Earnings Call Analysis

Guidance and Confidence in New Battery Samples

For Q1'24, the company projects revenue between $3.5 million to $4.5 million, grappling with a slower transportation time for ships from Korea to Europe due to the Middle East conflict. Substantial losses are anticipated, with an adjusted EBITDA loss of $24 million to $31 million, and a non-GAAP EPS loss of $0.29 to $0.35. However, there was a confident tone regarding output from the Malaysia factory, indicating that samples from the Agility Line are expected to be issued in Q2.

A Strong Finish to 2023 with Optimism for Scale-Up in 2024

A company's journey through a fiscal period can be likened to a marathon, with each quarter symbolizing a strategic sprint towards success. For this particular company, the final sprint of 2023—Q4—was marked by impressive financial athleticism, showcasing revenue of $7.4 million, a figure that raced well beyond expectations. This triumph was supplemented by promising developments; the company is on track to initiate battery production in its Malaysian Fab-2 facility come April and has strategically positioned itself within the expansive market of electric vehicles (EVs). Enhancing these strides were concrete dialogues with two leading smartphone OEMs from China, geared towards collaborative battery production, and an EV battery development agreement that substantially broadens the company's technological impact.

Financial Stamina Supported by Capital Reserves and Strategic Investments

The company closed Q4 with a sturdy financial backbone, boasting $307 million in cash reserves. Nonetheless, the quarter demanded substantial capital investment, with $29 million dedicated to capital expenditures and a further $27 million fueling operations. Not a company to rest on its laurels, it strategically utilized approximately $10 million—inclusive of cash on hand—in the acquisition of Routejade, foreseeing a tactical expansion in military battery markets both at home and abroad.

Q1 Forecasts: Navigating Headwinds with Caution

Forecasting in business often involves a dance with uncertainty, and for Q1 of 2024, the company's revenue expectations have been cautiously choreographed to range between $3.5 million to $4.5 million. External factors, notably geopolitical tensions in the Middle East affecting shipping durations, have been taken into account, leading to an anticipated adjusted EBITDA loss of $24 million to $31 million. Investors are advised to brace for a non-GAAP EPS loss between $0.29 to $0.35, as the fiscal rhythm temporarily decelerates.

R&D and Operational Tweaks to Drive Future Efficiencies

The corporate machine is ever-evolving, with Q4 witnessing an $18.5 million accelerated depreciation of Fab-1 equipment, pivoting the facility towards product development. Looking ahead, Q1 is set to mirror this depreciation, though with a heavier weighting towards R&D expenses. Yet, the operational beat is set to change, expecting a decline in expenses from Q1 to Q2 due to both the accelerated depreciation cycle completion and efficiency measures in Fremont. As the year progresses, OpEx is projected to hold steady or experience a slight uptick.

Technological Advances Poised to Energize the Smartphone and EV Markets

Technological innovation is this company's driving force, with significant improvements in battery life-cycle—the coveted 1,000 cycles for smartphone-class batteries—fast charging capabilities, and energy density. Sample shipments of their pioneering EX-1M battery are imminent, with promises of even more advanced EX-2M models to follow. The vision is clear: providing advantageous alternatives across diverse phone configurations without compromising safety or performance.

Capacity Considerations and Market Opportunity Evaluation

The question of capacity is the question of demand; as the company proceeds through qualification cycles with potential customers, decisions on production capacity will be tailored to the market's reception. With one line already primed to produce approximately 9 million batteries annually, the company remains vigilant, ready to expand its capacity in response to design win trajectories.

Operational Excellence with an Eye on Margins

The roadmap to financial robustness hinges on operational excellence and the achievement of high yields. By reaching the target of 90%-plus yields, the company can potentially sustain premium pricing for its products due to the unique value they offer. As the product transitions to mass production, meeting these yield targets will be essential to optimizing profit margins.

Seasonality and Revenue Trajectories: A Year-End Surge

In the cyclical tale of revenue, seasonality plays a pivotal role. The company experiences the second quarter as its fiscal nadir, with the fourth quarter typically soaring as the zenith. Revealing a pattern, the fourth quarter of 2023 significantly bolstered the revenue, underlining a strong seasonal uptrend that enhances the year's financial narrative. The annualized run rate for the first three quarters is around $18 million, with the end of the year promising even stronger performance.

Strategic Partnerships Hold the Key to Swift Market Entry

Expanding its market footprint is a multipronged strategy; one such route may involve exclusive contracts with major OEM customers for unique battery specifications. While the discussion of exclusivity is not off the table, it will come down to a solid business case with guaranteed volumes and favorable price points. The company is poised to ink joint development agreements, opening doors to agile integration of its technology into clients' ecosystems.

Raj?

