Good afternoon, and welcome to Shoals Technologies Group Fourth Quarter 2022 Earnings Conference Call. Today's call is being recorded, and we have allocated 1 hour for prepared remarks and Q&A. At this time, I would like to turn the conference over to Mehgan Peetz, Chief Legal Officer for Shoals Technologies Group. Thank you. You may begin.

Thank you, operator, and thank you, everyone, for joining us today. Hosting the call with me are CEO, Jason Whitaker; President, Jeff Tolnar; and CFO, Dominic Bardos. On this call, management will be making projections or other forward-looking statements based on current expectations and assumptions, which are subject to risks and uncertainties. As you listen and consider these comments, you should understand that these statements, including the guidance regarding full year 2023, are not guarantees of performance or results. Actual results could differ materially from our forward-looking statements if any of our assumptions are incorrect or because of other factors. These factors include, among other things, the risk factors described in our filings with the Securities and Exchange Commission as well as economic and market circumstances, decreased demand for our products, policy and regulatory changes, industry conditions, current macroeconomic events, supply chain disruptions and availability and price of our components and materials. Although we may indicate and believe that the assumptions underlying the forward-looking statements are reasonable, any of the assumptions could prove inaccurate or incorrect and therefore, there can be no assurance that the results contemplated in the forward-looking statements will be realized. We caution that any forward-looking statement included in this discussion is made as of the date of this discussion and do not undertake any duty to update any forward-looking statements. Today's presentation also includes references to non-GAAP financial measures. You should refer to the information contained in the company's fourth quarter press release for definitional information and reconciliations of historical non-GAAP measures to the comparable financial measures. With that, let me turn the call over to Jason.

Thank you very much, Mehgan, and good afternoon, everyone. Before I make my formal remarks, I would like to thank our employees, customers, vendors and shareholders who have each played a role in the tremendous success that Shoals has achieved over the past several years. Without your contributions and support, we would not have the company that we do today. I'll start off with some key highlights from our fourth quarter and full year results and then discuss the progress on our CEO transition. Following that, I'll turn it over to Jeff, who will provide an update on our business, growth initiatives, current market conditions and operational focus areas for this year. Dominic will then wrap up with an overview of our financial results for the fourth quarter and outlook for 2023 before we open the lines for questions. Shoals set new records for revenue, gross profit, adjusted EBITDA and adjusted net income in both the fourth quarter and full year. Compared to the prior year periods, fourth quarter and full year revenue grew 97% and 53%, respectively. The increase in revenue was driven by growing demand for solar and EV and continued share gains for our products. The strength of demand for our products is underscored by the fact that Shoals' annual revenue growth has increased each year since we've been public, despite having more than doubled revenue over the past 3 years. Versus the same period last year, fourth quarter gross margin increased more than 950 basis points to 42.7%, and adjusted EBITDA margin increased approximately 840 basis points to 31.8%. The margin expansion we achieved in the fourth quarter was the result of greater leverage on fixed costs driven by higher sales volumes and increased proportion of revenues attributable to our combine-as-you-go solution. Now turning to an update on our CEO transition. In November, Shoals announced that I will be stepping down from my role as CEO this year for health reasons. My last day with the company will be March 15. As previously announced, the company has appointed Shoals President, Jeff Tolnar, as Interim CEO. Jeff was previously SVP of EV Solutions and led the successful launch of our EV Solutions business. Prior to Shoals, Jeff held senior management positions with Fortune 100 companies and cofounded or led several startups, including Greenlots, which was acquired by Shoals. In his new role as President, Jeff is responsible for global sales, product development, engineering and operations. He and his team are accountable for ensuring the operational milestones required to achieve the company's strategic goals are met. The Board is currently working with Spencer Stuart to vet several highly qualified candidates and intends to select a permanent CEO following completion of an extensive search and vetting process. With that update, I'll turn it over to Jeff.

