Thank you, Annie. Good morning, everyone, and welcome to Silicon Motion’s second quarter 2021 financial results conference call and webcast. As Annie mentioned, my name is Chris Chaney, I’m the Director of Investor Relations. Joining me today on this call are Wallace Kou, our President and CEO; and Riyadh Lai, our CFO. Following my comments, Wallace will provide a review of our key business developments, and then Riyadh will discuss our second quarter results and our outlook. And then we’ll conclude with a question-and-answer period. Before we get started, I would like to remind you of our safe harbor policy, which Annie just read at the start of the call. For a comprehensive overview of the risks involved in investing in our securities, please refer to our filings with the U.S. SEC. For more details on our financial results, please refer to our press release, which was filed on Form 6-K after the close of the market yesterday. This webcast will be available for replay in the Investor Relations section of our website for a limited time. To enhance investors’ understanding of our ongoing economic performance, we will discuss non-GAAP information during this call. We use non-GAAP financial measures internally to evaluate and manage our operations. We have therefore chosen to provide this information to enable you to perform comparisons of our operating results in a matter similar to how we analyze our own operating results. The reconciliation of GAAP to non-GAAP financial data can be found in our earnings release issued yesterday. We ask that you review it in conjunction with this call.

Thank you, Chris. Hello, everyone, and thank you for joining us today. In the second quarter, we delivered another quarter of record sales and earnings. Revenue grew 21% sequentially to a record $221 million and earnings per ADS for a record $1.50. Sales of SSD controllers and eMMC+UFS controllers grew in the second quarter and both achieved record quarterly sales. We delivered better-than-expected growth and profitability, primarily by up selling a richer mix of products, allocating more product to higher-margin accounts and where possible, repricing product to cover higher manufacturing costs. Additionally, our operation team has been actively working with our contract manufacturers to tune back end processes to improve manufacturing yield and lower costs. This 4 pronged initiative of upselling of richer mix of products, optimizing product allocation, better pricing discipline and tuning manufacturing processes is critical for creating continued value-add growth and profitability when our manufacturing capacity this year is capped and manufacturing costs remain elevated. Based on the fusion of the initiative, we are now also expecting better gross margin for the rest of this year. Earlier this year, we had communicated our 2023 $1 billion sales objective and growth road map. We will likely achieve this target much earlier. Based on our latest sales projection, our annual run rate is expected to be already at least $1 billion by this year’s fourth quarter. We expect sales of ultimately exceed $1 billion next year as we add meaningful incremental foundry capacity already committed to us and from continued execution of our 4 prong initiative, which includes upselling a richer mix of products. Sales next year will include the rapid scaling of a higher value, high-volume PCIe Gen4 SSD controller. Our customers have also provided us with purchase orders for the next year, and the order book today already exceeds $1.5 billion. Our strong order book is a result of many years of hard work. No last minute opportunistic procurement audit of all the shelf parts by customers. We have been building our business pipeline for many years, leading to these purchase orders. Our OEM projects typically kick off 1 to 3 years before initial sales, depending on product capacity. Projects start with defining the OEM product features and customization requirement before hardware and firmware product development and end with product comparability, performance verification, analysis, quality assurance and manufacturing support activity before we start to manufacture and sales of our controllers. What is clear from our design wins and order book, we have been gaining share of wallet in some of our NAND flash and Tier 1 module maker customers. Several of our customers have been gaining market share in the SSD and UFS marketplace. SSD and UFS adoption continue to grow in PC and smartphones, and our customers are actively using our controller to develop storage solutions for new applications that include game consoles and automotive systems. Our order book runs through full year 2022, and our pipeline of design wins include delivery beyond 2022.

