Buyback yield (realized, 1y)1 − shares_at(2026-09-30) ÷ shares_at(2025-09-30) = 1 − 70.5M ÷ 71.7M. 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.

1.76%

Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (1.76%) + dividends paid over that year ($0) ÷ market_cap_at(2025-09-30) ($9B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.

1.76%

Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($278.5M) ÷ today's market cap ($11.7B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.
