Owens Corning (OC) Stock Forecast & Price Target

Owens-Corning is viewed positively because its core Roofing franchise, which generates the most revenue, should benefit from stronger demand and pricing, especially if storm activity stays elevated and global economic activity improves. The company’s Insulation segment also shows constructive momentum, with net sales of $1,001 million, up 6% from 3Q25, as 5% volume growth and 1% price growth helped offset inflation and lifted EBITDA to $215 million with a 21.5% margin. Overall, the cited CY’26E Adj. EBITDA range of $2.20 BN to $2.25 BN and 9.0x EV/EBITDA assumptions indicate solid earnings power, supported by resilient U.S.-led demand and operating leverage across the portfolio.

Owens-Corning is facing a deteriorating fundamental backdrop, with 3Q26 adjusted EPS of $2.44 and adjusted EBITDA of $489 million both missing expectations, while 4Q26 guidance implies only $200 million to $264 million of EBITDA and a 10% to 12% margin, far below Street assumptions. The core issue is Roofing, where weak storm activity, distributor de-stocking, flat pricing, and rising transportation and input costs are driving a steep volume decline and margin compression, while Doors remains weak and Insulation is showing margin pressure from inflation and softer residential demand. With FY26E EPS cut to $7.71 and FY27E to $7.90, revenue and EBITDA estimates lowered, and recovery likely delayed into 1H27, earnings power appears subdued and valuation support is limited.
