Good morning, ladies and gentlemen, and thank you for standing by. Welcome to the Westlake Corporation First Quarter 2024 Earnings Conference Call. As a reminder, this conference is being recorded today, May 1, 2024. I would now like to turn the call over to today's host, John Zoeller, Westlake's Vice President and Treasurer. Sir, you may begin.

Thank you. Good morning, everyone, and welcome to the Westlake Corporation conference call to discuss our first quarter 2024 results. I am joined today by Albert Chao, our President and CEO; Steve Bender, our Executive Vice President and Chief Financial Officer; and other members of our management team. During the call, we will refer to our two reporting segments: Performance and Essential Materials, which we refer to as PEM, and Housing and Infrastructure Products, which we refer to as HIP. Today's conference call will begin with Albert, who will open with a few comments regarding Westlake's performance. Steve will then discuss our financial and operating results after which Albert will add a few concluding comments, and we will open the call up to questions. As a reminder, during the fourth quarter of 2023, we recorded a noncash impairment charge of $475 million related to the company's epoxy business as well as a $150 million charge to fully resolve certain liability claims. We refer to these two charges as the identified items in our earnings release and on this conference call. References to income from operations, EBITDA, net income, and earnings per share on this call exclude the financial impact of the identified items. As such, comments made on this call will be in regard to our underlying business results using non-GAAP financial measures. A reconciliation of these non-GAAP financial measures to GAAP financial measures is provided in our earnings release, which is available in the Investor Relations section of our website. Today, management is going to discuss certain topics that will contain forward-looking information that is based on management's beliefs as well as assumptions made by and information currently available to management. These forward-looking statements suggest predictions or expectations and thus are subject to risks or uncertainties. These risks and uncertainties are discussed in Westlake's Form 10-K for the year ended December 31, 2023, and other SEC filings. We encourage you to learn more about these factors that could lead our actual results to differ by reviewing these SEC filings, which are also available on our Investor Relations website. This morning, Westlake issued a press release with details of our first quarter results. This document is available in the Press Release section of our website at westlake.com. We have also included an earnings presentation, which can be found in the Investor Relations section on our website. A replay of today's call will be available beginning today, 2 hours following the conclusion of this call. This replay may be accessed via Westlake's website. Please note that information reported on this call speaks only as of today, May 1, 2024, and therefore, you are advised that time-sensitive information may no longer be accurate as of the time of any replay. Finally, I would advise you that this conference call is being broadcast live through an Internet webcast system that can also be accessed on our webpage at westlake.com. Now I'd like to turn the call over to Albert Chao. Albert?

Thank you, John. Good morning, everyone. We appreciate you joining us to discuss our first quarter 2024 results. For the first quarter of 2024, we reported net sales of $3 billion, EBITDA of $546 million, and net income of $174 million or $1.34 per share. Each was an improvement from our fourth quarter of 2023 results as we benefited from higher sales volume and lower feedstock fuel and power costs. Our results reflected a modest improvement from the destocking activity that occurred throughout 2023, as we saw higher sales volumes and pricing in many of our products beginning to improve. Our HIP segment performed exceptionally well, generating record first quarter EBITDA and margins while providing stability to our overall profitability and earnings with an asset-light, cash-generative business model. HIP sales volume grew an impressive 14% year-over-year as our leading positions enabled us to capitalize on resilient North American residential construction and infrastructure activity. This solid sales volume growth, combined with lower material costs and favorable sales mix, drove HIP's EBITDA margin to 25% in the first quarter of 2024, up from 20% in the prior year period. While our HIP segment continued to perform well, margins and earnings in our PEM segment reflected the weak global economic conditions. For the first quarter of 2024, our PEM segment reported lower net sales and margins compared to the first quarter of 2023, but we are encouraged by the sequential improvement in these metrics compared to the fourth quarter of 2023. The sequential improvement in PEM volumes from the fourth quarter of 2023 reflects demand beginning to recover and an end to the destocking activities we experienced throughout 2023. This improvement in demand is also accompanied by some pricing trends improving as we enter the second quarter. Meanwhile, the competitive advantage provided by our low-cost feedstock energy positions in the U.S. Gulf Coast expanded during the first quarter of 2024 due to both higher global oil prices and lower U.S. feedstock and power prices, which position us well to compete in export markets. At the same time, we are making progress on our cost reduction actions. In the first quarter of 2024, we achieved approximately $35 million towards our previously communicated $125 million to $150 million of targeted 2024 cost savings across the company, focusing on improving the global competitiveness of our epoxy and European operations. While we are confident in our ability to reduce costs to improve competitiveness, our epoxy business continued to be pressured by Asian export volumes priced below market-based production costs. As a result, on April 3, as a member of the U.S. Epoxy Resin Producers Ad Hoc Coalition, we participated in filing petitions with the U.S. International Trade Commission and the U.S. Department of Commerce, requesting the initiation of antidumping and countervailing duty investigations regarding imports of certain epoxy resins from five Asian countries. We remain proponents of the free and fair trade of goods on a global basis, but we also remain committed to working with trade groups such as the U.S. Epoxy Resin Producers Ad Hoc Coalition to use all the tools at our disposal to ensure a fair and level playing field in all the geographies in which we operate. Overall, I'm pleased with the progress that we are making to improve our position, our portfolio of businesses, and create value for our shareholders. I would now like to turn our call over to Steve to provide more detail on our financial results for the first quarter of 2024.

