“Our Pan-African operations are performing strongly with excellent sales growth in Cameroon, Ethiopia and Senegal.
“We are consolidating our success across Africa through commissioning of our 1.5Mta factory in Congo, the tenth country in which we have established operations.
“In our key operations in Nigeria, we have significantly improved our fuel mix and this has helped increase margins across the Group.
“It is especially good for Nigeria because most of the coal we are using is mined in our own country,” it said.
It attributed sales increase to strong brand recognition, increased point of sales branding, improvements in sales and marketing strategies and higher visibility through trade shows.
