Good day, and welcome to the Lam Research Corporation December Quarter 2019 Financial Results Conference Call. At this time, I would like to turn the conference over to Ms. Tina Correia, Corporate VP of Investor Relations. Ma’am, please begin.

Thank you and good afternoon, everyone. Welcome to the Lam Research quarterly earnings conference call. With me today are Tim Archer, President and Chief Executive Officer; and Doug Bettinger, Executive Vice President and Chief Financial Officer. During today's call, we will share our overview on the business environment and review our financial results for the December 2019 quarter and our outlook for the March 2020 quarter. The press release detailing our financial results was distributed a little after 1.00 PM Pacific Time this afternoon. The release can also be found on the Investor Relations section of the company's Web site along with the presentation slides that accompany today's call. Today's presentation and Q&A includes forward-looking statements that are subject to risks and uncertainties reflected in the Risk Factors disclosed in our SEC public filings. Please see accompanying slides in the presentation for additional information. Today's discussion of our financial results will be presented on a non-GAAP financial basis unless otherwise specified. A detailed reconciliation between GAAP and non-GAAP results can be found in today's earnings press release. This call is scheduled to last until 3.00 PM Pacific Time. A replay of this call will be available later this afternoon on our Web site. With that, I will hand the call over to Tim.

Thanks, Tina, and welcome everyone. In the December quarter, Lam delivered revenues and diluted earnings per share above the midpoint of guidance, marking another quarter of solid execution and closing out a year of strong performance in calendar 2019. Consistent with our comments throughout this year, we enter 2020 with increasing momentum and an improved spending mix environment which we believe will lead to outperformance by Lam. I have now completed my first year as CEO of Lam Research and I am incredibly proud of what our people have achieved. Underpinning our strong financial results this past year has been a companywide focus on execution and an emphasis on our culture where all employees can perform their best. I want to thank Lam's employees across our global organization for their efforts and of course our partners and customers for their valued support. I also want to take a moment to address the coronavirus situation. Our concern first and foremost is with the health and well being of our employees, customers and partners and with this in mind we have implemented precautionary measures within our global business operations. Additionally, we are donating to Chinese relief efforts to support the people and communities impacted by the coronavirus outbreak. Now turning to our business results. In calendar 2019, we generated solid operating cash flows and at the same time we invested a company record in research and development dollars to fuel technology innovation and product differentiation. Our EPS performance, the second best in the company's 40-year history, was especially noteworthy given that memory spending declined significantly year-over-year in 2019. The impact of lower memory spending was partially mitigated by record revenue from our customer support business group, highlighting the importance of our recurring spares and service opportunity to the overall quality of earnings…

Great. Thank you, Tim. Good afternoon, everyone, and thank you for joining us today in the middle of what I know is a very busy earnings season. We concluded calendar year 2019 with the strong December quarterly performance. Results ended up better than we expected, primarily due to a little bit stronger NAND investment as well as an uptick in our installed base business. Our installed base business delivered another record year and continued to be a stable profitable business for us. And as Tim mentioned, from and earnings per share perspective, it was the second best year in our 40-year history. The December quarter results came in over the midpoint of guidance for all financial metrics with diluted earnings per share essentially at the high end of our guidance range. As Tim also noted, we’re pleased with our performance in calendar year 2019 and we delivered solid profitability levels within a challenging memory environment. As we discussed at our earnings call last quarter, there were continued strong investments in the foundry and logic segments in the December quarter. We had the highest system revenue dollars for the foundry segment in our history and the revenue concentration was at its highest level since the September 2016 quarter. Foundry spending continued its focus on the 7 and 5 nanometer nodes and it represent 36% of our December quarter system revenue. The logic and other segment grew in dollar terms and was essentially flat with the prior quarter intensity level coming in at 12% of system revenues. It was the highest logic and other revenue level in dollar terms in two years driven by 10-nanometer, image sensors and other specialty markets. For memory, the combined segment decreased to 52% of system revenues from the September quarter which was at 64%. We had…

Yes, sir. [Operator Instructions]. And our first question will come from John Pitzer with Credit Suisse.

