- Operating Margin Expansion: Record 18.7% organic operating income margin, up 110bps YoY, driven by mix shift and productivity.
- Legacy Drag Persists: Basic industries and paper remain soft but are expected to stabilize as consolidation slows and innovation gains traction.
Free cash flow and balance sheet strength provide ample capacity for both organic investment and M&A, supporting the company’s multi-year earnings growth targets.
Executive Commentary
"Our growth engines and core businesses represent about 85% of our total sales, and they delivered 4% organic sales growth and mid-teens organic operating income growth. This strong performance more than offset ongoing market softness in our underperforming businesses, basic industries, and paper."
Christophe Beck, President & Chief Executive Officer
"SG&A productivity has been a great story over the last several years. Since 2019, our SG&A leverage has improved 150 basis points, and we're expecting to improve another 20 to 30 basis points this year for full year 2025."

Strategic Positioning
1. Growth Engines: Scaling in High-Value Verticals
Ecolab’s four growth engines—pest elimination, life sciences, global high-tech, and digital—are now the primary source of double-digit growth, expanding at a 12% annual clip and comprising 20% of overall business. Pest elimination’s digital transformation, with over 400,000 intelligent devices deployed, is unlocking a new service model and margin structure. Life sciences is rebounding, with bioprocessing and pharma driving double-digit growth despite capacity constraints. Global high-tech, encompassing data centers and microelectronics, is positioned to double to $900 million with the pending Avivo acquisition, targeting circular water solutions for semiconductor fabs and next-gen cooling for data centers. Ecolab Digital continues rapid expansion, with annualized sales over $380 million and a $13 billion TAM, leveraging AI and subscription models.
2. OneEcolab: Cross-Sell and Enterprise Focus
The OneEcolab strategy, cross-selling across top enterprise customers, is driving above-average growth and margin expansion, especially in institutional specialty and food & beverage. The integration of hygiene and water solutions in North America has led to outsized results, with plans to expand globally and beyond the top 35 customers in 2026. This approach deepens customer relationships and monetizes digital and service innovation, raising the company’s competitive moat.
3. Margin Expansion: Pricing, Productivity, and Mix
Disciplined value pricing (2-3%) and productivity gains from digitalization are key drivers of operating margin expansion, with a clear path to 20% OI margin by 2027. SG&A leverage is expected to deliver 25 to 50 basis points of improvement annually, enabled by technology and the OneEcolab program. Margin gains are being reinvested in high-growth areas, fueling a virtuous cycle of innovation and profitability.
4. Innovation and Digitalization: AI as a Force Multiplier
Breakthrough innovations such as Dish IQ, Aqua IQ, and 3D Tracer for data center cooling are fueling growth and customer retention. Ecolab’s recognition as a top AIQ 50 company underscores its commitment to leveraging AI for both customer-facing and internal productivity applications. Digital solutions are now central to Ecolab’s value proposition, accelerating recurring revenue and providing new monetization pathways.
5. Legacy Businesses: Stabilization and Recovery Plan
Basic industries and paper, though still in decline, are showing signs of stabilization as consolidation slows and innovation is redirected to emerging opportunities (e.g., power, precious metals). The company expects these segments to return to growth in 2026, with the overall portfolio’s breadth providing resilience and upside as the mix shifts toward higher-growth engines.
Key Considerations
Ecolab’s strategic context this quarter is defined by a deliberate shift from legacy cyclical businesses to scalable, high-margin verticals powered by technology and cross-sell opportunities.
Key Considerations:
