Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 226.3M ÷ 159.9M. 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.

-41.60%

Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-41.60%) + dividends paid over that year ($0) ÷ 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.

-41.60%

Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($-1.2B) ÷ today's market cap ($1.5B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.
