Good day, and welcome to the Ciena Fiscal Third Quarter two thousand and twenty-four financial results conference call. Today, all participants will be in a listen-only mode. Should you need any assistance during today's event, please signal for a conference specialist by pressing the star key followed by zero. After today's presentation, there will be an opportunity to ask questions. To ask a question, you may press Star, then one on a touch-tone phone. To withdraw your question, please press Star, then two. Please note that today's event is being recorded. I would now like to turn the conference over to Gregg Lampf, Vice President of Investor Relations. Please go ahead, sir. Thank you, Chris. Good morning, and welcome to Ciena's 2024 fiscal third quarter conference call. On the call today is Gary Smith, President and CEO, and Jim Moylan, CFO. Scott McFeely, Executive Advisor, is also with us for Q&A. In addition to this call and the press release, we have posted to the investor section of our website, an accompanying investor presentation that reflects this discussion, as well as certain highlighted items from the quarter. Our comments today speak to our recent performance, our view on market, the current market dynamics and drivers of our business, as well as a discussion of our financial outlook. Today's discussion includes certain adjusted or non-GAAP measures of Ciena's results of operations. A reconciliation of these non-GAAP measures to our GAAP results is included in today's press release. Before turning the call over to Gary, I'll remind you that during this call, we'll be making certain forward-looking statements. Such statements, including our quarterly and annual guidance, commentary on market dynamics, and discussion of our opportunities and strategy, are based on current expectations, forecasts, and assumptions regarding the company and its markets, which include risks and uncertainties that could cause actual results to differ materially from the statements discussed today. Assumptions relating to our outlook, whether mentioned on this call or included in the investor presentation that we will post shortly after, are an important part of such forward-looking statements, and we encourage you to consider them. Our forward-looking statements should also be viewed in the context of the risk factors detailed in our most recent 10-K and our 10-Q, which we expect to file with the SEC today. Ciena assumes no obligation to update the information discussed in this conference call, whether as a result of new information, future events, or otherwise. As always, we'll allow for as much Q&A as possible today, though we ask that you limit yourselves to one question and one follow-up. With that, I'll turn the call over to Gary. Thanks, Gregg, and good morning, everyone. Today, we reported strong fiscal third quarter results, including revenue of $942 million and adjusted gross margin of 43.7%. We also delivered quarterly adjusted operating margin of 8% and adjusted EPS of $0.35. Later in the call, Jim will provide additional details about our Q3 financial performance, highlights from the quarter with respect to our portfolio, and our outlook for the fourth quarter, and speaking of Jim, you will also have seen the news this morning that he's informed us of his decision to retire next year after more than 16 years with Ciena. Jim is obviously an outstanding member of our executive leadership team, and we look forward to him continuing as CFO while we commence a search process to identify a successor. On the state of our business, overall industry dynamics continue to be encouraging, and our innovation leadership has, frankly, never been more apparent. As expected, order flow in Q3 was strong, largely driven by cloud providers, and we finished the quarter with a book-to-bill ratio above one. We see this as a positive sign that the market is moving in the right direction, with the gap between supply and inventory absorption narrowing, and ultimately, bandwidth demand continues to be strong and is growing, particularly with the anticipated rise in AI-driven network traffic and increased cloud adoption. We are now clearly seeing customers move toward dedicated network capacity and architectures, initially to support AI for machine-to-machine type traffic. This brings me to my next point, which is that we believe it is most helpful to look at, really, the current environment through the lens of our two largest customer segments, cloud providers and service providers. Starting with cloud providers, they are clearly leading the charge in building out their networks to support the expected growth in cloud and AI-related traffic. Specifically, they are investing in their network architectures, from subsea cables to long-haul routes to data center connectivity, essentially to add capacity with the most efficient use of space and power. Our leading technology best addresses these key requirements, and combined with our deep and expanding relationships with cloud providers, our business with this customer segment is strong and getting stronger in all aspects. In Q3, we secured new wins with major cloud provider customers, spanning terrestrial, submarine, and coherent pluggable applications, the majority driven by preparations for the expected growth in AI and cloud traffic. For the same reason, we are seeing a growing market opportunity for us amongst the expanding set of cloud players, including data center operators and companies that offer a range of cloud applications and cloud infrastructure services, and we have, in fact, been winning an increasing number of these deals with these customers over the past several quarters. Now moving to service providers. Overall, our pipeline with service providers globally continues to increase, and we are winning significant deals, including many new logos. For example, in Q3, we secured new customers in India, South Asia, Germany, Scandinavia, and several new ones across North America. In addition, MOFN activity, which we mentioned last quarter, remains strong, with four major wins in Q3. And just as a reminder, with MOFN, telecom service providers build advanced optical networks and lease