spk03: Thank you for joining us on today's call. If you've not already seen our earnings press release and management report for the first quarter, please go to the investor selection of our website where each has been posted. Today, I will start with a summary of our goals for the year, what we achieved in Q1, and finish with our perspective on Q2 and the remainder of the year. After my remarks, I will turn the call over to Adnan. As most of you know, our goal is to become the leading analytics company for the global semiconductor and electronics supply chain. we are focused on delivering business impact via improved process efficiency and product reliability. Among the requirements to achieve this goal are providing the right data, data quality, and analytics at the equipment edge. This is of growing importance not only to leading edge manufacturing, but also for manufacturers of more mature technologies across the supply chain. Our acquisition of Symmetrix connectivity products And our equipment company partnerships, including Adventest, directly address these requirements. The tool intelligence that connectivity and equipment company partnerships provide, coupled with Accenture's capabilities to ingest and drive actions from the data, is the growth driver of our analytics business. Increasingly, our customers want to utilize Accenture Analytics on the cloud to have immediate access to their data, and connectivity with their factory equipment, processing their products to optimize their production. Turning to the leading edge, our characterization solutions, including electrical test and our design for inspection, provide these customers with the deep data and insights required to develop and control advanced processes. Worldwide, investments in leading edge semiconductor manufacturing continues to increase and has become the focus of semiconductor consumers and governments as well as foundry and phallus companies. As a result, we anticipate bookings and contributions to analytics revenue from CV and DFI systems in Q2 and the second half of the year to grow compared with Q1 in the first half of the year. We will probably deliver these products as part of an analytics solution, but do have some legacy customers who are still buying our characterization capability as part of an integrated yield ramp with gain share royalties tied to yield achievement. With the expected growth in our analytics revenue, the integrated yield ramp revenue as a percentage of total revenues will continue to decrease over time. As we stated in our February call, we are in a period of higher growth for analytics revenue and associated investments as we head towards achieving our long-term model. Our expectation for this year was for our analytics revenue to grow by greater than our annual target of 20%. and we anticipated our total company revenues to approach 20% annual growth. In the first quarter of 2021, we started to see the results we anticipated in February, as our analytics revenue grew by more than 40% compared with Q1 2020. Growth in Q1 for total revenue was 14%, materially above the single-digit year-over-year growth over the past few years, and particularly strong when factoring in the decline in integrated yield ramp revenue. Looking deeper into first quarter results, our largest contracts were for Accenture Process Control, Accenture Cloud, and on-premise TBLs for Accenture Fabless. Additional strength came from increased runtime license sales of our Symmetrix connectivity software, which is installed on capital equipment. The strong and growing capital equipment volume suggests that this robust contribution to analytics revenue should continue through the year and is reflected within our annual growth expectations. During the quarter, we also had many new design wins for our connectivity solutions, meaning our equipment partners are designing our connectivity software into their products under development, which in turn will result in additional runtime licenses in the future. We accelerated our investments in cloud infrastructure and field deployments, as well as our capability to support our customers on the leading edge. Overall, PDF has always been willing to invest in head of business when there's a future opportunity. At the same time, we expect to generate cash from operations this year, as we typically do. As we look towards the second quarter, we anticipate continued total revenue growth on a quarter-over-quarter sequential basis, similar to what we achieved in Q1. We believe this will come not just from strengths in Accentio Analytics and Symmetrix connectivity that we experienced in the first quarter, but also from our characterization systems and IYR solutions on the leading edge as we benefit from the investments we made in the first quarter. In summary, I am really excited about the momentum achieved this quarter. With Symmetrix as part of the team, I am seeing more ways the combination of analytics and connectivity differentiates us further in the marketplace. Moreover, customers' adoption of Accenture in the cloud is opening up new opportunities as they experience the benefits of an integrated end-to-end platform. Our recent increasing and deeper relationships with customer technical evaluations for DFI and CV systems are strengthening my conviction for the potential of our leading-edge business also. Now I'll turn the call over to Adnan, who will review the financials and provide his perspective on our business. Adnan?
