Cautionary statement Forward-Looking Information This communication contains forward looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements regarding macroeconomic conditions and our financial and business performance and prospects, including sales, earnings, special (gains) and charges, raw material costs, margins, pricing, currency translation, productivity, investments and new business. These statements are based on the current expectations of management. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this communication. In particular, the ultimate results of any restructuring initiative depend on a number of factors, including the development of final plans, the impact of local regulatory requirements regarding employee terminations, the time necessary to develop and implement the restructuring initiatives and the level of success achieved through such actions in improving competitiveness, efficiency and effectiveness. Additional risks and uncertainties are set forth under Item 1A of our most recent Form 10-K, and our other public filings with the Securities and Exchange Commission (“SEC”), and include the impact of economic factors such as the worldwide economy, interest rates, foreign currency risk, reduced sales and earnings in our international operations resulting from the weakening of local currencies versus the U.S. dollar, demand uncertainty, supply chain challenges and inflation; the vitality of the markets we serve; exposure to global economic, political and legal risks related to our international operations, including international trade policies, geopolitical instability and the escalation of armed conflicts; our ability to successfully execute organizational change and management transitions; information technology infrastructure failures or breaches in data security; difficulty in procuring raw materials or fluctuations in raw material costs; our increasing reliance on artificial intelligence technologies in our products, services and operations; the occurrence of severe public health outbreaks not limited to COVID-19; our ability to acquire complementary businesses and to effectively integrate such businesses; our ability to execute key business initiatives; our ability to successfully compete with respect to value, innovation and customer support; the costs and effect of complying with laws and regulations; the occurrence of litigation or claims, including class action lawsuits; and other uncertainties or risks reported from time to time in our reports to the SEC. In light of these risks, uncertainties and factors, the forward-looking events discussed in this communication may not occur. We caution that undue reliance should not be placed on forward-looking statements, which speak only as of the date made. Ecolab does not undertake, and expressly disclaims, any duty to update any forward-looking statement, except as required by law. Non-GAAP Financial Information This communication includes Company information that does not conform to generally accepted accounting principles (GAAP).

Expect to deliver continued 12-15% EPS growth 3 Reported sales +4%, with accelerating pricing and continued volume growth Strong organic OI margin expansion, confident in delivering a 20% margin by 2027 Reported diluted EPS $2.05; adjusted diluted EPS $2.07, +13% Continue to expect 12-15% adjusted EPS growth in 2025 and beyond ▪ Organic sales +3%, driven by value price accelerating to 3% from 2% and continued 1% volume growth. ▪ Core performance was led by continued strong growth in Institutional & Specialty and accelerating growth in Food & Beverage. Ongoing soft market demand in Basic Industries and Paper was mitigated by good new business wins. ▪ Ecolab’s growth engines, which include Life Sciences, Pest Elimination, Global High-Tech and Ecolab Digital, collectively grew double-digits. ▪ Reported OI -27%, reflecting the comparison to last year’s gain on the sale of the global surgical solutions business. Organic OI +10%. ▪ Reported OI margin 18.3%. Organic OI margin 18.7%, +110 bps as solid sales growth and improved productivity was partially offset by growth-oriented investments in the business. ▪ As expected, Ecolab delivered another strong quarter of double-digit EPS growth. ▪ Performance was driven by accelerating pricing, volume growth, and continued strong organic operating income margin expansion. ▪ 2025: Ecolab is sharpening its 2025 adjusted EPS range to between $7.48 and $7.58, +12% to 14%. ▪ 4Q 2025: Expect fourth quarter 2025 adjusted diluted earnings per share in the $2.02 to $2.12 range, +12% to 17%.