Thank you, Albert, and good morning, everyone. Westlake reported net income of $174 million or $1.34 per share in the first quarter on sales of $3 billion. Net income for the first quarter of 2024 decreased by $220 million from the first quarter of 2023. The year-over-year decline in net income was primarily due to lower average sales prices and margins in PEM, particularly in caustic soda, PVC resin, and epoxy resin, which were partially offset by improved sales volumes, lower materials costs, and lower restructuring costs in HIP. When compared to the fourth quarter of 2023, net income, excluding identified items, increased by $81 million in the first quarter, primarily due to higher sales volumes driven by an uptick in seasonal demand and strong market growth, driven by our cost-saving actions and lower restructuring costs. For the first quarter of 2024, our utilization of the FIFO method of accounting resulted in a favorable pretax impact of $31 million compared to what earnings would have been reported on the LIFO method. This is only an estimate and has not been audited. Before I discuss the details of our segment results, I want to provide some high-level thoughts on the quarter. The record first quarter results in our HIP segment demonstrate the progress we have made in integrating and optimizing the acquisitions of the last few years. HIP's strong 14% year-over-year volume growth in the first quarter in part reflects the benefits of the broad branded product set, combined with a much wider geographical footprint, driving cross-selling of our products through nationwide distributors going into home construction and remodeling. The record first quarter EBITDA margin of 25% was supported by our cost savings initiatives, production optimization activities, and lower materials costs. These cost savings go well beyond typical acquisition synergies as we implement our efficiency-focused manufacturing culture and increased automation within our operations. Overall, we are very pleased with HIP's asset-light, cash-generative business model and solid EBITDA margin. We hope that you will join us on June 13 as we host a HIP-focused investor teaching event in New York to share more about the exciting progress and opportunities we are seeing in this important segment. Turning to our PEM segment, our first-quarter results reflect the challenging global industrial and manufacturing macroeconomic environment. That said, we are encouraged by the improving trends for both sales volumes and pricing as we enter the second quarter. We took proactive steps to improve the financial performance of this segment, including progress toward our company-wide $125 million to $150 million cost savings target for 2024 and our efforts to halt the flood of low-priced Asian imports in certain product categories. Moving to the specifics of service segment performance, our Housing & Infrastructure Products segment produced record first-quarter EBITDA of $264 million on $1 billion of sales. EBITDA increased $59 million year-over-year due to a solid 14% increase in sales volumes, improved product mix into higher-margin products, lower materials costs, and acquisition synergy and other cost-saving benefits. Notably, HIP achieved an important milestone this quarter with trailing 12-month EBITDA exceeding $1 billion for the first time. This achievement is a testament to the hard work of our HIP colleagues and the synergies achieved across our businesses. When compared to the fourth quarter of 2023, HIP segment sales of $1 billion rose 10% driven by a 12% sequential increase in sales volume, which more than offset a 2% decrease in average sales prices. Housing product sales of $879 million in the order increased by $84 million due to solid sales volume growth, particularly in Pipe & Fittings and Siding & Trim. Infrastructure product sales of $165 million in the first quarter of 2024 increased by $14 million from the fourth quarter of '23 due to double-digit sales volume growth in our compounds resin business. HIP's EBITDA margin of 25% set a record for the first quarter and was the second highest for any quarter. The margin expansion from 20% in the prior year period was primarily due to lower materials cost and higher sales volumes, while the sequential improvement from 18% in the fourth quarter of '23 was due to higher sales volume, improved sales mix, and lower restructuring costs as we optimized our manufacturing footprint. Moving to our PEM segment, first-quarter EBITDA of $253 million was below first quarter of 2023 EBITDA of $615 million due to lower average selling prices, particularly for caustic soda, PVC, and epoxy resins. On a sequential basis, PEM's segment EBITDA of $253 million in the first quarter increased by $52 million from the fourth quarter of 2023 as a result of higher sales volumes, particularly for PVC and epoxy resin, lower feedstock, fuel and power costs, and our cost savings actions. As Albert mentioned, as we entered the second quarter, we are encouraged by the improvement in recent pricing trends and sequential sales volumes growth, reflecting an end to the destocking we experienced in 2023 and reduced competition from low-priced Asian imports in Europe as a result of shipping disruptions in the Red Sea. Shifting to our balance sheet, as of March 31, 2024, cash and cash equivalents were $3.1 billion, and total debt was $4.9 billion, with a staggered long-term rate debt maturity schedule. For the first quarter of 2024, net cash provided by operating activities of $160 million was impacted by an increase in working capital as we grew our inventories and accounts receivable resulting from the seasonal uptick in demand I previously mentioned. We will continue to look for opportunities to strategically deploy our balance sheet in order to create long-term value. Now let me provide some guidance for your modeling. As we view demand and prices, we continue to expect 2024 revenue in our Housing and Infrastructure Products segment to be between $4 billion and $4.4 billion, with an EBITDA margin around 20%. Westlake continues to execute with financial and operational discipline as we invest throughout the business cycle, and we expect our total capital expenditures to be approximately $1 billion in 2024, which is unchanged from our earlier guidance and is similar to our depreciation and amortization run rate. As a reminder, this includes cost for the planned turnaround of our Petro 1 ethylene unit scheduled to begin in the second half of this year, that is projected to last approximately 60 days. We will continue to target the $125 million to $150 million of cost savings in 2024 with roughly $35 million achieved in the first quarter. For the full year of 2024, we expect our effective tax rate to be approximately 23%, and we expect cash interest expense to be approximately $160 million. Now let me turn the call back over to Albert to provide a current outlook of our business.

