Lumentum is at the forefront of the cloud and AI revolution, which is driving rapid growth in the advanced Photonics markets we serve. As AI becomes central to our customers' business strategies, the demand for optical hardware and bandwidth is growing dramatically. Our innovation is driving the next generation of AI infrastructure with technologies such as 200 Gb EMLs, 1.6 Tb transceivers, optical circuit switches, and ultra-high-power lasers with co-packaged optics, all of which are essential for building scalable, energy-efficient systems. Our years of optical engineering leadership provide us with a significant competitive advantage as AI architectures evolve. These new technologies are projected to become multi-billion dollar markets within five years. With a uniquely differentiated portfolio, Lumentum is positioned to capture significant value from this inflection, driving strong revenue growth, expanding margins, increasing profitability, all of which are elements of the long-term financial model we laid out in April. Cloud revenue is growing well over 20% annually. Company gross margins are set to surpass 40%. Through a combination of high-value products and disciplined cost management, we are targeting operating margins above 20%. The slope of our cloud-facing revenue is increasing. We now expect to surpass $600 million in quarterly revenue by the June 2026 quarter or earlier. Let's turn to our fourth quarter results. In early June, we raised our fourth quarter revenue and EPS outlook. Our cloud and networking performance drove Q4 revenue above even the high end of our revised expectations. Fourth quarter revenue from our cloud and networking segment increased 16% sequentially and 67% year- over- year, led by exceptional demand from hyperscale cloud customers. The outperformance was largely driven by our cloud-facing components and transceiver product lines. In components, we achieved an all-time high in EML shipments, nearly doubling the revenue compared to our June quarter 2024 baseline. Our wafer fab expansion is progressing on schedule, enabling us to support higher volumes of EMLs and other indium phosphide-based devices, including CW lasers and coherent components. Recently, we received a substantial order for 200 Gb LAN speed EML chips, which we expect to fulfill in the December quarter. Overall, we expect 2026 to be a breakout year for laser chip sales at both 100 Gb and 200 Gb LAN speeds. Shipments of our narrow linewidth lasers, which are critical components for ZR and ZR+ modules, have now grown for six consecutive quarters. While our manufacturing capacity for these laser assemblies continues to ramp, demand is outpacing supply and is expected to do so through the rest of fiscal 2026. In addition, we saw sequential growth in shipments of other coherent components for long-haul data transmission, as well as in pump lasers for subsea and terrestrial applications. This momentum in our components business reflects the accelerating global build-out of cloud infrastructure and highlights Lumentum's key role in powering that expansion. We are also positioning ourselves for longer-term growth, particularly in three significant areas: cloud modules, optical circuit switching, and co-packaged optics. In cloud modules, we surpassed our goal to grow revenue by 50% quarter- over- quarter. This contributed approximately half of the sequential revenue growth in the period. We ship cloud modules to all three of our major hyperscale customers, and we expect shipments to grow sequentially in the coming quarters. In optical circuit switches, or OCS, we recognize our first revenue in the quarter with shipments to two hyperscale customers. Not only is our order book expanding with these two customers, but we now have a third hyperscale customer committed to deploy our OCS product in calendar year 2026. Our leadership in optical performance, particularly in 300x300 form factors, has allowed us to capture volume opportunities earlier than competitors. As a result, we are accelerating the expansion of our in-house OCS manufacturing capacity to meet the high level of demand. Our commitment to co-packaged optics, or CPO, is stronger than ever. We just received the largest single purchase commitment in company history for our ultrahigh-power lasers, and we have already announced additional investment in our U.S.-based indium phosphide wafer fab to support it. Our investments in this facility will position us for a significant revenue ramp in CPO by the second half of calendar 2026. We expect to continue to make vital contributions to U.S. technology competitiveness through leadership in optical innovation, strategic partnerships with hyperscalers, and contribution to domestic AI infrastructure. Now, let me move to our industrial tech segment. Industrial tech segment revenue decreased 6% sequentially, but was up 6% from the same quarter last year. Industrial laser declined quarter- over- quarter. 