Chris Allexandre
Good afternoon, and thank you for joining us on today's second quarter 2026 earnings call. We appreciate your continued interest and support as we execute our strategic transformation to Navitas 2.0.
In the second quarter, we delivered increasing revenue of 22% sequentially, coupled with a stronger third quarter guidance. Higher-power markets grew more than 50% year over year, serving as further evidence of the building momentum in our GaN and high-voltage SiC products, especially in our focus area of AI infrastructure.
We're also delivering on our Navitas 2.0 transformation. We are well ahead, by over one quarter, of expected traction for nearly all sales to be coming from higher-power market by year-end, with revenue contribution from mobile and low-end consumer being insignificant.
We continue to deliver step by step on what we said we would do, and this quarter serves as another proof point of our consistent progress. Over the past several quarters, we have aggressively pivoted the entire organization to focus on higher-power market, where Navitas GaN and high-voltage SiC technology can deliver meaningful differentiation and increase long-term value.
The resource reallocation and organizational realignment is now substantially complete. With new leadership in place and a refreshed product and technology roadmap, we are sharpening our focus on AI infrastructure, which comprises both AI data center and the grid energy infrastructure required to power them.
Combined, these AI infrastructure market represent the vast majority of our long-term serviceable addressable market for GaN and high-voltage SiC, and underpin our future growth trajectory as a higher-power company. Turning to a closer look at our reported results and progress for the second quarter.
As previously mentioned, total revenue increased 22% sequentially to $10.5 million, driven by growth across our higher-power markets. Higher power represented a majority of our overall revenue mix, with revenue contribution from mobile in Q2 declining both sequentially and year over year, as in the prior quarter.
I also want to highlight that both GaN and SiC contributed to our sequential growth, with a particular acceleration in our SiC business during the quarter. As expected, we also delivered expanded gross margin as a result of more favorable revenue mix towards higher value, higher-power product, and improving scale.
Notably, our strong momentum continues to build and accelerate into the second half of the year. Our expanding backlog extend beyond '26, coupled with record book-to-bill, supporting our expectation for continued double-digit quarterly growth through the second half of the year.
The third quarter will also represent a return to year-over-year growth driven entirely by higher-power markets. This also translate to achieving mid-single-digit revenue growth for the full year, while simultaneously having substantially exited the mobile and the low-end consumer market.
This is a significant change in the revenue composition for the company, and clear evidence that we are delivering on the Navitas 2.0 transformation. With growth increasingly driven by a combination of AI data center and grid and energy infrastructure, we expect AI infrastructure market will represent more than 1/3 of our total sales by year-end, setting the stage for continued momentum in 2027.
While we are nearing completion of our transformation to a higher-power company, our focus continue to be grounded in four key pillars: market focus, technology leadership, operational efficiency, and financial discipline. Starting with our focus on higher-power market, the rapid adoption of AI is driving immense market demand to overcome critical power bottlenecks across AI infrastructure, including both AI data center and grid and energy.
As a result of Navitas's unique ability to deliver higher-power product leveraging both GaN and high-voltage SiC technologies, we are benefiting from accelerating momentum to enable customers' higher-power application within AI data center as well as the grid and energy infrastructure needed to supply them with power. Together, those two areas of AI infrastructure represent the large majority of our long-term SAM, growth trajectory, and where the company is headed.
In AI data center, we're currently generating growth ahead of the market transition to 800-volt DC. For example, increasing power level in AC-to-DC power supply units are driving the need for higher density, which in turn is accelerating the replacement of silicon with our high-voltage SiC.
We are also actively engaged with hyperscalers, merchant power customers, data centers OEM, ODM on multiple program ramping in the second half of '26 that will accelerate throughout 2027. We're also seeing strong traction in DC-to-DC PSUs and battery backup units, where both our SiC and GaN solutions are being designed in.
Again, this activity is happening today in advance of the 800-volt transition. In fact, we continue to believe that the transition to 800-volt architecture for next-generation AI data center will happen in 2027, as various XPUs, GPUs, hyperscalers will introduce it at different times, and it will unfold in a series of steps.
Each step will represent an inflection point that drive increasing momentum and explosive growth for Navitas's higher-power GaN and high-voltage SiC content. I will briefly walk through each of those inflection points, which are also outlined in the earnings-related slide deck that we've posted to the investor section of our website.
What's clear is the evolution to 800-volt is inevitable, as it remains the industry's only path forward to achieve much higher power and higher-density AI racks. The first inflection point, second-half '26 ramp and accelerating in first-half '27: SiC adoption in AC-to-DC PSUs is being driven by power scaling and density requirement, independent of the 800-volt DC initiatives.
As the AI data center racks require more power, it is driving higher-power level AC-to-DC PSUs, which ultimately drives higher density, and therefore accelerating the replacement of silicon by SiC, even with 50-volt DC output. This is already underway, and the growth is happening now and will continue throughout 2027 and beyond.
