Dividend yield (fwd)Indicated forward annual dividend ÷ current price — the rate the company has announced, not what was actually paid over the past year.: 0.58%
Dividend/share (fwd): $7.12
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 49.1M ÷ 47.9M. 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.: -2.61%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-2.61%) + dividends paid over that year ($329.2M) ÷ market_cap_at(2025-06-30) ($35B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: -1.67%
