Good morning and good evening, ladies and gentlemen. This is Justin Tham, and I will be moderating today's call. On behalf of ASMPT Limited, welcome to our First Quarter 2025 Investor Conference Call. Thank you for your interest and continued support. Please note that all participants will be in listen-only mode during the presentation by the management. We will start the Q&A session after the presentation. During the Q&A session, priority will be given to the covering analyst. Before we start, let me go through our disclaimer. Please note that there may be forward-looking statements about the company's business and finances during this call. Such forward-looking statements could involve known and unknown uncertainties and risks that could cause actual results, performance, and events to differ materially from those expressed or implied during this conference call.
For your reference, the investor relations presentation for our recent results is available on our website. On today's call, we have the Group Chief Executive Officer, Mr. Robin Ng, and the Group Chief Financial Officer, Ms. Katie Xu. Robin will cover the group's highlights, outlook, and next quarter's guidance, while Katie will provide details on the financial performance. Now, I will hand over to our Group Chief Executive Officer, Robin. Robin?
Thank you, Justin. Good morning and good evening to everyone today. It is a pleasure to have you all on our earnings conference call for the first quarter of 2025. Now, let's start with the key highlights of the first quarter. We achieved group revenue of $401.5 million, which met the midpoint of revenue guidance. The group's advanced packaging solutions continue to be a major beneficiary of AI adoption. AP solutions continue to deliver strong performance led by our thermal compression bonding, or TCB, tools. The group completed the delivery of the bulk TCB order to the leading memory maker, and these solutions are mainly used for HBM3E, 12-Hi, high-volume manufacturing. This quarter, the group expanded its TCB HBM customer base. We won initial orders from another global HBM customer, which has been followed by further orders in April 2025.
There were also continued bookings for chip-to-substrate tools serving the logic market, where our tool is a process of record. Lastly, within TCB, our chip-to-wafer TCB tools, enabled with active oxide removal fluxless capability, have progressed from qualification to pilot production at the leading foundry. This encouraging development demonstrates our technological advantage in fluxless tools. The strong progress made this quarter in TCB further solidifies our leadership in the market, and our focus for 2025 is on securing additional orders from both HBM and logic customers. Moving on to group gross margin, this quarter, we saw a rebound in group gross margin, which exceeded 40% and was driven mainly by better product mix in both segments. To finish this overview, the group's mainstream business continued to be affected by soft demand from automotive and industrial end markets.
While the growth trajectory of the mainstream business is difficult to forecast given the current environment, we are fully prepared to seize opportunities when the market recovers. With that, let me now pass the time over to Katie, who will talk about our group and segment performance. Katie.
Thank you, Robin. Good morning and good evening, everyone. This slide covers the group's key financial metrics for the first quarter of 2025. Group revenue met the midpoint of guidance, totaling $401.5 million. Group bookings delivered $431.2 million, which was better than expected, showing a 2.9% growth quarter-on-quarter and 4.8% growth year-on-year. The quarter-on-quarter increase was mainly due to higher SMT bookings, partially offset by lower SEMI bookings from a high base effect in Q4 2024. The year-on-year increase was driven by SEMI, which has shown year-on-year quarterly bookings growth over the past six quarters. In the first quarter, the group's gross margin was up 371 basis points quarter-on-quarter, but down 97 basis points year-on-year. The quarter-on-quarter improvement was due to both SEMI and SMT. Disciplined cost control measures and the seasonality reduced the group's operating expenditure by 11.3% quarter-on-quarter.
However, year-on-year operating expenses were up 4.1% due to the investments in strategic infrastructure and R&D to drive growth in our AP business. Thus, the adjusted net profit was HKD 83.2 million, up 1.6% quarter-on-quarter, but down 53.1% year-on-year. The year-on-year decline was due to a combination of previously mentioned slight reduction gross margin and OpEx increase for strategic investments, as well as Forex effects. For the first quarter of 2025, SEMI revenue grew to HKD 255.6 million, up 0.6% quarter-on-quarter and 44.7% year-on-year. SEMI contributed about 64% of the group's revenue. In Q1, SEMI registered revenue for the bulk order of TCB tools delivered to a leading HBM customer. SEMI bookings were HKD 222.9 million, down 19.5% quarter-on-quarter, but up 11.4% year-on-year. In Q1, there were new TCB bookings, which included initial orders from another global HBM customer, with further orders placed in April 2025.
