Decarbonization Plus Acquisition Corporation, the Riverstone Holdings-backed SPAC that brought hydrogen fuel cell commercial vehicle maker Hyzon Motors to Nasdaq under ticker HYZN, is completing its exit from public markets. The vehicle IPO'd in 2020 targeting the clean energy and zero-emission transportation sector, and closed its business combination with Hyzon in 2021. On March 13, 2025, HYZN filed a Form 15-12G with the SEC, formally initiating the termination of its Section 12(g) registration and ending its obligations as a public reporting company. The deregistration marks the close of the post-merger entity's life as a listed issuer.
