Thank you, Hong. For Q4, we recorded net sales of $251 million, up 6% sequentially. Net sales trends by end market, reportable segment, and geographic region are included on slide 16 of the earnings presentation.
Adjusted gross margin was 53.2%, up 80 basis points sequentially and of 430 basis points year over year. Adjusted net operating expenses were $83.7 million, within our guidance range, with a sequential increase in research and development for what we believe to be prudent investments to accelerate realization of market opportunities.
Adjusted operating income was $49.8 million, resulting in an adjusted operating margin of 19.9%, up 160 basis points sequentially, and up 1,070 basis points year over year. Adjusted EBITDA was $57.8 million. And adjusted EBITDA margin was 23%, up 140 basis points sequentially and up 1,050 basis points year over year.
Adjusted gross margin, adjusted operating margin, and adjusted EBITDA margin all sequentially improved in each quarter of FY25, representing sustained growth. Adjusted net interest expense was $11.2 million reflective of approximately two months of savings from a debt pay down. We recorded adjusted diluted earnings per share of $0.40, up from $0.26 in Q3, and up from a loss of $0.06 from Q4 of last year.
Operating and free cash flow for Q4 were $33.5 million and $30.9 million, respectively. We ended Q4 with a cash and cash equivalent balance of $151.7 million, which included principal payments of $10 million on a credit facility that were incremental to payments from the equity offering.
At the end of FY25, net debt was $411 million, a reduction of $868 million, or 68%, from the $1.3 billion as of the end of FY24. I believe we executed well to our previously stated capital allocation priority of reducing leverage.
To summarize benefits Semtech has and expects to realize from debt reduction: first, debt paydown enables Semtech to focus investment on our core business growth engines; second, the reduction in debt from the equity offering will provide annual cash savings of approximately [$48 million] based on interest rates at the close of the offering, which resulted in accretion on a non-GAAP basis; third, we believe meaningful debt reduction demonstrates a strong commitment to our customers, suppliers, and partners to improve financial solidity and return focus to operational and strategic priorities which we expect will lead to increased collaboration and market share gain.
Now turning to our first-quarter outlook. We currently expect net sales of $250 million, plus or minus $5 million, up 21% year over year at the midpoint. We expect net sales from the infrastructure end market to increase sequentially with data center applications leading to growth. This outlook incorporates the effect from CopperEdge related to previously discussed rack architecture changes.
We expect net sales from the high-end consumer end market to be up slightly, reflective of a seasonally stronger first quarter. We expect the industrial end market to be down, reflective of seasonality in our IoT portfolio.
Based on expected product mix and net sales levels, adjusted gross margin is expected to be 53%, plus or minus 50 basis points. Adjusted net operating expenses are expected to be $87 million, plus or minus $1 million, resulting in an adjusted operating margin at the midpoint of 18.2%, a 600-basis-point improvement year over year.
Adjusted EBITDA is expected to be $53.3 million, plus or minus $3 million, resulting in an adjusted EBITDA margin at the midpoint of 21.3%, which would equate to a year-over-year increase of 520 basis points. We expect adjusted net interest expense to be $6.3 million, reflective of leverage-based pricing on our credit facility that reduces our term loan interest rate by 200 basis points. We expect a normalized income tax rate of 15% consistent with our FY25 rate.
These amounts are expected to result in adjusted diluted earnings per share of $0.37, plus or minus $0.03, based on a weighted average share account of 90.1 million shares.
With that, I now would like to turn the call back over to the operator for Q&A.

Question and Answer Session

Operator

(Operator Instructions) Harsh Kumar, Piper Sandler.

Harsh Kumar

Yeah, Hong and and Mark, you guys have done a great job on the balance sheet. But you actually said something on the CopperEdge portfolio that caught my attention given the controversy around it. Hong, I was hoping that you could expand on your comment around what you're seeing in boards and connectors. And also, you mentioned your sort of lead customer is looking at components of these products and this technology for future generation. Maybe also explain on that.
And then sorry for the multi-part question. You said you expect to be down or lower for a couple of quarters. I think you said 3 or 4, but then you expect to pick up. So maybe talk about all this and why you expect to pick up and what content are you seeing in in these places, particularly with your large customer.

