The business "continues to navigate an environment characterised by elevated competitive intensity and ongoing pressure on consumers", MTN Group said in its interim results to 30 June 2025, published on Monday.
"The medium-term target for service revenue growth has been revised to 'low to mid-single-digit' growth from 'mid-single-digit'," the group said.
Alongside the revised service revenue target, MTN South Africa has adjusted its forecast Ebitda margin range from 37-39 to 35-37. MTN's less optimistic outlook comes as performance figures for the South African subsidiary show a period of stagnation in the first half of the year.