Following, there will be a second inflection, ramping in mid-2027: first, the introduction of the 800-volt busbar in the sidecar rack, with power system elements such as AC-to-DC power shelves and BBU moving from the IT rack to the power sidecar with output of 800-volt DC to the IT rack. This change is bringing additional high-voltage SiC content in higher-power AC-to-DC PSUs, now with 800-volt DC output, plus new SiC and GaN content in top-of-rack DC-to-DC PSUs and BBUs.
We are in advanced system design and reliability testing with several key customers, and are preparing the ramp. Then the third inflection point, ramping mid-to-late 2027, really accelerating in late '27 and early 2028: the integration of the high-density DC-to-DC conversion directly into the GPU and XPU trays using GaN for its superior switching frequency and power density in megawatt-scale rack across various GPU and XPU and hyperscalers at various times.
At that point, a fundamental change happen in data center IT rack power architecture: 800-volt comes in straight to the server trays. This is what most are referring as native 800-volt.
We're highly confident in our position for 2027 ramp with our GaN. Simultaneously, the AC-to-DC PSU will continue to be in higher demand for high-voltage SiC, with increased power level and density, on top of BBUs and other power systems.
Lastly, there will be a fourth inflection point, 2028 and beyond. This is where solid-state transformers come into play, and on-site data center taking mid-voltage AC electricity from utility grid and directly converting to 800-volt DC, which get distributed across the data center.
This is the full 800-volt DC evolution, with ultra-high-voltage SiC and GaN across grid modernization, solid-state transformers, and end-to-end power delivery from grid to core with full wide-bandgap solution. Complementing this significant opportunity within AI data center is the equally large and even longer-duration market opportunity in grid and energy infrastructure.
Today, we're actively advancing design activity and sampling across BESS, solar string converters, PSUs, and solid-state transformers application. Our recently introduced 2.3 kV and 3.3 kV GeneSiC modules are receiving excellent feedback, and customer have begun requesting volume samples for system-level testing in the second half of the year.
We're also seeing early interest in our new isolated TO-247 family, which offers unique advantage in liquid cooling application. Importantly, I want to re-emphasize that Navitas remain technology agnostic, and we are prepared to offer customers the optimal solution, whether that be GaN or high-voltage SiC across the full power chain from grid to rack.
This unique flexibility allows us to capture whatever content per system as well as support multiple architectures. As previously mentioned, both GaN and SiC are contributing to current growth, and we expect AI infrastructure to drive the substantial majority of our revenue and growth going forward.
Turning to our second key pillar, technology leadership is essential to our success, and we continue to diligently invest in innovation and expanded product roadmap for both GaN and high-voltage SiC. On GaN, we are advancing our reference platform solution, including the 800-volt to 6-volt DC-to-DC power delivery board demonstrated at recent industry events, with an 800-volt to 12-volt version in development.
We have kicked off new program utilizing Navitas's unique solution to maximize system efficiencies the secondary side for 800-volt data center power topologies. Our industry-leading DFN 8x8 dual-side cooled package continues to gain broad adoption for its superior power density, thermal performance, and board space savings.
Our 650-volt 11 milliohm GaN FET remains the lowest RDS(on) high-voltage GaN device in the industry, and we have a significant number of customers preparing for mass production. Additionally, our medium-voltage GaNSense GaN is seeing increasing adoption for secondary side and other application.
On the high-voltage SiC, our GeneSiC technology, based on our proprietary trench-assisted planar architecture, continues to differentiate with its best-in-class reliability, efficiency, and manufacturability, attributes that are increasingly critical as voltage scale from grid and energy infrastructure application. We recently introduced our isolated TO-247 product family spanning 1.2 kV to 3.3 kV, delivering module-like performance with standard discrete footprint with integrated isolation for direct cooling and simplify customers' manufacturing.
As mentioned earlier, we're also seeing customer traction in both AIDC and grid and energy infrastructure application. We also recently expanded our SiC portfolio with newly introduced 1.2 kV JFET product line to be released early next year.
Initially targeting AI data center, solid-state transformers, and energy grid infrastructure application, our new JFET product line opens door to address an additional $1 billion of incremental SAM by 2030. Also, we continue accelerating towards our ambition to deliver best-in-class ultra-high-voltage SiC technology and product, and already in discussion with selected customers regarding the planned third quarter release of our new 6.5 kV SiC technology, which we expect to unveil very soon.
Additionally, we are currently engaged on the development of next-generation 10 kV SiC devices with a prominent lead customer, and expected announcement in coming weeks. In addition to expanding our existing SiC portfolio and technology, last week, we announced a strategic partnership with MagnaChip to license our GeneSiC Gen 4 and Gen 5 trench-assisted planar technology spanning 1.2 kV, 2.3 kV, 3.3 kV, and higher voltage.
Supported by our supply chain and material ecosystem, the technology will be ported, qualify, and internalize in their fab in South Korea. This partnership delivers two primary strategic benefits.
First, it will enable expanding adoption of our SiC technology across more target markets, expanding Navitas technology beyond the current focus. Second, and longer term, this collaboration facilitate establishing of another foundry source of Navitas SiC wafers, ultimately strengthening our supply chain resilience and supporting our ability to efficiently scale GeneSiC solution.
