ACM Research Inc (ACMR) 2021 Q2 法說會逐字稿

Good day, ladies and gentlemen. Thank you for standing by. Welcome to the ACM Research Second Quarter 2021 Earnings Conference Call. (Operator Instructions) As a reminder, we are recording today's call. (Operator Instructions)

Now I will turn the call over to Mr. Gary Dvorchak, Managing Director of Blueshirt Group. Mr. Dvorchak, please go ahead.

Thank you, and good morning, everyone. Good evening in China. Thank you for joining us on today's call to discuss second quarter 2021 results. We released results after the U.S. market closed 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'll reference during our prepared remarks.

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

Thank you, Gary. Good day, and welcome to today's call. We had another productive quarter with solid financial results. We delivered record revenue and shipments with good profitability.

Second quarter results reflect ACM growing customer base, technology leadership, expanding product line and increased production scale.

Revenue grew to $54 million, up 38% year-over-year. Shipments were $82 million, up from $45 million in the second quarter of 2020. We delivered a good balance of growth and profitability, with 40.5% gross margin and 10.4% (sic) [10.5%] operating margin. We are committed to drive profitable growth as we increase our investment in R&D to drive innovation, further strengthening our existing product portfolio and grow our addressable market with new products.

On the bottom line, we reported $0.19 of net income per diluted share compared to $0.29 in the same period last year. We ended the quarter with $70 million of cash. In addition, we hold SMIC's stock market share was $31 million as of quarter end.

I will now discuss the recent operational highlights on Slide 3. First, our Q2 revenue growth was broad-based, driving by current and new products and current and new customers. Our wet cleaning and other front-end process tools represent 85% of total sales in Q2. We had a good growth from our flagship SAPS product with incremental contribution from our semi-critical tools, advanced packaging, other products service and spare grow significantly to 15% of sales versus about 3% last year.

The strong growth of this group was driven by advanced packaging tools, including wet etch, stripper, developer and colder and a big increase in our service and spare part business. This first-generation in semi-critical and advanced package tool accelerated our revenue growth and further strengthening our position as a leader supplier in the China semiconductor industry. The higher mixing of this product, however, partially dilute our gross margin during this introduction stage.

We enter this new market segment to capture the strong demand from our China-based customers and to deepen the moat that easily our flagship product from competitors.

In cleaning, our newer semi-critical tool, the ACM flagship SAPS, TEBO and Tahoe products to cover more than 80% of the total cleaning market opportunity. In advanced packaging, our newer ECP ap product line expanding our current portfolio with highly differentiated products. Put it all together, we remain committed to our 40%, 45% corporate gross margin target.

As a part of our normal product management, we expect improvement in gross margin for our semi-critical and advanced package group. This will come from tightening feature content as we early model and data our range of options for customer evaluation and cost reduction in later generation models. We also expect a cost benefit from volume production.

Meanwhile, gross margins for our flagship cleaning products remain consistent with the past period, which we expect to continue. ACM strategy is to enter a market with advanced differential products, such as our flagship cleaning product, our ECP tools, advanced foundry stores and other new innovative product. This product allows us to win major customers and provide us the profits to fund the future product developments. It also allows us to enter middle range or lower end products that may come with a lower margin in early stage, but allow us to capture a much larger market opportunity as we scale the business. We remain committed to our gross margin target, which we believe we can achieve by balancing continuous innovation at high end with disciplined product management cost, engineering and production scale.

Let's turn to Slide 5 to discuss ACM growing customer base. We have 5 major front-end customers in foundry 3D NAND and DRAM. In 2021, we expect Huahong Group and YMTC to remain our top 2 customers. We expect good growth from them this year. However, each may represent a lower percentage of total revenue as we expect to see significant growth from other customers. We also expect the contribution from SMIC, SK Hynix and CXMT.

Importantly, we recently received new orders for several tools from SMIC for the second half of the year. During the past 12, 18 months, our team has done a great job of broadening ACM tool content at SMIC, including a full range of cleaning products and our ECP tools. We are getting indication of higher demand from SMIC in 2022, but it is still early. SMIC demand is subject to further licensing progress by them with other U.S. equipment supplier.

We recently added a number of new China-based semiconductor customers, who manufacture power, analog, CMOS image sensor, compound semiconductor and other devices. This customer, including 4 of 5 Tier 2 players and a handful of new Tier 3 and other customers. Although, it is a relative small that new Tier 2 and Tier 3 customer as a whole could contribute 10% of more 2021. As newer customers are investing in new capacity to support the growth of IG, ALT and EV technology. ACM has good penetration with a range of tools, including SAPS semi-critical cleaning ECP and the furnace products.

