GreenLight Biosciences Holdings, PBC (Nasdaq: ENVI) traces its public listing to Environmental Impact Acquisition Corp, a blank-check company that completed its IPO in 2021 with Environmental Impact Acquisition Holdings LLC as sponsor. The SPAC targeted the environmental and sustainability sector before closing a de-SPAC merger with GreenLight Biosciences, an RNA technology company focused on biopesticide and human health applications, in early 2022. By early 2023, the combined entity announced a wind-down of operations amid capital constraints; the 8-K/A filed July 28, 2023 amends a prior current report submitted during that restructuring period.
