MTM Managing Director & CEO, Michael Walshe, commented: “Graduating to OTCQX is a key milestone in our U.S.-focused strategy, providing increased visibility and access for North American investors. It enables trading and settlement in U.S. dollars during local market hours, removing friction for our growing U.S. investor base. With development of our first U.S.-based Flash Joule Heating facility underway in Texas and strategic partnerships continuing to gain traction, the timing of this upgrade couldn’t be better. “Moreover, as part of our broader U.S. capital markets strategy, we are also reviewing the potential introduction of a Level I ADR program to further enhance access for U.S. investors. This complements our efforts to position Metallium as a leading U.S.-based industrial technology company at the forefront of critical metal recovery and supply chain resilience”. “The Company continues to actively advance strategic partnerships across the U.S. and globally. Following last week’s heavily oversubscribed, institutional-only $50 million capital raise, which lifted institutional ownership to nearly 35%, this OTCQX uplisting is expected to further support those ongoing discussions and the Company’s broader ambition to deepen U.S. institutional participation on the register”. ENGAGE WITH THIS ANNOUNCEMENT ON INVESTORHUB: HERE ASX: MTM | OTCQX: MTMCF ABOUT OTC MARKETS OTCQX is the highest tier of OTC Markets Group, designed for established, investor-focused U.S. and international companies. To qualify, companies must meet stringent financial, governance and compliance standards. Metallium’s uplisting supports its transition into an industrial technology business focused on commercialising proprietary Flash Joule Heating technology to recover high-value strategic and precious metals from critical mineral concentrates and high-grade waste streams. FURTHER ENHANCEMENTS FOR U.S. INVESTOR ACCESS UNDER REVIEW The Company is also evaluating the potential establishment of a sponsored Level I American Depositary Receipt (ADR) program. An ADR is a U.S.-traded security that represents shares in a foreign company, providing U.S. investors with a more convenient and familiar way to gain exposure to offshore equities. If implemented, an ADR program would enable Metallium shares to be traded in U.S. dollars and held through U.S. brokerage accounts, further improving accessibility and visibility in North America. Importantly, any such program would be nondilutive, would not involve the issuance of new shares, and would have no impact on existing ASX shareholders or the Company’s primary listing on the Australian Securities Exchange. This announcement has been authorised for release by the Board of Directors.
