Reconciliations from GAAP measures to non-GAAP measures are provided in the appendix at the end of this presentation and on our website. A friendly reminder that some of our comments and answers during this conference call will be forward-looking statements that are subject to risks that could cause actual results to be materially different. Those risks include matters that we described in this morning's press release, among others. Also, as a courtesy to others in the question queue, please limit yourself to one question and one follow-up for churn. If you have multiple questions, please rejoin the queue. We will be using slides as we move through today's call. You can access them on our website at investor.aosmith.com. I will now turn the call over to Kevin to begin our prepared remarks. Please turn to the next slide.

Thank you, Helen, and good morning, everyone. I'm on Slide 4 and our full year results. 2023 was a record-setting sales and earnings year driven by resilient water heater demand and excellent execution by our team. North America sales increased 4% and adjusted segment margin increased 310 basis points due to higher water heater volumes and improved price cost relationship. Our Rest of World segment sales grew 4% in local currency as our recently introduced kitchen products in China were well received by the market. In India, our sales grew 15% local currency in 2023 and benefited from sales of new products, which represented 30% of our sales. Free cash flow grew to $598 million, primarily driven by record profit. We returned $490 million of capital to shareholders with our dividend and share repurchases. Please turn to Slide 5. Our global A. O. Smith team delivered record sales of $3.9 billion in 2023 and adjusted EPS of $3.81, a 21% increase over 2022. North America water heater sales grew 6% in 2023 due to strong demand for our residential and commercial water heater products. The residential unit industry demand increased approximately 6% compared to 2022, as new construction and proactive replacement demand remain resilient. Commercial industry units increased approximately 15% year-over-year as volume of commercial electric water heaters greater than 55 gallons rebounded and aligned closer to pre-2022 levels. We are pleased with our market share strength in both residential and commercial water heaters. Our North America boiler sales decreased 12% against a difficult comp of 28% growth in 2022. We worked down our backlog in 2022 after making significant production and supply chain improvements, which led to elevated channel inventories going into 2023. The resulting channel inventory destocking impacted our residential and small commercial boiler sales. Sales of our CREST commercial boilers with Hellcat technology increased over 50% in 2023. North America water treatment sales grew 2% in 2023 as higher sales and the e-commerce and direct-to-consumer channels were partially offset by lower sales in the wholesale and retail channels. Sales in the prior year benefited from strong shipments as supply chain constraints improved, and we worked down our order backlog, which resulted in elevated channel inventories in early 2023. In China, full year sales increased 4% in local currency. We are pleased with our performance in a continued weak economy. In addition to the successful launch of our kitchen products, we saw double-digit sales growth of our HVAC and commercial water treatment product categories. Our core water heating and water treating products also performed well as replacement approaches 60% of residential water heater sales and residential water treatment sales, particularly consumables, remain resilient. I'll now turn the call over to Chuck, who will provide more details on our full year and fourth quarter performance.

