FORWARD-LOOKING STATEMENTS AND NON-GAAP MEASURES This presentation and the associated remarks contain forward-looking statements. We caution you against relying on these statements as they are subject to risks, uncertainties and other factors and actual results may differ materially from those results projected in the statements. These risks, uncertainties and other factors include, without limitation: levels of residential and non-residential construction activity; demand for our products; industry and economic conditions including, but not limited to, supply chain disruptions, recessionary conditions, inflationary pressures, and interest rate and financial market s volatility; additional changes to tariff, trade or investment policies or laws by the United States, or similar actions, including reciprocal actions, by foreign governments; availability and cost of energy and raw materials; competitive and pricing factors; relationships with key customers and customer concentration in certain areas; our ability to achieve expected synergies, cost reductions and/or productivity improvements; issues related to acquisitions, divestitures and joint ventures or expansio ns; climate change, weather conditions and storm activity; legislation and related regulations or interpretations in the United States or elsewhere; domestic and in ternational economic and political conditions, policies or other governmental actions, as well as war and civil disturbance; uninsured losses or major manufacturing disruptions, including those from natural disasters, catastrophes, pandemics, theft or sabotage; environmental, product-related or other legal and regulatory liabilities, proceedings or actions; research and development activities and intellectual property protection; issues involving implementation and protection of informatio n technology systems; foreign exchange and commodity price fluctuations; our level of indebtedness; our liquidity and the availability and cost of credit; the level of fixed costs required to run our business; levels of goodwill or other indefinite-lived intangible assets; loss of key employees and labor disputes or shortages; defined benefit plan funding obligations; and factors detailed from time to time in the company’s filings with the U.S. Securities and Exchange Commission. This information speaks as of November 4, 2026, and is subject to change. The company does not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by federal securities laws. The terms “year to date” or last twelve months (“LTM”) refer to the period ended on the last calendar day of the quarter preceding the date of the investor event referenced on the first page above. Otherwise, the information in this presentation speaks as of the date of the investor event and is subject to change. The Company assumes no obligation to update or revise forward-looking statements except as required by law. Any distribution of this presentation after the investor event is not intended and should not be construed as updating or confirming such information. This presentation contains references to certain "non-GAAP financial measures" as defined by the SEC, which may be referenced in the Appendix or in the tables of our earnings press release. Adjusted EBITDA from continuing operations, adjusted earnings from continuing operations, adjusted diluted EPS from continuing operations, and return on capital from continuing operations are measures management uses to evaluate the profitability and operating performance of the business. Free cash flow is a measure management uses to evaluate cash generation and capital deployment performance. Net debt and net leverage are non-GAAP financial measures that management uses to assess liquidity, financial flexibility and leverage. The company defines net debt as total debt less cash and cash equivalents. The company defines net leverage as net debt divided by adjusted EBITDA from continuing operations for the LTM. These measures exclude certain items that management does not allocate to its segment results because it believes they are not representative of the company’s ongoing operations. Reco nciliations of these non-GAAP measures to the most directly comparable GAAP measures are included in the Appendix and, where applicable, in the tables of our earnings press release. When the company provides forward-looking expectations for non-GAAP measures, the most comparable GAAP measures and a reconciliation between the non-GAAP expectations and the corresponding GAAP measures are generally not available without unreasonable effort due to the variability, complexity and limited visibility of the adjusting items that would be excluded from the non-GAAP measures in future periods. The variability in timing and amount of adjusting items could have significant and unpredictable effect on our future GAAP results. 3 THE PINK PANTHER & © 1964-2026 Metro-Goldwyn-Mayer Studios Inc.

11 The above outlook reflects a year-over-year comparison to Q4 2025 results for continuing operations Full-year 2026 key financial outlook for continuing operations: general corporate EBITDA expenses of $235mm - $245mm, interest expense of $255mm - $265mm, full-year effective tax rate of 24% - 26% (cash taxes anticipated to be lower), capital additions of approximately $800mm, depreciation and amortization of approximately $680mm Q4 2026 BUSINESS OUTLOOK ROOFING • Revenue down high-single digits • Industry shipments for U.S. end-market demand down high teens with OC volumes above the market • Continued strong components attachment • Price expected to be relatively flat with ongoing input cost and transportation inflation, resulting in negative price/cost • Downtime costs due to lower demand • EBITDA margin in the range of 18% to 20% INSULATION DOORS • Revenue up mid-single digits • NA residential revenue down low single digits; targeted price moves and slightly lower volumes • NA non-residential revenue up low teens; volume growth and positive pricing • Europe revenue up; stable volumes and positive pricing • Input cost and transportation inflation drive negative price/cost, partially offset by positive manufacturing performance • EBITDA margin in the high teens • Revenue down mid-single digits • Revenue decline driven by the divestiture of distribution business and lower volumes • Pricing expected to be modestly positive • Continued input cost and transportation inflation, resulting in negative price/cost • Higher manufacturing costs, including downtime • EBITDA margin of low-single digits ENTERPRISE: • Revenue of $2.0b to $2.2b • NA residential remains under pressure; NA non-residential continues to see pockets of strength; Europe stable • Second consecutive year without significant storm activity and distribution destocking expected to weigh on roofing demand • Significantly higher inflation and transportation costs with incremental downtime due to weaker market volumes • Adjusted EBITDA margin of approximately 10% to 12%

16 APPENDIX A: NON-GAAP RECONCILIATIONS – TABLE 3 (a) Management excludes from Net earnings from continuing operations attributable to Owens Corning certain items it believes are not representative of ongoing operations. Please refer to Table 1 of Appendix A for explanation of adjusting items. (b) To compute adjusted earnings from continuing operations, we apply a full year pro forma effective tax rate to each quarter presented. The pro forma tax rate is equal to each year's effective tax rate, excluding the tax impact of adjusting items referenced in (a), and excluding the impact of significant tax items. For 2026, we used a full year pro forma effective tax rate of 25%, which is the mid-point of our 2026 effective tax rate guidance of 24% to 26%. There were no significant tax items in the first nine months of 2026. For comparability, in 2025, we have used an effective tax rate of 25% which was our 2025 effective tax rate, excluding the adjusting items referenced in (a). The taxes at pro forma tax rate are applied to adjusted EBITDA from continuing operations after deducting depreciation and amortization expense. (c) To remove the impact of accelerated depreciation and amortization charges for restructuring projects and impairments which are excluded from adjusted earnings from continuing operations.
