Owens Corning Q3 2026 Earnings Recap

Owens Corning’s shares rose 8.5% after earnings, with investors apparently responding to $489 million of adjusted EBITDA, a 20% margin and $622 million of free cash flow despite weaker-than-expected market conditions. The quarter also had clear headwinds: storm activity fell short of the company’s outlook assumptions, while transportation and input costs rose.

Key Takeaways

• Revenue was $2.5 billion; adjusted EBITDA was $489 million, with a 20% adjusted EBITDA margin.
• Free cash flow reached $622 million, above the company’s third-quarter average for the prior five years. Owens Corning returned $337 million to shareholders through dividends and share repurchases.
• Residential markets remained challenging, and storm activity was weaker than the company had assumed; rapidly rising transportation and input-material costs added pressure.
• Roofing performance was supported by contractor engagement, mix shift toward higher-value laminate shingles and growth in components. In Insulation, the company cited opportunities in nonresidential and European markets, while residential remained under pressure.
• Doors performance continued to face soft demand, inflation and tariffs, which management said were masking progress from its integrated go-to-market strategy.