Our third customer growth is advanced packaging and other processing customers. Top customers have, including JCAP, Tongfu, Nepes and Wafer Works. In Q1, we discussed the order from 2 advanced packing house, and we now expect to add more customers as moving through the year. Collectively, we expect a significant growth from the group driving by increased industry focus on advanced packaging penetration of new customers and a new product cycle for ECP ap tools.

Looking ahead, we believe that our current customer base represent a significant opportunity for ACM. Most of these customers are still in early or middle age -- middle stage of the multiyear capacity expansions. We remain committed to further broadening our customer base as we believe every major semiconductor manufacturer can benefit from our technology.

Please turn to Slide 6. We delivered total shipments of $82 million in the second quarter, a new record in the company's history. Shipment in Q2 were [$828 million] higher than revenue. The difference largely represent shipment of first tool awaiting customer acceptance. We view this as a positive indicator as it is reflect demand for new products and from new customers. This level of shipments is a testament to ACM production team in our Chuansha factory.

We are scaling capacity to meet strong customer demand in a generally highly supply chain environment. Our in-house high-performance factory and the strength of our manufacturing team are helping us manage near-term supply chain constraint. That gives us confidence in our ability to navigate environment entering the second half of this year.

We plan to begin production in the second building of our Chuansha factory in the third quarter of this year. We have increased our capacity plans and now our targeted run rate exiting Q4 of this year that represent more than $500 million of annualized production capacity up from $350 million at the beginning of this year. We expect to further increase production capacity in 2022.

Our long term plan is built production and R&D center in the Lingang region of Shanghai, the 1 million square feet of floor space will enable us to increase our annual production capacity to USD 1.5 billion. We completed additional architecture and design work in the second quarter with initial production now start in the beginning of 2023.

Please turn to Slide 7. We continue to invest in new products to broaden our offering. Today, I'm pleased to announce TEBO achieved extension to our weather product line. This product using a wet etch method to remove dielectric metal and organic materials films as well as contaminants under wafer edge. ACM edge approach minimizes the impact of edge contamination for later process steps and thus, improving manufacturing yield.

The Bevel Etch product leverage ACM's wet processing expertise to deliver performance benefit compared to joint approaches. In the consumer less chemical and support a broad range of device types and process steps, including 3D NAND, DRAM and advanced logic process. We expect to ship our first tool for high-volume manufacturing to China-based logic manufacturer this quarter.

Additionally, with ACM proprietary technology, this new Bevel Etch product can achieve more accurate and efficient wafer centering alignment. This will enable our precise Bevel Etch and it will enhance product yields and wafer throughput. In addition, we are currently developing advanced technology to deepen our leading market position in cleaning, which we will add more products to our portfolio in 2026.

We remain polishing our ECB product line in from and smaller geometry require advanced plating solution. Meanwhile, back-end advanced packaging are becoming more important as industrial looks for packaging innovation to drive a higher performance as the industry moves beyond more so.

Our ECP product line indicates ECP map, a front-end tool for damaging copper interconnection, the ECP TSV for through-silicon via also for front-end and ECP ap for advanced packaging, we believe the total global market for ECP will triple from $500 million last year to up to $1.5 billion in the coming years. Although, we did not (technical difficulty) revenue in the second quarter, we delivered 3 first 2 to 3 customers. We expect to deliver higher volume ECP tools in the second quarter -- second half of this year, with a good revenue contribution from repeated shipments in Q3 and Q4.

We also continue to see strong interest for our Ultra Fn furnace joining process tool portfolio. We delivered several first tool, including TEBO and non-TEBO party at LPCVD in the first half and expect to deliver additional units as we progress through the year. We remain on track to add a high-temperature oxidation and neoning capability to our furnace product line in the third quarter of 2021.

Building on that, the next major development in our furnace road map is to the batch atomic layer separation or ALD process. We view this as the most challenging and promising product for advanced manufacturing nodes. We expect the furnace product cycle to become more meaningful in 2022 time frame.

We are making significant R&D investments in 2 major new products categories to achieve our goal of doubling our total addressable market from $5 billion today to more than $10 billion. We continue to bring in top engineering talent to support these programs and are confident our team will deliver products and move forward with customer evaluations on the first product line in the first half of next year and the second product line in the second half of 2022.

I'm happy to report we made a good progress with the potential U.S. and Taiwan-based customers since our last call, despite the COVID-related travel restrictions. Our team is heavily engaged in business development. We are confident that we can secure orders from at least 1 new major first tier global semiconductor manufacturers in 2021.

