Good morning. My name is Nikki, and I will be your conference operator today. Welcome to the Ecovyst Second Quarter 2025 Earnings Call and Webcast. Please note, today's call is being recorded and should run for approximately 1 hour. [Operator Instructions] I would now like to hand the conference over to Gene Shiels, Director of Investor Relations. Please go ahead.

Thank you, operator. Good morning, and welcome to Ecovyst's Second quarter 2025 Earnings Call. With me on the call this morning are Kurt Bitting, Ecovyst's Chief Executive Officer; and Mike Feehan, Ecovyst's Chief Financial Officer. Following our prepared remarks, we'll take your questions. Please note that some of the information we will share today is forward-looking information, including information about the company's financial and operating performance, strategies, our anticipated end-use demand trends and our 2025 financial outlook. This information is subject to risks and uncertainties that could cause the actual results and the implementation of the company's plans to vary materially. Any forward-looking information shared today speaks only as of this date. These risks are discussed in the company's filings with the SEC. Reconciliations of non-GAAP financial measures mentioned in today's call with their corresponding GAAP measures can be found in our earnings release and in presentation materials posted in the Investors section of our website at ecovyst.com. I'll now turn the call over to Kurt.

Thank you, Gene, and good morning. The second quarter of 2025 was another quarter of solid performance for Ecovyst. We achieved our financial objectives, and we delivered on key initiatives that position us for future growth and unlock value for our stockholders. During the quarter, demand fundamentals across the majority of the end uses we serve remained stable. Ecoservices sales were up 14% compared to the second quarter of 2024 with favorable pricing and the addition of the Waggaman site contributing to the increase. Results for our Advanced Materials and Catalysts segment came in favorable to our expectations and our guidance range, reflecting favorable sales timing and mix. In terms of strategic objectives, during the quarter, we closed the acquisition of the sulfuric acid production assets of Cornerstone Chemical Company. Integration of the Waggaman, Louisiana site is ongoing, and we expect to realize meaningful synergies and benefits upon full integration of the site into our existing network. The Waggaman site positions us well to meet the growth needs of our customers, and I want to publicly welcome the enthusiastic and engaged Waggaman team to Ecovyst. Additionally, with our focus on delivering value for our stockholders, during the second quarter, we also repurchased 2.9 million shares of our common stock, totaling approximately $22 million. As is our usual practice, on Slide 6, we provide our latest views on demand trends and our short and longer-term outlook. As I noted earlier, demand fundamentals over the course of the second quarter were stable, and we continue to expect relative stability over the balance of the year. For Ecoservices, high refinery utilization and positive alkylate economics continue to underpin demand for our regeneration services business. We believe the outlook for virgin sulfuric acid demand also remains positive. We continue to expect a stronger second…

Thank you, Kurt. Good morning. As a follow-up to our stronger-than-anticipated results in the first quarter, we exceeded our financial targets for the second quarter, providing for strong momentum as we move into the second half of the year. Our second quarter adjusted EBITDA was just under $56 million, coming in above the high end of our guidance range. Although unplanned and extended customer outages in the second quarter adversely affected sales volume for regeneration services, Ecoservices landed within the midpoint of our segment guidance range. For our Advanced Materials and Catalysts segment, favorable sales timing and mix helped drive more favorable results in the quarter compared to our. As we look to Slide 9, I'll highlight the major components of the period-over-period change in adjusted EBITDA. Pricing, excluding the pass-through of higher sulfur costs, increased quarter-over-quarter, reflecting favorable contractual pricing for regeneration services and strong pricing for virgin sulfuric acid. The pass-through effect of higher average sulfur costs on sales was approximately $20 million, with the pass-through resulting in no material impact to adjusted EBITDA. Variable costs were favorable on product mix. Volume and customer mix were unfavorable during the quarter, driven by lower event-driven niche custom catalyst sales in advanced silicas, along with unplanned and extended customer downtime within Ecoservices, partially offset by the sales volume contribution from the Waggaman sulfuric acid assets. The remaining other component primarily represents higher manufacturing costs in Ecoservices, driven by general inflation and additional costs associated with the Waggaman acquisition, partially offset by lower turnaround costs. As we turn to our segment results on Page 10, I'll begin with a summary of the second quarter results for Ecoservices. Ecoservices sales were $176 million, up $22 million compared to the prior year. The higher sales reflect the $20 million pass-through effect of higher…

