Lumentum delivered a standout second quarter with over 65% year-over-year revenue growth and non-GAAP operating margin increasing by greater than 1,700 basis points. At $665.5 million, we set a company record for quarterly revenue for the second reporting period in a row. We are now recognized as a foundational engine of the AI revolution. Virtually every AI network is powered by Lumentum technology, either through our direct hyperscaler partnerships or as the critical component supplier that enables our network, equipment, manufacturer, customers. Our momentum is accelerating. While we previously projected crossing $750 million in quarterly revenue by mid-2026, we now expect to comfortably surpass that milestone next quarter. Our March revenue guidance, with an $805 million midpoint, represents an impressive 85-plus percent year-over-year increase. We previously identified three primary catalysts for Lumentum's future growth. Cloud transceivers, optical circuit switches, or OCS, and co-packaged optics, or CPO. The headline for this quarter is that the vast majority of this growth is still ahead of us, and we've increased confidence as to the timing and magnitude of the ramps. While our Q2 results and Q3 guidance reflect meaningful contributions from cloud transceivers, we are only just beginning to unlock the massive potential of OCS and CPO. Beyond these high-growth drivers, our Q2 performance was anchored by sustained execution on a foundational components business, specifically in laser chips for cloud applications and in specialized components for DCI. I will now break down our Q2 performance, starting with execution in our primary growth drivers. Our OCS business is exceeding internal expectations. While we originally targeted our first $10 million quarter for fiscal Q3, we cleared that bar three months ahead of schedule. This outperformance is a direct result of the seamless collaboration between our engineering and operations teams, proving our ability to scale complex technology at pace. Customer demand for OCS is intensifying. Our order backlog now has surged well past $400 million, the majority of which is slated for shipment in the second half of this calendar year. Barring any unforeseen manufacturing or supply chain disruptions, we are well positioned to deliver on this substantial pipeline. Our execution in cloud transceivers has reached a definitive turning point. In Q2, transceiver revenue grew significantly and outperformed the legacy cloud-like run rate, and we expect continued growth in Q3. We have focused on time to market in the business and have greatly improved our execution through the design cycle. As a result, we are now in the lead pack of transceiver suppliers as customers transition their networks to 1.6 T speeds. Beyond design execution, we are also improving the profitability of our transceiver business with better yields and lower scrap rates. Turning to CPO, we have secured an additional multi-hundred million dollar purchase order for ultra-high power lasers that support optical scale-out applications. We expect shipments for this incremental order in the first half of calendar 2027. Meanwhile, we continue to execute on the initial orders we have discussed previously and remain firmly on track for material shipment inflection of UHP chips in the second half of this calendar year. Furthermore, we have established a clear line of sight into the broader external light source, or ELS, market, which would enable us to participate more holistically than as a standalone laser chip supplier. By expanding into pluggable external-length source modules, we would dramatically increase our serviceable market. In addition, the ELS allows us to diversify our customer base as several new partners adopting next-generation scale-out architectures are looking for more turnkey solutions. We have built significant momentum through our leadership in CrowdTransceiver, OCS, and ScaleOut CPO. Now, a fourth growth driver is taking shape, one poised to be a generational game-changer for the industry, optical scale-up. Today, data center architectures have a clear divide. Optical links handle scale-out networking, connecting relatively longer links within the data center. Conversely, copper links dominate scale-up connectivity, referring to the ultra-short-reach, high-speed pass within a single rack or a cluster. While copper has long been the gold standard for scale-up for simplicity and cost, it is hitting a physical wall. An industry pivot is underway to bypass the scaling limits of copper. By late calendar 2027, we would expect our first scale-up CPO shipments, replacing longer copper connections. We are already deeply embedded in design-in cycles for this, leveraging our ultra-high-power lasers and external light source modules. As we look into the not-so-distant future, it is only right to assume that optics begins to capture more and more of the connectivity, eventually subsuming copper. In response to these demand projections, we've initiated proactive capacity planning. Given the sheer magnitude of the scale-up optics market, we are carefully assessing our projected wafer output plans. We are in active negotiations with leading customers to offset our capital requirements in exchange for long-term supply assurances. These discussions underscore the critical nature of our technology and their roadmaps. Now, let's look closer at the key performance metrics that defined our second quarter. In our last earnings call, we introduced two primary product categories. Components, the foundational building block for larger solutions, and systems, which are standalone products providing full functionality, such as optical transceivers, optical circuit switches, and industrial lasers. Components revenue for the quarter reached $444 million, representing a 17% sequential increase and 68% year-over-year growth. This performance was fueled by broad-based demand across laser chips, laser assemblies, and inline subsystems going primarily into inter-data center, DCI, and long-haul applications. Our laser chip business, serving cloud transceiver customers, drove outsized sequential growth this quarter. We achieved another quarterly company record in EML laser shipments, led by 100-gig lane speeds, and bolstered by a ramp and 200-gig devices. Simultaneously, we expanded our footprint in next-generation architectures, shipping CW lasers for 800-gig manufacturers and increased volumes of ultra-high-powered laser shipments for CPO applications. Our indium phosphide wafer fab capacity remains at a premium, fully allocated to meet surging customer demand. We have front-loaded our 40% expansion target, delivering on over half of that this past quarter. We are scaling rapidly through precision tool optimization and yield gains. This execution will help to ensure that additional capacity comes online as planned over the next two quarters and beyond. While not able to size it, we now have line of sight to a significant block of additional capacity, starting in the second half of 2026, both through current activities in Sagamahara and better utilization of our Caswell, United Kingdom, and Takao, Japan, FAPS. Beyond sheer volume, our Q2 revenue was propelled by a favorable mix shift toward 200 gig lane speeds, which provide a meaningful ASP uplift. While these high-speed devices represented approximately 5% of unit volume, they contributed roughly 10% of data center laser chip revenue. Moving to our scale across business, we continue to see sustained momentum in components supporting optical links ranging from intercampus to longer reach topologies. Shipments of our narrow line width laser assemblies grew for the eighth consecutive quarter, a clear proof point of robust market demand and our successful manufacturing expansion. Our long-haul portfolio also saw gains, with both coherent components and aligned subsystem products growing sequentially and year-over-year. In addition, we achieved another record quarter for our pump lasers, supporting not only long-haul terrestrial and subsea networks, but also new scale-across architectures, with revenue in this product line surging over 90% compared to the prior year. Finally, 3D sensing grew modestly following a new smartphone launch and some incremental share gains. In systems, revenue reached $222 million, representing a significant 43% sequential and 60% year-over-year increase. Cloud transceivers accounted for the lion's share of this growth, increasing by approximately $50 million on quarter as we successfully leveraged our expanded manufacturing capacity in Thailand. As noted last quarter, we have moved past the production volatility seen in earlier calendar 2025 and are now on a sustainable growth trajectory. Our Q3 guidance reflects this momentum as we begin to see the revenue layering benefits typically enjoyed by larger transceiver makers. as noted earlier optical circuit switches continue to grow and we're the good news story of the last quarter on the other hand as our cloud related business continues to accelerate we see a different dynamic in the industrial end market here shipments remain roughly flat sequentially in q2 this performance reflects the persistent cyclical softness we continue to see in the broader industrial market. With that said, we have an increasing design wind funnel for our newly introduced PicoBlade Compact line of products. Looking ahead to Q3, we expect to achieve a new quarterly revenue record with our guidance midpoint exceeding historical revenue levels by a substantial margin. Within this outlook, we anticipate that approximately two-thirds of the sequential increase in revenue will be driven by our components portfolio, reflecting broad-based strength across cloud applications. The remaining one-third will stem from systems, fueled by the continued ramp of high-speed transceivers and additional contributions from OCS. In summary, Lumentum has established itself as a market leader in transformative optical technologies. Our position across OCS, optical scale-out, and optical scale-up is the envy of the industry. Furthermore, we are now meaningfully participating in the well-documented growth in the optical transceiver market. With all that said, we continue to believe that our current performance is only a precursor of things to come. Now we'll hand the call over to Wajid.

