Greetings, and welcome to the Coherent Fiscal Year 2025 Second Quarter Earnings Webcast. [Operator Instructions] As a reminder, this conference is being recorded. It is now my pleasure to introduce your host, Paul Silverstein. Senior Vice President of Investor Relations for Coherent. Please go ahead.

Thank you, operator, and good afternoon, everyone. With me today are Jim Anderson, Coherent's CEO; and Sherri Luther, Coherent's CFO. During today's call, we will provide a financial and business review of the second quarter of fiscal 2025 and the business outlook for the third quarter of fiscal 2025. Our earnings press release can be found in the Investor Relations section of our company website at coherent.com. I would like to remind everyone that during our conference call today, we may make projections or other forward-looking statements regarding future events or the future financial performance of the company. We wish to caution you that such statements are predictions based on information that is currently available and that actual results may differ materially. We refer you to the documents that the company files with the SEC, including our 10-Ks, 10-Qs and 8-Ks. These documents contain and identify important risk factors that could cause actual results to differ materially from those contained in our projections or forward-looking statements. This call includes and constitutes the company's official guidance for the third quarter of fiscal 2025. If at any time after this call, we communicate any material changes to this guidance, we intend that such updates will be done using public forum such as a press release or publicly announced conference call. We will refer to both GAAP and non-GAAP financial measures during this call. By disclosing certain non-GAAP information, management intends to provide investors with additional information to permit further analysis of the company's performance and underlying trends. For historical periods, we provided reconciliations of these non-GAAP financial measures to GAAP financial measures that can be found on the Investor Relations section of our website at coherent.com. Let me now turn the call over to our CEO, Jim Anderson.

Thank you, Paul, and thank you, everyone, for joining today's call. I'd like to start by thanking my Coherent teammates for the strong execution in our fiscal second quarter and the continued focus and great progress on driving market-leading innovation. For our fiscal second quarter, revenue increased by approximately 6% sequentially and 27% year-over-year to a record $1.43 billion. This was driven by growth in multiple areas, including strong AI-related datacom transceiver growth, a second quarter of sequential growth in our telecom revenue and sequential growth across multiple key industrial end markets. As I mentioned when I first joined the company, in addition to growing the top line, expansion in our gross margin would be a strategic focus area for the company, driven by parallel initiatives on both pricing optimization as well as product cost improvements. During our fiscal second quarter, we made solid progress towards our goal of achieving durable company-wide gross margin of over 40%. Q2 non-GAAP gross margin of 38.2% marked strong improvement on both a sequential and year-over-year basis. While we have a lot more work to do on gross margin, I'm pleased with the team's focus and progress in this area. While we continue to invest in strategic R&D to fuel the long-term growth of the company, we remain focused on driving greater operational leverage and efficiency across the company. With revenue growth, gross margin expansion and disciplined OpEx management, we drove significant expansion and profitability in Q2, with non-GAAP EPS growing over 40% sequentially and more than tripling on a year-over-year basis. Again, we have much more work ahead of us, but we remain focused on driving long-term shareholder value. Let me shift gears and share some thoughts on our products and end markets. Starting with our data center and communications market, Q2 revenue…

Thank you, Jim. In the second quarter, we drove continued sequential improvement in our financial results with strong revenue growth and gross margin expansion driving strong profitability. In addition, we strengthened the balance sheet by paying down $132 million in debt. Now I will provide a summary of our results. Second quarter revenue was a record $1.43 billion, an increase of approximately 6% sequentially and 27% year-over-year. From a segment perspective, networking revenue increased 7% sequentially and 56% year-over-year, driven by ongoing strong AI data center demand and the continued recovery in telecom. Laser segment revenue increased 8% sequentially and 6% year-over-year, driven primarily by demand for our excimer annealing lasers in our display capital equipment business as well as strong demand in semi cap equipment. The Materials segment revenue increased 3% sequentially and decreased 4% year-over-year. The year-over-year decrease was primarily due to weak automotive end-market demand. Our second quarter non-GAAP gross margin was 38.2%, an increase of 146 basis points compared to the prior quarter and an increase of 363 basis points compared to the year ago quarter. The improvements in gross margin were driven by higher revenue volumes as well as cost reductions and improvements in manufacturing yields offset somewhat by unfavorable product mix. Second quarter non-GAAP operating expenses were $283 million compared to $278 million in the prior quarter and $239 million in the year ago quarter. The sequential and year-over-year increases were primarily driven by increased R&D investments in our product portfolio. SG&A decreased sequentially as a result of our disciplined approach to managing our SG&A expenses while ensuring that we invest in our product portfolio. Our second quarter non-GAAP operating margin was 18.5% compared to 16.1% in the prior quarter and 13.5% in the year ago quarter. Second quarter non-GAAP tax rate was 17.4%…

