Welcome to MACOM's Second Fiscal Quarter 2025 Conference Call. This call is being recorded today, Thursday, May 8, 2025. At this time, all participants are in a listen-only mode. I will now turn the call over to Mr. Steve Ferranti, MACOM's Vice President of Corporate Development and Investor Relations. Mr. Ferranti, please go ahead.

Thank you, Olivia. Good morning and welcome to our call today to discuss MACOM's financial results for the second fiscal quarter of 2025. I would like to remind everyone that our discussion will include forward-looking statements, which are subject to certain risks and uncertainties as defined in the Safe Harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those discussed today. For a more detailed discussion of the risks and uncertainties that could result in those differences, we refer you to MACOM's filings with the SEC. Management statements during this call will also include discussion of certain adjusted non-GAAP financial information. A reconciliation of GAAP to adjusted non-GAAP results is provided in the company's press release and related Form 8-K, which was filed with the SEC today. With that, I'll turn over the call to Steve Daly, President and CEO of MACOM.

Thank you and good morning. I will begin today's call with a general company update. After that, Jack Kober, our Chief Financial Officer, will review our Q2 results for fiscal year 2025. When Jack is finished, I will provide revenue and earnings guidance for the third quarter of fiscal 2025, and then we will be happy to take some questions. Revenue for the second quarter of fiscal 2025 was $235.9 million and adjusted EPS was $0.85 per diluted share. We ended the quarter with approximately $682 million in cash and short-term investments on our balance sheet. The diversity of MACOM's end markets, product portfolio and global customer base continues to provide us with great opportunities for growth. Revenue by end market were as follows: Industrial & Defense was $98.5 million, Data Center was $72.2 million and telecom was $65.2 million. Telecom was up 18% sequentially, Data Center was up 11% sequentially and I&D was up 1% sequentially. Our I&D and Data Center quarterly revenues achieved record levels. Our Q2 book-to-bill ratio was 1.1:1. Notably, this was the fifth consecutive quarter of strong bookings and we are pleased our backlog is at a record level. Our turns business or orders booked and shipped within the quarter was around 20% of total revenue. We believe our growth is driven by our new products gaining market share, as well as positive secular trends in certain segments of our three major end markets. Now, turning to the end markets. First, Industrial & Defense demand continues to grow, driven by the U.S. and international DoD system upgrades in radar, EW and communication systems. The need for higher frequencies, higher power levels and higher levels of integration within the defense electronics sector plays directly to MACOM's strengths and enhances our addressable opportunities. Outside of the aerospace…

Thank you, Steve. Our Q2 results reflect record revenue levels and strong financial performance, building upon our steady growth in revenue, increased operating income and ongoing cash generation. Our operational performance has allowed us to maintain a strong balance sheet while continuing to generate cash, which we believe positions us well. Fiscal Q2 revenue hit a new quarterly record of $235.9 million, up 8.1% sequentially based on growth across all three of our end markets. Notable double-digit sequential growth within data center and telecom were the primary drivers. Our overall book-to-bill ratio for Q2 was again, above one, with customer orders exceeding our revenue by approximately 10%. Adjusted gross profit for fiscal Q2 was $135.6 million or 57.5% of revenue, in line with the past few quarters. Total adjusted operating expense for our second quarter was $75.8 million consisting of research and development expense of $50.4 million and selling, general and administrative expenses of $25.4 million. The sequential increase in adjusted operating expense compared to Q1 was primarily driven by higher R&D and marketing costs, as well as employee-related costs associated with calendar year payroll tax resets and variable compensation. As we are scaling the business, we have added new capabilities and resources primarily within R&D functions, including those from the recently-completed and previously-announced ENGIN-IC acquisition. I would like to note that we remain very focused on controlling our OpEx as we continue to grow our revenue. Depreciation expense for fiscal Q2 2025 was $6.8 million, compared to $6.7 million in Q1 2025. Adjusted operating income in fiscal Q2 was $59.8 million, up 8% sequentially from $55.4 million in fiscal Q1 2025. For fiscal Q2, we had adjusted net interest income of $6.4 million, which increased $500,000 sequentially from $5.9 million in Q1. Our adjusted income tax rate in fiscal…

