The company filed this 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.
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, plus UFS controllers, and saw pricing and mix improve to drive stronger gross margin improvement for our business than originally expected. More importantly, our technology leadership in controllers 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 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 the new opportunity in the market and spend a lot of time re-engaging with 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, ESDI groups. Our new organizational structure allow us to be more focused on each segment. To have, dedicated industry veterans as a leader enable our team to be more agile and responsive to the market and to better engage with customers and anticipate their needs with truly differentiated high performance and cost-effective solutions. We are seeing the successes of this already as our CAS group have been increasing share with our customers by winning significant new designs with both flash maker and module maker for the PC, smartphone, automotive, industrial, and other markets.
Our ESDI group has also made incredible progress with MonTitan product in a short amount of time, securing more than a dozen sampling customers already. With these changes, we are better positioned than ever before, and look forward to demonstrating the ongoing strength of our business to our investors each quarter. Now, let me move into our business and give you an update on the NAND market dynamics 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 maker need to prioritize their focus and investment from developing new generation of NAND to developing storage solution to satisfy a wide range of end market requirement.
These solutions range from high performance to value-oriented, using DRAM and DRAMless, as well as utilizing TLC or QLC to serve a broad range of end market need in eMMC for the 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. They are turning to us as a partner of choice to help bolster their portfolio with high performance, lower cost solution, utilizing their latest generation of high performance, high density NAND, to serve a broader range of market requirement. Our progress with our flash maker partner over the past year has resulted in strong backlog of new wins across all our products 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, as design win across our controller program ramp meaningfully throughout 2024. Turning to our SSD controllers, we taped out our first PCIe Gen5 8-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 maker adopt our controller for high-end notebook models. We expect sale of this high-performance controller to begin late this year. We are engaging with other flash maker as well as module makers—numerous other module makers expect to win more designs through 2024.
Our second PCIe Gen5 controller will be taped out early in the third quarter this year, and we already have significant interest from both flash maker and module maker for the mainstream Gen5 solution that's expected to ramp in late 2025. While we are excited by our progress with PCIe Gen5, it's important to point out that we continue to win significant new program with several flash maker with older generation interface as well, including two new SATA SSD programs, several PCIe Gen4 SSDs, including one using next-generation QLC flash in the value PC OEM market, and several USB 3.2 portable SSD projects. Our QLC controller with our proprietary 3D RAID and more advanced LDPC for better error correction and data protection and recovery offers no compromise solution that maintains high performance and reliability by 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 plus UFS controller solution. We are taping 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 4.0 remains a flagship and the premium solution this year, and expected to expand into high-end mainstream handset market in 2024 and after. Aligned with when our solution with our flash maker and module maker customer expected to ramp, UFS 3.1 and 2.2 remains the primary solution for mainstream smartphone this year. And we are seeing continuing strong demand for our current UFS controller with additional flash makers and module makers.
We see flash makers focusing on their own internal controller development on the latest flagship generation of UFS, where they get the highest premium for their high-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. That is a symbiotic relationship that has driven our strong partnership with flash maker and driving more win and long-term growth for eMMC, for UFS controller business. Now, let me give you an update on the progress of our MonTitan Enterprise SSD 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, hyperscalers, storage solution providers, enablers, as well as module makers, are in the process of evaluating the solution. MonTitan highly differentiated storage solution provides support of both high-performance 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 makers fact market segment.
Based on our ability to support a wide range of customer engagement model from the turnkey to layer firmware stack development, MonTitan accelerates the access to an extensive amount of data at Gen5 speed ideal for a variety of application, including high performance, edge computing, and AI inference and machine learning. We are confident that we will continue to make an inroad during the Gen5 transition into the AI era. Expect to secure a first design win in the next few months and generate early 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 unwavering commitment to our customers have enabled us to continue to win socket after socket and positioning us strong share growth this year and beyond.
Our positioning with our flash maker customer has never been stronger, as new design wins are expected to ramp significantly 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.
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. The 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%-20% sequentially, eMMC and UFS controller sales grew 25%-30% sequentially, and SSD solution sales decreased 5%-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 is 13.8%, flat from the third quarter. Effective tax rate in the fourth quarter is 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. 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%-15% sequentially to approximately $172 million-$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 margins is expected to be in the range of 44%-45%. First quarter operating margin will be in the range of 10.5%-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-$7 million. For the full year, 2024, revenue will increase 20%-25% to $765 million-$800 million. Gross margin is expected to be in the range of 45%-47%. Operating margin should be in the range of 14.7%-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-$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 fourth, 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 just 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-nm controllers, one in Q1 for UFS4 and one in Q3 for our second PCIe 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.
