Prospectus Delivery Requirement

The Prospectus Delivery Requirement is the Securities Act framework governing when a final Section 10(a) prospectus must be delivered or made available in connection with a registered securities sale.

Updated 2026-09-02 · Foundation

How it works

Modern SEC rules use an access-equals-delivery model for many registered offerings. Rule 172 can satisfy specified Section 5(b)(2) prospectus-delivery obligations when the Registration Statement is effective, no disqualifying proceeding is pending and the issuer has filed, or makes a good-faith reasonable effort to file, a Section 10(a) prospectus within Rule 424 timing. Rule 173 generally requires an underwriter or dealer to provide the final prospectus or a notice of registration within two business days after completion of the sale in covered transactions.

Section 5 creates the delivery framework

Registered sales remain tied to a prospectus satisfying Section 10(a), even though SEC rules can alter how the obligation is satisfied.

Rule 172 uses access rather than physical delivery

When its conditions are met, carrying or delivering the security does not require the paper prospectus to precede or accompany the security.

Rule 173 adds post-sale notice

Covered underwriters and dealers generally provide the prospectus or a notice of registration no later than two business days after completion of the sale.

Exclusions still exist

Rule 172 does not apply to specified investment-company, business-combination, Form S-8 and registered non-variable-annuity offerings.

Worked example: electronic access

A final prospectus is timely filed on EDGAR and publicly accessible. The broker sends the investor a confirmation and the Rule 173 notice rather than mailing a thick paper prospectus before settlement.

Why the rules matter operationally

They permit modern electronic distribution without abandoning the legal requirement that final registered-offering disclosure be publicly available.

Common mistakes

Assuming prospectus delivery always means paper delivery; believing Rule 172 eliminates the final prospectus; ignoring Rule 173 notice; and applying access-equals-delivery to excluded transactions.

Example

An investor purchases shares in a registered public offering. Rather than receiving a paper final prospectus before the security is delivered, the transaction can rely on Rule 172 if its conditions are satisfied, while the dealer sends the required Rule 173 notice within the applicable period.

Professional note

The phrase “prospectus delivery” can be misleading if read literally. Current rules often focus on SEC filing, public access and notice rather than physical delivery of the full final document.