Hong Hou

Thank you, Harsh, for the questions. So first of all, just on the CopperEdge. In Q3, we reported our revenue is a high-single-digit million dollars and we guided in our Q4 to be marginable, incrementally increased. We just did that. And so we've announced that previously in FY26, the revenue for CopperEdge is going to be below $50 million.
So as we reported on the data center revenue on Q4 is a $50 million. CopperEdge portfolio added into a very broad data center portfolio is a nice addition. So in the future, we do not intend to break out a CopperEdge contribution to the total revenue of the data center portfolio. But as for the engagement, as I reported, we have been engaging with over 20 customers.
This is a nascent business. It's a new product. It's generating a lot of interest. And it was only released about a year ago, but it will take some time for our customers to design them in in a different form factors.
So the revenues to date have been primarily generated from the applications in the active copper cables, but we have many use cases for different applications by different customers designing our CopperEdge product onto the board or in the connectors. So we do see that a different pace of the adoption and a qualification and testing status, but we are very confident that before the end of this year we'll have revenue generated from more than our anchor customer in a board and a connector applications.
But as for the anchor customer, and we have been engaging with them very tightly in the immediate next generation after the current one, so we don't have content to interconnected racks because it's a single-rack solution. But going forward, we understand that our product is in their design, in the form, either on the board or in a cable form.
As for this air pocket of three, four quarters, I mean, the most specifically for that one customer, one application. The other applications and revenue could come sooner than that.

Harsh Kumar

Understood. Hong, I'm sorry for the long-winded question, but thank you, very helpful. And then I just wanted to ask on your core business. You've been growing when every other analog company has been down because primarily you entered the correction earlier, you started correcting earlier.
Do you feel like you have good visibility on being able to call for, call it, sequential growth from here on? Or are you at a point where maybe just like your industrial business, you're starting to see where you've normalized and normal seasonality comes into play? Or are we still looking at growth from here?

Hong Hou

Yeah, that's a good question, Harsh. So certainly, we are having been over-indexed, I would say, on the attention on ACC or CopperEdge and the data center growth. But we do indeed, for Semtech has a broader portfolio.
So the other businesses, and we have been seeing the inflection in the FY25. You look at the historic numbers, and we have been able to record quarter-over-quarter sequential growth. We're going to be guiding one quarter at a time, but we're seeing the trajectory.
As Mark gave the detail, we will continue to see the data center growth even factoring in the ACC or CopperEdge headwind and the high-end consumer, we will have the tailwind for the seasonality. But sequentially, in our guidance for Q1, the industrial part will probably see a little decline.
But yes, the trajectory we see the business fundamental is there and is very favorable. And we have taken care of the inventory issues. So I think whatever we see going forward is going to be the true fundamental from the business. I'm very optimistic about that.

Operator

Tim Arcuri, UBS.

Tim Arcuri

I'm wondering if you can help us just on sort of pinpointing the timing on this upcoming step change in the revenue inside of data center. I know given this pushout in ACC, you are, though, winning on a couple of other platforms. So I'm just wondering if you can help us shape sort of in fiscal '26, like when is that step change going to happen?

Hong Hou

Thank you, Tim. So yes, as I said, the data center, we got a pretty broad portfolio, CopperEdge and FiberEdge and Tri-Edge product. And the fundamental of the CapEx spending by the CSPs is still there. We expect the FiberEdge continue to grow. The CopperEdge is going to be a little bit bumpy.
Temporarily, we have an air pocket. But once all the other customers, they start kind of ramping up in the volume, we'll see the accelerated growth.
But all-in-all, if you look at the data center portfolio, we still expect quarter-over-quarter growth. As for the timing of the CopperEdge recovery from that specific anchor customer, I think it depend on the next-generation rack design timing. That is a, I'd like to help whatever we can, but we can't control that timing.

