What it means
Before a company can offer shares to the public in the United States, the securities must be registered under the Securities Act of 1933, unless an exemption applies. Form S-1 is the general-purpose registration form, which means that it is available when a shorter form is not.
For most IPOs by US companies, it is the starting point. The prospectus section is the heart of the document.
It describes the business, industry, strategy, management, executive pay, major shareholders, use of proceeds and risk factors. It also includes audited financial statements and the management discussion and analysis (a narrative that explains the numbers).
The process is lengthy. The company works with lawyers, auditors and investment banks to draft the document, then files it with the SEC.
The staff reviews it and sends comments, the company responds with amendments, and the process repeats until the staff has no further comments and the registration becomes effective. Many companies can submit a draft registration statement for confidential review.
This lets them receive comments privately before filing publicly, and it helps them avoid revealing sensitive information if they decide not to proceed. The public filing must be made well before the roadshow starts.
The price and number of shares are usually left blank in the early versions. After the roadshow, the bankers set the price, and the final prospectus is filed under Rule 424(b), commonly as Form 424B4.
The company then receives the net proceeds after fees. For managers and investors, Form S-1 is a rare, complete view of a private company becoming public.
Reading the risk factors, the capitalisation table and the section on related party deals reveals the strengths and weaknesses of the business. Smart readers also look at how the company defines its key metrics.
In practice
Real-world examples.
Example
A fast-growing software company prepares for an IPO. It files a Form S-1 with three years of audited accounts and a long list of risk factors. The chief financial officer leads the work on the financial sections. The audit committee reviews each draft before it is filed.
Example
An existing shareholder wants to sell part of her stake after the company lists. The company files a Form S-1 that registers those shares for resale. The filing explains who is selling and how many shares are involved. The company does not receive any money from those sales.
Example
A retail investor reads the S-1 of a company she admires. She studies the section on use of proceeds and the table of existing shareholders before deciding whether to apply for shares. She also checks the lock-up terms that limit insider sales.
Formula
Calculation
Net proceeds = Shares sold x Offering price - Underwriting discount - Other offering costs
Worked example: A company sells 4,000,000 new shares at $25 per share, pays an underwriting discount of 6% and has other offering costs of $2,000,000.
Gross proceeds = 4,000,000 x $25 = $100,000,000
Underwriting discount = $100,000,000 x 6% = $6,000,000
Net proceeds = $100,000,000 - $6,000,000 - $2,000,000 = $92,000,000Case study
Seen in the real world.
Tidewater Robotics is a fictional private company used as an illustrative example. It wants to raise $100,000,000 to build a new factory and decides to go public.
The company hires underwriters and prepares a Form S-1 with its legal team. The SEC staff reviews it and raises several questions about revenue recognition, and the finance team provides detailed explanations. After several amendments, the registration becomes effective and the shares are priced.
The IPO raises the planned amount, less fees and costs. The case shows that an S-1 is not just paperwork, because the work forces a company to organise its numbers and tell its story clearly. Several managers say that the process was the best financial health check the company has had. It also shows that going public is the start of a long period of public reporting.
Watch out
Common mistakes.
- Treating the S-1 as a marketing brochure. It is a legal document, and misleading statements can create liability. Directors and officers who sign it are personally exposed.
- Underestimating the time and cost. Audits, legal work and SEC review typically take many months. Companies should plan well ahead of the date they want to list.
- Ignoring the risk factors. They often reveal the issues that matter most to the business. Reading them first is a fast way to understand the company.
Questions
People also ask.
Who files Form S-1?
A company that wants to register securities for sale to the public and does not qualify for a shorter form.
Is an S-1 only for IPOs?
No, it can also register resales by existing holders and other offerings, although IPOs are the best-known use. Debt, warrants and other securities may also be registered this way.
What happens after it is effective?
The company can sell the securities, and it takes on continuing reporting duties. Annual, quarterly and current reports follow.
