Good afternoon. My name is Britney, and I will be your conference operator today. At this time, I would like to welcome everyone to the KLA Corporation June Quarter 2021 Earnings Conference Call and Webcast. All participant lines have been placed in a listen-only mode to prevent any background noise. After the speaker's remarks, there will be a question-and-answer session. [Operator Instructions] Thank you. I will now turn the call over to Kevin Kessel, Vice President of Investor Relations. Please go ahead.

Thank you. And welcome to KLA's fiscal Q4 2021 quarterly earnings call to discuss the results of the June quarter and the outlook for the September quarter. With me on today's call is Rick Wallace, our Chief Executive Officer; and Bren Higgins, our Chief Financial Officer. During this call, we will discuss quarterly results for the period ended June 30, 2021. Released this afternoon after market close, you can find the press release, shareholder letter, slide deck, and infographic on the KLA IR section of our website. Today's discussion is presented on a non-GAAP financial basis unless otherwise specified, and whenever we make references to a year, we are referring to calendar years. A detailed reconciliation of GAAP to non-GAAP results is in the earnings materials posted on our website. Our IR website also contains future investor events, as well as presentations, corporate governance information, and links to our SEC filings, including our most recent annual report and quarterly reports on Forms 10-K and 10-Q. Our comments today are subject to risks and uncertainties reflected in the risk factor disclosure in our SEC filings. Any forward-looking statements, including those we make on the call today, are subject to those risks and KLA cannot guarantee those forward-looking statements will come true. Our actual results may differ significantly from those projected in our forward-looking statements. Let me now turn the call over to our Chief Executive Officer, Rick Wallace. Rick?

Hello, and thank you for joining us today. The June 2021 quarter showed continued momentum and strength for KLA. We delivered on our top and bottom-line goals and progressed against our long-term strategic objectives. Specifically, quarterly revenue grew 7% sequentially and 32% year-over-year to $1.95 billion. Non-GAAP earnings per share was $4.43, representing 15% sequential growth and 63% growth compared to the prior year. These results demonstrate strong growth momentum in our core markets and the operating leverage in the KLA model. We continue to see increased customer demand across each of our major product groups. This demand is related to ongoing secular demand trends, driving semiconductor industry growth across a broad range of markets and applications. Our customers are increasing their strategic CapEx investments to address these growth markets and investing in their leading-edge R&D efforts. Against the strong demand backdrop, we are navigating evolving customer needs and persistent supply chain challenges. Still, KLA continues to outperform expectations by operating the purpose and precision, and focusing on creating value for our customers, partners, and shareholders. This strong execution is led by our talented global teams, continuing to go above and beyond, constantly rising to the challenge and opportunities of the marketplace. I will quickly summarize our view of the industry demand environment. We're in a great position relative to growth drivers that are creating momentum for the industry and our business. As a result, our outlook for the wafer fab equipment industry continues to move higher. We have increased our growth estimate from low to mid-20s stated last quarter to the low to mid-30s on a percentage basis. This is from a base of approximately $61 billion in calendar 2020. With strong secular semiconductor demand trends continuing, we expect positive industry dynamics to sustain into calendar 2022. As our…