spk10: Thank you, John. Good afternoon, everyone. Good to speak with you again today, and I hope all of you and your families are keeping safe. We're pleased to review the financial results of the first quarter and to bring you up to date on the progress of the business. We posted our earnings release in a management report in the investor relations section of our website. Our form 10Q has also been filed with the SEC today. Please note that all of the financial results we discuss in today's call will be on a non-GAAP basis, and the reconciliation to GAAP financials is provided in the materials on our website. We are off to a good start in 2021. Growth in bookings for the quarter continued the directional trend of 2020, where we booked more than two and a half times the level of bookings of full year 2019. For Q1, our total bookings, leaving aside symmetric, were double our prior quarter bookings, with a core business trend and transition to analytics continuing to deliver. We continue to win large customer bookings with multiple Accentio deals greater than a million dollars this quarter. contributing to our recurring revenues. In Q1 alone, we have already booked approximately half the number of $1 million-plus Extensio contracts compared to the total number of similar-sized contracts booked in all of 2020. As customers appreciate Extensio Analytics on the cloud, we have experienced growth in the contract sizes as well. Our largest contract in the quarter was with an existing customer that increased their annual subscription license fee by more than 30%. The strong bookings in 2020 and the first quarter of 2021 lead us to believe that the pandemic and the subsequent semiconductor shortage has acted as a catalyst in getting semiconductor manufacturers around the world to manage their operations more efficiently and effectively with our analytic solutions. Total revenue for the quarter was 24.2 million, up 14% versus Q1 2020, and up 8% versus the fourth quarter of 2020. We were particularly pleased with a 26% revenue increase in the Asia-Pacific region and a 22% increase in Europe on a year-over-year basis. Analytics revenue was up 46% to 19.4 million versus Q1 of last year and up 34% sequentially from Q4 of 2020. Contributions from acquisition of Symmetrix played a part in the growth of analytics revenue this quarter. Even putting some metrics aside, the core Accentio business grew double digits percentage versus Q4 of 2020 and versus Q1 of 2020 was well ahead of our 20% annual growth targets. Within Accentio, we are seeing an increase in adoption of our cloud offerings as greater recognition of the convenience and the effectiveness of our analytics platform is realized. We also welcome new customers from Symmetrix in our list of top 20 analytics customers this quarter, which we're very pleased about. Our Accenture cloud revenue in Q1 was more than double our Accenture cloud revenue of comparable quarter last year. Combined with the radical revenue we derive from term-based licenses, SaaS cloud deals, and recurring revenue streams from Symmetrix, we are building a strong ARR-based software analytics platform. This gives us predictability, which coupled with growth of bookings in analytics platforms allows us to feel comfortable about a large percentage of our next quarter's planned Accentio and Symmetrix revenues. Within analytics, the DFI and characterization products combined revenue was down on a sequential and annual basis for the quarter. The confluence of geopolitical developments, automotive supply chain shortages, and increased U.S. focus on semiconductor production means that with our analytics, DFI and characterization capabilities were uniquely positioned to help achieve the industry vision. Therefore, this year, we expect to capture more value from our investments. For the first quarter of this year, analytics comprised 80% of our total revenue. This mix of analytics and IYR may change with the continued growth of the analytics business and potential future IYR wins. We are gaining traction as we continue our transition to becoming the largest independent provider of analytics software solutions to the global semiconductor supply chain. Our IYR business contributed 4.8 million in Q1 2021 revenue. As most of you know, this is a business that we have strategically de-emphasized, but maintain it with a few selective customers while enjoying the royalty-based high margin gainshare revenues. As we have previously mentioned, we expect gainshare to decline in the second half of the year. On a full year basis, we remain confident about analytics revenue growth to exceed our 20% annual target and total revenues to approach 20% growth. Gross margin for the quarter was 61% versus 65% in last year's first quarter and in line with 61% of the prior quarter. Our expenses compared to last year were higher due to investments in cloud infrastructure to support our recurring revenue streams and from the acquisition of Symmetrix. These strategic investments will support future analytics growth. We remain committed to our 70% target gross margins with our growing Accentio subscription and Symmetrix product revenues. R&D expenses for the quarter were up $2.1 million versus Q1 of prior year and up $0.6 million compared to Q4, majority of which increased as a result of the Symmetrix acquisition, coupled with some smaller increases from personnel and subcontractors. SG&A expenses were up 1.3 million versus Q1 of prior year, and up 1.4 million compared to Q4, driven by Symmetrix acquisition. Taken together, our total expenses, including cost of sales, R&D, and SG&A, were in line with our plan, and we believe we will be able to manage costs to similar levels while delivering on the recurring and total revenue growth we are seeing. Net loss during the quarter was 1.9 million compared to a net loss of 0.1 million for Q1 of last year and net loss of 1.3 million for Q4. The increase in net loss was primarily attributable to investments related to a continued transformation to an analytics company and the Symmetrix acquisition. With regards to the balance sheet, cash, cash equivalents, and short-term investments totaled 132.3 million. compared to $145.3 million at December 2020. Cash flow was impacted by accelerated investments to support our business, due in part to cloud infrastructure investments, payments related to Symmetrix acquisition, and stock buyback of $4.5 million. We expect to generate cash from operations for the full year 2021, consistent with our history over each of the last 10 years. With a strong cash position and no debt, PDF is very well positioned to deliver on our organic growth and consider strategic acquisition opportunities as they become available. In summary, we are pleased with the overall direction of our business. We continue to make measurable progress in expanding our analytics business, benefit from the growth in recurring revenue streams and the Symmetrix acquisition. In the first quarter of 2021, analytics boasted double-digit revenue growth versus both year-over-year and the prior quarter. with strong bookings during the quarter positioning as well for the year. We are pleased with the results of the first quarter and look forward to a strong 2021. With that, let's open up the call for questions. Operator, please start the Q&A.
