One Ecolab

​

On July 30, 2024, the Company announced the One Ecolab initiative, which will enhance its growth and margin expansion journey. As a program within this initiative, the Company also announced that it commenced a restructuring plan to leverage its digital technologies to realign the functional work done in many countries into global centers of excellence. The Company anticipates restructuring costs of $175 million ($136 million after tax) and special charges of $50 million ($39 million after tax) by the end of 2027. The Company anticipates that the restructuring costs will primarily be cash expenditures for severance costs relating to team reorganization.

​

The Company recorded restructuring charges of $17.4 million ($13.2 million after tax) and $56.8 million ($43.7 million after tax) during the second quarter and first six months of 2025, respectively, primarily related to severance. In addition, the Company recorded non-restructuring special charges of $11.6 million ($8.8 million after tax) and $16.4 million ($12.4 million after tax) during the second quarter and first six months of 2025, respectively, primarily related to professional services. The Company has recorded $138.6 million ($106.7 million after tax) of cumulative restructuring charges and $40.1 million ($30.3 million after tax) of cumulative special charges under the One Ecolab initiative.

​

The restructuring liability related to the One Ecolab initiative was $82.1 million and $54.9 million as of June 30, 2025 and December 31, 2024, respectively. The remaining liability is expected to be paid over a period of a few months to several quarters and will continue to be funded from operating activities.

Other restructuring

​

Other restructuring is primarily related to the Combined Program, which is described below. These activities have been included as a component of cost of sales and special (gains) and charges on the Consolidated Statements of Income. Restructuring liabilities have been classified as a component of other current and other noncurrent liabilities on the Consolidated Balance Sheets.

​

Combined Program

​

In November 2022, the Company approved a Europe cost savings program and subsequently expanded the program to focus on its Institutional and Healthcare businesses in other regions (the “Combined Program”). The restructuring activities were completed at the end of 2024, with total costs $184.1 million ($151.5 million after tax). Subsequent to the completion of the Combined Program, the Company finalized the sale of a facility, resulting in a gain of $12 million ($9.2 million after tax) in the second quarter of 2025.

​

The net liability related to the Combined Program was $4.4 million and $12.8 million as of June 30, 2025 and December 31, 2024, respectively. Net cash payments were $1.2 million and $8.3 million in the second quarter and first six months of 2025, respectively. The remaining liability is expected to be paid over a period of a few months to several quarters and will continue to be funded from operating activities.

3. ACQUISITIONS

​

The Company makes business acquisitions that align with its strategic business objectives. The assets and liabilities of acquired businesses are recorded in the Consolidated Balance Sheets based on estimates of the fair value of assets acquired, liabilities assumed and noncontrolling interests acquired as of the acquisition date. Goodwill is recognized in the amount that the purchase consideration paid exceeds the fair value of the net assets acquired. Purchase consideration includes both cash paid and the fair value of noncash consideration exchanged, including stock and/or contingent consideration, and is reduced by the amount of cash or cash equivalents acquired.

​

In May 2024, the Company completed an immaterial acquisition which became part of the Global Pest Elimination reporting segment. The purchase accounting for this acquisition was finalized in the second quarter of 2025.

​

No acquisitions occurred during the first six months of 2025 or the first quarter of 2024. The following table summarizes the acquisition date fair value of net assets acquired from the Company’s acquisitions during the second quarter of 2024:

Public Notes and Other

​

In June 2025, the Company issued $500 million aggregate principal three-year fixed rate notes with a coupon rate of 4.30%, and an effective interest rate of 4.36%. The proceeds were used for general corporate purposes.

​

The Company’s public notes may be redeemed by the Company at its option at redemption prices that include accrued and unpaid interest and a make-whole premium. Upon the occurrence of a change of control accompanied by a downgrade of the public notes below investment grade rating, within a specified time period, the Company would be required to offer to repurchase the public notes at a price equal to 101% of the aggregate principal amount thereof, plus any accrued and unpaid interest to the date of repurchase. The public notes are senior unsecured and unsubordinated obligations of the Company and rank equally with all other senior and unsubordinated indebtedness of the Company.

