Ilan Daskal: Thank you, Vibhuti. Good afternoon, everyone. Now I would like to review the results of the third quarter of fiscal year 2026. Net revenue for the quarter was $406.8 million, which is above the high end of our guidance range of $386 million and $400 million. Revenue was up 10.2% sequentially and on a year-over-year basis was up 42.8%. Operating margin for the third fiscal quarter was 21%, above the high end of our guidance range of 19.2% and 20.2%. Operating margin increased 170 basis points from the prior quarter and on a year-over-year basis was up 430 basis points. EPS at $0.27 was also above the high end of our guidance range of $0.22 to $0.24 and was up $0.05 sequentially. On a year-over-year basis, EPS was up $0.12.

Moving on to our Q3 results by business segment. NSE revenue for the third fiscal quarter came in at $321.5 million, which is above the high end of our guidance range of $304 million and $316 million. Revenue from Spirent product lines was $54.2 million, which was in line with our expectations and included a few opportunities that were pushed out from the prior quarter. On a year-over-year basis, NSE revenue was up 54.4% primarily driven by the acquisition of Spirent product lines. We also saw strong demand for our level production and field products driven by the data center ecosystem as well as for our aerospace and defense products. NSC gross margin for the quarter was 65.3%, which is 220 basis points higher on a year-over-year basis and was primarily driven by higher volume and favorable product mix.

NSE’s operating margin for the quarter was 17.2%, an increase of 680 basis points on a year-over-year basis. NSE’s operating margin was also above the high end of our guidance range of 15% to 16% as a result of a higher fall-through. OSP revenue for the third fiscal quarter came in at $85.3 million, also above our guidance range of $82 million to $84 million. On a year-over-year basis, OSP revenue was up 11.4%, primarily driven by strong demand for 3D sensing and anticounterfeiting and other products. OSP gross margin was 50.3%, down 130 basis points on a year-over-year basis, and it was mainly due to unfavorable product mix. OSP’s operating margin was 35.3%, an increase of 140 basis points on a year-over-year basis. OSP’s operating margin was in line with our guidance range of 34.8% to 35.8%.

Moving on to the balance sheet and cash flow. Total cash and short-term investments at the end of Q3 were $508 million compared to $772.1 million in the second quarter of fiscal 2026. Cash flow from operating activities for the quarter was a use of $26.3 million versus $7.8 million that we generated in the same period last year. The cash flow was mainly impacted by the earn-out payments to Inertial Labs, timing of working capital and employee variable costs. CapEx for the quarter was $5.9 million versus $6.8 million in the same period last year. During the quarter, we successfully paid $49 million in cash for the remaining principal of the convertible notes due in March 2026, and we issued about 1.8 million shares for the conversion premium above par.

We also prepaid during the quarter, $150 million of the Term Loan B. We currently have $450 million remaining for that loan. The prepayment is in line with our capital allocation priorities. During the quarter, we did not purchase any shares of our stock as we prioritize our capital allocation towards debt management. The fully diluted share count for the quarter was 249.5 million shares, up from 226.9 million shares in the prior year and versus 245 million shares in our guidance for the third fiscal quarter. Moving on to our guidance for the fourth quarter of fiscal 2026. We expect the fourth fiscal quarter revenue for Viavi to be up sequentially, driven by continued strength in many of our end markets across NSC and OSP. For NSC, we expect quarter-over-quarter revenue to be higher as a result of continued strong demand for our 11 production and field products driven by the data center ecosystem as well as for our aerospace and defense products.

For OSP, we expect quarter-over-quarter revenue to be higher, driven by strength across all of the product lines. For the fourth fiscal quarter of 2026, we expect Viavi revenue in the range of $427 million and $437 million. We expect NSE revenue between $340 million and $348 million. OSP revenue is expected to be in the range of $87 million and $89 million. Operating margin for Viavi is expected to be 22.7%, plus or minus 50 basis points. NSE operating margin is expected to be 18.7%, plus or minus 50 basis points. OSP operating margin is expected to be 38.4% plus or minus 40 basis points. And EPS is expected to be between $0.29 and $0.31. Our tax expenses for the fourth quarter is expected to be about $10 million, plus or minus $500,000 as a result of jurisdictional mix.

