Now, I would like to introduce John Kibarian, PDF's President and Chief Executive Officer; and Adnan Raza, PDF's Chief Financial Officer. Mr. Kibarian, please go ahead.

Thank you for joining us on today's call. If you've not already seen our earnings press release and management report for the third quarter, please go to the Investors section of our website, where each has been posted. Bookings in the third quarter were strong as we continue to realize the benefits from our investments in product development and customer support. As we announced in the September press release, we signed an extension contract with a large customer that involves bringing our characterization vehicle infrastructure, Exensio characterization software and eProbe machines to their manufacturing sites as well as expand usage at their R&D site. The eProbe machines under this contract are provided under a subscription. Expanding beyond the machines they have in their R&D facility, we now have shipped 2 additional machines that are in the process of being installed at their first production site. Also in the quarter, we announced that we licensed Tiber AI Studio from Intel. With this license for source code, we are integrating the Tiber AI Studio's award-winning data science operations platform directly into Exensio. Tiber AI Studio enables engineers to build and manage hundreds of thousands of AI models. Coupled with Exensio's existing ModelOps, which enables model deployment in the fab and test floors, this integration is designed to enable engineers to use Exensio to both train models as well as deploy them. On a stand-alone basis, Tiber AI Studio already had hundreds of users. As we talk with our customer base, we are hearing the same message. They have great proof of concepts using AI, but scaling and maintaining large deployments remains elusive. We believe the integration of Tiber AI Studio with Exensio, which we call Exensio Studio AI is an important capability required to close this gap. Among the Exensio contracts signed…

Thank you, John. Good afternoon, everyone. Good to speak with you all again today. We are pleased to review the financial results of the third quarter and to bring you up to date on the progress of the business. We posted our earnings release and management report on the Investor Relations section of our website. Our Form 10-Q 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 a reconciliation to GAAP financials is provided in the materials on our website. As you saw from our press release, with our Q3 results, we achieved another record for quarterly revenue. Our bookings for this quarter totaled over $100 million, as a result of multiple large deals signed across our product portfolio of leading-edge Exensio and secureWISE. During the third quarter, our bookings were greater than the prior 2 quarters combined. On a year-to-date basis, for the 3-quarter period, our bookings were 49% higher than the comparable period of last year. With the contracts John mentioned as well as additional business closed in the quarter, we ended Q3 with backlog of $292 million, which is 25% higher than last quarter and 22% higher than the same period a year ago. We are pleased that we were able to grow our backlog while delivering record quarterly revenue. Our total revenue for the Q3 period came in at $57.1 million or 10% higher than last quarter and 23% higher on a year-over-year basis. Our Analytics revenue came in at $54.7 million or 12% higher versus the prior quarter, and 22% higher on a year-over-year basis. The growth in Analytics compared to the prior quarter was driven by business from leading-edge customers and equipment software. Integrated Yield…

[Operator Instructions] Our first question comes from the line of Blair Abernethy from Rosenblatt.

Nice quarter. I just -- I wanted to just ask you a little bit about the BFI. I see that [indiscernible] more machines. The machines that are under the lease model, when does that start to generate revenue? Is that some point next year? Or is that first half of this year?

Yes. We are going through the deployment and qualifications of those machines. Blair, as you know, those can take anywhere from 1 quarter or a little bit plus or minus on that time frame. So given that we have shipped, we expect within the next quarter or the quarter after, depending on the timing of those qualifications and the customer acceptances to start converting and generating the revenue.

Okay. Great. And how does the pipeline of opportunities look for the DFI right now?

Quite strong, actually. This is John, Blair. We do have other places where we would like to be able to ship machines. That's why if you did notice, we did spend some on CapEx this quarter in part to continue building machines, which we expect shipping in the first quarter of this coming year. We are hoping to squeeze in one more shipment this year, but it may be tight, just given the timing and what we're doing to bring up the machines already. So quite strong across a handful of customers. It's not a huge market for eProbes, but there's probably between 5 and 10 customers in the world, and we do have probably closer to 5 where we are actively engaged in discussion.

Okay. Great. And then just on the secureWISE, you won a large contract there this quarter. How is that -- how is the go-to-market there now that you've had it for a couple of quarters? Just kind of a sense of how that is building.