Good afternoon, guys. Thanks for letting me ask the question. My first question just is been focusing on the domestic China market. Doug, you were kind enough to tell us it was the majority of the China business in the December. I’m wondering if you can help us understand how much of a majority it was. And what was the split between sort of memory and logic? And then as you look out to your WFE forecast growth of at least 20% in calendar year '20, how important is the domestic China market and how should we think about the memory versus sort of the logic/foundry side of that?

Yes, I’ll answer it and then I’ll let Tim add on. John, I’m not going to get into the habit every quarter of giving a precise quantification except to tell you the majority in the December quarter was from domestic China. And that’s been the case the last couple of quarters. And the reason I’ve been mentioning that over the last couple of quarters is it’s different than the last several years have been where the majority has actually come from the global multinationals. Then your question relative to how we’re looking into 2020 in China, I think 2019 probably finished with WFE from the local China customers a little bit above $6 billion, something like that and it’s growing in 2020. And as we look into 2020, I think John probably it’s up $2 billion to $3 billion is my best guess from local China. And that spending is broad based; it’s NAND, it’s DRAM, it’s foundry and logic. So it’s not one or the other. It’s broad based settled [ph] for customer spending. Tim, you want to add anything.

No, I think that pretty much covers it.

And then as my follow on just on WFE and kind of your share, Tim, you talked about in your prepared comments you did a nice job kind of gaining your share of WFE. Is 2020 a year where that becomes a little bit more difficult with sort of the addition of EUV or how important is EUV to your growth projections this year? And as we think about EUV deployment, is that a good leading indicator for your future business or how should we think about that?

Yes, I think that – we’ve talked about EUV a number of times. And so I guess maybe I’ll just repeat a few things I said and maybe add a couple of comments. In general, what we’ve said is that technology transitions themselves are very good for Lam. We have highlighted a number of times that Lam’s served market actually grows at each technology node within foundry/logic even with the introduction of EUV. So really what we want is we want the market and our customers to be able to keep moving their technologies forward. Specific to patterning as you move from say 7 to 5 nanometer, even in the case of EUV what you’re starting to see is, is the increased use of more high-quality hard masks moving away from spin on dielectrics towards deposition metals like PECVD where Lam has a very strong position. And so in many cases, our SAM is actually increasing because we’re pulling in applications that before were actually done with older processes and now they’re coming into a more critical space. And so with that, we see SAM increase and therefore even with the EUV we see a growing market for ourselves. Doug talked about highest dollars from foundry and logic and that’s just I think further evidence, because we’re seeing technology investments right now at those EUV nodes. Now as far as the leading indicator, John, what we said is that EUV is obviously – those shipments are signs of these more complex technology nodes and again our SAM grows, so opportunity grows.

John, the only thing I would add, as you think about wallet share of WFE going into 2020, I think you know our SAM and share in NAND is very good. And clearly 2020 in our view is going to be a stronger investment period for the NAND industry as we’ve seen kind of pricing and profitability stabilize. So our share of wallet actually in addition to the EUV commentary Tim had is actually going to have a tailwind from the fact that NAND spending I think will be stronger.

That’s right.

Thanks, guys. Congratulations again.

Thanks, John.

All right. Thank you. Our next question comes from C.J. Muse with Evercore.

Yes. Good afternoon. Thank you for taking the question. I guess first question on WFE as you think about the roughly $8 billion to $10 billion increase year-on-year into 2020, can you tell us how much of that is memory versus foundry and logic? Is that kind of an 80/20 split? And then as part of that, are you including the material uplift in DRAM within that or is that something that could be a source of further upside?

Okay, C.J., great questions. I don’t think we’re going to give you the exact breakout, but I think we’ve characterized it as – maybe you can look back to what we said as we were exiting last year. What we said was that we were seeing very strong spending in foundry/logic and that we were just starting to see the early signs of improvement in NAND and we felt that DRAM would come after the NAND market had improved. And so I think what you’re seeing in our outlook for 2020 is that starting to play out. Except for again sustained strong spending in foundry and logic, certainly the emphasis on sustained and a strong uptick in NAND spending which as Doug just commented is a significant tailwind for us in terms of our SAM as a percent of WFE. Relative to DRAM, I think we characterized last year primarily as the technology investment year with very little capacity additions. And I would say that in general our outlook at this year is that that doesn’t change much at least until much later in the year. So I’d say primarily sustained strong foundry and logic and a strong uptick in NAND.

