Thank you, Gero. Good afternoon, everyone, and thank you for joining our call today. We are delighted to report an outstanding fourth quarter that ended a remarkable year of accelerating year-over-year revenue growth. and we are enthusiastic that our momentum will extend in the first quarter and through fiscal year 2027. Fourth quarter revenue of $1.316 billion increased 45% year over year and exceeded the top end of our guidance range. This revenue upside flowed through to the bottom line with non-GAAP EPS of $4.10 which was also above our guidance range. We were pleased to see success from multiple sustainable growth drivers simultaneously supporting our business as we closed out Fiscal 2026, and we are excited to anticipate an even stronger Fiscal 2027. For all of fiscal 2026, revenue was an impressive $4.6 billion, increasing 36% from fiscal 2025. And with strong execution, net income grew even faster than revenue, producing non-GAAP EPS of $14.09 for the year. What's most noticeable to us is that this performance did not come from any one product category or customer, but from increasing demand trends across numerous customers in multiple markets. Particularly evident are customers addressing the data center market as well as those serving the communications infrastructure market. Demand from these markets continues to increase which makes us optimistic about the long-term durability of these trends. Before we get into the details of our results, I'd like to highlight a change in the way we will be reporting our revenue breakdown going forward. As complex optical and electronic products become more and more prevalent inside, across, and between data centers, it is evident that hyperscalers and other data center service providers are the ultimate customers of many of the products we manufacture, including some of those that have been characterized as telecom products in the past. At the same time, communications infrastructure continues to be an important part of our business, driven by general-purpose, longer-reach products with broader applications that are not specific to data centers. Therefore, in order for our revenue breakdown to better reflect the end markets we ultimately serve, going forward, we will focus on three revenue categories. Number one, data centers. Number two, communications infrastructure. And number three, automotive, industrial, and other revenue. In addition to being better aligned with the markets we ultimately serve, this also simplifies our reporting. We will continue to provide color on trends within all of these categories to extend our transparent revenue reporting practices and to help investors better understand the underlying drivers of our business. I would now like to talk about capacity. As you know, we have been rapidly increasing our manufacturing footprint in order to stay ahead of rising demand, and we are excited to report a number of milestones. At Building 10 in our Chonbury campus, we remain on track to complete Building 10 by early 2027, which will add a total of 2 million square feet to our footprint. We have already qualified 250,000 square feet on the first floor of this facility, and we expect a similar amount on the third floor to be qualified this quarter. At our Pinehurst campus, we have completed the conversion of 120,000 square feet of office space into manufacturing space. We have also completed the acquisition of our new site in Navanacorn earlier in the fourth quarter, And we are happy to report that this building has just been commissioned, adding another 200,000 square feet of space. In addition to these capacity increases in Thailand, we have also been focused on expanding our footprint at Fabernet West. Our Santa Clara operations are primarily focused on helping customers, many of which are in the same neighborhood, bring new products to market. Since Fabernet West is an on-ramp to Bangkok, success here is measured by how efficiently we transfer production of products to Thailand for higher volume, low-cost manufacturing at scale. To support increasing demand for these new product introduction and related services, we recently completed the acquisition of a campus at Great America Place in Santa Clara, less than a mile away from our existing facility on Patrick Henry Drive. This campus consists of two office buildings and a large manufacturing space of approximately 130,000 square feet that will more than double our Silicon Valley footprint and help support our long-term growth. Looking back at fiscal 2026, it was a remarkable year with accelerating revenue growth and record profits. More importantly, we have set the stage for another incredible year in fiscal 2027 as our strategy plays out. In addition to increasing demand across our existing business, we will see our growth bolstered by recent program wins as we continue to pursue further opportunities across our key markets. In summary, this is an incredible time at Fabernet as we benefit from our focus on complex, high-growth markets, and we are proud to be winning more than our fair share of the opportunities. With accelerating year-over-year revenue growth, we are enthusiastic about the strong demand trends we are seeing and confident in our ability to extend our strong track record into the new year. Now I'd like to turn the call over to Ciava for more details on our fourth quarter results and our outlook for the first quarter of fiscal 2027. Ciava.
