A company planning a US IPO registers its shares on Form S-1 (foreign companies use F-1). The S-1 holds the prospectus: business, risks, financials and how the money will be used. Amendments (S-1/A) follow as the SEC comments and the price range is set.
The IPO API adds the terms: price range, shares offered and underwriters.
