Good day, thank you for standing by. Welcome to the Coherent Corp FY23 fourth quarter earnings call. At this time, all participants are in a listen-only mode. After the speaker's presentation, there'll be a question-and-answer session. To ask a question during the session, you'll need to press star one one on your telephone. You will then hear an automated message advising your hand is raised. To withdraw your question, please press star one one again. Please be advised today's conference is being recorded. I would now like to hand the conference over to your speaker today, Paul Silverstein. Please go ahead.
Paul Silverstein (VP, Investor Relations)
Thank you, Kevin, and good morning, everyone. Thank you for joining our fourth quarter fiscal 2023 earnings call. Today on the call, we have Chair and CEO, Dr. Chuck Mattera, Chief Financial Officer, Mary Jane Raymond, Chief Strategy Officer and President, Materials Segment, Dr. Giovanni Barbarossa, and Laser Segment President, Dr. Mark Sobey. As a reminder, yesterday, after the market closed, Coherent posted a shareholder letter along with an updated investor presentation. They can both be found in the investor relations section of our website. Before I turn the call over to Chuck for his opening remarks, I want to call everyone's attention to our shareholder letter and accompanying change in format of this morning's call. The shareholder letter contains the traditional financial statements that were previously set forth in our earnings press releases, along with additional color around our operating performance, key trends, and outlook.
Given the additional disclosures in the letter, we plan to devote the bulk of this morning's call to answering questions from the financial community. We've undertaken this change with the goal of providing greater insight and clarity for our quarterly earnings release. We welcome your feedback. I also want to remind everyone on this call that we will refer to forward-looking statements, including all statements the company will make about its future financial and operating performance, growth, strategy, and market outlook, and that actual results may differ materially from those contemplated by these forward-looking statements. Risk factors that could cause actual results and trends to differ materially are set forth in the shareholder letter and in the annual and quarterly reports filed with the SEC. Coherent assumes no obligation to update any forward-looking statements which speak only as of their respective dates.
In addition, during this call, we may discuss both GAAP and non-GAAP financial measures. A reconciliation of GAAP to non-GAAP measures is included in the shareholder letter. Unless otherwise stated, all financial information referenced in this call will be non-GAAP. Our discussion will be limited to those non-GAAP financial measures that are reconciled in the shareholder letter. Today's conference call will be available for webcast replay in the investor relations section of our website for one year. With that, it is my pleasure to turn the call over to Chuck. Chuck, please go ahead.

Thank you, Paul. I hope those of you listening in have had the opportunity to read our new shareholder letter. In the fourth quarter, the Coherent team did a good job executing in the midst of a challenging macroeconomic environment. Our revenue of $1.205 billion was above the high end of our guidance, and non-GAAP EPS of $0.41 was toward the high end of our guidance. Operating cash flow was $182 million, which marked sequential and year-over-year improvement. We invested $93 million in capital equipment, and we retired $121 million of debt. When I look back on fiscal year 2023, Coherent, Inc. contributed to our resilient business model. In addition, our track record following our acquisition of Finisar once again speaks to our ability to successfully effect strategic acquisitions and thereby create shareholder value.
Two major highlights in fiscal year 2023 were related to our acquisition of Finisar. We demonstrated our unique scale while generating nearly 20% of our FY23 revenues from just two customers, one in communications and one in electronics. These are good examples of the strength of our vertically integrated platforms, which enable breakthrough solutions and our differentiated ability to scale to meet sudden increases in market demand, like those that we are now seeing in AI. While we experienced a surge in orders in Q4 in communications for AI, the macroeconomic uncertainty that affected some of the industrial and instrumentation businesses, a slower than forecasted recovery in China, and a post-COVID deceleration in the communications markets drove the conservative fourth quarter order patterns for some of our customers' legacy products.
Recently, some of those customers have taken actions, including reducing orders of le-legacy products in the face of lower demand and reducing their inventory levels while slowing their planned investments in CapEx. This setup presents the ongoing challenge of managing through a retooling in FY24, and so we got busy during Q4 to align our costs with market reality. We view this temporary slowdown in demand as an opportunity to strengthen our foundations. We remain bullish about the future because many of our largest customers are also resetting their strategies and accelerating their investments in new products that depend on our innovations and our ability to manufacture at scale. The largest opportunity in FY24 that we are addressing is for 800G datacom transceivers for planned artificial intelligence and machine learning build-outs.
That demand should help offset the anticipated declines in demand from our traditional data center and hyperscale customers in data communications in fiscal 2024. In addition, we continue our review of strategic alternatives for our silicon carbide business, another one of our major growth opportunities. Thanks to our strategy of diversification, we believe that we are well-positioned to benefit from any improvement in the macroeconomic environment, though our outlook assumes that we will not see meaningful signs of recovery before the end of fiscal 2024. In short, we are prepared for a reset year, and we consider these challenges as a temporary interruption of otherwise powerful secular trends. Our guidance for the first quarter of fiscal 2024 is revenue of approximately $1 billion-$1.1 billion, and non-GAAP EPS of approximately $0.05-$0.20 on 153 million shares.
Regarding full year FY24 guidance, revenue of approximately $4.5 billion-$4.7 billion, and non-GAAP EPS of approximately $1.00-$1.50 on 153 million shares. With that, I'll turn the call back over to Paul. Kevin, if you could open it up for questions. Thank you.
