Velodyne Lidar, Inc. filed this Form 10-Q in November 2019, roughly nine months before announcing its business combination with Graf Industrial Corp., a blank-check company sponsored by Graf Industrial Holdings LLC that conducted its initial public offering on the New York Stock Exchange in 2018 under the ticker GRAF. The filing predates the deal's close in September 2020, which brought Velodyne's lidar sensor and autonomous-vehicle technology portfolio to public markets on Nasdaq under the ticker VLDR. Graf Industrial operated in the industrials and advanced-technology sector, targeting companies at the intersection of sensing hardware and mobility. The combined entity remained publicly traded until early 2023, when Velodyne merged with rival lidar manufacturer Ouster, Inc.
