An initial public offering (IPO) is the first time a private company sells shares of stock to the general public. The company transitions from private ownership, where shares are held by founders, employees, and investors, to public trading on a stock exchange like the NYSE or Nasdaq. For SaaS and cloud companies, an IPO often marks the shift from growth-stage startup to scaled enterprise. This guide walks through the IPO process step by step, from filing the S-1 registration statement to the first day of trading, and covers what changes for marketing teams once a company goes public.
What is an Initial Public Offering
An initial public offering (IPO) is the first time a private company sells shares of stock to the general public. Before an IPO, ownership is limited to founders, employees, and private investors. After the IPO, anyone can buy shares on a public stock exchange like the New York Stock Exchange or Nasdaq. The process involves hiring investment banks, filing registration documents with the Securities and Exchange Commission (SEC), marketing shares to institutional investors, and setting a final price. Once trading begins, the company is publicly traded.
Why Companies Pursue an IPO
Capital is usually the primary driver. An IPO generates funds for expansion, research and development, acquisitions, or paying down debt. Unlike debt financing, equity does not require repayment. Early investors, founders, and employees also gain liquidity. After a lockup period ends, they can sell shares or diversify their holdings. For many venture-backed companies, the IPO is the exit event that returns capital to investors.
- Brand visibility: Public company status often builds credibility with customers, partners, and potential hires.
- Acquisition currency: Publicly traded stock can be used to acquire other companies without spending cash.
- Equity compensation: Public shares make stock-based compensation more attractive to employees.
Requirements to Go Public
Before filing for an IPO, a company has to meet eligibility requirements set by the SEC and the stock exchange where it plans to list. The SEC requires audited financial statements, typically covering three years, prepared according to Generally Accepted Accounting Principles (GAAP). The company also has to demonstrate adequate internal controls over financial reporting. Stock exchanges have their own listing standards. The NYSE and Nasdaq each set minimum thresholds for market capitalization, share price, number of shareholders, and corporate governance. Meeting all of the requirements often takes months of preparation, which is why many companies begin working with auditors and legal counsel well before they formally start the IPO process.
The IPO Process from Filing to Trading
The IPO process typically takes several months and follows a predictable sequence. Each step builds on the previous one.
1) Select investment bank underwriters
The company chooses one or more investment banks to manage the offering. The lead underwriter, sometimes called the bookrunner, coordinates the process. Other banks may join as part of a syndicate to help distribute shares. Underwriters advise on timing, valuation, and deal structure. They also handle regulatory filings and market the shares to investors.
2) File the S-1 registration statement with the SEC
The S-1 is the formal registration document filed with the SEC. It includes the prospectus, which discloses the company’s business model, financials, risk factors, management team, and intended use of proceeds. The prospectus is the primary document investors use to evaluate the offering. It has to be accurate and complete because the company and its executives can face legal liability for material misstatements.
3) Complete SEC review and respond to comments
After the S-1 is filed, the SEC reviews it and issues comment letters. Comment letters request clarification, additional disclosure, or revisions to specific sections. The company and its legal counsel respond in writing, often filing amended versions of the S-1. The back-and-forth continues until the SEC declares the registration “effective,” which clears the company to proceed with the offering.
4) Conduct the investor roadshow
The roadshow is a marketing tour where company executives present to institutional investors. The goal is to build interest and gauge demand for the shares. Roadshows typically include in-person meetings in major financial centers and virtual presentations. Management presents the company’s growth story, competitive position, and financial outlook. Investors ask questions and indicate how many shares they might want to buy and at what price.
5) Price the offering and allocate shares
After the roadshow, underwriters set the final IPO price based on investor demand. The process of collecting indications of interest is called book building. The price is typically set the night before trading begins. Shares are allocated primarily to institutional investors, though some brokerages offer limited IPO access to retail customers.
