1.2Basis of Preparation

These Consolidated Financial Statements were authorized for issue by the Board of Directors of the Company (the “Board”) on April 8, 2026, and are subject to approval at the annual meeting of shareholders to be held on April 9, 2026.

The Group’s Consolidated Financial Statements are prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (“IASB”) and the requirements of the Swiss Code of Obligations. The Consolidated Financial Statements are expressed in Euros (''EUR'') (presentation currency) and prepared on a historical cost basis, except for certain financial assets and liabilities which are measured at fair value.

In 2025, the Group elected to present three years of consolidated financial information, comprising the current year and two comparative periods, to enhance comparability following the change in presentation currency. The Group has chosen to apply IAS 33 Earnings per Share (Note 1.4).

The principal accounting policies adopted in the preparation of these Consolidated Financial Statements are set out in the specific notes to the financial statements. These policies have been consistently applied for all years presented, unless otherwise stated.

Management has assessed the Group’s ability to continue as a going concern and, despite the negative equity position and current loss situation, concluded that it has sufficient resources to continue its operations for at least twelve months from the date of authorization of these Consolidated Financial Statements. This conclusion is supported by the successful completion of a comprehensive refinancing, which provides the Group with adequate liquidity and financial flexibility to continue its operations and meet its obligations as they fall due over this period.