Great. And as a follow-up question on the service side, thank you for providing the installed base numbers, very helpful. So up I think 12% in calendar '18, up 9% in calendar '19. Can you help us kind of think about what the growth rate for service could look like? And is it fair to say that service in 2019 reached roughly mid-30s of total revenues? Thank you.

So I’ll take the last one. It wasn’t quite that high, C.J., but it was comfortably above 30 in 2019, I’ll give you that much.

I think that we’re very confident. We’ve said that because of the growing installed base, the overall customer support business grows every year. How it grows each year I’ve talked a little bit about that dynamic where depending on where you are in kind of utilization and spending and customers will spend on different things. I highlighted a very strong year for us in 2019 on productivity upgrades which is – one of the things customers do when they’re looking to squeeze a little bit more out of the assets they already have in their fabs and we saw a lot of that last year. I think that as you transition now to a very busy year and customers ramping aggressively, then you’ll find yourself much more in this comparison and some of the value-added services part. But in general, given the dynamics with our market and our product portfolio, we feel very confident about its ability to grow year-on-year with the installed base.

Thank you.

Thanks, C.J.

Thank you. Our next question comes from Harlan Sur with JPMorgan.

Good afternoon and great job on the solid business execution. With the complexity of the manufacturing process combined with higher specifications, maybe longer install and call times, on average from the time that you ship a tool to the time that that tool is put into full value production, I think greenfield is around six months. Is this lead time around the same time for conversion and incremental capacity expansion? And the reason why I ask is I just want to do a sanity check that for some of the memory shipment goodness that you’re seeing, hopefully this is going to be layering on in-sync with the demand pull for memory which is typically more kind of middle to kind of second half of the year weighted?

I don’t think we’ve really broken it out. In fact, I don’t know that I could even really speak to a material difference in lead times. I guess if I caught your question, it was does a conversion have approximately the same lead time for the upgrade to take place and the product to be called? If that was the question, I would say they’re not dramatically different in terms of cycle time.

Yes. And Harlan, maybe I’m guessing what your question might be. When we look at the way spending occurred in the second half of '19 in NAND, and I remind you we were saying this for a while. We exited the year we believe the industry’s supply growth 30% year-on-year. Based on the investments we saw occurring in the second half of '19, we believe that rate will decline – supply growth will decline into the first half of '20, right. And so you’re starting to see an uptick in investment that will have a lag effect to it and it won’t immediately be producing output. I think that’s inherently what you’re asking, right?

Exactly. That’s exactly right and I appreciate the response. And actually as a follow on to that, so you guys had anticipated NAND bit supply growth exiting 2019 around 30% below the demand rate. I think some of your customers in DRAM were seeing bit supply kind of low to mid teens again before kind of the demand rates. So given the improving fundamentals in memory this year, kind of extrapolating from your customer equipment requirements this year, how do you guys see bit supply growth in NAND and DRAM this year from kind of the depressed levels exiting last year?

Yes, so you got it exactly right what we said. We exited the year well below the long-term demand trend. And actually even with the guidance we’ve just given, we actually see ourselves under growing long-term demand this year in terms of bit supply growth both in NAND and in DRAM.

Great. Thank you.

Thanks, Harlan.

Thank you. Our next question will come from Atif Malik with Citi.

Hi. Thanks for taking my questions and a good job on results and guide. If I look at your top line growth historically, you outperformed WFE by 2x or so. How should we think about your top line growth relative to WFE for this year?

Atif, the color I’d give you is again what I’ve already said is I think it’s an uptick in NAND investment. Our SAM and NAND is really strong. Our share in NAND is really strong. And so to the extent that NAND is driving an uptick in WFE, Lam will do really well. And you’ve seen that over the years in times when memory is spending more, we do real well and when it’s going to other way, we do less well. You should expect the same thing. I’m not going to quantify it for you whether history is a good indicator, I’m not completely sure. But I’ll be very disappointed if we don’t outperform this year.