Thank you, Jack. MACOM expects revenue in fiscal Q3 ending July 4th, 2025 to be in the range of $246 million to $254 million. Adjusted gross margin is expected to be in the range of 56.5% to 58.5% and adjusted earnings per share is expected to be between $0.87 and $0.91 based on 76.5 million fully diluted shares. We expect sequential revenue growth in all of our end markets. We anticipate that Industrial & Defense will lead with approximately 10% sequential growth followed by Data Center at 5% sequential growth and telecom slightly up sequentially. As Jack noted, we acknowledge the increased uncertainty in the markets. Nevertheless, we have an amazing product portfolio, a sound long-term growth strategy and we continue to focus on execution to capture market share. I would now like to ask the operator to take any questions.

[Operator Instructions] And our first question coming from the line of Tore Svanberg with Stifel. Your line is now open.

Thank you and congratulations on the strong results here. Steve, so your data center business is on track to growing, I think, close to 50% or above 50% this fiscal year. You've talked about this business being quite volatile. What's your current read on the market and do you think this growth momentum can sustain going into fiscal '26?

Great. Thanks for the question, Tore. And you're right to observe that our data center business has been growing. In fact, it's been it's really been growing since 2018 year-on-year. More recently in our fiscal 2023, we had about 6% year-over-year growth and then in our fiscal '24 about 35% And here, we are halfway through fiscal 2025 and I would say we're on track to be somewhere in the mid-40% year-over-year growth range. A lot of that is coming from the movement within the data center to go to the higher data rates. A lot of that is being driven by the adoption of the 100G per lane platforms across multiple data rates, including 800-gig SR8, 400-gig SR4 and even some early adopters of 1.6T. Generally speaking, we think those trends will continue. And then as a tailwind, we do see that the industry is beginning to seriously look at LPO. And I think the industry sort of hit a milestone in March at OFC when it ratified the LPO standard within the MSA. And so, just to remind everybody, there's an industry organization that's helping define the interface standard for LPO solutions and a specification was released in March. It's basically an ethernet-based single mode link at 100G per lane and it allows the switch and the NIC in the module manufacturers to understand what the interface specs are. And so, now that that is settled, we believe over the next year to two years, LPO will become a mainstay in a variety of applications. And we believe if that happens, then we could continue to see strong growth. Now, with all that said, I would just also highlight as I did on my script, this is a very volatile market. We have seen examples of fast-moving ramp ups and ramp downs during this year, and we would expect that type of volatility to continue. So, from our point of view, we have to continue to be on that leading edge of high-data rate. We have to introduce new products and I talked about our 200-gig photodetector, how we're now mounting those devices on our TIAs. And we're also working on lasers. On our last conference call, we talked about the efforts that MACOM is making with CW lasers. So, a lot of moving parts, I would probably not recommend investors or analysts to expect continued growth at these growth rates. We think that over the long-term, things will settle down into a more rational growth rate.

That's great color. Thank you for that. And as my follow-up, I had a question on the Wolfspeed RF fab transition. So, we're about six months away here. It sounds like things are ahead of schedule. So, just trying to get an understanding of some of the gross margin impact as that transition happens here in about six months, especially given your comment that things are running ahead of schedule.

