Rule 430B
Rule 430B is an SEC rule allowing specified information to be omitted from certain shelf-registration prospectuses at effectiveness and later supplied through prospectus supplements or incorporated filings.
How it works
Rule 430B supports delayed and continuous offerings by eligible issuers. Depending on the type of shelf and issuer, the base prospectus can omit information such as whether the offering is primary or secondary, the plan of distribution, detailed security descriptions, selling-holder identities or other information not yet known. Later prospectus supplements and incorporated Exchange Act reports can add the transaction-specific information, and the rule governs when that information becomes part of the Registration Statement for liability purposes.
The rule is designed for shelf offerings
It operates with delayed or continuous offerings under Rule 415 rather than the conventional immediate-pricing structure addressed by Rule 430A.
Automatic shelves receive broad flexibility
An Automatic Shelf Registration Statement can omit specified transaction details that are not known at filing.
Secondary resales can receive tailored treatment
Eligible shelf registrations can omit selling-holder identities and amounts in specified circumstances until later disclosure.
Later disclosure becomes part of the liability framework
Rule 430B governs when information in prospectus supplements or incorporated reports is deemed included in the Registration Statement.
Worked example: unknown distribution method
A shelf is effective before the issuer decides whether a later offering will be underwritten, agency-based or another permitted distribution method. The final plan is supplied at takedown.
Why the rule matters to frequent issuers
It allows issuers to maintain market-ready registration capacity without pre-negotiating every future financing.
Common mistakes
Using Rule 430B for a conventional non-shelf IPO; assuming omitted information never needs to be disclosed; confusing shelf flexibility with exemption from registration; and treating a base shelf prospectus as the complete disclosure for every later offering.
Example
A Well-Known Seasoned Issuer files an Automatic Shelf Registration Statement covering common stock, debt and other securities without identifying a specific transaction. Months later, a Prospectus Supplement supplies the amount, price, underwriters and final terms of a debt offering.

Professional note
Rule 430B is central to shelf flexibility, but it is not permission to leave investors without required information when securities are actually sold. The missing terms are supplied later through the shelf disclosure system.
