Owens Corning has reported its financial results for the third quarter of 2026, revealing a 7% decrease in net sales compared to the previous year. The company attributed this decline to challenging market conditions, including weak residential demand and rising costs. Despite these challenges, Owens Corning demonstrated strong operational execution and maintained solid cash flow.

In its press release dated November 4, 2026, Owens Corning stated that it generated net sales of $2.5 billion for the quarter, a notable decrease from the prior year. The company also reported a net earnings margin of negative 10%, with an adjusted EBITDA margin of 20%. The diluted earnings per share (EPS) was $(3.15), while the adjusted diluted EPS was $2.44, excluding significant non-cash impairment charges related to its Doors Business.

The company operates within the Abrasive, Asbestos & Misc Nonmetallic Mineral Products sector, as classified under the SIC code 3290. Its headquarters is located in Toledo, Ohio.

The filing, accession number 0001370946-26-000223, reveals that despite the downturn in sales, Owens Corning produced an operating cash flow of $813 million and free cash flow of $622 million. The company also returned $337 million to shareholders through dividends and share repurchases while reducing its debt by $299 million.

Brian Chambers, Chair and Chief Executive Officer, commented on the results, stating, “During the quarter, challenging residential market conditions were further impacted by a second consecutive year of weak storm activity and rapidly rising transportation and input material costs. Despite these pressures, our team demonstrated disciplined commercial and operational execution, delivering a resilient margin and strong cash flow.” He emphasized the company’s focus on executing its strategy and leveraging its unique advantages to create long-term value for customers and shareholders.

Looking ahead, Owens Corning will likely continue to navigate these industry challenges while striving to maintain its operational effectiveness and shareholder returns.
