Owens Corning (OC) Stock Price & How to Invest

Short answer
Owens Corning (NYSE: OC) is a residential building products maker with three segments, Roofing, Insulation and Doors, where roofing shingle replacement supplies most of the profit and the 2024 Masonite doors deal supplied a ~$1,135 million goodwill write-off. Someone investing would hold the common stock directly or size it inside a housing, building-products or homebuilding-adjacent theme alongside peers such as Mohawk, Fortune Brands and Carlisle.

What does Owens Corning (OC) do?
Owens Corning sells three things that go into houses: asphalt roofing shingles, insulation, and doors. Founded in 1938 and headquartered in Toledo, Ohio, it files with the SEC under the plain name Owens Corning, with no Inc. or Corp. attached. Roofing is the biggest and most profitable segment, at ~$1,313 million of second-quarter 2026 sales on a ~34% EBITDA margin, and most of that volume is replacement work: shingles age, storms strip them, and the homeowner reroofs whether or not housing starts are healthy. Insulation, ~$971 million in the quarter, spans fiberglass batts, loose fill, foam sheathing and European stone wool from the Paroc business, and reaches non-residential jobs as well as homes. Doors, ~$513 million, is the Masonite business bought in May 2024. On April 30, 2026 the company closed the sale of its global glass reinforcements operation, retiring the last of the old Composites segment.
The reported numbers look far worse than the operating ones, and the difference matters. Continuing operations earned ~$310 million in the second quarter on ~$2.76 billion of sales, with adjusted EPS of ~$3.93, while the trailing twelve months carry a GAAP net loss of ~$671 million because glass reinforcements sat in discontinued operations at a markdown and Doors absorbed a ~$1,135 million goodwill impairment plus a ~$39 million tradename write-down in 2025. That write-off frames the argument: Owens Corning announced Masonite at ~$3.9 billion, closed it for ~$3.2 billion, then erased most of the goodwill within eighteen months while Doors sales slipped to ~$513 million from ~$554 million. Management's answer has been cost, with ~$135 million of run-rate synergies delivered against a ~$125 million commitment. The shares change hands near ~$151 for a ~$11.9 billion market cap, about ~1.2x sales, against ~$4.9 billion of net debt and a pledge to return ~$2 billion to shareholders across 2025 and 2026.
What's driving Owens Corning (OC)?
1. Roofing runs on replacement, not on housing starts
Roofing produced ~$1,313 million of second-quarter 2026 sales and ~$441 million of EBITDA, a ~34% margin that no other Owens Corning segment approaches. Demand comes overwhelmingly from re-roofing an existing house after hail, wind or simple shingle age, which is why the segment held flat against the prior year while new residential construction stayed soft. The company guided third-quarter storm demand to historical averages and flagged that heavy second-quarter distributor stocking will pull some purchases out of the third quarter.
2. The portfolio was deliberately narrowed to residential
The glass reinforcements business, the last remnant of the old Composites segment, was sold on April 30, 2026 for ~$370 million net of cash divested, well below the ~$436 million originally agreed in February 2025 after an April 2026 amendment cut the price by ~$110 million and removed ~$225 million of contemplated seller financing. What remains is a North America and Europe residential building products company with three segments and no industrial glass fiber exposure.
3. Doors is the open question, and cost is the answer being tried
Doors sales fell to ~$513 million from ~$554 million year over year and segment EBITDA margin compressed to ~11% from ~14%. Against that, the company reports ~$135 million of run-rate enterprise cost synergies, above the ~$125 million it had promised by mid-2026, with a further ~$75 million targeted from network optimization. Whether structural cost work can carry a segment whose revenue keeps shrinking is the central debate on the stock.
4. Cash goes back to holders while the balance sheet stays loaded
Owens Corning returned ~$264 million in the second quarter, ~$200 million of buybacks at 1.7 million shares plus a ~$64 million dividend, inside a ~$2 billion commitment spanning 2025 and 2026. It also plans ~$800 million of capital additions and ~$255 million to ~$265 million of interest expense this year, against ~$5.1 billion of total debt and ~$271 million of cash. Free cash flow was ~$199 million in the quarter and negative ~$188 million for the half.
What are the risks to Owens Corning (OC)?
Roofing demand is weather-dependent, so a mild storm season removes volume from the segment that generates most of the profit, and the company already warned that second-quarter distributor stocking borrows from the third quarter. Input costs are exposed on two fronts, asphalt tied to crude and refinery output for shingles and energy for glass melting furnaces, and management quantified roughly $40 million of incremental third-quarter cost from inflation tied to the Iran conflict. Doors still carries ~$367 million of goodwill and the company holds ~$1,196 million of indefinite-lived trademarks, so a further deterioration in that business could produce another non-cash write-down after the ~$1,135 million already taken. Net debt of roughly ~$4.9 billion against a ~$11.9 billion market cap leaves less cushion than the company carried before the Masonite deal. Separately, the Paroc subsidiary withdrew marine insulation products over fire safety certification nonconformances and suspended sales of certain ventilation duct and steel beam insulation products, where the 10-Q states the potential loss cannot yet be reasonably estimated.