Tim Arcuri

Right, right. Okay. And then I guess the second question is sort of an update on the portfolio rationalization plans. Is the current uncertainty in the market, obviously, what's happened in the last couple of weeks, I would assume that makes that maybe a little more challenging?
And can you speak to sort of how price sensitive you'll be in this? I mean, is the idea just that you want to rationalize the portfolio, not at any price, but I'm just kind of wondering how price sensitive you'll be given some of the market uncertainty we've seen in the past couple of weeks.

Hong Hou

Great, Tim. So we don't have a specific time line. As you know, that our balance sheet has been significantly strengthened. But from a longer run strategic point of view, we still would like to rationalize and kind of like having that our portfolio aligned with our strategic vision and margin profile. So the business has inflected.
And I think the good buyer, they will see the synergy from their side. So I would say this business need to be bought rather than be sold, namely that we don't have to sell it. But if the buyers see the strategic synergy for them and adding to their portfolio being transformational, and this can be a great addition to them.
So we are patient, but I know there are tailwinds because the -- as in the prepared remarks and one industry participant based in China was put on the DoD 126H list and another Europe-based competitor and exited the cellular module business. So really, the demand, we're seeing the booking activities has accelerated.
That's a really good business. It's contributing to positive EBITDA, and we are not in dire situation or have to do the sale. This is not a distressed asset. We welcome buyers to see the synergy and to their -- nice addition to their business, and it will be the basic principle for us to run this process.

Operator

Quinn Bolton, Needham & Co.

Quinn Bolton

Hong and Mark, congratulations on the nice results. I guess, Hong, maybe just a quick clarification on your data center comment. You mentioned that business growing quarter on quarter despite the CopperEdge air pocket. Was that a comment specific to the April guide? Or is that a comment that you see continuing throughout all of fiscal 2026?

Hong Hou

So nice question, good question. So we will only give the guidance on one quarter at a time. That's a specific guide to our April quarter. But in general, we go with the market trend. If the CSP CapEx spending continue to be strong, we have been benefiting from that trajectory and scored a very strong year-over-year growth from FY24 to '25.
If the CapEx continue to be as projected, and I will not be surprised that we will have a strong growth year over year as well.

Quinn Bolton

Got it. And then the second question is, I'm not sure if you're willing, but I was wondering if you might be able to give us some sense of the general breakdown of the data center business. You mentioned it was $50 million in the January quarter. It sounds like CopperEdge was probably a very high single-digit million, maybe approaching $10 million. But the rest of the business probably $40-plus million.
Can you give us a sense how much of that $40 million plus is FiberEdge just going into DSP-based optical modules, how much maybe Tri-Edge and then other revenue? Just trying to get a sense of what that mix looks like.

Mark Lin

Quinn, I think it's important for us to focus on our data center portfolio rather than individual SKUs. But I mean, needless to say, there's strong broad-based growth across our portfolio. We did mention in our prepared remarks that FiberEdge net sales for our fourth quarter were at record levels. So definitely strong market acceptance and market adoption of that FiberEdge portfolio.

Quinn Bolton

Maybe, Mark, just a quick follow-up. Could you say is the majority or perhaps the vast majority of the non-CopperEdge business driven by sort of 400 gig, 800 gig modules? Or is there a meaningful portion that may be targeting slower speed applications in the data center? Just trying to get a sense.
There's pretty strong demand for 400 to 800 gig and soon to be 1.6 gig optical modules. And just want to try to get some sense how much of your business is exposed to those higher speed optical modules.

Mark Lin

Quinn, broadly 400 gig, 800 gig, broadly, that's where we have a good sense of growth and then slower speeds as well, but that 400 gig to 800 gig is a good growth for us.

Hong Hou

That's a sweet spot and 1.6T is still early. It's more in the design phase and low volume. So 400 gig and 800 gig, there's a sweet spot of FiberEdge revenue contribution.

Operator

Christopher Rolland, Susquehanna.

Christopher Rolland

My first are on IoT and LoRa. So I don't know if you guys can frame the impact of u-blox and the block on the China list, what that means for that business? And then LoRa seems like a lot of upside there that $37 million number, like is that just pure LoRa modules or are there like routers and stuff in there? It seems like that was a big uptick. And is that sustainable moving forward?

