Sasol, the world's biggest producer of fuels and chemicals from coal and gas, said it sees headline earnings per share (HEPS) between 17.90 rand and 22.22 rand ($0.9445-$1.17) in the six months to Dec.31, compared to 30.90 rand previously.
While the company noted some operational improvements in South Africa, it said the underperformance of state-owned utilities involved in its value chain and a weaker global growth outlook continue to impact its business.
Sasol is scheduled to release its half-year results on Feb.26.