Thank you, Kevin, and good morning, everyone. I'm on Slide 6. Full year sales in the North America segment rose to $2.9 billion, a 4% increase compared with 2022. Higher volumes of water heaters were partially offset by lower sales of boilers and pricing. North America segment earnings of $726 million increased 19% compared with 2022. Adjusted segment margin was 24.8%, an increase of 310 basis points year-over-year. The higher adjusted segment earnings and adjusted segment margin were primarily driven by higher water heater volumes and lower material costs. Moving to Slide 7. Rest of the World segment sales of $957 million decreased 1% year-over-year, including unfavorable currency translation of $44 million, primarily related to China. Segment sales increased 4% on a constant currency basis. Our sales increase was primarily driven by higher sales of kitchen products and water treatment products in China. India sales grew 15% in local currency in 2023, which is approximately 3x the market. Rest of the World segment earnings of $99 million increased 3% compared to segment earnings in 2022, primarily due to higher sales in China. Adjusted segment operating margin was 10.4%, an increase of 40 basis points compared to 2022. Please turn to Slide 8. Turning to fourth quarter performance, we delivered sales of $988 million in the fourth quarter of 2023, an increase of 6% year-over-year, led by higher water heater volumes in North America and higher kitchen product sales in China that more than offset lower boiler sales and pricing. Adjusted earnings in the fourth quarter were $0.97 per share compared with adjusted earnings of $0.86 per share in the fourth quarter of 2022. Please turn to Slide 9. Fourth quarter sales in the North America segment were $738 million, a 7% increase compared to sales in the fourth quarter of 2022, as a result of higher water heating volumes partially offset by lower boiler sales. North America's segment adjusted earnings of $173 million increased 8% compared with 2022. Adjusted operating margin of 23.5% increased 20 basis points compared to last year. The higher adjusted segment earnings and adjusted segment margin were primarily due to higher water heater volumes. Moving on to Slide 10. Fourth quarter Rest of the World segment sales of $260 million increased 4% year-over-year primarily driven by sales of new products, partially offset by unfavorable currency translation of $3 million in China. India sales grew 11% in local currency in 2023, compared to 2022. Rest of the World adjusted segment earnings of $30 million decreased 6% compared to Q4 2022 segment earnings. An adjusted segment margin of 11.5% decreased 120 basis points compared to segment margin in the same period last year. The decreases were primarily due to promotions and advertising supporting the launch of our Dish Washer and Steam Oven products in China. Please turn to Slide 11. We generated free cash flow of $598 million during 2023, an increase of 86% over 2022, primarily driven by higher earnings and lower working capital needs. 2023 free cash flow conversion was 107%. Our cash balance totaled $363 million at the end of December, and our net cash position was $236 million. Our leverage ratio was 6.5% as measured by total debt to total capital. Now I'll turn to Slide 12. As we detailed at our Investor Day, in addition to returning capital to shareholders, we continue to see opportunities for organic growth, innovation and new product development across all of our product lines and geographies. We target strategic acquisitions that meet our financial metrics of accretive to earnings in the first year and return our cost of capital in 3 years. The strength of our balance sheet allows us to continue to invest in ourselves through research and development and capital expansion while pursuing strategic acquisitions. Earlier this month, our Board approved our next quarterly dividend of $0.32 per share. We have increased our dividend for over 30 consecutive years. We repurchased approximately 4.4 million shares of common stock in 2023 for a total of $307 million. We continue our strong track record of delivering return to shareholders. Over the last 2 years, we have returned over $1 billion to shareholders through our dividends and share repurchases. Please turn to Slide 13 and our 2024 earnings guidance and outlook. We are pleased to introduce our 2024 outlook with an expected EPS range of $3.90 and $4.15 per share. The midpoint of our EPS range represents an increase of 6% compared with 2023 adjusted EPS. Our outlook is based on a number of key assumptions, including our guidance assumes that steel prices in 2024 will be a slight headwind compared to 2023. Relative to current steel prices, our projection includes a decline in steel price index in the second half of the year. Our outlook assumes non-steel material costs are similar in 2024, as they were in 2023. Our guidance also assumes a relatively stable supply chain environment, similar to what we experienced throughout 2023. We are monitoring the situation in the Red Sea and Panama Canal and currently have not experienced any negative impacts. We launched our internally designed and manufactured gas tankless products earlier this month, as we mentioned at our Investor Day, these products will be manufactured in our China facility until our North America capacity is completed in 2025. Associated import tariffs and other launch costs will impact North America margins by approximately 50 basis points. We are investing in manufacturing in Juarez, Mexico that would eliminate the tariff in the future. For the year, CapEx should be between $105 million to $115 million. an increase over the last several years due to capacity expansion projects related to our gas tankless manufacturing facility in Juarez, the expansion of our engineering capabilities in Lebanon, Tennessee and an increase in high-efficiency commercial water heating manufacturing capacity to align with regulatory changes coming in 2026. We expect to generate strong free cash flow of between $525 million and $575 million. Corporate and other expenses are expected to be approximately $60 million. Our effective tax rate is estimated to be between 24% and 24.5%. And we expect to repurchase $300 million of shares of our stock, resulting in our outstanding diluted shares of $147 million at the end of 2024. I'll now turn the call back over to Kevin who will provide more color on our key markets and top line growth outlook and segment expectations for 2024, staying on Slide 13. Kevin?

