SMX (Security Matters PLC (the “Company”) is filing this Report on Form 6-K to provide an update on its previously announced Heads of Agreement, dated December 5, 2024 (the “Heads of Agreement”) with Ybyrá Capital S.A. (“Ybyrá”), an emerging holding company focused in commodities and real estate development in South America. The Company and Ybyrá continue to structure the terms of the combination, aiming to maximize value for each of their shareholders.

At this stage, both companies are in the initial phase of determining the necessary structure and documentation to ensure that the transaction is conducted in compliance with applicable laws in the United States and Brazil, and Nasdaq listing requirements.

It also involves a detailed analysis of an independent third party to define the quality and updated value of Ybyrá’s assets, as well as a specialized technical team at SMX to prepare the unique certifying process for those assets.

Additionally, both companies are continuing to negotiate key deal terms.

While SMX remains at this time committed to the potential transaction and believes Ybyrá is similarly committed, the non-binding Heads of Agreement provides a roadmap, including the need for further due diligence, regulatory and shareholder approvals, and the parties have not yet finalized the principle deal terms or commenced drafting of definitive transaction documents. The parties cannot at this time give any assurance that definitive documents will be executed or delivered, that both companies will satisfy all expected closing conditions, including stockholder approvals, or that the transaction will be consummated in the first half of 2025 as originally targeted, later in 2025 or ever.