Thank you, Seamus, and good afternoon, everyone. We delivered an excellent fourth quarter with year-over-year revenue growth accelerating to 45% and continued strong earnings growth. Revenue reached a record $1.316 billion above the high end of our guidance range. We also continued to generate operating leverage, resulting in record non-GAAP EPS of $4.10, which also exceeded our expectations. As Seamus described, we have updated our revenue mix reporting to better reflect the end markets we serve and where our customers' products are ultimately deployed. The investor deck posted on our website provides a 12-quarter history under the new reporting structure along with the reconciliation of our Q4 results to the prior categories. This change is purely presentational and has no impact on total revenue in any period. Now, turning to the details, beginning with data center revenue. This category includes optical and interconnect products deployed within data centers, including data center networking with an expanded view of DCI, high-performance computing, and other AI infrastructure applications. Data center revenue was $669 million in the fourth quarter, representing growth of 68% from a year ago and 13% from Q3. This is now our largest category, representing 51% of total revenue. PCI products were the largest contributor to data center growth in the fourth quarter, with an annualized revenue run rate exceeding $1 billion. High-performance computing, or HPC, also made a substantial contribution to data center revenue, with solid growth in the quarter. Looking ahead, we expect the momentum we saw in the fourth quarter to continue into fiscal 2027. Support is further by the new transceiver we discussed last quarter. Moving to communications infrastructure. This category includes optical and networking products used in telecommunications and enterprise networks, excluding products specific to data center applications. Revenue was $413 million, an increase of 40% from a year ago and 1% from Q3, representing 31% of total revenue. Growth was broad-based across customers and end markets, including telecom systems, satellite communications, and telecom components. We remain optimistic about the long-term growth outlook for this market and expect continuous trend in fiscal 2027. Turning now to automotive, industrial, and other category. Revenue was $234 million, up 8% from a year ago and 9% from Q3, representing 18% of total revenue. The improving sequential growth was primarily driven by EV charging infrastructure products with a smaller contribution from growth at certain LIDAR customers. Overall, we are extremely excited about the growth trajectory and the broad-based trend in demand across the customers and end markets we serve. As I discuss the details of our P&L, all expense and profitability metrics will be presented on a non-GAAP basis unless otherwise noted. Cross margin in the fourth quarter was 12.2%, a 10 basis point improvement from Q3 and a 30 basis point decline from a year ago. We continue to demonstrate strong operating leverage with operating expenses representing just 1.3% of revenue. This produced an operating margin of 10.9%, our highest level in three years. I'll remind you that our growth model does not require significant incremental operating expense, and we therefore expect continued operating leverage as revenue grows. Interest income was $7 million, and we saw a foreign exchange evaluation gain of $1 million in Q4. Income tax was $3 million in the quarter. Gap net income was $139 million for $3.83 for diluted share. Non-gap net income was $149 million dollars or four dollars and ten cents per diluted share in calculating our queue for non-gap earnings we excluded two items that we believe provide useful information to investors in assessing our results and comparability across periods first we recorded an approximately fifty six point seven million dollars non-cash gain from remeasuring our investment in rating this was an accounting gain on an existing investment and did not generate cash for the business. We intend to apply the same treatment consistently to the future gains or losses from re-measurement of this investment. Second, we recorded $57.4 million provision related to Thailand's top-up tax regime under the OSC de Global Minimum Tax Framework. The provision reflects the first-year application of the new framework and is based on the rules in effect that our fiscal year ran. No cash was paid in fiscal 2026 in connection with this transition. Thailand's regulatory environment for this tax remains in transition as implementing regulations, guidance, and related investment support measures continue to develop. As a result, future tax expense and any related benefits could vary over time and we intend to apply a consistent approach while the transition continues. For the full fiscal year, revenue was a record $4.6 billion, up 36% from fiscal 2025. Non-GAAP EPS was $14.09, an increase of 39% from a year ago. In 2026, we continue to diversify our customer base, with four customers representing 10% or more of total revenue. These were Cisco at 20%, Nvidia at 16%, Nokia at 11%, and Amazon at 11% of total revenue. Turning to our balance sheet, we ended the fourth quarter with cash and short-term investments of $876 million, down $70 million from the end of Q3. Operating cash flow for the quarter was $55 million. CapEx increased to $92 million with ongoing construction of building 10 in Chonbury and the purchase of our new campus in Navanacorn for $11 million. Free cash flow was an outflow of $37 million in the quarter. For the full year, operating cash flow was $257 million and free cash flow was $4 million. This reflects our disciplined capital allocation strategy and our continued investment in capacity to support long-term growth. We believe reinvesting in the business remains one of the most