Valuation

P/E (ttm)Price ÷ TTM diluted EPS. Net income carries everything below the operating line, including one-off gains. Negative when the trailing year lost money.: 19.3×2016-09 22.112026-09 19.66-11.1% over the window
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.: 15.2×2016-09 11.782026-09 15.15+28.6% over the window

FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: -7.33%2016-06 -4.7%2026-06 -6.9%+47.3% 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.: 2.37%
Dividend/share (fwd): $3.87
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 169.0M ÷ 160.5M. 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.: -5.28%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-5.28%) + dividends paid over that year ($632.1M) ÷ market_cap_at(2025-06-30) ($24.7B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: -2.72%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($-1.1B) ÷ today's market cap ($27.6B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: -3.89%2016-06 -1.3%2026-06 -3.6%+186.3% over the window
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $-1.1B + TTM dividends $632.1M) ÷ today's market cap ($27.6B). Same caveat as the cash buyback yield.: -1.59%2016-06 1.0%2026-06 -1.5%-254.3% over the window
