Ecolab Fourth Quarter Reported Diluted EPS $1.47; Adjusted Diluted EPS $1.66, +8% ; 2020 Adjusted Diluted EPS Forecast $6.33 to $6.53, +9% To 12%

Ecolab Inc. (NYSE: ECL):

FOURTH QUARTER HIGHLIGHTS:

• Reported diluted EPS $1.47, +9%.
• Adjusted diluted EPS $1.66, +8%, excluding special gains and charges and discrete tax items. Excluding the estimated impact of a European Healthcare product recall, adjusted diluted earnings per share would have been +10% to $1.69.
• Reported sales +2%. Acquisition adjusted fixed currency sales +1% as growth in the Industrial, Institutional and Other segments was partially offset by a 3% decline in Energy. Excluding the Upstream Energy business (recently renamed ChampionX), acquisition adjusted fixed currency sales were +3%.
• Reported operating margins -80 bps. Strong adjusted fixed currency operating margin expansion, +60 bps, led by double-digit Industrial and Energy segment income growth, as pricing, lower delivered product costs and cost efficiency actions more than offset investments in the business and the recall.

2020 FORECAST:

• Full year 2020 adjusted diluted EPS forecast (including ChampionX) $6.33 to $6.53, +9% to +12%, as improving new business growth, pricing and cost efficiencies are expected to more than offset investments in the business and an estimated unfavorable $0.05 per share from the coronavirus outbreak in the first quarter.

Results shown in this release are preliminary until our financial statements are filed in our 2019 Form 10-K. See the “Non-GAAP Financial Information” section of this release for further discussion regarding adjusted financial information. Unless otherwise stated, forecasts include ChampionX.

Better pricing, new business gains, product innovation and cost efficiencies more than offset investments in the business and the Healthcare product recall to yield an 8% increase in fourth quarter 2019 adjusted diluted earnings per share.

CEO comment

Commenting on the quarter, Douglas M. Baker, Jr., Ecolab’s chairman and chief executive officer said, “We accomplished a great deal in 2019 that we expect will benefit us going forward. We successfully completed a major North American ERP implementation, separated our Upstream Energy business (ChampionX) to facilitate a merger with Apergy Corporation, continued to build and develop both our management team and our global operations, expanded our sustainability commitments and performance, continued our digital investments and drove record new business results in the second half. We accomplished all this while delivering both a double-digit free cash flow increase and another year of double-digit adjusted earnings growth.

“Further, we delivered solid earnings growth in the fourth quarter while re-starting our volume momentum build. Margins continued to expand as expected reflecting the strong pricing and efficiency work over the last two years. This drove an 8% adjusted diluted earnings per share increase, which rose 10% when excluding the headwind from the Healthcare product recall. Importantly, the underlying metrics continue to improve, particularly business retention and business gains, and we expect this to continue and translate into sales acceleration as we move into 2020.

“As we look to 2020, we expect another strong earnings year despite a challenging environment. We have assumed a $0.05 impact in the first quarter for the coronavirus outbreak; we are not yet able to estimate and forecast the impact for the second quarter through fourth quarter. We also face an estimated $0.12 per share from pension and currency headwinds for the year. However, we have strong underlying new business momentum and our innovation pipeline is strong, including our multiple-year digital investments. Additionally, our North American ERP system work completed in 2019 enables us to more fully leverage our scale, driving further efficiencies. Therefore, we see our sales trends improving throughout the year, and coupled with continued margin expansion, driving another year of strong adjusted earnings growth. Importantly, we plan to continue our significant but high value investments in digital technology and product innovation, which along with our focus on talent, are key to our continued success long term.”

Fourth Quarter 2019 Consolidated Results

Ecolab's fourth quarter reported sales increased 2% and fixed currency sales increased 3%. Acquisition and divestiture adjusted fixed currency sales increased 1% when compared to the prior year. Excluding the ChampionX business, acquisition adjusted fixed currency sales increased 3%.

