Good afternoon and welcome to the Shoals Technologies Group fourth quarter 2020 earnings conference call. Today's call is being recorded and we have allocated one hour for prepared remarks and Q&A. At this time, I would like to turn the conference over to Ms. Megan Peek, General Counsel for Shoals Technologies Group. Thank you. You may begin.
Megan Peek
Thank you, Operator, and thank you, everyone, for joining us today. Hosting the call today are Shultz Chairman Brad Forth, CEO Jason Whitaker, and CFO Philip Garton. On this call, management will be making statements based on current expectations and assumptions, which are subject to risks and uncertainties. Actual results could differ materially from our forward-looking statements if any of our key assumptions are incorrect because of other factors discussed in today's earnings news release. and the comments made during this conference call or in our latest reports and filings with the Securities and Exchange Commission, each of which can be found on our website, www.scholes.com. We 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 Brad.
Brad Forth
Thank you very much, Megan, and good afternoon, everyone. This is our first conference call since completing our initial public offering in January. I would like to start out by thanking our team for their outstanding execution, as well as our new shareholders for their tremendous support. The IPO was an important milestone for our company, and we are all excited about the new opportunities that being public creates for us. 2020 was a year of record revenues, margins, and profits for Shoals, and I think Jason and his team are just getting started on what they can achieve. I'll now turn it over to Jason to provide an update on our business performance and strategy.
Megan
Thanks, Brad. I'm going to focus my remarks today on four topics. How we performed against our KPIs in 2020, the outlook for our end markets in 2021, progress we've made on our growth strategy, and actions we've taken to further strengthen the depth capabilities, and commitment of our leadership team. Following that, I'll turn it over to Shoal's Chief Financial Officer, Phil Garden, who will provide financial highlights from the fourth quarter and full year of 2020, as well as our 2021 financial outlook. So starting with our performance against our KPIs. Those of you who met us during our IPO Roadshow know we have two primary financial objectives. grow our top line faster than the market, and maintain or expand our adjusted EBITDA margins. We achieved the former by taking share and entering new product categories, and the latter by increasing the contribution of higher margin system solutions to our total revenues. We grew our total revenues and system solution revenues 21% and 57% respectively in 2020. Our system solution revenues grew faster than the overall EVOS market as a result of share gains. In 2020, we believe approximately 50% of the solar energy projects installed in the US use at least one Shell's product, an increase of more than 10 percentage points versus the prior year. In 2020, we generated 66% of our revenues from the sale of system solutions. an increase of approximately 15 percentage points versus the prior year. The increase in the percentage of our revenues from system solutions contributed to an expansion of our adjusted EBITDA margins of more than 900 basis points from 25.5% in 2019 to 34.7% in 2020. Now turning to the outlook for our end markets. In our core U.S. solar business, we're seeing increasing levels of demand as the build-out of new projects accelerates. The acceleration is being driven by growing corporate and utility commitments to buy more of their energy from renewable resources, as well as the normalization of permitting processes as more states reopen from the pandemic. The two-year extension of the solar ITC in December has also expanded the total number of projects that are viable. though it may lead to some projects being started later in the year than originally planned, as developers have a longer window to commence construction. To put the market momentum we're seeing in context, our quoting activity in the first two months of this year has increased approximately 50% year over year. It's also important to highlight that the acceleration in the solar market does more than just increase our addressable markets. It also pushes customers to adopt our solution versus conventional EVOS. The reason for that is as activity levels grow, labor rates rise and labor availability falls. Many of our EPC customers are telling us that they're having difficulty staffing jobs. The opportunity right now is that big because our combined ego system installs much faster than the conventional EVOS and does not require skilled labor. We can be the difference between our customers being able to take on an incremental job versus letting it go to a competitor because they simply don't have the crews available to do the work. Longer term, we're even more bullish about solar than we were a few months ago. The Department of Energy's estimate for the LCOE of utility-scale solar coming