(presentation)
Dakota Semler - CEO & Chairman
Thank you, everyone, for joining us. Since 2018, we've been transitioning fleets in targeted high-growth markets from internal combustion engines to electric commercial vehicles with industry-leading technology. We are proud to be one of the few commercial EV manufacturers with vehicles and customer fleets across the country. Xos continues to remain focused on scaling the business by centering on 3 primary areas.
First, our commercial team is keenly focused on bolstering our distribution and service footprint by establishing partnerships with key customers and partners in high-growth markets and providing service coverage in direct support territories. Second, we have built and continue to assemble a high-performance team with experience in scaling truck and electric vehicle manufacturing. Third, our manufacturing and supply chain teams remain incredibly focused on ramping manufacturing capacity and establishing stronger ties with our supply base.
I'll start this call by reviewing key fourth quarter highlights, our accomplishments in 2021 and briefly discuss why we remain excited about Xos' outlook. Afterwards, Gio will provide an operational update, including an overview of the supply chain environment, followed by Rob, who will provide an update on product development, and Kingsley will conclude with a review of our fourth quarter results and outlook for the first quarter of 2022.
During 2021 and the first quarter of 2022, we achieved a number of milestones that underscore our commercial momentum in several high-growth last-mile markets. We expanded customer relationships, such as our partnership with Merchant Fleet, the nation's fastest-growing fleet management company, to grow their EV portfolio for last-mile delivery. Merchant has committed over $2 billion towards fleet electrification with the intent to buy more than 40,000 electric vehicles. We're excited to be supporting Merchants' goal of having 50% of its fleet electrified by 2025 and 50% of its clients' fleet electrified by 2030. We also secured a multimillion dollar truck order with Route Consultant, a premium broker and FedEx Ground contractor to deliver 40 last-mile commercial vehicles in 2022. We also secured a purchase order from Southern Glazer's Wine & Spirits to purchase 10 first-of-their-kind electric delivery trucks. These vehicles will be deployed at Southern Glazer's Dallas-Fort Worth distribution center and will be used as part of the company's delivery fleet. This is the first major incorporation of electric vehicles into Southern Glazer's fleet. We are excited to work with a well-regarded leader in the high-growth last-mile food and beverage market.
In addition to these exciting customer announcements, we've broadened our dealer distribution network. We recently announced our partnership with Murphy-Hoffman Company, MHC, one of the largest commercial vehicle dealerships in the country. The MHC territory with Xos covers 7 locations across 6 states. This partnership will improve the Xos customer ownership experience and offer enhanced support and MHC Xos service areas with MHC service centers keeping on hand a full inventory of replacement parts to ensure customers keep their vehicles road ready and maximize uptime.
We also forged a strategic partnership with Yancey, the nation's oldest Caterpillar and commercial vehicle dealer to distribute Xos vehicles across the entire state of Georgia. This strategic partnership will allow Xos to leverage Yancey's existing infrastructure and facilities, including dedicated truck service centers and technicians across the state of Georgia. The Yancey partnership bolsters our existing dealership network in the Southeast through our relationship with Thompson Truck Centers. We remain confident about the commercial traction and the breadth and depth of our consumer base. We are pleased to have made initial deliveries to name brand customers, including UniFirst, FedEx Ground operators, Thompson Truck Centers and MHC during fourth quarter 2021 and year-to-date 2022. That momentum has only continued to grow into 2022.
Along with our commercial traction, the team has achieved several additional operational milestones for Xos in 2021. First, we completed our business combination with NextGen in the third quarter, adding capital to scale our deliveries and operations as well as an experienced new members to our Board of Directors. Second, we significantly expanded production capacity at our 2 Flex facilities and now have an annual capacity to produce 2,000 units between the locations. Over time, as the business further scales, these facilities can each scale to produce 5,000 units annually. Third, we made significant progress introducing new products and services to enhance the Xos ecosystem, including the Xos Hub, announced in August, is our stand-alone mobile energy storage and charging station offering. The hub is capable of charging 5 trucks at once with minimal infrastructure installation. It's part of our new business unit, Xos Energy Solutions, which provides infrastructure services to small and large fleets to accelerate large-scale deployments of commercial electric vehicles.
Also, in November, we unveiled our proprietary second-generation Lyra series battery system, which represents a significant improvement in design, resulting in enhanced durability without sacrificing modularity and efficiency. Our Lyra series features a 52% system-level improvement in gravimetric energy density and a 45% enhancement in volumetric energy density. We also increased our unit deliveries to 32 units in Q4 ahead of our previous financial guidance for the quarter.
Lastly, to support our growth, we continue to build a phenomenal team that combines experience and scaled automotive companies as well as EV start-ups. We've added key leaders in supply chain, program management, finance and engineering. Xos is centered on these key areas of the market that we view as the most impactful for fleet electrification in the Class 5 through 8 last-mile segment. Our team remains focused on execution and building on our growth as we expand our presence across several high-growth last-mile markets. We expect to continue to benefit from secular tailwinds as the need for clean fleet and logistics solutions is gaining momentum in both public and private sector as they continue to move towards a net zero carbon economy.