3Q overview ▪ Solid performance with reported sales +4% o Pricing accelerated to +3%, supported by ongoing customer value delivery. o Volume +1%, driven by good new business and breakthrough innovation. ▪ Organic growth led by Institutional & Specialty, Pest Elimination, and Life Sciences o Water +2%, accelerating Food & Beverage sales and continued double-digit growth in Global High-Tech more than offset a 2% headwind from Basic Industries and Paper. o Institutional & Specialty remained strong at +4%, reflecting continued good growth in hospitality and modestly lower sales to hospitals. o Pest Elimination +6%, fueled by the One Ecolab growth strategy. o Life Sciences +6%, led by strong double-digit growth in bioprocessing and pharmaceutical sales. ▪ Reported diluted EPS $2.05 ▪ Adjusted diluted EPS $2.07, +13% o Strong performance was fueled by accelerating pricing, continued volume growth, and strong organic operating income margin expansion. Sales EPS 4

Expect Strong Finish To 2025, 12-15% EPS Growth in 2026 4Q 2025 ▪ Ecolab expects fourth quarter 2025 adjusted diluted earnings per share in the $2.02 to $2.12 range, rising 12% to 17% compared with adjusted diluted earnings per share of $1.81 a year ago. ▪ Secular growth trends in water, hygiene, infection prevention, and digital technologies continue to fuel resilient, long-term demand for Ecolab’s innovative technologies and services. Strong momentum in Ecolab’s growth engines, which include Life Sciences, Pest Elimination, Global High-Tech and Ecolab Digital, is expected to continue. Ecolab’s investments in these areas position the company well to capitalize on these attractive long-term high-growth, high-margin opportunities. ▪ In the near-term, the global operating environment remains unpredictable, characterized by constantly evolving geopolitics and international trade policy, which are impacting end-market demand. Importantly, with these dynamic macroeconomic conditions, Ecolab’s confidence in its earnings growth trajectory is strong. The company remains focused on outperforming its end markets by delivering best-in-class value to customers, leveraging its One Ecolab growth strategy and its record breakthrough innovation pipeline. ▪ As a result, Ecolab is sharpening its 2025 adjusted EPS range to between $7.48 and $7.58, rising 12% to 14% compared with adjusted diluted earnings per share of $6.65 in 2024. 5

7 Sales +2% Light & Heavy All sales figures are organic unless otherwise noted Global Water Segment Q4: Expect modest sales growth as continued strong double-digit growth in Global High-tech more than offsets softer demand in Basic Industries. ▪ Growth in light and heavy reflected continued strong double-digit growth in Global High-tech and accelerating manufacturing sales growth, which more than offset ongoing soft end market demand in Basic Industries. o Manufacturing: Accelerating sales growth driven by continued good momentum in food & beverage, leveraging the One Ecolab enterprise selling strategy. o Basic Industries: Sales modestly declined as further new business wins were more than offset by continued soft end market demand in primary metals and chemicals. o High-tech: Continued strong double-digit sales growth driven by attractive share gains from our innovative cooling technologies for data centers and circular water programs for microelectronics. o Downstream: Stable sales reflected continued growth in North America, offset by softer sales in other international regions. ▪ The impact of increasing water demand, which is being amplified by the rapid build out of artificial intelligence infrastructure, continues to be a critical issue for our customers, and one that Ecolab is uniquely positioned to help them solve. Our innovative circular water solutions, digital technologies, and service expertise help our customers improve their performance, significantly reduce water consumption, and meet their sustainability objectives.

8 Sales -4% Paper All sales figures are organic unless otherwise noted Global Water Segment Sales +4% Food & Beverage Q4: Anticipate good sales growth as strong new business wins and value pricing continue to outperform industry trends. ▪ Organic sales growth accelerated as new business wins and value pricing outperformed industry trends. Growth was led by good gains in beverage, dairy, and food. ▪ Regionally, North America, Latin America, and IMEA delivered strong growth, while sales in Europe and Asia Pacific were rather stable. ▪ We continue to benefit from our One Ecolab enterprise selling approach to customers, where we combine our industry-leading cleaning and sanitizing, water treatment and digital technologies to deliver significant customer value through improved food safety, lower operating costs and water usage optimization. Q4: Expect modestly lower sales as new business wins are offset by continued soft customer production rates. ▪ As expected, sales were modestly lower as continued new business wins were offset by continued soft customer production rates. ▪ Solid growth in tissue and towel was offset by softer demand in packaging. ▪ While soft customer production rates continue to present challenging market dynamics, our strong new business wins are largely mitigating these unfavorable market impacts. Good share gains continue to be driven by new innovation and our global service expertise, which help our customers improve their performance, optimize their costs, and reduce their water consumption.

