Ecolab Inc. (NYSE: ECL):

FOURTH QUARTER HIGHLIGHTS:

• Continued strong fourth quarter sales growth was partially offset by increased COVID-related effects on broad business activity and a near doubling of delivered product cost inflation (which includes raw materials and freight) and supply constraints compared to the third quarter.
• Reported sales from continuing operations +10% versus last year. Acquisition adjusted fixed currency sales +9%.
• Reported diluted EPS from continuing operations $1.04, flat versus last year.
• Adjusted diluted EPS from continuing operations, excluding special gains and charges, discrete tax items and the impact of the Purolite transaction, were $1.28, +4% versus last year.
• The earnings increase reflects accelerated pricing and volume growth, along with lower pension and interest expense, which were partially offset by substantially higher delivered product costs and the comparison to lower variable compensation last year.
• As previously disclosed, unfavorable delivered product costs and supply constraints resulted in an additional estimated unfavorable $0.10 per share in the fourth quarter versus our initial expectations.

The fourth quarter results reflected strong sales growth, driven by accelerated pricing and further robust new business wins in an uneven market recovery, that was partially offset by increased COVID-related effects on broad business activity and a near doubling of delivered product cost inflation and supply constraints compared to the third quarter.

CEO comment

Commenting on the quarter, Christophe Beck, Ecolab’s president and chief executive officer, said, “We are very pleased with the strong topline growth we delivered in the fourth quarter, led by double-digit gains in our Institutional and Specialty and Other segments and continued strong growth in our Industrial segment. Strong volume and pricing momentum was largely offset by significant raw materials and freight cost increases, which grew an estimated 20% year-on-year in the fourth quarter, leading to an estimated 10% overall impact on our total cost of sales, almost double the rate of increase we saw in the third quarter.

“I am proud of what our team accomplished in 2021 as our business fundamentals continued to improve in a very unique environment. We delivered record new business wins, continued to accelerate pricing to 4% as we exited the fourth quarter, launched a strong innovation pipeline, and further improved our productivity as we leveraged our digital investments. Together, these actions enabled us to mitigate an estimated $1.00 per share of substantial delivered product cost inflation and other supply constraints as we grew 2021 adjusted diluted earnings per share by 17%. Further, our recent acquisition of Purolite is progressing well and we are excited about the increased customer value and incremental growth opportunities this unique and high growth platform brings to Ecolab.

“We now move into 2022 with strong business momentum. With very healthy sales growth, robust new business wins, new innovation and increased pricing, we expect to progressively compensate for higher delivered product costs and to drive strong earnings growth. While we expect a decent global economy, we also expect the COVID impacts to remain significant during the first half of the year, and we expect inflation to remain high before it progressively eases during the second half of the year.

“We expect these cost impacts to remain especially strong in the first quarter of 2022, even slightly higher than those experienced in the fourth quarter. We look for the first quarter to show healthy

sales growth and a flattish year-over-year earnings per share comparison impacted by continued high raw material and freight costs. We also believe that our accelerating pricing and continued strong volume growth will progressively outpace higher expected delivered product costs over the following quarters. For the full year 2022, we believe our sales, pricing and cost efficiency actions will enable us to deliver continued strong sales gains with adjusted diluted earnings per share growth reaching low-teens levels, assuming once again that inflation and supply constraints ease as the year progresses.

“While the external environment remains dynamic, we are confident in our fundamental positioning and our proven ability to leverage our opportunities to improve our long-term margins further and to continue to deliver superior long-term results for our customers and shareholders.”

Fourth Quarter 2021 Consolidated Results

Ecolab’s fourth quarter reported and fixed currency sales increased 10% and acquisition adjusted fixed currency sales increased 9% when compared to the prior year.

Fourth quarter 2021 reported operating income decreased 7% and includes the impact of COVID-related special charges and the impact of the Purolite acquisition. Adjusted operating income and adjusted fixed currency operating income both decreased 1%. The operating income decrease reflects the accelerated pricing and volume growth which were offset by significantly higher delivered product costs and the comparison to lower variable compensation last year. As previously disclosed, unfavorable supply constraints resulted in an additional estimated unfavorable $0.10 per share in the fourth quarter versus our initial expectations.

