Tim Archer - President and Chief Executive Officer

Thank you, Tina and thank you to everyone joining the call today. Our September quarter results reflect continued strong execution by Lam, with revenues topping $5 billion for the first time in the Company's history. Gross margins came in at the higher-end of guidance and operating margin and earnings per share both exceeded the guidance range.

As you can see from our press release today, we also expect solid performance in the December quarter despite the challenging environment. Recently the United States government announced new export regulations for US semiconductor technology sold in China including wafer fabrication equipment and related parts and services. We have taken the necessary steps to ensure full compliance with the rules and have ceased shipments and support as required.

Our financial guidance issued today for the December quarter includes the impact of these changes. For calendar year 2023, we estimate the total revenue impact from these restrictions to be in the range of $2 billion to $2.5 billion. Turning to the broader demand picture, we see wafer fabrication equipment spending in calendar year 2022 in the low $90 billion (Technical Difficulties).

This outlook includes the impact of new China - China-related restrictions and lower demand, partially offset by improving supply-chain conditions. As some of our customers have indicated recently, there has been a rapid deterioration in demand fundamentals, particularly within the memory segments. Customers are adjusting investment plans into next year to bring channel inventories down to more normalized levels. As a result, we see memory bit shipments tracking below end demand for the next few quarters.

In our normal cadence, we would provide our first view of 2023 WFE on our January earnings call. However, given the current environment, today we are providing our preliminary estimate for calendar year 2023. Inclusive of the China restrictions, we expect next year's WFE to be down more than 20%. With memory investments accounting for a large portion of that decline.

We will provide more detailed color on our outlook in our next earnings call, but for now, we believe that customer actions to reduce memory bit supply growth will create a favorable setup for memory mix to increase as a percent of overall WFE beyond 2023.

As these cyclical adjustments play-out, the structural factors supporting a long-term WFE growth remain unchanged. These include expanding semiconductor content in end devices, rising device complexity and larger die sizes. These factors create tremendous opportunity for Lam, as they require greater etch and deposition intensity to enable higher-performance and more scalable device architectures, including the transition to 3D structures. To ensure we are best-positioned to win long-term, we are focused on three key strategies.

First, continue to demonstrate our commitment to customer success by ensuring that the rapidly-growing installed-base of Lam tools at our customers is operating at maximum efficiency. Second, be a trusted R&D partner for our customers by sustaining our investment in technology development that is most critical to their long-term device scaling roadmaps. And third, accelerate innovation and deepen our customer and supply-chain partnerships by fully leveraging Lam's recently expanded global R&D and manufacturing infrastructure.

Our installed-base is now approaching 80,000 chambers in the field. This is over 30% higher than in the 2019 memory-related pull-back-in WFE. Lam's growing installed-base continues to drive strong performance in our CSBG business, which hit another record in the September quarter with approximately $1.9 billion in revenue. While we won't hit new records every quarter, our installed-base has become ever more important to our business model, particularly in WFE spending downturns.

During such times, customers can continue to advance their technology while optimizing capital efficiency through upgrades to their existing tools. We are also engaging with customers to find other efficiencies including yield enhancement. An example of the opportunity this creates can be seen in our Coronus product-line. Lam's Coronus double etch process is employed by customers to help prevent process-related defects which can impair cost per bit scaling.

As a result, we have seen a steady increase in the number of double etch passes used in each successive NAND technology node. Another opportunity to help drive efficiency can be found in the enormous volume of equipment and process data being generated from our large and growing installed-base. Together with customers, we are using key learnings to deliver services and upgrades that positively impact our customers' operations.

For example, we recently deployed equipment intelligence services to support new equipment installation at a large memory manufacturer. Using these capabilities, we were able to shorten the time to release tools to production by more than 20%. While the near-term demand dynamics warrants an increased focus on operational efficiencies, the strong pull for technology advancement from our customers and the growth opportunity it creates for Lam continues. We made solid progress in the September quarter with key technology wins across multiple customers.

For example, our ability to deposit critical films to lower device capacitance and improve lithography overlay performance led to wins for these layers at leading DRAM customer. For both applications, we leveraged learning from our 3D NAND leadership position as well as ecosystem partnerships to bring innovative and cost-effective solutions to our DRAM customers.

In foundry logic, we secured multiple new ALD application wins at a key customer by delivering purpose modifications and film characteristics required for building and integrating gate all-around structures. Whether it is our focus on operational efficiency or our collaboration of advanced technology, we believe our long-term success will be rooted [ph] it in R&D and manufacturing infrastructure close to our customers, close to our ecosystem partners and with access to world-class talent.

Consequently over the past two years, we have made strategic investments to expand our global footprint, including the addition of a manufacturing facility in Malaysia, an R&D lab in Korea and just last month, the opening of Lam's India Centre for Engineering in Bengaluru. This center is a valuable addition to our global lab network, specializing in the design and testing of hardware and software used across our product lines.

So overall, I am pleased with how we are continuing to strengthen our foundation in technology, manufacturing and service. This foundation puts us in a very good position to both navigate the current cyclical dynamics and emerge stronger as we look to capture the exciting opportunities we see over-time in the semiconductor industry.

