For your reference, the investor relations presentation on our recent result 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 key highlights for the fourth quarter and full year 2025, and provide outlook and guidance for the following quarter. Katie will provide details on the financial performance for the year and quarter. Now, I will hand the time over to our Group Chief Executive Officer, Robin.
Thank you, Ben. Good morning, good afternoon, and good evening, everyone. Thank you for joining us today for our fourth quarter and full year 2025 earnings conference call. Before we begin, as I'm sure you know by now, I recently announced my decision to step down from my role as Group Chief Executive Officer for personal reasons and to devote more time to my family. I will remain in my role until a successor is appointed to ensure a smooth and orderly transition. I am proud of what we have achieved as a business during my time as CEO, and I'm grateful for your trust in me over the years. I'm confident that ASMPT has the right foundations and the people in place for its next phase of growth. Thank you once again for your continued support.
Moving on, the group has decided to divest ASMPT NEXX, which has been classified as a discontinued operation. Therefore, please note that unless otherwise specified on today's call, we will refer to the group's continuing operations only. For the key highlights for 2025. We experienced strong performance in both our SEMl and SMT businesses, supported by AI-driven structural growth. There was an increase in customer activity, translating into meaningful bookings and revenue for the group, evident in both Advanced Packaging and our Mainstream portfolio. Group bookings grew 21.7% year-on-year, driven by both SMT and SEMl businesses, and our full-year revenue increased 10% year-on-year, mainly from our flagship TCB solutions. Let's look at TCB. TCB momentum strengthened further in 2025 with significant new orders across Logic and Memory, solidifying our TCB technology leadership.
We established deeper engagement with both Logic and Memory customers and saw encouraging traction in areas such as HBM and C2W ultra-fine pitch applications. This continues to reinforce our position as a leading provider of Advanced Packaging solution as customers move to more complex chiplet-based and high-density architectures. Turning to our SMT segment, bookings were better than expected, supported by AI servers, China's EV ecosystem, and increased requirements for data transmission for base stations. Last but not least, we also advanced several transformation initiative from late 2025 to date. These are to enhance focus on our Back-End Packaging business, improve agility, and optimize our portfolio as part of a longer-term strategy. These actions will place us in a stronger position to scale capabilities in the areas where customer demand is most structurally aligned with our technology strengths.
Overall, 2025 was a year where we executed well, deepening customer engagements, and continued building the foundation for sustained growth. I will elaborate further as we move through today's presentation. Let me now provide an update on the TCB total addressable market. This time last year, when we presented this slide, we expected the TAM to reach around $1 billion by 2027. The landscape has evolved meaningfully. The acceleration of AI-driven investment, especially in advanced logic and High Bandwidth Memory, has expanded the market significantly more than our earlier assumptions. Based on our latest projections, we now estimate the TCB TAM to grow from roughly $759 million in 2025 to $1.6 billion by 2028, representing a CAGR of 30%.
This reflects sustained adoption of 2.5D architectures, higher HBM stacks, and the industry's move towards fine- pitch interconnects, all areas where TCB is increasingly the preferred solution. Our target market share remains at 35%-40%. This is supported by the breadth of our deep engagements across leading Logic and Memory customers and by the performance of our HBM C2S and C2W TCB platforms, including strong uptake of our plasma-enabled ultra-fine pitch capabilities. We are well positioned to benefit from this expanded TCB TAM, and we are committed to continue investing in this exciting technology. Moving on to Advanced Packaging. This remained a strong growth engine for us in 2025, supported by rising complexity in both Logic and M emory packaging.
As customers shift further towards chiplets, higher stack HBM, and fine- pitch interconnects, we continue to see solid demand across our TCB platforms in particular. Of note, with our breakthrough into competitive HBM market, we also grew TCB market share significantly, achieving record TCB revenue growth, about 146% year-on-year. In 2025, our AP revenue growth of 30.2% year-on-year was driven by TCB. As a result, AP's contribution to group revenue also increased from 26% in 2024 to 30% in 2025. Let's look at TCB more closely. In logic, our C2S solution maintains its dominant position as a Process of Record with a steady flow of orders from key OSAT customers in 2025. Extending into early 2026, we are pleased to share that we have secured additional orders for nine more TCB tools from the same customer.
We are well positioned for further order wins as the market shift towards larger compound dies. At the same time, our C2W ultra-fine pitch platform, enhanced with Plasma AOR technology, secured orders for two tools in February 2026 from a leading customer for C2W applications. Since the announcement, we have secured two more such tools, TCB tools, from the same customer. As the industry transitions from mass reflow technology to TCB, the group stands to benefit significantly as the preferred C2W solution provider offering plasma-enabled capabilities. This engagement underscore the confidence customer place in our ability to support tighter technical specifications and next-generation packaging roadmaps. In Memory, we deepened our engagement with several customers and continued to expand our share with shipments in Q4 2025. Our tools have demonstrated superior performance with industry-leading production yields and interconnect quality.