​

In June 2025, one of the Company’s Chinese subsidiaries entered into a construction loan facility that provides up to 1.1 billion in Chinese Yuan (“CNY”) ($156 million) of proceeds to fund capital expenditures. This loan facility has a tenor of 13 years and is secured by certain assets of its Chinese subsidiaries. Any borrowings under this facility are included in Finance lease obligations and other in the table above.

GOODWILL AND OTHER INTANGIBLE ASSETS

6. GOODWILL AND OTHER INTANGIBLE ASSETS

​

Goodwill

​

Goodwill arises from the Company’s acquisitions and represents the excess of the fair value of the purchase consideration exchanged over the fair value of net assets acquired. The Company’s reporting units are its seven operating segments. The Company assesses goodwill for impairment on an annual basis during the second quarter. If circumstances change or events occur that demonstrate it is more likely than not that the carrying amount of a reporting unit exceeds its fair value, the Company completes an interim goodwill assessment of that reporting unit prior to the next annual assessment. If the results of an annual or interim goodwill assessment demonstrate the carrying amount of a reporting unit is greater than its fair value, the Company will recognize an impairment loss for the amount by which the reporting unit’s carrying amount exceeds its fair value, but not to exceed the carrying amount of goodwill assigned to that reporting unit.

​

During the second quarter of 2025, the Company completed its annual goodwill impairment assessment for its reporting units using discounted cash flow analyses that incorporated assumptions regarding future growth rates, terminal values and discount rates. The Company’s goodwill impairment assessments for 2025 indicated the estimated fair values of each of these seven reporting units exceeded the carrying amounts of the respective reporting unit by a significant margin. There has been no impairment of goodwill in any of the periods presented.

​

The changes in the carrying amount of goodwill for each of the Company's reportable segments during the second quarter ended June 30, 2025 were as follows:

(a)Relates to reclassifications made to reportable segments in the current year. 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.

​

(b)Represents measurement period adjustments to purchase price allocations for acquisitions deemed preliminary as of the end of the prior year.

​

Other Intangible Assets

​

The Nalco trade name is the Company’s only indefinite life intangible asset, which is tested for impairment on an annual basis during the second quarter. During the second quarter of 2025, the Company completed its annual impairment assessment of the Nalco trade name using the relief from royalty discounted cash flow method, which incorporates assumptions regarding future sales projections, royalty rates and discount rates. The Company’s Nalco trade name impairment assessment for 2025 indicated the estimated fair value of the Nalco trade name exceeded its $1.2 billion carrying amount by a significant margin. There has been no impairment of the Nalco trade name intangible since it was acquired.

​

The Company’s intangible assets subject to amortization include customer relationships, trademarks, patents and other technologies primarily acquired through business acquisitions. The fair value of intangible assets acquired in business acquisitions are estimated primarily using discounted cash flow valuation methods at the time of acquisition. Intangible assets are amortized on a straight-line basis over their estimated lives. Total amortization expense related to intangible assets during the second quarter of 2025 and 2024 was $75.0 million and $75.1 million, respectively, and during the first six months of 2025 and 2024 was $149.9 million and $152.9 million, respectively. Amortization expense related to intangible assets for the remaining six-month period of 2025 is expected to be approximately $150.1 million.

​

The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, contingent consideration obligations, commercial paper, notes payable, foreign currency forward contracts, interest rate swap agreements, cross-currency swap derivative contracts and long-term debt.

​

Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. A hierarchy has been established for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring the most observable inputs be used when available. The hierarchy is broken down into three levels:

​

Level 1 - Inputs are quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

Level 2 - Inputs include observable inputs other than quoted prices in active markets.

Level 3 - Inputs are unobservable inputs for which there is little or no market data available.

