SMX (Security Matters) Public Limited Company shares traded at $8.77, down 9.02%, after falling sharply from around $9.60 and finding support near $8.00 before a modest afternoon recovery. The move came as the company highlighted molecular marking technology designed to give physical materials unique identities linked to secure digital records. Its Digital Material Passport Platform records information across manufacturing, reuse, recycling, and resale, including material origin, recycled content, authenticity, movement, and ownership. SMX says the system can strengthen supply chain transparency, support recycling efficiency, improve resource management, and help manufacturers verify production and compliance claims. The technology is aimed at reducing reliance on documents, supplier information, and traditional labeling alone as companies face greater demands for manufacturing visibility and material verification. Stock performance remains influenced by market activity and company developments as SMX expands technology adoption.