Thank you. We now begin the question and answer session. If you'd like to ask a question, please press star one, one and wait for your name to be announced. If you'd like to cancel your request, please press the pound or hash key. One moment for the first question. The first question comes from the line of Mehdi Hosseini from Susquehanna International Group. Please ask your question.
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 your continued traction with flash makers and the new product ramps that are more focused on SSD controller and the smartphone. But, if you could 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.
I think our SSD solution Ferri has been stable, and we are seeing a strong pipeline of win. I think for Q4, revenue declined due to some of our automotive customers see the inventory pile up, and we do see 2024, we have accumulate more design. But we see we have stronger growth in 2025 from automotive customer for our Ferri product.
Okay, great. And your 2024 guide is very encouraging. You also ramping a 6-nm tape out. 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 investors that have been patient? Any thoughts, any color here would be appreciated.
Yeah, thanks for the question, Mehdi. Look, it's a good question. You know, we look at our capital allocation program constantly, right? That's something we review with our board regularly. You know, we have the dividend policy that we've been paying for a, you know, very long number of years, with the exception of when we were in the, acquisition process. The 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 at 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.
Okay. Thank you.
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.
Hey, guys, congratulations on the results and outlook. Thanks for taking my question. 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, you know, one of your customers that's in-sourced UFS 4.0, you know, that may be a headwind more in 2025 than 2024. And so, you know, 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.
Yes, we believe we definitely can continue to grow from mobile controller for both UFS and eMMC. As you know very well, the UFS 4.0 still remains 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 1-2 additional NAND maker business and going to ramp in 2024 and 2025. In addition, and we also see NAND maker, they focus on the new development. So when UFS 4.0 become the mainstream, their R&D focus on the 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, higher performance I/O NAND, with higher density NAND. So that will become much more attractive, and that will add to their, to our NAND partner, extended product life cycle. So we see our position very well with NAND maker, as well as growing module maker, who moving from eMMC to UFS.
I think one thing to point out, Quinn, 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.
Great. My second question is more a clarification about the two new NAND vendors that ramped this year. Can you give us any color? Is that specifically on the eMMC UFS business? Is it across both, you know, 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 are some tape outs in Q1 and Q3 that will probably, you know, increase R&D in that, in those quarters, but is that sort of $240 million about the right range to be thinking about for OpEx in calendar 2024? Thank you.
Yeah, the two NAND makers, I think, so really is one is for UFS, one is eMMC, but we are continue looking for engagement with the NAND makers.
Yeah, and for OpEx, I think, yeah, I think it's in that range. $230 million-$240 million is probably the way to look at it.
Perfect. Thank you.
Thank you for the questions. One moment for the next question. Next question comes from the line of Gokul Hariharan from JPMorgan Chase. Please go ahead.
Yeah, hi. Thanks for taking my question. First question is on enterprise. Given that you are getting pretty good traction with your new product, and you also reorganize 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 between OEMs and hyperscalers?
Is there any mix in terms of where you're getting design wins? Maybe give us a little bit more color on the enterprise addressable market.
So it's a very good question. I think that we are seeing very good traction today as we continue sample and go through the qualification process with these Tier 1 customers, and about a dozen customer from U.S. and to Taiwan, China. So I cannot give you the quantified number. I think by end of 2024, we'll have meaningful revenue. We'll have much bigger revenue in 2025 and 2026. The reason we get the traction, not only the standard NVMe, we're gaining momentum because the high performance and all the number index, it exceeds expectation. But also we get a traction due to the QLC SSD coming into the data center. And the... This is for twofold.
One is FDP, standard for QLC, also Zoned Namespace for QLC in China. I think U.S., one customer also very interested for Zoned Namespace. So that makes us a bit differentiate compared with conventional SSD solution. Due to the AI server demand and AI demand, I think Gen5 SSD become much more attractive. So this is simulate all the demand, and that's why many customers interested for qualify our Gen5 solution.
Got it. Thank you very much. For my next question is more near term. For 2024, you have a 20%-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 Chinese smartphone customers being a little bit more conservative in terms of procurement in the near term?
