Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

​

The following management discussion and analysis (“MD&A”) provides information we believe is useful in understanding our operating results, cash flows and financial condition. We provide quantitative information about the material sales drivers including the impact of changes in volume and pricing and the effect of acquisitions and changes in foreign currency at the corporate and reportable segment level. We also provide quantitative information regarding special (gains) and charges, discrete tax items and other significant factors we believe are useful for understanding our results. Such quantitative drivers are supported by comments meant to be qualitative in nature. Qualitative factors are generally ordered based on estimated significance.

​

The MD&A should be read in conjunction with both the unaudited consolidated financial information and related notes included in this Form 10-Q, and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2020. This discussion contains various Non-GAAP Financial Measures and also contains various Forward-Looking Statements within the meaning of the Private Securities Litigation Reform Act of 1995. We refer readers to the statements entitled “Non-GAAP Financial Measures” and “Forward-Looking Statements” located at the end of Part I of this report.

​

Comparability of Results

​

ChampionX Transaction

​

On June 3, 2020, we completed the separation of our Upstream Energy business (the “ChampionX business”) in a Reverse Morris Trust transaction (the “Transaction”) through the split-off of ChampionX Holding Inc. (“ChampionX”), formed by Ecolab as a wholly owned subsidiary to hold the ChampionX Business, followed immediately by the merger of ChampionX (the “Merger”) with a wholly owned subsidiary of ChampionX Corporation (f/k/a Apergy Corporation, “Apergy”).

​

The ChampionX business met the criteria to be reported as discontinued operations because the separation of ChampionX business was a strategic shift in business that had a major effect on our operations and financial results. Therefore, we reported the historical results of ChampionX, including the results of operations, cash flows, and related assets and liabilities, as discontinued operations. Unless otherwise noted, the accompanying MD&A has been revised to reflect the ChampionX business as discontinued operations and all prior year balances have been revised accordingly to reflect continuing operations only.

​

Fixed Currency Foreign Exchange Rates

​

Management evaluates the sales and operating income 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. Public currency rate data provided within the “Segment Performance” section of this MD&A reflect amounts translated at actual public average rates of exchange prevailing during the corresponding period and is provided for informational purposes only.

​

Impact of Acquisitions and Divestitures

​

Acquisition adjusted growth rates exclude the results of our acquired businesses from the first twelve months post acquisition and exclude the results of our divested businesses from the twelve months prior to divestiture. In addition, as part of the separation, we also entered into a Master Cross Supply and Product Transfer agreement with ChampionX to provide, receive or transfer certain products for a period up to 36 months. Sales of product to ChampionX under this agreement are recorded in product and equipment sales in the Corporate segment along with the related cost of sales. These transactions are removed from the consolidated results as part of the calculation of the impact of acquisitions and divestitures.

​

OVERVIEW OF THE THIRD QUARTER ENDED SEPTEMBER 30, 2021

​

Sales Performance

​

When comparing third quarter 2021 against third quarter 2020, sales performance was as follows:

​

●Reported net sales increased 10% to $3,321 million, fixed currency sales increased 8% and acquisition adjusted fixed currency sales increased 8%.
●Fixed currency sales for our Global Industrial segment increased 7% to $1,620 million. Acquisition adjusted fixed currency sales increased 7%, as strong growth in Water and Paper, led by recovering market conditions and new business wins, along with a good gain in Food & Beverage and modest Downstream sales growth, yielded the increase.
●Fixed currency sales for our Global Institutional & Specialty segment increased 18% to $1,077 million and acquisition adjusted fixed currency sales increased 17%. Strong growth in the Institutional operating segment reflected recovering markets in the U.S. and Europe, driven by new business wins including gains from Ecolab Science Certified programs, innovation and pricing. Specialty sales increased modestly as strong quick service sales more than offset lower food retail sales.
●Fixed currency sales for our Global Healthcare & Life Sciences segment decreased 13% to $290 million. Acquisition adjusted fixed currency sales decreased 17% compared to a 29% increase last year when sales benefited from strong COVID-19 related demand. Underlying Healthcare sales are estimated to be growing at mid-single digit rates and Life Sciences’ sales are estimated to be growing at low double-digit rates, both driven by new business wins and increased hygiene awareness.
●Fixed currency sales and acquisition adjusted fixed currency sales for Other increased 13% to $326 million led by strong growth in Pest Elimination as it benefited from new business wins and recovering markets.

