The company’s businesses in Switzerland, Southern Africa and Dubai all performed as anticipated.
The Abu Dhabi business, however, underperformed due to regulatory changes and certain business and operational challenges.
Mediclinic bought a group of hospitals in Abu Dhabi in 2015 through a reverse takeover of Al Noor Group Hospitals.
However, difficult trading conditions in Abu Dhabi has led to the merged company’s Middle East full year revenue falling 8% to AED3.1bn.
In the group's two biggest regions, Hirslanden, Switzerland and South Africa, revenues rose 3.5% and 6.8% respectively.
Mediclinic expects its share of Spire’s annual £53.6mln to be £12mln after adjusting for the amortisation of intangible assets in the purchase price of the equity investment.
The group, which owns 74 hospitals and 40 clinics, bought its stake in Spire for £432mln in 2015.
Shares rose 4.07% to 766.50p in morning trading.