We expect other income and expense to reflect a net expense of approximately $12 million, and the share count is expected to be around 256 million shares. With that, I will turn the call over to Oleg. Oleg?

Oleg Khaykin: Thank you, Ilan. The results of the third quarter of fiscal ’26 exceeded our expectations and came in above the high end of our guidance. The strong year-on-year and quarter-on-quarter performance was driven by strong growth in many of our end markets. NSE revenue in Q3 grew approximately 54% year-over-year, primarily driven by strong demand from the data center ecosystem and aerospace and defense customers. The data center ecosystem, which includes high-performance semis, optical modules, NAMs, and the hyperscalers drove strong demand for 11 production and field instruments in support of AI data center build-out. We are seeing strong demand across all data center segments. Scale up, scale out and scale across.

Acceleration of industry investment in ever greater communication speeds and chip-to-chip interconnect technologies are the principal drivers of strong demand for our optical transport silicon photonics and communication protocol and high-speed Ethernet test equipment. The Q3 growth was also helped by a recently acquired Spirent high-speed Ethernet product lines, which gave us access to a large installed base of enterprise customers. HSE performance came in line with our expectations. Given strong and growing customer demand, we expect the data center ecosystem revenue momentum to continue through the calendar 2026. Our Aerospace and Defense business also showed another strong quarter-on-quarter growth, driven by continued growth demand for our positioning, navigation and timing products.

We expect this trend to continue through the calendar year. The service provider business, which includes field instruments, wireless and service enablement was in line with seasonality. As you may recall, the service provider business is seasonally weaker during the March and September quarters and seasonally stronger during the June and December quarters. Some notable on the service provider dynamics during the March quarter included early orders from cable operators relating to the new DAA architecture and continued weak but stable demand for wireless test products. We do not expect to recovering growth in the near term for wireless business. Now turning to OSP. OSP saw strong year-on-year growth, driven by strong demand for 3D sensing and anticounterfeiting products.

Looking ahead to Q4, we expect NSE revenue to be up quarter-on-quarter, driven by continued strong and growing demand from the data center and aerospace and defense customers and seasonally stronger service provider spend. We expect OSP to be up also quarter-on-quarter, driven by strength across all product lines. In conclusion, we expect our data center and aerospace and defense end markets to be strong drivers for the foreseeable future. I would like to thank the Viavi team for its continued strong innovation and execution and thank our customers and shareholders for their continued support. With that, I will now turn it back over to the operator for Q&A.

Operator: [Operator Instructions]. Your first question comes from the line of Ruben Roy from Stifel. Your line is now open.

Ruben Roy: Great. Thank you. Hi, Oleg and Ilan. Congrats on the momentum here in the business. I guess to start, Oleg, maybe we could just drill into the data center momentum. And if you think about sort of the first half of the year and what you’re seeing here with the beat here in the March quarter and the guidance for June. Can you detail out sort of a little more detail around the drivers by production field, and maybe just kind of what you’re seeing in terms of visibility from your customers? Obviously, a lot going on with AI infrastructure networks and that type of thing. But just trying to get to a little more detail around lab production at field and how you see that sort of trending from here as you look ahead.

Oleg Khaykin: Sure. Well, I mean, the — on the lab side, it’s your classical optical transport and PCIe express test products. So as you develop all these new AI chips for inference or the training, it requires, as you can imagine, very high speeds for all the ports and the overall traffic. So I mean, everybody who is working on any kind of product out there that’s going to go into these next-generation systems, be it for AI training or inference is buying our optical transport and our protocol test solutions. So that’s primarily lab, but also exactly same equipment is being bought by NAMs or building optical switches and all the other gear that goes into the systems. And that’s kind of on the lab side. On the production, we are seeing a lot of momentum on this whole co-packaged uptick area, and that plays extremely well to the traditional Viavi strength with the old JDS Uniphase products that go into the production line where you’re measuring spectral performance, the optical performance of all the various optics, but it’s also — we are selling now a lot of that equipment to the semiconductor vendors as they develop their integrated packaged optic solutions.

