Thanks, Steven. And hello, everyone, and welcome to ACM's Fourth Quarter and Fiscal Year 2025 Earnings Conference Call. I'm pleased with our fourth quarter results, which capped off a solid year of execution. Revenue grew 9% in the fourth quarter and 15% for the full year. We continue to execute well across our core business. We made a lot of progress with new product platforms, and we strengthened our position in China and globally. Investment in AI and data center infrastructure is reshaping the global semiconductor demand, shifting capital towards advanced logic, memory and advanced packaging. The industry is looking to key supplier for new technology, many of which have not yet been invented. ACM differentiated technology portfolio has been aligned well with this high-value process steps and the market is how -- now the market is coming for us for solutions. A good demonstration is recent momentum with several key global customers outside the Mainland China market that we announced in today's press release. First, we announced that we have delivered multiple single-wafer cleaning tools to Singapore facility of our Asia-based foundry customer. This marks ACM's first tool installation to Singapore, a key milestone for ACM. Second, we announced that we're receiving multiple orders for our advanced packaging tool from 3 global customers. This included orders for multiple-wafer level advanced packaging system from a leading global OSAT customer based in Singapore with deliveries scheduled for the first quarter of 2026. A panel-level advanced packaging vacuum cleaning tool from a leading global semiconductor packaging manufacturer based outside Mainland China, also scheduled for delivery in the first quarter of 2026 and multiple-wafer level packaging system from a leading North America-based technology customer with delivery scheduled later this year. Now on to our business results. Please turn to Slide 3. For the…

Thank you, David. Good day, everyone. Please turn to Slide 11 and 12. Unless I note otherwise, I'll refer to non-GAAP financial measures, which exclude stock-based compensation, unrealized gain/loss on short-term investments. Reconciliation of these non-GAAP measures to comparable GAAP measures is included in our earnings release. Also, unless otherwise noted, the following figures refer to the fourth quarter and full year of 2025 and comparisons are with the fourth quarter and full year of 2024. I will now provide financial highlights. Revenue was $244 million for the fourth quarter, up 9.4%. For the full year, revenue was $901.3 million, up 15.2%. Full year revenue was in line with our original guidance set a year ago and slightly above the updated range announced on January 22. Fourth quarter revenue for single-wafer cleaning, Tahoe and semi-critical cleaning was $159.9 million, up 3%. For the year, this category grew by 8.1%. Fourth quarter revenue for ECP, Frontend Packaging, Furnace and other technologies was $64.1 million, up 23.9%. For the year, this category grew by 32.1%. Fourth quarter revenue for Advanced Packaging, excluding ECP, services and spares was $20.5 million, up 23.8%. For the year, this category grew by 45.3%. I will now provide revenue mix by customer type for 2025. Starting this year, rather than disclosing specific customer names, we are now disclosing revenue by customer type once a year. For each customer type, this includes product, services and spare parts. We've included the mix table on Slide 7 of our presentation. For 2025, our revenue mix by customer type was split among Foundry, Logic and Other, 59%; Memory, 27%; Packaging and Wafer Processing, 14%. In 2025, we had 4 10-plus percent customers, including our top customer was 16.9%, next was 13.5%, then 11.6% and 10.2% for an aggregate total of 4…

[Operator Instructions] Our first question will come from the line of Charles Shi with Needham & Company.

I believe you gave pretty good color on shipment versus revenue growth this year. So I have a question since you mentioned about new products probably going to be a bigger driver this year for growth. And wonder if you can give us some color, let's say, excluding the new products, what's the growth, either shipment or revenue is expected to be excluding all the new products for the -- maybe -- I think maybe I'm talking about the existing product lines in cleans, plating, et cetera.

Okay. Okay. Thank you, Charles. And actually, you know that we -- as we said, we made quite a big progress, right, in the SPM process. Generally speaking, SPM, product SPM represent 25%, 30% of the cleaning market. And this market in the last couple of years, were not much touched so much. And as I said, last 2025, we made a very good progress both into the special module design for the high temperature and also Tahoe product. So we're getting to very aggressively into this market. And again, this is a very high-margin product and also a lot of customers, both in the Mainland China, also outside China, they suffered the particle issue with this high-temperature SPM process. And we think with our proprietary design model, we can control a very good environment, so therefore, can be -- will reduce particle size. So that can be really enhanced our market growth in cleaning. Secondly, I want to see that is our N2 bubbling proprietary bubbling wet etch technology is really critical for the 3D NAND silicon nitride etching process, which we believe our proprietary technology not only cover today's demand for 300-layer, we believe as people moving to 400 or even 500 layer will suffer this kind of uniformity on the wear top or wear bottom, right? So we're using large bubble and size. We also with our proprietary technology, we can make a very uniform and large bubble distribution in the tank. That will be really enhance the etching uniformity from the top to the bottom for the wear. So we believe that's not only demand in the market in China, we also see that demand outside in the global market, too. And third one, I also mentioned that is our supercritical CO2 Dry, we also made…

