Dividend yield (fwd)Indicated forward annual dividend ÷ current price — the rate the company has announced, not what was actually paid over the past year.

Dividend/share (fwd)

$3.36

Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 2.47B ÷ 2.50B. 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.

1.23%

Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (1.23%) + dividends paid over that year ($8.3B) ÷ market_cap_at(2025-06-30) ($197.7B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.

5.42%

Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($4.2B) ÷ today's market cap ($355.1B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.