Yes. And maybe, we'll do a two-part answer. I'll take the front end of that with some comments and then Jack can also add some commentary. So, when we originally acquired the business, we highlighted to investors that the overall business had very low profitability. the gross margins were very low. And we did a lot of work before we closed the deal to restructure and adjust the OpEx, so that on day one, the business would be accretive to MACOM's P&L, although it would be dilutive to the gross margins. And you saw that come into fruition, back in 2023 when we -- on that first quarter, where we had a step back in gross margins. Since then, over the past 17, 18 months, we have been incrementally improving the gross margins. And we always had a goal that when that fab transferred, it would be neutral or positive to our gross margins. And I would say that, today, we're not there. I think we have more of a gap to close in terms of looking at yields, looking at throughput cycle times and things of that nature. And so, I do think that there is a gap. It's not easy for us to say what that gap is right now, because we're not running the fab. We only have our models, which I think are very good. So, I would say that we still have a little bit of work to do and certainly, we have more time to do that as you highlighted the fab would be conveying maybe between now and year end. and that work will continue after the fab conveys. And the last thing I'll say before I turn it over to Jack is, we established a model, where this transaction would pay for itself in three years. We are on or ahead of plan to make that happen. So, the cash generation from this transaction has been very positive. Jack, do want to go a little deeper on gross margins?

Sure. I think I would just add, as Steve had mentioned in his prepared remarks, there is increasing demand on the fab down there. We are looking to expand the capacity. And I think as things continue to transition for us, where we can take effectively more control when the fab is under our direction, we'll be able to make further improvements from an overall gross margin perspective. So hopefully, that helps more to come as we work our way through the remainder of the calendar year.

Thank you. And our next question coming from the line of David Williams with the Benchmark Company. Your line is now open.

Hey. good morning and thanks for taking my questions here. I guess maybe, Steve, I've heard you talked a little bit about the volatility and the changing trends that happened within the data center. But I guess, from a bigger picture, are you seeing the budgets kind of play out this year? And maybe, what are your expectations for next year in that data center, especially where you're positioned and where do you think you're going to see the largest growth opportunities there, maybe by technology?

Well, we do see continued trends that the ISPs are continuing to invest in data centers. So that's a positive trend that we think will continue into next year and even the year after that. That's number one. Number two, we also are seeing a high level of innovation within the platforms that we service and you hear things like CPO and NPO, and LPO and all of these different variations of how to connect high-speed data. And as a merchant supplier, we're sticking ourselves right in the middle of that conversation, whether we're talking with somebody that's in compute or whether somebody is building a server or a switch or a module. And we want to bring to them not only high-speed electrical solutions, but also optical solutions. So, whether they make those short reach connections using copper cable or optical cables or fiber optic links, we want to be involved in that. And so, we think that the SAM within the data center for MACOM is growing. And so, because of that, we think that there's still tremendous room to grow in the future. But we of course have to pick and choose our battles. We have to make sure we have the right product at the right time. We have to remain competitive on a lot of different levels in terms of performance, cost, producibility, time to market. So, it's an exciting place to be. We're not short of opportunities and we do think that we will continue to grow and gain market share in the data center.

Great. Thanks for that color. And then maybe, just secondly, the satellite business, it sounds like you're continuing to gain some nice traction there. Just wonder if you can kind of size the magnitude of what you think your opportunity is there. And maybe, just any color around how quickly that market is developing would be helpful. Thank you.

Thanks. Thank you, David. So, the SATCOM business for MACOM is continuing to grow. It's been growing over the past few years and we expected more good things in the future. And maybe, I would just highlight an example of increasing our SAM within that market by adding new product lines. And I talked about the Opto-Amp, which is a high-power optical amplifier that's suitable for gateways or onboard satellites, to have a free space optical link, which will not only provide data streaming from satellite to satellite, but also location, position and other overhead that's necessary to run the network. So, we're very excited about doing things like that, bringing unique, difficult products to bear, helping our customers find solutions. And I think that Opto-Amp is just a really good example of adopting, new technology coming up with unique circuit designs, so that we can support our customers. The other thing I'll highlight in the SATCOM market, which is historically a lot of the links have been at Ku-Band, which is about a 10 to 13 gigahertz, maybe 14-gigahertz frequency. And what we're seeing is a lot of the newer, satellite networks and the connectivity is moving up to Ka-Band, which is, in that 30-gigahertz range, as well as Q-Band and V-Band, and to throw another one out there, W-band. And so, these are all very high frequencies, 40 gigahertz, 50 gigahertz and even 65 gigahertz, 70 gigahertz. And so, there are very few companies, in the industry that can provide chips for these networks. And in addition to that, there's very few companies that can build modules or subsystems, or help a customer close a link at these frequencies and we're one of those companies that can do that. And so, when we go to market and we think about the SATCOM opportunity, we think about optics, we think about power, RF power and we think about very high frequency. So, these play to our strengths. So, we think that the opportunity size is actually very attractive. We're always hesitant to put a number on it, because it depends on where you draw the line. But I would say that we are continuing to invest our R&D dollars to support the opportunity.

