Thank you for standing by, and welcome to the Q4 and Full Year 2023 Armstrong World Industries Earnings Conference Call. I would now like to welcome Theresa Womble, VP of Investor Relations and Corporate Communications to begin the call. Theresa, over to you.

Thank you, and good morning to everyone on our call. On today's call, Vic Grizzle, our CEO and Chris Calzaretta, our CFO, will discuss Armstrong World Industries' fourth quarter and full year 2023 results and 2024 outlook. To accompany these remarks, we have provided a presentation that is available on the Investors section of the Armstrong World Industries website. Our discussion of operating and financial performance will include non-GAAP financial measures within the meaning of SEC Regulation G. A reconciliation of these measures with the most directly comparable GAAP measures is included in the earnings press release and in the appendix of the presentation issued this morning. Both are available on the Investors section of the website. During this call, we will be making forward-looking statements that represent the view we have of our financial and operating performance as of today's date, February 20, 2024. These statements involve risks and uncertainties that may differ materially from those expected or implied. We provide a detailed discussion of the risks and uncertainties in our SEC filings, which include the 10-K filed earlier this morning. We undertake no obligation to update any forward-looking statement beyond what is required by applicable securities law. I will now turn the call to, Vic.

Thank you, Theresa, and welcome everyone to our call today. I'm delighted to have this opportunity to discuss our 2023 results and our expectations for 2024. For those of you who've been following us for a while, I'm sure you'll appreciate the sentiment of what a difference a year makes. We began 2023 with a rather cautious view as many did, with expectations of a negative market backdrop with high-levels of uncertainty, and in particular in the back half of the year. We're also coming off of 2022 results that were pressured by several factors like rapidly rising inflation, higher interest rates and overall economic uncertainty. Despite these factors and with softer office demand, the economy in our markets overall fared better-than-expected in 2023. Better-than-expected markets along with our team's consistent and steady execution helped deliver our strong results for both the quarter the year. On a total company basis for the full-year, we delivered record setting net sales of $1.3 billion which was a 5% increase from full-year 2022 results. Our adjusted EBITDA grew 12% to $430 million representing 200 basis points of improvement in our adjusted EBITDA margin. This result was also 7% greater than our prior record for adjusted EBITDA of $403 million set back in 2019. On an adjusted diluted EPS basis, we delivered growth of 12% and our adjusted free cash flow of $263 million grew 19% above prior year results. We are pleased with these strong results as they represent an ongoing demonstration of Armstrong's resilient business model with its strong market position, a diverse and balanced set of end-market verticals and attractive growth initiatives. These attributes allow the Company to deliver revenue and earnings growth with margin expansion even in soft market conditions. These results also reflect the work of more than 3,000…

Thanks, Vic, and good morning to everyone on the call. As a reminder, throughout my remarks, I'll be referring to the slides available on our website and Slide 3, which details our basis of presentation. On Slide 6, we discuss our fourth quarter Mineral Fiber segment results. Mineral Fiber sales grew 2% in the quarter, primarily driven by AUV, which represents a combination of like-for-like pricing and mix. In the quarter, AUV growth was driven by favorable like-for-like pricing, partially offset by unfavorable mix. We continue to deliver strong price realization in-line with expectations, but mix was a headwind, largely due to mix dynamics within our channels, which we believe are timing-related. AUV remains a core value driver for the Mineral Fiber segment and despite mix pressure in 2023 we delivered full-year AUV growth of 5% which is in-line with our historical average. Mineral Fiber volumes were essentially flat in the quarter as contributions from our growth initiatives offset a softer market. While Mineral Fiber volumes were flat compared to the prior year, they were ahead of our guidance expectations as the market in the fourth quarter was broadly more resilient than we expected. Additionally, sales volumes to retail customers were also better-than-expected. While retail sales provided upside to our volume expectations, it also contributed to an AUV headwind in the form of channel mix versus our outlook. Mineral Fiber segment adjusted EBITDA grew by $3 million or 3% and adjusted EBITDA margin expanded by 50 basis points in the fourth quarter. The fall through of AUV and the contributions from WAVE equity earnings were the primary drivers for margin expansion versus the prior year period. As expected, manufacturing costs were higher than prior year due to the lapping of a strong prior year period where we saw both outsized…

