Additionally, macroeconomic and geopolitical developments, including public health crises, escalating global conflicts, supply chain disruptions, labor market constraints, rising rates of inflation and high interest rates may amplify many of the risks discussed below to which we are subject. The extent of the impact of macroeconomic and geopolitical developments, including public health crises, on our financial and operating performance depends significantly on the duration and severity of such macroeconomic and geopolitical developments, the actions taken to contain or mitigate its impact and any changes in consumer behaviors as a result thereof.

Previous wording

Over the past year, global interest rates aimed at curbing inflation, as well as implications of geopolitical situations in Europe, the Middle East and China, have resulted in economic and demand uncertainty. Previously, the COVID pandemic, geopolitical instability and other global events have resulted in supply chain challenges, inflation, high interest rates, foreign currency exchange volatility, and volatility in global capital markets, which have affected our business and could have a material adverse impact on our business in the future. Countries such as Argentina and Turkey have experienced economic upheaval and similar upheaval in other countries with Ecolab operations could have a material adverse impact on our consolidated results of operations, financial position and cash flows by negatively impacting economic activity, including in our key end-markets, and by further weakening the local currency versus the U.S. dollar, resulting in reduced sales and earnings from our foreign operations, which are generated in the local currency, and then translated to U.S. dollars.

Previous wording

Additionally, changes in international trade policies by governments around the world, including the imposition or continuation of tariffs, could materially and adversely affect our business. In 2018, the U.S. imposed tariffs on certain imports from China and other countries, resulting in retaliatory tariffs by China and other countries. In February 2025, the U.S. proposed a 25% additional tariff on imports from Canada and Mexico and a 10% additional tariff on imports from China. These tariffs, any new tariffs or policies imposed by governments around the world, or any resulting retaliatory measures, to the extent implemented, could increase our costs, reduce our sales and earnings or otherwise have an adverse effect on our operations.

Current wording

Additionally, changes in international trade policies by governments around the world, including the imposition or continuation of tariffs, could materially and adversely affect our business. During 2025, new tariffs were imposed in the U.S. for imports from a broad range of countries and materials. Several countries also implemented or proposed retaliatory tariffs on imports from the U.S., as well as other barriers to trade. Ongoing changes in U.S. trade policy through administrative action or litigation create a heightened level of uncertainty for our business. These tariffs, any new tariffs or policies imposed by governments around the world, or any resulting retaliatory measures, to the extent implemented, could increase our costs, reduce our sales and earnings or otherwise have an adverse effect on ouroperations.

We rely to a large extent upon information technology systems and infrastructure to operate our business. The size and complexity of our information technology systems and those of strategic vendors make them vulnerable to failure, malicious intrusion and random attack. Acquisitions have resulted in further de-centralization of systems and additional complexity in our systems infrastructure. Likewise, data security breaches by employees or others with permitted access to our systems or to the systems of strategic vendors pose a risk that sensitive data may be exposed to unauthorized persons or to the public. Geopolitical tensions or conflicts, such as Russia’s invasion of Ukraine, may further heighten the risk of cybersecurity attacks. While we have continually matured our security program and capabilities and have had no material incidents to date, cyber threats continue to evolve and there can be no assurance that our efforts will prevent cybersecurity attacks or breaches in our systems or in the systems of strategic vendors, including cloud providers, that could cause reputational damage, business disruption or legal and regulatory costs; could result in third-party claims; could result in compromise or misappropriation of our intellectual property, trade secrets or sensitive information; or could otherwise materially adversely affect our business, including our business strategy, results of operations, or financial condition. Certain of our customer offerings include digital components, such as remote monitoring of certain customer operations. A breach of those remote monitoring systems could expose customer data giving rise to potential third-party claims and reputational damage. There may be other related challenges and risks as we complete implementation of our ERP system upgrade.

While we have continually matured our security program and capabilities and have had no material incidents to date, cyber threats continue to evolve, such as with the use of artificial intelligence, resulting in sophisticated new attack methods that are increasingly automated, targeted, and difficult to defend against, and there can be no assurance that our efforts will prevent cybersecurity attacks or breaches in our systems or in the systems of strategic vendors, including cloud providers, that could cause reputational damage, business disruption or legal and regulatory costs; could result in third-party claims; could result in compromise or misappropriation of our intellectual property, trade secrets or sensitive information; or could otherwise materially adversely affect our business, including our business strategy, results of operations, or financial condition. Certain of our customer offerings include digital components, such as remote monitoring of certain customer operations. A breach of those remote monitoring systems could expose customer data giving rise to potential third-party claims and reputational damage. Additionally, it may take considerable time for us to investigate and evaluate the full impact of cyber-attacks, particularly for sophisticated attacks, which may inhibit our ability to provide prompt, full, and reliable information about cybersecurity incidents to our customers, regulators, and the public. There may also be other related challenges and risks as we complete implementation of our ERP system upgrade, and businesses which we have acquired, or may in the future acquire, may have information technology system vulnerabilities which could increase our risk of cybersecurity attacks. Although we maintain insurance, our insurance coverage may not be sufficient in type or amount to prevent or recover losses resulting from cybersecurity attacks.