Thank you, Chuck. We project 2024 sales will grow between 3% and 5% compared to 2023, which includes the following assumptions. We believe the U.S. new home construction remains in a deficit, we project it will be flat in 2023. We also assume that 2024 proactive replacement will remain at a level similar to 2023. Therefore, after an approximate 6% increase in the industry in 2023 compared to 2022, we project that 2024 residential industry unit volumes will be approximately flat to last year. We project U.S. commercial water heater industry volumes to increase low single digits as demand for our commercial electric greater than 55 gallons continues its positive trend to pre-2022 levels. In addition, our outlook includes the announced price increases in North America water heating up 4% on most of our water heater products. Price increase for heat pump products is 8%. These increases are projected to be effective late in the first quarter. In China, we believe it will take time for the economy to approve amid weakened consumer confidence in a challenged real estate and housing market, and we have not yet seen signs of significant improvement. Even with the continued backdrop of a weak economy, we project our sales in China will again grow 3% to 5%, and local currency in 2024, driven by resilient replacement demand, growth in demand for our water treatment products and our recently released kitchen products. Our forecast assumes that the currency translation impact will be minimal in 2024. We expect to return to growth in our North America boiler business with a projected sales increase of between 8% to 10% in 2024. We expect to continue to benefit from the transition to higher energy efficient boilers, particularly as commercial buildings look to improve their overall carbon footprint. We predict sales of North America water treatment products to increase approximately 10% to 12% as we expect to grow at 2x the pace of the market. Based on our 2024 assumptions, we expect our North America segment margin to be between 24.5% and 25%, and Rest of World segment margins to be approximately 10%. Please turn to Slide 14. I'd like to thank everyone who joined us at our Investor Day late last year, either in person or via webcast. A recording of the webcast is available on our website. The team and I enjoyed sharing the exciting growth opportunities that we see on the horizon for all of our businesses. A summary of the key topics that we cover are on Slide 14. I look forward to sharing periodic updates on our initiatives including the launch of our gas tankless products. As we look to 2024, we remain focused on our key strategic priorities to advance our position as a leader in heating and treating water around the world. Those priorities are: expand and enhance our high-efficiency product portfolio, including heat pumps for space and water heating, expand our global water treatment capabilities by investing in technologies, people and geographic expansion and deploy capital effectively by investing in ourselves, pursue our active acquisition pipeline and returning capital to shareholders. We have many reasons to be have optimism as we enter 2024. We see strong end market demand in North America for all of our product categories, and we expect to return to growth for boilers and North America water treatment as we believe our customers exited 2024, 2023 with normalized channel inventories. We have begun several capacity expansion projects in North America that will support our growth in the long term. In China, we are projecting a second year of growth driven by innovative new products and resilient demand for our core products. And we expect to continue double-digit growth in India as our premium products and customer service are well received in the market. And finally, this year marks an important milestone for A. O. Smith, as we celebrate our 150th anniversary. What began as a small machine shop in Milwaukee, Wisconsin in 1874 has grown into an innovative, industry-leading global water technology company with more than 12,000 employees. A. O. Smith has a rich and proud history, and we are excited to celebrate it with employees, shareholders, customers and partners across the globe. With that, we conclude our prepared remarks, and we are now available for your questions.

[Operator Instructions] Our first question comes from Michael Halloran with Baird.

I figured after last time where I had issues on my end, getting through, I figured I'd give a pregnant pause there. So make sure you guys could hear me.