Our deliberate strategic decision to prioritize AI infrastructure over automotive, unlike some of our competitors, has allowed us to bring focused, high-performance product to market faster. Having both GaN and SiC is also seen by customers as a key differentiator, and it allows us to focus on customer needs, independent of any technology bias.
Additionally, this has allowed us to secure initial design wins with key customers that will continue to support our long-term growth trajectory for years to come. Operational efficiency: with respect to operations, we are making excellent progress on our strategic partnership with GlobalFoundries.
Lead parts from our pivot to 8-inch GaN are on track for customer sampling and qualification before year-end, and we expect to have initial qualified product in early 2027. This transition will enable US-based GaN manufacturing, supporting national security application and long-term supply chain resilience.
I also want to note that we have secured appropriate buffer capacity at TSMC to ensure a smooth transition for existing customers throughout '29 and beyond. In addition, we continue to further strengthen and streamline our supply chain, consolidating to fewer, more strategic OSAT partners that are better equipped to support higher power at scale.
Internally, we're also increasingly leveraging AI tools across designs, operations, and other functioning to accelerate execution and improve efficiency as we scale. In terms of the fourth pillar, maintaining financial discipline continues to be a fundamental operating principle.
Over the past 9 months, as we've transformed the organization, we've realized significant efficiency and have held operating expense essentially flat. With our transformation now substantially complete and with a clear visibility into accelerating growth, we are prudently increasing investment in specific areas, including expanded product development like our JFET or IsoTO, strengthening customer support for key committed program, and enhancing operational readiness for upcoming ramp of volume shipments.
Each of these objectives are directly aligned with our goal of capturing the substantial multi-year growth opportunity for GaN and high-voltage SiC solution across AI infrastructure markets. Also, we recently raised additional capital to further strengthen our balance sheet and support ongoing strategic execution.
More specifically, with $557 million of cash at quarter end, we now have increased flexibility to fund strategic investment in our business, including our Foundry Plus program, capacity expansion, and supply reservation agreement with our foundry partners, as well as potential strategic inorganic opportunities. That being said, I want to be clear that our immediate and overarching focus remains on driving strong top-line growth, together with gradual gross margin expansion through improving mix and scale, while maintaining an unwavering path toward becoming a profitable higher-power company.
In closing, I'm very pleased with our continued progress and growing momentum. Q2 represents another proof point that we are executing on our strategic Navitas 2.0 transformation.
We are delivering on our commitment to achieve quarterly growth by year-end, will have substantially completed our transition to a higher-power company, and expect to be back to year-over-year growth. This majority of the growth is being driven by AI infrastructure market.
This is also supporting our expectation for continued double-digit growth for the second half, setting the stage for continued growth momentum into '27 and beyond. With our substantial cash balance and market leadership, we are well positioned to deliver sustained growth as we capitalize on the opportunity to enable the AI revolution with our differentiated higher-power GaN and high-voltage SiC.
With that, I'll pass the call to Tonya to review our second quarter financials and the third quarter outlook.
Tonya Stevens
Thank you, Chris. Before I begin, please note, unless otherwise indicated, I will focus my comments on non-GAAP results.
A detailed reconciliation of all non-GAAP to GAAP financial measures can be found in our press release published earlier today. Revenue in the second quarter of 2026 was at the high end of guidance, increasing 22% sequentially to $10.5 million.
This represents an increase of approximately $1.9 million from the $8.6 million in the first quarter. As Chris highlighted, the double-digit growth was driven by increased traction in high-power markets, which grew more than 50% year over year, and reflects a notable improvement in our revenue composition as our mobile and low-end consumer business continues to be a smaller portion of overall revenue.
We continue to expect this historical business to become insignificant by year-end. As a result of improved product mix and higher quarterly revenue, gross margin expanded by 50 basis points sequentially and 100 basis points year over year to 39.5%.
Our accelerating shift in overall revenue mix towards higher-value, high-power markets and away from mobile and low-end consumer remains fundamental to our ongoing gross margin expansion strategy. We continue to expect gradual improvement in gross margin throughout the year as we drive top-line growth in high-power markets, coupled with expected return to year-over-year revenue growth.
Operating expenses for the second quarter were $15.5 million compared to $15.0 million in the prior quarter and $16.1 million in the same quarter a year ago. Operating expenses for the quarter continued to reflect our commitment to focused and disciplined spending.
OpEx was at the high end of our guidance range as we began making incremental investments in the business, particularly in new R&D programs to accelerate growth. Having diligently maintained effectively flat OpEx in recent quarters during our strategic transformation, we are increasingly focused on the resources and investments required to support the longer-term success and sustained growth of the transformed company.
As such, we are targeting a prudent increase of approximately $1.0 to $1.5 million in quarterly OpEx beginning in the third quarter. This equates to a roughly 10% increase, yet remains meaningfully lower than our expected top-line growth rates.
The incremental OpEx will be allocated to scaling the business, including investments to accelerate new product development, strengthen our engineering and application support for key committed programs, and reinforce operational readiness in advance of expected growth in ramping shipments. Loss from operations in the second quarter was $11.4 million compared to a loss of $11.7 million in the prior quarter and $10.6 million in the second quarter of 2025.
