Contract miner and construction group Macmahon Holdings has forecast 20 per cent profit growth in fiscal 2013 amid strong orders.

Macmahon on Monday reported a 45 per lift in full year net profit to a record $56.1 million for the year to June 30, thanks to its strong exposure to the resources sector.

Its share price was up four cents at 66.5 cents at 1521 AEST.

Chief executive Nick Bowen said his company’s diversified business strategy was now well advanced and that operations were continuing to expand across project types, markets and industry sectors.

“This business model positions the company to tackle changing market conditions, while maintaining its commitment to delivering sustainable returns to shareholders,” Mr Bowen said in a statement.

“The outlook is positive for the year ahead, with a strong order book, robust tender pipeline and healthy working relationships with our clients.”

Much of the order book for the company, which is 20 per cent owned by Leighton Holdings, was already secured for this financial year.

“The company expects 20 per cent profit growth for the year ahead,” Mr Bowen said.

Revenue was up 52.2 per cent to $1.87 billion from $1.25 billion in the prior year.

The company’s mining tendering pipeline remained robust due to blue-chip client base, while international opportunities would enhance long-term growth prospects and profitability, the company said.

Macmahon has $1.4 billion of revenue secured for fiscal 2013, which is expected to increase to $1.7 billion.

The company says the most immediate growth will be driven by mining-related construction in Western Australia and the Northern Territory, with work expected to peak in 2014.

During the year Macmahon increased its number of direct employees from 3500 to almost 4800 people.

The company declared a fully franked final dividend of 2.5 cents.
