Thank you and good morning everyone. Welcome to Silicon Motion’s fourth quarter 2023 financial results conference call and webcast. Joining me today is Wallace Kou our President and CEO. Wallace will first provide a key overview of our key business developments and then I will discuss our fourth quarter results and outlook. Following our prepared remarks, we will conclude with Q&A session.

Before we get started, I'd like to remind you of our Safe Harbor policy which was right at the start of this call. For a comprehensive overview of the risks involved in investing in our securities please refer to our filings with the U.S. Securities and Exchange Commission. For more details on our financial results, please refer to our press release, which was filed on Form 6-K after the close of market yesterday. This webcast will be available for replay on the Investor Relations section of our website for a limited time.

To enhance investor's 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 manner 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.

As we have previously shared, Silicon Motion filed its Notice of Arbitration against MaxLinear for the willful material breaches of the merger agreement that was signed on May 5, 2022. The company is seeking payment of the termination fee of $160 million, substantial damages, interest, and costs. The company filed its Notice of Arbitration claim against MaxLinear in the Singapore International Arbitration Center on October 5, 2023. The arbitration process is confidential, and we will therefore not be commenting further on this matter today. With that, I will turn the call over to Wallace.

Wallace C. Kou

Thank you, Jason. Hello, everyone and thank you for joining us today. We are pleased by the steady recovery across our business throughout 2023, with fourth quarter revenue and gross margin exceeding expectations. We benefited in the quarter from stronger demand from both our SSD and eMMC+UFS controllers and saw pricing and mix improved to drive stronger gross margin improvement for our business than originally expected. More importantly, our technology leadership in controller and our unwavering engagement with our customers, both flash makers and module makers has laid the foundation for strong 2024 growth despite only modest growth expecting in the PC and smartphone device markets, driven largely by our ongoing share gains with our customers.

Over the past six months, we have been busy making organizational changes to better position Silicon Motion for the future. We restructured our business to better engage in a new opportunity in the market and spend a lot of time reengaging with the customers to win back their confidence in us as a long-term partner. As you saw, we formed two new business units, client and automotive storage, CAS, and our enterprise storage and display interface solution, the SDI Groups. Our new organizational structure allows us to be more focused on each segment, to have dedicated industry veterans as the leader enable our team to be more agile and responsive to the market and to better engage with customers and anticipate their need with truly differentiated high-performance and classify solutions.

We are seeing the successes of this already as our CAS Group have been increasing share as our customers by winning significant new designs with both flash makers and module makers for the PC, smartphone, automotive, industrial, and other markets. Our ASDI Group has also made incredible progress with some untitled product in a short amount of time securing more than a dozen sampling customer ready. With these changes, we are better positioned than ever before and look forward to demonstrating the ongoing strength of our business to our investor each quarter.

Now let me move into our business and give you an update on the NAND market dynamic we are seeing today and what we are expecting for 2024. Pricing for NAND Flash has been steadily increasing and expected to continue to improve throughout 2024 and into 2025. NAND makers are being disciplined in their production and limiting output, resulting in higher NAND flash prices. Demand is also expected to pick up this year as both the smartphone and PC markets will grow modestly after two years of meaningful decline in unit shipments. While higher pricing may limit the activity we typically see from our module maker customers, many have pre-bought low-cost NAND in the second half of last year, and we have secured significant wins with them for upcoming products this year. We believe our business with module maker will grow this year despite the headwinds created by higher NAND flash prices.

For flash makers, while higher flash prices over the past few months have improved their profitability, most are still facing negative or very low margin, and this is why we are seeing them increasingly focus on profitability. Flash makers need to prioritize their focused investments from developing new generation of NAND to developing storage solutions to satisfy a wide range of end market requirement. These solutions range from high performance to value-oriented using DRAM and as well as utilizing TLC or QLC to serve a broad range of end market need in eMMC+UFS, client SSD, embedded enterprise and industrial applications. We are seeing flash maker focus on their own effort on leading-edge, high-performance solution where margin and profitability tend to be highest and they are turning to us as a partner of choice to help bolster their portfolio with high-performance, lower-cost solutions, utilizing their latest generation of high-performance, high density NAND to serve a broader range of market requirements.

