Kurt?.

Thank you, Gene and good morning. First, I want to thank my Ecovyst colleagues for delivering a strong finish to 2023. Despite the economic uncertainty and operational challenges that we faced last year, our Ecovyst colleagues remain dedicated to their core purpose of delivering high-quality products and reliable services to our valued customers.

Despite the macroeconomic uncertainty, relative stability and demand fundamentals across the majority of our end users for both Eco Services and Advanced Materials and Catalysts helped Ecovyst deliver solid financial results for the fourth quarter of 2023.

High refinery utilization, favorable gasoline demand and the trend toward higher-octane and cleaner burning fuels continued to drive alkylate [ph] production in 2023, providing support for our regeneration services business where volume was up compared to the fourth quarter of 2023.

Sales volume for virgin sulfuric acid was also up compared to the fourth quarter of 2023, albeit, with weaker pricing dynamics associated with softer macroeconomic conditions, particular in advanced materials and catalyst. Fourth quarter sales were up considerably compared to the fourth quarter of 2022.

While polyethylene sales volume was lower compared to the prior year fourth quarter, higher pricing and strong demand for hydrocracking catalysts and customized catalyst applications contributed to the sales growth. Given these volume and pricing dynamics, our fourth quarter 2023 adjusted EBITDA was $70 million.

During the fourth quarter, we maintained our focus on the strategic initiatives and operational priorities that we believe are positioning Ecovyst to deliver strong growth in the future in our core and industrial applications as well as in the emerging allocations we discussed in our November Investor Day.

For the Zeolyst joint venture, these emerging applications include the ongoing expansion of sustainable fuel production, both for renewable diesel and sustainable aviation fuel and catalysts specifically designed for advanced recycling of plastic waste.

We are benefiting from the growth in renewable diesel today, and we expect our Zeolyst technologies for alcohol-to-jet SAF production to gain additional momentum this year.

For our advanced silicas portfolio, we highlighted a number of nascent platforms, including our AlphaCat advanced silicas and our AlphaSelect functionalized silicas for use in applications such as mobilized enzymes, carbon capture and clean water.

I'm pleased to announce that during the fourth quarter, we achieved our first sale of advanced silicas for enzyme applications, and we anticipate additional sales this year as we look to expand our support for all these emerging applications.

In light of our favorable financial results for the quarter, cash generation remained positive, providing a reduction in our net debt leverage ratio. We ended the year with a net debt leverage ratio of 3x, down from 3.2x at the end of the third quarter.

In terms of capital allocation priorities, continued reduction in our leverage ratio remains a key focus as we look to make substantial progress this year toward our target leverage ratio of below 2.5x. Lastly, over the past 3 years, we have made significant progress in supporting our customers with more sustainable products and technologies.

In addition, we have worked to drive more sustainable business practices across our organization. Consistent with the spirit of continuous improvement, 2 years ago, we were recognized by EcoVadis with a silver metal sustainability rating. Last year, in recognition of our continued progress, we achieved gold metal status with EcoVadis.

I'm now pleased to report that Ecovyst recently achieved platinum metal status with EcoVadis in recognition of our incremental efforts to integrate the principles of sustainability and corporate social responsibility into our overall business practices. This recognition places Ecovyst in top 1% of all companies rated in our peer group.

As we turn to Slide 6, I'll provide an update on our near-term demand outlook. We believe the long-term demand trends for the end uses we serve remain very compelling, and I want to emphasize that the longer-term end-use outlook growth expectations and financial targets we shared in our November Investor Day remain intact.

However, for 2024, we believe there is significant near-term economic uncertainty, arising from a number of factors, including persistent inflation, rising interest rates, destocking, geopolitical tensions and weak demand in Europe and China.

Given the current uncertain macroeconomic environment, we are cautious about the trajectory of near-term demand trends. As a result, while we anticipate stronger demand fundamentals in the second half of 2024, we have tempered our expectations for the first half of the year.

For our Regeneration Services business, we expect high refinery utilization with stable gasoline demand and increased exports in 2024. As alkylate demand continues to be driven by tightening fuel standards such as Tier 3, we expect these fundamentals will continue to provide a favorable backdrop for our regeneration services business this year.

For virgin sulfuric acid, in light of the significant impact that Winter Storm Elliott and the production headwinds we faced in 2023 had on sulfuric acid sales, we expect volume recovery for virgin sulfuric acid in 2024.

We specifically for our sales into the production of nylon intermediates, while destocking was a factor in the demand softness we experienced in 2023, we believe the destocking phase is behind us. However, the global demand outlook for engineered plastics remains uncertain, in part due to surplus capacity and continued demand weakness in Asia.