In Q2, weighted average basic and diluted shares outstanding were approximately 240.7 million, resulting in a Q2 loss per share of 4 cents, flat to the 4 cents per share loss in the prior quarter, and compared to a loss of 5 cents per share in the year-ago second quarter. Before moving to the balance sheet, I want to briefly provide additional context related to our reported GAAP net loss for the second quarter.
Results on a GAAP basis included a non-cash charge of $203 million related to the October 2021 business combination earnout share provisions that were contingent upon stock price appreciation targets. These earnout shares were deferred merger consideration paid out to stockholders in connection with the company's de-SPAC transaction.
This earnout was fully recognized and settled by the end of Q2, and no further charges related to it are expected. As such, going forward, there will no longer be an associated line item for the change in fair value of this earnout liability reported under other income or expense on the company's statement of operations.
Turning to the balance sheet, cash and cash equivalents at the end of the second quarter 2026 were $557 million compared to $221 million at the end of the first quarter. The increase in cash and cash equivalents primarily reflects the additional capital raised during the quarter of approximately $373 million at an average stock price of $21.89, which meaningfully strengthened the company's balance sheet and overall financial position.
As a reminder, the company continues to have no debt. In addition to bolstering liquidity and working capital flexibility, the significant added capital ensures ample resources for accelerating our continued transformation into a scaled high-power company.
This includes strategic investments in support of advancing our Foundry Plus initiative, potential capacity expansion, and supply reservation agreements with our US-based foundry partners, as well as potential pursuit of selective strategic opportunities. With respect to inventory, we ended the second quarter with $19.5 million of inventory compared to $14.9 million in the prior quarter, reflecting the start of our build of appropriate buffers of TSMC wafers to ensure a smooth transition for our customers.
This buffer inventory is also reflected in an approximately $15 million increase in Q2 prepaid expenses and other current assets on the balance sheet until the wafers are received as inventory in future quarters. The sequential $4.6 million increase in Q2 inventory and $15 million prepaid for future anticipated wafer receipts primarily reflects our measured investment to support customers' future anticipated AI data center growth.
More broadly, channel and distributor inventory remains at healthy levels. Moving to guidance for the third quarter of 2026, we expect accelerated sequential growth, with revenue increasing 28% to $13.5 million, plus or minus $0.5 million.
At the midpoint, this also represents a return to year-over-year growth while reflecting a completely different revenue composition as we rapidly shift away from mobile and low-end consumer, with growth driven by high-power markets and specifically AI infrastructure. Non-GAAP gross margin is expected to be 39.7%, plus or minus 100 basis points, which at the midpoint represents a 20 basis point increase, reflecting a continued favorable shift in revenue mix toward high-power markets and some additional improved scale.
As previously discussed, we are moderately increasing our investment in OpEx going forward to further accelerate our expected future growth. Non-GAAP operating expenses are anticipated to range between $15.5 to $17.5 million.
That concludes our formal remarks. Operator, please open the call for questions.
Operator
Thank you. We will now begin the question-and-answer session.
If you have dialed in and would like to ask a question, press star 1 on your telephone keypad to raise your hand and enter the queue. If you would like to withdraw your question, press star 1 again.
On today's event, we request everyone to please limit yourself to one question and one follow-up only. Thank you.
Your first question comes from Quinn Bolton from Needham & Company. Please go ahead.
Quinn Bolton
Chris, Tanya, thank you very much for taking my question. Congratulations on the nice third quarter outlook.
Chris, I guess I wanted to start, there's been a lot of noise and sort of chatter in the market that 800-volt architectures may be delayed, including confirmation, I think, that Nvidia's Kyber rack may have been cancelled to be replaced by something as of now that's unannounced. Given some of this noise around 800-volt architectures, can you just sort of comment on what you're seeing in terms of adoption of 800-volt and whether there's any impact on your 2027 revenue outlook as a result of perhaps architecture shifting around?
Chris Allexandre
Thank you, Quinn. This is Chris, and I would have bet you would have asked that question.
We provided in the earlier comments the steps, okay? I called that the inflection points.
I want to reiterate that thanks to the fact that we have both GaN and SiC, we are able to grow ahead of the 800-volt. Number two, you probably saw that what I call the inflection two is the introduction of the 800-volt through the power sidecar, right?
By the way, that's valid as well for the plus or minus 400-volt, which is used for the XPUs and the ASIC. You can see there, there's already a step, okay, in the usage and a step up in the content in both GaN and SiC.
Moving to the third inflection point, which is I think what you're referring to, so-called native, okay, 800-volt, where the DC-DC conversion moves down to the GPU tray. Of course, I'm not going to comment on Nvidia and Kyber plan.
I believe they've made a communication about their plan, and I would refer you to that. What I would tell you, though, is I think there is a misconception in the 800-volt being a digital switch.
If you look at the inflection number two, it's actually the start of the 800-volt through the sidecar rack. That's number one, which will drive more SiC and more GaN content.