Thanks, Chris. And before we get to your questions, I'd like to take a moment to share a few highlights from Armstrong's proven ability to consistently and steadily invest back in our business and innovation through all parts of the cycle. In January, we announced a new partnership with McKinstry, an innovative leading construction and energy services company, to tackle another challenging aspect of construction today, the waste and inefficiency in the installation of systems, devices, and components needed to meet today's tenant requirements. With an equity investment in Overcast Innovations, an early stage McKinstry venture, we're co-developing plug-and-play systems that streamline this increasingly complex process. This represents an integrated approach that goes well beyond ceiling tiles. Overcast works with architects to integrate HVAC, lighting, audiovisual components, sensors, and other ceiling equipment into factory manufactured architectural ceiling solutions. The partnership and investment are expected to accelerate Overcast growth through access to Armstrong's portfolio of ceiling solutions and go-to-market platform. By bringing together industry leading Armstrong ceiling systems with Overcast pioneering integrated modular ceiling design, we can offer unique and sustainable solutions. Another area of focus has been innovation in our Healthy Spaces initiative and has evolved over time to include the energy efficiency and overall thermal comfort of commercial buildings. As you may know, buildings are responsible for nearly 40% of global energy consumption and in the U.S. alone, this energy consumption represents nearly 75% of all electricity used and 35% of the nation's carbon emissions. Importantly, over 50% of that energy consumption is used to heat and cool buildings. As part of our research and development efforts, we have focused on how ceilings can play a significant role in creating healthier and more sustainable spaces and enable energy efficiency for more sustainable buildings, and ultimately accelerate the efforts of…

The floor is now open for your questions. [Operator Instructions] Our first question comes from the line of Garik Shmois with Loop Capital Markets. Please go ahead.

Hi, thanks and congrats on the quarter. I'm hoping you could speak a little bit as to what you're seeing so far, in the first quarter, we've been hearing from other companies, that weather had been a little bit of a headwind, not sure if that's impacting you and then maybe speak to, how you expect, the slope of the year to progress both for sales and margins, anything to take in account there?

Yes. Garik, on the direct part of your question, we've not seen any measurable impact on weather on the business in the first six weeks of the year here so far. So, let me answer that directly. What we're seeing in the marketplace and what we expect to see to start back with the third quarter of last year, we saw a market that again was better than what we were expecting. And then in the fourth quarter, we saw a very similar market condition than that we saw in the third quarter. So, as we outlook the halves of the year in 2024, we kind of expect that the first and second quarter, the first half of this year to be fairly similar to what we saw in the back half. It seems to be just kind of at this level, just progressing along at this level. In the back half is where we have more uncertainty again with the lag effect of our business and the lag effect of higher interest rates, overall slower economic activity that's expected. We see that that could potentially hit the discretionary part of our business and we might see some softer market conditions and softer volumes in the back half of the year. That's our current outlook. Again, there's some uncertainty with regards to exactly what we're going to see. And as Chris mentioned in his prepared remarks, we don't see the same kind of, variation in the potential outcomes as we did going into ‘23, but still there's some uncertainty about what is the overall economic activity going to look like. So, kind of, a first half as we've been seeing, recently in recent quarters, maybe a little bit modestly softer conditions in the back half.

No. Thanks for that. I wanted to follow-up on capital allocation, just given your strong free cash flow position, balance sheet is in good shape, just thoughts on priorities and maybe speak to the M&A environment as well?

Yes. Hey, Garik. It's Chris. I'll take that. And then, Vic, you wanted to add on a little bit on the M&A side. Yes. I mean, our approach to capital allocation priorities remain unchanged. I mean, we invest back into the business first, where we see a lot of our highest returns. And then, second, seek to grow, by way of inorganic growth to create shareholder value. And returning cash to shareholders continues to be our last priority, our third priority. And, we continue to flex with share repurchases. And as you've gone through, our strategic planning and long-term planning for the business, we believe that there's value creation there and following those disciplined capital allocation priority steps, they remain unchanged and, believe that they're the best way to continue to deploy capital for the Company.