We expect sulfuric acid demand for the mining applications that we service to remain stable in 2024 with ongoing copper expansion projects in the U.S. and the longer-term projected global supply deficit for copper underpinning demand. We believe the economics of these expansion projects remain favorable with current copper prices.

For the wide range of industrial applications we serve, we expect the portfolio effect will provide a level of stability for virgin sulfuric acid sales in 2024, with stable to positive demand in many end-use applications serving to counter softer demand than others.

We expect relative stability in end uses such as lead acid batteries, water treatment and chlor-alkali to balance the potential for eroding demand in end uses such as paper and packaging where demand weakness is being driven by capacity rationalization in certain geographies.

Overall, for the first half of 2024, we see softer industrial demand for virgin sulfuric acid. And while significant amount of our virgin sulfuric acid sales are under long-term contract, we currently see weaker market sentiment resulting in pricing pressure for short-dated contracts and spot sales.

For our Chem32 catalyst activation business, we see demand remaining strong in 2024, supported by continued growth in sustainable fuel production and expanded customer interest. Likewise, we see stable demand for our treatment services business with demand and activity levels highly correlated to factors such as consumer spending.

Turning to Advanced Materials and Catalysts. For advanced silicas, we believe that the inventory destocking that adversely impacted demand for polyethylene catalyst over the second half of 2023 has run its course.

While market forecasts are projecting global polyethylene demand to be up 2% to 3% in 2024, we believe that excess global capacity will continue to weigh on operating rates. As such, we are not projecting a significant near-term change in the demand for polyethylene catalysts, but the prospect of a stronger second half of this year exists.

We believe we are well-positioned for a recovery in demand, particularly given our representation in North American and Middle Eastern markets, where raw material and energy costs provide more favorable production economics.

Following positive sales momentum in the fourth quarter in North America, we expect modestly lower operating rates in the mid-80% range with weaker first quarter sales as customers work through end-of-year inventories.

In the Middle East, we expect operating rates to remain robust, supported by a cost advantaged feedstock position and strong export activity. For Europe, we expect polyethylene demand to decline in 2024 due to the poor economic climate.

And in Asia Pacific, we expect the Lunar New Year and sluggish restocking activity to be a factor in the first quarter. Within our Zeolyst joint venture, our core applications include hydrocracking catalyst petroleum-based fuels and Zeolyst used in emission control applications.

Hydrocracking catalyst our high value add fixed bed catalyst that refineries change out every 3 to 4 years, even though we expect refinery margins to remain healthy for 2024, and many large customers completed catalyst change outs last year.

So we believe 2023 was likely a near-term peak year for sales of hydrocracking catalysts, and we currently expect that 2024 will be a lower cycle year for hydrocrack catalyst sales. In terms of sales cadence, we have lowered our sales projections for the first quarter due to revised order timing.

For our sales and emission control applications, we expect the current economic environment will translate into lower production and delivery of heavy-duty diesel vehicles.

Turning to the production of sustainable fuels, which include both renewable diesel and sustainable aviation fuel or SAF, our Zeolyst are used in the dewaxing phase of those sustainable fuels production processes. We expect robust sales in 2024, with sales slightly stronger in the second half of the year.

North American renewable diesel and sustainable aviation fuel capacity is projected to grow by approximately 33% this year, supported by attractive financial incentives with 8 production facilities expected to start up in 2024.

For the European Union, renewable diesel and SAF capacity is projected to grow by 43% this year with 9 facilities expected to start up in 2024. Looking forward, we see good progress in licensor activity supporting pilot production of SAF using alternate technology referred to as alcohol to Jet.

Our Zeolyst have a key role to play in the oligomerization [ph] phase of this emerging technology, where our catalysts are used to build the carbon chain in the production of SAF. We believe the focus on advanced recycling technologies for plastic waste provides significant growth opportunities for Ecovis.

We continue to work with industry leaders on the application of Zeolyst in these recycling processes in which our Opel Infinity family of Catalyst provides a step change reduction in thermal intensity for catalytic pyrolysis and where ZI catalyst can be used to enhance the quality of pyrolysis oil, providing higher value end products and expanding potential for use as feedstocks and chemical production.

As we discussed in our recent Investor Day, we have already had pilot sales of our catalysts for advanced recycling. This year, there are 12 advanced recycling plants for plastic waste recycling is expected to be commissioned. And with the momentum we see in this area, we continue to expect commercial sales in early 2025.

