“Given the challenging and evolving macroeconomic environment, we are pleased with Ecovyst’s results for the third quarter of 2023 as they reflect positive pricing and stable demand fundamentals across the majority of our end uses. In our Ecoservices segment, high refinery utilization during the quarter continued to provide support for regeneration demand. As anticipated, virgin sulfuric acid sales volume was lower compared to third quarter 2022 levels, primarily due to lower end use demand for virgin sulfuric acid into the production of nylon intermediates, while sulfuric acid demand for other end uses remained stable,” said Kurt J. Bitting, Ecovyst’s Chief Executive Officer. “Within our Catalyst Technologies business, we saw stronger sales of hydrocracking catalysts and higher sales of catalysts into renewable fuel applications, while weaker global polyethylene demand and destocking resulted in lower sales of silica catalysts compared to the year-ago quarter,” said Bitting. “As a result, third quarter Adjusted EBITDA was $68 million. Adjusted EBITDA was lower compared to the third quarter of 2022 largely due to lower sales volume for virgin sulfuric acid and polyethylene catalysts, as well as higher manufacturing costs associated with the July maintenance outage that resolved the production restriction at our Dominguez plant. Of note, overall profitability remained favorable, as evidenced by a third quarter Adjusted EBITDA margin of 32.3% that was up 330 basis points compared to the third quarter of 2022.”

Sales for the quarter ended September 30, 2023 were $173.3 million, compared to $232.5 million in the third quarter of 2022. The change was primarily driven by a $39 million impact associated with the pass-through of lower average sulfur costs compared to the third quarter of 2022. In addition, virgin sulfuric acid sales volume decreased, primarily due to lower end use demand for virgin sulfuric acid used in the production of nylon intermediates, while silica catalyst sales reflected lower end use demand for polyethylene catalysts and the absence of niche-custom catalyst sales, compared to the third quarter of 2022. Within the Zeolyst Joint Venture, sales were higher on increased sales of hydrocracking catalysts and catalysts used in the production of renewable fuels.

Net income was $16.6 million, compared to net income of $21.3 million in the third quarter of 2022, with a diluted net income per share of $0.14. Adjusted net income was $22.2 million with an Adjusted diluted earnings per share of $0.19. Adjusted EBITDA was $67.9 million, compared to $75.4 million in the third quarter of 2022, with the change reflecting lower sales volume and higher costs associated with increased maintenance and networking costs arising from production downtime in July at our Dominguez site, partially offset by higher pricing.

While third quarter 2023 sales volume for virgin sulfuric acid into the nylon end use and sales of polyethylene catalysts were lower than in the third quarter of 2022, as anticipated, demand for the balance of our product portfolio remained stable. During the quarter, high refinery utilization continued to support demand for regeneration services. Compared to the third quarter of 2022, we also saw stronger demand for hydrocracking catalysts and for catalysts used in renewable fuel production, and we continue to expect strong sales of hydrocracking catalysts to continue in the fourth quarter.

As previously disclosed, late in the second quarter of 2023, we saw evidence of weaker demand fundamentals in nylon and polyethylene end uses, which we believe are primarily driven by cyclical, global demand trends. We believe these weaker demand fundamentals will continue for the balance of 2023. We expect virgin sulfuric sales into nylon applications to continue to be impacted by weaker demand in the fourth quarter of 2023, including from the adverse impact of the UAW strike on vehicle production, in which nylon is used for light weighting materials used in automobiles. We also expect lower sales of polyethylene catalysts to continue in the fourth quarter of 2023, due to the impacts of destocking and lower polyethylene production plant operating rates.

Our regeneration services support the production of alkylate, a high value gasoline component critical for meeting stringent gasoline standards and for producing premium grade gasoline. More stringent gasoline standards and increasing demand for higher-octane premium fuels used in high compression, more fuel efficient engines resulted in higher utilization for our customers’ alkylation units. High U.S. refinery utilization through the first nine months of 2023 supported our customers’ production of alkylate and translated into strong demand for our regeneration services. We expect refinery utilization to remain high into 2024, with lower utilization in the fourth quarter of 2023 associated with our customers’ planned turnaround activity. Sulfuric acid is a widely used chemical and it plays a key role in producing a wide array of materials, particularly those supporting green infrastructure. We expect our virgin sulfuric acid sales to continue to benefit from mining activity for metals and minerals that provide conductivity in low carbon technologies, as well as from demand in a wide range of industrial applications. Our catalyst activation services provide for ex-situ sulfiding and pre-activation for hydro-processing catalysts, with expected demand growth in both traditional and renewable fuel production. We believe sustainability trends will continue to translate into favorable demand for our treatment services business as customers seek the sustainability-focused waste solutions offered by Ecoservices.

Third quarter sales were $147.6 million, compared to $195.7 million in the third quarter of 2022. The change in sales reflects lower pass-through of sulfur costs of approximately $39 million, as well as lower virgin sulfuric acid sales volume, primarily into the production of nylon intermediates. Adjusted EBITDA was $54.7 million, compared to $64.1 million in the third quarter of 2022. The decrease reflects lower virgin sulfuric acid sales volume and higher costs associated with increased maintenance and higher networking costs arising from production downtime in July at our Dominguez site.

