AI Insight: HDSN Financial Trends

Severe Q4 2025 deterioration—negative operating income, collapsing cash flow, and operating losses—reverses nine months of profitability gains.

• Operating income swung from +$14M in Q3 2025 to −$11M in Q4 2025, then stabilized near breakeven (+$1M) in Q1 2026.

• Operating cash flow collapsed from +$9M in Q3 2025 to −$33M in Q4 2025 and −$13M in Q1 2026.

• Revenue volatility persists: Q3 2025 peaked at $74M, then fell 41% to $44M in Q4 2025, partially recovering to $60M in Q1 2026.

⚠ Net income turned negative (−$9M) in Q4 2025 after three consecutive profitable quarters; Q1 2026 breakeven raises recovery uncertainty.

⚠ Equity declined from $266M peak (Q3 2025) to $238M (Q1 2026)—driven by recent losses and operating stress.

AI Insight: HDSN Ratio Trends

Hudson Technologies collapsed to near-breakeven profitability in Q1 2026 after severe Q4 2025 losses, with margins and ROIC in free fall.

• Operating margin plummeted from 18.9% in Q3 2025 to -25.2% in Q4 2025, then recovered slightly to 2.4% in Q1 2026.

• ROIC collapsed from 21.0% in Q3 2025 to -18.4% in Q4 2025, remaining deeply depressed at 2.5% in Q1 2026.

• TTM net profit margin of 5.7% masks severe recent deterioration; Q1 2026 NPM of 0.5% reflects ongoing operational strain.

⚠ Extreme quarterly volatility (Q3 2025 OpMargin +18.9% vs Q4 2025 -25.2%) suggests operational instability or significant one-time charges.

⚠ All profitability metrics near zero in Q1 2026; any further deterioration risks technical insolvency given capital structure.