Our progress with our flash maker partner over the past year has resulted in strong backlog of new wins across all our product groups that will drive meaningfully higher share and faster growth this year and lay the foundation for strong long-term growth. We continue to grow our customer relationships and are on track to grow our business with every NAND flash customer we have this year. Our revenue from flash maker expected to grow approximately 50% this year, a design win across our controller program meaningfully throughout 2024.

Turning to our SSD controllers, we take our first PCIe Gen 5 channel controller last quarter and have already secured three flash maker win in this product as well as several module maker wins. This is the first time that flash makers adopt our controller for high-end notebook models. We expect sales of this high-performance controller to begin late this year. We are engaging with other flash makers as well as numerous other module makers expect to win more designs through 2024. Our second PCIe controller will be taped out early in the third quarter this year, and we already have significant interest from both flash makers and module makers for the mainstream Gen 5 solution that are expected to ramp in late 2025. While we are excited by our progress with PCIe Gen 5, it's important to point out that we continue to win significant new programs with several flash makers with older generation interface as well, including two new starter SSD programs, several PCIe Gen 4 SSD including one using next-generation QLC flash on the value of PC OEM market and several USB 3.2 portable SSD projects.

Our QLC controller with our proprietary 3D array and more advanced LDPC for better aero correction and data protection and recovering offer, no compromise solution that maintains high performance and reliability while utilizing the most cost-effective flash to further improve affordability. We are seeing strong traction of QLC controller with both our flash makers and module maker customer and more widespread adoption by PC OEM as well.

Moving on to our eMMC+UFS controller solution. We are taking out our UFS 4.0 solution this quarter and remain on track to ramp with a flash maker customer later this year as well as several module makers targeting the smartphone market. UFS 4 remains a flagship and a premium solution this year and expected to expand into high-end mainstream handset market in 2024 and after. Aligned with win, our solution with our flash maker and module maker customer expected to ramp. UFS 3.1 and 2.2 remains a primary solution for mainstream smartphones this year, and we are seeing continuing strong demand for our current UFS controller with additional flash makers and module makers. We are seeing flash makers focusing on their own internal controller development on the latest flagship generation of UFS, where they get the highest premium for their higher performance solution. As each of UFS generation moved from flagship to mainstream, we are seeing flash maker turning to us to utilize our controller paired with their newest NAND that offer high performance and lower cost, ideal for the mainstream smartphone market. It is a symbolic relationship that has driven our strong partnership with flash makers and driving more win and long-term growth for our eMMC+UFS controller business.

Now let me give you an update on the progress of our MonTitan Enterprise State Development platform. We started sampling MonTitan to customers at the end of last year, and we are excited to announce that more than a dozen customers, many of them Tier 1 end companies ranging from NAND flash makers, hyperscaler, storage solution provider, enabler, as well as module makers are in the process of evaluating the solution. MonTitan’s highly differentiated storage solution provides support of both high-performing TLC SSD as well as high-capacity QLC SSD. We are finding that this ideal balance of performance and features is appealing to customers across all enterprise and data center market segment.

Based on our ability to support a wide range of customer engagement model from the turnkey to layer firmware stack development, MonTitan has raised the asset to an extensive amount of data [indiscernible], speed ideal for a variety of applications, including high-performance edge computing and AI interference and machine learning. We are confident that we will continue to make it grow during the Gen 5 transition into the AI era, and expect to secure a first design win in the next few months and generate clearly revenue by the end of this year.

Overall, I'm excited by the opportunity ahead of us in 2024. Our team dedicating to maintaining our technology leadership and our varying commitment to our customers has enabled us to continue to win socket after socket and positioning us strong share growth this year and beyond. Our position with our flash maker customer has never been stronger with the new design wins are expected to ramp since the beginning of this year. Our module maker customers are coming into 2024 with strong inventory of low-cost NAND and choosing us to help them bring competitive SSD and embedded solutions to the market. We are well positioned to continue to further strengthen our design pipeline in 2024 to drive growth in 2025. Now let me turn the call over to Jason to go over our financial results and outlook.

