At the conclusion of the company's presentation, we will open the call for questions.

Thanks, Kim, and thank you all for joining us for our review of our first quarter 2024 results. Turning to Slide 7. The year is off to a good start as our first quarter adjusted EBITDA of $62 million surpassed our internal expectations. Business conditions continue to normalize and operating efficiencies improved across all platforms. Both the general engineering and automotive end markets are off to a faster start than expected at the beginning of the year. Aerospace and high-strength, while stronger year-over-year, were softer than our original expectations. Our efforts to control costs and implement our metal sourcing strategy gained traction in the quarter. As we move through the balance of 2024, we expect to continue to make progress on these initiatives, positioning the business for the next phase of our strategy with the full commissioning of the roll coat #4 investment at our Warrick packaging facility in 2025. I'll now turn the call over to Neal to discuss the quarter in more detail, and then I'll be back to discuss our outlook.

Thanks, Keith. Good morning, everyone. I'll begin on Slide 9 with an overview of our shipments and conversion revenue. Conversion revenue for the first quarter was $367 million, a decrease of $2 million or 1% compared to the prior year period. Looking at each of our end markets in detail, aero and high-strength conversion revenue totaled $137 million in the first quarter of 2024, reflecting a 12% improvement on an 8% increase in shipments over the prior year quarter. The improvement in conversion revenue reflects a mix of higher-priced products along with growth in shipments. Packaging conversion revenue was $118 million, a decrease of 11% year-over-year, due primarily to a 7% reduction in shipments of higher-priced coated food products, driven by the expected first quarter 2024 destocking. General Engineering Products conversion revenue was $80 million, up slightly year-over-year on a 2% increase in shipments, partially offset by a lower value mix. And finally, automotive conversion revenue was $31 million, which was relatively flat compared to the first quarter of 2023, driven by a 4% reduction in shipments, offset by improved pricing. Additional details in conversion revenue and shipments by end market applications can be found in the appendix of this presentation. Now moving to Slide 10. Reported operating income for the first quarter of 2024 was $33 million after adjusting for operating non-run rate items of approximately $1 million, adjusted operating income was $34 million, up 70% year-over-year on improved operating results, offset by a $2.5 million increase in depreciation. Our effective tax rate continues to be in the low to mid-20% range under current tax regulations. We anticipate that our 2024 cash taxes for foreign and state taxes will be in the $3 million to $4 million range with no US federal cash tax until we consume our federal NOLs, which as of year-end 2023, were $101 million. Reported net income for the first quarter of 2024 was $25 million or $1.51 net income per diluted share compared to net income of $16 million or $0.99 net income per diluted share of the prior quarter. After adjusting for approximately $1 million of operating non-run rate items previously mentioned and other non-run rate income of $11 million, primarily related to insurance settlements from prior year claims, adjusted net income for the first quarter 2024 was $17 million or $1.02 adjusted net income per diluted share compared to adjusted net income of $7 million or $0.42 adjusted net income per diluted share in the prior year quarter. Now turning to Slide 11. Adjusted EBITDA for the first quarter of 2024 was $62 million, up approximately $16 million or 34% from the prior year period. Adjusted EBITDA as a percentage of conversion revenue improved approximately 430 basis points from the first quarter of 2023 to 17%. The improvement in adjusted EBITDA was primarily the result of improved operating efficiencies and cost controls in the business, as well as timing of certain annual planned maintenance events and lower freight costs, which was partially offset by higher employee benefit and incentive costs. Now, turning to a discussion of our balance sheet and cash flow. On March 31, 2024, total cash of approximately $102 million and approximately $517 million of borrowing availability on our revolving credit facility, provided total liquidity of approximately $619 million. There were no borrowings under our revolving credit facility during and as of the quarter end, and it remains undrawn. On March 31, 2024, our net debt leverage ratio continued to improve to 4.2x, as we continue to make progress towards our target leverage ratio of 2x to 2.5x. Turning to capital allocation. Capital expenditures for the first quarter totaled $30 million. This is lighter than anticipated, attributed primarily to the timing of payments of invoices related to our roll coat 4 project, which remains on track for commissioning later this year. Our full year 2024 capital expenditures are still forecasted to be in the range of $170 million to $190 million. On April 15, we announced that our Board of Directors declared a quarterly dividend of $0.77 per common share, underscoring the continued confidence our board and management team have in our long-term strategy to improve our profitability and increase stockholder value. And now, I'll turn the call back over to Keith to discuss our outlook.

