The Company’s Refining Services segment typically experiences seasonal fluctuations as a result of higher demand for gasoline products in the summer months and lower demand in the winter months. These demand fluctuations result in higher sales and working capital requirements in the second and third quarters.

The Company’s regeneration services product group, which is a part of the Company’s Ecoservices segment, typically experiences seasonal fluctuations as a result of higher demand for gasoline products in the summer months and lower demand in the winter months. These demand fluctuations result in higher sales and working capital requirements in the second and third quarters.

2. New Accounting Standards:

Recently Adopted Accounting Standards

In December 2019, the ~~FASB~~Financial Accounting Standards Board (“FASB”) issued new guidance to ~~simplify~~reduce the complexity in accounting for income taxes by removing certain exceptions to the general principles and ~~also simplification of~~simplifying areas such as franchise taxes, step-up in tax basis goodwill, separate entity financial statements and interim recognition of enactment of tax laws or rate changes. The new guidance is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal ~~years, with early adoption permitted.~~years. The Company adopted the new guidance effective January 1, 2021, with no material impact to the Company’s condensed consolidated financial position, results of operations or cash flows.

Accounting Standards Not Yet Adopted

In March 2020, the FASB issued guidance to address certain accounting consequences from the anticipated transition from the use of the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The new guidance contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance is optional and may be elected over time as reference rate reform activities occur. The Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based on matches the index of the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.

Contract Assets and Liabilities

A contract asset is a right to consideration in exchange for goods that the Company has transferred to a customer when that right is conditional on something other than the passage of time. A contract liability exists when the Company receives consideration in advance of performance obligations being satisfied. The Company has 0 contract assets or liabilities on its condensed consolidated balance sheets as of ~~March 31,~~June 30, 2021 and December 31, 2020. For the three and six months ended ~~March 31,~~June 30, 2021 and 2020, revenue recognized from performance obligations related to prior periods was not material.

5. Fair Value Measurements:

Fair values are based on quoted market prices when available. When market prices are not available, fair values are generally estimated using discounted cash flow analyses, incorporating current market inputs for similar financial instruments with comparable terms and credit quality. In instances where there is little or no market activity for the same or similar instruments, the Company estimates fair values using methods, models and assumptions that management believes a hypothetical market participant would use to determine a current transaction price. These valuation techniques involve some level of management estimation and judgment that becomes significant with increasingly complex instruments or pricing models. Where appropriate, adjustments are included to reflect the risk inherent in a particular methodology, model or input used.

The Company’s financial assets and liabilities carried at fair value have been classified based upon a fair value hierarchy. The hierarchy gives the highest ranking to fair values determined using unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest ranking to fair values determined using methodologies and models with unobservable inputs (Level 3). The classification of an asset or a liability is based on the lowest level input that is significant to its measurement. For example, a Level 3 fair value measurement may include inputs that are both observable (Levels 1 and 2) and unobservable (Level 3). The levels of the fair value hierarchy are as follows:

•Level 1—Values are unadjusted quoted prices for identical assets and liabilities in active markets accessible at the measurement date. Active markets provide pricing data for trades occurring at least weekly and include exchanges and dealer markets.

(Dollars in thousands, except share and per share amounts)

(unaudited)

•Level 2—Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices from those willing to trade in markets that are not active, or other inputs that are observable or can be corroborated by market data for the term of the instrument. Such inputs include market interest rates and volatilities, spreads and yield curves.

•Level 3—Certain inputs are unobservable (supported by little or no market activity) and significant to the fair value measurement. Unobservable inputs reflect the Company’s best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date.

The following table presents information about the Company’s assets and liabilities that were measured at fair value on a recurring basis as of ~~March 31,~~June 30, 2021 and December 31, 2020, and indicates the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value.

Derivative contracts

Derivative assets and liabilities can be exchange-traded or traded over-the-counter (“OTC”). The Company generally values exchange-traded derivatives using models that calibrate to market transactions and eliminate timing differences between the closing price of the exchange-traded derivatives and their underlying instruments. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, model calibration to market transactions, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. When models are used, the selection of a particular model to value an OTC derivative depends on the contractual terms of, and specific risks inherent in, the instrument as well as the availability of pricing information in the market. The Company generally uses similar models to value similar instruments. Valuation models require a variety of inputs, including contractual terms, market prices and rates, forward curves, measures of volatility, and correlations of such inputs. For OTC derivatives that trade in liquid markets, such as forward contracts, swaps and options, model inputs can generally be corroborated by observable market data by correlation or other means, and model selection does not involve significant management judgment.

During the ~~quarter~~six months ended ~~March 31,~~June 30, 2021, ~~the~~the Company had interest rate caps ~~and cross-currency swaps~~ that were fair valued using Level 2 inputs. In March 2021, the Company settled its cross-currency swaps, which were used as a hedging instrument of its net investment in foreign assets in its Performance Chemicals segment. Refer to Note 14 of these condensed consolidated financial statements for additional information. In addition, the Company applies a credit valuation adjustment to reflect credit risk which is calculated based on credit default swaps. To the extent that the Company’s net exposure under a specific master agreement is an asset, the Company utilizes the counterparty’s default swap rate. If the net exposure under a specific master agreement is a liability, the Company utilizes a default swap rate comparable to ~~PQ Group Holdings.~~Ecovyst. The credit valuation adjustment is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume the Company’s liabilities or that a market participant would be willing to pay for the Company’s assets.

Treasury Stock Repurchases

Stock Repurchase Program

The Company records repurchases of its common stock for treasury at cost. Upon the reissuance of the Company’s common stock from treasury, differences between the proceeds from reissuance and the average cost of the treasury stock are credited or charged to capital in excess of par value to the extent of prior credits related to the reissuance of treasury stock. If no such credits exist, the differences are charged to retained earnings.

On March 12, 2020, the Company’s Board of Directors (the “Board”) approved a plan to purchase up to $50,000 of ~~PQ Group Holdings~~Ecovyst Inc. common stock under a stock repurchase program approved by the Company’s ~~Board of Directors.~~Board. The Company may repurchase shares from time to time for cash in open market transactions or in privately negotiated transactions in accordance with applicable federal securities laws. The Company will determine the timing and the amount of any repurchases based on its evaluation of market conditions, share price and other factors. The stock repurchase program is valid until March 2022.

During the three months ended March 31, 2020, the Company repurchased 211,700 shares on the open market at an average price of $9.73, for a total of $2,059. The Company has ~~not~~0t made any additional repurchases under the program through ~~March 31,~~June 30, 2021. As of ~~March 31,~~June 30, 2021, $47,941 was available for additional share repurchases under the program.

Tax Withholdings on Equity Award Vesting

In connection with the vesting of restricted stock awards, restricted stock units and performance stock units, shares of common stock may be delivered to the Company by employees to satisfy withholding tax obligations at the instruction of the employee award holders. These transactions when they occur are accounted for as stock repurchases by the Company, with the shares returned to treasury stock at a cost representing the payment by the Company of the tax obligations on behalf of the employees in lieu of shares for the vesting unit. The fair value of the shares withheld to cover tax payments were $1,470 and $1,830 for the six months ended June 30, 2021 and 2020, respectively.