3D sensing declined as well, following expected seasonal trends. In Q4, ultrafast laser shipments held steady at near record levels, driven primarily by strong demand from a leading tool supplier supporting high-volume solar cell manufacturing. In the quarter, we launched the PicoBlade Core ultrafast laser platform, which enables infrared, green, and ultraviolet wavelengths within a compact form factor for industrial micromachining applications. Despite the revenue decline in industrial tech, segment profitability improved, primarily due to cost reduction initiatives we announced a quarter ago. With these actions and more focus on the core business, we expect to see improved profit margin in this segment over the next handful of quarters. In summary, Lumentum is entering a period of sustained growth, driven by the rapid adoption of AI. Our strong Q4 performance highlights the effectiveness of our strategy, operational resilience, and the differentiated value of our optical solutions. Today, our components business is a key foundation of our success, and we are well positioned for significant growth in our cloud modules business and to lead in emerging technologies like OCS and CPO. As we scale production, expand capacity, and intensify our focus on high growth, high margin opportunities, we are confident in our ability to deliver continued top-line growth, margin expansion, and long-term shareholder value. Now, I'll hand the call over to Wajid. Thank you, Michael. Fourth quarter revenue of $480.7 million and non-GAAP EPS of $0.88 were both above the high end of our revised guidance ranges. GAAP gross margin for the fourth quarter was 33.3%, GAAP operating loss was 1.7%, and GAAP net income per share was $2.96. Turning to our non-GAAP results, fourth quarter non-GAAP gross margin was 37.8%, which was up 260 basis points sequentially and up 1,000 basis points year- on- year due to better manufacturing utilization and favorable product mix as a result of increased Datacom laser shipments. Fourth quarter non-GAAP operating margin was 15%, which was up 420 basis points sequentially and up over 2,000 basis points year- on- year, primarily driven by improved cloud and networking profitability. Fourth quarter non-GAAP operating profit was $72.3 million, and adjusted EBITDA was $98.7 million. Fourth quarter non-GAAP operating expenses totaled $109.3 million, or 22.7% of revenue, an increase of $5.9 million from the third quarter, and an increase of $7.9 million from the same quarter last year. This growth reflects annual employee cash incentives tied to company performance, along with ongoing investments to scale our operations in support of expanding cloud opportunities. Q4 non-GAAP SG&A expense was $41.7 million. Non-GAAP R&D expense was $67.6 million. Interest and other income was $3.5 million on a non-GAAP basis. Fourth quarter non-GAAP net income was $63.3 million, and non-GAAP diluted net income per share was $0.88. Our fully diluted share count for the fourth quarter was 72 million shares on a non-GAAP basis. Turning to the full year results, fiscal 2025 net revenue was $1.65 billion, which was up 21% from fiscal 2024. GAAP gross margin for fiscal 2025 was 28%, GAAP operating loss was 10.9%, and GAAP diluted net income per share was $0.37. Full year fiscal 2025 non-GAAP gross margin was 34.7%, which was 450 basis points up relative to fiscal 2024 due to higher overall demand and factory utilization. Fiscal year 2025 non-GAAP operating margin was 9.7%, up 1,030 basis points from fiscal 2024 due to higher gross margin and improved operating leverage. Fiscal 2025 non-GAAP operating income was $160.1 million, and adjusted EBITDA was $264.2 million. For fiscal 2025, our fully diluted share count on a non-GAAP basis was 71.2 million shares, non-GAAP net income was $146.4 million, and non-GAAP diluted net income per share was $2.06. Turning to our balance sheet, during the fourth quarter, our cash and short-term investments increased by $10 million to $877 million. Our inventory levels increased sequentially to support the expected growth in our cloud and networking revenue. In Q4, we invested $59 million in CapEx, primarily focused on manufacturing capacity to support cloud customers. Turning to segment details, fourth quarter cloud and networking segment revenue at $424.1 million increased 16% sequentially and 67% year- on- year. Cloud and networking segment profit at 23.6% increased 360 basis points sequentially and increased 1,350 basis points year- on- year on higher revenue and favorable product mix. Our fourth quarter industrial tech segment was at $56.6 million, which was down 6% sequentially and up 6% year- on- year. Fourth quarter industrial tech segment profit of 6% increased sequentially on stringent cost initiatives despite lower revenue. Industrial tech segment profit increased year- on- year on higher revenue and the benefit of these cost initiatives. Now, let me move to our guidance for the first quarter of fiscal 2026, which is on a non-GAAP basis and is based on our assumptions as of today. We anticipate net revenue for the first quarter of fiscal 2026 to be in the range of $510 million - $540 million. The midpoint of this range represents a new all-time quarterly revenue record for Lumentum. Our Q1 revenue forecast reflects the following expectations: cloud and networking expected to be up sequentially with strong growth across our portfolio of products addressing cloud and AI applications, and industrial tech to be approximately flat sequentially with a modest decline in industrial lasers offset by a seasonal uptick in 3D sensing. We project first quarter non-GAAP operating margin to be in the range of 16% - 17.5% and diluted net income per share to be in the range of $0.95 - $1.10. Our non-GAAP EPS guidance is based on a non-GAAP annual effective tax rate of 16.5%. These projections also assume an approximate count of 75 million shares. With that, I'll turn the call back to Kathy to start the Q&A session. Kathy. Thank you, Wajid. To allow as many as possible an opportunity to ask questions, please state one question and one follow-up. Now, Regen, let's begin the Q&A session. Of course. We'll now begin our Q&A session. If you'd like to ask a question, you can do so by pressing star one on your telephone keypad. If you'd like to remove your question for any reason, you can do so by pressing star two. Once again, to ask a question, please