Thank you, Jason, and good afternoon, everyone. It's a pleasure to be with you all today. I'll start with a review of our performance of our core combined as-you-go solutions in the quarter then discuss the status of our new product introductions for 2023. Following that, I'll provide an update on our international expansion efforts, review conditions in our core solar and EV markets and then close with an overview of some new operational initiatives that we are implementing. System Solutions revenue grew 150% in the fourth quarter of 2022 versus the fourth quarter of 2021, reflecting strong growth in U.S. utility scale solar demand and continued share gains by our products. During the quarter, we converted 3 additional EPCs and developers to our combined as-you-go system, bringing the total number of BLA customers to 36, with an additional 14 in transition. We believe that the majority of EPCs and developers in the U.S. will be using our system in 2023. Our new wire management product line contributed to growth in the quarter. Our wire management products' attach rate to BLA has continued to grow as customers increasingly recognize that they install faster and are more reliable than conventional solutions. We recently surpassed 800 megawatts of deliveries for projects using our clips, and we expect continued growth throughout 2023. Our battery storage products also contributed to growth as we began shipments during the fourth quarter for the 1 gigawatt DC storage project awarded to Shoals in the third quarter of 2022. More solar projects are incorporating battery storage, and our sales team is actively quoting battery storage products for our solar customers. We recently added dedicated sales resources for energy storage, which we believe will help drive higher sales volumes. Our team also plans to launch an eMobility energy storage…

Thanks, Jeff, and good afternoon to everyone on the call. Fourth quarter revenue grew 97% versus the prior year period to $94.7 million. The higher sales volume was primarily driven by increased demand for our solar solutions but also benefited from EV charging solutions that were launched earlier in the year. System Solutions revenue increased 150% year-over-year and represented 86% of total revenue versus 68% in the prior year period, reflecting continued market share gains for our solar combine-as-you-go system. Gross profit increased 154% to $40.4 million compared to $15.9 million in the prior year period. Gross profit as a percentage of net revenue grew more than 950 basis points to 42.7% compared to 33.1% in the prior year period driven primarily by increased leverage on fixed costs and a higher proportion of revenue from System Solutions. Fourth quarter general and administrative expenses were $14.9 million compared to $11.0 million during the same period in the prior year. The year-over-year increase in general and administrative expenses was largely driven by higher payroll expense in connection with incentive compensation and planned new hires. Net income was $118.3 million in the fourth quarter compared to a net loss of $2.2 million in the prior year period. Net income benefited significantly from the $110.9 million noncash gain we recorded in the quarter in connection with the termination of the tax receivable agreement, or TRA, that Shoals had with Oaktree and our founder, Dean Solon. Over its life, the TRA could have required us to make more than $500 million in cash payments to Oaktree and Mr. Solon, so terminating the agreement eliminated a significant future liability for the company. Adjusted EBITDA increased 167% to $30.1 million compared to $11.3 million in the prior year period. Adjusted EBITDA margin increased by approximately 840 basis…

Thanks, Dominic. I'd like to close again by thanking all of our customers for their confidence in Shoals, our employees for enabling us to effectively serve our customers and our shareholders for their continuous support. As we move on from a record performance in 2022, we could not be more excited about the opportunity ahead. Furthermore, beyond our still growing core BLA products, we've only started to penetrate the opportunity for our new solar and EV products. With the product line building, demand is increasing as we extend our global reach. Importantly, we believe we've only started to realize the full power of the Shoals platform. I'm incredibly proud of what Shoals has accomplished over the past several years and that I will leave the company commercially, operationally and financially stronger than it has ever been. There is no question that the future is extremely bright. And with that, thank you, everyone. I appreciate your time today. We'll now open the line for questions.

[Operator Instructions]. The first question comes from Maheep Mandloi of Credit Suisse.

This is David Benjamin in for Maheep Mandloi. Congrats on the quarter, guys. I was wondering if there's any additional upside in the potential revenue guidance should UFLPA resolve faster than expected.

