We will begin the call with remarks from Seamus and Chava, followed by time for questions. I would now like to turn the call over to Fabernet's CEO, Seamus Grady. Seamus?

Thank you, Gerald. Good afternoon and thanks to those joining our call today. we had an excellent fourth quarter ending an outstanding year with tremendous momentum fourth quarter revenue was 910 million dollars which was above our guidance range and up more than 20 percent from a year ago and four percent from q3 with margins that were a little better than expected we also achieved record non-gap earnings of two dollars and 65 cents per share For the full year fiscal 2025, revenue reached a record $3.4 billion, representing a robust 19% increase over the prior year. Non-GAAP EPS also hit an all-time high at $10.17. Looking back, fiscal year 2025 was an exceptional year of execution and growth for Fabernet. We navigated a significant product transition at a major Datacom customer, while our telecom business and overall revenue reached record highs. We established a significant partnership with Amazon Web Services, which we anticipate will be a meaningful revenue driver in fiscal year 2026. Construction began on Building 10, which will add 2 million square feet of capacity to our overall footprint. We also marked the 15th anniversary of our IPO by ringing the opening bell at the New York Stock Exchange. Additionally, we returned $126 million to shareholders through our buyback program, with continued repurchases expected in fiscal 2026. We begin fiscal 2026 with strong, broad-based momentum. Robust customer demand across our business leaves us better positioned than ever to capitalize on the many significant opportunities ahead of us. In fact, with multiple growth drivers providing clear visibility toward reaching $1 billion in quarterly revenue, we are now evaluating options to accelerate the completion of a portion of Building 10 to meet increasing customer demand. Looking more closely at our fourth quarter results, optical communications revenue delivered strong growth. Telecom revenue increased 46% from a year ago and 1% from Q3, with system programs and demand for data center interconnect products driving the bulk of our growth. In fact, DCI revenue represented one quarter of our total telecom revenue and grew 45% from a year ago. We expect our telecom momentum to continue into Q1, especially as we begin to ramp volume production of a next generation system program for a major customer. As anticipated, datacom revenue was down from a year ago, but increased double digits sequentially as we enter a meaningful growth phase for 1.6T products. With demand still increasing, we are very optimistic about datacom growth trends for fiscal 2026. In the near term, this surge in demand has created some temporary component supply challenges, which we are working closely with a major customer to overcome. Within non-optical communications, automotive performed better than expected for the quarter, with only a slight sequential decline, while industrial laser revenue remained stable. Looking ahead, multiple simultaneous growth drivers give us strong optimism for fiscal 2026 these include the launch of a new telecom system continued growth in dci increasing demand for 1.6 t transceivers and the ramp of a prominent high performance compute program we remain confident in our ability to maintain excellent execution while continuing to grow both revenue and earnings in summary we are pleased with our outstanding performance in q4 and throughout fiscal 2025, more importantly, we enter fiscal 2026 in a very strong position, reinforcing our optimism for the future as we further solidify our leadership position in the marketplace. We look forward to carrying this momentum into a strong Q1. I'll now turn the call over to Chaba for more financial details on our fourth quarter results and our outlook for the first quarter of fiscal 2026. Csaba.