press star one. As a reminder, if you are using a speakerphone, please remember to pick up your handset before asking your question. Additionally, we will be limiting questions to one question and one follow-up for the remainder of that Q&A session. We'll now briefly pause as questions are being registered. Our first question comes from Simon Leopold of Raymond James. Your line is now open. Thank you very much. Thanks for taking the question. First one, I wanted to talk a little bit about the OCS award. My recollection is that you previously suggested you'd see first revenue in the December quarter. This is two quarters earlier than what we were thinking, and we were thinking one customer, not two. I'd love to get an update of how to think about the trajectory in that. Should we be envisioning a very gradual ramp? How should we think about the trajectory and the potential of this new product category? Thank you. Hey, Simon. Thanks for the question. Yeah, I think we're doing a bit better than we expected, certainly in the customer count, and now, you know, with a third customer coming online, we feel pretty good about things. The way I would characterize it is I think these current quarter, next quarter, and the December quarter are still ramping. We're ramping because we're building our capacity in Thailand to support the customers. I think that we'll start to see more meaningful revenue, meaning very, very significant revenues in Q1, Q2, and then certainly in the back half of calendar 2026. It is a ramp. There's some gradualness to it. There's a couple of inflection points. The first inflection point is probably early in 2026, but then a more meaningful inflection point in the back half of 2026. Right now, we're honestly limited by how many we can build, right? We're trying to ramp this thing very quickly to see a tremendous level of demand, but we are limited by how much we can supply. Thanks. As a follow-up, I wanted to check in on the CPO opportunity as well. It sounds like it's progressing. Last we spoke, it sounded like you were the only approved supplier in the ecosystem for the high-powered laser. Wondering how you're thinking about your position in that market in terms of quantifying as well as your ability to remain a sole source supplier. How's the competitive landscape? Thank you. Yeah, Simon, you and I talked about it. We feel good about our ability to maintain a competitive moat here for two reasons. One, there's a unique power level that this laser throws off, but more importantly, is the reliability. We're able to translate a lot of what we've done from undersea lasers and Raman pumps into this particular product line. It's development. It's leveraging a lot of the same development concepts that we had there. We feel good about the competitive moat. You called it out well. I think we said in the prepared remarks, we would expect meaningful revenue from this again in the second half of calendar 2026. We are seeing, you know, we talked about the order, a very significant order. We are seeing early shipments. At least as far as we know, we're sole sourced. We believe we have a good competitive moat that will keep us in that position. Thank you. Thank you, Simon. Thank you. Our next question comes from Tom O'Malley of Barclays. Your line is now open. Thanks for taking my question. It sounds like the trajectory to the $600 million is moving a little bit forward to the fourth fiscal quarter. Maybe you could walk through the contributions to the $600 million. In the quarter, EMLs were a bit better, but modules were also good as well. Maybe walk through the moving parts of where you see the upside to get you to that $600 million. Yeah, Tom. I mean, I think, you know, number one, we actually expect continued strength in our components business. Our components business carried us pretty significantly this quarter, and we actually are pretty excited about that over the balance of the fiscal year. The cloud modules will definitely be a step up. I think we had a really big step up this quarter of 50% sequential gain in terms of top line. I think we'll hit a little bit of an add here in the next quarter, but then we'll see a pretty dramatic acceleration in cloud modules in our December quarter, March quarter, and June quarter. As we said a second ago, we also expect OCS to layer in. We start to see revenue, meaningful revenue contributions in the first half, significant revenue contributions from OCS in the second half. Still strength in our transport business. It's multifaceted, but if I was going to pick the two or three areas, it would certainly start with components. Cloud modules will be strong, and then I think we're going to see that revenue contribution from the optical circuit switch. Helpful. I kind of wanted to address a little bit of a non-stop. I do. I just wanted to address a press release that came out in the last week. Apple was talking about investment in the U.S., and there was a press release specifically out with one of your competitors with their lasers out of a U.S. manufacturing site. Traditionally, you guys have always been kind of first to innovate there. I was curious, do you guys see a future in which that type of business becomes more significant for you, or do you think that this is an announcement that is talking about existing infrastructure that's in place versus new opportunities that are kind of burgeoning? Thank you. Yeah, I mean, it's an interesting one. You know, in the macro, I think Face ID and 3D sensing will be a minimal part of our business on a go-forward basis. The main story, Tom, as you well know, is everything we're doing in the data center with Lumentum's