Q1 FY2026 · Earnings Call TranscriptMay 5, 2026

Operator

Thank you for standing by. Good day, and welcome to the Onto Innovation first quarter earnings release conference call.

Today's conference is being recorded. At this time, I would like to turn the conference over to Sidney Ho.

Please go ahead.

Sidney Ho

Thank you, Taryn, and good afternoon, everyone. Onto Innovation issued its 2026 first quarter financial results this afternoon shortly after the market closed.

Let me now turn the call over to your CEO, Mike Plisinski. Mike?

Michael Plisinski

Thank you, Sidney. Good afternoon, everyone, and thank you for joining us on our call today.

The Onto Innovation team is off to an outstanding start to the year as the momentum in our business continues to build in support of strong demand for AI compute. This surge in demand across both front end and advanced packaging resulted in first quarter revenue above our original guidance range and is expected to continue with a heightened outlook for the second quarter revenue, which at the midpoint represents a 20% increase year over year.

Momentum should continue into the second half of the year with rising customer expansions enhanced by accelerating new product adoption and a growing backlog, all indicating more than 15% sequential revenue growth in the second half of the year. In total, we expect revenue growth of more than 30% in 2026.

This momentum is driven by the insatiable market demand for high-performance compute and supporting process technologies, including silicon photonics. Customers benefit from our broad and synergistic portfolio of optical process control technologies, which, through our software, are capable of working together to provide more actionable intelligence to manufacturers.

The announcement of our strategic collaboration with a leader in X-ray technology, Rigaku, expands this capability significantly. While optical metrology is preferred for high-volume manufacturing, additional needs are emerging as manufacturers increase the application of exotic materials and 3D structures at transistor and chiplet scale, which is where the penetration power and precision of X-ray technology can provide additional information about material composition and underlayer data to potentially improve optical metrology robustness.

The key to realizing this benefit is our AI Diffract software, where our customers were the first to see the potential benefits of leveraging AI Diffract technology to unleash the strength of Rigaku's X-ray systems to solve process metrology challenges where other suppliers struggled. Now, with two competitive wins in hand and several other evaluations planned across memory and logic manufacturers, we are confident that the value of this combination to our customers will increase.

In addition to revenue from licensing AI Diffract to support Rigaku X-ray systems, another revenue stream involves the development of more complex hybrid metrology solutions to provide unique production-capable metrology by combining the strengths of optical and X-ray technologies. The breadth and depth of Rigaku's X-ray technology makes them an outstanding partner, as they enjoy one of the broadest portfolios of X-ray technology spanning CD, materials analysis, and films.

Rigaku has over 75-year history in X-ray with over $600 million in 2025 revenue, of which approximately 40% is related to the semiconductor industry. We're proud to be working together, and our investment of 27% of the business, which provides us a seat on their board of directors, will further strengthen our long-term alignment, provide deeper insight into X-ray technology roadmaps, and position us to jointly advance next-generation hybrid metrology solutions.

While the Rigaku partnership expands our opportunities for growth tied to future process challenges, today's process challenges are driving increased demand for our solutions in both advanced packaging and advanced nodes. Starting with advanced packaging, we're of course thrilled to have announced our qualification adoption of Dragonfly G5 inspection system at a leading 2.5D logic customer, closely following our wins in hybrid bonding with memory for both 2D inspection and 3D metrology.

Our team did a phenomenal job to accelerate the delivery of this completely new platform, which delivers improved sensitivity, high throughput, and the flexibility of multiple sensors to provide a compelling and differentiated value proposition to the customer. Shipments to customers are ahead of plan, and we are actively engaging with new customers and applications.

With a pipeline of over 15 distinct applications across over 10 customers, the outlook for Dragonfly G5 is very promising, providing opportunities for both share gains in current markets and expansion into new markets. Just as 2D features within die are shrinking rapidly, are the 3D interconnects between die.

2 years ago, the most advanced bumps were approximately 15 to 25 microns high. Today, we're sampling bumps below 6 microns in height.

