Lastly, we will be referencing our earnings presentation today, which you can find posted on our IR website.
With that, let me turn the call over to George.
Thanks, Tim. Good afternoon, everyone. Thank you for joining us on our first earnings call. It's great to talk to all of you again, now as a public company. ACV's IPO was a significant step in our journey to build the most trusted and efficient digital marketplace for used vehicles. We accomplished this through a lot of hard work by many people. I want to thank my ACV teammates for achieving this milestone. We are very proud of how far we've come since ACV was launched in 2015, and we look forward to building on our success in the years ahead. For our call today, let me begin by providing some context on the ACV story by briefly recapping our 2020 results, then touch on first quarter highlights, and finally, discuss our strategy to deliver long-term shareholder value.
In 2020, we transacted over $3 billion of GMV and nearly 400,000 vehicles on our digital marketplace. This produced over $200 million in revenue, a 95% year-over-year growth. As you can see, our momentum continued in the first quarter of 2021, where we transacted over $1.3 billion of GMV and nearly 130,000 vehicles on our digital marketplace. We delivered strong revenue of $69 million, which generated 64% year-over-year growth.
Our performance in the quarter was driven by continued adoption of our platform as we attracted new dealers into our ecosystem and gained wallet share within our existing dealership customers. We also saw continued adoption of our suite of solutions that further enable a seamless experience for our dealers. Similar to other companies in the used vehicle sector, we benefited from favorable market conditions, which drove strong customer engagement on our marketplace and favorable unit pricing.
We have been able to drive significant growth despite the supply headwind that our franchise dealers face selling fewer new vehicles and having less used vehicle supply. Turning now to our strategy to drive long-term shareholder value, let me frame this by focusing on the three top- level elements of our strategy. Marketplace growth, TAM and product expansion, and operating scale. Marketplace growth is all about leading the digital transformation of the dealer wholesale market with our robust data-driven platform. We serve a large and complex addressable market. As Bill will discuss later, we are ramping our investments to continue capturing market share and further differentiating our digital platform. Next, we're expanding our total addressable market and creating exciting new growth vectors for ACV.
This includes delivering an expanding suite of innovative products and services into the dealer wholesale market, and over time, entering new domestic and international markets that we believe can significantly expand our TAM. The last element of our strategy is continuing to deliver operating scale. ACV has a proven business model that is delivering growth at scale with very attractive unit economics, with structural operating leverage that we believe can yield significant margin expansion over time.
Before turning it over to Bill to discuss financial details on the quarter and guidance, I'd like to provide a background in ACV for those who are newer to our company. Since this is our first call together, we have many listeners who are just getting to know ACV, I will spend a bit more time on the company overview. With that, let me begin with ACV's mission.
Our mission at ACV is to build and enable the most trusted and efficient digital marketplace for buying and selling used vehicles with transparency and comprehensive data that was previously not possible without our investment in technology and people. Some of you have previously heard my diamond analogy. Imagine buying a diamond on the internet without knowing the four Cs of color, cut, clarity, and carat weight. Used vehicles are also extremely complex, and the value of a used vehicle depends fundamentally on its condition. ACV has fundamentally changed the used vehicle industry forever because of our investment in technology and people.
Exiting 2020, our digital marketplace had over 16,000 active participants operating in 125 territories across the U.S. As I mentioned earlier, we are aggressively investing in growth. We made great progress in the first quarter towards achieving our goal of 160 active territories by year-end.
Turning now to automotive, the market we operate in today, which is extremely complex and fragmented. Our flagship product, ACV Auctions, targets the wholesale market, which accounts for over 20 million units sold annually. This includes 14 million units from dealer wholesale and eight million units from commercial wholesale. Our True360 data product is positioned to serve the nearly 30 million retail units that dealers sell to consumers. Given the unparalleled transparency that True360 offers retail buyers, we see significant opportunity to expand this offering. In addition, our True360 offering serves the eight million vehicles that commercial accounts sell to dealers. Now, let's put some numbers behind the market opportunity. We view our addressable market in terms of our near-term and long-term opportunities. Today, we focus primarily on the U.S. wholesale market, which has significant runway.
At an average fee of around $500 per unit, we estimate the TAM to be approximately $10 billion in fees for our core marketplace. This would include transportation and other value-added services we offer. The $200 million we earned in 2020 represents a small fraction of the opportunity. The majority of our current transactions come from the dealer wholesale segment, and we are just now investing in the commercial wholesale opportunity, a multiyear commitment.
Additionally, our data services, such as True360, have the opportunity to address transparency on approximately 40 million vehicles, including dealer to consumer and commercial to dealer. Longer term, we believe our platform approach will resonate outside of the U.S. We also plan to continue developing products that help dealers purchase and trade in vehicles from consumers. Over the long term, we see the opportunity to expand beyond used vehicles.
