Welcome to MACOM's Fourth Fiscal Quarter 2023 Conference Call. This call is being recorded today, Thursday, November 09, 2023. 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, Livia. Good morning, and welcome to our call to discuss MACOM's fourth financial quarter and financial year 2023 financial results. I would like to remind everyone that our discussion today will contain 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 more detailed discussions of the risks and uncertainties that could result in those differences, we refer you to MACOM's filings with the SEC. Management's 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 provide a more in-depth review of our fourth quarter and full year results for fiscal 2023. When Jack is finished, I will provide revenue and earnings guidance for the first fiscal quarter of 2024, and then we will be happy to take some questions. Revenue for Q4 was $150.4 million, a slight increase over the prior quarter. Adjusted EPS was $0.56 per diluted share, and operating cash flow was approximately $50 million. For the full fiscal year ending September 29, 2023, revenue was $648 million, and adjusted EPS was $2.70 per diluted share. Fiscal 2023 revenue and EPS were both down 4% year over year. We completed two small but strategic acquisitions in fiscal '23, which combined contributed approximately 2% to our total fiscal year '23 revenue. During the fiscal year, we eliminated all of our remaining short-term debt and funded these acquisitions using cash recently generated by the business. We ended the fiscal year with approximately $515 million in cash and cash equivalents. In Q4, our book-to-bill ratio was 1.1 to 1. In our turns business, our orders booked and shipped within the quarter was approximately 16% of total revenue. These are positive trends, and notably, Q4 bookings improved across all three of our end markets. Improvements were led by pockets of strength at certain defense and Data Center customers. Our total company backlog increased slightly quarter-over-quarter, and it remains at a healthy level. We are starting the new fiscal year in a strong position. While we are pleased with the recent improvement in total bookings, in certain markets, orders remained weak in Q4. Demand continues to be weak in telecom and to a lesser degree in certain parts of the industrial markets, and we remain negative on the near-term outlook for these markets. However, more positively, we see growing demand in Data Center, aerospace and defense, as well as in satellite communication markets. Fiscal Q4 revenue by end market was as expected, with industrial and defense at $79.2 million, Data Center at $40.5 million, and telecom at $30.6 million. I&D was down 5% sequentially, Data Center was up 52% sequentially, and telecom was down 20% sequentially. Notably, our top 10 end customers represented approximately 30% of our total revenue in fiscal 2023, and no one customer was more than 10% of our total revenue. We maintain a highly diversified customer base consisting of thousands of customers. Industrial and defense was a strong market for us during fiscal 2023, and revenues achieved a historic level. Fiscal 2023 represented our third consecutive year of growth within the I&D market, with 8% year-over-year growth. In fact, the I&D market with 8% year-over-year growth. In fact, over the last three years, our I&D revenues achieved an 18% compounded annual growth rate. We believe our growth initiatives for this market are on track. Core to our strategy is expanding our serviceable addressable market or SAM within the I&D market by launching compelling new products. As a reminder, examples of new growth initiatives, which we've discussed in prior quarterly calls, include our new 0.14 GaN on silicon carbide process, kilovolt capacitors or KV caps, and BAW filters. These product lines are still in the early stages of their growth and product life cycles. One important area of the I&D market we are supporting is the RF over fiber segment. In these applications, customers convert RF or microwave signals into light by directly modulating a linear laser. This resulting signal can be transmitted over fiber with minimal signal degradation or loss versus traditional coax cable. Fiber provides a lower weight and more secure transmission compared to coax. RF over fiber is ideal for demanding applications like SATCOM ground station networks, distributed antenna systems, and many defense applications like secure communications, critical GPS systems, and radar systems, all of which require high reliability and long life cycles while operating in harsh environments. MACOM's strength in microwave and optical design, laser and detector technologies, and ruggedized packaging and subsystem manufacturing capabilities position us for growth in this segment of the defense market. We are seeing a growing number of long-term program opportunities today. Another area of focus for MACOM in industrial and defense is further penetrating the test and measurement market. A notable recent new product introduction for this market segment is our optical clock recovery or OCR solutions. Here our high-performance connectivity team is leveraging our PHY technology, our high-speed optical receivers, and high-performance analog design expertise. MACOM's OCRs can be used in our customers' production test environment to validate their performance of their short reach 400G and 800G optical transceiver products. Our telecom end-market revenues continues to be weak. In fiscal year 2023, telecom was down 24% year-on-year. Weakness in this market is broad-based, spanning most of our larger subsegments including 5G, Metro long haul, cable infrastructure, and passive optical networks. That said, we believe the secular growth drivers for telecom remain intact. Global telecom infrastructure needs to expand capacity to carry higher data rates and more bandwidth all while having lower latency. As an example, recently a US carrier completed field trials in New York State which demonstrated 1.2 terabits per second of data over a single wavelength in a long-haul metro application as part of an ongoing fiber optic upgrade. MACOM supported this trial with our products. One segment in the telecom market which we believe is growing is broadband satellite communications or SATCOM and many of these ground and satellite systems operate at microwave or millimeter-wave frequencies, which plays to our expertise. Telecom remains an attractive and diverse market and we see numerous opportunities to expand our position in this market. Our Data Center end market revenues grew sequentially in Q4. In addition, for the full fiscal year 2023, Data Center revenues grew