Ladies and gentlemen, thank you for standing by, and welcome to the MKS Instruments Q4 and full year 2021 earnings call. At this time, all participants are in a listen only mode. After the speaker's presentation, there'll be a question and answer session. To ask a question during the session, you need to press star one on your telephone. If you require any further assistance, please press star zero. I would now like to turn the call over to your host, David Ryzhik.
Good morning, everyone. I am David Ryzhik, Vice President of Investor Relations, and I am joined this morning by John Lee, President and Chief Executive Officer, and Seth Bagshaw, Senior Vice President and Chief Financial Officer. Yesterday, after market close, we released our financial results for the Q4 and full year 2021, which are posted to our website, mksinst.com. As a reminder, various remarks about future expectations, plans, and prospects for MKS comprise forward-looking statements. Actual results may differ materially as a result of various important factors, including those discussed in yesterday's press release and in the most recent annual report on Form 10-K, and any subsequent quarterly reports on Form 10-Q for the company.
These statements represent the company's expectations only as of today and should not be relied upon as representing the company's estimates or views as of any date subsequent to today, and the company disclaims any obligation to update these statements. During the call, we will be discussing various financial measures. All forward-looking financial measures exclude any contribution from Atotech Limited, the acquisition of which we expect to close by the end of the Q1 of 2022. Also, unless otherwise noted, all income statement related financial measures will be non-GAAP other than revenue. Please refer to our press release for information regarding our use of non-GAAP financial results, including reconciliations to our GAAP financial measures. Now, I'll turn the call over to John.
Thanks, David. Good morning, everyone, and thank you for joining us today. Before I discuss our quarterly results and current market trends, I would like to take a moment to reflect on the past year. 2021 presented MKS with a number of unexpected challenges and unique circumstances, yet also significant opportunities for growth, and we seized them. Against this backdrop, I'm extremely proud of what our employees accomplished this past year as we marked our 60th anniversary. Our strong Q4 capped a year in which we delivered record performance in both semiconductor and advanced markets, despite unprecedented supply chain constraints and continuous COVID disruptions. We overcame these challenges by executing with laser focus on meeting our customers' needs while ensuring the safety and well-being of our employees, which remains our highest priority. Our focus on meeting our customers' needs did not impact our strategy for the long term.
We invested in a number of areas to drive organic growth while executing on strategic M&A opportunities. Our acquisition of Photon Control, which we closed in July, brought us critical temperature sensing, which is a seamless fit within our surround the chamber portfolio. We expect our pending acquisition of Atotech will add valuable chemistry expertise, enhance the breadth of our innovation capabilities, and accelerate our customers' roadmaps in this era of miniaturization and complexity. We also made important strides in strengthening MKS by prioritizing our corporate social responsibility efforts. We issued our inaugural CSR report in which we articulated our strong commitments to diversity, equity, and inclusion, as well as environmental management, employee development, and governance. All of these achievements, combined with attractive industry tailwinds, positions MKS for an exciting 2022. Now let me discuss our Q4 results in more detail.
We delivered revenue of $764 million and net earnings per diluted share of $3.02, both above the midpoint of our guidance range. Sales to our semiconductor market further strengthened in the Q4, growing 1% sequentially and 26% year-over-year. Our results were strong across the board, from our well-established vacuum subsystems portfolio to our emerging photonics business. With our broad and unmatched portfolio, which we estimate serves greater than 85% of WFE, we play in every critical semiconductor manufacturing process in the world today, including deposition, etch, wet clean, lithography, metrology, and inspection. Our performance this past quarter and year was a clear reflection of that. Demand across our vacuum portfolio was robust, led by another strong quarter in RF power solutions.
We continue to extend our market leadership in RF power for dielectric etch, particularly for 3D NAND. We believe we took additional market share in RF power generators in 2021 on top of our gains in 2020. This puts us in an outstanding position looking ahead, and we anticipate industry investments into vertical scaling will be a driver for years to come. We are also executing on our strategy to gain share in RF power for conductor etch. As a reminder, this is a meaningful, untapped opportunity for us, and we believe we can harness the technical expertise and know-how that define our leadership in dielectric etch and extend that into a growing share position in conductor etch.
