Good day and thank you for standing by. Welcome to the A. O. Smith Corporation Fourth Quarter 2021 Earnings Call. At this time, all participants are in a listen-only mode. After the speakers presentation, there will be a question-and-answer session. [Operator Instructions] Please be advised that today's conference is being recorded. [Operator Instructions] I would now like to hand the conference over to your speaker today, Patricia Ackerman. Please go ahead.

Thank you, Shannon. Good morning and welcome to the A.O. Smith fourth quarter and full year 2021 conference call. I'm Pat Ackerman, Senior Vice President, Investor Relations and Corporate Responsibility and Sustainability. Joining me today are Kevin Wheeler, Chairman and Chief Executive Officer; Chuck Lauber, Chief Financial Officer; and Helen Gurholt, Vice President, Financial Planning and Analysis. 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 have described in this morning's press release among others. Also as a curtsy to others in the question queue, please limit yourself to one question and one follow-up question. 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 Slide 4.

Thank you, Pat and good morning, everyone. Thank you for joining us today. I'm on Slide 4 and our full year results. Our team delivered record-setting sales and EPS performance despite a turbulent macro environment. Demand for our products in North America was strong and unprecedented inflation-related pricing actions drove sales 19% higher over 2020. The Rest of the World segment performed well in 2021. China improved it's operating margins to over 9%. We successfully navigated supply chain and transportation challenges and improved our delivery performance since the first quarter. We acquired Giant, a water heater manufacturer in Canada, expanding our market share in North America and welcoming a talented group of employees to the A. O. Smith family. With our dividend and share repurchases, we returned $537 million of capital to our shareholders. Please turn to Slide 5. Our global A. O. Smith team delivered record 2021 EPS of $3.02, a 42% increase that was driven in part by a record 22% increase in sales compared with 2020. Demand for our products was robust across geographies. We achieved this strong performance as a result of continued outstanding operational and sales execution from our team despite the challenging environment of component shortages, logistical bottlenecks and material and transportation cost inflation. I want to take the opportunity to thank my follow, A. O. Smith's employees for their ongoing dedication and creativity as we work to overcome these challenges to meet strong market demand and deliver for our valued customers. North America water heater sales grew 21% in 2021 due to pricing actions implemented in response to rising material and logistic costs and strong demand for our products. Commercial industry demand increased approximately 11% due to the resumption of new construction and replacements in the hospitality market segment. Resident industry demand increased…

Thank you, Kevin and good morning, everyone. I'm on Slide 7. Full year sales in North America segment rose to $2.5 billion, a 19% increase compared with 2020. Pricing actions largely on water heaters, represented approximately 70% of the increase. Higher volumes of water heaters and boilers were driven by strong replacement and new construction demand and higher volumes of water treatment products added to segment sales growth. Giant, acquired on October 19, 2021, added $23 million to North America sales. North America segment earnings of $591 million increased 17% compared with 2020. The earnings benefit of inflation-related price increases and higher volumes was somewhat offset by higher material and freight costs. Segment operating margin of 23.4% was a modest decline compared with the 2020 segment margin despite significant cost headwinds. Moving on to Slide 8. Rest of the World segment sales of $1 billion increased 30% year-over-year with approximately 60% of that increase attributed to higher volumes. Our sales increase was positively impacted by lower channel inventory reductions in 2021 as compared to 2020. Channel inventory levels at the end 2021 were at the lowest level in five years. Currency translation of China sales favorably impacted sales by approximately $58 million. Growth in each of our major product categories in China contributed to local currency growth of 24% in 2021. New product introductions in the premium segment of the market, particularly our slim line electric wall hung water heaters and water treatment products that deliver hot and ambient filtered water contributed to sales gains. India sales grew 31% in 2021 compared to 2020. We remain committed to India as a long-term growth opportunity given it's attractive growth characteristics and changes in demographics. Rest of the World segment earnings of $91 million increased significantly over breakeven results in 2020 which…