Thank you, Mike. 2025 continues to provide a challenging operating environment for our industry with companies in our sector facing issues that include global production overcapacity, pricing and margin pressures, and disruption related to the evolving tariff landscape. In this environment, Ecovyst has demonstrated consistent performance. Our strong results in the first half of 2025 underscore the resilience of our distinctive businesses, which we attribute to our leading supply positions, long-standing customer relationships, diverse geographic footprint and a portfolio of technologies that are highly valued by our customers. As we continue to move into the second half of the year, we have good momentum that we believe positions us well to deliver on our full year financial objectives. We expect high refinery utilization will continue to benefit our regeneration services business and that tailwinds and incremental demand in the mining sector will provide support for virgin sulfuric acid sales for the balance of the year. Within our Advanced Materials and Catalysts segment, we anticipate strong sales performance for hydrocracking catalysts in 2025, with projected sales exceeding those of 2024. This positive outlook is underpinned by a substantial order book and confirmed orders. We also continue to expect growth in our sales of polyethylene catalysts and supports, and we expect sales of catalysts used for sustainable fuel production to be flat to slightly up in 2025. Looking ahead, Ecovyst is well positioned to benefit from prevailing trends such as the onshoring of manufacturing, the increased need for clean fuels and growing mining operations for metals and minerals. We believe that our differentiated customer relationships and technological capabilities will enable us to translate the positive long-term sector momentum into steady growth. Ecovyst's robust cash flow and resilient business model also enable us to further create value for our shareholders through growth investments such as the recent acquisition of the Waggaman plant, as well as by returning capital via share repurchases. Lastly, we acknowledge the significant interest in the strategic review of our Advanced Materials and Catalysts segment. As communicated previously, we anticipate the process may extend through midyear 2025. We are making steady progress and expect to remain on this timeline. We anticipate providing additional updates in the near future. At this time, I will ask the operator to open the line for questions.

[Operator Instructions] We'll take our first question from Patrick Cunningham with Citi.

Just with the new EPA guidelines for increased renewable fuel volume, have you already seen initial indications from customers coming back with additional activity here? I guess, any early indications or visibility into what this might mean for volumes in 2026?

Patrick, thank you for the question. So at this point, it's still early, and those are -- I would say, they're draft -- it's a draft RVO, so it has to be fully adopted. But we are certainly encouraged by the new requirements that were set. I mean, it's -- as I said in my comments, a 67% increase year-over-year from '25 to '26, we feel that really is going to drive utilization. There's -- one of the issues that the industry has had in the last 12 months or so has been underutilization just with the low RIN credits and the uncertainty around the RVO. So pushing that RVO up should drive higher utilizations in 2026, which then should lead to higher utilization of catalysts, more change-outs and eventually, additional capacity being put online. So we're pretty positive in terms of the direction that it's headed.

Understood. And then, maybe just on potential outlook for polyethylene sales here, it seemed to have a mixed view with strong sales expectation, but there's some incremental caution on the trade uncertainty. How much of your year-on-year growth is tied to start- ups? And have you heard any noise on potential delays in production or pressure on operating rates as a result of the current trade environment?

No. I mean, clearly, polyethylene utilization rates have been impacted across the globe with the tariff uncertainty and, I'd say, the lackluster global macroeconomic environment, and some of that is -- and there's some overcapacity in China that still weighs on the polyethylene industry. We still expect our sales to be up year-over-year, albeit probably falling short of what we had thought earlier this year. And obviously, in our AMAC segment, as we mentioned, that's being overcompensated by stronger hydrocracking and specialty catalyst sales. So we're cautious. I wouldn't say our sales this year aren't necessarily for new units, just our run rate with our existing customers. We are continuing with our Kansas City expansion that -- we're expecting those customers that are going to take the offtake of that plant or that plant expansion to come online in 2026.

