Is WST (West Pharmaceutical Services, Inc.) Halal or Haram?

Based on our AAOIFI-standard shariah screening, WST is Halal and considered permissible for Muslim investors. It passed all 4 of 4 compliance screens including business activity review, debt-to-market-cap ratio (2.02% vs ≤33% threshold), interest income ratio (0.58% vs ≤5% threshold), and cash & securities ratio (3.83% vs ≤33% threshold).

West Pharmaceutical Services, Inc. (WST) is a key player in the healthcare sector, specializing in the design and manufacture of containment and delivery systems for injectable drugs. Operating globally, the company produces essential medical supplies such as stoppers, seals, and advanced syringe components that ensure the safe administration of healthcare products. For Muslim investors, WST represents a strong Halal investment opportunity as it successfully passes all four AAOIFI Shariah screens. The company's core operations in medical instruments are fully permissible, and its financial structure strictly adheres to Islamic guidelines, meaning investors can confidently add this stock to their halal portfolios. From a financial perspective, WST boasts an incredibly clean balance sheet that aligns perfectly with Islamic finance principles. The company's Debt to Market Cap ratio sits at a mere 2.0%, while interest-generating cash and securities account for only 3.8% of its market cap, both remaining far below the strict 33% AAOIFI thresholds. Because West Pharmaceutical Services operates in a universally permissible industry with virtually no reliance on interest-bearing debt, there is no significant scholarly debate regarding its compliance. Halal investors should simply continue to monitor its quarterly earnings to ensure debt and interest income ratios remain comfortably within permissible limits. West Pharmaceutical Services, Inc. operates in the Healthcare sector under the Medical - Instruments & Supplies industry and is headquartered in Exton, PA, US. The company is led by CEO Eric Green and employs approximately 10,600 people.

WST was screened using AAOIFI-based shariah compliance criteria. Four tests are applied: (1) Business Activity — the company's core business must not derive primary income from haram (prohibited) activities such as alcohol, gambling, tobacco, or interest-based finance. (2) Debt-to-Market-Cap — total debt must not exceed 33% of market capitalization. (3) Interest Income — interest income must not exceed 5% of total revenue. (4) Cash & Securities — cash and interest-bearing securities must not exceed 33% of market cap. WST passed 4 of these 4 screens.

Although WST passes all shariah screens, it does earn $17.7M in interest income (0.58% of revenue). Many scholars recommend purifying this portion by donating the equivalent percentage of any dividends received to charity. For example, if you receive $100 in dividends, you would donate approximately $0.58 to purify the income.

WST was last screened on 2026-04-29. Shariah compliance status can change as companies report new financial data, acquire new businesses, or shift revenue streams. We recommend checking back periodically for the most up-to-date screening results.
