  1. On 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 366,463 Business Combination Warrants, which, if exercised in full, would be equivalent to 14,658.52 ARQQ ordinary shares on a post-reverse stock split basis. The price reported is a weighted average price. The Business Combination Warrants were sold in multiple transactions at prices ranging from $1.35 to $1.40 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. The price reported is a weighted average price. The Business Combination Warrants were sold in multiple transactions at prices ranging from $1.07 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 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.

Business Combination Warrants financial
"The reporting person beneficially owns 366,463 Business Combination Warrants, which, if exercised in full..."
reverse stock split financial
"the Issuer announced the implementation of a reverse stock split whereby every 25 outstanding ARQQ ordinary shares..."
A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.
weighted average price financial
"The price reported is a weighted average price. The Business Combination Warrants were sold in multiple transactions..."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
beneficially owns financial
"The reporting person beneficially owns 366,463 Business Combination Warrants, which, if exercised in full..."
Beneficially owns means a person or entity enjoys the economic benefits and control of a security even if the legal title or registration is held in another name. Think of it like having the keys and profits from a car that is registered to a friend: you use it, benefit from it, and make decisions about it even though the official paperwork lists someone else. For investors, this matters because it reveals who truly controls shares, affects voting power, potential conflicts of interest, and regulatory disclosure obligations.
Securities and Exchange Commission regulatory
"the staff of the Securities and Exchange Commission (the "Commission"), upon request, full information..."
A national government agency that enforces rules for buying, selling and disclosing information about stocks and other investments, acting like a referee and scorekeeper for financial markets. It requires companies to share clear, regular financial and business information and investigates fraud or rule-breaking, which matters to investors because those rules and disclosures help ensure fair prices, reduce hidden risks and make it easier to compare investment choices.