Our next question comes from John McNulty with BMO Capital Markets.

So, now that you've finalized or settled on the Cornerstone business, I guess, any update in terms of how you're thinking about some of these synergies come through and the earnings opportunities, say, in 2026? I know this year, there's some integration and some costs of upgrading, et cetera. But I guess, how do you think about the contribution as we look out a year?

Yes, John, thanks for the question. As we mentioned, this year, we believe that we are going to see additional sales, of course, coming out of the acquisition, albeit kind of offset with some additional costs that we're incurring really to get that business up and running into our level of operations. For next year, we're not going to give directional or specific guidance yet, but we do believe that it is a very good acquisition for us, allowing for additional opportunities within the Gulf Coast, among the other plants that we serve, to help serve some of our customers, along with the new customers that we see. The integration of the plant is going very well. We see opportunities both at the plant locations to improve what we see there, along with looking at opportunities at our other plants as well. We also do see additional opportunities from a spot standpoint within the virgin sulfuric acid that will help us in next year as well.

Got it. Okay. Fair enough. And then, I guess, you had mentioned early on that you've got some new areas where you're doing some trials, and it looks like some of that may materialize as you look into 2026. I guess, can you give us a little bit of color as to what those trials or those pilot programs are really focused on at this point? I know you had a bunch kind of in the hopper.

Yes. That's primarily -- I'd say, in the AMAC segment, we talk about biocatalysis. There's been a lot of interest in that area. That's obviously growing very rapidly. And the interest in using silicas as a carrier for the enzymes continues to be -- draw a lot of interest. So we've been working with a lot of customers, signing joint development agreements and so forth, working with them to get those products spec-ed in. And I would point to advanced recycling also, their customer taking pilot samples of our catalysts that are obviously used in advanced recycling that help lower the energy intensity of that process and improve the [indiscernible] product. So there's been good interest around that as well.

Our next question comes from David Begleiter with Deutsche Bank.

Kurt and Mike, just on the strategic review, can you remind us what you -- the process you're going through, what you're looking at, and what are the various options on the table for this business and these assets?

Yes. So the -- as we stated, as the Board -- thank you, Dave, for the question. As we stated last year, the review is really looking at a full spectrum of options to deliver really what we think is the most value for our shareholders in relation to the AMAC business, which -- that could be a whole bunch of different types of options. Like we said on the call, that -- we're happy with where the progress is at. We're still moving forward with it, and we should have some further details on it in the near future.

Got it. And just on leverage, given the uptick in the quarter, when would you expect to get to your leverage target, assuming no M&A or other asset dispositions?

Yes. No, we definitely saw an uptick on the leverage up to 3.5x, but that was primarily due to the acquisition of the Waggaman location, along with some of the share repurchase activities, right? But if you look at our free cash flow target for the rest of the year, our expectations for the remainder of the year, the leverage ratio will come down clearly into the range that we expected for the year, likely around a 3x leverage. We're still targeting long term to be in the 2x to 2.5x range. However, we do want to ensure that we take every dollar that we're making, put it back into organic growth opportunities. And then, with the level of where our stock price is trading and the intrinsic value and long-term growth potential of the business, we still see share repurchase as an opportunistic way to create shareholder value in the future. And then, with the acquisition of the Waggaman location, we continue to see if there's options for additional bolt-on opportunities in the future.

Our next question comes from Aleksey Yefremov with KeyBanc Capital Markets.

I just wanted to follow up on the biofuels. Assuming the current proposal was approved in its current shape, right, so about 67%, as you said, RVO growth next year, how should we think about sensitivity of your business to that growth? I mean, over time, should your catalysts business also grow in that same range by, I don't know, 60%, 70%, or should it be some smaller or larger number?

Yes. Thanks for the question, Aleksey. I think the way I would look at the RVO is really, the proposed RVO changes is really reinjecting momentum back into the renewable fuels, which has stepped back, I would say, over the last 12 months with really overcapacity and lower RIN prices. So we believe that, that increased RVO is going to drive up the utilization, which will eventually lead to more frequent catalyst changeouts and additional capacity coming online. I don't think the 67% is going to be a year-over-year step change for our business. Already, we've seen the business -- we believe that we're going to be flat to slightly up for this year. So we've seen, I would say, a stabilization of that. But we do think long term, with that additional -- that additional RVO will create some momentum and clearly translate into growth in that segment for us, but not -- I wouldn't look at the instantaneous year-over-year and try to apply that to our growth rate for any short period of time.

