Wolfspeed (WOLF) is executing a strategic transformation, leveraging its strengthened capital structure and leadership to capitalize on the rapidly expanding silicon carbide market. Strong growth in AI data center applications, new Gen 5 and 10kV product introductions, and strategic partnerships are driving diversification. While operational excellence is improving, near-term profitability remains challenged by underutilization and automotive market uncertainty, further complicated by a recent legal investigation. (Updated: 2026-09-07)
Wolfspeed is demonstrating significant traction in high-growth AI data center applications, with revenue more than doubling in fiscal 2026 and growing 20% sequentially in Q4. The company has launched a dedicated data center solutions team, secured new design wins with hyperscaler suppliers like LITEON and MacMic, and is well-positioned for the transition to 800-volt architectures, expanding its addressable market.
The company continues to advance its technology leadership with the introduction of Gen 5 MOSFETs, offering industry-leading on-state resistance and efficiency, and the commercial readiness of its 10-kilovolt SiC MOSFETs, recognized as a top innovation. These products, developed in the vertically integrated 200-millimeter Mohawk Valley fab, are securing new business, including a European OEM win and a strategic MOU with GE Aerospace, strengthening supply chain resilience.
Wolfspeed has significantly strengthened its capital structure and is focused on financial discipline and operational excellence. The conversion of $46 million in 2L convertible notes reduced debt and interest expense. The company also received approximately $700 million in federal tax refunds authorized by the CHIPS Act in late 2025, bolstering liquidity. Ongoing efforts to improve factory utilization at Mohawk Valley aim to drive margin expansion and achieve gross margin neutrality.
Wolfspeed continues to face significant profitability challenges, with non-GAAP gross margins remaining negative at -19.9% in Q4 FY26 and projected to stay negative in Q1 FY27. Underutilization of its manufacturing capacity, particularly at Mohawk Valley, remains the primary drag on profitability, requiring substantial volume growth to reach the estimated $800 million annual revenue breakeven point.
Near-term demand in the automotive market remains uncertain due to end-customer product mix changes, making the outlook hard to predict. Additionally, the materials business, while working on 200-millimeter transitions, is experiencing some 150-millimeter LTA customers digesting inventory, leading to a sequential decline in materials revenue and indicating a prolonged transition period.
The company is subject to a legal investigation regarding potential securities fraud, citing Q4 FY26 revenue and adjusted loss per share significantly missing consensus estimates. This adds a new layer of risk. Furthermore, while some CHIPS Act funding has been received, the preliminary $750 million direct funding remains subject to potential delays or conditions. The capital-intensive nature of the business and the high cost of the remaining first lien debt (approximately 16% interest) continue to impact cash flow and financial flexibility.

This domestic partnership strengthens our supply chain resilience and aligns with U.S. government priorities around critical technologies for AI, energy, defense and national security. Our strategic alignment is significantly improved with new leadership and new sales strategy and a stronger capital structure, better positioning us to capitalize on long-term industry trends. We continue to see growth in our device business. We believe that having a vertically integrated business drives really a performance differentiator when it comes to our device performance. | Bearish-Leaning Quotes (Short)While we have accomplished a lot as we continue to deliver on our commitments, we remain early in our transformation. 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. Materials revenue was approximately $43 million. Adjusted non-GAAP gross margin for the quarter was minus 19.9%. Fund utilization 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. Adjusted non-GAAP EBITDA for the quarter was negative $62 million comparable to the prior quarter. We are expecting non-GAAP gross margin to remain negative. How the overall demand will develop across these end verticals it's 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. But it still remains modest. In a ballpark, we would say on an $800 million annual run rate, that's probably the ballpark where a breakeven gross margin point lies right now. Obviously, the first lien debt is the highest priority debt to refinance. Right now, it's around 16% interest. Some of them are digesting inventory levels. 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. | HiringWolfspeed has bolstered its leadership team and sales organization with seasoned industry veterans. Andy Mattes was appointed to the Board of Directors in late July. In early June, the company appointed two industry veterans in the San Francisco Bay area to lead its dedicated data center solutions team. |

| About Expanding Eligible MarketWolfspeed introduced the first commercially available 10-kilovolt silicon carbide power MOSFET and launched its next-generation TOLT portfolio, which are purpose-built for AI rack power and support the transition from 400-volt to 800-volt architectures. The company is also making progress on commercial scale 300-millimeter development as the market evolves and is engaging with AI ecosystem companies to explore how 300-millimeter substrates can address thermal, mechanical, and electrical challenges in next-generation AI and high-performance computing packaging architectures. Wolfspeed has realigned its go-to-market strategy around four verticals: auto, I&E (Industrial & Energy), aerospace and defense, and materials, strengthening its team with experienced automotive executives to target key global accounts for the next wave of design wins. In aerospace and defense, growth is supported by electrification trends and increasing demand for secure domestic supply chains, with expansion into emerging applications like electric aviation through partnerships with leading manufacturers. | About CompetitionWolfspeed highlighted a competitive advantage by having completed the shutdown of 150-millimeter device production at Durham and shifting all device production to 200-millimeter at Mohawk Valley, stating that many competitors are still on 6-inch and trailing in that conversion. This move allows Wolfspeed to assure customers of no Product Change Notifications (PCNs) as demand picks up. | About The Broader IndustryGlobal EV adoption continues to grow, though more modestly in certain regions, and silicon carbide revenue does not necessarily scale in lockstep with vehicle sales due to design-in and qualification cycles. Momentum in AI data center applications continues to build, with strong sequential growth observed in AI applications. The aerospace and defense sector is experiencing growth driven by electrification trends and increasing demand for secure domestic supply chains. While near-term demand in automotive remains uncertain, high-growth areas such as AI data centers and other I&E applications represent meaningful long-term opportunities. | Where Things Are HeadedWolfspeed remains focused on three key strategic priorities: advancing technology leadership, demonstrating strict financial discipline, and driving operational excellence. The company aims to return to above-market revenue growth driven by a more diversified customer base and to achieve EBITDA and cash flow profitability in the long term. Wolfspeed anticipates solid-state transformers to become a significant driver of future silicon carbide demand over time. The company is positioning itself to capture growth and expand earnings power as the market environment improves. | Updates On ThemeU.S. | Broader Themes EmergingThe leveraging of AI within operations is an emerging broader theme, as Wolfspeed has expanded its partnership with Snowflake to unify factory, supply chain, and enterprise data on a single platform, deploying AI-driven tools for real-time insights and faster decision-making. | Bullish-Leaning Quotes (Short)We are pleased to see that our strategy is building meaningful momentum. These innovations, particularly 10-kilovolt will help to cement Wolfspeed's position as a leader in high-voltage applications. AI applications with approximately 30% sequential growth from Q2 to Q3 and increasing customer engagement, which gives us confidence in the long-term trajectory of this opportunity. The good news is, quite frankly speaking, that the restructuring on our, let's say, device side is done. | Bearish-Leaning Quotes (Short)Global EV adoption continues to grow, though more modestly in certain regions. While it represents a moderate portion of our business today, we have continued to see strong sequential growth in AI applications. Near-term demand in automotive remains uncertain. We expect non-GAAP gross margin to remain negative in the fourth quarter. Underutilization continues to be the primary driver of our gross margin profile. | HiringWolfspeed has completed recent leadership additions, including Daihui Yu as Regional President for Greater China, Stefan Steyerl as Vice President of Sales for EMEA, and Yasuhisa Harita as Regional President for Asia Pacific. Headcount reduction actions are largely complete, and the company expects to maintain approximately the current level of OpEx moving into the next quarter. |