Thank you, Steve. Our first quarter results, once again, demonstrated the value of our vertical integration strategy and the diversity of our segments in reducing the volatility of our overall earnings. Our HIP segment continues to perform well, supported by favorable demographic trends, lower material costs, the strong value of brands, and our own cost savings and cross-selling initiatives. Meanwhile, results in our PEM segment reflected the macroeconomic backdrop of a slow but steady post-COVID economic recovery in Asia and mostly improving ISM manufacturing index readings in the U.S. and Europe. While recent trends over the past year have been challenging, we continue to have a positive view for our long-term demand supported by the growing global need for clean water, transportation, renewable energy, packaging, and consumer goods. Our efforts to help our customers achieve their sustainability goals contributed to our sales growth in the first quarter. For example, sales volume for our pivotal post-consumer polyethylene resin increased sequentially by nearly 30% from the fourth quarter of 2023 as we are seeing increasing consumer adoption of the product, particularly for consumer trash bags to meet new regulations for post-consumer material usage. Our GreenVin PVC in Europe, now representing a significant portion of our European PVC sales, offers customers green PVC products. These are just a few examples of innovative products Westlake has developed to improve customers' environmental footprint and support our long-term sales growth rate. At the same time, we continue to make investments in our plants and manufacturing processes to reduce impact on the environment. Before we open the call for your questions, I want to review our thoughts on our current outlook. Overall, global macroeconomic conditions remain sluggish with restrictive monetary policy in place in many geographies and lingering high rates of inflation weighing on consumer demand. In spite of the challenging backdrop, we have continued to invest in innovative products to meet our customers' needs and deliver product solutions with unique properties and characteristics as the markets evolve. Results in our PEM segment are supported by our key strengths, namely our global scale with highly integrated, structurally advantaged North American assets that benefit from low-cost feedstock in our research and development facilities around the world that are developing products with solutions to meet customer needs. We believe that our HIP segment is positioned to perform well in this environment supported by positive demographic trends and the need to rebuild housing stock and infrastructure in North America following years of underinvestment. These secular tailwinds combined with our strong branded product offerings, nationwide service, and cross-selling opportunities should continue to drive sales volume growth, while our cost-saving and automation initiatives support continued solid margins. While we expect global economic conditions to slowly improve over the course of 2024, we are fortunate to have a strong investment-grade balance sheet with net debt below one-time trailing 12 months EBITDA and no significant near-term debt maturities. We view this solid financial position as a significant asset to create further long-term value for our shareholders as we continue to evaluate ways to deploy our balance sheet as opportunities arise. Thank you very much for listening to our first quarter earnings call. I will now turn the call back over to John.