Operator (participant)
Thank you. Ladies and gentlemen, if you have a question or a comment at this time, please press star one one on your telephone. If your question has been answered, or you wish to move yourself from the queue, please press star one one again. We'll pause for a moment while we compile our Q&A roster. Our first question comes from Samik Chatterjee with JP Morgan. Your line is open.
Samik Chatterjee (Analyst)
Hi, good morning. Thanks for taking my questions, and thanks for all the details in the shareholder letter. Very useful to get all those details. Maybe if I can start with just a sort of clarification question on the AI/ML guide, and particularly sort of the inclusion in the guidance or deciding not to put it in the guide. Sort of maybe if you can sort of walk us through, are we sort of to interpret that you're not putting any of those AI/ML sort of orders in the guide for fiscal 24? Or is there sort of some amount of it in the guide relative to what you have more sub-capacity visibility around? You do mention sort of capacity ramp as one of the hurdles, I think, in the shareholder letter in relation to fiscal 24.
Maybe if you can walk us through, what are you seeing in terms of capacity challenges, what do you need to sort of see in terms of milestones to include that in the guide going forward? I have a quick follow-up. Thank you.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay. Thank you, Samik. I'll take that. Maybe three points are helpful. The first one is that the, the Q4 bookings that we had, had a, a surge that we reported, that surge was all about AI. That's number one. Number two, we have revenue for 800G transceivers contemplated inside our guidance in the $4.5-$4.7. There's meaningful revenue for a delivery of 800G transceivers. Those have already started. In the first half of the year, we will see a ramp from Q1-Q2, the substantial amount of revenue we will deliver, it will be in the second half of the year. What's, what's in front of that is managing our scale and especially managing our supply chain.
We, we see the opportunity for over and above what we have in our plan, but that, that opportunity will require quite a few more synchronizations, including in the supply chain. As we work our way through in the next few months, through the first and second quarter, we'll have our eyes set as we work to compete for the greater opportunity that may come inside this fiscal year.
Samik Chatterjee (Analyst)
Okay, good. Good. Thank you, Chuck. Then you did outline in the presentation in the shareholder letter, like, three separate opportunities in AI/ML relative to EMLs, your DFB laser, as well as VCSELs. Any sort of thoughts in terms of broader terms, where you see the most of likelihood of success within those three buckets? Where most of these orders are coming in right now, that you're seeing, in which bucket is that coming in? Thank you.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay. Well, I'll, I'll start out, and then I'll ask Giovanni to finish it off, Samik. As you know, we're a vertically integrated supplier, and in addition to selling both VCSEL-based and EML-based transceivers for this application, we're also a supplier to the merchant market. Having said that, our ability to scale both at, at high performance and high volume and high quality to be able to meet this ramp, is partly the, the basis on which we're going to continue to win both new orders and to be able to ship. Giovanni, please, elaborate. Samik, I, I would say that, roughly right, would be like 1/3 short reach, short wavelength, 2/3 long reach, long wavelength, and, you know, which obviously we can, we can support both with our internal devices.
We see that kind of ratio being different in terms of volumes because, you know, price is different, so the volume will be probably 50/50. That, that kind of ratio will probably be the same for the next five years. I'm specifically talking about AI here, right? The 800G and maybe even the, in the future, the 1.6T, et cetera. That kind of ratio will, will remain in the next few years, too.
Samik Chatterjee (Analyst)
Got it. Got it. Thank you. Thanks for taking my questions.
Vincent D. Mattera, Jr. (Chair and CEO)
Thank you, Samik.

One moment before our next question.
Our next question, Simon Leopold with Raymond James. Your line is open.
Simon Leopold (Analyst)
Great. I appreciate you taking the question and providing all the detail last night. Gave us a little bit of time to try to digest this. So maybe a couple of aspects around the exclusion of the AI-related datacom from the guidance. Could you help us understand the rationale for backing the AI-related business, which you describe as worth $several hundred million out of the guidance? Help us understand as well, if we wanted to include this in our own estimates, what do you think the impact would be on the EPS? Just as a very, very quick follow-up to this question, what assumption do you have in terms of your market share of 800G and above transceivers? Thank you.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay, Simon. Simon, let me, let me clarify. Let me repeat what I said in, in, in response to Samik's question. Our guidance, our revenue guidance for the full year, and for the first quarter, but especially for the full year, contemplates a meaningful amount of revenue for shipping 800G transceivers. I wanna repeat that. Our plan contemplates a, a, a substantial amount of shipments. I believe that there may be additional upside, and that additional upside might be as much as $200 million. For us to have the confidence to add it into our plan, we need to, we need to manage quite a few aspects of our ramp, and we're going to go for it.
But I cannot be sure that we'll, we'll be successful in having everything come together in time to be able to have the confidence to add that $200 million or up to $200 million, but we're focused on it. If we have anything more to say 90 days from now, we will. With regard to your, your second question, our belief is that we're in a market leadership position. It's a competitive market. There, there are strengths that we bring, and we're going to continue to compete on the basis of the strengths that we have in this generation. Those strengths I outlined were evident in FY23, with a rather substantial ramp in datacom transceivers, year-over-year, from 2021-2022-2023.
We have the ability to scale, and we have the laser components for the, the generations that exist today and the 1.6T, which are coming. On that basis, on that basis, I think it's, it's, it's the first inning. It's very difficult to, to be assessing what the score will be in the fifth inning and the sixth inning of the game. Everybody's just getting started, we're well-positioned to be able to move even further past our own aspirations for our leadership position in this market.
