MALVERN, PA, November 9, 2021 -- Ecovyst Inc. (NYSE: ECVT) (“Ecovyst” or the “Company”) today reported results from continuing operations for the third quarter ended September 30, 2021.

Sales of $167.4 million increased 28.1%, largely driven by higher volumes in chemical catalysts and polyethylene, catalysts used in renewable fuel materials, and the pass through of higher sulfur and other material costs. Net income was $4.7 million with a diluted income per share of $0.03. Adjusted net income was $25.5 million with an Adjusted diluted EPS of $0.19. Adjusted EBITDA of $69.4 million was up 44.3% driven by higher volumes across the portfolio, favorable product mix, and the benefit from the Chem32 acquisition.

“This quarter was our first Ecovyst stand-alone quarter. We outperformed both sequentially and year-on-year, delivering significant growth and highly expanded margins. This was supported by continued demand recovery and secular growth trends in our key end uses, and complemented by our team’s immaculate execution. As a result, we believe we are well positioned to achieve the upper end of our previous 2021 Adjusted EBITDA guidance range and to increase our Sales and Adjusted Free Cash Flow outlook. I am especially proud of our success in helping enable our leading global customers navigate through their supply chain and storm challenges,” said Belgacem Chariag, Ecovyst Chairman, President and Chief Executive Officer.

“Our performance year-to-date demonstrates the critical nature of our products and services, the resilience of our portfolio, the operational network strengths, and the team expertise. We remain confident that we are on track to capitalize on the accelerating favorable demand trends projected to continue through 2022 and beyond.”

Review of Segment Results and Business Trends

The third quarter acceleration in economic recovery resulted in higher demand for most of our products and services. U.S. refinery utilization, a key indicator for both of our businesses, rebounded during the third quarter, driven by improvement in vehicle miles traveled, which increased approximately 12% year-to-date versus this time last year. We anticipate demand trends to reach pre-pandemic levels by 2022, driven by the projected recovery in traditional fuels, growth in renewable fuels and a continued rise of key end uses for virgin sulfuric acid and polyethylene.

Ecoservices

Sales of $137.5 million rose 27.8% from the prior year driven by higher regeneration services volumes, favorable virgin sulfuric acid pricing, the contribution from the Chem32 acquisition and $15 million of pass-through of higher sulfur costs. Adjusted EBITDA of $51.9 million increased 17.2%, largely attributable to higher regeneration volumes, favorable virgin sulfuric acid pricing, and the addition of the Chem32 catalyst activation business. This more than offset a scheduled maintenance outage that impacted the quarter by approximately $2 million, as there was no comparable outage in the prior year.

Increased vehicle miles driven combined with the rising standards for higher efficiency and lower emissions gasoline are driving alkylate utilization higher and consequently increasing demand for sulfuric acid regeneration services. Virgin sulfuric acid volumes continue to benefit from growing uses in mining applications for green infrastructure and electrification trends. Strong demand for construction-related materials has also supported the recovery in a broad range of industrial applications for virgin acid uses. These favorable trends continue to offset a slower return for automotive production due to supply chain challenges expected to persist through most of 2022. The catalyst activation services business continued to exhibit rapid growth from increasing renewable fuels production.

Catalyst Technologies

Sales of $29.9 million increased 29.4% from the same period in 2020, benefiting from continued robust demand for polyethylene catalysts and the timing of chemical catalysts sales, including methyl methacrylate. Zeolyst JV sales of $32.8 million rose 23.5% from the same period in 2020 due to rapidly growing demand for catalysts used in renewable fuels and the demand recovery for emission control catalysts, despite the supply chain impacts on vehicle production. Adjusted EBITDA of $25.5 million increased 116.1% as a result of higher volumes, strong product mix and improved manufacturing network efficiencies.

Polyethylene demand remains resilient, driven by the growing consumer demand for films and packaging. Higher refinery utilization rates are increasing catalyst demand for both traditional and renewable fuels on the continued recovery in vehicle miles traveled. In particular, as traditional fuels demand returns to pre-pandemic levels, hydrocracking catalyst volumes are expected to increase through 2022. Emission control catalyst demand is expected to demonstrate sequential improvement through 2022 as heavy duty diesel production rates meet increasing demand.

