Fastly Share Buyback History

A share buyback, also called a stock repurchase, is when a company uses cash to buy its own shares. Fastly share buyback history shows the reported cash used for repurchases. Buybacks can reduce shares outstanding, but issuance, stock-based compensation, acquisitions, and stock splits can change the share count separately.

Fastly used $10.7M to repurchase common stock in fy 2022. Across the latest 2 reported fiscal years, total share repurchases were $10.7M.

TickerStat uses SEC-reported cash payments for common-stock repurchases. The amounts describe capital returned through buybacks; they are not a forecast or a measure of the number of shares retired.

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.
