Mastec Share Buyback History
A share buyback, also called a stock repurchase, is when a company uses cash to buy its own shares. Mastec 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.
Mastec used $77.3M to repurchase common stock in fy 2025. Across the latest 5 reported fiscal years, total share repurchases were $158.6M. The latest reported quarter showed $0 of share repurchases.

| 2024 | 2024-12-31 | $0 |
| 2023 | 2023-12-31 | $0 |

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.
