What Is an IPO?
An initial public offering (IPO) refers to the process of offering shares of a private corporation to the public in a new stock issuance. Public share issuance allows a company to raise capital from public investors. The transition from a private to a public company can be an important time for private investors to fully realize gains from their investment as it typically includes share premiums for current private investors. Meanwhile, it also allows public investors to participate in the offering.


A company planning an IPO will typically select an underwriter or underwriters. They will also choose an exchange in which the shares will be issued and subsequently traded publicly.


The term initial public offering (IPO) has been a buzzword on Wall Street and among investors for decades. The Dutch are credited with conducting the first modern IPO by offering shares of the Dutch East India Company to the general public. Since then, IPOs have been used as a way for companies to raise capital from public investors through the issuance of public share ownership. Through the years, IPOs have been known for uptrends and downtrends in issuance. Individual sectors also experience uptrends and downtrends in issuance due to innovation and various other economic factors. Tech IPOs multiplied at the height of the dot-com boom as startups without revenues rushed to list themselves on the stock market. The 2008 financial crisis resulted in a year with the least number of IPOs. After the recession following the 2008 financial crisis, IPOs ground to a halt, and for some years after, new listings were rare. More recently, much of the IPO buzz has moved to a focus on so-called unicorns—startup companies that have reached private valuations of more than $1 billion.
Investors and the media heavily speculate on these companies and their decision to go public via an IPO or stay private.

How IPOs Work
Prior to an IPO, a company is considered private. As a private company, the business has grown with a relatively small number of shareholders including early investors like the founders, family, and friends along with professional investors such as venture capitalists or angel investors.

When a company reaches a stage in its growth process where it believes it is mature enough for the rigors of SEC regulations along with the benefits and responsibilities to public shareholders, it will begin to advertise its interest in going public. Typically, this stage of growth will occur when a company has reached a private valuation of approximately $1 billion, also known as unicorn status. However, private companies at various valuations with strong fundamentals and proven profitability potential can also qualify for an IPO, depending on the market competition and their ability to meet listing requirements.

An IPO is a big step for a company. It provides the company with access to raising a lot of money. This gives the company a greater ability to grow and expand. The increased transparency and share listing credibility can also be a factor in helping it obtain better terms when seeking borrowed funds as well.

IPO shares of a company are priced through underwriting due diligence. When a company goes public, the previously owned private share ownership converts to public ownership and the existing private shareholders’ shares become worth the public trading price. Share underwriting can also include special provisions for private to public share ownership. Generally, the transition from private to public is a key time for private investors to cash in and earn the returns they were expecting. Private shareholders may hold onto their shares in the public market or sell a portion or all of them for gains.

Meanwhile, the public market opens up a huge opportunity for millions of investors to buy shares in the company and contribute capital to a company’s shareholders' equity. The public consists of any individual or institutional investor who is interested in investing in the company. Overall, the number of shares the company sells and the price for which shares sell are the generating factors for the company’s new shareholders' equity value. Shareholders' equity still represents shares owned by investors when it is both private and public, but with an IPO the shareholders' equity increases significantly with cash from the primary issuance.
