And now, it's my pleasure to turn the call over to Navitas' President and CEO. Chris, please go ahead.

Good afternoon, and we appreciate you joining us today. I'm pleased to be hosting my second quarterly conference call as Navitas CEO. We closed out the year with a productive fourth quarter, as we continue to accelerate our pivot to Navitas 2.0 and align the entire organization to focus on addressing high-power markets. In fact, it has been energizing 5 months since I joined the company, and my conviction in our industry-leading GaN and the high-voltage SiC solution has only grown stronger and that our strategic pivot is on the right path to successfully scale the company to the next level. Before providing comments and updates specific to the quarter, I want to briefly reiterate several key elements on our previously communicated strategic transformation and our vision to what we call Navitas 2.0. First, we're accelerating our pivot away from the company's historical mobile and low-end consumer business to focus on high-power markets, where our GaN and high-voltage SiC products can deliver real differentiation and value through higher density, efficiency and reliability. We are laser-focused on 4 high-growth, high-value market segments: AI data center, energy and grid infrastructure, performance computing and industrial electrification. Collectively, this segment represents a serviceable addressable market of $3.5 billion by 2030, split roughly 50-50 between GaN and high-voltage SiC with a combined CAGR of more than 60%. Although the largest portion of this $3.5 billion SAM are within AI data centers and grid and energy infrastructure, I want to emphasize that AI is a shared underlying catalyst across our 4 target markets, driving a rapid acceleration in terms of re-architecture infrastructure, customer expectation and the adoption of the new high-voltage technology. We're leveraging our proven 10-year track record as a pioneer of GaN at scale, having shipped over 300 million unit GaN devices, coupled with…

Thank you, Chris. In my comments today, I will take you through our fourth quarter and full year 2025 financial results. And then, I'll walk you through some of the important Q4 achievements and market dynamics as well as our outlook for the first quarter 2026. I will then return it to Chris for final remarks before we take questions. Revenue in the fourth quarter of 2025 exceeded the high end of guidance at $7.3 million compared to $10.1 million in the third quarter of 2025. As expected, revenue for the quarter reflects our strategic decision to deprioritize our low-power, lower-profit China mobile and consumer business as well as our efforts to streamline our distribution network to align our focus on high-power markets. As Chris mentioned, our high-power markets represented a majority of our quarterly revenue for the first time in the company's history, with mobile declining to less than 25%. This is a very important milestone and representative of our strategic shift. As mentioned before, we believe that Q4 represented the bottom for revenue, as our strategic actions support driving increased contribution from our high-power business going forward. Before addressing gross profit and expenses, I'd like to refer you to the GAAP to non-GAAP reconciliations in our press release. In the rest of my commentary, I will refer to non-GAAP measures. I would also like to point out that our GAAP results for the fourth quarter included a $16.6 million restructuring and impairment charge that consisted of approximately $10 million of distribution contract terminations, $4 million of fixed asset impairments and $2 million of workforce reduction expenses associated with realigning the entire organization and distribution channel to focus on addressing high-power markets. Of the $16.6 million restructuring and impairment charge in the quarter, $3.8 million was noncash related items.…

As we close today's call, I want to address one additional matter. After an extraordinary 10 years of dedicated service, Todd has decided to step down as CFO to pursue other opportunities. He has been an invaluable partner to everyone in the company, bringing financial discipline, strategic insight and weathering integrity that helped steer us through periods of both growth and challenges. Todd has also been a great partner over the last 6 months, helping to pivot and transition the company to Navitas 2.0. On behalf of the entire Board and executive team, I want to extend our gratitude for all of his contribution over the past decade. We have strong financial organization in place, and Todd is fully committed to assisting in a seamless transition until his successor has been made. We expect to communicate in the coming weeks regarding Todd's replacement and Navitas' new CFO. We enter in this new chapter with confidence in our strategy, our momentum and our ability to continue delivering long-term value for our shareholders. Thank you again for joining us today. Operator, we might now open the call to questions.

[Operator Instructions] And our first question comes from the line of Kevin Garrigan with Jefferies.

Chris and Todd, congrats on the results. And Todd, best of luck on your next path forward. Can you guys just walk us through how each of the high-power end markets performed in Q4? And how we should think about the trajectory for each of those markets in Q1?

Yes. Well, obviously, our quarter-on-quarter growth in revenue was due to the high-power markets. So they are performing well. We're not going to sort of break out the high-power markets at this time, but we do expect all of them to be performing on a go-forward basis as mobile becomes immaterial, as we move through the year.

