Good afternoon, everyone. With me today are Jim Anderson, Coherent's CEO; and Rich Martucci, Coherent's Interim CFO. During today's call, we will provide a financial and business review of the fourth quarter of fiscal 2024 and the business outlook for the first quarter of fiscal 2025. Our earnings press release can be found in the Investor Relations section of our company website at coherent.com. I would like to remind everyone that during our conference call today, we may make projections or other forward-looking statements regarding future events or the future financial performance of the company. We wish to caution you that such statements or predictions are based on information that is currently available and actual results may differ materially. We refer you to the documents that the company files with the SEC, including our 10-Ks, 10-Qs, and 8-Ks. These documents contain and identify important risk factors that could cause the actual results to differ materially from those contained in our projections or forward-looking statements. This call includes and constitutes the company's official guidance for the first quarter of fiscal 2025. If at any time after this call, we communicate any material changes to this guidance, we intend that such updates will be done using a public forum such as a press release or publicly announced conference call. We'll refer to both GAAP and non-GAAP financial measures during this call. By disclosing certain non-GAAP information, management intends to provide investors with additional information to permit further analysis of the company's performance and underlying trends. For historical periods, we provided reconciliations of these non-GAAP financial measures to GAAP financial measures that can be found on the Investor Relations section of our website at coherent.com. Now let me turn the call over to Jim Anderson, our CEO.

