Thank you, Leslie. Good afternoon, everyone, and thanks for joining our first earnings conference call as a public company. This year is off to a great start with Astera Labs seeing strong and continued momentum along with the successful execution of our IPO in March. First and foremost, I would like to thank our investors, customers, partners, suppliers and employees for their steadfast support over the past six years. We have built Astera Labs from the ground up to address the connectivity bottlenecks to unlock the full potential of AI in the cloud. With your help, we've been able to scale the company and deliver innovative technology solutions to the leading hyperscalers and AI platform providers worldwide. But our work is only just beginning. We are supporting the accelerated pace of AI infrastructure deployments with leading hyperscalers by developing new product categories, while also exploring new market segments. Looking at industry reports over the past several weeks, it is clear that we remain in the early stages of a transformative investment cycle by our customers to build out the next generation of infrastructure that is needed to support their AI roadmaps. According to recent earning reports, on a consolidated basis, CapEx spend during the first quarter for the four largest U.S. hyperscalers grew by roughly 45% year-on-year to nearly $50 billion. Qualitative commentary implies continued quarterly growth in CapEx for this group through the balance of the year. This is truly an exciting time for technology innovators within the cloud and AI infrastructure market, and we believe Astera Labs is well position to benefit from these growing investment trends. Against the strong industry backdrop, Astera Labs delivered strong Q1 results with record revenue, strong non-GAAP operating margin, positive operating cash flows, while also introducing two new products. Our revenue in…

Thanks, Jitendra, and good afternoon, everyone. Astera Labs is well positioned to demonstrate long-term growth through a combination of three factors. One, we have a strong secular tailwinds with increased AI infrastructure investment. Two, the next generation of products within existing product lines are gaining traction. And third, the introduction of new product lines. Over the past three months, we announced two new and significant products that play an important role in enabling next generation AI platforms and provide incremental revenue opportunities as early as the second half of 2024. First, we expanded our widely deployed field proven Aries Smart DSP Retimers portfolio with the introduction and public demonstration of our Aries 6 PCIe Retimer that delivers robust, low power PCIe Gen 6 and CXL 3 connectivity between next generation GPUs, AI accelerators, CPUs, NICs, and CXL memory controllers. Aries 6 is the third generation of our PCIe Smart Retimer portfolio and provides the bandwidth required to support data intensive AI workloads while maximizing utilization of next generation GPUs operating at 64 gigabit per second per link. Fully compatible with our field deployed COSMOS software suite, Aries 6 incorporates the tribal knowledge we have acquired over the past four years by partnering and enabling hyperscadeless to deploy AI infrastructure in the cloud. Aries 6 also enables the seamless upgrade path from current PCIe Gen 5 based platforms to next generation PCIe Gen 6 based platforms for our customers. With Aries 6, we demonstrated industry's lowest power at 11 watts at Gen 6 in full 16 lane configuration running at 64 gigabit per second per lane, significantly lower than our competitors and even lower than our own Aries Gen 5 Retimer. Through collaboration with leading providers of GPUs and CPUs such as AMD, ARM, Intel, and NVIDIA, Aries 6 is being…