fiber pairs to cloud providers, really enabling them to quickly expand their reach and better service their customers. I would say that while these wins bode incredibly well over the longer term, our current results continue to reflect the challenges related to the timing and volume of service provider orders. Specifically in North America, we have started to see the purchasing patterns of service providers come back into more of a normal balance as they continue to deploy inventory buildup from prior periods. Obviously, this recovery remains gradual and will take several more quarters to play through completely, but we are absolutely seeing clear evidence of improvement here. Further, with respect to international service providers, cautious spending persists, and particularly in Europe, related to macroeconomic geopolitical concerns as well as industry structure issues. As a result, we expect the recovery in order volumes from international service providers to generally lag that of our North American counterparts. With that, in talking about the markets, I wanna move to a discussion of our portfolio, and specifically the technology advantages that we have in the market today, as well as our market expansion opportunities from our innovation leadership. In summary, our optical portfolio has never been stronger with our industry-leading coherent modem technology, optical line systems, and automation and network control software. Starting with our coherent modems and our latest generation WaveLogic 6 technology. Last week, I think many of you saw that we achieved the world's first 1.6 terabit wavelength data transmission across some 470 kilometers in a live network with our customer, Arelion. This is a clear demonstration that our WaveLogic 6 Extreme technology, the first of its kind in the world to leverage 3-nanometer technology in a telecom application, can deliver unprecedented capacity and performance, setting a new benchmark for the industry. We expect to benefit from a considerable time-to-market lead with our 1.6 terabit solution, particularly given that no other competitor has even announced plans for a solution beyond 1.2 terabit, and we already have orders from 23 customers for WaveLogic 6, a list that continues to grow, and we will recognize revenue in Q4 as we begin shipping. As AI traffic demands increase and do become more distributed, line systems that are reliable, maximize capacity on fiber, and most importantly, minimize power, are critical to forward-looking network architectures. For several years, we have been closely collaborating with leading cloud providers on the design of that next-generation line system. The result is our Reconfigurable Line System platform, often referred to as RLS. It is the industry's leading open line system that can manage bandwidth-intensive applications with greater scale, density, and programmability, all while consuming less space and, of course, power. As a result, RLS is now being deployed by all of the major cloud providers, as well as a growing number of service providers. In fact, it has quickly become the industry's line system of choice to form the foundation of their AI-optimized network architectures. Accordingly, we expect orders and revenue for RLS to increase over the coming quarters, which lays further track, quite literally, for future business with capacity adds over time. Finally, let me talk about our Navigator Network Control Suite, the most advanced network control software in the industry today. Some of you may remember this by its former name, MCP. As network architectures evolve to meet bandwidth demand driven by AI and cloud-based applications, they are also obviously growing in complexity. As a result, the need to automate the management and control of these networks has never been greater. Our Navigator Network Control Suite is designed to do just that, and it is the first, and currently the only, domain controller based on a microservices architecture to optimize scale and performance. It basically provides a single view across all network layers, optical, Ethernet, and IP, to coordinate lifecycle network operations all within a single software system. Moving on from our optical foundation technologies and with respect to our market expansion opportunities, we are seeing a growing and incremental opportunity inside and around the data center. Specifically, our foundational optical technologies can be leveraged in a variety of form factors, including pluggables and high-speed interconnect technologies, really to address a range of consumption models. In pluggables, we already have several significant wins. In fact, we're ramping revenue for 400ZR at cloud providers for around the data center applications, specifically, really short-reach data center interconnect. I would remind everybody that we've now won three of the top four cloud providers for 400ZR. As we mentioned last quarter, we are also the recipient of the first 800ZR award by any major cloud provider. In looking at opportunities for our interconnect portfolio inside the data center, we are collaborating closely with several cloud customers and ecosystem partners in this area, and expect this opportunity to develop and mature over time. We are also gaining traction in our market expansion opportunities around broadband access and coherent routing. In broadband access, as public funding is distributed, which admittedly is taking longer than expected, we would look forward to providing more customers a modular and open XGS-PON solution. This is grounded in the competitive advantage that we have with our optical technology, and is a cost-effective, flexible, and sustainable OLT solution that can address residential, enterprise, and mobility use cases. In coherent routing, the growing need for scale and cost efficiency across network domains to support increased traffic flows from new applications will continue to drive customers to converge the IP and optical layers, we believe, over time in the metro, and we are well-positioned to support them with our purpose-built, coherent aggregation routers. In summary, I'd say that we delivered a strong performance in Q3, and we remain encouraged