Owens Corning NYSE: OC reported a third-quarter net loss after recording a $476 million non-cash impairment in its Doors business, as weak storm activity, softer residential demand and rising costs weighed on results.

The building products company reported revenue of $2.5 billion, down $195 million from a year earlier. Adjusted EBITDA was $489 million, or 20% of revenue, and adjusted diluted earnings per share were $2.44. Free cash flow was $622 million.

Chief Financial Officer Jonathan Collins said lower roofing volumes and softer Doors demand were partly offset by growth in insulation. The impairment reflected softer market conditions and continued inflation and affected the remaining goodwill from the Masonite acquisition, he said.

Chair and Chief Executive Officer Brian Chambers said the company had expected a stronger market, including storm activity closer to historical averages. Instead, it faced a second consecutive year of weak storm activity alongside rapidly rising transportation and material costs.

Fourth-quarter outlook reflects weaker demand

Owens Corning expects fourth-quarter revenue of $2 billion to $2.2 billion and an adjusted EBITDA margin of approximately 10% to 12%. Chief Operating Officer Todd Fister said the outlook reflects higher inflation and transportation costs, seasonal factors and additional production downtime as the company adjusts to weaker volumes.

Collins said the company expects a year-over-year inflation impact of more than $100 million in the fourth quarter, comparable to the third quarter. Owens Corning has surcharges in place, but its ability to raise prices in the near term is limited, he said.

For roofing, the company expects revenue to decline by a high-single-digit percentage from a year earlier and EBITDA margin to be 18% to 20%. Fister said industry shipments measured by the Asphalt Roofing Manufacturers Association, or ARMA, are expected to fall by a high-teen percentage as distributors reduce inventories.

Chambers said the company’s outlook implies an approximately 10% decline in full-year ARMA shipments. He estimated that roughly half of the decline was tied to weather, with the remainder attributable to weaker demand and destocking. He said the company expects distributors to reduce inventories more heavily in the fourth quarter than a year earlier.

Some effects of production downtime could also carry into early 2027 as higher-cost inventory is sold, Chambers said. He said inflation and an expectation of improved demand have historically created conditions for a spring roofing price increase, but did not announce one.

Insulation grows as Doors and roofing decline

Roofing: Third-quarter sales topped $1 billion, down 16% from a year earlier, while EBITDA fell $124 million to $299 million. The segment posted a 29% EBITDA margin despite lower volumes and higher costs. ARMA shipments declined 13% in the quarter.

Insulation: Sales rose 6% to $1 billion, supported by North American non-residential and European markets. EBITDA increased slightly to $215 million, for a 21% margin. The company expects fourth-quarter revenue to rise by a mid-single-digit percentage and EBITDA margin to be in the high teens.

Fister said demand for non-residential insulation has benefited from areas including data centers and U.S. re-industrialization. The company is sold out in its mineral wool and fiberglass pipe businesses, limiting near-term volume growth in those products. A new Kansas City fiberglass line is expected to add capacity in the second half of 2027.

Doors: Sales declined 11% to $483 million, and EBITDA was $25 million, representing a 5% margin. Collins said the sale of the distribution business and an Oregon components facility accounted for about half of the revenue decline. For the fourth quarter, Owens Corning expects Doors revenue to fall by a mid-single-digit percentage and its EBITDA margin to be in the low single digits. A previously announced interior Doors price increase is scheduled for January.

Debt reduction takes priority

Owens Corning returned $337 million to shareholders through dividends and repurchases during the quarter. Collins said the company repaid $400 million of maturing bonds using cash and commercial paper borrowings, resulting in a debt reduction of nearly $300 million.

The company has completed the vast majority of its $2 billion shareholder return commitment for 2025 and 2026, but now expects to complete the remainder in 2027 as it prioritizes debt reduction. It ended the quarter with $1.6 billion in liquidity and net leverage of 2.5 times, within its target range, Collins said.

Fister said Owens Corning continues to see the potential for approximately $12.5 billion in revenue, mid-20% EBITDA margins and at least $1.5 billion in annual free cash flow in better markets. He declined to provide a 2027 forecast, saying results would depend significantly on market conditions.
