Z Energy has increased its full-year earnings guidance by more than $15 million due to improved margins following the sharp drop in oil prices late last year.
The country's biggest fuel retailer said falling crude prices and resulting reduction in pressure on margins will enable it to deliver operating earnings of between $420m and $450m for the year ending March 31.
In November the firm had cut its guidance to $400-to-$435m, citing pricing pressures.
The firm today also increased its dividend forecast, citing increased December quarter earnings and a more stable outlook for crude oil prices. It is expecting to pay total dividends of between 38 and 47 cents for the year, up from the 32-to-41 cents signalled in November.
Z shares have risen strongly this month and last traded at $5.81. They are down almost 23 per cent during the past year.
