Good day, and welcome to the AdvanSix Third Quarter 2022 Earnings Conference Call. (Operator Instructions) Please note, this event is being recorded.
I would now like to turn the conference over to Adam Kressel, Vice President of Investor Relations and Treasurer. Please go ahead.
Adam Kressel - Director of IR
Thank you, Betsy. Good morning, and welcome to AdvanSix's third quarter 2022 earnings conference call. With me here today are President and CEO, Erin Kane; and Senior Vice President and CFO, Michael Preston. This call and webcast, including any non-GAAP reconciliations, are available on our website at investors.advansix.com.
Note that elements of this presentation contain forward-looking statements that are based on our best view of the world and of our business as we see it today. Those elements can change, and the actual results could differ materially from those projected, and we ask that you consider them in that light. We refer you to the forward-looking statements included in our press release and earnings presentation. In addition, we identify the principal risks and uncertainties that affect our performance in our SEC filings, including our annual report on Form 10-K as further updated in subsequent filings with the SEC.
This morning, we'll review our financial results for the third quarter of 2022 and share our outlook for our key product lines and end markets. Finally, we'll leave time for your questions at the end.
So with that, I'll turn the call over to AdvanSix's President and CEO, Erin Kane.
Erin N. Kane - CEO, President & Director
Thanks, Adam, and good morning, everyone. Thank you for joining us and for your continued interest in AdvanSix. As you saw in our press release, AdvanSix delivered third quarter results consistent with our update in October that reflect the resilience of our business model and our ability to navigate challenging conditions.
Let me share a few highlights on Slide 3 before Mike covers the details of our financials in a moment. Despite the unfavorable impact of the previously announced extended plant turnaround, our sales grew year-over-year, as our commercial execution captured higher pricing, particularly across our ammonium sulfate and nylon product lines to offset continued higher inflation and lower production output.
Our healthy cash flow performance continued to support smart and disciplined deployment of capital in the quarter, including reinvestment in the business, approximately $17 million of cash returned to shareholders in the form of dividends and share repurchases, as well as further debt reduction. With the turnarounds complete, our facilities are now focused on operating at our typical high utilization rates, which we expect to continue into 2023.
Looking forward, we expect strong underlying agricultural fundamentals to support robust nitrogen and sulfur fertilizer industry demand into the heart of the 2023 domestic planting season. Nearly 1/3 of our portfolio is in the agricultural sector, including ag chemicals and our position in this attractive market has extended even further through our acquisitions of U.S. Amines as well as CIS. We know this space well, and we continue to invest for growth. As we have shared previously, we are today producing more high-quality granular grade ammonium sulfate to meet the growing demands of our customers. Overall, this is a core and critical product line for our business.
Like every company, we are also closely monitoring the heightened macro uncertainty and concerns of an economic slowdown or recession and any potential impacts on the industries we serve. We would now characterize the North American demand for nylon and chemical intermediates as mixed overall. While some end markets like commercial construction and solvents are holding up, we are seeing softness in consumer durables and residential applications.
We've consistently demonstrated our ability to navigate, perform and execute in a multitude of environments. Our low-cost position, diverse portfolio, significant exposure to the North American region in terms of sales and operations, and our ability to stay highly disciplined around cost provides us with a solid foundation and proven track record to perform through all conditions.
In this environment, we continue to be highly focused on executing what is in our control, including driving superior operational and commercial performance to meet the evolving needs of our customers, building capabilities to strengthen our innovation and portfolio resiliency and enhancing our capital deployment.
For the fourth quarter of 2022, we expect performance to rebound towards results demonstrated in the first and second quarters of this year and remain confident in our ability to build sustainable long-term shareholder value.
With that, I'll turn it over to Mike to discuss the financial details of the quarter.
Michael Preston - CFO & Senior VP
Okay. Great. Thanks, everyone, and good morning, everyone. And now on Slide 4, where I'll provide a summary of the third quarter 2022 financial results. Sales of $479 million in the quarter increased approximately 7% versus the prior year. Market-based pricing was favorable by 18% compared to the prior year, driven by higher pricing across our ammonium sulfate and nylon product lines. To a lesser extent, raw material pass-through pricing contributed to 4% of top line growth following a net cost increase in benzene and propylene. The acquisition of U.S. Amines added approximately 3% to sales as well.