Cash Flows and Balance Sheet

Consolidated cash flows from operating activities was $84.9 million, compared to $56.4 million for the same period in 2020. The increase was driven by an increase in operating profit and an increase in dividends received from the Zeolyst JV. At September 30, 2021, the Company had total gross debt of $897.8 million and available liquidity of $165.6 million, including cash and cash equivalents of $104.8 million. The Company expects a net debt to Adjusted EBITDA leverage ratio in the mid 3x range by year-end 2021.

Presentation of Non-GAAP Financial Measures

In addition to the results provided in accordance with U.S. generally accepted accounting principles (“GAAP”) throughout this press release, the Company has provided non-GAAP financial measures — Adjusted EBITDA, Adjusted EBITDA margin, Adjusted net income, Adjusted free cash flow, Adjusted diluted EPS, and net debt (collectively, “Non-GAAP Financial Measures”) — which present results on a basis adjusted for certain items. The Company uses these Non-GAAP Financial Measures for business planning purposes and in measuring its performance relative to that of its competitors. The Company believes that these Non-GAAP Financial Measures are useful financial metrics to assess its operating performance from period-to-period by excluding certain items that the Company believes are not representative of its core business. These Non-GAAP Financial Measures are not intended to replace, and should not be considered superior to, the presentation of the Company’s financial results in accordance with GAAP. The use of the Non-GAAP Financial Measures terms may differ from similar measures reported by other companies and may not be comparable to other similarly titled measures. These Non-GAAP Financial Measures are reconciled from the respective measures under GAAP in the appendix below.

The Company is not able to provide a reconciliation of its non-GAAP financial guidance to the corresponding GAAP measures without unreasonable effort because of the inherent difficulty in forecasting and quantifying certain amounts necessary for such a reconciliation such as certain non-cash, nonrecurring or other items that are included in net income and EBITDA as well as the related tax impacts of these items and asset dispositions / acquisitions and changes in foreign currency exchange rates that are included in cash flow, due to the uncertainty and variability of the nature and amount of these future charges and costs.

Zeolyst Joint Venture

The Company’s zeolite catalysts product group operates through its Zeolyst Joint Venture, which is accounted for as an equity method investment in accordance with GAAP. The presentation of the Zeolyst Joint Venture’s sales represents 50% of the sales of the Zeolyst Joint Venture. The Company does not record sales by the Zeolyst Joint Venture as revenue and such sales are not consolidated within the Company’s results of operations. However, the Company’s Adjusted EBITDA reflects the share of earnings of the Zeolyst Joint Venture that have been recorded as equity in net income from affiliated companies in the Company’s consolidated statements of income for such periods and includes Zeolyst Joint Venture adjustments on a proportionate basis based on the Company’s 50% ownership interest. Accordingly, the Company’s Adjusted EBITDA margins are calculated including 50% of the sales of the Zeolyst Joint Venture for the relevant periods in the denominator.

Descriptions to Ecovyst Non-GAAP Reconciliations

(a)We use Adjusted EBITDA as a performance measure to evaluate our financial results. Because the 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 primarily related 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.

(i)Other costs consist of certain expenses that are not core to our ongoing business operations, including environmental remediation-related costs, capital and franchise taxes. Included in this line-item are rounding discrepancies that may arise from rounding from dollars (in thousands) to dollars (in millions).

See Appendix Table A-1 for Descriptions to Ecovyst Non-GAAP Reconciliations in the table above.

(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)Due to the sale of the Performance Chemicals business, the tax rates used to value deferred tax assets (“DTAs”) and deferred tax liabilities (“DTLs”) needs to be adjusted. Given it is a direct result of the sale of discontinued operations and the need to adjust the tax rate arose because of discontinued operations, the impact of revaluing the reporting entity’s DTAs and DTLs are reflected in continuing operations.

Net cash provided by (used in) investing activities(3)		$	866.1	$	(42.1)
Net cash used in financing activities		$	(978.7)	$	(10.2)

(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, net interest proceeds on swaps designated as net investment hedges, the cash paid for segment disposals and cash paid for debt financing costs included in cash from operating activities. 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.
