The company, which agreed to be acquired by Canada's Brookfield Asset Management in June, reported a profit for the six months ended June 30 of $34.9 million, up from about $32 million a year earlier.

Profits were, however, slightly offset by higher net interest expense due to rising benchmark rates and a higher effective tax rate on growing profits across Africa, the company added.