Sales volume decreased approximately 18%, driven primarily by the unfavorable impact of the extended planned turnaround and lower production output compared to the prior year. Adjusted EBITDA was $33 million, and I'll walk through the key year-over-year variances on the next slide.
Adjusted earnings per share was $0.43. Our effective tax rate was 21.4% in the third quarter versus 23.8% in the prior year period. And finally, free cash flow reached $37 million. Cash flow from operations of $59 million in the quarter decreased $18 million versus the prior year, primarily due to lower net income, partially offset by the favorable impact of changes in working capital. Capital expenditures of $22 million in the quarter increased $9 million versus the prior year.
Now let's turn to Slide 5. Here, we highlight a few of the key drivers of our third quarter adjusted EBITDA performance year-over-year. Pricing of raw materials was a $49 million benefit. Tracking our key variable margin drivers, performance in caprolactam and nylon over benzene was up year-over-year, reflecting balanced North America industry supply and demand, where we primarily participate.
Ammonium sulfate on a net price over natural gas and sulfur basis also continued its positive trend year-over-year, reflecting the strong underlying ag environment, as well as our ability to drive our sulfur nutrient value proposition.
In the quarter, we saw a roughly $16 million unfavorable impact from increased plant spend, primarily driven by higher natural gas utility prices and an increase in non-raw material inflation primarily on transportation costs. Volume and other items were approximately $34 million unfavorable in the quarter, primarily due to lower production output versus the prior year. As a reminder, in the third quarter last year, we had roughly $2 million of proceeds related to the PES insurance claim.
Lastly, the impact of our plant turnarounds was a known headwind to our year-over-year performance, as we did not have any turnaround activities in the prior year quarter. The overall impact of third quarter 2022 was approximately $44 million. This was $15 million higher than expected, primarily due to additional required maintenance at our Frankford phenol plant, which contributed to reduced production across our integrated value chain and a delayed ramp to full operating rates at our Hopewell and Chesterfield sites.
Now let's turn to the next slide. On the left side of Page 6, we've once again highlighted our third quarter free cash flow generation, which was driven by a $39 million favorable impact of changes in net working capital. Accounts receivable represented approximately $59 million of that total, as a result of lower sales in the third quarter compared to the second quarter. This was partially offset by an approximately $19 million use of cash from accounts payable as anticipated due to higher raw material costs in the prior quarter and timing of payments. I would highlight that over the last 12 months, our free cash flow yield is roughly 13%, and our free cash flow conversion is 97%, which reflects the healthy cash flow generation and quality of earnings of our business model delivers.
On the right side of the page, we've once again depicted our capital deployment since 2020. We have ramped up our deployment in 2022, including an increase in organic capital investments, the acquisition of U.S. Amines, which is tracking to plan and a meaningful step up in cash returned to shareholders through share repurchases and dividend payments. Year-to-date, we've returned a combined $35 million to shareholders. Our quarterly dividend of $0.145 per share will be made payable on November 29th, and we repurchased an additional $5 million of shares in October.
Our balance sheet remains quite strong, a benefit heading into an uncertain macro environment and providing flexibility with respect to capital allocation. We continue to execute a disciplined and balanced capital allocation strategy that we believe is a value enhancer to our core strategies and a key focus to support attractive total shareholder returns.
So with that, let me turn the call back to Erin.
Erin N. Kane - CEO, President & Director
Thanks, Mike. I'm now on Slide 7 to discuss each of our key product lines. Starting with nylon. We've seen the global composite price raw spreads modestly improved in the third quarter year-over-year, led by North America. China and Asia have continued to see volatility from a feedstock perspective, as well as weakened demand overall. In Europe, while we have seen some producers return to production from temporary shutdowns amid historically high input costs, third-party industry sources are citing utilization in the region remaining around 50% and resulting in a shift towards more imports into the region.
The North American supply and demand dynamics, while rebalanced, have continued to support pricing and spreads, which have outperformed the global benchmarks. We have seen softness in consumer durables and residential end markets with commercial construction and packaging more resilient. We know this portfolio is more sensitive to consumer demand, particularly for our engineered plastics resins, so we're keeping a close eye on any further changes in customer buying patterns.
Moving to ammonium sulfate, elevated energy input costs, alongside resilient underlying ag fundamentals drove higher nutrient values in the third quarter on a year-over-year basis. On a sequential basis, we did experience quarterly sales seasonality, reflecting both geographical and product sales mix considerations. Given the pricing environment and demand dynamics coming off the weather impacted and compressed second quarter planting, the seasonality impact this year was above the higher end of the historical range typically seen.
