What You Should Know

Merck & Co. (known as MSD outside the United States and Canada) is a US-headquartered global pharmaceutical company organized into two reporting segments: Pharmaceutical (prescription human-health medicines and vaccines including the lead oncology franchise built around Keytruda — pembrolizumab, an anti-PD-1 immune checkpoint inhibitor that is the largest-selling oncology drug globally — plus the vaccine franchise including Gardasil for HPV, Pneumovax and Vaxneuvance for pneumococcal disease, and ProQuad/M-M-R II for measles-mumps-rubella, the cardiovascular and diabetes franchises, the HIV franchise, the hospital and specialty care franchises, and various other primary-care medicines) and Animal Health (livestock and companion-animal pharmaceuticals, vaccines, parasiticides, and animal-identification products through Merck Animal Health, one of the global leaders in animal health). Pharmaceutical and vaccine development, manufacture, and distribution is unambiguously permissible at the activity level under standard Sharia methodology — Merck's medicines serve to preserve life and treat serious disease, a clearly permissible therapeutic mission. The financial screen passes comfortably: Merck operates an investment-grade balance sheet with conservative leverage and the debt-to-market-cap ratio sits well below the 33% Sharia threshold. Most major Sharia advisory boards classify Merck as permissible with purification of small interest-income components on cash and short-term investment balances.