In the past, we have talked about how important it is to secure design wins for the future growth, and we are now beginning to see revenue from these design wins in conductor etch. While we are still in at an early stage, the incremental progress we are making is tangible, and is corroborated by multiple OEMs ramping with MKS RF power generators for conductor etch. We also delivered record quarterly revenue in a number of other categories, such as our market-leading pressure measurement and plasma and reactive gas solutions. We continue to see healthy demand for our dissolved ozone and dissolved ammonia solutions used in wet clean applications, with particular interest from our foundry customers. We delivered another quarter of significant sequential and year-over-year growth in photonic solutions for semiconductor applications, driven by lithography, metrology, and inspection customers, as well as critical temperature sensing for etching customers.
As we look ahead to the Q1 of 2022, we expect revenue in our semiconductor market to be consistent to slightly down with Q4 levels. Demand trends remain strong, but supply chain constraints will continue to be a factor near term. Shifting to our advanced markets. Revenue exceeded our expectations, growing 6% sequentially in the Q4 and 1% year-over-year. We were pleased to see a recovery in revenue from industrial applications, and we also delivered healthy sequential growth in advanced electronics applications. Demand for our flexible PCB via drilling solutions was consistent with our expectations. As we look into the Q1 , we have less visibility than usual into the flex drilling market due to the uncertainty associated with supply chain constraints. As visibility improves, we are well-positioned to quickly respond to our customers' needs.
We continue to focus on our high-density interconnect via drilling opportunity, leveraging the successes we have already made in high-volume manufacturing. We received a follow-on multi-unit order for our Geode HDI solution from one of our key customers that had previously qualified us and has been operating multiple tools over the past year in high-volume production. We also received a follow-on design win from another customer, setting the stage for additional orders in the future as this customer expands deployment of our Geode tool to more applications and facilities. Moving to the Q1 of 2022, we expect revenue from our advanced markets to be consistent to slightly down with Q4 levels. Before I hand the call over to Seth, I wanted to note that we continue to expect to close our pending acquisition of Atotech in the Q4 .
Upon closing, MKS will occupy a unique position as a foundational provider of technology solutions across semiconductors, advanced electronics, and an array of attractive specialty industrial applications. The majority of applications in these markets are targeted at addressing the long-term trends of miniaturization and complexity in enabling advanced electronics. Our integration planning activities are on track to ensure that we are fully ready to hit the ground running once we close. In the meantime, as we continue to interact with the world-class employees at Atotech, we're even more excited about the opportunities that lie ahead for Atotech's electronics and general metal finishing businesses, and we look forward to welcoming the Atotech team to the MKS family. Now, I'd like to turn the call over to Seth.
Thank you, John. MKS capped another record year of revenue and profitability despite the well-known global challenges John discussed earlier. These results are both a reflection of the strong secular tailwinds MKS has levered to across our semiconductor and advanced markets, as well as a result of the hard work, talent, and dedication of our global employees. While financial performance in 2021 was exceptional, we're excited to build upon a strong foundation with our pending acquisition of Atotech, which will accelerate our strategy of delivering an even more comprehensive set of technology solutions in the era of miniaturization and complexity. I'll discuss our Q4 and full-year results and provide additional detail and guidance for the Q1 of 2022. Starting with the Q4 sales were a record $764 million, up 16% year-over-year and up 3% sequentially.
Q4 sales to the semiconductor market set another record at $495 million, up 26% year-over-year and up 1% sequentially, reflecting broad-based demand across our portfolio and the strong execution of our world-class operations team. In the past earnings calls, we discussed our breadth and unique exposure to all major semiconductor manufacturing processes, and our Q4 results reflected that diversity. Not only did sales of our vacuum subsystems to semiconductor customers grow 19% year-over-year, but sales of our photonic solutions portfolio grew organically more than 50% year-over-year and grew 90% year-over-year with our Photon Control acquisition. We continue to execute on our strategy to gain share with key lithography, metrology, and inspection customers.
Our photonic sales to the semiconductor market exited 2021 at well over a $300 million annual run rate. We continue to progress on additional design win opportunities. Q4 sales to our advanced markets were $269 million, up 1% year-over-year and up 6% sequentially. We saw a recovery in revenue from industrial applications and delivered strong sequential growth in sales to advanced electronics applications, such as PCB cutting and IC substrate drilling, more than offset seasonally muted flexible PCB via drilling system, systems demand. As John noted, we see an encouraging follow-on demand for our HDI solution from customers that have previously installed a Geode tool in high-volume manufacturing applications. We believe our success in deploying our HDI tool to high-volume environments is a clear indication of market acceptance.