Thank you again for joining today and I'll now turn the call over to Doug.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Excellent. Thanks Tim. Good afternoon, everyone and thank you for joining our call today. Lam delivered solid results in the September quarter with record levels of performance across multiple metrics, including revenue, operating income and earnings per share. The September financials reflect our focus on operational excellence and our ability to deliver and meet the needs of our customers in a dynamic industry environment. Revenue in the September quarter crossed the $5 billion mark for the first time in our history coming in at approximately $5.1 billion. We continue to ramp output levels delivering nearly 10% revenue growth over the prior quarter. Supply-chain issues have begun to ease somewhat. They have not gone away completely however.

We continue to deal with certain inflationary pressures as well as output constraints. Deferred revenue was $2.8 billion and grew in the September quarter by approximately $550 million. This growth was primarily due to customer cash and advanced deposits followed by the timing of shipments on outstanding orders. With macro conditions weakening and wafer fab equipment spending declining, I expect deferred revenue and backlog levels will come down as we exit the December quarter.

I'll provide more information regarding our December guidance and focus for calendar year 2023, later in my scripted remarks. Let me now turn to the segment details for the September quarter. Memory represented 52% of systems revenue, which was slightly down from the prior quarter level of 54%. Included in memory, the NAND segment represented 39% of systems revenue compared to 40% in the prior quarter. We see capacity adds and conversions occurring by NAND customers mainly for 192 layer class devices. The DRAM segment concentration was consistent with the prior quarter coming in at 13% of system revenues compared with 14% in the June quarter.

The DRAM investments were primarily from 1z and 1-alpha node conversions. Foundry investments were respectable in the September quarter comprising 34% of our system revenues reaching a record level from a dollar standpoint. The increase in the quarter from the June quarter concentration of 26% is a result of the continued strength in investments to both the leading and mature node devices across the myriad of customers. These investments are supporting areas such as, AI, IoT, cloud, automotive and 5G.

The logic and other segment contributed 14% of systems revenue in the September quarter compared with 20% in the prior quarter. I'll remind you that we had record results in this segment in the June quarter and we continue to have positive momentum in the Logic segment. Our customer-base here is investing in microprocessors, image sensors as well as advanced packaging solutions.

I'll now turn to the regional composition of our total revenue. The China region came in at 30% of the total relatively flat with the prior quarter level of 31%. The China September revenue was more concentrated towards the domestic Chinese customer-base.

And as Tim discussed, we now have additional restrictions for certain domestic Chinese customers and expect the revenue in this region will be significantly lower as we go into next year. The Taiwan region increased to a concentration of 22% in September versus 19% in the June quarter. Korea decreased to 17% of our total revenue from 24% in prior quarter. I expect these two regions to continue to be strong for us based on the plans of our customers in those regions.

The Customer Support Business Group results were strong in the September quarter. Revenue here reached a record of nearly $1.9 billion which was up 16% from the June quarter and 37% higher than the September quarter in calendar 2021. All parts of the CSBG business delivered good performance in the quarter. Notably the Reliant and spares product-line revenues were at record levels.

Reliant was the biggest contributor to the sequential growth in September. As we've noted in the past, CSBG revenues will fluctuate on a quarterly basis. Well, the macro setup creates the likelihood of a decline in trailing edge demand, the strength of our installed base and value-added services provide a platform to offset potentially softer specialty WFE spending.

We do believe nonetheless that the specialty segment will weather next year relatively better than WFE in total. Moving to gross margin. The September quarter came in at 46% at the high-end of our guided range and it increased from June's gross margin of 45.2%. We benefited from higher output levels as well as favorable customer and product mix. We do continue to have cost pressures in freight logistics as well as in certain raw-material areas like semiconductors.

I see headwinds coming in our December quarter related to customer mix, which I'll talk to when I address our guidance. Operating expenses for the September quarter were $647 million, up from the prior quarter amount of $635 million. The increase in spending was in R&D which comprised nearly 68% of our spending, which was a high-water concentration level for the Company. We're focused on supporting our customer's manufacturing plans for both the short and long-term and investing with those objectives in mind.

We're committed to managing spending next year as we see decline in calendar year 2023 wafer fab equipment spending, which will obviously negatively impact our revenue levels. The September operating margin was 33.3% and was over the guidance range due to the higher levels of revenue and improved gross margin. Our non-GAAP tax-rate for the quarter was 13.8%, slightly higher-than-expected due to the geographic mix of income coupled with the impact of the required US R&D capitalization rules.

Our estimate for the December 2022 quarter and for 2023 is for the tax-rate to be in the low-to mid-teens level. Please note this estimate does not reflect the impact of any potential US and global tax policy changes being considered. The minimum tax provisions of the Inflation Reduction Act are not effective for us until the second-half of calendar year 2023, which is our 2024 fiscal year. We do not expect any meaningful impact to our tax-rate related to this policy change however.

And also as a reminder, as we've discussed in the past, you should expect the tax-rate to fluctuate from quarter-to-quarter. Other income and expense came in for the quarter at $30 million in expense. This was an expected decrease compared with the $87 million of expense in the June quarter. I'll just remind you that we incurred a loss related to-market declines in one of our venture investments last quarter. We have now liquidated that position.

