Bronstein, Gewirtz & Grossman, LLC announced on Aug. 30, 2026, that a securities class action has been filed against Hyliion Holdings Corp. (NYSE: HYLN) and certain officers on behalf of investors who purchased or acquired Hyliion securities between May 12 and June 23, 2026, inclusive. The complaint alleges that defendants made false or misleading statements, or failed to disclose that a deal was announced with a very recently formed entity that does not appear to have actual business operations, and that Chief Executive Officer Thomas Healy and Chief Financial Officer Jon Panzer timed the announcement and resulting share-price appreciation to facilitate insider trading. The notice follows related investor actions, including a Rosen Law Firm class action covering the same period and an earlier suit in the U.S. District Court for the Western District of Texas focused on Hyliion’s partnership with VFG Holdings and an approximately $133 million proposed transaction. After Pelican Way Research questioned VFG’s capabilities on June 23, Hyliion shares fell from $7.37 to $6.10, or about 17%, then dropped another 19% to $4.92 on June 24. Investors have until October 27, 2026, to seek lead-plaintiff appointment; participation in any recovery does not require serving as lead plaintiff.
