Following Greg and Sanjay's comments this morning, we'll open up the call for questions. This call is scheduled for one hour. Greg?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Thanks, Tracy. Good morning, everyone, and thanks for joining us. Today, I'll discuss our second quarter results and provide an update on what we're seeing across our businesses. Sanjay will then provide more detail on our second quarter results and third quarter guidance.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Through the second quarter, end market trends noted in prior quarters were generally consistent with strengthening second half. Strength in AI compute is more than offsetting lower demand in auto and industrial end markets. Pockets of improvement in mobile are driven more by customer specific dynamics than an uptick in the end market demand. Visibility is starting to improve. In terms of capacity utilization, we believe that we have turned the corner towards new more new system sales rather than selling upgrades of existing idle mobile capacity for new compute and mobile applications.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Demand is strengthening in AI compute, and we are seeing a broadening of opportunities where Teradyne and especially the UltraFLEX Plus is getting strong consideration in areas where we have not historically had a seat at the table. While new program ramps and new test insertions can drive a lumpy order pattern, we are optimistic about the opportunities on our horizon. In the second half of twenty twenty five, we expect AI compute to be the dominant driver of our SoC business. The long term themes we've discussed, AI, verticalization and electrification remain intact, with AI and verticalization emerging as the primary growth drivers in the near term. Our Q2 results reflect the evolving composition of our business.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

In the past, the typical seasonality in our revenue was heavily driven by consumer mobile demand. This has now been superseded by the waves of demand driven by specific customer program ramps in AI compute. These have no correlation to consumer holiday buying patterns. In the second quarter, we delivered revenue, gross margins and earnings per share above the midpoint of our guidance ranges. Semi Test, specifically SoC for AI compute, drove results above our expectations.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

End demand trends in mobile persist, but we saw pockets of customer specific strength in RF and mobile power in the quarter. In the industrial and automotive end markets, demand has stabilized at a low level. As expected in Q2, memory revenue was lower quarter on quarter due to the timing of shipments and is expected to snap back in the In second the quarter, our memory business unit secured an important HBM4 post stack singulated die win. HBM suppliers are adding test coverage to improve device quality. Some suppliers are adding a test insertion for HBM singulated stacks.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And while this new insertion is not yet pervasive across the broader industry, we believe that it is an important growth driver for the memory TAM in the future. This win builds on momentum from the HBM4 post stack wafer test win in Q1 for our memory business unit. As we discussed in our Analyst Day, there are four elements to growth in our IST business: accelerated bit growth in HDD, share growth and recovery in the mobile SLT market, emerging SLT for AI accelerators and solid state disk drives. In Q2, IST revenue more than doubled compared to the same period last year, mainly driven by HDD and mobile. All of the businesses within our product test group delivered second quarter results generally in line with our expectations and up year on year.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

In the quarter, we closed the acquisition of Quantify Photonics, accelerating an important element of our strategy to gain share in AI compute by establishing a leadership position in silicon photonics test. In robotics, recall that we executed a structural reorganization that consolidated the customer facing sales, marketing and service organizations of UR and MiR in the 2025. In Q2, this new organization delivered 9% quarter on quarter growth despite persistent difficult market conditions, and we continue to optimize our OpEx envelope to respond. In the second quarter, as part of our pivot to large customers, we secured a plan of record decision from a large customer. This is not expected to have a material impact on robotics revenue in 2025, but is expected to be a significant growth driver later in 2026.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

In support of this opportunity and others, the team plans to open a manufacturing operation in The United States to best serve customers in this region. Moving on to Q3. As we progress through the third quarter, we are gaining confidence in AI compute related revenue inflecting in the second half of the year, driven by both SoC and memory. We are less certain of the quarterly timing of shipments between Q3 and Q4 and then between Q4 and Q1 due to customer schedules. That said, we expect the relative size of AI compute in our SoC and memory business to represent the majority of our Semi Test revenue in the second half.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Our expectations for Mobile are modest in the third quarter and the second half generally, expecting that the bulk of the demand we'd see for the year has been satisfied in the first half. Growth in the mobile segment is coupled to the ramp of two nanometer gate all around and the expectation of more compelling AI applications in the generation of smartphones coming in the 2026. In the auto and industrial end markets, our end customers remain cautious about significant capacity adds, but we do not expect test equipment order patterns to deteriorate further. There are areas within this end market that are showing strength, like the power semiconductors for data center build outs, and we believe that the long term trend towards electrification will drive growth beyond 2025. Overall, we feel good about where we're headed in the third quarter and the second half of the year.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

We are significantly more confident than we were ninety days ago. Demand trends in AI compute have strengthened and forecasts are materializing into orders. Utilization rates have improved considerably, leading to an increase in UltraFLEX Plus system orders. With the work that we have done to increase the resilience of our supply chain and dual source our manufacturing, we are in a position to effectively scale volume with increased demand and provide timely delivery of our testers to fast moving customers. I want to emphasize that we are opening these new opportunities because of the scalability of our newest systems, our capabilities in silicon photonics, our parallelism and higher throughput that lowers the cost of test for our customers.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And with that, I'll turn the call over to Sanjay.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Thank you, Greg. Good morning, everyone. Today, I'll cover the financial summary of Q2 and provide our Q3 outlook. Now to Q2. Second quarter sales were $652,000,000 and non GAAP EPS was $0.57 both above the midpoint of our guidance ranges.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Non GAAP gross margins were 57.3%, consistent with our guidance range. Non GAAP operating expenses were $275,000,000 up year over year as we have increased our R and D investments and targeted opportunities to drive longer term growth. OpEx came in flattish sequentially as we continue to practice disciplined spending controls. Non GAAP operating profit was 15.1%. Turning to our revenue breakdown in Q2.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Semi Test revenue for the quarter was $492,000,000 with SoC revenue contributing $397,000,000 Memory, dollars 61,000,000 and IST, 34,000,000. Strength in SoC was driven by mobile upgrades. AI compute growth exceeded our plan. Expected memory revenue was considerably lower sequentially and year over year due to the timing of customer deliveries, which is expected to be back half weighted this year. In the first half of this year, customers have been digesting the HBM test equipment delivered in 2024.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

