When an unlisted company makes either a fresh issue of securities or an offer for sale of its existing securities or both for the first time to the public. This paves way for listing and trading of the issuer’s securities.
An Initial Public Offering (IPO) is the first sale of stock by a private company to the public. IPOs are often issued by smaller, younger companies seeking capital to expand, but can also be done by large privately-owned companies looking to become publicly traded.
In an IPO, the issuer may obtain the assistance of an underwriting firm, which helps it determine what type of security to issue (common or preferred), best offering price and time to bring it to market.
Also referred to as a "public offering".
IPOs can be a risky investment. For the individual investor, it is tough to predict what the stock will do on its initial day of trading and in the near future since there is often little historical data with which to analyze the company. Also, most IPOs are of companies going through a transitory growth period, and they are therefore subject to additional uncertainty regarding their future value.
Reasons for listing
When a company lists its shares on a public exchange, it will almost invariably look to issue additional new shares in order to raise extra capital at the same time. The money paid by investors for the newly-issued shares goes directly to the company (in contrast to a later trade of shares on the exchange, where the money passes between investors). An IPO, therefore, allows a company to tap a wide pool of stock market investors to provide it with large volumes of capital for future growth. The company is never required to repay the capital, but instead the new shareholders have a right to future profits distributed by the company.
The existing shareholders will see their shareholdings diluted as a proportion of the company's shares. However, they hope that the capital investment will make their shareholdings more valuable in absolute terms.
In addition, once a company is listed, it will be able to issue further shares via a rights issue, thereby again providing itself with capital for expansion without incurring any debt. This regular ability to raise large amounts of capital from the general market, rather than having to seek and negotiate with individual investors, is a key incentive for many companies seeking to list.
