Accounting Policies [Abstract]
BUSINESS OVERVIEW AND SIGNIFICANT ACCOUNTING POLICIES	BUSINESS OVERVIEW AND SIGNIFICANT ACCOUNTING POLICIES Nature of Operations BioMarin Pharmaceutical Inc. (the Company or BioMarin) is a leading, global rare disease biotechnology company focused on delivering medicines for people living with genetically defined conditions. Founded in 1997, the San Rafael, California-based company has a proven track record of innovation, with nine commercial therapies and a strong clinical and preclinical pipeline. Using a distinctive approach to drug discovery and development, BioMarin seeks to unleash the full potential of genetic science by pursuing category-defining medicines that have a profound impact on patients. Basis of Presentation These Condensed Consolidated Financial Statements have been prepared pursuant to U.S. generally accepted accounting principles (U.S. GAAP) and the rules and regulations of the SEC for Quarterly Reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. GAAP for complete financial statements, although management believes that the disclosures herein are adequate to ensure that the information presented is not misleading. The Condensed Consolidated Financial Statements should therefore be read in conjunction with the Consolidated Financial Statements and Notes thereto for the fiscal year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K. The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions have been eliminated. The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2026 or any other period. On April 27, 2026, the Company completed the acquisition of Amicus Therapeutics, Inc. (Amicus). The results of Amicus’ operations, along with the preliminary estimated fair values of assets acquired and liabilities assumed in the acquisition, have been included in the Condensed Consolidated Financial Statements since the closing of the acquisition on April 27, 2026. Refer to Note 2 – Acquisitions for additional details related to the Amicus acquisition. Management performed an evaluation of the Company’s activities through the date of filing of this Quarterly Report on Form 10-Q and has concluded that there were no subsequent events or transactions that occurred subsequent to the balance sheet date and prior to filing this Quarterly Report on Form 10-Q that would require recognition or disclosure in the Condensed Consolidated Financial Statements. Use of Estimates U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the Condensed Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from those estimates. The Condensed Consolidated Financial Statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair presentation of results for these interim periods. Significant Accounting Policies There were no changes to the Company’s significant accounting policies during the six months ended June 30, 2026, other than the update to the foreign currency policy following the acquisition of Amicus, as described below. The Company’s significant accounting policies are disclosed in Note 1 – Business Overview and Significant Accounting Policies to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Foreign Currency While the functional currency of the Company and certain subsidiaries continues to be the U.S. Dollar (USD), the functional currency of certain acquired foreign subsidiaries is their respective local currency. For subsidiaries whose functional currency is the USD, monetary assets and liabilities denominated in foreign currencies are remeasured using period-end exchange rates and non-monetary assets and liabilities are remeasured using historical exchange rates. Foreign currency transaction gains and losses resulting from the remeasurement are recognized in Other Income (Expense), Net in the Consolidated Statements of Income. For subsidiaries whose functional currency is their local currency, assets and liabilities are translated into USD using exchange rates in effect at the balance sheet date and income and expense items are translated using average foreign exchange rates for the period. Adjustments resulting from the translation of the financial statements of these certain foreign subsidiaries into USD are recorded in Accumulated Other Comprehensive Income (Loss), a separate component of stockholders' equity. Foreign currency transaction gains and losses arising from transactions denominated in a currency other than the subsidiary’s functional currency are recognized in Other Income (Expense), Net in the Consolidated Statements of Income. Recent Accounting Pronouncements There have been no new accounting pronouncements adopted by the Company or new accounting pronouncements issued by the Financial Accounting Standards Board (FASB) during the six months ended June 30, 2026, as compared to the recent accounting pronouncements described in Note 1 to the Company’s Consolidated Financial Statements of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, that the Company believes are of significance or potential significance to the Company.
