Valuation

P/OI (ttm)Price ÷ TTM operating income. Excludes the below-the-line items that make P/E jump — mark-to-market gains, settlements, tax true-ups.: 24.2×2016-09 20.372026-09 24.17+18.7% over the window

FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: -1.43%2016-06 2.6%2026-06 -1.3%-150.6% over the window
Dividend yield (fwd)Indicated forward annual dividend ÷ current price — the rate the company has announced, not what was actually paid over the past year.: 2.93%
Dividend/share (fwd): $3.38
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 297.7M ÷ 295.3M. 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.: -0.80%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-0.80%) + dividends paid over that year ($996.9M) ÷ market_cap_at(2025-06-30) ($30.3B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 2.49%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($0) ÷ today's market cap ($34.3B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 0.00%2016-06 0.0%2026-06 0.0%
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $0 + TTM dividends $996.9M) ÷ today's market cap ($34.3B). Same caveat as the cash buyback yield.: 2.91%2016-06 4.4%2026-06 2.6%-40.1% over the window