We expect DRAM to dominate the memory mix in 2025, just as it did in 2024. IST revenue of $34,000,000 was up both sequentially and year over year, driven by mobile SLT and HDD testers. In product test, Q2 revenue was $85,000,000 up 7% year over year, with all business units within product test up year over year. As Greg noted, we closed the acquisition of Quantify Photonics in the quarter as its results are included in this segment. Now to robotics.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Revenue was $75,000,000 up quarter over quarter, but down year over year. In the quarter, UR contributed $63,000,000 and MIR contributed $12,000,000 While the long term drivers of AI and onshoring and advanced robotics remain intact, near term macro factors continue to be a headwind. Our second quarter operating results were better than our first quarter, and we expect the second half of the year to be better than the first half. Despite this, due to the weak end market, we had lower volumes yielding a lower gross margin. We expect the weak market to persist and do not expect Robotics to break even this year.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Some other financial information in Q2. We had one customer that directly or indirectly drove more than 10% of our revenue in the second quarter. The tax rate, excluding discrete items for the quarter, was 13.5% on a GAAP and non GAAP basis. At a company level, our free cash flow was $132,000,000 primarily driven by improvements in net working capital in the quarter. We repurchased $117,000,000 of shares in the quarter and paid $19,000,000 in dividends.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

In the first half, we returned $316,000,000 or 138% of our free cash flow through dividends and buybacks to shareholders. We ended the quarter with $489,000,000 in cash and marketable securities. Now turning to Q3. Q3 sales are expected to be between $710,000,000 and $770,000,000 Third quarter gross margins are expected to be at 56.5% to 57.5. Q3 OpEx is expected to run at 36.5% to 38.5% of third quarter sales.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

The non GAAP operating profit rate at the midpoint of our third quarter guidance is 19.5%. The Q3 tax rate is expected to be 16.3% on a GAAP and non GAAP basis. The increase in rate is driven by the impact of the new tax legislation, which goes into effect in Q3. Hence, a year to date catch up is included in Q3. A full year tax rate is expected to be 14.5%.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Q3 non GAAP EPS is expected to be in a range of $0.69 to $0.87 on 158,000,000 diluted shares. GAAP EPS is expected to be in the range of $0.62 to $0.80 In terms of guidance, we will continue to guide one quarter at a time. Summing up, we delivered sales and earnings above the midpoint of our guide. We feel more confident in our near term outlook than we did ninety days ago. Looking ahead, our visibility is improving, driven by demand in artificial intelligence in both SoC and memory.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Second half of the year is shaping up to be stronger than the first half as we expected earlier in the year. Our multiyear investments in testing artificial intelligence are beginning to deliver new opportunities and accelerating top line growth. We are confident in the long term growth drivers of AI, electrification and verticalization trends that will drive our business in the coming years. With that, I'll turn the call back to the operator to open the line up for questions. Operator?

Operator

Thank you, The first question we have comes from CJ Muse of Council Fitzgerald. Please go ahead.

CJ Muse
Senior Managing Director at Cantor Fitzgerald

Good morning. Thank you for taking the question. I guess first question, your tone on your outlook clearly much more positive versus three months ago. And curious, is that a reflection of a pickup in business that you're seeing today in the second half? And is there any way to sort of frame whether growth continues into Q4?

CJ Muse
Senior Managing Director at Cantor Fitzgerald

And then perhaps more importantly, is it also related to new design wins that give you confidence beyond 2025?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Hi, CJ. It's Greg. Yeah. So it is the confidence is definitely related to an uptick in demand, primarily in AI compute, both in SOC and in memory.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And we expect that to, you know, it's it's a, the major driver for our q three guidance, and it's also the reason for our optimism about the full year. As as, I said earlier in my remarks, a lot of the programs that were designed into are occur the ramps are occurring late in the year. And so the split of demand between q four and q one is a real x factor. We know we know the demand's there. We just don't know the exact timing of it.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And your your other question in terms of the for the second half of this year, is this related to new wins or existing programs? I would say that many of the things that we're seeing in the '25 are actually wins that have occurred mainly in '24. You know? So in memory and in SOC, there are customer wins that we achieved either, you know, in '24 or early in '25 that are ramping. There are more opportunities in the funnel that we're hoping to close before the end of the year, but we would expect those to have a more positive impact in '26 than in '25.

CJ Muse
Senior Managing Director at Cantor Fitzgerald

Very helpful. And then I guess a follow-up to that. As you look to 2026, is there a framework for thinking about AI contributions to you and segmenting between custom silicon, networking, HBM and other?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

You know, looking out into 2026, we haven't done that analysis in terms of how that demand is going to segment. I think the you know, in general, we would expect the same kind of a split in the memory market that we're seeing now with, you know, kind of between, you know, 8595% of the memory market being driven by DRAM and most of that being driven by cloud compute AI applications.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

In the SOC market, looking into 2026, we had a lot of strength this year both in VIP compute and also in the networking part of compute, and we would expect that that's gonna continue into 2026. We're hopeful that we're going to be able to add in additional compute revenue from the merchant suppliers, but that's you know, that is an opportunity, not not something that we have in the bank right now.