Now our COO, Gio Sordoni, will now share an operational update.
Giordano Sordoni - Co-Founder, COO & Director
Thanks, Dakota. While we were able to exceed our outlook for the fourth quarter, like our peers, we continue to experience supply chain headwinds that limit our production. As the entire world has been experiencing, there's tremendous obstruction in the supply chain. It makes it more difficult and more expensive for us to access the parts we need to build our vehicles. We've started to see some improvement in our ability to procure components, but I've described the outlook has improved, although uneven. We're doing everything we can to mitigate the effects of the supply chain crisis from bringing on additional talent to the supply chain team, increasing safety stock of our critical components, pivoting to new suppliers, in some cases, and domesticating supply from Asia to North America, redesigning components and expediting logistics costs -- expediting logistics when we absolutely need to. Some of these actions have led to increased costs, which Kingsley will address in his section.
As we move through 2022, we expect the supply chain environment to remain a headwind to growth, where we are better prepared to effectively navigate these headwinds as we strengthen our supply chain and logistics team. We recently announced the addition of Mike Chaffins to the team as our Vice President of Supply Chain. Mike is a tested industry veteran with 30 years of automotive experience at automakers like Toyota, Mercedes-Benz and Nissan, along with Tier 1 suppliers like Dana Incorporated. With the addition of more automation in our battery assembly line, we expect overall quality and production yield to improve, a key part of our ability to scale production. Chassis assembly at our Flex plants has outpaced battery production. We expect to increase battery production when we add an automated battery line to Flex 1 in Tennessee later on in the year. This is in line with our existing production expansion plans. Xos has and will continue to explore alternative battery suppliers, form factors, chemistries and system designs to mitigate the effects of a disruptive global supply chain.
And in addition to Mike Chaffins, Eos continues to bolster our operational leadership with the hire of key leaders like Steve Ivsan, who recently joined Xos as our Head of Program Management. Steve also brings decades of automotive experience to Xos, having worked in operations and leadership roles at companies like Tesla, Continental and Rivian. Steve plays a crucial role in continuing to build on Xos' product plan and building systems that scale as we increase production of our flagship X-Platform products and introduce new models in the coming year.
Importantly, as Dakota mentioned, we've significant production capacity to support these growth opportunities. Our Flex manufacturing approach provides an advantage in speed, cost savings and labor availability in a really tight labor market as we continue to scale production. As we look to the current year and our key objectives, you can expect to see continued ramp-up in the X-Platform as well as the introduction of several new vehicle products and software offerings. We've been hard at work on these initiatives, and we're excited to share more on them at the upcoming Fleet Week event.
I will now pass it over to our CTO, Rob Ferber.
Robert R. Ferber - CTO
We're very selective at Xos in terms of where we allocate engineering and resource and development resources. We continually review our product road map and priorities to ensure alignment with our deep focus on purpose-built products that materially improve value and total cost of ownership for our customers in the last mile Class 5 through 8 segment. 2021 saw a number of key engineering milestones, which align with our approach and provide significant improvements for our customers. Notably, we launched the Lyra series, our second-generation batteries with improved energy density and performance. Lighter batteries are critical to the commanding commercial vehicle use case and allow our customers to go further, carrying more freight while maintaining the TCO advantages that our vehicles provide.
In addition to battery developments, Xos invests in targeted key technologies to improve quality of life and TCO to fleet operators. We've made significant progress in the development of our over-the-air update module, which will allow us to continually improve our vehicle software backbone without causing any customer downtime. We've also progressed the development of the hub. Xos' mobile charging unit designed to help fleets electrify before traditional infrastructure can be installed. All of these products will be integrated into our unified software platform, the Xosphere. Initial customer feedback on the Xosphere has been resoundingly positive, and we're looking forward to showcasing major updates and feature additions to the Xosphere in our event in May. All of our products, whether it's our flagship step van, our new vehicle programs which we will be discussing in more detail in May, the hub charging solution or software features like the Xosphere, telematics and over-the-air updates, aligned with our targeted market focus in the last mile Class 5 through 8 segment and address key needs within that space.
We believe in engineering for an advanced mobility ecosystem as opposed to a pure product-based approach. This allows us to drive adoption in our segment by building the tools for all aspects of a modern electric fleet. While our vehicles are at the heart of these fleets, they are only a part of the puzzle. Our other products each fit into a specific area of need for that ecosystem. Energy solutions, including products like the hub, which can charge 5 trucks at once in any location, and our infrastructure services allow customers to use and charge our electric trucks right now anywhere. Xosphere, including telematics and over-the-air updates, allows us to continually improve the customer journey and experience and to optimize our product without removing vehicles through a service or negatively impacting fleet managers. Optimizations to modules and components, like the Lyra battery system, chassis optimizations or ongoing improvements to and development of additional advanced driver assistance features or ADAS, continue to make our product more competitive, safe and effective. This ecosystem approach is continually validated by the feedback we receive from our new customers and the support in other areas is helping to build confidence in electrification with Xos for our existing partners. This confidence has resulted in additional orders and deliveries from key partners like Loomis and FedEx ISPs.