So I mean, it’s pretty much everything we do in that area relating to the advanced silicon for both training and inference applications and all the optical gear that goes into these data centers is playing perfectly aligned to our portfolio. Now on the field instrumentation side, as all these data centers come up, they are putting a lot of investment into ensuring peak performance. And I tell you, I mean, I’ve never seen so much demand for our fiber monitoring solutions. I mean, I’d say these data centers buying more equipment than regular service providers for the whole big network. So that is obviously driving the whole field instrument side of the business. I mean, it’s now approaching cost to, let’s say, 40%, 45% — pretty soon probably maybe 50% of the field instruments is actually driven by the data center.

So in that respect, it’s a very good alignment between what the market needs and what we actually have.

Ruben Roy: That’s great detail. I guess for a follow-up on that. You had started to see some hyperscaler activity around 800 gig, I would assume last year, some of these things that you’re talking about in answer to the question and on the call today, things like 1.60 co-packaged optics. They’re actually just starting, it seems like. Is that the right way to think about it? And I guess the question…

Oleg Khaykin: Go ahead.

Ruben Roy: I was just going to ask the question, it would be sort of in terms of your mix here, is it — I would assume it’s still more weighted towards some of the older generation technology? Or is that the wrong way to think about it? And kind of how do you think 1.60 and some of these new products layer in, I guess, is the question.

Oleg Khaykin: Yes, it’s all. I mean the 800 is still very much a high volume driver. But a lot of the new development is using our 1.6. By the way, we released 1.6, 1.5 years ago. So you just see — actually, ironically, it was initially the NAMs, the optical equipment vendors who deployed it first in development. And now it’s spreading to the semis and the whole co-packaged optics. So yes, I mean, 1.6 is ramping in a lab. And we’re also having some of the early production products to the module vendors. But there’s no like one way or the other, it’s actually both of these are — one is ramping into volume, the other one continues to be strong in the volume.

Operator: Your next question comes from the line of Mehdi Hosseini from SIG.

Mehdi Hosseini: Yes. Oleg, congrats on execution. I want to get a bigger picture and looking more longer term I see your midpoint of your June quarter guide implying annualized earnings of $1.20 which is much higher than the prior peak from FY ’22. And with that context, how should we think about company’s earning power over the next 1 or 2 years. And I’m not asking for a guide, I just want to get a better picture of how these — the new vector the demand factors that are materializing are going to enable you longer-term earning power. And I have a follow-up.

Oleg Khaykin: No, it’s a great question. So I think clearly, I would say our NSE business is now getting very close to 20% operating profit. It’s all volume driven. So for every incremental dollar in NSE, I mean, you’re getting about what to $0.45 dropping to bottom line. Ilan can give you a lot more detail on that. So clearly, that’s driving up the operating margin. Our OSP has always had pretty high operating margin, but also with the higher revenue, and that it’s now going from like was in a mid-60s to 70s. Now it’s moving to high 80s to maybe low 90, while that gets you a couple of percentage points higher gross margin, which then obviously drops right down to the a couple of percentage points higher operating margin. So already at the blended average, we are, like, what, 23%, 24%.

And as NC keeps getting stronger that will keep moving into the mid-20s and maybe higher. So in that respect, there is a tremendous operating leverage that comes with volume. And also, we’ve been able to weather pretty well any kind of the price increases due to components and component shortages, and as we probably will try to pass some of that increases to our customers, that will be an additional mitigation of the cost, which will probably give us a little bit more expansion on the gross margin. So clearly, a combination of keeping up with the price increases and passing around, maintaining healthy gross margins volume growing, driving significant operating leverage. And fundamentally, it scales very nicely from here this point on. I mean as our fixed costs fully covered, every incremental dollar is what, about 40%, 45%.

Ilan Daskal: So for modeling, Mehdi. So on the NSE side, it’s around today, the 40% level. And obviously, the top line, we assume will continue to drive as it continues to grow. So when you think about the operating leverage and the operating income, for NSE and the company? I mean…

Oleg Khaykin: And I’ll say last but not the least, we’ve talked a lot about our NOLs. Well, guess what? Now that we are generating a lot of profit and a lot of it falls in the U.S. jurisdiction because of where our IP and R&D is, I mean, all that incremental profit comes in at virtually 0 tax in the North America.

Ilan Daskal: This quarter, for example, the effective tax rate is about 12%. So definitely another benefit there.