Thank you. And our next question coming from the line of Karl Ackerman with BNP Paribas. Your line is now open.

Yes. Thank you. Steve, I'd like to go back to that comments or comments on SATCOM. I was hoping you could address the timing of the previously-announced 55 million SATCOM and whether you have greater clarity on the opportunity for the program to expand additional 25 million. I guess as you address that perhaps you could discuss the breadth of design wins and size of the SATCOM business within your telecom business today? And I have a follow-up please.

Sure. So, the large contract that we announced about a year ago, we explained that that sort of two phases. The first phase is an R&D phase, where we were doing a wide range of chip developments. I think there's between 10 and 15 specific chips that we are designing for that platform. We're pretty much, I would say, three quarters through that phase, things look great. We're having some amazing results from our chip designers and they're hitting the specs they need to hit and things like that. And now, we're moving into more of a build phase and getting our EMs or engineering models built up and delivered to customer and going through sort of a certification phase. What will follow after that will be a ramp in revenue and production. We expect that that's probably about six months away. And so, probably starting towards the end of this year, beginning of next year, depending on how things go. And so, I would say generally, that large program is on track. I don't want to comment on the potential follow on of that 25 million additional module. And so, I really just don't want to comment on that. At this point, we're very focused on executing the program we're on and that if there's announcements that need to be made on that later, we'll certainly do that. But I would say generally speaking, that program is on track and the team is doing a great job. In terms of some of the other questions you had about the overall size and other opportunities, I'll just say that we're continuing to see new companies enter the market. They have different approaches to solving communication, sensor and networking problems and we are again, inserting ourselves and providing lots of semiconductor content. And perhaps one example would be, you're starting to see more and more networks adopt direct to cell connectivity, which means the LEOs or the MEOs are going to have a connectivity directly to your cell phone. And so, if you can imagine that MACOM is a big supplier into the cellular infrastructure market, we understand, what's necessary to have an efficient transmitter or receiver, in a base station and we're bringing that same knowledge to bear to our satellite customers and they love it. They like the fact that we understand the protocol, we understand all the different bands, we understand how to make these products work and we have the space heritage. So, they're embracing us to help them solve the direct to cell issues.

Got it. Thank you for that. I want to pivot to defense. You indicated that industrial & Defense should grow 10% sequentially. Perhaps both of those markets are growing with industrial maybe appear to be bottoming. But within defense, I was hoping you could address what your exposure is to European defense spending directly or indirectly. I ask given your very large defense business and certainly growing government interest to expand defense spending globally. Thank you.

Thank you. So, our direct exposure to European defense spending is growing and we see that as a good thing. And a part of our long-term growth strategy was to build out a stronger presence in Europe and really, the catalyst for that was the acquisition of a small wafer fab based right outside of Paris in France. And that has given us a great platform to work with customers across Europe to support their programs. Now historically, that business had about 50% of its revenue came from foundry business, meaning the customers design the chips and the other 50% was product based. The 50% that was foundry based was primarily coming from European defense contractors. And so, when we completed that acquisition, it gave us a really sort of a running start in an instant relationship with a lot of companies we hadn't done business with. And so, over the last two years, we've been developing those relationships. We've been improving the performance of the MESC facility. We've been introducing a lot of our U.S. based technologies, including optical technology and GaN on Silicon Carbide. And so, all of these things are starting to fall into place and will generate future growth. And as I highlighted in my comments, we recently received a very significant pilot order to support a large European radar program. and so, we expect more good things to happen. We expect that exposure will increase. There is not -- in Europe, they do not have the depth in my opinion, that the U.S. has in terms of the capabilities on the RF and microwave side. So, they're looking for companies like ours to set up shop and support them and that is exactly what we plan on doing. And I'll add that we will use our MESC facility as a foundation to build higher level solutions for our customers, not only on the defense side, but also on the space side.