We were also the first to secure HBM 4 12-high orders from multiple players, and we are now leading HBM4 16-high development with our flux-based TCB tool deployed for sampling and our fluxless AOR TCB process under qualification. These are important milestones for our technology leadership as HBM architectures scale further. Beyond TCB, we also made progress in Hybrid Bonding, where we received customer buy-offs and shipped more tools. Our second-generation Hybrid Bonding solution is highly competitive, offering high alignment precision, bonding accuracy, footprint efficiency, and units per hour. In Photonics, revenue grew year-on-year, and we sustained our leading position in the 800G optical transceiver market while continuing development work with industry partners on 1.6T transceiver solutions. Our CPO collaboration also continued to move forward with key global players.
In SMT SiP applications, demand remained robust, especially in AI-related RF and system-in-package application. Our next-generation chip assembly tool also gained traction among advanced logic smartphone applications. Overall, Advanced Packaging delivered another year of meaningful progress with broader adoption across Logic, M emory, Photonics, and SiP, and it continues to be a central pillar of our long-term growth. Finally, our mainstream business. This accounted for about 70% of our fiscal year 25 group revenue. In 2025, AI-related demand was also a strong momentum driver for our mainstream business. Rising requirements for AI data center power management applications kept utilization rates elevated at leading global IDMs, benefiting SEMI mainstream. Meanwhile, SMT mainstream secured more orders to support increased data transmission requirements for base stations and AI server boards. In China, our mainstream business saw around 18% year-on-year revenue growth across both SEMI and SMT.
SEMI's growth was driven by strong demand for wire and die bond applications underpinned by robust OSATs utilization. SMT benefited from increased deployment of AI server boards and strong demand for EVs in 2025. With these highlights, let me now hand over the time to Katie, who will walk you through our group and segment financial performance.
Thank you, Robin. Good morning, good evening, everyone. Let me take you through the group financial performance. Before I start, I would like to reiterate that unless otherwise specified, the numbers I'll be referring to today are for the group's continuing operations only, with adjustments made under non-HKFRS measures. This slide covers our financial results for 2025. For the full year, the group delivered a revenue of $1.76 billion, representing an increase of 10.0% year-on-year, driven largely by TCB. Group bookings reached $1.86 billion, representing 21.7% year-on-year growth. Both SMT and SEMI registered high bookings during the year. The group continues to build a healthy backlog with book-to-bill of 1.05, which is our highest since 2021. In 2025, group adjusted gross margin was 38.3%.
This was 172 basis points lower year-on-year, reflecting lower gross margin in both SMT and SEMI. Group operating expenditures was HKD 4.56 billion, up 3.2% year-on-year, mainly driven by strategic R&D and IT infrastructure investments of HKD 237 million. As we communicated at the beginning of last year, these investments were partially offset by disciplined execution of cost control and efficiency measures. Looking ahead for 2026 for OpEx, as Robin mentioned, we're committed to continuing the investment in our core technologies, and we expect OpEx to rise by about HKD 200 million in 2026. In 2025, both adjusted operating profit and net profit improved year-on-year due to high revenue and operating leverage.
In the fourth quarter, we delivered a revenue for continuing operations and discontinued operations of $557.1 million that surpassed the upper end of our guidance. Q4 revenue for continuing operations was $508.9 million, representing an increase of 12.2% QoQ and 30.9% year-on-year, driven by strong growth across both SEMI and SMT. Group Q4 bookings were $499.7 million. The QoQ increase was due to stronger TCB bookings, while the year-on-year growth was largely driven by SMT's mainstream business. Group Q4 adjusted gross margin was 35.8%, down 175 basis points QoQ and 101 basis points year-on-year.
This sequential decline came from both SEMI and SMT, with year-on-year decline due to lower SEMI margins, partially offset by higher SMT margins. Group Q4 adjusted operating profit was HKD 161.0 million, up 4.3% year-on-year up 4.3% QoQ due to higher revenue and operating leverage. Group Q4 adjusted net profit was HKD 119.9 million, up 42.2% QoQ and 390.7% year-on-year. The QoQ increase was largely due to fees of HKD 39 million from order cancellations, while the year-on-year increase was due to stronger operating profit. Adjusted EPS were HKD 0.30. Moving on to the Semiconductor Solutions segment for the fourth quarter of 2025.
