Lumentum's press release with the fiscal third quarter results and accompanying supplemental slides are available on our website at www.lomentum.com under the Investors section. With that, I'll turn the call over to Michael.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Thank you, Kathy, and good afternoon, everyone. Before diving into our third quarter results, I want to reflect on my first ninety days as CEO of Lumentum. I joined because of the immense cloud and AI opportunity. And the more I've seen, the more confident I am that we're poised for success. Having said that, we have opportunities to accelerate revenue growth, improve margins and focus spending.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

As many of you know, part of my core philosophy is that gross margins reflect the value customers place on our products. As we indicated at OFC, we see a path to take gross margins above 40%. Meanwhile, we can and should be able to improve operating margins by cutting spending in non core areas. At OFC, we outlined a path to drive revenue to $750,000,000 a quarter, gross margins above 40% and operating margins greater than 20%. Based on my initial observations and the plan we have in place, these targets are all achievable.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Our markets are growing at unprecedented rates, greater than 25% compound annual growth rate over the next five years, driven by an accelerating convergence of optics and electronics. Our strength in optical components is unmatched. We build for virtually every type of network. At OFC, we showcased our 400 gig lane speed lasers alongside our proven 100 gig and 200 gig solutions. We also demonstrated differential drive VMLs that boost signal integrity and power efficiency.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

We're building momentum in the transceiver market with three cloud transceiver customers already onboard and more wins expected in the pipeline. What sets us apart is that our components are embedded across the ecosystem, even in competitors' transceivers. That means we often win regardless of who supplies the module. We're one of the few companies with true end to end optical capabilities from long haul to metro to inside the data center. Our scale and breadth make us a truly differentiated optical solutions provider.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Let's now turn to our third quarter results. In Q3, we exceeded the high end of our guidance for both revenue and EPS, driven by strong demand from cloud customers and recovering networking market. Despite ongoing macroeconomic volatility, growth in cloud continues to be a key element of our financial performance. Revenue in our Cloud and Networking segment grew 8% sequentially and 16% year over year, fueled by robust demand from hyperscale cloud customers. As mentioned earlier, when we execute well, the opportunity ahead is significant, and our components business is performing at an exceptional level.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

We set another record for EML chipset shipments this quarter and remain on track to more than double this business by the end of calendar twenty twenty five relative to our June 2024 baseline. We continue to ship 200 gig lane speed EMLs to multiple customers. With our set of design wins, we're well positioned in the next generation of 800 gig and 1.6T transceivers supporting AI workloads. Our wafer fab expansion remains on track, supporting higher volumes of EMLs and other indium phosphide lasers and photodetectors. In addition, we are ramping production in CW lasers for silicon photonics transceiver applications in the quarter.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

As our indium phosphide capacity grows, we expect to ship an increasing mix of CW lasers. In addition to supplying components into the transceiver market, we took an early lead in co packaged optics, or CPO. We have a highly differentiated ultra high power laser that was announced as a key component in a CPO solution at GTC last quarter. We have already shipped early production units of that product and expect meaningful revenue in the second half of calendar twenty twenty six. At OFC, we introduced the R300, a 300 by 300 port optical circuit switch, or OCS, engineered to significantly improve the scalability, performance and efficiency of AI clusters and intra data center networks.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

The device replaces traditional switches, providing customers significant power benefits by keeping signaling in the optical domain. Our OCS solutions build on decades of engineering expertise and the successful deployment of high performance MEMS technology in demanding telecom environments. With over 1,000,000,000,000 mirror operating hours in the field and a robust patent portfolio, our optical switches are designed for high reliability and energy efficient performance in AI driven data centers. At present, we have beta samples being qualified by multiple hyperscaler customers and expect to see early production volumes at the end of the calendar year. We're accelerating our optical transceiver production at our Thailand manufacturing campus and remain on track to begin shipments to our second announced hyperscale data center customer in June, as previously communicated.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