[Operator Instructions] Our first question comes from the line of Samik Chatterjee with JPMorgan.

Congrats on the strong results here. I guess, Jim, I wanted to get your thoughts, firstly, on the telecom market. You've been up sequentially in that end market now for 2 quarters, but I think last quarter also, you were sounding a bit more cautious relative to your outlook for that market. So if you can just share with sort of the second sequential quarter of growth, is your outlook for in terms of sustainability of that improvement? Has that changed? What are you hearing from your customers on that front? Or are you still sort of cautious in terms of the pace of improvement here? And I have a quick follow-up after that.

Yes. Thanks for the question, Samik. I think our view is we moved from cautious to cautiously optimistic. We were really pleased with the results that we saw in telecom in our fiscal Q2, the 16% sequential growth and 11% year-over-year growth in fiscal Q2. As you noted, that was the second quarter of sequential growth and we are expecting the telecom revenue to be up again sequentially in our fiscal Q3. So given all of that, we are cautiously optimistic that we've moved beyond the bottom of the valley in terms of the telecom recovery and demand, and we're on the up-slope within that market. And maybe just a little bit more commentary on what drove the sequential growth that we saw in fiscal Q2 is, one of the main drivers was growth in data center interconnect, and we expect that growth to continue into the current quarter. We also saw improvement in kind of traditional telecom transport market, which we view that sequential improvement is a really positive indicator for the overall underlying market health. And then we were really pleased with the continued ramp of our new products as well. So our 100-gig, our 400-gig and 800-gig ZR, ZR+ Coherent transceivers ramping nicely. We expect that to continue over the coming quarters as well. So yes, quite pleased with the telecom results and looking forward to another sequential improvement in the current quarter.

Got it. Got it. And for my follow-up, the OCS first orders that you're highlighting, that's an exciting announcement. Just if you can give us a bit more color in terms of how to think about the addressable opportunity here? And I know you've said probably the revenues are in calendar '25, but just how to think about the pace of the ramp with the customer and how material it will be in calendar '25 and what the longer-term opportunity there could be?

Thanks, Amit. Yes, really happy to talk about this product line. I love the differentiated technology of this product line. In fact, this was when I first joined the company, I guess that's about 8 months ago, this is one of the product lines that the team showed me early on. And when they explained to me the technology differentiation, it was -- I was quite impressed and we've since increased R&D investment in this area to expand and accelerate the road map on this technology, really, really pleased with the progress here. Maybe just to explain what OCS does for the customer is rather than when they're transmitting data from one computing node to the other computing node, rather than having to go through an electrical switch and switch the data from the optical domain into the electrical domain, by using an optical circuit switch, they're able to keep the signal in the optical domain through the transit from one computing node to the other computing node. And that has great latency and power efficiency advantages. So that's the advantage of OCS. And then for our platform, in particular, it's a nonmechanical technology. It's based on digital liquid crystal technology that is much, much higher reliability than the other solutions that are out there that are essentially mechanical-based, based on MEMS, MEMS-based solutions. And so we have very differentiated technology. We're seeing really good customer engagement and momentum here. We're really pleased to get the first customer order in our fiscal Q2. On the revenue ramp, our view remains that the revenue -- we should start to see first revenue in this current calendar year. We'll probably give better quantification of that as we move throughout the year. But I think given that we would start to see revenue this year, it would be more of a contributor in calendar '26 and '27 and beyond. And in terms of the addressable market, we'll probably talk about that more at our Investor Day in May. We'll give a better quantification of the revenue and market opportunity when we talk at our Investor Day in May. But yes, really pleased with the progress on this product.

