Good day, everyone, and welcome to Integra's Second Quarter 2021 Earnings Release Call. Today's call is being recorded. At this time, for opening remarks and introductions, I would like to turn the call over to Bill Seymour, VP of Investor Relations. Please go ahead, sir.
Good morning, everyone. Earlier today, we announced the financial results for our Q2 of 2021. Before we begin, I would like to remind listeners that our comments today will include some forward looking statements. These statements involve a number of risks and uncertainties, and actual results could differ materially from those projected in the forward looking statements. Additional information regarding these risks and uncertainties is contained in our most recent annual report and subsequent quarterly reports that we have filed with the SEC.
Please refer to the information on the disclaimer slide in the presentation. On this call, we will also refer to non GAAP financial measures as defined by the SEC and Regulation G. You can find a reconciliation table on today's news release as well as on our IR page of our website at integris.com. On the call today are Bertrand Lalois, our CEO and Greg Graves, our CFO. With that, I'll hand the call over to Bertrand.
Thank you, Bill, and good morning to all. We are very pleased with our Q2 performance, and I want to Start by recognizing the phenomenal job done by our manufacturing and supply chain teams. During the quarter, sales grew 27% year on year and 11% sequentially. Our growth was strong across all three divisions As we benefited from robust industry conditions and increasing demand for our products and solutions, We experienced strong flow through on our sales and margins improved nicely, leading to Record operating income and EBITDA for the quarter. In addition, non GAAP EPS was up 42% year over year And 21% sequentially.
Let me provide a little bit more color on our revenue performance. From a product standpoint, we continue to benefit from the growing demand for our leading unit driven solutions, especially in strategic areas like liquid filtration, which is up 24% year to date And Advanced Deposition Materials, which is up 28% year to date. Another highlight of the quarter was obviously Our CapEx driven product lines, which are following the trend of a robust industry CapEx. Growth was especially strong in the fluid handling, wafer handling and gas purification product lines, which in the aggregate Grew 37% in the first half. In addition, our Alamus High purity bags, which are used for COVID-nineteen vaccines worldwide, recorded stronger sales than planned.
We now expect that RMS sales will reach approximately $50,000,000 this year. It is also worth noting that The unique characteristics of the Aramis Bag, specifically high purity and high structural integrity, All of increasing interest for use in other non COVID biologics. I am also very pleased to share that During the quarter, we made an additional $3,000,000 contribution to the Entegris Foundation, which funds STEM Scholarships for women and individuals of underrepresented communities. The first round of these scholarships were awarded for the upcoming school year. During the first half of this year, we achieved organic growth of approximately 25%, impressive considering the various production and supply chain constraints the industry and Entegris Our manufacturing and supply chain teams have done an amazing job and have been instrumental in delivering these great results.
However, in this constrained industry environment, every day is a battle and likely will be for a while. That said, we remain confident about our execution going forward. On that note, last quarter, we outlined 3 main issues we've been addressing, and I'm pleased to report that we've made solid progress. The first area was labor constraints in some of our U. S.
Manufacturing locations. During Q2, We were able to alleviate most of that pressure by adding production headcount and by moving many of our operations to a 20 fourseven work schedule. In addition, we expect to bring new production equipment online in Q3, which will bring additional capacity to certain critical product lines. The last This area relates to industry freight capacity and component availability, and we expect these constraints to ease as we progress through the second half of this year. Looking at the full year, our outlook for the industry and Entegris Has improved again.
The semi market looks increasingly strong across the logic, memory and mainstream segments, driven by improving demand trends in areas like mobile phones, high performance computing, IoT and Auto. For the full year 2021, we now expect the market based on our unit CapEx Mix will be approximately up 17% compared to our previous expectation of up and our order book continues to be at a record level. As a result, we expect to outperform the market and now expect our sales growth for the full year 2021 to range from 21% to 22%, compared to our previous expectation of up 17% to 19%. Finally, we expect the EBITDA flow through to be in line with our target model and now Expect full year 2021 non GAAP EPS to exceed $3.30 which is starting to approach the 2023 EPS target of greater than $3.55 which we communicated in our Analyst Day last year. Looking further ahead, the long term Fundamentals of the semiconductor market are very encouraging.