Other expense in the September quarter was a little bit better than we expected mainly because of higher interest rates on an increasing cash balance and slightly favorable foreign-exchange impacts. The OI&E P&L line item is subject to-market related fluctuations that will cause some level of volatility to the items such as foreign exchange, as well as impacts from the equity markets. From a capital return perspective, we allocated approximately $105 million to share repurchases during the September quarter.

The cash was deployed in open-market repurchases. The ASR from the June quarter also continued to execute in the September quarter. We paid $206 million in dividends during the quarter. And just to remind you, we continue to target returning 75% to a 100% of our free-cash flow as our long-term capital return plan.

September quarter diluted earnings per share came in at $10.42, which was above our guided range because of the strong revenue and improved profitability performance that I spoke about. Diluted share count was 137 million shares which was lower than the June quarter and was in-line with September quarter expectations. Let me now pivot to the balance sheet.

Cash and short-term investments including restricted cash totaled $4.6 billion which was up from the prior quarter level of $3.9 billion. We generated solid cash from operations in the September quarter of $1.2 billion which was partially offset by the share repurchases and dividend payments. Inventory turns were consistent with the prior quarter level coming in at 2.5 times.

Days sales outstanding was 82 days which was a slight decrease from the 85 days in the June quarter. Noncash expenses for the September quarter included approximately $71 million for equity comp, $64 million for depreciation and $12 million for amortization. Capital expenditures for the September quarter were $140 million, a little bit higher than June which was $126 million. Capital expenditures are supporting growth in manufacturing facilities in the United States and Malaysia.

Additionally, we are investing in research and development infrastructure in California and Oregon as well as our new technology centers in Korea and India. We ended the September quarter with approximately 18,700 regular full-time employees, which is an increase of approximately a 1,000 people from the prior quarter. We had headcount growth primarily in the factory and field organizations and some in R&D to address higher output levels, to manage the supply-chain constraints and to support customer deliveries and installations. We decided to slow down hiring for only critical positions, as we assess the business trajectory going into 2023. Overall, we're executing well in the short-term while we plan to prudently manage the business for a down WFE year in calendar year 2023.

I'll remind you that we know how to manage this business during a down-cycle. Our operating model has been constructed and tested for many years in different business environments. With that backdrop, I'll provide our non-GAAP guidance for the December 2022 quarter. We are expecting revenue of $5.1 billion, plus or minus $300 million.

This includes our current estimate of the impact of new regulations on our ability to supply products and services to certain customers in China. This revenue guidance would have been decently higher if not for these new regulations. Gross margin of 44.5%, plus or minus one percentage point. This is down from the September quarter primarily due to customer mix. We have lost more profitable business from the China region.

Operating margins up 31.5% plus or minus one percentage point and finally, earnings per share of $10, even plus or minus $0.75 based on a share count of approximately 136 million shares.

So let me just wrap it up. Throughout 2022, we've demonstrated the ability to deliver record financial performance and profitable growth. It's been a year of volatile supply-chain constraints, inflationary pressures and regulatory changes. We're confident we're prepared for the challenges we see in the industry in calendar 2023. And we built a solid foundation for continued success, evidenced in our technology leadership and robust installed base.

Operator, that concludes my prepared remarks, Tim and I would now like to open up the call for questions.

Question & Answers

Questions and Answers:

Operator

Thank you sir (Operator Instructions) We will take the first question on the queue from Timothy Arcuri. Your line is open. Please go-ahead.

Unidentified Participant - - Analyst

Hi, thanks a lot. This is Jason on for Tim from UBS. I just have couple of questions. So my first question is on your December guidance, you just guided the deferred revenue to come down, so I was just curious whether you can quantify for us how much of excess deferred revenue, you are realizing and contemplating into your December guide, then, I have a follow-up. Thanks.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah, I'm not sure I completely heard you. I think you asked what we think deferred revenue in December is going to do at all? I'm going to tell you is, I expect it to go down, I am not going to quantify it for you.

Unidentified Participant - - Analyst

Got it. Thanks a lot, yeah so my second question is on the gross margin for the same quarter. Could you please quantify how much of headwind you're still facing in December for things like elevated freight costs and Malaysia facility, when can we expect the gross margin to normalize eventually? Thank you.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah, no, I'm not going to quantify that for you either. It's still a headwind, otherwise, I wouldn't have put it in the scripted remarks. As we go into next year and I think, supply gets caught up with demand in terms of some of the supply challenges we're having, I expect some of the inflationary headwinds there to mitigate. I expect the same thing in freight and whatnot, so, I'm not going to put a number on it, but I do expect that that will get better as we go into next year.

Unidentified Participant - - Analyst

Thanks a lot.

Operator

We'll take the next question from Harlan Sur from J.P. Morgan, your line is open. Please go-ahead.

Harlan Sur - J.P. Morgan - Analyst

Yeah hi good afternoon. Thanks for taking my question. Given - given your commentary on a $2 billion, $2.5 billion [ph] impact next year from export controls in China, looks like near-term you are offsetting some of that with - with your significant deferred revenue and order backlog with some of your non-China customers, but I guess my question is could you quantify of the $2 billion, $2.5 billion impact, what percentage is systems and what percentage is services and then I have a follow-up question.