Before I provide our updated 2021 outlook, let's discuss the status of the stock market IPO of ACM Shanghai. We continue to make good progress. On June 10, 2021, the Shanghai Stock Exchange Commission submit the ACM Shanghai's application for registration with stock market IPO to China Securities Regulatory Commission, CSRC, moving us step closer towards our goal. We are hopeful that the CSRC approves and complete our registration soon. When we receive CSRC approved, we estimate that the issuance process will take another 1 to 2 months. Keep in mind that the timing is subject to numerous factors outside ACM Shanghai control. We are confident that eventual stock market is being combined with our NASDAQ listing can provide a strong foundation to accelerate our mission to become a major global player in semiconductor equipment industry.

Now let's move to our 2020 outlook on Slide 8. Our guidance reflects optimism about our growth opportunity for 2021. Based on our strong results through the second quarter and improved visibility for demand and our supply chain through year-end, we have rich outlook for the full year. We now expect the revenue to be between $225 million and $240 million, up from the prior range of $205 million to $230 million. The revised revenue range represent 48% annual growth at the midpoint.

Our updated outlook for 2021 is based on several key assumptions: first, the global COVID-19 situation continues to improve; second, the stability in U.S.-China trade policy; third, a range of spending scenario for the production ramp of key customers; fourth, variance in the trajectory of the DRAM recovery; and finally, a range of timing of customer acceptance of first tool.

Our results and outlook demonstrate the successful execution of our strategy. Our strong growth is supporting additional R&D spending on new products. We are building our global sales and marketing resources to penetrate new customers in new regions, and we are scaling production capacity to support our long-term growth plan. Our mission to become a major equipment supplier to the global semiconductor industry remains on track.

To conclude, 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.

I will now turn the call over to Mark to discuss the financial results in more detail. Mark, please?

Thank you, David. Good day, everyone. We delivered solid financial results in the second quarter. Unless I note otherwise, I will refer to non-GAAP financial measures, which excludes stock-based compensation and unrealized gain and trading securities. A reconciliation of these non-GAAP measures to the comparable GAAP measures is included in our earnings release.

Now on the second quarter shown on Slide 9. Revenue was $53.9 million, up 37.9%. Revenue for single-wafer cleaning tools, which include SAPS, TEBO, Tahoe and our semi-critical cleaning, was $45.5 million, up 36.4% from $33.3 million.

We had no revenue for ECP furnace or other technologies during the second quarter. As David noted, however, we delivered 3 first tools in the quarter, and we expect more revenue contribution in the back half of the year.

Revenue for advanced packaging, excluding ECP, services and spares, was $8.4 million, up from $1.2 million in 2020. Total shipments were $82 million versus $45 million in the second quarter of 2020 and $74 million in the first quarter of 2021. This includes deliveries for revenue in the quarter and deliveries of systems awaiting customer acceptance for potential revenue in future quarters. This represents another quarter of record shipments, a great accomplishment by a production team given industry-wide supply constraints.

Gross margin was 40.5% versus 49.7%. This was at the lower end of our normal expectation range of 40% to 45%. The decrease in gross margin, as David mentioned, was due in large part to product mix. We expect gross margin to continue to vary on a quarterly basis due to a variety of factors, including product mix and manufacturing utilization.

Operating expenses were $16.1 million versus $11.2 million. The increase in operating expenses reflected higher R&D on new products, our expanded U.S. sales team and legal costs related to our U.S. civil suit and the China STAR Market IPO.

R&D expenses grew by 52% to $7.7 million or 14.2% of sales versus $5.5 million or 12.9% of sales last year. The increased R&D intensity reflects ACM's commitment to new products and innovation. We expect to continue to increase our R&D spending in 2022.

Operating income was $5.7 million, down from $8.2 million. Operating margin was 10.5% versus 21%. Unrealized gain on trading securities related to the change in the market value of our SMIC investment was $3.8 million in the second quarter of 2021. Note that we exclude this noncash item from our non-GAAP results.

Tax expense was $15,000 versus $1.9 million in the year ago period. Net income attributable to ACM Research was $4.1 million versus $6.2 million in the year ago period. Net income per diluted share was $0.19 compared to $0.29 in Q2 of 2020. Tax items and the effects of foreign exchange fluctuations on operating results provided a net headwind of $0.3 million or $0.01 per share in the first -- in the second quarter of 2021 versus a net headwind of $0.9 million or $0.04 per share in the second quarter of 2020.

