Thank you for standing by. My name is Kate, and I will be your conference operator today. At this time, I would like to welcome everyone to the EVgo Q2 2025 Earnings Call. [Operator Instructions] I would now like to turn the call over to Heather Davis, VP of Investor Relations. Please go ahead.

Heather Davis

Analyst

Good morning, and welcome to EVgo's second quarter 2025 earnings call. My name is Heather Davis, and I'm the Vice President of Investor Relations at EVgo. Joining me on today's call are Badar Khan, EVgo's Chief Executive Officer; and Paul Dobson, EVgo's Chief Financial Officer. Today, we will be discussing EVgo's second quarter 2025 financial results, followed by a Q&A session. Today's call is being webcast and can be accessed on the Investors section of our website at investors.evgo.com. The call will be archived and available there, along with the company's earnings release and investor presentation after the conclusion of this call. During the call, management will be making forward-looking statements that are subject to risks and uncertainties, including expectations about future performance. Factors that could cause actual results to differ materially from our expectations are detailed in our SEC filings, including in the Risk Factors section of our most recent annual report on Form 10-K and quarterly reports on Form 10-Q. The company's SEC filings are available on the Investors section of our website. These forward-looking statements apply as of today, and we undertake no obligation to update these statements after the call. Also, please note that we will be referring to certain non-GAAP financial measures on this call. Information about these non-GAAP measures, including a reconciliation to the corresponding GAAP measures can be found in the earnings materials available on the Investors section of our website. With that, I'll turn the call over to Badar Khan, EVgo's CEO.

Analyst

Thank you, Heather. EVgo had yet another excellent quarter with strong operational performance and achievement of important strategic milestones. We had particularly strong revenue this quarter, up 47% versus the same quarter last year. Adjusted EBITDA was more than $6 million better than last year, bringing us closer to our goal of breakeven adjusted EBITDA for the full year. We had 4,350 stalls in operation and ended the quarter with $183 million in cash, cash equivalents and restricted cash, which is $12 million higher than the prior quarter. And most importantly, does not include $65 million in gross proceeds from the first drawdown from our commercial bank facility and expected 30C sale proceeds in August. On July 23, we closed on the largest and first-of-its-kind commercial bank financing for charging infrastructure in the U.S. for $225 million with the ability to expand to $300 million and have already received a $48 million first drawdown. This is a major strategic milestone for the company, enabling us to accelerate our expansion and diversifying our funding sources with low-cost, non-dilutive capital. As you will see, we expect to be able to increase our ending 2029 public stall guidance by approximately 3,500 more stalls than we had previously estimated to roughly 14,000 stalls. Strategically, EVgo is now very well positioned competitively as one of the best capitalized players in the sector. As always, we are focused on being disciplined in allocating capital, leveraging debt funding sources and the growth of our balance sheet. At this time, we do not have a request in front of the DOE LPO for our next advance. One of the many attractive features of the DOE loan is that there is no time limit, where we need to request advances for specific tranches of eligible costs we incur other…

Analyst

Thank you, Badar. I'll walk us through the summary loan terms for this facility. Flexible loan structure allows EVgo to build over 1,500 new public and dedicated stalls over the next 3 years and finances the 400 existing public stalls we added as collateral. As Badar mentioned earlier, facility allows us to finance stalls that wouldn't have been eligible for debt financing under the DOE loan. The interest rate is SOFR plus 3.25% with a 25 basis point increase at the beginning of year 5. Facility has a 5-year term and a 3-year deployment period. EVgo will be able to draw against the loan facility monthly after stall is operationalized for 60% of costs, including CapEx, capitalized G&A, and $31,000 of deployment expenses. As collateral for the loan, EVgo contributed 400 operational stalls into a project level SPV, and we received $48 million of gross proceeds in July after closing. We expect to see incremental network growth from this facility starting in 2026 as it typically takes EVgo 12 to 18 months to get a site operational. In terms of expected stalls in operation, we are now including estimates of growth net of removals, averaging roughly 130 per year through our EVgo ReNew program over this entire period, where we are removing legacy equipment from the network. EVgo now is fully capitalized to have roughly 14,000 projected public stalls by the end of 2029, which will increase operational efficiencies by leveraging economies of scale. This is approximately 3,500 stalls more than our previous estimate. As described in our fourth quarter 2024 earnings call in March, our unit economics continue to grow, and we expect to realize the operating leverage in our model through increased throughput per stall per day, leveraging fixed costs per stall, dependent costs such as rent and…

[Operator Instructions] Your first question comes from the line of David Arcaro with Morgan Stanley.