by the improving industry dynamics. Cloud providers clearly continue to be strong. Spending dynamics among our North American service providers are gradually improving, while we remain cautious about international service providers generally. It is clear that our market leadership, driven by the strength of our innovation and time to market advantage, will continue to drive share gains and open up new opportunities over time. With that, I'll turn it over to Jim. Thank you, Gary. Good morning, everyone. As Gary stated, we delivered strong fiscal third quarter financial results. Total revenue in Q3 was $942 million. This included two 10% plus customers, one cloud provider and one service provider. Adjusted gross margin was 43.7%. Q3 adjusted operating expense was $336 million. Book-to-bill was greater than one, as we expected. With respect to profitability measures in Q3, we delivered adjusted operating margin of 8%, adjusted net income of $51 million, and adjusted EPS of $0.35 per share. In addition, we used $159 million in cash for operations. We have been engaged in a strategic realignment of our supply chain activities, including improvements in processes and systems, as well as changes in our vendor relationships to improve resilience. As a part of this transition and to facilitate inventory movement across our vendor base, we made a cash advance of approximately $175 million to one of our vendors, which will be recovered over the next few quarters. Adjusted EBITDA in Q3 was $99 million. Finally, we ended the quarter with approximately $1.2 billion in cash and investments. We repurchased approximately 600,000 shares for $29 million during the quarter, and we continue to target the repurchase of $250 million in shares by the end of fiscal year 2024. Turning to some portfolio highlights from the quarter. In optical, WaveLogic 5 traction continues. We shipped close to 12,000 WaveLogic 5 Extreme modems in Q3 and added another 12 customers, 9 of which are new logos for Ciena. We also continued to gain momentum with WaveLogic 5 Nano, 400ZR and ZR+, shipping a record number of pluggables in the quarter for revenue. We added 18 new WaveLogic 5 Nano customers, for a total of 122 to date. Also, in optical, Waveserver revenue in Q3 was up 29% year-over-year and 25% sequentially, with 7 new customers in the quarter. Our routing and switching business continues to gain momentum. In Q3, we secured 9 new broadband access customers across Europe and the U.S., increasing our global broadband customer count to more than 65, and our coherent routing solution, which leverages our coherent aggregation routers in combination with our WaveLogic 5 Nano pluggables and Navigator Network Control Suite, is also increasingly being selected by customers to replace outdated legacy IP solutions. Other portfolio highlights from the quarter include another good quarter for platform software and services, with revenue up 5% year-over-year, and Blue Planet revenue nearly doubled year-over-year. Turning now to guidance. For the fiscal fourth quarter, we expect to deliver revenue in a range of $1.06 billion-$1.14 billion. This would put us at about $4 billion in revenue for fiscal year 2024, in line with the guidance we provided in June. We expect Q4 adjusted gross margin to be in the low-to-mid 40s range. Gary spoke about our Reconfigurable Line System, which has the combination of intelligence and high capacity that makes it ideal for next-gen AI-driven networks, and we're selling a lot. This has a near-term effect on our gross margins, but as we sell the modems to provide capacity on these lines, our margins will improve. And we expect adjusted operating expense to be approximately $350 million. Looking ahead to fiscal year 2025, as is our normal practice, we will provide a detailed view of our expectations when we report our Q4 results in December. With that said, we previously indicated that fiscal 2024 would be a transition year, following a few years that were impacted by the unusual events of the pandemic that led to supply chain challenges and a subsequent snapback, resulting in outsized growth in fiscal 2023. We have also said that we believe using a 6%-8% compound annual growth rate is the best representation of our long-term revenue growth rate, which is faster than market growth based on current forecasts. This range, by the way, matches our revenue growth rate over a long period of years. We continue to believe that this is a reasonable and balanced view for the long term, keeping in mind that any one year's growth rate can be outside that range. Before we conclude our prepared remarks, I'll say a few words about my planned retirement. We understand that the investment community likes to have advance notice of the departure of a senior executive, and we are providing that notice today. Ciena is a great company. We have the best optical technology in the world, and our lead on the competition is growing. We also have a group of passionate and talented employees all over the globe who make Ciena a great place to work. It has been an honor to serve as Ciena's CFO, but more than that, it has been a tremendous learning experience, and it will continue to be, since I will be at Ciena for another year. We will start a search for Ciena's next CFO immediately, and I will work closely with my replacement to ensure a smooth transition. To close, we delivered a strong Q3. We're confident in achieving our fourth quarter guidance based on the momentum we see in our business and the wins we've discussed. We are optimistic about positioning to capture long-term opportunities and deliver profitable growth, expanding into the new areas of available markets over the coming years. With that, Chris, we'll take questions from the sell side analysts. Thank you. We will now begin the question and answer session. As a reminder, to ask a question, you may press star then one on your touchtone phone. If you are using a speakerphone, please pick up your handset before pressing the keys. If at any time your question has been addressed and you would like to withdraw it, please press star then two. At this time, we will pause momentarily to assemble our roster. Today's