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.Div yieldIndicated annual dividend ÷ last close: the last regular payment × payments a year, from our own dividend record.

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.

Buyback yield (realized, 1y)1 − shares_at(2026-09-30) ÷ shares_at(2025-09-30) = 1 − 35.0M ÷ 35.3M. 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.: 0.81%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (0.81%) + dividends paid over that year ($105.5M) ÷ market_cap_at(2025-09-30) ($29.1B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 1.17%