6) List and begin trading on the exchange
On the IPO date, shares begin trading on the NYSE or Nasdaq. The opening price, determined by supply and demand in the market, often differs from the IPO price. First-day trading can be volatile as buyers and sellers establish the market price. A strong first-day “pop” is often seen as a sign of investor enthusiasm, though it also means the company left money on the table by pricing too low.
Key Parties Involved in an IPO
Several parties play distinct roles throughout the IPO process.
Lead underwriters and the syndicate
The lead underwriter coordinates the offering, advises on pricing, and takes responsibility for selling the shares. The syndicate consists of other investment banks that help distribute shares to their investor clients.
The SEC and regulatory reviewers
The SEC reviews registration documents to ensure adequate disclosure. Its role is to protect investors by requiring transparency, not to evaluate whether the company is a good investment.
Stock exchanges including NYSE and Nasdaq
Exchanges set listing standards and provide the marketplace where shares trade after the IPO. They also enforce ongoing compliance with listing requirements.
Auditors and legal counsel
Auditors certify the company’s financial statements. Legal counsel prepares filings, ensures regulatory compliance, and advises on disclosure obligations.
Institutional and retail investors
Institutional investors (mutual funds, pension funds, hedge funds) are the primary buyers at IPO. Retail investors typically buy shares after trading begins on the open market.
What Happens after the IPO
Going public is the beginning of a new phase, not the end of a process.
- Quarterly and annual reporting: Public companies file 10-Q (quarterly) and 10-K (annual) reports with the SEC, disclosing financial results and material developments.
- Lockup period: Insiders, including executives and early investors, are typically restricted from selling shares for 90 to 180 days after the IPO.
- Analyst coverage: Research analysts at investment banks begin publishing reports on the company, which can influence the stock price.
- Ongoing compliance: Companies have to meet exchange listing standards, maintain proper governance, and comply with regulations like Sarbanes-Oxley.
IPO Alternatives Including Direct Listings and SPACs
Direct listing
In a direct listing, a company lists existing shares on an exchange without issuing new stock or using underwriters to set the price. No capital is raised, but existing shareholders gain liquidity. Spotify and Slack both used direct listings.
SPAC merger
A SPAC (special purpose acquisition company) is a publicly traded shell company that merges with a private company to take it public. The private company becomes public through the merger rather than a traditional IPO.
Staying private with secondary offerings
Some companies choose to remain private longer by allowing early investors and employees to sell shares in private secondary transactions. Private secondary sales provide liquidity without the obligations of public company status.
How an IPO Reshapes Marketing and Brand Strategy
Quiet period restrictions on communications
The quiet period runs from the S-1 filing until after the IPO. During the quiet period, the company cannot make promotional statements that could be seen as conditioning the market. Marketing and PR activities are constrained, and any public communications require legal review.
Analyst and investor relations
A new investor relations function becomes necessary. Marketing has to coordinate messaging with IR to ensure consistency. Earnings calls, investor presentations, and analyst days become regular activities that require marketing support.
Brand reputation and public scrutiny
Public companies face greater media attention. Stock price movements, executive compensation, and strategic decisions all become public information. Marketing plays a role in communicating company performance and managing reputation with a broader audience.
Frequently Asked Questions About Initial Public Offerings
The IPO process typically takes four to six months from selecting underwriters to the first day of trading. The timeline varies based on SEC review cycles, market conditions, and how prepared the company is when it begins.
Going public makes sense when a company has the infrastructure to handle public company obligations and a clear use for the capital. Premature IPOs can distract management and burden the company with compliance costs before it is ready.
An IPO involves issuing new shares and raising capital with underwriter support. A direct listing allows existing shareholders to sell shares on an exchange without raising new funds or setting a predetermined price.
Retail investors rarely receive shares at the IPO price because allocations go primarily to institutional investors. Some brokerages offer limited IPO access to eligible customers, but most retail investors buy shares after trading begins.
The lockup period is an agreement that prevents insiders from selling their shares for a set period after the IPO, typically 90 to 180 days. The lockup prevents immediate selling pressure on the stock.