We'll now review selected balance sheet items. Our cash balance was $70.2 million at the end of the second quarter versus $78.8 million at the end of the first quarter. In addition to the cash balance, we also had trading securities of $31.3 million related to our SMIC investment. This includes a significant unrealized gain from our original purchase price. Total inventory was $136.9 million at the quarter end, up by $33.6 million from the prior quarter.

The quarter-on-quarter increase was driven by 2 items. First, finished goods inventory grew by $68 million to $64 million. This represents first tools that have been delivered to customers for evaluation and are carried on our balance sheet at cost pending potential customer acceptance. The second item is work in process and raw materials, which in total grew by $16.8 million from the prior quarter. This was due to purchases to support shipment growth expected for the remainder of the year.

Short-term borrowings at quarter end were [$22 million,] down from $23.5 million at the end of the first quarter. Long-term borrowings were $18.7 million, up $1.3 million from the first quarter. Cash flow used by operations was approximately $10 million for the second quarter, but it was slightly positive for the first half of the year.

For 2021, our base case plan for capital spending is about $15 million. This includes $2.8 million already spent through the first half of the year. Our 2021 investments will be primarily focused on capacity increases at our Chuansha factories, investments to support our R&D programs and planning and some initial spending on Lingang.

In sum, we continue to execute on our strategy. We are providing -- we are participating in the growth of major new IC fabs. We're ramping production, and we're developing and delivering new products to a growing list of customers. We're positive on our opportunities in China and expansion outside of China. We remain committed to achieving our mission to become a major player in the semiconductor equipment market.

Let's now open the call for any questions that you may have. Operator, please go ahead.

(Operator Instructions) We have our first question comes from the line of Patrick Ho from Stifel.

Congrats on the great outlook. Maybe for David or Mark, the semi equipment industry has gone through a lot of supply chain constraints over the past quarter. Given your results and your outlook, it looks like you're managing through it very well. And can you just qualitatively give a little bit of color on whether you're seeing any supply constraints, your supply chain is probably a lot different than some of my American companies. But I was just wondering how you saw supply chain constraints during the quarter or if any going forward?

Okay. Thank you. Actually, you can see that the market is moving, the component of supply is getting tight and tight, right? So we do see some long-leading items get further longer. So the only way we manage that is that we're -- based on our projection sell in the half year and even beyond. And then we're looking for the early ordering or early purchases, right? And there is a long-leading item. So we do see some components getting longer, which impact us. However, we get a pretty much good control. And we'll continue to see that, hopefully, this should get improved. And at this moment, we feel comfortable about our revenue this year. And actually also, we're also confident about also our shipments this year, too.

Great. That's helpful. And maybe it is my follow-up question for Mark. Gross margins between the 40% to 45% range. A lot of moving pieces every quarter. As we look at the high shipments in relative to cleaning tools first-time tools to customers, how do you balance that versus your overall, I guess, normal operations because if you get a quarter of multiple systems, that could weigh and pressure on gross margins and take you out of that range. What are some of the steps that you're taking to try and ensure that the gross margin still your seeing the expense array given the number of first tools and evaluating it out in the field?

Great. So yes, Patrick, I'll comment on it and maybe, David, if you wanted to add to it. Look Patrick, it's an art and a science certainly. I mean, right now, demand is quite strong, and so we're focused on our production. We do what we can, of course, to balance our revenue items versus our shipments -- our first tool shipment items and to balance the gross margins.

But many times, really, it's -- we -- our customers have strong demands, and we do what we can to support our customers. So we are -- it's very important for us to focus on innovation at the high end, but then we're also moving to deliver some round out the product market to create a moat between us and our competition. So we do feel very comfortable that we can balance all the items to deliver the gross margins in the range in the 40% to 45% range.

David, do you want to add anything to that?

Yes. Actually, you mentioned quite a bit good. I want to add there something really in this moment, I think, for us, we want to get the balanced product portfolio, right? And you'll see that, say, a year ago, most of our shipment is a single-wafer cleaning and those are normally higher margins. And those margins still keep not changing. As we introduced semi-critical products, and also more of an advanced tool in the packaging, and they're spreading lower-margin product come out, right?

So we combine together, that's kind of a margin you see the dilution. However, as we continue to mature our products, even in the semi-critical tool and also control our cost for manufacturing, also scare production plus where additional innovation product ECP continue to mature sell and also advanced wafer furnace come out. And so we'll see that ban is continue, right?

So we believe at this moment, we try to also secure our position and also especially keeping competitors getting to our flagship product. It was to get this semi-critical or other relatively low profile products. However, as I said, with our confidence with also future innovation, keep growing even add a new cleaning function, more of a new feature even to our cleaning major product, then we'll see better margin eventually get back, right? We're still confident in 40%, 45%. And as I said, continued innovation and new product development that will helping our margin keep growing in the range.

