Thanks everyone for joining us for FormFactor's fourth quarter earnings call. FormFactor's fourth quarter results were in line with the outlook we provided last November. Compared to that outlook, moderately higher revenue and gross margins were offset by a higher tax rate, producing non-GAAP EPS at the midpoint of the range. As we enter 2024, we continue to operate in an overall demand environment that remains similar to the levels we experienced during the past year, and we expect first quarter results to be similar to those achieved in recent quarters. The relatively stable aggregate demand across our combined served markets is a benefit of FormFactor's diversification strategy and sets us apart from our direct competitors. FormFactor has a broad lab-to-fab product portfolio across foundry and logic, DRAM and Flash probe cards, together with our system segment products. This unique portfolio enables us to compete for business across diverse demand pools at all major customers, producing relatively consistent top line results as we've demonstrated for the past four quarters and which we expect again in the current quarter. Customer investments in growing areas driven by generative AI, like high-bandwidth memory and co-packaged silicon photonics are helping offset the impact of areas that are presently at cyclically low levels, like mobile handsets and PCs and those entering cyclical downturns like automotive and industrial. The stability also enables FormFactor to keep investing in R&D for new product innovation and competitive differentiation, especially in our product road map for advanced packaging applications like chiplets and tiles, high-bandwidth memory and co-packaged optics. It also enables us to invest in capacity and other strategic initiatives designed to produce market share gains and above industry revenue and profit growth when the industry returns to growth, which will enable FormFactor to achieve and then surpass the levels of our current target financial model. Because of the strength and stability of our balanced product portfolio, we can make these investments while maximizing quarterly profitability and protecting our strong balance sheet throughout prolonged periods of industry softness. Turning now to segment level details. DRAM probe cards are an area of current strength, and we expect first quarter DRAM revenue to approach the peak levels experienced in 2021. DRAM strength is being driven by two factors. First, and perhaps surprisingly, we're experiencing strong demand generated by new DDR5 DRAM designs as customers prepare for high-volume production when the eventual DRAM upturn arrives. This provides insight into the unique characteristics of probe card demand. Since probe cards are a device-specific consumable, customized to each individual chip design, early production activity for these new DDR5 designs is driving demand for new probe cards, albeit at lower overall levels and with somewhat greater short-term volatility than we might expect to see in a full-scale cyclical upturn. The second factor behind our strong DRAM outlook is the continuing acceleration in demand from multiple customers for probe cards to test high-bandwidth memory or HBM. Together with the headline grabbing GPUs, HBM is a key enabler for generative AI, and we are forecasting nearly 50% sequential growth in our HBM probe card business in the first quarter. HBM offers a great example of how advanced packaging is driving FormFactor's results. As we mentioned in the past, advanced packaging applications like HBM produce both higher test intensity, which expands the number of probe cards required per good die out and higher test complexity, which raises the performance requirements for each probe card. Each HBM chip is a stack of 8, 12 or even 16 individual DRAM die assembled with advanced packaging processes, such as through-silicon vias and hybrid bonding. To ensure high yields of the stacked DRAM chip, customers probe and test each component DRAM die prior to stacking and probe and test the multi-die DRAM stack at various points during the assembly process, leading to a substantial increase in the overall probe card intensity for good die out. In addition, the technical requirements for HBM tests are significantly more advanced than for standard unstacked DRAM products, involving higher test speeds and more challenging thermal scaling specifications. FormFactor's MEMS-based SmartMatrix probe card architecture meets these advanced requirements, providing significant value to our customers and differentiation for FormFactor. We believe our superior performance capabilities will drive both market share and profitability gains as HBM continues to grow, driven by the accelerating adoption of generative AI. Shifting to foundry and logic probe cards, our largest business, we experienced the expected sequential reduction in the fourth quarter as key customers digested the significant third quarter shipments of probe cards for a major tile-based client PC design and two major high-performance compute designs in the foundry space. We expect similar demand levels for foundry and logic probe cards in the current quarter as customers continue to closely manage their output now that inventories have stabilized at healthy levels in high unit volume end markets like client PC and mobile. Looking further ahead, the adoption of advanced packaging processes like chiplets and tiles by major foundry and logic customers continues to accelerate as they seek to advance their road maps in the face of a slowing Moore's law. As in high-bandwidth memory, advanced packaging and foundry and logic applications again demand both higher test intensity and higher test complexity. The positive impact of this trend, together with the potential for increased compute power and PCs and handsets to support AI at the edge will drive significant growth in the foundry and logic probe card market. As anticipated, we experienced a sequential reduction in Systems segment revenue in the fourth quarter, mainly due to the sale of our FRT metrology business. The Systems business continues to be driven by strong demand for our market-leading test and measurement products for early development of applications like co-packaged silicon photonics and quantum computing. More broadly, Systems is an important element of our diversification strategy as spending in this segment is primarily driven by customer innovation and R&D budgets and is not directly correlated with semiconductor production activity. Co-package optics enabled by silicon photonics remains an important and exciting driver for FormFactor's current systems and future probe card businesses. The transition of silicon photonics from early R&D to low-volume production continues, and we have now installed a CM300 silicon photonic system at the world's leading foundry to support low-volume production, as well as serve as a platform for the co-development of the enhancements needed for high-volume electrical and optical test of co-package optics. As production volumes increase over the next several years, our product road map delivers both systems and consumable probe cards to test these electro-optical devices and improve yields, enabling our customers to seamlessly transition from the lab to the fab. Finally, earlier today, we announced an agreement to divest our subsidiaries in China to Grand Junction Semiconductor, together with a long-term exclusive distribution and partnership agreement. This transaction is designed to adjust our operational strategy in the region in light of export controls that have caused our China revenues to decline over the past several quarters. In closing, we continue to operate efficiently and prudently in what we see as a relatively stable demand environment across our diversified product and technology portfolio. Longer term, we remain excited and confident in the growth prospects for FormFactor in the industry overall, driven by the fundamental trends of semiconductor content growth and exciting innovations like HBM, chiplets and co-packaged silicon photonics. These are trends where FormFactor is well positioned as an industry and technology leader, and we're confident that our investments in R&D and capacity position FormFactor to emerge from the current cyclical downturn a stronger and leaner competitor, enabling us to achieve our target model that delivers $2 of non-GAAP earnings per share on $850 million of revenue. Shai, over to you.