Number two, even if you look at inflection number three, which is where the GaN content really step up as you move the DC-DC into the compute tray and you have no choice than use GaN because of the switching frequency, the one thing I would tell you is you have multiple GPUs, you have multiple XPUs, you have multiple platforms. What we see is that this ramp will happen in steps throughout '27, of course, accelerate in '28, but it's not a one thing, okay, and one customer.
The short answer to your earlier question, do we see that as a change in outlook? For us, the answer is no.
I think that goes back to multiple times you heard me saying that having both GaN and SiC is a strategic advantage for us to capitalize to capture content, and is even more so today.
Quinn Bolton
Got it. Thank you very much.
Then I was wondering, Chris, if you could talk about sort of applications for your new silicon carbide JFET product line that you discussed on the call. Is that mostly AI infrastructure, energy grid infrastructure?
Kind of where are some of the initial applications you'll target with the silicon JFETs?
Chris Allexandre
Thank you for that question. It's actually a very strategic decision that we made to expand our SAM.
As I mentioned, this will add nearly $1 billion of SAM by 2030. I think onsemi has even referred to $1.3 billion of SAM by 2030.
This is essentially a product that is very well suited for safety-critical application. The focus here is going to be both AI data center and the energy grid infrastructure.
You find it in applications like E-Fuse, O-ring, of course, solid-state circuit breakers, anything that helps to protect. As you move to higher power, circuit protection and power protection has become a bigger thing, and I think it's a SAM that will actually accelerate in the future.
I'll just give you an example. I just met an SST customer, right?
We've been talking about ultra-high-voltage SiC for a while with them. Just the fact that we can offer 1.2 kV up to 3.3 kV JFET, the SAM that we could capture in that SST went up by 40%.
Okay? Thank you for the question, I'm glad you noticed it.
This actually is a significant decision that we've made to expand the portfolio with JFET.
Quinn Bolton
Excellent. I'll go back in queue.
Thank you.
Operator
Thank you. Your next question comes from John Tanwanteng.
Please go ahead. I'm sorry, John.
Can you hear me? Oh
Operator
yes. I'm sorry, I got dropped.
You can go ahead and ask the question now.
Okay. Congrats.
Then second, I was wondering if you could talk a little bit more about the MagnaChip deal. Is that a volume- or fixed-fee-type of deal?
When do you expect it to contribute? Would it be this year or next?
Then after that, do you expect any more licensing to follow on the back of that as well?
Chris Allexandre
Thank you, John, for the question. This is Chris.
Appreciate the question. We just announced that partnership with MagnaChip, which, by the way, goes beyond SiC, but we just announced the SiC portion.
It's a validation of the technology merits and benefits of trench-assisted MOSFET from GeneSiC technology that we've been in business for quite some time. This is not so much about the licensing.
Of course, it will over time play in our revenue stream, but this is not the prime objective. Number one is to expand our SAM because, per the press release we made, MagnaChip is actually going to focus on market that we don't serve.
It's actually going to augment our ability to reach more customers, more market, and more SAM with our GeneSiC technology. Number two is it creates an opportunity for us to partner with MagnaChip in the foundry context.
As we talked about, as we see the huge demand ahead of us and the SiC growing at a 60% to 70% CAGR in the context of data center and grid, I think having more opportunity for us to secure capacity is essential, right? We're not creating a competitor.
We're creating an extension of Navitas, and we are very much looking forward to the partnership in the years to come with MagnaChip.
Got it. I appreciate that color.
Second, could you possibly comment on the Wolfspeed litigation? What's going on there?
What do you think your chances might be, and kind of what's at risk? Okay.
Chris Allexandre
I'm sure you understand that I cannot comment on the specifics of the pending litigation. What I want is to give already some context around the litigation.
I'll refer to the Wolfspeed because you had the question about Wolfspeed, but I'll refer as well to the Renesas litigation that just came last week, right? The other thing I would say is everything I'm going to say is actually on public record.
Number one, Wolfspeed already sued us because we stopped buying wafers from them a while back. Then they sued us or they sued two of our employees that worked at Wolfspeed in the past, including one that they had rift, okay, in their cost-reduction effort a while back.
Then they even tried to file, and they failed, a restraining order when third-parties recruiters were calling their people for job positions we had online on the web. They failed.
Now they sue us for patent infringement, okay, in both GaN and SiC. In my opinion, this is the last step in a campaign of harassment and intimidation through litigation.
Looks like a desperate move. Then two weeks later, just last week, okay, Wednesday, Renesas sued us.
I'm not sure it's clear for everybody, but I want to make sure everybody understands that based on the public record, Renesas would own up to 39% of Wolfspeed. Is all this a coincidence the week before the earnings, and all this coincidence?
I let you decide. Then, as I said, the timing is bizarre, okay, and curious, okay?
We've been in GaN and SiC for more than a decade, and yet we just got sued by by Wolfspeed. I left Renesas more than a year ago in June '25.
I'm coming up to one-year anniversary in in Navitas, and yet we just got sued by Renesas last week. All this the week before earnings.
I don't think this is a coincidence. Let's face it, and I give you my my view there.
You don't start litigation like this if you are winning market share, your technology's superior. You heard today our financial results.
You heard the momentum we are building. I gave you the detail of the four inflection points we see for both GaN and SiC, and the momentum we have with customers.