Next question comes from the line of Simon Leopold with Raymond James.

I wanted to discuss the topic of co-package optics or CPO, given that the noise level on this has definitely increased recently. How does Coherent envision this technology affecting its business in both the intermediate term as well as the long term?

Yes. Thanks, Simon, and thanks for asking the question. And maybe to answer the question, what I'll do is I'll break it into 2 parts, let me first just talk about our view of the market evolution, how we expect the market to evolve over the coming years and co-packaged optics placed within that market evolution. And then I'll come back to the other part of your question, which is what is Coherent's opportunity within that landscape? But if I start with the first part, just on the market evolution. So first of all, we believe that the TAM for optical networking in the data center that we're going to see robust growth over the coming years and over the long term. And that's really driven by 2 things. Number one, it's just the raw bandwidth increase that's required to support the computing capacity expansion that the market is expecting. So if you look at the data center expansion plans, that drives tremendous growth in the number of computing nodes across the data center, and that drives a tremendous number of -- amount of growth in the connections between those computing nodes and the bandwidth that's required between those computing nodes. And so that alone, we think, drives a really good robust growth in data center over the long term. But the second effect that we think that we're expecting, and this is kind of where CPO plays into is we're expecting there to be a greater proportion of those interconnects between the computing nodes that switch from what are today electrical connections towards optical connections moving forward. And so think about it as the proportion of electrical versus optical, the proportion of optical connections, we believe, increases over the coming years. And the reason for that is if you…

That's great. I appreciate the thorough response. And just a very brief follow-up, please, is just wondering if there's any customer concentration or vertical concentration, you could quantify in the quarter, whether it's the amount from any 10% customers or sort of the AI consumption, whether direct or indirect to web scale. Anything you could help us with in terms of that quantification, I'd appreciate.

Yes. We have a broad range of customers, both hyperscaler customers as well as enterprise customers. The hyperscaler customers represent the vast majority of the datacom revenue, but we have multiple hyperscaler customers and are well distributed across those key hyperscalers. So yes, I would call our revenue in datacom as well diversified. And then the other point that I would make is on 800-gig transceivers, which I mentioned in the prepared remarks, is one of the really positive things that we've seen over the past year is the number of customers that are ramping 800-gig continues to expand. And so I mentioned this on our last quarter quarter's earnings update. And we saw expansion in the number of customers again over the past quarter. So we view this as very positive as our overall 800-gig revenue is very highly diversified.

The next question comes from the line of Vivek Arya with Bank of America.

This is Michael Mani on for Vivek Arya. To start, just wanted to get your thoughts on how the market landscape is evolving across VCSELs, EMLs and silicon photonics. You stated that obviously, a breadth of needs is required across these customers. But as you get closer to the 1.6T ramp, do you have a better sense of which platform might be seeing relatively more pull from these customers? And how does that inform your buy versus make decision framework around internal production?