Is OC a buy or a sell?
We give no verdict on Owens Corning. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.
The case for buying. Roofing runs on replacement, not on housing starts. Roofing produced ~$1,313 million of second-quarter 2026 sales and ~$441 million of EBITDA, a ~34% margin that no other Owens Corning segment approaches. The most optimistic published target, $198.00, assumes this works close to its best case.
The case against. Roofing demand is weather-dependent, so a mild storm season removes volume from the segment that generates most of the profit, and the company already warned that second-quarter distributor stocking borrows from the third quarter. The most pessimistic target, $140.00, is roughly what OC is worth if this bites instead.

How is Owens Corning (OC) valued? (approximate, August 2026)
A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Owens Corning's investor relations page or your broker.
- Revenue (TTM, continuing operations): ~$9.85 billion
- Q2 2026 net sales: ~$2.76 billion, roughly flat vs ~$2.75 billion
- Q2 2026 adjusted EPS (continuing ops): ~$3.93 vs ~$4.21 a year earlier
- Net loss (TTM, GAAP, incl. discontinued ops): ~-$671 million, or ~-$8.23 per share
- Market cap: ~$11.9 billion at ~$151 per share, about ~1.2x sales
- Net debt: ~$4.9 billion (~$5.1 billion debt, ~$271 million cash)
The headline loss is an accounting artifact of two decisions rather than a description of current trading: the glass reinforcements sale was carried through discontinued operations at a pre-tax loss of ~$175 million for the first half, and Doors took ~$1,135 million of goodwill impairment plus ~$39 million of tradename impairment during 2025. Continuing operations produced ~$660 million of adjusted EBITDA on a ~24% margin in the quarter. Third-quarter guidance calls for ~$2.6 billion to ~$2.7 billion of revenue at a ~20% to ~22% adjusted EBITDA margin, and the quarterly dividend annualizes to roughly ~$3.16 per share, about a ~2.1% yield at recent prices.
Which ETFs hold Owens Corning (OC)?
Who competes with Owens Corning (OC)?
Residential roofing
GAF, owned by Standard Industries, is the largest US asphalt shingle maker and Owens Corning's closest direct rival, with TAMKO, IKO and Saint-Gobain's CertainTeed also competing on shelf space at distributors. Among listed names, Carlisle Companies (CSL) overlaps in roofing but skews commercial, while Beacon and other distributors sit between the shingle plants and the contractor.
Insulation
Knauf Insulation, Johns Manville (a Berkshire Hathaway subsidiary), Denmark's Rockwool and Ireland's Kingspan (KRX) contest the same fiberglass, stone wool and foam categories, with Saint-Gobain present through CertainTeed. TopBuild (BLD) and Installed Building Products (IBP) buy and install insulation rather than make it, so they read as demand indicators as much as competitors.
Doors and broader building products
JELD-WEN (JELD) is the most direct listed doors comparison, with Fortune Brands Innovations (FBIN) competing through Therma-Tru entry doors and privately held Andersen and Pella overlapping in openings. For portfolio purposes, Mohawk Industries (MHK), Louisiana-Pacific (LPX), James Hardie (JHX) and Builders FirstSource (BLDR) share the same US housing repair and remodel cycle.

