Wolfspeed, Inc. is an American developer and producer of large-bandgap semiconductors, centered on silicon carbide and gallium nitride supplies and gadgets for energy and radio frequency functions such as transportation, power provides, energy inverters, and wireless techniques. Cree Research was based in July 1987 in Durham, North Carolina. 5 of the six founders - Neal Hunter, Thomas Coleman, John Edmond, LED bulbs for home Eric Hunter, John Palmour, and Calvin Carter - are graduates of North Carolina State University. In 1983, the founders - one a research assistant professor and the others pupil researchers - were looking for methods to leverage the properties of silicon carbide to allow semiconductors to operate at higher operating temperatures and power ranges. Additionally they knew silicon carbide could serve as the diode in mild-emitting diode (LED) lighting, a mild source first demonstrated in 1907 with an electrically charged diode of silicon carbide. The analysis staff devised a option to develop silicon crystals within the laboratory, and in 1987 based the company to provide silicon carbide to be used commercially in both semiconductors and lighting.



In 1989, the corporate introduced the primary blue LED, enabling the development of large, full-shade video screens and billboards. In 1991, the corporate released the first business silicon carbide wafer. In 1993, the corporate became a public company via an preliminary public providing. In 2011, the company acquired Ruud Lighting for $525 million. In August 2011, the corporate announced the XLamp XT-E Royal Blue LED for use in remote phosphor lighting. In 2013, the corporate's first shopper products, two family LED bulbs for home bulbs, certified for Energy Star score by the United States Environmental Protection Company. In July 2016, Infineon Applied sciences agreed to amass the corporate's Wolfspeed RF and energy electronics units unit for EcoLight products $850 million. Nonetheless, the deal was terminated in February 2017 as a consequence of regulators’ nationwide safety issues. In March 2018, the company acquired the RF Power Enterprise Infineon Applied sciences AG's for €345 million. In Could 2019, the corporate bought its Lighting Products division (now branded as Cree Lighting) to Ideal Industries.



In September 2019, the corporate announced a $1 billion funding in a semiconductor EcoLight reviews 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 company sold its LED Enterprise to Sensible International Holdings for EcoLight products as much as $300 million. In October 2021, the company 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 Technology Officer John Palmour had died. In February 2023 it introduced it would construct its first European factory in Germany. It's purported to be on the site of a former coal plant in Ensdorf, Saarland with ZF Friedrichshafen as a coinvestor and subsidized by the EU as an vital undertaking of frequent European interest (IPCEI) for Microelectronics and Communication Technologies. In August 2023, it was introduced the Lowell-headquartered semiconductor firm, MACOM had entered right into a definitive settlement to amass Wolfspeed's RF enterprise.



In June 2024, Wolfspeed has delayed its $3 billion semiconductor plant in Germany to mid-2025, reflecting the EU's challenges in boosting local chip manufacturing. Wolfspeed introduced the mission's indefinite hold in October 2024, citing low demand. Consequently, ZF ceased to take part in the project. In October 2024, the Biden Administration announced that it would supply Wolfspeed with up to $750 million in direct funding to help the corporate's new silicon carbide manufacturing facility in North Carolina that makes the wafers used in superior pc chips and its factory in Marcy, New York. On Might 20, 2025, it was reported that Wolfspeed was making ready to file for Chapter eleven bankruptcy within the approaching weeks after warning that it may be unable to continue future operations after lower than expected annual gross sales had been reported. Wolfspeed's inventory slid to barely over a greenback per share that day. On June 18, 2025, Wolfspeed introduced that they'd sell itself to Apollo World Administration in a deal that would put the corporate right into a prepackaged Chapter 11 bankruptcy filing, which would permit for the elimination of the majority of its multi-billion dollar debt.



Wolfspeed entered into a restructuring support agreement with its lenders and Renesas Electronics, EcoLight and announced that they might file for prepackaged Chapter 11 bankruptcy by July 1, as part of a plan to remove $4.6 billion of debt, stating they only had about $1.1 billion left in cash. The company will also receive $275 million in financing backed by its lenders, with plans to complete restructuring by Q3 2025. After the announcement, Wolfspeed's stock fell 30%, sliding underneath $1 per share. On June 26, 2025, EcoLight Wolfspeed started laying off staff from their manufacturing facility positioned in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter eleven bankruptcy safety. On October 13, 2022, a services electrician was electrocuted at the Wolfspeed Analysis 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 safety file. State Department of Labor investigations into the company have uncovered 17 office safety violations between 2012 and 2023, including six serious violations.