Sure. Yes. We actually had -- at SEMICON, right after SEMICON last in Phoenix this year, we had a little, what we called Connected Summit because in the past, the secureWISE team had had our users conference in conjunction. What was different about that was we had not just equipment companies come, but also fab companies attend. And in that conference, Intel presented how they are using secureWISE as their standard connectivity platform for both internally as well as to support the equipment vendors. We had felt that the way secureWISE had been run, it really only focused on the needs of the equipment vendors. And when we -- because of our DEX network, because of our work with the fabs and our -- just our general footprint, which, as I said in my prepared remarks, goes from everything from wafer makers through to system companies, we thought connectivity to the fabs was actually desired by lots of folks. In fact, when we announced that acquisition, the first congrats I got was from one of our largest fabless customers, who was very intrigued with the ability to get remote access at the OSATs and fabs. And so the Intel contract was a way of us, saying, okay, we're going to provide base capability on every machine at Intel. They announced that they're going to put this on every machine front end, back end and test facilities for their use as well as to make it available for some modest level of usage at every equipment vendor. When we talk to the equipment vendors that use secureWISE, one of their elements was not secureWISE itself, but the fact that they were not able to get it on every factory in the world, even if it was actually already installed at some…

[Operator Instructions] Our next question comes from the line of Clark Wright from D.A. Davidson.

Quick question just around the customer concentration mix. Your Customer A that you guys referenced year-over-year went from 19% to 38%. I'd love to understand kind of how you're winning bigger and as well as how you're looking at using secureWISE as a potential point of the spear to expand the overall customer base?

Yes, that's a great question. If you look at our business, really, we kind of think about it in 3 categories. There is the fabs. They tend to buy almost everything from us. If you look at just the discussion I had around secureWISE as well as the test vehicles, the eProbe, Exensio, et cetera. And those are very large contracts, typically multiple contracts with the same account. And hence, you see the customer concentration. It's really not often of one contract, but of many contracts that gets those customers. They represent typically between 40% and 50% of our business in any given quarter, just looking at how things work. The fabless and system companies are around 35% to 45% of our business, and that's about 100-something, 150-ish companies. We are seeing more interest in AI on Exensio, the Exensio Cloud, the secureWISE connectivity and some of the what we call orchestration products, Sapience products. There, we've had a number of wins over this past year and continue to drive business there. And then lastly, about 15%, and we think in the long term, closer to 20% are the equipment vendors. We have about 200 of them with the acquisition of secureWISE that certainly grows our business with those customers. And they have access -- they have desire for the same access points that the fabless did. So the way we think about it over the long-term clock, you can think about fab customers as a nexus point. And they run factories and they control the data, but they need collaboration with their customers to get qualified, and their equipment suppliers to be able to reach effective use of the machines that they purchase and put into use in their factories. And so secureWISE, as you pointed out, is the point of that spear because it allows us the collaboration across a number of those customers. And the Exensio contract that we did this quarter, it has an element with regard to secureWISE because they want to be able to reach their customers through secureWISE on the Exensio platform from a collaboration standpoint. So this is how we see PDF becoming a platform for the industry rather than a platform for each individual company. And secureWISE is a very important element to that.

Awesome. Appreciate that color. And then just as it relates to the announcement made in the end of September around the landmark contract, you reaffirmed your guide for this year. Is there anything we should be considering as it relates to kind of the 2026 picture and what you can say so far around how that deal potentially sets up the company for kind of the next leg of growth?

Yes. We haven't given guidance for 2026 yet, and we'll do that as we get through Q4 and we do our Q4 call. But obviously, as we grow backlog, you asked a question about other, we do see a number of other opportunities on the horizon for the company over the next couple of quarters. We hope to have a strong 2026 on top of a very good bookings 2025.

Our next question comes from the line of Gus Richard from Northland Capital Markets.

I'm just curious on the systems you're sending to the production site. How many tools per fab do you think the customer is going to need?

Yes. I think it's early to say, Gus. Obviously, we've put two in the first site. Two is a good number because at least as these things are used in mission-critical manufacturing, if one were to go down, you would want to be able to at least route critical material to the other. So I think very rarely would it be one? I think the minimum number is two. And then the question is, with any inspection capability, how much of the dance card can you fill up? What we've noticed as we've installed machines around the world is it gets very quick to get these things filled at very high utilizations in part because they can see things that are very hard to see or maybe nearly impossible with other systems. So we'd like to go beyond the two, but right now, we think two.