David Keith Arcaro

Analyst

Maybe first on the CapEx trends and offsets here. Great to see. I was just wondering if there was a geographic trend that's driving the capital offsets going to 45%. Were you targeting states in a different way based on demand that you're seeing? Or were there changes in state incentives? Just wondering what shifted that geographic trend around.

Badar Khan

Analyst

Yes. Well, look, I think -- thank you, David, for the question. I think that one of the key things we wanted to communicate here is that, not only are we focused on EBITDA generation with strong margins, we are also very much focused on delivering strong returns on capital for shareholders. And so, being able to lower our vintage CapEx per stall by almost 30% is very much aligned with that. Our first priority, of course, is to lower gross CapEx per stall, which is a trajectory we've been on for some time, and we've been successful at, and we are looking to continue with our next-generation architecture. On the offsets, we're absolutely pleased with where we are this year. We had a very high level of offsets for vintage 2024 in the 50% range. This year, the offsets are also looking like they're going to be very strong. We've seen that already for our first half year deployments where offsets are at that sort of 45% range. And these grants are really coming from all over the United States, to be perfectly honest. For the first half of the year, we have a lot of grants in -- grants and incentives from California, but the rest are coming from states like Florida, Ohio, Pennsylvania, Washington. And so, it's really all over the United States. I think a key point here, of course, is that regardless of what happens with federal incentives, state grants and utility incentives remain alive and well.

David Keith Arcaro

Analyst

And I was just wondering, any updates on the DOE loan in terms of availability, any recent conversations you've had around drawdowns that you would highlight? I know you're not currently looking for one, but curious just any background color there.

Badar Khan

Analyst

Yes. I mean, the project is performing very strongly, and that's the nature of the dialogue that we have with the DOE. It represents excellent credit quality, which hopefully you can see from our earnings today. We are not dependent on the IRA or 30C remaining in place, and so our dialogue with the DOE LPO staff remains a very productive conversation. I think the big strategic news this quarter is that we are no longer reliant on just one source of financing. The proceeds, as we just laid out today from the commercial bank loan and the gross proceeds from 30C are 3x what a quarterly advance would have been if we -- from the DOE this quarter. And so, we're very focused on not just being disciplined in our allocation of capital, but also disciplined in the growth of our balance sheet. And I think the good news or one of the many sources of good news is that there's really no time limit on when we request advances for eligible CapEx with the DOE loan other than the 5-year availability period. And so we can incur the CapEx now. And if we want to drop it into the DOE loans at some point within the next 5 years, we can or with the commercial bank facility. Of course, the commercial bank facility also allows us to fund stalls that are not eligible for the DOE loan, which I think is also very attractive. It allows all of our stalls at this point to be levered going forward.

Your next question comes from the line of Chris Dendrinos with RBC Capital Markets.

Christopher J. Dendrinos

Analyst · RBC Capital Markets.

I wanted to ask a little bit on the utilization rate this quarter. And I think you mentioned that there was a firmware update that went through. And then in July, you all had, like, I guess, maybe a significant increase in the utilization rate as that got rectified. Can you maybe just provide a bit more detail about that? Maybe how long the issue was lasting and sort of what you're seeing now coming out of that?

Badar Khan

Analyst · RBC Capital Markets.