Now in addition to product development, optimizing and improving our manufacturing process and supply chain remain major focus areas. As Gio mentioned, in 2021, we significantly increased our supplier diversity and took myriad steps to mitigate supply chain risk factors. We also implemented a variety of programs to make our manufacturing process more cost effective and efficient. This includes ongoing runout rate assessments and investments in automation and robotics.
To support our continual drive for better product, process and efficiency, Xos continues to invest in building a world-class engineering team. To that point, we recently elevated Scott Zion to Head of Engineering to help us execute in our ambitious plans and deliver new vehicle programs on time. Scott brings decades of experience to the role with previous roles at automotive power players like Ford, Navistar and Hino Motors. We're excited to share more about how we leverage our core technologies into products that further serve fleet customers and the overall last-mile delivery ecosystem in our upcoming Fleet Week event on May 10 in Long Beach, California. Please see us there.
Our CFO, Kingsley, will now provide an update on the 2021 financials. Thank you.
Kingsley Afemikhe - CFO
Thanks, Rob, and good afternoon to you all. I will now review our financial performance over the fourth quarter, then turn to our balance sheet and conclude with our outlook.
Our revenue in the fourth quarter increased to $3.3 million from $0.9 million in the same period in the prior year, primarily driven by an increase in unit deliveries. We delivered 32 units over the quarter compared to 5 units in the same period in the prior year. Our team worked diligently over the quarter to optimize production and deliver for our customers. On average selling prices, it's important to note that underlying demand in the industry remains strong. While you will likely see ASP variability quarter to quarter due to the mix of unit type, configurations of the units we produce, for instance, a variation in battery capacity and channel mix, we expect ASP to smooth out over time and be higher in 2022.
Our cost of goods sold for the quarter was $5.7 million compared to $0.7 million in the same period in the prior year. We experienced increased material costs and incremental logistics costs associated with exploiting the shipping of key components. We expect our gross margin to improve as we ramp volumes and benefit from higher fixed cost absorption. In addition, we anticipate the new expanded and automated battery line as our Tennessee facility will drive gains in manufacturing efficiency, improve quality control, increase production volumes and reduce freight costs. We expect to incur additional costs, however, due to higher material prices and uncertainty around supply chain logistics. As such, we are taking proactive steps with our enhanced supply chain team to source domestically where we can and are leveraging our engineering skills to design for cost optimization as well as part availability.
Turning now to expenses. Fourth quarter GAAP operating expenses were $23 million compared to $5.3 million during the same period in the prior year. Non-GAAP operating losses for the quarter were $23.8 million, and this excludes $1.7 million of stock-based compensation expense. This was slightly higher than our fourth quarter guidance, primarily due to increases in cost of goods sold. General and administrative expenses for the quarter were $8.5 million compared to $0.8 million in the same period in the prior year. And this change was due to planned headcount investments to support our growth as well as new public company costs. R&D expenses for the quarter were $13.2 million compared to $3 million in the same period last year. As Rob mentioned, we are making exciting progress in a range of new products such as our chassis cab, our Xosphere fleet management platform, and we believe these developments will meaningfully and positively impact our results in the coming years. We will continue to increase investments in R&D, but we expect R&D expenses relative to revenue to fall over the course of the year.
Turning now to the balance sheet. At the end of the fourth quarter, our cash and equivalents and investments amounted to $168.7 million, and this includes $3 million of restricted cash. Given the flexibility we have built into our operations, our existing cash reserves are sufficient to scale manufacturing, invest in R&D and build working capital. As outlined in our financial release, we have entered into a $125 million standby equity purchase agreement with Yorkville Advisors, which provides us increased financial flexibility to scale the business. Any funding activity under this facility will be untaken opportunistically as market conditions warrant.
We continue to be selective in our investments and are evaluating additional financing options. Inventories grew to $30.9 million, about $11.6 million of which was in work in progress or finished goods as 12/31. Our inventory position continues to reflect some of the steps we are taking to ensure sufficient supply of key components. Overall, net cash used in operating activities and cash paid for capital expenditures totaled $37.3 million. Our business model remains capital light, and we have closed the year with $7.4 million of property, plant and equipment. We expect capital expenditure of between $30 million and $40 million as we build out our Flex facilities and invest in engineering.
Wrapping up with our business outlook, we expect sequential growth in revenue and deliveries over the year with a greater weight to the second half of the year. Due to the uncertainty in the supply chain at this point, we're only providing guidance for the first quarter. As we gain more clarity on the supply chain, we'll expand our window. We expect deliveries to be in the range of 40 to 50 units and Q1 revenues to be in the range of $4.5 million to $6.3 million and non-GAAP operating loss in the range of $20 million to $25 million.
And I'll hand you back to Dakota.
