Let me now turn the call over to our CEO, Jim Anderson. Thank you, Paul, and thank you everyone for joining today's call.

You unmarked a strong start to fiscal 2027, revenue increased 16% sequentially and 56% year over year on a pro forma basis, non-gap EPS increased 80% year over year, reflecting continued gross margin expansion and operating leverage. Strong customer demand and our rapid capacity expansion are supporting this growth with near-term bookings and newly signed LTA's providing multi-year visibility. We remain on track to achieve our first $3 billion revenue quarter by the end of fiscal 27. We expect the full year pro forma revenue growth rate to exceed 60%, more than double our fiscal 26 pro forma growth rate.

We also have a clear line of sight to our first $4 billion revenue quarter in fiscal 28. Coherent is a photonics platform company bringing together technologies across the optical signal chain from materials and components through subsystems and complete solutions. Our breath positions us to support customers across data center and communications networks. We're at the center of an extraordinary expansion in optical networking infrastructure, driven by rapid AI growth, the transition from copper to optical connectivity, and rising demand for bandwidth and energy efficiency across increasingly large and complex data center architectures.

Our established businesses continue to grow rapidly, with data center revenue up 85% year over year in Q1. At the same time, new growth areas are ramping as well. For example, scale across data center interconnect revenue is growing rapidly, with Q1 revenue roughly quadrupling year over year and reaching a nearly $1 billion annualized revenue run rate. In addition, photon link are newly announced integrated optics platform is also beginning to ramp, and we expect photon link revenue to exceed $100 billion in our march quarter.

Accelerating revenue growth continued gross margin expansion and operating leverage position us to grow profitability faster than revenue. We expect fiscal 27 to be an exceptional year for coherent. Moving to our data center and communications segment, revenue increased 21% sequentially and 79% year over year marking a fourth consecutive quarter of accelerating growth on both a sequential and year over year basis. The segment now accounts for 82% of coherence total revenue. Near term demand remains strong, and our visibility into long term demand continues to improve.

Order coverage through calendar 27 is exceptional, and customer orders increasingly extend in the calendar 28. We signed multiple new LTA's in Q1, and customer LTA's typically extend through the end of the decade. We continue to see no signs of attenuation in demand. Within the segment, data center revenue increased 17% sequentially and 85% year over year marking our fourth consecutive quarter of double-digit sequential growth. We expect another quarter of strong sequential and year over year growth in the current quarter.

In data center transceivers, we're ramping 1.60 products with multiple customers while continuing to grow 800 gig revenue. We expect strong transceiver revenue growth in Q2 driven by both 1.60 and 800 gig. We expect 1.60 revenue to continue ramping rapidly over the coming quarters, while 800 gig revenue continues to grow through calendar 27. At ECOC in September, we demonstrated our progress beyond 1.60 with a 3.2T OSFP pluggable transceiver built with our 400 gig differential emails and photo diodes.

We expect pluggable transceivers to remain the dominant form factor for scale out networks over the coming years. Coherence is helping shape the industry ecosystem for emerging formats, demonstrating XPO at OFC, and also supporting the new USFP form factor. Turning to OCS, customer engagement is broadening across scale-across and scale-out and scale-up networks, spanning our 320 by 320 platform and denser configurations. We're expanding production at two sites to meet demand. As capacity ramps, we expect OCS to become an increasingly meaningful contributor to revenue growth and margin expansion.

At ECOC in September, we launched PhotonLink, our new platform for integrated optics. It's designed to address the transition from copper to optical connectivity in AI data centers, creating a significant opportunity for coherent. We estimate that CPO, NPO, and chip-to-chip optical interconnects represent approximately $30 billion of market opportunity by 2030, bringing our total market opportunity for data centering communications to about $90 billion in 2030. PhotonLink brings together coherence photonic technologies and manufacturing capabilities in an N10 platform that spans the optical signal chain, from generating and shaping light through transmission and detection, to converting the signal to electrical form.

The platform is designed for a wide range of architectures and applications, including CPO and NPO, scale-out and scale-out networks, and scale-in chip-to-chip links. It includes lasers, laser modules, complex fiber assemblies, and other optical components, and supports Indian FOSFITE-based CW lasers and VIXL-based technologies. We believe this breadth and depth differentiates us. For an XPU or switch chip with 100 terabits per second to bandwidth, we estimate our content opportunity can reach approximately $15,000 per chip. Customer engagement is validating the opportunity.

In Q1 we signed another significant PhotonLink LTA with a major AI company. The total revenue value of this new LTA is approximately $20 billion over five years, with revenue beginning to ramp in early calendar 28. This is in addition to our previously announced LTA with NVIDIA. Beyond these two anchor customers, we have more than 10 additional CPO engagements, more than 10 NPO engagements, and more than five chip-to-chip engagements. We expect PhotonLink revenue to ramp quickly over the coming quarters.

We expect revenue to exceed $100 million in our March quarter and to exceed $250 million per quarter before the end of calendar 27. Expected shipments in the current quarter include a range of CPO products, including our ultra-high power 400 milliwatts CW laser, our fiber assembly solutions, and other products. PhotonLink is initially being deployed in CPO scale-out applications. We expect to begin shipping PhotonLink products for CPO and NPO scale-up applications in the second half of calendar 27.

