South African billionaire Johann Rupert has strengthened his grip on the country’s private healthcare industry after investment holding company Remgro completed its $947 million (R15.56 billion) acquisition of full ownership of Mediclinic Southern Africa.

The transaction, finalised on July 1 after receiving all required regulatory approvals, gives Remgro sole ownership of one of Southern Africa’s largest private hospital groups, ending a long-standing joint ownership structure with Luxembourg-based Investment Holding Limited (IHL).

Before the restructuring, Remgro and IHL each owned 50% of Mediclinic Holdings.

Under the agreement, Remgro assumes full ownership of Mediclinic’s Southern African operations through Mediclinic International, while IHL takes complete ownership of the group’s Swiss business, Hirslanden.

The separation allows both shareholders to pursue independent strategies tailored to their respective markets without the complexity of shared governance.