Thank you, Rick. KLA's June quarter '21 results highlight the soundness and strength of our ongoing strategies. We continue to demonstrate our ability to meet customer needs in a robust demand environment while expanding market leadership, growing operating profits, generating strong free cash flow, and maintaining our long-term strategy of productive capital allocation. Total revenue in the June quarter was $1.93 billion towards the top end of the guided range. Non-GAAP gross margin was 62%, at the midpoint of the guided range for the quarter of 61% to 63%. Non-GAAP EPS was $4.43, above the guided range of $3.47 to $4.35. GAAP EPS was $4.10. Non-GAAP total operating expenses were $419 million, about $7 million higher than expected primarily due to engineering materials timing and adjustments to variable compensation programs. Non-GAAP operating expenses included $241 million of R&D expense and $178 million of SG&A. At KLA, technical application support for our customers is included in SG&A was $44 million in the quarter. The combination of R&D expense and technical applications represents about 70% of total operating expenses. KLA innovation is fundamental to our go-to-market strategy focused on differentiated solutions. R&D is at the heart of KLA remains a key element in driving our portfolio strategy and product differentiation. This in turn help sustain our technology and market leadership. Non-GAAP operating income was very strong at 40%. Given higher revenue expectations for the second half of '21, product development requirements, ongoing regionalization of additional customer engagement resources, and increased investment in our global infrastructure due to overall business volume, we expect non-GAAP operating expenses to be approximately $430 million in the September quarter. Going forward, we will continue to size the company based on our target operating model which delivers 40% to 50% incremental operating margin leverage on revenue growth over…

Thanks, Bren. Britney, can you please queue up for questions?

[Operator Instructions] And we will take our first question from Harlan Sur with JPMorgan. Your line is now open.

Hi, good afternoon and great job on the quarterly execution and strong results. EUV adoption continues strong. And if I look at the outlook for EUV Litho systems expected to grow like mid-30% this year. Do you have a positive exposure here via your wafer inspection systems, but also the strong leadership in EUV mask inspection and printed. I know this doesn't represent your entire process control business, but it's sort of a good proxy. But you guys are guiding your optical inspection, your mask inspection, and your overall process control business to go well above that range. So, what are the two or three dynamics that are driving the strength above EUV adoption? And more importantly, with the visibility that you guys have, how are you feeling about the sustainability of the overall second-half momentum into the first half of next calendar year?

Hey Harlan, it's Rick. Thanks for the question. You're right. I think we are seeing a lot of strength in the process control portfolio driven. As I mentioned in the prepared remarks, we look at optical wafer inspection and really seeing a lot of uptake on that. What's interesting about that is, it's a pretty good mix between Gen 4 and Gen 5. So, both of the -- Gen 5 is more exposed, I would say to the EUV dynamic, but we're seeing more proliferation of Gen 4 also as people continue to add advanced capability. And we expected that with the rising complexity really across the board, and it's not just in the EUV areas of memory, logic, foundry, but also we're seeing it in memory; that's one area. We mentioned also reticles having a really strong year as the number of advanced designs continue. So, we're seeing both related to EUV, but also just increased process control intensity really across the entire portfolio. That's why we feel so strongly about the remainder of the year. And as Bren indicated, we're looking into 2022 for that strength to continue. Bren, you want to provide more color?

Yes. So, as Rick said, I think as we continue through the second half of this year, both those businesses are growing faster than market as we said in the prepared remarks. In fact, I would think that the optical inspection business is one of the fastest-growing markets in all of WFE, if not the fastest. So, there's a lot of inflections around EUV, but also other process dynamics that are driving that. But the introduction of EUV driving shrinks in the business or shrinks in design rules is creating an opportunity for both platforms and also leveraging optical inspection for validating reticle quality. Also 5-nanometer in the reticle part of the business, you also have increasing reticle complexity. And our offering in that market after a number of years where reticle complexity wasn't changed all that much in the double patterning environment. As we move to EUV, reticle complexity is changing dramatically. And our offering is a more technical offering and we're getting strong customer interest in that product. So, I think there's sustainable tailwinds here through the rest of this year and as we move into '22.

I appreciate that. And then on the gross margin front, if you could just help us understand the upticking in our gross margins into the September quarter. It looks like component costs are rising, I'm assuming the team also has to pay expedite fees for some parts and your end market mix is more weighted towards memory, which I would think would have some slight negative bias on gross margins. So, it's great to see the team driving the margin profile higher, but just help us understand some of the drivers of that?