At the same time, we continue to ship to our third announced customer, and we are expanding our product offerings and ramping in shipment volume to our largest cloud hyperscale customer. In Q4, we expect our overall cloud transceiver revenue to grow over 50% sequentially. We're also experiencing growing demand for our DCI and long haul transmission solutions. We achieved another sequential increase in shipments of narrow linewidth lasers essential to ZR and ZR plus module deployments and in transponders for cloud customers. This marks the fifth sequential quarter of shipment growth for narrow linewidth lasers.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Even as we ramp additional capacity in Thailand, our shipments will not be able to satisfy demand for the balance of the calendar year. In addition, pump lasers and line subsystems were up sequentially, driven by cloud infrastructure demand. Looking ahead to Q4, we anticipate strong sequential growth in our cloud and networking segment, driven by new capacity coming online across our global operations, the continued ramp of customer programs and strengthening demand from network equipment manufacturers. Now let me move to our Industrial Tech segment. Industrial Tech segment revenue decreased 5% sequentially, but was up 14% from the same quarter last year.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Industrial laser revenue declined sequentially, but the drop was less than anticipated, while three d sensing revenue followed expected seasonal trends. In Q3, ultrafast laser shipments held steady at near record levels, driven primarily by growing demand from a leading tool supplier supporting high volume solar cell manufacturing. We're also actively collaborating with customers on new ultrafast laser opportunities as the minimal thermal impact of ultra short pulse technology continues to gain traction in advanced packaging, display technologies and next generation semiconductor processes. Consistent with earlier remarks, we have taken actions to rationalize the industrial tech portfolio, closing two R and D sites and stopping development activities in three exploratory product areas. With these actions and more focus on the core business, we expect to see increasing profit in this segment over the next handful of quarters.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Looking ahead to fiscal Q4, we expect a sequential decline in Industrial Tech revenue, reflecting both the ongoing macroeconomic headwinds impacting industrial laser demand than the typical seasonal decline in three d sensing revenue. As I reflect on my first ninety days at Lumentum and look ahead, I'm energized by the momentum we're building. Our strong Q3 performance, combined with the strategic positioning we shared at OFC, reinforces that we're on the right path. We're executing on a focused strategy, investing in high growth, high impact areas where our differentiated technologies provide a lasting competitive advantage. From delivering record EML chip shipments to partnering with AI hyperscalers on connectivity innovation, we're demonstrating that our products are essential to powering the future of cloud and AI.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

While macro uncertainty, tariff dynamics and export controls present near term challenges, Lumentum has taken recent actions and delivered steps over the years to build resilience through a globally diversified manufacturing footprint, a flexible supply chain and active engagement with customers. We remain focused on what we can control: pricing, disciplined spending and flawless execution. These fundamentals are positioning us to succeed across a variety of market environments. Finally, strong demand for cloud and AI continues to support our confidence in achieving the medium and long term financial targets we outlined at OFC. We remain on track to exceed a $500,000,000 quarterly run rate as we exit the calendar year.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

There's still work ahead, but the opportunity in front of us is substantial. Our ability to deliver differentiated optical solutions across our portfolio provides a strong, resilient foundation for sustainable growth. Now I'll hand the call over to Wajid.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Thank you, Michael. Third quarter revenue of $425,200,000 and non GAAP EPS of $0.57 were both above the high end of our guidance ranges. GAAP gross margin for the third quarter was 28.8%, GAAP operating loss was 8.9%, and GAAP net loss per share was $0.64 Turning to our non GAAP results. Third quarter non GAAP gross margin was 35.2%, which was up two ninety basis points sequentially and up six fifty basis points year on year due to better manufacturing utilization and favorable product mix due to increased datacom laser shipments. Third quarter non GAAP operating margin was 10.8%, which was up two ninety basis points sequentially and up 1,100 basis points year on year and driven by improved cloud and networking profitability.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Third quarter non GAAP operating profit was $46,100,000 and adjusted EBITDA was $71,000,000 Third quarter non GAAP operating expenses totaled $103,400,000 or 24.3% of revenue, an increase of $5,100,000 from the second quarter and a decrease of $2,400,000 from the year ago quarter. This demonstrates our disciplined cost management across the organization, even as we ramp investments in our growing cloud opportunities and absorb the typical payroll fringe reset that takes place each year in our third fiscal quarter. Q3 non GAAP SG and A expense was $40,100,000 Non GAAP R and D expense was $63,300,000 Interest and other income was $2,900,000 on a non GAAP basis. Third quarter non GAAP net income of $40,900,000 and non GAAP diluted net income per share was $0.57 Our fully diluted share count for the third quarter was 72,200,000.0 shares on a non GAAP basis. Turning to the balance sheet.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

During the third quarter, our cash and short term investments decreased by $30,000,000 to $867,000,000 Our inventory levels increased sequentially to support the expected growth in our cloud and networking revenue. In Q3, we invested $59,500,000 in CapEx, primarily focused on expanding clean room capacity at our Thailand manufacturing site and increasing equipment capacity for indium phosphide wafer production to support EML chip manufacturing. Nearly all of our CapEx investment was directed toward our cloud and networking business. Turning to segment details. Third quarter cloud and networking segment revenue at $365,200,000 increased 8% sequentially and 16% year on year.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Cloud and networking segment profit at 20% increased three eighty basis points sequentially and increased five forty basis points year on year on higher revenue and favorable product mix. Our third quarter Industrial Tech segment revenue at $60,000,000 was down 5% sequentially and up 14% year on year. Third quarter Industrial Tech segment profit of 4.3% decreased sequentially on lower revenue and increased year on year on higher revenue. Now let me move to our guidance for the fourth quarter of fiscal twenty twenty five, which is on a non GAAP basis and is based on our assumptions as of today. I want to acknowledge that the impact of tariffs on our supply chain, along with broader geopolitical dynamics, remains highly uncertain.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