Thank you, Seamus, and good afternoon, everyone. We had a very strong fourth quarter, achieving new quarterly records for both revenue and non-GAAP net income. Revenue in the fourth quarter was $910 million, above our guidance range, and an increase of 21% from a year ago and 4% from Q3. Non-GAAP EPS was $2.65, a new quarterly record. This result includes the impact of a $4 million or $0.10 per share FX evaluation loss. Looking at revenue performance by category, in the fourth quarter, optical communications revenue was $689 million, up 15% from a year ago and 5% from Q3. within optical communications telecom revenue reached a robust 412 million dollars up 46 from a year ago and one percent from q3 this performance reflects growing demand driven primarily by continuous trend in data center interconnect products for the first time we are reporting dci revenue which reached 107 million dollars in the fourth quarter representing 12 percent of overall revenue to provide investors better insight into this important growth area we have included historical dci revenue data in the investor presentation available on our website datacom revenue of 277 million dollars was down 12 percent from a year ago but swung to a strong growth of 10 sequentially driven by very strong demand for new higher data rate products in optical communications revenue from 800 gig and faster product for 313 million dollars up 21 year over year and 32 sequentially driven primarily by the ramp of new 1.60 datacom products importantly we have now begun volume shipments of 1.60 transceivers a major milestone and expect demand trends to continue ramping in fiscal 2026. In contrast, revenue from products below 800 gig was $233 million, up 4% from a year ago, but down 18% from Q3, reflecting the industry's transition to next-generation products. Revenue from optical communications products that are non-speed rated was $143 million, up 4% from Q3. we expect strong revenue momentum from 800 gig and faster products to continue while revenue from lower speed products is expected to decline gradually as the industry transitions towards higher data rates as a result beginning next quarter we will no longer report revenue by data rate similarly starting in q1 we will discontinue the breakout of silicon photonics revenue as the vast majority of it is now captured under dci Non-optical communications revenue was $221 million, representing a healthy 41% increase year-over-year and 3% sequential gain. Automotive revenue came in better than expected at $128 million, experiencing a modest quarterly decline following several quarters of rapid growth. Industrial laser revenue was stable at $40 million. Other revenue was $53 million, up 38% year-over-year, and 20% from Q3, with the sequential increase primarily reflecting the absence of a non-cash contra revenue item recorded in Q3. As I discuss the details of our P&L, expense and profitability metrics will be on a non-cap basis, unless otherwise noted. Gross margin in the fourth quarter was better than anticipated, at 12.5%, with operational efficiencies offsetting a smaller-than-expected impact from large project ramps. Operating expenses remained below 2% of revenue, resulting in record operating income of $97 million, or an operating margin of 10.7%, a 50 basis point improvement from Q3. interest income was $8 million in Q4. As I mentioned, we also incurred a foreign exchange evaluation loss of $4 million. Effective gap tax rate was 6.5%. Non-gap net income was $96 million or $2.65 per diluted share. For the full fiscal year, revenue was a record $3.4 billion, dollars, up 19 percent from fiscal 2024. Non-GAAP EPS was 10 dollars and 17 cents for the year, which includes the impact of an 11 cents headwind from non-cash contra revenue and a 26 cents impact from FX evaluation losses. Looking at customer concentration, in fiscal 2025 we had two customers who represented more than 10 percent of our total revenue, with NVIDIA at 28% and Cisco at 18% of revenue. Our top 10 customers made up 86% of total revenue for the year, consistent with last year. Turning to our balance sheet highlights, we ended the year with cash and short-term investments of $934 million, down $16 million from the end of Q3. operating cash flow in the quarter was 55 million dollars capital expenditures rose to 50 million dollars primarily driven by building 10 construction costs and investments to support new program ramps resulting in fourth quarter free cash flow of 5 million dollars as Seamus mentioned we are actively evaluating options to accelerate the construction of building 10 in response to growing customer demand. If we move forward, quarterly capital expenditures could temporarily increase from current levels. With our very strong balance sheet, we believe we have ample cash to support our top capital allocation priorities, which are first, investing in our future growth, and second, returning value to shareholders through our buyback programs. In the fourth quarter, we remained active in our share repurchase program. We repurchased 108,000 shares at an average price of $206 per share for a total cash outlay of $22 billion. For fiscal year 2025, we repurchased 126 million worth of Fabernet shares, which is the most we have ever spent on repurchases in a single fiscal year.

We entered fiscal 2026 with $174 million available for repurchases.

Now, turning to our guidance for the first quarter of fiscal year 2026, we remain very well positioned to extend our track record of excellent growth and execution. In DALACOM, we expect our very strong revenue growth trends to extend into the first fiscal quarter, driven particularly by ramping system programs. In DALACOM, we are excited to see growing demand, especially for next-generation products. however the surging demand has resulted in near-term supply constraints for some critical components and as a result we expect to see a sequential dip in datacom revenue in q1 we are working with our customers and suppliers to resolve these supply issues which we expect to be temporary in non-optical communications we anticipate strong growth driven primarily by a a new high-performance computing program. Since this new revenue stream does not align with our current disclosure categories, beginning in Q1, we will be introducing a new revenue category called HPC. In automotive, we expect the near-term softness experienced in Q4 to continue into Q1, but we remain optimistic about a return to more normalized growth trends. Industrial laser revenue should be relatively flat. Taking all of this together, we anticipate healthy year-over-year and sequential growth in the first quarter, with total revenue in the range of $910 to $950 million. From profitability perspective, please keep in mind that our annual merit increases take effect in Q1, creating seasonal margin pressure of about 10 to 20 basis points that we typically recover through efficiency gains over the course of the year. In addition, Q1 margins will be impacted by temporary inefficiencies from new product ramps, which are expected to subside as these programs advance through their early production stages. With that in mind, we remain optimistic that we can achieve gross margins within our mid-12% target range while continuing to generate operating leverage that supports steady improvement in operating margins over time. We expect earnings per diluted share to be between $2.75 and $2.90. In summary, this is an exciting time at Fabernet. We delivered a very strong fourth quarter and an outstanding fiscal year.

