Good day, everyone, and welcome to Entegris First Quarter 2021 Earnings Release Call. Today's call is being recorded. At this time, I would like to turn the call over for opening remarks and introductions over to Bill Seymour, VP of Investor Relations. Please go ahead, sir.
Good morning, everyone. Earlier today, we announced the financial results for our Q1 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 our forward looking statements. Additional information regarding these risks and uncertainties is contained in our most recent annual report and subsequent quarterly reports that we 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 in 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. I hope everyone is staying healthy and safe in the present environment. Turning to our Q1 performance. Sales grew 24% year on year. Our growth was strong across all three divisions as we benefited from accelerating industry Conditions, several node transitions and strong overall demand for our products and solutions.
Gross margin improved sequentially as we expected and was up over 100 basis points from the 4th quarter. Adjusted EBITDA was up 25% year on year and non GAAP EPS was up 27% year over year. Let me provide a little bit more color on our Q1 revenue performance. From a product standpoint, we continued to benefit from accelerated demand for leading edge solutions, especially in liquid filtration, advanced deposition materials and Specialty Coatings. Sales to memory customers were up 40% year on year and up sequentially.
As you recall, Entegris content per wafer is rapidly increasing in the new higher layer count memory devices. In addition, our Aramus high purity bags, which are being used for the distribution and storage of the COVID-nineteen vaccine, recorded stronger sales than planned as our team successfully ramped new capacity. While sales growth was strong overall, we did face some challenges in what proved to be a very dynamic industry environment, particularly in the areas of freight capacity as well as supply chain and labor constraints in certain U. S. Locations.
We are aggressively managing these situations and we expect them to ease as we progress through the year. That said, demand for our products and solutions continues to be very strong and our order book is at record levels, which bodes very well for us as we look ahead to the Q2 and the balance of the year. More specifically, for the full year, our outlook for the industry and Entegris has improved significantly. The semi market looks very healthy, bolstered by a robust global GDP outlook and strong overall chip demand driven by accelerated digitalization, 5 gs and high performance computing. In addition, we have recently seen significant increases in our customers' CapEx plans for the year.
Given this backdrop, for the full year 2021, we now expect the market based on our unit CapEx mix Will be up 13% to 14% compared to our previous expectations of up 7% to 8%. And as I said, demand for our solution set continues to be very strong. And as a result, we expect to outperform the market and now expect our sales growth for the full year 2021 to range from 17% to 19% compared to our previous expectations of up 11% to 13%. 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 $3.15 compared to our previous expectation of non GAAP EPS greater than $2.85 Looking further ahead, we are very optimistic about the long term fundamentals of the semiconductor market. Accelerating chip demand and a higher proportion of wafers produced at the leading edge provide a great base for very attractive secular industry growth.
On top of this, at Entegris, we are benefiting from the growing importance for Process Materials and Materials Purity to New Device Architectures. We expect that these Key trends will continue to result in a rapidly expanding served market and increasing Entegris content per wafer. And all of this is supported by the strength of our team's execution and our highly resilient differentiated unit driven business model. Finally, I want to take a moment to thank our customers for the trust and confidence they place in Entegris and 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. Our sales in Q1 were $513,000,000 up 24% year over year and down slightly sequentially. Moving on to gross margin. GAAP and non GAAP gross margin were both 45.8%, slightly above our guidance of 45.5%. The biggest drivers of the increase were the expected improvement in SCEM's Gross margin following the weak Q4 and better overall factory performance.
We expect gross margin to be approximately 46.5 percent both on a GAAP and non GAAP basis in Q2. We also continue to expect gross margin will continue to improve throughout the rest of the year And be approximately 46.5 percent for all of 2021. GAAP operating expenses were 121,000,000 in Q1 and included $14,000,000 of non GAAP items from amortization of intangible assets, integration and other costs. Non GAAP operating expenses in Q1 were $107,000,000 which was slightly above our guidance range. We expect GAAP operating expenses to be approximately $122,000,000 to $124,000,000 in Q2.