Simon Leopold (Analyst)
That's very helpful. Just to, to sort of paraphrase it, to make sure it's crystal clear, that the exclusion is, is because of risk of ramping the production, capacity, shipping. It is not because you believe this is sort of a one-time, flash in the pan kind of project. This is the beginning of a cycle, correct?
Vincent D. Mattera, Jr. (Chair and CEO)
Right. This is the first inning of the game. It's the beginning of... I'm not even sure it's a cycle. It's the beginning of a revolution, and there's a lot more to come, we believe. By the way, if 90 days from now, I can update you on the, the, the possibility of additional revenue that we can add to the guidance, if we're able to operationalize it, there may be more to come, because this is just getting started, and we think that in 2024, rolling into 2025, is gonna continue to drive our growth.
Simon Leopold (Analyst)
Thanks for taking the question, Chuck.
Vincent D. Mattera, Jr. (Chair and CEO)
You're welcome, Simon.
Operator (participant)
One moment before our next question. Our next question comes from Meta Marshall with Morgan Stanley. Your line is open.
Meta Marshall (Analyst)
Great, thanks. Maybe just outside of the transceiver business for now. You know, you had noted that visibility increased during the quarter. I just wanted to get a sense of, you know, whether that visibility increased anywhere outside of datacom transceivers. You know, as you look at recovery of the business, either, you know, late in the second half of the fiscal year or into fiscal 2025, just what segments are most likely to kind of recover first outside of datacom? Thanks.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay. Meta, thank you for your question. Well, the telecom business itself, given our position of, of our portfolio, the strength that we have with the telecom customers, I'm expecting that the second half of the year to be better than the first half of the year, and that we'll expect to I, I do expect to see some signs of recovery before the end of this calendar year. Signs of recovery will be follow through on new orders, and those new orders will be consistent and commensurate with both the launch of some new products, including our, our pluggable DCO modules, and the ramp of those products from a base that we, we believe we can grow our share meaningfully beginning the second half of next year. Telecom would be, be one.
I do think the industrial market is broad-based, we're diversified. I don't wanna say that we're at, at the bottom, but I do believe that any meaningful increase in macroeconomic activity, we will begin to see it both in laser utilization, in our service business, and the further adoption of laser technology, including for EV battery welding, as just one example. Our silicon carbide substrate business is, is growing. Is growing super nicely, I would say, and I'm expecting that to continue into 2024. Maybe I'd, I'd stop, and Meta, take a follow-up, if you like.
Meta Marshall (Analyst)
Yeah, no, just as a follow-up, I mean, just to come back to datacom transceivers, you know, when you talk about this kind of additional $200 million, is the majority of the gating item your capacity, or are there other gating items to kind of recognition of that?
Vincent D. Mattera, Jr. (Chair and CEO)
Meta, every manufacturing line has a first constraint, and when it's broken, there's one right behind it, the second constraint. Our job and our expertise is being able to figure out how to manage multiple constraints at one time. Managing the supply line, we have critical components that we're dependent on, that supply line, for the last SIX months or so, has been in a wind down mode, with the tide going out. The rather sudden adoption in the beginning of this the game, in this first inning, caught many, many in the industry by surprise. Therefore, we have to manage through certain aspects of the supply line.
It's, it's going, but if it were going faster, we'd be able to take on more, 'cause we have the capacity to do more, and we're aiming to do more. I believe that customers want us to do more. In the next couple of months, the urgent approach to managing our entire manufacturing capacity will continue, and we'll give an update in 90 days.
Meta Marshall (Analyst)
Great. Thank you.
Operator (participant)
One moment for our next question. Our next question comes from Vivek Arya with Bank of America. Your line is open.
Vivek Arya (Analyst)
Thanks. One more, on, on datacom. For fiscal 2023, what was your total datacom transceiver sales, and how much was that in AI/ML? I'm curious, how are you drawing that line? Is it anything above 200G? That's my first question.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay, Vivek, good morning. Thanks for your question. Let me, let me give it to you in broad strokes, 'cause I think that's that, that'll do it for you. Our datacom transceiver sales in FY23 were approximately 20% of our consolidated revenues. As it relates to AI, whereas there may be some applications and sockets that are at data rates that are less than 800, for us, when we talk about it, we're really talking about 800, and you'll hear us talk about our roadmap for 1.6. In FY23, it was not a material amount. We began shipping in the third quarter, and it's going to step up rather substantially in FY24.
Vivek Arya (Analyst)
Okay. Thank you, Chuck. For my follow-up, I was hoping if you or Mary Jane could provide the bridge between the sales guidance and then the earnings, you know, guidance. What are you assuming for gross margins in fiscal FY24, and the exit OpEx rate in fiscal FY24?
Vincent D. Mattera, Jr. (Chair and CEO)
Okay, thank you, Vivek. Mary Jane?
Mary Jane Raymond (CFO)
I think with respect to the whole year, we're widening our gross margin range to 37%-42%. At lower revenues, similar to what we have in the guidance, you know, given the importance of volume, the, the margins may not be at 40 every quarter. That's the first thing. The second thing is, similarly, at the same level of revenue that we're talking about for the full year guidance, the OpEx tends to be a little bit higher percentage of sales, not because the dollar value of the OpEx is going up, but because the revenue is lower. It's probably in the neighborhood of about 22% or 23%, which is the high end of our range of 20%-23%. That's the, the way we're looking at it.
