Secondary Offerings: A secondary offering is the sale of new or closely held shares by a company that has already made an initial public offering (IPO). There are two types of secondary offerings. A non-dilutive secondary offering is a sale of securities in which one or more major stockholders in a company sell all or a large portion of their holdings. The proceeds from this sale are paid to the stockholders that sell their shares. Meanwhile, a dilutive secondary offering involves creating new shares and offering them for public sale.
