AI Insight: SNWV Financial Trends

Revenue stalled while profitability collapsed in Q1 2026, erasing recent gains as operating income turned negative.

• Revenue peaked at $13M in Q4 2025, then contracted 23% to $10M in Q1 2026, matching Q1 2025 levels.

• Net income swung from +$10M (Q3 2025) and +$6M (Q4 2025) to -$1M in Q1 2026, reversing nine-month recovery.

• Operating income collapsed from +$3M in Q4 2024 to -$1M in Q1 2026, first negative quarter since inception of data.

• Equity turned positive (+$2M in Q4 2025) but remains near zero in Q1 2026; company still barely solvent.

⚠ Operating cash flow stalled at $0M in Q1 2026 after three consecutive quarters of +$1M–$3M generation.

⚠ Debt held steady ~$26–$29M while equity collapsed to $2M; leverage spike threatens covenant compliance.

AI Insight: SNWV Ratio Trends

Operating margin collapsed to -11.7% in Q1 2026, marking the first negative quarter and a 16.4pp decline from Q4 2025.

• OpMargin deteriorated sharply: 4.7% in Q4 2025 to -11.7% in Q1 2026. NPM and ROA also turned negative.

• ROIC dropped from 8.4% in Q4 2025 to -16.0% in Q1 2026, erasing prior quarter recovery and signaling operational stress.

• Debt/Equity ratio remained elevated at 14.29 in TTM, unchanged from Q4 2025, limiting financial flexibility.

⚠ Q1 2026 profitability collapse across all core metrics (OpMargin, NPM, ROA, ROIC negative) suggests material operational or one-time headwind requiring urgent clarification.

⚠ High volatility in margins and returns across prior quarters (Q3 2025 ROIC 22.5% vs Q1 2026 -16.0%) indicates inconsistent execution or lumpy revenue.
