Carlyle's co-founder and managing director David Rubenstein visited Saudi Arabia in February for an economic conference.
The deal is the second to be finalized by the equity firm's Middle East-North Africa fund in three months. In December, Carlyle invested in Medical Park, Turkey's second largest health care group.
Carlyle says it manages assets of $88.6 billion around the world.