​

The carrying amount and the estimated fair value for assets and liabilities measured on a recurring basis were:

The carrying value of foreign currency forward contracts is at fair value, which is determined based on foreign currency exchange rates as of the balance sheet date and classified within Level 2. The carrying value of interest rate swap agreements is at fair value, which is determined based on current forward interest rates as of the balance sheet date and are classified within Level 2. The cross-currency swap derivative contracts are used to partially hedge the Company’s net investments in foreign operations against adverse movements in exchange rates between the U.S. dollar and the Euro, the U.S. dollar and CNH (CNH is the Chinese Yuan traded in the offshore market) and the U.S. dollar and the Canadian dollar (CAD). The carrying value of the cross-currency swap derivative contracts is at fair value, which is determined based on the income approach with the relevant interest rates and foreign currency current exchange rates and forward curves as inputs as of the balance sheet date and are classified within Level 2. For purposes of fair value disclosure above, derivative values are presented gross. Further discussion of gross versus net presentation of the Company's derivatives is within Note 8.

​

Contingent consideration obligations are recognized and measured at fair value at the acquisition date and thereafter until settlement or expiration. Contingent consideration is classified within Level 3 as the underlying fair value is determined using income-based valuation approaches appropriate for the terms and conditions of each respective contingent consideration. The consideration expected to be transferred is based on the Company’s expectations of various financial measures. The ultimate payment of contingent consideration could deviate from current estimates based on the actual results of these financial measures. Contingent consideration was not material to the Company’s consolidated financial statements.

​

The carrying values of accounts receivable, accounts payable, cash and cash equivalents, commercial paper and notes payable approximate fair value because of their short maturities and as such are classified within Level 1.

​

The fair value of long-term debt is based on quoted market prices for the same or similar debt instruments (classified as Level 2). The carrying amount, which includes adjustments related to the impact of interest rate swap agreements, premiums and discounts, and deferred debt issuance costs, and the estimated fair value of long-term debt, including current maturities, held by the Company were:

​

8. DERIVATIVES AND HEDGING TRANSACTIONS

​

The Company uses foreign currency forward contracts, interest rate swap agreements, cross-currency swap derivative contracts and foreign currency debt to manage risks associated with foreign currency exchange rates, interest rates and net investments in foreign operations. The Company does not hold derivative financial instruments of a speculative nature or for trading purposes. The Company records derivatives as assets and liabilities in the Consolidated Balance Sheets at fair value. Changes in fair value are recognized immediately in earnings unless the derivative qualifies and is designated as a hedge. Cash flows from derivatives are classified in the Consolidated Statements of Cash Flows in the same category as the cash flows from the items subject to designated hedge or undesignated (economic) hedge relationships. The Company evaluates hedge effectiveness at inception and on an ongoing basis. If a derivative is no longer expected to be effective, hedge accounting is discontinued.

​

The Company is exposed to credit risk in the event of nonperformance of counterparties for foreign currency forward exchange contracts and interest rate swap agreements. The Company monitors its exposure to credit risk by using credit approvals and credit limits and by selecting major global banks and financial institutions as counterparties. The Company does not anticipate nonperformance by any of these counterparties, and therefore, recording a valuation allowance against the Company’s derivative balance is not considered necessary.

​

Derivative Positions Summary

​

Certain of the Company’s derivative transactions are subject to master netting arrangements that allow the Company to net settle contracts with the same counterparties. These arrangements generally do not call for collateral and as of the applicable dates presented in the following table, no cash collateral had been received or pledged related to the underlying derivatives.

​

The respective net amounts are included in other current assets, other assets, other current liabilities and other liabilities on the Consolidated Balance Sheets.

Cash Flow Hedges

​

The Company utilizes foreign currency forward contracts to hedge the effect of foreign currency exchange rate fluctuations on forecasted foreign currency transactions, including inventory purchases and intercompany royalty, intercompany loans, management fee and other payments. These forward contracts are designated as cash flow hedges. The changes in fair value of these contracts are recorded in accumulated other comprehensive income (loss) (“AOCI”) until the hedged items affect earnings, at which time the gain or loss is reclassified into the same line item in the Consolidated Statements of Income as the underlying exposure being hedged. Cash flow hedged transactions impacting AOCI are forecasted to occur within the next year. For forward contracts designated as hedges of foreign currency exchange rate risk associated with forecasted foreign currency transactions, the Company excludes the changes in fair value attributable to time value from the assessment of hedge effectiveness. The initial value of the excluded component (i.e., the forward points) is amortized on a straight-line basis over the life of the hedging instrument and recognized in the same line item in the Consolidated Statements of Income as the underlying exposure being hedged for intercompany loans. For all other cash flow hedge types, the forward points are mark-to-market monthly and recognized in the same line item in the Consolidated Statements of Income as the underlying exposure being hedged. The difference between fair value changes of the excluded component and the amount amortized in the Consolidated Statements of Income is recorded in AOCI.