Oleg Khaykin: I mean the only level — you have is with the converts you get a little bit dilution as your price stock price goes up. So you’ve got to factor a bit higher share count in your calculations.

Mehdi Hosseini: Okay. And my second question or follow-up. I want to come back to a scaling right now against midpoint of the June quarter implies about a 25% growth from the prior peak from mid-’22. And back then, 5G wireless was a big factor. I’m on your assumption that wireline, especially as we roll out 1.6 that subsequent to that 3.2% offers the bigger TAM. And given that setup, yes, you have been able to scale revenue through acquisition, organic growth. But where do we go from here? Is there any way you can help me understand the growth the growth from here, especially cannibalized by 1.6 and 3.2.

Oleg Khaykin: Well, so I think the intensity of our equipment increases as you go into higher speeds for both not only the networking speed or bandwidth, but also with a chip-to-chip interconnect. And then on top of it, you throw in things like co-package optics or near package optics and all that. So actually, you’re not only growing with the market, you are also having a broadening of areas where our equipment is being bought. I mean, for example, when you start making manufacturing multi-mode and hollow core fiber, you now — before we never really sold into the manufacturing lines. Now the level of complexity in this product requires our instruments so we are now seeing opportunities emerging where we will be selling into the production environment on things like fiber manufacturing, right?

Things like people making co-packaged optics or integrated optics while now you are selling optical equipment into the lab that before you only used for maybe fiber optic modules. Now they need to characterize and design these optical components and then all these optical components need to be tested in like multiple insertions because the yield is so critical when you build this whole module I mean if you have one device is bad, you throw away the entire once it’s completely sealed, you can’t rework it. So you have to test every component that goes into the module, then you test it again once you mount it. And only at the end, you put an ASIC on to the module. So in that respect, it drives a tremendous amount of test requirements in the manufacturing process.

Mehdi Hosseini: I completely understand. I think your booth at OFC in March was illustrated at this increased test insertion points. But I guess back to my question, could this opportunities help you with the $500 million of the quarterly revenue? I’m not asking for a specific timing, but is the $500 million of quarter revenue a realistic target?

Oleg Khaykin: I think it’s entirely realistic. I mean, look, I think this quarter, we are at midpoint is well around 232. I mean, so it’s moving in that direction. Remember, it’s not only — it’s, I’d say, it’s early on. We’re seeing a lot of early demand in this truly as a lot of the next-generation optical equipment and components come into being. I mean you look at some of these new high-power Ethernet, which is a day embedding like optical photonic integrated circuits into substrates and OLED. So it’s — the scope of the market is expanding tremendously. And let’s not forget our Aerospace and Defense business. It’s also growing very nicely. So we don’t talk much about it, but that business is like also driving the wave. And last but not the least, wireless will not be down forever.

Eventually, we do need to consume all the data and all the through our wireless devices. So I think eventually, either the service providers or some other money will come in to take the wireless infrastructure and make it AI rent which will rebound the spend in that market. And today, our wireless business is down about 45%, depending on the quarter. And that alone could drive $20 million to $30 million additional quarterly revenue.

Ilan Daskal: And maybe, I assume just to make sure that we are levering kind of the expectations here. I assume first you referred on the $500 million to the NSCP [indiscernible] Viavi but it’s also not…

Oleg Khaykin: I think he;s talking about [indiscernible] of Viavi.

Ilan Daskal: So that’s what I wasn’t sure. But in any case, this is not necessarily kind of immediate next fiscal year. This is over kind of the next kind of upcycle.

Operator: Your next question comes from the line of Ryan Koontz from Needham.

Ryan Koontz: Terrific results, guys, just excellent. Maybe just a quick clarification on the data center customer mix there. It sounds pretty broad and diversified. But as you think about the different types, the semis, the optical, the NEMs, the operators, can you give us maybe an order of kind of which one of those customer segments is driving the are the biggest within the data center mix today?

Oleg Khaykin: It’s fairly well — it varies quarter-by-quarter. I mean I mean, let’s first way, the actual data centers are buying quite a bit. I mean, so it’s — if you only just take the one single segment, I would say the hyperscalers would be biggest bucket because they not only buy equipment for data centers, but they also run their own R&D, developing their own processors and modules and the ops right. And within the hyperscalers, I’d say there is the ones who are much more into doing their own staff are actually much bigger and some that are not so big. But it’s percolating across, right? And the next big bucket would be the modules — module makers and the system makers, right? People making optical modules and optical systems. And I would say the next bucket is the silicon vendors. And I mean I mean, I haven’t really looked at it, but it’s a fairly even balanced distribution.