Bottom line, we believe we have a significant untapped opportunity for growth. Let's dig into ACV's auction experience. Our team of over 750 vehicle condition inspectors go to vehicles wherever they may be, at dealerships or consumer driveways. We inspect vehicles with our proprietary tools, then launch them into a 20-minute auction. The reason we can sell a vehicle so quickly is because we have our buyer's profile informed by their favorite searches, including any customization to their filters, which enables us to send notifications to dealers when vehicles match their needs. The notifications include a link to view the vehicle's condition and ACV Market Report to get pricing guidance from similar vehicles. Dealers conveniently finalize their transaction, where they can purchase our value-added services like ACV Transportation and ACV Capital.
Every step of the transaction journey in our platform is powered by data and technology, which drives trust, transparency, and efficiency. Turning now to our technology. Our platform leverages data and technology to power our digital marketplace and data services, enabling our dealers and commercial partners to buy, sell, and value vehicles with confidence and efficiency. ACV's platform is comprised of our digital marketplace products and our data service products, which are underpinned by the ACV technology and data platform.
Additionally, our back-end technology leverages machine learning to reduce manual efforts in post-transaction processing, which it continues to enable greater operational efficiency. How does this all translate into our marketplace offerings? We deliver a comprehensive suite of products that help create a seamless experience and remove the challenge our dealers face during the traditional wholesale process. This includes our flagship product, ACV Auctions, which facilitates instant transactions of wholesale vehicles.
Thousands of dealers transact in our digital marketplace every day. Live Appraisal is used by dealers prior to owning a vehicle to quickly assess the value of a consumer's vehicle without taking any risk. Within 20 minutes, a dealer can auction a consumer's vehicle while the consumer is in the dealer showroom, bringing efficiency and trust to the transaction.
We pioneered Go Green, which is the wholesale market's first seller assurance service. Go Green provides the seller with a guarantee against claims of defects and vehicles that are not disclosed in our condition report. With ACV Transportation, we help our customers manage the entire transaction journey by delivering vehicles to the front door of the buying dealer. Finally, with ACV Capital, we are becoming an integral partner for independent dealers by providing a credit facility, which is creating both liquidity and stickiness to our marketplace.
Moving on to our data services. We offer data services for our dealer and commercial partners that bring transparency and insights into the condition and value of used vehicles, both on and off our marketplace. With True360, we provide a detailed vehicle report, including cosmetic and structural assessments. True360 enables us to extend the reach of our products to the dealer retail market, some of the largest dealer groups in the U.S. are starting to use True360. Our reports are integrated into dealer websites and included within the leading vehicle history report providers. Our commercial partners are also leveraging detailed True360 inspection reports to better understand the value of their vehicles and sell their used inventory. Through our ACV Market Report, we provide transaction data and condition details to help dealers assess the value of used vehicles.
This gives dealers another tool to determine pricing strategies for their vehicles. Let's now look at how our marketplace, data, and technology combine to power significant network effects. As more marketplace participants join our platform, we can provide greater liquidity and a better experience, leading to greater scale. This, in turn, enables us to collect more vehicle and market data, bringing greater efficiency and more products. These reinforcing flywheel effects continuously improve our digital marketplace and data services for our customers. Ultimately, this drives greater liquidity, greater scale, and greater efficiency, which is demonstrated in our attractive unit economics. With our continued investment in technology and people, we believe we have significant avenues to drive long-term growth.
Within our marketplace, our growth will continue to be driven by adding new territory in the U.S. and further penetrating our existing territories by attracting new participants while gaining additional wallet share from our customers. In some of our more mature territories with our longest-running customers, we see dealers that drive up to 100% of their wholesale traffic through ACV. We've already made strides introducing ancillary services like ACV Transport and ACV Capital, and there's a long runway of growth in these areas. We see opportunities for more. On the data service side, we're focused on helping dealers navigate the used automotive landscape by providing trust and transparency and services they need to compete in the digital world. Everything we're doing represents incremental opportunity to provide more value for our dealer and commercial partners, and we think this opportunity extends internationally.
Lastly, M&A can be an accelerant to all of this if we find businesses that match our objectives. Let me wrap up with our ACV leadership team. We founded ACV with the core principle of investing in people and technology to bring trust and transparency across the entire used vehicle market. We have a unique blend of talented teammates with a broad section of backgrounds and experience, and I'm excited to have them by my side as we continue on the ACV journey. With that, let me turn it over to Bill.
