· The South African
On 1 July 2026, Johann Rupert’s Remgro finalised the purchase of Mediclinic. The process began in December 2025, but took months and plenty of financial manoeuvres to complete.
This purchase gives the South African billionaire a greater stake in South Africa’s privatised healthcare industry.

Johann Rupert’s Deal to Buy Mediclinic
When the deal to purchase Mediclinic was announced, Remgro and IHL each agreed to pay $950 million (R15.52 billion) to complete the transaction. In exchange, each company would get 100% ownership in its region’s private healthcare company.
Previously, Remgro and IHL split ownership 50-50 between two companies: Swiss-based Hirslanden and South Africa’s Mediclinic International.
But as part of the deal, IHL would acquire Remgro’s stake in Hirslanden, and Remgro would acquire IHL’s portion of Mediclinic.
According to Business Insider Africa, despite the announcement that Remgro would pay IHL $950 million (R15.52 billion), they paid $947 million (R15.52 billion) to acquire full control of Mediclinic. IHL paid a little over $1 billion (R18.03 billion) to acquire a 100% stake in Hirslanden.