There were also continued bookings for chip-to-substrate tools serving the logic market, where the tool is the process of record. In addition, there were mainstream wins for high-end smartphones and automotive applications. The quarter-on-quarter bookings drop was mainly due to a high base effect from the bulk TCB order in Q4 2024, while year-on-year increase was mainly due to TCB orders. SEMI's gross margin of 46.3% for Q1 2025 was up 368 basis points quarter-on-quarter, mainly driven by higher AP mix and a benefit from one-off items that impacted Q4 margin. Gross margin was up by 167 basis points year-on-year. In addition, as mentioned earlier, OpEx reduced quarter-on-quarter due to disciplined cost control measures and the seasonality. Lastly, SEMI 's profit was HKD 235.9 million in Q1 2025, an increase of 215.9% quarter-on-quarter. Moving on to the SMT business.
SMT delivered revenue of HKD 145.9 million in the first quarter of 2025, a decline of 20.3% quarter-on-quarter and 35.6% year-on-year, in line with ongoing softness in its overall market. SMT bookings of HKD 208.4 million were up strongly, 46.5% quarter-on-quarter, driven by strong seasonal system-in-package, or SIP, bookings. The automotive and industrial end markets appeared to have stabilized but remained soft. SMT's gross margin of 31.5% was up 180 basis points quarter-on-quarter, but down 827 basis points year-on-year. Quarter-on-quarter improvement was due to favorable product mix, while the year-on-year drop was mainly due to lower sales volume. Segment loss was HKD 5.3 million in Q1 2025 due to lower sales volume. I will now pass the time back to Robin.
Thank you, Katie. In Q2, the group expects revenue to be between $410 million-$470 million, up 3% year-on-year and 9.6% quarter-on-quarter at midpoint. We remain confident of sustaining AP revenue and expect the mainstream business to improve due to both seasonality and better-than-expected Q1 bookings. Looking ahead, the mainstream growth trajectory is difficult to forecast given uncertainties from the indirect impact of tariff. However, the group remains confident in the demand for advanced packaging and our TCB solutions for AI and high-performance computing applications. In addition, our global manufacturing footprint provides flexibility to navigate the potential impact of the tariffs. The group will continue to monitor the situation closely and adapt as needed. This concludes our first quarter 2025 presentation. Thank you, and we are now ready for Q&A. Let me pass the time back to Justin to facilitate. Justin.
Thank you, Robin. Let us now proceed with the Q&A session. For asking questions, please either use the raise hand function or type your questions in the chat to ASMPT Q&A. Please ask your questions one by one and limit them to two questions at each turn. Thank you. May I ask Donnie Teng of Nomura to unmute yourself?
Good morning. Can you hear me?
Yes.
Yes. Thank you. Hi, Robin and the management team. Thank you for taking my question. First question, as usual, housekeeping question. After some slight rebound in terms of the quarter-on-quarter booking momentum, would you be able to comment on booking direction in the second quarter? This time, I would specifically like to check the advanced packaging booking momentum in the second quarter and wondering if there is any preliminary impact from the CoWoS potential oversupply to drive some customers' start to hold the orders. Secondly, it's regarding to the SMT business. You know, because of this tariff drama, I think potentially some customers may want to seek some capacity expansion in different regions, for example, like Mexico or even in the future in the United States.
For SMT, I think that's an important equipment which could help customers to avoid sort of the uncertainty in terms of the tariff impact if they build the capacity in Mexico or US directly. Would you be able to comment on some of the dynamics you are seeing, particularly on SMT business after this tariff drama? Thank you.
