Is REGN (Regeneron Pharmaceuticals, Inc.) Halal or Haram?

Based on our AAOIFI-standard shariah screening, REGN 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 (3.56% vs ≤33% threshold), interest income ratio (5.00% vs ≤5% threshold), and cash & securities ratio (11.32% vs ≤33% threshold).

Regeneron Pharmaceuticals, Inc. is a leading biotechnology company that discovers and commercializes medicines for serious medical conditions. Its flagship products include EYLEA, an injection used to treat retinal diseases like macular degeneration, and Dupixent, a widely used treatment for atopic dermatitis and asthma. For Muslim investors, Regeneron represents a Halal investment opportunity within the healthcare sector, having successfully passed all four AAOIFI screening criteria. The company's core business of developing therapeutic medicines is fundamentally permissible, aligning well with Islamic principles of preserving life and health. From an Islamic finance perspective, Regeneron boasts an incredibly strong balance sheet with a debt-to-market cap ratio of just 3.6%, well below the 33% threshold. Its cash and interest-bearing securities also pass comfortably at 11.3% of its market capitalization, indicating minimal reliance on conventional, interest-based leverage. While the stock is currently compliant, halal investors must pay strict attention to Regeneron's interest income, which currently sits exactly at the 5.00% AAOIFI maximum limit. Any slight increase in interest-generating cash equivalents could push the stock into non-compliant territory in upcoming earnings reports, making routine dividend purification and quarterly monitoring essential. Regeneron Pharmaceuticals, Inc. operates in the Healthcare sector under the Biotechnology industry and is headquartered in Tarrytown, NY, US. The company is led by CEO Leonard S. Schleifer and employs approximately 15,158 people.

REGN 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. REGN passed 4 of these 4 screens.

Although REGN passes all shariah screens, it does earn $716.8M in interest income (5.00% 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 $5.00 to purify the income.

REGN 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.