by 6% year-over-year, growth that was primarily driven by high data rate short reach applications. The Data Center market continues to provide growth opportunities for MACOM and we expect new product introductions will be the primary growth driver for us in this market. We are focused on designing and producing industry-leading cross-point switches, high-speed TIAs, and laser drivers for a wide range of applications. Our strategy is to be the first to market when data rates jump to higher speeds. As an example, we recently announced and demonstrated an industry-leading 200G per lane transimpedance amplifier or TIA for short reach applications and a 200G per lane linear equalizer for use in active copper cables. Both products will support 1.6T deployments. Data Center architectures continue to evolve. We believe many of today's deployments require significantly more short-reach optical and/or copper cable to make connections. Our high-performance connectivity team offers an industry-leading portfolio of products at 50 G, 100 G, and 200 G per channel to support these requirements. In some applications, our solutions enable lower cost, lower latency, and lower power consumption versus traditional solutions. Additionally, our linear equalizer products enable copper interconnects to be extended in reach and into higher-speed applications. Previously, a market segment addressed with more expensive active optical cables, or AOCs, and pluggable transceivers. Our solutions have been tested with the latest generation of switch ASICs available on the market today, and our customers are pleased with the performance. Given we are at the start of a new fiscal year, I would like to review our long-term strategy, briefly recap some of last year's accomplishments, and review our priorities for fiscal 2024. Simply put, our strategy is to focus on the highest power, highest frequency, and highest data rate applications in our three core markets. We align our R&D and product development resources around these themes, and then, using our annual strategic planning process, establish near and long-term goals to strengthen our portfolio's competitiveness and to position the company for future success. Our goal is to have our technical teams work closely with our customers to provide unique options for them to consider. By leveraging a wide breadth of unique technologies with world-class manufacturing strengths, we believe we can attract many customers and gain additional market share. We believe customers will seek out suppliers who can, over the long term, become strategic partners. During last year's Q4 earnings call, we outlined our priorities for fiscal '23. Our team made meaningful progress against those stated priorities. As a reminder, a central theme we communicated then was to capture market share in '23. We believe we've been gaining market share by increasing our new product offerings, expanding our technology base, and strengthening our presence in certain geographic regions. As I've mentioned, a key component of our strategy involves building a portfolio of compelling semiconductor processes to support high-frequency and high-power applications. The opening of our MACOM European Semiconductor Center expanded our manufacturing capacity, added epitaxial growth expertise, bolstered our European presence, and strengthened our design teams. This acquisition supports our strategic goal to establish a leadership position in very high-frequency semiconductor process technologies and products. While this was a relatively small acquisition, we believe it is strategic and it brings us tremendous growth potential. We are confident our strategy will enable higher-than-average return on invested capital and therefore support our goals of establishing exemplary profitability and cash flow. In support of diversifying our revenues geographically, we are expanding our sales efforts across Europe. During Q4, we attended the European Microwave Week in Berlin, where we hosted a number of live demonstrations at our booth, which featured our latest products and technologies. In addition, we are pleased that the European Space Agency, or ESA, recently completed a site visit at our France facility. We intend to build new relationships with major organizations and customers across Europe with the goal of driving long-term revenue growth, diversifying our customer base and adding further stability to our overall business. During the year, we introduced 170 standard products, an increase of 15% compared to last year. We also had great success with our custom IC development activities and we supported a wide range of customer-funded projects. We recognized that continued investments in expanding our design engineering, new product prototyping, and engineering test capabilities will ensure we move quickly and rapidly bring products to market and ultimately gain market share. As we look ahead to fiscal year 2024, we anticipate that the rate of new product introductions will further accelerate. In fact, we believe it is possible to launch 50% more products in FY'24 compared to FY'23. As we focus on fiscal year '24, our priorities include extending our leadership in RF and microwave applications, taking market share on GaAs and GaN mimics, continuing to gain traction with our high-speed analog solutions for short-reach data center applications, completing the integration activities of our recent and pending acquisitions, driving additional growth of our RF power, analog, and lightweight product areas, building out and growing our module and subsystems business in select high-performance markets, ensuring management challenges, develops and rewards employees, and supports their needs to ensure they have a long and enriching career at MACOM and last, managing the business and strategy to enable us to achieve record earnings for the future. In summary, MACOM has a wide range of products in production today. Many of these products have long life cycles and can produce revenues for years after they've been introduced. We view these business attributes as an inherent strength of our business model. And last, I'll note that MACOM and Wolfspeed have been working collaboratively on a carve out of their RF business over the past few months. I would like to thank the integration planning teams from both companies for their great work. Our integration planning efforts include aligning the team we are hiring, their organizations, and the ERP and other data systems with MACOM's infrastructure, so we are fully operational and independent at closing. I have no doubt this transaction will be a win for MACOM. Jack will now provide a more detailed review of our financial results.