Hi, Donnie. I see that you have two questions.
Only two.
Let me start with your first question is on the Q2 bookings. Maybe you start with Robin. That's the first question, right? The second question is also the AP booking, particularly on the preliminary impact on the CoWoS potential oversupply that was mentioned. Maybe I'll start with Robin on the bookings question first.
Thanks, Donnie, for your questions. Now, on the booking, as you know, we do not drive bookings, actually, but we always try to provide as much color as possible to you guys, right? I think for Q2 booking this time around, we remain confident that Q2 bookings will be within a similar range compared to the last few quarters. Of course, this assumes there is really no unexpected impact from the tariff landscape at this point in time. You talked a little bit about AP as well. Maybe at the same time, I can provide some additional color on how we see the Q2 bookings may pan out. For SEMI , AP momentum, we are confident that the AP momentum would be intact in Q2. In particular, TCB, we expect orders to continue to come in from both the memory and the logic side from a global customer base.
SEMI -mainstream, the way we look at it at this point in time is that it remains stable despite the macro environment. However, relatively speaking, compared to historical, it's still at a soft level for SEMI -mainstream. For SMT, as you can notice, we came back quite strongly in terms of booking on the back of a very low quarter in Q4 2024. Similar kind of picture with SEMI . In terms of mainstream, SMT is stabilized. In fact, in the recent time, we have seen opportunities in AI server and also the automotive market in China. I think these are some kind of color we can give to Q2 booking for both segments.
I think Donnie does have a follow-up question regarding he was focused on the tariff impact. The question is if the SMT side customers will see any capacity expansion. Maybe Robin, you want to have some commentary on?
Yeah. Maybe I comment in general first because, I mean, the tariff situation is at the top of everybody's mind during this recent period. In terms of direct impact, we do not see any significant or material direct impact on our operations. From the perspective of our overall business landscape, we are confident that AP will continue to grow, benefiting from AI adoption and also our superior technology leadership in this particular space. I talked about Q2 mainstream as well. The mainstream business is stable, but probably on the softer side for both SMT and SEMI as well. We are confident that the market is still growing. However, the indirect impact of the tariff makes the growth trajectory difficult for us. Now, coming from the customer side, we see both positive and negative effects on customer decision-making in light of the tariff environment.
While we haven't seen any order cancellations, some customers are, of course, evaluating, taking some time, say, evaluating their investment timing and location going forward. However, on the positive side, there appear to be two kinds of effects playing out. Let me go one by one. First, some customers show a willingness to engage in spot buys or delivery pull-ins to take advantage of the tariff pauses. You recall we have, I mean, the U.S. has imposed a tariff pause since April 9, for 90 days. Second, potential opportunities coming from incremental investments as customers diversify their manufacturing location to take advantage of the difference in tariff rates in various countries. I think that, Donnie, sort of answered your SMT tariff impact as well. Let me end by saying something on the tariff.
Our global manufacturing footprint provides flexibility, in our opinion, to navigate the potential impact of the tariff. We will continue to monitor the situation closely and adapt as needed. Having said all this, I think it's still unclear how the tariff situation will unfold and what the medium-term macroeconomic impact will be. I hope I answered your questions, Donnie.
Thank you, Robin. Just one quick follow-up is that you mentioned about the AP momentum may be still there into the second quarter. May I just simply ask whether it's mainly driven by memory, HBM, or logic? Thank you.
Donnie, I would say both. As I said, even for Q2, we are seeing orders coming from both memory as well as on the logic side.
Yeah. Yeah. I'm just wondering which one would be stronger. Yeah. Thank you.
Cool. I mean, trending-wise, I think lately with the HBM orders that we have won from the leading memory maker, and then in Q1 and Q2, we also won further orders from another memory maker. From the perspective, the HBM momentum, at least for ASMPT, is picking up nicely.
Understood. Understood. There has been keeping seeing those repeat orders, right, since fourth quarter last year?