Fourth quarter 2019 reported operating income decreased 4% and fixed currency operating income decreased 3%; both include the impact of special charges, which primarily relate to our previously announced efficiency initiative and the planned separation of the ChampionX business. Adjusted fixed currency operating income increased 7%. Pricing, lower delivered product costs and cost efficiency initiatives more than offset investments in the business and the recall during the quarter.

Reported other income, which primarily consists of the return on pension assets and other non-service costs of our pension obligations, decreased 33%. Excluding special charges related to pension settlements and curtailments, adjusted other income increased 15%.

Reported interest expense decreased 14% in the quarter primarily reflecting higher interest income and lower outstanding debt.

The reported income tax rate for the fourth quarter of 2019 was 17.7% compared with the reported rate of 27.0% in the fourth quarter of 2018. Excluding special gains and charges and discrete tax items, the adjusted tax rate was 20.1% in the fourth quarter of 2019 compared with 19.9% for the same period last year.

Fourth quarter 2019 reported net income attributable to Ecolab increased 9%. Excluding the impact of special gains and charges and discrete tax items, adjusted net income attributable to Ecolab increased 8%.

Reported diluted earnings per share increased 9%. Adjusted diluted earnings per share rose 8% when compared against fourth quarter 2018. Currency translation had a $0.01 unfavorable impact on fourth quarter 2019 adjusted diluted earnings per share.

Ecolab reacquired approximately 30,000 shares of its common stock during the fourth quarter of 2019.

Acquisition adjusted fixed currency sales rose 4% led by good growth in Water, Food & Beverage and Life Sciences. Acquisition adjusted fixed currency operating income increased 13% reflecting improved pricing and lower delivered product costs.

Acquisition adjusted fixed currency sales grew 2% led by Specialty. Segment sales were impacted by previous low margin business exits that softened fourth quarter growth and a Healthcare product recall. Acquisition adjusted fixed currency operating income was flat as pricing and cost savings actions offset investments in the business and the impact of the Healthcare recall. Adjusted for the Healthcare product recall, acquisition adjusted fixed currency sales rose 3% and acquisition adjusted fixed currency operating income rose 3%.

Acquisition adjusted fixed currency sales decreased 3%. ChampionX sales were slightly lower as a significant decline in the well stimulation business (reflecting the reduced North American industry activity) was partially offset by good growth in production sales. Downstream sales rose modestly. Acquisition adjusted fixed currency operating income increased 14% as cost savings actions, lower delivered product costs and pricing more than offset the impact of lower volume.

Acquisition adjusted fixed currency sales increased 4%, led by Pest Elimination. Acquisition adjusted fixed currency operating income decreased 4% as pricing and sales volume gains were more than offset by investments in the business and comparison to strong income growth in the year ago period.

Corporate

Corporate expense includes amortization expense of $39 million in the fourth quarter of 2019 and $41 million in the fourth quarter of 2018 related to the Nalco merger intangible assets. Corporate expense also includes net special charges of $77 million in 2019. These charges are primarily related to the planned separation of the ChampionX business, the previously announced efficiency initiative and the Healthcare product recall.

Special gains and charges for the fourth quarter of 2019, which also includes a net pension settlement and curtailment charge of $9 million recorded in Other (income) expense, were a net charge of $86 million ($72 million after tax).

Special gains and charges for the fourth quarter of 2018 were a net charge of $19 million ($14 million after tax) primarily related to the previously announced efficiency initiative.

ChampionX Separation

On December 19, 2019, Ecolab announced a definitive agreement in which Ecolab will separate the ChampionX business and simultaneously combine it with Apergy Corporation in a tax-free Reverse Morris Trust transaction.

We continue to believe this transaction is an excellent development for both Apergy and ChampionX, bringing together two established industry leaders, creating a strong and focused entity with an experienced management team, considerable scale and a broader range of solutions that better serve customer needs. These commercial merits, together with the significant synergies expected to be realized through the combination, are expected to drive attractive shareholder value for Ecolab shareholders.

