Thank you, operator, and good afternoon, everyone. Welcome to Wolfspeed's fourth quarter fiscal 2026 conference call.

We encourage you to reference the slides that were published on our IR website today. Please note that we will be presenting non-GAAP financial results during today's call, which we believe provide useful information to our investors.

Non-GAAP results are not in accordance with GAAP and may not be comparable to non-GAAP information provided by other companies. Non-GAAP information should be considered as a supplement to, and not a substitute for, financial statements prepared in accordance with GAAP.

A reconciliation to the most directly comparable GAAP measures is in our press release and posted in the Investor Relations section of our website, along with a historical summary of our other key metrics. Today's discussion includes forward-looking statements about our business outlook, and we may make other forward-looking statements during the call.

Such forward-looking statements are subject to numerous risks and uncertainties. Our press release today and the SEC filings noted in the release mention important factors that could cause actual results to differ materially.

With that, I will turn the call over to Robert.

Thank you, and good afternoon, everyone. We appreciate you joining us today.

This quarter marks another step in building momentum since we substantially refreshed our leadership team and capital structure. Our fourth quarter revenue results of $150 million represents another quarter of delivering results at the midpoint of the guidance range and further demonstrates we're delivering on our commitments.

Reflecting on this past fiscal year, we have proactively taken aggressive actions, including recapitalizing the company to strengthen the balance sheet and bolstering our leadership team and our sales organization with seasoned industry veterans. We have also adjusted our go-to-market sales strategy and positioned the company to refocus on our technology leadership and a customer-centric approach.

While we have accomplished a lot as we continue to deliver on our commitments, we remain early in our transformation, and as each month and quarter passes, we continue to gain further confidence in our path to profitability as we execute our strategic priorities and navigate broader industry dynamics. As I said on my very first earnings call leading the Wolfspeed team, we have enormous potential underpinned by strong foundational elements.

Since then, we've been proactive building upon these strengths by attracting and incorporating industry veterans with extensive customer relationships to leverage, optimize, and capitalize on our physical, operational, and intellectual assets. Most recently, as announced late July, Andy Mattes was appointed to our board of directors.

As the former CEO of Coherent and Diebold Nixdorf, with more than 40 years of leadership in semiconductor and advanced technology industries, brings a strong record of strategic leadership, operational excellence, and industry relationships to further bolster and accelerate our path to profitability. Also, in early June, we announced the launch of a dedicated data center solutions team to capitalize on the further growth in our fastest-growing end market.

To lead this effort, we appointed two industry veterans in the San Francisco Bay Area, the epicenter of tech innovation, who have extensive experience in high-voltage power architecture for AI and data center applications. Our investment and focus in AI data center applications is gaining momentum, reflected in both revenue growth and expanding customer traction.

In fiscal 2026, revenue in this business more than doubled versus fiscal 2025, including increasing approximately 20% from the fiscal third quarter to the fourth quarter. We continue to see encouraging progress as new design wins ramp at leading power supply companies, including Lite-On, Megmeet, and others to support multiple hyperscaler customers.

These wins span both established and emerging HVDC AI architectures. The transition to 800-volt architectures is increasing silicon carbide content across the data center power ecosystem.

As these next-generation power architectures become a critical enabler of AI infrastructure, hyperscaler customers are placing greater emphasis on system efficiency, quality, and supply assurance. Beyond AC/DC power supplies, we're seeing opportunities emerge across battery backup units, supercapacitors, e-fuses, and high-voltage DC-to-DC conversion.

We're also pursuing opportunities on the secondary side of high-voltage DC-to-DC conversion systems, which could further expand our addressable market over time. While the market remains in its early stages, we believe our technology leadership and available manufacturing capacity position us well to participate in this long-term growth opportunity.

With industry-leading SiC technology and differentiated vertically integrated 200 manufacturing capability, we are well positioned to support this transition as AI data center adoption continues to scale. These are all clear examples demonstrating the team is executing and delivering on the key strategic priorities we committed to.

I will also comment on a few updates regarding our commitment to technology leadership, another key strategic priority. This past June, we announced two significant achievements at PCIM, a leading power technology conference in Europe: Gen 5 MOSFET technology and 10 kV MOSFET commercial readiness.

