Summary of the Action

Defendants made false and/or misleading statements and/or 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) Thomas Healy, the Company's Chief Executive Officer (CEO), and Jon Panzer the Company's Chief Financial Officer (CFO), timed the announcement and foregoing price appreciation to insider trade; and (3) as a result, defendants' statements about Hyliion's business, operations, and prospects, were materially false and misleading and/or lacked a reasonable basis at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages.