SEMl delivered Q4 revenue of $245.6 million, an increase of 9.4% QoQ and 19.5% year-over-year. QoQ and year-over-year growth were driven by AI-related applications, mainly from Photonics. SEMl Q4 bookings were $253.3 million, up 15.4% QoQ and 2.3% year-over-year. The increases were due to TCB orders from advanced logic customers and a market share gain in high-end die bonders. SEMl book-to-bill ratio in Q4 2025 was 1.03. Q4 adjusted margin for SEMl came in at 40.3%, down 102 basis points QoQ and 292 basis points year-over-year.
The QoQ decline was largely due to product mix and inventory provision as a result of an isolated order cancellation. Year-on-year decline was due to product mix, inventory provision mentioned above, and a higher factory utilization in Q4 2024 during the TCB ramp. Q4 adjusted segment profit was HKD 98.0 million, up 62.5% QoQ, and up significantly year-on-year. Both QoQ and year-on-year improvements were mainly driven by higher volume and fees related to the order cancellations. Let me move to the SMT Solutions segment performance for the fourth quarter of 2025.
SMT delivered strong Q4 revenue of $263.3 million, up 15.0% QoQ and 43.8% year-on-year, driven by AI servers, EVs in China, and the billing of a bulk order for smartphone applications. Contributions from automotive end market outside of China and industrial remained soft. SMT recorded Q4 bookings of $246.4 million, down 3.9% QoQ, up 73.3% year-on-year. The QoQ decline was due to seasonality, while the year-on-year increase came from the demand for AI servers and EVs in China.
Q4 SMT gross margin was 31.6%, down 225 basis points QoQ, up 199 basis points year-on-year. The QoQ decline reflected continued weakness in automotive and industrial end markets, and the billing of bulk order mentioned above, which had a lower margin. The year-on-year increase was mainly due to higher volume. Q4 segment profit was HKD 193.1 million, up 18.5% QoQ, and significantly year-on-year due to higher volume. This slide highlights ASMPT's revenue breakdown by end markets. Computer end market was significantly up, becoming the largest contributor to group revenue, accounting for 22%. The growth in computing was largely driven by our TCB solutions. Consumer end market was the second largest contributor at 17%.
Year-on-year revenue growth came largely from the group's mainstream solutions, consistent with higher revenue from China. The communication end-market contributed 16% to group revenue, driven by Photonics and high-end smartphone-related applications. The automotive end-market contributed almost 16% to group revenue, supported by EV demand in China, where the group remains the leading player. Lastly, the industrial end-market contributed 10% to group revenue, reflecting soft market conditions. As you can see from this slide, we are a truly global business, partnering with customers across all major regions. China remained the largest market, contributing 41% of group revenues. However, Europe and Americas declined year-on-year, mainly due to soft market conditions in SMT, with Europe's share of revenue down to 13% and Americas down to 11%.
Looking at Asia outside China, their proportion increased collectively from 24% to 34%, largely driven by TCB revenue. The group continued to maintain low customer concentration risk, with the top 5 customers representing approximately 16% of total revenue in 2025. We have an existing dividend policy of distributing about 50% of the annual profits as dividends. We firmly believe in returning excess cash to our shareholders. For the second half of 2025, with adjusted EPS at HKD 0.68 for continuing and discontinued operations, the board has recommended a final dividend of HKD 0.34 per share. In addition, the board has recommended a special cash dividend of HKD 0.79 per share after taking into consideration the net cash inflow from recent strategic projects.
Together with the interim dividend of HKD 0.26 per share paid in August 2025, the total dividend payment for 2025 will be HKD 1.39 per share. With that, let me now pass the time back to Robin for an update on our transformation initiatives and the next quarter's revenue guidance.
Thank you, Kitty. As mentioned earlier, we undertook several transformation initiatives from the late 2025 to date as part of our long-term strategy. In November 2025, we completed the divestment of our entire equity interest in AAMI in exchange for cash and new shares in Shenzhen Original Advanced Compounds Co., Ltd. In January this year, we announced a strategic options assessment of our SMT Solutions segment. The assessment is underway, we will update at the appropriate time when there are material developments. Lastly, today, we make public the decision to divest ASMPT NEXX, Inc. These initiatives share a common objective of optimizing ASMPT's portfolio, streamlining operations to enhance agility, and improving margin and profitability, while ensuring continued investment in infrastructure and technology development in high growth areas. They also sharpen our focus on the Back-End Packaging business.
