Red Herring Prospectus
A Red Herring Prospectus is a preliminary prospectus filed with the SEC as part of an IPO registration statement that includes substantially all material disclosures about the issuer but omits the final offering price, the number of shares to be sold, and other pricing-related terms that are finalized only at the close of the book-building process.
The name Red Herring derives from the bold red-ink legend that appears on the cover page of the document, historically stating that the registration statement has been filed with the SEC but has not yet become effective, that the securities described may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective, and that the document does not constitute an offer to sell. The red ink legend distinguishes the preliminary prospectus from the final statutory prospectus that is delivered to investors completing purchases.
The Red Herring Prospectus — formally the preliminary prospectus or the preliminary prospectus supplement in the context of a shelf takedown — serves as the primary disclosure document during the IPO roadshow. Management teams travel to meet institutional investors and present the business while investors review the preliminary prospectus to assess the offering. At this stage, the price range for the offering is typically included (often expressed as a range, such as $18.00 to $21.00 per share), but not the final price.
The Red Herring contains the full risk factors section, business description, management discussion and analysis (MD&A), financial statements, description of the securities being offered, use of proceeds, dilution analysis, and underwriting arrangements. These disclosures are substantially complete because under SEC rules the preliminary prospectus must be sufficiently detailed to constitute an adequate disclosure document for investors conducting due diligence.
After the roadshow, the underwriters and issuer determine the final offering price and number of shares based on the book of investor demand. The final prospectus (sometimes called the statutory prospectus) is then filed with the SEC, completing or supplementing the registration statement with the final terms. This filing triggers the effectiveness of the registration statement if it has not already been declared effective by the SEC.
Institutional investors rely heavily on the Red Herring during the bookbuilding period. Analysts at investing institutions use the document for financial modeling, risk assessment, and comparable-company analysis. The document becomes a permanent part of the public record on EDGAR and forms the legal basis for investor remedies under Section 11 of the Securities Act if material misstatements or omissions are later alleged.