And to point Chris' point, our second priority is the use of free cash flow to bolt-on acquisitions that add capabilities to the Armstrong platform, to accelerate where we're trying to go and especially in this fragmented specialties category. We still believe there's lots of opportunity there. We continue to pursue those opportunities. I would say we're very active. Our pipeline is very active and fluid. I think a lot of the questions that we get are around how interest rates and so forth may be affecting our pipeline. Again, a lot of these companies that we're working with or trying to get closer to are not in a sale process and so are not affected really by interest rates or the interest rate environment. So, we continue to build these relationships with targeted companies that we think would add a lot of value by being on the Armstrong platform, and we'll continue to build those third-party relationships with those that we think we don't need to own the assets and we can use our capital elsewhere. So we remain active. We still believe that there's a good set of opportunities for us to go faster in the Specialty segment through these acquisitions, and we'll continue to build that pipeline and hopefully get some of those across the finish line.

Makes sense. Thanks again. I'll pass it on.

Yes. Thank you.

Thank you.

Our next question comes from the line of Philip Ng with Jefferies. Please go ahead.

Hey, guys. Strong finish to the year, so congrats to the team. So Vic, it's good to hear that demand is off to a pretty solid start in the first half. Any color on how orders and bidding activity have trended lately, particularly in some of the more challenged end-markets like office and retail? Are you starting to see those activity, or bottom out here? And you commented about how the back half could be a little more weaker? Is that informed by your customers or you're just kind of baking in some conservatism?

Yes. So first of all, Philip on the bidding activity, fourth quarter bidding activity was positive. And it was kind of choppy all throughout the last year as we reported in 2023. I would say overall bidding activity for the year was stable, with the Q4 again being positive. Interesting enough, as much as office gets talked about, I think it's worth noting that the office bidding activity was positive in 2023 in both the number of projects and the value of projects. We think this is another signal of this sector in particular stabilizing along with some of the other things that we talked about in our third quarter with leasing volumes, increasing 14% in the quarter. The supply at the high-end continues to get tighter both in the Class A and A plus part of the marketplace back to office mandates of 90% of the Fortune 100 employees are now back in the office an average of three days a week. So, there's lots of signs that are pointing to, a stable office market in particular. And then that's again complemented by some additional strength that we're seeing in education, and the retail in particular. So again, I would say overall, Phil, the market that we're experiencing in the back half of last year is what we're seeing so far. And again, it's very early in the year, but that's what we expect to see in the first half of this year. In the back half and to the second part of your question, so I think this is both informed by our customers who have less visibility in their backlogs into the back half of the year. Although it's a different than it was at the beginning of 2023 where there was a lot more concern about the back half of the year. There's still, it's still informed by our customers who have less comfort I think in their backlogs for the back half of the year. And again that's where some of the indicators lagged would say that's where some of the weakness could show up. Again, a lot of this is probably more on the discretionary side. So, we'll have to get closer to the back half to see exactly, what happens on the discretionary side of this, which again, we have a lot less visibility on some of that smaller discretionary project work.

Okay. That's incredible color, Vic. And then for your AS business, you're guiding to call it 6% to 9% growth in 2024. I believe roughly about two points of the M&A, but nonetheless that's pretty strong growth. So, I'm just curious where you're seeing some of the strength from end-market standpoint. You certainly called out infrastructure and transportation being a big part of that. Any way to kind of help us parse out how big is that piece of the business for AS?

What I would point to Phil is the, on the new construction side, if you recall in the back half of 2022, we had pretty good new construction positive, new construction starts. We should benefit from that, in 2024 continue to benefit from the lag of those new construction projects coming through. I think in the larger alteration projects, office and education again were positive and I believe we're going to continue to see some, some of that benefit, in both office and education. And you mentioned transportation. It's a relatively small from a square footage standpoint segment, but it has big dollar opportunities when it comes to the Architectural Specialty segment. We remain very busy with our bidding activity there. We expect transportation to be a meaningful contributor to the overall Architectural Specialty segment growth in 2024 and as I outlook, I think beyond.

Okay. Thank you, guys. Really appreciate it.

You bet. Thank you.

Our next question comes from the line of John Lovallo with UBS. Please go ahead.

