What happened?

On June 23, 2026, Pelican Way Research issued a report entitled "Hyliion: A Glorified Science Project Who Has Continuously Failed to Meet Expectations And Is Now Throwing Around A Meaningless Deal." The report alleged that a recent letter of intent the Company announced with VFG Holdings, LLC ("VFG") for a major deal "is a sham" because VFG "does not appear to have any substance," has a website that "contains just two pages" and appears to only have four employees. The report called into question whether VFG is an "AI data center integrator" capable of the deal previously announced by the Company.

On this news, the price of Hyliion stock fell $1.27 per share, or 17.2%, to close at $6.10 on June 23, 2026, thereby injuring investors. The following day, Hyliion stock fell another $1.18 per share, or 19.3%, to close at $4.92 on June 24, 2026, thereby injuring investors further.

What is the Hyliion Holdings Corp. lawsuit about?

Specifically, the complaint alleges defendants failed to disclose that: (1) in order to cause rapid price appreciation in Hyliion stock, Defendants announced a deal with an entity that was very recently formed and does not appear to have any actual business operations; (2) the Individual Defendants timed the announcement and foregoing price appreciation to insider trade; and (3) as a result, defendants' positive statements about Hyliion Holdings Corp.'s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.
