Quest Diagnostics Share Buyback History
A share buyback, also called a stock repurchase, is when a company uses cash to buy its own shares. Quest Diagnostics 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.
Quest Diagnostics used $450.0M to repurchase common stock in fy 2025. Across the latest 5 reported fiscal years, total share repurchases were $4.48B. The latest reported quarter showed $300.0M of share repurchases.
| Fiscal year | Period ended | Share repurchases |
|---|---|---|
| 2025 | 2025-12-31 | $450.0M |
| 2024 | 2024-12-31 | $151.0M |
| 2023 | 2023-12-31 | $275.0M |
| 2022 | 2022-12-31 | $1.41B |
| 2021 | 2021-12-31 | $2.20B |
| 2020 | 2020-12-31 | $325.0M |
| 2019 | 2019-12-31 | $353.0M |
| 2018 | 2018-12-31 | $322.0M |
| 2017 | 2017-12-31 | $465.0M |
| 2016 | 2016-12-31 | $590.0M |
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.
