Thank you, Kathy, and good afternoon, everyone. We exceeded the midpoint of our guidance for both revenue and EPS for the fourth quarter. We booked record orders for Datacom chips used in data center applications and saw emerging positive trends in the broader networking market. We made significant progress in executing our strategy to grow our cloud business and broaden our customer base, including new and substantial cloud and AI module opportunities. Lumentum is emerging as a leading provider of photonics solutions for cloud data center operators and AI infrastructure providers. Our comprehensive photonics portfolio built on differentiated in-house technology and proven volume manufacturing delivers innovative solutions that address the critical challenges of connectivity bottlenecks and power consumption. To achieve our cloud and AI goals, we are implementing a three-pronged strategy. First, we are focused on expanding our customer base to include multiple data center operators and AI infrastructure providers as they migrate to higher speeds. Second, we are scaling up capacity for component and module production at established Lumentum facilities outside of China. And third, we are executing on our differentiated technology roadmaps to support data center compute scaling across future generations of optical interconnect technologies and data center architectures. I would like to elaborate on our progress in each of these areas. Our first priority is to expand our customer base within the data center market by leveraging our advanced high-speed optical transceiver capabilities and proven laser transmitter components. As the industry transitions to higher speeds, our differentiated technology becomes increasingly valuable to these customers. Within data centers, the shift to 200G lane speeds, particularly in 1.6T optical transceivers, plays to our strengths. The growing importance of single-mode optics and in the Indium Phosphide lasers, driven by the limitations in multi-mode optics, aligns well with our market and technology leadership positions. Our industry-leading 100G EML transmitter components have established a strong reputation for performance, quality, and reliability and are currently shipping in record volumes. Our proven capabilities position us favorably as the industry adopts 200G per lane technologies. Our 200G EMLs are being qualified by multiple customers for integration into their transceivers and subsequent deployment in a wide range of cloud and AI infrastructures. We anticipate being a key laser supplier in initial 1.6T transceiver deployments as we ramp up 200G EMLs later this fiscal year. In Q4, we achieved record volume shipments of EMLs and secured substantial bookings, which we will be working to fulfill throughout fiscal 2025. This includes initial orders for 200G EMLs from leading AI customers. Based on this momentum, we foresee continued strong EML shipments throughout fiscal 2025 and into fiscal 2026. Additionally, we are supplying differentiated laser sources for silicon-metonics-based transceivers, further broadening our content opportunity within the data center market. We've also made significant progress on our newest 800G and initial 1.6T transceiver product developments. We are deeply engaged with multiple customers and we have received favorable feedback after providing product samples to these customers. We have secured a major award with one new customer and are actively working to finalize additional awards with multiple customers. The second prong of our cloud strategy involves expanding manufacturing capacity for both optical transceivers and optical components at established Lumentum facilities outside of China. This expansion is critical to supporting our cloud customers' growing AI and cloud workloads while ensuring supply chain security. As mentioned earlier, Indium Phosphide lasers are essential for scaling data center infrastructure. Due to overwhelming demand for our critical technology, our Indium Phosphide capacity is fully subscribed at least until the end of calendar 2025. Therefore, we can only meet this demand by growing capacity. In the current fiscal first quarter, we have already invested $43 million in our Indium Phosphide wafer fab facilities and we expect to continue to invest in our Indium Phosphide capacity over the next several quarters to keep up with the growing demand for these enabling laser technologies. Although the industry faces a broad shortage of Indium Phosphide lasers, over time, our capacity additions will help mitigate these constraints. However, we anticipate that our production output will remain on allocation through at least the end of calendar 2025. Our significant capacity expansion for optical transceivers in our facility in Thailand is progressing as planned with the first production line scheduled to start operations this quarter. Based on current engagements with multiple hyperscale cloud operators and AI infrastructure customers, we expect to complete additional phases of our manufacturing capacity expansion over the next 18 months to keep up with the expected strong demand. Finally, the third prong of our cloud strategy focuses on delivering differentiated technologies to address the evolving challenges of data center scaling, encompassing both increased data link capacity and enhanced energy efficiency. We are actively collaborating with leading-edge customers to deliver breakthrough technologies that will support multi-year cloud and AI infrastructure roadmaps. Optical switching, a critical component of future cloud and AI networking architectures presents a significant opportunity for us at Lumentum. Our optical switch products