online in 24 months has improved 17%. from where it was just a year ago, reflecting solar's continued march down the cost curve. And we've noted that based on declining cost, one of the major solar industry analysts that we follow has increased their forecast for new installations by more than 20% for the next three years from what they were forecasting in just June. That's a huge increase in the size of the market and aligned to what we've been seeing in the marketplace and hearing from customers. And I'll now spend a couple of minutes on our growth strategy and the progress we've made on each element since our IPO. There are five elements to our growth strategy. Growing market share by converting more customers to our combined as you go BLA solution. Selling more product to our customers by focusing on projects that incorporate energy storage. Growing our wallet share with customers by introducing complimentary products that address other EVOS categories. expanding internationally, and introducing new products for EV charging infrastructure. I'm excited to report that we're on or ahead of plan for each of these initiatives. First, our combined as you go system continues to take share from conventional home run solutions. Late in the fourth quarter, we converted an additional EPC to our system. That EPC has entered into an MSA with us that's already resulted in approximately 320 megawatts of orders for this year. We're targeting converting additional EPCs to our system in 2021 as we work to increase our market share to our 60% target. Second, our strategy of concentrating on projects with energy storage is beginning to pay early dividends. Projects with storage spend about 55% more on EBOS than projects with just solar. More and more of our project pipeline includes storage, which we expect to lead to higher shows revenues on each project we ship. Third, our strategy to introduce new products in the EBOS segments where we did not historically play is on track. Last week, we installed pre-production versions of our basic IV curve benchmarking solution across two different projects. The customers reported that the installations went flawlessly, and the project owners are already seeing benefits from the granular performance data that the products provide. Next quarter, selected customers will begin installing pre-production versions of our wire management solutions. Those installs will start as soon as our patent dockets issue. We're working on improved versions of our existing products and are currently in the process of filing seven new patent applications, both in the U.S. and internationally. Fourth, we've continued to make progress on our international expansion strategy. We've recently hired a new VP of EMEA Sales to lead our international expansion in that region. and we're already in conversations with five potential new European customers. Fifth, we're focused on developing products for EV charging infrastructure, where the same issues of insulation inefficiencies and labor availability make building stations more expensive and time-consuming than what they need to be. We see shortcomings in the products currently available in the market that create an opportunity for disruption. With Ford, GM, and other OEMs recently announcing plans to phase out ICE vehicles, we're moving towards an EV world even faster than what was projected six months ago. Considering that, we've taken steps to accelerate the development of our EV infrastructure business, which we believe could become an entirely new leg to our business. We recently hired Jeff Tolnar to be our Senior Vice President of EV for our organization. Jeff previously served as the Chief Commercial Officer of Green Lines, a leading provider of turnkey EV charging solutions that was acquired by Shell. We're confident that Jeff and his team will help Shell disrupt the EV charging space the way we've disrupted solar EVOS. Lastly, I wanted to cover a couple of things we've done since our IPO to further strengthen the depth, capabilities, and commitment of our leadership teams. First, we'll be announcing shortly the appointment of three new independent directors to our board, bringing the total to four independents. Each of these new independent directors are established business leaders who bring new capabilities to our board, including international business experience. Second, we further strengthened our U.S. sales and marketing team by hiring the former director of marketing for Canadian Solar and a North American vice president of sales who previously held similar roles for Delta and Huawei. Third, we made all of our employees shareholders in connection with our IPO. We believe that aligning every member of our team with our shareholders is important. And as you can tell, we've been busy since our IPO. Solar's growing rapidly, our products are winning in the marketplace, and we're executing well against the growth plans we've laid out in our IPO Roadshow. I could not be more optimistic about our potential this year and beyond. With that, I'll turn it over to Phil for an update on Shoal's financial results and outlook.