I do think that, as the year goes on, we will probably see the margins improve as the volume picks up, especially if some of the outlook that we have that we think covers somewhere between the next 2 to 4 quarters, starts to recover in the back half of the year.
Vivek Arya (Analyst)
Mary Jane, how do we reconcile, I mean, you're guiding sales down, I think, what? 11% at the midpoint, and earnings down almost 58% at, at the midpoint. What declines a lot more? Because gross margins, from what you're suggesting, sort of seem to be about where they are in fiscal '23, unless I'm getting that wrong. What are those missing pieces that are driving, you know, Is it share count? Like, what is making earnings decline so much faster?
Mary Jane Raymond (CFO)
Comparing to 2023, I mean, the revenue alone, comparing just to the, to the $4.7 billion, sorry. The revenue alone is $0.91. The revenue declining is a significant impact on the earnings. From there, you know, the taxes make a difference, the dividends change somewhat, even though we have the share count converting on the Series A, the in-kind dividends also start to go up because they're capitalized. Those are probably the major things, but the revenue being below 2023 is the primary driver.
Operator (participant)
Okay, thanks. I'll follow up separately.
One moment before our next question. Our next question comes from Tom O'Malley with Barclays. Your line is open.
Tom O'Malley (Analyst)
Hey, thanks for taking my question. I just wanted to see what silicon carbide was as a percentage of total revenue in the June quarter. In the prepared remarks, you talked about the continued supply constraints just from not being able to scale, but you also said it grew nicely. Could you just give it for the June quarter?
Vincent D. Mattera, Jr. (Chair and CEO)
Yeah, good morning, Tom. Just give us a second. Yeah.
Mary Jane Raymond (CFO)
The whole of the wide bandgap product line was about 6% of revenue.
Tom O'Malley (Analyst)
Okay, thank you. I just wanted to ask a just a technical question. Maybe this is in Giovanni's camp. In terms of AI connections that you're seeing today, I thought it was interesting in your, in your, in your slide deck, you showed that the biggest growing opportunity between 2023 and 2028 is the silicon photonics portion, where you have it going from, like, $800 million to $4.6 billion. Where are you guys playing in silicon photonics, and why is that growing so fast in that period of time? Thank you.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Well, there are solutions that, you know, from a power consumption and, you know, generally speaking, performance standpoint, are better suited for silicon photonics. You still need a, you know, still need a laser for those solutions. We see, I would say there is a split. Silicon photonics is not, in the slide, it's not identified. You know, it's not split between short reach and long reach, short wavelength, let's say, or what we call a short reach, long reach. I would say that split is still a one-third short reach, two-third long reach, and both of them are related to the AI ramp that we talked about. That's what we are seeing. The growth...
And by of course, there is not that's not all, all of, all of it. That's growing fast, but there's also there's a VCSEL part, which is also growing very fast, and that's unrelated to the silicon photonics part. Just, with respect to silicon photonics, that's a split between, still all AI, but it's a split of, let's say, one third, two-third, short reach, long reach.
Tom O'Malley (Analyst)
Thank you.
Operator (participant)
One moment for our next question. Our next question comes from Jed Dorsheimer with William Blair. Your line is open.
Jed Dorsheimer (Group Head of Energy and Power Technologies)
Hi, thanks, and thanks for taking my question. Just as a follow-up to the previous on silicon carbide, am I looking at this correctly, that if, if I look at the wide bandgap and I strip out indium phosphide, the silicon carbide is roughly 70% of that business, and, you know? Or is there anything else that I need to be aware of in that business?
Vincent D. Mattera, Jr. (Chair and CEO)
Jed, can you repeat your question?
Jed Dorsheimer (Group Head of Energy and Power Technologies)
Yeah.
Vincent D. Mattera, Jr. (Chair and CEO)
Set of financials?
Jed Dorsheimer (Group Head of Energy and Power Technologies)
What I'm trying to get at is the growth in silicon carbide. Previously, you've said that that was 3% of sales, and now wide bandgap is a total of 6%. Within wide bandgap, I think the other major component is indium phosphide, but that seems to be relatively small, of about 20%-30%, so the vast majority is silicon carbide. Is there anything else that would need to be removed to get back to that silicon carbide? Because what I'm trying to understand is the growth year-over-year of that business.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay, Jed. Jed, in our wide bandgap electronics platform, the majority of the sales are for silicon carbide substrates. That's, there, there are no indium phosphide or gallium arsenide. There's nothing of any other compound semiconductors, but we do have our ion implantation services business, which includes providing ion implant services for silicon carbide to, to, to customers who are operating fabs. It is silicon carbide based, and that's the focus of our wide bandgap electronics platform. It is growing. It is outpacing the growth of the company.
Mary Jane Raymond (CFO)
It's been 4%-5% for the last several quarters, Jed.
Jed Dorsheimer (Group Head of Energy and Power Technologies)
Got it. Okay. Well, then I guess maybe just, you mentioned that in the shareholder letter, that 40% of the CapEx was directed to this business unit. Then last quarter, I think you updated saying that you were looking at a strategic review of this business unit. It's a lot of CapEx for, you know, something that's relatively small, albeit growing. Just how should we think of that percentage in the 2024 guide? Do you expect a linear growth, or, or are you expecting with this capital intensity, in terms of expansion, that that would be nonlinear?
Vincent D. Mattera, Jr. (Chair and CEO)
No, I'm expecting that in FY24, and planning, that above 40%-50% of our capital will be invested in silicon carbide to fuel the growth.