Okay. Got it. And then as a follow-up, can you just update us on the progress of the 800-volt architecture opportunity? And can you give us a sense of a timeline on customer decisions?

Kevin, this is Chris. As we talked last time, there's a lot of work going on between us and the hyperscalers, not only one, but multiple of them on the adoption of the 800-volt HVDC. We sampled, as we mentioned in the press release and in the script, some of the new products that will be used in this type of architecture. We also announced a leading-edge 800-volt to 50-volt DC-DC brick that demonstrates the performance we can get with those products. So there's a continuation of collaboration. It's a bit too early to kind of tell you when this will be confirmed, but I think we are getting closer and closer with our customers.

Okay. Great. Congrats again on the results.

The one thing I would add, Kevin, is everybody refers to the 800-volt HVDC as a step function for power content in the AI data center, and this is true, especially with the adoption of GaN replacing silicon as you move to the 800-volt HVDC, right? But I would outline that in AI DC, and you heard it from multiple vendors, is that there is an acceleration of demand also in using the classic architecture, which is AC-DC, right, using SiC. And we see a growth throughout the year ahead of the step function with GaN in HVDC.

Our next question comes from the line of Kevin Cassidy with Rosenblatt.

Congratulations on the progress. Just as you mentioned you're working with the hyperscalers. Is this -- are you working directly with them? Would they be building their own power supplies? Or is that going to be a pull to -- from the current power supplies -- suppliers to the hyperscalers?

Kevin, it's actually all of the above, okay? So the hyperscalers, partly 2, are driving the new architecture, right, both in terms of what they expect in terms of density and power level in the AC-DC PSUs as well as the 800-volt either 50-volt or even lower voltage HVDC architecture, right? Now, we don't work only with the hyperscalers. If you think about PSU, which is clearly designed in OEMs and ODMs that are serving those hyperscalers, and if you look at the HVDC, a lot of these that are classic merchant power companies serving the hyperscalers, are also doing designs on this new architecture. So we work with everybody. I would tell you that the driver of the change of the architecture comes from the U.S. and the hyperscalers, but a lot of the OEM and ODM in Taiwan, in China, but also in the U.S. are driving that. And as you know, we just announced this board, right, which I mentioned, which was basically a co-development with the customer. And that's basically to showcase the level of efficiency you can get by using GaN on the primary side and GaN on the secondary side in 800-volt to 50-volt DC-DC brick. And you're going to see more of those reference implementation in the future as well.

Okay. Great. And have any of your customers or the hyperscalers giving you an idea of when that inflection point would be of when they start doing the installations?

I mean, the thing I would say is, as I said just earlier on Kevin's question, there are 2 stream, if you prefer, of the AI data center growth. Number one is more data centers, more power, and that drives more PSUs, higher-power PSUs and that drives the growth in SiC, which we are seeing throughout '26. When it comes to the 800-volt HVDC, which I think is your question, when there is a discontinuity and you cannot use silicon anymore on the primary side because you're 800-volt and you have to move to high-voltage GaN. This is really driven by not the GPU change, but the rack architecture change. As you compact more GPUs into a single rack and you get to megawatt rack, you cannot get the power density and the efficiency with silicon. And that's this discontinuity. I would say, as we said before, this is really about '27. Will GaN be used slightly earlier? It could. There is a case where you can use GaN in the 48-volt IBC replacing silicon, as I mentioned in the script, where GaN brings higher efficiency. You can do it with silicon, but you get higher efficiency. And this might be the first time you see GaN in data centers. But the real step function is really coming from the 800-volt DC, which is really kind of linked to the Kyber rack, which is the higher integration of GPUs in '27.

And also I'll give my best wishes to Todd, pleasure working with you.

Thanks, Kevin.

Next question comes from the line of Quinn Bolton with Needham.

Congratulations on the progress on the transformation to Navitas 2.0, and best wishes to you, Todd. I guess, Chris, I wanted to come back on the 800 HVDC solution, especially as you think about the primary side of that 800-volt rail. There are still a lot of folks in the industry that I think are talking about using silicon carbide in that 800-volt conversion step. You guys are obviously pushing the GaN solution. But I guess, can you say -- what are you seeing from the leading GPU and hyperscaler vendors that are looking at the 800-volt or the 400 plus/minus rack architectures? Are they pushing more for GaN? Are they open to both GaN and silicon carbide solutions? Just how do you see this playing out from a technology perspective between GaN and silicon carbide?

