JSE-listed energy and chemicals multinational Sasol says it expects to report a 2% to 16% year-on-year decrease in adjusted earnings before interest, taxes, depreciation and amortisation (Ebitda) to between R60.6-billion and R70.6-billion for the financial year ended June 30. In a trading statement ahead of the August 23 publication of its results, the company says its financial results were impacted by a combination of operational challenges and a volatile global economic landscape, which included weaker global economic growth, higher inflation, depressed chemicals prices and higher feedstock and energy costs.
