Thank you, Gene, and good morning. Overall, we are very pleased with our fourth quarter results and the execution of our strategic objectives. Regeneration services contributed to a solid quarter. In terms of financial results, the fourth quarter was also a significant quarter in the context of our ongoing portfolio transformation. We completed the divestiture of the Advanced Materials and Catalysts segment earlier than expected for a sales price of $556 million, utilizing $465 million of the net proceeds to pay down our term loan, leading to a net debt leverage ratio of 1.2x at year end. This transaction has transformed the company, initiating a new focus to drive progress by delivering reliable sulfur solutions for clean fuels and critical materials. In 2025, we began executing on our capital allocation strategy with the acquisition of the Wagaman sulfuric acid assets for approximately $40 million and repurchased just under $50 million of common stock. We enter 2026 with a strong balance sheet and significant liquidity that we believe positions us well to continue our capital allocation priorities directed at growth, both organic and inorganic, and the continued return of capital to our stockholders. Turning to the demand trends on slide five, our demand outlook for 2026 remains positive, underpinning the volumetric growth we anticipate. We expect favorable contractual pricing for regenerated sulfuric acid and stable pricing for virgin sulfuric acid. In 2025, U.S. refineries underwent extensive maintenance, including our customers. This year, we expect our refining customers to run at high utilization, benefiting from favorable alkylate economics. With less planned customer downtime than in 2025, we anticipate higher sales for our regeneration services in 2026. We are also anticipating higher sales of virgin sulfuric acid in 2026, with demand growing in mining, which accounts for 20% to 25% of our sulfuric…

Thank you, Kurt, and good morning. We closed out the year with a solid financial performance in the fourth quarter. Delivering full-year adjusted EBITDA of $172 million, ahead of our previously provided guidance. As a reminder, with the divestiture of the Advanced Materials and Catalysts segment, the results for the business are reported in discontinued operations for all periods. My comments this morning pertain to the reported results from continuing operations. Our strong fourth quarter results were driven by continued sales growth in both volume and pricing, resulting in adjusted EBITDA of $51 million, 8% ahead of the prior year. We generated $78 million of free cash flow, of which we used $20 million in the fourth quarter for share repurchases. And with the proceeds from the sale of the Advanced Materials and Catalysts business, we paid down $465 million of our term loan, resulting in a 1.2x net leverage ratio, leaving $265 million of available liquidity. Diving a bit deeper into the numbers, fourth quarter sales were $199 million, up $51 million, or 34%. Excluding the $28 million impact of higher sulfur cost pass-through in price, sales were up 15%. However, this was more than offset by higher sales of virgin sulfuric acid, including the contribution from the acquired Wagaman assets, and favorable contractual pricing for regeneration services, partially offset by higher planned fixed manufacturing costs, including incremental costs of the acquired Wagaman assets, and by unplanned and extended customer downtime. The 8% increase in adjusted EBITDA for the fourth quarter reflects the favorable volume and price impact at the sales level and favorable contractual pricing for regeneration services. While the adjusted EBITDA margin decreased 630 basis points compared to 2024, this reduction primarily reflects a significant increase in sulfur costs, which we passed through with no material impact…

Thank you, Mike. We are extremely pleased with our progress in 2025, and I want to thank my Ecovyst Inc. colleagues for their efforts in supporting our customers, delivering on our commercial objectives, and for their contributions as we continue to implement our strategic plan. In a challenging demand environment, our business demonstrated resilience in 2025. Sales of virgin sulfuric acid increased, in part driven by the acquisition of our Wagaman sulfuric acid assets. As the integration of the Wagaman site continues, we are benefiting from the positive network effect Wagaman’s assets have on the reach and capability of our supply chain. In terms of demand driven by high refinery utilization, the favorable business fundamentals of our regeneration services business remain unchanged. Although our regeneration services business was adversely affected by a significant number of unplanned and extended customer outages in 2025, in 2026, we are expecting growth for both our virgin sulfuric acid sales and the value represented by alkylate economics for our regeneration services business. With stable pricing expected for virgin sulfuric acid and continued positive contractual pricing for regeneration services, we look beyond 2026 and believe the demand outlook remains positive for all of our businesses. The divestiture of the Advanced Materials and Catalysts business at year end represents a transformative event in our ongoing portfolio optimization. As we move forward, driving growth for the eco services platform, we will do so with a more stable and predictable business profile, a significantly strengthened balance sheet, and with a cash generation capability and liquidity position that we anticipate will provide for significant capital allocation flexibility. This year, we are increasing our capital budget to support targeted organic growth projects that we expect to strengthen our service offering for mining clients. Key initiatives include expanding Gulf Coast storage and optimizing logistics, which will strengthen our service offering. These projects are scheduled for completion in 2027. In 2025, we repurchased approximately $50 million in common stock, and during 2026, we plan to continue this strategy with additional repurchases totaling between $25 million and $40 million. We plan to take a disciplined approach towards inorganic growth, prioritizing accretive acquisitions that extend our reach to customers and end segments. Concurrently, we remain committed to returning capital to stockholders through an active share repurchase program. In summary, our focus this year will remain on driving profitable growth, positioning Ecovyst Inc. for future opportunities, and optimizing value for the benefit of our stockholders. At this time, I will ask the operator to open the line for questions.