Over time, we expect PhotonLink to become a multi-billion dollar product line for Coherent. Expanding our Indian Fosified capacity is a key enabler of growth in both Indian Fosified Plugable Transceivers and Indian Fosified-enabled PhotonLink solutions. Our six-inch Indian Fosified expansion is progressing well. We doubled our internal Indian Fosified output capacity year over year in Q1, one quarter ahead of our original plan. Q1 was our highest production quarter ever for EMLs, including both 100 gig and 200 gig devices.

The ramp contributed meaningfully to data-centered growth, and we expect it to remain an important driver of revenue and gross margin. Most of the gross margin benefit of our Indian Fosified expansion is still ahead of us. As the expansion will enable us to increase our mix of internally sourced Indian Fosified components, which have a tremendous cost advantage. We remain in track to more than double our internal Indian Fosified output capacity again by the end of calendar 27.

We've secured the substrates and other critical inputs needed to support this ramp, and given the strength of customer demand, our planning additional capacity expansion beyond 2027. Our six-inch lines in Texas since we've been producing EMLs, CW lasers, and high-speed photo diodes, with yields that continue to exceed those of our three-inch lines. Production includes our 400 milliwatt CW laser for CPO, which is covered by our NVIDIA partnership, and is expected to begin generating revenue this quarter. We also remain on track to begin six-inch Indian Fosified production in Zurich in the first half of calendar 27, further extending what we believe is a meaningful manufacturing advantage.

Moving to communications, revenue increased 34% sequentially, and 84% Euro a year, and we expect another quarter of strong sequential in Euro a year growth in the current quarter. Traditional telecom continued to grow, but the primary growth driver was scale across, which has quickly become the largest source of revenue within communications. Over the past year, we've expanded our data center interconnect portfolio to help customers connect data centers with greater capacity and efficiency. Building on our leadership and pump lasers in our broad component portfolio, we've introduced higher-level products, including modules, line cards, subsystems, and our new multi-rail solution.

These offerings are seen strong customer demand, and help customers make better use of existing fiber while scaling high-capacity links between distributed AI data centers. In Q1, scale across revenue exceeded $200 million, up 53% sequentially, and nearly four-fold year-over-year. That puts the business at a nearly $1 billion annualized revenue rate, making it one of our fastest growing businesses. With multi-rail beginning to ramp in our March quarter, we expect quarterly scale-cost revenue to roughly double from the Q1 level by the end of calendar 27.

Turning to industrial, Q1 revenue is flat sequentially and year-over-year on a pro forma basis. Bookings were strong led by semiconductor capital equipment customers, and we expect growth to resume in the current quarter. Near-term growth is being driven by semiconductor capital equipment, AI infrastructure, and fusion energy. In semiconductor equipment, our lasers, precision optics, and engineered materials serve front-end applications, and we've seen a strong uptick in bookings. In AI infrastructure, our CO2 lasers and zinc-cellinide optics are used to drill advanced circuit boards for AI servers.

Demand is also growing for our pulsed laser deposition systems, used to produce high-temperature superconductor tape for magnetic fusion. Over the longer term, we see significant opportunities in data center XPU cooling and quantum technologies. For AI data centers, our thermodyte material can enable higher XPU performance and token generation. We're shipping prototypes to several strategic customers this quarter, and we expect revenue to begin ramping in the second half of calendar 27. In quantum, we supply lasers and materials to leading quantum technology developers and are engaged in next-generation programs.

Given the multiple growth areas, we expect our industrial segment to return to growth and build momentum over the coming quarters. In summary, Q1 demonstrated the strength of our growth momentum and the breadth of our opportunity. Demand remains strong, customer commitments continue to deepen our visibility, and we are expanding capacity ahead of plan. Established businesses continue to grow rapidly, while new growth areas are ramping quickly. Our focus is on execution, expanding capacity, delivering for our customers, and improving profitability as we grow.

We believe this combination positions coherent for sustained growth in fiscal '27 and beyond. I want to thank our team for their outstanding work this quarter. I'll now turn the call over to Sherry. Thank you, Jim. I'm extremely pleased with the outstanding Q1 financial results. Our performance in the first quarter represents a powerful continuation of our growth trajectory, characterized by accelerating top-line momentum, durable structural growth margin expansion, and significant operating leverage. The compounding impact of these operational drivers fuels non-gap EPS growth to significantly outpace revenue growth.

We achieved this strong performance while preserving balance sheet flexibility and strategically directing capital toward targeted capacity expansions and making investments in our product roadmap to support robust AI data center and communications demand. Let me now provide a summary of our results. First quarter revenue with a record 2.37 billion, representing a sequential acceleration of 16% and a substantial 50% increase year over year. This performance was driven by the continued AI infrastructure build-out across our data center and communications businesses.

On a pro-forma basis, excluding the financial impact of the aerospace and defense business and the Munich-Germany product division, both of which were divested in 2026, revenue increased 16% sequentially and 56% year over year. Our non-gap growth margin for the first quarter was 40.6%, representing a 37 basis point increase sequentially and a 184 basis point improvement as compared to the year ago quarter. This continuous expansion reflects durable pricing optimization and structural cost improvements, particularly within our data center and communications segment.