Thanks, Michael. So first of all, maybe I'll start with kind of our strategy and philosophy around the ingredient technologies is, I think it's well recognized by our customers that when it comes to the ingredients that go into optical networking technology that Coherent certainly has the broadest and deepest portfolio of ingredient technologies. So we don't just assemble the transceiver. We bring to our customers, a very broad and deep and expansive road map in terms of all the underlying key technologies. So whether that's VCSEL laser and EML laser, a CW laser, EMLs and CWs, of course, based on indium phosphide platform, which I mentioned in the prepared remarks, silicon photonics, which we've had in production for a number of years. We're able to bring a wide array of technology. And that's one of the key competitive advantages that our customers really appreciate because when they work with us and when they partner with us in a strategic multi-generational fashion, they know they're working with a company that brings a very complete portfolio of optical networking technology. And so our approach is to invest in all those key technologies. And what we do is we work with our customers to field the particular technology that best fits their application and their needs. And so what we do is we pick out of our portfolio what we think is the most optimal technology. And so that's our approach. And that's the same approach we've taken an 800-gig, and you mentioned, you asked about 1.6T. We've taken the same approach on 1.6T as well. And then in terms of the make versus buy, I think was the last part of your question. Again, our philosophy on make versus buy is we want to make where it provides a genuine competitive advantage to our customers. And where it doesn't provide a genuine advantage, then we should be buying that or sourcing that the ecosystem. So where we invest our R&D or invest our CapEx dollars, that's where we believe we're either generating a significant technological advantage for our customers or we're creating a significant cost structure advantage. So that's where we focus and concentrate our resources Otherwise, we leverage the ecosystem. And sometimes, we mix and match as well. In the case of, for instance, EML lasers, we both source those internally, but we use external partners as well, and we have a number of really good external partners for EML lasers. So we'll sometimes use a mixture for supply chain resiliency as well. So that's kind of our overall philosophy and strategy around that.

Great. And just for my follow-up, what are the puts and takes for gross margins this year? There was nice upside this past quarter. So what initiatives worked well to deliver that and I guess, as we look throughout the rest of this year, what are some of the low-hanging fruits that you'd be able to tackle whether it's improving product costs on the transceiver side, divesting non-core assets that could help us move upwards from here?

Thank you, Michael. So when you look at the results that we achieved for Q2, the 150 basis point sequential improvement and 360 basis points year-over-year, very pleased with the results there. The elements that drove that, certainly, volume was a contributor, but we saw improvement as well on the cost side. In particular, in datacom, we continue to see improvement -- yield improvements. We saw lower cost as well as improvements in the manufacturing process that all generated improvements in gross margin. And if you recall back when we -- several quarters ago, when we put out our long-term gross margin target for greater than 40%, we talked about our gross margin expansion strategy and the elements that comprise that. Product cost or cost reductions rather are part of that, but also pricing optimization. And so those areas continue to be areas of focus for us as we drive towards the long-term model of greater than 40%. And so pleased to see the results in Q2, and we'll continue to focus on that going forward. You asked about the remainder of the year. And I guess I would really direct you to look forward to our Investor Day in May, and we'll give you more color on the various elements of our gross margin expansion strategy. and look forward to sharing that with you at that time.

And the next question comes from the line of George Notter with Jefferies.

I wanted to ask about tariffs. Obviously, there's been a lot of news on that front in the last few days and weeks. But you guys obviously have a Chinese manufacturing footprint in some areas of the business. And it does seem like the 10% tariff isn't as bad as imagined previously. But could you talk about what the effect of those tariffs would look like on Coherent? And then what sort of things could you do to mitigate those effects on the business? And then I guess the other part of this question is, is it possible that some of the strength you're seeing is a pull forward of demand customers trying to get ahead of the tariffs. But those are the questions.