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

On the ECP sort of outlook and hoping you might be able to spend just a little bit more time, talking about the ramp that you expect for ECP, maybe if you could give us a sense how many tools you have, ECP tools you have waiting customer acceptance and any thoughts whether ECP might be able to get to 10% of revenue next year? Or is it ramps and customers accept tools?

Okay. Okay. You're looking at ECP product, we got actually a major, I should say, 3 major categories. Let me clear that one is the demising process, we call ECP MAP. And the second one, we call ECP TSV, right major for the TSV or TSV 3D. Number three is actually our advanced packaging tool, which we deliver for their packaging, and peeler or other advanced package requirements. Number four, we come with actually another copper plating and for the compound semiconductors, relatively small size, 6-inch and mostly eventually expand 8-inch. So with that products the floor is expanding. This year, we see quite a bit of a shipment and to the new customer. We are looking for actually probably 20-plus total tool will deliver total again this year. And some of them are recurring revenue. But most of them, I mean, as you say, it's hard to tell you right now, but some of them will be difficult to next year. But again, obviously, next year will become a repeat order, and then that will be real other bigger revenue boost or revenue, I call the product and to our portfolio next year.

So it sounds like if you've got 20 million-plus of tools delivered this year, repeat orders...

No, 20 -- I'm sorry, not 20 million, 22 number not 20 million.

Wow. Okay. Got it.

Yes. That's a lot of number, right? You know that in itself. That's right.

Yes. Got it. So we can definitely get to 10% of revenue pretty quickly. Got it. And then Mark, just your thoughts on OpEx. I know you guys are increasing the R&D to invest in all the new products. But as we look at the quarterly progression of OpEx, can you give us any sense as to what kind of increases you might expect into Q3 and thoughts whether OpEx would increase further in Q4, whether it would fall -- follow normal seasonality and maybe tick down a little bit in the fourth quarter?

Yes. I mean we don't give a lot of detail on our OpEx. We tend to guide on the top line. But for the year, we think the OpEx would be 28%, 29% of sales kind of a good mix of R&D that we talked about sales and marketing and then followed by G&A.

So yes, you don't expect any kind of significant changes in the back half of the year. But -- so you should get a little leverage in the back half of the year on the overall revenue growth.

Our next question comes from the line of Krish Sankar from Cowen.

I had 2 of them. First one, David, on the Bevel Etch using wet chemistry, who are the main competitors? Because it seems like most of them use dry. So I'm just trying to figure out who the comps are on the Bevel Etch process? And then I have a follow-up.

Great. Actually, like you said, I mean, I should say, in last probably 1 year, right, a lot of Bevel Etch is by the dry etch process, which is, I should say, it's pretty good performance. However, still you have other than particle remaining I call, etch splits, right? And then for that fortune, how to really got to clean again. But the wet process etch, I call it, etching tool, you are just wet edge process, making a much better profile and also give you a clean etcher without almost no particle on top. So that's really helping reduce the film -- the particle contamination and edge to the -- etch buy.

For our case, actually also innovative method, as I mentioned, we have a very precise alignment to control the center or to test the center wafer. And so therefore, we can reach much better centering performance, therefore, reaching much better control for the Bevel accuracy were leading to the better yield, right? That's our product.

Got it. Got it. Very helpful. And then just a follow-up on electroplating. Thanks for the color on the different drivers for electroplating. I'm just kind of curious David, you mentioned the electroplating market could triple to $1.5 billion in the next few years. I understand the different drivers like copper dual, furnacing and compound semi, but it almost seems like for the last few decades, this market is under $0.5 billion. The throughputs are pretty hard, the ASPs are pretty low. So I'm kind of curious what gets you to a tripling in market price to $1.5 billion? Is it just these 4 drivers you spoke about? Or is there anything else going on like ASP increases or throughput reduction happening?

Yes. Okay. Great. I think the major driving force is still from, I should say, probably Tier 3 and also the 3D packaging, right? Obviously, furnacing process has been like it is very stable. Obviously, the more volume, more wafer people talk about, that's a continued grade increase.

