Ecolab ECL recently announced a definitive agreement to acquire CoolIT Systems, a fast-growing leader in advanced liquid cooling solutions for next-generation AI data centers. The deal marks a strategic step to deepen Ecolab’s presence in the high-tech and data center ecosystem, an area seeing strong demand amid the rapid rise of AI-driven computing workloads.
From an investor standpoint, the move positions Ecolab to tap into a large and fast-growing market as data centers increasingly shift toward liquid cooling to handle higher performance requirements. By combining CoolIT’s specialized cooling systems with Ecolab’s strengths in water, chemistry and digital monitoring, it aims to build a more comprehensive, recurring revenue-driven platform, supporting long-term growth and margin expansion.
Likely Trend of ECL Stock Following the News
Following the announcement, the company's shares traded flat in yesterday’s trading. In the past six-month period, shares have lost 3.5% compared with the industry’s 3.7% decline. The S&P 500 has lost 1.4% in the same time frame.
This acquisition meaningfully strengthens Ecolab’s long-term growth profile by positioning it at the center of the rapidly expanding AI data center ecosystem. As workloads become more compute-intensive, the shift toward liquid cooling is inevitable, and CoolIT gives Ecolab a critical foothold in this high-growth, high-margin segment. Beyond immediate revenue contribution, the deal enhances Ecolab’s ability to offer integrated, recurring “Cooling-as-a-Service” solutions, driving deeper customer relationships and cross-selling opportunities.
ECL currently has a market capitalization of $72.3 billion. In the last reported quarter, ECL delivered an earnings surprise of 0.97%.

More on the Acquisition News
CoolIT Systems is a pure-play provider of advanced liquid cooling solutions purpose-built for data centers, with more than 25 years of engineering expertise in thermal management. The company designs and manufactures high-performance technologies such as coolant distribution units (CDUs), cold plates and direct-to-chip cooling systems, which are increasingly critical as AI-driven workloads push computing infrastructure beyond the limits of traditional air cooling. Its solutions are widely used by leading hyperscale and colocation operators, and the company maintains strong relationships with major chip players like NVIDIA and AMD. With expected sales of roughly $550 million over the next 12 months, CoolIT brings both scale and strong growth momentum to the table.
Strategically, the acquisition significantly enhances Ecolab’s positioning in the fast-growing data center market by adding mission-critical cooling hardware to its existing strengths in water, chemistry and digital monitoring. This combination allows Ecolab to offer a more comprehensive, end-to-end “Cooling-as-a-Service” platform, improving performance, reliability and sustainability for customers. The deal also unlocks meaningful cross-selling opportunities across Ecolab’s installed base of more than 1,000 data centers, while deepening relationships with hyperscalers.
Importantly, it doubles Ecolab’s Global High-Tech market opportunity to $10 billion, a space growing at strong double-digit rates, thereby reinforcing a durable long-term growth engine.
From a financial standpoint, Ecolab will acquire CoolIT for approximately $4.75 billion in cash, implying valuation multiples of about 29x near-term EBITDA and 24x projected 2027 EBITDA. The transaction will be funded through new debt, with pro forma net leverage expected to rise to around 3x at closing before trending back to 2x within two years. The deal is expected to be accretive to organic sales growth, adding roughly 1% to Ecolab’s total growth and 2% to its Global Water segment after the first year. While EPS accretion (excluding amortization) is anticipated from 2028, returns are projected to exceed the company’s cost of capital over time. The acquisition is slated to close in the third quarter of 2026, subject to regulatory approvals and customary conditions.
