Churchill III was formed in October 2019 as a blank check company. A blank check company is sometimes referred to as a special purpose acquisition vehicle, or "SPAC," and does not initially have any operations or business of its own. Rather, it raises money from investors in an initial public offering and then uses the proceeds from the offering to acquire a business or operational assets, usually from a private company that does not publicly report financial or operating results. As a result, investors in blank check companies rely on the skill, transparency, and honesty of the blank check company's sponsor to spend the offering proceeds to acquire a fundamentally sound target company that offers attractive risk-adjusted returns for investors.

On or about February 14, 2020, Churchill III completed its initial public offering, selling 110 million ownership units to investors for gross proceeds of $1.1 billion. Each unit was priced at $10 and consisted of one share of Class A common stock and one-fourth of one warrant to purchase Class A shares. Each whole warrant entitled the holder to purchase one share of Churchill III Class A common stock at $11.50 per share.
