June 20 (Reuters) - Petrol station and convenience store owner Caltex Australia CTX.AX expects first-half underlying net profit to be less than half of what it was a year ago, citing slowing economic growth in Australia and low refining margins.
Caltax on Thursday said its replacement cost operating profit (RCOP) in the first half ended June 30 is expected to be between A$120 million to A$140 million ($82.6 million - $96.4 million).
It reported RCOP net profit after tax of A$296 million a year ago.