Sorry, what's the question again, Donnie?
Yeah, I just want to make sure that you are still seeing repeat orders since fourth quarter last year from the first HBM customer. Is that?
No, we are working on it because the first order, as probably you understand, is a sizable order. It takes time for the customer to digest the capacity. Surely, surely we are working hard to continue to engage not just this memory maker, but the other big ones as well to garner more orders as we progress. On that note, I must add that we are doing well on the HBM side. We have proven ourselves that our tools in the first memory maker are already in high-volume production for HBM3E 12-HI. Also, we have been saying that for HBM4, we believe that we are the first to package the very complicated architecture for HBM4 chip. We have proven ourselves that we are able to do it.
In fact, the way we look at it is that the sooner HBM4 comes into full, it plays to advantage because HBM4 packaging is a step higher compared to requirements, is a step higher compared to HBM3E. That is where I think we could differentiate ourselves quite nicely from the rest of the pack because we believe our technology is able to handle the very complicated architecture of the HBM4 in terms of bonding accuracy, in terms of coplanarity control, in terms of die handling, ensuring no die crack, and so forth. We are confident that we will continue to win more orders in the HBM space.
Okay. Very clear. Thank you, Robin.
Thank you.
Okay. Danny, thank you, Donnie. May I ask Sunny to unmute herself?
Good morning. Could you hear me?
Yes. Yes, Sunny.
Thank you very much. My first question, I also want to follow up on TCB. You mentioned that you are getting orders from the second HBM customer. Could you help us understand the magnitude of the orders that you are getting in Q2? For your first HBM customer, since the customer should start ramping HBM4 soon, maybe in the second half of the year, based on your current engagement, would you expect to get the second bulk orders? That will be for fluxl ess TCBs, maybe into Q3 or Q4?
I think this question is for Robin.
Yes. For the second HBM customer, that's a question, Sunny. Yes. The orders are relatively smaller compared to the first one, but meaningful, I would say. We have received already two orders, one in Q1 and one in April 2025. Now, in terms of HBM4, as I mentioned earlier, we are confident of our capability in this space. We believe we have very good technology. We are definitely gunning for a market share for HBM4. I think the industry has probably recognized that ASMPT has successfully used our tools to package HBM4 already for a number of customers. I think that puts us in a good position to garner orders for HBM4. In terms of timing, we do believe that HBM4 should start some kind of ordering in the second half.
Now, whether it's in Q3, Q4, that's really not up to us. It's really up to our customer. We don't have a lot of visibility at this point in time, but it can happen in the second half of 2025. Depending on the type of HBM4, we believe fluxless for HBM4 may be needed for NCF application. Sorry. For NCF, we cannot use fluxless. The flux tool will still have to be used for NCF HBM. It depends on the customer. If they are going for NCF, it will not be fluxless. If they are going for MUF, chances are for HBM4, it has to move towards fluxless solution.
Thank you very much. A small follow-up on the technical details. Robin, would you mind sharing more thoughts on why NCF will not need fluxless TCBs?
Because of the inherent difference in the die between NCF structure and MUF. So NCF, you do not need fluxless, basically. Fluxless is good enough.
Got it. Thank you very much. My second question is on the leading-edge logic and so forth, chip -to- wafer, which I think most people are paying attention to. You mentioned leading-edge foundry has moved forward from qualifications to trial production for these tools. I guess the question is, has this customer decided if they will use chip -to- wafer to use fluxless TCB for chip -to- wafer anytime soon, or they are still taking some time? I wonder what are some of the key factors that hold them back from a faster migration to fluxless TCBs?
I think for the last bit of your question, Sunny, you probably have to ask them what is really, in a way, holding them back, what you have described. In any case, as far as we are concerned, I think we have made significant progress from qualification to now using our tool for pilot production. From our engagement with the leading foundry, we are in a good position. We are in a good position. We have proven our capability to be able to handle complex packaging requirement for chip -to- wafer application using our fluxless tool. We have recently shipped another tool to the leading foundry for the evaluation. I believe, as I said, we have made very good progress. We believe that we are in a good position to win the chip -to- wafer orders once the leading foundry makes up their mind.