Jason Tsai

Thank you, Wallace and good morning, everyone. I will discuss additional details of our fourth quarter results and then provide our guidance. Please note that 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 fourth quarter, we grew sales 17% sequentially to $202 million. SSD controller sales grew 15% to 20% sequentially. eMMC and UFS controller sales grew 25% to 30% sequentially and SSD Solution sales decreased 5% to 10% sequentially. Gross margins in the fourth quarter increased to 44.1%, reflecting both better mix and higher ASPs. Operating expenses in the fourth quarter were $61.5 million, $12 million higher than the prior quarter due to higher R&D expenses to support our technology leadership.

Operating margin in the fourth quarter was 13.8%, flat from the third quarter. Effective tax rate in the fourth quarter was 2.3%, a decrease from the 22.8% tax rate in the third quarter primarily due to a tax reversal in the quarter. Excluding this, tax rate would have been 28%. Earnings per ADS were $0.93, 48% higher sequentially. The stock-based compensation in our operating expense, which we exclude from our non-GAAP results, was $5.7 million, and we had $369 million in cash, cash equivalents, restricted cash, and short-term equivalents -- short-term investments at the end of the fourth quarter compared to $350.3 million at the end of the third quarter. Inventory increased sequentially in the fourth quarter to $217 million from $199 million in the third quarter.

Now let me turn to our first quarter and full year 2024 guidance and forward-looking business trends. For the first quarter, we expect revenue to be down 10% to 15% sequentially to approximately $172 million to $182 million. We expect SSD controller sales will decline slightly in the first quarter and eMMC and UFS controller sales will decrease. First quarter gross margin is expected to be in the range of 44% to 45%. First quarter operating margin will be in the range of 10.5% to 11.5%. First quarter effective tax rate to be approximately 19% and in the first quarter, we expect stock-based compensation and dispute-related expenses to be in the range of $6 million to $7 million.

For the full year 2024, revenue will increase 20% to 25% to $765 million to $800 million. Gross margin is expected to be in the range of 45% to 47%. Operating margin should be in the range of 14.7% to 16.7%, and our effective tax rate for the year is expected to be approximately 19%. Full year stock-based compensation dispute and related expenses will be in the range of $31 million to $33 million.

Let me provide some additional color on our first quarter and full year expectations. As Wallace mentioned, we are making strong progress with our flash maker customers. We have a strong pipeline of design wins and are positioned to gain meaningful share this year. We expect our revenue from all of our flash maker customers will grow in 2024 and to increase approximately 50% this year. In addition, we have high visibility that two additional flash makers will be ramping new projects with us this year in eMMC and UFS and in SSD controllers, and we will be able to grow revenue from each of these flash makers very meaningfully.

We expect normal seasonality to impact our business in the first quarter but are confident that we are well positioned to grow sequentially throughout the rest of the year based upon our strong backlog of wins and project ramps. We expect to see consistent improvement in our gross margins this year driven by better mix towards newer generation interfaces in our eMMC and UFS and SSD controller sales, a number of new projects ramping, and overall pricing starting to normalize and improve. For operating expenses, we'll continue to invest in maintaining our technology leadership in the market, including the tape-out of two 6-nanometer controllers, one in Q1 for UFS 4 and one in Q3 for a second PCI Gen 5 SSD controller. This will lead to elevated operating expenses in those quarters. This concludes our prepared remarks. We'll now open the call for your questions.

Question-and-Answer Session

Operator

[Operator Instructions]. First question comes from the line of Mehdi Hosseini from Susquehanna International Group. Please ask your question.

Mehdi Hosseini

Yes, thanks for taking my question. I have two. Wallace, can you help me understand what you're seeing in SSD Solutions business segment, I understand that your continued traction with flash makers and a new product ramps that are more focused on SSD controller and the smartphone, but could you give us a feel for SSD Solution and whether you would be able to actually slow down the decline in revenues here? And I have a follow-up.