So this is Dominic. Thanks, David. In terms of our guidance, we're very comfortable with the guidance range that we've given, in terms of our backlog, awarded orders and ability to drive that revenue number. As we've talked about before, we haven't seen a significant delay of panels and projects associated with our revenues. So we're holding firm to the guidance that we've issued today.

Okay. Great. And one more question about margins. Can you talk a little bit about the ramp-up in your manufacturing facility and talk about kind of what we could expect for long-term margins when that's fully ramped?

Yes. So from a margin perspective, we actually guide for our production capacity that we built out ready to get about a $500 million number, as you see implied in our guidance for this year. We are looking at facilities to take us to another level and really expand further and look at geographic diversity and things like that. But what we've said and guided to, we haven't issued really long-term guidance, but we do believe a 40% gross margin is achievable, and we like having a 30% EBITDA margin. And so we'll keep that in mind as we continue to look for additional facilities.

The next question comes from Philip Shen of ROTH MKM.

I think you mentioned in your prepared remarks that you reached record backlog in the first few weeks of January. I was wondering if you could talk about what those bookings look like and importantly, also how you expect the bookings to trend. It seems like there was a big push in the first part of the year, and perhaps you could talk about the drivers of that activity. And ultimately, if you can even share what that record backlog number is, I think that would be fantastic.

Phil, thanks. We won't share the specific numbers from January and February. What I think is really important to note is when you look at where we wound up the year last year, so $428 million, we had a book-to-bill of 1.3. That's consistent with prior years. And then we also had the additional shipping and outflows of product in fourth quarter. That was an upside. That was a positive. And some of the orders that we were expecting to convert from pipeline to awarded order shifted into the first couple of weeks of January. So just by having those couple of weeks, we'd be having a very different discussion about this. And that trend has also continued throughout '23 so far, 6 weeks in. So we feel very strongly about the products that we have and the market adoption of those.

Great. And so when you think about your guidance for the year, what percentage of that do you think is covered in the backlog that you have currently? It sounds like it could be as high as 85%, 90%, but wanted to get a feel for that. And then would you expect the vast majority of that backlog to be recognized this year? And then perhaps also one more, if I may. What percentage of that backlog do you think -- I think maybe the product question I was asking about, but if you can share, what percentage might be impacted by UFLPA, if any?

So let me unpack a little bit of that, Phil. I mean the main thing is that the guidance range that we've issued is -- really takes into consideration the $428 million of backlog at the end of December 31, 2022. The main thing is that we've said before, it's typically a 9-, 12-month window to really turn that awarded orders and backlog into the revenue. And we don't see that changing at all. It's really consistent. There's always a little bit of a bell curve with that, but we fully expect to realize that $428 million in the year. So there are some things that we still have go get. We haven't issued the exact breakdown of what percentage is yet to be found. We do believe that we'll be able to secure some additional orders that we have visibility to. But as we go forward in the year, if we don't secure those orders here in the next few months, the likelihood of being able to really get those into this year might be more and more limited. So at this point in time, we're very comfortable with the revenue range that we've guided to. The UFLPA, the panels, as we've said last year in previous quarters, we haven't seen a significant impact on our business. Projects have gone forward with our installations and ordering our products even if panels were slightly delayed. To this point, I'm not aware of panels being refused. I think there were just delays. I think even in Q4, we saw some more panels being released. So at this point in time, there's really no separation or variation from the guidance that we've given. We think that we've got good line of sight to all those things and are very comfortable with the range that we've provided.

Great. One last one here. As it relates to BLA 2.0, could you share a little bit more color in terms of what percentage of your overall BLA sales in '23 you think could be 2.0? And now that you're taking orders and so forth, can you talk about maybe the price premium that 2.0 might be getting over the original BLA?