Thank you, Paul, and thank you, everyone, for joining us on our call today. It's been a little over two months since I joined Coherent, and I'm more excited today about the potential of this company and the opportunity for shareholder value creation than the first day I joined. I want to start by thanking my predecessor, Chuck Mattera, for his over 20 years of service to the company, including his last eight years as CEO. Chuck's tireless dedication and leadership of Coherent has had a tremendous lasting impact on the company. And on behalf of all of our employees and our Board of Directors, I want to once again thank him for his service and wish him all the best. I'd also like to take the opportunity to thank my new Coherent teammates for the incredibly warm welcome to the company. In these first weeks, I've met with employees at many of our locations across the world. I'm deeply impressed with the exceptional depth and breadth of talent as well as the determination and hard work of my teammates. I look forward to working side-by-side with them to unlock the full potential of the company. Since joining Coherent, I've received a number of questions from employees and shareholders regarding my initial impressions on the business and our long-term strategic direction. I've also been asked about my reasons for joining Coherent and what drew me to this opportunity. Let me start with what I found the most attractive about joining Coherent. Simply put, it was a combination of the innovation this company is driving and the revenue growth potential that's ahead of us. Innovation is the lifeblood of the technology industry and Coherent is a deeply innovative company. Over the course of my career in the tech industry, I've worked at many innovative companies. And I can tell you firsthand that the innovation happening every day in this company is absolutely world-class. Innovation is in the company's DNA. We innovate at a foundational physical level that underpins critical advancements in many of today's most important and demanding growth applications. Innovation is what this company was founded on, and I believe that's why the company has thrived over 50 years. And I want to ensure that we continue to cultivate this culture of innovation for the next 50 years. Of course, innovation is only meaningful if it ultimately has an impact on people's lives and translates into shareholder value creation. The second thing that attracted me to Coherent is our market product position and our ability to impact and drive large secular growth opportunities. The addressable market for our products and innovation is over $60 billion and growing quickly. Coherent is an industry leader across many product lines, and we're driving innovation in secular growth applications that will change how we live and work. One of the most exciting growth opportunities is our optical transceiver technology, which underpins and drives the high-speed connectivity required by new AI data centers. While I believe this is a tremendous opportunity for the company, there are many other examples of secular growth opportunities ahead of us. Opportunities such as next-generation telecom systems, advanced displays, semi-cap equipment for next-gen fabs, industrial automation and robotics, EVs, and many others. We are well-positioned across multiple long-term secular growth markets. My responsibility is to translate our innovation engine and growing market opportunity into market-leading revenue growth, expanding profitability, and industry-leading shareholder value creation. To achieve these goals and unlock shareholder value, I'm focused on three key areas of improvement: number one, our culture; number two, our strategy; and number three, our execution. On the culture front, I love our innovation-focused culture, which we will absolutely continue to embrace, but there's also opportunity for improvements in our culture. We have to move faster and be more agile. Speed is a competitive advantage. To this end, we've initiated changes to simplify our organizational structure, empower our leaders, streamline decision-making, accelerate execution, and ultimately, deliver our innovative products to market faster for our customers. Ultra-change takes time, but I'm excited about some of the early results I've already seen across the company. Moving to strategy. We have a very diverse portfolio of product lines and assets, and we have a significant opportunity to further optimize and focus this portfolio for growth and profitability. To that end, in June, we initiated a portfolio review to assess each element of our product portfolio across the strategic and financial criteria. We plan to use this assessment as the foundation for making investment and capital allocation decisions moving forward. Across our portfolio, we have strong growth engines that need the right level of investment to realize their full growth potential. However, we also have product lines and assets that are nonstrategic and underperforming. We will shift investment to the areas of greatest opportunity, and we will divest or stop investment in underperforming areas. Doing so will drive greater focus, concentrate our OpEx and CapEx dollars on our strongest growth and profit engines, accelerating the deleveraging of our balance sheet, and enhance our EPS and cash flow growth. While I won't be going into the specific areas of investment and disinvestment on today's call, we plan to hold an Investor and Analyst Meeting in the coming quarters that will lay out our strategy for the company. This will include our market growth opportunity, our key technology and product line growth investments and our operational strategy as well as our long-term target business model. Finally, the third area of focus for improvement is operational excellence. I believe we have significant opportunity to improve our operational efficiency and effectiveness moving forward. Let me touch on a few examples of the opportunity ahead of us. After meeting with many of our top customers and partners, it is clear to me that we can improve our revenue growth by engaging our customers in a more strategic way that is less transactional and more focused on building deep multigenerational partnerships. Our customers definitely view us as an industry innovator, but we need to improve our roadmap execution fidelity, accelerating our time to market on key technology transitions and become a trusted innovation partner to our customers. We also need to ensure we're leveraging the broader ecosystem and working more closely with our key partners. Beyond top-line growth, we need to improve our gross margin. Frankly, our gross margin is too low. I believe we should be operating at a consistent, sustainable gross margin level above 40%. On pricing, it's clear we have room for improvement. Our team is implementing a new pricing optimization strategy across our businesses to appropriately balance competitive pricing with fair payment for the innovation that we deliver to our customers. On the cost side of the gross margin equation, we have multiple areas for improvement. For example, we need to improve our product yields, our overall asset utilization, and our make-versus-buy decisions. Gross margin improvement will take time, but we are determined to drive a disciplined roadmap of margin expansion. On operating expenses, we need to improve our return on investment. For R&D, while innovation requires investment, those investments must be focused, efficient, and offer high return. Today, our R&D investment is spread too thin. We will focus our R&D investment on the areas of greatest growth potential and eliminate investment in highly speculative projects that lack a strong business case. On SG&A, we need to drive greater efficiency. We will execute on our in-flight synergy and efficiency programs while finding new ways to better leverage our significant scale. Ultimately, our goal is to increase cash generation. Consistent growth, gross margin improvement and better OpEx efficiency will help. However, we also need to improve our return on capital expenditures. We will align our CapEx investments with our overall portfolio strategy and focus on our areas of greatest growth and profitability. With better operational discipline, I believe we have the opportunity to significantly increase our free cash flow and accelerate our pace of debt reduction and deleveraging. Our near-term capital allocation priorities are: first, to fund our organic growth engines; and second, to deleverage our balance sheet as quickly as possible. I believe the combination of an enhanced culture along with strategic portfolio optimization and operational execution improvements will help put us on a path of sustained market-leading growth, enhanced profitability and cash generation and a strong balance sheet. As I mentioned earlier, I look forward to sharing more details about our plans and specific business metrics and targets at an upcoming Investor and Analyst Meeting. One of my near-term priorities is to fill the CFO role. We're considering both internal and external candidates and making good progress on the search. Once the new CFO is in place, we'll set a specific date for our Investor and Analyst Meeting. I'll now switch gears and provide some brief comments about our fiscal fourth quarter results. Revenue in Q4 increased by approximately 9%, both sequentially and year-over-year, driven primarily by strong growth in our datacom transceivers for AI data-centric deployments. Non-GAAP gross margin expanded by 145 basis points sequentially due primarily to recovery from the transitory issues that impacted our Q3. Non-GAAP EPS grew by 16% sequentially and by almost 50% year-over-year as a result of top-line growth and margin expansion. Let me summarize what we're seeing in our business by end market vertical. In the communications end market, Q4 revenue increased by 10% sequentially and by 19% year-over-year. We experienced strong growth in datacom, where Q4 revenue grew 16% sequentially and 58% year-over-year due primarily to AI and data center demand. We saw strong sequential growth in our 800G datacom transceiver revenue in Q4 and are also seeing increasing orders in backlog for the current and future quarters. We also delivered initial samples of our 1.6T datacom transceivers, which we expect to begin ramping in calendar 2025. Our new datacom optical switch platform is progressing well and is generating significant customer engagement, and we expect to enter customer trials in calendar 2025. Growth in datacom was partially offset by a 6% sequential and 38% year-over-year decline in telecom revenue due to end market weakness. Although we expect the telecom end market to remain weak in the near term, we also expect to ramp our new 100G ZR and 400G ZR+ Coherent transceivers over the course of our fiscal year. Overall, we expect the communications market to be a strong long-term growth factor for the company. In the industrial end market, revenue increased 2% sequentially and 5% year-over-year. Our display capital equipment vertical saw a growing demand in Q4 for Excimer Laser Annealing and related services driven by expanded OLED adoption in the smartphones and the inception of OLED adoption into laptop and tablet computers, with the latter essentially doubling long-term demand for OLED screen area production. In our other industrial verticals, we saw relatively stable revenue in aggregate. While we expect overall industrial end market demand to be soft in the near term, we believe we are well-positioned for growth over the long term, given our multiple growth opportunities in this segment driven by new product introductions such as our fiber laser platform for cutting and our new line being annealing systems for GenAI display fabs. In our two remaining markets, electronics and instrumentation, each of which account for less than 10% of our total revenue, we saw sequential revenue growth, and both end markets remain long-term growth opportunities for us. In summary, about two months in, I'm even more excited about the opportunity to unlock significant shareholder value based on the depth and breadth of our innovation, the size of the market opportunities we address, and the potential to improve our operational execution. We're expecting strong growth in our datacom business over the coming quarters. And while some near-term softness persists in our telecom and industrial end markets, we expect fiscal 2025 overall to be a solid growth year for the company.

