Rover Group, Inc. (ROVR), a pet services marketplace platform, completed its SPAC merger with Nebula Acquisition Corporation in August 2021, with True Wind Capital serving as sponsor, and began trading on Nasdaq in the consumer technology and pet care sector. In February 2024, Rover filed a DEFA14A — definitive additional proxy materials — with the SEC, supplementing earlier proxy disclosures in connection with the company's pending go-private transaction with Blackstone, which had announced a definitive agreement to acquire Rover in late 2023. The DEFA14A filing represents one of several SEC submissions in the lead-up to the shareholder vote on that transaction.