Wallace C. Kou

I think our SSD Solution in Ferri has been stable, and we are seeing a strong pipeline of win. I think for Q4 revenue decline due to some of multi-customer see the inventory pile-up and we do see 2024, we have accumulated more design. But we see we have a stronger growth in 2025 from an automotive customer for our Ferri product.

Mehdi Hosseini

Okay, great. And your 2024 guide is very encouraging. You are also ramping a 6-nanometer takeout. I understand what's driving the OPEX increase. I also look at your cash, you have almost $10 of net cash per share. Your just operations should help with additional cash generated, you sound very confident, why not revisit the capital return, especially with the buyback, especially with the investors that have been patient, any thoughts, any color here would be appreciated?

Jason Tsai

Yes, thanks for the question, Mehdi. Look, that's a good question. If we look at our capital allocation program constantly, that's something we review with our Board regularly. We have the dividend policy that we've been paying for a very long number of years with the exception of when we were in the acquisition process. Strategy behind the dividend, as you know, has been always to set it at a level that's comfortably affordable and we'll continue to evaluate going forward, whether to increase the dividend in a future time as business continues to scale and cash flow increases longer term. In terms of things like a share repurchase, as you know, our share repurchase program in the past has been opportunistic. We do not have a program in place today, but the Board is always evaluating ways of returning cash to shareholders and share repurchase is something they'll continue to look at.

Mehdi Hosseini

Thank you.

Operator

Thank you for the questions. One moment for the next questions. Next question comes from the line of Quinn Bolton from Needham. Please go ahead.

Quinn Bolton

Hey guys, congratulations on the results and outlook. Thanks for taking my questions. I wanted to follow up, Wallace on your comments. Very encouraging to hear that you'll grow with every NAND manufacturer in 2024. But I think one of the concerns we've heard from investors is that as UFS 4.0 becomes mainstream, that one of your customers that's in-sourced, UFS 4.0 that may be a headwind more in 2025 than 2024. And so I'm not trying to get you to give guidance for 2025. But overall, would you expect your business in aggregate with NAND vendors to continue to grow in 2025 as UFS 4.0 becomes more mainstream? And then I got a follow-up.

Wallace C. Kou

Yes, we believe we definitely we can continue to grow from our mobile controller for both UFS and eMMC. As you know very well, the UFS 4.0 has still remained the high end for 2024 and 2025 and probably will go to mainstream up to second half of 2026. And we have a very strong UFS 3.1, 2.2 today, not only for existing NAND partner but also winning one to two additional NAND maker business and going to ramp in 2024 and 2025. In addition, we also see NAND makers, they focus on the new development. So when UFS 4.0 becomes mainstream, their R&D is focused on UFS 5.0 development and sometimes outsourcing the new UFS 4.0 project to Silicon Motion because our new laser controller can capture the latest new generation high-performing I/O NAND with higher density NAND. So that will become much more attractive and value add to our NAND partner, extend the product life cycle. So we see our position very well with NAND maker as well as growing module maker who are moving from eMMC to UFS.

Jason Tsai

And I think also that it's becoming a much more diversified business. It's no longer really driven by one customer. We have a multitude of flash makers and module makers that address the smartphone market all very effectively. And so as we ramp up with these new flash makers and module makers, we're confident that we can continue to grow this business long term.

Quinn Bolton

Great. My second question is more a clarification about the two new NAND vendors that ramp this year. Can you give us any color, is that specifically on the eMMC UFS business, is it across both mobile as well as the SSD business, just any color? And then, Jason, just a quick looks like OPEX for the full year probably comes in at about $240 million or on average about $60 million a quarter. I know there's some tape-outs in Q1 and Q3 that will probably increase R&D in that -- in those quarters. But is that sort of $240 million not the right range to be thinking about for OPEX in calendar 2024? Thank you.

Wallace C. Kou

The two NAND makers, I think, really one is for UFS, one for eMMC, but we are continuing looking for engagement with the NAND makers.

Jason Tsai

Yes. And for OPEX, I think -- yes, I think it's in that range. $230 million to $240 million is probably the way to look at it.

