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.: 20.3×2016-12 22.022026-10 20.65-6.2% 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.: 15.9×2016-12 11.732026-10 15.92+35.7% over the window

FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: -6.98%2016-09 -3.8%2026-06 -6.9%+81.6% over the window
Dividend yield (fwd)Indicated annual dividend ÷ last close: the last regular payment × payments a year, from our own dividend record. Shown only for a company that pays the same amount each time (raises and cuts allowed), whose payments are on schedule and agree with the dividends it reports paying; a company whose payments vary in size, such as an unequal interim and final, has no forward figure — see the ttm yield.: 2.33%
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 when the record holds that full cycle and it agrees with the dividends the company reports paying; otherwise —.: 2.33%
Dividend/share (fwd)The indicated annual dividend: the last regular payment × payments a year, for a company that pays the same amount each time.: $4.00
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 ($29B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: -3.70%2016-09 -1.3%2026-06 -3.6%+185.3% over the window
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $-1.1B + TTM dividends $632.1M) ÷ today's market cap ($29B). Same caveat as the cash buyback yield.: -1.52%2016-09 1.0%2026-06 -1.5%-250.6% over the window