Good morning, guys. Thank you for taking my questions as well. The first one is just on the comps in the first half, in Mineral Fiber in particular. I mean, they're a little bit tricky with, I think, a plus nine in the first quarter. I think on a volume load and then a minus seven, in the second quarter. How should we sort of think about those as we move into the first half of this year? And then along the same along similar lines, input cost inflation, there's a lot of moving pieces with energy and other items. How are you kind of thinking about that through the year?

Hey, John, it's Chris. Thanks for the question. Yes, on the volumes, Mineral Fiber, so looking at first half, second half, splits, we're guiding to Mineral Fiber volume being down in that low-single-digit range with a little more softness in the back half than the front half. And that really mirrors the, remarks that Vic made about the overall market. And, you're right. First quarter, we're lapping a really strong comp of the first quarter of ‘23 where we saw some of that inventory build in retail. So, a little bit of softness in Q1 and then, kind of just the opposite in Q2, to the comp that you point pointed out. But I'd overall, say back half a little bit softer on the volume side than the first part of the year. On input costs, you're right. We're basically out looking for full-year total input cost inflation to be inflationary in the low-single-digit ranges range on a percentage basis and kind of break that out a little bit. Raw materials, we expect those to be inflationary low-single-digits, freight to be slightly inflationary. And then, deflation in the area of energy driven primarily by nat gas. So again, total input costs inflationary in that low-single-digit range for ‘24.

That's really helpful. Okay. And then maybe just taking a step back here, the Investor Day targets you guys outlined 2% to 4% Mineral Fiber growth. I mean, 2024, the expectation is for it to be down low-single-digits. As we progress through this year, how should we sort of think about the drivers of the improvement in Mineral Fiber volume and maybe as you see the cadence over the next couple of years, if possible?

Yes. John, let me take that. I think that, when we think about those, of course, the world kind of changed in 2022 right after that Investor Day, conference. But, when you look back at the building blocks of that guidance and we sit here today and look at those building blocks, they haven't changed. They really are the same building blocks. I think we've got to get to the stabilization of the market. We did outlook, one of the building blocks is a recovering commercial construction market. And so, as we get on the other side of ‘24 and move into a more positive backdrop for commercial construction with lower interest rates and so forth, I think then we start to see the materialization of one of the main building blocks there, which is the overall recovery of the commercial construction marketplace. Again and then our growth initiatives on top of that, and then acquisitions coming along the way, we think the building blocks are still there for, positive Mineral Fiber bond growth, which is your specific question, but the other building blocks for overall profitable growth for the Company.

Got it. Thank you, guys.

Okay. Thank you.

Thanks, John.

Our next question comes from the line of Susan Maklari with Goldman Sachs. Please go ahead.

Thank you. Good morning, everyone, and congrats on a good quarter.

Thank you, Susan.

Thanks, Susan.

My first question is thinking about your guide for Mineral Fiber volumes to be down low-single-digits. Can you give us some sense of how much of that is driven by the underlying market and the conditions that you've talked to relative to some of those organic initiatives and the benefits that are starting to come through from those?

I’ll take it.

Okay.

Susan, yes, the volume I think the way to think about the volume build on this is we have an overall, I think softer, level of economic activity that is going to impact the overall business. And I can, across all of the verticals will be subject to lower levels of activity. So, that's kind of the backdrop. We're going to partially offset some of that with our growth initiatives, like we did in ‘23. We feel really good about the progress and the traction we're getting there. The other thing that is going to come out is some of this retail inventory build that we talked about all through 2023 and we were expecting some of that to come out in ‘24 didn't come out. And so, we're factoring that also in, coming out in 2024. So, you've got a couple of puts and takes there. It's not all market softness. Again, we're out looking a modestly softer overall economic backdrop and again partially offset with our growth initiatives and then a little bit of headwind from some of this inventory coming back out of the system in ‘24. Does that help?

Yes. That is helpful. I mean, we're trying to understand, it sounds like a lot of your organic initiatives have been gaining some nice momentum over the last couple of quarters, and just how does they go about the continued benefit of that over the coming quarters and where that can go relative to a softer market?

Yes. We expect that to continue, that traction there to continue in ‘24, for sure.

