The Company hosted Congressman John Carter (TX-31), congressional staff, industry leaders, and strategic partners for the first full tour of its Austin-based operations, graphene development and manufacturing hub. The new headquarters reflects HydroGraph’s commitment to expanding U.S. production capacity for pristine graphene at a time when demand is growing across the defense, energy, infrastructure, aerospace and advanced manufacturing sectors. The Austin facility is designed to provide up to 30 tons per year of pristine graphene production capacity to support HydroGraph's commercialization and customer engagement efforts across a range of industrial applications. “Central Texas has always been a place where big ideas become real-world solutions,” said Representative Carter. “I'm pleased to welcome HydroGraph home to Texas, where they can continue their innovative research, support America's warfighters and make an immense impact on the aerospace, infrastructure and advanced manufacturing industries.” Separately, the Company continues development of its recently announced commercial-scale <a href="https://www.globenewswire.com/Tracker?data=n0l68E69bgWKHrYxWcCMB0dEu8K_5k0dKXW3tK5NGRR5Yv6gSQecB4SVySkgxTKF0C2-AC-WwJjEIUoiB0FXHuoITvJCxkQhxYEiBAoxA_ZgZ0DuuFIT6qKuvzvmFP7I7fyD3ltBkQq2wvqkscMfaxD3cks370XlnEyhzRMcF9iX10wsnRDaNSAAL6tVaM45ku2JKGogojHzUUdplvs-AQ==" rel="nofollow" target="_blank" title="">Bellville, Texas manufacturing facility</a>, expected to begin operations in 2027. By producing graphene in Texas using hydrocarbon feedstocks, HydroGraph aims to support the development of a more resilient domestic supply chain for advanced materials. The expanded manufacturing platform is intended to support customer demand across a range of markets, including defense, energy storage, infrastructure, composites, advanced manufacturing, and other industrial applications. As governments increasingly prioritize resilient domestic supply chains for critical materials, graphene is expected to play an important role in advanced manufacturing and national security applications1. HydroGraph has increased its federal focused advocacy throughout 2026 and <a href="https://www.globenewswire.com/Tracker?data=3tN1kkF8vOLkiKaGi3HXs7TNVjdEA2AtkMLNnffkzEHceHZwdogrjXzoH1V9oMGUqoCeVIZ-jnb0TG7Nd535R0YiTsJj0uYPuvKnJK_n5oCGn7Xe5vyDnBeGBDwpRlSsTSbs3lS2NAjUJN04UW_Yfv8_GxBLYDCn1vBMD09ItALf6y6vvHf7nBP6Z5cbiCCVoo57kujpMOlTJm2TnxsEMFvTu9CgRKgUPCpd1k7HlnLX-sIUNj07nNypYroIhQ0CX9xWspA4ZAvYyGHPFFW6Xw==" rel="nofollow" target="_blank" title="">recently called on the U.S. government to designate graphene a critical material</a> under the Defense Production Act. Doing so would recognize the advanced material’s potential importance to defense manufacturing and other strategic industries and ensure prioritization of domestic supply as a matter of national interest. HydroGraph’s proprietary <a href="https://www.globenewswire.com/Tracker?data=cPqJd4BayXs_wqk58_XNtQarnyl5QQTDMHsPvSSEIl-5WLyeqfK482Smn9HpCedamkCVgOlCR7mq7d-iGmi28rskakceEpAdCpj6ALMrIi_Y6pc6KsuQimv0aZ37Uru2" rel="nofollow" target="_blank" title="">Hyperion Reactor™ technology</a> uses a patented detonation synthesis process to convert hydrocarbon gases into graphene. The cost- and energy-efficient modular manufacturing platform is designed to deliver ultra-high purity, consistent quality, and commercial scalability while eliminating graphite as the starting material. “The United States is seeing increasing investment in advanced materials manufacturing, and HydroGraph intends to be a leader in supplying the ultra-pure graphene that next-generation industries require. Our investment in Texas positions HydroGraph to meet growing demand while helping establish a secure domestic supply chain for advanced graphene materials,” said Kjirstin Breure, President and Chief Executive Officer of HydroGraph. During the tour, Congressman John Carter previewed HydroGraph’s manufacturing process and met with HydroGraph’s leadership to discuss the role advanced materials can play in strengthening the U.S. defense industrial base, supporting American manufacturing, and reducing dependence on foreign-controlled supply chains. Currently, much of the world’s graphene production depends on graphite sourced overseas, and in particular China2. HydroGraph’s manufacturing process takes a different approach. Instead, the Company’s technology converts domestically sourced hydrocarbon feedstocks directly into pristine synthetic graphene, creating a domestic production capability that supports supply chain resilience and long-term industrial competitiveness. The opening of HydroGraph’s Texas headquarters and continued development of its Bellville manufacturing facility mark important milestones in the Company's strategy to build one of North America’s leading commercial graphene production platforms. About HydroGraph HydroGraph is a leading producer of pristine graphene using its proprietary <a href="https://www.globenewswire.com/Tracker?data=cPqJd4BayXs_wqk58_XNtWXMQgs5O1R_HEDaOm8n_oGynSIh2J8UnK-bOpwDni0ztxAnXG6Xcrvq1xw8UiZbOY2E1oq6N3fkzOLpLbKASVY=" rel="nofollow" target="_blank" title="">Hyperion Reactor</a> technology, which allows for ultra-high purity, low energy use, and uniform batches. The quality, performance, and consistency of HydroGraph’s graphene follow the Graphene Council’s Verified Graphene Producer® standards, of which very few graphene producers are able to meet.
