BioMarin Pharmaceutical Inc. experienced a significant price increase of 13.00%, reaching a 20-day high amid positive market conditions, with the Nasdaq-100 up 0.81% and the S&P 500 up 0.22%.
This surge is attributed to BioMarin's announcement of a $4.8 billion acquisition of Amicus Therapeutics, which is expected to enhance its portfolio in rare disease treatments. The deal, valued at $14.50 per share, is anticipated to accelerate revenue growth and significantly impact BioMarin's earnings per share within the first year after closing, with substantial benefits expected starting in 2027.
The acquisition not only strengthens BioMarin's market position but also adds two high-growth therapies, Galafold and Pombiliti + Opfolda, which are projected to drive long-term revenue growth through 2030 and beyond.
