The foregoing discussion and table are based on 37,427,265 ordinary shares outstanding as of December 31, 2024, and exclude, as of that date, the following number of shares outstanding: • 2,258,319 ordinary shares issuable upon exercise of warrants outstanding as of December 31, 2024 at a weighted average exercise price of €7.82 per ordinary share; and • 346,431 ordinary shares issuable upon exercise of warrants that are outstanding as of December 31, 2024 but not yet granted. To the extent that outstanding warrants are exercised, you will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities may result in further dilution to our shareholders.