Yes. Okay. That's helpful. And then, turning to the Architectural Specialties margins, you're obviously continuing to make some really nice progress there getting close to that 20%. As you think about this setup for this year, how are you thinking about the ability to actually get to that 20% or really within striking distance of it? And what are maybe some of the puts and takes that could come through in terms of the margin in that segment?

Yes. We're really within striking distance, right. I mean the path that we're on is very encouraging in terms of getting the operating leverage that we needed to see from the capital investments we're making in the business as well as some of the SG&A that we were investing ahead of growth a couple of years back. So, we're on the, I'd say, good path there to get the operating leverage there. And then our pricing initiatives too, we're doing a good job and making sure that we're pricing projects the right way. We're getting some of the acquisitions on our pricing platform. So, those things that we're doing and we've demonstrated for two years in a row now that's what we have to continue to do in 2024. And, we won't make any short-term bad decisions, to artificially get there. I think that's the discipline that we're using. Some of these large airport projects that we talk about, one of the things that we did in ‘23 is, and late ‘22 is, we invested in some additional resources to create multifunctional teams to go after some of these larger complex projects. And that's an important flex that we were able to take so that we could better position ourselves for winning some of these large airport projects. If we see opportunities to do that, we're going to continue to do the right thing in the short-term for our business over the long-term. But we're in striking distance and we're pushing to get there. I really like the path that we're on.

And Susan, maybe just to call out too and build on that a little bit is, in the appendix, we have the adjusted EBITDA margin assumptions for both Mineral Fiber and AS, and we're out looking about 19% EBITDA margin for AS and about 40% for Mineral Fiber.

Okay. That's helpful. Thank you both for the color, and good luck with everything.

Thank you.

Thank you.

Our next question comes from the line of Keith Hughes with Truist. Please go ahead. Your line is open. Please go ahead.

Thanks. On the guide for Architectural Specialties, what's the revenue guide, what's the breakout between organic and acquisition?

Yes. Really, I'd say within the, AS segment, we're guiding, 6% to 9% on the topline with, I'd say, really minor contribution from inorganic on that. It's really the market and continued market penetration that's driving our growth and expected growth in ‘24.

Okay. And one other question. You talked about there was an inventory adjustment amount in the fourth quarter. How much was that? What segment did that show up in?

You're referring to inventory valves?

Yes.

Yes. It was small. It was small. If you remember back in 2023, we had in the first quarter a pretty sizable valve impact. And in the fourth quarter, it was a much smaller amount. About half of the input cost line on the bridge was valve related in Q4.

Okay. Great. Thank you.

You're welcome.

Thanks, Keith.

Our next question comes from the line of Rafe Jadrosich with Bank of America. Please go ahead.

Hi, good morning. It's Rafe. Thanks for taking my question. First, I just want to add on the Mineral Fiber revenue guidance. What are you assuming for share gains, your performance relative to the market in ‘24? And then it sounds like there was a mix headwind in ‘23 and, Vic, you just mentioned to an earlier question that there's some expectation of retail destocking in ‘24. Do you expect the mix sort of headwinds to reverse in ‘24? Is there anything that's changed in your overall mix going forward?

Yes. No, I think mix is going to be a positive contributor in ‘24 for a lot of the same reasons why it was a headwind in ‘23, which is this channel imbalance between the retail channel and some of our higher AUV channels. So, yes, I think we expect some of that inventory to come out of the retail channel, which again brings it more back into the balance of our higher AV, which allows then the product mix, which is ultimately the driver of our mix as a Company is the product mix is able to shine through and contribute when the channels are better in balance. And hopefully that makes sense. But that's one of the drivers of this business is 70% of our business is renovation work. And when architects and designers and building owners renovate, they don't put the old stuff back in, they put new stuff back in. So, it naturally wants to mix up to higher value, higher performing products that's happened for over a decade and we would expect that to happen for the next decade that this natural industry dynamic is going to continue. And, that's what will begin to shine through in ‘24 again once these channels come back into their proportional balance.

And then just on the share gain assumption for 2024?

Yes, we're not assuming any share gain in our assumption. Again, we're driving category expansion with our initiatives, and we're getting our proportional share of that expansion. So, the growth dynamics for us really around what the market is doing offset by our positive contribution from growth initiatives.

