Thank you, Louis, and good afternoon. Thank you all for joining our call today. Our Q1 results were 1% above the midpoint of our guidance range, with revenue increasing 6% sequentially. As expected, both Auto and IoT revenue increased sequentially and the AI products were about 2/3 of our total revenue.
As previously discussed, our customers are in the midst of a recovering from a cyclical inventory correction and the favorable impact from this is expected to carry into the second quarter. We continue to expect our fiscal '25 revenue to grow year-over-year, driven by both the cyclical tailwinds and the secular growth in our AI portfolio. The combination of the cyclical and secular forces is expected to enable our AI inference revenue to grow more than 30% in fiscal 2025.
Zooming out for a minute the significant capacity being added to the AI training network infrastructure globally, both well for the ultimate deployment of AI inference at an age where we participate in the market. The deployment of AI inference at age enables end user to more practically take advantage of so many different AI breakthroughs. As a focus on AI at age of networks increased we see AI inferencing proliferating in multiple areas, and we believe we are well positioned to take advantage of this. In fact, we are already in the early stage of demonstrating how it may play out for us. In Q1, for example, our customer engagement includes our first passenger vehicle wins for our 5-nanometer CV3-AD family of AI central domain controllers. We added another CV3-AD win in the commercial vehicle market secured multiple enterprise class AI inferencing wins and even in other IoT cameras, we are reporting additional wins for our financial meeting C5 AI process. In the midst of this great change, our opportunity and the challenge is to develop AI technology and products that not only are extremely efficient for age deployment but also flexible enough to execute a very wide range of AI workload across all these disparate applications. We are already in mass production with our AI products for video-intensive CNA networks such as detection classification, fusion, planning, stitching, matting, tracking, framing, auto editing and the new network imaging signal processing.
Now our third generation of AI technology integrated into our CV3-AD and the CV7 series of SoC can support transformer networks for a variety of generative AI applications. I would now like to describe customer engagements that can offer some indication how it can play out for us. As you know, we have made significant investment into our CV3-AD family of automotive AI domain controllers, and we expect the CV3-AD family to be a major revenue driver. So we are pleased to announce our first CV3-AD family wins in the passenger vehicle market, which complements our ongoing wins with the CV3-AD 80 family in the commercial vehicle market.
In April, during the Beijing Auto Show, we reached a strategic collaboration agreement with a battery electrical vehicle company in China. This company will use our CV3-AD AI domain controllers in new passenger vehicle models. This is an important development for us in several regards. First, major by the number of EV deliver in calendar 2023, this OEM is considered 1 of the top 5 new EV companies in China. While most of the OEM delivers -- deliveries were in China last year, the company has an impressive plan for the globalization of its business. Second, Chinese automotive OEMs are aggressively and successfully adopting next-generation technology into their vehicles, which aligns with our strategy to intersect the safety and autonomy domain with next-generation technology, in particular, Level 2+. For example, to improve accuracy many OEMs in China have aggressively adopted the BEV former AI framework for 3D perception tasks in its autonomous driving software stack. And this high-performance framework can leverage to a high degree the unique capability in our CV3-AD AI inference processors, including the ability to process transformers at low power. Third, the efficiency and scalability of our CV3-AD family portfolio is also a major factor in the collaboration with Ambarella as the OEM can reuse the software on low, mid- and higher vehicles. In April, we added another CV3-AD family win in the commercial vehicle market with the announcement of a strategic collaboration with [indiscernible] Corporation. [indiscernible] is one of the world's largest engineering machinery manufacturers providing heavy-duty commercial vehicles to the global market. [indiscernible] intend to leverage Ambarella's CV3-AD family of automotive AI domain controllers to develop advanced automated driving solution on its next-generation commercial and special purpose vehicles. The company's will collaborate on the joint development and the promotion of high-performance and highly integrated automated driving solutions with [indiscernible] goal of achieving start of production for at least one model by calendar year 2025.
At the Beijing Auto Show in April, Tier 1 new -- Neusoft reach announced a strategic partnership with Ambarella. The company's plan to expand on their existing relationship to jointly promote and explore AI-based product technology and market development in areas, including autonomous driving and the driver monitoring. Neusoft's third-generation full-phase intelligent camera X-Cube 3.0 is powered by Ambarella's CV22 AI vision SoC to target Level 2 and Level 2+ autonomy levels and has already been much produced and deployed by automotive OEMs. We are pleased to announce that in machine, the leading provider of driver monitoring system software select our CV25 for its own aftermarket system for commercial vehicles. The Guardian Generation 3 meets the European Commission's general safety regulation for drowsiness detection, a requirement for all the new cars, vans, trucks and buses across Europe.