Thank you, Wallace, and good morning, everyone. I will discuss additional details of our second quarter results and then provide our guidance. My comments today will focus primarily on our non-GAAP results unless otherwise specifically noted. A reconciliation of our GAAP to non-GAAP data is included with the earnings release issued yesterday. In the second quarter, revenue reached a record $221 million, 21% higher sequentially and 62% higher year-over-year. Earnings per ADS were $1.50, 35% higher sequentially and 84% higher year-over-year. Now I will walk through the performance of our 3 key products during the first quarter. SSD controller sales increased 30% to 35% sequentially and 105% to 110% year-over-year. Growth was driven entirely by our PCIe Gen 3 SSD controllers, which are primarily for OEMs eMMC+UFS controller sales also reached a record high, growing 10% to 15% sequentially and 25% to 30% year-over-year. Growth was driven by our UFS controllers. SSD solutions sales increased 35% to 40% sequentially and were down 15% to 20% year-over-year. Our Ferri products grew year-over-year, while our Shannon products declined sharply. Gross margin in the second quarter increased slightly to 51% from 50.7% in the prior quarter. As Wallace had discussed earlier, our better gross margin compared to guidance came from the execution of our 4 pronged initiatives of upselling, a richer mix of products, optimizing product allocation, better pricing discipline and the tuning of manufacturing processes. Operating expenses in the second quarter were $48.4 million, $4.5 million higher than the prior quarter, primarily from higher compensation accruals. Operating margin in the second quarter was 29.2%, an increase from 26.6% in the first quarter and up significantly from 22.2% a year ago. Our 29.2% operating margin this quarter is higher than the 26% to 28% guidance due to stronger revenue growth and better gross margin, partially offset by higher operating expenses. We are delivering strong operating leverage and making good progress towards our 30% operating margin targets. Our effective tax rate in the second quarter was 18.6%, slightly lower than our 20% tax rate guidance. Stock-based compensation in our operating expense, which we exclude from our non-GAAP results, was $2.4 million in the second quarter, within our guidance of $2 million to $3 million. We had $412.3 million of cash, cash equivalents, restricted cash and short-term investments at the end of the second quarter compared to $371 million at the end of the first quarter. We paid $12.2 million in dividend to shareholders. The third quarterly installment of our $1.40 per ADS annual dividend that was announced last October.

First question comes from the line of Ariel of Needham and Company.

Yes. Thank you and congratulations on the great momentum that you’re seeing. When you’re indicating that your order book now points to $1.5 billion. I’m wondering if you could elaborate further on what you’re seeing within that order book. What’s driving the uptick in the growth? And then secondly, can you talk about your conversations with TSMC regarding capacity allocation next year, what have those conversations been like? How much capacity has been allocated to support those targets? Thank you.

I think regarding from our order book, $1.5 billion majority come from OEM projects and some come from the order, the backlog, we cannot ship this year. So we have a solid $1.5 billion. By end of this year, we believe we should see even much higher in our backlog. Regarding the discussion with the TSMC, as you -- everybody know, TSMC probably has announced they see the wafer allocation will continue through the 2021 also to entire 2022 because all the new investment probably will not contribute mature technology until 2023. With the incremental company wafer supply, we have confidence to increase our sales revenue to grow in 2022 with fair amount of percentage. However, we will continue to negotiate discovery TSMC and other foundry maker to increase wafer supply in order to meet the very large amount of demand from our worldwide customers.

With respect to the upside in gross margins that you’re seeing in the quarter. I’m wondering how sustainable that gross margin shift is, you mentioned in the press release a shift towards higher-value products, higher -- you’re now engaging in where you can actually increase the price. I think that’s a change what you talked about before, where I believe the pricing was set in some of these contracts. So maybe you could talk a little bit about those 2 dynamics in terms of pricing and also in terms of mix of higher, richer mix of products?

We feel very good about our current situation. With the rollout of the initiatives that Wallace had pointed out earlier, focusing on up selling a richer mix of products, allocating more products to higher-margin accounts and where possible, repricing products to cover our higher manufacturing costs. These are all initiatives that we’re already executing, and we’ll continue to execute throughout the rest of the year and into next year. So we feel very good about our gross margins at today’s levels, extending through this year and into next year. And possibly, if there are opportunities, we’d love to take up our gross margin even more than where we are indicating, but there’s a lot of work to do. And for what we’re doing right now, the gross margin guidance that we just talked about, those are numbers that we feel fairly comfortable about.