While we have observed some cautious buying behavior given the macro environment, overall underlying agricultural industry fundamentals remain favorable heading into 2023. This is supported by crop prices, stock-to-use ratios, constrained nitrogen fertilizer supply, as well as continued duties on ammonium sulfate imports from China. While raw material input costs have seen reductions recently, costs remain relatively high in other regions, namely Europe, steepening the industry cost curve and supporting tight overall nitrogen fertilizer supply. But all together, the fundamental support continued robust fertilizer demand and pricing going forward into 2023.
And lastly, turning to chemical Intermediates, industry realized acetone prices over refinery grade propylene costs improved sequentially in the third quarter. Propylene costs have trended lower on ample supply over the last few months. This has come at a time when acetone imports into the U.S. have remained stable and phenol operating rates globally have come down on softer demand, particularly into building and construction and other industrial applications. Pricing and spreads overall remain at healthy levels relative to prior periods, and we'll continue to monitor any changes in downstream demand.
Let's turn to Slide 8. Our outlook for the remainder of 2022 remains largely consistent to what we have shared previously. Again, while we would now characterize North America demand for our nylon and chemical intermediates product lines to be mixed overall, we continue to expect those favorable underlying agricultural industry fundamentals to continue. Operationally, we continue to focus on safe, stable and sustainable performance, while driving less variability in utilization rates, which in turn, drives improved customer experience and higher returns for the business.
For the full year 2022, CapEx is tracking to approximately $95 million. With the planned turnarounds complete, we do not anticipate any fourth quarter turnaround costs and are targeting our facilities to operate at our typical high utilization rates moving forward.
We expect the pretax income impact of planned plant turnarounds to be in the range of $28 million to $33 million in 2023 compared to approximately $50 million for the full year 2022. Next year, we expect the [larger] of our planned plant turnarounds to again occur in the third quarter.
And lastly, we expect our effective tax rate for this year and next year to be approximately 24% and anticipate cash pension contributions to be approximately $20 million in 2022, including a $5 million contribution in the fourth quarter, which we expect will bring our defined benefit plan to a nearly fully funded status.
Let's turn to Slide 9 to wrap up before moving to Q&A. Consistent to what we have shared last quarter, we continue to believe that AdvanSix offers a compelling investment thesis, as there are a number of factors supporting robust performance and attractive returns for the business and our shareholders over the short, medium and long term. Our leading North American position and advantaged asset base, coupled with our efficient and lean business model, provide inherent competitive advantages.
As industry cost curve steepen globally, we are in a strong competitive position with significant exposure to the advantaged North American region relative to Europe and Asia. Roughly 90% of our sales are in North America, while 100% of our manufacturing and primarily all of our raw material purchases are located in the region as well. And as a reminder, approximately 50% of our business is on formula or index-based contracts, where changes in raw materials are contractually passed through to customers with minimal lag.
Our leading product portfolio is aligned to a diverse set of end market applications. We are more than just a nylon company. In fact, our chemical intermediates and ammonium sulfate product lines are a significant portion of both our sales and volume. Not only are these products contributing to top line results, but they are very important drivers of profitability for the company. And that is precisely why we have dedicated sales, marketing and technical resources focused on serving customers and developing product line strategies to both drive performance and capture growth opportunities. The diversity of our end market exposure also helps insulate the company from significant variability in any one product line, as demonstrated by our results in several environments.
Supplementing our exposure to diverse end use applications, we have enhanced our sales mix through our differentiated product portfolio, which represents over $200 million in annual revenue with margins that are twice our average base business gross margins. And we continue to make smart and disciplined investments in our assets to sustain and improve throughput and profitability.
Importantly, we have substantially increased the earnings power of this business with our focus on through-cycle profitability. Since 2017, we have structurally added a net $50 million plus of annual incremental EBITDA benefit to the base business through significant contributions from those differentiated products, our high-return growth and cost savings capital projects, improved operational performance with respect to ammonium sulfate granular conversion and the current performance of our 2 recent acquisitions.
