GSTX begins trading on OTCQB after uplisting approval

Graphene & Solar Technologies Limited started trading on the OTCQB Venture Market on Sept. 15, 2026, a move the company says should widen investor reach as it pursues a U.S. silicon wafer manufacturing buildout. The upgrade comes alongside a planned $40 million convertible note offering and a San Diego production strategy tied to future Nasdaq ambitions.

Why it matters: - The OTCQB move gives GSTX a higher visibility trading venue and may make the stock easier for institutional and retail investors to access. - The uplisting also strengthens GSTX’s capital-markets profile as the company tries to finance and scale its U.S. silicon wafer manufacturing plan. - GSTX is positioning the move as a step toward a potential future Nasdaq listing.

What happened: - Graphene & Solar Technologies Limited, which trades under the ticker GSTX, was approved for the OTCQB Venture Market. - Trading on OTCQB began on Sept. 15, 2026, under the existing symbol GSTX. - OTC Markets Group approved the application after GSTX met OTCQB financial, reporting, verification and market-eligibility standards. - Those standards are higher than the OTCID Basic Market requirements.

The details: - GSTX is conducting a private offering of up to $40 million of convertible notes. - The company plans to use the net proceeds, if the offering closes, to support development of its U.S. silicon wafer manufacturing operations. - The convertible notes are not registered under the Securities Act of 1933 or state securities laws. - The notes cannot be offered or sold in the United States without registration or an available exemption. - The press release does not constitute an offer to sell or a solicitation to buy securities. - Through its U.S. subsidiary, Quartz & Silicon Materials Company Limited, or QSM USA, GSTX’s near-term focus is planned silicon wafer production in San Diego, California. - When fully operational, the existing industrial facility is expected to provide up to 10 GW of wafer capacity a year. - QSM USA has a long-term offtake agreement with a U.S. solar manufacturer for 30% of planned output. - GSTX was recently awarded a $45 million California Competes Tax Credit for solar materials projects. - The tax credit depends on GSTX meeting certain investment and employment milestones. - GSTX includes majority- and wholly owned companies operating under the Quartz & Silicon Materials brand in the U.S., Australia, New Zealand and Europe. - GSTX is headquartered in Phoenix, Arizona. - The company’s website is More information.

Between the lines: - The OTCQB listing can help GSTX tell a broader capital-markets story while it works through the more uncertain parts of manufacturing scale-up. - The combination of a planned equity-linked financing, an offtake deal and a state tax credit suggests GSTX is trying to reduce execution risk around its factory buildout. - The company’s forward-looking claims depend on capital access, permitting, equipment availability, supply chains and customer performance, among other factors.

What's next: - GSTX will continue pursuing its private note offering and the development of its San Diego wafer operations. - The company will need to maintain OTCQB eligibility while working toward operational milestones. - Any California Competes Tax Credit benefit will depend on GSTX meeting the required investment and hiring targets. - A future Nasdaq listing remains a stated goal, but it will depend on the company meeting exchange requirements and sustaining progress.
