WOLF

Wolfspeed, Inc.

A maker of silicon carbide and gallium nitride semiconductors, Wolfspeed produces the wafers and power devices—diodes, MOSFETs, and modules—that help electric vehicles, fast chargers, and renewable energy systems move electricity efficiently. Founded in 1987 by North Carolina State University graduates as Cree, Inc., it rebranded as Wolfspeed in 2021, a name that nods to the NC State Wolfpack. In 2025 it filed for Chapter 11 bankruptcy protection to reorganize its debts.
