Who makes it
5 companies produce recombinant insulin api (bulk drug substance).
World's largest insulin manufacturer. Controls ~33.7% of global diabetes care market; ~45% of human insulin. Operates the world's largest insulin production facility in Kalundborg, Denmark (produces ~50% of global insulin supply). Dominant in GLP-1 drugs (Ozempic/Wegovy); FY2024 revenue DKK 232B. Uses both E. coli and yeast fermentation.
Second-largest insulin manufacturer; invented the first commercial insulin (1923). Uses Saccharomyces cerevisiae (yeast) fermentation exclusively. Markets Humalog (lispro), Basaglar (glargine), and Lyumjev. Also dominant in GLP-1 market (Mounjaro/Zepbound). FY2024 revenue ~$45B.
Third of the global insulin oligopoly. Markets Lantus (glargine) — historically the world's best-selling insulin — and Toujeo. Uses E. coli fermentation at Frankfurt plant. WHO-prequalified for insulin glargine. Divesting insulin business in some regions as GLP-1 market grows.
Intas Pharmaceuticals (Ahmedabad Gujarat India; privately held; founded 1976 by Hasmukh Chudgar; ~$2.4B revenue est. 2022) is the world's largest manufacturer of cisplatin and carboplatin APIs and one of India's largest private pharmaceutical companies. Intas operates its international generic injectable business under the brand Accord Healthcare (UK-registered subsidiary). Intas's Ahmedabad/Sanand API manufacturing complex in Gujarat was the single most important source of cisplatin API for the US market, supplying an estimated 50-60% of US cisplatin imports from its Gujarat facilities. In November 2022, FDA investigators conducting a pre-approval inspection at Intas's Ahmedabad manufacturing facility (FEI 3003889748) discovered hundreds of trash bags filled with shredded quality-control documents — evidence of deliberate document destruction intended to conceal data integrity violations. FDA issued a Form 483 with 10 observations. The FDA subsequently issued a Warning Letter in December 2022. Intas voluntarily ceased API production at the facility. The resulting API supply gap triggered the worst US oncology drug shortage in a decade, beginning in February 2023 for cisplatin and April 2023 for carboplatin. The Intas-Accord shortage became the central case study for pharmaceutical supply chain concentration risk.
Indian biotechnology and pharmaceutical company (NSE: BIOCON; Biocon Biologics listed separately; HQ Bangalore; ~₹150B revenue for Biocon group); Biocon is India's largest biopharmaceutical company and a major producer of complex small molecules and biologics including cyclosporine A API and immunosuppressants. Biocon Limited was founded in 1978 by Kiran Mazumdar-Shaw — one of India's most prominent female entrepreneurs — as an enzyme fermentation company, starting in a garage with ₹10,000 in capital. Today Biocon is a ~$3B revenue pharmaceutical company producing insulin biosimilars, cancer biologics, and complex small molecule APIs including cyclosporine A. The same Biocon that produces the cyclosporine A API for generic dry eye drops also produces trastuzumab biosimilar (Herceptin equivalent for breast cancer) and insulin analogs for diabetes — one Indian startup from 1978 spanning oncology, endocrinology, and ophthalmology API supply chains.