Doug Bettinger - Executive Vice President and Chief Financial Officer

I mean, Har, you go ahead.

Tim Archer - President and Chief Executive Officer

Yeah, Harlan. I guess, we wanted to give some, some sizing for that in 2023 since we knew there would be questions but we're not - we're not going to break-out the difference. Right now that's inclusive of both systems and spares and service for those customers in China that are impacted by the restrictions.

I think that we talked a little bit about improving supply-chain conditions and so where possible we talked about December, including some impact of, of course China restrictions, offset partially by supply-chain easing, offset as well by some decreases in the - in other customers due to the demand elements that we talked about. So we're not prepared to break each of those items out but we're doing best we can to essentially meet customer demand requirements, where we can as early as we can.

Harlan Sur - J.P. Morgan - Analyst

Well. I appreciate that. And then my follow-up, the team only just started recently breaking out services for your CSBG business, obviously it's becoming a more ratable base, multi-year service contract, focused business, lot which are in terms of value-added services and solutions.

I think you guys put in your presentation like chamber shipments are up significantly over the past three years, so in thinking about a weaker WFE environment next year, like if you look-back over the last three or four WFE downturns, has the Lam - has Lam services business remained stable or grown through most of those downturns and, would you expect a similar profile in a weaker WFE environment next year?

Tim Archer - President and Chief Executive Officer

Well Harlan. No [ph]. In my comments, I specifically said, it's a very important part of our business model, especially during WFE downturn, it's also been a very deliberate strategy of Lam. I think if you attended the last couple of Investor Conferences we've talked about an intention to increase revenue capture per chamber and so, I mentioned that just - just in the time from the last WFE downturn in 2019 from now, we've managed to grow the installed-base in chamber count by more than 30%. At the same time we've also increased the breadth of our portfolio, the services that both in terms of the types of equipment intelligence services despairs the upgrades, that is also meaningfully improved our opportunity for each of those chambers that's in the installed-base.

So each element of the spares, CSBG whether it's spares upgrades, services, Reliant, probably moves a little bit different through [ph] each of the kind of WFE up cycles or downcycles, but generally spares, as we've said holds up pretty well as customers - those customers continue to run all of the tools that they got installed.

Upgrades sometimes can actually do a little bit better as customers have a little bit more time in a downturn to make the improvements that they want to make, so they come out of those downturn stronger with their installed-base. And then services. Especially with our expanding offerings around equipment intelligence services, I talked about efficiency, productivity, those are all, things that, they are important to customers at all times but they're really important to customers as they are thinking about squeezing everything they can out of - out of the installed base they have and being able to then maybe delay additional capital purchases or expenditures for just a bit longer so.

I would say that we see CSBG as a very important part of stabilizing the Company's performance through cycles.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah Harlan, the only thing I would point out incrementally - yeah the only incremental thing I'd point out incremental to what Tim said is, you know, I've been talking about how strong Reliant has been the last several quarters and in fact last quarter it was the biggest sequential grower in CSBG.

And as we look into 2023, we're not going to parse all the different components of WFE, but I know there's some people out there that think the specialty segment of WFE will - will soften next year and that would impact Reliant. Along with that - offset by the things that Tim talked about.

Harlan Sur - J.P. Morgan - Analyst

No, great insights, thank you.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Thanks, Harlan.

Operator

We will take the next question from C.J. Muse from Evercore, your line is open. Please go-ahead.

C.J. Muse - Evercore - Analyst

Yeah, thank you for taking the question. I guess first question relates to deferred revenues. So when you gave us your early view for 2023 WFE. How are you kind of reflecting deferred revenues for you as well as the rest of the industry in that more than down 20%. And as part of that should we be thinking about your deferred revenues getting close to 0 exiting calendar '23?

Tim Archer - President and Chief Executive Officer

Yeah, let me take a shot at that first and then I'll let Doug add-in. I - obviously our - we contemplated that always we're talking about the - what we think the industry is able to do from a ship [ph] perspective and ultimately from a revenue perspective, but. So that number next year kind of think about it as a little bit of a like for like to this year. But, I believe that we will see ultimately the year play-out in a way that deferred revenues do come down and supply-chain continues to ease and there is a normal level though. I'll let Doug speak to that what that normal level of preferred is that we'd expect. So won't come to zero, but we will see a meaningful portion of that deferred revenue that really represents the systems that we were [ph] unable to satisfy this year as that plays out next year as we have ramped our capacity, supply-chain capacities caught up and therefore, we get caught up on deliveries and revenue recognition. So, Doug, I don't know if you have something further?

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah. I mean C.J., you know that deferred revenue is never a zero number because we always have these cash in advance payments, volume purchase, agreement credits, the whole bunch of different things, spares and service credits that are there. If you look pre the supply-chain challenges we had, a normalized level of deferred revenue would be somewhere between 500 [ph] and $1 billion, it bounces around, it's lumpy sometimes. But that is kind of the normalized level that I think about and it's elevated right now because of the backordered stuff and the incomplete tools that we're shipping, it will come down in December and then it will come down more as we go through 2023 is our outlook right now.