Thank you, Albert. Before we begin taking questions, I would like to remind listeners that our earnings presentation, which provides additional clarity into our results, is available on our website and a replay of this teleconference will be available two hours after the call has ended. Liz, we will now take questions.

Our first question comes from Patrick Cunningham at Citibank.

How much of the volume gains in the quarter would you attribute to share gains? How important has cross-selling been and increased offerings versus maybe your larger homebuilding customers gaining share themselves and you benefiting from that additional volume opportunity?

Yes, Patrick, it's Steve. We've been able to really participate and grow with our customer base. As we sell into the distribution channel, those distributors are well aligned with those large nationwide homebuilders, and as the nationwide homebuilders continue to gain market share, we're participating with their growth. So we continue to see very good progress really in partnering with those nationwide builders, as they continue to gain market share, and we're participating in that market share growth along with them. Certainly, the brand offerings that we have also have very good penetration in the repair and remodeling market, so it's not entirely all in the new construction arena.

Got it. And then just on the sales and margin guide for HIP that you maintain. It seems a bit puzzling, just in the context of the particularly strong first quarter; are there additional price cost headwinds which you're baking into that outlook? Maybe what's your outlook for volumes for the year?

Yes, certainly. We're all well aware that we still have an elevated interest rate environment. And certainly, we understand that many of these national homebuilders are providing various sales incentives. So as we see the year progress, if we see the improvements in interest rate outlook and continue to see the strength that many of these homebuilders speak to, we'll continue to assess the kind of guidance that we provide. But right now, we think that this is prudent. But we do think that we head off to a wonderful start and really look forward to continuing the trajectory that our HIP business is progressing on.

The next question comes from Frank Mitsch from Fermium Research.

Yes. If I could just follow up on that last question in terms of maintaining the guide on HIP, how would you describe the visibility on your order books in that business? Do you have it through the second quarter? Is it into the third quarter? How would you describe your visibility there?

Yes, Frank, good question. We do have good visibility into the second quarter. And I would say the backlog continues to remain quite strong. We see it not only in our Siding & Trim business but also in our Pipe & Fittings business, which are very good leading indicators in terms of the strength that we expect to see as we get into the second quarter with that HIP business. Of course, as we see a pull on Pipe & Fittings, as I say, it's a really good indicator of the construction activity we see in new construction going forward into the second quarter.

I'm excited about the date on June 13. Could you discuss the effect that the Red Sea shipping challenge had on your European operations? What benefits did you observe, and how sustainable do you believe those benefits are? It would be helpful to hear more about Europe.

Oh, yes, I think the Red Sea situation improved somewhat. And while during the first quarter, we did see a slowdown of imports to Europe. But the situation still goes out, and I think the tech on shipping vessels continues.

So the benefits for your localized European production units should continue through the second quarter at this point, correct?

Yes, I believe that volume, particularly in the second quarter, tends to be among the highest of the year, so we can expect to see some improvement in volume.

The next question comes from Turner Henricks with Morgan Stanley.

It's actually Vincent Andrews from Morgan Stanley. If I could ask you about the PEM outlook for the second quarter, it looks like you're anticipating sort of a flat outcome. Could you help us understand what your expectations are on volume and price and, in particular, the caustic soda market? Are you not anticipating any improvement? It looks like there was a price increase for April, though some of the trade presses contextualize that as maybe not being durable. So I would love to hear your outlook here.

Yes. I think, again, because of the increased demand in construction PVC in general, globally, there's more caustic available. So as we move into the second and third quarter, we will see a leveling off of the price increases we had, as you mentioned, between the first four months, probably $35 turn off in the U.S. price increases, and we see export prices improving globally somewhat. So we think that the price will be more or less flat. I think some of the consultants are saying depending on how the general global economic condition fares out in the second half of the year, if that improves, the caustic price will improve; otherwise, it will be pretty stable at today's levels.