Yes. Thanks, George. So on the first part of your question, obviously, dynamic situation around tariffs right now, and we continue to analyze it and make sure we're adapting as necessary. But if we look at the current quarter of fiscal Q3, we don't expect a significant impact to the current quarter results and the guidance that Sherri provided in her prepared remarks, factored in any impact that we expect from tariffs. And in the second part of your question around mitigation, I think one of the things that the company has done really well over the past years is building a very resilient supply chain. And there's been a very good strategic focus on this over the past years by the team. And they've done a really great job of that. And I think that's built a lot of resilience into our supply chain and a lot of flexibility and adaptability. And by the way, I think our customers definitely recognize that as well. Supply chain resiliency is becoming increasingly important to our customers, and they recognize that we have a very resilient supply chain. And I think within the optical networking industry, I would say it's world-class supply chain resiliency. Now I'd flag a couple of specific areas in particular that we have really great resiliency in our supply chain. One is geographic diversity in our manufacturing base. And that gives us great flexibility in terms of being able to shift the location of production to different geographies depending on the needs of our customer. And then the second thing is, which our customers appreciate is vertical integration where we've strategically chosen to invest in key technologies, which are very important from an innovation perspective or from a capacity perspective. And so that vertical integration of key enabling technologies is another source of strength in terms of our supply chain resiliency and another area that our customers really value in our overall resiliency. So we're focused on continuing to build the supply chain resiliency, but I would say we have a tremendous amount of flexibility and adaptability already built into our supply chain strategy. And then on the last part of your question, which was do we see any sort of pull forward of demand, we didn't see any indications of that. In our fiscal Q2, I would say, the data center demand materialized very much as we had expected at the beginning of the quarter. And so we didn't see any signs of any pull forward in demand.

The next question comes from the line of Meta Marshall with Morgan Stanley.

Great. Congrats on the quarter. Maybe first question, you did see improvement in lasers this quarter but had noted kind of staying kind of more cautious about that market. I just wanted to get a sense of if you could give kind of how you're viewing that maybe on telco, where you said you'll go from cautious to cautiously optimistic, just how you're viewing kind of the prospects throughout the year for that business? And then I have a follow-up.

First of all, thanks for the question. On lasers, maybe I'll address it in the context of the market. So lasers business is primarily industrial-related applications as is our materials business is a significant industrial exposure as well. And for the industrial and industrial-related markets, if we look at the submarket, from our perspective, it's just really a mixed bag in terms of the submarkets where we see some of the subsegments has seen some improvement and then others has really not seen much improvement. So overall, we continue to take in the near term, a cautious outlook on the overall industrial-related markets. We do believe that over the long term, this is a key growth area for the company. But in the short term, we're taking a more cautious view. Now that said, I will point out a couple particular subsegments that we are seeing good growth signs from the first of which is the display capital equipment, and that's where our Excimer Lasers are used for OLED screen manufacturing. And what's happening there in the end market is OLED screens are traditionally been used on smaller device screens like mobile phones are now being used larger device screens like laptops, like laptops and PCs. And so that represents a dramatic expansion in the total surface area of OLED screens and it's our Excimer Lasers that are a key enabling factor of the manufacturing of high-quality OLED screens. And so we're seeing really good growth there. We saw growth on both a sequential and year-over-year basis. And then the second area that I would flag for some improvement that we're seeing is in semi cap equipment. We're seeing stronger orders from some of our semi cap equipment customers. And those stronger orders are coming on their anticipated improved demand over the coming quarters. And so that's a positive sign as well. But overall, I would say in the near term, we're taking more of a cautious outlook.

Got it. And maybe the same on materials. I believe you guys mentioned automotive as kind of an ongoing headwind, but just as you look at some of the prospects for that business for the remainder of the year, does...

Yes. Thanks, Meta. On materials, very similar comments to lasers. A lot of the materials business is related to those same industrial end markets. So for instance, materials get used in semi cap equipment as well. So very similar outlook on kind of just cautious demand outlook around materials going into the industrial-related segments as well. And in particular, a particular area of weakness for us in materials has been around the automotive sector. And so again, here with materials taking a more cautious outlook.

The next question comes from the line of Papa Sylla with Citi.

Congrats for the strong results. My first question is maybe more for Jim. I guess, Coherent previously announced kind of seeing strong improvement on 200-gig per lane VCSEL. Just wanted to have kind of additional update on where you are in the process. And is the expectation that 200-gig per lane VCSEL could be available at some point for 1.6T cycle? Or is it more of a 3.2T story?