[Raj Talluri, executive]

Thank you, Charlie, and thanks to everyone for joining us today. I'm going to kick off with a few high-level remarks, and then we're actually going to show you some new video of our Fab-2, featuring Ajay. Ajay is actually now in Malaysia, and he is going to show you some update on manufacturing there. After that, Farhan will cover some financials and the outlook before closing, and then look forward to your questions.Okay. We had a strong finish to 2023. And now, we have laid the groundwork on how to scale up in 2024. First, we reported record revenue of $7.4 million in Q4, well above our expectations. Secondly, we are in the process of completing our factory acceptance testing, and a good amount of our Gen2 equipment is now in Fab-2 in Malaysia, ready to produce the first batteries in April. It's very exciting to see that progress. Third, we made significant progress with our customers, both in smartphones and in EVs.Last quarter, we hosted the executive management teams from 2 of the top smartphone OEMs from China at our Fremont headquarters and very good discussions on how to collaborate on making batteries for their phones. Additionally, we entered into a development agreement with a leading automaker to validate the advantages of the Enovix cell architecture for an EV battery. Now, this significantly increases the addressable market for Enovix technology, and we have a strong pipeline of additional opportunities in this space. And last, we have gained significant confidence in reaching the 1,000 cycles on a smartphone-class battery, and we look forward to sampling it next quarter.As I look back at our accomplishments last year, which were substantial, we began the year as a new management team operating at an expensive, low-yielding California factory with a product portfolio that, frankly, was not very well aligned to the key large customers and the end markets that we wanted to go after. Now, in contrast to that, we exited this year with a manufacturing base in Malaysia, ready to produce industry-leading batteries, a seasoned team in Korea that has shipped batteries over 20 years that we acquired, and close alignment with our customers that led us to gain a really in-depth knowledge and detailed product specifications that is helping us build category-leading products targeted at the largest portion of the market, which is the smartphones.Now, we are engaged effectively with the world's largest smartphone OEMs at various levels. These companies are eager to harness our architecture to keep up with the demand for more and more power hungry applications by this AI megatrend. I'll show some data and touch upon this in a minute. But first, let's take a look at our goals. What we need to do this year is to position ourselves for the large inflection in revenue with smartphone launches is very simple. First, we need to demonstrate high- volume manufacturing on our Gen2 equipment in our Fab-2 in Malaysia.Now, I know seeing is believing. So we're going to show you a video of the Fab-2, featuring Ajay, and that we just made in the last couple of days that speaks to our progress. And of course, Ajay will join us for Q&A from Malaysia. I think it's pretty early for him there, but he's online there standing by. So, operator, go ahead and let's roll the video.[Presentation] That was awesome. As you can see, our confidence is very high around Fab-2. And we accomplished a great deal in a very short amount of time, and I'm really proud of everything the team has done.In addition to proving out manufacturing, this year, we will need to deliver samples of batteries around -- tailored to the smartphone specification for fast charge and very high cycle life. I'm happy to report that our global R&D teams have made significant progress in the recent months, and we're looking forward to sending our first samples of what we call EX-1M for mobile next quarter. By the end of the year, we'll have an enhanced version of this technology called EX-2M, which will also be ready to sample.Now, these 2 will be truly revolutionary products, and they will be the first smartphone batteries in the world that we are aware of that will have 100% active silicon anode, while also delivering 1,000 full charge and discharge cycles, along with the ability to really fast charge and increased energy density over the batteries that are shipping in the market today. The need for high energy density is critically important to smartphone industry. It's a huge $10 billion-plus addressable market.Now, to give you a greater appreciation for why these smartphones need a higher energy density battery, last quarter, we asked Tirias Research -- it's a team I'm familiar with from my days at Qualcomm -- to analyze the impact of the looming AI applications on smartphones. Now, the results of the study are actually staggering. I want to show this to you in a slide here. What you see here is on the left side, the global GenAI output forecast of the amount of video and image frames in billions. You can see in '23, 15 billion; 24, 59 billion; to 28, we expect it to be a staggering 2,500 billions of frames generated. And these are going to be on mostly battery-operated devices, on phones, PCs, laptops and so on.And what you see in the middle is actually very interesting data. What we did here is actually profile how much battery consumption in terms of how much capacity is used per hour in milliamp hours for different applications. On the left side, you see non-AI-based conventional applications. On the right side, you see the AI-based applications, so things like 4K video. When you go to 8K video, a lot of upsampling is done using AI applications. Things like YouTube that you're all familiar with on the left side, but on the right side, things like ChatGPT or Llama 2 chatbots. It's staggering that ChatGPT actually consumes more battery than running YouTube on your phone. It's pretty amazing. And this is just the beginning. And this is very important because this is what we are hearing from all our customers that they just need a much higher energy density battery.In fact, I just saw a couple of new phones launched by some of our -- the Chinese OEMs. And actually, the flyers for the phone is actually all about the AI applications that run. You can also see something similar for Samsung Galaxy advertisements. So the trends are clear. With our product road map and our customer relations, we are well positioned to enable the smartphone industry to really usher a new era of mobile computing. In addition to that, we are now thrilled to have our first deal done in EVs.And with that, I'm going to turn over to Farhan, who will provide a recap of our financials and then the outlook. Farhan?