Thank you, Michael. Second quarter revenue of $665.5 million was at the high end of our guidance, and a non-GAAP EPS of $1.67 was well above our prior expectations, demonstrating the leverage of our business model. Gap gross margin for the second quarter was 36.1%. Gap operating margin was 9.7%. Gap net income was $78.2 million. And gap net income per share was $0.89. Turning to our non-gap results, second quarter gross margin was 42.5%, which was up 310 basis points sequentially and up 1,020 basis points year-on-year. Due to better manufacturing utilization across the majority of our product lines, increased pricing on select products and favorable product mix. Mix improvement was primarily driven by our ramp and data center laser chips. Second quarter non-GAAP operating margin was 25.2%, which was up 650 basis points sequentially and up 1,730 basis points year-on-year, primarily driven by revenue growth and components products. While continuing to invest in critical R&D programs serving cloud and AI customers, we have maintained the rigorous cost controls necessary to optimize our business model. Second quarter non-GAAP operating profit was $167.7 million and adjusted EBITDA was $198.3 million. Second quarter non-GAAP operating expenses totaled $114.9 million or 17.3% of revenue, an increase of $4.4 million from the first quarter and an increase of $16.6 million from the same quarter last year in order to support our expanding cloud opportunities. Q2 non-GAAP SG&A expense was $45 million. Non-GAAP R&D expense was $69.9 million. Interest and other income was $4.6 million on a non-GAAP basis. Second quarter non-GAAP net income was $143.9 million, and non-GAAP net income per share was $1.67. Our diluted weighted shares for the second quarter was $86.1 million on a non-GAAP basis. Turning to the balance sheet, during the second quarter, our cash and short-term investments increased by $33 million to $1.16 billion. Our inventory levels increased by $39 million dollars sequentially to support the expected growth in our cloud and AI revenue. In Q2, we spent $84 million in CapEx, primarily focused on manufacturing capacity to support cloud and AI customers. Turning to revenue details, components revenue was $443.7 million, dollars, which increased 17% sequentially in Q2 and 68% year-on-year. Systems revenue of $221.8 million increased 43% sequentially in Q2 and 60% year-on-year. Now let me move to our guidance for the third quarter of fiscal year 26, which is on a non-GAAP basis and is based on our assumptions as of today. We anticipate net revenue for the third quarter of fiscal year 26 to be in the range of $780 to $830 million. The $805 million midpoint would represent another new all-time quarterly revenue record for Leventon. We project third quarter non-GAAP operating margin to be in the range of 30% to 31% and diluted net income per share to be in the range of $2.15 to $2.35. Our non-GAAP EPS guidance is based on a non-GAAP annual effective tax rate of 16.5%. These projections also assume shares used for non-GAAP diluted earnings of approximately 92 million shares. With that, I'll turn the call back to Kathy to start the Q&A session. Kathy?