Yes. Thanks, Papa. So we continue to progress well on our engineering efforts around not just 200-gig VCSELs, but I also mentioned in the prepared remarks, 200-gig differential EMLs and also we're building a robust road map of CW lasers based on our indium phosphide platform as well. So again, we invest across a range of technologies and then the approach that we take is we deploy the laser technology or any other particular technology that we think is best suited for that application, whether that's a 1.6T transceiver or 3.2T or we have products on the road map beyond that as well. So I probably won't go into the details right now of what specific technology that we're selecting for any particular transceiver product just for competitive reasons. But our strategy and our approach is to build a very robust road map of ingredient technologies and pick the one that's most optimal for a particular customer application.

Got it. That's very helpful. And maybe my follow-up is around the datacom kind of margin. I believe previously, you mentioned it being mostly in line with company-level margins. But as you continue to improve yield and benefit from increasing...

Operator, did we lose Papa's line?

Yes. Papa's line has dropped.

Maybe I'll try to answer. I think I got the gist of his question. So I'll try to answer it. I think it was around data -- datacom margins. And let me step back at a broader company level, and I'll come back to datacom margins. So when I first joined the company, on the first earnings call, made it clear from my perspective that the company needed to improve its gross margins, right? And so we've been very focused on that over the past months and quarters. And on gross margin, we're approaching it from basically 2 parts, and Sherri touched on this earlier. One is pricing optimization and the other is product cost. And on product cost, I think that there's opportunity to improve product costs across the company, not just in datacom, but also in telecom and all of our industrial products, whether it's materials or lasers. I think we have a lot of work to do drive improvements on product costs. And one of -- I think Papa was asking about yields. I thought I heard him say yield at the end. But one of the key areas that we're driving improvements, for instance, in datacom margins is by improving yields. And I mentioned this on the prior earnings call a quarter ago. And so that's one of the key new product cost areas that we're focused on. There's others as well. But definitely, gross margin is a key focus area of the company. We have a lot of energy devoted to that effort right now. And I'm quite pleased with the progress that the team has made. But also, we have a lot more work to do, and we have a lot more work ahead of us, but we're very focused on that gross margin improvement goal.

The next question comes from the line of Karl Ackerman with BNP Paribas.

I have two questions, if I may. To start, Jim, is your AI transceiver opportunity this year gated by your current indium phosphide wafer capacity? I ask because some investors are contemplating how important laser wafer capacity is when you and peers discuss your transceiver road map with hyperscalers. And then I have a follow-up, please.

Yes. Thanks, Karl. So what I would first say on supply chain and capacity is, look, I want to take the opportunity to thank my supply chain and manufacturing team for doing an outstanding job of increasing capacity and supporting our customers. If you look at our data center -- datacom revenue, it grew 79% year-over-year in the most recent fiscal quarter. And I think the team has done a great job of supporting our customers. And we've been both ramping internal capacity, for instance, in datacom of the assembly of the transceivers, but also in the ingredient technologies. I mentioned -- you asked about indium phosphide. One of the things I mentioned in the prepared remarks is if you look at our fiscal Q2, on a year-over-year basis, we tripled our indium phosphide capacity. And it's our intention to continue growing indium phosphide. And U.S. government recently announced plans to help us with the expansion of indium phosphide capacity at our Sherman, Texas plant. So indium phosphide platform, which we've had in-house for over 20 years, we view as a key technology and we expect to continue to ramp volume of indium phosphide technology for EML lasers, CW lasers, et cetera. Now we do also use a multisource strategy, for instance, on EML lasers where we have good external partners as well. But we certainly are focused on continuing to ramp capacity given the demand signals that we're seeing from our customers over the long term.

Very clear. And then if I may, just on OpEx, how should we think about OpEx in March and throughout '25? I guess do you anticipate growing OpEx in line with sales growth before any restructuring some of the initiatives that you've already previously laid out but are still at the forefront?

