What the company does
Mueller Industries makes copper tube and fittings (plumbing, HVAC), aluminium/brass products and climate-system components. Its money comes from metal-product sales.
What was checked

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: $13.49B.
For information (AAOIFI 3/1 note): cash + receivables are 51.2% 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.