Thank you, Chuck. As Chuck noted, our outlook assumes the current surge of the Omicron variant subsides during the first quarter, it does not significantly impact productivity or significantly impact the end markets that we serve. With the assumption as a backdrop to 2022, we project revenue growth for 2022 of 16% to 18% which includes the following assumptions: After approximately 8% growth in each of the last two years which is well above the historical average growth rate, we estimate U.S. residential water industry unit volumes will be down approximately 2% from last year as industry demand normalizes. We believe that commercial water heating industry volumes to be flat to slightly down as new construction and replacement installations level off. Our China business performance was strong and stable in 2021. We expect China sales to grow approximately 5% in local currency in 2022 driven by demand of our residential and commercial water treatment products, including our replacement filters as well as range hoods and cooktops. We expect that sales of our residential water heaters in China will be flat to slightly down compared to 2021. We expect our North America boiler sales will increase approximately 10% in 2022. Our expectations are based on several growth drivers; an industry growth of 3% to 4%, we believe replacement demand is 85%. The transition to higher energy-efficient boilers will continue, particularly as commercial buildings improve their overall carbon footprint. In 2021, condensing boilers were approximately 30% to 35% of the commercial boiler industry that represents our addressable market. We believe the potential for the condensing boiler market is to represent 60% to 65% of the total market over time which provides continued opportunity for our leading market share commercial condensing boilers. And new product launches, including a full year of our improved…

Thank you, Kevin, for your kind words. I am fortunate to have spent my entire 39-year career at a terrific company in A.O. Smith and working alongside great people like many of you on this call today. I'm enthusiastic about retirement and one of the key reasons why is my Investor Relations successor, Helen Gurholt. With over two decades of progressively increasing finance experience at A.O. Smith, Helen most recently was Vice President and Controller and led our SEC reporting. You will find Helen to be knowledgeable and personable and I know you will enjoy working with Helen as much as I have. With that, we conclude our prepared remarks and we are now available for your questions.

[Operator Instructions] Our first question comes from Matt Summerville with D.A. Davidson. Your line is open.

Thanks and Congrats, Pat.

Thanks, Matt.

Couple of questions. How should we be thinking about North America in particular, kind of the quarterly revenue and earnings cadence given what's a pretty significant number of moving pieces, how you have incremental price rolling through, how you're thinking about volume across the different product lines? How should we be thinking about that for 2022?

Matt, this is Chuck. So as we kind of look at 2022, overall, the cadence -- when we look at the first quarter, it's going to probably be the most challenging from a margin and perhaps the volume quarter. As you know, China is always weakest in the first quarter with the festival, gains momentum for the second and third quarter and then the fourth quarter is the strongest. You should think of it very similar to that way. Less moving parts in China perhaps because price and costs have not been that much of a move. Back to your North America focus though. North America, a little lighter on the volume in Q1. There are some disruptions. Omicron has, as I mentioned, a bit of our labor force out. And we're going to -- if you look at steel, steel costs mentioned that we're going to still see in the first quarter, we're going to have our highest steel costs that we've experienced as steel has been rising. We, as you know, have a lag when we see this deal. So our Q3 to Q4 steel cost is going to be rising maybe 15% to 20% compared to Q4. So Q1 will certainly be challenged on the margin in North America a bit, though we do have our price increase offsetting that. So we have pricing coming in, got a little bit higher steel. And so Q1 is our most challenged on the margin side. Two through three as you roll out the rest of -- and four to the rest of the year in North America, we do expect steel to moderate just a bit. You've seen the index come down. And so we expect margins to be a little bit stronger in the back three quarters in North America with the price increase in full for all -- really all of the year. So that's basically the roll forward, kind of how to look at 2022 from North America perspective. And we've got -- pricing, I mentioned is about 45%, we believe, on the water heating side effective that we've already seen. And so we've got 55% of that rolling in for 2022. Hope that provides a little better color on how it rolls out.

Yes, it does. And just as a follow-up, you mentioned that inventory levels in China stand at the lowest level you've seen in five years. I guess, do you feel or do you expect to see inventory start to bleed higher? Or is A.O. Smith's objective going forward to really drive that number as low as possible so as to not have a repeat of some of the challenges you had in recent years?

Yes. Our goal is to always keep it at the leanest level that's appropriate to serve our customers in China. It's had a low water mark. We wouldn't expect it to go lower than that at the end of 2021. So as we've said before, we keep a close watch on it. It's at a level where we feel is about as low as it's going to go to make sure we're serving our customers.

Thank you. Our next question comes from Scott Graham with Loop Capital Markets. Your line is open.

Yes, hi, good morning. And hearty, congratulations to you, Pat; you've been phenomenal in your job.