Positive secular demand trends have become increasingly evident, driven by accelerated digitalization, 5 gs and high performance computing to name just a few. In addition, the pace of node transitions for both logic and memory has quickened in recent years and device architectures are becoming Much more complex. This is great news for Entegris because the unique set of capabilities we have built Around Process Materials and Materials Purity will be the key enablers of these new chip architectures. And this will translate into our rapidly expanding served market and increasing Entegris content for wafer. And with 70% of our revenue, unit driven or recurring in nature, we expect our business model to be more resilient across cycles as it has proven to be the case over the past decade.
Finally, I want to take a moment to thank our customers for the trust and confidence Thank you. And once again, thank the Entegris teams around the world for their incredible work. Now let me turn the call to Greg. Greg?
Thank you, Bertrand, and good morning, everyone. I also want to recognize the great work of the broader Entegris team for delivering a record quarter in what continues to be a dynamic environment. Our sales in Q2 were $571,000,000 up 27% year over year and up 11% sequentially. GAAP and non GAAP gross margin were both 46.4%. Gross margin was essentially in line with our guidance as higher volumes were slightly offset by the negative impact of mix.
We expect gross margin to be approximately 47%, both on a GAAP and non GAAP basis in Q3. And we continue to expect gross margin will be approximately 46 point 5 percent for all of 2021. GAAP operating expenses were $126,000,000 in Q2 and included $13,000,000 of non GAAP items from amortization of intangible assets, integration and other costs. Non GAAP operating expenses in Q2 were $114,000,000 OpEx was above our guidance range, but lower as a percentage of sales both year over year and sequentially. OpEx for the quarter included the $3,000,000 discretionary contribution made to the Integris Foundation that Bertrand previously referenced.
We expect GAAP operating expenses to be approximately $129,000,000 to $131,000,000 in Q3. We expect non GAAP operating expenses to be approximately 100 and at $16,000,000 to $118,000,000 Q2 GAAP operating income was $139,000,000 Non GAAP operating income was $152,000,000 or 27 percent of revenue, up significantly both year on year and Adjusted EBITDA was approximately $174,000,000 and exceeded 30% of revenue. Moving to below the operating line. Our GAAP tax rate was 15% and our non GAAP tax rate was 17% for For Q3, we expect both our GAAP and non GAAP tax rates to be approximately 19%. For the full year 2021, we continue to expect both our GAAP and non GAAP tax rate to be approximately 18%.
Q2 GAAP diluted EPS was $0.65 per share. Non GAAP EPS of $0.85 per share Was up 42% year over year and 21% sequentially. Turning to our performance by division. Q2 sales of $180,000,000 for SCEM were up 23% year over year and up 8% sequentially. Growth was primarily driven by Specialty Gases, Advanced Deposition Materials and Advanced Coatings.
Adjusted operating margin for SCEM was 25% for the quarter, up 400 basis points sequentially. The increase in operating margin was primarily related to higher sales volume and a benefit from the sale of some non core intellectual property. Q2 sales of $228,000,000 for MC were up 24% from last year and up 10% sequentially. MC has performed very well across all product lines so far this year With growth especially strong in liquid filtration and gas microcontamination. Adjusted operating margin for MC Was 34% for the quarter.
Q2 sales of $173,000,000 for AMH We're up 36% versus last year and up 16% sequentially. It's worth noting that AMH has the greatest exposure to industry capital spending and this was evident in very strong sales of wafer handling and fluid handling products. As Bertrand referenced, sales of our Aramis high purity bags continue to be very strong. Adjusted operating margin for AMH was 24%, up significantly both year over year and sequentially. The margin increase was primarily driven by the higher sales volume.
