Form S-1
Also called: S-1, S-1/A, Form F-1, F-1, resale S-1
The full-length SEC registration statement used for IPOs and by companies that cannot use a shelf, including to register shares for resale.
Explanation
Form S-1 is the default registration form for US issuers, with the full disclosure package: business, risk factors, MD&A, audited financial statements, executive pay and the offering terms. Foreign private issuers use the equivalent Form F-1. The SEC staff may review it and issue comments, which the company answers with amendments (S-1/A), and nothing can be sold until the SEC declares it effective (an EFFECT notice on EDGAR).
Companies use an S-1 for an IPO, and later whenever they cannot use a short-form S-3 shelf: for example, if they have been public for less than a year, filed a report late in the last 12 months, or trade only over the counter with less than $75 million of float. Small caps in that position often run best-efforts S-1 offerings of shares plus warrants.
Many S-1s are resale registrations: they register shares that PIPE investors or an equity-line investor already own or will buy, so those holders can sell. The company gets no money from a resale S-1, but the shares it covers can reach the market as soon as it is effective.
Why it matters
A pending S-1 from a small cap is a strong sign that an offering is coming soon; amendments that add a price, an underwriter or a share count mean it is close.
How Equity Dictionary measures it
A pending S-1 or F-1 sets shelf and registration readiness to 85 out of 100, higher than an ATM, because a deal is already in registration. Resale registrations are classified as resales, not raises, and S-8 employee-plan registrations are never counted as raises.
