Proton Holdings

Proton Holdings Berhad, commonly known as Proton (stylised PROTON), is a Malaysian multinational automotive company. Proton was established on May 7, 1983, as Malaysia's sole national badged car company until the advent of Perodua in 1993. The company is headquartered in Shah Alam, Selangor, and operates additional facilities in Proton City, Perak.

Proton began manufacturing rebadged versions of Mitsubishi Motors (MMC) products in the 1980s and 1990s. Proton produced its first indigenously designed, non-badge-engineered car in 2000 with a Mitsubishi engine. It elevated Malaysia as the 11th country in the world with the capability to design cars from the ground up. Since the 2000s, Proton has produced a mix of locally engineered and badge-engineered vehicles.

Proton was founded under majority ownership by HICOM, with a minority stake being held by Mitsubishi Group members. By 2005, Mitsubishi had divested its stake in Proton to Khazanah Nasional. In 2012, Proton was fully acquired by DRB-HICOM. Proton was the owner of Lotus Cars from 1996 to 2017. In May 2017, DRB-HICOM announced plans to sell a 49.9% stake in Proton and a 51% stake in Lotus to Geely Automobile Holdings. The deal was signed in June 2017, and Lotus has ceased to be a unit of Proton.

As of 2023, Proton has an overseas presence in Bangladesh, Bermuda, Brunei, Egypt, Iraq, Jordan, Kenya, Mauritius, Mozambique, Nepal, Pakistan, Papua New Guinea, Sri Lanka, South Africa and Zimbabwe. CKD plants are located in Pakistan, Kenya, Nepal and Sri Lanka.
