Share count history
Diluted weighted-average shares drive the EPS denominator and per-share capital-return maths. A falling diluted share count means buybacks are outpacing dilution from stock-based compensation and option exercises.
Diluted vs basic shares (annual)
Year-over-year change in diluted shares
Green is fewer shares vs the prior fiscal year (net repurchase); red is growth (dilution). The earliest year shown has no prior year to compare.

Data & methodology
Where do buyback, dividend and compensation figures come from?
Cash buyback spend (common stock repurchased), dividends paid and stock-based compensation come from Phillips 66's consolidated cash flow statements — quarterly 10-Q and annual 10-K SEC filings, in USD as reported.
How are diluted shares and yields calculated?
Diluted weighted-average share counts come from the income statement (EPS denominator). Trailing twelve-month (TTM) aggregates sum the four most recent reported quarters. Buyback and dividend yields divide TTM cash flows by market capitalisation at the latest quarter-end.
How is buyback capacity defined?
Capacity compares TTM repurchases to free cash flow after dividends: operating cash flow minus capital expenditure, minus dividends paid, versus actual buybacks over the same trailing window.
Is this investment advice?
No. Figures are for informational and educational use only. Past buybacks and dividends do not predict future returns.
