The company's board also approved acquiring stake in four companies through its units.
Elsewhere, telecoms firm Etisalat was up 0.5%.

Saudi Arabia's benchmark index added 0.3%, with Jabal Omar Development, one of Saudi Arabia's largest listed property developers, rebounding over 3%.

In Dubai, the main share index rose 0.7%, buoyed by gains in property shares. Emaar Properties , Dubai's biggest developer, advanced 1.8%, while its shopping centre unit Emaar Malls traded 2.6% higher.