Thank you, Jim. Overall, I'm very pleased with the continued sequential financial progress we made in the fourth quarter of fiscal 2024. We delivered a strong quarter with sequential revenue growth and healthy improvement in our gross and operating margins, which drove sequential earnings per share growth. Fourth quarter revenue was $1,314,000,000, representing an increase of 8.7% sequentially and 9.1% versus the prior year. From a segment perspective, networking revenue increased 10% sequentially and by 16% year-over-year. Materials segment revenue increased 17% sequentially but decreased 3% year-over-year, and our laser segment revenue increased by 1% sequentially and by 7% year-over-year. Our fourth quarter GAAP gross margin of 32.9% improved by 255 basis points sequentially and by 437 basis points versus the prior year. Our non-GAAP fourth quarter gross margin of 37.2% improved by 135 basis points sequentially and 132 basis points versus the prior year. Sequential improvements were primarily due to our increased revenue volume and resolution of the transitory margin issues that we cited in the preceding quarter, including the recovery in our datacom AI transceiver yield and resolution of the power failure issue that depressed both of our silicon carbide revenue and gross margin. Our fourth quarter GAAP operating expenses were $339 million compared to $344 million in the prior quarter and $499 million in the year ago quarter. Fourth quarter non-GAAP operating expenses were $266 million compared to $250 million in the prior quarter and $248 million in the year ago quarter. The sequential increase in non-GAAP operating expenses includes year-end bonus and benefit adjustments and term loan refinancing fees. Looking ahead, we plan to continue to be disciplined in managing our SG&A expenses, now ensuring that we invest in our product portfolio. Our fourth quarter restructuring expenses included in GAAP operating expenses were $14 million compared to $12 million from the preceding quarter and $119 million in the year ago quarter. Our restructuring synergy and site consolidation plans are progressing in line with previously communicated expectations in terms of both costs and savings. Our fourth quarter 4.8% GAAP operating margin increased by 296 basis points compared to 1.8% in the prior quarter and by 1,769 basis points compared to an operating loss of 12.9% in the year ago quarter, driven by improvements in both gross margin and operating expense leverage. Our fourth quarter 17% non-GAAP operating margin increased by 191 basis points compared to 15.1% in the prior quarter and by 162 basis points compared to 15.4% in the year ago quarter, driven by improvements in both gross margin and operating expense leverage. Our fourth quarter interest expense was $68 million compared to $73 million in the preceding quarter and $79 million in the year ago quarter. The full year FY '24 GAAP tax rate was negative 7.5% compared to 27% in the previous year. The full year FY '24 non-GAAP tax rate was 20.7% compared to 18.2% in the previous year. Fourth quarter GAAP earnings per diluted share was negative $0.52 loss compared to a $0.29 loss in the prior quarter and $1.54 loss in the year ago quarter. Fourth quarter non-GAAP earnings per diluted share was $0.61 compared to $0.53 in the preceding quarter and $0.31 in the year ago quarter. We generated $162 million in cash from operations in the fourth quarter compared to $117 million in the prior quarter and $182 million in the year ago quarter. Fourth quarter capital expenditures were $100 million versus $93 million in the preceding quarter and $93 million in the year ago quarter. Free cash flow, net of the $49 million of capital funded by the silicon carbide LLC minority interest investment, was $111 million. We paid down $64 million in debt during the quarter and a total of $229 million for all of fiscal 2024. Total debt at the end of FY '24 is $4.17 billion. Unrestricted cash increased to $926 million from $899 million in the prior quarter. Restricted cash set aside for our silicon carbide LLC subsidiary decreased to $858 million from $889 million in the preceding quarter. In summary, moving forward, the company will continue to be laser-focused on investing in organic growth, improving operating leverage, prudent capital investment, and executing on paying down debt. Now I will turn to our guidance for the first quarter of fiscal 2025. Revenue is expected to be between $1.27 billion and $1.35 billion. Non-GAAP gross margin is expected to be between 36% and 38%. Total operating expenses are expected to be between $260 million and $280 million on a non-GAAP basis. Tax rate for the quarter is expected to be between 20% and 23% on a non-GAAP basis. EPS is expected to be between $0.53 and $0.59 on a non-GAAP basis.