C.J. Muse - Evercore - Analyst

Very helpful. And as my follow-up, you've grown your headcount by 30 plus percent over the last kind of five quarters and I guess, curious as you contemplate the coming kind of correction. How are you thinking about headcount? How you are thinking about OpEx and operating leverage?

Tim Archer - President and Chief Executive Officer

Well. I think that obviously as Doug mentioned in his comments, it's not our first downturn and the reality is we hadn't - really had no choice but to expand the Company as we tried to meet what was really unprecedented demand over the last couple of quarters - sorry couple of years and that no choice in doing that and as you see, not only did we add head count, we also expanded our facilities. Obviously as you move through cycles, you then look at the resources that are required to meet the business level in the year and going forward and beyond. But I made a couple of comments, one, we think it's incredibly important that we sustain technology development through many cycle.

Our customers expect for us to be continuing to advance the products and technologies that can meet on the other side of the demand cycle. And two, I talked about some very strategic investments that we've made to expand our global footprint to put us closer to where some of our key customers are to create capabilities closer to ecosystem partners in our supply-chain and we think those investments are incredibly important to the long-term business model of the Company and so we'll be sure that in however we're thinking about the resources in the Company that we sustain those types of investments as well, because it's not only how you act through the downturn, it's how prepared you are for the next upturn and what performance you can deliver in that cycle as well.

So, those things are all under consideration now and it's also why we gave you some look ahead to 2023 to give you a sense of how we're thinking about how this business is going to have to run through the near-term.

C.J. Muse - Evercore - Analyst

Very helpful thank you.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Thanks C.J.

The next question from Stacy Rasgon from Bernstein Research, your line is open. Please go-ahead.

Stacy Rasgon - Bernstein Research - Analyst

Hi guys, thanks for taking my question. So my first question, you've, obviously your - you got backlog and deferred carrying you through December. So you've got calendar '23, you're guiding WFE down, if I do the math like somewhere in the ballpark of $70 billion, how do I think about the transition from where we're running right now to that environment? Like, can you give us any color even qualitatively just on like for March quarter, does March quarter sort of - are you sort of at that run-rate of where you expect WFE to be next quarter, like, what does that transition look like?

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yes, Stacy. I mean we gave you color beyond what we would normally do at this point in the year and I'm not going to do any more than we've already provided. That's the best we are going to be able to do for you right now.

Stacy Rasgon - Bernstein Research - Analyst

All right. I guess, I'll take that. For my follow-up, if I look at the WFE guidance for next year again down 20% or more from the low 90s puts it about $70 billion, you said it includes the China sanctions. Would it have been higher without those China sanctions, are you assuming that some of that China capacity gets redeployed to other players? Like what does that - what are those puts and takes look like?

Tim Archer - President and Chief Executive Officer

No we - that makes an assumption, then fair that - the vast majority of that China WFE, just comes out of WFE. And I don't - if your question is could somebody else spend what those customers were going to spend that same equipment or capacity in-place, our view right now, I mean is that that probably wouldn't take place in 2023.

Stacy Rasgon - Bernstein Research - Analyst

Yeah. I guess, what I'm asking is if it wasn't for the China sanctions, would you be looking for WFE like $80 billion or $75 billion instead of the $70 billion, where it seems to be coming out?

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah, it would have been a little bit higher, Stacy.

Tim Archer - President and Chief Executive Officer

Yes.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah. It would have been a little bit higher.

Stacy Rasgon - Bernstein Research - Analyst

Got it okay, thank you guys.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Thank you.

We will take the next question from Krish Sankar. Your line is open, please go-ahead.

Krish Sankar - Cowen and Company - Analyst

Yeah hi, thanks for taking my question. I have two of them. So first one, thanks for the color on CSBG. I'm just kind of curious, you shipped a lot of them this year, most of them are under one year warranty, so they won't necessarily contribute to CSBG revenue. And WFE is down 20% or higher and the customer utilization rate come down. Is there a way to think about, what utilization rate below which actually CSBG revenues don't grow?

Tim Archer - President and Chief Executive Officer

Well, yeah, I think it's a tough question because as I, that's why I pointed out, there's only four components of CSBG not all of them are completely utilization-driven, but just to your comment about the number of tools we've shipped and over the last two years, as we mentioned or since 2019, up 30%. So significant expansion in chamber count. So therefore our opportunity has grown. There are some components of CSBG in the spare space around consumables that actually start kind on customer usage and so that one year delay, which doesn't quite exist for every part of CSBG spending.

But I don't think we've done the calculation of where UG [ph] would have to come down, utilization would have to come down in order for certain elements not to grow. I think we anticipate that again customers are going to be motivated to run the tools to a great extent or the tools they already have installed and again, you'll see probably heightened interest in upgrades versus new capacity additions which is also beneficial for not only our CSBG business but Lam's capture rate per dollar investment spend. So, again just CSBG being an important part of our business. Pointing out, Doug also commented some elements like Reliant are subject to kind of overall macro-environment, we accept [ph] to watch those as we move through next year.

Krish Sankar - Cowen and Company - Analyst

Got it. Got it, Tim that's very helpful. And then as a follow-up, it seems like the first time your foundry revenue has crossed $1 billion in the quarter. And you mentioned about some ALD wins (inaudible) all-around et-cetera, so, I'm curious how much of the foundry strength is fair gains versus just underlying cyclical trend from the foundry purchasing?

