Prospectus (S-1 Filing)
A prospectus is the official disclosure document a company must file with the SEC before conducting a public offering, with the S-1 being the registration form used by domestic issuers for an initial public offering.
The prospectus is the foundational legal document of any public offering. It serves two functions simultaneously: it is the marketing document that describes the company to potential investors, and it is the legal disclosure document that satisfies the SEC's requirements under the Securities Act of 1933. The S-1 form is the standard registration statement used by U.S.-based companies conducting an IPO; foreign private issuers use Form F-1. Companies that are already public use different forms (S-3, S-4) for subsequent offerings.
The S-1 is filed electronically with the SEC and made publicly available on the EDGAR database. Before the SEC declares the registration effective, the company circulates a preliminary prospectus — colloquially called a red herring because of the red-ink disclaimer on its cover stating that the registration has not yet been approved — to gauge investor interest and solicit feedback. After SEC review and any required amendments, the final prospectus is filed with the definitive offering price and terms.
The content of a prospectus is comprehensive and standardized. It must include audited financial statements for the prior three fiscal years (or since inception for newer companies), a management discussion and analysis (MD&A) of financial results and liquidity, a detailed description of the business and its competitive environment, risk factors that could adversely affect the company or the value of the shares, information about the use of proceeds from the offering, and the compensation and equity holdings of senior executives and directors.
The risk factors section is particularly important for investors to read carefully. Companies are legally obligated to disclose any material risk that could affect the investment, and these sections can run to dozens of pages covering everything from competitive threats and regulatory risks to macroeconomic risks and dependence on key personnel. While risk factor language is often drafted to be broad and protective for legal purposes, a close reading can reveal genuine vulnerabilities specific to the company.
The JOBS Act of 2012 created a new category called Emerging Growth Companies (EGCs) — generally those with less than $1.07 billion in annual revenue in their most recent fiscal year — which are permitted to file a confidential draft S-1 with the SEC before going public. This allows the company to resolve SEC comments in private before the document becomes public, reducing competitive exposure during the preparation period.
