Description of Business	Description of Business Amicus Therapeutics, Inc. (the "Company") is a global, patient-dedicated biotechnology company focused on discovering, developing, and delivering novel medicines for rare diseases. The Company seeks to deliver the highest quality therapies that have the potential to obsolete current treatments, provide significant benefits to patients, and be first- or best-in-class. The Company's two marketed therapies are Galafold®, the first oral monotherapy for people living with Fabry disease who have amenable genetic variants, and Pombiliti® + Opfolda®, a novel two-component treatment for adults living with late-onset Pompe disease. Galafold® (also referred to as "migalastat"), is approved in over 40 countries around the world, including the United States ("U.S."), European Union ("E.U."), United Kingdom ("U.K."), and Japan. Additionally, Galafold® has been granted orphan drug designation in the U.S., E.U., U.K., Japan and several other countries. Pombiliti® + Opfolda® (also referred to as "cipaglucosidase alfa-atga/miglustat"), is approved in the U.S., the E.U., the U.K., Canada, Australia, Switzerland, and Japan. Multiple regulatory submissions and reimbursement processes with global health authorities are currently underway. Additionally, Pombiliti® + Opfolda® has been granted orphan drug designation or status in the U.S., U.K., Switzerland, and Japan and data exclusivity in the E.U. On April 30, 2025, the Company entered into an exclusive license agreement with Dimerix Bioscience Pty Limited ("Dimerix") for the commercialization of Dimerix' Phase 3 drug candidate, DMX-200, in the United States for treatment of Focal Segmental Glomerulosclerosis ("FSGS") and other indications. Refer to "— Note 6. Licensing Agreement," in our Notes to Consolidated Financial Statements. The Company had an accumulated deficit of $2.8 billion as of June 30, 2025 and anticipates incurring losses through the fiscal year ending December 31, 2025. The Company has historically funded its operations through stock offerings, product revenues, debt issuances, collaborations, and other financing arrangements. Based on its current operating model, which includes expected revenues, the Company believes the current cash position is sufficient to fund the Company's operations and ongoing research programs for at least the next 12 months. Potential business development opportunities, pipeline expansion, and investment in manufacturing capabilities could impact the Company's long-term capital requirements.
