Strategic Initiatives
Growth programs, investments, and their expected impact
Developing a proposed 100 MWh modular, automated polymer-based solid-state battery manufacturing facility in Baytown, Texas, targeting the unmanned aerial vehicle (UAV), aerospace, defense, and advanced energy storage markets.
Expected impact: Establishes a high-density domestic battery supply chain for aerospace and defense contractors, diversifying J-Star's business away from traditional carbon fiber sports equipment.
Phasing out traditional OEM manufacturing activities and direct operations in China, including curtailing interests in four China-based entities, to reduce geopolitical risk exposure.
Expected impact: Improves working capital efficiency, lowers direct exposure to geopolitical tensions, and shifts corporate focus toward proprietary design, R&D, and intellectual property creation.
Leveraging third-party manufacturers for production while utilizing the company's proprietary raw materials and intellectual property, rather than maintaining heavy capital-intensive manufacturing facilities.
Expected impact: Designed to ensure highly competitive production costs, improve working capital efficiency, and enhance gross margins.