Thanks, Scott.

I have a couple of questions for you all. I guess the first one is on the North American business. It looked like the first two months of industry shipments in resi water heaters were up and your chart shows volumes down in North America for the quarter. Could you maybe give us a little more color on that?

This is Kevin, Scott. I mean, as we discussed on our Q3 call, we had a challenging Q1 and we had been making progress through Q2 and Q3 and we fully expected that to carry over into Q4. It lagged a little bit. And so that's what you're seeing. That is not indicative of order rates. That's not indicative of customers. But it did lag a little bit. We expect to pick that up as we get into 2022. And I guess the comment I would make is our customer bases are solid. We've had no issues, no losses. And I believe based on customer feedback, we really serviced our customers well throughout this pandemic and make sure they have the right products they needed. And what we did at the end of this year as the -- our supply chain started to stabilize and so forth. We had some allocations out there for the -- for most of the year and we took those allocations off in December. So that's going to help drive maybe some additional orders as we get into Q1 but bottom line, I think we're in good shape. And as the industry normalizes and gets out of this turbulent sector, I think everything will move back to a much more of a normal cadence and a normal share output for us.

Okay. Two other questions really. I know you have to start the year carefully with some of your estimates and certainly, that seems to have read through to a couple of the line items. I guess I'm thinking that when you say commercial flat to slightly down, I guess I'm kind of wondering where you're coming from on that one because the -- we're still -- I guess Omicron now key part of that but it just -- it feels like we're going to have a full year of reopenings, possibly even incremental reopenings versus '21. Just sort of wondering why you would think that, that would be a flat market for you.

Well, I'll touch on that and then maybe have Chuck jump in as well. When you look at -- we had a lot of reopenings in 2021. We had a very strong market. And as we go forward, it's a forecast. We believe that things will be a bit more normalized. Probably some of the proactive replacements won't be there. And so as we look out, a very strong 2021, we think that's just going to peel back in 2022. But again, flat coming off a very strong year, Scott, is pretty positive.

Thank you. Our next question comes from Susan Maklari with Goldman Sachs. Your line is open.

Thank you. Good morning, everyone and Pat, I'd like to add my congratulations as well to you.

Thanks, Sue.

Good morning.

Good morning. My first question is you mentioned that you have taken a lot of your customers off of allocation in North America in December. Can you just give us some color on where you think channel inventories sit? And how do you expect that your order rates could trend as those allocations have been removed?

Let me touch on that one as well. One, we're very specific on our order -- on our inventories in China because we have really terrific visibility there. North America, it's more of a -- we don't have the same visibility but based on the input that we have from our customers and so forth that the inventories are basically in line. There's probably some gaps here and there. For the most part, I think the allocation just frees up maybe some orders. I'm not going to put a number on it, quite frankly. But I do think we have limited some of our customers and try to be predictable for them, getting the right products to them, making sure that their deliveries were on time. So again, I think it's a positive thing for our organization as we enter into 2022, removing the allocation and kind of getting back to business as normal. And so that's kind of where we're at. No specific number, I think I would want to add to that.

Got you. Okay, that's helpful. And then, as we do think about steel perhaps moderating or sort of coming off of this peak as we move through the year, how should we expect price will sort of trend with that? Do you think that as the volumes come off on the residential side potentially you'll have to give back any of this price? Or do you expect that it will be fairly sticky?

Yes. It's -- we've never had these sort of price increases like we've seen in the last couple -- in this last year, of course. So it's a little bit difficult to predict. We can kind of look at historically what's happened. Historically, we've generally been able to hold share in margin and we react to the cost changes as necessary. So a bit hard to see how it plays out. We've got non-steel cost in logistics and freight that even as steel costs have come down since our last call, we've only seen pressure and increase on all other non-steel costs. We really have seen those surge a bit in the last quarter. So those somewhat offset some of the relief perhaps that might be happening a bit of moderation on the steel side.

Our next question comes from Damian Karas with UBS. Your line is open.

Hey, good morning, everyone. Congrats on the year. And Pat, best of luck in your retirement.

Thanks, Damian.

So I wanted to ask you about some of your comments on China. So you're expecting 5% sales growth there but you mentioned water heater volumes flat to slightly down. Could you just talk about little bit about your key assumptions driving your forecast there?