Reported interest expense decreased 8% reflecting lower average debt levels and lower average interest rates from debt refinancing transactions, though this benefit was partially offset by new debt issued to fund the December 1, 2021 Purolite acquisition.

The reported income tax rate for the fourth quarter of 2021 was 12.6% compared with the reported rate of 19.3% in the fourth quarter of 2020. Excluding special gains and charges, discrete tax items and the impact of the Purolite transaction, the adjusted tax rate for the fourth quarter of 2021 was 17.3% compared with the adjusted tax rate of 18.3% in the fourth quarter of 2020. The lower tax rate in the fourth quarter of 2021 reflected tax planning benefits.

Fourth quarter 2021 reported net income from continuing operations attributable to Ecolab was flat versus the prior year. Excluding the impact of special gains and charges, discrete tax items and the impact of the Purolite transaction, adjusted net income from continuing operations attributable to Ecolab increased 4% versus the prior year.

Reported diluted earnings per share from continuing operations was flat versus the prior year. As expected, the impact of Purolite (excluding acquisition-related special charges) was $0.02 per share dilutive to reported earnings per share from continuing operations as strong sales growth since its December 1, 2021 acquisition was more than offset by acquisition-related amortization and interest expense. Adjusted diluted earnings per share from continuing operations increased 4% when compared against the fourth quarter 2020. Currency translation did not have a material impact on fourth quarter 2021 earnings per share.

Fourth Quarter 2021 Segment Review

Acquisition adjusted fixed currency sales increased 7%. Strong growth in Water, Paper and Downstream, led by new business wins and accelerated pricing, along with good gains in Food & Beverage, yielded the increase. Acquisition adjusted fixed currency operating income decreased 14% compared to a very strong 17% increase last year as accelerated pricing and higher volume were more than offset by significantly higher delivered product costs, unfavorable supply constraints, and the comparison to lower variable compensation last year.

Acquisition adjusted fixed currency sales increased 19%. Strong growth in the Institutional division reflected improved volume, further good new business wins, further gains from Ecolab Science Certified programs, new innovation and pricing despite a stalled recovery in restaurant and lodging activity versus the third quarter due to COVID-related impacts. Specialty sales increased modestly as strong quickservice sales more than offset lower food retail sales, in part due to customer staffing shortages. Acquisition adjusted fixed currency operating income increased 68% reflecting increased volume and accelerated pricing that more than offset higher delivered product costs and the comparison to lower variable compensation last year.

Acquisition adjusted fixed currency sales decreased 13% compared to a 22% increase last year when sales benefited from strong COVID-related demand. Acquisition adjusted fixed currency operating income decreased 33%, primarily reflecting the comparison to the very strong sales volume last year (when operating income grew 65%) as well as the impact of fourth quarter 2021’s unfavorable supply constraints; these were partially offset by favorable pricing and lower variable compensation.

The Other segment includes Pest Elimination, Textile Care and Colloidal Technologies

Acquisition adjusted fixed currency sales increased 13%. Growth was strong across all divisions. Acquisition adjusted fixed currency operating income decreased 1% as accelerated pricing and volume growth was more than offset by the comparison to lower variable compensation last year and higher delivered product costs.

Corporate

Fourth quarter of 2021 corporate segment includes:

• sales of $35 million to ChampionX under the Master Cross Supply and Product Transfer agreements we entered into as part of the ChampionX separation
• amortization expense of $31 million related to the Nalco merger intangible assets
• net special charges of $84 million that primarily reflected COVID-related charges and Purolite acquisition costs

Special gains and charges for the fourth quarter of 2020 were a net charge of $62 million and primarily include restructuring charges and COVID-related charges.

2022 Business Outlook

We move into 2022 with strong business momentum. With very healthy sales growth, robust new business wins, new innovation and increased pricing, we expect to progressively compensate for higher delivered product costs and to drive strong earnings growth. While we expect a decent global economy, we also expect the COVID impacts to remain significant during the first half of the year, and we expect inflation to remain high before it progressively eases during the second half of the year.

We expect these cost impacts to remain especially strong in the first quarter of 2022, even slightly higher than those experienced in the fourth quarter. We look for the first quarter to show healthy sales growth and a flattish year-over-year earnings per share comparison impacted by continued high raw material and freight costs.