And then just on the Mineral Fiber, margin assumptions, can you just because natural gas prices have moved so much or come down so much, can you talk about the assumptions embedded in your guidance? What is sort of the tailwind from energy in ‘24? And then, can you talk about the strategy around hedging going forward? Like what's rolling off there, and where are you resetting?

Chris, you want to take that?

Yes, so sure. Remember about 30% of our Mineral Fiber inputs are tied to raw materials, 10% freight, 10% energy. So, as I shared earlier, raw materials, we're expecting inflation in the low-single-digit range. Freight, again, to be slightly inflationary low-single-digits. And, then really a tailwind on deflation largely driven by nat gas. And as we model that, we look at a bunch of, different inputs to that. Obviously the NYMEX forward curve, kind of shapes and influences that. But again, looking back at recent history with nat gas, it's really hard to call and hard to peg. But we do have nat gas as a deflationary item, in ‘24 and that's really driving that inventory that energy category. I'd say from a hedge position perspective, we have a little bit carried over into 2024 really immaterial when I think about it and to a much lesser extent, than we had, in terms of price locks in ‘23. Kind of that said going forward, don't expect as much of a volatile nat gas environment as we saw, in ‘22 and ‘23. So, not looking to really hedge or do any price locking longer term.

Good. Thank you. Very helpful.

You're welcome.

Our next question comes from the line of Stephen Kim with Evercore ISI. Please go ahead.

Yes, thanks very much guys. Appreciate all the color so far. Wanted to just talk a little bit about the inventory drawdown at the home centers, it's been discussed a bit already, but it looks like you didn't see it show up last year. You're expecting it again in 2024. I was just wondering if you could give us a sense for why it didn't show up as you expected over the last couple of quarters, and are you expecting this to materialize in the first quarter or some other time later in 2024 in your planning?

No, I think this is really hard as you know Stephen, for us to control or let alone and predict it for sure, let alone control it. But what we expect is we've just kind of sprinkled this in throughout the year that they'll come to some, normalization around their inventories. Why these home centers is a good question. It's a different answer for different home centers, but there's timing in which they are re-merchandising, their shelves, around ceilings, for example. So, that can drive a different behavior around inventory build across their stores. And again, we see that, on the other side too, when they draw them down in anticipation of a merchandising change. So, it's kind of in-line with what we see periodically with these, these home centers. Sometimes they're out of phase with one another and it's a little quieter and sometimes they're in phase with one another and we feel it and we have to talk about it a little bit more. But, it's really timing related and they do come to some normalization, over time in their inventory channels, with our good service and they're able to do that. So, again, we're not loading it into the first quarter. We don't expect that. We expect that probably to just normalize over the transition from quarter-to-quarter throughout the year.

Okay. That's helpful. Appreciate that. And then Vic, you earlier talked about your investment in multifunctional teams that are required to really go after the more complex, longer, larger project in a better way and you've attributed the success of that or those investments and the subsequent success to some of the great things that we've been seeing in Arch Spec. But you then I think to Rafe's question, you said that you did not think that you sort of gained share. You're not like gaining share. And I just wanted to make sure that I'm understanding was that a remark around Mineral Fiber, just because maybe you can help us understand if you didn't take share, these sales of products that went that go into these more complex projects, they obviously previously were coming from somewhere, right? How have these multifunctional teams that you put together actually changed the way those projects are serviced, which has a near to your benefit. If you could just help us understand that a little bit better?

Yes, Stephen to be clear, Rafe's question was around Mineral Fiber assumption around share gain and our Mineral Fiber build. So just to be clear, my answer to Rafe's question was around we're not baking any share gain in our Mineral Fiber volume assumptions, like we never do. That's not how we build our Mineral Fiber volume plan. So, just to be clear that my answer was around Mineral Fiber volume. To your point, it's very different in Architectural Specialties. We are penetrating this segment. We are taking share in this segment. We have been for a number of years now. At these multifunctional teams are just allowing us to leverage the entire portfolio that Armstrong brings to these projects. There is no other company in the ceilings category that can offer the breadth of portfolio. And now with our ProjectWorks design platform, there's lots of things that we can bring and it really requires a multi-functional team to bring all of those attributes to bear on these large complex projects. So, it's part of our competitive advantage that we're creating, but it's also the point of leverage for the unique attributes that Armstrong can bring to these large projects. So, we're really, we're pleased with the traction these teams are getting and the effect it's having on our win rates in airport projects, large projects overall.

