Form S-3
Also known as: S-3 · shelf registration
DEFINITION
S-3 is available to seasoned public companies that meet eligibility tests (timely reporting history, minimum public float). It lets them register securities for future sale and 'shelf' them — pulling them down to market via a 424B prospectus supplement when conditions are favorable. WKSI filers get automatic effectiveness on filing.
WHY IT MATTERS FOR RETAIL INVESTORS
An S-3 filing by a company you own usually means dilution is coming — they are reserving the right to issue new shares. The size relative to market cap matters more than the act of filing itself. A 'universal shelf' for ATM (at-the-market) offerings is especially dilutive over time. Pair the S-3 with later 424B filings to see what was actually issued.
