Dilution occurs when new shares or securities convertible to shares are issued, reducing the ownership stake and per-share metrics of existing shareholders.
In corporate finance, dilution is a key consideration when evaluating capital-raising moves, stock compensation plans, or convertible securities. Analysts and investors look at indicators such as fully diluted shares (the total number of shares if all convertible securities are converted) and diluted earnings per share, which estimates per-share profitability after such conversions. These measures help compare performance and capital costs across different scenarios. Market pricing may reflect expectations of potential dilution, especially around planned financings or large option grants.
Dilution lowers the relative ownership and voting power of current holders. If net income does not grow proportionally with the new shares, earnings per share can fall. Companies disclose the sources and potential magnitude of dilution in filings and investor presentations, outlining stock options, warrants, convertible debt, or other instruments that could add to the share count.
After a planned equity financing, the number of outstanding shares increases, potentially diluting existing shareholders' ownership and reducing per-share earnings if net income does not rise correspondingly.
