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.: -28.3×2017-12 -25.142026-10 -28.90+15.0% over the window
Fwd P/E: -174.1×
P/S (ttm)Market cap ÷ TTM revenue.: 24.7×2021-12 159.262026-10 24.74-84.5% over the window
P/B (mrq)Market cap ÷ stockholders' equity at the most recent quarter end.: 57.6×2017-12 -15.292026-10 57.63-476.9% over the window
EV/Sales (ttm): 23.8×
FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: -1.97%2017-09 -3.5%2025-12 -1.6%-54.5% over the window
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 68.9M ÷ 66.4M. 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.: -3.66%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-3.66%) + dividends paid over that year ($0) ÷ market_cap_at(2025-06-30) ($4.2B). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: -3.66%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($-1K) ÷ today's market cap ($5.9B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: -0.00%2017-09 0.0%2026-06 -0.0%
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $-1K + TTM dividends $0) ÷ today's market cap ($5.9B). Same caveat as the cash buyback yield.: -0.00%2017-09 0.0%2026-06 -0.0%