Thank you, Quinn. It's a very good question actually because I think there is some level of confusion. First of all, I would tell you that we are not pushing anything. We have both SiC and GaN, and we welcome SiC being used on the primary side if it's needed and GaN being used on the primary side if that's needed. So we're not pushing anything. We are being pulled. We've not seen any significant use case of board implementation of customer evaluation using SiC on the primary side. SiC is being used widely at 1.2 kilovolt, as I mentioned, in the classic AC-DC, right, which is basically prior to the 800-volt DC. But when it comes to 800-volt DC, we've been pulled by customers. And I'm talking about hyperscalers to Kevin's question here that are really driving the GaN adoption because it's more efficient and more driving higher density.

Okay. And then, Chris, you also talked about your 10-kilowatt all GaN brick solution. Can you give us a sense is that more of a reference platform? Or would that be a solution that Navitas would look to source that entire brick level product? Because I imagine it includes a fair amount of additional componentry. And so just thinking about to the extent you're selling the full brick solution, I imagine that might be pretty high-dollar content. So could you just talk about whether you would really just sell the GaN solutions as part of that brick? Would you sell the entire brick? And if you did sell the entire brick, what would the margin implications be?

So, of course, it's a very good question. Thank you, Quinn. We view this as an enabling solution enabling technology for the customers. So first of all, as I mentioned, this is something we've done with the customer. We have not done that in a vacuum on our own, right? This is something that we've co-developed with a leading customer, number one. Number two is we don't compete with customers, okay? At this stage, we don't see a path where we're going to sell the modules. Now, that design is shared with our customers and the hyperscalers as well as the ODM and OEM that are looking at how we've been able to achieve that high level of efficiency, right, 98.5%, which we believe, based on what we've seen and some of our competitors' feedback on top of customers, are one of the best in the industry, right? So I would tell you, this is for us -- this is what we've done in GaN historically. We pioneered GaN in mobile by demonstrating and helping customers to get to highest level of efficiency, lowest EMI, highest level of density. And we are doing the same in AI data center. And this is what I talk about -- when we talk about 2.0, we're leveraging the benefit and the skills of 1.0, right? And this system expertise makes a difference. At the end of the day, we are in the business of selling GaN and silicon carbide and enabling our customers. As a matter of fact, on that board, we're using some of our competitors in our silicon and other technologies and products that we don't have. But the focus is how to show and help the customers to accelerate the adoption of GaN in HVDC.

Next question comes from the line of Jon Tanwanteng with CJS Securities.

And I'll join the queue in wishing Todd well wishes on his journey. If you could start, maybe talk a little bit about the competitive landscape in supplying the 800-volt data center. What are you seeing just in terms of who you're bidding against in these sockets, if they're outpricing you or doing better in technology? And on top of that, how is your partnership with Infineon evolving in that space as well?

So thank you for your question, Jon. So I'll start with the end. We continue our partnership with Infineon. We have a cross license, as you know, and we share the same vision, which is to enable the accelerated adoption of GaN and silicon carbide in the AI DC, right, so SiC as the traditional architecture and GaN in the 800-volt DC, right? So there's a lot of dialogue between the 2 companies on that front, right? Number two, you all have seen that there are multiple vendors having been listed on the 800-volt AI factory kind of ecosystem. As a matter of fact, I think it's up to 13 vendors today. But we don't see all of them in each of the socket we target. So I would recommend that you look at how many of those 13 are actually in the high-voltage GaN, so how many of them have a 650-volt GaN in the right package to be able to enable 800-volt HVDC, how many of them have mid-voltage GaN to enable the 50-volt secondary side. Some of them are listed as a silicon vendor, okay? We are listed as a GaN vendor. The other thing is, as we talked about SiC being used on the AC-DC as well, there is a natural pull on more SiC as we get to higher voltage, and also outside of data center, to do the 800-volt HVDC, you need to enable a change of the grid architecture. This is a pure high-voltage, ultra-voltage SiC play. So what I will tell you is there's a lot of competition, but not everybody is competing on the same thing. And there are not many of the vendors being listed that have both high-voltage SiC or ultra-voltage SiC, either competing in the AC-DC with 1.2 kV or in the grid with 2 kV and above and having high-voltage and mid-voltage GaN. So this competition pool is actually being reduced. That's why we are very clear about what we do. We don't play in the silicon. We play in the GaN, high-voltage, mid-voltage and in the high voltage and high-voltage SiC.

Got it. And then second, could you update us on the incremental margin of either this 800-volt data center products or high-power products in general, especially as you roll out new suppliers?