7. Acquisition:

On March 1, 2021 (the “Closing Date”), the Company completed the acquisition of Chem32, LLC (“Chem32”) as part of a stock transaction (the “Acquisition”) for $44,000 in cash. The net cash paid on the closing date by the Company was $41,994, after certain customary adjustments for indebtedness, working capital, cash and a holdback amount pursuant to the agreement. Based in Orange, Texas, Chem32 is a leader in ex situ pre-sulfiding and pre-activation for hydro-processing catalysts.

The Acquisition was accounted for using the acquisition method of accounting. Under the acquisition method, the purchase price was allocated to the identifiable net assets acquired based on the fair values of the identifiable assets acquired and liabilities assumed as of the Closing Date. The excess of the purchase price over fair values of the identifiable net assets acquired was recorded to goodwill.

The following table sets forth the calculation and preliminary allocation of the purchase price to the identifiable net assets acquired with respect to the Acquisition:


	Provisional Purchase Price Allocation
Cash paid, net of cash acquired	$	41,994
Holdback	2,000
Total consideration, net of cash acquired	$	43,994

Recognized amounts of identifiable assets acquired and liabilities assumed:
Receivables	$	1,368
Inventories	204
Prepaid and other current assets	351
Property, plant and equipment	5,046

Other long-term assets	38
Fair value of assets acquired	7,007

Accounts payable	207
Accrued liabilities	452



Fair value of net identifiable assets acquired	6,348
Goodwill	37,646
	$	43,994

The valuation of the identifiable assets and liabilities included in the table above is preliminary and is subject to change, as the Company is in the process of evaluating the information required to determine the fair values of certain identifiable assets and liabilities acquired, including inventory, property, plant and equipment and intangible assets. An increased portion of the purchase price allocated to the identifiable net assets acquired will reduce the amount recognized for goodwill and may result in increased cost of goods sold, depreciation and/or amortization expense. Adjustments to the provisional amounts during the measurement period that result in changes to depreciation, amortization or other income effects will be recognized in the reporting period(s) in which the adjustments are determined.

The Company’s condensed consolidated financial statements include Chem32’s results of operations from the Closing Date through ~~March 31,~~June 30, 2021. Net sales and net income attributable to Chem32 during this period are included in the Company’s condensed consolidated statement of in~~come~~income and are immaterial for the ~~period~~periods presented. Pro forma financial information has not been presented as it is immaterial for the three and six months ended ~~March 31,~~June 30, 2021 and 2020.

The Company believes that the Acquisition will enable it to offer a more robust portfolio of services within the refining industry leveraging our existing relationships, which contributed to a total purchase price that resulted in the recognition of goodwill. ~~All~~The Company assigned all of the goodwill ~~was assigned~~ to the ~~Company’s Refining Services~~Ecoservices segment. The goodwill associated with the Acquisition is deductible for tax purposes.

The fair value of a financial instrument is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. As of ~~March 31,~~June 30, 2021 and December 31, 2020, the fair value of the term loan facilities, senior secured and unsecured notes was ~~$1,428,967~~$1,431,568 and $1,427,123, respectively. The fair value is classified as Level 2 based upon the fair value hierarchy (see Note 5 to these condensed consolidated financial statements for further information on fair value measurements).

2021 Term Loan Facility

In June 2021, PQ Corporation (“PQ Corp”), an indirect, wholly owned subsidiary of Ecovyst prior to the closing of the sale of the Performance Chemicals business, and Ecovyst Catalyst Technologies LLC (“Ecovyst LLC” and, following the closing of the sale of the Performance Chemicals business, the “Borrower”), an indirect, wholly owned subsidiary of the Company, entered into an agreement for a new senior secured term loan facility in an aggregate principal amount of $900,000 with an original issue discount of 0.25% and interest at a floating rate of LIBOR (with a 0.5% minimum LIBOR floor) plus 2.75% per annum (or, depending on the Borrower’s first lien net leverage ratio, 2.5%). The proceeds were used to pay in full the 2020 Term Loan Facility, partially pay the 2016 Term Loan Facility and pay the associated fees and expenses. The new senior secured term loan facility requires scheduled quarterly amortization payments, each equal to 0.25% of the original principal amount of the loans under the new senior secured term loan facility.

As a result of amending the term loan facilities during the three and six months ended June 30, 2021, the Company recorded $5,736 of new creditor and third-party financing costs as debt extinguishment costs. In addition, previous unamortized deferred financing costs of $1,725 and original issue discount of $3,664 associated with the previously outstanding debt were written off as debt extinguishment costs.

ABL Facility

In June 2021, PQ Corp also entered into a third amendment agreement (the “ABL Amendment”), which amended its ABL Credit Agreement, dated as of May 4, 2016 (the “ABL Credit Agreement” and, as amended by the ABL Amendment, the “Amended ABL Credit Agreement”). The ABL Amendment amended the ABL Credit Agreement to, among other things, following the sale of Performance Chemicals, decrease the aggregate amount of revolving loan commitments available to the borrowers thereunder by an aggregate amount of $150,000 to $100,000, consisting of $90,000 in U.S. commitments and $10,000 on in European commitments and extended the maturity date with respect to borrowings under the Amended ABL Credit Agreement to August 2, 2026.

As a result of the ABL Amendment, unamortized deferred financing costs of $592 associated with the ABL Credit Agreement were written off as debt extinguishment costs during the three and six months ended June 30, 2021.

14. Financial Instruments:

The Company uses interest rate related derivative instruments to manage its exposure to changes in interest rates on its variable-rate debt instruments. The Company does not speculate using derivative instruments.

By using derivative financial instruments to hedge exposures to changes in interest rates, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is an asset, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is a liability, the Company owes the counterparty and therefore, the Company is not exposed to the counterparty’s credit risk in those circumstances. The Company minimizes counterparty credit risk in derivative instruments by entering into transactions with high quality counterparties. The derivative instruments entered into by the Company do not contain credit-risk-related contingent features.

Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates. The market risk associated with the Company’s derivative instruments is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

Use of Derivative Financial Instruments to Manage Interest Rate Risk. The Company is exposed to fluctuations in interest rates on its senior secured credit facilities. Changes in interest rates will not affect the market value of such debt but will affect the Company’s interest payments over the term of the loans. Likewise, an increase in interest rates could have a material impact on the Company’s cash flow. The Company hedges the interest rate fluctuations on debt obligations through interest rate cap agreements. The Company records these agreements at fair value as assets or liabilities in its consolidated balance sheet. As the derivatives are designated and qualify as cash flow hedges, the gains or losses on the interest rate cap agreements are recorded in stockholders’ equity as a component of OCI, net of tax. Reclassifications of the gains and losses on the interest rate cap agreements into earnings are recorded as part of interest expense in the condensed consolidated statements of income as the Company makes its interest payments on the hedged portion of its senior secured credit facilities. Fair value is determined based on estimated amounts that would be received or paid to terminate the contracts at the reporting date based on quoted market prices.