We're making a lot of progress. Sorry for the long-winded question answer, but I'll leave you with two things.
Number one is what we filed in the 8-K when the Wolfspeed litigation came. We respect IP and and technology.
Actually, the company is a result of decade of innovation coming from startups, okay, in both GaN and SiC, and we'll defend ourselves. Number two is we let everybody draw their own conclusion on why now Wolfspeed and their major shareholder are running to the courthouse instead of competing in a fair way in the marketplace.
That's going to be my only comment on this case during that call.
Got it. I appreciate the color, Chris.
Thank you.
Operator
Thank you. Your next question comes from Madison Paola from Rosenblatt Securities.
Please go ahead.
Madison De Paola
Hi. This is Maddie calling on behalf of Kevin Cassidy.
Thanks for taking my question. Just in regards to the MagnaChip partnership, what other technology licensing opportunities are you considering?
Then I have a follow-up after that.
Chris Allexandre
We licensed to MagnaChip, as I mentioned, Maddie, the GeneSiC technology.
Madison De Paola
Yeah.
Chris Allexandre
We're not in the business of licensing our technology. We are in the business of serving customers and growing the top line of Navitas and starting this multi-year growth journey that I talked about with the AI infrastructure.
We're always open to license our technology to partners and people we can partner with.
Madison De Paola
Great. Then you mentioned the record book-to-bill and backlog extending beyond 2026.
How much of that of the expected 2027 growth is supported by the committed programs versus programs that are already or are still in qualification? Yeah.
Tonya Stevens
I'll start. This is Tonya.
Maddie, thank you for your question.
Madison De Paola
Hi.
Tonya Stevens
Hi. We aren't breaking out what percent is committed in 2027 or what percent relates to our backlog.
What we can say is what gives us confidence is the various inflection points that Chris described in his prepared remarks, and them coming on top of each other, it's a compound growth effect. The fact that we have both GaN and SiC, which are both critical to gaining content.
Few competitors have both, and having both allows us to participate, like Chris said, in all of those inflection points. Then also what gives us confidence is the number of programs that are moving through qualification and into production, including design wins and DVTs, EVTs, and PVTs.
Chris Allexandre
Maddie, it's a very good question. I'll add two things.
Number one is you probably saw that we directionally gave you a sense of beyond Q3 how the business is going to continue, right? The reason we did that is despite mobile going down even faster than we talked about, we're going to grow more than we expected.
We are surprised, and I'm sure you are surprised, by the momentum that we have in the business and the outlook that we have. That's pre-800-volt, as I mentioned.
That's very important, I think, to understand. Now this is not one program, as Tonya said.
This is multiple hyperscalers, multiple OEM, ODM, multiple power level of the AC-DC PSUs. That continues to the inflection number two, okay, which will be some high in '27.
For me, what gives me confidence is there's a bit of a shift of the view. I think up to now, the view was the growth of Navitas will come from one large GaN big socket that will come with the 800-volt transition native, i.e., inflection number three, and the SiC will come from the grid.
This is very different. Today, what we see is across AC-DCs, DC-DCs, BBUs, the 800-volt in the sidecar rack, in the compute tray, it's tens and twenties of programs.
Different programs, different boards, different customers. Some of them are SiC, some of them are high-voltage SiC, some of them ultra-high-voltage SiC, some of them are GaN, some of them are both SiC and GaN.
We've seen in a couple of cases that we have, especially for DC-DC PSUs and BBUs, both SiC and GaN. That's what give us confidence, Maddie.
Of course, we're not going to guide '27. We already gave you kind of directionally how Q4 is going to look like, just to make the point that the transition to Navitas 2.0 and to be a power company is essentially one quarter ahead, okay, of what I talked about six months ago.
That's all driven by this pre-800-volt and the sidecar rack acceleration that we see.
Madison De Paola
Yeah. Great.
Thank you guys so much.
Operator
Your next question comes from Joe Moore from Morgan Stanley. Please go ahead.
Joe Moore
Great. Thank you.
In terms of the 800-volt sidecar, you talked about mid-2027 timing. I feel like there's some sidecars in the market maybe sooner.
Can you talk about what's the progression for Navitas to penetrate that business?
Chris Allexandre
Thank you, Joe. This is Chris.
You actually absolutely right. I think when I referred to the mid-'27, it's actually really kind of when things accelerate.
I think what you're referring to, the sidecar rack earlier ramp is the plus or minus 400-volt, which I think is also more attached to some ASIC and XPU. You're absolutely right that we see, in particular, with AC-DC PSUs and DC-DC PSUs, and to some extent BBUs as well, that the sidecar rack, 800-volt or plus or minus 400-volt, is going to ramp earlier next year, okay?
What I tried to give in the slide and the remarks is trying to give a sense of the step functions of the inflection. I think clearly, there's going to be an acceleration in mid of the year, Q2.
We see programs ramping associated to the sidecar in the first half of next year.
Joe Moore
Great. Very helpful.
Thank you. Then in terms of the other markets, you talked about infrastructure as the third leg in the near Can you talk about what's happening on the performance compute and in the non-infrastructure and electrification side?
