Initial public offering

society Maturity 11-13 Next article →

An Initial Public Offering is often called an IPO. It is also known as a stock launch. This happens when a private company decides to become a public company. The company sells small pieces of itself called shares to many people. These people can be large groups called institutional investors. They can also be regular people called retail investors.

This process is sometimes called "going public." It is a big step for any business. Companies do this to raise new money to help them grow. It also lets the original owners sell their parts for money. Once the IPO is finished, the shares trade freely on a stock exchange.

Preparing for an IPO is a very big job. A company must plan carefully to be successful. They often work with special banks called underwriters. These banks act as helpers for the company. One bank might be the "lead underwriter" or the "bookrunner." This bank does the most work to help sell the shares. They also help decide what the price of a share should be.

Underwriters earn a fee for their help. This fee is called an underwriting spread. A large group of banks working together is called a syndicate. This helps the company reach many different investors.

There are many rules that companies must follow during an IPO. In the United States, a group called the Securities and Exchange Commission watches over them. In the United Kingdom, the UK Listing Authority does this job. Companies must share a lot of information with the public. They do this by writing a long document called a prospectus.

Sometimes, a preliminary version is called a "red herring." It has a red warning on the front cover. This warning says the information might still change. This helps keep everything fair and honest for the people buying shares.

Selling shares can happen in different ways. One way is the "fixed price method." This is when the company and its banks pick one price. Another way is called "book building." This uses data to see how many people want to buy.

Sometimes, the price is set lower than it could be. This is called underpricing. It can cause the share price to jump up very fast. People call this an "IPO pop." For example, a company called theglobe.com had a famous IPO in 1998. Its shares were priced at $9. On the first day, the price jumped 1,000% to $97.

This way of sharing ownership is a very old idea. Some scholars believe the Roman Republic used it long ago. A group called the publicani sold shares to investors. These people traded their parts in a market near the Forum.

In the United States, the Bank of North America had the first IPO around 1783. Before the year 1860, many U.S. companies sold shares directly to the public. They did not use banks to help them back then. Today, the process is much more complex and involves many lawyers and banks. It remains a main way for businesses to join the global market.