In November 2018, the Company entered into interest rate cap agreements to mitigate interest volatility from July 2020 through July 2022, with a cap rate of 3.50% on $500,000 of notional variable-rate debt and a $3,380 premium annuitized during the effective period. In February 2020, the Company restructured its $500,000 of notional variable-rate debt interest rate cap agreements from July 2020 through July 2022, to lower the interest cap rate to 2.50% with an incremental $130 premium annuitized during the effective period. In March 2020, the Company again amended such interest rate cap agreements to lower the cap rate to 0.84% from 2.50% on $500,000 of notional variable-rate debt and paid an additional incremental $900 premium annuitized during the effective period. The term remains unchanged from July 2020 through July 2022. The total cumulative annuitized premium on the $500,000 of notional variable-rate debt is $4,410. The cap rate in effect at ~~March 31,~~June 30, 2021 was 0.84% associated with the $500,000 of notional variable-rate debt.

In July 2020, the Company entered into additional interest rate cap agreements to mitigate interest rate volatility from August 2020 to August 2023, with a cap rate of 1.00% on $400,000 of notional variable-rate debt. The cap rate in effect at ~~March 31,~~June 30, 2021 was 1.00% associated with the $400,000 of notional variable-rate debt.

Use of Derivative Financial Instruments to Manage Foreign Currency Risk. The Company is exposed to risks related to its net investments in foreign operations due to fluctuations in foreign currency exchange rates, particularly between the United States dollar and the Euro. In February 2018, the Company entered into multiple cross-currency interest rate swap arrangements with an aggregate notional amount of €280,000 ~~($328,098 as of March 31, 2021)~~ to hedge this exposure on the net investments of certain of its Euro-denominated subsidiaries in its Performance Materials and Performance Chemicals businesses. The Company recorded these swap agreements at fair value as assets or liabilities in its consolidated balance sheet. As the derivatives are designated and qualify as net investment hedges, changes in the fair value of the swaps attributable to changes in the spot exchange rates are recognized in cumulative translation adjustment (“CTA”) within OCI and are held there until the hedged net investments are sold or substantially liquidated. Upon such sale or liquidation, the amount recognized in CTA is reclassified to earnings and reported in the same line item as the gain or loss on the liquidation of the net investments. Changes in the fair value of the swaps attributable to the cross-currency basis spread are excluded from the assessment of hedge effectiveness and are recorded in current period earnings.

In March 2021, as a result of the Performance Materials and Performance Chemicals divestitures, the Company settled its cross-currency swaps. At the date of settlement, the total notional value of the cross-currency swaps was $311,380. The Company paid $13,170 in cash to settle the swaps, which is included in net cash used in investing activities, discontinued operations in the Company’s condensed consolidated statement of cash flows for the ~~three~~six months ended ~~March 31,~~June 30, 2021, as the underlying subsidiary subject to the net investment hedging relationship is part of the Performance Chemicals business.

15. Income Taxes:

The effective income tax rate for the three months ended ~~March 31,~~June 30, 2021 was ~~65.4%~~(4,371.6)% compared to ~~33.2%~~(254.3)% for the three months ended ~~March 31,~~June 30, 2020. The effective income tax rate for the six months ended June 30, 2021 was (30.9)% compared to (562.5)% for the six months ended June 30, 2020. The Company’s effective income tax rate has fluctuated primarily due to changes in income mix, the impacts of the Global Intangible Low Taxed Income (“GILTI”) tax rules, discrete impacts related to intraperiod allocation revaluation of deferred tax assets and liabilities as a result of the Performance Chemicals divestiture, tax rate changes and changes in foreign exchange gains and losses, which create permanent differences in certain jurisdictions.

The difference between the U.S. federal statutory income tax rate and the Company’s effective income tax rate for the ~~three~~six months ended ~~March 31,~~June 30, 2021 was mainly due to state and local taxes, discrete tax impacts related to intraperiod allocation revaluation of deferred tax assets and liabilities as a result of the Performance Chemicals divestiture, tax rate changes and the tax effect of permanent differences related to foreign currency exchange gain or loss.

The difference between the U.S. federal statutory income tax rate and the Company’s effective income tax rate for the ~~three~~six months ended ~~March 31,~~June 30, 2020 was mainly due to ~~the impacts of GILTI,~~ state and local taxes, GILTI and the ~~tax effect~~impact of ~~permanent differences related to foreign currency exchange gain or loss.~~intra-period allocation as a result of the Performance Chemicals and Performance Materials businesses being classified as held for sale.

19. Stock-Based Compensation:

The Company is authorized to issue shares for common stock awards to employees, directors and affiliates of the Company in connection with the PQ Group Holdings Inc. 2017 Omnibus Incentive Plan, as Amended and Restated (the “2017 Plan”). During the ~~three~~six months ended ~~March 31,~~June 30, 2021, the Company granted 1,697,623 restricted stock units and 211,985 performance stock units (at target) under the 2017 Plan as part of its equity incentive compensation program. Each restricted stock unit provides the recipient with the right to receive a share of common stock subject to graded vesting terms based on service, which for the awards granted during the ~~three~~six months ended ~~March 31,~~June 30, 2021, generally requires approximately one year of service for members of the Company’s board of directors and approximately three years of service for employees.

The performance stock units granted during the ~~three~~six months ended ~~March 31,~~June 30, 2021 provide the recipients with the right to receive shares of common stock dependent on the achievement of a total shareholder return (“TSR”) goal, and are generally subject to the provision of service through the vesting date of the award. The performance period for the TSR goal is measured based on a three-year performance period from January 1, 2021 through December 31, 2023. The TSR goal is based on the Company’s actual TSR percentage increase over the performance period. Depending on the Company’s performance relative to the TSR goal, each performance stock unit award recipient is eligible to earn a percentage of the target number of shares granted to the recipient, ranging from 0 to 200%. The performance stock units, to the extent earned, will vest on the date the Company’s compensation and governance committee certifies the achievement of the performance metric for the three-year period ending December 31, 2023, which will occur subsequent to the end of the performance period but before the Company files its annual consolidated financial statements for the year ending December 31, 2023.

The value of the restricted stock units granted during the ~~three~~six months ended ~~March 31,~~June 30, 2021 was based on the average of the high and low trading prices of the Company’s common stock on the NYSE on the preceding trading day, in accordance with the Company’s policy for valuing such awards. Compensation expense related to the restricted stock units is recognized on a straight-line basis over the respective vesting period.