We can. I hope they can hear us also.

Great. So two questions here, both on North America. First, could you give some context to how you're thinking about the moving pieces within the residential water heater business between discretionary replacement, new build and then the nondiscretionary replacement pieces?

Yes. I'll touch on that. We don't see much difference in 2024. As we forecasted in our guidance at $9.2 million, new construction, whether it's single-family or multifamily continues to progress, and we see it flat. And the proactive replacement has stayed very resilient. It's been 6 to 8 quarters now. We just received data from it recently, and it continues to move down that path. And of course, the emergency replacement is a nondiscretionary and we expect that to continue. So we look at really 2024 having a very similar outlook as 2023.

And maybe I'll just comment, Mike, that it's been a couple of lumpy years, right? I mean, we've had COVID been a bit of a correction last year. We think the industry this year will be up maybe in that 5.5% to 6%. But if we kind of step back to 2019 and just look at a growth rate of 1.5%, we end up at what we think our outlook is going to be for 2024, along with those assumptions that Kevin just mentioned. So it feels like a fairly stable residential market for us as we go into '24.

Got it. And just to be clear, the 6% was a 2023 reference point, right?

It was '23 over '22. Trip up as we go into the next year here.

No, same page, me, too. So second question then is just putting North America margins in context. I certainly get the 50 basis point headwind from the investments you're making. Could you talk about why the confidence the down steel costs, the lower levels of inflation or limited inflation remaining? And then maybe in the context of what you saw in the fourth quarter and how that will ramp through the year. I know a lot in there, but just looking for a little bit more color around that North America margin guide?

Yes. So we see steel costs as a slight headwind as we go into the year. Steel costs have been kind of in that bandwidth and a cold rolled of $950 to $1,300, $13.50. I mean it's been in that bandwidth at the higher end of that bandwidth right now. So as we come out of the fourth quarter, we're going to see a little bit of help on steel in the first quarter, and then we're going to see steel ramp up again in the back 3 quarters, likely, although we're calling out a slight relief in the back half of the year. Fortunately, we have pricing coming in when steel kind of comes in, in the second quarter. So as we come out of 2023, we're looking at a little bit better margin profile in the first quarter because it feels down slightly and then get helped a little bit on pricing coming in with a higher cost deal. If we kind of look at the cadence for the year, kind of most quarters in North America are within that bandwidth of range or at least pretty close in the 24.5% to 25% bandwidth. I'd say Q1 has maybe a little more pressure and then, of course, as you mentioned, we do have some headwinds just launching our tankless product is about a 50 basis point headwind as we import out of China again through transportation and then continue to promote that product.

One moment for our next question. Our next question comes from Jeff Hammond with KeyBanc Capital Markets.

Hey, good morning, everyone. Just trying to get a sense of feedback from the channel on the March pricing. You guys put through quite a bit. I think we were a little surprised to see a follow-on here, but maybe just speak to how the channel is reacting to it and what's kind of supporting that price increase?

Yes. I would just tell you that our philosophy has always been on pricing that we feel the cost before our customers do. And so as much as steel bounces up and down, there's still other parts of components and other chemicals and so forth. And so our increase is always based on what we have to address going forward with our suppliers. So -- and the cadence, it's off a little bit. We pushed it out to March. And that's pretty rare, but it happens on occasion. Our goal has always been and will continue to be to keep our customers competitive and the price increase along with the timing really reaches that goal for us.

Okay. And then just on the boiler, are you seeing any kind of inflection in boiler demand? Or is this just growth off of easy comps?

