AI Insight: CLSK Financial Trends

Debt surged from near-zero to $1,788M while equity collapsed 55% from its peak, signaling severe balance-sheet deterioration into Q1 2026.

• Total debt exploded from $7M in Q3 2024 to $1,788M by Q1 2026, a 255x increase in five quarters.

• Equity peaked at $2,175M in Q3 2025 then cratered to $986M in Q1 2026, a $1,189M decline in two quarters.

• Operating cash flow worsened every period, from -$35M in Q1 2024 to -$161M in Q4 2025, a near-5x deterioration.

• Operating income swung from +$389M in Q1 2025 to -$317M in Q4 2025, a $706M reversal within three quarters.

⚠ Debt held at $1,788M into Q1 2026 while equity fell to $986M — debt now exceeds equity, a first in this dataset.

⚠ Revenue data is absent from Q1 2025 onward, making top-line trajectory impossible to assess.

⚠ Persistently negative operating cash flow alongside rising debt raises near-term liquidity and refinancing risk.

AI Insight: CLSK Ratio Trends

CleanSpark's leverage surged from 0.00 to 1.81x D/E by Q1 2026 while ROIC collapsed to -40.0% in Q4 2025, signaling a sharply deteriorating risk profile.

• D/E ratio jumped from 0.00 in Q3 2024 to 1.29 in Q4 2025 and further to 1.81 in Q1 2026, indicating rapid debt accumulation.

• ROE turned deeply negative at -109.6% in Q4 2025 after a strong +103.0% reading in Q1 2025, reflecting extreme earnings volatility.

⚠ D/E at 1.81x in Q1 2026 — up from zero in 2024 — monitor whether debt-financed expansion translates into operational returns.

⚠ OpMargin data is absent for six of nine periods; limited margin visibility makes profitability assessment difficult.

⚠ Q1 2025 ROA of 73.3% vs. Q4 2025 ROA of -45.5% suggests Bitcoin-price sensitivity driving severe quarter-to-quarter swings.
