Ecovyst Reports First Quarter 2025 Results and Reaffirms 2025 Guidance for Adjusted EBITDA

, /PRNewswire/ -- Ecovyst Inc. (NYSE: ECVT) ("Ecovyst" or the "Company"), a leading integrated and innovative global provider of advanced materials, specialty catalysts, virgin sulfuric acid and sulfuric acid regeneration services, today reported results for the first quarter ended March 31, 2025. First Quarter 2025 Results & Highlights Sales of $162.2 million, compared to $160.5 million in the first quarter of 2024 Net Loss of $3.6 million, compared to Net Income of $1.2 million in the year-ago quarter, with a net loss margin of 2.2% and diluted net loss per share of $0.03. Adjusted Net Income was $1.2 million with Adjusted Diluted Income per share of $0.01 Adjusted EBITDA of $38.9 million, compared to $45.5 million in the first quarter of 2024, with an Adjusted EBITDA margin of 19.5% Cash flows from operating activities were $10.3 million for the three months ended March 31, 2025, compared to $36.5 million for the three months ended March 31, 2024. Adjusted Free Cash Flow was $(13.0) million for the three months ended March 31, 2025, compared to $19.1 million for the three months ended March 31, 2024 Reaffirming full-year 2025 Adjusted EBITDA guidance Announced an agreement to acquire the sulfuric acid assets of Cornerstone Chemical Company, for $35 million, subject to regulatory approvals and customary closing conditions, with closing expected in the second quarter of 2025 "Ecovyst's businesses remained resilient in the first quarter of 2025. First quarter financial results for our Advanced Materials & Catalysts segment were stronger than anticipated due to favorability in sales timing for hydrocracking and specialty catalysts. Results for our Ecoservices segment were in line with our expectations, with higher costs and lower sales volume compared to the year-ago quarter reflecting the impact of our planned turnarounds as well as the sales impact associated with customer turnaround activity during the quarter," said Kurt J. Bitting, Ecovyst's Chief Executive Officer. "We anticipate that in early May the significant planned turnaround activity in our Ecoservices segment will be largely behind us. We expect high refinery utilization and the seasonal increase in gasoline demand to support increased activity for our regeneration services business beginning in the second quarter, and we anticipate strong demand in mining applications to benefit sales of virgin sulfuric acid over the balance of the year." "Ecovyst supports numerous industries that we believe are vital to fueling the economy and providing the critical materials needed to support the infrastructure and sustainable products required for the future. Our ongoing investments in Kansas City and Orange are evidence of the confidence we have in the long-term growth prospects for the end uses that we serve," said Bitting. "In addition, on March 18th, we announced that we had reached an agreement to acquire the Cornerstone Chemical sulfuric acid assets. We look forward to the anticipated closing of the transaction in the second quarter and expeditiously integrating it into the Ecoservices segment. We expect this acquisition will enhance our Gulf Coast network and expand our capacity to meet increased customer demand for virgin sulfuric acid and regeneration services." Review of Segment Results and Business Trends Ecoservices First quarter 2025 sales were $143.1 million, compared to $141.6 million in the first quarter of 2024. The increase in sales reflects pass-through of higher sulfur costs and favorable contractual pricing for regeneration services, partially offset by lower sales volume for regeneration services and for virgin sulfuric acid. First quarter 2025 Adjusted EBITDA was $28.5 million, compared to $41.5 million in the first quarter of 2024. The decrease reflects higher manufacturing costs, including costs associated with planned turnaround activity, less favorable absorption of fixed costs associated with inventory timing, and general inflation as well as lower sales volume arising from turnaround activity at Ecoservices sites and at customer facilities. Advanced Materials & Catalysts During the first quarter of 2025, Advanced Silicas sales were $19.1 million, compared to $18.9 million in the first quarter of 2024. The modest increase in sales resulted from higher sales of niche custom catalyst sales associated with order timing, partially offset by lower sales of advanced silicas used for the production of polyethylene. Our proportionate 50% share of first quarter sales for the Zeolyst Joint Venture was $37.7 million, compared to $23.5 million in the first quarter of 2024. The increase in Zeolyst Joint Venture sales reflects higher sales of hydrocracking catalysts and specialty catalysts associated with customer-driven sales timing. First quarter 2025 Adjusted EBITDA for Advanced Materials & Catalysts, which includes our 50% proportionate share of earnings from the Zeolyst Joint Venture, was $17.5 million, compared to $11.1 million in the first quarter of 2024, with the increase largely driven by higher sales volume within the Zeolyst Joint Venture. Cash Flows and Balance Sheet Cash flows from operating activities was $10.3 million for the three months ended March 31, 2025, compared to $36.5 million for the three months ended March 31, 2024. The decrease was primarily driven by the timing of dividends received from the Zeolyst Joint Venture. At March 31, 2025, the Company had cash and cash equivalents of $127.5 million, total gross debt of $868.6 million and availability under the ABL facility of $73.6 million, after giving effect to $3.3 million of outstanding letters of credit and no revolving credit facility borrowings outstanding, for total available liquidity of $201.1 million. The net debt to net income ratio was not meaningful as of March 31, 2025 and the net debt leverage ratio was 3.2x as of March 31, 2025. 2025 Financial Outlook We are reaffirming our full year Adjusted EBITDA guidance and increasing our guidance range for sales to reflect the expected pass-through impact of higher anticipated sulfur costs. Having completed major turnaround activities in the first quarter, and in anticipation of high refinery utilization and growing sulfuric acid demand in mining applications, we expect Ecoservices to benefit from higher sales volumes for regeneration services and for virgin sulfuric acid in the second quarter and for the remainder of 2025. We believe that favorable order timing within the Zeolyst Joint Venture in the first quarter provides a strong start to our full-year expectations for our Advanced Materials & Catalysts segment. For Advanced Silicas, we entered the year with an expectation that our polyethylene catalyst sales would continue to outpace global demand growth. However, as global demand for polyethylene may be impacted due to the uncertainty around the economic impact of tariffs, we remain cautious as to the impact on our sales for 2025. Within the Zeolyst Joint Venture, we anticipate significant year-over-year sales growth in 2025, compared to 2024, driven by positive momentum in hydrocracking catalyst sales. We continue to expect the supply and demand imbalance in renewable fuels to challenge near-term sales of our catalyst materials, resulting in an expectation for flat to slightly up year-over-year sales of catalysts used in sustainable fuel production. "We currently believe Ecovyst has minimal direct exposure to the existing tariffs. At this time, we do not expect any first order impact in our Ecoservices segment due to its high U.S. production and sales concentration. For our Advanced Materials & Catalysts segment, we currently anticipate a limited impact on full-year 2025 Adjusted EBITDA of approximately $2 million to $3 million, under the assumption that the existing tariff schedule remains unchanged. Our current full-year outlook does not account for any significant macroeconomic impacts or related demand fluctuations that could result from prolonged tariff uncertainty," said Bitting. The Company's current guidance for full year 2025 is as follows: Sales of $785 million to $845 million1 (change from $755 million to $815 million) Sales of $115 million to $130 million for proportionate 50% share of Zeolyst Joint Venture, which is excluded from GAAP Sales Adjusted EBITDA2 of $238 million to $258 million Adjusted Free Cash Flow2 of $60 million to $80 million Capital expenditures of $80 million to $90 million Interest expense of $47 million to $53 million Depreciation & Amortization Ecovyst - $87 million to $93 million Zeolyst J.V. - $12 million to $14 million Effective tax rate in the mid 20% range Adjusted Net Income2 of $58 million to $85 million, with Adjusted Diluted Income per share of $0.50 to $0.70. The Company's guidance for the second quarter of 2025 is as follows: Adjusted EBITDA2 of $45 million to $55 million 1Sales outlook for 2025 assumes higher average sulfur prices compared to 2024 and higher projected pass-through of sulfur costs of approximately $65 million. 2In reliance upon the unreasonable efforts exemption provided under Item 10(e)(1)(i)(B) of Regulation S-K, 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 (loss) income and net cash provided by operating activities 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. Because this information is uncertain, the Company is unable to address the probable significance of the unavailable information, which could be material to future results. Stock Repurchase Authorization In April 2022, the Company's Board of Directors approved a stock repurchase program authorizing the repurchase of up to $450 million of the Company's outstanding common stock over the next four years. As of March 31, 2025, $229.6 million was available for share repurchases under the program. For possible future repurchases, the actual timing, number, and nature of shares repurchased will depend on a variety of factors, including stock price, trading volume, and general business and market conditions and may be conducted through negotiated transactions, open market repurchases or other means, including through Rule 10b-18 trading plans or accelerated share repurchases. The repurchase program does not obligate the Company to acquire any number of shares in any specific period, or at all, and the repurchase program may be amended, suspended or discontinued at any time at the Company's discretion.