Our first question comes from Samik Chatterjee with JPMorgan. You may proceed.

Hi. Thanks for taking my question. And Jim, I look forward to working with you. I guess the first question that I want to throw your way is really in relation to, you said it's early days in terms of the strategic assessment you're doing. Just maybe help us think about what are the sort of early reads you have around the portfolio from there? You talked about core and non-core. Maybe what's the criteria using or the lens that you're looking at from deciding core and non-core? And how much of the sort of implication is on operating the company more efficiently relative to maybe deleveraging the balance sheet in terms of priority of these actions? And I have a quick follow-up if you'll allow me. Thank you.

Yes. Thank you, Samik. Thanks for the question. I appreciate it. Yes, on the portfolio assessment, happy to talk a little bit more about that. I'm really pleased with the work that the team's been doing on this over the last couple of months. Think about the portfolio assessment as really work that we're doing to build a foundation for our strategy going forward. The ultimate goal of it is to really make sure that the company is concentrating all of its assets, whether that's OpEx or CapEx, on the areas of greatest growth and profitability over the long term. And so that's really the ultimate goal. The way we're approaching it is we're stepping back and looking at the entire company portfolio. We're breaking down the company and each one of its individual product line divisions. Then we're grading each one of those on a set of strategic and financial criteria. We're putting each one of the businesses into one of four categories. I'm happy to share a little bit more about that. The four categories are: what do we think are big growth engines for the company moving forward? What are the profit engines? What are the kind of longer-term bets that the company is making? And then what are those businesses that we think are nonstrategic or underperforming? When you say growth engines, those are businesses that we believe are going to drive long-term above-market growth for us. Profit engines are businesses that may be growing a little slower but are generating really healthy levels of profit. Long-term bets are businesses that we're investing in today that have a longer ROI than typical for us but may have a big payoff at the end. The nonstrategic and underperforming businesses are really businesses that just don't fit with the overall portfolio or are significantly underperforming our financial targets. With that foundation built, and that work is really concluding through the course of this month, we'll be taking a set of actions to concentrate our assets and investment on those areas of greatest growth, as I said, and then either divesting or shutting down investment in those underperforming or nonstrategic businesses. Certainly expect to hear more about that from us over the coming quarters. I'm really happy to share more about that at the Investor and Analyst Day that we're planning in the future. I think you also asked about deleveraging the balance sheet. That's certainly a big focus of ours as well. I look at that deleveraging opportunity as really could be driven by two things. To the extent that we do decide to divest any businesses, the proceeds of those divestitures could be used to pay down the debt. But also just setting aside the portfolio assessment, I talked about some of the operational execution improvements we want to drive, really focused on driving better gross margin, better profit margins. Obviously, that yields better cash flow, which would help us accelerate debt paydown, but deleveraging the balance sheet is a key focus as well.

Got it, got it. And if you'll allow me for a quick follow-up, I know you talked about gross margins being sustainably above 40% is how you're thinking about the business. If you sort of look at the gross margins today, do you think the effective sort of the biggest gap between where your aspiration is and what sort of the companies delivering today? Is that pricing or is that sort of these underperforming businesses? Once that's sort of done and dusted, you sort of get back to that sustainable range? Maybe just help me in sort of what's the biggest gap you're identifying between where the company should be and where the gross margins are today.

It's a great question, Samik. I would say it's really a combination of underperforming businesses that have gross margins significantly below our corporate average. Additionally, there are opportunities regarding pricing and cost structure. I mentioned this briefly in my prepared remarks. I believe we can enhance our pricing discipline moving forward. Some of the ideas I have are similar to those I implemented in previous companies, where we used advanced pricing analytics and strategies to ensure competitiveness while achieving fair value for our innovations. We have initiated a pricing initiative aimed at improving our pricing discipline, which I expect will lead to gross margin improvement. Regarding costs, there are several areas within the company where we need to focus on improving our cost structure; I noted a few in my prepared remarks. We have opportunities for improvement in product yields, asset utilization, and making better make versus buy decisions. We need to leverage the larger ecosystem when appropriate to ensure we are applying our assets where we can drive increased differentiation or provide significant advantages to our customers. These are the three key areas I’m considering for gross margin improvement.