Okay. And then as a follow-up, Albert, just on the M&A environment, you obviously have a big pile of cash there. And anybody else that might want to buy something is still facing unattractive borrowing rates, and who knows how long those borrowing rates will stay where they are. But I'm just wondering if we're getting to a period of time where maybe you're really advantaged as a buyer being able to be a cash buyer; are you seeing anything opening up for you on the M&A front as we move through the balance of this year?

Yes, Vince, I would say that as we continue to look at opportunities across both the chemical side and the building products side of our business, we're going to continue to be very thoughtful about how we deploy capital. Certainly, we are very focused on the return. And as you know very well, we've been very focused on making sure that throughout the cycle, any investment we're making is going to give us that risk-adjusted rate of return. So yes, we do think that the capital position, the strong balance sheet we have, provides us with really good opportunities, but it doesn't really change how we think about investing over the cycle in the businesses, but we'll continue to have a very pragmatic and very thoughtful approach looking at both sides of the business to continue that investment thesis.

The next question comes from Aleksey Yefremov with KeyBanc.

Albert or Steve, on Slide 6, you list the key categories of your products: siding, trim, pipe, etc. Can you just provide sales performance commentary? Do any of the categories stand out to you so far this year as particularly strong or not?

Yes. I would say, Aleksey, that those that I spoke to really were, as I say, the Pipe & Fittings and Siding & Trim are those that we continue to perform very well in this business. I think they're really strongly positioned in the marketplace with the competitors. We have a strong positioning in our Fittings business and in our Pipes business, and of course, Siding & Trim. We continue to see really good improvement in the Boral businesses that brought roofing materials and windows as well as decorative stone. So I would say that acquisition has really continued to perform well. And you can see from the results that those branded products continue to really be good selling points with our nationwide customer base. But I would say those that we called out specifically in this quarter, the Siding & Trim and the Pipe & Fittings were those that really strongly performed.

Understood. And then maybe more of a big-picture question. On your HIP business, you're obviously looking for additional product line acquisitions, but you talked before about potential opportunities to unlock the valuation discount for the business. As you think about those options, is this stock merger with another publicly traded or another large building products company an option that would separate the chemical business from the building products?

Yes. I mean as we think about opportunities to build out the businesses, looking at acquisition currencies, whether they're cash or equity-based are all issues that would be well considered. It's just a matter of what the value proposition is and really what is of interest to the other side. So those considerations and that kind of currency are freely available to us. It's just a matter of what is interesting and value-oriented to the other side of the table.

The next question comes from Hassan Ahmed with Alembic Global Advisors.

I wanted to discuss some of the qualitative aspects you mentioned regarding your guidance and translate that into a numerical context as well. You achieved $546 million in EBITDA in Q1. It seems that destocking is behind you, and we are entering a period of seasonal strength. There appears to be both volume and pricing momentum. Is it reasonable to consider that based on the $546 million annualized, which amounts to $2.2 billion, for 2024, you are likely to exceed $2.2 billion? Is that the correct way to think about it?

Hassan, as we think about guidance, as you know, we don't provide kind of the consolidated company guidance though we do provide it for the building products business. And I think as you can see from our prepared remarks, that pricing seems to have stabilized at this point across the chain. And that's, I think, very important. But as we think about the outlook, the questions still remain in terms of how we see the pricing trends in the back half of this year and volume trends. So we have a constructive outlook, as you can see, but we're not providing any numerical guidance for Westlake on a consolidated basis.

Fair enough. Fair enough. And just changing gears to the epoxy side of the business. One of your competitors that actually separately discloses their epoxy results. From those results, it appeared that epoxy is kind of turning a corner; EBITDA turned positive for the first time in a couple of quarters there. So could you talk a bit about what you guys are seeing in terms of the market dynamics there, the supply-demand fundamentals there in a sort of business going the way it's going scenario as well as in a scenario where these antidumping cases that are being brought about actually go through?