I'll now turn the call over to Mike for a more detailed discussion of our fourth quarter and full year financial results..

Thank you, Kurt. I will begin with a review of our fourth quarter and full year 2023 financial results. Fourth quarter sales, including our proportionate 50% share of sales from the Zeolyst joint venture were $226 million compared to $223 million in the fourth quarter of 2022.

The higher sales volume across both businesses and the benefit of continued favorable pricing within Advanced Materials and Catalyst was largely offset by the $9 million impact from the pass-through of lower sulfur costs as well as the pass-through of lower natural gas and freight costs within Eco Services.

Adjusted EBITDA for the fourth quarter was $70 million, up 1% over the prior year fourth quarter. Favorable pricing and higher sales volume were partially offset by lower net pricing in eco services on lower raw material pass-through pricing.

The consolidated adjusted EBITDA margin for the fourth quarter was 31%, in line with the fourth quarter of 2022. On a full year basis, total sales for 2023, including our proportionate 50% share of sales from the Zeolyst joint venture were $848 million compared to $953 million in 2022.

Of the change in sales, $86 million was associated with the pass-through effect on pricing of lower sulfur costs. The balance of the decrease reflects lower sales volume for virgin sulfuric acid, lower demand for polyethylene catalyst and the relative timing of niche custom catalyst sales.

This was partially offset by higher average selling prices across both segments. Full year 2023 adjusted EBITDA was $260 million, down 6% compared to $277 million for 2022, driven by the lower sales volume along with higher unplanned repair and maintenance costs. The full year 2023 adjusted EBITDA margin was 31%, up compared to 29% in 2022.

As we move to the next slide, I'll highlight the primary components of the change in adjusted EBITDA compared to the fourth quarter the prior year. Similar to the last several quarters, average sulfur costs for the fourth quarter of 2023 were lower than in the prior year.

The pass-through of these lower sulfur costs had an impact of $9 million in variable cost with a corresponding reduction in average selling prices. As such, the lower sulfur cost pass-through on sales during the quarter had no impact on adjusted EBITDA.

Our price to variable cost ratio continues to be favorable, while variable costs were lower for the quarter, the pass-through pricing on some of these costs, including natural gas and freight were also lower. However, implemented and base price increases continue to be favorable, generating a positive price-to-cost ratio.

Turning to the segment results, we will begin with Ecoservices. Ecoservices sales for the fourth quarter were $141 million compared to $160 million in the fourth quarter of 2022.

The change in sales primarily reflects the pass-through of lower sulfur costs of $9 million and lower pricing in regeneration services associated with the pass-through of lower natural gas and freight costs.

These factors were partially offset by higher regeneration services volume and higher demand for virgin sulfuric acid for mining and opportunistic spot sales. Ecoservices adjusted EBITDA was $48 million in the fourth quarter compared to $54 million in the prior year.

While demand remains strong in both regeneration services and version of sulfuric acid, the decrease in adjusted EBITDA was driven by lower net pricing associated with lower raw material pass-through pricing. Ecoservices adjusted EBITDA margin for the fourth quarter was 34%, in line with the fourth quarter of 2022.

Turning to Advanced Materials and Catalyst. Total fourth quarter sales for Advanced Materials and Catalyst, including our 50% proportionate share of Zeolyst joint venture sales were $84 million, up $21 million or nearly 34% compared to the fourth quarter of 2022.

For advanced Silicas, fourth quarter sales of $31 million were up 37% compared to the year ago quarter, reflecting higher sales across all product lines. While sales volume for polyethylene catalyst was lower compared to the fourth quarter of 2022, favorable pricing and the higher sales of niche custom catalysts drove the increase year-over-year.

For the Zeolyst joint venture, sales were $53 million, up $13 million or 32% compared to the fourth quarter of 2022, primarily driven by higher sales of hydrocracking catalyst. Fourth quarter 2023 adjusted EBITDA for Advanced Materials and Catalyst was $27 million, up $7 million or 34% compared to the year ago quarter.

with the increase driven by higher pricing and sales volume. Adjusted EBITDA margin for Advanced Materials and Catalyst was 32%, in line with the fourth quarter of 2022. Turning to cash and leverage on the next slide.

During the fourth quarter, cash generation was very strong, providing for a reduction in our net debt leverage ratio of 3x as we continue to make progress towards our net target of less than 2.5x. On a full year basis, free cash flow generation was $72 million.