Yes. Thanks for the question, Phil. We're pretty excited about BLA 2.0 being launched and quoting globally at this point. As mentioned, we expect first revenues in second quarter. Remember, the product itself is a bundled solution. So the increase in ASP will depend upon what portions of the bundle are selected by the customer base. We do expect a 10% to 20% ASP based on the portions of the kit that are taken by the customer base. And we're excited about the quoting volume even out of the gates, and we expect that to continue throughout the year.

Phil, Jason here real quick. One thing I want to add is when you look at the BLA 2.0, kind of pointing back to a combination of what Jeff and Dominic said is, the backlog and awarded orders that we closed out at the end of 2022, it doesn't really represent what I would call BLA 2.0 because we just recently started quoting out that product, as Jeff stated, at the beginning of this year. So specifically on the question about 2023, that particular range is based upon exactly what the book looked like at the end of this -- at the end of last year, Phil.

Okay. Thanks, Jason. Best wishes to you. And then thank you, Jeff and Dominic as well.

The next question comes from Jordan Levy of Truist Securities.

Maybe just to start out by getting your thoughts on the EV solutions business and the ramp there as you move that segment through '23. I know you mentioned in your remarks, there could be some lumpiness in that segment. But I just wanted to kind of get your broad thoughts about contributions from that and also how customer demand has been trending there.

Yes. Thanks, Jordan. That's my baby. So I'm pretty excited about that. We remain very excited about the eMobility, the EV charging business. It's been a focus area for us in the past year. We launched products last year and very excited about the uptake that we've seen. It's certainly bolstered by the 2021 infrastructure bill. If you recall, we mentioned that there's close to $7.5 billion being poured into the eMobility business itself in primarily corridor charging and school bus electrification. And we're seeing upticks in quote volumes for both of those, and we're also seeing our primary offering being adopted by the fleets, which are some of the initial evolutionary areas of electrification as well. So we feel very excited about where we're at. As mentioned, it's still early post launch. So with any new business, any new product offering, it's going to be a bit lumpy to begin with. As we get more certainty and more predictability in our forecasting, then we may release a bit more details.

That's great. And then just as a quick follow-up on the wire harness rollout. I think you mentioned last quarter that BLA 2.0 products were really complementary. So just curious if kind of the extension on first sales for wire harness -- the new wire harness product has any impact on BLA 2.0.

It really doesn't affect -- the wire management system is a subset of the bundle. And what's nice about our wire management system is it can be sold as a stand-alone or it can be sold as the bundled kit. So it gives us quite a bit of optionality in our deployments.

The next question comes from Brett Castelli of Morningstar.

I just want to ask about international here in 2023 and your thoughts on potentially expanding manufacturing -- your manufacturing abilities potentially abroad.

Yes. As I mentioned, the -- we're very excited about where we're at with international. We're getting increasing quoting volumes in Latin America, Australia and EMEA. And with that, we have to start looking at how we can best fulfill those orders and serve our customers. So part of the focus on growth, and as I mentioned in my remarks, our goal is to take us to the next $500 million. And that is by being able to fulfill orders where the customers are. So we are starting to take a look at that. And as you would expect, the pipeline is growing through the quotes. They'll then transition to awarded orders and backlog and then into revenue. So that all has to be timed appropriately. But just to reiterate, we're really excited about where we're at with international and the markets that I mentioned.

Okay. And then on the domestic solar side, can you just update us on your customer mix between -- I think, historically, it's been EPC heavy. Any headway you've been able to make with developers specifically?

Yes. Our primary customer base is the EPC domestically. We've got 9 of the top 10 EPCs that we're proud to call our customers and working on growing that as well. We are expanding our interface directly with developers. And one other trend that we're seeing as more and more EPCs want to lock up capacity is entering into long-term MSAs with them, gives us more certainty and order flow throughout the years.

That's great. Best of luck, Jason.

The next question comes from Colin Rusch of Oppenheimer.

Could you just give us a sense of 2 things, just the overall quotation activity outside the U.S. and then the close rates that you're looking at so far in the awards that have been made?