business. That being said, interestingly, we feel like we're picking up share and decent gross margins on this cycle, and then there's some design changes that are happening in the next couple of calendar years. To your point, we feel like we have an innovation lead. I was on the other side of this, as you know, in Sherman, and you're right. Lumentum has a history of out-innovating, and as long as we kind of keep that innovation engine up, I feel better than I have in a while in terms of gaining share in that business and actually increasing top line and margin in that business. Thank you, Tom. Thank you. Our next question is from Samik Chatterjee of JPMorgan. Your line is now open. Hi. Thanks for taking my questions and congrats on the results here. Maybe for my first one, Michael, if I can press you a bit on the timing of the $600 million revenue guide here for fiscal Q2 2026 because you did have a strong sort of $50+ million quarter-over-quarter increase into the June quarter, and now you're guiding it for September to like a $40 million increase at the midpoint, $40 million or more. I'm just wondering, given your comments about acceleration in terms of Datacom chips with more capacity coming on, and there's the cloud-like business as well accelerating into December and March, is there any other part of the business that necessarily slows down to sort of push that timeline to the June quarter, or is there a potential of achieving that target in the March quarter itself? I have a follow-up. Yeah, it's a very good question. I think there was a very key parenthetical phrase that we had saying the June quarter or earlier. That was, that's an important, important phrase. Look, we feel pretty good about the business across the board. I think we're still in the early innings of our cloud module business. We feel like we're just beginning to scratch the surface in terms of picking up share on that. We talked about OCS in some of the previous questions. We really, really feel good about that business. You've called out in your comments on components. That's going gangbusters. Outside of our industrial tech business, which has obviously had some headwinds in Wupen’s platform, I don't think there's a single sector right now that I could point to that said we're going to be down. Our slope is definitely up, and you can kind of draw your own conclusions as to where you think we end up, but we definitely are on a pretty good run at the moment. Got it. For my follow-up, do you have any thoughts? Yes, please. My follow-up was really on any thoughts you have on the semiconductor tariffs or Section 232 investigation, whatever you want to call it, in relation to speculation around 100% tariffs on semiconductors given your fabs in Japan. I did see you made an announcement of a different investment here in the U.S. advanced optics and how you're thinking about the likelihood of being exempted from any potential tariffs on the semiconductor side given your location of fabs. Any thoughts on that would be useful. Thank you. Yeah. I mean, Tom, as you can see and appreciate, during the quarter, the tariff situation is pretty fluid. There's a lot has happened even after we announced our updated guidance in June. Having said that, we've gone back and taken a look at the new regulations that have come out and taken a look at the exempted categories that are in the appendix to that new guideline. We've determined that our products are exempted from any of the tariffs that would be applicable in that new guidance. We're fairly comfortable that we will not be impacted. Like I said, things are fluid. We thought at the beginning of Q4, we would have a 100 basis point, up to a 100 basis point negative impact from tariffs. Yet, in Q4, we actually had minimal impact of tariffs. Even in Q1, we put in a little bit just in case something new pops up in the remaining part of August and September. We'll see at the end of the quarter where that ends up. For now, no material changes in our business operations or the impact from tariffs would be our view. Thanks, Tom. Regen, we'll take our next question. Of course. Our next question is from Blaine Curtis of Jefferies. Your line is now open. Hi. Ezra Reader on for Blaine, thanks for taking my question. I guess a two-parter instead of a follow-up. First, you talked about a big 200 Gb EML order in December and then also discussed that you're going to see a big ramp next year in 100 Gb and 200 Gb. Can you talk a little bit about what you're seeing timing-wise between the two of those in that transition? The follow-up question is kind of your lead times and visibility into both demand in those ramps and kind of inventory for both of those. I'll take that and then Wupen will add some colors. The first thing that I would say is obviously the 100 Gb is run rate. We're shipping that right now. It primarily goes into 800 Gb transceivers, and we feel like that is continuing to go well. We're seeing those numbers climb. We're seeing our EML shipments on 100 Gb continue to climb. 200 Gb is more associated with 1.6 T, and we're starting to see early ramp of 1.6 T. This now is related to our components business. I think our module business as it pertains to 1.6 Tb would feather in next year, but we are starting to see early shipments of 200 Gb per lane into the 1.6 Tb transceivers. That's additive business. We see that on top of what we already have for the 100 Gb. The 100 Gb will continue to climb, and the 200 Gb will layer in on top of that. We talked about through the questions and even in the prepared remarks, the strength in our components business. We have a baseline of 100 Gb. We have a nice layering of 200 Gb per lane, and we layer on top of that this co-packaged optics opportunity, which we feel really, really strongly about. There's a nice effect here in our components business that is obviously a nice margin driver for us. Wupen, can you comment a little bit on the dynamics? Thank you, Michael. Yeah, definitely. I think it's really important to keep in mind that there's no transition, you know, down and up kind of situation. It's layered on top of. 100 Gb is running very, very strong. Most hyperscalers are still on the 100 Gb platform and for probably the next couple of years at a minimum. 