Next question is from the line of Anthony Stoss of Craig-Hallum.

Riyadh, probably for you. Can you give us a breakdown of your non kind of notebook business? What percent of revenues that might be, the IoT bucket, if you will, what kind of growth rates you’re seeing? And then I had a follow-up after that.

So for the notebooks products primarily related to eMMC+UFS as our SSD controllers are very PC, noble PC oriented. Now for the eMMC+UFS, they were about 25% to 30% of sales last year, and we expect this to inch up this year given the very strong growth. And within that bucket, a large part of it is smartphone, but we also have a lot of eMMC going into non smart applications. Was a -- I mentioned a long list of those applications are very popular with consumers, including smart TVs and other application, smart speakers. So these are products that are still growing, and we expect this part of the market to continue to grow modestly over the foreseeable future.

Okay. And then just as a follow-up, the question that I get asked most from investors and increasing amounts recently is a share buyback. You have incredible visibility. You’re talking about an order book of over $1.5 billion heading into next year, 3 years worth of visibility, you got a stock trading at an 8 -- cash. It just astounds me and investors that you guys haven’t initiated a share buybacks. So I’m hoping your Board has listened to this call, and I’d love to hear your thoughts on why you haven’t initiated a share buyback.

Tony, our primary means of returning capital to shareholders is from our dividend payments. And historically, we paid up to half of our free cash flow. Given our very strong operating performance and good visibility into 2022, it is likely that our Board during the next dividend declaration in October, they could consider something a dividend higher than what we paid last year.

Next question is from the line of Craig Ellis of B. Riley Securities.

Congratulations on the very strong performance in the business. I wanted to start with a question for Wallace. And Wallace, what I want to do is kind of pick up where I left off on the last quarter’s call where I inquired about really the trends you were seeing as more of your customers look to outsource eMMC controllers and you lined up with a dominant sure of the market like you talked about again today. And the question is a little bit different, and it focuses on the SSD controller opportunities. Given the very robust outlook you have for PCIe Gen4, do you get the sense that more of the NAND OEMs are starting to outsource more of their controller works? And to the extent that they are, to what extent do you think you’re going to benefit or benefit disproportionately from such a move?

It’s a very good question. In general, we see NAND maker, they all want to maximize their NAND day solution profitability. For eMMC, it’s very natural because eMMC, the every day is small. Maximum is 64 gigabyte. It’s very few in 120 gigabyte. We see a lot of the even 32 gigabyte application. So NAND maker, they also see the wafer supply constrained. So they move out the wafer, variable wafer move to higher density solid product. That’s why we see tremendous demand from eMMC controller to our company, a direct meter from NAND maker, our leading module maker, we have much more than we can supply and support. But we will continue the effort and try to not industrial breakdown for eMMC solution to many, many consumer electronic devices. For SSD, that’s another story, because we do see NAND makers, they have a tendency to start to outsource mainstream and value line project to third-party like silicon motion. Because we have a strong track record with long history with all NAND makers that we become the default standard candidate to take the opportunity. Frankly speaking, today, we have a more project opportunity than we can -- we are resorting support. So this is very, very important moment. We’ll continue to grow and recruit talent and R&D to join us and continue work on or really new project to make it successful. It’s very, very important is because the new generation of technology for NAND beyond one layer or even beyond 200 layer is very critical for controller maker have deep knowledge work closely with the NAND maker, so we can provide sufficient compensation for NAND endurance and retention. This is very, very important. We can work closely with NAND maker deliver various profound solution to the OEM customer as well as consumer. So this is a great opportunity, we see the trend will continue, and we are in a very favorable position to take the opportunity on all source opportunity from NAND makers.

And then for my follow-up question, I wanted to flip it over to Riyadh. Very helpful framework that you’ve provided and that Wallace’s provided on the factors that are leading to higher gross margin. And Riyadh, my question is for the change in gross margin in the back half of the year that we’re seeing very significant improvement from prior expectations. What’s the relative contribution from each of the 4 factors that were mentioned? And as we look to calendar ‘22, which of those factors has the greatest potential? And how significant would that be for further gross margin improvement?