Very helpful, Doug. And as a follow up, your WFE number for this year is even bigger than what we were thinking 55 billion. Can you just talk about the opportunity in which sensor, advanced packaging, things like that and how big that number is in your WFE number for this year?

Yes, we’ve put that in the logic and other space. And what Doug indicated is we expect foundry and logic to grow '19 to '20. I don’t know the exact image sensor number, so I can’t answer your exact question. It’s a secular grower for sure. But in the grand scheme of how big foundry and logic is, it’s actually not all that big. But it is something we do really, really well in, in terms of the TSV aspect of image sensors.

Yes, all I would add is, is one of the reasons you’ve heard us talk a lot more about specialty technologies and some of the products that we introduced in 2019 really focusing on heterogeneous integration and advanced packaging and MRAM and the image sensors was because many of those items are somewhat growing year-by-year from applications that are a little bit decoupled from the larger WFE cycle. And so again even last year’s WFE was down, we were setting records in what we kind of prefer to as our specialty technologies business which is primarily served by the Reliant tools.

And so I think you can continue to see us focus in those areas because they’re places where our technology plays very well. And as Doug said, we can by bringing the right technology and cost point we can really gain quite a large portion of that market.

Thank you.

Thank you.

Thank you. Our next question will come from Vivek Arya with Bank of America Securities.

Thanks for taking my question and congratulations on the strong and consistent execution. I have two questions as well. The first one, I’m curious what goes into your WFE calculation just because it’s such a strong outlook for this year. Is it orders, is it CapEx, is it memory pricing assumption? I’m just curious what goes into it? And as part of that, if you could also give us some color on how you think the shape of WFE looks like first half versus second half?

Yes, I’ll go through it and then I’m sure Tim will have comments on that. We go at this in a couple different ways. We talk to customers first and foremost. Customers tell us here’s our plans, here’s what we think we’re going to do kind of customer-by-customer, fab-by-fab. So that’s the bottoms-up approach to it. It doesn’t mean it’s exactly precisely correct. It changes. Customers’ plans can change, but that’s one aspect of how we come at it. The second aspect is actually a tops-down approach, which is we take a read on, okay, what is global GDP going to look like this year? What does that mean for electronics demand? What does that mean for IC unit and semi revenue growth? And what does that mean relative to wafers and technology? And then we try to correlate the two approaches together. We don’t always get it perfect, but it’s a pretty robust process and I think we do a decent job. But we don’t always get it exactly right, but we do our best. Tim, anything?

Yes, I think it stems, as Doug said, from pretty extensive conversations with customers. One of the nice things about this business is that we have developed very deep relationships with customers and they’re just as interested in having us deliver the technology they need on time. And so I think it’s pretty open sharing about when tools are needed when the ramp is going to occur. So that factors quite a bit into the calculation.

And anything on first half versus second half?

Yes, I think that it’s going to be a little bit of a first half weighted year really driven by foundry and logic. I think memory spending is going to be pretty steady through the year, but I think foundry’s probably a little bit first half weighted.

All right. And for my follow up, your installed base has grown at a 10%, 11% annual base the last five years, which is pretty remarkable given the volatility in WFE. My question is how fast have your services kind of grown annually during those five years and how should we think about the installed base and services growth for the next two to three years? Thank you.

Yes, I’ll give you little color. The best indicator of how it’s growing is just chamber count, because that really is what drives the business opportunity. Having said that, we’re doing a lot of innovative things around advanced service offerings in different ways to deliver value to customers that drives our objective, Vivek, at the end of the day to have dollars grow faster than just the growth in chamber count. And if you come see us in March, we’ll probably give you a little more color around what this business looks like.

