Good day, ladies and gentlemen. Thank you for standing by, and welcome to the ACM Research Fourth Quarter and Fiscal Year 2020 Earnings Conference Call. [Operator Instructions] As a reminder, we are recording this call. If you have any objections, you may disconnect at this time. Now I will turn the call over to Mr. Gary Dvorchak, Managing Director of The Blueshirt Group, Mr. Dvorchak. Please go ahead.

Good morning, everyone. Thank you for joining us on today's call to discuss fourth quarter 2020 results. We released results after the U.S. market close yesterday. The release is available on our website as well as from Newswire services. There's also a supplemental slide deck posted to the Investor portion of our website that we will reference during our prepared remarks.

With that, let me now turn the call over to David Wang, who will begin with Slide 3. David?

Thanks, Gary. Good morning, and welcome, everyone, to today's call. 2020 was a very productive year for ACM. We are faced several challenges, such as the COVID-19 pandemic and trade tensions. We overcame these challenges through hard work and good execution and a positive tailwind in China semiconductor industry. We focused on what we could control. We managed our supply chain. We executed our customer deliveries. We expanded capacity. We introduced new products, and we made great progress with new customers. We also moved forward with our long-term facility plan in Lingang and completed the [apartment] for employee housing development. Before getting into detail, I would like to thank our employees for their hard work and dedication. I also want to thank our customers, partners and shareholders for their continued support and confidence in ACM Research. For the full year, we had a record revenue of $156.6 million, up 46% and a record shipment of 182 million, up 58%. Non-GAAP operating margin was 17.3%, and we ended the year with a $71.7 million in cash and additional $28.2 million from our holdings of SMS, STAR Market shares. Our success starts with our customer. Please turn to Slide 4. We have 5 major front-end customers across foundry and DRAM as well as several back-end wafer packaging and assembly customers. Our new customer, manufacturer of analog devices, they choose ACM technology to optimize their own production capability. We'll help them achieve the operational excellence they needed to compete in today's global semiconductor markets. Let me discuss our key customers. I will start with the Shanghai Huali and Huagong Semiconductor, also known as Huali Huagong Group. They are leading advanced foundry in China and our customers in 2020 and 37% of total sales. They are great customers and neighbors with production near on…

Thank you, David. Good day, everyone. Q4 was another strong quarter, capping off a tremendous year for ACM. For the full year, we grew our business significantly with increased market share, good customer exposure and expanded production at our second factory. We launched several major product lines, including the Furnace, semi-critical cleaning, introduced a number of extensions for SAPS, ECP and advanced packaging. We closed the year with a solid balance sheet, including $72 million in cash and an additional $28.2 million of trading securities of our SMIC stockholders. Now I'll put some detail around our full year 2020 results. Unless I note otherwise, I will refer to non-GAAP financial measures, which excludes stock-based compensation, change in fair value of financial liability and unrealized gain in trading securities. A reconciliation of these non-GAAP measures to comparable GAAP measures is included in our earnings release. First, highlight and the results for the full year 2020, shown on Slide 8. Revenue was $156.6 million, up 46%. We break out 10% customers annually and provide occasional color on our quarterly calls. As David noted on Slide 4, we had 3 10% revenue customer for 2020. First, the quality Huahong Group together accounted for 37% of revenue versus 26.5% in 2019. That grew by 103%, a big contributor in growth as we expanded penetration from Huali Shanghai fabs to additional factories of Huahong and Wushi. YMTC was our second largest customer at 27% of revenue versus 27.5% in 2019. Our revenue from YMTC increased by 42% year-over-year. To help expand by YMTC to expand their wafer starts to $50,000 per month and summit share gain into additional cleaning steps drove the growth. SMIC was 12% of revenue versus single digits in 2019 and the participation, with SMIC improved nicely in 2020, due in part…

[Operator Instructions] We have the first question from the line of Patrick J Ho from Stifel.

Congrats on a nice finish to the year. Maybe, David or Mark, looking ahead,at local Chinese domestic spending, we're looking at potentially another strong, robust year. Can you just give a little bit of color of the breakdown between your thoughts on memory spending versus the trailing edge foundry logic spending and whether you see potential growth in both areas? Or is it going to be weighted more on one segment or the other?

Okay. Thanks, Patrick. Actually, we have very good availability in our basic 3D NAND and also [1Q3] and also Huagong Huali. And so we see that continuing to -- quickly spending their fab, both in the advanced 3D NAND the demand, also the memory side, also in the logic foundry side for Huagong Huali Onion group, right? And plus, they also acquire their -- so this 5, what we call the second-tier customer. And there, we got 2 already. And this year, we have companies who will get rest of the 3 additional second tier, I call it, training edge, the customer tier. So we're building favor lately. And I still say probably mature -- more than 50%, 50%, they come from top or first 3 customers. And we're seeing that there are 5 additional new customers expanding quickly. We cannot give a precise number of the next -- this year, what the region will be. But obviously, of course, they're going to expanding their fab. Mark, anything you want to add on?

