 Hadron Restricted Shares that are issued and outstanding immediately prior to the Effective Time, and (c) all shares of Hadron Common Stock issuable upon full exercise of all Hadron Options outstanding as of immediately prior to the Effective Time (calculated using the treasury method of accounting on a cashless exercise basis). The GigCapital7 Units, GigCapital7 Class A Ordinary Shares and GigCapital7 Warrants are currently listed on the Nasdaq Stock Market LLC (“ Nasdaq”) under the symbols “GIGGU”, “GIG” and “GIGGW”, respectively. Pursuant to the terms of the Business Combination Agreement, as a closing condition (subject to certain exceptions), the Domesticated GigCapital7 Common Stock issued in connection with the Business Combination is to be conditionally approved for listing on Nasdaq, but there can be no assurance that such closing condition will be met. If such closing condition is not met, the Business Combination will not be consummated unless the listing condition is waived by the parties to the Business Combination Agreement. Following the Closing, it is proposed that Domesticated GigCapital7 will be renamed “Hadron Energy, Inc.” and the Domesticated GigCapital7 Common Stock and Domesticated GigCapital7 Warrants will be listed, subject to Nasdaq approval, under the proposed symbols “HDRN” and “HDRNW”, respectively. It is important for you to know that, at the time of the GigCapital7 extraordinary general meeting, we may not have received from Nasdaq either confirmation of the listing of the Domesticated GigCapital7 Common Stock and Domesticated GigCapital7 Warrants or that approval will be obtained prior to the consummation of the Business Combination, and it is possible that the listing condition to the consummation of the Business Combination may be waived by the parties to the Business Combination Agreement. As a result, you may be asked to vote to approve the Business Combination and the other proposals included in this proxy statement/prospectus without such confirmation, and, further, it is possible that such confirmation may never be received and the Business Combination could still be

consummated if such listing condition is waived or is subject to an exception and therefore the Domesticated GigCapital7 securities would not be listed on any nationally recognized securities exchange. In connection with GigCapital7’s IPO (as defined in the accompanying proxy statement/prospectus), GigAcquisitions7 Corp., a Cayman Islands exempted company (the “ Sponsor”), and GigCapital7’s directors and executive officers entered into a letter agreement,