Ryan Koontz: That’s great color. And maybe switching gears to Spirent. Obviously, they’re a big part of your success here in data center as you build that momentum. Can you maybe talk about the synergies you’re seeing with that business as it relates to both the product side of the house as well as the sales side?

Oleg Khaykin: I would say the — I mean, clearly, they come with a pretty big established customer base. I would say we are really upgrading the performance — hardware performance of their products, which makes them much more competitive. But they have a very good established reputation and the, I would call it, application hardened software for all kinds of Ethernet traffic. So, in a way, it’s a good combination, accelerating our hardware development to the ever higher speeds and bringing their software and combining it together. I’d say the first truly integrated product that we’re going to have between them and [indiscernible] 3.2 terabits. But we are doing very well already leveraging our 800-gig position with their 800-gig Ethernet test and obviously expanding it to our customers who they did not have, but also getting access into their customers, which drives broader discussion and more strategic discussion around not only high-speed Ethernet, but all the other products that we bring into the mix.

Ryan Koontz: That’s great. Sounds like the cross-selling is already beginning there. And maybe just some of the emerging — if I get one last one in here around emerging product areas, obviously, defense is one. How would you characterize where you are in winning share for this P&T with the growth in all the drones? And would you touch on maybe what you’re doing in wireless in the satellite arena you see that as an emerging opportunity for LEOs.

Oleg Khaykin: So the positioning, navigation, timing, actually, a lot of the revenue that we’re seeing today and driving today, most of it was actually designs that were won before we acquired them. But we’re now starting to see even things coming ramping up ever since we acquired it. But if I look at the funnel of wins in the last, let’s say, 12 months, as these things kick in, that momentum will continue to drive that business. So it’s all goodness and it’s clearly drones is a big one, but pretty much anything autonomous, I mean, whether it’s air, land, sea or undersea vehicles, is — creates a great pool. And we are now winning some of the U.S. Tier 1s. I mean, traditionally, they were very strong with Tier 2s and a lot of international.

And I would say in the past, year, we have really — as we brought in a lot of the kind of discipline around the implementing ITAR and various secure access systems we are now being considered by U.S. Tier 1 players, and we are starting to play in much bigger leagues in that respect. So that was the aerospace defense. Your satellite question on wireless. Well, as I tell my wireless team, when the market is awful, focused on the next generation, and it’s 6G, it’s NTN and all these kind of applications. And we are very heavily involved with kind of the 5G plus 6G. And a lot of it is really focusing on the two types of communication, the AI RAN, which is basically running AI traffic through the advanced a wireless network and the ground to satellite communication.

So this is what a lot of our advanced wireless applications are focused on today.

Operator: Your next question comes from the line of Andrew Spinola with UPS.

Andrew Spinola: I wanted to ask on the component shortages and some of the supply constraints. I’m just wondering if during the quarter, you were able to meet all of the supply or all of the demand rather or the supply constraints limited to you? And as a part — sort of like an addendum to that question, we’re starting to see a lot of long-term supply agreements in other areas in this industry to meet the hyperscaler demand and sort of increases in visibility a couple of years out. So I’m wondering what your visibility is like have you started to enter into any long-term supply agreements with some of your bigger customers? What’s evolving on that side?

Oleg Khaykin: Thank you, Andrew. Well, I mean, I don’t think — we don’t have the volumes to enter into a long-term supply agreement. And remember, test and measurement, usually, it’s you’re leading a lot of the value market. So you have to buy the latest and greatest. So what’s more important for you is not necessarily supply agreement, but the early access. It means you’re accessing alpha silicon or beta silicon well before it’s released. So you can develop the products there are available even before the qualified silicon is released to the market. So that is where we focus on. In terms of the availability, in Test and Measurement, you generally pay the highest ASP of their price distribution. So it’s never a problem to get it.