Thank you, Mike, and good afternoon. As you saw in our press release, Q4 revenues and non-GAAP gross margin were at the high end of our outlook range and non-GAAP EPS was at the midpoint of the range. Fourth quarter revenues were $168.2 million, a 2% sequential decrease from our third quarter revenues and a year-over-year increase of 1.3% from our Q4 2022 revenues. Probe card segment revenues were $126.8 million in the fourth quarter, a decrease of $1.5 million or 1.3% from the third quarter revenues and a year-over-year increase of 1.9%. The decrease from Q3 was driven by lower foundry and logic revenues, partially offset by an increase in DRAM and flash revenues. Systems segment revenues were $41.2 million in Q4, a $2 million decrease from third quarter record revenues and essentially flat year-over-year. The decrease from the third quarter is mainly due to the sale of FRT, which closed on October 31. Systems segment revenues comprised 24.5% of total company revenues, slightly down from 25.2% in the third quarter. Within the probe card segment, Q4 foundry and logic revenues were $83.6 million, a 13.3% decrease from the third quarter revenues. Foundry and Logic revenues decreased to 49.8% of total company revenues compared to 56.2% in the third quarter. DRAM revenues were $35.9 million in Q4, $8.5 million or 31% higher than in the third quarter, an increase to 21.4% of total quarterly revenues as compared to 16% in the third quarter. Flash revenues of $7.3 million in Q4 were $2.8 million higher than in the third quarter and over 4.3% of total revenues in Q4 as compared to 2.6% in Q3. Gross margin for the fourth - sorry, GAAP gross margin for the fourth quarter was 40.4%, same as in Q3. Cost of revenues included $2.8 million of GAAP to non-GAAP reconciling items, which we outlined in our press release issued today and in the reconciliation table available in the Investor Relations section of our website. On a non-GAAP basis, gross margin for the fourth quarter was 42.1%, 0.3 percentage points higher than the 41.8% non-GAAP gross margin in Q3 and 1.1 percentage points above the midpoint of our outlook range. The increase as compared to Q3 and the upside versus the midpoint of our outlook range were mostly a result of higher gross margin in the probe card segment, partially offset by lower system segment gross margin. Our probe card segment gross margin was 39.6% in the fourth quarter, an increase of 1.1 percentage points compared to 38.5% in Q3. The increase from Q3 is mainly due to improved factory utilization and lower excess and obsolete inventory expense, partially offset by a less favorable mix and lower volume. Our Q4 systems segment gross margin was 49.6%, 220 basis points lower than the 51.8% gross margin in the third quarter. The decrease relates mainly to the sale of FRT during the quarter, which resulted in a less favorable mix and inventory adjustments related to the transaction close. Our GAAP operating expenses were $59.6 million for the fourth quarter as compared to $66.6 million in the third quarter. The main reason for the decrease versus Q3 were nonrecurring M&A expenses in the third quarter and only one month of FRT OpEx in the fourth quarter, partially offset by higher performance-based compensation in Q4. Non-GAAP operating expenses for the fourth quarter were $51.6 million or 30.7% of revenues as compared with $54.5 million or 31.8% of revenues in Q3. The decrease relates to similar reasons I mentioned regarding GAAP operating expenses. Company non-cash expenses for the fourth quarter included $9.3 million for stock-based compensation, $1.6 million lower than in the third quarter due to timing of grants. $0.8 million for the amortization of acquisition-related intangibles, $0.5 million lower than in Q3 and depreciation of $7.7 million, similar to the third quarter. GAAP operating income was $81.3 million for Q4 and includes a $73 million gain from the sale of FRT compared with GAAP operating income of $2.7 million in Q3. The gain from the sale of FRT has been excluded from our fourth quarter non-GAAP results. Non-GAAP operating income for the fourth quarter was $19.1 million compared with $17.3 million in the third quarter, an increase of $1.9 million or 10.8%. GAAP net income for the