Stock dilution, also known as equity dilution, is the decrease in existing shareholders' ownership percentage of a company as a result of the company issuing new equity. New equity increases the total shares outstanding which has a dilutive effect on the ownership percentage of existing shareholders. This increase in the number of shares outstanding can result from a primary market offering (including an initial public offering), employees exercising stock options, or by issuance or conversion of convertible bonds, preferred shares or warrants into stock. This dilution can shift fundamental positions of the stock such as ownership percentage, voting control, earnings per share, and the value of individual shares.