Thanks, Neal. Now, I'll turn to our outlook for the fiscal year of 2024. Beginning with aerospace on Slide 13. We have experienced strong momentum over the last several quarters in aero and high-strength market demand that has carried over into 2024. However, given recent developments, we are taking a more cautious outlook on expected build rates for the balance of the year for domestic large commercial jet production. Our long-term outlook for continued strong demand for these platforms remains unchanged. The diversity of our customer base and our ability to be agnostic on platforms is by design and positions us well regardless of market conditions. We remain a key supplier to all customers in the large commercial jet segment and maintain strong positions in other key segments of the aero and high-strength markets, including defense, space, business jets, and other industrial high-strength applications. Based on current expectations, we now expect aerospace and high-strength shipments and conversion revenue to be flat year-over-year for 2024 versus 2023. Now, turning to packaging on Slide 14. Destocking from our food packaging customers ended in the latter half of the first quarter. Based on conversations with our customers, we now expect our shipments to continue to improve from these levels throughout the balance of 2024. Additionally, our new roll coater installation is progressing according to plan. The project remains on budget and is set for completion by the end of this year, with production expected to begin in 2025. To date, we have a substantial portion of this capacity already committed, with discussions well underway for the balance. Accordingly, we continue to expect our packaging shipments and conversion revenue to improve by 5% to 7% year-over-year in 2024. Now, turning to general engineering on Slide 15. We began to see an increase in order rates for all general engineering products, with destocking ending late in the first quarter, as supply levels are now aligned with current demand trends. We continue to expect improving demand for our general engineering products, as we progress throughout the year, with our 2024 shipments anticipated to improve by approximately 5% to 6% year-over-year. However, we continue to forecast modest price compression in our outlook, as demand recovers and therefore expect the resulting general engineering conversion revenue to be flat to up 1% compared to 2023. Next, I'll turn to automotive on Slide 16. Demand remains flat to slightly up versus last year's levels, as higher build rates for trucks and light vehicles in North America drove a steady recovery into 2024. Further, recent price increases initiated late last year are anticipated to hold. As a result, we expect our 2024 auto shipments and conversion revenue to increase in the 3% to 5% range versus 2023. Now, I'll go into our summary outlook, turning to Slide 17. For the full year 2024, we expect demand will continue to improve across most of our end markets. As a result, we continue to expect conversion revenue to improve in the 2% to 3% range over 2023. Additionally, we continue to expect approximately 70 to 170 basis points of EBITDA margin improvement year-over-year. In summary, we are off to a strong start to the year and continue to make solid progress on our growth initiatives, which position us well as we implement the next stage of our growth strategy in 2025. Looking ahead, our focus remains on successfully executing our revised metal sourcing strategy at Warrick, managing costs and improving operating efficiencies across all our businesses to drive profitable growth. With that, I will now open the call to any questions you may have.

It seems like you're making good progress around improved metal sourcing and the flow path at work. But can you provide a little bit more detail about the timing on when you see that optimized? And what level of margin or a cost-down impact you could see from those efforts? And then, I guess with respect to metal we've seen a pretty material increase in the LME aluminum price this past month and then there's been more discussions around potential trade tariff impacts, so I was wondering if you could provide any more color on how you could see that impacting your business going forward?

Okay. Well, thank you, Curt, and I'll take your first question first. Yes, we are continuing to make solid progress there. The first couple of years were a little troublesome with supply chain issues and whatnot. But as I mentioned in my comments, we're finally getting to some more normalized output here and operations. So the strategy change has really been picking up. We planned on looking at different metal sourcing that had been planned from day one and we just began initiating that in Q1. I expect that will continue to pick up through the balance of the year. The big strategy changes we've discussed earlier have been when we're moving toward higher-margin coated products, which is really facilitated by this investment we're making at Warrick. And while we're making great progress there, that strategy isn't really initiated until the beginning of 2025. As we said in some earlier comments at the beginning of the year, we expect a 300 basis points to 400 basis points impact once we fully implement that strategy at Warrick. So we've got a good runway ahead of us, but I'm pleased that on the normalized side, we're getting a hold of the operation and folks are beginning to operate very well. Quite frankly, the quarter could have been even better for us, but we had taken down some major pieces of equipment for planned maintenance and work. And so we weren't able to take even more of the demand that was coming at us. So all in all, I'm very pleased with the progress we're making there. And I believe that that's going to continue to improve as we go out through the year, especially as we see demand improving in that area. Now moving to your second part of your question, Curt, on the trade tariff, we've prided ourselves in this company of being on a pass-through basis with regards to metal. We've got long-term, very diverse supply arrangements in place with metal providers. At the beginning, we haven't utilized any Russian material since the beginning of the Ukrainian war. Even at that time it was a small amount. I know the impact on the LME is larger because there was a good deal of that material available there. But quite frankly, with the internal work that we're focusing on with a higher use of recycled material, using more secondary metal as opposed to the prime, and with our business pass-through strategy, I really don't see a big impact to us with regards to tariffs on the metal itself. Now, we are susceptible to some of the products that come through imports, and we'll be very focused on work and stuff that the administration is discussing with regards to some controls on inputs of unfair advantage material in the products that we provide. So we support those and will continue to monitor the landscape and adjust accordingly. But I like how our business philosophy allows us to adapt to all these changes.

