IPOs Explained: How Companies Go Public

An IPO, or initial public offering, is the process a private company goes through to sell shares to the public for the first time and become a publicly traded company. Once the IPO is complete, anyone with a brokerage account can buy and sell shares of that company on a stock exchange.

Before an IPO, a company is typically owned by its founders, early employees, and private investors like venture capital firms. Going public opens the door to a much bigger pool of investors and raises money the company can use to grow, pay off debt, or reward early backers.

Why Do Companies Go Public?

Companies choose to go public for a mix of financial and strategic reasons. The most common ones include:

• Raising capital: Selling shares to the public brings in a large amount of cash the company can use for expansion, research, or paying down debt.
• Providing liquidity: Founders, employees, and early investors often hold shares that are hard to sell while the company is private. An IPO gives them a way to eventually cash out.
• Increasing visibility and credibility: Being publicly traded can boost a company’s profile with customers, partners, and future employees.
• Using stock as currency: Public companies can more easily use their shares to acquire other businesses or offer competitive stock-based compensation.

Going public also comes with real trade-offs, like increased regulatory scrutiny, quarterly reporting requirements, and pressure from shareholders to deliver short-term results. Not every company wants that, which is why some businesses stay private for a long time, or indefinitely.

How Does the IPO Process Actually Work?

Taking a company public is a long, detailed process that usually takes several months to more than a year. Here’s a simplified walk-through of the major steps.

Step 1: Hiring Underwriters

The company hires one or more investment banks, known as underwriters, to manage the IPO. These banks help determine how many shares to sell, what price range makes sense, and how to market the offering to investors.

Step 2: Filing With Regulators

In the U.S., the company files a registration statement with the Securities and Exchange Commission (SEC), most commonly a document called an S-1. This filing discloses detailed information about the company’s business, finances, risks, and management team.

This is often the first time outside investors get a real, detailed look at the company’s financials, and it’s a useful document to read if you’re considering investing in a newly public company.

Step 3: The Roadshow

Company executives and underwriters travel (often virtually now) to pitch the company to large institutional investors, like mutual funds and pension funds. This is called a roadshow. Feedback from these meetings helps the underwriters gauge demand and set a final price.

Step 4: Pricing the IPO

The night before trading begins, the company and underwriters set the final IPO price based on investor demand gathered during the roadshow. This is the price at which shares are first sold to institutional investors and some qualified individual investors, before the stock starts trading publicly.

Step 5: The Stock Starts Trading

On the first trading day, the stock lists on an exchange like the NYSE or NASDAQ under its ticker symbol, and the general public can start buying and selling shares. The opening trade price can differ significantly from the IPO price, depending on demand.

What Happens to the Stock Price After an IPO?

IPO stock prices can be volatile in the early days and months of trading. Some IPOs “pop,” meaning the stock jumps well above its IPO price on the first day, while others trade flat or even fall below their offering price.

A few things to keep in mind if you’re considering buying shares around an IPO:

1. Most everyday investors cannot buy shares at the actual IPO price. That price is typically reserved for institutional investors and select clients of the underwriting banks.
2. Early price swings often reflect hype and limited share supply rather than the company’s long-term fundamentals.
3. Many IPO shares have a lock-up period, usually 90 to 180 days, during which insiders and early investors cannot sell their shares. When the lock-up expires, a wave of selling can sometimes push the price down.
4. A company’s long-term performance depends on its actual business results, not just IPO-day excitement.

Are IPOs a Good Investment for Beginners?

IPOs can be exciting, but they also carry real risk, especially in the short term. Newly public companies often have less financial history available, and stock prices can swing sharply in the first weeks and months of trading.

In practice, many financial professionals suggest that beginner investors research a newly public company just as carefully (or more carefully) as an established one before buying, rather than getting caught up in IPO-day hype. Reading the company’s SEC filings, understanding its business model, and considering how it fits your overall goals matters more than trying to catch a first-day pop.

What’s the Difference Between an IPO and a Direct Listing?

A traditional IPO involves underwriters helping the company sell newly issued shares to raise capital. A direct listing, by contrast, allows a company to list its existing shares directly on an exchange without issuing new shares or using underwriters to sell them in advance. Some companies choose direct listings to avoid certain IPO costs and lock-up restrictions, though this approach isn’t right for every business.

Key Takeaways

• An IPO is the process a private company uses to sell shares to the public for the first time and become publicly traded.
• Companies go public mainly to raise money, offer liquidity to early investors, and boost visibility.
• The IPO process includes hiring underwriters, filing with regulators, a roadshow, pricing, and finally listing on an exchange.
• Most everyday investors cannot buy shares at the official IPO price. They typically buy once trading opens to the public.
• IPO stocks can be volatile, and it’s worth researching the company’s fundamentals rather than chasing first-day hype.

Frequently Asked Questions

Can beginner investors buy shares during an IPO?
Usually not at the actual IPO price, since that’s typically reserved for institutional investors and select clients of the underwriting banks. Most individual investors buy shares once the stock starts trading publicly on the exchange.

What is an IPO lock-up period?
It’s a set window, often 90 to 180 days, after the IPO during which company insiders and early investors are restricted from selling their shares. This is meant to prevent a flood of shares from hitting the market right away.

Why do some IPO stocks drop after their first day of trading?
Prices can fall if early enthusiasm fades, if the stock was priced too high relative to investor demand, or if the company’s next earnings reports don’t meet expectations. Short-term price moves don’t always reflect long-term business performance.

What is the difference between an IPO price and the opening trading price?
The IPO price is what institutional and select investors pay before public trading begins. The opening trading price is set once the stock starts trading on the exchange and can be higher or lower, depending on demand.

Do all companies that go public stay public forever?
No. Some public companies are later acquired, merge with another business, or go private again through a process where a group of investors buys back all outstanding shares.
