IPO registrations (S-1, F-1)

Companies going public, or registering any public offering of their own stock, file Form S-1 (or F-1 when foreign) with the SEC, then amendments as the SEC comments, a final prospectus (424B4 or 424B1) with the price once the deal is done, and the SEC posts a notice when the registration is declared effective. Here is every one of those filings in EDGAR’s index since 1993, grouped by company, with each company tied to its insiders, Form D offerings, nonprofits, state registrations, lobbying and other records on this site. Each filing links to EDGAR.

21,584 registrants (2,176 on Form F-1), 176,418 filings, 34,238 initial registrations from 1994 to 2026. 9,456 registrants filed a final prospectus, 4,758 asked to withdraw, 4,631 have a ticker today. 15,394 registrants are tied to 53,034 other records on this site.

Filings by year

An S-1 is not only an IPO: a company already public files one too when it registers a resale or a new class of stock, and the SEC also counts a 424B4 for any effective registration. The final prospectus and withdrawal columns count filings within two years of the company’s S-1 or F-1.

Ties to the rest of this site

Exact ties share a CIK (SEC insider filings, financial statements, Form D) or an EIN (nonprofits, state registrations, lobbying, Form 5500 plans, federal awards). Fuzzy ties share a name and state. People are the officers, directors and 10% owners on the company’s Forms 3, 4 and 5 who are linked to a person page.

What this covers, and what it doesn't

• Forms S-1, S-1/A, F-1 and F-1/A from EDGAR’s quarterly full index, 1993 to now, every filer. Shelf registrations (S-3), small-company offerings (Regulation A, Form 1-A), SPAC mergers on S-4 and registrations before EDGAR (1993, with full coverage from 1996) are not here.
• The final prospectus (424B4, 424B1), notice of effectiveness (EFFECT), Rule 462(b) add-ons (S-1MEF, F-1MEF) and withdrawal requests (RW) are included when filed between the company’s first S-1 or F-1 and two years after its last; a 424B4 for an unrelated shelf offering in that window is counted too.
• The offering terms (price range, shares, proceeds, underwriters) and the registrant’s financial statements are in the prospectus text and are not parsed yet. Company details (SIC, state of incorporation, address, EIN, tickers, former names) are what EDGAR holds today, not at the time of the filing.
• Ties to people and organizations on this site by name and state are marked Fuzzy; ties by CIK or EIN are marked EXACT.