Customer mix doesn't impact our margin profile, our products across all segments have the same margin profile. So, it really is a mix dynamic that is driving the quarter-to-quarter, 50 basis point increase we have. Most of the growth quarter-to-quarter is coming from semi-process control systems and those carry higher margins than obviously our service business or EPC business. So, that's been the bigger driver. We have supply chain challenges like everybody else and we're constantly trying to manage our way through those. Freight costs are higher, those are embedded. And maybe over time as some of those pressures alleviate, we'll get a little bit of benefit from that into the future. But we certainly have that in our numbers and expecting it to remain at that level over the next couple of quarters. On the component side, there is pressure on components, there is pressure on raw materials for frames and steel specifically, for the frames of our tools. So, we're dealing with that. Labor pressures are different around the world, we have factories in different locations but we're also dealing with that as well. I would expect as we move forward, we'll see some pressure. So, far it's been offset by the strength of the volume. So, we worked with our suppliers and the volume upside has been favorable. But I do expect we'll see some pressure on components. The way we price products tends to be value-centric. We have a value pricing model, not a cost-based model. But we're certainly going to have to deal with that as it comes through. With these revenue levels into the future, I would think we're probably looking at 10 to 20 basis points type of impact over time from some of the inflationary pressures on our COGS. But that's contemplated in the guidance we provided in terms of our margin expectations moving forward.

Great insights. Thank you.

And we will take our next question from John Pitzer with Credit Suisse. Your line is now open.

Yes. Thanks, Rick, Bren. Congratulation on the strong quarter. Thanks for letting me ask the question. Rick, I wanted to go back to your prepared comments about the investments that you're making in AI and ML. I mean clearly, some of your peers have talked about big investments in that area. I'd be curious if you can help us understand how you think you might differ from theirs? How -- maybe your incompetency [ph] gives you an upper hand here. And as you think about this, is this a way to maintain already outstanding share? Or do you think there is actually incremental revenue and SAM capability as you bring this out? And Bren, maybe on the gross margin; what could be the influence to gross margin? I'm assuming this is mainly software IP, which -- would it seem to be gross margin accretive?

John, thanks for the question. We've been working on what has been -- what is now called AI and ML for years now. And of course, because we handle so much data in our systems, especially in optical wafer system but also in the reticle system, that we've been having to manage that data and look for a signal in that data for a long time. What ML enables and machine learning enables along with AI is, just extracting more information out of that data. So, as we continue to have more capability to manage it, our work on AI has proliferated across most of our products now in some form or another but we continue to add upgrades. So, I think to answer your question, one way to think about it is we can squeeze more capability out of existing generations by leveraging the algorithms in the AI work. And in the past, where we may have needed to shift [ph] wavelengths for example to get more capability, we can do that with algorithm. So, one of the questions that had been brought up in the past was, for example, the limitations of optical wafer inspection and why EBM was going to maybe take a large prior of the share, that was the thesis a few years ago. But it was through AI and through ML and our advanced optics capability, that we've actually created additional node capability out of the optical systems. So, I think that's another way that we've expanded and lengthened the lifetime of the products, part of why Gen 4 has a longer life now is, we're squeezing more capability out of that, leveraging it. To answer your other question, it is expanding into our other products, those are the first really in the work we do at reticle. But it's also driving some opportunities for us in other segments as we expand the leverage of that capability into both metrology but also some of our traditionally lower-end wafer inspection systems that are applying and trailing edge capability [ph]. So, it's really kind of across the board. And you're right, it's very -- if you can amortize the engineering the way we do, it's pretty accretive to the overall business volume, because you're -- we do make a large investment. We're by far -- we have the most investment going on, no question among our peers because we're doing it across such a broad portfolio. But we're getting leverage as we have multiple products that are leveraging it. So, Bren can speak to how that drives the P&L.