Hong Hou

Thank you, Chris. So let me try to answer your LoRa question. First, the $37.1 million is all LoRa and we do not provide modules. We provide LoRa chips, transceiver chips to the module manufacturers in our different generations product, it just provide additional functionality and the inclusion of different video protocols to make the ecosystem partners use our product easier so that we enable -- provide that level of enablement. Most of the LoRa devices at this point, the end devices is not the gateway devices because they get a pretty good coverage on the gateway and also there are many different applications is point to point.
As for the IoT business, and certainly, you named the u-blox that we named the European participants. Yes, their announcement has provided a tailwind for us. We share the same customers, and we're getting the same customers calling us and asking for continued support and accelerated delivery. So that's totally helpful. Then the China-based company, the DoD list certainly provide another level of tailwind.
And there are some customers in the past, they have shifted effort to design our product into their routers and gateways, but they took us as an approved vendor just in case they couldn't buy from that company, they will buy from us. But now we are seeing some tangible shift and because some of the -- for example, some of the applications they can use for commercial applications, they can be installed in the military base.
Clearly, they wanted to use the same modules for both applications, and they wanted to source from Western suppliers like us. And we will be benefiting from that even more going forward. Right now, we're seeing more design wins, but those design wins is going to be converted into orders and bookings throughout the year.

Christopher Rolland

Excellent. And sorry for misspeaking on modules versus chips. I did know that, but is LoRa -- these levels sustainable from here and then as a follow-up for some handset-related questions on either TVS or proximity sensing, as you look out this year, next year, how do you view kind of your opportunity set in these markets moving forward? Would you consider them better than market growth or how would you consider them?

Hong Hou

Thank you. Yes, on the LoRa and certainly, the Q4 was very strong, and there might be some factor in there for kind of like some project-based demand. But in general, if we zoom out a little bit year-over-year basis, we have been experiencing very strong growth.
I will think based on the momentum, based on the customer engagement activities, based on the new use cases we learned from our creative ecosystems and customer base, I am pretty optimistic for the year-over-year growth from FY26 to -- FY25 to '26. For the TVS and PerSe product for cell phones and smartphones, I believe we are gaining shares.
And that has been supported by the year-over-year revenue growth and double-digits. And certainly, that is higher than the smartphone market itself. And the quarter-to-quarter basis, you're still going to be seeing a little bit of seasonality impact. But in general, we are getting more design wins, and we are gaining shares from our competition as well.

Operator

Cody Acree, Benchmark Company.

Cody Acree

Congrats on the progress. Mark, for you, if you can just talk about your gross margin expectations for the year? And maybe also if you can expand on into your OpEx expectations for the year?

Mark Lin

Cody, I'll just emphasize we're only guiding one quarter out, so beyond our guide. We don't have that much commentary other than we've seen very strong year-over-year growth in our gross margins. And given that we are looking at some additional data center growth, we do see that those are typically higher than our corporate gross margin averages, so accretive to total gross margin.
On OpEx, we've guided one quarter out. I'll just say that we're remaining prudent in our R&D spend. So R&D is prioritized to customer alignment and what we believe will be near-term revenue growth.

Hong Hou

Yes. If I can add some color. Cody, on the OpEx side, you see the incremental increase in our Q1 compared to Q4. If we kind of like a double-click on that, SG&A is going to be stay largely the same. Over the year, we wanted to have more efficiency and leverage with increased revenue, and we plan to use AI.
Right now, that is a hot topic, but we really see the benefits for some efficiency and productivity improvement. We do want to increase the R&D spending in our FY26 compared to FY25. And over the last three quarters since I took the position, and we have conducted multiple critical reviews on the programs, the return on the R&D programs, we canceled a number of it and so that we can make the fund available to programs with better opportunities. We did that and has been largely successful in FY26.
Going forward, we have more opportunities and just by shifting the focus a little bit may not be enough. So we wanted to increase our R&D spending in this new fiscal year. But as Mark said, in a very disciplined fashion. So we definitely wanted to make sure we will review the return on the investment.
We'll review the alignment with the market frequently so that if we need to do any adjustment or course correction, we'll do it decisively. But in general, we see many opportunities, and we wanted to really capture those opportunities to accelerate the growth. So we'll see the R&D spending for the Q1 is going to be increasing a little bit from Q4. But other part of the OpEx, we wanted to make sure we can get the efficiency out of them.