Chris Allexandre
On the high-performance compute, as the high-end computers are moving and accelerating the use of much higher power type of architecture, including even embedded GPUs, we see a raise of the power level of the PSUs, okay? I mentioned that in the last earning.
We moved from 65-watt, 100-watt type of chargers. Now we have customers doing 200-plus, 280-watt.
We see an acceleration in the GaN usage, and that's benefiting us. I would refer to some announcements that were made, for instance, by large US OEM in computing, for instance, that came up with a super high-end GPU-enabled notebook that basically includes a 280-watt charger, which is full of GaN, with a significant content.
At that point, you have about $5 to $6 of content of GaN. Then when it comes to the even higher level, we just released with a customer a 1600-watt, okay, platform that basically helps to power the super high-end gaming platform.
Those are, of course, not as high volume, but the content is so much higher that I think it has contributed to us. This business, as we mentioned in the last earning, has actually helped us to compensate and really kind of neutralize the us moving away from mobile ahead of the AI data center growth, right, which I mentioned with AI infrastructure being 1/3 of our revenue by Q4.
Joe Moore
Great. Thank you.
Operator
At this time, I would like to remind everyone, in order to ask a question, press star, then the number 1 on your telephone keypad. Your next question comes from Tristan Gerra from Baird.
Please go ahead.
Tyler Pamrone
Hi, this is Tyler Bombaugh for Tristan. Building on the last question, what are your expectations for revenue mix between high-end compute and data center exiting this year?
Tonya Stevens
I'll start. We don't break down our revenue by our high-power markets, the four high-power markets being data center, infrastructure—the two of those combined being AI infrastructure—then performance computing as well as industrial electrification.
Chris did give more context relative to, by the end of the year, we expect the AI infrastructure to be a third or greater of our total revenue by year-end.
Chris Allexandre
I think the way you should think about this is basically over the last 12 months, we pivoted from being essentially mobile-exposed to essentially being non-mobile-exposed. In the last earning, I referred to mobile being insignificant by the end of the year.
The reason why we kind of gave a sense about the year-over-year growth by the end of Q4 is to kind of really outline that it's actually even less than insignificant. We're not going to get specific about the numbers here, but I think I said in my early script that basically we are one quarter ahead of my expectation in term of mobile being gone.
That gives you a sense, right? Then the other thing that we gave color is the fact that 1/3 of Q4 revenue is coming from AI infrastructure.
You can see really this AI infrastructure being the acceleration of our growth, Q2 to Q3 and Q3 to Q4, which I think is why we came higher than the street expectation.
Tonya Stevens
Yep, and we've also said on prior earnings call and reiterate this time that AI infrastructure is growing at over 50% quarter on quarter, both in Q1 and in Q2, and we expect it to accelerate. It's accelerating every quarter.
Tyler Pamrone
Very very helpful. We've heard of price increases across the industry.
Are you seeing this trend for your products as well, and does that vary across silicon carbide and GaN?
Chris Allexandre
We've seen price increase in silicon. I think you've seen that across the board, and in other technologies like memory and so forth.
I'm not going to get specific about pricing increase with customers. However, as I said before, is as tension comes, you expect the pricing to go up.
Right now we're focusing on getting our customers to adopt these new technology and transition to the new architecture. Price increase in the core market, and I'm not referring to the market we move away from, has not been so far a focus on our side.
Great.
Tyler Pamrone
Thanks for taking the questions.
Chris Allexandre
You're welcome.
Operator
Your next question comes from Richard Shannon from Craig-Hallum. Please go ahead.
Richard Shannon
Thanks, guys, for letting me ask a couple of questions. First one for you, Chris, here.
When you talk about the four stages of inflection within AI data center, is there any particular stages of inflection that you feel relatively more or less confident about the share you're going to get? If so, do you have any way to characterize where those differences come from, like GaN versus silicon carbide, or where you have both, or anything else?
I recognize the difficulty in answering a question about stages in terms of time when, obviously, the four stages a couple of years out here, but love to get your sense on that, please.
Chris Allexandre
I think on stage one, it's happening now, okay? We are very excited about the amount of program and really something I mentioned in the earlier remarks is the acceleration of the replacement of silicon by silicon carbide, okay?
As you move to higher density and higher efficiency, higher power level, there's an acceleration there. Then when it comes to stage two, and we are in very advanced engagement and situation with the customer.
At this stage, this is not anymore prototype, right? This is basically large quantity, system-level testing, system-level reliability, should it be an AC-DC at 18, 23, 20 27, 30 kW or a DC-DC of 15 to 30 kW or even a BBU, right?
What I like about stage two is that it's multiple platforms, multiple hyperscalers, and multiple merchant power per hyperscalers. It's a lot of program, which I think give us kind of fairly good confidence that we're going to be able to capture a share.
When you go to stage three, what I like about this is we move from one customer, one large GPU vendor flipping to 800-volt native, as people call it, being now looked at not just in the GPU rack, but compute rack, but across multiple racks, across multiple XPUs, across multiple ASICs. I think the fact that we've been in GaN for so long, I think give us a leading advantage.
