The complaint filed by Robbins LLP centers on a May 12, 2026, announcement regarding a letter of intent between Hyliion and VFG Holdings LLC. While the deal initially drove Hyliion’s stock price upward, the lawsuit alleges that the agreement was a facade designed to inflate share values. Plaintiffs contend that internal executives capitalized on this artificial appreciation by selling significant portions of their holdings shortly after the announcement.

Scrutiny intensified on June 23, 2026, when a report from Pelican Way Research challenged the legitimacy of VFG Holdings. The research firm noted that VFG was incorporated only months prior, lacked visible business operations, and maintained minimal digital presence. Following the report, Hyliion stock plummeted more than 17% in a single session, followed by an additional 19.3% decline the next day to close at $4.92 per share.
