Hyzon Motors Inc. (HYZN) was a hydrogen fuel cell commercial vehicle company that entered the public markets in 2021 through a SPAC merger with Decarbonization Plus Acquisition Corporation III, sponsored by Decarbonization Plus Acquisition Management III LLC, an affiliate of Riverstone Holdings, targeting the clean transportation and decarbonization sector. Hyzon designed and supplied zero-emission hydrogen-powered trucks for commercial fleet operators across North America, Europe, and Australia. Following regulatory scrutiny from the SEC and subsequent financial restatements after its listing, the company encountered sustained operational headwinds. On March 3, 2025, Hyzon filed a Form 25 with the SEC, initiating the voluntary delisting and deregistration of its securities, marking the close of its run as a publicly traded company.