This adoption of smaller, more dense bumps plays to the strength of our 3Di technology and has led to several more OSAT customers and over 10 additional orders in the quarter. Finally, the strong demand for AI and the industry constraints in packaging capacity are causing customers to look at additional processes, such as panel-level packaging, where larger substrates can provide for greater economies of scale as the adoption of heterogeneous packaging drives larger package sizes.

We're pleased to learn the JetStep was recently qualified at two packaging suppliers to AI device manufacturers with ramp expectations in 2027. Considering all of these growth drivers, we believe our advanced packaging revenue will grow more than 50% in 2026.

Turning to our advanced nodes business, it continues to strengthen across both logic and memory. Adoption of our Atlas G6 platform is expanding, following successful competitive head-to-head evaluations at several key accounts for next-generation logic nodes, while in memory, we're seeing solid traction as DRAM customers ramp development of next-generation devices.

Additionally, we secured a new application win for TSV metrology using our Atlas system, with initial shipments expected to commence in the second half of the year. With this broad-based strength in logic, DRAM, and early signs of recovery in NAND, we now expect our advanced nodes business to grow approximately 25% in 2026, ahead of the average WFE growth expectations in the low 20s.

With that, let me now turn the call to Brian to review our financial highlights and provide second quarter guidance. Brian?

Brian Roberts

Thanks, Mike. Good afternoon, everyone.

As Mike noted, 2026 is off to a strong start for Onto Innovation, as we exceeded the high end of our first quarter guidance range across all key financial metrics, including revenue, gross margin, operating margin, and earnings per share. Revenue of $292 million increased nearly 10% sequentially on strength primarily across our advanced nodes business, highlighted by adoption of the Atlas G6, and our inspection products, including the initial commercial shipments of the Dragonfly G5.

Specialty device and AP was approximately $160 million in the quarter, of which two-thirds was advanced packaging, $25 million related to Semilab, and the remainder specialty device, including power semi. Advanced nodes was approximately $80 million, of which 60% was memory, primarily DRAM, and the remainder logic.

Software and services comprised the remaining first quarter revenue. Despite increasing headwinds around certain material input costs, such as memory and higher fuel and shipping charges, we demonstrated solid margin performance as gross margin improved sequentially by 110 basis points to 55.7%, and operating margin increased by 150 basis points to 26.7%.

Our performance reflects benefits recognized primarily from our move to extended factories. Earnings per share were $1.42, reflecting a 13% improvement over Q4 2025.

On April 20th, we announced the deepening of our strategic partnership with Rigaku, including the purchase of a 27% stake in the company from Carlyle Group for approximately $710 million. The deal is expected to close in the second half of 2026 and be primarily funded with cash on hand.

The strategic rationale, as Mike discussed, is clear. Let me take a minute to discuss the financial side of the transaction.

We will account for the purchase using the fair value option method for investments, which simply means the deal would be recorded at cost, and then each reporting period, we will show an unrealized gain or loss based upon the movement in Rigaku's stock price. This will be reflected in the other income section of our P&L.

While Rigaku's financials will not be consolidated into our numbers, we see three primary benefits which will enhance our financial results. First, Rigaku's X-ray tool integrated with our AI Diffract software will generate incremental licensing revenue to us at nearly 100% margin.

Second, we expect we will sell additional metrology tools, such as our Atlas G6, to customers who are using the integrated X-ray tool. Third, we expect Rigaku will continue to pay dividends to shareholders, which equates to approximately $7 million or more per year based on our expected ownership stake.

Within a year of the close of the transaction, we would expect that the income generated from these three sources will offset any forgone interest income on cash used in the deal. Now let me discuss our outlook for the second quarter and some thoughts on the remainder of 2026.

We previously announced on April 16th our Q2 revenue expectation of $320 to $330 million, representing at the midpoint a 10% increase to previous analyst expectations and 28% year-over-year growth. As we look to the second half of this year, revenue is expected to accelerate to at least 15% growth over the first half of 2026.

This translates to 2026 revenue greater than $1.3 billion. Alongside this outstanding revenue result is our expectations for continued second quarter gross and operating margin expansion.

While we do note increasing headwinds around certain material costs, fuel charges, and investments in our R&D and services teams to support the revenue ramp, we are confident in our ability to show continued margin expansion. We currently expect Q2 gross margin in the range of 56 to 56.5%, operating expenses of $90 to $92 million, operating margin in the range of 28 to 28.6%, and earnings of approximately $1.69 per share at the midpoint.

