Rosen Law Firm Investigates Hyliion Holdings Corp. Securities Claims

The Rosen Law Firm, an international investor rights law firm, has initiated an investigation into potential securities claims against Hyliion Holdings Corp. The investigation stems from allegations that Hyliion may have disseminated materially misleading business information to the investing public.

The inquiry follows a short-seller report published on June 23, 2026, by Pelican Way Research, which questioned the validity of a key customer agreement. Following the news of this report, Hyliion's stock price declined by 17.2% on the same trading day.

Rosen Law Firm is encouraging any investors who purchased Hyliion securities to contact them for information regarding the potential class action. The firm emphasizes that investors may be entitled to compensation without out-of-pocket fees, operating on a contingency fee basis. The law firm has experience in handling such securities litigation and is seeking investors to join the prospective class action.

The firm, which focuses on securities class actions and shareholder derivative litigation, advises investors to select experienced counsel. Further details regarding the Hyliion investigation can be found on the firm's website, and interested parties are encouraged to reach out directly.