[Farhan Ahmad, executive]

Thanks, Raj. So all the relevant financials are in our quarterly report, so I won't go into the details, but I'll just do a quick recap of the results and the outlook.For Q4, we delivered revenue of $7.4 million, well ahead of our expectation. We ended the quarter with about $307 million of cash and equivalents. Q4 CapEx was about $29 million. About $27 million was used in operation, and about $10 million of cash was used in acquisition of Routejade, net of the cash that we acquired as part of Routejade.As a reminder, we are accelerating the depreciation of Fab-1 equipment post our decision to stop manufacturing in Fab-1, as we decided to convert it for product development purposes. Our Q4 results included $18.5 million of accelerated depreciation. $6.2 million of this was in COGS. $12.2 million of this was in R&D. And $0.1 million was in SG&A. In Q1, we expect a similar amount of accelerated depreciation, but most of it will be in R&D expenses.Now, turning to our guidance, for the first quarter of '24, we are expecting revenue in the range of $3.5 million to $4.5 million. Now, there is some impact, a meaningful impact to our Q1 guidance because of the war in Middle East, which is causing a longer time for the ships to go from Korea to Europe. We expect for Q1 an adjusted EBITDA loss of $24 million to $31 million and expect non-GAAP EPS between $0.29 loss and $0.35 loss. I would like to note that our non-GAAP EPS loss does include the impact of the accelerated depreciation that I talked, which is about $0.10.And with that, I'll now turn to Raj.

[Raj Talluri, executive]

Okay. Thank you, Farhan. In closing, I'm super excited by all the work we've done in '23, and we set the framework for our business to scale in the years forward. And we have significant proof points to deliver in '24. And I'm super excited by -- as you can tell, by all the stuff we have going on in our manufacturing fabs and executing to these key milestones.So with that, I'll open up for questions.

[Operator]

We will now begin the Q&A session. Please note that this call is being recorded. Before we go to live questions, we are going to read the 2 most highly voted questions submitted by shareholders ahead of this call during the call registration.The first question is, will management address the current and future status of government contracts for batteries? Is there still a near-term 8-digit revenue opportunity? Or has management totally abandoned this?

[Raj Talluri, executive]

Yes. So, very good question. As we did last quarter, we continued to deliver batteries to the Army contract that we have, which -- these are BrakeFlow-enabled safe batteries that the Army will use in vests and so on. And we expect to continue to do that through this year. As we do that, these batteries are put into different kind of tests by the Army and a lot of qualification process and so on. Once that's done, we do expect that they will end up in higher volume production, and we will have a good business opportunity there.Also, with the acquisition of this company, Routejade, they have very good batteries that are actually being sold to the Korean military, and we see opportunities to actually market those batteries to the U.S. Army also. So, yes, we do expect to continue to do that.

[Operator]

The second question is, what is happening with the former production space in Fab-1 now that the Gen1 line has been shut down?

[Raj Talluri, executive]

Yes. Thank you for that question. So Fab-1, so we are not doing high- volume manufacturing Fab-1, but we are using it right now to make samples to give -- like EX-1M and EX-2M and so on, to give it to our smartphone customers to sample -- to validate the technology before our Fab-2 is ready. As I mentioned, we expect to produce cells from Fab-2 in Malaysia in April time frame. So we are actually using the current fab in Fremont for that. Also with this new EV opportunity, we have -- which we expected that we will need a clean room and a dry room and a facility to make those cells here, which we're going to do here in Fremont. So it continues to be a good R&D facility for us.

[Operator]

We will now go to the queue. [Operator Instructions] Our next question comes from Colin Rusch with Oppenheimer.

[Colin Rusch, analyst]

As you've gotten deeper into the customer conversations and testing on the smartphone side, can you talk about the number of SKUs you're expecting to have to make in the next 18 months to 24 months to serve those customers?

[Raj Talluri, executive]

Yes. Thank you for that question, Colin. So what's happening right now, I'll give you a little bit of color, taking that opportunity of that question. So what's happening right now is that we've got very detailed specifications from multiple customers. These are 20, 30 page documents on how the battery is tested, different temperatures, different size requirements, fast charge requirements, safety requirements and so on, from multiple smartphone OEMs. So we are now building samples and sampling -- and we will be sampling them soon to these customers with the requirements that they've given. And what we do is, we test the batteries to those requirements so that when we give them the cells, we are pretty confident that they will pass. It's something that I've always done in my past is to make sure we understand the customers' testing requirements, test them and then give it to them. And then, what we expect to happen is, after they pass the technology qualification, we expect to get different dimensions and capacities, so 5,000 amperes or 6,000 amperes, based on what smartphone it's going into. And each customer is a slightly different size. Like if it's going to flip phone, it's one size. If it's going to candy bar phone, it's going to be slightly different size. And then, we will make those particular form factor batteries from our Malaysia fab, get them those samples, they go through the rest of the qualification, and then you get to high-volume production next year.It's hard to tell exactly how many different shapes we'll need to do because we are sampling to multiple customers. And based on how quickly those evaluations on their side go, it'll drive that. I'd say probably in the single digits is what I think. It shouldn't be too many because I do think that a lot of customers will try to use a similar kind of cell because the phone form factor is kind of very similar between customers.

[Colin Rusch, analyst]

That's super helpful. And then, given the opportunity in mobility, there's certainly a lot going on in terms of vehicle design, pack design, and given the safety profile that you guys have and the potential for fast charge, can you talk a little bit about your expected pack size and how that might look for some of these vehicles as they look to optimize both space and the energy density in the vehicles? Are we talking about 60 kilowatt hours per vehicle? Or are we talking something more like 80 kilowatt hours or 90 kilowatt hours?

[Raj Talluri, executive]

Yes. Good question, Colin. So what -- just to be clear, what we are doing now is working with -- what we talked about is one OEM that's interested and there's others we are talking to on proving out the value proposition, right, proving out that we can control swelling, proving out that we can charge fast. Exactly what kind of cells they would be, how many they would be, what kind of EVs they would be? It's too early to tell. We will continue to update you on milestones as we get there. At this point, we're just proving out the technology.