spk00: That is noted. The floor is open for questions. If you would like to ask a question, please press star 1 on your telephone keypad. Again, that's star 1 on your telephone keypad. We'll pause for just a moment to compile the Q&A roster. Your first question comes from the line of Kristen Schwab. Your line is open.
spk05: Great. Thanks for taking my questions. The commentary regarding large customer bookings, can we assume then that that might be taken as a reiteration of previous guidance that Advantest would get to a $10 million run rate before we exit the year?
spk03: Uh, actually, you know, these are bookings of new business, uh, Christian. So this is, uh, customers beyond Adventest adopting, uh, Extensio and our overall analytics platform.
spk05: Okay. Do we still expect Adventest to get to that type of ramp then by the end of the year, I guess then?
spk03: Yes, we do, uh, uh, Christian. And in fact, you know, we did say that there was, uh, you know, we announced in Q4, uh, include PDFs technology. We do believe that as we go through this year, we will get at least a little bit above that level as some of the new products that generate additional license revenue for us are starting to sell through. And we expect that to happen by the third quarter of this year.
spk05: Okay, Q3. All right, perfect. The industry seems to be going through a lot of different change, and we have a large you know, IDM out there who's decided that they're going to try to become a substantial foundry in the future. It reminds me of some of your other previous successes of other companies who made that type of transition in the past. Do you think there's, I'm sure you know who I'm talking about, do you think there's an opportunity for you guys Is there any way to handicap that? It would be helpful.
spk03: Sure. In my prepared remarks, I talked about worldwide interest on the leading edge. Certainly, when things get to be covered in 60 minutes, it kind of speaks to how front and center this is in the world. And I don't think it's just one company. We do see multiple companies around the world increasing interest their focus on the leading edge in the U.S. and China and Taiwan and Korea and other places. In my prepared remarks, I did talk about an increased amount of pre-sales activity on the leading edge in the first quarter, which in part resulted in some higher expenses. And we took on those expenses because we felt that we can't predict any one single customer or any timing of any single thing. But when this has happened in the past where the world starts focusing on leading edge, it's historically been pretty good for our leading-edge business.
spk05: Yeah, can you give us an example of, you know, I was trying to think of previously when the IBM Alliance happened and a certain set of customers kind of went from zero to, I think, a material number, but I can't remember. Can you remind us of that kind of ramp?
spk03: Yeah, so that is, sure. I mean, there were about three customers in that time period. If you go back, actually, I've done some remarks It was 2009, the last year we actually lost money for the year from operations. And then once those companies started to make that investment, it generated a couple hundred million dollars in cash from operations over the last decade or so. So when those investments happen, they tend to be very big. But we can't say when or if that's going to happen this time. But these bets, our customers are making very, very big bets PDS technology is very helpful in untangling the Gordian knot that is yield problems. And so, you know, I think that speaks to why we've seen an increased, you know, activity with customers around the world, right? I don't think it's anything specific to any single customer.
spk05: All right. Fantastic. Thank you.
spk00: Again, if you would like to ask a question, please press star 1 on your telephone keypad. We have our next question from the line of Gus Richard. Your line is open.