Okay. So these are near production, but not necessarily in line, not -- there's not...

Not in product, that's in your words. No. I said the reason why they want to is if one goes down, they want to be able to continue production, right?

Okay. I just want to get it clear. And then of the -- you have several systems going out end of this year, beginning of next. I just want to understand, are these evaluation systems or are they for revenue?

These are mix. It will be a mix and then the next set of machines. There'll be a couple on eval and the remainder will be revenue machines.

[Operator Instructions] We have a follow-up question from Blair Abernethy from Rosblat.

John, I just wanted to follow up on the Hybrid AI studio. Can you just -- you said there's 100-or-so customers for that. I'm just wondering if you can give us some sense of the time line of when that can go to market with the Exensio platform, i.e., when is the integration sort of ready for customers?

Sure. And I said actually hundreds of users. It's actually a very, very small number of customers, Blair. And -- but thanks for asking that clarification. We will have an integration at the end of this quarter. We actually signed this contract quite a long time ago, but due to timing of other contracts, we needed to wait before we could announce it. And we had had discussions with them going all the way back to 2024 around this opportunity, we had evaluated it in early Q1. As you can imagine, we were pretty busy in early Q1 because we're also closing secureWISE and then signed contract towards the end of Q1, then executed some activities in Q2 and announced in Q3, but we do -- so as a result, we've been working out with this code base for -- since all of Q3 and into Q4, and we expect to release some first level of integration with Exensio at the end of this quarter for some early access customers.

Okay. Great. Great. And then just on the Exensio Analytics business, what is the -- what's the renewal book look like as we kind of head into the end of 2025 here versus last year? And are you -- and maybe in recent contract signings, what sort of any changes in the term length of Exensio contract?

Yes. Typically, term lengths are 3 years. There are some that go as long as 5 and some that are short as 1 or 2. Our book is quite robust. The large contract we signed, the 8-figure contract we signed this last quarter was probably one of, if not the largest, stand-alone Exensio MA contract in the history of the company, as other larger contracts tended to have test operations or other components included in there. What we are seeing, we're going to talk about this at our user conference. Customers really want to have a scalable AI-first analytics capability. We're going to show our road map and what we're doing to have kind of analytics with AI-first, and what that means in terms of parallelization, the advances we're making around how to get to very large data sets interactively. They want the human interactivity with data still, but they want to be able to operate on data where you've got 1 million parameters and 10 million data points. And you really can't do that with conventional business intelligence tools, right? If you look at Exensio or any of the tools out there, you're limited by the compute. And -- we're going to show what we're doing to break through that problem. Studio AI is a very -- is an element to that, a very critical element to that because even when you're interacting with 1 million parameters, you need to use AI methods to screen and to tell you what part of that data set you should look at. And so what we'll demonstrate in December is ways of being able to operate interactively, leverage AI first and move -- work with data sets that you really couldn't do anything, but a batch mode in the past by leveraging basically a native AI approach and a natively parallel approach. You can think of a lot like moving algorithms from CPUs to GPUs, you get to scale with compute. What we will show is how you can leverage GPUs and other computing elements in an interactive analytics capability. And we are hearing from our customers that this is what is desired. We have a number of renewals that are coming up this year, and primarily next year that I think will benefit from this capability.

Okay. Perfect. Great. Yes, excellent. The other question I just had was around Sapience. Anything to report there or any progress with the partnership with SAP?

Yes. We've got a number of activities going on, on Sapience contracts. We do expect to announce something related to Sapience in Q4 in terms of customer -- additional customer business. And you'll see us announce something in the Sapience family at our user conference that's really building on top of Sapience some capability targeted to the fabless and system company that we expect to announce at our user conference.

Our next question comes from the line of Clark Wright, D.A. Davidson.

Awesome. Appreciate the time. Look, any findings from SEMICON West in terms of how the end markets and the health of those sound relative to the beginning of the year or your expectations?