CJ Muse
Senior Managing Director at Cantor Fitzgerald

Thank you.

Operator

The next question we have come from comes from Timothy Ouchi of UBS. Please go ahead.

Timothy Arcuri
Timothy Arcuri
Managing Director at UBS Group

Thanks a lot. So, Greg, you you for the robotics business, you you I think you said you talked about a plan of record, opportunity, and you're opening up, opening up a manufacturing facility in The US, which given how bad the business has been, you must feel pretty good about how big that opportunity can be. And they've I believe this customer has put some stuff on their website. So, so can you just help us, like, size how big that can be and sort of when it starts to impact your business? I think you said it's gonna be a, quote, significant growth driver for next year.

Timothy Arcuri
Timothy Arcuri
Managing Director at UBS Group

Can you just help us, give us any color on that?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Yeah. So the, you know, from the the the statements that I made in terms of establishing manufacturing in The US, it's for us, that opportunity is, at first, primarily driven in in The US, North America more generally. It has the opportunity to spread into other regions as well, but we're able to serve the European region from our Denmark manufacturing quite well. I do wanna emphasize that one of the things that is a requirement for many of the larger customer opportunities that we're pursuing, including the one that we won, is supply chain resilience that, these these manufacturers want to see that you have multiple production facilities so that they're gonna be able to get their material no matter what. So, we believe that having a geographic diversity in our supply in our operations is kind of a key element of this large customer strategy in general.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Now specifically around this one opportunity, the the solutions are largely developed, but there's a lot of kinda new product introduction work that has to happen in 2025. And so the demand associated with this opportunity in 2025 is gonna be quite it's not gonna be it's not gonna have a material effect on our robotics results. When we get into 2026, I can't give you an exact number, but, it will represent a, you know, a sizable fraction of the UR business, and, you know, and UR is the majority of the robotics business. So it's it's definitely a needle mover in '26, but I can't give you an exact number.

Timothy Arcuri
Timothy Arcuri
Managing Director at UBS Group

Okay. Awesome. Thanks. And then, just on the I I know you're not that excited about the opportunities in, you know, mobile this year, but it does seem that your big mobile customer, they're moving to a new package next year. And what is your assessment sort of on what impact that's gonna have on test times?

Timothy Arcuri
Timothy Arcuri
Managing Director at UBS Group

Obviously, you have, you know until you have transistor density going up, and test times seem like they're gonna also go up. So I know you saw the, you know, modem test orders this year, but does it make you optimistic about the about your, you know, mobile market and your large customer in particular next year? I know you haven't been that opt that optimistic, you know, lately, but I wonder if you can comment on that.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Yeah. So, you know, we've we've talked about the drivers for demand in the mobile space that there's unit volume, that there's device complexity, and, you know, and yield, you know, the the yield and utilization, sort of the efficiency of the of the process. On complexity, two nanometer gate all around is definitely going to enable significant increases in, like, transistor count kind of complexity. The the parts are gonna be more complex. The other thing that drives complexity is the the packaging methodology and the and things like the memory bandwidth.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So if, for instance, there are wider buses between the the processor and memory, that means that you'll consume more tester resources per device than you would if the buses were more narrow. So in addition to the just the transistor complexity, if the device needs more tester resources per device, you can test fewer devices at the same time. And that would be another way that it would you know, that would come through in the in our model as an increase in complexity. So going into 2026, we think that there is, you know, a potential inflection in transistor complexity. We also believe that there's a potential inflection around, memory memory technologies and packaging.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And so that makes us, you know, optimistic that mobile will be better next year. The thing is that mobile is going to be a smaller part of our overall mix in 2026 because of the strength of compute. So it's, you know, like, the if if mobile gets bigger, it's gonna be under as a a part of a more balanced mix than it was in our past.

Timothy Arcuri
Timothy Arcuri
Managing Director at UBS Group

Got it. Okay. Thank you.

Operator

Thank you. The next question we have comes from Mehdi Hussini of SIG. Please go ahead.

Mehdi Hosseini
Senior Equity Research Analyst at Susquehanna International Group

Thanks for taking my question. Greg, I just wanna follow-up to the last statement that you made. And I'm looking at the trend, and to me, 2026 could be an inflection inflection point in both mobile catalyzed by two nanometer and increased complexities as well as the Teradata's ability in scaling AI. And then the robotics, which is a a second derivative beneficiary of AI, from AI to IA. And I'm not asking for a guide.

Mehdi Hosseini
Senior Equity Research Analyst at Susquehanna International Group

We all understand that you have a 2028 EPS target. But if if all of these inflection points were to start happening in '26, we could see the mix changing, and we could see, finally, a strategy coming together. Am I thinking about this, Ravi? And I have a follow-up.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Yeah. No. You're you're thinking by the way, I love your optimism. The our strategy is to drive growth across all of our businesses, you know, between in Semi Test, all of the different parts of Semi Test compute, auto industrial, mobile, memory, we believe that we are positioned for growth across the midterm for all of them. Some of them because that end market is growing very, very strongly and others because they're positioned for a cyclical recovery.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Our IST business, we believe we're positioned for growth because of the growth in HDD bit, you know, HDD bit growth, the rise of SSDs, the fact that SLT is gonna be needed for AI accelerators, and the fact that we're gaining share in the mobile space. So we believe that's going to grow. Our product test group is positioned for growth through the midterm across all of the different units inside of inside of the product test group, including the new addition, Quantify Photonics, which we think is positioned for strong growth. And then robotics robotics, we are pivoting to segments that have higher growth, and we are pivoting the organization to be able to effectively serve large customers and winning those customers. So, you know, our our plan has a fair amount of resiliency in terms of, the sum of the parts is greater than the whole.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

But there is uncertainty in terms of how fast those things will go.