​

Fair Value Hedges

​

The Company manages interest expense using a mix of fixed and floating rate debt. To help manage exposure to interest rate movements and to reduce borrowing costs, the Company may enter into interest rate swaps under which the Company agrees to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed upon notional principal amount. The mark-to-market of these fair value hedges is recorded as gains or losses in interest (income) expense and is offset by the gain or loss of the underlying debt instrument, which also is recorded in interest (income) expense. These fair value hedges are highly effective and thus, there is no impact on earnings due to hedge ineffectiveness.

​

In aggregate, the Company has entered into a series of interest rate swap agreements to convert $1.5 billion of its debt from a fixed interest rate to a floating interest rate. The fixed interest rates range from 1.3% to 4.8% and mature between 2026 and 2031. These interest rate swap agreements are designated as fair value hedges.

Net Investment Hedges

​

Euronotes

​

In April 2025 and June 2025, the Company elected to de-designate as a net investment hedge €300 million and €236 million, respectively, of its ten year 2015 senior notes maturing July 2025 (“Euronotes”). The Company designated its remaining outstanding €39 million Euronotes and related accrued interest as a hedge of its Euro denominated exposures from its investments in certain of its Euro denominated functional currency subsidiaries as of June 30, 2025. In July 2025 upon repayment of the €575 million ($674 million) on the Euronotes, the Company settled the remaining €39 million net investment hedge related to the Euronotes.

​

Cross-currency swap derivative contracts

​

In the second quarter of 2025, the Company entered into Euro cross-currency swap derivative contracts with an aggregate notional amount of €400 million, and Chinese Yuan cross-currency swap derivative contracts with an aggregate notional amount of CNH 1,080 million. In aggregate, the Company maintains Euro (“€”), Chinese Yuan (“CNH”), and Canadian dollar (“CAD”) cross-currency swap derivative contracts that are designated as net investment hedges of the Company’s related foreign currency denominated exposures from the Company’s investments in certain subsidiaries denominated in such functional currencies. As of June 30, 2025, the Company had €2,275 million ($2,581 million), CNH 4,699 million ($657 million), and CAD 280 million ($206 million) cross-currency swap derivative contracts outstanding as a hedge of the Company’s net investment in foreign operations.

​

The cross-currency swap derivative contracts exchange fixed-rate payments in one currency for fixed-rate payments in another currency. The changes in the spot rate of these instruments are recorded in AOCI in stockholders’ equity, partially offsetting the foreign currency translation adjustment of the Company’s related net investment that is also recorded in AOCI. Amounts excluded from the assessment of effectiveness are recognized in interest expense on a straight-line basis over the term of the hedge. The interest income or expense from these swaps are recorded in interest expense on the accompanying Consolidated Statements of Income consistent with the classification of interest expense attributable to the underlying debt.

​

The revaluation gains and losses on the Euronotes and cross-currency swap derivative contracts, which are designated and effective as hedges of the Company’s net investments, have been included as a component of the cumulative translation adjustment account, and were as follows:

Derivatives Not Designated as Hedging Instruments

​

The Company also uses foreign currency forward contracts to offset its exposure to the change in value of certain foreign currency denominated assets and liabilities held at foreign subsidiaries, primarily receivables and payables, which are remeasured at the end of each period. Although the contracts are effective economic hedges, they are not designated as accounting hedges. Therefore, changes in the value of these derivatives are recognized immediately in earnings, thereby offsetting the current earnings effect of the related foreign currency denominated assets and liabilities.