in development offer advantages in power efficiency, increased bandwidth, reduced latency, flexibility, and agility. We have shipped evaluation units to multiple customers and the initial feedback has been overwhelmingly positive. Another key technology area is enabling the transition to high density, low power optical links for future generations. Our ultra-high power laser technologies have attracted considerable interest from cloud and AI infrastructure customers developing high density optical interconnects. Our heritage of delivering high performance, high reliability lasers in a high volume production environment positions us favorably for this emerging market. Lastly, we are focused on enabling the shift to speeds beyond 200G per lane, such as the 400G per lane generation. Our advanced Indium phosphide and photonic integrated circuit capabilities honed through years of experience in data center and high-performance telecom applications are essential to meeting future demands. While the deployment of these products and technologies is a few years away, these are long-term developments requiring early investment and close customer collaboration. We are actively engaged with customers and their R&D teams and together we are shaping the future of optical technology. Now let me move to additional fiscal fourth quarter revenue and product highlights. As expected, our cloud and networking segment had a challenging quarter with revenue declining 19% sequentially and 11% year-over-year. While overall demand for telecom products was soft in the quarter as expected, we are encouraged by several positive trends emerging within this part of our business. We saw an increase in shipments for narrow line with tunable lasers used in 400ZR modules for data center interconnect applications. With our design wins, we anticipate maintaining a leading market share position in laser components for ZR and ZR plus applications this fiscal year and in the coming years. While there are still lingering industry inventory challenges, we are encouraged by recent indications of improvement in the traditional networking market. Recent weeks have brought increased customer demand for our newest leading edge coherent transmission and next generation transport products along with continued signs of customer inventory normalization. Consistent with this, advanced ROADM demand is showing promise with growing demand for integrated C+L band solutions and high port count ROADM products. In leading edge coherent transmission, we are seeing excellent demand trends for 130-gigabyte coherent products and encouraging early traction with our 200-gigabyte products. This is driven by customer demand for increased capacity and spectral efficiency fueled by continued bandwidth demand growth. Our broad set of design wins and differentiated technology and manufacturing capabilities position us for continued leadership in these important products in the coming years. We expect our cloud and networking business to show sequential improvement in fiscal Q1. Now let me move to our industrial tech segment. Our industrial tech segment revenue increased 2% sequentially but declined 36% year-over-year as expected. Like others in this space, we continue to face challenges due to the weak end market demand and high levels of customer inventory. In industrial tech, we continue to focus on developing innovative industrial laser products that address rapidly growing applications. The growing demand for higher precision is driving a transition from picosecond to femtosecond lasers. These lasers with their extremely short pulses offer more precise material processing without significant heat damage, opening new possibilities in sensitive applications such as semiconductors, displays, and advanced chip packaging. These market areas are in turn driven by the growth of AI. The immense computational demands of AI require significant advancements in semiconductors and innovative packaging technologies to support high-performance computing. We're actively collaborating with leading semiconductor equipment manufacturers to develop ultra-fast lasers for interposer and advanced semiconductor packaging. In the fourth quarter, we also successfully delivered both high and low power FemtoBlade demo units for advanced display applications. Looking to fiscal Q1, we expect Industrial Tech to be down sequentially due to continued weak end market demand and ongoing customer inventory adjustments with a modest seasonal increase in 3D sensing revenue. To summarize, we have made significant progress in executing our strategy to grow our cloud business. We booked record orders for Datacom chips and are investing in additional production capacity to help us meet customer demand. We have made excellent progress with multiple new high-speed optical transceiver customer engagements, including securing a major transceiver award with one new customer. We are actively working to secure additional awards from other new customers. Our robust pipeline of cloud customer engagements and improving trends in the traditional networking market reinforce our confidence in the target we highlighted on our last earnings call. This is to grow quarterly revenue to $500 million by the end of calendar 2025. We foresee continued significant growth into 2026 and 2027. We are executing on new cloud and AI opportunities that we expect will elevate our cloud business to a multi-billion dollar annual run rate in the coming years. Before turning the call over to Wajid, I want to express my sincere gratitude to all our employees and customers worldwide for their unwavering focus, dedication, and collaborative spirit. With that, Wajid.