I think I'll refer to the announcement that were made and the partnership that we announced in the past with some GPU vendors or other hyperscalers. Then stage number four, I think the one thing I would change compared to what I said earlier, Richard, is stage number four, the big jump is SST, okay, when really the grid delivers you 800-volt.
What we see is a lot more application than just SST. I refer to BESS last time, PCS, and solar.
What I like is that, of course, the big jump is in '28 with the SST, but really kind of we start to see some nice ramp in 2027 as well with the other application, right? I think it's hard to give you where I think we're going to win more than the others.
What I like is that we don't chase one thing here, okay? It's multiple hyperscalers, multiple socket, multiple merchant power.
It's SiC, high-voltage, ultra-high-voltage, and GaN. Give me confidence that we're going to able to capture share.
Richard Shannon
Great, Chris, for all that detail. A second question is for Tonya on the OpEx here.
A couple of questions. You got a little bit wider range than you've had in the past quarters here, $2 million worth, and I may have also missed any dynamics of how to think about OpEx going forward here.
What's the variability of the size of the range, and how do we think about this over the next few quarters? Any seasonality, any other investment cycles, or should we expect it kind of largely flat for a period of time?
Tonya Stevens
Sure. Sure, great question.
The way you should think about OpEx and OpEx expanding, and we talked about this in the last earnings call, is relative to it being meaningfully less than our top-line growth, than our revenue growth. At the midpoint of our Q3 guide, that's a 28% revenue increase, and even at the high end of our OpEx guide, that would be approximately a 10% increase.
Meaningfully less, as in the 1/4 to 1/3 range, is how we think about it. You're right, we see a bigger step-up Q2 to Q3 than we're expecting going forward, because as Chris and I both talked about in our prepared remarks, we've held OpEx relatively flat for several quarters, and then are also meaningfully and purposefully investing in opportunities to accelerate revenue, and you're seeing that culminate in our revenue and our programs.
We talked about investing in new R&D projects like the JFET, like ultra-high-voltage SiC, the 6.5 kV, 10 kV, and beyond; more customer support programs as we ramp in the data center, including application engineering; and then that robust supply chain to make sure we're ready ahead of demand. That's kind of how you should think about that.
We've been doing all of that while keeping OpEx flat in the past and having less of a focus on China market. The first thing we did is make sure all of our resources were shored up and focused and shifting toward R&D versus other OpEx.
Then even within R&D, made sure it was all focused on high-power markets before we started investing again. That's how I would think of it, but still meaningfully less than the revenue growth.
You see the revenue growth accelerating, you see a little bit of an uptick in OpEx.
Chris Allexandre
I'll add something, Richard. I think our focus and eyes on getting this company to get profitable has not changed.
The focus is accelerate top-line growth and enabling the business with OpEx increase as a fraction of the revenue growth to stay on path for being profitable. With the large number of program I mentioned, with the multiple inflection points, with the fact that we feel there is a big opportunity for us to expand our portfolio, which means expand our SAM, we decided, with the growth coming sooner in second half compared to what we had estimated 6, 9 months ago when I started, we decided to pull the trigger a lot faster.
That's a conscious decision.
Richard Shannon
Sounds good. Thank you, guys.
Operator
That conclude our question-and-answer session. I will now turn the call back over to Chris Allexandre for the closing remarks.
Please go ahead.
Chris Allexandre
Thank you, operator, and thank you, everybody, for your interest and your question. I leave you with a couple of things, right?
5, 6 points which I want you to take from this call. Number one is the transformation to Navitas 2.0 is essentially nearly complete.
By the end of the year, as we told you, we are back to year-over-year growth despite mobile massive headwind, 4 quarters of sequential growth double-digit, and a complete change of the mix of the revenue, with essentially all revenue by the end of the year being higher power and mobile being gone. When I took that role a year ago, we talked about transforming Navitas.
I think today it is transformed, and now the focus is how do we execute the strategy, right? The transformation is working.
I talked about having both GaN and SiC being super critical, and we talked about the benefit in the inflection points of having both. We talked about some platforms using both GaN and SiC.
We talked about the fact that AI infrastructure is 1/3 of our revenue by the end, right? This is all kind of showing that the transformation is working.
The one thing I want to also highlight is this not one customer. This is multiple hyperscalers, multiple merchant power, multiple platforms, okay?
We referred to AC-DC PSUs, which is the first inflection, but I think we got the question earlier, AC-DC PSUs, DC-DC PSUs, BBUs, SSTs, multiple things, right? The way I view this is the AI is the catalyst of the large SAM that we go after.
We added $1 billion with JFET and the revenue transition to Navitas 2.0. So 2.0 is actually who we are, not who we're going to become, and that came one quarter earlier than I expected, to be honest with you.
Credit to the team and the Navitas employee that did this amazing job to transition this company. Now it's about execution and operational discipline to basically be on the path of multi-year growth journey and path to profitability, which I mentioned.
That's what I want to leave you at. This is a very important quarter for us because it's not talking about transforming, it's talking about transformed, okay, which is very important.
Thank you.
Operator
Ladies and gentlemen, that concludes today's call. Thank you all for joining.