The improvements in growth margin both sequentially and year over year were driven primarily by pricing optimization, lower product input costs, and improved manufacturing yields. We have made significant progress with our pricing optimization strategy to ensure that we price our highly differentiated products for the value they provide to our customers. Our growth margin profile is also benefiting from the transition to six-inch Indian boss fight as we continue to scale our production capacity. Given the progress that we have made over the past couple of years and our current trajectory, it is clear that we need to raise our growth margin target.

We now expect to achieve our first quarter with growth margin above 45% before the end of calendar 2028. We believe the drivers of this growth margin expansion are continued pricing optimization, ramp of new growth platforms, full operational leverage of our six-inch Indian fossified capacity, and other cost improvements. I also want to note that the new over 45% target is 300 basis points higher than the long-term target we provided to the investment community only 18 months ago.

This quarter non-gap operating expense was 412 million compared to 377 million in Q4 and 304 million in the year ago quarter. Non-gap operating expenses as a percentage of revenue decreased meaningfully to 17.4% down from 18.4% in the prior quarter and 19.2% in the year ago quarter. This improvement reflects enhanced operational discipline and underscores the powerful operating leverage inherent in our business. From an R&D perspective, we are strategically directing our capital toward high conviction long-term growth drivers which Jim outlined in his remarks.

This disciplined approach ensures our investments are concentrated where they generate the highest financial returns and drive sustainable revenue growth. Our first quarter non-gap operating margin increased to 23.2% from 21.8% in the prior quarter and 19.5% in the year ago quarter. The sequential and year-over-year increases were driven by strong revenue growth, expanding growth margin, and structural expense discipline. First quarter non-gap earnings per diluted share was $2.09 of 20% from the prior quarter and up 80% from the year ago quarter.

Earnings growth continued to exceed revenue growth demonstrating growth margin expansion and operational leverage accelerating our bottom line profitability. Turning to the balance sheet, we close the quarter with a healthy cash balance of $2.34 billion compared to $2.59 billion at the end of the prior quarter and $1.55 billion at the end of the year ago quarter. Our debt leverage ratio at the end of Q1 was 1.1 times as we continued to maintain a highly resilient and flexible balance sheet.

Consistent with our capital allocation priorities, we strategically invested in opportunities that will drive long-term growth and profitability. Capital expenditures for the first quarter increased sequentially to $776 million, up from $556 million in the prior quarter and $104 million in the year ago quarter. These investments directly support the future growth of our data center and communications businesses with excellent financial returns. Our conviction to deploy this capital at an accelerated rate is backed by exceptional customer visibility, a robust pipeline of committed purchase orders and additional multi-year supply agreements.

Furthermore, this capacity offers significant fungibility as our infrastructure can be efficiently repurposed to support multiple product lines. Given the strong visibility and record backlog, we expect capital expenditures to increase sequentially again in the second quarter. With our strong balance sheet and profitability trajectory, we possess a scale and flexibility to continue investing capital toward high ROI growth initiatives while supporting customer demand. I will now turn to our guidance for the second quarter of fiscal 2027. We expect revenue to be between $2.55 billion and $2.75 billion.

We expect non-gap growth margin to be between 40% and 42%. We expect total operating expenses of between $430 million and $450 million on a non-gap basis. We expect a tax rate for the quarter to be between 18% and 20% on a non-gap basis. We expect non-gap diluted EPS to be between $2.28 and $2.48. In summary, fiscal 2027 is off to a powerful start with strong financial momentum backed by deep demand visibility. Our focus remains on rapidly ramping capacity to meet demand, expanding our growth margin, capitalizing on the immense operating leverage in our model, and executing a disciplined capital allocation strategy focused on maximizing returns that drive long-term shareholder value.

That concludes my formal comments. Senator, please open the line for the Q&A session. We will now begin the question and answer session. To ask a question, you may press star than one on your touch-tone phone. If you are using a speaker phone, please pick up your handset before pressing any keys. If at any time your question has been addressed and you would like to withdraw your question, please press star than two. At this time, we will pause momentarily to assemble our roster.

The first question today comes from Joseph Cardoso with JP Morgan. Please go ahead. Hi, good afternoon, and thank you for the questions here. I really appreciate some of the disclosures that you provided this quarter and wanted to first start with Botan Link and the initial visibility you provided there. I was hoping you could provide more color with respect to the ramp itself, especially just given the backdrop of the $20 billion agreement that you've highlighted. I have a follow-up.

Thank you. Yeah, thanks, Joe. First of all, we are certainly really pleased with the momentum that we have around Botan Link. Whether you measure by customer engagement or LTA's, as you mentioned, or just the revenue outlook that I mentioned in the prepared remarks, we are just really pleased with the progress there. As a reminder, Botan Link is, we consider it a one-stop shop for integrated optics. It's basically our platform for allowing customers to basically have a platform that allows for the optical link from end-to-end.

It's the complete optical signal chain and all the optical technology along that path. I'm really excited about the progress. As I mentioned in the prepared remarks, over 20 customer engagements on CPO, over 10 on CPO, over 10 on NPO, and then over five chip-to-chip engagements. The customer engagements are very extensive and they continue to grow. You mentioned or asked about the LTA, really pleased about that. Major AI customer and that LTA is, as I said, $20 billion over a five-year period.