Jed Dorsheimer (Group Head of Energy and Power Technologies)
Sure. What I was getting at, though, Chuck, is, is so in a business that you're, that you're looking at a strategic review, which could take different forms, that's a lot of CapEx that you're putting into that business. Are you expecting nonlinear growth in that segment? So in other words, if you're at 6% right now, you know, in that forecast, is that expected to double? That's what I'm to justify the CapEx in that business unit.
Vincent D. Mattera, Jr. (Chair and CEO)
Mary Jane, would you like to?
Mary Jane Raymond (CFO)
Well, certainly, I think as we have seen and talked about probably in prior quarters, you know, as the mainline vehicles from kind of mainline car suppliers start to move to electric, we absolutely expect that this market will have an inflection point upwards. I think we're only seeing just the beginning of that. The growth was very strong in the fourth quarter. It was strong in the third quarter. I think we do expect that to continue. Obviously, customers, it's fortunately, this business is somewhat more rational than other parts of our business. It's important for the capacity to be there for people also to commit to being able to change over, you know, and half of their entire car lines, if not more than that.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay. As is in Giovanni, segment, would you like to?
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Yeah. Jed, just, I'll, I'll give a number of FY23, FY24, we expect growth of at least 40%, four-zero. Okay?
Jed Dorsheimer (Group Head of Energy and Power Technologies)
Great. Thanks. Thanks, guys. I'll jump back in queue. I appreciate the color.
Vincent D. Mattera, Jr. (Chair and CEO)
Thank you, Jed.

One moment for our next question. Our next question comes from Christopher Rolland with Susquehanna. Your line is open. Christopher, your line is open, you can ask your question.
Christopher Rolland (Managing Director and Senior Equity Analyst)
Hi, sorry, on mute. Yes, I was wondering if you guys might be able to talk about any kind of nontraditional engagements. Have you guys had any engagements for optical or lasers into things like AI systems or servers or cards? Perhaps if you could talk a little bit more broadly about the economics for AI, just in your transceiver business, how margins compare to corporate, what the OpEx needs are to support that business, et cetera. Thanks.
Vincent D. Mattera, Jr. (Chair and CEO)
Yeah. Chris, will you repeat the first part of your question, the non-financial part?
Christopher Rolland (Managing Director and Senior Equity Analyst)
Yes. Your competitor, for example, is starting to talk about custom AI designs that are going into systems, not just transceivers. I was wondering if, if, if any hyperscalers have, have engaged you, any comp AI specific companies have engaged you, in custom designs?
Vincent D. Mattera, Jr. (Chair and CEO)
Giovanni, would you-
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Yeah, sure. Well, let me, let me start with the, our strength in the device technology. We, we kindly ship and sell, more devices than we actually use internally. We, you know, most of our competitors are actually our customers, too, as you probably know. Because of the broad-based, laser and, you know, receivers, technology platforms that we have, we're both in short wavelength, short reach and long wavelength, long, long reach. We are, engaged on, some, let's say, non-standard designs with some, end customers. Even those customizations, at the end of the day, in terms of, you know, guaranteeing interoperability, they will have to be standardized at some point.
I, I don't believe there is any, you know, any difference, in terms of the process of standardization that we've seen in the past, you know, 20 years in the datacom world. Of course, as the people trying to improve performance, cost of ownership, et cetera, you know, there are, there are, there are ways to customize a solution internally. I, I want to remind you that at the end of the day, all of these X hundred Gs are all 100Gs optical lanes. It all comes down to 100G anyway. Some of them are parallel, some of them are, you know, different type of approaches, multiplex and so forth.
At the end of the day, it's all 100G in the optical lane level, even if there may be, you know, 200G electrical lanes coming soon, and in, in the future, of course, 200G optical lanes coming soon. Today, that's where we are. There is some level of customization, but I don't, I don't think it changes the, the, again, our ability to compete is still substantially better than, I would say, most of our competitors, because we, as you know, we are the most vertically integrated out there, which doesn't only improves our ability to, as you know, we were saying earlier, to ramp and support the demand that, that we see, but also the ability to differentiate at the transceiver internal design level.
We are engaged from that perspective in some of these super customer, they call it customized solution for some of the AI players.
Vincent D. Mattera, Jr. (Chair and CEO)
Jane, would you
Mary Jane Raymond (CFO)
With respect to the margins. Generally speaking, you'll remember that the communications, entire end market, the margins tend to be below the corporate average. Having said that, the higher data rate and typically more technologically complex products that deliver a greater value, tend to have margins that are above the average within communications, to a pretty decent extent.
Christopher Rolland (Managing Director and Senior Equity Analyst)
Great. Thank you very much.
Vincent D. Mattera, Jr. (Chair and CEO)
Thanks.
Christopher Rolland (Managing Director and Senior Equity Analyst)
For my second question here, I know it's hard to figure this out, and inventory at your customers, and I know it's going to take a few more quarters here to work through, but is there any way to kind of quantify, what this inventory burn is, what you think normalization would have been, at your customers? you know, how, how much more would you have shipped if you were shipping in line with demand? any thoughts on that? Then any thoughts on perhaps the linearity of how this inventory dynamic plays out? Thanks.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay, Chris,I won't, I won't be able to speculate on what it could have been. It's, it's be too complex a function and have great, great uncertainty, I think. 90 days ago, I said I thought that, that the moderation would persist at least until the end of this calendar year, and maybe longer. It's still, still not possible to, to call it any better than, than the remarks I made earlier. As it relates to telecom, as a kind of a primary market where we are affected by it, I am hopeful for sure, and, and, and looking and engaged in discussions with customers.
