Owens Corning Q3 2026: Resilient 20% EBITDA Margin Despite Storm-Driven Volume Collapse and Doors Impairment
Owens Corning delivered $489 million adjusted EBITDA at a 20% margin in Q3 2026 despite a $195 million revenue decline driven by the second consecutive year of below-average storm activity and a $476 million non-cash impairment charge in Doors. The Q4 outlook is materially weaker — revenue guided to $2.0–$2.2 billion with EBITDA margin of only 10–12% — as channel destocking accelerates across Roofing and inflation outpaces pricing across all three segments. The company is managing through cycle trough conditions while continuing capital investments in new Insulation capacity (Kansas City) and a new Roofing facility (Alabama, mid-2028), targeting a long-term revenue opportunity of approximately $12.5 billion with mid-20% EBITDA margins.