Our silica catalysts business supplies critical catalyst components for the production of high-density polyethylene, a high-strength and high-stiffness plastic used in bottles, containers, and molded applications and linear low-density polyethylene used predominately for films. While we expect long-term demand for polyethylene films and packaging to remain positive, late in the second quarter we saw evidence of softer global demand and lower operating rates for polyethylene producers, which resulted in lower sales during the third quarter, and which are expected to impact sales for the balance of 2023. Earlier in the quarter we announced a planned expansion of our silica catalyst production capability at our Kansas City, KS, facility to support projected growth in demand for polyethylene production, backed by long-term customer commitments, with an anticipated completion date in late 2025. Through the Zeolyst Joint Venture, we also supply specialty catalysts to customers for use in the production of both traditional and renewable fuels, petrochemicals, and emission control systems for both on-road and non-road diesel engines. While demand for traditional fuels remained positive, demand for renewable fuels also increased.

During the third quarter of 2023, silica catalysts sales were $25.7 million, compared to $36.8 million in the third quarter of 2022, with the change reflecting lower sales of polyethylene catalysts associated with destocking and lower customer operating rates and the absence of event-driven, niche-custom catalyst sales compared to the third quarter of 2022, partially offset by higher average selling prices. The Zeolyst Joint Venture sales were $37.0 million, up 33.1%, compared to $27.8 million in the third quarter of 2022. The increase in sales was due to higher sales of hydrocracking catalysts and higher sales of catalysts used in renewable fuel production. Adjusted EBITDA, which includes the Zeolyst Joint Venture, was $16.4 million, compared to $19.3 million in the third quarter of 2022, with the change reflecting lower sales of silica-based catalysts, partially offset by the impact of higher sales in the Zeolyst Joint Venture and higher pricing.

Cash flows from operating activities was $73.4 million for the nine months ended September 30, 2023, compared to $109.3 million for the nine months ended September 30, 2022. The decrease was primarily driven by the timing of dividends received from the Zeolyst Joint Venture. At September 30, 2023, the Company had cash and cash equivalents of $38.3 million, total gross debt of $879.8 million and availability under the ABL facility of $70.8 million, after giving effect to $4.0 million of outstanding letters of credit and no revolving credit facility borrowings outstanding, for total available liquidity of $109.1 million. The net debt to net income ratio was 13.4x as of September 30, 2023 and the net debt leverage ratio was 3.2x as of September 30, 2023.

“Within Ecoservices, our expectation for regeneration services demand in the fourth quarter remains unchanged; however, similar to past years, we expect lower regeneration volume in the fourth quarter of 2023 as our refining customers conduct their customary, seasonal turnaround activity. We expect virgin sulfuric acid sales into the production of nylon intermediates to reflect incremental pressure, arising from the UAW strike and its impact on vehicle production, where nylon is widely used for light weighting materials used in automobiles. In light of this softer expected demand for virgin sulfuric acid in the fourth quarter, we have elected to accelerate a turnaround originally scheduled for 2024 into 2023. The turnaround is expected to result in higher costs, and we anticipate it will have a modest impact on virgin sulfuric acid production and sales for the balance of 2023. However, we believe the acceleration of this turnaround will position us well to capture volume recovery in 2024,” said Bitting. “For Catalyst Technologies, in the fourth quarter we continue to expect higher sales of hydrocracking catalysts, compared to the fourth quarter of 2022.”

“We see the potential for further macroeconomic deterioration and incremental year-end destocking in the fourth quarter. Given weaker demand for virgin sulfuric acid sales into nylon intermediates in the fourth quarter, lower expected sales for polyethylene catalysts, and the incremental costs to be incurred by the accelerated turnaround in Ecoservices, we now expect full-year 2023 Adjusted EBITDA to be at the low end of our previous guidance range, at approximately $260 million,” added Bitting. “In addition, we are revising our cash generation expectations for the full-year 2023. We now expect to generate $70 million to $80 million of Adjusted Free Cash Flow, with the reduction from prior expectations primarily driven by the timing of dividends from our Zeolyst Joint Venture. The lower expected dividends in 2023 are associated with higher working capital needs within the joint venture at the end of 2023. As we expect strong hydrocracking catalyst sales in the fourth quarter, the revised working capital expectation reflects typical timing of receivable collections as well as inventory build needs in advance of strong expected sales of hydrocracking catalysts in the first quarter of 2024. We anticipate that the working capital increases in the Zeolyst Joint Venture will provide a comparative free cash flow benefit in 2024.”

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 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. 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.

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. To date, repurchases under the program have been funded using cash on hand and cash generated from operations, with repurchases conducted through negotiated transactions with the Company’s equity sponsors, as well as through open market repurchases. Future repurchases may also be conducted through negotiated transactions with an equity sponsor, open market repurchases or other means, including through Rule 10b-18 trading plans or through the use of other techniques such as accelerated share repurchases.

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. 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. As of September 30, 2023, $234.6 million was available for additional share repurchases under the program.

We have two uniquely positioned specialty businesses: Ecoservices provides sulfuric acid recycling to the North American refining industry for the production of alkylate and provides on-purpose virgin sulfuric acid for water treatment, mining, and industrial applications; and Catalyst Technologies provides finished silica catalysts and catalyst supports necessary to produce high strength and high stiffness plastics and, through its Zeolyst Joint Venture, supplies zeolites used for catalysts that help produce renewable fuels, remove nitrogen oxides from diesel engine emissions as well as sulfur from fuels during the refining process. For more information, see our website at https://www.ecovyst.com.

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 earnings per share, 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 appendix below.

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.

(1)We define adjusted net income as net income 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.

The adjustments to net income are shown net of applicable tax rates of 27.4% and 27.7% for the nine months ended September 30, 2023 and 2022, respectively, except for the foreign currency exchange (gain) loss and 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. The tax effect of the foreign currency exchange (gain) loss is derived from tax effecting the actual year to date foreign currency exchange (gain) loss by the respective local country statutory rates which is 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 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.
