How shares outstanding is measured

This ranking uses TTM weighted-average diluted shares — the share count companies report alongside their earnings filings, averaged over the four most recent fiscal quarters and adjusted to assume that all dilutive instruments (options, RSUs, convertibles) were exercised. It captures the size of the equity float, not its market value.

Share counts move with corporate actions: buybacks shrink them, secondary offerings and equity-based compensation expand them, and stock splits multiply them mechanically. Multiplied by the share price, this number becomes market capitalization. For per-share metrics see EPS explained. Non-U.S.-dollar filers are shown on comparable U.S. dollar amounts using the same filing translation rules as other statement leaderboards. Rankings USD translation methodology · IFRS IAS 21 (official) Note: ETFs, mutual funds and shell companies are excluded from the underlying dataset.