And on sulfuric acid, I think you're baking in some pickup in nylon later this year. And I know [indiscernible] on maybe getting a little too optimistic there. So [indiscernible] how much visibility do you have? And also, any outlook for sort of mining, nylon, these industrial uses next year and -- for virgin sulfuric acid?

Sure. It's just on nylon, and re-ask the question if I don't answer it. You broke up a little bit on the first part of the nylon segment. But our view on nylon this year, Aleksey, I think is, we are going to be up year-over-year in that space, albeit it remains a somewhat tepid year in that industry. I mean, that's obviously widely reported, the global nylon market remains oversupplied. Where we're positioned, where our customers are positioned, particularly in the Gulf Coast, they've got some -- obviously some advantages over the rest of the world on a cost basis. So I think they benefit a little bit from that. So for us, our virgin sulfuric, we believe it's going to be up year- over-year, albeit not -- certainly not a bumper year or anything along those lines. For mining, there's tremendous momentum in mining. There's new copper projects coming online this year, which we're going to participate in. All the mines -- and I'm sure you've read the headlines, there's multiple new mines being approved. And that's really being driven by the -- I wouldn't point to the tariffs, but the need for copper for data transmission, for electrical conductivity, all related to the data centers that are being built and all the needs for electrification and green energy and so forth. So we view long- term mining remains very, very positive, and we expect to have a stronger second half in mining as some of those new projects come online.

[Operator Instructions] We will move next with Hamed Khorsand with BWS Financial.

About Waggaman, it sounds like you're still putting some investments in there. Do you have a timeline as to when it would actually contribute to free cash flow?

I mean, the free cash flow generation will follow the earnings, right? So we don't expect a significant amount of free cash flow to be generated this year. However, certainly, with the synergies and the acquisition and the size of it, we expect it to generate positively in 2026.

Okay. And then, are you -- do you have any pricing power at all in the sulfuric acid for mining that you're talking about?

Yes. I think our mining agreements, Hamed, are generally -- they're not spot in nature. They're longer term, not super long term, but there are pricing mechanisms in those where demand goes up, actually, the pricing can go up as well. So I would just say the overall momentum in mining and the demand for the sulfuric acid that's coming from that sector rising and rising is just kind of the tide that's lifting all boats. So it's creating positive momentum across the industry for sulfuric acid pricing.

And our next question comes from [ Laurent Alexandre with Kaiser ].

Could you give a little bit more detail on the order timing and how -- what issues and what that might imply for the rhythm of 2026? And then, secondly, can you talk a little bit about the polyethylene catalyst? As capacity shuts in Europe and as you get newer plants built in Asia, is there any change in your revenue per ton of capacity? Is one better for you than the other?

Yes. Thanks for the question. On the first one, from an order timing standpoint, the order timing that we saw earlier in the year is expected to just shift from part of the latter part of the year. So we don't expect that to be materially different for next year. We do see higher expected sales of hydrocracking catalysts this year, and that's just demand driven. So the timing that we've been discussing for the first half of the year is just between second half and first half. So no impact on 2026.

Yes. Thank you for the question, [ Laurent ]. Really, polyethylene, as you point out, there's clearly capacity being rationalized in Europe. That's generally a pretty small exposure for us in terms of our customer base. And where we see the growth, and as we refer to you, the Kansas City expansion, those are based on projects for North America and the Middle East. So there's really -- I don't think there's really a huge difference in terms of revenue per ton or anything. It's just more the volumetric demand coming from those new sites is obviously going to pull up our sales and volume of sales into polyethylene catalysts and supports.

And we have no further questions in queue at this time. This does conclude the Ecovyst Second Quarter 2025 Earnings Call and Webcast. Thank you for your participation, and you may disconnect at any time.