Thank you, Steve, and good morning, everyone. Before getting into the details of our quarterly results, I would like to summarize a few items associated with our fiscal year 2023 financials. As Steve noted, fiscal 2023 was down approximately 4% from a top and bottom line perspective. Despite this, we've been able to maintain adjusted gross margins in excess of 60%, with full-year fiscal 2023 adjusted gross margin of 61.3%. During fiscal 2023, we have maintained solid and consistent cash flow generation, which has allowed us to close and fund two strategic acquisitions with available cash and also pay off the remaining $121 million balance of our term loan that was scheduled to mature in May 2024. Now, on to our Q4 quarterly results, as well as some additional commentary on our full fiscal year 2023 and outlook on fiscal year 2024. Revenue for the fiscal fourth quarter was $150.4 million, up 1.2% sequentially, based on growth in our data center market. On a geographic basis, revenue from U.S. domestic customers represented approximately 46% of our fiscal Q4 results, down from 49% in fiscal Q3. We've been working to geographically diversify our business and are pleased to have a healthy mix of U.S. and international-based revenue opportunities. On a fiscal year '23 annual basis, revenue from U.S. domestic customers represented 48%, up slightly from 47% in the prior year. A notable trend is our fiscal year '23 revenue from the China market decreased, while revenue to our European-based customers grew compared to the prior year. Adjusted gross profit for fiscal Q4 was $90.3 million, or 60.1% of revenue, essentially flat from the third quarter. Total adjusted operating expense for our fourth fiscal quarter was $53.1 million, consisting of research and development expense of $33.8 million and selling, general and administrative expense of $19.3 million. The modest sequential increase in adjusted operating expense was primarily driven by incremental costs from our recent acquisitions, partially offset by lower spending across the remainder of the MACOM-based business. Depreciation expense for fiscal Q4 was $6.3 million and $24 million for fiscal year 2023, essentially flat on an annual basis. MACOM's asset base includes a variety of production and research and development equipment that we are continuously working to optimize, which has helped to keep our capital expenditures and the associated depreciation expense relatively stable over the years. Adjusted operating income in fiscal Q4 was $37.2 million, up slightly from $37 million in fiscal Q3. For fiscal year 2023, adjusted operating income was $189.6 million compared to $211 million for fiscal 2022, resulting in a 200 basis point reduction in adjusted operating margin compared to fiscal 2022. For fiscal year 2024, our team plans to further integrate and optimize our acquisitions, further executing on incremental synergies and cost savings while running the entire business with a continuous improvement mindset and working to increase our operating margin over the course of the year. For fiscal Q4, we had adjusted net interest income of $4.2 million compared to net interest income of approximately $2.8 million in fiscal Q3. Fiscal year 2023, adjusted net interest income was $10 million compared to an expense of $2.6 million in 2022. The increase in fiscal year 2023 adjusted net interest income was driven primarily by higher yields on our short-term investment balances. Our adjusted income tax rate in fiscal Q4 was 3% and resulted in an expense of approximately $1.2 million. Our net cash tax payments were approximately $100,000 for the fourth quarter and $2.9 million for fiscal year 2023. We expect our adjusted income tax rate to remain at 3% for fiscal year 2024. As of September 29, 2023, our deferred tax asset balance was $218 million as compared to $237 million at the end of fiscal 2022. We anticipate further utilizing our deferred tax asset balance through fiscal 2024 and into fiscal 2025, helping to keep our cash tax payments relatively low over these periods. Fiscal Q4 adjusted net income increased to $40.1 million compared to $38.5 million in fiscal Q3. Adjusted earnings per fully diluted share was $0.56, utilizing a share count of 71.8 million shares compared to $0.54 of adjusted earnings per share in fiscal Q3. Now moving on to operational balance sheet and cash flow items; our Q4 accounts receivable balance was $91.3 million down from $105.9 million in fiscal Q3 due to improved shipment linearity and strong collection activity during the quarter. As a result, day sales outstanding were 55 days compared to 65 days in the prior quarter. Inventories were $136.3 million at quarter end, down sequentially from $139 million. Inventory turns were 1.8 times up sequentially in Q4 from 1.7 times in the prior quarter. We recognize that our inventory balance is relatively high and associated turns continue to be relatively low. However, the quality and mix of our inventory is strong and continues to support our strategic backlog. Fiscal Q4 cash flow from operations was approximately $50.4 million, up $4.5 million sequentially. Capital expenditures totaled $5.8 million in fiscal Q4. Fiscal 2023 annual CapEx of $24.7 million decreased slightly from $26.5 million in fiscal 2022. Our operations and facilities teams are very disciplined and do a great job managing our capital expenditure budget. As we move into fiscal year 2024, we expect our capital expenditures to be in the range of $30 million to $35 million for the full year. Next, moving on to other balance sheet items. Cash, cash equivalents and short-term investments for the fourth fiscal quarter were $514.5 million, down $73.1 million sequentially, driven by the $121 million paydown of the remaining term loan. I am pleased to note that as of the end of our fiscal year 2023, we were in a net positive cash position of approximately $25 million after closing two acquisitions and paying off the term loan. Our balance sheet and cash generation remain sound and we continue to exercise leverage over our operations and discretionary spending to support MACOM's target margins through ongoing cyclical pressure. In summary, fiscal 2023 was a solid year for MACOM, and I am proud of our team's performance and accomplishments and believe the diverse, resilient portfolio we have built will support future growth of the business. In addition, we are working with Wolfspeed to close our previously announced acquisition of their radio frequency business before the end of December. As we have previously discussed, we expect the RF business to be immediately accretive to MACOM's non-GAAP earnings, and this acquisition is not expected to change MACOM's long-term adjusted gross margin goals of being above 60%. We also expect the business to generate enough cash to provide a 100% return of the purchase price in around three years. We believe that based on the structure of the transaction, actions to be taken prior to closing, as well as post-closing synergies, we will be able to improve the current gross margins of the Wolfspeed's RF business. That said, given MACOM's and Wolfspeed's RF business's current revenue levels, we anticipate modest gross margin pressure immediately following closing, as certain post-closing synergies will take time to realize. We believe the acquisitions announced during fiscal 2023 will be strategic for MACOM's capacity, capability, and customer base for fiscal year 2024 and beyond. I will now turn the conversation back over to Steve.

