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.
SEC-reported period-end shares
TickerStat displays period-end common shares from SEC filings and adjusts older values to the current share basis when SEC-reported stock-split conversion ratios are available. Values remain as reported when no split ratio is available. Fiscal periods can differ from calendar years, so exact period-end dates are included.
