FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: 1.88%2016-09 -2.3%2026-06 1.1%-148.2% over the window
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 30.9M ÷ 31.4M. 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.: 1.71%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (1.71%) + dividends paid over that year ($0) ÷ market_cap_at(2025-06-30) ($2.2B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 1.71%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($57.8M) ÷ today's market cap ($3.5B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 1.66%2016-09 0.0%2026-06 1.0%
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $57.8M + TTM dividends $0) ÷ today's market cap ($3.5B). Same caveat as the cash buyback yield.: 1.66%2016-09 0.0%2026-06 1.0%