This assumes a non-GAAP tax rate of approximately 15% and slightly more than 50 million shares outstanding. While closely monitoring macro and micro headwinds impacting our cost structure, we remain confident that we will improve gross margins in Q3 and Q4 at a rate of at least 50 basis points per quarter and exit Q4 with an operating margin greater than 30%.

With that, let me turn it back to Mike for some closing thoughts before we take your questions. Mike?

Michael Plisinski

Thank you, Brian. In summary, this quarter underscores the strength of our execution and the accelerating momentum across our portfolio.

We exceeded expectations in the first quarter, advanced our leadership in advanced packaging with the successful qualification of Dragonfly G5 at multiple key customers, and took a major step forward in our metrology strategy through the partnership and investment in Rigaku. At the same time, our operational discipline continues to enhance scalability and drive strong margin expansion.

Our visibility continues to strengthen, supported by record backlog, new product momentum, and deep collaboration with customers as we work together to solve their most critical process control challenges. With this visibility, market expansion, and our relentless drive to improve operational efficiencies, we believe Onto Innovation is well positioned to not only outperform this year, but also carry that momentum forward into 2027.

Now, Taryn, let's open the call for questions from our covering analysts.

Operator

Thank you. If you are dialed in via the telephone and would like to ask a question, please signal by pressing *1 on your telephone keypad.

If you are using a speakerphone, please make sure that your mute function is turned off to allow your signal to reach our equipment. We ask that you please limit yourself to one question and one follow-up question.

Again, you may press *1 to ask a question, and we'll pause for just a moment to allow everyone an opportunity to signal. We'll take our first question from Craig Ellis with B.

Riley Securities.

Craig Ellis

Thanks for taking the question, and congratulations on the real strong execution, guys. Mike, I wanted to start with a question on Dragonfly G5.

Clearly, you got a marquee win that starts to ship in 2Q, which is great to see. Can you just talk about the way the pipeline allows for visibility for growth through the back half of the year?

Then, what are you hearing from customers with Dragonfly G5 relative to 2027?

Michael Plisinski

Great question, Craig. From the G5 perspective, one of the I think comments I made is that we're actually getting requests to pull in and serving those requests to pull in G5 shipments.

In fact, we've shipped several systems in Q1, be shipping more into Q2, and even more in Q3 and Q4. We see a steady growth in demand for the G5 throughout all four quarters.

That's an acceleration or a pull-in of the G5. From a perspective of 2027, from those existing customers, we certainly have visibility into stronger demands, as you would expect as they get cut in to production in '26.

As that production expands in '27, and that's what we're expecting. I also mentioned that we have a very strong pipeline of application studies, and I highlighted that these are both studies in existing technologies, existing markets we serve, as well as new markets.

Those applications are going quite well, which would imply, if successful and resulting in orders, imply significant expansion in 2027.

Craig Ellis

Very good. Then the follow-up question is on advanced nodes.

We're significantly raising our view for advanced nodes growth this year to 25%. Can you just talk about some of the end-use drivers for that and how we should think about linearity as we go through the back half of the year in '26?

Thanks, Mike.

Michael Plisinski

You're welcome. For us, the advanced nodes, the biggest driver is, of course, the Atlas OCD metrology and some of the latest capabilities we're providing customers is with smaller spots, being able to measure in the actual die to provide more process information that the customers can use to improve yield.

Historically, spot sizes were too large to do that, and you had to measure in some sort of test areas. Customers prefer to do it on die, if possible.

We're seeing good drivers from that. We also are working on the integrated metrology, and we've had some good progress in integrated metrology from logic customers building on the strength we have in the memory market.

That also contributes to some of the growth we're seeing, as well as in the films. The Iris films tools, we're seeing some level of growth there in the common films, but we continue to work with customers on the critical films as well and hopefully see that contributing to some exciting news more towards the end of this year and into 2027.

That's what we're seeing on the advanced node side.

Craig Ellis

Got it. Thank you.

Operator

We'll take our next question from Blayne Curtis with Jefferies.