2nd quarter cash flow from operations was We continue to expect to spend approximately $225,000,000 in CapEx this year. Consistent with our capital allocation strategy, during Q2, we used approximately $11,000,000 for our quarterly dividend And we repurchased 15,000,000 of our shares. Now for our Q3 outlook. We expect sales to range from $575,000,000 to $590,000,000 We expect GAAP EPS to be 0.76 to $0.81 per share and non GAAP EPS to be $0.84 to $0.89 per share. In summary, we continue to execute very well even in the midst of a dynamic supply chain environment.
We continue to demonstrate the leverage in our unit driven business model. Operator, we'll now open up for questions.
Thank We'll now take our first question from Toshiya Hari from Goldman Sachs. Please go ahead.
Hi, guys. Good morning and thanks so much for taking the question and congrats on the strong results. Bertrand, I had, I guess, 2 questions and one quick clarification for Greg. First of all, in terms of the big revenue beat in Q2, obviously, it was a very strong beat within the context Your company's history, I feel like you've come in towards the high end, sometimes above the high end, but this was above and beyond what many of us So was this kind of conservatism in hindsight or was it better supply, better operations internally? What drove the significant revenue beat in Q2?
And then for the full year, you're raising your market forecast from 2013 to 14 to 2017. It would be helpful if you could differentiate between, how you're thinking about CapEx And then I've got a quick follow-up. Thank you.
Sure. Yes, good morning, Toshiya. Let me start with your question on Q2. I mean, the short answer to your question is that we were indeed probably a bit too I mean, we expected very strong demand for our products going into Q2, and we saw Just that across the board, so no real surprise here. But on the flip side of that, we experienced a very Severe supply issues in Q1 and we were probably a little bit too conservative as
a result of that in our forecast for Q2.
And as I mentioned in my The teams have done a phenomenal job in Q2, exceeding our expectations, moving mountains To secure supply lines, to increase output in Q2 and our results in Q2 really show that. When it comes to your second question on the annual guidance, I think The industry has continued to strengthen through the quarter, right? And it is clear that We are expecting at this point all fabs to operate at full capacity for the balance of the year. And the capacity plans of all of our customers have also firmed up and being confirmed. So right now, the way you get to that blend of 17% for the full year is wafer stocks up About 14% and CapEx slightly in excess of 25%.
And again, CapEx For us, it's really the full industry CapEx as opposed to WFE. And you said you had a follow-up question,
I do. Thank you. I guess around EUV, clearly there seems to be very strong momentum In terms of adoption of the technology, the Big Logic company here in the U. S. Seems to be accelerating its efforts.
All 3 DRAM companies at this point seem to be on board as it relates to technology. So I guess my question is, If you can kind of rewind the clock and sort of speak to what you've seen in the foundry space as it relates to EUV, how that's benefited your business And what your expectations are going forward as it relates to the EUV ecosystem, That would be super helpful. And then one last quick clarification for Greg. You talked about selling non core IP And SCM, if you can quantify the positive impact from that in the quarter from an EBITDA perspective, that would be helpful. Thank you.
Yes. So, Toshi, on EUV, we are indeed very, very excited to see the adoption broadly of this technology. As you know, this is an enabling technology to find features and more complex architectures. And our solution set is really thriving on greater process complexity. The finer the features, The greater the need for very advanced purity in the materials and the chemistries used in the process, So all of that is going to create conditions for greater integrators content for wafer.
And I think it's great to see across Memory and logic, much more ambitious technology roadmaps now with finer features, which Entegris will benefit from. So I think, again, great news. And certainly, 2021 is a breakthrough year for EUV, and that's Very positive for us. I'll turn to Greg to talk a little bit more about the impact of this sale of IP, which relates to Some cleaning chemistries and so go ahead.
Yes. So, Shao, it actually relates Some cleaning chemistries that we acquired the IP for when we or that we acquired as part of the ATMI transaction. We retain the right to use the IP, but it's not IP that we view as meeting on an absolute exclusive basis, so we sold it to another industry participant. That showed up as a, believe it or not, as a credit in the accounting mandate that it show up as a credit in our SG and A line and it benefited the SCEM division. It was low single digit millions.
