Owens Corning forecast third-quarter 2026 revenue between $2.6 billion and $2.7 billion, with adjusted EBITDA margins expected to land between 20% and 22%, the company said in its earnings announcement on August 5.
The revenue range represents a midpoint of $2.65 billion, a 1.9 percent increase from the top end of the prior quarter's guidance. The adjusted EBITDA margin guidance of 20 percent to 22 percent assumes margins hold or expand within the $100 million revenue range provided.
Owens Corning is a diversified building materials manufacturer with three reportable segments: roofing, composites, and insulation. The company operates across residential and commercial construction channels. The Q3 guidance follows what the company described as a strong second quarter, with shares rising 3 percent on earnings beat that day.
For a midpoint revenue of $2.65 billion, a 21 percent margin would yield approximately $557 million in adjusted EBITDA. The prior quarter's margin performance was not disclosed in the announcement reviewed, making direct period-over-period comparison unavailable from the guidance alone.
Housing starts and residential construction have remained volatile through 2026, while commercial activity has held steadier. The company's composite business, which serves aerospace and industrial customers, operates outside the housing-sensitive insulation and roofing segments.
The third quarter spans July through September, a seasonal period that typically captures late-summer residential projects and the tail of renovation cycles before fall weather constraints. Q3 2026 results and actual margin performance will become available when the company reports in late October.
Owens Corning's narrow guidance range and specified margin floor tie management compensation and investor expectations tightly to operational delivery. If Q3 revenue falls below $2.6 billion or adjusted EBITDA margins contract below 20 percent, the miss would require management comment on demand or cost pressures.