The TSR goal of the performance stock units granted during the ~~three~~six months ended ~~March 31,~~June 30, 2021 is considered a market condition as opposed to a vesting condition. Because a market condition is not considered a vesting condition, it is reflected in the grant date fair value of the award, and the associated compensation cost based on the fair value of the award is recognized over the performance period, regardless of whether the Company actually achieves the market condition or the level of achievement, as long as service is provided by the recipient. The Company used a Monte Carlo simulation to estimate the fair value of the portion of the awards subject to the TSR goal. The following table provides the assumptions used to determine the grant date fair value of the market condition-dependent / TSR goal-based portion of the Company’s performance stock units granted during the ~~three~~six months ended ~~March 31,~~June 30, 2021 using a Monte Carlo simulation:


Expected dividend yield	0		%
Risk-free interest rate	0.20		%
Expected volatility	41.70		%
Expected term (in years)	2.95
Grant date fair value	$	13.21

With the new grants of restricted stock units and performance stock units during the ~~three~~six months ended ~~March 31,~~June 30, 2021, unrecognized compensation cost at ~~March 31,~~June 30, 2021 was ~~$40,425~~$33,653 for restricted stock units and ~~$11,962~~$10,004 for performance stock units considered probable of vesting. The weighted-average period over which these costs are expected to be recognized at ~~March 31,~~June 30, 2021 is ~~2.02~~1.79 years for the restricted stock units and ~~1.66~~1.42 years for the performance stock units. Activity related to the Company’s stock options and restricted stock awards was not material for the ~~three~~six months ended ~~March 31,~~June 30, 2021. ~~No expense had previously been recognized related to these awards, as the performance vesting condition was not achieved nor considered probable of achievement.~~

20. Earnings per Share:

Basic earnings per share is calculated as income (loss) available to common stockholders, divided by the weighted average number of common shares outstanding during the period. The weighted average number of common shares outstanding during the period for the computation of basic earnings per share excludes restricted stock awards that have legally been issued but are nonvested during the period, as the sale of these shares is prohibited pending satisfaction of certain vesting conditions by the award recipients in order to earn the rights to the shares.

Diluted earnings per share is calculated as income (loss) available to common stockholders, divided by the weighted average number of common and potential common shares outstanding during the period, if dilutive. Potential common shares reflect (1) unvested restricted stock awards and restricted stock units with service vesting conditions, (2) performance stock units with vesting conditions considered probable of achievement and (3) options to purchase common stock, all of which have been included in the diluted earnings per share calculation using the treasury stock method.

Restricted stock awards and stock options with performance only vesting conditions were not included in the dilution calculation, as the performance targets have not been achieved nor were probable of achievement as of the end of the respective periods. On a weighted average basis, options to purchase ~~609,491~~603,159 shares of common stock at the historical exercise price of $16.97 per share and 241,316 shares of common stock at the historical exercise price of $17.50 per share for the three months ended ~~March 31,~~June 30, 2020, were excluded from the computation of diluted earnings per share, because the combination of the options’ exercise price and remaining unamortized stock-based compensation expense was greater than the average market price of the common shares. On a weighted average basis, options to purchase 606,325 shares of common stock at the historical exercise price of $16.97 per share and 241,316 shares of common stock at the historical exercise price of $17.50 per share for the six months ended June 30, 2020, were excluded from the computation of diluted earnings per share, because the combination of the options’ exercise price and remaining unamortized stock-based compensation expense was greater than the average market price of the common shares. The stock options with ana historical exercise price of $16.97 per share expire on October 2, 2027, while the stock options with ana historical exercise price of $17.50 per share expire on August 9, 2028. Anti-dilutive awards are not included in the dilution calculation, as their inclusion would have the effect of increasing diluted income per share.

Key Performance Indicators

Adjusted EBITDA and Adjusted Net Income

Adjusted EBITDA and adjusted net income are financial measures that are not prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and that we use to evaluate our operating performance, for business planning purposes and to measure our performance relative to that of our competitors. Adjusted EBITDA and adjusted net income are presented as key performance indicators as we believe these financial measures will enhance a prospective investor’s understanding of our results of operations and financial condition. EBITDA consists of net income (loss) attributable to continuing operations before interest, taxes, depreciation and amortization. Adjusted EBITDA consists of EBITDA adjusted for (i) non-operating income or expense, (ii) the impact of certain non-cash, nonrecurring or other items included in net income (loss) and EBITDA that we do not consider indicative of our ongoing operating performance, and (iii) depreciation, amortization and interest of our 50% share of the Zeolyst Joint Venture. Adjusted net income consists of net income (loss) attributable to continuing operations adjusted for (i) non-operating income or expense and (ii) the impact of certain non-cash, nonrecurring or other items included in net income (loss) that we do not consider indicative of our ongoing operating performance. We believe that these non-GAAP financial measures provide investors with useful financial metrics to assess our operating performance from period-to-period by excluding certain items that we believe are not representative of our core business.

You should not consider adjusted EBITDA or adjusted net income in isolation or as alternatives to the presentation of our financial results in accordance with GAAP. The presentation of adjusted EBITDA and adjusted net income financial measures may differ from similar measures reported by other companies and may not be comparable to other similarly titled measures. In evaluating adjusted EBITDA and adjusted net income, you should be aware that we are likely to incur expenses similar to those eliminated in this presentation in the future and that certain of these items could be considered recurring in nature. Our presentation of adjusted EBITDA and adjusted net income should not be construed as an inference that our future results will be unaffected by unusual or nonrecurring items. Reconciliations of adjusted EBITDA and adjusted net income to GAAP net income (loss) are included in the results of operations discussion that follows for each of the respective periods.

Key Factors and Trends Affecting Operating Results and Financial Condition

Sales

~~Market~~Overall economic demand has significantly rebounded since the 2020 lows that resulted from the impact of COVID-19. Refineries have seen demand return with increasing miles ~~driven.~~driven, recovery from winter storm Uri and a general increase in economic activity. Emission control and refining catalysts continue to lag, as vehicle builds have been slowed for numerous reasons including computer chip shortages, but show signs of rebound in the second half of 2021.

In February 2021, the Gulf Coast of the United States experienced significant and unexpectedly severe ~~weather.~~weather from winter storm Uri. Extended freezing temperatures led to ~~shutdowns~~slowdowns or ~~slowdowns~~shutdowns at nearly all refineries and caused extensive damage due to frozen piping. Some ~~plants~~refineries and facilities remained down for nearly a month. Our ~~Refining Services~~Ecoservices facilities located in the Gulf experienced damage, which required additional maintenance and ~~required certain repairs.~~some plant shutdowns.

Our Silica Catalysts product group, which is a part of our Catalyst Technologies segment, experiences demand fluctuations based upon the timing of our customer’s fixed bed catalyst replacements.

Sales in our ~~Refining Services~~Ecoservices and ~~Catalysts~~Catalyst Technologies segments are made on both a purchase order basis and pursuant to long-term contracts.

Cost of Goods Sold

Cost of goods sold consists of variable product costs, fixed manufacturing expenses, depreciation expense and freight expenses. Variable product costs include all raw materials, energy and packaging costs that are directly related to the manufacturing process. Fixed manufacturing expenses include ~~all~~ plant employment costs, manufacturing overhead and ~~periodic~~ maintenance costs.

The primary raw materials for our ~~Refining Services~~Ecoservices segment include spent sulfuric acid, sulfur, acids, bases (including sodium hydroxide, or “caustic soda”), and certain metals. Spent sulfuric acid for our Ecoservices segment is supplied by customers for a nominal charge as part of their contracts. The primary raw materials used in the manufacture of products in our ~~Catalysts~~Catalyst Technologies segments include sodium silicate and cesium hydroxide.

Most of our ~~Refining Services~~Ecoservices contracts feature take-or-pay volume protection and/or quarterly price adjustments for commodity inputs, labor, the Chemical Engineering Index (U.S. chemical plant construction cost index) and natural gas. ~~Spent acid for our Refining Services segment is supplied by customers for a nominal charge as part of their contracts.~~ Over 80% of our ~~Refining Services~~Ecoservices segment sales for the year ended December 31, 2020 were under contracts featuring quarterly price adjustments. The price adjustments generally reflect actual costs for producing sulfuric acid and tend to protect us from volatility in labor, fixed costs and raw material pricing. The take-or-pay volume protection allows us to cover fixed costs through intermittent, temporary production issues at customer refineries.