In the meantime, business for all our segments continue as usual. Let me now turn to our Q1 2026 revenue guidance. The group expects Q1 2026 revenue to be in the range of $470 million-$530 million. At midpoint, this represents a decline of 1.8% QoQ and 29.5% year-on-year. Notably, the group's midpoint revenue guidance for continuing operations only already exceeds current market consensus, which includes both continuing and discontinuing operations. We anticipate sustained QoQ revenue growth in our SEMI segment, driven by TCB and high-end die bonders, although this will be partially offset by SMT seasonality. On year-on-year basis, the higher group revenue is expected to be driven mainly by strong momentum in SMT, coupled with steady growth of SEMI.
For Q1 2026, group gross margin is expected to improve, led by SEMl gross margin returning to the mid-forties level. This improvement is driven by higher volumes from TCB and high-end die bonders. SMT's gross margin, however, is expected to stay at similar levels as automotive and industrial end markets remain soft. The group bookings momentum will accelerate in Q1 2026, supported by both segments. Looking further ahead, structural industry growth from AI demand is expected to drive revenue growth across both SEMl and SMT. In TCB, with our industry-leading technologies and deep engagement across a broad AI customer base, we are well positioned to expand our TCB business in a rapidly growing market.
Our SEMI and SMT mainstream businesses continue to be supported by global investment in AI infrastructure and steady demand from China, while SMT, automotive and industrial end markets are expected to remain soft in the near term. This concludes our full year and fourth quarter 2025 presentation. Thank you. We are now ready for Q&A. Let me pass back the time to Ben to facilitate.
Thank you, Robin. Ladies and gentlemen, we will now begin the Q&A session. To ask a question, please click Raise Hand on Zoom, and I will request you to unmute. Please limit yourself to two question each time and pose your questions one at a time. With that, may I have the first question? Okay, Gokul, please unmute yourself and raise your question.
Yeah, hi.
Hi, Gokul. Yes, we can hear you.
Yeah. Hi. Hi. Good morning, hi, Ben, Robin and Katie. Robin, first of all, thanks for your leadership over the many years, and good luck on your retirement.
Thank you.
My first question is on TCB, the addressable market, TAM expansion to $1.6 billion. Could you talk a little bit more about where is this upside mostly coming from in your estimates? Let's say we get to this $1.6 billion, what will be the mix of HBM versus Logic look like in 2028? Given that you gave a estimate of $750 million addressable market for last year, what was the market share roughly for ASMPT last year? Should we assume that it was about 30% or so for TCB, just to get a starting point of your TCB journey, when we think about this TAM expansion? Thanks.
Hey, Goku, this is Katie. Let me try and address the questions, that you have. First, on the TCB TAM, let's just take a quick minute, on the methodology. Actually, last year, that was our first time publishing the, TAM at the billion. This year, actually, the methodology is very, very similar. We essentially used the, wafer per month, actually, you guys have published, in the
industry we start compared that to the number of AI chips and the interconnects and then the tools needed, right? It's the same methodology. To your question about what's driving the expansion, obviously, right, really is the starting point, is the wafers per month that has expanded significantly for the AI industry overall. That's the main expansion. In terms of the mix Hybrid Bonding, sorry, HBM and the Logic, I think previous years we've communicated the HBM is the larger portion of the TAM, and it will continue to be so probably until as we go into the outer years, right?
If we talk about HBM20 high beyond, then at that point, Hybrid Bonding will be kicking in, and then the Logic side, especially CoW, will actually become more prominent in the TAM. The other things you asked about the last year's market share, and you said about 30%, and you are quite in the ballpark for that one.
Got it. That's very clear. Thank you very much for that clarification. Second, on the proceeds from, I think this, rationalization of the portfolio and some strategic actions that you're taking, good to see that happen. Could you also talk a little bit about what is the kind of end state that you are hoping for once this rationalization is being done? Are there areas that you're kind of trying to bulk up on as it pertains to the Back-End Packaging business? Specifically on NEXX, what is the rationale for divesting NEXX given that has a fair bit of 2.5D bumping and ECD plating kind of business, which theoretically feels like closer to the Advanced Packaging business.
Just help us understand why that divestment of NEXX is also happening?
Right. Gokul, yeah, thanks for your question. I'll take that question, Gokul. Basically, I think it's really focusing, you know, really on our Back-End Packaging business because this is where, you know, we feel this is where the structural growth will be, and this is where I think our strength, you know, sort of match the industrial roadmap for packaging. Really back to, you know, focusing on Back-End Packaging. First you notice we divest our liquid business. That just is just one step. Now we are, you know, assessing SMT, which is more of the, you know, downstream operation. Then as to your question on NEXX, you're right. NEXX is, although it's Advanced Packaging, but it's not exactly back-end.
It's more, it's belonging more to the middle end. Their technology, to be honest, is more wet technology whereas back-end technology is really more on automation, on vision and so forth. We felt that it's probably a right time, you know, to consider divesting NEXX to really focus all our attention, all our resources on the back-end side. Yeah.