Okay. And then as a follow-up, the aero high-strength market it seems like you're tempering your expectations modestly on a volume basis on the past when we've seen some slowdown in the aero supply chain, things again can get whipsawed pretty heavily on the inventory side. Can you just give us your view on how you think the aero supply chain is looking for sheet and plate? And then in terms of the more conservative outlook, I know Boeing is a pretty big customer and they've tempered their expectations a little bit on the 737 MAX. But can you just talk through how you see that supply chain evolving maybe into the second quarter and the back half of the year?

Sure. I think your comment is something that we watch very closely with regard to inventories. I don't hear it mentioned very often, but we follow those quite intently. I believe for mainly a lot of the challenges that the big OEMs have discussed with supply chain issues, whether it was related to current issues that Boeing may be facing or even Airbus from a supply chain perspective, we had a little muted demand as expected compared to what we expected on the build rates. And so that was the reason for a slight pause on our side. As you pointed out, Curtis, it's about a 1% to 2% change in what we said 2 or 3 months ago. I think there's a little caution in there. The good part here that I always refer back to is that over the last 15 or 20 years, none of this has been linear. We've always seen some pauses and operations either by certain platforms or by conditions that take place, geopolitical or whatever. But I believe these issues are going to be short-lived. I was recently at a supplier meeting with Boeing and they're really putting emphasis on getting their supply chain and their operations in sync. I believe they're going to achieve that fairly judiciously. They've made strong commitments to not only their customers but also to their suppliers. And I have a lot of confidence in that as well. We know what the inventory levels are. We know what the little bit of the pause has been with the uncertainty of when the ramp rate goes back on the MAX, for instance. That's a little bit the reason for our caution. But I believe all that's going to be handled quickly, and we're still in a very strong position. It’s really going to depend on how fast they ramp back up on the sales as to whether or not we'll see any further impact on the outlook. But for now, again, it's the reason we've always emphasized our diversity in this field, focusing on defense, business jets, and other outlets for our products, including space, which is growing. I think that helps minimize anything that's been going on lately a lot more than perhaps it did for us 4 or 5 years ago.

If we think of those buckets within aerospace you just mentioned your large commercial, business jet, defense, and space. How have those different buckets folded in the guide for the year?

Yes. So, how we've looked at those various components, you can imagine they move a little bit. But we said that the commercial large commercial jets had been between 50% and 60% of the total demand outlook for aerospace for us, and then the other buckets move around in that remaining 40% to 50%. For instance, defense has been growing a little bit. Business jets have been strong, but now we're starting to see space drive a stronger modifier to those numbers. So when we’re talking commercial aerospace, the large commercial aerospace that’s a sizable portion of our business. And so, obviously, we monitor all these components very well, including the stocking and destocking that take place. And so I would say that right now on the non-commercial aerospace, we’re in a very good position from a stocking and inventory perspective, and demand is still holding up very strong. So we’ve got good confidence in that for the balance of the year. I think what you saw, Josh, in our comments there is that short-term, we like for Boeing on this 90-day quality assessment with the FDA. They’re about halfway through that, and I don’t foresee them really going back to launching the build rates of where they’re focused on right now 38 until after that period is over. So I think that could probably have a continued impact on perhaps more of the second quarter. But then I believe Boeing is absolutely committed to making the changes required and adjustments, and I think they're going to be more focused and back toward those expected build rates toward the second half of the year.

And then just as far as heading into this week's announcement with Boeing, were the service centers and distributors already hearing and their body language and their ordering cadence? When did that kind of turn? Or did it turn ahead of the announcement?

No, I would say it really hasn’t turned so much in that. I give great credit to this. Boeing has reached out to their top suppliers and really had a good conversation about what they intend to do. They can't tell exactly because they’re working with other principals to try to put things in place, but they’ve been very focused on ensuring that the supply base and everything has been transparent. Good communication, good open discussion about where inventory levels are due to build rates and then and then expectations going forward. What I really appreciate is the openness of having a dialogue instead of just actions resulting in us just reacting to their actions. So I believe there's strong management of this process, and I believe any impact that we feel at all should be minimal.

