Graphite One Supports EIS Pathway for America's Largest Known Natural Graphite Deposit; No Anticipated Delay to 2029 Graphite Creek Project Startup as U.S. Remains 100% Import Reliant for Natural Graphite PR Newswire Comprehensive Review Supported to Address Stakeholder Concerns Anthony Huston, President and CEO: "Our team has been preparing for this level of review throughout the process, and we remain confident in our ability to deliver this critical domestic graphite supply chain project on our targeted 2029 timeline. We are pleased with the efforts of FAST 41 and USACE to maintain a completion date that is only two (2) years from the original date of filing." VANCOUVER, BC , July 9, 2026 /PRNewswire/ - Graphite One Inc. (TSXV: GPH) (OTCQX: GPHOF) (" Graphite One " or the " Company "), a developer of a complete U.S.-based advanced graphite supply chain, today announced that, following collaborative work with the U.S. Army Corps of Engineers (" USACE ") during the Environmental Assessment (" EA ") process, it has been determined that an Environmental Impact Statement (" EIS ") is the best option for all parties to progress the permitting effort for the Graphite Creek deposit. Graphite One concurs with this determination and reiterates its commitment to a public comment process that ensures that all voices are heard and that stakeholder concerns are comprehensively addressed.

The Company has been conducting all permitting work at the level required for an EIS from the outset and has maintained a startup schedule structured to allow for the timely completion of an EIS. Graphite One anticipates that the EIS schedule will align with State of Alaska permitting requirements and does not expect any delay to the proposed 2029 production startup date for the Graphite Creek Project. The Company appreciates the continued support of both the FAST-41 program and USACE in facilitating the completion of the EIS on schedule while thoroughly addressing all comments and concerns associated with the project.

"We fully support the Army Corps' recommendation to conduct a comprehensive EIS review. This approach ensures transparency and provides the opportunity for all stakeholders—including local communities, Indigenous groups, and regulatory agencies—to have their voices heard and concerns addressed in a thorough manner," said Anthony Huston, President and CEO of Graphite One. "Our team has been preparing for this level of review throughout the process, and we remain confident in our ability to deliver this critical domestic graphite supply chain project on our targeted 2029 timeline.

We value the partnership with the Army Corps and FAST-41 as we work together to responsibly develop America's largest graphite deposit." Leadership from Bering Straits Native Corporation (" BSNC "), the regional Alaska Native Corporation that made a significant direct investment in Graphite One in 2023, have also signaled their support for a full EIS review of the Graphite Creek Project. Many residents in the communities closest to the project are BSNC shareholders. "We agree that evaluating the Graphite Creek Project under the full EIS process is in the best interest of everyone involved, Graphite One, investors like BSNC, and most importantly, our shareholders who call the areas near the project home,"   said BSNC President Cindy Towarak Massie.   "Moving forward with an EIS is a more comprehensive approach.

It provides additional regulatory clarity for Graphite One's investors and more opportunities for those living near the project, whose families have subsisted on the Seward Peninsula for thousands of years, to have their concerns addressed." The Graphite Creek Project, located on the Seward Peninsula in Alaska, has been confirmed by the U.S. Geological Survey as America's largest known natural graphite deposit and is a cornerstone of U.S. efforts to establish a secure, vertically integrated domestic supply chain for battery-grade anode materials and other advanced forms of graphite for a range of technology applications. The project supports national priorities for critical minerals independence, supply chain resilience, and the growth of the electric vehicle, energy storage, and defense sectors. About Graphite One Inc. GRAPHITE ONE INC. continues to develop its Graphite One Project (the " Project "), with the goal of becoming an American producer of high-grade anode materials that is integrated with a domestic graphite resource.

The Project is proposed as a vertically integrated enterprise to mine and process natural graphite and to manufacture artificial and natural graphite anode active materials primarily for the lithium-ion electric vehicle battery and energy storage markets.