spk08: Yes, thanks for taking my questions. What percentage of your analytics business now is based in the cloud?
spk03: We haven't broken that out specifically, and I don't have the number in front of me. I know that for Accenture, it's becoming a sizable percentage of the total Accenture business, but I don't know off the top of my head, Gus. I looked at collectively with time-based licenses. I'll explain a little bit why it's like that, Gus. We have a lot of customers where they buy the cloud service through us, so they pay for Accenture, and we turn around and pay some of the money to our cloud supplier. We have other customers who already have contracts with their cloud supplier for the hardware portion of it, but they pay us for the cloud subscription of Accentio, including all the managed services. So then our gross margin in that case is higher, but the revenue is slightly lower. And we lump that in our time-based licenses, but effectively it's cloud because we manage the systems and we manage the data ingestion, et cetera. It's just who's paying the portion to the hardware provider.
spk08: what I'm trying to get at is, you know, how much of your software revenue is, um, ratable and how much of it is upfront?
spk03: Oh, um, yeah, the, the vast majority of it's ratable there. You know, I think last quarter there were, you know, as I've not said a number of customers that did bookings over $1 million. All of those were either time-based licenses or, uh, or cloud contracts. There was no perpetual licenses in the large ones. We do still have some smaller customers that buy some of Accentio on a perpetual basis, but it's a relatively minority of that business.
spk08: So most of the revenue, when you get a million-dollar contract, you generally spread over two or three years.
spk03: Correct. Typically, I think last quarter, almost everything was a three-year term.
spk08: Perfect. And then, you know, thinking about the electrical characterization business, and it's very different than the software business, although I know they're tied together, how does electrical characterization, you know, be it, I don't want to say pro, but you know what I mean, and DFI, how does How does that fit into your business, and how do you plan on monetizing that moving forward?
spk03: Sure. Yeah. So in my prepared remarks, Gus, I did talk a little bit about, you know, one historic – a small number of historical customers that we still do sell at an iWire basis. We've done that with them over many years now. But for the most part, I'll give you an example. Customer as a cloud deployment for Accentio – for process control in their factory. They are, at this point, more and more selling wafers where they are not doing the product test. It's a partnership with a customer that's kind of treating them like a foundry, even though they're historically not a foundry. And they use our Scribeline test structures and systems as a way of establishing acceptance on the cloud. So it is the analytics application system on the cloud that does a series of alignments and correlations of that scribe data, which is a very rich set of information, with all the upstream data. And they use that on basically like an MRB-like application to decide whether to ship the wafer to the customer or not. It's a combination of the scribe line vehicles and the cloud offering that they use. And they use the cloud for a number of other things as well.
spk08: And, you know, how do you – How do you charge that? What's the business model?
spk03: It's a subscription.
spk08: OK. So you'll do the characterization vehicles for the customer. You'll supply the parametric tester, and they'll pay a fee for usage.
spk03: On an annual basis, correct.
spk08: On an annual basis, got it. And then the last one for me, and I'll let somebody ask some more questions. You know, what's the status of DFI in terms of placing additional systems in the field and with your key customer?
spk03: Yeah. So, you know, as I said in my prepared remarks, you know, we have an increased level of intensity on the activity on DFI in the first quarter of this year. And we expect to place additional systems as we get into the remainder of this year. I think timing may be end of second quarter, early third quarter, but we do expect that to happen.
spk08: Okay, just with multiple customers?
spk03: We've got activity going on with multiple customers at this point. Again, part of my prepared remarks, I think there's DFI activity going on with three or four customers at this point.
spk08: Is it reasonable to assume they're all leading-edge logic?
spk03: Yeah, it's reasonable to assume that.
spk08: Yeah, okay, okay, I got it. All right, thanks so much.
spk00: Your next question comes from the line of Andrew Wiener. Your line is open. Please go ahead.
spk07: Hi, good afternoon, John. Hey, Andrew. Following up a little bit on Kristen and then Gus's question, When we think about potential activity in DFI and CV, for that matter, with leading-edge customers, is it built into your current guidance more expectations of significant bookings with a small revenue contribution? How should we think about that? Given, obviously, the ASPs you've historically talked about, particularly with DFI, I would think if we start to see, you know, significant success, you know, selling multiple units, that that would, you know, add a tailwind that you didn't see, you know, when you were exiting, when you were on the last call and gave sort of a similar guidance.