Nice job in the first quarter margins and the reiteration for the full year. But I guess if we were just a flat line you'd actually come in even above that expectation. So I'd like to understand that trajectory from here. Maybe what was sort of one-time in nature in the first quarter that maybe doesn't repeat in the second quarter of any sort of color on how to think about the margin progression for the balance of the year would be helpful.

Certainly. Well, a few things happened in the first quarter build that were a pleasant surprise to us. One, we had talked about the concern about compression in pricing as we had gone into the year. We really did not experience that in the first quarter. Now I'm not taking that away. I still believe with North America being one of the strongest markets out there, we tend to attract a lot of other players and other countries that aren't doing so well. So there's always that outlook with a little concern about some price compression. And so we work that into the outlook going forward. The teams did a great job from a cost control perspective, so the big outlook for us is on that normalizing of operations. We’re really starting to get back into the tone of how we like to operate our businesses, which is managing cost, strong efficiencies, and good improvements across the board. I think that's something that will continue on itself. The final thing that we took into account was that we had very strong aerospace for the quarter, especially as you compare it to the first quarter of last year. As we've stated, we've now got 4 or 5 quarters of good, strong improvement on the aerospace and high strength. For the balance of the year, just what we finished talking about with the large commercial production and perhaps some pauses — I would call it a general pause or something which just gives us a little caution as we go through the balance of the year. But what I'm really focused on is that we're acting toward the plan where we expected to be. Perhaps we got out ahead a little bit on the first quarter, which is good news, and we'll see how the balance of the year goes. But it's always better to be off to a great start and have some deployed tactics and strategies in place that you know are moving you to your ultimate goal.

Okay. Yes, thanks for those insights. On the general engineering, it's nice to see the improvement in the business that you're expecting. I guess I'm trying to understand what you're seeing in the segment that gives you confidence. Is there anything to call out: general industrial improvement, semiconductors? Perhaps you could speak to the visibility you have considering, especially 90 days ago, you were more confident about aero and now you're less. So just any visibility would be helpful on this segment.

Yes. And I'll preface the comment on aero, Bill. We've just moved down from the up 1% to 2% to just flat year-over-year. I'll remind everyone last year was the best year we've had since 2019 and even exceeded 2019. So it's at a pretty good level. But then back to your point about general engineering, we've talked about it for years that we track inventory levels at our service centers and certain products, and we've got canaries in the coal mine that help us understand where we are in certain phases of the markets. I can tell you, we've been tracking. We've gone through about 14 months of destocking one of our key product lines, which has been our rod and bar products in the extrusion side of business. For the first time in March, we actually saw inventories begin to rise again. That really supports my comment about us believing destocking has ended, and while we’re at a lower pace than perhaps we were a year and a half ago, supply and demand seem to be in sync at this point, and we saw some fairly solid numbers for the first quarter. So I believe that bodes well going forward for the balance of the year, typically that has always done that. The same comments I made on packaging. We have been talking about destocking on the food pack side of our business, which was pretty important. We had been through about 12 months on the beverage side, and it was anticipated that we would be ending the destocking in the first quarter on those products. Indeed we did see that destocking come to an end, and we could have sold more during that period. We have not had the outages that I discussed earlier. So those two big markets show that destocking has ended. We are seeing a rebound that gives us really good confidence for the balance of the year. You mentioned one other market that we traditionally comment on and that’s the semiconductor market; while we wouldn’t say that we’ve seen that demand tremendously improve, we are seeing green shoots of improvement. That’s helpful for us, especially as we have to reconcile our general engineering with our aerospace and our sheet and plate business. So, I think that's going to improve as we go forward. But certainly, we've seen it on the rod and bar segment. That’s some of the data behind our outlook for general engineering.

Okay. That's helpful. If I can sneak in one more, CapEx is a little bit light in the first quarter. I guess how should we think about the trajectory here in the second quarter and the back half of the year?

Hey, Bill. It's Neal. Yes, definitely the first quarter was lighter than anticipated. We thought the quarters would be a little bit more equally spread, but we now see that the second quarter will really be the highest spend of the year for CapEx, with the last two quarters of the year kind of back to normalizing probably equal to the way the first quarter was. So, really look at the second quarter as where we're going to have the big spend as we get that roll coat line to contractors and all that paid as they start delivering and completing their work.

All right. Thanks, Maria, and thanks everyone for being with us today. I look forward to updating you on our second quarter 2024 results, when we meet again in July. Have a good day.

This concludes today's teleconference. You may disconnect your lines at this time. Thank you for your participation.