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, Free Cash Flow, Adjusted Free Cash Flow, Adjusted Diluted Income per share, Net Debt to Net Income ratio and Net Debt Leverage Ratio (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 attached appendix. 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 its proportionate share of sales from the Zeolyst Joint Venture accounted for using the equity method as revenue and such sales are not consolidated within its results of operations. However, Adjusted EBITDA for the Company's Advanced Materials & Catalysts segment reflects the Company's 50% portion of the earnings from the Zeolyst Joint Venture that have been recorded as equity in net income in the Company's condensed consolidated statements of (loss) 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.

Because our Advanced Materials & Catalysts segment reflects our 50% portion of the earnings from 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 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 (loss) income related to the remeasurement effects of monetary assets and liabilities, including non-permanent intercompany debt, denominated in foreign currency. (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, effectively reflecting the results as if these inventories were valued using the FIFO 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) Other consists of adjustments for items that are not core to our ongoing business operations. These adjustments include environmental remediation and other legal costs, expenses for capital and franchise taxes, and defined benefit pension and postretirement plan (benefits) costs, for which our obligations are under plans that are frozen. Also included in this amount are adjustments to eliminate the benefit realized in cost of goods sold of the allocation of a portion of the contract manufacturing payments under the five-year agreement with the buyer of the Performance Chemicals business to the financing obligation under the failed sale-leaseback. Included in this line-item are rounding discrepancies that may arise from rounding from dollars (in thousands) to dollars (in millions).

(1) We define Adjusted Net Income as net (loss) income adjusted for non-operating income or expense and the impact of certain non-cash or other items that are included in net (loss) 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 (loss) income or Adjusted Net Income as defined by other companies. The adjustments to net (loss) income are shown net of applicable tax rates of 23.8% and 24.6% for the three months ended March 31, 2025 and 2024, respectively, except for equity-based compensation. The tax effect on equity-based compensation is derived by removing the tax effect of any equity-based compensation expense disallowed as a result of its inclusion within IRC Sec. 162(m), and adding the tax effect of equity-based stock compensation shortfall recorded as a discrete item.

(2) We define Adjusted Free Cash Flow as net cash provided by operating activities less purchases of property, plant and equipment, adjusted for cash flows that are unusual in nature and/or infrequent in occurrence that neither relate to our core business nor reflect the liquidity of our underlying business. Historically these adjustments include proceeds from the 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 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 condensed 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, which is also included in our computation of Adjusted Free Cash Flow.