The revenue for that would start at the beginning of calendar 28. But the Botan Link revenue ramp is starting ahead of that. We'll ship a little bit of a small amount of Botan Link revenue this quarter, but we expect to ship over $100 million in our March quarter and then before the end of calendar 25, expect to ship over $250 million in a quarter. I'm really pleased with all of that progress. I guess the other thing that I would add is, if we look further out, we're expecting this over time to become a multi-billion dollar product line.

The initial shipments of Botan Link are all around CPO in the scale out network, but when we start to ship into CPO and MPO into scale up networks, I think that drives another huge leg of demand for this technology. I think that will be the much bigger adoption that we see. That we expect to ship revenue into CPO and MPO applications in the scale up domain towards the end of calendar 27. We're excited about the progress and expect this to become a major product line for us.

Thank you for that, Jim. Maybe in a similar vein, I wanted to touch on the scale across ECI opportunity. Particularly curious how we should think about the customers and products that are underpinning the revenue outlook to double by the end of the next calendar year. Thanks again. This has been a really great growth area for us over the past year. In fact, it surprised us a little bit how quickly this has grown. So overall, the DCI and scale across that falls within our communications part of our business, which is essentially everything outside of all communications outside of the data center.

If we look at that segment overall, communications grew 84% year over year, but while telecom grew, the vast majority of that growth was driven by DCI. So what's going on there is you're seeing these large AI workloads that are spanning multiple data centers. So that's driving the need for much greater bandwidth and connectivity, optical connectivity between data centers. So that's what's driving. That's the underlying market dynamic that's driving the growth. Then you asked about customers and products.

So customers would be either equipment makers or certainly selling into multiple different equipment makers that whose equipment goes into scale across applications, but also selling directly to hyperscalers as well. And so it's a mixture of both types of customers. And then the products, it's interesting, in this part of the market, we sell products at multiple levels of the value chain. So we sell in components, like for instance, pump lasers that go into a wide range of different equipment.

One level up in the value chain, we sell subsystems and modules. So ZRZ or plus modules, line cards, amplifiers, rotums, et cetera. And then one level up from that, in some cases, sell complete solutions to our customers as well. So we're selling across multiple levels of the value chain. And so I think that's helped us really maximize the growth here as well. And as I mentioned in the prepared remarks, if we look at our Q1 revenue, it was over 200 billion.

So we're basically at about a billion dollar annualized revenue run rate now. And that's that Q1 growth that quadrupled year over year. And we expect that if you take that Q1 baseline, we expect that the revenue to double again before the end of calendar 27. And so that growth that we've seen to date, that's ahead of multi-rail. So we expect multi-rail revenue, which is a multi-rail is a great solution, some great technology that we have there.

We expect that to start that revenue to start to ramp in our March quarter. And so it's been a really good area of growth. And we expect this to continue to be a very good area of growth over the coming quarters as well. Thank you, Jim. Appreciate all the color. Thanks, Joel. The next question comes from Simon Leopold with Raymond James. Please go ahead. Thanks for taking a question. First, Jim, I want to thank you for the increased transparency on slide 7.

I know this is something I've been probably annoying you about. So thank you. The slide did not mention OCS. I know you talked about the product group in your prepared remarks, but could you update us on your progress and expectation for this product group? And then I've got a follow-up, please. Yeah, sure. Thanks, Simon. Thanks for the feedback, as always. We're always looking to improve. So I appreciate the feedback. But, yeah, in OCS, I did mention in the prepared remarks, OCS falls within our data center part of our business, and just reiterating data center was up 85% year over year in our Q1.

OCS continue to make good progress. We've got really extensive customer engagement. We've seen that customer engagement continue to expand across more applications, and not just scale out to applications, but scale across and scale up applications as well. And that's across, in terms of products, that's across both 320 by 320 systems, which are shipping, as well as denser configurations. I think the denser configurations will be used more in the scale up applications. We're ramping production at two different sites in parallel, and that's really to meet the demand that we're seeing.

We have a very differentiated technology. It's liquid crystal. It's non mechanical technology, has better power efficiency, and better reliability than MEMS-based solutions. So we feel really well positioned. We're ramping production, and I think it will be an increasingly larger contributor to our revenue growth in the quarters to come. And maybe the last thing that is we see the market opportunity for OCS as at least $4 billion by 2030. It could be larger than that. Thanks. And as a follow-up, I have a hard question, one that I imagine you anticipate getting, is what does the proposed consolidation of Lamentum and Marvell mean to you?

Thank you. Yeah, thanks, Simon. No, I don't think that's a hard question at all. I think happy to answer that. I'd give a few thoughts on this. I think number one is it definitely demonstrates that optics and photonics is becoming an absolutely critical part of data center architecture. You know, as we look forward, as we convert the entire scale-up network and then even the scale-in chip-to-chip communication links, over time all of that getting converted from copper to optical, photonic technology is absolutely critical to making that happen, to driving the innovation in data center architecture.

So I think it's a proof point around just the criticality of optics and photonics. And then I think for coherent, I think it highlights the tremendous strategic value of the portfolio that is within coherent. There's no other company, I believe, on the planet that has a broader and deeper set of photonic and optical technology. If you look at the entire optical signal chain from the generation of the light to the transmission through our fiber optic cable that we make to detection on the other side, I don't think there's any other company that's got a better portfolio of technology.