first question comes from Meta Marshall with Morgan Stanley. Please proceed. Great. Thanks so much. You know, maybe, Jim, just, you know, as you mentioned on the call, you had talked about kind of 6%-8% kind of being a good long-term guide. Just, you know, as we look at - as you look at fiscal twenty-five estimates as they are, you know, and they are within that range, is there a comfort that you have with kind of fiscal twenty-five estimates of The Street as they are? And then maybe second question, for Gary, just, you know, on the pluggables wins that you guys have had, you know, noting that you said that a lot of those were very short reach, you know, do you view the pluggables business that you're getting as additive to the business currently? Thanks. We won't comment on the twenty-five estimates out there today. I will say that we feel great about our position in the market. We think six to eight percent is a good long-term growth rate. It's gonna vary from that in any given year, as we've seen in the past, and I think we're gonna continue to take share, so all of those things are good for us, but we don't want to make a comment about twenty-five at this point in time. We just finished Q3. So, moving on to the second part of the question, the very short answer is yes. We view pluggables as an incremental TAM opportunity for Ciena. We've been most consistent about this. Most of that is gonna go into the short reach, where we really don't have much revenues at all right now, so that's basically it. We do not see it cannibalizing, you know, long haul or submarine, it, you know, where they're very complex and high performance system requirements. We're not seeing that. On the metro DCI, which is less than 10% of the total optical market, by the way, we are seeing again, incremental opportunities for us. And any cannibalization would be really into the metro part of that DCI. We're not seeing that gather shape, and any cannibalization will be there is more than made up by the incremental pluggable opportunity in the short reach and by the overall growing marketplace. Great. Thank you. Thank you, Meta. The next question is from Simon Leopold with Raymond James. Please proceed. Thank you very much. First of all, Jim, congratulations, and thank you for giving us a one-year notice. Appreciate that. Hate being surprised, and we'll miss you. So on the questions, first of all, I wanted to see if you could put some dimensions around the MOFN opportunity you, you've talked about, given that it's sort of buried in the telco, but it's somewhat indicative of cloud trends. That's my first question. As a follow-up, I wanted to see if you could comment on your broadband opportunities in light of an announcement yesterday from one of your competitors winning exclusivity, or at least claimed exclusivity, with a Tier One U.S. operator. Thank you. Simon, let me take the MOFN piece. You know, it's increasingly becoming a larger part of our service provider piece, in collaboration with the cloud providers around the globe, and it basically gives the cloud providers, you know, an opportunity to get to market quickly. Very often, they will define the architecture that they want delivered, and they'll specify Ciena, and that's happening around the globe, particularly in places like India, you know, which is obviously a large target market for the cloud providers. You know, it's difficult to get visibility to all of those deals, but I would sort of, you know, put a size on it to probably 10%-15% of our total service provider business is actually MOFN in some way, shape, or form. That would be, you know, our sort of best view of it, which together with our direct cloud provider business and the subsea business, you know, is getting us in that 40%-50% of our total business really is cloud, both direct and sort of indirect. That's our best sort of perspective on it. Very often, you know, in various countries, there will be a combination of different approaches by the cloud providers. Some may be dark fiber, they light themselves, some may be provision on just normal capacity, and some will be on the dedicated MOFN deals, which we're increasingly seeing a lot of the cloud providers lean towards. We are kind of uniquely placed around that, given our global footprint in most of the major carriers around the world, our deep relationships with the cloud providers, and particularly, you know, the highest market share of all of the submarine cable piece as well. You put all of that together, and we're somewhat uniquely positioned to address that market. And then finally, on the forward-looking perspective on the broadband access business, I'd say this, like, obviously our intentions in the marketplace is not to an individual customer, it's to a broad market opportunity. We're very excited about the value proposition that we're bringing to the marketplace in terms of virtualizing the OLT, integrating that into our coherent routing, adding that capability to our management suite that we talked about with Navigator. It's resonating well in the marketplace. We're up to 65 customer wins now, and we're adding quarter by quarter to that count. So it's much, much more broader play than any individual customer, and obviously, we're not gonna comment on one individual customer anyways. The other thing I'd say, though, is in the short term, it's obviously swimming right into the dynamics that are going on in the service provider space, so there's a bit of a headwind there, and probably accentuated a bit by the delay in BEAD funding. So there's been, you know, a bit of short-term headwinds, but we're quite set about the long-term potential. Thank you. Thank you, Simon. Thanks, Simon. Our next question is from Samik Chatterjee with J.P. Morgan. Please proceed. Hi, thanks for taking my questions. Maybe for the first one, if I can sort of ask you more about the order commentary that you had in your prepared remarks. You mentioned the book-to-bill tracking above one, which I think would largely be seen as positive from sort of what your expectations were last quarter, but you also sort of highlighted the more sort of limited improvement or a slow recovery you're seeing