The SEC alleged that: "Hyzon Motors, Inc., a publicly traded company that assembles hydrogen fuel cell electric vehicles ("FCEVs"), made false and misleading statements to investors about its customer and supplier relationships and overstated the number of FCEVs it had completed, delivered, and sold."

On September 27, 2023, the SEC "announced settled fraud charges against Hyzon Motors Inc., an upstate New York-based company that builds hydrogen fuel cell electric vehicles (FCEVs), for misleading investors about its business relationships and vehicle sales before and after a July 2021 merger with a publicly-traded special purpose acquisition company, or SPAC. The SEC also charged Craig M. Knight, Hyzon's former CEO, and Max C.B. Holthausen, former managing director of Hyzon's European subsidiary, for their roles in the fraudulent scheme."

On January 16, 2024, the Court issued a final judgment stating that "Defendant Hyzon Motors Inc. . . . consented to the Court's jurisdiction over Defendant and the subject matter of this action; consented to entry of this Final Judgment without admitting or denying the allegations of the Complaint (except as to jurisdiction); waived findings of fact and conclusions of law; and waived any right to appeal from this Final Judgment."
