Hyzon Motors Inc. (Nasdaq: HYZN) completed its business combination with Decarbonization Plus Acquisition Corporation, a blank-check vehicle sponsored by Riverstone Holdings that held its IPO in 2020, with the merger closing in July 2021. The company developed hydrogen fuel cell electric powertrains for commercial and heavy-duty transportation applications, targeting fleet operators across North America, Europe, and Australia. Following a 2023 settlement with the U.S. Securities and Exchange Commission over revenue recognition disclosures and subsequent operational setbacks, Hyzon initiated a wind-down of its business in late 2024; its March 2025 8-K filing reflects corporate activity during that dissolution process.