​

Effect of all Derivative Instruments on Income

12. INCOME TAXES

​

The Company’s tax rate was 19.9% and 16.2% for the second quarter of 2025 and 2024, respectively, and 20.1% and 13.1% for the first six months of 2025 and 2024, respectively. The change in the Company’s tax rate for the second quarter and first six months of 2025 compared to the second quarter and first six months of 2024 was driven primarily by the impact of discrete tax items and special (gains) and charges. Further information related to special (gains) and charges is included in Note 2.

​

The Company recognized net tax benefits related to discrete tax items of $5.0 million and $5.5 million in the second quarter and first six months of 2025, respectively. This included a tax benefit of $2.6 million and $9.9 million in the second quarter and first six months of 2025, respectively, associated with share-based compensation excess tax benefits. The remaining net tax benefit of $2.4 million and net tax expense of $4.4 million in the second quarter and first six months of 2025, respectively, is from the filing of foreign tax returns, audit settlements, unrecognized tax benefits, and other changes in estimates.

​

The Company recognized net tax benefits related to discrete tax items of $10.3 million and $58.5 million in the second quarter and first six months of 2024, respectively. This included a tax benefit of $41.9 million in the first six months of 2024 associated with transferring certain intangible property between affiliates and $3.7 million and $12.3 million in the second quarter and first six months of 2024, respectively, associated with share-based compensation excess tax benefits. The remaining net benefit of $6.6 million and $4.3 million in the second quarter and first six months of 2024, respectively, was from other income tax adjustments including the impact of changes in tax laws, audit settlements, unrecognized tax benefits and other changes in estimates.

​

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing the impact of OBBBA on its consolidated financial statements.

​

The Organization for Economic Co-operation’s (“OECD”) global minimum tax regime (“Pillar Two”) is effective in certain countries where the Company operates. As such, an estimate of Pillar Two tax has been considered within the provision for income taxes. The Company continues to monitor these legislative developments, but based on information available does not anticipate material impacts to the 2025 financial statements.

14. REVENUES

​

Revenue Recognition

​

Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing service.

​

Product and Sold Equipment

​

Product revenue is generated from sales of cleaning, sanitizing, water treatment, process treatment and colloidal silica products. In addition, the Company sells equipment which may be used in combination with its specialized products. Revenue from product and sold equipment is recognized when obligations under the terms of a contract with the customer are satisfied, which generally occurs with the transfer of the product or delivery of the equipment.

​

Service and Lease Equipment

​

Service and lease equipment revenue is generated from providing services or leasing equipment to customers. Service offerings include installing or repairing certain types of equipment, activities that supplement or replace headcount at the customer location, or fulfilling deliverables included in the contract. Global Water segment services are associated with water treatment and paper process applications. Global Institutional & Specialty segment services include cleaning and sanitizing programs and wash process solutions. Global Life Sciences segment services include pharmaceutical, personal care, infection and containment control solutions. Revenues included in Global Pest Elimination primarily relate to services designed to detect, eliminate and prevent pests. Revenue from service and leased equipment is recognized when the services are provided, or the customer receives the benefit from the leased equipment, which is over time. Service revenue is recognized over time utilizing an input method and aligns with when the services are provided. Typically, revenue is recognized using costs incurred to date because the effort provided by the field selling and service organization represents services provided, which corresponds with the transfer of control. Revenue for leased equipment is accounted for under Topic 842 Leases and recognized on a straight-line basis over the length of the lease contract.

​

Other Considerations

​

Contracts with customers may include multiple performance obligations. For contracts with multiple performance obligations, the consideration is allocated between products and services based on their stand-alone selling prices. Stand-alone selling prices are generally based on the prices charged to customers when the good or service is not bundled with other product or services or using an expected cost plus margin. Judgment is used in determining the amount of service that is embedded within the Company’s contracts, which is based on the amount of time spent on the performance obligation activities. The level of effort, including the estimated margin that would be charged, is used to determine the amount of service revenue. Depending on the terms of the contract, the Company defers the recognition of revenue when a future performance obligation has not yet occurred.