Thanks, Sanjay, and thanks to everyone for joining. This overview of our Q1 financial results and Q2 guidance will be on a non-GAAP basis. The primary difference in Astera Labs non-GAAP metrics is stock-based compensation and the related income tax effects. Please refer to today's press release available on the Investor Relations section of our website for more details on both our GAAP and non-GAAP Q2 financial outlook as well as a reconciliation of our GAAP to non-GAAP financial measures presented on this call. For Q1 of 2024, Astera Labs delivered record quarterly revenue of $65.3 million which was up 29% versus the previous quarter and 269% higher than the revenue in Q1 of 2023. During the quarter, we shipped products to all the major hyperscalers and AI accelerator manufacturers. We recognized revenues across all three of our product families during the quarter with Aries products being the largest contributor. Aries enjoyed solid momentum in AI based platforms as customers continue to introduce and ramp their PCIe Gen 5 capable AI systems, along with overall strong unit growth with the industry's growing investment in generative AI. Also, we continue to make good progress with our Taurus and Leo product lines, which are in the early stages of revenue contribution. In Q1, Taurus revenues were primarily shipping into 200 gig Ethernet based systems, and we expect Taurus revenues to sequentially track higher as we progress through 2024, as we also begin to ship into 400 gig Ethernet based systems. Q1 Leo revenues were largely from customers purchasing pre-products volumes for their development of their next generation CXL capable compute platforms expected to launch late this year with the next server CPU refresh cycle. Q1 non-GAAP gross margins was 78.2% and was up 90 basis points compared with 77.3% in Q4 2023.…

[Operator Instructions] Our first question will come from the line of Harlan Sur with JPMorgan.

Good afternoon and congratulations on the strong results and guidance post your Q1 as a public company. As you guys mentioned, many new AI XPU programs coming to the market, GPU, ASIC AI chip programs, accelerators. In terms of total XPU shipments this year, I think only half is going to be NVIDIA based, so it is starting to broaden out. The good news is, obviously, the Astera team has exposure to all of these XPU programs. It does seem that the pace of deploying these XPU platforms has accelerated even over the past few months. So how much of the strong results and guidance is due to this acceleration, broadening in customer deployments? How much is more just kind of higher content of Retimers versus your prior expectations? And then do you guys see the strong momentum continuing to the second half of this year?

Thanks, Harlan. This is Mike. We started shipping into AI servers really in Q3 of last year, so it's just in the early innings. Lot of our customers have not fully deployed their AI system. So we're seeing incremental growth just from adding on the different platforms that we have design wins in. But it's on a, in a backdrop where there's clearly growing investment in AIs as well as overall unit growth is also playing out. As we look out to the balance of this year, there's still a lot of programs that have not ramped yet. So we have the highest confidence that the Gen 5 Aries platform has a lot of growth ahead of it, and that continues into 2025 as well.

And as you mentioned, there's been a lot of focus on next gen PCIe Gen 6 platforms, right, obviously, with the rollout of NVIDIA's Blackwell based platform? And, obviously, with any market that is viewed of as fast growing, you are going to attract competitors. We have seen some announcing by competitors. We know most of the Gen 5 design wins have already been locked up by the Astera team. You've been working with customers, as you mentioned, on Gen 6, for some time now. Maybe how do you compare the customer engagement momentum on Gen 6 versus the same period back when you were working with customers on Gen 5?

Good question, Harlan. This is Sanjay here. Let me take that. So like you correctly said, Gen 5 is still a lot of legs on it. Let's be very clear on that. Like Mike noted, we do have platforms that are still ramping and still to come. So to that standpoint, we do expect Gen 5 to be with us for some time. And in terms of Gen 6, again, it's driven by the pace of innovation that's happening on the AI side. There is, as you probably know, there's GPUs are not fully utilized. Some reports put it at around 50%. So there's still a lot of growth in terms of connectivity, which is essentially holding it back, right, meaning there's a pace and a need to adopt faster speeds and links. So, with NVIDIA announcing their Blackwell platform, those are the first set of GPUs that have Gen 6 on that. So for that standpoint, we do expect some of those deployments to happen in 2025. But in general, others are not far behind based upon public information that's out there. So, we do expect the cycle time for Gen 6 adoption to perhaps be a little bit shorter than Gen 5, especially on the AI, server application, more so than the general purpose compute, which is still going to be lagging when it comes to PCIe Gen 6 adoption.

Your next question will come from the line of Joe Moore with Morgan Stanley.

Following on from that, can you talk about PCI Gen 5 in general purpose servers? It seems like if I look at the CPU penetration of Gen 5, we're still at a pretty early stage. Do you see growth from general purpose and what are the applications driving that?