spk03: Yeah. So, you know, Christian asked this question as well, kind of a little bit different way. And, you know, with kind of looking back in the past, It takes years to build that up, but the chunks are relatively large. As we look out over the next few quarters, we do expect characterization. It may be a mix of a little bit of yield ramp capability and some CV and DFI capability picking up over the next few quarters. We expect it to be more modest in the next couple of quarters and build up from a revenue standpoint and build up more substantially while the bookings can be relatively meaningful.
spk07: uh in this year the bookings will be more meaningful you know if we're successful the bookings will be more meaningful than the revenue impact the revenue pack will be relatively modest in this year okay and and just to be clear um when you say that some of the customers you're talking to at the leading edge or you know talk you're contemplating an iyr model so that would be you know a iyr services engagement with a royalty back end or would it be more a – it would just fall in the IYR category but be some sort of ratable revenue recognition?
spk03: Yeah. To make sure I'm clear, right, it's an existing customer that's used a gainshare contract in IYR in the past, and it is like the contracts we've done with them in the past, which is deploying, measuring yields, and establishing a gainshare period over many years.
spk07: Okay. Um, but the other leading edge players would likely fall within the analytics category. This is the way the lead DFI customer currently has.
spk03: Yeah, that's our expectation.
spk07: Okay. Um, and then secondarily, um, yeah, it was nice to hear that, you know, had a number of seven figure, um, 10 CO wins in the first quarter. Can you talk a little bit about what type of pilot or beta or pilot activity you have ongoing and what the pipeline looks like?
spk03: Sure. The activity level on Accenture continues to increase. This past quarter, there were a mix of Fabulous companies primarily using the cloud, some on-premise. Customers that use the Accenture process control that were doing relatively large renewals. In all the cases of the process control, there were only a couple of them, there were relatively big step-ups in their annual recurring run rate as there's new capability on process control that they wanted to include in their license. Adnan talked about that in his prepared remarks. As we look at the second quarter and beyond, we have a number of activities with customers A lot of continuation on the same theme. A lot of customers that have been historically with Accentio on-premise moving to Accentio on the cloud to get that extra productivity. We're releasing some new capabilities for Accentio Cloud that help customers manage their data, particularly for quality-sensitive markets like automotive and things like that that we're piloting with customers now. We anticipate seeing incremental upticks You know, I've been told that the way I describe this is confusing, but I call it expand the landed. When you look at PDF, we have a lot of, most semiconductor companies know PDF or buy something from PDF today. So we don't need to go and kind of knock on doors where folks don't think PDF means Acrobat. The customers that, you know, we sell to know that what PDF means and, you know, they already are using some part of Accentio and we're mostly doing a lot of expansion. So a lot of it is, There are some new names, but I would say the vast majority of it is expanding inside existing accounts.
spk07: Okay. And then I guess my last question is you sort of referenced with Symmetrix that there was, I guess you'd call them sort of new design wins where they're being designed into new systems that are being developed, I believe, was how you characterized it. I'm just wondering how significant those are, meaning how much does it expand either the customer base or the served market opportunity from a market share opportunity perspective?
spk03: Sure. Yeah. And thanks for picking up on that, Andrew. So yeah, the quarter to quarter, as we've kind of coming to learn about this business, you know, how much runtime license you get is the work the team did a year or two ago. getting the connectivity software designed into platforms. But they track very closely design wins, places where customers evaluate our connectivity solutions versus alternatives, do-it-themselves or other third-party systems. And the activity this quarter, the wins this quarter were up substantially over the kind of average run rate last year. And we'll see how that maintains for the remainder of the year, but we feel that bodes well for a run rate opportunities next year and the following year as those products, those hardware products, get put into the field. It's really hard to know how many more opportunities I'll do than the ones that they're taking advantage of, but the success rate is quite high. I think the connectivity product is very strong, and customers are very excited about connecting that with advanced analytics because there's a lot of folks like Adventest that have a tremendous amount of knowledge about their equipment. that they want to make available to their customers in the form of analytics. And connectivity is the first step in analytics, right? Got to get the data off the tool to be able to do something with it.
spk02: Thank you.
spk00: Your next question comes from the line of Tom Bisley. Your line is open.
spk06: Yeah, good afternoon. I was hoping, John, just if you could talk a little bit about – As you transition to an analytics software company, how has your ability been to attract and retain talent from an employee point of view?
