Toshiba Corporation (株式会社東芝, Kabushiki gaisha Tōshiba, English: /təˈʃiːbə, tɒ-, toʊ-/) is a Japanese multinational conglomerate headquartered in Tokyo, Japan. Its diversified products and services include information technology and communications equipment and systems, electronic components and materials, power systems, industrial and social infrastructure systems, consumer electronics, home appliances, medical equipment, office equipment, as well as lighting and logistics.
Toshiba was founded in 1939 as Tokyo Shibaura Denki K.K. (Tokyo Shibaura Electric Co., Ltd) through the merger of Shibaura Seisaku-sho (founded in 1875) and Tokyo Denki (founded in 1890). The company name was officially changed to Toshiba Corporation in 1978.
It is listed on the Tokyo Stock Exchange, where it was a constituent of the Nikkei 225 and TOPIX indices (leaving both in August 2018), the Nagoya Stock Exchange, and the London Stock Exchange. Toshiba is the ninth-largest semiconductor manufacturer in the world. In 2017, Toshiba filed unaudited quarterly results because of uncertainties at Westinghouse, which had filed for Chapter 11 bankruptcy protection. Toshiba stated that "substantial doubt about the company's ability to continue as a going concern exists".
Toshiba is organized into four groupings: the Digital Products Group, the Electronic Devices Group, the Home Appliances Group, and the Social Infrastructure Group. Midea Group, a Chinese company, bought a controlling 80.1% stake in the Toshiba Home Appliances Group in 2016.