Thanks, George, and let me also extend my welcome to our first earnings call. I'll begin with a review of our first quarter results. We are very pleased with our performance in the quarter. We delivered strong revenue of $69 million, which generated year-over-year growth of 64%. Adjusted EBITDA loss of $12 million or 18% of revenue was a significant improvement over our Q1 2020 results. This performance was driven by our strong revenue growth, significantly outpacing our total operating expense growth, which underscores the inherent leverage in our business model. Cost of revenue as a percentage of revenue improved by approximately 1,200 basis points year-over-year, which was driven primarily by an increased mix of high-margin auction marketplace revenue. Total operating expenses, excluding cost of revenue, as a percentage of revenue, improved by approximately 2,800 basis points.
To put this in context, we delivered 64% revenue year-over-year growth on essentially flat SG&A expense growth, once again highlighting the leverage in our marketplace business model. Let's turn to some additional detail on revenue. We have a diverse mix of products and services. Our auction marketplace revenue comprises about half of our revenue today, with our customer assurance offering and our emerging value-added services making up the other half of our revenue. We had very strong performance in our core auction marketplace business, with 92% year-over-year revenue growth. This strength was driven by a combination of strong unit growth and the attractive pricing environment George highlighted in his remarks. This business continued to deliver very strong profitability. Moving on to some additional operating results.
Our business model has delivered some impressive growth over time, and despite the larger scale of our business today, continues to deliver strong unit growth and marketplace GMV. To help illustrate the underlying growth dynamics and efficiency of our business model, it's useful to view our historical territory performance. As you can see in the first chart, as our territories mature, our unit production grows exponentially. This is a classic land and expand model, and we believe we're still in the very early innings here, and there is significant room to grow in our newer territories.
In the second chart, we illustrate the cost efficiencies we've experienced as our territories mature and gain significant operating leverage, typically reaching breakeven in year three or four. To put a finer point on the operating leverage in our business, we're showing historical Adjusted EBITDA margin.
In 2020, we had our first positive Adjusted EBITDA quarter in the third quarter as demand for used vehicles significantly outpaced supply. This drove strong growth in customers and units sold, and we benefited from significant operating leverage in our business model. As I will discuss in my guidance commentary, we are ramping our growth and technology investments this year, which will, of course, impact our Adjusted EBITDA margins. However, we think it's important to recognize the underlying operating leverage in our business model that we believe over time can produce significant margin expansion. Now I'll turn to guidance. For the second quarter of 2021, we are expecting revenue of $72 million-$75 million, a growth rate of 60%-67% year-over-year, and an Adjusted EBITDA loss of $20 million-$22 million.
For the full year 2021, we are expecting revenue of $307 million-$313 million, a growth rate of 47%-50% year-over-year, and an Adjusted EBITDA loss of $79 million-$82 million. Our guidance assumes that the favorable market dynamics driving strong demand and higher unit prices will continue in the near term, but to be prudent, we've assumed a more normalized environment later in 2021. Finally, on guidance, to my earlier point about our investment plans, we are expecting total operating expense growth of 62%-64% for the full year 2021. To wrap up my comments, let me highlight our strong capital structure. Following our recent IPO, we ended the first quarter with $616 million in cash and equivalents and $7 million of long-term debt. Please note that $98 million of cash is associated with the float in our auction business.
Specifically, we generated $46 million of cash flow from operations during the quarter due to an increase in the float on our marketplace of $53 million since December 31, 2020. The amount of float on our balance sheet can fluctuate meaningfully, driven by business trends in the final two weeks of each quarter. With that, let me turn it back to George.
Thanks, Bill. Before we take your questions, let me summarize. We are extremely pleased with our execution in the first quarter, which illustrates the momentum we're seeing in the market for our leading digital platform. We've made significant progress in redefining the wholesale vehicle market, but we're still in the early innings, and we have a number of exciting growth opportunities that we believe can meaningfully expand our addressable market. Data and technology is core to our advantage and will remain a strategic priority as we deliver new and enhanced services to the market. We have a proven business model that can deliver scalable growth with attractive unit economics and structural operating leverage that we believe will drive significant shareholder value. With that, I'll turn the call over to the operator to begin the Q&A.
Thank you. As a reminder, to ask a question, you will need to press star one on your telephone. To withdraw your question, press the pound key. Please stand by while we compile the Q&A roster. Our first question comes from Ron Josey with JMP Securities. Your line is now open. Ron, if your line is muted, please unmute. The next question will come from Michael Graham with Canaccord. Your line is now open.