Quinn Bolton

Perfect, thank you.

Operator

Thank you for the questions. One moment for the next question. Next question comes from the line of Gokul Hariharan from J.P. Morgan Chase. Please go ahead.

Gokul Hariharan

Yeah, hi. Thanks for taking my questions. First question is on enterprise, given that you have -- you are getting pretty good traction with your new product and you also reorganized the organization to focus more on enterprise. Wallace, could you give us a little bit more color on how big is the enterprise addressable market for Silicon Motion, what is something that you can really achieve over the next maybe three, four years in terms of the enterprise traction? And could you also give us a little bit of color in terms of what kind of design wins are you getting, are you getting more design wins on like core storage products, or is it like making OEMs and hyperscalers, is there any mix in terms of where you're getting the payments, maybe you will give us a little bit more color on the enterprise addressable market?

Wallace C. Kou

So it's a very good question. I think that we are seeing very good traction today as we continue to sample and go through the qualification process with these Tier 1 customers and by a dozen customers from U.S. and to Taiwan, China. And I cannot give you the quantize number, I think by end of 2024, we'll have meaningful revenue. We have much bigger revenue in 2025 and 2026. The reason we get traction not only the standard B&G, we're gaining momentum because the high-performance and all the number index that exceed expectation, but also we get a traction due to the QLC SSD coming into the data center. And then the -- this is for twofold. One is FTP standard for QLC, also Zone NAND safer QLC in China. I think U.S. one customer is also very interested for space. So that makes us a very differentiated compared with conventional solution. Due to the AI server demand and AI demand, I think Gen5 SSD become much more attractive. So this is a similar our demand, and that's why many customers will qualify our Gen 5 solution.

Gokul Hariharan

Got it, thank you very much. My next question is more near-term. For 2024, you have a 20% to 25% revenue guidance. Could you give us some color on how you expect client SSD to grow and mobile to grow? And within mobile, recently, we are hearing some concerns about the end of restocking for some of the Chinese customers. Are you seeing the China, the smartphone customers being a little bit more conservative in terms of procurement in the near-term?

Wallace C. Kou

Yes. I think for Client SSD, last year, our market share -- global market share is around 25%, 26%. We believe this year we will grow to 30% to 32% range because total overall SSD number overall will grow another probably 10 million to 20 million for global unit shipment. For mobile, we will grow faster and stronger because we have more customers in the pipeline not only the existing NAND maker, they continue to grow compared with last year, but also we have two additional NAND maker joined the group to grow. And module maker, we see they will grow even stronger. And we also have a platform development with both Qualcomm and MediaTek. We also have direct engagement with smartphone maker to strengthening our position and technology and pacing for 2025 growth.

Gokul Hariharan

Okay, got it, thank you.

Operator

Thank you for the questions. One moment for the next questions. Our next question comes from the line of Anthony Stoss from Craig-Hallum. Please ask your question.

Anthony Stoss

Thank you. Jason, I was trying to write as fast as I could. On the tape out commentary, could you just break that out again by quarter and kind of the cost that you expect for the quarter? And then I had a follow-up for Wallace.

Jason Tsai

Yes. So we're expecting to tape out our UFS 4 6-nanometer controller here in the first quarter, and then we'll tape out our second PCI Gen 5 controller early in the third quarter. So that's going to result in more elevated OPEX kind of similar to what you saw here in the fourth quarter for each of those two quarters. And then in Q2 and Q4, that should revert back down to a more normalized level because of those -- because those peers don't have the tape-out. Those tape-outs as we have said in the past, are typically north of $15 million in terms of total development and investment cost for us. So during the quarter, where they're taping out, it's certainly a big step up on the OPEX.

Anthony Stoss

Okay. Got it. And then Wallace, I'd love to hear a little bit more last quarterly conference call, you talked about a new Korean NAND maker coming on as a customer. I'm curious to your view on how quickly they could wrap and could they be a, let's say, a top three customer in 2025?