Sure, sure. Yes, I mean, water heater volumes in China have been flat to down. When we look at the full year demand and I'll just kind of talk about what the overall 2021 consumer demand as best we measure through our channel, it probably was up 1% to 2% the demand itself. So underlying demand when we get to the 5%, you can kind of think of it as 1% to 2%. There's a bit of pricing in China. We haven't nearly seen the cost pressures as we've seen in North America but that's perhaps another percent. And then when we think about kind of the new products, we've got some new products we've introduced. We've got the products I mentioned earlier in the statement on electric that are doing well and the gas products that are doing well, range hoods, cooktops, commercial water treatment and water treatment overall, we feel pretty positive about which kind of fills that gap to get you to that 5%. Year-over-year currencies, we expect to be roughly flat, equal year-over-year. So that's kind of the bridge to kind of get up to that 5%.

Okay, great. That's helpful. And then on water heaters, specifically in China, maybe you could just help us understand a little kind of where mix is today compared to the pre-2019 peak levels, if you will. Obviously, kind of you mixed down after that. But maybe any color around kind of the mid- to premium price mix today relative to the past would be helpful.

Yes. We're -- so we're not at the peak where we were in mix in the peak years before 2019. Premium segment of the market was higher percentage of the segment of the market as we measure it at that time but we are coming out of the trough. So we've got a year-over-year improvement in mix planned in 2022. Q4 was positive on mix. And the introduction of a couple of the new products we've just put out there help our mix because they're in the premium segment. So we're not at the peak. We're certainly not at the trough. We feel really good about the momentum coming out of it and positive about the new products coming into the market.

Yes. I would just add, I mean it's new products across our electric line, our gas tankless line, our water treatment that has done substantially well and continues to grow. And so -- and then the kind of what I would call the newer segments. Our commercial water treatment continues to do well and close over to $40-plus million. And then Chuck mentioned range hoods and cooktops which are gaining momentum. So overall, there's still going to be a COVID issue that we'll have to work through there and some spotty shutdowns that happened. And that may deal us a setback. There's still some derisking. But you put it all together, we came out of fourth quarter pretty well. We have some really good products on the premium side that are just getting into the market fully. So we feel real good about the mix and where it's going and hope to get back to those '19 levels soon.

Thank you. Our next question comes from Nathan Jones with Stifel. Your line is open.

Good morning, everyone. My congratulations to Pat and welcome to this part of the team to Helen. I did want to follow up on steel prices. I know you guys are talking about steel indices flattening out. But I think you have more exposure to coil steel prices which have actually come down pretty substantially. Is that a potential significant tailwind from margins as we get into maybe the second half of the year once you've run through the higher-cost steel and the inventory? And how is that balancing off against the inflation that you're continuing to see in other inputs?

Yes. I mean our input on steel is about 70% cold rolled, 30% hot rolled. So those are -- those are the indices we're really tracking. And there, we've seen some moderation. We haven't seen it come down a great deal but we've seen some moderation. Year-over-year, our steel is going to be up 50% in 2022 on average compared to 2021. So we still have that steel pressure there. Right now, I mean, it's early in the year, right? So we're looking at the increase of non-steel cost components, logistics. We really haven't seen any relief on that. If we just kind of look through the rest of the year, our best projection would be if there is some moderation in steel on the index that we have seen a bit that the offset is largely in the non-steel components. And so we're not in our outlook calling for any -- we're calling in our outlook when we look at it, that Q1 is probably the most challenged and then it really -- the margins sort of flatten out after that -- after we get over that kind of one quarter where steel is the highest.

I guess my follow-up then around the margin guidance for North America which is down a little bit from 2021. I think given you were chasing costs up last year, you had some disruption in your manufacturing processes early in the year last year. I might have expected a little margin expansion in 2022. Can you maybe just discuss the puts and takes that are going into seeing margins a little bit lower in North America in '22?

Sure, sure. So they are lower in our guidance and what -- let me just do a little reconciliation because if you exclude -- and I mentioned the noncash pension adjustment, that's about $10 million that you'll see in our GAAP to non-GAAP reconciliations. That will affect the margins a bit. And if you look at the Giant acquisition which is performing great as we expected, performing well but it doesn't have quite the same margin as the rest of the North America business. Reconciling for those two really get us back to adjusted margins that are flat compared to 2021. So 2022, North America is roughly flat compared to 2021. And that's with continued growth in North America water treatment and some of those other businesses that we're looking to expand our margin year-over-year. So the kind of expectation it may gone up, we're really looking at flat and some of those other non-steel costs that we're seeing are really filling that gap.

