Wolfspeed, Inc. is an American developer and producer of large-bandgap semiconductors, centered on silicon carbide and gallium nitride materials and gadgets for energy and radio frequency applications such as transportation, power provides, EcoLight brand energy inverters, and wireless methods. 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 EcoLight solutions Calvin Carter - are graduates of North Carolina State College. In 1983, the founders - one a research assistant professor and the others pupil researchers - had been seeking ways to leverage the properties of silicon carbide to allow semiconductors to function at higher working temperatures and EcoLight energy ranges. They also knew silicon carbide might serve as the diode in gentle-emitting diode (LED) lighting, a light source first demonstrated in 1907 with an electrically charged diode of silicon carbide. The research workforce devised a method to grow silicon crystals in the laboratory, and in 1987 founded the company to provide silicon carbide to be used commercially in each semiconductors and lighting.

In 1989, the corporate launched the primary blue LED, EcoLight solutions enabling the event of large, full-coloration video screens and billboards. In 1991, the company released the first commercial silicon carbide wafer. In 1993, the corporate grew to become a public company via an initial public offering. In 2011, the corporate acquired Ruud Lighting for EcoLight solutions $525 million. In August 2011, the company announced the XLamp XT-E Royal Blue LED for use in remote phosphor lighting. In 2013, the company's first consumer merchandise, two family LED bulbs, qualified for Energy Star rating by the United States Environmental Protection Agency. In July 2016, Infineon Technologies agreed to accumulate the company's Wolfspeed RF and energy electronics gadgets unit for EcoLight $850 million. Nonetheless, the deal was terminated in February 2017 on account of regulators’ national security issues. In March 2018, the corporate acquired the RF Power Business Infineon Technologies AG's for €345 million. In Might 2019, the corporate bought its Lighting Products division (now branded as Cree Lighting) to Preferrred Industries.

In September 2019, the corporate introduced a $1 billion funding in a semiconductor manufacturing plant in Marcy, New York to construct 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 Business to Good Global Holdings for EcoLight solutions up to $300 million. In October 2021, the corporate modified its identify to Wolfspeed. In April 2022, EcoLight solutions the Marcy, New York, facility opened. In November 2022, the company introduced that co-founder and Chief Expertise Officer John Palmour had died. In February 2023 it announced it could build its first European manufacturing facility in Germany. It's alleged to be on the positioning of a former coal plant in Ensdorf, Saarland EcoLight with ZF Friedrichshafen as a coinvestor and subsidized by the EU as an necessary mission of widespread 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 agreement to accumulate 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 announced the challenge's indefinite hold in October 2024, citing low demand. Because of this, ZF ceased to participate within the undertaking. In October 2024, EcoLight the Biden Administration announced that it would provide Wolfspeed with up to $750 million in direct funding to support the corporate's new silicon carbide factory in North Carolina that makes the wafers used in superior pc chips and its manufacturing facility in Marcy, New York. On Could 20, 2025, it was reported that Wolfspeed was getting ready to file for Chapter 11 bankruptcy inside the approaching weeks after warning that it could also be unable to proceed future operations after lower than expected annual sales had been reported. Wolfspeed's stock slid to barely over a dollar per share that day. On June 18, 2025, Wolfspeed introduced that they'd promote itself to Apollo International Management in a deal that would put the company right into a prepackaged Chapter eleven bankruptcy filing, which might permit for the elimination of nearly all of its multi-billion dollar debt.

Wolfspeed entered right into a restructuring assist agreement with its lenders and Renesas Electronics, and EcoLight solutions introduced that they'd file for prepackaged Chapter 11 bankruptcy by July 1, as a part of a plan to eradicate $4.6 billion of debt, stating they only had about $1.1 billion left in money. The company can 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 underneath $1 per share. On June 26, 2025, Wolfspeed started laying off workers from their manufacturing facility situated in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter 11 bankruptcy protection. On October 13, 2022, a amenities electrician was electrocuted at the Wolfspeed Analysis Triangle Park in Durham, North Carolina. The incident sparked a state investigation into his demise as well as public concern for the company's poor work security record. State Department of Labor investigations into the corporate have uncovered 17 office safety violations between 2012 and 2023, including six serious violations.