So I think it definitely highlights the strategic importance of our technology platform. And then look, I think from a customer perspective, I think that I think a lot of, for a lot of our customers, our customers, I think it's really important that they have an independent photonic optical supplier and partner. And so I think it positions us really well to be that independent optical supplier that's going to support, without any competitive conflict, can support multiple different customers and support both hyperscalar customers, can support semiconductor customers.

And so I think it positions us really well to be that partner of choice in terms of optics for the industry. So look, we think we're really well positioned from both a technology standpoint, manufacturing standpoint, and strategically. And I think we're on a really great growth trajectory. And I think you can see some of that already in the photon link technology and the photon link revenue ramp. Thank you. The next question comes from Tom O'Malley with Barclays.

Please go ahead. Hey guys, thanks for taking my question. Thanks for the additional color as well. I guess the first part of the question for you, Jim, is why now in terms of giving the longer-term forecast, it's been something that you've kind of held off on during for a while. You get $3 billion and then $4 billion next year. And then the second part of the question is, is that all backed with supply? How are you able to get visibility that far out?

Is that already in the books today? Or perhaps you can give us like what percentage of that is backed with supply today? Or if you need to add any to get you to those numbers? Yeah, thanks, Tom. I think it is a little bit different. We are providing a little bit longer-term visibility than we normally would. I think it's really backed by the just extraordinary level of visibility that we have on the business. And when I look at the backlog, the bookings, so both near-term visibility and long-term visibility, if I look at just the backlog that we have, I mean, calendar 27 is basically booked out and the customers are booking out calendar 28 now.

So from a near-term booking demand perspective, we have great visibility. We've signed a number of new LTA's over the past quarter. I mentioned one of the big LTA's as part of the photon link prepared remarks, but the LTA's also give us really good visibility because they include very high-quality forecasts, long-term forecasts. So I think that's given that really good visibility, that's certainly giving us confidence. And then also, great that you mentioned supply. We've done a number of things within our supply base to make sure that we've got the right supply in place to support that as well.

So yeah, I would say that those views that we gave, whether it's the $3 billion this year and the $4 billion quarter next year, is underpinned by supply agreements. Also, remember that we're highly vertically integrated. So a lot of that's underpinned by our own internal supply that we're ramping, right? One of the constraints if we look back over the past year, year and a half, one of the constraints has been indium-phosphide. And I'm just really pleased with how the team has executed very, very well on the indium-phosphide production ramp.

We've doubled production capacity a quarter earlier than what we thought we would, and that gives me the confidence that they're going to achieve, the team's going to achieve our plan to more than double capacity again by the end of calendar 27. So you put all that together and you're feeling really good about outlook and the visibility for the business. Super helpful. And then just as my follow-up for that LCA, obviously $20 billion a pretty robust number over that five years.

Could you just give us any color just around that customer perhaps? And then if you can't talk about the customer around some of the solutions that obviously the photon link so it spans a large number of your products, but any more specificity would be really helpful just given the size of that customer. Yeah, sure. So definitely a leading AI data center customer name where you would definitely recognize, right? And so we're really proud of that partnership excited about it.

That's all that LTA for $20 billion is all around photon link technology. I would call it, I would say it's anchored by our laser, our 400 milliwatt CW laser. That's kind of the anchor of that LTA, but there's it's more than we're selling more than just that laser. So we're selling more, you know, call it a higher level solution than that. So more than just that laser. So we're really, really pleased by that. As I mentioned, the revenue, we expect the revenue to start to flow from that in early 2028 and to ramp over the course the quarters of years after that.

And so I'm really pleased with that. And I think given the engagement that we have on photon link across many different customers, many different solutions, we certainly expect to sign more long term agreements and partnerships with photon link over the coming quarters as well. Thanks a lot, Jim. The next question comes from George Nader with Wolf Research. Please go ahead. Hi guys, thanks a lot. I guess I just wanted to ask you a question about the 45% gross margin.

Outlook before the end of the 28. So I guess I'm curious, like what does that assume about your transceiver business? I'm just wondering if to hit that you need to gate your transceiver supply or transceiver ramp or is this just a case where everything can ramp in units and naturally would ramp and you wind up in 45% gross margins? What's with you there? Thanks. Yeah, thanks, George. I'll start and then see if Sherry has any color to add.

But yeah, we haven't assumed that we're kind of artificially gating the transceiver business. So there's no assumption on that. We're assuming that the transceiver business grows at what we think is a reasonable growth rate to expect from the transceiver business. But on top of that, we do have new products to our ramping on top of that. Photon link, number of new products in data center interconnect, OCS ramping over time as well. And so you put all those products ramping over time and those products are are accretive to the company's margin.

I think the new product ramp helps as well. And then in addition to that, the other thing that I would add more on the cost side is number of different cost activities that we're driving. But certainly a big one of it is we expect additional leverage in terms of gross margin from our Indian Fosified ramp. I think there's, as I mentioned briefly in the prepared remarks, I think most of the benefit from Indian Fosified expansion is still ahead of us.

And so I think there's a good component of the margin expansion that's kind of underpinned by the Indian Fosified expansion as well. Is it possible to get the company to hire margins than 45% over time? I mean, I guess I'm maybe looking at momentum as an example. This guy's obviously has had quite a bit of margin expansion. Obviously, the fastest growing parts of that business are many of the areas where you're kind of looking for growth going forward.

