Wolfspeed

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.
