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.: -28.0×2022-09 -78.732026-10 -30.35-61.5% over the window
Fwd P/E: 76.2×
P/B (mrq)Market cap ÷ stockholders' equity at the most recent quarter end.: 8.8×2022-09 10.252026-10 8.81-14.0% over the window
FCF yield (ttm)TTM free cash flow ÷ market cap — the inverse of P/FCF.: -5.28%2022-12 -2.3%2026-06 -2.9%+25.8% over the window
Buyback yield (realized, 1y)1 − shares_at(2026-06-30) ÷ shares_at(2025-06-30) = 1 − 146.1M ÷ 125.1M. 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.: -16.81%
Shareholder yield (realized, 1y)Buyback leg + dividend leg: shares retired over the year (-16.81%) + dividends paid over that year ($0) ÷ market_cap_at(2025-06-30) ($526.6M). Both legs are measured against the start of the window, so a payout can't shrink its own denominator.: -16.81%
Buyback yield (cash, ttm)Buybacks net of issuance over the trailing twelve months ($18.2M) ÷ today's market cap ($1.1B). Dollars SPENT over what the company is worth NOW — a stock that fell after buying reads high.: 1.64%2022-12 -11.6%2026-06 0.9%-107.7% over the window
Shareholder yield (cash, ttm)(TTM buybacks net of issuance $18.2M + TTM dividends $0) ÷ today's market cap ($1.1B). Same caveat as the cash buyback yield.: 1.64%2022-12 -11.6%2026-06 0.9%-107.7% over the window