And in April, at the ISC West Security Exhibition, we successfully demonstrated the latest generating AI technology running region language model, VR on our N1 and CV72 SoCs. Our demonstration includes using the multi-model CRMs to search video recording to detect objects defined by tax and provide near instantaneous results without the need for training specifically for that object. This capability opens up a whole new range of AI-based search capability for enterprise cameras and primate based AI systems. Our third-generation AI influence technology includes specific support needed to efficiently run these new classes of networks.
During the ISC West, we also announced and demonstrated our new 5-nanometer CV75 AI SoC, which provides the performance required to run the latest VRMs as well as AI-based IQ enhancement. This capability to very efficiently run this cutting-edge AI technologies is highly sold after the -- sold after for cost and power constraint AI cameras used in enterprise smart city retail stores, robotic access control and AI-based consumer devices.
At the Enterprise Connect conference in March, Polly, a leading global provider of workplace collaboration solutions and wholly owned unit HP launched its Studio E360. This center of table system utilizes a single 5-nanometer CV5 for 4 mega pixel cameras with AI influences processing, choosing the optimal framing angle for [indiscernible] participants.
And also in Korea, the career activity for our AI SoCs remain high. With the leading security camera maker, Hahwa introduced new AI model base on our CV22 and CV2 AI SoCs and ideas introduced CV25 based models and Cpro introduced due sensor AI camera based on CV22.
In the other IoT market, we are pleased to see our 5-nanometer CV5 AI inference processor being utilized in another consumer cameras to significantly improve both image quality and to automate a certain user interface functions. Insta360 introduced its X4 action camera in April with steel sensor for 360-degree 8-K capture.
In conclusion, I mentioned last quarter, our goal are to restore revenue growth and the profitability will continue to drive our strategic R&D priorities. Q1 represented a step in the right direction, most scenically highlighted by our first passenger car -- passenger vehicle win for the CV3-AD family by the expanding breadth of CV customer engagement stands out. and we expect this to build a broad foundation on PON with multiple applications can drive revenue growth and result in positive earnings leverage for shareholders. The further commercialization and monetization of our technology and the product is of utmost importance to us, and I'm excited about the opportunity before us and what we will achieve in the years ahead.
With that, John will now discuss the Q1 results and outlook in more detail.
Thank you, Fermi. I'll now review the financial highlights for the first quarter of fiscal year 2025 ending April 30, 2024. I will also provide a financial outlook for our second quarter of fiscal year 2025 ending July 31, 2024. I'll be discussing non-GAAP results and ask that you refer to today's press release for a detailed reconciliation of GAAP to non-GAAP results.
For non-GAAP reporting, we have eliminated stock-based compensation expense along with acquisition-related costs adjusted for the impact of taxes. For fiscal Q1, revenue was $54.5 million, 1% above the midpoint of our prior guidance range, up 6% from the prior quarter and down 12% year-over-year. Non-GAAP gross margin for fiscal Q1 was 63.4%, above the high end of our prior guidance range by 0.4%. Non -- Non-GAAP operating expense was $46.7 million, approximately $2.6 million higher than the prior quarter and $800 million -- excuse me, $800,000 lower than the midpoint of our prior guidance range of $46 million to $49 million, driven by continued expense management and the timing of spending between quarters. We remain on track to our internal product development milestones. Q1 net interest and other income was $2.3 million. Q1 non-GAAP tax provision was approximately $607,000. We reported a non-GAAP net loss of $10.5 million or a $0.26 loss per diluted share.
Now I'll turn to our balance sheet and cash flow. Fiscal Q1 cash and marketable securities decreased $16.6 million from the prior -- million dollars -- from the prior quarter to $203.3 million. Receivables days of sales outstanding increased from 44 days in the prior quarter to 47 days, while days of inventory decreased from 131 days to 123 days. Inventory dollars declined 2% sequentially and declined 31% from a year ago. Operating cash outflow was $15 million for the quarter. capital expenditures for tangible and intangible assets were $1.1 million. We had 2 logistics and ODM companies representing 10% or more of our revenue in Q1. WT Microelectronics, a fulfillment partner in Taiwan, that ships to multiple customers in Asia, came in at 62% of revenue for the first quarter. Chicony and ODM who manufactures for multiple end customers was 13% of revenue for the quarter.
