The legal action centers on a June 23, 2026, market drop, where Hyliion shares plummeted 17.2%. The slide occurred after Pelican Way Research released a report challenging the legitimacy of a customer deal that had previously fueled a 150% rally in the company's stock price. Shareholders who suffered losses during this period are now being invited to join a prospective class action suit.

Rosen Law Firm, which operates on a contingency fee basis, is positioning itself to lead the litigation. The firm emphasizes its history of securing settlements, including a record-breaking result against a Chinese issuer and consistent top-tier rankings from ISS Securities Class Action Services. Interested parties are directed to the firm’s portal or contact Phillip Kim to participate in the recovery effort.