Craig, the largest piece relates to our product mix, which also includes our allocation of products towards higher accounts. The initiatives relating to these moves have been the biggest driver in terms of contributing to higher gross margin. But that said, where possible, we also seek to reprice our products to better reflect the higher cost of our products that we’re seeing going into what we need to do to deliver.

Our next question is from the line of Karl Ackerman of Cowen & Company.

This is Eddie for Karl Ackerman. I have a couple of questions. There have been reports that your largest foundry partner will increase 28-nanometer capacity from 40,000 to 100,000 wafers per month by the end of this year. While that should enable you to fulfill existing customer orders, have you seen any indication from NAND OEMs resourcing earlier decisions to outsource to next year as incremental capacity on the line?

I cannot comment for TSMC because they have their re capacity guidance and because some factory expansion also relate to some political issue, and we really have no insight, sorry. However, we do know the -- we do have many opportunities come from NAND maker out directly from major OEM customers, including the very large sale customer from automotive as well as other sectors. Now it’s really how we really can manage so many opportunities under the supply shortage condition, it has to be very careful to make a decision because when we commit, we have put all the resource development, IP, support development, quality people, everything and count. And we have to make sure to use our R&D resources wisely in order to get a sufficient financial return. It’s very, very important. We don’t really worry about the business today. We just -- our constraint is the wafer supply. So that’s the most important thing we should focus on and to secure more supply in order to meet customers’ demand for next year and 2023.

Eddie, let me also add with the investments at TSMC have been announcing, we do not believe it’s going to change the direction of our NAND partners outsourcing to us. The reason Wallace has talked about earlier.

And another question is NAND demand appears to further outset supply and our field work indicates NAND OEMs are prioritizing high capacity SSDS. And in the past, as NAND capacity has silent, OEMS, enterprise SAs and then became a growth challenge for you. May you address why that reasoning may not make sense in the current environment. And thank you, and congrats on the results.

This year, it’s the underlying condition that we’re facing for our business is more about the supply picture. We have demand that is significantly outstripping our ability to deliver. So the underlying conditions on the NAND flash dynamics side of industry conditions, whether their allocation is more towards enterprise or into other applications. Those decisions have no real material impact to our business as it relates to the shifting of the demand picture. Right now, the key focus for us is about the supply side, how we can drive more products given the supply capacity that we have on hand.

Next question is from the line of Suji Desilva of Roth Capital.

Congratulations on the momentum here. So given the NAND supply demand situation, I’m wondering if the mix of OEM versus module maker is higher historically if you’re leaning your shipments toward OEM. And if that’s one of the factors in the gross margin tailwind that might correct back if module makers get allocation get the future.

I think it’s a very good question. I think every company has to make the wise choice but keep a balance. Our definite OEM project is more important because we have to allocate sufficient wafer and to supply the OEM project because that’s what we commit. At the same time, we also want to balance market maker. We don’t want the majority margin make die because many of them being with us for 16 or 18 years. I think we really have a look at the product itself and important for the supply chain. If the customer -- the insisting customer, they have multiple stores, sometimes we will try to reduce the weight. But really, we are sole supplier, we have to make sure we can net to fulfill the supply. It’s a pretty complicated decision equation. But through that, we also will review all of the gross margin from -- among all the products and put as a priority. So this is the thing we feel very comfortable because it doesn’t matter every customer, I think they all based small percentage, a large percentage shortly from Silicon Motion. We feel very sorry for that situation. That’s why we work very hard to try to secure more wafer to meet the customer demand.

Suji, let me also add, some of our module makers are now very large and very sophisticated and our ability to -- and are already engaged in taking projects with OEMs like the PC OEMS. And so for these large sophisticated module makers, we don’t treat them any differently than the NAND flash makers. And the level of profitability, it really depends on the projects. It doesn’t necessarily mean that the profitability is better with one class of customers or the other. It really is the value asset that we are bringing that matters.