​

Taxes assessed by a governmental authority that are both imposed on, and concurrent with, a specific revenue-producing transaction, which are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight are recognized in cost of sales when control over the product has transferred to the customer.

​

Other estimates used in recognizing revenue include variable consideration related to customer programs and incentive offerings, including pricing arrangements, promotions and other volume-based incentives at the time the sale is recorded. These estimates are non-complex in nature and are based primarily on historical experience and anticipated performance over the contract period. In addition, timely sales data is available, limiting estimation uncertainty. Based on the certainty in estimating these amounts, they are included in the transaction price of the contracts and the associated remaining performance obligations.

​

The Company recognizes revenue when collection of the consideration expected to be received in exchange for transferring goods or providing services is probable.

​

The Company’s revenue policies do not provide for general rights of return. Estimates used in recognizing revenue include the delay between the time that products are shipped and when they are received by customers, when title transfers and the amount of credit memos issued in subsequent periods. Depending on market conditions, the Company may increase customer incentive offerings, which could reduce gross profit margins over the term of the incentive.

Net sales by geographic region were determined based on sales destination. The United States made up 54% and 53% of total revenues during the six months ended June 30, 2025 and 2024, respectively.

​

Accounts Receivable and Allowance for Expected Credit Losses

​

Accounts receivable are carried at the invoiced amounts, less an allowance for expected credit losses, and generally do not bear interest. The Company’s allowance for expected credit losses estimates the amount of expected future credit losses by analyzing accounts receivable balances by age and applying historical write-off and collection experience. The Company’s estimates separately consider macroeconomic trends, specific circumstances and credit conditions of customer receivables. Account balances are written off against the allowance when it is determined the receivable will not be recovered.

​

The Company’s allowance for expected return of products shipped and credits related to pricing or quantities shipped was $48.0 million and $52.5 million as of June 30, 2025 and December 31, 2024, respectively. Returns and credit activity are recorded directly as a reduction to revenue.

The following table summarizes the activity in the allowance for expected credit losses:

Contract Liability

​

Payments received from customers are based on invoices or billing schedules as established in contracts with customers. Accounts receivable are recorded when the right to consideration becomes unconditional. The contract liability relates to billings in advance of performance (primarily service obligations) under the contract. Contract liabilities are recognized as revenue when the performance obligation has been performed, which primarily occurs during the subsequent quarter.

​

15. OPERATING SEGMENTS

​

The Company’s organizational structure consists of global business units and market-based leadership teams. The Company’s seven 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 (“CODM”) at the identified operating segment level.

​

The Company’s operating segments that share similar economic characteristics and future prospects, nature of the products and production processes, end-use markets, channels of distribution and regulatory environment have been aggregated into four reportable segments: Global Water, Global Institutional & Specialty, Global Pest Elimination and Global Life Sciences.

​

Comparability of Reportable Segments

​

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. The Company made other immaterial changes, including the movement of certain customers and cost allocations between reportable segments. These changes are presented in "Other" columns of the table below. Prior period amounts have been recast to conform with current period presentation.

​

The Company evaluates the performance of its non-U.S. dollar functional currency international operations based on fixed currency exchange rates, which eliminates the impact of exchange rate fluctuations on its 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” column shown in the following table reflects international operations at fixed currency exchange rates established by management at the beginning of 2025, rather than the 2024 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” row in the following table.

​

​

The impact of the preceding changes on previously reported full year 2024 reportable segment information is summarized as follows:

The profitability of the Company’s operating segments is evaluated by management based on operating income.

​

Consistent with the Company’s internal management reporting, Corporate includes intangible asset amortization specifically from the Nalco and Purolite acquisitions and special (gains) and charges, as discussed in Note 2, that are not allocated to the Company’s reportable segments.

​

The Company has an integrated supply chain function that serves all of its reportable segments. As such, asset and capital expenditure information by reportable segment has not been provided and is not available, since the Company does not produce or utilize such information internally. In addition, although depreciation and amortization expense is a component of each reportable segment’s operating results, it is not discretely identifiable.