Operator

With multiple new programs fueling our long-term growth trajectory and our strong competitive position, we are highly optimistic about Q1 and the new fiscal year ahead. operator we are now ready to open the call for questions as a reminder to ask a question you will need to press star one one on your telephone to remove yourself from the queue you may press star one one again please limit yourself to one question and one follow-up to allow everyone the opportunity to participate please stand by while we compile the q a roster our first question It comes from the line of Carl Ackerman of BNP Paribus. Please go ahead, Carl.

Garo Toomajanian Head of Investor Relations

Yes, thank you, gentlemen. Congrats on the quarter. I have a clarification question or a follow-up, if I may. The clarification question is the dip in Datacom revenue that you expect in September, does that exclude or include contributions from the new HPC segment?

Hi, Carl. Thanks for the question. So the new HPC program is not in our Datacom number in Q1. It will be in a new category that we'll report in the quarter called HPC or High Performance Compute. So HPC will not be in Datacom. It will be in its own category. In Q4, it was in Other as it just got off the ground. But in Q1, it will be in its own category.

Garo Toomajanian Head of Investor Relations

Got it. Thank you for that. So, Seamus, you've suggested in the past that hyperscalers are interested and certainly have the opportunity to, you know, perhaps have an EMS partner manufacture transceivers.

I know you've been shifting manufacturing capacity away from 800 gig toward 1.6 T. So should we assume that any future hyperscaler transceiver opportunities would be on 1.6 terabit port speeds, or do you still see a very long runway of growth on 800 gig? um no i think what it depends on really whether we're talking about our main customer or the market generally for our main customer it will be predominantly 1.6 g but for you know for the datacom customers generally it will be both 800 and 1.6 we don't see much uh going on below 800 gig for you know the the datacom opportunities if you like in total that we're pursuing uh you know we usually work with our customers on the current plus the next two generations of products and so in addition to our leading datacom customer we have other long-standing datacom customers that we're working with who are designing their own products for 800 gig 1.6 and also cpo products we're also pursuing engagements with a number of merchant transceiver suppliers as well as as you mentioned uh hyperscale direct so we have four if you like four distinct growth vectors in the datacom space our largest datacom customer other datacom customers who are designing their own products merchant transceiver manufacturers and uh and hyperscalers direct and we're actively pursuing all four of those growth vectors very good thank you So you're welcome.

Thank you. Our next question comes from the line of Tim Savageau of Northland Capital Markets. Please go ahead, Tim.

Tim Savageaux Analyst — Northland Capital Markets

Hi, good afternoon, and congrats on the results. It's a higher-level question, perhaps. I think maybe it was the close of last quarter's call. James, you talked about, I guess, the potential for accelerating growth in fiscal 26 off of what was a pretty strong 25, growing 19%. I guess the question is, any more precision on that now that we're three months later? Do you still feel like that's the case? Does perhaps the component issues change that?

Or would you just love to get your view on that previous statement? yeah i think we you know we enter fiscal year 26 very optimistic about the year ahead uh as you say we had a we had an excellent fy25 you know we grew 19 and we grew 19 in the year where our largest customer our business with our largest customer was was down on a on a dollar for dollar basis um so that you know we we feel i would say very optimistic tim about the year ahead We guide one quarter at a time, so we're not going to give full year guidance, but I think our cause for optimism remains. You know, the datacom business is coming back and the demand is outstripping supply right now. That's a temporary issue, but we have very strong demand for 1.6 terabit products right now. We have a number of other datacom products in the works, as I just mentioned. the strong telecom trends continue driven primarily by by DCI and you know we have we have a number of new customer wins of course that we've that we've talked about previously but overall I think we we enter the year you know with a very positive outlook for the year ahead and I guess that's evident to some degree in your comments about maybe accelerating the building 10 capacity the expansion and trying to figure out exactly what you're trying to communicate here.