Thank you, Ajit. To allow as many people as possible an opportunity to ask questions, please keep to one question and one follow-up. Kevin, let's now begin the Q&A session.

We will now begin the question and answer session. A reminder that if you would like to ask a question, please raise your hand. If you have dialed in to today's call, please press star nine to raise your hand and star six to unmute. Please stand by as we compile the Q&A roster. And your first question comes from the line of Simon Leopold with Raymond James. Your line is open. Please go ahead.

Great. Thank you for taking the question. Hopefully you can hear me OK.

Yeah, we can hear you, Simon. Yeah.

Yay, I can work Zoom. So I just wanted to see if you could maybe double click on the OCS market, which sounds quite a bit better than what you discussed last quarter. So maybe if we could hear a little bit more color in terms of how you're seeing the market, the exit rate, and the customer diversifications. And I'll give you my follow up because it's relatively quick in that you've raised prices. Is there any way you can help us quantify what impact your price increases have had on the growth? Thank you.

Yeah, hey, Simon. Yeah, the OCS market is definitely developing a lot better than we believed. It's accelerated, certainly from a time standpoint. So the data point we gave today is that our backlog has increased to well in excess of $400 million, most of which is going to be shipped in the first two quarters of fiscal 2027. So we're really going to exit the calendar year on quite an increased velocity. If you remember, you and I discussed last time, we believed our Q4, the calendar Q4, would be around $100 million. It looks like it'll be quite a bit higher than that, although we're not breaking up that $400 between the two quarters. So it's a broad-based. There's multiple customers making up that backlog. You know, we've talked about shipping to three customers, and that continues, but those customers are increasing their demands rather significantly, and thus, the demand on us has gone up quite appreciably. So, we feel pretty good about that. I think as we enter calendar year 2027, you know, it should go up from there in terms of what we see in our backlog and in terms of our revenue. On the second question, obviously, price increases are definitely having an impact both on top line and gross margin. They are starting to flow through in the Q1 or the March guide, where we're seeing a lot more of that. As we said last quarter to you and to others, we'd expect a little bit of impact in the December quarter, and we've had a little bit, but not a lot. We see a little bit more in March. I don't know if we've quantified how much of it is. I think it's relatively modest, you know, in terms of the overall revenue impact. Margin, certainly a little bit more. But, you know, we're doing a lot of things to benefit margin, including cost down, a lot of work on manufacturing scrap and yield. There's just been a lot of intense focus from myself, Wupen, Widehead on the gross margin line. So a lot of things are contributing to that. And, you know, for the first time, we're moving up into the 40s.