COMMITMENTS AND CONTINGENCIES
 6 Months Ended
Jun. 30, 2025
COMMITMENTS AND CONTINGENCIES  
COMMITMENTS AND CONTINGENCIES

16. COMMITMENTS AND CONTINGENCIES

​

The Company is subject to various claims and contingencies related to, among other things, workers’ compensation, general liability (including product liability), automobile claims, health care claims, environmental matters and lawsuits. The Company is also subject to various claims and contingencies related to income taxes. The Company also has contractual obligations including lease commitments.

​

The Company records liabilities when a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that a material loss may have been incurred.

​

Insurance

​

Globally, the Company has insurance policies with varying deductible levels for property and casualty losses. The Company is insured for losses in excess of these deductibles, subject to policy terms and conditions and has recorded both a liability and an offsetting receivable for amounts in excess of these deductibles. The Company is self-insured for health care claims for eligible participating employees, subject to certain deductibles and limitations. The Company determines its liabilities for claims on an actuarial basis.

​

Litigation and Environmental Matters

​

The Company and certain subsidiaries are party to various lawsuits, claims and environmental actions that have arisen in the ordinary course of business. These include from time to time antitrust, employment, commercial, patent infringement, tort, product liability and wage hour lawsuits, as well as possible obligations to investigate and mitigate the effects on the environment of the disposal or release of certain chemical substances at various sites, such as Superfund sites and other operating or closed facilities. The Company has established accruals for certain lawsuits, claims and environmental matters. The Company currently believes that there is not a reasonably possible risk of material loss in excess of the amounts accrued related to these legal matters. Because litigation is inherently uncertain, and unfavorable rulings or developments could occur, there can be no certainty that the Company may not ultimately incur charges in excess of recorded liabilities. A future adverse ruling, settlement or unfavorable development could result in future charges that could have a material adverse effect on the Company’s results of operations or cash flows in the period in which they are recorded.

​

The Company currently believes that such future charges related to suits and legal claims, if any, would not have a material adverse effect on the Company’s consolidated financial position.

​

TPC Group Litigation

​

On November 27, 2019, a Butadiene production plant owned and operated by TPC Group, Inc. in Port Neches, Texas, experienced an explosion and fire that resulted in personal injuries, the release of chemical fumes and extensive property damage to the plant and surrounding areas in and near Port Neches, Texas.

​

Nalco Company LLC, a subsidiary of Ecolab, supplied process chemicals to TPC used in TPC’s production processes. Nalco did not operate, manage, maintain or control any aspect of TPC’s plant operations.

​

In connection with its provision of process chemicals to TPC, Nalco was named in numerous lawsuits stemming from the plant explosion. Nalco has been named a defendant, along with TPC and other defendants, in multi-district litigation (“MDL”) proceedings pending in Orange County, Texas, alleging among other things claims for personal injury, property damage and business losses (In re TPC Group Litigation – A2020-0236-MDL, Orange County, Texas). Numerous other lawsuits were filed against Nalco, including TPC Group v. Nalco, E0208239, Jefferson County, Texas, a subrogation claim by TPC’s insurers seeking reimbursement for property damage losses. Over 5,000 plaintiffs (including the subrogation matter) asserted claims against Nalco. All claims have been consolidated for pretrial purposes into the MDL.

​

All of these cases make similar allegations and seek damages for personal injury, property damage, business losses and other damages, including exemplary damages.