We expect non GAAP operating expenses to be approximately $108,000,000 to 110,000,000 Q1 GAAP operating income was $114,000,000 Non GAAP operating income was 120 Adjusted EBITDA was approximately $150,000,000 or 29% of revenue and was also in line with our expectations. Moving to below the operating line. Looking at the other income expense line, a negative move during Q1 in the same currencies that favorably impacted us in Q4 resulted in other income expense going from $5,000,000 positive in Q4 to $4,000,000 negative in Q1. Our GAAP tax rate was 14% and our non GAAP tax rate was 15% for the quarter. For Q2, we expect our GAAP tax rate will be approximately 12% and our non GAAP tax rate will be approximately 16%.
For the full year 2021, we expect both our GAAP and non GAAP tax rate will be approximately 18%. Q1 GAAP diluted EPS was $0.62 per share. Non GAAP EPS of $0.70 per share Was up 27% year over year and down slightly sequentially. EPS would have been approximately $0.02 higher in Q1, excluding the negative currency impact on the other income expense line item I just mentioned. Turning to our performance by division.
Q1 sales of $167,000,000 for SCEM We're up 15% year over year and down slightly sequentially as expected. The year over year growth was primarily driven by advanced deposition materials, cleaning chemistries, specialty gases and advanced coatings. Adjusted operating margin for SCEM was 21% for the quarter, up over 300 basis points sequentially. The sequential increase in operating margin was primarily related to the improvement in the gross margin I just mentioned. Q1 sales of $207,000,000 for MC were up 30% from last year and up slightly sequentially.
Liquid filtration and gas purification drove the sales growth year on year. It's worth noting that gas filtration had its best quarter and years and is seeing the benefit of increasing WFE spending in the industry. Adjusted operating margin for MC was 34%, up significantly year over year and down slightly sequentially. Q1 sales of $149,000,000 for AMH were up 28% versus last year and down 2% sequentially. The year over year sales increase was driven by growth across all major product platforms, strong sales of our Aramis high purity bags and the impact of the GMTI acquisition.
The sequential sales decline can mostly be attributed to the catch up royalty income from Gudang Precision that occurred in Q4. Adjusted operating margin for AMH was 22 up almost 400 basis points year over year and down slightly sequentially. The year over year margin increase was driven by the Higher sales volume and solid cost management. 1st quarter cash flow from operations was $53,000,000 and free cash flow is $10,000,000 As a reminder, Q1 typically has the lowest cash flow of the year, primarily due to the variable compensation payment that is made during the Q1. CapEx for the quarter was 43,000,000 Given the strong demand environment, we now expect to spend approximately $225,000,000 in CapEx this year, up $25,000,000 from our previous expectation.
These investments are in support of our global product introductions, Capacity expansions, including the Aramis Bags and for the initial phase of the previously announced investment in our new Taiwan facility. Consistent with our capital allocation strategy, during Q1, we used approximately $11,000,000 for our quarterly dividend and we repurchased $15,000,000 of our shares. You probably saw that we recently took advantage of a favorable debt market and announced and priced $400,000,000 of senior unsecured notes due in 20.29 at an interest rate of 3.625 percent. We will use the proceeds as well as cash on hand and a small draw on our revolving credit facility to pay off the existing $550,000,000 4.625 percent notes due in 2026. This effectively extends the due date 3 years and lowers the rate by 100 basis points.
As a result of the refinancing, we are expecting $23,000,000 of one time costs, primarily related to the call premium for the existing notes that will impact GAAP EPS in Q2. And on an ongoing basis, with the changes to our debt, We are now expecting interest expense to be approximately $10,000,000 per quarter starting in Q3, a $2,000,000 reduction from recent levels. Now for our Q2 outlook. We expect sales to range from $530,000,000 to 545,000,000 We expect GAAP EPS to be $0.56 to $0.61 per share and non GAAP EPS to be $0.77 to $0.82 per share. In summary, demand for our products and solutions is the highest It's ever been, validating the importance of our offering and the strength of the market.
And we look forward to a strong Q2 and another record year. Operator, we'll now open up for questions.