9 Sales +3% Institutional Sales +7% Specialty All sales figures are organic unless otherwise noted Global Institutional & Specialty Segment Q4: We expect continued growth in hospitality, partially offset by modestly lower sales to hospitals. ▪ Beginning in 2025, Ecolab’s healthcare business is being reported within the Institutional division. As expected, continued good growth in sales to hospitality customers was partially offset by modestly lower sales to hospitals. o Hospitality: Good growth continues to be driven by value pricing and attractive new business wins from our One Ecolab growth initiative. Growth continues to outperform end market trends as customers leverage our innovative products and service expertise that help improve performance, optimize labor, and reduce total costs. o Hospitals: Modestly lower organic sales reflected continued non-strategic, low margin business exits, which were partially offset by good value pricing. Our new business efforts are focused on attractive long-term growth opportunities in the infection prevention and instrument reprocessing areas to drive profitable long-term growth. ▪ We remain focused on driving attractive long-term growth by capitalizing on One Ecolab growth opportunities and harnessing digital innovations like DishIQ, KitchenIQ, and AquaIQ. These efforts are delivering enhanced total customer value and generating attractive new business wins for Ecolab. Q4: Expect continued strong sales growth driven by strong new business wins. ▪ As expected, Specialty delivered strong sales growth as robust new business wins more than offset the impact from previously disclosed non-strategic, low margin business exits. Strong fundamental performance continued to significantly outperform market trends. o Quick Service: Continued strong growth reflected good new business and our ongoing product and digital innovation that delivers leading food safety outcomes, labor optimization and lower total operating costs.​ Demand across the quick service industry for our labor and cost optimization technologies continues to be strong, which we are uniquely positioned to capture. o Food Retail: Sales growth accelerated, reflecting improved new business wins. These good wins are being driven by our One Ecolab growth initiative and new product and digital innovation. As a trusted food safety partner for retailers, we continue to expand our competitive differentiation by helping our customers protect their brand, improve their customer experience, and optimize their operational performance.

10 Sales +6% Pest Elimination All sales figures are organic unless otherwise noted Global Pest Elimination Segment ▪ Continued strong organic growth was led by good gains in food & beverage, restaurants, and healthcare, which benefited from our One Ecolab enterprise selling approach. ▪ To fuel continued, strong long-term growth and market share gains, our focus is on rapidly accelerating the rollout of our digital pest intelligence program to provide customers with enhanced service and value. This leading digital offering, along with our high service levels, are expanding the total value delivered to customers, extending our competitive advantages, and enhancing our long-term growth opportunities. Q4: Expect continued strong growth, benefiting from new customer wins as we leverage our investments in pest intelligence.

11 Sales +6% Life Sciences All sales figures are organic unless otherwise noted Global Life Sciences Segment Q4: Expect solid growth as good new business momentum and progressively improving industry trends overcome comparisons to last year’s very strong growth in bioprocessing sales. ▪ Accelerating sales growth reflected continued good new business wins that leverage our innovation, investments in new capabilities, and progressively improving industry trends. ▪ Continued double-digit growth in bioprocessing and pharmaceutical & personal care overcame ongoing capacity constraints within Life Sciences’ industrial water purification business. ▪ The long-term growth opportunities for the Life Sciences industry are very attractive. We continue to invest and innovate to further expand our global capabilities and technical expertise across contamination control and purification technologies including bioprocessing to capitalize on this long-term growth opportunity.

Segment operating income performance ▪ Organic operating income increased 2% as sales growth and improved productivity overcame growth-oriented investments in the business. ▪ Global Water’s underlying performance was strong when excluding Basic Industries and Paper, which together reduced organic operating income growth by low double digits. ▪ Organic operating income increased 11% as strong sales growth was partially offset by growth-oriented investments, including pest intelligence.

