A securities class action against Hyliion Holdings Corp. covers investors who purchased or otherwise acquired the company’s securities from May 12 through June 23, 2026. Robbins LLP and Bernstein Liebhard LLP have issued investor notices concerning the case, which alleges Hyliion misled investors about a non-binding Letter of Intent with VFG Holdings LLC to provide power modules for data-center applications. The proposed arrangement involved up to 250 KARNO Cores, representing 50 MW of potential deployments over five years. Hyliion shares rose from $2.68 on May 12 to $4.67 on May 15 before falling $1.27, or 17.2%, on June 23 and another $1.18, or 19.3%, on June 24 to close at $4.92. The complaint alleges the company made materially false or misleading statements about its operations, growth prospects and financial stability, while earlier allegations focused on the VFG arrangement and alleged insider trading. Investors seeking lead-plaintiff appointment must act by October 27, 2026.