Thank you, Mr. Bitting. Ladies and gentlemen, at this time, if you do have a question, please press. We will go first today to John Patrick McNulty of BMO Capital Markets.

Yes, good morning. Thanks for taking my question and congratulations on a solid year. Just wanted to dig into the Wagaman opportunities a little bit more. So you have had the asset for a bit of time, you have made some investments in it. I guess, can you help us to think about how much capacity that has freed up for you and as a result, how much growth you could necessarily get without having to put in much capacity or incremental capacity? Because it sounds like you are even further trying to unlock some flexibility with the storage increase and the rail increase. So I guess, can you help us to contextualize all this?

Sure. Thanks, John. So the Wagaman sulfuric acid assets that we added last year, of course, added roughly around 10% of volume to the overall network. It came along with its own customer book and sales, which we are obviously servicing. We are really seeing the positive network effect. It is a force multiplier with our Gulf Coast network where all the sites now can back each other up in terms of turnarounds and so forth, and enable themselves to take advantage of additional opportunities that they may have had to pass on if they were on their own. It fills the cracks in terms of the supply network and allows us to take advantage of more opportunities. It also is our only site that has a deepwater vessel dock. We actually did export a ship of sulfuric acid there. It adds a lot of capability to our overall site. As we move forward, the way we look at our Gulf Coast network and the investments that we are making, we clearly want to focus the Houston production more to the West. We are making additional investments that we talked about on our logistics and storage capabilities, which are going to be Houston-based to service more of the Gulf Coast assets with that plant, and the Wagaman assets and the production that that brings allows capacity into our Gulf Coast system, enables us to further service that and take advantage of the rising tide on the mining demand. Does that make sense?

Yes, completely. That definitely helps. And then, I guess, on the regen contract pricing, can you help us to quantify that a little bit? It sounds like you were getting some benefits in 2025. It sounds like that is a continual kind of repricing, but how should we think about the lift in 2026?

Yes, John, thanks for the question. Yes, it is going to be a similar lift. I think, as we have talked in the past, every year the contractual agreements that we have start to roll off. It is usually between 15% to 20% a year; it just depends on the size of the customers and how they shape up. With basic costs going up, with the inflation and how the contracts are structured, with indexing and other factors, it does provide a benefit. So it is a continued benefit similar to what we saw this year. That is going to extend into next year, and again, it just depends on timing of when some of those customer contracts come up and when they are put in place.

Thanks very much for the color. Just regarding the weakness that you are citing in industrial applications—nylon, obviously, we have seen some pretty promising indicators with U.S. PMI inflecting, maybe nylon bottoming out—but are there any specific applications that you want to call out or factors that you would highlight, which is giving you some caution here?

Patrick, thank you for the question. Our basket of what we call industrial uses spans a very wide spectrum. As you know, sulfuric acid is the most widely used chemical in the world, and there is anything from core alkali production to nylon to other petrochemicals. There are a lot of different things and a lot of different drivers there. We just see some caution in some of those areas. I do not think it is over-caution or a real worry. We service such a wide and diverse basket of folks there that could be impacted by any of the global things going on between tariffs or some of the downturns in some of the chemical end markets. For us, our biggest one is, as you referred to, nylon. As we have clearly pointed out, we expect to be roughly on par with where we were in 2025, so we do not really project any degradation there.

Thank you. We will go next now to Patrick David Cunningham of Citi.

Hi, good morning. On a go-forward basis, as you think about CapEx or acquisition multiples, how do the economics of greenfield versus debottlenecking compare to current existing virgin facilities? It seems like there is a lot you may want to do or need to do to meet long-term mining demand.

Yes. That is a great question. I think with the way we have treated our sites over the past, I would say, 10 or 15 years, the demand from the mining sector has risen, and we are going to continue to do that—debottlenecking in our sites from both the production standpoint as well as the logistics standpoint. As that rising tide happens with mining, we are able to stay ahead of it by making the logistics and storage investments that we just talked about. We have got some additional debottlenecking that we can do. We can leverage more of Wagaman’s production into our Gulf Coast system, and we are going to continue that pattern, enabling us to stay ahead of the demand and further service that.

Thank you. We will go next now to Aleksey V. Yefremov of KeyBanc Capital Markets.

Thanks. Good morning, everyone. I just wanted to follow up on the same subject. The expansion that you are undertaking in 2026, is it tied to any specific ramp at your customers in mining or elsewhere that you anticipate? In other words, do you have contracts or some sort of indication from your customers that they will need additional volumes for sulfuric acid, specifically as it relates to copper?

We have long-term relationships with those customers, and we are confident that the demand will be there. It is a mixed bag of what is driving that additional demand—there are actually some new projects that have come online, and there is also additional demand from existing mines. We have been servicing a lot of these mines. So we feel it is appropriate for us to add this additional capacity. We have the logistics capacity to meet that growing demand long term, coming from our plants in the Gulf Coast.