The guidance we're providing reflects our best assessment based on the current environment. This outlook includes an estimated 100 basis point reduction in overall company gross margin, primarily driven by higher material costs and tariffs on shipments to U. S. Destinations where we serve as the importer of record. For clarity, despite this 100 basis point headwind, we expect a sequential improvement in gross margins from Q3 to Q4.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

We expect net revenue for the fourth quarter of fiscal twenty twenty five to be in the range of $440,000,000 to $470,000,000 This Q4 revenue forecast includes the following assumptions: Cloud and networking to be up sequentially with strong growth in products addressing cloud and AI applications and industrial tech to be down sequentially with declines in both industrial lasers and three d sensing. We project fourth quarter non GAAP operating margin to be in the range of 13% to 14% and diluted net income per share to be in the range of $0.70 to $0.80 per share. Our non GAAP EPS guidance is based on a non GAAP annual effective tax rate of 16.5%. These projections also assume an approximate share count of 72,700,000.0 shares. With that, I'll turn the call back to Kathy to start the Q and A session.

Wajid Ali

Kathy?

Kathy Ta
Kathy Ta
Vice President-Investor Relations at Lumentum

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

Operator

Our first question is from Samik Chatterjee with JPMorgan. Your line is now open.

Joseph Cardoso
Joseph Cardoso
Vice President, Equity Research at JP Morgan

Hi, good evening. Thanks for the question. This is Joe Cardenso on for Sonic. I guess first question and maybe just a big picture question. I noticed you guys didn't necessarily talk about the $500,000,000 revenue target that you initially laid out achieving by the end of the calendar year.

Joseph Cardoso
Joseph Cardoso
Vice President, Equity Research at JP Morgan

I guess kind of recent performance in the June guidance, how are you thinking about achieving that target by the December? Is there the possibility that you can achieve that a bit earlier? And what are the puts and takes to your expectations there? And then I have a follow-up.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Yes. Let me take that one. This is Michael Hurlston. So we did outline that. We're still very much on track for the $500,000,000 by the end of the year.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

We're obviously not guiding we're guiding a quarter at a time, but we feel pretty pleased about where the company is setting up and still, as we said in the remarks, are very much on track for the $500,000,000 quarter.

Kathy Ta
Kathy Ta
Vice President-Investor Relations at Lumentum

Did you have a follow-up, And then maybe just a yes, yes, definitely have

Joseph Cardoso
Joseph Cardoso
Vice President, Equity Research at JP Morgan

a follow-up. So maybe just talk maybe just touching on the datacom chip business. I think you were initially targeting a 40% increase in volumes by the June. I guess just wanted to get an update there in terms of how it's tracking relative to your initial outlook and whether you're outperforming your initial expectations both on the volume and ASP front? And and similar question, but obviously more related to kind of the calendar twenty five outlook.

Joseph Cardoso
Joseph Cardoso
Vice President, Equity Research at JP Morgan

It does look like you're you're kinda outperforming your initial expectation in terms of where you were gonna track towards the end of the calendar year. But any kind of color in terms of how you're thinking about ASPs trending there? And then sorry for the long question, but, just curious, like, what's the contribution that you're expecting from CW lasers now that you're talking about ramping those up, as well as EML? Thanks.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Yes. I'm going to take the first part of the question and then turn it over to Wu Pen. So what I would say, look, we're obviously tracking very well. We've increased our capacity in the indium phosphide fabs. We feel like demand is still outstripping supply on our EMLs.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

So we even as we ramp supply, we're still very much sold out. That being said, as we increase the capacity, we feel like there's room to add CW into the mix. And the reason for that is it really extends our serviceable market. So we feel like we want to do that to get a foot in that door. Our design, we think, is differentiated and gives us an opportunity to meaningfully participate in CW.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

But the predominant focus is and remains EMLs. From an ASP standpoint, again, given the supply constraints, obviously, there's opportunities there to continue to maximize our price and we're looking at that. We have opportunities as we think about now transitioning from 100 gig to 200 gig lasers and obviously going up to 400 gig. But maybe Wupang, want to add some color on the tech and how we think about it?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Yes.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

So I'll just comment a

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

little bit on the the several laser ramp. We're at the very beginning, right? We just won a couple of customers at several lasers as Michael pointed out. As our fab capacity continue to be ramping up, we would like to be able to play in that market, which increase our fan. So we're at the very initial phase of the ramping.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Not huge numbers yet, but we will continue to see that volume going up as time goes by.

Kathy Ta
Kathy Ta
Vice President-Investor Relations at Lumentum

Thanks, Joe.

Joseph Cardoso
Joseph Cardoso
Vice President, Equity Research at JP Morgan

Thanks, guys. Appreciate it.

Operator

Our next question is from Simon Leopold with Raymond James. Your line is now open.