Thank you. Our next question comes from Mike Halloran with Baird. Your line is open.

Good morning, everyone. And congrats, Pat. It's been an enjoyable -- what decade plus, I guess but I've really enjoyed the relationship. So, thank you.

Thanks, Mike.

So maybe a similar line of question on China, Chuck, maybe just could you give the bridge on the China margins and obviously, 10% is a nice increase here but what are the puts and takes going from this year's to next year's margin levels?

Yes, I can do that. I mean it's really -- it's up about 100 basis points. So we're kind of -- we're looking to expand from 9% to 10%, mostly on volume, mostly on volume and mix. We got the products that we mentioned earlier and that they came into play in volume and mix. So we overcame a bit in 2021 to 2020. I mentioned the social insurance. That's about $12 million for the year. So we like the progress that we made in '21 to get us to 9%. And then it's really volume and mix and leverage on the top line that gets us to 10%.

That makes sense. And then shifting to North America. When you think about the tank, tankless heat pump dynamic in the water heater side, the residential water heater side, any movement as you think about it through this year? And how you're thinking about -- through last year, excuse me, how you're thinking about it this year. Any real change in the momentum that you've been seeing in any of those business lines relative to each other?

I would say on the residential side, probably not any tank momentum. Heat pumps have been growing year-over-year, becoming more popular. Obviously, there's more incentives out there and that's moving in the right direction. So we're in a good position there. And I would say, maybe on the commercial side, we're starting to see a bit more commercial heat pump up there. But let's step back, we still have a great decarbing footprint called condensing water heaters and condensing boilers. And that's also trending well because there's so many applications that you really need the output and the heat of a gas-fired product and being able to provide condensing boilers and condensing commercial water heaters, also priced opportunities. So commercial, I think you're going to continue to see just high efficiency growing and on both gas and on the kind of the heat pump side.

Thank you. Our next question comes from Jeff Hammond with KeyBanc Capital Markets. Your line is open.

Hey, good morning, everyone. Best of luck, Pat.

Thanks, Jeff.

So, just first on supply chain. You mentioned a couple of times stabilization, moderation in the headwinds. Can you just speak specifically to what you see as getting better here near term?

Just overall, you can't make any of our products without every component. And so it's -- and when I say that I'm smiling here. But overall, as you start to become a bit more predictable, as our suppliers become a bit more predictable. And so that's what's been -- and then just some of the volumes coming up. We came out of a big freeze that impacted farm and oil-based products. And then steel was running behind but we're starting to see all these key components moving in the right direction. And so that's the stabilization. We're still very tactical, tracking orders and making sure we're looking for alternatives but we've been doing that for a year and it's worked out pretty well for our team. So overall, that's what stabilization looks like. That's why we were able to remove the allocation from our supply chain. And then, I'm going to tell you we're going to have pockets of disruption occasionally here and there. We'll have to keep working through that. But that's where it's at. It's getting incrementally better. It's getting incrementally more predictable. Our suppliers, just like us, are stepping up their game in production and deliveries. But it's incremental. And we feel as we enter 2022, we're in better shape in 2021, albeit we'll have to see how the Omicron surge impacts that. But as of right now, there hasn't been a large issue for us.

Okay. And then just back on this kind of steel and pricing dynamic. It seems like cold rolled which I think is your biggest input, is down like 15% off of year-end pricing. And just if that sticks, when do you start to see, one, the benefit of that? And just remind us how the material price formulas work with the DIY customers where some of that pricing -- when that some of that pricing might roll off?

So the decrease we've seen so far that it still has come down. We probably -- we will not see that until we get it probably into the middle of the second quarter. So that's from a cost perspective. And then who knows where it will go from there, right? So it's gone down a bit. I'm not sure our assumption is that it kind of stays at that level through the rest of the year. We've got -- we have certain customers that have pricing formula that represents maybe 25% of our water heater volume. And so the cadence on that follows similarly to kind of when you see steel indexes move.

Thank you. Our next question comes from David MacGregor with Longbow Research. Your line is open.