It's certainly some coming off some comps. You can remember, first quarter of last year was a pretty good year or a strong quarter for us on the boiler side. And we didn't see destocking until starting in the second quarter. But much of it has to do with coming off some comps, inventories coming down, [indiscernible] getting back to our regular cadence. And we always get a little tripped up on sell out for sell in. You remember, our sell in was down, but our sellout and we felt -- we held our own in the market. So overall, the boiler market is slightly down on some quoting. Residential has been a headwind for us most of the year that we look at turning that around in 2024. But overall, the market is a combination of comps and some of our new products, our CREST with Hellcat technology continues to grow. We outlined how much is growing this year or last year. So a combination of getting back to a normal cadence and some new product offerings is how we get to the 8% to 10%.

One moment for our next question. Our next question comes from Susan Maklari with Goldman Sachs.

Thank you. Good morning, everyone. My first question is going back to that discretionary demand on the residential water heaters. You've obviously seen that in the last several years. You've talked to that holding fairly flat for 2024. When we think about that relative to some other categories such as appliances, where we're seeing that discretionary demand has been weaker, just sort of across our building products coverage. What gives you the confidence that, that will hold this year? And any additional thoughts on where that may trend over time?

Yes. Again, we've been watching it, and it's held pretty steady for a long time. Certainly, as we go forward and look at it, we still see housing renovation, even though things are going to be relatively flat, people are staying in their homes, we think housing or renovation is still going to be a big part of how we go forward. And where it goes long term, we're still trying to get our arms around it. We talked a little bit about some generational issues that we've seen. But overall, right now, in 2024, we're confident that the proactive replacement will stay steady, and we'll continue to monitor it as we continue over the years.

Okay. All right. That's helpful. And then as we come into this year, any thoughts on where channel inventories are, anything that you would highlight there or expectations as we move through the year on that?

Well, I'll start with North America water heating. We entered the year this year pretty strong January. And we think we maybe had a little bit lower channel inventories coming into '23, but we feel like we're in great shape, very normalized on North America water heating. On the boiler and water treatment side, I think we still feel a bit of a headwind as we go through the end of 2023, but feel like we're going to exit the year in a good position of normalized inventories. In China, all the channel inventories are pretty much very normal kind of event for a while and kind of continue in that normalized zone.

Our next question comes from Saree Boroditsky with Jefferies.

Could you just go back and talk about what you saw from the water heater demand or market share in the fourth quarter as shipments in October through November, seem pretty strong versus third quarter results? And then any color on what you saw in January from a shipment perspective?

Q4 came in a little bit stronger than we expected and mostly on the residential side. And we held our own and we got our fair share of that. And so that was a nice positive plus. I think we've talked about being up 4%. I mean, being close to 6% in the residential side of the business. I will see how that actually comes out specifically. And I would tell you, January, it's early. And January was a pretty strong month, particularly on the water heater side of the business. But orders remain strong. I mean, it's -- we continue to track towards our guidance. So in a 1-month view, we feel pretty good about where we're at. And I would just tell you, orders are fairly strong across all of our businesses starting the year. Again, 1 month doesn't make a year, but we're off to a good start.

The Rest of the World margins at 10% or flat from this year despite expectations for higher sales. So maybe just talk about some offsets that you expect to see there?

Offsets for next year?

Yes, on the Rest of the World side on the margin.

Yes. I mean I'll speak to China. So China first, we're expecting growth in China, 3% to 5%. Next year looks very similar in our outlook and that we're going to be investing in new products, promoting new products, looking to have top line growth and kind of maintaining margins in China right around that 11%. So margin -- operating margins in China year-over-year is roughly the same. I think we're really leaning on growth is in India. And maybe when you look at overall rest of the world and you look at our outlook for India, we continue to invest in growth. So we're going to continue to put kind of our -- certainly, we're pleased to be in a profitable position in India. We would like to continue to invest in growth and have growth outlooks of 15% in India next year.

Our next question comes from David MacGregor with Longbow Research.

I want to start by asking about the North American gas tankless business. You talked about its contribution to that 50 basis points of margin pressure. But could you talk about the top line impact, what should we expect in terms of timing and the size of the impact in terms of the initial channel fill? And how are you thinking of that within the context of your revenue guide?

