You can tell Regional Express Holdings (REX) is trying hard to control their optimism at AGM when it predicted that FY15's profit will be better than FY14's. Fact is there is a good chance this year's profit will be very materially higher even if operating conditions stay flat. The removal of the carbon tax will add 23.4% to pre-tax profit (based on FY14 numbers), while the drop in jet fuel price (assuming it averages around current levels and depending on FX) could add over $6m to its bottom line. That's significant given that its FY14 pre-tax earnings was $10.7m. Further, REX had huge capex of $56m in FY14, most of which is one-off.