Simon Leopold
Simon Leopold
Managing Director at Raymond James Financial

Thank you very much. I I wanted to see if you could maybe unpack what's, in your assumptions around the the tariff headwind. You you quantified it around a hundred basis points, which we appreciate. I I guess what I'm trying to get at is trying to get a sense of how much business or manufacturing do you still have in China in that assumption. I I I understand you're moving more to Thailand.

Simon Leopold
Simon Leopold
Managing Director at Raymond James Financial

And what are the other underlying assumptions you've made? Then I've got a quick follow-up.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Yes. Sure, Simon. I'll start off, and then certainly, Wupin and Michael can jump in. Yes. So like you mentioned in our prepared remarks, we did talk about the 100 basis point headwind to gross margins and therefore operating margins during the quarter.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

A lot of that headwind is coming from increased component costs, so called in feed costs, where we are having to pay the tariff associated with sub mount products as well as capacitors. And so wherever we see that, we're having to pay a tariff associated with that. For most of our customers, we are trying to move our production from China into our Nava facility in Thailand. We're starting off with our data center interconnect products, but we are eventually going to also be moving products from our Dongong facility for cloud modules into Nava as well. So what we've baked into the forecast right now is our current production ramp for the quarter, but we'll see improvements in that in our fiscal Q1 and Q2 as more of our Dongguan production moves to our Nava facility for cloud modules.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

So certainly, the impact from that perspective will diminish.

Simon Leopold
Simon Leopold
Managing Director at Raymond James Financial

Thanks. And then just as my follow-up, longer term question is I'd like to get your latest thinking on what contributions and what role you can play in CPO. I I it's nice to see that you were announced within the the ecosystem back in March. I assume you're providing products like CW lasers, but could you get an idea of maybe some dollar content and and forecasting of how you see this affecting your business over the intermediate or longer term? Thank you.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Hey, Simon. This is Wu Han speaking. I think the, you know, CPO, frankly speaking, there's still some times away. Right? We talk about, you know, ramp volume in second half of the of the next calendar year, number one.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

So therefore, in the meantime, the module is gonna be continue to be a ramping business for us. That's gonna be, you know, be a a foreseeable, you know, strong growing business for us and for the for the industry to come. On the other hand, you know, in addition to the laser being a important component in the CPO ecosystem, we're also looking at adding other components in the longer term. There'll be other optical chips that will be needed in the CPO world in the in the longer term. That's very much we're actually looking into as well.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

But I would say that's really a multiyear prospect. In the near term, it's gonna be the laser components plus the cloud module ramping in the cloud interconnect world.

Simon Leopold
Simon Leopold
Managing Director at Raymond James Financial

Thank you.

Kathy Ta

Vice President-Investor Relations at Lumentum

Thank you so much, Simon.

next question is from Blayne Curtis with Jefferies. Your line is now open.

Ezra Weener
VP - Equity Research at Jefferies LLC

Hi. Ezra Wiener on for Blayne. Thanks for taking my question. Just a quick one and then probably a follow-up. Just look at the transceiver business, 50% plus growth for next quarter is great and clearly a lot of traction.

Ezra Weener
VP - Equity Research at Jefferies LLC

Can you talk about what you're seeing there from an EML versus CW laser perspective and the plan for insourcing versus externally sourcing there?

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Yes. Near term, all of our products are using CW lasers. So we're using silicon photonics approach for all of that, including all the revenue growth that you just cited. And all of it actually is externally sourced. So we have not yet incorporated our own lasers in our transceivers, but we would expect to do that sometime early in the calendar year next year.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

That's kind of the plan. We obviously have a number of big ramps in front of us with multiple customers that we talked about. But we our next phase of growth will incorporate our internal lasers. Wupin, anything to add? Okay.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Good. Thanks for the question.

Ezra Weener
VP - Equity Research at Jefferies LLC

Just a quick follow-up in

Ezra Weener
VP - Equity Research at Jefferies LLC

terms of Thanks. So, that would be three customers all using CW lasers. Just kind of wondering what that means for the industry in terms of what you're seeing from people choosing CW or EML?

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Yes. I mean, obviously, as we've talked about a second ago, our EML are very much sold out. In fact, it really is a chase for us to keep up with the demand. We are basically choosing to allocate our supply toward EML, one, because of differentiation two, because of pricing. So we've really focused our capacity as much as we possibly can on the EML product.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

As we said, we're really increasing the capacity quarter on quarter, year on year. And as we sort of hit a space where we think we have a bit of room, we think there's an opportunity now to reallocate just a bit towards CW so we can start participating in that market first externally, right? We'll source those to third party transceiver customers. But then strategically, to your point, we will begin insourcing those. So it will be mostly CW that we end up insourcing, And that's why strategically it is important for us to develop that muscle.

Operator

Our next question is from Meta Marshall with Morgan Stanley. Your line is now open.