Dakota Semler - CEO & Chairman
Great. Thanks, Kingsley, for going over our financial section. Before we dive into our Q&A, we want to share with everybody that we remain confident about Xos' deliveries for the end of the rest of this year. We're excited about the factors that we can control in our business and about making quarter-over-quarter sequential improvements in our deliveries in the supply chain and in the manufacturing and servicing of our vehicles in the field.
Now we'll take the opportunity to open it up for questions and address anything that may have come up during our previous presentations.
Operator
(Operator Instructions) So first up on our roster, we have a question from Daniel Ives at Wedbush Securities.
All right. Well, we'll move on in the meantime to Michael Shlisky at D.A. Davidson.
Michael Shlisky - MD & Senior Research Analyst
You hear me okay?
Dakota Semler - CEO & Chairman
Yes, we can hear you.
Michael Shlisky - MD & Senior Research Analyst
Just can we just first touch on the equity agreement with Yorkville just for a moment. Based on what you had for cash balances at the end of 2021, it sounds like this is more of like a -- wouldn't say a burden. But if things good out of hand type of scenario where you have to actually tap that, do you have any -- I mean, the base case scenario for your outlook for the year does not anticipate using any of that. Is that -- does that make sense?
Dakota Semler - CEO & Chairman
Kingsley, do you want to take that one?
Kingsley Afemikhe - CFO
Yes, absolutely. Thanks for the question. As you know, we have a lot of flexibility in our business model, and we're improving that out with new products as we've been delivering over the quarter. How we think about this is that this is an option that we assess as a management team, which we would use very sparingly and early in the situation where we think that it would be value additive for the company for our opportunities. Clearly, as a management team, we strongly believe in our company, and we think equities and prices are where it should be, and we like the extra flexibility. Overall, as you know, we are CapEx light and we are assessing a range of financing options, which are available to us because we're a real company delivering real trucks, and we have assets on the balance sheet that we can use for that stuff.
Michael Shlisky - MD & Senior Research Analyst
Okay. Also wanted to touch on the mix for a moment as well. In the fourth quarter, were there any of units that were sold to Wiggins or other kind of non-truck providers? And is there any part of that -- is any of that in the first quarter relate to anything to 2022 in your -- the Xos powertrain business?
Dakota Semler - CEO & Chairman
Yes. I'll start with responding to your question, and thanks, Mike, for that question. In fourth quarter, we did have several deliveries that went to powertrain customers, including Wiggins, which is one of our initial customers in that segment of the business, but we also delivered trucks in that quarter. And that's actually what drove a little bit of the ISPs and the ASPs that you saw towards the end of fourth quarter there. And we expect to continue making deliveries in the powertrain business throughout this year that will also be factored into Q1 as well as several other quarters throughout the year.
Michael Shlisky - MD & Senior Research Analyst
Okay. Let me just throw one more out there for you. I know you have some product launches coming up. I don't want to give it away here on the call, but can you give us any thoughts as to how far a field or vis-a-vis? Or are they in the Class 5 through 8, what you've been talking about all along? Or is this going to be like a variance in your current product? Any kind of narrowing down if you would, prior to May, I would love to hear, that you can share.
Dakota Semler - CEO & Chairman
Absolutely. So our focus still remains on solving what we believe is the most interesting segment in the electrification landscape, which is Class 5 through 8 last-mile and regional haul vehicles. So the new products that we're going to be launching are within those categories and not just supporting vehicles or fleets with actual vehicles, but also with the technology that is going to help them deploy vehicles quickly and rapidly make that transition to a fully electric fleet. So we're excited to be launching that at our Xos Fleet Week event, which is the week of May 10, and we're inviting all of our analysts as well as customers, some of our suppliers and other partners that will be in Long Beach, California, and it's going to be an exciting event to really see what we have to come for the rest of this year as well as for several years to come with new products.
Giordano Sordoni - Co-Founder, COO & Director
And Mike, just to add to that. I'm sure you've noticed focus is extremely important to us. Everything we do is focused around the fleet customer in that Class 5 through 8 segments and really with an aim at reducing their total cost of ownership so that they can grow the population of electric vehicles in their fleet as quickly as possible.
Operator
Next up, we have a question from Jerry Revich at Goldman Sachs.
Jerry David Revich - VP
I'm wondering if we can talk about the production ramp over the course of the quarter, where we exit rate from a production rate standpoint based on activity that was going on behind you folks. It looks like that might have been a better number than we started the quarter with. But I'm wondering if you could just comment on that, if you don't mind.
Dakota Semler - CEO & Chairman
Gio, go on.
Giordano Sordoni - Co-Founder, COO & Director
Yes. Thanks for the question, Jerry. It's definitely not as smooth as we'd like it to be. It's still lumpy because of the supply chain. From a capacity perspective, a team growth perspective, we're really proud of what we've been able to put in place. But the rate at which we produce vehicles changes a little bit depending on part availability. So we're still managing through that supply chain crisis, which affects that production rate, both on the chassis assembly side as well as the battery production side.
Jerry David Revich - VP
And in terms of the planned mix of products over the course of '22, I know we're not talking about number of units, but can we talk about how your expectations of vehicle type mix have evolved in this supply chain environment?