I believe that we, we won't see a turn-up before this second half, and, and I believe that we will begin to see some signs of it by then.
Christopher Rolland (Managing Director and Senior Equity Analyst)
Great. Thank you, Chuck.
Vincent D. Mattera, Jr. (Chair and CEO)
Thank you, Chris.

One moment for our next question. Our next question comes from Ananda Baruah with Loop Capital. Your line is open.
Ananda Baruah (Managing Director, Senior Equity Analyst)
Hey, good morning, guys, and thanks for taking taking the questions. I guess two, two, if I could. In the in the shareholder letter, you guys also talk about sort of AI exposures being more than just AI transceivers, and I think there's mention made of AI active and passive components, high-speed lasers, and was wondering if you could could drill down on that. I think you gave some context at OFC on this as well, but would love to get context on that and any any updated way you're thinking about that. Then I have a quick follow-up. Thanks.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay, Ananda, Giovanni, maybe just talk about VCSELs, EMLs, and optics.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Yeah. Ananda, yeah, I guess you were wondering if the, I mean, obviously, the, the largest share of the revenue upside that we see in, in the year due to this surge in demand, which was, by the way, was a surge because it was unexpected in terms of size and timing, but not necessarily unexpected from a market trend. 'Cause we know, we know it, it was gonna come at some point, but it caught us a little bit by surprise, and fortunately, we had, you know, we do have the 800G platform ready, so it's more a question of, you know, logistics and supply chain and ramping up. That's a one, one, one detail.
In terms of the, you know, the split, let's say, let's call it between modules and devices, let's say transceivers and, and lasers, photodiodes, in some cases even ICs, obviously, the transceiver is 90% of the total. That's kind of the split that we see in the, let's say, in the next 12 months, in the, in the fiscal year, in the fiscal FY24. That's kind of roughly right, the ratio, revenue-wise.
Ananda Baruah (Managing Director, Senior Equity Analyst)
That's helpful, Giovanni. I appreciate that. I guess as, as the follow-up, like, thanks a lot for the detail on the AI transceiver TAM in the, in the slide deck and the go-forward view. Any, any opinion on what-- like, where you ultimately sit share-wise, in the various buckets, the way you've laid them out? I mean, just, just sort of bigger picture. Do you think you're in a position to gain share going forward as well? Any context around that would be helpful. Thanks.
Vincent D. Mattera, Jr. (Chair and CEO)
Ananda, we are the largest transceiver maker in the marketplace, and as it relates to this 800G opportunity and more broadly, AI, including the generations to come, our goal is to be the market leader. It's early as a starting point, but even though it's early, we've gotten busy. I believe that in 2024, what we have baked into our plan is already a super exciting ramp. I believe that there will be possible upside of several hundreds of millions, even in 2024, in the back half of 2024. I believe that our ability to address the market, to serve the market, to scale on the market, is gonna be critical for us to be able to win. Our goal is to be the market leader.
Dave Kang (Research Analyst)
Chuck, is there anything about how you're sort of going to market with the sort of technology portfolio that you have, that you think could increase your advantage in the market, ignoring the 1.6T, et cetera, relative to where you are today already as the leader?
Vincent D. Mattera, Jr. (Chair and CEO)
Yes, absolutely. As let me repeat. Our laser-based technology, both short wavelength and long wavelength, and the demands on that laser technology, including for 800, but especially for 1.6, will separate us even further from the other players in the marketplace, because we are the only vertically integrated company that has a roadmap to support well beyond 800G. I, I believe that those are among the very strong value propositions that we present to a customer.
Dave Kang (Research Analyst)
Very helpful. Thanks a lot, Chuck.
Vincent D. Mattera, Jr. (Chair and CEO)
Thank you.

One moment before our next question. Our next question comes from Ruben Roy with Stifel. Your line is open.
Ruben Roy (Managing Director and Equity Research Analyst)
Thank you. Chuck, if I can ask you to put a little bit of a finer point on the AI/ML transceiver momentum you're seeing, how would you characterize the relative strength today, at least, in sort of optics going into InfiniBand AI training clusters versus Ethernet? Really what I'm trying to get to is, if you can give us a sense of timing and qualification cycles for Ethernet deployments at 800G, and then eventually 1.6T, would be helpful.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay. Ruben, I, I'll ask Giovanni to, to address both.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Yeah. There is we are absolutely agnostic to the, ultimately, the switch architecture of the customers, right? If you're talking about, you know, maybe the market, where the demand is, you know, maybe, maybe there is a higher demand from InfiniBand than, than Ethernet and the rest, right? But, but from just from a hardware standpoint, it makes absolutely no difference to us.
Ruben Roy (Managing Director and Equity Research Analyst)
Okay, Giovanni. Are you qualified then for, you know, some of the, I, I think some of the cloud service providers are talking about moving to new Ethernet switches, 51.2 terabit, et cetera? Are you qualified, you know, as those, you know, switches move out at some point in 2024?
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Yeah, absolutely.
