RMG Acquisition Corp. completed its de-SPAC merger with Romeo Power, Inc. in December 2020, with the combined company trading on the New York Stock Exchange under the ticker RMO. The blank-check company, sponsored by RMG Sponsor LLC and led by principal Robert Mancini, raised capital through a 2020 IPO targeting the clean-energy and electric-vehicle sector. Romeo Power developed lithium-ion battery packs and energy-storage systems for commercial electric vehicles. The company filed a Form 15-12G on October 28, 2022, initiating the termination of its Exchange Act registration, consistent with BorgWarner Inc.'s completed acquisition of Romeo Power that same month, which effectively took the company private.
