Amicus Therapeutics Stock (FOLD) News: BioMarin’s $14.50 Cash Buyout, Deal Timeline, and the Latest Forecasts (Dec. 21, 2025)
As of Sunday, December 21, 2025, Amicus Therapeutics, Inc. (NASDAQ: FOLD) has effectively shifted from a “biotech story stock” to a deal-driven stock. The reason is simple and decisive: BioMarin Pharmaceutical (NASDAQ: BMRN) agreed to acquire Amicus in an all-cash transaction priced at $14.50 per share, putting a hard cap on the near-term upside—unless a competing bid emerges. SEC+1 With U.S. markets closed for the weekend, the most recent close available is $14.18 (Dec. 19, 2025)—a roughly 30% one-day jump that pushed shares close to the deal price and turned the remaining gap into a classic merger-arbitrage spread.
