Pomerantz LLP announced a securities class action against Hyliion Holdings Corp. for investors who purchased or otherwise acquired the company’s securities from May 12 through June 23, 2026. The lawsuit concerns whether Hyliion and certain officers or directors committed securities fraud or other unlawful business practices. The notice follows a June 23 Pelican Way Research report that questioned Hyliion’s non-binding letter of intent with VFG Holdings for up to 250 KARNO Cores, representing about $133 million in potential revenue. Pomerantz said Hyliion shares fell $1.27, or 17.2%, to $6.10 that day. Investors have until Oct. 27, 2026, to seek lead-plaintiff appointment.