We continue to execute key business initiatives as part of our ongoing efforts to improve our efficiency and returns. In particular, we are making supply chain investments to secure supply and add new capacity in our Life Sciences business. Additionally, we are continuing implementation of our ERP system upgrades, which are expected to continue in phases over the next several years. These upgrades, which include sales, supply chain and certain finance functions, are expected to improve the efficiency of certain financial and related transactional processes. These upgrades involve complex business process design and a failure of certain of these processes could result in business disruption. We are also undertaking restructuring programs including the One Ecolab initiative leveraging our digital technologies to realign the functional work done in many countries into global centers of excellence. This program is discussed along with other restructuring activities under Note 3 of this Form 10-K. If the projects in which we are investing or the initiatives which we are pursuing are not successfully executed, our consolidated results of operations, financial position or cash flows could materially and adversely be affected.

War (including acts of terrorism or hostilities), natural or manmade disasters, water shortages or severe weather conditions, including the effects of climate change, affecting the energy, foodservice, hospitality, travel, health care, food processing, pulp and paper, mining, steel and other industries can cause a downturn in the business of our customers, which in turn can have a material adverse effect on our consolidated results of operations, financial position or cash flows. In particular, the U.S. Gulf Coast is a region with significant refining, petrochemicals and chemicals operations which provide us raw materials, as well as being an important customer base for our Water operating segment. Hurricanes or other severe weather events impacting the Gulf Coast, such as the winter freeze in Texas and the Gulf Coast in February 2021, can materially and adversely affect our ability to obtain raw materials at reasonable cost, or at all, and could adversely affect our business with our customers in the region.

Our business may face increased scrutiny from the investment community, other stakeholders, regulators, and the media related to our sustainability activities, including our commitments, goals, targets, and objectives, and our methodologies and timelines for pursuing them. If our sustainability practices do not meet the rapidly evolving, varied and often times conflicting investor or other stakeholder expectations and standards, our reputation, our ability to attract or retain employees, and our attractiveness as an investment, business partner, or as an acquiror could be negatively impacted. Similarly, our failure or perceived failure to pursue or fulfill our commitments, goals, targets, and objectives, to comply with ethical, environmental, or other standards, regulations, or expectations, or to satisfy reporting standards with respect to these matters, within the timelines we announce, or at all, could have operational, reputational, financial and legal impacts.

We are subject to income and other taxes in the United States and foreign jurisdictions, and our operations, plans and results are affected by tax and other initiatives around the world. We are also impacted by actions taken to tax-related matters by associations such as the Organization for Economic Co-operation and Development (“OECD”), which represents a coalition of member countries, and the European Commission which influence tax policies in countries where we operate. In particular, the OECD has coordinated negotiations among more than 140 jurisdictions with the goal of achieving consensus on various substantial changes to the international tax framework, including a 15% global minimum taxation regime (“Pillar Two”). Pillar Two took effect in several jurisdictions in which we operate starting in 2024 and will increase the burden and costs of our tax compliance. We continue to monitor these legislative developments, which based on information available, have not had material impacts to the 2024 financial statements. In addition, we are impacted by settlements of pending or any future adjustments proposed by the IRS or other taxing authorities in connection with our tax audits, all of which will depend on their timing, nature and scope. Increases in income tax rates, changes in income tax laws or unfavorable resolution of tax matters could have a material adverse impact on our financial results.

Pillar Two took effect in several jurisdictions in which we operate starting in 2024 and will increase the burden and costs of our tax compliance. The enactment of the One Big Beautiful Bill Act (“OBBBA”) in the U.S. introduced changes to U.S. international tax provisions. These changes may interact with Pillar Two in complex ways. Statements by the Group of Seven Nations (“G7”) suggest a potential “side-by-side” framework that could exempt certain U.S. parented groups from all or certain aspects of Pillar Two rules but the final outcome remains uncertain. The evolving nature of these reforms may impact our tax profile, increase compliance costs, and create additional risks of double taxation or inconsistent treatment across jurisdictions. We continue to monitor Pillar Two legislative developments, which, based on information available, have not had material impacts on the 2025 financial statements. In addition, we are impacted by settlements of pending or any future adjustments proposed by the IRS or other taxing authorities in connection with our tax audits, all of which will depend on their timing, nature and scope.

Current wording

We incur significant expenses related to the amortization of intangible assets and may be required to report losses resulting from the impairment of goodwill or other assets recorded in connection with the Nalco, Purolite and Ovivo Electronics transactions and other acquisitions.

Previous wording

We expect to continue to complete selected acquisitions and joint venture transactions in the future. In connection with acquisition and joint venture transactions, applicable accounting rules generally require the tangible and intangible assets of the acquired business to be recorded on the balance sheet of the acquiring company at their fair values. Intangible assets other than goodwill are required to be amortized over their estimated useful lives and this expense may be significant. Any excess in the purchase price paid by the acquiring company over the fair value of tangible and intangible assets of the acquired business is recorded as goodwill. If it is later determined that the anticipated future cash flows from the acquired business may be less than the carrying values of the assets and goodwill of the acquired business, the assets or goodwill may be deemed to be impaired. In this case, the acquiring company may be required under applicable accounting rules to write down the value of the assets or goodwill on its balance sheet to reflect the extent of the impairment. This write-down of assets or goodwill is generally recognized as a non-cash expense in the statement of operations of the acquiring company for the accounting period during which the write down occurs. As of December 31, 2024, we had goodwill of $7.9 billion which is maintained in various reporting units, including goodwill from the Nalco and Purolite transactions. If we determine that any of the assets or goodwill recorded in connection with the Nalco and Purolite transactions or any other prior or future acquisitions or joint venture transactions have become impaired, we will be required to record a loss resulting from the impairment. Impairment losses could be significant and could have a material adverse effect on our consolidated results of operations and financial position.