Thank you, Jack. MACOM expects revenue in fiscal Q1 ending December 29, 2023, to be in the range of $149 million to $153 million. Adjusted gross margin is expected to be in the range of 59% to 61%, and adjusted earnings per share is expected to be between $0.55 and $0.59 based on 72.2 million fully diluted shares. In fiscal Q1, we expect industrial and defense and telecom revenues will be down or flat quarter-over-quarter, and data center revenues will be up 10% quarter-over-quarter. Our guidance does not include any contributions from the pending acquisition of Wolfspeed's RF business, which we expect to close prior to the end of December. We maintain a long-term perspective on executing our strategy, and we are confident that we can continue to improve our financials and take market share in the months and years ahead. Our level of engagement with leading customers is improving, and we have a robust opportunity pipeline. In short, we believe MACOM will be bigger, stronger, and more profitable in fiscal 2024. I would now like to ask the operator to take any questions.

Our first question comes from Tore Svanberg with Stifel. Your line is open.

Yes, thank you. My first question is on the industrial and defense business, especially in the near term, Steve. You said there's some puts and takes there, especially in the industrial. Perhaps some areas are still doing okay, but others are perhaps weak. So, could you just elaborate on which of the segments are holding up versus those that may potentially be seeing some weakness?

Sure. I would say, in general, across the board, our defense business is strong. So, that segment is doing quite well, and it's our expectation that that strength will continue as we move into 2024. On the industrial side, I would say that there are probably three areas that I would call out as being weak. One would be the medical segment, which we support primarily with MRI systems and things like that. The second would be general sensors. These could be automotive traffic sensors or industrial sensors and then the third would be our support of the general RF and microwave testing measurement segment, where we see our major customer's demand is quite weak.

Yeah, that's very helpful and as my follow-up for Jack, obviously, we're not including any financials from the Wolfspeed acquisition this quarter, although obviously it sounds like it's going to close before the end of the quarter, but you mentioned some gross margin pressure initially. Could you maybe expand on the magnitude of that? Are we talking about maybe a couple hundred basis points, or should we start to think about potential more dilution than that?

Thanks, Tori. And I think you were referring to the Wolfspeed RF pending acquisition.

Sorry, I apologize.

That's all right. I just wanted to make sure we were aligned. There may be some slight dip that we may see as we work through the closing, but I wouldn't expect that to be that significant and to last for a longer duration. Our gross margin story remains intact, and expectations are to be back up into the 60% range. Even as we work our way through the closing and shortly after that time period, there's a possibility that we could remain above the 60%. There's just a lot going on that we need to digest as we work our way through the closing period and integration time period.

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

Hey, good morning. Thanks for taking my questions, and congrats on navigating this challenging environment. I guess first maybe on the data center business, do you expect to see any seasonality there, and how long do you think this continuation of demand can be sustained? Is it throughout 2024? Do you see a period in which we might see maybe a step back in the data center, maybe slow a bit for you?

Thank you for the question, David. So the data center, which is today our smallest segment, is probably our most volatile segment, and I would probably characterize the revenue as dependent on ramps, ramping up and ramping down, as opposed to seasonality, sort of calendar-based seasonality. Today what we see is, certainly we saw this quarter, very strong growth, primarily from short-reach applications, and we believe that growth will continue as we're guiding 10% growth this quarter off of tremendous growth in Q4. As we look into 2024 and even into our fiscal 2025, we think the strength will remain, but there will definitely be a shift from what today is, let's say, 400 gig and 800 gig demand to more 1.6 terabit-based demand, and we feel we're on that cutting edge. So we do believe there'll be volatility over the next 24 months as things turn on and turn off, but generally speaking, we think we're well-positioned and we'll have a good '24, and we'll see how things shake out in our fiscal '25.

Thanks for the color. And then just, if I recall, most of the Wolfspeed acquisition, most of the products are expected to kind of flow through that industrial side. How do you think about this segment, just kind of given the macro weakness you're seeing and we've been hearing about in the industrial side? Anything change there in terms of your short-term thinking and synergies or other fundamentals?