Helpful. Thank you so much.
We'll now move to our next Question from Sidney Ho from Deutsche Bank. Please go ahead. Your line is open.
Thanks for taking my questions and congratulations on a good quarter. We're trying to address some of this in your prepared remarks, but is there any chance you can quantify what the impact on revenue was for the first half From supply constraint and perhaps what you expect in the second half. But do those missed revenue go to a competitor or do you think they will come back to you
Yes. So let's just say that, I mean, the supply constraint The issue is really a challenge that the entire ecosystem is facing And that includes our competitors as well. So the real solution for us and for our customers is That we increase our capacity as quickly as possible. And that's really what our customers want and need From us, and this is really what we've been very, very focused on. I will not be quantifying the delta Between supply and demand, it is true that we were supply constrained in Q2.
I expect some additional Supply limitation going into Q3, and I would expect most of that to be alleviated as we get into Q4. So Again, the teams are very focused on reducing that gap to the minimum possible. So ask me the question again at the end of the year, and I will tell you if there is a gap left. But again, it's fair to say that As of right now, in Q2 and going into Q3, demand is exceeding supply for us.
Okay, great. I'll ask that question again in 3 months. My second question is, I noticed you don't disclose revenue by region in your I know it's in the SEC filings. So just curious how your revenue into China has been? And can you double click on that and give us a sense that the revenue split between domestic versus multinationals As well as memory versus foundry versus mainstream.
And do you guys see any signs that your customers may be building up some buffer stocks? Thanks.
Yes. So I mean, if you think about the regions, first of all, all regions had Record revenue with growth year on year and sequential growth as well. I think specifically on China, we had a big quarter in China exceeding 60% And it's a function of a number of different factors. I mean, first, remember, the first half of last year was an easy comparison, right? A lot of our customers We're in a very significant slowdown early in the year, last year.
And then as you recall, we had a number of shipments that have been on hold And getting the required export licenses. And I'm pleased to say that we in Q2 of this year, we've been able To get approval on all the necessary licenses to release the holds on our U. S.-made products. So again, so those are two important factors driving the China revenue. And then the last one is that There's been a lot of investment in China over the last 2, 3 years, and a lot of new capacity has been coming online.
And that has been driving, obviously, greater consumption of our consumable profits.
Great. Thank you.
Sure.
We'll now move to our next question from Patrick Ho from Stifel. Please go ahead.
Thank you very much and congrats on the nice quarter and outlook. Bertram, maybe first qualitatively, I know you don't want to give guidance over future But given some of the industry dynamics that we're seeing today, as you mentioned, the strong demand environment, some of the supply constraints that are still there, What's your visibility like, I guess, in both of your units as well as CapEx driven products? Are you getting visibility longer than you typically would. And how does that help you in terms of alleviating some of the supply chain issues that you have?
So Patrick, I think we commented on the visibility in the last Couple of quarters, and I would say that the visibility remains very good and probably better than normal. So that's important, obviously, as we make capacity decisions, as we make Procurement and Planning Decisions as well. And that's really what the team has been very focused on and will continue to be focused on, which is Making sure that we secure access to the right level of supplies, and we've been working very, very closely with our supply chain partners and then making sure that internally we unlock as much New capacity as we can, and we talked about how we were intending to do that in Q2, and it was really mostly about Hiring and training new operators, I think we've made a lot of good progress in Q2, and we are exiting Q2 with Much greater capacity than we started the quarter. And then in Q3, we are counting on a number of new levers With new membrane surface treatment equipment coming online, new Cleaning capacity for our liquid filters coming online, and that's going to benefit our liquid filtration product lines as we get into the And we are also expecting to get new high purity drum capacity in Q3 and that's going to help our AMH division.
