Kosmos Energy Share Buyback History
A share buyback, also called a stock repurchase, is when a company uses cash to buy its own shares. Kosmos Energy 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.
Kosmos Energy used $206.1M to repurchase common stock in fy 2018. Across the latest 5 reported fiscal years, total share repurchases were $239.4M. The latest reported quarter showed $78,000 of share repurchases.
| Fiscal year | Period ended | Share repurchases |
|---|---|---|
| 2018 | 2018-12-31 | $206.1M |
| 2017 | 2017-12-31 | $2.2M |
| 2016 | 2016-12-31 | $2.0M |
| 2015 | 2015-12-31 | $18.1M |
| 2014 | 2014-12-31 | $11.1M |
| 2013 | 2013-12-31 | $13.1M |
| 2012 | 2012-12-31 | $8.4M |
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.