Ezra Weener

Hi, Ezra Weener on for Blayne. Thanks for taking my question.

Just the first one, last quarter, you were talking about a big VPA potentially being two-thirds weighted into '27 and could get pulled in half-half, theoretically, into '26. Can you talk a little bit about what you're seeing in terms of demand from customers from a timing perspective, and if you're seeing pull-ins?

Michael Plisinski

Broadly speaking, we are seeing pull-ins, but not at the expense of the 2027 numbers. It's really more of a broader rising of the tide.

The pull-ins, if you look at '26 and '27, a lot of these expansions are tied to new fabs coming online versus filling up excess capacity in existing fabs. The pull-ins are if the customers are able to ramp up a fab quickly enough and they want to take some more tools, or we had some share gains and we see a share shift and they want to pull in some tools.

It's not at the expense what we see so far of '27. In fact, '27 continues to look much stronger even than '26.

Ezra Weener

Got it. Thanks.

Then just a follow-up. Dragonfly G5 was looked at as a margin improvement story versus G3.

Can you help kind of talk about how much you're seeing that actually impact margin?

Michael Plisinski

It's for sure going to be an improvement in margins. It's a completely new tool with a significant improvement in value proposition to the customer.

Overall, the cost of ownership is for the customer much more attractive. You're not going to see the margin improvement in the initial first half of the year because the relative volume is low as we continue to ramp it throughout this year, going into the second half.

Where I'd expect you to see a more significant impact is in 2027 when that transition to Dragonfly G5 is much more predominant, much stronger, and it's a higher percentage of the overall inspection revenue.

Ezra Weener

Got it. Thank you.

Michael Plisinski

That said, we do continue to expect to improve the gross margins throughout each of the quarters throughout this year.

Operator

If you find that your question has been answered, you may remove yourself from the queue by pressing *2. Once again, if you'd like to ask a question, you may join the queue by pressing *1.

We'll move to our next question from Edward Yang with Oppenheimer.

Edward Yang

Hi, guys. Thanks for the time, and congrats on the G5 foundry qualification.

That's a big win for you guys. Maybe Mike, can you give a little bit more detail on why the foundry customer liked the new platform versus other options?

Are you expecting any share recapture, new layer wins, or broader customer application expansion related to G5?

Michael Plisinski

I characterized it as a 2.5D logic customer. I didn't say foundry, per se, we'll just stick to 2.5D logic.

I do expect in the head-to-head, you have to win, and if you win, then you get more orders. That by definition means that we're going to see some opportunities shift back to us that were either served by us before or a new opportunities for us.

Again, driven by the higher resolution and the compelling value that the flexibility of the Dragonfly delivered to the customer. I think you also asked why the win.

Again, we've been in this market for a long time. Packaging is very different than the front end.

Our tool is designed for packaging. What we needed to do was deliver on the high-resolution piece.

We've done that. We are seeing things now below 200 nanometers, where historically 800 nanometers might have been about the limit.

This is a combination of new optics, new camera, new staging, basically a ground-up system, but leveraging all of our experience in the challenges in packaging with die warp, with wafer warp, with rough surfaces due to different types of CMP polishing, leaving rough surfaces for metal layers and things like this. All of our algorithms and experience helped to create a very compelling system.

In addition, we added some new capabilities: die-to-die algorithms that allow us to eliminate die variations. I think that's a significant improvement, complementary to our golden die algorithms from the past.

I think there's a variety of reasons, and at the end of the day, the customer just wants the best cost of ownership, most flexible system for the valuable fab space that they have. This system is designed for several generations ahead, and yeah, we're happy we won and look forward to continuing to win.

Edward Yang

That's very helpful color. For my follow-up, would just be on the 2027 outlook.

Sounds like you have a rich menu of growth opportunities. Obviously, a very favorable industry backdrop, but a lot of internal drivers, as well.

If you were to rank order the opportunities you're particularly excited about, whether it's Atlas G6, Dragonfly, 3Di, Iris, JetStep, X-ray, etc. Maybe give some color around how you feel about 2027 and your ability to outgrow WFE.

Thank you.

Michael Plisinski

You're asking me which of the children I love best. I think the highest growth and the highest contributions to growth or potential share gain opportunities will definitely come from the Dragonfly G5.