Yes. I mean so we've got a revenue guide of this type back to the overall 3% to 5% growth on the top line. And we're pleased that there's a number of drivers within that growth, and all of them are within the same amount roughly. And if you kind of look at just overall growth on tankless, heat pump Kevin talked about pricing. We've got boilers growing kind of in that 8% to 10%. We've got North America water treatment growing 10% to 12% and then growth in China at 4%. In India, the ones that I mentioned are all very similarly sized so it contributes in a meaningful way to growth, but it's not the largest part of growth in North America next year. I'll just kind of tie it back to -- we're expecting $100 million on the top line over 3 years. So when we get to 2026, we would expect to be incrementally there. It'd probably be a little lumpy as we start out, but we're looking for contributions in year 1.

Yes. Just to add on the tankless side of it. We are building inventory as we speak on the ground, and we'll launch in late March. We're already taking orders for it. And we're excited about it one, that we own the technology we're manufacturing. But more importantly, the first product that we're bringing in the market, which is a condensing premix has all the features that, quite frankly, we've been a little bit hamstrung with our product line. So two inch band, half-inch connection, better flow rates. So all -- our team is excited about getting in the market and being able to compete. So we'll start in March. Early indications from a lot of customers are pretty excited about the product. We're excited about the product. But as Chuck mentioned, this will be a ramp that will start this year and continue to gain momentum over the next couple of years.

Got it. And as a follow-up, I just wanted to ask about China. At the Analyst Meeting, you outlined kind of a 3-segment good, better, best market segmentation model. I wonder if you could just talk about what you're seeing in terms of demand dynamics across those 3 segments right now. I realize AI link is still pretty new. But if you could share what you're thinking and what you're seeing there?

Yes. I'll touch on that, maybe Chuck will jump in on it. We've not seen much change on our mix. And I would tell you that we're -- our good is premium good. And I mean we're not down in the low end of the market. But throughout even the pandemic and even into last year and how we're looking going into 2024, our premium price products, that premium sector of the market has held up. It's not growing, but it's holding. And so our mix looks relatively the same as it has over the last several years. And we feel pretty good about that considering the consumer is not as engaged as it needs to be, and that we look at that as being upside as the consumer confidence grows a bit.

Yes. I'll just put some numbers to that. So I mean, we define kind of the premium sector of the market above RMB 3,000 for electric water heating and above RMB 5,000 for gas water heating and water treatment, which are our core products in China. And the premium sector of the market that we sell, it's been in the 60% to 70% range, a little lower on water treatment right around 50%. But it's been on a ZIP code for quite a while now. So for probably the last couple of years. So haven't seen a change, certainly hasn't decreased, but it's been pretty steady.

Next question comes from Nathan Jones with Stifel.

This is Adam Farley on for Nathan. My question relates to the balance sheet is in a very good position, significantly underlevered with a strong cash position. So what are your plans to optimize the balance sheet? And maybe could you provide an update on your M&A pipeline? I'll leave it there.

Sure. Yes, we are underlevered. We like the position that we're in going into an opportunity for M&A, which we'll talk about. We continue to have kind of a balanced approach. I talked a little bit earlier about investing in ourselves, which are some of the 3 major expansion projects that we have going on with building manufacturing capabilities for gas tankless for investing in commercial high-efficiency capacity and then continue to invest in our R&D facilities in Lebanon, Tennessee. So we continue to make sure we're doing the right things to invest in ourselves and have three major projects going on. We're also doing a bit on the share buyback. We've got $300 million of share buyback in our outlook for 2024. We continue to feel that that's an appropriate component of capital allocation as we're underlevered. And then we're reserving firepower for the opportunities within M&A. We look forward to maybe some opportunities this year. It's always difficult to tell. Certainly, investors' expectations always remain high. We feel like we're in a great position, though, to continue to kind of look for those opportunities as we go into 2024.