Yes. And I think the only thing I’d add, I made comments about the productivity upgrades and solutions a part of that business. It’s – obviously every customer is driving to reduce their running cost in their fabs. And so between upgrades for existing tools as well as new really data-enabled services that we offer to help recover tools more quickly with less labor and with a higher probability of first-time right. That part of the business is actually growing very fast and I think has the ability just as it did the past year of growing 30% year-on-year the ability to outgrow the installed base. And so we’re investing in that area.

Thanks very much.

Thanks, Vivek.

Thank you. Our next question will come from Krish Sankar with Cowen and Company.

Yes. Hi. Thanks for taking the question and congrats guys on the great results. Just two quick ones either Tim or Doug. When you look at the calendar year 2020 and like you mentioned WFE is probably front half loaded and mostly foundry/logic bias going towards memory in the back half. Are there any nuances in gross margin we should worry about or is there like one segment has a better gross margin profile than the other? And then I have a follow up.

No, there’s nothing specific to gross margin by segment that you should be thinking about. It varies with customer mix, it varies with product mix and then overall business volumes is what I think I’ve said every single quarter that I’ve been at the company, it’s the same language. So there isn’t anything specific by segment.

Got it, Doug. And then just a follow up on the OpEx. I understand March has the seasonality with all the merit increase, et cetera, but how do we think about OpEx on a go-forward basis? Is like 18% of sales a good bogey to use or is the 500 million plus run rate – quarterly run rate the right metric?

If you look at what we’ve done over the longer term, we’ve let spending grow at a rate less than the top line has grown over the last, I don’t know, since we brought the two companies together. And I think you’re going to see us thinking that same way as we see a stronger year in front of us. And again, come see us in March I’ve give you an updated financial model as well.

Got it. Thanks, Doug.

You’re welcome.

All right. Thank you. Next we have a question from Timothy Arcuri with UBS.

Thanks a lot. Doug, I had two. First of all, China has been running about 30% of revenue for the past three quarters. Should we expect it to be about 30% as a percent of revenue in March? And I assume within that that it would still be – like the vast majority of it would be the domestic guys. Is that correct?

Yes, I’m not going to get into kind of telling you quarter-by-quarter what it is, but I’ll remind you what I said earlier. I think it grows $2 billion to $3 billion of a base of 6-ish – going a little above 6 for the year. It will lumpy. Tim, you know how this goes. There’s a project that takes tools, then has to ramp it for a while and digest it, then something else kicks in. I’m not going to give you exact color around – on the March guide, but I think it will be a good year for local China this year.

Okay, great. Thanks, Doug. And then I guess this is kind of a bigger picture question, but given what’s going on with export control, you’re saying that domestic China is going to add maybe 2 billion to 3 billion to 2020 WFE. Do you think that there’s any of this incremental stuff going on within China where customers are concerned about maybe someday down the road they can’t get access to tools, and so maybe they’re calling in timelines of these fabs? Thanks.

Yes, I guess I’ll take that one, Tim. We’ve answered this a couple of times. We see no indication that the China buys are pull-ins. There appear to be solid plans behind what they are trying to do and every tool we ship they’re trying to ramp as quickly as they can. So I really don’t think that plays into it. Having said that, we are watching what’s going on with the talk about regulatory controls, but at this point no details that we could even really comment on.

Awesome, Tim. Thanks so much.

Thanks, Tim.

Thank you. Our next question will come from Joe Moore with Morgan Stanley.

Great. Thank you. I wonder – back to the topic of this China sovereign business, if you could give us some color on the number of customers. I think people tend to think about memory, but just I’m not looking for specifics, but how much of it is memory versus other stuff and just an indication of the breadth that you’re seeing?

Yes. So Doug made a comment about the demand being pretty broad based. We are seeing – and again, just sort of think about what’s great about our market right is the breadth of driver – end market drivers. There’s a lot of IoT in specialty technologies whether it be automotive, power devices, image sensors, you kind of see all of that being – people in China trying to address that end demand. And so it’s not isolated to any one thing. Clearly the uptick in memory has outsized importance for Lam’s revenue and basically we watch very closely what happens especially in the NAND and DRAM areas. But really our outlook and the $2 billion to $3 billion increase that Doug talked about in 2020 is pretty broad based across quite a number of customers.