Thanks, Chris. Yes, we did have a faulty firmware update at the beginning of the quarter in Q2, which is largely addressed at this point. We -- given that we had these issues, we did proactively take that opportunity to address some legacy charger issues at the same time and invested in maintenance to get -- really just to get a stronger network. We thought that made sense to tackle both issues at the same time. And then, as we said on the call, we can see average throughput per stall for July approach 300, which is quite a bit higher than what we saw in the Q2 average. I think what's really kind of most interesting here is that as an indication of true demand on the network, the average throughput on the chargers that -- where we weren't experiencing these issues was meaningfully higher than the chargers, where we were taking these steps on maintenance and the firmware. And I think that actually also really validates the decision and the path that we're on with our next-generation architecture where -- as I said before, I don't believe that really anybody else in our sector or very many others in our sector is able to do where we own the firmware and the development of critical components like the dispenser. And it's very much part of our journey of taking that customer experience to the next level.

Christopher J. Dendrinos

Analyst · RBC Capital Markets.

And then maybe on the NACS cable, and you highlighted some promising, I guess, call it, initial results from some of the deployments that you've done so far. I guess how are you thinking about deploying those longer term? And sort of what are you looking for that would maybe drive you to accelerate deployment? Or are you already seeing things given the kind of results you've seen so far that would drive you to maybe try to accelerate the deployment of those NACS cables?

Badar Khan

Analyst · RBC Capital Markets.

Chris, I mean, I think that the NACS cable and the autonomous vehicle space are both, I think, really interesting sources of upside for the company here. And we can talk about the AV space maybe later on. But on the NACS, we had a couple of pilot sites in the first half of the year. One was around technology validation. It's super important that we are, again, focusing on the customer experience, making sure the technology works. But the second site was really geared around are we able to attract more Tesla drivers. And I would say that I think the team is really pretty excited about the results. They're early, but what I said on the call is that Tesla driver usage was significantly higher on that site than pre-installation of the NACS cable. I do think it's early days. We're going to have about 30 cables, NACS cables, installed in August. And we're -- at this point, we're looking at 100 for the full year. These all retrofit before we start doing native, so -- not retrofit, but original equipment connectors in next year. But -- I mean, I think that if we continue to see what we saw so far, for sure, we'll be looking at our ability to deploy more NACS cables. But we want to just be certain about this. Everything that we've done at EVgo has been very thoughtful and very analytically based, whether it's the algorithms and site selection through to the AI in our marketing or AI agents in our marketing and customer outreach. Here, we don't want to pull out a productive CCS cable unless we're sure we can make it an even more productive NACS cable, which, again, the first site is definitely showing, but that's what we're looking at.

Your next question comes from the line of Bill Peterson with JPMorgan.

Unidentified Analyst

Analyst · JPMorgan.

This is [ Sikuo Yang ] on for Bill. Your updated build schedule looks quite robust, especially in the '28 to '29 timeframe. Can you help us understand why the builds are so back half weighted if you have the liquidity available to you now? And how do you think about balancing the EV VIO to DCFC ratio across the market versus capturing market share early on from competitors potentially?

Badar Khan

Analyst · JPMorgan.

Yes. I mean, look, I think the -- on the build schedule, there are really 3 things that have increased the schedule versus what we last indicated, which would have been about 6 months ago after the DOE loan. Those are the commercial bank facility and the fact that we are lowering our CapEx per stall. We've been talking about it for a year, but we've never reflected that lower CapEx per stall in our long-term forecast. And then lastly, we are generating quite significant excess operational cash flow. And so, we thought for simplicity's sake, we would assume that we'd be reinvesting that cash flow into new stalls. To be honest, the reality is, as Paul said, we've actually got fairly a reasonable amount of capacity for additional leverage in the back half of this 5-year period. But regardless, we think that's a good enough proxy. And that results in a very significant increase of stalls that we deployed that we're now fully capitalized for, which I think is the important point. In terms of whether we could go faster in the very near term, the next year or 2, we really are -- we've been talking about a 12- to 18- month timeline that takes from start to finish to deploy stalls. And that's still, I think, in place. I think in the medium term, though, we are looking at ways where we can reduce that overall elapse time. We know and the market knows that it is possible to deploy at a much higher rate. We've seen certainly one competitor deploy at a significantly higher rate. And of course, we've got a lot of folks in our team from Tesla today. And so I expect that over the course of the next year or so, you may hear me provide updates on what we're doing to be able to reduce that elapse time and effectively go bigger and faster.