Yeah. I, I think, for client SSD, last year, our market share, took global market share is around 25-26%. We believe this year will grow to 30%-32% range. Because total overall SSD number overall will grow another probably, 10-20 million for global unit shipment. For mobile, we will grow faster and stronger because we have, more customers in the pipeline. And not only the existing NAND maker, they continue grow compared with last year, but also we have two additional NAND maker will join 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 a direct engagement with smartphone maker to strengthen our position and technology and pacing for 2025 growth.
Okay, got it. Thank you. 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, ask your question.
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 per quarter? And then I had a follow-up for Wallace.
Yeah. So we're expecting to tape out our UFS 4.0, 6-nm controller here in the first quarter, and then we'll tape out our second PCIe Gen5 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, you know, 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, where they're taping out, it's certainly a big step up on the OpEx.
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 your view on how quickly they could ramp, and could they be a, let's say, a top three customer in 2025?
We cannot comment individual NAND maker customer about their revenue. But we definitely looking forward to stronger engagement and broader our product line and the design design win. I think we definitely looking forward to embrace the NAND maker who really can outsource more project to Silicon Motion, and we 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 as a select their R&D extension, and looking forward to a more exciting result. And we will definitely follow up this year.
Okay. And if I could sneak in one more on your MonTitan. I see you talked about having secured one design win. Can you give us any color on if it's a data center, hyperscaler, NAND maker? And then, how quickly do you think you can secure additional out of those 12 that have sampled?
We cannot comment the customer and the type, but I think with Tier 1 customer, 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 customer by end of 2024.
Very good. Thank you.
Thank you for the questions. Next question comes from Craig Ellis from B. Riley Securities. Please ask your question.
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, you know, 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 follow-ups. Thank you.
I think, as you can see, through the 2023, it was difficult year for all the NAND makers because the weak demand and the oversupply. The NAND price and declined sharply, and nobody really make any penny. Everybody margin negative. And we are able to gain share because I think we, we are treated view, recognized, become the extension of a NAND maker's own R&D. So that's why we have been developed such relationship, recognition, trust, and respect for the past 15 years. And it's 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 eager invest more CapEx in the NAND capacity. They only invest the technology they want to deliver.
So their focus on the development is through the high-end, more value, and can maximize the profitability they can get, and the mainstream value line, they will try also to third party like Silicon Motion, which we can help them and diversify and bring them more portfolio offered to their end customer. So this is the idea we bring to the table, and we see more and more also an opportunity from NAND makers. When they make a business decision, they tend to go to the third party like Silicon Motion.
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, as MonTitan ramps in calendar 2024, how should we think of the gross margin implications relative to corporate average?
We see this cycle because now NAND will be in shortage. So, NAND maker, they carefully to value all the priority inside the, inside the company. Every NAND maker have 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 reach balance, and NAND makers start to invest more about their CapEx, and to me, the higher demand.
I also think that you know, 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're just using us for a short-term stopgap. 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 gonna 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.
Got it. The gross margin color and calendar 2024's guide was quite helpful. Can you talk about the visibility that you have, Jason, to gross margins ultimately reattaining that more normalized 50% level?
Yeah, 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, you know, healthier pricing levels and 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, you know, the guidance that we've provided, we believe that was, is attainable.
Thanks, Wallace. Thanks, Jason.
Thank you for the questions. Our next question comes from Suji De Silva from Roth MKM. Please go ahead.
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, and how they'd 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?
Yeah. 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 very large amount of NAND through last August to September to November. So that is really is prepared for NAND price up. They understand NAND price, NAND will be in shortage, and NAND price will go up continually throughout the entire 2024. So they procuring in advance, and to balance their cost, they will continue to buy some of NAND this year, but as sure the product makes the NAND different pricing, makes them to be more competitive, to compete with other module makers.
Okay. All right. Thank you, Wallace. And then my other question's 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 creates a opportunity for attach rates and content increases of MonTitan, or is that not the right framework for what might be causing-
I cannot comment on that, but I think the current demand is in a very wide, 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 more important is the Tier 1 customer who have a really good volume, and we believe we can—we have a secure one. We're looking forward to see your second one by second half of 2024.
Okay. That's very helpful, Wallace. Thanks.
Thank you for the questions. Once again, to ask question, please press star one one and wait for your name to be announced. We have a follow-up questions from Mehdi Hosseini from Susquehanna International Group. Please go ahead.