Brad
Thank you, Jason. I will provide some commentary on our fourth quarter and full year 2020 results, followed by our 2021 outlook. For the fourth quarter, we generated revenues of $38.8 million, which was in line with our expectations. Year-over-year growth was more modest in the fourth quarter due to extended downtime we took in December, but we expanded capacity, as well as an extraordinarily strong Q4 2019. We expect quarterly comparisons going forward to be consistent with year-over-year growth implied by our guidance, although we expect more of our growth to come in the second half versus the first half. Prices across our product lines during the fourth quarter were comparable to the prior year. Gross margins in the fourth quarter increased by more than 530 basis points to 38.3%, from the prior year period as a result of a higher proportion of revenue from combine-as-you-go system solutions, purchasing efficiencies from increased volumes, improved material planning which reduced logistics costs, enhancements to product design that lowered manufacturing costs, and other manufacturing efficiencies resulting from higher production volumes. Operating expenses were $7.7 million compared to $4.3 million in the prior period. This was driven by higher equity-based compensation, increased payroll expense due to higher headcount, and non-recurring expenses related to our IPO. Adjected EBITDA, which excludes amortization of intangibles, stock-based compensation, COVID-19-related expenses, and other non-recurring items, was $14.1 million, up 32% from $10.7 million in the prior period. with adjusted EBITDA margin increasing approximately 820 basis points year over year to 36.4%. Adjusted net income increased 10.6% to $11.1 million compared to 10.1 million during the same period in the prior year. Now turning to our full year results. Revenues for the year ended December 31, 2020, from 21.5% to $175.5 million, compared to $144.5 million in the prior year. This was driven by significantly higher sales volumes as a result of increased demand for solar EVOS generally and our Combine As You Go products specifically. We derived 66% of our revenues in 2020 from sales of system solutions, which was an increase of approximately 15 percentage points versus 2019. Gross profit increased 50.5% to $66.5 million compared to $44.2 million in the prior year. This was driven by higher volume and efficiency gains. Gross margin expanded by approximately 700 basis points to 37.9% in 2020, compared to 30.6% in the prior year period. Higher gross margin was a result of having more revenues to absorb fixed costs, as well as increased sales of system solutions for combined-as-you-go EBOS, which carry higher margins than our other products. Operating expenses were $29.3 million compared to $17.3 million in the prior year. This was primarily as a result of higher non-cash equity-based compensation related to our Class C units issued, an increase in headcount, and professional fees related to our IPO. Adjusted EBITDA grew 65.6% to $60.9 million compared to $36.8 million in the prior year. Adjusted net income increased 66.4% to $56.3 million compared to $33.9 million in the prior year. Adjusted EBITDA and adjusted net income exclude amortization of intangibles, stock-based compensation, COVID-19-related expenses, and non-recurring items. Please see the adjusted EBITDA and adjusted net income tables in our fourth quarter press release. Turning to our outlook for 2021, our backlog as of December 31st, 2020, was 157 million, representing an increase of 46% yearly year. We have also seen our backlog continue to grow during the first quarter as a result of robust order activity. Based upon what we are seeing in the market and feedback from our customers, we currently expect 2021 revenues to be in the range of 230 to 240 million, representing a 34% year-over-year increase based on the midpoint of the range. We expect adjusted EBITDA to be in the range of $75 to $80 million and adjusted net income to be in the range of $47 to $51 million. Now I will turn it back over to Jason for closing remarks.
Megan
Thanks, Phil. I'd like to wrap up with five simple reasons why we're excited about Shoals for 2021 and beyond. Number one, growth in our core U.S. solar market is accelerating. Number two, we have the category-killing product for solar EVOS, and we're taking share. Number three, we continue to migrate customers from components to system solutions, which allows us to earn higher margins. Number four, We're on our way to tapping the international market opportunity, which could ultimately be as large as our core U.S. market. And number five, we see an opportunity to bring innovation to the EV charging, which could create an entirely new leg for our business. Thank you for your time today. Now we'll open up the line for questions.

At this time, we will be conducting a question and answer session. If you would like to ask a question, please press star 1 on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star 2 if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary for you to pick up your handset before pressing the star keys. Please limit yourself to one question and one follow-up. One moment while we poll for questions. Our first question comes from the line of Brian Lee with Goldman Sachs. You may proceed with your question.