Dakota Semler - CEO & Chairman
Yes. So the product that we're shipping and we shipped in Q4 and continue to deliver through Q1 is really our step van product. It's our primary category, and it's what we plan to support through most of this year. We will have some other vehicles in the mix there, including powertrains and some of what we're going to talk about in the upcoming Xos Fleet Week. But the majority of vehicles that we're delivering and we have backlog for is in the step van or medium-duty parcel delivery and last-mile delivery category.
Jerry David Revich - VP
Super. Okay. And Kingsley, can I just ask on the CapEx plan for the year? Can you just update us on what expected expenditures are? And as we look at the SG&A and R&D run rate that we had in the first quarter, is that the run rate we should be thinking about?
Kingsley Afemikhe - CFO
Yes, absolutely. So the number we put out there for the full year is going to be $30 million -- between $30 million to $40 million, and that's going to be spending, as we mentioned, expanding the line in Tennessee and as well as some other engineering investments. So our business is very, very flexible, as you know, and is based around deliveries and working capital and the growth in the business. From a cash perspective, we're really comfortable where we are and investing in our business and the facility we've announced today gives us a bit of flexibility. But as I said earlier to Mike's question, we feel comfortable where we are cash-wise and we like to have that option there to tap that if we need to. So yes, we're in a good place.
Dakota Semler - CEO & Chairman
The only thing I would reiterate also to Kingsley's point is that a majority of our cash use is actually dedicated to building vehicles. We're putting products on the road every single quarter, getting them into customers' hands and not just in vehicles but also in our charging infrastructure solutions like the Xos Hub. And that's really unique in this space. We want to make sure that we continue to make sequential improvements every quarter and getting more and more vehicles on the road so that we can continue to support our growth and investments into future R&D and engineering.
Giordano Sordoni - Co-Founder, COO & Director
And even within the R&D spend bucket, there's a lot of focus on cost in the vehicle and part availability. So an example of an engineering project that we would undertake is how to reengineer a certain part of the vehicle or allow us to procure a component from North America instead of from Asia to help manage around this really difficult supply chain environment, both from a product functionality perspective as well as a cost-savings perspective and a logistics timing perspective.
Operator
We've got a question now from Steven Fox at Fox Advisors.
Steven Bryant Fox - Founder & CEO
Two questions, if I could. I was wondering if you could dive in a little bit more into the expansion that's taken place in Tennessee and yet to come in terms of how it -- what exactly is still to come relative to what you've done and then also how it would flow into benefiting the financials? And then I had a follow-up.
Giordano Sordoni - Co-Founder, COO & Director
Yes, I can take that one. Thank you for your question, Steve. The -- currently, the batteries that we produce are coming from our facility here at headquarters in Los Angeles. The investments that we're making are to expand battery production into that Flex 1 facility in Tennessee. So that will actually be producing batteries later this year, our Lyra Battery series in the Tennessee plant. So currently, what's happening in Tennessee is mostly chassis assembly but we'll add battery production capability there as well. And that will be an even more automated system than what we have in place here in headquarters in Los Angeles today.
Kingsley Afemikhe - CFO
Yes. And just to add on to that from a financial perspective. If you think about it from a gross margin perspective, we'll have reduced logistics costs. We'll have higher throughput, so absorption of costs over more units overall. And when you combine that with the work that we're doing with Rob and engineering and also supply chain and designing for optimization and also for price, that's what gives us the confidence in gross margin improvement over the course of the year.
Steven Bryant Fox - Founder & CEO
Great. That's helpful. And then just as a follow-up. Given everything that's going on in the supply chain and given current events of just the last month, and you guys called it out that it's going to be difficult for a while, why not focus more on powertrains? It seems like that would be the path of least resistance to get more commercial credibility, grow revenues, leverage your costs, et cetera?
Dakota Semler - CEO & Chairman
Yes. So I'll start there and feel free to add in. But we've really been focused on continuing to deliver vehicles because the demand is still very, very strong. One of the things that we've seen even as recently as the geopolitical conflicts in Ukraine is the price of fuel, and subsequently, the price of diesel fuel has gone up significantly. So in the wake of that, diesel fleets and commercial vehicle fleets have become even more likely to adopt electric vehicles because the TCO or total cost of ownership savings are even more advantaged as they make this switch. So we're seeing greater interest and demand and adoption still amongst our on-highway vehicle customers. But it is still a growing segment within the business, the powertrain segment. And so I think as we are focused on building our core business and supporting fleets, we want to make sure that we preserve all of our capital as well as our vehicle inventory and battery inventory for those core customers and then continue to support powertrain customers as that grows and we can make really more -- achieve more stability within the supply chain.
Operator
Moving on now to a question from Mike Ward, The Benchmark Company.
Michael Patrick Ward - MD & Senior Equity Analyst
First off, just on a strategic standpoint, it looks like you have distribution partnerships and then you have other agreements like strategic partnerships with Merchants and Yancey. How are you looking at it, like as we go out over the next 5 to 10 years? It seems like most of them are going to be through -- your deliveries will be through a lot of these partnerships or distribution agreements. Am I reading that correctly?
