Shares in Mediclinic on the JSE closed 13.3 percent higher to R141.02 on Friday, on course for their biggest one-day gain in more than two years.
On Thursday, the stock gained nearly 20 percent in London, where it has a primary listing.
The Abu Dhabi government cancelled a requirement for citizens to make a 20 percent co-payment for treatment at private medical facilities, official news agency WAM said late on Wednesday, buoying Mediclinic’s London shares.
The move is a major boost for Mediclinic, which paid $2.2 billion (R29.32 billion) for United Arab Emirates-based Al-Noor hospital in 2015 to bulk up its presence in the fast-growing market.
But in July last year Abu Dhabi cut insurance coverage under its Thiqa plan to 80 percent from 100 percent, meaning patients had to pay 20 percent of bills at private hospitals.