Okay, great. And then you guys have talked about kind of a $70 billion five-year WFE for NAND kind of keeping us on a historic supply growth trajectory. Is that still kind of the right ballpark? And we would seem to be quite a bit lower than that right now. Is that still kind of the right framework for thinking about what WFE ought to be if we stay in a historical demand context?

Yes. That’s still the way we look at it. And our comment as you just said we were quite a bit below that at this point, that was part of our commentary as I said through last year we were actually under investing for long-term demand. That long-term demand is what establishes our $70 billion five-year investment. And even this year as we see a strong uptick in NAND, we still as we said expect ourselves to enter the year maybe slightly still below the long-term demand rate.

Perfect. Thank you very much.

Thanks, Joe.

All right. Thank you. Our next question comes from Patrick Ho with Stifel.

Thank you very much and congrats also. Maybe, Doug, first in terms of being an installed base business and the growth you are seeing there and the sustainability of that growth, can you just give a little bit of color of how you’ve seen maybe over the last few years and going forward how the business has kind of transitioned from I guess the transactional break and fix type of business to more of a contract base which gives you a better visibility into the revenue and cash flow stream of that business?

Patrick, I’m actually going to redirect it to Tim because I think he’ll give you a more comprehensive answer than I would.

Yes, Doug can certainly add something there, but I think we have seen that transition and it’s not just something that’s happened to us. It’s been a strategy we’ve been driving to try to make this business less transactional and much more value add and also much more long term. And I talked in my script about one way in which we do it. You transition the transactional to longer term through multiyear contracts. Even there you’re able to help the customer control their costs in a much more predictable way and that gives us better visibility going forward, makes the business a little less transactional. But I think the biggest way that we’ve transitioned this business from transactional to strategic is really through our focus on new products in the portfolio of services and upgrades that allow the customer to change the cost profile of running their install base. And so in that way you can make this much more strategic. I talked about the Corvus R technology, the self-maintaining tool where the system itself replaces some of its consumable parts rather than having to have technicians going and do that work. When we engineer that type of new upgrade, we then would create for yourself an entire new SAM within your installed base. And now as customers recognize the value of that automated replacement system, they go and they upgrade to all of those older tools that are in the installed base, and it creates another source of ongoing revenue for us. And in the meantime we’re looking for that next upgrade to engineer and offer to the customers. And so I think it’s becoming much more of a product and strategically focused business. It just happens that its targeted market is the installed base we’ve already shipped.

Great, that’s helpful. And maybe as my follow-up question and maybe for Tim since you talked about it in your prepared remarks about the ALD market and the market expansion opportunity there. On top of the share gains you’ve made in that segment as well as the market growing particularly in the foundry/logic space, do you see additional applications at foundry and logic driving this growth or is there an opportunity for it to expand to other segments, like DRAM?

Yes, it already is expanding into other markets. The only difference being again with ALD you’re essentially creating a deposition technology, a platform and that’s one thing that Lam is very good at is we’re creating high-productivity platforms. And then we expand the portfolio of films that we can deposit and that creates more application opportunities for us. As I talked about oxides and carbides, there are other films that are also being developed same time. And I think that ultimately every device type reaches a point where it needs to do some level of atomic layer processing. And so the long term I think this is just where the technology is going and that’s why you see ALD starting to replace, as I said, some older process alternatives for certain steps.

Great. Thank you.

Thanks, Patrick.

Thank you. Our next question comes from Joe Quatrochi with Wells Fargo.

Congrats on the results. I was curious on the NAND flash side. I was wondering if you could talk a little bit about the amount of clean room space that you see across the industry today that’s empty. And then how do you think about just the industry’s kind of use on filling it versus past cycles?

Joe, are you still there? Sorry, you broke up at the end. Okay. There’s plenty of space out there in the industry for sure across all of the customer base. And so what I always say is – in fact I think I don’t know a quarter or two ago we talked about the fact that we were tracking double-digit number of new fabs in 2019. I think the number’s probably about the same in 2020, a lot of those being memory fabs. The thing to understand with our customers is building the shell is – it’s a cheap call option on the future, right. It doesn’t mean we’re going to equip it tomorrow, but it does indicate to you a long-term intention. And then they buy equipment when they really need the output. That’s where the real money and capital gets deployed. But there’s plenty of clean room space out there.