1.6 Tb is just getting started. It's really additive to our revenue going forward. Our visibility into the future business actually is really good. We have, you know, six to nine months of visibility, if not longer. The general consensus, what we can see in the market is that we are in a supply constrained situation. Therefore, we would anticipate the laser demand will continue to be very, very strong and will continue to see very good visibility going forward. Of course, given that situation, inventory is very low. We're basically keeping everything that we can make and try to keep our customers satisfied for their deployments. Ezra, did you have a follow-up question? Nope, that was it. Asked my two. Okay. All right. Thanks, Ezra. Regen, we'll take our next question, please. Of course. Our next question is from Christopher Rowland of SIG. Your line is now open. Hi. This is Aaron Nakbo in for Chris Rowland. Thanks for taking my question. On the EML competitive landscape, there are a few EML players out of Japan in addition to your largest competitor. How do you believe you are positioned to retain your edge and leadership here? Yeah, look, I think there are two dimensions in the EML business. One is certainly performance. I think if you look at our design, it is the best performing. Where that translates is in module yield. Our customers typically report a significantly higher yield on their cloud modules using our EMLs over competitors. That allows us some pricing latitude, which has been super favorable. Lumentum's been able to use that to great effect. We feel like we talked about 200 Gb. We feel like we're leading on technology innovations, 200 Gb, CPO. As Wupen described in the last call, these are all layering on top of each other. The second element is obviously capacity. We are the biggest supplier in terms of capacity. We have our fab in Japan is outputting more EMLs than I think any other location. We really feel good about our ability not only to lead technically, but also to lead operationally. That's giving us a pretty nice tailwind as we head into the next handful of quarters. Did you have a follow-up? At your investor briefing at OFC, you had a slide where you showed your segment mix at over $500 million of revenue. At that level, telecom and Datacom both represented 45%. Given the September guide, how are you tracking to that mix? We're tracking pretty well in line. Datacom is probably running a little bit ahead of telecom, not really demand-determined, more related to some of the supply constraints we have on the telecom side that we are looking to close on. I think from a demand standpoint, the 45% and 45% are correct, but in terms of what we're actually shipping, we're a little bit more tuned to Datacom because some of the capacity improvements on the telecom side still need to happen for us. There is an underlying, you know, the demand is really mostly coming from the hyperscalers on the cloud. Even though the customers are traditional telecom customers, the source of demand is really from the cloud. I think that's very important, that dynamic, you know, that we should consider our business going forward. That's a good point. Well said. Yeah. Great. Thank you. Regen, I think we'll take our next question. Thank you. Our next question is from Meta Marshall of Morgan Stanley. Your line is now open. Great. Thanks. Apologies for the background noise. Just a couple of questions for me, and I'll just say them both at once. Just in terms of kind of the, you know, you had a lead customer on the optic transceiver side. You clearly talked about kind of supplying the additional two customers this quarter. Just how should we think about kind of the ramp of additional customers, just given kind of how strong the demand of customer one has been? Maybe just as a second question, you know, particularly strong gross margins this quarter. Just trying to get a sense of, you know, like directionally, is that more mixed? Is it more yield improvement? Just how to kind of think about kind of capacity for that to increase further. Yeah. Meta, thanks for the question. Look, on cloud modules, we're obviously trying to be disciplined. We're continuing to focus on opportunities that yield the highest margins for us. We also are somewhat constrained in terms of our ability to produce. We are focused on these three customers. Our capture rate of additional customers probably in the near term will be modest. I think we're going to continue to look at these three guys both in terms of the high-value SKUs that we can deliver to them. Again, just because our capacity, both from an engineering capacity and from manufacturing capacity, is somewhat constrained. That being said, we still expect to grow and actually grow very significantly in that business over the coming handful of quarters. The second part of the question was on gross margins. Yeah, look, it's a big focus for us. I think we saw improvement on mix, mixed with some of it because of the components business, but a lower piece of our business, a lower margin piece of the business, and cloud