Well, yes, and I think we have a lot of thoughts about the Wolfspeed business, and I really don't want to comment on sort of how they characterize their business today. We'll certainly do that on our next earnings call when we talk very specifically about perhaps some of the changes we're going to be making and some of the focus that we'll make, but I would highlight that it's a very strategic acquisition for us. They have compelling technology and growing markets, whether it's A&E, industrial, or telecom. They have a tremendous built-in customer base today that really spans our industry, and they have a real strong portfolio of high-voltage, lower-frequency process technology that today MACOM does not have. So we're very excited about it. We've been working with the management team, as Jack mentioned. We've gone through and done a lot of work to make sure that the resources that we bring over support our growth as well as financial targets, and we think we've done a reasonable job there trying to sort of pick the team that will ensure success in the future. So very excited about that, but I really can't comment on exactly their business today, and we'll talk more about that after the close.

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

Hey, guys. I'll echo my congratulations on steady execution in a challenging market. Steve, I wanted to kind of follow up on a data center question. You guys have seen some pretty strong growth in September and forecast to continue to grow in December, admittedly off a low base, but it sounds like the transition to 400 gig, 800 gig, and in the future 1.6 gig modules is driving a lot of that growth. And I guess I'm wondering on the PMD side of the business, are you benefiting from a move back to more discrete PMDs that are silicon, germanium or compound semiconductor-based rather than CMOS-based as we move to those higher speeds? Do you see that trend to higher speeds benefiting your PMD portfolio?

Right. So I would say that a few things. Certainly, the trend to the higher data rates is an area where we want to position ourselves. We use a wide range of process technologies, not just silicon-based, but also three, five based. And so we'll make sure we bring the right technology to bear on the application. So I don't necessarily want to comment any further in terms of what flavors or what process of technology we're using for certain applications. That's competitive information, let's say. The other thing I'll highlight is we have, while we are seeing very strong growth on the higher data rates, we are seeing a lot of weakness at the lower data rates, including the NRZ, both at 25G and 100G, whether it be AOCs or pluggable transceivers for the data center. So our data center business is shifting. It's a bit of a mixed bag, but the good news is we have some real bleeding-edge technology for those PMDs that you mentioned, specifically the TIAs and the drivers, the equalizers and we've really built out a really nice portfolio there. And I have to highlight that within each one of these product categories, there are multiple products. We find that our customers are designing their systems in a very unique way. So oftentimes, we target applications and target footprints that are unique to those sockets and given the speeds and the data rates, we feel like that's necessary. So this is not a commodity product. It's not something that's easily removed from a platform, let's say and so for that reason, it has very attractive business attributes.

And then my follow-up question on the data center business, I wanted to ask about the linear pluggable or just linear drive optics. It kind of feels like at recent trade shows, the ECOC show and Open Compute Summit, everybody in the industry seems to be acknowledging that there's been progress made on linear optics and just kind of wondering if you could give us an update as to what you're seeing on the linear side and when you may start to see linear drive or linear optics starting to move to production applications. Thanks.

Thanks, Quinn. So certainly in our fiscal '24 is when you're going to really start to see linear drive kick in. And I would just add to that that linear drive is not for all applications. It's really for applications where you have either 100G or 200G per lane. So an 8x100 or an 8x200 is sort of the optimal case, and then that being a short-reach application. So some of the other applications like 8x50G, those type applications are going to continue to use DSPs and gearboxes, and that's really not an area of the market we're focused on. So I would just highlight that linear drive is not for all applications. It's not going to eliminate the necessity of DSPs within the data center. I think it's applicable in certain applications, and those are the applications that we're focused on.

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

Yes, thank you, gentlemen. Two questions, if I may, as well. I guess sticking to the Datacom theme, could you remind us which portion of your products are at 25 gig per lane and below? I ask because I'm hoping you can juxtapose the demand trends you're seeing across Hyperscale versus on-prem and enterprise campus applications.

So 25G or below would be products like clock and data recovery type products. It could be what we call combo chips, which could be a CDR and driver or a CDR and TIA. I would say that's the bulk of the type of product we sell into that market. Then sort of a second degree to that would be some of our lightweight products, including some of our lasers.

Okay, thanks for that, Steve. I guess pivoting to telecom, then, how should we think about the linearity of your telecom segment outlook in fiscal '24 or over the next couple quarters? I ask because several of your end customers suggest a mixed recovery but noted an inventory overhang for DWDM transceivers that may extend in mid-2024. So just curious to hear your thoughts on that segment. Thank you.

Yeah, so in this case, I think as you're defining telecom, you're focused on the sort of optical segment or the long haul. So in this case, in our vernacular, we call that a metro long-haul business. We do think that there will be pockets of strength in 2024 with our metro long-haul business. We see that some of those networks are being upgraded and also, as I mentioned in my script, we're participating in some of those transitions. I'll just highlight that these newer platforms are at 130 gigabaud, so they're extremely high frequency. The equipment is extremely expensive and that's an area where we want to position ourselves.

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

Thank you. Good morning, guys. A couple of questions. Steve, first, a little bit longer term question. You talked about market share gains contributing to fiscal '23 growth. Could you maybe elaborate on that? I guess subsegments end markets, you are seeing market share opportunities. I guess, where were the market share opportunities last fiscal year and how should we think about going forward what sort of opportunities do you see and what sort of, I guess, top line contribution you expect from share gains?