Thank you, Simon.

And your next question comes from the line of Samik Chatterjee with J.P. Morgan. Your line is open. Please go ahead.

Thank you. Thanks for taking my questions. Michael, Wajit, Kathi, good to speak to you. Maybe I'll start off on the Indian phosphide capacity ramp. And just to clarify what you said in your prepared remarks, you pulled forward or front-end loaded some of that capacity increase that you had planned, And we're going to see the effect of that in the March quarter guide just to confirm that. And then what does it mean for the end state in terms of the sort of 40, 50 percent capacity increase that you had planned? Does that change the end state in terms of how much capacity you can add to those existing FABs? And as you're talking about alternatives with your customers, does it really sort of focus on the existing FAB or are you assessing sort of new FABs? And then a quick follow-up. Thank you.

Yeah, Sonic. Look, we're definitely doing better than expected. I think that we characterized in the last call that we'd see a 40% impact from our September quarter over the next three, so December, March, and June. What we're saying here is that we probably got somewhere a little north of 20% in the December quarter alone. So in the results in the December quarter, in the guide, we're not necessarily saying how much of the increase is there. There's obviously more. I would expect at this point that given that we see kind of half of the impact in the first of the three periods that we'd outlined, that we were going to do a little bit better than 40%, but we haven't quantified that. What we are saying is now we have line of sight to more capacity increases through the next four quarters, meaning probably the second half of 2026, calendar 2026, into early 2027, by virtue of the improvements that we continue to see in Sagamara. So 40% is all Sagamara. But we would now start to see some impact from our Caswell facility in the United Kingdom and also contributions from our second fab in Japan to Cal. So all of these things together say that we have line of sight to do a little bit better than we outlined on the last call and certainly extend the ramp more appreciably than perhaps we said on the last call.

Got it. And Michael, I mean, just following up on that, any new fabs being considered when you're sort of talking to your customers? And then for my second question on transceivers, I mean, you took a sizable step up here in the December quarter. I think you're taking another bit of a step up into March. You had previously indicated you sort of want to maybe manage that business to $250 million a quarter run rate. I mean, is that still sort of how you're thinking about it or because most of the demand is from one customer, you sort of can scale further than that? Any updated thoughts on that? Thank you.

Yeah, I mean, on the transceiver question, I do think that it's going to be more difficult than we outlined in the last call to sort of cap that to a billion dollars. We're definitely seeing a lot, a lot of demand for our transceiver products, not only from the primary customer, but from other customers as well. So suddenly, you know, as I said, we've turned a bit of a corner. Wupen is here, and I think he's done a super job with the transceiver business, improving margins, improving executions, primarily improving our design time, our time to sample. and as I said we've actually got into the front of the pack as a result of that so I feel a lot better about the transceiver business that being said still a margin headwind right so no change from where we are before a little bit less of a margin headwind because we made these improvements but still a margin headwind I think however it will be a challenge we are seeing appreciable growth growth in the demand of our transceiver products, Wajid is here. I think we can manage the portfolio to increasing gross margins and increasing operating margins in the face of a business that might be greater than a billion dollars. Am I wrong? Yeah, no, that's fair. I mean, I think

when we made the comments about $250 million a quarter or a billion dollars that Michael alluded to, our thinking on the rest of the business probably wasn't as large as how we're thinking about it today. Certainly, OCS, CPO, the multi-hundred million dollar order that Michael talked about in his prepared remarks, all of those things are contributing to a larger pie for Lamentum. And so as part of our operating margin profile is revenues grow. So, you know, the fact that the rest of the business is growing faster than we expected allows us to grow the transceiver business. And then, you know, because 1.6T margins are significantly better than 800G, that's also helping us, you know, say yes to more orders that are coming in. And Michael's right, they're coming in substantially higher than we had expected. Kathy, what was Samick's first part

of a question. New fabs. Okay. Yeah, Samik, I mean, to that question, yes, that is an active investigation. We're certainly looking at how we can bring on more capacity, whether it be creatively in the current fabs that we have or bringing on new fab capacity by acquisition or something of that nature. So it's an active discussion in the company. Nothing to talk about at this particular point, but it is certainly something that's top of mind for us. Thank you. Thanks for taking my

questions. Thanks, Samik. And your next question comes from Ryan Coots of Needham & Co. Your line