You just got to make sure you give them — you get enough notice. So when you — I would say, if we say supply shortage would not be because we would not give the material. We just didn’t get — we get an upside order with too little lead time to get it in. But generally, you pay more money, you always get the product. So — and the nice part about being a bleeding edge of the test and measurement, people need the product that works and pricing is secondary in that respect. Now as you get into more mature products like field instruments, handhelds, yes, their cost is very important. And there, we generally maintain inventory. I mean we got a lot of headache from my CFO and our Audit Committee a few quarters back because we went in and put some product on the shelf because we anticipated the shortage coming in.

And today, we look pretty smart as a result of it and nobody is complaining. So in the end, I mean, you got to manage your supply chain. And last thing you want to do is be pennywise and found foolish. And I mean if you don’t pay, then don’t complain, nobody is going to give you any availability. So far, we have — I mean clearly, there is supply shortage, especially memories. I mean, listen, I think memory is going to be a deficit for the — till 2030 according to some of the studies I’ve seen. But given our volume requirements, it’s not such a big deal. I think having a product available ahead of everybody else and having early access is probably what’s more important.

Ilan Daskal: And I can add to that also, if you look at our balance sheet for March, you will see on the inventory level, it’s up single-digit million. The majority of it was to secure some additional components for the [indiscernible].

Oleg Khaykin: And I mean — and we look 2, 3, 4 quarters out, and we’ll make some bets because it’s not the issue if we don’t get the product. It’s really the lead time. and making sure we give adequate notice to the vendors.

Andrew Spinola: Appreciate that color. One follow-up I wanted to ask. You talked about incremental margins earlier on the call of 40% to 45%. I think that makes a lot of sense. It looks like that’s what’s in your numbers. And for Q4 in your guide, and I’m trying to think about how to think about fiscal ’27. And so my assumption is that you’ve got the 40% to 45% incremental on the core business as you scale. But what I’m really asking about is you announced last quarter, I think it was about $30 million of restructuring. I think you acknowledge some of that will probably get reinvested. But I’m wondering, at this point, if you could give us any color on maybe how much of that is going to drop to the bottom line? How much of that is going to be reinvested. And frankly, my assumption would be a good chunk of that is going to hit the bottom line. So maybe incrementals in fiscal ’27 are closer to 50%. So I wonder if you could comment on that?

Oleg Khaykin: Well, maybe I’ll start and Ilan will give you details. So we’re going to implement most of it by the end of our fiscal year, so the June quarter. And there’s some remainder that probably will go through the end of the calendar year. And I think, Ilan, what is it roughly 1/3 of it gets reinvested.

Ilan Daskal: Yes. And Andrew, the 40% fall-through that we see right now, we probably — and there is a good reason to assume that it can go higher Specifically, if you think about the second half of the fiscal year next year, meaning 27, there is still the seasonality that Oleg mentioned in the prepared remarks. So if you think about the September quarter, usually it’s a down quarter for us, et cetera. And we need all the restructuring to materialize, and that will take also until the end of the calendar year, this calendar year. So the increase in the fall-through from the 40% level it’s fair to assume that with the top line kind of growth will be more visible in the second half of the fiscal year of next fiscal year, meaning it’s the first half of the calendar year of ’27.

Oleg Khaykin: So one thing I just want to clarify. When he launches September quarter is a seasonally down quarter for us for service provider segment, that’s what it is. So if you think about it, in the old days before we had this whole data center and aerospace and defense. If you look at the old Viavi, it’s like March and September quarter would be the down quarters because that’s the type of spending that of service providers. By the way, that pattern is still there, except now it’s on a much smaller scale. But because of the Aerospace and Defense and our data center business is growing so strongly. It’s more than offset but you still have that underneath it, you have that up and down. So you would see like a much bigger jump between March and June quarter because you have a tailwind from service providers.

Conversely, you’ll have a smaller increase in the September quarter because you have a headwind from the service providers. Then in December, you’ll have a tailwind again. So I mean, this thing is still there. It’s just becoming more and more muted from impact on the overall Viavi.

Ilan Daskal: And on a quarter-on-quarter kind of trajectory overall, December is stronger versus September and September is still more muted relative to the June number.

Oleg Khaykin: That’s right.

Operator: Your next question comes from the line of Michael Genovese from Rosenblatt Securities.