Brian Lee
Hey, guys, thanks for taking the questions. Congrats on the first quarter here out as a public company. Good job. Maybe just first question, Jason and Phil. The backlog is up 46% as of the end of 2020, so you've got a lot of momentum heading into the new year. The revenue guidance, I know you're saying it's based on what you're hearing from the customers and the visibility you have, but it's up, you know, 30%, 35% year on year. backlog, as I recall, is a 12-month number. So is the revenue outlook just a little bit conservative relative to the backlog growth, or is the backlog just kind of a lot of first-half visibility, and so you don't want to stretch into kind of the back half and what kind of business trends you might see there? And then I have a follow-up.
Megan
Perfect. Hey, Brian, this is Jason. Good talking to you again, and thank you very much. You know, I guess, first of all, we take meeting the commitments we make to our shareholders very serious. And for that reason, we're very confident in the guidance we provided today. But keep in mind, to the extent that we do see our performance meaningfully exceeding our guidance, we would definitely update you in subsequent quarters coming down the pipe.
Brian Lee
All right, fair enough. But just to maybe provide a little bit of context, the backlog is a 12-month number, and, you know, would you say there's, you know, any kind of notable timing cadences to first half, second half embedded in that backlog?
Megan
So, you know, the backlog is, you know, a large portion of the backlog is a 12-month number. I mean, as we've talked about You know, before we do see, you know, even further visibility past that, but a significant portion of that backlog is in the first, you know, first 12 months with a large portion of that actually rolling into Q3, Q4 as we see it today.
Brian Lee
Okay, great. That's helpful. And then just my follow-up is on some of the commentary around the EPCs and conversion. So it sounds like you've already done a conversion here early on in the new year, and you've got several more on the way. Can you provide a bit of context as to – You know, are these all kind of larger top 10 EPCs? I know you had several of them at the time of IPO. But are these the rest of the top 10 you hadn't yet converted? And is there sort of a target for, you know, them becoming kind of 50%? You becoming 50% of their book this year and moving higher? Or kind of what's the cadence for penetrating some of the new accounts as you do convert them over? Thanks, guys.
Megan
No, perfect. Thanks, Ron. Good question. So, you know, the EPC that we mentioned in our prepared remarks, that is, you know, definitely a top player in the market. And from a timing standpoint, you know, it's really difficult to say. I can tell you that I'm very proud of, you know, how the Excel team has operated and and what they've been able to accomplish from that perspective. But just considering that the time period in which we start working with those EPCs, that conversion cycle may vary coming down the clock. So we are going after several more top EPCs that are in the market to be able to get us to our set goal that we're going for.
Brian Lee
Okay.
Megan
Thanks a lot, guys. Thank you very much, Brian.
Operator
Our next question comes from the line of Char Peruzza with Guggenheim Partners. You may proceed with your question.
Cody
Hey, guys. How's it going? It's actually Cody Clark on for Char. Thanks for taking my questions. So first, can you provide any updated color on the progress with BLA 2.0? Are you still on track to complete product engineering by 2Q this year? And then when should we expect more detail on the product and its implications on your growth trajectory? Is it kind of after that product engineering phase or is it after the validation and certification phase?
Megan
Hey, Cody, this is Jason speaking. So, you know, as we've talked about in the past, I'll just, you know, cover a few of those topics. We can't go into a lot of detail about BLA 2.0, you know, because we haven't completed that full patent cycle. But, again, how I would think about the product is that it offers an additional level of savings from an installation cost perspective based upon the labor savings that it provides above and beyond what the current BLA brings to the market today. And when we look at the BLA 2.0, it does that by essentially incorporating other components that we don't currently provide or participate in today. And when you look at really where we are, I'm excited to say we're on track with that product as well, just like we are with all of our other products that we've mentioned about bringing to market. But just to reiterate what that is, we will be going through and doing a commercial launch early next year and expect to be generating revenue towards the latter half of 2022. And then once we complete the patent docket for that particular product itself, and we go through our what I would call pre-production process with our customer base, that's when we will open up that particular technology for further information.
