FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: 3.71%2016-09 4.1%2026-06 3.1%-23.6% over the window
Dividend yield (fwd)Indicated forward annual dividend ÷ current price — the rate the company has announced, not what was actually paid over the past year.: 0.16%
Dividend/share (fwd): $2.60
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 35.2M ÷ 35.3M. 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.: 0.25%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (0.25%) + dividends paid over that year ($91.6M) ÷ market_cap_at(2025-06-30) ($18.9B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 0.73%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($112.9M) ÷ today's market cap ($58.2B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 0.19%2016-09 1.2%2026-06 0.2%-86.0% over the window