So we are very focused on Short term capacity additions, mid term capacity additions. And then, of course, we talked about our longer term Capacity plans with this big investment in Taiwan as well. So we're very, very focused on that. And as you said, it's because we have a high degree of confidence In our growth strategy, short term, but also for many years to come.
Great. That's helpful. And as my follow-up question, you gave a good description on some of the opportunities on EUV. The industry is also progressing forward towards gate all around or formats of that nature. One of your large customers talked about it yesterday.
How do you see the opportunities for Gator around because that is quite materials intensive? Does that provide another impetus for both the SCCM Group and Microcontamination Control? What are some of the incremental opportunities you see there as you start working with your customers on that architecture?
I think your question is right on, Patrick. I mean, We are very excited about what we see on the road map. Those new architectures will be Requiring highly engineered materials that are not used by the industry today And that we are very, very focused on developing with our customers. As you know, those gate all around Factors or features will be introduced at atomic levels in terms of Dimensions, and that's going to require much greater levels of purity throughout the process. So again, a lot of reasons for us to be extremely excited and bullish About our prospects and about the road map and what it will mean in terms of Entegris content per wafer for the years
Great. Thank you.
We'll now move to our next question from Amanda Scarnati from Citi. Please go ahead.
Hi, good morning. The first question I have is sort of on this component constraints that you said might be easing towards the end of the year. Are you seeing any specific issues with sourcing materials? You've been hearing that the chemical supply chain is getting increasingly more tight across the board. Are you seeing any specific issues there?
Or do you expect that to be progressing nicely throughout the rest of the year?
Yes, Amanda, it's a good question. I think that that's one of the reasons why we want to We remain fairly cautious in our outlook simply because I think we have control in But we have less of a control on what our supply chain partners We'll be able to do and again, they are making a lot of very Promising commitments, but again, that's not something that we control directly. So I think that there are many reasons for us to believe that the situation will ease As we progress throughout the year, but that's something that we're going to be obviously very focused on, and we're trying to help our supply partners in any way we can. And I think again, as I was saying, I think that's a reality that is across the ecosystem.
Great. Then as a follow-up, in the Aramis Bags division, you mentioned that you expect this to reach about $50,000,000 this year. Is all of that COVID related? Are you starting
So Amanda, I would say that The revenue we expect to generate in 2021 will be mostly COVID related. The good news, however, is that the opportunity pipeline is Starting to have a slightly different shape with a lot more non COVID related opportunities. So If you take that statement in the context of the recent investment in new capacity, I would say that this capacity will be filled With COVID related opportunities probably for the next 18 to 24 months. And then I would expect a smooth transition to non
Great. Thank you.
Sure.
We'll now move to our next question from David Silver from C. L. King. Please go ahead.
Yes. Hi. Thank you. I had a question my first question would be kind of on the capacity constraints either for yourselves or But firstly, in your opening remarks, you did talk about new additions coming on in the Q3, maybe to relieve some bottlenecks. I was wondering if you might I mean, we there's a number of stories obviously for a long time now about shortage conditions or chip Production being limited by various constraints.
From your planning perspective, I mean, do you believe that The shortage conditions or the near full out operating conditions in the industry, is that Going to last well into 2022 beyond that, maybe be over by the end of the year. How are you kind of planning for The duration of what some people say would be sold out industry conditions amongst chipmakers?
Yes. So, those are really good questions, Broad questions. We could probably spend a lot of time discussing them. I'm going to try to be succinct in my answer. I think When it comes to our capacity improvement plans, I cited a few New initiatives as we get into Q3 impacting positively impacting our Liquid filtration output and positively impacting our high purity drum output, and that's what we're going to be Very focused on working with our customers to qualify those new pieces of equipment or those new production lines.