attractive uses of our cash, supporting continued growth by generating strong ROIC. In the fourth quarter, we did not repurchase a meaningful number of shares. However, our share repurchase program remains active with approximately $169 million available at the end of the quarter under our current authorization. Turning to our fiscal Q1 2027 guidance. As we look to the first quarter, we enter the new fiscal year with strong momentum across the business. In the data center market, we anticipate strong broad-based growth across transceivers, DCI, and high-performance computing products. We expect growth from both established programs and newer wins, providing multiple growth engines for the company. In communications infrastructure, we also expect healthy growth, supported by continuous strong demand across a broad range of systems, components, and other programs. We are also optimistic that we will see growth in automotive, industrial, and other revenue. In total, we expect first quarter revenue to be between $1.375 and $1.425 billion. representing year-over-year growth of 43% at the mid-force. While our usual first quarter expense seasonality will create a temporary margin headwind, we expect to continue generating operating leverage as revenue grows. As such, we anticipate EPS to be between $4.10 and $4.25. While we only guide one quarter at a time, we think it's important to convey that we are more confident than ever in our longer-term outlook as customers provide us with visibility that goes into fiscal 2027 and beyond. While these longer-term customer forecasts are not order commitments, they reinforce our confidence in the durability of the very strong demand trends we are seeing. In summary, our outstanding fourth quarter results capped a remarkable year for the company, with revenue increasing 36% and EPS growing 39%. We enter Fiscal 2027 with strong momentum driven by growing demand across existing programs, meaningful contributions from new program ramps, and additional capacity coming online to support continued growth. Operator, we are now ready to open the call for questions.

Thank you so much. And as a reminder, to ask a question, simply press star 11 on your telephone and wait for your name to be announced. To remove yourself, press star 1-1 again. One moment for our first question. It comes from Christopher Rowland with Susquehanna. Please proceed.
Yasha
Analyst — Susquehanna
Hi, this is Yasha on for Christopher Rowland. Thank you for taking my question. So I wanted to ask on Datacom. It was down slightly sequentially in the quarter. So can you help us understand the dynamics there? How much of that was component supply versus any program transition or demand timing? And as we look into September and beyond, how should we think about the shape of datacom recovery? Do the constraints ease in any way to frame like sequential or year-over-year growth?
Hi, this is Ciaba. Let me take that question first. So we are transitioning to our new revenue categories, as we mentioned in our prepared So if you were to look at and to reconcile our Q4, our datacom was somewhat flat. Obviously, this is a combination of everything that you have mentioned. And when we are looking at this category in our data center business in the future quarter, we do anticipate this to be up sequentially in our Q1 guidance. So the demand environment remains pretty robust and accelerating. So we are very optimistic about this subcategory that we are now going to report inside our data center revenue category.
Yasha
Analyst — Susquehanna
Thank you. And then my second question is on HPC. I think previously you had talked about a $150 million quarterly run rate for September. So is that still the expectation for the next quarter, or maybe has the timing there kind of shifted? And I think in your preparer remarks, you highlighted new transceiver wins with this customer. So any additional color there, is this for 800 gig, 1.6 T, or any other color on, like, applications?
Yeah, this is Seamus. Yes, our, you know, our HPC business continues to perform, I would say, ahead of expectations. We demonstrated good sequential growth in the quarter as, you know, a number of programs with the major hyperscaler continues to ramp. We're in the process of ramping the customer's next generation silicon platform, and we're installing additional capacities to support both the technology transition, as well as additional products and capacity that we're adding additional products that we'll be manufacturing we remain on track with the customer and we expect that business to continue to grow you mentioned the let's say the transceiver business as well with that particular customer so we're excited to be expanding our data center transceiver business with with a number of new customers and programs we expect these programs to see we expect these programs to start ramping as soon as this quarter with the hyperscale or direct program among the first to launch the one you mentioned we do expect one of the merchant programs to begin in the December quarter and and the others you know to get off the ground in early calendar 2027 this is this is all pretty consistent with our prior expectations for a meaningful ramp over the course of the fiscal year, supporting our very strong growth trends.
Operator
A moment for our next question, please. It comes from George Notter with Wolf Research. Please proceed.
Thanks very much. I wanted to ask about some of the capacity additions in the business. Obviously, we're getting ready to wrap up Building 10 in the next few months. I'm just curious on your thoughts around Building 11. I think, Seamus, if you go back in time, I think you admitted at one point that maybe you started building 10 a little bit too late. I guess I'm just wondering how you think about the triggers now for building 11 and then longer term capacity additions.