Thank We will take our first question from Toshiya Hari of Goldman Sachs. Please go ahead.
Good morning. Thanks for taking my questions and congrats on the strong outlook. Bertrand, You revised up your market outlook for 2021 from up 7% to 8% to up 13% to 14%. Can you and sorry if I missed this, but can you differentiate between how you're thinking about the CapEx outlook for the industry versus wafer starts? And in terms of how you're thinking about your own business, the 17% to 19% growth for the year, if you can provide a little bit more color by segment, that would be helpful.
Thank you.
Sure. Happy to do that, Tasya. So we were pleased indeed to increase our guidance for the year. Those numbers are all organic, first of all. And back to your question in terms of what's behind the Industry assumption, while we expect MSI to grow in the low teens for the year.
And on the CapEx front, we expect CapEx and again here I'm talking about the industry CapEx not just WFE, but we expect CapEx to be up in the low 20s. And that gives you a blend of about 13% to 14% for the industry. And then again, an outperformance of about 4 to 5 points for Entegris, so very much in line with the commitments that we made during our recent Analyst Day.
And then how are you thinking about the segments, Bertrand? Is there any
Well, in terms of what is going to drive the outperformance, First, I think it's going to be a continuation of the trends that we saw in Q1. A lot of benefits that we expect to continue to see from the memory segment. 3 d NAND, as you know, is a big opportunity for Entegris, Nanofins, etch, selectivity and conformality becomes particularly important as more wafers are produced at 128 layers and more. And we expect about 30% of the wafers to be produced At 128 neos or more this year as compared to only 10% last year. So that's going to be a big driver for us And that will benefit our advanced deposition materials.
It will benefit our Specialty Coatings product lines and of course it will benefit our liquid micro contamination product lines as well.
Great. That's super helpful. And then as a quick follow-up, Bertrand, in your prepared remarks, you talked about some challenges related to freight And supply and labor, how meaningful were those headwinds in Q1? I'm assuming there was some revenue impact From those challenges and what are your expectations in terms of Q2 and the back half? You talked about some of these easing as you progress through the year, but should Should we expect some of these challenges to persist in Q2 and perhaps Q3?
Thank you.
Yes. As I said in my prepared remarks, So we are all very, very focused on managing the various constraints that we saw and experienced in Q1. And I cited 3 different types of constraints. 1 was the supply chain shortages that we Our own capacity limitations and then the last one was freight. So I think On the supply side, we expect those situations to ease out in Q2, Q3.
As it relates to our own capacity, we have a number of initiatives to add that will actually add capacity in In Q2 and then more additional capacity coming into the balance of the year. And then freight is a situation that Hopefully, it will get better as the general economies start to open up. But again, all of those various constraints and the plans to mitigate them are have been taken into account in our revised annual guidance.
Thank you. Congrats again.
Thank you. Our next question comes from Sidney Ho of Deutsche Bank. Please go ahead.
Great. Thanks for taking my question. My first question is on margin. You suggested gross margin will get still get to the 46.5% for the full year. But given the good start in Q1 and Q2, why won't that gross margin go higher?
And kind of related to that, if I kind of look at the operating margin side, Especially for SCEM, nice improvement there, 300 basis points quarter over quarter. Looking forward, can you help us understand what are the Key drivers to get to your target of 25% to 27%.
So, first of all, Sidney, on the gross margin, so through the first half, we had a 40 5.5% or a little over 45.5% quarter in Q1, I guess 45.8%. We expect 46.5% in Q2, so that brings us to an average of a little bit over 46%. To get to 46.5% for the full year, it implies back half margins Of about 47%. And so that those are our assumptions as it relates to gross margin. So we see some improvements Related to volume, we're counting we're not counting on better than average product mix, we're counting on typical product mix, but those are And then, the second part of your question, Could you repeat that?
I heard the 25%, but I didn't get the starting point.
Yes. Related to operating margins SEM, again, good improvement in Q1. How do we from the roughly 21% range, how do you get to that 25% to 27%, one of the key drivers to get there.