Michael Genovese: Thanks. Exciting times, guys. Congratulations for being right in the middle of it.Oleg, I keep hearing now as we go to silicon, more silicon photonics and more co-packaged optics that the bottlenecks to the whole thing are moving to the packaging from the foundry players and to the test and measurement for the electronics, the optics, the engines and the ASICs. It seems like there’s so much testing to be done with co-packaged optics. So my first question is, do you agree that testing is a bottleneck? And if so, how will you address that over time to take advantage of that?

Oleg Khaykin: I’ll say, Amen, Brother, you’re absolutely right. So I mean, the whole test packaging used to be kind of a back-end afterthought. It is now the system. It’s now a strategic asset. So you look at companies like, well, I don’t want to name names, but all the leading semiconductor companies, the packaging expertise package is now the system. And you’re looking at integrating glass substrates. You’re looking putting photonic integrated circuits next to the electronic integrating circuits embedded into this whole coat chip on wafer on substrate, right? You’re building this really complex thing. And then if you look at — you’re putting now all these copackaged optics on a periphery of the chip, this thing is starting to look more like a brick and some of them weigh — I mean we’re talking about the chemos of weight, right?

So to me, that’s like music to my ears because as you probably know, I started in the [indiscernible] I ran Encore. So it’s like all the [indiscernible] field, you get no respect. Well, now the respect is like hugely and I mean, we are seeing now our technologies and our capabilities are being dragged into the straight into this whole value chain of testing from the individual optical components to wafer level packaging to the heterogeneous integration packaging all the way down to being integrated into major test platforms. And that’s like a whole new business that we did not even have. And then last but not the least, this whole rack-mounted systems that are being built as custom test by leading players. We’re supplying a lot of the guts and a lot of hardware that goes into those systems.

So, as I was saying, I think is like from the old JDS Uniphase date, we still have all these products, and now there’s a whole new life being injected into those products. And that’s something we didn’t even think about, I would say, 3 quarters ago.

Michael Genovese: Great. And then just as a follow-up, just with newer things like OCS, where I think you’re probably going to have very high market share for testing. And then for co-package optics, I mean are these in the numbers at all yet? Or is this is all in the future, I assume. And I guess maybe my question would be how do you define the foreseeable future when you’re saying that you feel great about the foreseeable future. Like how far out is that?

Oleg Khaykin: I would say it’s — in the current numbers, it’s kind of the early sales. But I’d say foreseeable future, you probably you’re talking 2 to 3 quarters when it starts ramping up. The future is not that far off. [indiscernible] selling right now is the early inning.

Michael Genovese: Right. Just to clarify the foreseeable future question. I mean, in the press release, you said something like we feel great about growth into the foreseeable future. So is that multiple years that we’re talking about?

Oleg Khaykin: No, no, no. I mean generally, we, as a practice, don’t want to go beyond end of the calendar year. So when I say foreseeable future like the next 3 quarters.

Operator: Your next question comes from the line of Tim Savageaux from Northland Capital Markets.

Timothy Savageaux: Congrats on some pretty spectacular results. It’s pretty simple question to start with. Well actually a confirmation and a question and maybe I’ll get a little more complex on there. So Spirent was 54.2% in the quarter. Is that right?

Ilan Daskal: That’s correct.

Timothy Savageaux: Okay. So I guess the simple question is, what do you expect for next quarter for Spirent?

Ilan Daskal: So Spirent benefited from a few orders that we mentioned already in the last quarter that got pushed out to this quarter. So this quarter, that’s the reason that it’s a little bit stronger than seasonality, we still expect on an annual basis, calendar annual basis, a similar run rate of around about the $200 million that we said with a split of around 45%, 55%. And — so that takes you to normalize everything still back to just shy of the $50 million, maybe $48 million for the June quarter.

Timothy Savageaux: Okay. Well, that’s a good answer because that speaks to higher levels of organic growth in your NSE business? Would I see approaching 40% here in Q4. The way I’m dicing things up here and over 30% for the year. So I guess I’ll try to tie the last question to this one and say when we see this type of environment for the foreseeable future, do you think you can see those type of organic growth rates, 30%, 40% for, call it, organic NSE continue over the next couple, 3 quarters.

Oleg Khaykin: Well, I mean one thing about percentages, it’s very hard to maintain same percentage. I mean because 30% on one number is much smaller than 30% on a much bigger number. But I think if you look at that growth in the absolute dollars, I mean that’s what we’re try to maintain.