Thank you, Alan. Fourth-quarter revenue of $308.3 million and non-GAAP EPS of $0.06 were above the midpoint of our guidance ranges. GAAP gross margin for the fourth quarter was 16.6%, GAAP operating loss was 43.3%, and GAAP diluted net loss per share was $3.72 with a large portion of the GAAP net loss primarily driven by restructuring charges, amortization of acquired intangibles, and evaluation allowance related to certain tax assets. Due to the historical GAAP losses of the company and a backward-looking calculation to determine the requirement for valuation allowances on deferred tax assets, the company determined the need to record a valuation allowance of $139.8 million to its U.S. deferred tax assets on the company's balance sheet as of the most recent fiscal period. Given the business opportunities ahead and the growth expectations Alan highlighted, we believe in the future we will be in a position to release this allowance and use the related asset. To increase investments in programs that accelerate our exposure to significant new AI opportunities, we decided to stop our in-house development of certain communications ASICs, including coherent DSPs and RFICs. We believe we can meet customer needs using ASICs from third-party partners while reallocating significant R&D spending towards new cloud and AI customer programs. As a result of this decision, in Q4 we recorded $35.8 million of restructuring and related charges, including a $29.1 million write-off of in-process research and development and tangible assets. Turning to our non-GAAP results, fourth-quarter non-GAAP gross margin was 32.2%, which was down sequentially and year-on-year on lower revenue. In future quarters, we anticipate company gross margin will sequentially increase as manufacturing utilization improves due to an improved telecom outlook, as well as an increase in Datacom laser shipments. Fourth-quarter non-GAAP operating loss was 0.3%, which was down sequentially and year-on-year on lower revenue. Fourth-quarter non-GAAP operating loss was $0.8 million and adjusted EBITDA was $25.9 million. Fourth-quarter non-GAAP operating expenses totaled $100 million or 32.4% of revenue. A decrease of $4.3 million from the third quarter and down $2.4 million from the year-ago quarter. The lower operating expense in Q4 was achieved despite increased R&D spending on our Datacom transceivers given the strong customer traction that Alan spoke of earlier. Q4 non-GAAP SG&A expense was $35.1 million, non-GAAP R&D expense was $64.9 million. Interest and other income was $5.4 million on a non-GAAP basis driven by interest earned on our cash and investments. Fourth-quarter non-GAAP net income was $4 million and non-GAAP diluted net income per share was $0.06. Our fully diluted share account for the fourth quarter was 68.3 million shares on a non-GAAP basis. Turning to the full-year results, fiscal '24 net revenue was $1.36 billion, which was down 23.1% from fiscal '23. GAAP gross margin for fiscal '24 was 18.5%. GAAP operating loss was 31.9% and GAAP diluted net loss per share was $8.12. Full-year fiscal '24 non-GAAP gross margin was 33%, which was down relative to fiscal '23 due to lower overall demand and factory utilization. Fiscal year '24 non-GAAP operating margin was 2.8% down from fiscal '23 due to lower gross margin. Fiscal '24 non-GAAP operating income was $37.8 million and adjusted EBITDA was $140.5 million. For fiscal '24, our fully diluted share count on a non-GAAP basis was 67.7 million shares. Non-GAAP net income was $68.7 million and non-GAAP diluted net income per share was $1.01. Turning to the balance sheet, during the fourth quarter, our cash and short-term investments increased by $16 million to $887 million. This increase was primarily due to improved working capital performance as we achieved a $22 million sequential reduction in overall inventory levels. In Q4, we invested $24 million in CapEx, primarily driven by high-speed transceiver capacity additions at our Thailand manufacturing site. As we move through fiscal '25 and beyond, we're focused on expanding our high-speed transceiver capabilities and capacity in Thailand to support 800G, 1.6T, and eventually 3.2T transceivers. We anticipate an elevated level of capital expenditures in fiscal '25 to proactively meet the anticipated surge in demand for high-speed transceivers and Datacom components. Turning to segment details, fourth-quarter cloud and networking segment revenue at $254.7 million decreased 18.8% sequentially and decreased 11.1% year-on-year. Cloud and networking segment profit at 10.1% decreased sequentially and decreased year-on-year. Our fourth-quarter industrial tech segment revenue at $53.6 million was up 1.7% sequentially and down 36.4% year-on-year. Fourth-quarter industrial tech segment loss of 0.4% improved sequentially. Year-on-year segment profit declined. Now let me move to our guidance for the first quarter of fiscal '25, which is on a non-GAAP basis and is based on our assumptions as of today. We expect net revenue for the first quarter of fiscal '25 to be in the range of $315 million to $335 million. At the midpoint, we expect to show year-over-year revenue growth when compared to Q1 of fiscal 2024. This Q1 revenue forecast includes the following assumptions: Cloud and networking to be up sequentially, primarily driven by an improvement in telecom networking demand and Industrial Tech to be approximately flat sequentially with decreased industrial laser shipments offset by a modest uptick in 3D sensing due to typical seasonality. Based on this, we project first quarter non-GAAP operating margin to be in the range of 0% to 3% and diluted net income per share to be in the range of $0.07 to $0.17. Our non-GAAP EPS guidance for the first quarter is based on a non-GAAP annual effective tax rate of 16.5%. These projections also assume an approximate share count of 68.8 million shares. Please note this guidance includes certain expenses that were previously excluded from our non-GAAP presentation. Mainly those related to abnormal excess capacity that in Q4 and prior periods were excluded from our non-GAAP results. This change in presentation reduces our Q1 EPS guidance by approximately $0.05 compared with our prior presentation methodology. For clarity, our Q1 non-GAAP EPS guidance of $0.07 to $0.17 includes the impact of the new presentation. With that, I'll turn the call back to Kathy to start the Q&A session.

