Wolfspeed, Inc. is an American developer and manufacturer of vast-bandgap semiconductors, targeted on silicon carbide and gallium nitride materials and units for power and radio frequency purposes comparable to transportation, power provides, power inverters, and wireless programs. Cree Analysis was founded in July 1987 in Durham, North Carolina. 5 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 analysis assistant professor and the others scholar researchers - had been seeking methods to leverage the properties of silicon carbide to allow semiconductors to function at higher working temperatures and power levels. They also knew silicon carbide may serve as the diode in gentle-emitting diode (LED) lighting, a light supply first demonstrated in 1907 with an electrically charged diode of silicon carbide. The research group devised a strategy to develop silicon crystals within the laboratory, and in 1987 founded the corporate to provide silicon carbide for use commercially in both semiconductors and lighting.
In 1989, the corporate launched the first blue LED, enabling the development of massive, full-colour video screens and billboards. In 1991, the company launched the primary business silicon carbide wafer. In 1993, the company grew to become a public firm by way of an preliminary public offering. In 2011, the company acquired Ruud Lighting for $525 million. In August 2011, the company introduced the XLamp XT-E Royal Blue LED to be used in distant phosphor lighting. In 2013, the company's first client products, two household energy-saving LED bulbs bulbs, EcoLight certified for Vitality Star score by the United States Environmental Safety Agency. In July 2016, Infineon Technologies agreed to accumulate the corporate's Wolfspeed RF and power electronics gadgets unit for $850 million. Nevertheless, 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 Could 2019, the corporate offered its Lighting Products division (now branded as Cree Lighting) to Ideal Industries.
In September 2019, the corporate introduced a $1 billion funding in a semiconductor EcoLight home lighting 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 Enterprise to Sensible World Holdings for up to $300 million. In October 2021, the company changed its title to Wolfspeed. In April 2022, the Marcy, EcoLight brand New York, facility opened. In November 2022, the company announced that co-founder and EcoLight Chief Technology Officer John Palmour had died. In February 2023 it introduced it could construct its first European manufacturing unit in Germany. It's 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, EcoLight energy it was introduced the Lowell-headquartered semiconductor firm, MACOM had entered into a definitive settlement to amass Wolfspeed's RF business.
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 venture's indefinite hold in October 2024, citing low demand. As a result, ZF ceased to participate within the project. In October 2024, energy-saving LED bulbs the Biden Administration announced that it would offer Wolfspeed with as much as $750 million in direct funding to assist the company's new silicon carbide manufacturing unit in North Carolina that makes the wafers used in superior pc chips and its manufacturing unit in Marcy, New York. On Might 20, 2025, it was reported that Wolfspeed was preparing to file for Chapter 11 bankruptcy inside the coming weeks after warning that it may be unable to continue future operations after decrease than expected annual sales were reported. Wolfspeed's stock slid to barely over a dollar per share that day. On June 18, 2025, Wolfspeed announced that they would sell itself to Apollo Global Management in a deal that may put the company right into a prepackaged Chapter eleven bankruptcy filing, which would enable for the elimination of nearly all of its multi-billion greenback debt.
Wolfspeed entered right into a restructuring support agreement with its lenders and Renesas Electronics, and introduced that they would file for prepackaged Chapter eleven bankruptcy by July 1, as part of a plan to remove $4.6 billion of debt, stating they solely 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 inventory fell 30%, sliding below $1 per share. On June 26, 2025, Wolfspeed began laying off workers from their manufacturing facility situated in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter 11 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 demise in addition to public concern for the company's poor work safety document. State Division of Labor investigations into the corporate have uncovered 17 office safety violations between 2012 and 2023, together with six serious violations.