Yes. No. Thanks, Patrick. I mean, I think you asked about the relative growth versus memory and trailing edge. And as you know, YMTC is a 3D NAND big customer, so we're expecting to grow it there, their capacity adds. David mentioned to Huali Huahong, SK Hynix, David, in the prepared remarks. We're anticipating a DRAM recovery from them. And so they were less than 10% in 2020. And so we'd expect them to kind of get -- kind of show some decent growth here in 2021.

Great. That's helpful. And maybe as my follow-up question for you, Mark. As you get the new facility and factory ramped up,for production, how do you look at gross margins given that there are typically startup costs, some underutilization to begin with? How quickly do you get that within to your normal, I guess, corporate ranges as that facility ramps?

Yes, you bet. So Patrick, we're not going to modify our gross margin outlook, kind of the 40% to 45% range, right? There's a lot -- obviously dependent on the product mix, and that's really the biggest driver. Relative to production capacity, we said a bit here. Chuansha, we're adding capacity pretty quickly. We've got really pretty good demand throughout the year. The Lingang facility, that -- we're looking at that for the end of 2022 is when that would start kicking up. So we don't really anticipate any impact to our gross margin from that Lingang. That will be out there in 2023 and beyond.

We have the next question from the line of Suji De Silva from ROTH Capital, please.

David, Mark, congratulations on a strong end of the year. A quick question on the STAR listing. Can you just give us a sense qualitatively the level of detail the SEC requested in this additional review versus the original report you filed? Just give us sort of some sense of magnitude here of how much more they're looking for.

Okay. I just stated, right, this short seller report had come out, and we spent almost like 2 months to finish the report. And then we got accepted, and almost we're starting to acquire we call it registration for CSRC, but then there's a lawsuit to come up, right? And anyway, now we're taking care, also we hired their very experienced lawyer in the U.S. And lawyer told us pretty much no substance in the lawsuit right now. And so we're going with -- again, in response to the report to SEC, to give them the detail what is going on, what is legal process in the U.S. I think it probably is going to [indiscernible] very soon, and then we're waiting for their response, how they think about this. If it's a positive report, then we can start continuing the registration process in the CSRC. So that's the timing right now. But again, we don't know how long for there to resume our second report. And that's why we couldn't give precisely timing of the IPO. But I think we're confident. I think we get over almost 90%, 95% down already, and the remaining 5% of them we are pretty confident. We should have been a success with IPO based in China.

Okay. And then perhaps on the financials, the tools you have placed with customers entering '21. Maybe -- I'm curious, do you have a higher percent of visibility from those tools into your guidance for 21 versus, say, a year ago, given that you have more customers and more products?

Yes. I can see that this year obviously is better than last year, right, and looking at our projection. And also, as you are aware, we're very busy on the Q1, Q2. Even we're really stretching kind of plating and very [indiscernible] the manufacturing capability. So we start to hire more people and also training more people and to final path also to the Chinese New Year. So at this moment, it's very busy Q1, Q2 including Q3. So we're very -- I call, very confident in -- for our projection for this year.

Yes. And Suji, you could obviously look at the level of the finished goods inventory, right, at the end of last year, the end of 2020. And so it grew from, what, $19 million to about $32 million. So -- and that's carried at cost. So assume our corporate gross margin for that to get an idea for how much revenue visibility would be there.

We have our next question from the line of Charlie Chan for Morgan Stanley.

So my question is about your China customers' contribution. You mentioned about YMTC and Huahong. But how about SMIC? And because the company also announced they want to spend around USD 4.7 billion CapEx. Do you think that is going to be a significant growth driver for you for this year? And what do you think about their capacity expansion progress given the SAPS issue?

Okay. I think we're pretty well positioned with SMIC, and we have worked with for the last a 3 or 5 years. And we do have a product and so then in cleaning and there is our -- I got key process and SAPS. And also, we also have, I call it, semi-critical process also being sold to SMIC. We also do have copper plating and also our TSV tool, right? And plus also feature -- also position our Furnace tool into the SMIC too. So I think we're very positioned for the market now. And looking in their announcement, they're expanding 10,000 per month of their, call, it all the revenue expansion for their probably 128-nano technology. So we are positioned for that too. Again, if this licensing can be solved quickly, we can see quite a tremendous opportunity in front of us. However, this moment, were still very cautious watching and [indiscernible] of stuff. And obviously, the without there license ran down and for them to be expanded quickly, it's kind of difficult, right? So anyway, this moment, we just help and are working closely and -- even just our customers. So we're making good, supporting service for the company.