Yes. We haven't released the specific close rates, but what I did mention in the prepared remarks is that we're seeing quoting volumes of greater than 50% year-over-year. So the number of quotes and the volume related to those quotes continues to grow. Don't have specifics that we've released, and we have not released our close rates.

And then -- that's helpful. With these new customers that you've gotten, how many of those folks are moving into the EV space in terms of execution on that? So is there any crossover in terms of who you're selling to for that EV offering versus the renewables offering?

Yes. I appreciate that question, Colin. It's interesting. Most of the EPCs are exploring that as an option. But we're seeing in the eMobility market now that most of those decisions are being made directly by the charge point operators, and that's been our primary go-to-market focus in the EV space. As the EPCs then start to migrate over and expand their business into eMobility, then we'll be prepared there as well to call them our base accounts. We haven't seen as much crossover right now. They're focusing on growing the domestic solar market.

The next question comes from Brian Lee of Goldman Sachs.

Jason, best wishes. I'll echo others' sentiments as well, hope the best for you going forward. I guess I might have missed this, I jumped on a little late, but you guys last quarter broke out the backlog piece versus the awarded orders piece. It looks like in your K, you filed, you did break it out. So backlog grew modestly sequentially, and awarded orders also grew modestly. I guess I would have expected given the big jump in awarded orders last quarter relative to backlog that maybe some of that converted a bit more aggressively this quarter. So can you maybe just talk high level about what you're seeing with respect to traditional backlog conversion, if there is anything changing in the near to medium term? And is my presumption wrong that a big uptick in awarded orders should have translated into maybe a bigger uptick in the actual backlog a quarter following? And then I had some follow-ups.

Appreciate the question, Brian. And I've heard Jason say a number of times that backlog and awarded orders may go up or down quarter-to-quarter, but the trend continues to be up. And that's what we're seeing. We're seeing a timing of when the awarded orders come in. And what Dominic had mentioned is that we've seen a very robust first few weeks of January and through January and now into week 6. What I can attribute it to is -- looking back is timing. We're excited about where we're at this year and don't have any cautionary flags on our side about product adoption.

The only thing -- Brian, if I could just add...

Two other things I'd like to throw in there real quick. Dominic, and please jump in if I'm not adding exactly what you were going to. But one of the things that Dominic mentioned in his prepared remarks, Brian, you may have missed that, is that literally just a couple of weeks into the new year, we were already at record levels from backlog in awarded orders perspective. So obviously, a little bit of a time shift there, maybe some companies out there, partners out there took a little bit longer of a Christmas holiday. I'm not too sure. But the other thing I want to point out, obviously, is that we had yet again another record quarter, covering not only almost $100 million of revenue throughout that particular quarter as well. So very excited about where we ended the year and also even more excited about what transpired just a few weeks into the new year. Dominic, anything else you want to add there?

Yes, that was really it. The only other thing I was going to say is that in Q3, when we achieved the $470 million, there was a little bit of kind of some delays in the first half of the year. So we saw a run-up. So it is a little bit lumpy, but we're very pleased with the trajectory. And ultimately, we're very pleased to issue the guidance that we have today for the strong growth for 2023.

Okay. Great. That's super helpful. I guess we'll look forward to the Q1 number just given what you've seen in January. That's great. And then a question just on the model itself because -- and we've had discussions about this in the past. The revenue growth has been great for as long as we've covered you several years. And again, you're guiding to like 50% revenue growth. This would be like the second or third year in a row, though, where your revenue growth is basically matching your targeted EBITDA and earnings growth. I mean I think last year, revenue growth was a little bit faster than actually EPS and EBITDA growth. And you had talked about pulling in some investments for some of these new areas that you're targeting in the market. Any comments just around '23 operating leverage in the model and then where there might be some opportunities for you to eventually get to a point where you're starting to see more leverage, earnings or EBITDA growth well ahead of your good revenue growth?