And then the SBC Solutions business, trying to understand where the Shannon revenue level is now, is that going to have a further step down as you kind of manage away from that? And what the margin implications there? I imagine that’s also a lower-margin business that you’d be moving away from?

Regarding Shannon business, our really main goal this year and net transition has really maintained the relationship with the customer because it’s also Shannon some NAND procurement also is challenging. We do not want to grow Shannon business due to lower margin to dilute overall gross margin. But however, we have maintained certain important part in gate with Alibaba by do a major customer, make sure that our development technology will continue waiting for our really Gen5 major controller coming and to shine the market. But I think it’s also due to -- because we have a wafer constrained with allocation. That’s why we have to allocate carefully that we have so many OEM demand from NAND maker as well PC OEM and smartphone customers.

Next question is from the line of Mehdi Hosseini of SIG.

A couple of follow-ups. And thanks for -- and also, thanks for providing visibility into ‘22 with minimum revenue of $1.5 billion. And the question I have here is, what are the key growth assumptions for different sectors? And if you don’t want to elaborate, how should I think about the fastest growth versus the relatively lower growth segment?

I will say, our client revenue will continue to grow. Although PCIe Gen3 next year growth rate will be modestly, but PCIe Gen will grow very strong to carry because we have a very large design share in PC OEM. We stated almost 50% higher by end of the next year so that we have 8 different customer, 5 on NAND maker with our PCIe Gen4 controller and ramping next year. For eMMC+UFS, we also will grow very, very strongly. It also depends how many wafer we can secure. We say it’s going not to grow for a certain level, we guarantee is exceed the $1 billion of revenue next year. But we think the backlog will continue to pile up by end of this year. But we’ll continue to work very hard to secure more wafer, especially in mature technology because many eMMC are in 55, 40-nanometer and 28 meter, these mature technology wafer are in severe allocation from all foundry makers. So this is very critical, how fast we can porting, work with TSMC as well as other foundry that can grow overall the eMMC+UFS business.

Wallace, PCIe 4.0 is used for commercial segment of the notebook. Is that correct?

It’s used both commercial and consumer. We have 2 generations of mentioned PCIe Gen4 controller. One use 28-nanometer, one use 12 nanometer. This year, we’re ramping with more 28-nanometer next year, majority will be transition to 12 nanometer.

I think what I was trying to highlight is there is a concern that a consumer notebook like Chromebook may roll over. It can’t grow 20-some percent plus per year in the perpetuity. But I think commercial segment, which has been relatively quiet or muted, could turn on, and that’s a significant positive catalyst for silicon motion. Am I thinking about this the right way?

Let me just try to get it straight. Chromebook this year, the total volume is around 40 million to 50 million units is very small. And majority use eMMC, not SSD, they’re using embedded SSD. And we are in a very small portion in the Chromebook today and the Chromebook going up and going down, have relatively no impact to our business. And for SSD, we talk about really for mainstream notebook. And for both commercial for corporate accounts of consumer notebook. So that is to use M0.2 SSD. And that portion, I think, will grow very strongly and consistently without the top 5 PC OEMs sure.

And then one follow-up for Riyadh. Is it a product mix that is going to put a lid on the gross margin in the back half of the year despite sequential revenue growth, it seems like margins are going to calm down. And I’m just trying to better understand, is that because of a higher base? Is that because of the mix? Or is it just your year-end gross margin operating margin guide is conservative?

Mehdi, our gross margin expectations for the second half of the year is going to be significantly higher than what we had originally guided. But obviously, we still have a lot of work to do. We love to take our gross margin even higher than what we’ve just talked about. And so this is going to be coming from the continued execution of the initiatives that the 4 prong initiatives that Wallace had talked about relating to upselling our product mix to richer product mix, relating to how we allocate towards higher-margin accounts, more profitable accounts relating to the ability to reprice our products where possible to reflect the higher costs that we have in our products. And furthermore, we’re also working -- our operations team are also working very hard to see how we can better debottleneck our processes with our contract manufacturer back end services. So all 4 of these are still in execution. And the more we are able to work our initiatives, the better our gross margin could be. But as a baseline, the gross margins we talked about are what we’re guiding. And if we can execute even better, we’d love to take up our gross margin higher than what we decided.