At PCIM, we announced our fifth-generation silicon carbide MOSFET technology, marking another significant milestone in our innovation roadmap. Gen 5 MOSFETs deliver the best specific on-state resistance in the industry while maintaining the excellent switching behavior introduced in our Gen 4 MOSFETs.

This combination represents a substantial performance leap in efficiency over competitive solutions, giving our customers the option to maintain efficiency and reduce the overall size of their systems, or maintain system size and achieve greater power density. Gen 5 enables more compact traction inverters, extended EV driving range, right-sized battery systems, and improved EV charging infrastructure, directly addressing the cost and efficiency pressures faced by automotive OEMs.

Beyond automotive, Gen 5 also addresses several industrial power supply applications demanding leading-edge performance, including AI data center power supplies, solid-state transformers, and renewable energy conversion. Importantly, Gen 5 was developed and is running in our highly automated 200 facility in Mohawk Valley in upstate New York.

This provides our automotive and industrial customers with a rapid, low-risk path from design-in to volume production. While we are diversifying our revenue and customer base beyond our historical core concentration, as discussed above, we are also continuing to develop and improve our automotive customer relationships.

To this point, our previously announced partnership with Toyota for onboard charging systems reflects the continued importance of silicon carbide in next-generation EV platforms. More recently, we were awarded first-time business from a European Tier 1 supplier supporting the onboard charger for a large German OEM.

To touch on the aerospace and defense market briefly, our 10 kV silicon carbide MOSFET was acknowledged at the PCIM as the top innovation at the conference. We also recently announced a memorandum of understanding with GE Aerospace to accelerate the adoption of high-voltage silicon carbide across the industrial, aerospace, and defense market.

This technical partnership includes the supply of the industry's first commercially available 10 kV SiC MOSFET from Wolfspeed and will ensure co-development of standard high-voltage power module formats. This domestic partnership strengthens our supply chain resilience and aligns with US government priorities around critical technologies for AI, energy, defense, and national security.

In our materials business, we continue to serve a broad range of power and RF-based customers, including our 150 LTA customers. We are also working closely with them on their 200 transition by providing state-of-the-art samples and technical support.

Our increased focus, customer-centric approach, and operational discipline continue to be the backbone of these relationships. Regarding our 200 substrates, we continue to explore new opportunities and make steady progress.

Since our last update, we have begun shipping the first engineering samples to multiple customers for their internal evaluation. We continue to view this as a longer-term growth opportunity.

Prior to turning it over to Gregor, I will close by saying thank you to the entire Wolfspeed team for their continued commitment, execution, and drive. Our strategic alignment is significantly improved, with new leadership, a new sales strategy, and a stronger capital structure, better positioning us to capitalize on long-term industry trends.

This will continue to strengthen our earnings potential and we believe will ultimately deliver significant value creation for shareholders.

Thank you, Robert, and good afternoon, everyone. In addition to the key strategic priorities reviewed by Robert, we have also made great strides with our operational excellence initiatives, which will continue to increase our earnings potential and differentiate us in the marketplace as partner of choice.

I will turn to our fourth quarter results. We generated $150 million in total revenue for the quarter, in line with the midpoint of our guidance.

Materials revenue was approximately $43 million. Power revenue was approximately $106 million, which represents 6% sequential growth as the quarter benefited from strength in AI data centers, which increased approximately 20% from Q3 to Q4 and more than doubled from fiscal 2025 to fiscal 2026, which helped to compensate for the softer results in automotive.

Next, our adjusted non-GAAP gross margin for the quarter was -19.9%, reflecting a 70 basis points sequential improvement. This was driven primarily by product mix, including higher I&E sales in Power and higher RF sales in Materials.

Underutilization continues to be the primary driver of our gross margin profile, and improving factory utilization remains one of the most important levers to drive margin expansion. As I mentioned during the third quarter earnings call, we continue to focus on producing the same revenue with less capacity consumed.

These continued efforts position us to keep expanding our earnings potential per dollar of invested capital, even if it makes the reported underutilization appear larger. Non-GAAP operating expenses totaled $62 million in the quarter versus $61 million in the prior quarter, largely due to continued investment in R&D and marketing-related expenses.