Understood. Maybe if I could squeeze in one more, I think. Any quick view on how the mainstream SEMl Solution business you're expecting it to progress, Robin? What are you hearing from your customers, given at least from a CapEx perspective, many of your customers seem to be moving up for the first time in this upcycle?
Yes. Yes. I think we're beginning to see maybe we talked about green shoots, some quarters back, but this time around the green shoots seems to be real, from a point of view. Now, because there is a tailwind behind the mainstream business, and this time around, we feel that, we have been talking for a few quarters already, Goku, that we feel this time around is underpinned by AI investment as well. You can imagine when, you know, industry, you know, continue to invest more and more in terms of data center. Besides GPUs, there are many other components inside a data, inside a server board, AI server board. You know, you have power measurement devices and many other components, right?
You can imagine with all these server boards going into a data center and the build-out of data center CapEx, there's huge, massive amount of components need to be packaged using both our SEMl wire bond and the normal die bond tools, as well as our SMT pick-and-place tools. This AI data center investments are really driving our mainstream, both on the SEMl side as well as on the SMT side.
Okay, that's very clear. We should expect that mainstream SEMls also should be growing. I think it's not been growing for maybe 3, 4 years now after 2021, looks like 2026 we should see some growth in the non-Advanced Packaging piece of SEMl Solutions as well, right?
Yeah. As far as we can see, I think our visibility is, again, is quite normal in our business to be limited to one or two quarters, right? I think, first half looks to be okay. Half-on-half, you know, better than half-on-half growth. Year-on-year, half year also we think it will grow. If you ask me on the second half, let's wait for a while to see how we develop, limited visibility at this point in time for second half.
Got it. Thank you very much. Thanks.
thank you, Goku, for your questions. I see a raised hand from Daisy. Yeah, I will request this Daisy to unmute and raise your question.
Thank you, Ben. Firstly, I want to ask about the HBF opportunities because I listened to your competitors' earnings call. They are talking about High Bandwidth Flash opportunities. Have you guys also seen these opportunities from ASMPT side?
Yes, we do, Daisy. Very good questions. I think this is again probably an exciting development. To be honest, we have not factored this into our TAM, TCB TAM, both because potentially the way we assess the technology or the packaging technology required, I think TCB could be also be a tool, you know, to package HBF. This is something that, you know, we look forward to. If the industry develop in this direction, I think we will also stand to benefit in time to come.
Okay. Thank you. Also following Gokul's previous question. You previously also mentioned that you expect the second half will also grow versus first half. I want to ask about the order visibility from ASMPT side, because I think in normal times, backend order visibility is 3-6 months. How is the order visibility now? What is the magnitude that you are seeing that second half could grow versus first half?
Correction, Daisy, correction.
Oh.
Maybe let me make it clearer. just now when I answered Goku's question, I'm just saying first half 2026, we have better visibility because of the momentum we are seeing in terms of Advanced Packaging as well as mainstream. Second half is still limited in terms of visibility. At least this time around, you know, we can see a little bit further, you know, maybe slightly more than a quarter. Second half, let me correct your statement, second half, we still have limited visibility. When I mentioned just now half on half, and I'm sort of giving you some color, first half this year, demand probably will be better than first half last year as well as second half of last year. I'm just comparing half on half and year-on-year.
But second-
Okay.
Second half, I repeat, we still have limited visibility at this point in time.
Okay. Understood. Thank you.
Yeah.
That's all my question.
Okay. Thank you, Daisy. Next, request Arthur to unmute.
Hi. Hi, Robin. Thanks. You'll be missed. Thanks, you and Katie and Ben. First, congrats on the strong results. First question is on the backlog. You highlight that the backlog almost over $800 million. Can you give us more color on the spread between the SEMl and SMT? Also, you highlight the high-end bonder. Can you share with us more on the non-TCB's product such as panel-level fan-out? Thank you.
On the backlog, just really quick, the SEMI side backlog is stronger, is a larger quantum than SMT.
Okay.
That will.
Is-
Oh, sorry.
Is it significant higher or it's a, you know, Is significant? Yeah.
Oh, you mean the percentages? Roughly 60/40, I guess. Don't quote me on exact. Somewhere there.
Okay, thank you.
Arthur, on your second question about high-end die bond, which I think you're referring to what we have mentioned in our announcement. Yes. I think, if you're referring to the same thing, I think it's good news. We have penetrated into a high-end die attach application for high-end smartphones, right? If you look at the camera modules of high-end smartphone, there are many odd-shaped components in there which need to be pick-and-placed as well. The customers have chosen our die attach application, you know, to place those components. This is a brand new market for us. We have never been in this market, so we really look forward to having more market share, increasing our market share in this particular area.