Great. Thank you. Thanks for taking my questions.

Thanks, Samik.

Thank you. Our next question comes from Jeff Koche with Raymond James. You may proceed.

Yes, thank you. This is Jeff Koche from Raymond James. I wanted to delve deeper into the gross margin. Could you discuss the trajectory you foresee for reaching the 40% or higher range? Additionally, I would like to hear your thoughts on the decision to buy versus make, especially considering that one of your competitors mentioned last night that they have indium phosphide lasers booked out through the end of 2025 at 200G per lane. Please provide an update on your in-house production strategy regarding this. Thank you.

On the first part of your question, the glide path, that's definitely a topic that we want to cover at that Investor Day that I mentioned. We'll be scheduling that in the coming quarters. And what we'll do is, as part of that Investor Day, it's not just lay out the company's strategy but give an overall business model target for the company in a sense of what our timing is of the time frame to achieve that business model target, including the gross margins. But this will definitely be a key focus area for us moving forward. Gross margin improvement takes time. Whether it's pricing or cost reductions, those take work. But we're determined to drive a steady roadmap of improvement moving forward. You'll hear more about from us around the timing of those gross margin improvements in the quarters ahead. And then on the second part of your question, make-versus-buy, look, I think the way to think about this is one of the benefits that Coherent has versus our competitors, and it's a benefit that our customers see every day, is there's a number of places where we're vertically integrated. We build, for instance, not just the datacom transceiver, but we build a number of the components that go into that transceiver. To the extent that that provides us differentiation or faster time to market or generates real value for our customers, that's fantastic and we will continue to do that. But I want to make sure that we're careful about not just building it internally for the sake of building it internally, but to the extent that there's external providers or an ecosystem that we can leverage that's competitive in terms of technology and cost with the internal option, I'd rather use those resources to focus on areas that we can truly differentiate and add value for our customers. I just want to make sure that we're being objective moving forward on make-versus-buy and being smart about how we leverage.

Got it. Appreciate it.

Thanks, Jeff.

Our next question comes from Tom O'Malley with Barclays. You may proceed.

Hi Jim. Thanks for taking my question and great to meet you. I kind of wanted to ask on the optical opportunity and the transceiver business in general. I realize you just joined the business and there were a lot of metrics kind of floating around, and I'm sure you don't want to marry yourself to any of those right away. But in your initial days at the business, clearly, the big growth engine Coherent has been this 800G ramp and then in the future, potentially the 1.6T ramp as well. But when you look at kind of what was advertised to you when you were first looking at this job and then kind of got underneath the covers and looked at that optical opportunity, could you maybe speak qualitatively about your expectations in that business? I understand that you'll have an Analyst Day and maybe put some more numbers on it, but just broadly, your feelings on that business and what that growth engine could look like for Coherent over the next couple of years? And then I had a follow-up.

Yes. Thank you, Tom, for the question. Yes, the short answer is it's better than I thought before I joined the company. I had a sense of Coherent as a leader in optical transceivers specifically for datacom. Obviously, there's tremendous build-out happening now with AI data centers. I have my own sense of what that sort of growth trajectory would look like, before I joined the company. It's stronger than what I had thought. We've seen, just over the last, I would say, four to six weeks as I've spent a lot of time with our top customers across all of our different product lines, but especially in our datacom business, I've gotten a much better sense for the opportunity that's in front of us, and I would say it's a very strong opportunity. We continue to see demand strengthening, forecast strengthening, billings, backlog. Yes, we knew this as a really key growth area for the company. The 800G ramp is very exciting for us. I was really pleased with the team's execution on the 1.6T. They delivered samples of 1.6T just over the past few weeks, month. I think that was a key milestone for us, and we're looking forward to ramping 1.6T next year. It's an exciting growth area for the company. I will say that, but I also want to make sure that we recognize that there are other growth areas within the company as well. I know I'm excited about datacom and AI data centers. But there are a number of other good areas of growth within the company. I mentioned a few of them in my prepared remarks. One of the strengths of Coherent is not just the innovation that I talked about but the wide portfolio of growth opportunities across our other businesses as well. I think that makes for a really strong long-term portfolio, a diversified portfolio of growth moving forward. So, and yes, definitely, I'll share more thoughts on all of those growth engines at Investor Day.