No, I think we started building 10, as it turns out, at exactly the right time, either by excellent planning or good luck or a combination of both. Yeah, we continue to expand our capacity ahead of the demand. and you know investing in capacity for us is a very important use of the cash and we're really rapidly expanding our manufacturing footprint to support the strong the strong customer growth that we're seeing and to make sure we have sufficient capacity for for the new programs just to kind of frame it uh a little bit we we ended um fiscal 2025 if you take q4 revenue of 1.32 billion, multiply that by four, you get about 5.3. So we're at a run rate of 5.3 billion. So a little bit ahead of what we had originally thought, you know, was the capacity. So 5.3 billion run rate as we execute Q4. And we have, if you like, land capacity and plans in place to bring that capacity up to between 12.5 and 14 billion over the coming years. And let me just explain how we get from 5.3 to potentially 14 again we finished FY 26 at a run rate of 5.3 with with the space we converted in Pinehurst recently that would take us up to about between 5.5 and 5.8 we converted some office space into manufacturing so that takes up to you know 5.5 to 5.8 building 10 will add three to three and a half billion of capacity so that would take us to between 8.5 and 9.3 i know that's a pretty broad range but it really does depend on the mix and that and that the products that we're making for our customers so like i said building 10 will add about three to 3.5 taking us up to between 8.5 and 9.3 uh we've already started to produce in in some of uh just started you know to produce in some of building 10 but you know the vast bulk of that capacity add is in front of us uh the nirvana corn factory that we recently purchased uh that will start contributing from q1 onwards um and and at full capacity that building has capacity for about another 200 250 million um santa clara the new campus you know again it's very much very much mix dependent but if you just take the kind of the average revenue per square foot and apply it that Santa Clara campus would add about 200 to 250 million of additional capacity and then we have room to build two more factories in Chonbury each of about 1.2 million square feet with revenue capacity of about 1.8 to 2.1 billion so if you add up all of that and you take the you know the low and the high of each of those additions, you get between 12.5 and 14 billion. And we continue to look for more land to expand. So we've been very fortunate. We've been able to keep expanding ahead of the demand, and we plan to continue to do that. We're going to be expanding, continuing to expand aggressively over the next few years.
Got it. Super. And then I think last quarter when you discussed this, I think you kind of circulated or centered on a an eleven and a half billion dollar revenue run rate if I'm correct these numbers are obviously higher is it just the difference is obviously a piece of this I think is Nava but are there Santa Claire would be another piece are there other components in this also or no yeah I think it's a combination of we're adding more you know more space more square footage of course between Nava and the other the other capacity dishes We talked on Santa Clara, of course, but also, you know, our revenue per square foot is increasing.
We are actually increasing our revenue per square foot. We're doing we're doing more with less. We find we seem to always find ways to make sure we never we never turn away revenue. We don't we don't disappoint the customers. So we always find ways to get the, you know, the product out. So our revenue per square foot has been increasing as well as our our square footage has been increasing. So both have been increasing.
Operator
Thank you. One moment for our next question. It comes from Joseph Cardoso with JPMorgan. Please proceed.
Hey, good afternoon, and thanks for the question. Maybe just one on the discussion in recent weeks around CPO and MPO, and maybe more specifically about the MPO opportunity. It seems like it's materializing a bit sooner than what maybe the industry or at least maybe investors have been thinking about. And I'm just curious, just given the combination of the recent relationship that you have with RayTech, you know, how are you thinking about Fabernet's ability to address these type of opportunities? I mean, I guess CPO and NPO, but I'm just curious if NPO is looking like it's something that maybe is happening earlier for you guys and maybe to a greater magnitude than what was thought a quarter or two ago. And then I have a quick follow-up.
Sure. Thanks, Joe. Yeah. So, you know, NPO technology sits somewhere between pluggables, pluggable modules and CPO. As you know, we've built tens of millions of pluggable modules over the years. So we've clearly demonstrated that expertise. We're working on, you know, CPO today with a handful of customers, and we're already building devices, albeit not yet, at full-scale volumes. And, you know, since NPO, as you said, NPO combines elements of both, we feel we're very well positioned to be the leader in manufacturing and packaging near packaged optics devices. As NPO scales to 6.4, 12.8, terabit and beyond, the manufacturing complexity and yield becomes increasingly important. It becomes critical. And, you know, for decades, our core strength has been transforming advanced photonics components into reliable high volume systems. So that's really what we do. That's our sweet spot. it's probably too early to talk about let's say revenues and margins from those opportunities and customers as they depend on program specifics but rest assured we are very much involved in in all of the technologies you mentioned and NPO I think probably represents a more near-term opportunity than CPO for what we've seen with our customers our partnership with Raytech we think will be you know very important for us and will really be instrumental in allowing us to unlock the potential of the demand we're seeing ray tech will be adding a capacity in Thailand in our in our campus so you know we really feel it's important for us to have all of the all of the packaging capabilities that are required to produce these these products of the future under under our roof either in our own production lines are in partnership with that with ray tech. So, we're pretty excited about those opportunities, Joe.