Wallace C. Kou

We cannot comment individual NAND maker customers about the revenue, but we definitely look forward to stronger engagement and broaden our product line and design win. I think we would start looking forward to embrace the NAND maker who really can outsource more projects to Silicon Motion, and will add value to them. I think that 2024, 2025, they are really a good timing for us to show our technology and serve our NAND maker, select their R&D extension and looking forward to more exciting results. And we will definitely rollout this year.

Anthony Stoss

Okay. And if I could sneak in one more on your MonTitan, so you talked about having secured one design win. Can you give us any color on if it's a data center hyper scaler, NAND maker, and then how quickly do you think you can secure additional out of those 12 that have sampled?

Wallace C. Kou

We cannot comment the customer and the type, but I think with Tier 1 customers and with that, we believe we will secure the second one in the second half of 2024. So I think we're confident to win at least two Tier 1 customers by end of 2024.

Anthony Stoss

Very good, thank you.

Operator

Thank you for the questions. Next question comes from Craig Ellis from B. Riley Securities. Please ask your question.

Craig Ellis

Yeah, thanks for taking the question. Wallace, I wanted to start with you and follow-up on some of the outsourcing questions from the call, but also really continue the conversation that you and I have had over the last couple of years. So I think we both expected that there would be an increase in outsourcing from NAND customers. And the question is this, as you look across the increase in activity that you've observed over the last 12 months or so, can you characterize how extensive that is from OEMs that are maybe just doing one or two new products to much more wholesale changes, what's happening on the continuum a little bit to a lot, and how much of that is baked into the guidance that you and Jason have given for calendar 2024? And then I had a couple of follow-ups. Thank you.

Wallace C. Kou

I think the -- as you can see through the 2023 it was a difficult year for all the NAND makers because the weak demand and the oversupply, the NAND price declined sharply and nobody really make any planning. Everybody is margin negative. And we are able to gain share because I think we are treated view, recognize the extension of NAND makers on R&D. So that's why we have been developed such relationship recognition, trust, and respect for the past 15 years. And we're capable and handling. So NAND makers, their focus now is not focused on market share. They focus on profitability. So they are not either invest more CAPEX in the NAND capacity. They only invest the technology they want to deliver. So their focus on the development between the high end, more value, we can maximize the profitability they can get. And the mainstream [indiscernible], they will try to also to third party like Silicon Motion, which we can help them and diversify and bring a more portfolio offered to the very end customer. So this is the idea we bring to the table, and we see more and more outside opportunity from NAND maker when they make a business decision, they tend to go to the third party like Silicon Motion.

Craig Ellis

Got it. And then the follow-up question is just a continuation. What are the things that you're looking at that will indicate that this is not only a trough cycle reaction from NAND OEMs, but through the sweet spot of the cycle and towards the peak of the cycle, they would sustain this level of outsourcing or perhaps even grow it? And then the follow-up is for Jason. Jason is MonTitan ramps in calendar 2024, how should we think of the gross margin implications relative to corporate average?

Wallace C. Kou

We see this cycle because now NAND well-being shortage. So NAND maker the careful to value all the priority inside the company. Every NAND maker may have a different strategy, and we cannot comment for that. But we believe this cycle will continue until middle of 2025 or late 2025, when supply demand reached balance and NAND makers start to invest more about the CAPEX and to meet the higher demand.

Jason Tsai

And I also think that -- I think to your question about how much of this outsourcing is temporary versus more of a structural shift. We have wins going into 2025 and further out. So I think this isn't something where they were just using us for a short-term stop gap. This is something where we're building much more substantial long-term relationships with them. In terms of the MonTitan revenue ramp and margin impact, that's not going to expect it to happen until late into Q4 -- late into 2024, excuse me, in Q4. So it's too early to say what impact it will have. More meaningful ramp in 2025 and certainly, as we have better visibility around that, around timing of wins and scale of the wins, we'll be able to provide more color. But right now, it's a little too early to talk about the impact of both revenue and margins at this point.

Craig Ellis

Got it. And the gross margin color on calendar 2024 guide was quite helpful. Can you talk about the visibility that you have, Jason, to gross margins ultimately reattaining that more normalized 50% level?