[Farhan Ahmad, executive]

Yes. The only thing I would add is that they will have our architecture, our unique architecture. What's common is that all of these cells that we are working with automakers are with our unique architecture and will have fast charge as the unique differentiator.

[Operator]

Our next question comes from Bill Peterson with JPMorgan.

[William Peterson, analyst]

Maybe just to piggyback off that last question, it sounds like you said the key focus area will be fast charging. But can you just shed some light on some of the key milestones and timelines for this? What are the contribution and commitments from Enovix in terms of sampling testing? I guess, is there further appetite for Enovix, as well as resources as well to actually ink any additional agreements? Or should we just think of this single agreement for now?

[Raj Talluri, executive]

Yes. We hope to get samples out this year. That's our goal. We are working with other OEMs, too. But I can't really comment much further than that. It's kind of early stage, and we'll keep you updated as we make progress.

[William Peterson, analyst]

Okay. Second question. So when we think about EX-1, EX-1M and EX-2, I guess, what are the key changes you're making on the material side? Are the formulations and process -- manufacturing process fixed for EX-1M and EX-2? And I guess, if not, I guess, the formulations for EX-2, if they haven't been fixed, what are the issues or performance gaps you're looking to address before locking in the materials choices and process? Just trying to get a sense for how mature these are at this stage.

[Raj Talluri, executive]

Yes. Good question. So basically, if I look at EX-1M, it's built on top of what we have done in EX-1, which is adapt that technology to meet the requirements of the smartphone market. And when I say the requirements for smartphone market, there is a few key requirements. One is clearly safety. People really, really care about safety in phones. As you know, we have spent a lot of time on that, and that's one area we address. The second area is cycle life. Our previous EX-1 batteries ran up to 500 cycles. Our target in EX-1M is 1,000 cycles, which is basically doubling that. And that's a significant increase. And the third one is the ability to charge really, really fast. So if you think about a smartphone, when you have a smartphone, what a lot of customers do is, particularly with these AI applications, a whole day battery life is getting harder and harder. So when the battery life goes down, people like to be able to charge and get to 15%, 20%, 30% charge so they can go through the rest of the day. So that is a very important care-about. To do that safely and to do that in a way that it doesn't hurt the battery longer term is a very key care-about, and that's one thing that we feel good about now. And the third one is increasing energy density. So we have now looked at all the different phones out shipping in the market, and we believe that we can provide an advantage compared to that, while keeping fast charge, while keeping -- increasing the cycle life and also different temperatures. That's the other thing you need to worry about in these markets is that what temperature you operate the battery at, what top of the cycle charge looks like and so on. So those are all the things that EX-1M addresses. And again, these are slightly different based on each customer. Some customers want more cycle life and maybe a little less ED. Some customers want more ED and little less cycle life. So we are now in the middle of basically a target specification, which we have finalized now on EX-1M. And those are the batteries that we expect to sample from our Malaysia factory in April.What EX-2M does on top of that is actually continue to increase energy density. And you've seen us put out a slide before on where we expect to get there with that, while keeping the increases in cycle life, while keeping the increase in fast charge, while keeping all the safety parameters. Now, to be able to accomplish that, we have finalized a set of materials for EX-1M, cathodes, anodes, electrolytes, separators and so on. We have shortlisted what they will be for EX-2M. And in short order, we'll decide which ones. Some very promising results. So we're pretty optimistic of being able to get there.

[Operator]

Our next question comes from George Gianarikas with Canaccord.

[George Gianarikas, analyst]

I'd like to ask about your material supply chain. Earlier in the quarter, you announced an agreement with Group14. And I'm curious, first of all, how diversified your silicon supply chain is, and how extensive are the choices by handset vendors or device vendors into making that decision. Or is that purely a decision that Enovix will make in terms of which silicon they put -- you put into your batteries?

[Raj Talluri, executive]

Yes. So if you look at producing a battery that increases energy density but also meets all these other requirements, and I can't emphasize enough of that because ultimately, a battery has to meet the requirements that are required by the end product, which our customers make, cycle life, fast charge, swelling at the end of life and so on. It's a function of not just the anode, but it's a function of the silicon anode, a function of the cathode, and more importantly, the electrolyte because in a battery, the electrolyte, when it interfaces the cathode, has certain properties, a certain way, it needs to behave. When it interfaces the anode, the other side, it has to behave in a certain way, all at the same time being able to pass lithium ions. And the separators play a big role as to how thick is a separator and how do they handle the stack pressure and so on. So the recipe of choosing the right cathodes, right anodes, right separators, and putting them together is really the intellectual property that we have at Enovix and experience we have here. So we -- like I said, there's multiple choices on anodes, multiple choices on cathodes, multiple choices on electrolytes, and that is the intellectual property that we have. We are constantly looking for new materials. We were very excited by the results we got from the Group14 material, and that team has been super supportive. We're also talking to other people. Supply diversity is also important. And ultimately, what we're going to do is to find the right recipe for the right end applications based on the customer feedback. So that's kind of the best way to answer that question.