with the service providers, particularly internationally. So, I mean, can you just parse that out a bit in terms of the improvement orders between service providers and cloud, and did sort of the service provider order improvement come in below your expectations? I don't know if you've ever provided, like, in terms of the service provider exposure you have, how much is, how much should we think is North America versus international? I have a follow-up. Thank you. Clearly, our current order flows are driven mostly by the webscalerrs. But we do expect some improvement, particularly on North American service providers, in the near term, and we expect improvement in the international service providers next year. Just as a point of reference, our backlog grew to about $2.1 billion at the end of Q3. We think our order flow in Q4 will be at maybe slightly below our revenue call, so our backlog, we expect at the end of this year, will be $2 billion. We think that it'll be a little heavier than it is today around service providers, because we do expect some improvement in their order rates. Got it. Okay, and for my follow-up, we also continue to see this robust investment or CapEx cycle from the webscalerrs, and you talked about that being driven by or preparing for AI as well. How should we think about how much of that investment from the webscalerrs will be towards the pluggables or short reach versus, really directed more towards your systems, portfolio and more towards the sort of traditional portfolio that you have? How are you thinking about where does the AI preparedness benefit really come through on the portfolio side? Thank you. Yeah, I think if you think about the pluggable piece, you know, separate out, you know, buying plugs to stick in other devices other than a whole end-to-end system. We've been pretty consistent in what we said, that we think, you know, that that is a place that plays in the short reach metro DCI. And we also said that it would take longer for it to be a material piece of the industry or the business, and I think that's played out pretty accurately, and we're starting to see that come through in terms of financial results for us as we ship 400ZR plugs into that application. And again, as Gary said, that is net incremental for us because we largely haven't been exposed to that part of the webscaler networks. But I think the broader spend, though, I remind you that, you know, we participate with them on submarine applications, on their core network applications, and then back into the service providers through the MOFN exposure that we have. In those cases, those are large, complex networks. And, you know, the winning hand on those comes back to optical modems, line systems, and the control systems that go with them. And we think we have the best technology in all three of those dimensions, so we're gonna continue to take our unfair share of that spend opportunity out there. Thank you. Let me just Please go ahead. Let me just add to that. The vast majority of spend will continue to be on optical systems in the cloud space. The vast majority of spend, because exactly as Scott said, the complexity and the performance requirements of these large systems is what's driving the network traffic. Great. Thank you. Thank you. The next question comes from Amit Daryanani with Evercore. Please proceed. Yep. Good morning, and thanks for taking my question. I have two as well. Yeah, maybe to start with your, your October quarter guide for gross margins in the low- to mid-40%. I think you talked about you're seeing some mix impact by initially selling more line systems there. Could you just quantify what that impact is? Is it like 100 to 200 basis points headwind? And then do you see that normalize in fiscal 2025 as you start to sell more modems potentially, or is there a longer duration to normalize that? I won't comment about 25 today, but clearly the portion of line systems that we're selling today is very heavily weighted, and that's resulting in a gross margin impact. It's at least a couple of hundred basis points. I mean, I can't give you an exact number, but it's at least that kind of a number. Got it. And then, you know, on the telco side, you talked about just starting to see a recovery in North America and then EMEA being macro-driven, but a little bit weaker. So I was wondering if you could just talk a little bit more about what are you seeing in APAC, in India specifically, when it comes to telco spending. We're seeing strength in Asia-Pacific. You know, we've seen a number of wins, particularly in South Asia, places like Indonesia, Vietnam, et cetera. So we see that. And then new logos for us, we have very low market share there, so that's encouraging. In India, I think, you know, we're very bullish about India. We have number one market share there. We see good MOFN growth, as obviously the cloud is very focused on it. It's a little bit cyclical. They're sort of recovering from the investment in all of the 5G pieces, but we are seeing a lot of activity. So as we look out for the next one to three years in India, you know, again, we remain bullish. It was up a little bit, sequentially, quarter to quarter. It's gonna have some ebbs and flows, but I think, you know, we think that we're onto a strong cycle, you know, over the next one to three years in India. And Amit, I want to correct something I just said. In Q3, it's at least 100 basis points, not 200 basis points. Got it. Perfect. Thank you for that. And Jim, congrats on the retirement, but I will see you around at least here. Well, thank you. Thanks, Amit. And the next question is from Tim Long with Barclays. Please proceed. Thank you. Congratulations from me, too, as well, Jim. We'll miss you. Yeah, first one if I could, then I have a follow-up. I understand you don't want to get too into the fiscal '25 at this point, but, Jim, you did make some comments about kind of looking a little bit more normal, or maybe Gary did, after a strong '23 and a, you know, correction here in '24. When we look at next year or just going forward, do we think we're back towards more typical linearity in the business? You know, just as a go-forward comment, and then I