And as I was mentioning, we're continuing to hire a lot of new operators, train them, move Most of our work centers to 247 work schedules and all of that will have A nice positive impact on our capacity. When it comes to visibility, as I was saying, I think we have a good Visibility for the balance of the year, I think it never really extends Far beyond that, having said that, when we think about 2022, I think all indications are that It should be another positive year for industry. I mean, we expect a lot of new capacity to come online. We expect our fab customers to run more wafers at the leading edge where we have higher Integris content per wafer. I will not quantify those statements.
We will do that in January, February time frame, as we always do when we report earnings for the year and when we guide for the next year. But as we sit today, based on what we are hearing from our customers, we expect
Okay. And I'm going to follow-up that overly broad question with kind of a more targeted one. But I wanted to focus on your AMH segment. It's your Smallest segment, but year over year or sequentially, that was the segment that had shown the strongest growth. And there's certainly some elements in there.
I consider the wafer handling element may be More CapEx driven, potentially lumpy, and then the Aramis portion of the growth is going to be more, I don't know, secular, I guess. But in your Q3 guidance, you've kind of at the midpoint, your revenues are due to be up But I'm just wondering about your anticipated contribution from your AMH segment. In other words, will that Potentially lumpy contribution on wafer handling and maybe some other products there continue or is this the case where Some of that lumpiness may recede for the balance of the year.
Thank you. I can start and then Greg maybe can add to that. But in terms of the revenue performance of AMH, As you mentioned, remember that this is the one division that has the most exposure to CapEx. So as you would expect in that context, growth was particularly strong in our CapEx driven So product lines like FOUP, Fluid Handling Solutions, Sensing and Control. But frankly, we also saw strength in our wafer shipping business, which is more of a unit driven business for them.
Even in the smaller diameter, 200 millimeter fabs are producing at very, very high levels right now, and that's benefiting Some older generation products and of course we've talked about the positive impact of our RMS bag So I think that the performance for AMH, which is up 32% year to date. I would expect actually that level of performance on an annual basis. Again, mostly because of the strength in the industry CapEx and the positive impact of the Aramis Banks. And then on the bottom line, I think Greg, I don't know if there's anything you want to add to that?
No, I would just say, David, you'd asked about, as it relates So our guidance, I mean, we would expect that business to be up slightly similar to the overall broad based guidance. Bertrand mentioned some areas where the business has performed well. He also mentioned early in the call EUV. The EUV part of that business has done Quite well. And then profitability, that team has executed well, but it's also our business probably with the highest, I'll call it, fixed cost leverage, Both on the cost of goods sold line as well as operating leverage because they've got a relatively Relative to the other two divisions, lower much lower ER and D spend.
And so that you're seeing that leverage, you can see those Margins in 24% range like we saw in the most recent quarter.
Very good. Thanks very much. Appreciate it.
We'll now move to our next question from Paretosh Misraff from Berenberg. Please go ahead.
Thanks and good morning. Can you talk about your growth that you saw in the logic versus memory in the first half of this year? And any Color any expectation that you have for the second half in terms of which of these you think will be the bigger growth driver in the second half?
Yes. So, Paretosh, I mean, if you think about LogicFoundry, all fabs are really running at Full capacity right now, and we're seeing obviously a lot more wafers being produced at 10 nanometer and below. That's good for us. Year to date, that particular set of customers is growing in the mid teens, And we would expect that growth rate to increase in the back end of the year because there will be new capacity at the leading edge that is expected to come online And that's going to actually create favorable conditions for a pickup in revenue in liquid filtration and deposition materials And surface prep, chemistries as well. So again, good performance year to date, But I think that I would expect an acceleration in the back end of the year.
Got it. Thanks. That's useful. And then With regard to the SCN business, can you just maybe provide a little bit more color on your mix in this quarter? And Was the mix a tailwind for margins on a sequential basis or a year over year basis?
Do you want to take that, Greg, if you want me to? Sure.
I'll take it. Yes.
So within the
SCEM Business, I mean, mix was slightly positive. It was not a significant factor. I mentioned in the prepared remarks, the margin did benefit from an IP sale which had a Several basis point impact on that operating margin for the most recent quarter, But I'd say the mix was generally consistent with what we've been seeing.