Sure. So Brian, I guess, how good is good enough, right? So look, we do have some margin expansion baked in. If you just look at our midpoint of guidance, we have probably 150 basis points of margin expansion. And as I've stated before, our real objective right now is to continue to drive the top line growth, and we have some investments that we're going to continue to make. As I said in my prepared remarks, we still have to build out to be a large accelerated filer in the finance organization. We still have human resources capabilities that we're building to really become a scalable, much larger organization. We have customer care investments and sales investments that we're making to drive growth. So there's a number of things that I've guided to historically. I would say that we're looking to drive the top line. We are looking for margin expansion. There are many expenses in the SG&A space that will be leveraged. But fundamentally, I'm not looking to really drive margins to EBITDA margin of 40% in rapid fashion because I think we have too much opportunity to drive growth. So our guidance does incorporate margin expansion, and we're very pleased with that. And so there's a number of things that I think from opportunities in the future, there will be, but we're still at that point where we're trying to keep our eye on the prize. As Jeff mentioned, how do we get to that next $500 million? So that's really all. Until we have an Analyst Day and give multiyear guidance, that's the best I can tell you right now. I'm not looking to back up on margins. I'm always looking for modest expansion, but we have investments that we want to continue to make.

The next question comes from Jeff Osborne with Cowen and Company.

I just had 3 quick ones, so you can keep your answers brief, team, there. But on the international side, you alluded a couple of times to preparing for the next $500 million of growth. Can you talk about how long it would take to build a new facility and how much it would cost?

It takes from 6 months to 9 months typically, and that's on the lower end of the spectrum, to sign the lease and begin to outfit it. I won't specifically address cost. I'll let Dominic talk about that if he wishes to. But overall, the real question is what is going to be produced in that facility? If it is final assembly and test, it could be done faster.

Is it safe to say the CapEx guidance for the year does not include any new locations and that's more maintenance CapEx?

No, I would say the guidance that we've issued does include unproductive time and CapEx to pick up another facility, if we were going to go organically find a site, say, for sake of argument, in Texas or something. We haven't released and discussed where that may be, but the guidance does contemplate that we would have some perhaps unproductive time. The CapEx guidance also does include a step-up in capital, which would start being spent this year, to start outfitting the machinery and the racking necessary to get the facility production ready. So I would say that our guidance this year is all encompassing, with the exception of, obviously, it doesn't include anything if we're going to go and acquire a facility overseas or something, that's not in that number.

Got it. Helpful, Dominic. Just 2 other quick ones. On the market share, I know that final statistics from Wood Mackenzie aren't out. But I think you were 36% in '21. Do you have any back-of-the-envelope figures you could share for '22 or what your expectations would be?

Yes. Jeff, we use the Wood Mackenzie data for our market share calculations. As we -- if you recall, last year, those come out in second quarter, and we based our release based on that data. We expect the same to happen this year. So the '22 data, we're expecting to release after the Wood Mackenzie numbers come out midyear. I would say that based on our incremental EPC growth and the overall numbers, we do expect some good news on the share gain side.

It would seem so. Just another question, following up on Brian's comments about margin. So you guided to 40-ish percent gross margin. You obviously had very strong results here in 4Q. I'm trying to understand, with all the new products that you have launching and assuming battery and EV grow as well, maybe faster than they did last year, are the newer things maybe dilutive to gross margins or at least what you just printed in Q4 and accretive on the EBITDA side? Is that the right way to think about it? Or is the in and around 40% target more -- a bigger range around that in terms of multiple hundreds of basis points of potential upside or downside depending on mix.