Hey, thanks so much. Appreciate all the color on the call and congrats on the quarter. I wanted to ask two questions, if I could. One is, your territory expansion is tracking well, and you have improving economics in your more mature territories. That has to be balanced, I guess, against when you go into new territories, the economics are a little bit kind of compressed. Can you just talk about the balance between those two factors? The second thing I just wanted to ask is any plans you could share regarding ACV Capital and just sort of milestones to expect there.
Thanks, Michael. Appreciate the kind remarks. First, on the territory expansion and how it relates to building up the teams. First, keep in mind, we've been at this, as you know, for over four years, and we have a playbook. When we first open up a territory, obviously, we don't have any customers, but we hire our vehicle condition inspectors. At that point in time, you've got the cost, in essence. You're building up your customer base while you're opening up the market. You fast-forward, let's say, four years later, Michael, as you know, at that point, all of a sudden, just for example purposes, you're selling 1,000 cars or plus a month, and your inspectors are getting very efficient. You're getting quite a few vehicles per dealer per stop.
That's why you see when we went through the roadshow, when we described their model, described how the model scales. We really go from a territory, its early days, where you're basically less efficient until once you're three, four years out, you become extremely efficient in the model. Hopefully, that answers your first question.
On your second question, from an ACV Capital, we achieved our goals in the first quarter with significant dealer adoption attach rates. We're very excited about ACV Capital. We're focusing the product on bringing transparency to the fintech side of this sort of business, if you would. Meaning, while a dealer is transacting and buying a used vehicle, they know what it's going to cost them for capital, and dealers love that. The traditional models were a little complicated, trying to determine between all the various fees what it actually costs for capital.
Our model's very transparent. While you're bidding and while you're buying a car, you know what it's costing you. You also get the broader ACV service model. So far so good, and we achieved or actually exceeded our goals as it related to ACV Capital for Q1, and very excited about what's coming up next. Hopefully, Michael, I answered both questions.
Yeah, it does. Thanks so much, George.
Sure.
Thank you. Our next question comes from Nat Schindler with Bank of America. Your line is now open.
Yes. Hi, guys, congratulations on your first quarter as a public company. George, you alluded to macro concerns in the market. We've heard from your offline competitors of the challenges of new dealers not wanting to sell off their used cars that come in because they just don't have enough new cars to replace them with, so they have space on their lot, and thus fewer cars coming into the auction.
Obviously, that's not really affecting you guys that much given your results, but accelerating results. Can you walk us through what has been happening on the macro side and how you think this will evolve over the year? Specifically, when we're hearing that the manufacturers aren't likely to even be up to previous production levels until Q4, so probably supply of new cars is not going to be up until later into 2022.
How do you see this evolving over the course of the year?
Yeah, certainly, Nat. Thank you, thanks for the kind regards. Much appreciated. I'll try to describe this for you sort of in the way dealers are looking at this, obviously, which the majority of our supply today comes from dealers. This trend, I would say, started in really Q4 of last year. Generally, our franchise dealers, our new car dealers, are selling less cars, selling less new cars.
By selling less new cars, now they had less trades coming in for those new car sales. Some of that was made up by the increase in used cars for some dealers. Not for others, meaning the total car sales with any one dealership, we look at new plus used, may have been lower for some of them because of the fact that they sold less new cars. Some made it up by the used car side.
Either way, they had less trades. With less trades, to your point, some of them have decided to keep some of the cars that would've been traditionally wholesale. That mix was already happening to us in Q4 of last year. It was already happening in Q1 of this year. You've seen us have tremendous growth while facing this sort of change in the market of the franchise dealers really needing more inventory. What we're also seeing is you've also seen our GMV increase. If you look at it as ASP segments, that has increased partially because franchise dealers are also buying in our platform now because they need vehicles. It's really interesting. I would say, on the first part of your question, yes, these have been challenges for dealers.
We've been in a great spot because we're both on the supply and the demand side. As these macro things are going, sometimes it helps in supply, sometimes it helps in demand. Either way, we've been able to grow through this very significantly. When we look out, what we're thinking is you'll hear trends of new car supplies will return back to normal by Q1 of next year. Whether it ends up being Q1 of next year, whether it ends up being Q4 of this year or sooner, we're going to be prudent on how we think about the year. As we think about how the supply, from having more new cars and overall more cars in the inventory, dealers will face pricing challenges as it relates to used cars.
We think they should really consider using ACV Auctions, because with ACV, you know the value of the vehicle. You're not making any guesses on the vehicle. We think we're in a great spot to help them with these fluctuations with used car values. Really, in each of these cases, we're in a really good spot to benefit from these macro changes. Does that answer your question, Nat?
Yeah, partially. Looking at going forward, one of the things that's clear that these macro changes are causing kind of pricing to increase on used cars, as you alluded to as well, that helps your auction as well. Is your auction more levered to price or volume, or neutral? Would it be better if you were getting more units than getting higher prices?
