BioMarin Pharmaceutical Inc

BioMarin Pharmaceutical Inc. is a San Rafael, California-based biotechnology company founded in 1997 that focuses on medicines for genetically defined rare diseases. Its business is built around eight commercial therapies, including VOXZOGO, VIMIZIM, NAGLAZYME, PALYNZIQ, ALDURAZYME, BRINEURA, KUVAN and ROCTAVIAN, plus a pipeline of clinical and preclinical programs. The company develops and commercializes category-defining treatments for serious and life-threatening conditions where patient populations are small but medically urgent. BioMarin sells directly in the U.S. and major international markets, while also using distributors and partners in selected countries. Its model combines internal R&D, targeted acquisitions and partnerships to expand its rare-disease portfolio over time.

    Purchase infused or administered therapies for rare-disease patients, especially in the U.S. and Europe.

  • Government purchasers and public health systemsprimary

    Place periodic large orders in certain countries, which drives international volume but also creates timing volatility.

  • Authorized distributorssecondary

    Buy products for selected non-U.S. markets and handle local regulatory and commercial execution.

Dependence on a limited number of commercial products

A large share of revenue comes from a small set of rare-disease therapies, so any slowdown in one product can materially affect results.

Generic competition and loss of exclusivity

KUVAN has already been pressured by generic competition, showing the vulnerability of mature products after exclusivity ends.