Meta Marshall
Meta Marshall
Managing Director at Morgan Stanley

Thanks. Would you maybe just some clarity on the margin improvement that you saw on the cloud and networking business. How much of that is from some of the yield improvements on Cloud Lite versus just kind of pricing mix advantages on EMLs? And then I have a second question.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Yes. Sure, Meta. I mean, we're seeing across all the product lines a nudge of improvement, I would say. On our data center interconnect products, we are moving a lot of that production from CMs to our own internal manufacturing in Thailand. And so the margin dollars that used to accrue to them are now accruing to us.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

So that's certainly helping us both in Q3 and more substantially in Q4. And actually, expect to increase that capacity moving into the back half of the calendar year. So that will continue to benefit us. On the datacom chip side, Michael and Wupen both mentioned earlier that demand is ahead of supply. And so as that production has improved year over year and sequentially, that's also providing a tailwind for us.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

To your earlier question on modules to the first part of your question on modules, yes, yields have improved. And so the yield issue that we had in our December, which caused a bit of a headwind on our gross margin line, that situation has improved into Q3 and that certainly helped us. And into Q4, that's also helping us, especially as revenues are expected to increase 50% sequentially, the benefit of improved yields are accruing to our gross margin. So I'd say kind of across the board, we're seeing a nudge of improvement across multiple product lines, and that's helping us.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

And Meta, I mean, just from a perspective, we said this in the prepared remarks, but we're sorry, Meta, we're going to continue to focus on gross margin. I think there's opportunity on pricing and on our cost line to continue to improve that. So we'd expect a pretty nice ramp toward the 40% target that Wajid outlined at OFC.

Meta Marshall
Meta Marshall
Managing Director at Morgan Stanley

Okay. Got it. And just as a second question, obviously a very fluid situation with tariffs currently. But assuming kind of the 100 basis point headwind that you guys are talking about is within that kind of ninety day exemption period kind of considering current tariffs as of that. And just kind of wondering what your thinking is, if there are kind of greater tariffs that come from Thailand, just our thoughts about eventually moving production out of Thailand.

Meta Marshall
Meta Marshall
Managing Director at Morgan Stanley

It sounds like you're moving more production there for now, but just kind of overall thinking if there ends up being tariffs on Thailand? Thanks.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Yes. I mean, obviously, there are tariffs on Thailand, that will have a headwind that we'll have to work through. Yes, we are moving more of our production to Thailand, whether it's from our CMs to us or whether it's from our cloud module business in Dongguan, China to us in Thailand. So we are making that manufacturing shift that's been in place for a number of quarters now. And so I think from an infrastructure and strategy standpoint, that certainly is there.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

If there's tariffs that accrue post kind of July 8 because of that, then we'll have to work through that with our customers. And as you can appreciate, as there's been noise on tariffs, we've been speaking to our customers about how we work through the pricing impact to them that is associated with those tariffs. But up until now, for the large part, most of our shipments that come to The U. S, we are not the importer of record. And because we are not the importer of record, those conversations have been a lot simpler, I'd say.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

So that's really how we're thinking about it.

Operator

Our next question is from Christopher Rolland with SIG. Your line is now open.

Dylan Ollivier
Equity Research Associate at Susquehanna International Group

Hi, this is Dylan Olivier on for Chris. Thanks for taking my question. So for my first question, I wanted to follow-up on the 50% sequential growth in the optical transceiver business. So which of your transceiver customer programs will be responsible for that growth? And how should we expect transceiver shipments to trend for the rest of the calendar year?

Dylan Ollivier
Equity Research Associate at Susquehanna International Group

Do you guys think that level is sustainable? And are you guys expecting to grow from there as you add customer programs?

Dylan Ollivier
Equity Research Associate at Susquehanna International Group

Yes.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

On the transceivers, I mean, don't want to necessarily outline specific customers that are driving it, but it's predominantly the customer that we've had shipping for quite some time will be most of the contribution. We would expect this business to continue to grow. I think we're really well positioned. Obviously, generally speaking, our share is relatively modest. We think that we've put some of the issues behind us relative to some issues transferring products into manufacturing and getting those into production.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

And we would expect from here to continue to grow. Will we grow at this growth rate? Hard to say, but certainly, we would expect to continue to grow this business, and it will be a major growth driver for us in 2026. Hoopad, any comments from you?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Yes. And also, as Michael said, as the more programs start ramping, we will see this to be more broader based than this one major customer ramp. Other programs will be gradually brought be brought into the ramping phase as well. So we're gonna see that going forward.

Kathy Ta

Did you have any follow-up?

Dylan Ollivier
Equity Research Associate at Susquehanna International Group

Got it. That's great. Yes. So for my follow-up, I wanted to ask about 200 gig EMLs. So it sounds like you're getting solid traction there already.

