• Operating income margin held steady around 15–17% through 2025, but Q1 2026 margin of 15.3% shows no improvement.

• Operating cash flow strengthened to $1,090M in Q4 2025 but fell to $446M in Q1 2026, the weakest since Q1 2025.

AI Insight: ECL Ratio Trends

Ecolab's profitability and returns have deteriorated sharply in Q1 2026, erasing most of 2025's operational gains.

⚠ Q3 2025 spike (26.1% OpMargin, 24.9% ROIC) appears unsustainable; Q4–Q1 reversal suggests one-off drivers.