Got it. Is there any timeline when this customer may be able to place some orders?
We hope second half of 2025, maybe. Yeah. Having said that, I think I've been repeatedly telling you that for chip -to- wafer, even if it happens this year, it's not going to be significant. Chip -to- wafer application, the demand, the high-volume demand will only come in 2026.
Got it. That's all I have. Thank you very much.
Okay. Thank you, Sunny. Now, may I ask Gokul to unmute yourself?
Yeah. Hi. Good morning. Thanks for taking the questions. First of all, on HBM, could you talk a little bit about your experience with this leading HBM customer? There's been quite a bit of competitive noise about this customer, that ASMPT tools have had some issues with this customer. Could you talk a little bit about where you are in terms of mass production for HBM3E, which is what I think your tools were targeted for? Secondly, I think when you talk about ASMPT being in the pole position for HBM4, is it mainly for this customer, given that you mentioned that fluxless will be required for MUF application for sure? Yeah, maybe start there.
Thanks, Gokul. Let me answer your question on the HBM. I sort of alluded earlier on the HBM question, how do we differentiate ourselves from a competitor? We differentiate ourselves by the quality of a bond in terms of accuracy, in terms of warpage control, in terms of coplanarity. Also, not to mention, I think customers value the scalability of our solution. We can move from a flux-based tool to a fluxless tool seamlessly, right, by adding a module, AR module, active oxide removal module on site. I think that's an important consideration also for our customer. Not forgetting, also in terms of HBM stacking, I think the ability to be able to stack chip as close as possible in terms of height, in terms of vertical stacking, what we call the chip gap is also important, right? You have to stay within a certain height level.
I think all this added up together put us in a good position in terms of technology vis-à-vis the other players in the space. Now, I think your second question is.
Maybe, Robin, Gokul wanted to touch on the progress of HBM4 progress with the leading customer or even customers in the HBM space. Maybe you can give them some updates.
Again, I think it all boils down to those advantages that I have elaborated quite a few times already this morning in terms of our HBM capability. I think that puts us, again, in a very good position to make progress, continue to make progress in the HBM space for 4. Because as I said earlier, HBM4, the AI architecture is challenging compared to HBM3. You need a certain capability to handle HBM4. Now, Gokul, I think you may also mention there have been some talk that our tools may be facing issues with the leading player. Let's put it that way. HBM stacking using TCB tools, sorry, I would say it's first of a kind, not just for ourselves, but also for the industry as a whole.
Now, typically in our equipment space, when we roll out first-of-a-kind tools, bound to have issues on site because there's a lot of process requirements needed to harden the tool. I would say this is part and parcel of rolling out first-of-a-kind tool for HBM stacking. It is nothing unusual. The fact that we have our tools have now been in high-volume production, using high-volume production for HBM3E 12-HI, and we have demonstrated our capability to do HBM4, I think that puts away whatever doubts the industry have of our capability for TCB stacking tools for HBM.
Got it. Just to follow up on that, Robin, what is your confidence on follow-on orders from this main customer? I think you had a pretty big bulk order that you've largely fulfilled in Q1. How is that follow-on order looking like? Maybe now that you have the second customer also, for HBM this year, who's going to be bigger? Is it going to be the second customer or the original lead customer in terms of revenue contribution?
Hard to forecast right now. We are deeply engaging all HBM players, including the third one. We have also successfully bonded. We have successfully bonded HBM stack also for the third memory maker. We are getting into deeper engagement with the third one as well in terms of joint development, kind of, yeah, arrangement with the third memory maker. Now, I think that sort of put us in a good position to garner more shares from the HBM space.
Okay. Just to clarify, we should expect follow-on orders from the lead customer pretty soon?