Yes, John. And I think it's much more of an operating margin statement or a reduction in R&D intensity is another way to about it. Platform extendability is one of the biggest decisions we make in our product lifecycle processes. We're making choices and we can extend platforms. It means that over time we get a higher return on investment on those engineering dollars. So we don't have to go develop the next one, which is what drives significant cost of the model as you're developing and bringing a new product to market. So, by extending it, we see the leverage in our operating margins. Now, in terms of gross margin, software content or software offerings are increasing across the whole company not just within semi-process control, where we have businesses. Now that are starting to get to meaningful revenue levels, but we're selling software directly and we have that there, and we also have it in the EPC business where we're providing simulation capabilities, data analytics, other computational methods, design-based capabilities to help point our inspectors and get more value out of the KLA offerings. So, there is a few dynamics that are there that I think are good for us in terms of solving some of these problems as technology roadmaps get more and more complicated, but then also driving operating margin leverage over time.

Thank you very much.

Thanks, John.

And we will take our next question from CJ Muse with Evercore. Your line is now open.

Yes, good afternoon. Thanks for taking the question. As you think about your implied revenue guide for December, it looks like it's about $250 million of process control. And it sounds like that is coming on, based on new manufacturing capabilities that you're bringing online. So curious, what's the impact to gross margins at that time frame? And will that satisfy all pent-up demand? Or will your lead times still be extended heading into calendar '22?

Yes, CJ. It's a great question. As far as lead times go, I think lead times are holding pretty flat. One of the challenges and we had hoped that we'd start to see those pull in a bit, but demand has continued to increase. So we're seeing stronger demand and we're doing a lot of work to add capacity, so things are extending out, but they're not necessarily pulling in either. Yes, based on our comments, you do have a ramp in our -- in semi-process control equipment into the December quarter, that's a richer mix. So, I'm not going to guide December but that should carry a richer gross margin profile, given the nature of the products that we're shipping. That capacity has come online, that's a revenue recognition dynamics related to new facilities and product transitions that's pushing some of those shipments if you will that are happening this quarter that will happen next quarter. So, that's also part of the higher sequential growth that we're seeing into the December quarter. Did I answer your questions?

Yes, that's great. If I could just sneak a second one in. As you think about your foundry logic outlook for 2022 and you talked about continued strength, I was hoping you could speak to perhaps any changes that you see in the landscape whether leading-edge, lagging-edge, EUV adoption, DRAM anything we should be thinking about portfolio wise that could be a little different than 2021?

Yes. Really, I think just in terms of overall sustainability, we would expect to see the leading edge continue to invest as we go into next year. And given the public statements that have been made there, I think that's pretty consistent with what we're seeing. On the trailing edge side, we are seeing orders that are coming into backlog, but also in the funnel from a number of customers and much more meaningful levels of customers that haven't invested all that much in the past and are addressing some of these automotive and industrial, and some of these other more trailing edge challenges. So, I would think from a shipment and revenue point of view, we'll see that business actually start to come to the P&L as we move into 2022. China has been mostly logic-centric this year, native China. And so, I think we'll have to see how that plays out as we move into next year in terms of growth. Certainly, there is -- I think sustainability with the business levels that have been elevating through this year but I would expect to see a little bit more memory activity probably next year in China. And I think that's probably the one area we don't have as much visibility in terms of logic growth there. So, I think those are the dynamics and how they're planned. I think in terms of DRAM and NAND, I would expect those to continue to maintain the momentum that we've been seeing through '21.

But CJ, I mean, just one thing to add, a lot of the business that we're booking now is revenue in '22. I mean that's part of our confidence in '22. We're filled out for '21. And so, that's part of what we're seeing. And then some of the players you know who are trying to regain the lead, a lot of that investment hasn't really shown up in our revenue numbers yet.

Very helpful. Thank you.

And we will take our next question from Krish Sankar with Cowen & Company. Your line is now open.

Hi, thanks for taking my question and congrats on the strong results. I had two of them. First one for Rick or Bren. I do want to have the December quarter question a different way, you said your semi-process control should grow 40% this year, and a half or half is mid-teens growth. So, if I look at that, it looks like December quarter is around $2.3 billion, give or take. Is that a decent proxy for December revenues? And are you not seeing any impact from any of the component shortages that's affecting some of your friends in the industry? And then I had a follow-up.