Absolutely. And primarily on the general purpose compute, the main places where the PCIe timer gets used tends to be on the storage connectivity where you have SSDs that are on the back of the server. So to that standpoint, again, it's, there are two things that have been holding it back or three things perhaps. One is just the focus on AI. I mean, most of dollars are going to the AI server application compared to general compute. The second thing is just the ecosystem readiness for Gen 5, primarily on the SSD side, which is starting to evolve with many of the major SSD NVMe players providing or ramping up on Gen 5 based, NVMe drives. The third one really has been the CPU platforms. If you think about it both from Intel and AMD, they're all on the cusp of introducing their next significant platform, whether it is Granite Rapids for Intel or Turin from AMD. So that is expected to drive the introduction of new platform. And if you combine that with the SSDs being ready for Gen 5 and based on the design wins that we already have, you can expect that those things would be a contributing factor as dollars start flowing back into the compute side, general purpose compute side.

And for my follow-up, you just mentioned Granite Rapids and Turin, which are the first kind of volume platform supporting CXL 2. What are you hearing in terms of the CPUs will be out, but what will be the initial adoption and how quickly do you think that technology can roll out in 2025?

Yes. Let me start off by saying, CXL, every hyperscaler is in some shape or form evaluating and working with the technology. So it's well and alive. I think where the focus really has been in terms of CXL is on the memory expansion use case, specifically for CPUs. And the expansion could be for reasons like adding more memory for large database applications, more capacity memory. And the second use case, of course, is for more memory bandwidth, which are for HPC type of applications. So the thing that's been holding back is the availability of CPUs that support CXL at a production quality level. That will change with Granite Rapids and Turin being available. So at this point, what we can say is that we've been providing chips for quite some time. We've been in preproduction and supported the various different evaluation POC type of activities that have happened with our hyperscaler customers. So, to that standpoint, we do expect revenue to start coming in 2025 from memory expansion use case for CXL.

Your next question will come from the line of Tore Svanberg with Stifel.

Yes. Thank you. And let me add my congratulations. My first question is on Gen 6 PCI. So Sanjay, you just mentioned that the design in cycle is going to be shorter than Gen 5 now. Since its backwards compatible for your Gen 5 and especially given the COSMOS software platform, should we assume that you will basically retain most of those sockets that you already had in Gen 5 and then obviously some new ones as well for Gen 6?

That's the goal for the company. We have the COSMOS software and like I noted, PCI Express is one of those protocols which, unlike Ethernet, tends to be a little messy, meaning it's something that's been around for a long time. It's a great technology, but it also requires a lot of handholding. And for us, what has happened is being in the customers' platforms, bringing up systems that ramp up to millions of devices has allowed us to understand what are the nuances, what works, what doesn't work, how do you make the link perform at the highest rate. So that tribal knowledge is something that we've captured within the COSMOS software that we built running both on our chips as well as customers' platforms. So we do expect that as Gen 6 starts to materialize, lot of those learnings will be carried over. Now you're right that there's been a lot of competition that has come in as well. But we believe that when it comes to competition, they could have a similar product like us. But no matter what, there is a full time that's essential when it comes to connectivity type of chips, just given the interoperation and getting the kings out and so on. Meaning you could have a perfect chip yet have a failing system. The reason for that is the complexity of the system and how PCI Express standard is defined. So to that standpoint, I agree with what you said in the sense that we have the leading position now in the Retimer market for PCIe and we expect to build on that both with the new features we have added in PCIe Gen 6 or the AEC product line and also the tribal knowledge that we have built by working with our partners over the last three, four years.

That's a great perspective. And as my follow-up, I had a question on AEC. It sounds like that business is going to start ramping late this year. First of all, is that with multiple cable partners? And then related to that, are you the only company today that have, an AEC at 7 meters?