This was in line with our recent expectations, but below the prior year driven by the lower adjusted EBITDA, lower dividends from Zeolyst joint venture, higher cash taxes and cash interest as well as an unfavorable change in working capital year-over-year.

As discussed in our Investor Day in November, we continue to target a cash conversion ratio of approximately 75%. For 2023, our cash conversion ratio was 75%. We continue to maintain a balanced approach for capital allocation with net leverage reduction remaining a key priority.

During 2023, we used cash to repurchase shares largely in connection with secondary offerings of our equity sponsors. In 2023, we repurchased 7.5 million shares for $79 million. Our balance sheet remains in strong shape.

At year-end, we had total available liquidity of $152 million comprised of $88 million of cash and availability under our ABL facility of $64 million. We have one tranche of debt outstanding, which matures in 2028. Excluding outstanding letters of credit, there were no outstanding borrowings under our ABL facility at year-end.

We have capped our interest exposure on approximately 75% of our outstanding debt out to the third quarter of 2026. And our weighted average cost of debt was approximately 5% during 2023. Now let's turn to guidance and expectations for 2024.

For 2024, we expect sales on a GAAP basis to be between $715 million and $755 million, and we expect our proportionate 50% share of sales for the Zeolyst joint venture to be between $145 million and $165 million.

As such, we anticipate total sales including our proportionate share of the Zeolyst joint venture sales to be between $860 million and $920 million or up approximately 5% at the midpoint compared to 2023.

In terms of the pass-through effect of sulfur pricing, we are currently expecting a very modest decrease in average sulfur pricing for the first half of 2024, with the impact on sales largely immaterial.

As Kurt discussed in his comments about our end-use demand outlook, the value of Octane and alkylate remains favorable, and we expect continued high refinery utilization to support regeneration services activity.

We expect a modest, but cautious recovery of virgin sulfuric acid sales relative to 2023, primarily related to demand for virgin sulfuric acid going into the production of nylon intermediates, and the expectation for higher year-over-year production volume. As such, we expect sales in Ecoservices to be up mid single digits.

In Advanced Materials and Catalyst, we expect improvement in demand conditions for polyethylene catalyst and growth in our customized catalyst applications to drive high single-digit to low double-digit sales growth in advanced silicon. And for the Zeolyst joint venture.

While we expect continued growth and sustainable fuel catalyst sales in 2024, sales of hydrocracking catalysts are expected to be significantly lower which is typical when coming off a peak year like we experienced in 2023. For 2024, we are expecting adjusted EBITDA to land in the range of $255 million to $275 million.

In terms of segment expectations, for the full year 2024, we expect adjusted EBITDA for Ecoservices to reflect a mid to high single-digit percentage increase compared to 2023 based on the anticipated recovery of virgin acid sales into nylon intermediates, strong virgin acid sales into mining and higher contracted pricing and regeneration services.

This is somewhat offset by downward pressure on virgin acid pricing driven by the uncertain macroeconomic environment and $10 million to $15 million of higher maintenance and turnaround costs associated with enhancing our operational reliability, to help ensure long-term volume increases as we discussed during our November 2023 Investor Day.

For Advanced Materials and Catalyst, we expect 2024 overall adjusted EBITDA to be in line with 2023. Advanced Silica is expected to be up on a high single-digit basis driven by more normalized demand growth for polyethylene catalyst and sales into emerging areas.

Adjusted EBITDA for the Zeolyst joint venture, however, is expected to be down on a high single-digit percentage basis, driven by lower sales of hydrocracking catalysts off a peak year in 2023 and anticipated unfavorable fixed cost absorption associated with production and sales timing and increased cost to accelerate the growth in our emerging applications.

In addition, we expect our corporate costs to be around $30 million on an annual basis. For the full year 2024, we are expecting adjusted free cash flow of $85 million to $105 million including CapEx of $70 million to $80 million in 2024.

The higher CapEx reflects costs associated with the previously announced expansion of advanced silicas capacity and our Kansas City site and investment in our Chem32 catalyst activation business.

Given this expectation for cash generation and assuming no uses of cash for other capital allocation priorities, we expect to delever nearly half a turn, resulting in significant progress towards our target net debt leverage ratio of below 2.5x.

For interest expense, taking into account the interest caps that we have in place which cover approximately 75% of our exposure, we are projecting a range of $45 million to $55 million, with a weighted average cost of debt of approximately 5.5%.

Having covered our expectations for the full year of 2024, I want to provide some directional guidance for the first quarter of 2024. On a consolidated basis, we expect first quarter 2024 adjusted EBITDA to be approximately $40 million.