Lastly, our enhanced capital allocation framework provides upside and optionality for further value creation. We have a healthy balance sheet, and we'll continue to maintain prudent leverage levels in the current environment. We are targeting accretive M&A for bolt-on opportunities, providing growth and synergies. And reflecting our confidence, we've also stepped up our return of cash to shareholders with the recent dividend increase alongside our opportunistic share repurchases. We feel very good about the strategies we've implemented, which continue to support expectations for AdvanSix's long-term sustainable performance.
With that, Adam, let's move to Q&A.
Adam Kressel - Director of IR
Great. Thanks, Erin. Betsy, can you please open the line for questions?
Operator
(Operator Instructions) The first question today comes from Vincent Anderson with Stifel.
Vincent Alwardt Anderson - Associate
Thanks. Good morning, everyone. So just with regard to the 4Q outlook, I think the top line drivers are fairly well understood. But when I'm looking at sulfur gas and propylene prices and what they've done recently, what kind of keeps the first half earnings, the target for 4Q and not the floor for 4Q?
Erin N. Kane - CEO, President & Director
Yes. No, there's a number of things and great question as always here, Vincent. We're -- obviously, you've got sort of sequentially the considerations coming out of the outage, and then you have the dynamics really across all 3 businesses. So in ammonium sulfate, obviously, we're moving into the season. So we are coming off of the fill in Q3 moving towards the first half of next year, which will be the height of the season, as you know, as we get into Q2.
Right now, as we see the markets in ammonium sulfate, there's a lot of emotion that we have to continue to watch. I think it's -- the underlying long-term fundamentals are sound, but there is some cautious buying behavior, as we continue to -- as we see every year, right? When you think about the timing of how purchases and sales come in, you have folks that continue to watch and time their purchases, as we go. But again, we anticipate that this will be our typical seasonal move forward in the fourth quarter. But obviously, we have to wait until we get into the first half of next year to see sort of the peak performance in that particular product line.
And as we noted in nylon and chemical intermediates, here again, we have the mix from a consideration. While spreads continue to hold up, as we see certainly the residential applications coming off with mortgage rates, those areas are continuing to see softness. We see that both in nylon as well as in do-it-yourself applications through our acetone chain and other intermediates.
And then you have the resiliency in packaging, as well as areas into acetone distribution for direct solving use. So there is quite a bit going on in that space. And as you know, our utilization rates, this is how we target the operating model of the business. So volume can be consistent perhaps on a year-over-year basis, but that pricing dynamic will play out, as we see how demand continues into -- throughout the quarter.
Michael Preston - CFO & Senior VP
Yes. Vincent, the only thing I would add is when you're thinking about rebounding back to the first half performance, the AS, I would say, value is the greatest in the first half of the year, particularly in the second quarter, where you're in the peak of the season, and we sell the most of the domestic granular products. So that is definitely a consideration here in the fourth quarter when you compare to the results in the first half of the year, right? You need to factor that in as well.
Vincent Alwardt Anderson - Associate
Yes. And then actually, the dividend, there was a nice increase. I'm just curious if we should read anything into that in terms of maybe you're seeing something even more incrementally positive over the course of this year that may be the confidence to underwrite that increase? Or did you originally declare the dividend at a level that you knew you would be able to grow for some time before you had to reevaluate [them]?
Michael Preston - CFO & Senior VP
Yes. Well, it was about a year -- over a year ago that we had announced and initiated a dividend. We felt given the free cash flow conversion and the outlook, it was an appropriate time after about a year to reevaluate the dividend policy and hence, which resulted in a 16% increase, which we feel very comfortable with and provides a very competitive yield to our shareholders.
As we go forward here, we'll continue to evaluate the dividend policy. We're very comfortable with the 16% increase, and we'll continue to evaluate based on our outlook and our free cash flow generation. So we've definitely stepped up the return of cash to shareholders in terms of the dividend, as well as share repurchases. So we feel very good about our path forward here and look to continue on that path going forward. So we feel very good about it.
Vincent Alwardt Anderson - Associate
And just one last quick one. I know for the base assets, you're running the same no matter what. But if we do move into a slowdown next year, do you have any rainy day projects that you're already thinking about pulling forward maybe on U.S. Amines, maybe some derivative products that there's work that you can do in a weaker demand environment?
Erin N. Kane - CEO, President & Director
Yes -- but -- great question on U.S. Amines. And as we looked at that acquisition, one of the core value drivers was to be able to expand and grow that business and a number of projects are being formulated coming through engineering. And again, we've started to trigger some investment there, as well to be another avenue for us to continue to bolster our pipeline in the high-return growth and cost savings efforts.