fourth quarter was $75.8 million or $0.97 per fully diluted share compared with a GAAP net income of $4.4 million or $0.06 per fully diluted share in the previous quarter. The main reason for the increase is the gain on the sale of FRT. The non-GAAP effective tax rate for the fourth quarter was 21.2% as compared with 12.2% in the third quarter, mainly due to usual year-end adjustments and changes in mix of foreign versus domestic taxable income. For the full fiscal 2023, the non-GAAP effective tax rate was 15.6%, within the range of 13% to 17% previously communicated and similar to the 15.4% in 2022. We estimate that our annual non-GAAP effective tax rate for 2024 will be between 14% and 18%. Fourth quarter non-GAAP net income was $15.7 million or $0.20 per fully diluted share compared to $17.3 million or $0.22 per fully diluted share in Q3. Moving to the balance sheet and cash flows. We used $0.3 million in free cash flow in the fourth quarter compared to generating $16.9 million in Q3. The main reasons for the change were timing of shipments to and collections from customers during the fourth quarter and higher capital expenditures. We invested $9.9 million in capital expenditures during the fourth quarter compared to $5.9 million in Q3. This brings our 2023 annual capital expenditures to $56 million, within the range previously communicated. The decrease in CapEx in the second half of 2023 as compared to the first half and as compared with the $65.3 million invested in 2022 is due to completing the majority of the long lead time facilities and equipment investments required to reach our target financial model. Accordingly, we expect CapEx in 2024 to be between $35 million and $45 million. At quarter end, total cash and investments were $332 million, an increase of $84 million from Q3. The increase was mainly a result of approximately $104 million received from the sale of FRT, partially offset by the $9.9 million of capital expenditure, as I just described and by stock buyback in the amount of $20 million. As of the end of the fourth quarter, we had one term loan remaining with a balance totaling $14 million. Regarding the stock buyback, as I mentioned, during the fourth quarter, we purchased $20 million worth of shares to fully utilize our $75 million 2-year buyback program that was approved in May 2022 and started utilizing the new $75 million 2-year plan that was approved in October 2023. As of Q4 quarter end, $73.8 million remain available for future repurchases under this plan. As a reminder, the main purpose of the share repurchase program is to offset dilution from stock-based compensation. Turning to the first quarter non-GAAP outlook. We expect Q1 revenues of $165 million, plus or minus $5 million. At the midpoint of our outlook range, Q1 revenues are expected to be approximately $3 million lower than in Q4. The expected decrease relates to lower systems segment revenues, mainly due to the sale of FRT in Q4. And in the probe card segment, we expect flat Foundry and Logic and lower Flash revenues in the first quarter, partially offset by the increase in DRAM revenues. The sale of our Chinese subsidiaries that we announced today is expected to close in the first half of 2024, and it is not expected to have a significant impact on our financial results. First quarter non-GAAP gross margin is expected to be 41%, plus or minus 150 basis points. The expected decrease at the midpoint of this range as compared to Q4 '23 gross margin is a result of a less favorable product mix, mainly the expected decrease in Systems segment revenues and the increase in DRAM revenues. Although we expect HBM revenues to grow in the first quarter, non-HBM DRAM revenues, which have a lower gross margin profile, are also expected to grow. At the midpoint of these outlook ranges, we expect Q1 operating expenses to be $53 million, plus or minus $1 million. The increase as compared to Q4 is mainly as a result of the annual benefits reset. Non-GAAP earnings per fully diluted share for Q1 is expected to be $0.19 plus or minus $0.04. A reconciliation of our GAAP to non-GAAP Q1 outlook is available on the Investor Relations section of our website and in our press release issued today. With that, let's open the call for questions.