Thank you. Our next question coming from the line of William Stein with Truist Securities. Your line is now open.

Great. Thank you for taking my question. Congrats on the good results and outlook. I'd like to start by asking about the telco end market broadly. It seems to me by my less-trained eye that this was the end market that drove the majority of the upside in the quarter. And yet I recognize that revenue performance in that end market over the last few quarters has been relatively depressed. So, was this a matter of sort of true end market demand or was this more a matter of inventory through the supply chain having been consumed and we're starting to grow from that? Maybe, you could clarify which of those two dynamics is really driving this?

Sure. And maybe, just a few words on the telco. So, you're right that, it had a great quarter in Q2. I would say that if you compare our current run rate, we should start to get into a range, where we're having record telecom revenues on a yearly basis. So, we're very happy about that. From a market segment point of view, I would just highlight that the 5G market generally, if we listen to the major OEMs, they're saying that business is relatively flat. Nevertheless, we continue to grow our business by gaining market share, introducing more products to the same customers. So, our that has been a tailwind for our 5G business. Second, we put SATCOM inside of the telecom numbers, so that's also a big driver of some of the growth that we're seeing. And regarding inventory, I would say that there are some segments of the telecom market that have pretty much gone through and burned down their inventory. One of them would be cable infrastructure. we're starting to see an increase in orders, albeit at a very low level, but increases in orders from our cable infrastructure customers here in the U.S. And also, we're starting to see a slight growth in sequential growth in 10G PON. The last item I'll highlight within telecom is a segment we call metro long haul, which is generally, these are links between data centers or that are in different cities that use coherent modulation. These are generally very high data rate, 128-gigabaud data rates and the customer base that's building these as sort of a different customer base than the, let's say, the traditional data center customer base and we've started to see a ripple effect that the growing data center demand is now increasing the connectivity between data centers at higher rates. And so, we are involved in some nice programs that are as high as 1.2T for coherent modules, where we supply chips into those solutions. So that business is doing well. We're actually continuing to build backlog to support our metro long haul business. So, we think that business will continue to grow over the next few quarters.

That helps. Thank you. And maybe, help me understand whether I think there's a similar dynamic in the industrial part of your industrial & defense. I think in your prepared remarks, you said that performance was unremarkable in those industrial end markets. And I suspect there's an over inventory situation there as well, but I'm not sure. So maybe, you can clarify please.

Yes. I would say that we see that there's a few catalysts in the industrial sector right now for growth and that is, so I would say end demand is weak and then perhaps there's an overhang of inventory issues, but we see that more fundamentally a weak environment.

Thank you. And our next question coming from the line of Quinn Bolton with Needham & Company. Your line is now open.

Hey, guys. This is Neil Young on for Quinn Bolton. I know you touched on gross margin a little bit when discussing the Wolfspeed RF fab. But I guess looking forward, what are your gross margin expectations throughout the rest of the year? And if possible, could you walk us through the puts and takes? Thanks.

Yes, Neil. this is Jack Kober. So, as we've looked back over the past couple of quarters, we've been in the mid-57% gross margin range. And also, looking forward to our guide that puts us roughly in a similar spot at 57.5% as the midpoint of the guide. As we get out longer term, I think we'll have to see how things play out from an overall mix perspective. We've continued to have some lower utilization of our low fab, just where all of the costs are not being absorbed like they were a number of years ago. Some of that is driven by the low demand that Steve was just referencing with regard to the industrial end markets that we service. So, as we go out longer term, we're going have to see how it plays out. But in terms of the guide that we have going out through Q3, still in that mid-57% range is where we see things.

