Overview
ACCE thesis
Owens Corning makes glass fiber reinforcement, roofing shingles and foam insulation, selling much of its roofing and insulation output through a large residential re-roofing and repair channel rather than new construction alone. Its moat rests on scale in fiberglass reinforcements and a brand-backed installer network that is hard for smaller rivals to copy. The stock trades at about 10x forward earnings against an 18% operating margin, which is a reasonable multiple for a business of this quality if margins hold. Revenue growth is essentially flat at 0.3%, and a negative 9.4% ROE means the return on shareholder equity is currently poor, so the case depends on whether volume recovery in roofing and insulation lifts earnings from here. The score of 39/100 and absence from major indices suggest the market is not yet paying for a turnaround, which makes this worth a deeper look on the earnings trajectory rather than a conclusion.
⚠ Investor warnings · 3 flagsAI-assisted·How I use AI
high
Earnings down sharply
Earnings fell 34.2% year over year while revenue grew only 0.3%. Net margin is -6.8% and ROE is -9.4%, so the business is currently loss-making on a net basis.
high
Leverage elevated
Debt/Equity is 1.60. Despite $962M of free cash flow, that leverage leaves less room to absorb a further earnings decline.
moderate
ACCE score collapse
The ACCE score dropped 18 points in 90 days, from 57 to 39, with growth scored 19 and quality 38, the weakest components.

Why it could do well
The stock trades on a forward P/E of 10.1x and a free cash flow yield of 10.7%, a low price for the cash it generates.
Free cash flow over the last twelve months reached $962M, giving the company real cash to pay down debt and return to shareholders.
Analysts' mean price target of $161.56 sits 43.5% above the share price, and 11 of 18 analysts rate the stock Buy or Strong Buy.
Why it could disappoint
Net margin of -6.8% and return on equity of -9.4% show the company is currently losing money on its sales and shareholder capital.
Revenue grew just 0.3% year over year, well below the 7.4% average annual growth over the past five years.
Debt equals 1.60 times shareholder equity, a heavy load that leaves less room to absorb a further downturn in earnings.
