Company Overview
About Merck & Co.
Merck & Co. is one of the world's largest research-driven pharmaceutical companies, founded in the United States in 1891 as a subsidiary of the German Merck KGaA and now an independent American company headquartered in Rahway, New Jersey, trading on NYSE (MRK). The company generated approximately $63.6 billion in revenues for FY2024 under CEO Robert Davis, anchored by Keytruda (pembrolizumab)—the world's best-selling cancer drug—which generated approximately $25 billion in global sales as the dominant checkpoint inhibitor immunotherapy across over 40 approved tumor indications including lung cancer, melanoma, bladder cancer, cervical cancer, and dozens more. Merck's animal health subsidiary, Merck Animal Health, is a global leader in livestock and companion animal medicines including Bravecto (flea/tick prevention) and contributes approximately $6 billion in revenues.
Business Model & Competitive Advantage
Keytruda's dominance in oncology immunotherapy is the defining financial fact of modern Merck: its combination use with chemotherapy as the standard first-line treatment for many cancers creates treatment pathways that benefit Merck when any of 40+ FDA-approved indications is diagnosed. The Bristol-Myers Squibb PD-1/PD-L1 checkpoint inhibitor (Opdivo) competes directly across many of the same tumor types, while AstraZeneca's Imfinzi, Pfizer/Merck's partnership on Bavencio, and Roche's Tecentriq represent alternative checkpoint blockade options. Merck's Gardasil HPV vaccine franchise—historically a $7-8 billion annual revenue contributor—experienced a sudden revenue collapse in China in 2024 as the Chinese government shifted policy away from recommending foreign HPV vaccines, eliminating approximately $2 billion in annual China revenue.
Competitive Landscape 2025–2026
In 2025-2026, Merck's most critical strategic challenge is the Keytruda patent expiration approaching in 2028-2030, which threatens $25+ billion in annual revenues. Merck's pipeline response includes subcutaneous Keytruda formulations (extending patent protection for formulation), Winrevair (sotatercept) for pulmonary arterial hypertension approved in 2024 targeting $4+ billion in peak sales, islatravir for HIV (partnership with Gilead), and multiple oncology combinations. The 2024 acquisition of Prometheus Biosciences for $10.8 billion adds TL1A inhibitor pipeline for inflammatory bowel disease. Merck's $15+ billion annual R&D budget and business development activities are entirely focused on filling the post-Keytruda revenue gap through 2030.