Unidentified Analyst

Analyst · JPMorgan.

Maybe to follow up on an earlier question about utilization. Should we expect to see any kind of seasonality from here on out? And do you maybe expect to see increased usage by Tesla users with the NACS integration driving higher utilization over time? Also, do you recognize that also we've seen third-party reports that utilization kind of fell in the second quarter across the U.S. public network. So if there's anything else to call out there, that would be great.

Badar Khan

Analyst · JPMorgan.

Well, for sure, on the NACS cable, I mean, that's been the hypothesis that we've talked about, and so to the earlier question, we are quite excited about that. It's early days, and we don't want to get carried away. But I think it's really important just to bring out something that we've also been talking about, which is that we saw pretty healthy growth in throughput per stall sequentially, and that was because of rising charge rates. The higher the charge rate, the less the utilization we need for the same kilowatt hours dispensed. Our long-term forecast is actually only 23% to 26% utilization, but with an 80-kilowatt charge rate. And that actually translates to about a usage per stall -- kilowatt hours per stall that's about 60% greater than today. If we look back over the last 3 years, our charge rates have actually grown about 20 kilowatts in the last 3 years. And that's when we had slower chargers. 3 years ago, only 12% of our chargers were 350 kilowatt. Today, it's about 57%. 3 years ago, the charge rates in the cars were slower. So 20 kilowatts in 3 years going backwards, our long-term unit economics, as you can see in the chart, suggests a growth of just around 30 kilowatts in 4.5 years, but with faster machines and faster charging cars. And so we're -- this is a tailwind that we've been talking about, and I think we're really seeing that come through. And so it's really not just about utilization. It's really also about utilization and charge rate that's driving the throughput per stall up, and we're really pleased to see that. And to your question about seasonality, yes, we do have seasonality in charge rates typically. We have seasonality in different parts of our business. But on charge rates, they tend to be a little lower in the winter months, tend to be a little higher in the summer months. But the growth that we've seen in the last 3 years [Audio Gap] Operator, can we go to the next question?

Your next question comes from the line of Andres Sheppard with Cantor Fitzgerald.

Andres Juan Sheppard-Slinger

Analyst · Cantor Fitzgerald.

Congratulations on the quarter. I think a lot of our key questions have been asked, but I wanted to maybe hone in on self-driving technology. As we're ramping up robotaxis and self-driving across the country, curious if you can maybe give us a sense of kind of your strategy to capture as much of this market share as possible. How are you thinking about capturing the autonomous vehicles that are ramping up? And what are some plans to maybe differentiate EVgo?

Badar Khan

Analyst · Cantor Fitzgerald.

Yes. I mean, look, I mean, along with the NACS cable, I think that this is one of the 2 sources of upside in the business that's probably not in anyone's forecast. We do think it's a really interesting and potentially significant source of upside if indeed the AV space grows, which certainly it does seem as though it's going to. I know as I think you pointed out and others have, these are going to be electric vehicles and they're not looking to be charged in slow charging locations. That makes 0 sense. So we have been building and operating dedicated sites for autonomous vehicle partners for a number of years. Last year, we more than doubled the number of stalls at these dedicated sites to serve the space to 110 stalls. And we actually separated it out in our stall disclosure. And our public disclosure, it's sort of wrapped up in what we call ancillary at the beginning of this year. As Paul said in our guidance, we do expect to see a more than doubling of ancillary revenues this year over last year. And so we're pretty excited by it. We think that the kind of parties that we work with are pleased with the way that we're able to deploy fast charging speeds that are appropriate for the -- for those vehicles. Obviously, we're pretty good at it, building charging sites, whether they're public or for dedicated. And so we think that we've got a great relationship with these folks, and we're excited about the dialogue that we're having with them. And of course, now that we're fully capitalized and the commercial bank facility allows us to lever those stalls where we don't think they're eligible for DOE loan funding, we think we're in actually a really pretty good space and pretty good place.

