Buyback yield (realized, 1y)1 − shares_at(2025-12-31) ÷ shares_at(2024-12-31) = 1 − 76.6M ÷ 80.8M. 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.

5.19%

Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (5.19%) + dividends paid over that year ($0) ÷ market_cap_at(2024-12-31) ($16.9B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.

5.19%

Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($750M) ÷ today's market cap ($12.4B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.
