Form 424B4 Filings

What Is SEC Form 424B4?

SEC Form 424B4 is a prospectus filed under Rule 424(b)(4) of the Securities Act of 1933. It is used to submit a final prospectus containing pricing and other information omitted from, or incorporated by reference into, a registration statement at the time it becomes effective. The filing reflects the definitive terms of a registered offering, including the final public offering price, underwriting discounts and commissions, proceeds to the issuer, and other offering-specific details.

Form 424B4 supports transparency by ensuring that the final prospectus being used in connection with a registered offering is publicly accessible. Here is an example of a prospectus filed pursuant to Rule 424(b)(4).

Key elements typically found in SEC Form 424B4 include:

• Name of the issuer and the securities being offered
• Offering price and underwriting discounts or commissions
• Use of proceeds and offering terms specific to the transaction
• Risk factors and required offering disclosures presented in the prospectus
• Underwriting arrangements and distribution details
• References to the applicable registration statement and effectiveness

For domestic issuers, a final Form 424B4 prospectus may follow a registration statement such as Form S-1, allowing investors to compare the original registration disclosure with the final pricing and offering terms.

SEC Form 424B4 Filing Deadlines

SEC Form 424B4 is filed on an offering-driven basis after a registration statement becomes effective. Timing generally follows Rule 424 requirements and is tied to the earlier of the determination of the offering price or the first use of the prospectus after effectiveness.

Foreign private issuers may similarly file a final prospectus following a registration statement such as Form F-1, providing definitive pricing and transaction information for a registered U.S. securities offering.