That's for the high-end die bond I think you're referring to. You also have a question on panel-level fan-out. We see a lot of trending in that direction. We feel that this is also driven by AI as well, right? Panel-level fan-out for components that go into data center becoming more and more visible. Definitely we have a tool, basically, a mass re flow tool that we can deploy, you know, for a solution like this. We're also pretty well placed to capture this opportunity.
Got you. Second question is on page 10. You highlight, there's an order cancellation on the SEMI side. Can you give us more color? Is it associated with NEXX?
Yeah. Arthur, this order cancellation does not have any association with NEXX. Let me just give a little bit more color on that. The order cancellation came from a global IDM, who's focused on automotive applications, and the order came a few years ago, and it was for our semi-mainstream products. The customer had to cancel the order due to weak automotive industry performance, that's why we got this cancellation. I want to make sure that you, we all understand this is a very much an isolated event.
Thank you. No, no more question.
Thanks, Arthur.
Thank you, Arthur. Next, I would like to request Liping to unmute and raise the question.
Okay. Thank you to take my question. The first question is also about the TCB TAM. When you derive the TCB TAM in 2028, what's the split between Memory and the Logic? You also say that you target the 35% to 40% market share in 2038. What's your current market share in Memory and Logic, and what's the upside we can expect in the next few years? Thank you.
Let me maybe just add a little bit more, basically, essentially the answer I've provided, Gokul, on the split of Memory and the Logic. Currently the Memory, the HBM portion in the TAM definitely is much larger than logic. As we go out few years out, this dynamic will actually shift, where the logic, especially, CoW will actually take a larger share.
Okay.
We cannot share the specific split for confidentiality reasons, or competitive reasons, I should say. In terms of market share, as Robin has mentioned in the opening, ASMPT is very, very strong in CoS. And also when we are actually making a lot of wins on CoW. Our market presence in the logic space is very strong. HBM, you guys remember a year ago we broke into HBM market, so we have gained market share there. That's kind of where we are in terms of market share.
Maybe just to add on a little bit in terms of the competition landscape. I think in the logic space, you know, we had a PUR, you know, for a very key supply chain, you know, for Chip-on-Substrate application. Recently the good news is that, you know, we announced we won, you know, two tools for CoW application, right, for the same supply chain, we won two more. I think it is a signal that, you know, we are also being recognized as a solid solution provider for the C2W space as well. On the Memory side, I think the competition landscape is different.
We have a strong incumbent in the Memory space. We have done a fantastic job. You know, in 2024 we have practically zero share in HBM, and then in 2025 we managed to penetrate in a very meaningful way in the HBM market. Now that we have a strong foothold in the Memory market, we look forward to better times ahead in terms of HBM demand allocation
The second question is about the Memory Super cycle. Are you seeing an acceleration of the capacity expansion from your HBM customer? Given your HBM4 12-high order win, are your now customer provide a longer term rolling forecast to secure your TCB tool for the 12-high and 16-high? How you play your capacity in this year for the TCB business? Thank you.
Yeah, thanks. Definitely, definitely in terms of HBM CapEx is really in line with, you know, investment in data center, right? When data center investment continue to increase, you can expect the HBM to continue to increase as well. Not just in the number HBM, but also in the higher stack, you know, from 12-high to 16-high to 20-high eventually. That means, you know, there'll be more and more opportunities for TCB packaging, you know, as HBM continue to stack up in terms of height. Now, you asked whether, you know, about capacity allocation. To be honest, I think there are some module differentiation between 12-high and 16-high, but they're not major.
Some hardware module need to be different if we use to package 12-high between 12-high and 16-high. There's some hardware modifications, but also some software. There's not much material differences between the 12-high TCB tool and the 16-high TCB tool.
Thank you. Thank you very much.
Yeah.
Thank you, Robin. Next I would like to request Simon Woo to unmute and raise question.
Yeah. Thank you very much. Yeah. Thank you, Robin, as always, and, we'll miss you. Thank you. The long term questions for 2028, you are expecting TCB market TAM $1.6 billion for 2028. Any rough idea the % of the Hybrid Bonding assumption for that time, or very low single digit, or mid single digit, or?
Sorry, Simon, because your line is breaking up. Do you mind to say it again?
Yeah, my question is the Hybrid Bonding portion of the 2028 TAM $1.6 billion?
This is a TCB TAM. There is no hybrid bond in the TCB TAM. I guess I'm you're asking our assumption the, of the hybrid bond adoption timing. Is that what your questions is?
Yeah. Sure, yeah. That's, that can help. Yeah.
