AI Insight: TUSK Ratio Trends

TUSK's profitability metrics swing wildly quarter to quarter, with Q1 2026 showing a rare positive NPM of 23.5% but ROIC remaining deeply negative at -1.3% on a TTM basis of -22.4%.

• Operating margin oscillates violently: -184.0% in Q2 2024, recovering to 0.8% in Q1 2025, then collapsing to -60.9% in Q3 2025.

• NPM turned positive at 23.5% in Q1 2026, a sharp reversal from -85.2% in Q3 2025, suggesting a one-off income item.

• ROIC remains structurally negative across nearly all periods, ranging from -57.1% in Q2 2025 to -1.3% in Q1 2026.

• D/E fell from 0.18 in Q3 2024 to 0.00 in Q4 2024, indicating debt was effectively eliminated within two quarters.

⚠ TTM ROIC of -22.4% signals capital destruction persists despite Q1 2026's positive ROE and ROA readings.

⚠ Q1 2026 NPM of 23.5% sharply diverges from -3.9% operating margin — monitor for non-operating gains masking core weakness.

⚠ Extreme quarterly volatility in all metrics makes trend identification unreliable; watch for two consecutive quarters of positive ROIC.