Yes, that's encouraging. Appreciate it. Thanks very much.

You bet. Thank you.

Thank you.

Our next question comes from the line of Kathryn Thompson with Thompson Research Group. Please go ahead.

Hi. Thank you for taking my questions today. Just a clarification on volumes. You gave some color on quoting activity, but could you do the same in terms of cancellations? Are you seeing any change in an uptick or stasis as you've seen from the previous quarter?

Yes, Kathryn, I think on the volume side in Mineral Fiber, we've been watching the cancellations and these projects have been delayed or put on hold, but we've not seen a lot of cancellations and I would say that has continued throughout 2023. And in fact, in Q4, when we look at, we thought the market would soften a bit in Q4. What we really saw was some of these projects that were on hold or in that discretionary bucket, filled in some of the gaps in Q4 that kept the market kind of at a very stable level from Q3 to Q4. So, I think to that point of not a lot of canceled projects keeps them in the wings when they're on hold so that they can be pulled forward or pulled into the system, as there's capacity and a willingness to do so.

And also just a clarification, did Q4 see any benefit from the timing impact from big box? Now that had been a factor in for certain quarters early in 2024?

Well, there was a little strength in the retail channel that drove some of that mix that we talked about earlier. Again, that relative strength is relative to the other channels. So, I wouldn't say, I wouldn't put a lot of activity in the channel, but relatively it was stronger than some of the other higher AV channels that drove that mix. So, not a lot of additional inventory build if you will in the quarter for us to point to say that was a big driver of the overall improvement.

Okay. And then finally on WAVE, could you outline some of the factors driving your projections for 2024 with WAVE? And how much of that is driven by core market growth versus just other fundamental changes or growth initiatives in WAVE? Thank you very much.

Yes. Kathryn, I think the way to think about the WAVE business and the way we're modeling the WAVE business is very similar to the overall market conditions that our Mineral Fiber business sees, right. We do sell grid and ceiling tiles as a package through our distribution. So, the overall market backdrop and market assumption is virtually the same for our grid business. So, I think you can factor the volume side of that. What could be a little bit different in that business is the pricing ahead of steel inflation, it’s something that our team does really well to watch what's happening with steel commodities. And, so that can move their sales and of course their margins, based on how well they do. And they have a really strong track record of doing a great job of staying ahead of steel inflation to protect their margins. That's kind of how we've modeled it going forward is that they're going to continue to stay ahead of inflation with their price initiatives and the volumes they'll experience are very similar to what we're expecting on the Mineral Fiber volume side. Okay?

Thank you very much.

You bet. Thank you.

Our final question comes from the line of Adam Baumgarten with Zelman. Please go ahead.

Hey, good morning. Just a question on Mineral Fiber volumes. If we look at the back half of ‘23, how do you think your volumes perform versus the broader market? And then also were there any notable market share shifts within any channels last year?

Well, I think our growth initiatives really contributed in the back half as we talked about, Adam. I think, the market was down low-single-digits, which was better than what we less worse, if you will, than we expected, right, in the back half. And, I think we certainly offset a good portion of that market softness with our growth initiatives. And so, I think that's what we expect to continue going into 2024.

Okay, got it. And then just on the AUV guidance, does that assume the typical two price increases throughout the year in Mineral Fiber?

Yes. We're getting back to our normal cadence of twice a year price increases. And again, remember AUV is both price, like-for-like pricing that comes from these two price increases you're referencing, but also the mix component of that, so which we talked about earlier on the call that we expect mix to be a positive contributor to AUV this year.

Okay, got it. Thanks. Best of luck.

You bet. Thank you.

I would now like to turn the call over to Vic Grizzle, for closing remarks.

Thank you, and thank you all for joining and thank you for your questions today. We're very proud of the team's results this quarter obviously, and we look forward to updating you again in April on our progress. Thank you and have a nice day.

This concludes today's call. You may now disconnect.
