Owens Corning reports 7% decline in sales, adjusted EPS also below expectations

Owens Corning ($OC) reported third-quarter 2026 revenue of $2.489 billion, down 7% year over year from $2.684 billion and about $130 million below consensus, while adjusted EPS fell to $2.44 from $3.67 a year earlier and missed estimates by $0.61. GAAP diluted EPS from continuing operations came in at a loss of $3.15. The revenue and earnings shortfall matters because it signals weakening demand and margin pressure in the company's core building products segments, with the door business among the areas in focus. Investors will watch next for management commentary on the door segment and any update to full-year guidance.