FAQ
What does Owens Corning do?
+
Owens Corning manufactures residential building products in three segments. Roofing makes asphalt shingles, oxidized asphalt, roofing components and glass mat. Insulation makes fiberglass batts, loose fill, spray foam, foam sheathing and stone wool. Doors, added through the 2024 Masonite purchase, makes interior and exterior doors and door systems. Sales are concentrated in North America, with a meaningful European insulation and doors presence.
How does Owens Corning make money?
+
It sells manufactured products through distributors, big box retailers, builders and contractors, and earns a spread between selling price and the cost of asphalt, glass batch materials, energy and freight. Roofing carries by far the richest economics, at a ~34% EBITDA margin in the second quarter of 2026 versus ~22% in Insulation and ~11% in Doors, so replacement roofing supplies a disproportionate share of profit.
What is the full legal name of the company that trades as OC?
+
The registrant is simply Owens Corning, a Delaware corporation, with no Inc., Corp. or Company suffix in its SEC filings. Its CIK is 0001370946 and it lists on the New York Stock Exchange under the ticker OC, with headquarters at One Owens Corning Parkway in Toledo, Ohio. The current entity emerged in 2006 from the reorganization of the older Owens-Corning Fiberglas business.
What did Owens Corning report most recently?
+
Second-quarter 2026 results, released August 5, 2026, showed net sales from continuing operations of ~$2,756 million, essentially level with ~$2,747 million a year earlier. Net earnings from continuing operations were ~$310 million, diluted EPS from continuing operations ~$3.84 and adjusted diluted EPS ~$3.93. Adjusted EBITDA was ~$660 million at a ~24% margin. Free cash flow for the quarter came to ~$199 million.
Why does Owens Corning show a large loss if the business is profitable?
+
Two non-operating items sit in the trailing figures. The Doors reporting unit absorbed ~$1,135 million of goodwill impairment and ~$39 million of tradename impairment during 2025, and the glass reinforcements divestiture ran through discontinued operations, including a ~$175 million pre-tax loss in the first half of 2026 after the price was cut. Continuing operations remained profitable throughout.
Does Owens Corning pay a dividend?
+
Yes. The company paid ~$64 million of quarterly dividends in the second quarter of 2026, which annualizes to roughly ~$3.16 per share and works out near a ~2.1% yield at a ~$151 share price. Buybacks are the larger channel: ~$200 million and 1.7 million shares in the quarter, inside a stated ~$2 billion of total shareholder returns across 2025 and 2026.
What is Owens Corning worth relative to earnings?
+
At roughly ~$11.9 billion of market capitalization on ~$9.85 billion of trailing continuing-operations revenue, the shares trade near ~1.2x sales. A trailing price to earnings ratio is not meaningful because GAAP earnings are negative on the impairments, so the valuation debate usually runs on adjusted EPS, which was ~$5.15 for the first half, and on enterprise value against adjusted EBITDA including the ~$4.9 billion of net debt.
How would someone invest in Owens Corning?
+
OC trades on the NYSE and can be bought as ordinary common stock through any US brokerage, in whole or fractional shares. Some holders prefer to size it inside a housing and building products theme rather than alone, pairing it with names such as Mohawk, Fortune Brands, Louisiana-Pacific or Builders FirstSource so that a single storm season or one segment does not drive the whole position.
