Wolfspeed makes silicon carbide chips and power devices that help electric vehicles, industrial equipment, and energy systems run more efficiently.
Wolfspeed makes the special chips that let electricity flow with less waste. Its main product is silicon carbide semiconductors, a material that handles high power and high heat far better than ordinary silicon. Carmakers use these chips in electric vehicles to squeeze more driving range out of the same battery, and industrial and energy customers use them in things like solar inverters, fast chargers, and power supplies. The company also makes gallium nitride devices for radio and power applications.
The business has two big parts. One makes the raw silicon carbide material and the wafers that chips are built on. The other turns those wafers into finished power devices that customers design into their products. This gives Wolfspeed a rare level of control: it can make the material, the wafer, and the chip. Customers choose it largely because silicon carbide is hard to make well at scale, and Wolfspeed has been doing it longer than almost anyone. The story behind the name is a classic corporate reinvention. For decades the company was known as Cree, a North Carolina firm that made LED lighting and the materials behind it. As LEDs became a commodity, Cree bet its future on silicon carbide power chips, renamed itself Wolfspeed in 2021, and sold off the lighting business. That bet came with a very expensive tab: the company built huge new factories in upstate New York and North Carolina to make the wafers and chips itself.
That spending is the heart of the risk. Wolfspeed has poured billions into factories before its customers' demand fully arrived, and it has posted heavy losses while carrying a large debt load. It competes with much bigger chipmakers, including Infineon, STMicroelectronics, and onsemi, and its results swing with the pace of electric vehicle sales. When EV demand cooled, the company had to cut costs and slow some expansion. It is a genuine technology leader, but one whose future depends on turning those big factories into steady, profitable volume.