Mehdi Hosseini
Senior Equity Research Analyst at Susquehanna International Group

That's fair. And, Moiv, after near term, last night, one of your key HDD customer guided to almost a doubling in CapEx. How should we think about the system level test and if there is a uptick in STD test catalyzed by a new technology, HAMMER? Is this gonna be an immediate impact, or is it gonna take some time for you to actually see it?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

I think it's gonna take some time. That, first of all, the the in that market, the those the the testers that we build actually have a there's a relatively long lead time. They are, you know, built to order, and, installation takes a little while. So it's not like, we're not gonna crank out a 100 of these things in a quarter. We do believe that demand is going to be strengthening through 2026, but you also have to remember that there was huge amounts of idle capacity in the HDD market that, you know, is being filled more by the the the increase in test time of drives than volume of drives.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So, we're actually kinda hopeful about the transition to HAMR and, similar technologies from other other HDD manufacturers, because those those drives take longer to to go through the test and configuration process. But I think, you know, generally strength drink generally strengthening through 2026, but it won't you won't see a doubling like you saw from in terms of the capital budget for the player.

Mehdi Hosseini
Senior Equity Research Analyst at Susquehanna International Group

Okay. Thank you.

Operator

Thank you. The next question we have comes from Vivek Arya of Bank of America Securities. Please go ahead.

Vivek Arya
Vivek Arya
Managing Director at Bank of America

Thank you for taking my questions. For the first one, Greg, I was hoping you could help quantify how much how large is your AI compute business in q two. So if your SOC was about 400,000,000, how big is AI compute? And if you could help break it between compute and networking. And you mentioned new opportunities.

Vivek Arya
Vivek Arya
Managing Director at Bank of America

I assume you're referring to the potential to to be part of the GPU testing side. What needs to happen for you to get get more confidence? And if it does happen, is that a 26 or a 27 contributor? So just some quantification and then GPU time line. Is it 26 or 27?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So why don't we take those in backwards order? I'm gonna I'll I'll try to answer the the GPU related question, and I'll hand it off to Sanjay around the sort of the q two breakdown. So the what has to happen for us to gain share in the merchant compute space? Basically, right now, we have to execute, and we have to prove that our our test capability is equivalent, that we provide the equivalent quality, and we provide superior value. And we believe that we are on a track to be able to accomplish that.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

We in terms of timing, I would expect that if we are successful, that this will have a a modest positive impact in 2026, and it has the potential to build over time. There's a you know, when you are working with a customer that is implementing a dual vendor strategy, typically, they will need to continue to buy capacity from their their prior sole source for a period of time as they increase the number of devices that are tested on a new platform. So, we think that this is a you know, the the the good news is this puts us on a level playing field for new devices, and we believe that we have a differentiated product that we're playing with. So, we think that we we're very optimistic about where things are gonna go, but I think it it's to remember that it takes time to shift test strategy at customers of this size.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

And then on the first question, you know, in round numbers, the compute was, as part of SOC, was roughly about 20%, and it was a key driver of growth in Q2 versus expectations. And as Greg noted prior, we're seeing significant traction in the back half of the year where compute, I'll add memory in there, is gonna be the majority of revenue in semitask.

Vivek Arya
Vivek Arya
Managing Director at Bank of America

Got it. And for my follow-up, Sanjay, how much did Quantify Photonics contribute to q two, if any, and how much are you assuming in q three? I assume you include this in AI compute. And I know you're not giving a specific number for q four, but based on, you know, everything you're suggesting, is it reasonable to assume that q four, you know, perhaps grow sequentially and year on year to give Teradyne, you know, at least some modest top line growth overall for '25? Thank you.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Sure. So just Quantify Photonics, which we closed May 30, is actually in the product test group. We're not breaking those numbers out, but, you know, we've had it for about a month of the results. Regarding the the growth in compute, you know, we're we're not providing a a q four. But but generally speaking, yeah, we we are seeing incremental growth.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

You know, as Greg noted in his prepared remarks, we're seeing program launches toggle or straddle between q three and q four as well as q four and q one. But but it's our expectation that, you know, there'll be significant growth q three over q two and then q four over q three as well.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And just to to also, I think what you said in terms of, significant growth for q four year over year, I think that's right. I think that that definitely this q four is gonna be stronger than twenty twenty four's q four.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Yep.

Vivek Arya
Vivek Arya
Managing Director at Bank of America

Sorry. I meant overall for the company, not just the compute side. Like, an overall Teradyne sales in q four.

Greg Smith
Greg Smith

Thank you. The next question we have comes from Jim Schneider with Goldman Sachs. Please go ahead.

James Schneider
James Schneider
Analyst at Goldman Sachs

Good morning, and thanks for taking my question. I was wondering if you could maybe first talk about the trends, Greg, you outlined before relative to mobile SoC and when that could recover. In terms of that recovery, do you think that's at earliest likely to happen in a meaningful way in sort of the 2026 as we as you sort of prepare for those product ramps, or it could happen a little bit sooner than that?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Well, the typical the the typical mobile pattern is capacity adds in q two and q three. That is not a hard and fast rule, and it has a lot to do with, you know, sort of the the loading of testers through the year. So if there is sufficient capacity, then we'd see the demand drifting towards the second half of the year versus being in the early half of the year. We'll be able to give you big more color about that kind of early in 2026 as we get more firm forecasts about the demand. But right now, I think it's definitely more of a second half thing than a first half thing.