Cody Acree

Hong, if you can just continue with that thought then, can you elaborate on your product priorities then for '26, where your R&D spending is going to be focused? And where do you think your growth is going to be most derived from?

Hong Hou

Good question, Cody. So we certainly wanted to focus our R&D in the area that we have demonstrated a very fast growth, and we have a better alignment with the customers, and we have opportunities identified. So largely in the data center area, in the LoRa area and in some selected IoT areas as well. And of course, the new emerging trend, well, not an emerging trend, so among our portfolio, like person sensing is quite exciting because of the SAR standards requirement is elevating that provides opportunities for us to provide solutions to our customers with our technical differentiation.
And then the same product can be used in the gesture control for the smart wearable devices, and that is an emerging opportunity. And in the beginning, we were just kind of like provide a solution to it. But now -- and that can be -- if it really materialized, can be the next-generation compute platform with the AI form factor.
And then the robots, we know our person sensing product has been incorporated in many companies in the robot designs. So that's a pretty exciting opportunities, and we will be increasing R&D investment to create extended bandwidth in addressing the market need for that application.

Operator

Tristan Gerra, Baird.

Tyler Bomba

This is Tyler on for Tristan. Maybe back on LoRa. Could you provide an update on where LoRa inventories are? Do you think you're shipping back in line with demand? And then also, if you could help with the timing of the ramp for the Mercedes factories, that would be helpful.

Mark Lin

Yes. Tyler, not just with LoRa, but across our portfolio, we are monitoring channel inventories. So we try to keep channel inventories in line with expectations, right? So that goes for LoRa, too. So we're really shipping to what we believe is expected demand.
LoRa deployment across the industrial portfolio, that example you provided that Mercedes deployment, that occurred already. But right now, LoRa is being deployed across a number of IoT applications, metering, asset tracking, factory automation.

Tyler Bomba

Great. And then maybe for my follow-up, one on the data center. Could you just provide a little more color on where you're seeing LPO opportunities medium term?

Hong Hou

Yeah. So Tyler, the LPO opportunities near term is going to be primarily on the 800 gig or 100 gig per channel. So we have been providing our TIAs and driver solutions to many optical transceiver module manufacturers. And there are some strong CSPs at the end user to drive the adoption for it.
And as for 1.6 terabit, I think at this point, the industry is primarily focusing on LRO solution, namely in the transmitting end, they will still use the DSP-based real-time solutions and the receiving end, they will use the linearized solutions. So LRO, we will have our TIA in the receiving end but we don't have the driver, the driver typically come from the DSP side.
The 800-gig LPO on the other hand, we will have the TIA content on the receiving end together with the driver content on the transmitting end. So at OFC, you're going to be seeing multiple demos that our customers and the partners are using our solutions to design and plan to go into the production on the 800 gig LPO and 1.6T LROs.

Operator

Craig Ellis, B. Riley Securities.

This is Stacy on for Craig. I was wondering if you could just give a little clarification for the announcement with currently one competitor being placed on the entity list. How has that been like materialized so far in lifting the Sierra business? And how would that affect the business strategically?

Hong Hou

Yeah. So Stacy, thank you for that question. The one competitor was placed on the 126H list. That means really many of our customer base when they have the product used for in-due use situation, they do not want to use the modules from that supplier in China. So that definitely has translated into a significant increase in booking. So as I said, that a significant increase in design wins and the design wins is going to be translated into the bookings throughout the year.

Got it. And the second question, I guess, is going back to kind of the design process, like how long are these onboarding conferences can last? And how many AI server generations can that socket remain?

Hong Hou

I see. So the design for onboard solutions is actually going to be shorter than the design in the cable because the onboard solutions typically done by the end customers directly. They don't need to go through a third-party supplier.
So the design cycle, like anything, typically 6 to 18 months. It depends on the number of reasons they will have. So you probably will be learning more about the timing in the next week's conference, they're going to be hosting.