We are hoping for that for sure. We are working hard to get it happen.
Okay. Got it. My second question, I think last earnings call, I think you had outlined your HBM at a slow market growth. And you had also talked about 35-40% market share is your target for HBM. Given all the developments, especially on the HBM side you're seeing, what is the kind of rough market share you think you can secure, especially as we move to HBM4, which feels like where your tools seem to have an edge compared to competition? Do we get to that 35-40% market share for HBM4 or even higher? Any thoughts on that front?
Yeah. Gokul, definitely, we're working towards getting more market share constantly and relentlessly. Yeah, you're right. We came up with a term, and we did share. Our ambition is really to garner 35-40% market share.
For the TCB space.
for the TCB space.
It's not just for HBM. It's a TCB space overall.
In HBM, do you think it is going to be higher or lower than the 35-40?
Let's put it that way. I think there is definitely more competition in the HBM space compared to the logic space.
Gokul, just to clarify a little bit, I think when we put the $1 billion market share term out there last quarter by 2027, we had a little bit more color to it. I think the logic side, we actually started many years ago, right? We have a very strong foothold. HBM, really, we were basically the new player to the market. Robin's right, we aspired to get to the market share range. You have to bear in mind that we actually came into the scheme at zero market share, right? It is actually a really huge step up already.
Got it. Thanks. One small follow-up to Sunny's question on substrate. Previously, I think the understanding was that ASMPT was kind of behind your competitor in terms of qualification for this large foundry for chip and substrate. Do you think the position has changed now? You're largely on par with your competition, or it's still slightly behind competition?
Yeah. I think, Gokul, you're probably referring to chip -to- wafer rather than chip and substrate. For chip and substrate, we—yeah.
Chip -to- wafer. Yeah.
Correct. Yeah. Chip and substrate, we are still the sole supplier. Now, chip -to- wafer, yes, because we have really made significant progress from qualification to now using a tool for pilot production, I think we are well positioned in that space considering the progress that we have made.
Okay. Thank you.
Thank you.
Thank you, Gokul. Now, may I ask, Leping to unmute yourself?
Oh, I have two questions. The first question in your presentation, I think it's the page eight. I see an 8% improvement on the segment margin this quarter, although the revenue does not change too much. What are the major changes you did to improve the operating efficiency and how we should model the profitability of this SEMI Solution on the OpEx level in 2025? Thank you.
The label you're referring to, SEMI ?
Not SEMI , the Semiconductor Solutions segment, probably.
Yeah, SEMI S olution. You're talking about—I'm not sure.
The segment margin improved quite a lot this quarter, right?
Correct. Q1Q.
Yeah, Q1Q. Although the revenue does not change too much, right? Yeah, it's basically flat. What are the major changes and how should we model this OpEx level in the semiconductor solution?
Okay. I'm just trying to understand. You're talking about—sorry, sorry, I'm a little bit confused here. You're talking about gross margin or talking about OpEx?
Yeah. In other words, why did the segment margin improve so much in this quarter? Is it mainly due to the OpEx change, or is it mainly due to the margin expansion as well?
I got you. I'm sorry. Yes. Actually, the answer is both. If you look at the gross margin level, definitely, as we mentioned in the opening remarks, the product mix for the segment definitely was a very help. You guys were just spending some time talking about the TCB side of the momentum, that's for sure. Also, we mentioned that in Q4, there was a negative one-off margin hit, right? Q1Q, basically, the help too is a relatively lower comp. That's on gross margin side. Now, on the OpEx side, as we mentioned in the opening remarks as well, there's continued cost control measures in this relatively low environment. If you recall, we did announce restructuring programs in Q4, so we are benefiting from some of these savings from those measures.
At the same time, Q1, usually, if you look at our historical numbers, there is a seasonality that Q1 relatively is lower for OpEx. That is because the incentive share provision schedule only kicks in the last six days of the quarter, while all the other quarters we actually provide for the entire quarter, right? There is a seasonality to it. Net-net, that is what really supported the SEMI -profit improvement. I think you also have a question sort of looking out, right?