modules contributed about half the growth. Still, we showed margin improvement. We continue to be on that trajectory. We're spending a lot of time, Wajid and I, together with Wupen and his general managers, are very, very focused on cost improvements of all of our products, pricing when we can apply leverage when it's appropriate. We would expect to see some more significant gross margin step-ups in the ensuing quarters. This is a big, big area of focus for us. Thank you, Meta. That's great. Thank you. Regen, I think we'll take our next question. Of course. Our next question comes from Ryan Koontz of Needham & Company. Your line is now open. Great. Thanks. I want to ask about the telecom side of the world. Obviously, ZR is the main driver there. I wonder if you have any commentary on how fast you think that market's growing. Can you expand on your opportunities in that market from a component perspective and how you think about that business over the next 12, 18 months? Thank you. Yeah, I mean, it's been a big story for us. I'll let Wupen add color here. Obviously, our narrow linewidth lasers, which are a key component in ZR and ZR+ modules, have done very, very well. We said in the prepared remarks we're capacity limited. We are. We're sold out for really the balance of the fiscal year, to be honest with you, at this point. That has been where we've played. Our actual modules have not done as well. We've actually tried to sell ZR+ modules ourselves. We've not done as well. It's definitely a margin hit to the company. We are focusing where we can on selling components into the DCI market. I don't know, Wupen, you want to add some color on how you're thinking about it? Sure. First of all, I think the DCI market is growing very rapidly. There's a very, I would say, a general trend now for most of the hyperscalers to resort to the DCI kind of architecture, moving away from traditional transponder-based architectures. We think that as a market, the ZR pluggable modules is a long-term trend that continues to go up. From a growth rate perspective, we're forecasting roughly about 30% volume annual growth rate, number one. Number two, with the DCI traffic now growing rapidly to carry the AI traffic, we see the 800 ZR now starting to be of interest to multiple hyperscalers. As Michael said, we're not so focused on the module side, but we're definitely looking for opportunities on the component side to participate continuously going forward in the 800 ZR market as well. Thanks, Ryan. Did you have a follow-up? Yeah, just a quick question about transceivers and, you know, share for EML designs versus, you know, VCSEL and Silicon Photonics. Do you pick up any share shifts from a demand perspective going on with this migration to higher speeds, maybe due to the AI infrastructure? Thank you. Yeah, I mean, again, I'll have Wupen add color here, Ryan, but we keep hearing noise of this, and frankly, we're not seeing it. I mean, we are sold out on our EMLs, again, for the balance of the year when we're, you know, customers are coming to us for allocation. We're actually just trying to pick and choose because we only have so much capacity, and it's actually sold out. The Silicon Photonics is doing well. There's no doubt about it. It's layering in in the transceivers into the data center, but it has not impinged on EML demand in any way. I mean, how are you thinking about it as you think about 1.6 Tb and beyond? How are you thinking about these two things feathering? Thank you, Michael. I think number one, as we talked about earlier, there is a major supply constraint. In the sense that Silicon Photonics versus EML, it depends on what laser you can get. That would dictate your solutions that you would be able to deploy. That's actually really happening now in the 100G per lane speed products. Going forward, 200G per lane, 1.6T, just getting started, certainly there are equal amounts of EML-based design and Silicon Photonics-based design. I think a similar dynamic will play out. I think we're in a very early phase of 1.6T. I would say that probably at this point, both technologies are being deployed. I think the supply situation will determine to a large extent what technology will be used in reality. Thanks, Ryan. We have Regen. We'll take our next question. Thank you. Our next question comes from David Vogt of UBS. Your line is now open. Great. Thanks, guys, for taking my question. I have two questions. Thank you. Maybe, guys, can you talk about where you actually stand from an EML wafer fab capacity? I know in the past you've talked about expanding capacity, but I think upwards of 40%. I think I just heard Michael say that we're completely sold out. Where do we stand today, and how do you think that kind of plays out? Along those lines, the second question is related. When you think about the pricing dynamics, given the limited supply of wafer chips going forward, how much should we think about that being an impact on gross margin going forward from a pricing perspective? Obviously, you need to be careful in terms of how you price, but just trying to get a sense for how should we think about that as we go into fiscal 2026. Thanks. Yeah, I think, you know, let me talk a little bit about the capacity. We are still transitioning from 3 in to 4 in wafers. That's something that's undergoing. We think we can bump our capacity completing that transition, and that will give us another leg up in terms of capacity. We definitely feel like the economics are in our favor, right? There's limited supply. There's a lot of demand. We do feel like there's a price lever. We've been very careful because there's only a handful of customers that are there. As