Our first question comes from Brian Chin from Stifel. Please go ahead with your question.

Hi, there. Good afternoon. Thanks for letting us ask a few questions. Maybe first, and I know Shai, you just said that - I think you said that upon closure in the first half with the China divestiture kind of has no impact. But I imagine there are some financial implications either in terms of cost and margins, some expectations as it relates to revenue, even maybe some cash on the balance sheet. Can you maybe break that down a little bit more? And also whatever regulatory hurdles or other hurdles need to be cleared to consummate the transaction?

Sure. So as I said, we don't expect it to have a significant impact on our financial results. When it comes to the balance sheet, once the deal closes, we will make the appropriate disclosure with more details. But since the details of the transaction were not disclosed, you can imagine that we concluded it's immaterial. When it comes to the P&L, again, not a material impact since we continue to maintain the direct relationship with the multinational customers in the region. And with respect to the local China customers, we have the new distribution agreement. And we expect and hope that this will continue to grow our China business as we move forward. And that's the conclusion we don't expect it to have a material impact. And Mike, do you want to refer to the regulatory...

Yes. Brian, this has been structured in a way where we don't believe there are significant regulatory approvals required. Basically, what we're doing is divesting what's in China already. And so there's no technology transfer, no significant technology licensing. It really is a focus and a shift to our operational and customer channel strategy in the region, given some of the challenges we've had with the export control. You've seen our domestic China revenue contract over the past several quarters, and this is a response to that. We are hopeful that Grand Junction can bring some more resources and focus to those businesses and through the distribution channel, help grow our domestic China business for us.

Okay. That's helpful. And for maybe for my follow-up, can you quantify - I guess it's been operating maybe around $10 million a quarter, but what the HBM contribution was to the $36 million DRAM in Q4? And then also kind of more broadly, do you see wafer probe card test intensity continuing to increase alongside your customers' road maps based on more die stack and hybrid bonding, et cetera? Or do you see test intensity leveling off at some point as customers yield and manufacturing efficiency improves?

Yes, I think it's a question of timing on the second one. I think for the medium term, certainly through 2024 and into 2025 with HBM, customers are still riding up a pretty significant yield learning curve. And so the increase in test intensity that we've talked about associated with die-stacking and advanced packaging of 20% to 30% I think we're pretty confident is going to hold here as we go through the early part of the HBM3 and into the HBM4 ramp. Over time, as with anything, we see this in new nodes as well. Customers accomplished the yield learning using products like ours, reducing the overall test intensity, improving their yields. And so we would expect it to go down over time. But I think we're pretty confident in increased test intensity as all the different yield reduction modes associated with die stacking work through in HBM and in the logic space as well. On the numbers, HBM in the fourth quarter was approximately $10 million, as you said, maybe a little bit more of the $36 million of DRAM revenue. And as we said in the prepared remarks, we expect that to increase around 50% sequentially, so up into the mid-teens in the Q1 outlook.

Okay, great. Thank you.

Thank you. One moment for our next question. And our next question comes from the line of David Duley from Steelhead. Your question, please.

Yes, you're right. Thanks. I noticed the Foundry & Logic revenue was down, it's similar decline that we saw in the revenue out of the geographic region of Taiwan. I was just wondering if you could make some a lot more elaborate comments about that? That's my first question. And my second question is, could you remind us what percentage of the overall DRAM market uses MEMS-based probe cards? And I think you mentioned that all the high-bandwidth memory stuff is going to be on MEMS...

Yes. The DRAM wafer probe market is almost entirely MEMS-based. Us and our primary Japanese competitor in high-end DRAM, really the only way to build these probe cards, which test the entire wafer once and have approximately 100,000, 150,000 individual contacts on them. The only way to do that in a cost-effective and high-quality way and deliver the speed performance, the high power performance is with the MEMS technology. And so I don't view HBM in and of itself as a headwind or a tailwind for MEMS adoption considering we're already largely adopted with MEMS and DRAM. But the requirements, as we talked about in the prepared remarks are more stringent. And so it increases one, the value to our customers. It also increases our competitive differentiation on things like speed, high-speed performance and thermal scaling. And so it's not purely a MEMS adoption story, but really a raising of the bar of the existing MEMS probe card for HBM, which as Shai commented helps our gross margins in the segment a little bit. On the Foundry & Logic observation, if you recall back on our previous call, we had a very strong third quarter with some of our major Foundry & Logic customers. And in particular, in the foundry space, delivered high volumes of two high-performance probe cards for high-performance compute projects. And those are in the digestion mode right now. So the inference you've drawn is correct. It also ties to the expectations we said on the previous call about some digestion in the foundry space as we go through Q4 and now Q1.

