under the ticker “SMX” and warrants to commence trading on the Nasdaq Capital

Market under the symbol “SMXWW” on March 8, 2023

New York, New York, March 8, 2023 – SMX (Security Matters) Public Limited Company (formerly Empatan Public Limited Company) today announced the closing of its previously announced business combination with Lionheart III Corp (NasdaqCM: LION, LIONW) (“Lionheart”). SMX’s ordinary shares are expected to commence trading on the Nasdaq Global Market, and warrants are expected to commence trading on the Nasdaq Capital Market, on March 8, 2023 under the ticker symbols “SMX” and “SMXWW.”

Prior to the commencement of trading of SMX’s ordinary shares and warrants on Nasdaq, the trading on the Australian Security Exchange of Security Matters Limited, SMX’s wholly-owned subsidiary as of the closing of the business combination with Lionheart, as well as the trading of the securities of Lionheart on Nasdaq, are expected to cease. Shareholders of Security Matters Limited who own shares of that company will receive securities in SMX in accordance with the terms of the business combination.

Haggai Alon, Chief Executive Officer of SMX, stated, “The closing of the business combination with Lionheart represents a wonderful step forward in the development and global recognition of SMX. We expect that the business combination of SMX with the Miami-based Lionheart, which was first announced in July 2022, will buoy SMX’s position as a leader in enabling supply chain authentication, traceability, and transparency, transforming businesses for participation in the circular economy.”

SMX’s technology originated in Israel and was originally developed by the Israeli Security Establishment and Nuclear Atomic Agency. It is a proven technology that the Company expects will be reliable, operational, and scaled up at a national level. After its predecessor enjoyed several years on the Australian Securities Exchange, SMX will now be listed on Nasdaq as a new segment creator for the circular economy and industrial technology.

“The listing on Nasdaq, which is the world’s premier exchange for technology companies and investors, is a tremendous achievement for SMX and, together with our partnership with the Lionheart team, provides SMX with immense opportunities to further access highly valued strategic partners, as well as institutional and other investors. We look forward to working together to expand our business, continue our execution of existing relationships and opportunities, access additional verticals and build our public market,” further commented Mr. Alon.

Ophir Sternberg, Chairman and Chief Executive Officer of Lionheart III said: “Global markets demand companies be better prepared for transparency, efficiency and resiliency, and