Thank you, Wajid. To allow everyone an opportunity to ask questions, please keep to one question and one follow-up. Now let's begin the Q&A session.

We will now start the Q&A session. The first question comes from Samik Chatterjee with JP Morgan. Your line is open.

Thanks for taking my questions, and I'll ask both of my questions at the same time. So I guess the first one was in relation to the new customer announcement that you highlighted in your prepared remarks. Can you give us a bit more color in relation to sort of the type of customer, whether it's a web scaler, or how should we think about the type of customer, and how are you thinking about the magnitude of the opportunity relative to the run rate of your module business at this time? And for my follow-up, just in terms of the Q4 to Q1, I think you mentioned sequential growth in telecom. I didn't really hear you talk about any sort of guidance on the Datacom side. So if you can just help us how to think about Datacom between Q4 and Q1, and also if it's not going sequentially, then what is driving the sequential decline in revenue in the Datacom business between Q4 and Q1? Thank you.

Yes, thanks, Samik. I'd say we don't want to comment too much on what type of customer, but you can imagine, we use the word major and big, so it's big. I would say that run rate-wise, I think it comes down to how well we execute. And so, we will earn as much business as we earn from our customer, given our execution, and so far, we're off to a good start. And as I said in the prepared remarks, our operation in Thailand, first production line is ready this quarter. And so, we'll be shipping first units out of Thailand this quarter with qualifications happening, and ramp beginning early part of calendar 2025. So consistent with what we've said in the past. So as far as comparison to run rate stuff, that's really going to be very variable given we have to earn it and we have to execute well with good quality and performance and delivery. So I hesitate to comment more on that, but certainly the customer that we have said, we've gotten the award on certainly consumes a lot and certainly could be as big, if not bigger. On the second question, sorry, go ahead.

It was on the sequential brand in Datacom?

Yes, we're not going to break out Datacom versus Telecom. But what we did say was that we, we've seen some improvements in Telecom. So you can expect that that's going to grow quarter-on-quarter. And as we said in the last earnings call, we're in a product transition. And so the Q4, Q1 numbers are depressed. And so that's coming to fruition and we expect that'll pickup in our fiscal second quarter.

Thank you, Samik.

Thank you. The next question is from Alex Henderson with Needham and Company. Your line is now open.

Thanks. So I was hoping you could talk about the capacity and ramp timing on both the chips business as well as the transceiver business at Cloud Light. My understanding is that coming out of the June quarter, you should be fairly flattish in that business in terms of available capacity. And that new capacity should be coming on stream in the December quarter and ramping starting kind of in the first half of calendar year '25. Can you give us any sense of that cadence and what those plans might look like now versus what they looked like say three months ago?

Yes, as we said, again, in the prepared remarks, we had record bookings for our chip business and we invested $43 million already this quarter in our fab capacity to address that. So you're right. It takes time for that to come online, but we should see incremental capacity in the first half of calendar '25, but in the short term, it's relatively fixed given the cycle time of the fab, et cetera. So I'd say on the chip business where, in fact, in all CapEx, we meet monthly and evaluate if we need to order more or less to hold off. And so that's the discipline we're trying to put into the process to make sure that we have the capacity when our customers need it and that we don't have too much idle capacity that are increasing our fixed costs with that business. On the transceiver side, as I said before, the initial line is up in Thailand this quarter, so we'll be shipping samples, but we won't really get any volume shipments out of Thailand until the first calendar quarter of '25 when the qualifications that our customers have been done and the ramp up starts there, but we'll have growing capacity through calendar '25 and that's why we said about our confidence in achieving the $500 million per quarter by the end of 2025, calendar-wise.

Thanks, Alex. Did you have a follow-up question?

Yes, just to follow up on the telecom side, I'm a little surprised that the telecom component space is recovering in the September quarter, given the high level of capacities that are out at the customers, the OEMs. Can you talk a little bit about what product areas that you're seeing that in? And how fast do you think that the inventories are going to come down based on the demand you're seeing?