Maybe a question on profitability. So you reported last year, you gave some color about this year. But I believe if my math is right, your operating margin will compress last year from maybe close to 26% in '24 to 16% in '25. But this year, based on your -- what you guided about gross margin, what you guided about R&D, SG&A, it doesn't look like operating margin can rebound. It feels like operating margin probably more or less the same or even coming down a little bit depending on how the gross margin trends for the remainder of the year. So I wanted to get some sense how -- what's the reason for operating margin being under pressure for almost 2 years? And how do you plan to address this and maybe try to expand the operating margin from here?

Yes. Actually, that's this way. Looking at gross margin, right, we are the probably top of the equipment company in China, right, for gross margin, right, for the last few years. And as you said, Q4 of -- Q4 last year, we do see our first time gross margin is lower than our range, 40% to 48%, right? As we explaining maybe 3 factors. One is the product mix. We have 1 or 2 products, which is a semi-critical tool, do have pressure from the competitor for pricing there. The next one is really this inventory provision. But we think this year, as we are new product coming, as I mentioned, the 3 products coming will definitely enhance our margin. And also our inventory provision, we believe will be also greatly reduced too. So with that, we still have confidence we're in the 42% to 48% gross margin in this year or beyond. And more than that is, as you said, we put quite a bit of R&D last year, right? It used to be R&D 13%, 14%. This -- last year, we're getting to 16%. We probably will keep that number in a way. Why? The next few years, AI is driving a lot of demand for the new technology. And everybody else, first tier company outside China, all people put a lot of R&D. And so we'll continue to invest that, which we know will impact a little bit our operating margin, but it's worth to spend money now. Why? I said the opportunity is there, right? And a lot of customers real demand for the new technology, which I believe a lot of AI technology today even not invented yet. So it really give ACM a good opportunity with our, I call it our innovation power, our different technology, development capability, we can use this AI trend, we catch a lot of new technology and also catch the customer. This horizontal plate is one good example, for example, right? So again, and it's worth to spend more R&D and even get a few percent of the operation margin lower, which is a real long run, and we're working for the investor interest and also the growth ACM market into the next few years.

Yes. David, I might add a few things. I think that was a good overview. But Charlie, I think kind of summarizing it up, we're spending into the $4 billion market opportunity. There's a number of products that -- areas that we've been investing in that haven't scaled yet, but we expect them to scale over the next few years. It's the right thing to do to spend into that. You're right about the operating margin for 2026 kind of comes in at the mid-teen level, similar to what it was here in 2025. You move out a few years, our target is to keep those gross margins at that target range and then grow our top line faster than our OpEx. I think you can see some leverage in the out years.

Our next question will come from the line of Edison Lee with Jefferies.

Congratulations on the results. I just have 2 quick questions. Number one is that for the fourth quarter, the margin is a little bit low and the revenue growth also is a little bit slow and then your shipment, I think, declined on a year-on-year basis. So how much of that is just product mix and seasonality? And when do you think these numbers will actually start improving in 2026? And then the second question is about the USD 111 million you raised by selling down ACMS. Can you shed some light as to how you would actually utilize that proceeds?