spk03: You should always ask the talent. But, you know, we feel pretty good about the talent that we've been able to retain. We have locations in great places. Kim and I were in Salt Lake City last week. I finally got the vaccine, so I thought, good enough to travel, and I got to meet the team there. And we have a great team there, the Symmetrix team in 2020, one of the greatest places in Salt Lake City to work. And so, you know, that team is a strong team that's been able to grow, and we feel very good about the PDF teams. You know, in the other locations we added to the Bay Area this past year, and we added also in Vancouver we have an engineering team, and we feel quite good about those locations as well. We've tried to pick locations where people want to live. Obviously, Salt Lake kind of came with the acquisition, but it's a great place to live, and it's a great location for our team. So retention on the engineering side has been quite good, and the team acquisition, particularly in the cities where living is cost-effective, has been very strong.
spk06: Okay. And then I guess related... How much of your workforce at this point is kind of a work-from-home environment, and how much of it needs to be, I guess, centrally located around maybe a lab or a facility that you have?
spk03: Yeah, you know, I think the – I've always joked that the engineer's perfect work environment is, you know, their couch, a robe, and a bag of Cheetos. So, you know, for the engineers, particularly engineers doing software, which is the vast majority of them, They all tell me they feel the productivity working from home has been quite high. We've been doing surveys, and whenever I do employee meetings, we use the features in Zoom often to collect data from the team. And I think what the new workplace is going to look like, we're not going to go back to where we were before. Adnan and I are in the office today, and we do have people coming into our offices now In the U.S. as well, our Dallas office is back open. Salt Lake never really closed. And our offices in Asia, folks go in every day, particularly in Taiwan and in China. So, you know, it's coming back, but I would say that people are not going to be back in typically five days a week. It'll be working from home some number of days and working from work some number of days. We are trying to encourage people to stay near a city where we have an office so they can go in some amount of time. I really believe The dialoguing and whiteboard stuff, whether it's for business development or product vision and strategy, is always valuable. But our teams are geographically spread out anyway. So a lot of the folks you interact with are not in the office. If you're, let's say, in Santa Clara, a lot of the folks you interact with are not in the Santa Clara office anyway. They may be in the Salt Lake office or in Dallas or Vancouver or wherever. So our folks are going to be working in a distributed way on a going forward basis, probably more than we did in the past, but not 100% distributed.
spk06: Okay. Now, it's great to hear it because a lot of companies we talk to are having issues, you know, ramping up software development teams. It sounds like you've got a full complement in hand already.
spk03: Thank you. Thank you. Okay.
spk00: Your next question comes from the line of Gary Schneiro. Your line is open.
spk09: Hi, John. Hey, Gary. I wanted to go back to the conversation of the DFI placement. I assume that those are the E-probes?
spk03: That is correct, yep.
spk09: And can you tell us how many E-probes have been placed already?
spk03: There's a couple in factories, at least in two different factories.
spk09: Okay. And so when you were saying increased activity, additional systems, I assume that's more than one that you're going to place later this year?
spk03: Yes, we believe that.
spk09: Okay. That sounds great. And Gus had asked a question about, and it was answered that the vast majority of, is it your total analytics revenue is ratable, or... Just Accentio revenue is ratable. Can you clarify that?
spk10: Yeah, I mean, frankly, even within Accentio, if we were to look at our components that go into the ratable revenue that John mentioned, you know, the time-based license is, you know, professional licenses, some of the cloud licenses that we have, as well as the ratable portion that we get from the Symmetrix, because there's a portion there that's ratable. Yes, it's the software that shifts from the machine to the machine shipment. We get that revenue right away, but then there's some support and maintenance contracts that are ratable. So measuring as a percentage of our, and I know we don't break this out, but within our I was looking at SNC and CCG, but if you looked at within the analytics, it's probably about half already that's ratable. We do have to make some adjustments. This is why John was also cautious because within the way we currently classify TBL, it lumps in there a couple of things. It lumps in there the ratable as well as some of the upfront piece as well, which is why we need some more time to do that work to clean up. But it's starting to head towards being about half ratable as a percentage of the analytics.
spk09: Great. And it sounds like you're saying that you're working on getting a more specific number for us going forward?
spk10: Yeah, this is, I mean, it's a great question. Everybody asks that, and we need to do this. So as we've been transitioning the business, we expect that, you know, hopefully by the later this year that we can be talking to you about that number, if not sooner.