Yes. So it's really, three things. I mean, they've got We'll see continued gross margin improvement there in that business. We expect to They've made much of their investment in ER and D and SG and A, so We'd expect there to be pretty significant leverage on the improved gross margin. And then We've talked consistently about improving volumes in our specialty materialsgraphite business
Okay. That's helpful. Maybe my follow-up question is, Kind of relate to the earlier question that you answered. But beyond Q2, what kind of visibility do you have in the second half of the year at this point When compared to the same time in past years, especially given the semiconductor shortage or wafer shortage we're seeing? And maybe ask differently, if demand continues To improve, do you think you will be able to see much variability to your full year revenue forecast given supply shortages out there?
Thank you.
So Sydney, I would say that the visibility is actually pretty good right now. And our Order book is at record levels, as we mentioned earlier. So that gives us Good level of comfort for the rest of the year, and that's really what we reflected into the full year guidance. We talked about capacity and the constraints that we are working on resolving. We are all obviously very focused on that.
I mean short term, it's really about And I'm talking about Q2. It's really about getting the most out of the current equipment and infrastructure. So it's really mostly a staffing challenge here in the U. S. But we have been hiring and we are training a number of new shifts and we intend to operate at 724 in most sites, starting sometime in later in Q2.
And then in the back end of the year and second half of the year, New equipment is going to come online. That's going to provide additional relief, in particular, for our liquid filtration platform. And then if you go beyond that next year, obviously, we're going to start seeing the benefits of a number of new investments, including the new Taiwan site. And that's Important because our growth objectives obviously go well beyond 2021. We have very aggressive growth objectives for many years to come.
So we are very focused on the capacity short term, mid term and long term.
Great. Thank you very much.
Thank you. Our next question comes from Mike Harrison of Seaport Global Securities, please go ahead.
Hi, good morning. Good morning. In Microcontamination Control, you mentioned that Your gas filtration business had the best quarter in years. It sounds like that was more equipment driven. So can you, number 1, talk about what is driving the strength in the gas filtration business?
And then maybe talk about the sustainability as you think about equipment sales being maybe a leading indicator for some of the consumable sales Within that business.
So Mike, your assessment is correct. Our gas filtration business had a record And a lot of that comes from the increased levels of WFE spending. And we expect those levels of demand to continue at least for the balance of the year. And that's going to continue to benefit that product line again for many quarters to come. When it comes to the long term implications of all of that, actually, What we are most excited about in Entegris is not just so much the current level of New fab construction, but it's really in a few years from now, 2023 and beyond, when all of that new capacity is going to come online.
Those new fabs will be running processes, the most advanced processes in logic and in memory, Where we have higher content per wafers. So obviously, pleased with the short term increase in CapEx and what it means for some for product lines, but more excited about the long term prospects as those new fabs come online.
All right. And then within the Advanced Material Handling business, I believe you showed Revenue growth in the high 20s there, but you mentioned the strength in Aramis And the impact of the GTMI acquisition, can you give us a sense of what organic growth Would have looked like in that AMH business versus the 28% number that you showed?
Yes. So I mean, remember, given the timing of some of those acquisitions, I mean, the inorganic impact is relatively modest. And if you exclude the Life Science business, I would say that it would be in the high teens for AMH versus Q1 of last year. Is that the question, Mike?
Yes, that answers it. And maybe just one last one. You overshot the operating expense number by about $1,000,000 Anything any color you can provide on what drove that overrun?
Mike, not really anything in particular. I mean, I would say if I could point to one thing and I referred to it earlier that some of the investments In ER and D within our divisions, probably spend a little bit more than we initially anticipated. And that's not something, honestly, when we're spending more on ER and D, as long as it's within reason, I feel good about that.
All right. Thanks very much.
Thank you. Our next question comes from Chris Kapsch of Loop Capital Markets. Please go ahead.
Yes, good morning. Thank you. So you characterized your order backlogs At record levels, both in the formal remarks and in response to another question. I'm just wondering if you could characterize any instances Where your that demand growth those orders are outsized relative to your revised market expectations? And also is there any sense that some of this demand is above and beyond sort of the industry conditions?
