AI Insight: AMTX Financial Trends

Debt surged to $405M in Q1 2026 while equity deteriorated to -$321M, leaving Aemetis deeply insolvent with no quarter of positive net income across the entire period.

• Total debt rose steadily from $309M in Q2 2024 to $405M in Q1 2026, a $96M increase over six quarters with no sign of stabilization.

• Operating losses narrowed from -$14M in Q2 2024 to -$2M in Q4 2025 before widening again to -$6M in Q1 2026.

• Operating cash flow turned positive at $3M in Q3 2025 and $6M in Q4 2025, the only two quarters of positive OCF in the dataset, then reversed to -$11M in Q1 2026.

• Equity deteriorated from -$249M in Q2 2024 to -$321M in Q1 2026, deepening insolvency by $72M over the period.

⚠ Debt jumped $23M in a single quarter to $405M in Q1 2026 — the largest quarterly increase in the dataset — raising refinancing risk.

⚠ Revenue declined to $43M in Q1 2025 and Q4 2025, the lowest readings; Q1 2026 recovery to $55M warrants monitoring for sustainability.

⚠ OCF swung sharply from +$6M in Q4 2025 to -$11M in Q1 2026 — the worst reading in two quarters — reversing a tentative improvement.

AI Insight: AMTX Ratio Trends

AEMETIS remains deeply unprofitable across all metrics, though Q4 2025 showed a sharp but potentially seasonal margin improvement that has since partially reversed.

• Operating margin improved dramatically from -36.3% in Q1 2025 to -5.7% in Q4 2025, then deteriorated to -11.6% in Q1 2026.

• ROA swung from -40.5% in Q1 2025 to -8.2% in Q4 2025, but rebounded negatively to -32.1% in Q1 2026, signaling no sustained recovery.

• ROIC remained severely negative, ranging from -13.2% in Q4 2025 to -90.6% in Q2 2024, indicating persistent capital destruction.

⚠ Q4 2025's anomalously strong margins (-5.7% OpMargin, -12.3% NPM) warrant scrutiny — likely seasonal or one-off, not structural improvement.

⚠ Net profit margin remains deeply negative at -39.8% in Q1 2026, far worse than operating margin, signaling heavy below-the-line financing costs.

⚠ ROE and D/E are unavailable across all periods, obscuring leverage risk for a capital-intensive biofuels operator.
