What does the Number of outstanding shares mean?

The number of outstanding shares refers to the total shares of a company's stock that are currently held by shareholders, including institutional investors and company insiders, but excluding treasury shares. This figure is crucial for calculating key metrics like earnings per share (EPS) and market capitalization, as it reflects the equity ownership in the company. Changes in the number of outstanding shares can result from stock issuance, buybacks, or stock splits, impacting shareholder value and control.