I'll now discuss the outlook for the second quarter of fiscal year 2025. We remain confident our business is continuing to recover from the cyclical correction, led by our AI inference products. For fiscal Q2, we estimate our total revenue will be in the range of $60 million to $64 million. We expect sequential growth in both IoT and Auto. We expect fiscal Q2 non-GAAP gross margin to be in the range of 62.5% to 64%. We expect non-GAAP OpEx in the second quarter to be in the range of $47.5 million to $49.5 million, with the increase compared to Q1, driven by increased head count and engineering-related expense, including our first 2-nanometer SoC project. We estimate net interest income to be approximately $1.8 million our non-GAAP tax expense to be approximately $600,000 and our diluted share count to be approximately 41.1 million shares.
Ambarella will be participating in Bank of America's Global Technology Conference on Wednesday, June 5 in San Francisco; Mizuho's Technology Conference on June 12 in New York City and Rosenblat Virtual Age of AI Conference on June 13. We hope to see you at one of these events. Please contact us for more details. Thank you for joining our call today.
And with that, I will turn the call over to the operator for questions.
[Operator Instructions] And our first question for today comes from the line of Christopher Rolland from Susquehanna.
Can you hear me?
Yes.
Yes.
You brought up VLM on the call. Just wanted to know a little bit more about that application. Does that increase your TAM overall? Is this additive to what you're doing in , for example, LLM? How should we think about that?
Right. So we start talking about LLM and start demoing at CES this year. And then we continue to watch the potential application that we can use with our solution for our customers. And we identify vision language model, which is really a large language model that can respond to tax for search different objects or using that to describe different video things, and we have a live demo in fact, we welcome to -- you to give to all lowest setup live demo for you, how the vision token model used in our -- with our current enterprise customers or other potential customers in that space. So this definitely is a brand-new application that being identified by the market and the customer, and we're engaging with our current customer, particularly on the enterprise and security camera market, and they showed extremely interested on this product because you can imagine that this is really a model that can replace the people who use to monitor the different cameras in a control center. And you can use a large language model, not to give you early morning, but also have using packs to do a search of different objects without really trending for those objects. And I think that's really a breakthrough for enterprise side, and we expect that some of our customers will kick off projects with us with VRMs in the near future. And we can use both N1 as well as CV72 for that product.
Great. And then, on the Auto opportunity, making some progress here sounds like on the Chinese EV side of things. Perhaps you can talk about the pipeline, kind of how you see expanding engagements of late here that you're seeing and whether you think there's going to be more to come and whether any of these could actually be implementing your software as well?
Right. So first of all, I definitely believe there will be more to come. And I also believe that the first design win is really sure that our -- we have been talking about our strengths, which is we can run really transform our most advanced network very efficiently in low flow power and also we have a scalable architecture that can really address using a sense over to address from low end to the high-end vehicles and also that the power consumption that we're much lower than our competitors give significant bond advantages in the design win. So that really is the reason we won. But also, I think it's important to point out that just like the EV market, Chinese EV automakers are really aggressive by pushing technology envelope and for one of them adopting our Level 2 product solution is will help us for other potential OEM design wins that we're building on. .
And our next question comes from the line of Ethan Potasnick from TD Cowen.
This is Ethan Potasnick on for Matt Ramsay. Congrats on the great results. I wanted to ask, is the passenger vehicle win you guys discussed tonight, likely to get CV3 to the tipping point with regards to wins at other OEMs? Are there -- and are there other OEMs waiting to see maybe another one kind of go first? Maybe if you guys could discuss those dynamics.
Right. So first of all, I think the lifetime value of this design win is meaningful and also material for us. And also that we are very aggressive to target MP date at the end of '25, early '26. And that will help us to really take our CV3-AD platform into production and therefore, provide a mature solution to other companies who is considering our current solution. So I definitely believe that not only this design win is help to our pipeline, but also going to be a major help for us to secure other design wins in the near future.
Okay. Understood. And as my follow-up, you guys gave a lot of good information around the AI inference opportunity with revenue expected to kind of grow 30%. I think you guys said in fiscal '25 and you called out some progress, I think it was enterprise applications. I was wondering how these -- how the early stages of this opportunity is playing out? What sort of impact some of the announcements you guys made at CES, I think it was the N1 SoC and the Cooper development platform or -- what's kind of driving that? How is the road map progressing? Any early feedback? And any additional insight would be helpful.