And as a follow-up, how would you characterize the current state of the merchant acid market either right now or if you have a view on 2026—is the market sort of long, tight, or about balanced from a supply-demand perspective?

Thanks for the question. I would say it is in a balanced position. In our call, we talked about pricing being stable. I would say it is leaning towards a balanced market, however, there are certain segments of the market that are all over the board in terms of the different end-use applications. Some of those are up, some of those may be down. On the whole, our view at this point is a push in general. Other sectors that use sulfuric, like mining, are obviously rising. The long-term trend, certainly as you look at things like mining, is growing demand there.

We will go next now to David L. Begleiter with Deutsche Bank.

Thank you. Good morning. Kurt, on your full-year guidance, the low end looks maybe a little conservative. What would you need to see to get the low end of the range? And conversely, what type of drivers would you expect to see to get to the high end or above that range for the year?

Thank you for the question. Starting at the high end of the range, if there is a lift in things like virgin acid pricing that comes about because of demand growing and it putting upward pressure on pricing in the virgin sulfuric acid market, that would help. Our outlook on regeneration, as we talked about, is expected to run at pretty high utilization. We expect a pretty healthy year in terms of regeneration. I do not think there is going to be tremendous movement on that because that is a stable, contracted business, and we do not expect spot volumes that become available. On the low end, it would largely be driven by things like unplanned customer outages similar to what we had last year, or potentially a macroeconomic event that causes a deterioration in either pricing or volumes on virgin sulfuric acid. Conversely, if there is some positivity and pricing, or spot, we could trend toward the upper end.

Very clear. And, Kurt, now with the balance sheet restored to strength, how do you see Ecovyst Inc. in three to five years? What do you want to be? Where do you want to go? From an inorganic standpoint, in terms of M&A, what could be additive to the portfolio that you are looking at today or maybe down the road?

Thanks for the question. The Board and the management team are carefully looking at our capital priorities as we focus on maximizing the value for our shareholders over the long run. Number one, we see opportunities in front of us in mining and other spaces. That is going to entail us investing in organic growth as we see the demand for sulfuric acid and the sulfur molecule grow. We want to make investments there and continue to be a leading supplier in that space, so we can further service our existing customers or existing industries that we service in a better way. Number two, growth through sensible and accretive acquisitions—accretive bolt-on acquisitions that make sense that are either adjacent to us from a chemistry standpoint or a service standpoint—to become bigger. And finally, as we have talked about with our flexible capital allocation strategy, we still see value in share repurchases as well as a tool. It is a flexible strategy that allows us to push in all three of those directions, which we think can help us drive better value for shareholders over the long run.

Thank you. We will go next now to Hamed Khorsand at BWS Financial.

Hi. Sorry if I missed this, but are you done with the investments you need to make at Wagaman? And in the near future, as you further integrate it, are you able to deliver the sulfuric acid to mining that might be a little bit higher in demand, or are your contracts pretty much fixed on volume?

Thank you for the question. Good to talk to you, Hamed. The integration is going well. We talked about it—It has had a positive network effect on our ability to supply our customers in the Gulf Coast. We have owned the site now for about nine months. The site is going to have a maintenance outage this quarter. There are still some additional investments that we want to make in the near future as we further integrate it and try to raise the operating rate on the location. From an operating and integration standpoint, there will be some investments made, and we expect that there will be further investments necessary if the nylon or industrial end markets are as weak as you are expecting. As we have talked about before, and I know people have followed the company, most of our virgin sulfuric acid business is not 100% supply contracts. We have very close relationships with our customers. They provide us great and accurate forecasts into what they are going to do, not only in mining but in some of the other sectors in terms of industrial. That helps us plan as we look at our year and say where we are going to place our volume. If there is a downturn or something unexpected, we do have the ability to place some additional product into different end-use segments and move things around—probably not all of it, but some portion thereof—whether it is into mining or other industrial segments that may be in the Gulf Coast. We have some flexibility to move around net volumes.

We will go next now to Laurence Alexander of Jefferies.

Good morning. Just can you give a higher-level view on your M&A opportunity set? When you look at the landscape in terms of other assets producing sulfuric acid, is there any titration in terms of the quality of the assets? Can you separate out the market in terms of the addressable versus the assets that you would just not like—is it 30% to 40% of the market that you would have no interest in? Or is it potentially all of interest?

Thanks for the question. We would generally be interested in all those types of assets because we would have use for both since we are a leader in both spaces. We are pretty broad in terms of our sulfuric acid and the end uses we service. We service a wide swath of the market. We are not just a regeneration sulfuric acid producer or just a virgin sulfuric acid producer like some of the others out there. I would also say that extends to other exposure in terms of making sulfur derivatives for water treatment or various things where the sulfur molecule is important, as well as services where, obviously, the regeneration services, our hazardous waste services business, our Chem32 businesses all serve very high-value service businesses. Expanding further into those spaces would also be of interest.

Thank you.

Ladies and gentlemen, just a quick reminder: any further questions today, please press. And, gentlemen, it appears we have no further questions in queue at this time.