Doug Bettinger - Executive Vice President and Chief Financial Officer

Little bit of both, Krish, frankly. Obviously, I think you understand like, I'm sure everybody on the call does. Foundry investments pretty strong this year. So that's a part of it but there is incremental positions that we want. Tim, every earnings call talks about some of those. So and he talked about a couple just now.

Tim Archer - President and Chief Executive Officer

Yeah Krish, I'm usually trying to focus on how we're doing versus what are some of the longer-term inflections that we've highlighted. And you [ph] think about foundry logic where we've been focused, it's ALD which, clearly, we've made significant progress.

It's areas like the EUV patterning module which includes hard masks and the ability to etch very fine-pitch features with incredibly uniformity across the wafer and wafer to wafer, tool to tool, chamber to chamber and that's - so I've been, usually I'm talking about a little bit further ahead, but that gives you some sense of the momentum of the Company that's independent of the cycle. It's really - those are positions we are winning and when the customers buy those become big opportunities for the companies.

Krish Sankar - Cowen and Company - Analyst

Got it, thanks Tim, thanks, Doug.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Thanks, Krish.

The next question from Joe Moore from Morgan Stanley, your line is open please go-ahead.

Joe Moore - Morgan Stanley - Analyst

Great. Thank you. In terms of the business that's impacted by the export controls, you said $2 billion to $2.5 billion for next year, can you talk about what that is kind of like on a run-rate basis or just, I'm trying to get a sense of is that $2 billion to $2.5 billion was that projecting some growth relative to where the numbers have been? I'm just trying to understand that - how much the - that the negative impact is versus the trailing numbers?

Tim Archer - President and Chief Executive Officer

Yeah that's a good question. Obviously, we're giving '23 a little earlier that we probably have a great look at '23. But in that number $2 billion to $2.5 billion, we did anticipate some growth in '23 over 2022. So we won't say how much but it incorporate some growth from the run-rate we see today.

Joe Moore - Morgan Stanley - Analyst

Okay, thank you. And then within the service, the spares in particular. Part of that business, I assume you'll be impacted in your ability to ship spares going-forward as well. Should we think about those customers being similar in size to their overall capital spending or have they been sort of purchasing spares ahead of this and could they be outsized exposure within your services business because of that?

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah no Joe, there's not an enormous amount of it - there has been a little bit inventory. I think the entire customer-base built-up with some of the supply-chain constraints this year including the local Chinese customers but it's not like a crazy amount.

Joe Moore - Morgan Stanley - Analyst

Great, thank you very much.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Thanks, Joe.

Next question from Toshiya Hari from Goldman Sachs, your line is open, please go-ahead.

Toshiya Hari - Goldman Sachs - Analyst

Great thank you so much. I was hoping, Doug, you could help us think about your systems revenue into '23 vis-a-vis how you're thinking about WFE. Obviously you are over-indexed to memory where, you guys expect the bulk of the decline to come in in '23. You've been really successful in China and a chunk of that is coming out on the positive side, you seem to have really strong momentum in both logic and foundry, so net-net is it fair to assume you guys can kind of perform in-line with WFE or do you think '23 is going to be a relatively challenging year just given your mix?

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yes. I think in many ways Toshiya, you answered your own question. Yeah, we're a little bit over-indexed to memory. We're very strong in terms of share there and that's going to be down more than overall WFE next year but that's also offset by the strength of our CSBG business, which I believe to be the highest-quality installed-base business in the industry, so that's going to benefit us.

If you really want to kind of see what it might look like. Go back and look at '19, where you had a similar profile, where memory was quite soft and foundry logic was pretty good and we weathered that period pretty well.

Toshiya Hari - Goldman Sachs - Analyst

That's helpful. Thank you. And then as my follow-up, a question on gross margin, you said you're guiding December down a 150 basis-points. And Doug you spoke to customer mix. One of your competitors, they've talked about inventory write-downs and costs associated with repurposing tools, curious if anything like that is negatively impacting your December quarter guide?

And, I guess more importantly, how should we think about margin beyond with volume declining, could gross margins decline further from here or do you think there are enough offsets in pricing and hopefully freight and semiconductor pricing that could - that could help you on the upside? Thank you.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah let me unpack a little bit. Toshiya, no. I don't really think we're going to have a meaningful inventory exposure, so no there isn't anything from that. We believe we're going to be able to meaningfully rework any inventory we had that might have been targeted for those specific customers we can no longer ship to. And I don't think as I sit here today that's a material number. So the softness - sequential softness in December gross margin is because we lost some very profitable customers in the China region and that's going to persist, obviously. So that was kind of the first question.

And unpacking next year, I mean the way I think about it first. I think, you know, as everybody in call knows, this isn't really a fixed-cost business, it's highly variable. And so as volumes vary, a lot of cost-of-goods-sold varies. You've seen that from us over the years, so that that hasn't changed, the model here hasn't changed. As we go into next year, the benefit, I think we'll see in gross margin is I believe we'll see mitigation on some of these inflationary pressures. I think, supply gets back caught up with demand in terms of our supply base in areas like semiconductors.