James Schneider
James Schneider
Analyst at Goldman Sachs

Thank you. And then as a follow-up, can you maybe just kind of talk about as you continue to ramp the compute SoC business in the back half of this year, is there any impact on the gross margin line, either positive or negative in terms of the mix of that business contribution above and beyond just the absorption piece?

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

Yes.

Sanjay Mehta
Sanjay Mehta
VP & CFO at Teradyne

So I think overall, as volume scales up, we'll generally get some efficiencies. But I will remind you that or as you recall, it's our product margins are really driven by tester configurations. And we operate the business model at the overall portfolio of about 59%, 60%, And we do expect that we'll continue to operate in that level.

James Schneider
James Schneider

Thank you. The next question we have comes from Samik Chatterjee of JPMorgan. Please go ahead.

Samik Chatterjee
Samik Chatterjee
MD & Equity Research Analyst at J.P. Morgan

Hi. Thanks for taking my questions. Maybe just going back to the opportunity on the GPU front that you're looking to execute on and totally understand you're saying it is more modest in 2026 if you're successful and ramps up over time. In the past, you've quantified the VIP. Is it compute TAM for us, 300,000,000 going to $800,000,000 How should we think about the size of the test equipment market when it comes to GPUs?

Samik Chatterjee
Samik Chatterjee
MD & Equity Research Analyst at J.P. Morgan

I think that you historically excluded that because you didn't have a seat at the table, but how should we think of the magnitude of that opportunity, which can sort of translate over time? And I have a follow-up. Thank you.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So in terms of the merchant AI accelerator space and and, you know, so GPUs in general, that's that's big. I mean, it is the majority of the compute TAM In, you know, in general terms, we're probably looking at you know, in back in 2024, there was about $2,300,000,000 of compute. And, you know, so it making progress into merchant merchant compute taps us into a pretty big pool. You know? So, you know, probably in the neighborhood of, you know, two x the size of the VIP compute out in the later parts of this of the term, probably more than two x the VIP compute.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So getting a share of that is gonna be a positive impact.

Samik Chatterjee
Samik Chatterjee
MD & Equity Research Analyst at J.P. Morgan

Got it. Got it.

Samik Chatterjee
Samik Chatterjee
MD & Equity Research Analyst at J.P. Morgan

Thank you. And then maybe for the follow-up, for the large customer that you have the plan of record on for the robotics business, I know you said you this year robotics, you expect it to not be breakeven, but is that embedding some of the cost relative to supporting sort of the product related expenses for this new program? And does that give you better leverage on the operating line on the robotics segment as you go and sort of get that revenue next year? Just trying to understand when the expenses rate was supporting that program are largely expected to hit. Is it this year or next year? Thank you.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So, but, yeah, as I said, the the revenue impact is gonna be positive in 2026. There are some expenses that we're taking in 2025, mostly associated with establishing manufacturing in The US. That is not specifically for one customer, but certainly, we will see benefits from being able to do that manufacturing in The US for that and other opportunities. So the the term leverage is good that as our robotics volumes increase, since we are internally manufacturing most of most of robotics, we will be able to absorb our fixed costs associated with operations as our volumes go up, and we would expect to see absorption having a positive effect on gross margins. So we'll have to see how that develops, but there's definitely a few of the expenses that are going to come in, in the second half of this year.

Operator

Thank you. Next question we have comes from Atif Malik of Citi. Please go ahead.

Atif Malik
Atif Malik
Director - Technology Equity Research at Citigroup

Hi. Thank you for taking my questions. Greg, you talked about HBM memory snapback in second half. In the past, you guys have been of of the view that the TAM is more flat this year because of high productivity of your testers. So what has changed?

Atif Malik
Atif Malik
Director - Technology Equity Research at Citigroup

Are you more optimistic on new HPM qualifications in Korea, or is it HPM four that's driving the improved outlook?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So just to be clear, the snapback that I'm our view of sort of how the memory market is shaping up for 2025 is not has not changed that much. My comment about snapback was really in terms of the timing of quarterly revenue. And so, you know, we had a we had a low quarter for memory this this quarter at 63,000,000. We we are expecting that the overall TAM for memory is is kinda stable, and the the demand that's coming in for HBM is going to be definitely, you know, primarily in Q4 of this year. And there's some uncertainty in terms of the timing of ramps between Q4 of this year and Q1 of next year.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Because especially for HPM four, there are only certain devices that are designed for it. You know? So it's not it the h b m is not at the point like DDR where there it's a commodity and used across a number of a lot of different designs. There's a high linkage between particular AI accelerators and particular generations of HBM. So that is the thing that's gonna be driving the those ramps.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So I do think that the the majority of capacity demand in 2025 is going to be adding capacity for for HBM four.

Atif Malik
Atif Malik
Director - Technology Equity Research at Citigroup

Understand. And then in response to an earlier question, you mentioned that, you know, complexity is gonna be your friend on the mobile side as the packaging moves from integrated fan out to wafer level multichip modules. There there's also discussion going on on substrate less packaging for new AI chips in the next two to three years. And and and I was hoping that you can kinda pull the curtain a little bit on your optimism around the merchant GPUs. Is that packaging technology the the driver where you feel like you can insert your testers?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

No. I think that I mean, we're in general, changes in packaging strategy generally are driving our customers to invest more in wafer level test of their devices so that they have less fallout further down the line. But the opportunities that we have to compute to compete in new parts of compute have a lot more to do with those those customers seeking to to have more resilience in their supply chain and more ability to, you know, take advantage of the technology that each of the tester companies brings to bear. So it's, you know, like, the the the opportunity isn't hinging on, like, a new technology or an introduction of a new device generation. It's definitely more around an operation strategy for these companies.