Yes. Charlie, one thing I'd add, right? I mean, it's obviously a bit of a wildcard, right? I mean, we've got -- David mentioned really good visibility with a number of our top customers. But for SMIC, we're not factoring a significant amount in our outlook. It really depends on their ability to get tools from other U.S. manufacturers. So -- and that, demand in China is pretty strong across the board. And we also think that it's mixed depending on how much capacity they add and some of the other manufacturers may add, may step up their spending. It's hard to tell, but for them, we're not going to factor too much into our outlook.

The next question comes from the line of Quinn Bolton from Needham & Company.

So let me -- my congratulations to the strong finish and the nice outlook for 2021. David, wanted to kind of follow-up on Suji's question around the SEC review. I understand you're about to file your response with more information about the class action lawsuit. And you don't know how long it will take the SEC to review that. But once you receive that -- or once the SEC has completed its review, can you walk us through how long does it typically take to get through the CSRC registration process? So folks can have a sense of time, that once that SEC review is complete, what the time line for an IPO might look like? Is it order of weeks? Is it a couple of months? Any thoughts you could provide would be helpful.

Okay. Quinn, very good question. And actually, as I said, when the SEC finished a review for a second report, then we're getting into the so-called registration for CSRC. And by the -- I should say, so far, the statistic data show averaging registration time in CSRC, about 45 days to 60 days. So that will be the registration time period. And after that, we'll probably spend the other decision down because another 2 weeks or 3 weeks, the road shows. That you can -- kind about the 2 to 3 months, right, IPO time. That's after we finish the acceptance or approving assets we're seeing for secondary report. Did I answer the question?

Got it. It's perfect, yes. And the second question is -- a very nice job on the shipments in the fourth quarter. Mark, I believe I heard you say $67 million. Obviously, that gives you some pretty good visibility into 2021. I'm wondering if you might be able to break down for us, how much of that $67 million were your kind of traditional critical clean tools versus some of your newer semi-critical Furnace, ECP tools? Is the majority still the critical clean? Or are you starting to see a much broader kind of composition of the shipments you're making?

Yes. Maybe I couldn't give you the sort of detailed numbers. I can give you a general. Probably cleaning tools, they occupy about 85% -- 80%, 85%, I call the total cleaning our, I call, flagship, also semi-critical together. The rest of it, 15%, 20%, is our new products coming, copper plating. And also, we have application in the packaging application. So that probably gives you the ballpark, 80-20 divided.

The next question comes from the line of Chi Tsai from Jefferies.

So you reported to deliver $188 -- $182 million shipments in 2020, and I think that would indicate $31 million backlog in 2020. And I think if I'm getting right, I think you now have more than $60 million backlog. And do you see this backlog, well, expanding in 2021? Or you're expecting the similar range?

Yes. Yes, let me just correct a few things. So the way you would look at the value of our tools that are awaiting acceptance, right? You'd want to look at the finished goods inventory level, not the number that we shipped in the year. But that finished goods inventory was a little over $32 million, right? So that's carried at cost. So would assume the corporate gross margin to get an idea for the level of potential revenue that's in that. And so I think what you may be asking, for 2021, we don't really give guidance on our overall shipment. But we would anticipate strong shipments again -- shipments to additional delivery of demo tools this year.

Yes. Well, obviously, this year, there's more new customers coming in, especially, we have a new product in SAPS, and also our Furnace product and also additional new customer come in, we're expecting more other, I call, deferred revenue will come out this year, too, which is recorded -- not recognized, immediate upon shipment, but we recognize revenue upon acceptance. So this year, I expect the end of this year, much more first tool could be deferred to the next year.

I see. My second question is that, can you kind of bridge the outlook of 2021 revenue in first half and second half? Because I think a lot of capacity expansion plan, like additional expansion plan were made in the second half last year due to opacity shortage. So I think more capacity will be delivered in second half. So I think, can you give us some idea on how first half and second half will look in this year?

Yes. I think I can address that. I mean, we typically give a full year outlook. But Q1 is typically our seasonally weakest quarter, right? You got Chinese New Years in there. So yes, we get a nice -- generally a good snapback in Q2. Q3 has traditionally been our biggest quarter, and then a slight decline in Q4. So that's how we're looking at it. And I think you're correct, a little bit more in the second half than the first half, kind of balance that way. But nothing traditionally out of the ordinary from the seasonality you've seen in the last year.

The next question comes from the line of Mark Miller from Benchmark Company.

You indicated you expect the return of Hynix to 10% customer. Is that more of a second half or a first half type return?

Okay. I think that -- I think, look, probably in the second half of this year. And we do have some order coming in the Q1. And also look at the market, and the people project that DRAM will be quite recovered compared to last year. So we're expecting some other order coming into the second half of this year.

Your sales and marketing expenses were up significantly -- I'm sorry, your sales expenses were up significantly, sequentially as well as R&D despite somewhat lower sales in the fourth quarter. Do you expect this trend to continue into 2021?