Garo Toomajanian Head of Investor Relations

Have you pulled the trigger on something?

Tim Savageaux Analyst — Northland Capital Markets

Are you very close to, or how, as you said, evaluating options, how might we see that move forward and over what time frame?

Yeah, so the decision to pull Building 10 in to get a portion of the building completed, maybe one or two quarters ahead of the original schedule, we're really communicating that because it will impact our capex obviously we'll have to spend a little bit more to pull in completion of a portion of the building and it's a combination of a few things it's a combination of the you know the the business opportunities that we just talked about that we're addressing right now in telecom data com and high performance compute as well as some other potential new opportunities we really want to be able to occupy some of the space in building 10 before the total building is completed so you know meanwhile we have flexibility we can accommodate all the demand that we're seeing but we do want to be able to occupy you know a few hundred thousand square feet of building 10 probably three to six months ahead of originally contemplated great and last one for me wonder if you can talk about whether your new telecom systems when contributed in a material way in Q4 it contributed to me we're really just getting going you know we've we've always said this when it will ramp in FY 26 so we're just really getting started with that and it will ramp as we go throughout the year so it did contribute but you know it's really as we go through the year that we start to see that program ramp but it's going very well we're you know we're very happy with the relationship i think the customer is happy and we're we're very you know very happy with how it's going and how the ramp the ramp schedule is going but but the big i would say that the bulk of that ramp is still in front of us thanks very much thank you jim thank you our next question comes from the line of samik Chatterjee of JPMorgan.

Please go ahead, Samit.

Joe Cardoso Analyst — JPMorgan

Hey, guys. Thanks for the questions. This is Joe Cardoso on for SOMIC. Maybe for my first one, you know, in a similar vein to the prior question on kind of the growth prospects for the company kind of heading into next year, you know, just given these multiple customer ramps across various and different products, some of them being kind of newer to the portfolio, anything we should keep in mind relative to kind of the gross margin and OPEX trends going forward, anything one-off or different from kind of what we're used to in terms of the historical profile for Fabernet, just trying to be mindful that there's a lot of irons, you know, in the fire here. And so if there's anything that we should be kind of considering, and then I have a follow-up.

Hi, Joe, this is Chavez. Let me take that question. With regards to profitability, obviously our aim is to maintain our gross margin target range in the mid 12 percent so obviously as you would anticipate some of these large new programs would put some temporary pressure on the gross margins however we do anticipate that this headwinds to be temporary and subside over time we did call out a small headwind in our q1 guide because that's a seasonal quarter for us with merit increases as well as as this program ramps are coming through. However, we don't anticipate any structural changes in our portfolio or margin profile. So our aim is to maintain our existing gross margin range.

Joe Cardoso Analyst — JPMorgan

And then just on the OPEX side, and then I have a follow-up.

OPEX, we have been very careful about spending on operating expenses, and we have been very cautious about adding costs, and we will maintain that discipline. As you see, our track record, we have been able to deliver operating leverage year over year, so we continue that path. We don't anticipate to add any significant OPEX other than the usual merit increases throughout the year. So that should continue to drive operating leverage as the top line grows.

Joe Cardoso Analyst — JPMorgan

Very clear. And then maybe just as my follow-up, 800 gig trends, you mentioned 1.6 being kind of the primary driver of growth sequentially, but curious how much of a gating factor was the supply constraints that you highlighted? And as you think about the ramp going forward, any color on how you're thinking about the magnitude of the impact from these bottlenecks and when we potentially could see them easing and then maybe just quickly, like any color of whether that's what components those are, lasers, DSPs, anything else that you guys are seeing, that's kind of the concentration of the supply constraints.

Yeah. So it's, you know, really it's an it's a handful of components that are that are causing us to have some component constraints you know with with the as we saw this past quarter and into this quarter and beyond we think now it's surge in demand for 1.6 T transceivers and a particular you know 200 gig per lane EML based products we are seeing some supply constraints and before for for specific components it's a small number of components it's not broad based it's unique to really one component for for one or two components for one product for our customer or for one customer and because of these constraints we're anticipating that the data from revenue will be done we've called that out in our prepared remarks but we think it's short-lived we we're pretty confident we're pursuing multiple paths with our customer and with the supply base to help remedy the constraints in order to meet the strong demand and we believe the supply issues will be temporary but they will take a little bit of time to fully resolve maybe you know one or two quarters but we do think it's a it's a it's a shortly of problem but it's one we have to deal with right now the good news is the demand is very strong and you know the current demand is strong and well above the supply availability but like I say it's not unusual when you get a new product like this a kind of a leading-edge product with leading-edge technology and a big spike couple with the big spike in demand that's not unusual to have these temporary supply constraints, but we'll work through that.