I think it's expanding into or has the potential to expand into nearly $1 billion in new markets. That's exciting.

The existing markets it's serving are also growing. I think there's a lot of opportunities for Dragonfly.

The Atlas G6 is making good progress in gate-all-around customers. That's going to continue to ramp, and the OCD continues to be a critical component for process control in the gate-all-around technologies, even as we look at integrating X-ray systems in order to extend the opportunities for OCD, and expand the opportunities for OCD.

These are complementary, not replacements. I think they work well together.

In addition, I think the surface charge metrology is another good growth area for us. We see more and more interest especially from packaging as chiplet architectures become more mainstream.

The concerns around charge metrology or residual charge having an impact on yield, a direct impact on yield for a package is high. The products that we're coming out with and opportunities for the SDI, I think are continuing to grow.

That's another exciting opportunity. Of course, right up with that is the panel-level market products we have with both the JetStep and the Firefly.

We talked about some growth there as well recently, and we see a meaningful shift now with the panel market starting to gain traction and people recognizing some of the benefits there. Then there's some more things, of course.

Edward Yang

Suffice to say you expect to outgrow WFE?

Michael Plisinski

Yes.

Edward Yang

Next year? Okay.

Michael Plisinski

We do expect to next year as well.

Edward Yang

Perfect. Thank you very much.

Operator

We'll take our next question from Matthew Prisco with Cantor.

Matthew Prisco

Thanks, guys, for taking the question. Just wanted to start on the advanced packaging market and the kind of improved outlook there.

Primary drivers within that, what got incrementally stronger over the last 90 days between maybe HBM, CoWoS, CoWoS-like, panel-level packaging, and what's included now in that number from a G5 perspective? Thanks.

Michael Plisinski

For all the growth we talked about, how much of it is G5, it's still relatively small. Call it less than 10%, maybe even 5%.

It's ramping, we

Matthew Prisco

How do you think about those other areas then?

Michael Plisinski

Pardon me?

Matthew Prisco

Then maybe how do you think about all those other areas playing and being contributors to growth? Oh,

Michael Plisinski

they're significant contributors to growth. The G3 demand is still going up.

The G5 is ramping every quarter. It's growing very dramatically.

Starting from zero, Q1 is going to be a handful of tools. Q2, Q3, it continues to nearly double each quarter throughout the year.

It's growing quite a bit. I think overall, yeah, you're looking at over 50% growth in advanced packaging.

If I think about 2.5D logic or HBM, they're very similar in growth outlooks for us, similar to what they were in '24 when everything was ramping. I think we talked about them split roughly equally.

Matthew Prisco

Gotcha. That's helpful.

Then maybe could you talk a little bit more about the Rigaku collaboration and how you think about revenues there ramping in the second half primarily, it seemed like, starting with software, and then how we should think about that combo optical X-ray tool, timing of that system and, potential magnitude of that opportunity over time?

Michael Plisinski

On the software piece, we'll provide some more guidance as we continue to gain experience working with Rigaku as they drive the sales. We're two separate companies now, our software attach rate to their CD X-ray tools it's depending on their CD X-ray tool pipeline.

We've looked. We think it's quite healthy.

We need more experience with how long it takes to close and based on what we've seen, I would say we expect that software revenue to grow throughout '26 and then grow even further in '27 based on the pipeline we've seen. We're now starting to leverage some of our contacts in the industry and with some of these customers looking for new opportunities now that we have a more solidified arrangement, and so that number could grow.

We'll provide more guidance as we continue to work together. The hybrid metrology solution, that's further out.

That is more working with customers, understanding their challenges, and then looking at ways to combine information to provide production-worthy systems N+2 kind of several generations out. OCD right now is going to cover through 1-nanometer-type processes.

There'll be some incremental sales we talked about. The hybrid metrology is going to be more on some of the new technologies coming out in a couple years.

That means we're starting now in R&D, working with our partners in the R&D space, and then look at timing for HVM, and that's where the real money will come in.

