An initial public offering is how a private company becomes public.

Ride along on one coffee company's journey through the stock market to better understand how a company goes from private to public.

Initial public offering (IPO) is the term for when a company goes public

When a company completes its IPO, it's no longer a privately owned organization. Anyone can invest in the company by buying its shares on the stock market—opening up ownership of the business to the general public.

Companies go public via an initial public offering (IPO) to raise large amounts of capital, helping them expand, invest in new ventures, hire more staff, or pay off debts.

It's difficult for individual investors to purchase IPO shares

Although the process of going public means the general public can invest in a company, the initial investment period is different. Before individual investors get in on the action, investment bankers sell the shares to larger financial institutions who can afford the asking price and risk associated with an IPO.

Going public has pros and cons for a company.

An organization transfers ownership over to new shareholders—who could be anyone—following its IPO date. However, going public expands a company's ability to increase funding and grow its business. This guide dives into the advantages and disadvantages of going public, and what those pros and cons can mean for investors.

An S-1 reveals financial and other details to the public, often for the first time, when filing for an IPO

Many investment bankers work on IPOs

When a company undertakes an IPO, investment banks often buy many of the organization’s shares directly from the company, in order to sell the shares on the stock market. The bank stands to profit after marking up the shares.

Companies pay multiple fees as part of the IPO process

When a company decides to approach IPO, it typically hires investment bankers—who earn about 7% of the IPO’s gross proceeds—to help set the organization’s target valuation range and schedule an IPO date. But that isn't the only fee associated with the IPO process.

The cryptocurrency equivalent of going public

An initial coin offering (ICO) is cryptocurrency's version of an initial public offering (IPO).

If you're entering the field, get the details on how it all works.

Learn how to read a prospectus, the juicy document that any company must file with the SEC before going public

A prospectus typically contains information about the company's operations, including details about its management team and their compensation, financial statements, how it intends to use any capital raised by the IPO, and more. While these documents can be dense and lengthy, experts say that some of the most important sections of a prospectus for investors to look at include the risk factors section and the use of proceeds section.

IPOs that failed

Plenty of private companies fail once they try to go public. Failing can mean shares sell for less than their initial asking price on its IPO date, or it can look like a company pulling out of the IPO process at the last minute. Some companies with failed IPOs include Pets.com, Etsy, and Robinhood. Learn more about these companies and others here.