Yes. Thank you, Karl. So from an OpEx perspective, when you look at Q2 in terms of our OpEx results there, you saw that we increased our R&D spend sequentially. And that's really as a result of our philosophy that we want to make sure that we are investing our R&D dollars for the long-term growth of the company and really those projects that have the highest ROI. So from an R&D perspective, that's what drove the sequential increase in Q2. And when you look at the midpoint of our guide for total OpEx for Q3, that's also a key driver of the increase going into Q3. From an SG&A perspective, in Q2, you saw that we actually reduced our SG&A spend, in particular, the G&A part of that. That again is part of our philosophy that we want to drive greater leverage and efficiency in the business. And so the increases in OpEx going into Q3 are really driven by R&D spend. Now on a quarterly basis, you can always see fluctuations, whether it's in terms of the timing of the benefits that we're able to achieve on the SG&A leverage front or the timing of spend of R&D programs. But that's our philosophy in terms of investing and with respect to OpEx. When you look to the rest of the year, and that really is an invitation for you to listen to our Investor Day in May as we give more perspective on our long-term model and how we're thinking about that. But that will give you -- that's just a perspective on Q3 and how to think about that.

The next question comes from the line of Thomas O'Malley with Barclays.

I have a short-term one and then a long-term one. Just briefly for the March quarter, do you think you could walk through -- obviously, revenue is flat, and it sounds like communication continues to be cautiously a bit better than you had originally expected it. But any color on just the broader segments, what gets you to that flat guidance into March is the first question?

Yes. Thanks, Thomas. It's pretty straightforward. We expect datacom and telecom to be up sequentially, and we expect the rest of our industrial-related businesses to be down sequentially and that net to the midpoint to be flat.

Got you. Super helpful. And then I just wanted to talk strategically longer term. As you look at the dynamic for the transceiver market, particularly in the datacom, are you starting to see a change in behavior from some of the hyperscalers as it relates to the domestication -- domestic -- well, I don't even know how to say the word, but the move to domestic producers of transceivers? And are you seeing changes in ordering behavior at this point? Or is that all kind of headline news and no real changes yet? I'd just love to get a feel for if you're already starting to see a move to move supply chains onshore.

Yes. Thanks, Thomas. What I would say is that I definitely believe that we have the opportunity to gain share over the coming quarters and years, and we're certainly focused on that. And when we talk with customers, almost always discussion revolves around two things. Number one, it always starts with the road map of technology and not just our transceiver road map, but the underlying ingredient technologies. And I think our customers recognize the breadth and the depth of the technology that we can bring to them. And I think that's a big competitive advantage. But I think more to your question, the second part of the discussion, which always is part of the customer discussion as well is around supply chain resiliency and the fact that we have great resiliency in both geographic diversity in the flexibility and adaptability that, that provides us as well as the vertical integration. And they see that supply chain resiliency as a tremendous advantage. And so that's another benefit beyond just our raw technology road map. And so I would say that both of those are very much appreciated by our -- certainly by our big strategic customers.

The next question comes from the line of Christopher Rolland with Susquehanna International Group.

This one is for Jim. And Jim, you're a bigger picture thinker so this is a bigger picture question, I think. It's really around networking intensity and also timing of either the peak in 800G or the beginning of 1.6T. And there's kind of 2 parts. The first part is DeepSeek, obviously, all the connectivity guys were down big, that Monday. Do you think that impacts connectivity at all, the outlook for it? And then perhaps there are pushouts of key AI products? Do you see that affecting either 800G or 1.6T for you guys this year?

Yes. Thanks, Chris. So on the first part of the question around DeepSeek and the outlook, I'll first of all say that we've seen no significant changes in our customers' outlook, both in terms of the orders that they're placing or the long-term forecast that they have been providing to us. We've seen no significant change there. And I would say in terms of longer term, I think we share the view that many others do in the industry, which is that to the extent that any technology, whether it's DeepSeek or any other technology, makes AI more pervasive that propagates AI in a wider way, makes it easier to adopt or cheaper to adopt, we view that as underlying -- as providing underlying growth for the market over the long term. So we view that as a long-term positive market trend. But in the shorter term, we've seen no significant change in customer forecast or ordering patterns. And because of that, I also don't see any impact that it has on 800-gig peak or 1.6T ramp. I believe it will have any effect on that. And just more specifically on that part, we believe 800-gig would continue to grow over the coming quarters even as 1.6T is introduced, because if you look at the customers, actually, the customers, it really depends on the customer around what specific data rate they're currently on. We still have a number of customers that are primarily on 400-gig and still have yet to transition to 800-gig. And we have customers that are just at the beginning of their 800-gig ramp. So I think it's 800-gig continues to grow while we start to ramp 1.6T.