Dakota Semler - CEO & Chairman
Yes. Thanks, Mike, for the question. So to answer a little bit about our distribution strategy, we take a hybrid approach. In markets like California, where there's strong support from the local governments as well as we already have a strong existing service footprint from keeping vehicles on the road here for many years, we really are planning and intending to go direct. So we'll continue to support those customers with the direct Xos Services dealer where they can find their vehicle procurement needs met, all of their vehicle servicing, parts inventory as well as our Xos Energy Solutions where they can actually provide charging infrastructure for those customers.
Where the distribution partners have been incredibly strong is in some of those markets that we haven't already built and established foothold or a brick-and-mortar presence. So the announcements with Yancey and the announcement with MHC are really to help bolster our existing customer relations in places like in the Midwest and in the Southeast where we don't already have a lot of vehicles already on the road. And why we selected those partners is they're some of the strongest in their space. MHC is the largest distributor of Kenworth products in the country. And through their network, they built out a network of about 120 vehicle locations where they distribute vehicles from service vehicles and provide full-service leasing solutions. So as we're supporting our existing large national account customers and as they're bringing to the table more regional and smaller and medium-sized fleet customers, it becomes a great approach to support the market and to get vehicles distributed really across the country.
The other reason why it's important is we need to have service and support coverage whenever we launch in a market. A customer needs to know that they have the peace of mind their vehicle is going to be maintained day in, day out regardless of what happens. If there is a collision or anything that occurs to the vehicle, they won't have parts inventory on hand. So when we think about these distribution partners, they become a great place to have on-site parts inventory where they can support the existing vehicles in the field and even bring them up for charging if the charging infrastructure for those customers hasn't been deployed yet or if they don't want to have one of our hub solutions. So we really have been able to scale deployments and deliveries. As these partnerships are growing, we expect them to be a larger mix of the overall distribution spread, but we continue to anticipate some of our large direct national accounts to be a significant source of volume for us over the near and long-term horizon.
Michael Patrick Ward - MD & Senior Equity Analyst
And do they have exclusive agreements with you? Or can they bring in other suppliers?
Dakota Semler - CEO & Chairman
So most of these distributor partners are existing dealers. So the relationships are not exclusive. They sell existing diesel trucks. In the case of MHC, it's Kenworth, and Yancey has with Blue Bird. So they have several relationships that are already in place. But we're proud to say that we are one of really the only options that are electric vehicles that they're distributing and carrying inventory for those customers.
Michael Patrick Ward - MD & Senior Equity Analyst
Makes perfect sense. On the CapX side, I think the $30 million to $40 million you've targeted this year, Kingsley, that's down from some of your previous assumptions. Is that a timing or an efficiency, that change?
Kingsley Afemikhe - CFO
Yes. So it's a mixture of both, but it's efficiency only come to our CapEx investments, expenditures coming out lower than we forecasted in the past, which is great. We're able to achieve volumes, the scale of both of our Flex plants. And so looking through this year, we forecast continued efficiency and expenditure and really the ability to ramp up deliveries from both of those plants. As Gio mentioned before, the real limiting factor for us right now is supply chain isn't really that expansion in the capacity. And what we're doing is working to optimize the capacity to reduce the logistics costs, as I mentioned, and increase the efficiency by having the battery line in Tennessee, which is always in our plans.
Giordano Sordoni - Co-Founder, COO & Director
Yes. And that was always the plan with Flex manufacturing, was to not have a massive facility that we're only using a small fraction of. We wanted to be able to roll out these facilities in a capital-efficient way and add capacity as we grow. That's a really core part of the strategy. And our Flex manufacturing partners have done a lot more than just provide a building. They are key partners when it comes to setting up the manufacturing and working with our in-house manufacturing team to scale up production. They also provide labor availability in a really difficult and tight labor market, as I mentioned in my earlier comments. So they've been fantastic, fruitful relationships for us on the manufacturing scale-up side and also a great way for Xos' control costs.
Michael Patrick Ward - MD & Senior Equity Analyst
Okay. That efficiency should be ongoing. So as I look out the time line of when you turn that corner, being cash positive, it's probably brought forward by several quarters, assuming the supply chain gets back up to a more normalized level.
Dakota Semler - CEO & Chairman
There's a lot of factors that go into that. I think the supply chain is the greatest uncertainty, which we can't control everything within. But if we start to see more normalization towards the end of this year and into 2023, we do expect that those efficiencies and CapEx will help us get to that point sooner.

And moving on now to Donovan Schafer at Colliers Securities.
Donovan Due Schafer - MD of Sustainability
Guys, great quarter. Cool to see things coming along. I mean, again, of course, the supply chain is challenging, but that's true for everyone. So it seems like you guys are making pretty good strides in spite of all that. I am curious, Gio, if you can give any kind of sense. Just for overall context, what kind of a build rate could you obtain if there were no supply -- if the supply chain was just perfect, what kind of a build rate could you guys do?
