Wolfspeed, Inc. is an American developer and producer of large-bandgap semiconductors, focused on silicon carbide and EcoLight gallium nitride materials and gadgets for power and radio frequency purposes akin to transportation, energy provides, energy inverters, and wireless systems. Cree Analysis was founded in July 1987 in Durham, North Carolina. Five of the six founders - Neal Hunter, Thomas Coleman, John Edmond, Eric Hunter, John Palmour, and Calvin Carter - are graduates of North Carolina State College. In 1983, the founders - one a research assistant professor and the others pupil researchers - have been in search of methods to leverage the properties of silicon carbide to enable semiconductors to operate at increased working temperatures and power ranges. Additionally they knew silicon carbide may serve because the diode in gentle-emitting diode (LED) lighting, a mild source first demonstrated in 1907 with an electrically charged diode of silicon carbide. The research staff devised a way to develop silicon crystals within the laboratory, and in 1987 based the corporate to supply silicon carbide to be used commercially in both semiconductors and EcoLight home lighting.

In 1989, the company launched the first blue LED, enabling the event of massive, full-coloration video screens and billboards. In 1991, EcoLight the company launched the first industrial silicon carbide wafer. In 1993, the corporate became a public firm by way of an initial public providing. In 2011, the company acquired Ruud Lighting for $525 million. In August 2011, the company announced the XLamp XT-E Royal Blue LED for use in distant phosphor lighting. In 2013, the company's first client products, two family LED bulbs, certified for Vitality Star ranking by the United States Environmental Safety Company. In July 2016, Infineon Technologies agreed to accumulate the corporate's Wolfspeed RF and energy electronics devices unit for $850 million. However, the deal was terminated in February 2017 as a consequence of regulators’ national safety considerations. In March 2018, the corporate acquired the RF Power Enterprise Infineon Applied sciences AG's for €345 million. In May 2019, the corporate bought its Lighting Products division (now branded as Cree Lighting) to Ideally suited Industries.

In September 2019, the corporate announced a $1 billion investment in a semiconductor manufacturing plant in Marcy, New York to build the world’s largest silicon carbide fabrication facility with a $500 million grant from New York State. In March 2021, the corporate bought its LED Business to Smart International Holdings for as much as $300 million. In October 2021, the corporate modified its identify to Wolfspeed. In April 2022, the Marcy, New York, facility opened. In November 2022, the corporate announced that co-founder and Chief Expertise Officer John Palmour had died. In February 2023 it announced it might build its first European manufacturing unit in Germany. It is presupposed to be on the location of a former coal plant in Ensdorf, Saarland with ZF Friedrichshafen as a coinvestor and subsidized by the EU as an vital project of widespread European curiosity (IPCEI) for Microelectronics and Communication Applied sciences. In August 2023, it was announced the Lowell-headquartered semiconductor company, MACOM had entered into a definitive agreement to amass Wolfspeed's RF business.

In June 2024, Wolfspeed has delayed its $three billion semiconductor plant in Germany to mid-2025, reflecting the EU's challenges in boosting local chip production. Wolfspeed introduced the mission's indefinite hold in October 2024, citing low demand. Because of this, ZF ceased to take part in the venture. In October 2024, the Biden Administration introduced that it would offer Wolfspeed with as much as $750 million in direct funding to support the corporate's new silicon carbide manufacturing unit in North Carolina that makes the wafers utilized in advanced computer chips and its manufacturing unit in Marcy, New York. On Might 20, 2025, it was reported that Wolfspeed was getting ready to file for Chapter eleven bankruptcy inside the coming weeks after warning that it could also be unable to continue future operations after lower than anticipated annual sales have been reported. Wolfspeed's inventory slid to barely over a greenback per share that day. On June 18, 2025, Wolfspeed announced that they would promote itself to Apollo Global Administration in a deal that would put the company right into a prepackaged Chapter eleven bankruptcy filing, which might permit for the elimination of the majority of its multi-billion dollar debt.

Wolfspeed entered right into a restructuring assist agreement with its lenders and Renesas Electronics, and introduced that they would file for prepackaged Chapter eleven bankruptcy by July 1, as a part of a plan to remove $4.6 billion of debt, stating they only had about $1.1 billion left in money. The company may even obtain $275 million in financing backed by its lenders, with plans to finish restructuring by Q3 2025. After the announcement, Wolfspeed's stock fell 30%, sliding beneath $1 per share. On June 26, 2025, Wolfspeed started laying off staff from their manufacturing facility positioned in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter eleven bankruptcy protection. On October 13, 2022, a facilities electrician was electrocuted at the Wolfspeed Research Triangle Park in Durham, North Carolina. The incident sparked a state investigation into his loss of life as well as public concern for the company's poor work security file. State Division of Labor investigations into the company have uncovered 17 office security violations between 2012 and 2023, together with six severe violations.
