upon the location from which the product is sold to the external customer.

(a) Net sales from our operations in the U.S. are $8,270 million, $8,121 million and $6,796 million in 2025, 2024 and 2023, respectively.
Our contracts with customers are broadly similar in nature throughout our reportable segments, but the amount, timing and uncertainty of revenue and cash flows may vary in each reportable segment due to geographic and end-market economic factors.
Sales to major customers - The Company had two customers that exceeded 10% of consolidated net sales for the twelve months ended December 31, 2025, December 31, 2024 and December 31, 2023. The first customer, which is a customer of the Roofing, Insulation and Doors segments, accounted for approximately 16%, 15% and 12% of the Company's consolidated net sales in 2025, 2024 and 2023, respectively. The second customer, which is a customer of the Roofing and Insulation segments, accounted for approximately 12%, 12% and 14% of the Company's consolidated sales in 2025, 2024 and 2023, respectively.
In North America, sales are primarily related to the residential housing market and non-residential applications. Residential market demand is driven by U.S. housing starts and repair and remodeling activity (influenced by existing home sales, seasonal home improvement and damage from major storms). Significant portions of our residential products across our three reportable segments are used interchangeably in both new construction and repair and remodeling, and our customers typically distribute (or use) the products for both applications. North American non-residential revenues are largely driven by North America industrial production growth, commercial construction activity and overall economic conditions in the U.S.
Outside of North America (Europe and Rest of world), sales are primarily related to non-residential applications and, to a lesser extent, residential applications in certain countries. Throughout the international regions, demand is primarily driven by industrial production growth, commercial construction activity and overall economic conditions in each respective geographical region.
EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION
Effective January 1, 2025, we changed our segment measure of profitability for our reportable segments from Earnings before interest and taxes ("EBIT") to Earnings before interest, taxes, depreciation and amortization (“EBITDA”), as the measure used for purposes of making decisions about allocating resources to the segments and assessing performance. Segment EBITDA is the principal measure used by the CODM to assess segment performance and make decisions on the allocation of resources. Prior period amounts have been recast to reflect the new segment measure for profitability.
The Company identifies the Chief Executive Officer as the CODM. In applying the criteria set forth in the standards for reporting information about segments in financial statements, we have determined that we have three reportable segments – Roofing, Insulation, and Doors. The key factors used to identify these reportable segments are the organization and alignment of our internal operations and the nature of our products. Segment EBITDA targets are established on an annual basis and used by the CODM throughout the year to compare with actual results. Quarterly forecasts supplement annual targets and provide incremental information utilized to assess the performance of a segment. Segment EBITDA variance analysis further provides insight into segment operational cost optimization.
The Company does not regularly provide significant segment expense detail to the CODM. EBITDA by segment consists of net sales less related costs and expenses, which are mainly comprised of cost of sales and marketing and administrative costs. EBITDA is presented on a basis that is used internally for evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBITDA for our reportable segments and are included within Corporate, Other and Eliminations.

About Segments Disclosures
Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.
Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
