Cree Inc is a North Carolina Corporation established in 1987. The Company manufactures lighting-class light emitting diode (LED) products, lighting products and semiconductor products for power and radio-frequency (RF) applications. Its products are used in applications such as indoor and outdoor lighting, video displays, transportation, electronic signs and signals, power supplies, solar inverters and wireless systems. It develops and manufactures semiconductor materials and devices mainly based on silicon carbide (SiC), gallium nitride (GaN) and related compounds. The physical and electronic properties of SiC and GaN offer technical advantages over traditional silicon, gallium arsenide (GaAs) and other materials used for electronic and opto-electronic applications. The Company has three reportable segments: LED Products, Lighting Products, Power and RF Products. Its LED products consist of LED components, LED chips, and SiC wafers. Its lighting products consist of both LED and traditional lighting systems. It designs, manufactures and sells lighting systems for indoor and outdoor applications, with its main focus on LED lighting systems for the commercial and industrial markets. It also uses its LED systems expertise to accelerate LED lighting adoption and expand the market for its LED components. In addition, it develops, manufactures and sells power and RF devices. Its power products are made from SiC and provide faster switching speeds than comparable silicon-based power devices for a given power level. Its RF devices are made from GaN and produce higher power densities as compared to silicon or gallium arsenide. The majority of its products are manufactured at its production facilities located in North Carolina, Wisconsin, and China. It also uses contract manufacturers for certain aspects of product fabrication, assembly and packaging. It operates research and development facilities in North Carolina, California, Wisconsin, and China. Its LED Products segment's main competitors are Nichia Corporation (Nichia), OSRAM Semiconductor GmbH (OSRAM), Koninklijke Philips Electronics N.V. (Philips), and Samsung LED Company (Samsung). The Company's Lighting Products segment currently faces competition from traditional lighting fixture companies, lamp manufacturers and from non-traditional companies focused on LED lighting systems including fixtures and lamps. Lighting companies are Acuity Brands, Inc., Cooper Industries plc, General Electric Company, Hubbell Incorporated, Philips, and OSRAM. Its SiC-based power devices compete with similar devices offered by Infineon Technologies AG, STMicroelectronics, Inc. and Rohm Co., Ltd. The Company is subject to a variety of federal, state and local provisions regulating the discharge of materials into the environment or otherwise relating to the protection of the environment.
