Dividend yield (fwd)Indicated annual dividend ÷ last close: the last regular payment × payments a year, from our own dividend record. Shown only for a company that pays the same amount each time (raises and cuts allowed), whose payments are on schedule and agree with the dividends it reports paying; a company whose payments vary in size, such as an unequal interim and final, has no forward figure — see the ttm yield.

3.89%

Dividend yield (ttm)Dividends paid over the last year ÷ last close: the last full cycle of regular payments in our own dividend record. Below the forward yield after a raise, above it after a cut. Shown only when the record holds that full cycle and it agrees with the dividends the company reports paying; otherwise —.

3.85%

Dividend/share (fwd)The indicated annual dividend: the last regular payment × payments a year, for a company that pays the same amount each time.

Buyback yield (realized, 1y)1 − shares_at(2026-09-30) ÷ shares_at(2025-09-30) = 1 − 463.8M ÷ 468.1M. 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.

0.94%

Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (0.94%) + dividends paid over that year ($3.3B) ÷ market_cap_at(2025-09-30) ($90B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.

4.55%

Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($867.6M) ÷ today's market cap ($85.3B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.