Andres Juan Sheppard-Slinger

Analyst · Cantor Fitzgerald.

And maybe just as a quick follow-up. Can you just remind us what are maybe the key catalysts to look for maybe in Q3 and Q4?

Badar Khan

Analyst · Cantor Fitzgerald.

Well, look, I mean, we are just focused on executing the business, Andres. We're fully capitalized at this point. The charger issues that we talked about, the firmware and our choice to invest in the maintenance of some of these legacy issues is largely behind us, but we expect to be pretty much wrapped up with that activity by the early part of this Q3 period. I think that sort of just watch us execute. That's -- we're just heads down executing, and that's really what we're focused on.

Operator

Your next question comes from the line of Stephen Gengaro with Stifel.

Stephen David Gengaro

Analyst · Stifel.

Two things for me. The first is pretty straightforward. I'm not sure you'll want to answer. But when we think about your guidance for this year, do you think as you get into next year you'll be positive EBITDA in every quarter?

Badar Khan

Analyst · Stifel.

Yes, Stephen, we're not going to get into the guidance for 2026, it's just so early. But I think that if you think about what's really driving EBITDA for us, it is the measure that we've spoken about for the last year -- the last several years now, which is that throughput per stall per day, and that's rising. That continues to rise. It's rising sequentially. Yes, there's sometimes seasonality in that, again, in the winter months. It can be a little bit flattish in the kind of Q4 to Q1. But yes, that's going to be a big driver of growth in the business, and that's what we're seeing. So I think that's probably all I'm going to share at this point in terms of 2026.

Stephen David Gengaro

Analyst · Stifel.

And I guess the other thing, you mentioned earlier in the call in your prepared remarks about the economics of some of the chargers that are being driven by grants and maybe being a bit lighter in the beginning of the life cycle. Is that something that we will observe in the numbers [indiscernible] throughput per stall? Like just so we kind of know what to look out for. Or is it just not big enough to kind of really move those numbers around too much?

Badar Khan

Analyst · Stifel.

It can a little bit, Stephen. And I think that -- I think the really important point here is -- a couple of points here is that these are not federal incentives, right? So that's, I think, number one. I think that the state and utility space is very productive and supportive for EV charging infrastructure build-out. I think that the second point is that even if they're a little less productive in the first sort of periods, first few periods, these are phenomenally strong returns on capital invested. And so from our perspective, yes, we're obviously looking at EBITDA generation and very strong EBITDA margins, which is the business that we've laid out here. But it's also important to us that we're deploying capital that's delivering strong returns for shareholders on the capital invested. And I think that's what we're seeing with some of our choices. I think the fact that we've got such a large pipeline, which a lot of other smaller charging companies just don't have, allows us to move some stalls where we think we can get some great grants from one quarter to another or from 1 year to another. And that's what we saw this year where -- we did actually move some of our sites around. It forced us to push some sites from Q3 into Q4, but we thought that was worth it because the -- just the level of offsets is just so great and the returns, of course, on that capital is so strong.

Stephen David Gengaro

Analyst · Stifel.

And if I could ask you one other quick one. Understanding the NACS cable rollout, we -- big fans of Tesla, but not everybody is these days. Is there any targeted marketing that you're thinking about or you've done for Tesla drivers, because you see these stickers on Teslas that -- owners that are mad at Elon, et cetera. Is there -- has anybody thought about something like that you've done? Or are you thinking about any kind of campaign like that?

Badar Khan

Analyst · Stifel.