[George Gianarikas, analyst]

And just as a follow-up, I'd like to ask about your timelines here on the FAT and SAT testing. Your confidence level in terms of getting out samples for the Agility Line in the second quarter -- I know that on a recent podcast, you discussed you saw a little bit of a push-out in some of the timelines here. Can you just kind of reiterate the -- and give us confidence that you can get those samples out in the second quarter?

[Raj Talluri, executive]

Yes. I'll answer a little bit at high level, and Ajay, feel free to add. I know he's in Malaysia. I'm not sure how good the line is. But basically, we feel very confident that we're going to get samples out in April time frame to our customers. And we did announce some delays on FAT of one of the zones. And again, you got to remember, these are very, very complicated things we are doing. These are tens of machines, all working in tandem together. One thing both Ajay and myself and the leadership team we've done is we're not going to cut corners, right? We're not going to cut corners in the requirements of FAT, in the requirements of SST, how much material we need to run, what yield they need to come up with before we take acceptance of any of these machines for our customers from our suppliers. So, that has caused some amount of back and forth with our suppliers, but we feel good now that it's within reach, and we feel good about the machines we have received. We do expect all of them to work together. And some of them have been shipped. They're in Malaysia. Some are in the way of shipping, but we're holding the date for getting the samples to customers, although some of the zones have pushed a little bit.

[Ajay Marathe, executive]

Yes. Just to add to that, yes, feeling fairly -- I don't know if you guys can hear me okay or not, but I'm here calling in from Fab-2. Feeling pretty confident about how the machines are behaving. And I think we shared some of the data as well, early data on FAT during -- in the podcast. So yes, feeling confident that Q2, we'll definitely get samples out from the Agility Line here in Malaysia.

[Operator]

Our next question comes from Jed Dorsheimer with William Blair.

[Jed Dorsheimer, analyst]

Raj, you've talked about some of the performance trade-offs between EX-1, EX-1M and EX-2. I was wondering, how should we think about the value creation in terms of some of those trade-offs. And what I'm really trying to get to is ASP differences between the different products. And then I have a follow-up.

[Raj Talluri, executive]

Yes. Jed, it's really based on the end markets. I think our view is that when you go into things like smartphones, [ where they're ] go into laptops, you've got to get to 800 cycles, 1,000 cycles, in that range. You think about it, if you have a phone, you're going to charge it every day, so you're looking at 350 charges, discharge cycles a year. Let's say, you keep the phone for 2.5 to 3 years, you're quickly at the 1,000 range, right? So you pretty much have to be able to do that. If you look at a wearable or maybe some of the IoT devices, you might keep it for lesser number of years. Maybe you don't charge it every day. So you can go get away with less number of cycles, right? When we decided to go after smartphones as a big market and then laptops, 1,000 cycles -- 800 cycles to 1,000 cycles became a must, and we aimed at 1,000 as a target. If some customers want to take 800-cycle device, that's good. We can do that, but we set the goal aggressively.Now, the ASP is going to depend upon what they value most, right? Ultimately, there is must-meet requirements, which is fast charge, which is cycle life, which is not swell at high temperatures when you store the battery, safety and so on. Once you meet those, the amount of ED we provide on top of that is what's going to change the ASP premium that we command. In some other markets, maybe cycle life is not that important. We can index more on ED, and then we can get a premium for that. So it really depends on the end market. Some are must-have requirements, and some are requirements that once you do them, you can get more premium for higher ED.

[Jed Dorsheimer, analyst]

As a follow-up, I know on wearables, we've talked about Apple Watch in terms of the value of the additional battery life is not as great as that of a phone. But I'm curious, when we look at Apple Vision or when we look at something that only has 2 hours of battery life certainly gating the adoption of that product, how do you think about the value in terms of the -- and therefore, the gating function of the battery to kind of help those markets open up to larger volumes?

[Raj Talluri, executive]

Yes, absolutely. That is -- there are more and more applications like that coming out that absolutely need much higher energy density. And I am one of those proud owners of Apple Vision Pro. I love the device, and I hate the 2-hour battery life. It's -- the single biggest problem with the device is the battery life. So -- but it's a phenomenal device. And I think the reason the device is so great is because of the performance that's in there with the memories and the processors and the displays. And there's an IMAX app, I tried on it, and it just feels like you're in a movie, in an IMAX theater, but the battery goes down pretty fast. So I think the ASP premium is there in those markets because that's, I think, all told, $4,000 product, and people will be willing to -- I mean, what if you could double that battery life? That'd be awesome. So I think a lot -- I mean, I actually think that is just the first of the many products that are coming. And this is what I've mentioned when I first came to this job is that the performance and the end user experience that great processors, great memory devices, great displays, great cameras can deliver is huge. We haven't seen how good that can be. And now, we are seeing with the early products coming out. There will be a lot more like that, that will come out. And you'll see that to deliver the experience that these advances in chips and cameras and memories as really delivered, you can't really realize them until you have a better battery. And that's why I think that once we produce this battery, there will be a lot of opportunity for a differentiated ASP.

Our next question comes from Derek Soderberg with Cantor.

[Derek Soderberg, analyst]

I wanted to start with, on the slide deck, it looks like you guys have the goal of multiple smartphone launches in 2025. I'm wondering what you're going to need from a production capacity standpoint to achieve this. Can you do that with a single line? Do you need 2 lines? Any detail on that would be great.