I think more of the driving we see here is like all the 3D packaging. Now they're talking about peeler from to improve 200 microns, mega peeler. With this kind of a higher peeler, you need more of a passive time into placing such a thicker peeler, right? So also, they talk about 2.5D and 3D. So there's a much more 3D application come out and for the packaging. Obviously, not only for front advanced, I call, application, even people today consider even 28 nano or even 40 nano, they are trying to combine with the advanced packaging technology. Then further enhance the performance. So with that in mind, we think this market continue to grow, right? And people project this year probably reach 700 million as a total on furnacing and packaging altogether. So we are very see that growing opportunity. And again, because driving by the post mortgage law, right? People focus on their on a lot of advanced package approach.

Our next question comes from the line of Charlie Chan from Morgan Stanley.

Great results. My first question is about the lead time between your shipment to the revenue. So maybe, Mark, can you please help me remind us what was the lead time?

Maybe I should take first, Mark? And at this moment, I should say, our average easy time around 6 months already, right? And again, average some specific product shorter, something may be longer. It's about 2 months longer than our previous 4 months' time. So that's how is it now.

Hopefully, as time going on, we can shorten that product cycle. At this moment, still, I should say, supplying a certain leading -- a long-leading item take a much longer time to get in hand. That's the major reason.

Okay. Yes, because I asked this because you talked about your annualized production, right? So if I look at second quarter, your shipment is above USD 80 million. And the full year production is exactly USD 350 million. So I'm thinking that when you try to expand your annualized production to USD 500 million. My question is that when will company's revenue scale will hit USD 500 million?

Well, the tough question. Again, right, I mean, shipment number, we normally do not the real quarter final release in almost end of the year, right? So only I can tell you this year, our shipment is much, much higher than last year. And actually number, I just say I might be waiting for our Q4 early release. But then as I mentioned [$5 million] revenue or shipment, right, be careful. So if it's a shipment probably easy to reach, right, hopefully, within next year. But revenue-wise, we're still based on what do you say, a lot of the new products and new customers are recognition big time, right? So again, I can see that a lot of shipments going on, but revenue-wise, we'll give you probably by early next year, then we see more visibility, what is our sales order next year.

We have our next question comes from the line of Donnie Teng from Nomura Securities.

My question is really related to your customers, right? So I -- in your prepared remarks, you mentioned about that you recently received new orders from -- for several tools from SMIC for the second half of the year, right? So I'm just wondering is there any approval granted by SMIC U.S. suppliers so that they can start to procure more equipment from our -- from ACM Research as well? Or is there any other reason behind? And for another customer like 1TC, right? So I think 1TC is running out of its Phase 1 capacity expansion maybe by end of this year or maybe sometime next year. So just wondering if you could kind of give us some update on maybe when will 1TC start a potential Phase 2 capacity expansion? So this is my first question.

Okay. Okay. Well, again, regarding licensing, there's a lot of different information flow in the market, right? And we do see some -- anyway, our same player in the industry, they said they got a license with for the entire tool or for the big tool. And also, we heard is some even component supplier, they also get their license too, right, a couple maybe 4-year onetime license.

So again, we see that, I call that a tension get released. But again, I don't know all this total product and SMIC is going to buy how much percentage get how much is not yet. So that information, I really cannot comment. That as I heard so far as I see. But however, we do have indication and they're trying to expansion, their demand, their customer, they really demand their capacity, right? So next year, they do have an expanding plan go into next year for SMIC, right? So we'll see probably as a timing go reach this year and also mid-Q3, we can see more clear picture on that.

Regarding 1TC, as we know, their Phase 1 factory, almost a floor occupied, right, and by capacity. And probably end of this year that the first Phase 2 Wuhan fab is going fully loaded. Then if we look in that building, right, I can only say what I say here, right, what is confidential. So if you look at outside the building, they building the next one, that in the process. So by that second building right now, we probably can say by end of this year, they can finish that construction. And then again, we're as a major supplier, we're expecting uptick finish construction, they should expand in their second fab.

Recently, I heard that they will make a successful 128-layer manufacturing, right? So with that, the technology be developed, it's very natural thinking that to continue expanding their 128-layer mass production. And obviously, this is a racing game. We're also expecting that going to even 198 or even more of layer R&D for the coming year.

So 1TC is a very good customer for us, and we have a very good relation. And also, we are expanding our product portfolio, right, not just only cleaning product, and we're expanding also other like copper plating and also other furnace products, eventually getting to the 1TC, also all the new advanced requirements, especially for the 225 layer and above. We're doing very good, I call it, planning to improving all products we have today to make sure we can meet the requirements, right, 2 years, 3 years from now, probably not tieing to any layer even more. So we are working very close and to joint develop our new products to meet their future requirements.

David, I have 1 follow-up on SMIC. So when you say that you receive new orders from SMIC, is that for like the Shanghai fab, the most attention high fab or it's for like Beijing, more mature nodes like above 28-nanometer?