Got it. Got it. Thanks. And my last question is on your filtration business. Do you Also sell your filtration microcontamination products to other chemicals companies just to help them Purify their products and if yes, then any way you could quantify as to what percentage of sales go through those channels?
So yes, the short answer is yes. We are selling bulk filters To a broad array of chemical manufacturers, examples of products would be photoresist, Obviously, but also IPA and all sorts of different chemistries used in In the manufacturing process of semiconductors, this is a segment that has been growing very fast and is growing in importance For us, because the degree of purity required in bulk chemicals It is becoming increasingly more stringent and that has opened up opportunities not just for our liquid filters, But also increasingly for our high quality drums. We don't disclose and we don't intend to disclose those types Of market statements, so market segments. So I don't really intend to break that down for you today, but I would say This is certainly a big area of growth for us.
Thanks for that. Thanks Bertrand. That's all I had. Thank you.
Sure. Thank you.
We'll now move on to our next question from Chris Kapsch from Loop Capital Markets. Please go ahead.
Yes. Hi, good morning. And kudos to you and your team on execution. I was hoping you might be able to To characterize your continued outperformance relative to the industry, let's say, I guess, maybe into the second half of this year or into next year. And if excluding the effect of the Aramis bags, do you see the outperformance being more pronounced in equipment
And for the nice comment, I would say that if you think about the Aramis product line, it's contributing a soft 2% of growth year to date. I think it will contribute a stronger or a full 2 point of growth on an annual So the rest of the outperformance is in fact mostly unit driven. And I think I gave you some clues In my preliminary remarks, citing in particular, deposition materials growing at 28 which is about twice the rate of wafer starts or also mentioning our liquid filters Growing at about, I think it's 21%, 24% year to date. So Again, 2 very important product lines. Recall that those are areas where we have invested a lot in R and D over the past years.
So it was important for us to see the results, and we are seeing results, frankly, that are exceeding our expectations
That's helpful. And actually, the follow-up was on that metric you gave on advanced deposition materials, The 28% growth. I'm curious about if you could get more granular on that in terms of logic versus memory. I think you said advanced logic sales were up mid teens, so maybe that was part of the answer. But was this strong growth in advanced deposition, was it More a function of ramping nodes in logicfoundry or is it really most pronounced in the migration within the memory sector
So this year, it has been Mostly a memory story. Remember that a lot of our customers have transitioned now to 128 layers and some of them have been transitioning to 176 layers And all of them are actually taking steps to transition to 200 plus layers going into 2022. So With those transitions, we saw a number of new opportunities for deposition materials opening up. We saw new opportunities for selective etching chemistries as well. And those are The trends that have been driving our SCEM business, so it's mostly memory this year.
I would expect Logic to play a bigger role in the next years as some of those new molecules are With memory continuing to drive SCM growth in 2021 2022.
Very helpful color. Thank you.
We'll now move to our next question from Timothy Arcuri Lurie from UBS, please go ahead.
Thanks a lot. I had two questions. Bertrand, first for I know you're talking to customers all the time. And do you see any signs of them stockpiling inventory of your products At customers, I know we've heard more of that happening during the Q2. I'm just wondering if you can sort of handicap whether or not you think this is happening?
So Tim, it's a fair question, something we're constantly looking at, especially in the very, very sharp ramps And especially at a time when we are capacity constrained, so obviously, something that we are paying very, very close attention to. I think there may be a little bit of that in China for the reasons that we all But putting China aside, I think that the demand for our products are really driven by the very, very strong level of Fab activity right now. If I mean, do you I don't know about you, but I mean, we've It's hard to find electronics. I will give you just an anecdote, but I think it's telling. I mean, we've been hiring a lot of new members They are running at very, very low levels of inventory for their finished products.
And in many cases, For the Entegris products, for their raw materials, they claim to be below what would be their normal Inventory levels. So I think that right now, This is not a risk and I don't think that there is really a lot of excess inventory in the channels. I don't think there is any. I think we are below normal levels.
