Our note on each quarter Owens Corning files

Where Owens Corning stands after its latest 10-Q

Revenue for the twelve months to June 2026 was $9.85bn, down 7.2% on a year earlier, slower than -5.1% a quarter earlier. That puts it 907 of 931 for growth among all the companies we cover. Free-cash-flow margin held at 9.1%. Operating margin narrowed to 0.5% from 15.1%. The diluted share count is down 6.1% on a year earlier, which lifts each remaining share. Against its peers on growth, profitability, cash generation and balance sheet, it grades D. It passes 2 of our 7 financial-health checks. At that price, our model says the market is pricing in cash flow shrinking about 2.6% a year for five years, slower than the 3.0% a year revenue growth it has delivered.

Our model value for Owens Corning is under review, so past values are not shown until it is resolved.

The Fundamentalytics view

Next results ~November 4, 2026 (estimated)

Owens Corning's trailing-twelve-month revenue fell 7.2% year on year, with a free-cash-flow margin of 9.1%. Where it stands out: change in share count of -6.1% ranks 3 of 44 building products companies we cover. Where it lags: revenue growth of -7.2% ranks 38 of 46 building products companies we cover.

Our discounted-cash-flow model values the business at ~$200 per share in the base case (~$140–$290 across growth scenarios) — model values under stated assumptions, not a price target.

Current signal Revenue growth decelerating: TTM revenue growth slowed to -7.2% (-2.2pp vs the prior quarter), the 4th consecutive quarterly slowdown.

Assembled from SEC-filed figures — the full workings are on this page and in our methodology. Observations, not recommendations.

Moat

48 /100

Moderate moat

How hard Owens Corning's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 6 / 20

    Net income has been a median 4.8% of total assets over 10 years.

  • Pricing power 9 / 20

    Gross margin has been a median 25.7%, moving by 3.0 percentage points (standard deviation) across 10 years.

  • Durability 4 / 20

    Operating margin has been a median 15.1%; its worst year was -3.8%.

  • Cash conversion 15 / 20

    Free cash flow was positive in 10 of 10 years, at a median 9.5% of revenue.

  • Discipline 20 / 20

    The diluted share count fell 23.9% over five years; stock-based pay has been a median 0.7% of revenue.

AI disruption exposure: Medium. In this industry, AI could change how the product is made or sold, without replacing the core asset. The score above includes a 5-point deduction for that exposure (53 before it).

Free cash flow is cash from operations minus capital spending. Growth is left blank when last year's figure was a loss or under 2% of revenue. Share counts and EPS are restated for stock splits. A dash means the company didn't report the figure.
