Benson Hill, Inc. completed its transition to a publicly traded company through a merger with Star Peak Corp II (Nasdaq: STPC), a blank-check vehicle sponsored by Star Peak Capital Management LLC. Star Peak Corp II conducted its initial public offering in early 2021, targeting the agriculture technology and food innovation sector. The business combination closed in September 2021, with Benson Hill — a crop science company focused on developing plant-based food ingredients through its proprietary CropOS technology platform — becoming the surviving public entity. The S-1/A amendment filed with the SEC on April 28, 2022 reflects post-merger registration activity as the combined company maintained its reporting obligations.