is open. Please go ahead. Great. Thank you. I want to double click on the transceiver market, if we could, and the transition to 1.6T. Obviously, some great progress at 800 here. is that primarily being driven by emails today how do you see the readiness of sifo at 1.6 t being prepared and and then what are your kind of derivative uh you know laser supplier opportunities how are they stacking up overall for the 1.6 t transition thank you yeah right

let me talk a little bit to the um the the laser part of the market and then maybe throw the ball to whoopan because it's two separate things and certainly for our business the transceivers as we've characterized a couple of times our transceivers are mostly silicon photonics but what we're seeing right now from our customers is a strong eml demand most of the initial transceivers that are going to 1.6t are based on emls and that's good um our 200 gig lane speed as as we said, is actually doing a little bit better than we expected. I think in the last call, we had said that the 5% revenue, 5% of mix would be this quarter. It was a quarter earlier than we'd expected. And that's primarily because 1.6T isn't coming on, I think, faster than we initially anticipated. And that is heavily being driven by 200 gig EMLs. That being said, I still think, you know, Consistent with what we've said over the past, we would expect silicon photonics to be the majority of the transceiver shipments at the 1.6T node. We think the numbers are so large, based on what we're seeing in terms of the demand from our customers, that our EML shipments, even in the face of a mixed shift toward silicon photonics, the absolute number of EMLs will go up for us, and rather appreciably. So we feel really, really good about the way the market is shaping up. Our lead on EMLs is second to none. We're introducing 200 gig differential EMLs now to give us another leg up in that market. So we feel pretty good about the way that's setting up. Wu-Pen, on the transceiver side, you want to talk about our transceivers and how we're thinking about 1.16?

Yeah, thanks, Michael. So, you know, on the trans-C1.6T products, there are still really, by and large, two groups of applications. One group requires WDM-based solutions. One group requires basically a parallel fiber-based solutions. And therefore, you will see that EML is pretty dominant in the WDM-based architectures. And then the signal photonic starting to take more share on the kind of parallel fiber applications. We see these kind of hand-in-hand grow at a similar pace, and that's why Michael was talking about EML will continue to grow, despite the fact single photonics will take a more share in 1.60 generation. Overall, as what you talk about, we see 1.60 generation of products having a higher gross margin at the marginal level, and then, of course, we'll benefit continuously on the laser front in this generation as well.

right any update on your plans on you know uh vertically integrating your own your own cw lasers

at 1.6 t is that still still the plan still the plan yeah we we had shipped uh you know cw lasers to the external market for the first time ryan uh last quarter uh those shipments continue to sort of help us develop and improve our cw laser technology i would say our timeline is pushed out a bit. In terms of that introduction, we were talking about introducing that our own CW lasers and our own transceivers kind of Q2-ish. And I think it's probably pushed out to late Q2, early Q3. It's probably been a two to three month push out relative to that introduction, but still very much part of the plan to continue to increase the gross margin in our transceiver business.

Right. Thanks. And maybe just a quick follow up on the laser opportunity in CPO. Do you view that competitive landscape any different than you view the transceiver laser market? Are there nuances there that investors should be aware of relative to bigger barriers to entry or your capabilities relative to the overall market for CPO?

I mean, look, I think on CPO, we feel really good about our position. I mean, certainly for EMLs, we also feel very good about our position, but I think we feel even better about our position on high-powered lasers going into CPO. Remember, a couple of things, right? One, the power level that needs to be delivered here, 400 milliwatts, is not something that many people can do. But perhaps more importantly, remember, you and I have talked about this, that technology has been proven out in our subsea applications. One of the big issues with CPO has always been reliability. And I think now we've gained real customer confidence. I mean, it is much more broad-based, I think, than people think in terms of customer engagement now on CPO, and that is primarily driven by the reliability that we're able to prove out.

Terrific. Thanks for the commentary.

Thanks, Ryan. Good question.

Thanks, Ryan.

And your next question comes from Vijay Rakesh of Bank of America. Your line is open. Please go ahead.

Yeah, hi. Thanks, Michael, Wajid, and Kathy. This is Vijay from Mizuho. Congratulations on a great, fantastic set of numbers here. Just a quick question. I know you're on CPO. You mentioned another multi-million, multi-hundred million dollar order there, and also your own CPO ramping well. Can you size what the CPO quarterly run rate would be with the new multi-million dollar, multi-hundred million dollar order? And also, I believe, CPO for scale up, as you mentioned.

