Good day and welcome to Ciena Fiscal Third Quarter 2024 Financial Results Conference Call. Today all participants will be in a listen-only mode. [Operator Instructions] After today's presentation, there will be an opportunity to ask questions. [Operator Instructions] 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.

Thank you, Chris. Good morning and welcome to Ciena's 2023 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 Investors 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 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 market 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 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'll ask that you limit yourself to one question and one follow-up. With that, I'll turn it over to Gary.

Thanks, Greg, 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 the CFO, while we commence the search process to identify a success. 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 1. 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 towards dedicated network capacity and architectures, initially to support AI for machine-to-machine type traffic. And 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. So starting with cloud providers, they are clearly leading the charge in building out their networks…

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. Booked to bill was greater than 1, as we’d 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 mentors, 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 ‘24. 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, nine of which are new logos for CIEN. We also continue to gain momentum with WaveLogic 5 nano 400 ZR 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, wave server revenue in Q3 was…

Thank you. We will now begin the question-and-answer session. [Operator Instructions] And today's first question comes from Meta Marshall with Morgan Stanley. Please proceed.

Great. Thanks so much. You know, maybe Jim, just as you mentioned on the call, you had talked about kind of 6% to 8% kind of being a good long-term guide. Just as we look at, as you look at fiscal ‘25 estimates as they are, and they are within that range. Is there a comfort that you have with kind of fiscal ‘25 estimates of the street as they are? And then maybe second question for Gary, just on the pluggables wins that you guys have had, noting that you said that a lot of those were very short reach. Do you view the pluggables business that you're getting as additive to the business currently? Thanks.

We won't comment on the ‘25 estimates out there today. I will say that we feel great about our position in the market. We think 6% to 8% is a good long-term growth rate. It's going to vary from that in any given year, as we've seen in the past. And I think we're going to continue to take share. So all of those things are good for us, but we don't want to make a comment about ‘25 at this point in time. We just finished Q3.

So, Meta, on 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 going to 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 long-haul submarine, where they're very complex and high performance system requirements. We're not seeing that. On the metro PCI, 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.

And 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, I 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'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 announcement yesterday from one of your competitors winning exclusivity, or at least claiming the exclusivity with a Tier 1 U.S. operator? Thank you.

Simon let me take a 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, which is obviously a large target market for the cloud providers. It's difficult to get visibility to all of those deals, but I would sort of, you know, put a size on it of probably 10% to 15% of our total service provider business is actually moat on in some way, shape, or form. That would be, you know, 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% to 50% of our total business really is cloud, both direct and sort of indirect. That's our best sort of perspective on it. And very often, you know, in various countries, there will be a combination of different approaches by the cloud players. Some may be dark fiber, they like 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. And 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 the highest market share of all of the submarine cable piece as well. So you put all of that together and we're somewhat uniquely positioned to address that market.

And then Simon 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 broader play than any individual customer, and obviously we're not going to cut 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 deed funding. So there's been a bit of short-term headwinds, but we're quite excited about the long-term potential.

Thank you.

Thank you, Simon.

Thanks, Simon.

Our next question is from Samik Chatterjee with JPMorgan. 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 build tracking of a 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 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? And I don't know if you ever provided like in terms of the service right exposure, do 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 webscalers. 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 flowed in Q4 will be at maybe slightly below our revenue cost. 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.

Okay, and for my follow-up, we also continue to see this robust investment or CapEx cycle from the webscalers 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 webscalers 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 you're thinking about where does the AI preparedness benefit really come through on the portfolio side, thank you?

Yes, I think if you think about the pluggable piece, separate out 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 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 true in terms of financial results for us as we ship our 400 gig ZR 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 webscale networks. I think the broader spend though, I remind you that we participate with them on summary 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 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 going to continue to take our unfair share of that spend opportunity out there.

Okay, thank you. Thanks for taking the question. Please go ahead.

Samik just to 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 their network traffic.

Great, thank you. Thanks for taking the question.