​

Financial Performance

​

When comparing third quarter 2021 against third quarter 2020, our financial performance was as follows:

​

●Reported operating income increased 13% to $466 million. Excluding the impact of special (gains) and charges from both 2021 and 2020 reported results, adjusted operating income increased 15% and our adjusted fixed currency operating income increased 13%.
●Net income from continuing operations attributable to Ecolab increased 32% to $324 million. Excluding the impact of special (gains) and charges and discrete tax items from both 2021 and 2020 reported results, our adjusted net income from continuing operations attributable to Ecolab increased 20%.
●Reported diluted EPS from continuing operations of $1.12 increased 32%. Excluding the impact of special (gains) and charges and discrete tax items from both 2021 and 2020 reported results, adjusted diluted EPS from continuing operations increased 20% to $1.38 in the third quarter of 2021. In the third quarter of 2021, Hurricane Ida had an estimated negative impact on reported diluted EPS and adjusted diluted EPS of $0.03.
●Our reported tax rate was 18.3% during the third quarter of 2021, compared to 14.5% during the third quarter of 2020. Excluding the tax rate impact of special (gains) and charges and discrete tax items from both 2021 and 2020 results, our adjusted tax rate was 19.5% during the third quarter of 2021, compared to 20.0% during the third quarter of 2020.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

​

We use foreign currency forward contracts, interest rate swap agreements and foreign currency debt to manage risks associated with foreign currency exchange rates, interest rates and net investments in our foreign operations. We do not hold derivative financial instruments of a speculative nature or for trading purposes. For a more detailed discussion of derivative instruments, refer to Note 9, entitled “Derivatives and Hedging Transactions”, of the consolidated financial statements located under Part I, Item 1 of this quarterly report on Form 10-Q.

​

​

​

​

​

Item 4. Controls and Procedures

​

As of September 30, 2021, we carried out an evaluation, under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation, our President and Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures are effective.

​

During the period July 1, 2021 through September 30, 2021, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

​

We are continuing our implementation of our enterprise resource planning (“ERP”) system upgrades, which are expected to occur in phases over the next several years. These upgrades, which include supply chain and certain finance functions, are expected to improve the efficiency of certain financial and related transactional processes. These upgrades of the ERP systems will affect the processes that constitute our internal control over financial reporting and will require testing for effectiveness.

Item 1. Legal Proceedings

​

Note 17, entitled “Commitments and Contingencies” located under Part I, Item 1 of this Form 10-Q is incorporated herein by reference.

​

​

Item 1A. Risk Factors

​

In our report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission on February 26, 2021, we identify under Item 1A important factors which could affect our financial performance and could cause our actual results for future periods to differ materially from our anticipated results or other expectations, including those expressed in any forward-looking statements made in this Form 10-Q. See the section entitled Forward-Looking Statements located on page 54 of this Form 10-Q. We may also refer to such disclosure to identify factors that may cause results to differ from those expressed in other forward-looking statements made in oral presentations, including telephone conferences and/or webcasts open to the public.

​

The discussion below provides updates and additions to the risk factors and should be read together with the full list of risk factors set forth in the Form 10-K.

​

The COVID-19 pandemic and measures taken in response thereto have materially and adversely impacted, and we expect may continue to materially and adversely impact, our business and results of operations, and the full impact of the pandemic will depend on future developments, which are highly uncertain and cannot be predicted.

​

Beginning in March 2020, the COVID-19 pandemic had a rapid and significant negative impact on the global economy, including a significant downturn in the foodservice, hospitality and travel industries. Measures taken to alleviate the pandemic (such as stay-at-home orders and other responsive measures) significantly impacted our restaurant and hospitality customers and negatively affected demand for our products and services in these segments, resulting in a material adverse effect on our business and results of operations. While many of these measures have eased in the U.S. through the third quarter driving increased consumer traffic and in-unit dining, restrictions on activities continue in many other regions, particularly those where vaccination rates lag, continuing to impact consumer activity in those regions. Concerns remain that our markets could see a prolonged resurgence of cases triggering additional government mandated lockdowns or similar restrictions, for example due to the emergence of new variants against which existing vaccines are not as effective or which may be more easily transmitted, particularly to those unvaccinated. In addition, the COVID-19 pandemic continues to have a material effect on the macroeconomic environment, and there is continued uncertainty around its duration and ultimate impact.