In other words, are there instances customers are just desperately trying to build buffer stocks or is this just reflecting true end market demand?
So I think what we're seeing is really true end market demand. I think there is A high level of demand for advanced chips and for mainstream chips. And The demand for our products really comes from the high level of fab utilizations that we've been seeing across in most segments. Today, I would argue that many of our advanced fab customers, in particular, or running with very low levels of safety stocks, and in some cases uncomfortably low levels of safety stocks. So I think that again there is a solid pent up demand for our solutions that is based on actual demand drivers as well as a desire by some of our customers to get back to more normal levels of safety stocks for some of our products.
Fair enough. Thanks. And then just to follow-up on, I think it was your memory or sales into the memory fabs up I think 40%. And you also made some comment The architecture shift that's ongoing there in terms of expectations for the year. So just wondering if the current strength, is it reflective of just Across the board fab utilization rates in the memory end market or is it reflect the shift that's already happening?
Any color on the sort of the cadence of that and the direction, the trajectory of that business would be helpful. Thanks.
So So if you look at fab utilization, especially in 3 d NAND, there was really not a lot of change Q1 versus Q4. And so a lot of the benefit that we saw was coming from the migration to higher layer count devices that I was mentioning earlier. And you know that this is the type of architectures where we have higher content per wafer. And I would say that the rate of adoption of the new materials that we've developed for those architectures, the new chemistries that we have and developed. It's just accelerating as expected and as we presented during our recent Analyst Day.
So again, it's a trend that will be beneficial to us this year, but we expect more conversion to 128 layers in 2022, 2023. And if you go beyond 2021, we would expect More migration to 256 layers and beyond where we have yet increased opportunities for wafer.
Helpful. Thank you.
Thank you. Our next question comes from Patrick Ho of Stifel. Please go ahead.
Thank you very much and congrats on the nice outlook for the year. Bertrand, maybe first off on the advanced foundrylogic side, Traditionally, you've seen continued capital intensity increases in your microcontamination control business as we know. Can you just remind investors and myself included in terms of some of the materials opportunities that are Currently ongoing and whether you need to see the industry transition to the NanoWires
Yes. So we of course, we've been talking a lot about memory. And Patrick, you are reminding us that we have also great opportunities on the Thick front, and you're right. I think that we mentioned those opportunities and we quantified those opportunities in November last year and they are real. The opportunities will be for new metals, new High K Materials and Selective Etch Chemistries will start to also be Introduced with gate all around architectures.
So the next few years Will be equally exciting in Logic. And when it comes to no transitions in Logic, I think that the second half of this year, 2021. We will see some large customer transitioning to a new node. So that will actually drive Adoption of some of those new materials and those more advanced filtration solutions as well. So I would say that for us, the first half of the year is more of a memory story.
The second half of the year will be both memory and advanced logic.
Great. That's helpful. And maybe as my follow-up question for Greg, in terms of OpEx, it is going up slightly in the June quarter and you did mention bringing on additional labor. How much is that labor Content going to impact the rest of 2021 in terms of the OpEx line?
So when we see the increases in OpEx, primarily investments in ER and D and Some modest increases in SG and A. When we talk about labor, we're primarily talking about cost of sales And adding additional labor to help us meet the demands for our products.
Great. Thank you very much.
Thank you. Our next question comes from Amanda Scarnati of Citi. Please go ahead.
Hi, good morning. I just want to talk a little bit about SMIC licenses. Earlier in the quarter, There was news reports that Entegris was able to gain some licenses there. Can you just talk about the scope of what that looks like and if There's any ongoing discussions with the U. S.
Government in terms of expanding sales to China or any
So good morning, Amunde first. Let me start with the broader part of your question first. I mean, of course, the industry as a whole and Entegris in particular It's very engaged with the U. S. Administration right now, and it's important, especially in the early days of the new Biden administration.