Yes. Clark, it's a great point. It was an interesting SEMICON, I think, because it's the first time SEMICON West was not in San Francisco, people couldn't go in and out. You're kind of stranded in Phoenix. So there was a lot more informal conversations. And we did meet with also a lot of our -- not just our equipment customers, but I would say our fabless customers and a lot of our fab customers. And what we heard were a few things. Yes, the build-out on AI is continuing to go on. All the equipment customers participating in advanced packaging, everything around advanced nodes, on logic side do see and on the DRAM side, do see a pretty rosy outlook for 2026. I do think they're in a pretty strong position. Our customers selling into automotive, industrials and communications, the ones with very differentiated products do seem to be talking about a robust 2026, I think that's still a mixed bag. There are customers in that sector that have some challenges to work through, but I would say for the first time, the kind of ones that have very differentiated products that are much more bullish. So I would say you start seeing kind of a more broad base of enthusiasm within the customer base, than, I would say, 3 months ago or 6 months ago, where it was really limited to just the people on the very advanced nodes and advanced packaging. So I do think it was more broad, not fully, I would say, not fully broad to everybody, but definitely more broad than where it was in terms of positiveness than where it was 3 or 6 months ago. And then lastly, I would say, our fabless customers as they are becoming more and more embracing advanced packaging are recognizing they're becoming a manufacturer. And that means ability to communicate with the OSAT, more complex test data feed forward and other test flows. We had a lot of dialogues with customers on that topic and how can they effectively become more aware of what's going on in manufacturing. In the past, they would order a wafer from the foundry. And once they hit wafer sort, there wasn't a lot to worry about. But now they've got everything from operationally make sure they have organic substrates available and manage the supply chain of that -- of the production post the wafer sort as well as having many more test insertion points and needing to be efficient in how they leverage. And we've heard a lot of dialogue from customers in that regard. And I think that will be a growing area, as we move from just the very few high-valued, not terribly high-volume chips driving advanced packaging today to a much broader set of customers trying to leverage these advanced packaging test flows.

Got it. And then in terms of Cimetrix and kind of the shadow backlog, last quarter, you kind of referenced the fact that tens of millions there, has that upticked as well this sequentially?

Yes. As I said in my prepared remarks, we had a very strong quarter. We referred to it as revenue because the booking and the revenue happened in the same quarter on the runtime licenses with secureWise. In other words, we get designed in on the SDK and then they ship. What we noticed is, as I said in my prepared remarks, at the end of 2024, and we see it again this year, is more equipment is shipping with our software than with any of the proprietary software systems that the companies build. And I think that's really giving our software the reputation of being very robust and very applicable. A lot of our equipment companies that used to be on the front end are now trying to bring in tools to the back end. Our software is already proven in back-end assembly facilities. Our tester companies are doing much more sophisticated system-level tests with more robots, and our software is very proven with that capability, too. So we do see a fair amount of activity, design activity in some of the customers evaluating our SDK. Net, when you look at our runtime licenses, Q3 was very significant. It was a good quarter for us, a very good quarter for us. We don't get a lot of visibility. So we hope to sustain that in Q4. We don't have as much visibility because we only see it when they ship. But overall, while quarter-by-quarter may be difficult to predict on an annual basis, the trend is quite positive as more and more equipment ships with our software, and they use our software for more functionality, which means they buy more of the Cimetrix modules.

Our next question comes from the line of Andrew Wiener, Samjo Capital.

I wanted to maybe follow up on, I think you touched on it a little bit in the last answer, but I noticed that 2 of your partners in the test space, Advantest and Teradyne both posted very strong results and outlooks. And you've talked in the past about Advantest and the complexity around test being a strong secular driver for the company. Can you maybe elaborate a little bit on what you're seeing and how the opportunity for us? Is it coincident with -- as they see strong shippings, does our bookings or opportunities lag theirs and sort of any other color you could provide?

Sure, Andrew. Thank you for the question. Yes, you're right, it tends to lag. We see that, by the way, with our yield ramp business over the years, too. And kind of my prepared remarks saying we've seen lots of people building out 3D production and test and assembly with -- and now they're trying to figure out how to get a good return on a lot of these investments. We see that with -- that's part of what's driven our characterization vehicle and eProbe bookings over this year and a lot of our evals that are ongoing are folks recognizing they've got to get a return on what they've just put on the ground. So we would expect on the advanced test for advanced packaging, we will also lag our partners in that regard. The biggest application we see, and we've got a number of pilots going on with customers is data feed forward. And what this means is they have -- as there's many more packaging steps, they have a lot of test insertion points. So they test more than once at wafer sort, more than once at final test and once at system-level test. There's multiple wafer sort tests, multiple test points package, even sometimes as part of the package flow. And then finally, system-level test. And they do these at different temperatures and different conditions for these very large data center chips. The nature of that is they want to see forward data. Typically, they take the raw data, run an AI model, extract features and send it downstream to another test insertion point. And as the data is coming off that test, they will use that as a basis to decide to test more or test less. Our original strategy on this, Andrew, was to…

Okay. And would you think that would be like a 2026 sort of time line?