Yes. I mean, look, I know that this space is -- feels like it's very heavily politicized. We're running this business as an infrastructure business where we're deploying capital that's returning strong returns for shareholders and strong EBITDA generation, strong margins. We try not to get too political about stuff. We just think that's not necessarily always the best thing. However, we're very analytical. So where we're putting these NACS cables over the course of this year are in locations where we know there are Tesla drivers, where we -- those Tesla drivers, we expect will come over to our stations because there isn't a Tesla supercharger nearby. And as I said on the call today, we're just taking our capabilities to the next level. We've got these AI agents now that are creating messages, and they are figuring out which customers to send which message to at what time. And I think that we're -- that's sort of broadly what we're doing to get sort of the right level of interest at our stations at the right time. And I think that for the NACS cables, where we're attracting Tesla drivers with, frankly, charging stations that are faster. These are largely 350-kilowatt stalls that we're deploying today versus the supercharger network of 250 and closer to where they live with their amenities. We think that's a very interesting and successful -- should be a very successful approach.

Your next question comes from the line of Craig Irwin with ROTH Capital Partners.

Craig Irwin

Analyst · ROTH Capital Partners.

Paul, in your prepared remarks, you mentioned the ancillary revenue progression over the next couple of quarters, the fact that we should have a pretty strong fourth quarter. Can you maybe give us a little bit of color as far as the strength that we had in the second quarter, and how that's likely to materialize relative to your execution over the last couple of months? And anything else you could share to help us understand the way this is rolling out?

Paul Dobson

Analyst · ROTH Capital Partners.

Sure. Yes. So yes, we did have strong non-charging revenue overall in the quarter, both ancillary and the eXtend business. So the – with the Xtend business, I'll just talk about that one for a quick second. So what we saw was higher level of equipment sales with eXtend as our partners sought to bring forward equipment purchases. And then with the ancillary revenue, a large part of that growth is due to our hubs business. So when we set our guidance for the year -- the hubs business is a relatively new business. We're still learning what the economics could be and negotiated contracts. And so now we've got better line of sight overall into what our hubs business is going to generate this year in terms of revenue. So with the ancillary revenues, which is largely the hubs business, we expect it's going to more than double from last year, from 2024. We're expecting also to have a much higher fourth quarter as well, given some of the revenue recognition nuances in the hubs business. Again, it's largely because we now have better line of sight in the near term as to where we expect it's going to end up. There is some lumpiness to it, I will admit with the hubs business due to some of the accounting. And as we go forward and it becomes a much bigger part of our revenue mix, we'll provide more specific guidance on it that I think will be helpful.

Craig Irwin

Analyst · ROTH Capital Partners.

So then Bader, you're clearly executing well versus your financial targets, right? You're delivering, and you have been for several quarters. But it does look like you're adding a little bit of expenses to the model. So maybe there's a bigger opportunity or a different opportunity set. Can you talk a little bit about your priorities as you look for opportunities for investment over the next couple of years? Real-time pricing, I guess, is one thing that's got a lot of attention over the last several months. There are several things we could touch on. What do you see as the most important areas for investment at EVgo over the next several quarters?

Badar Khan

Analyst · ROTH Capital Partners.

Thanks, Craig. I mean, look, the single biggest use of cash in this business is the capital that goes into the charging infrastructure. And so we are very focused on both capital efficiencies per stall, that's gross CapEx per stall. We've talked about vintage offsets for quite a bit here. But the first priority is on gross CapEx per stall, which we've been lowering. But I think in part of that journey in terms of your question is the investment we're making into our next-generation charging architecture. We are -- our strategy is to be able to get the benefits of being vertically integrated without being -- without the risks and the cost of manufacturing. That's why that partnership with Delta Electronics is so important. It's why the -- our taking ownership of the firmware, which is the issue that we saw in Q2 is so important. And it takes that customer experience to the next level. That is what we're investing in, and we see that investment show up in OpEx. But ultimately, it's -- the goal there is to lower our gross CapEx per stall in line with the slide that we showed earlier for the second half of 2026. But you're right, we're also investing in marketing, in customer marketing, customer approach, the databases, these AI agents. We've invested over a long period in the algorithms behind our site selection, which we think is one of the many sources of competitive advantage for us. So you picked up on -- dynamic pricing is in an area of investment since last year, again, which we can see paying off in the unit economics schedule. So we're thrilled. But I think the -- I think one -- maybe the last point to leave is that the company has tremendous operating leverage. If you look at the fixed costs in this business versus the total G&A, it's pretty high. And so once you cover your fixed costs, all of that cash flow above fixed cost falls to the bottom line. And that's why this business model is just so -- to me, so compelling. The EBITDA generation after this year is really pretty exciting. And that's what we're trying to convey when we put -- every few months when we put out these long-term financials.

