Graphite One Welcomes Pentagon Report Endorsing Tax Credits and Allied IP Licensing to Build U.S. Battery Equipment Manufacturing Capacity

CEO: "Graphite One welcomes the Pentagon's pragmatic recommendations for targeted tax credits, co-investment mechanisms, and the establishment of a framework for licensing established non-core manufacturing technologies to rebuild domestic battery equipment manufacturing"

VANCOUVER, BC , June 4, 2026 /PRNewswire/ - Graphite One Inc. (TSXV: GPH; OTCQX: GPHOF) ("Graphite One" or the "Company") today welcomed the release of a new Pentagon report recommending the creation of targeted production and investment tax credits, a co-investment fund, and the establishment of a framework for licensing established non-core manufacturing technologies from allied nations' suppliers for equipment used to manufacture advanced batteries.

The report, developed with the interagency Federal Consortium for Advanced Batteries as reported by POLITICO (click here), represents a significant policy signal supporting the build-out of domestic capabilities in a sector currently dominated by Asian suppliers (92% market share). It warns that reliance on foreign-produced battery-making equipment — including mixing machines, coating and drying systems, electrode stacking machines, and testing devices — creates critical vulnerabilities for U.S. military vehicles, drones, grid storage, and AI data center applications. The study estimates these efforts could create 5,000 new American jobs and access a global market projected to reach US$48 billion by 2032.

"Graphite One welcomes the Pentagon's pragmatic recommendations for targeted tax credits, co-investment mechanisms, and establishing a framework for licensing established non-core manufacturing technologies to rebuild domestic battery equipment manufacturing," said Anthony Huston, President and CEO of Graphite One. "The report correctly identifies that secure anode active materials ("AAM") are the indispensable foundation of any resilient U.S. battery supply chain — exactly the role Graphite One is fulfilling by developing America's largest graphite deposit in Alaska alongside large-scale AAM production in Ohio. Policies that reward total cost of ownership, create demand signals for U.S.-made equipment, and enable smart partnerships with allies will accelerate the onshoring of critical processing capacity, create thousands of American jobs, and end our dangerous 100% reliance on foreign adversaries for graphite."

The Pentagon report notes that it is currently "impossible to assemble a complete battery production line domestically without using some level of foreign-produced equipment" and recommends conditioning federal grants and loans for battery production on requirements that facilities use a percentage of U.S.-manufactured equipment, creating a "guaranteed demand signal" for domestic suppliers. It also encourages licensing agreements and joint ventures with allied suppliers for established technologies, with government support to vet partners and protect U.S. interests.

These recommendations align closely with Graphite One's ongoing development of its Ohio AAM facility, where specialized high-temperature graphitization, purification, and processing equipment will be required. The Company has already secured a site in Ohio and is advancing offtake discussions, power agreements, and equipment procurement planning alongside its Graphite Creek mine development, which is a FAST-41 covered project. Graphite One has received strong bipartisan U.S. Government support, including EXIM Bank non-binding Letters of Interest exceeding US$2 billion, prior Department of Defense Title III and Defense Logistics Agency funding totaling US$42 million, and inclusion on the FAST-41 permitting dashboard. "The Trump administration's extension of tariff exemptions for imported battery-making equipment until at least November 2026 recognizes the current reality while the domestic industry scales," Huston added. "Graphite One is committed to prioritizing secure, high-quality supply chains and will actively explore domestic and allied equipment solutions as they become available, consistent with the total-cost-of-ownership and supply security principles the Pentagon report champions."

Graphite One remains focused on delivering a complete, adversary-free U.S. graphite-to-anode supply chain that supports electric vehicle, energy storage, AI data centres, and defense applications while creating high-value jobs in Alaska and Ohio.

Graphite One's Domestic Supply Chain Strategy

The United States is currently 100% import-dependent for natural graphite, Graphite One is developing a fully integrated U.S.-based supply chain anchored by the Graphite Creek deposit – recognized by the U.S. Geological Survey as the largest graphite deposit in the U.S. and among the largest globally.  The strategy includes:

• Mining at Graphite Creek (Alaska)
• Transport via the Port of Nome
• Processing into advanced graphite and anode materials in Ohio
• Potential co-located recycling facility to recover graphite and other battery materials

This integrated approach positions Graphite One to become a cornerstone supplier in a domestic, circular battery materials economy.

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 active anode materials primarily for the lithium‐ion electric vehicle battery and energy storage markets.