Yes, you're correct, Alex. There is still inventory among our customers and beyond. We've observed strength in products that we weren't shipping a year or two ago during the pandemic, which means there’s no inventory buildup for these products. The 130-gigabyte coherent components and the 200-gigabyte coherent components are just starting to be shipped. Additionally, our new ROADM products, which we weren't shipping a year ago, are experiencing strong demand in our integrated C+L as well as in new and differentiated high port count WSS. That's the situation we're encountering. We're witnessing strength in the narrow line with tunable lasers as the data center interconnect business has diminished a lot of the inventory, especially since people are placing data centers farther apart and can no longer connect them within a campus due to power requirements. So, generally, that's what we're seeing in terms of strengths in telecom.

Thank you, Alex.

Thank you. The next question is from Simon Leopold with Raymond James. Your line is now open.

Great. Thanks for taking the question. First one I wanted to ask is maybe if you could give us a little bit more color on the products associated with the new Datacom award. Specifically, I think these would be 800 gig and I'm guessing single mode products, but wondering whether or not there's more to it than a single product line, any color there? And as a follow-up, I also want to understand, on your telecom business in the June quarter, you had originally talked about a 30 million sequential decline. And so I'm trying to get a better understanding of did that occur? And when we think about the recovery and sequential growth in September, how close are we getting back to sort of the prior run rates before the June quarter? Thank you.

Yes, thank you, Simon. I don't want to discuss specific customers too much, but you're correct. Companies are not creating new products for outdated technology. We are very confident in our ability to develop, ship, and qualify the advanced 800 gig single-mode transceiver for this customer. Chris, do you want to address the telecom question? The revenue decline occurred in the June quarter for telecom. Your question was about telecom, right, Simon?

Yes, I wanted to understand sort of, you know, if you drop 30 and you go up five, well, that's still a big distance from where you used to be.

Yes, I don't know the specifics. I would say that, as we said, the telecom and Datacom business is up mostly from the telecom strength. And so, as we said before, the transition period for our Datacom transceiver business is happening Q4 and Q1, and we expect that to grow in Q4. So most of the growth in Datacom and telecom is coming from telecom bounce back from a really low point in the June quarter.

Thank you Simon.

Thank you. The next question is from George Notter with Jefferies. Your line is now open.

Hi, thanks very much. I'm just curious if you guys have an Nvidia qualification on this 800 gig single-mode transceiver?

We won't disclose who the customer is, but as I mentioned earlier, most of our customers are collaborating with us on products that they currently do not have. For example, we are developing 1.6 terabit transceivers, and their performance has been quite impressive. We intend to begin sampling these to customers this quarter, and there are a few key players that will be utilizing this technology. While you can draw your own conclusions from that, we won't provide details about any specific customer.

Got it, okay. And then, the transceiver customer, I guess I'm, based on something you said, I was curious about whether or not this contractor relationship is just a framework arrangement, or are there certain minimum volumes or minimum market share that you're being given by this customer? Anything you can say in terms of first source, second source, third source? I'd love any more details you can provide. Thanks.

Well, this is a new product, right? And so, it comes down to our ability to execute. And so, we will earn share, or earn more share, I should say, as we execute. And I think the combination of U.S. headquartered company, manufacturing in Thailand, there's certainly fear of what happens in the next election, and the tariffs impact the ability to be competitive when shipping out of China. So, I think we've got a lot of good things going in our favor, and then it'll come down to how well we execute the ramp. And I think we're very well-positioned to capture a significant amount of share there.

Thank you, George.

Thank you. The next question is from the line of Meta Marshall with Morgan Stanley. Your line is now open.

Great, thanks. Don't know if I'll get an answer here, but it's worth an ask. You've mentioned kind of the $500 million quarterly run rate exiting calendar '25, but just how should we think about kind of the Datacom capacity between chips and transceivers as you would have exiting fiscal '25? And then maybe just a second question there. Has anything changed with kind of the ramp patterns of kind of your lead customer today on transceivers and their design shift as we exit kind of calendar '24? Thanks.

