What the company does
Builders FirstSource is the largest US supplier of building materials to homebuilders: lumber, prefabricated trusses and wall panels, doors and windows. Revenue comes from material sales to builders.
What was checked

No data
Figures from the company's filings (2026-06-30), USD. Market cap is a 36-month average (the S&P Shariah index approach), so a one-day price move does not flip the verdict. Today's market cap: $5.88B.
For information (AAOIFI 3/1 note): cash + receivables are 16.3% of total assets (2026-06-30). AAOIFI recommends tangible assets of at least one third — this figure does not affect the verdict, and other major screeners do not apply it either.
