FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: 2.57%2016-12 5.7%2026-06 2.1%-63.6% over the window
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 108.5M ÷ 107.6M. 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.: -0.81%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-0.81%) + dividends paid over that year ($0) ÷ market_cap_at(2025-06-30) ($6.9B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: -0.81%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($4.3M) ÷ today's market cap ($11.6B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 0.04%2016-09 6.6%2026-06 0.0%-99.6% over the window