Perfect. And then the second one is just a little more tactical in regards to kind of what we heard last night from your competitor who was talking about an improving telecom market into the September quarter. It sounded as though you were a little more cautious. Just could you describe what you're seeing from those customers just in the short term? This is less of a long-term strategic question. But just a sense check on, are you seeing that market recovering with legacy products? Are new product introductions kind of picking up? That's what was kind of echoed last night, newer products growing at customers. Just the puts and takes on what you're seeing in the telecom market just, because visibility has been pretty bad, inventory levels have been high. Where are we at in that correction kind of off the bottom? Thank you.

Yes. Thanks, Tom. I'm going to separate it out into just purely end market comments versus I'll come back and talk about some of the new products that we have ramping here. So just purely end market, yes, I guess we're taking a more cautious view on the market. I don't believe that we're completely out of the woods as an industry on the telecom market. Significant destocking has happened in that market and that's good, right? The telecom market built up significant inventory. I think most of that destocking is largely behind us. But I think there are still pockets of inventory that are out there. Our whole look on the telecom market through the next, I would say, at least six months and probably into the following six months, is a bit more of a cautious outlook. Now, it could be that we're wrong and it ends up being better, or stronger than that, but we're taking a more cautious view on that. Now that's all end market comments. Now set that aside, I'll switch over to Coherent specifically. We do have a number of products that are ramping that are pretty exciting. The number - and I mentioned in the prepared remarks, both the 100G and then the 400G ZR and ZR+ that will ramp throughout the course of this year. Obviously, since you're ramping over the course of this year, they have a bigger impact in the second half of our fiscal year. I think that we do have some growth tailwinds behind us in terms of our own products. But I think in terms of the market, we're expecting that to continue to be soft.

Great. Thank you. Thanks for taking my questions.

Thanks, Tom.

Thank you. Our next question comes from Meta Marshall with Morgan Stanley. You may proceed.

Great. Thanks. I'll start with a question non-AI just to focus on some other areas of the business. The material business looked to have kind of better-than-expected performance throughout the quarter. Was some of that just improvement on silicon carbide yields that had kind of encumbered last quarter? Were there any other markets worth calling out that improved there? And then maybe just as a second question. On the datacom side, I know the focus is on 400G and up, but just any recovery you guys are seeing in kind of demand for the non-AI speed transceivers? Thanks.

Thank you. On the first part of your questions on the materials business, yes, we did see some pickup in the materials business from Q3 to Q4. You're right, a good chunk of that was the production issues we had on silicon carbide in Q3. We were able to catch up on those issues or catch up on that demand in Q4. So some of that sequential gain is certainly due to that silicon carbide catch-up. And then on the second part of your question, I called that it was on datacom, but I didn't quite hear the end of the question. Would you mind repeating the end of that datacom question?

Yes, just demand for kind of the non-AI speeds or the kind of sub 400G. I know that had been an area of more depressed demand, but if you're seeing any changes there.

Got it, okay. The sub 400G. We're expecting that to be relatively stable. So, we don't expect to see any huge growth from that or a huge decline. We're modeling that moving forward as relatively stable.

Great. Thank you so much.

Thank you. Our next question comes from Karl Ackerman with BNP Paribas. You may proceed.

Yes, thank you. Jim, you spoke about the need to have less transactional revenue and the ability to improve pricing going forward. Given your innovation and leadership in high-speed optical transceivers, could you discuss the breadth of hyperscale engagements within datacom? And whether this customer demand is resulting in extended volume commitments, and order visibility provided to you so that you may enable those customers to meet their data center build-outs? Thank you.

Yes. Thanks, Karl. So definitely, we're seeing - we have a very good breadth of customers. If you look at 800G, our breadth of customers continues to grow. It's grown on a quarter-over-quarter basis in terms of those customers that are ramping 800G and are in full production. The breadth of customers feels really good about and continues to grow. Then, on the second part of your question around extending visibility, yes, our visibility or the other way to look at it is our order book has continued to improve over the last 90 days. Especially over the last, I would say, the last six to eight weeks, it has certainly improved. That has given us visibility not just through the end of this calendar year, but into the first half of next calendar year, so really through the rest of our fiscal year here. That order book continues to strengthen for the datacom business, which we view as very positive. We are definitely focused on making sure we meet that increasing demand.

Thank you.

Thank you. Our next question comes from Vivek Arya with Bank of America. You may proceed.

Thanks for taking my question. Jim, you mentioned the strong order book for your optical transceivers extending several quarters. I'm curious, are you seeing any impact at all, positive or negative, because of changes in NVIDIA's product schedule or does that have no impact? And then just given the strength in the order book, how does the pricing and gross margin shape up when you look at the next several quarters? Do you think it can improve from here? Or do you think that margins in this business may still be dilutive to the overall business?