have a follow-up after that. You're referring to seasonal linearity, Tim? Yeah. Seasonality, yes. Seasonality. Our business used to be very predictable as to its seasonal, the seasonal nature, because our business was mainly service providers. With the increase in the sales that we make to webscalerrs, as Gary said, it's 40%-50% of our business is driven by their activity, we've become a much less predictable company in terms of our revenue seasonally. We've had very strong first quarters, and then, you know, typically in the past, our third and fourth quarter were our biggest quarters. That can change with the webscalerrs. So really, I can't call our seasonality right now. And by the way, we haven't even completed our plan for next year, so I don't know what it's going to be. Okay, great. And then just, you know, kind of a two-part follow-up here. Two of the, you know, business lines looked a little, big, big changes quarter to quarter. So for Blue Planet, that jump, is there just a big deal in there or some kind of seasonality? And similarly, the drop in routing and switching, sequentially, so in both, either of those businesses where there's anything like kind of one time, in them, or are these more, normalized levels here? So firstly, on Blue Planet, Tim, it you know basically doubled from this time last year, but off a you know relatively small base. You know, we've been basically focusing Blue Planet on you know very specific applications around inventory orchestration. And that's been you know increasingly successful, so it's not just one big deal. We're very encouraged by what we're seeing with Blue Planet, and we'll talk more about that during the coming quarters. You saw the recent announcement with Lumen, which is you know I think good evidence of that, but we're seeing broad engagements across you know a more focused set of applications from Blue Planet, including things like network assurance. On the routing and switching, really, it, it, you know, I think that's more a function of the overall service provider, you know, challenges, and I think we are continuing to make good progress on routing and switching. We're seeing new logos, but I think it really, it's, it's, held back right now by the overall service provider challenges, particularly internationally. North America, I think, as we've talked about, I think is gradually improving. We're seeing clear evidence of that, including routing and switching. The challenge is more internationally and particularly in Europe. Okay. Thank you, guys. Thanks, Tim. The next question is from George Notter with Jefferies. Please proceed. Hi, guys. Thanks very much. I guess I wanted to ask about sort of the trend in your direct webscaler revenue. You've had a couple quarters in a row now that are a bit smaller relative to what was a couple quarters of really, really strong webscaler sales. So, I, you know, yet the narrative around AI, the narrative from you guys, I think, just sounds better and better and better, and I'm kind of wondering, you know, what's causing that sort of step down versus the run rates you were at a couple quarters ago. Is that inventory digestion? Maybe it's a function of not seeing the whole picture, and, you know, I've got to look more at your MOFN deals and sort of adjust for that. But how do you sort of explain that trajectory relative to the narrative? Yeah, George, I think that all of our business is gonna be project driven, including that with the webscalerrs, and there are gonna be ebbs and flows in their activity. So, you know, an increase or a decrease in any one given quarter does not necessarily make a trend. Clearly, as you've seen, though, our webscaler business over time has grown from, you know, virtually nothing to directly between 25% and 30%. And as we said, MOFN is MOFN plus submarine is another 15%, maybe 10% to 15%, so we're getting up to 40% to 50%. But I will say this, one of the things we are seeing is that with the demands on network that the webscalerrs are putting, they can't do all the work themselves. Even they can't do it all themselves. That's why they're turning to MOFN. And MOFN has increased pretty significantly over the past year or two, and so, that is something that adds to the picture and shows you that we're getting good growth with the webscalerrs. Got it. Great. And then just as a follow-up, you guys made a comment in the monologue about, you know, interconnect opportunities, I think, inside data centers and collaborating with several content providers. Could you talk a bit more about, you know, what the application is there and what exactly you guys are doing? First of all, George, when we talk about our interconnect business, there's really three parts to it. There's us selling our coherent modem technology that plugs to outside of our system business. There's us selling our virtual OLT plugs outside of our system business. And then there's the third one that you talked about, which is the opportunity of taking that technology and reapplying it inside the data center. That third one is, you know, a longer term opportunity. The first two are obviously shipping for revenue today. On that third one, you know, the dynamic that we see is as, the data rates between, at a high level, between GPUs increase, as the distances that they have to communicate increase because of the constraints of power, and as the cloud providers start to look at things like optical switching as a way to provide you know, interconnect at a lower cost and a lower power footprint, all those things push you to need higher performing optics to connect. And, you know, the physics will dictate that at some point in time, today's existing technology is just not gonna cut it, and you're going to have to bring to bear the techniques that, you know, the WAN has seen and coherent for the last couple of decades. There's the analogy of when the WAN went from ten gig to something greater than ten gig. And we firmly believe that's gonna happen. The question is when, and then what technology slice. So, you know, think of it at a really high level of taking those components, whether they be digital assist with DSPs or whether that be some of the