And But I think generally speaking, I think that we need to accept that the semiconductor industry, because of its broad strategic importance, is Likely going to remain an area of tension between the two nations. So going back to the first part of your question, Like everybody else right now, we are very focused on complying with the existing rules. And for us, as we discussed in the previous Earnings call, it means applying for export licenses for all of our U. S. Made products and giving some time to the administration to review and Approve those licenses.
What I can share with you is that we have Some of our licenses received approval since the beginning of the year, but there are some that are still under review and we are awaiting But all of that has been factored into our Q2 guidance and our annual guidance. I mean, we've been modeling different scenarios.
Great. And do you think the fact that there's so many semiconductor shortages, The fact that SMIC is one of the larger foundries that that creates a little bit more of an easing of maybe material sales? Or is it just Sort of broad products that you've already been given licenses for?
Look, I Don't have that specific insight into how the administration is making decision Granting those licenses, I would just say that we are pleased to have received approval on many of our licenses. And I think that we are making good progress, and I am hopeful that we will get approval on the balance of From the licenses that are still pending approval, but okay, and we won't know until we hear from the administration.
Great. Thank you. Thank you. Our next question comes from David Silver of C. L.
King. Please go ahead.
Yes. Hi. Thank you. I was wondering We could just maybe talk a little bit about the Aramint product line. So there's a Couple of moving parts here, but back on Investor Day, I think you called out the Aramis product as something that was going to account for a full 1% of company growth in 2021.
And since then, a number of things have changed. You've raised Your growth targets, you've completed a capacity expansion, I believe you called that out. So I'm just wondering, If you could maybe update us on the expectations for the Aramis Growth this year. And then secondarily, is there was the current capacity expansion 1 of a Play in series or is that the final capacity expansion for some time now? Thank you.
Yes. So it is indeed a great story for us. And 2020 was really obviously a turning point for This particular technology, our strategy has always been to target emerging biologics. And the reason we wanted to target Gene and cellular therapies is that they have very unique supply chains and very unique requirements involving Free store processing, where those high purity aromas bags perform really, really well. As a matter of fact, We believe that our bags are just the best solutions in the market right now.
They have Lower extractables, lower leachables that makes them the cleanest bag available and they are More resistant than any other bag in the market. They can withstand gamma sterilization and they do not Break, they do not leak when they are frozen. So, with that as a backdrop, The projections for this platform in 2021 is now closer to $40,000,000 so a little bit more than when we last spoke, and that's the reason why we are adding capacity. We invested about $10,000,000 in capacity last year. We plan to invest about $30,000,000 this year.
By the way, those numbers are obviously included in the CapEx guidance that Greg And just to be clear, those investments go well beyond supporting the needs of the global COVID-nineteen Vaccination Campaigns. The strategy here is really to support the needs of by our customers as they develop the therapies of the future.
Okay. Thank you for that. I had maybe another question about supply chain in general and in particular, kind So at a number of points, you've talked about wafer fab utilization at extremely high rates, and you've cited Some of your customers running with uncomfortably low safety stocks. And your job, I guess, as a trusted supplier is So Whether it's in the enhanced CapEx budget or other areas, I mean, what are some of the tactical Steps that you're taking in the current business environment is to support your customers and I guess
Yes, it's a great question. I think I already attempted to answer it earlier. And as I said, we are very, very focused at all levels, at the Tigris right now to make sure that we have enough capacity Coming online in back end of this year and then ensure that we have enough capacity longer term To live up to the increasingly pace at which The demand for products is evolving and to meet customers' expectations. So again, a lot of focus short term on staffing And then mid term on unlocking the capacity potential of a number of investments in new equipment that we have already made And that will be coming online in back end of the year. And then longer term, it's all about expanding our footprint.
And the Taiwanese side is a good example of what we're trying to do. We're trying to not only just add capacity, but we're trying to Do that closer to our customers, so that we can reduce the cycles of learning during the development phase. And then of course then reduce our lead times when we start manufacturing locally. And then generally speaking, what we're trying to do is really just have Gradle capabilities on the ground close to our largest customer to better support them long term. Once The Taiwanese investment will be completed in 2023.