And just as my follow-on, you talked about in your prepared comments, I think some place about you saw unusually strong demand in just in DDR5. Is that associated with the specific end market? Or could you just maybe just elaborate further on that particular comment? Thank you.

Sure. The overall DRAM guidance, as we said, our outlook is that we're going to approach the levels that we approached in the middle part of 2021. So somewhere in the low $40 million of quarterly DRAM revenue. And that's composed. You can do the math from the previous question-and-answer session. You can do the math on how much of that is HBM, which leaves you with some pretty solid growth associated with non-HBM memory. We're seeing DDR5 for both mobile and server PC applications be pretty strong in the first quarter. I want to be clear that we're not calling a DRAM upturn at this point. It's pretty concentrated on a couple of designs and mostly at one customer, but it is an interesting indication of our customers beginning to invest in new designs because we know DRAM is cyclical, and we know it's going to turn at some point. So this represents some investments in them getting ready for the ramp when it does turn.

Thank you.

Thank you. And our next question comes from Krish Sankar from TD Cowen. Your question, please.

Yeah, hi. Thanks for taking my question. I have two of them. First one, if I look at your guidance, I'm just kind of curious, Mike or Shai, you said foundry logic revenue is flat, HBM growth, 50% and overall DRAM revenue is approaching peak levels in Q2 of '21, which is $42 million, and DDR5 is growing too. But if we do the math, it looks like HBM as a percentage of DRAM revenue is going to be higher in March versus in the December quarter. So why is gross margin still lower? Shouldn't gross margin be better than December then?

Well, let's not forget the system segment, right? We did - I did talk about the call that Systems segment is expected to go down in Q4. And as you recall, our system segment gross margin historically is higher. So we're going to have less favorable mix between systems and probes, and that's another driver that pushes gross margin a little lower than Q4.

Got it. Got it. And then I just had two other quick questions. Mike, if we look at your HBM share, you clearly have done a great job in HBM3 and 3E versus HBM1 and 2. I'm just kind of curious, do you expect the momentum to continue next year or so when we get into HBM4 and beyond?

Yes. Krish, I think we see the same progression of test complexity, there really shifts competitive advantage towards us as we move from HBM3 to 4. I think one of the obvious ones is, it's a higher - more die being stacked. And that clearly, as we look at customers' test strategies, as I said in the prepared remarks, they're not just probing each individual component die, but they're probing the stack as they build it up. And so higher stacks probably mean less yield, but also probably mean higher test complexity, higher test intensity as we move to HBM4. In addition, obviously, the clock speeds go up, the densities go up. And so those are all good trends. And I think it's one of the things where we're spending a good fraction of our R&D budget on making sure we can continue to drive that capability road map forward and serve the increased complexity of HBM4 and derive some competitive advantage from it. If I go back to your initial comment that Shai answered, actually, the mix between regular DRAM and HBM DRAM in the low 40s is nominally the same as it was in Q4. So that's one of the reasons why you're not seeing a margin uplift associated with DRAM.

Got it. Got it. And then a quick clarification. I think Brian asked this on the China ops divestment. To the multinationals in China, is this still going to go through the Grand Junction semi? Or is it going to be directly from Form?

Yes. No. Because the multinationals that operate in the region are global customers for FormFactor, they are not part of this distribution agreement. FormFactor will continue to support those customers in a global way and where we need local resources, we'll contract those things out. But you can think of the multinationals, which historically have been the vast majority of our China revenue continue to be managed by FormFactor and are not part of the distribution arrangement.

Got it. Thank you very much, Mike. Thank you.

Thanks, Krish.

Thank you. One moment for our next question. And our next question comes from the line of Tom Diffely from D.A. Davidson. Your question, please.

Yeah, thank you. And good afternoon. I guess, first of all, when you look at the memory segment, you talked about some next-generation DRAM chips, are you seeing anything on the flash side, any next-generation flash chips that require new designs?

Tom, as I think you know, our flash market share and consequently, our flash revenue is pretty minimal compared to DRAM. It's a market where the requirements are not that challenging from a speed or density perspective, which is really where we derive competitive advantage and why we're strong in DRAM. Flash, because of die sizes, because of test feeds, because of things like built-in self-test to the chips, really hard to drive a competitive advantage. So we do have some share there. But as you can tell from our historical financial results, it's not significant. We do see some new designs, but given my statement about our market share, we don't have the broad view of the flash market that would allow us to make the same kind of observations we can in DRAM. Having said that, I think the general view, when we talk to customers and other suppliers is that flash is probably going to trail DRAM in terms of recovery as inventories are still high and pricing is not where it should be to drive an upturn. But we are continuing to be opportunistic in the flash market and where we can differentiate with speed and/or capability. We're taking advantage of that.