Right.
Yeah, we do not actually provide the outlook for the future profit and the margin. However, just like I always say, directionally, at the group level, right, you see that this quarter—I am talking about the group level now—at this quarter, we rebounded back to 40%. Also, as Robin mentioned, I think within the product mix, we do feel very confident with the momentum of AP. Therefore, we expect that the margin going forward, gross margin at group level going forward, will be in the range of 40%. I hope that helps with some of the color to the future profitability.
Yeah. Okay. Yeah, I'm very—so what will be the OpEx level you try to keep maintaining in terms of revenue scale? It seems your OpEx level is much higher than quite a lot of other SEMI -equipment companies.
Yeah. Let me kind of—on the OpEx, similar to what we communicate, we try to be quite consistent, actually. Every quarter, if you look at the OpEx level, it is probably HKD 1.1 billion-HKD 1.2 billion a quarter. At the beginning of the year, and very similar to last year, we did announce that with the growth opportunity we have, especially in AP, we have committed HKD 350 million of incremental investment, especially, again, for those R&D programs in TCB, in Hybrid Bonding, etc. We do expect the OpEx number to be relatively steady with some marginal increase against the very, very surgical, very specific programs that we are running, especially for the R&D side.
Okay. Okay. It's very clear. The second question is, I attended SEMICON China this March, and I listened to your quite impressive presentation by your representative about the advanced packaging. My question is, what's your view on the AP demand in China, and what are the major best-selling AP products in China? Yeah. Thank you.
I think a little bit, Robin. Yeah. I think we cannot comment too specifically, but in general, our advanced packaging solutions serve a global customer base. Yeah.
Okay. What will be the, let's say, percentage of your AP within your China business now?
Sorry, I think we don't break this down for competitive reason. Yeah.
Okay. Got it.
Thank you. All right. May I ask Kevin, Citi, to unmute yourself?
Hi. Thank you, Robin. Thank you, Katie, for taking my question. I would like to check on the mainstream side of our business. I think last time we talked, we mentioned that we're expecting somewhat of a bottoming out or a recovery in the second half of this year. Given the recent impact, especially from tariffs, do we still think that's the case? How much confidence do we still have compared to a couple of months ago? I think we saw that SMT bookings has shown quite a rebound in the past quarter. I think this is due to, in part, the SIP system seasonal recovery. How do you think this is going to trend towards the later part of this year?
Yeah. Kevin, thank you for your question. I did mention earlier, but I can sort of repeat again. Now, in the way we see mainstream business, in general, for both SMT and SMT, is that it has stabilized the mainstream business. Although it's still on the soft side because certain segments are still slow or sluggish, like, for example, the automotive and the industrial end market, especially in the European and the American region, they're still slow. Obviously, that also impacted, in particular, our SMT business. In general, the good sign is that the mainstream business has now stabilized. Looking at the—because of the tariff, we are confident that the mainstream business will continue to grow. The indirect impact of the tariff makes the growth trajectory difficult to forecast.
I can't give you a very definitive answer whether the growth will come in the second half or later because of the tariff situation.
Right. Oh, just a quick follow-up on the SMT part. Do you think the recovery in the first quarter is going to continue?
Looking at the color that I've given you earlier, we expect to be in the same range in the last couple of quarters. Yes, I think the short answer is yes. We will probably not fall to the level in Q4 for SMT Booking.
Right. Got it. Okay. My second question is, I would like to get some update on the hybrid bonding. I guess right now, the industry consensus is still that the industry might need hybrid bonding when we move to 12- HI. I guess the timing is probably around 2027, 2028, or possibly earlier. Just wondering how ready are we in terms of our second-generation tool? Do we have any following subsequent orders? This is coming in this year.
