Dividend yield (fwd)Indicated annual dividend ÷ last close: the last regular payment × payments a year, from our own dividend record, not what was actually paid over the past year. Shown only when the record holds a full payment cycle that agrees with the dividends the company reports paying; otherwise —.

0.36%

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 where the forward yield is; otherwise —.

0.35%

Dividend/share (fwd)The indicated annual dividend: the last regular payment × payments a year.

Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 67.6M ÷ 67.2M. 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.

-0.68%

Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-0.68%) + dividends paid over that year ($63M) ÷ market_cap_at(2025-06-30) ($6.7B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.

0.26%

Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($0) ÷ today's market cap ($18.9B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.