​

On June 1, 2022, TPC and seven of its affiliated companies filed for bankruptcy under Chapter 11 (Case No. 22-10493-CTG, United States Bankruptcy Court for the District of Delaware). In connection with the bankruptcy cases, TPC disclosed an estimated range of its liability related to the Port Neches incident to individuals and homeowners (including subrogation claims) of approximately $152 million to $520 million. As part of their bankruptcy plan, TPC and its affiliates announced a settlement which allows the MDL plaintiffs a $500 million claim solely for purposes of claim allowance in the chapter 11 case and distribution of value pursuant to TPC’s bankruptcy plan. Other key terms of the settlement between TPC and the MDL plaintiffs include the establishment of a settlement trust for the benefit of certain general unsecured creditors, which is funded with $30 million and the assignment of TPC’s claims and causes of action, if any, against certain third parties, including Nalco, related to the TPC plant explosion. As part of the bankruptcy process, TPC and its debtor affiliates received a discharge of all MDL related claims, as did certain non-debtor affiliates to the extent third parties did not opt out of the non-debtor releases. As a result, TPC is no longer a defendant in the MDL. Nalco opted out of these releases, preserving any direct causes of action it may have against non-debtors. Furthermore, the allowance of the $500 million claim should have no effect on any claims or defenses asserted against or by Nalco in the MDL litigation. On December 1, 2022, the bankruptcy court confirmed the TPC bankruptcy plan, including the approval of the settlement and establishment of the aforementioned settlement trust. On December 16, 2022, the TPC bankruptcy plan went effective. As a result of the bankruptcy, the MDL was stayed. The stay was lifted in the fourth quarter of 2023 and various activities advancing discovery have resumed.

​

In July 2025, Nalco executed a settlement with a portion of the plaintiffs in the MDL. The Company continues to believe the claims asserted against Nalco are without merit and intends to defend the remaining claims vigorously. The Company also believes any potential loss should be covered by insurance subject to deductibles. However, the Company cannot predict the outcome of these lawsuits, the involvement the Company might have in these matters in the future or the potential for future litigation. Due to the large number of remaining plaintiffs and the fact that many of the claims do not specify an amount of supported damages, any estimate of any further loss or range of losses cannot be made at this time.

​

Vehicle Accident Litigation

​

In June 2024, an Ecolab employee was driving a company vehicle when it collided with another vehicle, resulting in fatalities and serious injuries. The Company was recently named in a lawsuit arising out of the collision in which the plaintiffs seek monetary damages. The Company believes any potential loss should be covered by insurance subject to its deductible. Due to the early stage of the litigation, an estimate of any loss or range of losses cannot be made at this time.

​

Environmental Matters

​

The Company is currently participating in environmental assessments and remediation at approximately 25 locations, the majority of which are in the U.S., and environmental liabilities have been accrued reflecting management’s best estimate of future costs. Potential insurance reimbursements are not anticipated in the Company’s accruals for environmental liabilities.

ASU 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

​

November 2023

​

The amendments in this ASU are to improve the disclosures about reportable segments and add more detailed information about a reportable segment’s expenses. The amendments in the ASU require public entities to disclose on an annual and interim basis significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss, other segment items by reportable segment, the title and position of the CODM, and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. The ASU does not change the definition of a segment, the method for determining segments, the criteria for aggregating operating segments into reportable segments, or the current specifically enumerated segment expenses that are required to be disclosed.

​

January 1, 2024

​

The Company adopted the standard and applied the amendments retrospectively to all periods presented. Adoption of this standard impacted the disclosures within the financial statements, but did not have an impact on the Company's financial position or the results of operations.

ASU 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

​

November 2023

​

The amendments in this ASU are to improve the disclosures about reportable segments and add more detailed information about a reportable segment’s expenses. The amendments in the ASU require public entities to disclose on an annual and interim basis significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss, other segment items by reportable segment, the title and position of the CODM, and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. The ASU does not change the definition of a segment, the method for determining segments, the criteria for aggregating operating segments into reportable segments, or the current specifically enumerated segment expenses that are required to be disclosed.

​

January 1, 2024

​

The Company adopted the standard and applied the amendments retrospectively to all periods presented. Adoption of this standard impacted the disclosures within the financial statements, but did not have an impact on the Company's financial position or the results of operations.

ASU 2024-03 and ASU 2025-01 Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses

​

November 2024 and January 2025

​

The amendments in this ASU are intended to improve expense disclosures, primarily by requiring disclosure of disaggregated information about certain income statement expense line items on an annual and interim basis.

​

Effective for annual reporting periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted.

​

The updates required by this standard should be applied prospectively, but retrospective application is permitted. The Company is currently evaluating the impact of adoption and additional disclosure requirements.