Okay, great. Thanks. And you did mention tariffs in your prepared remarks. I was wondering if you've seen any direct or indirect impact so far. And if not, I guess looking forward, which areas of business by product line or end market do you think would be more exposed and which would be more insulated? Thank you.

Thank you for the question. So, I would say that we've not seen any noticeable impact to date, regarding customer behavior, whether pull-ins, push-outs, cancellations, we've seen none of that. I'll just remind everybody that, over 95% of our business is direct with customers, and in some cases with partners, reseller partners. So, we have good line of sight of major programs. We're selling non-commodity products that are generally sole source. So, we have a lot of stickiness with our business. So, I would say that we'll continue to monitor the situation. Of course, we have a complex manufacturing and assembly manufacturing footprint. But I would say that this is something that the team is more than capable of managing. And in terms of breaking out country of origin by product line, we're not going to do that due to competitive reasons and other reasons, and the potential impact is always subject to change anyway. So, I would just reassure investors that our business is unique. It's, in many ways, very U.S. centric, about half our businesses here in the U.S., built and shipped into The U.S. And then the balance, other sort of half of our business, I think we're going to be able to manage quite well.

Thank you. And our next question coming from the line of Blayne Curtis with Jefferies. Your line is now open.

Hey, guys. Good morning and great results. I actually want to go back to -- on the Data Center market. I thought you said mid-40s and I just clarify that. I'm assuming that's fiscal year. And I just want to understand, I mean, I guess, if you take it straight literally, that would be a down September and I think you said something about lumpiness. I thought when we saw you at OFC, it seemed like you had that transition 800G and it was coming in at plan. So maybe, you can just elaborate on what that messaging was.

I think as we had this is Jack, Blaine. As we had talked about, high level, if you look year-over-year, and that's fiscal year 2025 for us, we'd probably be in the mid-40s. I think we can support growth as we talked about going into the third quarter. Fourth quarter, as Steve had mentioned, is still to be determined, but still the underlying demand is there to support growth even going into our fiscal fourth quarter.

Got you. Thanks, Jack. And then maybe, another one for you. I just want to ask on OpEx. I think it increased $5 million or $6 million in March. And I think the implied guide is probably something similar, maybe $4 million or $5 million. So, how do we think about OpEx for the year?

Yes. We've seen a step-up here in the operating expenses, as I had described in my prepared remarks with some continued investments. We've been carefully managing our operating expenses over the past number of years. So, with that step-up, we've made investments obviously in R&D type applications, but there's also been other things as we're growing to that $1 billion run rate that we hope to achieve in terms of investing in the business and things including IT infrastructure and IT security. So, there's other things that we're seeing. As we work our way through the remainder of the year and once we get beyond that, the Q3 time period, we would probably see a bit more of a leveling off of the operating expense increases from an absolute dollar's increase standpoint, going into Q4 and as we work our way through fiscal year 2026.

Thank you. And our next question coming from the line of Srini Pajjuri with Raymond James. Your line is now open.

Thank you. I just want to go back to the previous question on data center. The September commentary, I understand the visibility is not great in these businesses. but at the same time, are you seeing any sort of inventory at your customers? Is that what's giving you pause? Because on one hand, I see that the market is moving to 1.6T and you also talked about the potential opportunity on the LPO, LRO side. But I guess your commentary about September sounds a bit cautious. So, I'm just trying to understand what's giving you that a little bit of caution as we head into September.

