Aug 26 (Reuters) - Australia's oil and gas company Viva Energy Group VEA.AX on Monday posted a 43.4% drop in its first half underlying profit, hurt by weakness in its refining business.
Underlying profit after tax attributable at replacement cost basis for the six months ended 30 June came in at A$50.9 million compared with A$90.0 million a year ago on a pro-forma basis.
The company declared an interim dividend of 2.1 cents per share.