Yes. So I'm not going to guide December specifically. What we're trying to do is give you some perspective on our expectations for growth of semiconductor process control equipment for the year, that was the high '30s to low 40 statement. We also talked about the total company growing mid-teens half to half, and so that was another statement there as well. So, I don't want to put a point out there in terms of the revenue guide but hopefully, you can get there with the details we have provided. Components are a daily challenge, we are managing across our factories, across our teams, managing our suppliers to be able to deliver the parts that we need. Some components have intrinsic lead times for us that are long term, and so, we have to make decisions and we've been making decisions to make investments or for that to make commitments to those suppliers to be able to provide that supply for us as we move into '22. So, it's a challenge, we're working our way through it. I'm spending more time -- I've been with KLA for 21 years and I'm spending more time on supply chain than I ever have. And certainly, as a CFO since 2013; so, we're dealing with it. We're making our way through it, and the guidance and context we provided contemplates what we expect to happen. It's our best expectations based on what we know today.

Got it. Thanks, Bren. And then, just as a follow-up, I do got a question on China. Obviously, you had really strong sales there in the June quarter. And if I try to back out, your ex-China sales had actually declined from March to June. And you also said China is mostly logic, so I'm kind of curious, are there that many logic foundry players in China? Or is this just a long tail of smaller players buying equipment? And any kind of color you can give on China with regards to your sales and any kind of split between domestic and MNCs would be very helpful. Thank you.

Yes. You have to remember that when we just talk about our mix of business that's the total company, so that includes EPC. So, I believe, our China percentage was like 32%. If you looked at the native investment as a percent of our semiconductor process control segment, it's about 25%. So, the numbers, when you're extrapolating like that can lead you to different conclusions. There are a number of small projects that are logic-centric projects in China that are targeting specific markets around IoT and image sensors, and a bunch of those kinds of opportunity is obviously, automotive and industrial. So, I think there are new projects in a lot of cases which are going to be coming online over time. But there is a lot of activity there. So, yes, there are.

Got it. Thank you very much.

And we will take our next question from Joseph Moore with Morgan Stanley. Your line is now open.

Great, thank you. I wonder if you could talk about -- you mentioned having new products for the automotive sector. And how are you thinking about this, you sort of see the older foundry nodes, looks like it's going to be a source of sustainable strength for a while. Can you actually target that business a little bit more directly than you have? And just generally, what kind of activity are you seeing in the older foundry nodes?

Yes. Sure, Joseph. We've actually been engaged for quite a while with some of the leading automotive -- even the automotive customers coming to us asking us to help them with their suppliers. That's been going on for a few years. What's really happened now is, it's broadened, the number of customers that are recognizing and of course the shortage of automotive semiconductors contributed to that. So, we've been developing products that have, I would say, are adaptations of existing products that provide additional capability in support of automotive, whereas you know, they're looking for more reliability, there is some cases where we're helping traceability in terms of how they're driving those fabs. So, yes, that's an area we outlined in our 2019 Analyst Day where we talked about, that was a growth area for us and we believe it continues to be. Obviously, it was a rough start to 2020 where a lot of customers shut down their plants for automotive semiconductor now to their dismay, but those are back on. And so, we do have those products, we're engaging with customers, and there is a strong demand for that, and we think that's sustainable and we think that will continue to grow as more of the automotive players see the value in that and that will just continue to broaden. So, we have a segment and a work area that we're focused on that and it's also where our business that we got through, Orbotech, SPTS works also some of the process capability there. So, it's more than just inspection, it's broader for us than that. So, it's pretty exciting. It's a good growth area and I think it's one that we'll continue to see progress over the next several quarters.

Thank you very much.

And we will take our next question from Joe Quatrochi with Wells Fargo. Your line is now open.