No, no. Thank you. Very interesting. And then maybe just as my follow-up, you listed Nokia as a 10% customer, which maybe for me was a bit of a surprise. I thought maybe Sienna would be on that list. But maybe just speaking to Nokia, how much of this is a function of the Infantara business that you've had as a large customer, at least historical, versus maybe additional business that you have subsequently won as a function of the, you know, the combination of those two companies together. Just curious if you're actually seeing the business, you know, you now winning bigger or more opportunities from the combined entity, or if it's more just a function of what you had done historically with Infinera and kind of a rising tide situation.
It's a little bit of both, you know, I mean, I don't want to go into too much details on any one specific customer, but I think I can, I can safely say, you know, our first objective, and it's something we don't necessarily control, was to make sure that we do everything possible, that when Nokia acquired Infinera, that the Infinera business, you know, stays robust. And sometimes in these situations, when the big company acquires a smaller company, there can be product rationalizations and things like that. And through no fault of your own, you can end up losing business. That didn't happen in this case. You know, the Infinera products, I think, are instrumental and, you know, seem to have very strong demand. So the Infineira business has been rising. And then, of course, the Nokia business is going very strong as well. And our relationship with Nokia is very good. We historically have done a little bit of business with Nokia, but they were not a big customer for us historically. So really that reputation that we had and that we continue to have with the Infineira folks has really stood us in good stead. And we feel we're well positioned and starting, as you say, to make some breakthroughs in winning business with Nokia. So we're pretty excited about that relationship. Yeah, they rose to be more than a 10% customer. And we're really just, we feel getting started with Nokia, we feel there's a huge amount of potential there to continue to grow that relationship.
I appreciate all the colors. Thank you, Joe.
Operator
Thank you. Our next question comes from Tim Long with Barclays. Please proceed.
Thank you. Yeah, too, if I could, you're going to hit some of this again. And, Seamus, I know you don't want to talk too much about customers, but obviously NVIDIA is a reported one with 10% and pretty good decline in the year, understanding there's a lot of, you know, component issues that have plagued that business. Just curious of, you know, kind of current update on competitive landscape there, particularly as, you know, the newer programs that you guys tend to lead are a little bit more mature now. So just curious how I appreciate it's going to, you know, that business should overall go up a little up next quarter. But curious about the, you know, how you view the competitive landscape, particularly as, you know, some of the nodes have matured. And then I have a follow up after that.
Yeah, I mean, we're obviously not going to get into too much specifics on any one customer. But I will say that, you know, we're very pleased with our data center performance in Q4. and and we're optimistic that we've seen sequential growth in the first quarter both with uh long-standing customers like the one you mentioned and newer customers contributing to that growth um you know with respect to any any specific parts or components we don't want to speak on behalf of our customer or suppliers in these kind of three-way relationships especially for some of these high profile components but our supply chain team has been doing an excellent job managing these relationships and you know we have continued to get our share of the components we need. Demand, yeah, demand for certain components is higher than the available supply, and, you know, we're working very hard to mitigate that and make sure we get what we need.
And as always, you know, we have taken any potential gaps in supply into account in our guidance and, you know, expectations for growth in all three major revenue categories, including the data center business. okay um great and then you know maybe back to the hpc you mentioned some kind of newer opportunities there as well um i was wondering if you could just you know give us a little bit more color on types of products or in any color you can give us or or scale of what that could do to the business um it seems like you know got off to a pretty good start and the ramp has been pretty good through four quarters just curious what you know other programs could be added to that to keep that business growing.
Yeah, I mean, the products we're talking about are really follow-on products from previous generation products, and we've also won some additional products. You know, that relationship is going very well. It's well ahead of our expectations and on track to continue to grow for some time to come. You know, that's HPC is now included in our data center category. We won't be breaking out HPC as a separate category in future, but it is part of our data center category, along with, you know, the data comm products and also DCI and HPC, because those products are really what drives the data center revenue for us. But back to your question on HPC, you know, with AWS, the business is going very well. We're very happy with the relationship. We believe the customer are too, and we just continue to focus on doing a great job for them.