Adjusted non-GAAP EBITDA for the quarter was -$62 million, comparable to the prior quarter. Gross capital expenditures were only $5 million in the fourth quarter versus $38 million in the prior quarter.

Changes in working capital contributed approximately $23 million to cash for Q4, driven primarily by continued reduction of inventory levels. Now, turning to cash flow, which remains one of our top priorities.

Operating cash flow for Q4 was -$54 million and included a $41 million benefit from further reduction of inventory levels in the quarter. We ended the quarter with approximately $1.1 billion in cash and short-term investments, allowing us to pursue our strategic priorities with confidence.

We continue to pursue aggressive efforts to reduce our debt and cost of capital. During the fourth quarter, our capital structure further improved as holders of $46 million of our 2L convertible notes exercised a voluntary conversion of their debt to equity.

This debt principal decrease resulted in approximately $1 million of annual interest expense savings. Net debt was approximately $600 million at the end of the quarter.

Turning to our business outlook, we continue to see growth in our device business and are targeting revenue between $140 million and $160 million in the first quarter of fiscal year 2027. We are expecting non-GAAP gross margin to remain negative.

As we are entering the new year, we are now expanding our guidance to include non-GAAP operating expenses, and we expect them to be in the range of $62 million to $66 million in the fiscal first quarter of 2027.

Thank you, Gregor. Before we open the call up for questions, I will reiterate, we are laser-focused on continuing to deliver on our key strategic initiatives, including technology leadership, diversifying our revenue and customer base, operational excellence, and financial discipline.

Cumulatively, this will cement our path to profitable growth, stronger earnings power, and greater value creation for our shareholders. With that, operator, we are now ready to take questions.

Hi, and thanks for the question. I guess my first is just going to be a pretty simple near-term question.

When it comes to automotive and industrial, your primary customers, what are you seeing? What does the outlook look like both for materials and devices?

Are you confident that June is the bottom for this business?

Thanks for the question. It's Robert here.

Pretty much what we see is that our diversification efforts in terms of broader customer structure globally is really starting to pay off, right? Then, of course, we cannot influence the demand of our OEM customers, but what we can clearly see is that pretty much both in the I&E space and also in the auto space, we see really good traction.

Then again we also announced here one additional design win now at a German car OEM for onboard charging and we see really a broad engagement across the globe. How the overall demand will develop across these end verticals is hard to predict, quite frankly speaking here.

As also some of our customers are going through product mix changes, especially on the auto side here, I think that's something which is rather hard to predict.

Thank you, Robert. Maybe as a follow-up, there's a ton of interest in AI.

You've talked about AI revenue. I don't know if you have any projections perhaps for next year and where you might be, but if you could talk about the progression of products that you will be releasing to market and/or have design wins for.

Obviously, you had the announcement with Lite-On. I believe that's for PSUs for a sidecar.

I don't know if there's any timing around that, but SSTs beyond that, perhaps even with your 10 kV solutions. Maybe if you could talk about the progression and new product opportunities and what that timeline might look like.

Absolutely, great question. Pretty much, we doubled our revenue from FY 2025 to 2026.

That just shows the kind of momentum this market segment has gained. Quite frankly speaking, this was not on anybody's radar screen a couple of years ago.

In terms of the product portfolio, here we're quite frankly looking into again like you said on the PSU side, discrete devices. Here we are engaged, and we named two of these companies, Megmeet and Lite-On in our press release also here.

Of course we're engaged across the whole ecosystem on the power supply side. Then working with the major solid-state transformer companies on the higher-voltage devices, which are primarily 2.3 and 3.3 kV modules.

Here it's around how do we get the end customers, which are the hyperscalers, comfortable pretty much with the reliability aspect and also making sure that they're comfortable pretty much deploying these SSTs. We're really engaged from 750-volt devices, 1200-volt devices, 2.3 kV devices, 3.3 kV devices, and again, the higher the voltage comes, the more differentiated the product portfolio is.

We have the products, yeah, and we have this in our 200 Mohawk Valley fab. Where we're getting a lot of requests from these customers is, okay, we're now going to go deploy this now, are you ready to ramp?

The good news is with us having completed the 6- to 8-inch transition, I think this is a huge asset for us as a company, right? As we're vertically integrated, that means we got the substrates, we got the products, and again, we're really all here to serve them out of the Mohawk Valley fab.

