Business Description

Overview BioMarin Pharmaceutical Inc. (BioMarin, we, us or our) is a leading, global rare disease biotechnology company focused on delivering medicines for people living with genetically defined conditions. Our San Rafael, California-based company, founded in 1997, has a proven track record of innovation, with eight commercial therapies and a strong clinical and preclinical pipeline. Using a distinctive approach to drug discovery and development, we seek to unleash the full potential of genetic science by pursuing category-defining medicines that have a profound impact on patients. Recent Developments In 2025, we achieved $3.2 billion in total revenues, including a significant contribution from our ongoing expansion of VOXZOGO, and we continued to grow our commercial business and advance our product candidate pipeline. We believe that the combination of our internal research programs, partnerships and acquisitions of external assets will allow us to continue to develop and commercialize innovative therapies for patients with serious and life-threatening rare diseases and medical conditions. We periodically conduct strategic portfolio assessments of research and development programs to determine which we believe have the strongest combination of scientific merit, opportunity for commercial success and potential value creation for stockholders. Based on such strategic portfolio assessments, certain programs that do not meet our threshold for further development and commercialization could be discontinued. In December 2025, we entered into a definitive agreement to acquire Amicus Therapeutics, Inc. (Amicus), a publicly traded, global, biotechnology company for $14.50 per share in an all-cash transaction for a total consideration of approximately $4.8 billion. The pending acquisition is expected to strengthen our commercial portfolio by adding two new therapies for the treatment of Fabry disease and late-onset Pompe disease. The transaction is expected to close in the second quarter of 2026, subject to regulatory clearances, approval by the stockholders of Amicus and other customary closing conditions. We intend to finance the transaction through a combination of cash on hand and approximately $3.7 billion of non-convertible debt financing. In December 2025, we entered into a debt financing commitment letter and related fee letter with certain lenders, pursuant to which the lenders have committed to provide us with debt financing up to approximately $3.7 billion (the Bridge Commitment) in the form of a 364-day senior secured bridge loan facility (Bridge Facility) for the pending acquisition of Amicus. No amounts had been drawn or were outstanding under the Bridge Commitment as of December 31, 2025. In February 2026, we issued $850.0 million in aggregate principal amount of 5.5% senior unsecured notes due 2034 (the 2034 Notes), and the proceeds from the issuance were deposited into an escrow account that will be used to finance the pending acquisition of Amicus. In connection with the issuance of the 2034 Notes, the Bridge Commitment was reduced from approximately $3.7 billion to $2.8 billion. In place of the Bridge Facility, we also expect to enter into a senior secured term loan facility for approximately $2.8 billion in aggregate principal and a new $600.0 million senior secured revolving credit facility in 2026 that will be executed prior to or concurrently with the closing of the pending Amicus acquisition. See Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations–Financial Condition, Liquidity and Capital Resources" below for additional information. In October 2025, we announced our plan to pursue options to divest ROCTAVIAN, including exploring out-licensing opportunities. Subsequently in December 2025, we committed to a plan to voluntarily withdraw ROCTAVIAN from the market due to lower than previously anticipated commercial opportunities. In connection with this strategic decision, we recorded approximately $240.0 million of restructuring charges in 2025 comprised of an inventory write-off, impairment of long-lived assets, severance and other costs. See Note 19 to our accompanying Consolidated Financial Statements for additional details. In July 2025, we completed the acquisition of Inozyme Pharma, Inc. (Inozyme), a publicly traded clinical-stage biopharmaceutical company dedicated to developing innovative therapeutics.…