Being the marketplace, you basically become the equalizer, right? Having more supply obviously gives you an opportunity to also theoretically sell more cars. The benefit on less cars in the marketplace gets reflected currently by having a higher GMV because dealers really are expanding the types of cars they're buying and selling on ACV. Nat, one of the things that's an interesting benefit is, during the roadshow, we talked about our GMV getting to the $10,000-$11,000 range a few years from now. One of the things that's really fascinating about Q1 is we got a little glimpse of the future, where dealers are both buying and selling a broader amount of inventory on ACV. I would say in the current term, by having less supply, we're benefiting. We're benefiting in effective rate or sell-through rate in the platform.
We're benefiting in GMV and other factors. Whereas at the end of this year or early next year, if the used car supply starts to tick up, we'll benefit by having more cars inspect. There's really pros and cons to both sides. Hopefully, that answers your question.
It does. Can I just one quick more for Bill, just so he doesn't feel left out?
Sure.
Thanks, Nat.
Yeah. No problem. Bill, just looking at your guidance, it looks like you're incrementally about $4 million of revenue, but incrementally about $9 million more EBITDA losses. Obviously, you said something about increased investment. How much, though, of that difference from Q1 to Q2 in the spending side is going to be something more prosaic, like cost of being a public company?
Hey, Nat. A couple of things. First, Nat, just to get back to your previous question to give you a little more context on pricing versus unit volume. If we look at our auction plus assurance revenue in total, about 3/4 of the increase in revenues is volume-based, and 1/4 is pricing-based. That gives you a little bit of context on the pricing side versus the unit volume side. Obviously the vast majority of our revenue growth is being driven by unit volume growth, right? Just want to cover that first.
Thanks.
Okay. In terms of our investments going forward, we increased quarter on quarter in Q1 our operating spend, this is excluding cost of revenue, a little north of $10 million sequentially. As you know, we're in investment mode across the business this year as we look to kind of drive long-term value and market share gains. In Q2, we're basically directionally looking at a similar absolute increase in OpEx spend. Slightly tilted towards SG&A, but for the most part, evenly distributed. We've talked in the past about continuing to make investments in product and tech, which we're continuing to do, and again, increasing our footprint on the go-to-market side. There, of course, is some increase in public company spend, but I wouldn't consider that frankly to be a significant driver. All those costs were previously anticipated.
If we think about Q2 and the rest of the year in terms of the OpEx envelope, it's pretty consistent with what we expected previously. There's no dramatic changes. Obviously, for our full-year guidance, we're flowing through the benefit from Q1 since our OpEx was about $7 million lower than we expected, even though we're ramping internal resources and talent acquisition as fast as possible, and we're tracking really well there. Hopefully, that gives you a little bit of color in terms of the go-forward view in terms of what we baked into our guidance.
Great. Thank you very much.
Okay.
Thank you. Our next question comes from Ali Faghri with Guggenheim. Your line is now open.
Hi, everyone. Thanks for taking my questions. I guess as a follow-up to the last question on the market trends, it sounds like the dynamics you're describing on the supply side were a headwind to your volumes in the quarter, but a tailwind to GMV. When in your guidance you talk about favorable market dynamics continuing in the near term before normalizing later this year, are you specifically talking about tailwinds to GMV and revenue per unit?
I would say that would be one of the primary differences as we look right now at Q2 versus thinking about Q3 and Q4 is we are ahead of schedule as it relates to revenue per unit, and we're ahead of schedule as it relates to GMV. We're, as yes, at this moment, being prudent. Whether it lasts longer or not at this point it really seems like it makes sense for us to stay prudent on this. Bill, I don't know if you want to add a little more to that.
No. I mean, what I would say, Ali, is we're trying to be just balanced in terms of how we guide you guys for Q2 and the rest of the year. I mean, you're right. In some sense, in Q1, there's kind of both headwinds and tailwinds. At the end of the day we kind of came out on the positive side of that. The numbers kind of bear that out. We're just trying to be balanced in terms of how we think about things from a guidance perspective.
Okay. That makes sense. Just a follow-up here. You talked about investments on the commercial side of the market, which seems like a big and largely untapped opportunity for the company. Most of those cars, particularly the off-lease cars, are sold on private label digital auction websites utilized by the OEM VIN codes, so it's a bit different than your current dealer wholesale business platform. Can you talk a bit about the products you're developing to target that commercial market, specifically within the off-lease category, and how you're hoping to maybe differentiate yourself from the incumbents given that market is already largely digital?