Giordano Sordoni - Co-Founder, COO & Director
Yes. Thanks for the question, Donovan, the capacity numbers that we have spoken about in the past in reference to chassis assembly at our Flex plants is 1,000 each, so 1,000 chassis per Flex plant. But as the supply chain sorts itself out, we're anticipating being ready to scale beyond that and doing everything that we can. A lot of the measures that we're taking right now to mitigate the effects of the supply chain are not just diversifying suppliers. It's also reshoring or near-shoring components to North America to save on timing and cost. We're trying to avoid expediting components and air freighting from other countries. A good example of that is in our wire harnesses. That's a component that we traditionally source from Asia. And it's tricky because we've had to get involved not only at the Tier 1 level, but also at the Tier 2 level, helping our Tier 1 source connectors, for example. So that -- what we did in that situation is reshore that component to North America with our partners at Commercial Vehicle Group, CVG. And that's an example of one of dozens, if not hundreds of changes that we're making to help get ourselves back on track.
Donovan Due Schafer - MD of Sustainability
Okay. And then for ASPs, I was just curious if you can kind of give us -- one way to kind of roughly bracket or wrap our minds around things if you're really focusing on the step vans right now, you can imagine a version of the step van where it's a 60 -- maybe the lowest one anyone would buy would be a 60 kilowatt hour module. But then some people might want a longer range and go out to 120 or maybe even more. So what's the ASP range? And maybe I'm sure every contract may be different. But just roughly, is it for the shortest range full non-power -- not a powertrain sale but a full vehicle sale. For the lowest range offering, does that get to come in about 100 a day and then the longest range ones come in, I don't know, 180? Or I don't know what...
Dakota Semler - CEO & Chairman
Yes. I'll start really quickly just on ASPs when it comes to the vehicles, and then Kingsley, I'm sure you have additional clarification. But per ASPs, there's a lot of different factors and it's not just the battery system. It's also how the vehicle is configured, what box goes on it, what the powertrain is in it. If it has a liftgate, there's a variety of different factors. I think what we're trying to do as we go out into the market is build a vehicle that's going to be within 20% to 30% of a competitively priced diesel vehicle. And what that allows us to really deliver on is a total cost of ownership savings that the fleet can see within the first 3 to 5 years.
Now fuel prices going up have actually helped that TCO calculation, but we also have been impacted by material surcharges and supply chain costs. So year-over-year, we actually did take a price increase, and we do have some material surcharges that we're passing on to our customers that we've received from our suppliers. So we do expect to see some incremental growth in the ASPs just because of the environment we're in and the inflationary pressures on the supply chain. But ASPs do vary. And depending upon the product mix, some of which is still to be determined for the rest of the year, it will be some of those shorter-range vehicles and probably the base case is still a 100 mile range vehicle or 120 kilowatt hour step van and going up from there.
Donovan Due Schafer - MD of Sustainability
That's very helpful. We're always trying to read the -- do some kind of reading animal entrails or something, trying to interpret what the ASP might tell us if the mix is moving this way or that way or whatever, but I understand is there's been a lot of moving parts there.
So last question I want to ask about because this definitely intrigues me and I know it's not new for you guys. But the Xos Hub, you did mention that, Rob, you said that you guys have progressed that product and kind of making incremental changes there, emphasized some of its importance. And I think of -- I also cover solar trackers in the solar space, and I've realized there that the successful companies are ones with demonstration sites. They have to be able to get a customer to see how it installs. And it's kind of a different world there, but it's a real -- it almost seems to define success or failure in that market. And so I'm curious if you guys see the Xos Hub as that kind of -- on that level for EV -- for commercial electric vehicles? And just what are some of the particulars of what you've expanded? The ease of deployment, number of vehicles, what are you advancing there?
Dakota Semler - CEO & Chairman
Yes. I'll start, and then Rob, feel free to add more technical details. The reason for the hub was because we had customers that were experiencing the challenges of adopting large-scale electrification infrastructure, not just installing 5 to 10 or even 20 trucks, but how do we think about installing and deploying thousands of vehicles across a disparate network of different locations. So we developed the hub to be able to rapidly deploy vehicles and have charging infrastructure on site when those vehicles get delivered, even if permanent infrastructure can take anywhere from 6 to 12 months. And that customer that we initially started working with has begun testing and evaluating the units that we've built and ultimately has decided to really move forward with that. And we continue to see strong interest in the product to be able to rapidly support large deployments of vehicles in different locations.
The benefit of the hub is not to utilize it as permanent infrastructure. It's a temporary solution to help make sure that trucks can get charged in the near term as they're manufactured and come directly from the factory to a fleet depot or a fleet yard. So we're planning to continue to ramp that and working with customers on different configurations to meet their needs based upon the size of their depots, based upon the power input coming off of the grid and exactly how many vehicles are going to deploy across the country.
But Rob, I'm sure you have more context add to that.
