What the company does
MKS Inc. makes instruments for chip fabs (vacuum, gas-flow, plasma control), lasers and chemicals for circuit boards (Atotech). Revenue is equipment sales to semiconductor and electronics makers.
What was checked
The AAOIFI standard has four steps: business activity first, then three financial ratios. Fail one and the stock is not halal.
Business activity
No prohibited activity
Interest-bearing debt / market cap

Interest-bearing debt $4.19B ÷ 36-month average market cap $10.51B = 39.8%

Pass
Non-compliant income / total revenue

Interest income $31.00M ÷ annual revenue $3.93B (2025) = 0.8%
0.8%
Pass
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: $16.90B.
For information (AAOIFI 3/1 note): cash + receivables are 16.1% 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.