For Ecoservices, in light of the impact of winter storm Elliott and impact of the extended turnarounds in the first quarter of last year, we expect first quarter 2024 adjusted EBITDA to be up approximately 10% compared to the first quarter of 2023.

For Advanced Materials and Catalyst, we expect first quarter 2024 adjusted EBITDA to be between $7 million to $8 million.

The lower adjusted EBITDA compared to the prior year is primarily driven by a cautious view around the recovery of the polyethylene market and anticipated unfavorable fixed cost absorption associated with production and sales timing. I will now hand the call back to Kurt for some closing remarks..

Thank you, Mike. Despite near-term economic uncertainty, we remain positive on the long-term growth opportunities for Ecovyst. We believe our core and industrial businesses will continue to experience solid growth.

We have well-established customer relationships, leadership positions in the end uses we serve and we have articulated our plans to drive efficiency gains and to support sales growth through automation, debottlenecking opportunities, capacity expansions and through reliability initiatives in our Ecoservices segment that will also translate into incremental volume and sales opportunity.

For our Regeneration Services business, we believe the role of alkylate in the production of cleaner burning fuels is well appreciated. And the long-term demand outlook for refined product North America and the export markets our customers serve, will continue to provide opportunities for growth.

Although we see some near-term demand softness in some industrial applications for virgin sulfuric acid, mining demand remains strong, and we expect further improvement in demand for virgin sulfuric acid sales in the production of nylon intermediates as the global economy improves.

We also believe the portfolio effect for the balance of our industrial applications will continue to provide a level of overall stability. In terms of our sales of polyethylene catalysts, we believe global polyethylene demand will return to historic growth rates of approximately 3%.

Specifically, for Ecovyst, we expect our sales of polyethylene catalyst will continue to grow differentially to the overall market, benefiting from our customized catalyst design approach and our leading supply share positions in North America and the Middle East, which benefit from advantaged feedstock and energy costs.

Lastly, we have announced a significant expansion of polyethylene catalyst production capacity at our Kansas City site that is supported by firm customer commitments, providing further support for our future growth expectations.

Moreover, we are energized by the opportunities for growth provided by emerging technologies, which are not just aspirational. We continue to see robust growth in catalyst supporting the production of sustainable tools.

We have the technology leadership position for Zeolyst for advanced recycling technologies, and we have developed advanced silicones and functionalized silicas that position us to capture growth in enzyme minimalization in food, chemical and biomass-based processes as well as carbon capture and water treatment applications.

In summary, we have a portfolio of products and technologies that we believe provide for compelling organic EBITDA growth, as we discussed in our Investor Day. The long-term growth trends supporting Ecovyst products and services is reflected in the anticipated 2024 volume growth across the majority of our product lines.

Our current guidance reflects our caution around near-term demand conditions and the expected off-cycle year for event-driven hydrocrack sales.

As I indicated earlier, we believe the second half of the year could provide for improved demand conditions, including stronger sales of virgin sulfuric acid and polyethylene catalysts, and we will capture opportunity for incremental growth as they arise. At this time, I will ask the operator to open the line for questions..

Thank you, Mr. Bitting [Operator Instructions] And we will go first to Patrick Cunningham at Citi..

Hi. Good morning. This is Eric Zhang on for Patrick.

My first question is, what is driving the higher pricing through key catalysts? And do you expect that trend to continue?.

Hi, Eric. This is Kurt.

Well, for polyethylene, we do believe that destocking that we saw really in the latter half of 2023 is largely behind us, and we do expect double-digit sales growth during the year, albeit weighted towards the second half of the year, and we've implemented price increases as time goes along and has allowed us on our contracted prices.

Just a further comment really on polyethylene, our expectations there it's geographic-centric as well where most of our sales are centered in North America as well as the Middle East, where those regions have a high advantage in terms of raw materials and lower energy costs.

Europe, we're less exposed and less exposed in Asia Pacific in those two regions generally have more of a muted recovery or less of an uptick this year..

Got it. Thank you. And my last question is within Eco Services, can you elaborate on any trends that you're seeing with existing customers recontracting -- have there been any difficulties in getting customers to reassign? Thank you..

Yes, thanks for the question. So when you look at the regeneration business every year, those contracts are generally longer in length, so anywhere 5 to 10 years. So any given year, there's a certain basket of contracts that are up for renegotiation and recontracting.

So I would say as time has gone along, we've re-upped those customers, and we've been successful at implementing price increases as time has gone along. In Virgin asset about 90% of our customers are under a long-term contract basis. The 10% that we call kind of spot sales or short dated contracts.