Atif Malik
Atif Malik
Director - Technology Equity Research at Citigroup

Got it. Thank you.

Thank you. The next question we have comes from Krish Sankar of TD Cowen. Please go ahead.

Krish Sankar
Managing Director at TD Cowen

Yeah. Hi. Thanks for taking my question. Gurig, I had two of them. First one, on the GPU test win, did you having the networking business help with the GPU side, or was it more of a direct comparison and value proposition with Advantis?

Krish Sankar
Managing Director at TD Cowen

And also, how to think about potential share gains on the ASIC side as well where Advantage has been a legacy test supplier?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So first of all, it isn't a win yet. So just to make sure that we're we're staying on the same page, we have we have an opportunity to compete in parts of the market where we haven't had that opportunity before. It is, you know, in general, having you know, serving a customer in another segment allows you to establish reputation and allows you to compete in other parts of that customer's business. And, you know, we feel like in customers that do business with Teradyne that that reputation helps us. We think that that opens doors and allows us to, you know, certainly demonstrate capabilities of our equipment and our team.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So I I don't wanna go into more detail around any specific customer. Now in terms of share of ASIC, the the the market is becoming for VIP compute, the market is becoming much more complex. When the VIPs or the hyperscalers were in their first generation of parts, they were definitely following the guidance of their design aggregators. You know, they were like, whoever their foundry or the design aggregator was saying, you should test your part on this platform. They were pretty much doing that.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And as they have ramped, as they have, increased the volumes of their parts and increased the expertise of their internal teams, they're taking more and more control over the test strategy and the operation strategy for these devices. And so our you know, we are definitely doing our best to increase share at the design aggregators, but most of our energy is going into kind of the two ends. The the people who actually buy the testers, the foundries and the OSATs, demonstrating that we have a better platform, a platform that will help help them make better margins. And then for the the specifiers, the hyperscalers, the VIPs that are making these test strategy decisions that they're gonna be able to get their parts to market faster and more effectively on our platform than the competitions. So the power started in the middle, and we believe that it's migrating towards the two ends.

Krish Sankar
Managing Director at TD Cowen

Got it. Very helpful, Greg. And then just a follow-up of the robotics win. Is there a way to size it in terms of the number of units you'll be shipping either in 2026 or longer term? And, also, are you just providing the arm or even the sort of the bells and whistles like the grippers, vision, etcetera, for this big robotics win?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So I can't give you exact numbers around units. And over time, as as we get further into that program, we may be able to provide more information. But right now, we're it it just we're gonna have to we're gonna have to wait and see. A lot of things depend on not just us, but also how, quickly and effectively the technology can be introduced across, you know, sort of thousands of locations for this customer. So, I I I would hesitate to to put a number on it.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

There are some interesting analyses that have been done, that I think, are using the right methodology, but there are pretty big error bands around it. And to answer your other question, we are we are the we are providing the arm. In terms of the, like, the deliverable hardware, it's really the arm and the, call it, the robotic software platform. You know? And so, other other software, other, end of arm, tooling is being added.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Vision, all of that is being done by the end customer. And so our business is primarily around the arms themselves and the support and service of those arms.

Krish Sankar
Managing Director at TD Cowen

Thanks a lot. That's very helpful.

Operator

Thank you. The next question we have comes from Brian Chin of Stifel. Please go ahead.

Brian Chin
Brian Chin
Director at Stifel Financial Corp

Hi. Good morning. Thanks for letting us ask a question or two. Greg, maybe just to kind of frame and contextualize some of this. Taking a step back, how are you sizing the overall compute TAM this year?

Brian Chin
Brian Chin
Director at Stifel Financial Corp

And also a subsegment of that, the VIP SAM, again, inclusive of those AI related ASICs and TPUs. I think in the past, earlier this year, you referenced sort of a $2,300,000,000 for the compute market, 400,000,000 for VIP. I know those numbers have probably uptick since then. Can you maybe sort of provide some color? And also, do you expect to perform at sort of a 50% share of that VIP SAM?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Hi, Brian. So as I as I said, a lot of the VIP compute is kind of perched in q four and bridges q four and q one. So the VIP TAM is really tough to call for 2025. I think, you know, you what you said is that, there's probably upward upward pressure. I would agree with that, that there's probably some upside to last year's 400.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And in terms of, like, referencing the ComputeTam for last year, I believe that there's also significant up this year, you know, especially in the merchant merchant GPU space, it's pretty clear that the TAM is gonna come in higher, but we're not providing an estimate for the TAM right now.

Brian Chin
Brian Chin
Director at Stifel Financial Corp

Yeah.

Brian Chin
Brian Chin
Director at Stifel Financial Corp

Yeah. Got it. The the is that I guess, one hand, does that, provide some sense that, like, networking is a very big component in some of this improvement as well as on the memory side in terms of some recovery or pickup on the HBM for, test and new new test insertion activity?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Oh, yeah. Networking is networking is a an important part of our compute revenue in 2025. Certainly. Maybe just And and it and it has it has strengthened from where we expected at the beginning of the year.

Brian Chin
Brian Chin
Director at Stifel Financial Corp

Yeah. Got it. Okay. That's helpful. And then just kinda lastly, the as a follow-up.

