Bottom line
No cash-flow valuation
Model read-out from the numbers below, not advice. Score -1 (DCF counts double).

Discounted cash flow

Trailing free cash flow is negative or missing, so a cash-flow DCF isn't meaningful by default. You can enter your own assumptions below.
Reverse DCFfor context, not a signal
Trailing free cash flow is zero or negative, so there's no growth rate to solve for. The price is betting on a turnaround to positive cash flow.

Your value per share–

Free cash flow = operating cash flow − capital spending, trailing 12 months (TTM to 2026-06-30). Growth default: average of 3-year revenue CAGR and latest revenue growth, capped at 30%. Years 6–10 fade linearly to terminal growth. Discount rate = 4.25% risk-free assumption + beta 1.00 (n/a) × 5% equity premium, kept within 7–13%. Bear: lower growth, +1 pt discount, 2% terminal. Bull: higher growth, −1 pt, 3%.