Yes. We haven't released product line margins. There's just a couple of things I think generically, I'd want to say there. One is I just mentioned the fact that we may be getting some additional unproductive capacity this year. And that would be a drag on COGS. Anything you launched in the facility, you have to incur the expenses as they're incurred, you recognize them as incurred. So there could be some additional investments there. As we evaluate the labor markets and our utilization of labor, hourly wage labor, we want to stay competitive. We obviously are growing. We want to be able to get the talent that we need. So there may be some investments that we're doing there. There are some things that we've done from health insurance to become more competitive. So in the grand scheme of things, the 40% range is what new products, that's kind of the minimum that we look for. Some of our product lines are higher than that, and there are some things that are lower. But we want to make sure that we're always targeting around that 40% mark, if that makes sense to you.

The next question comes from Martin Malloy of Johnson Rice.

I was hoping maybe you could refresh us in terms of capital allocation. You're all obviously going to be generating a lot of free cash flow here.

Sure. So our first priority, as we look at capital allocation, is we have -- we still have at the end of the year, I believe, $48 million of revolver left. And with interest rates climbing, we are looking at what that would look like for us. We are generating some cash. There are opportunities that we'll be discussing with our Board about the best utilization of that cash as we generate it. It's a great problem to have. I'm thrilled that we're going to be in that position. The term loan did have a prepayment associated with it -- a penalty associated with it that does expire this year. So there's always the opportunity to do some things there as well. But our leverage ratio is really improving over time as well. So I'm looking for ways to drive additional growth in the business. And -- go ahead.

No, I'm sorry, go ahead.

I was just going to say as we have discussions about the best use of that cash flow, we'll let you know. But at this point in time, we're just pleased to have that in our guidance.

The next question comes from Kashy Harrison of Piper Sandler.

I was wondering if you could just provide us with an update on the progress with the EV charging business. Can you speak to receptiveness from the market? And then maybe some color on how much of the 2023 revenues is associated with the EV charging business.

Thank you for asking. The adoption has been strong. Our primary market segments are fleet and school bus electrification. We're seeing a definite uptick in the National Electric Vehicle Infrastructure funds coming from the infrastructure bill. That would be for corridor fast charging. And the quoting volume there has greatly increased. We haven't released specific financials yet because we're waiting for them to be substantial and predictable before we do that. But overall, I'm excited to say that we're deployed in more than 15 states in the U.S. with large numbers of projects. So overall, customer demand is exceeding expectations, and we're seeing continued growth.

Thanks for the color there, Jeff. And then maybe a follow-up to Martin's earlier question. Dom, can you speak to your expectations on working capital for 2023? Just looking at '21, it looks like $34 million use of cash, '22, $38 million use of cash. So just any sort of color on how to think about working capital for '23 would be great.

Sure. So one of the things that I've said, and I said last quarter for sure, was that we had an opportunity to optimize some of these things. And I think you saw some progress made in Q4 as we started -- in fact, inventories did come back down from their peaks from earlier in the year. We've made a huge dent in the receivables, and we've implemented new things. We've also shared talking about some of our customer deposits. So we believe working capital, yes, there's always investments when you're a growth company, when you're going from $300 million to, call it, $490 million, $500 million, whatever, in our guidance range there. There's going to be investments required for working capital. But I believe that we have seen the worst of our inefficiencies. We'll continue to manage inventories effectively with the sales growth. We'll continue to manage our DPO as we changed some vendor agreements that we've also talked about last quarter. So I would say they'll be modest. I think if you look at your models from a DSO, DPO, inventory turns, you should see some modest improvement in all those categories in '23 versus '22.

The next question comes from Donovan Schafer of Northland Capital Markets.

First, I want to ask -- so I think it was on the third quarter call when you guys reported some demonstrable success on the EV side, but I believe you also said at that point in time, you did not have the drive over raceway available yet or sort of fully certified and so on. So I guess my question would be is the drive over raceway now available? And if not, when do you expect that to be available?

Thanks, Donovan. The drive over raceway is certified the UL standards and available and being quoted. In fact, I believe there's product shipping this quarter. So excited about that one.

Thank you. This concludes the question-and-answer session and today's conference call. You may disconnect your lines. Thank you for participating, and have a pleasant day.

Thanks, everybody.
