Proton is a Malaysian automobile manufacturer headquartered in Shah Alam, Selangor, with a manufacturing plant in Tanjung Malim, Perak. Founded in 1983, it was Malaysia's only carmaker until the establishment of its competitor Perodua in 1993. Its name is a Malay acronym for PeRusahaan OTOmobil Nasional (English: National Automobile Enterprise).
It is a core member of Proton Holdings Berhad, the holding company which is listed on Bursa Malaysia. Over 42% of its equity is owned by a government-owned company Khazanah Nasional Berhad, making it government-linked. For more than a decade since its establishment, this stake was jointly owned by Mitsubishi Motors Corporation and Mitsubishi Corporation until they sold its stake in that company.
