Item 2.02 Results of Operations and Financial Condition.

Ecolab Inc. ("Ecolab" or the "Company") is providing as an exhibit to this Current Report on Form 8-K a table (Exhibit 99.1) with supplemental unaudited reportable segment information for the years ended December 31, 2025 and December 31, 2024 reflecting international operations at the fixed currency exchange rates established by Company management at the beginning of 2026. The exhibit also reflects changes to the Company's segment reporting structure, including the movement of certain customers and cost allocations effective in the first quarter of 2026.

The Company's organizational structure consists of global business unit and market-based leadership teams. The Company's operating segments follow its commercial and product-based activities and are based on engagement in business activities, availability of discrete financial information and review of operating results by the Chief Operating Decision Maker at the identified operating segment level. Effective January 1, 2026, the Company's former Light & Heavy operating segment was divided into three new operating segments, Heavy Water, Light Water and High-Tech, which continue to remain in the Global Water reportable segment. After these changes, the Company has nine operating segments.

The Company is also providing a table (Exhibit 99.2) with supplemental unaudited reportable segment information for each of the four quarters of 2025 and for the twelve months ended December 31, 2025, reflecting the changes noted above. Ecolab also will publish the attached exhibits on its website located at www.ecolab.com.

The financial information in the tables represents a supplemental presentation of certain of Ecolab's 2025 and 2024 reportable segment information as explained in this Current Report on Form 8-K and is not intended to replace the presentation of such information in Ecolab's Quarterly Reports on Form 10-Q filed with respect to the first, second and third quarters of 2025 and Ecolab's Annual Reports on Form 10-K filed with respect to the fiscal years ended December 31, 2025 and December 31, 2024.

The information in this Current Report on Form 8-K, including the exhibits attached hereto, is furnished and shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section and shall not be deemed incorporated by reference into any registration statement or other document filed with the Securities and Exchange Commission, except as shall be expressly set forth by specific reference in such a filing.

**Notes:**

We evaluate the performance of our non-U.S. dollar functional currency international operations based on fixed currency exchange rates, which eliminate the impact of exchange rate fluctuations on our international operations. Fixed currency amounts are updated annually at the beginning of each year based on translation into U.S. dollars at foreign currency exchange rates established by management, with all periods presented using such rates. The "Fixed Currency Rate Change" columns in the table above reflect international operations at fixed currency exchange rates established by management at the beginning of 2026, rather than the 2025 established rates. The difference between the fixed currency exchange rates and the actual currency exchange rates is reported within the "Effect of foreign currency translation" rows in the table above for net sales and operating income.

------

The "Other" columns in the table above reflect immaterial changes between reportable segments, including the movement of certain customers and cost allocations.

The above table includes financial measures that have not been calculated in accordance with accounting principles generally accepted in the U.S. ("GAAP"), including fixed currency sales, fixed currency cost of sales, fixed currency selling, general and administrative expenses, fixed currency special (gains) and charges, and fixed currency operating income. 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. 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 the table.
