The company was formed as Investec Asset Management in 1991.[3] It changed its name to Ninety One in spring 2020: the new name is in recognition of the brand's heritage, as it was in 1991 that the investment firm was started in South Africa.[4]
The company was demerged from Investec in March 2020.[5] It had been envisaged that 10% of the stock would be offered to the public but Investec decided to retain 25% (rather than just 15% as originally planned) because of market conditions.[5]
Ninety One managed US$159 billion in assets as of 31 December 2022.[6]
