Share count is a period average, so market cap is approximate.
Regeneron is a biotechnology company whose revenue long rested on a single eye medicine.
The base is a medicine for age-related macular degeneration, injected into the eye. It supplied most of the revenue for years and still does, but faces biosimilars and a competitor requiring less frequent injections. Defending that position means moving to a higher-dose formulation with longer intervals.
The second pillar is an immunology medicine developed with Sanofi for asthma, dermatitis and chronic obstructive pulmonary disease. It grows quickly and is gradually replacing ophthalmology as the main income source.
The company's distinguishing feature is its own antibody discovery platform, recognised in the industry and licensed to partners. The risks are the usual ones: trial results, regulatory decisions, price pressure. The company pays no dividend, directing cash into research and buybacks.