I don't know about the only, customer. I would probably request maybe you need to do some research on it on where the competition is. But from a Retimer standpoint, which goes on this, we do have a leading position. So based on that, I would imagine that we are the main provider here, both based on that and the customer traction that we're seeing. So, this one is an interesting use case. So far, PCI Express, as you know, was defined to be inside the server. But what is happening now, and this is why we're excited about PCIe, AECs, is that now we are opening up a new front in terms of clustering GPUs, meaning interconnecting accelerators. That is where the AECs will play, and that is a new opportunity that goes along with the Ethernet AECs that we already provide, which are also used for interconnecting GPUs on the backend network. So, overall, we do believe that combining our PCIe AEC solution and Ethernet AEC solution, we're well set for some of these evolving trends. And our revenue we expect to start coming in for the latter half of this year. And on PCIe, again, we do believe we are the only one just to make sure I clarify what I initially said, just that I don't know if there is someone else talking about it that's not yet in the public domain.

Your next question will come from the line of Blayne Curtis with Jefferies.

Maybe first one for you, Jitendra. Just curious, you mentioned the right architectures, I think, Harlan asked on it. I was just kind of curious about obviously, you have a lead customer and it's a lot of CPU to GPU connections. That's the nature of the market who has the volume. But I'm curious you mentioned back, the backend fabrics a bunch. Kind of curious is that still conceptual? Are you seeing designs for it? And maybe just talk about the widening out of just applications for what the Retimers are being used for?

Great question. So, there are many applications where we use the Retimers. Of course, we are most known for the connectivity from the GPU to the head node. That is where a lot of the deployments are happening. But these new applications also speak to how rapidly the AI systems are evolving. Every few months, we see a new AI platform come up and that opens up additional opportunities for us. And one of those is to cluster GPUs together. There are two main protocols that are used in addition to NVLink, of course, which are used to cluster GPUs that is PCI Express and Ethernet. And as Sanjay just mentioned, we now have solutions available to interconnect GPUs together, whether they are for PCI Express and/or Ethernet. Specifically, in the case of PCI Express, some of our customers who want to use PCI Express for clustering GPUs together are now able to do so using our PCI Express Retimers, which are offered in the form of an active electrical cable. So this business is going to be in addition to the sustaining business that we have today in connecting GPUs to head nodes. Now we are connecting GPUs together in a cluster. And as you know, these are very intense, very dense mesh connections. So they can grow very, very rapidly. So we are very excited about where this will grow and starting with some revenue contributions later this year.

And then maybe a question for Mike. The gross margin remained quite high. You said it was mix. I mean, maybe you're just being kind of conservative with the IPO, but I was just kind of curious did the mix come in? I mean, I think it's mostly Retimers. I know as the other products start to ramp that will be the headwind. So, I'm just kind of, how do you think about the rest of the year? Should we kind of just have it kind of come down with mix gradually as those new products ramp off this 70% that you're guiding to?

Yes. So just to remind everybody, our standalone ICs carry a pretty high margin relative to our hardware solutions. So when the mix gets a little more balanced with hardware versus standalone ICs, we're expecting our long-term gross margins to 10% to 70%. In Q1, we were heavily weighted to standalone ICs, very favorable mix and that's how we enjoyed the strong gross margins. As we go through the balance of this year and into next year, we will see an increasing mix of our modules and also add in cards for CXL as well. So, we think we'll have a gradual trend down towards a long-term model over time as that mix changes.

Your next question will come from the line of Thomas O'Malley with Barclays.

Mike, I just wanted to ask, I know you may not be giving segment details specifically, but could you talk about what you're able to, what contributed to the revenue in the quarter? And then looking out into June, could you talk about from a revenue mix perspective, maybe some sequential help on what's growing? Obviously, the non-ICs business is growing just given the fact that gross margins are pressured a bit, but just any color on the segments would be helpful to start?