Yes, we got actually from Beijing, their mature nodes. And also, I say that the expansion, as I mentioned, right, they compile also Beijing most happen, maybe Zhangjiang, right? That's what we're hearing so far.

Okay. And my second question is probably for maybe longer-term business expansion, right? So I think based on your sales scale, right. If we consider you have maybe like 80% of sales roughly from wafer cleaning tools, then I guess it probably will translate into like at least more than 10% of the market share in China already in terms of wafer cleaning tool. So I think probably you are the biggest -- already the biggest one and continue expanding market share in China domestically. But I think that kind of market share has been pretty high, right?

So inevitable, you need to expand to more new product portfolio, as you just mentioned, like ECP advanced packaging, et cetera. But on the other hand, previously that you are also trying to penetrating into overseas leading semiconductor customers. So I'm just wondering which targets are the priority right now? And could you kindly give us some update on your expansion in the overseas market?

Great. Great. Okay. I should say both important, right? Both market in China is important and also outside China is important. And actually, our long-term goal, let me give the long-term goal, we are trying to make our revenue 50% come from China market and 50% from outside China market, right? And that's why we're actually hire a building a strong team in the U.S. to approaching a leading customer U.S., also enhance our team in Taiwan too, right? And plus recently also we have further enhanced our sales team in Europe.

We believe our core, our proprietary technology like SAPS and TEBO for 3D cleaning without damaging and also Tahoe product with our, I call it, like a saving process. And also and we actually see that we also add additional new function, new requirements and further strengthening our cleaning products, right, in the advanced nodes, too.

So with all the innovation in the hand, we're trying to first demonstrate probably in the China and the Korean market. And we believe our product will eventually all major customers in the world. Every key customer, they need a best technology, right?

As I said, again, our proprietary technology and is a real unique approach we're providing. And with all the benefit, we think our differential product will get into the market outside China, right? And we are very confident, and we see that as a big movement and also building as for the time in the U.S. So we definitely want to participate better in gross market in the U.S. And also, obviously, you can see the growing market in Taiwan. And also -- and the potential maybe something happening in Europe, right, that people talk about the 2. So as ACM today, really were, again, equal important even revenue may do come from Mainland, China right now. However, we do see our future growth and also will come from outside China.

I have a follow-up, right? So -- because previously, impression is like you put more focus on expanding overseas customers. But in past few quarters, it's like -- it looks like our new products or our new equipment expansion to be faster than expected. So we put more emphasis there. I'm just wondering, is this kind of situation a correct -- right way to say or does that mean that we -- our schedule qualification schedule with overseas customers continuing to be postponed?

Well, again, right, I'd say we're working closely, right? Again, because now -- I should -- not a final material yet. But again, I think we are making progress, right? And when the time and reaching then we're going to announce that. But this moment I said that we're very working closely with the customer.

(Operator Instructions) Our next question comes from the line of Charlie Chen from Credit Suisse.

Okay. So David, you give a strong color on SMIC and YMTC. Can you talk a little bit about CXMT because I'm just curious that as they have been doing pretty well with all the other major guys in China. It seems that business is a little bit lower with CXMT?

Yes. Actually, we do see that business pick up, right? And probably you'll see it in 2 locations, one in Beijing, one in the Huali, right. And again, we are working close with them I will see that some, I call, order were already receiving and from Beijing new factory too. I know they have a bigger 40,000 expansion, right? And that will keep going and the partial release that order, we'll say probably most of what happened next year. but there continue improving the technology and improving the capacity.

So we'll see, right? And where we're working very close with them too. Our cleaning product and also copper plating and also further try to work with them together, expanding our furnace product, right, getting to their production line to for their evaluation.

So it's good for customer, and we hopefully, eventually, they become a top customer for us and in the coming years soon, right? So that's our effort to put here to win the customer at CXMT.

Our next question comes from the line of Suji Desilva from ROTH Capital.

Congrats on the progress here. On the global customer, I know you said you're going to ship in calendar year '21. And since you have 6-month lease, I guess, you have the visibility there. Just trying to understand if this is a production volume or pilot volume, is it SAPS, TEBO or back end, advanced trailing node, those kind of -- that kind of color would help.

Well, and I really couldn't release any product, right? Obviously, and via control, even if there's not a lot, I talked about which product they're buying. Anyway, we're not going to say that product is cleaning tool. And that it will be the evaluation tool. And hopefully, at the end of the repeat order deal and the typical process.