Brian Roberts

Matt, in its simplest form, as I mentioned in my remarks, if you think about just from an interest income or the forgone interest income and think about what it means for us over the next 12 months, we feel very confident that we will more than pick that back up through the combination of the licensing revenue that we've talked about as the primary kind of revenue stream plus then the dividend income that we'll see from Rigaku. Those two numbers together from an income perspective should offset what we're forgoing in interest.

Matthew Prisco

That's helpful.

Operator

We'll take our next question from Vedvati Shrotre with Evercore ISI.

Vedvati Shrotre

Hi. Thanks for taking my question.

My first one's on advanced packaging. You talked about two growth opportunities.

Additionally, like silicon photonics and panel-level packaging, can you help kind of size the revenue opportunity that could be here and when do you expect to start seeing volumes on this?

Michael Plisinski

We're already starting to see some volumes in silicon photonics. That from a size, I think you look at the end-market demand, and it's quite high.

You think about all the AI servers going in, and all this desire to reduce the power consumption of those servers provide additional speed between the memory and the logic as well. Two different areas silicon photonics are being used: co-packaged optics.

It can mean quite a bit of volume. The question is how quickly it gets cut in.

We've talked about several different customers that we've already been selected and gaining traction, gaining orders. We have a kind of a good visibility and pipeline into additional orders or additional opportunities through the next, say, 12 months.

I think from a sizing perspective, it's a little early to be too specific. I would definitely see this as one of our high-growth areas from a relatively low base, but very high growth based on end-market demand and need.

Vedvati Shrotre

How about panel-level packaging? Then I have a follow-up.

Michael Plisinski

Panel-level packaging, I don't think we've come off of the $200 million or so that we've said over the several years, and that includes the JetStep and the Firefly. I would say there's more of a bias as the industry starts to shift to this, or we see more manufacturers move to a panel packaging format, that number could go up quite meaningfully.

For now, that's sort of a range you can think about.

Vedvati Shrotre

Understood. For my second question, I kind of wanted to understand what your tool lead times are.

You talked about some of the headwinds like the DRAM cost. Are there any supply chain bottlenecks that are starting to creep up on the tools?

Michael Plisinski

I'm sure if you ask our COO, he'd say, "Yeah, plenty." In general, we're managing through them.

None of them are impacting our production and our commitments to customers. We're doing a great job managing through the issues that pop up.

This is one of the benefits of moving to the extended factories. We also, through that process, did some pruning of our supply chain tree.

As we looked at shifting and who could support our overseas factories, we made some changes to certain suppliers that didn't have the scale and capability to grow with us. I think right now, we're in relatively good shape.

Of course, lead times are extending out a little bit, but so far, no big issue, and we're able to meet customer demand.

Vedvati Shrotre

Understood. Thank you.

Operator

We'll take our next question from Charles Shi with Needham.

Charles Shi

Hey, good afternoon, Mike, Brian. Maybe the first question regarding the Rigaku collaboration and the expected licensing revenue.

I know you want to spend a few quarters to understand how to better forecast and maybe guide, and we also understand this is highly complementary to what you have on the optical side. Can you kind of talk to us, what's the expected licensing revenue?

What is the economics that looks like maybe on a per-tool basis, each tool Rigaku ship out? How much licensing revenue can you get?

At least give us some sense on the order of magnitude. Is it a few hundred K, a few millions?

What's the economics? Thanks.

Michael Plisinski

We're not going to break that down for anybody. Brian did a nice job highlighting the components.

If you look at potential interest income of the investment that we made, and then you subtract out roughly $7 million for dividends, then the residual is what we'd expect to see from license revenue and from profits from potential hybrid metrology sales. I think that gives you a rough idea.

Overall, that is not game-changing for Onto Innovation from a revenue perspective this year. The whole point is this was a strategic initiative that expands our opportunities significantly as we look out 3, 4, 5, 6 years ahead.

Charles Shi

Got it. Thanks, Mike.

Maybe asking you a longer-term question regarding your positioning for hybrid bonding-related inspection metrology opportunities. Definitely understood that you have a strong portfolio across different platforms: Dragonfly, maybe EchoScan, et cetera.

Rigaku probably is also working on some X-ray-based solutions there. How do you think about the positioning between your offering versus theirs, and especially for some of the applications, there seems to be some overlap.