Once the Atotech transaction closes, we focus on leveraging our combined expertise in the HDI market to accelerate our customers' roadmaps and reduce their critical time to market. For the Q4 , the revenue split between our semiconductor and advanced markets was 65% and 35%, respectively. Q4 gross margin was 46.4%, which exceeded the midpoint of our guidance by 40 basis points and grew 70 basis points year-over-year. Our gross margin performance, which includes previously anticipated increases in input costs, is a reflection of our strong operational execution and broad-based ongoing initiatives to continue to drive margin expansion through our long-standing profit and cash recovery program, which we discussed in our Analyst Day in December 2020. Q4 operating expenses, $447 million, slightly down sequentially at the low end of our guidance range.
Q4 operating margin was 27.1%, flat sequentially, and up 240 basis points year-over-year, reflecting effective cost control and strong operating leverage in our financial model. Adjusted EBITDA in the Q4 was $228 million, resulting in adjusted EBITDA margin of 30%. Net interest expense for the Q4 was $6 million, and our non-GAAP tax rate was approximately 16%. Net earnings for the Q4 were $168 million, or $3.02 per diluted share. In terms of working capital, days sales outstanding were 53 days in the Q4 , compared to 54 days at the end of the Q3 . Inventory turns were 2.8 times in the Q4 , compared to 2.9 turns in the Q3 .
Operating cash flow for the Q4 w as a record $194 million, and free cash flow was also a record at $171 million. In the Q4 , we made a dividend payment of $12 million, or $0.22 per share. Actually, in the Q4 we maintained a strong balance sheet and liquidity position with cash and short-term investments at a record over $1 billion, which well positions us ahead of the pending Atotech acquisition. Our term loan principal balance was $824 million at the end of the Q4 . We exited the quarter with a $218 million net cash balance. Moving on to full year 2021 results. Sales were a record $2.9 billion, up 27% year-over-year.
Building on a record 2020 year, semiconductor sales for 2021 were up 32% to a record $1.8 billion, with broad-based strength across our vacuum and photonics portfolios. Advanced market sales were up 19% to a record $1.1 billion. Growth was led by strong results in advanced electronics applications, where we're well-positioned with an extensive array of lasers, optics, motion, and via drilling systems, serving PCB, solar, display, and electronics components applications. As we highlighted at Analyst Day, we expect advanced electronics applications to be a long-term growth driver for our advanced markets, given the increased need for advanced laser-based manufacturing processes to solve for miniaturization and complexity in electronics. That's exactly what we experienced in 2021.
Moreover, we also experienced growth in our other advanced market applications, such as industrial, life and health science, and research and defense. In 2021, the revenue split between our semiconductor and advanced markets was 62% and 38%, respectively. Gross margin was 46.8%, up 160 basis points from 2020. Operating margin was 27%, up 440 basis points from 2020. Our incremental gross and operating margins for 2021 were 53% and 43%, respectively, exceeding the long-term financial model we outlined at our Analyst Day. This strong operating leverage was achieved despite the global supply chain challenges and cost inflation we are experiencing.
Net earnings were a record $634 million, or $11.38 per diluted share, both of which grew at twice the rate of our revenue growth. For 2021, operating cash flow was a record $640 million, and free cash flow was a record $553 million. As John mentioned, Atotech integration activities are progressing very well, and funding the financing will coincide with the close of the acquisition. Until then, the financing remains subject to customary ticking fees. I'll now turn to our Q1 outlook, which excludes any contribution from Atotech. We estimate Q1 revenue at $750 million ± $30 million. This estimate includes the headwinds of industry-wide supply chain constraints, which we expect to persist through the Q1 .
However, overall demand trends are expected to remain strong. We estimate Q1 gross margin of 45%, ±1 percentage point.
The primary driver behind the sequential decline in gross margin is higher cost inflation associated with supply chain constraints. We estimate operating expenses of $153 million ±$4 million. Q1 interest expense expected to be approximately $6 million, and our tax rate we expect to be 19%. Given these assumptions, we expect our Q1 net earnings of $2.57 per diluted share ±$0.25. I'd like to now turn the call back to the operator for Q&A.