Okay. So let's answer your first question, right? I think that you look in the -- I just mentioned last couple of years, our major growth engine from cleaning and also copper plating, right? Even the cleaning, I said there's one important product, which is SPM process were not touched too much. As I mentioned last year, end of last year, Q4 last year, we made a significant progress with this special nozzle design. We believe our performance is outperforming and top tier as a tool. So we see that growth continuously, right? And so then I would say our cleaning, copper plating and also horizontal panel continue to expand, too. So that keep momentum. Our cleaning market probably today in China about 35% range. We're expanding to 50%, 60% in the next few years. And the copper right now, the 40%, I still say we'll try to catch 60% beyond market in China. More than that is those product -- different products, we see a very high interest from global top-tier customer. So that's what we also reinforce our sales outside China. So that's where I see the impact or boost our revenue for our existing product. But -- and also, I want to see that through the last 5 years, we are really working with differentiated PECVD and Track and also Furnace technology, which we believe a lot of new technology we are putting in and nobody had it before, right? So that's what reinforce our, I call, market position. And plus those tool really with our differential technology, we put a lot of time to develop IP, develop the road map. It costs a little bit long time than the other guys. So -- and now it's come the moment for the market. And plus, I want…

Yes. Let me add on to something before you answer his question about our Shanghai stock sales. So Edison, for Q4, you probably remember last call, we mentioned that Q4 and the year -- the overall year came in at the midpoint of where we started the year, maybe a little bit better. And don't forget, we had 2 things. Our newer products didn't kick in, very little in 2025. And then we did have a customer push out from Q4 into 2026. And so that was kind of -- those 2 things that hit 2024 -- I'm sorry, the Q4. When you look out to 2025, we're expecting linearity pretty similar to -- I'm sorry, 2026, we're expecting our linearity to be pretty similar. So the first half will be about 42%, 43% of revenue. Second half will be 57% to 58%. But I would kind of anticipate Q1 at about 18% to 20% of the full year mix. Maybe, David, if you wanted to take this question, what are we going to do with the cash that we raised in -- or that we sold -- the cash that we sold.

Sorry, Mark, Mark, Mark, can you hear me?

Yes. Yes.

Before we move on to the use of proceeds, can you also comment a little bit on what you said about, I think, some products having some pricing pressure, which I think partially account for lower margin in the fourth quarter?

Yes. And there's not much to add to what I said there. Or what David and I have both said. There were a couple of semi-critical products that had particularly low margins that hit us in Q3 and Q4. And we -- David mentioned in the prepared remarks, he talked about the competitive situation in China. We are very focused on developing world-class tools. We think that there is also a bigger provision in the back half of the year. So we think that will be -- the overall provision for 2026 probably be smaller than it was in 2025, and it will probably be more balanced throughout the year.

Okay.

So you want me to touch the how we're using proceeds, right?

Yes.

Okay. Well, obviously, we have a second offering in China, right? Those money will be really focusing on R&D again, our expansion for their manufacturing. We have a second building will start decoration this year. So with that add together, probably we can manufacture $3 billion annually, which really give us a lot of room for manufacturing. And plus, we're also putting money in the mini line, as I mentioned, this mini line really speed up our internal R&D and debugging tool and also even can do the joint development with the customer process, too. So it's really well spend for those money. And the proceeds we got from the -- so the 1.3% from Shanghai here, definitely the major purpose for that was spending global customer, global marketing sales. So we see that opportunity really big in the global market. As I mentioned, we do have some differential technology might be the only solution for their AI challenging. So those products, we think will be really gather attention from the global customer. So we have spent money and building the international strong sales channel and also where we already had a Korea manufacturer base already. And however, with this geographic tariff going on, we have to really minimize the tariff impact, right? So that's why we started assembly tool in the U.S.A. So that will be real reduce our concern or any dynamic changing for those tariff will impact our revenue. So anyway, that's really what we work on. And our goal is very simple. We try to working with satisfy all regulation and requirement and maximize the investor interest, we're building a global sales, global company. That's our goal.

Our next question comes from the line of Jimmy Huang with JPMorgan.

Can you hear me?

Yes, please.

Congrats for the good results. I want to ask about we deliver single-wafer cleaning tools to a Singapore gas foundry. What would be the potential size of shipments in terms of units or dollars this year or next year and next year? This is my first question.

Yes. Very good question. Actually, we have a few tools, we're in the installation process right now, right? This tool will be qualified and go in production this year. And with that, we definitely will induce more of a cleaning tool. And also, we do have a copper plating and in -- behind. So that really will give us exposure of product in the Asian market. And so this will be real making more of, I call it, confidence and also get a high interest from other players in Asia and the market, too. So we see this will be a bigger milestone and for us, and plus we're not only looking at the customer only in Singapore, and we do have a customer in Korea and also we have a customer potentially in Taiwan. So we have really confidence we should have expanding quickly in the Asia market. And plus, again, we're also very focusing on our U.S. market, too. We do have advanced packaging tool PO and receiving and we should deliver by end of this year. And we see a lot of potential going on in the U.S. market, too. Again, because today, all the memory or logic, they are AI driven for their advanced technology. ACM, I want to say I feel good technology we needed for their production line. We believe that will be beneficial for the customer and also can help expansion of market to global. So it's a great opportunity because, again, innovation is a key and every customer and every key customer, they all demand for innovation technology, which will probably fit our strategy.