Brian Chin
Brian Chin
Director at Stifel Financial Corp

Would you attribute any of the uptick in in test utilization rates to any pull forward of of supply chain activity?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

No. It's I you know, the the pull forward has shown up in some of our customers' results, but those customers were pulling forward demand in an an environment where they essentially were able to push up utilization versus adding significant capacity. So I it it certainly I don't think it's had a meaningful effect for us.

Brian Chin
Brian Chin
Director at Stifel Financial Corp

Okay. Great. Thank you.

Operator

Thank you. The next question we have comes from Shane Brett of Morgan Stanley. Please go ahead.

Shane Brett
Shane Brett
Equity Research Analyst at Morgan Stanley

Thank you for taking my question. I just wanna clarify on the GPU customer question from earlier. You said you don't have the win yet, but the tone from the call has been you're very confident that you will. Could you just level set on whether these wins beyond networking are looking concrete, or are we still kind of in discussion with that customer? Thank you.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

I don't I don't know that I can put odds on it. I I believe that we have strong sponsorship from the customers where we're competing, that they they want to execute a strategy that gives them more resilience in their supply chain. So I, you know, I when we when we set our minds to something, we we tend to succeed at it. But I don't want to I certainly don't wanna claim something as one when it isn't one. You know?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So I I I don't know if that's helpful, but, you know, we are we are proceeding on the you know, with every intention to be successful in these in these design ins. But until you actually have the part in production, you have to be careful about, you know, what adverse factors you can't you can't can you can't predict. The other thing is that we've definitely seen over time that, the amount of sort of how long it takes to go through the qualification process can vary by a lot. And so trying to call the timing of it is also a challenge. But I, you know, I I think we are very happy that we have an opportunity to compete for stuff that we haven't had the opportunity to compete for for twenty years.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

But we are you know, I can't guarantee that we have a win.

Shane Brett
Shane Brett
Equity Research Analyst at Morgan Stanley

Thank you. That's very helpful. And my follow-up is so you spoke about VIP driving compute revenues here. Could you just talk about the kind of customer breadth you're seeing there and just visibility towards further market share gains with those customers? Thank you.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Well, you know, the one of the one of the key trends that we identified was verticalization. And there aren't all that many gigantic hyperscalers in the world. And their their importance in this space is kind of directly proportional to their capital spend on data centers. You know? So it also has a great deal to do with the number and the number of chips that they're designing, the different chips that they're designing, and the applications that they're going into.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

The real prizes in this space are the the CPUs and the GPUs. The CPUs are the ones that are being developed by the hyperscalers, the VIPs in general. They're ARM based, and, you know, they have a very high volume because they're, you know, pervasive across data centers. The AI accelerators are also very important to win because they have so much so much complexity, a lot of test intensity to them. So to answer your question directly, our VIP compute is driven by a few customers, not a single customer, and certainly, you know, it's, like, less than six, more than one.

Shane Brett
Shane Brett

Thank you. The next question we have comes from Steve Steve Badger of KeyBanc Capital Markets. Please go ahead.

Steve Barger
Steve Barger
MD - Equity Research at KeyBanc Capital Markets

Thanks. Good morning. Greg, you talked about the consolidation of customer facing functions in robotics. Was that 9% growth primarily a function of that change, or were those deals already in progress? Just trying to get a sense for how quickly that change can drive sustainable improvement in sales.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So the with the magnitude of the restructuring, we were really pleased that robotics was able to deliver quarter on quarter growth. That said, we typically see a stronger q two than q one. You know? So the the thing that I was trying to communicate was that the restructuring was executed successfully, and it didn't significantly it didn't have a significant negative impact on our results in q two. I think that we are going to the the positive impact of this restructuring in terms of combining sales, combining service.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Combining sales, we're gonna be giving our partners a broader product line to be able to sell and our sellers a broader broader product line to be able to represent. You know? So we believe that that is gonna be a top line positive. And by combining service, we're gonna be able to offer more consistent and better package service packages for our customers that buy both kinds of robots. I would expect that the positives from this restructuring are gonna play out in 2026, not in 2025.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

That in 2025, we're really focusing on the new product introductions and the large customer wins that we're that we are that we have achieved and that we're trying to achieve in the back half of the year. It's it it was a big change, and we are really pleased that it went as well as it did.

Steve Barger
Steve Barger
MD - Equity Research at KeyBanc Capital Markets

Got it. And if if this change really does cause robotics to turn the corner in 2026 along with the the plan of record that you talked about, Can you talk about how you plan to build internal manufacturing capacity to, will that are you gonna build the where you see future demand or some will some of this be fulfilled by EMS companies? And what level of sales do you wanna capacitize to?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So we have a significant amount of production capacity. So we you know, the the reason that we are doing something in North America is around operations resilience and customer intimacy more than trying to really, like, meet up to immediate demand. In in the answer to your question in terms of internal operations versus EMS, our strategy in in Europe and The US is primarily around internal. And our strategy in APAC, if we as we localize production, would probably be to utilize partners there because they're gonna be able to localize the supply chains more effectively than we could. So we'll have a blended strategy between internal and outsourced manufacturing for robotics.

Steve Barger
Steve Barger
MD - Equity Research at KeyBanc Capital Markets

Got it. Thank you.

Thank you. The next question we have comes from Gus Richard of Northland Capital Markets. Please

Gus Richard
Managing Director at Northland Capital Markets

Just in terms of China as, you know, the domestic Chinese semiconductor industry grows and you have more fabless and IDMs there, you know, how is that impacting your business, particularly as it pertains to industrial and auto?

