Rio Tinto Share Buyback History
A share buyback, also called a stock repurchase, is when a company uses cash to buy its own shares. Rio Tinto 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.
Rio Tinto used $0 to repurchase common stock in fy 2022. Across the latest 3 reported fiscal years, total share repurchases were $2.40B.
| Fiscal year | Period ended | Share repurchases |
|---|---|---|
| 2022 | 2022-12-31 | $0 |
| 2021 | 2021-12-31 | $0 |
| 2017 | 2017-12-31 | $2.40B |
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.