Yes. thank you for the question. So, just to be clear, we're not guiding for the fourth quarter. So, we go out one quarter at a time and we're certainly very confident in the numbers that we're forecasting for Q3. So, I just want to make that point and we would always be very, very cautious about commenting on more than one quarter out and you shouldn't read into that, as a negative news, let's say, or a negative commentary or sentiment. It's just being cautious and especially cautious in our most volatile market as we talked about, which is the data center. In terms of the general trends, I would say that, what we talked about on the last call is also playing out as we had expected, which is that we were seeing a major customer of ours ramp down multiple 800-gig platforms and at the same time, we were ramping up other customers at 800-gig and the timing, and how those things come together has yet to play out. So, I would just highlight that. The second thing I would highlight just regarding 1.6T is there's really only one major company in the industry that is very focused on 1.6T. The rest of the industry is primarily focused on 800, 400 and even 100. And when we peel apart our revenue and our numbers as we look forward, we see continued growth in even some of the lower data rates including 100G platforms. So, I just want to highlight that. The other thing I would highlight is, we do not see an inventory issue in the Data Center segment. I would say it's the opposite. We are being expedited across multiple platforms, multiple data rates, multiple end customers. And so, it's really the opposite. Customers are -- they want their products, they see demand and there's a lot of pressure on MACOM and our operations team to do more faster, which is a good problem to have. So hopefully, that gives you comfort without guiding to Q4.

Yes. Thanks, Steve. That's very helpful. And then on the same topic, kind of mentioned that the LPO-LRO standards have been ratified. Just want to hear your thoughts on what you're hearing from your customers in terms of what sort of interest there is in the market and what sort of applications are customers looking to implement these solutions and in terms of speeds, are you seeing more interest in lower speed versus higher speed for these applications? And also, if you can talk about whether these applications are seeing interest from the so-called mega clusters or is it more for cloud workloads? I think that would be very helpful. Thank you.

Yes. I would say a few things. What's interesting is, first of all, most of it, the folks that are interested are at 100-gig per lane for 800G solutions, that's number one. The second comment I would make is not all ISPs are interested right now in LPO. Some are very interested and some are going to take a wait and see, and we see the full spectrum. We have, as an example, ISPs that they care about reliability and they don't care about power consumption or cost and others, it's all about power, latency and cost, and they're willing to lean into new technologies like LPO. So, I think we're in this mode, where people are very interested, they are looking at different use cases and it's still very early. So ultimately, ISPs are interested or not, I mean, that's proprietary information to MACOM. So, we're not going to discuss the engagements at that level. But I can say that we see the continuum of interest and I would highlight that not all ISPs are interested today. I think over time that will change as the use cases and scale are proven out, and then the more risk averse will perhaps adopt. In terms of the application, we see server to NIC or I should say, NIC to switch and generally very short reach, and that is the area that we will probably go into production first.

Thank you. And our next question coming from the line of Peter Peng with JPMorgan. Your line is now open.

Hey. thanks for taking my question. On the Data Center, you guys do have, like, several new products coming, like your photo detectors, your CW lasers, and your ACC solutions. Maybe, you can talk about, like, how to think about the revenue ramp there, and how material could it be in this in the second half of this year and more so in in the next fiscal year?

Sure. I mean, to highlight that within our Data Center segment, we have multiple product lines, multiple functions, multiple form factors and so to sort of call out two or three that may or may not be ramping is sort of understates the breadth of the product line. So, I just want to highlight that. I did comment in the remarks that our 200-gig photodetectors are ramping and those are primarily for 800G DR4 applications. And that I don't want to necessarily comment on the materiality of that. We also see opportunities and activity at 1.60T as well, just to be clear on the 200-gig PD. I would say that the overall performance of our NPI metrics for our data center products is best-in-class. We have a very high success rate of designing products, getting them to market and getting design wins that we had originally targeted. So, our team does a very strong job with execution in this area. And I'll highlight that today, supporting our data center business, we actually have eight different design centers collaborating on different projects to support this business. And so, a lot of moving parts, a lot of different end use cases, as I mentioned in my script, we are starting to take a very serious look at PCIe, as the networks and the data centers begin to disaggregate memory and storage, that creates opportunities for high-speed connectivity. And so, that would be another example of the SAM expanding, where we are going to try to insert ourselves directly into those opportunities.

Perfect. Thank you. And then, on just on the gross margin, I think in aggregate, your telecom and Industrial & Defense kept coming in a little better, and I would think that would maybe help some of the utilization at your low fab. Maybe, just remind us like what is running through your -- what kind of products are running through your low fab and maybe why even with the upside, it's more flattish gross margin?