​

We expect the full impact of the COVID-19 pandemic, including the extent of its effect on our business, results of operations and financial condition, to be dictated by future developments which remain uncertain and cannot be predicted, such as the severity of the disease, the duration of the outbreak, the distribution, acceptance and efficacy of vaccines, the likelihood of a resurgence of the outbreak, including as a result of emerging variants, actions that may be taken by governmental authorities intended to minimize the spread of the pandemic or to stimulate the economy and other unintended consequences. In addition to the reduction in the demand for our products and services, the COVID-19 pandemic has had, and we expect will continue to have, certain negative impacts on our business, including, but not limited to, the following:

​

●We rely on a global workforce and take measures to protect the health and safety of our employees, customers and others with whom we do business while continuing to effectively manage our employees and maintain business operations. We have taken additional measures and incurred additional expenses to protect the health and safety of our employees to comply with applicable government requirements and safety guidance. Additionally, our business operations may be disrupted if a significant portion of our workforce is unable to work safely and effectively due to illness, quarantines, government actions or other restrictions or measures responsive to the pandemic, or if members of senior management or our Board of Directors are unable to perform their duties for an extended period of time. A significant outbreak in one of our manufacturing facilities could

​

adversely impact our ability to make and ship products in a timely manner. Measures taken across our business operations to address health and safety may not be sufficient to prevent the spread of COVID-19 among our employee base, customers and others. Therefore, we could face operational disruptions and incur additional expenses, including devoting additional resources to assisting employees diagnosed with COVID-19 and further changing health and safety protocols and processes, that could adversely affect our business and results of operations.

​

●A significant number of our employees, as well as customers and others with whom we do business, continue to work remotely in response to the COVID-19 pandemic. Our business operations may be disrupted, and we may experience increased risk of adverse effects to our business, if our business operations are negatively impacted as a result of remote work arrangements, including due to cybersecurity risks or other disruption to our technology infrastructure. Further, if our key operating facilities experience closures or worker shortages as a result of COVID-19, whether temporary or sustained, our business operations could be significantly disrupted.

​

●We are subject to the mandatory vaccination and workplace safety protocols of Executive Order 14042 issued on September 9, 2021 and subsequent guidance issued thereunder by the Safer Federal Workforce Task Force. This mandate applies broadly to require covered federal contractor employees on covered contracts, those who perform duties in connection with a covered contract, and those working at the same workplace as covered employees, to be fully vaccinated for COVID-19 by December 8, 2021, except for those that are legally entitled to an accommodation under applicable law. We may similarly be required to flow-down our obligations to certain of our subcontractors and suppliers. The guidance remains subject to the interpretation of various government agencies and other entities, and questions remain regarding the specific application of the Executive Order and related guidance. As a result, if our understanding of its application to our workforce differs from our federal customers’ interpretation, or many of our covered employees are unwilling to comply with the mandate, we may experience increased costs, business disruptions and attrition as a result of the mandate. Additionally, we may be subject to potential breach of contract claims, loss of business and assessment of fines if we or our affected subcontractors and suppliers are not able to fully comply in the time frame provided or if such subcontractors and suppliers choose to terminate their contract rather than comply.

​

●Cost management and various cost-containment actions implemented across our business in response to the COVID-19 pandemic could hinder execution of our business strategy, including the deferral of planned capital expenditures, and could adversely affect our business and results of operations.

​

●We believe that we appropriately reserve for expected credit losses, however we cannot be certain that loss or delay in the collection of accounts receivable will not have a material adverse effect on our results of operations and financial condition.

​

We are subject to information technology system failures, network disruptions and breaches in data security.

​

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 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 pose a risk that sensitive data may be exposed to unauthorized persons or to the public. While we have invested in protection of data and information technology, we have experienced immaterial cybersecurity attacks and incidents, and there can be no assurance that our efforts will prevent failures, cybersecurity attacks or breaches in our systems 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 adversely affect our business. 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.