Table of Contents

While natural gas is not a direct feedstock for any product, natural gas powered furnaces are used to heat raw materials and create the chemical reactions necessary to produce end-products. We maintain multiple suppliers wherever possible, make forward purchases of natural gas in the United States and structure our customer contracts when possible to allow for the pass-through of raw material and natural gas costs.

~~Table of Contents~~

Joint Ventures

We account for our investments in our equity joint ventures under the equity method. Our largest joint venture, the Zeolyst Joint Venture, manufactures high performance, specialty, zeolite-based catalysts for use in the packaging and engineered plastics, emission control, refining and petrochemical industries and other areas of the broader chemicals industry. Demand for the Zeolyst Joint Venture products fluctuate based upon the timing of our customer’s fixed bed catalyst replacements. We share proportionally in the management of our joint ventures with the other parties to each such joint venture.

Seasonality

Our ~~Refining Services~~regeneration services product group, which is a part of our Ecoservices segment, typically experiences seasonal fluctuations as a result of higher demand for gasoline products in the summer months and lower demand in the winter months. These demand fluctuations result in higher sales and working capital requirements in the second and third quarter.

Foreign Currency

As a global business, we are subject to the impact of gains and losses on currency translations, which occur when the financial statements of foreign operations are translated into U.S. dollars. We operate in various geographies with approximately 10% of our sales for the ~~three~~six months ended ~~March 31,~~June 30, 2021 and the year ended December 31, 2020 are in currencies other than the U.S. dollar. Because our consolidated financial results are reported in U.S. dollars, sales or earnings generated in currencies other than the U.S. dollar can result in a significant increase or decrease in the amount of those sales and earnings when translated to U.S. dollars. The foreign currency to which we have the most significant exchange rate exposure is the British pound.

Gross Profit

•Gross profit ~~decreased $7.6~~increased $3.6 million to ~~$30.1 million.~~$38.5 million. The ~~decrease~~increase in gross profit was primarily due ~~to lower sales volumes and~~ an increase in ~~manufacturing costs, which was~~sales volumes partially offset by ~~favorable customer pricing~~higher production and ~~product mix.~~maintenance costs.

Operating Income

•Operating income ~~decreased~~increased by ~~$9.4~~$1.7 million to ~~$2.5~~$11.6 million. The ~~decrease~~increase in operating income was due to ~~a decrease~~an increase in gross profit, ~~during the current year period.~~which was partly offset by higher selling, general and administrative expenses.

(1)We define Segment Adjusted EBITDA as EBITDA adjusted for certain items as noted in the reconciliation below. Our management evaluates the performance of our segments and allocates resources based primarily on Segment Adjusted EBITDA. Segment Adjusted EBITDA does not represent cash flow for periods presented and should not be considered as an alternative to net income as an indicator of our operating performance or as an alternative to cash flows as a source of liquidity. Segment Adjusted EBITDA may not be comparable with EBITDA or Adjusted EBITDA as defined by other companies.

(2)The Adjusted EBITDA from the Zeolyst Joint Venture included in the ~~Catalysts~~Catalyst Technologies segment ~~is $10.5~~was $12.1 million for the three months ended ~~March 31,~~June 30, 2021, which includes ~~$5.2~~$6.8 million of equity in net income, excluding ~~$1.7~~$1.6 million of amortization of investment in affiliate step-up plus ~~$3.6~~$3.7 million of joint venture depreciation, amortization and interest. The Adjusted EBITDA from the Zeolyst Joint Venture included in the ~~Catalysts~~Catalyst Technologies segment ~~is $13.7~~was $16.9 million for the three months ended ~~March 31,~~June 30, 2020, which includes ~~$8.3~~$11.5 million of equity in net income, excluding $1.7 million of amortization of investment in affiliate step-up plus ~~$3.8~~$3.7 million of joint venture depreciation, amortization and interest.

(3)Our total Segment Adjusted EBITDA differs from our total consolidated Adjusted EBITDA due to unallocated corporate expenses.

Ecoservices: Adjusted EBITDA for the three months ended June 30, 2021 was $40.5 million, an increase of $5.5 million, or 15.7%, compared with $35.0 million for the three months ended June 30, 2020. The increase in Adjusted EBITDA was a result of a rebound in sales volumes as compared to the prior year period partially offset by higher plant “turnaround” maintenance expenses.

Catalyst Technologies: Adjusted EBITDA for the three months ended June 30, 2021 was $20.7 million, a decrease of $4.6 million, or 18.2%, compared with $25.3 million for the three months ended June 30, 2020. The decrease in Adjusted EBITDA was primarily a result of reduced volumes in the Zeolyst Joint Venture due to timing of customer orders.

(a)We use Adjusted EBITDA as a performance measure to evaluate our financial results. Because our Catalyst Technologies segment includes our 50% interest in the Zeolyst Joint Venture, we include an adjustment for our 50% proportionate share of depreciation, amortization and interest expense of the Zeolyst Joint Venture.

(b)Represents the amortization of the fair value adjustments associated with the equity affiliate investment in the Zeolyst Joint Venture as a result of the combination of the businesses of PQ Holdings Inc. and Eco Services Operations LLC in May 2016 (the “Business Combination”). We determined the fair value of the equity affiliate investment and the fair value step-up was then attributed to the underlying assets of the Zeolyst Joint Venture. Amortization is primarily related to the fair value adjustments associated with fixed assets and intangible assets, including customer relationships and technical know-how.

(c)When asset disposals occur, we remove the impact of net gain/loss of the disposed asset because such impact primarily reflects the non-cash write-off of long-lived assets no longer in use.

(d)Reflects the exclusion of the foreign currency transaction gains and losses in the statements of income, which primarily relates to the non-permanent intercompany debt denominated in local currency translated to U.S. dollars.

(e)Represents non-cash adjustments to the Company’s LIFO reserves for certain inventories in the U.S. that are valued using the LIFO method, which we believe provides a means of comparison to other companies that may not use the same basis of accounting for inventories.

(f)Relates to certain transaction costs, including debt financing, due diligence and other costs related to transactions that are completed, pending or abandoned, that we believe are not representative of our ongoing business operations.

(g)Includes the impact of restructuring, integration and business optimization expenses which are incremental costs that are not representative of our ongoing business operations.

(h)Represents adjustments for defined benefit pension plan (benefit) costs in our statements of income. All of our defined benefit pension plan obligations are under defined benefit pension plans that are frozen. As such, we do not view such income or expenses as core to our ongoing business operations.

(1)We define adjusted net income as net income attributable to Ecovyst adjusted for non-operating income or expense and the impact of certain non-cash or other items that are included in net income that we do not consider indicative of our ongoing operating performance. Adjusted net income is presented as a key performance indicator as we believe it will enhance a prospective investor’s understanding of our results of operations and financial condition. Adjusted net income may not be comparable with net income or adjusted net income as defined by other companies.