Sure. And I think Jack touched on this a little bit that generally speaking, the utilization rates of our low fab have not changed over the past couple of quarters. Most of the products within the low fab are RF products. We have different categories. We have discrete diodes and there's about a half a dozen different product families within the diode product line. We also have MMICs that are gas or GaN running through the fab. Additionally, we are running indium phosphide lasers through the fab. So, it's a high-mix, medium-volume fab. I would say there generally is more exposure to defense and industrial related markets with the low fab, not entirely. but I would say that's the most exposure. And as we've been talking about over the past couple of quarters, our industrial business is down. And so, while our defense business is growing quite strongly, it's coming from other areas of our technology portfolio.

Thank you. Our next question coming from the line of Richard Shannon with Craig-Hallum Capital Group. Your line is now open.

Well, hi, guys. Thanks for taking my question. Maybe, a follow-up in the I&D segment here. You're clearly suggesting industrial is soft, which is not necessarily surprising. but it says the defense part here is doing very well. I'd love to get a sense of if there's any large programs that are driving this very strong growth we're seeing in this quarter. Does that convey over to following quarters here? And would it seem to suggest that the I&D segment kind of takes growth leadership, for MACOM as we get into fiscal '26?

Thank you for the question, Richard. Our core area in defense is centered around radar systems. Second to that would be EW and communication systems. And so, when we look at these platforms, we envision not just selling RF content, but also optical content and subsystem content. And so, you have a wide range of solutions and platforms that we're selling to these large programs. There is absolutely a refresh going on with radar systems across multiple platforms to address drone related threats. We are involved in both sides of that equation. We're involved on the next generation drones that have more sophisticated sensors, as well as technologies that want to knock the drone out of the sky. So, we would be looking at ways to support both of those applications. As we look at our business and our strategy, our strategy is to bring more technologies to bear on this market. And we've talked over the last couple of years about MACOM pivoting a lot of its analog mixed signal and optical technologies into the defense market, and that strategy has been playing out and proven to be very successful. In terms of our 2026 and the potential growth there, I think it's too early to say, other than I just highlight that our team has never been busier in terms of the amount of opportunities. When we acquired Wolfspeed's portfolio, it was a major booster shot of high-power technology to MACOM and we are taking full advantage of that in the market. So, we believe we are gaining market share in large radar systems, not only ground-based, but shipborne and airborne.

Very helpful details, Steve. Thanks for that. My second question is in data center. Really kind of looking at the newer products and how do we think of this over the next one years to two years. Obviously, you just started selling the PDs here at 200-gig, talked about CW lasers and LPO. How do we think about kind of the timing, I guess, more so on the CW lasers and LPO? But then if you look, say, one to two years out, which one of these newer areas within this bucket do you think can have the most impact?

Yes. I think that's a tricky question, because I would say our batting average on calling the future is not so good and we've had examples in the past, where we thought one product line would have a breakout year and it turns out it was another one. And so, I would say that we would rather talk about the successes of these new product lines retrospectively. And so, we're talking about the PD, because we have big orders and we're ramping production and as the other product lines come on, we'll certainly do the same there. With that said, I would just highlight, we are very interested in taking a position in the market on CW lasers. We have a unique technology with our edge faceted technology and we believe that the market demand for CW lasers is increasing, but we still have a lot of work to do. I think that the market wants a 75 milliwatt or 100-milliwatt part and we're working to make sure that we can feel the very competitive part. So, still a lot of work to do there. But of course, if we have success on lasers, it could be a meaningful number, but we don't want to count our chickens before they hatch.

Thank you. And I'm showing no further questions in the queue at this time. I will now turn the call back over to Mr. Steve Daly for any closing remarks.

Thank you. In closing, I would like to acknowledge and thank all of our employees for their continued dedication. Have a nice day.

This concludes today's conference call. Thank you for your participation and you may now disconnect.
