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.: 1.83%
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 —.: 1.82%
Dividend/share (fwd)The indicated annual dividend: the last regular payment × payments a year, for a company that pays the same amount each time.: $0.86
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 55.9M ÷ 56.1M. 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.: 0.40%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (0.40%) + dividends paid over that year ($47.2M) ÷ market_cap_at(2025-06-30) ($3.1B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 1.90%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($42.4M) ÷ today's market cap ($2.6B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 1.62%2016-09 0.3%2026-06 0.9%+178.6% over the window
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $42.4M + TTM dividends $47.2M) ÷ today's market cap ($2.6B). Same caveat as the cash buyback yield.: 3.42%2016-09 1.1%2026-06 1.9%+79.5% over the window
