Sales EPS 4

Expect 12-15% EPS growth and accelerating organic sales growth 2Q 2026 ▪ Ecolab expects second quarter 2026 adjusted diluted earnings per share in the $2.02 to $2.12 range, rising 7% to 12% compared with adjusted diluted earnings per share of $1.89 a year ago. This range reflects a short transition period as benefits from the energy surcharge progressively build to offset higher commodity costs. ▪ Long-term growth trends in water, hygiene, infection prevention, and digital technologies continue to fuel resilient demand for Ecolab’s innovative technologies and services. Strong momentum in Ecolab’s growth engines, which include Global High-Tech, Life Sciences, Pest Elimination and Ecolab Digital, is expected to continue to strengthen Ecolab’s overall performance. ▪ While the external environment remains dynamic, Ecolab’s team has demonstrated it can adjust quickly to deliver high performance in almost any environment. With this, Ecolab’s confidence in its performance trajectory remains strong. As the company exits the second quarter, it expects accelerating pricing to cover the dollar impact from higher commodity costs, with gross margin stabilizing in the second half of the year. With this, organic sales growth is expected to accelerate to the 6% to 7% range in the second half of the year. The company anticipates adjusted operating income margin to expand to approximately 19% in 2026, resulting in adjusted operating income growth of 14% to 16%. ▪ As a result, Ecolab continues to expect full year 2026 adjusted diluted earnings per share in the $8.43 to $8.63 range, rising 12% to 15% compared with adjusted diluted earnings per share of $7.53 in 2025. ▪ This outlook excludes the impact of the recently announced acquisition of CoolIT Systems, which is expected to close during the third quarter. 5

22 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 may include: • fixed currency sales • organic sales • adjusted cost of sales • adjusted gross profit • adjusted gross margin • fixed currency operating income • fixed currency operating income margin • 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

23 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 presentation are based on translation into U.S. dollars at the fixed foreign currency exchange rates established by management at the beginning of 2026. 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, Purolite and Ovivo Electronics 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 where applicable, 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. 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 presentation. 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 presentation) 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.)