For the full year 2022, we believe our sales, pricing and cost efficiency actions will enable us to deliver continued strong sales gains with adjusted diluted earnings per share growth reaching low-teens levels, assuming once again that inflation and supply constraints ease as the year progresses. We continue to expect the impact of Purolite, including $0.26 per share of transaction-related amortization, will be neutral to 2022 adjusted diluted earnings per share.

We remain confident in our long-term outlook as our value proposition to help solve the world’s people, planet and business health needs is more important than ever. With our strong pricing and an inflationary environment that will ease ultimately and lead to higher margins, we expect to continue to leverage our robust growth opportunities to drive superior results for our customers and shareholders.

Non-GAAP Financial Information

This news release and certain of the accompanying tables include financial measures that have not been calculated in accordance with accounting principles generally accepted in the U.S. (“GAAP”).

These non-GAAP financial measures (including with respect to continuing operations) include:

• fixed currency sales
• adjusted net sales
• adjusted fixed currency sales
• acquisition adjusted fixed currency sales
• adjusted cost of sales
• adjusted gross margin
• fixed currency operating income
• fixed currency operating income margin
• adjusted operating income
• adjusted fixed currency operating income
• adjusted fixed currency operating income margin
• acquisition adjusted fixed currency operating income
• acquisition adjusted fixed currency operating income margin
• adjusted other (income) expense
• adjusted interest expense
• adjusted tax rate
• adjusted net income attributable to Ecolab
• adjusted diluted earnings per share

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.

Our non-GAAP adjusted financial measures for net sales excludes Purolite net sales. Our non-GAAP adjusted financial measures for cost of sales, gross margin, operating income, other (income) expense and interest expense exclude the impact of special (gains) and charges and (with the exception of other (income) expense) the impact of the Purolite transaction, and our non-GAAP measures for tax rate, net income attributable to Ecolab and diluted earnings per share further exclude the impact of discrete tax items. We include items within special (gains) and charges and discrete tax items that we believe can significantly affect the period-over-period assessment of operating results and not necessarily reflect costs associated with historical trends and future results. After tax special (gains) and charges are derived by applying the applicable local jurisdictional tax rate to the corresponding pre-tax special (gains) and charges.

We evaluate the performance of our international operations based on fixed currency rates of foreign exchange, which eliminate the translation impact of exchange rate fluctuations on our international results. Fixed currency amounts included in this release are based on translation into U.S. dollars at the fixed foreign currency exchange rates established by management at the beginning of 2021. We also provide our segment results based on public currency rates for informational purposes.

Our reportable segments do not include the impact of intangible asset amortization from the Nalco merger or the impact of special (gains) and charges as these are not allocated to the Company’s reportable segments.

Acquisition adjusted growth rates exclude the results of any acquired business from the first twelve months post acquisition and exclude the results of divested businesses from the previous twelve months prior to divestiture. Acquisition adjusted growth rates also exclude sales to our Venezuelan deconsolidated subsidiaries from both the current period and comparable period of the prior year. 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.

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 this news release. Reconciliations of our non-GAAP measures are included in the following "Supplemental Non-GAAP Reconciliations" and “Supplemental Diluted Earnings per Share Information” tables included in this news release.

We do not provide reconciliations for non-GAAP estimates on a forward-looking basis (including those contained in this report) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of various items that have not yet occurred, are out of our control and/or cannot be reasonably predicted, and that would impact reported earnings per share and the reported tax rate, the most directly comparable forward-looking GAAP financial measures to adjusted earnings per share and the adjusted tax rate. For the same reasons, we are unable to address the probable significance of the unavailable information.

(ECL-E)

As shown in the “Fixed Currency Rates” tables above, we evaluate the performance of our international operations based on fixed currency exchange rates, which eliminate the impact of exchange rate fluctuations on our international operations. Amounts shown in the “Public Currency Rates” tables above reflect amounts translated at actual public average rates of exchange prevailing during the corresponding period, and are provided for informational purposes. The difference between the fixed currency exchange rates and the public currency exchange rates is reported as “Currency impact” in the “Fixed Currency Rates” tables above.

The Corporate segment includes amortization from the Nalco merger intangible assets. The Corporate segment also includes special (gains) and charges reported on the Consolidated Statement of Income.