Yes, I'd say, let me start with the chips adding capacity. We are adding capacity. We should see significant growth above market growth in our chip output over the next 12 months. And I think that's why we are, and we have more orders than that. So it's really constrained by our ability to add capacity, improve yields and then transition to 200 gig per lane chips. And so I would say that as the shift from 100 gig to 200 gig kicks in, there's a pickup in revenue per chip that we should experience as well. On the transceivers, as I said before, the monthly capital meetings where we determine how much capacity to put in place is what we're going through. And it's based on traction with customers and qualifications and awards and things like that. So we're certainly making sure we put the infrastructure in place, the facilities in place to support well over what I'm talking about for the $500 million per quarter in overall revenue. So I think it comes down to execution and our ability to win the mind share and market share for each customer we're working with. As far as the lead customer, I really don't want to talk specifics about customers, but I just reiterate what I had said before, which was product transitions happening in Q4 and Q1, and then we expect a pickup in revenue and Datacom in the December quarter.

Thanks, Meta.

Thank you. The next question is from Tom O'Malley with Barclays. Your line is open.

Hey, Alan, thanks for addressing my question. I wanted to clarify the new major transceiver award with the new customer. Can you explain the difference between an award, a win, and a qualification? I believe you mentioned that qualification would take place in Q1 and that it would be from the Thailand facility, which I understand won't be ready until calendar Q1. If the product is being qualified in Q1, could you discuss the timeline for its launch and how an award differs from a qualified product? It seems challenging to generate revenue from something until it’s actually qualified. Am I mistaken about the timeline I’m outlining?

Well, you're generally accurate. I'd say just a correction, our first production line in Thailand is operational this quarter, and we plan to build and ship product this quarter for the qualification. Now it takes them months to get the qualification work done. And so, it's not done until it's done, to your point, absolutely. Now we're staging material because we're confident in our ability to perform. We're staging capital to be able to support the volumes they're talking about. So I'd say from that perspective, it really gets down to us performing. Now, if the product doesn't work, they're not going to buy a product that doesn't work. And so you're right, we have to be qualified. We have to have quality and we have to have the ability to ramp. And we're making sure that we are controlling what we can control, which is the product quality, the design, the capacity, and the materials to support this customer who's critically important for us.

So I guess the follow-up is what would be different from an award versus the, yes, thank you, Kathy. Yes, what would be the difference between an award and what you're doing with other hyperscale or potential customers? Like, are you committing more capital to them? Because it sounds like if you're not qualified, isn't this just kind of R&D work on a potential future customer, which all other kind of development would kind of fall under?

Not really. I mean, each of these customers don't want to work with eight suppliers, right? So they have to down select to the ones that they're going to spend their engineering time with and they have chosen us. And so, we're not the only person for sure, but it's the choice that they've made and they've given us something that says, we're awarded the business, that we have to earn it and we have to perform as with anything that we develop for customers. So I'd say it's different than just working with the customer. I've chosen you out of the suppliers that I can choose. And again, for multiple reasons, proven technology, proven vertical integration, U.S. headquartered, outside of China manufacturing. So there's a lot of reasons that this customer chose us. And now we just have to perform out of Thailand, which is new to us, but I have confidence in the team to be able to execute.

Thank you, Tom.

Thank you. The next question is from Ruben Roy with Stifel. Your line is open.

Yes, thank you. Alan, I was wondering if you could comment a little bit on sort of how you're thinking about 1.6 terabit timing. 90 days ago, we talked about back after this year, perhaps into next year, but any changes on sort of timing of ramps? I think there's some dependence on switch availability and a limited number of customers potentially ramping in 2025. So any detail on how you're thinking about that would be helpful? Thank you.

Yes, I think our focus is really controlling what we can control, which is providing customer samples this quarter with high quality, high reliability, high performing 1.6T transceivers. And so we have multiple designs in the works that look very promising. And we're working hand in hand with, as you say, the few customers that would be interested in this today, because most are still working to get to 800 gigs. So that's our focus. When the customers need it, we will have it. And whether there's a switch soaking issue or other issues, we're not going to be shipping transceivers unless everything is ready to go. But that said, we want to be ready when they say go. And so that's why we're working on it now and have multiple designs, working with multiple customers to get that done.

Do you have a follow-up Ruben?

And a quick follow-up for Wajid. Yes, just a quick follow-up for Wajid on the gross margin comment. Just around thinking through record shipments of MLAs and sort of expectations for that ramp to continue into year-end, if you can give us any more detail on how you're thinking about the gross margin progression as you get into fiscal '25?

Yes, thanks, Ruben. Yes, so as we mentioned in our prepared remarks, both the benefit of an improved telecom outlook giving us better manufacturing utilization across our multiple factories is certainly giving us a tailwind on gross margins moving into the new fiscal year. Along with that, the record Datacom shipments that Alan talked about fulfilling that backlog are going to also give us a tailwind given that it's chip business, as you know. And then the transition over into 200G EMLs being a larger part of that mix will also provide a tailwind for us. So that'll progress through the quarters as those shipments happen.