capabilities that we have on analog, digital, and the electro optics, and applying it to just interconnecting inside the data center, interconnecting GPUs. Great. Thank you very much. Thanks, George. Our next question comes from Tal Liani with Bank of America. Please proceed. Tal, are you there? Oh, here we go. Yeah, Tal. Yes, I was on mute. Here we go. Thanks. Thanks, guys. Jim, we're gonna miss you. I wanna ask you two questions. Number one is cloud. So cloud was strong over the last. If you take a multiple year view, cloud was strong. And you did not participate in this debate of InfiniBand versus Ethernet. You were kind of external to that debate. So the question is, when you look at the cloud opportunity going forward, and take a three-year view, five-year view, is the opportunity for you. First, is the deployment gonna get stronger? Meaning, do you think the growth is gonna be higher than what we've seen the last three to five years in general? And second, is the opportunity for you getting bigger? Meaning, do you, are you gonna be in parts of the network that you were not there before, so you could see better growth in the next few years? So, I have another question, but maybe we can start with the cloud, because I think that it will, it does, it does define your stock and valuation, and, and I wanna better understand kind of your participation there. Thanks. Given the pace at which the cloud providers are building data centers, and given that there are an increasing number of webscaler players that are in the data center business and building out between those data centers, it seems very likely that the webscalerrs are going to grow as a percentage of our business over the next several years. So yes, I think that's, that's probably true. Now, are we gonna participate in places that we don't participate? Yes, I believe we will. We, as we said earlier, we don't really participate in the short reach metro business. That's just not been a place where we have won a lot of business. I think we will play in that space with our plugs. As we said, we have an 800ZR win, and I think we'll have more of those, and it'll be short reach and long reach, but short reach in particular. I also think there's a possibility inside the data center. Now, that's farther out, and we still have a lot of work to do to make sure that we can provide the technology that's gonna be needed inside the data center. We don't know when the transition will occur, but we do believe that we'll have a good opportunity to play there. So yes, we're gonna be in broader parts of the hyperscaler network, and including having a big part in the ultra long haul and submarine parts of their networks, as we do now. Got it. Okay, second question is about the broadband, and I'm gonna ask it in a sarcastic way, but, you know, I'm not a mean person. Why are you even in this business? This is a commodity-like... That's what we've learned the last few years, right? Commodity-like, it's about pricing. There are companies that have been doing it for a while. Why suddenly you increase participation in this fiber to the X, and why is this attractive for you? Yeah, I think, I think a couple of things. First of all, you know, you, you're right in the sense that if there was sort of just a continuum of yesterday's world, that's a very valid question to ask. But our hypothesis is that, you know, we're staring at a different world in the future, which is, fiber will continue to have, you know, continue to be more prevalent in the network. Capacities are gonna increase, and the technologies that you require to do that, you know, continue to play to our strength of the coherent optics, and that's playing itself out in the broadband access space. If you think about where the standards are going with hundred gig PON, it is, you know, a coherent technology. So, you know, the technologies are swimming to our sweet spot. We own the technology, we're vertically integrated, we have a great cost base there on the OLT side. And we're bringing, you know, a very, very innovative architecture to our customers to service that future looking demand. It's also the same customer base that we have. So, you know, same customer base, swimming towards the technology that we have strength in. We own the technology, and we're vertically integrated on. Those are the reasons why, and it's a big spend opportunity out there in the marketplace. So those are the reasons why we're targeting it. We're clearly a challenger, but we like the hand that we have. Do you think you can earn good margins on this business? Yeah, our margins today, like I said, we've got sixty-five, sixty-five customers today, and the margins on that today is, you know, in line with our corporate average margins. Got it. Okay. Thank you. Thank you, Tom. The next question comes from David Vogt with UBS. Please proceed. Great, guys. Thanks for taking the time, and Jim, congratulations. Maybe just a big picture question to start. You know, I don't wanna get into specifics on fiscal twenty-five, but against the long-term model of 6-8% growth in Gary's comments, that's clear that webscaler is gonna be a bigger part of the business. Can you help us understand, maybe before webscaler had taken off to the point that it did recently, how we should think about SP spending, either in aggregate or by region, given the lull that we've lived through for a number of years? And in the context of that, and Jim, to your point about the backlog, and systems being a bigger part of coming out of into revenue now, how should we think about that gross margin impact going forward, if we look at maybe history as a comparison? I know COVID was probably an unfair comparison when you ship a lot of transceivers out of backlog, and that helps gross margin, but just any kind of framework or guardrails you can kind of put around the different moving pieces over the longer term, not necessarily '25, would be helpful. Thanks. David, let me take the first part of that question, the overall sort of service provider dynamics. You know, I would say that they've certainly been challenging, you know, all the way through COVID, supply chain, and then this absorption, which I think