Cody
Got it. Okay, that's helpful. And then second, just on the rip and replace opportunity, you know, you mentioned previously that you're starting to see some RFPs for these types of projects. Wondering if that's picked up at all in the past few months. And is there any data points that you can kind of point to that would help us frame this opportunity in 2021 and beyond?
Megan
So the short answer is, you know, we have seen an increase in rip and replace opportunities. I guess since the last time we spoke, we've actually quoted quite a few projects, to be honest. But when you look at forward-looking guidance, it's very difficult to be able to predict exactly what that is because it depends upon what the failure mode is. If it's something that's impeding performance and it's not a safety issue, it's really based upon the frequency in which that particular client wants to go through and replace that product. They may just replace it as it fails. But if it's a significant safety issue, then, you know, they're pretty much obligated to go through and replace that product with something that works. So it's very difficult to be able to provide, you know, forward guidance from a rip and replace perspective.
Cody
Awesome. Thanks so much, and congrats on the execution.
Megan
Absolutely. Thanks, Cody.
Operator
Our next question comes from the line of Michael Weinstein with Credit Suisse. You may proceed with your question.
Michael Weinstein
Hi, guys. Thanks for the question. Hey, on international shipping delays we're seeing in some of the ports, I'm just wondering is that impacting you at all? I know a lot of your parts are made domestically, but is it impacting perhaps maybe your overseas expansion in any way?
Megan
Yeah, so that's a good question, Michael. So, yeah, we are seeing, much like I would assume everybody else is, You know, we are seeing shipping delays. But one of the things that you'll find is, you know, we're very conservative, you know, both on inbound and outbound. Not very much of our product is inbound, but specifically outbound. So we try to make sure that we don't miss any particular customer delays. And for that reason, we've been very successful in executing against the commitments that we made to our customers and, as a result, have not had any shortcomings from a delivery perspective right now.
Michael Weinstein
great and um uh also the uh are you seeing any impact at all from higher commodity costs copper aluminum and the like yeah hey phil uh yeah sure yeah i got that one uh prices of copper and aluminum wire have increased but they are not impacting our margins
Brad
As you know, the reason is that our wire suppliers commit to a price that we quote in a system, and that our customer only has seven days to accept that quote, and that's when they can issue a PO. If they wait more than the seven days, we will refresh the quote, and that will be reflected in the new price that they're quoted. So we pass through all commodity risks onto our customers, and – They understand it, and we understand it. So it works quite well.
Michael Weinstein
Got it. You're still a relatively small part of the overall cost of construction, so it's not – Oh, yes. You don't see it impacting sales really that much probably, right?
Brad
No, it hasn't moved a needle yet on demand for the product, for the overall product.
Michael Weinstein
Just in terms of – oh, go ahead.
Megan
Go ahead. Just one other thing. I mean, when you look at the increase, right, that's – you know, you're asking about, uh, in terms of sales, I mean, you know, we're seeing an increase, you know, all of our competition seeing an increase as well. So, uh, but yeah, we've not seen any, any decrease in sales because of it. Good question.
Michael Weinstein
Gotcha. Um, what about the revenue mix in 2021, uh, you know, versus us versus international storage, EV charging, uh, congratulations to, uh, Jeff, uh, on heading the new EV infrastructure business. And also just in terms of EV, um, yeah, since, since, uh, You last spoke about it. I mean, are you seeing any more total addressable market there or any more opportunities beyond the $30 million opportunity that you previously talked about there?
Megan
So, you know, as far as, you know, forward guidance, you know, breaking it down between, you know, the different opportunities and the different segments, that's something that we're not doing, you know, as of right now. But, yes, we're very excited about EV, very excited about, you know, bringing Jeff online. There's a lot of things that we see. You know, we've talked about in the past, you know, the EV market is much like what the solar market was to us, you know, many, many, many years ago. We see a lot of opportunities for optimization just based upon, you know, products that don't really exist out there in the market today. So, you know, we're very excited about that, but we're, you know, we're still, you know, tracking towards the commitment that we made to the public market.