Jason Tsai

Yes. I think we're feeling pretty good about that just given the mix of new products, new projects, new technologies that are coming to market that we already have strong design win and pipeline for. As each day passes, we're also seeing these new engagements bring with them healthier pricing levels at healthier margins, and we're certainly working on our own back end and production to also improve costs as well. So I think we're on a good track here and the guidance that we provided, we believe that it's attainable.

Craig Ellis

Thanks Wallace, thanks Jason.

Operator

Thank you for the questions. Our next question comes from Suji Desilva from ROTH MKM. Please go ahead.

Suji Desilva

Hi Wallace, hi Jason. Congrats on the good guidance here. You talked about the module makers securing lower-cost NAND in late 2023 that they're selling through now. Can you just talk about the behavior you'd expect as that lower cost NAND gets worked through and how they respond, would they then look to market conditions or just any thoughts there on how that might impact the financials after that gets worked through?

Wallace C. Kou

Most of our leading module makers I think they have been in the market for a long time. So they understand NAND price trend. So they procure a very large amount of NAND through last August to November. So that really is prepared for NAND price up. They understand NAND price, NAND will be in shortage and NAND price will go continually throughout the entire 2024. So they're procuring advance and to balance their cost they will continue to buy some of NAND this year. But product mix and NAND different pricing makes them to be more competitive to compete with other module makers.

Okay, alright, thank you Wallace. And then my other question is on the MonTitan as it ramps up. Is this the right way to think about that, that maybe some of the AI servers out there, great opportunity for attach rates and content increases of MonTitan or is that not the right framework for what might be...?

Wallace C. Kou

I cannot comment on that, but I think the current demand is in the very wide range from the hyperscalers and from AI server, from all-flash array, from conventional servers. So I think we're definitely looking forward to -- but the more important is a Tier 1 customer who have a really good volume, and we believe we can -- we have secured one. We're looking forward to see your second one by second half of 2024.

Suji Desilva

Okay, that’s very helpful Wallace. Thanks.

Operator

Thank you for the questions. [Operator Instructions]. We have a follow-up questions from Mehdi Hosseini from Susquehanna International Group. Please go ahead.

Mehdi Hosseini

Yes, great, thanks for the follow-up. Jason, I understand the 6 nanometer tape-out is going to keep your R&D in the $47 million to $48 million a quarter this year. Should we expect additional tape-outs next year, or in other words, should R&D stay at these elevated levels into 2025 or would it taper off?

Jason Tsai

I think we'll continue to invest here. I think it's a little too early for us to comment about what 2025 OPEX looks like at this point. But obviously, it's important for us to continue to invest, to continue to stay ahead. We tape out a 6 nanometer because it's what we need to do. The technology requirements for performance and power, you can only get both of those to the right levels when you go down to this lower process geometry. I think there are options for us to look at ways of reducing tape-out costs and foundry costs longer term that we're exploring. So stay tuned as we have more to share on that we will. But certainly, our goal here is to continue to invest, but invest responsibly and try to bring the cost down as much as we can, but still maintain our technology leadership.

Mehdi Hosseini

Sure, that's fair. Ultimately, we're just trying to figure out if the company is still targeting mid to high 20% operating margin and OPEX is a factor here. So any thoughts on the longer-term operating margin target since...?

Jason Tsai

Yes, that hasn't changed. I think if you take a look at our business in the past, we are typically a 48% to 50% plus gross margin company and operating margins in that 25% to 30%. There's nothing fundamentally different about our business today that says that, that's not an achievable target for us longer term.

Mehdi Hosseini

Okay, very helpful. Thank you.

Operator

Thank you for the questions. One moment for the next questions. We also have a follow-up question from Craig Ellis from B. Riley Securities. Please go ahead.

Craig Ellis

Thank you for taking the follow-up. Wallace, you mentioned the company has a collaboration with both MediaTek and Qualcomm. And I was hoping you could comment a little bit further on that, both on the duration of those two partnership engagements and two, the nature of them, are you a reference design partner for those solutions, and if so, to what extent, and to what extent have those been part of UFS revenues in the past, and are they expected to be in 2024 and 2025? Thank you.