First of all, the valuation, even liking the type of product, they get all the production verification then we'll hopefully get to get order, right? So anything we'll repeat what that's going to happen next year, right? That's all we're expecting. Again, it's a good opportunity. That's why we're doing very good effort and make our team really sales and also servicing and all other related logistic supporting, right, for those happen.

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

Could you give us some color on your Asia. You said, you're just going to take another 1 to 2 months? So can you share what kind of process you are left with the CSRC? What's going to take for the IPO to go here?

Okay. Good. So Chi, actually, as I mentioned, on June 10, right, with actually the SSEC, right, Shanghai Stock Exchanging, based on meet the application right to the CSRC. So we're going through a question-and-answer. Actually, so far, the question give us they are all answered already, right? And now I've been probably in their internal procedure process and to get a final approve. And also just 2 days ago, we also submitted Q2 financial review, right, and to the CSRC also.

So we'll see maybe they come to -- some questions come back to our Q2 data. And anyway, we're prepared for that. Again, ACM probably is the first U.S. company has a headquarter in the U.S. They also have another IPO, with their subsidiary in Shanghai and apply for a market IPO, right? I'm pretty sure this is a really unique and first case. So it's reasonable, right? They take more time to consider and take more of cautious effort, especially we have this, I call it, short survey report to come out, right, all things put together.

Anyway, we have confidence. As I said, we're a good housing company and good technology and with our strategy. And I think we should be overcome in this, I call, the event when you get IPO in STAR Market. So I believe this will both really benefit our real ramp, our expansion plan in China and that's where we're believing what they're win-win, right, for the customer in China and our financial investor in the U.S. and also ACM global growth. So it's a good thing to try to work out and make it happen.

My second question is regarding your R&D expense. I think you have a very big job on your first half R&D expense. I think that's very positive, given you are expanding your product portfolio. But can you give us some color on the long-term R&D expense? Or will it stay, let's say, like high mid-teens going to next 2, 3 years?

Yes. Good question. Actually, let me put this way, as I mean a couple of earnings call and previous time, we want to balance, right, and profitability and also growth opportunities, right? So I think probably last 2 years, you can see of about 10%, 11% R&D. And this quarter, we get into the 14%, right?

So I think probably 15% is a good range for us to stay, right? Why it had -- and this gross margin, 40%, 45%, this is all operations coming together. You have to gather 10%-plus, right? That's kind of a profit reason. So we've got a values in the hand, and that probably give you 50% is probably a number we try to be keeping for the next 2, 3 years.

But let me add another difference were for other big guys, we spend the R&D money very efficient, right? Looking in the last 2, 3 years, we're developing copper plating and we divide the furnace. We spend also semi-critical in the cleaning process, also by end of this year, we're putting additional new cleaning function, other, even dry technology come out and with our cleaning product. We are spending very efficient money. We spend every penny and dollar and to maximize our R&D effort.

So I think 50% is a good number, and we can -- we've got a spending -- we have confidence we're getting to our new product come out on time line. And also, I think our key for our success or R&D is we always get an innovation product, right, always, I got the attention. We don't want again meet to him, that's number one.

Number two, we also have a very good team and working in Shanghai and working with the Korean market and Korean site. So that really gives us a strong R&D effort and then really either our product in the market. That's really -- I mean, historically we can see that. So with continued innovation, we are very confident, right? We'll continue pushing R&D at the next level with the new innovation product come up.

Your next question comes from the line of Christian Schwab from Craig-Hallum Capital.

Great quarter. I tried to sneak in 2 quick questions. I'll just ask them quick. Recent news about a leading customers bond default, would that -- is that potentially going to have any impact on you? Is question one. Question two is, what happens if YMTC gets put on the entity list? Is there any way to shift to them?

Mark, you want to answer that? Or I?

Yes, I can start, and then if you finish. But yes, the first one on the bond defaults, David's talked about that on prior calls. We're pretty confident that the operations of that customer are solid. And our general thought is that financing will be available hopefully from -- so long as the operation continues to execute that they can seek funding from other areas. And it's more of about ownership issue rather than a funding operation issue.

In terms of the entity list, it's -- they're an important -- YMTC is an important customer. I think David talked about, we expect growth, but likely a lower percentage. We're monitoring closely, and hopefully, they don't get put on the entity list. We feel pretty confident given our manufacturing operation in Shanghai and a lot of our technology came from there, that we might have some more flexibility to shift to -- should they get put on the list.

But of course, it is dependent upon their ability for the other suppliers to get licenses. So we'll monitor it closely, and we'll update if necessary.

That wraps up our Q&A session. I'll turn it back the call over to Gary.