For example, EchoScan versus some of the X-ray-based solutions they may be working on. How do you solve that overlap maybe you end up competing for some of the same opportunities and any color, any thoughts would be great.

Thanks.

Michael Plisinski

I think, Charles, you're very well informed. You picked about the only overlap that exists, and we don't know a lot about what that is about.

There is a potential overlap in packaging for X-ray inspection. That, I think between our EchoScan and that.

At the end of the day, optical systems should always be much faster. The EchoScan, if it reaches its full potential, should be much faster, and then it's going to be a benefit.

The X-ray benefit is going to be precision, and it's going to be penetration depth. In that case, there could be opportunities where If you understand inspection, which I know you do, one is the inspection tools, the other is the high-end review tool.

Optical inspection and SEM review, as an example. They can work together.

They can coexist. That's part of the reasons we like this expanded opportunity to expand the portfolio, and together, offer customers the best-of-breed technologies.

Right now, and that's about the only area. Otherwise, the films, the CD sacs versus optical CD, all of these are complementary.

As long as the OCD can measure, which so far, we've demonstrated we can push OCD technology beyond where most people thought possible, they'll go with OCD. There are definitely gaps that we're starting to see, especially as 3D becomes more of a dominant part of the customers' process roadmaps, where penetration depth is critical.

It's going to provide some insight into the OCD modeling engines that'll make OCD more valuable or, let's say, extend OCD further down the line. Get the speed of OCD with the precision and penetration depth of X-ray.

Charles Shi

Got it. Thanks.

That's very clear. Thank you.

Operator

As a reminder, if you would like to ask a question, you may press *1 on your telephone keypad now. We'll take our next question from Brian Chin with Stifel.

Brian Chin

Hi there. Good evening.

Thanks for letting us ask a few questions. Mike, referencing the 2.5D logic win, just to clarify, are you baking in a relatively modest contribution from Gen 5 sales to this customer in the second half?

Could that be conservative? Also, when you think about that qualification improving and strengthening your competitiveness for the variety of applications that that customer has, can you hazard a guess where your market share at that customer might shake out moving forward?

Michael Plisinski

I don't want to say exactly what could happen. For sure, we've got new opportunities within the account that with the previous system that we couldn't serve.

We definitely see that. Could our forecast be conservative?

Sure, it could be. Could there be upside to the second half?

Sure, could be. We gave the guidance now, and next quarter, we'll provide this additional guidance and see how things shake out.

I don't think it's all tied to this customer. We mentioned 10 additional customers looking at the G5 for applications, about 15, I believe I said, over 15 applications, many of which we wouldn't have been able to serve in the past.

The opportunity to expand our overall SAM is also creating excitement and growth and upside for maybe second half, but definitely into 2027.

Brian Chin

Kind of a mini question before I ask my follow-up. Relative to last year or the year before, there does seem to be a lot more breadth of potential customers, as opposed to the recent years where it was pretty concentrated.

Michael Plisinski

For sure. Yeah.

We see this advanced packaging being migrated as customers try and focus in on their high-value-add process steps, and they outsource to others some of the other process steps. We're seeing opportunities to Well, we're not seeing the opportunity.

We are growing our position in those outsourced partners. We're definitely seeing a proliferation naturally through our customer base as well.

Brian Chin

Thank you. Then for the follow-up, is the Atlas TSV application win you referenced an example of the synergy between the two companies' optical and X-ray technologies?

Also, the Rigaku relationship sounds undoubtedly like it's focused on the semiconductor engagement. Given that a large portion of Rigaku's business is also outside of semi, are there any opportunities or plans to engage in markets beyond semi?

Michael Plisinski

Specific to Rigaku, we're focusing on semi, and they also see semi as one of their key growth pillars. I think that's a great synergy and a great reason why working together, we can provide the strengths not just of technologies, but also of our footprint and infrastructures.

I think that's going to be our focus, at least for the foreseeable future, and where the biggest benefits will be realized. First question,

Brian Roberts

TSV?

Michael Plisinski

No, that was homegrown. That was leveraging the capabilities of our Atlas to do some very specific metrology that was previously done by a different OCD supplier.

Brian Chin

Great. Thank you.