Wallace C. Kou

It's important for our new products and to qualify on leading SoC provider, like the Qualcomm MTK for the mobile platform. And then normally, we have direct engagement also through our customer, joint qualification. So they help us to resolve some issue during the preproduction qualification. So this is a joint prequalification and help us to gain confidence for our quality for firmware as well as ASIC. And we also and what we serve Qualcomm for automotive platform qualification. So they extended our product line like Ferri and MediaTek and other NXP. So this is the platform and platform engagement to help accelerate our product readiness, also help our customers to end the production sooner.

Craig Ellis

And how material are those relative to the revenue that we've been seeing and that you would expect to see in 2024?

Wallace C. Kou

I cannot quantize the numbers, but I tell you it's very helpful and our company put a big effort for platform qualification and team and dedicated to help our product line.

Craig Ellis

Thanks Wallace.

Operator

Thank you for the questions. Next up, we also have a follow-up questions from Gokul Hariharan from J.P. Morgan Chase. Please go ahead.

Gokul Hariharan

Yeah hi. I had one question on AI. Thanks Wallace, you did highlight the AI adoption on the enterprise side. Could you also talk broadly on what happens when you have more adoption on edge devices, especially most of your PC and smartphone customers are launching AI-enabled PCs and smartphones this year and probably more next year. What does it do to NAND flash content and what does it do to your controller ASPs or controller specs?

Wallace C. Kou

So these are very good questions. Naturally, not only us, all the NAND maker, I think have spent probably at least half year looking forward to how the AI will impact for storage solution and what a controller maker need to do to improve our value and enhance AI application. So there's a lot of exciting applications for AI PC. You're looking from the Intel, AMD, the SoC, also Qualcomm and NVIDIA coming provide the solution. There are also third-party for AI SoC for PC, but not for the notebook, but for desktop and for PC workstation. So we are involving for what our company is for enterprise AI, the SSD probably because the enterprise -- the server AI is more important for compute. So it's solution is really a system role. So the regular latency and sequential results is very critical and to supporting and obviously all the AI server requirement.

But for the AI PC, that's a different story because you cannot use HBN for the PC. You cannot use a very, very high density and limited density for DRAM. So the -- swapping become very critical. So several technologies, several requirement is really neither SSD controller and a solution to provide to allow to make the Edge AI to be more meaningful and more practical. And I cannot go to detail. I'd just say, this is all the area we are looking for to add value and study. I think all NAND makers and leading control makers are looking for to provide solution and be part of the Edge AI trend.

Gokul Hariharan

Okay, thank you very much. And second, on PCIe Gen 5, could you talk a little bit about the pricing uplift you're expecting as you go from PCI Gen 4 to PCI Gen 5, I remember I think you talked about significant premium in the last call. Could you talk a little bit about what you're seeing in the market for the flagship products and how that is likely to shape out as we get into more mainstream PCI Gen 5 products towards next year as well?

Wallace C. Kou

I think, I cannot give you exact number, but our high-end PCI Gen 5 channel controller is about two times of PCIe Gen 4 controller today. We are very exciting to see our high-end PCIe Gen 5 controller adopted by three NAND maker. We believe there will be additional join in later this year. So this is very important for us to expand our market share for notebook, for PC OEM, as well as we see the increase in our sales revenue as well as margin. And this is a very important milestone. And the PCIe Gen 5 and the high-end controller can also be adopted by the server for boot storage. And I think there's a trend we're seeing and not just for notebook, but PC for workstation for gaming PC that will be our top high-end PCIe Gen 5 channel controller.

Operator

Thank you for the questions. With that, I would like to hand the call back to the management for closing remarks.

Wallace C. Kou

Thank you, everyone for joining us today and for your continued interest in Silicon Motion. We will be attending several investor conferences over the next few months. The schedule of this event will be posted on the Investor section of our corporate website. Thank you, everyone for joining today. Goodbye for now.

Operator

That does conclude today's conference call. Thank you for your participation. You may now disconnect your lines.