Okay. And would you expect your flash share to go up over time, given the acquisition you made a couple of years ago of some technology there? Or is it kind of in this segment or in this range for a bit?

Yes. I think it's in this range for a bit. So the acquisition you're talking about, we acquired Advantest's probe card businesses a few years ago or business a few years ago. And if you remember, we primarily did that, although it is a flash test platform, a flash probe card platform. We primarily did it because it feeds elements of our DRAM road map that we're now in the final qualification stages with a key customer. That will help us from an overall market share perspective, at least at that customer. So we, again, acquired it more for the DRAM capability, although being engaged in flash does help you work out the bugs at a lower complexity level.

Great. Thanks. And as a follow-up, Shai Shahar, when you look at the target model going from where we were in 2023 to the target model, like 700 basis points of margin improvement. Is most of that just coming from overhead absorption? Are there some cost reduction programs that need to take place?

I would say three things. One is volume. Yes, as you pointed out, we have been adding capacity, so we need volume to go up to fully utilize this capacity and improve absorption and utilization. The second element is mix. We expect the growth from where we are today to our target model to come mostly from Foundry & Logic, which is an area that has a higher gross margin. And the third component is the cost reductions. We have a few initiatives across the company, some task forces to improve gross margin, focusing on costs, things like automation and vertical integration, more efficient production. And these things also expect to contribute on our way to reach the target model of 47%.

Okay. But would you say that over the absorption is the biggest factor?

I would say it's distributed kind of equally between the three components.

Okay. That's helpful. Appreciate your time today. Thank you.

Thanks, Tom.

Thank you, one moment for our next question. And our next question comes from the line of Christian Schwab from Craig-Hallum Capital. Your question, please.

Great. Mike, on the DRAM business and the 50% sequential revenue growth, is that driven by your current lead customer? Or is that expansion starting to ramp with the second customer?

Yes. When you break down the increase, it really is driven by our lead HBM customer, who also leads the overall HBM marketing share. So that's the primary driver. I did - it's probably a subtlety, but I did in the prepared remarks say that we expect revenue from all three major DRAM manufacturers in HBM. So there's engagements for those. But when we think about the Q1 step-up, it's very much driven by our lead customer. It's a key 2024 strategic objective for us to make sure that we capitalize on HBM growth at all major DRAM manufacturers. And I think we're making some pretty good progress with that.

Once you have all three, how big could the high bandwidth memory portion of the business be?

Yes. Yes, it's a good question. And I - so I think we'll stick with the idea that our HBM revenue in 2024 on a quarterly basis could double from the quarterly run rate that we had in 2023. And the reason for that is it's a little difficult right now to sort out how much double counting is going on in terms of forecasting between the different suppliers of HBM, DRAM are customers. I think if you back out the forecast, the growth and add them all together, the growth assumptions are probably there's some double counting in there. So I think our - the expectation that we communicated on the last call and through some of the investor conferences as we've gone through the back part of the year and to start 2024 of the HBM run rate doubling on a quarterly basis from where it was in 2023, the right expectation. And then you can see in Q1, we've made some good steps towards that.

Okay. That's great. On the Foundry & Logic business, the leading manufacturers of chips, whether it's Intel or AMD or TSM are kind of pretty optimistic regarding aggregate unit growth and the huge volume markets of PCs and smartphones, they're just not all that enthusiastic about it in March. But they are as we go throughout the course of the year. And given some of the new design ramps and new chips coming to market throughout the course of the year. I mean is it logical that that business exits the year at $100-plus million run rate again?

Yes. I think you've identified the key drivers for it. Certainly, in the first part of the year, whether you look at our Q1 guidance, kind of extrapolate what some of those customers in the high unit volume markets like PCs and handsets are conveying. There's some optimism associated with the second half. Given our visibility, right, remember that probe cards have lead times well within a quarter, much less than a quarter. And so our direct visibility doesn't extend anywhere close to that. But I think the combination of inventories being at much healthier levels and probably now a balance between output at these key customers and the actual sell-through that's now been resolved. So that puts things in a better place. And I think if there's some end demand pickup in these large unit volume markets like PCs and handsets in the second half, we should see some growth there. But it's beyond our visibility beyond the head labs. What I would say to close that topic is when I compare things to a year ago and people were optimistic about a second half recovery in 2023, I feel like the industry is in much better shape from an inventory and production and capacity standpoint a year later here in the first part of 2024.

Great. And then I'll just slip in one more question, if I can. You've been working on a qualification with a potential large customer for some time, I think a few quarters anyway, I guess. Is there any update on where we sit with that? And do you feel better about that? Do you feel better about potential timing of that? Any update would be great?

