AI Insight: ALTO Ratio Trends
ALTO snapped a five-quarter loss streak in Q3 2025, but Q1 2026 profitability retreated sharply from that peak, signaling fragile, uneven recovery.
• Operating margin swung from -16.6% in Q4 2024 to +7.0% in Q3 2025, then faded to +1.1% in Q1 2026.
• ROE recovered from -74.1% in Q4 2024 to +35.6% in Q4 2025, but collapsed back to +6.8% in Q1 2026.
• Leverage peaked at D/E 0.60 in Q2 2025 and has since declined to 0.38 in Q1 2026 — a meaningful deleveraging trend.
• TTM ROIC of 5.5% marks the first positive trailing return on invested capital after four consecutive quarters of negative ROIC.
⚠ Q1 2026 operating margin of 1.1% is well below Q3 2025's 7.0% peak — seasonal weakness or structural margin pressure warrants monitoring.
⚠ Q4 2024 saw a severe ROE spike to -74.1%; any recurrence of one-off impairments could quickly reverse the recovery.
⚠ D/E trending down to 0.38 is positive, but absolute improvement depends on sustained operating profitability holding above breakeven.