And certainly, as we put a finer point on our planning for next year, we will look at anything that makes good sense. Certainly, the balance sheet is healthy for reinvestment into the business and preparing for -- certainly, if we were to come through a recessionary period and have a steep climb out of it, we'll be well prepared and positioned for that.
Operator
The next question comes from Charles Neivert with Piper Sandler.
Charles Nathan Neivert - MD & Senior Research Analyst
Good morning, everyone. You hear me okay? Okay. Great. Good morning. A couple of things. One, China has been, for lack of a better term, a bit of a pain for a lot of companies, not just so much in what they can sell to [them and such], but more that they're trying to keep their economy running a little bit and as a result, exporting to places they typically haven't exported. So we've seen product of theirs in Europe, we've seen it in South America. Have they run into -- have you guys run into them, as a competitor, and for instance, in South America on sulfate because they're apparently trying to sort of push the caprolactam. And then by the same token, are you seeing any caprolactam that typically doesn't leave China in markets that are showing up that might have some impact on pricing, whether you sell there or not, it may ultimately have a -- put some pressure on things. So have you seen anything from China on that front?
Erin N. Kane - CEO, President & Director
Yes. Certainly a lot of dynamics, as you point out here, Charlie. And if I take AS first, as you commented on, certainly, we have seen some significant increases reaching a record high in September. I think that caught a number of folks -- I wouldn't say [by but] surprise, but certainly, the numbers are very large when we look at what we believe the operating rates are and where normal inventories are. But that aside, they are supplying a far majority of the Brazilian imports already. I mean they have been increasing their share in Brazil over the past few years, particularly after the antidumping affirmative case here in North America.
We have also seen trade flows pointing that they've been moving resin materials into Europe as well. And certainly, their cost position and their price points provide an opportunity to move into that region, as well given the lower utilization of domestic producers there. And in a time, where Europe is structurally long in a number of our value chains, particularly in capro and resin, so it will be something we have to watch as we play out.
And certainly, that dynamic, while perhaps they're not bringing materials directly into North America, again, these are global markets with global pricing considerations. And that's -- that's something that we are seeing just as the trade flows are moving a bit here, having a consideration, as to where we can regionally price.
Michael Preston - CFO & Senior VP
And keep in mind, Charlie, as well, we have antidumping duties here in place with respect to China with ammonium sulfate. So that we don't see competition from China here in the U.S. China has been a big exporter, as Erin mentioned, to Brazil over a number of years, and we've been diversifying our exports to look for other opportunities in the export market outside of Brazil to sort of mitigate that. But -- so for AS, those are important considerations, I think you need to think about.
Charles Nathan Neivert - MD & Senior Research Analyst
On another front, a little bit more in the future. To the degree that you guys can do it, I mean, are you moving towards, I hate to use the word greener application or greener production. And the reason I'm asking is because we've seen some of the other companies we cover, who have actually managed to maintain market share over Chinese imports in certain markets, where they would compete because they have a far greener footprint and places, where it makes a difference like Europe, like the U.S., like some other countries, they've actually maintained share that on a price basis, they wouldn't have because of the greener aspects. Is that something you guys are looking at in terms of your product slate? Is it -- can you be like greener than somebody else and therefore, either maintain or take market share for those, who are really focused on that aspect of their business.
Erin N. Kane - CEO, President & Director
Yes. It's certainly a keen focus for us, as we head forward. I would share that we are starting with our life cycle analysis work, which is allowing us to clarify and have third-parties validate our footprint associated with our product lines in our integrated asset base. That will, one, help have the clarity of where we sit today, which we believe are -- is in a better position than perhaps the sort of benchmarks that are out there by third-parties in the value chain.
And then at the same time, working on a road map that will allow us to substantively decrease that footprint, and that's in the works, right? I think there are known projects that we can accelerate and look at, and that is part of our forward planning. And that's mostly what we're hearing at the start from our customer base is, help us understand the greenhouse gas footprint of the product lines, where you sit today, where we have the opportunity set. And as you point out, I believe that will allow us to have a strong position going forward with our customers.
I would note that when we think about CO2 emissions, we already do capture the vast majority of our CO2 emissions off of our Kellogg ammonia plant and have for [kindly] probably decades, right? It is beneficially captured and reused into known commercial applications for cold chain storage in the food and beverage market. And so we're also -- that's kind of a key factor going into our forward ability to serve customers in a way that is sustainable and with lower footprint.