Thank you.

Thank you. The next question is from Vivek Arya with Bank of America. Your line is now open.

Thanks for taking my question. So Alan, in the path towards getting to $500 million, what does your telco business need to be as part of that $500 million, i.e. what assumptions are you making for the recovery in telco to get to that landmark by the end of next calendar year?

We don't require significant growth in telecom. We're not relying on that. We're seeing a return to pandemic levels, which I believe were inflated shipments. We're certainly above where we were in the June quarter, as I think that represented the low point for us regarding telecom shipments. We anticipate some improvement throughout 2025, but not substantial growth in telecom. Most of the growth is expected to come from EML chips, the transition to 200 gig, and optical switching in datacom, which should begin to ramp up by 2025, along with one or two transceiver victories. This is essentially all we need to reach $500 million.

All right. My follow-up on the transceiver side, how substitutable do you think our products from the different suppliers? Like how do you think the customer will allocate share, right? What's going to be the level of visibility that are your products better suited for some specific accelerator or switch combination? How would you know what your share is? How would you know what your share could be potentially next year?

Yes, I believe it ultimately depends on our performance and supply security. We are focusing on manufacturing outside of China, and many of our partners who purchase our chips are also relocating. However, we have a significant presence in China with thousands of employees and skilled engineers. Our operations in Thailand are well-established, allowing us to produce high-quality products and increase our market share. The main question is how much we will capture, and our goal is to earn a substantial amount. We need to ensure we provide what our customers require, on time, with sufficient capacity, materials, personnel, and engineers to deliver high-quality products and gain their business. There is also the need for interoperability, and we must collaborate with various switch providers to ensure this. Fortunately, the specifications are generally consistent and straightforward, so we understand what we need to do to achieve seamless integration.

Thanks, Vivek.

Thank you. The next question is from Karl Ackerman with BMP Paribas. You may proceed.

Yes, thank you. First off, I guess, could you discuss why you are stopping in-house development of coherent DSPs? Is that related to limited uptake for 100 gig coherent in the access market or are there other factors to consider? As you address that question, are you seeing any pause in coherent optics demand broadly, at least for DCI applications? Thank you.

Yes, I'd say that we have a fixed amount of R&D we can spend and we're shifting to where we can make a big difference into markets that are growing faster. And so the combination of that, so we're adding more to the Datacom transceiver business, combination of that and the partnering with third parties, both from our customers as well as from third-party independent chip manufacturers allows us that ability to get what we think we need to get at an overall cost of ownership that's less than developing a three-nanometer DSP. So from that perspective, I have confidence in our ability to secure DSPs at competitive prices, to be able to address the data center interconnect market. But that said, we believe, I believe that pivoting from spending on DSPs to spending on higher growth markets like inside the data center will pay off and pay dividends.

Do you have a follow-up, Carl? Okay, operator, can we take our next question, please?

Absolutely. The next question is from Ananda Baruah with Loop Capital. Your line is now open.

Yes, thanks guys. Congrats on the progress. Thanks for taking the question. I just have just one here, and they may be false as a clarification category, but Alan, with the new win and the way that you're talking about doing some shipping this quarter, are you guys tracking ahead on the data center qual sort of dynamic that you began to talk about, I think back in LSC? I guess just as I recall it, it was mostly quals were going to take place kind of around the beginning of the year. And I know, as Tom talked about, there's some language here, but so let me just ask it that way. Are you tracking ahead of some of the qual activity? That'd be helpful. Thanks a lot, guys.

Yes. Thanks, Ananda. I'd say we're tracking right on schedule. We had to finish out a clean room. We've done that in our timeline facility. We've now equipped it. We're ready to start building qualification units, and so that's right on track. And as you say, the qualification won't be done until late this calendar year. It will allow us to ramp production into the January timeframe. So that's right on track for what at least our internal plan has been and what I thought we had discussed at OFC earlier this year.

Okay, great. Thank you. Joe, could we have our next question, please?

Thank you. The next question is from Tim Savageaux with Northland Capital Markets. Your line is now open.

Hey, good afternoon. I want to focus back on capacity from a couple of different perspectives. Maybe relative to what you've got now, you mentioned you're at capacity in indium phosphide or EMLs. Can you quantify the extent of the planned capacity addition there over, I don't know, the next year? Are you doubling, tripling capacity, what have you? And really same question relative to your current run rate on the module side. I think that was expected to come down this quarter with the product transition. What sort of capacity are you looking to add in Thailand relative to that, and it sounds like it's a fluid situation, but over what timeframe, I guess?

