Owens Corning (OC) Stock Forecast & Price Target

Owens-Corning is well positioned for fundamental upside because roofing, its largest segment, is benefiting from strong price realization, a second price increase, and continued contractor network expansion in a market where it serves about 30,000 contractors versus an estimated 100,000+ in the U.S. roofing market. The company’s results were above the Street, helped by a roofing pre-buy ahead of price increases, while 2Q26 roofing guidance was notably flattish instead of showing the expected pressure, and management sees roofing normalizing on the horizon. On a forward basis, CY’26E Adj. EBITDA of $2.20 BN and 2026 EBITDA estimates raised to $1,848 million, along with sequential EBITDA margin improvement in Doors to high single digits, support a constructive outlook.

Owens-Corning is facing a negative fundamental setup because its core Roofing, Insulation, and Doors segments are all showing volume pressure, margin contraction, and weaker pricing, with 1Q26 sales down 10% to $2,265 million and EBITDA down 35% to $369 million. Roofing, its largest segment, saw sales fall 14% and EBITDA decline 30%, while Insulation and Doors also posted lower revenue and profitability, suggesting limited operating leverage amid softer housing demand and persistent cost inflation. Although the business still generates strong FCF and supports buybacks, near-term earnings growth appears constrained by weaker U.S. housing, slow global GDP growth, and a valuation that is likely to remain compressed versus peers.