Yes. Yes. So for Singapore business, how is the chance that we penetrate to Singapore gas memory makers in the next few years? And my second question is for advanced packaging. We are making great process. But for Taiwan, Taiwanese foundries and OSATs are leading the panel-level packaging for AI GPUs . Could we talk about our POP progress with potential Taiwanese players? Do we have any like order forecast or purchase orders in -- from Taiwanese potential customers?

Yes. Actually, we are talking to a few key customers, right, even the panel large size, 515 x 510. And also, we're talking about their 310 x 310, right, which is a true vision right now, people try to push in. So we have very good exposure to those customers. By the way, April 7, 8, we have -- we're attending the panel conference in Taiwan. In that conference, we do the keynote speaker about the horizontal plating and also our vacuum cleaning technology. So that's really a lot of exciting, I want to say, interest coming. And also, I said -- I heard everybody say panel product or equipment, they're probably satisfy all other products, except plating. So plating become a bottleneck for their production expansion. So with that demand, I said we are the only one supplying horizontal plating. You probably heard that is the one key player in Taiwan, they said they only want horizontal plating. They don't want vertical. So our horizontal plating perfect fit their strategy or their demand. So as I said, really, we see a big opportunity and with our panel product. Actually, we're not only trying to introduce so far 3 products, right, panel plating, vacuum cleaning and also the bevel. We can develop also additional coater, developer, wet etcher, cleaning all kind of wet tool we are putting in. So that's really what we catch this wave of the panel, I call shift, right, for the advanced packaging. So we're in a very good position for those coming panel, advanced packaging expanding. We're very excited about this opportunity, right?

Yes. But do you know like in which kind of periods, quarters it will be more clear that whether we will have any order forecast or purchase orders for this POP equipment?

Well, let's put this way, we announced that we do have also PO from outside Mainland China, right? I mean we said already. So you know what I mean here. So -- and then we're continually expanding more, right? So again, I want to say this year, we have a confidence cash additional PO for our bevel, for our vacuum cleaning and also for the horizontal copper plating, not only in Taiwan market, we also see the opportunity in Korea, also in Singapore, by the way. So it's very exciting.

Yes. Maybe I can squeeze in my last question about the investor FAQ that ACM has disposed a small portion of stake in ACM Shanghai. How do we think about more further such disposal in the future? You mentioned that U.S. international capacity builds will require more funding. Will we dispose more stakes of ACM Shanghai in the future?

Repeat the question again. I'm sorry. Can you repeat again?

He's asking, are we going to sell more of our ACM Shanghai?

I see. I see. Okay. We sold 1.3% already, right? And we got a proceed of about $111 million. And we do have both arms to raise money. We can raise in U.S., we can raise in Shanghai. We're very flexible for what we're choosing, number one. And at this moment, I want to say our Shanghai stock is still -- we think it's still undervalued, okay, with our growth. So we maybe consider what the money demand and the time line, also what's the stock pricing in Shanghai. We decide where or when we should sell additional or not. And plus, as we have silver arm, we can raise the money in U.S.A. So it's quite flexible for us to raise the fund. And at this moment, I want to say, obviously we'll continue investing more in global market, and we have no concern for those money where it come from, right? We are very confident. We also have another , another tool we can get the money anyway.

Thank you. Seeing no more questions in the queue. Let me turn the call back over to Steven Pelayo for closing remarks.

Okay. Great. Before we conclude, I just want to give everyone a quick reminder on our upcoming investor conferences. On March 9, we will participate virtually in Loop Capital Markets' Seventh Annual Investor Conference for one-on-one meetings. On March 23 and 24, we will present at the 38th Annual ROTH Conference in Dana Point, California. Attendance at the conference is by invitation only. For interested investors, please contact your respective sales representative to register and schedule one-on-one meetings with the management team. This concludes the call, and you may now disconnect. Take care.

This concludes today's conference call. Thank you for participating, and you may now disconnect. Everyone, have a great day.