Operator
As a reminder, please limit yourself to one question and one follow-up. Our next question comes from the line of Paul Koster with J.P. Morgan. You may proceed with your question.
Paul Koster
Yeah, thanks for taking my question, and welcome to the public markets. So just focusing on the international growth and the EV growth opportunities for a moment, can you talk a little bit about your go-to-market strategies for both and how they're evolving? It sounded like in the international zone you're hiring a marketing professional. Previously, I thought you'd be following your customers into those markets, so perhaps you can elaborate on that. And Jason, it did sound like you were incrementally constructive about EV charging. and you must have some visibility into, you know, how you're going to get to market with it, because it's a much more fragmented end market, right?
Megan
Yeah, hey, Paul, Jason here. So, you know, looking at the international market, you know, we have the hire that we have made there is we've hired our VP of EMEA, you know, so boots on the ground, you know, local representation. We're very excited about that hire. And when you look at the strategy in general, you know, we're really, as we've talked about in the past, is, you know, taking a two-prong approach that we found to be very successful in North America, you know, by working with, you know, not only the local EPCs but also the you know, the owners and the developers to make sure that they really understand that value proposition and push that product through into the EPCs that they work with. So, again, very similar approach to what we've done very successfully in North America. You know, and as I mentioned, you know, we're already working with, you know, several new clients internationally and, you know, working on the project that they have in their pipeline so that we can start, you know, converting them over to the Shoals product suite. and your second part of the question paul uh and let me know if i missed something else you know when you look at when you look at ev you know as we talked about uh you know in the past you know the the products that we're going after you know are predominantly you know on the e-boss side uh that allow you to go through and optimize you know the e-boss portion you know of that ev market and you know ironically you know because of that several of the customers that you know we already serve and serve well you know, in the space of, you know, specifically renewables already play in that market. So, you know, we're going to take a very similar approach at EV by going after the, you know, the larger installers. And again, you know, we're looking at, you know, fleet level applications. So we're not really targeting what would be quantified as like a residential cell, which is very fragmented, as you mentioned, Paul.
Paul Koster
Okay, got it. All right, one last question. You said that the quoting activity was up, I think, 50% year-on-year or something of that nature. What is quoting activity? Perhaps you can just sort of define it for us a bit. Is it the dollar value or the number of calls, for instance?
Megan
Yeah, that's actually a great question, Paul. You know, that particular metric, I believe, was the quoting activity itself. You know, as quantified by, you know, the number of quotes that go out from the sales team. But, you know, how I would think of that is, you know, when you look at the market that we're in, you know, a lot of the projects that are going out are very, you know, very large projects. So a significant increase in what we've seen year over year and very excited about, you know, the opportunity ahead.
Paul Koster
Okay, thanks.
Megan
Thanks, Paul.
Operator
As a reminder, if you would like to ask a question, please press star 1 on your telephone keypad. One moment while we poll for questions. Our next question comes from the line of Steven Beard with Morgan Stanley. You may proceed with your question.
Steven Beard
Hey, good afternoon. Congrats on a good start to being a public company. Thank you very much. I wanted to just explore the EV business a little bit more. It sounds like you're very optimistic there. Is this something where we could see some relatively important announcements sometime this year? Do you think it's sort of more likely to just see incremental activity without any sort of major sort of milestone changes? agreements, or is it more likely to be, I guess, chunky to use a non-scientific term, but just sort of how should we kind of think about the evolution of that opportunity in 2021?
Megan
So, you know, what I would think of EV in terms of 2021 is, you know, really, you know, we're building out what I would call an EV infrastructure business unit, and we're doing that you know, again, based upon, you know, the rapid acceleration that we see in the EV market. So, you know, we're going to be going through validating some of the products, you know, that we've already identified, and then, you know, further finalizing our product roadmap so that, you know, we can roll out a very successful product based upon feedback from, you know, the customers that we already know that participate in that market. And, you know, as that particular product product opportunity begins to flourish, we'll definitely communicate about more of our plans in the upcoming quarters.