Yeah, certainly. I'll describe it maybe at a high level because we do have some upcoming announcements as it relates to our product strategy in this category in the short term. First, one of the major investment areas is our inspection platform. Within our inspection platform as you know, we acquired an off-lease inspection business, and we also acquired another business that was helping to understand the integrity of the vehicle frame, structural, other elements. We're hard at work creating what we believe is the number one inspection platform for commercial partners. That product will be released towards the end of this year. We're very excited about that investment. It'll help us and help commercial partners understand their assets, understand the condition, and help them really decide what they want to do from a pricing perspective with that specific asset. That's on the inspection side.
On the marketplace side of things, we mentioned in the S-1 that we have private marketplace capabilities coming out later this year. There'll be more to come on that topic because we have not broadly sort of marketed what our upcoming products are. We do have products coming out that will enable both dealer partners and commercial partners that would like to create a private marketplace for their own constituents. More to come on that topic.
Great. Thanks for the color, and thanks for taking my questions.
Yeah, certainly. Thank you.
Thank you. Our next question comes from Ron Josey with JMP Securities. Your line is now open.
Great. Thanks for taking the question. Apologies on earlier. Maybe two, please. Bigger picture, George. Clearly a great quarter and you're seeing more dealer sign-ups. Can you just remind us or talk a little bit more as to what might be the number one reason or a top reason or so why dealers wouldn't join the platform? Is it just inertia, things are working fine? Maybe just walk through that, please. I don't know if I heard before, but you talked about the ramping investments, and Bill, I know you talked about that as well. Just if you could touch Canada, things seem to be going really well and wanted to see if there's any updates on Canada that I might have missed. Thank you.
Yeah. Thank you. Thank you, Ron. First, we're really growing as planned. When you think about why a dealer wouldn't be using us, you saw that we took significant market share across the entire sector quarter after quarter. If you look back over the last four years, we've been growing very consistently. Dealers historically have ways to sell their wholesale, whether it be a wholesaler, whether it be the traditional auctions. There's relationships. These are long-term relationships. What we do is we go into a market, we build relationships, we tend to get a few cars, we prove ourselves, and then we earn more and more wallet share. We'll get to the point over a period of time where the dealer will end up giving us 100% of their wholesale.
What we're really seeing here, we really focus our metrics over the last four years. We've just been very consistent. We just keep growing quarter after quarter. That growth is that dealer adoption out in the field, helping them at their pace, dealer by dealer, to sort of move from their traditional ways of buying and selling vehicles to this very transparent and trusted way on the ACV platform that becomes extremely efficient for these dealers. We show up at the dealership, we inspect the cars for them, we take care of any arbitration or any issues. They're not on the hook for any of this as long as they buy our Go Green product, and it becomes very efficient for our dealer partners.
I think what you're seeing is we've had really exceptional and consistent growth quarter after quarter, and we've done that sort of community after community across the country, building relationships dealer by dealer. Does that answer your first question before I go to the Canada question?
Yes, it is. I totally get the land and expand strategy, and it's helpful to hear that. Thank you.
Great. On Canada, really no updates yet on our plan. We alluded in the S-1 that we'd come with a strategy before year-end of this year. This would be a little early to come back to you all, obviously. More to come. Our goal is to come to market with a strategy for Canada by the end of the year. I would say, I'm sort of sticking with that for now.
Got it. Thank you, George. Appreciate it.
Yep, certainly. Yep. Thank you, Ron.
Thank you. Our next question comes from John Colantuoni with Jefferies. Your line is now open.
Hi. Thanks for taking my questions. I wanted to dig a little bit more into guidance. It looks like full year revenue guidance is primarily flowing through upside from the first two quarters, at least according to our numbers. We're expecting pricing in the wholesale market to remain elevated until 2022. Maybe you can talk about the key puts and takes of your expectations for growth in the second half in the context of broader industry trends and how you envision ACV's market share progressing within the digital sphere. I have a follow-up. Thanks.
Bill, do you want to go first on this one, and then I'll go second?
Yeah. I'll start, and then you can add in, George. Yes. John, as I said in my prepared remarks, we're assuming in the near term, we continue to see the current dynamics play out in the market, right? If you look at our Q2 guidance at the high end, we're talking about higher growth versus Q1 at 67% year-on-year. F or the second half, again, we're just trying to be prudent in terms of how we model out the business, and we're assuming that these trends kind of moderate in the second half, right? Obviously, we've already proven that to the extent the current market drivers persist, we're going to benefit, right? We're just not assuming that in our guidance, right? Obviously, if it does play out differently, then potentially we can generate different results.