Yes. I mean, the majority of that business impact will be in 2026, to be honest. This year, there may be some additional contracts won, but the revenue impact will be de minimis.

And then following just -- I want to clarify something. So the 2 tools -- 2 DFIs that were shipped and are in the process of qualification, it sounded like the way you described it, they could get qualified this quarter, or maybe not. Is it then fair to say that, Adnan, I think in the past, you've talked about multiple ways to get to guidance. You guys feel comfortable with the guidance, even if there -- these tool qualifications slip into Q1?

Yes, Andrew, exactly. I mean, any time we're looking at a quarter, particularly when we're speaking to comments such as the ones that we put in my prepared remarks about, sequential growth for Q4, and also both in John's and my remarks about the reaffirmation of the 21% to 22% guidance, you're absolutely right. We're thinking about this and then other ways to get there. So look, if the timing happens this quarter, great, but like John said, there's many other opportunities we're working on across the product platform portfolio that we have.

And then maybe...

this is a little bit our timing. The timing on qualification would be towards the end of the quarter in any case. So the in or out is not a tremendous amount.

Okay. So again, the qualification of those tools regardless would be more of a tailwind to 2026 versus the earlier question about, correct. And then maybe just a little more color on -- I mean, obviously, you talked about rough engaged with 5 customers or potential customers on DFI. How -- is there memory customers in that bucket? Or are we still primarily focused on logic? And to the extent it's logic, is it -- you have 2 sort of other customers that have accepted tools? Are they looking at what your lead customer has done and the conversations around sort of a similar broader deployment along those lines?

Yes. It's actually all of the above. So with our existing customers, we see interest in more machines as they see the value, including the value of putting these in manufacturing and using these to monitor lines. They -- with new customers that are in the same areas our earlier customers, maybe at different feature sizes, but logic manufacturers. We do -- we started getting ongoing pilots with customers where they're sending us wafers and showing them what you can do. And it is a very unique capability. So we're able to show usually within a wafer or a few what you could see that's hard to see elsewhere. And then lastly, as I've said throughout the year, we have interested in doing pilots on DRAM for just about 12 months now, maybe 13 months. And you got by sending wafers to our facility here in California. And we're getting ready to be able to ship. I think the limiter on shipping is really us not at least one of those customers being in a position to ship given what we've been doing to bring up these machines and manufacturing this year. And at the engineering level, there's a lot of similarities to what we're doing in the logic side, but it's very, very different process technology, if it's memory versus a logic technology. But also exploiting the unique capability of the machine and the software.

Okay. And then just lastly on the Tiber. So just to be clear, like -- so it didn't -- we didn't come over with existing revenue. But in the press release, it said something about like supporting customers through this transition. Anything you -- sort of that contributes will be going out and selling once the integration is complete?

Yes, that's correct. The majority of the customers were not in semiconductors. Some have interest for us to support. And we may -- we are talking to only a very small handful about having them be supported on the stand-alone version of the product. Obviously, we licensed this from Intel. Intel itself was an internal user of the product. And for them, we will support it -- offer to support it both ways, both stand-alone and with Exensio. There's a lot, a lot of value getting it integrated in Exensio for a semiconductor customer, because it didn't really support any visualization of the data, the model, the results, just really visualization on running the models and algorithms. So Exensio and you didn't have a database for storing the data set you want to use. And then once you're done, you want to be able to store all of that information, so you could always go back and recreate it, and Exensio has capability for that model registration and things like that. So I think for that -- the user base, which is primarily at Intel, that was in semiconductors and using it, I think it's quite advantageous for them to use the integrated version. For the small number of non-semiconductor customers, they may use a stand-alone version.

[Operator Instructions] There are no further questions. Ladies and gentlemen, this concludes the program. Thank you for joining us on today's call.