we think about the situation over the next handful of quarters, I do think Wajid and Wupen are thinking about how to make this work out more equitably, right? Given that we have finite capacity and a lot of demand, price, I do think, will become more of a meaningful discussion in the next handful of quarters. David, just to be clear, those pricing discussions are not incorporated into Michael's earlier comments around 40% gross margins, as well as our comments about achieving $600 million of quarterly revenue. Pricing increases would be upside to that. Yeah, I will also comment that capacity ramping continues. We have made an investment into the fab side, and we believe it's a strategic investment for us. We are looking at a few times the capacity over the next several years as we transition also over to the 6 in wave and the above-side substra Thank's David. Kathy, can I stick one more in? Sure. Why don't you go ahead? Just on OCS, obviously, it's exciting to hear about a second customer and then a third customer coming online. How should we think about sort of the arc of the profitability of that particular product offering as it expands from one hyperscaler to two to three, you know, into next year? Is this kind of a corporate average kind of product cycle? Just trying to think how we should think about what the impact is in 2026 and 2027 from OCS. Yeah, it's significantly above corporate margin averages. It will be most definitely accretive. With any factory, you've got ramps and how we absorb the factory. Assuming a reasonable level of volume, and reasonable level of volume that we've described starts really in the first half of calendar 2026, this will be accretive to our margin line. Great. Thanks, Michael. Thanks. Regen, p lease go to the next question. Of course. Our next question is from George Notter of Wolfe Research. Your line is now open. Hi, guys. Thanks very much. I was curious about just the capacity expansion down at the Noida facility. Any insights you can give us there in terms of scale, capacity, new additions would be great. Yeah. We are obviously, we've built a new building in Noida. That building has three floors. We've actually started to outfit the first floor. We feel like even given the volumes that we're seeing from our hyperscale customers in dealing with that first floor, that should be able to, one, meet the demand levels that we're seeing, and two, give us some flexibility. As you know, George, right now, a lot of our cloud modules are coming from China. That will give us some flexibility from a manufacturing footprint to move to Thailand and help should the tariff situation change. It is early innings. We'd expect that to come online sometime next year where we'd have that additional capacity available to us from a manufacturing standpoint. Got it. Super. One other quick one. I think you mentioned at one point you were looking at doing some portfolio cleanup or, you know, adjustments. Is that something that you are indeed looking at? Is there any timelines or things you might be particularly focused on there? Thanks. Yeah. We announced some changes, I think, in my first earnings call around metrology, X-rays, spectroscopy. We shut some of those businesses down. This is an ongoing process. As you know, we're just starting our fiscal year. Wajid and I have set the AOP. There will be some portfolio management that will be part of that, and we'll be talking about that, I think, in subsequent calls. It's an important tenet of our strategy to really try to focus on our cloud networking business under Wupen as much as possible and really figure out the parts of his portfolio that are going to be the most profitable and lead to the longest-term growth. We will have some discussions, I think, in the next couple of calls around some portfolio management moves that we are in the middle of at the moment. Thank you. Thank you, George. Regen, we'll take our next question. Of course. Our next question is from Vivek Arya of Bank of America Securities. Your line is now open. Thanks for taking my question. Michael, how large is the cloud module business now, and how large does it need to be for your quarterly sales to get to $600 million? At that point, you know, will it be levered to a single customer, or will it have multiple customers? Yeah, I mean, I'll let Wajid and Kathy sort of describe the size. I mean, I think we've discussed it with you, Vivek, at the last conference. You know, the number went up 50%, and we would expect it to continue to grow, as we said in the prepared remarks. I think that from here, it doesn't actually need to grow a whole lot for us to get to the $600 million number. Previous caller said, "Look, you guys are at $525 million at the min," right? It's another $75 million of incremental growth, and we've said that we would expect components to contribute to that. We would expect OCS to contribute to that. I do think that this cloud module business will grow. It is continuing to grow. We are being disciplined about it. Wupen is being super smart about which opportunities he takes and which he doesn't. We are expecting revenue contributions from our largest customer, from our second largest customer, and frankly, from our third largest customer. I think it was Meta that asked, at least right now, for the next handful of quarters, we do not expect to add customers beyond these three. Does that give a follow-up question? Yes. Thank you, Kathy. A follow-up on gross margins. Wajid, how are you thinking about gross margins heading into September? When you do get to the $600 million quarterly run rate, do you think gross margins can get close to 40%, or is there a different mix