Is 45% just a stop in a bigger picture or a bigger number? What do you think? I don't think there's any structural barrier to us driving gross margin above 40%. In fact, I think Sherry, in her remarks, I think she said over 45% before the end of calendar 28, I think, is the way she said it. We certainly don't view, just like our old target of 42%, where we said over 42%, we never viewed that as a stopping point.

We viewed that as a stop along the way, and I would say 45% is a stop along the way, and I don't see any structural reason why the company couldn't continue to drive gross margins beyond that. We just add that the target that we put out about 18 months ago at our investor day of over 42%. That was a three to four-year target that we put out, but we pulled that in, and only 18 months now raising our target to over 45%.

As we get close to that target, we'll certainly evaluate and look at what makes sense beyond that, but it's just a stop along the way. George, maybe the other thing I'd add is we're certainly super focused on gross margin expansion, but the other thing that we're very focused on is operating leverage. I think we're quite pleased to see that we're gaining operating leverage in terms of OPEX as a percentage of sales, and we expect that to continue as well, so I think you should expect continued operating leverage as well.

Thank you. The next question comes from Gianmarco Conti with Deutsche Bank. Please go ahead. Yeah, great. Thank you for taking my questions. Congrats on the poster. Maybe starting with PhotonLink. I wanted to touch on the scaling/scalap opportunity with MicroVxel. You mentioned you had five engagements, I believe, chip to chip. I'm curious if you could talk a little bit more detail here, whether there is anything you can quantify in terms of revenue to come online next year, anything around MicroVxel?

Thank you. Yeah, so thanks for asking about MicroVxel. So certainly when I look across the PhotonLink engagements, there is, I would say, many VIXel MicroVxel. We call it multi-core VIXel because the multi-core VIXel attaches to our multi-core fiber that we produce. But multiple of those engagements involve our VIXel technology. I mean, maybe just as a reminder of the company's sort of depth in VIXel technology. Number one is, we've shipped over 700 million VIXels into data center applications over the past year.

So we have enormous manufacturing expertise in VIXels. Also at the ECOC conference when we launched PhotonLink, we talked about our technology in VIXels, MicroVxels, VIXel arrays, etc. You know, we showed that one of the things that we showed was that we had industry leading energy efficiency around VIXels. We showed one pico-joule per bit capability, which I think is very industry leading capability. And so VIXel is definitely a core technology, something that the company has a long history in, and we have multiple engagements.

I think you'll see that deployed in NPO applications relatively in scale-up NPO applications in relatively short amount of time. I think you also asked about scale-in chip-to-chip. I think that's a little further out in time. I think PhotonLink in scale-in applications is more in the 2029 to 2030, but we'll definitely see, I think, VIXels deployed in NPO applications well before that. If I could just ask a follow-up. It's been a tough question, sorry to put it in the spot, but I've been receiving a lot of questions from investors around Chinese later suppliers.

I was wondering if you could provide any kind of thoughts on basically more supply coming in online, and whether you see them competing for ultra-high-powered lasers for CWs? Yeah, so I don't see that those competitors in terms of ultra-high power. If you're talking about the 400 milliwatt CW laser, we're not seeing competition from really only of one competitor there as far as we can see, right? We're really not seeing any other competitors out there with high-power CW laser capability.

Thank you. Operator, before we go to the next analyst, if we could ask all the other analysts to limit themselves to one question, were the goal of trying to accommodate everybody on the call? All right, thank you. The next question comes from Dan Shoe with Berenstein. Please go ahead. Hey, thanks for the question. You mentioned that scale-up optics should start towards the end of calendar 2027. Anything you can share about whether the initial deployments are MPO or CPO, and also about how this is primarily going to become vixels, or will this start with IMP-based lasers?

Yeah, thanks Dan. So I think what we'll see, we'll definitely see CPO in scale-up. We certainly believe that. I think we'll see MPO scale-up soon after that as well. If not by the end of calendar 27, I think we'll certainly see deployment in the early part of 28. So I think in scale-up, both CPO and MPO within either that late 27 or early 28 time frame in the scale-up applications. And then I think, did you ask, what was the second part of your question, Dan?

Vixel. How much of it is Vixel versus IMP? Yeah, I think the initial deployment is Indian Postified, the Hyper-CW lasers. That's for CPO in both initially scale-out and then in scale-up. And then I think Vixels will happen in that NPO kind of early 28 time frame. Got it, thank you. The next question comes from Ryan Kuntz with Needham. Please go ahead. This is Jeff Oppson on for Ryan. Thank you for the question. You noted ramping the Indian Postified supply for your own laser supply and that'd be able to lead to the margin expansion from weaning off external sources.

I was just curious if there's any color on what the split is currently versus internal versus external and the timeline of that over time as it relates to the margin expansion. Thank you. Yeah, thanks, Jeff. We haven't broken out the split, but I can tell you the split hasn't changed much in a year. We're using about the same mix of internal versus external now as we were a year ago. So although we've doubled our internal Indian Postified supply, the primary usage of our internal Indian Postified parts is in our data center transceivers.

And if you look at the growth rate of our data center business, data center transceivers, it's basically tracked the growth of our Indian Postified capacity, although basically one quarter later, because when in the quarter we produce the lasers, the next quarter is when we ship the transceivers. And so essentially our transceivers have been businesses grown at the same rate as our internal Indian Postified, which means that our mix of internal versus external really hasn't changed much over the past year.