Ladies and gentlemen, if you have a question or a comment at this time, please press the star, then the one key on your touchtone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. We also ask that you limit yourself to one question and one follow-up. Our first question comes from Krish Sankar with Cowen and Company.
Hi, this is Steven on behalf of Krish. Thank you for taking my questions. Yeah, first question, if I could, on the advanced markets. So just in terms of the commentary regarding the sequential trends there for the March quarter, sounds like it's consistent to down slightly sequentially. Just curious, like, is that more a function of supply constraints, or is there some downward trends in the end markets that you guys are playing in describing that? Also within it, is China, in terms of geographically, a strong influence on that sequential trend this quarter?
Hey, Steven, it's John. Thanks for the question. You know, we have supply constraints, for sure that are affecting our semiconductor market, but also advanced markets, similar kinds of, components. That's part of it. A little part of it also is the, kind of less visibility that we have in Q1 on some of our advanced markets, businesses. In general, the demand, for those kinds of products in our advanced markets remains very strong, actually. It's really about constraints and a little bit of uncertainty on our customer standpoint. As we said in our, prepared script, when that visibility, changes, and it will, we'll be in a very good position to deliver on that very quickly.
Okay. Got it. Thanks. For my follow-up, just in terms of the component constraints, just wondering if you could offer any additional color on the type of components that might be affecting both your semis markets and also advanced markets supply chain. Is it the same type of semis or other hardware components across the last 90 days, or is the choke point like sort of switching between different components as time goes on?
Yeah, Steven, it's very similar to what we've said in the past. It's still the kinds of electronic components that are, you know, kind of from legacy fabs, so it's really not necessarily the most advanced types of electronic components. These components are shared in multiple industries, and that's where we're seeing the constraints. No change really from the past.
Okay. Is it the same type of components across both, for example, like photonics products, as well as, semis products and advanced electronics?
Yeah, they are similar because, you know, all kinds of products, either in our photonics portfolio or our semi portfolio, you usually have controllers and, you know, PCB boards with electronic components on it.
Okay. Got it. Thank you. Nice job in navigating the current environment.
Thanks, Steven.
Our next question comes from Tom Diffely with D.A. Davidson.
Yeah, good morning. Thanks for the question. Maybe, John, one more question on the supply chain. It sounds like it's kind of just, you know, remains in this whack-a-mole situation, and you haven't necessarily seen it deteriorate over the last quarter?
Yeah, that's a perfect description, Tom. Whack-a-mole. You know, once we fix one particular issue, another one pops up. I think we're all getting better at handling it, but the rate of surprises continues, and I would characterize it as kind of very similar to what we've seen in the past several quarters.
Okay, great. Seth, what are you seeing on the, you know, for your own internal inventory levels of some of these components? Has it gotten a little bit slimmer over the last few quarters, or are you still kind of at a good inventory level?
Yeah. Thanks. Good morning, Tom. I would say inventory levels in total obviously are up, leaning into the higher production volumes. As we mentioned in the prepared remarks, the overall demand across all of our portfolios are really strong, so we're very pleased about that. I really can't comment on individual components in our inventory. I just don't have the data in front of me, but I think it's safe to say that the components that we are working on to bring in to the operating facilities are probably lean on the inventory side as well. It's just natural. It's gonna happen.
Yeah.
As John mentioned, you know, the team's doing a great job. We've got a real strong operational team. I think we saw some of the supply chain constraints later than some of our peer groups, is our impression, so I think it's a testament to how we've managed this historically speaking. We have a lot of comps we'll work with this, you know, through 2022 as well, the global, you know, effect that we're working through. You know, we're pretty optimistic we'll eventually, you know, pull out of this.
Great. Okay. John, sounds like some nice momentum on the HDI tool. Is there a certain market inflection that we're looking for before those turn into real volume production?
No, Tom, I think that market continues to drive a roadmap to smaller features, to higher density of features to even new materials. That really hasn't changed. Our tool is prepared and has been demonstrated they can you know, address all those types of challenges going forward. We're really happy with, you know, we've had tens of tools running in high volume manufacturing with two major customers. One's been running for nine months, one's been running for 12 months. These tools are delivering revenue as we speak to those customers. Then we talked about a couple more design wins, one of which was for another high-volume customer that, you know, we're well set up for future orders.
I think that's really a testament to the fact that the tool we have is really capable to run in high volume manufacturing. We're really pleased with the progress we've made so far.
