Investment Highlights Why It Matters Which of these 2 stories sounds closer for this stock?

1. Generates cash flow

The stock generated 4% or more of the share price (called cash flow yield), and shows moderate 10-15% or more growth.

2. Riding a trend

Think Tesla during the pandemic of 2020 when EVs were riding a cultural high, or Nvidia in the current AI boom, or even Figma. These companies don’t have enough yield, or, enough growth, or both - however - they are riding a trend. They have momentum. These can be more volatile - they don’t have the floor of strong cash flow

Why The Stock Moved


Qualitative Assessment

AI Generated Analysis | Feedback

Here are the key points for why BioMarin Pharmaceutical (BMRN) stock moved, particularly around the 4.9% range, for the approximate time period from August 31, 2025, to today: **1. BioMarin's acquisition of Amicus Therapeutics for $4.8 billion. **On December 19, 2025, BioMarin announced its definitive agreement to acquire Amicus Therapeutics in an all-cash transaction valued at approximately $4.8 billion. This news caused BMRN stock to rise by 4.7% in premarket trading. The acquisition is expected to expand BioMarin's leadership in rare diseases, add two marketed treatments (Galafold for Fabry disease and Pombiliti + Opfolda for Pompe disease) to its portfolio, accelerate revenue growth, and be accretive to non-GAAP diluted earnings per share within the first 12 months after closing.

**2. Positive regulatory development for PALYNZIQ.** On October 29, 2025, the FDA accepted BioMarin's Supplemental Biologics License Application for PALYNZIQ® (pegvaliase-pqpz) for Priority Review. This application seeks to expand the use of PALYNZIQ to adolescents aged 12-17 with Phenylketonuria.

**3. Solid third-quarter 2025 revenue growth and updated guidance.** On October 27, 2025, BioMarin reported its third-quarter 2025 financial results, showing total revenues of $776 million, an increase of 4% compared to the same period in 2024. This growth was primarily driven by strong revenue performance from VOXZOGO® and PALYNZIQ®. The company also increased its full-year 2025 total revenue guidance at the midpoint.
