SEC Form S-1

Definition

SEC Form S-1 is the initial registration form for new securities required by the SEC for public companies that are based in the U.S. Any security that meets the criteria must have an S-1 filing before shares can be listed on a national exchange, such as the New York Stock Exchange. Companies usually file SEC Form S-1 in anticipation of their initial public offering (IPO). Form S-1 requires companies to provide information on the planned use of capital proceeds, detail the current business model and competition and provide a brief prospectus of the planned security itself, offering price methodology and any dilution that will occur to other listed securities.