Steven Beard
Understood. So it does sound like maybe one of the more notable things would just be sort of major product announcements that you think sort of address a critical need there, right? That could be some of the more noteworthy things we see.
Megan
Yeah, that's what, you know, that's something that, you know, you could definitely, you know, consider, you know, going forward would be just, you know, general, you know, products that we're bringing out, you know, announcements and exactly what they do, yes.
Steven Beard
Okay, great. And then just one other on geographic growth, a number of questions on that already, but given the nature of your hire, I thought I'd just check in since the time of your IPO in terms of areas of geographic areas that look most promising to you. It sounds like, you know, you're Europe continues to be a key area. Are there any other geographies sort of noteworthy that we should be thinking about?
Megan
So obviously you're spot on with Europe in that general region. That was one of the reasons why we went after bringing on our first candidate in that area, but also LATAM. We're still seeing a lot of opportunity in Australia. So really, without going into a lot of detail, a lot of the opportunities that we originally laid out we are seeing still exist today.
Philip
but you know i definitely would say that europe is a very strong area you know as we speak right now perfect thank you very much our next question comes from the line of philip shen the cloth capital partners you may proceed with your question hey guys thanks for taking my questions uh first one has to do with um revenue mix uh as we get through um the quarters I think Philly talked about more revenues in the back half versus the first half. Can you talk about or quantify in any way what that might mean? And if there's any way you can even provide a quarterly sense, that'd be very helpful. Thanks.
Brad
Okay, so this is Philip. We don't give those forecasts by quarter, but as I mentioned earlier, there is a significant step up, even though we see a very strong first half with, as I mentioned, strong growth year over year, as we've seen the last several quarters, last couple of years, that historic growth. We're going to see that in the, we see that in the first part of the year, but then a major step up in the second half, a lot of projects are coming on.
Philip
Okay. So would a 70, 30, maybe 75, uh maybe 65 35 split work uh between back half and first half uh jason do you want to come i'm not sure exactly how much i can say honestly sorry in our first call but it will definitely be weighted towards the second half okay great and then maybe um talk through the margin cadence uh by quarter as well if possible Do we see improvement as we go through the year? Is it flattish and steady at this high 30s level percentage?
Brad
Well, the EBITDA margins, there's a variety of margins. But if you look at adjusted EBITDA margins, we will see it lower in the first part of the year and actually lower for the year than it was prior year. And if you remember, as we talked about during the IPO, It's primarily driven by investment in our SG&A, which is driven by, too, the public company costs, as well as, of course, equity-based compensation and those type of things. And we're investing in all of those growth initiatives. So there will be a step function in 2021 in SG&A. which is what we're looking at and we talked about before. But then the margins, the gross margins on our top line, we'll see we're projecting to continue to improve as we go through the year.
Philip
Okay. So we got roughly high 38.3% in Q4. Should we see that steady in Q1 and Q2 and then maybe a slight pickup in Q3 and Q4? I would
Brad
Don't go into details, but they will be an impact of SG&A as we go into this year, that it will take a step down. We're projecting that.
Philip
Yeah, I was talking about gross margins.
Brad
Sorry, Philip. Oh, gross margins. I'm sorry. Gross margins we see to continue to do very well and improve as we see that market shift to higher margin products to our system solutions.
Philip
Okay, one last one, if I may, around capacity. From your perspective, you guys talked about being at 1.8 times or having 1.8 times capacity of your trailing 12-month revenues as of the end of Q3, which were about $175 million. So if you just simply apply that 1.8 times, it suggests that you could be at $315 million in terms of a run rate of revenue versus your 2021 guide of $235 million. Can you just talk about what would it take to get to that higher level of revenue, what's limiting you now, and what might open that up? Thanks.