And on the execution side, you’re executing flawlessly on managing working capital. Your free cash flow margin for the June quarter was 25%. You have grown cash. And if I just take your base assumption for ‘22 of $1.5 billion of revenue, your cash could go towards mid-teens, $15 net cash per share. And I know the question came up earlier, but I’m going to ask it again. Is there something you can offer us, why not become more aggressive with buyback? Or why not consider a strategic options because the cash is going up, valuation not changing, and I’m just trying to think how the management team is thinking about reconciling execution, free cash flow margin with the valuation on share price.

So I think, let me just answer the question. I think you’re looking for Silicon Motion today, our outstanding share total diluted 35 million shares. So really, it’s not really very meaningful for us to do share buyback. We -- as Riyadh said, we -- and the Board when we have more free cash. We either do more investment for certain MMA or we would have potentially increase the dividend. That is a Board to try to provide to the shareholder. I think this is the direction we think in next quarter is likely to happen, but wait for the next quarter after forming.

And Mehdi, let me add, historically, we’ve been pretty good about returning capital to shareholders. We typically return up to half of our free cash flow, and we’ve been doing that, returning half of our free cash flow to shareholders for over the last few years, and we expect to continue that. And for us, the primary means of returning capital to shareholders is through our dividend payments. And so with our upcoming -- we’ve just paid our third installment of our quarterly dividend. The last one will be coming soon. So by the October of this year, we’ll have to decide on our dividend for the upcoming 4 quarters. And at that time, in October, given the strong performance of our business and good visibility into next year, the likelihood of a higher dividend being declared is a good one. And so back to your question, about what do we do with our cash. And the answer to you is we will continue to return to our shareholders. And for us, the primary mean is through our dividend payments.

Our next question is from the line of Gokul Hariharan of JP Morgan.

Congrats on the great results. First of all, Wallace or Riyadh, could you talk a little bit about the SSD controller market, you’re growing at almost 100% in the first half, looks like the growth rate is still going to continue around the same pace. How much of that is the volume growth? How much of that is pricing roughly? Are we still looking at average ASP per SSD controller in the $4.50 to $5 range? And could you also give us a bit of context in terms of how much market share you have of your addressable market in SSD controllers, in consumer SS controllers?

So we will continue to grow our client SSD controller business. We outperformed in the market growth. But we cannot comment regarding ASP dollars, but why we can assure you, the PCIe Gen3 is higher than SATA controller, the PCIe Gen4 also higher than PCIe Ge3. So we definitely expect next year because of strong growth for our PCI Gen4. So every ASP for client controller should go higher. Regarding the market share, we believe, for last year, we are around between 25% to 30% market share this year will grow 5% to 10%. So we roughly -- it’s around 35% to 40% range. We have ambition to grow beyond 40% and just demand. It’s really not depends. It depends how quickly we can build a more R&D team and to serve more demand, especially our NAND makers.

Okay. So is it fair to assume that most of the growth this year is coming from units and a little bit of it is coming from mix improvement, not really price.

Also from the mix price improvement.

Okay. Maybe move on to the second question. I think you talked about M&A. It feels like one of the problems, I think that the market has in terms of evaluating Silicon motion is that the addressable market is still primarily SSD controller, which I think at least is this limited TAM in terms of units, but obviously, there is ASP upgrade. Could you talk about any of the initiatives that silicon motion is doing to potentially address some newer addressable market, either an adjacency or something else that you have in mind given that you’ve executed extremely well in the current SSD controller and eMMC market?

