FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: 3.22%2016-09 3.1%2026-09 3.8%+23.0% over the window
Buyback yield (realized, 1y)1 − shares_at(2026-09-30) ÷ shares_at(2025-09-30) = 1 − 402.3M ÷ 423.8M. 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.: 5.07%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (5.07%) + dividends paid over that year ($0) ÷ market_cap_at(2025-09-30) ($35.8B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 5.07%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($1.1B) ÷ today's market cap ($13.1B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 8.03%2016-09 0.0%2026-09 9.6%
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $1.1B + TTM dividends $0) ÷ today's market cap ($13.1B). Same caveat as the cash buyback yield.: 8.03%2016-09 0.0%2026-09 9.6%