That's where we've seen a little bit of pricing pressure, as I've mentioned on the call. And that's really related, I would say, mainly to the industrial space where we see some caution from some of those industrial consumers around 2024..

Great. Thank you..

Thank you. We go next now to Aleksey Yefremov at KeyBanc Capital Markets. .

Thanks and good morning, everyone.

Just a follow-up on the industrial piece of Virgin asset sales, could you quantify the magnitude of this price pressure, either as a total percent of your virgin asset business or as a percent of that bucket of short-term contracts?.

Sure. So Virgin as again, when you look at our portfolio on Virgin acid, 90% of it is really under long-term agreements, which we are adjusting on longer term contracts, right? So it's just that that's on that short dated or we call spot -- spot sales, those sorts of things.

So what we see in this area is, again, some cautious customers on the industrial side. And there's also been some rationalization really in the pulp and paper industry. we don't move a lot of volume into that industry, but it has created, I guess, some pockets of oversupply in different geographies where we don't operate.

But that's created some, I'd say, temporary imbalances in a couple of the geographies that really had to settle itself out.

So if I had -- if we had to quantify that really, Aleksey, you talk about 10% of our virgin acid portfolio is probably $5 million to $10 million in terms of pricing that's subject to this pressure that we're seeing in the industrial space..

Thanks, Kurt. Very helpful.

You mentioned accelerated increased costs driven by investments in these emerging applications kind of hard from outside to judge us is because it just cost more to do what you envisioned? Or is it really that there's bigger opportunity and those opportunities are coming faster, if you could elaborate on this?.

Yes. So if you -- as we stated during our Investor Day, growing our emerging technologies is really a key priority for us. When we look at some of the things like advanced plastics recycling, sustainable fuels, the advancements now that we're making on the mobilized enzymes.

So we are really on the front end of that, where we're building out our capabilities in those areas, building out our sales and marketing capabilities in these areas. So we're making those front-end investments as expected to deliver long-term sales as we outlined in our Investor Day..

Thanks a lot..

Thank you. We go next now to John McNulty at BMO..

Yes, good morning. Thanks for taking my questions. So question on EBITDA and advanced materials and catalysts. So it looks like the first half is going to -- there were -- the first quarter is going to be almost half of what it was the prior year, which kind of implies the back half or the remaining three quarters, basically flattish.

So I guess, can you help us to think about where the improvement comes from is the bulk of it, just the lumpiness in HPC catalyst side or is it the polyethylene ramp that you’re talking about. I guess what’s the bigger contributor to kind of the weakness in 1Q and the snap [indiscernible] as we look under the under the remaining three quarters..

John, this is Mike. Thanks for the question. Yes, it's a combination of all those factors, right? So we mentioned earlier that we are seeing a little bit of a cautious feel in Q1 around polyethylene starting out, but we do expect polyethylene demand to continue and actually improve over the prior year, call it, in a double-digit basis.

We also see that hydrocracking, while we came off a peak year from last year, it is a little lighter in Q1 than originally anticipated, but we do see it growing in Q2, Q3 and then into Q4. So it's a little bit of the nature of the business, primarily around the hydrocracking and the timing along with some of the niche custom catalysts.

Polyethylene is more constant. However, just given off of what we saw in 2023, it's a little lighter starting out, but it's ramping up certainly in the later half of the year..

Got it. Okay. No, that makes sense.

And then in one of the slides, you highlighted some weakness in the heavy duty truck market with which I assume is tied to some of the -- the new regulations where there was maybe a little bit of pull forward, I guess, how long does that normally last? Is that a year? Does it tend to last a little bit longer than that? I guess how should we be thinking about that?.

Yes, thanks, John. There's a couple of headwinds there really in the trucking where there's just a general, I'd say, slowdown in that transportation segment right now, which is, I think, linked to the general economic uncertainty going on.

So -- and then they're also coming off -- working off a pretty big backlog that had developed in '21, '22 and '23, where a lot of trucks were -- there was big back orders and they've worked those off. So you see some slowness there.

Additionally, the Euro VII regulation that was due to go in effect in 2027, Europeans have delayed that for 2 years, which has pushed off some of the I'd say, next-generation catalyst technologies that we're going to go into those trucks that we're going to reduce emissions by 80%.

So the combination of those things has kind of created a little bit of a headwind for that segment this year..

Got it. Thanks very much for the color..

Thank you. We go next now to David Begleiter at Deutsche Bank..