And that's the best way for us to win new businesses, to do an excellent job with the business that we have so that's our that's our focus okay thank you very much thank you too thank you our next question is from stephen fox with fox advisories hi thanks and good afternoon um famous i was wondering hi i was wondering if you could talk a little bit about uh the system integration business doing full systems with some of the um telecom networking oems and how that's going i believe you had talked about one major program and maybe there were others in the works but any update there would be appreciated and i have a follow-up yeah i mean we have we have a
number of um products that we make for our customers where we do the complete network system the sweet spot for us steven is where we do a lot of the component content maybe first and then work our way up through you know start off with components then do the let's say pcbas and then subsystems and sub assemblies all the way up to complete network systems so it's for us and for our customers it's very important that we have sufficient component content that we're making in order for it to be attractive for the customer and also you know sticky from our point of view that we're doing a lot for the customer more than just assembling systems so that's that's really been our focus that's how we've you know we've had some success with that with a number of our customers they probably the first foray into that business for us was with the the note the Infineira now Nokia business when when Infineira acquired Corrient several years ago we've also you know brought on significant Cisco completing that complete network system business and we're working on one or two others they take time they take a long time to come to fruition and and we usually start with the components and work our way up from there so we're working very diligently on that and you know we hope to have one or two to add in the coming quarters.
That's helpful. And then just on your comments about being able to improve revenue per square foot, it sounds like there's some interesting details. I don't know, maybe you want to share or don't, but beyond mix, can you give us an idea of how you're sort of getting more out the door than maybe we would have expected 90 days ago?
Well, I mean, if you look at the nature of the products and the business that's growing for us, DCI, of course, has been really good for us. And, you know, DCI products are generally physically small in form factor and revenue dense. So, you know, as we've shipped more, as we've been shipping more complex products to our customers, that revenue per square foot metric. And that's not to be all and end all. It's a function of better mix, but also improved efficiencies and better utilization of space. So there's a number of factors that go into it. It's not any one factor, but in a broad sense, it's a combination of more, you know, more complex products and therefore more revenue dense products and also better space utilization and efficiency improvements. We're pretty relentless about finding savings and finding, you know, better ways to utilize space and save on space because space is at a premium. So it's a combination of both.
Great. That's very helpful. Thank you.

Our next question comes from the line of Ryan Kuntz with Needham and Company. Please proceed.
Great, thanks. I want to ask about the telecom and DCI business, which continues to repair really, really strong numbers. Do you think you're seeing yet impact from scale across projects, number one? And number two, when do you think you'll see some impact from the new multi-rail amplifier densification? Is that a new market opportunity for you?
Thanks, Ryan. Yeah, we believe we are seeing both scale out and scale across in our business. Again, bear in mind our customers don't necessarily share with us their plans for where all of the products we make for them are going to end up. But we believe, yes, we are participating in both, you know, scale up, scale out and scale across. But specific to DCI, scale out and scale across. For the, you asked about the multi-rail product. You know, multi-rail architecture, they package and manage fiber pairs as a highly integrated optical system, creating really more photonics integration and manufacturing complexity per deployment. So they're quite complex and difficult. These platforms are highly manufacturing intensive. There's a lot of value-add and complexity that goes into producing these products. You have dense fiber routing and management, high-volume fusion splicing and connectorization and a whole array of precision optical manufacturing technologies and assembly processes that we're really very good at. We're actively engaged with customers on programs that leverage our strengths in these areas, especially in photonics integration and packaging. And we see multi-rail programs as a really good fit for us. They're right in our sweet spot. They're complex. They're difficult to make.
They require many process steps, which are, which these process steps are really our secret sauce. if you like so we're we're heavily engaged on a number of multi-rail programs with our customers again not really our place to announce them but rest assured we are heavily engaged with a number of customers on these uh these programs and we're we're very excited about them thanks Seamus and then maybe just a question on um your recasting of the the segment here when you say telecom is is kind of going to stay in communication infrastructure that's everything it's really rack-based should we think of it that way so it's line systems and rack-based transponders as opposed to you know dci which i assume is all all pluggables set that the split that we're
going to see here yeah hi ryan this is chava so let me let me clarify uh what is going into the communication infrastructure so i think the best way to think about it is is where our products or our customers products are being deployed so that's the number one distinction wherever we see A product that goes and ends up in a data center or a hyperscale infrastructure, we would categorize them under data center. And then the rest of the business that traditionally has been telecom, most of them would be network systems, but also some of the longer-term, long-reach products will be also falling into this category. So it's not a one-fit-all, but the number one thumb rule is that whenever the product's getting deployed, if it's a data center or hyperscale that goes in the data center, everything else goes into the communication infrastructure that is supporting that. Understood.
