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.: 8.9×2016-12 -4.362026-10 9.12-309.1% over the window

FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: 1.65%2016-09 -8.6%2026-06 1.0%-111.9% over the window
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 48.4M ÷ 45.2M. 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.: -7.27%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-7.27%) + dividends paid over that year ($0) ÷ market_cap_at(2025-06-30) ($1.7B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: -7.27%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($0) ÷ today's market cap ($1.2B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 0.00%2016-09 0.0%2026-06 0.0%
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $0 + TTM dividends $0) ÷ today's market cap ($1.2B). Same caveat as the cash buyback yield.: 0.00%2016-09 0.0%2026-06 0.0%