Yes. We are seeing a slight improvement in epoxy prices across all the regions in the U.S., Europe, and Asia. And we are seeing some demand improvement as well. And also, we're seeing a bit less imports into the U.S. and Europe. So things are looking better, but I think the dynamics still have a lot happening around renewable energy with windmills and with coatings, which associate with construction infrastructure. So I think the general economy globally would impact the global demand for epoxy. We are seeing some signs of improvement. Again, the dynamics, the different Asia is weakest, and then Europe is doing better, while the U.S. is the better region generally speaking among these three regions, but things could change. As Steve mentioned, we don't know the second half with so much uncertainty from inflation, interest rates, geopolitics, and elections. But I think on a longer-term basis, we are very optimistic about both HIP and PEM segments, as we alluded to in our comments, and we work to reduce our costs, strengthening our positions in all these products, including M&As. We are open to all ideas on M&A as well. Our goal is to really earn above our cost of capital, and with our financial asset base, we can do deals that make sense to us.

And the next question comes from Mike Harris at Goldman Sachs.

And I have a question on HIP. On Slide 6 in the earnings deck, you show a U.S. TAM of roughly $40 billion. And looking at the current annual HIP sales would suggest that even though you have a #1 or #2 market position for the most part, you still only serve about 10% of that TAM. If so, how should we think about the other 90%? I mean, can you pick up meaningful market share with the current portfolio? Or would it require more M&A? And if more M&A, how would you rank your HIP just in the list of growth opportunities?

Yes, Mike, good question. And the answer is you've seen that we are continuing to look at broadening the overall portfolio in our HIP segment. The acquisition of Boral and Alaska are really good examples of ways we're adding to that portfolio. This broad total addressable market is one that we think has good opportunity. In our prepared remarks, we spoke about the underinvestment in both infrastructure and in housing. When you think of the housing market being probably a 40-year age average, it has a great opportunity to continue to need both repair and remodeling and new construction activities. The infrastructure bill provides great opportunities for us to continue to invest and grow in that area. As you think about the way we can grow and address this large market, the answer is we can address that with our current portfolio, but I would expect to add additional pieces to the portfolio to address the growing needs that we see in the overall marketplace. So this is why, when we think about acquisition orientation, we're looking to add important pieces to the overall building products portfolio that we have in HIP.

The next question comes from Kevin McCarthy of Vertical Research Partners.

In your HIP segment, did your first quarter EBITDA margin of 25% come in better than you would have thought three months ago or on par? If it was better, what were the most important drivers of the upside margin variance?

Kevin, it was stronger than I would have guessed that we had a very strong start to the year. And I would say in the first quarter, the strength that we saw in markets beginning to kind of restock levels and the construction activity in the first quarter continue to be quite strong. As I mentioned, we've seen many of our partners that are these nationwide homebuilders. And while we service them through distribution channels, continuing to have them grow market share; and we're participating in that market share growth with them. I think that speaks to the strength that we've seen in the overall business and the business strategy of penetrating these markets with our branded products. So I would say, yes, we had a very strong quarter and stronger than I would have guessed if you'd asked me earlier in the fourth quarter.

Okay. And then if I may shift gears to your chlor-alkali and vinyls businesses. Can you comment on your operating rates in the first quarter? And as you look ahead to the second quarter, how do you think those operating rates might trend relative to normal seasonal patterns in those businesses?

Yes. I think in chlor-alkali in the first quarter was probably in the high 70s, and there were also turnarounds going on. And partially one of the questions earlier was that when the turnaround is over, the operating rates will be higher. And hence, there's more supply. So depending on the global demand for products, as you know, U.S. exports around 20-odd percent of its products. So the operating rates, we would expect to be higher in the second quarter than the first quarter.

The next question comes from Michael Sison at Wells Fargo.

A nice start to the year. For polyethylene, there were some price increase announcements out there for April. And I guess for May potentially as well. How do you feel about supply and demand for polyethylene these days? And do you think those price increases can be supported?

Yes. We had a price increase earlier in the year, and I think the industry is looking for a $0.03 price increase in April as well as a $0.03 price increase in May. The demand has been quite good domestically and for export in the U.S. And April is not over yet. So in terms of negotiations with pricing, we will tell you in a few days how that goes.

Got it. And then for PEM in total, on a sequential basis in Q2, I just want to make sure I understand. You are seeing sort of a seasonal lift into the second quarter sort of in total. And then, I mean, do you think your volumes will still continue to grow year-over-year as it did in the first quarter?

