Decarbonization Plus Acquisition Corporation III (DCRCU) operates as a blank check company, or special purpose acquisition company (SPAC), formed to effect a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. The company targets opportunities in industries advancing global decarbonization, including renewable energy, sustainable infrastructure and low-carbon technologies; it offers redeemable units comprising one Class A ordinary share and one-third of a redeemable warrant, enabling investors to participate in its search for and pursuit of a target business combination. Sponsored by affiliates of Riverstone Holdings LLC and leveraging the Riverstone platform for deal sourcing, it focuses on sectors providing attractive risk-adjusted returns aligned with decarbonization objectives. Incorporated in Delaware in January 2021 and headquartered in New York, it completed a $350 million initial public offering of 35 million units in March 2021, listed on Nasdaq under DCRCU; formerly known as Silver Run Acquisition Corporation III, it rebranded in August 2020 to reflect its decarbonization focus. In December 2021, the company completed a business combination with Solid Power, Inc., an all-solid-state battery developer, through a reverse merger, resulting in Solid Power listing on Nasdaq under SLDP with DCRC units transitioning to represent Solid Power securities; as of late 2025, DCRCU units maintain limited trading activity on Nasdaq, reflecting post-merger dynamics with no further SPAC combinations announced.
