A biotech with forward earnings priced at 8.6x, a PEG below 0.7, and free cash flow converting at 171% of net income is a quality business at an undemanding multiple — yet three consecutive earnings misses and a death cross technical hard block are actively working against that thesis, leaving the risk/reward favorable in theory at 6.5-to-1 but blocked in practice.

About BioMarin Pharmaceutical Inc.
About BioMarin Pharmaceutical Inc.
BioMarin Pharmaceutical's eight commercial therapies generated $3.2 billion in total revenues in 2025, with VOXZOGO (vosoritide for achondroplasia) at $926.9 million and VIMIZIM (elosulfase alpha for MPS IVA) at $792.1 million as the two largest contributors. ALDURAZYME for MPS I is commercialized exclusively by Sanofi globally, while all other products are marketed directly in the U.S., Europe, South America, and other significant markets. In December 2025, BioMarin signed a definitive agreement to acquire Amicus Therapeutics for approximately $4.8 billion in an all-cash transaction expected to close in the second quarter of 2026.
Revenue comes from rare-disease therapies sold through specialty pharmacies, hospitals, non-U.S. government agencies, and distributors. During 2025, three customers generated 37% of net product revenue, and Sanofi is the sole global customer for ALDURAZYME, purchasing all supply from BioMarin in exchange for royalties of 39.5% to 50% of worldwide net sales depending on volume. API for VOXZOGO, NAGLAZYME, PALYNZIQ, and ALDURAZYME is manufactured in-house at Novato, California; API for BRINEURA and VIMIZIM comes from Shanbally, Cork, Ireland, a facility that received EU drug product filling approval in 2024. PALYNZIQ and KUVAN API are sourced from third-party contract manufacturers. Generic versions of KUVAN have entered the U.S. and EU markets, continuing to erode KUVAN revenues. BioMarin's pipeline includes a pivotal Phase 3 VOXZOGO study in hypochondroplasia and Phase 1/2 data for BMN 351 in Duchenne Muscular Dystrophy showing 5.0% mean absolute dystrophin expression at week 25 in the 9 mg/kg cohort.
Show full overview
BioMarin's manufacturing relies on both in-house facilities and third-party contract manufacturers, and in certain instances there is only one approved contract manufacturer for specific aspects of the process. Similarly, certain raw materials are available from only a sole-source supplier—designated as the only recognized supply source with no alternative. A disruption at any sole-source supplier or single-approved contract manufacturer could delay product availability for ultra-rare diseases where patients have no therapeutic substitute and where regulatory re-qualification of backup suppliers is a lengthy, inspection-dependent process. The company mitigates this through safety stock and supply agreements but acknowledges future supply continuity cannot be guaranteed.