[Raj Talluri, executive]

Yes. So I think it's important for me to like explain how the process works. I know I get asked this question a lot. So if you think about where we are in our journey, we now have a recipe with EX-1M that we feel pretty good about that actually meets the requirements of the market. We have our factory coming up now, and we feel pretty good that we'll be able to get some samples in April from that. And so, what happens next, right? We're going to give these to our customers. They're going to test them, and they're going to give us some feedback, and they're going to give us feedback on maybe some optimization on dimensions of how big the battery should be and so on. We're going to make those changes because we have an Agility Line that can actually do different size batteries. We're going to give those back to them, and they're going to test them again. And like I said, we are sampling multiple cellphone customers. And when you do that, typically, it's 9 months to 12 months, as I mentioned, on how long it takes them to qualify the battery because you remember, we're talking about 1,000 cycle battery, which means they've got to charge-discharge for 1,000 cycles to make sure it's okay. That will take some -- that will take the 9 months to 12 months. And then, we get designed into, if things go really well, maybe multiple models. They'll start with one model. If things go really well, maybe you'll have multiple OEMs. So the amount of volume that we need is going to depend upon how these qualification cycles go. And that's going to get how much capacity we need to build. We do have one line now that can produce, as I mentioned, around 9 million batteries or so a year. And we're going to be watching those customer qualifications closely and making decisions on how to make sure we have enough capacity based on how the design wins are going. And that's something that, as this year goes through, we'll continue to update you on that.

[Derek Soderberg, analyst]

Got it. And as my follow-up, Ajay, you spoke a bit about yield on the last podcast, and you mentioned a bit about throughput just now on the video. From your perspective, how is the equipment as a whole? I know you guys did a bunch of proof-of-concept tests. Just curious your thoughts and confidence level around everything together, hitting sort of that 1,350 UPH metric and share any incremental details on how throughput is tracking as well.

[Ajay Marathe, executive]

Sure. Yes, Good question. The yields -- I mean, as a part of the FAT, as Raj mentioned, we are doing some rigorous -- just take one example, laser, for example, there's about 25, 26 critical-to-quality parameters that we track. They're doing that in FAT, making sure the CPE and the CPKs of that is at good -- more than 1.0 CPK levels. We'll further fine- tune that to 1.33. But yes, fairly -- looking fairly good that we are -- when we clear the FAT that the yield on certain critical processes throughout the line, from our learnings in Fab-1, will not only hold but will start at the right time and the right place. So yields, kind of looking more and more confidence we are gaining, actually, as we finish the FAT. The POCs helped us design the equipment right. Now, the FATs are helping us ensuring that the yields are going to hold. And then, the SAT, which is going to happen here, some of it has already started. In fact, the machines behind me are going through SAT right now, are going to assure that the fine-tuning will help us get the yield even at a better place, right? So that yield -- UPH-wise, Zone 2 and 3 is really the battery line, which runs at -- or we still run at 1,350 UPH. Zone 1 and 4, we are tuning it [ too as a farm ], and we'll do the 1,350, but we can keep on adding to that to make sure it is debottlenecked. So 1 and 4 are farms. They will be adjusted to 1,350. 2 and 3 are the ones which are kind of locked in. And we are feeling good about both these things.

Our next question comes from Anthony Stoss with Craig-Hallum.

[Anthony Stoss, analyst]

Raj, a lot of my questions were asked, but maybe now that you've had Routejade under your belt for a while, can you update us what you've learned from Routejade? And then, also just to get Farhan in the action here, just your view on OpEx for March and where OpEx trends through the rest of the year.

[Raj Talluri, executive]

Yes, Routejade, I visited the factory, I think, a few months ago. We are super thrilled by the acquisition. It's really phenomenal. This company has been making production batteries shipping for over 20 years. And it's an expertise that really complements what we have in the company. They understand battery manufacturing. They understand safety. They understand different end markets. And more importantly, their coating expertise is phenomenal. So the thing I want to mention is that when you coat a roll properly to the right specifications, it makes it much easier to cut it on the laser and to stack it. So it's very important you own the incoming material quality and specification, and which is one of the problems we had when we were running in Gen1 that we were relying on third-party toll coaters who weren't that motivated to -- really to coat it like how we wanted it because you got to remember, we don't just take rolls and make them jelly rolls like other people that they used to supply to. We cut them with lasers, so they're very different, and we stack them. So it's -- I realized when I came in last year that it was a key piece of the manufacturing process we absolutely needed. And now, we are using that capacity to -- even for Ajay to do his FAT and SAT and so on. So when that material comes out, we're able to quickly go back and forth between making sure its coating is right and the laser cutting is right and so on. So it's like an end-to-end optimization.The second thing we found is that the team at Routejade has 2 things that they do really well in addition to the things I mentioned. They know how to make high-current batteries. So these are batteries that can actually propel things like run electric motors, run drones, run military applications. That's a very unique value proposition that actually we are able to now looking at how to extend the customer breadth there. And the second one is they can make odd-shape batteries. They can make donut batteries. They can make different shape batteries because of their ability to -- the way they laminate and the way they stack batteries. So we have some customer base that actually overlaps that we're able to now go in and also present some of the silicon anode-based batteries, and -- but some customer base, where we are able to sell Routejade-made graphite batteries. And so, we will continue to spend more time and grow the revenue of that company that we acquired. It's one team now. So super exciting, and it's very fortunate to us that we were able to get the acquisition done quickly.