Joe Cardoso Analyst — JPMorgan

Thank you, gentlemen. Thank you, Joe. Thank you.

Our next question comes from the line of Stephen Fox of Fox Advisors. Please go ahead, Stephen.

Stephen Fox Analyst — Fox Advisors LLC

Hi. Good afternoon. I think I'm still a little confused on the gross margins. Can we back up and just talk about the fiscal fourth quarter margins for a second? You did better than you thought you would on efficiencies, but I would assume you had some of the product ramps going on. I guess you avoided the component shortages in the quarter and weren't expanding on building 10 yet faster than previously thought. If you could just break that down, why didn't you see some of these headwinds and how else you got efficiencies in Q4 besides better sales?

I know that's a follow-up. So let me clarify.

So first of all, Steve, building 10 expenses are not in the numbers. So building 10 is a future event. So we don't see any growth margin headwinds from building 10 context. So that's number one. Secondly, obviously, as these programs are ramping, obviously, we do have certain inefficiencies that are baked in our outlook. However, the existing business continues to execute very well, and we have a very strong execution. So that's, on the flip side, that resulted in a better-than-expected gross margin in our Q4. and we do anticipate that this product ramps will put some pressure on the near-term gross margin so going into Q1 we expect a mild headwinds but Q4 was strong and it's not particularly because of building 10 it's just a very strong execution on the on the legacy business and obviously starting off with the new programs.

Just if I can just add maybe to Chavez comments there Stephen you know the ramp costs that we we had assumed going into the quarter we came in a little bit better than we had planned but you know we have we have a few quarters I think now of uh fairly strong ramps going on simultaneously so we are going to have to carry these ramp costs you know when we when we start a new programs some of these big programs takes a little bit of time to get ramped up to full efficiency so we we do carry some startup costs or npi costs when we start these programs and then you know in q4 we just did a little bit better on on efficiencies our operations team did an excellent job outstanding uh sorry an excellent job to to execute uh to make sure that we came in a little bit a little bit better than anticipated uh in q4 and just uh one other minor detail and all that and that's very helpful is that you didn't experience any component constraints to speak of in q4 is that correct not not any huge constraints i mean we we have again as we called out there a couple of constraints going into uh into q1 there was there was some in q4 but the the big hit really is in q1 um you know we we were able to get what we needed in q in q4 uh but we are we are constrained in q1 yes typically steven typically we don't have margin impacts from component shortages so we are always able to juggle the

Stephen Fox Analyst — Fox Advisors LLC

capacity to make sure that component constraints don't don't create near term and good thing about component constraints we we have a fairly good visibility on on supply so we are able to adjust capacity so there is no concern of headwinds from component constraints when it comes to gross margins great uh thanks for explaining all that and then just as a follow-up can you a little bit more on the data center interconnect business um i thought you also had talked about some new customers for the new fiscal year i know you don't you only got a quarter at a time but can you give us a sense for the momentum you were up 45 year over year in the quarter any way to think about how you know the momentum directionally continues for the rest for the new fiscal year

anything any other clues you can provide there thanks yeah maybe i'll let chava put a bit more detail around the button you know in general steven our dci business has been very strong uh we've we've captured a number of customers there uh they're all ramping and we're able to keep up with the demand and the demand seems to be you know it's strong it's robust and it looks to be durable and it is it is increasing over time so i think as these these big data center uh you know clusters get rolled out these these big ai workloads get shared around between data centers, the need for DCI is increasing, if anything. So we see DCI demand continue to be very strong for some time to come.