Sure. So as I mentioned, we started shipping into AI server platforms in volume in Q3 and a lot of our customers are still in the ramp mode to the extent we've been shipping for the past couple of quarters. But there's still a lot of designs that haven't even begun to ramp. So, we're still in the early phases that if you look out in time, we see the Gen 5 piece of it in AI continue to grow into next year as well. So as you look into Q2, the growth that we're guiding to is still largely driven by the Aries Gen 5 deployment in AI servers both for existing platforms with increased unit volumes, but also the new customers begin their ramps as well.

And then just a broader one. In talking with NVIDIA, they're referencing your GP-200 architecture becoming a bigger percent of the mix, NVLink 72 being more of the deployments that hyperscalers are taking. When you look at the Hopper architecture versus the Blackwell architecture and their NV72 platform, where they're using NVLink amongst their GPUs, can you talk about the puts and takes when it comes to your retiming product? Do you see an attach rate that's any different than the current generation?

Let me take that. Great question. First, let me say that we are just at the beginning phases of AI. We will continue to see new architectures being produced by AI platform providers at a very rapid pace, just match up with the growth in AI models. And on top of that, we'll see innovative ways that hyperscalers will deploy these platforms in their cloud. So as these architectures evolve, so do the connectivity challenges. Some challenges are going to be incremental and some are going to be completely new. And so what we believe is given the increasing speeds, increasing complexities with these new platforms, we do expect our dollar content per AS platform to increase over time. We see these developments providing us good tailwinds going here into the future. So now to your question about the GP-200 specifically, well, first of all, we cannot speak about specific customer architectures. But here is something that is very clear to see. As the AI platform providers produce these new architectures, the hyperscalers will choose different form factors to deploy them. And in that way, no two clouds are the same. Each hyperscaler has a unique requirement, unique constraint to deploy these AI platforms and we are working with all of them to enable these deployments. This combination of new platforms and very cloud specific deployment strategies, it presents great opportunities for our PCIe connectivity portfolio. And to that point, as Sanjay mentioned, we announced the sampling of our Gen 6 Retimer during GTC. If you look at our press release, you will see that broad support from AI platform providers. And to this day, to the best of our knowledge, we are still the only one sampling agnostic solution. So, on the whole, given the fact that speeds are increasing, complexity is increasing, in fact the pace of innovation is going up as well, these all play to our strengths and we have customers coming to us for new approaches to solve these problems. So we feel very good about the potential to grow our PCIe connectivity business.

Your next question will come from the line of Quinn Bolton with Needham.

I just wanted to follow-up on the use of PCI Express in the GPU to GPU backend networks. I think that's something historically you had excluded from your TAM, but it looks like it's becoming an opportunity here and starts to ramp in the second half of this year. Wondering if you could just talk about the breadth of some of the custom AI accelerators that are choosing PCI Express as their interconnect over, say, Ethernet? And then I've got a follow-up.

Again, great question. So just to kind of follow-up the response that we provided before. There are two, three dominant protocols that are used to cluster GPUs together. The one that's most well known, of course, is NVLink, which is what NVIDIA uses and is the proprietary interface. The other two are Ethernet and PCI Express. We do see some of our customers using PCI Express and I think it's not appropriate to say who, but certainly PCI Express is a fairly common protocol. It is the one that's natively found on all GPUs and CPUs and then others data center components. Ethernet is also very popular and to the extent that a particular customer chooses to use Ethernet or PCI Express, we are able to support them both with our solutions, the Aries PCIe Retimer family as well as the Taurus Ethernet Retimer family. We do expect these two to make meaningful contributions to our revenue, as I mentioned starting with the end of this year and then of course continuing into next year.

And my second question is you guys have talked about introduction of new products as new TAM expansion activity and I'm not going to ask you to introduce them today. But just in terms of timing as we think out, are these new products timeline sort of introduction later this year or 2025 with revenue ramp in 2026? Is that the general framework investors should be thinking about the new products that you've discussed?