Ruben Roy (Managing Director and Equity Research Analyst)
Okay. Okay, I guess one last question for Chuck or Giovanni. You mentioned, you know, 20% of consolidated revenue in FY23, related to, you know, what you would consider AI/ML. That leaves a pretty big portion of sort of how I would consider legacy transceivers, 200G, maybe and lower. How do you think, you know, that plays out? Do you think, you know, the AI/ML stuff is going to ramp, you know, faster than legacy falls off or, you know, legacy sort of hangs in there? How are you considering that?
Vincent D. Mattera, Jr. (Chair and CEO)
Okay. Ruben, let me clarify. My earlier comment was that about 20% of our consolidated FY23 sales were in datacom transceivers.
Ruben Roy (Managing Director and Equity Research Analyst)
Okay, I got it wrong.
Vincent D. Mattera, Jr. (Chair and CEO)
Let me ask you if you have any question about that.
Ruben Roy (Managing Director and Equity Research Analyst)
No, I.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay.
Ruben Roy (Managing Director and Equity Research Analyst)
I messed that up then on my end. Thank you, Chuck.
Vincent D. Mattera, Jr. (Chair and CEO)
Oh, it's all right. Well, I'm glad we're talking. As we indicated in the shareholder letter, we had a 10% customer in the communications market that was in the data communications market. The demand for those legacy products in my prepared remarks, I alluded to a declining demand for certain legacy products from our customers. That demand in FY24 is going to roll off. That is our plan. As it rolls off, even faster than it rolls off, I'm expecting that inside the fiscal year 2024, that we are able to replace it with 800G AI transceivers at a minimum. We're aiming to do more than that. Is that clear?
Ruben Roy (Managing Director and Equity Research Analyst)
Absolutely. That's what... Yeah, it's contemplated. I appreciate the detail, Chuck. Thank you.
Vincent D. Mattera, Jr. (Chair and CEO)
You're, you're welcome, Ruben.

One moment for our next question. Our next question comes from Dave Kang with B. Riley. Your line is open.
Dave Kang (Research Analyst)
Thank you. Good morning. My first question is regarding your transceiver revenues. What was the split between a different speed, like 100 gig, 400 gig, last year? Now with 800 gig ramping, what do you think that mix will be this fiscal year? What's the margin differential between 100 gig versus 400 and 800 gig? Thank you.
Vincent D. Mattera, Jr. (Chair and CEO)
Giovanni, do you want to-
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
I would say that the 200, 200 gig and above was about maybe, I would say, 30% of the total, and the rest was 200 gig and below. However, let me tell you the split between... the, sorry, the other way around. Sorry, I inverted the number.
James Ricchiuti (Senior Analyst)
Just repeat it. Just repeat.
Mike Genovese (Senior Research Analyst)
So Giovanni, you, so 200 gig and above was 70%? Just wanted to make clear.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Yes, exactly. Yes.
Mike Genovese (Senior Research Analyst)
Okay. Okay.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Now, in terms of the, the major change in our revenue distribution has been, if you recall in the past, we said that, you know, one-third was hyperscalers, one-third, let's say, top 20 cloud, and then, you know, and then one-third rest, let's say, enterprise and the rest. As a result of the shift to AI and the result of some inventory in the, in, you know, what we did over, you know, the FY23, that ratio has actually changed now to two-third is around AI, at least for FY24, and it's most of it will be 800G, 200G and above, of course, including 800G. The rest is, let's say, it's more cloud players and, and enterprise.
That ratio, 1/3, 1/3, 1/3, is like 2/3, and then the other 1/3 split between the remaining cloud providers and the enterprise. Hyperscalers will be a much larger share of the total than in FY23.
Mike Genovese (Senior Research Analyst)
How does, how does that, that, that transition, that, the shift, impact the, the margins?
Mary Jane Raymond (CFO)
As, as I noted earlier, the, the margins on the higher data rate, more technologically complex products tend to be higher than the average in a given group. In the case of transceivers, these, these greater than 200G and certainly 800G would be above the average. Having said that, for those parts that are, say, 100G and below, at some point would become very, very, very good at making those so the, the lower margin products or average margin products tend to hold, actually, because as time goes on, also, we're almost the only one that makes them. Generally speaking, that's how you should think about the margin structure there.
Mike Genovese (Senior Research Analyst)
Got it. Mary Jane, just my last question is on your backlog, $2.7 billion. I was wondering if you can provide the split between your three divisions, and also if you can provide. I know you provided operating margins for three divisions. I'm wondering if we can get gross margins for those three.
Mary Jane Raymond (CFO)
With respect to the backlog, for the material segment, of the $2.7 billion, it's about $650 million. Of the networking segment, it's about $1.2 billion, and the balance would be in lasers. With respect to the gross margin of the segments, we don't typically give that, as you know. I think that you can imagine that it basically goes in somewhat parallel to the operating margin, remembering that grown materials and laser diodes have the highest margins in the company, along with typically our industrial products. The laser systems are typically slightly above the corporate average, and the telecom-- the communications margins tend to be below the corporate average.
Mike Genovese (Senior Research Analyst)
Got it. Thank you.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Thank you, Dave.

One moment before our next question. Our next question comes from James Ricchiuti with Needham & Company. Your line is open.
James Ricchiuti (Senior Analyst)
Morning. Mary Jane, I wonder if you could, you'd be willing to share any targets for debt reduction in fiscal 2024. You know, maybe at, say, at the midpoint of your full year guidance, how should we be thinking about that? I have a follow-up.