[Farhan Ahmad, executive]

So, yes, touching on the OpEx side, from Q4 to Q1, it should be similar level. From Q1 to Q2, there should be a decline because of the $18.5 million of the depreciation that we talked about and also because of the actions that we have taken in Fremont. Some of those benefits will come through, so you should get additional low-single digit kind of a benefit like that should also decline. And then, for the year after that, we should be holding it steady, maybe go up slightly towards the end of the year. For the full year, like if you look at the EBITDA of the company, you should kind of think of it for the full year, very similar to what we had in '23, and fairly steady through the year as well.

[Anthony Stoss, analyst]

Very good. Best of luck.

[Operator]

Our next question comes from Gabe Daoud with Cowen.

[Gabriel Daoud, analyst]

Raj, I was hoping we can maybe just go back to EX-1M and EX-2M. There's already been a lot of discussion around it. But just curious if you could maybe quantify what the energy density targets are for each and just how that compares to leading-edge mobile phones in the market today.

[Raj Talluri, executive]

Yes. We haven't put out exactly a precise target, mainly because we are making the right, I would say, trade-off between energy density, cycle life, fast charge, safety, and then also the fast charge. And that's very important. It will definitely be higher than what is in the market today. I think we put some slide -- we put in our investor deck what we expect to get to on EX-2M. Where exactly EX-1M will land is a decision we're going to make together with our customers. As I mentioned, it's not just one parameter that drives -- doesn't drive design wins. It's a sum total of all those 5 parameters that we need to be thinking about, and that's where we are focused on. It will definitely improve over what's in the market for sure. We just want to make sure that we did it right with our customers because they also are involved now in the trade-off that they actually want to make to get the right battery in time.

[Gabriel Daoud, analyst]

Okay. Got it. That makes sense. Certainly, a lot of parameters you need to solve for depending on the customer. Okay. Then, just as a follow-up, very clear on when EX-1M and EX-2M are expected to be shipped for customers to sample. But when will the cells actually be coming off the high-volume manufacturing line? I guess I'd imagine that some customers would want to see cells off of that line as part of the qualification process, too. Is that within the 9-month to 12-month window that you talked about?

[Raj Talluri, executive]

The short answer is, yes. The good news is, our Agility Line and the high-volume manufacturing line use the exact same modules. So in that sense, it's -- and also from the same place. They're both in Malaysia in the same factory that you see where Ajay is right now. So in that sense there's a lot of similarities. So our expectation is that once they get samples from one, moving to the other one, it should be a short cycle time call because they're really the same machines. It's just the scale is different, which is actually a very key part of our strategy to reduce that cycle time. But ultimately, look, we'll get them the samples, but the exact qualification time, like I said, is going to depend upon phone-level qualification. And when I talk to my customers, they basically tell me, look, Raj, depending upon how good your first samples are and where we put it, it's anywhere between 9 months and 12 months. And that's kind of what we are looking -- working towards.

[Operator]

Our next question comes from Ananda Baruah with Loop Capital Markets.

[Ananda Baruah, analyst]

I guess, the first one maybe is for Ajay, if you're still online, Ajay. Just to the earlier question about yields, is there a useful way to think about where you guys think yields in Fab-2 will be in April-May when you start putting out legitimate samples? And then, are there yield targets through the year as well? And I guess, I have a quick follow-up, like what's the value of the yield targets that you guys have as well? And I have a quick follow-up after that.

[Ajay Marathe, executive]

Good question, Ananda. So all the learnings and all the root cause analysis that we have done on the Gen1 yields for the last 4 years that we have been sort of ramping up -- ratcheting it up slowly, where we ended in Gen1, that's where we will begin in Gen2. All the learnings have been [ played in ] into the Gen2 equipment and the design. And what Gen1 could not provide, we have made sure the design accommodated that here in Gen2. So we'll start there. Pretty decent yields. Mostly all CPK windows are the process driven, more than 1.1, 1.2 CPK kind of thing for every process set. There are several yield points during the line. So you can multiply those and you'll get a pretty decent yield. But then immediately after that, all the fine-tuning and within the 3 quarters, we are going to deliver upwards of 90%-plus yield in the Gen2 line. That's how we are thinking, and that's how we are planning actually. And the FAT, SATs are supporting that.

[Ananda Baruah, analyst]

So, that's super helpful. Yes, super helpful. And I guess, the follow-up is -- maybe this is for Raj and Farhan as well. Like what -- in terms of your margin model, right, so let's say you hit the 90%-plus yield targets that Ajay just spoke to. What -- is that at scale margins? Is that in the margin model? I guess, where are you in the margin model when you start shipping kind of volumes at those kinds of yields into initial customers and production?

[Raj Talluri, executive]

Yes, that's the right number. That's the right number to think about. I mean, look, this is consumer products, right? We've all done this with the processors and memories, and Ajay and I have done it for, I don't know, how many decades. But you got to get to 90%-plus yields. High-90s is where we really need to get to. But we have premiums that we believe we can command because of what we're able to provide, and that will help us for a while. But ultimately, we got to get to those numbers. And I think the -- we factored that in into how the FAT is done and SAT is done. And that's kind of the important part here is that the acceptance criteria for the machines is to be running at that level of CPK so that when we get them, we string them all together, it shouldn't take -- hopefully, it shouldn't take a lot of optimization to get to target yields. So that's kind of what we are planning.