The transaction is subject to customary closing conditions, including the effectiveness of Apergy and Ecolab SEC filings, Apergy shareholder approval, consummation of the ChampionX separation from Ecolab, and regulatory approvals. The transaction is expected to be completed by the end of the second quarter of 2020. Upon completion of the separation, ChampionX will be accounted as a discontinued operation for Ecolab’s full year 2020.

For the full year 2019, ChampionX unaudited sales were approximately $2.3 billion, with unaudited operating income of approximately $180 million (which includes Ecolab allocated costs).

Following the separation, ongoing Ecolab will also be impacted by stranded costs of approximately $70 million, which are expected to be offset by cost savings actions through 2021.

Business Outlook

The outlook provided below is for consolidated Ecolab operations and continues to include the ChampionX business.

2020

Ecolab expects full year 2020 adjusted diluted earnings per share in the $6.33 to $6.53 range, rising 9% to 12% over 2019. This forecast includes an estimated unfavorable $0.05 per share impact from the effects of the coronavirus outbreak in the first quarter; we are not yet able to estimate and forecast the impact for the second quarter through fourth quarter.

We expect good acquisition adjusted fixed currency sales growth in 2020 as improving volume gains and continued pricing benefit sales. We look for improving adjusted gross margin reflecting volume gains, pricing, flattish delivered product costs and cost efficiency actions. We expect a lower SG&A ratio to sales, lower other income as lower interest rates result in unfavorable pension expense, higher interest expense and a similar adjusted tax rate versus 2019.

We expect currently quantifiable special charges in 2020 to be $0.45 to $0.55 per share principally related to the previously announced efficiency initiative, planned ChampionX separation and integration of previously announced acquisitions. In addition, the discrete tax item related to excess tax benefits on share-based compensation is expected to be favorable. Other than this discrete tax item and special gains and charges noted above, other such amounts are not currently quantifiable.

At current rates of exchange, we expect foreign currency translation to have an unfavorable $0.04 impact on full year diluted earnings per share.

Our detailed outlook for the full year of 2020 is as follows:

Reported 2019 diluted earnings per share of $5.33 included special gains and charges and discrete tax items. Excluding these items, 2019 adjusted diluted earnings per share were $5.82.

Ecolab expects the year-on-year 2020 adjusted diluted earnings per share growth for ongoing Ecolab operations, excluding the ChampionX business from both years, will show a similar percentage increase as its consolidated forecasted adjusted diluted earnings per share discussed above.

2020 — First Quarter

Ecolab expects first quarter 2020 adjusted diluted earnings per share in the $1.05 to $1.13 range, rising 2% to 10% compared with adjusted diluted earnings per share of $1.03 a year ago, with this forecast including an estimated unfavorable $0.05 per share impact from the effects of the coronavirus outbreak.

We expect currently quantifiable special charges in the first quarter of 2020 to be approximately $0.30 per share, principally related to the planned ChampionX business separation, previously announced efficiency initiative and integration of previously announced acquisitions. In addition, the discrete tax item related to excess tax benefits on share-based compensation is expected to be favorable. Other than this discrete tax item and special gains and charges noted above, other such amounts are not currently quantifiable.

At current rates of exchange, we expect foreign currency to have an unfavorable $0.01 impact on first quarter diluted earnings per share.

Our detailed outlook for the first quarter of 2020 is as follows:

Reported first quarter 2019 diluted earnings per share of $1.01 included special gains and charges and discrete tax items. Excluding these items, first quarter 2019 adjusted diluted earnings per share were $1.03.

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 include:

• 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
• adjusted diluted operating 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 cost of sales, gross margin, operating income, other (income) expense and interest expense exclude the impact of special (gains) and charges, 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, discrete tax items and certain external factors 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 2019. 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.

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.