Yeah, I mean, what we're talking about now is mostly scale out, right? So what we've said in the past is that we would expect somewhere around $50 million in the fourth calendar quarter, perhaps more, but we're kind of pegging it there. And then this multi-hundred million dollar order, while we're not prepared to give the size, really is clicking in in the first half of 2027. So it kind of gives you a rough feel. This is definitely ramping. It's ramping across not just one customer, multiple customers. The strain on our fab is high, right? We're very much sold out in our high-powered laser fab. And this is one of actually Wupen's primary tasks is to figure out how we can bring more capacity online much more quickly. I mean, this ramp is hitting us probably faster than we forecast even last quarter. So we have a lot of confidence in the ramp. We have a lot of confidence in the demand and backlog that we see. Now it's going to be really a matter of servicing that.

Got it. And then on the indium phosphide side, I know you said a lot of the capacity is sold out. You're adding some 40% capacity, more front-end loaded. But as you look through into 26-27, given this very strong ramp on EML, Neutroner GML, and also what you're seeing on the transceiver side, would you expect pricing to be a tailwind through most of this year and into next year too? Thanks.

Yeah, I mean, look, we really are sold out. I mean, I think that we've talked about sort of trailing demand. Even as we add capacity, it seems that the demand supply imbalance increases. We talked about that last quarter, and I'd say again, even as we've added this 20% additional capacity, the demand supply imbalance has increased. And, you know, I'm going to have Wu Penn comment. I think his team is spending a tremendous amount of time trying to squeeze product into our allocation bucket. It's really like a jigsaw puzzle for these guys to figure it out. The good news for us is that we'd expect now to increase supply throughout the calendar year. We've obviously sort of indicated that we have another 20 percent to go over the next couple of quarters. That probably is going to come up a bit, just given our current trajectory. And now what we're saying is we have line of sight for additional capacity in the last two quarters of the calendar year. In that, we obviously have this mix issue where our 200 gig lasers are a big portion of the mix. Today, small, 5%. We've said that by the end of the calendar year, we'd expect to be 25% of our mix to be 200 gig. And you can see in the prepared remarks, roughly two to one on the pricing. So our ASP will increase, margins will increase in that balance as we get more and more 200 gig. The really good news first story for us, I think, is the differential 200 gigs, which offer significant price power reductions for customers. that is yet another tailwind on ASP that we'd expect to see and another big, big enhancer on gross margin. Wupen, I mean, how are you thinking about it?

Yeah, thanks, Michael. So, yeah, in addition to what Michael described, right, in terms of capacity increase, and I think our team continue to really drive the yield up and reduce the die size of the chips, for example. Definitely, we're trying to squeeze every bit of the capacity output that we can get from our current fans. um as michael already pointed out um the the demand supply imbalance continued to uh to uh increase and therefore we're doing everything we can uh trying to grow that uh supply base um and then continue to to drive the uh the yoda so all very good but very challenging uh we look forward to serving the market with better better chips and more chips got it thanks fantastic

Thanks, Michael, Wajid, Wupan, and Kathy.

Thank you, Vijay. Good speaking.

And your next question comes from Papasila of Citi. Your line is open. Please go ahead.

Thank you for taking my questions and congrats on the impressive result. So, Michael, I guess for my first question, it is on visibility. I'm curious if you continue to see further visibility from your key AI customers on the EML front. I think previously you quantified for us that the supply-demand gap has moved from 20% to 25% to 30%. Has that gap extended? And tied to that, it would be helpful to understand how has your longer-term contract or commitment with customers changed now versus one to two years ago? So our new commitment, for instance, kind of longer in duration? Are we able to add more pricing versus before just any color?

Yeah, Papa, look, first, I want to thank you for some of the insightful notes you've written over the last last couple of weeks. We certainly appreciate the diligence you're doing on the business. You know, number one, obviously, the supply and balance, supply demand and balance is still very much there. I would say that it's about the same this quarter as last quarter, even in the face of adding the 20 percent and what we anticipate in the March guide. If anything, it's incrementally up, but I'd still say it's roughly 25 to 30 percent off. We're 30. We're under shipping our customers demand by somewhere around 30 percent. It's a it's a relatively big gap. And again, tremendous pressure, you know, on on Wupen's team. With respect to the long term agreements, I mean, frankly, and I'll have Wajid comment, the company never had these long term agreements. I mean, it was a very tactical business until, you know, Wajid and I got involved in the business and started seeing that there was a lot of opportunity to institute these long term agreements. All of our capacity, just to be very clear, on EML is spoken for in these LTAs. We have very tight LTAs that run through the balance of calendar 2027. And even as we increase the capacity, everything is spoken for. So we've projected out what we can do. Look, if we do better in capacity, we might have a little more to sell. But that is really spoken for. we're really proud of the LTAs that we were able to get in place and look, our customers are very happy we do have pricing leeway in there, I mean, I think as conditions change YG, BluePen, and I will continue to look at the pricing as you know, we've done a couple of step ups and our products are just in high demand right across the board so I think it gives us some pricing latitude and we'll certainly look at that. I mean, Wajit, any comments from you on the LTAs? No, I mean, I think you've captured it.