spk09: Okay, great. And I think, John, in your prepared comments, you said that you expect second quarter total revenue growth quarter over quarter to be similar to first quarter?
spk03: Yes, growth over fourth quarter. Correct.
spk09: Okay. And is it fair that third quarter over second quarter and fourth quarter over third quarter should be similar quarterly growth rates, or is there something that you see for the second half of the year that you would expect that to slow down?
spk03: Yeah, we've given a specific number on an annual basis, Gary, that we expected to approach our total revenue growth to approach our analytics growth target of 20%, but we haven't gone and broken it down specifically within third and fourth quarter. We have said we have the headwind of some gainsharing contracts tailing off in the second half of the year, but we feel very confident comfortable about the bookings growth that we are experiencing in this customer activity to grow through that headwind. We grew through a relatively significant headwind this quarter. As you know, if you looked at the IYR revenue, Q1 versus Q4, it was down pretty substantially, yet we still grew. So, you know, we're not breaking it out right now, Q3 and Q4, but overall we do expect the second half of the year to be stronger than the first half of the year.
spk09: Okay, great. Yeah, I guess... trying to connect the dots on understanding that the IYR is weak as happened. And the analytics is growing, but your analytics was up 46% year over year in the first quarter. And I assume that healthy growth rate should continue. But in your press release, I think you just say greater than 20% growth, which it doesn't seem like much of a bogey.
spk03: Well, we like to exceed our bogeys, Gary, and we feel pretty good about what we're going to be doing this year.
spk10: Yeah, I mean, there's a lot of shifts, like John mentioned, happening, right? There's the DFI business that you expect to win. There's the ramp and the very successful symmetric acquisition of what the team there is delivering, offset by the Gensher. So there's a lot of moving pieces this year, which is why we're comfortable saying what we have.
spk09: Right. No, I appreciate that. I guess just back to the DFI. that additional machines at existing customers?
spk03: Yeah, I think at this point what we're comfortable saying is we've got activity going on with a handful of customers and exactly handicapping where we install when I think is still not clear to me. We don't have a lot of bandwidth, right? So we will be at some point limited by what we can bring up when. And customers will have to see how important this is to them and who wants to make sure we have capacity for them.
spk09: Meaning you have multiple customers interested. You have more customers interested in more devices than you have at the moment. Is that what you're saying?
spk03: I think we're limited greatly by our capacity to install and bring up. We have some machine limitations as well. I think right now we're just still with the pandemic. I think Tom was asking the question, like, can people work from home? And for everyone on the Accentio and the Symmetric side, absolutely. For the DFI side, you know, not so much. And so that, you know, I'd like to kind of not be too specific there because we've got to go see what's going to come through first and how many of these things we could do.
spk09: Got it. Okay. Great. Thanks.
spk00: The last question that we have is from the line of Oren Hirchman. Your line is open.
spk02: Hi. Congratulations on the progress. Hi, Oren. Hi. In terms of narrower features, smaller line width, and more difficult yield situations, is that making a difference in terms of the acceleration on the bookings? What is driving that acceleration? Is it just, in general, the expansion of FAP capacity? If there's more color even, and you've given a lot of color, but if you can give even more.
spk03: Sure. I think in general, for the greater Accentio and Symmetrix connectivity, it's really just the increased activity in semiconductors, particularly with the Symmetrix products. They ship with every piece of equipment. And equipment volumes are up, and they're up on many mature nodes, too. It's not about the leading edge. With respect to design for inspection and electrical characterization, smaller feature sizes is one of the drivers. But I would say almost the most important one is the 3D nature and the 3D complexity of silicon processing these days. A lot of what you would normally inspect on the surface of the wafer isn't what really drives yield loss, right? Conventional inspection today is still primarily using a light source. So you look at the surface of the wafer. But at least half of the yield loss that we see on leading-edge parts is really about the connections in between the layers, whether they're shorted or opened. And, you know, electrical test structures as well as some of the things we're doing with DFI really allow you to look at those between-layer drivers, and that we feel is a bigger driver for our characterization solutions per se than the feature size itself. But I would say broadly the analytics business is just about the increased activity in semiconductors overall. It's really just the characterization of DFI that are very sensitive to the number of players investing on the leading edge.
