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.: 42.2×2016-12 -19.682026-10 41.62-311.4% over the window

FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: 3.41%2016-09 2.2%2026-06 2.2%+1.0% 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.: 0.97%
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 —.: 0.97%
Dividend/share (fwd)The indicated annual dividend: the last regular payment × payments a year, for a company that pays the same amount each time.: $0.24
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 72.6M ÷ 72.2M. 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.: -0.63%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-0.63%) + dividends paid over that year ($17.2M) ÷ market_cap_at(2025-06-30) ($1.4B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: 0.60%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($22.8M) ÷ today's market cap ($1.8B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 1.28%2016-09 -1.8%2026-06 0.8%-147.5% over the window
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $22.8M + TTM dividends $17.2M) ÷ today's market cap ($1.8B). Same caveat as the cash buyback yield.: 2.24%2016-09 -1.8%2026-06 1.5%-183.3% over the window