20 Non-GAAP Financial Information: This communication and certain of the accompanying tables include financial measures that have not been calculated in accordance with accounting principles generally accepted in the U.S. (“GAAP”). These non-GAAP financial measures include: • fixed currency sales • organic sales • adjusted cost of sales • adjusted gross profit • adjusted gross margin • fixed currency operating income • adjusted operating income • adjusted fixed currency operating income • adjusted fixed currency operating income margin • organic operating income • organic operating income margin • adjusted tax rate • adjusted net income attributable to Ecolab • adjusted diluted earnings per share • EBITDA • Adjusted EBITDA We provide these measures as additional information regarding our operating results. We use these non-GAAP measures internally to evaluate our performance and in making financial and operational decisions, including with respect to incentive compensation. We believe that our presentation of these measures provides investors with greater transparency with respect to our results of operations and that these measures are useful for period-to-period comparison of results. Non-GAAP financial information

21 Non-GAAP Financial Information (Continued): Our non-GAAP financial measures for adjusted cost of sales, adjusted gross margin, adjusted gross profit and adjusted operating income exclude the impact of special (gains) and charges and our non-GAAP financial measures for adjusted tax rate, adjusted net income attributable to Ecolab and adjusted diluted earnings per share further exclude the impact of discrete tax items. We include items within special (gains) and charges and discrete tax items that we believe can significantly affect the period-over-period assessment of operating results and not necessarily reflect costs and/or income associated with historical trends and future results. After tax special (gains) and charges are derived by applying the applicable local jurisdictional tax rate to the corresponding pre-tax special (gains) and charges. EBITDA is defined as net income including non-controlling interest with the sum of provision for income taxes, net interest expense, depreciation and amortization added back. Adjusted EBITDA further adds back special (gains) and charges impacting EBITDA. EBITDA and adjusted EBITDA are used in our net debt to EBITDA and net debt to adjusted EBITDA ratios, which we view as important indicators of the operational and financial health of our organization. We evaluate the performance of our international operations based on fixed currency rates of foreign exchange, which eliminate the translation impact of exchange rate fluctuations on our international results. Fixed currency amounts included in this release are based on translation into U.S. dollars at the fixed foreign currency exchange rates established by management at the beginning of 2025. We also provide our segment results based on public currency rates for informational purposes. Our reportable segments do not include the impact of intangible asset amortization from the Nalco and Purolite transactions or the impact of special (gains) and charges as these are not allocated to the Company’s reportable segments. Our non-GAAP financial measures for organic sales, organic operating income and organic operating income margin are at fixed currency and exclude the impact of special (gains) and charges, the results of our acquired businesses from the first twelve months post acquisition and the results of divested businesses from the twelve months prior to divestiture. Further, due to the sale of the global surgical solutions business on August 1, 2024, we have excluded the results of the business for the nine-month period ended September 30, 2024 from these organic measures to remain comparable to the corresponding periods in 2025. In addition, as part of the separation of ChampionX in 2020, we continue to provide certain products to ChampionX, which are recorded in product and equipment sales in the Global Water segment along with the related cost of sales. These transactions are removed from the consolidated results as part of the calculation of the impact of acquisitions and divestitures. These non-GAAP financial measures are not in accordance with, or an alternative to, GAAP and may be different from non-GAAP measures used by other companies. Investors should not rely on any single financial measure when evaluating our business. We recommend that investors view these measures in conjunction with the GAAP measures included in this news release. Reconciliations of our non-GAAP measures are included in the following “Non-GAAP Financial Measures” tables of this communication. We do not provide reconciliations for non-GAAP estimates on a forward-looking basis (including those contained in this news release) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of various items that have not yet occurred, are out of our control and/or cannot be reasonably predicted, and that would impact reported earnings per share and the reported tax rate, the most directly comparable forward-looking GAAP financial measures to adjusted earnings per share and the adjusted tax rate. For the same reasons, we are unable to address the probable significance of the unavailable information. Non-GAAP financial information (cont.)
