Supernova Partners Acquisition Company III, Ltd. (STRE-WT) operates as a blank check company whose sole purpose centers on effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses, primarily targeting technology sector companies focused on internet, consumer, media, and related industries; it offers no other products or services beyond this SPAC structure, including redeemable warrants (traded as STRE WS or STRE+), each exercisable for one Class A ordinary share at $11.50. Founded in 2020 and headquartered in Washington, District of Columbia, the company conducted its initial public offering in March 2021, raising $250 million through 25 million units at $10 each via underwriters J.P. Morgan and Jefferies, with leadership from figures such as CEO Robert D. Reid and co-chairs Spencer Rascoff and Alexander Klabin. In a major development, it redeemed all outstanding public shares at approximately $10.20 per share effective March 27, 2023, after failing to complete a business combination within the required timeframe, leading to voluntary delisting from the NYSE, cancellation of public shares, and expiration of warrants as worthless, with the sponsor waiving redemption rights on founder shares; no subsequent mergers, acquisitions, funding, or operational shifts have occurred as the entity became defunct.
