CONTENTS

Warrant Term Extension

HUB Cyber Security Ltd. (the “Company”) has outstanding warrants to purchase 68,837 of its ordinary shares exercisable at 744.12 NIS (approximately $216.75 per ordinary share), all of which were issued in connection with a private financing in February 2022 (the “2022 Warrants”). These warrants currently trade on the Nasdaq Capital Market under the symbol “HUBCZ.” The 2022 Warrants were scheduled to expire on August 22, 2025. To allow additional time for the 2022 Warrants to be exercised and to potentially generate future cash proceeds to the Company, on August 11, 2025, the Board of Directors of Company decided to extend the expiration date of the 2022 Warrants to 5 p.m. Eastern Time on August 22, 2027. No action is required by the holders of the 2022 Warrants to effectuate this modification and all provisions of the 2022 Warrants (as adjusted by any reverse share splits undertaken by the Company or other adjustment events contained therein) remain in full force and effect. None of the 2022 Warrants are held by officers, directors or affiliates of the Company.

The information in this Report on Form 6-K, including in Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing made by the Company under the Securities Act of 1933, as amended, or the Exchange Act, except as otherwise set forth herein or as shall be expressly set forth by specific reference in such a filing.
