What Wolfspeed does
Wolfspeed, Inc. (formerly Cree, Inc., rebranded in 2021) is a Durham, North Carolina-based vertically integrated silicon carbide (SiC) semiconductor company founded in 1987. It produces SiC substrate materials (150mm and 200mm wafers), discrete MOSFETs and Schottky diodes, bare die products, and power modules spanning 1200V to 10 kV ratings — including the industry's first commercially available 10 kV SiC MOSFET and Gen 5 MOSFET technology offering up to 27% efficiency improvement. The company operates what it describes as the first U.S.-based SiC corridor, with end-to-end substrate and power device fabrication centered on the Mohawk Valley, New York 200mm device fab, following the early 2026 shutdown of the older Durham 150mm facility.
The company sells primarily through direct enterprise sales to major OEMs and Tier 1 suppliers across automotive (Toyota), renewable energy (Hopewind), aerospace and defense (GE Aerospace), and emerging AI data center customers (Amperesand), supplemented by an authorized distributor network and an online sample center for engineering evaluation. Revenue is hardware-driven, quote-based, and project-specific, particularly for automotive qualification programs; pricing is not publicly disclosed. Wolfspeed holds over 2,300 issued and pending patents and is the only pure-play vertically integrated SiC company at scale.
Following a Chapter 11 filing in June 2025, Wolfspeed emerged from bankruptcy on September 29, 2025 with a 70% debt reduction (from $13.6 billion to approximately $1.7 billion), shifting from a primarily EV-focused business toward a diversified mix that includes AI data center power infrastructure, aerospace and defense applications, industrial motor drives, and renewable energy systems. Post-restructuring ownership is concentrated among creditors, with Renesas Electronics America holding a $293.4 million CFIUS-cleared equity stake and institutional investors including T. Rowe Price and Fidelity Management & Research participating in subsequent refinancings.

Wolfspeed competitors and assessment
Company assessmentDirect peers
- ROHM Semiconductor: ROHM is a Japanese SiC power device manufacturer offering 4th-generation SiC MOSFETs, Schottky diodes, and integrated modules. ROHM is a direct competitor in automotive and industrial SiC markets and was an early SiC pioneer.
- Infineon Technologies: Infineon is Wolfspeed's largest direct competitor in SiC power semiconductors, offering CoolSiC MOSFETs, discretes, modules, and bare die products for automotive, industrial, and renewable energy. Both companies target the same EV inverter and industrial drive customers and compete head-to-head on 1200V/1700V SiC MOSFETs.
- STMicroelectronics: STMicroelectronics is one of the leading SiC power device manufacturers with its STPOWER SiC portfolio including MOSFETs, diodes, and modules. It supplies Tesla and other major automotive OEMs and competes directly with Wolfspeed across automotive traction inverters and industrial power conversion.
- Renesas Electronics: Renesas acquired a $293.4M equity stake in Wolfspeed during restructuring and also offers SiC power products through its acquired Dialog/Intersil portfolio. Renesas is both an investor and a strategic competitor in automotive and industrial power semiconductors.
- ON Semiconductor: ON Semiconductor (onsemi) is a leading SiC power semiconductor competitor with its EliteSiC family of MOSFETs and modules. The company is rapidly scaling SiC capacity and competing with Wolfspeed in automotive traction inverters, on-board chargers, and industrial applications.
Emerging players