Okay. In our model so far, for HBM 16-high, we assume that, we are actually confident that the TCB will continue to serve, 16-high. As we get into 20-high, it really depends on the JEDEC standard.
Right? If the standard continues to relax, then it will actually be an upside to this model. Otherwise, we assume in the model itself that the 20-high will be moving on to, hybrid bond.
Par-partially.
Partially. Yeah, partially.
Yeah.
Okay.
Yeah. The TCB can be used for the 20-high if the JEDEC has okay? Yeah. Yes, Simon. I think.
Yeah.
Looking at, you know, how the technology, TCB technology develop over the years and also into the future, we are confident that the TCB technology, together with, of course, we need to collaborate with our customers as well. You know, their wafer technology will probably, we believe, will continue to improve. I think a combination of both the wafer as well as TCB tools, we are hopeful and optimistic that 20-high can still use a TCB.
Of course, if, like what Katie say, if the JEDEC, you know, standard can be relaxed to increase the height from 775 to beyond 775, maybe 950 or even 1,050 micron, then the chance of using more TCB for 20-high and beyond will even be higher. Yeah. The situation is very dynamic. We just have to wait for a little longer to see how the industry play this out in terms of the high restriction.
Yeah, very clear, sure. Do you believe the logic area or fan-out PLP will require Hybrid Bonding as well, maybe, a few years later?
Simon, sorry, you're breaking up. Sorry, I need to ask you to repeat. You're breaking up.
I should use a better phone. You know, my question is logic area, do you see any meaningful progress for the Hybrid Bonding for COBs or some fan-out PLP area or?
I believe your question is in the logic area whether there's more opportunity for Hybrid Bonding, right?
Yeah. Correct. Correct. Yeah.
Yes. Yeah. Actually, to be honest, Hybrid Bonding has already been adopted at the chiplet level, right, for certain devices. For the certain device. We believe that that is already been ongoing. It all depends. Again, it's very, it's very dynamic, right? Even to be honest, even at the chiplet level, TCB can be used as a tool as well, especially when we look at the exciting technology that we're gonna develop for TCB going into the future. The TCB technology will get closer and closer to the Hybrid Bonding technology. So from that perspective.
Yeah.
From that perspective, we are optimistic and hopeful that at some point, you know, TCB can also be used also at the chiplet integration level. As I said,
Yeah.
This industry is very dynamic. Nobody knows what's going to happen.
Sure.
Let's continue to monitor this space.
Yeah. Very clear. Sorry, almost the last question, quick check. 30% your revenue is Advanced Packaging. That means anyway near half a billion dollars your revenue for Advanced Packaging last year. Any rough idea what was the TCB portion out of the total Advanced Packaging revenue last year?
You're talking about TCB proportion to the Advanced Packaging? Is that what you're saying?
Yeah. 2025.
Yeah.
Last year. Yeah.
Very dominant. A major share of the AP revenue for TCB, yeah.
Dominant means majority portion.
Yeah. Well, about, around there.
Yeah. Simon, if you look at the TCB market, the TEM slide that we shared and Robin mentioned, right? You know what the TCB market size was in 2025, and I think Gokul earlier mentioned about our market share. As you do the rough calculation, you actually will get there.
Mm.
If that's what you guys are trying to do.
Yeah.
Okay.
Yeah. $200 million, $300 million maybe.
Okay.
Sorry, one last question from some investors asking what's the overall the revenue disappearance or erosion after your massive restructuring for the SMT or leadframe, the backend area. Rough idea what percentage of the revenue will be off once you complete all the restructuring process? Thank you. Yeah.
Maybe, I'm trying to answer your question. For a clarification. For AAMI, we were 49% shareholding, and now after the disposal for AAMI, there's actually no revenue impact year-over-year or the last few years. There's no revenue impact at all. For the NEXX business we just announced today, to be as discontinued business, or put up for sale. NEXX revenue is about $100 million, if that's what you're looking for.
Yeah. All clear. Thank you very much. Thank you, Robin.
Thank you.
Thank you.
Thank you, Simon. Yeah. I think we have time for one final question. Donnie, we'll request you to unmute and raise your question.
Thank you for taking my question, and wish Robin you all the best after the retirement.
Thank you.
My first question is regarding to your guidance. Can you break down or elaborate more on the bookings momentum in the first quarter? Particularly TCB, because I think based on your announcement in fourth quarter last year, we already have received quite some TCB orders. I'm also wondering what kind of trend in terms of the TCB bookings into the first quarter this year. This is my first question. Thank you.