Excellent. And then secondly, there are a bunch of Chinese guys with really big capacity ramps coming. I'm just wondering if you're seeing anything in terms of transceiver pricing, pressure on your own gross margins in this area? And how much more cost cutting there is to do on the gross margin side on -- or efficiencies on transceiver as well?

Thanks, Chris. I would call the transceiver pricing that we've seen as pretty stable. I don't end as predicted as we would expect. I don't think there's been any unusual pricing changes that we've seen. And then on the second part of the question around gross margin efficiency, and I kind of addressed that a little bit earlier in the questions around at a company level, I think we have a lot more work to do on driving product cost efficiency in our gross margin line. So a lot more work ahead of us, and that includes for transceivers as well. I think there's improvements that are still in front of us in terms of improving product cost structures, yield being one of them, but I think input costs are an opportunity for us as well. So yes, a lot more work to do. Good progress, and I appreciate the progress from the team in fiscal Q2, but both Sherri and I are not yet satisfied with the gross margin, and we continue to make sure the company is focused on it.

The next question comes from the line of Jack Egan with Charter Equity Research.

I was hoping you could talk about the yield improvements in datacom a bit. So I was wondering where exactly it came from, like whether it was materials or on the manufacturing or back-end side. And then are they coming from kind of the typical development process where you can just continually squeeze out improvements? Or have these been more like discrete onetime improvements?

I would say it's a range of things, right? There's a number of different places that we're focused on yields. I would say, some of them are onetime improvements. Some of them are things that we believe are ongoing improvements that we're sort of at the start of ongoing improvement. I think it's a range of things. We're certainly looking at the entire expanse of any yield improvements we can drive. But also, as I mentioned just a minute or 2 ago, we're definitely looking at input costs, on overhead costs, anywhere where we can drive cost efficiency, we're focused on that. So I think it's a range of activities.

Yes. I would just add that just a reminder that from Q1 -- going into Q1, we saw improvements in yield as well, and we continue to see that in Q2. So as Jim mentioned, it's in different areas, different parts of the process, but we're focused on all those areas, and we're really pleased to see continued yield improvement in Q2 in the datacom business.

Great. And so for my follow-up then, you've given a lot of color on your strategy from the product portfolio and efficiency standpoint. And I know you'll probably share more on this during the Investor Day, but have you made or are you looking to make any major changes when it comes to kind of the sales and marketing or the distribution side, I mean, because Coherent has the very broad footprint with vertical integration, as you mentioned. So I was just curious if there were any synergies there.

Yes. Thank you. So that is another area that we've been driving improvement in what I would say is kind of similar to the activities we were driving in R&D is we're trying to make sure that, first of all, the resources around sales and marketing are applied in the area of greatest opportunity. And so we have made changes where we've reduced resources and -- sales resources in some areas, and we've increased resources in other areas. And so we are shifting resources to where we believe is the greatest long-term growth opportunity and margin growth opportunity for the company. And so yes, we are -- there's a number of changes we've already driven and that's some place where we'll continue to drive improvements moving forward.

Thank you. We have reached the end of our time for Q&A. I'd now like to turn the floor back to CEO, Jim Anderson, for closing comments.

Yes. Thank you, operator, and thanks, everybody, for joining us on the call today. So as we wrap up here, I first of all want to thank all of my Coherent teammates for the great hard work and the dedication and the really good solid execution in our fiscal Q2. And thanks for everybody on the call today. Thanks for your support and looking forward to continuing to update you on our progress. Operator, that concludes our call.

Thank you. This concludes today's conference. You may now disconnect your lines at this time. And enjoy the rest of your day.