We would expect that about 50% of our production will be in Asia Pacific, which is where most of the semiconductors are being made today. That may change in the future. There are a lot of Discussions about that, but at least for now, it will rebalance our global capacity on a global basis.
Okay. And then one last one maybe for Greg. But Greg, I think you called out negative Foreign currency translation this quarter is a line item that may be nicked the bottom line by a couple of pennies. Can you maybe and I apologize if I missed this, but can you remind me what the key, I guess, currency relationship or relationships Negative effect there, I'm assuming a weak U. S.
Dollar, but not sure maybe versus Korea, Taiwan or whatever. And then maybe what's just if you could call out the key relationships, so maybe we could track that Over the next few months. Thank you.
Yes. So let me comment generally. So from P and L perspective down to the operating line, we continue to believe we have a relatively natural hedge Because we're selling in multiple currencies, but we're also both manufacturing and have OpEx in multiple currencies. So like I At the operating line, it's not a perfect hedge, but it's a pretty good hedge. Below the operating line, other income expense is What I commented on in the script really has to do with the revaluation of the balance sheet of our foreign subsidiaries.
So it has nothing to do with our revenue or our And the key currencies that are involved are the Korean won, Japanese yen and in the most recent quarter, the euro actually had some impact. And it's not it's too simple to say That is how they do versus the dollar, because it's not it relates to what is the functional currency of the subsidiary entity. And so it's something I mean, I can walk you through it in great detail, although I wouldn't want to do that on this call. But it really, like I said, it has to do with the revaluation of assets that are denominated in something other than the functional currency.
Okay. So a weaker dollar versus the yen and the yuan is what you were calling out. Is that Correct.
Weaker dollar versus the yen for sure Versus the Yuan, I'd have to go back and look at it. The Yuan but the movement in the Yuan, the Yuan moved in the opposite direction In Q4 that it moved in Q1, so we had a benefit in Q1 and a negative impact in Okay. We had a benefit in Q4 and a negative impact in Q1, excuse me.
Got it. Okay. Thank you very much.
Thank you. Our final question comes from parejus Misra of Berenberg. Please go ahead.
Thank you. Good morning and thanks for taking my question. In your SCM business, across the three Product categories, gases, cleaning chemicals and deposition materials, any contrast you could provide on Growth rates. Just trying to get a sense if all three categories had a similar growth rates or one is growing much faster than the others?
So first, I mean, you got it right, Bharatesh. I think those are the fastest growing business units within this division. Think about Deposition Materials growing in the low 30%, so very significant growth. And then Specialty material is a little bit of a tale of 2 cities because we have advanced coatings growing very, very fast. And then the graphite business that is still in a slow recovery mode.
But the combination of all of that gives you mid Roughly and then SBI is also performing at those levels and that includes our Selective Edge products, Which is a product that we introduced last year and is really going to be one of the big growth contributor for SCM going forward.
Thanks for that color, Bertrand. And then my follow-up, I was Wondering if you could comment on the M and A landscape in the microcontamination business. Are there opportunities So in microcontamination outside semiconductor that might be attractive to you?
Well, if you look at EyNow and the strategic rationale behind the EyNow acquisition, you're absolutely correct that we believe There are opportunities for us to venture in adjacent applications. And the best way for us to supplement The existing capabilities that we have internally is to find some of those tuck ins. So ANAL It's a very important piece to that puzzle. We're going to continue to look at other alternatives as well. When it comes to ANAL, I must also admit to the fact that the current pandemic and the travel limitations I've been a little bit of a headwind in terms of the cross pollinization that I was expecting to see between the U.
S. Development teams and to China based teams, but the business is very healthy and I hope that joint development work can start relatively quickly. But you're right, it's one of the few areas of focus when it comes to to M and A, the other area being materials as we have discussed in a number of occasions.
Thank you. That's all I had. Appreciate it, Gautam.
Sure.
Thank you. That concludes today's question and answer session. Ladies and gentlemen, this concludes today's conference call. Thank you for your participation. You may now disconnect.