Yes. We don't have a huge update for you, but we have talked about this in the past. Obviously, the large fabless microprocessor and GPU customer is a place where we do not have significant share. And given our strategy of diversification, different customers, different markets, that's an important place for us to qualify and hold a significant share position, especially given their leadership in some of the end markets. We have made some - as you know, we've been at this for a while. We have made some changes in how we're resourcing that. The good news is the customer has a clear 2-supplier strategy, and there's really only 2 suppliers that can do this and FormFactor's one of them. So it's really up to us to improve our execution and get there. I'm confident that we can qualify at least in 2024. That will take a while to build into a significant share and revenue position, but we're setting the groundwork now, and it's a very important objective for some key people of FormFactor in 2024.

Great. No other questions. Thank you.

Thanks, Christian.

Thank you. One moment for our next question. And our next question comes from the line of Craig Ellis from B. Riley Securities. Your question, please.

Yeah. Thanks for taking the question. So Mike, hard to believe there could be even more DRAM questions, but there were some new ones I wanted to better understand. As we look at high-bandwidth memory here in the first quarter, understandable that it's ramping given what's going on more broadly. But the question is this, as you look at the mix of your high band with memory exposure in 1Q from high-bandwidth memory 3 to potentially 3E, which I think really launches commercially on a system in 2Q and high bandwidth memory 4, which I think everybody expects to come out in early 2025, how much of the mix in 1Q is 3 versus 3E and 4? And to the extent we're not really generating revenue on the latter 2? When would you expect that to hit?

Yes. There actually is a little bit of revenue on 3E. So most of the production volume, as you note, is on third generation or HBM3. But 3E, the mini step, we are shipping probe cards in some significant volume. I don't have the mix off the top of my head, but I guess it's something like two thirds HBM3, one third HBM3 and then a sprinkling of HBM4 in early R&D shipments.

Yes. There are discussions about a potential format change in PCs from indiscernible to LP cams. I'm unsure if this would affect probe card intensity, but do you observe anything on the personal computer side that might increase probe card intensity related to AI?

I don't think so, Craig. I think those format changes, especially, that's two steps downstream from us in the integration when they get integrated into the package and then into the module. I don't anticipate that having - and we, of course, interact with the die at the wafer level. I don't anticipate that would have a significant impact. What we really need is a PC refresh cycle to drive unit volume increases of PCD.

Yes, I hear you on that one. And then for the second question, typically, I think in the first half of the year, the business within Foundry & Logic would start to benefit and have a signed way relative to an APU program at a large foundry? Is everything on track there? And do you still expect to hold the same share that you've historically had there?

Yes, I think so. I mean it's going to be an interesting year with in the foundry business, a lot more high-performance compute than just application processor, although I think the application processor projects in the foundry space generally continue to be big middle of the year drivers of revenue. Those are key customers and very important focus areas for us as we move through 2024. There are one element of the overall diversification strategy we talked about, right? The DRAMs running pretty hot right now. HBM, not so surprisingly, but DDR5 being, as I said in the prepared remarks, a bit surprising given where we are in the DRAM cycle. But it's exactly a case study of why we've put these different businesses together to try and produce a relatively stable top line demand profile so that we can weather this subcyclicality and continue to invest in things like R&D for competitive differentiation and capacity.

Got it. Thanks, Mike. Appreciate the help.

Thanks, Craig.

Thank you. One moment for our next question. And our next question comes from the line of David Silver from CL King & Associates.

Thank you for taking my question. I have a strategic inquiry about capital deployment at this time. Mike, with the sale of the Metrology business, you had to make a strategic choice not to invest in its growth. I also see that you have some additional capacity at Livermore. Considering your balance sheet, which is quite liquid, could you share your thoughts on the best use for the additional or excess cash? For instance, does it make sense to pursue vertical integration, either forward or backward? Are there areas in your global operations where you could expand profitably? Or is there something related to the equity investment your major competitor recently received that might necessitate a counteraction to maintain your competitive position? With your highly liquid balance sheet, what are your thoughts on optimizing a portion of that cash?

Yes. I'll let Shai talk through the details. But I think in an environment where we still expect consolidation in the space, we don't think holding on to some cash, especially with decent returns is a bad strategic move. We're going to need dry powder for M&A. We continue to be believers in M&A and consolidation, not necessarily inside our served segments, but to expand our served available market and cash is a very useful asset to have. So with that, I'll turn it over to Shai to talk a little bit about capital allocation priorities.

