J-Star Holding Co. Ltd. (NASDAQ:YMAT) shares are experiencing a notable rise on Thursday, buoyed by anticipation of upcoming earnings and news of aggressive expansion plans. The company is scheduled to announce its first-quarter earnings on June 9, contributing to a strong premarket reaction. This surge follows a significant 18% correction on Wednesday, which came after an extraordinary nearly 200% rally earlier in the week. The volatility began when a subsidiary received approval from the Central Bank of Taiwan for a $60 million loan facility, aimed at financing a solid-state battery manufacturing line in Baytown, Texas. J-Star's CEO, Jonathan Chiang, emphasized that this financing marks a pivotal milestone for their U.S. expansion, with the facility expected to play a crucial role in the North American advanced energy supply chain. Currently, J-Star shares are trading at $1.16, reflecting a 2.65% increase during premarket trading, and are positioned above all major moving averages, indicating a positive trend shift.