Right. So just maybe refresh our AI strategy. We definitely intend to leverage our current existing third-generation AI inference engine into an AI and LLM. And we deal like you said, CES, N1 with Lava demo and then at the ICS will demo with VLM, running on both N1 and CV7. So our strategy for current generation has become very clear. First of all, we're going to focus on each application, both for H camera as well as H servers. Two, we'll focus on the workload that we can -- really can take advantage of our current silicon. And so that's really enterprise market as well as some adjacent markets that can use those Lava model as well as VLM models. And we think -- we continue to believe that our opportunity for AI revenues in 2026. We are not only demoing, we're sampling N1 and the CV72 to our key customers who are interested in can application. So that's our first generation.
And also, as you can see, I think John mentioned that we are investing on 2-nanometer process node, you can think that's a preparation for our next-generation Gen AI solution, although we didn't talk about our plan for that yet. We are trying to work on that. But we believe that with our 2-nanometer technology development will significantly help us on the technology side for our road map.
And our next question comes from the line of Joe Moore from Morgan Stanley.
In terms of the passenger car win in China, can you talk about -- I think you mentioned it as an L2+ if I heard you right, type of opportunity. Can you kind of describe how many cameras per car and what capabilities you could offer there?
Yes. So first of all, it is an L2+ car, and because they have different models, it's anywhere from 7 to 10 -- 7 to 10 cameras plus radar configuration. And it's designed to do it from the highway level to CD levels of automodriving.
Great. And then was this customer -- I know you have a probability weighted funnel -- was this customer somebody that you had anticipated had some probability within that funnel?
Yes. And now I think with the next final discussion, they should be in one category in set probability of the category.
And our next question comes from the line of Kevin Cassidy from Rosenblatt Securities.
And congratulations on the great results and the design win momentum. And maybe, Fermi, maybe you hinted, I was going to ask more questions about the 2-nanometer process technology. Do you have a time line for when you'd have first silicon and are you staying with Samsung? Or will this be with TSMC?
Right. So this 2-nanometer will be sent 2-nanometer, and we plan to tape out second half of next year and get ready to go into production with 2026.
Okay. Great. . And maybe just a follow-up on Joe's question. You mentioned that it's 7 to 10 cameras plus radar. Is that your radar in the design?
We haven't talked about that yet.
Okay. All right. Maybe I'll go to an easier question with just -- your backlog visibility, if you're saying you're going to see growth in fiscal year 2025. It -- can you talk about your backlog visibility?
Yes. Our backlog visibility getting much better than before. In fact, that's the reason we feel comfortable that with the Street consensus of $250 million revenue forecast this year. And we -- our lead times are really in the 24 weeks and that tells us that we should have a clear visibility to middle of Q4, reminding you that our Q4 is to January. So we see clear booking for Q3 and Q4. That's why we continue to feel comfortable with our guidance. However, let me add one more sentence. I think that we are comfortable with the $250 million consensus level we believe there is a seasonality in Q4. So I think that is something we should consider. While the -- while we see the visibility we definitely believe that we're going to continue to see the trend of Q2 to Q3 growth. But from Q3, Q4, just like the normal seasonality before the core, we should have seasonality in there.
And our next question comes from the line of Quinn Bolton from Needham & Company.
This is Nick Duval on for Quinn. Maybe just zooming out a little bit, could you give us a pulse on the Chinese auto market overall? How do you see current EV demand and supply? And then you mentioned wins in the passenger and commercial markets, can you size those opportunities at all?
Right. So first of all, we don't play on the EV market, we play on the autonomous driving market, but they are very much correlated. I think what happened in EV is that Chinese automakers continue to aggressively push the technology envelope on the EV side. We see the same trend on the auto driving technology side. I think, for example, that almost all the RFQ that we're building in China, all of them require most advanced network like BEV former very L2+ C-level autonomous, all of that is really showing me that they are very Chinese automakers are very aggressive to push the technology envelope. And we believe that's played to our strength, and we believe that we can take advantage of that. Although that market show some slowness in terms of total market size. But I think that from an AD market point of view, we still believe that the growth has continued to be there, and we expect that majority of the EV cars will have a Level 2, Level 2+ system in the coming years, near term.