spk02: Okay. This is a question I should know the answer to perhaps, but I don't. When you collect the billions of data points that you collect, obviously they're available to the customer himself. Of course. Are those data points anonymously able to be used by you to continue to perfect algorithms across all the customers?
spk03: Yeah, that's a great question. So in our cloud contracts, we usually request and the customers allow that we can use the data to improve our algorithms, improve our systems, because the customer benefits from the fact that our data systems can process data faster, our algorithms can detect outliers and defects more effectively, So it's good for the community overall if we can make our analytics better. And so we've put that in our contract, and, you know, we manage a few petabytes. We have – Accentio manages petabytes of data these days. We on our cloud solutions are managing a growing fraction of that. And so, you know, we use kind of our existing capabilities and sandboxes to optimize and improve things like our ability to load data in parallel fast, to retrieve data fast, and our customers will benefit from newer analytics, newer ways of slicing and dicing data.
spk06: Mm-hmm.
spk02: Okay, and finally, in terms of, you know, again, I don't know if there's an answer that you guys know that yourselves, in terms of how long it will take to go across, you know, so many instruments and different back end, et cetera, how many years before that really gets to the point of a critical mass where you kind of get a picture from beginning to end of the whole cycle of the chip? you know, right through final packaging and assembly. And maybe you could do it perhaps even today across an individual company if they so desired, but how does that vision unroll and how long does it take, et cetera?
spk03: Yeah, I think what you're getting, you're getting at a very important point, Oren. So, you know, our industry and our customers, generally speaking, you know, some of our fabulous customers are, A chip, they order away from a foundry, they send it to an OSAT to be tested, to another facility to be packaged, to another facility to be tested, and then eventually get shipped to a system manufacturer like Samina or Foxconn and put into a system. And never did that chip ever go through a facility that had that fabulous company's name on it. So visibility of data across their supply chain is very important. We provide a capability called the DexNotes, that give customers the ability to see their data at their OSATs and at least at some points as they come out of their foundries. The visibility inside the foundry process is relatively limited these days. So there is some level of that today for our customers. I think it could always be better than what is available today. Some of that's due to the limitations in the way the boundaries between companies. But for sure for tests and for some of the packaging and final test capabilities, Our customers use the DexNotes to get transparency there. And we are expanding that network of available suppliers as we go through this year. So more and more of their likely suppliers are already covered under the system.
spk02: And last part of my question is Symmetrix. How much does that accelerate this whole process for you?
spk03: That's a great point. Quite a bit. Symmetrix are a 30-year company with a long history of defining the standards for data collection. I think they chair something like 10 of the standards bodies at SEMI, but also in the Taiwan Printed Circuit Board Association and many of the other industry associations, whether it's in front-end factories, in assembly, in printed circuit board manufacturer, printed circuit board back-end. They are the leaders in working with the community in an open source way, an open way to define the standards in an open way. Obviously, our software supports those standards, but we want the world to adopt them, so we do that in an open fashion. We have quite a long history through that acquisition of working very closely with about 200 equipment vendors where we help them deploy those standards. That means, and that's why my last bit of prepared remarks, that we see a lot of ways we can bring closer together the analytics, With those data collection standards and new enhancements in the standards, so the latest things that have been proposed as standards but have not been fully accepted yet, we're implementing those in the software so our customers can get access to that because people always want the newest way to look at data and more insight about their equipment. So metrics is really quite an important piece to the overall vision of, you know, NTEN analytics standards. available on the cloud across the manufacturing supply chain. It's a very important part.
spk02: Will that be done on short order in terms of being able to give the customer access to that additional analytics?
spk03: One of the advantages of acquiring a company with a 30-year history is it can look like short order from the two of us coming together, but it's due to a tremendous amount of hard work that that team made over many years, decades in effect, to really define out these standards and get them adopted in the industry, get them into the equipment, and now connect them from the equipment to the cloud through a product they developed called Sapiens, coupled with, you know, the Accentio data collection engines. And so things we can do pretty quickly, you know, in a matter of quarters to see impact.
spk02: Okay, great. Thanks very much.
spk00: There are no further questions at this time. I would like to turn the call back to Mr. John Kebaryan, CEO of PDF Solutions. Please go ahead.
spk03: Thank you for participating in our Q1 call. We look forward to talking with you again soon. Have a great day.
spk00: This concludes today's conference call. Thank you all for joining. You may now disconnect.