Yes, I guess the only thing I’d add. I thought perhaps you were going to ask about the importance of clean room space and I was going to be able to tell you that that’s one of the things that we focus on. You might have understood in the past from past commentary that a benefit of some of our products, like the Strata and why it’s popular within the NAND market is the number of wafers that we output from that tool per square meter of fab space that consumed is actually the best in the industry. That’s an important metric. Even when Doug says there’s lots of fab space, which I certainly agree with, how they use it is always important to the customer. And so again as we think through platform, design and launching new tools what we call footprint density or throughput density is really one of the key metrics that we focus on.

That’s helpful. Thank you. And then just back on the services side, given that we should start to see I would think an acceleration in the growth of your installed base this year with just a rebound in memory demand, is it fair to us to think about accelerating year-over-year revenue growth for that business in 2020?

Joe, the way I generally think about it is the chambers ship and then they monetize over a period of time after they ship. And so the fact that you saw chambers grow in 2019, that’s a good indicator of what’s going to drive growth in 2020. That’s how I generally think about it. There’s a little bit of a lag to it after the chamber count, which is why historically we’ve given you a chamber count number one time a year at the end of the year.

Thank you.

Thank you.

Thank you. Our next question comes from Mehdi Hosseini with SIG.

Yes. Thanks for taking my question. All the good ones have already been asked. Just a quick follow up for Doug. How should I think about OpEx just roughly beyond the March quarter?

Yes, I kind of answered that already. I kind of didn’t answer it in how I answered it. But what I said was that I’ll give you a new financial model in March. And what I said is over the last several years the same management team is here that’s been around the company for a while. We like to see revenue grow faster than we want to let spending grow so that we deliver some leverage to the bottom line. That’s still very much how we think about it.

But your March quarter shows a typical seasonal uptick and I know we got to wait until March 3, but as we model this kind of fine tune our estimate, should I think of your OpEx remaining at the minimum at the same level? It’s not going to just be a one-time event.

Yes, that’s probably not an unreasonable way to be thinking about it for now, Mehdi.

Good. Very reasonable answer. Thank you.

Thank you, Mehdi.

All right. Thank you. Our next question comes from Mitch Steves with RBC Capital Markets.

Hi, guys. Thanks for taking my question. I think the majority has been answered, but I just want to clarify maybe two small things. So number one is the comments on DRAM, so it sounds like that’s going to be up year-over-year for 2020? I just want to make sure that’s right and there wasn’t anything to read between there? And then secondly, I don’t expect numbers from this, but is the message that you guys believe you’re going to gain more share in NAND relative to the other markets in '20?

I’ll take the first one and then I’ll let Tim comment on the share. I don’t really see when I look at the WFE, the color that we just gave you, a real recovery in NAND I wouldn’t describe it that way – sorry, in DRAM. But clearly in NAND, yes. Foundry and logic continue to be strong. DRAM is kind of push in plus or minus. And what we see happening is there’s still a little bit of inventory out in the channel. It’s got to get burned off. And at some point you can’t continue to sustain supply growth below where demand growth is. And when we look at DRAM bit growth, we think supply growth in 2020 is below demand growth.

And I think a little bit longer term and also relative to clearing the inventory. We’ve been very encouraged by comments we’ve heard about what we understand are drivers for DRAM; the growth in the server market, the introduction of 5G where you’re seeing pretty substantial step up in terms of DRAM content per handset. And so it’s – and I think Doug said this in the past, but even for DRAM a little bit more matter of when, not if. So I think it’s just – right now we have, as you said, maybe about a push for the outlook that we have just given you.

Your comment about NAND, I guess when we think about share or share of total spend, one of the things we’ve talked about is the strength for us in NAND obviously is that we are – and our tools are key enablers of building taller and taller NAND stacks. And as those stacks increase, our share of total WFE continues to increase. And so given that year-on-year we continue to see a greater portion of spend being spent on taller NAND devices, our share of total spend will increase.