Now, as we continue to expand Indian Postified now looking forward, more than doubling it by the end of 27, we do believe over the coming quarters we'll start to shift more of the mix from external towards internal. Now, we always believe we'll have some portion of our supply from external for our transceivers business, but we believe over the coming quarters we'll start to shift more towards internal. And that's really because it's a tremendous cost advantage for us to use our internally produced lasers, especially the ones that are made on the 6-inch platform.

And in my prepared remarks when I said the majority of the benefit from 6-inch Indian Postified is ahead of us, that's actually what really what I'm referring to is that benefit of changing the mix towards internal is largely ahead of us. And that's a much bigger cost structure improvement. Alex, thank you very much. The next question comes from Papa Celia with Citi. Please go ahead. Thank you. Thank you for taking my question and congrats on the very impressive results.

Jim, I wanted to maybe double click on the $15,000 of content per, I think, 100 people teach if you mentioned earlier and at ECOC. So, assuming that is probably the full stack opportunity, which might be a longer term figure, but I thought you would be helpful to also have a sense even qualitatively on what percentage, I guess, of that 15,000 you expect to capture in the near term, this is longer term, and how they may change beyond 27.

Yeah, thanks, Papa. The 15,000 basically represents if you take an example of a chip that needed 100 terabit of I/O. And if you were using our full photon link portfolio, which would include not just the lasers, but all the other components, isolators, thermoelectric coolers, laser modules, full, our full fiber assembly kit, all the connectors, et cetera. So, everything that we do, if you use all of that, the content per chip would be, we estimate it about $15,000 per chip.

Now, it will depend on the customer in their particular application, how much of that content they utilize, whether they utilize a portion of that, all of it, that will really depend on the particular engagement. But that 15,000 is sort of the opportunity that's out there for us. I think we'll see over the next year or two as full-ton link ramps, I think we'll see customers that leverage the vast majority of that, and I think we'll also see customers that leverage a subset of that.

So, I think we'll definitely, we'll see a mix of that. And we're happy to support our customers, whether they want the entire solution or they want a portion of it, we'll work with them on whatever works best for them. But regardless of the amount of content they take, for us, we see this as all greenfield growth, because especially, because most of photon link adoption over time will be driven by scale up. And again, that's all greenfield growth for us, because that's us in the industry converting copper links to optical links over time.

So, we see it as greenfield revenue growth. Got it, that's very helpful. Thank you. The next question comes from Cody Akri with Stonex Financial. Please go ahead. Hey guys, thanks for taking my question. Sherry, maybe for you, from the back to the gross margin discussion, can you maybe help to stratify the contribution part of that? Can you talk about the, in the emposified six-inch ramp yields, increasing utilization rates, maybe even your mixed thoughts? And just, if you can also factor into that, the competitive dynamics on your module and your transceiver piece of, you know, more global Chinese competition, and what's inherently just a more price sensitive market?

Yeah, sure, Cody. I think you cut out a little bit, but I think you were asking for more color on what the drivers are to gross margin expansion over 45%. That's what I think your question is. Yeah, okay. So, if I were to rank order, I think that the largest contributors are going to be our new product ramps, and that full operational leverage of our six-inch in the emposified capacity, and then pricing optimization, followed by cost reduction.

That's kind of how I would rank order it. And the timing of some of those things kicking in, right, will vary, but certainly new product ramps. I mean, those are gross margin and credip, the new products that Jim referred to earlier in his repair remarks. Those are gross margin and credip, and so that will benefit our gross margin. As we continue to shift our supply from external to internal, as Jim talked about a little bit ago, that's going to drive significant opportunity in our gross margin.

And then, pricing optimization, rather, I mean, that is an area where I think we will continue to have benefit there, you know, fully in our data center communication segment, certainly in our industrial too, but definitely in data center communications, there's opportunity for that. We saw that to be a large contributor during the current quarter, as well as in prior quarters, and so that will continue to be a benefit as well, to drive to over 45%. And, you know, cost reductions that will always continue to be something that we focus on, but that's how I would rank order them.

The next question comes from Carl Ackerman with BNP Parabas. Please go ahead. Yes, thank you. Jim, you spoke about how customers are beginning to book out to calendar 2028 that gives you confidence in your growth forecast. At the same time, there is investor concern about the financing and permitting of data centers here in the United States. In light of this, how does the team align its laser production capacity plans with their major customers, and has a team considered customer prepayments for additional laser production capacity?

Thank you. Yeah, thanks, Carl. The answer to the last part of the question is yes, definitely. Maybe I'll start with the end of the question. So we've signed a number of LTA's over the past quarters. The one public LTA that is the one with NVIDIA that we signed back in March, but we've signed a number of other LTA's. The LTA's follow all follow a general pattern. And one part of the LTA is typically some sort of upfront payment from the customer.

It could be either a prepayment or NRE. There's different forms of payment, but there's some sort of upfront payment from the customer. And what we do that for is for two reasons. Number one is it makes sure that the customers have skin in the game. But number two is we use that upfront payment to help fund the CapEx to build the capacity for that customer. We think it's important that if we're going to go build the capacity that the customers, either fund that or help co-fund that.

