Graphene & Solar Technologies Ltd (GSTX) is a materials manufacturing company that produces high-purity quartz sand, silicon, polysilicon, and silicon wafers for the solar and semiconductor markets. Revenue is intended to come from direct product sales of these critical materials to solar and semiconductor customers, though as of the 10-K filed 2026-02-25, the company was in a pre-revenue, development-stage phase, with manufacturing samples planned for customer validation and presales activity. GSTX has established or acquired a portfolio of businesses built around advanced manufacturing of materials classified as critical minerals by governments in the United States and other jurisdictions. The company plans to grow its workforce to a minimum of 30 full-time and part-time employees and contractors within 12 months of the filing, subject to securing additional funding. Operations and personnel are distributed across Australia, Central Europe, and the United States. Management has cited proposed U.S. import duties on solar equipment from China and Southeast Asia as a potential demand driver for domestic production.