(2)Refer to the Adjusted EBITDA notes above for more information with respect to each adjustment.

(3)Due to reporting the Performance Chemicals business as held for sale in discontinued operations, the estimated tax rate used to value deferred tax assets (“DTAs”) and deferred tax liabilities (“DTLs”) needs to be adjusted to remove the Performance Chemicals rate. Given it is a direct result of the sale of discontinued operations and the need to adjust the estimated tax rate arose because of discontinued operations, the impact of revaluing the reporting entity’s DTAs and DTLs are reflected in continuing operations. Due to this revaluation being solely as a result of the Performance Chemicals divestiture and a non-cash item, it is treated as an addback.

The adjustments to net income attributable to Ecovyst Inc. are shown net of applicable tax rates as determined by the calculation of our quarterly tax provision under interim financial reporting for the three months ended June 30, 2021 and June 30, 2020, except for the foreign currency exchange loss, impacts of tax rate changes and the effects of the sale of assets for which the taxes are calculated as discrete items using the applicable statutory income tax rates.

Ecoservices: Sales in Ecoservices for the six months ended June 30, 2021 were $221.0 million, an increase of $29.9 million, or 15.6%, compared to sales of $191.1 million for the six months ended June 30, 2020. The increase in sales was due to higher average selling prices of $15.2 million and an increase in sales volumes of $14.7 million. Higher average selling prices benefited from the pass-through of higher sulfur costs of $12.8 million. Sales volumes increased as result of a rebound in gasoline production by refiners compared to the prior year period that was depressed by the COVID-19 pandemic.

Silica Catalysts: Sales in Silica Catalysts for the six months ended June 30, 2021 were $52.6 million, an increase of $2.5 million, or 5.0%, compared to sales of $50.1 million for the six months ended June 30, 2020. The increase in sales was primarily due to product mix of polyethylene catalysts resulting in an increase in pricing of $2.5 million.

Gross Profit

Gross profit for the six months ended June 30, 2021 was $68.6 million, a decrease of $4.0 million, or 5.5%, compared with $72.6 million for the six months ended June 30, 2020. The decrease in gross profit was due to higher maintenance costs and unfavorable inventory absorption, which was partially offset by favorable volumes in Ecoservices of $10.0 million.

The increase in manufacturing costs is due to one-time repair costs related to winter storms in the Gulf region, timing of plant “turnaround” maintenance expenditures and higher inventory absorption costs. Favorable product mix was a result of increased sales of higher-margin polyethylene catalysts. The increase in volumes was a result of a rebound in gasoline production by refiners compared to the prior year period that was burdened by the COVID-19 pandemic.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the six months ended June 30, 2021 was $44.0 million, a increase of $1.1 million as compared to $42.9 million for the six months ended June 30, 2020. The increase in selling, general and administrative expenses was due to increased compensation-related expenses, partially offset by income generated from the transition service agreement entered into as part of the sale of the Performance Materials business.

Other Operating Expense, Net

Other operating expense, net for the six months ended June 30, 2021 was $10.5 million, an increase of $2.6 million, compared with $7.9 million for the six months ended June 30, 2020. The increase in other operating expense, net was a result of severance charges incurred in the current year period.

Equity in Net Income of Affiliated Companies

Equity in net income of affiliated companies for the six months ended June 30, 2021 was $12.0 million, compared to $19.8 million for the six months ended June 30, 2020. The decrease was primarily due to $7.8 million of lower earnings from the Zeolyst Joint Venture during the six months ended June 30, 2021. The decline in earnings was a result of lower volume from deferred customer change-outs related to reduced output from oil refineries and heavy duty vehicle production, which led to a decrease in demand for our emission control and hydrocracking catalysts.

Interest expense, net for the six months ended June 30, 2021 was $19.2 million, a decrease of $11.2 million, as compared with $30.4 million for the six months ended June 30, 2020. The decrease in interest expense was primarily due to lower interest rates on our variable-rate debt.

Debt Extinguishment Costs

Debt extinguishment costs were $11.7 million and $2.5 million for the six months ended June 30, 2021 and 2020, respectively.

In June 2021, we entered into an agreement for a new senior secured term loan facility and used the proceeds to repay a portion of our existing term loan facilities. As a result of this transaction, we recorded $5.7 million of new creditor and third-party financing costs as debt extinguishment costs during the three months ended June 30, 2021. In addition, previous unamortized deferred financing costs of $1.7 million and original issue discount of $3.7 million associated with the previously outstanding debt were written off as debt extinguishment costs.

On February 7, 2020, we amended our existing senior secured term loan facility to reduce the applicable interest rates and extend the maturity of the facility to February 2027. We recorded $2.2 million of new creditor and third-party financing fees as debt extinguishment costs for the six months ended June 30, 2020. In addition, previously unamortized deferred financing costs of $0.1 million and original issue discount of $0.2 million associated with the existing senior secured term loan facility were written off as debt extinguishment costs for the six months ended June 30, 2020.

Other (Income) Expense, Net

Other expense, net for the six months ended June 30, 2021 was expense of $3.3 million, a decrease of $0.7 million, as compared with expense of $4.0 million for the six months ended June 30, 2020. The decrease in other expense, net primarily consisted of a decrease in franchise taxes.

Provision (Benefit) for Income Taxes

The benefit for income taxes for the six months ended June 30, 2021 was $2.5 million compared to a $26.3 million benefit for the six months ended June 30, 2020. The effective income tax rate for the six months ended June 30, 2021 was (30.9)% compared to (562.5)% for the six months ended June 30, 2020.

The Company’s effective income tax rate fluctuates primarily due to income mix, the impacts of GILTI, discrete impacts of the divestiture of the Performance Chemicals business, tax rate changes and changes in foreign exchange gains and losses, which create permanent differences in certain jurisdictions.

The difference between the U.S. federal statutory income tax rate and the Company’s effective income tax rate for the six months ended June 30, 2021 was mainly due to the impacts of GILTI, discrete tax impacts related to intraperiod allocation revaluation of deferred tax assets and liabilities as a result of the Performance Chemicals divestiture, tax rate changes and the tax effect of permanent differences related to foreign currency exchange gain or loss.

Net (Loss) Income Attributable to Ecovyst

For the foregoing reasons and after the effect of the non-controlling interest in earnings of subsidiaries for each period presented, net loss attributable to Ecovyst was $94.2 million for the six months ended June 30, 2021 compared with net income of $16.2 million for the six months ended June 30, 2020.

(a)We use Adjusted EBITDA as a performance measure to evaluate our financial results. Because our ~~Catalysts~~Catalyst Technologies segment includes our 50% interest in the Zeolyst Joint Venture, we include an adjustment for our 50% proportionate share of depreciation, amortization and interest expense of the Zeolyst Joint Venture.

(b)Represents the amortization of the fair value adjustments associated with the equity affiliate investment in the Zeolyst Joint Venture as a result of the combination of the businesses of PQ Holdings Inc. and Eco Services Operations LLC in May 2016. We determined the fair value of the equity affiliate investment and the fair value step-up was then attributed to the underlying assets of the Zeolyst Joint Venture. Amortization is primarily related to the fair value adjustments associated with fixed assets and intangible assets, including customer relationships and technical know-how.