Operator

Kyle Smith, Stifel.

Kyle Smith

This is Kyle on for Tore at Stifel. Congrats on two straight quarters of positive free cash flow. So how should we think about free cash flow heading into fiscal '26? And maybe building off of that, if you could provide general expectations for both operating cash flow and capital expenditures, that would be great.

Mark Lin

Kyle, thanks for the question. We'll say that we're only guiding one quarter out, but you can see the strong cash flow generation that we had in Q4, and we had sequential increases in cash flow generation from Q4 to Q3. Definitely strong business fundamentals do help with the growing business, but also with our reduction in debt, we previously announced $40 million in annual cash interest savings. That's definitely a tailwind to our operating cash flow metrics.
And that operating cash flow, we only had a partial quarter of benefit in our Q4. So you can expect or I expect that there's going to be some incremental cash flow benefits over the year. Again, we're only guiding one quarter out, but I would think that historical CapEx is a reasonable proxy going forward for future CapEx requirements.

Kyle Smith

Great. And as my follow-up, could you maybe provide an overview of the unbundling trend you're seeing within the TIA market? And do you feel you can capture the majority share within the unbundled TIA market in the next few years?

Hong Hou

Yeah. So definitely, we can see the prior commercial arrangement from the industry participants and usually leverage the availability and shortages of DSPs, they wanted to sell DSP and TIA together. I think with the more availability of the DSP supplies and the number of providers out there, this kind of bundling practice is no longer in place, and that provides great opportunities for us to play in the level market playing field.
So we have been gaining market shares but I think we still have ways to go. And the good thing is our TIA has been broadly regarded as the best solution in the industry, serving 200 gig, 400 gig, 800 gig, and 1.6T. So we have multiple form factors, and I anticipate that trend will continue.

Operator

Harsh Kumar, Piper Sandler.

Harsh Kumar

I was curious, Mark or Hong, what is making LoRa jump up so significantly so fast? Are you seeing some kind of new deployments or activity? And maybe you could help us understand what geo or what kind of applications are without giving us too much specifics.

Hong Hou

Yeah. So Harsh, that's a great observation. We're really pleased with the results. And I think it's largely due to the customer focus. And the business in LoRa has been auto-piloting for a while.
And now we put a very concerted effort and developing new products and providing enablement support and really engaging with the customers very closely. So it's clear that LoRa has demonstrated very strong differentiating capabilities compared to other RF protocols and customers are developing different applications.
There are a lot of innovation going on there. And when people talk about the auto lawn mower and robots and metering that's the space, and we have been demonstrated a very strong demand, but there are new applications being developed. So I think we are accelerating the growth through new product offering and ecosystem enablement and customer focus.

Operator

Quinn Bolton, Needham & Co.

Quinn Bolton

Just wanted to ask a quick question on the PON business. Just looking at the overall Signal Integrity revenue and your comment that the data center was up to $50 million. It looks like you probably saw a meaningful step down in the PON business.
Just wanted to see if you could confirm that. And if that's the case, is that just sort of timing between different tenders? Is that a seasonal effect? And then I've got a quick follow-up.

Hong Hou

Yes, Quinn. So for Q4 results was actually year-over-year, the PON was growing. And as for our guidance, say, in the SIP area, the Signal Integrity product overall is going to grow. The data center is going to grow. So PON and it has some timing thing related to the tender offers.

Quinn Bolton

Okay. And then I'm not sure if you care to comment, but your growth for Signal Integrity or, data center in particular for the April quarter. Just wondering, do you expect the CopperEdge business to be effectively zero in that quarter? Because if so, it obviously implies some really strong growth outside if the overall bucket is going to grow quarter on quarter.
But just wondering if you could give directionally, is CopperEdge still several million dollars? Is it zero? Just any help just to sort of think about growth outside of the CopperEdge product.

Mark Lin

Quinn, in our Q1 guide, we still expect to be recording CopperEdge net sales. CopperEdge doesn't go to zero, but it's just under our prior expectations at our customer. So as Hong said, there's still design activity. We're engaged with over 20 customers, and we expect some revenue to pick up at the latter half of FY26.
