Fiscal period ending 2025-12-31 versus 2024-12-31view filing on EDGAR →

A delisting threat, $785M–$949M impairment charges, suspended DOE loan activities, and newly explicit going-concern/liquidity pressure collectively mark a severe deterioration in the company's financial and operational risk profile. Worsening spans every major theme — liquidity, capital structure, operations, regulatory, and competitive — with only modest, largely technical offsets in debt reduction and improved (but still deeply negative) cash burn. The combination of stock price collapse ($18.88 to $0.69 low), 230M warrants outstanding, and reliance on asset monetizations signals acute near-term solvency risk.