(c)When asset disposals occur, we remove the impact of net gain/loss of the disposed asset because such impact primarily reflects the non-cash write-off of long-lived assets no longer in use.

(d)Reflects the exclusion of the foreign currency transaction gains and losses in the statements of income, primarily related to the non-permanent intercompany debt denominated in local currency translated to U.S. dollars.

(g)Includes the impact of restructuring, integration and business optimization expenses which are incremental costs that are not representative of our ongoing business operations.

Adjusted net income is presented as a key performance indicator as we believe it will enhance a prospective investor’s understanding of our results of operations and financial condition. Adjusted net income may not be comparable with net income or adjusted net income as defined by other companies.

Financial Condition, Liquidity and Capital Resources

Our primary sources of liquidity consist of cash ~~flow~~flows from operations, existing cash balances as well as funds available under our asset based lending revolving credit facility. We expect that ongoing requirements for debt service and capital expenditures will be funded from these sources of funds. Our primary liquidity requirements include funding working capital requirements (primarily inventory and accounts receivable, net of accounts payable and other accrued liabilities), debt service requirements and capital expenditures. Our capital expenditures include both maintenance of business, which include spending on maintenance and health, safety and environmental initiatives as well as growth, which includes spending to drive organic sales growth and cost savings initiatives.

We believe that our existing cash, cash equivalents and cash flows from operations, combined with availability under our asset based lending revolving credit facility, will be sufficient to meet our presently anticipated future cash needs for at least the next twelve months. We may also pursue strategic acquisition or divestiture opportunities, which may impact our future cash requirements. We may, from time to time, increase borrowings under our asset based lending revolving credit facility to meet our future cash needs. As of ~~March 31,~~June 30, 2021, we had cash and cash equivalents of ~~$55.2~~$55.8 million and availability of ~~$105.6~~$107.1 million under our asset based lending revolving credit facility, after giving effect to $17.8 million of outstanding letters of credit, for a total available liquidity of ~~$160.8~~$162.9 million. We did not have any revolving credit facility borrowings as of ~~March 31,~~June 30, 2021. As of ~~March 31,~~June 30, 2021, we were in compliance with all covenants under our debt agreements.

~~Included in our cash and cash equivalents~~On a continuing operations basis, we held an immaterial balance ~~as of March 31, 2021 was $0.8 million~~ of cash and cash equivalents ~~held~~ in foreign jurisdictions ~~on a continuing operations basis.~~as of June 30, 2021. We repatriate cash held outside of the United States from certain foreign subsidiaries in order to meet domestic liquidity needs. Depending on domestic and foreign cash balances, we have certain flexibility to repatriate funds in order to meet those needs. Specifically, we have an intercompany loan structure in place with ~~several of our~~ foreign subsidiaries that allows us to repatriate foreign cash in a tax efficient manner from those subsidiaries. ~~In certain cases, the repatriation~~Repatriation of foreign cash ~~under previous U.S. tax law had~~is generally ~~been subject to U.S. income taxes at the time of cash distribution. Due to the enactment of the TCJA in December 2017, future overseas earnings repatriation will generally no longer be~~not subject to U.S. federal income taxes at the time of cash distribution. However, ~~future~~ foreign earnings may still be t~~axed~~taxed for state income tax purposes, as well as subject to certain foreign withholding tax obligations, when cash amounts are distributed back to the U.S.

Our liquidity requirements are significant, primarily due to debt service requirements. As reported, our cash interest paid for the ~~three~~six months ended ~~March 31,~~June 30, 2021 and 2020 was approximately ~~$17.8~~$28.8 million and ~~$19.8~~$53.8 million, respectively. Before any impact of hedges, a one percent change in assumed interest rates for our variable interest credit facilities would have an annual impact of approximately ~~$11.3~~$2.3 million on interest expense. We hedge the interest rate fluctuations on debt obligations through interest rate cap agreements. As of ~~March 31,~~June 30, 2021, we had interest rate caps on $500.0 million of notional ~~variable~~variable-rate debt with a cap rate of 0.84% through July 2022 and $400.0 million of notional variable-rate debt with a cap rate of 1.00% through August 2023.

The following discussions related to our cash flows are presented on a continuing operations basis, which excludes the cash flows from our Performance Materials and Performance Chemicals businesses accounted for as discontinued operations. ~~The discussion related to our adjusted free cash flow metric is presented on a consolidated basis.~~

Net cash provided by operating activities was ~~$16.5~~$37.2 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021, compared to ~~$11.1~~$24.3 million provided for the ~~three~~six months ended ~~March 31,~~June 30, 2020. Cash generated by operating activities, other than changes in working capital, was ~~higher~~lower during the ~~three~~six months ended ~~March 31,~~June 30, 2021 by ~~$3.4~~$25.8 million compared to the same period in the prior year. The change in working capital during the ~~three~~six months ended ~~March 31,~~June 30, 2021 was favorable compared to the ~~three~~six months ended ~~March 31,~~June 30, 2020. Cash used to fund working capital was ~~$4.3~~$15.2 million and ~~$6.5~~$53.8 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021 and 2020, respectively.

The ~~increase~~decrease in cash generated by operating activities, other than changes in working capital, was ~~higher~~lower by ~~$3.4~~$25.8 million as compared to the prior year period primarily due to ~~an increase~~a decrease in dividends received from affiliated companies offset by a decline in operating profit.

The increase in cash from working capital of ~~$2.2~~$38.6 million as compared to the prior year was primarily due to favorable changes in accrued liabilities, inventories and accounts payable ~~and accrued liabilities~~ which were partially offset by unfavorable changes in accounts receivable and prepaid and other current assets.

The favorable change in accrued liabilities was driven by a decrease in current income taxes payable and lower interest accruals. The increase in cash provided by inventory changes was due to the timing of sales orders for our polyethylene catalysts in the current year period ~~and~~compared to an inventory build in the prior year period. The favorable change in accounts payable is due to the timing of capital spending and the favorable change in accrued liabilities relates to changes in various expense accruals. The unfavorable change in accounts receivable was driven by the ~~timing of collections on receivable balances.~~increase in sales within our Ecoservices segment.

Net cash used in investing activities was ~~$54.6~~$70.0 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021, compared to cash used of ~~$7.6~~$19.8 million during the same period in 2020. Cash used in investing activities consisted of utilizing ~~$12.6~~$28.0 million and ~~$10.0~~$22.2 million to fund capital expenditures during the ~~three~~six months ended ~~March 31,~~June 30, 2021 and 2020, respectively. During the ~~quarter~~six months ended ~~March 31,~~June 30, 2021, we acquired Chem32, LLC for $42.0 million. We received proceeds of $2.4 million related to the sale of non-core assets during the ~~three~~six months ended ~~March 31,~~June 30, 2020.

Net cash used in financing activities was ~~$1.5~~$5.0 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021, compared to net cash ~~provided~~used of ~~$52.5~~$6.7 million during the same period in 2020. Net cash used in financing activities was primarily driven by $3.5 million of debt issuance costs related to the 2021 Term Loan Facility and $1.5 million of stock repurchases during the ~~three~~six months ended ~~March 31,~~June 30, 2021. Net cash provided by financing activities was primarily driven by ~~$59.0~~$3.9 million of ~~net borrowings under our revolving credit facilities made through~~stock repurchases and $3.0 million of debt issuance costs the ~~three~~six months ended ~~March 31,~~June 30, 2020.