Yes, thanks for taking the question. Curious on your advanced packaging. You recently talked about packaging becoming more like front-end. I was curious you know, how would you compare maybe contrast the two in terms of just the increasing capital intensity. And then maybe can you touch on your position in front-end and how that maybe drive differentiation for the packaging?

Joe, I think there's a couple of things. One is, as more of the big players are focused on packaging as a source of either maintaining differentiation or closing a differentiation gap, there is more investment with larger players that know KLA. And frankly, I think we're getting more seats at the table and engagements with them because of their knowledge of KLA and their desire to put their best behind a proven player. So, we have the capability. We have some products. We're doing some product developments, some product adaptations in support of that, but the technology there is moving. The process control intensity is significantly lower than it is of course in the leading edge, but the rate of growth is very fast, the rate of growth of process control. So, I would say, we have an abundance of opportunities there to execute on, but it will require us to bring new capabilities. And so, we're engaging with our customers in that. And I can tell you, we're getting as much pool there as we are in the front end for capabilities as customers try to accelerate their roadmap. So, we're seeing strong growth as we increase the process control intensity and it's not just process control, once again some of the process equipment we have with SPTS is also being leveraged in that area as well as in our PCB business, which isn't all inspection and measurement. So, we do see strong growth. We see a lot of potential consistent with the plans we laid out in 2019 at our Investor Day.

You also have the integration of the PCB board to IC substrate into the package and so that's a good driver for us moving forward. We're working on new capability to better address that market. We also -- the ICOS' finished component inspection business is inspecting the packages, so that complexity is also driving an inflection in that market. We're seeing very strong growth in that market as well. Probably the fastest-growing part of EPC is today is through ICOS. So, I think there's a lot of opportunities as Rick said and some of it's dependent on us bringing new capability to market. But certainly, customers are trying to leverage the different positions we have across a number of different applications, trying to leverage the relationship with us to do more there.

Yes. And just to put a number on it, we said $400 million in 2019. We're ahead of plan and we can beat that, do more than that with some of the developments we're contemplating. So, I think we've got the products now to perform to that and we can do more. And we're getting encouraged by the signs that we're seeing and engaging with these customers.

Super helpful. Thank you.

We will take our next question from Patrick Ho with Stifel. Your line is now open.

Thank you very much and congrats on the nice quarter and outlook. Rick, maybe first off, big picture, kind of the long-term outlook for the process control industry and your positioning gate-all-around [ph] is becoming or it will be coming on board in the next few years. And I know you probably are working with your customers. You've got an incremental benefit when the industry transitions to FinFET transistors. How do you see the incremental opportunities as you go to gate-all-around where not only are you seeing new materials but more materials in that transistor area.

Yes, it's a great question. And as you know, with all our business, any of these technology transitions, inflections present opportunity for process control, because the first thing that our customers need to figure out is how to get the process ramped. So, I think we're seeing advanced indicators that that's going to be great for adoption of additional capability. It's also where the portfolio really matters, because in the case of gate-all-around, adaptation to the Gen 4 wafer inspection in some ways is more important than what Gen 5 does. Gen 5 is very important for the smaller defectivity that we need to detect and the lower rates but Gen 4 for the contrast. And so, some of the development we've been doing with our customers has been to tune our products for that advanced transistor capability. So, I think that what you'll see is a continued increase in process control intensity. The way we modeled it is relatively modest over the long term but of course, the cumulative effect is it adds up and that's why we think process control intensity outgrows WFE on the order of half a percentage point if we're going from 15 to 15.5 depending on what the aggregate, that's a blended between logic and memory. But we'll see it over time that you'll see it creep up as a result of those new inflections, provided we have the products to support it, which is a lot of the work that we've been doing. So, we feel like we're really good position to support our customers to do that.