I believe freight gets better next year to what magnitude I'm not positive, but I think, that gets better. And then we ramped supply-chain in Malaysia so we're flying things shorter distances and whatnot and so we're going to see the benefit of that offset then by, we've just lost some very profitable customers. And yeah volume will be down. There is a little bit of fixed costs in the factory and field that we're going to have to - have to deal with. So I'm not going to quantify it for you but those are the puts and takes.

Tim Archer - President and Chief Executive Officer

And Toshiya, the only thing I would add is - is that a lot of our actions again I spoke to some of the repositioning. I mean, effectively your questions about next year but we're really thinking about again long-term trajectory for profitability of the Company which both Doug and I have said over time, we want to drive it meaningfully higher. And so Doug mentioned it and I mentioned the investment in Malaysia. We talked about the engineering activities in India, backlog [ph] the technology lab in Korea.

All of these things are designed to make us faster and more efficient in our operations over the long-term. And so how much of that shows up next year and kind of how - what the effect is, going to [ph] see how next year plays out, we're going to be focused on it. We certainly go back to look at 2019, we do pretty well in these periods. But really what we're trying to message is that the investments we've made over the last couple of years taking the advantage of this very strong growth period in the Company really sets us up for the remainder of this decade to really drive the strategy of the Company towards again speed, innovation [ph] and efficiency in delivery of our products and services.

Toshiya Hari - Goldman Sachs - Analyst

Thanks guys.

Next question from Vivek Arya, Bank of America, your line is open, please go-ahead.

Vivek Arya - Bank of America - Analyst

Thanks for taking my question. For the first one, I'm curious, Tim, when do you see your ex-China memory customers getting to some level of supply-demand equilibrium. Is it sometime in Q1, Q2, Q3? Just - what's your sense of how much inventory do they have and how much time would it take for them to clear it out so that your - your orders can resume?

Tim Archer - President and Chief Executive Officer

Yeah, well now we're starting to talk a lot more about 2023. And so again we - we incorporated our view there into the 2023 guidance. So I think, we'd like to wait until - until we get little bit closer to the year to be able to speak to that. It's - customers are taking action and I think that you're hearing from the customers about some pretty aggressive actions to try to bring those inventories and - and the supply-demand better into balance.

I don't really want to speak for them but I think that as I commented, I think as we exit 2023, we're going to be set-up in a pretty good place for memory spending as a percent of total WFE to actually price from that point. How it plays out to 2023, we will let you know our view as we get little bit closer.

Doug Bettinger - Executive Vice President and Chief Financial Officer

And Vivek, maybe just an observation from me. I mean these cycles have similar timeframes associated with them almost just walk back in history and look at it. With the caveat though, I think as we came through all the supply-chain challenge at this time, maybe a little more inventory got built-up, when I look at things in the industry, so it might be a little bit longer than typical but these things are pretty consistent on a historical basis, so you just go look at history, you'll have the answer to your question.

Vivek Arya - Bank of America - Analyst

Right. And for my follow-up. I'm just trying to reconcile the more optimistic comments about growth made by your lithography peer this morning, who is expecting to grow next year with your comments that WFE could decline over 20%, so if the litho part of the wallet is going to grow, does it mean that the part that applies to you declines a lot more than 20%?

I'm just trying to reconcile such a big difference in how two important players are thinking about next year.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah hard for me to tell you what another company is saying especially because it was just this morning and, I haven't really been able - Tim and I haven't really been able to look at what they said. But I think you understand, you don't just buy one tool, just for the fun of it, if you can't buy all the process tools to complete the manufacturing line.

It makes no sense right and so, it's about the litho tool eventually need etch step and everything else to complete the wafers. So I can't help you reconcile what they said because, I haven't actually been able to study it. But I think, you understand what I just commented on.

Vivek Arya - Bank of America - Analyst

Understood, thank you, Dough.

Tim Archer - President and Chief Executive Officer

Next question from Blayne Curtis, Barclays, your line is open, please go-ahead.

Blayne Curtis - Barclays - Analyst

Hey guys, thanks for taking my question. I just wanted to ask you on the restrictions. I mean, I guess just optically looking at it, it seems like you're taking out the domestic memory vendors and I know there's very little leading-edge logic. I just kind of curious, there leads with [ph] some debate as to whether the multinationals, whether you could still ship to their Chinese facilities.

I know, there were some licenses maybe for services, so just kind of curious if you could just quantify your understanding of the restrictions and what you're taking out. And whether includes multinationals and if you can still ship to facilities that may make leading-edge foundry processes even if the equipment is not being used for?

Tim Archer - President and Chief Executive Officer

Okay bunch of - bunch of questions there. First - first of all maybe the simplest is we've taken out the - obviously the shipments that were destined for applications where customers that are restricted which primarily means right now domestic Chinese customers that are manufacturing restricted technologies which in NAND and DRAM have certain specifications and in foundry logic, others. The multinationals as we noted were given a - an authorization to receive shipments and service and so our business there effectively remains unchanged as a result of that and so we are continuing to include that in our outlook for 2023. To your point about a facility, it's our understanding that the facility that would have mixed-use would likely fall under the restricted category and so therefore, if a customer were to want to manufacture and take shipments and receive support for a restricted tech - for a unrestricted technology, it would have to be in a facility that was clearly not also doing restricted activities.