Yes, good morning, everyone. And Pat, thanks for all the help along the way. It's been great working with you. I wish you all the best in your retirement.

Thanks, David.

I guess I just wanted to build on a couple of other questions that have been asked at this point. And maybe for starters, go back to the discussion around China and mix and you talked about the fact that you're seeing a stronger mix with the premium product. Clearly, that's a reflection of new product that you've introduced out there. But are you seeing a similar trend across the broader market? In other words, is the Chinese consumer mixing up again? Or is this really AOS specific?

Yes. Based on the data that we've seen and again, I am going to relate it to more of the appliance side of the business. We see almost every category on a year-on-year basis, mixing up. So that's a positive trend that says a lot maybe consumer confidence and so forth in China. But yes, we are seeing it. It's not just in our categories but others that we don't participate in.

Yes. It's not back to the peak but it's a couple of quarters now where I think we can start calling it a trend because we've seen an uptick.

Yes, that's encouraging. And just on China, can you update us in terms of how you're approaching distribution and the growth of distribution in terms of 2022, what should we expect there in terms of new doors?

Yes. So we really are focusing on two pieces really. When you think about kind of the Tier 1 and Tier 2 cities, we are -- we're really looking at store efficiencies there. So we're continuing to be focused on store efficiencies. We're probably going to take out a bit more stores in 2022. We're at that pace. We've been on that pace for a number of years now. We're probably in the 200 to 300 store taking out in 2022 compared to where we're ending the year in 2021, just not quite 6,000 outlets. On the other side, we're really looking to grow geography in the Tier 3 to Tier 6 cities. So think of that as low-cost counters. We're just -- we're not having a promoter. It's very opportunistic. And those footprints, that's growing in the neighborhood of maybe 500 but don't do the math equal to the Tier 1 and Tier 2 but it's certainly opportunistic and it's where we're really looking to continue to expand.

Thank you. Our next question comes from Andy Kaplowitz with Citigroup. Your line is open.

Good morning, everyone. Best of luck, Pat.

Thanks, Andy.

Can you talk a little bit more about the competitive environment you're seeing in North America? You have a very strong positioning in the core water heater market here but you've also been aggressively raising price and you do have some competition ramping up their own capacity now. So how sticky can your pricing be as inflation starts to normalize a bit? And should we be at all worried about competitors ramping up their own capacity?

Well, I worry every day. So -- and I'm not being flip but I mean if you look at our business, we've been competing for seven years in this industry. We continue to get up every day and focus on A. O. Smith and A. O. Smith's customers and our brands. And so there are clearly some competitors coming into the market. We're going to continue to focus on what we do best and that's bringing innovative products to market, high service levels and making sure that we grow profitable with our customers. And I'll go back to the recent statements that we just really talked about is we had no customer loss. I really believe that we really -- we've taken care of our customers in a professional way and manage their expectations. And again, I always go back to this industry isn't about residential, gas and electric, isn't about just standard commercial. It's about bringing a portfolio of products to our customers. And not only residential and commercial but the high technology, newer products like heat pumps and condensing products that we continue to bring to market, perfect example is healthcare technology on our CREST boiler. All those things matter and we package that up together. We believe when we compete in the market, we have a value proposition that meets our customers' expectations and helps them grow their business.

And the only additional comment I'll make to that is and we called it out in our slides is that our R&D spend is over $90 million. And that's on water heating, water treating and we're really focused on those markets and as Kevin said, being the leader in the product technology.

And maybe for my follow-up. North American boiler sales, you talked about up 10% in '22 after a good year in '21. So maybe you can talk a little bit more about the sustainability of the growth trends that are helping you in that business. I think historically, it's been more of a mid-single-digit grower. And do you think you'll see any direct impacts from the infrastructure bill? And if so, when could they begin to occur?

Well, I can tell you, we've seen certain segments. We talked about the educational segment. Last quarter, that's been certainly been helping us in providing an opportunity. We're seeing more government institutional segments start to grow. So we are seeing some of that maybe that stimulus or that we're talking about in the marketplace. That's what's led to our record backlog that we have today. And that's going to stay with us, I think, at least through 2022. I mean we're looking at a 10% growth rate. And so overall, there are some stimulus out there. There's also just some pent-up demand that may go back to the pandemic that we're filling that gap as well. And again, the replacement market is 85%. So you're going to have that natural replacement market continue. So overall, the boiler market looks strong. Orders are still good. Quoting activity is still good. So overall, entering 2022 in a really good position in the boilers segment.

