South Africa’s Ninety One expands globally
The South African asset manager’s growth was buoyed by stronger market performance and improving client inflows across its global strategies. The rise positions the firm for one of its strongest half-year performances in recent periods.
The latest growth builds on a series of moves aimed at sharpening its operations and expanding its global reach.
Earlier this year, Ninety One, South African asset manager, completed the integration of Sanlam Investments UK’s active asset management business into its platform, extending its footprint across Europe and South Africa.
The company has also streamlined its product lineup, merging several funds, including its Emerging Markets Local Currency Debt strategy, as part of a broader effort to simplify offerings and improve efficiency.
Ninety One strengthens leadership, boosts investor confidence
Leadership changes have accompanied these strategic adjustments. David Knee was named Head of Multi-Asset, while Busisiwe Mabuza joined the board as Senior Independent Director.
The firm said the appointments reflect its focus on strengthening multi-asset and sustainability-linked investment strategies, as institutional clients increasingly seek long-term, diversified solutions.

Shares of Ninety One edged higher in London trading after the update, extending year-to-date gains. Investors appeared encouraged by signs of consistent inflows and improved earnings visibility following a challenging period for asset managers globally.
With assets now topping $200 billion, Ninety One stands among the largest independent managers serving both developed and emerging markets, benefiting from a more stable policy backdrop and gradually improving investor sentiment.