Dylan Ollivier
Equity Research Associate at Susquehanna International Group

When should we expect that to ramp? And do you expect it to quickly cannibalize 100 gig EMLs or just to layer on top initially?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Yes. This is Upheng here speaking. I think the timing wise is gonna be toward the end of this calendar year. That's when 200 g m l will start to ramp. And we don't see this being a cannibalization of hundred g m l's because there's still a very large growing demand for hundred g m l for 800 g modules.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

1.6 modules or solutions will be on top of the hundred g demand for quite a while to come. So this should be additional opportunities than a cannibalization opportunity.

Our next question is from Ryan Koontz with Needham and Co. Your line is now open.

Ryan Koontz
Senior Analyst at Needham & Company

Thanks for the question. Maybe stepping back a little bit on the intercom transceiver market here relative to, you know, the strong Chinese players. What are you hearing from your customers, your major, you know, cloud oriented customers about their interest in moving away from Chinese suppliers and interest in bringing those products in house? Thanks.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Yes. No, there's definitely an interest to move away from Chinese supply. I mean, I think the problem right now is that collectively we can't meet the demand. So they are going to continue, I think, buy from Chinese suppliers until U. S.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Suppliers can ramp to a level to meet what looks like a relatively insatiable demand. Generally speaking, is some design in sourcing going on. Some of the customers are doing their own designs, but the outsourcing is by far the dominant pole working with third party transceiver manufacturers. We obviously are a small player at the moment. We expect, given the number of designs that we have in flight, we expect to be a more meaningful participant in the market starting next quarter, but then really growing into the quarters beyond that.

Ryan Koontz
Senior Analyst at Needham & Company

That's great. You. And then maybe I do. Yeah. Thanks.

Ryan Koontz
Senior Analyst at Needham & Company

On the telecom side of the business, what kind of mix shifts you're seeing there? Obviously, DCI is driving the boat there in terms of growth. As you think about that mix shift, is it kind of in line with your expectations? How should investors think about the shift toward DCI and how it affects your business, whether it's measured on gross profit or revenue per unit, these sorts of things, wallet share? But if you could just step back and explain how investors should think about these shifts in telecom, it

Ryan Koontz
Senior Analyst at Needham & Company

would be helpful. Thank you.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Yes. I mean, I think that the traditional telecom business targeted to operators and target to MSOs is still obviously meaningful, but the long pole now is the hyperscalers. So DCI, very important. Even these guys are now participating in our long haul business. So we talked in the call and the prepared remarks about pump lasers.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

We've seen really an increase in that business. A lot of the backbone now is being supplied by the hyperscalers, and we're participating in that with our traditional telecom products, but now more targeted toward the hyperscalers. So that's been a surprising growth driver. I think quite frankly, we haven't seen this business perform at these levels in quite some time. So it's really a nice surprise.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

I mean, technical technology wise, we've had any other things that you're seeing from a trend line?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Yeah. Certainly, I think the overall, we should think about the the AI driving force is not just about data center internal. Data has to be transmitted across data centers. So all these actually have the same driving source. Right?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

We see the Doctor being growing very strong, and therefore, TenableLaser is doing really well. You know, even the the long distance transmission coherent components are doing very well because of the the terrestrial long haul requirements and also the pump lasers for fiber capacity. So all in all, we're seeing a very strong, you know, DCI kind of traffic growth, and that's driving our so called telecom part of the portfolio as well.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

I'll just add an additional comment, Ryan. Around your question on gross profit dollars. DCI products are accretive to us from a gross margin standpoint, not only where we're currently operating from a gross margin standpoint, but also versus the 40% target that Michael laid out earlier, it's even accretive to that. And the combination of increased demand and our increased capacity internally at Thailand is certainly a tailwind for us that is driving a lot of the confidence that you're hearing from the team around our gross margin abilities is coming from the secular demand along with internal manufacturing, along with the pricing power that we believe we have on our data center interconnect products. So it's all adding up together.

Karl Ackerman
Managing Director - Equity Research at BNP Paribas

Yes. Thank you. I

Karl Ackerman
Managing Director - Equity Research at BNP Paribas

have two. I believe you said that your cloud transceiver revenues would grow 50% sequentially on the on the contribution from all three of your cloud customers. I have to ask, though, is is this tied to it sounds like it's tied to a new GPU or ASIC program ramping, at least at one of them. But, you know, I guess, how much of this, if at all, is from customers pulling forward transceiver demand ahead of potential tariffs? And if not, how do you manage that supply and demand balance with these three customers?

