A list of public companies' filings

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

To file for an IPO, a company must file a registration form called an S-1 or prospectus with the US Securities and Exchange Commission. S-1s detail a company's current business model, competitive landscape, and other financial information.

An initial public offering or 'IPO' is the process of a private company becoming public by putting shares of the company on the stock market for purchase.

An initial public offering is how a private company becomes public

This milestone requires plenty of preparation, starting with the SEC's S-1 registration, revealing key details about the company's finances and strategy. Investment bankers set valuations, secure long-term investors, and finalize share pricing before the public launch. IPOs provide companies with significant capital, but also demand transparency and invite public scrutiny.

The number of publicly traded companies has decreased in recent years

In 1996, more than 7,300 companies traded publicly on US stock markets, but that number has recently dropped to 4,300.

Second, the IPO process is expensive and time-consuming.

Chapter 7 and Chapter 11 filings can impact common stockholders

Publicly traded companies don’t file for bankruptcy out of nowhere—there are typically warning signs in a stock’s performance, quarterly earnings calls, and US Securities and Exchange Commission filings.

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.