Sure. So, the first thing I would just highlight is that we have a very diverse business and we don't typically see a significant portion of revenue on any one product. So, when we talk about gaining market share, it's a lot of small and medium-sized wins at a lot of different customers. So, I'll just highlight that right up front. Certainly, we are gaining market share in industrial and defense, 18% CAGR over the past three years. That is due to the company's renewed focus on the market primarily. It's based on doing more custom development work, doing modules and subsystems for certain applications and so we are really very focused on that market. Today, that market is about 50% of our total business, at least it was in fiscal '23, 49%. And we think we have leading technology that will be of great interest to the major OEMs across this space. The second thing I'd highlight is we're definitely gaining market share in satellite communications, both in ground stations as well as on the satellite themselves with our various components. So, that's an area where we're definitely focused. We think this subsegment of the market will grow for us in fiscal '24 and related to that is something I mentioned in the script, which is RF over fiber, which is a very attractive application within not only commercial communication systems, but also defense applications and so, those are just three general areas that we're focused on, but remember, it's all about the new products and so to the extent we can launch more and more products every year, that will be the driver for our growth. And this past year, we did 15% more new products than the prior year and I mentioned in my script, our goal for fiscal '24 is to do 50% more new products and certainly, that takes into account the closing of the Wolfspeed team in December and then adding their contributions to our metrics. So, we are a product-driven growth company.

Got it. Thanks for that answer. And, Jack, on the book to bill, it's good to see it's, I guess it came in at 1.1 and just trying to get some color on where you're seeing the most improvement. Is this being driven by any particular subsegment? Or I see that data center you're guiding for growth, but if you could just give us some color on what's driving this improvement because the other two segments seem to be just checking along at the bottom, if anything, maybe some declines in industrial. So just wondering what's driving the improvement in book to bill.

Yes. And with regard to the book to bill, we have challenges, as Steve had mentioned in some of his prepared remarks, but if you look at some of the strength that we had seen here in the current quarter, much of that was around defense as well as data center bookings that had come in, and some of these are longer-term type delivery arrangements. So, they have longer lead time. So, you'll see some of that benefit us as we work our way through fiscal year '24.

Thank you. And our next question, coming from the line of Harlan Sur with J.P. Morgan. Your line is open.

Good morning. Thanks for taking my question. In telecom, it just seems that all aspects of wired and wireless infrastructure spending continues to be at low levels and obviously making it, I think, a little bit difficult for you guys to clear some of the excess inventories. But it does seem like quarter-over-quarter declines are shrinking. So, does it feel like the telco business is at a bottom after three to four quarters of other shipping consumption? Have things like orders started to sort of flatten out here in telco?

So, unfortunately, I don't know the answer to that question, Harlan, and you're correct that the telecom, our telecom segment has come down significantly. In fact, I think the performance we had in Q4 was, I think, at a three-year or four-year low. So just a few quarters ago, we were in the low $60 million run rate and we had been at that run rate for four quarters. So we really can't say with a lot of confidence where that's going in the broader sense. Year-over-year, down 24%, when we look out into our fiscal '24, we think that the data center will continue to be a strong market for us. We think the defense market will be a strong market for us, and we are the most worried about the telecom market. We think that certainly it's weak now, and when it turns and how it turns and who turns has yet to play out.

Yeah, I appreciate that and then on the data center segment, in addition to the strong demand pull for AI, which is obviously driving a lot of strong demand for 100 gig per channel solutions from you guys, there's been one large cloud and hyperscaler that up until this point in time has not started their broader data center footprint upgrade to 400 gig, which is more like 50 gig per channel. Is that US player finally starting to deploy 400 gig? Or is still most of the data center strength for you guys still around AI and maybe some incremental networking capacity build outs?

Yeah, so without talking customer specific, I would say that the strength that we're seeing we saw in our fiscal '23, and we think we'll continue to see will be at the higher data rates. So 200, 400, and 800 short-reach multi-channel devices that can support those data rates, and then we have different levels of penetration at different accounts, and we're by no means omnipresent in the industry. We're a small player, but we have solid relationships, not only with some of the ASIC manufacturers, but also the merchant DSP manufacturers, we want to support them. If they're offering a DSP, we want to make sure that we have our drivers and TIAs designed in as reference components if possible. So that's where we're positioning ourselves. That's our focus. And then again, I'll just highlight that we've done a lot of work over the past three to four years, developing a laser portfolio that would be competitive, and we have a variety of lasers in low-rate production right now. It's been a bit disappointing in the past 12 months in terms of getting sort of a breakout for that product area, but we have some great technology there, including CW lasers, which can support silicon photonics and laser arrays, which can support next-generation systems.

Thank you. And our next question coming from the line of Mark Lipacis with Jefferies. Your line is open.

Hi, thank you for taking my question. I have a couple of inquiries. I wanted to ask about the 50% increase you mentioned. You indicated that Wolfspeed contributes to this increase, which is why it's higher. Should we consider a normal productivity improvement of around 15% organically, with the remainder coming from Wolfspeed? I'm curious if you're seeing an acceleration despite what seems to be a relatively flat or slightly increasing R&D expense base.