Craig Irwin

Analyst · ROTH Capital Partners.

Fantastic. And just another one, if I may. Firmware, you mentioned the firmware issue in the quarter. Can you maybe share with us what sort of a headwind this was on throughputs across the network? Or any other color for us to understand the financial impact?

Badar Khan

Analyst · ROTH Capital Partners.

Yes. I mean, look, we said that in July, the firmware issues, they're kind of -- at this point, they're largely behind us. We are -- we did, at the same time, decide to take some -- put some stalls into maintenance because we are seeing these issues anyway in terms of customer experience. So that will be largely addressed through the first part of Q3 But if you look at our July throughput, it was approaching 300 kilowatt hours per stall per day. And that's quite a bit higher than what we saw in the average in Q2, and that's probably a good enough proxy for where throughput -- for your question in terms of where throughput could have been.

Your next question comes from the line of Christopher Pierce with Needham & Company.

Christopher Alan Pierce

Analyst · Needham & Company.

I was just wondering, is it -- are you seeing increased competition for rideshare drivers? I mean, I know it's just one article, one headline, but we talked about 40-plus stalls going in at LAX and things like that. I just was wondering if sort of more people are realizing how interesting this business is or the frequency with which these drivers have to charge.

Badar Khan

Analyst · Needham & Company.

I mean, look, it's hard because there's so many companies in the space that are private and small. It's hard to know, to be perfectly honest. When we look at our own throughput, rideshare has been pretty steady in the 20% to 25% of our total kilowatt hours for I don't know how many quarters at this point. It's usually maybe a couple of years at this point. So rideshare is going great for us. It's been a steady contributor to our kilowatt hours in aggregate. That remains the case. We're thrilled. We've been saying forever that rideshare is a significant source of upside. That's beyond that battery electric vehicle to DCFC charging ratio, which is also a macro supply- demand factor that benefits the business. So yes, we're thrilled. I mean, I think that a lot of companies, smaller private companies in this space, anecdotally, we wonder whether they'll be able to attract capital, quite honestly, just because they're smaller scale.

And can you just touch on, lastly, ASP per watt. It looked like it was up pretty smartly quarter-over-quarter, and that's after a 1Q increase from 4Q last year. I just wanted to kind of -- if you could touch on pricing power? Or is this dynamic pricing that you're kind of able to flex? Or is this people that are on a monthly plan, but because of the firmware issue, the charger that they go to was down, so you had a onetime benefit there?

So yes, we have seen our revenue per kilowatt hour pricing increase. As we've talked about on other calls as well, we're continuously testing our pricing programs, dynamic pricing. We're just talking about rideshare and trying to incentivize rideshare drivers to go off- peak and trying to influence the shape of our utilization curve as well. And it's all resulted in us having the ability watching customers' reaction to seeing how much we can move prices up. We also, though -- when we look to price, we also look at what is the revenue minus our throughput costs, which are mostly our energy costs. And so as energy costs increase or decrease, we want to make sure that we maintain a spread or widen that spread to some degree. And I think that's really the most important point in the quarter where we saw that spread increase last year from, I think, $0.29 a kilowatt hour to $0.32 a kilowatt hour, which is right in the middle of our long-term guidance. So we're kind of approaching the spread where we think long-term it could end up. But we'll continue to test these programs with customers, making sure that we're delivering value to our customers, retain them, looking at the long-term value of customers as well, not just the short-term pricing opportunities and to make sure that we're maximizing the value and increasing retention as well.
