Novo Nordisk 

With roughly one-third of the global branded diabetes treatment market, Novo Nordisk is the world's leading provider of diabetes care products. Based in Denmark, the company manufactures and markets a variety of human and modern insulins for patients with diabetes, as well as injectable and oral GLP-1 therapies, across its obesity and diabetes care segment. Novo also has a rare disease segment (contributing less than 10% of revenue) that specializes in protein therapies for hemophilia and other disorders.