Kind of the underlying assumptions for the second half were just more balanced, and again, assume the market doesn't necessarily continue to persist with the same dynamics that we're seeing today. George, I'll let you kind of add a little more color on top of that, if you like.
John, I guess, first, thanks for the question. If you kind of learn the ACV culture and method, we really look back at our last four years to help us think about our quarters. We've been this very predictable company. We don't know yet what's going to happen with all these moving parts. We tend to just look at our historical data, and that's what you see us always do. Now, could the market be more favorable? That seems like that's what your firm is predicting. That could be the case, but for now, we rely very much on our historical data to predict the future, and then we'll see what the market trends are at that point. Is that helpful on how we look out?
Yeah, absolutely. Just wanted to turn to customer trends. Can you help compare retention and frequency of dealership customers that you've acquired since the wholesale market started to enter uncharted territory in the last three months? Maybe you could talk a little bit about engagement of those new customers, and what about that engagement gives you confidence you can retain them once the wholesale market starts to normalize in the second half. Thanks.
Certainly. We are seeing very high success in our new seller acquisition, bringing on dealers both selling and buying cars. We're very excited about how our team is growing. In the new territories that we've opened, we're very excited with the results. At this point, we don't disclose all the data, but I'll say our internal expectations on the number of units for our newest territories, the territories we just opened. We just went into a state, for example, and we are ahead of plan from our internal plan. That's very exciting, and obviously it gives us the confidence to look out and be very confident in the model we're providing to you all because our seller acquisition and retention remains very strong and very predictable. On the seller side it's going very well.
On the buyer side our NPS continues to climb ahead of others in the sector. Buyers would prefer to buy on ACV. It's more transparent. We work very hard to ensure when a dealer buys a car, on ACV, they're treated fairly every single car. Think car by car by car, whether it's transport, buying, et cetera. That not only reflects itself in our NPS and our increasing customer satisfaction, those buyers are willing to pay more for the car and ACV versus other platforms. We're very pleased with our results so far, both from an acquisition perspective on new sellers as well as buyers, and we're also pleased with the number of sellers that became buyers over the last quarter, buying more of these, you'll hear the term frontline ready sort of vehicles that the franchise dealers are typically buying versus selling.
All in all, we're very excited and saw we had a really exceptional Q1, and you're seeing us forecast out additional market share gains over the next several quarters.
Great. Thanks for the questions.
Thank you.
Thank you. Our next question comes from Rajat Gupta with JP Morgan. Your line is now open.
Great. Thanks for taking the questions and congrats on your first quarter as a public company. Just had a question. Just wanted to start off with the OpEx. The first quarter leverage was pretty strong. Probably, on an absolute basis, looks like the expenses were much better than at least what we had expected. Just curious as to, if looking at the full year OpEx spend, the 63%, is that tracking in line with what you had probably thought before? Is there some change to that plan, or do you feel like you need to do less or maybe just spread that out over a couple of years? Just curious as to if the spending year in the first quarter tracked as per your expectations, and is there some catch up to happen later? I have a follow-up. Thanks.
Yeah. Hey, Rajat. How you doing? It's Bill.
Hey.
A couple of things. Yeah, we did see a lot more leverage on the OpEx side in Q1. We basically came in at about $7 million less than we were originally modeling, and we've kind of flowed that through to the full year. The full year OpEx ranges are actually incorporates that favorable performance in Q1. What we're assuming is that we basically continue on the track that we had planned through the rest of the year. Even though we came in well below kind of our model in Q1, we're still tracking to all of our internal targets on the product and tech side in terms of operational investments that we're making.
The go-to-market side, we're kind of tracking really well and executing really well and we brought in a lot of people in Q1. We're continuing to ramp up our recruiting efforts to bring in more talent in Q2 and beyond. I would just say we're pretty much on track. At the end of the year, for the full year, we'll end up, based on our current expectations, below what we originally modeled for total OpEx.
Despite that, we feel pretty good about executing against our internal objectives. As you know, just as a reminder, this is an investment year for us. We believe now is the time for us to invest back into our business. There'll be some de-leveraging in our P&L as a result, but we believe it's going to set us up for kind of returning leverage next year and beyond as we continue to grow and get more scale and approach profitability and beyond.
Got it. That's really helpful color. Can you give us a sense of, I know you don't plan to break this out every quarter, but any sense of what the penetration rates were in some of the ancillary stuff like transportation, capital, any color you could provide on that front?
In terms of attach rates, I would just say we're tracking as planned. Our kind of objectives are to grow our ACV Capital business by increasing our attach rates, which have essentially been in the low single digits, we're still in the early days there. As George mentioned, we saw a nice improvement in Q1, we're certainly tracking against our internal targets. Transport as well. We've talked during our IPO roadshow about increasing our attach rates on the transport side in order to gain more scale, which over time will give us or put us in a position to generate some margin improvement on that side. ACV Transport, we believe ultimately delivers a better SLA to our sellers, it's very strategic. I would say on both fronts, we're really tracking as planned, if not slightly ahead of plan.