[Operator]

Our next question comes from Chris Souther with B.Riley.

[Christopher Souther, analyst]

I just wanted to follow up on -- you talked about a 9 months to 12 months to qualify for some of these wins. Is that after EX-1M is already in customers' hands? Or are we already in that like 9 months to 12 months with some of the samples of prior cells you've supplied to some of these customers? And then, should we think about -- is there kind of a lead time out between design-in and kind of a launch that's a good kind of rough time frame we should expect? I just wanted to kind of get a little bit more on the cadence there.

[Raj Talluri, executive]

Yes, that is what after we deliver the samples from -- in April from our factory, right? What we have done previously has really helped them understand our technology and how it works and so on. But the product that's actually targeted to go into the cell phone is a 1,000 cycles, fast charging product, which is one we want to sample in April, and that's when you can think of the clock starting. Now, we'll -- typically, my experience in these kind of things is that we will get to a model that we're going to be in -- there'll be technology evaluation where they're just evaluating the battery in isolation in terms of the tests and so on. Then they'll actually pass that. Then they'll actually put it in an actual phone model, and that will go on for some time. And then, the precise phone it will go into is the one that happens next. So that's the total period of 9 months to 12 months. The actual design win of what model we are on will come just a few months before high volume. Typically, it doesn't -- they don't decide way ahead. But the good news is once you pass the technology qualification, once you're in their vendor list, subsequent models can come much faster because you're now inside, right? And that's what my experience has been previously with memories and processors. The first one takes a little longer. Once we get in, follow-on models can come faster.

[Christopher Souther, analyst]

Understood. And then, maybe just on the Routejade contribution in the fourth quarter, can you update us on what the run rate is for that legacy business? It seemed a little bit stronger than I'm expecting at least.

[Farhan Ahmad, executive]

Yes. I can talk about that. So in the fourth quarter, Routejade business tends to be stronger. There's normally a seasonality associated with it. So the -- for the year, the seasonality is that the second quarter is kind of the low point. The fourth quarter is the strong point, generally speaking. This year, in '23, what we saw was that there was a bunch of business that was at the end of the year and beginning of '243, so end of '23, beginning of '24, and a lot of that got shipped in '23. So, that was a factor why the revenue came in stronger, and also like quarter-on-quarter decline, also it contributed to it. So generally speaking, for the first 3 quarters, you should think of it as about $18 million annualized run rate, and then fourth quarter stronger, and with the fourth quarter of '23 being somewhat exceptionally stronger.

[Operator]

Our next question comes from Tim Moore with EF Hutton.

[Timothy Moore, analyst]

Most of my questions were already answered. But regarding -- you mentioned the 90% yield goal commentary 2 questions ago. Can you maybe give us a rough better sense, and we won't hold you to it, of the timing road map maybe for potential revenues run rate, when you look out to maybe the December quarter or the March quarter next year from the Fab-2 sample production, if that goes pretty well? Any rough thoughts on maybe what the revenue tied to that could be a year from now quarterly?

[Farhan Ahmad, executive]

No, I was just saying that we're guiding 1 quarter at a time. And so, we'll get to it when we get to it. But we kind of talked about the timing of the production ramp and we talked about -- we gave you some good color on that. And we have given like '25 that we will be in smartphones. And so, you will have a revenue ramp associated to that. I don't know, Raj...

[Raj Talluri, executive]

Absolutely. Look, we're going to sample products from our Fab-2 in April. And we -- hopefully, there will be some IoT-type customers that can go to production earlier in '24, but the smartphone ones will really be in '25. So I think that's just the way you guys should be thinking about this. And again, super excited by the technology and the acceptance of the customer base. Once we qualify, it's just going to be a lot more fun.

[Timothy Moore, analyst]

That's good to hear. I think you were pretty clear on the 2025 timing for the smartphones, but the IoT, it could be pretty promising maybe towards the end of the year. And the other question I had just on smartphones, [ Ahmad ] mentioned it was a sum total of parameters and there's trade- offs. If you get asked during qualifications and maybe pilots, do you think you could get asked to do an exclusive contract for a major OEM customer? Can you do a unique specification exclusively for them? Or is that something you won't consider?

[Raj Talluri, executive]

Yes. Look, it's just a business case, right? So if there's guaranteed volumes and good ASP, we're totally open to it. But the way -- the nature of this business is that -- what I expect to happen is that we'll probably sign some joint development agreements or something like that, and then they'll talk about what size battery they want, what size battery we make, what time is the yield, and that's how these things go typically, from my experience. But in some way, it will become a little bit exclusive because of the shape of the battery, not the technology itself, right?

[Timothy Moore, analyst]

Okay. That makes sense. Well, good luck with the April sampling.

[Operator]

There are no further questions at this time. With that, I'd like to turn it over to Dr. Raj Talluri for closing remarks.

[Raj Talluri, executive]

Yes. Thank you all. Been a really great year and '23 recap. Super excited by where we are in '24. So look forward to talking to you guys next quarter. Thank you for all your interest.
