FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: 2.11%2016-10 5.3%2026-08 1.2%-78.0% over the window
Buyback yield (realized, 1y)1 − shares_at(2026-08-01) ÷ shares_at(2025-08-02) = 1 − 141.8M ÷ 141.1M. Point-in-time share counts from the company's own SEC filings (the same count at both ends), published only when the cash flow statement shows repurchases inside that window. A falling price can't inflate it; negative means net dilution.: -0.54%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-0.54%) + dividends paid over that year ($0) ÷ market_cap_at(2025-08-02) ($12.5B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: -0.54%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($384.4M) ÷ today's market cap ($38.6B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 1.00%2016-10 -0.7%2026-08 0.6%-182.1% over the window