Right. Yes. So as Mike mentioned, our priorities really didn't change compared to what we communicated before. We are focusing on reinvesting in R&D. We're still investing in capacity. Although we started down recently, things like vertical integration that you mentioned and automation. And we have the share repurchase program that I talked about. We still have $75 million to invest in share repurchase. This is to offset dilution. And it's a 2-year plan, and it's been one quarter since we announced it. So we still have 1 year and 3 quarters to do that. And M&A, right? And with the current interest rates and cost of capital, accumulating cash is aligned with our M&A strategy. If you look at our historical acquisitions, the MicroProbe acquisition in 2012, the Cascade Microtech acquisition back in 2016, we've been pretty good in creating value through our M&A activity and have been a good steward of capital.

Okay. That's great. I'll stop there. Thank you very much.

Thanks, David.

Thank you. One moment for our next question. And our next question is a follow-up from the line of David Duley from Steelhead. Your question, please.

Yes. I was just kind of curious, are you comfortable with unit volume - IC unit volume growth in the 6% to 8% range for 2024 for the foundry logic segments. And if that's the case, would - do you guys think you can grow faster than that or slower than that as far as the market growth?

Yes. I think as we look, there's a lot of variance in different assumptions for - specifically the second half of the year to drive growth. I think where we're more focused in our planning and forecasting and resourcing activities is on the first half because I think there's enough different variables where, sure, you could see 6% to 8% growth, you could see more, you could see less. And as I think most of you know, our visibility really doesn't extend into the second half. The if you were to have that scenario, I do think there is a very good likelihood that we can outgrow the unit growth of the market, especially if the bulk of it is associated with advanced nodes and some of the high-volume markets like PCs and mobile. And honestly, I don't see how you get to foundry and logic, high double-digit unit growth without PC and handset growth in the second half of the year. So in that scenario yes. I think it's reasonable given the adoption of advanced packaging given the increase of test intensity that we can outgrow the market, but I'm not sure I'd adopt that yet as a baseline scenario as we work our way through the first half.

Fair enough. One final question is I was just kind of curious from your point of view where you sit, you've talked a lot about increased intensity from advanced packaging, all sorts of form factors and whatnot. And I'm wondering - and that's generally been with Intel and TSMC, frankly. I'm wondering if you're seeing that start to spread out onto the OSATs because there's certainly a lot more chatter on their conference calls and I think ASE's CapEx is up more than 50% year-over-year this year focused on advanced packaging. And so I'm just wondering, are you starting to see a ramp up in kind of middle part of the market for advanced packaging? And are you well positioned to capture OSAT business?

Yes. So typically, the way the probe card market works is we have a very large installed base at the OSATs, but the OSATs often are not the purchasers of the probe cards. It's the fabless semiconductor manufacturers or the foundries themselves. And so there's a lot of interaction with the OSATs, but they're often not issuing purchase orders to us. So I think for us, advanced packaging, if it happens at the OSATs, if it happens at the foundries, if it happens at the IDMs, all a good trend because it's going to drive up test intensity. And if a fabless customer has adopted advanced packaging, and they're going to do it at the foundry or at the OSAT that's going to drive higher test intensity in either of those places no matter what. It's just a slightly different business model for us.

Okay, thanks.

Thank you.

Thank you. One moment for our next question. And our next question is a follow-up from the line of Krish Sankar from TD Cowen. Your question, please.

Thanks for taking the follow up. Mike, just a quick one. It looks like the high-density GPU customers are finally evaluating MEMS-based process. How to think about when that EVA will be done? When to expect post revenues from them? And if you can prognosticate what do you think the market share between you and Technoprobe would be in that specific category?

Yes. Yes. I think as the leading manufacturer adopts advanced packaging, that's really the discontinuity where they adopt MEMS probes. And it's an interesting case because of their large die sizes, they haven't really needed to adopt MEMS probes. But as they move to the Coos advanced packaging technology, MEMS probes are an absolute must. And so that's an opportunity, as you know, for us and our primary competitor in foundry and logic. Those qualifications are happening right now. I think the - and pilot production right now. I'd expect over time that to be an application in a customer where shares in this two supplier kind of window. We typically talk about it as a two thirds, one third. So most customers like to balance at 50-50, but there's often places where either us or our competitor have some degree of differentiation. And so it never quite works out to be 50-50. So I think you're going to start to see that in a significant way here in 2024. But of course, still the majority of silicon from that customer is not going to be on advanced packaging. That's a small but very lucrative part of their overall product portfolio. I still expect monolithic GPUs at least for 2024 to continue to stay on the legacy broke card technologies.

This does conclude the question-and-answer session of today's program. I'd like to hand the program back to Mike Slessor for any further remarks.

Thanks, everybody, for joining us today, and we'll talk to you again at some point in the spring, if not, at our next earnings call. Take care.

Thank you, ladies and gentlemen, for your participation in today's conference. This does conclude the program. You may now disconnect. Good day.
