Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS OF APERGY

On December 18, 2019, Ecolab Inc. (“Ecolab”), ChampionX Holding Inc., currently a wholly owned subsidiary of Ecolab (“ChampionX”), Apergy Corporation (“Apergy”) and Athena Merger Sub, Inc., a wholly owned subsidiary of Apergy (“Merger Sub”) entered into the Agreement and Plan of Merger and Reorganization (the “Merger Agreement”), and Ecolab, ChampionX and Apergy entered into the Separation and Distribution Agreement (the “Separation Agreement”). Pursuant to the transactions contemplated by the Merger Agreement and the Separation Agreement (together the “Transactions”), Apergy will combine with Ecolab’s upstream energy business (“ChampionX Business”) through a merger of Merger Sub with ChampionX. In connection with the Transactions, Ecolab will effect (1) the separation of the ChampionX Business from Ecolab’s other businesses, (2) the distribution, (a) through the exchange offer whereby Ecolab is offering to its stockholders the ability to exchange all or a portion of their shares of Ecolab common stock for shares of ChampionX common stock, (the “Exchange Offer”) which shares of ChampionX common stock will be immediately exchanged for Apergy common stock, and if the Exchange Offer is not fully subscribed, of the remaining shares of ChampionX common stock owned by Ecolab on a pro rata basis to Ecolab stockholders whose shares of Ecolab stock remain outstanding after the consummation of the Exchange Offer (“the clean-up spin-off”), or (b) if the Exchange Offer is terminated by Ecolab without the exchange of shares (but the conditions to consummation of the Transactions have otherwise been satisfied), the distribution of all shares of ChampionX common stock on a pro rata basis to Ecolab stockholders in a spin-off, and (3) immediately thereafter, the merger of Merger Sub with and into ChampionX, with ChampionX becoming a wholly owned subsidiary of Apergy (the “Merger”). Following the consummation of the Transactions, ChampionX equityholders will own, in the aggregate, approximately 62% of the issued and outstanding Apergy common stock on a fully diluted basis and Apergy equityholders will own, in the aggregate, approximately 38% of the issued and outstanding Apergy common stock on a fully diluted basis.

The following unaudited pro forma condensed combined financial statements present the combination of the historical financial information of Apergy and ChampionX adjusted to give effect to the Merger to be accounted for under the acquisition method of accounting in accordance with Accounting Standards Codification 805, Business Combinations (“ASC 805”), with Apergy being considered the accounting acquirer of ChampionX. Under the acquisition method of accounting, the purchase price is allocated to the ChampionX identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair market values with any excess purchase price allocated to goodwill. The pro forma purchase price allocation is preliminary and was based on an estimate of the fair market values of the tangible and intangible assets and liabilities related to ChampionX. Following the completion of the Transactions, Apergy expects to complete the purchase price allocation considering the appraisal of ChampionX’s assets and liabilities at the level of detail necessary to finalize the required purchase price allocation. The purchase price utilized in the allocation will be based on the closing price of Apergy’s common stock immediately prior to closing. The pro forma adjustments included herein give effect to pro forma events that are (i) directly attributable to the Transactions, (ii) factually supportable and (iii) with respect to the statements of income/(loss), expected to have a continuing impact on the combined results of operations of the combined company. The final purchase price allocation may be different than that reflected in the preliminary pro forma purchase price allocation presented herein, and this difference may be material.

The unaudited pro forma condensed combined financial statements have been prepared by Apergy using assumptions that Apergy believes provide a reasonable basis for presenting the significant effects of the Transactions and do not reflect the costs of any integration activities or benefits that may result from realization of future cost savings from operating efficiencies or synergies that may result from the Transactions.

The unaudited pro forma condensed combined balance sheet combines the historical condensed consolidated balance sheet of Apergy and the historical combined balance sheet of ChampionX, as adjusted for the Separation Agreement, as of March 31, 2020, giving effect to the Transactions as if they had occurred on March 31, 2020. The unaudited pro forma condensed combined statements of income/(loss) combine the historical condensed consolidated statement of loss of Apergy and the historical combined statement of loss of ChampionX for the three months ended March 31, 2020 and the historical consolidated statement of income of Apergy and the historical combined statement of income of ChampionX for the year ended December 31, 2019, giving effect to the Transactions as if they had occurred on January 1, 2019. The unaudited pro forma condensed combined financial statements should be read in conjunction with:

The unaudited pro forma condensed combined financial statements do not purport to represent what the actual consolidated results of operations or financial position of the combined company would have been had the Transactions occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or financial position of the combined company on a standalone basis.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS OF APERGY

NOTE 1—DESCRIPTION OF THE TRANSACTIONS

On December 18, 2019, Ecolab, ChampionX, Apergy and Merger Sub entered into the Merger Agreement, and Ecolab, ChampionX and Apergy entered into the Separation Agreement, pursuant to which Apergy will combine with Ecolab’s ChampionX Business. In connection with the Transactions, Ecolab will effect (1) the separation of the ChampionX Business from Ecolab’s other businesses, (2) the distribution, through (a) the Exchange Offer, and if the Exchange Offer is not fully subscribed, the clean-up spin-off, or (b) if the Exchange Offer is terminated by Ecolab without the exchange of shares (but the conditions to consummation of the Transactions have otherwise been satisfied), the distribution of all shares of ChampionX common stock on a pro rata basis to Ecolab stockholders in a spin-off, and (3) immediately thereafter, the merger of Merger Sub with and into ChampionX, with ChampionX becoming a wholly owned subsidiary of Apergy. Following the consummation of the Transactions, ChampionX equityholders will own, in the aggregate, approximately 62% of the issued and outstanding Apergy common stock on a fully diluted basis and the Apergy equityholders will own, in the aggregate, approximately 38% of the issued and outstanding Apergy common stock on a fully diluted basis.

