Grade
C62Owens Corning is a market-leading building-products franchise whose headline loss stems from a large non-cash Doors goodwill impairment, not operating distress.
Strengths
- Market leader in roofing/insulation with strong operating cash margin (71.9th pct) and ~$2.27B adjusted EBITDA
- Active portfolio reshaping (GR divestiture, Masonite) and ongoing share repurchases
Risks
- Net loss (-5.2% margin) and negative ROE/ROA driven by $1.135B Doors impairment, with further impairment risk flagged
- High leverage (D/E 82.4th pct), thin coverage (1.4x), and cyclical housing/repair-remodel exposure