Actually, the whole LTA process has actually helped us from a pricing standpoint overall because then there aren't those same type of quarterly negotiations for price downs. If anything, prices are holding or they're increasing for what customers want. And what we're actually seeing is that customers are coming back and asking for even more capacity and more product than we had agreed to in the LTA. And that's actually allowing us to have incremental pricing discussions around those incremental units that they're asking for. So the LTAs are serving as a nice baseline. And if customers want more than that, then it allows for a discussion with Wupen's team and our sales team to ask for incremental pricing optimization. So it's worked out very well for us from a process standpoint. And for those customers that are not willing to sign an LTA, are having concerns about their continuity of supply, because we are allocating to those partners that are committing to us first, and then whatever's left over, then we can talk to those that are not.

Got it. Thank you. That's very helpful. And thank you, Michael, for the feedback. Just quickly on the follow-up, and apologies if it's a little bit of a long-winded type of question, but I just wanted to double down on the CPO opportunity, particularly if we contrast it with the opportunity you have on the EML slash transceiver front. I think previously you discussed in terms of content per accelerator or content per AI server, the two opportunities are mostly on par, and you really benefit from having a higher market share on the CPO side versus the transceiver front. Now that I guess you have more sales or you have more visibility, any change on how you are thinking about content for CPO versus the transceiver business?

Yeah, I mean, it's exactly as you said. I mean, obviously, the dollars are lower for our lasers than they would be if we were able to sell a transceiver. But given the strength of our product in the laser product, we have quite high market share. So in general, and Kathy's run the numbers for us a number of times, the math works out very favorably for us as CPO comes online. What I'll say, and I want to highlight again what we said in our prepared remarks, which is new, there is an opportunity for us to participate now in something that looks like a module, this ELS, the external light source. And that is obviously a much higher ASP. Wupen and team are looking at that now. It looks like we can preserve very decent margins and attack that market at another step up in terms of ASP. It's somewhere around two, two and a half times content gain from a revenue standpoint as compared to just our lasers. You want to give two seconds of color?

Yeah, certainly. Thanks, Michael. Not only the pluggable EOSFP opportunity, but we talked about earlier, actually, the scale-up opportunity there, I think that's brand new, right? When we compared before the module opportunities, pluggable module opportunity versus the CPU opportunity, it was a wash just from a scale-out kind of a comparison. But now, in a scale-up opportunity here is a brand new market that didn't exist before. So therefore, I would say that our overall market share on the scale-out market will be improving because of acquisition in the laser front, and then by extension, the pluggable light source market. And then on top of that, when the scale-up actually happens, then that's another big chunk of time that didn't exist before. And therefore, overall, I think this scale-out and scale-up with CPO will benefit us meaningfully going forward. Very helpful. Thank you so much.

Thanks, Papa. Thank you, Papa.

And your next question comes from Ruben Roy of Stiefel. Your line is open. Please go ahead.

Hi. Thank you. Michael, I apologize if you answered this already, but I just wanted to go back to the OCS momentum and just thinking through the order backlog improving. Is that still sort of relegated to a single customer and just sort of momentum at that customer? Are you seeing a broadening of orders from multiple customers? And I guess a follow-up for Wupen on that topic is just in terms of applications, what are some of the new applications for OCS that are coming up? And, you know, have you seen actual orders for things outside of maybe spine switch replacement and some of the other applications that you've already been delivering to?

Yeah, Ruben, and, you know, thanks again for your support over the quarter. Appreciate some of the things you've helped us with. You know, number one, the strength of the backlog, and we did answer this previously, it is coming from multiple customers, not just one. We feel very good about our volumes in the business. You know, this $400 million that we're talking about primarily deliverable in the back half of the year sets us up well above what we previously outlined, which was sort of $100 million exiting calendar Q4. So our run rate going into 2027 is quite a bit higher. and we would expect obviously in 2027 to do better again so it is setting up for us nightly it's broad-based right it's it's three customers are making up that backlog and um you know we are definitely have stepped on the accelerator relative to deliveries even this quarter to to all three of those customers we'll bet on the applications right again fairly broad-based but why don't you give some color to Ruben?