I would just maybe add on to that. I mean our pipeline is active. And we continue to look at spaces not only within our core, certainly water treatment but geographic expansions and even levering potentially our customers and footprint that we have in various industries. So a lot of different spots on the board. We're engaged on a pretty regular basis with a number of companies.

And again, just a matter of not yet but when the timing comes about. But again, we look at -- when we look at acquisitions, culture is exceptionally important for us and making sure that we find the right company that fits within A. O. Smith. On top of that, we are going to stay disciplined in making sure that we can return the return to our shareholders. So putting that all in context, we feel really good about the pipeline, and we'll see if we can bring some of those home in 2024.

One moment for our next question. Our next question comes from Andrew Kaplowitz with Citigroup.

I just want to follow up on the 10% Rest of World margin, 11% in China. You obviously spoke about at the Investor Day, 400 basis points of improvement over the next several years. Do you need a better Chinese economy for that margin expansion to kick in? Or do you start to dial down your advertising and promotions soon on the new kitchen products and that will help. How does that work?

Yes. We need a better economic backdrop to achieve that. I mean we really are in a situation now where we feel good about the cost we've taken out at the level we're at. We feel like we can leverage growth going forward, but we need to get the economy back. We need to get housing formation kind of reignited so that we've got a larger portion of the market that is growing in house formation. As you know, most of the water heaters go in when an individual moves into their home even if it's a new construction. We're pleased we've got 60% replacement on the water heating side. So in the meantime, we're very happy with the resiliency of the business at the levels we're at, but we will need some economic help to kind of achieve that expansion.

That's helpful color. And then just shifting gears, North American commercial water heater industry had a good year in '23. So maybe a difficult comparison in '24, but you've dialed in the low single-digit growth. So can you talk about the visibility you have to that end market holding up in '24?

Yes. It held up and had to go primarily back to and we've mentioned a couple of times the greater than 55-gallon electrics. We went to a regulatory kind of change, and we had to get -- the industry had to get its place underneath which it did, and we'll start to benefit from that. But the growth of almost 70% came out of that category and it's almost back to where it needs to be. But if you look at that low single digits, a large majority of that growth is going to be in that particular category as it gets back to a more normalized level that it exited in 2022. But overall, commercial business held up well. Gas business showed some growth. We saw -- we break it down small electrics versus large, small electrics had growth. So each category is still growing, and we expect that to continue. There's still a very big part -- we talked about residential replacement versus discretionary still 85% of that business is replacement market for us. And we have a really nice market share in that particular category. And as you know, restaurants, hotels continue to come back online like they have been, our units are going to get exercised just like everybody else's. And that replacement should continue for the foreseeable future.

Our next question comes from Srikar Vinjamuri with UBS.

I'm on for Damian this morning. So a quick question on North America pricing. So you announced a 4% increase in November and it got pushed to March. I wanted to understand what was the reason for pushing the price increase? Did you get some pushback? What's happening there?

Yes. The details on pricing are really within our strategy here. We always evaluate -- each time we bring a price increase to market. And early on, as we discussed, we make sure that we're addressing costs. We always make sure that we fill the cost before our customers is. And the bottom line where we're at today is what's going to keep our customers competitive and that's really all we're going to say on the pricing side of this.

Okay. And as a quick follow-up on China. You seem to see most of the growth is coming from kitchen appliances and water treatment. So I just wanted to get your color on what you're seeing for water heater demand in China going into 2024.

Yes. Most of the growth that we see in 2024 relates to commercial business on water treatment, water treatment overall, particularly consumables and then we do see some growth in our kitchen products that are newly introduced. Overall, the core products were relatively flat year-over-year. I mentioned a little bit earlier about we've kind of seen the stabilization of maybe what's being sold into the premium side. So we think we're in a good spot for when the economy does come back, but we're looking at relatively year-over-year or flat for our core products.

That does conclude the question-and-answer session. At this time, I would like to turn the call back to Helen Gurholt for closing remarks.