Karl Ackerman
Managing Director - Equity Research at BNP Paribas

And I have a follow-up, please.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Hey, Carl.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Michael Hurlston. So first of all, we don't see any pull forward. I mean it's been a race for us to keep up. We kind of alluded to this in one of the previous questions. We definitely had an issue ramping.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

We went through a ramp phase and then a qualification phase. And really, this is a product that's driving a lot of the increase that was something that's been in our hopper now for a couple of quarters. So we certainly don't see a pull forward effect. And again, with that layering in with the additional two customers beginning to ramp this quarter, we feel we don't see any effect on pull ahead. I mean, have Wumpen talk a little bit about what those are tied to relative to kind of the customer tech.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Yeah. I think the from the product release point of view, definitely, I think those ramps are tied to the the dominant, you know, GPU ramp and and also some other accelerator ramp. There's some loose association with the with those kind of introduction of the accelerator products. But also though that the I think the demand is pretty broad based. It's not specifically only to those two or three accelerators that are being introduced now into the market.

Kathy Ta
Kathy Ta
Vice President-Investor Relations at Lumentum

Did you have a I

Karl Ackerman
Managing Director - Equity Research at BNP Paribas

did one, if I may. Rajeed, you spoke of moving production away from contract manufacturers to in house solutions. I'm curious, is that for your industrial tech products? Or does that relate more toward cloud and networking? And similarly, do you need to add substantial capacity to move that production in house, please?

Karl Ackerman
Managing Director - Equity Research at BNP Paribas

Yes.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

So it's revolved around our data center interconnect products. And so that those CapEx decisions were made six to nine months ago. And actually, the CapEx is showing up this fiscal quarter, and it's expected to improve our capacity for data center interconnect products by 50% exiting this calendar year. And so that is the production that instead of providing to our contract manufacturers, we're still keeping them going at full speed, but the incremental supply is coming from our Nava facility for CapEx that is being put in place this quarter and that will fully ramp by the end of this calendar year and give us another 50% more capacity on data center interconnect products, specifically tunables.

Kathy Ta

Our next question is from Mike Genovese with Rosenblatt Securities. Your line is now open.

Mike Genovese
Senior Research Analyst at Rosenblatt Securities

Great. Thanks. I'm not sure if I missed this in the prepared remarks, but

Mike Genovese
Senior Research Analyst at Rosenblatt Securities

did we just get an

Mike Genovese
Senior Research Analyst at Rosenblatt Securities

did we get an update on telecom performance in the quarter and the sort of product issue last quarter with just getting supply, if has been solved yet?

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Yes, sure. So I'll start off and I'll let Wu Pan also jump in. So telecom performance came in exactly as expected. We had shortages on pumps. We had shortages on tunables.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

We had shortages on CDM products from our classic transmission product lines. And so all of those products we were working through supply constraints throughout the quarter. We are expected to see improvements in supply for all three product lines moving into Q4 and into the back half of the year. The earlier question was around our tunables products where we mentioned that we have CapEx that we're putting in place in our Thailand facility to increase the production capacity by 50% over the remaining part of this calendar year. So with that increased capacity, we're going to see the telecom part of our business improve as we move through the quarters for the rest of this calendar year.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Maybe you want to talk about pumps a little bit more, Wilpin?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Yes. I think the overall from a demand and supply perspective, we don't expect that our capacity can really fulfill all the demand for the next several quarters because of the demands being really strong. Although we're doing better than we we were able to. So we'll continue to ramp capacity, continue to get more supply into the picture, but we're going to be in a pretty tight supply situation for next at least next couple of quarters.

Kathy Ta
Kathy Ta
Vice President-Investor Relations at Lumentum

Did you have a follow-up, Mike?

Mike Genovese
Senior Research Analyst at Rosenblatt Securities

Great. Yes. And I guess I want to revisit the question whether there's any caution in the guidance for the back half of the year related to macro or tariffs. If I just take the transceiver comment up 50% sequentially, I mean, to me, that gets us $30,000,000 more revenue. That gets us the whole growth in the guide.

Mike Genovese
Senior Research Analyst at Rosenblatt Securities

I know industrial is supposed to be down, but you've got EMLs growing, you've got telecom that should be up. Is there an extra dozen conservatism in here? Or am I overthinking this?

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

I'd say you're not overthinking it, Mike. I mean, obviously, we're in an environment where there's a lot of uncertainty. We're quite confident in the guide that we've provided. But if you just listen to some of the capacity improvements that we've got, there is certainly opportunity to deal with any type of headwinds that come our way during the fiscal quarter. As far as the back half of the calendar year looks across all of our product lines, we continue to see an uptick in demand, whether that's datacom chips, whether that's data center interconnect products or whether that's modules.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

Even our industrial lasers product line that is going to that is expected to come down in fiscal Q4 has new ultrafast products that are ramping in the back half of the calendar year. Demand for those products is quite strong. But offsetting that, we're seeing some headwinds from customers that take kilowatt products. So but overall, the trend is up and our supply plan is up. We see improvements from here to the $500,000,000 target that Michael spoke about.

Wajid Ali
Wajid Ali
Executive VP & CFO at Lumentum

But again, I think the macro uncertainty, none of us have a great crystal ball on that.

