Lionheart III Corp (NASDAQ:LIONW) operates as a blank check company, or special purpose acquisition company (SPAC), focused on effecting mergers, capital stock exchanges, asset acquisitions, stock purchases, reorganizations, or similar business combinations with one or more businesses; it holds no significant operations or products of its own prior to completing an initial business combination. Incorporated in 2021 and headquartered in Miami, Florida, the company raised $230 million in its initial public offering in December 2020, with proceeds placed in trust, and units trading under LIONU with redeemable warrants under LIONW exercisable at $11.50 per share after a business combination. In March 2023, Lionheart III completed a de-SPAC merger with Security Matters Limited (SMX), an Australian brand protection technology firm specializing in supply chain authentication using unique markers and blockchain technology; track and trace solutions for recycling and manufacturing; and related transparency services for manufacturers, brands, and consumers; post-merger, Lionheart survives as a wholly-owned subsidiary of SMX Public Limited Company (NASDAQ:SMX), with LION shares, units, and warrants suspended from trading while LIONW warrants remain listed but at minimal value, reflecting the transaction's completion and SMX's Nasdaq listing under new symbols.