And I think, that that's something that's being worked through by our customers. We've contemplated all of those as well as what we believe, what happened in China into that $2 billion to $2.5 billion estimate. And so that's our view right now and the restrictions probably effect customers in our business.

Blayne Curtis - Barclays - Analyst

Thanks. And then just on December, I was little confused, the impact you laid out, it's 500 plus million per quarter that you can't ship to - your sales are kind of flat, so I'm just kind of curious are you making it up with other customers? I just kind of curious how fungible is the equipment that you thought you are going to be shipping to Chinese memory whether it needs to - can be repurposed in the quarter and you're doing that and that's why, you're not seeing the impact or whether you are expecting to ship to some higher-level and we just didn't know that and that's why the sales are flat?

Tim Archer - President and Chief Executive Officer

Well. I think that as here [ph], Doug said the December guide would have been decently higher if the China restrictions have not been put in place. So I think, that answers the question. There was a comment about whether we made about, perhaps we've made-up a little bit because of easing supply-chain conditions but that would have - that would happened independent, so in any case, December would have been higher that the Chinese restrictions not been put in

Place.

Blayne Curtis - Barclays - Analyst

Okay thanks.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah thanks, Blayne.

The next question from Joe Quatrochi, Wells Fargo. Your line is open.

Joe Quatrochi - Wells Fargo - Analyst

Yeah, thanks for taking the question. I just wanted to go back on the expectation that deferred revenue declines in the December quarter. Is there any part of that that's related to the export restrictions, where customers that are now restricted had tools that were incomplete that are now, I don't know, more or less stranded?

Doug Bettinger - Executive Vice President and Chief Financial Officer

No Joe, there's not. We cannot ship anything to those restricted customers.

Joe Quatrochi - Wells Fargo - Analyst

But tools, I guess that were previously shipped that are just incomplete like they were shipped last quarter or two quarters ago.

Doug Bettinger - Executive Vice President and Chief Financial Officer

If that situation existed and I'm not saying, it did or it didn't. We can't ship anything to them.

Joe Quatrochi - Wells Fargo - Analyst

Got it, okay. And Tim, just trying to think about bit shipments and in the cycle relative to the prior cycles, how do you think about your customers' willingness to hold more inventory on their own balance sheets this cycle relative to prior cycles? Does that change the way you think about maybe like the snapback in terms of like bit supply growth?

Tim Arcuri - UBS - Analyst

Yeah, it's a good question, probably it definitely, one that's better - relative to their tolerance of holding that inventory. I think, everybody's view of inventory probably changed a little bit as a result of shortages and and the ability to respond to what - over the last two years, we've seen is relatively sharp changes in-demand. But I really can't answer for them about their willingness to hold more inventory. I think, we're going back and as Doug said, looking at kind of historical behavior in these kinds of downturns, what we're experienced with and that's how we kind of like project out what we think will likely happen.

Joe Quatrochi - Wells Fargo - Analyst

Got it, okay, thank you.

Doug Bettinger - Executive Vice President and Chief Financial Officer

Yeah, thanks, Joe.

Operator

Understood. We have the last one from Quinn Bolton, Needham and Co. Your line is open, please go-ahead.

Quinn Bolton - Needham and Co - Analyst

Thanks for squeezing me. Tim, there is some confusion, you said, interpretation of the market, it seems like on the license requirements for US citizens in China and I wondered if you could just clarify, does this support license requirements affects just the same set of customers as the equipment license or is there a broader impact on US citizens operating in China?

Doug Bettinger - Executive Vice President and Chief Financial Officer

On US citizens operating in China, I'm not -

Tim Archer - President and Chief Executive Officer

Yeah, there is a restriction on US citizens, as defined by the government. The - providing support for the development of restricted technologies.

Quinn Bolton - Needham and Co - Analyst

Right, but is that just sort of the same set of customers that require export licenses on the equipment side, so the advanced NAND, the DRAM and 60 nanometer and below or is there a broader set of customers you cannot support under the export control?

Doug Bettinger - Executive Vice President and Chief Financial Officer

No, I believe it is - I believe it is that same - the same set that's spelled out. Fundamentally customers that are either on a restricted list or producing restricted technologies are those that are effected.

Tim Archer - President and Chief Executive Officer

That's right.

Quinn Bolton - Needham and Co - Analyst

Got it. Thanks for the clarification and just quickly, Doug, you said, you're going to manage OpEx next year. Kind of wondering if you might be able to freight any sort of qualitative color, is that sort of - you expect it to look similar to what happened back in 2018, 2019 in the downturn or would you look to be more aggressive and try to manage OpEx more in-line with the decline you see in WFE in calendar '23?

Doug Bettinger - Executive Vice President and Chief Financial Officer

We'll give you that guidance in the January earnings call. I think what we're just trying to signal is that we're well aware of what we believe is coming next year and therefore, we'll take the appropriate actions, as we see fit, as I mentioned to manage the Company through the downturn but also be ready for what we believe is a must future for the Company and the industry.

Quinn Bolton - Needham and Co - Analyst

Great.