Ilan Daskal: And Oleg just mentioned earlier, the service providers, which is part of the core NSE. And so if you think again, the seasonality of September, traditionally does not enjoy the same growth rate if you bundle everything together. So I’m not sure that our assumption is exactly, I mean, right? I mean it’s…

Oleg Khaykin: I think he’s talking about year-on-year. Year-on-year, when you have — when you needed quarter — same quarter, same dynamics, Yes, I wouldn’t say — I don’t think you could say like a 40%, but I think still a high number should be realistic because 40% on $400 million is one number. 40% on $200 million is a very different number, right?

Timothy Savageaux: No, I got it. Although I’d say consensus probably has you at high single digits right now given what you reported. So I could probably do a little bit better than that. [indiscernible] more for the full year of ’27. I’m just making serious comments. I’m not asking you to guide anything. You’ve been very helpful in giving the breakdown at least some I’ll ask for either 1 of 2 ways, which is kind of the data center, defense and service provider breakdown, if we can get an update there and/or growth rates in those categories estimated for what you saw here in fiscal Q3?

Oleg Khaykin: Well, I’d tell you, if everybody spends what they claim they’re going to spend, I mean, we still got a lot of growth to go on, right? So I mean, if you take those assumptions, I think we’re — I mean, the momentum, I’d say, we’re still in the fairly early segment of the ramp.

Timothy Savageaux: Message received there. Would you say data center, and again, this kind of with and without Spirent confuses thing. I assume with data centers saw solidly more than 50% of NSE revenue — but what I was looking for is, however you want to break it down, I think you’d said 45, 15. 40 before.

Oleg Khaykin: Yes. I think right now, the data center is — I mean, the exit velocity this year is inching to the high 40s. The service providers are inching towards mid-30s and Aerospace and Defense is a little over 15%. So I wouldn’t be surprised if data center in a not distant future, gets up to about 50% of our NSE revenue.

Operator: Your next and final question comes from the line of Andrew Spinola with a follow-up from UPS. Andrew, your line is now open.

Timothy Savageaux: I just wanted to ask a higher-level question about your drone business, your module business from inertial how is that business performing? Obviously, there’s a lot of demand and new programs in that space. And I’m just wondering what you’re seeing in terms of opportunities. How is that business positioned? Do you have all of the approvals and the ability to sell into all of the customers? How should we think about that opportunity over the medium term?

Oleg Khaykin: It’s a good question, Andrew. I mean so you can judge from it, the mere fact, Ilan said that we just paid out. If you look at our balance sheet, we paid out a pretty big earnout, means these guys have exceeded every forecast that they’ve given us. And as I tell you, in my career, I’ve made about close to 40 acquisitions. There’s been only two of them have exceeded their first year forecast. Okay. This is the only one at Viavi. I mean that business is doing extremely well. And they make products anything from the basic sensors that go into the inertial navigation system, to fully blown inertial navigation system that does a sensor fusion of GNSS the location, the ground speed, the LiDAR and all these other things.

So — and we are engaged with pretty much every drone munitions subsystem vendor of interest out there, both in U.S. as well as in the rest of the world. Now clearly, there’s a clear guidelines what constitutes control versus not controlled. When you [indiscernible] sensor, and it’s within a certain level of accuracy that for that you need a export approval. If you are making a product that’s more commercial, let’s say, you’re doing a surveillance drone or agricultural drone or something for mining industry. Those things are deemed to be commercial. So we have a very clear boundaries and how we define the products, how we grade them and obviously, how we price them. So all these things are some products so you can only export through the U.S. government export license others, you can just sell as a commercial product.

Andrew Spinola: And just one follow-up on that. It sounds like there’s particularly strong growth and demand for lower-cost drones. And I’m just wondering without knowing that market all that well. Would the inertial modules or some of those gyroscopes or sensors that inertial sells, would they be applicable for the lower-end drones for that opportunity?

Oleg Khaykin: When you [indiscernible] drones, if you’re talking something like $3,000 then no, if you’re talking something like $30,000, then yes.

Operator: There are no further questions at this time. I will now turn the call back to Vibhuti Nayar for closing remarks.