Yeah, so I would say there's sort of two pieces there. One, we will have a full year contribution from our European Semiconductor Center. So there's a segment of products or a grouping of products that will come to market in 2024. So that was not there in '23 and then, of course, there'll be a Wolfspeed contribution, and then there'll be some modest growth from our existing base MACOM. I think that's the way you should really look at it. I'll just add that a lot of the work that our linear module systems group does, we don't really include those in the product count. Most of their work is custom development and not made public.

Got you. Okay, that's helpful and then, if you look at your revenues here, like peak to trough, assuming things don't go down from here, it looks like your peak to trough revenues are like down 18%. Can you share with us your view as to what extent is that decline, an inventory correction versus just a drop off of end market consumption of your products? Thank you.

Thanks for the question. So I think certainly inventory is an element of it. There's also end demand and you see major carriers throttling back some of their spending. So there's certainly shifts within the end-user community, let's say, in certain segments of the telecom specifically. I think generally speaking, industrial and defense budgets are going up and will continue to go up. So that will be a secular benefit to our business. I think we're in a good spot in the data center for the next few years, and certainly on telecom, there's broad-base weakness due to a variety of reasons, some of which you've highlighted. We are not good at predicting the future, and we would definitely get it wrong. So we're aware of the situation where as a result of that, we're being very conservative with our financials. We're focused on generating cash. As Jack highlighted, we have been very reserved on our capital spending. When we look at making investments, we want to make sure we get good returns, whether that is investments internally or looking at targets and acquisitions. So this is the time when you want to be sort of conservative and generate cash, and that's our posture as a company and with that, if we can continue to grow our portfolio and strengthen the portfolio, I think we will do just fine.

Thank you. And our next question coming from the line of Robert Aguanno with Piper Sandler. Your line is open.

Hey, guys. Thank you for taking the question. This is Robert on for Harsh Kumar here. You guys talked about a little bit on China customers and revenue decreasing and shifting over to Europe. Can you shed some more light on how you're thinking about that geography and whether or not a bounce back or any sort of recovery matters in your forecast going forward? So any updates on that would be nice. Thank you.

Thanks for the question. So we are definitely forecasting conservatively when it comes to growth within the China region. We today have facilities in four different cities. We have about 85 employees to 90 employees there that are focused on growing our telecom business, our data center business. There's still a significant amount of hardware that's supporting global networks that's manufactured, designed, and manufactured in China. So we will continue to have a strong presence and grow our presence to make sure that we're gaining market share in that area. That said, we are definitely investing in other areas to strengthen up our overall global footprint, and so we recognized a few years ago that we needed to strengthen our position within Europe. That was one of the drivers for our acquisition and to open up a small fab and we now call that MACOM European Semiconductor Center and we want to build off of that. So in our minds, having a balanced portfolio of products, customers, and geographic revenue is the goal, but to the extent that China continues to be a major player in the markets we're in, we will continue to support them.

Thank you, there. And just on the cost side, as well as my follow-up, how should we be thinking about OpEx contribution as maybe revenues come back to more normalized levels following this inventory correction? I guess we're in and around the 30% margin before this. Any color on recovery there would be helpful as well.

Sure, maybe I'll say just a comment and then pass it to Jack for a more complete answer. I would just highlight that the team here at MACOM did a great job managing our total OpEx, and if you compare our total OpEx from fiscal year '22 to fiscal year '23, it's almost flat for total OpEx and so I think that's a credit to the work that the finance organization, our operations, R&D, everybody has really stepped up to try to manage overall expenses, and we will continue to carry this footing. Jack, do you want to add to that?

Yeah, that's helpful, Steve, and we do take a very disciplined approach to our operating expenses. And a lot of those operating expenses are within our research and development area, and as Steve had mentioned in his earlier response, making sure we're getting returns from our investments in those R&D OpEx numbers that we're spending is a critical area of focus for us, but along the way, we continue to make some structural type changes to our overall organization to continue to optimize it, and that's resulting in the stability we've seen in our operating expenses. And also with fiscal year '23, we had two new acquisitions come online, and we were able to absorb some of the additional operating expenses that came through those businesses by being disciplined with our base business. So I think there's still some leverage that we have. Obviously, as the top line grows, we will be adding some operating expenses. But I think we'll be very disciplined, as we were going back to fiscal years '20 and '21 and into '22 when we were growing the top line, and we were growing the operating expenses at a much lower rate than our revenue growth. So more of the same as we continue going into fiscal year '24.

Thank you. And our next question coming from the line of Vivek Arya with Bank of America. Your line is open.

Hi, this is Lauren Guy on for Vivek. Thanks so much for taking my question. So I'll just start with noting that inventory dollars seem to come down sequentially in the quarter. Could you just speak a little bit on how you're managing inventory and utilization during the downturn? And if you can give any comments segment-specific on how inventory is looking, that'd be great. Thank you.