Charles Nathan Neivert - MD & Senior Research Analyst
I think I must -- I missed it during the call, you said turnaround costs this year? Or is it CapEx -- is it -- turnaround cost this year were $50 million, that includes the $15 million a little bit. Next year is looking at what -- what was next year? You've been talking...
Erin N. Kane - CEO, President & Director
Yes. Next year, we are looking at...
Michael Preston - CFO & Senior VP
[28 to 33].
Erin N. Kane - CEO, President & Director
[28 to 33].
Charles Nathan Neivert - MD & Senior Research Analyst
Okay. Yes. That's what I had missed.
Operator
(Operator Instructions) The next question comes from David Silver with C.L. King.
David Cyrus Silver - Senior VP & Senior Analyst
So I'll have to stipulate upfront. I've been jumping around between a couple of calls. So I'll probably be making you repeat yourself. And actually, just right off the bat, I just -- I noticed that the e-mail and the earnings release had a few tweaks to them, and I gave them 2 thumbs up. I think it was more readable and a nicer presentation. Yes, so I'm just buttering up Adam because I drove more crazy this morning. So anyway, okay.
So first question would be about ammonium sulfate outlook. So in particular, I was kind of looking at the roughly flat year-over-year revenues and checking my price charts, and I think your volumes, ammonium sulfate volumes in the third quarter were down quite a bit year-over-year. And I'm wondering, first off, if you could confirm that?
And then second off, just I'm assuming it's going to be a sold-out post-harvest season or a very active pre-buy. Could you just -- how would you just characterize demand for ammonium sulfate and maybe your supply position heading into the fall fill season.
Erin N. Kane - CEO, President & Director
Yes. No, certainly, a few comments, maybe just to reiterate from before right? As we reset into Q3, certainly, we have the dynamics coming off of Q2 with the season there, reduced demand and the weather and that compress cycle, we saw inventory sort of has to move through the system, not just for our product lines, but really across the board for fertilizers. So as we reset across the industry for fill in Q3, clearly, that was at the higher end of our previous seasonality trends that we would have seen in recent past. But that said, we've been moving through the season as expected. So yes, volumes were down in the third quarter, but not unsurprising given the dynamics.
Certainly, demand continues to move forward, as we progress into the start of next year. So again, what we would say right now is the risk aversion that I commented on briefly before is not uncommon, right, for periods before farmers really need to purchase fertilizer, whether it's a fall buying surge for storage and application, exports activity, then kind of see a lull before another winter surge heading into the early part of next year. So I think all that we're seeing is not atypical. And then, of course, we had the turnaround in Q3 that would have impacted some volumes as well moving into the chain.
So really, as we head forward on your comments around pre-buy, we're really going to be watching over the next 30 days to this market emotion. It's really key to informing customers' interest in a pre-buy. We are here to support our customers and farmers and their success. And there's always advantages for them at year-end for whether it's tax planning and savings, as well as preparing for the season. But as we've shown in previous seasons, we can operate with a pre-buy or not, but we're going to take the cues from the market here. And we continue to address our order book.
Pricing has moved up a bit for -- through the fill, as we would have expected and really positioning into -- again, we think the fundamentals here are sound into next year, perhaps as others are already pointing out for seasons to come, given where global stock-to-use ratios are going to land, we really do have to continue to support food security around the world so.
Michael Preston - CFO & Senior VP
And Dave, just on the top line for ammonium sulfate in the third quarter year-over-year, although volume was down, revenue went from [$130] million in the third quarter of '21 to $132 million in the third quarter of '22. So market pricing more than offset the volume decline. Just to be clear.
David Cyrus Silver - Senior VP & Senior Analyst
Yes. No, thank you for clarifying that. I was mostly just trying to think about it from a volume perspective, but you're -- yes. No, thank you for clarifying that. The other thing I just wanted to ask would be raw materials and maybe any opportunities for, I don't know, strategic purchasing. But sulfur has been on a bit of a roller coaster, and it's settled out much lower this quarter than a couple of quarters ago and this is almost by the day, but when I look at natural gas prices yesterday's close, they were about as low as they've been in a long time. As you look ahead, I mean, how are you thinking about raw material volatility? And do you see any kind of opportunity to lock in maybe some more favorable pricing relative to what you've encountered year-to-date.