Acquisition-related transaction costs, such as investment banker, advisory, legal, valuation and other professional fees are not included as a component of consideration transferred but are expensed as incurred. During the three months ended March 31, 2020 and the year ended December 31, 2019, transaction costs incurred by Apergy were $11.1 million and $9.3 million, respectively. Additionally, the unaudited pro forma condensed combined balance sheet reflects a total of approximately $49.6 million of anticipated acquisition-related transaction costs to be incurred by Apergy, as an increase of accrued expenses and other liabilities with a corresponding decrease in retained earnings. The unaudited pro forma condensed combined balance sheet does not include an adjustment for ChampionX’s anticipated separation related expenses as these are incurred and paid by Ecolab. No tax effect was recorded for these costs as their deductibility has not been assessed. These costs are not presented in the unaudited pro forma condensed combined statements of operations because they will not have a continuing impact on the consolidated results of Apergy.

NOTE 2—BASIS OF PRESENTATION

The accompanying unaudited pro forma condensed combined financial statements of Apergy were prepared in accordance with Article 11 of Regulation S-X and present the pro forma statements of income/(loss) and pro forma balance sheet of the combined company based on the historical financial statements of Apergy and ChampionX, after giving effect to the Transactions and other transaction-related adjustments. The historical financial statements of Apergy and ChampionX have been adjusted in the accompanying pro forma financial statements to give effect to pro forma events that are (i) directly attributable to the Transactions, (ii) factually supportable and (iii) with respect to the statements of income/(loss), expected to have a continuing impact on the combined results of operations of the combined company.

The unaudited pro forma condensed combined balance sheet combines the historical consolidated balance sheet of Apergy and the historical combined balance sheet of ChampionX, as adjusted for the Separation Agreement, as of March 31, 2020, giving effect to the Transactions as if they had occurred on March 31, 2020.

The unaudited pro forma condensed combined statements of income/(loss) combine the historical consolidated statements of loss of Apergy and the historical combined statements of loss of ChampionX for the three months ended March 31, 2020, and the historical consolidated statements of income of Apergy and the historical combined statements of income of ChampionX for the year ended December 31, 2019, giving effect to the Transactions as if they had occurred at January 1, 2019.

The Merger will be accounted for as a business combination under ASC 805, with Apergy treated as the “acquirer” and ChampionX treated as the “acquired” company for accounting purposes.

NOTE 3—PRO FORMA CHAMPIONX ADJUSTMENTS

The following tables detail the historical combined financial statements of ChampionX, the pro forma adjustments related to the Separation Agreement, and reclassifications to conform to Apergy’s financial statement presentation.

NOTE 4—RECLASSIFICATION ADJUSTMENTS

The unaudited pro forma ChampionX adjusted statement of loss for the three months ended March 31, 2020 includes the following adjustments:

The unaudited pro forma ChampionX adjusted statement of income for the year ended December 31, 2019 includes the following adjustments:

NOTE 5—PRELIMINARY PURCHASE ACCOUNTING ADJUSTMENTS

The purchase price will be computed using the value of Apergy’s share price as of closing. Therefore, the estimated purchase price will fluctuate with the market price of Apergy’s common stock until closing. As a result, the final purchase price could differ significantly from the current estimate, which could materially impact the purchase price allocation. Any increase or decrease in the fair values of the net assets as compared with the unaudited pro forma condensed combined financial statements may change the amount of the total purchase consideration allocation to assets and liabilities and may impact the combined company’s statements of income/(loss) due to adjustments in depreciation and/or amortization of the adjusted assets or liabilities.

The pro forma purchase price allocation is preliminary and was based on an estimate of the fair market values of the tangible and intangible assets acquired and liabilities assumed related to ChampionX. Following the completion of the Transactions, additional information will be made available to Apergy to allow for the completion of the purchase price allocation considering the appraisal of ChampionX’s assets and liabilities at the level of detail necessary to finalize the required purchase price allocation.

Market capitalizations across the oil and gas industry have declined significantly since December 2019 due to the decline in commodity prices and the related imbalance of supply and demand due to the coronavirus (COVID-19). This imbalance has led to significantly depressed market capitalizations across the oil and gas industry. Continued decline in commodity prices could negatively affect the estimated Merger consideration transferred to the point where the Merger consideration no longer exceeds the fair value assigned to the assets acquired and liabilities assumed, resulting in a bargain purchase gain.

Apergy’s stock price declined 72% from $30.67 per share on December 18, 2019, the last trading day prior to announcement of the Merger, to $8.65 per share on May 14, 2020.

The following table summarizes the components of the estimated Merger consideration reflected in the unaudited pro forma condensed combined financial statements (in thousands, except per share amount):

Apergy assessed multiple scenarios considering the current market volatility. Continued market volatility would impact the amount of the goodwill or bargain purchase gain, as the value of the Merger consideration and the fair value of the net identifiable assets acquired will continue to fluctuate. Based upon current valuation assumptions, a 35% increase in Apergy’s share price will result in a total consideration of $1,490.1 million and corresponding goodwill of approximately $488.8 million. Likewise, based on current valuation assumptions, a 35% decrease in Apergy’s share price will result in consideration of $717.4 million and a $283.8 million bargain purchase gain.

The preliminary estimated purchase price is allocated as follows (in thousands):

The estimated intangible assets attributable to the Merger comprise the following (in thousands):

The estimate was determined by multiplying the increase or decrease in the fair value of the respective asset or liability over historical book value (excluding goodwill) by a blended statutory tax rate estimate of approximately 22.8%. This rate is subject to change when Apergy performs a complete tax analysis post-Transactions.