Our next question is from David Bach with UBS. Your line is now

David Vogt
David Vogt
Managing Director at UBS Group

Great. Thanks guys for taking my question. I just want to go back to the telecom business for a second. I jumped on late and I apologize. Was there anything in the quarter that was similar to last quarter?

David Vogt
David Vogt
Managing Director at UBS Group

What I mean by that, there was some channel normalization last quarter and even in the quarter before. Just trying to get a sense for what's core underlying demand, particularly in the face of tariffs or the risk of tariffs or the potential tariffs. And I'll give you my follow-up. And I might have missed this because I jumped on late. Did you share with us sort of how the core transceiver business grew in the March relative to either last year or last quarter?

David Vogt
David Vogt
Managing Director at UBS Group

Thanks.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Yes. Maybe I mean, look, on the telecom business, obviously, we feel pretty good. I mean I think there's a lot of opportunities for us to continue to grow. Wu Pan talked about the narrow line with lasers. We actually said that in the prepared remarks.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

So we think that business continues to grow through the balance of the calendar year and into next year. And it's not just that. I think we talked about pump lasers. That really has been a strong product area for us. So across the board on telecom, which as Wajid said correctly, is a gross margin enhancer, it's accretive on the gross margin line, we would expect to see that to continue to creep up.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

Large portion of growth will be cloud modules. And so as you think about us across the next couple of quarters, in order to keep the gross margins up, we are going to need to see improvements in telecom because we think that that's an area for us that has accretive gross margins. On the datacom transceivers, the second part of your question, essentially that was flat on quarter. We didn't see a lot of growth. I think the growth for us we talked about it, I think, in previous discussions that we'd hit a bit of an air pocket relative to execution on some ramping some of our datacom transceivers.

Michael Hurlston
Michael Hurlston
President & CEO at Lumentum

We're past that at this point. We would expect to see the growth in this subsequent quarter in the guide, and then we expect to see pickup from there. So on balance, look, we feel really good about the way the business is shaping up. Wajid gave correctly a right amount of prudence around tariffs and macroeconomic uncertainty. But if we don't have that, we feel really good about where all of our business is landing right now.

Okay. Our last question is from Alec Valero with Loop Capital. Your line is now open.

Alek Valero
Equity Research Associate at Loop Capital Markets LLC

Hey, guys. Thank you for taking my questions. This is Alec on for Nanta. So I have a question on co package optics. What's your view on when co package optics truly have a chance to gain traction in data center and provide competition to transceivers?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Yeah. This is Wolfgang speaking. I think the cobotch optics would take some more time. The technology is pretty complex. A lot of engineering challenges, I think, yet to be worked through as the the leading AI customer talk about in their conferences.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

This year, there will be some a a first system release, and next year, c r '26, it'll be another system release based on the Ethernet switch. We we believe that's the timing. We're gonna see some level of adoption of the the CPO optics. However, though, we do believe that the the plug will continue to be the dominant form factor going forward. I think it will take the next several years really to gradually ramp the CPO optics to be a meaningful share.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

And the benefit of CPO is clear, but the adoption will take time for people to figure out how to use it very effectively.

Alek Valero
Equity Research Associate at Loop Capital Markets LLC

Got it. That's very helpful. And just as a quick follow-up, can you remind us economic difference between transceivers and co package optics?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

The the difference? The difference between transceivers. Oh, so so, basically, if you take any kind of a a switch box, for example, the the the transceiver basically is at the front panels. So you have the connection between the DSP sorry, the the switch chip in the signal all the way to the front panel of the box, which can be twenty, thirty inches actually away from the from the switch chip. The quadratic is basically remove all that, put the optics directly onto the switch chip, thereby removing all the signal losses and the complexities associated with that that transition.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

That in essence is what a CPO optics does. And then that lowers the power consumption, reduce the cost, reduce the the complexity. But in a sense, you actually move the complexity from optical modules onto the switch chip, which then is some engineering, you know, work to be done, right, to make sure that it is a reliable solution.

Alek Valero
Equity Research Associate at Loop Capital Markets LLC

Got it. And and

Kathy Ta

you.

Kathy Ta
Kathy Ta
Vice President-Investor Relations at Lumentum

Go ahead.

Alek Valero
Equity Research Associate at Loop Capital Markets LLC

Yeah. No. I was gonna ask, does does co pack its optics come with the ASP increase compared to transceivers?

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Well, it's a different pricing model. You know, today, the the consumption model is the the switch chip is purchased separately, and the box is made by somebody else, and the modules are purchased, you know, through third party manufacturers such as us. And, you know, it's a very different consumption model than the CPO optics, which basically means that the switch vendor will control the entire, you know, ASIC plus the optics. So it's very hard to say how they're gonna price it, and and therefore, how to say that which one's gonna be cheaper. We depend on the on the competition and benefit and so on and so forth.

Wupen Yuen
Wupen Yuen
President - Cloud & Networking at Lumentum

Very, very hard to give an estimation at this point.