Hey, guys, thank you for taking my question. Maybe following up on Chris's last one.

I think you called out, great to see the data center business doubling, but it still remains modest. I guess any timeline you're able to offer us on when you would expect data center revenue to become more meaningful?

I guess how much of that is tied specifically to the 800-volt architecture versus broader compute and AI deployments? Thank you.

Again, there are a couple of factors driving the demand. One is, of course, the 800-volt deployment.

That's a big milestone here which is going to happen. Here we're working on various qualifications across the whole ecosystem.

Then also the whole deployment of solid-state transformers, right? This is where I talked about these 2.3 kV, 3.3 kV devices are really important.

Us being able to deliver these devices from our Mohawk Valley factory is putting us in a really good situation to take advantage of that demand.

Got it. Thank you.

Then for my follow-up, any help you can give us on the gross margin trajectory either near term or longer term? I guess for the medium term, what level of Mohawk Valley utilization or revenue is needed for gross margins to flip positive?

Thank you.

Thanks for the question. I think, indeed, gross margin neutrality is the next big milestone for us to drive towards.

That is particularly driven by volume growth. As we have a high fixed cost nature in our business.

Revenue expansion is the best way to improve our margins. Inherent profitability of the products is quite okay, I would say, it's really about asset utilization.

It greatly depends on the exact mix you have between devices and material, but also within material on the end markets. We're pretty happy to see that some of the industrial markets having a lot of traction, including the data center side.

In a ballpark, we would say on $800 million annual run rate, that's probably the ballpark where a breakeven gross margin point lies right now. Again, that could be plus/minus several million depending on the mix.

Hey, guys. Thanks for taking my question.

My first is, could you just take a minute and maybe come back and talk about what you could do in terms of cash management and specifically around the L1 and what that would save in terms of interest? I believe that is callable at this point in time.

What would that save you on annual interest and what would that do to your cash burn? Then I have a follow-up.

Hi, Jed. Thanks for the question.

Obviously, the first-lien debt is the highest-priority debt to refinance. Right now, it's around 16% interest.

Depending on the means of refinancing, you can calculate on the $630 million of outstanding debt how much saving that would be, but again, it depends on what type of refinancing or repayment that would be. It would be a meaningful contribution to the cash flow.

In this particular quarter overall, we have spent $32 million in cash out of the total $54 million in operating cash flow, you can see it's a meaningful amount. Obviously, that's not all coming from the L1, but a significant portion of that.

Got it. My follow-up question is that retiring the L1 would also unencumber the ability to break the business in two between materials and power.

Is that still the case? I believe the covenants previously had maintained that Apollo would have to sign off on that, but I'm assuming if the L1 was taken care of, that would unlock that covenant.

Not that you're planning on doing that, I'm just wanted to make sure that I had that correct.

I would say I don't go into that. We have absolutely no interest to break it in two, whether that's allowed or not is quite irrelevant from our perspective.

We believe that having a vertically integrated business drives in really a performance differentiator when it comes to our device performance. I think when you look at the Gen 5 product performance that we have released at the PCIM, we have seen a leap in performance that others have not been able to achieve with the technology in play, and we are convinced that this is to a certain extent contributed by the fact that we're vertically integrated.

Whether that may or may not be true, I don't think really is relevant for us at all.

Hi, good afternoon. Thanks for taking the time.

This is Akansh on for Joe Cardoso. Just had a broad question here related to materials revenue, was $43 million this quarter while you support 150 LTA customers through their 200 transitions.

How do we think about materials revenue from here and when does 200 begin contributing more meaningfully to the overall number?

We're working with all the major customers on qualifying the 8-inch 200 materials as we speak, and some of them are digesting inventory levels, and I think we're exactly in this transition from 6 6- to 8-inch. Some LTAs are running out, some LTAs on 150 are still continuing, and this is something I would say here which will continue for this year as we're seeing this transition here to happen.

As we see of course overall demand for silicon carbide and if you look into all the market studies, silicon carbide market is growing. This means also our customers on the material side will transition to 8-inch eventually, and then we clearly are in a very good position with leading-edge quality and leading-edge technology on 8-inch side to take full advantage of that.

Thank you.
