What each company does and how it makes money
Regeneron Pharmaceuticals is a biotechnology company that discovers, develops, and commercializes innovative medicines for serious diseases. It generates revenue primarily from sales of its flagship products — EYLEA for eye diseases (~60% of revenue) and Dupixent for inflammatory conditions (~30%) — with additional income from collaborations and royalties. The company's competitive advantage lies in its proprietary VelocImmune technology platform for creating human antibodies and its deep expertise in genetic research, which enables rapid drug discovery and development.

It generates revenue primarily from product sales of approved drugs — like its dermatology and immunology treatments — supplemented by licensing deals and research collaborations with larger pharmaceutical partners. Its key advantage is its decentralized "Vant" model, which allows for focused development of individual drug candidates while sharing centralized resources and expertise across the portfolio.
