Origin Energy Limited provided earnings guidance for the year ended 30 June 2021. Electricity gross profit is expected to be down $250-290 million year on year (previous guidance $170-220 million reduction). Natural gas gross profit is expected to be down $200-250 million year on year (previous guidance $100-150 million reduction), reflecting the roll off of legacy sales contracts ($70 million, unchanged), repricing of tariffs as well as the impact of lower volume of business sales.