So first of all, as Todd said, right, we expect continuous gross margin expansion. So remember that the growth this year is coming from all high-power markets and basically mobile going down, right, being less than 25%. What I would tell you is the scale is going to help more gross margin. As we grow revenue, some of our fixed costs absorb that and that drives margin expansion. Number two is the high-power products in the high-power market are coming at a higher margin than mobile was, okay? And that mix is going to change. And the third one is we are very active in ramping new suppliers, particularly on the package side that will help us to reduce costs, right? So there's multiple aspects of how we are confident to see gross margin expansion, as we clearly outlined for the rest of '26, right? And as we scale further in '27, we expect that to continue.

[Operator Instructions] Next question comes from the line of Jack Egan with Charter Equity Research.

I had kind of a follow-up on the gross margin question before me. So as mobile is getting smaller and smaller, I'm kind of curious about the longer-term outlook. Are your gross margins more so going to be driven by mix as in data center and non-data center end market mix? Or is it more kind of the technological innovation, I guess, that Todd mentioned that -- it sounds like it's referring to new products with higher ASPs? So I guess I'm trying to look at what the driver of the margins -- that margin expansion is, whether it's end market mix or better product margins?

So it's actually going to be a combination of both. So definitely end product mix, right? As mobile decreases, the high-power markets are going to give us higher margin. Those are more based on reliability and performance. But then on -- as we sort of scale and as these new products come into the high-power markets, we do expect like further expansions through like optimized process, yields and packaging costs, which will help drive our product cost down, thereby driving our margins up as well.

The one thing I would add, Jack, is, okay, scale, cost reduction and basically higher-margin product, right, as Todd said. But the one thing I would say is that, again, the growth this year, and I think we've been very clear that we are very confident that Q4 was the bottom, we are guiding up for Q1, and we said we're going to grow quarter-over-quarter throughout the year with margin expansion, I would reemphasize again that the growth is coming from whole high-power markets. Yes, AI data center is a big part of the future outlook. And if you look at the SAM that we shared just a few weeks ago, it's nearly half of the SAM that we see for us in 2030. But I would outline that performance computing is growing this year, okay? It will continue to grow and also help on the margin mix. Grid infrastructure is really accelerating. And I think you're going to see higher ASP products, higher-margin products coming in play there, where it's more about reliability and performance and less about cost. Of course, costs matter. And then, as we talked about in AI data center, which is a cost-sensitive market, it's all about efficiency right now, okay? And I think you're going to see all those markets contributing to the growth expansion in gross margins, right? So I just wanted to kind of calibrate a little bit your question to make sure that we don't see the gross margin expansion only coming from AI data center.

Sure, Chris. No, that's super helpful then. And then I guess, kind of from a higher level, I know you're not supplying as much into some of the automotive and industrial type markets, but silicon carbide has gone through -- just broadly speaking, has gone through a period of pretty significant oversupply. And so I was just kind of curious, what are your expectations on when that supply and demand in some of the other markets might balance out, whether for Navitas or whether the industry as a whole? I know that you're dealing with some large volume wins that so it might not apply to you as much, but just any commentary there would be helpful.

I mean, to be honest with you, John (sic) [ Jack ], I think, first of all, as an industry veteran, I would say it's going to take some time, but I think you should ask that to the vendors that are supplying into EV. We don't. We don't play in the same league of SiC, okay? You've seen me being very clear about the fact that we compete and focus on 1.2 kV for the PSUs for AI data center and 2 kV and above up to 5 kV and even more for the grid. This is where -- this is not about scale of supply, this is about how reliable and efficient and high performance is your technology. So I think for some of the SiC vendors operating at 450-volt, 650-volt, 800-volt focusing on EV, that's a valid concern. For us, it's about scaling with the ultra-high voltage, okay, which is nothing really related to supply at this stage.

Next question comes from the line of Richard Shannon with Craig-Hallum.

Apologies to ambient noise, I just jumped off the plane here and I missed a bit of the call here. So I hope I don't repeat any questions here. But Chris, one thing I'd love to ask you is in the AI data center opportunity here. To what degree are your opportunities coming from your partnership and kind of drafting behind, if you will, from Infineon versus other ways? And then also, are there any -- is there any cross-fertilization of wins within the rack between point of load and the 800-volt down? Do those kind of cross-fertilize and give you additional benefit at all?