Yes, thanks for the follow-up. Jason, I understand the 6- nm tapeout is gonna keep your R&D in the $47 million-$48 million a quarter this year. Should we expect additional tapeouts next year? Or in other words, should R&D stay at these elevated levels into 2025, or would it taper off?
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, you know, obviously, it's important for us to continue to invest, to continue to stay ahead. You know, we tape out at 6- nm 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, you know, stay tuned.
As we have more to share on that, we will, but certainly our goal here is to continue to invest, but reinvest responsibly and try to bring the cost down as much as we can, but still maintain our technology leadership.
Sure. That's fair, and 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 that longer-term operating margin target since we look-
Yeah, that hasn't changed. You know, I think if you take a look at our business in the past, you know, we are typically 48%-50%+ gross margin company and operating margins in that 25%-30%. There's nothing fundamentally different about our business today that says that that's not an achievable target for us longer term.
Okay. Very helpful. Thank you.
Thank you for the questions. One moment for the next questions. We also have a follow-up questions from Craig Ellis from B. Riley Securities. Please go ahead.
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 to 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.
It's, it's important for our new product and to qualify on leading, SoC provider like a Qualcomm MTK for the mobile platform. And normally, we have a direct engagement also through our customer, joint qualification. So they help us to resolve some issue during the pre-production qualification. So this is a joint pre-qualification, and it help us to gain confidence for our quality for firmware as well as ASIC. And we also work with Qualcomm for automotive platform qualification, so they extended our other product line, like Ferri and MediaTek and other NXP, NXP. So this is a, it's a platform qual- partner and Qualcomm platform engagement, helping to help accelerate our product readiness, also help our customer to enter production sooner.
How material are those relative to the revenue that we've been seeing and that you would expect to see in 2024?
I cannot quantify the numbers, but I tell you, it's very helpful, and our company put a big effort for platform qualification and team, and dedicate to help our product line.
Thanks, Wallace.
Thank you for the questions. Next up, we also have a follow-up questions from Gokul Hariharan from JPMorgan Chase. Please go ahead.
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 AI 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?
So this is very good questions. Naturally, not only us, all the NAND maker I've seen has spent probably at least a half year looking forward to how the edge AI will impact for storage solution and what a controller maker need to do to improve our value and to enhance the AI application. So there's a lot of exciting application for AI PC. You're looking from the Intel, AMD, the SoC, also Qualcomm and NVIDIA coming, provide the solution. They're also third-party independent AI SoC for PC, but not for the notebook, but for desktop and for PC workstation. So we are involving for what our comment is, for enterprise AI, the SSD probably, because the enterprise, the server AI is more important for compute. So its storage solution is really assist, assistant role.
So the regular latency and sequential rewrite is very critical in supporting all the AI server requirement. But for the AI PC, that's a different even story because you cannot use HBM for the PC. You cannot use a very, very high density, unlimited density for DRAM. So the L-in swapping become very critical. So several technologies, several requirement is really need a 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 to say this is all the area we are looking forward to add value and study. I think all NAND maker and leading controller maker are looking forward to provide a solution and be part of the AI edge AI trend.
Okay, thank you very much. And, second, on PCIe Gen5, could you talk a little bit about the pricing uplift you're expecting as you go from PCIe Gen4 to PCIe Gen5? 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 PCIe Gen5 products towards next year as well?
I think, I cannot give exact number, but, our high-end PCIe Gen 5 8-channel controller is about 2x of, PCIe Gen 4 controller today. We're very exciting to see our high-end PCIe Gen 5 controller adopted by three NAND maker. We believe there will be additional joining in later this year. So this is, very important for to expand our market share for notebook, for PC OEM, as well as we see the, the increase our sale revenue as well as, margin. And this is very important milestone. And the PCIe Gen 5 and the high-end controller can also be adopted by the server for boot storage.
I think there's a trend we've seen, and not just for notebook, but PC, for workstation, for gaming PC, they'll be all adopt the high-end PCIe Gen5, Gen5 8-channel controller.
Thank you for the questions. With that, I'd like to hand the call back to the management for closing remarks.
Thank you, everyone, for joining us today and for your continuing interest in Silicon Motion. We'll be attending several investor conferences over the next few months. The schedule of this event will be posted on the Investor Relations section of our corporate website. Thank you, everyone, for joining today. Goodbye for now.
That concludes today's conference call. Thank you for your participation. You may now disconnect your lines.