Yeah, no problem, Laurie. With regard to inventory, we were pleased with some of the reduction that we had seen here in the current quarter. Things continue to be challenged. We are careful in terms of where we invest our inventory dollars as well. We had noted this a couple of quarters back where we did see a bit of an uptick in our inventory, and some of that was to support some of the orders and backlog that we had coming through. So it's a careful balance as we work our way through the cycles here in terms of maintaining the appropriate levels of inventory to support our customer needs, but we've got a number of different metrics that we look to across the business that we're working to try and manage, and I'll also add that we did have the two acquisitions that had come to us over the past fiscal year. So that was a bit additive to our inventory balances as well, and we're working through some of the integration with those businesses as well, and hopefully, we'll see further refinement and improvement in some of the inventory metrics as we go forward. But we are keeping a constant eye on the dynamics that we have across the business. So it's something that we pay close attention to.

Okay, great. Thank you. And for my follow-up, just wondering how are you thinking about recent industry consolidation between Lamentum and Cloud Light and optical transceivers? How does that kind of impact your component-first strategy?

I don't think it changes our overall strategy.

Thank you. And our next question coming from the line of Matt Ramsay with TD Cowen. Your line is open.

Hey, guys, this is Sean O'Loughlin for Matt. Just two quick ones from me. First off, I was wondering if you could talk about the long-term model a little bit more. I know that you guys at one point had this billion-dollar revenue target, and that got pushed out a little bit, but I think it also came with maybe double-digit growth rate expectation. Obviously, a lot has changed since then, but we're just wondering how you're thinking about it from here.

Thanks for the question, Sean. Achieving a billion dollars in revenue is a matter of when, not if. Initially, we aimed for fiscal '25, which was set about 18 months to two years ago. However, we've faced several industry challenges that have delayed our progress. Over recent quarters, we've reassessed that target due to our declining year-over-year growth rate, which is understandable. Currently, we have an annual run rate of around $150 million. If we project that forward and include Wolfspeed, we can estimate MACOM reaching a run rate in the low $700 million range. With a 10% growth rate over the next few years, we could approach that billion-dollar revenue mark. Our projections suggest that achieving this is plausible around late '25 or '26, but reaching that goal would require substantial growth numbers. There are inherent risks, but as we plan and focus on proper execution, this remains our aim. We plan to expand our serviceable available market and introduce new growth avenues to our portfolio to help meet these goals. Importantly, we will not prioritize growth over profitability; our focus is on earnings per share. As I mentioned, we aim for $2.70 this year and have generated nearly $200 million in net income for the full year. As we progress over the next two to three years, we seek to grow both our top and bottom lines, supported by our business model. Our model leverages unique internal process technologies and products while operating in the merchant market using a fabless approach. We utilize the major foundries in the silicon sector such as global foundries, Tower Jazz, TSMC, and others. We believe we have a strong chance to meet our goals, but there are many challenges ahead.

Thanks, Steve. That's really helpful and then very quick clarification on the RF acquisition from Wolfspeed. Are there any regulatory impediments to closing that, or is it just getting the paperwork in order? Thanks.

So there were two regulatory hurdles which we've gone through. One is HSR waiting period, which expired, and the second was a UK approval, which was received. So after that, it's just making sure that Wolfspeed and MACOM do the final work on aligning so that when we close, we will be operational. And this is rather unique. Most companies would acquire a business and then integrate. We are organizing in a way to have a lot of planning up front so that when we close, it can be an instantaneous integration, so to speak, and so outside of that, there's nothing stopping this.

Thank you. And I see we have another question from Tore Svanberg from Stifel. Your line is now open.

Yes, just two quick follow-ups. So Steve, first of all, you commented a little bit on the laser business, but I know it's been a bit sort of fits and stops there. And I'm just wondering, is it a market issue? Is it a yield issue? Is it because the technology is so unique? Just trying to understand when the laser business could really start to grow.

So MACOM was very late to the market with our 25G DFB laser portfolio, and so I would put it in the category of timing, and then when we really had our portfolio established and we're selling it in the market, our timing just was not good in terms of generations and focus of a lot of the transceiver companies. We're starting to break through some of that, and we're starting to gain traction. So we don't see a performance issue. We don't see a yield issue. It's not a cost issue. It's really just knocking out the competition, so to speak, and that takes time and is taking more time than we had originally thought. The other thing I'll add is as we go into the next fiscal year, we are adding and we plan to add EMLs to the portfolio. So this will mean CW lasers, FP lasers, DFB lasers, and EMLs. We do not manufacture VCSELs, but the next add-on to the product line will be EMLs, which generally speaking are considered high-value lasers, and they generally command higher price points.

That's great, and one quick one for Jack. For turns this quarter, should we sort of assume a similar level as you achieved in the September quarter?

Yes, and I think you're referring to our turns business where we receive orders and ship them in the same quarter. We've been in the, I'd say, the mid-teens. So I think that's a safe assumption as we go forward.

Great. Thank you very much, and congrats.

Thank you. In closing, I would like to thank the entire MACOM team for their outstanding effort and commitment during fiscal 2023. MACOM is fortunate to have such hardworking and dedicated employees, which make these financial results possible. And we all look forward to welcoming the Wolfspeed team to MACOM. I'm confident that together we can achieve great results. Thank you.

Ladies and gentlemen, that does conclude our conference for today. Thank you for your participation. You may now disconnect.
