Strong Top-Line Revenue Growth
Revenue grew 10.0% year-over-year to $4.07B in Q1 2026 (from $3.70B in Q1 2025), reflecting broad-based demand across Ecolab's cleaning, sanitizing, and water treatment segments. This growth rate outpaces the prior year's base, suggesting continued pricing power and volume gains.
Operating Leverage Driving Margin Expansion
Operating income increased 12.0% YoY to $622M, slightly outpacing revenue growth of 10.0%, which pushed operating margin modestly higher to 15.3% from 15.0%. SG&A expenses grew at a more modest 5.0% YoY to $1.10B, demonstrating disciplined cost control relative to top-line expansion.
Cost of Revenue Pressure Slightly Outpacing Revenue Growth
Cost of revenue rose 11.4% YoY to $2.30B, marginally faster than the 10.0% revenue growth rate, indicating modest gross margin compression. This reflects ongoing input cost pressures that partially offset the benefits of revenue growth.
