Supernova Partners Acquisition Company III, Ltd. (NYSE: STRE-UN) is a blank check company focused on effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses; it does not have significant operations prior to completing such a transaction. The company targets businesses in the technology sector, particularly those in internet, consumer, media, and similar industries with large addressable markets and scalability potential. Incorporated in 2020 and headquartered in Washington, District of Columbia, it operates its sponsor activities through affiliates without specified geographic limitations beyond its U.S.-listed securities.
Its securities structure includes units comprising Class A ordinary shares and public warrants, with the units trading under the ticker STRE-UN on the New York Stock Exchange; upon separation, shares trade as STRE and warrants as STRE WS. The company raised approximately $250 million in its initial public offering in March 2021 at $10.00 per unit, led by bookrunners J.P. Morgan Securities LLC and Jefferies LLC, with leadership provided by Co-Chairs Spencer M. Rascoff and Alexander M. Klabin, CEO Robert D. Reid, and CFO Michael S. Clifton.
In March 2023, Supernova Partners Acquisition Company III announced the redemption of all its outstanding public shares effective March 27, 2023, and its voluntary delisting from the NYSE, with public shares cancelled thereafter and warrants expiring worthless; the sponsor waived redemption rights on founder shares. As of late 2025, units continue to trade actively around $10.19, indicating ongoing market presence amid a renewed SPAC market, though no business combination has been announced and the company remains in search of a target. No recent partnerships, acquisitions, funding rounds, or new product launches have been reported in the last 1-2 years.