Yes. So Mike, as we mentioned in our prepared remarks, yes, we're continuing to see the volume strength that we saw in the first quarter continue on into the second quarter. And certainly, that is very supportive of our outlook as we go into the year, but it's hard to see what will transpire in the back half of the year. But I would say that as we enter the second quarter here and see the volumes continue to be constructive and pricing has certainly across, whether it be in polyethylene, caustic, or PVC. We've seen price traction in the first quarter, which continues to be positive in terms of overall results as we look into Q2. But it is hard to then look that far forward into the back half of '24. But we do see positive signs at this stage for the second quarter.

The next question comes from Josh Spector of UBS.

I wanted to ask specifically on the HIP margins and looking at the second quarter. Typically, margins are up sequentially and I understand the prudence on the year. I just wanted to check to make sure there wasn't anything or see if there's anything discrete that we should be thinking about, either PVC pricing adjustments or something else that will lead to an abnormal sequential movement in margins in HIP?

As we move into the second quarter, you are correct that some of the price increases we implemented in the first quarter are being passed on in our building products. Typically, the second and third quarters are our strongest for volume. Given our solid backlog, we are optimistic about being able to implement those cost increases in our products. Overall, we have a positive outlook for the second quarter regarding the building products segment of our business.

Understood. That's helpful. And just on the infrastructure side of the business, you've had pretty good growth sequentially, that was down year-over-year. And I mean some of the non-res indicators are still up, but softening I guess. How do you see that part of the business trending relative to the more housing exposure to the other part of the segment?

I would say the infrastructure aspect of our business remains strong. The backlog in the Pipe & Fittings sector looks promising, which is a positive sign for the exterior construction activities of our Westlake Royal businesses. The recent infrastructure bill, which includes $55 billion for various needs in the U.S., should significantly benefit us. We are well-positioned to take advantage of this government investment. With our current backlog, we maintain an optimistic outlook for the second quarter in our infrastructure business.

We have time for the remaining questions. The next question comes from Salvator Tiano with Bank of America Securities, Inc.

Yes. Firstly, I wanted to understand the dynamics for HIP in Q2. When you look at the past couple of years, it seems that due to seasonality, there is typically a $30 million to $40 million EBITDA boost in Q2 compared to Q1. Considering your strong order backlogs, should we have the same expectation this time? Or was there any business pull forward in Q1?

No. I think we've seen a kind of continued strength that we saw at the tail end of the year. So obviously, there's a seasonality to the business that we normally see. I think the first quarter is not a pull forward, but a continuance of the demand picture of the underinvestment both in infrastructure and in housing. So as I mentioned, the strength that we're seeing with our nationwide homebuilder partners, they're continuing to grow market share, and that isn't necessarily a front-loading—it's just simply being able to grow with the market as those nationwide homebuilders continue to grow their market share. We're participating in that. And that's not really a pull forward per se.

Okay, perfect. That leads me to my second question. If we continue to see positive trends in Q2 and considering what you've reported, along with your unchanged guidance for the segment, it seems that you expect to generate significantly less than $200 million in EBITDA in each of the last two quarters of the year. This would represent a notable decline, primarily related to margins. What do you believe will drive this expectation? Will it be a substantial decrease in volume or a significant narrowing of price costs?

Yes, as I mentioned, as we look into the second half of the year, it's harder for us to see the entire third and fourth quarter. If we do continue to see the strength we've seen so far, we'll assess our guidance going forward. But at this stage, we haven't adjusted our guidance. But as I say, if we continue to see strength in this business, we'll assess the second half of the year as we approach that. But I would say we continue to see good strength into the second quarter as we progress here. The headwind really would be in being able to push through some of these PVC resin prices and our downstream building products businesses. But given the strength in the backlog we see, we think we'll have good success on that front.

The next question is from Matthew Blair at TPH.

I wanted to ask about Slide 5, especially the comment regarding the strong demand you're seeing for large diameter pipe. Are there any numbers you can share around that? And I guess, is the implication there that some of the homebuilders are starting new developments, putting in the initial infrastructure but really haven't started on the actual housing construction yet?

The infrastructure sector remains strong. Our pipe and fittings business has a solid backlog, which is driving growth in our exteriors business, specifically with Westlake Royal. We are confident in the performance of our Pipe & Fittings division, which has already shown strong results in the first quarter, and we anticipate this will continue into the second quarter. While we do not disclose specific volumes for each subsegment of our HIP business, we are observing robust strength in this area.

Sounds good. And then you mentioned that in HIP areas like Pipe & Fittings as well as Siding were especially strong. What areas are you still looking to catch up on? What areas are a little bit softer right now?