Yes. Thanks, Vivek. On the first part, on the part that was about the order book, yes, we continue - as I said, we continue to see the order book strengthen. I think you asked about a particular customer. I can't comment on that particular customer or really any particular customer. But I can say that in aggregate, we're continuing to see, again, the order book strengthen and demand growing, which is good. On the pricing and gross margin, in general, what we would usually see in the transceiver market is the newer speed grades like 800 and then soon to be 1.6T generally carry higher gross margins than the older speed grades, right? The older speed grades usually become commoditized over time. To the extent that we're ramping the newer speed grades, that's certainly a tailwind for us. A lot of my comments earlier on gross margin are really focused at the aggregate company level, not just in datacom but at an aggregate company level. I believe that there's opportunity for us to improve our pricing discipline to have a better optimized pricing strategy across the company, across all of our product lines. Then also, the number of cost structure improvements that I think the company has the opportunity to improve, not just in datacom but across some of our other product line as well.

And for my follow-up, so you're guiding the current quarter roughly, kind of flat sequentially. What are the puts and takes from the different segments? And I know you're not guiding to December, but should we assume that those same end market trends follow in December also? Or do you think that there is the prospect for some sequential improvement as we look at December just from a broad end market perspective? Thank you.

Yes, Vivek, on the September quarter, the one that we currently guided, yes, we guided roughly flat sequentially. We would expect the datacom business, as we're just talking about, we would expect the datacom business to be sequentially up. But some of our other businesses tied to the telecom and the industrial markets to be sequentially either flat or sequentially down. That offsets some of the datacom growth. If you look at the midpoint of our guide, obviously, our guide is a range, right? That is what we're seeing for the current quarter that we're in. For the December quarter, I'll probably save those comments until the next earnings call, we'll give more insight into what we're seeing in the December quarter, and maybe into the beginning of the next calendar year as well.

Thank you.

Thank you. Our next question comes from Atif Malik with Citi. You may proceed.

Thank you. This is Papa Sylla for Atif. Thank you for taking my question. I guess my first question was around the industrials business. I guess just looking at it sequentially, we saw a little bit of a deceleration versus last quarter. So we were just wondering if you can touch a little bit on the percentage there or perhaps just touch on A, that last quarter, some difficulties such as precision manufacturing, EUV, semicap back-end and how they are doing this quarter?

Yes, thanks for the question. Yes, on kind of the broad base of industrials in aggregate, we did see a little bit of sequential improvement in aggregate in the industrials from Q3 to Q4. But moving into the current quarter, as I just mentioned on a prior question, we're assuming that both the telecom as well as the industrial space are, they're kind of flat sequentially, or there are some segments that are sequentially down. That offsets - we're assuming that offsets some of the datacom sequential growth that we're expecting in the current quarter.

Got it. And for my quick follow-up, I wanted to touch a little bit on the AI front, on the laser front of things for 1.6T. So I guess our understanding is that from an industry-wide perspective, all three technologies, so VCSEL, EML, SIFL - have their own pockets of demand. From your end, can you touch on engagement across those three and kind of what those mixes look like currently? And then what they might look like maybe two, three quarters down the line?

Yes. I think one of the great things about Coherent is, we have a really wide portfolio of technology. We develop our own VCSELs, we manufacture our own VCSELs. We do the same in EML. Indium phosphide, we develop and manufacture in-house. We both develop and manufacture a number of those lasers in-house. Where it makes sense, we also source some of those lasers externally as well. For 1.6T and any technology beyond that as well, we will always make the best use of whatever we think is the best technology to bring the most advanced, most innovative products to market for our customers. Whatever gives us the biggest technical advantage versus our competition and the biggest differentiation for our customers, we will always select that technology, whether it's developed in-house, or whether we source it externally, we'll select the best technology that benefits our customers. So I think, I probably won't give any prognostication on 1.6T and how much of it will be VCSEL versus other technologies. But we'll probably share more about that as we get closer to 1.6T production ramp.

Got it. Thank you.

Thank you. Our next question comes from Ruben Roy with Stifel. You may proceed.

Thank you. And hi, Jim. I wanted to - I know you had a lot of questions on strategy and I appreciate the commentary high level, Jim. I wanted to just maybe talk about pricing optimization one more time. You talked about some successful turnarounds that you've had, and I've watched the last one, which was tremendous in short order. I'm just wondering if you could comment a little bit, given that the breadth of products, end markets, customers, et cetera, is a lot different. I think at Coherent then at the last turnaround that you were working on. Just how are you thinking about timing? Is this a multiyear strategy from an optimization strategy to get some of those margins that you want to get to? Any kind of high-level commentary on that would be helpful.

