Buyback yield (realized, 1y)1 − shares_at(2026-07-03) ÷ shares_at(2025-06-27) = 1 − 244.5M ÷ 243.3M. 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.

-0.48%

Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-0.48%) + dividends paid over that year ($0) ÷ market_cap_at(2025-06-27) ($5.7B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.

-0.48%

Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($0) ÷ today's market cap ($4.9B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.
