• Total debt fell sharply from $181M in Q4 2020 to just $3M in Q4 2025, a near-complete deleveraging.
• Equity has deteriorated steadily from $236M in Q4 2021 to $69M in Q4 2025, reflecting persistent losses.
• Revenue was only $2M in both Q3 2025 and Q4 2025, with operating losses of $-8M and $-4M respectively.