~~Adjusted Free Cash Flow~~

Adjusted free cash flow is a non-GAAP metric management reviews to gauge liquidity performance. Adjusted free cash flow is calculated as cash flow from operating activities less purchases of property, plant and equipment, adjusted for proceeds from the sale of assets, net interest proceeds on swaps designated as net investment hedges and the cash paid for costs related to segment disposals. For the three months ended March 31, 2021, adjusted free cash flow of $2.7 million was favorable to the prior year as cash flow from operating activities increased on a favorable change in working capital. Purchases of property, plant and equipment decreased as lower spending in discontinued operations was partially offset by higher maintenance of business capital in Refining Services.

~~(1)Excludes the company’s proportionate 50% share of capital expenditures from the Zeolyst joint venture.~~

~~(2)~~We define adjusted free cash flow as net cash provided by operating activities less purchases of property, plant and equipment, adjusted for proceeds from sale of assets and net interest proceeds on swaps designated as net investment hedges and the cash paid for costs related to segment disposals. Adjusted free cash flow is a non-GAAP financial measure that we believe will enhance a prospective investor’s understanding of our ability to generate additional cash from operations, including the reduction in cash paid for interest related to our cross-currency interest rate swaps, and is an important financial measure for use in evaluating our financial performance. Our presentation of adjusted free cash flow is not intended to replace, and should not be considered superior to, the presentation of our net cash provided by operating activities determined in accordance with GAAP. Additionally, our definition of adjusted free cash flow is limited, in that it does not represent residual cash flows available for discretionary expenditures, due to the fact that the measure does not deduct the payments required for debt service and other contractual obligations or payments made for business acquisitions. Therefore, we believe it is important to view adjusted free cash flow as a measure that provides supplemental information to our consolidated statements of cash flows. You should not consider adjusted free cash flow in isolation or as an alternative to the presentation of our financial results in accordance with GAAP. The presentation of adjusted free cash flow may differ from similar measures reported by other companies and may not be comparable to other similarly titled measures.

~~(3)~~Net cash used in investing activities includes purchases of property, plant and equipment, proceeds from sale of assets and net interest proceeds on swaps designated as net investment hedges, which are also included in our computation of adjusted free cash flow.

(1) A portion of the net cash proceeds from the closing of the sale of the Performance Chemicals business was used to repay the 2016 Term Loan Facility in full and to redeem all of the 5.750% Senior Notes due 2025.

As of ~~March 31,~~June 30, 2021, our total debt was $1,426.4 million, excluding the original issue discount of ~~$15.1~~$13.1 million and deferred financing fees of ~~$9.7~~$8.3 million for our senior secured credit facilities and notes. Our net debt as of ~~March 31,~~June 30, 2021 was ~~$1,371.2~~$1,370.6 million, including cash and cash equivalents of ~~$55.2~~$55.8 million. We may seek, subject to market conditions and other factors, opportunities to repurchase, refinance or otherwise reprice our debt.

In June 2021, PQ Corporation (“PQ Corp”), an indirect, wholly owned subsidiary of Ecovyst prior to the closing of the sale of the Performance Chemicals business, and Ecovyst Catalyst Technologies LLC (“Ecovyst LLC” and, following the closing of the sale of the Performance Chemicals business, the “Borrower”), an indirect, wholly owned subsidiary entered into an agreement for a new senior secured term loan facility in an aggregate principal amount of $900.0 million with an original issue discount of 0.25% and interest at a floating rate of LIBOR (with a 0.5% minimum LIBOR floor) plus 2.75% per annum (or, depending on the Borrower’s first lien net leverage ratio, 2.5%). The proceeds were used to pay in full the 2020 Term Loan Facility, partially pay the 2016 Term Loan Facility and pay the associated fees and expenses. The new senior secured term loan facility requires scheduled quarterly amortization payments, each equal to 0.25% of the original principal amount of the loans under the new senior secured term loan facility.

In June 2021, PQ Corp also entered into a third amendment agreement (the “ABL Amendment”), which amended the ABL Credit Agreement, dated as of May 4, 2016 (the “ABL Credit Agreement” and, as amended by the ABL Amendment, the “Amended ABL Credit Agreement”). The ABL Amendment amended the ABL Credit Agreement to, among other things, following the closing of the sale of the Performance Chemicals business, decrease the aggregate amount of revolving loan commitments available to the borrowers thereunder by an aggregate amount of $150.0 million to $100.0 million, consisting of $90.0 million in U.S. commitments and $10.0 million on in European commitments and extended the maturity date with respect to borrowings under the Amended ABL Credit Agreement to August 2, 2026.

Critical Accounting Policies and Estimates

We prepare our condensed consolidated financial statements in conformity with GAAP and our significant accounting policies are described in Note 2 to our audited consolidated financial statements included in our Annual Report on Form 10-K. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts and related disclosures. We base our estimates and judgments on historical experience and other relevant factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We evaluate our critical accounting estimates, assumptions and judgments on an ongoing basis.

There has been no material change in our critical accounting policies and use of estimates from those described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” included in our Annual Report on Form 10-K.

Accounting Standards Not Yet Adopted

See Note 2 to our unaudited condensed consolidated financial statements for a discussion of recently issued accounting standards and their effect on us.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our major market risk exposure is potential losses arising from changing rates and prices regarding foreign currency exchange rate risk, interest rate risk, commodity price risk and credit risk. The audit committee of our board of directors regularly reviews foreign exchange, interest rate and commodity hedging activity and monitors compliance with our hedging policy. We do not use financial instruments for speculative purposes, and we limit our hedging activity to the underlying economic exposure.

Table of Contents

There have been no material changes in the foreign exchange risk, interest rate risk, commodity risk or credit risk discussed in Item 7A., “Quantitative and Qualitative Disclosures about Market Risk,” included in our Annual Report on Form 10-K. other than the following item:

Foreign Exchange Risk

In March 2021, as a result of the Performance Materials and Performance Chemicals divestitures, we settled our cross-currency swaps. At the date of settlement, the total notional value of the cross-currency swaps was $311.4 million. We paid $13.2 million in cash to settle the swaps, which is included in net cash used in investing activities, discontinued operations in our condensed consolidated statement of cash flows for the ~~three~~six months ended ~~March 31,~~June 30, 2021, as the underlying subsidiary subject to the net investment hedging relationship is part of the Performance Chemicals business.

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of ~~March 31,~~June 30, 2021, the end of the period covered by this Quarterly Report on Form 10-Q.

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control Over Financial Reporting

No changes in our internal control over financial reporting occurred during the quarter ended ~~March 31,~~June 30, 2021 that materially affected, or which are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

From time to time we may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as personal injury, product liability and warranty claims, waste disposal practices, release of chemicals into the environment and other matters that may arise in the ordinary course of our business. We currently believe that there is no litigation pending that is likely to have a material adverse effect on our business. Regardless of the outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

ITEM 1A. RISK FACTORS.