Okay. The margins -- the gross margins were a bit of a bright spot in the quarter and guide. Could you expand on what's driving that?
Yes. So essentially, it's mix. We had little bit higher contribution than we had forecast for customer NRE projects that came through in the quarter. That's the main driver.
And our next question comes from the line of Tore Svanberg from Stifel.
This is Jeremy calling for Tore. And let me add my congrats on the growing CV3 design win. Maybe a quick follow-up on the gross margin and NREs. Is the NRE something that is kind of like an ongoing project or sustainable in terms of contribution over the longer term? Just want to see the impact, I guess, to gross margins over the next 12 to 18 months. That's my first question.
Okay. So yes, we did -- it is a project that will be ongoing in the near future. Our long-term model, though, is [ 59 ] to [ 62 ] for gross margins. I think there may be a temporary -- temporary blip up for this quarter, next quarter potentially as we've guided. But I think if you're thinking about long-term modeling, I wouldn't see this as a new norm necessarily.
Got it. And I guess in terms of this passenger vehicle design win, can you give us a little bit more detail in terms of like how many car models are impacted if there's a way to kind of weight it in terms of how many of the new vehicles are likely to see this incorporated. And also, I understand the ASPs even in L2+ can have a pretty wide range, maybe $40 at the low end, $200 at the higher end. Can you give us a ballpark where this fits in terms of the design win and the ASP side?
Right. So first of all, this currently, this OEM has only a portion of the model has Level 2+ in there. But I do believe, just like any other Chinese OEM, we talk to -- they want to move to Level 2+ to all their models because they view that as a huge differentiation. So I think we expect when we go into production with this customer all of the car, they ship it will have a level -- some kind of Level 2+ solution there. As we talked about in the past, in our low-end to high-end chip, it can go anywhere from $50 to $400 and the midpoint is $100-plus to $200. That's the range we're looking at from an ASP point of view, and we will start addressing more -- we have -- we can disclose more with our customer.
In terms of the size of this true opportunity, I really think that it's we -- we talked about the significant -- I think it's north of $100 million easily for the first design win, but we think that we can achieve more if we can continue to work with our customers, getting more models and more other components into the car.
Sorry, I didn't quite catch how much -- how many million was for the first design win.
I say north of $100 million.
Low to $100 million.
North.
And our next question comes from the line of David O'Connor from BNP Paribas.
Maybe just going back to the seasonality in Q4, just looking back, there recover that you talked about seem to be down like 15%, 20% Q-on-Q. Is that kind of the type of ballpark or the code we should be thinking of for that Q4 seasonality? Or is it a bit more muted than that given the secular trends that you're seeing? That's my first question.
Yes. So I think it's relatively difficult for us to give, Chris, visibility out into Q4. But I think if you're thinking about the full year guidance of -- or I should say, the consensus of $250 million, I think that's definitely reasonable at this point. We don't have any issue with that. I think, though, the number -- the percentages you're talking about are within reason.
We have seen this kind of a seasonality before cavity. And I think right now after the COVID -- after the inventory correction is done, I think we're back to the normal seasonality. And with clinical -- with the downturn, we haven't provided guidance in Q4. But I think if you look at the past history, that will be probably -- if you look at the pattern, it will be similar to the seasonality we've seen before. Majority of that is in the IoT side, but a little bit on the auto side.
Okay. Got it. That's helpful. And then maybe just a follow-on on the CV3 win with the EV passenger vehicle. Just to clarify, I mean, this is separate to the Conti Bosch agreement. Did it have anything to do with that? And can you update us as well just on the status of those agreements where they stand at the moment?
First of all, this design has nothing to do with the Conti or Bosch. This Chinese guy is really using a Chinese supply chain. And in terms of accounting, I will say that we continue to have very strong collaboration both on the SoC and the software side. And also, we continue to make progress moving towards our first SOP project that we talked about probably a year ago, and that target MP time is kind of year '27. We continue to make great progress on that. And also, we're actively bidding on the RFQs with Conti on this. So with the Bosch side, also, we don't have a software development of collaboration, but we do have working with them on the RFQs bidding on some of the European design wins.
And our next question comes from the line of Richard Shannon from Craig-Hallum Capital.