And the next question comes from Amit Daryanani with Evercore. Please proceed.

Good morning and thanks for taking my question. I have two as well. You know, maybe to start with your October quarter guide for gross margins in the low to mid-40%, I think you talked about you're seeing some mixed impact by initially be setting more line systems there. Could you quantify what that impacted, is it like 100 to 200 basis points headwind? And then do you see that normalized in fiscal ‘25 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 200 basis points. I mean, I can't give you an exact number, but it's at least that kind of number.

Got it. And then, you know, on the telecom side, you talked about just starting to see a recovery in North America and then EMEA being macro-driven, but a little bit weaker. Why don’t you just talk a little bit more about what you see in APAC and 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 Southern 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 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, again, we remain bullish. It was up a little bit sequentially quarter-to-quarter. It's going to have some ebbs and flows, but I think we think that we're onto a strong cycle 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.

Perfect, Thank you for that. And Jim, congrats on the retirement. But I'm glad we'll see you around for this year.

Thank you.

Thanks, Amit.

And the next question is from Tim Long with Barclays. Please proceed.

Thank you. Congratulations for me too as well, Jim. We'll miss you. Yes, 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 strong ‘23 and a 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?

Yes, seasonality, yes.

Seasonality. Our business used to be very predictable as to its seasonal nature, because our business was mainly service providers. With the increase in the sales that we make to webscalers, as Gary said, it's 40% to 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 typically in the past, our third and fourth quarter were our biggest quarters. That can change with the webscaler. 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 kind of a two-part follow-up here. Two of the business lines looked a little, 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, basically doubled from this time last year, but off a, you know, relatively small base, we've been basically focusing Blue Planet on 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 a more focused set of applications from Blue Planet, including things like network assurance. On the routing and switching, really, you know, I think that's more a function of the overall service provider, 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 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 than particularly in Europe.

Okay, thank you guys.

Thanks, [Indiscernible].

And 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 webscale 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 webscale sales. So, you know, you have 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 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?

Yes, George, I think that the business, all of our business is going to be project-driven, including that with the webscalers. And there are going to 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, a webscale business over time has grown from 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 saying is that with the demands on networks that the webscalers are putting, they can't do all the work themselves. Even they can't do it on themselves. That's why they're turning 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 with the webscaler.

Got it, great. And then just as a follow-up, you guys made a comment in the monologue about interconnect opportunities, I think inside data centers and collaborating with several content providers. Could you talk a bit more about 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 mode of technology that has 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 a longer term opportunity. The first two are obviously shipping for revenue today. On that third one, the dynamic that we see is those the data rates 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 lower power footprint. All those things push you to need higher performing optics to connect. And the physics will dictate that at some point in time today's existing technology is just not going to cut it, and you're going to have to bring to bear the techniques that the WAN has seen and we're hearing for the last couple of decades. It's an analogy of when the WAN went from 10 gigs to something greater than 10 gigs. We firmly believe that's going to happen. The question is when? And what technology slice? So think of it at a really high level of taking those components, whether they’d be digital sys with ESPs 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?

Tal?

Here we go. Yes, I was on mute. Here we go. Thanks, guys. Jim, we're going to miss you. I want to 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 going to get stronger? Meaning, do you think the growth is going to 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 are you going to 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 does define your stock and valuation and I want to better understand kind of your participation there? Thanks.

Given the base at which the cloud providers are building data centers and given that there are an increasing number of webscale players that are in the data set of business and building out between those data centers, it seems very likely that the webscalers are going to grow as a percentage of our business over the next several years. So yes, I think that's probably true. Now, are we going to participate in places that we don't participate? Yes, I believe we will. We, as we’ve said earlier, we don't really participate in the short-reach metro business. That's just not the 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 800 ZR 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 going to 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 going to be in broader parts of the webscaler network, 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 going to 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?

