2025 Enterprise Strategy Updates

•Owens Corning maintained a high level of safety performance in 2025 with a recordable incident rate (RIR) of 0.60.

•Owens Corning advanced major strategic initiatives to reshape the company as a focused building products leader in North America and Europe. The company completed the sale of its building materials business in China and Korea, and completed the strategic review and announced the sale of its glass reinforcements business. This transaction continues to progress through regulatory approvals and is targeted for completion in the next few months.

•By advancing the strategic integration of its Doors business and applying Owens Corning's proven commercial and operational playbook to unlock value, the company is exceeding the $125 million of enterprise run-rate cost synergies committed to by mid-2026. The company is also on track to deliver an additional $75 million of structural cost improvements through network optimization and operational efficiencies, including the closure and consolidation of five facilities in 2025 and the recent sale of a small distribution business to a major customer.

•Owens Corning continues to make targeted investments to enhance the efficiency of its manufacturing network and support future growth. The company brought key investments online in its Roofing and Insulation businesses in 2025. In addition, Owens Corning announced significant investments across both businesses, which will modernize assets, increase operating efficiencies, and strengthen market-leading positions as these investments come online over the next few years.

Cash Returned to Shareholders

•Owens Corning returned $1.0 billion to shareholders through cash dividends and share repurchases in 2025, supporting its commitment to return $2.0 billion of cash to shareholders by the end of 2026. The company paid cash dividends of $232 million and repurchased 5.9 million shares of common stock for $770 million. Over the past five years, the company has repurchased 29 million shares of common stock for $3.2 billion. At the end of 2025, 12.5 million shares were available for repurchase under the current authorizations.

•In December 2025, Owens Corning announced that its Board of Directors declared a quarterly cash dividend of $0.79 per common share, a 15% increase compared with the associated prior quarterly dividends. This increase reflects the 12th consecutive year of dividend growth for Owens Corning and triples the per share payout compared to five years ago.

“Owens Corning delivered $1.8 billion of operating cash flow and returned $1 billion of cash to shareholders with EBITDA margins above 20% in a year of weaker market conditions,” said Executive Vice President and Chief Financial Officer Todd Fister. “While the challenging end markets in Doors resulted in a non-cash impairment charge, we continue to be confident in the long-term earnings potential of the business. Moving forward, we remain focused on improving the margins and cash flows of our businesses as markets improve later this year."

Other Notable Highlights

•Owens Corning has been named to the Wall Street Journal's list of top 250 Best-Managed Companies. The list ranks companies based on principles of corporate effectiveness including customer satisfaction, employee engagement, innovation, social responsibility, and financial strength. Owens Corning placed 10th in customer satisfaction among those recognized.

Business Performance from Continuing Operations

Full-Year

•Owens Corning delivered an adjusted EBITDA margin of 22% despite operating in more challenging market conditions as the year progressed. This reflects the company's structural cost improvements, favorable product mix shifts, and strong market positions.

First-Quarter and Full-Year 2026 Outlook for Continuing Operations

•The key economic factors that impact the company’s business are residential repair activity, residential remodeling activity, U.S. housing starts, and commercial construction activity.

•Owens Corning expects residential new construction and discretionary remodeling to remain challenged as the year begins, reflecting lower lagged single-family housing starts and continued cautious purchasing behavior. Within roofing, the company expects to see weaker manufacturer shipments reflecting lower storm carryover demand and lower restocking activity. Non-residential construction activity in North America is expected to be relatively stable versus prior year, and market conditions in Europe are anticipated to gradually improve throughout the year with currency tailwinds.

•Owens Corning expects minimal first-quarter impact from tariff exposure as a result of long-term and short-term mitigation efforts, based on current tariff policies. In the first quarter, the company anticipates the net impact of tariff exposure to be about $10 million.

•For the first-quarter 2026, Owens Corning expects to continue delivering strong financial performance in a challenging market environment based on structural improvements made to the company and its market-leading positions. Revenue from continuing operations is expected to be approximately $2.1 billion to $2.2 billion. The company expects to generate enterprise adjusted EBITDA margin from continuing operations in the mid-teens. It expects to realize the impact of higher cost inventory flowing through the P&L in the first quarter based on higher fourth-quarter down times taken to manage inventories.

•For the full year, the company expects to see market improvement as the year progresses resulting in top and bottom-line results largely aligned with current consensus estimates.

•Owens Corning remains committed to delivering the long-term targets provided at its 2025 Investor Day, including revenue growth, an annual adjusted EBITDA margin of mid-20% for the enterprise, and $5 billion of cumulative free cash flow by 2028.

Current 2026 Financial Outlook for Continuing Operations


General Corporate EBITDA Expenses			$245 million to $255 million
Interest Expense			$255 million to $265 million
Effective Tax Rate on Adjusted Earnings			24% to 26%

Capital Additions			Approximately $800 million
Depreciation and Amortization			Approximately $680 million

Use of Non-GAAP Measures

Owens Corning uses non-GAAP measures in its earnings press release that are intended to supplement investors' understanding of the company's financial information. These non-GAAP measures include EBITDA from continuing operations, adjusted EBITDA from continuing operations, adjusted earnings from continuing operations, adjusted diluted earnings per share attributable to Owens Corning common stockholders ("adjusted EPS") from continuing operations, adjusted pre-tax earnings from continuing operations, and free cash flow. When used to report historical financial information, reconciliations of these non-GAAP measures to the corresponding GAAP measures are included in the financial tables of this press release. Specifically, see Table 2 for adjusted EBITDA from continuing operations, Table 3 for adjusted earnings from continuing operations and adjusted EPS from continuing operations, and Table 8 for free cash flow.

For purposes of internal review of Owens Corning's year-over-year operational performance, management excludes from net earnings attributable to Owens Corning certain items it believes are not representative of ongoing operations. The non-GAAP financial measures resulting from these adjustments (including adjusted EBITDA from continuing operations, adjusted earnings from continuing operations, adjusted EPS from continuing operations, and adjusted pre-tax earnings from continuing operations) are used internally by Owens Corning for various purposes, including reporting results of operations to the Board of Directors, analysis of performance, and related employee compensation measures. Management believes that these adjustments result in a measure that provides a useful representation of its operational performance; however, the adjusted measures should not be considered in isolation or as a substitute for net earnings attributable to Owens Corning as prepared in accordance with GAAP.

Free cash flow is a non-GAAP liquidity measure used by investors, financial analysts and management to help evaluate the company's ability to generate cash to pursue opportunities that enhance shareholder value. The company defines free cash flow as net cash flow provided by operating activities, less cash paid for property, plant and equipment. Free cash flow is not a measure of residual cash flow available for discretionary expenditures due to the company's mandatory debt service requirements. Free cash flow is used internally by the company for various purposes, including reporting results of operations to the Board of Directors of the company and analysis of performance.

Management believes that these measures provide a useful representation of our operational performance and liquidity; however, the measures should not be considered in isolation or as a substitute for net cash flow provided by operating activities or net earnings attributable to Owens Corning as prepared in accordance with GAAP.

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.