Great. Final question. John, when you look at the just the semi cap market, the wafer fab equipment market, do you agree with the $100 billion estimate for this year and perhaps a second half ramp?
You know, it's tough to say. I would say, Tom, that we're always ready for incremental increases and demands from our customers. As you know, we have our factories very lean and capable of ramping with surge capacity. We're always able to do that. You know, in 2021, of course, it was kind of a $85 billion-$90 billion WFE, and we did pretty well. We believe we gained share in certain product lines as well. We're ready for, you know, the higher WFE that some folks have predicted in that range or higher.
Great. Well, thank you both for your time today.
Thanks, Tom.
Our next question comes from Patrick Ho with Stifel.
Thank you very much. John, maybe just following up, another supply chain question for you. Can you just give a little color, is it primarily components and parts shortages that you're experiencing, or is it a mix of different things, you know, higher input freight costs, workforce reductions within your supplier base? Can you just give a little bit of color of, I guess, the different variables that are impacting you in the near term?
Yeah, yeah, sure, Patrick. I think, you know, in terms of freight costs, that hasn't really materially gotten worse. It's not great, of course. It's been there and still there. In terms of workforce effects of our suppliers, it really was, you know, much worse in the early part of 2021, you know, with the Malaysia shutdown. Recently, that's really not been that big of an issue. It's really just demand outstripping supply for those electronic components that's really causing us the, you know, the headaches today.
Great. That's helpful. Maybe as my follow-up question also for you, John, in terms of some of the opportunities on the RF power side, in the conductor etch market, are you leveraging the relationships and the wins you've had on the dielectric etch to further penetrate into the conductor etch market, or are some of these quote new opportunities?
I would characterize it as, you know, we have had long-term relationships with all the major semiconductor OEMs, and our dielectric etch market share is leading, as you know. That relationship has been there. Those relationships have been there for decades. You know, when they need a conductor etch supplier and a solution, that's really when we came in and got those few design wins that we talked about a few years ago, that we are now seeing the ramps with those design wins.
Great. Thank you very much.
Thanks, Patrick.
Our next question comes from Sidney Ho with Deutsche Bank.
Hi, this is Jeff Rand for Sid. While still very strong, your semis market likely undergrew WFE in 2021, and historically, your growth versus WFE will vary based on where we are in the cycle. Do you think this lower growth this time reflects where we are in the cycle, or is it more of a reflection of the supply chain environment?
Yeah, Jeff, thanks for the question. Really, it's probably where we are in the cycle mostly. You're right, we were about the same growth rate as WFE, maybe a little less in 2021. As you know, we front run the ramp, and so our 2020 growth rate was 50%, which certainly was a lot higher than WFE. We always look at it in the long term. If you just even take the last two years, 2021 and 2020, we outgrew WFE by 700 basis points. We're still very happy and confident with our model, which is the 200 basis points above WFE for the long term.
Great. As my follow-up, how should we be thinking about the trajectory of operating expenses as we go through calendar year 2022? I would assume you'll see an uptick in travel and labor costs, but also perhaps a decline in some COVID safety costs.
Yeah, Jeff, this is Seth. Thanks for the question. Yeah, we guided in Q1 $153 million, you know, ±$4 million. I think you'll see our expectations go a little bit in Q2 and probably level out. Probably $160 million range, sort of, you know, Q2 and thereafter is a kind of good way of thinking about it, is how we looked at it. That's kind of what I would use for modeling purposes.
Great. Thank you.
Yep. Thanks, Jeff.
Thanks, Jeff.
Our next question comes from Paretosh Misra with Berenberg.
Good morning. Thanks for taking my question. In the semis market, it sounds like you expect sales to be flat or slightly down in Q1. Is there any major product line in your semis portfolio where you think sales might be sequentially up, or is that pretty much kind of same view across the board?
Paretosh, you know, we have a very, very broad portfolio, and quarter to quarter by product category, it can vary. Even if the entire semiconductor revenue is, you know, flat to slightly down, there can be products that would exceed that. You know, I would point out RF power that we talked about in the script. You know, in 2021, I think we grew in high 30% year-over-year growth rate. Of course, that's a great growth rate for the year, shows our leadership in dielectric etch, our incremental growth in conductor etch, and the fact that 3D NAND is ramping as well has helped. You know, certain product categories could continue to grow and outgrow the average.
