MACA Ltd. revised earnings guidance for the year 2015. For the year, the company expects revenue guidance for the 2015 financial year from in excess of $650 million to approximately $620 million. Whilst this lower revenue expectation will affect the earnings outlook, the company anticipates net profit for the year will exceed that which was achieved in fiscal year 2014.

The revenue downgrade follows advice received from Arrium Ltd. that its project in South Australia in the Southern Iron region would be 'mothballed'.