Yes. I mean the thing I'll add on to that is I mean that 10% growth, there was some pricing that we did do on the boiler side of the business also. So there's a bit of carryover pricing that helps us a little bit but we still see growth in the boiler market.

Thank you. Our next question comes from Bryan Blair with Oppenheimer. Your line is open.

Good morning, everyone. Pat, thank you very much for your help over the years. It's been a pleasure working with you.

Thanks, Bryan.

Good morning.

I apologize if I missed this. Did you cite run rate North American water treatment margins or the expected margin step-up as that business continues to scale double digits in '22?

Yes. We haven't, I don't think but margins are around 11%. They were approaching 11% in 2021. So we're pleased with the progress that we made, leverage and volume, the acquisitions to continue to move forward on that and we're expecting about 100 basis points expansion in 2022.

Okay, appreciate that. And circling back to commercial boilers. Any feedback you can offer on the reception and acceptance of your Hellcat technology since that's been out there and how that factors into the backlog build that you've had and how we should think about the -- I guess the cadence of first versus second half growth netting to that 10% range that you've guided given your backlog position bidding activity, et cetera?

Well, the Hellcat technology has been accepted and received very well by our contractor mechanical base. And so -- but that was at the later part of the year. So we really look forward into 2022 of having a full year with this new technology. And just to go back to it, I think we stated in our remarks but it's not only higher efficiency but start-up that could take two to three hours, it takes 20 minutes sometimes now. Maintenance, it helps us get through the maintenance and it adjusts, so you don't have to go out there and do manual adjustments and the overall cost. So we're excited about it. It's a first to market, a first mover. It's truly technology different than what's in the market today. We've built it on a terrific product like the CREST. And we just see that continuing to grow and gain momentum, particularly in the specified side of the business.

Yes, not specific to growth but the cadence of the boiler business is typically, Q3 and Q4 are the strongest quarters and we still expect that in '22.

Thank you. Our next question comes from Larry De Maria with William Blair. Your line is open.

Thanks. Good morning, everybody.

Good morning.

And certainly, best of luck to Pat.

Thank you.

Yes, I hope everyone gets a nice time for a field trip [ph]. So, I was kind of curious, I know you touched on this but as it related to China with inventory of five-year low, I believe you said but only looking up 5% for the market. I mean I know you're confident enough but can you delineate between consumer demand and channel fill? And are we holding the channel back at all from refilling? Just seems like there might be some potential upside there.

Good question. We don't believe we're holding the channel back. I mean I will say we had a strong order rate at the end of December that we certainly did get out in January. But we're not -- it may go up a bit. We don't expect it to go lower. So as we kind of think about 2022, channel inventories do get a bit lumpy but they've been really honed down to a pretty lean level. And if anything, we expect it to slightly go up but we're going to keep that in a close watch.

Okay. And then you guys also mentioned the impact of Omicron, I think, in the fourth quarter into the first quarter. If you could just kind of clarify that is it mostly in North America, is it little bit in China also? And how meaningful is that impact?

Yes, it's primary. It's almost exclusively in North America, particularly with the number of people that we have out. So China, again, very little but again, it's spotty, it depends on the region. India is the same way but really, the Omicron surge has really impacted our North America businesses. And we're working through it. It hasn't peaked yet but we hope that we'll start to see it peaking, it will come down and we'll get through it in the first quarter and kind of put this phase of COVID in the rearview mirror.

Thank you. And I'm currently showing no further questions at this time. I'd like to turn the call back over to Helen Gurholt for closing remarks.

Thank you for joining us today. Let me conclude by reminding you that our global A. O. Smith team delivered strong sales and earnings despite many challenges in 2021. We are optimistic about our results in future periods based on a durable strategy, robust demand for our products as well as strong execution of our strategy despite an environment challenged by component shortages, logistical bottlenecks, inflation in both materials and transportation costs and pandemic-related challenges. We look forward to updating you on our progress in the quarters to come. In addition, please mark your calendars to join our presentations at three conferences next month; RW Baird on February 22, Citi on February 23 and Barclays on February 24. Thank you and have a great rest of your day.

This concludes today's conference call. Thank you for participating. You may now disconnect.