Michael Preston - CFO & Senior VP
Yes. No, good question. As we noted earlier, raw materials have come down a bit here in the fourth quarter relative to the third quarter. You did note that natural gas has come off, although natural gas is quite volatile depending on weather patterns, depending on the amount of injections and supply, as well as demand. So that's one to watch closely. Sulfur has also come off in the fourth quarter relative to the third. And we expect benzene to be down a little bit as well, whereas propylene might be a bit flat here in the fourth quarter relative to the third.
Now with respect to strategic purchases, there's limited, I would say, storage capability from a raw material perspective. We may have the opportunity to add additional volume on the periphery and take advantage of situations. But I would say it's more on the rounds, as opposed to the ability to significantly stock up.
But again, keep in mind, Dave, our -- half of our revenue, half of our business is on formula-based agreement. So even despite the volatility in the raw materials that we see, we get that covered through the formula agreements we have, really on more of a real-time basis with very little lag. So we feel very comfortable with that.
And where we have sort of spot-oriented business, we do get ahead of those -- the changes in the raws and price appropriately and feel we manage it on that basis very, very well, as you can see from our results when you look at them quarter-by-quarter. So that's how we manage it. We'll continue to look if there are opportunities to sort of lock in some pricing here and there. But generally, our business model is strong and conducive to perform well in a volatile raw material environment.
David Cyrus Silver - Senior VP & Senior Analyst
And I did have one more, and this is maybe picking your brains or getting your perspective on competition from Europe. And in particular, I think this really relates to the nylon chain, and I'm not really interested so much on the fertilizer side. But things have been quite volatile in Europe as on the cost side and now the economic outlook. And I'm wondering, in particular, as you think about kind of the supply-demand fundamentals on nylon and caprolactam products, just wondering what you're seeing out of Europe in terms of maybe some of these producers -- nylon producers that rely on highly integrated production models, multiple products and everything.
Coming out of the holiday season, let's say, in the third quarter, I mean, are you seeing them in the more -- larger, more strategic players? I mean, are they inclined to kind of ramp back up to as hard as they can to kind of maintain their market shares? Or are they maybe taking a little more cautious attitude based on maybe regional economic trends. So how competitive do you think European-based producers are going to be maybe over the next quarter or 2 just based on their regional economic outlook and the cost picture that they face?

Sure. And currently, in a number of value chains and when you notably point to caprolactam, the monomer and certainly nylon and the polymer, the energy dynamics, the input cost structure is regionally high there. That is why they have typically been operating at the lower utilization rates for a number of quarters. And while certainly, natural gas has come back down more recently, and we've seen some pickup in utilization, it is a, I would say, a structurally challenged region. It is structurally long and has been. It has relied on the ability to, I would say, export for full capacity utilization, and that is being certainly challenged at current with import pressures really now coming from China.
I would say that the strength of integration, so there are players that are more stand-alone that are players that are have full integration and have positions. And I think those that have that business model that full integration through most notably probably engineered solutions have high good contractual considerations that are focused on sustainability considerations like we talked about a little bit previously, are likely the winners over the long haul here.

The last question today comes from Vincent Anderson with Stifel.
Vincent Alwardt Anderson - Associate
I just -- I had one more. It feels like we haven't had a normal economic environment for the fourth quarter large assets owned -- large buyer assets owned negotiations since the trade case went through. What are you seeing? Is MMA going to even take significant commitments if we're staring down a recession? Just curious what's going on there right now.
Erin N. Kane - CEO, President & Director
Yes. I mean [we're] -- I'm cautious because we're in the heart of a lot of those conversations at current. And as you say, if you think about MMA tied through into its an application basis. But I think that the best way to think about it is probably just stability year-on-year relative to what we see right now.
Vincent Alwardt Anderson - Associate
That's probably because it's going to get for the time being. And actually, I just have one other one. It sounds like the answer is no for now. But have you seen any incremental interest in ammonium sulfate, just given your supply is not tied to the logistics issues on the Mississippi River right now?
Erin N. Kane - CEO, President & Director
Yes. I mean, again, we're focused into positioning for our customers and into the value chain. And as you say, we wouldn't have the same exposure relative to the barge movements. We do some rail to barge, but further north up the river. So I think that relative to those dynamics, we are in a different competitive state.