Great, that's helpful. And my follow-up question may be for you, Bren, in terms of the investments you're making. We talked about systems, picking up expanding capacity, bringing people on board to meet the increased shipments. Services are also growing quite rapidly and you've mentioned that, it's growing faster than the target CAGR you are looking at. What are the types of investments you need to make in services given that not only is your semi services growing as the installed base grows, but PCB tends to be a very service-intensive business as well. And that marketplace is also showing signs of some more secular growth trend given some of the marketplaces that they penetrated. How do you look at service investments, both near term and over the next few years?

That's a great question. And certainly trying to get more leverage out of the service business is of the acquired companies. Acquired businesses for KLA has been one of our parts -- a key component of the investment thesis when we look at these kinds of transactions. And smaller companies have a hard time trying to have the infrastructure just given the nature of their size to be able to support a broad service footprint. So, being able to leverage our infrastructure now the go-to-market is different, how we engage with those customers is different. So, leveraging the infrastructure we have is I think a big part of that so there is a big cost element. We made the investments, I think we need to make. Certainly, China and the investments we made back in 2016 and 2017 to build infrastructure to support the China business is great for us now and we're seeing scale on that. With some of the regionalization dynamics that are out there, if we see new fabs popping up, we have to build that capability in some new places. We think those are great opportunities for us because our customers rely on us to help bring those kinds of facilities up and to bring our capability to help them do that. And so, whenever they're building a new fab in a new geography, it creates a big opportunity for KLA. We're working on remote diagnostics, remote capabilities, so we can do a lot more diagnostic, these diagnosis tool problems from back here from the factory or from our development teams depending on what's happening. One of the challenges in COVID obviously, has been getting people in and out when we have an escalation situation. So, I think those are the kinds of areas that we're investing and it's a great opportunity for us just in terms of growth given the strength of the WFE, but also the lengthening of lifetime on the tools and how customers are using them from a utilization point of view.

Yes. And then, the biggest investment really right now is in the workforce to support that. And so, as Bren mentioned, we're working on that. I think that hiring, training, on-boarding as we anticipate the continued growth is an area we've done well with. But as you know, there is a big demand for talent out there. So, we have to keep on it, keep hiring and doing that training. So, that's probably the biggest area of investment, over time that's going to be the workforce.

Great, thank you.

And we will take our next question from Timothy Arcuri with UBS. Your line is now open.

Hi, thanks. I had two clarifications, Bren. And then I had a real question. The first two clarifications are, the comment you made about 15% half-on-half, that was a corporate revenue comment. Somebody attach that to a process control systems, but I don't think -- I think your process control systems comment was up like mid-30, high-30s to 40% for the year. That half-on-half comment was a corporate revenue comment. Correct?

That's correct, yes. And I attempted to clarify that in one of the earlier questions. But yes, you're right. That's the total company aggregate revenue expectation second half versus first half, mid-teens.

Perfect. And then the second clarification, did you say that domestic China is 25% of your process control systems revenue. Because WFE, it's like 15% of total WFE.

In the quarter that we just completed.

Yes. Okay, got it. Okay. So for my real question, I guess. So I wanted to ask about actinic. And it's always really been Tier to high NA for EUV. Otherwise, you use the 8xx and now you have the big microprocessor maker that's now pushing more aggressively on high NA. So, are you going to accelerate your development timeline for actinic?

Yes. Tim, it's a great question. We feel confident that we will have the capability we need when it is needed for the high NA. So, I understand what your question is, we believe that with the products that we have, with the 8xx in particular, and actually the continued capability we're seeing in 6xx, we feel that we will be there when the market is needed for the high NA.

Hey, Tim, just to also clarify on the China statement. So, that's of the semiconductor process control segment, which includes the service. It was 25% of the revenue in the June quarter.

I see, including service. Okay, Bren. Thank you so much.

And we will take our next question from Vivek Arya with Bank of America. Your line is now open.

Thanks for taking my question. I'm curious if let's say hypothetically, WFE is 90 billion or 100 billion next year, are you prepared to support that right from your capacity perspective? Or I guess a different way of asking the question is, how much additional capacity are you planning to bring online next year?