Got it. Just one last follow-up for George, maybe. Just on the commercial side of the business, just trying to understand, you mentioned about the private label brand opportunity there. Once you penetrate that channel and that starts to grow, how does that change your auction ARPU versus what you have currently with the dealer channel? As we know, like in an OPENLANE, their auction revenue per unit is roughly $100 or so, and then obviously there's ancillary services on top of that. Just curious as to once you penetrate more into those channels, how does the RPU change or just the economics change if it is meaningful? Thanks.
Yeah, certainly. Rajat, the way to think about it is how we've guided you all doesn't at this point really include private marketplace revenue opportunity. I would look at this and you could see how we're kind of looking at the market as there's kind of the current marketplace growth, and then second is the sort of product and TAM expansion. As we go to market on TAM and product extension, we'd come back and help everyone think about those new categories. A way to think about it is in the commercial sector, the revenue per unit from an open auction or an open sale typically is the same as what we're making today on a revenue per unit.
Some of our competitors, I would say from an OPENLANE auction where anyone can buy the car, not just a private constituent, the revenue per unit might even be higher than what we're getting today. From a private sale, as you know, the revenue per unit tends to look more like a cloud service, a very high margin cloud service. You're going to see very high gross margin. These are really fantastic products to be in. We're just getting started. We're almost done building the product. We'll have to roll that out. We'll start to go to market with that product. Look at products like that, are products for us to grow into over the next two to five years.
Look at that as sort of like the act two and act three of the company, where the act one right now is we're going to go out there this year and next year and just continue to grow market share. We've proven we've got what we believe to be the best product in the marketplace. We're going to continue to take share. In addition, we're going to bring product and TAM expansion. Once those products go to market, once we're comfortable to start speaking to future attach rates and revenue per unit, we'll come back around and maybe start to size up expectations in the future. Really much of what we've guided you all for this year on how to think about the core business is related to our auction product, our transportation, ACV Capital, True360.
Then there'll be additional products and TAM expansion that will come out over the next few years.
Got it. Great. That's really helpful color and thanks and good luck.
Thank you. Appreciate it.
Thank you. Our next question comes from Alex Potter with Piper Sandler. Your line is now open.
Okay, great. Thanks. I wanted to ask a question. I guess you're in 125 regions now. Obviously there's varying levels of maturity within each of them. Some of them, you're just coming up the hiring curve now, hiring very aggressively, looking to get your first inspectors out there, and some of them are on the other end of the spectrum. I don't know if it's possible to quantify it in this way, what percentage of those 125 regions would you say that you are sort of aggressively out there trying to add bodies? The follow-up to that would be, in this sort of goofy employment environment that we're in right now, it sounds like you're not having a difficult time finding people to do the work, at least if the revenue growth is any indication.
I'm just interested in any challenges or bottlenecks you might be having on the hiring front.
Yeah. Alex, thank you. As many of you know, leading our teammates is one of the topics I love talking about the most. Appreciate the question. We're hiring, I believe, across, if not all, the majority of our territories. None of our territories are fully mature. We've got a ways to go in hiring, even in the territories that have been operational for five years, and we're selling a lot of cars. In some of these markets, we're the number one provider in the dealer-to-dealer channel, but we're still hiring additional talented teammates. I'm not sure if it's every territory this month, but I would say the far majority of our territories right now, we're hiring people, and that will continue. On the second part of your question, we really are modeling our company to be one of the best places to work in America.
Yes, we want to be the most transparent and trusted way to buy a used car across wholesale, retail, and then beyond. In addition, we're really here to build a team of culture where we provide competitive salaries, sort of additional benefits, stock options. We provide health coverage, because I think that's really important to take care of their team. We provide training and education to help them learn. We're really over the top. What happens when you take care of your team, the word gets out. Yes, I would say others out there are probably having a hard time recruiting talent. We get thousands and thousands of applicants, and we're doing our best to make sure we're getting in there and interviewing and recruiting the right ones, and then training those amazing teammates across the country. We're doing well.
We're doing well from a hiring perspective. We're doing well from a training, and we're just getting better and better. Very proud of the team's efforts. Hopefully, that answers to your two questions.
Yeah. That was perfect. Thanks, and congrats.
Thanks so much. Appreciate it.
Thank you. This concludes the question and answer session. I would now like to turn the call back over to Tim Fox for closing remarks.