Robert R. Ferber - CTO
Yes, 2 things in general. One, from a grid perspective, the hub decouples the timing of the charging of the trucks from the pricing and the timing of the power optimal availability on the grid. That alone gives you enormous economic capabilities. And so while we intend this to be temporary, there are business cases and benefits to them in not just the vehicle space, but in some adjacent markets. In some of those adjacent markets, we had a meeting this morning, for example, where one of them popped up. The world changes when you go from taking a glossy brochure to a customer to taking a product because then they start really seriously getting their heads around what they're going to do with it. And so one of the values of having even the earliest unit is that when we put them in front of customers, we get real feedback about, "Oh, well, now that I see it, now that I've got it here, actually need this little tweak or that little tweak or it's perfect." But until we get that in the customer's hands, now do something with it. We don't know which way the wind is blowing. So this is the most valuable forward-looking information as an engineer that I can collect is what's the customer really willing to pay for, not just what do they say in a questioner, what would you like? Does it levitate? That would be nice. Yes. Well, would you pay $100 million for levitation? No. Well, what would you pay for? And having a real product in the customers' hands makes that a crystal-clear conversation.
Giordano Sordoni - Co-Founder, COO & Director
Yes. Having that customer feedback has been really important for us on the hub as well as our other products. We've seen a lot of interest on the hub from unexpected places, not just fleets looking to charge commercial electric vehicles. So that's been really interesting.
And the other thing, Donovan, I think you asked about product development and some of the changes we're making. It's important that the hub be a connected product like our trucks. So that's one of the things that we're focused on, is making sure that we can pull data from the hub and help fleet managers and our customers make more intelligent decisions on how to use their capital equipment. So whether it's a truck or a hub, that's really the core of what we're doing. We're more than just a hardware company. We're more than just a truck OEM. There's also a layer of software and services behind our hardware products that make them a lot more valuable.
Donovan Due Schafer - MD of Sustainability
Okay. Great. Very helpful. I'll take the rest of my questions off-line.
Operator
All right. We'll move on to a question now from Bank of America Global Research, this is Sherif El-Sabbahy.
Sherif Abdul-Fattah El-Sabbahy - Research Analyst
Just wanted to ask about your dealership agreements. So we've discussed at length the advantage of having a growing dealership network and you discussed MHC and Yancey. Looking at 2 sort of original anchor dealerships, Thompson and SV Lonestar, we've seen deliveries through our channel checks to Thompson. But does the purchasing distribution agreement with SV Lonestar still stand? And are you delivering units against it?
Dakota Semler - CEO & Chairman
Yes. So we have delivered vehicles through Lonestar and their Texas locations. And we continue to make headway with them. As a customer, they've been really supportive and they've helped facilitate a lot of good dialogues with end-user fleet customers, but they are a part of our fleet network as well.
Sherif Abdul-Fattah El-Sabbahy - Research Analyst
Understood. And on the R&D costs, you expect some decline throughout the year. Can you give us a range of where you expect them to run through the year?
Kingsley Afemikhe - CFO
Yes. So we have a number of exciting projects that we're working on, which we'll be excited to talk to you about when you come to Fleet Week in May. The guidance we've said is that we will carry on investing in R&D. But when you look at it relative to revenue, it's going to decline over time. And I think what's exciting about Xos is the impact they were able to have with the capital we've deployed in our R&D. And as Rob mentioned, our R&D is super focused on a commercial use case and on near-term cash for near-term revenue. I will talk more about it in May.
Operator
Just doing a final check if any of our analysts have a brief follow-up question.
Dakota Semler - CEO & Chairman
If we also want to go back to Dan Ives, I'm not sure if he was able to get his audio working.
Operator
I don't believe Dan was able to rejoin. I will let you know that I haven't had any other one -- any other signals for questions.
Dakota Semler - CEO & Chairman
Great. Well, thank you, everybody, again, for joining our call this evening or this afternoon. We really appreciate the opportunity to share with you the exciting progress that Xos continues to make in our manufacturing environment as well as in our production environment, even amidst all of the supply chain disruptions that we've seen through 2021 and coming into 2022.
In summary, we remain incredibly confident in Xos' prospects moving forward. There is an incredible opportunity right now that we are at the center of in electrifying the medium- and heavy-duty last-mile commercial vehicle space, and Xos is already delivering product to fleet operators and some of the largest customers within those segments. We also continue to make progress on the manufacturing forefront and making quarter-over-quarter improvements in our delivery rates and our production rates within our facilities here in Los Angeles as well as in Tennessee and Mexico.
And lastly, we've actually really focused on making sure we're delivering the solutions that help fleets scale their electric fleets more rapidly. So with products like our Xos Hub, Xos Energy Solutions and the Xosphere, which Rob talked a little bit about and we'll share more at our Xos Fleet Week, really have helped fleets not only deploy electric trucks, but deploy them more smoothly and more rapidly, which is our end goal here.
Thank you, everybody, again, for joining us, and have a great rest of your day.
Operator
Thank you, ladies and gentlemen. Once more, thanks so much for joining us. That will conclude today's webinar. We thank you for your participation. And once again, have a wonderful day.
