Dividend yield (fwd)Indicated forward annual dividend ÷ current price — the rate the company has announced, not what was actually paid over the past year.: 1.01%
Dividend/share (fwd): $3.05
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 212.1M ÷ 215.6M. 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.: 1.62%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (1.62%) + dividends paid over that year ($658M) ÷ market_cap_at(2025-06-30) ($76.9B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 2.48%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($1.5B) ÷ today's market cap ($64.2B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 2.39%2016-06 5.9%2026-06 2.2%-63.1% over the window