Megan
So, you know, Phil, that's a good question, and a pleasure speaking with you again. So, you know, yes, you are correct, you know, as far as the capacity we have. And, again, as we've talked about in the past, You know, we try to be very aggressive, you know, when it comes to, you know, having capacity available. You know, it's not uncommon for, you know, some of that customized manufacturing equipment that, you know, we design and build ourself for it to be built, you know, a year plus in advance. You know, matter of fact, you know, we're installing, you know, a significant amount of equipment that I highly doubt will be touched this particular calendar year. So that's one of the things that we always try to stay ahead of to make sure that we have that capacity available for opportunities when they come at you that you can actually capitalize on. So very important to our growth down the road. And when you look at the last half of your question, Phil, you know uh taking a and maybe i may have misunderstood this but you know essentially taking a spike up to uh you know 350 or or the like you know really you know we want to make sure that you know even though we do have a lot of opportunities ahead and some very exciting growth um you know we also want to do that very conservative conservatively and make sure uh that we can meet you know all the demands of our customers because you can have the best product out there in the world and if you can't meet the demands your customers need, then you're not going to be successful. So it's really a combination of the two, Phil.
Philip
Thanks, Jason. I appreciate all the answers to my detailed questions, and congrats as well on a successful IPO. Absolutely. Thank you very much, Phil.

Our next question comes from the line of Colin Rush with Oppenheimer. You may proceed with your question.
Colin Rush
Thanks so much, guys. Can you give a sense of how much of the revenue growth from 2020 to 2021 is being driven by higher commodity prices?
Brad
We actually don't have anything built in our model for growth about higher commodity prices because we do pass those on. So we have put nothing in our model of tweaking that up for commodity prices.
Colin Rush
Okay, that's super helpful. And then can you speak to any acceleration in close rates or the trend lines in terms of how much of the business you're quoting you're actually ultimately winning over the last couple of quarters?
Megan
Yeah, that's one of the things that we're not prepared to talk about today. But again, what I can say is that You know, the quotes that are going out and the phenomenal job that our sales organization is doing is nothing short of amazing. So very excited about the rate of closure on those projects.
Colin Rush
Okay. Thanks a lot, guys.
Operator
Our next question comes from the line of Ben Callow with Baird. You may proceed with your question.
Ben Callow
Hey, y'all. Thanks for the question. So two questions. So all the solar calls we've been listening to are talking about accelerating growth. And so I'd just like maybe y'all's perspective on that. And then, too, I grew up in Huntsville, kind of close to you guys. And, you know, there's a political sense about, like, solar panels and wind turbines and being not good in some areas. And I just wanted to hear y'all's perspective on how you guys deal with the political part of all this. Thanks.
Megan
Yeah. Hey, Ben, this is Jason here. So I'll take the first part of the question and maybe turn the second question over to Brad if he wants to comment, or I can proceed with it as well. But when you look at the first question from a growth perspective, You know, we are seeing a lot of opportunity ahead. You know, as we talked about before and mentioned in the prepared remarks, you know, a 50% increase in our quote profile from the sales organization is a very significant increase. So we're seeing a lot of opportunities. You know, when you look at some of those projects, You know, we feel like some of that quoting that's coming in is, you know, maybe from projects that, you know, that otherwise may not have been, you know, able to be constructed until, you know, the ITC, you know, took place. But, yeah, we're definitely seeing a lot of opportunities in growth, you know, projects that are coming online, you know, quicker or projects that we hadn't heard of as well as, you know, opportunities, you know, carrying out towards the latter year and on into 2022 and 2023. I'm happy to speak a little bit to, you know, the political question.
Brad Forth
Look, I think you go back a decade or so ago, and solar was not competitive with alternative sources of generation, absent subsidies. So political constituencies that are opposed to sort of meddling in free markets and that sort of thing, obviously weren't too happy about that. But that was then, this is now. Solar is full stop, levelized cost of energy of any form of production, I think the technology at this point speaks for itself. And I do think that political opposition wanes and is waning over time as a result of that. And it is a very robust, reliable technology. It doesn't have NIMBY problems. When you build it the way that many other technologies have, it actually performed well in the ERCOT region, by the way, during the big problems that occurred there. I think it was the one source of generation that exceeded expectations, unlike both gas and wind. We feel we're really on the right side of the equation here, and hopefully any resistance over time evaporates just because of the economic merits that solar provides. Thank you. You're welcome.