And some clarification there, Steve, as well. So DCI is a distinct category, as you called out. We wanted to give that additional color to the investors. So it's part of our telecom business, but we wanted to call out as it's a significant growth driver as we look ahead. So there is one more thing that's going on in DCI. Obviously, The bulk of that growth came in the fiscal year from 400 ZRMs. We started to see transition to 800 ZR as well, but it's not at the expense of 400 at this stage. So there is that growth driver going on there. And to clarify your question about the new programs, we did not talk about particular DCI programs as a new category going forward. So DCI, we have already captured the customers who we have been shipping, and we anticipate the growth to come from those customers. So the new system will be in the telecom space, not the DCI, and the HPC is going to be a distinct its own segment and another DCI category.

Stephen Fox Analyst — Fox Advisors LLC

Great. That's all super helpful. Thank you very much. Thank you, Steve.

Thank you.

George Nader Analyst — Wolfe Research

Our next question comes from the line of George Nader of Wolf Research. your question please George hi guys thanks very much can you just remind us the triggers on on vesting of the Amazon warrants and recognition of Contra revenue I know that it was four million last quarter I think none here in the June quarter can I assume that you did not generate revenue with Amazon this quarter is that the right read-through so George so basically the first last Westing was prior to signing the contract.

So upon signing the contract, we invested 10% in Q3. So that was one condition of the Westing. The rest of the shares will invest over revenue and over time. So the fact that you haven't seen anything in Q4 has to do with the fact that there is a threshold that to be met in terms of revenue shipments. So it doesn't mean that we haven't shipped anything. But future investing will be subject to revenue and volume shippants throughout the year.

George Nader Analyst — Wolfe Research

Got it. And then any – I guess we're all curious about how big that Amazon PCB business can be over time. I mean, obviously you're breaking it out into its own category. I get that certainly. But, you know, is this hundreds of millions of opportunities? Is this in the billions? Like, how do you kind of think about the scale of what you can do here?

Yeah, so, you know, as we look at the opportunity, it's certainly a significant opportunity for us. You know, it could be significant. We believe it could be significant this fiscal year. We're not sizing the overall revenue with the customer there or the high-performance compute deal. we have with them but the business will start to ramp in q1 uh we you know we did ship a little bit in q4 but it will start to ramp in q1 and that is contributing to our strong you know anticipated sequential growth um but keep in mind that our shipping uh i'm sorry yeah so yeah i'm sorry calendar yeah calendar q1 is just the beginning for us though with uh with aws and we think there be more more to come we have we have you know one opportunity there's a high performance compute opportunity but we're working hard to see if we can you know again some momentum in other other categories there um longer term high performance compute we think represents a significant new time expansion opportunity for us and that's why we've we've decided to to classify it as its own category so we were again we'll be disclosing in our q1 we'll be disclosing HPC as its own category. We'll also be disclosing, as Trevor mentioned, or be starting to disclose DCI as its own category.

George Nader Analyst — Wolfe Research

Got it. And then, I'm sorry, just to be clear, the ramp is in your fiscal Q1 or in calendar Q1 of 26?

Fiscal Q1. We've already started. We've already started. We've shipped some revenue in Q4. And really, that's just the getting off the ground. And that's why we have the, if you like, we've called that the startup up costs because you know as you can imagine when you start up you don't start it at uh cruising speed we we start up we get the lines debugged we get the efficiencies up we make sure the yields are good you know the customer comes and qualifies the production line and then we start ramping so that work has been largely completed now and we're just beginning to ramp properly then this quarter So fiscal Q1.

George Nader Analyst — Wolfe Research

Thank you.

Thank you. Thank you, George.

Thank you. Our next question comes from the line of Ryan Kuntz of Needham & Company. Please go ahead, Ryan.

Ryan Kuntz Analyst — Needham & Company

Super, thanks. I'd ask also about Datacom, maybe a different angle here if we could. I certainly understand the ramp going on for your large customer at 1.6 T. That's self-evident. You've talked about, I think, 800 remaining strong. And obviously, there are other customers involved in the mix there. But Seamus, how would you characterize your visibility for 800 demand right now as you look at this next fiscal year? I think there's been some investor concern that that might dry up with your large customer shifting over.

Our visibility is quite good. I mean our main focus is is on the next generation products the 1.6 T but but we have visibility on 800 gig as well our visibility is quite good and like I say in both both areas it's it's supply constrained as opposed to our demand constrained right now right and then you guys had some pretty decent auto numbers out of segment any any view of how you think that unravels in 26 I I think, you know, steady. We think steady. I don't think it's going to have the same kind of growth trajectory as, let's say, high performance compute or datacom or even telecom. It's probably telecom. It's probably more steady, steady growth as we as we gain market share. Again, bear in mind, our automotive business is more on the infrastructure side, the EV charging side of the business. So we're not as exposed to consumer sentiment as maybe other companies who are producing for automotive companies. So we think automotive will be steady, but maybe not grow quite as fast as Datacom or Telecom or the others.

