HUB Files draft prospectus F-4 to the SEC for the upcoming $1.28 billion SPAC Merger and listing of the company's shares for trading on Nasdaq

TEL AVIV, Israel, Aug 24, 2022 /PRNewswire/ -- HUB Cyber Security (Israel) Limited (TASE: HUB), a developer of Confidential Computing cybersecurity solutions and services ("HUB" or the "Company"), announced today that it has officially filed a non-confidential draft registration statement on Form F-4 which contains a preliminary proxy statement/prospectus to the U.S. Securities and Exchange Commission (SEC), for the purpose of completing the merger with the SPAC, the offering of the company's securities to the shareholders of the SPAC and the start of trading in the company's securities on Nasdaq.

The completion of the merger and the start of trading is subject to a number of conditions precedent. Subject to Israeli court approval, the company's shares are expected to be traded on the Nasdaq (only) without parallel trading in Tel-Aviv. The meaning for the company's current shareholders is that every holder of the company's shares that are currently traded on the Tel Aviv Stock Exchange in Israel, will hold after the completion of the merger identical shares of the Company that will be traded on the Nasdaq stock exchange.

Upon completion of the transaction, the projected gross proceeds received by the Company, before transaction costs will be a minimum amount of $50 million, if the SPAC owners make a full redemption of their investment; and up to a potential of approximately $225 million, if none of the SPAC shareholders redeem their investment

A copy of the preliminary draft proxy statement/prospectus is available for review on the SEC's website at www.sec.gov.
