The Insulation segment saw a 7% Y/Y decline in sales to $941 million, generating $212 million in EBITDA at a 23% margin. Sales declined due to lower sales volume (-5% Y/Y) and the unfavorable impact from the divestiture of its building materials business in China and Korea.

Management Commentary

“Our third-quarter financial results continue to demonstrate our ability to perform at a high level even in the face of challenging market conditions, as we see weakening residential demand trends in the U.S. impacting our volumes in both repair and remodel and new construction product lines,” commented Chair and Chief Executive Officer Brian Chambers.

Outlook

Owens Corning ( OC ) expects minimal impact from tariffs in the fourth quarter. In the fourth quarter, the company anticipates reducing its approximately $50 million tariff exposure to a net impact of about $10 million, primarily in the Doors business.

Revenue from continuing operations is projected to decline mid-to-high teens, around $2.10 billion and $2.20 billion, compared to the $2.463 billion analyst estimate.

The company expects adjusted EBITDA margins from continuing operations of 16%–18% in the quarter.

Owens Corning ( OC ) continues to aim for revenue growth, a mid-20% annual adjusted EBITDA margin, and $5 billion cumulative free cash flow by 2028.

The company expects continued challenges in residential new construction and remodeling due to softer market conditions and year-end inventory reductions affecting all three business segments.

Demand for essential roofing repairs is expected to drop notably in the fourth quarter on reduced storm activity and lower distribution inventories.

Also, the company projects non-residential construction in North America to decline slightly, while market conditions in Europe are expected to improve gradually.

Price Action: OC shares were trading lower by 2.37% to $119.81 premarket at last check Wednesday.