Yes. I think we're using the number, our sales marketing, about 9% to 10%. And that range will keep -- continue. However, this year, we do add additional, probably, 3-point and more for R&D. So it totaled about 14% and plus R&D efforts because as we mentioned, it's a very pivotal year. So it's a few year for ACM flow. And it's critical we are positioned strongly in the Asian market, and that's why we're investing more to develop new product come outs. And those give more spending for R&D.

So you said sales will be about 10% roughly?

Yes. It's 11%, 10% sales marketing. And then we're funding more of the R&D business until the G&A. That's the total spending for the brand.

Yes, Mark, just to make sure you're aligned, this is the non-GAAP, right? So we're excluding the stock-based compensation, those percentages that Dave was giving you.

Yes. You mentioned stock-based. What was stock base comp last quarter?

Q4 stock-based comp was $1.3 million, $5.6 million for the year.

We have a follow-up from Charlie Chan for Morgan Stanley.

Yes. Charlie, I think we cut you off somehow or maybe we lost you.

Yes, yes. Sorry, I got disconnected, working from home. So maybe another follow-up is for you about your international customer progress. I know Hynix probably will be 10% this year. But how about other major Chinese -- Huagong, TSMC or other U.S. customers? Any progress here?

Great. Charlie. So let me maybe elaborate, Charlie, on our next big plan, coming to the outlook for these customers. And we're always looking 3 and 5 years ahead, what's the technology trend today in the industry, people talk about all the gain or loss and also the 3D probably come to the real limitation to nano, when nano is really hard and also very expensive, too. So people on the 3D. Now I can say 3D NAND is of the structure people are talking. And people are talking about 3D DRAM and advanced packaging. So I look at the trend ahead. ACM is really well positioned for this huge technology trend. As a part of our cleaning tool, our SAPS, TEBO is really good for cleaning. TEBO is only technology today in the world that can reassess tiny [indiscernible] tiny particle inside deep change in [ arrear ]. That's only available as to the market, and you can clean those deep or tiny corner particles. And by other technology like [ Jet3 ], you never can get out. And also, the [ megasonic ], we make this kind of a limitation. Then the particle graduate out of the structure, right? So that's the one where we're positioned for that. Second one, I see that the 3D, the major applications down the road, a lot of multilayer interconnection and also 2.5 3D connectors, including TFTE for the 3D DRAM. So our covered 3D technology is very, very positioned for that. A recent progress on the high-speed copper plating. And I think our key point is going to reach 3% for the right top-tier profile. And that real attractive intention from the top tier customers. And also another one as polishing. We talk about we can polish copper in much less…

Yes. The only thing I'd add, Charlie, is that this year, we wouldn't -- we didn't factor any revenue from these big customers -- from this new customers into this year's outlook.

Okay. Okay. Sure. And this question really is for Mark. I guess, a very -- 2 questions. First of all, the postponement of the IPO funding, that impact your funding for the new business or new trends, et cetera. Any impact to the operation? And how soon do you think that something needs to be ready before that impact your business plan? And second quick question to Mark is really about the OpEx ratio guidance or your op margin guidance for the half of this year or for the coming 3 years.

Great. Great. Yes, I'll hit that. So on the China IPO timing, as David said, the progress is -- it's not under our control. So we're doing what we can to support. We're confident we'll complete it. Hopefully, it will be soon. But our business plan doesn't require an immediate IPO. And we talked about our CapEx plan, $10 million to $15 million, for this year. We would adjust it upwards after the IPO to spend more on Lingong. And what we're doing, right, we feel like we've got plenty of room to add capacity in Chuansha. We're looking at other options there. But we feel quite well funded, and our plan doesn't require the immediate funds here. In terms of the OpEx levels for 2021, David talked about the R&D you got to think about our model, 40% to 45% on the gross margin. It kind of gets you to about a 14% op margin on a non-GAAP basis for the year.

Okay. So that means the OpEx ratio is around 30%?

That would be right. Yes. Yes.

Yes. Again, we really balance growth versus visibility. At this moment, I rather spend a few points higher for R&D. And then we reduced a little bit profitable rate. That will be really good for our -- grabbing the market and also lead straight to our position. And that, I think, our philosophy behind it.

We have the next question from the line question from Christian from Craig-Hallum Capital.

Great. Actually, the last few questions were the questions I had. So congratulations on a great outlook. I don't have any further questions to ask at this time.

Okay. Thank you. Great.

Thank you. Seeing there are no more questions on the queue, I would like to hand the call back to our presenters for some closing remarks.

Thank you, operator, and thank you all for participating on today's call and for your support. This concludes the call, and you may now disconnect it.

Okay. Thanks, everybody.

Thank you. Ladies and gentlemen, that does conclude the conference for today. Thank you for participating. You may all disconnect now. Thank you.
