Milestone expands investor visibility and market access as GSTX advances its U.S. silicon wafer manufacturing strategy and capital-markets profile.

Graphene & Solar Technologies Limited (OTCQB:GSTX)

PHOENIX, AZ, UNITED STATES, September 16, 2026 /EINPresswire.com/ -- Graphene & Solar Technologies Limited (OTCQB: GSTX) (“GSTX”) today announced that its common stock has been approved for trading on the OTCQB^® Venture Market, with trading having commenced on September 15, 2026, under its existing ticker symbol, “GSTX.”

The uplisting follows OTC Markets Group’s approval of GSTX’s application, which required GSTX to satisfy the OTCQB Venture Market’s financial, reporting, verification, and market-eligibility standards, which exceed those of the OTCID Basic Market.

“Uplisting to OTCQB is an important step forward on our company’s journey to a potential future listing on the Nasdaq Stock Market, while also strengthening the capital-markets platform around our U.S. silicon wafer manufacturing strategy,” said Jason May, executive chairman and CEO of GSTX. “We believe OTCQB quotation will enhance our visibility in the investment community by providing greater market awareness, expanded reach to institutional and retail investors, and potentially increased trading liquidity.”

This market-tier upgrade complements GSTX’s ongoing capital-formation efforts. As previously announced, GSTX is conducting a private offering of up to $40 million of convertible notes and intends to use the net proceeds of the offering, if completed, to support the development of its U.S. silicon wafer manufacturing operations.

The convertible notes have not been registered under the Securities Act of 1933, as amended, or any state securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This press release does not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful.

Through its U.S. subsidiary, Quartz & Silicon Materials Company Limited (“QSM USA”), GSTX’s near-term focus is the planned production of silicon wafers in San Diego, California. When fully operational, the existing industrial facility is expected to provide up to 10 GW of wafer capacity annually. QSM USA has entered into a long-term offtake agreement with a U.S. solar manufacturer for 30 percent of this planned output. GSTX was also recently awarded a $45 million California Competes Tax Credit for its solar materials projects, the realization of which is subject to GSTX’s satisfaction of certain investment and employment milestones.
