What Going Public Involves: An IPO Explained at a High Level
An initial public offering turns a private company into one whose shares trade on a stock exchange. Here is the general process, the main players and the lasting obligations.
When a company goes public, its shares become available for anyone to buy on a stock exchange. The most familiar route is an initial public offering, or IPO. For a company, it can mean access to capital and a liquid market for its stock. It also means a permanent change in how the company operates. This is a general explainer for curious readers, not investment or legal advice.
Why companies go public
- Raising capital. Selling shares to the public can raise money for growth, research or paying down debt.
- Liquidity. Founders, employees and early investors gain a market where they can eventually sell their shares.
- Currency for deals. Publicly traded stock can be used to acquire other companies or attract talent.
- Visibility. Public status can raise a company’s profile with customers and partners.
The main steps
The traditional IPO process takes many months of preparation. While details vary, it generally includes:
- Getting ready. Strengthening financial reporting, audits, internal controls and governance, often well before any filing.
- Choosing underwriters. Investment banks that help price the offering, market it and sell the shares.
- Filing a registration statement. In the United States, this is filed with the Securities and Exchange Commission and includes a detailed prospectus describing the business, risks and financials.
- SEC review. The SEC staff reviews the filing and may comment, leading to revisions.
- The roadshow. Management presents to potential institutional investors to gauge demand.
- Pricing and listing. The final price is set, shares are allocated and trading begins on an exchange.
There are also alternative paths to public markets, such as direct listings and mergers with special purpose acquisition companies, each with its own trade-offs.
Life after the IPO
The day shares start trading is the beginning, not the end. Public companies take on ongoing obligations, including:
- Regular public financial reports, such as annual and quarterly filings.
- Prompt disclosure of significant events.
- Stock exchange governance requirements, including independent directors and board committees.
- Rules about insider trading and how information is shared with investors.
Insiders are often subject to a lock-up period after the IPO during which they agree not to sell their shares.
The trade-offs
Going public brings scrutiny. Results are reported publicly every quarter, the stock price reacts to news, and the costs of compliance, audits and investor relations are substantial. Some companies decide to stay private longer, raising money from private investors instead. Others conclude that the benefits outweigh the burdens. The right answer depends on the company’s size, capital needs and appetite for public attention.