Gokul, we’re doing really well in the client device market, right? So in this part of the market, SSDs already account for 60%, 65% last year. We’ll probably be up to 75%. But clearly, there is a cap in terms of what’s addressable. Same thing with UFS in smartphones. There’s still a lot of upside opportunity there. But again, there is a natural cap. The opportunities that are coming incremental to the client device and to the smartphone for us includes a couple of pieces. The first piece is our enterprise SSD controller market. We’ve -- year-to-date, we’re just getting to our first million milestone. We have our upcoming Gen5. We’re still executing with our enterprise-class Gen 4. So this is a huge blue sky opportunity for us. That will be a big piece of how we continue to grow rapidly beyond when our client-based devices start plateauing. But additionally, in addition to the enterprise-class of SSD controllers. We also have our eMMC products, where with the NAND flash makers exiting -- beginning to exit the low-density applications, this creates an opportunity for us to step in. And we’re talking about a 1 billion unit plus opportunity with eMMC. And so this is another interesting area for us to step into. Additionally, Wallace also talked extensively about the automotive applications relating to what we can play in. And this is still at a pretty early stage. But already, we’re seeing a lot of design activities by the automotive OEMs and their partners, and we’ve been involved in a lot of these projects.

Let me just add ex some comment is as you see from the business model, traditionally, when a storage product become mature and the NAND maker moving to the new generation and the move into higher density, higher performance. But looking for the eMMC, for example, this is one of a great example today because eMMC, the maximum density, probably 120 gigabyte, majority around 64, 32 or even 16 gigabyte. And there’s the last interest for the NAND maker because manufacturing -- similar. But as a financial return, it’s very limited. However, that is a huge -- because it’s standard. There’s a huge demand from all consumer electronics and growing IoT devices, and we become the seller from merchant controller maker provide solution, right? Our really backlog is at 2x than what we can supply today. So there’s quite a lot of things because we continue to develop new controller supporting upcoming new 3D NAND. So that makes us a unique position. NAND maker probably won’t use their R&D resources for this kind of a trend because this product is mature. Same thing for clients being in the future. And we also have some larger important products to do because really sell revenue is very, very small. We really do not want to talk about it. Going to become very mature, and we will try to talk with the investor analysts because I think Silicon Motion, we are not counting on just a few controller, we have a much bigger ambition than where we are today.

Last question is from the line of Matt Bryson of Wedbush Securities.

So the prominent pushback or concern I hear from investors around SMI is probably to the cyclicality of end markets for NAND. So whether it’s PCS, handsets, what have you? Wallace, I think what you’ve described as a number of secular growth opportunities that are very company specific, whether it’s new Gen4 PCIe customer wins, opportunities you’re just talking about in IoT with the eMMC new UFS customers. Is there any way we look at that order book of $1.5 billion for 2022, you can talk to how much of that incremental how much of those incremental orders are tied to new business versus either existing designs or follow-on design to existing designs? Like any characterization, you could provide that would be very helpful.

So I think in the past couple of years, it looked like our business really not show growth consistency. That’s why a lot of the investors have a concern regarding how stable and how fast the commotion can grow. Now I think we are moving to the more healthy business model, all our sales revenue this year is designing from last year or 2 years ago. And while we are working on today is working for next year and beyond next year and 2024. So that’s why the book we have is very, very stable. That’s really doesn’t need any new design that happen today. And that’s why the order book is very rock solid. And I’m pretty sure they will pile up to even higher number by end of this year. And our really main goal is to secure more wafer and such we can fulfill the demand from many, many customers. Some are very, very important project, very, very critical, not just for PC, not just for smartphone, not just for consumer electronic devices, all see the some new innovation. We do have quite a lot for automotive sector. We really haven’t -- really speak for. But I think we have a very diversified product portfolio. We have very strong, very broad customer base. We have many, many opportunities. Now we really want to leverage our base, our technology product and try to have a more manufactural capacity and to fill the demand. And that we think our growth is very, very solid consistent and the market trend favors Silicon Motion and our customers gain market share. That’s a fact.

Now, I’d like to hand the conference back to Mr. Wallace Kou for closing remarks. Please go ahead, sir.