Thanks, Adam. Thanks, Rick.

Our next question comes from Carl Ackerman with BNP Parida.
Thank you. Hi, Seamus. On data content, have you seen higher interest from hyperscale customers seeking to diversify away from Chinese transceiver suppliers? And as you address that question, do you have the laser supply commitments needed to support the upcoming 1.6-hour transceiver ramp in the next few months? A little follow-up, please.
Yeah, I mean, the component supply, as I said in the earlier comments, it's factored into our guidance, so we're not going to go into specifics beyond that. You know, the proposed ban on new transceivers from China, i guess it's it's it's not yet a done deal it remains to be seen what will happen uh we don't manufacture for any chinese providers and are we're of course more focused on on western providers so you know in theory that could be a positive um as long as materials and components are available um it could be a positive should be a positive for us but i think it's early days uh like i said it's not a done deal and there's a lot there's a lot to be unpacked before that actually comes to fruition you know a lot of the transceivers that go into these data centers are coming from china so if you just put a put a you know a block on a ban on transceivers coming from china the whole industry goes to a halt besides whether it's good or bad for for fabernet so i think it's by no means a done deal and we'll see we'll see what happens yep well thank you for that within comms infrastructure, how are you thinking about the opportunity to address Leo's satellites today?
Could you discuss your visibility there relative to your earlier view this year?
Yeah, we include that in our telecom infrastructure category. We have a number of customers we're engaged with there, primarily the two, I would say, major players in that space, and there's one or two others we're looking to get into that space that we also do business with but uh you know for us it's a it's a really good fit because the technology is right in our sweet spot we have the customers today so as that business ramps we feel we're very well positioned to work you know we're making these products we've been making them for a number of years uh for one customer in particular in particular and now a couple of other customers so and they're again they're right in our sweet spot they're very straightforward if you like for us to make these products that really fit well with our capabilities so uh you know we feel good about our our position there we have the two big players and as i say there's one or two smaller
Operator
ones who we're we're also working with so we think it has a lot of potential for us thank you thank you our next question comes from the line of mike genovese with rosenblad securities uh so i'm all stepping in for Mike.
I was wondering if you can touch on the progress and mainly the timing for 1.6T driving revenue from your largest datacom customer.
Yeah, that's not something we're going to update the markets on on this call. This is a Fabernet call. You'd have to talk to NVIDIA about the NVIDIA product launches. So that's not something we would be disclosing to that level of detail.
Got it. Got it. Understood. And then just to follow up, just with the inventory jump, I'm assuming it's relative to supply constraints in the upcoming ramp. Is there anything else there, or is it mainly regarding that?
Well, I think the inventory jump has to do, obviously, with the revenue growth. So if you look at it from other perspectives, we are positioning material to continue to support our customers. The material constraints are something that we have been used to in the past several years, so those would not be a meaningful increase in our inventory.
So the inventory increase has to do with our growth growth and then the positioning for for future ramps for the customers got it thank you thank you one moment for our last question it comes from the line of teen salvage all with Northland capital markets hey good afternoon and congrats on congrats on the results and and also congrats on growing mid-30s with NVIDIA down 20% plus for the year. I think that's the rest of the business up nearly 60% on that basis. So that's quite impressive. Just a couple of quick questions. First on, as you look for Q127 guidance, I imagine data center is the primary driver, but within the three drivers that you mentioned, DCI, transceivers, high-performance compute, and noting that you had a really huge quarter with Cisco and DCI, and that was evident in their results. Can you kind of give us a sense of among those categories? I imagine it's transceivers that's going to drive the majority of the growth, but I'd love to get your – any color on that.
Well, really, first of all, thanks, Tim. I think you hit the nail on the head. You know, we finished, if you like, a 10-year spell from up to 2024, 17%. 100% compound annual growth, and then we had 19% compound annual growth in FY25, and then 36% in FY26 with 45% year-on-year growth in Q4. So we're pretty happy with the growth trajectory that we're on. Also, if you look at our performance over the last while, we had 12 consecutive quarters of record revenues and six consecutive quarters of accelerating year-over-year growth so it's it's been a you know we've been we've been on a very nice trajectory for the last while within the data center business and you know we think it makes sense to to categorize these particular products into into data center because you know DCI the transceivers of course are inside the data centers and then high performance compute is also an essentially data center product and DCI are between the data centers you know the growth in all three we think is is robust HPC continues to grow we won't be breaking breaking them out individually going forward but you know HPC continues to be very strong for us we're doing very well and we have a number of other customers that were focused on that are not in the revenue yet but we're working on the transceiver business a combination of our main customer but also success for getting with hyperscale direct and also merchant business that is just beginning to get going as well we feel very good about that and of course DCI you know DCI has been a real success story for us I think Chava did we say in our prepared remarks our run rate on DCI is about a billion dollars and to each other.