Yeah. Kevin, I believe it's probably you should be seeing 20- HI rather than 12. For 12- HI, definitely, we don't need hybrid bonding, right? So TCB. TCB is a choice of two. Our strong belief is that even for 16 -HI, okay, Our TCB is good enough for 16 -HI. Now, there has been a lot of talk about HB. Too early to tell. Of course, HB is maturing as we speak, but we still believe that HB, because of the total cost of ownership, is higher, as everyone is known by now. The industry will continue to use more cost-effective tools like TCB for both Logic and also HBM as far as possible. Yeah.
Okay. Got it. Thank you.
Thank you. I will have the last question from Gokul. Can you unmute yourself and ask your question?
Yeah. Hi. Thanks. First question. Given I think we've seen a pretty sharp share price decline, you're still sitting on pretty healthy cash balance. Just wanted to ask a question to Katie. Are we thinking about anything other than the regular cash dividend in terms of shareholder returns, any kind of share buyback policy, or anything like that that you've been thinking about with the board to kind of shore up the share price and help some of the investors? First question.
Hey, Gokul. Thanks for the question. Yeah, it was very interesting to write the company actually has some very solid cash performance in the recent years. However, due to the macro and the tariff uncertainties, we do not think this is the right time to launch a share buyback. We acknowledge our current share price level, and we're always evaluating different options to return capital to shareholders. We will continue to monitor the market situation, and we will look into buybacks when it's appropriate.
Got it. The second question I had, I think just following up on OpEx overall, I think if I look at the overall OpEx, I think last year was about HKD 5 billion. I think it used to be like HKD 4 billion or so in the last upcycle. The revenues obviously are much smaller than what they were. When you think about managing OpEx over the next maybe three, four years through the cycle, do you feel this is the OpEx level that the company should maintain, or is there a point at which you think we should think about some meaningful OpEx control measures or something like that, given the OpEx ratio is quite high? I think some of your competitors have actually managed this OpEx a little bit more flexibly over this last long down cycle that we have had.
Yeah. Gokul, thanks for the question on OpEx. As you probably recall, in this relatively long down cycle, we have conducted two or three restructuring programs already, and we'll continue to put cost measures on the various functions. We are mindful of the cost level that we have. Having said that, though, we do want to emphasize that as a technology company, we want to create the future of the company, which is really on the R&D programs for future products. That is why in the last two years, we actually proactively came out and announced the incremental investments. We will continue to do that. I think really it is a fine balance between the two, right? Investment for future and sensible cost control in this, again, relatively prolonged down cycle. We will continue to make sure that we strike a good balance between the two.
Got it. Maybe one small follow-up on the chip and substrate side. How do we think about visibility of orders? I think this year, obviously, is going to be a pretty strong year. Do we think that we should continue to grow next year for chip and substrate-related orders for this large foundry and some of the other OSAT players who are kind of having a similar supply chain?
We do. We do. Definitely. Not just in terms of the current architecture, but going forward, Gokul, you can expect the compound die or the compound die on the substrate will get bigger and bigger because of more capacity needed, more capability needed for the AI chip. That means customers will have continued to buy new tools in order to support the program to bond a larger die on the substrate. This trend will continue in time to come for sure. Yeah.
Got it. Thank you.
Okay. With this, this concludes our Q&A session. Let me request Robin to say a few words. Robin.
Thank you. Thank you for all your questions. Allow me to quickly highlight some key takeaways for our call today. The group delivered a solid performance and gross margin rebounded to above 40% in Q1 2025. We expanded our TCB customer base, won new orders, and our tools are being used in production for both logic and memory applications. This further solidified our leadership in the TCB market. While the growth trajectory of the mainstream business is difficult to forecast, given the current environment, we are fully prepared to seize opportunities when the market recovers.
The group remains confident in the demand for AP and its TCB solutions for AI and HPC applications. In addition, our global manufacturing footprint provides flexibility to navigate the potential impact of the tariff. As I said earlier, the group will continue to monitor the situation closely and adapt as needed. This concludes our call, and I'll see you in the next quarter. Thank you very much.