Got it. In terms of how you guys are managing inflation, on the component and logistics side, are you announcing price hikes? Is there, depending on, I guess, the product, is there anything that would maybe kick in at the start of the calendar year, that we should be thinking about in terms of price increase?
Yeah, Paretosh, we have, as you know, a profit and cash approach, that's something we do all the time, every day. We're always looking for ways to make ourselves more efficient, ways to make sure that we're getting fair value for and fair price for the value we bring. There's no, you know, step increment of activity. That's something we do all the time. We are continuing to do that. We still continue to lean in, especially since the input costs are going up. You know, that's something we do all the time.
Understood. If I could ask just one more. In the pressure measurement business, I believe you mentioned it was a new record, quarterly record. Is there any other color you could provide in terms of where or how much revenues you're generating in that business?
Well, you know, as pressure measurement, as you know, is. We're market leader there. We're really happy with its performance. I would say that that's one of those product categories that's outgrown the average when you look at our semiconductors revenue. That's saying something because when you're the leader in market share on that kind of particular category, it's really, you know, incrementally more difficult to grow market share, but we have. We're really pleased with how the pressure team has performed.
That's useful. Thanks, John, and good luck with everything.
Thanks, Paretosh.
Our next question comes from Joe Quatrochi with Wells Fargo.
Yeah, thanks for taking the question. I was hoping you could help us kind of maybe understand the component availability in semis. You know, I think you know, on a sequential basis at least, you know, within your Light & Motion business was up sequentially while the Vacuum & Analysis business was at least from a semis perspective, down sequentially. You know, are you seeing a difference in component availability just given the different bill of materials there or just any sort of detail would be helpful.
Yeah, Joe, thanks for the question. You know, I think that we characterize it as the differences between photonics types of products and vacuum-based types of products. Photonics-based products have, you know, a little less electronic components to them, you know, in our subsystems versus the vacuum chamber types of subsystems. If there are, you know, a plethora of electronic component shortages, certainly would affect our Vacuum & Analysis type of products more than our photonics products. That's what we're seeing. It's affecting both sides now, it's certainly a little more bigger effect on the Vacuum & Analysis types of critical subsystem products.
Got it. That's helpful. Then, you know, you talked about having, you know, the manufacturing capacity to support, you know, this $100 billion WFE this year. Curious, you know, what about your suppliers, maybe thinking outside of the kind of component constraints right now, but how do you think about your suppliers' manufacturing capacity to support, you know, you supporting $100 billion WFE? Do you need to bring on additional suppliers to do that?
Great question, Joe. We have been throughout you know the last six quarters bringing on new suppliers, working with current suppliers to expand their capacity, and they have done a great job doing that. I think really, it's really their ability to get those components. It's really not their capacity, it's really just getting the actual electronic components so they can you know build them into their factories. It's not done. It's continuously you know something we have to watch and work with our suppliers on. That's really not been a major part of the constraints, just actually getting those electronic components. It's really our suppliers in effect.
Got it. Very helpful. Thank you.
Thanks, Joe.
Our next question comes from Mark Miller with Benchmark Company.
Congrats on your record quarter. You've been talking about supply constraints, but what about supply constraints at your major customers? Is that also impacting you in terms of, you know, reduced orders?
Thanks for the question, Mark. No, our major customers, and I think it's true across the industry, continue to order at record levels, as we talked about. Demand is not the problem. I think as some other folks have said, the visibility of demand is going out further and further than we've ever seen before as an industry. That's not been the constraint at all. Even though these supply constraints are affecting the entire industry, it's not affecting how they're planning and how they're ordering.
Okay. What can you tell me about factory utilization? Is that high? Do you still have some room to expand if you need it?
Yeah, it's a great question. I think when COVID hit and supply chain constraints continued to be challenging, certainly, you know, is a headwind on our factory utilization, but that has been improving actually, quarter-over-quarter. Really utilization has gotten a lot better. You know, the degradation in gross margin is really about input costs, not about our utilization.
Thank you.
Thanks, Mark.
It looks like there are no further questions. I'd like to turn the call back to David Ryzhik for any closing remarks.
Thank you for joining us today and for your interest in MKS. Operator, you may close the call, please.
Ladies and gentlemen, this concludes today's presentation. You may now disconnect and have a wonderful day.