Got it. Got it. Okay. Thank you. Thank you for that.
And I guess, Greg, for you, I I guess I had a question on gross margin drop through. I mean, you did a great, great job in June, don't get me wrong, But the margins came in line and if I look at the gross margin drop through over the past 3 years, you've done 50% more revenue and the gross margins basically Hasn't really changed much over that period. So I'm just wondering what can change to make the drop through a bit better? I know you've been investing in capacity, but Also, we should see some leading edge wafer addition and that should help gross margin, I would think, as well due to mix. So Can you just talk about the drop through and should it get better going forward?
Thanks.
Yes. So First of all, I mean, on the gross margin in the most recent quarter, As I said in the prepared remarks, really, I mean, the higher volumes were offset by the negative impact of mix and that emanates So primarily in the MC business. With regard to sort of the longer term trends, I mean, if you look over the last several years, our capital Spending has been up pretty significantly as we add capacity and we add capability. We'll continue to do that. What I would say is I would expect the margin to have an upward bias, but I've always said, I mean, think of this as a business where Do I think we can do 47, 48 type margins?
Yes. But I don't think long term this is a business where you're going to see margins in the 50s. I wish I could say it differently, but I mean, I've watched and you're highlighting it. I mean, we watched Over a long period of time, I mean, I think our customers are going to let us have margins where they are, maybe slightly above where we are.
Okay. Yes, great. Thank you.
We'll now take our final question from Mike Harrison from Seaport Research Partners. Please go ahead.
Hi, good morning. So Bertrand, we've talked a little bit about the Supply and demand tightness and your view that demand is outstripping supply right now and we're in this broadly inflationary environment. So are you seeing that your pricing is increasing at all as a component of The revenue growth you're seeing either in response to inflation or as a result of this tight supply demand environment?
So look, I think we are obviously watching all of those Trends and we're going to continue to adjust our strategies to mitigate Potentially negative factors to a margin. I don't think we want to go into the details of Our mitigation strategies or pricing strategies on this call, but the punch line, as Greg was mentioning just 2nd ago is that we expect our margins to continue to steadily improve So obviously, a lot of moving pieces right now, as you said. We're very focused on that, and We don't think that it will have any lasting negative impact on our bottom line performance.
All right. And then in the AMH segment, the margin there looks like it's a record In terms of that 24%, 25% number, I know that when you did your Investor Today, last fall, you had actually reduced the longer term margin target, I believe, to a 20% to 22% Number. So how should we think about the sustainability or maybe long term margin potential of that A and H segment?
I think the points you make are all sort of right on. And as you point out, I mean, we're Operating at the 24% range in Q2, which is a very good margin, which reflects strong execution, And strong operating leverage. Do I think longer term, I mean, would I commit to that 24 longer term? I mean, we're down at a point now We're prepared to change our longer term targets that we've laid out. But at these revenue levels, the business Should be able to sustain margins above the targets that we talked about back in November.
Mike, I mean, if you look at really all the many of the metrics in our business, I mean, the industry environment has proven to be much stronger than we laid out in So in many cases, we're sort of out ahead of where we would have thought we would be at this point.
All right. And then Greg, maybe a question for you. The unallocated expense number Looked relatively high, north of $13,000,000 I think it's the first time it's been a double digit Number in some time, what drove that? And can you give some guidance on what we should be modeling for unallocated expense in the second half?
So what drove it in the most recent quarter was the $3,000,000 contribution Bertrand referred to, what's Christian Bertrand referred to what's driven it overall would be higher trends in Compensation costs related to the higher performance that we've had as a business. Honestly, I don't when we Model and put our plans together, I don't really focus on that unallocated number. So I don't But I would say generally it's an SG and A number and our goal is to hold SG and A growth well below sales growth on a percentage basis.
Ladies and gentlemen, there are no more questions. So this concludes today's call. Thank you for your participation and you may now disconnect.
