About the metric

What shares outstanding means

Shares outstanding is the number of common shares held by investors at a reporting-period end. The count can change because of stock issuance, repurchases, conversions, acquisitions, or stock splits.

Calculation and source

SEC-reported period-end shares

TickerStat displays period-end common shares from SEC filings and adjusts older values to the current share basis when a stock-split conversion ratio is reported directly or evidenced by a later filing’s restated historical share balance. After repeated reverse splits, an old period can represent less than one current-basis share; this is a split-adjusted equivalent, not a literal historical certificate count. Values remain as reported when no reliable split ratio is available. Fiscal periods can differ from calendar years, so exact period-end dates are included.
