The Pre-Funded Warrants are exercisable at any time after their original issuance and on or prior to the five-year anniversary of the original issuance date. A holder of Pre-Funded Warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 19.99% of the number of the Company’s ordinary shares outstanding or more than 19.99% of the combined voting power of the Company’s securities outstanding immediately after giving effect to such exercise, unless and until shareholder approval is obtained.•On December 7, 2023, the Company entered into an underwriting agreement relating to the issuance and sale in an underwritten offering of the Company’s ordinary shares.