And so far we've had customers be very willing to do that. And I think that's worked really well for us. And so I would say almost every LTA that we've signed has that general pattern. And so that certainly gives us better confidence and helps offset the risk in terms of our own capital deployment. But I guess on the first part of your question, we certainly work very, very closely with our customers on planning out the demand.

I think one thing to keep in mind with any of our capacity is remember that it's not just being driven by data center demand. There's two things driving optics, in general optics demand, right? Number one is data center growth. But number two is in the case of integrated optics, it's the conversion of the copper links to optical over time. And that is a technology trend that in my view is independent of the market demand. That's a technology trend that will happen and regardless of the data center demand.

Because that's necessitated by the ability to achieve the bandwidth and the link speeds that we need to achieve in the scale up domain or chip to chip is we have to switch to optics over time. And so that's an independent technology trend. And that's certainly part of what's driving the Indian Fosified capacity demand over the long term. The next question comes from Mita Marshall with Morgan Stanley. Please go ahead. Great. Thanks. Maybe just a question on substrate availability.

I think there have been some concern in the market around availability of six inch versus three inch. I know you noted in the prepare remarks that you had gotten the capacity, but it may be if you could just speak about kind of a six inch versus three inch substrate availability and how that's impacting expansion plans. Thanks. Yeah, thanks, Mita. So we have over on six inch in particular, but three inch as well. We do continue to buy three inch wafers.

We do still have three inch production, but all of our expansion is mostly on six inch moving forward. And we have over five different suppliers of substrates. We've signed long term agreements with a number of those suppliers. And when I look at our next step of more than doubling the capacity by the end of calendar 27, we believe we've secured the necessary substrates for that capacity expansion. And then we've certainly, you know, we have plans in place to further expand capacity beyond 27.

And we're certainly working with or already have in place substrate capacity for that as well. So I think the, you know, the summary is we have multiple different suppliers. And we've made sure that we have the substrate capacity for the expansion. The next question comes from Sean O'Lachlan with TD Cowan. Please go ahead. Great. Thanks for squeezing me in. I'll make it quick. Jim, can you just talk about how fungible your capital install, capital install basis across indium-phosphide versus gallium arsenide?

If we, you know, maybe we end up in a world that is more vixxel or multi-core vixxel heavy than it is ultra high power CW. Thanks for getting the question. Thanks. Sure. I would say there's some fungibility, but not, it's not like you can easily switch a line from indium-phosphide to gallium arsenide or vice versa. But I will note that we have a tremendous amount of gallium arsenide capacity. One of the stats that we shared at the PhotonLink launch is that today we have capacity to produce over a billion vixxel arrays annually.

So we have a tremendous amount of capacity that we could deploy. And so to the extent that we saw a broad-based adoption and rapid ramp of vixxel technology, I don't think there's probably anybody else in the industry that's better positioned to source or to supply that demand than coherent is. And so we feel really well positioned on gallium arsenide vixxel technology and ore capacity. And then on indium-phosphide, obviously, we're ramping that very, very quickly. And so I think on both, we're on a good path.

Our last question today comes from Ananda Burra with Loop Capital. Please go ahead. Hey, thank you. I appreciate it. And congrats on the progress here. And I guess, let me, let me ask you a capacity question, supply capacity supply question from the other direction. Yet there's also been a conversation just in the financial community about at an industry level, you know, excess, you know, IMT, EML capacity. At some point in calendar 28, you're also talking, now you're also talking about, you know, sort of contract agreements going sort of well into that timeframe.

So we'd love to get your opinion on sort of how you view the potential for an oversupply situation at an industry level going through 28. Thanks. Yeah, I think through 27 and into 28, I don't see that as a risk given that, given not just the demand that pluggable transceivers is creating, but also the demand that integrated optics is going to create for lasers, as well as there's quite a bit of Indian postified that's also used in some of the DCI applications too.

So when I look across all of that, I don't see an oversupply risk through calendar 28. I also think for us, because most of our Indian postified gets used in our, well, I guess today all of it, today all of our Indian postified gets used in our own products. And we don't even produce enough today for to meet all the demand of our own products. For us, I don't, that's not a primary concern for us. If you know, I think if we were, if there were more supply externally, that may affect us if we were supplying Indian postified lasers externally, but we're not.

And I think our plan is to over time to start to use more Indian postified, more of our internal Indian postified production in our, to change, to increase the mix towards internal over time. So, so I, yeah, I guess the short answer to your question is we don't see any, any big oversupply situation in 28. This concludes our question and answer session. I would like to turn the conference back over for any closing remarks. Thanks. Thanks, operator.

And thanks everybody for joining us on the call today. So we certainly, certainly enter the remainder of the year with a great momentum, exceptional customer demand. And as we were just talking about rapidly expanding capacity, just want to say thanks to, especially to all of our employees, our customers, our partners, and of course, our shareholders for the continued support. And we look forward to updating you again next quarter. Thank you. The conference is now concluded. Thank you for attending today's presentation.

You may now disconnect.

Where this company stands

I read earnings calls because the companies I own are in them, and I publish the transcripts because the call itself beats the headline about the call. Whether Coherent Corp. is one of the ten in the portfolio I run is a question for the Top 10: ten names a month, each with the case for owning it and the risks that would prove it wrong. Its page says what the list is, how to read it and how to get it.