Thank you. Good morning. Kurt, in Ecoservices, you had a number of headwinds in 2023, the winter storm, outages, turnarounds and some weak demand and destocking.

So given that, why isn't the EBITDA growth a little faster than mid 5% plus in '24?.

Yes, sure. Thanks for the question, David. So as we stated on the call and a few times, it's we've taken a cautious look for 2024.

Many of our customers, particularly in that -- I'd say that industrial segment have adopted cautious approaches for 2024, and that's played into our overall opinion on the demand trends as -- especially as it relates to virgin sulfuric acid.

But when you look at the -- what we expect from 2024 in Ecoservices refining margins, the refining business remains healthy. We expect a strong year for regeneration. The treatment services business and Chem32 both look to have very full schedules this year.

It's the virgin acid business where we do plan on moving more volume into the market this year particularly into nylon, where there was headwinds last year, we see a recovery there. I wouldn't say it's necessarily an up cycle year.

However, we do expect to move more product into that nylon segment, where we see that some of the headwinds on Ecoservices is that earlier on one of the questions I talked about that industrial space and the pricing pressure is creating in that short-term and spot pricing segment of the virgin acid space as well as we're spending about $10 million to $15 million more on maintenance and reliability this year.

During the Investor Day, we talked about we have a long-term reliability enhancement program that we're instituting, which is a combination of really additional resources at the plants as well as some automation, which is there really to deliver higher reliability as well as debottlenecking at the plants over time.

So that's -- some of the change you see there is really pushing in that extra cost to kick off that reliability enhancement program..

And Kurt, on that program, is that a one-time effort or should we -- i.e., in '25 should that come back down by $10 million to $15 million? Or should that be sustained at this higher level?.

Yes. Some of that will be, and I didn't mention too, we do have additional turnaround costs. So that will -- some of that will be sustained because it's going to be -- the resources we're putting in place will be on a sustained basis.

We do have accelerated turnaround costs this year, which it's -- those mostly are actually going to take place in the first half of the year. And then the automation piece that we're putting in place, obviously, will go on to the plan. So I would think a portion of that will be sustained over the horizon..

Thank you..

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

Hi, good morning. So first question I had was given what has happened in '23 to your business, how have you adjust in '24? I mean are you through all the inventory that you might have had in '23 because of disruptions and so forth.

So what kind of lingering effects are there in '24 from those effects in '23?.

Yes, good morning, Hamed. I think really what -- in terms of 2023, we obviously had $20 million-ish of headwinds that were operational related in the Ecoservices business when you go back to the winter storm that started out at the beginning of 2023, and then we had the extended maintenance downtime at the Houston plant.

So we don't expect those events this year. Obviously, I just talked about the enhanced reliability program, which we will yield higher volumes. And we do expect to produce and sell more virgin sulfuric acid volumes this year, even though I've talked about some of the industrial headwinds in some of the pockets in the virgin asset market.

I think the other areas that we talked about last year that were headwinds for us was polyethylene catalysts, which in the second half of the year, there was destocking that went on. We see that abating and recovering, and as Mike said, particularly in the second half. So we do expect polyethylene catalysts to be up in double digits this year.

And then secondly, the Nylon segment, which impacted the virgin acid business last year in the second half, we saw destocking in that area. We do expect nylon volume to be up for us this year, albeit not certainly a high cycle year, but certainly a recovery there..

Okay. And my last question is on the slides provide today, you're highlighting the slow conditions for heavy-duty vehicles. That's a new item for you on the slide.

Why is that such a big deal now versus prior quarters where that was not even an issue or even from a positive side or negative side? I mean, how bad of a drag is this that you're highlighting in now?.

Yes, I think, Hamed, it's not -- I think in the past, over the past year or two, the business was largely just moving along in terms of the backlog of the heavy-duty diesel vehicles. It's not an overly huge segment for us.

And essentially, we view that market as we see headwinds there in terms of just the demand for our overall heavy-duty diesel vehicles as well as the regulation thing that I mentioned earlier on Euro 7. But when we look at it from a sales standpoint, it's flattish for us. So I wouldn't call it necessarily a huge drag for us.

It's just it's an area that we see in the segment that there definitely are headwinds in that segment..

Okay. Thank you..

[Operator Instructions] We'll go next now to David Silver at CL King..

Yes, hi. Thank you very much. I had a question maybe about some of your spending initiatives over the next year. But for starters, there is something of an increase on -- in your CapEx spend. And I'm guessing some part of that is Kansas City, and along those lines, just with the time line there.