Mary Jane Raymond (CFO)
Well, we haven't previously talked about targets for debt reduction. Obviously, we would have strived to be north of 200 on that. Paying down the debt remains a very, very high priority, a very, very high priority. To the point that while the CapEx is the first call on the capital structure, we have been very, very aggressive about managing that CapEx, because to some extent, the CapEx naturally moderates in periods of lower revenue.
James Ricchiuti (Senior Analyst)
Looking at the comments you made in the shareholder letter on the display side of the business, I'm wondering if you are expecting any kind of seasonal pickup in utilization that's going to drive that part of the business in the first half? You know, just in light of what we're hearing from, you know, one of the suppliers of OLED materials into the handset market. On the system side, you alluded to pick up in orders out of China. Is that deliveries for fiscal 2024 or the bulk of those in fiscal 2025? Thanks.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Great. Great questions, Jim. Thanks for your question. Mark, will you address both?
Mark Sobey (President, Lasers Segment)
Thanks, Chuck. Hi, Jim. Yes, we definitely expect service utilization pickup in the first half of our fiscal year, so over the next six months. As you know, we get a batch of new smartphone releases from various manufacturers, typically in the September-October period. Yeah, we've certainly got visibility into having expectations that, that would drive our service revenue. The bookings that we mentioned on our new OLED capital equipment, the shipments are in FY24. Those, those shipments are within the fiscal year.
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Okay. Mark, how does that compare with past investment cycles you've seen in this part of the business?
Speaker 20
That's a great question. I think it's pretty similar. I mean, you know, we've, we've, you know, we'd love this business to be more linear. It's, it's not. It tends to, it tends to be associated with fab build-outs, as you know, and we've got a limited, you know, number of customers, six to eight major, major customers, split between today. It's pretty much split between China and Korea. I think it's, I think it's pretty similar, tends to go in phases. Each phase, you know, is typically three to four systems, so you can imagine that the orders that we recently collected were in that sort of range. We would expect additional phases to be built out, as well as, we've mentioned many times in prior calls, an expectation of generation eight fab build-outs, especially in China.
Yeah, we see this as reasonably typical.

Our next question comes from Tim Savageaux with Northland Capital Markets. Your line is open.
Tim Savageaux (Managing Director and Senior Research Analyst)
Hi, good morning. You know, a couple of questions here, and maybe they're related, which is, specifically, I wanted to focus on trends in the telecom business from a demand standpoint, and you probably have some inventory issues there as well. As you look through to end demand, what can you tell us about what's happening there? Kind of related to that, if we look at the September quarter guide going down, you know, something on the order of $150 million, if you look across your segments, you know, what are the main kind of drivers there in terms of puts and takes from a sequential standpoint? Thanks.
Vincent D. Mattera, Jr. (Chair and CEO)
Okay, thank you, Tim. We had a very strong shipments in communications in the 4th quarter. I think that, that'll be down in the 1st quarter. I think that's the number one driver in the change from Q4-Q1. That, that, that accounts for maybe more than half or 2/3 of the variation, and the rest of it's spread across the other markets, or across the other segments, and markets. What was the second part of your question?
Tim Savageaux (Managing Director and Senior Research Analyst)
Well, I guess, I get you. No, I'm, I'm with you. To the point, to the extent you're talking about comms being half to two-thirds of the decline, I guess I was trying to get a sense of telecom versus datacom there.
Vincent D. Mattera, Jr. (Chair and CEO)
It's a, it's a combination, and the moderation that we saw in the March quarter in the telecom market, that persisted in Q4, and it will leak into, at least leak into Q1 as well. It's a, it's a meaningful part of it.
Tim Savageaux (Managing Director and Senior Research Analyst)
Great. Thanks very much.

One moment for our next question. Our next question comes from Mike Genovese with Rosenblatt Securities. Your line is open.
Speaker 20
Thank you. Just a couple of clarifications at first. The second customer, the one that was almost 10%, the datacom customer, I just want to clarify that that sounds like a webscaler, and I just want to, you know, ask that. Then the second clarification is when you talk about transceivers, sounds like you're also including cables, active optical cables and electrical cables, as transceivers. I just want to check that nomenclature to make sure that cables are in fact transceivers in the way you guys talk about it. Thank you.
Vincent D. Mattera, Jr. (Chair and CEO)
Giovanni, would you take it?
Giovanni Barbarossa (Chief Strategy Officer and President, Materials Segment)
Hey, hey, Mike, thanks for the question. Yeah, absolutely. Yeah, we always include cables, but just to be clear, we have no electrical cables in our portfolio, so it's all optical. We do include cables, absolutely. I think your first question probably was. I, we couldn't hear you very well, but I believe you wanted to, yes, the two-third. When I mentioned two-third, I was referring to hyperscalers. I think that was your question.
Speaker 20
No, I'm sorry. If I could clarify that question. You, you said you had two large customers where orders were expected to go down, and, and one is the, you know, obviously the consumer electronics customer. I just wanted to check that the second one, the datacom customer, that that is in fact a, a hyperscaler.
Vincent D. Mattera, Jr. (Chair and CEO)
Well, electronics was really consumer, you know, consumer electronics, and the communication was datacom. It was large customers to us.
Speaker 20
Okay. Then my next question, my other quick question is the 200G per lane lasers, when do we expect those to be shipping for revenue, within the transceivers or to external customers?
Vincent D. Mattera, Jr. (Chair and CEO)
Well, right now we are prioritizing our internal customer for anything 200G. We, we have design wins with some of our competitors, transceiver competitors. We'll, we'll that will be meaningful only in the second half of the fiscal year.