has lasted longer than any of us would have certainly anticipated. But, you know, seeing through the smog of all of that, if you will, you know, service providers continue to be the primary delivery for all of this bandwidth, including all of the things like AI and cloud connectivity around the world. You know, and particularly when you talk about the last mile or so and on the mobile side. So, you know, service providers are certainly not going away. It's been very challenging around the dynamics that we all know from that. I think they are coming into balance. Particularly, we're seeing that in North America, where we expect, you know, it to be a, you know, continued gradual improvement. We're encouraged by what we're seeing. And certain international markets as well, you know, places like India, places like South Asia, for us, look good. Europe, I think, has some, you know, particular challenges around the structure of it, which will take time to, you know, resolve, but it's also got the tailwind there of Huawei replacement as well. So I do think you're gonna get back to a more normalized growth with the service providers going forward. I do, which, you know, builds into our underlying 6%-8%, David, as you mentioned. And just on the shape of our gross margins, they don't vary significantly across our customer base. Now, when we're a challenger going into a new market, sometimes we'll put a pretty competitive price on the table in order to get in. But over time, whether we're selling to a service provider or to a webscalerr, our gross margins by product are gonna be, you know, in the same range. Now, we have said that line systems, in particular, have lower gross margins than our modems, our capacity. And that's just a function of first cost in to our customers, and that's true whether it's a service provider or a webscalerr. And then you look at optical margins versus routing and switching margins. We believe over time, routing and switching margins are gonna be accretive to our gross margins. Software will be accretive to our gross margins, and services is accretive to our gross margins. So that's the shape, doesn't really vary across our customer base all that much. Has to do with mix and timing of the project. Great. Can I ask just a follow-up, Jim, mechanical question? I don't think I heard you say where you think inventory is gonna end up at the end of the year. Do you have a sense that you could share with us? Yeah. It ended the quarter at $937 million. I think it'll come down another $50 million or so by the end of the year, my guess. Great. Perfect. All right, perfect. Thanks, guys. Appreciate it. The next question is from Ruben Roy with Stifel. Please proceed. Thank you. I guess, Jim, just to follow up on that, so as you get through the inventory, exiting fiscal 2024, how would you assess inventory levels at that point? Pretty close to normal, or is there more work to do there? You're talking about '25 now? Yeah, going into 2025. Yeah, 2025. Yeah. Yeah. As obvious from the, you know, only a $50 million or so decrease in Q4, it's still elevated. We're still working through inventory and the big orders that we put on our supply chain over the past year and a half. We had, you know, we were two times turns or something like that. In the past, we were at as much as six times turns, and but I don't think we'll get back to six times turns. Given what's happened in our supply chain, we will likely keep more surplus components of key components in order to make sure that we can get through difficulties in the purchase of some of these components. I think we'll get back down to something like four and a half, maybe five times, but maybe not five times by the end of next year. Maybe it's gonna be more between four and four and a half by the end of next year. Thanks for that, Jim, and congrats on your future plans. I had a quick follow-up for Gary or Scott, just around the 400ZR short-reach DCI commentary. I was wondering. It seems to me like that's maybe a little bit more of a competitive set of products relative to, you know, where you've been in systems historically, and just wondering, you know, given the momentum there, for your products, if you could maybe just give us a few details around why you're winning. I assume you mentioned, you know, power is important, et cetera, but anything else we should think of around, you know, kind of why you're winning and what your visibility is, I guess, you know, for continued momentum in that seemingly important area of the market? Thank you. Yeah. So, just a reminder, our 400 gig ZR pluggable is based off of our WaveLogic 5 Nano. If you go back a few years, we had two alternative WaveLogic 5, one was Extreme, one was Nano. We consciously made the decision to introduce Extreme first and Nano second in the marketplace, and turned out to be the right decision based on, you know, our market share gains over the years. But it did mean that we did not intercept the first couple early movers in the marketplace on the 400 gig pluggables. Now, the original definition of 400 gig ZR was sort of the least common denominator from a performance perspective. What's happened in the marketplace, of course, with AI coming on gangbusters, is people are realizing that power is forcing data centers to be distributed further, and therefore, performance starts to be important again. So, you know, performance from a reach perspective and performance from a power perspective, in that form factor, is now what wins in the conversations. And I'd say after the first couple of awards in this sort of industry segment, we've had a tremendous win rate in terms of any of the competitive bids out there for this technology. I think we're gonna continue to have that going forward because of that performance advantage. I think there is a misconception there about plugs generally, you know. Not all plugs are equal. Right. Got it. Thank you. Thanks, Ruben. Thank you, everyone, for joining us today. We appreciate it. We look forward to catching up with folks, later today and over the coming weeks. Thank you. The conference is now concluded. Thank you for attending today's presentation, and you may now disconnect.