Thank you, Tony. I think you probably expect my answer. We cannot be too granular because for competitive reason as well. I think in overall, I think 2026, we were expecting TCB to continue to grow in line with the, you know, investment, so much investment in data center. Right. I think that's point 1. Now, if I drill down to the booking, I'll give you some booking color, you know, for Q1 2026. We likely to see a strong booking in Q1, QoQ, around 20% growth QoQ, and even stronger, around 40% year-on-year growth for Q1 booking 2026 for both SMT segment as well as, you know, the SEMl segment.
I think we have been talking a fair bit over the last couple of quarters as well that, you know, we see AP will continue to grow and because of mainstream momentum gaining, you know, very strongly over the last one or two quarters and into Q1 2026 as well. I think both, Advanced Packaging as well as mainstream will continue to do well in Q1 2026 as far as bookings are concerned. However, I have a caveat just now as well, right? With the stronger booking, also let me caveat or qualify that we might see some impact on revenue conversion, you know, because we are seeing longer material time due to tightness in the supply chain, right?
Although bookings are gonna be very strong in Q1, but the conversion to revenue may take a little bit longer than usual because of supply chain tightness. Okay? Yeah. I think this is some color I want to give you. I think Q1 bookings, the way we see it, will be the highest quarterly booking in four years.
Okay.
Yeah. Okay.
Understood. Can I have a follow-up on this? For the SEMI business bookings, the strong sequential growth, can we say it's primarily driven by conventional packaging or from Advanced Packaging?
I would say mainstream will probably grow a little bit more than Advanced Packaging. Advanced Packaging tend to be a bit lumpy. We have been saying that for a long time already. Don't expect AP revenue to be continuously high, you know? First of all, first and foremost, the customers are limited. Less customers than the mainstream. Second, these are high-value tools, so customers cannot continue to buy quarter-on-quarter. But the demand for TCB is steady for sure. Right?
Okay.
Don't expect this to continue to be on a quarter-over-quarter basis continue to grow.
Okay.
That's on the AP side. What we are seeing, you know, quite interesting is really on the mainstream side. We see really a pickup in terms of mainstream for those reasons I said earlier.
Yeah
... AI-driven data center.
Okay. Got it. My second question is regarding to your 2025 review in terms of the market share gain, particularly in the HBM market. If you, if I remember correctly, we actually received quite sizable orders from 4Q 2024 from leading HBM customers a nd since then into 2025, actually, the bookings, despite of, there are some repeat orders, but seems like not as significant as what we had back in fourth quarter 2024. Just want to clarify is that our market share gain in 2025 for HBM and TCB is primarily driven by the big orders we received in fourth quarter 2024?
Just really quick, Tony, the market share data is actually based on billing.
Yeah.
Yes. Yeah. The follow-up is like, when should we expect to receive more meaningful repeat orders from the leading HBM customer? I mean, or when should we can be expect that the orders can be maybe more significant than what we had back in fourth quarter 2024?
Yeah. I think it all depends on how soon they roll out in volume for 16-high. Right? Also that depends on their customers' rollout of the new architecture. The timing has to be aligned with ultimately how the ultimate customer roll out the GPU's architecture. I think as the industry move from 12-high to 16-high, I think all equipment supplier, including ourself for TCB, are waiting anxiously, you know, for that particular customer to allocate, you know, TCB demand. At this moment, you know, we feel that 2026 will be a year whereby, you know, there will be new tool demand TCB for 16-high.
Exact timing, unfortunately, Tony, I cannot give you any visibility at this point in time.
Yeah.
It cannot be too long, basically, in our opinion. Yeah.
Sure. Sure. No problem. Thank you, Robin. Thank you, Katie, for the presentation.
Thank you. Thank you.
Thank you, Tony. That will be our last question for today. I will pass the time back to Robin for his closing remarks.
Thank you for all your well wishes about my retirement. Now, before we end, let me capture some really key takeaway from today's discussion. First, 2025 was a year of solid execution for us and strengthening our customer engagement across the group. We delivered growth in both bookings and revenue with our book-to-bill ratio of 1.05 and a healthy backlog reflecting continued momentum and the trust the customer place in us. Second, AI-related demand was the engine of our overall business in 2025. Across both infrastructure and applications, AI drove significant activity in both SEMl and SMT.
This reflects an enduring structural trend that we expect to perceive, persist for some time as is, as it increasingly shapes customer roadmaps and priorities. Last but not least, TCB was a standout for us in terms of momentum and in terms of technology leadership. We expanded engagement in both Logic and Memory, securing wins across HBM, C2S, and C2W application. With our latest TCB TAM projection, this highlights the scale of the opportunities in TCB, and we continue to target a 35%-40% share of this market. In short, before I close, overall, we are well-positioned as we enter 2026. Thank you for once again for joining us, and we look forward to updating you in the next quarter. This concludes our call. Thank you and take care.