So -- a very good question. As I mentioned, we partner with Infineon. We have a cross-license. We've done that a couple of years ago. We continue to drive collaboration to enable GaN adoption, both the high-voltage and mid-voltage. I would say that we don't leverage or benefit from Infineon. What you will see is -- I think I got a question earlier from Kevin, who are you bumping into most of the time? I would say it's probably Infineon and surely Infineon because they have the same vision. They have the same technology, high-voltage GaN, mid-voltage GaN and SiC and ultra-high-voltage SiC as well for the grid infrastructure. So there are very similarities. So we bump into each other. We follow each other, but I would not say that we leverage Infineon, right? Now, interestingly enough, when we released the package, we found that we -- because we talk to the same customers, we think the same way is we end up seeing the technology the same way. That's what I would say. On your question about expansion of portfolio, that's something we are looking at. My focus right now was to pivot the company, okay, and put every eggs we have, every engineer we have, every focus we have on the 4 high-power markets and the high-voltage GaN and GaN in high-voltage SiC. But we are looking at opportunity to expand the portfolio. As you get higher voltage in the data center, you're going to need circuit protection, and that's something we're going to look at in the future, right? But for now, we are laser-focused on execution with the product we have and we just released.

Okay. Fair enough. And the second question probably for Todd, just on the gross margins. If I caught the end of his prepared remarks, talked about not having enough scale to really drive leverage on gross margins quite yet here. Is there a revenue level by which that happens here? And kind of what's that fall-through margin when you start to see that trajectory?

Yes. That's a great question. As our mix changes, obviously, our margins will grow. But right now, we have that scale issue. We do see margins starting to expand again in Q2 and beyond. So that's sort of the tipping point right now.

What I would tell you, Jack, is the high-power markets and the high-power product in the high-power market are coming at higher margins. The mobile is going down. We said that in Q4, it was 25%, and we said it's going to continue to go down and get insignificant by the end of '26, right? So I think we are very confident that the mix of the mix change, the higher power product in the high-power market increase as a percentage of the company and the new product and the cost reduction we have will yield to gross margin expansion. So you'll see it right and clear, okay, starting not very far from now.

Okay. Appreciate that detail. And, Todd, good luck on your next endeavor.

Our last question comes from the line of Quinn Bolton with Needham.

Chris, you spent a lot of time talking about the high -the 800-volt data center opportunity. But you also talked about needing to re-architect the grid. And I just wondered if you could spend a second talking about the opportunity for the high-voltage silicon carbide and the solid-state transformers, sort of where are you in the design process for some of those solid-state transformers? And is there a way you can ballpark like what's the dollar content opportunity? I don't know if it's on a per megawatt basis or a per unit basis, but is there a way to size what the amount of high-voltage SiC that goes into a solid-state transformer, as they start to be deployed as the grid is re-architected?

Thank you, Quinn, for this follow-up question. Actually, I'm glad you asked that question because everybody focused on AI DC data center, and everybody is focusing on the 800-volt HVDC architecture, which is important because it's a discontinuity in the architecture. It's a replacement of silicon by GaN, right, or by high-voltage technology. But none of this is possible if the grid is not changing. And this is not just about getting a more efficient grid, it's a change of the architecture. And you refer to SSTs, which is basically getting from 35,000-volt AC super-high-power, high-voltage lines down to 800-volt DC at the highest level of reliability. That drives the change. And I tell you, I've never seen the grid infrastructure changing that fast. So you asked me, and I think we said it in the script and in the press release, we are accelerating the sampling of our 2.3 kV and 3.2 kV. Applications are any grid type application, SST, of course, but battery energy system, megawatt chargers, solar farm at the grid type level. Any of those applications are in accelerated designs, we are very busy talking to all those customers. That's why I said it's 2 legs, okay? We have 4 high-power market. But if I look at the future, those 2 legs, the AI DC and the grid are equally important. And this is a pure high-voltage SiC play. And to the earlier question about EV, this is not the same technology because what you have to deliver is high reliability technology, high reliable modules. So it's a different play, right? So I'm glad you asked the question. We see an accelerated design momentum. Of course, it's going to take time. This is longer design cycle than computing. It's longer design cycle than AI DC. But…

That concludes the question-and-answer session. I would now like to turn the call back over to the management team for closing remarks.

Thank you, everybody, for attending this call. As you could tell, we are very proud of the progress we are making. The first 5 months and 6 months since I joined was about pivoting the company and being clear about where we are going. I think we've done that. We are focusing on accelerating samples of our technology. We have 4 pillars of the transformation, which I mentioned: market focus, technology leadership, operational efficiency and financial discipline. And we'll continue to update you on how we make progress. And I think we have a bright future ahead of us.

Ladies and gentlemen, that concludes today's call. Thank you all for joining in. You may now disconnect.