Yes. Thanks, Ruben. Look, businesses - Coherent is a different business. Every business has its own dynamics, and Coherent itself has a wide range of different businesses within its portfolio. So it's a little bit different business-by-business. As I spend time with both our business leaders, our general managers, our sales team as well as time with our customers, I do think there's opportunity for us to be better in terms of our pricing discipline and how we price our products in the market. Again, finding and striking that right balance between being competitive in the market but making sure we get paid for the innovation that we drive. There are some approaches, strategies, tactics and analytics that I've used in my past across multiple different businesses. I think our universal and can be applied to some of the businesses within Coherent as well. That's certainly what we're working on. We have kicked off already a bigger pricing optimization strategy work that we're driving across the company. That does take time. It's not something that turns on like a light switch. Some of those initiatives take longer time to achieve. Some can provide short-term benefits. But there's a wide range of initiatives that we're beginning to drive, and those yield benefits over time. As I mentioned earlier, when we get to the Investor Day and we give our longer-term business model targets, including gross margin, we'll give some sense about what we think the progression towards those business model targets, including gross margin, will be over time.

Very helpful. Thanks, Jim. I guess just a quick follow-up. It sounds like you're saying that you started some of these actions. Are there any other strategic actions that you've implanted currently? Or is most of it on the come?

Definitely, in the category of gross margin expansion, we've initiated a number of, as I mentioned, pricing optimization strategies. But we're also working on product cost. We've kicked off a number of focused product cost activities. That's something we're driving with equal focus on how we drive better product cost structure within the company. Given that we're a manufacturing company, there's a lot more - there's a lot of knobs for us to turn in terms of driving better cost structure, whether it's better asset utilization, higher yields for our products, et cetera. There's a number of different places we're focused to drive better product cost structure moving forward.

All right. Thanks.

Thanks, Ruben.

Thank you. Our next question comes from Jack Egan with Charter Equity Research. You may proceed.

Hi, guys. Thanks for taking the questions. I just had one other follow-up. So last quarter, you mentioned a 30% increase in bookings for the laser segment, but it's still - revenue-wise, it's still been kind of hovering in the $350 million, $355 million range for the past three quarters. So I was just curious, is that due to those various positives and negatives in the industrial and telecom sectors or markets kind of offsetting each other? Or is there anything else at play there?

Yes. Thanks, Jack. It's actually due more to the time from when a booking is made in lasers to when it's shipped. Those are generally longer lead times, and so it has more to do with just the natural lead time of that business. There's latency from when those bookings are placed until when the product is actually shipped. So it's more about just the natural lead times of that business.

Got it. Okay. And then with the silicon carbide CapEx kind of out of the equation now, I was wondering where, are your CapEx priorities now other than expanding 800G?

Yes. I would say the number one priority in terms of CapEx and setting aside silicon carbide is making sure that we have the capacity in place to support the growing demand that we're seeing in the datacom business. Right now, 800G capacity, but we're also building out 1.6T capacity as well and making sure we're ready for that ramp. Yes, I would say that's our priority one right now in terms of capital expense.

Great to hear.

Thanks, Jack.

Thank you. Our next question comes from Ananda Baruah with Loop Capital. You may proceed.

Hi, yes, thanks, guys. Good afternoon. Thanks for taking the question. Yes, Jim, great to meet you and look forward to working with you. Just one for me. Do you have any thoughts, Jim, on this is a transceiver question. Do you have any thoughts, early thoughts on potential for share gains, kind of share gain percent over the next couple of years? Have you guys yet begun to see the big data center customers begin to sort of index more towards U.S.-based transceiver producers? Thanks.

Yes. Thanks, Ananda. That's a great question. As I have spent time with some of those large data center CSP customers, I think there's clearly opportunity for us to gain share at those customers, due to a number of different dynamics. When you look at Coherent, not only are we a technology leader in transceivers, and I think a technology leader that you can rely on over the course of multiple generations, historically moving forward, but we have an incredibly resilient supply chain. From supply chain resiliency, we are the most resilient supply chain in the industry. Our big data center datacom CSP customers are, if they haven't recognized that already, they're definitely having more appreciation for that. I think the combination of our technology and supply chain resiliency gives us the opportunity to win significantly more share of wallet with those big customers over the coming quarters and years. Thanks for the question, Ananda.

Yes, thanks for the context.

Thank you. I would now like to turn the call back over to Jim Anderson for any closing remarks.

Thank you, operator, and thanks again for everybody joining us on our call today. To wrap it up, I'm super excited about the opportunity ahead of us at Coherent. I want to once again thank all of my new Coherent teammates for all their hard work, dedication and all the innovation they drive every day. While we have many strengths, we also have areas of opportunity for improvement, to translate our incredible innovation engine and growing market opportunity, be it to outstanding shareholder value creation moving forward. Thanks again for your support and look forward to updating you on our progress moving forward.

Thank you. This concludes the conference. Thank you for your participation. You may now disconnect.
