| Auditor Opinion [Text Block] | Opinion on the Financial Statements We have audited the accompanying consolidated statements of financial position of Birkenstock Holding plc (the Company) as of September 30, 2025 and 2024, the related consolidated statements of comprehensive income, changes in shareholders’ equity and cash flows for each of the three years in the period ended September 30, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at September 30, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2025, in conformity with IFRS Accounting Standards as issued by the International Accounting Standards Board. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated December 18, 2025 expressed an adverse opinion thereon. |