that we should be thinking about? Thank you. Yeah. No, Vivek. We've been able to improve our gross margins sequentially for the last number of quarters. The most recent quarter, we were at 37.8%. We'll probably see a little bit of a nudge up to that moving into Q1. As we approach the $600 million of revenue, like Michael mentioned, we don't actually need a lot of growth in cloud modules to get there. Probably in the range of $20 million or $25 million is about all we need in order to be able to get to the $600 million target. Because of that and the focus really being on the components business getting up to $600 million, we should see a nudge up again on gross margins, getting us close to the 40% that we outlined in the April OFC presentation where we said that we thought at $600 million would be between 37% and 40%. Just given the mix that we're seeing in front of us, we should be at the higher end of that range when we get to $600 million. You've got to remember, Vivek, one of the things that's actually a headwind to our margins right now is that we're spending about 150 basis points every quarter just on NPI. As we're ramping these second and third customers that we're not recognizing revenue for at this point in time, both in cloud modules and OCS, there's a significant amount of NPI costs that are not being absorbed by inventory right now. As the business grows, some of that NPI cost as a percentage of revenue should come down. That'll certainly help us as well. Thanks, Vivek. I think we have time for one more question, Regen. If you could do one more question and then pass the call back to me. Of course. Our last question for today's call is from Ananda Baruah of Loop Capital Markets LLC. Your line is now open. Yeah, thanks, guys. Appreciate it. I guess maybe this could be Michael and Wajid, just kind of sticking there. Is there a sort of theoretical mix of transceivers, of modules, relative to components that you think about as you've seen, Michael, the last handful of months, sort of this new model? How How they come into shape? Would love to get any thoughts there. I recognize it could change over time, but just whatever your current thoughts are. Thanks. Yeah, I mean, I don't know that we think about it that way. What I would say is, you know, we are going to continue to be selective in the cloud modules that we take on. We are limited to these three customer engagements that we have. Within those customer engagements, we've asked Wupen to be very smart about which of these opportunities he prosecutes. You know, we expect to continue to grow this business, and I would say grow it relatively significantly throughout this fiscal year. As Wajid just elucidated, we do expect to grow gross margins as well. This will be a gross margin drag. I mean, I think in our best case, we've said to people we expect this business to be maybe pushing 30% gross margin in the asymptote. We will see a drag from it. We want to limit how much we do there. We want to focus on the components, focus on OCS, focus on the CPO opportunity. Beyond that, obviously, Wupen is keenly, keenly focused on scale-up, which is another component opportunity. We do think that this could help us from a cash flow perspective and from a revenue growth perspective, at least for the next four to eight quarters. Wajid, do you have any additional color? No, I think that's right. At least as it relates to the $600 million a quarter, thinking about it as being about 15%- 20% of company revenues is probably the right level. Network interconnect, or sorry, cloud interconnect, our Datacom chip business really growing with our supply. As the supply improvements happen, 3 in to 4 in that Michael talked about, as well as some new CapEx that we've got coming in both in our fiscal Q3 and Q4, that business should naturally grow along with the 200 Gb EML. The cloud interconnect business, the Datacom laser business, will be larger as part of the $600 million mix than our cloud module business will be. I think the component business, they are just the cloud chip business. There is also other laser business, which is also going to grow meaningfully, right? I think the future of the growth, again, in the context of $600 million, will be some portion coming out of the module as what you talked about and Michael talked about, but also a meaningful chunk of the component, not just cloud component per se, but also so-called telecom component that goes into DCI that also supports the AI machine learning growth. All these areas are going to be growing and then giving us an uplift of gross margins. Thanks, Ananda. Do you have one follow-up that we can? Thank you. I guess the question would be just OCS. In terms of materiality, I think Michael made comments back at OFC that in some context, it could be a noticeable product line. Just wanted to get his context about how noticeable it could be over time. Thanks. Yeah, I mean, look, we are very optimistic this will be, you know, a multi-hundred million dollar contributor for us. What timeframe, it's becoming increasingly sharply clear that it's sooner rather than later. We haven't put a timeframe on that. Certainly, the opportunity for us is measured in multiple hundred millions, and we feel pretty good about that, just being able to step into that TAM in a meaningful way. All right, thanks so much. Thanks, Ananda. Great. That's all the time we have for questions. Thank you. We look forward to connecting with you at upcoming investor conferences and meetings this quarter. I'd like to thank you all for joining us today. Thank you. That will conclude today's call. Thank you for your participation. You may now disconnect your line.