So certainly, as we think about the businesses that have stronger margins, those that we just called out, I'd certainly say the windows business certainly is a bit more challenged than I would say the Siding & Trim business, which we called out as having very good strength and Pipe & Fittings having very good strength.

The next question comes from Arun Viswanathan of RBC Capital Markets.

I wanted to get a clearer picture of the expected growth from Q1 to Q2. It seems that HIP increased by around $100 million from Q4 to Q1, and PEM rose by about $50 million. Looking ahead to Q2, it appears that HIP may see an increase of approximately 15% sequentially, with PEM potentially following a similar trend, and possibly even more for HIP. How do you see this playing out? Volume seemed to be a key driver in the last quarter, and do you anticipate a similar increase in volume heading into Q2?

Yes. So Arun, as we think about the Building Products business, I would say volume continues to be good. As I mentioned several times, we have a good backlog. We will be looking to try to push through these PVC price increases that we achieved in the first quarter through that chain. And so that remains really the headwind in terms of being able to expand margin as we go forward with this higher volume.

And what about PEM, sorry, as you go into Q2?

Yes. Certainly, you've seen the tailwind we've seen and pricing traction both in PVC and polyethylene as well as in caustic. And certainly, the strength that we've seen with those price improvements over the course of the first quarter, we hope to continue. Prices seem to have stabilized at these elevated levels. And as we look forward, there's really—if we see a good reason to think that those prices will remain at these elevated levels now that we've achieved that improvement in pricing across those products.

As a follow-up, what is the typical backlog for HIP? Is it measured in weeks or months? How much visibility do you have on this? If you do have a significant amount of visibility, should we expect the EBITDA margin for HIP to be in the range of 20% to 25% more consistently? I note that you've been above the 15% to 20% range for several quarters now.

So Arun, we can typically look at a couple of months in terms of order in the order books. Of course, at any point in time, they can cancel orders. But the guidance that we provided of approximately 20% is really kind of where we are at this stage, and we'll update that guidance as we progress through the course of the year.

And we have time for one more question. Welcoming back to the stage for a question, we have Salvator Tiano with Bank of America Securities, Inc.

I just want to also ask a little bit about epoxies. And if you can refresh a little bit about your exposure to more commodity products versus downstream composites and systems? And how has that changed in the past few years since you made the major acquisition, I think it was three years ago?

Yes. I think we're covering most of the epoxy applications including coatings, electronics, windmill blades as well as aerospace. So all these areas, we are participating both in the more commodity grades as well as more specialty grades. And so I think it's just in the past with the unfair price Asian imports has impacted the margin of European and U.S. markets. But I think, as we said earlier, we are seeing signs of improving pricing and demand is coming back slowly. So we're seeing some improvement already.

And please stand by, we will take one more question. Final question from David Begleiter at Deutsche Bank.

Albert, just back on the HIP margins. The last three years, HIP margins have increased from Q1 to Q2. I believe you've also been at various times pushing through higher PVC prices. So why would this year be any different in terms of margins increasing from Q1 to Q2 in HIP given the seasonally stronger demand even with pushing through some higher PVC prices?

So David, as you think about the housing starts that we've seen, we're continuing to see the homebuilders be constructive in their outlook for starts, and we continue to seek positive signals in permits. But we also recognize that affordability remains an issue. And so we're really trying to be thoughtful about making sure that we can get the value for the product we're pushing through, but we recognize there is only a certain speed in which we can push through each product downstream into our fabricated products. So it's an issue of the timing of being able to push through these prices and not are we able to push through these prices. It's just a matter of timing.

Got it. And lastly, Albert, there is some new capacity from PVC coming on stream this year from other players. How do you foresee that impacting the market, if at all, as most of this is geared for the export market?

Yes. I think with the lower big stock position, both for making ethylene, 50% of PVC's ethylene. I know 50% is chlor-alkali, which is very heavy on power and natural gas feedstock. So with a low feedstock and power position, I think our industry is well positioned to participate in the global PVC market around the world, and the U.S. exports around high 20, low 30 percent of our production. I think the U.S. industry, with a great cost position, will continue to participate in the global markets.

At this time, the Q&A session has now ended. We'll turn it over to John Zoeller for any closing remarks.

Thank you again for participating in today's call. We hope you will join us again for our next conference call to discuss our second quarter results.