Maybe touching on your comments about AI inference growing 30% or more this year. Maybe give us a sense here of how much this is weighted towards IoT versus automotive? And then any kind of general sense here of how much unit versus ASP driven. And then it seems like you do the basic math using the fiscal '25, it seems like AI would probably get a little over 70% of sales this year. Is that a decent math on that?
I think your math is correct. Let me give you more color. I think, first of all, our -- we have a lot of design wins on the CV5 -- CV72, and particularly CV5 we talked about that production -- getting into production this year, and we talk about that we're going to ship 1 million units of CV5 this year and consider ASP is around $35 plus minus, and that really helped us to get an ASP jump as well as revenue growth. So one side of CV growth.
The other side CV growth is that we believe CV72 well getting to production with enterprise IoT, and that's another one. And -- but also -- but however, I also want to point out that even in automotive, we continue to ship. For example, we just announced a design win with a Neusoft on the A-R with CV22 and -- as well as a few other design wins we had with automotive. So I think both IoT and Auto well continue to have a semi growth in there, but I think IoT is probably more.
Okay. Perfect. That's helpful, Fermi. A follow-up question here on a different topic and then of kind of China U.S. geopolitics here, obviously, in the context of couple of nice wins here with the CV3-AD demand controller going into China. Just wondering if there's any change in the kind of the undercurrent of geopolitics that might make it a little bit more of a headwind to continue to do well there. Just want to get a general sense or if there's been any real change there.
No, I don't think there's any meaningful change in the last 3 months. I think the geopolitical situation continues to be an issue that we need to watch and to deal with. I think that we talk about that Chinese market -- Chinese customer we really want to make sure they use some local components. But however, I think with the advantage we have especially for customers who are focusing on the export business, they also need to use a silicon from outside China. So I think that's kind of a balanced view we have right now and that hasn't changed. We haven't seen any new regulation from any regulation to change this AI limitations.
[Operator Instructions] Our next question comes from the line of Kevin Garrington from WestPark Capital. .
Yes, let me echo my congrats on the strong results. Fermi, on the automotive side, I know you noted that you're more focused on autonomous driving and the market is pushing more towards EVs. But are you seeing combustion engine opportunities? And are any kind of automotive OEMs backtracking from originally thinking about developing EVs to maybe giving you opportunities in combustion engine or hybrid vehicles as well?
Absolutely. I don't think AD is exclusively for EV at all. I think we continue to see RFQs for -- for commercial engine -- cars and also hybrid cars. So I won't say that's exclusive, but just like first design wins, it just happened to be a pure EV company. And that also shows you that all the EV companies trying to find possible differentiation other than just the battery life, but also adding AD capabilities is one way that can differentiate. So I think that this AD application go to all kind of cars, including both EV as well as combustion engines.
Okay. Perfect. That makes a lot of sense. And then going off of Richard's previous question, you noted in your prepared remarks, AI inferences proliferating in multiple areas and your AI revenue would grow at 30% this year. You have a bunch of design wins in the pipeline is the AI inference market kind of taking off as quickly or not as quickly as you originally were kind of thinking? And is it developing into as large of an opportunity as you had imagined?
Well, for the IoT side, I think we do think that enterprise IoT is growing as fast as we expected. We get some surprise on the other IoT space. But I think that one thing that didn't grow as much as we expect is automotive. We have been investing heavily on CV3-AD market and we got the first design win. I think there's a lot of things for us to work on to make sure that we can continue to take advantage of our investment in AI inference engine in automotive markets.
And our next question is a follow-up from the line of Tore Svanberg from Stifel.
This is Jeremy again. Just a housekeeping question. Did you provide the split between auto and IoT. And if you could just refresh us on what those splits were for the last couple of quarters?
You're talking about revenue split between Auto and IoT. Is that a question?
Yes, that's right.
Yes. So if you look at last year, I think IoT was roughly 2/3 of total revenue and Auto is 1/3. And if you look at inside IoT, enterprise securities to continue to be the largest portion and last year consumer IoT and other IoT are roughly the same size. But if you look at the growth this year, I think that inside IoT, enterprise and other side IoT is growing faster. And also, we expect growth this year.
This does conclude the question-and-answer session of today's program. I'd like to hand the program back to Dr. Fermi Wang for any further remarks.
Thank you, everybody, for joining us today, and I'm looking forward to see you talk to you in our conference call next time. Thank you.
Thank you.
Thank you, ladies and gentlemen, for your participation in today's conference. This does conclude the program. You may now disconnect. Good day.