Yeah, so actually our DCI business reached a close to a billion dollar run rate. And if you look at our Q4 numbers, our DCI business was equivalent to our historical data com business. So that's a meaningful growth and continues to grow.
And if you look at each of those categories, I suppose especially DCI and the transceiver, the demand is just insatiable. It's extremely robust. and we're, you know, the demand is coming to us and coming at us from several directions. You know, our DCI, of course, we have really all the main players in DCI. The transceiver business, you know, historically we've had our main customer, but now we have these other growth factors to layer on top of that, both Merchant and Hyperscale Direct. And then Hyperform's compute just continues to go from strength to strength. So, you know, we feel very good, Tim, about our overall position in the data center business. And what's interesting is the customers are giving us visibility well out into, you know, the end of 2027 and beyond. That doesn't mean they're giving us firm orders, but they're giving us visibility. And there looks to be, you know, no end in sight to the demand from the customers. We feel very good about that.
Well, that is a perfect segue to my next question, which is you've mentioned accelerating growth. several times, including in response to that quick question, although I would note that the middle of the range might break your streak, but I imagine you're not heading for the middle of the range, still in the 40s in terms of year-over-year growth. But given that lengthy list of demand drivers and the capacity additions, is it within the bounds of reasonableness to think about annual growth in fiscal 27 accelerating from what you saw in 26, especially maybe given the lack of that headwind from your largest customer?
Yeah, I think that's a good point and a good question. I think, of course, you know, the standard answer, Tim, We guide one quarter at a time. However, based on the picture we have right now, it is not beyond the balance of possibility. And that's, you know, that's not something we would ever say, I suppose. We guide one quarter at a time, and we're going to continue to do that. But based on the demand we're seeing, certainly the demand is there, you know, that we could see another year of accelerating growth. It's just a staggering demand picture we're seeing from our customers. And the, you know, the thing that's particularly satisfying for us is the trust that the customers are placing. And it's obviously the revenue is great. Don't get me wrong. But it's really the trust the customers are placing. They're, you know, they're trusting us with their most important products, their leading edge products. And we're, you know, we're on a ramp with several of these customers. That is just amazing. So, yeah, I think it's not beyond the bounds of possibility to answer your question.
Great. And let me close by adding maybe one other growth driver that I don't know that's been discussed that yet, and that's Optical Cross Connect OCS. And, you know, we heard last week, you know, big ramp there from the industry leader, but also, you know, I think plans to move from strictly internal to working with contract manufacturers.
I wonder if you might be able to give us an update on, you know, what you think the timing might be there for you or the opportunity and does that lie in fiscal 27 as well yeah I mean you know obviously OCS is a it remains a great opportunity for us it's it's right in our wheelhouse it's it's you know the manufacturing technologies is very similar to products that we're already making for for for our customers so we already feel like we have a bit of a head start so no real change in our optimism on OCS You know, but there are incremental opportunities for us in that, you know, for us, OCS is quite small today. We are shipping some product, but it's quite small. So I think the big ramp that maybe has been talked about, we're pretty confident we will participate in that. So we feel very good about OCS, and I think it could be a bigger, much bigger and more meaningful category for us in the future. The specifics of our customers' ramp, we leave that to them to talk about, but I think we're well positioned.
Operator
Thank you. And this will conclude our Q&A session for today. I will pass it back to Seamus Grady for closing.
Thank you. Thank you for joining our call today. and we, you know, we delivered an outstanding performance in Q4 with continued top line acceleration that ended a tremendous year for the company. We are entering fiscal 2027 better positioned than at any other point in our history to continue delivering strong growth in response to the increase in demand that we are experiencing across our business. With our deep domain expertise and increasing capacity, we expect to extend our manufacturing leadership as a trusted partner for our customers' most complex products. We look forward to sharing more excellent results with you in the future and to seeing those of you who will be attending the Rosenblatt Conference tomorrow and the Wolf Conference in September. Thanks again and goodbye.