Sure. The situation with chips is straightforward because the equipment needs to be in place now for it to have a significant impact this fiscal year. However, we are aiming to increase our capacity quicker than the market's growth, which is projected to be 30 to 40% this year. It's not about doubling our efforts, as that would require extensive resources and could distract our team—it's simply not practical. On the chip side, we can expect an increase of over 40% from the June quarter to next June quarter. Regarding transceivers, we are currently below our levels from the March quarter, but we are adding capacity as opportunities arise. We have ensured that the construction of clean room shells is completed, which is a less expensive initial step. This will allow us to install equipment much more quickly. With our initial success, we are setting up capacity that will be operational by the end of this year, ready to ramp production early next year. While I can't specify an exact dollar amount increase, I can say that for transceivers, we are positioned to exceed two to three times our previous output in the coming 12 months.

Got it. Yes. Understood. And for a quick follow-up, would that capacity in Thailand be entirely incremental? Or are you moving capacity over from China effectively, or shutting that down at all? Are you maintaining that as a base? And I'll leave it there. I don't want to get greedy here.

Yes, that's a good question. I'd say that initially it's incremental because customers don't want us to move existing products, but as we bring on new products, we'll be ramping them more up outside of China than adding more capacity inside of China. So that over time, over the next couple of years, there'll be a transition to mainly in Thailand, or I should say outside of China, because that's what our customers want. And I think having a center of excellence in Thailand gives us that capability to move capacity and add capacity in Thailand with our workforce that we've got there.

Thanks, Tim. Joel, I'd like to be able to squeeze in one more question if we could.

Absolutely. The next question is from Richard Shannon with Craig-Hallum. Your line's now open.

Great, guys. Thanks for taking my question. I think I'm going to spend most of my questions on one multi-part here. Some of the topics were asked earlier about how to think about your path from current guidance revenues to the $500 million plus level ending next calendar year. And your response to that question was pretty interesting in a number of ways, Alan. Maybe I'll broach two or three of them here, where you said you didn't need much telecom to get there. Expecting most of it from EML chips, also transition 200-gig EMLs, Datacom optical switching, and some transceiver stuff here. I'm not sure if that last part was intended to be in like ascending or descending order of contribution, but maybe a comment on that, that would be great. And I guess specifically, I'm quite interested in two aspects of this, one of which is the optical switching, is that expected to be a meaningful contributor to this growth to get to 500 million? And then also, are you not expecting much from telecom, or is that just upside if you get it? Thank you.

That is a multi-part question. I'm happy I noted it down. Thanks, Richard. I would say there was no specific order in my list of priorities. If I had to rank them, I would say transceivers are the top growth area. Optical switching is likely to be more significant in 2026 than in 2025, and while I wouldn't say it's less meaningful because we anticipate notable revenue in 2025, it's really positioning us for substantial growth in 2026 regarding optical switching within the data center. I've already mentioned that EMLs are expected to grow by over 40% in the next 12 months. I've been hoping for telecom to rebound over the past year, but I’m no longer relying on that, although we are currently seeing some short-term growth. I believe we don’t need to return to the pandemic levels, and that expectation is not factored into our projection of $500 million per quarter. So, it really comes down to executing effectively on transceivers, awards, EMLs, and transitioning to 200 gig, where the revenue per unit exceeds that of the 100 gig. I hope that answers your question.

And that added quite a bit to it, Alan. Thank you very much. That's all for me.

Okay, great. Thanks, Richard.

So with that, I think we're going to wrap the Q&A portion of the call. And I'll pass the call back over to Alan for some concluding remarks.

Thanks, Kathy. And thank you, everyone. I'd like to just leave you with a few thoughts as we wrap up the call. Our agility and photonic leadership position equip us to navigate current market challenges and opportunities. Momentum is at the forefront of the data center revolution, driving chip scale photonics, automated manufacturing and hyperscale cloud partnerships. We are rapidly scaling manufacturing and R&D to capitalize on cloud opportunities and meet surging data rate demands. As we discussed in prior quarters, the Cloud Light acquisition is accelerating our high-speed transceiver qualifications and production positioning us for multi-billion dollar cloud revenue and over $500 million quarterly revenue by the end of calendar 2025. Thank you all for joining our call today. We look forward to seeing you again at investor conferences and upcoming meetings this quarter. Have a great day.

That concludes today's conference call. Thank you for your participation. You may now disconnect your lines.