Yeah, I would say no changes to the applications. As we recall, I think we talked about before, there were primarily four different applications, right? One is the spine replacement, as you mentioned. One is the scale across applications we also talk about. And two more are really the optical scaled-up application for protection or redundancy in the network. Actually, we see these applications in all the customers to different degrees. And therefore, I would say that these multiple customers are covering these four different use cases in the applications. I think there may be some other potential scenarios showing up. We're definitely watching very, very closely. But these four, to us today, they are dominant application scenarios.

Great. Thanks. Just a very quick follow-up. Has anything changed with the way you guys are thinking about 800 gig versus 1.6 target module mix this year, one way or the other? Is it accelerating towards 1.6 T for any reason in terms of volumes from a single customer or multiple customers, or is it relatively unchanged from how you're thinking about it 90 days ago? Thanks.

Yeah, 1.6T is definitely stronger than we felt, you know, than we felt 90 days ago. So 1.6T is definitely accelerating. Our 800 gig volume actually is doing better than we would have expected. So in 800 gig, what you're seeing right now from us is an acceleration of revenue on our 800 gig shipments. But in the market, to your question, Ruben, 1.6 T is definitely going better. We have exposure to a couple of customers, a couple of large customers on 1.6 T. and we've been surprised by how quickly they're trying to push us to deliver and their forecast to us relative to the different SKUs that we're being asked to deploy. I mean, any different thoughts, Wupan?

Yeah, definitely. I think there are two factors there, right? So one is the 800 is still a very large market today. However, our market share at 1.60, as Michael talked about earlier, is actually higher as we kind of get our acts together on the development side. So we definitely are seeing for our business 1.6T trend, growth trend is a lot stronger than 800G, even though the 100G continue to be going forward. But the surge 1.6T business is coming our way for this calendar year.

Very helpful.

Thanks, Ruben.

Thanks, Ruben. Kevin, I think we have time for just one more question.

All right. Your next question comes from George Nauter of Wolf Research. Your line is open. Please go ahead.

Thanks very much. I just wanted to kind of get in here and ask some questions about supply. You know, it just seems like obviously there's a tremendous amount of demand here. I know you guys have been trying to consolidate more and more of your manufacturing into the Nava facility down in Thailand. And, you know, I'm just curious about what that looks like right now in terms of, you know, capacity, available capacity in Nava. you know, is it possible that you guys would look to outsource more, you know, given the demands you're seeing? Just walk us through kind of, you know, how you plan to ship all this product. Thanks.

Yeah, George, that is the right question. I mean, we have pivoted from a manufacturing strategy to really look at more contract manufacturing. We have stepped on the gas at Nava. uh we're doing everything we can to clear out some of our factory footprint actually in china to help us with some of the most important skews that we're going to be able to deliver to uh so we've we've really tried to work to optimize our floor space that we have for the high value products that we think we need to deliver that being said we simply don't have enough. I mean, right now, one of the significant challenges we're facing is, you know, in addition to fab capacity, which is well documented, is our factory capacity. And there, we're starting to look a lot more to contract manufacturers than we have in the past. We did hire a new leader for our backend operations that came from Jabil. He is very familiar with the contract manufacturing community. He and Wu Pan were actually meeting last week in Thailand, outlining a strategy by which we can move a lot more of our products to CM, just to help us accelerate these various ramps. We're facing so many challenges right now from a ramp perspective that to not rely on

partnerships would be stupid. Got it. Then just one quick follow-up. You mentioned the LTAs, I think more in the context of the EML supply that you have. But, you know, if I look at the telecom business, I look at transceivers, other components in the business that are really sort of asymmetric in terms of supply and demand. Are you also putting LTAs into those product lines as well? I'm just curious, like how much of the business is now covered with LTAs? Thanks a lot, guys.

Yeah, we are. I mean, that is that is definitely been a pain point because I think that there's been a lack of recognition from the historical telecom customers as to, you know, right now it's a seller's market. And so a couple of a couple of our key customers have been problematic around the LTAs. And Ben and I have been able to sort of get to to a reasonable compromise with those customers. But honestly, we'd like to do more there. I think there's more opportunity for us to increase price on the telecom customers than we have in the past. And we're going to look at that, you know, and pick some partners that really are working with us, quite frankly, better. And those customers, I think we're going to treat favorably. And, you know, we'll figure out how to service the rest with the volume that's left over.

Thank you.

Thank you, George.
