Mining-focused engineer Macmahon Holdings has upgraded its full year profit forecast because of additional work.

Macmahon said on Tuesday it expects net profit for the year to June 30, 2012, to be in excess of $55 million.

In November the company had forecast a full year profit of over $45 million.

“We now expect further success on the work winning front, which will take our full year revenue past $1.7 billion, which will drive the higher profits,” chief executive Nick Bowen said in a statement.

Net profit for the six months to December 31 is forecast to be about $20 million.

Macmahon posted a net profit of $1 million in the 2010/11 financial year, and a $13.2 million loss in the six months to December 31, 2010.

“With a very strong order book and positive trading conditions across the group, Macmahon is now on track to deliver a record profit for the 2012 year,” Mr Bowen said.