I was just -- I was wondering -- or I was wondering if the spend might -- the CapEx spend might have even been a little bigger to prepare for the anticipated demand growth. And then beyond that, I'm just wondering if you could articulate or highlight any increase in either R&D spend or pre-commercialization type of spending.

But beyond the beyond, I guess, the operational things. I mean what other kind of spending initiatives should we be thinking about to support your growth, which you highlighted in the release and in some of your comments here. But is there a way to kind of get a bigger -- a clearer view of that, please..

Yes, hi, David. Good morning. This is Mike. So on the first part of the question around capital spending, you are correct. We do see about -- given our guidance range at the midpoint roughly $10 million increase in CapEx spending. The predominance of that is associated with the Kansas City expansion.

And I think we mentioned this during our Investor Day that would take a period of time over -- certainly over at least 2-year period going into 2025. So our spend on that facility is not a bottoms-up approach. We already have structures and availability there. We're just expanding upon that.

So the CapEx cost is not perhaps as significant as you might think, with building a brand new plant, but we are adding about 50% capacity for making their polyethylene catalyst there. We also have some additional costs in the capital spending around Ecoservices to continue to start to look and expand our Chem32 Catalyst activation business.

So there's some spending in there as well. When you look at the R&D and free commercial, Kurt mentioned earlier that we are seeing some additional spending in the -- just as we start to ramp up some of our emerging products. So we are seeing a little bit of additional cost there.

But again, as we mentioned, we're very excited on where our sales have been taking us. We've already had some sales in 2023 related to the biocatalysis and a lot of it is exactly how we articulated during our November Investor Day.

And hopefully, we also talked a little bit more about the spending on Ecoservices related to the reliability and turnaround costs that we talked about earlier. So hopefully, that covers some of your cost -- your questions on the cost and spending..

Yes. Thank you for that. And then maybe just from another angle. Yes, I was wondering about the operational plans, the downtime overall planned by your portfolio of refining customers. So I guess refining margins largely have been very healthy for the last few years.

And anecdotally, I guess, a lot of refineries have deferred or delayed downtime as much as they could to take advantage of what they viewed as favorable profit opportunities. As you kind of look at the planned downtime and planned operating strategies that you're refiner customers have shared with you.

I mean should we expect another year of very high or close to full utilization there? Or are there some major outages or downtime planned relative to maybe 2023 or 2022, excluding the weather events? Thanks..

Sure. Thanks, David. So in terms of when we look at [indiscernible] refinery downtime, it affects two parts of the business differently. When you look at Ecoservices, on the acid regeneration we don't really see a particularly high amount of customer turnarounds this year in their calculation units.

So we're expecting, I would say, more of an average year you look at hydrocracking catalysts, obviously, coming off a peak cycle year in 2023, selling hydrocracking catalysts, which some of those turnarounds took place in Q4 of 2023. Some of them are taking place in Q1 2024, they were buying the catalyst to have it on site for their turnaround.

So we expect, and again, hydrocracking to be more of a low cycle this year, so we do expect less turnarounds in that space as well. But those are for our customers. So there certainly are other refiners or other regions that could have different issues.

But in general, I think we see certainly average in the eco-service side and less turnarounds in hydrocracking just because it's an off-cycle year..

Yes. Yes, you did highlight that there. Okay. That’s great. Thank you very much..

And we'll take a follow-up question now from John McNulty at BMO..

Yes, thanks for taking my follow-up. So on the polyethylene catalyst demand, which is a pretty strong forecast for the year, up double digits, I guess can you help us to think about how much of that's just core industry growth versus account wins because I think you have had a bunch of wins and some assets are still in the process of ramping up.

So that may be some of the benefit.

But can you help us to think about that high level?.

Sure. I mean I think it's a mix, really, John, of both wins and just increased utilization rates. So you see a recovery, particularly I would Middle East and North America right now at very low natural gas prices are enjoying a huge arbitrage window in polyethylene production. So we obviously have a little heavier weighting to those areas.

So we're seeing some recovery in that area. And again, I think Mike mentioned we are -- it's more a more second half weighted. So a lot of it's recovery, but yes, some -- and in some of its recovery of new account wins that we've had as well. So it's a little bit of a mixed bag.

But if I had to give it the weighting us, I'd say it's more just on the general recovery side..

Got it. Thanks for the color.

And ladies and gentlemen, it appears we have no further questions today. So that will bring us to the conclusion of Ecovyst's fourth quarter 2023 Earnings Conference Call. We'd like to thank you all so much for joining us today and wish you all a great remainder of your day. Goodbye..