Yes Vivek, that's an interesting question. And right now, what we're trying to do is ramp up to support the customer demand that we have. And I have expectations for incremental capacity as we move forward now. I feel like these are good investments to make for us over the long run given our expectations for multi-year growth in WFE. I think given the strength of the WFE investments in some of the end market drivers that we're talking about, that we would expect to see WFE grow over the next few years, at least in line with semiconductor revenue with rising capital intensity probably faster than that. So, these investments and given the extendability of our platforms and the lifetime of our tools in terms of how we're shipping to a very broad demand environment from a technology point of view, that these are investments that are important for us in terms of just being able to support that kind of environment moving forward sort of a through cycle over time statement. But we're continuing to invest to make sure that we have the flexibility to be able to respond to our customer demand. So, I think that's -- as I look at it right now in terms of the first half of the year, in terms of expectations, hard for me to see how -- it's at least as strong as what we've seen in the second half of '21 in terms of what we see in the funnel and in our backlog in terms of how we're managing it. I don't want to make any statements much beyond that.

I think the one thing I would add is, we are cognizant of our customers' desire to get more capability sooner and we're doing everything we can to size it. But the numbers you've talked about, we have contemplated in our plans.

Maybe a quick follow-up if I can. At what point do you sense that because of all the headlines around the capacity crunch, you have players who are now trying to become foundries on their own. That there is a pull-forward of demand that at what -- what's on your dashboard to tell you that whatever you're shipping right that the utilization levels are quite high and it's not just customers scrambling to add more capacity. Like, do you track what the usage is of the equipment that you ship?

Yes. Of course, we track the usage. I mean that's a metric that we're looking at all the time. But I would back up a little bit and say that the industry actually has a self-governing mechanism in it, which is the ability of all the equipment companies to ramp to the demand. And right now, when you talk to customers, they would take more shipments I think from everyone if they could get them sooner. So, there is a natural governance. And I'm sure you've heard, ASML talk about EUV through '22. So, it's naturally governed by that. So, I don't -- I think we're in a good place for a sustained run at this point.

Thanks for that. Britney, we have time, it looks like for one last question.

And we will take our final question from Sidney Ho with Deutsche Bank. Your line is now open.

Great. Thanks for taking my question. So, speaking of this multiyear investment plans that you just talked about, there -- obviously, there is a lot of new fabs being announced in the past few months. When do you expect those new fab investment to start generating revenue for you? And when do you expect to start seeing those orders coming in?

Well, in a lot of cases, we're already seeing the orders, right? So, I think that customers are getting into the queue for deliveries. And in some products, deliveries could be 12 months from now. So, it's absolutely happening and customers are trying to make those commitments as they're planning for their facilities. Obviously, they plan across a lot of different types of equipment. And so, those planning cycles tend to move around a little bit. Sometimes they are also dependent on winning business and product ramps and so on. So, there's always a little bit of variability around the timing. And then of course, generally as you try to build something, there's always infrastructure and delays and pull-ins that can happen associated with just construction overall. But yes, we're absolutely seeing that demand in the backlog and certainly in the sales funnel.

Okay, great. Maybe my follow-up; it's a lot of questions on the semi process control side but, on the EPC business, is 15% growth for this year still a realistic assumption given the strength in auto and 5G? And maybe you can talk about with or without the display side of things. Thanks.

Yes. Including display, we're in the high teens for that business. So, we're seeing strength there. Display is about as we expected and we're seeing strength, I mentioned earlier about component inspection. Especially, semiconductor is also seeing strength. PCB is ahead of plan a little bit so I think that's moving along. Obviously, it's very tied to mobility and 5G. So, yes, we're seeing that pick up in terms of expectations for growth out of that product group.

Okay, great. Thanks.

I would now like to turn the program back over to Kevin Kesseler -- Kessel, I apologize for any additional or closing remarks.

Thank you very much. And wanted to thank everybody for their time, their interest, and their questions. We will be in touch. Take care.