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So right now, the the market in China, if you look at the ATE market in China, the there is a portion of that market that Teradyne cannot serve because of trade regulations. If you leave that aside, the remaining market is the biggest part is Chinese memory manufacturers, and our share in Chinese memory manufacturers is actually kinda higher than our average memory share worldwide. So we compete very, very well there. The the rest of the SOC market in China, there's there's you know, just like everywhere else, there's compute, there's mobile, and there's auto and industrial. And we are competitive in all three of those spaces.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Most of the local competition in in terms of ATE in China is really focused at the the in the auto and industrial space. So we have we have significant competition, and we tend to focus on the higher volume, higher quality suppliers in the space, because they value the throughput and the accuracy that our equipment has.

Gus Richard
Managing Director at Northland Capital Markets

Got it. Super helpful. And then just in terms of of robotics, you know, one out of two robots in the planet is installed in China. You know, the EV market is shifting to China and and production. And I'm just wondering, you know, again, you know, is your your SAM shrinking because of that, you know, transition to manufacturing in China of of autos and, you know, a little bit of color on how competitive the Chinese manufacturers of robotics have have or have not become.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So there is a very there are a number of competitors in the cobot space and the AMR space in China, and they have they have good products. We believe our products are better. They also have great customer intimacy in that market. You're right that over the you know, from 2018 to now, the growth rate for the cobot market in China has been kinda twice the growth rate of the the cobot market outside. The Chinese automaker and so we're we're very focused on trying to compete in China and to make sure that we maintain and grow our share in that market.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

But it is it is highly competitive. The Chinese, you know, so I would say the Chinese auto manufacturers are definitely offering great products in EV, and they are growing faster than automakers in other parts of the world. But I am not sure if that is sort of an inevitable trend or if we'll see changes in the auto industry in The US and Europe and in terms of localization that that sort of confuse that situation going into the next couple of years.

Gus Richard
Managing Director at Northland Capital Markets

Got it. Thank you.

Thank you. The final question we have comes from David Dali of Steelhead Securities. Please go ahead.

David Duley
Managing Principal at Steelhead Securities

Yeah. Thank you for squeezing me in. Much appreciated. I also have a question on the GPU space. After the analyst day, it seemed like, you know, your opportunities to break into GPU tests were based on, you know, a combination tester with silicon photonics and, you know, you closed your QuantiFY acquisition.

David Duley
Managing Principal at Steelhead Securities

So I guess the first part of my question is, when can we expect a kind of a combo product that can do electrical and optical test? And the the second part of the question is, it sounds like you also have another cut in opportunity with the big GPU guy. And I'm wondering, you know, the key reason that why that is competitive wise. Is it because you have twice the throughput or which would obviously make your economics much better than your competitor? Or or why is there why is there an earlier cut in point besides silicon photonics, I guess, is really the question.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Okay. So, in answer to your first question, Teradyne is already delivering a, electro electro optical test solution. Right now and over the, you know, over the next twenty four months, that solution is going to incorporate more and more of the quantified photonics instrumentation. And we expect that that part of the market is gonna grow, and we expect that that having a superior solution in that space will allow us to grow share in the AI accelerator space, both merchant and VIP. Now in terms of why is there an opportunity in GPUs before that, I think it has it's mostly to do there are two things going on.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

The reason that the opportunity is there is because of customers' desire to have more resilience in their supply chain. That's that's why we were invited to the dance. Now that we've been invited to the dance, now it is our you know, like, our level of success is going to be dictated by the differentiation of our product offering. And that is you know, we believe that we have advantages in throughput, in reliability, and in time to market. But that's exactly what we have to prove, and the degree that we prove it will have an influence over how quickly we are able to penetrate those accounts.

David Duley
Managing Principal at Steelhead Securities

Okay. Great. And then my second question is, could you just elaborate a bit more? You talked about an another HBM win on the at the staff level, and it sounded like you're talking you're describing a an another another insertion point. Could you just kind of, like, take a step back and help us understand, you know, the the number of insertion points for HBM currently and and, you know, how you play in that space? Just to kind of Sure. So Yeah. Thank you.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

It it like, thanks for, like, unleashing my inner professor Greg here. So let me just sort of take a take a step back. So an HBM an HBM memory stack has multiple DRAM die, right now eight going to 12, and then a base die.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

Each one of those memory die and the base die go through a wafer level test. Once that wafer level test happens, then all of the DRAM die are diced up, and they are assembled down on top of the wafer of base die. Okay? So now you have a wafer that has a bunch of HBM stacks on it. And then after those stacks go through, you know, so the first test is at the wafer level.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

The second test is after the HBM die gets stacked on the base die. So we call that, you know, post stack wafer test. And then the current production methodology is you chop up that wafer of stack stack dye, you pack it up and you send it off, and then you assemble it into an AI accelerator. What is happening is that, after those AI accelerators have been assembled, they're actually seeing significant yield fallout due to HBM problems. And so what they're trying to do is they're trying to decrease the number of defective HBM stacks that get installed in these accelerators.

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

And so the thought is, if you do a test step after you cut that HBM stack die wafer into individual HBM stacks, you're gonna be able to catch a set of faults that you didn't see before. And so there are there are suppliers in this space that are experimenting with adding that step to see if it has an and improves quality.

David Duley
Managing Principal at Steelhead Securities

Greg Smith
Greg Smith
President, CEO & Director at Teradyne

So I just want to add a final thought. AI, you know, as we talked about in our Analyst Day, we believe that AI was gonna have a profound and positive impact on Teradyne's business. The investments that we've made in our SOC, memory and IST businesses to align with AI trends are now delivering new opportunities, socket wins and financial returns. We expect that the majority of our Semi Test revenue in the second half will be driven by AI applications, and it's clear that our momentum is building. I'd like to thank you very much for joining today.