Yes. I think a couple of things. First of all, 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 we're staring at a different world in the future, which is fiber, we'll continue to have -- continue to be more prevalent in the network. Capacities are going to increase. And the technologies that you require to do that, continue to play towards strength coherent optics, and that's playing itself out in the broadband access space. If you think about where the standards are going with 100-gig on it take a coherent technology. So the technologies are swimming to our sweet spot. We own the technology. We're vertically integrated. We will have a great cost base there on the OLT side. And we're bringing 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 same customer base swimming towards the technology that we have to strengthen. We own the technology and ready to integrate 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.

And do you think you can earn good margins on this business?

Yes. Our margins today -- on 65 customers today and the margins on that today is in line with our corporate average margins.

Got. It. Okay, thank you.

Thank you, Tal.

And the next question comes from David Vogt with UBS. Please proceed.

Great guy. Thanks for taking the time and Jim, congratulations. Maybe just a big picture question to start. I don't want to get into specifics on fiscal '25. But against the long-term model of 6% to 8% growth in Gary's comments, that's clear that webscale is going to be a bigger part of the business. Can you help us understand maybe before webscale 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 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 shipped 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. I would say that they've certainly been challenging all the way through for COVID supply chain and then this absorption, which I think has lasted longer than any of us would have certainly anticipated, but seen through the smog-gable of that, if you will, 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. And particularly when you talk about the last mile or so and on the mobile side. So 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 it to be a continued gradual improvement. We're encouraged by what we're seeing, and certain international markets as well, places like India, places like South Asia for us, look good. Europe, I think, has some particular challenges around the structure of it, which will take time to resolve. But it's also got the tailwind there of Huawei replacement as well. So I do think you're going to get back to a more normalized growth with the service providers going forward, I do, which builds into our underlying 6% to 8%, David, as you mentioned.

And just on the shape of our gross margins, there -- the shape of our gross margins don't vary significantly across our customer base. Now when we're a challenger going into a new market, sometimes we'll sort of a pretty competitive price or they order to get in. But over time, whether we're selling to a service provider or to a webscaler, our gross margins byproduct are going to be in the same range. Now we have said that line systems, in particular, have lower gross margins than our MOFN or 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 webscaler. And then you look at optical margins versus routing and switching margins. We believe over time, routing at switching margins are going to be accretive to our gross margins. Software will be accretive to our gross markets and services is accretive to our gross market. 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 going to end up at the end of the year. Do you have a sense that you can share with us?

Yes, ended the quarter at $937 million. I think it will come down another $50 million or so by the end of the year, I guess.

Great. Perfect. Alright, 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 '24, 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.

Yes, going into ’25.

Yes, perfect, yes. Yes, [Indiscernible] $150 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 1.5 years. We were a couple of 2 times turns or something like that. In the past, we were at much as 6 times turns. But I don't think we'll get back to 6 times turns. Given what's happening in our supply chain, we will likely be 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 4.5 times maybe 5 times, but maybe not down by the end of next year, maybe it's going to be more between 4 and 4.5 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 400 ZR commentary. I was wondering -- it seems to me like that's maybe a little bit more of a competitive set of products relative to where you've been in systems historically? And just wondering, 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 power is important, et cetera. But anything else we can you think of around kind of why you're winning and what your visibility is, I guess, for continued momentum in that seemingly important area of the market. Thank you.

Yes. So just a reminder, our 400 gig ZR plug is based on where we've landed 5 nano technology, if you go back a few years, we had two alternative WaveLogic 5 ones, Extreme one was nano, we consciously made the decision to introduce Extreme first and nano second in the marketplace. And turned over to be the right decision based on our market share gains over the years, but it did mean that we did not intercept the first couple of 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 as people are realizing that power is forcing data centers to be distributed further and therefore, performance starts to be important again. So performance from a reach perspective and performance from a power perspective in that form factor is now what wins in the conversation. 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 being in the competitive bids out there for this technology. And we're going to continue to have that going forward because of that performance advantage.

Then I think there is a misconception there about plugs generally -- 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 has now concluded. Thank you for attending today's presentation, and you may now disconnect.
