Explanation of responses
- F1On September 19, 2024, the Issuer announced the implementation of a reverse stock split whereby every 25 outstanding ARQQ ordinary shares were consolidated into one ordinary share, par value $0.0025 per share. Each Business Combination Warrant has an exercise price of $11.50 and can be exercised at any time, at the holder's election, to purchase 0.04 of an ARQQ ordinary share on a post-reverse stock split basis, and cannot be exercised for fractional shares. Accordingly, on a post-reverse stock split basis holders of Business Combination Warrants are required to exercise at least 25 Business Combination Warrants in order to receive one whole ARQQ ordinary share at an aggregate exercise price of $287.50 per whole ARQQ ordinary share. The reporting person beneficially owns 352,421 Business Combination Warrants, which, if exercised in full, would be equivalent to 14,096.84 ARQQ ordinary shares on a post-reverse stock split basis.
- F2The price reported is a weighted average price. The Business Combination Warrants were sold in multiple transactions at prices ranging from $1.14 to $1.32 per Business Combination Warrant, inclusive. The reporting person undertakes to provide to the Issuer, any security holder of the Issuer or the staff of the Securities and Exchange Commission (the "Commission"), upon request, full information regarding the number of Business Combination Warrants sold at each separate price within the range set forth in this footnote.