Again, I think we, as a company don't talk about unreleased products, the timing of it. But what I can share with you is the following. First, we've been very fortunate to be in the central seat of AI deployment and enjoy a great relationship with the hyperscalers and AI platform providers. So we get to see a lot, we get to hear a lot in terms of some of the requirements. So clearly, we are going to be developing products that address the bottlenecks, whether it is on the data side, network side or on the memory side. So we are working on several products, as you can imagine, that would all be developed ground up for AI infrastructure and enable connectivity solutions that will deploy the AI application sooner. There is a lot going on, a lot of new infrastructure, a lot of new GPU announcements, CPU announcement. So, you can imagine given the pace of this market and the changes that are upcoming, we do anticipate that this will all start having meaningful impact and incremental revenue impact to our business.

Your next question will come from the line of Ross Seymore with Deutsche Bank.

I wanted to go into the ASIC versus GPU side of things. As ASIC start to penetrate this market to certain degrees, how does that change, if any, the Retimer, TAM that you would have? And I guess even the competitive dynamic in that equation considering one of the biggest ASICs suppliers is also an aspiring competitor of yours?

So, great question again. Let me just refer back to what I said, which is we will see more and more different solutions come to the market to address the evolving AI requirements. Some of them are going to be GPUs from the kind of known AI providers like NVIDIA, AMD and others. And some others will be custom built ASICs that are built typically by hyperscalers, whether they are AWS or Microsoft or Google and others. And the requirements for these two systems are common in some ways, but they do differ. For example, what particular type of backend connectivity they use and exactly what are the ins and outs that are going to each of these chips. The good news is with the breadth of portfolio that we have and the close engagement with the several ASIC providers as well as the GPU providers, we understand the challenges of these systems very well. And not only are we providing solutions that address those today with current generation, we are engaged with them very closely on the next generation, on the upcoming platforms, whether they are GPU based or ASIC based to provide these solutions. Great example was the Aries SCM, where we enabled using our trusted solution for PCI Express Retimers. We enabled a new way of connecting some of these ASICs on the backend network.

And just maybe if I can add to that, one way to visualize connectivity market or subsystem is the nervous system within the human anatomy. Right? It's one of those things where you don't want to mess with it. Yes. There will be a sick vendor. There are options or off-the-shelf. Once the nervous system is built, tested, especially like what we have developed where the nervous system that we've built is specifically done for AI application. And there's a lot of qualification, a lot of software investment that hyperscalers have done. And they want to reuse that across different kinds of topologies, whether it's ASIC based or merchant silicon based. And we do see a trend happening, when we look at customers that we're engaged with today. And for protocols like PCI Express, Ethernet, and CXL, and especially where as Taurus plays, these are standards based. So to that standpoint, whatever end possible architecture is being used, we believe that we will stand to gain from that.

I guess as my follow-up one quick one for Mike, how should we think about OpEx beyond the second quarter? I know there's a bigger step up there with a full quarter of being a publicly traded company etcetera, but just walk us through your OpEx plans rest of the year or even to the target?

Yes, I mean, thanks Ross. We are continuing to try to invest quite a bit in headcount particularly in R&D. There's so many opportunities ahead of us that we love to get a jump on those products and also improve the time to market. That being said, we're pretty selective on who we bring into the company. So that will just meter our growth. And we believe our OpEx although it's going to be increasing will probably not increase at a rate of revenue over the near- and long-term. And that's why we feel good about a long-term operating margin model of 40%. So over time, we feel confident we can trend that direction even with increasing investment in OpEx.

Your next question will come from the line of Suji Desilva with ROTH MKM.

Hi Jitendra, Sanjay, Mike congrats on the first quarter here. On the backend, the addressable market here that's non NVLink, I'm trying to understand if the PCIe and Ethernet opportunities there will be adopted at a similar pace out of the gate or whether PCI would lead that adoption, in the non NVLink backend opportunity?

