These statements are based on the current expectations of management of the Company. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this report. 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 that may affect operating results and business performance are set forth under Item 1A of our most recent Form 10-K, and the Company’s other public filings with the Securities and Exchange Commission.

Item 2.02 Results of Operations and Financial Condition. ​ Ecolab Inc.

The exhibit also reflects changes to the Company’s segment reporting structure, including the movement of certain operating segments, customers and cost allocations effective in the first quarter of 2025. ​ 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, 2025, the Company’s former Global Industrial reportable segment was renamed Global Water and includes the Light & Heavy (previously named Water), Food & Beverage, and Paper operating segments. The Global Institutional & Specialty reportable segment continues to include the Institutional and Specialty operating segments. The Company’s former healthcare operating segment moved into the Institutional operating segment. Global Life Sciences was elevated to a standalone reportable segment. The Global Pest Elimination segment remains a standalone reportable segment. After these changes, the Company has seven 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 2024 and for the twelve months ended December 31, 2024, 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 2024 and 2023 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 2024 and Ecolab’s Annual Reports on Form 10-K filed with respect to the fiscal years ended December 31, 2024 and December 31, 2023. ​ The information in this Current Report on Form 8-K, including the exhibits attached hereto, is fur

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 net sales and operating income information for the years ended December 31, 2023 and December 31, 2022 reflecting international operations at the fixed currency exchange rates established by Company management at the beginning of 2024. The exhibit also reflects changes to the Company’s segment reporting structure, including the movement of certain operating segments, customers and cost allocations effective in the first quarter of 2024. ​ The Company’s organizational structure consists of global business unit and global regional 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, 2024, the Company’s former Textile Care and Colloidal Technologies Group (“CTG”) operating segments are now part of the Water operating segment which continues to remain in the Global Industrial reportable segment. Additionally, the Pest Elimination operating segment, formerly aggregated with the Textile Care and CTG operating segments within Other, is now reported as the stand-alone Global Pest Elimination reportable segment. After these changes, the Company has eight operating segments. ​ The Company is also providing a table (Exhibit 99.2) with supplemental unaudited reportable segment net sales and operating income information for each of the four quarters of 2023 and for the twelve months ended December 31, 2023, 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 2023 and 2022 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 2023 and Ecolab’s Annual Reports on Form 10-K filed with respect to the fiscal years ended December 31, 2023 and December 31, 2022. ​ 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

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 net sales and operating income information for the years ended December 31, 2022 and December 31, 2021 reflecting international operations at the fixed currency exchange rates established by Company management at the beginning of 2023. The exhibit also reflects immaterial changes to the Company’s segment reporting structure, including the movement of certain customers and cost allocations effective in the first quarter of 2023. ​ The Company’s organizational structure consists of global business unit and global regional 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, 2023, the Company’s former Downstream operating segment is now part of the Water operating segment which continues to remain in the global Industrial reportable segment. After this change, the Company has ten operating segments. ​ The Company is also providing a table (Exhibit 99.2) with supplemental unaudited reportable segment net sales and operating income information for each of the four quarters of 2022 and for the twelve months ended December 31, 2022, 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 2022 and 2021 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 2022 and Ecolab’s Annual Reports on Form 10-K filed with respect to the fiscal years ended December 31, 2022 and December 31, 2021. ​ 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 statemen

Item 2.02 Results of Operations and Financial Condition. ​ On February 14, 2023, Ecolab Inc. (“Ecolab”) announced earnings for the fourth quarter ended December 31, 2022.

In connection with the expanded program, Ecolab now expects to incur pre-tax charges of $195 million ($150 million after tax). Ecolab expects that these restructuring actions will be completed by the end of 2024. Program actions include headcount reductions from terminations, not filling certain open positions and facility closures. The expanded program charges are expected to be primarily cash expenditures related to severance and asset disposals. ​ Cautionary Statements Regarding Forward Looking Information. ​ Statements contained in this Current Report on Form 8-K, including statements concerning Ecolab’s restructuring plan, may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based on the current expectations of management of the company. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this report. In particular, the ultimate results of any restructuring and business improvement actions 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 and other business improvement initiatives and the level of success achieved through such actions in improving competitiveness, efficiency and effectiveness. Additional risks and uncertainties that may affect operating results and business performance are set forth under Item 1A of our most recent Form 10-K, and the company’s other public

About Ecolab Inc. (ECL) Earnings

This page provides Ecolab Inc. (ECL) earnings call transcripts from SEC 8-K filings along with AI-powered predictions for post-earnings price movements. Our machine learning models analyze historical earnings data, pre-earnings price patterns, volume changes, and volatility to predict 1-day, 5-day, and 20-day returns after each earnings release.

Earnings transcripts are sourced directly from SEC EDGAR filings. Predictions are generated using gradient boosting models trained on ECL's historical earnings reactions. All predicted returns are shown as percentages, and predicted prices are calculated from the closing price at the time of prediction. Past performance does not guarantee future results.
