Item Classification
What's included
Complete business description, audited financial statements, risk factors, management bios, and how the company plans to spend IPO proceeds.
Filed weeks or months before the IPO; multiple amendments follow SEC review.
Market Dynamics
The review process
The SEC reviews the S-1 and sends comments. Companies respond with amendments (S-1/A) until the SEC is satisfied.
Track S-1 filings to discover upcoming IPOs and research companies before they go public.
Key Resources
IPO timing clues
Watch for the pricing amendment—when share price and deal size are added, the IPO is usually days away.
Companies file an S-1 before their initial public offering (IPO). The document goes through several rounds of SEC review and amendments before the stock starts trading.
Frequently Asked Questions
Can companies keep S-1 filings confidential?
Emerging growth companies may submit drafts confidentially, but the public S-1 must post at least 15 days before the roadshow.
What’s the difference between S-1 and S-3?
S-1 is the long-form registration for issuers without seasoned issuer status. S-3 is short-form and available only to companies meeting float and reporting history thresholds.
How old can S-1 financials be at pricing?
Financials generally go stale after 134/135 days for large accelerated or accelerated filers; others follow the 134/135-day convention as well.
When must a confidential S-1 become public?
At least 15 days before the roadshow (or 21 days before effectiveness if no roadshow) the draft must be filed publicly.