It's hard to say at this point just because there is so much of development going on here. I mean, you can imagine the non NVIDIA ecosystem, they will rely on standards technologies, whether it is PCI Express or Ethernet. And the advantage of PCI Express is that it's low latency. Right? Significantly low latency compared to Ethernet. So there are some benefits to that. And there are certain extensions that people consider to add on top of PCI Express, or when it comes to the proprietary implementation. So, overall, we do see this, from a technology standpoint, PCI Express will have that advantage. Now Ethernet also has been around, so we'll have to wait and see how all of this develops over the next, let's say, 6 to 18 months.

Yes. Add to what Sanjay said. I think the good news for us in some ways is that we don't have to pick, we don't have to decide which one. We have chips, we have hardware, and we have software. So we have customers that come to us and say, hey, I need this for my new AI platform. Can you help me with that? And then that's what we've been doing.

And then a question perhaps for Mike. The initial AEC programs ramping maybe a few customers this year, few customers next year or maybe perhaps all of them this year. But do you perceive that those will be larger lumpier program based ramps, Mike? Or will those be steady kind of build out to the servers grow?

I think the product ramps will mirror other product ramps well. They'll gradually build over a few quarters till they hit steady state. And if you layer them on top of each other it just continues to build a nice growing revenue profile. So as you look at Taurus in 2024, we're shipping 200 gig right now. And then in the back half we start to ship 400 gig. And if you look into 2025, 800 gig which is ultimately the biggest opportunity in a much broader set of customers, will be when the market really becomes very large.

Your next question will come from the line of Richard Shannon with Craig-Hallum.

Hi, guys. Thanks for taking my questions. Well, congratulations on coming public here. I guess I want to follow-up on a couple of topics here that have been hit on, including Suji's question here about the PCI Express, AEC opportunity. Are these design wins, or are these kind of pre-design win ramps you're talking about this year? And I guess ultimately my question on this topic here is, is can this opportunity, these PCI Express AECs become as big as your Taurus family in the foreseeable future?

Yes. So these are design wins to clarify. We have been shipping this. We announced this. We've demonstrated this at, at public forums. So to that standpoint, it's an opportunity that we're excited about and like we noted early on. We expect to start contributing revenue for later half of this year.

And the second question is on CXL. I think you've mentioned a couple of applications here. Maybe if you can kind of express the breadth of interest here across hyperscalers and other customers, for the ones you mentioned? And then also for the, next ones that are a little bit more expansive in nature, how do you see the testing and specking out of those? Are those coming to market at the time you're hoping for or is there a little bit more development required to get those to market?

Yes. There are two questions. Let me take the first one, which is the CXL side. For CXL, there are four main use cases to keep in mind, memory expansion, memory tiering, where you're trying to go for a TCO type of angle, memory pooling, and what is called as this memory drives that Samsung and others are providing. We believe memory drives are more suitable for the enterprise customers. And whereas the first three are more suitable for cloud scale deployment. And there, again, memory pulling is something that's further out in time is our belief just because it requires software changes. So the ones that are more sort of short-term, medium-term is memory expansion and memory tiering. And like I noted early on, all the major hyperscalers, at least in the U.S., are all engaged on the CXL technology. But it is going to be a matter of time with both CPUs being available and dollars being available from a general purpose compute standpoint. Okay. And then in terms of, your second question was, was that more on new products? Was that the context for it?

Yes.

Yes. So again, we don't talk about the exact time frame, but you can imagine our last product we announced was a little over a year ago. So our engineers have not been quite, so they've been working hard. So to that standpoint, we are working very diligently and hard based upon, lot of interest and engagement from customers that we've already been working with.

There are no further questions at this time. I'll turn the call back over to Leslie Green for closing remarks.

Thank you everyone for your participation and questions. We look forward to seeing many of you at various financial conferences this summer and updating you on our progress on our Q2 earnings conference call. Thank you.

Thank you, guys.

This concludes today's conference call. You may now disconnect.
