What the company does
Waters makes lab instruments: liquid chromatography and mass spectrometry (drug quality testing) and thermal analysis (TA Instruments). Customers are pharma and labs; its money comes from instruments, consumables and services.
What was checked
The AAOIFI standard has four steps: business activity first, then three financial ratios. Fail one and the stock is not halal.

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: $42.91B.
For information (AAOIFI 3/1 note): cash + receivables are 10.2% 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.
