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.
Dividend & buyback yield over time
Stacked annual yields — buyback yield (TTM cash repurchases ÷ market cap) plus dividend yield from the same fiscal-year-end key-metrics period — show how total cash return per dollar of equity has evolved.
Buybacks vs stock-based compensation
Annual cash repurchases set against stock-based compensation. Coverage above 1× means buybacks fully offset the equity dilution from SBC. TTM coverage: 0.00×.
Capital allocation mix
How Plug Power splits cash returned to shareholders between dividends and buybacks, plus the headroom on free cash flow that's still available for additional repurchases.
Buybacks vs dividends (share of cash returned)

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 Plug Power'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.