Sneaking in around tariffs, any dialogue with tariffs?

Yeah, it's an interesting one. you know for us we haven't seen any meaningful impact to date from the tariffs you know first bear in mind our shipping terms with our customers dictate that the receiver or the customer is responsible for the tariff so we don't bear the cost of the tariffs and the products we make both in the optical communication space and the non-optical communication space those categories are not necessarily shipped directly to the U.S. as they may be shipped to you know Asia or Europe or elsewhere to another contract manufacturer for higher level assembly so in many cases the products we make they don't ship directly into the U.S. so thus far we have not seen any any significant impact from tariffs thankfully.

Thank you. Our next question comes from the line of Mike Genovese of Rosenblatt Securities. Please go ahead, Mike.

Garo Toomajanian Head of Investor Relations

Thank you. Seamus, I'm wondering, do you have any of your 800G customers moving to 200G per lane lasers, or is 800G still a 100G per lane market? it?

The focus for us is on 200 gig per lane, 800 gig products. That's where the bulk of the bulk of your screen is on 200 gig per lane, 800 gig products.

Garo Toomajanian Head of Investor Relations

So when you talk about supply constraints then, is it in both, for the current quarter, is it in both 800G and 1.6, or is it more in 1.6 than in 800?

It's affecting both. It's both 800 gig and 1.6 T, yes.

Garo Toomajanian Head of Investor Relations

So then when we talk about being sequentially down in the quarter, then that sounds like it could happen at more than one customer. That would be something that would happen at multiple customers because potentially 200G per lane EMLs are in short supply. Is that a right read?

Yes and no. I think there's a number of opportunities we're working on with customers, but they're not producing meaningful revenue in the current quarter. We're working on several opportunities. The big impact is with our main customer on the 200 gig per lane, again, which impacts both 800 gig and 1.6. But there are other customers we're working with on both 800 gig and 1.6, actually, but they're not meaningful in terms of revenue in the current quarter.

Okay, perfect. I'll pass it on. Thank you.

Thank you, Mike.

Thank you. Once again, to ask a question, please press star 11 on your telephone. Again, that's star 11 to ask a question. It's coming from Tim Savageau of Northland Capital Markets. Please go ahead, Tim.

Tim Savageaux Analyst — Northland Capital Markets

Yeah, thanks for the follow-up, and just a couple quick ones. One, you know, could you take a shot at quantifying the impact of the component shortages on Datacom? I assume without that, they'd be up. Would that be up significantly? You know, throw us a number on that one. And also, obviously, 800 gig and above grew quite sharply in the quarter, but much more sharply in – not as sharply as Datacom. Sorry, Datacom didn't grow that sharply. So it looks like you had a big kick up at 800 gigs and above telecom. And that was kind of what I was asking with Sienna before. But if I'm reading the numbers right, I wonder what might be driving that.

Yeah, I think on the, you know, the impact of the component shortage in datacom, we're not going to quantify that, Tim. But it's, you know, I put it this way, it's meaningful enough for us to call it out. You know, we would be up fairly significantly were it not for that issue. um you know we're not going to quantify it but it's a it's a it's a substantial enough um headwind for us this quarter on the 800 gig and above yeah that's a mix of as you rightly point out both datacom and telecom so you know good growth in in the datacom business the 800 gig and above but also uh you know primarily dci and other products in the in the 800 gig telecom category on the job if you want to add anything to that no i think that's the color we can provide in there so obviously we are seeing some uh in dci we have it's below 800 gig team so 400 zr was very strong

in dci segments so that potentially that's called a reason for not going as fast as as data thank you jim thank you i would now like to turn the conference back to seamus grady for closing remarks.

Thank you for joining our call today. We're very pleased with our strong fourth quarter results culminating in another record year for the company. As we look to the first quarter and fiscal 2026, we're very excited about the opportunities that lie ahead and believe we're better positioned than ever to extend our strong track record of growth and execution. We look forward to speaking with you in the future and to seeing those of you who will be attending the Wolf Research Conference in September. Goodbye.