Okay, thanks. Perfect. Just really a small one if I could. What was just like a dollar impact to the virus that you guys are taking out of the Q1 just to get an idea?

I’m not going to describe those specific dollars. It was an amount that we think is consistent with what we’re hearing from customers and suppliers.

Okay, understood. Thank you.

Thank you. Our next question comes from Quinn Bolton with Needham & Company.

Hi, guys. Thanks for squeezing me in. One near-term question, one longer-term question. On the near-term question, given the travel restrictions in China around the coronavirus outbreak, can you guys say are you guys having difficulty accessing some of the fabs either in the installed base business or delivering new tools or is it still somewhat business as usual and you have access to service the tools in the fab and you’re able to deliver tools here in the near term?

I think very specifically I think most people are aware of the travel restrictions have been placed on travel in and out of Wuhan. And so obviously you can’t travel into that area where there are some customers located. But in general I think that as Doug said, we’re moving to the Lunar New Year which now has been extended and got abundance of caution Lam is also implemented travel restrictions for our people to kind of business critical situations only. And I think from the standpoint of impact and the way we’ve looked at it is there could be delays of a few weeks in supply chain or shipments to customers and we don’t see that as any real change though to the demand picture that we’ve outlined and therefore we’re really talking about just hopefully seeing this normalize over the next few weeks.

Okay, that’s helpful color. And then the longer-term question is your 2020 WFE forecast I think is higher than probably what many of us were thinking. I guess as I look out to 2021, it sounds like DRAM is not part of the 2020 forecast. Do you think 2021 WFE can continue to trend higher if that DRAM spending comes back?

You know we’re not going to answer that. Even I don’t know what '21 is. When I think about it though, the long-term growth drivers are totally intact. We’ve been talking about this for years, right. You got data exploding in society. You got crowd and hyperscale, the Big 7 what have you investing in more in equipment this year, that’s good. You’ve got 5G on the come line, that’s good. You’ve got density growing there in every phone. So the long term is really very positive for the industry and our position in the industry enabling it we feel really good about where we’re sitting.

Thank you.

Okay, operator, we have time for one more question please.

Okay. Our last question comes from Sidney Ho with Deutsche Bank.

Hi. Thanks for squeezing me in. My first question is on the memory spending this year. If things stay out the way you think, are you thinking that NAND CapEx will still be below that $70 billion run rate? I know you said that you waited [ph] below the 40% bit supply in growth. I guess in a way I’m trying to parse out that $8 billion to $10 billion increase in WFE you guys are forecasting.

Sidney, you know we never give you segment by segment WFE numbers and I’m not going to now. It is going to grow this year. And as Time described, we think bit growth in NAND is in the first half anyway below where long-term demand is and probably exiting the year it’s getting closer to being in balance. But we still think it’s below where demand growth is. I’m going to leave it at that.

Okay. How about DRAM bit supply growth exiting the year if there is – to your point if there is – DRAM CapEx being a push?

DRAM bit was also I think as we said would undergo long-term demand this year.

Okay. Maybe a longer-term question, with the share gains you have in foundry and logic this year and I think it was as high as 48% of the total revenue last year. How should we think about your exposure between foundry and logic and memory through the next cycle? I think versus maybe last five years, memory was averaging like close to 70% sales.

We’ve got nice trajectory rather than what’s going on in foundry and logic. We had a really strong December quarter, record level in foundry. I expect our share of WFE in both foundry and logic to continue to be very strong. I’m not going to pinpoint exactly what it is versus memory because we’re very strong in memory as well. I feel really good about where we’re positioned, I’ll just put it that way.

Well, I think the simplest way to think about it, as a company our objective is to improve our revenue share of WFE across all segments.

Okay, great. Thanks.

Thanks, Sidney.

All right. Thank you. I’d like to turn it back over to our speakers for any closing remarks.

We just want to thank everyone for joining our call today. We appreciate it.

Thank you. Ladies and gentlemen, this concludes today’s teleconference and you may now disconnect. Please enjoy the rest of your day.
